  2. BEPS redesign of 168 commercial buildings: summary report

    Stoops, J.L.; Deringer, J.J.; Moreno, S.; Misuriello, H.P.


    The objective of this report is to present, in usable form, summary data from the Building Energy Performance Standards (BEPS) Phase II commercial buildings energy research conducted in 1978-1979. Summary data presented were obtained from two major research efforts: the BEPS Phase II Redesign experiment; and the related research on ASHRAE Standard 90-75R. The bulk of this report consists of data tabulations of key energy parameters for the 168 sample buildings, which were tabulated from computer-stored files of the 1978-1979 data. Two kinds of tabulations are included: numerical tabulations that extracted information from the computer-stored data base for the 168 sample buildings; and graphic presentations of the computer-generated data, plus data extracted from other sources. The intent is to provide a single data compendium of key energy-related factors from the 1978 redesign experiment and the associated 1978-1979 ASHRAE Standard 90-75R research. This report also supplements the information for which there was not space in the magazine articles. Thus, for some building types, additional analysis, comments, and data tabulations are included that could not be included in the articles because space was limited. These additional analysis items are not consistent across building types because both the energy conservation opportunities and the design strategies applied by the building designers varied considerably by building type. The chapters have been entered individually into EDB and ERA.

  3. Commercial off-the-shelf consumer health informatics interventions: recommendations for their design, evaluation and redesign.

    Marquard, Jenna L; Zayas-Cabán, Teresa


    The goal of this paper is to describe the successful application of a use case-based evaluation approach to guide the effective design, evaluation and redesign of inexpensive, commercial, off-the-shelf consumer health informatics (CHI) interventions. Researchers developed four CHI intervention use cases representing two distinct patient populations (patients with diabetes with high blood pressure, post-bariatric surgery patients), two commercial off-the-shelf CHI applications (Microsoft HealthVault, Google Health), and related devices (blood pressure monitor, pedometer, weight scale). Three patient proxies tested each intervention for 10 days. The patient proxies recorded their challenges while completing use case tasks, rating the severity of each challenge based on how much it hindered their use of the intervention. Two independent evaluators categorized the challenges by human factors domain (physical, cognitive, macroergonomic). The use case-based approach resulted in the identification of 122 challenges, with 12% physical, 50% cognitive and 38% macroergonomic. Thirty-nine challenges (32%) were at least moderately severe. Nine of 22 use case tasks (41%) accounted for 72% of the challenges. The study used two patient proxies and addressed two specific patient populations and low-cost, off-the-shelf CHI interventions, which may not perfectly generalize to a larger number of proxies, actual patient populations, or other CHI interventions. CHI designers can employ the use case-based evaluation approach to assess the fit of a CHI intervention with patients' health work, in the context of their daily activities and environment, which would be difficult or impossible to evaluate by laboratory-based studies.

For that support to be effective it must reflect and attend to the needs of patients. Purpose: To explore the perspectives of adult type 1 diabetes patients on their current diabetes care in order to generate ideas for creating a new patient centered intensive insulin clinic. Methods: A multi-method approach was used, comprising: an observational exercise of current clinical care; three focus groups (n = 17; and a survey of service users (n = 419 to test the ideas generated from the observational exercise and focus groups (rating 1 to 5 in terms of importance. The ideas generated by the multi-method approach were organized thematically and mapped onto the Chronic Care Model (CCM. Results: The themes and preferences for service redesign in relation to CCM components were: health care organization, there was an interest in having enhanced systems for sharing clinical information; self-management support, patients would like more flexible and easy to access resources and more help with diabetes technology and psychosocial support; delivery system design and clinical information systems, the need for greater integration of care and better use of clinic time; productive relationships, participants would like more continuity; access to health professionals, patient involvement and care planning. The findings from the patient survey indicate high preferences for most of the areas for service

  8. Ergonomic redesign and evaluation of a clamping tool handle.

    Jung, Myung-Chul; Hallbeck, M Susan


    The handle of a commercial bar clamp was redesigned using ergonomic principles and then compared with an original clamp. Ten male and ten female students participated in simulated clamping tasks under various conditions, including different clamping heights, clamping methods, and handle-gripping methods, with respect to the dependent variables of clamping and handle-squeezing forces. The results showed that the redesigned clamp produced larger clamping force with lower handle-squeezing forces than the original clamp. As expected, males exerted more force than females in both clamping and squeezing forces. A pistol grip method was superior to an upside-down handle-gripping method. Two-handed operation was recommended for this type of clamp by simultaneously pulling the trigger and sliding the bar in order to initially tighten around objects. This study shows that the application of ergonomic guidelines increases the efficiency and usability of manual handtools.

  18. Miscellaneous equipment in commercial buildings: The inventory, utilization, and consumption by equipment type

    Pratt, R.G.; Williamson, M.A.; Richman, E.E.


    The nature of the miscellaneous equipment (devices other than permanently installed lighting and those used for space conditioning) in commercial buildings is diverse, comprising a wide variety of devices that are subject to varied patterns of use. This portion of the commercial load is frequently underestimated, and widely hypothesized to be growing. These properties make it a particularly difficult load to characterize for purposes of demand-side management. In the End-Use Load and Consumer Assessment Program (ELCAP), over 100 commercial sites in the Pacific Northwest have been metered at the end-use level for several years. Detailed inspections of the equipment in them have also been conducted. This paper describes how the ELCAP data have been used to estimate three fundamental properties of the various types of equipment in several classes of commercial buildings: (1) the installed capacity per unit floor area, (2) utilization of the equipment relative to the installed capacity, and (3) the resulting energy consumption by building type and for the Pacific Northwest commercial sector as a whole. Applications for the results include assessment of conservation potential, prediction of equipment loads from survey data, estimating equipment loads for energy audits, targeting of conservation technology development, and disaggregating building total or mixed end-use data. 4 tabs., refs.

  19. Improving flow patterns and spillage characteristics of a box-type commercial kitchen hood.

    Huang, Rong Fung; Chen, Jia-Kun; Han, Meng-Ji; Priyambodo, Yusuf


    A conventional box-type commercial kitchen hood and its improved version (termed the "IQV commercial kitchen hood") were studied using the laser-assisted smoke flow visualization technique and tracer-gas (sulfur hexafluoride) detection methods. The laser-assisted smoke flow visualization technique qualitatively revealed the flow field of the hood and the areas apt for leakages of hood containment. The tracer-gas concentration detection method measured the quantitative leakage levels of the hood containment. The oil mists that were generated in the conventional box-type commercial kitchen hood leaked significantly into the environment from the areas near the front edges of ceiling and side walls. Around these areas, the boundary-layer separation occurred, inducing highly unsteady and turbulent recirculating flow, and leading to spillages of hood containment due to inappropriate aerodynamic design at the front edges of the ceiling and side walls. The tracer-gas concentration measurements on the conventional box-type commercial kitchen hood showed that the sulfur hexafluoride concentrations detected at the hood face attained very large values on an order of magnitude about 10(3)-10(4) ppb. By combining the backward-offset narrow suction slot, deflection plates, and quarter-circular arcs at the hood entrance, the IQV commercial kitchen hood presented a flow field containing four backward-inclined cyclone flow structures. The oil mists generated by cooking were coherently confined in these upward-rising cyclone flow structures and finally exhausted through the narrow suction slot. The tracer-gas concentration measurements on the IQV commercial kitchen hood showed that the order of magnitude of the sulfur hexafluoride concentrations detected at the hood face is negligibly small--only about 10(0) ppb across the whole hood face.

  20. Computational redesign of endonuclease DNA binding and cleavage specificity

    Ashworth, Justin; Havranek, James J.; Duarte, Carlos M.; Sussman, Django; Monnat, Raymond J.; Stoddard, Barry L.; Baker, David


    The reprogramming of DNA-binding specificity is an important challenge for computational protein design that tests current understanding of protein-DNA recognition, and has considerable practical relevance for biotechnology and medicine. Here we describe the computational redesign of the cleavage specificity of the intron-encoded homing endonuclease I-MsoI using a physically realistic atomic-level forcefield. Using an in silico screen, we identified single base-pair substitutions predicted to disrupt binding by the wild-type enzyme, and then optimized the identities and conformations of clusters of amino acids around each of these unfavourable substitutions using Monte Carlo sampling. A redesigned enzyme that was predicted to display altered target site specificity, while maintaining wild-type binding affinity, was experimentally characterized. The redesigned enzyme binds and cleaves the redesigned recognition site ~10,000 times more effectively than does the wild-type enzyme, with a level of target discrimination comparable to the original endonuclease. Determination of the structure of the redesigned nuclease-recognition site complex by X-ray crystallography confirms the accuracy of the computationally predicted interface. These results suggest that computational protein design methods can have an important role in the creation of novel highly specific endonucleases for gene therapy and other applications.

  3. [Redesigning the hospital discharge process].

    Martínez-Ramos, M; Flores-Pardo, E; Uris-Sellés, J


    The aim of this article is to show that the redesign and planning process of hospital discharge advances the departure time of the patient from a hospital environment. Quasi-experimental study conducted from January 2011 to April 2013, in a local hospital. The cases analysed were from medical and surgical nursing units. The process was redesigned to coordinate all the professionals involved in the process. The hospital discharge improvement process improvement was carried out by forming a working group, the analysis of retrospective data, identifying areas for improvement, and its redesign. The dependent variable was the time of patient administrative discharge. The sample was classified as pre-intervention, inter-intervention, and post-intervention, depending on the time point of the study. The final sample included 14,788 patients after applying the inclusion and exclusion criteria. The mean discharge release time decreased significantly by 50 min between pre-intervention and post-intervention periods. The release time in patients with planned discharge was one hour and 25 min less than in patients with unplanned discharge. Process redesign is a useful strategy to improve the process of hospital discharge. Besides planning the discharge, it is shown that the patient leaving the hospital before 12 midday is a key factor.

  4. Redesigning an educational assessment program.

    Al Kadri, Hanan M F


    Changing educational assessment program represent a challenge to any organization. This change usually aims to achieve reliable and valid tests and assessment program that make a shift from individual assessment method to an integral program intertwined with the educational curriculum. This paper examines critically the recent developments in the assessment theory and practice, and establishes practical advices for redesigning educational assessment programs. Faculty development, availability of resources, administrative support, and competency based education are prerequisites to an effective successful change. Various elements should be considered when re-designing assessment program such as curriculum objectives, educational activities, standard settings, and program evaluation. Assessment programs should be part of the educational activities rather than being a separate objective on its own, linked to students' high quality learning.

  6. Creating outcomes with redesign efforts.

    Cole, D A


    Integrating principles from a variety of theories, managers have developed a conceptual framework for reengineering processes in an endoscopy unit to improve the value of services provided to customers. A major goal of this redesign was to enhance or maintain quality of care, increase efficiency, and maintain or reduce costs. This was accomplished by analyzing data and outcome measures related to patient, physician, and staff member satisfaction, as well as resource allocation. The departmental results were tangible, positive, and visible almost immediately. With the right team and the right techniques, tools, methodologies, and decision-making processes, redesign projects can and do lead to dramatic improvements in productivity, service, customer and staff member satisfaction, cost control, and innovation.

  7. Fluoride concentrations in three types of commercially packed tea drinks in Taiwan.

    Lung, Shih-Chun Candice; Hsiao, Pao-Kuei; Chiang, Kuang-Mao


    Tea is a popular drink around the world. It is also one of the major sources of fluoride intake. The objectives of this study were to assess fluoride concentrations in popular non-, semi-, and full-fermented tea drinks sold on the Taiwan market. Concentration differences among three types of commercially available tea drinks (tea leaf, tea bag, and packaged tea beverage) were explored. Several influential factors in intake concentrations were evaluated. The acute threshold intake (ATI) and allowable daily intake (ADI) of those tea drinks were also estimated. For each commercial type, samples from the most popular tea in one particular fermentation degree (non, semi, and full) were randomly purchased and analyzed for fluoride concentrations. Fluoride levels in different rounds of tea, in different containers, and with different ratios of water and tea leaf were also assessed. In total, 132 tea samples were analyzed. The mean fluoride concentrations in leaf tea without the first round, leaf tea with the first round, bagged tea, and packaged tea were 7.04, 7.79, 5.37, and 25.7 mg/l, respectively. Most of the intake concentrations in those samples exceeded 4 mg/l F, the lower bound of fluoride levels reported in the literatures to be associated with a lower IQ in children and a higher risk of bone fracture. Fluoride concentrations in packaged tea were the highest among the three types of commercially available tea. For studied leaf and bagged tea, almost a constant amount of fluoride was infused from the same amount of tea leaf regardless of the water volume. Besides this, making tea with glass or pottery tea makers would not affect fluoride intake concentrations. Acute intoxication is unlikely to occur. However, tea lovers in high fluoride content areas shall consider limit their consumption of tea drinks to avoid potential chronic effects.

  8. Redesigned Human Metabolic Simulator

    Duffield, Bruce; Jeng, Frank; Lange, Kevin


    A design has been formulated for a proposed improved version of an apparatus that simulates atmospheric effects of human respiration by introducing controlled amounts of carbon dioxide, water vapor, and heat into the air. Denoted a human metabolic simulator (HMS), the apparatus is used for testing life-support equipment when human test subjects are not available. The prior version of the HMS, to be replaced, was designed to simulate the respiratory effects of as many as four persons. It exploits the catalytic combustion of methyl acetate, for which the respiratory quotient (the molar ratio of carbon dioxide produced to oxygen consumed) is very close to the human respiratory quotient of about 0.86. The design of the improved HMS provides for simulation of the respiratory effects of as many as eight persons at various levels of activity. The design would also increase safety by eliminating the use of combustion. The improved HMS (see figure) would include a computer that would exert overall control. The computer would calculate the required amounts of oxygen removal, carbon dioxide addition, water addition, and heat addition by use of empirical equations for metabolic profiles of respiration and heat. A blower would circulate air between the HMS and a chamber containing a life-support system to be tested. With the help of feedback from a mass flowmeter, the blower speed would be adjusted to regulate the rate of flow according to the number of persons to be simulated and to a temperature-regulation requirement (the air temperature would indirectly depend on the rate of flow, among other parameters). Oxygen would be removed from the circulating air by means of a commercially available molecular sieve configured as an oxygen concentrator. Oxygen, argon, and trace amounts of nitrogen would pass through a bed in the molecular sieve while carbon dioxide, the majority of nitrogen, and other trace gases would be trapped by the bed and subsequently returned to the chamber.

  9. Commercial alumina templates as base to fabricate 123-type high-T{sub c} superconductor nanowires

    Koblischka, M.R.; Zeng, X.L.; Hartmann, U. [Institute of Experimental Physics, Saarland University, P. O. Box 151150, 66041 Saarbruecken (Germany)


    Nanowires of high-T{sub c} superconductors of the RE-123 type (RE = rare earths) were grown by the anodized alumina template method, employing commercially available alumina templates with nominal pore diameters of 20 and 100 nm. Pre-reacted YBa{sub 2}Cu{sub 3}O{sub x} (YBCO) and NdBa{sub 2}Cu{sub 3}O{sub x} (NdBCO) powder was molten on top of the templates in order to fill the pores with the 123-type material. The resulting samples were oxygen-annealed at 450 C. Superconductivity with a transition temperature of 88 K (YBCO) and 96 K (NdBCO) was confirmed by means of magnetic susceptibility measurements (SQUID) using pieces of the filled template. The electric (resistance) and magnetic measurements revealed further relatively sharp superconducting transitions. To understand the dimensions of the resulting nanowires (length up to 10 μm, diameter between 100 and 250 nm), which do not correspond to the nominal pore diameters, the empty and filled commercial templates were analyzed in detail by scanning electron microscopy. We discuss the feasibility of this approach to produce larger amounts of nanowires. (copyright 2015 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

  10. Intermittent redesign of continuous controllers

    Gawthrop, Peter J.; Wang, Liuping


    The reverse-engineering idea developed by Maciejowski in the context of model-based predictive control is applied to the redesign of continuous-time compensators as intermittent controllers. Not only does this give a way of designing constrained input and state versions of continuous-time compensators but also provides a method for turning continuous-time compensators into event-driven versions. The procedure is illustrated by three examples: an event-driven PID controller relevant to the human balance control problem, a constrained version of the classical mechanical vibration absorber of den Hartog and an event driven and constrained vibration absorber.

  15. Relationships among slurry characteristics and gaseous emissions at different types of commercial Spanish pig farms

    Becaccia, A.; Ferrer, P.; Ibañez, M.A.; Estellés, F.; Rodríguez, C.; Moset, V.; Blas, C. de; Calvet, P.; García-Rebollar, P.


    This study aimed to analyse several factors of variation of slurry composition and to establish prediction equations for potential methane (CH4) and ammonia (NH3) emissions. Seventy-nine feed and slurry samples were collected at two seasons (summer and winter) from commercial pig farms sited at two Spanish regions (Centre and Mediterranean). Nursery, growing-fattening, gestating and lactating facilities were sampled. Feed and slurry composition were determined, and potential CH4 and NH3 emissions measured at laboratory. Feed nutrient contents were used as covariates in the analysis. Near infrared reflectance spectroscopy (NIRS) was evaluated as a predicting tool for slurry composition and potential gaseous emissions. A wide variability was found both in feed and slurry composition. Mediterranean farms had a higher pH (p<0.001) and ash (p=0.02) concentration than those located at the Centre of Spain. Also, type of farm affected ether extract content of the slurry (p=0.02), with highest values obtained for the youngest animal facilities. Results suggested a buffer effect of dietary fibre on slurry pH and a direct relationship (p<0.05) with fibre constituents of manure. Dietary protein content did not affect slurry nitrogen content but decreased (p=0.003) total and volatile solids concentration. Prediction models of potential NH3 emissions (R2=0.89) and CH4 yield (R2=0.61) were obtained from slurry composition. Predictions from NIRS showed a high accuracy for most slurry constituents (R2>0.90) and similar accuracy of prediction of potential NH3 and CH4 emissions (R2=0.84 and 0.68, respectively) to models using slurry characteristics, which can be of interest to estimate emissions from commercial farms and establish mitigation strategies or optimize biogas production.

  17. Curriculum Redesign in Veterinary Medicine: Part II.

    Macik, Maria L; Chaney, Kristin P; Turner, Jacqueline S; Rogers, Kenita S; Scallan, Elizabeth M; Korich, Jodi A; Fowler, Debra; Keefe, Lisa M


    Curricular review is considered a necessary component for growth and enhancement of academic programs and requires time, energy, creativity, and persistence from both faculty and administration. On a larger scale, a comprehensive redesign effort involves forming a dedicated faculty redesign team, developing program learning outcomes, mapping the existing curriculum, and reviewing the curriculum in light of collected stakeholder data. The faculty of the Texas A&M University College of Veterinary Medicine & Biomedical Sciences (TAMU) recently embarked on a comprehensive curriculum redesign effort through partnership with the university's Center for Teaching Excellence. Using a previously developed evidence-based model of program redesign, TAMU created a process for use in veterinary medical education, which is described in detail in the first part of this article series. An additional component of the redesign process that is understated, yet vital for success, is faculty buy-in and support. Without faculty engagement, implementation of data-driven curricular changes stemming from program evaluation may be challenging.

    Börner, M.; Friesen, A.; Grützke, M.; Stenzel, Y. P.; Brunklaus, G.; Haetge, J.; Nowak, S.; Schappacher, F. M.; Winter, M.


    Established safety of lithium ion batteries is key for the vast diversity of applications. The influence of aging on the thermal stability of individual cell components and complete cells is of particular interest. Commercial 18650-type lithium ion batteries based on LiNi0.5Co0.2Mn0.3O2/C are investigated after cycling at different temperatures. The variations in the electrochemical performance are mainly attributed to aging effects on the anode side considering the formation of an effective solid-electrolyte interphase (SEI) during cycling at 45 °C and a thick decomposition layer on the anode surface at 20 °C. The thermal stability of the anodes is investigated including the analysis of the evolving gases which confirmed the severe degradation of the electrolyte and active material during cycling at 20 °C. In addition, the presence of metallic lithium deposits could strongly affect the thermal stability. Thermal safety tests using quasi-adiabatic conditions show variations in the cells response to elevated temperatures according to the state-of-charge, i.e. a reduced reactivity in the discharged state. Furthermore, it is revealed that the onset of exothermic reactions correlates with the thermal stability of the SEI, while the thermal runaway is mainly attributed to the decomposition of the cathode and the subsequent reactions with the electrolyte.

    Littek, Wolfgang; Heisig, Ulrich


    Deskilling of commercial and technical occupations in West Germany during the 1960s and 1970s was apparently a short-lived phenomenon. Since the 1970s, employers have adopted a skill-based modernization policy. Skilled administrative workers have used their qualifications as a means of influencing the process of work redesign. (SK)

  20. Job redesign and the health care manager.

    Layman, Elizabeth J


    Health care supervisors and managers are often asked to redesign jobs in their departments. Frequently, little information accompanies the directive. This article lists sources of change in work and defines key terms. Also reviewed are factors that supervisors and managers can weigh in their redesigns. The article suggests actions aligned to common problems in the work environment. Finally, guidelines for a practical, step-by-step approach are provided. For health care supervisors and managers, the key to a successful job redesign is to achieve the unique balance of factors that matches the situation.

  1. Comparison of p-type commercial electron diodes for in vivo dosimetry.

    Marre, D; Marinello, G


    This paper compares the characteristics of three types of commercial p-type electron diodes specially designed for in vivo dosimetry (Scanditronix EDD2, Sun Nuclear QED 111200-0 and PTW T60010E diodes coupled with a Therados DPD510 dosimeter) in electron fields with energies from 4.5 to 21 MeV, and in conditions similar to those encountered in radiotherapy. In addition to the diodes, a NACP plane parallel ionization chamber and film dosimeters have been used in the experiments. The influence of beam direction on the diode responses (directional effect) was investigated. It was found to be the greatest for the lowest electron beam energy. At 12 MeV and an incidence of +/- 30 degrees, the variation was found to be less than 1% for the Scanditronix and Sun Nuclear diodes and less than 3% for the PTW one. The three diodes exhibited a variation in sensitivity with dose-per-pulse of less than 1% over the range 0.18-0.43 mGy/pulse. The temperature dependence was also studied. The response was linear for the three diodes between 22.2 and 40 degrees C and the sensitivity variations with temperature were (0.25+/-0.01)%/degree C, (0.28+/-0.01)%/degree C, and (0.02 +/-0.01)%/degree C for Scanditronix, Sun Nuclear, and PTW diodes, respectively. Finally the perturbation to the irradiation field induced by the presence of diodes placed at the surface of a homogeneous phantom was investigated and found to be significant, both at the surface and at the depth of maximum dose (several tens of percent) for all three diode types. There is an increase of dose right underneath the diode (close to the surface) and a dose shadow at the depth of maximum. The study shows that electron diodes can be used for in vivo dosimetry provided their characteristics are carefully established before use and taken into consideration at the time of interpretation of the results.

