  6. Operations and maintenance - Safety challenges

    Energy Technology Data Exchange (ETDEWEB)

    Nielsen, Liv [Oljedirektoratet, Stavanger (Norway)

    1999-07-01

    With the unsteady oil prices and the possible consequences of the deregulation of the European energy markets one may expect further optimization of operating and maintenance costs. One may also expect extended use of various risk-based optimization techniques such as RCM (Reliability Centered Maintenance) and RBI (Risk Based Inspection). This presentation addresses the need for further research and development in this area. Maintenance work is necessary, but it can also create risk. The accident statistics show many examples of this. The Norwegian petroleum industry's ability to learn from previous incidents is questioned. Maintenance staff must be well trained and possess the necessary routines. Technical documentation must be updated. Uncertainties with respect to future oil and gas prices combined with the effect of the deregulation of the European energy markets will lead to even more focus on cost-effective operations and maintenance. The need for long-term research and development is stressed. Risk based techniques such as RCM and RBI are extensively used in the defence industry and the nuclear industry, but applying them to the petroleum industry requires improved risk models. Ageing effects such as corrosion, erosion, fatigue etc. can be expected, but the capability to predict, monitor and control them should be improved. At present, not even the most sophisticated risk analysis can model ageing effects. The importance of efficient use of information technology (IT) is stressed. Improving the product quality and safety often requires new technology and so research and development is important. Close cooperation with the industry is required.

  9. Assessment of Safety Management System Implementation in an Approved Maintenance Organization: A Case Study of Nigeria Operators

    Directory of Open Access Journals (Sweden)

    Kole Osaretin Uhuegho

    2013-10-01

    Full Text Available In this study survey data was used to assess employees’ perceptions of Safety Management System (SMS implementation in an Approved Maintenance Organization (AMO in the aviation industry. AMOs in Nigeria were used as a case study. Results show that over 80% of the population used for this study accord to the existence of plans to implement SMS. However, results indicated a lack of safety management education, training and motivation, which are key concepts that influence all the safety management implementation process. Furthermore, results reveal the lack of skills to analyze risk associated with identified hazard. Internal audit and safety investigation are the main means of safety performance monitoring within the AMO. Hypothetical test was conducted using Chi-square statistic. The results show that there is no significant relationship between the appointment of key personnel and management commitment within an AMO safety management system. Overall, the findings suggest that AMO need to do more to improve the implementation and understanding of SMS within the AMO.

    1999-10-01

    The first Thai Research Reactor (TRR-1) was established in 1961 at the Office of Atomic Energy for Peace (OAEP), Bangkok. The reactor was light water moderated and cooled, using HEU plate-type with U{sub 3}O{sub 8}- Al fuel meat and swimming pool type. The reactor went first critical on October 27, 1962 and had been licensed to operate at 1 MW (thermal). On June 30, 1975 the reactor was shutdown for modification and the core and control system was disassemble and replaced by that of TRIGA Mark III type while the pool cooling system, irradiation facilities and other were kept. Thus the name TRR-1/M1' has been designed due to this modification the fuel has been changed from HEU plate type to Uranium Zirconium Hydride (UZrH) Low Enrichment Uranium (LEU) which include 4 Fuel Follower Control Rods and 1 Air Follower Control Rod. The TRR-1/M1 went critical on November 7, 1977 and the purpose of the operation are training, isotope production and research. Nowadays the TRR-1/M1 has been operated with core loading No.12 which released power of 1,056 MWD. (as of October 1998). The TRR-1/M1 has been operated at the power of 1.2 MW, three days a week with 34 hours per week, Shut-down on Monday for weekly maintenance and Tuesday for special experiment. The everage energy released is about 40.8 MW-hour per week. Every year, the TRR-1/M1 is shut-down about 2 months between February to March for yearly maintenance. (author)

  8. Genetic Enhancer Analysis Reveals that FLORAL ORGAN NUMBER2 and OsMADS3 Co-operatively Regulate Maintenance and Determinacy of the Flower Meristem in Rice.

    Meristems such as the shoot apical meristem and flower meristem (FM) act as a reservoir of stem cells, which reproduce themselves and supply daughter cells for the differentiation of lateral organs. In Oryza sativa (rice), the FLORAL ORGAN NUMBER2 (FON2) gene, which is similar to Arabidopsis CLAVATA3, is involved in meristem maintenance. In fon2 mutants, the numbers of floral organs are increased due to an enlargement of the FM. To identify new factors regulating meristem maintenance in rice, we performed a genetic screening of mutants that enhanced the fon2 mutation, and found a mutant line (2B-424) in which pistil number was dramatically increased. By using a map-based approach and next-generation sequencing, we found that the line 2B-424 had a complete loss-of-function mutation (a large deletion) in OsMADS3, a class C MADS-box gene that is known to be involved in stamen specification. Disruption of OsMADS3 in the fon2 mutant by CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats-CRISPR-associated protein 9) technology caused a flower phenotype similar to that of 2B-424, confirming that the gene responsible for enhancement of fon2 was OsMADS3. Morphological analysis showed that the fon2 and osmads3 mutations synergistically affected pistil development and FM determinacy. We also found that whorl 3 was duplicated in mature flowers and the FM was enlarged at an early developmental stage in severe osmads3 single mutants. These findings suggest that OsMADS3 is involved not only in FM determinacy in late flower development but also in FM activity in early flower development. © The Author 2017.

    Full Text Available Deceased organ donors in an intensive care unit (ICU are the richest source of organs for transplantation. Careful donor maintenance plays a vital role in the successful functioning of the organ in the recipient. Aims : Early identification of brain stem death (BSD in the ICU, problems and management in donor maintenance till retrieval are the main objectives. Materials and Methods : BSD was identified in a level I trauma center over a period of eight years (1996-2004 using UK code. After screening for fitness, they were maintained to achieve normothermia, systolic BP > 90 mm Hg, CVP 8-10 cm water, urine output > 80 ml/hour and normal acid base balance. Results: 168 cases of BSD were maintained, 30 with identity unknown. Common transient complications noted were hypotension (68%, hypokalemia (62%, hypothermia (12%, diabetes insipidus (70%. Brain stem death was identified early and resuscitated to maintain normal tissue perfusion. 17 (12.3% consent for organ donation was obtained. Organs (24 kidneys and one liver were retrieved from 12 donors. Four donors sustained cardiac arrest before retrieval. Conclusion: Early recognition of brain stem death and prompty correction of hemodyanamic instability is the key to deceased donor maintenance. Optimal care of potential donor translates to care of multiple recipients.

    2010-01-01

    Integrated operation and maintenance of process plants has many advantages. One advantage is the improved economy obtained by reducing the number of plant shutdowns. Another is to increase reliability of operation by monitoring of risk levels during on-line maintenance.

  7. Embracing Safe Ground Test Facility Operations and Maintenance

    Dunn, Steven C.; Green, Donald R.

    2010-01-01

    Conducting integrated operations and maintenance in wind tunnel ground test facilities requires a balance of meeting due dates, efficient operation, responsiveness to the test customer, data quality, effective maintenance (relating to readiness and reliability), and personnel and facility safety. Safety is non-negotiable, so the balance must be an "and" with other requirements and needs. Pressure to deliver services faster at increasing levels of quality in under-maintained facilities is typical. A challenge for management is to balance the "need for speed" with safety and quality. It s especially important to communicate this balance across the organization - workers, with a desire to perform, can be tempted to cut corners on defined processes to increase speed. Having a lean staff can extend the time required for pre-test preparations, so providing a safe work environment for facility personnel and providing good stewardship for expensive National capabilities can be put at risk by one well-intending person using at-risk behavior. This paper documents a specific, though typical, operational environment and cites management and worker safety initiatives and tools used to provide a safe work environment. Results are presented and clearly show that the work environment is a relatively safe one, though still not good enough to keep from preventing injury. So, the journey to a zero injury work environment - both in measured reality and in the minds of each employee - continues. The intent of this paper is to provide a benchmark for others with operational environments and stimulate additional sharing and discussion on having and keeping a safe work environment.

    2017-09-01

    The analysis of field operation and maintenance data collected during a period of over eight years, from CPV installations consisting of three different CPV technologies (including second generation of one of these technologies), has allowed us to get valuable information about the long-term degradation of the CPV systems. Through the study of the maintenance control ratio previously defined and by applying the root cause analysis methodology, the components responsible for the most unplanned interventions for each technology were identified. Focusing maintenance efforts on these components, a reduction of the unplanned interventions and the total cost of maintenance has been achieved over the years. Therefore, the deployment of an effective maintenance plan, identifying critical components, is essential to minimize the risk for investors and maximize the CPV power plants lifetime and energy output, increasing the availability of CPV installations, boosting market confidence in CPV systems.

  16. The Development and Deployment of a Maintenance Operations Safety Survey.

    Langer, Marie; Braithwaite, Graham R

    2016-11-01

    Based on the line operations safety audit (LOSA), two studies were conducted to develop and deploy an equivalent tool for aircraft maintenance: the maintenance operations safety survey (MOSS). Safety in aircraft maintenance is currently measured reactively, based on the number of audit findings, reportable events, incidents, or accidents. Proactive safety tools designed for monitoring routine operations, such as flight data monitoring and LOSA, have been developed predominantly for flight operations. In Study 1, development of MOSS, 12 test peer-to-peer observations were collected to investigate the practicalities of this approach. In Study 2, deployment of MOSS, seven expert observers collected 56 peer-to-peer observations of line maintenance checks at four stations. Narrative data were coded and analyzed according to the threat and error management (TEM) framework. In Study 1, a line check was identified as a suitable unit of observation. Communication and third-party data management were the key factors in gaining maintainer trust. Study 2 identified that on average, maintainers experienced 7.8 threats (operational complexities) and committed 2.5 errors per observation. The majority of threats and errors were inconsequential. Links between specific threats and errors leading to 36 undesired states were established. This research demonstrates that observations of routine maintenance operations are feasible. TEM-based results highlight successful management strategies that maintainers employ on a day-to-day basis. MOSS is a novel approach for safety data collection and analysis. It helps practitioners understand the nature of maintenance errors, promote an informed culture, and support safety management systems in the maintenance domain. © 2016, Human Factors and Ergonomics Society.

    operability of machine-tractor aggregates (MTA) is ensured by purposeful activity of maintenance and repair performers. MTAs operation assurance can provide achievement of absolutely different goals. For further development of technical service formation concept concretization in the part of determining locations of maintenance and repair performers and their area of expertise is suggested, as well as of arising peculiarities of equipment. The theoretical task is reduced to the type of tasks of distribution of recourses or transportation tasks. Mobile maintenance teams of regional agricultural equipment manufacturers’ dealers have experience of technical service performance. The formed stream of requests from agricultural plants determines the direction of correcting of existing theoretical provisions, confirming necessity of further development of centralized method of technical service by efforts and means of manufacturers’ dealers.

  20. Design of casks: incorporating operational feedback from maintenance

    Energy Technology Data Exchange (ETDEWEB)

    Bimet, F.; Hartenstein, M. [COGEMA Logistics, Saint Quentin (France)

    2004-07-01

    Casks are designed to conform to regulations and to client specifications. Essential areas such as easy operation, low costs of maintenance, low operation and maintenance doses, limited waste, are not explicitly covered. Notwithstanding, COGEMA LOGISTICS uses all feedback available, so that casks are designed to be easy, safe and economical to operate and maintain. Maintenance is an activity where you do spot items that old-time designers could have made better, and things that users should not have done. Thanks to quality assurance, there are a number of data available, waiting to be collected and exploited; they have to be identified, located, retrieved, and analysed. Using information such as wear, damage, use of spare parts, access problems helps to make casks ever better. It leads to more efficient concepts, and to upgrades on existing designs; it also allows to integrate environmental considerations, inter alia in the choice of materials and in maintenance methods. It is necessary for the designer to interact with the users, the cask owners, the maintenance providers, in order to gather all relevant information and events. This is made easier when all these actors are ''under one roof'', or have very close ties. This paper presents COGEMA LOGISTICS methods for collecting and analysing all these experiences waiting to be used. It explains our process for analysing data, preparing yearly reports that are made available to our designers. It describes how each new design is subject to a maintainability study, using this feedback, so that the cask safety is always assured, that radiological doses are kept to a minimum, and that operating and maintenance costs will remain as low as possible.

    The maintenance planning corresponds to an approach that seeks to maximize the availability of equipment and, consequently, increase the levels of competitiveness of companies by increasing production times. This paper presents a maintenance planning based on operating variables (number of hours worked, duty cycles, number of revolutions) to maximizing the availability of operation of electrical motors. The reading of the operating variables and its sampling is done based on predetermined sampling cycles and subsequently is made the data analysis through time series algorithms aiming to launch work orders before reaching the variables limit values. This approach is supported by tools and technologies such as logical applications that enable a graphical user interface for access to relevant information about their Physical Asset HMI (Human Machine Interface), including the control and supervision by acquisition through SCADA (Supervisory Control And data acquisition) data, also including the communication protocols among different logical applications.

    1995-01-01

    Maintenance operations incidents submitted to the Aviation Safety Reporting System (ASRS) between 1986-1992 were systematically analyzed in order to identify issues relevant to human factors and crew coordination. This exploratory analysis involved 95 ASRS reports which represented a wide range of maintenance incidents. The reports were coded and analyzed according to the type of error (e.g, wrong part, procedural error, non-procedural error), contributing factors (e.g., individual, within-team, cross-team, procedure, tools), result of the error (e.g., aircraft damage or not) as well as the operational impact (e.g., aircraft flown to destination, air return, delay at gate). The main findings indicate that procedural errors were most common (48.4%) and that individual and team actions contributed to the errors in more than 50% of the cases. As for operational results, most errors were either corrected after landing at the destination (51.6%) or required the flight crew to stop enroute (29.5%). Interactions among these variables are also discussed. This analysis is a first step toward developing a taxonomy of crew coordination problems in maintenance. By understanding what variables are important and how they are interrelated, we may develop intervention strategies that are better tailored to the human factor issues involved.

    2016-07-01

    The Atacama Large Millimeter/submillimeter Array (ALMA) is a joint project between astronomical organizations in Europe, North America, and East Asia, in collaboration with the Republic of Chile. ALMA consists of 54 twelve-meter antennas and 12 seven-meter antennas operating as an aperture synthesis array in the (sub)millimeter wavelength range. Since the inauguration of the observatory back in March 2013 there has been a continuous effort to establish solid operations processes for effective and efficient management of technical and administrative tasks on site. Here a key aspect had been the centralized maintenance and operations planning: input is collected from science stakeholders, the computerized maintenance management system (CMMS) and from the technical teams spread around the world, then this information is analyzed and consolidated based on the established maintenance strategy, the observatory long-term plan and the short-term priorities definitions. This paper presents the high-level process that has been developed for the planning and scheduling of planned- and unplanned maintenance tasks, and for site operations like the telescope array reconfiguration campaigns. We focus on the centralized planning approach by presenting its genesis, its current implementation for the observatory operations including related planning products, and we explore the necessary next steps in order to fully achieve a comprehensive centralized planning approach for ALMA in steady-state operations.

    The Electrical Exploitation is one of the few remaining operation services at CERN which nearly entirely relies on the CERN staff. Last year CERN policy, in connection with the LHC project needs, have led to the formulation of the strategy of out-sourcing of the Electrical Exploitation activities, market survey and subsequent Invitation to Tender. The following paper presents the approach used in the preparation of the Invitation to Tender and in solving of the out-sourcing issues applied to the operation and maintenance of the CERN electrical network. In particular the problems of the results oriented contract, quality assurance and performance as well requirement of the constantly increasing productivity of the Contractors team are treated. The paper gives also the particularities of the application of the out-sourcing to the electrical operation service as will as techniques used for the estimation of the work load of the activities being outsourced.

    The US Department of Energy (DOE), Office of Civilian Radioactive Waste Management (OCRWM) is responsible for the development of a waste management program for the disposition of spent nuclear fuel (SNF) and high-level waste (HLW). The program will include a transportation system for moving the nuclear waste from the sources to a geologic repository for permanent disposal. Specially designed casks will be used to safely transport the waste. The cask systems must be operated within limits imposed by DOE, the Nuclear Regulatory Commission (NRC), and the Department of Transportation (DOT). A dedicated facility for inspecting, testing, and maintaining the cask systems was recommended by the General Accounting Office (in 1979) as the best means of assuring their operational effectiveness and safety, as well as regulatory compliance. In November of 1987, OCRWM requested a feasibility study be made of a Cask Maintenance Facility (CMF) that would perform the required functions. 46 refs., 16 figs., 13 tabs.

    Parsons and LLNL scientists and engineers performed design and engineering work for power plant pre-conceptual designs based on the anticipated laser fusion demonstrations at the National Ignition Facility (NIF). Work included identifying concepts of operations and maintenance (O&M) and associated requirements relevant to fusion power plant systems analysis. A laser fusion power plant would incorporate a large process and power conversion facility with a laser system and fusion engine serving as the heat source, based in part on some of the systems and technologies advanced at NIF. Process operations would be similar in scope to those used in chemical, oil refinery, and nuclear waste processing facilities, while power conversion operations would be similar to those used in commercial thermal power plants. While some aspects of the tritium fuel cycle can be based on existing technologies, many aspects of a laser fusion power plant presents several important and unique O&M requirements that demand new solutions. For example, onsite recovery of tritium; unique remote material handling systems for use in areas with high radiation, radioactive materials, or high temperatures; a five-year fusion engine target chamber replacement cycle with other annual and multi-year cycles anticipated for major maintenance of other systems, structures, and components (SSC); and unique SSC for fusion target waste recycling streams. This paper describes fusion power plant O&M concepts and requirements, how O&M requirements could be met in design, and how basic organizational and planning issues can be addressed for a safe, reliable, economic, and feasible fusion power plant.

    Lake Billy Shaw is a newly constructed earthen dam reservoir with a surface area of 430 acres. Construction on the dam and structures was complete in November of 1998. The fish screen structures were complete in December of 1998, with initial filling in May 1999. Upon initial filling, dam structures, monitoring wells, fish screen structures, and lake level were monitored daily, with recordings being taken three times/week. During June 1999 the water to the lake was turned off in order to complete additional construction work on the lake. This work included installation of culverts around the perimeter road, installation of boat launches, finish work on the spillway structure, pumphouse and well protection and planting 4 trees along the entrance to the boat launch area. The water was turned on again in late September 1999 with all structures having been checked, fish screens greased and maintained and well levels being monitored. In 2000 the Operations and Maintenance portion of the project began with monitoring of piezometers, water levels, biological monitoring, riparian plantings, protection of shorelines, and maintenance of structures and appurtances.

    2014-07-01

    The importance of maintenance has escalated significantly by the increasing of automation in manufacturing process. This condition switches traditional maintenance perspective of inevitable cost into the business competitive driver. Consequently, maintenance strategy and operation decision needs to be synchronized to business and manufacturing concerns. This paper shows the development of conceptual design of Knowledge Based System for Integrated Maintenance Strategy and Operation (KBIMSO). The framework of KBIMSO is elaborated to show the process of how the KBIMSO works to reach the maintenance decision. By considering the multi-criteria of maintenance decision making, the KB system embedded with GAP and AHP to support integrated maintenance strategy and operation which is novel in this area. The KBIMSO is useful to review the existing maintenance system and give reasonable recommendation of maintenance decisions in respect to business and manufacturing perspective.

    With rising grid interconnections of solar photovoltaic (PV) systems, greater attention is being trained on lifecycle performance, reliability, and project economics. Expected to meet production thresholds over a 20-30 year timeframe, PV plants require a steady diet of operations and maintenance (O&M) oversight to meet contractual terms. However, industry best practices are only just beginning to emerge, and O&M budgets—given the arrangement of the solar project value chain—appear to vary widely. Based on insights from in-depth interviews and survey research, this paper presents an overview of the utility-scale PV O&M budgeting process along with guiding rationales, before detailing perspectives on current plant upkeep activities and price points largely in the U.S. It concludes by pondering potential opportunities for improving upon existing O&M budgeting approaches in ways that can benefit the industry at-large.

