    Abstract In this 48-month pilot study, long-term impacts of copper:lead galvanic connections on lead release to water were assessed without confounding differences in pipe exposure prehistory or disturbances arising from cutting lead pipe. Lead release was tracked from three lead service line configurations, including (1) 100% lead, (2) traditional partial replacement with 50% copper upstream of 50% lead, and (3) 50% lead upstream of 50% copper as a function of flow rate, connection types, and sampling methodologies. Elevated lead from galvanic corrosion worsened with time, with 140% more lead release from configurations representing traditional partial replacement configurations at 14 months compared to earlier data in the first 8 months. Even when sampled consistently at moderate flow rate (8 LPM) and collecting all water passing through service lines, conditions representing traditional partial service line configurations were significantly worse (≈40%) when compared to 100% lead pipe. If sampled at a high flow rate (32 LPM) and collecting 2 L samples from service lines, 100% of samples collected from traditional partial replacement configurations exceeded thresholds posing an acute health risk versus a 0% risk for samples from 100% lead pipe. Temporary removal of lead accumulations near Pb:Cu junctions and lead deposits from other downstream plastic pipes reduced risk of partial replacements relative to that observed for 100% lead. When typical brass compression couplings were used to connect prepassivated lead pipes, lead release spiked up to 10 times higher, confirming prior concerns raised at bench and field scale regarding adverse impacts of crevices and service line disturbances on lead release. To quantify semirandom particulate lead release from service lines in future research, whole-house filters have many advantages compared to other approaches. PMID:26989344

    2015-01-01

    Water quality parameters affecting sodium silicate performance in partial lead service line replacements were examined using a fractional factorial experimental design and static pipe systems. An external copper wire was used to create a galvanic connection between a former lead service line and a new copper pipe. The pipe systems were filled with lab prepared water made to mimic real water quality. Water was changed on a three times per week basis. A 2(4-1) fractional factorial design was used to evaluate the impact of alkalinity (15 mg L(-1) or 250 mg L(-1) as CaCO3), nitrate (1 mg L(-1) or 7 mg L(-1) as N), natural organic matter (1 mg L(-1) or 7 mg L(-1) as dissolved organic carbon), and disinfectant type (1 mg L(-1) chlorine or 3 mg L(-1) monochloramine), resulting in eight treatment conditions. Fractional factorial analysis revealed that alkalinity, natural organic matter and monochloramine had a significant positive effect on galvanic current. Natural organic matter and monochloramine also had a significant positive effect with respect to both total and dissolved lead release. For the treatment conditions examined, 67-98% of the lead released through galvanic currents was stored as corrosion scales and predominantly comprised of particulate lead (96.1-99.9%) for all eight treatments. The use of monochloramine and the presence of natural organic matter (7 mg L(-1)) were not favourable for corrosion control in sodium silicate-treated partial lead service line replacements, although further studies would be required to characterize optimal water quality parameters for specific water quality types. For utilities operating with sodium silicate as a corrosion inhibitor, this work offers further evidence regarding the consideration of chlorine as a secondary disinfectant instead of monochloramine, as well as the value of controlling natural organic matter in distributed water.

    Lead service line replacement (LSLR) is an important strategy for reducing lead exposure via drinking water, but jurisdictional issues can sometimes interfere with full replacement of the lead line. The effects of full and partial LSLR on lead levels were assessed using 5 × 1-L sample profiles collected at more than 100 single-unit residences. Profiles comprised four sequential standing samples (L1-L4) and a free-flowing sample (L5) drawn after a 5 min flush of the outlet. At 45 sites with full lead service lines, 90th percentile lead levels in standing samples ranged from 16.4 to 44.5 μg L(-1) (L1 and L4, respectively). In the free-flowing sample (L5), 90th percentile lead was 9.8 μg L(-1). Within 3 days, full LSLR had reduced L3-L5 lead levels by more than 50%, and within 1 month, lead levels were significantly lower in every liter of the sample profile. Conversely, partial LSLR more than doubled premises plumbing (L1, L2) lead release in the short term and did not reduce L1, L2 lead release in the long term. Even 6 months after partial LSLR, 27% of first-draw lead levels were greater than 15 μg L(-1) (the U.S. EPA action level), compared with 13% pre-replacement. PMID:27337040

    2003-12-19

    The National Ignition Facility (NIF) is designed with its high value optical systems in cassettes called Line Replaceable Units (LRUs). Virtually all of the NIF's active components are assembled in one of the {approx}4000 electrical and optical LRUs that serve between two and eight of NIF's 192 laser beam lines. Many of these LRUs are optomechanical assemblies that are roughly the size of a telephone booth. The primary design challenges for this hardware include meeting stringent mechanical precision, stability and cleanliness requirements. Pre-production units of each LRU type have been fielded on the first bundle of NIF and used to demonstrate that NIF meets its performance objectives. This presentation provides an overview of the NIF LRUs, their design and production plans for building out the remaining NIF bundles.

  12. Consider FRP linings instead of replacing storage tank bottoms

    LeBleu, J.B. ); Hummel, B. )

    1995-03-01

    If a storage tank bottom is corroding quickly, it must either be replaced, or a thick-filmed, fiberglass reinforced plastic (FRP) lining must be applied to the existing tank bottom. Replacing a tank bottom can be a costly and time-consuming process. Proper selection and application of an FRP lining system with a 60 to 65-mil thickness can save time, money and prevent internal corrosion of the steel tank bottom for 10 to 20 years. Average corrosion rate of carbon steel storage tanks in crude oil service at ambient temperatures is more than 1 mil per year. Corrosion occurs even more quickly when a layer of water containing corrosive compounds such as salt and sediment settles to the bottom of a crude oil tank. Installing a thick fiber glass-reinforced lining system involves applying a primer, putty, catalyzed resin with a glass mat and a sealcoat. After the tank has been pumped dry and the surface properly prepared, the entire process takes substantially less than the downtime and costs associated with replacing the entire tank bottom. The paper describes the application of a FRP lining system, testing and metal repairs, and the use of catalyzed resin and glass mats.

  17. Valuing Insect Pollination Services with Cost of Replacement

    2008-01-01

    Value estimates of ecosystem goods and services are useful to justify the allocation of resources towards conservation, but inconclusive estimates risk unsustainable resource allocations. Here we present replacement costs as a more accurate value estimate of insect pollination as an ecosystem service, although this method could also be applied to other services. The importance of insect pollination to agriculture is unequivocal. However, whether this service is largely provided by wild pollinators (genuine ecosystem service) or managed pollinators (commercial service), and which of these requires immediate action amidst reports of pollinator decline, remains contested. If crop pollination is used to argue for biodiversity conservation, clear distinction should be made between values of managed- and wild pollination services. Current methods either under-estimate or over-estimate the pollination service value, and make use of criticised general insect and managed pollinator dependence factors. We apply the theoretical concept of ascribing a value to a service by calculating the cost to replace it, as a novel way of valuing wild and managed pollination services. Adjusted insect and managed pollinator dependence factors were used to estimate the cost of replacing insect- and managed pollination services for the Western Cape deciduous fruit industry of South Africa. Using pollen dusting and hand pollination as suitable replacements, we value pollination services significantly higher than current market prices for commercial pollination, although lower than traditional proportional estimates. The complexity associated with inclusive value estimation of pollination services required several defendable assumptions, but made estimates more inclusive than previous attempts. Consequently this study provides the basis for continued improvement in context specific pollination service value estimates. PMID:18781196

    To succeed under the value-based business model, hospitals and health systems require effective service line analytics that combine inpatient and outpatient data and that incorporate quality metrics for evaluating clinical operations. When developing a framework for collection, analysis, and dissemination of service line data, healthcare organizations should focus on five key aspects of effective service line analytics: Updated service line definitions. Ability to analyze and trend service line net patient revenues by payment source. Access to accurate service line cost information across multiple dimensions with drill-through capabilities. Ability to redesign key reports based on changing requirements. Clear assignment of accountability. PMID:26548137

    1999-03-08

    In the National Ignition Facility (NIF), currently under design and construction at Lawrence Livermore National Laboratory (LLNL), 192 high-power laser beamlines incorporating over 8,000 large optics, are focused onto a target smaller than a dime. The actual laser path will be contained within the Laser Target Area Building (LTAB), but the smaller adjacent building, the Optics Assembly Building, is where the optic modules are assembled and aligned. After the optics are finished in the OAB they must be transported and installed into the LTAB. While this is done strict cleanliness and handling conditions must be maintained. To maximize the efficiency of this process the optics are assembled into Line Replaceable Units (LRUs), which typically consist of a mechanical housing, laser optics, utilities, actuators and kinematic mounts. In this paper the Optical Transport and Material Handling designs that will be used to deliver the LRUs into the NIF laser bays are presented. Five types of delivery systems have been developed to deliver the LRUs to their locations in the LTAB. They are top loading, bottom loading, side loading, switchyard loading and target area loading. The first three operate in the laser bay of the LTAB and are transported between the OAB and the LTAB by the Laser Bay Transport System (LBTS). All delivery systems must maintain each optical LRU assemblies' specified shock, vibration, cleanliness, and environmental requirements. The design for each delivery system must take into consideration the cleanliness, functionality and alignment of the LRUs while maximizing commonality in order to meet the beamline installation schedule. This paper focuses on the design challenges of the bottom, side and top loading delivery systems and especially on how commonality among these varied systems is achieved.

    Clark, Andrew G.; Bundgaard, Jørgen

    1984-01-01

    Selection components analysis was performed in lines of Drosophila melanogaster at three times during substitution backcrossing. The initial two lines were inbred isofemale lines from natural populations in California, and one had the spread wing mutation eagle. The selection components analysis revealed aspects of the genetic structure of the determinants of fitness by demonstrating changes in the marginal fitnesses of the eagle locus. Differences among backgrounds essentially disappeared by the 20th generation of backcrossing, suggesting that the previously observed differences were attributable to linkage disequilibrium. The method of bootstrapping was used as a novel means of determining statistical confidence in selection components. PMID:17246226

  17. 222-S radioactive liquid waste line replacement and 219-S secondary containment upgrade, Hanford Site, Richland, Washington

    SciTech Connect

    1995-01-01

    The U.S. Department of Energy (DOE) is proposing to: (1) replace the 222-S Laboratory (222-S) radioactive liquid waste drain lines to the 219-S Waste Handling Facility (219-S); (2) upgrade 219-S by replacing or upgrading the waste storage tanks and providing secondary containment and seismic restraints to the concrete cells which house the tanks; and (3) replace the transfer lines from 219-S to the 241-SY Tank Farm. This environmental assessment (EA) has been prepared in compliance with the National Environmental Policy Act (NEPA) of 1969, as amended, the Council on Environmental Quality Regulations for Implementing the Procedural Provisions of NEPA (40 Code of Federal Regulations [CFR] 1500-1508), and the DOE Implementing Procedures for NEPA (10 CFR 1021). 222-S is used to perform analytical services on radioactive samples in support of the Tank Waste Remediation System and Hanford Site environmental restoration programs. Activities conducted at 222-S include decontamination of analytical processing and support equipment and disposal of nonarchived radioactive samples. These activities generate low-level liquid mixed waste. The liquid mixed waste is drained through pipelines in the 222-S service tunnels and underground concrete encasements, to two of three tanks in 219-S, where it is accumulated. 219-S is a treatment, storage, and/or disposal (TSD) unit, and is therefore required to meet Washington Administrative Code (WAC) 173-303, Dangerous Waste Regulations, and the associated requirements for secondary containment and leak detection. The service tunnels are periodically inspected by workers and decontaminated as necessary to maintain as low as reasonably achievable (ALARA) radiation levels. Although no contamination is reaching the environment from the service tunnels, the risk of worker exposure is present and could increase. 222-S is expected to remain in use for at least the next 30 years to serve the Hanford Site environmental cleanup mission.

    This report describes the current financial, technical and medical status of nephrology, dialysis and renal transplant services in these countries with the hope of helping our colleagues there to upgrade their standards of care. The general impression is that physicians as well as administrators in these countries are eager to improve conditions of patient care despite a disastrous economical climate. Our view is that we can help by providing literature, textbooks, journals, travel funds, by offering visiting fellowships to individual physicians, and by forming partnerships between nephrology centres.

  15. Incidence of joint replacement among active component service members, U.S. Armed Forces, 2004-2014.

    PubMed

    Daniele, Denise O; Taubman, Stephen B; Clark, Leslie L

    2015-05-01

    In the U.S., joint replacements have become more common and the average age of individuals who undergo joint replacements has decreased. Joint replacements among active component service members increased 10.5% during 2004-2009, then 61.9% during 2009-2014. Knees and hips were the most frequently replaced joints among service members. During the surveillance period (and particularly after 2009), incidence rates increased in each age group of service members 30 years or older. Relative to their respective counterparts, rates of joint replacement overall--and of the hip and knee specifically--were higher among service members who were black, non-Hispanic; officers; and healthcare workers. One year after joint replacement, 18.2% had retired; 5.2% had been medically disqualified from service; 6.3% had otherwise left service; and 70.3% were still in service. By 2 years post-joint replacement, 30.2% had retired; 13.0% had been medically disqualified; 10.0% had otherwise left service; and 46.8% were still in service. Service members aged 30-44 years were the most likely to remain in service post-joint replacement. Given the increases in the frequency of joint replacement among younger service members, the number of service members who remain in service post-joint replacement may continue to increase.

    In January 1989, SAO established an on-line service to help astronomers prepare ROSAT proposals by providing access to the preliminary source list from the ``Einstein Observatory Catalog of IPC X-ray Sources''. In the intervening years, we have updated the source list, added to the documentation, included many more Einstein databases as well as a number of tables from other wavebands, provided access to images for downloading from all of the Einstein CDROMs, and installed new software for more sophisticated filtering and retrieval. Although we have improved the functionality and made significant additions to the databases, we still maintain a simple menu interface accessible from any type of terminal. EOLS provides all of our databases to the NASA Astrophysics Data System (ADS) and our documents which describe each table are thus written in the ADS format. In conjunction with the IAU working group on Archiving and Data Bases for Radio Astronomy, EOLS serves as an experimental platform for on-line access to the radio source lists collected by one of us (H.A.). The number of these entries exceeds half a million.

    One purpose of our research is the investigation of the effectiveness and expressiveness of AdaPT(1), a set of language extensions to Ada 83, for distributed systems. As a part of that effort, we are now investigating the subject of replacing, e.g., upgrading, software modules while the software system remains in operation. The AdaPT language extension provide a good basis for this investigation for several reasons: (1) they include the concept of specific, self-contained program modules which can be manipulated; (2) support for program configuration is included in the language; and (3) although the discussion will be in terms of the AdaPT language, the AdaPT to Ada 83 conversion methodology being developed as another part of this project will provide a basis for the application of our findings to Ada 83 systems. The purpose of this investigation is to explore the basic mechanisms to the replacement process. Thus, while replacement in the presence of real-time deadlines, heterogeneous systems, and unreliable networks is certainly a topic of interest, we will first gain an understanding of the basic processes in the absence of such concerns. The extension of the replacement process to more complex situations can be made later. This report will establish an overview of the on-line upgrade problem, and present a taxonomy of the various aspects of the replacement process.

    Context Young adult smokers have the highest smoking prevalence of all US age groups but are least likely to use evidence-based cessation counseling or medication to quit. Objective Use and effectiveness of nicotine patch was explored in a randomized trial evaluating smoking cessation interventions with this population. Participants Smokers aged 18-30 (n=3,094) were recruited through online and off-line methods and from telephone quit lines and analyzed. Design Smokers were enrolled in a pretest-posttest trial, and randomized to one of three cessation services. Setting Trial delivering counseling services by self-help booklet, telephone quit line or online expert system in the 48 continental United States. Intervention Smokers could request a free two-week course of nicotine replacement therapy (NRT) patches from the project. Main Outcome Measure Follow-up surveys at 12-week and 26-weeks assessed smoking abstinence, use of NRT, counseling, and other cessation medications, and smoking-related variables. Results Overall, 69.0% of smokers reported using NRT (M=3.2 weeks) at 12-weeks and 74.8% (M=3.3 weeks) at 26-weeks. More smokers who were sent the free nicotine patches (n=1,695, 54.8%) reported using NRT than those who did not receive them (12-weeks: 84.3% v. 41.9%, p<.001; 26-weeks: 87.6% v. 51.1%, p<.001). NRT use was associated with greater smoking abstinence at 12-weeks (p<.001) and 26-weeks (p<.05), especially if used for more than two weeks (p<.001). Smokers assigned to a self-help booklet or cessation website and heavier smokers were most likely to use NRT (p<.05), while those reporting marijuana use and binge drinking used NRT less (p<.05). Conclusions Many young adults were willing to try NRT and it appeared to help them quit in the context of community-based cessation services. Strategies should be developed to make NRT available to this age group and support them in using it to prevent life-long smoking. PMID:24458316

    Building a radiology service line is a challenge. Beyond the science of imaging and pathophysiology of disease, there are a number of key elements and necessary actions-related to personnel, communication, and resources-that must be taken to make the service line successful and sustainable. Although there is no single best way to build an imaging-based service line, there are a number of essential components. The purpose of this article is to delineate these components and describe how ambitious radiologists may successfully build and sustain a radiology service line. PMID:26476845

    Bement, L. J.; Kayser, E. G.; Schimmel, M. L.

    1983-01-01

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

  15. Spectral Line-Shape Model to Replace the Voigt Profile in Spectroscopic Databases

    NASA Astrophysics Data System (ADS)

    Lisak, Daniel; Ngo, Ngoc Hoa; Tran, Ha; Hartmann, Jean-Michel

    2014-06-01

    The standard description of molecular line shapes in spectral databases and radiative transfer codes is based on the Voigt profile. It is well known that its simplified assumptions of absorber free motion and independence of collisional parameters from absorber velocity lead to systematic errors in analysis of experimental spectra, and retrieval of gas concentration. We demonstrate1,2 that the partially correlated quadratic speed-dependent hardcollision profile3. (pCqSDHCP) is a good candidate to replace the Voigt profile in the next generations of spectroscopic databases. This profile takes into account the following physical effects: the Doppler broadening, the pressure broadening and shifting of the line, the velocity-changing collisions, the speed-dependence of pressure broadening and shifting, and correlations between velocity- and phase/state-changing collisions. The speed-dependence of pressure broadening and shifting is incorporated into the pCqSDNGP in the so-called quadratic approximation. The velocity-changing collisions lead to the Dicke narrowing effect; however in many cases correlations between velocityand phase/state-changing collisions may lead to effective reduction of observed Dicke narrowing. The hard-collision model of velocity-changing collisions is also known as the Nelkin-Ghatak model or Rautian model. Applicability of the pCqSDHCP for different molecular systems was tested on calculated and experimental spectra of such molecules as H2, O2, CO2, H2O in a wide span of pressures. For all considered systems, pCqSDHCP is able to describe molecular spectra at least an order of magnitude better than the Voigt profile with all fitted parameters being linear with pressure. In the most cases pCqSDHCP can reproduce the reference spectra down to 0.2% or better, which fulfills the requirements of the most demanding remote-sensing applications. An important advantage of pCqSDHCP is that a fast algorithm for its computation was developedab4,5 and allows

    2002-01-01

    Los Alamos National Laboratory (LANL), as part of the stockpile stewardship mission, is developing the capability to manufacture replacement pits for the United States nuclear weapon stockpile. Part of this effort requires that the various manufacturing activities formerly performed at the Rocky Flats be reconstructed at LANL, modernized to improve operation, and re-certified for pit production. Part of this effort requires that new pyrochemical metal production facilities be installed in TA-55 to replace existing outdated equipment. The purpose of this effort is design, build/procure, assemble, cold test, and support installation activities for ten pyrochemical processing gloveboxes and processing support equipment for insertion into a selected PF-4 laboratory. Eight of the gloveboxes will be connected to a common trolley tunnel with a state-of-the-art automated transport system that can access each glovebox. Five of those gloveboxes will be designed to accommodate standard water-cooled pyrochemical processing furnaces with appropriate lift mechanisms for handling the furnace products and processing hardware. Another glovebox will be designed to accommodate an improved breaking press that will be designed/procured to break alpha metal up to a thickness of l-inch, eliminate introduction of hydraulic oil to the glovebox environment, provide appropriate shielding for prevention of glovebox damage due to shrapnel projectiles, and use interchangeable impact tools in order to be able to process both contaminated and clean metals with the same machine. In addition, a storage glovebox and a distillation glovebox (already developed) will be attached to the transport system. Two other gloveboxes, one accommodating two casting furnaces and another storage glovebox, will be installed in the laboratory independent of the transport system. A transfer system (trolley) will be incorporated to handle material flow between the pyrochemical furnace gloveboxes, the press glovebox

  18. On-line PWR RHR pump performance testing following motor and impeller replacement

    SciTech Connect

    DiMarzo, J.T.