  2. Target selection by natural and redesigned PUF proteins.

    Porter, Douglas F; Koh, Yvonne Y; VanVeller, Brett; Raines, Ronald T; Wickens, Marvin


    Pumilio/fem-3 mRNA binding factor (PUF) proteins bind RNA with sequence specificity and modularity, and have become exemplary scaffolds in the reengineering of new RNA specificities. Here, we report the in vivo RNA binding sites of wild-type (WT) and reengineered forms of the PUF protein Saccharomyces cerevisiae Puf2p across the transcriptome. Puf2p defines an ancient protein family present throughout fungi, with divergent and distinctive PUF RNA binding domains, RNA-recognition motifs (RRMs), and prion regions. We identify sites in RNA bound to Puf2p in vivo by using two forms of UV cross-linking followed by immunopurification. The protein specifically binds more than 1,000 mRNAs, which contain multiple iterations of UAAU-binding elements. Regions outside the PUF domain, including the RRM, enhance discrimination among targets. Compensatory mutants reveal that one Puf2p molecule binds one UAAU sequence, and align the protein with the RNA site. Based on this architecture, we redesign Puf2p to bind UAAG and identify the targets of this reengineered PUF in vivo. The mutant protein finds its target site in 1,800 RNAs and yields a novel RNA network with a dramatic redistribution of binding elements. The mutant protein exhibits even greater RNA specificity than wild type. The redesigned protein decreases the abundance of RNAs in its redesigned network. These results suggest that reengineering using the PUF scaffold redirects and can even enhance specificity in vivo.

  5. Redesigning training for internal medicine.

    Weinberger, Steven E; Smith, Lawrence G; Collier, Virginia U


    The American College of Physicians supports the need for reform throughout the continuum of training in internal medicine. Today's internists must have the necessary knowledge, skills, and attitudes to meet the challenges of an expanding body of medical knowledge and a rapidly evolving system of health care delivery. Suggested priorities for undergraduate medical education include redesigning curricular experiences to afford students earlier and more exposure to career opportunities in internal medicine, improving ambulatory education, exposing students to outstanding faculty role models in internal medicine, and incorporating educational experiences during the fourth year that optimize its value and relevance to the student's future career plans in internal medicine. Internal medicine residency training should remain a 3-year experience, with a component of core education common to all trainees and a component of customized training in the third year targeted toward the resident's career goals. Residency programs should be designed around educational rather than institutional service needs. The ambulatory component of training requires substantial reform in its structure, sites, content, and timing. Team-based models should be used both for patient care and for flexibility in design of residency training. Better faculty models must be developed that build on the concept of a "core faculty," improve the rewards for teaching faculty, and provide appropriate faculty development focusing on a necessary set of educator competencies.

  6. Types of fruits and vegetables used in commercial baby foods and their contribution to sugar content.

    Garcia, Ada Lizbeth; McLean, Kimberley; Wright, Charlotte M


    Fruits and vegetables (F&V) are often featured in names of commercial baby foods (CBFs). We aimed to survey all available CBFs in the UK market with F&V included in the food name in order to describe the amount and types of F&V used in CBF and their contribution to total sugar content. Food labels were used to identify F&V and total sugar content. Fruits were more common than vegetables in names of the 329 CBFs identified. The six most common F&V in the names were all relatively sweet: apple, banana, tomato, mango, carrot and sweet potato. The percentage of F&V in the foods ranged from a median of 94% for sweet-spoonable to 13% for dry-savoury products. Fruit content of sweet foods (n = 177) was higher than vegetable content of savoury foods (n = 152) with a median (IQR) of 64.0 g/100 g (33.0-100.0) vs. 46.0 g/100 g (33-56.7). Fruit juice was added to 18% of products. The proportion of F&V in CBF correlated significantly with sugar content for all the food types except dry-savoury food (sweet-spoonable r = 0.24, P = 0.006; savoury-spoonable r = 0.65, P < 0.001; sweet-dry r = 0.81, P < 0.001; savoury-dry r = 0.51, P = 0.06) and explained up to two-thirds of the variation in sugar content. The F&V content of CBFs mainly consists of fruits and relatively sweet vegetables which are unlikely to encourage preferences for bitter-tasting vegetables or other non-sweet foods. F&V contribute significantly to the total sugar content, particularly of savoury foods.

  7. Ergonomic Redesign of an Industrial Control Panel

    S Raeisi


    Full Text Available Operator's role in industrial control centers takes place in time, which is one of the most important determinants of whether an expected action is going to be successful or not. In certain situations, due to the complex nature of the work, the existing interfaces and already prepared procedures do not meet the dynamic requirements of operator's cognitive demands, making the control tasks unnecessarily difficult. This study was conducted to identify ergonomic issues with a specific industrial control panel, and redesign its layout and elements to enhance its usability. Task and link analysis methodologies were implemented. All essential functions and supporting operations were identified at the required trivial levels. Next, the weight of any possible link between the elements of the panel was computed as a composite index of frequency and importance. Finally, all components were rearranged within a new layout, and a computerized mockup was generated. A total of 8 primary tasks was identified, including 4 system failure handling tasks, switching between manual and automated modes, and 3 types of routine vigilance and control tasks. These tasks were broken down into 28 functions and 145 supporting operations, accordingly. Higher link values were observed between hand rest position and 2 elements. Also, 6 other components showed robust linkages. In conclusion, computer modeling can reduce the likelihood of accidents and near misses in industrial control rooms by considering the operators' misperception or mental burden and correcting poor design of the panels and inappropriate task allocation.

  9. Microbiological characteristics of four ‘chorizo’ types commercialized in Hidalgo State, Mexico

    Roberto Gonzalez-Tenorio


    Full Text Available Chorizo is a raw sausage commercialized in almost all Mexico, mainly in the central region. Chorizo is elaborated from small producers’ craftsman who sold their products in local markets, to big meat processors who distribute their products in supermarkets. These differences in elaboration affect chorizo quality. In this work commercial chorizo bought in four different points (local butchers, rural markets, supermarkets and supply centers. Mainly microbiological groups were determined. Techno-sanitary conditions regulation should be improved in order to establish quality criteria.

  10. Healthcare redesign: meaning, origins and application.

    Locock, L


    Healthcare organisations are using redesign to tackle variation in the quality of care and improve public satisfaction. It is represented as a radical challenge to traditional assumptions and practices which involves thinking through the best process to achieve speedy and effective patient care, identifying delays, unnecessary steps, or potential for error, and redesigning the process to improve the quality of care. This paper explores the meaning of redesign using practical illustrations. It examines its theoretical origins, particularly total quality management (TQM)/continuous quality improvement (CQI) and re-engineering, and assesses evidence which may inform its application. This evidence suggests that clinical ownership and senior management support will be essential. Redesign seeks to balance the more gradual approach of TQM with the organisation-wide lateral thinking of re-engineering. An incremental negotiated approach seems more likely to ensure clinical ownership, but carries a risk that QI will remain small scale with little impact on the wider organisation. Inclusion of some re-engineering techniques may help to overcome this difficulty. Evidence suggests that most QI techniques achieve only partial success. This may pose difficulties for redesign, which has generated high political expectations that it can solve long term problems in health care.

  11. Course Redesign: An Evidence-Based Approach

    Kathy Nomme


    Full Text Available A first year non-majors biology course, with an enrollment of around 440 students, has been redesigned from a course of traditional content and teaching style to one that emphasizes biological concepts in current global issues and incorporates active learning strategies. We were informed by the education literature incorporating many aspects of established curriculum redesign principles and extended its application to a biology course. Systematic measurement of student attitudes and collection of student feedback through a series of surveys as well as focus group interviews proved to be invaluable in the course redesign process. The information gathered over a two-year period enabled us to fine-tune the course content and teaching strategies effectively to better meet the interests of students in the non-majors course as was documented by the evidence gathered in this research.

  12. Development and Commercial Application of DZC Ⅱ-1 Type Catalyst for Hydrogenation of Pyrolysis Gasoline

    Zhao Ye; Wang Fucun


    Commercial application of the DZC Ⅱ-1 catalyst developed on the basis of the DZ-1 catalyst was introduced. The application tests of the catalyst under overload had proved that this catalyst demon-strated satisfactory adaptability to feedstock after continued operation for 20 months with little changes in the bed pressure drop, the reactor inlet temperature and the bed temperature rise. The DZC Ⅱ-1 catalyst was regarded as the best catalyst for the second-stage hydrogenation of pyrolysis gasoline.

  13. Ergonomic redesign of the electric guitar.

    Marmaras, N; Zarboutis, N


    The present study deals with the redesign of the electric guitar, considering ergonomic criteria. Difficulties met by novice musicians, neuro-muscular fatigue caused by guitar playing and occupational diseases occurring to professional guitarists, justify this study. Characteristics of existing electric guitar models which add to musician's fatigue or difficulty, were identified. A number of ergonomic requirements were then derived. The redesign process tried to satisfy these requirements, considering at the same time musical requirements and technical constraints. A comparative evaluation of the designed ergonomic guitar with three existing electric guitar models, showed that although the designed electric guitar preserves the main features of the instrument, it achieves better user fit.

  14. A strategic planning methodology for aircraft redesign

    Romli, Fairuz Izzuddin

    Due to a progressive market shift to a customer-driven environment, the influence of engineering changes on the product's market success is becoming more prominent. This situation affects many long lead-time product industries including aircraft manufacturing. Derivative development has been the key strategy for many aircraft manufacturers to survive the competitive market and this trend is expected to continue in the future. Within this environment of design adaptation and variation, the main market advantages are often gained by the fastest aircraft manufacturers to develop and produce their range of market offerings without any costly mistakes. This realization creates an emphasis on the efficiency of the redesign process, particularly on the handling of engineering changes. However, most activities involved in the redesign process are supported either inefficiently or not at all by the current design methods and tools, primarily because they have been mostly developed to improve original product development. In view of this, the main goal of this research is to propose an aircraft redesign methodology that will act as a decision-making aid for aircraft designers in the change implementation planning of derivative developments. The proposed method, known as Strategic Planning of Engineering Changes (SPEC), combines the key elements of the product redesign planning and change management processes. Its application is aimed at reducing the redesign risks of derivative aircraft development, improving the detection of possible change effects propagation, increasing the efficiency of the change implementation planning and also reducing the costs and the time delays due to the redesign process. To address these challenges, four research areas have been identified: baseline assessment, change propagation prediction, change impact analysis and change implementation planning. Based on the established requirements for the redesign planning process, several methods and

  15. Relationships among slurry characteristics and gaseous emissions at different types of commercial Spanish pig farms

    Amanda Beccaccia


    Full Text Available This study aimed to analyse several factors of variation of slurry composition and to establish prediction equations for potential methane (CH4 and ammonia (NH3 emissions. Seventy-nine feed and slurry samples were collected at two seasons (summer and winter from commercial pig farms sited at two Spanish regions (Centre and Mediterranean. Nursery, growing-fattening, gestating and lactating facilities were sampled. Feed and slurry composition were determined, and potential CH4 and NH3 emissions measured at laboratory. Feed nutrient contents were used as covariates in the analysis. Near infrared reflectance spectroscopy (NIRS was evaluated as a predicting tool for slurry composition and potential gaseous emissions. A wide variability was found both in feed and slurry composition. Mediterranean farms had a higher pH (p0.90 and similar accuracy of prediction of potential NH3 and CH4 emissions (R2=0.84 and 0.68, respectively to models using slurry characteristics, which can be of interest to estimate emissions from commercial farms and establish mitigation strategies or optimize biogas production.

  16. Species specificities among primates probed with commercially available fluorescence-based multiplex PCR typing kits.

    Hiroshige, Yuuji; Ohtaki, Hiroyuki; Yoshimoto, Takashi; Ogawa, Hisae; Ishii, Akira; Yamamoto, Toshimichi


    To assess species specificities among primates of signals from short tandem repeat (STR) loci included in two commercially available kits, mainly the AmpFlSTR Identifiler kit and additionally the GenePrint PowerPlex 16 system, we analyzed 69 DNA samples from 22 nonhuman primate species representing apes, Old World Monkeys (OWMs), New World Monkeys (NWMs), and prosimians. Each prosimian species and the NWM cotton-top tamarin apparently lacked all STR loci probed. Only one peak, the amelogenin-X peak, was evident in samples from all other NWMs, except the owl monkey. In contrast, several loci, including the amelogenin-X peak, was evident in samples from each OWM species. Notably, for each ape sample, the amelogenin peaks were concordant with morphological gender of the individual. Among the primates, especially in apes, the numbers of alleles for STR loci were increasing according to their phylogenetic order: prosimiansprimates for a few commercially released multiplex STR kits examined in this study would contribute to forensic examinations.

  17. Deactivation and Regeneration of Commercial Type Fischer-Tropsch Co-Catalysts—A Mini-Review

    Erling Rytter


    Full Text Available Deactivation of commercially relevant cobalt catalysts for Low Temperature Fischer-Tropsch (LTFT synthesis is discussed with a focus on the two main long-term deactivation mechanisms proposed: Carbon deposits covering the catalytic surface and re-oxidation of the cobalt metal. There is a great variety in commercial, demonstration or pilot LTFT operations in terms of reactor systems employed, catalyst formulations and process conditions. Lack of sufficient data makes it difficult to correlate the deactivation mechanism with the actual process and catalyst design. It is well known that long term catalyst deactivation is sensitive to the conditions the actual catalyst experiences in the reactor. Therefore, great care should be taken during start-up, shutdown and upsets to monitor and control process variables such as reactant concentrations, pressure and temperature which greatly affect deactivation mechanism and rate. Nevertheless, evidence so far shows that carbon deposition is the main long-term deactivation mechanism for most LTFT operations. It is intriguing that some reports indicate a low deactivation rate for multi-channel micro-reactors. In situ rejuvenation and regeneration of Co catalysts are economically necessary for extending their life to several years. The review covers information from open sources, but with a particular focus on patent literature.

  18. Effect of the addition of different types of oenological commercial tannins on phenolic and sensorial red wine characteristics evolution

    Jordão António M.


    Full Text Available The main objective of this work was to understand the effect of the addition of different commercial types of oenological tannins on red wine phenolic compounds and sensorial characteristics evolution. So, six different commercial oenological tannins obtained from different sources at an average dosage recommended by the manufactures were added to a red wine. During 120 wine aging days several phenolic parameters were analyzed (including several individual phenolic compounds by HPLC and also the sensorial characteristics of the wines. Wines treated with oenological tannins showed higher total phenols and flavonoid phenols and lesser color degradation during the aging time considered. After 120 aging days, wines aged with oenological tannins showed more total and individual anthocyanins and significantly more red color that induced significantly color differences in relation to the untreated wine (especially for the wines treated with condensed tannins. From a sensorial point of view it was also possible to detect a clear differentiation between the wines.

  3. Curriculum Redesign in Veterinary Medicine: Part I.

    Chaney, Kristin P; Macik, Maria L; Turner, Jacqueline S; Korich, Jodi A; Rogers, Kenita S; Fowler, Debra; Scallan, Elizabeth M; Keefe, Lisa M


    Curricular review is considered a necessary component for growth and enhancement of academic programs and requires time, energy, creativity, and persistence from both faculty and administration. At Texas A&M College of Veterinary Medicine & Biomedical Sciences (TAMU), the faculty and administration partnered with the university's Center for Teaching Excellence to create a faculty-driven, data-enhanced curricular redesign process. The 8-step process begins with the formation of a dedicated faculty curriculum design team to drive the redesign process and to support the college curriculum committee. The next steps include defining graduate outcomes and mapping the current curriculum to identify gaps and redundancies across the curriculum. Data are collected from internal and external stakeholders including veterinary students, faculty, alumni, and employers of graduates. Data collected through curriculum mapping and stakeholder engagement substantiate the curriculum redesign. The guidelines, supporting documents, and 8-step process developed at TAMU are provided to assist other veterinary schools in successful curricular redesign. This is the first of a two-part report that provides the background, context, and description of the process for charting the course for curricular change. The process involves defining expected learning outcomes for new graduates, conducting a curriculum mapping exercise, and collecting stakeholder data for curricular evaluation (steps 1-4). The second part of the report describes the development of rubrics that were applied to the graduate learning outcomes (steps 5-8) and engagement of faculty during the implementation phases of data-driven curriculum change.

  5. Redesigning care at the Flinders Medical Centre: clinical process redesign using "lean thinking".

    Ben-Tovim, David I; Bassham, Jane E; Bennett, Denise M; Dougherty, Melissa L; Martin, Margaret A; O'Neill, Susan J; Sincock, Jackie L; Szwarcbord, Michael G


    *The Flinders Medical Centre (FMC) Redesigning Care program began in November 2003; it is a hospital-wide process improvement program applying an approach called "lean thinking" (developed in the manufacturing sector) to health care. *To date, the FMC has involved hundreds of staff from all areas of the hospital in a wide variety of process redesign activities. *The initial focus of the program was on improving the flow of patients through the emergency department, but the program quickly spread to involve the redesign of managing medical and surgical patients throughout the hospital, and to improving major support services. *The program has fallen into three main phases, each of which is described in this article: "getting the knowledge"; "stabilising high-volume flows"; and "standardising and sustaining". *Results to date show that the Redesigning Care program has enabled the hospital to provide safer and more accessible care during a period of growth in demand.

    Background On 7 and 11 July 2007, health officials in Texas and Indiana, respectively, reported 4 possible cases of type A foodborne botulism to the US Centers for Disease Control and Prevention. Foodborne botulism is a rare and sometimes fatal illness caused by consuming foods containing botulinum neurotoxin. Methods Investigators reviewed patients’ medical charts and food histories. Clinical specimens and food samples were tested for botulinum toxin and neurotoxin-producing Clostridium species. Investigators conducted inspections of the cannery that produced the implicated product. Results Eight confirmed outbreak associated cases were identified from Indiana (n = 2), Texas (n = 3), and Ohio (n = 3). Botulinum toxin type A was identified in leftover chili sauce consumed by the Indiana patients and 1 of the Ohio patients. Cannery inspectors found violations of federal canned-food regulations that could have led to survival of Clostridium botulinum spores during sterilization. The company recalled 39 million cans of chili. Following the outbreak, the US Food and Drug Administration inspected other canneries with similar canning systems and issued warnings to the industry about the danger of C. botulinum and the importance of compliance with canned food manufacturing regulations. Conclusions Commercially produced hot dog chili sauce caused these cases of type A botulism. This is the first US foodborne botulism outbreak involving a commercial cannery in >30 years. Sharing of epidemiologic and laboratory findings allowed for the rapid identification of implicated food items and swift removal of potentially deadly products from the market by US food regulatory authorities.

  9. Effective healthcare process redesign through an interdisciplinary team approach.

    Snyder, Rita; Huynh, Nathan; Cai, Bo; Vidal, José; Bennett, Kevin


    Healthcare process redesign is a complex and often high risk undertaking. Typically, there is a limited understanding of the baseline process and often inadequate tools by which to assess it. This can be confounded by narrow redesign team expertise that can result in unanticipated and/or unintended redesign consequences. Interdisciplinary research teams of healthcare, biostatistics, engineering and computer science experts provide broad support for a more effective and safer approach to healthcare process redesign. We describe an interdisciplinary research team focused on medication administration process (MAP)redesign and its achievements and challenges.

    Ferguson, Thomas A.; Church, Sara E.


    The first new design of United States currency in over 60 years will soon be issued. Its issuance will be the culmination of a 6-year effort to make U.S. currency more secure against widely available advanced reprographic technology. The cooperative effort was directed by the Advanced Counterfeit Deterrence (ACD) Steering Committee, with executive representatives from the Federal Reserve System (FRS), U.S. Secret Service (USSS), Bureau of Engraving and Printing (BEP) and Treasury Department. A task force of technical experts from each agency carried out the necessary evaluations. The overall strategy to determine the new design and new features applied a comprehensive, synergistic approach to target each type of currency user and each type of counterfeiting. To maximize objectivity yet expedite final selection, deterrent and detection technologies were evaluated through several parallel channels. These efforts included an open request for feature samples through the Commerce Business Daily, in-house testing of each feature, independent evaluation by the National Research Council, in-house design development and survey of world currencies. Recommendations were submitted by the Steering Committee to the Treasury Secretary for concept approval, announced in July 1994. Beginning in 1996, new designs will be issued by denomination approximately one per year, starting with the $100 bill. Future new design efforts will include input from the recently founded Securities Technology Institute (STI) at Johns Hopkins Applied Physics Laboratory. Input will include evaluation of existing features, development of new techniques and adversarial analysis.

    Soria, M C; Soria, M A; Bueno, D J; Godano, E I; Gómez, S C; ViaButron, I A; Padin, V M; Rogé, A D


    The performance of detection methods (culture methods and polymerase chain reaction assay) and plating media used in the same type of samples were determined as well as the specificity of PCR primers to detected Salmonella spp. contamination in layer hen farms. Also, the association of farm characteristics with Salmonella presence was evaluated. Environmental samples (feces, feed, drinking water, air, boot-swabs) and eggs were taken from 40 layer hen houses. Salmonella spp. was most detected in boot-swabs taken around the houses (30% and 35% by isolation and PCR, respectively) follow by fecal samples (15.2% and 13.6% by isolation and PCR, respectively). Eggs, drinking water, and air samples were negative for Salmonella detection. Salmonella Schwarzengrund and S. Enteritidis were the most isolated serotypes. For plating media, relative specificity was 1, and the relative sensitivity was greater for EF-18 agar than XLDT agar in feed and fecal samples. However, relative sensitivity was greater in XLDT agar than EF-18 agar for boot-swab samples. Agreement was between fair to good depending on the sample, and it was good between isolation and PCR (feces and boot-swabs), without agreement for feed samples. Salmonella spp. PCR was positive for all strains, while S. Typhimurium PCR was negative. Salmonella Enteritidis PCR used was not specific. Based in the multiple logistic regression analyses, categorization by counties was significant for Salmonella spp. presence (P-value = 0.010). This study shows the importance of considering different types of samples, plating media and detection methods during a Salmonella spp. monitoring study. In addition, it is important to incorporate the sampling of floors around the layer hen houses to learn if biosecurity measures should be strengthened to minimize the entry and spread of Salmonella in the houses. Also, the performance of some PCR methods and S. Enteritidis PCR should be improved, and biosecurity measures in hen farms must be

  14. Children's food preferences: effects of weight status, food type, branding and television food advertisements (commercials).