    2009-05-01

    The Special Purpose Dexterous Manipulator (SPDM), known as "Dextre", is currently slated to launch in February 2008 for deployment on the International Space Station (ISS) as the final component of Canada's Mobile Servicing System (MSS). Dextre's primary role on the Space Station is to perform repair and replacement (R&R) maintenance tasks on robotically compatible hardware such as Orbital Replaceable Units (ORUs), thereby eventually easing the burden on the ISS crew. This burden on the on-orbit crew translates practically into crew time being a limited resource on the ISS, and as such, finding ways to assist the crew in performing their tasks or offloading the crew completely when appropriate is a bonus to the ISS program. This is already accomplished very effectively by commanding as many non-critical robotics tasks as possible, such as powering up and free-space maneuvering of the Space Station Remote Manipulator System (SSRMS), known as "Canadarm2", from the Ground. Thus, beyond its primary role, and based on an increasing clarity regarding the challenges of external maintenance on the ISS, Dextre is being considered for use in a number of ways with the objective of improving ISS operations while reducing and optimizing the use of crew time through the use of ground control for various tasks, pre-positioning hardware, acting as a temporary storage platform to break an Extra Vehicular Activity (EVA) day into manageable timelines, and extending the physical reach and range of the Canadarm2. This paper discusses the planned activities and operations for Dextre an rationale for how these will help optimize the use of crew resources on the ISS.

    The Confederated Tribes of the Umatilla Indian Reservation (CTUIR) and Oregon Department of Fish and Wildlife (ODFW) are cooperating in a joint effort to enhance steelhead and re-establish salmon runs in the Umatilla River Basin. As an integral part of this program, Bonifer Pond, Minthorn Springs, Imeques C-mem-ini-kem and Thornhollow satellite facilities are operated for acclimation and release of juvenile summer steelhead (Oncorhynchus mykiss), fall and spring chinook salmon (O. tshawytscha) and coho salmon (O. kisutch). Minthorn is also used for holding and spawning adult summer steelhead and Three Mile Dam is used for holding and spawning adult fall chinook and coho salmon. Bonifer, Minthorn, Imeques and Thornhollow facilities are operated for acclimation and release of juvenile salmon and summer steelhead. The main goal of acclimation is to reduce stress from trucking prior to release and improve imprinting of juvenile salmonids in the Umatilla River Basin. Juveniles are transported to the acclimation facilities primarily from Umatilla and Bonneville Hatcheries. This report details activities associated with operation and maintenance of the Bonifer, Minthorn, Imeques, Thornhollow and Three Mile Dam facilities in 1996.

    Durability is one of the limiting factors for spreading and commercialization of fuel cell technology. That is why research to extend fuel cell durability is being conducted world wide. A pattern-recognition approach aiming to estimate fuel cell operating time based on electrochemical impedance spectroscopy measurements is presented here. It is based on extracting the features from the impedance spectra. For that purpose, two approaches have been investigated. In the first one, particular points of the spectrum are empirically extracted as features. In the second approach, a parametric modeling is performed to extract features from both the real and the imaginary parts of the impedance spectrum. In particular, a latent regression model is used to automatically split the spectrum into several segments that are approximated by polynomials. The number of segments is adjusted taking into account the a priori knowledge about the physical behavior of the fuel cell components. Then, a linear regression model using different subsets of extracted features is employed for an estimate of the fuel cell operating time. The effectiveness of the proposed approach is evaluated on an experimental dataset. Allowing the estimation of the fuel cell operating time, and consequently its remaining duration life, these results could lead to interesting perspectives for predictive fuel cells maintenance policy.

    Full Text Available Abstract. Market globalization, competitive product and services, high economic crises are the most critical factors that influence the success of the manufacturing companies in global market. Therefore it is critical to the manufacturing companies to be efficient in production and lean tool may used to achieve that.  The most frequently used is the Total Preventive Maintenance (TPM, even though there are many studies have been conducted in relation to the TPM but there is limited research in investigating the effects of the TPM on operational performance. However, the result of the studies was not consistent, where TPM practice may have positive and negative impact on operational performance. Among the reason is the culture of the organization that influenced the implementation of TPM and operational performance. Due to that this study attempts to investigate the influence of organizational culture on the TPM implementation and operational performance.  Rasch model is used in this study due to its ability in interpreting and analyzing the ability of respondents in performing the difficult items. The online questionnaires were distributed to 63 randomly selected automotive companies located at Northern Region of Malaysia.  Results of the study revealed that the organizational culture has influenced on the successful implementation of TPM and operational performance. Therefore by the implementation of TPM in outstanding organizational culture can improve operational performance.   Keyword: Total Preventive Maintenance (TPM, Lean manufacturing, Operational performance, Organizational culture, Rasch modeldoi:10.12695/ajtm.2013.6.2.2How to cite this article:Mohd Asaad, M.N and Yusoff, R.Z.

    We examine scale and scope economics among Group and IPA Health Maintenance Organizations (HMOs) over the period 1988 to 1991 using a national sample of HMOs. We allow for the multiproduct nature of HMO production by estimating the cost of producing a member month of non-Medicare and Medicare coverage, and we examine the effect of HMO market structure on costs. We find that HMOs benefit from scale economies. There are scope diseconomies associated with providing both non-Medicare and Medicare products. Group HMOs in more competitive markets have lower costs but IPA costs are not affected by competition.

  12. Industrial operations and maintenance energy measures: A review

    Energy Technology Data Exchange (ETDEWEB)

    Parker, S.A.; Gaustad, K.L.; Winiarski, D.W.

    1994-12-01

    Industry consumes a significant percentage of the total electric energy consumption both nationally and in the Pacific Northwest. However, industrial demand-side management (DSM) activities in this sector are underdeveloped and typically concentrate on new technologies and new equipment. An overlooked opportunity for electric resource development is through operations and maintenance (O and M) activities. The purpose of this project is to determine the industrial DSM potential that may be achieved through O and M practices both in the US and the Pacific Northwest. The overall goal of the project is to identify, quantify, confirm, and develop conservation resources that can be achieved from the industrial sector through O and M practices and energy measures. The results of the study identify a significant electric resource potential available through improved O and M activities in industry. Several O and M type energy-saving measures that increase efficiencies and reduce loads are identified and estimates of potential energy savings associated with each measure are presented. Systems identified with the most potential include compressed-air systems; motors and motor drives; lighting; heating, ventilating and air conditioning (HVAC); and control systems. The results of the research show that industrial electric energy consumption can be notably reduced by implementing key O and M type energy measures. Specifically, the results of industrial energy audits, case studies, and other published sources indicate that reductions in energy consumption from improved O and M activities can average between 8% and 12.5%.

    Sullivan, Greg; Pugh, Ray; Melendez, Aldo P.; Hunt, W. D.

    2010-08-04

    This guide highlights operations and maintenance programs targeting energy and water efficiency that are estimated to save 5% to 20% on energy bills without a significant capital investment. The purpose of this guide is to provide you, the Operations and Maintenance (O&M)/Energy manager and practitioner, with useful information about O&M management, technologies, energy and water efficiency, and cost-reduction approaches. To make this guide useful and to reflect your needs and concerns, the authors met with O&M and Energy managers via Federal Energy Management Program (FEMP) workshops. In addition, the authors conducted extensive literature searches and contacted numerous vendors and industry experts. The information and case studies that appear in this guide resulted from these activities. It needs to be stated at the outset that this guide is designed to provide information on effective O&M as it applies to systems and equipment typically found at Federal facilities. This guide is not designed to provide the reader with step-by-step procedures for performing O&M on any specific piece of equipment. Rather, this guide first directs the user to the manufacturer's specifications and recommendations. In no way should the recommendations in this guide be used in place of manufacturer's recommendations. The recommendations in this guide are designed to supplement those of the manufacturer, or, as is all too often the case, provide guidance for systems and equipment for which all technical documentation has been lost. As a rule, this guide will first defer to the manufacturer's recommendations on equipment operation and maintenance.

  2. Assessment of Operational Maintenance in Public Hospitals Buildings in the Gaza Strip

    Full Text Available The issue of public hospitals buildings’ maintenance in Palestine is regarded as a challenging issue. The lack of attention to maintenance management in hospitals has led to deterioration of buildings and reduced the health care services. The aim of this paper is to assess the current practice of maintenance process and management in public hospitals buildings in the Gaza Strip. A questionnaire survey that distributed to 13 public hospitals, which are administered by the Ministry of Health (MoH in the Gaza Strip, was used to collect the primary data for this study. The results of this study present an overview of the current situation of the maintenance process in public hospitals buildings in the Gaza Strip. The findings indicated that while the corrective maintenance is implemented in all the 13 public hospitals, preventive maintenance is employed along with corrective maintenance, only in three hospitals. In addition, the findings indicated variances in responding to maintenance requests, while 50% of the maintenance departments took few hours to respond to maintenance requests, the rest took a few days to respond, this can be explained due to lack of spare parts and qualified staff. The study showed also that there is a shortage in training the hospital facility’s users on how to report maintenance problems. The results of this study indicated that most hospitals in the Gaza Strip have no maintenance plan for medical equipment; they do not have quality control system for repair and preventive maintenance. It is recommended to employ experience maintenance staff in order to prepare adequate maintenance plan and detailed check list, which is required for preventive maintenance. The MoH should organize specialized training courses in maintenance management for their staff in order to improve their effectiveness and efficiency. Hospitals in Gaza should make sure that all spare parts available in their storages for immediate action when

    This paper aims at presenting a method to optimize the maintenance planning for a commercial heavy vehicle. Such a vehicle may be considered as a multi-components system. Grouping maintenance operations related to each component reduces the global maintenance cost of the system. Classically, the optimization problem is solved using a priori reliability characteristics of components. Two types of methods may be used, i.e. static or dynamic methods. Static methods provide a fixed maintenance planning, whereas dynamic methods redefine the groups of maintenance operations at each decision time. Dynamic procedures can incorporate component information such as component states or detected failures. For deteriorating systems, reliability characteristics of each component may be estimated thanks to deterioration models and may be updated when a degradation measure is available. This additional information on degradation features allows to better follow the real state of each component and to improve the maintenance planning.

  7. Value centric approaches to the design, operations and maintenance of wind turbines

    Science.gov (United States)

    Khadabadi, Madhur Aravind

    Wind turbine maintenance is emerging as an unexpectedly high component of turbine operating cost, and there is an increasing interest in managing this cost. This thesis presents an alternative view of maintenance as a value-driver, and develops an optimization algorithm to evaluate the value delivered by different maintenance techniques. I view maintenance as an operation that moves the turbine to an improved state in which it can generate more power and, thus, earn more revenue. To implement this approach, I model the stochastic deterioration of the turbine in two dimensions: the deterioration rate, and the extent of deterioration, and then use maintenance to improve the state of the turbine. The value of the turbine is the difference between the revenue from to the power generation and the costs incurred in operation and maintenance. With a focus on blade deterioration, I evaluate the value delivered by implementing two different maintenance schemes, predictive maintenance and scheduled maintenance. An example of predictive maintenance technique is the use of Condition Monitoring Systems to precisely detect deterioration. I model Condition Monitoring System (CMS) of different degrees of fidelity, where a higher fidelity CMS would allow the blade state to be determined with a higher precision. The same model is then applied for the scheduled maintenance technique. The improved state information obtained from these techniques is then used to derive an optimal maintenance strategy. The difference between the value of the turbine with and without the inspection type can be interpreted as the value of the inspection. The results indicate that a higher fidelity (and more expensive) inspection method does not necessarily yield the highest value, and, that there is an optimal level of fidelity that results in maximum value. The results also aim to inform the operator of the impact of regional parameters such as wind speed, variance and maintenance costs to the optimal

  13. Modeling and Simulation of HVAC Faulty Operations and Performance Degradation due to Maintenance Issues

    Energy Technology Data Exchange (ETDEWEB)

    2013-01-01

    Almost half of the total energy used in the U.S. buildings is consumed by heating, ventilation and air conditionings (HVAC) according to EIA statistics. Among various driving factors to energy performance of building, operations and maintenance play a significant role. Many researches have been done to look at design efficiencies and operational controls for improving energy performance of buildings, but very few study the impacts of HVAC systems maintenance. Different practices of HVAC system maintenance can result in substantial differences in building energy use. If a piece of HVAC equipment is not well maintained, its performance will degrade. If sensors used for control purpose are not calibrated, not only building energy usage could be dramatically increased, but also mechanical systems may not be able to satisfy indoor thermal comfort. Properly maintained HVAC systems can operate efficiently, improve occupant comfort, and prolong equipment service life. In the paper, maintenance practices for HVAC systems are presented based on literature reviews and discussions with HVAC engineers, building operators, facility managers, and commissioning agents. We categorize the maintenance practices into three levels depending on the maintenance effort and coverage: 1) proactive, performance-monitored maintenance; 2) preventive, scheduled maintenance; and 3) reactive, unplanned or no maintenance. A sampled list of maintenance issues, including cooling tower fouling, boiler/chiller fouling, refrigerant over or under charge, temperature sensor offset, outdoor air damper leakage, outdoor air screen blockage, outdoor air damper stuck at fully open position, and dirty filters are investigated in this study using field survey data and detailed simulation models. The energy impacts of both individual maintenance issue and combined scenarios for an office building with central VAV systems and central plant were evaluated by EnergyPlus simulations using three approaches: 1) direct

  19. Pricing health care services: applications to the health maintenance organization.

    Science.gov (United States)

    Sweeney, R E; Franklin, S P

    1986-01-01

    This article illustrates how management in one type of service industry, the health maintenance organization (HMO), have attempted to formalize pricing. This effort is complicated by both the intangibility of the service delivered and the relatively greater influence in service industries of non-cost price factors such as accessibility, psychology, and delays. The presentation describes a simple computerized approach that allows the marketing manager to formally estimate the effect of incremental changes in rates on the firm's projected patterns of enrollment growth and net revenues. The changes in turn reflect underlying variations in the mix of pricing influences including psychological and other factors. Enrollment projections are crucial to the firm's financial planning and staffing. In the past, most HMO enrollment and revenue projections of this kind were notoriously unreliable. The approach described here makes it possible for HMOs to fine-tune their pricing policies. It also provides a formal and easily understood mechanism by which management can evaluate and reach consensus on alternative scenarios for enrollment growth, staff recruitment and capacity expansion.

    2003-07-01

    In response to growing demands from the Norwegian oil and gas industry, a joint industry project on the development and implementation of operations and maintenance performance indicators for the petroleum industry was initiated by the Center for Asset and Maintenance Management of Stavanger University College, Norway, in 1999. The project consortium composed of BP, Shell, Philips, Statoil, NorskHydro, Norwegian Petroleum Directorate, PricewaterhouseCoopers, Andersen Consulting, DNV, Industrial and Financial Systems (IFS), ADB Systems AS, DNV, RC Consultants and Tieto Enator. While the project was managed effectively to serve the expectations of member organizations, its boundaries were predefined by various conditions within organizational environments leaving a substantial space unexplored. Hence, the width and the breadth of operations and maintenance performance captured by the project were largely limited. This called for an independent research study to explore the phenomenon with a more broader or holistic perspective. Notably thus, while the project was devoted to a down-to-earth component of the exercise, i.e. to develop performance indicators, the exploratory research study was launched alongside to bring a theoretical or a philosophical insight. The study was conducted during 2000-2002 with collaboration of 14 organizations within the Norwegian continental shelf. The population included oil and gas producers regulatory and verification bodies and third parties. The study identified the bulk of problems that the entire problem domain constitute of within operations and maintenance performance. They were classified into some theoretical forms, and the study concentrated on, what I term, technical alienation, i.e. lack of descriptive performance models to guide meaningful assessment and management of operations and maintenance performance. The choice to shed some light in this endeavor was based on the relevance to SDV project, emerging managerial interest

  7. THE EFFECTS OF MAINTENANCE ACTIONS ON THE PFDavg OF SPRING OPERATED PRESSURE RELIEF VALVES

    Energy Technology Data Exchange (ETDEWEB)

    Harris, S.; Gross, R.

    2014-04-01

    The safety integrity level (SIL) of equipment used in safety instrumented functions is determined by the average probability of failure on demand (PFDavg) computed at the time of periodic inspection and maintenance, i.e., the time of proof testing. The computation of PFDavg is generally based solely on predictions or estimates of the assumed constant failure rate of the equipment. However, PFDavg is also affected by maintenance actions (or lack thereof) taken by the end user. This paper shows how maintenance actions can affect the PFDavg of spring operated pressure relief valves (SOPRV) and how these maintenance actions may be accounted for in the computation of the PFDavg metric. The method provides a means for quantifying the effects of changes in maintenance practices and shows how these changes impact plant safety.

    In response to concerns about the potential hazard of Mauna Loa volcano in Hawaii, the USGS began efforts in 1998 to add four high-resolution borehole sites. Located at these sites are; strainmeters, tiltmeters, seismometers, accelerometers and other instrumentation. These instruments are capable of providing continuous monitoring of the magma movement under Mauna Loa. Each site was planned to provide multi-parameter monitoring of volcanic activity. In June of 2000, a contract was let for the core drilling of three of these four sites. They are located at Hokukano (west side of Mauna Loa) above Captain Cook, Hawaii; at Mauna Loa Observatory (11,737 feet near the summit), and at Mauna Loa Strip Road (east side of Mauna Loa). Another site was chosen near Halema'uma u' and Kilauea's summit, in the Keller deep well. (See maps). The locations of these instruments are shown in Figure 1 with their latitude and longitude in Table 1. The purpose of this network is to monitor crustal deformation associated with volcanic intrusions and earthquakes on Mauna Loa and Kilauea volcanoes. This report describes the methods used to locate sites, install dilatometers, other instrumentation, and telemetry. We also provide a detailed description of the electronics used for signal amplification and telemetry, plus techniques used for instrument maintenance. Instrument sites were selected in regions of hard volcanic rock where the expected signals from magmatic activity were calculated to be a maximum and the probability of earthquakes with magnitude 4 or greater is large. At each location, an attempt was made to separate tectonic and volcanic signals from known noise sources for each instrument type.

The SW3 facility has been designated Solid Waste Management Unit (SWMU) 088 under KSC's Resource Conservation and Recovery Act (RCRA) Corrective Action Program. Based on the results to date, the SW3 air sparging (AS) system is operating at or below the performance criteria as presented in the 2008 SW3 Corrective Measures Implementation (CMI) Work Plan and 2009 and 2012 CMI Work Plan Addenda. Since the start of AS system operations on December 19, 2012, through the September 2016 groundwater sampling event, TCE concentrations have decreased to less than the GCTL in all wells within the Active Remediation Zone (ARZ), and VC results remain less than NADC but greater than GCTL. Based on these results, team consensus was reached at the October 2016 KSC Remediation Team (KSCRT) meeting to continue AS system operations and semi-annual performance monitoring of volatile organic compounds in March 2017 at ten monitoring wells at select locations, and in September 2017 at four monitoring wells at select locations to reduce VC concentrations to below GCTL. Additionally, surface water samples

    The National Radiobiology Archives (NRA) are an archival program, started in 1989, to collect, organize and maintain data, laboratory notebooks, and animal tissue specimens from government (Department of Energy and its predecessor agencies) sponsored radiobiology life-span animal studies. These unique records, histopathology slides and paraffin embedded tissue blocks are maintained in a central facility and are available for further research study. The materials include electronic and paper records for each of more than 6,000 life-span-observations on dogs as well as details of major studies involving nearly 30,000 mice. Although these studies were performed over many years and at different laboratories with differing data management systems, the NRA has translated them into a standardized set of relational database tables. These can be distributed to interested individuals on written request. Specific Aims are: (1) To Maintain the Archive of Written Records from the Animal Experiments - The USTUR continued to maintain the NRA archives which consist of approximately 175 storage boxes containing laboratory notebooks, animal exposure records, animal pathologic records, and radiographs. These were stored in a 6,000 square foot leased facility in Richland, WA. Additionally, through a collaboration with Pacific Northwest National Laboratory's (PNNL) Low Dose Program, many of these records were scanned into digital files. These totaled 34 GB of data, which are saved in 2,407 separate PDF files that are organized by box number and animal identification number. (2) To Maintain the Archive of Animal Tissues at Washington State University - The USTUR continued to house the NRA dog tissue collection in the leased facility. The NRA tissue collection consisted of pathology slides and tissue blocks. Approximately 25% of the laboratory facility was dedicated to the storage of the NRA materials. (3) To Organize the Datasets of These Animals in the Context of Other Datasets so

    The Confederated Tribes of the Umatilla Indian Reservoir (CTUIR) and Oregon Department of Fish and Wildlife (ODFW) are cooperating in a joint effort to enhance steelhead and re-establish salmon runs in the Umatilla River Basin. As an integral part of this program, Bonifer Pond, Minthorn Springs, Imeques C-mem-ini-kem and Thornhollow facilities are operated for acclimation and release of juvenile summer steelhead (Oncorhynchus mykiss), fall and spring chinook salmon (O. tshawytscha) and coho salmon (O. kisutch). Minthorn is also used for holding and spawning adult summer steelhead, fall chinook and coho salmon. Personnel from the ODFW Eastern Oregon Fish Pathology Laboratory in La Grande took samples of tissues and reproductive fluids from Umatilla River summer steelhead and coho salmon broodstock for monitoring and evaluation purposes. Coded-wire tag recovery information was accessed to determine the contribution of Umatilla river releases to ocean, Columbia River and Umatilla River fisheries.

