We focus on automatic strategies to optimize life cycle savings and investment. Classical optimal savings theory establishes that, given the level of risk aversion, a saver would keep the same relative amount invested in risky assets at any given time. We show that, when optimizing lifecycle investment, performance and risk assessment have to take into account the investor's risk aversion and the maximum amount the investor could lose, simultaneously. When risk aversion and maximum possible loss are considered jointly, an optimal savings strategy is obtained, which follows from constant rather than relative absolute risk aversion. This result is fundamental to prove that if risk aversion and the maximum possible loss are both high, then holding a constant amount invested in the risky asset is optimal for a standard lifetime saving/pension process and outperforms some other simple strategies. Performance comparisons are based on downside risk-adjusted equivalence that is used in our illustration. PMID:24711728

Hip fracture is common in older adults and is associated with high morbidity, mortality and significant health care costs. A pilot orthogeriatrics service was established in an acute hospital. We aimed to establish the cost effectiveness of this service. Length of hospital stay, discharge destination and rehabilitation requirements were analysed for a one year period and compared to patients who received usual care prior to the service. We calculated the costs incurred and savings produced by the orthogeriatric service. Median length of stay was reduced by 3 days (p < 0.001) saving €266,976. There was a 19% reduction in rehabilitation requirements saving €192,600. Median rehabilitation length of stay was reduced by 6.5 days saving €171,093. Reductions in long term care requirements led to savings of €10,934 per week. Costs to establish such a service amount to €171,564. The introduction of this service led to improved patient outcomes in a cost effective manner.

Comparative study of irrigation water use and groundwater recharge under various irrigation schemes in an agricultural region, central Taiwan

The risk of rice production has increased notably due to climate change in Taiwan. To respond to growing agricultural water shortage without affecting normal food production in the future, the application of water-saving irrigation will be a substantial resolution. However, the adoption of water-saving irrigation may result in the reducing of groundwater recharge because continuous flooding in the paddy fields could be regarded as an important source for groundwater recharge. The aim of this study was to evaluate the irrigation water-saving benefit and groundwater recharge deficit when adopting the System of Rice Intensification, known as SRI methodology, in the Choushui River alluvial fan (the largest groundwater pumping and the most important rice-cropping region in central Taiwan). The three-dimensional finite element groundwater model, FEMWATER, was applied to simulate the infiltration process and groundwater recharge under SRI methodology and traditional irrigation schemes including continuous irrigation, and rotational irrigation in two rice-crop periods with hydro-climatic data of 2013. The irrigation water use was then calculated by water balance. The results showed that groundwater recharge amount of SRI methodology was slightly lower than those of traditional irrigation schemes, reduced 3.6% and 1.6% in the first crop period, and reduced 3.2% and 1.6% in the second crop period, compared with continuous irrigation and rotational irrigation, respectively. However, the SRI methodology achieved notably water-saving benefit compared to the disadvantage of reducing the groundwater recharge amount. The field irrigation requirement amount of SRI methodology was significantly lower than those of traditional irrigation schemes, saving 37% and 20% of irrigation water in the first crop period, and saving 53% and 35% in the second crop period, compared with continuous irrigation and rotational irrigation, respectively. Therefore, the amount of groundwater pumping for irrigation water use can be reduced when adopting the SRI methodology in the future. The reducing of groundwater recharge could be supplemented by using 1,500 hectares of fallow paddy fields, located at proximal-fan region, as recharge pools in the wet season. The adoption of water-saving irrigation would be helpful for the relevant government agency to formulate the integral water resource management strategies in this region.

The field study is planned to continue through the 2016 cooling season with the draft final project report due by September 30, 2016. This report provides a description of both installations and preliminary 2015 cooling and fall season performance results for the Knoxville site. For the August 18 through December 14 period, the Knoxville site GS-IHP provided 53.6% total source energy savings compared to a baseline electric RTU/heat pump and electric WH. Peak demand savings ranged from 33% to 59% per month. Energy cost savings of 53.1% have been achieved to date with more than half of that coming frommore » reduced demand charges. Data on installation and maintenance costs are being collected and will be combined with total test period energy savings data for a payback analysis to be included in the project final report. The GS-IHP also saved a significant amount of carbon emissions. The total emission savings for the Knoxville site for the August-December 2015 period were ~0.8 metric tons. If trading for carbon credits ever becomes a reality, additional cost savings would be realized.« less

Electrically switchable broadband infrared reflectors that are relatively transparent in the visible region have been fabricated using polymer stabilised cholesteric liquid crystals. The IR reflectors can change their reflection/transmission properties by applying a voltage in response to changes in environmental conditions. Simulations predict that a significant amount of energy can be saved on heating, cooling and lighting of buildings in places such as Madrid by using this switchable IR reflector. We have also fabricated a switchable IR reflector which can also generate electricity. These polymer based switchable IR reflectors are of high potential as windows of automobiles and buildings to control interior temperatures and save energy.

Circadian rhythm disruptions may have harmful impacts on health. Circadian rhythm disruptions caused by jet lag compromise the quality and amount of sleep and may lead to a variety of symptoms such as fatigue, headache, and loss of attention and alertness. Even a minor change in time schedule may cause considerable stress for the body. Transitions into and out of daylight saving time alter the social and environmental timing twice a year. According to earlier studies, this change in time-schedule leads to sleep disruption and fragmentation of the circadian rhythm. Since sleep deprivation decreases motivation, attention, and alertness, transitions into and out of daylight saving time may increase the amount of accidents during the following days after the transition. We studied the amount of road traffic accidents one week before and one week after transitions into and out of daylight saving time during years from 1981 to 2006. Our results demonstrated that transitions into and out of daylight saving time did not increase the number of traffic road accidents. PMID:20652036

The purpose of this investigation was to determine the cost-saving potential of a simple screen-and-treat program for vaginal infection, which has previously been shown to lead to a reduction of 50% in the rate of preterm births. To determine the potential cost savings, we compared the direct costs of preterm delivery of infants with a birth weight below 1900g with the costs of the screen-and-treat program. We used a cut-off birth weight of 1900g because, in our population, all infants with a birth weight below 1900g were transferred to the neonatal intensive care unit. The direct costs associated with preterm delivery were defined to include the costs of the initial hospitalization of both mother and infant and the costs of outpatient follow-up throughout the first 6 years of life of the former preterm infant. The costs of the screen-and-treat program were defined to include the costs of the screening examination and the resulting costs of antimicrobial treatment and follow-up. All calculations were based on health-economic data obtained in the metropolitan area of Vienna, Austria. The number of preterm infants with a birth weight below 1900g was 12 (0.5%) in the intervention group (N=2058) and 29 (1.3%) in the control group (N=2097). The direct costs per preterm birth were found to amount to EUR (euro) 60262. Overall, the expected total savings in direct costs achieved by the screen-and-treat program and the ensuing 50% reduction in the number preterm births with a birth weight below 1900g amounted to more than euro 11 million. The costs of screening and treatment were found to amount to merely 7% of the direct costs saved as a result of the screen-and-treat program. A simple preterm prevention program, consisting of screening and antimicrobial treatment and follow-up of women with asymptomatic vaginal infection, leads not only to a significant reduction in the rate of preterm births but also to substantial savings in the direct costs associated with prematurity.

INTRODUCTION There is a growing trend to use alcohol-based hand disinfectants in clinical practice. In addition to their antibacterial efficacy, these disinfectants offer an alternative to traditional surgical hand disinfection agents that can save water in the operating theatre. MATERIALS AND METHODS The amounts of water and soap used during traditional surgical hand disinfection with antiseptic soap preparations were measured and water usage over a 1-year period was estimated. Costs of traditional disinfection agents were compared with alcohol-based agents. RESULTS One surgical hand disinfection episode with traditional agents used 18.5 l of water. During 15,500 procedures performed at our institution over a 1-year period, 931,938 l of water were used which could have been saved had alcohol-based agents been used. Cost per episode of hand disinfection depends on the amounts used and is not higher compared to traditional agents. CONCLUSIONS The benefits of using an alcohol-based surgical hand disinfectant may include significant water savings, in addition to previously published advantages of improved efficacy. When deciding on the method of surgical hand disinfection, careful thought should be given to the use of water as a resource. Surgeons should be aware of the environmental impact of their profession.

Occupancy sensor systems are gaining traction as an effective technological approach to reducing energy use in exterior commercial lighting applications. Done correctly, occupancy sensors can substantially enhance the savings from an already efficient lighting system. However, this technology is confronted by several potential challenges and pitfalls that can leave a significant amount of the prospective savings on the table. This report describes anecdotal experiences from field installations of occupancy sensor controlled light-emitting diode (LED) lighting at two parking structures and two parking lots. The relative levels of success at these installations reflect a marked range of potential outcomes: from anmore » additional 76% in energy savings to virtually no additional savings. Several issues that influenced savings were encountered in these early stage installations and are detailed in the report. Ultimately, care must be taken in the design, selection, and commissioning of a sensor-controlled lighting installation, else the only guaranteed result may be its cost.« less

Durst, Louise A.; Carlsen, John; Kuchinski, Megan; Harner, Lauren; Neves, Daniel; Harris, Stephanie J.; Traiger, Glenna L.

2012-01-01

Background The management of patients with pulmonary arterial hypertension (PAH) requires extensive coordination between patients, their support system, third-party payers, and healthcare professionals. For patients with PAH who are receiving endothelin receptor antagonists (ERAs), such cross-stakeholder coordination was needed to ensure compliance with a US Food and Drug Administration (FDA) Risk Evaluation and Mitigation Strategy (REMS) requirement for monthly liver function tests (LFTs). In March 2011, the FDA removed this requirement for ambrisentan (Letairis) in conjunction with a change to the product label. Objective This study sought to explore the impact of the ambrisentan label change on payers, providers who treat PAH, and specialty pharmacies. Methods This study, conducted in June and July 2011, involved telephone interviews with 5 medical/pharmacy directors in commercial health plans (representing 78,345,000 covered lives collectively); written surveys and telephone interviews with 6 nurses managing patients with PAH; and written surveys and telephone interviews with 4 staff members from specialty pharmacies to determine direct and indirect cost-savings associated with the removal of the monthly LFT requirement for ambrisentan. Qualitative telephone interviews with payer decision makers informed the cost-savings for payers. Direct cost-savings were calculated from the responses of the nurses managing PAH regarding the prescribing trends of their practices and the frequency of LFTs. Indirect cost-savings were calculated using time-savings data collected from the PAH-managing nurses and the specialty pharmacy staff, as well as from the US Bureau of Labor Statistics data regarding national wage averages for the respective staff. Results: Payers reported that REMS requirements did not play a large role in their plan's coverage or management of ERAs; although direct cost-savings resulting from the label change were an estimated $28 per patient per month, this amount is relatively small compared with the overall cost of PAH treatment for payers. The impact of the ambrisentan label change was more significant for providers and specialty pharmacies. The label change resulted in a significant, average 69% reduction in the frequency of LFTs for patients using ambrisentan. The average monthly time-savings realized by providers as a result of the label change was 12 minutes per patient receiving ambrisentan, and the average monthly direct and indirect cost-savings totaled $10.75 and $29.75, respectively, per patient taking ambrisentan. Telephone interviews with specialty pharmacies indicated that the average monthly time-savings for the 4 specialty pharmacies surveyed was 14 minutes per patient using ambrisentan, representing an 86.7% decrease in the amount of time specialty pharmacies spent on LFT-related administrative tasks for patients using ambrisentan. Conclusion Findings from this study indicate that the ambrisentan label change significantly reduced the number of LFTs for patients with PAH, resulting in time-savings or cost-savings for payers, providers, and specialty pharmacies.

A purported benefit of digital imaging and archiving of radiographic procedures is the presumption of time savings to radiologists, radiology technologists, and radiology departmentpersonnel involved with processingfilms and managing theflimfile room. As part of the University of Washington's evaluation of Picture Archiving and Communication Systems (PACS)for the U.S. Army Medical Research and Development Command, a study was performed which evaluated the current operationalpractices of the film-based radiology department at the University of Washington Medical Center (UWMC). Industrial engineering time and motion studies were conducted to document the length of time requiredforfilm processing in various modalities, the proportion of the total exam time usedforfilm processing, the amount of time radiologists spent searchingfor and looking at images, and the amount of time file room personnel spent collating reports, making loans, updatingfilm jacket information, and purging files. This evaluation showed that better than one-half of the tasks in the file room may be eliminated with PACS and radiologists may save easily 10 percent of the time they spend reading films by no longer having to searchforfilms. Radiology technologists may also save as much as 10 percent of their time with PACS, although this estimate is subject to significant patient mix aberrations and measurement error. Given that the UWMC radiology department operates efficiently, similar improvements are forecast for other radiology departments and larger improvements areforecastfor less efficient departments.

Energy and Economic Impacts of U.S. Federal Energy and Water Conservation Standards Adopted From 1987 Through 2015

DOE Office of Scientific and Technical Information (OSTI.GOV)

Meyers, Stephen; Williams, Alison; Chan, Peter

This paper presents estimates of the key impacts of Federal energy and water conservation standards adopted from 1987 through 2015. The standards for consumer products and commercial and industrial equipment include those set by legislation as well as standards adopted by DOE through rulemaking. In 2015, the standards saved an estimated 4.49 quads of primary energy, which is equivalent to 5% of total U.S. energy consumption. The savings in operating costs for households and businesses totaled $63.4 billion. The average household saved $320 in operating costs as a result of residential appliance standards. The estimated reduction in CO2 emissions associatedmore » with the standards in 2015 was 238 million metric tons, which is equivalent to 4.3% of total U.S. CO2 emissions. The estimated cumulative energy savings over the period 1990-2090 amount to 216.9 quads. Accounting for the increased upfront costs of more-efficient products and the operating cost (energy and water) savings over the products’ lifetime, the standards have a cumulative net present value (NPV) of consumer benefit of between $1,627 billion and $1,887 billion, using 7 percent and 3 percent discount rates, respectively. The water conservation standards, together with energy conservation standards that also save water, reduced water use by 1.9 trillion gallons in 2015 and estimated cumulative water savings by 2090 amount to 55 trillion gallons. The estimated consumer savings in 2015 from reduced water use amounted to $12 billon.« less

Costs and benefits of bicycling investments in Portland, Oregon.

Gotschi, Thomas

2011-01-01

Promoting bicycling has great potential to increase overall physical activity; however, significant uncertainty exists with regard to the amount and effectiveness of investment needed for infrastructure. The objective of this study is to assess how costs of Portland's past and planned investments in bicycling relate to health and other benefits. Costs of investment plans are compared with 2 types of monetized health benefits, health care cost savings and value of statistical life savings. Levels of bicycling are estimated using past trends, future mode share goals, and a traffic demand model. By 2040, investments in the range of $138 to $605 million will result in health care cost savings of $388 to $594 million, fuel savings of $143 to $218 million, and savings in value of statistical lives of $7 to $12 billion. The benefit-cost ratios for health care and fuel savings are between 3.8 and 1.2 to 1, and an order of magnitude larger when value of statistical lives is used. This first of its kind cost-benefit analysis of investments in bicycling in a US city shows that such efforts are cost-effective, even when only a limited selection of benefits is considered.

Chen, Shih-Kai; Jang, Cheng-Shin; Tsai, Cheng-Bin

2015-04-01

To respond to agricultural water shortage impacted by climate change without affecting rice yield in the future, the application of water-saving irrigation, such as SRI methodology, is considered to be adopted in rice-cultivation in Taiwan. However, the flooded paddy fields could be considered as an important source of groundwater recharge in Central Taiwan. The water-saving benefit of this new methodology and its impact on the reducing of groundwater recharge should be integrally assessed in this area. The objective of this study was to evaluate the changes of groundwater recharge/ irrigation water use between the SRI and traditional irrigation schemes (continuous irrigation, rotational irrigation). An experimental paddy field located in the proximal area of the Choushui River alluvial fan (the largest groundwater pumping region in Taiwan) was chosen as the study area. The 3-D finite element groundwater model (FEMWATER) with the variable boundary condition analog functions, was applied in simulating groundwater recharge process and amount under traditional irrigation schemes and SRI methodology. The use of effective rainfall was taken into account or not in different simulation scenarios for each irrigation scheme. The simulation results showed that there were no significant variations of infiltration rate in the use of effective rainfall or not, but the low soil moisture setting in deep soil layers resulted in higher infiltration rate. Taking the use of effective rainfall into account, the average infiltration rate for continuous irrigation, rotational irrigation, and SRI methodology in the first crop season of 2013 were 4.04 mm/day, 4.00 mm/day and 3.92 mm/day, respectively. The groundwater recharge amount of SRI methodology was slightly lower than those of traditional irrigation schemes, reducing 4% and 2% compared with continuous irrigation and rotational irrigation, respectively. The field irrigation requirement amount of SRI methodology was significantly lower than those of traditional irrigation schemes, saving 35% and 9% compared with continuous irrigation and rotational irrigation, respectively. The SRI methodology significantly improved water-saving benefit compared with the disadvantage of reducing groundwater recharge. The results could be used as a basis for the relevant government agency to formulate the integral water resource management strategies in this area.

Goalkeepers have a very important role in handball. In coaching communities it is well recognized that goalkeepers’ performances can predict team ranking in major tournaments. Despite this, few studies have been conducted on elite goalkeepers participating in World Championships. Therefore, the purpose of this study was to analyse goalkeepers’ save performance during the 88 matches of the 2015 men’s World Championships tournament. Goalkeepers from 24 national teams were analysed using a tracking camera system and bespoke software (Prozone Handball V.1.2, Prozone, Leeds, UK). The purpose of this study was to examine time-motion performance parameters and to evaluate the save rates for each goalkeeper. The mean total distance covered in a game by the goalkeepers was 1634±999 m. Goalkeepers spent most of the time walking or standing. The total amount of shots to the goal was 6893, with a mean save percentage of 30% (2088 saves). A significant relationship was identified between the goalkeepers’ save statistics and the final team rankings. The save rate is important for teams to achieve a higher ranking, and therefore the selection and training of goalkeepers requires more than just assessing physical abilities. The throwing distribution and success/save rate during the Qatar 2015 Men Handball World Championships suggest strong and weak parts of the goal area, and coaches can use this information to adjust their training approaches for both goalkeepers and shooters.

VA Telemedicine: An Analysis of Cost and Time Savings.

PubMed

Russo, Jack E; McCool, Ryan R; Davies, Louise

2016-03-01

The Veterans Affairs (VA) healthcare system provides beneficiary travel reimbursement ("travel pay") to qualifying patients for traveling to appointments. Travel pay is a large expense for the VA and hence the U.S. Government, projected to cost nearly $1 billion in 2015. Telemedicine in the VA system has the potential to save money by reducing patient travel and thus the amount of travel pay disbursed. In this study, we quantify this savings and also report trends in VA telemedicine volumes over time. All telemedicine visits based at the VA Hospital in White River Junction, VT between 2005 and 2013 were reviewed (5,695 visits). Travel distance and time saved as a result of telemedicine were calculated. Clinical volume in the mental health department, which has had the longest participation in telemedicine, was analyzed. Telemedicine resulted in an average travel savings of 145 miles and 142 min per visit. This led to an average travel payment savings of $18,555 per year. Telemedicine volume grew significantly over the study period such that by the final year the travel pay savings had increased to $63,804, or about 3.5% of the total travel pay disbursement for that year. The number of mental health telemedicine visits rose over the study period but remained small relative to the number of face-to-face visits. A higher proportion of telemedicine visits involved new patients. Telemedicine at the VA saves travel distance and time, although the reduction in travel payments remains modest at current telemedicine volumes.

A mobile asset sharing policy for hospitals with real time locating systems.

2016-01-01

Each year, hospitals lose a considerable amount of time and money due to misplaced mobile assets. In addition the assets which remain in departments that frequently use them depreciate early, while other assets of the same type in different departments are rarely used. A real time locating system can prevent these losses when used with appropriate asset sharing policies. This research quantifies the amount of time a medium size hospital saves by using real time locating system and proposes an asset selection rule to eliminate the asset usage imbalance problem. The asset selection rule proposed is based on multi objective optimization techniques. The effectiveness of this rule on asset to patient time and asset utilization rate variance performance measures were tested using discrete event simulation method. Results show that the proposed asset selection rule improved the usage balance significantly. Sensitivity analysis showed that the proposed rule is robust to changes in demand rates and user preferences. Real time locating systems enable saving considerable amount of time in hospitals, and they can still be improved by integrating decision support mechanisms. Combining tracking technology and asset selection rules helps improve healthcare services.

Analysis of Multi-Flight Common Routes for Traffic Flow Management

NASA Technical Reports Server (NTRS)

Sheth, Kapil; Clymer, Alexis; Morando, Alex; Shih, Fu-Tai

2016-01-01

This paper presents an approach for creating common weather avoidance reroutes for multiple flights and the associated benefits analysis, which is an extension of the single flight advisories generated using the Dynamic Weather Routes (DWR) concept. These multiple flight advisories are implemented in the National Airspace System (NAS) Constraint Evaluation and Notification Tool (NASCENT), a nation-wide simulation environment to generate time- and fuel-saving alternate routes for flights during severe weather events. These single flight advisories are clustered together in the same Center by considering parameters such as a common return capture fix. The clustering helps propose routes called, Multi-Flight Common Routes (MFCR), that avoid weather and other airspace constraints, and save time and fuel. It is expected that these routes would also provide lower workload for traffic managers and controllers since a common route is found for several flights, and presumably the route clearances would be easier and faster. This study was based on 30-days in 2014 and 2015 each, which had most delays attributed to convective weather. The results indicate that many opportunities exist where individual flight routes can be clustered to fly along a common route to save a significant amount of time and fuel, and potentially reducing the amount of coordination needed.

The North China Plain, with a population of approximately 150 million, is facing severe water scarcity. The over-exploitation of groundwater in the region, with accumulation amounts reaching more than 150 billion m 3 , causes a series of hydrological and geological problems together with the consumption of a significant amount of energy. Here, we highlight the energy and greenhouse gas-related environmental co-benefits of the South-to-North Water Diversion Project (SNWDP). Moreover, we evaluate the energy-saving effect of SNWDP on groundwater exploitation based on the groundwater-exploitation reduction program implemented by the Chinese government. Our results show that the transferred water will replace about 2.97 billion m 3 of exploited groundwater in the water reception area by 2020 and hence reduce energy consumption by 931 million kWh. Further, by 2030, 6.44 billion m 3 of groundwater, which accounts for 27% of the current groundwater withdrawal, will save approximately 7% of Beijing's current thermal power generation output.

Improving energy efficiency of Embedded DRAM Caches for High-end Computing Systems

DOE Office of Scientific and Technical Information (OSTI.GOV)

Mittal, Sparsh; Vetter, Jeffrey S; Li, Dong

2014-01-01

With increasing system core-count, the size of last level cache (LLC) has increased and since SRAM consumes high leakage power, power consumption of LLCs is becoming a significant fraction of processor power consumption. To address this, researchers have used embedded DRAM (eDRAM) LLCs which consume low-leakage power. However, eDRAM caches consume a significant amount of energy in the form of refresh energy. In this paper, we propose ESTEEM, an energy saving technique for embedded DRAM caches. ESTEEM uses dynamic cache reconfiguration to turn-off a portion of the cache to save both leakage and refresh energy. It logically divides the cachemore » sets into multiple modules and turns-off possibly different number of ways in each module. Microarchitectural simulations confirm that ESTEEM is effective in improving performance and energy efficiency and provides better results compared to a recently-proposed eDRAM cache energy saving technique, namely Refrint. For single and dual-core simulations, the average saving in memory subsystem (LLC+main memory) on using ESTEEM is 25.8% and 32.6%, respectively and average weighted speedup are 1.09X and 1.22X, respectively. Additional experiments confirm that ESTEEM works well for a wide-range of system parameters.« less

Energy savings opportunity survey at Walter Reed Army Medical Center, Washington, DC. Final Submittal report

1987-10-22

This Energy Savings Opportunity Survey (ESOS) was performed for sixteen (16) buildings at Walter Reed Army Medical Center (WPAMC) in Washington, D.C. This survey was intended to reevaluate and update projects from a previous Energy Engineering Analysis Program (EEAP) survey performed at WRAMC. However, the previous EEAP survey was determined by the contracting officer to be incomplete and not worthy of further consideration. Therefore, this survey involved the complete reevaluation of the buildings to determine their potential energy cost savings. Six (6) projects and nine (9) low cost/no cost energy conservation opportunities (ECO`s) are recommended for implementation in the buildings.more » These projects and ECO`s are projected to annually save $448,263 at an implementation cost of $891,659. The simple payback (i.e., implementation cost divided by cost savings) for the recommendations in the survey is 1.99 years. The two (2) projects with the greatest cost savings are a stack heat recovery system (Project Number 5) and HVAC modifications (Project Number 1). These two (2) projects will provide 67% of the projected total savings for the survey. The sixteen (16) buildings in this survey represent only 22% of the total floor area of the Walter Reed Army Medical Center complex. It is believed that significant potential energy cost savings amounting to two (2) million dollars may be achieved in the remaining buildings in the complex not included in this survey. Specifically it is believed the main hospital building contains many opportunities for substantial cost savings.« less

To compare refractive outcomes, contrast sensitivity, higher-order aberrations (HOAs), and patient satisfaction after photorefractive keratectomy for correction of moderate myopia with two methods: tissue saving versus wavefront optimized. In this prospective, comparative study, 152 eyes (80 patients) with moderate myopia with and without astigmatism were randomly divided into two groups: the tissue-saving group (Technolas 217z Zyoptix laser; Bausch & Lomb, Rochester, NY) (76 eyes of 39 patients) or the wavefront-optimized group (WaveLight Allegretto Wave Eye-Q laser; Alcon Laboratories, Inc., Fort Worth, TX) (76 eyes of 41 patients). Preoperative and 3-month postoperative refractive outcomes, contrast sensitivity, HOAs, and patient satisfaction were compared between the two groups. The mean spherical equivalent was -4.50 ± 1.02 diopters. No statistically significant differences were detected between the groups in terms of uncorrected and corrected distance visual acuity and spherical equivalent preoperatively and 3 months postoperatively. No statistically significant differences were seen in the amount of preoperative to postoperative contrast sensitivity changes between the two groups in photopic and mesopic conditions. HOAs and Q factor increased in both groups postoperatively (P = .001), with the tissue-saving method causing more increases in HOAs (P = .007) and Q factor (P = .039). Patient satisfaction was comparable between both groups. Both platforms were effective in correcting moderate myopia with or without astigmatism. No difference in refractive outcome, contrast sensitivity changes, and patient satisfaction between the groups was observed. Postoperatively, the tissue-saving method caused a higher increase in HOAs and Q factor compared to the wavefront-optimized method, which could be due to larger optical zone sizes in the tissue-saving group.

Integrating the Clearance in NPP Residual Material Management

DOE Office of Scientific and Technical Information (OSTI.GOV)

Garcia-Bermejo, R.; Lamela, B.

Previous Experiences in decommissioning projects are being used to optimize the residual material management in NPP, metallic scrap usually. The approach is based in the availability of a materials Clearance MARSSIM-based methodology developed and licensed in Spain. A typical project includes the integration of segregation, decontamination, clearance, quality control and quality assurance activities. The design is based in the clearance methodology features translating them into standard operational procedures. In terms of ecological taxes and final disposal costs, significant amounts of money could be saved with this type of approaches. The last clearance project managed a total amount of 405 tonsmore » scrap metal and a similar amount of other residual materials occupying a volume of 1500 m{sup 3}. After less than a year of field works 251 tons were finally recycled in a non-licensed smelting facility. The balance was disposed as LILW. In the planning phase the estimated cost savings were 4.5 Meuro. However, today a VLLW option is available in European countries so, the estimated cost savings are reduced to 1.2 Meuro. In conclusion: the application of materials clearance in NPP decommissioning lessons learnt to the NPP residual material management is an interesting management option. This practice is currently going on in Spanish NPP and, in a preliminary view, is consistent with the new MARSAME Draft. An interesting parameter is the cost of 1 m3 of recyclable scrap. The above estimates are very project specific because in the segregation process other residual materials were involved. If the effect of this other materials is removed the estimated Unit Cost were in this project around 1700 euro/m{sup 3}, this figure is clearly below the above VLLW disposal cost of 2600 euro. In a future project it appears feasible to descend to 839 euro/m{sup 3} and if it became routine values and is used in big Decommissioning projects, around 600 euro/m{sup 3} or below possibly could be achieved. A rough economical analysis permits to estimate a saving around 2000 US$ to 13000 US$ per cubic meter of steel scrap according the variability of materials and disposal costs. Many learnt lessons of this practice were used as a feed back in the planning of characterization activities for decommissioning a Spanish NPP and today are considered as a significant reference in our Decommissioning engineering approaches.« less

Hybrid Power Management for Office Equipment

NASA Astrophysics Data System (ADS)

Gingade, Ganesh P.

Office machines (such as printers, scanners, fax, and copiers) can consume significant amounts of power. Few studies have been devoted to power management of office equipment. Most office machines have sleep modes to save power. Power management of these machines are usually timeout-based: a machine sleeps after being idle long enough. Setting the timeout duration can be difficult: if it is too long, the machine wastes power during idleness. If it is too short, the machine sleeps too soon and too often--the wakeup delay can significantly degrade productivity. Thus, power management is a tradeoff between saving energy and keeping short response time. Many power management policies have been published and one policy may outperform another in some scenarios. There is no definite conclusion which policy is always better. This thesis describes two methods for office equipment power management. The first method adaptively reduces power based on a constraint of the wakeup delay. The second method is a hybrid with multiple candidate policies and it selects the most appropriate power management policy. Using six months of request traces from 18 different offices, we demonstrate that the hybrid policy outperforms individual policies. We also discover that power management based on business hours does not produce consistent energy savings.

Beer, Wood, and Welfare ‒ The Impact of Improved Stove Use Among Dolo-Beer Breweries

PubMed Central

2015-01-01

Local beer breweries in Burkina Faso absorb a considerable amount of urban woodfuel demand. We assess the woodfuel savings caused by the adoption of improved brewing stoves by these micro-breweries and estimate the implied welfare effects through the woodfuel market on private households as well as the environmental effect. We find substantial wood savings among the breweries, 36% to 38% if they fully switch to an improved stove. In absolute amounts, they save about 0.176 kg of fuelwood per litre of dolo brewed. These savings imply huge reductions in CO2-emissions and reduce the overall demand for woodfuel, which is predominantly used by the poorer strata for cooking purposes. We provide estimates for the price decrease that might result from this and show that the urban poor are likely to benefit. Thus, the intervention under study is an example for a green growth intervention with pro-poor welfare gains – something green growth strategies should look for. PMID:26244341

Introduction . Given its efficacy and safety, NexoBrid™ (NXB) has become part of our therapeutic options in burns treatment with satisfactory results. However, no cost analysis comparing NXB to the standard of care (SOC) has been carried out as of today. Aim . To assess the cost of treatment with NXB and compare it to the SOC cost. Methods . 20 patients with 14-22% of TBSA with an intermediate-deep thermal burn related injury were retrospectively and consecutively included. 10 of these patients were treated with the SOC, while the other 10 with NXB. The cost analysis was performed in accordance with the weighted average Italian Health Ministry DRGs and with Conferenza Stato/Regioni 2003 and the study by Tan et al. For each cost, 95% confidence intervals have been evaluated. Results . Considering the 10 patients treated with NXB, the overall savings (total net saving) amounted to 53300 euros. The confidence interval analysis confirmed the savings. Discussion . As shown by our preliminary results, significant savings are obtained with the use of NXB. The limit of our study is that it is based on Italian health care costs and assesses a relative small cohort of patients. Further studies on larger multinational cohorts are warranted.

This paper presents estimates of the key impacts of Federal energy and water conservation standards adopted from 1987 through 2013. The standards for consumer products and commercial and industrial equipment include those set by legislation as well as standards adopted by DOE through rulemaking. In 2013, the standards saved an estimated 4.05 quads of primary energy, which is equivalent to 4% of total U.S. energy consumption. The savings in operating costs for households and businesses totaledmore » $56 billion. The average household saved $$361 in operating costs as a result of residential and plumbing product standards. The estimated reduction in CO{sub 2} emissions associated with the standards in 2013 was 218 million metric tons, which is equivalent to 4% of total U.S. CO{sub 2} emissions. The estimated cumulative energy savings over the period 1990-2090 amount to 181 quads. Accounting for the increased upfront costs of more-efficient products and the operating cost (energy and water) savings over the products’ lifetime, the standards have a past and projected cumulative net present value (NPV) of consumer benefit of between $$1,271 billion and $1,487 billion, using 7 percent and 3 percent discount rates, respectively. The water conservation standards, together with energy conservation standards that also save water, reduced water use by 1.9 trillion gallons in 2013, and will achieve cumulative water savings by 2090 of 55 trillion gallons.

2013-12-01

Medicaid sterilization policy, which includes a mandatory 30-day waiting period between consent and the sterilization procedure, poses significant logistical barriers for many women who desire publicly funded sterilization. Our goal was to estimate the number of unintended pregnancies and the associated costs resulting from unfulfilled sterilization requests due to Medicaid policy barriers. We constructed a cost-effectiveness model from the health care payer perspective to determine the incremental cost over a 1-year time horizon of the current Medicaid sterilization policy compared to a hypothetical, revised policy in which women who desire a postpartum sterilization would face significantly reduced barriers. Probability estimates for potential outcomes in the model were based on published sources; costs of Medicaid-funded sterilizations and Medicaid-covered births were based on data from the Medicaid Statistical Information System and The Guttmacher Institute, respectively. With the implementation of a revised Medicaid sterilization policy, we estimated that the number of fulfilled sterilization requests would increase by 45%, from 53.3% of all women having their sterilization requests fulfilled to 77.5%. Annually, this increase could potentially lead to over 29,000 unintended pregnancies averted and $215 million saved. A revised Medicaid sterilization policy could potentially honor women's reproductive decisions, reduce the number of unintended pregnancies and save a significant amount of public funds. Compared to the current federal Medicaid sterilization policy, a hypothetical, revised policy that reduces logistical barriers for women who desire publicly funded, postpartum sterilization could potentially avert over 29,000 unintended pregnancies annually and therefore lead to cost savings of $215 million each year. © 2013.

Oral health promotion: the economic benefits to the NHS of increased use of sugarfree gum in the UK.

Claxton, L; Taylor, M; Kay, E

2016-02-12

The effect of sugarfree gum (SFG) on the prevention of dental caries has been established for some time. With increased constraints placed on healthcare budgets, the importance of economic considerations in decision-making about oral health interventions has increased. The aim of this study was to demonstrate the potential cost savings in dental care associated with increased levels of SFG usage. The analysis examined the amount of money which would hypothetically be saved if the UK 12-year-old population chewed more SFG. The number of sticks chewed per year and the caries risk reduction were modelled to create a dose response curve. The costs of tooth restoration, tooth extraction in primary care settings and under general anaesthetic were considered, and the effects of caries reduction on these costs calculated. If all members of the UK 12-year-old population chewed SFG frequently (twice a day), the potential cost savings for the cohort over the course of one year were estimated to range from £1.2 to £3.3 million and if they chewed three times a day, £8.2 million could be saved each year. Sensitivity analyses of the key parameters demonstrated that cost savings would still be likely to be observed even in scenarios with less significant increases in SFG use. This study shows that if levels of SFG usage in the teenage population in the UK could be increased, substantial cost savings might be achieved.

Estimating customer electricity savings from projects installed by the U.S. ESCO industry

DOE Office of Scientific and Technical Information (OSTI.GOV)

Carvallo, Juan Pablo; Larsen, Peter H.; Goldman, Charles A.

The U.S. energy service company (ESCO) industry has a well-established track record of delivering substantial energy and dollar savings in the public and institutional facilities sector, typically through the use of energy savings performance contracts (ESPC) (Larsen et al. 2012; Goldman et al. 2005; Hopper et al. 2005, Stuart et al. 2013). This ~$6.4 billion industry, which is expected to grow significantly over the next five years, may play an important role in achieving demand-side energy efficiency under local/state/federal environmental policy goals. To date, there has been little or no research in the public domain to estimate electricity savings formore » the entire U.S. ESCO industry. Estimating these savings levels is a foundational step in order to determine total avoided greenhouse gas (GHG) emissions from demand-side energy efficiency measures installed by U.S. ESCOs. We introduce a method to estimate the total amount of electricity saved by projects implemented by the U.S. ESCO industry using the Lawrence Berkeley National Laboratory (LBNL) /National Association of Energy Service Companies (NAESCO) database of projects and LBNL’s biennial industry survey. We report two metrics: incremental electricity savings and savings from ESCO projects that are active in a given year (e.g., 2012). Overall, we estimate that in 2012 active U.S. ESCO industry projects generated about 34 TWh of electricity savings—15 TWh of these electricity savings were for MUSH market customers who did not rely on utility customer-funded energy efficiency programs (see Figure 1). This analysis shows that almost two-thirds of 2012 electricity savings in municipal, local and state government facilities, universities/colleges, K-12 schools, and healthcare facilities (i.e., the so-called “MUSH” market) were not supported by a utility customer-funded energy efficiency program.« less

Effect of Different Ceramic Crown Preparations on Tooth Structure Loss: An In Vitro Study

NASA Astrophysics Data System (ADS)

Ebrahimpour, Ashkan

Objective: To quantify and compare the amount of tooth-structure reduction following the full-coverage preparations for crown materials of porcelain-fused-to-metal, lithium disilicate glass-ceramic and yttria-stabilized tetragonal zirconia polycrystalline for three tooth morphologies. Methods: Groups of resin teeth of different morphologies were individually weighed to high precision, then prepared following the preparation guidelines. The teeth were re-weighed after preparation and the amount of structural reduction was calculated. Statistical analyses were performed to find out if there was a significant difference among the groups. Results: Amount of tooth reduction for zirconia crown preparations was the lowest and statistically different compared with the other two materials. No statistical significance was found between the amount of reduction for porcelain-fused-to-metal and lithium disilicate glass-ceramic crowns. Conclusion: Within the limitations of this study, more tooth structure can be saved when utilizing zirconia full-coverage restorations compared with lithium disilicate glass-ceramic and porcelain-fused-to-metal crowns in maxillary central incisors, first premolars and first molars.

Monitoring Churn in Wireless Networks

NASA Astrophysics Data System (ADS)

Holzer, Stephan; Pignolet, Yvonne Anne; Smula, Jasmin; Wattenhofer, Roger

Wireless networks often experience a significant amount of churn, the arrival and departure of nodes. In this paper we propose a distributed algorithm for single-hop networks that detects churn and is resilient to a worst-case adversary. The nodes of the network are notified about changes quickly, in asymptotically optimal time up to an additive logarithmic overhead. We establish a trade-off between saving energy and minimizing the delay until notification for single- and multi-channel networks.

Energy management system saves $250,000 + fuel -with 4-mo payback

Massey, C.L.; Robe, K.

1980-09-01

Innovations made at Hershey Chocolate Company's Oakdale, California plant eliminated simultaneous cool-reheat-cycles by incorporating dead band controls into existing HVAC systems. Calculated savings of the project are about 90% of former heating and cooling energy usage for HVAC operation. Electric power savings amount to about $75,000/y, and natural gas savings about $185,000/y, using 1980 fuel costs, with an approximate 4-month payback. Because of the reduced demand for chilled water, a smaller water chiller carries full plant load for 4 to 5 months of the year without operating two existing 500-ton units.

Assessment of the greenhouse effect impact of technologies used for energy recovery from municipal waste: a case for England.

PubMed

Papageorgiou, A; Barton, J R; Karagiannidis, A

2009-07-01

Waste management activities contribute to global greenhouse gas emissions approximately by 4%. In particular the disposal of waste in landfills generates methane that has high global warming potential. Effective mitigation of greenhouse gas emissions is important and could provide environmental benefits and sustainable development, as well as reduce adverse impacts on public health. The European and UK waste policy force sustainable waste management and especially diversion from landfill, through reduction, reuse, recycling and composting, and recovery of value from waste. Energy from waste is a waste management option that could provide diversion from landfill and at the same time save a significant amount of greenhouse gas emissions, since it recovers energy from waste which usually replaces an equivalent amount of energy generated from fossil fuels. Energy from waste is a wide definition and includes technologies such as incineration of waste with energy recovery, or combustion of waste-derived fuels for energy production or advanced thermal treatment of waste with technologies such as gasification and pyrolysis, with energy recovery. The present study assessed the greenhouse gas emission impacts of three technologies that could be used for the treatment of Municipal Solid Waste in order to recover energy from it. These technologies are Mass Burn Incineration with energy recovery, Mechanical Biological Treatment via bio-drying and Mechanical Heat Treatment, which is a relatively new and uninvestigated method, compared to the other two. Mechanical Biological Treatment and Mechanical Heat Treatment can turn Municipal Solid Waste into Solid Recovered Fuel that could be combusted for energy production or replace other fuels in various industrial processes. The analysis showed that performance of these two technologies depends strongly on the final use of the produced fuel and they could produce GHG emissions savings only when there is end market for the fuel. On the other hand Mass Burn Incineration generates greenhouse gas emission savings when it recovers electricity and heat. Moreover the study found that the expected increase on the amount of Municipal Solid Waste treated for energy recovery in England by 2020 could save greenhouse gas emission, if certain Energy from Waste technologies would be applied, under certain conditions.