    Halford, Jason C G; Boyland, Emma J; Cooper, Gillian D; Dovey, Terence M; Smith, Cerise J; Williams, Nicola; Lawton, Clare L; Blundell, John E


    OBJECTIVE. To investigate the effects of weight status, food type and exposure to food and non-food advertisements on children's preference for branded and non-branded foods. DESIGN. A within-subjects, counterbalanced design with control (toy advertisement) and experimental (food advertisement) conditions. Subjects. A total of 37 school students (age: 11-13 years; weight status: 24 lean, 10 overweight, 3 obese). Measurements. Advertisement recall list, two food preference measures; the Leeds Food Preference Measure (LFPM), the Adapted Food Preference Measure (AFPM) and a food choice measure; the Leeds Forced-choice Test (LFCT). RESULTS. Normal weight children selected more branded and non-branded food items after exposure to food advertisements than in the control (toy advertisement) condition. Obese and overweight children showed a greater preference for branded foods than normal weight children per se, and also in this group only, there was a significant correlation between food advertisement recall and the total number of food items chosen in the experimental (food advertisement) condition. CONCLUSION. Exposure to food advertisements increased the preference for branded food items in the normal weight children. This suggests that television food advertisement exposure can produce the same 'obesigenic' food preference response found in overweight and obese children in their normal weight counterparts.

  15. Redesigned β γ radioxenon detector

    Cooper, Matthew W.; McIntyre, Justin I.; Bowyer, Ted W.; Carman, April J.; Hayes, James C.; Heimbigner, Tom R.; Hubbard, Charles W.; Lidey, Lance; Litke, Kevin E.; Morris, Scott J.; Ripplinger, Michael D.; Suarez, Reynold; Thompson, Robert


    The Automated Radio-xenon Sampler/Analyzer (ARSA), designed by Pacific Northwest National Laboratory (PNNL) collects and detects several radioxenon isotopes, and is used to monitor underground nuclear explosions. The ARSA is very sensitive to 133Xe, 131mXe, 133mXe, and 135Xe (SCM) [M. Auera et al., Wernspergera, Appl. Radiat. 6 (2004) 60] through use of its compact high efficiency β-γ coincidence detector. For this reason, it is an excellent treaty monitoring system and it can be used as an environmental sampling device as well. Field testing of the ARSA has shown it to be both robust and reliable, but the nuclear detector requires a detailed photomultiplier tube (PMT) gain matching regime difficult to implement in a field environment. Complexity is a problem from a maintenance and quality assurance/quality control (QA/QC) standpoint, and efforts to reduce these issues have led to development of a simplified β-γ coincident detector. The new design reduces the number of PMT's and the complexity of the calibration needed in comparison to the old design. New scintillation materials (NaI(Tl), CsI(Na), and CsI(Tl)) were investigated and a comparison of three different gamma sensitive well detectors has been completed. A new plastic-scintillator gas cell was constructed and a new method of forming the scintillator gas cell was developed. The simplified detector system compares favorably with the original ARSA design in spectral resolution and efficiency and is significantly easier to set up and calibrate. The new materials and configuration allow the resulting β-γ coincidence detector to maintain the overall performance of the ARSA type β-γ detector while simplifying the design.

  16. Development of redesign method of production system based on QFD

    Kondoh, Shinsuke; Umeda, Yasusi; Togawa, Hisashi

    In order to catch up with rapidly changing market environment, rapid and flexible redesign of production system is quite important. For effective and rapid redesign of production system, a redesign support system is eagerly needed. To this end, this paper proposes a redesign method of production system based on Quality Function Deployment (QFD). This method represents a designer's intention in the form of QFD, collects experts' knowledge as “Production Method (PM) modules,” and formulates redesign guidelines as seven redesign operations so as to support a designer to find out improvement ideas in a systematical manner. This paper also illustrates a redesign support tool of a production system we have developed based on this method, and demonstrates its feasibility with a practical example of a production system of a contact probe. A result from this example shows that comparable cost reduction to those of veteran designers can be achieved by a novice designer. From this result, we conclude our redesign method is effective and feasible for supporting redesign of a production system.

  17. Finance leadership imperatives in clinical redesign.

    Harris, John; Holm, Craig E; Inniger, Meredith C


    As physicians embrace their roles in managing healthcare costs and quality, finance leaders should seize the opportunity to engage physicians in clinical care redesign to ensure both high-quality performance and efficient resource use. Finance leaders should strike a balance between risk and reward to achieve a portfolio of clinical initiatives that is organizationally sustainable and responsive to current external drivers of payment changes. Because these initiatives should be driven by physicians, the new skill set of finance leaders should include an emphasis on relationship building to achieve consensus and drive change across an organization.

  18. Redesigning Health Information Systems in Developing Countries

    Mengiste, Shegaw Anagaw; Kimaro, Honest; Aanestad, Margunn


    Despite widespread aims to strengthen the Health Information System (HIS) as a tool for decentralised health care, there is a strong tendency in most developing countries that the HIS continues to reflect the central level's needs and requirements. The traditional design approach with little...... or no end user involvement results in a centralised HIS with an extensive, somewhat inappropriate, but also inflexible set of standards. Consequently, the HIS is not very useful for the wished-for decentralisation of health services, and there is an urgent need to redesign the existing HIS in order to make...

    Full Text Available Karen Jackson,1 Deborah E White,2 Jeanne Besner,1 Jill M Norris21Health Systems and Workforce Research Unit, Alberta Health Services, Calgary, Alberta, Canada; 2Faculty of Nursing, University of Calgary, Calgary, Alberta, CanadaBackground: Effective and efficient use of nursing human resources is critical. The Nursing Role Effectiveness Model conceptualizes nursing practice in terms of key clinical role accountabilities and has the potential to inform redesign efforts. The aims of this study were to develop, implement, and evaluate a job redesign intended to optimize the enactment of registered nurse (RN clinical role accountabilities.Methods: A job redesign was developed and implemented in a single medical patient care unit, the redesign unit. A mixed-methods design was used to evaluate the job redesign; a second medical patient care unit served as a control unit. Data from administrative databases, observations, interviews, and demographic surveys were collected pre-redesign (November 2005 and post-redesign (October 2007.Results: Several existing unit structures and processes (eg, model of care delivery influenced RNs' ability to optimally enact their role accountabilities. Redesign efforts were hampered by contextual issues, including organizational alignment, leadership, and timing. Overall, optimized enactment of RN role accountabilities and improvements to patient outcomes did not occur, yet this was predictable, given that the redesign was not successful. Although the results were disappointing, much was learned about job redesign.Conclusion: Potential exists to improve the utilization of nursing providers by situating nurses' work in a clinical role accountability framework and attending to a clear organizational vision and well-articulated strategic plan that is championed by leaders at all levels of the organization. Health care leaders require a clear understanding of nurses' role accountabilities, support in managing change, and

    Long Jun; Tian Huiping; Liu Yujian; Xie Chaogang; Li Jibing


    Over the past decades SINOPEC has been uninterruptedly engaging in the development and upgrading of deep catalytic cracking(DCC)technology for manufacturing propylene from heavy oil.Recently SINOPEC after having made a lot of progress in the area of oil refining at the molecular level has developed a new generation DMMC-1 type catalyst designed for the DCC process.The laboratory evaluation tests have shown that compared to the existing MMC-2 type catalyst that features the best comprehensive performance,the DMMC-1 type catalyst has increased the propylene yield by 2.2% with the propylene selectivity increased by 10%.The saidcatalyst has improved its ability for heavy oil cracking and coke selectivity along with reduction of olefin content in gasoline to achieve a better product distribution and improve the product quality.The resuIts of application of the said catalyst in a 650-kt/a commercial DCC unit at SINOPEC Anqing Branch Company have revealed that the DMMC-1 catalyst demonstrated an enhanced capabilitv for heavy oil cracking and could increase the total liquid yield to 84.56 m%from 83.92 m%,the LPG vield to 38.90 m% from 34.60 m%,the propylene yield to 17.80 m% from 15.37 m% and the propylene concentration to 45.91 m% from 44.91 m%,and reduce the coke yield from 7.61 m% to 7.05 m% and the olefin content in gasoline from 42.3v% to 37.5 v%,resulting in an incremental profit amounting to 52.19 million RMB a year.This technology has further upgradedand developed the DCC technology which has been commanding a leading position among the industry peers.


    Harish V. Katore,


    Full Text Available In Central India, various small scale industries are adopting the crude methodologies for designing & manufacturing the machine components. One such industry producing tractor trolleys for agricultural use has been identified for this study. The existing trolley designed by the industry uses heavy axle without consideringstatic and dynamic loading conditions which in turn leads to higher factor of safety increasing the overall cost of the axle. In this study, existing trolley axle is redesigned considering the static and dynamic load conditions. A CAD model is prepared using CATIA V5 as a tool. Minimum cross section for the axle is calculated which resulted in the 24.8 % reduction in the weight of the axle. The axle dimensions are redesigned to 75 X 75 mm which is comparatively smaller than the old axle. The design is optimized based on the manufacturing cost of the axle. The failure analysis is performed on the axle of trolley used in agricultural area. These results provide atechnical basis to prevent future damage to the location axle.

  11. Lessons from England's health care workforce redesign: no quick fixes.

    Bohmer, Richard M J; Imison, Candace


    In 2000 the English National Health Service (NHS) began a series of workforce redesign initiatives that increased the number of doctors and nurses serving patients, expanded existing staff roles and developed new ones, redistributed health care work, and invested in teamwork. The English workforce redesign experience offers important lessons for US policy makers. Redesigning the health care workforce is not a quick fix to control costs or improve the quality of care. A poorly planned redesign can even result in increased costs and decreased quality. Changes in skill mix and role definitions should be preceded by a detailed analysis and redesign of the work performed by health care professionals. New roles and responsibilities must be clearly defined in advance, and teamwork models that include factors common in successful redesigns such as leadership, shared objectives, and training should be promoted. The focus should be on retraining current staff instead of hiring new workers. Finally, any workforce redesign must overcome opposition from professional bodies, individual practitioners, and regulators. England's experience suggests that progress is possible if workforce redesigns are planned carefully and implemented with skill.

  13. Potential use of avocado oil on structured lipids MLM-type production catalysed by commercial immobilised lipases.

    Caballero, Eduardo; Soto, Carmen; Olivares, Araceli; Altamirano, Claudia


    Structured Lipids are generally constituents of functional foods. Growing demands for SL are based on a fuller understanding of nutritional requirements, lipid metabolism, and improved methods to produce them. Specifically, this work was aimed to add value to avocado oil by producing dietary triacylglycerols (TAG) containing medium-chain fatty acids (M) at positions sn-1,3 and long-chain fatty acids (L) at position sn-2. These MLM-type structured lipids (SL) were produced by interesterification of caprylic acid (CA) (C8:0) and avocado oil (content of C18:1). The regiospecific sn-1,3 commercial lipases Lipozyme RM IM and TL IM were used as biocatalysts to probe the potential of avocado oil to produce SL. Reactions were performed at 30-50°C for 24 h in solvent-free media with a substrate molar ratio of 1∶2 (TAG:CA) and 4-10% w/w enzyme content. The lowest incorporation of CA (1.1% mol) resulted from Lipozyme RM IM that was incubated at 50°C. The maximum incorporation of CA into sn-1,3 positions of TAG was 29.2% mol. This result was obtained at 30°C with 10% w/w Lipozyme TL IM, which is the highest values obtained in solvent-free medium until now for structured lipids of low-calories. This strategy opens a new market to added value products based on avocado oil.

  15. Redesigning photodetector electrodes as an optical antenna.

    Fan, Pengyu; Huang, Kevin C Y; Cao, Linyou; Brongersma, Mark L


    At the nanoscale, semiconductor and metallic structures naturally exhibit strong, tunable optical resonances that can be utilized to enhance light-matter interaction and to dramatically increase the performance of chipscale photonic elements. Here, we demonstrate that the metallic leads used to extract current from a Ge nanowire (NW) photodetector can be redesigned to serve as optical antennas capable of concentrating light in the NW. The NW itself can also be made optically resonant and an overall performance optimization involves a careful tuning of both resonances. We show that such a procedure can result in broadband absorption enhancements of up to a factor 1.7 at a target wavelength of 660 nm and an ability to control the detector's polarization-dependent response. The results of this study demonstrate the critical importance of performing a joint optimization of the electrical and optical properties of the metallic and semiconductor building blocks in optoelectronic devices with nanoscale components.

    Nicholas, John


    Lean production methods for eliminating waste and improving processes in manufacturing are now being applied in healthcare. As the author shows, the methods are appropriate for redesigning hospital facilities. When used in an integrated manner and employing teams of mostly clinicians, the methods produce facility designs that are custom-fit to patient needs and caregiver work processes, and reduce operational costs. The author reviews lean methods and an approach for integrating them in the redesign of hospital facilities. A case example of the redesign of an emergency department shows the feasibility and benefits of the approach.

    This study was conducted to compare carcass characteristics and physico-chemical meat quality in two different genotype ducks raised under identical feeding and rearing conditions. A total of ninety 1-d-old Korean native ducks (KND, n = 45) and commercial meat-type ducks (Grimaud, n = 45) were fed same experimental diets during 56 d and 42 d, respectively to obtain similar slaughter weights. The experimental diet for starter period contained 20% crude protein (CP) and 2,900 kcal nitrogen corrected true metabolizable energy (TMEn)/kg of diet and that for grower period contained 17% CP and 3,050 TMEn/kg of diet. Average daily gain and feed efficiency of KND were inferior to those of commercial meat-type ducks (pducks, but carcass yield of KND was significantly higher (pducks. There were no significant differences in cooking loss and pH of breast meat between two genetically different ducks, but water holding capacity of KND was significantly higher than that of commercial meat-type ducks. The linoleic acid and total polyunsaturated fatty acid of breast meat from KND were significantly higher (pducks. Significant differences were detected in water holding capacity and the content of linoleic acid and polyunsaturated fatty acid, which were significantly higher in KND, whereas growth performance tended to be superior in commercial ducks. At the market weight, the meat from KND was judged to have better qualities with regard to higher water holding capacity and greater content of polyunsaturated fatty acid compare with meat from commercial meat-type duck.

  2. Redesign of the DFT/MRCI Hamiltonian.

    Lyskov, Igor; Kleinschmidt, Martin; Marian, Christel M


    The combined density functional theory and multireference configuration interaction (DFT/MRCI) method of Grimme and Waletzke [J. Chem. Phys. 111, 5645 (1999)] is a well-established semi-empirical quantum chemical method for efficiently computing excited-state properties of organic molecules. As it turns out, the method fails to treat bi-chromophores owing to the strong dependence of the parameters on the excitation class. In this work, we present an alternative form of correcting the matrix elements of a MRCI Hamiltonian which is built from a Kohn-Sham set of orbitals. It is based on the idea of constructing individual energy shifts for each of the state functions of a configuration. The new parameterization is spin-invariant and incorporates less empirism compared to the original formulation. By utilizing damping techniques together with an algorithm of selecting important configurations for treating static electron correlation, the high computational efficiency has been preserved. The robustness of the original and redesigned Hamiltonians has been tested on experimentally known vertical excitation energies of organic molecules yielding similar statistics for the two parameterizations. Besides that, our new formulation is free from artificially low-lying doubly excited states, producing qualitatively correct and consistent results for excimers. The way of modifying matrix elements of the MRCI Hamiltonian presented here shall be considered as default choice when investigating photophysical processes of bi-chromophoric systems such as singlet fission or triplet-triplet upconversion.

The Bulletin will be available from the following distribution points: On the Meyrin...

  4. B-Target Room Tunnel Redesigned

    Esfandiari, Reza; /San Jose State U. /SLAC


    Several groups at SLAC National Accelerator Laboratory are currently working on a RF Modulator prototype for a future linear collider known as the International Linear Collider (ILC). The ILC runs using about a 1000 Klystrons which create high power carrier waves for the particle acceleration. Klystrons receive their electrical input power from modulators. In order to move beyond the prototype phase, the laboratory might expand its ground base further down a tunnel located at the End Station B (ESB) in order to house four new Klystron Modulator Test Stations. This area is known as the B-Target Room Tunnel, and the task was to redesign the tunnel layout for the upcoming changes. The project first began by collecting substantial amount of information about the prototyped project, the tunnel and the researchers feedback of what they would like to see in the upcoming design. Subsequent to numerous planning and presentations, one particular design was. Calculations for this design were then performed for the most complex aspects of the project. Based on the results of the calculations, specific sample beams, welds, bolts and materials were chosen for the possible future construction.

  5. A Redesign Approach for Improving Animal Care Services for Researchers.

    Okpe, Orighomisan; Kovach, Jamison V


    Because a research institution's animal care and use program oversees the provision of services specified in approved protocols designed by researchers, the effective provision of services within these programs is paramount to ensuring the humane care and treatment of research animals in accordance with federal, state, and local regulations and institutional policies. To improve the services provided to researchers through animal care and use programs, we investigated the relationship between the researchers who conduct these types of studies and the veterinary operations that provide care and treatment for research animals. Through a case study conducted at a leading public research university, we used an action-research approach to redesign aspects of the process through which researchers and the veterinary operations interact by using the Design for Six Sigma methodology. Using this structured approach for building quality into the design of a process to better serve customers, we identified and prioritized researchers' expectations regarding the role of veterinary operations in supporting their animal research activities. In addition, ideas for addressing researchers' top-rated needs were generated through focus groups. By updating online resources, creating checklists and newsletters, and hiring additional veterinary staff, the services provided were amended to provide researchers with increased access to valuable information, improved clarity regarding the process for obtaining access to research facilities, and enhanced support for animal care services.

  6. Job crafting: Towards a new model of individual job redesign

    Maria Tims


    Full Text Available Orientation: For a long time, employees have been viewed as passive performers of their assigned job tasks. Recently, several scholars have argued that job design theory needs to address the influence of employees on their job designs.Research purpose: The purpose of the study was to fit job crafting in job design theory.Motivation for the study: The study was an attempt to shed more light on the types of proactive behaviours of individual employees at work. Moreover, we explored the concept of job crafting and its antecedents and consequences.Research design, approach and method: A literature study was conducted in which the focus was first on proactive behaviour of the employee and then on job crafting.Main findings: Job crafting can be seen as a specific form of proactive behaviour in which the employee initiates changes in the level of job demands and job resources. Job crafting may be facilitated by job and individual characteristics and may enable employees to fit their jobs to their personal knowledge, skills and abilities on the one hand and to their preferences and needs on the other hand.Practical/managerial implications: Job crafting may be a good way for employees to improve their work motivation and other positive work outcomes. Employees could be encouraged to exert more influence on their job characteristics.Contribution/value-add: This article describes a relatively new perspective on active job redesign by the individual, called job crafting, which has important implications for job design theories.

  7. Pre-Eminance of Open Source Eda Tools and Its Types in The Arena of Commercial Electronics

    Geeta Yadav


    Full Text Available Digital synthesis with a goal of chip designing in the commercial electronics arena is packed into large EDA Software providers like, Synopsys, Cadence, or MentorGraphics. These commercial tools being expensive and having closed file structures. It is also a financial constraint for the startup companies sometimes who have their budget limitations. Any bug-fixes or add features cannot be made with ease; in such scenario the company is forced to opt for an alternative cost effective EDA software. This paper deals with the advantages of using open source EDA tools like Icarus Verilog, Verilator, GTKwave viewer, GHDL VHDL simulator, gEDA, etc. that are available as a free source and focuses on the Icarus Verilog simulator tool. It can be seen as a big encouragement for startups in Semiconductor domain. Thereby, these open source EDA tools make the design process more cost-effective, less time consuming and affordable as well.

  8. Robust control of uncertain nonlinear switched genetic regulatory networks with time delays: A redesign approach.

    Moradi, Hojjatullah; Majd, Vahid Johari


    In this paper, the problem of robust stability of nonlinear genetic regulatory networks (GRNs) is investigated. The developed method is an integral sliding mode control based redesign for a class of perturbed dissipative switched GRNs with time delays. The control law is redesigned by modifying the dissipativity-based control law that was designed for the unperturbed GRNs with time delays. The switched GRNs are switched from one mode to another based on time, state, etc. Although, the active subsystem is known in any instance, but the switching law and the transition probabilities are not known. The model for each mode is considered affine with matched and unmatched perturbations. The redesigned control law forces the GRN to always remain on the sliding surface and the dissipativity is maintained from the initial time in the presence of the norm-bounded perturbations. The global stability of the perturbed GRNs is maintained if the unperturbed model is globally dissipative. The designed control law for the perturbed GRNs guarantees robust exponential or asymptotic stability of the closed-loop network depending on the type of stability of the unperturbed model. The results are applied to a nonlinear switched GRN, and its convergence to the origin is verified by simulation.

  10. Developing an evaluation framework for clinical redesign programs: lessons learnt.

    Samaranayake, Premaratne; Dadich, Ann; Fitzgerald, Anneke; Zeitz, Kathryn


    Purpose The purpose of this paper is to present lessons learnt through the development of an evaluation framework for a clinical redesign programme - the aim of which was to improve the patient journey through improved discharge practices within an Australian public hospital. Design/methodology/approach The development of the evaluation framework involved three stages - namely, the analysis of secondary data relating to the discharge planning pathway; the analysis of primary data including field-notes and interview transcripts on hospital processes; and the triangulation of these data sets to devise the framework. The evaluation framework ensured that resource use, process management, patient satisfaction, and staff well-being and productivity were each connected with measures, targets, and the aim of clinical redesign programme. Findings The application of business process management and a balanced scorecard enabled a different way of framing the evaluation, ensuring measurable outcomes were connected to inputs and outputs. Lessons learnt include: first, the importance of mixed-methods research to devise the framework and evaluate the redesigned processes; second, the need for appropriate tools and resources to adequately capture change across the different domains of the redesign programme; and third, the value of developing and applying an evaluative framework progressively. Research limitations/implications The evaluation framework is limited by its retrospective application to a clinical process redesign programme. Originality/value This research supports benchmarking with national and international practices in relation to best practice healthcare redesign processes. Additionally, it provides a theoretical contribution on evaluating health services improvement and redesign initiatives.