    1996-12-01

    On-line maintenance and replacement of safety-related pumps requires the performance of an inservice test to determine and confirm the operational readiness of the pumps. In 1995, major maintenance was performed on two Pressurized Water Reactor (PWR) Residual Heat Removal (RHR) Pumps. A refurbished spare motor was overhauled with a new mechanical seal, new motor bearings and equipped with pump`s `B` impeller. The spare was installed into the `B` train. The motor had never been run in the system before. A pump performance test was developed to verify it`s operational readiness and determine the in-situ pump performance curve. Since the unit was operating, emphasis was placed on conducting a highly accurate pump performance test that would ensure that it satisfied the NSSS vendors accident analysis minimum acceptance curve. The design of the RHR System allowed testing of one train while the other was aligned for normal operation. A test flow path was established from the Refueling Water Storage Tank (RWST) through the pump (under test) and back to the RWST. This allowed staff to conduct a full flow range pump performance test. Each train was analyzed and an expression developed that included an error vector term for the TDH (ft), pressure (psig), and flow rate (gpm) using the variance error vector methodology. This method allowed the engineers to select a test instrumentation system that would yield accurate readings and minimal measurement errors, for data taken in the measurement of TDH (P,Q) versus Pump Flow Rate (Q). Test results for the `B` Train showed performance well in excess of the minimum required. The motor that was originally in the `B` train was similarly overhauled and equipped with `A` pump`s original impeller, re-installed in the `A` train, and tested. Analysis of the `A` train results indicate that the RHR pump`s performance was also well in excess of the vendors requirements.

    Experience with delivery of renal replacement therapy (RRT) in support of combat operations by the U.S. military has not been reported since the 1970s. We describe the tri-service military medical experience with RRT in support of Operation Iraqi Freedom. Through December 31, 2006, RRT was provided to 12 individuals inside the theater of operations. Navy medical personnel provided RRT to three patients (two U.S. active duty service members and one host nation individual) aboard the USNS Comfort, a mobile level 4 hospital. Dialysis was performed using conventional single-pass hemodialysis machines equipped with portable reverse osmosis systems. Army and Air Force medical personnel provided RRT to nine patients in theater (eight host nation patients and one U.S. active duty service member), using peritoneal dialysis and continuous renal replacement therapy (CRRT), not requiring trained renal nurses or technicians. Originally, U.S. military personnel with acute kidney injury (AKI) who were evacuated from theater to Landstuhl Regional Medical Center (LRMC), or those who developed AKI at LRMC were transferred to the German civilian medical system, if RRT was required. After creation of a rapid-response dialysis team and, later, positioning of a full-time active duty reserve nephrologist at LRMC, 16 patients received RRT at LRMC. None had required RRT in theater. Renal failure requiring RRT during combat operations remains an unusual but serious event, calling for flexibility in the provision of care. Notably, the Operation Iraqi Freedom experience has highlighted the needs of injured host nation patients with AKI and future military medical planning will need to account for their intratheater renal care.

    1997-01-01

    The NASA White Sands Test Facility (WSTF) is developing cleaning and verification processes to replace currently used chlorofluorocarbon-l13- (CFC-113-) based processes. The processes being evaluated include both aqueous- and solvent-based techniques. Replacement technologies are being investigated for aerospace hardware and for gauges and instrumentation. This paper includes the findings of investigations of aqueous cleaning and verification of aerospace hardware using known contaminants, such as hydraulic fluid and commonly used oils. The results correlate nonvolatile residue with CFC 113. The studies also include enhancements to aqueous sampling for organic and particulate contamination. Although aqueous alternatives have been identified for several processes, a need still exists for nonaqueous solvent cleaning, such as the cleaning and cleanliness verification of gauges used for oxygen service. The cleaning effectiveness of tetrachloroethylene (PCE), trichloroethylene (TCE), ethanol, hydrochlorofluorocarbon 225 (HCFC 225), HCFC 141b, HFE 7100(R), and Vertrel MCA(R) was evaluated using aerospace gauges and precision instruments and then compared to the cleaning effectiveness of CFC 113. Solvents considered for use in oxygen systems were also tested for oxygen compatibility using high-pressure oxygen autogenous ignition and liquid oxygen mechanical impact testing.

    Tobacco companies have begun to acquire pharmaceutical subsidiaries and recently started to market nicotine replacement therapies, such as Zonnic nicotine gum, in convenience stores. Conversely, tobacco companies are producing tobacco products such as tobacco chewing gum and lozenges that resemble pharmaceutical nicotine replacement products, including a nicotine pouch product that resembles snus pouches. This convergence of nicotine and tobacco product marketing has implications for regulation and tobacco cessation. PMID:27077338

    The Mount Zion Hospital (MZH) in San Francisco, Calif. is associated with the University of California at San Francisco (UCSF) medical center. These hospitals are approximately two miles apart. The UCSF radiology department supports specialty image reading for MZH daily. The major issue involved with this service is the access of patient images. Currently, the patient image access is through two ways: (1) inter-hospital travel, and (2) image delivery. Both methods are neither efficient nor economic. If patient images can be transferred from MZH to UCSF to be viewed in digital form in a reasonable time period, the issue of patient image accession can be resolved. This study attempts to use an available digital communication technology, a T-1 line, to verify this hypothesis. The study is centered on the comparison between the T-1 line and courier service with respect to cost and image delivery performance. This comparison study focuses on CT images with an emphasis on neuroradiology application.

  12. Staff planning for operating rooms with different surgical services lines.

    Villarreal, Monica C; Keskinocak, Pinar

    2016-06-01

    We present a two-phase model for a staff planning problem in a surgical department. We consider the setting where staff, in particular nurse circulators and surgical scrub technicians, are assigned to one of different service lines, and while they can be 'pooled' and temporally assigned to other service line if needed, these re-assignments should belimited. In Phase I, we decide on the number of staff hours to budget for each service line, considering policies limiting staff pooling and overtime, and different demand scenarios. In Phase II, we determine how these budgeted staff hours should be allocated across potential work days and shifts, given estimated staff requirements and shift-related scheduling restrictions. We propose a heuristic to speed the model's Phase II solution time. We implement the model using a hospital's surgical data and compare the model's results with the hospital's current practices. Using a simulation model for the surgical operations, we find that our two-phase model reduces the delays caused by staff unavailability as well as staff pooling, without increasing the workforce size. Finally, we briefly describe a decision-support tool we developed with the objective of fine-tuning staff planning decisions. PMID:25366968

    The snoMEN (snoRNA Modulator of gene ExpressioN) vector technology was developed from a human box C/D snoRNA, HBII-180C, which contains an internal sequence that can be manipulated to make it complementary to RNA targets, allowing knock-down of targeted genes. Here we have screened additional human nucleolar snoRNAs and assessed their application for gene specific knock-downs to improve the efficiency of snoMEN vectors. We identify and characterise a new snoMEN vector, termed 47snoMEN, that is derived from box C/D snoRNA U47, demonstrating its use for knock-down of both endogenous cellular proteins and G/YFP-fusion proteins. Using multiplex 47snoMEM vectors that co-express multiple 47snoMEN in a single transcript, each of which can target different sites in the same mRNA, we document >3-fold increase in knock-down efficiency when compared with the original HBII-180C based snoMEN. The multiplex 47snoMEM vector allowed the construction of human protein replacement cell lines with improved efficiency, including the establishment of novel GFP–HIF-1α replacement cells. Quantitative mass spectrometry analysis confirmed the enhanced efficiency and specificity of protein replacement using the 47snoMEN-PR vectors. The 47snoMEN vectors expand the potential applications for snoMEN technology in gene expression studies, target validation and gene therapy. PMID:27128805

    Localization as a technique to solve the complex and challenging problems besetting line-of-sight (LOS) and non-line-of-sight (NLOS) transmissions has recently attracted considerable attention in the wireless sensor network field. This paper proposes a strategy for eliminating NLOS localization errors during calculation of the location of mobile terminals (MTs) in unfamiliar indoor environments. In order to improve the hidden Markov model (HMM), we propose two modified algorithms, namely, modified HMM (M-HMM) and replacement modified HMM (RM-HMM). Further, a hybrid localization algorithm that combines HMM with an interacting multiple model (IMM) is proposed to represent the velocity of mobile nodes. This velocity model is divided into a high-speed and a low-speed model, which means the nodes move at different speeds following the same mobility pattern. Each moving node continually switches its state based on its probability. Consequently, to improve precision, each moving node uses the IMM model to integrate the results from the HMM and its modified forms. Simulation experiments conducted show that our proposed algorithms perform well in both distance estimation and coordinate calculation, with increasing accuracy of localization of the proposed algorithms in the order M-HMM, RM-HMM, and HMM + IMM. The simulations also show that the three algorithms are accurate, stable, and robust. PMID:26091395

  1. Substitute materials to replace asbestos in refinery-service gaskets and packings

    SciTech Connect

    Thomas, S.F.; McKillop, G.R.

    1986-05-26

    Refiners have been able to successfully replace asbestos in many packing and gasket applications. The changeover has been driven by health concerns, refusal of product liability insurance to suppliers, and supplier concern over long-term availability of asbestos. A great deal of purchasing and engineering effort is currently being expended to qualify and convert nonasbestos materials for gaskets and packings. The task has been complicated by a lack of objective performance criteria in existing industry standards. The majority of industry standards has specified the use of asbestos-based products because operating experience has shown they work. The specification criteria which do exist typically are valid for comparing competitive asbestos products only, and do not correlate well when applied to unrelated materials. The task of reliably and safely operating a refinery without asbestos-based gasketing and packing is progressing on three fronts: 1. Replacement with products based on materials such as flexible graphite and poly tetra fluoro ethylene (PTFE). Performance characteristics are well known, and sufficient historical operating data exist. The initial cost of these materials is typically higher than asbestos-based products. 2. Trials and replacement with ''new'' materials such as Aramid or glass-fiber-based sheet materials and braided packing, or mica/graphite-filled, spiral-wound gaskets. The performance characteristics of these materials are not well known in comparison to asbestos.

The 80-90-mm-thick working layer is made of type MKhGP-35 rammed chromite-clay compound. To protect the top of the side parts of the hearth from impacts, they are covered with a 40-mm-thick layer of rammed MKhGP-35 compound. During operation of the furnace and heating of the billets, the rammed compound of the hearth is compacted and after 6-7 months of service waves up to 20-30 mm deep are formed on it from the action of the round billets. To avoid the condition in which the unloading machine is not able to take the heated billets from such a hearth, ramming compound is added to the depressions in the hearth through the charging door. The furnace temperature is brought up to the heating schedule and billets are charged. The rammed lining is completely replaced once every two or three years. The saving with such a method of repair of the worn rammed hearth during 2 years of operation of the rotary furnace is substantial.

  4. Specialty-service lines: salvos in the new medical arms race.

    PubMed

    Berenson, Robert A; Bodenheimer, Thomas; Pham, Hoangmai H

    2006-01-01

    Hospitals and physicians are developing and marketing discrete and profitable specialty-service lines. Although closely affiliated specialist physicians are central to hospitals' service-line products, other physicians compete directly with hospitals via physician-owned specialty facilities. Specialty-service lines may be provided in a variety of settings, both inside and outside traditional hospital walls. Thus far, the escalating battle between hospitals and physicians for control over specialty services has not affected hospital profitability. However, as the scope of care that can be safely performed in the outpatient arena expands, physician competition for control over specialty services may threaten hospitals' financial health.

    Replacing the two Mn{sup 2+} ions normally present in human Arginase I with Co{sup 2+} resulted in a significantly lowered K{sub M} value without a concomitant reduction in k{sub cat}. In addition, the pH dependence of the reaction was shifted from a pK{sub a} of 8.5 to a pK{sub a} of 7.5. The combination of these effects led to a 10-fold increase in overall catalytic activity (k{sub cat}/K{sub M}) at pH 7.4, close to the pH of human serum. Just as important for therapeutic applications, Co{sup 2+} substitution lead to significantly increased serum stability of the enzyme. Our data can be explained by direct coordination of L-Arg to one of the Co{sup 2+} ions during reaction, consistent with previously reported model studies. In vitro cytotoxicity experiments verified that the Co{sup 2+}-substituted human Arg I displays an approximately 12- to 15-fold lower IC{sub 50} value for the killing of human hepatocellular carcinoma and melanoma cell lines and thus constitutes a promising new candidate for the treatment of L-Arg auxotrophic tumors.

  17. Windampers help keep gallop-prone lines in service

    SciTech Connect

    Marks, J.

    1995-02-01

    Damping devices for eliminating galloping on transmission lines have found increasing support in the sleet belt of the midwest. In these areas, winter storms result in ice buildup in transmission lines, and in high winds the layer of ice acts like an airfoil, creating a lift force on conductors. If the force goes undamped, it may be amplified until galloping occurs, causing the lines to touch and trip out. Surveys show that galloping occurs in winds of about 25 mph, usually across flat terrain. Steel companies and the Denver Airport are some of the companies installing dampers on their own. There is a preference for the Windamper System because of its ease of installation. After looking at spoilers, pendulums, and dampers, dampers were preferred because the spoilers were made of plastic instead of metal which didn`t seem as reliable over the long term.

    2015-07-01

    This paper presents a solution to the bottleneck problem with dynamic sharing or leasing of service capacities. From this perspective the use of the proposed method as a parallel element in service capacities sharing is very important, because it enables minimization of the number of interfaces, and consequently of the number of leased lines, with a combination of two service systems with time-opposite peak loads. In this paper we present a new approach, methodology, models and algorithms which solve the problems of dynamic leasing and sharing of service capacities. PMID:25792516

  19. Seeking an optimal renal replacement therapy for the chronic kidney disease epidemic: the case for on-line hemodiafiltration.

    PubMed

    Gatti, Emanuele; Ronco, Claudio

    2011-01-01

    The prevalence of chronic kidney disease (CKD) can be expected to increase dramatically in the foreseeable future, with suggestions that it has already reached epidemic proportions. The inadequate supply of donor organs, aggravated by an aging patient population, necessitates provision of sustainable dialysis treatment modalities. These treatment modalities must not only be of established clinical efficacy and effectiveness, but must simultaneously circumvent any potential treatment disparities due to geographical, social or other concurring factors. Home therapies might represent a partial solution to the complex issue of seeking optimal strategies to cope with the CKD epidemic. However, self-care renal replacement therapy (RRT), such as peritoneal dialysis (PD) and home therapies, can only be applied to a limited portion of the CKD population. Consequently, in preparation for coping with this CKD epidemic, specific large-scale plans need to be made that involve optimization of treatments already in use for the majority of the population requiring RRT, e.g. hemodialysis (HD). Extracorporeal chronic HD relies heavily on technology for its clinical success. Like the choice of the treatment modality and the complete medical approach to CKD patient care, the particular selection of the various components of the extracorporeal circuit has a significant impact on the well-being and survival of the patients. We present a medical-technological assessment of how best to treat vast numbers of dialysis patients under the financial restraints that are predicted to become even more severe as CKD entrenches itself as a more 'permanent epidemic'. A treatment modality is proposed that optimally addresses--and resolves--the debilitating effects of uremia, as well as of key clinical conditions closely linked to it. This treatment modality successfully tackles the issues of patient well-being, efficacy, effectiveness, safety and patient-nursing staff convenience--all in relation to

  20. Evaluation of Hose in Hose Transfer Line Service Life for Hanford's Interim Stabilization Program

    TORRES, T.D.

    2000-08-24

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

  1. A simple and efficient method to identify replacements of P-lacZ by P-Gal4 lines allows obtaining Gal4 insertions in the bithorax complex of Drosophila.