Energy 101: Energy Efficient Data Centers

ScienceCinema

2018-04-16

Data centers provide mission-critical computing functions vital to the daily operation of top U.S. economic, scientific, and technological organizations. These data centers consume large amounts of energy to run and maintain their computer systems, servers, and associated high-performance components—up to 3% of all U.S. electricity powers data centers. And as more information comes online, data centers will consume even more energy. Data centers can become more energy efficient by incorporating features like power-saving "stand-by" modes, energy monitoring software, and efficient cooling systems instead of energy-intensive air conditioners. These and other efficiency improvements to data centers can produce significant energy savings, reduce the load on the electric grid, and help protect the nation by increasing the reliability of critical computer operations.

2018-06-20

The benefits of digital pathology for workflow improvement and thereby cost savings in pathology, at least partly outweighing investment costs, are increasingly recognized. Successful implementations in a variety of scenarios start to demonstrate cost benefits of digital pathology for both research and routine diagnostics, contributing to a sound business case encouraging further adoption. To further support new adopters, there is still a need for detailed assessment of the impact this technology has on the relevant pathology workflows with emphasis on time saving. To assess the impact of digital pathology adoption on logistic laboratory tasks (i.e. not including pathologists' time for diagnosis making) in LabPON, a large regional pathology laboratory in The Netherlands. To quantify the benefits of digitization we analyzed the differences between the traditional analog and new digital workflows, carried out detailed measurements of all relevant steps in key analog and digital processes, and compared time spent. We modeled and assessed the logistic savings in five workflows: (1) Routine diagnosis, (2) Multi-disciplinary meeting, (3) External revision requests, (4) Extra stainings and (5) External consultation. On average over 19 working hours were saved on a typical day by working digitally, with the highest savings in routine diagnosis and multi-disciplinary meeting workflows. By working digitally, a significant amount of time could be saved in a large regional pathology lab with a typical case mix. We also present the data in each workflow per task and concrete logistic steps to allow extrapolation to the context and case mix of other laboratories. This article is protected by copyright.

DETERMINING THOSE "AT RISK" OF INSUFFICIENT RETIREMENT INCOME: The analysis in this paper was designed to answer two questions: 1) What percentage of U.S. households became "at risk" of insufficient retirement income as a result of the financial market and real estate crisis in 2008 and 2009? 2) Of those who are at risk, what additional savings do they need to make each year until retirement age to make up for their losses from the crisis? The results are from the 2010 EBRI Retirement Security Projection Model by the Employee Benefit Research Institute. Range at risk: The percentage of households that would not have been "at risk" without the 2008-2009 crisis but that ended up "at risk" varies from a low of 3.8 percent to a high of 14.3 percent. 50-50 chance of adequacy: Looking at all Early Boomer households that would need to save an additional amount (over and above the savings already factored into the baseline model), the median percentage of additional compensation for these households desiring a 50 percent probability of retirement income adequacy would be 3.0 percent of compensation each year until retirement age to account for the financial and housing market crisis in 2008 and 2009. 90 percent chance of adequacy: Looking at all Early Boomer households that would need to save an additional amount (over and above the savings already factored into the baseline model), the median percentage of additional compensation for these households desiring a 90 percent probability of retirement income adequacy would be 4.3 percent of compensation. Range of adequacy: Looking only at Early Boomer households that would need to save an additional amount (over and above the savings already factored into the baseline model), that had account balances in defined contribution plans and IRAs as well as exposure to the real estate crisis in 2008 and 2009 shows a median percentage for of 5.6 percent for a 50 percent probability and 6.7 percent for a 90 percent probability of retirement income adequacy.

Calibrated energy simulations of potential energy savings in actual retail buildings

NASA Astrophysics Data System (ADS)

Alhafi, Zuhaira

Retail stores are commercial buildings with high energy consumption due to their typically large volumes and long hours of operation. This dissertation assesses heating, ventilating and air conditioning saving strategies based on energy simulations with input parameters from actual retail buildings. The dissertation hypothesis is that "Retail store buildings will save a significant amount of energy by (1) modifying ventilation rates, and/or (2) resetting set point temperatures. These strategies have shown to be beneficial in previous studies. As presented in the literature review, potential energy savings ranged from 0.5% to 30% without compromising indoor thermal comfort and indoor air quality. The retail store buildings can be ventilated at rates significantly lower than rates called for in the ASHRAE Standard 62.1-2010 while maintaining acceptable indoor air quality. Therefore, two dissertation objectives are addressed: (1) Investigate opportunities to reduce ventilation rates that do not compromise indoor air quality in retail stores located in Central Pennsylvania, (2) Investigate opportunities to increase (in summer) and decrease (in winter) set point temperatures that do not compromise thermal comfort. This study conducted experimental measurements of ventilation rates required to maintain acceptable air quality and indoor environmental conditions requirements for two retail stores using ASHRAE Standard 62.1_2012. More specifically, among other parameters, occupancy density, indoor and outdoor pollutant concentrations, and indoor temperatures were measured continuously for one week interval. One of these retail stores were tested four times for a yearlong time period. Pollutants monitored were formaldehyde, carbon dioxide, particle size distributions and concentrations, as well as total volatile organic compounds. As a part of the base protocol, the number of occupants in each store was hourly counted during the test, and the results reveal that the occupant densities were approximately 20% to 30% of that called by ASHRAE 62.1. Formaldehyde was the most important contaminant of concern in retail stores investigated. Both stores exceeded the most conservative health guideline for formaldehyde (OEHHA TWA REL = 7.3 ppb). This study found that source removal and reducing the emission rate, as demonstrated in retail stores sampled in this study, is a viable strategy to meet the health guideline. Total volatile compound were present in retail stores at low concentrations well below health guidelines suggested by Molhave (1700microg /m 2) and Bridges (1000 microg /m2). Based on these results and through mass--balance modeling, different ventilation rate reduction scenarios were proposed, and for these scenarios the differences in energy consumption were estimated. Findings of all phases of this desertion have contributed to understanding (a) the trade-off between energy savings and ventilation rates that do not compromise indoor air quality, and (b) the trade-off between energy savings and resets of indoor air temperature that do not compromise thermal comfort. Two models for retail stores were built and calibrated and validated against actual utility bills. Energy simulation results indicated that by lowering the ventilation rates from measured and minimum references would reduce natural gas energy use by estimated values of 6% to 19%. Also, this study found that the electrical cooling energy consumption was not significantly sensitive to different ventilation rates. However, increasing indoor air temperature by 3°C in summer had a significant effect on the energy savings. In winter, both energy savings strategies, ventilation reduction and decrease in set points, had a significant effect on natural gas consumption. Specially, when the indoor air temperature 21°C was decreased to 19.4°C with the same amount of ventilation rate of Molhaves guideline for both cases. Interestingly, the temperature of 23.8°C (75°F), which is the lowest value of ASHRAE 55 thermal comfort for sedentary people (cashiers) and the highest value for thermal comfort adjustments due to activity level (customers and workers) that are calculated by using empirical equation, was the optimum temperature for sedentary and active people in Retail store buildings.

Oral health promotion: the economic benefits to the NHS of increased use of sugarfree gum in the UK

PubMed Central

Claxton, L.; Taylor, M.; Kay, E.

2016-01-01

Introduction The effect of sugarfree gum (SFG) on the prevention of dental caries has been established for some time. With increased constraints placed on healthcare budgets, the importance of economic considerations in decision-making about oral health interventions has increased. The aim of this study was to demonstrate the potential cost savings in dental care associated with increased levels of SFG usage. Methods The analysis examined the amount of money which would hypothetically be saved if the UK 12-year-old population chewed more SFG. The number of sticks chewed per year and the caries risk reduction were modelled to create a dose response curve. The costs of tooth restoration, tooth extraction in primary care settings and under general anaesthetic were considered, and the effects of caries reduction on these costs calculated. Results If all members of the UK 12-year-old population chewed SFG frequently (twice a day), the potential cost savings for the cohort over the course of one year were estimated to range from £1.2 to £3.3 million and if they chewed three times a day, £8.2 million could be saved each year. Sensitivity analyses of the key parameters demonstrated that cost savings would still be likely to be observed even in scenarios with less significant increases in SFG use. Conclusion This study shows that if levels of SFG usage in the teenage population in the UK could be increased, substantial cost savings might be achieved. PMID:26868801

Operating room waste reduction in plastic and hand surgery.

PubMed

Albert, Mark G; Rothkopf, Douglas M

2015-01-01

Operating rooms (ORs), combined with labour and delivery suites, account for approximately 70% of hospital waste. Previous studies have reported that recycling can have a considerable financial impact on a hospital-wide basis; however, its importance in the OR has not been demonstrated. To propose a method of decreasing cost through judicious selection of instruments and supplies, and initiation of recycling in plastic and hand surgery. The authors identified disposable supplies and instruments that are routinely opened and wasted in common plastic and hand surgery procedures, and calculated the savings that can result from eliminating extraneous items. A cost analysis was performed, which compared the expense of OR waste versus single-stream recycling and the benefit of recycling HIPAA documents and blue wrap. Fifteen total items were removed from disposable plastic packs and seven total items from hand packs. A total of US$17,381.05 could be saved per year from these changes alone. Since initiating single-stream recycling, the authors' institution has saved, on average, US$3,487 per month at the three campuses. After extrapolating at the current savings rate, one would expect to save a minimum of US$41,844 per year. OR waste reduction is an effective method of decreasing cost in the surgical setting. By revising the contents of current disposable packs and instrument sets designated for plastic and hand surgery, hospitals can reduce the amount of opened and unused material. Significant financial savings and environmental benefit can result from this judicious supply and instrument selection, as well as implementation of recycling.

Potential unintended pregnancies averted and cost savings associated with a revised Medicaid sterilization policy

2013-01-01

Objective Medicaid sterilization policy, which includes a mandatory 30-day waiting period between consent and the sterilization procedure, poses significant logistical barriers for many women who desire publicly-funded sterilization. Our goal was to estimate the number of unintended pregnancies and the associated costs resulting from unfulfilled sterilization requests due to Medicaid policy barriers. Study design We constructed a cost effectiveness model from the health care payer perspective to determine the incremental cost over a 1-year time horizon of the current Medicaid sterilization policy compared to a hypothetical, revised policy in which women who desire a post-partum sterilization would face significantly reduced barriers. Probability estimates for potential outcomes in the model were based on published sources; costs of Medicaid-funded sterilizations and Medicaid-covered births were based on data from the Medicaid Statistical Information System and The Guttmacher Institute, respectively. Results With the implementation of a revised Medicaid sterilization policy, we estimated that the number of fulfilled sterilization requests would increase by 45%, from 53.3% of all women having their sterilization requests fulfilled to 77.5%. Annually, this increase could potentially lead to over 29,000 unintended pregnancies averted and $215 million saved. Conclusion A revised Medicaid sterilization policy could potentially honor women's reproductive decisions, reduce the number of unintended pregnancies, and save a significant amount of public funds. Implication Compared to the current federal Medicaid sterilization policy, a hypothetical, revised policy that reduces logistical barriers for women who desire publicly-funded, post-partum sterilization could potentially avert over 29,000 unintended pregnancies annually and therefore lead to a cost savings of $215 million each year.

Introduction. Given its efficacy and safety, NexoBrid™ (NXB) has become part of our therapeutic options in burns treatment with satisfactory results. However, no cost analysis comparing NXB to the standard of care (SOC) has been carried out as of today. Aim. To assess the cost of treatment with NXB and compare it to the SOC cost. Methods. 20 patients with 14–22% of TBSA with an intermediate-deep thermal burn related injury were retrospectively and consecutively included. 10 of these patients were treated with the SOC, while the other 10 with NXB. The cost analysis was performed in accordance with the weighted average Italian Health Ministry DRGs and with Conferenza Stato/Regioni 2003 and the study by Tan et al. For each cost, 95% confidence intervals have been evaluated. Results. Considering the 10 patients treated with NXB, the overall savings (total net saving) amounted to 53300 euros. The confidence interval analysis confirmed the savings. Discussion. As shown by our preliminary results, significant savings are obtained with the use of NXB. The limit of our study is that it is based on Italian health care costs and assesses a relative small cohort of patients. Further studies on larger multinational cohorts are warranted. PMID:28293640

The purpose of this study was to evaluate the economic effects of repackaging disposable laparoscopic surgical instruments. We repacked a total of 28 disposable instruments for gynecologic laparoscopic surgery into one package. The time of preparation of surgical instruments, the amount of medical waste, and other economic effects were compared before and after the repackaging of disposable instruments. The time required for the preparation of surgical instruments was shortened by 22 minutes per operation, and medical waste decreased by 400 g, by repackaging the instruments, resulting in an estimated direct economic saving of $10,000 per year. Indirect economic effects might include savings due to a reduced inventory of surgical instruments and simplified cost-accounting for each operation. It is likely that preparation for surgery can be significantly improved and the cost reduced by repackaging the laparoscopic surgical instruments.

Previous work has shown that wallboard can be successfully manufactured to contain up to 30% phase-change material (PCM), or wax, thus enabling this common building material to serve as a thermal energy storage device. The PCM wallboard was analyzed for passive solar applications and found to save energy with a reasonable payback time period of five years. Further evaluations of the wallboard are reported in this paper. This analysis looks at potential applications of PCM wallboard as a load management device and as a comfort enhancer. Results show that the wallboard is ineffective in modifying the comfort level but canmore » provide significant load management relief. In some applications the load management strategy also serves to save a small amount of energy, in others there is a small energy penalty.« less

Cost-benefit analysis of Xpert MTB/RIF for tuberculosis suspects in German hospitals.

Diel, Roland; Nienhaus, Albert; Hillemann, Doris; Richter, Elvira

2016-02-01

Our objective was to assess the cost-benefit of enhancing or replacing the conventional sputum smear with the real-time PCR Xpert MTB/RIF method in the inpatient diagnostic schema for tuberculosis (TB).Recent data from published per-case cost studies for TB/multidrug-resistant (MDR)-TB and from comparative analyses of sputum microscopy, mycobacterial culture, Xpert MTB/RIF and drug susceptibility testing, performed at the German National Reference Center for Mycobacteria, were used. Potential cost savings of Xpert MTB/RIF, based on test accuracy and multiple cost drivers, were calculated for diagnosing TB/MDR-TB suspects from the hospital perspective.Implementing Xpert MTB/RIF as an add-on in smear-positive and smear-negative TB suspects saves on average €48.72 and €503, respectively, per admitted patient as compared with the conventional approach. In smear-positive and smear-negative MDR-TB suspects, cost savings amount to €189.56 and €515.25 per person, respectively. Full replacement of microscopy by Xpert MTB/RIF saves €449.98. In probabilistic Monte-Carlo simulation, adding Xpert MTB/RIF is less costly in 46.4% and 76.2% of smear-positive TB and MDR-TB suspects, respectively, but 100% less expensive in all smear-negative suspects. Full replacement by Xpert MTB/RIF is also consistently cost-saving.Using Xpert MTB/RIF as an add-on to and even as a replacement for sputum smear examination may significantly reduce expenditures in TB suspects.

This study examines participants' savings in children's savings accounts (CSAs) set up for AIDS-orphaned children ages 10-15 in Uganda. Using a cluster randomized experimental design, we examine the extent to which families participating in a CSA program report more savings than their counterparts not participating in the program, explore the extent to which families who participate in the CSA program report using formal financial institutions compared with families who do not have a CSA, and consider whether families participating in the CSA program bring new money into the CSA or whether they reshuffle existing household assets. We find that participating in a CSA increased families' likelihood to report having saved money. However, our results show no intervention effect either on the amount of self-reported savings or on the likelihood of using formal financial institutions. Further research is needed to understand whether use of a CSA helps families generate new wealth.

A method is described for estimating a building's energy savings attributed to daylighting by predicting the percentage of the year that the electric lighting system is not in use. This depends on the particular control strategy chosen, a standard work year, and the amount of light (as a daylight factor) reaching on daylight and sunlight availability for selected cities in the United States.

Lean principles have been used at Denver Health Medical Center since 2005 to streamline nonclinical processes. Despite allocation of significant resources, particularly the expense of low molecular weight heparin (LMWH), to prophylaxis of venous thromboembolism (VTE), the incidence of postoperative VTE was significantly worse than national benchmarks. VTE risk factors were not consistently assessed, and the prescribing of prophylaxis varied widely. Lean was employed to standardize and implement risk assessment and evidence-based VTE prophylaxis for the institution. In a rapid improvement event, a multidisciplinary group formulated an evidence-based risk assessment tool and clinical practice guideline for VTE prophylaxis, with plans for hospitalwide implementation and monitoring. The effects were immediate and improved steadily with feedback to clinicians. Within six months, compliance with the standard approached 100%. One year after implementation, the use of LMWH decreased more than 60% below baseline, and the use of sequential compression devices decreased by nearly 30%. With increased use of unfractionated heparin, the cost savings on VTE prophylaxis exceeded $15,000 per month, for a total of $425,000 since implementation. Moreover, the incidence of VTE decreased markedly during the same period. By reducing VTE rates, a total cost savings of $6.2 million was estimated for the past 28 months. Applying Lean to the clinical management of VTE prophylaxis improved compliance with standards and saved the hospital a significant amount of money. This was achieved without compromising clinical outcomes. This experience could be replicated at other institutions.

1984-01-01

The results of a comprehensive analysis of near term electric hybrid vehicles are presented, with emphasis on their potential to save significant amounts of petroleum on a national scale in the 1990s. Performance requirements and expected annual usage patterns of these vehicles are first modeled. The projected U.S. fleet composition is estimated, and conceptual hybrid vehicle designs are conceived and analyzed for petroleum use when driven in the expected annual patterns. These petroleum consumption estimates are then compared to similar estimates for projected 1990 conventional vehicles having the same performance and driven in the same patterns. Results are presented in the form of three utility functions and comparisons of sevral conceptual designs are made. The Hybrid Vehicle (HV) design and assessment techniques are discussed and a general method is explained for selecting the optimum energy management strategy for any vehicle mission battery combination. Conclusions and recommendations are presented, and development recommendations are identified.

2014-05-01

Jatropha curcas is the most promising energy tree, and soil moisture is the key factor which affects the seedling quality and water use efficiency of J. curcas. With aims to evaluate the effect of different irrigation amount on growth, morphological characteristics and water use of J. curcas, a pot experiment was conducted with four irrigation amounts, i. e., W1:472.49 mm, W2: 228.79 mm, W3:154.18 mm and W4:106.93 mm, respectively. Compared with W1 treatment, the leaf area and stem cross-section area of base significantly decreased in W2, W3 and W4 treatments, but Huber value significantly increased, which could improve the efficiency of water transfer from root to shoot, thus enhance the capability of resistance to drought stress. Compared with W, treatment, the healthy index of J. curcas seedlings decreased slightly in W2 treatment but significantly decreased in W3 and W4 treatments. Hence, the irrigation amount from 228.79 to 472.49 mm was beneficial to increase the healthy index of J. curcas seedlings. Compared with W1 treatment, irrigation water was saved by 67.4% in W3 treatment, and the total dry mass and evapotranspiration significantly decreased by 17.4% and 68.6%, and the irrigation water use efficiency and total water use efficiency increased by 153.2% and 163.2%, respectively. In the condition of this study, the irrigation amount of 154.18 mm was beneficial to increase water use efficiency.

A review on waste heat recovery from exhaust in the ceramics industry

Delpech, Bertrand; Axcell, Brian; Jouhara, Hussam

2017-11-01

Following the energy crisis in 1980, many saving technologies have been investigated with attempts to implement them into various industries, one of them is the field of ceramic production. In order to comply with energy saving trends and environmental issues, the European ceramic industry sector has developed energy efficient systems which reduced significantly production time and costs and reduced total energy consumption. The last achievement is of great importance as the energy consumption of the ceramic process accounts for a significant percentage of the total production costs. More precisely, the firing stage consumes the highest amount of energy during the whole ceramic production process. The use of roller kilns, fired by natural gas, involves a loss of 50% of the input energy via the flue gas and the cooling gas exhausts. This review paper briefly describes the production process of the different ceramic products, with a focus on the ceramic sector in Europe. Due to the limited on waste heat recovery in the ceramic industry, other high temperature waste heat recovery applications are considered in the paper, such as in concrete and steel production, which could have a potential use in the ceramic industry. The state of the art technologies used in the ceramics industry are reviewed with a special interest in waste heat recovery from the ceramic process exhaust stacks and energy saving technologies.

1982-01-01

Research on natural laminar flow, laminar flow control by suction, and turbulent drag reduction is discussed. Preliminary results suggest that a significant amount of natural laminar flow can be achieved on small, straight wing airplanes. On larger, swept wing aircraft, laminar flow control by distributed suction is expected to result in significant fuel savings. The area over which laminar flow control is applied depends on tradeoffs involving structural complexity, maintenance, and cost. Several methods of reducing turbulent skin friction by altering the turbulence structure itself have shown promise in exploratory testing. The status of these technologies and the benefits of applying them to future aircraft are reviewed.

Accrued Cost Savings of a Free Clinic Using Quality-Adjusted Life Years Saved and Return on Investment.

PubMed

Sanders, Jim; Lacey, Marcus; Guse, Clare E

2017-01-01

Savings garnered through the provision of preventive services is a form of profit for health systems. Free clinics have been using this logic to demonstrate their cost-savings. The Community-Based Chronic Disease Management (CCDM) clinic treats hypertension using nurse-led teams, clinical protocols, and community-based settings. We calculated CCDM's cost-effectiveness from 2007 to 2013 using 2 metrics: Quality-adjusted life years (QALYs) saved and return on investment (ROI). QALYs were calculated using the Clinical Preventive Burden (CPB) score for hypertension care. ROI was calculated by tallying the savings from prevented heart attacks, strokes, and emergency department visits against the total operating costs. Using conservative assumptions for cost estimates, hypertension care resulted in a value of QALYs saved of $711,000 to $2,133,000 and an ROI ratio range of 0.35 to 1.20. Our study shows that when using conservative assumptions to calculate cost-savings, our free clinic did not save money. Cost-savings did occur, but the amount was modest, was less than that of cost-inputs, and was not likely captured by any single health entity. Although free clinics remain a vital health care access point for many Americans, it has yet to be demonstrated that they generate a net savings. © Copyright 2017 by the American Board of Family Medicine.

[Environmental safety assessment on the new super absorbent polymers applied into a soil-Chinese cabbage system].

Li, Xi; He, Ji-Zheng; Zheng, Yuan-Ming; Zheng, Ming-Lan

2014-02-01

Super absorbent polymers (SAPs), a new water retention material, have a potential for application in water-saving agricultural production. In this study, we investigated the effects of SAPs, synthesized from natural plant extracts, on Chinese cabbage fresh weight, soil water content, soil water stable aggregates, soil microbial biomass (carbon) and soil microbial respiration under three water conditions (excessive, normal and deficient) and two SAPs application strategies (bulk treatment and spraying treatment). The results showed that the SAPs significantly promoted the soil water content, water-stable aggregates (> 0.25 mm) and the soil microbial activities, especially under the water deficient conditions. Meanwhile, SAP application strategy was of great significance to the effects on Chinese cabbage and soil properties. Compared with the control treatment under normal water condition, spraying treatment of Jaguar C (S-JC) could reduce irrigation water amount by about 25% without reducing the crop production. Furthermore, compared with the control treatment under the same water condition with S-JC (deficient), it could increase Chinese cabbage production by 287%. Thus, SAPs is an environmental friendly water-saving technique in agricultural production.

2004-01-01

This study was designed to evaluate the effects of an employee influenza vaccination campaign, measured in terms of health and economic benefits. Colombian bank employees volunteered to take part in this prospective observational study involving two groups: vaccinated and nonvaccinated. Socioeconomic and health status information, including influenza-like symptoms, sick leave, and postvaccination adverse events, were collected via questionnaires. Cost-benefit analyses were performed to determine whether the employer would save money overall by paying for the vaccination program. Between October 2000 and May 2001, 424 vaccinated subjects and 335 nonvaccinated subjects volunteered to join the study. Cumulative incidence of influenza-like illness (ILI) was lower among vaccinated (14.6%) than nonvaccinated subjects (39.4%). Fever was the most common ILI symptom (93% of all reported ILI). Absence rates because of ILI were similar in the two groups (2.59%-2.69%). Assuming that employees with ILI who continue to work have reduced effectiveness (30%-70% of normal) the employer can save 6.4 US dollars to 25.8 US dollars per vaccinated employee based on labor costs alone. This saving increases to 89.3 US dollars to 237.8 US dollars when operating income is also considered. Sensitivity analyses indicate that the vaccination program will be cost saving for vaccination coverage above 20% and ILI rates above 10%. Among the studied volunteers, ILI has significant impact on work productivity in terms of indirect costs. Implementing an influenza vaccination program would reduce the burden of ILI and save substantial amounts of money for the company.

Multidose Botulinum Toxin A for Intralaryngeal Injection: A Cost Analysis.

PubMed

Gilbert, Mark R; Young, VyVy N; Smith, Libby J; Rosen, Clark A

2018-01-04

Botulinum toxin A (BtxA) injection is the mainstay treatment for laryngeal dystonias. BtxA product labeling states that reconstituted toxin should be used within 4 hours on a single patient despite several studies that have demonstrated multidose BtxA to be safe and effective. Many insurance carriers mandate the use of an outside pharmacy which necessitates a single-use approach. This study compares the cost savings of multidose BtxA for laryngeal dystonia compared to single-use. This is a retrospective review and projected cost savings analysis. Records and billing information were reviewed for patients receiving BtxA for intralaryngeal injection at a single laryngology division in 2015. Inclusion criteria included CPT 64617 or J0585; exclusion criteria included CPT 64616. The price of BtxA 100 unit vial for calculation was $670. A total of 142 patients were seen for intralaryngeal BtxA injection resulting in 337 visits over 1 year. The average BtxA dose per visit was 2.86 units with an average of 3.06 procedure visits per year. The calculated cost of BtxA treatment using a single vial approach was found to be $2,050 per patient per year. If billed instead for $7/unit with 5 units wastage charge per visit, the yearly per patient charge is $168. Single vial-use of BtxA injection thus represents a 1,118% price increase versus multidose use. When estimated for yearly prevalence of spasmodic dysphonia, multidose BtxA use would save almost $100 million annually. Multidose botulinum toxin A application utilizing per unit billing is significantly less expensive than per single-use vial billing and would save the health-care system significant amount of money without any sacrifice in safety or effectiveness.

Performance of a large building rainwater harvesting system.

Ward, S; Memon, F A; Butler, D

2012-10-15

Rainwater harvesting is increasingly becoming an integral part of the sustainable water management toolkit. Despite a plethora of studies modelling the feasibility of the utilisation of rainwater harvesting (RWH) systems in particular contexts, there remains a significant gap in knowledge in relation to detailed empirical assessments of performance. Domestic systems have been investigated to a limited degree in the literature, including in the UK, but there are few recent longitudinal studies of larger non-domestic systems. Additionally, there are few studies comparing estimated and actual performance. This paper presents the results of a longitudinal empirical performance assessment of a non-domestic RWH system located in an office building in the UK. Furthermore, it compares actual performance with the estimated performance based on two methods recommended by the British Standards Institute - the Intermediate (simple calculations) and Detailed (simulation-based) Approaches. Results highlight that the average measured water saving efficiency (amount of mains water saved) of the office-based RWH system was 87% across an 8-month period, due to the system being over-sized for the actual occupancy level. Consequently, a similar level of performance could have been achieved using a smaller-sized tank. Estimated cost savings resulted in capital payback periods of 11 and 6 years for the actual over-sized tank and the smaller optimised tank, respectively. However, more detailed cost data on maintenance and operation is required to perform whole life cost analyses. These findings indicate that office-scale RWH systems potentially offer significant water and cost savings. They also emphasise the importance of monitoring data and that a transition to the use of Detailed Approaches (particularly in the UK) is required to (a) minimise over-sizing of storage tanks and (b) build confidence in RWH system performance.

Economical ground data delivery

NASA Technical Reports Server (NTRS)

Markley, Richard W.; Byrne, Russell H.; Bromberg, Daniel E.

1994-01-01

Data delivery in the Deep Space Network (DSN) involves transmission of a small amount of constant, high-priority traffic and a large amount of bursty, low priority data. The bursty traffic may be initially buffered and then metered back slowly as bandwidth becomes available. Today both types of data are transmitted over dedicated leased circuits. The authors investigated the potential of saving money by designing a hybrid communications architecture that uses leased circuits for high-priority network communications and dial-up circuits for low-priority traffic. Such an architecture may significantly reduce costs and provide an emergency backup. The architecture presented here may also be applied to any ground station-to-customer network within the range of a common carrier. The authors compare estimated costs for various scenarios and suggest security safeguards that should be considered.

Preventable drug waste among anesthesia providers: opportunities for efficiency.

2016-05-01

Health care service bundling experiments at the state and regional levels have showed reduced costs by providing a single lump-sum reimbursement for anesthesia services, surgery, and postoperative care. Potential for cost savings related to the provision of anesthesia care has the potential to significantly impact sustainability. This study defines and quantifies routine and preventable anesthetic drug waste and the patient, procedure, and anesthesia provider characteristics associated with increased waste. Over a 12-month period, the type and quantity of clean drugs prepared by the anesthesia team for the first case of the day were recorded. The amount of each drug administered was obtained from the computerized anesthesia record, and data were analyzed to determine the incidence and cost of routine and preventable drug waste. The monthly and yearly cost of preventable waste, including the cost of pharmacy tech labor and materials where applicable, was estimated based on surgical case volume at the study institution. All analyses were performed using SAS software v9.2. Anesthetic drugs prepared for 543 separate surgical cases were observed. Less than 20% of cases generated routine waste. Preventable waste was generated most frequently for ephedrine (59.5% of cases), succinylcholine (33.7%), and lidocaine (25.1%), and least frequently for ondansetron (1.3%), phenylephrine (2.6%), and dexamethasone (2.8%). The estimated yearly cost of preventable anesthetic drug waste was $185,250. Significant potential savings with little impact on clinically significant availability may be achieved through the use of prefilled syringes for some commonly used anesthetic drugs. An intelligently implemented switch to prefilled syringes for select drugs is a potential cost saving measure, but savings might be diminished by disposal of prefilled syringes when they expire, hidden costs in the hospital pharmacy, and inability to supply some medications in prefilled syringes due to stability or manufacturing issues.

Choosing the right amount of healthcare information technologies investments.

Meyer, Rodolphe; Degoulet, Patrice

2010-04-01

Choosing and justifying the right amount of investment in healthcare information technologies (HITECH or HIT) in hospitals is an ever increasing challenge. Our objectives are to assess the financial impact of HIT on hospital outcome, and propose decision-helping tools that could be used to rationalize the distribution of hospital finances. We used a production function and microeconomic tools on data of 21 Paris university hospitals recorded from 1998 to 2006 to compute the elasticity coefficients of HIT versus non-HIT capital and labor as regards to hospital financial outcome and optimize the distribution of investments according to the productivity associated with each input. HIT inputs and non-HIT inputs both have a positive and significant impact on hospital production (elasticity coefficients respectively of 0.106 and 0.893; R(2) of 0.92). We forecast 2006 results from the 1998 to 2005 dataset with an accuracy of +0.61%. With the model used, the best proportion of HIT investments was estimated to be 10.6% of total input and this was predicted to lead to a total saving of 388 million Euros for the 2006 dataset. Considering HIT investment from the point of view of a global portfolio and applying econometric and microeconomic tools allow the required confidence level to be attained for choosing the right amount of HIT investments. It could also allow hospitals using these tools to make substantial savings, and help them forecast their choices for the following year for better HITECH governance in the current stimulation context.

Plastics are making a growing contribution to sustainable development. For example, over an expected lifetime of 50 years, the use of window frames and insulating materials made of plastic in buildings save many times the energy required to manufacture them. Plastics for packaging purposes provide protection against damage and dirt contamination, thereby saving considerable amounts of material and energy. Choosing appropriate disposal strategies for plastic waste also helps to protect the environment (Mark 2000).

This study examines variations in saving behavior among poor families enrolled in a Child Savings Account program for orphaned and vulnerable school-going children in Uganda. We employ multilevel analyses using longitudinal data from a cluster-randomized experimental design. Our analyses reveal the following significant results: (1) given the average number of months during which the account was open (18 months), families saved on average, USD 54.72, which, after being matched by the program (2:1 match rate) comes to USD 164.16—enough to cover approximately five academic terms of post-primary education; (2) children's saving behavior was not associated with quality of family relations; it was, however, significantly associated with family financial socialization; (3) family demographics were significantly associated with children's saving behavior in the matched Child Savings Account program; and (4) children enrolled in some schools saved better compared to children enrolled in other schools within the same treatment group.

Eggli, S; Holm, J

2001-12-01

The increasing amount of clinical data, intensified interest of patients in medical information, medical quality management and the recent cost explosion in health care systems have forced medical institutions to improve their strategy in handling medical data. In the orthopedic department (3,600 surgeries, 75 beds, 14,000 consultations) software application for comprehensive patient data management has been developed. When implementing the electronic patient history following criteria were evaluated: 1. software evaluation, 2. implementation, 3. work flow, 4. data security/system stability. In the first phase the functional character was defined. Implementation required 3 months after parametrization. The expense amounted to 130,000 DM (30 clients). The training requirements were one afternoon for the secretaries and a 2-h session for the residents. The access speed on medically relevant data averaged under 3 s. The average saving in working hours was approximately 5 h/week for the secretaries and 4 h/week for the residents. The saving in paper amounted to 36,000 sheets/year. In 3 operational years there were 3 server breakdowns. Evaluation of the saving on working hours showed that such a system can amortize within a year. The latest improvements in hardware and software technology made the electronic medical record with integrated quality-control practicable without massive expenditure. The system supplies an extensive platform of information for patient treatment and an instrument to evaluate the efficiency of therapy strategies independent of the clinical field.

Quantifying Behavior Driven Energy Savings for Hotels

2016-08-12

Hotel facilities present abundant opportunities for energy savings. In the United States, there are around 25,000 hotels that spend on an average of $2,196 on energy costs per room each year. This amounts to about 6% of the total annual hotel operating cost. However, unlike offices, there are limited studies on establishing appropriate baselines and quantifying hotel energy savings given the variety of services and amenities, unpredictable customer behaviors, and the around-the-clock operation hours. In this study, we investigate behavior driven energy savings for three medium-size (around 90,000 sf2) hotels that offer similar services in different climate zones. We firstmore » used Department of Energy Asset Scoring Tool to establish baseline models. We then conducted energy saving analysis in EnergyPlus based on a behavior model that defines the upper bound and lower bound of customer and hotel staff behavior. Lastly, we presented a probabilistic energy savings outlook for each hotel. The analysis shows behavior driven energy savings up to 25%. We believe this is the first study to incorporate behavioral factors into energy analysis for hotels. It also demonstrates a procedure to quickly create tailored baselines and identify improvement opportunities for hotels.« less

Steam dispatching control system demonstration at Fort Benjamin Harrison. Final technical report

DOE Office of Scientific and Technical Information (OSTI.GOV)

Diks, C.L.; Moshage, R.E.; Lin, M.C.

1993-07-01

Currently most Army Central steam heating systems operate by maintaining a constant steam pressure regardless of actual steam demand. This method offers some operational convenience, but is often the cause of significant energy losses. Researchers at the U.S. Army Construction Engineering Research Laboratories (USACERL) have investigated the Steam Dispatching Control System (SDCS), a control system that lowers supply steam pressure-and therefore steam temperature-to slightly above the amount needed to meet the steam demand. The lower Steam temperature and reduction in steam loss (from leaks and faulty traps) result in lower heat losses and higher energy savings. Limiting steam pressure canmore » diminish the amount of excess heat loss in the distribution system while still meeting the demand. The Army's Facilities Engineering Applications Program (FEAP) chose Fort Benjamin Harrison, IN, as the Army demonstration site for SDCS. Researchers found that use of SDCS is technically and economically viable improvement over current operating procedures. Analysis based on demonstration results show that the simple payback for SDCS is less than 1 year. The results of this demonstration are generally applicable to installations with a large central heating plant and a substantial steam distribution system. Findings, indicate that energy savings form SDCS are significant regardless of what type of fuel powers the boiler. The authors note that, during the initial evaluation of a potential SDCS application, attention must be paid to the condensate return to ensure that it will operate properly.

Towards energy-efficient photonic interconnects

Demir, Yigit; Hardavellas, Nikos

2015-03-01

Silicon photonics have emerged as a promising solution to meet the growing demand for high-bandwidth, low-latency, and energy-efficient on-chip and off-chip communication in many-core processors. However, current silicon-photonic interconnect designs for many-core processors waste a significant amount of power because (a) lasers are always on, even during periods of interconnect inactivity, and (b) microring resonators employ heaters which consume a significant amount of power just to overcome thermal variations and maintain communication on the photonic links, especially in a 3D-stacked design. The problem of high laser power consumption is particularly important as lasers typically have very low energy efficiency, and photonic interconnects often remain underutilized both in scientific computing (compute-intensive execution phases underutilize the interconnect), and in server computing (servers in Google-scale datacenters have a typical utilization of less than 30%). We address the high laser power consumption by proposing EcoLaser+, which is a laser control scheme that saves energy by predicting the interconnect activity and opportunistically turning the on-chip laser off when possible, and also by scaling the width of the communication link based on a runtime prediction of the expected message length. Our laser control scheme can save up to 62 - 92% of the laser energy, and improve the energy efficiency of a manycore processor with negligible performance penalty. We address the high trimming (heating) power consumption of the microrings by proposing insulation methods that reduce the impact of localized heating induced by highly-active components on the 3D-stacked logic die.

2014-02-01

Patient assistance programs and the 340B Drug Pricing Program promise to improve the financial stability, better serve vulnerable patients, and decrease the burden of cost for uninsured patients. Our objective is to examine the financial impact that PAPs and the 340B Program have on improving medication cost. Retrospective analysis of medication dispensary data. Dispensary data for uninsured patients obtaining medications at 2 community health centers were collected from February 1 to February 29, 2012. Uninsured patients were divided into 2 samples: (1) patients receiving PAP medications and (2) patients receiving 340B medications. The main outcome measured was the patient's cost savings. Cost savings were calculated based on the amount a medication would have cost had it been purchased by patients at prices found on Epocrates software (drugstore.com). A paired sample t test model using continuous variables was utilized to calculate confidence intervals. A total of 1420 PAP and 2772 340B individual medications were dispensed to uninsured patients in February 2012. For patients receiving PAP medications the mean ± standard deviation (SD) for age = 52 ± 10. Average cost was $0.11 (95% CI, $0.04-$0.17) and average savings was $617.36 (95% Cl, $581.32-$653.40). For patients receiving 340B medications the mean ±SD for age = 50 ± 14. Average cost was $11.50 (95% CI, $10.55-$12.45). Average saving was $62.31 (95% CI, $57.99-$66.63). PAPs and 340B provide significant medication savings for uninsured patient. More research is needed to establish "best practices" for the successful integration of PAPs.

With the increasing concern over the energy expenditure due to rapid ICT expansion and growth of Internet traffic volume, there is a growing trend towards developing energy-efficient ICT solutions. Passive Optical Network (PON), which is regarded as a key enabler to facilitate high speed broadband connection to individual subscribers, is considered as one of the energy-efficient access network technologies. However, an immense amount of research effort can be noticed in academia and industries to make PON more energy-efficient. In this paper, we aim at improving energy saving performance of Time Division Multiplexing (TDM)-PON, which is the most widely deployed PON technology throughout the world. A commonly used approach to make TDM-PON energy-efficient is to use sleep mode in Optical Network Units (ONUs), which are the customer premises equipment of a TDM-PON system. However, there is a strong trade-off relationship between traffic delay performance of an ONU and its energy saving (the longer the sleep interval length of an ONU, the lower its energy consumption, but the higher the traffic delay, and vice versa). In this paper, we propose an Energy-efficient Uplink and Downlink Delay Aware (EUDDA) scheme for TDM-PON system. The prime object of EUDDA is to meet both downlink and uplink traffic delay requirement while maximizing energy saving performance of ONUs as much as possible. In EUDDA, traffic delay requirement is given more priority over energy saving. Even so, it still can improve energy saving of ONUs noticeably. We evaluate performance of EUDDA in front of two existing solutions in terms of traffic delay, jitter, and ONU energy consumption. The performance results show that EUDDA significantly outperforms the other existing solutions.

Conventional development versus managed growth: the costs of sprawl.