  12. The Role of the IT Department in Organizational Redesign.

    Petersen, Lone Stub


    Focus within eHealth research is often on development and implementation. However, the role of information systems maintenance and management is often neglected. In order for the IT department to accommodate the needs of the hospitals and continuous change of organization and practice there is a need for developing an understanding of the complex relationship between the IT department and clinical practice. In this paper the concept of redesign is used to deepen our understanding of IT related organizational change in healthcare organizations. In the paper I argue that the IT department is a central partner, steward and power in organizational change and learning in hospitals as the IT department serve both as a barrier and a catalyst of change and flexibility in the organization through management of information systems maintenance and redesign. Therefore it is important to consider and secure appropriate forms for stewarding redesign and learning in cooperation between the health care organizations and the IT department.


    Alic BIRCA


    Full Text Available This paper addresses the design and redesign of jobs under psychological aspect. For many years, the design and redesign of jobs have been treated more economically, i.e. by reducing staff costs. Although in the short-term, this approach has had positive economic effects, in the long-term the economic effects have been negative. Starting from this point of view, the authors attempt to highlight the problems that the psychological aspects involve in the design and redesign of jobs. Given the psychological aspects in the design of jobs aspects, are taken into consideration, certain problems that can have a far greater impact on organizational performance, may be anticipated and excluded.

  14. Application of Computer Simulation Modeling to Medication Administration Process Redesign

    Nathan Huynh


    Full Text Available The medication administration process (MAP is one of the most high-risk processes in health care. MAP workflow redesign can precipitate both unanticipated and unintended consequences that can lead to new medication safety risks and workflow inefficiencies. Thus, it is necessary to have a tool to evaluate the impact of redesign approaches in advance of their clinical implementation. This paper discusses the development of an agent-based MAP computer simulation model that can be used to assess the impact of MAP workflow redesign on MAP performance. The agent-based approach is adopted in order to capture Registered Nurse medication administration performance. The process of designing, developing, validating, and testing such a model is explained. Work is underway to collect MAP data in a hospital setting to provide more complex MAP observations to extend development of the model to better represent the complexity of MAP.


    PEJIĆ Petar


    Full Text Available Augmented Reality (AR is a computer technology where the perception of the user is enhanced by the seamless blending between real environment and computer-generated virtual objects coexisting in the same space. When it comes to a redesign of the existing facades, it is necessary to create a visual presentation of the proposed changes. For this reason, contemporary architectural approach assumes creating a digital 3D model of the newly designed facade. Since the façade redesign is a real world change, the AR can be used for newly designed facade project presentation. In this paper a case study of the AR application for façade redesign presentation of a single family house located in Babušnica (Serbia is presented.

  16. Process redesign for time-based emergency admission targets.

    G Leggat, Sandra; Gough, Richard; Bartram, Timothy; Stanton, Pauline; Bamber, Greg J; Ballardie, Ruth; Sohal, Amrik


    Purpose Hospitals have used process redesign to increase the efficiency of the emergency department (ED) to cope with increasing demand. While there are published studies suggesting a positive outcome, recent reviews have reported that it is difficult to conclude that these approaches are effective as a result of substandard research methodology. The purpose of this paper is to explore the perceptions of hospital staff on the impact of a process redesign initiative on quality of care. Design/methodology/approach A retrospective qualitative case study examining a Lean Six Sigma (LSS) initiative in a large metropolitan hospital from 2009 to 2010. Non-probability sampling identified interview subjects who, through their participation in the redesign initiative, had a detailed understanding of the implementation and outcomes of the initiative. Between April 2012 and January 2013 26 in-depth semi-structured interviews were conducted and analysed with thematic content analysis. Findings There were four important findings. First, when asked to comment on the impact of the LSS implementation, without prompting the staff spoke of quality of care. Second, there was little agreement among the participants as to whether the project had been successful. Third, despite the recognition of the need for a coordinated effort across the hospital to improve ED access, the redesign process was not successful in reducing existing divides among clinicians and among managers and clinicians. Finally, staff expressed tension between production processes to move patients more quickly and their duty of care to their patients as individuals. Originality/value One of the first studies to explore the impact of process redesign through in-depth interviews with participating staff, this study adds further evidence that organisations implementing process redesign must ensure the supporting management practices are in place.

  17. Lessons in redesigning a quality program across the continuum.

    Brown, Diane Storer; Church, Lauri; Heywood, Terry; Hills, John F; McCarthy, Sarah; Serway, Cindy


    The Kaiser Permanente North East Bay service area redesigned its quality program beginning in 1995, to better mirror how care was provided across the continuum. The old model had evolved over time, was based on departmental structure, and did not focus on all patient populations. The purpose of this article is to describe the redesign process, the quality model implemented, and future directions, with the hope that the lessons learned will provide other healthcare quality professionals some of the knowledge needed and, perhaps, the courage to "design" their quality programs.

  18. Spacecraft redesign to reduce microphonic response of a VCO component

    Strain, J. C.; Mittal, S.


    Reaction wheel vibration was found to induce out of specification sidebands on the carrier frequencies of some spacecraft components containing mechanical voltage control oscillators (VCOs). Concurrent investigations were performed to redesign the VCOs to reduce their response to the wheel vibration, and to design a reaction wheel isolation system to reduce the vibration input to the affected components. Component level tests indicated that both efforts provided viable solutions. The redesigned VCO will be incorporated into future spacecraft in the series, while affected spacecraft already in production will be retrofitted with the reaction wheel isolation system.

  4. Multi-stakeholder collaboration in the redesign of family-centered rounds process.

    Xie, Anping; Carayon, Pascale; Cartmill, Randi; Li, Yaqiong; Cox, Elizabeth D; Plotkin, Julie A; Kelly, Michelle M


    A human factors approach to healthcare system redesign emphasizes the involvement of multiple healthcare stakeholders (e.g., patients and families, healthcare providers) in the redesign process. This study explores the experience of multiple stakeholders with collaboration in a healthcare system redesign project. Interviews were conducted with ten stakeholder representatives who participated in the redesign of the family-centered rounds process in a pediatric hospital. Qualitative interview data were analyzed using a phenomenological approach. A model of collaborative healthcare system redesign was developed, which defined four phases (i.e., setup of the redesign team, preparation for meetings, collaboration in meetings, follow-up after meetings) and two outcomes (i.e., team outcomes, redesign outcomes) of the collaborative process. Challenges to multi-stakeholder collaboration in healthcare system redesign, such as need to represent all relevant stakeholders, scheduling of meetings and managing different perspectives, were identified.

  5. Commercial-Scale Performance Predictions for High-Temperature Electrolysis Plants Coupled to Three Advanced Reactor Types

    M. G. McKellar; J. E. O' Brien; J. S. Herring


    This report presents results of system analyses that have been developed to assess the hydrogen production performance of commercial-scale high-temperature electrolysis (HTE) plants driven by three different advanced reactor – power-cycle combinations: a high-temperature helium cooled reactor coupled to a direct Brayton power cycle, a supercritical CO2-cooled reactor coupled to a direct recompression cycle, and a sodium-cooled fast reactor coupled to a Rankine cycle. The system analyses were performed using UniSim software. The work described in this report represents a refinement of previous analyses in that the process flow diagrams include realistic representations of the three advanced reactors directly coupled to the power cycles and integrated with the high-temperature electrolysis process loops. In addition, this report includes parametric studies in which the performance of each HTE concept is determined over a wide range of operating conditions. Results of the study indicate that overall thermal-to- hydrogen production efficiencies (based on the low heating value of the produced hydrogen) in the 45 - 50% range can be achieved at reasonable production rates with the high-temperature helium cooled reactor concept, 42 - 44% with the supercritical CO2-cooled reactor and about 33 - 34% with the sodium-cooled reactor.

  2. A Lightweight Structure Redesign Method Based on Selective Laser Melting

    Li Tang


    Full Text Available The purpose of this paper is to present a new design method of lightweight parts fabricated by selective laser melting (SLM based on the “Skin-Frame” and to explore the influence of fabrication defects on SLM parts with different sizes. Some standard lattice parts were designed according to the Chinese GB/T 1452-2005 standard and manufactured by SLM. Then these samples were tested in an MTS Insight 30 compression testing machine to study the trends of the yield process with different structure sizes. A set of standard cylinder samples were also designed according to the Chinese GB/T 228-2010 standard. These samples, which were made of iron-nickel alloy (IN718, were also processed by SLM, and then tested in the universal material testing machine INSTRON 1346 to obtain their tensile strength. Furthermore, a lightweight redesigned method was researched. Then some common parts such as a stopper and connecting plate were redesigned using this method. These redesigned parts were fabricated and some application tests have already been performed. The compression testing results show that when the minimum structure size is larger than 1.5 mm, the mechanical characteristics will hardly be affected by process defects. The cylinder parts were fractured by the universal material testing machine at about 1069.6 MPa. These redesigned parts worked well in application tests, with both the weight and fabrication time of these parts reduced more than 20%.

  4. Effect of genetic and phenotypic factors on the composition of commercial marmande type tomatoes studied through HRMAS NMR spectroscopy.

    Iglesias, María José; García López, Jesús; Collados Luján, Juan Fernando; López Ortiz, Fernando; Bojórquez Pereznieto, Humberto; Toresano, Fernando; Camacho, Francisco


    The effects of genetic, technological and environmental factors on the chemical composition of four marmande type tomato varieties have been investigated. The study is based on the analysis of (1)H HRMAS NMR spectra of tomato purée using a combination of partial least squares (PLS) and assigned signal analysis (ASA). In agreement with genetic, morphological and taste characteristics of the tomatoes studied, the analysis of the NMR data allows two groups of samples to be differentiated. The type of culture and climatic conditions can reduce the compositional differences. The extension of the compositional changes produced by climatic conditions is variety-depend. Neither grafting nor perlite affect significantly the relative content of primary metabolites. This was not the case for tomatoes grown using the pure hydroponic production system based on the recirculation of nutrient solution, New Growing System NGS®, which seems to be an effective agricultural approach to improve tomato quality.

  5. Near-field commercial aircraft contribution to nitrogen oxides by engine, aircraft type, and airline by individual plume sampling.

    Carslaw, David C; Ropkins, Karl; Laxen, Duncan; Moorcroft, Stephen; Marner, Ben; Williams, Martin L


    Nitrogen oxides (NOx) concentrations were measured in individual plumes from aircraft departing on the northern runway at Heathrow Airport in west London. Over a period of four weeks 5618 individual plumes were sampled by a chemiluminescence monitor located 180 m from the runway. Results were processed and matched with detailed aircraft movement and aircraft engine data using chromatographic techniques. Peak concentrations associated with 29 commonly used engines were calculated and found to have a good relationship with N0x emissions taken from the International Civil Aviation Organization (ICAO) databank. However, it is found that engines with higher reported NOx emissions result in proportionately lower NOx concentrations than engines with lower emissions. We show that it is likely that aircraft operational factors such as takeoff weight and aircraftthrust setting have a measurable and important effect on concentrations of N0x. For example, NOx concentrations can differ by up to 41% for aircraft using the same airframe and engine type, while those due to the same engine type in different airframes can differ by 28%. These differences are as great as, if not greater than, the reported differences in NOx emissions between different engine manufacturers for engines used on the same airframe.

  6. Entrance dose measurements for in-vivo diode dosimetry: Comparison of correction factors for two types of commercial silicon diode detectors.

    Zhu, X R


    Silicon diode dosimeters have been used routinely for in-vivo dosimetry. Despite their popularity, an appropriate implementation of an in-vivo dosimetry program using diode detectors remains a challenge for clinical physicists. One common approach is to relate the diode readout to the entrance dose, that is, dose to the reference depth of maximum dose such as d(max) for the 10x10 cm(2) field. Various correction factors are needed in order to properly infer the entrance dose from the diode readout, depending on field sizes, target-to-surface distances (TSD), and accessories (such as wedges and compensate filters). In some clinical practices, however, no correction factor is used. In this case, a diode-dosimeter-based in-vivo dosimetry program may not serve the purpose effectively; that is, to provide an overall check of the dosimetry procedure. In this paper, we provide a formula to relate the diode readout to the entrance dose. Correction factors for TSD, field size, and wedges used in this formula are also clearly defined. Two types of commercial diode detectors, ISORAD (n-type) and the newly available QED (p-type) (Sun Nuclear Corporation), are studied. We compared correction factors for TSDs, field sizes, and wedges. Our results are consistent with the theory of radiation damage of silicon diodes. Radiation damage has been shown to be more serious for n-type than for p-type detectors. In general, both types of diode dosimeters require correction factors depending on beam energy, TSD, field size, and wedge. The magnitudes of corrections for QED (p-type) diodes are smaller than ISORAD detectors.

  7. Vibration reduction of pneumatic percussive rivet tools: mechanical and ergonomic re-design approaches.

    Cherng, John G; Eksioglu, Mahmut; Kizilaslan, Kemal


    This paper presents a systematic design approach, which is the result of years of research effort, to ergonomic re-design of rivet tools, i.e. rivet hammers and bucking bars. The investigation was carried out using both ergonomic approach and mechanical analysis of the rivet tools dynamic behavior. The optimal mechanical design parameters of the re-designed rivet tools were determined by Taguchi method. Two ergonomically re-designed rivet tools with vibration damping/isolation mechanisms were tested against two conventional rivet tools in both laboratory and field tests. Vibration characteristics of both types of tools were measured by laboratory tests using a custom-made test fixture. The subjective field evaluations of the tools were performed by six experienced riveters at an aircraft repair shop. Results indicate that the isolation spring and polymer damper are very effective in reducing the overall level of vibration under both unweighted and weighted acceleration conditions. The mass of the dolly head and the housing played a significant role in the vibration absorption of the bucking bars. Another important result was that the duct iron has better vibration reducing capability compared to steel and aluminum for bucking bars. Mathematical simulation results were also consistent with the experimental results. Overall conclusion obtained from the study was that by applying the design principles of ergonomics and by adding vibration damping/isolation mechanisms to the rivet tools, the vibration level can significantly be reduced and the tools become safer and user friendly. The details of the experience learned, design modifications, test methods, mathematical models and the results are included in the paper.

We tested our final stacked picture with a picture obtained from two high-end focus stacking solutions: a Leica MZ16A with DFC500 and a Leica Z6APO with DFC290. Zerene Stacker and Helicon Focus both provided satisfactory results. However, Zerene Stacker gives the user more possibilities in terms of control of the software, batch processing and retouching. The outcome of the test on high-end solutions demonstrates that our approach performs better in several ways. The resolution of the tested extended focus pictures is much higher than those from the Leica systems. The flash lighting inside the Ikea closet creates an evenly illuminated picture, without struggling with filters, diffusers, etc. The largest benefit is the price of the set-up which is approximately € 3,000, which is 8 and 10 times less than the LeicaZ6APO and LeicaMZ16A set-up respectively. Overall, this enables institutions to purchase multiple solutions or to start digitising the type collection on a large scale even with a small budget.

    In this manuscript we present a focus stacking system, composed of commercial photographic equipment. The system is inexpensive compared to high-end commercial focus stacking solutions. We tested this system and compared the results with several different software packages (CombineZP, Auto-Montage, Helicon Focus and Zerene Stacker). We tested our final stacked picture with a picture obtained from two high-end focus stacking solutions: a Leica MZ16A with DFC500 and a Leica Z6APO with DFC290. Zerene Stacker and Helicon Focus both provided satisfactory results. However, Zerene Stacker gives the user more possibilities in terms of control of the software, batch processing and retouching.

    Zhai, Shao-Lun; Chen, Sheng-Nan; Liu, Wei; Li, Xiao-Peng; Deng, Su-Fang; Wen, Xiao-Hui; Luo, Man-Lin; Lv, Dian-Hong; Wei, Wen-Kang; Chen, Rui-Ai


    Porcine circovirus type 2 (PCV2) is considered the major etiological pathogen of porcine circovirus-associated diseases (PCVADs) in pigs. Recently, PCV2 was also found in non-porcine animals such as cattle, rats, and mice. However, there was no record of PCV2 in rats in China. The goal of this study was to investigate whether PCV2 was present in rats (Rattus norvegicus, RN) on three swine farms, using molecular tools. PCR results showed that 30 of 95 (31.6 %) rat samples were positive for PCV2. Moreover, further genotype analysis suggested that 10 of 30 (33.3 %) were positive for PCV2a, 19 of 30 (63.3 %) were positive for PCV2b, and only one sample (1/30, 3.33 %) was co-infected by PCV2a and PCV2b. To determine the possible origin of PCV2, 60 serum samples were also collected from weaned pigs on those swine farms, and 23 out of 60 samples were positive for PCV2. In addition, two distinct RN-origin and two distinct porcine-origin PCV2 full-length nucleotide sequences were obtained from the farms. Sequence and phylogenetic analysis indicated that they had the highest nucleotide similarity and closest genetic relationships to each other. In this study, we report the infection and genome characterization of PCV2 in rats and compare RN-origin and porcine-origin PCV2 sequences obtained from the same pig farm, revealing possible cross-species transmission of PCV2.

  12. Nurses' expectations and perceptions of a redesigned Electronic Health Record.

    Gonzalez, Zulma; Recondo, Francisco; Sommer, Janine; Schachner, Bibiana; Garcia, Gabriela; Luna, Daniel; Benítez, Sonia


    When a new Electronic Health Record is implemented or modifications are made, the full acceptance by end users depends on their expectations and perceptions about the possible benefits and the potential impacts on care quality. The redesign of an electronic nurse chart should consider the inherent characteristics of nurses' practice and the variables that may influence the implementation and use of the new chart. In this study, a qualitative method evaluated nurses' expectations and perceptions about the implementation impacts of a redesigned nurse chart in an electronic health record at Hospital Italiano de Buenos Aires. Seventy-four nurses participated in three operative groups. Following ground theory, three analytic dimensions were found: impact at work, communication and chart quality. In addition, time was a recurrent topic. Nurses found it difficult to think positively if reduction in time of documentation was not assured.

  13. Cost effectiveness of ergonomic redesign of electronic motherboard.

    Sen, Rabindra Nath; Yeow, Paul H P


    A case study to illustrate the cost effectiveness of ergonomic redesign of electronic motherboard was presented. The factory was running at a loss due to the high costs of rejects and poor quality and productivity. Subjective assessments and direct observations were made on the factory. Investigation revealed that due to motherboard design errors, the machine had difficulty in placing integrated circuits onto the pads, the operators had much difficulty in manual soldering certain components and much unproductive manual cleaning (MC) was required. Consequently, there were high rejects and occupational health and safety (OHS) problems, such as, boredom and work discomfort. Also, much labour and machine costs were spent on repairs. The motherboard was redesigned to correct the design errors, to allow more components to be machine soldered and to reduce MC. This eliminated rejects, reduced repairs, saved US dollars 581495/year and improved operators' OHS. The customer also saved US dollars 142105/year on loss of business.

  14. PEM Fuel Cells Redesign Using Biomimetic and TRIZ Design Methodologies

    Fung, Keith Kin Kei

    Two formal design methodologies, biomimetic design and the Theory of Inventive Problem Solving, TRIZ, were applied to the redesign of a Proton Exchange Membrane (PEM) fuel cell. Proof of concept prototyping was performed on two of the concepts for water management. The liquid water collection with strategically placed wicks concept demonstrated the potential benefits for a fuel cell. Conversely, the periodic flow direction reversal concepts might cause a potential reduction water removal from a fuel cell. The causes of this water removal reduction remain unclear. In additional, three of the concepts generated with biomimetic design were further studied and demonstrated to stimulate more creative ideas in the thermal and water management of fuel cells. The biomimetic design and the TRIZ methodologies were successfully applied to fuel cells and provided different perspectives to the redesign of fuel cells. The methodologies should continue to be used to improve fuel cells.

    Full Text Available This project is conducted in Company X, a passenger cars wheel producing company located in Sunter, North Jakarta. With a view of increasing the productivity of the company, the focus of this project will be redesigned the layout of the factory. The main problem encountered is that the goods are not produced in single location, causing a considerable hindrance in terms of time and distance, and hence efficiency. The redesigning layout process will use SLP method and flow analysis while supported by analysis of assembly line balancing to optimize the layout. Regarding the evaluation process, ARENA software will be used to simulate and identify the bottleneck in the production process, and comparing the layout alternatives to decide the best layout. The best chosen layout according to the simulation and SLP method that supported with flow analysis and assembly line balancing will be used as the master draft layout that will be proposed to Company X.

  17. Redesigning ambulatory care business processes supporting clinical care delivery.

    Patterson, C; Sinkewich, M; Short, J; Callas, E


    The first step in redesigning the health care delivery process for ambulatory care begins with the patient and the business processes that support the patient. Patient-related business processes include patient access, service documentation, billing, follow-up, collection, and payment. Access is the portal to the clinical delivery and care management process. Service documentation, charge capture, and payment and collection are supporting processes to care delivery. Realigned provider networks now demand realigned patient business services to provide their members/customers/patients with improved service delivery at less cost. Purchaser mandates for cost containment, health maintenance, and enhanced quality of care have created an environment where every aspect of the delivery system, especially ambulatory care, is being judged. Business processes supporting the outpatient are therefore being reexamined for better efficiency and customer satisfaction. Many health care systems have made major investments in their ambulatory care environment, but have pursued traditional supporting business practices--such as multiple access points, lack of integrated patient appointment scheduling and registration, and multiple patient bills. These are areas that are appropriate for redesign efforts--all with the customer's needs and convenience in mind. Similarly, setting unrealistic expectations, underestimating the effort required, and ignoring the human elements of a patient-focused business service redesign effort can sabotage the very sound reasons for executing such an endeavor. Pitfalls can be avoided if a structured methodology, coupled with a change management process, are employed. Deloitte & Touche Consulting Group has been involved in several major efforts, all with ambulatory care settings to assist with the redesign of their business practices to consider the patient as the driver, instead of the institution providing the care.