    As part of its required activities in 1994, the US Department of Energy (DOE) made over 500,000 shipments. Of these shipments, approximately 4% were hazardous, and of these, slightly over 1% (over 6,400 shipments) were radioactive. Because of DOE`s cleanup activities, the total quantities and percentages of radioactive material (RAM) that must be moved from one site to another is expected to increase in the coming years, and these materials are likely to be different than those shipped in the past. Irradiated fuel will certainly be part of the mix as will RAM samples and waste. However, in many cases these materials will be of different shape and size and require a transport packaging having different shielding, thermal, and criticality avoidance characteristics than are currently available. This Handbook provides guidance on the design, testing, certification, and operation of packages for these materials.

    2016-09-01

    The combination of maintenance planning and key performance indicators are relevant to create a more holistic scenario of the mining activities. On the one hand, reliability and maintainability are system characteristics suitable for planning maintenance strategies. On the other hand, key performance indicators are suitable to analyze cost and resource consumption information about mining equipment. Nevertheless in practice, both approaches are modeled separately and frequently by different team-works of a mining company. With this in mind, a computer-aided application was conceived to drive with better efficacy the operational and maintenance strategy in a complex process where the equipment is in continuous movement such as the transportation process in an open-mine pit.

    Carnero, María Carmen; Gómez, Andrés

    2016-04-23

    Healthcare organizations have far greater maintenance needs for their medical equipment than other organization, as many are used directly with patients. However, the literature on asset management in healthcare organizations is very limited. The aim of this research is to provide more rational application of maintenance policies, leading to an increase in quality of care. This article describes a multicriteria decision-making approach which integrates Markov chains with the multicriteria Measuring Attractiveness by a Categorical Based Evaluation Technique (MACBETH), to facilitate the best choice of combination of maintenance policies by using the judgements of a multi-disciplinary decision group. The proposed approach takes into account the level of acceptance that a given alternative would have among professionals. It also takes into account criteria related to cost, quality of care and impact of care cover. This multicriteria approach is applied to four dialysis subsystems: patients infected with hepatitis C, infected with hepatitis B, acute and chronic; in all cases, the maintenance strategy obtained consists of applying corrective and preventive maintenance plus two reserve machines. The added value in decision-making practices from this research comes from: (i) integrating the use of Markov chains to obtain the alternatives to be assessed by a multicriteria methodology; (ii) proposing the use of MACBETH to make rational decisions on asset management in healthcare organizations; (iii) applying the multicriteria approach to select a set or combination of maintenance policies in four dialysis subsystems of a health care organization. In the multicriteria decision making approach proposed, economic criteria have been used, related to the quality of care which is desired for patients (availability), and the acceptance that each alternative would have considering the maintenance and healthcare resources which exist in the organization, with the inclusion of a

  15. Wind Turbine Blade Life-Time Assessment Model for Preventive Planning of Operation and Maintenance

    Directory of Open Access Journals (Sweden)

    Mihai Florian

    2015-09-01

    Full Text Available Out of the total wind turbine failure events, blade damage accounts for a substantial part, with some studies estimating it at around 23%. Current operation and maintenance (O&M practices typically make use of corrective type maintenance as the basic approach, implying high costs for repair and replacement activities as well as large revenue losses, mainly in the case of offshore wind farms. The recent development and evolution of condition monitoring techniques, as well as the fact that an increasing number of installed turbines are equipped with online monitoring systems, offers a large amount of information on the blades structural health to the decision maker. Further, inspections of the blades are often performed in connection with service. In light of the obtained information, a preventive type of maintenance becomes feasible, with the potential of predicting the blades remaining life to support O&M decisions for avoiding major failure events. The present paper presents a fracture mechanics based model for estimating the remaining life of a wind turbine blade, focusing on the crack propagation in the blades adhesive joints. A generic crack propagation model is built in Matlab based on a Paris law approach. The model is used within a risk-based maintenance decision framework to optimize maintenance planning for the blades lifetime.

    Needs for improved tools for nuclear power plant maintenance preparation are expressed by EDF engineering. These are an easier and better management of logistics constraints such as free spaces for motions or handling tasks. The lack of generic or well suited tools and the specificity of nuclear maintenance operation have led EDF R and D to develop its own motion planning tools in collaboration with LAAS-CNRS, Utrecht University and the software publisher CADCENTRE within the framework of the three years Esprit LTR project MOLOG. EDF users needs will be summed up in the first part of the paper under the title ''Motion feasibility studies for maintenance operation'' and then compared to the current industrial offer in the ''Software's background'''s part. The definition and objectives ''Towards motion planning tools'' follows. It explains why maintenance preparation pertains to automatic motion planning and how it makes studies much simpler. The ''MOLOG's Benchmark and first result'''s part describes the test-case used to evaluate the MOLOG project and gives an outlook at the results obtained so far. (author)

    2009-12-01

    Full Text Available The goal of Lean TPM or TPM for lean organization approach is maintaining international competitiveness . This Lean TPM from our article, approach proposes tree additions to the current understanding of the TPM system: the 7Ss as a critical first step in any improvement program; instant maintenance; improvement setup operations. A company cannot make business gains solely by using cost-cutting measures because it cannot cost enough to become a world-class competitor. Instead, it must invest resources in productivity improvement. This generally increases factory throughput and cuts costs at the same time. Maintaining equipment in its optimal state and continually improving its productivity is the whole strategy behind TPM. The main objective of the 7S system is to grow the value added to each worker. To grow the added value, we must create ordered and well adjusted production lines based on the principles of the 7S’s: organization and order. Above all these two S’s bring to the factory standard positions and acknowledgement. Focus on the first two S’s brings a new perspective on understanding the 7S’s.

    Operation and maintenance are significant contributors to the cost of energy for offshore wind turbines. Optimal planning could rationally be based on Bayesian pre-posterior decision theory, and all costs through the lifetime of the structures should be included. This paper contains a study...... of a generic case where the costs are evaluated for a single wind turbine with a single component. Costs due to inspections, repairs, and lost production are included in the model. The costs are compared for two distinct maintenance strategies, namely with and without inclusion of periodic imperfect...... inspections. Finally the influence of different important parameters, e.g. failure rate, reliability of inspections, inspection interval, and decision rule for repairs, is evaluated....

The compensated waveforms yield to a robust estimation of Lamb waves difference in distance of propagation (DDOP, used to feed hyperbolic algorithms for impact location determination, and allow an estimation of the uncertainty of the impact positioning as well as of the impact energy. The outputs of the impact methodology are passed to a visualization technology that yielding their representation in Augmented Reality (AR is meant to support the inspector during the on-field inspection/diagnosis as well as the maintenance operations. The inspector, in fact, can see interactively in real time the impact data directly on the surface of the structure. To validate the proposed approach, tests on an aluminum plate are presented. Results confirm the feasibility of the method and its exploitability in maintenance practice.

    Individuals seeking weight loss treatment endorse unrealistic expectations regarding their goals for weight loss, although these conclusions are primarily based on research conducted in obesity specialty clinics and/or controlled clinical trials. This study examined the weight loss goals and predictors of these goals among patients participating in obesity treatment in an applied, clinical setting (i.e., managed care organization). Managed care patients enrolled in a behavioral weight loss program (N=143; mean age=46.8 years; mean BMI=36.9 kg/m(2); 89.5% female; 64.5% Caucasian) completed a self-report survey during an initial weight loss session. The survey included items assessing patients' weight loss expectations, including goals for dream, happy, acceptable, and disappointed weights. Participants completed questions regarding contacts with their primary care physician and physician provision of weight loss counseling and/or referrals. They also provided values for current height and weight. BMI's and weight loss associated with dream, happy, acceptable, and disappointed weight goals were 24.8 kg/m(2) (30.9% loss), 27.1 kg/m(2) (25.2% loss), 29.3 kg/m(2) (19.7% loss), and 33.0 kg/m(2) (10.4% loss), respectively. There were significant gender differences in weight loss goals, with women endorsing more unrealistic goals than men for dream and happy weights, ps<0.001. Significant predictors of all four weight loss goals included baseline BMI, gender, ethnicity, and frequency of visits with one's primary care physician, ps<0.01. Consistent with previous research, patients participating in a weight loss program implemented in a managed care setting endorsed unrealistic expectations for weight loss. However, more frequent contact with one's primary care physician was associated with more realistic goals. Future, longitudinal research is needed to document the discrepancy between these goals and actual weight loss achieved in such settings as well as to determine

    The Duck Valley Reservoirs Fish Stocking and Operations and Maintenance (DV Fisheries) project is an ongoing resident fish program that serves to partially mitigate the loss of anadromous fish that resulted from downstream construction of the hydropower system. The project's goals are to enhance subsistence fishing and educational opportunities for Tribal members of the Shoshone-Paiute Tribes and provide resident fishing opportunities for non-Tribal members. In addition to stocking rainbow trout (Oncorhynchus mykiss) in Mountain View, Lake Billy Shaw, and Sheep Creek Reservoirs, the program is also designed to maintain healthy aquatic conditions for fish growth and survival, to provide superior facilities with wilderness qualities to attract non-Tribal angler use, and to offer clear, consistent communication with the Tribal community about this project as well as outreach and education within the region and the local community. Tasks for this performance period are divided into operations and maintenance plus monitoring and evaluation. Operation and maintenance of the three reservoirs include fences, roads, dams and all reservoir structures, feeder canals, water troughs and stock ponds, educational signs, vehicles and equipment, and outhouses. Monitoring and evaluation activities included creel, gillnet, wildlife, and bird surveys, water quality and reservoir structures monitoring, native vegetation planting, photo point documentation, control of encroaching exotic vegetation, and community outreach and education. The three reservoirs are monitored in terms of water quality and fishery success. Sheep Creek Reservoir was very unproductive this year as a fishery. Fish morphometric and water quality data indicate that the turbidity is severely impacting trout survival. Lake Billy Shaw was very productive as a fishery and received good ratings from anglers. Mountain View was also productive and anglers reported a high number of quality sized fish. Water quality

    The Duck Valley Reservoirs Fish Stocking and Operations and Maintenance (DV Fisheries) project is an ongoing resident fish program designed to enhance both subsistence fishing, educational opportunities for Tribal members of the Shoshone-Paiute Tribes, and recreational fishing facilities for non-Tribal members. In addition to stocking rainbow trout (Oncorhynchus mykiss) in Mountain View, Lake Billy Shaw, and Sheep Creek Reservoirs, the program also intends to afford and maintain healthy aquatic conditions for fish growth and survival, to provide superior facilities with wilderness qualities to attract non-Tribal angler use, and to offer clear, consistent communication with the Tribal community about this project as well as outreach and education within the region and the local community. Tasks for this performance period are divided into operations and maintenance plus monitoring and evaluation. Operation and maintenance of the three reservoirs include fences, roads, dams and all reservoir structures, feeder canals, water troughs and stock ponds, educational signs, vehicles and equipment, and outhouses. Monitoring and evaluation activities included creel, gillnet, wildlife, and bird surveys, water quality and reservoir structures monitoring, native vegetation planting, photo point documentation, control of encroaching exotic vegetation, and community outreach and education. The three reservoirs are monitored in terms of water quality and fishery success. Sheep Creek Reservoir was the least productive as a result of high turbidity levels and constraining water quality parameters. Lake Billy Shaw trout were in poorer condition than in previous years potentially as a result of water quality or other factors. Mountain View Reservoir trout exhibit the best health of the three reservoirs and was the only reservoir to receive constant flows of water.

    Slovensky plynarensky priemysel (SPP) has operated 17 487 km of gas pipelines in 1995. The length of the long-line pipelines reached 5 191 km, distribution network was 12 296 km. The international transit system of long-line gas pipelines ranged 1 939 km of pipelines of various dimensions. The described scale of transport and distribution system represents a multibillion investments stored in the ground, which are exposed to the environmental influences and to pipeline operational stresses. In spite of all technical and maintenance arrangements, which have to be performed upon operating gas pipelines, the gradual ageing takes place anyway, expressed in degradation process both in steel tube, as well as in the anti-corrosion coating. Within a certain time horizon, a consistent and regular application of methods and means of in-service technical diagnostics and rehabilitation of existing pipeline systems make it possible to save substantial investment funds, postponing the need in funds for a complex or partial reconstruction or a new construction of a specific gas section. The purpose of this presentation is to report on the implementation of the programme of in-service technical diagnostics of gas pipelines within the framework of regular maintenance of SPP s.p.

    Systems and structures related to HANARO safety are classified as seismic category I. Since 1995, the seismic monitoring system has been utilized for monitoring an earthquake at the HANARO site. The existing seismic monitoring system consists of field sensors and monitoring panel. The analog-type monitoring system with magnetic tape recorder is out-of-date model. In addition, the disadvantage of the existing system is that it does not include signal-analyzing equipment. Therefore, we have improved the analog seismic monitoring system into a new digital Seismic Monitoring Analysis System(SMAS) that can offer precise and detail information of the earthquake signals. This newly developed SMAS is operating at the HANARO instrument room to acquire and analyze the signal of an earthquake. This document is a guidebook for the operation and maintenance of the SMAS. The first chapter gives an outline of the SMAS. The second chapter describes functional capability and specification of the hardware. Chapters 3 and 4 describe starting procedure of the SMAS and how to operate the seismic monitoring program, respectively. Chapter 5 illustrates the seismic analysis algorithm used in the SMAS. The way of operating the seismic analysis program is described in chapter 6. Chapter 7 illustrates the calibration procedure for data acquisition module. Chapter 8 describes the symptoms of common malfunctions and its countermeasure suited to the occasions.

    Fact sheet summarizing technical report TP-7A40-67553. As solar photovoltaic (PV) systems have continued their transition from niche applications into large, mature markets in the United States, their potential as financial investments has risen accordingly. Mainstream investors, however, need to feel confident about the risk and return of solar photovoltaic (PV) systems before committing funds. A major influence on risk and return for PV is operations and maintenance (O&M) - but O&M practices and costs vary widely across the United States, making these variables difficult for investors to predict. To address this barrier to continued PV investment, the PV O&M Working Group has developed a new best-practices guide for PV O&M.

    1999-12-01

    The increased use of natural-gas-fuelled combined cycle gas turbine and combined heat and power plants in recent years has been accompanied by the practice of constructing acoustic enclosures around the gas turbines for environmental reasons. This can increase the risk of an explosion if, for any reason, there is a build-up of flammable gas within the enclosure, since there can be a range of possible ignition sources. The UK Health and Safety Executive consider gas leaks within such enclosures to be foreseeable, especially following maintenance. The paper presents a review of operational safety and a leak detection method for the inspection and design of flanged joints within the acoustic enclosures around GE 9001FA gas turbines, providing a practical step towards minimising the risk of explosion due to fuel leakage.

The BPS consists of 13,728 batteries, interconnecting buswork, and a power conditioning inductor. The system is subdivided into six modules, each divided into six gangs with its own gang switch, each gang containing 24 battery strings. Each module has its own main bus pair, with the negative bus common and the positive bus switched. The operational and performance history of the AFATL BPS has proven that this battery system is effective as a prime power supply for hypervelocity launcher research. Turn-around time between tests has generally been less than that required for the test article. The power capabilities of the BPS can easily be expanded to the design point of a 200 MJ energy store. This can be done by adding more modules of batteries and reconfiguring the inductor with its existing three auxiliary turns in series.

  2. On the Analysis of a Wave Energy Farm with Focus on Maintenance Operations

    Full Text Available Wave energy has a promising technical potential that could contribute to the future energy mix. However, costs related to the deployment of wave energy converters (WECs are still high compared to other technologies. In order to reduce these costs, two principle options are available, a reduction in cost and an increase in productivity. This paper presents a reliability-based computational tool to identify typical decision problems and to shed light on the complexity of optimising a wave power farm. The proposed tool is used to investigate productivity and availability of a wave energy farm during 10 years of operational life. A number of optimization possibilities to improve productivity, namely vessel choice, maintenance regime, failure rate and component redundancy, are then explored in order to assess their effectiveness. The paper quantifies the yield increase and provides a practical approach to evaluate the effectiveness of strategic and operational decision options. Results, in terms of the variations in productivity and availability of the farm, are analysed and discussed. Conclusions highlight the importance of reliability-centred simulations that consider the specific decision parameters throughout the operational life to find suitable solutions that increase the productivity and reduce the running cost for offshore farms.

    This report describes the results of a six-year, $6.3 million project to reduce operation and maintenance (O&M) costs at power plants employing concentrating solar power (CSP) technology. Sandia National Laboratories teamed with KJC Operating Company to implement the O&M Improvement Program. O&M technologies developed during the course of the program were demonstrated at the 150-MW Kramer Junction solar power park located in Boron, California. Improvements were made in the following areas: (a) efficiency of solar energy collection, (b) O&M information management, (c) reliability of solar field flow loop hardware, (d) plant operating strategy, and (e) cost reduction associated with environmental issues. A 37% reduction in annual O&M costs was achieved. Based on the lessons learned, an optimum solar- field O&M plan for future CSP plants is presented. Parabolic trough solar technology is employed at Kramer Junction. However, many of the O&M improvements described in the report are also applicable to CSP plants based on solar power tower or dish/engine concepts.

  5. A standardized and safe method of sterile field maintenance during intra-operative horizontal plane fluoroscopy

    Full Text Available Abstract Background Intra-operative fluoroscopy for orthopaedic procedures frequently involves imaging in the horizontal plane, which requires the lower portion of the C-arm (x-ray tube to be rotated from an unsterile zone (beneath the table into the sterile field. To protect the integrity of the sterile field the C-arm must be draped repeatedly throughout the surgical case. The current, un-standardized, practice employs draping procedures which violate the Association of peri-Operative Registered Nurses (AORN Standards and Recommended Practices, waste time and material, and pose an increased risk for surgical site infection. Presentation of the hypothesis Use of a novel sterile C-arm drape (C-armor that maintains the integrity of the sterile field, will improve operating room efficiency and reduce surgical site infection risk factors. This reduction in risk factors may potentially reduce surgical site infections in orthopaedic surgical cases requiring repeated horizontal x-ray imaging. Testing the Hypothesis Savings in time and material and the reduction in surgical site infection risk factors afforded by using C-armor are intuitive to those skilled in the practice of orthopaedic surgery. Testing for a reduction in the number of microorganisms introduced to the surgical site by improved C-arm draping would be challenging due to the multiple confounding factors during a surgical operation. Determination of an absolute reduction in surgical site infections may be possible, but will require accounting for many confounding variables and a large study sample in order to achieve statistical significance. Implications of the Hypothesis Improved intraoperative workflow, healthcare savings and a reduction in surgical site infection risk factors will be achieved by utilizing a standardized and safe method of sterile field maintenance during intra-operative horizontal plane fluoroscopy.

  6. Intelligent Systems and Advanced User Interfaces for Design, Operation, and Maintenance of Command Management Systems

    1998-01-01

    Historically Command Management Systems (CMS) have been large, expensive, spacecraft-specific software systems that were costly to build, operate, and maintain. Current and emerging hardware, software, and user interface technologies may offer an opportunity to facilitate the initial formulation and design of a spacecraft-specific CMS as well as a to develop a more generic or a set of core components for CMS systems. Current MOC (mission operations center) hardware and software include Unix workstations, the C/C++ and Java programming languages, and X and Java window interfaces representations. This configuration provides the power and flexibility to support sophisticated systems and intelligent user interfaces that exploit state-of-the-art technologies in human-machine systems engineering, decision making, artificial intelligence, and software engineering. One of the goals of this research is to explore the extent to which technologies developed in the research laboratory can be productively applied in a complex system such as spacecraft command management. Initial examination of some of the issues in CMS design and operation suggests that application of technologies such as intelligent planning, case-based reasoning, design and analysis tools from a human-machine systems engineering point of view (e.g., operator and designer models) and human-computer interaction tools, (e.g., graphics, visualization, and animation), may provide significant savings in the design, operation, and maintenance of a spacecraft-specific CMS as well as continuity for CMS design and development across spacecraft with varying needs. The savings in this case is in software reuse at all stages of the software engineering process.