    PubMed

    de Navas, Luis; Foronda, David; Suzanne, Magali; Sánchez-Herrero, Ernesto

    2006-11-01

    The functional replacement of one gene product by another one is a powerful method to study specificity in development and evolution. In Drosophila, the Gal4/UAS method has been used to analyze in vivo such functional substitutions. To this aim, Gal4 lines that inactivate a gene and reproduce its expression pattern are required, and they can be frequently obtained by replacing pre-existing P-lacZ lines with such characteristics. We have devised a new method to quickly identify replacements of P-lacZ lines by P-Gal4 lines, and applied it successfully to obtain Gal4 insertions in the Ultrabithorax and Abdominal-B Hox genes. We have used these lines to study the functional replacement of a Hox gene by another one. Our experiments confirm that the abdominal-A gene can replace Ultrabithorax in haltere development but that it cannot substitute for Abdominal-B in the formation of the genitalia. PMID:16971094

    2005-01-01

    Introduction Research is an essential tool in facing the challenges of scaling up interventions and improving access to services. As in many other countries, the translation of research evidence into drug policy action in Tanzania is often constrained by poor communication between researchers and policy decision-makers, individual perceptions or attitudes towards the drug and hesitation by some policy decision-makers to approve change when they anticipate possible undesirable repercussions should the policy change as proposed. Internationally, literature on the role of researchers on national antimalarial drug policy change is limited. Objectives To describe the (a) role of researchers in producing evidence that influenced the Tanzanian government replace chloroquine (CQ) with sulfadoxine-pyrimethamine (SP) as the first-line drug and the challenges faced in convincing policy-makers, general practitioners, pharmaceutical industry and the general public on the need for change (b) challenges ahead before a new drug combination treatment policy is introduced in Tanzania. Methods In-depth interviews were held with national-level policy-makers, malaria control programme managers, pharmaceutical officers, general medical practitioners, medical research library and publications officers, university academicians, heads of medical research institutions and district and regional medical officers. Additional data were obtained through a review of malaria drug policy documents and participant observations were also done. Results In year 2001, the Tanzanian Government officially changed its malaria treatment policy guidelines whereby CQ – the first-line drug for a long time was replaced with SP. This policy decision was supported by research evidence indicating parasite resistance to CQ and clinical CQ treatment failure rates to have reached intolerable levels as compared to SP and amodiaquine (AQ). Research also indicated that since SP was also facing rising resistance trend

  3. Information logistics: A production-line approach to information services

    NASA Technical Reports Server (NTRS)

    Adams, Dennis; Lee, Chee-Seng

    1991-01-01

    Logistics can be defined as the process of strategically managing the acquisition, movement, and storage of materials, parts, and finished inventory (and the related information flow) through the organization and its marketing channels in a cost effective manner. It is concerned with delivering the right product to the right customer in the right place at the right time. The logistics function is composed of inventory management, facilities management, communications unitization, transportation, materials management, and production scheduling. The relationship between logistics and information systems is clear. Systems such as Electronic Data Interchange (EDI), Point of Sale (POS) systems, and Just in Time (JIT) inventory management systems are important elements in the management of product development and delivery. With improved access to market demand figures, logisticians can decrease inventory sizes and better service customer demand. However, without accurate, timely information, little, if any, of this would be feasible in today's global markets. Information systems specialists can learn from logisticians. In a manner similar to logistics management, information logistics is concerned with the delivery of the right data, to the ring customer, at the right time. As such, information systems are integral components of the information logistics system charged with providing customers with accurate, timely, cost-effective, and useful information. Information logistics is a management style and is composed of elements similar to those associated with the traditional logistics activity: inventory management (data resource management), facilities management (distributed, centralized and decentralized information systems), communications (participative design and joint application development methodologies), unitization (input/output system design, i.e., packaging or formatting of the information), transportations (voice, data, image, and video communication systems

  5. Towards On-Line Services Based on a Holistic Analysis of Human Activities

    NASA Technical Reports Server (NTRS)

    Clancey, William J.

    2004-01-01

    Very often computer scientists view computerization of services in terms of the logistics of human-machine interaction, including establishing a contract, accessing records, and of course designing an interface. But this analysis often moves too quickly to tactical details, failing to frame the entire service in human terms, and not recognizing the mutual learning required to define and relate goals, constraints, and the personalized value of available services. In particular, on-line services that "computerize communication" can be improved by constructing an activity model of what the person is trying to do, not just filtering, comparing, and selling piece-meal services. For example, from the customer s perspective the task of an on-line travel service is not merely to establish confirmed reservations, but to have a complete travel plan, usually integrating many days of transportation, lodging, and recreation into a happy experience. The task of the travel agent is not merely "ticketing", but helping the customer understand what they want and providing services that will connect everything together in an enjoyable way.

    This study examines differences between Veterans with and without prior Veterans Health Administration service use who received a clinical referral from the Veterans' Crisis Line. Differences between groups were identified using data taken from 13,444 calls and medical records. Approximately 91% of Veterans had a history of service use and 9% did not. Callers with prior service use were older, had more mental health disorders, made in-person contact more quickly, and used more outpatient mental healthcare. Those without prior service use were younger, had more mental health problems, and presented for care later. Callers with suicide-related diagnoses had high rates of service contact. These groups represent different subpopulations with unique healthcare needs and practices. PMID:26649615

    Veterinary vaccines contribute to food security, interrupt zoonotic transmissions, and help to maintain overall health in livestock. Although vaccines are usually cost-effective, their adoption depends on a multitude of factors. Because poultry vaccines are usually given to birds with a short life span, very low production cost per dose is one important challenge. Other hurdles are to ensure a consistent and reliable supply of very large number of doses, and to have flexible production processes to accommodate a range of different pathogens and dosage requirements. Most poultry vaccines are currently being produced on primary avian cells derived from chicken or waterfowl embryos. This production system is associated with high costs, logistic complexities, rigid intervals between harvest and production, and supply limitations. We investigated whether the continuous cell lines Cairina retina and CR.pIX may provide a substrate independent of primary cell cultures or embryonated eggs. Viruses examined for replication in these cell lines are strains associated with, or contained in vaccines against egg drop syndrome, Marek's disease, Newcastle disease, avian influenza, infectious bursal disease and Derzsy's disease. Each of the tested viruses required the development of unique conditions for replication that are described here and can be used to generate material for in vivo efficacy studies and to accelerate transfer of the processes to larger production volumes.

  16. Novel and efficient 10B lined tubelet detector as a replacement for 3He neutron proportional counters

    NASA Astrophysics Data System (ADS)

    Tsorbatzoglou, Kyriakos; McKeag, Robert D.

    2011-10-01

    This paper presents a novel and robust proportional detector which addresses the well publicized shortage of 3He gas by using a 10B lining applied to a tubelet configuration. The advantage of the tubelet structure is that it yields a detector maintaining the form factor of a conventional 3He tube whilst achieving a sensitivity of up to 75% of a 3 atm 3He device. The design and fabrication of the tubelet detector is presented and discussed with test data comparing the new detector to existing 3He and BF 3 tubes. The application of the tubelet design to security and industrial applications including retro-fitting to existing portals and suitability for high integrity oil and gas installations is addressed.

    Accountable care is designed to manage the health of patients using a capitated cost model rather than fee for service. Pay for performance is an attempt to use quality and not service reduction as the way to decrease costs. Pathologists will have to demonstrate value to the system. This value will include (1) working with clinical colleagues to optimize testing protocols, (2) reducing unnecessary testing in both clinical and anatomic pathology, (3) guiding treatment by helping to personalize therapy, (4) designing laboratory information technology solutions that will promote and facilitate accurate, complete data mining, and (5) administering efficient cost-effective laboratories. The pathology service line was established to improve the efficiency of delivering pathology services and to provide more effective support of medical center programs. We have used this model effectively at the Montefiore Medical Center for the past 14 years. PMID:22333926

    Phthalate plasticizers such as di(2-ethylhexyl) phthalate (DEHP) are being phased out of many consumer products because of their endocrine disrupting properties and their ubiquitous presence in the environment. The concerns raised from the use of phthalates have prompted consumers, government, and industry to find alternative plasticizers that are safe, biodegradable, and have the versatility for multiple commercial applications. We examined the toxicogenomic profile of mono(2-ethylhexyl) phthalate (MEHP, the active metabolite of DEHP), the commercial plasticizer diisononyl cyclohexane-1,2-dicarboxylate (DINCH), and three recently proposed plasticizers: 1,4-butanediol dibenzoate (BDB), dioctyl succinate (DOS), and dioctyl maleate (DOM), using the immortalized TM4 Sertoli cell line. Results of gene expression studies revealed that DOS and BDB clustered with control samples while MEHP, DINCH and DOM were distributed far away from the control-DOS-BDB cluster, as determined by principle component analysis. While no significant changes in gene expression were found after treatment with BDB and DOS, treatment with MEHP, DINCH and DOM resulted in many differentially expressed genes. MEHP upregulated genes downstream of PPAR and targeted pathways of cholesterol biosynthesis without modulating the expression of PPAR's themselves. DOM upregulated genes involved in glutathione stress response, DNA repair, and cholesterol biosynthesis. Treatment with DINCH resulted in altered expression of a large number of genes involved in major signal transduction pathways including ERK/MAPK and Rho signalling. These data suggest DOS and BDB may be safer alternatives to DEHP/MEHP than DOM or the commercial alternative DINCH. PMID:26445464

  1. Product-line administration: a framework for redefining medical record department services.

    PubMed

    Postal, S N

    1990-06-01

    Product-line administration is a viable approach for managing medical records services in an environment that demands high quantity and quality service levels. Product-line administration directs medical record department team members to look outside of the department and seek input from the customers it is intended to serve. The feedback received may be alarming at first, as the current state of products usually reveals a true lack of customer input. As the planning, defining, managing, and marketing phases are implemented, the road will not be easy and rewards will be slow to come. Product-line administration does not provide quick fixes, but it does provide long-term problem resolution as products are refined and new products developed to meet customer needs and expectations. In addition to better meeting the needs of the department's external customers, the department's internal customers' needs and expectations will be addressed. The participative management approach will help nurture each team member's creativity. The team members will have the opportunity to reach their full potential while reaping the rewards and benefits of providing products and services that meet the needs and expectations of all department customers. The future of the health care industry promises more changes as the country moves toward some form of prospective payment in the ambulatory setting. Reactive management and the constant struggle to catch up can no longer be accepted as a management approach. It is imperative that the medical record department be viewed as a business with product lines composed of quality products. The planning, defining, managing, and marketing components of product-line administration afford responsiveness to the current situation and the development of quality products that will ensure that medical record departments are prepared for the future.

    As use of on-line searching services has progressed in libraries, requests on primary materials have increased much more than before. For the purpose of clarifying this trend and countermeasures against it a survey by questionnaire was conducted in 1985. The respondants from totally 112 libraries are as follows ; 60 industrial libraries, 41 academic libraries and 11 libraries of research institutes and laboratories. It was shown that industrial libraries have received more requests on primary materials mostly resulting from on-line searching while the requests have not increased remarkably in academic libraries. Regardless the type of libraries, almost all libraries can not fully meet the requests with their own collection so that industrial libraries have to rely on external information services and academic libraries utilize interlibrary loan system. Requests are sent via on-line from industrial libraries, and by mail from academic libraries. In fact, any-libraries are not likely to review their material-collecting policy. Therefore it is urgent to establish the system which enables use of external information services or interlibrary loan system more than ever.

    The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) maintains a (60)Co teletherapy source primarily for the calibration of therapy dosemeters. The source and encapsulating head were replaced in early 2010 with an Eldorado 78 head and new (60)Co source. In this article we present the results of ongoing accuracy and stability measurements since the replacement. A number of formal and informal indirect comparisons have been carried out with laboratories holding primary and secondary standards for (60)Co. ARPANSA chambers have also been calibrated at international primary standard laboratories allowing comparison of calibration coefficients and thus (60)Co absorbed dose standards. (60)Co calibration coefficients supplied by manufacturers of chambers were compared to those measured at the ARPANSA when this calibration was traceable to a primary standard. ARPANSA also participates in an annual international mailed dosimetry audit conducted by the International Atomic Energy Agency. The results thus far demonstrate that the absorbed doses to water delivered by the new ARPANSA (60)Co source are consistent with international doses within the stated uncertainties. PMID:25749989

    Environmental information for decision support must be user-focused, accurate, and actionable. As the deleterious impacts of a non-stationary climate system manifest themselves through loss of civil infrastructure, cultural, and natural resources, NOAA and other science agencies are restructuring their approach to decision support, moving from a climate perspectives-centric model to one that offers more nimble, granular, and timely product lines supporting a breadth of sectoral- and regionally-focused decisions. This talk outlines NOAA’s efforts to this end, including its framing of sectors and regions, its development of emerging product lines, and its reliance on technological advances to better disseminate information. Through its climate services efforts, NOAA’s climate data resources can be leveraged to support sound adaptation decision making for societal infrastructure development and in the stewardship of marine, ocean, coastal, and terrestrial natural resources.

    X80 grade high strength large diameter line pipe (UOE Pipe) for sour service have been studied. Increasing Mn content to provide strength of X80 increases HIC susceptibility due to center segregation of Mn in continuously cast slabs. The Mn content should be controlled less than 1.4% to maintain HIC resistance in the NACE TM0177 solution. The required strength can be obtained by addition of 0.5% Cr and accelerated controlled cooling after rolling. It has been clarified that Cr is very useful in providing high strength X70 without accelerating the center segregation of Mn. SSC resistance can be improved by controlling maximum hardness of weld metal lower than 230 Hv. Sour service X80 UOE pipes of two sizes were manufactured on large scales based on these experimental results. These pipes showed good low temperature toughness and HIC resistance in the NACE TM0177 solution.

    1999-11-01

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

  15. Developing Effective Continuous On-Line Monitoring Technologies to Manage Service Degradation of Nuclear Power Plants

    SciTech Connect

    Meyer, Ryan M.; Ramuhalli, Pradeep; Bond, Leonard J.; Cumblidge, Stephen E.

    2011-09-30

    Recently, there has been increased interest in using prognostics (i.e, remaining useful life (RUL) prediction) for managing and mitigating aging effects in service-degraded passive nuclear power reactor components. A vital part of this philosophy is the development of tools for detecting and monitoring service-induced degradation. Experience with in-service degradation has shown that rapidly-growing cracks, including several varieties of stress corrosion cracks (SCCs), can grow through a pipe in less than one fuel outage cycle after they initiate. Periodic inspection has limited effectiveness at detecting and managing such degradation requiring a more versatile monitoring philosophy. Acoustic emission testing (AET) and guided wave ultrasonic testing (GUT) are related technologies with potential for on-line monitoring applications. However, harsh operating conditions within NPPs inhibit the widespread implementation of both technologies. For AET, another hurdle is the attenuation of passive degradation signals as they travel though large components, relegating AET to targeted applications. GUT is further hindered by the complexity of GUT signatures limiting its application to the inspection of simple components. The development of sensors that are robust and inexpensive is key to expanding the use of AET and GUT for degradation monitoring in NPPs and improving overall effectiveness. Meanwhile, the effectiveness of AET and GUT in NPPs can be enhanced through thoughtful application of tandem AET-GUT techniques.

  16. A new service at the starting line - Direct broadcasting from satellites

    NASA Astrophysics Data System (ADS)

    Siocos, C. A.

    Aspects of the development of direct broadcast TV satellite systems (DBS) are reviewed, noting deficiencies, peculiarities, benefits, and regulatory considerations. The U.S. ended experimentation in DBS technology with the ATS-6 satellite, while other governments, such as Japan, Canada, and Australia continued tests. Russia orbited the Ekran DBS satellite for 714 MHz transmission to Siberian receivers in 1976. DBS can transmit to either community or individual antennas, and the ITU has decided that the international rules established for DBS systems shall permit any country wishing to introduce its own satellite be assured an orbit and frequencies for operations. The DBS systems may replace national broadcasting arrays, although twice a year, at equinox, DBS satellites will experience eclipse conditions which will require battery systems or temporary suspension of services. Problems such as spillover of a signal from one country to another are regarded as tolerable so long as it cannot be avoided, but signals pirated by unauthorized receivers will pose difficulties for operators of pay-television equipment.

    Whereas there is evidence that mixed-species approaches to production forestry in general can provide positive outcomes relative to monocultures, it is less clear to what extent multiple benefits can be derived from specific mixed-species alternatives. To provide such insights requires evaluations of an encompassing suite of ecosystem services, biodiversity, and forest management considerations provided by specific mixtures and monocultures within a region. Here, we conduct such an assessment in Sweden by contrasting even-aged Norway spruce (Picea abies)-dominated stands, with mixed-species stands of spruce and birch (Betula pendula or B. pubescens), or spruce and Scots pine (Pinus sylvestris). By synthesizing the available evidence, we identify positive outcomes from mixtures including increased biodiversity, water quality, esthetic and recreational values, as well as reduced stand vulnerability to pest and pathogen damage. However, some uncertainties and risks were projected to increase, highlighting the importance of conducting comprehensive interdisciplinary evaluations when assessing the pros and cons of mixtures.

    NewYork-Presbyterian Hospital is the result of the 1998 merger of two large New York City academic medical centers, the former New York and Presbyterian Hospitals, and is affiliated with two independent medical schools, the Columbia University College of Physicians and Surgeons and the Joan and Sanford J. Weill Medical College of Cornell University. At the time of the merger, the hospital faced a number of significant challenges, chief among them the clinical integration of the two medical centers. Size, separate medical schools, geography, and different histories and cultures all presented barriers to collaboration. To bring about the needed clinical alignment, the hospital turned to service lines as a way to realize the benefits of clinical integration without forcing the consolidation of departments. In this article, members of the hospital's senior management review the thinking behind the hospital's use of the service lines, their development and operation, and the significant, positive effects they have had on volume, clinical quality, clinical efficiency, best practices, and revenue management. They discuss how the service lines were used to bring together the two clinical cultures, the impact they have had on the way the hospital is operated and managed, and why service lines have worked at NewYork-Presbyterian in contrast to other hospitals that tried and abandoned them. Service lines play an increasingly central role in the hospital's clinical and business strategies, and are being extended into the NewYork-Presbyterian health care system. PMID:14604869

  5. Effects of Heat Treatments on the On-Line Service Life of a Press Die Manufactured by W-Edm

    NASA Astrophysics Data System (ADS)

    Choi, Kye-Kwang; Lee, Yong-Shin

    Effects of heat treatments on the on-line service life of a press die manufactured by W-EDM are studied. In this work, four manufacturing processes for a press die are considered: (1) milling and then grinding, (2) wire-cut electric discharge machining (W-EDM), (3) low temperature heat treatment after W-EDM, and (4) high temperature heat treatment after W-EDM. On-line punching experiments for an automobile part of BL646-chain are performed. The amount of wear of the die and punch, roll-over and burnish depth in the punched chain are measured every 1,000 strokes. Overall productivities are carefully compared. Finally, it is concluded that heat treatment after W-EDM for a press die can enhance its on-line service life. Especially, high temperature heat treatment after W-EDM is very attractive as a fast and cheap manufacturing method for a press die.

    2014-01-01

    The deinstitutionalization movement in Canada began in the 1960s. It is defined as the process of discharging chronic mental health patients into the community in order for them to receive care from community mental health services. The deinstitutionalization movement is failing in Canada at this time for two main reasons: (1) the provinces' community mental health programs lack integration; and (2) the negative stigma attached to mental illness is still present in the community. This article will discuss ways to ensure the integration of first-line mental health services and the elimination of stigma through organizational and systemic changes in Canada. PMID:25906464

    2007-01-01

    As more protein structures are solved, the likelihood that current structural investigations will involve proteins for which there exists no homologous structure continually decreases. The extraction of phase information from diffraction experiments is one of several great barriers that crystallographers must overcome on the path to structure solution. One means to overcome this obstacle, the technique of molecular replacement, uses the structural similarity between proteins with similar sequences to give a good first estimate of the phases for the diffraction data of the protein of interest. The programs that execute this technique currently come in many flavors, from traditional Patterson-based methods, to stochastic searches in greater than three dimensions, to maximum likelihood-enhanced molecular replacement, each possessing unique advantages that can shake loose a recalcitrant solution. As crystallographers aim to solve larger macromolecular complexes that more faithfully depict the actors in cellular events, having existing phase information for parts of those biological machines will reinforce the technological advancements in data collection and structure solution that have already produced mammoth structures like the ribosome, yielding an ever-clearer picture of the inner workings of biology.