  19. Acceptance of lean redesigns in primary care: A contextual analysis.

    Hung, Dorothy; Gray, Caroline; Martinez, Meghan; Schmittdiel, Julie; Harrison, Michael I

    Lean is a leading change strategy used in health care to achieve short-term efficiency and quality improvement while promising longer-term system transformation. Most research examines Lean intervention to address isolated problems, rather than to achieve broader systemic changes to care delivery. Moreover, no studies examine contextual influences on system-wide Lean implementation efforts in primary care. The aim of this study was to identify contextual factors most critical to implementing and scaling Lean redesigns across all primary care clinics in a large, ambulatory care delivery system. Over 100 interviews and focus groups were conducted with frontline physicians, clinical staff, and operational leaders. Data analysis was guided by a modified Consolidated Framework for Implementation Research (CFIR), a popular implementation science framework. On the basis of expert recommendations, the modified framework targets factors influencing the implementation of process redesigns. This modified framework, the CFIR-PR, informed our identification of contextual factors that most impacted Lean acceptance among frontline physicians and staff. Several domains identified by the CFIR-PR were critical to acceptance of Lean redesigns. Regarding the implementation process acceptance was influenced by time and intensity of exposure to changes, "top-down" versus "bottom-up" implementation styles, and degrees of employee engagement in developing new workflows. Important factors in the inner setting were the clinic's culture and style of leadership, along with availability of information about Lean's effectiveness. Last, implementation efforts were impacted by individual and team characteristics regarding changed work roles and related issues of professional identity, authority, and autonomy. This study underscores the need for change leaders to consider the contextual factors that surround efforts to implement Lean in primary care. As Lean redesigns are scaled across a system

    The world's crop productivity is stagnating whereas population growth, rising affluence, and mandates for biofuels put increasing demands on agriculture. Meanwhile, demand for increasing cropland competes with equally crucial global sustainability and environmental protection needs. Addressing this looming agricultural crisis will be one of our greatest scientific challenges in the coming decades, and success will require substantial improvements at many levels. We assert that increasing the efficiency and productivity of photosynthesis in crop plants will be essential if this grand challenge is to be met. Here, we explore an array of prospective redesigns of plant systems at various scales, all aimed at increasing crop yields through improved photosynthetic efficiency and performance. Prospects range from straightforward alterations, already supported by preliminary evidence of feasibility, to substantial redesigns that are currently only conceptual, but that may be enabled by new developments in synthetic biology. Although some proposed redesigns are certain to face obstacles that will require alternate routes, the efforts should lead to new discoveries and technical advances with important impacts on the global problem of crop productivity and bioenergy production.

  2. Redesign of Transjakarta Bus Driver's Cabin

    Mardi Safitri, Dian; Azmi, Nora; Singh, Gurbinder; Astuti, Pudji


    Ergonomic risk at work stations with type Seated Work Control was one of the problems faced by Transjakarta bus driver. Currently “Trisakti” type bus, one type of bus that is used by Transjakarta in corridor 9, serving route Pinang Ranti - Pluit, gained many complaints from drivers. From the results of Nordic Body Map questionnaires given to 30 drivers, it was known that drivers feel pain in the neck, arms, hips, and buttocks. Allegedly this was due to the seat position and the button/panel bus has a considerable distance range (1 meter) to be achieved by drivers. In addition, preliminary results of the questionnaire using Workstation Checklist identified their complaints about uncomfortable cushion, driver's seat backrest, and the exact position of the AC is above the driver head. To reduce the risk level of ergonomics, then did research to design the cabin by using a generic approach to designing products. The risk analysis driver posture before the design was done by using Rapid Upper Limb Assessment (RULA), Rapid Entire Body Assessment (REBA), and Quick Exposure Checklist (QEC), while the calculation of the moment the body is done by using software Mannequin Pro V10.2. Furthermore, the design of generic products was done through the stages: need metric-matrix, house of quality, anthropometric data collection, classification tree concept, concept screening, scoring concept, design and manufacture of products in the form of two-dimensional. While the design after design risk analysis driver posture was done by using RULA, REBA, and calculation of moments body as well as the design visualized using software 3DMax. From the results of analysis before the draft design improvements cabin RULA obtained scores of 6, REBA 9, and the result amounted to 57.38% QEC and moment forces on the back is 247.3 LbF.inch and on the right hip is 72.9 While the results of the proposed improvements cabin design RULA obtained scores of 3, REBA 4, and the moment of force on

  3. A skim milk stabilized water vaccine for Newcastle disease (B1-type LaSota): its effectiveness under modern commercial cage layer methods of delivery.

    Woodward, H L; Tudor, D C


    For flock vaccination, B1-type LaSota Newcastle disease water vaccine was used in chicken under commercial cage layer conditions using two different methods, Swish Corporation pipes and cups, and stainless stell troughs, in an effort to determine their effectiveness. The concentration of virus in trough and cup samples collected at the beginning and the end of the lines were the same except in one instance where little or no virus was transported to the end of the trough. Satisfactory results were obtained when the test was repeated a year later. Serum HI titers determined before and after vaccination demonstrated adequate flock serum titers and indicated that both methods of application were reasonably effective. In laboratory trials, different water pipes (black, polyvinyl chloride pipe and Hart cups, green, polyvinyl chloride pipe and Swish cups, and old, rusty, galvanized pipe) normally used in cage operations were tested. Our findings indicated that dried skim milk powder (DSMP) was essential in stabilizing vaccine virus in the containers tested and that an adequate vaccine virus concentration was maintained in the three types of pipe tested when DSMP was used. Without DSMP the vaccine titers were adversely affected.

  4. Effect of soil type and soil management on soil physical, chemical and biological properties in commercial organic olive orchards in Southern Spain

    Gomez, Jose Alfonso; Auxiliadora Soriano, Maria; Montes-Borrego, Miguel; Navas, Juan Antonio; Landa, Blanca B.


    One of the objectives of organic agriculture is to maintain and improve soil quality, while simultaneously producing an adequate yield. A key element in organic olive production is soil management, which properly implemented can optimize the use of rainfall water enhancing infiltration rates and controlling competition for soil water by weeds. There are different soil management strategies: eg. weed mowing (M), green manure with surface tillage in spring (T), or combination with animal grazing among the trees (G). That variability in soil management combined with the large variability in soil types on which organic olive trees are grown in Southern Spain, difficult the evaluation of the impact of different soil management on soil properties, and yield as well as its interpretation in terms of improvement of soil quality. This communications presents the results and analysis of soil physical, chemical and biological properties on 58 soils in Southern Spain during 2005 and 2006, and analyzed and evaluated in different studies since them. Those 58 soils were sampled in 46 certified commercial organic olive orchards with four soil types as well as 12 undisturbed areas with natural vegetation near the olive orchards. The four soil types considered were Eutric Regosol (RGeu, n= 16), Eutric Cambisol (CMeu, n=16), Calcaric Regosol (RGca, n=13 soils sampled) and Calcic Cambisol (CMcc), and the soil management systems (SMS) include were 10 light tillage (LT), 16 sheep grazing (G), 10 tillage (T), 10 mechanical mowing (M), and 12 undisturbed areas covered by natural vegetation (NV-C and NV-S). Our results indicate that soil management had a significant effect on olive yield as well as on key soil properties. Among these soil properties are physical ones, such as infiltration rate or bulk density, chemical ones, especially organic carbon concentration, and biological ones such as soil microbial respiration and bacterial community composition. Superimpose to that soil

  5. Computational Insight to Improve the Thermal Isomerisation Performance of Overcrowded Alkene-Based Molecular Motors through Structural Redesign.

    Oruganti, Baswanth; Wang, Jun; Durbeej, Bo


    Synthetic overcrowded alkene-based molecular motors achieve 360° unidirectional rotary motion of one motor half (rotator) relative to the other (stator) through sequential photochemical and thermal isomerisation steps. In order to facilitate and expand the use of these motors for various applications, it is important to investigate ways to increase the rates and efficiencies of the reactions governing the rotary motion. Here, we use computational methods to explore whether the thermal isomerisation performance of some of the fastest available motors of this type can be further improved by reducing the sizes of the motor halves. Presenting three new redesigned motors that combine an indanylidene rotator with a cyclohexadiene, pyran or thiopyran stator, we first use multiconfigurational quantum chemical methods to verify that the photoisomerisations of these motors sustain unidirectional rotary motion. Then, by performing density functional calculations, we identify both stepwise and concerted mechanisms for the thermal isomerisations of the motors and show that the rate-determining free-energy barriers of these processes are up to 25 kJ mol(-1) smaller than those of the original motors. Furthermore, the thermal isomerisations of the redesigned motors proceed in fewer steps. Altogether, the results suggest that the redesigned motors are useful templates for improving the thermal isomerisation performance of existing overcrowded alkene-based motors.

  6. Construction of a dead-end type micro- to R.O. membrane test cell and performance test with the laboratory- made and commercial membranes

    Darunee Bhongsuwan


    Full Text Available A dead-end type membrane stirred cell for an RO filtration test has been designed and constructed. Magnetic stirring system is applied to overcome a pressure-induced concentration polarization occurred over a membrane surface in the test cell. A high pressure N2 tank is used as a pressure source.Feed container is designed for 2.5 l feed solution and a stirred cell volume is 0.5 l . The test cell holds a magnetic stirrer freely moved over the membrane surface. All units are made of stainless steel. A porous SS316L disc is used as a membrane support. The dead-end stirred cell is tested to work properly in an operating pressure ranged 0 - 400 psi. It means that the dead-end cell can be used to test a membrane of different filtration modes, from micro- to Reverse Osmosis filtration. Tests performed at 400 psi for 3 hours are safe but tests at a 500 psi increase leakage possibility. The cell is used to test the performance of both commercial and laboratory-made membranes. It shows that the salt rejection efficiency of the nano- and RO membranes, NTR759HR and LES90, determined by using the new test cell, is closely similar to those reported from the manufacture. Result of the tests for our own laboratory-made membrane shows a similar performance to the nanofiltration membrane LES90.

  7. The benefits of redesigning Benin's vaccine supply chain.

    Brown, Shawn T; Schreiber, Benjamin; Cakouros, Brigid E; Wateska, Angela R; Dicko, Hamadou M; Connor, Diana L; Jaillard, Philippe; Mvundura, Mercy; Norman, Bryan A; Levin, Carol; Rajgopal, Jayant; Avella, Mélanie; Lebrun, Caroline; Claypool, Erin; Paul, Proma; Lee, Bruce Y


    New vaccine introductions have put strains on vaccine supply chains around the world. While increasing storage and transportation may be the most straightforward options, it is also important to consider what financial and operational benefits can be incurred. In 2012, suboptimal vaccine coverage and impending vaccine introductions prompted the Republic of Benin's Ministry of Health (MOH) to explore ways to improve their vaccine supply chain. Working alongside the Beninese MOH, we utilized our computational model, HERMES, to explore the impact on cost and vaccine availability of three possible options: (1) consolidating the Commune level to a Health Zone level, (2) removing the Commune level completely, and (3) removing the Commune level and expanding to 12 Department Stores. We also analyzed the impact of adding shipping loops during delivery. At baseline, new vaccine introductions without any changes to the current system increased the logistics cost per dose ($0.23 to $0.26) and dropped the vaccine availability to 71%. While implementing the Commune level removal scenario had the same capital costs as implementing the Health Zone scenario, the Health Zone scenario had lower operating costs. This increased to an overall cost savings of $504,255 when implementing shipping loops. The best redesign option proved to be the synergistic approach of converting to the Health Zone design and using shipping loops (serving ten Health Posts/loop). While a transition to either redesign or only adding shipping loops was beneficial, implementing a redesign option and shipping loops can yield both lower capital expenditures and operating costs.

  8. Facile conversion of commercial coarse-type LiCoO2 to nanocomposite-separated nanolayer architectures as a way for electrode performance enhancement.

    Zhao, Yinan; Sha, Yujing; Lin, Qian; Zhong, Yijun; Tade, Moses O; Shao, Zongping


    Coarse-type LiCoO2 is the state-of-the-art cathode material in small-scale lithium-ion batteries (LIBs); however, poor rate performance and cycling stability limit its large-scale applications. Here we report the modification of coarse-type LiCoO2 (LCO) with nanosized lithium lanthanum titanate (Li3xLa2/3-xTiO3, LLTO) through a facile sol-gel process, the electrochemical performance of commercial LiCoO2 is improved effectively, in particular at high rates. The crystalline structure of pristine LiCoO2 is not affected by the introduction of the LLTO phase, while nanosized LLTO particles are likely incorporated into the space of the LiCoO2 layers to form a LCO-LLTO nanocomposite, which separate the LCO layers with the increase of layer spacing to ∼100 nm. The LLTO incorporation through the facile post-treatment effectively reduces the charge-transfer resistance and increases the electrode reactions; consequently, the LLTO-incorporated LCO electrode shows higher capacity than LiCoO2 at a higher rate and prolonging cycling stability in both potential ranges of 2.7-4.2 V and 2.7-4.5 V, making it also suitable for high-rate operation. This novel concept is general, which may also be applicable to other electrode materials. It thus introduces a new way for the development of high rate-performance electrodes for LIBs for large scale applications such as electric vehicles and electrochemical energy storage for smart grids.

  9. Control of manual lifting hazards: II. Job redesign.

    Ayoub, M A


    Job content and workplace components can be altered to assure that lifting stresses remain within the acceptable limits defined for the industrial population-at-large. The plan for redesign advocates (1) maintaining the weight handled within the recommended limits; (2) modifying the workplace to enhance postural stability and to avoid handling weights and excessive physical loading; and (3) increasing available job time by reducing frequency of lifts and/or introducing appropriate rest periods. Limits recommended by the National Institute for Occupational Safety and Health on acceptable loads are reviewed.

  12. Efficacy and safety of proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors, alirocumab and evolocumab, a post-commercialization study.

    Choi, Joshua; Khan, Amir M; Jarmin, Michael; Goldenberg, Naila; Glueck, Charles J; Wang, Ping


    Efficacy-safety of proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors, alirocumab (ALI) and evolocumab (EVO), have previously been evaluated through controlled clinical trials with selective patient groups. Post-commercially, in 69 patients with heterozygous familial hypercholesterolemia (HeFH) and/or cardiovascular disease (CVD) with suboptimal LDL cholesterol (LDLC) lowering on maximal tolerated LDLC therapy, we assessed efficacy and safety of ALI and EVO. Post-commercially, we started 29 patients on ALI 75 mg, 18 on ALI 150 mg, and 22 on EVO 140 mg every 2 weeks added to a maximally tolerated LDLC-lowering regimen. Since LDLC lowering did not differ between ALI 150 and EVO 140 mg, ALI 150-EVO 140 data were pooled (ALI-EVO). Changes in LDLC and AHA and NIH calculated 10-year CVD risks were assessed. Of the 69 patients, 25 had HeFH, 25 CVD, and 19 had both. At entry, 23 (33%) took statins and 46 (67%) were statin-intolerant. Mean ± SD and median follow-up were 49 ± 13 and 49 weeks on ALI 75 mg, and 37 ± 12 and 33 weeks on ALI-EVO. In the ALI-EVO group (n = 40), median LDLC fell from 165 mg/dl at entry to 70 mg/dl (median - 59%, p  0.05) between ALI 75 mg and ALI-EVO. In patients with HeFH and/or CVD, LDLC decreased from 115 to 68 mg/dl (39%) on ALI 75 mg with mean follow-up of 49 weeks, and from 165 to 70 mg/dl (59%) on ALI-EVO over 37 weeks, p < .0001 for both. Adverse events were minimal and tolerable. ALI and EVO represent paradigm shifts in LDLC lowering.

  13. Redesign of a supply network by considering stochastic demand

    Juan Camilo Paz


    Full Text Available This paper presents the problem of redesigning a supply network of large scale by considering variability of the demand. The central problematic takes root in determining strategic decisions of closing and adjusting of capacity of some network echelons and the tactical decisions concerning to the distribution channels used for transporting products. We have formulated a deterministic Mixed Integer Linear Programming Model (MILP and a stochastic MILP model (SMILP whose objective functions are the maximization of the EBITDA (Earnings before Interest, Taxes, Depreciation and Amortization. The decisions of Network Design on stochastic model as capacities, number of warehouses in operation, material and product flows between echelons, are determined in a single stage by defining an objective function that penalizes unsatisfied demand and surplus of demand due to demand changes. The solution strategy adopted for the stochastic model is a scheme denominated as Sample Average Approximation (SAA. The model is based on the case of a Colombian company dedicated to production and marketing of foodstuffs and supplies for the bakery industry. The results show that the proposed methodology was a solid reference for decision support regarding to the supply networks redesign by considering the expected economic contribution of products and variability of the demand.

  14. Digital prototyping technique applied for redesigning plastic products

    Pop, A.; Andrei, A.


    After products are on the market for some time, they often need to be redesigned to meet new market requirements. New products are generally derived from similar but outdated products. Redesigning a product is an important part of the production and development process. The purpose of this paper is to show that using modern technology, like Digital Prototyping in industry is an effective way to produce new products. This paper tries to demonstrate and highlight the effectiveness of the concept of Digital Prototyping, both to reduce the design time of a new product, but also the costs required for implementing this step. The results of this paper show that using Digital Prototyping techniques in designing a new product from an existing one available on the market mould offers a significantly manufacturing time and cost reduction. The ability to simulate and test a new product with modern CAD-CAM programs in all aspects of production (designing of the 3D model, simulation of the structural resistance, analysis of the injection process and beautification) offers a helpful tool for engineers. The whole process can be realised by one skilled engineer very fast and effective.

  15. Business Process Redesign Using EDI: the BHP steel experience

    Paula Swatman


    Full Text Available EDI should not be seen as a competitive weapon - it does not offer a sustainable competitive advantage to its users as did the earlier inter-organisational systems (such as the various airline reservation systems. Instead EDI provides a standardised infrastructure upon which an adopting organisation can reengineer its business processes and thus confers a long-term, strategic and comparative advantage upon such an adopter. The potential for sustained competitive advantage to be derived from EDI arises from its integration with the organisational structure of its implementor, depending upon the implementing organisation's ability to redesign its business processes appropriately. This paper examines the case of (arguably the most sophisticated EDI-using company in Australia, BHP Steel, demonstrating the advantages obtainable by an organisation using EDI as a foundation for its reengineered organisational structure and business processes and concludes that: • there are real benefits to be obtained from an inter organisational electronic trading strategy founded on EDI as the enabling mechanism - benefits which are considerably more extensive than EDI's comparatively simple technical nature would appear to offer; • organisational gateways utilising an Application Generic approach to system integration and isolating the communications issue by insisting on the use of international data communications standards do offer a realistic and successful solution to the problem of internal and external trade for large and sophisticated organisations; • the majority of these achievements would have been either unlikely or totally impossible without BHP Steel's commitment to organisation-wide Business Process Redesign.

  16. Redesigning of Shopping Cart for Cost Reduction Using DFMA

    Naiju C. D.


    Full Text Available Product Design is a way of creating new designs for various products to be sold by a business to customers. It is very efficient as certain new designs and ideas can lead to products with less cost. The two methodologies of design for manufacture and assembly (DFMA include design for manufacture (DFM which is concentrated on reducing the number of redundant parts for the ease of manufacturing and also design for assembly (DFA which is concentrated on reducing the assembly time of the parts included in the design of the product. It also helps to reduce the inefficiency and waste in the product design. This paper includes a case study of manufacture and assembly costs estimation of a shopping cart which is widely used in supermarkets, department stores all around the world. The main aim of this paper is to reduce the overall manufacturing cost of the shopping cart. The CAD model of the different parts of the shopping cart was generated using solid works and then analysed using the DFMA software. The outcomes were studied and the re-design is done. The final assembly cost of the re-designed product was compared to that of the existing design and the results are discussed.

  7. Re-Designing a School Library Media Center for the 21st Century

    Moyer, Mary; Baker, Rosalie M.


    The School Library Media Center at Delsea Regional High School was not meeting the needs of the students, staff and community of the 21st century and hence a re-design of the library space was needed. The re-design project included planning objectives, providing a scale drawing and involving key players as stakeholders.

  8. Navigating User Feedback Channels to Chart an Evidence Based Course for Library Redesign

    T. Derek Halling


    Full Text Available Objectives – The objective of this project was to redesign library spaces based on the user feedback obtained from a broad complement of feedback channels. The over-arching goal of this project was to develop an evidence based approach to the redesign of library spaces.Methods – Data from user-initiated and library-initiated feedback channels were collected and analyzed to determine priorities for library space changes. Online/onsite suggestions, a library onsite census survey, the LibQUAL+® survey, a whiteboard, ballot voting, and text voting were all used to gather input. A student advisory group was used as a sounding board for planned space changes before a final decision was made.Results – Data produced by different feedback channels varied both in the number of suggestions generated as well as the changes requested. Composite data from all feedback channels resulted in a total of 687 suggestions identifying 17 different types of space changes. An onsite whiteboard, the LibQUAL+® survey, and library census proved the most prolific in producing suggestions.Conclusion – Priorities for space changes were best determined through a composite of suggestions received from all feedback channels. The number of suggestions and requests received that were initiated by users was so small that it had to be supplemented with library-initiated feedback requests. The use of multiple feedback channels enhanced the number, variety, and scope of the suggestions that were received. Similar requests received through multiple feedback channels emphasized their importance to users. Focused follow-up feedback channels were effective in clarifying user suggestions for specific changes.

  9. Numerical Analysis of the Turbine 99 Draft Tube Flow Field Provoked by Redesigned Inlet Velocity Profiles.

    Galván, S.; Reggio, M.; Guibault, F.; Castro, L.