    Most power plant operators responded to the liberalisation of the European energy markets by lowering their costs. The measures they took to this end such as lengthening maintenance intervals, cutting down on operating staff and progressively outsourcing maintenance services have indeed had an impact, albeit not as intended. In the meantime some power plants are showing first signs of impaired availability and reliability, both of which criteria had begun to play a more prominent role again in recent years. Today's challenge on power supply companies therefore is to optimise the costs and availability of their plants simultaneously. The ''McKinsey Power Gauge'', a Europe-wide benchmarking system provides assistance in identifying successful operating and maintenance strategies.

    In operating and maintaining its regional power transmission system, Bonneville Power Administration (BPA) must address environmental concerns. Pollution sources and pathways for pollution migration, including potential contamination from hazardous or toxic materials, are present. BPA must develop and follow precautionary measures, respond to emergencies, minimize wastes, redress past problems, alert and train employees to problems and safety needs, constantly evaluate this effort and update the program for improvements and changes in regulations and technology. Part of BPA's mission is to conduct its operation, maintenance, and replacement programs in an environmentally sound manner. BPA recognizes its responsibility to be good stewards of the environment. BPA will meet its environmental obligations as set forth in environmental laws and regulations. BPA intends to make consistent and measurable progress toward meeting these responsibilities. The target for the 10-Year Plan is to achieve environmental compliance and meet the following goals: (1) protect human health and the environment; (2) avoid or limit liability (3) set up an effective internal management structure to maintain compliance; and (4) achieve cost-effective compliance. 6 figs.

    Full Text Available During the pilot phase of the Mediterranean Forecasting System (MFSPP (2000 2003, a prototype observing system (Mediterranean Moored Multi-sensor Array – M3A was designed, developed and operated in the Cretan Sea for continuous oceanographic measurements in real time. The main problems encountered were associated with biofouling, underwater and aerial communication and with the design of the surface buoy. In the second phase of the MFS project named Mediterranean Forecasting System Towards Environmental Predictions (MFSTEP (2003–2005, the aim was to solve those problems and to consolidate the M3A. For the minimisation of biofouling a pilot field study was performed and the techniques of bromine solution and copper shielding were evaluated. Additionally, the oligotrophy of the Aegean Sea dictated the need to ignore factory calibrations and to perform site-specific laboratory calibrations of the sensors. This procedure was proved necessary and produced calibration coefficients that gave results comparable to the measurements obtained with the laboratory analysis method. During the approximately five years of operation, there were 13 scheduled and 15 emergency visits, with a total duration of 65 days. The acquired experience through the maintenance program proved that the continuous observation of such a very important system with a relative low cost is feasible.

    1998-06-01

    A survey was conducted to determine operation and maintenance (O and M)-related materials needs in geothermal power plants and to identify future research and development to address these needs. A total of 44 questionnaires was mailed to geothermal plant operators and industry consultants. The response rate was 54%. The participants were asked to describe type and frequency of materials problems, strategies currently used to mitigate such problems, barriers to using new or alternative materials and technologies, sources of information and give their views on research and development priorities. A wide range of opinions was obtained, reflecting each individual respondent`s perspective and the site-specific nature of some problems. However, the consensus is that corrosion and scaling remain major issues and that components requiring performance improvements include pipelines, well casing, turbines, heat exchangers, condensers, valves and cooling towers. It is recommended that appropriate research and development continue to be directed at reducing O and M costs associated with materials failure or inadequate service. There should be a balance between optimizing existing materials through better design and understanding of behavior in geothermal environments and development of new materials. Life extension of existing equipment, service life prediction, education of plant personnel in materials and methods for mitigating corrosion, and improvements in inhibitors and biocides would also be beneficial.

    Seaside nuclear power plants have to face the ageing of nuclear reactor cooling piping systems. In order to minimize the duration of the production unit shutdown, maintenance operations have to be planned well in advance. In a context where owners of infrastructures tend to extend the life span of their goods while having to keep the safety level maximum, it is more and more important to develop high level expertise and know-how in management of infrastructures life cycle. A patented monitoring technique based on optic fiber sensors, has been designed. This preventive maintenance enables the owner to determine criteria for network replacement based on degradation impacts. A methodology to evaluate and optimize operation budgets, depending on predictions of future functional deterioration and available maintenance solutions, has been developed and applied. (authors)

  17. Maintenance and resupply in the unpressurized environment - Design and operational concepts for the Space Station Freedom logistics carriers

    Creps, Gary M.; Ernst, Steven A.; Crawford, Robert D.

    1991-01-01

    A significant percentage of the maintenance tasks for Space Station Freedom are anticipated to be conducted in the unpressurized environment. The maintenance concept for this environment essentially involves the removal and replacement of relatively large orbital replacement units (ORUs). Major constraints will be the on-orbit availability of both crew time and spare ORUs. The challenge presented to the program will be the performance of unpressurized cargo resupply that provides maximum cargo-carrying capability (mass and volume) and flexibility (type and quantity), while minimizing the impact to maintenance task times. The design of the logistics carriers is a critical component for successful resupply and maintenance operations, and to the success of Space Station Freedom.

  18. Specific cerebral networks for maintenance and response organization within working memory as evidenced by the 'double delay/double response' paradigm.

    2005-07-01

    Most of the working memory (WM) tasks used in functional imaging studies are based on the principle of the delayed response in which both the storage and the response organization are present during the delay period. It is therefore difficult to isolate activation specific to the storage function from that specific to the organization of the response. To determine the specific neural networks associated with these two WM operations, we performed a functional MRI study in healthy subjects using a new paradigm, 'the double delay/double response' tasks. This paradigm isolates maintenance from response organization by dividing the delay into two separate parts, the first being dedicated to memory, while the second includes response organization. Activation within the dorsolateral prefrontal cortex (DLPFC) followed a relative hemispheric dissociation: activation related to maintenance was predominant in the right DLPFC but was only detected when the load exceeded three items. Activation related to response organization was predominant in the left DLPFC, regardless of whether this response was based on information held in WM ('memory guided') or was independent of WM ('visually-guided'). These results suggest that activation of the DLPFC, should be interpreted in terms of executive processing for both maintenance and response organization.

  19. The plant cell wall integrity maintenance mechanism-concepts for organization and mode of action.

    2015-02-01

    One of the main differences between plant and animal cells are the walls surrounding plant cells providing structural support during development and protection like an adaptive armor against biotic and abiotic stress. During recent years it has become widely accepted that plant cells use a dedicated system to monitor and maintain the functional integrity of their walls. Maintenance of integrity is achieved by modifying the cell wall and cellular metabolism in order to permit tightly controlled changes in wall composition and structure. While a substantial amount of evidence supporting the existence of the mechanism has been reported, knowledge regarding its precise mode of action is still limited. The currently available evidence suggests similarities of the plant mechanism with respect to both design principles and molecular components involved to the very well characterized system active in the model organism Saccharomyces cerevisiae. There the system has been implicated in cell morphogenesis as well as response to abiotic stresses such as osmotic challenges. Here the currently available knowledge on the yeast system will be reviewed initially to provide a framework for the subsequent discussion of the plant cell wall integrity maintenance mechanism. The review will then end with a discussion on possible design principles for the cell wall integrity maintenance mechanism and the function of the plant turgor pressure in this context. © The Author 2014.

  20. FON2 SPARE1 redundantly regulates floral meristem maintenance with FLORAL ORGAN NUMBER2 in rice.

    Directory of Open Access Journals (Sweden)

    Takuya Suzaki

    2009-10-01

    Full Text Available CLAVATA signaling restricts stem cell identity in the shoot apical meristem (SAM in Arabidopsis thaliana. In rice (Oryza sativa, FLORAL ORGAN NUMBER2 (FON2, closely related to CLV3, is involved as a signaling molecule in a similar pathway to negatively regulate stem cell proliferation in the floral meristem (FM. Here we show that the FON2 SPARE1 (FOS1 gene encoding a CLE protein functions along with FON2 in maintenance of the FM. In addition, FOS1 appears to be involved in maintenance of the SAM in the vegetative phase, because constitutive expression of FOS1 caused termination of the vegetative SAM. Genetic analysis revealed that FOS1 does not need FON1, the putative receptor of FON2, for its action, suggesting that FOS1 and FON2 may function in meristem maintenance as signaling molecules in independent pathways. Initially, we identified FOS1 as a suppressor that originates from O. sativa indica and suppresses the fon2 mutation in O. sativa japonica. FOS1 function in japonica appears to be compromised by a functional nucleotide polymorphism (FNP at the putative processing site of the signal peptide. Sequence comparison of FOS1 in about 150 domesticated rice and wild rice species indicates that this FNP is present only in japonica, suggesting that redundant regulation by FOS1 and FON2 is commonplace in species in the Oryza genus. Distribution of the FNP also suggests that this mutation may have occurred during the divergence of japonica from its wild ancestor. Stem cell maintenance may be regulated by at least three negative pathways in rice, and each pathway may contribute differently to this regulation depending on the type of the meristem. This situation contrasts with that in Arabidopsis, where CLV signaling is the major single pathway in all meristems.

    Full Text Available This lecture focuses on the complexity to manage and optimize maintenance processes, operations and service tasks to equipments and systems installed at customer sites. Different locations, access and working environment may compromise any standardization of setup's and operations. Multi-site teams based on geographic strategic locations, adds complexity to trainning, communication, supervising and monitoring processes. Logistics and information systems assume relevant rolls to consolidate global performance. Beside efficiency, effectiveness productivity and flexibility, field teams need skills on autonomy responsibility and proactivity. This lecture also explores the needed adaptation of most part of available literature, normally based on production sites, as also of Lean- Kaizen principles to the fact that services can not be stocked, quality is normally more difficult to measure and customer is normally present when and where service is produced.

  7. Wind turbine reliability :understanding and minimizing wind turbine operation and maintenance costs.

    Energy Technology Data Exchange (ETDEWEB)

    Walford, Christopher A. (Global Energy Concepts. Kirkland, WA)

    2006-03-01

    Wind turbine system reliability is a critical factor in the success of a wind energy project. Poor reliability directly affects both the project's revenue stream through increased operation and maintenance (O&M) costs and reduced availability to generate power due to turbine downtime. Indirectly, the acceptance of wind-generated power by the financial and developer communities as a viable enterprise is influenced by the risk associated with the capital equipment reliability; increased risk, or at least the perception of increased risk, is generally accompanied by increased financing fees or interest rates. This paper outlines the issues relevant to wind turbine reliability for wind turbine power generation projects. The first sections describe the current state of the industry, identify the cost elements associated with wind farm O&M and availability and discuss the causes of uncertainty in estimating wind turbine component reliability. The latter sections discuss the means for reducing O&M costs and propose O&M related research and development efforts that could be pursued by the wind energy research community to reduce cost of energy.

    2011-12-01

    We tested the association of common events in drinking water distribution systems with contamination of household tap water with human enteric viruses. Viruses were enumerated by qPCR in the tap water of 14 municipal systems that use non-disinfected groundwater. Ultraviolet disinfection was installed at all active wellheads to reduce virus contributions from groundwater to the distribution systems. As no residual disinfectant was added to the water, any increase in virus levels measured downstream at household taps would be indicative of distribution system intrusions. Utility operators reported events through written questionnaires. Virus outcome measures were related to distribution system events using binomial and gamma regression. Virus concentrations were elevated in the wells, reduced or eliminated by ultraviolet disinfection, and elevated again in distribution systems, showing that viruses were, indeed, directly entering the systems. Pipe installation was significantly associated with higher virus levels, whereas hydrant flushing was significantly associated with lower virus levels. Weak positive associations were observed for water tower maintenance, valve exercising, and cutting open a water main. Coliform bacteria detections from routine monitoring were not associated with viruses. Understanding when distribution systems are most vulnerable to virus contamination, and taking precautionary measures, will ensure delivery of safe drinking water.

    As a regulator fairly new to the American Society of Mechanical Engineers (ASME) Operations and Maintenance (O&M) Committee process, the author does not have a personal historical perspective as do many of the longer-term, and highly respected, members of the O&M Committee. However, as Branch Chief of the Mechanical Engineering Branch, Division of Engineering, in the Office of Nuclear Reactor Regulation at the NRC for just over two years, he has responsibility for the regulatory agency`s review of licensee actions involving the products that come from the efforts of the O&M Committee, as well as responsibility for portions of the activities of interest to other ASME Code groups such as Section III, Section XI, and Qualification of Mechanical Equipment. As a result, the author has learned a great deal about the code process in a short time. Here he gives his perspectives on the process and provides a few thoughts on the direction for the future.

They are identified by Bonneville Power Administration as follows: (1) Operations and Maintenance--Project No. 1983-350-00, Contract No. 4504, and (2) Planning and Design--Project No. 1983-350-00, Contract No. 4035. The Operations and Maintenance (O&M) budget of $2,166,110 was divided as follows: Facility Development and Fish Production Costs--$860,463; and Equipment Purchases as capital cost--$1,305,647 for equipment and subcontracts. The Planning and Design (P&D) budget of $170,381 was allocated to development of a Coho master planning document in conjunction with Nez Perce Tribal Hatchery. The O&M budget expenditures represent personnel and fish production expenses; e.g., administration, management, coordination, facility development, personnel training and fish production costs for spring Chinook and Coho salmon. Under Objective 1: Fish Culture Training and Education, tribal staff worked at Clearwater Anadromous Hatchery (CAFH) an Idaho Department of Fish and Game (IDFG) facility to produce spring Chinook smolt and parr for release that are intended to provide future broodstock for NPTH. As a training exercise, BPA allowed tribal staff to rear Coho salmon at Dworshak National Fish Hatchery, a U.S. Fish and Wildlife Service (USFWS) facility. This statement of work allows this type of training to prepare tribal staff to later rear salmon at Nez Perce Tribal Hatchery under Task 1.6. As a subset of the O&M budget, the equipment purchase budget of $1,305,647 less $82,080 for subcontracts provides operational and portable equipment necessary for NPTH facilities after construction. The equipment budget for the year was $1,223,567; this year's purchases amounted $287,364.48 (see

    Full Text Available Facilities management in Malaysia has started as early as 1990s during the development of mega projects such as Putrajaya in 1999 [8, 9]. During this period, Malaysia was introduced to an integrated property management and maintenance services known as facilities management. However, its implementation according to the standard practice is still being disputed. The purpose of facilities management standard practices is to provide the facility management profession with a leading reference on facilities management activities and standards. Therefore, the determination of how far the gap in FM current practice is essential to help our FM industry. Thus, the aim of this study is to establish the gap between the current practices and the standard practices and also how far the gap should be satisfied. A set of questionnaire was designed upon literature and previous research done to gather the required information. The study is subjected to FM organizations in private sectors and only the personnel at management level are assessed. There were certified that most of the practices that assessed by means of gap analysis had an acceptable result which the gap between the current practices and the standard practices are not too far.

    This plan has been developed by Westinghouse Hanford Company (WHC), and its subcontractors ICF Kaiser Hanford (ICF KH) and BCS Richland, Inc. (BCSR), at the direction of the US Department of Energy (DOE), Richland Operations Office (RL). WHC and its subcontractors are hereafter referred to as the Maintenance and Operations (M and O) Contractor. The plan identifies actions involving the M and O Contractor that are critical to (1) prepare for a smooth transition to the Project Hanford Management Contractor (PHMC), and (2) support and assist the PHMC and RL in achieving transition as planned, with no or minimal impact to ongoing baseline activities. The plan is structured around two primary phases. The first is the pre-award phase, which started in mid-February 1996 and is currently scheduled to be completed on June 1, 1996, at which time the contract is currently planned to be awarded. The second is the follow-on four-month post-award phase from June 1, 1996, until October 1, 1996. Considering the magnitude and complexity of the scope of work being transitioned, completion in four months will require significant effort by all parties. To better ensure success, the M and O Contractor has developed a pre-award phase that is intended to maximize readiness for transition. Priority is given to preparation for facility assessments and processing of personnel, as these areas are determined to be on the critical path for transition. In addition, the M and O Contractor will put emphasis during the pre-award phase to close out open items prior to contract award, to include grievances, employee concerns, audit findings, compliance issues, etc.

    DODD, E.N.

    1999-05-12

    This Basis for Interim Operation (BIO) was developed for the PUREX end state condition following completion of the deactivation project. The deactivation project has removed or stabilized the hazardous materials within the facility structure and equipment to reduce the hazards posed by the facility during the surveillance and maintenance (S and M) period, and to reduce the costs associated with the S and M. This document serves as the authorization basis for the PUREX facility, excluding the storage tunnels, railroad cut, and associated tracks, for the deactivated end state condition during the S and M period. The storage tunnels, and associated systems and areas, are addressed in WHC-SD-HS-SAR-001, Rev. 1, PUREX Final Safety Analysis Report. During S and M, the mission of the facility is to maintain the conditions and equipment in a manner that ensures the safety of the workers, environment, and the public. The S and M phase will continue until the final decontamination and decommissioning (D and D) project and activities are begun. Based on the methodology of DOE-STD-1027-92, Hazards Categorization and Accident Analysis Techniques for Compliance with DOE Order 5480.23, Nuclear Safety Analysis Reports, the final facility hazards category is identified as hazards category This considers the remaining material inventories, form and distribution of the material, and the energies present to initiate events of concern. Given the current facility configuration, conditions, and authorized S and M activities, there are no operational events identified resulting in significant hazard to any of the target receptor groups (e.g., workers, public, environment). The only accident scenarios identified with consequences to the onsite co-located workers were based on external natural phenomena, specifically an earthquake. The dose consequences of these events are within the current risk evaluation guidelines and are consistent with the expectations for a hazards category 2

    The NORSOK initiative was taken in 1993 to improve the competitive position of the Norwegian Shelf. To mobilize as much engagement and support as possible for this work, top leaders from the oil companies, the industry and various authorities were gathered to form a development and operation forum for the petroleum sector that recommended the proposals made by the working groups. These leaders were supposed to provide for implementation in their own organizations. The NORSOK work is being continued jointly by OLF (Oljeindustriens Landsforening) and TBL (Teknologibedriftenes Landsforening). A liaison committee was appointed and it decided that the experience from NORSOK so far should be examined, with an emphasis on working processes between the oil companies and the industry. The committee decided to give preference to development rather than operation (Capex before Opex). The entire NORSOK has been very focused on Capex and the large cost overruns. The operation environment has been put into the shade. A sub committee under the liaison committee has been established that will rectify the situation. An important issue to be addressed by the sub committee will be the transfer of experience from the operation phase to the new projects. The composition and mandate of the subcommittee are described in detail.