    Detailed planning and organization has resulted in a smoothly executed six-year coating refurbishment program on 373 mi of live, high-pressure pipe in South Australia. Production of oil and gas in north-east South Australia. Production of oil and gas in north-east South Australia began in 1969 using pipe lines coated in single wrap polyethylene (PE) tape that, over time, has undergone severe degradation due to poor construction practices, severe soil stresses and, in some cases, high temperatures in transported fluids. In the late 70s, a massive expansion of natural gas production was planned. Given known problems with PE tapes, an alternative coating, flake-filled isophthalic polyester, was selected for high-temperature lines. When this subsequently failed, the polyester was replaced by fusion bonded epoxy (FBE). To date, only minor problems have been experienced with FBE. In the early 80s, about 373 mi were coated with suspect materials, either tape or polyester. In addition to corrosion leaks, there had been five failures due to stress corrosion cracking (SCC). Two of the most severe were in a 20-in. OD trunkline. Problems were somewhat exacerbated by the pipe lines being buried in some of the most corrosive soils in existence. To ameliorate the situation, a massive coating refurbishment program, the largest in the southern hemisphere, was undertaken. Because few of the lines initially were looped, it was decided to repair lines, where possible, live and operating at their normal 1,250 psi. Only concession was shut-down of lines with a history of SCC. In initiating a comprehensive refurbishment program, a strategy was developed to identify key points and objectives.

    The service line (SL) model has been proven to help shift health care toward value-based services, which is characterized by coordinated, multidisciplinary, high-quality, and cost-effective care. However, academic medical centers struggle with how to effectively set up SL structures that overcome the organizational and cultural challenges associated with simultaneously delivering the highest-value care for the patient and advancing the academic mission. In this article, the authors examine the evolution of UMass Memorial Health Care's heart and vascular service line (HVSL) from 2006 to 2011 and describe the impact on its success of multiple strategic decisions. These include key academic physician leadership recruitments and engagement via a matrixed governance and management model; development of multidisciplinary teams; empowerment of SL leadership through direct accountability and authority over programs and budgets; joint educational and training programs; incentives for academic achievement; and co-localization of faculty, personnel, and facilities. The authors also explore the barriers to success, including the need to overcome historical departmental-based silos, cultural and training differences among disciplines, confusion engendered by a matrixed reporting structure, and faculty's unfamiliarity with the financial and organizational skills required to operate a successful SL. Also described here is the impact that successful implementation of the SL has on creating high-quality services, increased profitability, and contribution to the financial stability and academic achievement of the academic medical center.

    Ways in which American online searchers can avail themselves of foreign services are discussed. It is noted that many European services offer the user an option in the choice of command protocols. Reasons why Americans generally do not use European online services include the fact that foreign databases tend to contain citations to foreign documents and many Americans do not read and speak any language other than English.

    Abstract Oral daily tenofovir/emtricitabine (Truvada) is approved in the United States for HIV preexposure prophylaxis (PrEP) but has generated controversy in the media and within HIV-affected communities. We conducted an online survey about PrEP-related knowledge, experience, opinions, and learning needs, and received 160 responses from service providers at Canadian AIDS Service Organizations. Respondents were cautiously optimistic about PrEP and 48.8% believed that PrEP warranted Health Canada approval. In multivariable logistic regression, support for PrEP approval was associated with more years working in HIV (odds ratio=1.89 per decade, 95% CI=1.10, 3.25), low baseline familiarity with PrEP (OR=3.24, 95% CI=1.01, 14.41), and knowing someone who had used PrEP (OR=4.39, 95% CI=1.28,15.08). Participants major concerns about PrEP were similar to those highlighted in other publications, and some issues specific to certain target populations were raised. Several participants (26.2%) had been asked about PrEP in the past year and 10.6% knew of one or more Canadian who had used PrEP. Despite clients' interest, most participants thought that they (60.6%) or their organization (63.1%) did not have enough current knowledge about PrEP, highlighting the need for further education on this novel HIV prevention strategy.

    Commercial sexual exploitation of women and girls through forced prostitution and sex-trafficking is a human rights and public health issue, with survivors facing complex mental health problems from trauma and violence. An international and domestic problem, the average age of recruitment into sex-trafficking is between 11 and 14 years old. Given its secrecy and brutality, such exploitation remains difficult to study, which results in a lack of knowledge related to trauma and how best to develop specific services that effectively engage and meet the unique needs of survivors. This qualitative research, using thematic analysis, explored the stories of trauma and its aftermath for commercially sexually exploited women as told by front-line service providers. Three themes emerged regarding the experience of sex-trafficking and its outcomes-Pimp Enculturation, Aftermath, and Healing the Wound-along with seven subthemes. These have important implications for all service and healthcare providers. PMID:23369118

    An improved filtered air exhaust system which may be continually operated during the replacement of the filters without the escape of unfiltered air is described. This is accomplished by hermetically sealing the box like filter containers in a rectangular tunnel with neoprene covered sponge rubber sealing rings coated with a silicone impregnated pneumatic grease. The tunnel through which the filters are pushed is normal to the exhaust air duct. A number of unused filters are in line behind the filters in use, and are moved by a hydraulic ram so that a fresh filter is positioned in the air duct. The used filter is pushed into a waiting receptacle and is suitably disposed. This device permits a rapid and safe replacement of a radiation contaminated filter without interruption to the normal flow of exhaust air.

    Physical and analytical aspects associated with the transport are presented. Included is a definition of the problems and difficulties imposed by the servicing of a typical solid cryogen system, as well as a discussion of the transport requirements and of the rationale which governed their solution. A successful detailed transport configuration is defined, and the application of established mathematics to the design approach is demonstrated. The significance of head pressure, pressure drop, line friction, heat leak, Reynolds number, and the fundamental equilibrium demands of pressure and temperature were examined as they relate to the achievement of liquid state flow. Performance predictions were made for the transport system, and several analytical quantities are tabulated. These data are analyzed and compared with measured and calculated results obtained while actually servicing a solid cryogen system during thermal/vacuum testing.

    The structure and aim of continuing medical education (CME) is shifting from the passive transmission of knowledge to a competency-based model focused on professional development. Self-directed learning is emerging as the foremost educational method for advancing competency-based CME. In a field marked by the constant expansion of knowledge, self-directed learning allows physicians to tailor their learning strategy to meet the information needs of practice. Point of care information services are innovative tools that provide health professionals with digested evidence at the front line to guide decision making. By mobilising self-directing learning to meet the information needs of clinicians at the bedside, point of care information services represent a promising platform for competency-based CME. Several points, however, must be considered to enhance the accessibility and development of these tools to improve competency-based CME and the quality of care. PMID:25655251

  13. Can consumer choice replace trust in the National Health Service in England? Towards developing an affective psychosocial conception of trust in health care.

    PubMed

    Fotaki, Marianna

    2014-11-01

    Trust has long been regarded as a vitally important aspect of the relationship between health service providers and patients. Recently, consumer choice has been increasingly advocated as a means of improving the quality and effectiveness of health service provision. However, it is uncertain how the increase of information necessary to allow users of health services to exercise choice, and the simultaneous introduction of markets in public health systems, will affect various dimensions of trust, and how changing relations of trust will impact upon patients and services. This article employs a theory-driven approach to investigate conceptual and material links between choice, trust and markets in health care in the context of the National Health Service in England. It also examines the implications of patient choice on systemic, organisational and interpersonal trust. The article is divided into two parts. The first argues that the shift to marketisation in public health services might lead to an over-reliance on rational-calculative aspects of trust at the expense of embodied, relational and social attributes. The second develops an alternative psychosocial conception of trust: it focuses on the central role of affect and accounts for the material and symbolic links between choice, trust and markets in health care.

    In order to prevent preferential corrosion in pipeline welds by means of chromium addition, a study was made on the effect of chromium content on the corrosion resistance of line pipe in a wet carbon dioxide environment. It was found that the addition of 0.6% chromium to the base material reduces the corrosion rate to half that of chromium-free steels without sacrificing field weldability and low-temperature toughness, and that the addition of 0.3% more chromium to the seam weld metal than in the base material prevents the preferential corrosion of the weld. The galvanic current between the base material and the weld metal was proved to be responsible for the preferential corrosion of the weld. The chromium addition prevents the preferential corrosion though the formation of spinel-type corrosion products composed of (Fe,Cr){sub 3}O{sub 4} with high impedance. The UOE pipe manufactured on the basis of the above findings showed excellent low-temperature toughness and field weldability as well as good corrosion resistance in a wet carbon dioxide environment.

    Presence of bacteria in high levels in the water lines of dental units is well known. The extent of this problem is however less well studied.This study was conducted to evaluate the water quality of all dental units within the Public Dental Health Service (Folktandvården, FTV) of the city of Göteborg, Sweden. 405 dental units in 35 clinics were tested.The evaluation included both "fast growing" (2 days incubation) and "slow growing" (7 days incubation) bacteria in 50 ml water sample from the units. The presence of potential pathogens, e.g., coliforms, Pseudomonas spp and Legionella pneumophila were also examined. Of the 405 dental units, 303 (75%) did not have acceptable (<100 CFU/ml fast growing and <5000 CFU/ml of slow growing bacteria) water quality. From 61 (15%) dental units in 13 clinics L. pneumophila were present but usually as few cells only. Immediate measures were introduced in Legionella positive units. No coliforms or Pseudomonas spp were detected. It can be concluded that the water in the dental units is generally not acceptable and does not fulfill drinking water standard. Many units have extremely high bacterial levels, which must be regarded as a risk for certain patient groups, e.g., immune-compromised and older patients. A general program for desinfection of all units of the Public Dental Health Service is needed. PMID:20162927

    2008-01-01

    Kennedy Space Center has used Aerocoat 7 (AR-7) to protect stainless-steel flex hoses at Launch Complex (LC-39) and hydraulic lines of the Mobile Launcher Platform (MLP) because it provides excellent corrosion protection in low-temperature applications. The Sovereign Company produced AR-7 exclusively for NASA but discontinued production because the coating released high levels of volatile organic compounds (VOCs) and had a significant environmental impact. The purpose of this project was to select and evaluate potential replacement coatings for AR-7 that would be more environmentally sound. The physical and mechanical properties of commercially available coatings were investigated through the Internet. The ideal coating would be fluid enough to penetrate the outer mesh of a stainless-steel flex hose and coat the inner hose, and flexible enough to withstand the movement of the hose, as well as the expansion and contraction of its metal caused by changes in temperature.

  2. Optimization of station battery replacement

    1994-08-01

    During a loss of ac power at a nuclear generating station (including diesel generators), batteries provide the source of power which is required to operate safety-related components. Because traditional lead-acid batteries have a qualified life of 20 years, the batteries must be replaced a minimum of once during a station's lifetime, twice if license extension is pursued, and more often depending on actual in-service dates and the results of surveillance tests. Replacement of batteries often occurs prior to 20 years as a result of systems changes caused by factors such as Station Blackout Regulations, control system upgrades, incremental load growth, and changes in the operating times of existing equipment. Many of these replacement decisions are based on the predictive capabilities of manual design basis calculations. The inherent conservatism of manual calculations may result in battery replacements occurring before actually required. Computerized analysis of batteries can aid in optimizing the timing of replacements as well as in interpreting service test data. Computerized analysis also provides large benefits in maintaining the as-configured load profile and corresponding design margins, while also providing the capability to quickly analyze proposed modifications and respond to internal and external audits.

  6. Chimney renovation versus chimney replacement

    Porthouse, R.A.

    1999-11-01

    Chimneys are an integral part of a fossil fueled generating station and perhaps one of the most commonly neglected and misunderstood structures at the plant. Structural damage caused by wind, earthquake, corrosive operating conditions, inadequate design, ever changing operating conditions, or years of neglect can render the structure unsafe and result in the need to perform major renovations or replace the entire chimney. The decision to renovate or replace an existing chimney is complex and should consider the following factors: (1) Age and condition of shell; (2) Type and condition of lining; (3) New operating conditions; (4) Cost of renovation vs replacement; (5) Unit outage time required; and (6) Cost for replacement power during outage. Information needed to make an informed decision regarding renovation or replacement, which most often involves several million dollars, can be best obtained from experienced chimney contractors and engineering specialists. This paper addresses four projects that utilized unique renovation techniques in lieu of partial or complete replacement of the structure.

    Mobil Oil's West Coast Pipe Line, as part of an ongoing program, has replaced sections of its crude oil pipe line that crosses Southern California's San Joaquin Valley. The significant aspect of the replacement project was the use of a new two-part coating process that has the ability to make cathodic protection more effective, while not deteriorating in service. Mobil's crude line extends from the company's San Joaquin Valley oil field in Kern County to the Torrance, Calif., refinery on the south side of Los Angeles. It crosses a variety of terrain including desert, foothills and urban development. Crude oil from the San Joaquin Valley is heavy and requires heating for efficient flow. Normal operating temperature is about 180{degrees}F. Due to moisture in the soil surrounding the hot line, the risk of corrosion is constant. Additionally, soil stress on such a line extending through the California hills inflicts damage on the protective coating. Under these conditions, coatings can soften, bake out and eventually become brittle. The ultimate result is separation from the pipe. The coating system employs a two-part process. Each of the two coatings are tailored to each other in a patented process, forming a chemical bond between the layers. This enhances the pipe protection both mechanically and electrically.

    RNase He1 from Hericium erinaceus, a member of the RNase T1 family, has high identity with RNase Po1 from Pleurotus ostreatus with complete conservation of the catalytic sequence. However, the optimal pH for RNase He1 activity is lower than that of RNase Po1, and the enzyme shows little inhibition of human tumor cell proliferation. Hence, to investigate the potential antitumor activity of recombinant RNase He1 and to possibly enhance its optimum pH, we generated RNase He1 mutants by replacing 12 Asn/Gln residues with Asp/Glu residues; the amino acid sequence of RNase Po1 was taken as reference. These mutants were then expressed in Escherichia coli. Using site-directed mutagenesis, we successfully modified the optimal pH for enzyme activity and generated a recombinant RNase He1 that inhibited the proliferation of cells in the human leukemia cell line. These properties are extremely important in the production of anticancer biologics that are based on RNase activity. PMID:25338779

  16. Short stem shoulder replacement

    PubMed Central

    Bell, Simon N.; Coghlan, Jennifer A.

    2014-01-01

    Context: It is agreed that it is important to anatomically reproduce the proximal humeral anatomy when performing a prosthetic shoulder replacement. This can be difficult with a long stemmed prosthesis, in particular if there is little relationship of the metaphysis to the humeral shaft. The ‘short stem’ prosthesis can deal with this problem. Aims: A prospective study assessed the results of total shoulder arthroplasty using a short stem humeral prosthesis, a ceramic humeral head, and a pegged cemented polyethylene glenoid. Materials and methods: Patients with primary shoulder osteoarthritis were recruited into this prospective trial and pre-operatively had the ASES, Constant, SPADI, and DASH scores recorded. The patients were clinically reviewed at the two weeks, eight weeks, one year, and two year mark with completion of a data form. Radiological evaluation was at the eight week, one year and two year follow-up. At the one and two year follow-up the satisfaction rating, the range of passive and active motion, Constant, ASES, SPADI, DASH and pain results were recorded and analysed with SPPS 20. Results: During the study period 97 short stem, ceramic head total shoulder replacements were carried out. At the time of follow-up 12 were two years from operation and 38 one year from operation. Active elevation was overall mean 160 degrees. Constant scores were 76 at 1 year, and 86 at 2 years, ASES 88 and 93, and satisfaction 96% and 98% respectively at one and 2 year follow up. There were no problems during insertion of the humeral prosthesis, or any radiolucent lines or movement of the prosthesis on later radiographs. Conclusion: The short stem prosthesis had no complications, and on follow up radiographs good bone fixation. These fairly short term clinical results were overall good. PMID:25258497

  14. Nashville Gas treads carefully to replace pipe

    SciTech Connect

    1997-06-01

    The private gas utility, Nashville Gas, was responsible for replacing damaged or inadequate 2- and 4-inch steel gas lines beneath Music City, USA. The line replacements required either size for size or upsizing. The first choice was directional drilling, which was quickly determined to be unpractical because of rocky soil conditions. The second option was open trenching. Undoubtedly, trenching would mean having to contend with angry residents and tourists, since gas lines ran beneath yards, mature trees, sidewalks, roadways, and railways. In addition to the negative social factors, trenching would require additional funds for substantial landscaping and pavement replacement. It at all possible, a no-dig alternative was desired. Nashville Gas found Grundomat piercing tools which create a bore, then pushes pipe back through it. These same tools can simultaneously pull in pipe. These tools were customized for the Nashville project.

    OBJECTIVE To determine whether implementation of a multifaceted intervention would significantly reduce the incidence of central line-associated bloodstream infections. DESIGN Prospective cohort collaborative. SETTING AND PARTICIPANTS Intensive care units of the Abu Dhabi Health Services Company hospitals in the Emirate of Abu Dhabi. INTERVENTIONS A bundled intervention consisting of 3 components was implemented as part of the program. It consisted of a multifaceted approach that targeted clinician use of evidence-based infection prevention recommendations, tools that supported the identification of local barriers to these practices, and implementation ideas to help ensure patients received the practices. Comprehensive unit-based safety teams were created to improve safety culture and teamwork. Finally, the measurement and feedback of monthly infection rate data to safety teams, senior leaders, and staff in participating intensive care units was encouraged. The main outcome measure was the quarterly rate of central line-associated bloodstream infections. RESULTS Eighteen intensive care units from 7 hospitals in Abu Dhabi implemented the program and achieved an overall 38% reduction in their central line-associated bloodstream infection rate, adjusted at the hospital and unit level. The number of units with a quarterly central line-associated bloodstream infection rate of less than 1 infection per 1,000 catheter-days increased by almost 40% between the baseline and postintervention periods. CONCLUSION A significant reduction in the global morbidity and mortality associated with central line-associated bloodstream infections is possible across intensive care units in disparate settings using a multifaceted intervention.

    Wide differences between the positional and photometric quality of astronomical data sets requires visual examination for accurate cross-identifications of sources between data sets. Given the tedium involved in these comparisons, astronomers need methods to perform rapid cross-comparisons. The On-Line Science Information Services (OASIS), a Java toolkit recently released by the IPAC Infrared Science Archive (IRSA), provides such capability. OASIS is a collection of services, designed to be run independently of each other, that access and integrate multiple image and catalog archives. Its first release provides access to IRAS, 2MASS, MSX, FIRST, and NVSS images, and is interoperable with NED and CDS. We describe its applicability to two projects that require bulk visual cross-identification: the NStars database, which serves quality-controlled data for all stellar, substellar, and planetary objects within 25 parsecs of the Sun; and identification of far-IR counterparts of 750 active galaxies measured by ROSAT.

    Dealing with corrosion has evolved from the early days of {und rust and replace} and now corrosion is effectively controlled by continuous chemical injection systems. A critical component of all continuous injection systems is the line. The line serves the purpose of transporting the chemical inhibitor downhole to the packer. Protecting the line during installation as well as its service life requires use of an encapsulation material to ensure integrity of the line and, therefore effectiveness of the entire system. Design criteria for the line and properties or encapsulation materials, including ECTFE fluoropolymer are discussed.