    In recent years, several investigations on hydraulic turbine draft tube performance have shown that the hydrodynamic flow field at the runner outlet determines the diffuser efficiency affecting the overall performance of the turbine. This flow field, for which the principal characteristics are the flow rate and the inlet swirling flow intensity, is mostly developed on turbines designed for low head (high specific velocity) and operated away from their best efficiency point. To identify factors of the flow field responsible for loosing draft- tube efficiency, the correlations between the flow pattern along the diffuser and both swirl intensity and flow rate have been examined. An analytical representation of inlet flow field has been manipulated by a Multi Island Genetic Algorithm through the automatic coupling of multidisciplinary commercial software systems in order to obtain redesigned inlet velocity profiles. This loop allowed determining the profile for which the minimum energy loss factor was reached. With different flow field patterns obtained during the optimization process it was possible to undertake a qualitative and quantitative analysis which has helped to understand how to suppress or at least mitigate undesirable draft tube flow characteristics. The direct correlation between the runner blade design and the kinematics of the swirl at the draft tube inlet should suppose the perfect coupling at the runner-draft tube interface without compromising the overall flow stability of the machine.

  10. Implementing Business Process Redesign: early lessons from the Australian experience

    Marianne Broadbent


    Full Text Available Business Process Redesign (BPR is a change management approach aimed at achieving quantum improvements in business performance. Industry interest levels in BPR are high as a direct result of current difficulties in the global economic climate and tight business conditions. Integral to BPR is the availability of new stable technologies which both stimulate and enable process changes. This paper highlights the experiences of a number of Australian firms which have implemented BPR. A ten step framework for BPR is presented together with a series of caveats. BPR is a difficult, messy and often non-linear activity which challenges many of the ways organisations operate. Information Technology plays a pivotal role in BPR as both an enabler and disenabler for change. Lessons emerging from early Australian experiences with BPR focus on the role of executive sponsorship, consultants, measurements, education and training, technology and people involved in the change process.

  11. Does Our English Teacher Education Need Re-Designing?

    J. Bismoko


    Full Text Available Change has been regarded as inherent in any living organization for quite a long time, for its own development and to keep up its external relevance as part of the development. Individual or random responses to external sources for change, however, tend to cause internal inconsistency and inefficiency. On this occasion a number of current issues, potential to be sources for change, such as diversified outcomes, the school-based management, and the competence-based curriculum will be looked over in terms of its relevance to our English-teacher education. There are obviously other sources of change, and they will keep coming in, but when we feel they become too many, and they come too often, it is time to read between the lines, to grab their underlying spirit. Perhaps the time is here for us to get our English-teacher education re-orientated, and subsequently re-designed.

  12. Redesigning a Flexible Material Master Data Application with Language Dependency

    Mihaela Muntean


    Full Text Available Based on some inconveniences identified within a material master data application of theSAP MM module, the current paper proposes an alternative technical solution for designing thepopup layout screen of the material master data application with respect to language dependency.The application should present the text of all tabs, areas and fields in the desired language based onthe user logon preferences. Also it has been implemented a possibility to sort the data in the desiredorder, so the customer isn’t forced, as before, to search for a certain field, when updating certainmaterials. The proposed solution suggests the use of five database tables, combined within threemaintenance views, which build a view cluster. The advantage of the redesigned application consistsof easier maintainability of the data (fields, areas and tabs can be easily added, deleted, reorderedand renamed and all the data within the view cluster can be translated into any language supportedby the system.

  13. Redesigning Systems of Care for Older Adults with Alzheimer' Disease

    Callahan, Christopher M.; Sachs, Greg A.; LaMantia, Michael A.; Unroe, Kathleen T.; Arling, Greg A.; Boustani, Malaz A.


    The basic principle of care for patients with Alzheimer's disease is support for a patient-caregiver dyad. Any model of care seeking to improve the quality, efficiency, or cost of care for persons with Alzheimer's disease must attend to this principle. Models of care seeking to support this dyad began with strategies focusing mainly on the family caregiver. These models have grown in complexity to encompass team-based care that seeks to coordinate care across settings and providers of care for a defined population of patients. Most Americans in most communities, however, do not have access to these best practices models. While the effectiveness of new models of care is evidence-based, there are multiple barriers to widespread adoption including workforce limitations and the cost of practice redesign. We review the origins and content of current models and describe early efforts to improve their implementation on a broader scale. PMID:24711324

  14. Redesign of an Exhaust Gas Economiser Using Software

    Balaji, R.


    Approaches to heat exchanger designs are numerous. Marine heat exchangers are usually single and they do not form part of a large network. Selections are generally based on the duties, area and the heat quantum. Over capacities and un-optimised designs could result. As an exercise to verify the choice, an existing heat exchanger on board of an operational ship was redesigned using computer software with thermodynamic data and standard geometric values. The formulae employed in the software were extracted and verified. The geometric data was used to develop the design drawings using SolidWorks®. Visualising the designs, the physical arrangement was improved. Comparisons and design improvements were made keeping the standard values in view. With the exercises, a method of developing an optimised physical design reducing the number of rating runs has been demonstrated.

  15. Quality evaluation of terpinen-4-ol-type Australian tea tree oils and commercial products: an integrated approach using conventional and chiral GC/MS combined with chemometrics.

    Wang, Mei; Zhao, Jianping; Avula, Bharathi; Wang, Yan-Hong; Chittiboyina, Amar G; Parcher, Jon F; Khan, Ikhlas A


    GC/MS, chiral GC/MS, and chemometric techniques were used to evaluate a large set (n=104) of tea tree oils (TTO) and commercial products purported to contain TTO. Twenty terpenoids were determined in each sample and compared with the standards specified by ISO-4730-2004. Several of the oil samples that were ISO compliant when distilled did not meet the ISO standards in this study primarily due to the presence of excessive p-cymene and/or depletion of terpinenes. Forty-nine percent of the commercial products did not meet the ISO specifications. Four terpenes, viz., α-pinene, limonene, terpinen-4-ol, and α-terpineol, present in TTOs with the (+)-isomer predominant were measured by chiral GC/MS. The results clearly indicated that 28 commercial products contained excessive (+)-isomer or contained the (+)-isomer in concentrations below the norm. Of the 28 outliers, 7 met the ISO standards. There was a substantial subset of commercial products that met ISO standards but displayed unusual enantiomeric+/-ratios. A class predictive model based on the oils that met ISO standards was constructed. The outliers identified by the class predictive model coincided with the samples that displayed an abnormal chiral ratio. Thus, chiral and chemometric analyses could be used to confirm the identification of abnormal commercial products including those that met all of the ISO standards.

  16. An institutionwide approach to redesigning management of cardiopulmonary resuscitation.

    Lighthall, Geoffrey K; Mayette, Michael; Harrison, T Kyle


    Despite widespread training in basic life support (BLS) and advanced cardiovascular life support (ACLS) among hospital personnel, the likelihood of survival from in-hospital cardiac arrests remains low. In 2006 a university-affiliated tertiary medical center initiated a cardiopulmonary (CPR) resuscitation redesign project. REDESIGNING THE HOSPITAL'S RESUSCITATION SYSTEM: The CPR Committee developed the interventions on the basis of a large-scale view of the process of delivering BLS and ACLS, identification of key decision nodes and actions, and compartmentalization of specific functions. It was proposed that arrest management follow a steady progression in a two-layer scheme from BLS to ACLS. Handouts describing team structure and specific roles were given to all code team providers and house staff at the start of their month-long rotations. To further increase role clarity and team organization, daily morning and evening meetings of the arrest team were instituted. Site-specific BLS training, on-site ACLS refresher training, and defibrillator training were initiated. Project elements also included use of unannounced mock codes to provide system oversight; preparation and distribution of cognitive aids (printed algorithms, dosing guides, and other checklists to ensure compliance with ACLS protocols), identification of patients who may be unstable or a source of concern, event review and analysis of arrests and other critical events, and a CPR website. A mature hospital-based resuscitation system should include definition of arrest trends and resuscitation needs, development of local methods for approaching the arresting patient, an emphasis on prevention, establishment of training programs tailored to meet specific hospital needs, system examination and oversight, and administrative processes that maximize interaction between all components.

  17. RENEW—a renal redesign project in predialysis patient care

    Sau Fan Chow, Josephine; Jobburn, Kim; Chapman, Margaret; Suranyi, Michael


    Background An ageing population and geographical growth, along with an increase in the number of people that reside in specific location, are increasing the demand for renal replacement therapies. Hospital-based haemodialysis units are struggling to cope with the associated physical, staffing and cost demands. Home-based dialysis therapies are known to be more cost effective with superior social, physical health and survival outcomes. Methods ‘RENEW, a renal redesign project, examined the pre-dialysis health care experience of renal patients to find opportunities to improve patient care outcomes and increase the uptake of home-based dialysis therapies. This article details two crucial parts of the approach to change management: (i) diagnostics—an inclusive, client focused, multidisciplinary approach to identify issues relating to the pre-dialysis journey—and (ii) solution design—an inclusive problem-solving approach to identify and marry solutions to the issues identified during diagnostics. Results Based on feedback from patients/caregivers and staff interviews, utilizing a clinical redesign methodology, a new model of care was developed, implemented and subsequently embedded into clinical practice. The results have been evident via improved care coordination, enhanced patient preparation for dialysis, improved patient psychosocial welfare and, importantly, an increased number of patients planned for and commencing home dialysis. This has empowered patients by giving them the confidence, knowledge and skills to be actively engaged in their own care. The project resulted in significant expenditure avoidance. Conclusion Change management strategies with successful implementation are vital components of evolving clinical practice to achieve both clinical and organizational goals. PMID:27679723

  18. Redesigning mental healthcare delivery: is there an effect on organizational climate?

    Joosten, T C M; Bongers, I M B; Janssen, R T J M


    Many studies have investigated the effect of redesign on operational performance; fewer studies have evaluated the effects on employees' perceptions of their working environment (organizational climate). Some authors state that redesign will lead to poorer organizational climate, while others state the opposite. The goal of this study was to empirically investigate this relation. Organizational climate was measured in a field experiment, before and after a redesign intervention. At one of the sites, a redesign project was conducted. At the other site, no redesign efforts took place. Two Dutch child- and adolescent-mental healthcare providers. Professionals that worked at one of the units at the start and/or the end of the intervention period. The main intervention was a redesign project aimed at improving timely delivery of services (modeled after the breakthrough series). Scores on the four models of the organizational climate measure, a validated questionnaire that measures organizational climate. Our analysis showed that climate at the intervention site changed on factors related to productivity and goal achievement (rational goal model). The intervention group scored worse than the comparison group on the part of the questionnaire that focuses on sociotechnical elements of organizational climate. However, observed differences were so small, that their practical relevance seems rather limited. Redesign efforts in healthcare, so it seems, do not influence organizational climate as much as expected.

  20. Time-driven activity-based costing: a driver for provider engagement in costing activities and redesign initiatives.

    McLaughlin, Nancy; Burke, Michael A; Setlur, Nisheeta P; Niedzwiecki, Douglas R; Kaplan, Alan L; Saigal, Christopher; Mahajan, Aman; Martin, Neil A; Kaplan, Robert S


    To date, health care providers have devoted significant efforts to improve performance regarding patient safety and quality of care. To address the lagging involvement of health care providers in the cost component of the value equation, UCLA Health piloted the implementation of time-driven activity-based costing (TDABC). Here, the authors describe the implementation experiment, share lessons learned across the care continuum, and report how TDABC has actively engaged health care providers in costing activities and care redesign. After the selection of pilots in neurosurgery and urology and the creation of the TDABC team, multidisciplinary process mapping sessions, capacity-cost calculations, and model integration were coordinated and offered to engage care providers at each phase. Reviewing the maps for the entire episode of care, varying types of personnel involved in the delivery of care were noted: 63 for the neurosurgery pilot and 61 for the urology pilot. The average cost capacities for care coordinators, nurses, residents, and faculty were $0.70 (range $0.63-$0.75), $1.55 (range $1.28-$2.04), $0.58 (range $0.56-$0.62), and $3.54 (range $2.29-$4.52), across both pilots. After calculating the costs for material, equipment, and space, the TDABC model enabled the linking of a specific step of the care cycle (who performed the step and its duration) and its associated costs. Both pilots identified important opportunities to redesign care delivery in a costconscious fashion. The experimentation and implementation phases of the TDABC model have succeeded in engaging health care providers in process assessment and costing activities. The TDABC model proved to be a catalyzing agent for cost-conscious care redesign.

  1. Redesigning the Medicare inpatient PPS to reduce payments to hospitals with high readmission rates.

    Averill, Richard F; McCullough, Elizabeth C; Hughes, John S; Goldfield, Norbert I; Vertrees, James C; Fuller, Richard L


    A redesign of the Medicare inpatient prospective payment system (IPPS) that reduces payments to hospitals that have high-risk adjusted readmission rates is proposed. The redesigned IPPS uses a readmission performance standard from best practice hospitals to determine the risk-adjusted number of excess readmissions in a hospital and determines the payment reduction for a hospital based on its excess number of readmissions. Extrapolating from Florida Medicare 2004-2005 discharge data, the redesigned IPPS is estimated to reduce overall annual Medicare inpatient expenditures nationally by $1.25, 1.92, and 2.58 billion for readmission windows of 7, 15, and 30 days, respectively.

  2. International Space Station (ISS) Potable Water Dispenser (PWD) Beverage Adapter (BA) Redesign

    Edgerly, Rachel; Benoit, Jace; Shindo, David


    The Potable Water Dispenser used on the International Space Station (ISS) interfaces with food and drink packages using the Beverage Adapter and Needle. Unexpected leakage has been seen in this interface. The Beverage Adapter used on-orbit was returned to the ground for Test, Teardown, and Evaluation. The results of that investigation prompted a redesign of the Beverage Adapter and Needle. The Beverage Adapter materials will be changed to be more corrosion resistant, and the Needle will be redesigned to preclude leakage. The redesigns have been tested and proven.

  3. Evaluating a Redesigned Large-enrollment Introductory Science Survey Course

    Slater, Timothy F.; Slater, S. J.; Lyons, D. J.; in Astronomy, Cognition; Physics; Earth sciences Research CAPER Team


    Over the past two years, faculty in the we have engaged in a major course redesign effort for the undergraduate general education science requirement with the goal of improving student learning and attitudes while, at the same time, dramatically reducing costs of offering such a course. Using a reformed teaching framework of learner-centered education, the large-enrollment, introductory geosciences survey course was overhauled to include interactive lectures, just-in-time online quizzes, a next-generation textbook, and weekly discussions lead by graduate students and undergraduate peer mentors. We used a 2-group, pre-post, multiple-measures, mixed-method quasi-experimental study design. The Geosciences Concept Inventory (GCI) was given as a pre-test/post-test to students in the pre-modified course and the reformed course to compare student learning in terms of gain scores. Students in the unmodified course had a pre-test GCI percentage correct of 28.67 (SD=11.45, n=96) which increased to 45.26 (SD=11.76, n=84) on the post-test. After course redesign, students had a pre-test GCI percentage correct of 38.62 (SD=8.42, n=144) which increased a post-test GCI score of 48.73 (SD=7.49, n=132). In a similar way, the Likert-style Attitudes Toward Science Survey was given as an end-of-class post-test to students in the pre-modified course and as a pre-test/post-test the reformed course to compare student attitudes between the courses. The average ranking on a 5-point scale as a pre-test was 3.454 (SD=1.259, n=508) whereas the post-tests for the unmodified course was 3.49 (SD=1.05, n=101) and 3.50 (SD=1.127, n=369) for the reformed course. As is commonly observed in many instances, there are no statistical differences evident among the survey results. In contrast, 14 hours of interview and focus group transcripts reveal that students find the reformed course to be relevant to their lives and educationally satisfying, both of which are infrequently observed among traditional

  4. Lean thinking across a hospital: redesigning care at the Flinders Medical Centre.

    Ben-Tovim, David I; Bassham, Jane E; Bolch, Denise; Martin, Margaret A; Dougherty, Melissa; Szwarcbord, Michael


    Lean thinking is a method for organising complex production processes so as to encourage flow and reduce waste. While the principles of lean thinking were developed in the manufacturing sector, there is increasing interest in its application in health care. This case history documents the introduction and development of Redesigning Care, a lean thinking-based program to redesign care processes across a teaching general hospital. Redesigning Care has produced substantial benefits over the first two-and-a-half years of its implementation, making care both safer and more accessible. Redesigning Care has not been aimed at changing the specifics of clinical practice. Rather, it has been concerned with improving the flow of patients through clinical and other systems. Concepts that emerged in the manufacturing sector have been readily translatable into health care. Lean thinking may play an important role in the reform of health care in Australia and elsewhere.

  6. Re-designing the PhEDEx Security Model

    C-H, Huang; Wildish, T.; X, Zhang


    PhEDEx, the data-placement tool used by the CMS experiment at the LHC, was conceived in a more trusting time. The security model provided a safe environment for site agents and operators, but offerred little more protection than that. Data was not sufficiently protected against loss caused by operator error or software bugs or by deliberate manipulation of the database. Operators were given high levels of access to the database, beyond what was actually needed to accomplish their tasks. This exposed them to the risk of suspicion should an incident occur. Multiple implementations of the security model led to difficulties maintaining code, which can lead to degredation of security over time. In order to meet the simultaneous goals of protecting CMS data, protecting the operators from undue exposure to risk, increasing monitoring capabilities and improving maintainability of the security model, the PhEDEx security model was redesigned and re-implemented. Security was moved from the application layer into the database itself, fine-grained access roles were established, and tools and procedures created to control the evolution of the security model over time. In this paper we describe this work, we describe the deployment of the new security model, and we show how these enhancements improve security on several fronts simultaneously.

    PhEDEx. the data-placement tool used by the CMS experiment at the LHC, was conceived in a more trusting time. The security model was designed to provide a safe working environment for site agents and operators, but provided little more protection than that.

  8. Activity theory as a framework for analyzing and redesigning work.

    Engeström, Y


    Cultural-historical activity theory is a new framework aimed at transcending the dichotomies of micro- and macro-, mental and material, observation and intervention in analysis and redesign of work. The approach distinguishes between short-lived goal-directed actions and durable, object-oriented activity systems. A historically evolving collective activity system, seen in its network relations to other activity systems, is taken as the prime unit of analysis against which scripted strings of goal-directed actions and automatic operations are interpreted. Activity systems are driven by communal motives that are often difficult to articulate for individual participants. Activity systems are in constant movement and internally contradictory. Their systemic contradictions, manifested in disturbances and mundane innovations, offer possibilities for expansive developmental transformations. Such transformations proceed through stepwise cycles of expansive learning which begin with actions of questioning the existing standard practice, then proceed to actions of analyzing its contradictions and modelling a vision for its zone of proximal development, then to actions of examining and implementing the new model in practice. New forms of work organization increasingly require negotiated 'knotworking' across boundaries. Correspondingly, expansive learning increasingly involves horizontal widening of collective expertise by means of debating, negotiating and hybridizing different perspectives and conceptualizations. Findings from a longitudinal intervention study of children's medical care illuminate the theoretical arguments.

  9. Redesigning Health Care Practices to Address Childhood Poverty.

    Fierman, Arthur H; Beck, Andrew F; Chung, Esther K; Tschudy, Megan M; Coker, Tumaini R; Mistry, Kamila B; Siegel, Benjamin; Chamberlain, Lisa J; Conroy, Kathleen; Federico, Steven G; Flanagan, Patricia J; Garg, Arvin; Gitterman, Benjamin A; Grace, Aimee M; Gross, Rachel S; Hole, Michael K; Klass, Perri; Kraft, Colleen; Kuo, Alice; Lewis, Gena; Lobach, Katherine S; Long, Dayna; Ma, Christine T; Messito, Mary; Navsaria, Dipesh; Northrip, Kimberley R; Osman, Cynthia; Sadof, Matthew D; Schickedanz, Adam B; Cox, Joanne


    Child poverty in the United States is widespread and has serious negative effects on the health and well-being of children throughout their life course. Child health providers are considering ways to redesign their practices in order to mitigate the negative effects of poverty on children and support the efforts of families to lift themselves out of poverty. To do so, practices need to adopt effective methods to identify poverty-related social determinants of health and provide effective interventions to address them. Identification of needs can be accomplished with a variety of established screening tools. Interventions may include resource directories, best maintained in collaboration with local/regional public health, community, and/or professional organizations; programs embedded in the practice (eg, Reach Out and Read, Healthy Steps for Young Children, Medical-Legal Partnership, Health Leads); and collaboration with home visiting programs. Changes to health care financing are needed to support the delivery of these enhanced services, and active advocacy by child health providers continues to be important in effecting change. We highlight the ongoing work of the Health Care Delivery Subcommittee of the Academic Pediatric Association Task Force on Child Poverty in defining the ways in which child health care practice can be adapted to improve the approach to addressing child poverty.

  10. New Trends for Re-design the IT Companies

    Florin Ionita


    Full Text Available As it is known, the management adaptability to the changes taking place in the environment where it is acting represents a key factor for survival and development of an organization. As a reaction to the external signals, the internal change may be superficial when it affects only the development of activity in different sectors, or might be profound, when it changes the main processes and rules of the business and even the philosophy of the company’s existence. Speaking about structural changes, one of the most common approaches of the modern management is the re-design of the business architecture. The new architectural models such as Service Oriented Architecture (SOA, presented in this paper, come with important advantages, but their implementation is not always very easy. This paper tries to present some of the most common encountered contextual characteristics which are able to start the implementation of Service Oriented Architecture, some advantages of this concept as well as some practical approaches of implementing.

  11. Redesigning assembly stations using ergonomic methods as a lean tool.

    Eswaramoorthi, M; John, Mervyn; Rajagopal, C Arjun; Prasad, P S S; Mohanram, P V


    With the current state of the global economy, demand for various products plummeting. To sustain in the market, companies have to reduce cost and improve quality. Today, companies have started implementing new philosophies like TQM, TPM, six sigma and lean manufacturing techniques to remain competitive in the market. Lean manufacturing is an emerging philosophy which continuously strives to reduce waste. The main objective of analyzing the assembly line with a lean perspective is to identify the areas related to human interface with other systems that could lead to the generation of waste. Improper workplace design leads to unreasonable mental or physical burden and results in waste generation like slow work (delay and inventory), and defects, which is named as muri waste. An attempt has been made in this paper to locate muri waste and create a "Lean assembly line". The proposed method, based on the use of Rapid Upper Limb Assessment (RULA) with CATIA V5 platform, has allowed the measurement of a large set of operator posture parameters and assessment of ergonomic stresses. Based on the results, the process stations in the assembly line were redesigned to prevent the generation of waste.