    UNAVCO has now completed its third year of operation of the 138 continuous GPS stations, 12 tiltmeters and 31 communications relays that comprise the Alaska Region of the Earthscope Plate Boundary Observatory. Working in Alaska has been challenging due to the extreme environmental conditions encountered and logistics difficulties. Despite these challenges we have been able to complete each summer field season with network operation at 95% or better. Throughout the last three years we have analyzed both our successes and failures to improve the quality of our network and better serve the scientific community. Additionally, we continue to evaluate and deploy new technologies to improve station reliability and add to the data set available from our stations. 2011 was a busy year for the Alaska engineering team and some highlights from last year's maintenance season include the following. This spring we completed testing and deployment of the first Inmarsat BGAN satellite terminal for data telemetry at AC60 Shemya Island. Shemya Island is at the far western end of the Aleutian Islands and is one of the most remote and difficult to access stations in the PBO AK network. Until the installation of the BGAN, this station was offline with no data telemetry for almost one year. Since the installation of the BGAN in early April 2011 dataflow has been uninterrupted. This year we also completed the first deployments of Stardot NetCamSC webcams in the PBO Network. Currently, these are installed and operational at six GPS stations in Alaska, with plans to install several more next season in Alaska. Images from these cameras can be found at the station homepages linked to from the UNAVCO website. In addition to the hard work put in by PBO engineers this year, it is important that we recognize the contributions of our partners. In particular the Alaska Volcano Observatory, the Alaska Earthquake Information Center and others who have provided us with valuable engineering assistance

    To improve asthma disease management, the National Asthma Education Program (NAEP) Expert Panel published Guidelines for the Diagnosis and Management of Asthma in 1991. To compare the current status of asthma disease management among patients in a large health maintenance organization with the NAEP guidelines and to identify the factors that may be associated with medical care (eg, emergency department visits and hospital admissions) and adherence to the guidelines. Analyses of 1996 survey data from 5580 members with asthma (age range, 14 to 65 years) covered by a major health maintenance organization in California (Health Net). In general, adherence to NAEP guidelines was poor. Seventy-two percent of respondents with severe asthma reported having a steroid inhaler, and of those, only 54% used it daily. Only 26% of respondents reported having a peak flowmeter, and of those, only 16% used it daily. Age (older), duration of asthma (longer), increasing current severity of disease, and treatment by an asthma specialist correlated with daily use of inhaled steroids. Ethnicity (African American and Hispanic) correlated negatively with inhaled steroid use but positively with emergency department visits and hospital admissions for asthma. Increasing age and treatment by an asthma specialist were also identified as common factors significantly related to the daily use of a peak flowmeter and, interestingly, to overuse of beta2-agonist metered-dose inhalers. Although the NAEP guidelines were published 7 years ago, compliance with the guidelines was low. It was especially poor for use of preventive medication and routine peak-flow measurement. Furthermore, the results showed that asthma specialists provided more thorough care than did primary care physicians in treating patients with asthma. Combining the results of the regression analyses revealed that some of the variation in rates of emergency department visits and hospitalizations among some subpopulations can be

    Spitz, B

    1979-01-01

    Health Maintenance Organization (HMOs) are repeatedly described as a general solution to the health care crisis and a specific solution to the problems confronting Medicare and Medicaid. The potential incorporation of HMOs into Medicaid has promised to improve the states' ability to accurately budget program expenditures, simplify management, eliminate abusive practices directly linked to fee-for-service (e.g., billing for undelivered services for providing unnecessary care) and, most important, contain costs. At the same time it has promised to increase access to mainstream medicine. Experience has shown, however, that the promise has often been severely compromised by unethical HMO marketing practices, inadequacy of services and excessive administrative costs. This article examines some of the reasons: the political process which created HMOs, the rhetorical claims which exaggerated the strengths of prepaid group practice and distorted the formulation of policy, and the peculiar characteristics of the Medicaid program which have caused Medicaid HMOs to deviate considerably from theoretical expectations.

    Full Text Available Purpose: Although knowledge and its management is, and has been, studied in depth, particularly since the 90’s decade of the past century, especially for the strategic management, innovation, trade, or business administration, there are still many questions on how it articulates or transfers and the barriers to its management, especially when we talk about internal tactical activities that affect staff that we could call "offices", such as maintenance and industrial assembly or exploitation and conduction of the facilities. Because of the peculiarities normally seen in this kind of activity in the industrial companies, the knowledge of these people is strongly based on their experience (strong tacit component, difficult to measure and articulate, and on many occasions, however, this rupture of information-knowledge, can represent a high cost for the company (often assumed to be something inevitable due to the increase in production and service downtime, loss of efficiency, or tuning time of new staff to these areas.Design/methodology/approach: After a description of the State of the art and the basic principles of knowledge management, a qualitative study in an industrial company has been carried out, within the areas of operation and maintenance, in order to know the barriers and facilitators that such involved personnel finds in order to achieve an adequate transmission and use of that knowledge.Findings and Originality/value: Learn about barriers, facilitators and impact that offers the knowledge management in the areas of industrial maintenance, especially among professionals in offices which operate with a high degree of tacit knowledge and with a heavy dependence on the company on these professionals.Research limitations/implications: Those characteristics of a qualitative study in a particular area and within a geographical area, although it can be extrapolated to other types of companies and regional areas.Practical implications: Learn

  5. VALIDATION OF SPRING OPERATED PRESSURE RELIEF VALVE TIME TO FAILURE AND THE IMPORTANCE OF STATISTICALLY SUPPORTED MAINTENANCE INTERVALS

    Energy Technology Data Exchange (ETDEWEB)

    Gross, R; Stephen Harris, S

    2009-02-18

    The Savannah River Site operates a Relief Valve Repair Shop certified by the National Board of Pressure Vessel Inspectors to NB-23, The National Board Inspection Code. Local maintenance forces perform inspection, testing, and repair of approximately 1200 spring-operated relief valves (SORV) each year as the valves are cycled in from the field. The Site now has over 7000 certified test records in the Computerized Maintenance Management System (CMMS); a summary of that data is presented in this paper. In previous papers, several statistical techniques were used to investigate failure on demand and failure rates including a quantal response method for predicting the failure probability as a function of time in service. The non-conservative failure mode for SORV is commonly termed 'stuck shut'; industry defined as the valve opening at greater than or equal to 1.5 times the cold set pressure. Actual time to failure is typically not known, only that failure occurred some time since the last proof test (censored data). This paper attempts to validate the assumptions underlying the statistical lifetime prediction results using Monte Carlo simulation. It employs an aging model for lift pressure as a function of set pressure, valve manufacturer, and a time-related aging effect. This paper attempts to answer two questions: (1) what is the predicted failure rate over the chosen maintenance/ inspection interval; and do we understand aging sufficient enough to estimate risk when basing proof test intervals on proof test results?

    To evaluate the feasibility and reliability of (1) identifying Health Maintenance Organization (HMO) membership by ascertaining self-reported health plan name in a telephone survey and (2) using external information to determine whether the plan was an HMO. Respondents to the 1999-2001 Massachusetts Behavioral Risk Factor Surveillance System (BRFSS) and the 1999 Massachusetts Colorectal Cancer (CRC) survey were asked to name their health plan. The authors used information from external sources to classify the plan as an HMO or a non-HMO. Test-retest reliability of reported plan name was examined overall, by demographic characteristics, and by health plan name. Reliability of HMO classification was tested with the kappa statistic. More than 88 percent of respondents with commercial health insurance provided their health plan name; 84 percent reported a plan that could be assigned as either an HMO or a non-HMO. The percentage whose HMO status could be assigned differed by demographic characteristics. Among those assigned, the distribution of specific HMOs among survey respondents was similar to the distribution reported by the Massachusetts Division of Insurance. In a subsample, 78 percent reported the same health plan during a follow-up interview. Agreement was higher for men, and differed according to the plan reported at the first time point. Kappa for HMO classification from health plan name was 0.87. Self-report of health plan name is a feasible and reliable method to ascertain health insurance information in a telephone interview.

  7. Competition between health maintenance organizations and nonintegrated health insurance companies in health insurance markets.

    Science.gov (United States)

    Baranes, Edmond; Bardey, David

    2015-12-01

    This article examines a model of competition between two types of health insurer: Health Maintenance Organizations (HMOs) and nonintegrated insurers. HMOs vertically integrate health care providers and pay them at a competitive price, while nonintegrated health insurers work as indemnity plans and pay the health care providers freely chosen by policyholders at a wholesale price. Such difference is referred to as an input price effect which, at first glance, favors HMOs. Moreover, we assume that policyholders place a positive value on the provider diversity supplied by their health insurance plan and that this value increases with the probability of disease. Due to the restricted choice of health care providers in HMOs a risk segmentation occurs: policyholders who choose nonintegrated health insurers are characterized by higher risk, which also tends to favor HMOs. Our equilibrium analysis reveals that the equilibrium allocation only depends on the number of HMOs in the case of exclusivity contracts between HMOs and providers. Surprisingly, our model shows that the interplay between risk segmentation and input price effects may generate ambiguous results. More precisely, we reveal that vertical integration in health insurance markets may decrease health insurers' premiums.

    1982-11-01

    Relationships between life stress and illness form the basis of much current thinking and practice in psychosomatic medicine. This study examines a particular life stress, marital separation, in a controlled, prospective design. Participants are 237 Health Maintenance Organization [HMO] subscribers followed over a two-year period. Marital separation was experienced by 117 of these participants early in the two-year study period. A stratified random half of these separated individuals participated in a short-term psychoeducational group intervention, "Seminars for the Separated." Measures of psychosocial adjustment and medical utilization were analyzed to describe correlates of experiencing marital separation and to evaluate the intervention. Statistically significant increases in medical utilization by people experiencing marital separation were observed in comparisons with married control subjects. Much of this increased utilization is in the year surrounding the actual separation and is accounted for by mental health visits. Effects of the intervention were not evident until controls for baseline levels of medical utilization were introduced. Even then, intervention effects were slight. Methodological problems and implications for further study are presented.

    Hepatitis C affects an estimated 130 million people worldwide and is a major cause of chronic liver disease. This retrospective database study aims to describe the epidemiology of HCV-infected patients in Maccabi Healthcare Services, a 2-million-member health maintenance organization in Israel. HCV was identified by cross-linking diagnoses, laboratory data, and dispensed HCV treatment (1993-2013). The point-prevalence of HCV in 2012 and annual incidence of newly-diagnosed HCV during 2003-2012 (index period) were calculated. The age-adjusted prevalence of HCV was 5.19/1,000 population (n = 10,648). The highest prevalence was found among males and in patients aged 35-54 years. Two thirds of HCV-infected patients were immigrants from the former Soviet Union (FSU). HCV genotype 1 was predominant (67%). A total of 6,150 patients were newly diagnosed with HCV infection during the index period. The age-standardized rate of newly-diagnosed HCV declined from over 50/100,000 (2003) to 15/100,000 (2012). This rate was highest in males from the FSU, particularly for birth cohorts in 1950-70. The study results suggest that the reported incidence of HCV infection in Israel is declining, while prevalence is particularly high among FSU immigrants and genotype 1 is predominant. As the HCV treatment landscape evolves, these estimates can inform future studies and health technology assessments.

    DNV Renewables (USA) Inc. (DNV) used an Operations and Maintenance (O&M) Cost Model to evaluate ten distinct cost scenarios encountered under variations in wind turbine component failure rates. The analysis considers: (1) a Reference Scenario using the default part failure rates within the O&M Cost Model, (2) High Failure Rate Scenarios that increase the failure rates of three major components (blades, gearboxes, and generators) individually, (3) 100% Replacement Scenarios that model full replacement of these components over a 20 year operating life, and (4) Serial Failure Scenarios that model full replacement of blades, gearboxes, and generators in years 4 to 6 of the wind project. DNV selected these scenarios to represent a broad range of possible operational experiences. Also in this report, DNV summarizes the predominant financing arrangements used to develop wind energy projects over the past several years and provides summary data on various financial metrics describing those arrangements.

    2015-01-01

    This Operations, Maintenance, and Monitoring Report (OMMR) presents the findings, observations, and results from operation of the air sparging (AS) interim measure (IM) for Hot Spot (HS) Areas 1, 2, and 5 at the Converter Compressor Building (CCB) located at Kennedy Space Center (KSC), Florida. The objective of the IM at CCB HS Areas 1, 2, and 5 is to decrease concentrations of volatile organic compounds (VOCs) in groundwater in the treatment zones via AS to levels that will enable a transition to a monitored natural attenuation (MNA) phase. This OMMR presents system operations and maintenance (O&M) information and performance monitoring results since full-scale O&M began in June 2014 (2 months after initial system startup in April 2014), including quarterly performance monitoring events in July and October 2014 and January and May 2015. Based on the results to date, the AS system is operating as designed and is meeting the performance criteria and IM objective. The performance monitoring network is adequately constructed for assessment of IM performance at CCB HS Areas 1, 2, and 5. At the March 2014 KSC Remediation Team (KSCRT) Meeting, team consensus was reached for the design prepared for expansion of the system to treat the HS 4 area, and at the November 2014 KSCRT Meeting, team consensus was reached that HS 3 was adequately delineated horizontally and vertically and for selection of AS for the remedial approach for HS 3. At the July 2015 KSCRT meeting, team consensus was reached to continue IM operations in all zones until HSs 3 and 4 is operational, once HS 3 and 4 zones are operational discontinue operations in HS 1, 2, and 5 zones where concentrations are less than GCTLs to observe whether rebounding conditions occur. Team consensus was also reached to continue quarterly performance monitoring to determine whether operational zones achieve GCTLs and to continue annual IGWM of CCB-MW0012, CCBMW0013, and CCB-MW0056, located south of the treatment area.

    2007-01-01

    Otolaryngological examination was carried out of 80 engineers and technicians engaged in maintenance of aircrafts in the airports. They are continuously exposed to occupational aviation noise and therefore are at risk for chronic neurosensory hypoacusis. Pure tone audiogram registers in them a rise in hearing thresholds throughout the whole band of frequencies studied. This means that aviation maintenance staff is exposed to noise containing highly intensive infrasound and high-frequency components. The detected pathology directly correlated with duration of exposure to noise. Development of neurosensory hypoacusis in aviation maintenance specialists starts earlier than in other specialists exposed to noise.

    To document the quality of diabetes care provided to patients in a large health maintenance organization (HMO) from 1 January 1993 to 1 January 1994 and compare it to the standards of the American Diabetes Association (ADA). To meet a Health Plan and Employer Data Information Set (HEDIS) requirement, a major HMO in California identified 14,539 members with diabetes and randomly selected 384 individuals for review. Charts were available on 353 of these patients, and after obtaining the information for the HEDIS review, additional information was extracted from the charts by an outside chart reviewer. This data set was used for an analysis of the quality of diabetic care provided by the participating medical groups to these HMO members during 1 year. Documentation of follow-up and measures of glycemic and lipid control was examined both for absolute values and for the frequency of measurement over the year. These results were compared to the ADA standards of care. Although patients averaged 4.5 visits to their primary care physicians (PCPs) over the year, 21% had one or fewer visits per year. Glycated hemoglobin levels were not documented in 56% of patients (ADA recommends two to four measurements per year), and of those with a glycated hemoglobin level measured. 39% had at least one value > or = 10%. Fasting plasma glucose concentrations were not documented in 65% of patients (four to six per year recommended). Foot exams (which should be performed at each regular visit) were not documented for 94% of patients. Urine protein measurements were not performed in 52% of patients. Additionally, many patients had elevated and untreated lipid abnormalities. In spite of the frequency of PCP visits during the year for many of these patients, diabetes management was inadequate. This lack of adequate preventive care will lead to an increased risk of the development of the acute and chronic complications of diabetes, creating an even greater future burden on the health care

    2012-09-01

    This research presents a disaggregated modeling approach for investigating the link between winter road collision occurrence, weather, road surface conditions, traffic exposure, temporal trends and site-specific effects. This approach is unique as it allows for quantification of the safety effects of different winter road maintenance activities at an operational level. Different collision frequency models are calibrated using hourly data collected from 31 different highway routes across Ontario, Canada. It is found that factors such as visibility, precipitation intensity, air temperature, wind speed, exposure, month of the winter season, and storm hour have statistically significant effects on winter road safety. Most importantly, road surface conditions are identified as one of the major contributing factors, representing the first contribution showing the empirical relationship between safety and road surface conditions at such a disaggregate level. The applicability of the modeling framework is demonstrated using several examples, such as quantification of the benefits of alternative maintenance operations and evaluation of the effects of different service standards using safety as a performance measure.

    The underlying structure and organization of a group strongly influences its effectiveness and efficiency. An operations group may develop a 'persistence of form' that prevents it from responding to changes in responsibilities and technology. Even if a group has been in existence for a long time, it is a good idea to re-evaluate its structure periodically. An organization can possess an aesthetic quality related to how simple and transparent its functions appear to users and other outsiders. Information and tasks should flow freely without undue impedance. In this session we examined the issue of group design from a variety of perspectives including both large and small labs, commercial operations and that of an 'expert' consultant. (author)

    2017-09-01

    Full Text Available This study aims to determine the effect of building design's inaccuracy against the cost of maintenance, by taking the research in Serayu Opak River Basin Organization, Water Resources Field and Water Resources Management Center in Yogyakarta Special Region. The first step is to analyze the inaccuracy of building design based on the result of interview and observation during field survey. The second step is to analyze the cost of building maintenance. The third step is to analyze the maintenance costs used to minimize the effects of the inaccurate design of the building. The result shows the inaccuracy of building design in the form of the use of clear glass without coated glass film and the absence of heat insulator on the roof of the building cause the room to become hot. The installation of rain gutters without vertical pipes, toilet facilities in the entire building is not yet complete, inadequate accessibility for persons with disabilities, and inadequate corridor design. There is a small portion of the maintenance budget used for reducing the impact of building design's inaccuracy, so it can be concluded that the design of the building is less meet the requirements of the Government regulations.

    Industry in the Pacific Northwest consumes a significant percentage of the total regional electric load; however, industrial demand-side management resource development activities in this sector are underdeveloped. One such opportunity for electricity resource development is through maintenance (O&M) activities. Despite the importance of industry in the Pacific Northwest, little information has been available on the DSM resource potential, particularly through O&M activities. To obtain this information, the Bonneville Power Administration commissioned Pacific Northwest Laboratory to study the DSM resource potential that may be achieved through O&M practices in Pacific Northwest industries. The information from this report will be used to identify one or more specific O&M activities or industries having significant opportunity for reducing electricity consumption for further evaluation in future tasks to this project. The overall goal of this project is to determine, confirm, and develop the conservation resources that can be achieved from O&M practices in Pacific Northwest industries. This project is developmental in nature because its scope involves a sizable task whose path and direction is difficult to define in advance. The primary focus of this report is to summarize the major findings of the literature and datareview. Detailed analysis and use of all data gathered in the review are beyond the scope this study. However, the reported findings in this analysis provide an extensive framework for identifying and estimating the electric resource potential available in the industrial manufacturing sector.

    Organic light-emitting transistors (OLETs) represent an emerging class of organic optoelectronic devices, wherein the electrical switching capability of organic field-effect transistors (OFETs) and the light-generation capability of organic light-emitting diodes (OLEDs) are inherently incorporated in a single device. In contrast to conventional OFETs and OLEDs, the planar device geometry and the versatile multifunctional nature of OLETs not only endow them with numerous technological opportunities in the frontier fields of highly integrated organic electronics, but also render them ideal scientific scaffolds to address the fundamental physical events of organic semiconductors and devices. This review article summarizes the recent advancements on OLETs in light of materials, device configurations, operation conditions, etc. Diverse state-of-the-art protocols, including bulk heterojunction, layered heterojunction and laterally arranged heterojunction structures, as well as asymmetric source-drain electrodes, and innovative dielectric layers, which have been developed for the construction of qualified OLETs and for shedding new and deep light on the working principles of OLETs, are highlighted by addressing representative paradigms. This review intends to provide readers with a deeper understanding of the design of future OLETs.

    Rainwater harvesting and water reuse are receiving increasing attention as they hold the potential to effectively improve water conservation efforts. While many technical solutions have been developed, alternative water systems in built environments face significant challenges in the implementation and operational phases. The aim of this study is to examine obstacles to the implementation of alternative water systems in practice and identify criteria of feasible and sustainable solutions that allow bypassing of the identified obstacles. Interviews were conducted with planners, system designers and operators to find out which factors that central actors believe influence successful implementation of such systems. The results were analyzed in light of the literature. The actual performance of the water harvesting and reuse systems in four recently built green buildings in the Province of British Columbia, Canada was analyzed in light of the predicted outcome, according to the criteria identified in the interviews. It was found that the major obstacle to success is that the practical challenges involved in the implementation of alternative systems are underestimated. This, for example, leads to that education strategies for operational staff are not developed, and the staff is left floundering. This study highlights the importance of recognizing the need for strategic and directed educational programs for the human resources who are involved in operating and maintaining rainwater harvesting and water reuse systems.

    Virtual human techniques have been used a lot in industrial design in order to consider human factors and ergonomics as early as possible. The physical status (the physical capacity of virtual human) has been mostly treated as invariable in the current available human simulation tools, while indeed the physical capacity varies along time in an operation and the change of the physical capacity depends on the history of the work as well. Virtual Human Status is proposed in this paper in order to assess the difficulty of manual handling operations, especially from the physical perspective. The decrease of the physical capacity before and after an operation is used as an index to indicate the work difficulty. The reduction of physical strength is simulated in a theoretical approach on the basis of a fatigue model in which fatigue resistances of different muscle groups were regressed from 24 existing maximum endurance time (MET) models. A framework based on digital human modeling technique is established to realiz...

    With the increasingly severe energy shortage and climate change problems, developing wind power has become a key energy development strategy and an inevitable choice to protect the ecological environment worldwide. The purpose of this study was to investigate the prevalence of low back pain (LBP) and analyze its risk factors among operation and maintenance personnel in wind farms (OMPWF). A cross-sectional survey of 151 OMPWF was performed, and a comprehensive questionnaire, which was modified and combined from Nordic Musculoskeletal Questionnaires (NMQ), Washington State Ergonomics Tool (WSET) and Syndrome Checklist-90(SCL-90) was used to assess the prevalence and risk factors of LBP among OMPWF. The prevalence of LBP was 88.74 % (134/151) among OMPWF. The multivariable model highlighted four related factors: backrest, somatization, squatting and lifting objects weighing more than 10 lb more than twice per minute. The prevalence of LBP among OMPWF appears to be high and highlights a major occupational health concern.