2003-09-01

We examined the effects of sprawl, or conventional development, versus managed (or "smart") growth on land and infrastructure consumption as well as on real estate development and public service costs in the United States. Mathematical impact models were used to produce US estimates of differences in resources consumed according to each growth scenario over the period 2000-2025. Sprawl produces a 21% increase in amount of undeveloped land converted to developed land (2.4 million acres) and approximately a 10% increase in local road lane-miles (188 300). Furthermore, sprawl causes about 10% more annual public service (fiscal) deficits ($4.2 billion US dollars) and 8% higher housing occupancy costs ($13 000 US dollars per dwelling unit). Managed growth can save significant amounts of human and natural resources with limited effects on traditional development procedures.

Revisiting classical design in engineering from a perspective of frugality.

PubMed

Rao, Balkrishna C

2017-05-01

The conservative nature of design in engineering has typically unleashed products fabricated with generous amounts of raw materials. This is epitomized by the factor of safety whose values higher than unity suggests various uncertainties of design that are tackled through material padding. This effort proposes a new factor of safety called the factor of frugality that could be used in ecodesign and which addresses both rigors of the classical design process and quantification of savings in materials going into a product. An example of frugal shaft design together with some other cases has been presented to explain the working of the factor of frugality . Adoption of the frugality factor would entail a change in design philosophy whereby designers would constantly make avail of a rigorous design process coupled with material-saving schemes for realizing products that are benign to the environment. Such a change in the foundations of design would abet the stewardship of earth in avoiding planetary boundaries since engineering influences a significant proportion of human endeavors.

Characteristics of MSW and heat energy recovery between residential and commercial areas in Seoul.

This paper analyzes the amount and characteristics of municipal solid waste (MSW) according to the inhabitant density of population and the business concentration in 25 districts in Seoul. Further, the heat energy recovery and avoided CO(2) emissions of four incineration plants located in residential and commercial areas in Seoul are examined. The amount of residential waste per capita tended to increase as the density of inhabitants decreased. The amount of commercial waste per capita tended to increase as the business concentration increased. The examination of the heat energy recovery characteristics indicated that the four incineration plants produced heat energy that depended on residential or commercial areas based on population and business. The most important result regarding avoided CO(2) emissions was that commercial areas with many office-type businesses had the most effective CO(2) emission savings by combusting 1 kg of waste. Assuming the full-scale operation of the four incineration plants, the amount of saved CO(2) emissions per year was 444 Gg CO(2) and 57,006 households in Seoul can be provided with heat energy equivalent to 542,711 Nm(3) of LNG.

Using an interrupted time series design and a census of births in California over a 6-year period, we show that state and federal laws passed in the late 1990s designed to increase the length of postpartum hospital stays reduced considerably the fraction of newborns that were discharged early. The law had little impact on re-admission rates for privately insured, vaginally delivered newborns, but reduced re-admission rates for privately insured c-section-delivered and Medicaid-insured vaginally delivered newborns by statistically significant amounts. Our calculations suggest the program was not cost saving.

In the wheat growth seasons of 2009 -2010 and 2010-2011, six border lengths of 10, 20, 40, 60, 80 and 100 m were installed in a wheat field to study the effects of different border lengths for irrigation on the water consumption characteristics and grain yield of wheat. The results showed that with the increasing border length from 10 to 80 m, the irrigation amount and the proportion of irrigation amount to total water consumption amount, the water content in 0-200 cm soil layers and the soil water supply capacity at anthesis stage, as well as the wheat grain yield and water use efficiency increased, while the soil water consumption amount and the water consumption amount of wheat from jointing to anthesis stages as well as the total water consumption amount decreased. At the border length of <80 m, the irrigation amount was smaller, and the water content in upper soil layers was lower, as compared with those at the border length of 80 m, which led to the wheat to absorb more water from deeper soil layers, and thus, the total water consumption increased. At the border length of 100 m, the irrigation amount, soil water consumption amount, and total water consumption amount all increased, and, due to the excessive irrigation amount and the uneven distribution of irrigation water when irrigated once, the 1000-grain mass, grain yield, and water use efficiency decreased significantly, which was not conductive to the water-saving and high-yield cultivation.

Distribution transformers convert power from the distribution system voltage to the end-customer voltage, which consists of residences, businesses, distributed generation, campus systems, and manufacturing facilities. Amorphous metal distribution transformers (AMDT) are also more expensive and heavier than conventional silicon steel distribution transformers. This and the difficulty to measure the benefit from energy efficiency and low awareness of the technology have hindered the adoption of AMDT. This report presents the cost savings for installing AMDT and the amount of energy saved based on the improved efficiency.

Reducing airflow energy use in multiple zone vav systems

NASA Astrophysics Data System (ADS)

Tukur, Ahmed Gidado

Variable Air Volume (VAV) systems are the most popular HVAC systems in commercial buildings. VAV systems are designed to deliver airflows at design conditions which only occur for a few hours in a year. Minimizing energy use in VAV systems requires reducing the amount of airflow delivered through the system at part load conditions. Air Handling Unit (AHU) fans are the major drivers of airflow in VAV systems and installing a Variable Frequency Drive (VFD) is the most common method of regulating airflow in VAV systems. A VFD drive does not necessarily save energy without use of an appropriate control strategy. Static pressure reset (SPR) is considered to be the most energy efficient control strategy for AHU fans with VFDs installed. The implementation of SPR however has many challenges; for example, rogue zones--zones which have faulty sensors or failed controls and actuators, system dynamics like hunting and system diversity. By investigating the parameters associated with the implementation of SPR in VAV systems, a new, improved, more stable SPR algorithm was developed and validated. This approach was further improved using Fault Detection and Diagnostics (FDD) to eliminate rogue zones. Additionally, a CO2-Demand Control Ventilation (DCV) based minimum airflow control was used to further reduce ventilation airflow and save more energy from SPR. Energy savings ranging from 25% to 51% were recorded in actual buildings with the new SPR algorithm. Finally, a methodology that utilizes historical VAV data was developed to estimate the potential savings that could be realized using SPR. The approach employed first determines an effective system loss coefficient as a function of mean damper position using the historical duct static pressure, VAV damper positions and airflows. Additionally, the historical data is used to identify the maximum mean duct damper position realizable as a result of insuring a sufficient number of VAVs are fully open at any time. Savings are estimated by shifting the damper distribution mean at each time to this maximum value and reducing the static pressure to achieve the same overall system airflow rate. The methodology was tested on three different buildings with varying system characteristics. Savings estimates correlated well to the savings actually realized from SPR. This result has significant implications for energy service providers, who could use the predictions to guarantee savings from SPR.

Food waste disposal units in UK households: the need for policy intervention.

The EU Landfill Directive requires Member States to reduce the amount of biodegradable waste disposed of to landfill. This has been a key driver for the establishment of new waste management options, particularly in the UK, which in the past relied heavily on landfill for the disposal of municipal solid waste (MSW). MSW in the UK is managed by Local Authorities, some of which in a less conventional way have been encouraging the installation and use of household food waste disposal units (FWDs) as an option to divert food waste from landfill. This study aimed to evaluate the additional burden to water industry operations in the UK associated with this option, compared with the benefits and related savings from the subsequent reductions in MSW collection and disposal. A simple economic analysis was undertaken for different FWD uptake scenarios, using the Anglian Region as a case study. Results demonstrated that the significant savings from waste collection arising from a large-scale uptake of FWDs would outweigh the costs associated with the impacts to the water industry. However, in the case of a low uptake, such savings would not be enough to cover the increased costs associated with the wastewater provision. As a result, this study highlights the need for policy intervention in terms of regulating the use of FWDs, either promoting them as an alternative to landfill to increase savings from waste management, or banning them as a threat to wastewater operations to reduce potential costs to the water industry.

An Evaluation of the Consumer Costs and Benefits of Energy Efficiency Resource Standards

NASA Astrophysics Data System (ADS)

Lessans, Mark D.

Of the modern-day policies designed to encourage energy efficiency, one with a significant potential for impact is that of Energy Efficiency Resource Standards (EERS). EERS policies place the responsibility for meeting an efficiency target on the electric and gas utilities, typically setting requirements for annual reductions in electricity generation or gas distribution to customers as a percentage of sales. To meet these requirements, utilities typically implement demand-side management (DSM) programs, which encourage energy efficiency at the customer level through incentives and educational initiatives. In Maryland, a statewide EERS has provided for programs which save a significant amount of energy, but is ultimately falling short in meeting the targets established by the policy. This study evaluates residential DSM programs offered by Pepco, a utility in Maryland, for cost-effectiveness. However, unlike most literature on the topic, analysis focuses on the costs-benefit from the perspective of the consumer, and not the utility. The results of this study are encouraging: the majority of programs analyzed show that the cost of electricity saved, or levelized cost of saved energy (LCSE), is less expensive than the current retail cost of electricity cost in Maryland. A key goal of this study is to establish a metric for evaluating the consumer cost-effectiveness of participation in energy efficiency programs made available by EERS. In doing so, the benefits of these programs can be effectively marketed to customers, with the hope that participation will increase. By increasing consumer awareness and buy-in, the original goals set out through EERS can be realized and the policies can continue to receive support.

Application of organic waste materials such as food processing and serving industry cooking oil waste (OFW) can recycle soil nitrate nitrogen (NO(3)-N), which is otherwise prone to leaching after the harvest of crop. Nitrogen (N) recycling will not only reduce the amount of N fertilizer application for corn crop production but is also expected to mitigate green house gas (GHG) emissions by saving energy to be used for the production of the same amount of industrial fertilizer N required for the growth of corn crop. Application of OFW at 10Mg solid ha(-1)y(-1) conserved 68 kg N ha(-1)y(-1) which ultimately saved 134 L diesel ha(-1)y(-1), which would otherwise be used for the production of fertilizer N as urea. Average fossil energy substitution value (FESV) of N conserved/recycled was calculated to be 93 US$ ha(-1)y(-1), which is about 13 million US$y(-1). Potential amount of GHG mitigation through the application of OFW to agricultural soils in Canada is estimated to be 57 Gg CO(2)Eq y(-1).

Objective To estimate the willingness to pay (WTP) per quality-adjusted life year (QALY) value for life-saving treatments and to determine factors affecting the WTP per QALY value. Design A cross-sectional survey with multistage sampling and face-to-face interviews. Setting General population in the southern part of Thailand. Participants A total of 600 individuals were included in the study. Only 554 (92.3%) responses were usable for data analyses. Outcome measure Participants were asked for the maximum amount of WTP value for life-saving treatments by an open-ended question. EQ-5D-3L and visual analogue scale (VAS) were used to estimate additional QALY. Results The amount of WTP values varied from 0 to 720 000 Baht/year (approximately 32 Baht=US$1). The averages of additional QALY obtained from VAS and EQ-5D-3L were only slightly different (0.872 and 0.853, respectively). The averages of WTP per QALY obtained from VAS and EQ-5D-3L were 244720 and 243120 Baht/QALY, respectively. As compared to male participants, female participants were more likely to pay less for an additional QALY (p=0.007). In addition, participants with higher household incomes tended to have higher WTP per QALY values (p<0.001). Conclusions Our study added another WTP per QALY value specifically for life-saving treatments, which would complement the current cost-effectiveness threshold used in Thailand and optimise patient access to innovative treatments or technologies.

Distillation systems are energy and power intensive processes and contribute significantly to the greenhouse gases emissions (e.g. carbon dioxide). Reducing CO2 emissions is an absolute necessity and expensive challenge to the chemical process industries in orderto meetthe environmental targets as agreed in the Kyoto Protocol. A simple model for the calculation of CO2 emissions from heat-integrated distillation systems is introduced, considering typical process industry utility devices such as boilers, furnaces, and turbines. Furnaces and turbines consume large quantities of fuels to provide electricity and process heats. As a result, they produce considerable amounts of CO2 gas to the atmosphere. Boilers are necessary to supply steam for heating purposes; besides, they are also significant emissions contributors. The model is used in an optimization-based approach to optimize the process conditions of an existing crude oil atmospheric tower in order to reduce its CO2 emissions and energy demands. It is also applied to generate design options to reduce the emissions from a novel internally heat-integrated distillation column (HIDiC). A gas turbine can be integrated with these distillation systems for larger emissions reduction and further energy savings. Results show that existing crude oil installations can save up to 21% in energy and 22% in emissions, when the process conditions are optimized. Additionally, by integrating a gas turbine, the total emissions can be reduced further by 48%. Internal heat-integrated columns can be a good alternative to conventional heat pump and other energy intensive close boiling mixtures separations. Energy savings can reach up to 100% with respect to reboiler heat requirements. Emissions of these configurations are cut down by up to 83%, compared to conventional units, and by 36%, with respect to heat pump alternatives. Importantly, cost savings and more profit are gained in parallel to emissions minimization.

Landfilling of waste: accounting of greenhouse gases and global warming contributions.

Manfredi, Simone; Tonini, Davide; Christensen, Thomas H; Scharff, Heijo

2009-11-01

Accounting of greenhouse gas (GHG) emissions from waste landfilling is summarized with the focus on processes and technical data for a number of different landfilling technologies: open dump (which was included as the worst-case-scenario), conventional landfills with flares and with energy recovery, and landfills receiving low-organic-carbon waste. The results showed that direct emissions of GHG from the landfill systems (primarily dispersive release of methane) are the major contributions to the GHG accounting, up to about 1000 kg CO(2)-eq. tonne( -1) for the open dump, 300 kg CO(2)-eq. tonne( -1) for conventional landfilling of mixed waste and 70 kg CO(2)-eq. tonne(-1) for low-organic-carbon waste landfills. The load caused by indirect, upstream emissions from provision of energy and materials to the landfill was low, here estimated to be up to 16 kg CO(2)-eq. tonne(-1). On the other hand, utilization of landfill gas for electricity generation contributed to major savings, in most cases, corresponding to about half of the load caused by direct GHG emission from the landfill. However, this saving can vary significantly depending on what the generated electricity substitutes for. Significant amounts of biogenic carbon may still be stored within the landfill body after 100 years, which here is counted as a saved GHG emission. With respect to landfilling of mixed waste with energy recovery, the net, average GHG accounting ranged from about -70 to 30 kg CO(2)-eq. tonne(- 1), obtained by summing the direct and indirect (upstream and downstream) emissions and accounting for stored biogenic carbon as a saving. However, if binding of biogenic carbon was not accounted for, the overall GHG load would be in the range of 60 to 300 kg CO(2)-eq. tonne( -1). This paper clearly shows that electricity generation as well as accounting of stored biogenic carbon are crucial to the accounting of GHG of waste landfilling.

Background Lost productivity represents a considerable portion of the total economic burden of colorectal cancer (CRC), but cost-effectiveness studies of CRC prevention and control have not included these costs and therefore underestimate potential savings from CRC prevention and control. Purpose To use microsimulation modeling study to estimate and project productivity costs of CRC and to model the savings from four approaches to reducing CRC incidence and mortality: risk factor reduction, improved screening, improved treatment, and a simultaneous approach where all three strategies are implemented. Methods A model was developed to project productivity losses from CRC using the U.S. population with CRC incidence and mortality projected through the year 2020. Outcome measures were CRC mortality, morbidity, and productivity savings. Results With 2005 levels in risk factors, screening, and treatment, 48,748 CRC deaths occurred in 2010, amounting to $21 billion of lost productivity. Using prevention and treatment strategies simultaneously, 3586 deaths could have been avoided in 2010, leading to a savings of $1.4 billion. Cumulatively, by 2020, simultaneous strategies that reduce risk factors and increase screening and treatment could result in 101,353 deaths avoided and $33.9 billion in savings in reduced productivity loss. Improved screening rates alone led to nearly $14.7 billion in savings between 2005 and 2020, followed by risk factor reduction ($12.4 billion) and improved treatment ($8.4 billion). Conclusions The savings in productivity loss from strategies to reduce CRC incidence and mortality are substantial, providing evidence that CRC prevention and control strategies are likely to be cost-saving.

In high energy physics (HEP) event simulations, petabytes of data are processed and stored requiring millions of CPU-years. This enormous demand for computing resources is handled by centers distributed worldwide, which form part of the LHC computing grid. The consumption of such an important amount of resources demands for an efficient production of simulation and for the early detection of potential errors. In this article we present a new monitoring framework for grid environments, which polls a measure of data quality during job execution. This online monitoring facilitates the early detection of configuration errors (specially in simulation parameters), and may thus contribute to significant savings in computing resources.

The use of an automated external defibrillator (AED) prior to EMS arrival can increase 30-day survival in out-of-hospital cardiac arrest (OHCA) significantly. Drones or unmanned aerial vehicles (UAV) can fly with high velocity and potentially transport devices such as AEDs to the site of OHCAs. The aim of this explorative study was to investigate the feasibility of a drone system in decreasing response time and delivering an AED. Data of Global Positioning System (GPS) coordinates from historical OHCA in Stockholm County was used in a model using a Geographic Information System (GIS) to find suitable placements and visualize response times for the use of an AED equipped drone. Two different geographical models, urban and rural, were calculated using a multi-criteria evaluation (MCE) model. Test-flights with an AED were performed on these locations in rural areas. In total, based on 3,165 retrospective OHCAs in Stockholm County between 2006-2013, twenty locations were identified for the potential placement of a drone. In a GIS-simulated model of urban OHCA, the drone arrived before EMS in 32 % of cases, and the mean amount of time saved was 1.5 min. In rural OHCA the drone arrived before EMS in 93 % of cases with a mean amount of time saved of 19 min. In these rural locations during (n = 13) test flights, latch-release of the AED from low altitude (3-4 m) or landing the drone on flat ground were the safest ways to deliver an AED to the bystander and were superior to parachute release. The difference in response time for EMS between urban and rural areas is substantial, as is the possible amount of time saved using this UAV-system. However, yet another technical device needs to fit into the chain of survival. We know nothing of how productive or even counterproductive this system might be in clinical reality. To use drones in rural areas to deliver an AED in OHCA may be safe and feasible. Suitable placement of drone systems can be designed by using GIS models. The use of an AED equipped drone may have the potential to reduce time to defibrillation in OHCA.

Use of recuperator in heat producing plants for utilization of natural gas combustion products allows to achieve the saving of gas fuel and also provides for environmental sanitation. Decrease of the volumes of natural gas combustion due to utilization of heat provides not only for reduction of harmful agents in the combustion products discharged into the atmosphere, but also creates conditions for increase of energy saving in heating processes of heat producing plants due to air overheating in the recuperator. Grapho-analytical method of determination of energy saving and reduction of discharges of combustion products into the atmosphere is represented in the article. Multifunctional diagram is developed, allowing to determine simultaneously savings from reduction of volumes of natural gas combusted and from reduction of amounts of harmful agents in the combustion products discharged into the atmosphere. Calculation of natural gas economy for heat producing plant taking into consideration certain capacity is carried out.

Matrix-assisted laser desorption ionization–time of flight (MALDI-TOF) mass spectrometry (MS) is an emerging technology for rapid identification of bacterial and fungal isolates. In comparison to conventional methods, this technology is much less labor intensive and can provide accurate and reliable results in minutes from a single isolated colony. We compared the cost of performing the bioMérieux Vitek MALDI-TOF MS with conventional microbiological methods to determine the amount saved by the laboratory by converting to the new technology. Identification costs for 21,930 isolates collected between April 1, 2013, and March 31, 2014, were directly compared for MALDI-TOF MS and conventional methodologies. These isolates were composed of commonly isolated organisms, including commonly encountered aerobic and facultative bacteria and yeast but excluding anaerobes and filamentous fungi. Mycobacterium tuberculosis complex and rapidly growing mycobacteria were also evaluated for a 5-month period during the study. Reagent costs and a total cost analysis that included technologist time in addition to reagent expenses and maintenance service agreement costs were analyzed as part of this study. The use of MALDI-TOF MS equated to a net savings of $69,108.61, or 87.8%, in reagent costs annually compared to traditional methods. When total costs are calculated to include technologist time and maintenance costs, traditional identification would have cost $142,532.69, versus $68,886.51 with the MALDI-TOF MS method, resulting in a laboratory savings of $73,646.18, or 51.7%, annually by adopting the new technology. The initial cost of the instrument at our usage level would be offset in about 3 years. MALDI-TOF MS not only represents an innovative technology for the rapid and accurate identification of bacterial and fungal isolates, it also provides a significant cost savings for the laboratory.

Accountable care organizations (ACOs) have diverse contracting arrangements and have displayed wide variations in their performance. Using data from national surveys of 399 ACOs, we examined differences between the 228 commercial ACOs (those with commercial payer contracts) and the 171 noncommercial ACOs (those with only public contracts, such as with Medicare or Medicaid). Commercial ACOs were significantly larger and more integrated with hospitals, and had lower benchmark expenditures and higher quality scores, compared to noncommercial ACOs. Among all of the ACOs, there was low uptake of quality and efficiency activities. However, commercial ACOs reported more use of disease monitoring tools, patient satisfaction data, and quality improvement methods than did noncommercial ACOs. Few ACOs reported having high-level performance monitoring capabilities. About two-thirds of the ACOs had established processes for distributing any savings accrued, and these ACOs allocated approximately the same amount of savings to the ACOs themselves, participating member organizations, and physicians. Our findings demonstrate that ACO delivery systems remain at a nascent stage. Structural differences between commercial and noncommercial ACOs are important factors to consider as public policy efforts continue to evolve. PMID:27702959

Directions for lunar construction - A derivation of requirements from a construction scenario analysis

This paper provides an initial trade-off study among several lunar construction options available to the Space Exploration Initiative. The relative time effectiveness of Extra-Vehicular Activity (EVA), Intra-Vehicular Activity (IVA), and Earth-based remote control assembly and construction methods are studied. Also considered is whether there is any construction time savings to building roads in advance, or surveying the construction sites with orbiters or rovers in advance. The study was conducted by adding detail to a potentially real scenario - a nuclear power plant - and applying time multipliers for the various control options and terrain alternatives, provided by roboticists among the authors. The authors conclude that IVA is a faster construction method than either EVA or construction conducted remotely from Earth. Surveying proposed sites in advance, with orbiters and rovers, provides a significant time savings through adding to certainty, and therefore may be cost effective. Developing a heavy-lift launch capability and minimizing assembly and construction processes by landing large payloads is probably worthwhile to the degree possible, as construction activities would use a large amount of surface operations time.

Evapotranspiration management based on the application of SWAT for balancing water consumption: A case study in Guantao, China

NASA Astrophysics Data System (ADS)

Liu, Bin; Gan, Hong

2018-06-01

Rapid social and economic development results in increased demand for water resources. This can lead to the unsustainable development and exploitation of water resources which in turn causes significant environmental problems. Conventional water resource management approaches, such as supply and demand management strategies, frequently fail to restore regional water balance. This paper introduces the concept of water consumption balance, the balance between actual evapotranspiration (ET) and target ET, and establishes a framework to realize regional water balance. The framework consists of three stages: (1) determination of target ET and actual ET; (2) quantification of the water-saving requirements for the region; and (3) reduction of actual ET by implementing various water saving management strategies. Using this framework, a case study was conducted for Guantao County, China. The SWAT model was utilized to aid in the selection of the best water saving management strategy by comparing the ET of different irrigation methods and crop pattern adjustments. Simulation results revealed that determination of SWAT model parameters using remote sensing ET is feasible and that the model is a valuable tool for ET management. Irrigation was found to have a greater influence on the ET of winter wheat as compared to that of maize, indicating that reduction in winter wheat cultivation is the most effective way to reduce regional ET. However, the effect of water-saving irrigation methods on the reduction of ET was not obvious. This indicates that it would be difficult to achieve regional ET reduction using water-saving irrigation methods only. Furthermore, selecting the best water saving management strategy by relying solely on the amount of reduced ET was insufficient, because it ignored the impact of water conservation measures on the livelihood of the agricultural community. Incorporating these considerations with our findings, we recommend changing the current irrigation method to sprinkler irrigation and replacing 20% of the winter wheat-maize cultivated area with cotton, as the best strategy to achieve water balance in the study area.

How much could be saved in Chinese hospitals in procurement of anti-hypertensives and anti-diabetics?

Efficient use of government funding has been increasingly relevant for the success and sustainability of ongoing health-system reform in China; however, as there is no generic substitution policy, patients and basic health-insurance programs pay more for public-preferred brand originators. Such phenomenon is especially typical in public hospitals. The objective of this study is to estimate the potential cost savings in procurement by Chinese public hospitals when switching from brand originators of anti-hypertensive and anti-diabetic medications to their generic equivalents between 2012-2014. IMS Health volume and value consumption data (IMS China Hospitals Audit system 2012-2014) were used, which covered all Chinese hospitals with 100 beds and above. The top 60% IMS volume consumption of respective anti-hypertensive and anti-diabetic medication with unique dosage form and strength were included. The potential cost savings were calculated from a switch of brand originators with their generic equivalents on the Chinese and international market. An independent sample t-test was conducted to compare the difference of proportion of cost savings in value between the Chinese and international market. An average of 44% (US$44 million) and 87% (US$90 million) and a total of US$1.4 and 2.8 billion (2014 US$) could be saved from a switch from originator brand anti-hypertensives and anti-diabetics to domestically and internationally available generic equivalents, respectively. The differences of cost savings (in proportion) between domestic and international market were statistically significant (α = 0.005, p = 0.003, p = 0.002, p = 0.000). Expensive brand originators dominated the anti-hypertensive and anti-diabetic market in Chinese hospitals between 2012-2014. Preference of brand originators wastes a huge amount of health resources in China and these limited resources could have been used more efficiently. As one of the world's key generic suppliers, if China wants to use its health resource more efficiently on medicines, comprehensive measures are needed to address both demand-side (consumers' low trust in the quality of local generics) and supply-side barriers (health professionals' preference of brand originators).

Hot topic: Definition and implementation of a breeding value for feed efficiency in dairy cows.

A new breeding value that combines the amount of feed saved through improved metabolic efficiency with predicted maintenance requirements is described. The breeding value includes a genomic component for residual feed intake (RFI) combined with maintenance requirements calculated from either a genomic or pedigree estimated breeding value (EBV) for body weight (BW) predicted using conformation traits. Residual feed intake is only available for genotyped Holsteins; however, BW is available for all breeds. The RFI component of the "feed saved" EBV has 2 parts: Australian calf RFI and Australian lactating cow RFI. Genomic breeding values for RFI were estimated from a reference population of 2,036 individuals in a multi-trait analysis including Australian calf RFI (n=843), Australian lactating cow RFI (n=234), and UK and Dutch lactating cow RFI (n=958). In all cases, the RFI phenotypes were deviations from a mean of 0, calculated by correcting dry matter intake for BW, growth, and milk yield (in the case of lactating cows). Single nucleotide polymorphism effects were calculated from the output of genomic BLUP and used to predict breeding values of 4,106 Holstein sires that were genotyped but did not have RFI phenotypes themselves. These bulls already had BW breeding values calculated from type traits, from which maintenance requirements in kilograms of feed per year were inferred. Finally, RFI and the feed required for maintenance (through BW) were used to calculate a feed saved breeding value and expressed as the predicted amount of feed saved per year. Animals that were 1 standard deviation above the mean were predicted to eat 66 kg dry matter less per year at the same level of milk production. In a data set of genotyped Holstein sires, the mean reliability of the feed saved breeding value was 0.37. For Holsteins that are not genotyped and for breeds other than Holsteins, feed saved is calculated using BW only. From April 2015, feed saved has been included as part of the Australian national selection index, the Balanced Performance Index (BPI). Selection on the BPI is expected to lead to modest gains in feed efficiency. Copyright © 2015 American Dairy Science Association. Published by Elsevier Inc. All rights reserved.

Quality control (QC) validation is an essential tool in total quality management of a veterinary clinical pathology laboratory. Cost-analysis can be a valuable technique to help identify an appropriate QC procedure for the laboratory, although this has never been reported in veterinary medicine. The aim of this study was to determine the applicability of the Six Sigma Quality Cost Worksheets in the evaluation of possible candidate QC rules identified by QC validation. Three months of internal QC records were analyzed. EZ Rules 3 software was used to evaluate candidate QC procedures, and the costs associated with the application of different QC rules were calculated using the Six Sigma Quality Cost Worksheets. The costs associated with the current and the candidate QC rules were compared, and the amount of cost savings was calculated. There was a significant saving when the candidate 1-2.5s, n = 3 rule was applied instead of the currently utilized 1-2s, n = 3 rule. The savings were 75% per year (£ 8232.5) based on re-evaluating all of the patient samples in addition to the controls, and 72% per year (£ 822.4) based on re-analyzing only the control materials. The savings were also shown to change accordingly with the number of samples analyzed and with the number of daily QC procedures performed. These calculations demonstrated the importance of the selection of an appropriate QC procedure, and the usefulness of the Six Sigma Costs Worksheet in determining the most cost-effective rule(s) when several candidate rules are identified by QC validation. © 2014 American Society for Veterinary Clinical Pathology and European Society for Veterinary Clinical Pathology.

Fall-related injuries and health risks associated with reduced mobility or physical inactivity account for significant costs to the U.S. healthcare system. The widely disseminated lay-led A Matter of Balance (MOB) program aims to help older adults reduce their risk of falling and associated activity limitations. This study examined effects of MOB participation on health service utilization and costs for Medicare beneficiaries, as a part of a larger effort to understand the value of community-based prevention and wellness programs for Medicare. A controlled retrospective cohort study was conducted in 2012-2013, using 2007-2011 MOB program data and 2006-2013 Medicare data. It investigated program effects on falls and fall-related fractures, and health service utilization and costs (standardized to 2012 dollars), of 6,136 Medicare beneficiaries enrolled in MOB from 2007 through 2011. A difference-in-differences analysis was employed to compare outcomes of MOB participants with matched controls. MOB participation was associated with total medical cost savings of $938 per person (95% CI=$379, $1,498) at 1 year. Savings per person amounted to $517 (95% CI=$265, $769) for unplanned hospitalizations; $81 for home health care (95% CI=$20, $141); and $234 (95% CI=$55, $413) for skilled nursing facility care. Changes in the incidence of falls or fall-related fractures were not detected, suggesting that cost savings accrue through other mechanisms. This study suggests that MOB and similar prevention programs have the potential to reduce Medicare costs. Further research accounting for program delivery costs would help inform the development of Medicare-covered preventive benefits. Copyright © 2015 American Journal of Preventive Medicine.

Anesthetic preoperative evaluation clinics (APECs) are relatively new institutions. Although cost effective, APECs have not been universally adopted in Europe. The aim of this study was to compare preoperative anesthetic assessment in wards with an APEC, assessing time, information gain, patient satisfaction and secondary costs. Two hundred and seven inpatients were randomized to be assessed at the APEC or on the ward by the same two senior anesthetists. The outcomes measured were the length of time for each consultation, the amount of information passed on to patients and the level of patient satisfaction. The consultation time was used to calculate impact on direct costs. A multivariate analysis was conducted to detect confounding variables. Ninety-four patients were seen in the APEC, and 78 were seen on the ward. The total time for the consultation was shorter for the APEC (mean 8.4 minutes [P<0.01]), and we calculated savings of 6.4 Euro per patient. More information was passed on to the patients seen in the APEC (P<0.01). The general satisfaction scores were comparable between groups. A multivariate analysis found that the consultation time was significantly influenced by the type of anesthesia, the magnitude of the operation and the location of the consultation. Gain in information was significantly influenced by age, education and the location of the visit. The APEC reduced consultation times and costs and had a positive impact on patient education. The cost savings are related to personnel costs and, therefore, are independent of other potential savings of an APEC, whereas global patient satisfaction remains unaltered.

Navigation API Route Fuel Saving Opportunity Assessment on Large-Scale Real-World Travel Data for Conventional Vehicles and Hybrid Electric Vehicles: Preprint

DOE Office of Scientific and Technical Information (OSTI.GOV)

Zhu, Lei; Holden, Jacob; Gonder, Jeffrey D

The green routing strategy instructing a vehicle to select a fuel-efficient route benefits the current transportation system with fuel-saving opportunities. This paper introduces a navigation API route fuel-saving evaluation framework for estimating fuel advantages of alternative API routes based on large-scale, real-world travel data for conventional vehicles (CVs) and hybrid electric vehicles (HEVs). The navigation APIs, such Google Directions API, integrate traffic conditions and provide feasible alternative routes for origin-destination pairs. This paper develops two link-based fuel-consumption models stratified by link-level speed, road grade, and functional class (local/non-local), one for CVs and the other for HEVs. The link-based fuel-consumption modelsmore » are built by assigning travel from a large number of GPS driving traces to the links in TomTom MultiNet as the underlying road network layer and road grade data from a U.S. Geological Survey elevation data set. Fuel consumption on a link is calculated by the proposed fuel consumption model. This paper envisions two kinds of applications: 1) identifying alternate routes that save fuel, and 2) quantifying the potential fuel savings for large amounts of travel. An experiment based on a large-scale California Household Travel Survey GPS trajectory data set is conducted. The fuel consumption and savings of CVs and HEVs are investigated. At the same time, the trade-off between fuel saving and time saving for choosing different routes is also examined for both powertrains.« less

The Medicare cost savings from the use of bevacizumab in the United States for the treatment of exudative age-related macular degeneration (AMD) were estimated by replacing the use of bevacizumab with ranibizumab and aflibercept. Retrospective trend study. Main outcome measures were spending by Medicare as tracked by Current Procedural Terminology (CPT) codes for intravitreal injections (67028) and treatment-specific J-codes (J0178, J2778, J9035, J3490 and J3590) for inhibitors of vascular endothelial growth factor. These claims were identified from the Medicare Provider Utilization and Payment Data from the Centers for Medicare and Medicaid Services among fee-for-service (FFS) Medicare beneficiaries from 2012 - 2015. The 2008 claims were acquired from the 100% fee-for-service (FFS) Part B Medicare Claims File. The use of bevacizumab from 2008 to 2015 resulted in an estimated savings of $17.3 billion, which corresponded to a $13.8 billion savings to Medicare and a $3.5 billion savings to patients. This amount underestimated the actual cost-savings to Medicare providers since approximately 30% of Medicare-eligible recipients received care within Medicare Advantage plans and were not included in this analysis. The cost savings from the use of bevacizumab from 2008-2015 for Medicare fee-for-service patients undergoing treatment for exudative AMD was estimated at $17.3 billion. Additional savings over the $17.3 billion would have accrued from the use of bevacizumab if diagnostic categories such as diabetic macular edema and retinal vein occlusion were included in this study.

Blood Saving Campaign is a campaign to lessen the risk of intra- and post-operative blood transfusion by decreasing the amount of blood loss during surgery and at the same time will lessen the risk of transmission of blood born diseases. The blood saved can be used to treat those afflicted with diseases such as hemophilia and aplastic anemia where blood transfusion is imperative for the survival of the patient. At the 7th forum of WFSLMS held in Germany 2003, the steering committee has evolved to an organizing committee of WFSLMS. The aim of WFSLMS is to contribute to the health and welfare of mankind through the merit of minimum tissue damage and high efficacy of hemostasis in laser medicine. Therefore we also organized a Laser Blood Saving Campaign (Laser B-SAC) committee within WFSLMS at the same congress. The methods of laser blood saving are divided into 4 categories. 1. Surgical Laser Treatment (HLLT). 2. Non-surgical Laser Therapy (LLLT). 3. Laser Treatment with Newly Developed Laser Machines. 4. Laser Treatment with Newly Developed Techniques. I will mention on the History of B-SAC, Action Plan of B-SAC and so on.

Drug product selection: the Florida experience.

Drug product selection, the act of selecting and dispensing a lower cost generically equivalent product to that prescribed, is made possible in 46 states through recently enacted legislation. Florida's legislation is unique in that it requires pharmacists to product select under certain circumstances. This study reports on the results of a review of the Florida experience approximately one year after enactment of its drug product selection legislation. Nearly 132,000 prescriptions were sampled from 60 pharmacies during a four-month study period. This represents one per cent of all new prescriptions in the state and a three per cent sample of community pharmacies. Study results indicate that drug product selection on the average saves the consumer $1.92 per prescription. Further, under the provisions of this law the majority of cost savings (average reductions in acquisition costs between prescribed and dispensed products) are being passed along as savings to the consumer. During the four-month study period this amounted to a total prescription cost savings of nearly $425,000. Drug product selection occurs in approximately two per cent of all new prescriptions which compares favorably with results reported from other states but also suggests that additional savings can be realized under such legislation.

The surgical treatment capacity of a hospital constitutes a significant restriction in the capability to deal with critically injured patients from multiple or mass casualty incidents (MCI). With regard to the time needed for life-saving operative interventions there are no basic reference values available in the literature, which can aid in detailed planning for management of mass casualty incidents. The data of 20,815 trauma patients, recorded in the trauma registry hosted by the German Association for Trauma Surgery DGU, were analyzed to extract the median duration of life-saving surgical interventions carried out in an operating theatre. Inclusion criteria were an ISS > or = 16 and the performance of relevant ICPM coded procedures within 6 h after trauma room admission. Orthopedic procedures as well as the placement of ICP catheters and chest tubes or performance of laparoscopies were not included. Complete data sets with the required variables were available from 9,988 trauma patients with an ISS > or = 16, and included 7,907 interventions that took place within 6 h after hospital admission. From among 1,228 patients 1,793 operations could be identified as relevant life-saving emergency operations. Acute injury to the abdomen was the major cause accounting for 54.1% of all emergency surgical procedures with a median intervention duration of 137 min followed by head injuries accounting for 26.3% with a median duration of 110 min. Interventions in the pelvis amounted to 11.5% taking an average of 136 min, 5.0% were in the thorax requiring 91 min and 3.1% major amputations with 142 min. The average cut to suture time for all emergency surgical interventions was 130 min. A prerequisite for estimating the surgical operation capacity for critically injured patients of an MCI is the number of OR teams available during and outside of the normal working hours of the hospital. The average operation time of 130 min calculated from investigation of 1,793 emergency life-saving surgical procedures provides a realistic guideline. Used in combination with the number of available OR teams the prospective treatment capacity can be estimated and projected into an actual incident admission capacity. The identification and numerical value of such significant variables are the basis for operations research and realistic planning in emergency and disaster medicine.

The energy impacts of solar heating.

Whipple, C

1980-04-18

The energy required to build and install solar space- and water-heating equipment is compared to the energy it saves under two solar growth paths corresponding to high and low rates of implementation projected by the Domestic Policy Review of Solar Energy. For the rapid growth case, the cumulative energy invested to the year 2000 is calculated to be (1/2) to 1(1/2) times the amount saved. An impact of rapid solar heating implementation is to shift energy demand from premium heating fuels (natural gas and oil) to coal and nuclear power use in the industries that provide materials for solar equipment.

Reduction of water pollutant emissions and energy consumption is regarded as a key environmental objective for the pulp and paper industry. The paper develops a bottom-up model called the Industrial Water Pollutant Control and Technology Policy (IWPCTP) based on an industrial technology simulation system and multiconstraint technological optimization. Five policy scenarios covering the business as usual (BAU) scenario, the structural adjustment (SA) scenario, the cleaner technology promotion (CT) scenario, the end-treatment of pollutants (EOP) scenario, and the coupling measures (CM) scenario have been set to describe future policy measures related to the development of the pulp and paper industry from 2010-2020. The outcome of this study indicates that the energy saving amount under the CT scenario is the largest, while that under the SA scenario is the smallest. Under the CT scenario, savings by 2020 include 70 kt/year of chemical oxygen demand (COD) emission reductions and savings of 7443 kt of standard coal, 539.7 ton/year of ammonia nitrogen (NH4-N) emission reductions, and savings of 7444 kt of standard coal. Taking emission reductions, energy savings, and cost-benefit into consideration, cleaner technologies like highly efficient pulp washing, dry and wet feedstock preparation, and horizontal continuous cooking, medium and high consistency pulping and wood dry feedstock preparation are recommended.

Health savings accounts and health reimbursement arrangements: assets, account balances, and rollovers, 2006-2011.

ASSET LEVELS GROWING: In 2011, there was $12.4 billion in health savings accounts (HSAs) and health reimbursement arrangements (HRAs), spread across 8.4 million accounts, according to data from the 2011 EBRI/MGA Consumer Engagement in Health Care Survey, sponsored by EBRI and Matthew Greenwald & Associates. This is up from 2006, when there were 1.3 million accounts with $873.4 million in assets, and 2010, when 5.4 million accounts held $7.3 billion in assets. AFTER LEVELING OFF, AVERAGE ACCOUNT BALANCES INCREASED: After average account balances leveled off in 2008 and 2009, and fell slightly in 2010, they increased in 2011. In 2006, account balances averaged $696. They increased to $1,320 in 2007, a 90 percent increase. Account balances averaged $1,356 in 2008 and $1,419 in 2009, 3 percent and 5 percent increases, respectively. In 2010, average account balances fell to $1,355, down 4.5 percent from the previous year. In 2011, average account balances increased to $1,470, a 9 percent increase from 2010. TOTAL AND AVERAGE ROLLOVERS INCREASE: After declining to $1,029 in 2010, average rollover amounts increased to $1,208 in 2011. Total assets being rolled over increased as well: $6.7 billion was rolled over in 2011, up from $3.7 billion in 2010. The percentage of individuals without a rollover remained at 13 percent in 2011. HEALTHY BEHAVIOR DOES NOT MEAN HIGHER ACCOUNT BALANCES AND HIGHER ROLLOVERS: Individuals who smoke have more money in their accounts than those who do not smoke. In contrast, obese individuals have less money in their account than the nonobese. There is very little difference in account balances by level of exercise. Very small differences were found in account balances and rollover amounts between individuals who used cost or quality information, compared with those who did not use such information. However, next to no relationship was found between either account balance or rollover amounts and various cost-conscious behaviors. When a difference was found, those exhibiting the cost-conscious behavior were found to have lower account balances and rollover amounts. DIFFERENCES IN ACCOUNT BALANCES: Men have higher account balances than women, older individuals have higher account balances than younger ones, account balances increase with household income, and education has a significant impact on account balances independent of income and other variables. DIFFERENCES IN ROLLOVER AMOUNTS: Men rolled over more money than women, and older individuals had higher rollover amounts than younger individuals. Rollover amounts increase with household income and education, and individuals with single coverage rolled over a slightly higher amount than those with family coverage.