  12. From Telecourses to Online Courses: A Story of Redesign | Du cours télévisé au cours en ligne : une histoire de redesign

    Claude Potvin


    Full Text Available This case deals with the redesign of a standard telecourse - printed material, professional studio video recordings and phone tutoring – into an online course. The redesign involved an adjunct professor in the Humanities having some experience in distance education but little with learning technologies. It was a two-year project including the grant application process. The main issues included replacing television-based content with multimedia content; understanding the complexity of interactions between materials, students, and tutors; and adapting traditional assessment approaches to online instruments and methods.

  17. The change initiative diamond : a framework to balance business process redesign with other change initiatives

    Price, Janet; BRAGANZA Ashley; Weiss, Oscar


    In many organisations radical change towards a process orientation, often termed Business Process Redesign/Re-engineering (BPR), is being undertaken with the aim of achieving very significant improvements in performance. Often scholars and consultants suggest that managers should base their redesign efforts on a ‘clean sheet’ view of the organisation. There appears to be an implicit assumption that BPR initiatives will take place in organisations where no other changes are in p...

    Kalmiş, Erbil; Azbar, Nuri; Kalyoncu, Fatih


    Biological decolorization of Benazol Black ZN, a reactive azo-type textile dyestuff, was comparatively studied using 3 different commercial-type white rot fungi strains (Pleurotus ostreatus, Pleurotus cornucopiae var. citrinopileatus, Pleurotus djamor, and 2 wild types of P. ostreatus (MCC07 and MCC20) isolated from the nature. The initial dye concentrations in the medium were 500 and 1000 mg.L-1. All the organisms studied decolorized Benazol Black ZN to varying degrees. At low dye concentration, both commercial and wild type of P. ostreatus resulted in the best decolorization, conversely, wild-type P. ostreatus (MCC07) was found to be much more robust against increasing dye concentration and provided the best decolorization efficiency at high dye concentration.

  19. Re-Design and Beat Testing of the Man-Machine Integration Design and Analysis System: MIDAS

    Shively, R. Jay; Rutkowski, Michael (Technical Monitor)


    The Man-machine Design and Analysis System (MIDAS) is a human factors design and analysis system that combines human cognitive models with 3D CAD models and rapid prototyping and simulation techniques. MIDAS allows designers to ask 'what if' types of questions early in concept exploration and development prior to actual hardware development. The system outputs predictions of operator workload, situational awareness and system performance as well as graphical visualization of the cockpit designs interacting with models of the human in a mission scenario. Recently, MIDAS was re-designed to enhance functionality and usability. The goals driving the redesign include more efficient processing, GUI interface, advances in the memory structures, implementation of external vision models and audition. These changes were detailed in an earlier paper. Two Beta test sites with diverse applications have been chosen. One Beta test site is investigating the development of a new airframe and its interaction with the air traffic management system. The second Beta test effort will investigate 3D auditory cueing in conjunction with traditional visual cueing strategies including panel-mounted and heads-up displays. The progress and lessons learned on each of these projects will be discussed.

  2. Concept for the redesign of ECOMAN (standby losses) - Final report; Konzepte fuer Redesign ECOMAN (Standby-Verluste) - Schlussbericht

    Ernst, D.; Haerri, V.V.; Riesen, H.


    A lot of electronic devices are equipped with a so called standby mode. In this mode a device can easily be brought into full functionality directly, by remote control or by timer. Unfortunately, the standby mode implies a high consumption of electrical energy that could be reduced 10 to 20 times by an adequate technology. In Switzerland these losses amount to approximately 1,900 GWh. The so called ECOMAN is an electronic device which can reduce these losses effectively and comfortably. Due to political pressure the producers of electronic devices are forced to find solutions for the problem of standby losses. The ECOMAN would thus be of less importance because the problem would be solved at its roots. This fact and the wish to have a better performance led to a new definition of this device. The ECOMAN has to be improved and shall offer additional functions. E.g. it shall protect the devices from fire hazard or serve as control in the field of building automation. The new concepts were well accepted by the producer who already realized the specification of the first phase of redesign, which serves as basis for the further development of integration. (author)

  3. Redesigning a Large Lecture Course for Student Engagement: Process and Outcomes

    Leslie F. Reid


    Full Text Available Using an action-research approach, a large-lecture science course (240 students was redesigned to improve student engagement in the areas of active and collaborative learning, faculty-student interaction and level of academic challenge. This was mainly achieved through the addition of a half-semester long group project, which replaced half of the lectures and the final exam. The course redesign did not result in more hours spent on teaching and teaching-related activities (grading, assessment preparation, lecturing, lecture preparation for the instructor – although the redesigned course requires the support of teaching assistants for the project component. Data on students’ perceptions of the modified course and the frequency to which they participated in the engagement activities were collected using the Classroom Survey of Student Engagement (CLASSE. The majority of students reported high levels of engagement in most of the intended areas and were comfortable with the new class design. The CLASSE data also helped identify areas where intended engagement levels were not met. These areas are the focus for future course development and action research questions.Utilisant une approche de type recherche-action, un cours de science offert dans un grand auditorium (240 étudiants a été reconfiguré afin d’amener les étudiants à s’engager davantage dans un apprentissage actif et collaboratif ainsi que dans leur interaction professeur-étudiants et à relever un défi de nature académique. Pour ce faire, la moitié des cours magistraux ainsi que l’examen final ont été remplacés par un projet de groupe. La reconfiguration du cours ne s’est pas traduite par une augmentation des heures d’enseignement ou des activités liées à l’enseignement (notation, préparation des évaluations, exposé magistral, préparation de l’exposé magistral – bien qu’elle ait nécessité le soutien des assistants à l’enseignement pour la

  5. Application of an artificial neural network and morphing techniques in the redesign of dysplastic trochlea.

    Cho, Kyung Jin; Müller, Jacobus H; Erasmus, Pieter J; DeJour, David; Scheffer, Cornie


    Segmentation and computer assisted design tools have the potential to test the validity of simulated surgical procedures, e.g., trochleoplasty. A repeatable measurement method for three dimensional femur models that enables quantification of knee parameters of the distal femur is presented. Fifteen healthy knees are analysed using the method to provide a training set for an artificial neural network. The aim is to use this artificial neural network for the prediction of parameter values that describe the shape of a normal trochlear groove geometry. This is achieved by feeding the artificial neural network with the unaffected parameters of a dysplastic knee. Four dysplastic knees (Type A through D) are virtually redesigned by way of morphing the groove geometries based on the suggested shape from the artificial neural network. Each of the four resulting shapes is analysed and compared to its initial dysplastic shape in terms of three anteroposterior dimensions: lateral, central and medial. For the four knees the trochlear depth is increased, the ventral trochlear prominence reduced and the sulcus angle corrected to within published normal ranges. The results show a lateral facet elevation inadequate, with a sulcus deepening or a depression trochleoplasty more beneficial to correct trochlear dysplasia.

  6. Shuttle Redesigned Solid Rocket Motor aluminum oxide investigations

    Blomshield, Fred S.; Kraeutle, Karl J.; Stalnaker, Richard A.


    During the launch of STS-54, a 15 psi pressure blip was observed in the ballistic pressure trace of one of the two Space Shuttle Redesigned Solid Rocket Motors (RSRM). One possible scenario for the observed pressure increase deals with aluminum oxide slag formation in the RSRM. The purpose of this investigation was to examine changes which may have occurred in the aluminum oxide formation in shuttle solid propellant due to changes in the ammonium perchlorate. Aluminum oxide formation from three propellants, all having the same formulation, but containing ammonium perchlorate from different manufacturers, will be compared. Three methods have been used to look for possible differences among the propellants. The first method was to examine window bomb movies of the propellants burning at 100, 300 and 600 psia. The motor operating pressure during the pressure blip was around 600 psia. The second method used small samples of propellant which were fired in a combustion bomb which quenched the burning aluminum particles soon after they left the propellant surface. The bomb was fired in both argon and Nitrogen atmospheres at various pressures. Products from this device were examined by optical microscopy. The third method used larger propellant samples fired into a particle collection device which allowed the aluminum to react and combust more completely. This device was pressurized with Nitrogen to motor operating pressures. The collected products were subdivided into size fractions by screening and sedimentation and analyzed optically with an optical microscope. the results from all three methods indicate very small changes in the size distribution of combustion products.

  7. Commercialization of nanotechnology.

    Hobson, David W


    The emerging and potential commercial applications of nanotechnologies clearly have great potential to significantly advance and even potentially revolutionize various aspects of medical practice and medical product development. Nanotechnology is already touching upon many aspects of medicine, including drug delivery, diagnostic imaging, clinical diagnostics, nanomedicines, and the use of nanomaterials in medical devices. This technology is already having an impact; many products are on the market and a growing number is in the pipeline. Momentum is steadily building for the successful development of additional nanotech products to diagnose and treat disease; the most active areas of product development are drug delivery and in vivo imaging. Nanotechnology is also addressing many unmet needs in the pharmaceutical industry, including the reformulation of drugs to improve their bioavailability or toxicity profiles. The advancement of medical nanotechnology is expected to advance over at least three different generations or phases, beginning with the introduction of simple nanoparticulate and nanostructural improvements to current product and process types, then eventually moving on to nanoproducts and nanodevices that are limited only by the imagination and limits of the technology itself. This review looks at some recent developments in the commercialization of nanotechnology for various medical applications as well as general trends in the industry, and explores the nanotechnology industry that is involved in developing medical products and procedures with a view toward technology commercialization.

  8. New Phenomenon of Commercial Corruption

    Krzysztof Nowakowski


    Full Text Available This article is about increase corruption in private sector as commercial corruption. This establishes a wide understanding of that phenomenon in social science and law. Corruption and bribery are types of fraud and are linked with the private sector too. Although certain types of corruption will decline as the private sector grows and consolidates, other new types involving private sector firms may increase. The commercial corruption can be described as relation inside of an organization and as relation between firms. Corruption in private sector in Poland is connected with social distrust and specific organizational culture, too. Commercial corruption is a familiar feature of their societies and has been the focus of law enforcement and institutional reform. Many others problems do not change the fact that such corruption is a new important problem and causes lost of competitiveness and creates a substitute for fair market and competition in Polish economy and abroad.

  9. Application of participatory ergonomics to the redesign of the family-centred rounds process.

    Xie, Anping; Carayon, Pascale; Cox, Elizabeth D; Cartmill, Randi; Li, Yaqiong; Wetterneck, Tosha B; Kelly, Michelle M


    Participatory ergonomics (PE) can promote the application of human factors and ergonomics (HFE) principles to healthcare system redesign. This study applied a PE approach to redesigning the family-centred rounds (FCR) process to improve family engagement. Various FCR stakeholders (e.g. patients and families, physicians, nurses, hospital management) were involved in different stages of the PE process. HFE principles were integrated in both the content (e.g. shared mental model, usability, workload consideration, systems approach) and process (e.g. top management commitment, stakeholder participation, communication and feedback, learning and training, project management) of FCR redesign. We describe activities of the PE process (e.g. formation and meetings of the redesign team, data collection activities, intervention development, intervention implementation) and present data on PE process evaluation. To demonstrate the value of PE-based FCR redesign, future research should document its impact on FCR process measures (e.g. family engagement, round efficiency) and patient outcome measures (e.g. patient satisfaction).

  10. System redesign of the immunization supply chain: Experiences from Benin and Mozambique.

    Prosser, Wendy; Jaillard, Philippe; Assy, Emmanuelle; Brown, Shawn T; Matsinhe, Graça; Dekoun, Mawutondji; Lee, Bruce Y


    Evidence suggests that immunization supply chains are becoming outdated and unable to deliver needed vaccines due to growing populations and new vaccine introductions. Redesigning a supply chain could result in meeting current demands. The Ministries of Health in Benin in Mozambique recognized known barriers to the immunization supply chain and undertook a system redesign to address those barriers. Changes were made to introduce an informed push system while consolidating storage points, introducing transport loops, and increasing human resource capacity for distribution. Evaluations were completed in each country. Evaluation in each country indicated improved performance of the supply chain. The Effective Vaccine Management (EVM) assessment in Benin documented notable improvements in the distribution criteria of the tool, increasing from 40% to 100% at the district level. In Mozambique, results showed reduced stockouts at health facility level from 79% at baseline to less than 1% at endline. Coverage rates of DTP3 also increased from 68.9% to 92.8%. Benin and Mozambique are undertaking system redesign in order to respond to constraints identified in the vaccine supply chain. Results and learnings show improvements in supply chain performance and make a strong case for system redesign. These countries demonstrate the feasibility of system redesign for other countries considering how to address outdated supply chains. Copyright © 2017 The Author(s). Published by Elsevier Ltd..

    Rosario, Jovy-Anne; Ascher, Marie T; Cunningham, Diana J


    A mobile site redesign was conducted at a medium-sized academic health sciences library with the goal of creating a site that meets the mobile information needs of its users. The redesign phases included (1) needs assessment, (2) usability testing, and (3) site design. The survey results showed that Apple devices were the most prevalent; the most desirable activities performed on a mobile site were searching for articles, accessing full-text articles and e-books, searching databases, and searching the catalog. These activities guided the development of the usability testing tasks and the redesign. All phases were completed within six months, and the total project cost was $50 for incentive purchases.

    Sander, Erik J.; Gosdin, Dennis R.


    Engineers regularly analyze SSME ground test and flight data with respect to engine systems performance. Recently, a redesigned SSME powerhead was introduced to engine-level testing in part to increase engine operational margins through optimization of the engine internal environment. This paper presents an overview of the MSFC personnel engine systems analysis results and conclusions reached from initial engine level testing of the redesigned powerhead, and further redesigns incorporated to eliminate accelerated main injector baffle and main combustion chamber hot gas wall degradation. The conclusions are drawn from instrumented engine ground test data and hardware integrity analysis reports and address initial engine test results with respect to the apparent design change effects on engine system and component operation.

  16. Reinventing the Wheel: One Program's Approach to Redesign of Didactic Courses.

    Hudak, Nicholas M; Scott, Victoria; Spear, Sherrie B; Hills, Karen J


    Curriculum and course redesign are expected and intentional efforts in health professions education. For physician assistant (PA) education, ongoing program self-assessment is a required accreditation standard and may guide deliberate changes within curriculum. The purpose of this article is to describe one PA program’s approach to the redesign of 4 courses into 3 courses that span the entire didactic phase. Significant lessons learned include the importance of planning ahead, identifying key players, documenting the process as part of ongoing self-assessment, competency mapping, and being prepared to make real-time modifications and changes based on course evaluations and faculty feedback. Our approach and guiding principles to the successful redesign of the didactic courses may provide both established and new PA educational programs with useful methods to apply in their own unique curricula.

  17. Robust Backstepping Control Based on a Lyapunov Redesign for Skid-Steered Wheeled Mobile Robots

    Eun-Ju Hwang


    Full Text Available This paper represents a robust backstepping tracking control based on a Lyapunov redesign for Skid‐Steered Wheeled Mobile Robots (WMRs. We present kinematic and dynamic models that explicitly relate the perturbations to the skidding in order to improve the tracking performance during real running. A robust controller is synthesized in the backstepping approach and the Lyapunov redesign technique, which forces the error dynamics to stabilize to the reference trajectories. We design an additional feedback control ‐ a Lyapunov redesign ‐ such that the overall control stabilizes the actual system in the presence of uncertainty and perturbation with the knowledge of the Lyapunov function. Simulation results are provided to validate and analyse the performance and stability of the proposed controller.

  20. Redesign of the CKM RICH velocity spectrometers for use in a 14GHz unseparated beam

    Cooper, Peter S. [Fermi National Accelerator Laboratory, Batavia, IL 60510 (United States)]. E-mail:; Engelfried, Juergen [Universidad Autonoma de San Luis Potosi (Mexico)


    We report here a redesign of the CKM RICH velocity spectrometers for use in a 14GHz unseparated beam adapted to the KTeV beam line and detector hall at Fermilab (P940). The redesigns reported here comprise modest modification to the original designs for CKM(E921) to accommodate the change in beam flux, momentum, and momentum bite of the primary beam. The ultimate performance of the velocity spectrometer systems, as quantified by the missing mass squared resolution for K{sup +}->{pi}{sup +}{pi}{sup 0}, remains largely unchanged from the original design.

    Full Text Available Artificial neural networks self-organizing map type (SOM was used to classify samples of automotive gasoline C marketed in the eastern and northern regions of the state of Paraná, Brazil. The input order of parameters in the network were the values of temperature of the first drop, the 10, 50 and 90% distilled bulk, the final boiling point, density, residue content and alcohol content. A network with a topology of 25x25 and 5000 training epochs was used. The weight maps of input parameters for the trained network identified that the most important parameters for classifying samples were the temperature of the first drop and the temperature of the 10% and 50% of the distilled fuel. DOI: 

  5. A two-dose regimen of a vaccine against Escherichia coli O157:H7 type III secreted proteins reduced environmental transmission of the agent in a large-scale commercial beef feedlot clinical trial.

    Smith, David R; Moxley, Rodney A; Peterson, Robert E; Klopfenstein, Terry J; Erickson, Galen E; Clowser, Sharon L


    A clinical vaccine trial of commercially fed cattle tested the effect of a two-dose regimen of a vaccine product against type III secreted proteins of enterohemorrhagic Escherichia coli O157:H7 on the probability of detecting the organism on environmental sampling devices. Within commercial feedlots, pens of vaccinated and unvaccinated cattle were matched by reprocessing schedule and time of sampling. Vaccine was administered to all cattle within treated pens at arrival processing and again at re-implant processing. Pens of cattle were sampled 1 week after the second dose of vaccine and every 3 weeks for four test periods. Pair-matched pens of cattle were sampled concurrently. Test samples were seven ropes per pen hung overnight from the feed-bunk neck-rail (ROPES). Recovery of E. coli O157:H7 from at least one rope classified pens ROPES-positive. E. coli O157:H7 isolates were identified by standard biochemical methods and multiplex polymerase chain reaction. The probability for pens of cattle to test ROPES-positive was modeled using multilevel logistic regression with variance adjustment for clustering by matched pens and repeated measures. We studied 140 pens of cattle representing 20,556 cattle in 19 feedlots February through October 2004. Vaccinated pens of cattle were less likely to test ROPES-positive (OR = 0.59, p = 0.004). Because ROPES testing identifies organisms in the mouth of cattle, and the outcome is both associated with presence of the organism in the pen environment and correlated with the prevalence of fecal shedding, we conclude the two-dose vaccine regimen reduces the probability for environmental transmission of E. coli O157:H7 within commercial cattle feeding systems.

  6. Pathway optimization by re-design of untranslated regions for L-tyrosine production in Escherichia coli.

    Kim, Seong Cheol; Min, Byung Eun; Hwang, Hyun Gyu; Seo, Sang Woo; Jung, Gyoo Yeol


    L-tyrosine is a commercially important compound in the food, pharmaceutical, chemical, and cosmetic industries. Although several attempts have been made to improve L-tyrosine production, translation-level expression control and carbon flux rebalancing around phosphoenolpyruvate (PEP) node still remain to be achieved for optimizing the pathway. Here, we demonstrate pathway optimization by altering gene expression levels for L-tyrosine production in Escherichia coli. To optimize the L-tyrosine biosynthetic pathway, a synthetic constitutive promoter and a synthetic 5'-untranslated region (5'-UTR) were introduced for each gene of interest to allow for control at both transcription and translation levels. Carbon flux rebalancing was achieved by controlling the expression level of PEP synthetase using UTR Designer. The L-tyrosine productivity of the engineered E. coli strain was increased through pathway optimization resulting in 3.0 g/L of L-tyrosine titer, 0.0354 g L-tyrosine/h/g DCW of productivity, and 0.102 g L-tyrosine/g glucose yield. Thus, this work demonstrates that pathway optimization by 5'-UTR redesign is an effective strategy for the development of efficient L-tyrosine-producing bacteria.

  7. A cross-sectional study of the prevalence of foot lesions in post-weaning pigs and risks associated with floor type on commercial farms in England.

    Gillman, C E; KilBride, A L; Ossent, P; Green, L E


    We carried out a cross-sectional study during 2003 and 2004 to establish the prevalence and risk factors associated with floor type for commonly observed foot lesions in pigs aged 6, 8 and 14 weeks. The overall prevalence of foot lesions was 39.6% in 2283 pigs from 90 representative pig farms in England. The most prevalent lesions were heel/sole bruising (7.1%), heel/sole erosion (10.8%), heel flaps (8.4%) and toe erosion (11.6%). Pigs were kept on either solid (41%), partly slatted (28%) or fully slatted (31%) floors. Of the 104 pens with a solid floor, 26% of pens were outside with straw bedding on a soil base, 33% were indoors with deep bedding on solid concrete, 25% were partly deeply bedded on solid concrete and 16% were sparsely bedded on solid concrete. Only six of the pens with partly slatted floors were bedded. Multilevel logistic-regression models were built using data from 100 farms to examine the risks for individual foot lesions with prevalences >5%. The prevalence of toe erosions was positively associated with deep bedding, whereas deep bedding and soil floors were negatively associated with the prevalence of heel/sole erosions. Heel flaps and heel/sole bruising were both associated with slatted floors, possibly indicating a common aetiology. The greatest reduction in prevalence of all these lesions, from AFp calculations, would be achieved by moving pigs from slatted floors onto solid floors.

  8. In vitro gentamicin release from commercially available calcium-phosphate bone substitutes influence of carrier type on duration of the release profile

    Bronckers Antonius LJJ


    Full Text Available Abstract Background Polymethyl-methacrylate (PMMA beads releasing antibiotics are used extensively to treat osteomyelitis, but require surgical removal afterwards because they do not degrade. Methods As an alternative option, this report compares the in vitro gentamicin release profile from clinically used, biodegradable carrier-materials: six injectable cements and six granule-types. Cement cylinders and coated granules containing 3% gentamicin were submerged in dH2O and placed in a 48-sample parallel drug-release system. At regular intervals (30, 90, 180 min. and then every 24 h, for 21 days, the release fluid was exchanged and the gentamicin concentration was measured. The activity of released gentamicin was tested on Staphylococcus aureus. Results All combinations showed initial burst-release of active gentamicin, two cements had continuous-release (17 days. The relative release of all cements (36–85% and granules (30–62% was higher than previously reported for injectable PMMA-cements (up to 17% and comparable to other biodegradable carriers. From the cements residual gentamicin could be extracted, whereas the granules released all gentamicin that had adhered to the surface. Conclusion The high release achieved shows great promise for clinical application of these biodegradable drug-carriers. Using the appropriate combination, the required release profile (burst or sustained may be achieved.