    Operations and Maintenance (O and M) expenditures by nuclear power plant owner/operators possess a very logical and vital link in considerations relating to plant safety and reliability. Since the determinants of O and M outlays are considerable and varied, the potential linkages to plant safety, both directly and indirectly, can likewise be substantial. One significant issue before the US Nuclear Regulatory Commission is the impact, if any, on O and M spending from state programs that attempt to improve plant operating performance, and how and to what extent these programs may affect plant safety and pose public health risks. The purpose of this study is to examine the role and degree of impacts from state promulgated economic incentive programs (EIPs) on plant O and M spending. A multivariate regression framework is specified, and the model is estimated on industry data over a five-year period, 1986--1990. Explanatory variables for the O and M spending model include plant characteristics, regulatory effects, financial strength factors, replacement power costs, and the performance incentive programs. EIPs are found to have statistically significant effects on plant O and M outlays, albeit small in relation to other factors. Moreover, the results indicate that the relatively financially weaker firms are more sensitive in their O and M spending to the presence of such programs. Formulations for linking spending behavior and EIPs with plant safety performance remains for future analysis.

  17. The impact of heat exchanger fouling on the optimum operation and maintenance of the Stirling engine

    This paper focuses on the effect of heat exchanger fouling on the performance of the Stirling engine in combined heat and power (CHP) application. Fouling results from using biomass fuels and affects the heat exchanger that transfers heat into the engine. This heat exchanger is referred to as the heater. The heat exchanger that recovers heat from the flue gases is also affected by fouling. To determine the performance of the Stirling engine, a commercial Stirling analysis tool is applied together with models that have been developed for the heat transfer in the heater, regenerator and cooler of the engine. The Stirling engine model uses constant temperatures for the heat addition and rejection, with the theory of displacement engine as a basis. The fouling in the heat exchanger is taken into account by using a fouling factor that corresponds with the degradation in the total heat transfer coefficient. The Stirling engine model together with the model for heat exchanger fouling makes it possible to estimate the effect of fouling on the performance of the Stirling engine. A cost model is developed for the engine to translate changes in performance into economy in CHP operation. In the studied application, the Stirling engine is operated by the heat demand. Together with the selected control method, performance and cost models compose a tool for the simulation and optimization of the system. The use of the models to determine the optimal cleaning interval of the heat exchanger surfaces is considered. (author)

    The demonstration of continuous-wave lasing from organic semiconductor films is highly desirable for practical applications in the areas of spectroscopy, data communication, and sensing, but it still remains a challenging objective. We report low-threshold surface-emitting organic distributed feedback lasers operating in the quasi–continuous-wave regime at 80 MHz as well as under long-pulse photoexcitation of 30 ms. This outstanding performance was achieved using an organic semiconductor thin film with high optical gain, high photoluminescence quantum yield, and no triplet absorption losses at the lasing wavelength combined with a mixed-order distributed feedback grating to achieve a low lasing threshold. A simple encapsulation technique greatly reduced the laser-induced thermal degradation and suppressed the ablation of the gain medium otherwise taking place under intense continuous-wave photoexcitation. Overall, this study provides evidence that the development of a continuous-wave organic semiconductor laser technology is possible via the engineering of the gain medium and the device architecture.

    Anadromous salmonid stocks have declined in both the Grande Ronde River Basin (Lower Snake River Compensation Plan (LSRCP) Status Review Symposium 1998) and in the entire Snake River Basin (Nehlsen et al. 1991), many to the point of extinction. The Grande Ronde River Basin historically supported large populations of fall and spring chinook (Oncorhynchus tshawytscha), sockeye (O. nerka), and coho (O. kisutch) salmon and steelhead trout (O. mykiss) (Nehlsen et al. 1991). The decline of chinook salmon and steelhead populations and extirpation of coho and sockeye salmon in the Grande Ronde River Basin was, in part, a result of construction and operation of hydroelectric facilities, over fishing, and loss and degradation of critical spawning and rearing habitat in the Columbia and Snake River basins (Nehlsen et al. 1991). Hatcheries were built in Oregon, Washington and Idaho under the Lower Snake River Compensation Plan (LSRCP) to compensate for losses of anadromous salmonids due to the construction and operation of the lower four Snake River dams. Lookingglass Hatchery (LGH) on Lookingglass Creek, a tributary of the Grande Ronde River, was completed under LSRCP in 1982 and has served as the main incubation and rearing site for chinook salmon programs for Grande Ronde and Imnaha rivers in Oregon. Despite these hatchery programs, natural spring chinook populations continued to decline resulting in the National Marine Fisheries Service (NMFS) listing Snake River spring/summer chinook salmon as ''threatened'' under the federal Endangered Species Act (1973) on 22 April 1992. Continuing poor escapement levels and declining population trends indicated that Grande Ronde River basin spring chinook salmon were in imminent danger of extinction. These continuing trends led fisheries co-managers in the basin to initiate the Grande Ronde Endemic Spring Chinook Salmon Supplementation Program (GRESCSSP) in order to prevent extinction and preserve options for use of

    The meristem initiates lateral organs in a regular manner, and proper communication between the meristem and the lateral organs ensures the normal development of plants. Here, we show that mutation of the rice (Oryza sativa) gene TONGARI-BOUSHI1 (TOB1) results in pleiotropic phenotypes in spikelets, such as the formation of a cone-shaped organ instead of the lemma or palea, the development of two florets in a spikelet, or premature termination of the floret meristem, in addition to reduced growth of the lemma or palea and elongation of the awn. These phenotypes seem to result from not only failure in growth of the lateral organs, but also defects in maintenance and organization of the meristem. For example, the cone-shaped organ develops as a ring-like primordium from an initial stage, suggesting that regulation of organ initiation in the meristem may be compromised. TOB1 encodes a YABBY protein, which is closely related to FILAMENTOUS FLOWER in Arabidopsis thaliana, and is expressed in the lateral organ primordia without any patterns of polarization. No TOB1 expression is detected in the meristem, so TOB1 may act non–cell autonomously to maintain proper meristem organization and is therefore likely to play an important role in rice spikelet development.

    This paper tests for the existence and magnitude of economies of scale and scope as possible explanations for the recent observed trends in increasing health maintenance organization (HMO) scale (through merger and acquisition) and scope (through greater participation in public enrollee markets) using firm level data from a sample of California HMOs for the time period 1986-1992. The results suggest that economies of scale provide a strong justification for mergers only in the case of relatively small HMOs (i.e. those with fewer than 115,000 enrollees), and economies of scope do not explain the increasing HMO enrollment of public enrollees.

    Full Text Available Petrol Fuel Stations (PFS is the most commonly available hazardous facility within urban and rural areas. Hazardous materials such as petrol, diesel, Compressed Natural Gas (CNG and kerosene oil normally sell and stores at PFS. PFS can be considered as small refinery within the city. A 3.5 year study conducted and 3216 non-compliances were recorded from PFS located in various cities of Pakistan. The operating company was ISO 14001 and OHSAS 18001 certified. The recorded non-compliances during study period were categorized into 8 potential factors. These were Housekeeping (HK, Transportation Hazard (TH, Slips, Trips and Falls (STF, Carelessness (C, Fire Risks (FR, Electrical Fault (EF, Miscellaneous Cases (MC and Medical Treatment Cases (MTC. Analytical Hierarchy Process (AHP was used and categorized 8 factors were prioritized. The same data was further classified based upon to cause fatality, accident, incident and near miss cases. A total numbers of 14, 426, 975 and 1804, fatality, accident, incident and near miss cases were recorded. With application of Exponential Smoothing method the fatalities, accident, incident and near miss cases for the years 2011, 2012 and 2013 were forecasted. The results of AHP and forecasted hazards will be presented and discussed in this study. It is hope that the both approaches will assist health and safety professionals for future hazards predictions and hazards weights determinations. Health and safety practitioners can take remedial and preventative measures by using past data with utilization of proposed techniques.

    2012-03-02

    Organic field-effect transistors (OFETs) are considered in technological applications for which low cost or mechanical flexibility are crucial factors. The environmental stability of the organic semiconductors used in OFETs has improved to a level that is now sufficient for commercialization. However, serious problems remain with the stability of OFETs under operation. The causes for this have remained elusive for many years. Surface potentiometry together with theoretical modeling provide new insights into the mechanisms limiting the operational stability. These indicate that redox reactions involving water are involved in an exchange of mobile charges in the semiconductor with protons in the gate dielectric. This mechanism elucidates the established key role of water and leads in a natural way to a universal "stress function", describing the stretched exponential-like time dependence ubiquitously observed. Further study is needed to determine the generality of the mechanism and the role of other mechanisms. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  10. Capacity optimization of battery-generator hybrid power system: Toward minimizing maintenance cost in expeditionary basecamp/operational energy applications

    Science.gov (United States)

    Onwuanumkpe, Jude C.

    Low and transient load condition are known to have deleterious impact on the efficiency and health of diesel generators (DGs). Extensive operation under such loads reduces fuel consumption and energy conversion efficiency, and contribute to diesel engine degradation, damage, or catastrophic failure. Non-ideal loads are prevalent in expeditionary base camps that support contingency operations in austere environments or remote locations where grid electricity is either non-existent or inaccessible. The impact of such loads on DGs exacerbates already overburdened basecamp energy logistics requirements. There is a need, therefore, to eliminate or prevent the occurrence of non-ideal loads. Although advances in diesel engine technologies have improved their performance, DGs remain vulnerable to the consequences of non-ideal loads and inherent inefficiencies of combustion. The mechanisms through which DGs respond to and mitigate non-ideal loads are also mechanically stressful and energy-intensive. Thus, this research investigated the idea of using batteries to prevent DGs from encountering non-ideal loads, as a way to reduce basecamp energy logistics requirements. Using a simple semi-empirical approach, the study modeled and simulated a battery-DG hybrid system under various load conditions. The simulation allowed for synthesis of design space in which specified battery and generator capacity can achieve optimal savings in fuel consumption and maintenance cost. Results show that a right-sized battery-diesel generator system allows for more than 50% cost savings relative to a standalone generator.

    During future ITER maintenance operations, sensors and their embarked electronics will be exposed to a hostile and radioactive environment. This paper presents the design of a MGy radiation tolerant 16 bit resolver-to-digital converter (RDC) in 130 nm CMOS technology. The RDC features a Type II digital tracking loop, able to track resolvers with speeds up to 300 rps, and excitation frequencies up to 4 kHz. The RDC uses two integrated ΔΣ-analog-to-digital converters (ADCs) to digitize the resolver outputs. The 16 bit, 10 kHz ADCs utilize a correlated double sampling technique to remove radiation induced offset and 1/f-noise. The front-end features a static angular resolution of 16 bits (4.2 arcsec{sub rms}) and a resolution of 10 bits (6 arcmin{sub rms}) at a rotor speed of 100 rps. The circuit has a simulated radiation tolerance exceeding 1 MGy. It has the ability to operate under temperatures up to 125 °C, and to allow multiplexing with signals from other conventional sensors for compact, robust read-out architectures.

    Due to the scheduling inefficiency in a large number of job requests for the network operation and maintenance of field operations and the jobs being unable to change adjustment issue, an on-site job scheduling algorithm based on improved genetic algorithm for network operation and maintenance is estab-lished. The algorithm is based on job-indirect encoding resources, combined with network operation and maintenance of on-site job resource scheduling features, by setting the upper limit of the number of jobs for each maintenance personnel to avoid excessive burden on maintenance staff, thus helping to improve the quality of service and resource utilization. The simulation results show that the use of genetic algo-rithms is effective in solving the network operation and maintenance resource scheduling.%针对网络运维现场作业调度中大量作业任务请求时效率低下、作业任务有所改变时无法自行调整等问题,提出基于改进遗传算法的网络运维中现场作业调度算法。该算法基于作业任务-资源的间接编码方式,结合网络运维中现场作业资源调度的特点,通过对每个维护人员设置作业任务数量的上限,避免某个维护人员负担任务数量过多,有利于提高服务质量以及资源的利用率。经过仿真实验,结果表明使用遗传算法可有效解决网络运维中资源调度问题。

  16. Maintenance of Mouse Gustatory Terminal Field Organization Is Disrupted following Selective Removal of Peripheral Sodium Salt Taste Activity at Adulthood.

    Skyberg, Rolf; Sun, Chengsan; Hill, David L

    2017-08-09

    Neural activity plays a critical role in the development of central circuits in sensory systems. However, the maintenance of these circuits at adulthood is usually not dependent on sensory-elicited neural activity. Recent work in the mouse gustatory system showed that selectively deleting the primary transduction channel for sodium taste, the epithelial sodium channel (ENaC), throughout development dramatically impacted the organization of the central terminal fields of three nerves that carry taste information to the nucleus of the solitary tract. More specifically, deleting ENaCs during development prevented the normal maturation of the fields. The present study was designed to extend these findings by testing the hypothesis that the loss of sodium taste activity impacts the maintenance of the normal adult terminal field organization in male and female mice. To do this, we used an inducible Cre-dependent genetic recombination strategy to delete ENaC function after terminal field maturation occurred. We found that removal of sodium taste neural activity at adulthood resulted in significant reorganization of mature gustatory afferent terminal fields in the nucleus of the solitary tract. Specifically, the chorda tympani and greater superficial petrosal nerve terminal fields were 1.4× and 1.6× larger than age-matched controls, respectively. By contrast, the glossopharyngeal nerve, which is not highly sensitive to sodium taste stimulation, did not undergo terminal field reorganization. These surprising results suggest that gustatory nerve terminal fields remain plastic well into adulthood, which likely impacts central coding of taste information and taste-related behaviors with altered taste experience.SIGNIFICANCE STATEMENT Neural activity plays a major role in the development of sensory circuits in the mammalian brain. However, the importance of sensory-driven activity in maintaining these circuits at adulthood, especially in subcortical structures, appears to be

    Objective: To investigate the mental status, level of occupational health knowledge, health behaviors, and occupational health knowledge demand in operating and maintenance personnel in wind power plants, and to provide a basis for formulating protective measures of occupational health for operating and maintenance personnel in wind power plants. Methods: A cluster sampling was performed in regionally representative wind power plants in the wind power industry from May 2014 to June 2015, and the Symptom Checklist-90 (SCL-90) and a self-made evaluation questionnaire were used to investigate the general status, mental health, and occupational health knowledge demand in 160 operating and maintenance workers. Results: Of all respondents, 26.9% had mental health issues. The awareness rate of infectious disease knowledge and preventive measures was 11.9%. Of all workers, 96.5% wanted to know the occupational hazard factors in the workplace, and 96.3% wanted to get the knowledge of the prevention of related diseases. Conclusion: Mental health issues in operating and maintenance personnel in wind power plants cannot be neglected and there is a high demand for occupational health services and related knowledge. Comprehensive intervention measures for health promotion in the workplace should be adopted to improve working environment, enhance individual mental health education, increase the level of occupational health management, and protect the health of workers.

    The lubricating oil system provides a means to introduce a lubricant in the form of a film to reduce friction and wear between surfaces that bear against each other as they move.1 The oil film which is established also cools the parts by carrying generated heat away from hot surfaces, cleans and carries dirt or metal wear particles to the filter media, and helps seal the piston to the cylinder during combustion. Most systems are pressure lubricated and distribute oil under pressure to bearings, gears, and power assemblies. Lubricating oil usually reaches main, connecting rod, and camshaft bearings through drilled passages in the cylinder block and crankshaft or through piping and common manifolds.Many parts rely on oil for cooling, so if the lube oil system fails to perform its function the engine will overheat. Metal to metal surfaces not separated by a thin film of oil rapidly build up frictional heat. As the metals reach their melting point, they tend to weld together in spots or streaks. Lube oil system failures can cause significant damage to an engine in a short period of time. Proper maintenance and operation of the lubricating oil system is essential if your engine is to accomplish its mission.

    Full Text Available Urges for sustainable development had pushed the government and professional bodies to respond and react by implementing regulations where possible to direct development in that manner. However, the outcome in most financial conferences and dialogues on sustainable buildings flagged on high construction and maintenance cost. Thus, this study is conducted to collect and analyze actual building operation and maintenance cost between GBI and Non-GBI rated buildings in Malaysia which are more than 2 years fully operated buildings. There are two categories of selected buildings which are residential and non-residential type of building. Each category of the building consists of similar building’s characteristic such as geographic location, mode of operation, building heights, total numbers of floors and units. The scope of building’s maintenance for this study is mainly on wear and tear of the wall painting, electrical light fittings, ceiling panels, roofing system and mechanical services like water pump system are recorded for their replacement frequency of service and the cost involved within a consistent period of 12 months operation at cost percentage saving of 78.9% and 40.4% for residential and non-residential buildings respectively compare against Non-GBI rated buildings. Electricity consumption for GBI rated buildings are lower than Non-GBI rated buildings which recorded at the cost variance of 23.8% and 6.3% and water consumption at 35.9% and 44.0% for the above mentioned two main categories of selected case study buildings. Results from this study conclude major savings on residential buildings category in term of maintenance cost and electricity consumption for GBI rated buildings. Whereby, non-residential category of buildings, GBI rated building had been proven to obtain significant savings in terms of maintenance cost and water consumption.

    This study compared the factor structure and burnout scores obtained on the Maslach Burnout Inventory from 84 pharmacists in Health Maintenance Organizations (HMO) with the normative data for USA pharmacists. Results provided empirical support for the reliability and validity of the inventory to measure burnout within the profession of pharmacy. Values of Cronbach coefficient alpha for subscales of Emotional Exhaustion, Depersonalization, and Personal Accomplishment were similar to those obtained with the normative sample. Factor analysis was conducted to yield the best three-factor solution. Derived factor loadings matched the three hypothesized subscales. On Personal Accomplishment the mean subscale score for HMO pharmacists was significantly higher than the normative score. Given limitations of the small sample, research is indicated to substantiate use of the inventory among HMO pharmacists.

  13. Using operational and defined fractions to assess soil organic matter stabilization and structure

    Studies on soil organic matter (SOM) began with alkaline solvents revealing a dark colored substance that could be isolated under low pH. Further studies revealed fulvic and humic acids and humin fractions leading to theories on functional groups and metal-clay bridging mechanisms. The fate of isotopes in these fractions revealed soil carbon pools with varying turnover rates with half the soil carbon (C) in humin and acid hydrolyzed fractions over 1000 years old. These results are the basis of the three pool conceptual framework used in many biogeochemical models. Theories on the role of functional groups and compound classes further elaborated concepts on physical (aggregates) and chemical mechanisms of C stabilization. With the advance of analytical instrumentation, the operational fractions were further defined to the compound and molecular levels. These studies confirmed the majority of soil C is microbially derived. Our observation that all microbial groups contributed nonselectively to soil C maintenance independent of mineralogy suggests that compound characteristics within integrated structures are more important than the source of individual compounds for stabilizing soil C. In dissolved organic C floccing studies using Near Edge X-ray Fine Structure analysis, we found that aromatic compounds interacted first with Fe, however, the majority of direct bonds to Fe were polysaccharides, reinforcing that an integrative chemical structure rather than direct bonds imparted stability in organo-metal interactions. Using a novel differential scanning calorimeter coupled to an isotope ratio mass spectrometer setup, we confirmed that the presence of clays (independent of clay type) increased the microbial utilization of calcium stabilized high versus low temperature compounds, asserting that higher temperature compounds (i.e., phenolics) are likely less tightly bound by clay minerals. The integration of operational and defined fractions of SOM remains a legitimate

    There is a strong demand for systems that can give early warnings on upcoming problems in process performance or sensor measurements. In this project we have developed and implemented such a system on-line. The goal with the system is to give warnings about both faults needing urgent actions, as well giving advice on roughly when service may be needed for specific functions. The use of process simulation models on-line can offer a significant tool for operators and process engineers to analyse the performance of the process and make the most correct and fastest decision when problems arise. In this project physical simulation models are used in combination with decision support tools. By using a physical model it is possible to compare the measured data to the data obtained from the simulation and give these deviations as input to a decision support tool with Bayesian Networks (BN) that will result in information about the probability for wrong measurement in the instruments, process problems and maintenance needs. The application has been implemented in a CFB boiler at Maelarenergi AB. After tuning the model the system has been used online during September - October 2010 and May - October 2011, showing that the system is working on-line with respect to running the simulation model but with batch runs with respect to the BN. Examples have been made for several variables where trends of the deviation between simulation results and measured data have been used as input to a BN, where the probability for different faults has been calculated. Combustion up in the separator/cyclones has been detected several times, problems with fuel feed on both sides of the boiler as well. A moisture sensor not functioning as it should and suspected malfunctioning temperature meters as well. Deeper investigations of the true cause of problems have been used as input to tune the BN

    为改善多部件系统运营的管理水平和经济效益,基于可修部件检查率的动态控制策略,提出一种主动维护方案.基于独立性原理,分别建立了多部件系统在主动维护、被动维护和冗余备用维护管理下的数学模型,分析了可修部件在主动维护、被动维护和冗余管理模型下的可靠性及平均无故障工作时间(MTTF),以及部件在稳态运行时的期望维修费用和需求量.计算结果表明:基于主动维护的管理模型投资回收期最短,被动维护次之,冗余维护最差.在多部件系统运行维护管理中,基于检查率动态控制策略的主动维护方案是行之有效的手段.%In order to improve the management levels and economic benefits of multi-component system operation, a novel proactive maintenance scheme is proposed based on the dynamic control strategy of the check rate of the repairable components. Based on the dependability principle, the mathematical models are established under the conditions of the proactive maintenance, the passive maintenance, and the redundant maintenance, respectively. And then the reliability and mean time to failure (MTTF) are discussed under three kinds of models for repairable components, as well as the expected maintenance cost and quantity demanded. The computation results show that the investment recovery period is the shortest applying the proactive maintenance scheme, and the one of the passive maintenance scheme is the inferior, and the one of the redundant maintenance scheme is the worst. The research shows that the proactive maintenance scheme using the dynamic control strategy for the check rate is an effective management measure in the multi-component system.