  16. Toxicology of chlorofluorocarbon replacements.

    PubMed Central

    Dekant, W

    1996-01-01

    Chlorofluorocarbons (CFCs) are stable in the atmosphere and may reach the stratosphere. They are cleaved by UV-radiation in the stratosphere to yield chlorine radicals, which are thought to interfere with the catalytic cycle of ozone formation and destruction and deplete stratospheric ozone concentrations. Due to potential adverse health effects of ozone depletion, chlorofluorocarbon replacements with much lower or absent ozone depleting potential are developed. The toxicology of these compounds that represent chlorofluorohydrocarbons (HCFCs) or fluorohydrocarbons (HFCs) has been intensively studied. All compounds investigated (1, 1-dichloro-1-fluoroethane [HCFC-141b], 1,1,1,2-tetrafluoroethane [HFC-134a], pentafluoroethane [HFC-125], 1-chloro- 1,2,2,2-tetrafluoroethane [HCFC-124], and 1,1-dichloro-2,2,2-trifluoroethane [HCFC-123]) show only a low potential for skin and eye irritation. Chronic adverse effects on the liver (HCFC-123) and the testes (HCFC-141b and HCFC-134a), including tumor formation, were observed in long-term inhalation studies in rodents using very high concentrations of these CFC replacements. All CFC replacements are, to varying extents, biotransformed in the organism, mainly by cytochrome P450-catalyzed oxidation of C-H bonds. The formed acyl halides are hydrolyzed to give excretable carboxylic acids; halogenated aldehydes that are formed may be further oxidized to halogenated carboxylic acids or reduced to halogenated alcohols, which are excretory metabolites in urine from rodents exposed experimentally to CFC replacements. The chronic toxicity of the CFC replacements studied is unlikely to be of relevance for humans exposed during production and application of CFC replacements. PMID:8722112

  20. Celotex (Registered) Replacement Study

    SciTech Connect

    Couture, S; Hafner, R

    2002-10-01

    The AL-R8 is the pit storage container in most widespread use at Pantex. The AL-R8 container family consists of standard 20-in.-diameter steel drums, 30 to 60 in. in height, with insulation inserts made of Celotex{reg_sign}--a fiberboard product made from processed sugar cane. Celotex is an acceptable material for inserts in many radioactive material shipping and storage containers. It is a good shock mitigator/insulator, does a fair job in fire protection (when oxygen is excluded), shielding, and criticality, and is inexpensive and easily available. However, the fiberboard absorbs water in humid environments which, when combined with chemical residues in the fiberboard, forms corrosive compounds that can shorten the life of the container and affect container contents. To protect the contents from this potentially damaging environment, the AL-R8 SI was developed to isolate the contents within a sealed stainless steel vessel inside the AL-R8. Although the SI protected the contents, corrosion studies indicated the SI lid bolts might corrode over time and surveillance showed that areas of the outer drum were still subject to corrosion. To address this potential problem, DOE/Albuquerque sponsored bolt and Celotex replacement studies. The bolt replacement study was assigned to Mason and Hanger's Pantex Facility and this Celotex Replacement Study to Lawrence Livermore National Laboratory. The Celotex Replacement Study evaluated options for replacing Celotex with a material that is chemically compatible with the AL-R8 SI container. The evaluation was limited to materials either used previously in nuclear materials shipping and storage containers or materials with known properties in a low-radiation environment. This limitation was set to ensure that the long-term aging effect on the new material is known a priori. Initial material evaluations narrowed the material choices to foam and cork. Although cork performed better than foam in some tests, cork was considered a less

  1. NARC Rayon Replacement Program

    NASA Technical Reports Server (NTRS)

    Wilson, Kenneth P.; McCool, Alex (Technical Monitor)

    2002-01-01

    This viewgraph presentation provides information on the search for a replacement product for the aerospace grade rayon formerly used in the reusable solid rocket motor (RSRM). The rayon used in RSRMs is no longer produced by the North American Rayon Corporation (NARC), though NASA has stockpiled rayon to be used until a suitable replacement is found to be used in the RSRM nozzle carbon cloth phenolic (CCP). The primary considerations are performance, process ability, variability, long term availability, and cost. The preference will be given to commercial off-the-shelf products as opposed to those which are custom made.

    Background Tooth replacement rate can be calculated in extinct animals by counting incremental lines of deposition in tooth dentin. Calculating this rate in several taxa allows for the study of the evolution of tooth replacement rate. Sauropod dinosaurs, the largest terrestrial animals that ever evolved, exhibited a diversity of tooth sizes and shapes, but little is known about their tooth replacement rates. Methodology/Principal Findings We present tooth replacement rate, formation time, crown volume, total dentition volume, and enamel thickness for two coexisting but distantly related and morphologically disparate sauropod dinosaurs Camarasaurus and Diplodocus. Individual tooth formation time was determined by counting daily incremental lines in dentin. Tooth replacement rate is calculated as the difference between the number of days recorded in successive replacement teeth. Each tooth family in Camarasaurus has a maximum of three replacement teeth, whereas each Diplodocus tooth family has up to five. Tooth formation times are about 1.7 times longer in Camarasaurus than in Diplodocus (315 vs. 185 days). Average tooth replacement rate in Camarasaurus is about one tooth every 62 days versus about one tooth every 35 days in Diplodocus. Despite slower tooth replacement rates in Camarasaurus, the volumetric rate of Camarasaurus tooth replacement is 10 times faster than in Diplodocus because of its substantially greater tooth volumes. A novel method to estimate replacement rate was developed and applied to several other sauropodomorphs that we were not able to thin section. Conclusions/Significance Differences in tooth replacement rate among sauropodomorphs likely reflect disparate feeding strategies and/or food choices, which would have facilitated the coexistence of these gigantic herbivores in one ecosystem. Early neosauropods are characterized by high tooth replacement rates (despite their large tooth size), and derived titanosaurs and diplodocoids independently

    During the last few years, due to medical and surgical evolution, patients with increasingly severe diseases causing multiorgan dysfunction are frequently admitted to intensive care units. Therapeutic options, when organ failure occurs, are frequently nonspecific and mostly directed towards supporting vital function. In these scenarios, the kidneys are almost always involved and, therefore, renal replacement therapies have become a common routine practice in critically ill patients with acute kidney injury. Recent technological improvement has led to the production of safe, versatile and efficient dialysis machines. In addition, emerging evidence may allow better individualization of treatment with tailored prescription depending on the patients' clinical picture (e.g. sepsis, fluid overload, pediatric). The aim of the present review is to give a general overview of current practice in renal replacement therapies for critically ill patients. The main clinical aspects, including dose prescription, modality of dialysis delivery, anticoagulation strategies and timing will be addressed. In addition, some technical issues on physical principles governing blood purification, filters characteristics, and vascular access, will be covered. Finally, a section on current standard nomenclature of renal replacement therapy is devoted to clarify the "Tower of Babel" of critical care nephrology. PMID:26918174

  7. Thyroid hormone replacement therapy.

    PubMed

    Wiersinga, W M

    2001-01-01

    Thyroid hormone replacement has been used for more than 100 years in the treatment of hypothyroidism, and there is no doubt about its overall efficacy. Desiccated thyroid contains both thyroxine (T(4)) and triiodothyronine (T(3)); serum T(3) frequently rises to supranormal values in the absorption phase, associated with palpitations. Liothyronine (T(3)) has the same drawback and requires twice-daily administration in view of its short half-life. Synthetic levothyroxine (L-T(4)) has many advantages: in view of its long half-life, once-daily administration suffices, the occasional missing of a tablet causes no harm, and the extrathyroidal conversion of T(4) into T(3) (normally providing 80% of the daily T(3) production rate) remains fully operative, which may have some protective value during illness. Consequently, L-T(4) is nowadays preferred, and its long-term use is not associated with excess mortality. The mean T(4) dose required to normalize serum thyroid stimulating hormone (TSH) is 1.6 microg/kg per day, giving rise to serum free T(4) (fT(4)) concentrations that are slightly elevated or in the upper half of the normal reference range. The higher fT(4) values are probably due to the need to generate from T(4) the 20% of the daily T(3) production rate that otherwise is derived from the thyroid gland itself. The daily maintenance dose of T(4) varies widely between 75 and 250 microg. Assessment of the appropriate T(4) dose is by assay of TSH and fT(4), preferably in a blood sample taken before ingestion of the subsequent T(4) tablet. Dose adjustments can be necessary in pregnancy and when medications are used that are known to interfere with the absorption or metabolism of T(4). A new equilibrium is reached after approximately 6 weeks, implying that laboratory tests should not be done earlier. With a stable maintenance dose, an annual check-up usually suffices. Accumulated experience with L-T(4) replacement has identified some areas of concern. First, the

    Renal replacement therapy (RRT) is a cornerstone in the clinical management of patients with acute kidney injury. Results from different studies agree that early renal support therapy (aimed to support the residual kidney function during early phases of organ dysfunction) may reduce mortality with respect to late RRT (aimed to substitute the complete loss of function during the advanced kidney insufficiency). Although it seems plausible that a timely initiation of RRT may be associated with improved renal and nonrenal outcomes in these patients, there is scarce evidence in literature to exactly identify the most adequate onset timing for RRT.

    Successful implant placement at the time of extraction has been documented. Implant placement at the time of extraction was initially performed as a two-stage procedure often with barrier membranes and sophisticated second-stage surgical uncoverings. The authors describe the next generation of this technique, including atraumatic tooth removal with simultaneous root form, implant placement, and temporization at one appointment. This technique of "Immediate Total Tooth Replacement" allows for the maintenance of the bony housing and soft-tissue form that existed before extraction, while at the same time establishing a root form anchor in the bone for an esthetic restoration.

    The Boeing Company has been searching for replacements to cadmium plate. Two alloy plating systems seem close to meeting the needs of a cadmium replacement. The two alloys, zinc-nickel and tin-zinc are from alloy plating baths; both baths are neutral pH. The alloys meet the requirements for salt fog corrosion resistance, and both alloys excel as a paint base. Currently, tests are being performed on standard fasteners to compare zinc-nickel and tin-zinc on threaded hardware where cadmium is heavily used. The Hydrogen embrittlement propensity of the zinc-nickel bath has been tested, and just beginning for the tin-zinc bath. Another area of interest is the electrical properties on aluminum for tin-zinc and will be discussed. The zinc-nickel alloy plating bath is in production in Boeing Commercial Airplane Group for non-critical low strength steels. The outlook is promising that these two coatings will help The Boeing Company significantly reduce its dependence on cadmium plating.

  11. Sutureless aortic valve replacement

    PubMed Central

    Phan, Kevin

    2015-01-01

    The increasing incidence of aortic stenosis and greater co-morbidities and risk profiles of the contemporary patient population has driven the development of minimally invasive aortic valve surgery and percutaneous transcatheter aortic valve implantation (TAVI) techniques to reduce surgical trauma. Recent technological developments have led to an alternative minimally invasive option which avoids the placement and tying of sutures, known as “sutureless” or rapid deployment aortic valves. Potential advantages for sutureless aortic prostheses include reducing cross-clamp and cardiopulmonary bypass (CPB) duration, facilitating minimally invasive surgery and complex cardiac interventions, whilst maintaining satisfactory hemodynamic outcomes and low paravalvular leak rates. However, given its recent developments, the majority of evidence regarding sutureless aortic valve replacement (SU-AVR) is limited to observational studies and there is a paucity of adequately-powered randomized studies. Recently, the International Valvular Surgery Study Group (IVSSG) has formulated to conduct the Sutureless Projects, set to be the largest international collaborative group to investigate this technology. This keynote lecture will overview the use, the potential advantages, the caveats, and current evidence of sutureless and rapid deployment aortic valve replacement (AVR). PMID:25870807

    2014-02-01

    Total disc replacement (TDR) (partial disc replacement will not be described) has been used in the lumbar spine since the 1980s, and more recently in the cervical spine. Although the biomechanical concepts are the same and both are inserted through an anterior approach, lumbar TDR is conventionally indicated for chronic low back pain, whereas cervical TDR is used for soft discal hernia resulting in cervicobrachial neuralgia. The insertion technique must be rigorous, with precise centering in the disc space, taking account of vascular anatomy, which is more complex in the lumbar region, particularly proximally to L5-S1. All of the numerous studies, including prospective randomized comparative trials, have demonstrated non-inferiority to fusion, or even short-term superiority regarding speed of improvement. The main implant-related complication is bridging heterotopic ossification with resulting loss of range of motion and increased rates of adjacent segment degeneration, although with an incidence lower than after arthrodesis. A sufficiently long follow-up, which has not yet been reached, will be necessary to establish definitively an advantage for TDR, particularly in the cervical spine. PMID:24412045

    In November 1992, as a result of the International Montreal Protocol Treaty and its addenda, it was announced that worldwide production of halons would halt by January 1994. Research has shown that halons, with the component bromine, would likely be more damaging to the ozone layer than chlorofluorocarbons. Today, while other researchers are looking at ways to limit the use of or to recycle halogenated fire suppressants, the Naval Research Laboratory (NRL) is conducting active programs aimed at developing replacement agents. The program includes laboratory-scale screening of candidate agents, intermediate-scale chamber tests, and full-scale shipboard discharge fire tests. A substantial research effort is underway on the measurement of the effectiveness of alternate, nonhalogen-containing suppressants; the elucidation of the chemical and physical mechanisms by which they suppress fires; and the development of theory and models on the relationship of chemical structures to suppressive behavior.

    An epoxy grout suitable for use in mounting and positioning bearing runner plates used in hydrostatic bearing assemblies for rotatably mounting large radio telescope structures to stationary support pedestals is described. The epoxy grout may be used in original mountings or may be used as part of a replacement system for repairing cavities in existing grout resulting from grout deterioration. The epoxy grout has a relatively short work life and cure time even in the presence of hydraulic oil. The epoxy grout cures without shrinking or sagging to form a grout which is sufficiently strong and durable to provide a grout especially well suited for use under the high pressure loading and close tolerance requirements of large hydrostatic bearing assemblies.

    In 1959, William Russell and Rex Burch published "The Principles of Humane Experimental Technique". They proposed that if animals were to be used in experiments, every effort should be made to Replace them with non-sentient alternatives, to Reduce to a minimum the number of animals used, and to Refine experiments which used animals so that they caused the minimum pain and distress. These guiding principles, the "3 Rs" of animal research, were initially given little attention. Gradually, however, they have become established as essential considerations when animals are used in research. They have influenced new legislation aimed at controlling the use of experimental animals, and in the United Kingdom they have become formally incorporated into the Animal (Scientific) Procedures Act. The three principles, of Replacement, Reduction and Refinement, have also proven to be an area of common ground for research workers who use animals, and those who oppose their use. Scientists, who accept the need to use animals in some experiments, would also agree that it would be preferable not to use animals. If animals were to be used, as few as possible should be used and they should experience a minimum of pain or distress. Many of those who oppose animal experimentation, would also agree that until animal experimentation is stopped, Russell and Burch's 3Rs provide a means to improve animal welfare. It has also been recognised that adoption of the 3Rs can improve the quality of science. Appropriately designed experiments that minimise variation, provide standardised optimum conditions of animals care and minimise unnecessary stress or pain, often yield better more reliable data. Despite the progress made as a result of attention to these principles, several major problems have been identified. When replacing animals with alternative methods, it has often proven difficult to formally validate the alternative. This has proven a particular problem in regulatory toxicology

    Septins are guanine nucleotide-binding proteins that form hetero-oligomeric complexes, which assemble into filaments and higher-order structures at sites of cell division and morphogenesis in eukaryotes. Dynamic changes in the organization of septin-containing structures occur concomitantly with progression through the mitotic cell cycle and during cell differentiation. Septins also undergo stage-specific post-translational modifications, which have been implicated in regulating their dynamics, in some cases via purported effects on septin turnover. In our recent study, the fate of two of the five septins expressed in mitotic cells of budding yeast (Saccharomyces cerevisiae) was tracked using two complementary fluorescence-based methods for pulse-chase analysis. During mitotic growth, previously-made molecules of both septins (Cdc10 and Cdc12) persisted through multiple successive divisions and were incorporated equivalently with newly synthesized molecules into hetero-oligomers and higher-order structures. Similarly, in cells undergoing meiosis and the developmental program of sporulation, pre-existing copies of Cdc10 were incorporated into new structures. In marked contrast, Cdc12 was irreversibly excluded from septin complexes and replaced by another septin, Spr3. Here, we discuss the broader implications of these results and related findings with regard to how septin dynamics is coordinated with the mitotic cell cycle and in the yeast life cycle, and how these observations may relate to control of the dynamics of other complex multi-subunit assemblies.

    The Antenna Controller Replacement (ACR) software accurately points and monitors the Deep Space Network (DSN) 70-m and 34-m high-efficiency (HEF) ground-based antennas that are used to track primarily spacecraft and, periodically, celestial targets. To track a spacecraft, or other targets, the antenna must be accurately pointed at the spacecraft, which can be very far away with very weak signals. ACR s conical scanning capability collects the signal in a circular pattern around the target, calculates the location of the strongest signal, and adjusts the antenna pointing to point directly at the spacecraft. A real-time, closed-loop servo control algorithm performed every 0.02 second allows accurate positioning of the antenna in order to track these distant spacecraft. Additionally, this advanced servo control algorithm provides better antenna pointing performance in windy conditions. The ACR software provides high-level commands that provide a very easy user interface for the DSN operator. The operator only needs to enter two commands to start the antenna and subreflector, and Master Equatorial tracking. The most accurate antenna pointing is accomplished by aligning the antenna to the Master Equatorial, which because of its small size and sheltered location, has the most stable pointing. The antenna has hundreds of digital and analog monitor points. The ACR software provides compact displays to summarize the status of the antenna, subreflector, and the Master Equatorial. The ACR software has two major functions. First, it performs all of the steps required to accurately point the antenna (and subreflector and Master Equatorial) at the spacecraft (or celestial target). This involves controlling the antenna/ subreflector/Master-Equatorial hardware, initiating and monitoring the correct sequence of operations, calculating the position of the spacecraft relative to the antenna, executing the real-time servo control algorithm to maintain the correct position, and

    Low back pain consumes a large part of the community's resources dedicated to health care and sick leave. Back disorders also negatively affect the individual leading to pain suffering, decreased quality-of-life and disability. Chronic low back pain (CLBP) due to degenerative disc disease (DDD) is today often treated with fusion when conservative treatment has failed and symptoms are severe. This treatment is as successful as arthroplasty is for hip arthritis in restoring the patient's quality of life and reducing disability. Even so, there are some problems with this treatment, one of these being recurrent CLBP from an adjacent segment (ASD) after primarily successful surgery. This has led to the development of alternative surgical treatments and devices that maintain or restore mobility, in order to reduce the risk for ASD. Of these new devices, the most frequently used are the disc prostheses used in Total Disc Replacement (TDR). This thesis is based on four studies comparing total disc replacement with posterior fusion. The studies are all based on a material of 152 patients with DDD in one or two segments, aged 20-55 years that were randomly treated with either posterior fusion or TDR. The first study concerned clinical outcome and complications. Follow-up was 100% at both one and two years. It revealed that both treatment groups had a clear benefit from treatment and that patients with TDR were better in almost all outcome scores at one-year follow-up. Fusion patients continued to improve during the second year. At two-year follow-up there was a remaining difference in favour of TDR for back pain. 73% in the TDR group and 63% in the fusion group were much better or totally pain-free (n.s.), while twice as many patients in the TDR group were totally pain free (30%) compared to the fusion group (15%). Time of surgery and total time in hospital were shorter in the TDR group. There was no difference in complications and reoperations, except that seventeen of the

    The Western Area Power Administration (Western) is proposing to rebuild, operate, and maintain a 115-kilovolt (kV) transmission line between the Big George and Carter Mountain Substations in northwest Wyoming (Park and Hot Springs Counties). This environmental assessment (EA) was prepared in compliance with the National Environmental Policy Act (NEPA) and the regulations of the Council on Environmental Quality (CEQ) and the Department of Energy (DOE). The existing Big George to Carter Mountain 69-kV transmission line was constructed in 1941 by the US Department of Interior, Bureau of Reclamation, with 1/0 copper conductor on wood-pole H-frame structures without an overhead ground wire. The line should be replaced because of the deteriorated condition of the wood-pole H-frame structures. Because the line lacks an overhead ground wire, it is subject to numerous outages caused by lightning. The line will be 54 years old in 1995, which is the target date for line replacement. The normal service life of a wood-pole line is 45 years. Under the No Action Alternative, no new transmission lines would be built in the project area. The existing 69-kV transmission line would continue to operate with routine maintenance, with no provisions made for replacement.