Estimating the economic burden of disasters requires appropriate models that account for key characteristics and decision making needs. Natural disasters in 2011 resulted in $366 billion in direct damages and 29,782 fatalities worldwide. Average annual losses in the US amount to about $55 billion. Enhancing community and system resilience could lead to significant savings through risk reduction and expeditious recovery. The management of such reduction and recovery is facilitated by an appropriate definition of resilience and associated metrics with models for examining the economics of resilience. This paper provides such microeconomic models, compares them, examines their sensitivities to key parameters, and illustrates their uses.

In communication complexity, a number of distant parties have the task of calculating a distributed function of their inputs, while minimizing the amount of communication between them. It is known that with quantum resources, such as entanglement and quantum channels, one can obtain significant reductions in the communication complexity of some tasks. In this work, we study the role of the quantum superposition of the direction of communication as a resource for communication complexity. We present a tripartite communication task for which such a superposition allows for an exponential saving in communication, compared to one-way quantum (or classical) communication; the advantage also holds when we allow for protocols with bounded error probability.

A Novel Sensor Platform Matching the Improved Version of IPMVP Option C for Measuring Energy Savings

PubMed Central

Tseng, Yen-Chieh; Lee, Da-Sheng; Lin, Cheng-Fang; Chang, Ching-Yuan

2013-01-01

It is easy to measure energy consumption with a power meter. However, energy savings cannot be directly computed by the powers measured using existing power meter technologies, since the power consumption only reflects parts of the real energy flows. The International Performance Measurement and Verification Protocol (IPMVP) was proposed by the Efficiency Valuation Organization (EVO) to quantify energy savings using four different methodologies of A, B, C and D. Although energy savings can be estimated following the IPMVP, there are limitations on its practical implementation. Moreover, the data processing methods of the four IPMVP alternatives use multiple sensors (thermometer, hygrometer, Occupant information) and power meter readings to simulate all facilities, in order to determine an energy usage benchmark and the energy savings. This study proposes a simple sensor platform to measure energy savings. Using usually the Electronic Product Code (EPC) global standard, an architecture framework for an information system is constructed that integrates sensors data, power meter readings and occupancy conditions. The proposed sensor platform is used to monitor a building with a newly built vertical garden system (VGS). A VGS shields solar radiation and saves on energy that would be expended on air-conditioning. With this platform, the amount of energy saved in the whole facility is measured and reported in real-time. The data are compared with those obtained from detailed measurement and verification (M&V) processes. The discrepancy is less than 1.565%. Using measurements from the proposed sensor platform, the energy savings for the entire facility are quantified, with a resolution of ±1.2%. The VGS gives an 8.483% daily electricity saving for the building. Thus, the results show that the simple sensor platform proposed by this study is more widely applicable than the four complicated IPMVP alternatives and the VGS is an effective tool in reducing the carbon footprint of a building.

Autonomic behavior is subject to direct suggestion. We found that patients undergoing major operations benefit more from instruction than from information and reassurance. We compared the return of intestinal function after intra-abdominal operations in 2 groups of patients: the suggestion group received specific instructions for the early return of gastrointestinal motility, and the control group received an equal-length interview offering reassurance and nonspecific instructions. The suggestion group had a significantly shorter average time to the return of intestinal motility, 2.6 versus 4.1 days. Time to discharge was 6.5 versus 8.1 days. Covariates including duration of operation, amount of intraoperative bowel manipulation, and amount of postoperative narcotics were also examined using the statistical model analysis of covariance. An average savings of $1,200 per patient resulted from this simple 5-minute intervention. In summary, the use of specific physiologically active suggestions given preoperatively in a beleivable manner can reduce the morbidity associated with an intra-abdominal operation by reducing the duration of ileus.

Lassesson, Henric; Fedje, Karin Karlfeldt; Steenari, Britt-Marie

2014-08-01

Recovery of metals occurring in significant amounts in municipal solid waste incineration fly ash, such as copper, could offer several advantages: a decreased amount of potentially mobile metal compounds going to landfill, saving of natural resources and a monetary value. A combination of leaching and solvent extraction may constitute a feasible recovery path for metals from municipal solid waste incineration fly ash. However, it has been shown that the initial dissolution and leaching is a limiting step in such a recovery process. The work described in this article was focused on elucidating physical and chemical differences between two ash samples with the aim of explaining the differences in copper release from these samples in two leaching methods. The results showed that the chemical speciation is an important factor affecting the release of copper. The occurrence of copper as phosphate or silicate will hinder leaching, while sulphate and chloride will facilitate leaching. © The Author(s) 2014.

The environmental impacts of municipal solid waste management in Beijing City were evaluated using a life-cycle-based model, EASEWASTE, to take into account waste generation, collection, transportation, treatment/disposal technologies, and savings obtained by energy and material recovery. The current system, mainly involving the use of landfills, has manifested significant adverse environmental impacts caused by methane emissions from landfills and many other emissions from transfer stations. A short-term future scenario, where some of the landfills (which soon will reach their capacity because of rising amount of waste in Beijing City) are substituted by incinerators with energy recovery, would not result in significantmore » environmental improvement. This is primarily because of the low calorific value of mixed waste, and it is likely that the incinerators would require significant amounts of auxiliary fuels to support combustion of wet waste. As for the long-term future scenario, efficient source separation of food waste could result in significant environmental improvements, primarily because of increase in calorific value of remaining waste incinerated with energy recovery. Sensitivity analysis emphasized the importance of efficient source separation of food waste, as well as the electricity recovery in incinerators, in order to obtain an environmentally friendly waste management system in Beijing City.« less

Pattern Recognition for a Flight Dynamics Monte Carlo Simulation

Restrepo, Carolina; Hurtado, John E.

2011-01-01

The design, analysis, and verification and validation of a spacecraft relies heavily on Monte Carlo simulations. Modern computational techniques are able to generate large amounts of Monte Carlo data but flight dynamics engineers lack the time and resources to analyze it all. The growing amounts of data combined with the diminished available time of engineers motivates the need to automate the analysis process. Pattern recognition algorithms are an innovative way of analyzing flight dynamics data efficiently. They can search large data sets for specific patterns and highlight critical variables so analysts can focus their analysis efforts. This work combines a few tractable pattern recognition algorithms with basic flight dynamics concepts to build a practical analysis tool for Monte Carlo simulations. Current results show that this tool can quickly and automatically identify individual design parameters, and most importantly, specific combinations of parameters that should be avoided in order to prevent specific system failures. The current version uses a kernel density estimation algorithm and a sequential feature selection algorithm combined with a k-nearest neighbor classifier to find and rank important design parameters. This provides an increased level of confidence in the analysis and saves a significant amount of time.

Repayment policy for multiple loans

PubMed Central

2017-01-01

The Repayment Policy for Multiple Loans is about a given set of loans and a monthly incoming cash flow: what is the best way to allocate the monthly income to repay such loans? In this article, we close the almost 20-year-old open question about how to model the repayment policy for multiple loans problem together with its computational complexity. Thus, we propose a mixed integer linear programming model that establishes an optimal repayment schedule by minimizing the total amount of cash required to repay the loans. We prove that the most employed repayment strategies, such as the highest interest debt and the debt snowball methods, are not optimal. Experimental results on simulated cases based on real data show that our methodology obtains on average more than 4% of savings, that is, the debtor pays approximately 4% less to the bank or loaner, which is a considerable amount in finances. In certain cases, the debtor can save up to 40%. PMID:28430786

Patients with cancer often face financial hardships, including loss of productivity, high out-of-pocket (OOP) costs, depletion of savings, and bankruptcy. By providing financial guidance and assistance through specially trained navigators, hospitals and cancer care clinics may be able mitigate the financial burdens to patients and also minimize financial losses for the treating institutions. Financial navigators at 4 hospitals were trained through The NaVectis Group, an organization that provides training to healthcare staff to increase patient access to care and assist with OOP expenses. Data regarding financial assistance and hospital revenue were collected after instituting these programs. Amount and type of assistance (free medication, new insurance enrollment, premium/co-pay assistance) were determined annually for all qualifying patients at the participating hospitals. Of 11,186 new patients with cancer seen across the 4 participating hospitals between 2012 and 2016, 3572 (32%) qualified for financial assistance. They obtained $39 million in total financial assistance, averaging $3.5 million per year in the 11 years under observation. Patients saved an average of $33,265 annually on medication, $12,256 through enrollment in insurance plans, $35,294 with premium assistance, and $3076 with co-pay assistance. The 4 hospitals were able to avoid write-offs and save on charity care by an average of $2.1 million per year. Providing financial navigation training to staff at hospitals and cancer centers can significantly benefit patients through decreased OOP expenditures and also mitigate financial losses for healthcare institutions.

Conducting polymers: Synthesis and industrial applications

DOE Office of Scientific and Technical Information (OSTI.GOV)

Gottesfeld, S.

1997-04-01

The Conducting Polymer project funded by the AIM Program has developed new methods for the synthesis of conducting polymers and evaluated new industrial applications for these materials which will result in significant reductions in energy usage or industrial waste. The applications specifically addressed during FY 1996 included two ongoing efforts on membranes for gas separation and on electrochemical capacitors and a third new application: electrochemical reactors (ECRs) based on polymeric electrolytes. As a gas separation membrane, conducting polymers offer high selectivity and the potential to chemically or electrically adapt the membrane for specific gas combinations. Potential energy savings in themore » US for this application are estimated at 1 to 3 quads/yr. As an active material in electrochemical capacitors, electronically conducting polymers have the potential of storing large amounts of electric energy in low cost materials. Potential energy savings estimated at 1 quad/yr would result from introduction of electrochemical capacitors as energy storage devices in power trains of electric and hybrid vehicles, once such vehicles reach 20% of the total transportation market in the US. In the chlor-alkali industry, electrochemical reactors based on polymer electrolyte membranes consume around 1 % of the total electric power in the US. A new activity, started in FY 1996, is devoted to energy efficient ECRs. In the case of the chlor-alkali industry, energy savings as high as 50% seem possible with the novel ECR technology demonstrated by the author in 1996.« less

To estimate the willingness to pay (WTP) per quality-adjusted life year (QALY) value for life-saving treatments and to determine factors affecting the WTP per QALY value. A cross-sectional survey with multistage sampling and face-to-face interviews. General population in the southern part of Thailand. A total of 600 individuals were included in the study. Only 554 (92.3%) responses were usable for data analyses. Participants were asked for the maximum amount of WTP value for life-saving treatments by an open-ended question. EQ-5D-3L and visual analogue scale (VAS) were used to estimate additional QALY. The amount of WTP values varied from 0 to 720,000 Baht/year (approximately 32 Baht=US$1). The averages of additional QALY obtained from VAS and EQ-5D-3L were only slightly different (0.872 and 0.853, respectively). The averages of WTP per QALY obtained from VAS and EQ-5D-3L were 244,720 and 243,120 Baht/QALY, respectively. As compared to male participants, female participants were more likely to pay less for an additional QALY (p=0.007). In addition, participants with higher household incomes tended to have higher WTP per QALY values (p<0.001). Our study added another WTP per QALY value specifically for life-saving treatments, which would complement the current cost-effectiveness threshold used in Thailand and optimise patient access to innovative treatments or technologies.

Evaluation of Irrigation Water Use Efficiency and Water-saving in the Middle Oasis of Heihe River Basin Using a Distributed Agro-hydrological Model

NASA Astrophysics Data System (ADS)

Jiang, Y.; Huang, G., Sr.; Xu, X.; Huang, Q.; Huo, Z.

2015-12-01

Severe water scarcity and unreasonable allocation are threatening the eco-environment in the Heihe River basin (HRB), an arid and semi-arid watershed in Northwest China. The water use in the middle oasis accounts for about 70% of the total water use in the HRB, in which over 85% are consumed by irrigated agriculture. Thus the regional assessment and improvement of irrigation water use are quite essential for water-saving and eco-environmental sustainability. This paper applied a distributed agro-hydrological model (SWAP-EPIC) integrated with ArcGIS to investigate the irrigation water use efficiency (WUE) in the middle oasis. The detailed distributed data in 2012, including soil properties, irrigation schedules, crop pattern and calendar, were collected and used in the regional simulation. The spatial-temporal distribution of LAI and evapotranspiration (ETa) from remote sensing were used as observations to calibrate the model. Results showed that the simulation data was in a good agreement with the observation one. The relative WUE (i.e. divided by the mean value) ranged from 0.77 to 1.33 in different canal command areas. Large spatial variations of WUE were mainly caused by the non-uniform distribution of irrigation water. The present irrigation performance was poor, and only 50% of total irrigation amount was finally utilized through evapotranspiration in the whole district. While nearly 24% of the irrigation water were lost through field deep percolation and 26% were wasted in canal conveyance. Further analysis of water-saving scenarios was conducted through applying the improved irrigation schedule for each crop-soil unites and increasing the canal conveyance efficiency. Prediction showed that 15% of total irrigation amount can be saved without reduction of crop yield.

Incorporation of catalytic dehydrogenation into fischer-tropsch synthesis to significantly reduce carbon dioxide emissions

DOEpatents

Huffman, Gerald P.

2012-11-13

A new method of producing liquid transportation fuels from coal and other hydrocarbons that significantly reduces carbon dioxide emissions by combining Fischer-Tropsch synthesis with catalytic dehydrogenation is claimed. Catalytic dehydrogenation (CDH) of the gaseous products (C1-C4) of Fischer-Tropsch synthesis (FTS) can produce large quantities of hydrogen while converting the carbon to multi-walled carbon nanotubes (MWCNT). Incorporation of CDH into a FTS-CDH plant converting coal to liquid fuels can eliminate all or most of the CO.sub.2 emissions from the water-gas shift (WGS) reaction that is currently used to elevate the H.sub.2 level of coal-derived syngas for FTS. Additionally, the FTS-CDH process saves large amounts of water used by the WGS reaction and produces a valuable by-product, MWCNT.

A compilation of lunar and Mars exploration strategies utilizing indigenous propellants

NASA Technical Reports Server (NTRS)

Linne, Diane L.; Meyer, Michael L.

1992-01-01

The use of propellants manufactured from indigenous space materials has the potential to significantly reduce the amount of mass required to be launched from the Earth's surface. The extent of the leverage, however, along with the cost for developing the infrastructure necessary to support such a process, is unclear. Many mission analyses have been performed that have attempted to quantify the potential benefits of in situ propellant utilization. Because the planning of future space missions includes many unknowns, the presentation of any single study on the use of in situ propellants is often met with critics' claims of the inaccuracy of assumptions or omission of infrastructure requirements. The results of many such mission analyses are presented in one format. Each summarized mission analysis used different assumptions and baseline mission scenarios. The conclusion from the studies is that the use of in situ produced propellants will provide significant reductions in Earth launch requirements. This result is consistent among all of the analyses regardless of the assumptions used to obtain the quantitative results. The determination of the best propellant combination and the amount of savings will become clearer and more apparent as the technology work progresses.

Buildings account for about 40 percent of the total energy consumption in the U.S. and emit approximately one third of greenhouse gas emissions. But they also offer tremendous potential for achieving significant greenhouse gas reductions with the right savings strategies. With an increasing amount of data from buildings and advanced computational and analytical abilities, buildings can be made “smart” to optimize energy consumption and occupant comfort. Smart buildings are often characterized as having a high degree of data and system integration, connectivity and control, as well as the advanced use of data analytics. These “smarts” can enable up to 10–20%more » savings in a building, and help ensure that they persist over time. In 2009, Microsoft Corporation launched the Energy-Smart Buildings (ESB) program with a vision to improve building operations services, security and accessibility in services, and new tenant applications and services that improve productivity and optimize energy use. The ESB program focused on fault diagnostics, advanced analytics and new organizational processes and practices to support their operational integration. In addition to the ESB program, Microsoft undertook capital improvement projects that made effective use of a utility incentive program and lab consolidations over the same duration. The ESB program began with a pilot at Microsoft's Puget Sound campus that identified significant savings of up to 6–10% in the 13 pilot buildings. The success of the pilot led to a global deployment of the program. Between 2009 and 2015, there was a 23.7% reduction in annual electricity consumption (kWh) at the Puget Sound campus with 18.5% of that resulting from the ESB and lab consolidations. This article provides the results of research conducted to assess the best-practice strategies that Microsoft implemented to achieve these savings, including the fault diagnostic routines that are the foundation of the ESB program and organizational change management practices. It also presents the process that was adopted to scale the ESB program globally. We conclude with recommendations for how these successes can be generalized and replicated by other corporate enterprises.« less

Greenhouse gas emissions of an agro-biogas energy system: Estimation under the Renewable Energy Directive.

PubMed

Rana, Roberto; Ingrao, Carlo; Lombardi, Mariarosaria; Tricase, Caterina

2016-04-15

Agro-biogas from energy crops and by-products is a renewable energy carrier that can potentially contribute to climate change mitigation. In this context, application of the methodology defined by the Renewable Energy Directive 2009/28/EC (RED) was performed in order to estimate the 100-year Global Warming Potential (GWP100) associated with an agro-biogas supply chain (SC) in Southern Italy. Doing so enabled calculation of Greenhouse Gas (GHG) emission saving in order to verify if it is at least equal to 35% compared to the fossil fuel reference system, as specified by the RED. For the assessment, an attributional Life Cycle Assessment (LCA) approach (International Organization for Standardization (ISO), 2006a,b) was integrated with the RED methodology applied following the guidelines reported in COM(2010)11 and updated by SWD(2014)259 and Report EUR 27215 EN (2015). Moreover, primary data were collected with secondary data extrapolated from the Ecoinvent database system. Results showed that the GWP100 associated with electricity production through the biogas plant investigated was equal to 111.58gCO2eqMJe(-1) and so a 40.01% GHG-emission saving was recorded compared to the RED reference. The highest contribution comes from biomass production and, in particular, from crop cultivation due to production of ammonium nitrate in the overall amount used for crop cultivation. Based upon the findings of the study, the GHG saving calculated slightly exceeds the related minimum proposed by the RED: therefore, improvements are needed anyway. In particular, the authors documented that through replacement of ammonium nitrate with urea the GHG-emission saving would increase to almost 68%, thus largely satisfying the RED limit. In addition, the study highlighted that conservation practices, such as NT, can significantly enable reduction of the GHG-emissions coming from agricultural activities. Therefore, those practices should be increasingly adopted for cultivation of energy crops, because the latter significantly contribute to biogas production yield enhancement.

RESULTS FROM THE U.S. DOE 2006 SAVE ENERGY NOW ASSESSMENT INITIATIVE: DOE's Partnership with U.S. Industry to Reduce Energy Consumption, Energy Costs, and Carbon Dioxide Emissions

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wright, Anthony L; Martin, Michaela A; Gemmer, Bob

In the wake of Hurricane Katrina and other severe storms in 2005, natural gas supplies were restricted, prices rose, and industry sought ways to reduce its natural gas use and costs. In October 2005, U.S. Department of Energy (DOE) Energy Secretary Bodman launched his Easy Ways to Save Energy campaign with a promise to provide energy assessments to 200 of the largest U.S. manufacturing plants. A major thrust of the campaign was to ensure that the nation's natural gas supplies would be adequate for all Americans, especially during home heating seasons. In a presentation to the National Press Club onmore » October 3, 2005, Secretary Bodman said: 'America's businesses, factories, and manufacturing facilities use massive amounts of energy. To help them during this period of tightening supply and rising costs, our Department is sending teams of qualified efficiency experts to 200 of the nation's most energy-intensive factories. Our Energy Saving Teams will work with on-site managers on ways to conserve energy and use it more efficiently.' DOE's Industrial Technologies Program (ITP) responded to the Secretary's campaign with its Save Energy Now initiative, featuring a new and highly cost-effective form of energy assessments. The approach for these assessments drew heavily on the existing resources of ITP's Technology Delivery component. Over the years, ITP-Technology Delivery had worked with industry partners to assemble a suite of respected software decision tools, proven assessment protocols, training curricula, certified experts, and strong partnerships for deployment. Because of the program's earlier activities and the resources that had been developed, ITP was prepared to respond swiftly and effectively to the sudden need to promote improved industrial energy efficiency. Because of anticipated supply issues in the natural gas sector, the Save Energy Now initiative strategically focused on natural gas savings and targeted the nation's largest manufacturing plants--those that consume a total of 1 trillion British thermal units (Btu) or more annually. The approximately 6800 U.S. facilities that fall into this category collectively account for about 53% of all energy consumed by industry in the United States. The 2006 Save Energy Now energy assessments departed from earlier DOE plant assessments by concentrating solely on steam and process heating systems, which are estimated to account for approximately 74% of all natural gas use for manufacturing. The assessments also integrated a strong training component designed to teach industrial plant personnel how to use DOE's steam or process heating opportunity assessment software tools. This approach had the advantages of promoting strong buy-in of plant personnel for the assessment and its outcomes and preparing them better to independently replicate the assessment process at the company's other facilities. The Save Energy Now initiative also included provisions to help plants that applied for but did not qualify for assessments (based on the 1 trillion Btu criterion). Services offered to these plants included (1) an assessment by one of DOE's 26 university-based Industrial Assessment Centers (IACs), (2) a telephone consultation with a systems expert at the DOE's Energy Efficiency and Renewable Energy Information Center, or (3) other technical materials and services available through ITP (e.g., the Save Energy Now CD). By the end of 2006, DOE had completed all 200 of the promised assessments, identifying potential natural gas savings of more than 50 trillion Btu and energy cost savings of about $500 million. These savings, if fully implemented, could reduce CO2 emissions by 4.04 million metric tons annually. These results, along with the fact that a large percentage of U.S. energy is used by a relatively small number of very large plants, clearly suggest that assessments are an expedient and cost-effective way to significantly affect large amounts of energy use. Building on the success of the 2006 initiative, ITP has expanded the effort in 2007 with the goal of conducting 250 more assessments in large U.S. industrial plants. The 2007 assessments are addressing not only steam and process heating, but also pumping, compressed air, and fan systems. The full report reviews the tools and resources developed by the DOE ITP program before 2006, which are the foundation and catalyst for the Save Energy Now assessment efforts. The report describes the process by which industrial plants applied to obtain assessments in 2006 and the overall process and philosophy of conducting assessments. A comprehensive review of the results from the 2006 assessments is presented, along with a summary of key accomplishments and findings.« less

Health savings accounts and health reimbursement arrangements: assets, account balances, and rollovers, 2006-2010.

2011-01-01

ASSET LEVELS GROWING: In 2010, there was $7.7 billion in health savings accounts (HSAs) and health reimbursement arrangements (HRAs), spread across 5.7 million accounts. This is up from 2006, when there were 1.2 million accounts with $835.4 million in assets, and 2009, when 5 million accounts held $7.1 billion in assets. AFTER LEVELING OFF, AVERAGE ACCOUNT BALANCE DROPS SLIGHTLY: Increases in average account balances leveled off in 2008 and 2009, and fell slightly in 2010. In 2006, account balances averaged $696. They increased to $1,320 in 2007, a 90 percent increase. Account balances averaged $1,356 in 2008 and $1,419 in 2009, 3 percent and 5 percent increases, respectively. In 2010, average account balances fell to $1,355, down 4.5 percent from the previous year. AVERAGE ROLLOVER DECLINES, WHILE TOTAL ROLLOVERS INCREASE: Despite a decline in the average rollover amount in 2010, total assets being rolled over have been increasing. $4.2 billion was rolled over in 2010, up from $4 billion in 2009. The average rollover increased from $592 in 2006 to $1,295 in 2009, and fell to $1,029 in 2010. The percentage of individuals without a rollover decreased from 23 percent in 2006 to 10 percent in 2009 and increased slightly to 13 percent in 2010. HEALTHY BEHAVIOR MEANS HIGHER ACCOUNT BALANCES AND HIGHER ROLLOVERS: Individuals who exercised, those who did not smoke, and those who were not obese had higher account balances and higher rollovers than those with less healthy behaviors. It was also found that individuals who used cost or quality information had higher account balances and higher rollovers compared with those who did not use such information. However, no relationship was found between either account balance or rollover amounts and various cost-conscious behaviors such as checking pricing before getting services or asking for generic drugs instead of brand names, among other things. DIFFERENCES IN ACCOUNT BALANCES: Men have higher account balances than women, older individuals have higher account balances than younger ones, account balances increase with household income, and education has a significant impact on account balances independent of income and other variables. DIFFERENCES IN ROLLOVER AMOUNTS: Men rolled over more money than women, and older individuals had higher rollover amounts than younger individuals. Rollover amounts increase with household income and education, and individuals with single coverage rolled over a higher amount than those with family coverage.

With the move to the doctor of physical therapy (DPT) degree and increasing tuition costs, there is concern about financing entry-level education. The purposes of this study were to identify how students finance their DPT education and to describe the financial impact after graduation. A written survey was used to collect data on financing DPT education, student debt, and the financial impact on graduates. There were 92 subjects who had graduated from one program. Frequencies as well as nonparametric statistics using cross-tabulations and chi-squared statistics were calculated. The response rate was 55%. Of the respondents, 86% had student loans, 66% worked during school, 57% received some family assistance, and 21% had some scholarship support. The amount of monthly loan repayment was not statistically related to the ability to save for a house, the ability to obtain a loan for a house or car, or the decision to have children. Saving for the future (p = 0.016) and lifestyle choices (p = 0.035) were related to the amount of monthly loan repayment. Major sources of funding were student loans, employment income, and/or family assistance. Respondent's ability to save for the future and lifestyle choices were negatively impacted when loan debt increased. Physical therapist education programs should consider offering debt planning and counseling.

Staging Airliner Service

NASA Technical Reports Server (NTRS)

Hahn, Andrew S.

2007-01-01

There is a general consensus building that historically high fuel prices and greater public awareness of the emissions that result from burning fuel are going to be long-term concerns for those who design, build, and operate airliners. The possibility of saving both fuel and reducing emissions has rekindled interest in breaking very long-range airline flights into multiple stages or even adopting in-flight refueling. It is likely that staging will result in lower fuel burn, and recent published reports have suggested that the savings are substantial, particularly if the airliner is designed from the outset for this kind of operation. Given that staging runs against the design and operation historical trend, this result begs for further attention. This paper will examine the staging question, examining both analytic and numeric performance estimation methodologies to quantify the likely amount of fuel savings that can be expected and the resulting design impacts on the airliner.

A Study on the Saving Method of Plate Jigs in Hull Block Butt Welding

Ko, Dae-Eun

2017-11-01

A large amount of plate jigs is used for alignment of welding line and control of welding deformations in hull block assembly stage. Besides material cost, the huge working man-hours required for working process of plate jigs is one of the obstacles in productivity growth of shipyard. In this study, analysis method was proposed to simulate the welding deformations of block butt joint with plate jigs setting. Using the proposed analysis method, an example simulation was performed for actual panel block joint to investigate the saving method of plate jigs. Results show that it is possible to achieve two objectives of quality accuracy of the hull block and saving the plate jig usage at the same time by deploying the plate jigs at the right places. And the proposed analysis method can be used in establishing guidelines for the proper use of plate jigs in block assembly stage.

Dryer cuts fuel usage by equivalent of 6-million scf/yr

List, K.H.; Powers, J.

Drying is an integral part of the production of ZnO pellets, a specific requirement for producing a uniform end product. The dryer has to be able to cure the product for a finite period at temperatures up to 500/sup 0/C in the same unit. Substantial savings have been realized because the dryer has enabled the user to optimize operating conditions. Continuous on-stream operations requiring minimum operator attendance, automatic controls, simplicity of design contruction, and the unit's ability to use waste heat also contribute to these savings. Gas exhausted from a nearby kiln provides the total heat requirement for the dryer.more » Positive delivery of the hot flue gas is assured by a blower and automatically controlled dampers. Annual fuel savings based on the use of waste heat, amounts to an equiv of 6 million scf of natural gas. 1 figure.« less

2012-10-01

Several high-temperature liquid chromatography (HTLC) and subcritical water chromatography (SBWC) methods have been successfully developed in this study for separation and analysis of preservatives contained in Olay skincare creams. Efficient separation and quantitative analysis of preservatives have been achieved on four commercially available ZirChrom and Waters XBridge columns at temperatures ranging from 100 to 200°C. The quantification results obtained by both HTLC and SBWC methods developed for preservatives analysis are accurate and reproducible. A large number of replicate HTLC and SBWC runs also indicate no significant system building-up or interference for skincare cream analysis. Compared with traditional HPLC separation carried out at ambient temperature, the HTLC methods can save up to 90% methanol required in the HPLC mobile phase. However, the SBWC methods developed in this project completely eliminated the use of toxic organic solvents required in the HPLC mobile phase, thus saving a significant amount of money and making the environment greener.

Microscopic examination of feces is a standard laboratory method for diagnosing gastrointestinal parasite infections. In North America, the ovum and parasite (O&P) examination is typically performed using stool that is chemically fixed in polyvinyl alcohol (PVA) and formalin, after which the stool is concentrated by filtration to enhance sensitivity. Mini Parasep solvent-free (SF) tubes allow collection and concentration within a single collection vial. The goal of the study was to determine whether consolidated processing and concentration with the Parasep tubes using an alcohol-based fixative (Alcorfix) provide O&P examinations equivalent to or better than those done by processing of PVA-formalin-fixed stool using a SpinCon concentration device. Parasep tubes revealed filtration performance equivalent to that of the SpinCon concentration device using PVA-formalin-fixed stool containing protozoa. Specimens cocollected in Parasep tubes containing PVA-formalin and Alcorfix revealed comparable morphology and staining for various protozoa. Alcorfix effectively fixed live Cryptosporidium and microsporidia such that morphology and staining were conserved for modified acid-fast and modified trichrome stains. A work flow analysis revealed significant time savings for batches of 10 or 30 O&P specimens in tubes with Alcorfix compared to the amount of time that it took to analyze the same number of specimens in tubes with PVA-formalin. The direct hands-on time savings with Mini Parasep tubes were 17 min and 41 s and 32 min and 1 s for batches of 10 and 30 specimens, respectively. Parasep tubes containing Alcorfix provide significant work flow advantages to laboratories that process medium to high volumes of O&P specimens by streamlining processing and converting to a single tube. These improvements in work flow, reduction of the amount of formalin used in the laboratory, and equivalent microscopy results are attractive advancements in O&P testing for North American diagnostic parasitology laboratories.

Jammar, R.J.

When properly designed, planning and scheduling can actually add millions of dollars per year to the bottom line. Planning and scheduling is a continuum of decisions starting with crude selection and ending with establishing short-term targets for crude processing and blending. It also includes maintaining optimization and operation simulation models. It is thought that conservatively, a refinery may save from $5 million to $10 million a year if it pays more attention to the processes behind proper planning and scheduling. Of course, the amount of savings can reach staggering proportions for companies now at the bottom of the Solomon Associatesmore » Inc. refinery performance ranking.« less

Insurers’ Negotiating Leverage and the External Effects of Medicare Part D*

PubMed Central

Lakdawalla, Darius; Yin, Wesley

2014-01-01

By influencing the size and bargaining power of private insurers, public subsidization of private health insurance may project effects beyond the subsidized population. We test for such spillovers by analyzing how increases in insurer size resulting from the implementation of Medicare Part D affected drug prices negotiated in the non-Medicare commercial market. On average, Part D lowered prices for commercial enrollees by 3.7%. The external commercial market savings amount to $1.5 billion per year, which, if passed to consumers, approximates the internal cost-savings of newly-insured subsidized beneficiaries. If retained by insurers, it corresponds to a 5% average increase in profitability. PMID:25937676

Cost-effective control of nitrogen loadings in Long Island Sound

Bennett, Lynne L.; Thorpe, Steven G.; Guse, A. Joseph

2000-12-01

Long Island Sound is plagued by conditions of severe hypoxia (low levels of dissolved oxygen) during the summer months because of the existence of excessive amounts of nitrogen. A new proposal that would allow sewage treatment plants to buy or sell nitrogen discharge credits is currently being evaluated by the states of Connecticut and New York. Existing theory suggests that a trading program for nitrogen emissions would be a cost-effective means of addressing the problem. We estimate the costs associated with several trading scenarios and find that the potential for cost savings is substantial and that cost savings rise as the scope of trading expands.

Not Available

This report analyzes the potential economic impacts of the Emergency Advertising Lighting Restrictions Plan. The on-premise signs located within the confines of a business and off-premise located outside the confines of a business are affected. Illuminated signs essential to direct customers to an open business by identifying it and/or to inform customers of a product or service supplied by the open business are not restricted. The economic impact of implementing this plan is evaluated by first estimating the amount of petroleum saved by the lighting restrictions and to evaluate the economic impacts that would result. The amount of oil thatmore » could be diverted to other uses by implementation of this plan is estimated in Chapter 2, and amounts to about 4,000 barrels per day (the period analyzed is the fourth quarter of 1980 through the third quarter of 1981). Redistribution of petroleum saved by this measure is expected to result in small increases in GNP, personal consumption, and employment. The effects on inflation are negligible. Economic impacts for the businesses are evaluated in Chapter 3. Costs of implementing the measure are estimated to be about $3.1 million, including the cost of reimbursing the states for functions delegated to them. (MCW)« less

Accountable care organizations (ACOs) have diverse contracting arrangements and have displayed wide variation in their performance. Using data from national surveys of 399 ACOs, we examined differences between the 228 commercial ACOs (those with commercial payer contracts) and the 171 noncommercial ACOs (those with only public contracts, such as with Medicare or Medicaid). Commercial ACOs were significantly larger and more integrated with hospitals, and had lower benchmark expenditures and higher quality scores, compared to noncommercial ACOs. Among all of the ACOs, there was low uptake of quality and efficiency activities. However, commercial ACOs reported more use of disease monitoring tools, patient satisfaction data, and quality improvement methods than did noncommercial ACOs. Few ACOs reported having high-level performance monitoring capabilities. About two-thirds of the ACOs had established processes for distributing any savings accrued, and these ACOs allocated approximately the same amount of savings to the ACOs themselves, participating member organizations, and physicians. Our findings demonstrate that ACO delivery systems remain at a nascent stage. Structural differences between commercial and noncommercial ACOs are important factors to consider as public policy efforts continue to evolve.

Research Objective To evaluate the design, development, and implementation of Florida's Medicaid provider service network (PSN) demonstration, and the implications of that demonstration for subsequent Medicaid Reform in Florida. Data Sources, Data Collection Organizational analyses were based on archival and enrollment data obtained from Florida's Medicaid program and the South Florida Community Care Network, as well as key informant interviews. Closely related fiscal analyses utilized Medicaid claims data from March 1999 through October 2001 extracted from the Florida Medicaid Management Information System. Study Design The organizational analyses reported here were based on a structured case study research design. Principal Findings Almost every aspect of the development of the new organizational form (PSN) took longer and was more difficult than anticipated. Prior organizational experience with insurance functions proved to be an asset. While fiscal analyses indicated that the program saved the state of Florida a significant amount of money, tracking the precise origin of the savings proved to be challenging. Conclusions By most standards, the PSN program was observed to meet its stated objectives. Based in part on this conclusion, the state chose to extend the use of PSNs within its 2006 Medicaid Reform initiative. PMID:18199192

Analysis of optimal design of low temperature economizer

NASA Astrophysics Data System (ADS)

Song, J. H.; Wang, S.

2017-11-01

This paper has studied the Off-design characteristic of low temperature economizer system based on thermodynamics analysis. Based on the data from one 1000 MW coal-fired unit, two modes of operation are contrasted and analyzed. One is to fix exhaust gas temperature and the other one is to take into account both of the average temperature difference and the exhaust gas temperature. Meanwhile, the cause of energy saving effect change is explored. Result shows that: in mode 1, the amount of decrease in coal consumption reduces from 1.11 g/kWh (under full load) to 0.54 g/kWh (under half load), and in mode 2, when the load decreases from 90% to 50%, the decrease in coal consumption reduces from 1.29 g/kWh to 0.84 g/kWh. From the result, under high load, the energy saving effect is superior, and under lower work load, energy saving effect declines rapidly when load is reduced. When load changes, the temperature difference of heat transfer, gas flow, the flue gas heat rejection and the waste heat recovery change. The energy saving effect corresponding changes result in that the energy saving effect under high load is superior and more stable. However, rational adjustment to the temperature of outlet gas can alleviate the decline of the energy saving effect under low load. The result provides theoretical analysis data for the optimal design and operation of low temperature economizer system of power plant.

Washington State CARE Project: downstream cost changes associated with the provision of cognitive services by pharmacists.

1999-01-01

To determine the changes in drug costs associated with drug therapy changes resulting from pharmacists' cognitive services (CS) provided to Medicaid recipients during a 1-year period following the documented CS. A study-control group analysis of documented pharmacists' CS interventions linked to Medicaid prescription claims. Each CS resulting in a drug therapy change was linked to an index prescription claim and all refills for the same drug within 365 days. The drug cost change associated with the CS was calculated as the difference between the estimated cost of the prescription as originally written less the actual cost to Medicaid for the stream of refills dispensed. Pharmacies serving ambulatory Medicaid patients in the state of Washington, excluding staff-model health maintenance organization pharmacies and pharmacies predominantly serving long-term care residents. Approximately 200 community pharmacies participating in the Washington State Cognitive Activities and Reimbursement Effectiveness (CARE) Project. Pharmacies were randomly assigned to a group that was paid a fee for each CS provided or a group that was not paid. Payment for CS. Downstream drug costs associated with CS resulting in a drug therapy change. CS resulting in drug therapy changes accounted for 5,417 out of 20,240 (27%) documented CS in the CARE Project. Of the 2,002 CS records analyzed in this study, 76% indicated a change in the prescribed drug or drug regimen, 9% indicated that a drug was added, 5% indicated that a current drug was discontinued, and 10% indicated that an originally prescribed drug was never dispensed. Only 9% involved generic substitution; all other changes would have necessitated prior prescriber approval. Overall, CS resulting in a drug therapy change generated a mean drug cost savings of $13.05 per CS intervention. There were no significant differences in average savings per intervention between the paid and nonpaid groups. For all result categories except "add drug therapy," the extrapolated cost savings in the paid group exceeded the savings estimated from the nonpaid group, sometimes by a considerable amount. At the payment rate used in this study, paying for CS that result in a drug therapy change (except add drug therapy) is estimated to save an additional $10 per 1,000 prescriptions dispensed. Those CS that result in addition of drug therapy are estimated to add an incremental cost of about $13 per 1,000 prescriptions. A sensitivity analysis revealed that a higher intervention rate would lead to a higher potential savings. This finding suggests that efforts to encourage CS interventions may lead to greater savings.

Semuloparin is a novel ultra-low-molecular-weight heparin under development for venous thromboembolism (VTE) prevention in patients at increased risk, such as surgical and cancer patients. Three Phase III studies compared semuloparin and enoxaparin after major orthopedic surgery: elective knee replacement (SAVE-KNEE), elective hip replacement (SAVE-HIP1) and hip fracture surgery (SAVE-HIP2). All studies were multinational, randomized and double-blind. Semuloparin and enoxaparin were administered for 7-10 days after surgery. Mandatory bilateral venography was to be performed between days 7 and 11. The primary efficacy endpoint was a composite of any deep vein thrombosis, non-fatal pulmonary embolism or all-cause death. Safety outcomes included major bleeding, clinically relevant non-major (CRNM) bleeding, and any clinically relevant bleeding (major bleeding plus CRNM). In total, 1150, 2326 and 1003 patients were randomized in SAVE-KNEE, SAVE-HIP1 and SAVE-HIP2, respectively. In all studies, the incidences of the primary efficacy endpoint were numerically lower in the semuloparin group vs. the enoxaparin group, but the difference was statistically significant only in SAVE-HIP1. In SAVE-HIP1, clinically relevant bleeding and major bleeding were significantly lower in the semuloparin vs. the enoxaparin group. In SAVE-KNEE and SAVE-HIP2, clinically relevant bleeding tended to be higher in the semuloparin group, but rates of major bleeding were similar in the two groups. Other safety parameters were generally similar between treatment groups. Semuloparin was superior to enoxaparin for VTE prevention after hip replacement surgery, but failed to demonstrate superiority after knee replacement surgery and hip fracture surgery. Semuloparin and enoxaparin exhibited generally similar safety profiles. © 2012 International Society on Thrombosis and Haemostasis.