    Full Text Available ABSTRACT:Resveratrol, is a polyphenol that can be extracted from grapes and red wine, possess potential anti-inflammatory effects, which would result in the reduction of cytokine production, the alteration of the expression of adhesion molecule molecules, and the inhibition of neutrophil function. Resveratrol might also act as an antioxidant, anti-aging, and control of cell cycle and apoptosis. Resveratrol has been shown to have protective effects for patients inshock-like states. Such protective phenomenon is reported to be implicated in a variety of intracellular signaling pathways including the regulation of the mitogen-activated protein kinases (MAPK/ hemeoxygenase-1 (HO-1 pathway, activates estrogen receptor (ER, and the mediation of pro-inflammatory cytokines, reactive oxygen species (ROS formation and reactive. Moreover, through anti-inflammatory effects and antioxidant properties, the resveratrol is believed to maintain organ function following trauma-hemorrhage.

    Previous assessments of the prevalence of resistant hypertension (RH) in uncontrolled blood pressure (BP) have ranged from 3% to 30%. Using real-world data, our aim was to estimate the prevalence of RH in patients belonging to the Maccabi Healthcare Services, a 2-million-member health organization in Israel. From 2010 to 2011, all hypertensive patients with ≥2 recorded BP measurements during a minimum period of 6 months were identified. Patients were considered uncontrolled if their most recent BP during the study period and their mean systolic BP or diastolic BP during a preceding period of ≥6months were systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg, or systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg in chronic kidney disease or diabetes mellitus. Uncontrolled patients taking diuretics and ≥2 antihypertensive therapy classes at their maximal recommended dose were regarded as resistant hypertensives. A total of 172 432 patients were eligible for the study. Uncontrolled BP was found in 35.9% (n=65 710). Overall, 2.2% of the uncontrolled patients (n=1487) were resistant hypertensives. Patients with RH were characterized by a significantly (Phypertension receiving equivalent treatment. The results of this large population-based study indicate a substantially lower prevalence of RH than previously reported. Most patients with uncontrolled BP took less than the maximal recommended antihypertensive treatment.

    Meng, Y Y; Jatulis, D E; McDonald, J P; Legorreta, A P

    1997-04-01

    This study was designed to determine the levels and predictors of Medicare enrollees' satisfaction with access to medical care and quality of health care in a health maintenance organization. Data collected by an instrument adapted from the Group Health Association of America's Consumer Satisfaction Survey were analyzed after being linked with administrative data. In general, Medicare enrollees reported high satisfaction with both access to and quality of health care. Most members (96%) rated skill, experience, and training of physicians and the friendliness and courtesy of the staff favorably. A lower percentage of members (77%) rated favorably the ability to contact a physician after hours. Levels of satisfaction were essentially not explained by patient characteristics such as age, sex, geographic region, medications, or utilization. Stepwise regression identified the ease of arranging appointments as the strongest predictor of satisfaction, with access to care and outcomes of medical care as the strongest predictor of overall satisfaction with quality of health care. These findings indicate that items that members rated least favorably, such as ability to contact a physician after hours, added little to the prediction of satisfaction with access to and quality of health care.

    1999-09-01

    The increasing enrollment of Medicare beneficiaries in health maintenance organizations (HMOs) in recent years has caused concern about whether HMOs and their providers have created an unfavorable environment for members who are chronically ill. This study was designed to examine whether there are any differences in disenrollment rates among enrollees with diabetes and enrollees without diabetes. This was a 4-year longitudinal follow-up study with a matched cohort. Medicare beneficiaries (aged > or =65 years) with diabetes identified through pharmacy records in 1994 were matched with a comparison group according to age, sex, comorbidities, and type of provider groups in an HMO in California. The overall distribution of the characteristics of members in the diabetic and matched nondiabetic group is almost identical. The matched-pair chi2 tests indicated that there were no statistical differences in disenrollment rates between diabetic and nondiabetic members during all three follow-up periods (P = 0.16-0.85). We found that the HMO members with diabetes did not disenroll from the HMO at a higher rate than those without diabetes. The findings should alleviate some of the concern that HMOs and their contracted providers have created an unattractive environment for members who have chronic diseases such as diabetes.

  3. Business Process Re-engineering: A Panacea for Reducing Operational Cost in Service Organizations

    Directory of Open Access Journals (Sweden)

    Joseph Joseph Sungau

    2015-03-01

    Full Text Available Organizations in today’s business environment struggle on how to reduce operation cost in order to set prices that can be afforded by many customers while obtaining reasonable profit.  In order to reduce Operational Cost, service organizations have been working hard to identify techniques that facilitate business processes improvement for reduced Operational Cost. In so doing, the global literature indicates that service organizations adopt Business Process Re-engineering technique as a panacea of reducing Operational Cost. Despite a documented potentiality of Business Process Re-engineering technique, there are mixed empirical results, findings and conclusions regarding the effect of Business Process Re-engineering on Operational Cost. Therefore, this paper aimed at assessing and explaining effects of BPR on Operational Cost.   The study used cross-sectional survey design to investigate the effect of BPR on Operational Cost. Intensive literature review enabled the construction of structural measurement model, formulation of testable hypotheses and operationalization of constructs. In order to test the model and hypotheses, data were collected from ninety five (95 service organizations in Tanzania. Results of the study reveal that BPR and delivering speed have no direct effects on Operational Cost; they indirectly affect Operational Cost through the mediations of service quality. Therefore, BPR influences first both service quality and delivery speed in affecting Operational Cost of service organizations. It is now recommended that service organizations should use Business Process Re-engineering as panacea of reducing Operational Cost.

    1990-08-01

    The computerized outpatient records of the Harvard Community Health Plan, a 230,000-member health maintenance organization, were used to determine the frequency with which serum sickness is recognized in the practice setting after exposure to antibiotics. The medical records of 3,487 children who had been prescribed cefaclor or amoxicillin were searched in December 1986 for coded diagnoses of serum sickness and related conditions. Diagnoses were validated by blinded review of dictated and written office notes. There were 12 cases of serum sickness in 11,523 child-years. During this time, these children were prescribed 13,487 courses of amoxicillin, 5,597 courses of trimethoprim-sulfamethoxazole (TMP-SMZ), 3,553 courses of cefaclor, and 2,325 courses of penicillin V. Serum sickness was considered to be antibiotic-related if it occurred within 20 days of initiation of antibiotic therapy. Five cases were temporally associated with cefaclor, one with both amoxicillin and TMP-SMZ, four with TMP-SMZ alone, and one with penicillin V alone. One case was not associated with any antibiotic exposure. All antibiotic-related cases occurred in children under age 6 years who were treated for otitis media or streptococcal pharyngitis, and most cases began 7-11 days after initiation of antibiotic. All but one of the antibiotic-related cases occurred in children who had relatively heavy lifetime antibiotic exposure. The risk of serum sickness was significantly elevated after cefaclor compared with amoxicillin, even among the most heavily exposed children (relative risk = 14.8, p = 0.01, 95% confidence interval 2.0-352.0). Most cases prompted several physician visits, but none required hospitalization.

    Petitti, Diana B; Xie, Fagen; Barzilay, Joshua I

    2006-10-01

    The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) published its main findings in December, 2002. It recommended thiazide diuretics as a first-line treatment of hypertension. The current study describes the prescribing patterns of thiazide diuretics in four regions of Kaiser Permanente, a large national United States Health Maintenance Organization--two regions that had an ALLHAT clinical center and two that did not. We tested the hypothesis that participation in a clinical trial leads to quicker and greater adoption of study recommendations than non-participation in a trial. The relative percentage of filled outpatient prescriptions for the period 2 or 3 years before the ALLHAT main publication through December 31, 2004 was calculated by region for thiazide-type diuretics and for calcium channel blockers (CCBs), beta-blockers, central alpha-blockers, angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs) and other antihypertensive diuretics. In the 2 years after publication of the ALLHAT trial findings, the percentage of all prescriptions for thiazide diuretics increased from 11.2% to 12.4% in the two regions with an ALLHAT clinical site and from 8.9% to 10.1% in the two regions without an ALLHAT clinical site (p > 0.05). The percentage of new prescriptions for thiazide diuretics increased from 13.7% to 16.6% in the two regions with an ALLHAT clinical site and from 10.8% to 13.0% in the two regions without an ALLHAT clinical site (p > 0.05). Participation in a clinical hypertension study does not appear to accelerate adoption of study recommendations.

    Studies in multiple sclerosis (MS) suggest a trend of increasing disease prevalence and incidence, and especially, a disproportional increase in the incidence of multiple sclerosis in women. The objective of this study was to evaluate the incidence of MS over 22 years and to determine the ratio in incidence of men to women in a health maintenance organization from Buenos Aires, Argentina. The population was made up of all members of a hospital-based HMO affiliated between January 1992 and December 2013. Each person was followed contributing time at risk. Cases with definite diagnosis of MS were included. Incidence density was calculated with 95 % confidence intervals and compared between women and men. 165,456 subjects were followed for a total of 1,488,575 person-years, of whom 42 developed MS. Incidence density was 3/100,000 person-years (95 % CI 2.1-3.5/100,000 person-years). During this period (1992-2013), the incidence rate in women increased from 1/100,000 (95 % CI 0.8-1.6) to 4.9/100,000 (95 % CI 4.1-5.4) (p incidence ranged from 1.4/100,000 (95 % CI 1-1.7) to 1.8 (1.3-2.1) (p = 0.16). Incidence density during the study period increased significantly in women but not in men. This is the first report of this phenomenon in Latin America region.

    Greig, E.

    2004-07-01

    This is the fifth of seven reports in this series on specific aspects of the monitoring and evaluation of the Blyth offshore wind farm project. The report assesses the operation and maintenance (O and M) costs for the wind farm in its first full year of operation, and extrapolates these costs to give indicative costs for larger projects. It identifies both planned regular costs and unplanned site maintenance costs; some costs can be attributed to 'troubleshooting' during installation and would not be expected in future years. The Blyth wind farm, the first in the UK, consists of two 2 MW wind turbines installed approximately 1 km from the coast in water about 6 m deep at low tide. The site is exposed to the full impact of the North Sea weather, breaking waves and a significant tidal range (about 5 m). Location, boat availability, weather and insurance are identified as the key factors affecting O and M costs for future offshore wind farms in the UK.

    2012-09-01

    Full Text Available A field-based study was performed to broaden our knowledge of operational efficiency losses associated with the neglect of the proper maintenance of the delimbing and feeding mechanisms of a harvester. The post-harvest assessments of industrial round-wood (IRW processing damage, fuel consumption and productivity were examined in clearcutting operations. Observations were made of seven combinations of wear levels of feed rollers (A—heavy, B—medium, C and C’—without wear and sharpening states of delimbing knives (1—incorrect, 2—correct, depending on the degree of feed roller wear and matching of angles of knife blades to the technical requirements. The processing defects of IRW were broken down into unprocessed branches, bark stripping, and damage caused by feed roller spikes. The results were then compared with the effective quality requirements, and the IRW losses in terms of the reject rates (RR were determined in the context of the technical condition. The most frequent damage was by unprocessed branches. The harvester with correctly sharpened knives produced the minimum RR (4% of pine, 6% of spruce and 6% birch logs. The quality of IRW harvested under B1 and C1 resulted in 6%, 6% and 8%. A1 turned out to be the lowest (12%, 10% and 8%. Improvement in the maintenance of delimbing knives can reduce the RR of IRW by 5%. Timely restoration of worn-out rollers can increase productivity by 2% and reduce fuel consumption by 5%.

  9. Significance of Building Maintenance Management Systems towards Sustainable Development

    Directory of Open Access Journals (Sweden)

    M.A. Othuman Mydin

    2014-05-01

    Full Text Available Building maintenance management is an organized and effective system of maintenance operations which is set up to deal with problems related to the upkeep of a building. Its goal, aside from locating and remedying a building’s deficiencies, is to effectively minimize the overall costs of maintenance and is also an effort to maximize the gain and benefits from the savings. There are a few factors that influence decisions to undertake maintenance work. The principal goal of maintenance is to protect a building in the early stage of issues as they arise. Some major reasons for maintaining a building include retaining its reputation and value of investments, maintaining the building in a condition which allows it to accomplish its purpose, and presenting a good outer shell. This paper will review and discuss some of the major elements of building maintenance towards achieving sustainable buildings.

  10. Examining maintenance responsibilities.

    Lam, K C

    2001-06-01

    This paper has examined the important responsibilities of the two organisations involved in the provision of maintenance service for the vital building services in many of our highly serviced buildings. The issues raised could be put to beneficial use in both clients and maintenance providers. All in all, the clients should work closely with their maintenance providers. Engineering services in buildings will not perform satisfactorily and efficiently if both parties do not work together and understand the maintenance tasks based on a business partnering mode. Put forward is the view that the management of the activities involved in the operation and maintenance process is a "shared commitment/involvement" between the client and the maintenance provider. It is obvious that many factors can influence the continued effectiveness of a quality maintenance scheme set up by client and provider. Some of these factors are: Change in key personnel Updates in technology Amendments to engineering practice Implementation of legislative requirements Changes in operation by client or provider Change of use of building Passage of time These factors must be fully reviewed by both parties from time to time, and necessary actions taken. A cooperative team working relationship and improved communication should be fostered by the client and his provider for the best management of services maintenance. This arrangement will contribute to better building services systems with continuous improvement; improved value for clients and higher return for the maintenance provider.

  11. Integrating International Engineering Organizations For Successful ISS Operations

    Blome, Elizabeth; Duggan, Matt; Patten, L.; Pieterek, Hhtrud

    2006-01-01

    The International Space Station (ISS) is a multinational orbiting space laboratory that is built in cooperation with 16 nations. The design and sustaining engineering expertise is spread worldwide. As the number of Partners with orbiting elements on the ISS grows, the challenge NASA is facing as the ISS integrator is to ensure that engineering expertise and data are accessible in a timely fashion to ensure ongoing operations and mission success. Integrating international engineering teams requires definition and agreement on common processes and responsibilities, joint training and the emergence of a unique engineering team culture. ISS engineers face daunting logistical and political challenges regarding data sharing requirements. To assure systematic information sharing and anomaly resolution of integrated anomalies, the ISS Partners are developing multi-lateral engineering interface procedures. Data sharing and individual responsibility are key aspects of this plan. This paper describes several examples of successful multilateral anomaly resolution. These successes were used to form the framework of the Partner to Partner engineering interface procedures, and this paper describes those currently documented multilateral engineering processes. Furthermore, it addresses the challenges experienced to date, and the forward work expected in establishing a successful working relationship with Partners as their hardware is launched.

    2014-12-01

    The lumen depreciation and color shift of 17 different A lamps (15 LED, 1 CFL, 1 halogen) was monitored in the automated long-term test apparatus (ALTA) for more than 7,500 hours. Ten samples of each lamp model were tested, with measurements recorded on a weekly basis. The lamps were operated continuously at an ambient temperature of 45°C (-1°C). Importantly, the steady-state test conditions were not optimized for inducing catastrophic failure for any of the lamp technologies—to which thermal cycling is a strong contributor— and are not typical of normal use patterns—which usually include off periods where the lamp cools down. Further, the test conditions differ from those used in standardized long-term test methods (i.e., IES LM-80, IES LM-84), so the results should not be directly compared. On the other hand, the test conditions are similar to those used by ENERGY STAR (when elevated temperature testing is called for). Likewise, the conditions and assumptions used by manufacturers to generated lifetime claims may vary; the CALiPER long-term data is informative, but cannot necessarily be used to discredit manufacturer claims. The test method used for this investigation should be interpreted as one more focused on the long-term effects of elevated temperature operation, at an ambient temperature that is not uncommon in luminaires. On average, the lumen maintenance of the LED lamps monitored in the ALTA was better than benchmark lamps, but there was considerable variation from lamp model to lamp model. While three lamp models had average lumen maintenance above 99% at the end of the study period, two products had average lumen maintenance below 65%, constituting a parametric failure. These two products, along with a third, also exhibited substantial color shift, another form of parametric failure. While none of the LED lamps exhibited catastrophic failure—and all of the benchmarks did—the early degradation of performance is concerning, especially with a

    Soederberg, David; Weisbach, Henrik (Vattenfall Vindkraft AB, Stockholm (Sweden))

    2008-11-15

    This report aims to provide information of, and experiences from, service and maintenance of Lillgrund Offshore Wind Farm. The report deals with operation and maintenance (O and M) during construction, commissioning and the first three months of operation. Focus has been to describe the organization and cooperation between Vattenfall and Siemens. Experiences have been collected by interviews with representatives from Siemens and Vattenfall. The O and M strategy defined by Lillgrund's service and maintenance contract are based on a gradual take over of O and M. Siemens will be responsible for maintenance of Lillgrund during the first five years. During this five-year period, Vattenfall will build up its own maintenance organization for Lillgrund. The first three years, Vattenfall's technicians are supposed to form 30 % of the total number of maintenance technicians. The fourth and fifth year, the corresponding amount should be 50 %. During daytime, Lillgrund is operated locally. During nights and weekends, it is operated remotely by Vattenfall's operating centre in Esbjerg. The major O and M experience from Lillgrund is the need for good administrative and technical information systems. These systems should be implemented as soon as possible because of the large amounts of documentation that are created during the commissioning phase. The technical information systems must be able to present historic data of measurements in order to see trends and analyse faults

    The United States Department of Energy (DOE) awarded a grant to GL Garrad Hassan (GL GH) to investigate the logistics, opportunities, and costs associated with existing and emerging installation and operation and maintenance (O&M) activities at offshore wind projects as part of the DOE’s program to reduce barriers facing offshore wind project development in the United States (U.S.). This report (the Report) forms part of Subtopic 5.3 “Optimized Installation, Operation and Maintenance Strategies Study” which in turn is part of the “Removing Market Barriers in U.S. Offshore Wind” set of projects for the DOE. The purpose of Subtopic 5.3 is to aid and facilitate informed decision-making regarding installation and O&M during the development, installation, and operation of offshore wind projects in order to increase efficiency and reduce the levelized cost of energy (LCoE). Given the large area of U.S. territorial waters, the generally higher mean wind speeds offshore, and the proximity to the coast of many large U.S. cities, offshore wind power has the potential to become a significant contributor of energy to U.S. markets. However, for the U.S. to ensure that the development of offshore wind energy projects is carried out in an efficient and cost-effective manner, it is important to be cognizant of the current and emerging practices in both the domestic and international offshore wind energy industries. The U.S. can harness the experience gained globally and combine this with the skills and assets of an already sizeable onshore wind industry, as well as the resources of a mature offshore oil and gas industry, to develop a strong offshore wind sector. The work detailed in this report is aimed at assisting with that learning curve, particularly in terms of offshore specific installation and O&M activities. This Report and the Installation and O&M LCoE Analysis Tool, which were developed together by GL GH as part of this study, allow readers to identify, model

    Eight healthy horses premedicated with xylazine and induced with ketamine were used to evaluate sevoflurane in oxygen for maintenance of anaesthesia during elective exploratory laparotomy. After orotracheal intubation, horses were hoisted, placed in dorsal recumbency on a padded surgery table, and received sevoflurane in oxygen for maintenance of anaesthesia. The horses were allowed to breathe spontaneously until instrumented; then, they were mechanically ventilated to maintain the PaCO2 between 35 and 45 mmHg. Systolic (SAP), diastolic (DAP), and mean (MAP) arterial blood pressures, heart rate (HR), ECG, respiratory rate, an estimation of the saturation of haemoglobin with oxygen in peripheral arterial blood (S(p)O2), nasal temperature, end-tidal CO2(ET(CO2)), end-tidal sevoflurane (ET(SEVO)), and vaporiser concentration were recorded every 5 min post induction; arterial blood samples were obtained soon after induction, at 30 min after induction, and every hour thereafter until surgery was completed. Recovery data including times from the sevoflurane vaporiser being turned off to first movement, to sternal recumbency, and to standing, number of attempts to stand, and recovery score (between 1 = safe, smooth and 6 = stormy, major injury to horse) were collected. Analysis of variance was performed using physiological data collected over 195 min of anaesthesia, the longest time period during which all 8 horses were instrumented. Time effects (P<0.05) for HR, SAP, DAP, MAP, and nasal temperature were identified. Heart rate peaked at 45 min and declined over the course of the procedure. Arterial blood pressure generally decreased over time. Body temperature decreased over time. From 15 to 195 min mean ET(SEVO)concentration ranged from 2.0 to 3.3%, while mean vaporiser settings ranged from 3.7 to 5.5%. Three horses received intra-operative ketamine; all horses received dobutamine infusions; and 2 horses received intra-operative calcium-dextrose. Total anaesthesia time

  16. A review on nitrogen and organics removal mechanisms in subsurface flow constructed wetlands: dependency on environmental parameters, operating conditions and supporting media.