    Katti, Kalpana S

    2004-12-10

    The current state of materials systems used in total hip replacement is presented in this paper. An overview of the various material systems used in total hip replacement reported in literature is presented in this paper. Metals, polymers, ceramics and composites are used in the design of the different components of hip replacement implants. The merits and demerits of these material systems are evaluated in the context of mechanical properties most suitable for total joint replacement such as a hip implant. Current research on advanced polymeric nanocomposites and biomimetic composites as novel materials systems for bone replacement is also discussed. This paper examines the current research in the materials science and the critical issues and challenges in these materials systems that require further research before application in biomedical industry.

    This Annual Status Report describes the design, development and implementation of the Minority On-Line Information Service (MOLIS) project by Federal Information Exchange, Inc. for the period of April 1, 1991 to March 31, 1992. Summary information detailing developments prior to this reporting period will also be included to establish a comprehensive perspective of the project. The goal of the MOLIS project, was to develop, design, pilot test on-line access to current information on minority colleges and universities and federal minority opportunities. Federal Information Exchange, Inc. (FIE), a diversified information services company recognized by researchers and educators as a leader in the field of information delivery services, was awarded a 5 year small business research grant to develop and implement MOLIS. Since April 29, 1991, the inauguration of its on-line service, MOLIS has provided current information on 138 Black and Hispanic colleges and universities -- including faculty and student profiles, financial data, research centers and equipment information, pre-college and education programs, emerging capabilities, enrollment data, administrative personnel data, and current events -- as well as minority opportunities from 8 participating federal agencies.

  2. ECTFE lined steel pipe is trouble-free with oleum

    1986-10-01

    Penreco, a division of Pennzoil Company in Karns City, PA, makes a variety of specialty petroleum products including white mineral oils and petroleum jellies for cosmetics and pharmaceuticals, and solvents for printing inks. A 2'' carbon steel transfer line failed repeatedly due to corrosion. A fluoropolymer--lined steel piping system was installed in 1983. The straight spool pieces were lined with a fluoropolymer that exhibits excellent resistance to a wide range of aggressive chemicals at temperatures to 450/sup 0/F. The elbows and tees were lined with ECTFE, a copolymer of ethylene (E) and chlorotrifluoroethylene (CTFE). The thermoplastic offers the same resistance to attack by chemicals and solvents as TFE, but is more resistant to abrasion, flexing and permeation by gases and liquids. About a year after the lined piping system was installed, the flanges began to leak. The problem was identified as embrittlement of the fluoropolymer used to line the spool pieces, which resulted in cracks and fissures in the integral flared flange gasket. Embrittlement and stress cracking may have been caused by free SO/sub 2/ reacting with the polymer. The flange faces of ECTFE were intact, and the lining showed no signs of corrosion or erosion by the aggressive media. In July 1984, the leaking pipe sections were replaced with new spool pieces lined with ECTFE, since the fittings lined with this material were still in excellent condition. The fittings were not replaced. The spent acid piping system, with both fittings and straight sections lines with ECTFE, has been trouble-free since July 1984. The superior permeation resistance of the fluoropolymer also enhances the integrity and service life of the steel pipe by eliminating the need for weepholes to prevent a build-up of gases and liquids, between the liner OD and pipe ID.

  11. Selecting the column configuration with lowest media replacement cost for small adsorption systems.

    PubMed

    Bausk, Artem S; Dvorak, Bruce I

    2016-04-15

    A framework was developed for preliminary evaluation of the relative media replacement costs of three alternative column configurations used for adsorption systems with two vessels, such as those serving small systems. The media replacement cost is the cost of fresh media and the replacement service cost (including transportation, labor, and other non-material costs). Cost normalization methods were developed in part based on the data from US EPA Arsenic Treatment Technology Demonstration Program. Adsorption equilibrium and kinetics were modeled using the PSDM model and breakthrough curves were normalized using the target effluent to influent concentration ratio (C/Co) and the mass transfer zone fraction (%MTZBT). Two factors were found to be important for the relative replacement cost of each configuration - the frequency which at least one column needed replacement of media, and the cycle replacement cost (CRCost) which is a combination of the fresh media cost and the replacement service cost. The lead-lag configuration has the lowest annual replacement cost at low target C/Co, high %MTZBT, and high CRCost ratios. The parallel configuration performs better at high target C/Co, high %MTZBT, and high CRCost ratios. Although the single configuration (two columns operated in tandem and replaced simultaneously) has higher media consumption compared to lead-lag and parallel, it can result in the lowest replacement cost at short %MTZBT and very low CRCost ratios due to savings in the replacement service cost.

  13. Prioritization methodology for chemical replacement

    Cruit, Wendy; Goldberg, Ben; Schutzenhofer, Scott

    1995-01-01

    Since United States of America federal legislation has required ozone depleting chemicals (class 1 & 2) to be banned from production, The National Aeronautics and Space Administration (NASA) and industry have been required to find other chemicals and methods to replace these target chemicals. This project was initiated as a development of a prioritization methodology suitable for assessing and ranking existing processes for replacement 'urgency.' The methodology was produced in the form of a workbook (NASA Technical Paper 3421). The final workbook contains two tools, one for evaluation and one for prioritization. The two tools are interconnected in that they were developed from one central theme - chemical replacement due to imposed laws and regulations. This workbook provides matrices, detailed explanations of how to use them, and a detailed methodology for prioritization of replacement technology. The main objective is to provide a GUIDELINE to help direct the research for replacement technology. The approach for prioritization called for a system which would result in a numerical rating for the chemicals and processes being assessed. A Quality Function Deployment (QFD) technique was used in order to determine numerical values which would correspond to the concerns raised and their respective importance to the process. This workbook defines the approach and the application of the QFD matrix. This technique: (1) provides a standard database for technology that can be easily reviewed, and (2) provides a standard format for information when requesting resources for further research for chemical replacement technology. Originally, this workbook was to be used for Class 1 and Class 2 chemicals, but it was specifically designed to be flexible enough to be used for any chemical used in a process (if the chemical and/or process needs to be replaced). The methodology consists of comparison matrices (and the smaller comparison components) which allow replacement technology

  14. Homologous gene replacement in Physarum

    SciTech Connect

    Burland, T.G.; Pallotta, D.

    1995-01-01

    The protist Physarum polycephalum is useful for analysis of several aspects of cellular and developmental biology. To expand the opportunities for experimental analysis of this organism, we have developed a method for gene replacement. We transformed Physarum amoebae with plasmid DNA carrying a mutant allele, ardD{Delta}1, of the ardD actin gene; ardD{Delta}1 mutates the critical carboxy-terminal region of the gene product. Because ardD is not expressed in the amoeba, replacement of ardD{sup +} with ardD{Delta}1 should not be lethal for this cell type. Transformants were obtained only when linear plasmid DNA was used. Most transformants carried one copy of ardD{Delta}1 in addition to ardD{sup +}, but in two (5%), ardD{sup +} was replaced by a single copy of ardD{Delta}1. This is the first example of homologous gene replacement in Physarum. ardD{Delta}1 was stably maintained in the genome through growth, development and meiosis. We found no effect of ardD{Delta}l on viability, growth, or development of any of the various cell types of Physarum. Thus, the carboxy-terminal region of the ardD product appears not to perform a unique essential role in growth or development. Nevertheless, this method for homologous gene replacement can be applied to analyze the function of any cloned gene. 38 refs., 6 figs., 1 tab.

  11. Cobra Probes Containing Replaceable Thermocouples

    NASA Technical Reports Server (NTRS)

    Jones, John; Redding, Adam

    2007-01-01

    A modification of the basic design of cobra probes provides for relatively easy replacement of broken thermocouples. Cobra probes are standard tube-type pressure probes that may also contain thermocouples and that are routinely used in wind tunnels and aeronautical hardware. They are so named because in side views, they resemble a cobra poised to attack. Heretofore, there has been no easy way to replace a broken thermocouple in a cobra probe: instead, it has been necessary to break the probe apart and then rebuild it, typically at a cost between $2,000 and $4,000 (2004 prices). The modified design makes it possible to replace the thermocouple, in minimal time and at relatively low cost, by inserting new thermocouple wire in a tube.

  13. Molecular replacement: tricks and treats

    SciTech Connect

    Abergel, Chantal

    2013-11-01

    To be successful, molecular replacement relies on the quality of the model and of the crystallographic data. Some tricks that could be applied to the models or to the crystal to increase the success rate of MR are discussed here. Molecular replacement is the method of choice for X-ray crystallographic structure determination provided that suitable structural homologues are available in the PDB. Presently, there are ∼80 000 structures in the PDB (8074 were deposited in the year 2012 alone), of which ∼70% have been solved by molecular replacement. For successful molecular replacement the model must cover at least 50% of the total structure and the C{sub α} r.m.s.d. between the core model and the structure to be solved must be less than 2 Å. Here, an approach originally implemented in the CaspR server (http://www.igs.cnrs-mrs.fr/Caspr2/index.cgi) based on homology modelling to search for a molecular-replacement solution is discussed. How the use of as much information as possible from different sources can improve the model(s) is briefly described. The combination of structural information with distantly related sequences is crucial to optimize the multiple alignment that will define the boundaries of the core domains. PDB clusters (sequences with ≥30% identical residues) can also provide information on the eventual changes in conformation and will help to explore the relative orientations assumed by protein subdomains. Normal-mode analysis can also help in generating series of conformational models in the search for a molecular-replacement solution. Of course, finding a correct solution is only the first step and the accuracy of the identified solution is as important as the data quality to proceed through refinement. Here, some possible reasons for failure are discussed and solutions are proposed using a set of successful examples.

  6. [MINIMALLY INVASIVE AORTIC VALVE REPLACEMENT].

    PubMed

    Tabata, Minoru

    2016-03-01

    Minimally invasive aortic valve replacement (MIAVR) is defined as aortic valve replacement avoiding full sternotomy. Common approaches include a partial sternotomy right thoracotomy, and a parasternal approach. MIAVR has been shown to have advantages over conventional AVR such as shorter length of stay and smaller amount of blood transfusion and better cosmesis. However, it is also known to have disadvantages such as longer cardiopulmonary bypass and aortic cross-clamp times and potential complications related to peripheral cannulation. Appropriate patient selection is very important. Since the procedure is more complex than conventional AVR, more intensive teamwork in the operating room is essential. Additionally, a team approach during postoperative management is critical to maximize the benefits of MIAVR. PMID:27295772

  7. Indications for ulnar head replacement.

    Berger, Richard A

    2008-08-01

    Implanting an endoprosthesis is a clinically proven means of reestablishing mechanical contact between the distal radius and ulna, thus providing the foundation for stability of the entire forearm. The indications for, contraindications to, and outcomes of ulnar head replacement are discussed, together with the underlying mechanics, pathomechanics of ulnar head excision, the theoretical basis for implant arthroplasty, and the designs that have been employed.

  8. Synthetic meniscus replacement: a review.

    PubMed

    2013-02-01

    The number of meniscus-related operations continues to rise due to the ageing and more active population. Irreparable meniscal lesions generally require (partial) meniscectomy. Although a majority of the patients benefit from pain relief and functional improvement post-meniscectomy, some remain symptomatic. As an alternative to a meniscal allograft, which is only indicated for the severely damaged meniscus, most patients can nowadays be treated by implantation of a synthetic meniscal substitute. Currently three of these implants, two partial and one total replacement, are clinically available and several others are in the stage of preclinical testing. Grossly, two types of meniscal substitutes can be distinguished: porous, resorbable implants that stimulate tissue regeneration and solid, non-resorbable implants that permanently replace the whole meniscus. Although the implantation of a porous meniscus replacement generally seems promising and improves clinical outcome measures to some degree, their superiority to partial meniscectomy still needs to be proven. The evaluation of new prostheses being developed requires a wider focus than has been adopted so far. Upon selection of the appropriate materials, preclinical evaluation of such implants should comprise a combination of (in vitro) biomechanical and (in vivo) biological tests, while up to now the focus has mainly been on biological aspects. Obviously, well-defined randomised controlled trials are necessary to support clinical performance of new implants. Since the use of a meniscus replacement requires an additional costly implant and surgery compared to meniscectomy only, the clinical outcome of new products should be proven to surpass the results of the conventional therapies available.

    2015-01-01

    Degenerative, ischemic, rheumatic and infectious (endocarditis) processes are responsible for mitral valve disease in adults. Mitral valve repair has been widely regarded as the optimal surgical procedure to treat mitral valve dysfunction of all etiologies. The supporting evidence for repair over replacement is strongest in degenerative mitral regurgitation. The aim of the present review is to summarize the data in each category of mitral insufficiency and to provide recommendations based upon this data. PMID:26309824

    2016-01-01

    Today tobacco use is the single greatest preventable cause of death in the world. Tobacco use is often incorrectly perceived to be solely a personal choice. This is contradicted by the fact that when fully aware of the health impact, most tobacco users want to quit but find it difficult to stop due to the addictiveness of nicotine. Henceforth, Nicotine replacement therapy (NRT) came into existence which temporarily replaces much of the nicotine from tobacco to reduce motivation to consume tobacco and nicotine withdrawal symptoms, thus easing the transition from cigarette smoking to complete abstinence. Various alternative nicotine sources (gum, transdermal patch, nasal spray, inhaler and sublingual tablets/lozenges) have been incorporated into tobacco cessation programs. Recent research is more focusing on rapid delivery of nicotine (Nicotine preloading, true pulmonary inhaler) and immunological approaches (nicotine vaccine) to tackle nicotine dependence. These NRTs are in general well tolerated and have minimal adverse effects. The review aims to summarize literature on various modes of nicotine replacement therapy methods currently used to treat nicotine dependence, and to give an overview about future possible approaches to treat tobacco use disorder.

    Newell, J P; Kappagoda, C T; Stoker, J B; Deverall, P B; Watson, D A; Linden, R J

    1980-01-01

    A controlled trial was undertaken to examine the efficacy of physical training in patients recovering from the replacement of a single heart valve. Patients were allocated to a test or control group two weeks after operation. Each patient performed a submaximal exercise test at entry, and 12 and 24 weeks after this test. The Canadian Air Force exercise programme was undertaken by the test group, while the control group continued normal activities for the 24 weeks between the first and last exercise group. A regression line of submaximal heart rate on oxygen consumption was calculated from the data of each exercise test in each patient. Alterations in this line were used as an "index" of changes in "cardiorespiratory fitness". The individual results showed a consistent improvement in "cardiorespiratory fitness" over the first 12 weeks in both groups. Only patients in the test group continued to improve between 12 and 24 weeks. Thus the exercise programme modified the recovery of "cardiorespiratory fitness" after operation. Results in patients who developed clinical complications, and were excluded from the trial, predicted a deteriorating clinical condition. This finding suggested that sequential exercise tests are of value after cardiac surgery. PMID:7459147

The serum used in cell culture media can be replaced by a mixture of hormones and some accesory blood factors. The pituitary cell line GH3 can be grown in a medium in which serum is replaced by triiodothyronine, transferrin, parathormone, tyrotrophin releasing hormone and somatomedins. Hela and BHK cell strains can also be grown in serum free medium supplemented with hormones. Each cell type appears to have different hormonal requirements yet it may found that some hormones are required for most cell types. PMID:1026199

    In 2030, when baby boomers reach 65 years of age and represent 18% of the population, it is anticipated that 67 million adults will have a diagnosis of arthritis increasing the demand for total hip and knee arthroplasty. With the growing emphasis on patient- and family-centered care, the aim of this project was to assess the patient experience of patients and families throughout the entire spectrum of the total joint replacement service line care at a university regional trauma hospital. A shadowing methodology as defined by the Institute for Health Improvement was utilized. Eight patient/family groups undergoing total joint replacements were shadowed. The mapped care experience included time, caregiver, activity, shadower observations, and impressions. Findings revealed inconsistencies in the delivery of patient- and family-centered care. Communication and interactions were predominantly provider-centric, with a focus on care routines versus the patient and family, and anticipation that care would be medically directed. PMID:26375835

    Total Knee replacement (TKR) is one of the commonest arthroplasty surgeries performed. Various techniques of closures in TKR are described. This technical note describes an useful technique of achieving water tight closure in TKR. An optimal tension watertight closure also reduces the chances of dead space hematomas and infection. The author has described his technique where the soft tissues are never unduly compromised. In his experience the patient can be mobilized freely in bed and even allowed to sleep prone after first wound check.

    Hemophilia B is an X chromosome linked hereditary hemorrhagic disease, which is caused by the lose function mutation of factor IX (FIX), and significantly affects the patients' lifespan and life quality. The severity of hemophilia B depends on the FIX level in the plasma. By referring to the relevant literatures, we reviewed and summarized hemophilia B replacement therapies. Specifically, we focus on recombinant factor IX products on the market and those in the pipeline, especially on the long-acting factor IX drugs, to provide the basis for researches of new hemophilia B drugs.

  20. Replacing London's cast iron mains

    Thorne, A. ); Mathews, P. )

    1992-07-01

    This paper discusses the cast iron gas distribution systems that exist in many cities and contains considerable amounts of pipe that vary in age from 20 to 150 years. In many ways, cast iron is an excellent material. It is inherently corrosion resistant, easy to install and cheap. However, it is also brittle and smaller diameter cast iron pipe has a relatively low beam strength. This can lead, under some circumstances, to failure without external warning, with typically a full-circumferential failure. In congested areas this can lead to serious consequences. As a result, cast iron replacement programs are a common feature in such urban gas distribution systems.