2017-11-01

While aperiodically triggered network control systems save a considerable amount of communication bandwidth, they also pose challenges such as coupling between control and event-condition design, optimisation of the available resources such as control, communication and computation power, and time-delays due to computation and communication network. With this motivation, the paper presents separate designs of control and event-triggering mechanism, thus simplifying the overall analysis, asynchronous linear quadratic Gaussian controller which tackles delays and aperiodic nature of transmissions, and a novel event mechanism which compares the cost of the aperiodic system against a reference periodic implementation. The proposed scheme is simulated on a linearised wind turbine model for pitch angle control and the results show significant improvement against the periodic counterpart.

Saving can save from death anxiety: mortality salience and financial decision-making.

Four studies tested the idea that saving money can buffer death anxiety and constitute a more effective buffer than spending money. Saving can relieve future-related anxiety and provide people with a sense of control over their fate, thereby rendering death thoughts less threatening. Study 1 found that participants primed with both saving and spending reported lower death fear than controls. Saving primes, however, were associated with significantly lower death fear than spending primes. Study 2 demonstrated that mortality primes increase the attractiveness of more frugal behaviors in save-or-spend dilemmas. Studies 3 and 4 found, in two different cultures (Polish and American), that the activation of death thoughts prompts people to allocate money to saving as opposed to spending. Overall, these studies provided evidence that saving protects from existential anxiety, and probably more so than spending.

Nitrate leaching and the resulting groundwater contamination from intensive cereal production has become a major concern for long-term farmland efficiency and environmental sustainability in northern China. The aim of this study was to evaluate a water-saving super-absorbent polymer (SAP) for minimising NO(3)(-) leaching from soil and optimising corn growth and yield. Thirty-six undisturbed soil lysimeters were installed in a field lysimeter facility in drought-affected northern China to study the growth and yield characteristics of summer corn (Zea mays L.) as well as the amount of NO(3)-leaching losses under different fertiliser (standard, medium or 75% and low, or 50% of conventional fertilisation rate) and SAP (control, 0; level-1, 15 kg ha(-1) and level-2, 30 kg ha(-1)) treatments. Corn yield fell by 19.7% under medium and 37.7% under low fertilisation; the application of SAP increased yield significantly by 44.4% on level-1 and 80.3% on level-2. Similarly, plant height, leaf area, number of grains as well as protein, soluble sugar and starch contents in the grain also increased with SAP treatment. Application of SAP at 30 kg ha(-1) plus half of conventional fertilisation can reduce maximum (64.1%) nitrate leaching losses from soil. Application of SAP at 30 kg ha(-1) plus only half the amount of conventional fertiliser rate (150 kg urea, and 50 kg each of superphosphate and potassium sulfate) would be a more appropriate practice both for minimising nitrate leaching and sustainable corn production under the arid and semiarid conditions of northern China.

Nonprofit hospitals are expected to serve their communities as charitable organizations in exchange for the tax exemption benefits they receive. With the passage into law of the Affordable Care Act, additional guidelines were generated in 2010 to ensure nonprofit hospitals are compliant. Nonetheless, the debate continues on whether nonprofit hospitals provide adequate charity care to their patient population. In this study, charity care provided by 29 Washington State nonprofit urban hospitals was examined for 2011 using financial data from the Washington State Department of Health. Charity care levels were compared to both income tax savings and gross revenues to generate two financial ratios that were analyzed according to hospital bed size and nonprofit ownership type. For the first ratio, 97% of the hospitals (28 of 29) were providing charity care in greater amounts than the tax savings they accrued. The average ratio value using total charity care and total income tax savings of all the hospitals in the study was 6.10, and the median value was 3.46. The nonparametric Kruskal-Wallis test results by bed size and nonprofit ownership type indicate that ownership type has a significant effect on charity care to gross revenue ratios (p = .020). Our analysis indicates that church-owned hospitals had higher ratios of charity care to gross revenues than did the other two ownership types--government and voluntary--in this sample. Policy implications are offered and further studies are recommended to analyze appropriate levels of charity care in nonprofit hospitals given new requirements for maintaining a hospital's tax-exempt status.

Ice-based thermal energy storage (TES) systems can shift peak cooling demand and reduce operational energy costs (with time-of-use rates) in commercial buildings. The accurate prediction of the cooling load, and the optimal control strategy for managing the charging and discharging of a TES system, are two critical elements to improving system performance and achieving energy cost savings. This study utilizes data-driven analytics and modeling to holistically understand the operation of an ice–based TES system in a shopping mall, calculating the system’s performance using actual measured data from installed meters and sensors. Results show that there is significant savings potential whenmore » the current operating strategy is improved by appropriately scheduling the operation of each piece of equipment of the TES system, as well as by determining the amount of charging and discharging for each day. A novel optimal control strategy, determined by an optimization algorithm of Sequential Quadratic Programming, was developed to minimize the TES system’s operating costs. Three heuristic strategies were also investigated for comparison with our proposed strategy, and the results demonstrate the superiority of our method to the heuristic strategies in terms of total energy cost savings. Specifically, the optimal strategy yields energy costs of up to 11.3% per day and 9.3% per month compared with current operational strategies. A one-day-ahead hourly load prediction was also developed using machine learning algorithms, which facilitates the adoption of the developed data analytics and optimization of the control strategy in a real TES system operation.« less

This is truly the era of 'faster-better-cheaper' at the National Aeronautics and Space Administration/Jet Propulsion Laboratory (NASA/JPL). To continue JPL's primary mission of building and operating interplanetary spacecraft, all possible avenues are being explored in the search for better value for each dollar spent. A significant cost factor in any mission is the amount of manpower required to receive, decode, decommutate, and distribute spacecraft engineering and experiment data. The replacement of the many mission-unique data systems with the single Advanced Multimission Operations System (AMMOS) has already allowed for some manpower reduction. Now, we find that further economies are made possible by drastically reducing the number of human interventions required to perform the setup, data saving, station handover, processed data loading, and tear down activities that are associated with each spacecraft tracking pass. We have recently adapted three public domain tools to the AMMOS system which allow common elements to be scheduled and initialized without the normal human intervention. This is accomplished with a stored weekly event schedule. The manual entries and specialized scripts which had to be provided just prior to and during a pass are now triggered by the schedule to perform the functions unique to the upcoming pass. This combination of public domain software and the AMMOS system has been run in parallel with the flight operation in an online testing phase for six months. With this methodology, a savings of 11 man-years per year is projected with no increase in data loss or project risk. There are even greater savings to be gained as we learn other uses for this configuration.

All North Carolina prescription claims from Medicaid enrollees who filled a prescription for at least one of six medication categories during fiscal years 1999 and 2000 were included. The six categories were angiotensin-converting-enzyme inhibitors, antiulcers, antipsychotics, nonsteroidal antiinflammatory drugs, selective serotonin-reuptake inhibitors, and sulfonylureas. The dollar value of the medication wasted, the amount of medication wastage diverted after a change to a shorter prescription length, and the total costs incurred by the increases in prescription refills were calculated. For each therapeutic category, 255,000-783,000 prescription drug claims were analyzed. No valid drug claims were excluded for any reason. Although 5-14% of total drug wastage, attributed to switches of drug therapy, could be saved by dispensing a 34-day supply, this saving could not make up for a larger increase in dispensing costs, as consumers would fill prescriptions more often. In addition, reducing the amount of drug dispensed each time may be costly to consumers through increased transportation and other expenses. Simulated calculation showed that the cost of drug therapy to North Carolina's Medicaid program would probably increase if 34-day rather than 100-day supplies of medications are dispensed to patients.

A case study in electricity regulation: Theory, evidence, and policy

NASA Astrophysics Data System (ADS)

Luk, Stephen Kai Ming

This research provides a thorough empirical analysis of the problem of excess capacity found in the electricity supply industry in Hong Kong. I utilize a cost-function based temporary equilibrium framework to investigate empirically whether the current regulatory scheme encourages the two utilities to overinvest in capital, and how much consumers would have saved if the underutilized capacity is eliminated. The research is divided into two main parts. The first section attempts to find any evidence of over-investment in capital. As a point of departure from traditional analysis, I treat physical capital as quasi-fixed, which implies a restricted cost function to represent the firm's short-run cost structure. Under such specification, the firm minimizes the cost of employing variable factor inputs subject to predetermined levels of quasi-fixed factors. Using a transcendental logarithmic restricted cost function, I estimate the cost-side equivalent of marginal product of capital, or commonly referred to as "shadow values" of capital. The estimation results suggest that the two electric utilities consistently over-invest in generation capacity. The second part of this research focuses on the economies of capital utilization, and the estimation of distortion cost in capital investment. Again, I utilize a translog specification of the cost function to estimate the actual cost of the excess capacity, and to find out how much consumers could have saved if the underutilized generation capacity were brought closer to the international standard. Estimation results indicate that an increase in the utilization rate can significantly reduce the costs of both utilities. And if the current excess capacity were reduced to the international standard, the combined savings in costs for both firms will reach 4.4 billion. This amount of savings, if redistributed to all consumers evenly, will translate into a 650 rebate per capita. Finally, two policy recommendations: a more stringent policy towards capacity expansion and the creation of a reimbursement program, are discussed.

The objective of this article was to conduct a cost analysis comparing the costs of a supportive housing intervention to inpatient care for clients with severe mental illness who were designated alternative-level care while inpatient at the Centre for Addiction and Mental Health in Toronto. The intervention, called the High Support Housing Initiative, was implemented in 2013 through a collaboration between 15 agencies in the Toronto area. The perspective of this cost analysis was that of the Ontario Ministry of Health and Long-Term Care. We compared the cost of inpatient mental health care to high-support housing. Cost data were derived from a variety of sources, including health administrative data, expenditures reported by housing providers, and document analysis. The High Support Housing Initiative was cost saving relative to inpatient care. The average cost savings per diem were between $140 and $160. This amounts to an annual cost savings of approximately $51,000 to $58,000. When tested through sensitivity analysis, the intervention remained cost saving in most scenarios; however, the result was highly sensitive to health system costs for clients of the High Support Housing Initiative program. This study suggests the High Support Housing Initiative is potentially cost saving relative to inpatient hospitalization at the Centre for Addiction and Mental Health.

Potential Energy Cost Savings from Increased Commercial Energy Code Compliance

Rosenberg, Michael I.; Hart, Philip R.; Athalye, Rahul A.

2016-08-22

An important question for commercial energy code compliance is: “How much energy cost savings can better compliance achieve?” This question is in sharp contrast to prior efforts that used a checklist of code requirements, each of which was graded pass or fail. Percent compliance for any given building was simply the percent of individual requirements that passed. A field investigation method is being developed that goes beyond the binary approach to determine how much energy cost savings is not realized. Prototype building simulations were used to estimate the energy cost impact of varying levels of non-compliance for newly constructed officemore » buildings in climate zone 4C. Field data collected from actual buildings on specific conditions relative to code requirements was then applied to the simulation results to find the potential lost energy savings for a single building or for a sample of buildings. This new methodology was tested on nine office buildings in climate zone 4C. The amount of additional energy cost savings they could have achieved had they complied fully with the 2012 International Energy Conservation Code is determined. This paper will present the results of the test, lessons learned, describe follow-on research that is needed to verify that the methodology is both accurate and practical, and discuss the benefits that might accrue if the method were widely adopted.« less

Image acquisition system using on sensor compressed sampling technique

Gupta, Pravir Singh; Choi, Gwan Seong

2018-01-01

Advances in CMOS technology have made high-resolution image sensors possible. These image sensors pose significant challenges in terms of the amount of raw data generated, energy efficiency, and frame rate. This paper presents a design methodology for an imaging system and a simplified image sensor pixel design to be used in the system so that the compressed sensing (CS) technique can be implemented easily at the sensor level. This results in significant energy savings as it not only cuts the raw data rate but also reduces transistor count per pixel; decreases pixel size; increases fill factor; simplifies analog-to-digital converter, JPEG encoder, and JPEG decoder design; decreases wiring; and reduces the decoder size by half. Thus, CS has the potential to increase the resolution of image sensors for a given technology and die size while significantly decreasing the power consumption and design complexity. We show that it has potential to reduce power consumption by about 23% to 65%.

Micro/nano-bubbles are practical nanomaterials designed to increase the gas content in liquids. We attempted to use oxygen micro/nano-bubble dispersions as an oxygen-rich liquid as a means for total liquid ventilation. To determine the oxygen content in the bubble dispersion, a new method based on a spectrophotometric change between oxy- and deoxy-hemoglobin was established. The oxygen micro/nano-bubble dispersion was supplied to an experimental total ventilation liquid in anesthetic rats. Though the amount of dissolving oxygen was as low as 6 mg/L in physiological saline, the oxygen content in the oxygen micro/nano-bubble dispersion was increased to 45 mg/L. The positive correlation between the oxygen content and the life-saving time under liquid ventilation clearly indicates that the life-saving time is prolonged by increasing the oxygen content in the oxygen micro/nano-bubble dispersion. This is the first report indicating that the oxygen micro/nano-bubbles containing a sufficient amount of oxygen are useful in producing oxygen-rich liquid for the process of liquid ventilation.

Saving Can Save from Death Anxiety: Mortality Salience and Financial Decision-Making

PubMed Central

Zaleskiewicz, Tomasz; Gasiorowska, Agata; Kesebir, Pelin

2013-01-01

Four studies tested the idea that saving money can buffer death anxiety and constitute a more effective buffer than spending money. Saving can relieve future-related anxiety and provide people with a sense of control over their fate, thereby rendering death thoughts less threatening. Study 1 found that participants primed with both saving and spending reported lower death fear than controls. Saving primes, however, were associated with significantly lower death fear than spending primes. Study 2 demonstrated that mortality primes increase the attractiveness of more frugal behaviors in save-or-spend dilemmas. Studies 3 and 4 found, in two different cultures (Polish and American), that the activation of death thoughts prompts people to allocate money to saving as opposed to spending. Overall, these studies provided evidence that saving protects from existential anxiety, and probably more so than spending. PMID:24244497

Estimates of associated outdoor particulate matter health risk and costs reductions from alternative building, ventilation and filtration scenarios.

Sultan, Zuraimi M

2007-05-01

Although many studies have reported calculations of outdoor particulate matter (PM) associated externalities using ambient data, there is little information on the role buildings, their ventilation and filtration play. This study provides the framework to evaluate the health risk and cost reduction of building, ventilation and filtration strategies from outdoor PM pollution on a nationwide level and applied it to a case study in Singapore. Combining Indoor Air Quality (IAQ) and time weighted exposure models, with established concentration-response functions and monetary valuation methods, mortality and morbidity effects of outdoor PM on the population of Singapore under different building, ventilation and filtration strategies were estimated. Different interventions were made to compare the effects from the current building conditions. The findings demonstrate that building protection effect reduced approximately half the attributable health cases amounting to US$17.7 billion due to PM pollution when compared to levels computed using outdoor data alone. For residential buildings, nationwide adoption of natural ventilation from current state is associated with 28% higher cases of mortality and 13 to 38% higher cases for different morbidities, amounting to US$6.7 billion. The incurred cost is negligible compared to energy costs of air-conditioning. However, nationwide adoption of closed residence and air-conditioning are associated with outcomes including fewer mortality (10 and 6% respectively), fewer morbidities (8 and 4% respectively) and economic savings of US$1.5 and 0.9 billion respectively. The related savings were about a factor of 9 the energy cost for air-conditioning. Nationwide adoption of mechanical ventilation and filtration from current natural ventilation in schools is associated with fewer asthma hospital admissions and exacerbations; although the economic impact is not substantial. Enhanced workplace filtration reduces the mortality and morbidity cases by 14 and 13% respectively amounting to savings of up to US$2.4 billion. The huge costs savings are comparable to the average worker salary and insignificant to energy, installation and rental cost. Despite uncertainty about accurate benefits, this study shows that health and economic gain via different building, ventilation and filtration designs in minimizing ingress of outdoor PM applied to a nationwide scale can be very large. Importantly, the results suggest that PM associated externalities and legislative efforts should not only focus on ambient PM reduction policies but also include building-informed decisions.

Characteristics of Patient-Centered Medical Home Initiatives that Generated Savings for Medicare: a Qualitative Multi-Case Analysis.

PubMed

Burton, Rachel A; Lallemand, Nicole M; Peters, Rebecca A; Zuckerman, Stephen

2018-02-05

Through the Multi-Payer Advanced Primary Care Practice (MAPCP) Demonstration, Medicare, Medicaid, and private payers offered supplemental payments to 849 primary care practices that became patient-centered medical homes (PCMHs) in eight states; practices also received technical assistance and data reports. Average Medicare payments were capped at $10 per beneficiary per month in each state. Since there was variation in the eight participating states' demonstration designs, experiences, and outcomes, we conducted a qualitative multi-case analysis to identify the key factors that differentiated states that were estimated to have generated net savings for Medicare from states that did not. States' MAPCP Demonstration initiatives were comprehensively profiled in case studies based on secondary document review, three rounds of annual interviews with state staff, payers, practices, and other stakeholders, and other data sources. Case study findings were summarized in a case-ordered predictor-outcome matrix, which identified the presence or absence of key demonstration design features and experiences and arrayed states based on the amount of net savings or losses they generated for Medicare. We then used this matrix to identify initiative features that were present in at least three of the four states that generated net savings and absent from at least three of the four states that did not generate savings. A majority of the states that generated net savings: required practices to be recognized PCMHs to enter the demonstration, did not allow late entrants into the demonstration, used a consistent demonstration payment model across participating payers, and offered practices opportunities to earn performance bonuses. Practices in states that generated net savings also tended to report receiving the demonstration payments and bonuses they expected to receive, without any issues. Designers of future PCMH initiatives may increase their likelihood of generating net savings by incorporating the demonstration features we identified.

Financial Impact of Cancer Drug Wastage and Potential Cost Savings From Mitigation Strategies.

Cancer drug wastage occurs when a parenteral drug within a fixed vial is not administered fully to a patient. This study investigated the extent of drug wastage, the financial impact on the hospital budget, and the cost savings associated with current mitigation strategies. We conducted a cross-sectional study in three University of Toronto-affiliated hospitals of various sizes. We recorded the actual amount of drug wasted over a 2-week period while using current mitigation strategies. Single-dose vial cancer drugs with the highest wastage potentials were identified (14 drugs). To calculate the hypothetical drug wastage with no mitigation strategies, we determined how many vials of drugs would be needed to fill a single prescription. The total drug costs over the 2 weeks ranged from $50,257 to $716,983 in the three institutions. With existing mitigation strategies, the actual drug wastage over the 2 weeks ranged from $928 to $5,472, which was approximately 1% to 2% of the total drug costs. In the hypothetical model with no mitigation strategies implemented, the projected drug cost wastage would have been $11,232 to $149,131, which accounted for 16% to 18% of the total drug costs. As a result, the potential annual savings while using current mitigation strategies range from 15% to 17%. The financial impact of drug wastage is substantial. Mitigation strategies lead to substantial cost savings, with the opportunity to reinvest those savings. More research is needed to determine the appropriate methods to minimize risk to patients while using the cost-saving mitigation strategies.

A comparison of efficiency of birth control input between China and India.

PubMed

Liang, J; Wang, H

1994-01-01

Global world population in mid-1991 would have been 6.9% higher (an additional 366 million births) without the effective birth control programs in India and China. 260 million births in China and 110 million births in India were averted. These averted births relieved population pressure on the food supply. Without birth control, output would have decreased by 20% in China to 302 kg in 1991 and by 12% in India to 189 kg in 1991. Both India and China have between 1000 and 2000 married and fertile women per birth control worker. The manpower-input efficiency is higher by 2 times in China than in India, but the gap is closing. In China, public expenses for birth control include family planning operating expenses, family planning workers, and bonuses for single child families. World Bank estimation has determined the ratio of government to grassroots investment to be 1:2. Total investment in 1980 was RMB 1.4596 billion or about $10.00 per person. In 1980 the allowance was RMB 60.00 per year per single child family, and in 1989 the allowance should have been RMB 120.00 per year per family but was actually RMB 48.00 due to local poverty areas and low economic performance. Data were provided annually between 1971 and 1991 on total revenue, grassroots revenue, bonuses, foreign aid, and expenses per person. The expenses per person increased from RMB 2.46 in 1971 to 5.23 in 1991 or US $6.53 in 1990. Investment in birth control totaled over 21 years RMB 50.10186 billion (US $16.6557 billion), which included RMB 49.9696 from China and $40 million in foreign aid. The cost of preventing 259.585 births over this period was RMB 193.01 or US $64.16 per birth. Savings would also accrue from child rearing costs. Government savings would have amounted to RMB 3,461 billion in rural and urban areas, or 2 times China's gross national product in 1988. State costs amount to 36.5% and family costs amount to 63.5% of child rearing until 16 years of age in urban areas; the proportion in rural areas would be 20.03% and 79.97%. The prevention of 260 million births would have saved RMB 932.1 billion for the state and collectives and RMB 2,528.9 billion for families. Over 21 years, savings were RMB 50.1 billion by the state and RMB 932.1 billion by collectives. The efficiency yield would be 1:18.60 and including family savings 1:69.08. The ratio was computed for shadow prices and with a discount factor. For India, the efficiency yield was 1:57.37.

The calculation model which we developed for the cost of stone therapy and metaphylaxis in Germany some years ago with a social health insurance company is based on estimates of stone incidence, types and recurrence rates, actual costs for stone removal, and metaphylaxis (based on data from a district of the social health care system). There are 200,000 stone recurrences per year in Germany. Costs for treatment of these stones amount to $687,000,000. Stone metaphylaxis reduces the recurrence rate by some 40%. The annual cost for stone removal could be lowered by $275,300,000. Metabolic evaluation/metaphylaxis amount to $70,100,000 per year, resulting in a net saving of $205,200,000. In 1997, there were 96 days off work per stone patient resulting in 5,800,000 days off work in Germany per year. Metaphylaxis is not only medically effective in stone formers but also can lower health care cost significantly. Although health care conditions may vary from country to country, in principle this calculation model is applicable also to other countries.

In building retrofits, occupant behavior significantly impacts building energy use and is a leading factor in uncertainty when determining the effectiveness of retrofit ECMs. Current simulation-based assessment methods simplify the representation of occupant behavior by using a standard or representative set of static and homogeneous assumptions ignoring the dynamics, stochastics, and diversity of occupant's energy-related behavior in buildings. The simplification contributes to significant gaps between the simulated and measured actual energy performance of buildings. Thismore » paper presents a framework for quantifying the impact of occupant behaviors on ECM energy savings using building performance simulation. During the first step of the study, three occupant behavior styles (austerity, normal, and wasteful) were defined to represent different levels of energy consciousness of occupants regarding their interactions with building energy systems (HVAC, windows, lights and plug-in equipment). Next, a simulation workflow was introduced to determine a range of the ECM energy savings. Then, guidance was provided to interpret the range of ECM savings to support ECM decision making. Finally, a pilot study was performed in a real building to demonstrate the application of the framework. Simulation results show that the impact of occupant behaviors on ECM savings vary with the type of ECM. Occupant behavior minimally affects energy savings for ECMs that are technology-driven (the relative savings differ by less than 2%) and have little interaction with the occupants; for ECMs with strong occupant interaction, such as the use of zonal control variable refrigerant flow system and natural ventilation, energy savings are significantly affected by occupant behavior (the relative savings differ by up to 20%). Finally, the study framework provides a novel, holistic approach to assessing the uncertainty of ECM energy savings related to occupant behavior, enabling stakeholders to understand and assess the risk of adopting energy efficiency technologies for new and existing buildings.« less

Impact assessment of waste management options in Singapore.

This paper describes the application of life cycle assessment for evaluating various waste management options in Singapore, a small-island city state. The impact assessment method by SimaPro is carried out for comparing the potential environmental impacts of waste treatment options including landfilling, incineration, recycling, and composting. The inventory data include gases and leachate from landfills, air emissions and energy recovery from incinerators, energy (and emission) savings from recycling, composting gases, and transport pollution. The impact assessment results for climate change, acidification, and ecotoxicity show that the incineration of materials imposes considerable harm to both human health and the environment, especially for the burning of plastics, paper/cardboard, and ferrous metals. The results also show that, although some amount of energy can be derived from the incineration of wastes, these benefits are outweighed by the air pollution (heavy metals and dioxins/furans) that incinerators produce. For Singapore, landfill gases and leachate generate minimal environmental damage because of the nation's policy to landfill only 10% of the total disposed wastes. Land transportation and separation of waste materials also pose minimal environmental damage. However, sea transportation to the landfill could contribute significantly to acidification because of the emissions of sulfur oxides and nitrogen oxides from barges. The composting of horticultural wastes hardly imposes any environmental damage. Out of all the waste strategies, the recycling of wastes offers the best solution for environmental protection and improved human health for the nation. Significant emission savings can be realized through recycling.

Objective To assess whether the multitherapy antenatal education ‘CTLB’ (Complementary Therapies for Labour and Birth) Study programme leads to net cost savings. Design Cost analysis of the CTLB Study, using analysis of outcomes and hospital funding data. Methods We take a payer perspective and use Australian Refined Diagnosis-Related Group (AR-DRG) cost data to estimate the potential savings per woman to the payer (government or private insurer). We consider scenarios in which the intervention cost is either borne by the woman or by the payer. Savings are computed as the difference in total cost between the control group and the study group. Results If the cost of the intervention is not borne by the payer, the average saving to the payer was calculated to be $A808 per woman. If the payer covers the cost of the programme, this figure reduces to $A659 since the average cost of delivering the programme was $A149 per woman. All these findings are significant at the 95% confidence level. Significantly more women in the study group experienced a normal vaginal birth, and significantly fewer women in the study group experienced a caesarean section. The main cost saving resulted from the reduced rate of caesarean section in the study group. Conclusion The CTLB antenatal education programme leads to significant savings to payers that come from reduced use of hospital resources. Depending on which perspective is considered, and who is responsible for covering the cost of the programme, the net savings vary from $A659 to $A808 per woman. Compared with the average cost of birth in the control group, we conclude that the programme could lead to a reduction in birth-related healthcare costs of approximately 9%.

Food-related energy requirements.

PubMed

Hirst, E

1974-04-12

I have used data from input-output studies to determine the quantities of primary and electric energy consumed in the agricultural, processing, transportation, wholesale and retail trade, and household sectors for personal consumption of food. Before one draws conclusions from these results, it is important to note the assumptions and approximations used in this analysis. First, the economic input-output data published by the Department of Commerce are subject to a number of inaccuracies, including lack of complete coverage for an industry, restriction of data for proprietary reasons, and use of different time periods for different data. Second, aggregation can combine within the same sector industries whose energy intensities differ widely. For example, eating and drinking establishments probably consume more energy per dollar of sales (because of refrigerators, stoves, and freezers) than do department stores. However, both types of establishment are included in retail trade. Thus energy use for food-related retail trade may be underestimated because of aggregation. Third, the energy coefficients are subject to error. In particular, the coefficients for the agricultural and trade sectors are vulnerable because energy use within these sectors is not well documented. Finally, the scaling factor used to estimate food-related energy use for the 1960's is approximate, in that it neglects the possibility that these energy coefficients changed differently with time. Because of these limitations, which are described more fully by Herendeen (6), a number of important issues were not addressed here. such as relative energy requirements for fresh, frozen, and canned vegetables; and for soybeans as compared to beef. This analysis shows that the U.S. food cycle consumes a considerable amount of energy, about 12 percent of the total national energy budget. The residential sector, which accounts for 30 percent of the total, is the most energy-intensive sector in terms of energy consumed per dollar of food-related expenditure. This is because food-related expenditures in homes are primarily for fuel to operate kitchen appliances and automobiles. The electricity consumed in these activities constitutes 22 percent of the total amount used in the United States. More than half of the electricity is used in homes, and more than two-thirds in the trade and household sectors. Thus agriculture and processing consume little electricity relative to the total amount used. From past trends, it appears that the amount of energy used in food-related activities will continue to increase at a rate faster than the population, principally because of growing affluence, that is, the use of processed foods, purchase of meals away from home, and the use of kitchen appliances equipped with energy-intensive devices, such as refrigerators with automatic icemakers. However, fuel shortages, rapidly increasing fuel prices, the growing need to import oil, and a host of other problems related to our use of energy suggest that these past trends will not continue. Fortunately, there are many ways to reduce the amounts of energy used for food-related activities. In the home, for example, smaller refrigerators with thicker insulation would use less electricity than do present units. If closer attention were given to the use of ranges and ovens (for example, if oven doors were not opened so often) energy would be saved. Changes in eating habits could also result in energy savings. Greater reliance on vegetable and grain products, rather than meats, for protein would reduce fuel use. Similarly, a reduction in the amounts of heavily processcd foods consumed-TV dinners and frozen desserts-would save energy. Retailers could save energy by using closed freezers to store food and by reducing the amount of lighting they use. Processors could use heat recovery methods, more efficient processes, and less packaging. Shipping more food by train rather than by truck would also cut energy use. Farmers could reduce their fuel use by combining operations (for example, by harrowing, planting, and fertilizing in the same operation), by reducing tillage practices, by increasing thc use of diesel rather than gasoline engines, and by increasing labor inputs. A partial return to organic farming (that is, greater use of animal manure and crop rotation) would save energy because chemical fertilizers require large energy inputs for their production.

Saving-enhanced memory: the benefits of saving on the learning and remembering of new information.

With the continued integration of technology into people's lives, saving digital information has become an everyday facet of human behavior. In the present research, we examined the consequences of saving certain information on the ability to learn and remember other information. Results from three experiments showed that saving one file before studying a new file significantly improved memory for the contents of the new file. Notably, this effect was not observed when the saving process was deemed unreliable or when the contents of the to-be-saved file were not substantial enough to interfere with memory for the new file. These results suggest that saving provides a means to strategically off-load memory onto the environment in order to reduce the extent to which currently unneeded to-be-remembered information interferes with the learning and remembering of other information. © The Author(s) 2014.

Arterial hypertension (AH) represents a public health problem in Poland, firstly due to the huge, still growing population of patients (10.45 million patients based on NATPOL 2011 and PolSenior Surveys), and secondly because of the substantial cost of reimbursement from the National Health Fund (NHF). The most commonly used drugs in the treatment of AH include angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), the latter being associated with significantly higher unit reimbursement cost. Recent meta-analyses of randomised, controlled trials indicate that there is no medical reason to favour ARBs over ACEIs in AH treatment. To assess the clinical benefit of using ACEIs instead of ARBs and to calculate the potential savings for the payer and patients associated with changing the treatment paradigm to preferential use of ACEIs. The assessment of clinical consequences includes differences between ACEIs and ARBs in terms of average life expectancy and quality-adjusted life years (QALYs) gained. The impact of these drugs on general mortality was estimated based on the meta-analysis carried out by van Vark et al. in 2012. Patients' health-related quality of life was adjusted with Polish population utility norms derived for the EQ-5D-3L questionnaire and additionally for ACEI-induced cough-related utility decrease. Potential savings for the payer on a yearly basis were calculated for a hypothetical cohort of patients who are currently treated with ARBs and might be switched to ACEIs. The number of patients treated with ARBs and ACEIs was estimated based on NHF and IMS Health data. ACEIs were associated with a statistically significant 10% reduction in all-cause mortality, which results in extra life gained of 0.354 years (4.2 months) or an additional 0.201 QALY (2.4 months). Potential annual savings could amount to 112.0 million PLN (25.7 million EUR) and 10.5 million PLN (2.4 million EUR) for the public payer (NHF) and patients, respectively; and 1768 cardiovascular deaths per year could be prevented. Preferential use of ACEIs in comparison with ARBs in the treatment of AH is associated with substantial extension of life (including quality-adjusted life), reduction of cardiovascular deaths, and savings for the NHF and patients.

The sub-band filterbank is one of the most important modules which has the largest amount of calculation in MP3 decoding. In order to save CPU resources and integrate the sub-band filterbank part into MP3 IP core, the hardware circuit of the sub-band filterbank module is designed in this paper. A fast algorithm suit for hardware implementation is proposed and achieved on FPGA development board. The results show that the sub-band filterbank function is correct in the case of using very few registers and the amount of calculation and ROM resources are reduced greatly.

We demonstrate a smart image-packaging optical technique that uses what we believe is a new concept to save byte space when transmitting data. The technique supports a large set of images mapped into modulated speckle patterns. Then, they are multiplexed into a single package. This operation results in a substantial decreasing of the final amount of bytes of the package with respect to the amount resulting from the addition of the images without using the method. Besides, there are no requirements on the type of images to be processed. We present results that proof the potentiality of the technique.

Energy Saving Melting and Revert Reduction Technology: Improved Die Casting Process to Preserve the Life of the Inserts

2012-09-30

The goal of this project was to study the combined effects of die design, proper internal cooling and efficient die lubricants on die life. The project targeted improvements in die casting insert life by: Optomized Die Design for Reduced Surface Temperature: The life of die casting dies is significantly shorter when the die is exposed to elevated temperature for significant periods of time. Any die operated under conditions leading to surface temperature in excess of 1050oF undergoes structural changes that reduce its strength. Optimized die design can improve die life significantly. This improvement can be accomplished by means of coolingmore » lines, baffles and bubblers in the die. A key objective of the project was to establish criteria for the minimal distance of the cooling lines from the surface. This effort was supported with alloys and machining by BohlerUddeholm, Dunn Steel, HH Stark and Rex Buckeye. In plant testing and evaluation was conducted as in-kind cost share at St. Clair Die Casting. The Uddeholm Dievar steel evaluated in this program showed superior resistance to thermal fatigue resistance. Based on the experimental evidence, cooling lines could be placed as close as 0.5" from the surface. Die Life Extension by Optimized Die Lubrication: The life of die casting dies is affected by additions made to its surface with the proper lubricants. These lubricants will protect the surface from the considerable temperature peaks that occur when the molten melt enters the die. Dies will reach a significantly higher temperature without this lubricant being applied. The amount and type of the lubricant are critical variables in the die casting process. However, these lubricants must not corrode the die surface. This effort was supported with alloys and machining by BohlerUddeholm, Dunn Steel, HH Stark and Rex Buckeye. In plant testing and evaluation was conducted as in-kind cost share at St. Clair Die Casting. Chem- Trend participated in the program with die lubricants and technical support. Experiments conducted with these lubricants demonstrated good protection of the substrate steel. Graphite and boron nitride used as benchmarks are capable of completely eliminating soldering and washout. However, because of cost and environmental considerations these materials are not widely used in industry. The best water-based die lubricants evaluated in this program were capable of providing similar protection from soldering and washout. In addition to improved part quality and higher production rates, improving die casting processes to preserve the life of the inserts will result in energy savings and a reduction in environmental wastes. Improving die life by means of optimized cooling line placement, baffles and bubblers in the die will allow for reduced die temperatures during processing, saving energy associated with production. The utilization of optimized die lubricants will also reduce heat requirements in addition to reducing waste associated with soldering and washout. This new technology was predicted to result in an average energy savings of 1.1 trillion BTU's/year over a 10 year period. Current (2012) annual energy saving estimates, based on commercial introduction in 2010, a market penetration of 70% by 2020 is 1.26 trillion BTU's/year. Along with these energy savings, reduction of scrap and improvement in casting yield will result in a reduction of the environmental emissions associated with the melting and pouring of the metal which will be saved as a result of this technology. The average annual estimate of CO2 reduction per year through 2020 is 0.025 Million Metric Tons of Carbon Equivalent (MM TCE).« less

Infrastructure has become an important topic in a variety of areas of the policy debate, including energy saving and climate change. In this paper, we use an energy input-output model to evaluate the amounts of China's embodied energy use in infrastructure investment from 1992 to 2007. We also use the structure decomposition model to analyze the factors impacting the embodied energy use in infrastructure investment for the same time period. The results show that embodied energy use in infrastructure investment accounted for a significant proportion of China's total energy use with an increasing trend and reflect that improper infrastructure investment represents inefficient use of energy and other resources. Some quantitative information is provided for further determining the low carbon development potentials of China's economy.

To reduce the costs of blast-furnace smelting, the Svobodnyi Sokol plant has devised a comprehensive program of organizational-technical measures that include study of ways of reducing coke consumption. To do this, the plant began operating its blast furnaces with schungite when making foundry and conversion pig irons. Using schungite in the charge employed to make foundry iron makes it possible to save a significant (10-15%) amount of coke. The value of the coefficient that characterizes the replacement of coke by schungite varies broadly and can reach 1.0 or more, depending on the grade of iron being made and the furnacemore » operating regime. The same coefficient has a value of 0.57 kg coke/kg schungite when 12-15 kg schungite/ton pig is used to make conversion pig iron.« less

Calibrating SANS data for instrument geometry and pixel sensitivity effects: access to an extended Q range

Karge, Lukas; Gilles, Ralph

2017-01-01

An improved data-reduction procedure is proposed and demonstrated for small-angle neutron scattering (SANS) measurements. Its main feature is the correction of geometry- and wavelength-dependent intensity variations on the detector in a separate step from the different pixel sensitivities: the geometric and wavelength effects can be corrected analytically, while pixel sensitivities have to be calibrated to a reference measurement. The geometric effects are treated for position-sensitive 3He proportional counter tubes, where they are anisotropic owing to the cylindrical geometry of the gas tubes. For the calibration of pixel sensitivities, a procedure is developed that is valid for isotropic and anisotropic signals. The proposed procedure can save a significant amount of beamtime which has hitherto been used for calibration measurements. PMID:29021734

The progress of economic globalization, the rapid growth of international trade, and the maritime transportation has played an increasingly significant role in the international supply chain. As a result, worldwide seaports have suffered from a central problem, which appears in the form of massive amounts of fuel consumed and exhaust gas fumes emitted from the ships while berthed. Many ports have taken the necessary precautions to overcome this problem, while others still suffer due to the presence of technical and financial constraints. In this paper, the barriers, interconnection standards, rules, regulations, power sources, and economic and environmental analysis related to ships, shore-side power were studied in efforts to find a solution to overcome his problem. As a case study, this paper investigates the practicability, costs and benefits of switching from onboard ship auxiliary engines to shore-side power connection for high-speed crafts called Alkahera while berthed at the port of Safaga, Egypt. The results provide the national electricity grid concept as the best economical selection with 49.03 percent of annual cost saving. Moreover, environmentally, it could achieve an annual reduction in exhaust gas emissions of CO2, CO, NO x , P.M, and SO2 by 276, 2.32, 18.87, 0.825 and 3.84 tons, respectively.

Dumps of a mining-metallurgical complex of post-Soviet Republics have accumulated a huge amount of technogenic waste products. Out of them, Kazakhstan alone has preserved about 20 billion tons. In the field of technogenic waste treatment, there is still no technical solution that leads it to be a profitable process. Recent global trends prompted scientists to focus on developing energy-saving and a highly efficient melting unit that can significantly reduce specific fuel consumption. This paper reports, the development of a new technological method—smelt layer of inversion phase. The introducing method is characterized by a combination of ideal stirring and ideal displacement regimes. Using the method of affine modelling, recalculation of pilot plant’s test results on industrial sample has been obtained. Experiments show that in comparison with bubbling and boiling layers of smelt, the degree of zinc recovery increases in the layer of inversion phase. That indicates the reduction of the possibility of new formation of zinc silicates and ferrites from recombined molecules of ZnO, SiO2, and Fe2O3. Calculations show that in industrial samples of the pilot plant, the consumption of natural gas has reduced approximately by two times in comparison with fuming-furnace. The specific fuel consumption has reduced by approximately four times in comparison with Waelz-kiln. PMID:29281646

Rising health care costs above inflation are placing serious strains on the sustainability of the Australian Medicare system in its current structure. The Medicare Benefits Schedule (MBS), which lists rebates payable to patients for private medical services provided on a fee-for-service basis, is the cornerstone of the Australian health care system. Introduced in the 1980s, the MBS has changed little despite major advances in the evidence base for the practice of cardiology. We outline how we believe sensible changes to the MBS listings for four cardiac services--invasive coronary angiography, computed tomography coronary angiography, stress testing and percutaneous coronary intervention--would improve the clinical practice of cardiology and save substantial amounts of taxpayer money.

Six Sigma, a process-focused strategy and methodology for business improvement, can be used to improve care processes, eliminate waste, reduce costs, and enhance patient satisfaction. Six Sigma was introduced in 2001 at the 384-bed Red Cross Hospital (Beverwijk). During the Green Belt training, every participant was required to participate in at least one Six Sigma project. The hospital's total savings in 2004 amounted to 1.4 million dollars, for an average savings of 67,000 dollars for each of the completed 21 projects. In one project, the team designed a new admission process for the operating rooms, resulting in an average starting time nine minutes earlier. This relatively minor improvement made it possible to operate on an additional 400 patients a year and to achieve a net savings of >273,000 dollars. A second project reduced the number of patients receiving intravenous (IV) antibiotics by switching to oral administration, yielding annual savings, based on medication costs alone, of >75,000 dollars. A third project reduced the length of stay in the delivery room from 11.9 to 3.4 hours, yielding an annual savings of 68,000 dollars. The "Ultimate Cure?": Six Sigma, which entails involvement of health care workers; use of improvement tools (from industry); creation of trained project teams to tackle complex, often cross-departmental processes; data analyses; and investment in quality improvement may prove the "ultimate cure" to the current cost, quality, and safety issues that challenge health care.