    Science.gov (United States)

    Saeed, Tanveer; Sun, Guangzhi

    2012-12-15

    With the unique advantages of lower operational and maintenance cost, the applications of subsurface flow constructed wetlands for the treatment of wastewater have been increasing rapidly throughout the world. The removal of nitrogen and organics by such systems has gained substantial attention in recent years. In subsurface flow wetlands, the removal of pollutants often relies on a diverse range of co-existing physical, chemical and biological routes, which are vitally dependent on numerous environmental and operational parameters. This paper provides a comprehensive review of wetland structures, classic and novel nitrogen and organics removal mechanisms along with the key environmental parameters and operational conditions that enhance removal in subsurface flow wetland systems. The critical exploration identifies the major environmental parameters such as: pH, DO, and temperature, operational factors i.e. organic carbon availability, loading, feed mode, retention time, recirculation, harvesting, and the complex role (of both parameters) on classical nitrogen and organics removal pathways. Subsequently, the necessity of further extensive research on such factors, for promoting novel nitrogen removal routes in wetland systems has also been highlighted. The expansion of the review on the influence of the unconventional wetland matrix indicates that, the structural differences and inherent properties of these media can support substantial nitrogen and organics removal from wastewater, under optimal operating conditions. Overall, the critical review illustrates the necessity of a profound knowledge on the complicated inter-relationship between nitrogen and organics removal routes, governing environmental and operational parameters, and wetland matrix for improving the treatment performances of subsurface flow wetlands.

    2016-01-01

    Full Text Available In high-rise residential buildings, the quality of facilities management services is significant to the normal operation of the facilities. Unfortunately, lack of concern towards building maintenance, especially preventive maintenance, happens in domestic housing industry in Malaysia. Majority of the maintenance operations of condominiums suffer from lack of planning, lack of proactive maintenance plan, and lack of proper implementation. Thus, this paper reviews the implementation of preventive maintenance strategy, routine maintenance in specific. An extensive review of literature published in 1987 to 2014 is performed for the purpose of this research. The publications are sourced from journal articles, conference proceedings and books. The literature analysis confirms that the routine maintenance of facilities and building services is vital and it can be influential towards the maintenance performance. Subsequently, a theoretical framework is developed, which shows the relationship between routine maintenance of building facilities & services and maintenance performance. The building facilities & services are divided into two categories. They are essential facilities & services that ensure the safety, health, habitability, and operability of buildings; while value-added facilities & services deal with property value, return on investment, and quality living of buildings. Based on the findings, a future research is proposed, which aims to identify the appropriate routine of maintenance for the facilities and services in high-rise residential buildings to improve the maintenance performance.

  4. The Role of Logistics in Practical Levelized Cost of Energy Reduction Implementation and Government Sponsored Cost Reduction Studies: Day and Night in Offshore Wind Operations and Maintenance Logistics

    Directory of Open Access Journals (Sweden)

    Thomas Poulsen

    2017-04-01

    Full Text Available This paper reveals that logistics make up at least 17% of annual operational expenditure costs for offshore wind farms. Annual operational expenditure is found to vary by a factor of 9.5, making its share of levelized cost of energy for offshore wind range from 13% to 57%. These are key findings of a 20-month research project targeting cost reduction initiatives for offshore wind systems. The findings reveal that cost-out measures are difficult to implement due to cultural differences. Implementation efforts are rendered by personnel located offshore in a harsh sea environment which is in stark contrast to the shore-based office personnel who develop studies directing cost reduction efforts. This paper details the company motivation to join industry-wide cost reduction initiatives. A business case for offshore wind operations and maintenance logistics yielding 1% savings in levelized cost of energy is included on how to expand working hours from daytime to also work at night.

  5. The Role of Mitochondria in the Activation/Maintenance of SOCE: Store-Operated Ca(2+) Entry and Mitochondria.

    Science.gov (United States)

    Spät, András; Szanda, Gergö

    2017-01-01

    Mitochondria extensively modify virtually all cellular Ca(2+) transport processes, and store-operated Ca(2+) entry (SOCE) is no exception to this rule. The interaction between SOCE and mitochondria is complex and reciprocal, substantially altering and, ultimately, fine-tuning both capacitative Ca(2+) influx and mitochondrial function. Mitochondria, owing to their considerable Ca(2+) accumulation ability, extensively buffer the cytosolic Ca(2+) in their vicinity. In turn, the accumulated ion is released back into the neighboring cytosol during net Ca(2+) efflux. Since store depletion itself and the successive SOCE are both Ca(2+)-regulated phenomena, mitochondrial Ca(2+) handling may have wide-ranging effects on capacitative Ca(2+) influx at any given time. In addition, mitochondria may also produce or consume soluble factors known to affect store-operated channels. On the other hand, Ca(2+) entering the cell during SOCE is sensed by mitochondria, and the ensuing mitochondrial Ca(2+) uptake boosts mitochondrial energy metabolism and, if Ca(2+) overload occurs, may even lead to apoptosis or cell death. In several cell types, mitochondria seem to be sterically excluded from the confined space that forms between the plasma membrane (PM) and endoplasmic reticulum (ER) during SOCE. This implies that high-Ca(2+) microdomains comparable to those observed between the ER and mitochondria do not form here. In the following chapter, the above aspects of the many-sided SOCE-mitochondrion interplay will be discussed in greater detail.

  9. Quantification of risk considering external events on the change of allowed outage time and the preventive maintenance during power operation

    Energy Technology Data Exchange (ETDEWEB)

    Kang, D. J.; Kim, K. Y.; Yang, J. E

    2001-03-01

    In this study, for the major safety systems of Ulchin Units 3/4, we quantify the risk on the change of AOT and the PM during power operation to identify the effects on the results of external events PSA when nuclear power plant changes such as allowed outage time are requested. The systems for which the risks on the change of allowed outage time are quantified are High Pressure Safety Injection System (HPSIS), Containment Spray System (CSS), and Emergency Diesel Generator (EDG). The systems for which the risks on the PM during power operation are Low Pressure Safety Injection System (LPSIS), CSS, EDG, Essential Service Water System (ESWS). Following conclusions can be obtained through this study: 1)The increase of core damage frequency ({delta}CDF) on the change of AOT and the conditional core damage probability (CCDP) on the on-line PM of each system are differently quantified according to the cases of considering only internal events or only external events. . 2)It is expected that the quantification of risk including internal and external events is advantageous for the licensee of NPP if the regulatory acceptance criteria for the technical specification changes are relatively set up. However, it is expected to be disadvantageous for the licensee if the acceptance criteria are absolutely set up. 3)It is expected that the conduction on the quantification of only a fire event is sufficient when the quantification of external events PSA model is required for the plant changes of Korea Standard NPPs. 4)It is expected that the quantification of the increase of core damage frequency and the incremental conditional core damage probability on technical specification changes are not needed if the quantification results of those considering only internal events are below regulatory acceptance criteria and the external events PSA results are not greatly affected by the system availability. However, it is expected that the quantification of risk considering external events

    In 2010, the Finnish Transport Agency launched a project to study the carbon footprint of the construction, use and maintenance of Finland's transport network infrastructure. This report presents the results of the second phase, where the carbon footprint was calculated for the coastal ports and fairways used for merchant shipping (part 1 of this report). In addition, the carbon footprint of traffic operating on the road and rail networks and on the coastal fairways was calculated (part 2 of this report). The carbon footprints of four Finnish coastal merchant shipping ports and the fairways leading into them were calculated during a 100-year period. Based on these four cases and statistics the rest of the coastal ports were categorised into four groups: passenger ports, unitized cargo ports, bulk ports and liquid bulk ports. Based on this categorisation the carbon footprint for the infrastructure of coastal merchant shipping was estimated. A carbon footprint tool was developed to enable the modelling of the impacts of different port and fairway planning parameters on the life-cycle emissions. The main source of emissions in the selected cases was the energy used during the use phase: the fuel used by the machinery or the electricity consumed during the operation of the port. In the construction of the examined ports and fairways, the materials used, their transportation and installation do not have a significant impact on the life-cycle emissions. The carbon footprint of Finland's coastal merchant shipping ports and fairways (35 ports and 3 230 km of fairways) during the 100-year period was estimated at 150 000 tCO{sub 2}/a. The emissions of ports vary between 1 900-15 000 tCO{sub 2}/a. The largest sources of emissions do not always originate from the use phase as in the selected cases. The emissions of construction and maintenance can be larger than of the use phase in ports that occupy a large area of land in relation to the amount of traffic flowing

    This final report elaborated for the Swiss Federal Office of Energy (SFOE) takes a look at the results of a project carried out to determine the costs for facility management, to estimate future cost development and to propose activities for the further reduction of the operation and maintenance costs of photovoltaic systems. Information on the cost situation was collected by literature study, as well as in interviews and surveys with photovoltaic (PV) experts and the owners of PV installations. The discussion of the results at a workshop with about 20 Swiss PV experts is noted. The results are presented and discussed. These show that operating costs per kWh decrease with the size of the PV system. Figures are quoted. The major part of the costs are quoted as being those for spare parts, especially for the inverter. The authors are of the opinion that, in future, costs for facility management will further decrease, as they are partly linked to capital and insurance costs. Potential for optimisation is said to exist in several areas of facility management such as, for example, in system monitoring and fast reaction in the case of malfunctions.

    For reservoir operation,maintaining a quasi-natural flow regime can benefit river ecosystems,but may sacrifice human interests.This study took the Qingshitan Reservoir in the Lijiang River as a case,and developed an optimization model to explore a trade-off solution between social-economic interests and nature flow maintenance on a monthly base.The objective function considered irrigation,cruise navigation and water supply aspects.An index of flow alteration degree was proposed to measure the difference between the regulated discharge and the natural flow.The index was then used as an additional constraint in the model besides the conventional constraints on reservoir safety.During model solving,different criteria were applied to the index,representing various degrees of alteration of the natural flow regime in the river.Through the model,a relationship between social-economic interests and flow alteration degree was established.Finally,a trade-off solution of the reservoir operation was defined that led to a favorable social-economic benefit at an acceptable alteration of the natural flow.

    Petroleum and dairy operations are prominent sources of gas-phase organic compounds in California's San Joaquin Valley. It is essential to understand the emissions and air quality impacts of these relatively understudied sources, especially for oil/gas operations in light of increasing US production. Ground site measurements in Bakersfield and regional aircraft measurements of reactive gas-phase organic compounds and methane were part of the CalNex (California Research at the Nexus of Air Quality and Climate Change) project to determine the sources contributing to regional gas-phase organic carbon emissions. Using a combination of near-source and downwind data, we assess the composition and magnitude of emissions, and provide average source profiles. To examine the spatial distribution of emissions in the San Joaquin Valley, we developed a statistical modeling method using ground-based data and the FLEXPART-WRF transport and meteorological model. We present evidence for large sources of paraffinic hydrocarbons from petroleum operations and oxygenated compounds from dairy (and other cattle) operations. In addition to the small straight-chain alkanes typically associated with petroleum operations, we observed a wide range of branched and cyclic alkanes, most of which have limited previous in situ measurements or characterization in petroleum operation emissions. Observed dairy emissions were dominated by ethanol, methanol, acetic acid, and methane. Dairy operations were responsible for the vast majority of methane emissions in the San Joaquin Valley; observations of methane were well correlated with non-vehicular ethanol, and multiple assessments of the spatial distribution of emissions in the San Joaquin Valley highlight the dominance of dairy operations for methane emissions. The petroleum operations source profile was developed using the composition of non-methane hydrocarbons in unrefined natural gas associated with crude oil. The observed source profile is

    During the last four years of operations, low technical downtime has been one of the relevant records of the Paranal Observatory. From the beginning of the Very Large Telescope (VLT) project, European Southern Observatory (ESO) has considered the implementation of a proper maintenance strategy a fundamental point in order to ensure low technical down time and preserve the Observatory's assets. The implementation of the maintenance strategy was based on the following aspects: - Strong maintenance sense during the design stage. Line Replacement Unit (LRU) concept, standardization and modularity of the Observatory equipment - Creation of a dedicated team for Maintenance - The implementation of a Computerized Maintenance Management System After four operational years, the result of these aspects has exceeded the expectations; the Observatory has been operating with high availability under a sustainable strategy. The strengths of the maintenance strategy have been based on modern maintenance concepts applied by regular production companies, where any minute of down time involves high cost. The operation of the actual Paranal Maintenance System is based mainly on proactive activities, such as regular inspections, preventive maintenance (PM) and predictive maintenance (PdM) plans. Nevertheless, it has been necessary to implement a strong plan for corrective maintenance (CM). The Spare Parts Strategy has also been an important point linked to the Maintenance Strategy and CMMS implementation. At present, almost 4,000 items related to the Observatory spare parts are loaded into the CMMS database. Currently, we are studying the implementation of a Reliability Centered Maintenance (RCM) project in one of our critical systems The following document presents the actual status of the Paranal Maintenance Strategy and which have been the motivations to implement the established strategy.

These smolts were produced from the brood year (BY) 2004 egg source and included captive brood (40,982) and conventional (199,586) origin smolts that were all progeny of Lostine River spring Chinook salmon. Operation of the Lostine River adult monitoring and collection facility in 2006 began May 15th, the first Chinook was captured on June 14, 2006 and the last Chinook was captured on September 27, 2006. The weir and trap were removed on October 1, 2006. A total of 534 adult Chinook, including jacks, were captured during the season. The composition of the run included 205 natural origin fish and 329 hatchery supplementation fish. There were no identified 'stray' hatchery fish from other programs trapped. Of the fish captured, 33 natural and 120 hatchery supplementation adults were retained for broodstock and transported to LGH for holding and spawning and 397 adult Chinook were passed or transported above the weir to spawn naturally. In 2006, no hatchery origin adult Chinook were transported and out planted in the Wallowa River and Bear Creek to spawn in under seeded habitat. In order to meet egg take goals for the conventional portion of the program, a determination was made that approximately 147 adults were needed for broodstock. As a result 16 (8 males and 8 females) of the 153 fish collected for broodstock were returned to the Lostine River to spawn naturally. Females that were spawned and provided the brood source were made up of 12 natural females and 45 supplementation females. One of these females tested positive for high levels of Bacterial Kidney Disease and consequently this females eggs were destroyed. The remaining females produced a total of 241,372 eggs at fertilization. Eye-up was 85.47% which yielded a total of 206,309 conventional program eyed eggs. The fecundity averaged 4

  11. Controlling the mode of operation of organic transistors through side-chain engineering

    KAUST Repository

    Giovannitti, Alexander

    2016-10-11

    Electrolyte-gated organic transistors offer low bias operation facilitated by direct contact of the transistor channel with an electrolyte. Their operation mode is generally defined by the dimensionality of charge transport, where a field-effect transistor allows for electrostatic charge accumulation at the electrolyte/semiconductor interface, whereas an organic electrochemical transistor (OECT) facilitates penetration of ions into the bulk of the channel, considered a slow process, leading to volumetric doping and electronic transport. Conducting polymer OECTs allow for fast switching and high currents through incorporation of excess, hygroscopic ionic phases, but operate in depletion mode. Here, we show that the use of glycolated side chains on a thiophene backbone can result in accumulation mode OECTs with high currents, transconductance, and sharp subthreshold switching, while maintaining fast switching speeds. Compared with alkylated analogs of the same backbone, the triethylene glycol side chains shift the mode of operation of aqueous electrolyte-gated transistors from interfacial to bulk doping/transport and show complete and reversible electrochromism and high volumetric capacitance at low operating biases. We propose that the glycol side chains facilitate hydration and ion penetration, without compromising electronic mobility, and suggest that this synthetic approach can be used to guide the design of organic mixed conductors.

We have established an optimized model of the transmission line operation and maintenance with this method which has combined with evaluation matrix theory and opportunity cost theory and human resources optimization allocation based on the present transmission line operation and maintenance in a certain electric power enterprise. The validation examples of the transmission line operation and maintenance in this electric power enterprise show that this optimized model, which can realize the highest personal utilization rate and maximized profit of overall system, has advantages of not only rationality and effectiveness, but also a much higher efficiency of the transmission line operation and maintenance. It can be expected that this method will be of potential application value in various fields, such as transmission line operation and maintenance and college staff configuration.

    This work has been carried out while the author was visiting the Visual Psychophysics lab at the Center for Ophthalmic Research, Harvard Medical School. The general framework is the design of a wiring diagrams visualization system for maintenance operators in electric plants. This study concentrates on how knowledge and experimental techniques from visual attention can help this goal. From this standpoint, the visualization system must best exploit the human visual system abilities. As electronic databases containing all the diagrams will soon be available, it is important to think in advance the display techniques. Presently, maintenance operators favor working with paper printouts even where such databases are already available. The study shows why such an approach is valuable for the design of a display that fits the operator`s tasks. Beyond that, this work has been a mean to learn the experimental techniques of cognitive sciences in an applied frame. (authors). 9 figs., 5 annexes.

    This work has developed and demonstrated a simple method for comparison of operation and maintenance cost for various waste combustion techniques and plants. The principal of the method is to coarsely and initially divide cost into comparable posts. Post of specific interest is thereafter compared on a more detailed level. This procedure allows comparison with a modest consumption of time and effort. There is a lack of such comparison because of the effort needed to in detail compare the, often for each plant unique, selection of techniques and strategies. A consequence of the lack of comparisons is that success stories become invisible. The same can be said about common research needs. The demonstrated method visualizes the effects of various selections of techniques and strategies. It also points out bottlenecks for further improvement of the investigated units. The method has been simple to use and it is therefore considered as suitable to use in a larger investigation covering several waste combustion units. Thus, the project has accomplished its aims.

    A basic replicon of the naphthalene degradation plasmid pFME5 (80 kb, IncP-7) has been constructed and sequenced. The nucleotide sequence of pFME5mini is almost identical to replicons of the pND6-1 subgroup, which was separated based on the reA-oriV homology in our previous work. The basic replicon of pFME5 is capable of replication and stable maintenance exclusively in Pseudomonas species. An analysis of the deletion mutation indicated that, in contrast to the parWAB region, the parC gene is not essential for the stability of pFME5mini and can be a common feature of IncP-7 replicons. We revealed that par-defective mutants of pFME5mini were slowly eliminated from the bacterial population in a nonselective medium compared to their pCAR1-based counterparts. Designed primers specific to the repA and parC genes can be used to detect IncP-7 plasmids, while primers specific to two variants of parA can be used for intragroup classification.