  1. Midflexion instability in primary total knee replacement: a review

    PubMed Central

    Ramappa, Manjunath

    2015-01-01

    Introduction: Midflexion instability in primary total knee replacement (TKR) is an evolving concept. Successful treatment of instability requires an understanding of the different types of instability. Methods: A literature review was performed to identify information pertinent to midflexion instability in primary total knee replacement, utilising PRISMA guidelines. Databases searched included Embase, Medline, All of the Cochrane Library, PubMed and cross references. Results: Three factors, i.e., elevated joint line, multiradii femoral component and medial collateral ligament (MCL) laxity, were identified to influence midflexion instability. Literature suggested mediolateral instability at 30–60° of flexion as diagnostic of midflexion instability. Literature search also revealed paucity in clinical studies analysing midflexion instability. Most of the evidence was obtained from cadaveric studies for elevated joint line and MCL laxity. Clinical studies on multiradii femoral component were limited by their small study size and early followup period. Conclusion: Elevated joint line, multiradii femoral component and MCL laxity have been suggested to cause midflexion laxity in primary TKR. Due to limitations in available evidence, this review was unable to raise the strength of overall evidence. Future well-designed clinical studies are essential to make definitive conclusions. This review serves as a baseline for future researchers and creates awareness for routine assessment of midflexion instability in primary total knee replacement. PMID:27163080

  2. The future of nicotine replacement.

    PubMed

    Russell, M A

    1991-05-01

    Following in the wake of progress forged by nicotine chewing gum, a new generation of nicotine replacement products will soon be available as aids to giving up smoking. These range from nicotine skin patches, which take 6-8 hrs to give very flat steady-state peak blood levels, to nicotine vapour inhalers which mimic the transient high-nicotine boli that follow within a few seconds of each inhaled puff of cigarette smoke. Other products undergoing clinical trials include a nasal nicotine spray and nicotine lozenges. It is argued here that it is not so much the efficacy of new nicotine delivery systems as temporary aids to cessation, but their potential as long-term alternatives to tobacco that makes the virtual elimination of tobacco a realistic future target. Their relative safety compared with tobacco is discussed. A case is advanced for selected nicotine replacement products to be made as palatable and acceptable as possible and actively promoted on the open market to enable them to compete with tobacco products. They will also need health authority endorsement, tax advantages and support from the anti-smoking movement if tobacco use is to be gradually phased out altogether. PMID:1859935

    A case report of a professional contemporary dancer who successfully returned to the stage after bilateral total hip replacements (THR) for osteoarthritis is presented, together with her own commentary and a retrospective cohort study of total hip replacements in dancers. In the presented cohort, there were no post-operative dislocations or infections, the original pain had been relieved, rehabilitation was objectively normal and all resumed their dance (teaching) activities. Nevertheless, they were disappointed about the prolonged rehabilitation. Due to their high demands as professional dancers, post-operative expectations were too optimistic in view of the usual quick and favourable results of THR in the older and less physically active, general population. In all dancers with unilateral osteoarthritis, the left hip was involved, which may reflect the tendency to use the left leg as standing leg and be suggestive that strenuous physical activity may lead to osteoarthritis. Better rehabilitation guidelines are needed for dancer patients undergoing THR, especially drawing their attention to realistic post-operative expectations. PMID:23588878

    This paper reports on damaged sections of Botas' dual 30-in. gas line carrying USSR gas across the Marmara Sea to Turkey that were replaced 30 days ahead of contract schedule. Tefken Construction and Installation Co., Inc., Istanbul, working under a $4-million contract, replaced two sections on one of the dual lines near Ambarli, Turkey, within a two-month period. The offshore system stretches 33-mi under the Marmara Sea with some pipe laid at 262-ft maximum water depths. The scope of the project was to replace a 426-ft offshore approach to the northern shoreline and a 984-ft onshore section, which were damaged by a submarine landslide.

  11. Service employees give as they get: internal service as a moderator of the service climate-service outcomes link.

    PubMed

    2011-03-01

    We lend theoretical insight to the service climate literature by exploring the joint effects of branch service climate and the internal service provided to the branch (the service received from corporate units to support external service delivery) on customer-rated service quality. We hypothesized that service climate is related to service quality most strongly when the internal service quality received is high, providing front-line employees with the capability to deliver what the service climate motivates them to do. We studied 619 employees and 1,973 customers in 36 retail branches of a bank. We aggregated employee perceptions of the internal service quality received from corporate units and the local service climate and external customer perceptions of service quality to the branch level of analysis. Findings were consistent with the hypothesis that high-quality internal service is necessary for branch service climate to yield superior external customer service quality. PMID:21142340

  12. Identification and definition of unbundled electric generation and transmission services

    1995-03-01

    State and federal regulators, private and public utilities, large and small customers, power brokers and marketers, and others are engaged in major debates about the future structure of the electric industry. Although the outcomes are far from certain, it seems clear that customers will have much greater choices about the electric services they purchase and from whom they buy these services. This report examines the ``ancillary`` services that are today buried within the typical vertically integrated utility. These ancillary services support and make possible the provision of the basic services of generating capacity, energy supply, and power delivery. These ancillary services include: Management of generating units; reserve generating capacity to follow variations in customer loads, to provide capacity and energy when generating units or transmission lines suddenly fall, to maintain electric-system stability, and to provide local-area security; transmission-system monitoring and control; replacement of real power and energy losses; reactive-power management and voltage regulation; transmission reserves; repair and maintenance of the transmission network; metering, billing, and communications; and assurance of appropriate levels of power quality. Our focus in this report, the first output from a larger Oak Ridge National Laboratory project, is on identification and definition of these services. Later work in this project will examine more closely the costs and pricing options for each service.

  13. Mitochondrial Replacement: Ethics and Identity.

    2015-11-01

    Mitochondrial replacement techniques (MRTs) have the potential to allow prospective parents who are at risk of passing on debilitating or even life-threatening mitochondrial disorders to have healthy children to whom they are genetically related. Ethical concerns have however been raised about these techniques. This article focuses on one aspect of the ethical debate, the question of whether there is any moral difference between the two types of MRT proposed: Pronuclear Transfer (PNT) and Maternal Spindle Transfer (MST). It examines how questions of identity impact on the ethical evaluation of each technique and argues that there is an important difference between the two. PNT, it is argued, is a form of therapy based on embryo modification while MST is, instead, an instance of selective reproduction. The article's main ethical conclusion is that, in some circumstances, there is a stronger obligation to use PNT than MST. PMID:26481204

  14. Optimal randomized scheduling by replacement

    SciTech Connect

    Saias, I.

    1996-05-01

    In the replacement scheduling problem, a system is composed of n processors drawn from a pool of p. The processors can become faulty while in operation and faulty processors never recover. A report is issued whenever a fault occurs. This report states only the existence of a fault but does not indicate its location. Based on this report, the scheduler can reconfigure the system and choose another set of n processors. The system operates satisfactorily as long as, upon report of a fault, the scheduler chooses n non-faulty processors. We provide a randomized protocol maximizing the expected number of faults the system can sustain before the occurrence of a crash. The optimality of the protocol is established by considering a closely related dual optimization problem. The game-theoretic technical difficulties that we solve in this paper are very general and encountered whenever proving the optimality of a randomized algorithm in parallel and distributed computation.

    The stabilised gliding knee prosthesis is a compromise between hinged joints and condylar prostheses. It is a two-piece implant designed to allow normal gliding movements of flexion and extension and which, stabilised by a connecting rod between the femoral and tibial components, allows a designed laxity of rotation and lateral movements. A modification of the original femoral component is described. Two hundred and forty-five knee replacement operations have been done between January 1973 and September 1977 and the results are reported. The results using this prosthesis are at least equal to those using hinged or condylar prostheses. So far there has been no case of spontaneous loosening of the components and the implant can be used in patients who, because of severe deformities and instability, are unsuitable for condylar prostheses.

    The soeWINDOW program automates the generation of an ITAR (International Traffic in Arms Regulations)-compliant sub-RSOE (Replacement Sequence of Events) by extracting a specified temporal window from an RSOE while maintaining page header information. RSOEs contain a significant amount of information that is not ITAR-compliant, yet that foreign partners need to see for command details to their instrument, as well as the surrounding commands that provide context for validation. soeWINDOW can serve as an example of how command support products can be made ITAR-compliant for future missions. This software is a Perl script intended for use in the mission operations UNIX environment. It is designed for use to support the MRO (Mars Reconnaissance Orbiter) instrument team. The tool also provides automated DOM (Distributed Object Manager) storage into the special ITAR-okay DOM collection, and can be used for creating focused RSOEs for product review by any of the MRO teams.

    2015-01-01

    Dental morphology and patterns of tooth replacement in representatives of the clade Pliosauridae (Reptilia, Sauropterygia) are evaluated in detail. The jaws of one basal (Thalassiodracon hawkinsii) and two derived species (Pliosaurus carpenteri, Pliosaurus kevani) were visualized by μCT scans, and the ontogenetic patterns, or ‘movement paths’, of replacement teeth could be mapped. Other specimens (Peloneustes philarchus and Pliosaurus westbuyensis) with well-preserved jaws containing functional and replacement teeth in situ were also examined directly, and waves of tooth replacement could be inferred from the degree of in situ tooth development and the fusion between functional and replacement alveoli. The analysis revealed symmetrical tooth eruption over the medial axis throughout the length of the jaw in the basal pliosaurid Thalassiodracon. By contrast, symmetrical tooth eruption patterns occur only along the anterior sections of the jaws of derived pliosaurids. In Pliosaurus, replacement schedules differ in the anterior and posterior portions of the jaws and appear to correlate with differences in tooth morphology and symmetrical replacement. The anterior teeth exhibit longer replacement cycle periods and symmetrical replacement, while shorter cycle periods and asymmetry are seen posteriorly. A longer period suggests slower replacement and is characteristic of large, specialized caniniform teeth in the longer snouted Late Jurassic taxa. Smaller posterior teeth have a shorter period and therefore a faster replacement cycle. The transition from long to short replacement period over the length of the jaw is thought to account for the loss of symmetry. This differentiation could relate to differential tooth function and a type of heterodonty. We therefore propose a new model of pliosaurid tooth replacement patterns and present it in a phylogenetic context. PMID:26715998

  7. Visual Image Sensor Organ Replacement

    Maluf, David A.

    2014-01-01

    This innovation is a system that augments human vision through a technique called "Sensing Super-position" using a Visual Instrument Sensory Organ Replacement (VISOR) device. The VISOR device translates visual and other sensors (i.e., thermal) into sounds to enable very difficult sensing tasks. Three-dimensional spatial brightness and multi-spectral maps of a sensed image are processed using real-time image processing techniques (e.g. histogram normalization) and transformed into a two-dimensional map of an audio signal as a function of frequency and time. Because the human hearing system is capable of learning to process and interpret extremely complicated and rapidly changing auditory patterns, the translation of images into sounds reduces the risk of accidentally filtering out important clues. The VISOR device was developed to augment the current state-of-the-art head-mounted (helmet) display systems. It provides the ability to sense beyond the human visible light range, to increase human sensing resolution, to use wider angle visual perception, and to improve the ability to sense distances. It also allows compensation for movement by the human or changes in the scene being viewed.

    Temporomandibular disorders (TMD) are part of a heterogeneous group of pathologies that manifest with a constellation of signs and symptoms. They are the most frequent cause of chronic orofacial pain and are prevalent in 12% of the general population. Despite the debilitating nature of these disorders, there is no standardization for treatment of the diseased temporomandibular joint (TMJ). In this review, we present an overview of the functional anatomy of the TMJ and the engineering concepts that must be understood to better understand the indications for surgical management, the types of available treatments and the requirements for reconstruction. A comparison is made of the clinical outcomes with autogenous versus alloplastic reconstruction, including a history of alloplastic materials and the design features of currently available implants. Emphasis is made on material selection, modulus, stiffness, notch sensitivity and modularity. For the treatment of TMD, engineered TMJ alloplastic replacements have had considerable promise with additional room for improvement using new materials and recent design concepts. PMID:22363183

    1989-01-01

    The current regulatory climate continues to prod today's nuclear utilities toward safer and more reliable operation of their plants. U.S. Nuclear Regulatory Commission guides NUREG-0660, NUREG-0696, and Supplement I to NUREG-0737 have all set forth increased requirements for plant monitoring. In response, the industry has looked at their existing plant computer systems as targets for enhancement or upgrade. This external pressure is nearly matched by the increasing demands made on existing computer systems by utility engineering and operations departments. The longer utilities postpone this evolution, the more likely they are to replace the entire system rather than upgrade the existing one. The older systems become harder to maintain and eventually are technically inferior to new systems, which have benefited from advances in computer technology in recent years. Enhancements become less economically advantageous than system replacements as the spread in technology widens. The object of this paper is to describe the Plant Process Computer Replacement Project at Philadelphia Electric Company's (PECo's) Peach Bottom Atomic Power Station. This paper explores (a) the impact on the plant, (b) the design and engineering services required, and (c) the planning and communication essential to a successful computer replacement project.

    The first part of this article discussed the challenge of replacing reserves while maintaining high levels of profitability. An examination of the 82 largest US-based, publicly traded exploration and production (E and P) companies, grouped by size, suggested a potential conflict between reserves replacement and profitability--a ``devil`s dilemma`` between long term viability and financial performance. The 10 largest companies failed to replace their production in the US or worldwide (although they did in non-US operations). They were, however, the most profitable on a per-barrel-equivalent basis. In general, the smaller the company, the higher its reserves-replacement ratio, reflecting greater relative effort but lower unit profitability. This article examines the difficulties that companies face in reserves replacement planning, the accommodations they make to these difficulties, and the problems caused by these accommodations. It then suggests an analytical structure for reserves replacement planning that contributes to overcoming the difficulties.

    2015-01-01

    Cervical disc replacement (CDR) has emerged as an alternative surgical option to cervical arthrodesis. With increasing numbers of patients and longer follow-ups, complications related to the device and/or aging spine are growing, leaving us with a new challenge in the management and surgical revision of CDR. The purpose of this study is to review the current literature regarding reoperations following CDR and to discuss about the approaches and solutions for the current and future potential complications associated with CDR. The published rates of reoperation (mean, 1.0%; range, 0%-3.1%), revision (mean, 0.2%; range, 0%-0.5%), and removal (mean, 1.2%; range, 0%-1.9%) following CDR are low and comparable to the published rates of reoperation (mean, 1.7%; range; 0%-3.4%), revision (mean, 1.5%; range, 0%-4.7%), and removal (mean, 2.0%; range, 0%-3.4%) following cervical arthrodesis. The surgical interventions following CDR range from the repositioning to explantation followed by fusion or the reimplantation to posterior foraminotomy or fusion. Strict patient selection, careful preoperative radiographic review and surgical planning, as well as surgical technique may reduce adverse events and the need for future intervention. Minimal literature and no guidelines exist for the approaches and techniques in revision and for the removal of implants following CDR. Adherence to strict indications and precise surgical technique may reduce the number of reoperations, revisions, and removals following CDR. Long-term follow-up studies are needed, assessing the implant survivorship and its effect on the revision and removal rates. PMID:26097667

    This paper describes a maintenance problem in a fusion power plant. The problem is to specify which life limited parts should be replaced when there is an opportunity. The objective is to minimize the cost rate of replacement parts and of maintenance actions while satisfying a power plant availability constraint. The maintenance policy is to look ahead and replace all parts that will reach their life limits within a time called a screen. Longer screens yield greater system availabilities because more parts are replaced prior to their life limits.

    Total quality management (TQM) is based on understanding customer needs, improving key processes that affect customer satisfaction, and creating cross-functional teams to resolve process problems. This article describes application of TQM principles and problem-solving processes to improve one OR's medication exchange system. The problem was excessive monthly pharmacy medication replacement costs. The goal was to reduce the monthly medication replacement costs by 50%. Within four months, monthly medication replacement charges decreased from $656 to $302, and by one year, monthly charges decreased to $160. The new process had fewer steps, fewer staff members involved, and fewer delays in medication replacement. PMID:8085806

    2007-01-01

    Dendroecological techniques were applied to reconstruct stand-replacing fire history in upper montane forests in northern New Mexico and southern Colorado. Fourteen stand-replacing fires were dated to 8 unique fire years (1842-1901) using four lines of evidence at each of 12 sites within the upper Rio Grande Basin. The four lines of evidence were (i) quaking aspen (Populus tremuloides Michx.) inner-ring dates, (ii) fire-killed conifer bark-ring dates, (iii) tree-ring width changes or other morphological indicators of injury, and (iv) fire scars. The annual precision of dating allowed the identification of synchronous stand-replacing fire years among the sites, and co-occurrence with regional surface fire events previously reconstructed from a network of fire scar collections in lower elevation pine forests across the southwestern United States. Nearly all of the synchronous stand-replacing and surface fire years coincided with severe droughts, because climate variability created regional conditions where stand-replacing fires and surface fires burned across ecosystems. Reconstructed stand-replacing fires that predate substantial Anglo-American settlement in this region provide direct evidence that stand-replacing fires were a feature of high-elevation forests before extensive and intensive land-use practices (e.g., logging, railroad, and mining) began in the late 19th century. ?? 2007 NRC.

  20. A cost analysis of kidney replacement therapy options in Palestine.

    2015-01-01

    This study provides a cost analysis of kidney replacement therapy options in Palestine. It informs evidence-based resource allocation decisions for government-funded kidney disease services where transplant donors are limited, and some of the common modalities, i.e., peritoneal dialysis (PD) and home hemodialysis (HD), are not widely available due to shortages of qualified staff, specialists, and centers to follow the patient cases, provide training, make home visits, or provide educational programs for patients. The average cost of kidney transplant was US$16,277 for the first year; the estimated cost of HD per patient averaged US$16,085 per year--nearly as much as a transplant. Consistent with prior literature and experience, while live, related kidney donors are scarce, we found that kidney transplant was more adequate and less expensive than HD. These results have direct resource allocation implications for government-funded kidney disease services under Palestinian Ministry of Health. Our findings strongly suggest that investing in sufficient qualified staff, equipment, and clinical infrastructure to replace HD services with transplantation whenever medically indicated and suitable kidney donors are available, as well as deploying PD programs and Home HD programs, will result in major overall cost savings. Our results provide a better understanding of the costs of kidney disease and will help to inform Ministry of Health and related policy makers as they develop short- and long-term strategies for the population, in terms of both cost savings and enhanced quality of life.