Saving energy for the data collection point in WBAN network

Wireless sensor networking (WSN) has been rapidly developed and become essential in various domains including health care systems. Such systems use WSN to collect real-time medical sensed data, aiming at improving the patient safety. For instance, patients suffered from adverse events, i.e., cardiac or respiratory arrests, are monitored so as to prevent them from getting harm. Sensors are placed on, in or near the patients' body to continuously collect sensing data such as the electrocardiograms, blood oxygenation, breathing, and heart rate. In this case, the sensors form a subcategory of WSN called wireless body area network (WBAN). In WBAN, sensing data are sent to one or more data collection points called personal server (PS). The role of PS is important since it forwards sensed data, to a medical server via a Bluetooth/WLAN connection in real time to support storage of information and real-time diagnosis, the device can also issue a notification of an emergency status. Since PS is a battery-based device, when its battery is empty, it will disconnect the sensed medical data with the rest network. To best of our knowledge, very few studies that focus on saving energy for the PS. To this end, this work investigates the trade-off between energy consumption for wireless communication and the amount of sensing data. An energy consumption model for wireless communication has been proposed based on direct measurement using real testbed. According to our findings, it is possible to save energy for the PS by selecting suitable wireless technology to be used based on the amount of data to be transmitted.

Handheld personal digital assistants (PDA) are increasingly being used by physicians for a variety of information and data management purposes. We evaluated a PDA-based data management system for our acute pain service. A structured questionnaire survey was conducted to assess staff experience and attitude towards the paper system before the introduction of the PDA, and three months after introduction of the PDA system. We compared the time taken to conduct the acute pain round before and after the implementation of the PDA. The time saved in data management and the amount of paper saved were estimated. Data from 177 patients with a total of 635 acute pain follow-up visits were entered over a three-month period. User satisfaction, ease of access to drug reference and clinical guidelines were similar between the two systems. The respondents found that the PDA was easy to use but less so than the paper system (P = 0.007), in particular, when accessing a patient's cumulative data (P = 0.007). There was no missed follow-up or data entry with the use of PDA. The time taken to attend follow-up visits was similar for the two systems (Paper: 8.8 +/- 3.2 compared to PDA: 7.0 +/- 2.0 minutes, P = 0.151). The estimated annual amount of paper and time saved in data management was 650 sheets and 130 man-hours respectively. Our experience with the use of the PDA in APS was satisfactory. The PDA system can potentially reduce time and paper use and missed data entry and patient follow-up.

Development of demand forecasting tool for natural resources recouping from municipal solid waste.

Sustainable waste management requires an integrated planning and design strategy for reliable forecasting of waste generation, collection, recycling, treatment and disposal for the successful development of future residential precincts. The success of the future development and management of waste relies to a high extent on the accuracy of the prediction and on a comprehensive understanding of the overall waste management systems. This study defies the traditional concepts of waste, in which waste was considered as the last phase of production and services, by putting forward the new concept of waste as an intermediate phase of production and services. The study aims to develop a demand forecasting tool called 'zero waste index' (ZWI) for measuring the natural resources recouped from municipal solid waste. The ZWI (ZWI demand forecasting tool) quantifies the amount of virgin materials recovered from solid waste and subsequently reduces extraction of natural resources. In addition, the tool estimates the potential amount of energy, water and emissions avoided or saved by the improved waste management system. The ZWI is tested in a case study of waste management systems in two developed cities: Adelaide (Australia) and Stockholm (Sweden). The ZWI of waste management systems in Adelaide and Stockholm is 0.33 and 0.17 respectively. The study also enumerates per capita energy savings of 2.9 GJ and 2.83 GJ, greenhouse gas emissions reductions of 0.39 tonnes (CO2e) and 0.33 tonnes (CO2e), as well as water savings of 2.8 kL and 0.92 kL in Adelaide and Stockholm respectively.

Weighted generalized linear model regressions of hospital costs were estimated for the matched groups. Data Collection Data were restricted to patients at least 18 years old with inpatient stays of between 7 and 30 days. Variables available included patient demographics, primary and secondary diagnoses, hospital costs incurred for the inpatient stay, and when/if the patient had a PC consult. Principal Findings We found overall cost savings from PC of $3,426 per patient for those dying in the hospital. No significant cost savings were found for patients discharged alive; however, significant cost savings for patients discharged alive could be achieved for certain diagnoses, PC team structures, or if consults occurred within 10 days of admission. Conclusions Appropriately selected and timed PC consults with physician and RN involvement can help ensure a financially viable PC program via cost savings to the hospital. PMID:25040226

In order to investigate the issues in measurement of value of travel time savings (VTTS), the willingness-to-accept (WTA) for the private car owner is studied by using surveyed data. It is convincing that trip purpose, trip length, time savings, cost savings, income, and allowance from employee have effects on the WTA. Moreover, influences of these variables are not the same for different trip purposes. For commuting trips, effects of income and allowance from employee are significant while time savings and cost savings are dominated for leisure and shopping trips. It is also found that WTA is much higher than expected which implies that there are a group of drivers who are not prone to switching to other trip modes other than passenger car.

Wide-awake, local anesthesia, no tourniquet (WALANT) hand surgery was developed to improve access to hand surgery care while optimizing medical resources. Hand surgery in the clinic setting may result in substantial cost savings for the United States Military Health Care System (MHS) and provide a safe alternative to performing similar procedures in the operating room. A prospective cohort study was performed on the first 100 consecutive clinic-based WALANT hand surgery procedures performed at a military medical center from January 2014 to September 2015 by a single hand surgeon. Cost savings analysis was performed by using the Medical Expense and Performance Reporting System, the standard cost accounting system for the MHS, to compare procedures performed in the clinic versus the operating room during the study period. A study specific questionnaire was obtained for 66 procedures to evaluate the patient's experience. For carpal tunnel release (n = 34) and A1 pulley release (n = 33), there were 85% and 70% cost savings by having the procedures performed in clinic under WALANT compared with the main operating room, respectively. During the study period, carpal tunnel release, A1 pulley release, and de Quervain release performed in the clinic instead of the operating room amounted to $393,100 in cost savings for the MHS. There were no adverse events during the WALANT procedure. A clinic-based WALANT hand surgery program at a military medical center results in considerable cost savings for the MHS.

Worldwide, water scarcity threatens delivery of water to urban centers. Increasing water use efficiency (WUE) is often recommended to reduce water demand, especially in water-scarce areas. In this paper, agricultural water use efficiency (AWUE) is examined using the super-efficient data envelopment analysis (DEA) approach in Xi'an in Northwest China at a temporal and spatial level. The grey systems analysis technique was then adopted to identify the factors that influenced the efficiency differentials under the shortage of water resources. From the perspective of temporal scales, the AWUE increased year by year during 2004-2012, and the highest (2.05) was obtained in 2009. Additionally, the AWUE was the best in the urban area at the spatial scale. Moreover, the key influencing factors of the AWUE are the financial situations and agricultural water-saving technology. Finally, we identified several knowledge gaps and proposed water-saving strategies for increasing AWUE and reducing its water demand by: (1) improving irrigation practices (timing and amounts) based on compatible water-saving techniques; (2) maximizing regional WUE by managing water resources and allocation at regional scales as well as enhancing coordination among Chinese water governance institutes.

We consider the energy-saving potential of solid-state street lighting due to improved visual performance, weather sensitive luminance control and tracking of pedestrians and vehicles. A psychophysical experiment on the measurement of reaction time with a decision making task was performed under mesopic levels of illumination provided by a highpressure sodium (HPS) lamp and different solid-state light sources, such as daylight and warm-white phosphor converted light-emitting diodes (LEDs) and red-green-blue LED clusters. The results of the experiment imply that photopic luminances of road surface provided by solid-state light sources with an optimized spectral power distribution might be up to twice as low as those provided by the HPS lamp. Dynamical correction of road luminance against road surface conditions typical of Lithuanian climate was estimated to save about 20% of energy in comparison with constant-level illumination. The estimated energy savings due to the tracking of pedestrians and vehicles amount at least 25% with the cumulative effect of intelligent control of at least 40%. A solid-state street lighting system with intelligent control was demonstrated using a 300 m long test ground consisting of 10 solid-state street luminaires, a meteorological station and microwave motion sensor network operated via power line communication.

The Economics of Provider Payment Reform: Are Accountable Care Organizations the Answer?

PubMed

Feldman, Roger

2015-08-01

A remarkable consensus has developed that the fee-for-service (FFS) approach for paying medical providers must be replaced. This payment approach is said to increase the volume of services without improving care coordination. In response to these calls, Medicare and private payers are experimenting with payment systems that combine the basic element of FFS - a fee for each service - with arrangements that allow providers to share the savings if they hold total spending per patient below a targeted amount. Medicare's accountable care organizations (ACOs) embody the shared savings approach to payment reform. Private payers have introduced total cost of care contracting (TCOC) in several locations. This article questions the consensus that FFS must go. If the fees are too high, then someone needs to "bite the bullet" and reduce fees in key areas. Hoping to control overspending by investment in ACOs is wishful thinking. I describe the theory and practice of shared savings payment systems and summarize recent TCOC contracting initiatives in the private sector. Medicare's shared savings approach is likely to be less effective than private contracts. Cutting providers' fees would be more efficient. Finally, the new payment models in the Affordable Care Act will not ease the problem of high prices for private payers. Copyright © 2015 by Duke University Press.

Charalambous, Katerina; Bruggeman, Adriana; Lange, Manfred A

2012-01-01

Modelling the urban water balance enables the understanding of the interactions of water within an urban area and allows for better management of water resources. However, few models today provide a comprehensive overview of all water sources and uses. The objective of the current paper was to develop a user-friendly tool that quantifies and visualizes all water flows, losses and inefficiencies in urban environments. The Urban Water Flow Model was implemented in a spreadsheet and includes a water-savings application that computes the contributions of user-selected saving options to the overall water balance. The model was applied to the coastal town of Limassol, Cyprus, for the hydrologic years 2003/04-2008/09. Data were collected from the different authorities and hydrologic equations and estimations were added to complete the balance. Average precipitation was 363 mm/yr, amounting to 25.4 × 10(6)m(3)/yr, more than double the annual potable water supply to the town. Surface runoff constituted 29.6% of all outflows, while evapotranspiration from impervious areas was 21.6%. Possible potable water savings for 2008/09 were estimated at 5.3 × 10(3) m(3), which is 50% of the total potable water provided to the area. This saving would also result in a 6% reduction of surface runoff.

At global scale, the majority of world water withdrawal is for the agricultural sector, with differences among countries depending on the relevance of agri-food sector in the economy. Virtual water and water footprint could be useful to express the impact on the water resources of each production process and good with the objective to lead to a sustainable use of water at a global level. International trade could be connected to the virtual water flows, in fact through commodities importation, water poor countries can save their own water resources. The present paper focuses on the bilateral virtual water flows connected to the top ten agri-food products traded between Italy and China. Comparing the virtual water flow related to the top 10 agri-food products, the virtual water flow from Italy to China is bigger than the water flow in the opposite direction. Moreover, the composition of virtual water flows is different; Italy imports significant amounts of grey water from China, depending on the different environmental strategies adopted by the two selected countries. This difference could be also related to the fact that traded commodities are very different; the 91% of virtual water imported by Italy is connected to crops products, while the 95% of virtual water imported by China is related to the animal products. Considering national water saving and global water saving, appears that Italy imports virtual water from China while China exerts pressure on its water resources to supply the exports to Italy. This result at global scale implies a global water loss of 129.29millionm3 because, in general, the agri-food products are traded from the area with lower water productivity to the area with the higher water productivity.

2007-11-13

Influenza poses concerns about epidemic respiratory infection. Interventions designed to prevent the spread of respiratory infection within family physician (FP) offices could potentially have a significant positive influence on the health of Canadians. The main purpose of this paper is to estimate the explicit costs of such an intervention. A cost analysis of a respiratory infection control was conducted. The costs were estimated from the perspective of provincial government. In addition, a threshold analysis was conducted to estimate a threshold value of the intervention's effectiveness that could generate potential savings in terms of averted health-care costs by the intervention that exceed the explicit costs. The informational requirements for these implicit costs savings are high, however. Some of these elements, such as the cost of hospitalization in the event of contacting influenza, and the number of patients passing through the physicians' office, were readily available. Other pertinent points of information, such as the proportion of infected people who require hospitalization, could be imported from the existing literature. We take an indirect approach to calculate a threshold value for the most uncertain piece of information, namely the reduction in the probability of the infection spreading as a direct result of the intervention, at which the intervention becomes worthwhile. The 5-week intervention costs amounted to a total of $52,810.71, or $131,094.73 prorated according to the length of the flu season, or $512,729.30 prorated for the entire calendar year. The variable costs that were incurred for this 5-week project amounted to approximately $923.16 per participating medical practice. The (fixed) training costs per practice were equivalent to $73.27 for the 5-week intervention, or $28.14 for 13-week flu season, or $7.05 for an entire one-year period. Based on our conservative estimates for the direct cost savings, there are indications that the outreach facilitation intervention program would be cost effective if it can achieve a reduction in the probability of infection on the order of 0.83 (0.77, 1.05) percentage points. A facilitation intervention initiative tailored to the environment and needs of the family medical practice and walk-in clinics is of promise for improving respiratory infection control in the physicians' offices.

With the mainstream of 1,321km and located in an arid area in northwest China, the Tarim River is China's longest inland river. The Tarim basin on the northern edge of the Taklamakan desert is an extremely arid region. In this region, agricultural water consumption and allocation management are crucial to address the conflicts among irrigation water users from upstream to downstream. Since 2011, the German Ministry of Science and Education BMBF established the Sino-German SuMaRiO project, for the sustainable management of river oases along the Tarim River. The project aims to contribute to a sustainable land management which explicitly takes into account ecosystem functions and ecosystem services. SuMaRiO will identify realizable management strategies, considering social, economic and ecological criteria. This will have positive effects for nearly 10 million inhabitants of different ethnic groups. The modelling of water consumption and allocation strategies is a core block in the SuMaRiO cluster. A large-scale hydrological model (MIKE HYDRO Basin) was established for the purpose of sustainable agricultural water management in the main stem Tarim River. MIKE HYDRO Basin is an integrated, multipurpose, map-based decision support tool for river basin analysis, planning and management. It provides detailed simulation results concerning water resources and land use in the catchment areas of the river. Calibration data and future predictions based on large amount of data was acquired. The results of model calibration indicated a close correlation between simulated and observed values. Scenarios with the change on irrigation strategies and land use distributions were investigated. Irrigation scenarios revealed that the available irrigation water has significant and varying effects on the yields of different crops. Irrigation water saving could reach up to 40% in the water-saving irrigation scenario. Land use scenarios illustrated that an increase of farmland area in the lower reach gravely aggravated the water deficit, while a decrease of farmland in the upper reaches resulted in considerable benefits for all sub-catchments. A substitution of crops was also investigated, which demonstrated the potential for saving considerable amounts of irrigation water in upper and middle reaches. Overall, the results of this study provide a scientific basis for decision-making on the water consumption and allocation strategies in this arid region.

Dvořák, Lukáš; Fojtášek, Kamil

2015-05-01

Pressure regulators in the field of pneumatic mechanisms can be used as valves for saving compressed air. For example it can be used to reduce the pressure when the piston rod is retracting unloaded and thus it is possible to save some energy. However the problem is that saving valve can significantly affect the dynamics of the pneumatic system. The lower pressure in the piston rod chamber causes extension of time for retraction of the piston rod. This article compare the air consumption experimentally determined and calculated, measured curves of pressure in cylinder chambers and piston speed when saving valve is set up differently.

Improving the economic well-being of the girls and women is a key to reducing re-trafficking and in providing stability that survivors can use to rebuild their lives. The study looks at how various sociodemographic traits affected the financial capability of n = 144 women and girls who received intervention at a residential care facility in Ghana, West Africa. Three domain of financial capability are assessed in this, i.e., financial risk, financial planning, and financial saving. A scaled likelihood ratio test (chi-square difference test) was used to evaluate the significance of each direct covariate effect(%). Each of the overall goodness-of-fit indices suggested that the initial CFA model fit the data well, χ 2 (19, N = 144)  = 31.45, p = 0.04, RMSEA = 0.067 (90% CI: 0.017-0.108), TLI = 0.923, CFI = 0.948. Older women reported lower levels of financial savings than younger women. We found that women with secondary school education or higher reported significantly higher financial risk than women with less education. Women with children reported lower levels of financial saving than women without children. Married women indicated significantly more financial saving than single women. There was a significant negative effect of time spent in trafficking conditions on financial saving, indicating the highest average level of financial savings at intervention and decreased thereafter. Programs and policies in resource-scarce contexts that aim to assist trafficking survivors must go beyond providing psychosocial counseling and focus also on economic development opportunities.

Cost savings through implementation of an integrated home-based record: a case study in Vietnam.

PubMed

Aiga, Hirotsugu; Pham Huy, Tuan Kiet; Nguyen, Vinh Duc

2018-03-01

In Vietnam, there are three major home-based records (HBRs) for maternal and child health (MCH) that have been already nationally scaled up, i.e., Maternal and Child Health Handbook (MCH Handbook), Child Vaccination Handbook, and Child Growth Monitoring Chart. The MCH Handbook covers all the essential recording items that are included in the other two. This overlapping of recording items between the HBRs is likely to result in inefficient use of both financial and human resources. This study is aimed at estimating the magnitude of cost savings that are expected to be realized through implementing exclusively the MCH Handbook by terminating the other two. Secondary data collection and analyses on HBR production and distribution costs and health workers' opportunity costs. Through multiplying the unit costs by their respective quantity multipliers, recurrent costs of operations of three HBRs were estimated. Moreover, magnitude of cost savings likely to be realized was estimated, by calculating recurrent costs overlapping between the three HBRs. It was estimated that implementing exclusively the MCH Handbook would lead to cost savings of United States dollar 3.01 million per annum. The amount estimated is minimum cost savings because only recurrent cost elements (HBR production and distribution costs and health workers' opportunity costs) were incorporated into the estimation. Further indirect cost savings could be expected through reductions in health expenditures, as the use of the MCH Handbook would contribute to prevention of maternal and child illnesses by increasing antenatal care visits and breastfeeding practices. To avoid wasting financial and human resources, the MCH Handbook should be exclusively implemented by abolishing the other two HBRs. This study is globally an initial attempt to estimate cost savings to be realized through avoiding overlapping operations between multiple HBRs for MCH.

To examine the effects of work participation, intergenerational transfers and savings on the life satisfaction of older community-dwelling Malaysians. Data from the 1999 Survey on Perceptions of Needs and Problems of the Elderly on people aged 60 and over were used. The life satisfaction score was constructed from 10 questions adopted from the Life Satisfaction Inventory-A by Neugarten, Havighurst and Tobin. Multiple regression analysis was used to estimate the expected level of life satisfaction. Controlling for other variables in the model, respondents who provided assistance to and received assistance from children with savings had significantly higher life satisfaction than their counterparts, while work participation did not have any significant effect on life satisfaction. Intergenerational transfers and savings are important predictors of life satisfaction. The interdependence between generations should remain and savings habits need to be cultivated to ensure a higher life satisfaction in old age. © 2012 The Authors.

Will health fund rationalisation lead to significant premium reductions?

PubMed

Hanning, Brian

2003-01-01

It has been suggested that rationalisation of health funds will generate significant albeit unquantified cost savings and thus hold or reduce health fund premiums. 2001-2 Private Health Industry Administration Council (PHIAC) data has been used to analyse these suggestions. Payments by funds for clinical services will not vary after fund rationalisation. The savings after rationalisation will arise from reductions in management expenses, which form 10.9% of total fund expenditure. A number of rationalisation scenarios are considered. The highest theoretical industry wide saving found in any plausible scenario is 2.5%, and it is uncertain whether this level of saving could be achieved in practice. If a one off saving of this order were achieved, it would have no medium and long term impact on fund premiums increases given funds are facing cost increases of 4% to 5% per annum due to demographic changes and age standardised utilization increases. It is suggested discussions on fund amalgamation divert attention from the major factors increasing fund costs, which are substantially beyond fund control.

Economic benefit analysis of cultivating Pleurotus ostreatus with rape straw

NASA Astrophysics Data System (ADS)

Guan, Qinlan; Gong, Mingfu; Tang, Mei

2018-04-01

The cultivation of Pleurotus ostreatus with rape straw not only can save the cultivation cost of P. ostreatus, but also can reuse the resources and protect the environment. By adding different proportion of rape straw to the cultivation material of P. ostreatus, the reasonable amount of rape straw was selected and the economic benefit of P. ostreatus cultivated with the optimum amount of rape straw was analyzed. The results showed that adding 10% to 40% rape straw to the cultivation material of P. ostreatus did not affect the yield and biological conversion rate of P. ostreatus, and the ratio of production and investment of the amount of rape straw in the range of 10% to 50% was higher than of cottonseed husk alone as the main material of the formula.

Linna, Anu; Korhonen, Mirka; Airaksinen, Marja; Juppo, Anne Mari

2010-06-01

Use of external contractors is nowadays inevitable in the pharmaceutical industry. Therefore the amount of current good manufacturing practice audits has been increasing. During the audit, a large amount of items should be covered in a limited amount of time. Consequently, pharmaceutical companies should have systematic and effective ways to manage and prepare for the audits. This study is a continuation to the earlier study, where a tool for the preparation of cGMP audit was developed and its content was validated. The objective of this study was to evaluate the usefulness of the developed tool in audit preparation and during the actual cGMP audit. Three qualitative research methods were used in this study (observation, interviews, and opinion survey). First, the validity of the information given through the tool was examined by comparing the responses to the actual conditions observed during the contract manufacturer audits (n = 15). Additionally the opinions of the contract manufacturers of the tool were gathered (n = 10) and the auditors were interviewed (n = 2). The developed tool was proven to be useful in audit preparation phase from both the auditor's and the contract manufacturers' point of view. Furthermore, using the tool can also save some time when performing the audit. The results show that using the tool can give significant support in audit preparation phase and also during the actual audit.

2012-05-01

The interest in adaptive study design is evident from the growing amount of clinical research employing this model in the mid to later stages of medicines development. Little has been published on the practical application and merits of adaptive study design in early phase clinical research. This paper describes a retrospective analysis performed on a sample of 29 industry lead adaptive early phase studies commencing between 1 January 2006 and 31 December 2010 in a clinical trials unit in London, England. All studies containing at least one adaptive feature in the original protocol were included in the analysis. The scope of the analysis was to assess whether the use of adaptive study designs provided tangible benefits over the use of conventional study designs using time savings as the main measure. We conclude that the use of adaptive study design saves time in early phase research programs. This is achieved by abolishing the need for substantial amendments or by mitigating their impact on timelines and by using adaptive scheduling efficiencies.

Multiple Power-Saving MSSs Scheduling Methods for IEEE802.16e Broadband Wireless Networks

PubMed Central

2014-01-01

This work proposes two enhanced multiple mobile subscriber stations (MSSs) power-saving scheduling methods for IEEE802.16e broadband wireless networks. The proposed methods are designed for the Unsolicited Grant Service (UGS) of IEEE802.16e. To reduce the active periods of all power-saving MSSs, the base station (BS) allocates each MSS fewest possible transmission frames to retrieve its data from the BS. The BS interlaces the active periods of each MSS to increase the amount of scheduled MSSs and splits the overflowing transmission frames to maximize the bandwidth utilization. Simulation results reveal that interlacing the active periods of MSSs can increase the number of scheduled MSSs to more than four times of that in the Direct scheduling method. The bandwidth utilization can thus be improved by 60%–70%. Splitting the overflowing transmission frames can improve bandwidth utilization by more than 10% over that achieved using the method of interlacing active periods, with a sacrifice of only 1% of the sleep periods in the interlacing active period method.

Medicare's Accountable Care Organization (ACO) programs introduced shared savings to traditional Medicare, which allow providers who reduce health care costs for their patients to retain a percentage of the savings they generate. To examine ACO and market factors associated with superior financial performance in Medicare ACO programs. We obtained financial performance data from the Centers for Medicare and Medicaid Services (CMS); we derived market-level characteristics from Medicare claims; and we collected ACO characteristics from the National Survey of ACOs for 215 ACOs. We examined the association between ACO financial performance and ACO provider composition, leadership structure, beneficiary characteristics, risk bearing experience, quality and process improvement capabilities, physician performance management, market competition, CMS-assigned financial benchmark, and ACO contract start date. We examined two outcomes from Medicare ACOs' first performance year: savings per Medicare beneficiary and earning shared savings payments (a dichotomous variable). When modeling the ACO ability to save and earn shared savings payments, we estimated positive regression coefficients for a greater proportion of primary care providers in the ACO, more practicing physicians on the governing board, physician leadership, active engagement in reducing hospital re-admissions, a greater proportion of disabled Medicare beneficiaries assigned to the ACO, financial incentives offered to physicians, a larger financial benchmark, and greater ACO market penetration. No characteristic of organizational structure was significantly associated with both outcomes of savings per beneficiary and likelihood of achieving shared savings. ACO prior experience with risk-bearing contracts was positively correlated with savings and significantly increased the likelihood of receiving shared savings payments. In the first year, performance is quite heterogeneous, yet organizational structure does not consistently predict performance. Organizations with large financial benchmarks at baseline have greater opportunities to achieve savings. Findings on prior risk bearing suggest that ACOs learn over time under risk-bearing contracts. Given the lack of predictive power for organizational characteristics, CMS should continue to encourage diversity in organizational structures for ACO participants, and provide alternative funding and risk bearing mechanisms to continue to allow a diverse group of organizations to participate.

Tan, Quanyin; Li, Jinhui

2016-01-01

The use of fluorescent lamps has expanded rapidly all over the world in recent years, because of their energy-saving capability. Consequently, however, mercury emissions from production, breakage, and discard of the lamps are drawing increasing concern from the public. This article focuses on evaluating the amount of mercury used for fluorescent lamp production, as well as the potential mercury emissions during production and breakage, in mainland China. It is expected to provide a comprehensive understanding about the risks present in the mercury from fluorescent lamps, and to know about the impacts of the policies on fluorescent lamps after their implementation. It is estimated that, in 2020, mercury consumption will be about 11.30-15.69 tonnes, a significant reduction of 34.9%-37.4% from that used in 2013, owing to improvement in mercury dosing dosage technology and tighter limitations on mercury content in fluorescent lamps. With these improvements, the amount of mercury remaining in fluorescent lamps and released during production is estimated to be 10.71-14.86 and 0.59-0.83 tonnes, respectively; the mercury released from waste fluorescent lamps is estimated to be about 5.37-7.59 tonnes. Also, a significant reduction to the mercury emission can be expected when a collection and treatment system is well established and conducted in the future. © The Author(s) 2015.

The TSX Gives a Short Course in Health Economics: It's the Prices, Stupid!

The fall in Shoppers Drug Mart shares last April 8 gave a crystal-clear demonstration of the link between health expenditures and health incomes. Reacting (finally) to the excessive retail prices of generic drugs, the Ontario government effectively halved the rate of reimbursement of ingredient costs and banned the “professional allowances” (kickbacks) paid to pharmacies by generic manufacturers. Taxpayers and private payers will save hundreds of millions of dollars, and pharmacy revenues will fall by an equivalent amount. Patients will still get their drugs, with no loss of quantity, quality or even convenience; no one's health is threatened. But investor profits will fall. There are similar savings opportunities throughout the health system. Health costs are primarily a political, not an economic, problem. PMID:22043220

1974-01-01

Analysis, design, fabrication and design verification testing was conducted on the technological feasiblity of the helium pressurization regulator for the space shuttle orbital maneuvering system application. A prototype regulator was fabricated which was a single-stage design featuring the most reliable and lowest cost concept. A tradeoff study on regulator concepts indicated that a single-stage regulator with a lever arm between the valve and the actuator section would offer significant weight savings. Damping concepts were tested to determine the amount of damping required to restrict actuator travel during vibration. Component design parameters such as spring rates, effective area, contamination cutting, and damping were determined by test prior to regulator final assembly. The unit was subjected to performance testing at widely ranging flow rates, temperatures, inlet pressures, and random vibration levels. A test plan for propellant compatibility and extended life tests is included.

Metabolic engineering of microorganisms for biofuels production: from bugs to synthetic biology to fuels.

PubMed

Lee, Sung Kuk; Chou, Howard; Ham, Timothy S; Lee, Taek Soon; Keasling, Jay D

2008-12-01

The ability to generate microorganisms that can produce biofuels similar to petroleum-based transportation fuels would allow the use of existing engines and infrastructure and would save an enormous amount of capital required for replacing the current infrastructure to accommodate biofuels that have properties significantly different from petroleum-based fuels. Several groups have demonstrated the feasibility of manipulating microbes to produce molecules similar to petroleum-derived products, albeit at relatively low productivity (e.g. maximum butanol production is around 20 g/L). For cost-effective production of biofuels, the fuel-producing hosts and pathways must be engineered and optimized. Advances in metabolic engineering and synthetic biology will provide new tools for metabolic engineers to better understand how to rewire the cell in order to create the desired phenotypes for the production of economically viable biofuels.

Computer-Based Mathematics Instructions for Engineering Students

Almost every engineering course involves mathematics in one form or another. The analytical process of developing mathematical models is very important for engineering students. However, the computational process involved in the solution of some mathematical problems may be very tedious and time consuming. There is a significant amount of mathematical software such as Mathematica, Mathcad, and Maple designed to aid in the solution of these instructional problems. The use of these packages in classroom teaching can greatly enhance understanding, and save time. Integration of computer technology in mathematics classes, without de-emphasizing the traditional analytical aspects of teaching, has proven very successful and is becoming almost essential. Sample computer laboratory modules are developed for presentation in the classroom setting. This is accomplished through the use of overhead projectors linked to graphing calculators and computers. Model problems are carefully selected from different areas.

W-MAC: A Workload-Aware MAC Protocol for Heterogeneous Convergecast in Wireless Sensor Networks

PubMed Central

Xia, Ming; Dong, Yabo; Lu, Dongming

2011-01-01

The power consumption and latency of existing MAC protocols for wireless sensor networks (WSNs) are high in heterogeneous convergecast, where each sensor node generates different amounts of data in one convergecast operation. To solve this problem, we present W-MAC, a workload-aware MAC protocol for heterogeneous convergecast in WSNs. A subtree-based iterative cascading scheduling mechanism and a workload-aware time slice allocation mechanism are proposed to minimize the power consumption of nodes, while offering a low data latency. In addition, an efficient schedule adjustment mechanism is provided for adapting to data traffic variation and network topology change. Analytical and simulation results show that the proposed protocol provides a significant energy saving and latency reduction in heterogeneous convergecast, and can effectively support data aggregation to further improve the performance.

Application of Energy Integration Techniques to the Design of Advanced Life Support Systems

NASA Technical Reports Server (NTRS)

Levri, Julie; Finn, Cory

2000-01-01

Exchanging heat between hot and cold streams within an advanced life support system can save energy. This savings will reduce the equivalent system mass (ESM) of the system. Different system configurations are examined under steady-state conditions for various percentages of food growth and waste treatment. The scenarios investigated represent possible design options for a Mars reference mission. Reference mission definitions are drawn from the ALSS Modeling and Analysis Reference Missions Document, which includes definitions for space station evolution, Mars landers, and a Mars base. For each scenario, streams requiring heating or cooling are identified and characterized by mass flow, supply and target temperatures and heat capacities. The Pinch Technique is applied to identify good matches for energy exchange between the hot and cold streams and to calculate the minimum external heating and cooling requirements for the system. For each pair of hot and cold streams that are matched, there will be a reduction in the amount of external heating and cooling required, and the original heating and cooling equipment will be replaced with a heat exchanger. The net cost savings can be either positive or negative for each stream pairing, and the priority for implementing each pairing can be ranked according to its potential cost savings. Using the Pinch technique, a complete system heat exchange network is developed and heat exchangers are sized to allow for calculation of ESM. The energy-integrated design typically has a lower total ESM than the original design with no energy integration. A comparison of ESM savings in each of the scenarios is made to direct future Pinch Analysis efforts.

2015-01-01

Improving economic resources of impoverished youth may alter intentions to engage in sexual risk behaviors by motivating positive future planning to avoid HIV risk and by altering economic contexts contributing to HIV risk. Yet, few studies have examined the effect of economic-strengthening on economic and sexual behaviors of orphaned youth, despite high poverty and high HIV infection in this population. Hierarchal longitudinal regressions were used to examine the effect of a savings-led economic empowerment intervention, the Suubi-Maka Project, on changes in orphaned adolescents’ cash savings and attitudes toward savings and HIV-preventive practices over time. We randomized 346 Ugandan adolescents, aged 10–17 years, to either the control group receiving usual orphan care plus mentoring (n = 167) or the intervention group receiving usual orphan care plus mentoring, financial education, and matched savings accounts (n = 179). Assessments were conducted at baseline, 12, and 24 months. Results indicated that intervention adolescents significantly increased their cash savings over time (b = $US12.32, ±1.12, p < .001) compared to adolescents in the control group. At 24 months post-baseline, 92% of intervention adolescents had accumulated savings compared to 43% in the control group (p < .001). The largest changes in savings goals were the proportion of intervention adolescents valuing saving for money to buy a home (ΔT1−T0 = +14.9, p < .001), pursue vocational training (ΔT1−T0 = +8.8, p < .01), and start a business (T1−T0 = +6.7, p < .01). Intervention adolescents also had a significant relative increase over time in HIV-preventive attitudinal scores (b = +0.19, ±0.09, p < .05), most commonly toward perceived risk of HIV (95.8%, n = 159), sexual abstinence or postponement (91.6%, n = 152), and consistent condom use (93.4%, n = 144). In addition, intervention adolescents had 2.017 significantly greater odds of a maximum HIV-prevention score (OR = 2.017, 95%CI: 1.43–2.84). To minimize HIV risk throughout the adolescent and young adult periods, long-term strategies are needed to integrate youth economic development, including savings and income generation, with age-appropriate combination prevention interventions.

Low-Emissivity, Energy-Control, Retrofit Window Film: Final Report

DOE Office of Scientific and Technical Information (OSTI.GOV)

Winckler, Lisa

Solutia Performance Films, utilizing funding from the U.S. Department of Energy's Buildings Technologies Program, completed research to develop, validate, and commercialize a range of cost-effective, low-emissivity energy-control retrofit window films with significantly improved emissivity over current technology. These films, sold under the EnerLogic® trade name, offer the energy-saving properties of modern low-e windows, with several advantages over replacement windows, such as: lower initial installation cost, a significantly lower product carbon footprint, and an ability to provide a much faster return on investment. EnerLogic® window films also offer significantly greater energy savings than previously available with window films with similar visiblemore » light transmissions. EnerLogic® window films offer these energy-saving advantages over other window films due to its ability to offer both summer cooling and winter heating savings. Unlike most window films, that produce savings only during the cooling season, EnerLogic® window film is an all-season, low-emissivity (low-e) film that produces both cooling and heating season savings. This paper will present technical information on the development hurdles as well as details regarding the following claims being made about EnerLogic® window film, which can be found at www.EnerLogicfilm.com: 1. Other window film technologies save energy. EnerLogic® window film's patent-pending coating delivers excellent energy efficiency in every season, so no other film can match its annual dollar or energy consumption savings. 2. EnerLogic® window film is a low-cost, high-return technology that compares favorably to other popular energy-saving measures both in terms of energy efficiency and cost savings. In fact, EnerLogic® window film typically outperforms most of the alternatives in terms of simple payback. 3. EnerLogic® window film provides unparalleled glass insulating capabilities for window film products. With its patent-pending low-e technology, EnerLogic® window film has the best insulating performance of any film product available. The insulating power of EnerLogic® window film gives single-pane windows the annual insulating performance of double-pane windows - and gives double-pane windows the annual insulating performance of triple-pane windows.« less

Design and Analysis of a Flexible, Reliable Deep Space Life Support System

NASA Technical Reports Server (NTRS)

Jones, Harry W.

2012-01-01

This report describes a flexible, reliable, deep space life support system design approach that uses either storage or recycling or both together. The design goal is to provide the needed life support performance with the required ultra reliability for the minimum Equivalent System Mass (ESM). Recycling life support systems used with multiple redundancy can have sufficient reliability for deep space missions but they usually do not save mass compared to mixed storage and recycling systems. The best deep space life support system design uses water recycling with sufficient water storage to prevent loss of crew if recycling fails. Since the amount of water needed for crew survival is a small part of the total water requirement, the required amount of stored water is significantly less than the total to be consumed. Water recycling with water, oxygen, and carbon dioxide removal material storage can achieve the high reliability of full storage systems with only half the mass of full storage and with less mass than the highly redundant recycling systems needed to achieve acceptable reliability. Improved recycling systems with lower mass and higher reliability could perform better than systems using storage.

Minimizing energy dissipation of matrix multiplication kernel on Virtex-II

NASA Astrophysics Data System (ADS)

Choi, Seonil; Prasanna, Viktor K.; Jang, Ju-wook

2002-07-01

In this paper, we develop energy-efficient designs for matrix multiplication on FPGAs. To analyze the energy dissipation, we develop a high-level model using domain-specific modeling techniques. In this model, we identify architecture parameters that significantly affect the total energy (system-wide energy) dissipation. Then, we explore design trade-offs by varying these parameters to minimize the system-wide energy. For matrix multiplication, we consider a uniprocessor architecture and a linear array architecture to develop energy-efficient designs. For the uniprocessor architecture, the cache size is a parameter that affects the I/O complexity and the system-wide energy. For the linear array architecture, the amount of storage per processing element is a parameter affecting the system-wide energy. By using maximum amount of storage per processing element and minimum number of multipliers, we obtain a design that minimizes the system-wide energy. We develop several energy-efficient designs for matrix multiplication. For example, for 6×6 matrix multiplication, energy savings of upto 52% for the uniprocessor architecture and 36% for the linear arrary architecture is achieved over an optimized library for Virtex-II FPGA from Xilinx.

A Large-Scale Design Integration Approach Developed in Conjunction with the Ares Launch Vehicle Program

NASA Technical Reports Server (NTRS)

Redmon, John W.; Shirley, Michael C.; Kinard, Paul S.

2012-01-01

This paper presents a method for performing large-scale design integration, taking a classical 2D drawing envelope and interface approach and applying it to modern three dimensional computer aided design (3D CAD) systems. Today, the paradigm often used when performing design integration with 3D models involves a digital mockup of an overall vehicle, in the form of a massive, fully detailed, CAD assembly; therefore, adding unnecessary burden and overhead to design and product data management processes. While fully detailed data may yield a broad depth of design detail, pertinent integration features are often obscured under the excessive amounts of information, making them difficult to discern. In contrast, the envelope and interface method results in a reduction in both the amount and complexity of information necessary for design integration while yielding significant savings in time and effort when applied to today's complex design integration projects. This approach, combining classical and modern methods, proved advantageous during the complex design integration activities of the Ares I vehicle. Downstream processes, benefiting from this approach by reducing development and design cycle time, include: Creation of analysis models for the Aerodynamic discipline; Vehicle to ground interface development; Documentation development for the vehicle assembly.

Stability of zinc stearate under alpha irradiation in the manufacturing process of SFR nuclear fuels

2018-03-01

The manufacture of new fuels for sodium-cooled fast reactors (SFRs) will involve powders derived from recycling existing fuels in order to keep on producing electricity while saving natural resources and reducing the amount of waste produced by spent MOX fuels. Using recycled plutonium in this way will significantly increase the amount of 238Pu, a high energy alpha emitter, in the powders. The process of shaping powders by pressing requires the use of a solid lubricant, zinc stearate, to produce pellets with no defects compliant with the standards. The purpose of this study is to determine the impact of alpha radiolysis on this additive and its lubrication properties. Experiments were conducted on samples in contact with PuO2, as well as under external helium ion beam irradiation, in order to define the kinetics of radiolytic gas generation. The yield results relating to the formation of these gases (G0) show that the alpha radiation of plutonium can be simulated using external helium ion beam irradiation. The isotopic composition of plutonium has little impact on the yield. However, an increased yield was globally observed with increasing the mean linear energy transfer (LET). A radiolytic degradation process is proposed.

Energy Saving Melting and Revert Reduction Technology (Energy SMARRT): Development of CCT Diagrams

2011-08-20

One of the most energy intensive industries in the U.S. today is in the melting and casting of steel alloys for use in our advanced technological society. While the majority of steel castings involve low or mild carbon steel for common construction materials, highly-alloyed steels constitute a critical component of many industries due to their excellent properties. However, as the amount of alloying additions increases, the problems associated with casting these materials also increases, resulting in a large waste of energy due to inefficiency and a lack of basic information concerning these often complicated alloy systems. Superaustenitic stainless steels constitutemore » a group of Fe-based alloys that are compositionally balanced to have a purely austenitic matrix and exhibit favorable pitting and crevice corrosion resistant properties and mechanical strength. However, intermetallic precipitates such as sigma (³) and Laves can form during casting or exposure to high-temperature processing, which degrade the corrosion and mechanical properties of the material. Knowledge of the times and temperatures at which these detrimental phases form is imperative if a company is to efficiently produce castings of high quality in the minimum amount of time, using the lowest amount of energy possible, while producing the least amount of material waste. Anecdotal evidence from company representatives revealed that large castings frequently had to be scrapped due to either lower than expected corrosion resistance or extremely low fracture toughness. It was suspected that these poor corrosion and / or mechanical properties were directly related to the type, amount, and location of various intermetallic phases that formed during either the cooling cycle of the castings or subsequent heat treatments. However, no reliable data existed concerning either the time-temperature-transformation (TTT) diagrams or the continuous-cooling-transformation (CCT) diagrams of the super-austenitics. The goal of this study was to accurately characterize the solid-solid phase transformations seen in cast superaustenitic stainless steels. Heat treatments were performed to understand the time and temperature ranges for intermetallic phase formations in alloys CN3MN and CK3McuN. Microstructures were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy and wavelength dispersive spectroscopy (EDS, WDS). In this way TTT and CCT diagrams could be developed for the matrix of samples chosen. As this study consisted of basic research into the development of TTT and CCT diagrams as an aid to the US steel casting industry, there is no formal commercialization plan associated with this task other than presentations and publications via the Steel Founders Society of America to their members. The author is confident that the data contained in this report can be used by steel foundries to refine their casting procedures in such a way as to reduce the amount of waste produced and energy wasted by significantly reducing or eliminating the need for remelting or recasting of material due to unwanted, premature intermetallic formation. This development of high alloy steel CCT diagrams was predicted to result in an average energy savings of 0.05 trillion BTU's/year over a 10 year period (with full funding). With 65% of the proposed funding, current (2011) annual energy saving estimates, based on initial dissemination to the casting industry in 2011and market penetration of 97% by 2020, is 0.14 trillion BTU's/year. The reduction of scrap and improvement in casting yield will also result in a reduction of environmental emissions associated with the melting and pouring of the steel. The average annual estimate of CO2 reduction per year through 2020 is 0.003 Million Metric Tons of Carbon Equivalent (MM TCE)« less

Vaccination of all healthy children against rotavirus (RV) has been recommended, since the availability of vaccines, both in Europe (PIDJ) and Italy (pediatricians). The aims of universal vaccination against RV include the protection of children against moderate/severe gastroenteritis forms by RV (GARV), prevent hospitalizations, reduce the severity and duration of the disease, and reduce morbidity and socioeconomic costs. Payers need to informed regarding the efficacy and the healthcare utilization related to RV vaccination in order to decide in favour of its extensive implementation. The aim of this paper is to assess the clinical and financial impact of the extensive vaccination aganist RV both at National and Regional level. Particular attention, compared to the previous analysis (Standaert et al, 2008) has been given to the influence of herd immunity (HI) on cost-utility results of vaccination against-RV. Methods. The analysis was conducted with the Markovian model previously used by Standaert B et al and updated for comparing costs and benefits associated with a situation of vaccination anti-RV that includes efficacy data due to HI, with a situation without vaccination. For the base case is assumed an annual coverage of 90%, where the effect of HI is present in the population at risk (0-5 years) and extended to children who have not been vaccinated, adding as conservative assumption, a further 10% to the efficacy of the vaccine, compared to 15% determined by several published studies. Two analysis have been made based on this model: a cost-utility analysis that compared vaccination with two doses of RIX441410 administered at 2 and 3 months after birth compared with no vaccination from National Health Service and Society perspective; a budget impact analysis at National and Regional level. The evaluation has as its main element the reduction of cases of infection through universal vaccination and consequent reduction of Garv events and nosocomial infections. Results. From the NHS perspective, in a cohort of 555,791 born in Italy in 2011, the annual number of hospitalizations due to RV infections in the absence of vaccination is estimated to be 14,550 units. Assuming that 90% of newborns receive two doses of the vaccine, and including an additional effect of HI to the efficacy of the vaccine, vaccination would lead to a reduction of 71% of cases of Garv (176,804 cases in less) and a 86% of hospitalizations due to Garv (12,913 fewer cases), with an impact on quality of life and mortality as a consequence of vaccination. The introduction of the vaccine would lead to a gain of 0.0014 QALYs and 0.0022 life-years gained per child compared to a situation without vaccination (assuming a discount rate of 3% on future benefits). The reduction of GARV also would lead to a strong economic impact. The introduction of the vaccine would lead to a saving of € 25.41 per child or a saving of more than € 14 million for the whole population included in the analysis. Cost reduction increase significantly from the perspective of society and introducing the indirect costs due to lost productivity. In this case, the savings due to the introduction of vaccination would increase to € 67,747,654 in the total cohort, or € 121.89 per child. In an alternative scenario, where HI is excluded, RIX4414 remains dominant (0.0013 QALYs gained and € 22.14 per child saved). The budget impact analysis shows that, as early as the second year, the additional cost of the vaccine is more than offset by a reduction in costs of the disease, which leads to savings for the NHS, which increases from year 3. In a time horizon of 5 years (without the discount rate), the savings for the NHS amount to € 34,440,314. These savings would amount to a cost reduction of € 4.64 per child over 5 years (€ 0.93 per year). The savings due to the introduction of the vaccine were mainly due to a reduction in costs associated with hospitalizations. The budget impact analysis at regional level, has taken a vaccine cost of € 30.00 per dose. Cases of diarrhoea before after vaccination are reduced in each region, based on the number of births, ranging from a minimum of 399 cases avoided for Valle d'Aosta to a maximum of 31,116 cases avoided in Lombardy. In a similar way, the number of hospitalizations due to GARV are reduced considerably, from a minimum of 36 cases in Valle d'Aosta to a maximum of 3,096 in Lombardy. Obviously, these reductions are greater in regions with 30,000 or more births per year. Conclusions. This study suggests that a universal vaccination anti-RV with 2 doses of RIX4414 brings significant clinical and economic benefits both at National and Regional level. The indirect effects of the vaccine (HI) could generate protection even in unvaccinated children with health gain and a number of cases by GARV much less than those that would vaccinating small groups of children and with a cost of illness, for NHS, which would be reduced significantly, despite the additional costs of the vaccine as early as the second year of vaccination. Productivity losses due to absence from work of a parent, as well as all other costs included in the model, show that is precisely the society to pay the consequences, from economic and social point of view. Considering the citizen in the role of private payer, we must stress as for him, the savings generated by vaccination, whether universal or with demand for cost-sharing by the health service, prove significant with a major health gain for the population under study.

A CLS-based survivable and energy-saving WDM-PON architecture

We propose and demonstrate an improved survivable and energy-saving WDM-PON with colorless ONUs. It incorporates both energy-saving and self-healing operations. A simple effective energy-saving scheme is proposed by including an energy-saving control unit in the OLT and a control unit at each ONU. The energy-saving scheme realizes both dozing and sleep (offline) modes, which greatly improves the energy-saving efficiency for WDM-PONs. An intelligent protection switching scheme is designed in the OLT, which can distinguish if an ONU is in dozing/sleep (offline) state or a fiber is faulty. Moreover, by monitoring the optical power of each channel on both working and protection paths, the OLT can know the connection status of every fiber path, thus facilitating an effective protection switching and a faster failure recovery. The improved WDM-PON architecture not only significantly reduces energy consumption, but also performs self-healing operation in practical operation scenarios. The scheme feasibility is experimentally verified with 10 Gbit/s downstream and 1.25 Gbit/s upstream transmissions. We also examine the energy-saving efficiency of our proposed energy-saving scheme by simulation, which reveals that energy saving mainly arises from the dozing mode, not from the sleep mode when the ONU is in the online state.

Energy education programmes for children are hypothesized to have great potential to save energy. Such interventions are often assumed to impact child and family behaviours. Here, using a cluster-randomized controlled trial with 30 Girl Scout troops in Northern California, we assess the efficacy of two social cognitive theory-based interventions focused on residential and food-and-transportation energy-related behaviours of Girl Scouts and their families. We show that Girl Scouts and parents in troops randomly assigned to the residential energy intervention significantly increased their self-reported residential energy-saving behaviours immediately following the intervention and after more than seven months of follow-up, compared with controls. Girl Scouts in troops randomly assigned to the food-and-transportation energy intervention significantly increased their self-reported food-and-transportation energy-saving behaviours immediately following the intervention, compared with controls, but not at follow-up. The results demonstrate that theory-based, child-focused energy interventions have the potential to increase energy-saving behaviours among both children and their parents.

Reducing toner consumption is an important task in modern printing devices and has a significant positive ecological impact. Existing toner saving approaches have two main drawbacks: appearance of hardcopy in toner saving mode is worse in comparison with normal mode; processing of whole rendered page bitmap requires significant computational costs. We propose to add small holes of various shapes and sizes to random places inside a character bitmap stored in font cache. Such random perforation scheme is based on processing pipeline in RIP of standard printer languages Postscript and PCL. Processing of text characters only, and moreover, processing of each character for given font and size alone, is an extremely fast procedure. The approach does not deteriorate halftoned bitmap and business graphics and provide toner saving for typical office documents up to 15-20%. Rate of toner saving is adjustable. Alteration of resulted characters' appearance is almost indistinguishable in comparison with solid black text due to random placement of small holes inside the character regions. The suggested method automatically skips small fonts to preserve its quality. Readability of text processed by proposed method is fine. OCR programs process that scanned hardcopy successfully too.

We assess how different scenarios of cardiovascular disease (CVD) prevention, aimed at meeting targets set by the World Health Organization (WHO) for 2025), may impact healthcare spending in Quebec, Canada over the 2050 horizon. We provide long-term forecasts of healthcare use and costs at the Quebec population level using a novel dynamic microsimulation model. Using both survey and administrative data, we simulate the evolution of the Quebec population's health status until death, through a series of dynamic transitions that accounts for social and demographic characteristics associated with CVD risk factors. A 25% reduction in CVD mortality between 2012 and 2025 achieved through decreased incidence could contain the pace of healthcare cost growth towards 2050 by nearly 7 percentage points for consultations with a physician, and by almost 9 percentage points for hospitalizations. Over the 2012-2050 period, the present value of cost savings is projected to amount to C$13.1 billion in 2012 dollars. The years of life saved due to improved life expectancy could be worth another C$38.2 billion. Addressing CVD mortality directly instead would bring about higher healthcare costs, but would generate more value in terms of years of life saved, at C$69.6 billion. Potential savings associated with plausible reductions in CVD, aimed at reaching a World Health Organization target over a 12-year period, are sizeable and may help address challenges associated with an aging population.

This study assessed the association between community savings group participation and consistent condom use (CCU) among female sex workers (FSW) in Iringa, Tanzania. Using cross-sectional data from a survey of venue-based FSW (n = 496), logistic regression was used to examine the associations between financial indicators including community savings group participation and CCU. Over one-third (35%) of the women participated in a savings group. Multivariable regression results indicated that participating in a savings group was significantly associated with nearly two times greater odds of CCU with new clients in the last 30 days (aOR = 1.77, 95% CI 1.10-2.86). Exploratory mediation analysis indicated that the relationship between savings group participation and CCU was partially mediated by financial security, as measured by monthly income. Findings indicate that community savings groups may play an important role in reducing sexual risk behaviors of FSW and hold promise as part of comprehensive, community-led HIV prevention strategies among FSW.

Background People encounter various moral issues that involve making decisions for others by giving advice. Objective This study investigated the characteristics of providing suggestions for oneself versus providing suggestions for others in ethical decision-making and the differences between them based on Construal Level Theory (CLT). Methods A total of 768 undergraduate students from three universities in China were randomly assigned to eight groups on the basis of a grid of two Construal Levels (self or others) by two different numbers of people saved (5 people or 15 people) by two problem situations (trolley problem vs. footbridge problem). The investigation examined participants’ decisions to opt to take action or refrain from action that would have the consequence of saving more people. Results The main effects of Construal Level (F1, 752 = 6.46, p = .011), saving number (F1, 752 = 35.81, p < .001), and problem situation type (F1, 752 = 330.55, p < .001) were all significant. The interaction of the problem situation and saving number (F1, 752 = 1.01, p = .31), and social distance and saving number (F1, 752 = 0.85, p = .36), and interaction of the three independent factors (F1, 752 = 0.47, p = .49) were not significant. However, the interaction of social distance and problem situation (F1, 752 = 9.46, p = .002) was significant. Results indicated the participants utilized a component of utilitarian reasoning in the decision-making, and their behaviors appeared more utilitarian at low Construal Levels (CLs) compared to high. Conclusion CLs, saving numbers, and problem situation significantly affected moral decision-making and exhibited significant interaction. Making decisions for oneself (low-construal) rather than giving advice to others (high-construal) was one important factor that determined whether the people were utilitarian or not. Utilitarian considerations are more relevant in impersonal dilemmas. PMID:25689521

Mucopolysaccharidoses (MPS) occur due to deficiency in the activity of enzymes that catalyze the breakdown of glycosaminoglycans. MPS VII is caused by deficiency of the beta-glucuronidase enzyme (GUSB). This study aimed to enhance the technique to measure GUSB activity by reducing the amount of reagents and the size of the DBS, as well as to determine some biochemical parameters of enzyme of healthy individuals. The measurement of GUSB in 3 and 1.2mm DBS (with reagents reduced 2.5- and fourfold) was correlated and the precision of the technique was tested. Optimal pH, Km and Vmax, and thermostability parameters were determined and time and temperature of sample storage were established. The correlations among the techniques were significant. Although the correlation coefficient was similar, fourfold reduction was selected. pH4.4 had the highest enzyme activity. GUSB's Km was 1.25mM, while Vmax was 594.48nmol/h/mL. After pre-incubation of the sample at 60°C, its activity dropped from 100% to 15.8% at 120min. GUSB activity significantly decreased after 45days of storage at 4, 25, and 37°C. This research allowed a previously described technique for MPS VII diagnosis to be adapted for smaller amounts of sample and reagents. That will facilitate the use of smaller amounts of samples, which may be used for other techniques and to save material. Given the importance of early MPS VII diagnosis due to the severity of the disease, using reliable diagnostic techniques in DBS is essential.

The aim of the present study was to examine subjective cognitive impairment among adult patients with hoarding disorder (HD). Eighty-three patients with HD and 46 age- and gender-matched healthy control (HC) participants received a diagnostic interview and completed measures of subjective cognitive functioning and motivations for saving behavior, as well as measures of hoarding severity, depression, anxiety, stress, and obsessive-compulsive disorder (OCD) symptoms. The HD group reported more impairment than did the HC group in domains of memory, distractibility, blunders, memory for names, and inattention. These differences generally remained significant when controlling for comorbid symptoms. In the HD group, the degree of cognitive impairment was significantly correlated with severity of saving and acquiring behaviors, although results were attenuated when controlling for comorbid symptoms (overall HD severity, but not saving behavior specifically, remained significantly correlated with cognitive impairment). Subjective cognitive impairment was further associated with a desire to save possessions in order to avoid forgetting, and these results remained significant when controlling for comorbid symptoms. These results comport with current behavioral models of HD that emphasize decision-making deficits, as well as clinician observations suggestive of impaired cognitive function, and complement a growing body of neuropsychological testing studies.

We analyze steady state and out-of-steady-state effects of the transition in adult longevity on the national saving rate using historical data and international panel data. The rise in adult life expectancy has a large and statistically significant effect on aggregate saving. The effects have been especially pronounced in East Asia because its mortality transition was very rapid. Gains in life expectancy are much more important than declines in child dependency. Population aging may not lead to lower saving rates in the future if life expectancy and the duration of retirement continue to increase. PMID:18167514

Household survey data for 10 countries are used to quantify and test the importance of price and nonprice factors on residential water demand and investigate complementarities between household water-saving behaviors and the average volumetric price of water. Results show (1) the average volumetric price of water is an important predictor of differences in residential consumption in models that include household characteristics, water-saving devices, attitudinal characteristics and environmental concerns as explanatory variables; (2) of all water-saving devices, only a low volume/dual-flush toilet has a statistically significant and negative effect on water consumption; and (3) environmental concerns have a statistically significant effect on some self-reported water-saving behaviors. While price-based approaches are espoused to promote economic efficiency, our findings stress that volumetric water pricing is also one of the most effective policy levers available to regulate household water consumption.

It is possible to dramatically improve the performance, reliability, and maintainability of vehicles and other similarly complex equipment if improved sensing and diagnostics systems are available. Each year military and commercial maintenance personnel unnecessarily replace, at scheduled intervals, significant amounts of lubricant fluids in vehicles, weapon systems, and supporting equipment. Personnel draw samples of fluids and send them to test labs for analysis to determine if replacement is necessary. Systematic use of either on-board (embedded) lubricant quality analysis capabilities will save millions of dollars each year in avoided fluid changes, saved labor, prevented damage to mechanical components while providing associated environmental benefits. This paper discusses the design, the manufacturing, and the evaluation of robust optical sensors designed to monitor the condition of industrial fluids. The sensors reported are manufactured from bulk fused silica substrates. They incorporate three-dimensional micro fluidic circuitry side-by-side with three-dimensional wave guided optical networks. The manufacturing of the optical waveguides are completed using a direct-write process based on the use of femtosecond laser pulses to locally alter the structure of the glass substrate at the nano-level. The microfluidic circuitry is produced using the same femtosecond laser based process, followed by an anisotropic wet chemical etching step. Data will be presented regarding the use of these sensors to monitor the quality of engine oil and possibly some other vehicle lubricants such as hydraulic oil.

This research was conducted in support of two branches of the EPA ENERGY STAR program, whose overall goal is to reduce, through voluntary market-based means, the amount of carbon dioxide emitted in the U.S. The primary objective was to collect data for the ENERGY STAR Office Equipment program on the after-hours power state of computers, monitors, printers, copiers, scanners, fax machines, and multi-function devices. We also collected data for the ENERGY STAR Commercial Buildings branch on the types and amounts of ''miscellaneous'' plug-load equipment, a significant and growing end use that is not usually accounted for by building energy managers.more » This data set is the first of its kind that we know of, and is an important first step in characterizing miscellaneous plug loads in commercial buildings. The main purpose of this study is to supplement and update previous data we collected on the extent to which electronic office equipment is turned off or automatically enters a low power state when not in active use. In addition, it provides data on numbers and types of office equipment, and helps identify trends in office equipment usage patterns. These data improve our estimates of typical unit energy consumption and savings for each equipment type, and enables the ENERGY STAR Office Equipment program to focus future effort on products with the highest energy savings potential. This study expands our previous sample of office buildings in California and Washington DC to include education and health care facilities, and buildings in other states. We report data from twelve commercial buildings in California, Georgia, and Pennsylvania: two health care buildings, two large offices (> 500 employees each), three medium offices (50-500 employees), four education buildings, and one ''small office'' that is actually an aggregate of five small businesses. Two buildings are in the San Francisco Bay area of California, five are in Pittsburgh, Pennsylvania, and five are in Atlanta, Georgia.« less

Growth and development of house sparrows (Passer domesticus) in response to chronic food restriction throughout the nestling period.

Killpack, Tess L; Karasov, William H

2012-06-01

Birds have evolved phenotypic plasticity in growth and developmental patterns in order to respond to fluctuating environmental conditions and to mitigate the impact of poor feeding on fitness. Chronic food shortage can occur during chick development in the wild, and the responses of altricial birds have not been thoroughly studied. House sparrow (Passer domesticus) nestlings were raised in the laboratory on age-specific meal sizes (controls) or meal sizes 25% less than age-specific amounts (food-restricted) and analyzed at 6, 9 and 12 days post-hatch for differences in growth and development. Food-restricted birds had significantly reduced body mass and body temperature, but skeletal growth was maintained with respect to controls. Muscle mass was significantly reduced and muscle water content was slightly, though not significantly, higher in food-restricted birds, which may reflect slight developmental immaturity. Assimilation organ masses, summed enzymatic capacity of the intestine and lipid content of the liver were significantly reduced in food-restricted birds. Findings from this study indicate that altricial birds experiencing chronic, moderate food restriction throughout the nestling period may allocate resources to structural growth through energy-saving reductions in mass of assimilation organs and body temperature.

ADVANCED INTEGRATION OF MULTI-SCALE MECHANICS AND WELDING PROCESS SIMULATION IN WELD INTEGRITY ASSESSMENT

The potential to save trillions of BTU’s in energy usage and billions of dollars in cost on an annual basis based on use of higher strength steel in major oil and gas transmission pipeline construction is a compelling opportunity recognized by both the US Department of Energy (DOE). The use of high-strength steels (X100) is expected to result in energy savings across the spectrum, from manufacturing the pipe to transportation and fabrication, including welding of line pipe. Elementary examples of energy savings include more the 25 trillion BTUs saved annually based on lower energy costs to produce the thinner-walled high-strengthmore » steel pipe, with the potential for the US part of the Alaskan pipeline alone saving more than 7 trillion BTU in production and much more in transportation and assembling. Annual production, maintenance and installation of just US domestic transmission pipeline is likely to save 5 to 10 times this amount based on current planned and anticipated expansions of oil and gas lines in North America. Among the most important conclusions from these studies were: • While computational weld models to predict residual stress and distortions are well-established and accurate, related microstructure models need improvement. • Fracture Initiation Transition Temperature (FITT) Master Curve properly predicts surface-cracked pipe brittle-to-ductile initiation temperature. It has value in developing Codes and Standards to better correlate full-scale behavior from either CTOD or Charpy test results with the proper temperature shifts from the FITT master curve method. • For stress-based flaw evaluation criteria, the new circumferentially cracked pipe limit-load solution in the 2007 API 1104 Appendix A approach is overly conservative by a factor of 4/π, which has additional implications. . • For strain-based design of girth weld defects, the hoop stress effect is the most significant parameter impacting CTOD-driving force and can increase the crack-driving force by a factor of 2 depending on strain-hardening, pressure level as a % of SMYS, and flaw size. • From years of experience in circumferential fracture analyses and experimentation, there has not been sufficient integration of work performed for other industries into analogous problems facing the oil and gas pipeline markets. Some very basic concepts and problems solved previously in these fields could have circumvented inconsistencies seen in the stress-based and strain-based analysis efforts. For example, in nuclear utility piping work, more detailed elastic-plastic fracture analyses were always validated in their ability to predict loads and displacements (stresses and strains). The eventual implementation of these methodologies will result in acceleration of the industry adoption of higher-strength line-pipe steels.« less

Evaluating Cool Impervious Surfaces: Application to an Energy-Efficient Residential Roof and to City Pavements

NASA Astrophysics Data System (ADS)

Rosado, Pablo Javier

Summer urban heat island (UHI) refers to the phenomenon of having higher urban temperatures compared to the those in surrounding suburban and rural areas. Higher urban air temperatures lead to increased cooling demand, accelerates the formation of smog, and contributes to the generation of greenhouse gas emissions. Dark-colored impervious surfaces cover a significant fraction of an urban fabric, and as hot and dry surfaces, are a major contributor to the UHI effect. Adopting solar-reflective ("cool") roofs and cool pavements, and increasing the urban vegetation, are strategies proven to mitigate urban heat islands. These strategies often have an "indirect" effect (ambient cooling) and "direct" effect (change in solar energy flux entering the conditioned space) on the energy use of buildings. This work investigates some elements of the UHI mitigation strategies, specifically the annual direct effect of a cool roof, and the direct and indirect effects of cool pavements. The first topic researched in this paper consists in an experimental assessment of the direct effects from replacing a conventional dark roof with a highly energy-efficient cool roof. The study measures and calculates the annual benefits of the cool roof on the cooling and heating energy uses, and the associated emission reductions. The energy savings attributed to the cool roof are validated by measuring the difference between the homes in the heat loads that entered the conditioned space through the ceiling and HVAC ducts. Fractional annual cooling energy savings (26%) were 2.6 times the 10% daily cooling energy savings measured in a previous study that used a white coating to increase the albedo of an asphalt shingle roof by the same amount (0.44). The improved cooling energy savings (26% vs. 10%) may be attributed to the cool tile's above-sheathing ventilation, rather than to its high thermal mass. The roof also provided energy savings during the heating season, yielding fractional annual gas heating savings of 4% and electric heating savings of 3%. The slightly positive fractional annual heating energy savings likely resulted from the tile roof's high thermal capacitance, which increased the overnight temperature of the attic air. Thus cool tile roofs should be perceived as a technology that provides energy and environmental benefits during the cooling season as well as the heating season. The second topic investigates the direct and indirect effects of cool pavements on the energy use of California's building stock. First, a simple urban canyon model was developed to calculate the canyon albedo after the user provides the solar position, canyon orientation, and dimensions of the canyon walls, road, and setbacks. Next, a method is presented to correct the values of temperature changes obtained from previous urban climate models to values that would be obtained from canyon geometries that distinguish between road and setbacks (e.g. sidewalk, front yard). The new canyon model is used to scale the temperature changes obtained from a recent urban climate model that simulated the climatological impact of cool pavements on various California cities. The adjusted temperature changes are then combined with building energy simulations to investigate the effect of cool pavements on the cooling, heating, and lighting energy uses of buildings as well as the environmental impact related to these energy uses. Net (direct + indirect) conditioning (cooling + heating) energy savings and environmental savings from cool pavements were smaller in residential buildings than in commercial buildings. Additionally, residential buildings strongly dominate the building stock in all of the evaluated cities. Therefore, even though most cities yielded conditioning energy and environmental savings, they were small due to the minuscule savings from the residential buildings. When increasing the albedo by 0.20 of all public pavements in different California cities, Los Angeles was the city with the largest savings, yielding only 0.60% in Primary Energy Demand and 0.30% in Global Warming Potential (GWP). Some of the cities experienced even a small net penalty in GWP of up to 0.20%.

The Benefit/Cost Study portion of the NASA-sponsored Energy Efficient Engine Component Development and Integration program was successful in achieving its objectives: identification of air transport propulsion system technology requirements for the years 2000 and 2010, and formulation of programs for developing these technologies. It is projected that the advanced technologies identified, when developed to a state of readiness, will provide future commercial and military turbofan engines with significant savings in fuel consumption and related operating costs. These benefits are significant and far from exhausted. The potential savings translate into billions of dollars in annual savings for the airlines. Analyses indicate that a significant portion of the overall savings is attributed to aerodynamic and structure advancements. Another important consideration in acquiring these benefits is developing a viable reference technology base that will permit engines to operate at substantially higher overall pressure ratios and bypass ratios. Results have pointed the direction for future research and a comprehensive program plan for achieving this was formulated. The next major step is initiating the program effort that will convert the advanced technologies into the expected benefits.

Field Test Evaluation of Conservation Retrofits of Low-Income, Single-Family Buildings in Wisconsin: Blower-Door-Directed Infiltration Reduction Procedure, Field Test Implementation and Results

DOE Office of Scientific and Technical Information (OSTI.GOV)

Gettings, M.B.

A blower-door-directed infiltration retrofit procedure was field tested on 18 homes in south central Wisconsin. The procedure, developed by the Wisconsin Energy Conservation Corporation, includes recommended retrofit techniques as well as criteria for estimating the amount of cost-effective work to be performed on a house. A recommended expenditure level and target air leakage reduction, in air changes per hour at 50 Pascal (ACH50), are determined from the initial leakage rate measured. The procedure produced an average 16% reduction in air leakage rate. For the 7 houses recommended for retrofit, 89% of the targeted reductions were accomplished with 76% of themore » recommended expenditures. The average cost of retrofits per house was reduced by a factor of four compared with previous programs. The average payback period for recommended retrofits was 4.4 years, based on predicted energy savings computed from achieved air leakage reductions. Although exceptions occurred, the procedure's 8 ACH50 minimum initial leakage rate for advising retrofits to be performed appeared a good choice, based on cost-effective air leakage reduction. Houses with initial rates of 7 ACH50 or below consistently required substantially higher costs to achieve significant air leakage reductions. No statistically significant average annual energy savings was detected as a result of the infiltration retrofits. Average measured savings were -27 therm per year, indicating an increase in energy use, with a 90% confidence interval of 36 therm. Measured savings for individual houses varied widely in both positive and negative directions, indicating that factors not considered affected the results. Large individual confidence intervals indicate a need to increase the accuracy of such measurements as well as understand the factors which may cause such disparity. Recommendations for the procedure include more extensive training of retrofit crews, checks for minimum air exchange rates to insure air quality, and addition of the basic cost of determining the initial leakage rate to the recommended expenditure level. Recommendations for the field test of the procedure include increasing the number of houses in the sample, more timely examination of metered data to detect anomalies, and the monitoring of indoor air temperature. Though not appropriate in a field test of a procedure, further investigation into the effects of air leakage rate reductions on heating loads needs to be performed.« less

Increasing Resiliency Through Renewable Energy Microgrids

DOE Office of Scientific and Technical Information (OSTI.GOV)

Anderson, Katherine H; DiOrio, Nicholas A; Cutler, Dylan S

This paper describes a methodology to quantify the economic and resiliency benefit provided by renewable energy (RE) in a hybrid RE-storage-diesel microgrid. We present a case study to show how this methodology is applied to a multi-use/ multi-function telecommunications facility in southern California. In the case study, we first identify photovoltaic (PV) and battery energy storage system (BESS) technologies that minimize the lifecycle cost of energy at the site under normal, grid-connected operation. We then evaluate how those technologies could be incorporated alongside existing diesel generators in a microgrid to increase resiliency at the site, where resiliency is quantified inmore » terms of the amount of time that the microgrid can sustain the critical load during a grid outage. We find that adding PV and BESS to the existing backup diesel generators with a fixed fuel supply extends the amount of time the site could survive an outage by 1.8 days, from 1.7 days for the existing diesel-only backup system to 3.5 days for the PV/diesel/BESS hybrid system. Furthermore, even after diesel fuel supplies are exhausted, the site can continue to operate critical loads during daytime hours using just the PV/BESS when there is sufficient solar resource. We find that the site can save approximately $100,000 in energy costs over the 25-year lifecycle while doubling the amount of time they can survive an outage. The methodology presented here provides a template for increasing resiliency at telecomm sites by implementing renewable energy solutions, which provide additional benefits of carbon emission reduction and energy cost savings.« less

Rebound Effects in the Context of Developing Country Efficiency

DOE Office of Scientific and Technical Information (OSTI.GOV)

de la Rue du Can, Stephane; McNeil, Michael A.; Leventis, Greg

Energy efficiency-related “rebound effects” usually refer to the tendency of most consumers to increase their use of energy services in response to efficiency measures that have reduced their energy costs. This phenomenon is one reason why energy efficiency policies often result in lower energy savings than engineering-based estimates predict. Rebound effects have been the subject of intense debate in the field of energy efficiency policy for many years.1 In the past, the focus of this debate has been on the perceived loss of the expected energy savings and related benefits resulting from the rebound effects. However, more recently, there hasmore » been a growing recognition that policymakers need to consider the health, economic and other non-energy benefits that often result from the increase in energy services represented by user “rebound effects”. This is especially true in developing countries where basic energy service demands—such as lighting, heating, cooling, and refrigeration of food—are often not being met. As economic conditions improve and household incomes increase, demand for increased energy services (such as space conditioning and appliances) tends to rise rapidly. Improving energy efficiency reduces the amount of energy needed to produce one unit of energy service output (for example an hour of cooling at 21°C delivered for X vs Y kWh). Greater efficiency therefore often enables more rapid increased in energy services (and sometimes access), expanding the amount of services that can be provided by a fixed amount (or cost) of energy.« less

Cost implications for changing candidacy or access to service within a publicly funded healthcare system?

PubMed

O'Neill, Ciaran; Lamb, Brian; Archbold, Sue

2016-04-01

Undue attention in the allocation of healthcare resources can be given to expenditures as opposed to expenditures avoided. This can be particularly apparent when expenditures avoided fall across different budget holders and budgetary pressures are strained. The paper presents estimates of the potential savings attributable to the adoption of new hearing assistive technologies in Britain between 1992 and 2014 based on multivariate analyses of survey data. The reduction in service use among the hearing impaired between 1992 and 2014 is estimated to amount to between £53 and £92 million per annum. Issues in estimating the impact of widening candidature for cochlear implants on costs exist related to potential savings. This research begins to lay a firmer evidence base for such work as well as identifying some of the challenges.

Variation of magnetic properties with mischmetal content in the resource saving magnets of MM-Fe-B ribbons

NASA Astrophysics Data System (ADS)

Li, Zhu-bai; Wang, Li-chen; Geng, Xiao-peng; Hu, Feng-xia; Sun, Ji-rong; Shen, Bao-gen

2017-03-01

Magnetic materials of MM-Fe-B (MM=mischmetal) ribbons were prepared using melt spinning method by varying the content of MM. The ribbons contain minor phases besides the main phase of Re2Fe14B. X-ray techniques show that the diffraction peak intensities of the minor phase Fe3B vary with the content of constituent elements, indicating that the amount of minor phase could be tunable. The squareness of hysteresis loop is the best in MM13Fe80.5B6.5 ribbons, which should mainly ascribe to the less amount of minor phase. Henkel plots verify the more uniform magnetization reversals in MM13Fe80.5B6.5 ribbons, and the energy product achieves to the maximum of 12.74 MGOe with the coercivity of 6.50 kOe. With the increase of MM content the coercivity increases monotonically, and reaches to 9.13 kOe in MM15Fe77.5B7.5 ribbons, which should be related with the nature of the defects in the main phase. These investigations show that optimizing the content of constituent elements and phase constitution could improve magnetic properties in the resource-saving magnets of MM-Fe-B ribbons.

Immunoinformatics: an integrated scenario

Tomar, Namrata; De, Rajat K

2010-01-01

Genome sequencing of humans and other organisms has led to the accumulation of huge amounts of data, which include immunologically relevant data. A large volume of clinical data has been deposited in several immunological databases and as a result immunoinformatics has emerged as an important field which acts as an intersection between experimental immunology and computational approaches. It not only helps in dealing with the huge amount of data but also plays a role in defining new hypotheses related to immune responses. This article reviews classical immunology, different databases and prediction tools. It also describes applications of immunoinformatics in designing in silico vaccination and immune system modelling. All these efforts save time and reduce cost. PMID:20722763

Water-saving interventions assessment framework: an application for the Urmia Lake Restoration Program

NASA Astrophysics Data System (ADS)

Shadkam, Somayeh; Oel, Pieter; Kabat, Pavel; Ludwig, Fulco

2017-04-01

Increasing water demand often results in unsustainable water use leaving insufficient amounts of water for sustaining natural environments. Therefore, to save natural resources water-saving interventions have been introduced to the environmental policy agenda in many (semi)-arid regions. Many policies, however, have failed reaching their objectives to increase water availability for the environment. This calls for a comprehensive tool to assess water-saving policies. Therefore, this study introduces a constructive framework to assess the policies by estimating five components: 1) Total water demand under socio-economic scenarios, 2) Water supply under climate change scenarios, 3) Water withdrawal for different sectors, 4) Water depletion and 5) Environmental flow. The framework, was applied to assess Urmia Lake Restoration Program (ULRP), which aims to restore the drying Urmia Lake in north-western Iran by increasing the lake inflow by 3.1×106m3yr-1. Results suggest that although the ULRP helps to increase inflow by up to 57% it is unlikely to fully reach its target. The analysis shows that there are three main reasons for the potential poor performance. The first reason is decreasing return flows due to increasing irrigation efficiency. This means that the expected increase in lake inflow volume is smaller than the volume saved by increasing irrigation efficiency. The second reason is increased depletion which is due to neglecting the fact that agricultural water demand is currently higher than available water for agriculture. As a result, increasing water use efficiency may result in increased water depletion. The third reason is ignoring the potential impact of climate change, which might decrease future water availability by 3% to 15%. Our analysis suggests that to reach the intervention target, measures need to focus on reducing Water demand and Water depletion rather than on reducing Water withdrawals. The assessment framework can be used to comprehensively assess water-saving intervention plans, particularly in water-stressed basins.

Chronic kidney disease (CKD) is a disorder with high morbidity and mortality worldwide whose complications generate multiple costs. In Ecuador, only a few healthcare institutions have implemented management protocols aimed to reduce costs and to improve the quality of life of patients. The aim of this study is to evaluate the short-term (1-year) and long-term (5-year) costs and savings in the management of secondary hyperparathyroidism (SHPT) of hemodialyzed CKD patients by comparing calcitriol and paricalcitol in a large social security hospital in Quito, Ecuador. The estimation model assessed the resources used in the management of SHPT by comparing prospectively the cost savings within 1-year and 5-year time horizon with calcitriol and paricalcitol. Hospitalization, erythropoietin (EPO), treatment doses, intravenous iron consumption, and medical supplies were estimated according international references, based on the initial parathormone level (iPTH) of patients. The Ecuadorian National Reference costs (2014-2015) and institutional costs were used to calculate treatment costs. A statistical sensitivity analysis was also performed. The study was based on data from 354 patients of whom 147 (41.4 %) had a value of iPTH in the range 300-600 pg/ml, 45 (12.8 %) in the range 601-800 pg/ml, and 162 (45.7 %) over 800 pg/ml. The 1-year estimated costs per patient for calcitriol and paricalcitol, respectively, were: medication, 63.88 USD and 1,123.44 USD; EPO, 19,522.95 USD and 16,478 USD; intravenous iron 143.21 USD and 187.76 USD. Yearly hospitalization costs per patient were 11,647.99 USD with calcitriol and 8,019.41 USD with paricalcitol. Total yearly costs per patient amounted to 31,378.02 USD with calcitriol and 25,809.50 USD with paricalcitol. Total savings using paricalcitol were 5,568.52 USD per patient compared with calcitriol. The 5-year cumulative medication costs were 319 USD for calcitriol and 2,403 USD for paricalcitol; EPO with calcitriol was 97,615 USD and with paricalcitol 82,394 USD; intravenous iron with calcitriol was 716 USD and paricalcitol 939 USD. Hospitalization costs for patients with calcitriol and paricalcitol were 43,095 USD and 62,595 USD, respectively. Total savings using paricalcitol amounted 32,414 USD per patient compared with calcitriol. Paricalcitol use generated more cost savings than calcitriol after 1 and 5 years.

Energy-efficient building design in cold climates: Schools as a case study

NASA Astrophysics Data System (ADS)

Rangel Ruiz, Rocio

Buildings account for great amounts of greenhouse gas emissions. In terms of energy, buildings account for one third of the total amount of energy used in the country every year! Schools account for 14 percent of the energy used annually in commercial and institutional buildings. Further, schools are one of the most commonly constructed building types in Canada and spaces such as classrooms are often duplicated. This makes them preferred candidates for the research that was undertaken where energy-efficient solutions that can be transferred to different school designs were derived. Throughout the study, the Commercial Building Incentive Program (CBIP) was used as a benchmark. The objectives of the study were to demonstrate energy-efficient concepts, provide a case study to evaluate solutions, develop typological models and provide an understanding of the innovation process. The technological and societal aspects of the energy-efficient design were addressed. With respect to the technological aspects, the first step was the analysis of conventional design using a school in Calgary as a case study. The optimization of conventional design was undertaken using computer modeling to identify best practice solutions. Aspects that were included in the studies were lighting design, envelope characteristics, HVAC systems and building plant systems. The inclusion of passive design included the analysis of daylighting and natural ventilation. Computer modeling was used to assess daylighting in classrooms with unilateral and bilateral daylighting. Illuminance levels, glare and light distribution were evaluated. The study of natural ventilation was undertaken using literature review. Airflow and outdoor temperatures were the focus to identify solutions that could be incorporated into the design of classrooms. It was concluded that achieving excellence in energy efficiency in schools could be achieved using readily available technologies. Energy savings of up to 63 percent better than Canada's Model National Energy Code for Buildings (MNECB) reference case and utility cost savings of 30,000 (on a 50,000 annual cost) were achieved through conventional design optimization. Additional energy savings of three percent and utility cost savings of $7,000 were seen when passive strategies were included in the design. With respect to the societal aspects, an exploratory research study was undertaken to examine innovation. Architects and energy consultants were interviewed. All design professionals included in the study had participated in projects approved for a grant under CBIP. The purpose of the study was to identify drivers and barriers to energy efficiency. The study demonstrated that external and internal innovation pressures have a significant effect on whether or not the technology is adopted. Suggestions for reducing barriers and further promoting energy efficiency are discussed in this thesis. It is expected that the research will not only aid designers in assessing projects with regard to local priorities, but will also provide building guidelines that serve as tools for the development of the Canadian energy compliance for CO2 emissions.