    Addressing the needs to achieve the highest standards at multidisciplinary team meetings at the Stroke Unit of Broomfield Hospital, an electronic version is applied instead of the traditional paper model. This is to ensure that patients within the unit are receiving appropriate care and their progress is monitored throughout their entire journey. This also enables the stroke team to retrieve old information anywhere in the hospital, electronically, from previous documentations to compare progress of rehabilitation. The electronic model also helps when assessing readmission or those who attend the stroke clinics to clarify new onset changes from residual weakness. The tool kit estimates Barthel Index score for activities of daily living and Rivermead Mobility Index for physical capacity assessment weekly as the team attending the meetings. The goals from all disciplines, physiotherapists, occupational therapists, speech and language therapists, and nurses are clearly documented along with patient cognition, emotion, and perception. This initiative commenced in late April 2013 and the first clinical outcome assessments performed at the beginning of September 2013, enabling the stroke team to assess rehabilitation activities and achievements. Front-line staff expressed satisfaction with the initiative model, which successfully managed to monitor and analyze the rehabilitation activities within the stroke unit. PMID:25440331

    Line configuration and balancing is to select the type of line and allot a given set of operations as well as machines to a sequence of workstations to realize high-efficiency production. Most of the current researches for machining line configuration and balancing problems are related to dedicated transfer lines with dedicated machine workstations. With growing trends towards great product variety and fluctuations in market demand, dedicated transfer lines are being replaced with flexible machining line composed of identical CNC machines. This paper deals with the line configuration and balancing problem for flexible machining lines. The objective is to assign operations to workstations and find the sequence of execution, specify the number of machines in each workstation while minimizing the line cycle time and total number of machines. This problem is subject to precedence, clustering, accessibility and capacity constraints among the features, operations, setups and workstations. The mathematical model and heuristic algorithm based on feature group strategy and polychromatic sets theory are presented to find an optimal solution. The feature group strategy and polychromatic sets theory are used to establish constraint model. A heuristic operations sequencing and assignment algorithm is given. An industrial case study is carried out, and multiple optimal solutions in different line configurations are obtained. The case studying results show that the solutions with shorter cycle time and higher line balancing rate demonstrate the feasibility and effectiveness of the proposed algorithm. This research proposes a heuristic line configuration and balancing algorithm based on feature group strategy and polychromatic sets theory which is able to provide better solutions while achieving an improvement in computing time.

  17. Replaceable blade turbine and stationary specimen corrosion testing facility

    NASA Technical Reports Server (NTRS)

    Santoro, G. J.; Calfo, F. D.

    1985-01-01

    A facility was constructed to provide relatively low cost testing of hot section turbine blade and vane materials under hot corrosion conditions more akin to service environments. The facility consists of a small combustor whose pressurized gas flow can be directed to either a test section consisting of three small cascaded specimens or to a partial admittance single-stage axial flow turbine. The turbine rotor contains 28 replaceable turbine blades. The combustion gases resulting from the burning of Jet A-l fuel can be seeded with measured amounts of alkali salts. This facility is described here along with preliminary corrosion test results obtained during the final checkout of the facility.

    2014-04-01

    The objective of this article is to provide a review of the fundamental aspects of body fluid balance and the physiological consequences of water imbalances, as well as discuss considerations for the optimal composition of a fluid replacement beverage across a broad range of applications. Early pioneering research involving fluid replacement in persons suffering from diarrheal disease and in military, occupational, and athlete populations incurring exercise- and/or heat-induced sweat losses has provided much of the insight regarding basic principles on beverage palatability, voluntary fluid intake, fluid absorption, and fluid retention. We review this work and also discuss more recent advances in the understanding of fluid replacement as it applies to various populations (military, athletes, occupational, men, women, children, and older adults) and situations (pathophysiological factors, spaceflight, bed rest, long plane flights, heat stress, altitude/cold exposure, and recreational exercise). We discuss how beverage carbohydrate and electrolytes impact fluid replacement. We also discuss nutrients and compounds that are often included in fluid-replacement beverages to augment physiological functions unrelated to hydration, such as the provision of energy. The optimal composition of a fluid-replacement beverage depends upon the source of the fluid loss, whether from sweat, urine, respiration, or diarrhea/vomiting. It is also apparent that the optimal fluid-replacement beverage is one that is customized according to specific physiological needs, environmental conditions, desired benefits, and individual characteristics and taste preferences.

    Replacement solvents for use in chemical synthesis include polymer-immobilized solvents having a flexible polymer backbone and a plurality of pendant groups attached onto the polymer backbone, the pendant groups comprising a flexible linking unit bound to the polymer backbone and to a terminal solvating moiety. The polymer-immobilized solvent may be dissolved in a benign medium. Replacement solvents for chemical reactions for which tetrahydrofuran or diethyl may be a solvent include substituted tetrahydrofurfuryl ethers and substituted tetrahydro-3-furan ethers. The replacement solvents may be readily recovered from the reaction train using conventional methods.

  7. Centrifugal chillers - CFC retrofit versus replacement. Final report

    SciTech Connect

    Kistler, P.

    1997-09-01

    As of January 1, 1996, chlorofluorocarbon (CFC) refrigerants CFC-11 and CFC-12 can no longer be produced in the United States. It is estimated that as many as 60,000 or 74% of CFC chillers in service today in industrial, commercial, and institutional buildings still use the `banned` refrigerants. In addition, most of the Navy`s centrifugal chillers also use these refrigerants. In May 1994, the Naval Facilities Engineering Command dictated (NAVFAC Notice 5090) that all shore-based Navy Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) equipment containing Class I Ozone Depleting Substance (ODS) be replaced or converted by December 41,2000. Equipment conversions must utilize an approved refrigerant - one with an Ozone Depleting Potential (ODP) of 0.05 or less. The decision to eliminate CFC refrigerants at Navy facilities must begin with a CFC management plan. The plan should address items such as, reducing leakage in existing CFC systems, HVAC maintenance personnel training standards, and retrofitting or replacing CFC refrigerant-using equipment. The decision to retrofit or replace CFC refrigerant chiller must involve the chiller manufacturer. Manufacturers will (often at no cost) evaluate your existing cooling system, determine the most appropriate retrofit method, and determine which option is the most economical choice.

Rejecting the option of partial replacement just because of parts unavailability is not acceptable when it seems the safest way to get the best result. Help can come from orthopedic surgeons themselves, if they give to their patient precise reports on the primary arthroplasty. The technical references of all the devices devoted to joint arthroplasty should not only be collected by public health services (AFSSAPS) but they should also be available to orthopedic surgeons. The real production cost of prosthetic elements should be taken into account in order to encourage the companies to deliver parts that are not on the market anymore. PMID:16327696

  9. Replacing fallow by cover crops: economic sustainability

    NASA Astrophysics Data System (ADS)

    Gabriel, José Luis; Garrido, Alberto; Quemada, Miguel

    2013-04-01

    Replacing fallow by cover crops in intensive fertilized systems has been demonstrated as an efficient tool for reducing nitrate leaching. However, despite the evident environmental services provided and the range of agronomic benefits documented in the literature, farmers' adoption of this new technology is still limited because they are either unwilling or unable, although adoption reluctance is frequently rooted in low economic profitability, low water se efficiency or poor knowledge. Economic analyses permit a comparison between the profit that farmers obtain from agricultural products and the cost of adopting specific agricultural techniques. The goal of this study was to evaluate the economic impact of replacing the usual winter fallow with cover crops (barley (Hordeum vulgare L., cv. Vanessa), vetch (Vicia villosa L., cv. Vereda) and rapeseed (Brassica napus L., cv. Licapo)) in irrigated maize systems and variable Mediterranean weather conditions using stochastic Monte-Carlo simulations of key farms' financial performance indicators. The three scenarios studied for each cover crop were: i) just leaving the cover crop residue in the ground, ii) leaving the cover crop residue but reduce following maize fertilization according to the N available from the previous cover crop and iii) selling the cover crop residue for animal feeding. All the scenarios were compared with respect to a typical maize-fallow rotation. With observed data from six different years and in various field trials, looking for different weather conditions, probability distribution functions of maize yield, cover crop biomass production and N fertilizer saving was fitted. Based in statistical sources maize grain price, different forage prices and the cost of fertilizer were fitted to probability distribution functions too. As result, introducing a cover crop involved extra costs with respect to fallow as the initial investment, because new seed, herbicide or extra field operations. Additional

  11. Mitochondrial DNA replacement versus nuclear DNA persistence

    NASA Astrophysics Data System (ADS)

    Serva, Maurizio

    2006-10-01

    In this paper we consider two populations whose generations are not overlapping and whose size is large. The number of males and females in both populations is constant. Any generation is replaced by a new one and any individual has two parents concerning nuclear DNA and a single one (the mother) concerning mtDNA. Moreover, at any generation some individuals migrate from the first population to the second. In a finite random time T, the mtDNA of the second population is completely replaced by the mtDNA of the first. In the same time, the nuclear DNA is not completely replaced and a fraction F of the ancient nuclear DNA persists. We compute both T and F. Since this study shows that complete replacement of mtDNA in a population is compatible with the persistence of a large fraction of nuclear DNA, it may have some relevance for the 'out of Africa'/multiregional debate in palaeoanthropology.

    Case 1:a 47-year-old woman who complained of sweating, finger tremor, and chest pain was diagnosed with coarctation of the aorta and hyperthyroidism. She had been diagnosed with hypertension at 25 years of age but had not undergone further examination. Graft replacement was performed without cardiopulmonary or temporary bypass. Case 2:a 30-year-old woman was diagnosed with coarctation during infertility treatment. Although health screening had revealed hypertension 8 years previously, no further assessment took place. She underwent graft replacement with partial cardiopulmonary bypass. In both cases, we conducted a clamp test to decide whether cardiopulmonary or partial bypass was necessary for graft replacement. Blood pressure discrepancy between upper and lower extremities disappeared immediately after surgery, and no ischemic complications were observed. Hypertension in young adults should prompt further scrutiny for anatomical disorders such as coarctation. A clamp test is considered helpful regarding the surgical approach to graft replacement for coarctation. PMID:26197824

    Background: Cervical disc replacement is becoming an increasingly popular treatment option for cervical myelopathy. It retains motion at the affected segment, unlike anterior cervical discectomy and fusion. The aim of this study is to assess the outcomes of a series of patients who underwent Activ C disc replacement for cervical myelopathy. Materials and Methods: A series of patients at the above Trust with clinical and radiological evidence of cervical myelopathy who were suitable for cervical disc replacement from 2007 to 2009 were included. Implants were inserted by one of two consultant surgeons {IMS, MO’M}. Patients were assessed preoperatively and at six, 12 and 24 months, postoperatively, with a visual analogue score (VAS) for neck and arm pain severity and frequency, the Neck Disability Index questionnaire (NDI) and the Centre for Epidemiologic Studies Depression questionnaire (CES-D). Results: Ten patients underwent surgery between May 2007 and July 2009, 6 women, and 4 men. Average age was 54 years (40-64). Disc levels replaced were: four at C4-5; eight at C5-6; seven at C6-7. Three patients had one disc replaced, five patients had two discs replaced, and two patients had three discs replaced. The VAS for neck pain improved from 5.9 pre-operatively to 1.4-24 months postoperatively and the VAS arm pain improved from 5.4 to 2.6. The NDI improved from 51% preoperatively to 26.8% at 24 months postoperatively. The CES-D showed a slight increase from 19.5 preoperatively to 21.7 at 24 months, postoperatively. Conclusion: Cervical decompression and disc replacement improves pain and function in patients with cervical myelopathy. This benefit is maintained at 24 months post op, with no cases requiring revision. PMID:23125494

    The 3M Company manufactures a silvered acrylic film called ECP-305 that is regarded as the preferred reflective film for use on stretched-membrane heliostats. However, ECP-305 will degrade in time, due to both corrosion of the silver layer and delamination at the film's silver-to-acrylic interface, and will eventually need to be replaced. 3M uses a very aggressive adhesive on this film, and once it is laminated, replacement is very difficult. The purpose of this investigation was the development of a replaceable reflector, a reflective film that can be easily removed and replaced. A replaceable reflector was successfully configured by laminating ECP-305 to the top surface of a smooth, dimensionally stable polymer film, with a removable adhesive applied to the underside of the polymer film. Several stages of screening and testing led to the selection of a 0.010-inch thick polycarbonate (GE 8030) as the best polymer film and a medium tack tape (3M Y-9425) was selected as the best removable adhesive. To demonstrate the feasibility of the replaceable reflector concept and to provide a real-time field test, the chosen construction was successfully applied to the 50-m{sup 2} SKI heliostat at the Central Receiver Test Facility at Sandia National Laboratories in Albuquerque. 4 refs., 13 figs., 7 tabs.

    Deprivation correlates with poor health and psychosocial variables can affect the symptoms of knee arthritis. Our aim was to determine the effect of deprivation on the level of knee function and health-related quality of life at the time of arthroplasty and 12 months after total knee replacement. From our database of over 2500 knee replacements, we analysed both clinical and quality of life outcome measures. We analysed the relationship between deprivation (by Townsend score), knee function (Knee Society Score) and health-related quality of life (Nottingham Health Profile) before total knee replacement (TKR) and at 12 months post-operation. There was no significant correlation between Townsend score, Knee Society Score and Nottingham Health Profile preoperatively or at 12 months after knee replacement, thus showing that there was no association between deprivation and the severity of knee arthritis at the time of joint replacement nor was there a relationship between deprivation and the short-term outcome from total knee replacement.

    Ion replacement electrorefining is an innovative electrochemical approach to purifying and separating metals. This approach overcomes the shortcomings of conventional electrorefining and has the potential for processing a wider range of metals and metal halide salts. Salt waste is also minimized with this approach. The key element of ion replacement electrorefining is the ion replacement electrode. This electrode allows a decoupling of the electrotransport process into two separate steps, anodic dissolution and cathodic deposition. Three key accomplishments described in this report that demonstrate the feasibility of ion replacement electrorefining are: (1) we have identified a suitable sodium/{beta}{double_prime}-alumina/molten salt electrolyte system that functions reproducibly at 723 K, (2) we have oxidized and deposited dysprosium, lanthanum, uranium, and titanium by using a sodium ion replacement electrode. In several experiments, an actual separation of dysprosium and lanthanum was observed, and (3) we have identified a metal alloy, Li{sub x}Sb, as an alternative ion replacement electrode. The next stage in the program is the design, construction, and testing of a laboratory-scale electrorefiner. Follow-on development with funding from industrial and federal sponsors is being pursued.

    The Department of Veterans Affairs (VA) amends its regulations concerning veterans in need of service dogs. Under this final rule, VA will provide to veterans with visual, hearing, or mobility impairments benefits to support the use of a service dog as part of the management of such impairments. The benefits include assistance with veterinary care, travel benefits associated with obtaining and training a dog, and the provision, maintenance, and replacement of hardware required for the dog to perform the tasks necessary to assist such veterans.

    Many hospital administrators and boards of directors, having overcome their initial opposition to advertising and hired a marketing professional, are wondering why their marketing programs have not accomplished all that they had hoped. The answer lies in their perception of who is responsible for marketing. Marketing is not a specialty separate from the disciplines of management--it is a basic management skill. Its goal is to satisfy the customer by providing products and services that meet the customer's needs, wants, and preferences. Line managers must understand the hospital's customers and make the critical day-to-day differences in satisfying them. They are the hospital's front-line marketers, and the marketing department's role is to support them in this function. The marketing department should develop the line managers' marketing skills by furnishing them with the appropriate tools: formats, models, examples, and instructions. In addition, the marketing staff should provide such specialized services as marketing research, ad agency management, and development of communications. PMID:10277616

    Although there has been a dramatic increase in NCI use over the last decade, there is a wide variation in NCI design procedures, procurement specifications, installation and handling practices, live working techniques, and inspection and maintenance methods. Consequently, practicing utility engineers need a source of relevant information and recommendations on these subjects. EPRI has responded to this need by investing in a major multiyear research program on NCI. This report provides guidelines for electric utilities considering the use of non-ceramic insulators (NCI). It includes information on new installations, the replacement of conventional porcelain or glass (ceramic) insulators with NCI on existing transmission lines, and the assessment of NCI in service on transmission lines.

    Many life-history traits are expressed interactively in life, but to a varying extent on different occasions. Changes in trait expression can be accounted for by differences in the quality of the environment ('environmental constraint' hypothesis) or by strategic adjustments, if the relative contribution of the trait to fitness varies with time ('strategic allocation' hypothesis). In birds, egg production is lower in replacement clutches than in first clutches, but it is unknown whether this reduction results from an environmental constraint (e.g. food being less available at the time when the replacement clutch is produced) or from a strategic allocation of resources between the two breeding attempts. To distinguish between these two hypotheses, we performed an experiment with black-legged kittiwakes (Rissa tridactyla). Pairs were either food-supplemented or not before the first clutch was laid onwards and we induced them to produce a replacement clutch by removing eggs once when the first clutch was complete. As predicted by the 'strategic allocation' hypothesis, egg production of food-supplemented and non-food-supplemented birds decreased between first and replacement clutches. This suggests that kittiwakes strategically reduce investment in egg production for their replacement clutches compared to first clutches. ?? 2006 The Royal Society.

  6. Managing the replacement cycle of laser inventory.

    Medical lasers are quickly moving into the replacement phase of technology management. Barnes Hospital (St. Louis, MO) is using its laser team to define a process of planned laser replacement using the experience gained from traditional medical equipment replacement cycles, quality improvement principles and tools, and other formalized interdisciplinary teams. The process described in this paper has six basic steps: (1) A decision is made to request a replacement laser. (2) An appropriation request form is completed and submitted with the clinical and/or technical justifications. (3) Those requests initiated outside of the Clinical Engineering Department are reviewed by the Clinical Engineer/Medical Laser Safety Officer (CE/MLSO). (4) The CE/MLSO presents the requests to the hospital Laser Committee, and (5) then to the Laser Users' Group. (6) Finally, an Expenditure Authorization Committee reviews all capital expense requests, including those for replacement lasers, and allocates funds for the next fiscal year. This paper illustrates and evaluates the process, using an example from the review process for 1993 equipment purchases at Barnes Hospital. PMID:10124683

  7. Technology management: a perspective on system support, procurement, and replacement planning.

    The escalating costs associated with medical technology present a host of challenges for the hospital clinical engineering department. As service and support costs comprise ever larger portions of a system's life cycle cost, innovative management of service provider mix and mechanisms can provide substantial savings in operating expenses. In addition to full-service contracts, the use of demand service and independents has become commonplace. Medical equipment maintenance insurance programs provide yet another service alternative, combining the flexibility of demand service with the safety of a capped budget. These programs have gained acceptance among hospitals as their providers have become more focused on the healthcare market and its many needs. In view of the long-term cost impact surrounding technology procurement, the authors recommend that hospitals refine system evaluation methodologies and develop more comprehensive techniques directed at capital equipment replacement planning. One replacement planning approach, based on an estimation of system value changes, is described and illustrated using data collected through client consultations. Although the validity of this method has not been demonstrated, it represents a simplified approach to life cycle cost analysis and is intended to provide a standard method by which system replacement planning may be quantified. As a departure from system devaluation based solely on depreciation, this method estimates prospective system values derived from anticipated operations and maintenance costs, projected revenue, and the availability of new technology.

  8. Rethinking Lean Service

    Ever since Levitt's influential Harvard Business Review article 'Production-Line Approach to Service' was published in 1972, it has been common for services to be treated like production lines in both the academic literature and more widely in management practice. The belief that achieving economies of scale will reduce unit costs is a common feature of management decision-making. As technological advancement has produced ever more sophisticated IT and telephony, it has become increasingly easier for firms to standardise and off-shore services. The development of the 'lean' literature has only helped to emphasise the same underlying management assumptions: by managing cost and workers' activity, organisational performance is expected to improve. This chapter argues that through misinterpretation of the core paradigm 'lean' has become subsumed into the 'business as usual' of conventional service management. As a result, 'lean' has become synonymous with 'process efficiency' and the opportunity for significant performance improvement - as exemplified by Toyota - has been missed.