Amount of water needed to save 1 m3 of water: life cycle assessment of a flow regulator

2017-06-01

Water saving devices in the sanitary equipment, such as flow regulators, are assumed to be environmentally advantageous even though their environmental benefit has never been compared to the environmental burden caused during their production und disposal. Therefore, a life cycle assessment according to ISO 14044 has been conducted to identify and quantify the environmental effects throughout the lifespan of a flow regulator. The analysis comprises the production of materials, manufacturing of components at suppliers, the assembly at NEOPERL®, all transports, savings of water and thermal energy during use as well as waste incineration including energy recovery in the end-of-life stage. Results show that the production of one flow regulator causes 0.12 MJ primary energy demand, a global warming potential of 5.9 g CO2-equivalent, and a water consumption of 30.3 ml. On the other hand, during a use of 10 years, it saves 19,231 MJ primary energy, 1223 kg CO2-equivalent, and avoids a water consumption of 790 l (166,200 l water use). Since local impacts of water consumption are more relevant than volumes, consequences of water consumption have been analyzed using recently developed impact assessment models. Accordingly, the production of a flow regulator causes 8.5 ml freshwater depletion, 1.4 × 10-13 disability adjusted life years, and 4.8 × 10-6 potentially disappeared fractions of species m2 a. Even though avoided environmental impacts resulting from water savings highly depend on the region where the flow regulator is used, the analysis has shown that environmental benefits are at least 15,000 times higher than impacts caused during the production.

In-office diagnostic arthroscopy for knee and shoulder intra-articular injuries its potential impact on cost savings in the United States

PubMed Central

2014-01-01

Background The purpose of this analysis was to determine whether in office diagnostic needle arthroscopy (Visionscope Imaging System [VSI]) can provide for improved diagnostic assessment and; more cost effective care. Methods Data on arthroscopy procedures in the US for deep seated pathology in the knee and shoulder were used (Calendar Year 2012). These procedures represent approximately 25-30% of all arthroscopic procedures performed annually. Sensitivities, specificities, positive predictive, and negative predictive values for MRI analysis of this deep seated pathology from systematic reviews and meta-analyses were used in assessing for false positive and false negative MRI findings. The costs of performing diagnostic and surgical arthroscopy procedures (using 2013 Medicare reimbursement amounts); costs associated with false negative findings; and the costs for treating associated complications arising from diagnostic and therapeutic arthroscopy procedures were then assessed. Results In patients presenting with medial meniscal pathology (ICD9CM diagnosis 836.0 over 540,000 procedures in CY 2012); use of the VSI system in place of MRI assessment (standard of care) resulted in a net cost savings to the system of $151 million. In patients presenting with rotator cuff pathology (ICD9CM 840.4 over 165,000 procedures in CY2012); use of VSI in place of MRI similarly saved $59 million. These savings were realized along with more appropriate care as; fewer patients were exposed to higher risk surgical arthroscopic procedures. Conclusions The use of an in-office arthroscopy system can: possibly save the US healthcare system money; shorten the diagnostic odyssey for patients; potentially better prepare clinicians for arthroscopic surgery (when needed) and; eliminate unnecessary outpatient arthroscopy procedures, which commonly result in surgical intervention.

The purpose of this study is to determine the amount of energy being used, the cost of this energy, and to recommend projects that will reduce energy consumption for Buildings 101, 104, 107, 114, 116, 118, 119, 120, 122, 125 and 138, located in the Forest Glen Complex, which is part of the Walter Reed Army Medical Center (WRAMC). Executive Order No. 12003, 20 July 1977, established energy conservation goals for existing Federal facilities requiring a reduction of 20% in the average energy use in FY 85 from the average annual energy requirements in FY 75. The Energy Conservation Investmentmore » Program (ECIP) is a Military Construction funded program for retrofitting existing DOD facilities to make them more energy efficient and thus providing substantial savings in utility costs. Each project is assessed in terms of source energy saved, the value of the energy and the capital and operating costs of the changes. The ECIP guidance provides two criteria for evaluating energy saving opportunities. These are an energy/cost ratio (E/C) and a benefit/cost ratio (B/C). For FY 84 the E/C ratio must be 13 or more with a B/C greater than one. Beginning with FY 85, ECIP projects will be prioritized on the basis of the greatest life cycle payback as determined by the savings to investment ratio (SIR). Overall projects and discrete portions of projects must be life cycle cost effective (SIR equal to or greater than 1). All energy savings projected in FY 85 shall be based on full occupancy of the buildings in the study.« less

Assessment of Energy Efficiency Improvement and CO2 Emission Reduction Potentials in India's Cement Industry

DOE Office of Scientific and Technical Information (OSTI.GOV)

Morrow, III, William R.; Hasanbeigi, Ali; Xu, Tengfang

2012-12-03

India’s cement industry is the second largest in the world behind China with annual cement production of 168 Mt in 2010 which accounted for slightly greater than six percent of the world’s annual cement production in the same year. To produce that amount of cement, the industry consumed roughly 700 PJ of fuel and 14.7 TWh of electricity. We identified and analyzed 22 energy efficiency technologies and measures applicable to the processes in the Indian cement industry. The Conservation Supply Curve (CSC) used in this study is an analytical tool that captures both the engineering and the economic perspectives ofmore » energy conservation. Using a bottom-up electricity CSC model and compared to an electricity price forecast the cumulative cost-effective plant-level electricity savings potential for the Indian cement industry for 2010- 2030 is estimated to be 83 TWh, and the cumulative plant-level technical electricity saving potential is 89 TWh during the same period. The grid-level CO2 emissions reduction associated with cost-effective electricity savings is 82 Mt CO2 and the electric grid-level CO2 emission reduction associated with technical electricity saving potential is 88 Mt CO2. Compared to a fuel price forecast, an estimated cumulative cost-effective fuel savings potential of 1,029 PJ with associated CO2 emission reduction of 97 Mt CO2 during 2010-2030 is possible. In addition, a sensitivity analysis with respect to the discount rate used is conducted to assess the effect of changes in this parameter on the results. The result of this study gives a comprehensive and easy to understand perspective to the Indian cement industry and policy makers about the energy efficiency potential and its associated cost over the next twenty years.« less

Fatal alcohol-related traffic crashes increase subsequent to changes to and from daylight savings time.

Hicks, G J; Davis, J W; Hicks, R A

1998-06-01

On the hypothesis that sleepiness and alcohol interact to increase the risk of alcohol-related traffic fatalities, the percentages of alcohol-related fatal traffic crashes were assessed for the entire state of New Mexico for the years 1989-1992, for each of the seven days that preceded the changes to and from Daylight Savings Time and for each of the 14 days which followed the changes to and from Daylight Savings Time. Consistent with our hypothesis the percentage of alcohol-related fatal crashes increased significantly during the first seven days after these changes in Daylight Savings Time.

Advanced Imaging Utilization and Cost Savings Among Medicare Shared Savings Program Accountable Care Organizations: An Initial Exploratory Analysis.

PubMed

Rosenkrantz, Andrew B; Duszak, Richard

2018-03-01

The purpose of this study was to explore associations between CT and MRI utilization and cost savings achieved by Medicare Shared Savings Program (MSSP)-participating accountable care organizations (ACOs). Summary data were obtained for all MSSP-participating ACOs (n = 214 in 2013; n = 333 in 2014). Multivariable regressions were performed to assess associations of CT and MRI utilization with ACOs' total savings and reaching minimum savings rates to share in Medicare savings. In 2014, 54.4% of ACOs achieved savings, meeting minimum rates to share in savings in 27.6%. Independent positive predictors of total savings included beneficiary risk scores (β = +20,265,720, P = .003) and MRI events (β = +19,964, P = .018) but not CT events (β = +2,084, P = .635). Independent positive predictors of meeting minimum savings rates included beneficiary risk scores (odds ratio = 2108, P = .001) and MRI events (odds ratio = 1.008, P = .002), but not CT events (odds ratio = 1.002, P = .289). Measures not independently associated with savings were total beneficiaries; beneficiaries' gender, age, race or ethnicity; and Medicare enrollment type (P > .05). For ACOs with 2013 and 2014 data, neither increases nor decreases in CT and MRI events between years were associated with 2014 total savings or meeting savings thresholds (P ≥ .466). Higher MRI utilization rates were independently associated with small but significant MSSP ACO savings. The value of MRI might relate to the favorable impact of appropriate advanced imaging utilization on downstream outcomes and other resource utilization. Because MSSP ACOs represent a highly select group of sophisticated organizations subject to rigorous quality and care coordination standards, further research will be necessary to determine if these associations are generalizable to other health care settings.

MODELING RETIREE HEALTH COSTS: This Issue Brief examines the uncertainty of health care expenses in retirement by using a Monte Carlo simulation model to estimate the amount of savings needed to cover health insurance premiums and out-of-pocket health care expenses. This type of simulation is able to account for the uncertainty related to individual mortality and rates of return, and computes the present value of the savings needed to cover health insurance premiums and out-of-pocket expenses in retirement. These observations were used to determine asset targets for having adequate savings to cover retiree health costs 50, 75, and 90 percent of the time. NOT ENOUGH SAVINGS: Many individuals will need more money than the amounts reported in this Issue Brief because this analysis does not factor in the savings needed to cover long-term care expenses, nor does it take into account the fact that many individuals retire prior to becoming eligible for Medicare. However, some workers will need to save less than what is reported if they keep working in retirement and receive health benefits as active workers. WHO HAS RETIREE HEALTH BENEFITS BEYOND MEDICARE?: About 12 percent of private-sector employers report offering any Medicare supplemental health insurance. This increases to about 40 percent among large employers. Overall, nearly 22 percent of retirees age 65 and older had retiree health benefits in 2005 to supplement Medicare coverage. As recently as 2006, 53 percent of retirees age 65 and older were covered by Medicare Part D, 24 percent had outpatient prescription drug coverage through an employment-based plan. Only 10 percent had no prescription drug coverage. INDIVIDUALLY PURCHASED MEDICARE SUPPLEMENTS, 2008: Among those who purchase Medigap and Medicare Part D prescription drug coverage at age 65 in 2008, men would need between $79,000 and $159,000 with median prescription drug expenses (50th percentile and 90th percentiles, respectively), and between $156,000 and $331,000 with prescription spending that is at the 90th percentile. Women would need between $108,000 and $184,000 with median prescription drug expenses (50th and 90th percentiles, respectively), and between $217,000 and $390,000 with prescription spending that is at the 90th percentile. The savings needed for couples would range from $194,000 at the 50th percentile to $635,000 at the 90th percentile. EMPLOYMENT-BASED BENEFITS, 2008: Among those who have employment-based retiree health benefits to supplement Medicare, but who must pay their own premiums, men would need between $102,000 and $196,000 in current savings (50th and 90th percentiles, respectively) to cover health care costs in retirement. Women would need between $137,000 and $224,000, respectively, due to their greater longevity. The savings needed for couples would range from $154,000 to $376,000. INDIVIDUALLY PURCHASED MEDICARE SUPPLEMENTS, 2018: Among those who purchase Medigap and Medicare Part D prescription drug coverage at age 65 in 2018 (currently age 55), men would need between $132,000 and $266,000 with median prescription drug expenses (50th and 90th percentiles, respectively), and between $261,000 and $555,000 with prescription spending that is at the 90th percentile. Women would need between $181,000 and S308,000 with median prescription drug expenses (50th and 90th percentiles), and between S364,000 and $654,000 with prescription spending that is at the 90th percentile. The savings needed for couples would range from $325,000 at the 50th percentile to S1,064,000 at the 90th percentile. RETIREE HEALTH MAY BE DRIVING LONGER TIME IN THE WORK FORCE: The declining availability of retiree health benefits may partly explain the rising labor force participation rate among individuals ages 55-64. Between 1996 and 2006, the labor force participation rate increased from 67 percent to 69.6 percent for men and from 49.6 percent to 58.2 percent for women.

Urban waste management is becoming an increasingly complex task, absorbing a huge amount of resources, and having a major environmental impact. The design of a waste management system consists in various activities, and one of these is related to the definition of shift schedules for both personnel and vehicles. This activity has a great incidence on the tactical and operational cost for companies. In this paper, we propose an integer programming model to find an optimal solution to the integrated problem. The aim is to determine optimal schedules at minimum cost. Moreover, we design a fast and effective heuristic to face large-size problems. Both approaches are tested on data from a real-world case in Southern Italy and compared to the current practice utilized by the company managing the service, showing that simultaneously solving these problems can lead to significant monetary savings.

REUSABLE PROPULSION ARCHITECTURE FOR SUSTAINABLE LOW-COST ACCESS TO SPACE

NASA Technical Reports Server (NTRS)

Bonometti, J. A.; Dankanich, J. W.; Frame, K. L.

2005-01-01

The primary obstacle to any space-based mission is, and has always been, the cost of access to space. Even with impressive efforts toward reusability, no system has come close to lowering the cost a significant amount. It is postulated here, that architectural innovation is necessary to make reusability feasible, not incremental subsystem changes. This paper shows two architectural approaches of reusability that merit further study investments. Both #inherently# have performance increases and cost advantages to make affordable access to space a near term reality. A rocket launched from a subsonic aircraft (specifically the Crossbow methodology) and a momentum exchange tether, reboosted by electrodynamics, offer possibilities of substantial reductions in the total transportation architecture mass - making access-to-space cost-effective. They also offer intangible benefits that reduce risk or offer large growth potential. The cost analysis indicates that approximately a 50% savings is obtained using today#s aerospace materials and practices.

Gradient retention prediction of acid-base analytes in reversed phase liquid chromatography: a simplified approach for acetonitrile-water mobile phases.

PubMed

Andrés, Axel; Rosés, Martí; Bosch, Elisabeth

2014-11-28

In previous work, a two-parameter model to predict chromatographic retention of ionizable analytes in gradient mode was proposed. However, the procedure required some previous experimental work to get a suitable description of the pKa change with the mobile phase composition. In the present study this previous experimental work has been simplified. The analyte pKa values have been calculated through equations whose coefficients vary depending on their functional group. Forced by this new approach, other simplifications regarding the retention of the totally neutral and totally ionized species also had to be performed. After the simplifications were applied, new prediction values were obtained and compared with the previously acquired experimental data. The simplified model gave pretty good predictions while saving a significant amount of time and resources. Copyright © 2014 Elsevier B.V. All rights reserved.

The ability to generate microorganisms that can produce biofuels similar to petroleum-based transportation fuels would allow the use of existing engines and infrastructure and would save an enormous amount of capital required for replacing the current infrastructure to accommodate biofuels that have properties significantly different from petroleum-based fuels. Several groups have demonstrated the feasibility of manipulating microbes to produce molecules similar to petroleum-derived products, albeit at relatively low productivity (e.g. maximum butanol production is around 20 g/L). For cost-effective production of biofuels, the fuel-producing hosts and pathways must be engineered and optimized. Advances in metabolic engineering and synthetic biology willmore » provide new tools for metabolic engineers to better understand how to rewire the cell in order to create the desired phenotypes for the production of economically viable biofuels.« less

The mandatory use of fluorescent lamps as part of a Brazilian energy-saving program generates a huge number of spent fluorescent lamps (SFLs). After operational life, SFLs cannot be disposed as common garbage owing to mercury and lead contamination. Recycling methods separate contaminated glass tubes and promote cleaning for reuse. In this work, glass from decontaminated SFLs was incorporated into clay ceramics, not only as an environmental solution for such glass wastes and clay mining reduction but also due to technical and economical advantages. Up to 30 wt.% of incorporation, a significant improvement in fired ceramic flexural strength and a decrease in water absorption was observed. A prospective analysis showed clay ceramic incorporation as an environmentally correct and technical alternative for recycling the enormous amount of SFLs disposed of in Brazil. This could also be a solution for other world clay ceramic producers, such as US, China and some European countries.

Passenger aircraft cabin air quality: trends, effects, societal costs, proposals.

Hocking, M B

2000-08-01

As aircraft operators have sought to substantially reduce propulsion fuel cost by flying at higher altitudes, the energy cost of providing adequate outside air for ventilation has increased. This has lead to a significant decrease in the amount of outside air provided to the passenger cabin, partly compensated for by recirculation of filtered cabin air. The purpose of this review paper is to assemble the available measured air quality data and some calculated estimates of the air quality for aircraft passenger cabins to highlight the trend of the last 25 years. The influence of filter efficiencies on air quality, and a few medically documented and anecdotal cases of illness transmission aboard aircraft are discussed. Cost information has been collected from the perspective of both the airlines and passengers. Suggestions for air quality improvement are given which should help to result in a net, multistakeholder savings and improved passenger comfort.

Analyzing effective municipal solid waste recycling programs: the case of county-level MSW recycling performance in Florida, USA.

Park, Seejeen; Berry, Frances S

2013-09-01

Municipal solid waste (MSW) recycling performance, both nationally and in Florida, USA, has shown little improvement during the past decade. This research examines variations in the MSW recycling program performance in Florida counties in an attempt to identify effective recycling programs. After reviewing trends in the MSW management literature, we conducted an empirical analysis using cross-sectional multiple regression analysis. The findings suggest that the convenience-based hypothesis was supported by showing that curbside recycling had a positive effect on MSW recycling performance. Financial (cost-saving) incentive-based hypotheses were partially supported meaning that individual level incentives can influence recycling performance. Citizen environmental concern was found to positively affect the amount of county recycling, while education and political affiliation yielded no significant results. In conclusion, this article discusses the implications of the findings for both academic research and practice of MSW recycling programs.

2017-11-01

High demand for cement in the concrete production has been increased which become the problems in the industry. Thus, this problem will increase the production cost of construction material and the demand for affordable houses. Moreover, the production of Portland cement leads to the release of a significant amount of CO2 and other gases leading to the effect on global warming. The need for a sustainable and green construction building material is required in the construction industry. Hence, this paper presents utilization of palm oil fuel ash and ceramic waste as partial cement replacement in the production of concrete. Using both of this waste in the concrete production would benefit in many ways. It is able to save cost and energy other than protecting the environment. In short, 20% usage of palm oil fuel ash and 30% replacement of ceramic waste as cement replacement show the acceptable and satisfactory strength of concrete.

Diagnostic needle arthroscopy and the economics of improved diagnostic accuracy: a cost analysis.

PubMed

Voigt, Jeffrey D; Mosier, Michael; Huber, Bryan

Hundreds of thousands of surgical arthroscopy procedures are performed annually in the United States (US) based on MRI findings. There are situations where these MRI findings are equivocal or indeterminate and because of this clinicians commonly perform the arthroscopy in order not to miss pathology. Recently, a less invasive needle arthroscopy system has been introduced that is commonly performed in the physician office setting and that may help improve the accuracy of diagnostic findings. This in turn may prevent unnecessary follow-on arthroscopy procedures from being performed. The purpose of this analysis is to determine whether the in-office diagnostic needle arthroscopy system can provide cost savings by reducing unnecessary follow on arthroscopy procedures. Data obtained from a recent trial and from a systematic review were used in comparing the accuracy of MRI and VisionScope needle arthroscopy (VSI) with standard arthroscopy (gold standard). The resultant false positive and false negative findings were then used to evaluate the costs of follow-on procedures. These differences were then modeled for the US patient population diagnosed and treated for meniscal knee pathology (most common disorder) to determine if a technology such as VSI could save the US healthcare system money. Data on surgical arthroscopy procedures in the US for meniscal knee pathology were used (calendar year [CY] 2010). The costs of performing diagnostic and surgical arthroscopy procedures (using CY 2013 Medicare reimbursement amounts), costs associated with false negative findings, and the costs for treating associated complications arising from diagnostic and therapeutic arthroscopy procedures were assessed. In patients presenting with medial meniscal pathology (International Classification of Diseases, 9th edition, Clinical Modification [ICD9CM] diagnosis 836.0), VSI in place of MRI (standard of care) resulted in a net cost savings to the US system of US$115-US$177 million (CY 2013) (use of systematic review and study data, respectively). In patients presenting with lateral meniscus pathology (ICD9CM 836.1), VSI in place of MRI cost the healthcare system an additional US$14-US$97 million (CY 2013). Overall aggregate savings for meniscal (lateral plus medial) pathology were identified in representative care models along with more appropriate care as fewer patients were exposed to higher risk surgical procedures. Since in-office arthroscopy is significantly more accurate, patients can be treated more appropriately and the US healthcare system can save money, most especially in medial meniscal pathology.

The application of rapid, specific, and sensitive methods for pathogen detection and quantification is very advantageous in diagnosis of human pathogens in several applications, including food analysis. The aim of this study was the evaluation of a method for the multiplexed detection and quantification of three significant foodborne pathogenic species (Escherichia coli O157, Salmonella spp., and Listeria monocytogenes). The assay combines specific DNA extraction by multiplex magnetic capture hybridization (mMCH) with multiplex real-time PCR. The amplification assay showed linearity in the range 10 6 -10 genomic units (GU)/PCR for each co-amplified species. The sensitivity corresponded to 1 GU/PCR for E. coli O157 and L. monocytogenes, and 10 GU/PCR for Salmonella spp. The immobilization process and the hybrid capture of the MCH showed good efficiency and reproducibility for all targets, allowing the combination in equal amounts of the different nanoparticle types in mMCH. MCH and mMCH efficiencies were similar. The detection limit of the method was 10 CFU in samples with individual pathogens and 10 2  CFU in samples with combination of the three pathogens in unequal amounts (amount's differences of 2 or 3 log). In conclusion, this multiplex molecular platform can be applied to determine the presence of target species in food samples after culture enrichment. In this way, this method could be a time-saving and sensitive tool to be used in routine diagnosis.

To characterize willingness to pay for private operations and preferred waiting time among patients awaiting cataract surgery in Hong Kong. This was a cross-sectional survey. Subjects randomly selected from cataract surgical waiting lists in Hong Kong (n = 467) underwent a telephone interview based on a structured, validated questionnaire. Data were collected on private insurance coverage, preferred waiting time, amount willing to pay for surgery, and self-reported visual function and health status. Among 300 subjects completing the interview, 144 (48.2%) were 76 years of age or older, 177 (59%) were women, and mean time waiting for surgery was 17 +/- 15 months. Among 220 subjects (73.3%) willing to pay anything for surgery, the mean amount was US$552 +/- 443. With adjustment for age, education, and monthly household income, subjects willing to pay anything were less willing to wait 12 months for surgery (OR = 4.34; P = 0.002), more likely to know someone having had cataract surgery (OR = 2.20; P = 0.03), and more likely to use their own savings to pay for the surgery (OR = 2.21; P = 0.04). Subjects considering private cataract surgery, knowing people who have had cataract surgery, using nongovernment sources to pay for surgery, and having lower visual function were willing to pay more. Many patients wait significant periods for cataract surgery in Hong Kong, and are willing to pay substantial amounts for private operations. These results may have implications for other countries with cataract waiting lists.

Freight Wing Incorporated utilized the opportunity presented by this DOE category one Inventions and Innovations grant to successfully research, develop, test, patent, market, and sell innovative fuel and emissions saving aerodynamic attachments for the trucking industry. A great deal of past scientific research has demonstrated that streamlining box shaped semi-trailers can significantly reduce a truck's fuel consumption. However, significant design challenges have prevented past concepts from meeting industry needs. Market research early in this project revealed the demands of truck fleet operators regarding aerodynamic attachments. Products must not only save fuel, but cannot interfere with the operation of the truck,more » require significant maintenance, add significant weight, and must be extremely durable. Furthermore, SAE/TMC J1321 tests performed by a respected independent laboratory are necessary for large fleets to even consider purchase. Freight Wing used this information to create a system of three practical aerodynamic attachments for the front, rear and undercarriage of standard semi trailers. SAE/TMC J1321 Type II tests preformed by the Transportation Research Center (TRC) demonstrated a 7% improvement to fuel economy with all three products. If Freight Wing is successful in its continued efforts to gain market penetration, the energy and environmental savings would be considerable. Each truck outfitted saves approximately 1,100 gallons of fuel every 100,000 miles, which prevents over 12 tons of CO2 from entering the atmosphere. If all applicable trailers used the technology, the country could save approximately 1.8 billion gallons of diesel fuel, 18 million tons of emissions and 3.6 billion dollars annually.« less

Cancer treatments have improved outcomes but access to medications is an issue around the world and especially so in low- and middle-income countries, such as India. Generic substitution may lead to significant cost savings. The author aimed to compare the cost and estimate potential cost savings per cycle, per patient, and for the country as a whole with generic substitution of frequently used chemotherapy drugs in the treatment of common cancers in India. Generic paclitaxel (Taxol), docetaxel (Taxotere), gemcitabine, oxaliplatin and irinotecan cost from 8.9% to 36% of their equivalent branded originator drug, resulting in cost savings of ~ Indian Rupees (INR) 11,000 to >INR 90,000 (USD 200-1600, Euro 160-1300) per cycle; and ~INR 50,000 to >INR 240,000 (USD 900-4300, Euro 700-3400) per patient. Overall, potential yearly savings for health systems in India were nearly INR 47 billion (~USD 843 million, Euro 670 million). In conclusion, generic substitution for frequently used chemotherapy drugs in the treatment of common cancers has an enormous potential to generate significant cost savings and increase access to cancer treatments in India and other low- and middle-income countries.

Continuous oxygen treatment is essential for managing children with hypoxemia, but access to oxygen in low-resource countries remains problematic. Given the high burden of pneumonia in these countries and the fact that flow can be gradually reduced as therapy progresses, oxygen conservation through routine titration warrants exploration. To determine the amount of oxygen saved via titration during oxygen therapy for children with hypoxemic pneumonia. Based on published clinical data, we developed a model of oxygen flow rates needed to manage hypoxemia, assuming recommended flow rate at start of therapy, and comparing total oxygen used with routine titration every 3 minutes or once every 24 hours versus no titration. Titration every 3 minutes or every 24 hours provided oxygen savings estimated at 11.7% ± 5.1% and 8.1% ± 5.1% (average ± standard error of the mean, n = 3), respectively. For every 100 patients, 44 or 30 kiloliters would be saved-equivalent to 733 or 500 hours at 1 liter per minute. Ongoing titration can conserve oxygen, even performed once-daily. While clinical validation is necessary, these findings could provide incentive for the routine use of pulse oximeters for patient management, as well as further development of automated systems.

Telemedicine can make healthcare greener.

The American healthcare industry is generally lacking environmentally sustainable practices. The environmental impact of healthcare practices in the country has been largely disregarded due to ambivalence, ignorance, and fears of additional costs and regulations. The current practices continue to pollute the environment by requiring large amounts of travel and paperwork by both the patient and the clinician. Telemedicine and health information technology help save time, energy, raw materials (such as paper and plastic), and fuel, thereby lowering the carbon footprint of the health industry. By implementing green practices, for instance, by engaging in carbon credit programs, the health industry could benefit financially as well as reduce its negative impact on the health of our planet. Companies that reduce their carbon emissions by implementing energy-saving practices can sell their carbon credits to companies that emit more carbon than permissible by their legally binding commitment. These carbon profits can then be used for healthcare research or to provide healthcare to the underserved. Alternatively, the savings could be used for green purchasing and to implement other carbon-reducing activities. This report reviews the numerous possible options for the American health industry to become greener and lower its carbon footprint while at the same time becoming more time- and cost efficient.

Steels with controlled hardenability for induction hardening

NASA Astrophysics Data System (ADS)

Shepelyakovskii, K. Z.

1980-07-01

Steels of the CH and LH type developed in the Soviet Union permit the use of a new method of induction hardening — bulk-surface hardening — and efficient utilization of the high-strength conditions (σb = 230-250 kgf/mm2). These steels make it possible to improve the structural strength, operating characteristics, service life, and reliability of critical heavily loaded machine parts. At the same time, CH steels make it possible to reduce by a factor of 2-3 the quantity of alloying elements, reduce the electrical energy for heat treatment, and completely exclude the cost of quenching oil for heat treatment in automatic equipment with high labor productivity, while retaining good working conditions. All this leads to substantial savings in production and operation. For example, when transmission gears (cylindrical and conical) are manufactured from LH steels the annual savings amount to more than 700,000 rubles at two automobile plants. Machine parts of CH steels — half axles and bearings in railway cars —have saved respectively six and four million rubles annually. The introduction of controlled-hardenability steels for induction hardening is a necessary condition for technological progress in machine construction and metallurgy.

N-ViroTech--a novel process for the treatment of nutrient limited wastewaters.

As pulp and paper wastewaters are mostly deficient in nitrogen and phosphorus, historical practice has dictated that they cannot be effectively treated using microbiological processes without the addition of supplementary nutrients, such as urea and phosphoric acid. Supplementation is a difficult step to manage efficiently, requiring extensive post-treatment monitoring and some degree of overdosing to ensure sufficient nutrient availability under all conditions. As a result, treated wastewaters usually contain excess amounts of both nutrients, leading to potential impacts on the receiving waters such as eutrophication. N-ViroTech is a highly effective alternative treatment technology which overcomes this nutrient deficiency/excess paradox. The process relies on communities of nitrogen-fixing bacteria, which are able to directly fix nitrogen from the atmosphere, thus satisfying their cellular nitrogen requirements. The process relies on manipulation of growth conditions within the biological system to maintain a nitrogen-fixing population whilst achieving target wastewater treatment performance. The technology has significant advantages over conventional activated sludge operation, including: Improved environmental performance. Nutrient loadings in the final treated effluent for selected nitrogen and phosphorus species (particularly ammonium and orthophosphate) may be reduced by over 90% compared to conventional systems; Elimination of nitrogen supplementation, and minimisation of phosphorus supplementation, thus achieving significant chemical savings and resulting in between 25% and 35% savings in operational costs for a typical system; Self-regulation of nutrient requirements, as the bacteria only use as much nitrogen as they require, allowing for substantially less operator intervention and monitoring. This paper will summarise critical performance outcomes of the N-ViroTech process utilising results from laboratory-, pilot-scale and recent alpha-adopter, full-scale trials.

Cost-effectiveness of adding granulocyte colony-stimulating factor to primary prophylaxis with antibiotics in small-cell lung cancer.

Recently, a Dutch, randomized, phase III trial demonstrated that, in small-cell lung cancer patients at risk of chemotherapy-induced febrile neutropenia (FN), the addition of granulocyte colony-stimulating factor (GCSF) to prophylactic antibiotics significantly reduced the incidence of FN in cycle 1 (24% v 10%; P = .01). We hypothesized that selecting patients at risk of FN might increase the cost-effectiveness of GCSF prophylaxis. Economic analysis was conducted alongside the clinical trial and was focused on the health care perspective. Primary outcome was the difference in mean total costs per patient in cycle 1 between both prophylactic strategies. Cost-effectiveness was expressed as costs per percent-FN-prevented. For the first cycle, the mean incremental costs of adding GCSF amounted to 681 euro (95% CI, -36 to 1,397 euro) per patient. For the entire treatment period, the mean incremental costs were substantial (5,123 euro; 95% CI, 3,908 to 6,337 euro), despite a significant reduction in the incidence of FN and related savings in medical care consumption. The incremental cost-effectiveness ratio was 50 euro per percent decrease of the probability of FN (95% CI, -2 to 433 euro) in cycle 1, and the acceptability for this willingness to pay was approximately 50%. Despite the selection of patients at risk of FN, the addition of GCSF to primary antibiotic prophylaxis did not result in cost savings. If policy makers are willing to pay 240 euro for each percent gain in effect (ie, 3,360 euro for a 14% reduction in FN), the addition of GCSF can be considered cost effective.

Rapid desensitization transiently prevents severe allergic reactions, allowing administration of life-saving therapies in previously sensitized patients. However, the mechanisms underlying successful rapid desensitization are not fully understood. We sought to investigate whether the mast cell (MC) is an important target of rapid desensitization in mice sensitized to exhibit IgE-dependent passive systemic anaphylaxis in vivo and to investigate the antigen specificity and underlying mechanisms of rapid desensitization in our mouse model. C57BL/6 mice (in vivo) or primary isolated C57BL/6 mouse peritoneal mast cells (PMCs; in vitro) were passively sensitized with antigen-specific anti-2,4-dinitrophenyl IgE, anti-ovalbumin IgE, or both. MCs were exposed over a short period of time to increasing amounts of antigen (2,4-dinitrophenyl-human serum albumin or ovalbumin) in the presence of extracellular calcium in vitro or by means of intravenous administration to sensitized mice in vivo before challenging the mice with or exposing the PMCs to optimal amounts of specific or irrelevant antigen. Rapidly exposing mice or PMCs to progressively increasing amounts of specific antigen inhibited the development of antigen-induced hypothermia in sensitized mice in vivo and inhibited antigen-induced PMC degranulation and prostaglandin D2 synthesis in vitro. Such MC hyporesponsiveness was induced antigen-specifically and was associated with a significant reduction in antigen-specific IgE levels on MC surfaces. Rapidly exposing MCs to progressively increasing amounts of antigen can both enhance the internalization of antigen-specific IgE on the MC surface and also desensitize these cells in an antigen-specific manner in vivo and in vitro.

Retirement counselors, financial service professionals, and retirement intervention specialists routinely emphasize the importance of developing clear goals for the future; however, few empirical studies have focused on the benefits of retirement goal setting. In the present study, the extent to which goal clarity and financial planning activities predict retirement savings practices was examined among 100 working adults. Path analysis techniques were used to test two competing models, both of which were designed to predict savings contributions. Findings provide support for the model in which retirement goal clarity is a significant predictor of planning practices, and planning, in turn, predicts savings tendencies. Two demographic variables-income and age-were also revealed to be important elements of the model, with income accounting for roughly half of the explained variance in savings contributions. The results of this study have implications for the development of age-based models of planning, as well as implications for retirement counselors and financial planners who advise workers on long-term saving strategies.

In 1999, the Blue Cross and Blue Shield Federal Employee Program (FEP) implemented a pilot disease management program to manage congestive heart failure (CHF) among members. The purpose of this project was to estimate the financial return on investment in the pilot CHF program, prior to a full program rollout. A cohort of 457 participants from the state of Maryland was matched to a cohort of 803 nonparticipants from a neighboring state where the CHF program was not offered. Each cohort was followed for 12 months before the program began and 12 months afterward. The outcome measures of primary interest were the differences over time in medical care expenditures paid by FEP and by all payers. Independent variables included indicators of program participation, type of heart disease, comorbidity measures, and demographics. From the perspective of the funding organization (FEP), the estimated return on investment for the pilot CHF disease management program was a savings of $1.08 in medical expenditure for every dollar spent on the program. Adding savings to other payers as well, the return on investment was a savings of $1.15 in medical expenditures per dollar spent on the program. The amount of savings depended upon CHF risk levels. The value of a pilot initiative and evaluation is that lessons for larger-scale efforts can be learned prior to full-scale rollout.

Purpose - Water scarcity will further stress on available water systems and decrease the security of water in many areas. Therefore, innovative methods to minimize industrial water usage and waste production are of paramount importance in the process of extending fresh water resources and happen to be the main life support systems in many arid regions of the world. This paper demonstrates that there are good opportunities for many industries to save water and decrease waste water in softening process by substituting traditional with echo-friendly methods. The patented puffing method is an eco-efficient and viable technology for water saving and waste reduction in lime softening process. Design/methodology/approach - Lime softening process (LSP) is a very sensitive process to chemical reactions. In addition, optimal monitoring not only results in minimizing sludge that must be disposed of but also it reduces the operating costs of water conditioning. Weakness of the current (regular) control of LSP based on chemical analysis has been demonstrated experimentally and compared with the eco-efficient puffing method. Findings - This paper demonstrates that there is a good opportunity for many industries to save water and decrease waste water in softening process by substituting traditional method with puffing method, a patented eco-efficient technology. Originality/value - Details of the required innovative works to minimize industrial water usage and waste production are outlined in this paper. Employing the novel puffing method for monitoring of lime softening process results in saving a considerable amount of water while reducing chemical sludge.

People's behaviors and intentions about healthy behaviors depend on their beliefs, values, and knowledge about the issue. Various models of health education are used in deter¬mining predictors of different healthy behaviors but their efficacy in cultural behaviors, such as water saving behaviors, are not studied. The study was conducted to explain water saving beha¬viors in Yazd, Iran on the basis of Health Belief Model and Reasoned Action Theory. The cross-sectional study used random cluster sampling to recruit 200 heads of households to collect the data. The survey questionnaire was tested for its content validity and reliability. Analysis of data included descriptive statistics, simple correlation, hierarchical multiple regression. Simple correlations between water saving behaviors and Reasoned Action Theory and Health Belief Model constructs were statistically significant. Health Belief Model and Reasoned Action Theory constructs explained 20.80% and 8.40% of the variances in water saving beha-viors, respectively. Perceived barriers were the strongest Predictor. Additionally, there was a sta¬tistically positive correlation between water saving behaviors and intention. In designing interventions aimed at water waste prevention, barriers of water saving behaviors should be addressed first, followed by people's attitude towards water saving. Health Belief Model constructs, with the exception of perceived severity and benefits, is more powerful than is Reasoned Action Theory in predicting water saving behavior and may be used as a framework for educational interventions aimed at improving water saving behaviors.

2017-02-01

The present study investigated the effect of dilemma type, framing, and number of saved lives on moral decision making. A total of 591 undergraduates, with a mean age of 20.56 (SD = 1.37) were randomly assigned to 12 groups on the basis of a grid of two dilemma types (the trolley problem or the footbridge dilemma) by three frames (positive, neutral, or negative frame) by two different numbers of workers (5 or 15 people). The main effects of dilemma type, frame, and number of saved workers were all significant. The interaction of dilemma type and number of saved workers and the interaction of the three independent factors were significant. Results indicated that moral judgment is affected by framing. Specifically, people were more inclined to utilitarianism in the positive or neutral frame and more inclined to intuitionism in the negative frame. Furthermore, this effect can be moderated by dilemma type and number of saved lives. Implications of our results are discussed.

Do hospital mergers reduce costs?

PubMed

Schmitt, Matt

2017-03-01

Proponents of hospital consolidation claim that mergers lead to significant cost savings, but there is little systematic evidence backing these claims. For a large sample of hospital mergers between 2000 and 2010, I estimate difference-in-differences models that compare cost trends at acquired hospitals to cost trends at hospitals whose ownership did not change. I find evidence of economically and statistically significant cost reductions at acquired hospitals. On average, acquired hospitals realize cost savings between 4 and 7 percent in the years following the acquisition. These results are robust to a variety of different control strategies, and do not appear to be easily explained by post-merger changes in service and/or patient mix. I then explore several extensions of the results to examine (a) whether the acquiring hospital/system realizes cost savings post-merger and (b) if cost savings depend on the size of the acquirer and/or the geographic overlap of the merging hospitals.

Little is known about the costs of safety. A literature review conducted for this study indicates there is a lack of survey-based research dealing with the effects of occupational health and safety (OHS) prevention costs. To close this gap in the literature, this study investigates the interwoven relationships between OHS prevention costs, employee satisfaction, OHS performance and accident costs. Data were collected from 159 OHS management system 18001-certified firms operating in Turkey and analyzed through structural equation modeling. The findings indicate that OHS prevention costs have a significant positive effect on safety performance, employee satisfaction and accident costs savings; employee satisfaction has a significant positive effect on accident costs savings; and occupational safety performance has a significant positive effect on employee satisfaction and accident costs savings. Also, the results indicate that safety performance and employee satisfaction leverage the relationship between prevention costs and accident costs.

The 2012 International Energy Conservation Code (IECC) yields positive benefits for Michigan homeowners. Moving to the 2012 IECC from the Michigan Uniform Energy Code is cost-effective over a 30-year life cycle. On average, Michigan homeowners will save $10,081 with the 2012 IECC. Each year, the reduction to energy bills will significantly exceed increased mortgage costs. After accounting for up-front costs and additional costs financed in the mortgage, homeowners should see net positive cash flows (i.e., cumulative savings exceeding cumulative cash outlays) in 1 year for the 2012 IECC. Average annual energy savings are $604 for the 2012 IECC.

It has been reported that students are already accumulating substantial debt from higher education fees and their spending habit are at a critical stage. These situations cause the youngsters facing bankruptcy if they cannot improve their saving habit. Many researches have acknowledged that the determinants of saving habit include financial management, parental socialization, peer influence, and self-control. However, there remains a need for investigating the relationship between these determinants in order to avoid bankruptcy among youngsters. The objectives of this study are to investigate the relationship between saving habit determinants and to generate a statistical model based on the determinants of saving habit. Data collection method used is questionnaire and its scope is undergraduate students of UiTM Negeri Sembilan, Kampus Seremban. Samples are chosen by using stratified probability sampling technique and cross-sectional method is used as the research design. The results are then analysed by using descriptive analysis, reliability test, Pearson Correlation, and Multiple Linear Regression analysis. It shows that saving habit and self-control has no relationship. It means that students with less self-control tend to save less. A statistical model has been generated that incorporated this relationship. This study is significant to help the students save more by having high self-control.

Should the next standby power target be 0-watt?

DOE Office of Scientific and Technical Information (OSTI.GOV)

Meier, Alan; Siderius, Hans-Paul

The standby power use of appliances continues to consume large amounts of electricity. Considerable success has been made in reducing each device’s use, but these savings have been offset by a huge increase in the number of products using standby power and new power requirements for maintaining network connections. Current strategies to reduce standby have limitations and may not be most appropriate for emerging energy consumption trends. A new strategy for further reductions in standby, the “Standzero” option, encourages electrical products to be designed to operate for short periods without relying on mains-supplied electricity. Energy savings are achieved through enhancedmore » efficiency and by harvesting ambient energy. A sensitivity analysis suggests many appliances could be designed to operate for at least an hour without relying on mains power and, in some cases, may be able to operate indefinitely at zero watts until activated.« less