  9. Can Job Redesign Interventions Influence a Broad Range of Employee Outcomes by Changing Multiple Job Characteristics? A Quasi-Experimental Study

    Holman, D.; Axtell, C.

  15. Orbiter Flight Deck Redesign (A Physical Layout for a Futuristic Flight Deck)

    Khorsandi, Mehrzad


    The purpose of this summer project was to develop a set of schematic drawings for redesign of the Space Shuttle flight deck from which three dimensional computer drawings can be built and viewed in a virtual environment. In order to achieve this goal, first recommendations for overall redesign of Space Shuttle previously made by experts in the field were reviewed and relevant information was extracted and delineated. Original drawings of the Space Shuttle made by Rockwell were obtained and carefully examined. In order to implement and assess any modifications in terms of space saving parameters, it was determined that the drawings alone could not achieve this objective. As a complement, physical measurements of the mockup of Space Shuttle flight deck were made and the information was categorized and properly labeled on the original drawings. Then, spacesaving redesign ideas, as motivated by expert recommendations on such things as information display panel upgrade by technologically advanced flat display units, were implemented. Next, the redesign ideas were executed on the Forward flight deck, Overhead Console, Right and Left Console, and Center Console. A new 3-D computer drawing of this was developed by modifying the existing drawing on the in-house developed software (PLAID). Finally, the drawing was transported to a Virtual Environment and observed.

  16. Digital redesign of uncertain interval systems based on time-response resemblance via particle swarm optimization.

    Hsu, Chen-Chien; Lin, Geng-Yu


    In this paper, a particle swarm optimization (PSO) based approach is proposed to derive an optimal digital controller for redesigned digital systems having an interval plant based on time-response resemblance of the closed-loop systems. Because of difficulties in obtaining time-response envelopes for interval systems, the design problem is formulated as an optimization problem of a cost function in terms of aggregated deviation between the step responses corresponding to extremal energies of the redesigned digital system and those of their continuous counterpart. A proposed evolutionary framework incorporating three PSOs is subsequently presented to minimize the cost function to derive an optimal set of parameters for the digital controller, so that step response sequences corresponding to the extremal sequence energy of the redesigned digital system suitably approximate those of their continuous counterpart under the perturbation of the uncertain plant parameters. Computer simulations have shown that redesigned digital systems incorporating the PSO-derived digital controllers have better system performance than those using conventional open-loop discretization methods.

  18. Bridging a Survey Redesign Using Multiple Imputation: An Application to the 2014 CPS ASEC

    Rothbaum Jonathan


    Full Text Available The Current Population Survey Annual Social and Economic Supplement (CPS ASEC serves as the data source for official income, poverty, and inequality statistics in the United States. In 2014, the CPS ASEC questionnaire was redesigned to improve data quality and to reduce misreporting, item nonresponse, and errors resulting from respondent fatigue. The sample was split into two groups, with nearly 70% receiving the traditional instrument and 30% receiving the redesigned instrument. Due to the relatively small redesign sample, analyses of changes in income and poverty between this and future years may lack sufficient power, especially for subgroups. The traditional sample is treated as if the responses were missing for income sources targeted by the redesign, and multiple imputation is used to generate plausible responses. A flexible imputation technique is used to place individuals into strata along two dimensions: 1 their probability of income recipiency and 2 their expected income conditional on recipiency for each income source. By matching on these two dimensions, this approach combines the ideas of propensity score matching and predictive means matching. In this article, this approach is implemented, the matching models are evaluated using diagnostics, and the results are analyzed.

  11. Redesigning a clinical mentoring program for improved outcomes in the clinical training of clerks

    Lin, Chia-Der; Lin, Blossom Yen-Ju; Lin, Cheng-Chieh; Lee, Cheng-Chun


    Introduction Mentorship has been noted as critical to medical students adapting to clinical training in the medical workplace. A lack of infrastructure in a mentoring program might deter relationship building between mentors and mentees. This study assessed the effect of a redesigned clinical mentoring program from the perspective of clerks. The objective was to assess the benefits of the redesigned program and identify potential improvements. Methods A redesigned clinical mentoring program was launched in a medical center according to previous theoretical and practical studies on clinical training workplaces, including the elements of mentor qualifications, positive and active enhancers for mentor–mentee relationship building, the timing of mentoring performance evaluation, and financial and professional incentives. A four-wave web survey was conducted, comprising one evaluation of the former mentoring program and three evaluations of the redesigned clinical mentoring program. Sixty-four fifth-year medical students in clerkships who responded to the first wave and to at least two of the three following waves were included in the study. A structured and validated questionnaire encompassing 15 items on mentor performance and the personal characteristics of the clerks was used. Mixed linear models were developed for repeated measurements and to adjust for personal characteristics. Results The results revealed that the redesigned mentoring program improved the mentors’ performance over time for most evaluated items regarding professional development and personal support provided to the mentees. Conclusions Our findings serve as an improved framework for the role of the institution and demonstrate how institutional policies, programs, and structures can shape a clinical mentoring program. We recommend the adoption of mentorship schemes for other cohorts of medical students and for different learning and training stages involved in becoming a physician. PMID

  14. FY 2000 report on the results of development of technology for commercializing high-efficiency fuel cell systems. Development of technology for commercializing high-efficiency fuel cell systems (Development of hydrogen separation type reforming technology); 2000 nendo kokoritsu nenryo denchi system jitsuyoka gijutsu kaihatsu seika hokokusho. Suiso bunrigata kaishitsu gijutsu kaihatsu



    Described herein are the FY 2000 results of development of new hydrogen production technology using natural gas as the feedstock, for promotion of commercializing high-efficiency fuel cell systems. The hydrogen separation type reforming system is composed of a reformer for producing and purifying hydrogen, and hydrogen suction unit for separating hydrogen produced. The reformer itself can produce pure hydrogen, because the hydrogen permeation membrane, provided in the reforming catalyst bed, can purify hydrogen selectively separated from the reformer gas. The remaining reformer off gas is burned with air to generate heat for the reforming reactions. This reforming process can produce as much hydrogen as does the conventional process at lower temperature, around 500 degrees C versus 800 degrees C needed by the conventional one, and hence more efficient, because hydrogen permeating through the membrane is discharged out of the system to allow the reactions to proceed without being limited by the chemical equilibrium. For development of membrane module manufacturing technology, the prototype membranes are prepared and their performances are evaluated. They are also incorporated in the test reformer to investigate the module performance and interactions between the membrane and reformer structure. Also described are improvement of efficiency of the hydrogen separation type reformer and development of the demonstration system. (NEDO)

  15. Recall of television commercials as a function of viewing context: the impact of program-commercial congruity on commercial messages.

    Sharma, A


    The effect of the congruity between the involvement types of advertising commercial and a television program on the effectiveness of the commercial was studied. Participants (N = 103) viewed either a cognitive or an affective commercial for a product, which was embedded in either a cognitive or an affective television program. The results showed that the effects of the congruence influence the impact on memory. Free recall and cued recall were significantly influenced by the program-commercial congruity. Free recall and cued recall were significantly higher for the cognitively involving commercial in the cognitively involving program context than in the affectively involving program context. Similarly, free recall and cued recall were significantly higher for the affectively involving commercial in the affectively involving program context than in the cognitively involving program context.

  18. Adjusting Strategy of Growing Commercial Distribution and Boosting Urbanization of New Type%调整商贸流通业发展战略助推新型城镇化建设



    新型城镇化建设为商贸流通业提供了新的发展机遇。当前,我国商贸流通业总体上仍处于投入推动型的粗放式的发展阶段,城乡市场分割现象依然突出;现代化的流通体系尚未真正建立起来;现代流通手段和营销方式的应用还处在起步阶段,环节较多、损耗较大、成本较高;消费环境有待净化;新兴业态质量有待提升。商贸流通业应加快调整发展战略,加强改革创新和文化建设,健全市场流通体系,推行现代化流通方式,开拓服务领域,加大民生工程建设力度,引导物流要素合理配置,重点培育城镇消费。国家应加快实施税制改革,推进金融与商贸流通业的融合发展,从而使商贸流通业有效助推新型城镇化建设。%Urbanization for new type offers exciting opportunities for commercial distribution industry. As China's commercial distribution industry remains at preliminary stage that needs investment, there is a gap between urban and rural markets. As it is in the early phase of modern distribution system, we embark on modern distribution means and marketing approaches. As a result, the commercial distribution industry is challenged by more links, huge losses, high costs, and consumption environment and new format to be improved. We should adjust development strategy, build on innovation and culture, and improve distribution system. Meanwhile we should use modern distribu-tion means, expand business scope and allocate elements of logistics factors rationally. At the same time, we should work harder to improve people's wellbeing focusing on consumption in urban areas. Central government must reform in tax regime, and keep finance and business.

  19. Commercialization of space

    Rose, James T.; Stone, Barbara A.


    Space-commercialization activities are grouped into five categories: private sector development from existing technology for private sector use; pure privatization; private sector development for U.S. government use; private sector development from novel technology for private sector use; and, finally, full commercialization. The commercialization of space categories is defined, and the key issues in each are highlighted. A description of key NASA actions is included for each category. It is concluded that NASA and other government agency involvement is a common thread across the spectrum of space commercialization activities.

  1. The Role of the IT Department in Information System and Organizational Redesign.

    Stub Petersen, Lone


    This paper is based on a qualitative study of IT organization and clinical practice over a period of 3 years supported by additional data during the last 2 years. This paper argues that redesign is central to understanding and developing both healthcare information systems and organizations. The importance of the IT organization is also stressed throughout this paper as a pertinent partner and power when considering organizational change and learning in hospitals as it can serve both as a barrier and a catalyst of change and flexibility in the organization through information systems management. Therefore it is important to consider and secure appropriate forms for redesign and learning in cooperation with the IT department.

  2. Expanding patient engagement in quality improvement and health system redesign: Three Canadian case studies.

    Baker, G Ross; Fancott, Carol; Judd, Maria; O'Connor, Patricia


    Healthcare organizations face growing pressures to increase patient-centred care and to involve patients more in organizational decisions. Yet many providers worry that such involvement requires additional time and resources and do not see patients as capable of contributing meaningfully to decisions. This article discusses three efforts in four organizations to engage patients in quality improvement efforts. McGill University Health Centre, Saskatoon Health Region, and Vancouver Coastal and Fraser Health Regions all engaged patients in quality improvement and system redesign initiatives that were successful in improving care processes, outcomes, and patient experience measures. Patient involvement in redesigning care may provide a way to demonstrate the value of patients' experiences and inputs into problem-solving, building support for their involvement in other areas. Further study of these cases and a broader survey of organizational experiences with patient involvement may help elucidate the factors that support greater patient engagement. © 2016 The Canadian College of Health Leaders.

  3. Application of cognitive engineering principles to the redesign of a dichotomous identification key for parasitology.

    Smith-Akin, Kimberly A; McLane, Sharon; Craig, Thomas M; Johnson, Todd R


    Dichotomous identification keys are used throughout biology for identification of plants, insects, and parasites. However, correct use of identification keys can be difficult as they are not usually intended for novice users who may not be familiar with the terminology used or with the morphology of the organism being identified. Therefore, we applied cognitive engineering principles to redesign a parasitology identification key for the Internet. We addressed issues of visual clutter and spatial distance by displaying a single question couplet at a time and by switching to the appropriate next couplet after the user made a choice. Our analysis of the original paper-based key versus the Web-based approach found that of 26 applicable cognitive engineering principles, the paper key did not meet 4 (15%) and partially met 11 (42%). In contrast, the redesigned key met 100% of 32 applicable cognitive engineering principles.

  9. Multi-rate digital redesign of cascaded and dynamic output feedback systems

    Xie, L. B.; Ozkul, S.; Sawant, M.; Shieh, L. S.; Tsai, J. S. H.; Tsai, C. H.


    In this paper, a new indirect digital redesign method is presented for multi-rate sampled-data control systems with cascaded and dynamic output feedback controllers. These analogue controllers are often pre-designed based on desirable frequency specifications, such as bandwidth, natural angular frequency, etc. To take advantage of the digital controller over the analogue controller, digital implementation of these analogue controllers are often desirable. As only measured input-output signals are available, an ideal state reconstructing algorithm is utilised to obtain the multi-rate discrete-time states of the original continuous-time system. Based on the Chebyshev quadrature method, the gains of the multi-rate cascaded and the output feedback digital controllers are determined from their continuous-time counterparts according to the different sampling rates employed in the different parts of the closed-loop system. As a result, the respective analogue controllers with the high-frequency and low-frequency characteristics can be implemented using the respective fast-rate sampling and slow-rate sampling digital controllers. Unlike the classical direct bilinear transform method, which is an open-loop direct digital redesign method, the proposed digital controllers take into account the state-matching of the original continuous-time closed-loop system and the digitally redesigned sampled-data closed-loop system. To further improve the state-matching performance, an improved digital redesign approach is also developed to construct the multi-rate cascaded and dynamic output feedback digital controllers. Illustrative examples are given to demonstrate the effectiveness of the developed methods.

  10. Real-time random delay compensation with prediction-based digital redesign.

    Zhang, Yongpeng; Cofie, Penrose; Ajuzie, Augustine N; Zhang, Jian; Akujuobi, Cajetan M


    Today's technological demands require challenging control solutions such as real-time applications of Networked Control System (NCS). However, due to communication protocol and shared data bus, NCS experiences uncertain and unpredictable time delays in both input and output channels. These delays cause asynchronization between the controller and the plant thereby degrading the performance of closed-loop control systems. To address this problem, this paper proposes to utilize digital redesign technique to provide real-time random delay compensation.

  12. Redesigned rotor for a highly loaded, 1800 ft/sec tip speed compressor fan stage 1: Aerodynamic and mechanical design

    Halle, J. E.; Ruschak, J. T.


    A highly loaded, high tip-speed fan rotor was designed with multiple-circular-arc airfoil sections as a replacement for a marginally successful rotor which had precompression airfoil sections. The substitution of airfoil sections was the only aerodynamic change. Structural design of the redesigned rotor blade was guided by successful experience with the original blade. Calculated stress levels and stability parameters for the redesigned rotor are within limits demonstrated in tests of the original rotor.

    Recently, many rainfall network design techniques have been developed, discussed and compared by many researchers. Present day hydrological studies require higher levels of accuracy from collected data. In numerous basins, the rain gauge stations are located without clear scientific understanding. In this study, an attempt is made to redesign rain gauge network for Johor, Malaysia in order to meet the required level of accuracy preset by rainfall data users. The existing network of 84 rain gauges in Johor is optimized and redesigned into a new locations by using rainfall, humidity, solar radiation, temperature and wind speed data collected during the monsoon season (November - February) of 1975 until 2008. This study used the combination of geostatistics method (variance-reduction method) and simulated annealing as the algorithm of optimization during the redesigned proses. The result shows that the new rain gauge location provides minimum value of estimated variance. This shows that the combination of geostatistics method (variance-reduction method) and simulated annealing is successful in the development of the new optimum rain gauge system.

  14. [Redesign of community-based health services: the solution for decreasing the quality gap].

    Wilf-Miron, Rachel; Kedem, Hagai; Heiman, Anthony; Goldman, Dorit; Shem-Tov, Orna; Kokia, Ehud


    The quality gap is defined as the gap between the observed and the expected, evidence-based, quality indicators. Experts agree that significant reduction of the quality gap requires transformation of the current system of health care provision. Maccabi Healthcare Services has formulated a "change package" in order to redesign its community-based healthcare services. This is based on a proactive approach in primary care, which manages all aspects of health for a defined community of members. This is built on multidisciplinary team-work, led by a physician and a nurse; planned visits for the management of patients with chronic diseases; one-stop-shopping for efficient health promotion; and encouraging patient-centeredness, which ensures that patient values will guide all clinical decisions and patients will be provided with support to enable self-management. The following conditions and infrastructure were required to allow for the redesign: 1) Redesign became a focus of the organizational strategy; 2) Building a comparative performance measurement for presentation at all managerial levels; 3) Agreement on the incentives to primary care clinics, which voluntarily joined the process of change; training of "quality leaders" who will use common terms and methodology to improve the quality of care. Starting in 2005 as a "pilot project", the change process has gradually evolved to include about 50 primary care clinics towards the end of the year 2007.

  15. Checklists Application Accessibility and Usability for Redesign of Site Accessible for the Elderly users

    Anne Lesinhovski


    Full Text Available This paper presents the evaluation of the accessibility and usability of four sites with information and services for the elderly user.

  16. Biomechanical evaluation of supermarket cashiers before and after a redesign of the checkout counter.

    Draicchio, Francesco; Trebbi, Martina; Mari, Silvia; Forzano, Federico; Serrao, Mariano; Sicklinger, Andreas; Silvetti, Alessio; Iavicoli, Sergio; Ranavolo, Alberto


    An experiment was carried out on supermarket cashiers to evaluate the time, kinematic and electromyographic changes, in both sitting and standing positions, following the redesign of a checkout counter. The novelty of the prototype checkout counter is a disk wheel placed in the bagging area, which is designed to avoid the cashier having to manually push products along the bagging area. The kinematic evaluation was based on the upper limb and trunk range of motions (RoM). The electromyographic parameters assessed were mean and maximum muscular activations. Three factors were taken into account: design (before and after redesign), posture (standing or sitting) and bagging area (anterior or posterior). The results show that the RoM values are lowest after the intervention and in the standing position. Mean and maximum muscular activation patterns are similar. Differences related to the bagging area in which the goods were released also emerged. The disk wheel represents a valid aid for reducing biomechanical overload in cashiers; the standing position is biomechanically more advantageous. Practitioner Summary: EMG and optoelectronic motion analysis systems are useful for the quantitative assessment of the effects of the redesign of the workplace biomechanical risk. Our results suggest that a disk wheel positioned in the bagging area reduces the biomechanical risk for cashiers and increases time spent resting.

  18. Recycling sound in Commercials

    Charlotte Rørdam Larsen


    Full Text Available Commercials offer the opportunity for intergenerational memory and impinge on cultural memory. TV commercials for foodstuffs often make reference to past times as a way of authenticating products. This is frequently achieved using visual cues, but in this paper I would like to demonstrate how such references to the past and ‘the good old days’ can be achieved through sounds. In particular, I will look at commercials for Danish non-dairy spreads, especially for OMA margarine. These commercials are notable in that they contain a melody and a slogan – ‘Say the name: OMA margarine’ – that have basically remained the same for 70 years. Together these identifiers make OMA an interesting Danish case to study. With reference to Ann Rigney’s memorial practices or mechanisms, the study aims to demonstrate how the auditory aspects of Danish margarine commercials for frying tend to be limited in variety: in general, the soundtracks of margarine commercials seem to merge into one, they are somewhat alike. The OMA commercials are no exception, but the OMA melody makes a distinction. In general the soundtracks of OMA margarine commercials (and the use of melody seem to have shifted from using a predominantly semantic causal soundtrack to tracks using aesthetic and musicalised elements which are supposed to arouse more sensuous feelings in the consumers.

  1. LOLAS-2 : redesign of an optical turbulence profiler

    Avila, R; Tapia-Rodriguez, J J; Sanchez, L J; Cruz-Gonzalez, I; Aviles, J L; Valdes-Hernandez, O; Carrasco, E


    We present the development, tests and first results of the second generation Low Layer Scidar (LOLAS-2). This instrument constitutes a strongly improved version of the prototype Low Layer Scidar, which is aimed at the measurement of optical turbulence profiles close to the ground, with high altitude-resolution. The method is based on the Generalised Scidar principle which consists in taking double-star scintillation images on a defocused pupil plane and calculating in real time the autocovariance of the scintillation. The main components are an open-truss 40-cm Ritchey-Chr\\'etien telescope, a german-type equatorial mount, an Electron Multiplying CCD camera and a dedicated acquisition and real-time data processing software. The new optical design of LOLAS-2 is significantly simplified compared with the prototype. The experiments carried out to test the permanence of the image within the useful zone of the detector and the stability of the telescope focus show that LOLAS-2 can function without the use of the au...




    Full Text Available This study presents a novel model for assignment of internal auditors to branches of businesses. Previous studies have concerned with minimizing the cost but in this model, aim is maximizing auditor’s utility. For this purpose an integer programming model introduced. The objective is maximizing the auditors’ total utility. Each branch has different impact values for auditors, which indicate auditors’ utility level in terms of location, size and type of branches. Also to keep the balance of auditor’s working days and total gained impact values particular constraints are defined for the integer programming model. This implementation has 3 particular steps; first is quantification of the branches’ effects on the auditors. AHP method is used to define branches’ impact values. The second is simulating the durations of auditing process. To minimize the effect of abnormal situations, durations are simulated. Last step is to reach the rotation of auditors, total working days and the total utility of the auditor; the integer programming model is solved by Python-Gurobi Optimizer.

  4. Redesigning the substrate specificity of an enzyme: isocitrate dehydrogenase.

    Doyle, S A; Fung, S Y; Koshland, D E


    Despite the structural similarities between isocitrate and isopropylmalate, isocitrate dehydrogenase (IDH) exhibits a strong preference for its natural substrate. Using a combination of rational and random mutagenesis, we have engineered IDH to use isopropylmalate as a substrate. Rationally designed mutations were based on comparison of IDH to a similar enzyme, isopropylmalate dehydrogenase (IPMDH). A chimeric enzyme that replaced an active site loop-helix motif with IPMDH sequences exhibited no activity toward isopropylmalate, and site-directed mutants that replaced IDH residues with their IPMDH equivalents only showed small improvements in k(cat). Random mutants targeted the IDH active site at positions 113 (substituted with glutamate), 115, and 116 (both randomized) and were screened for activity toward isopropylmalate. Six mutants were identified that exhibited up to an 8-fold improvement in k(cat) and increased the apparent binding affinity by as much as a factor of 80. In addition to the S113E mutation, five other mutants contained substitutions at positions 115 and/or 116. Most small hydrophobic substitutions at position 116 improved activity, possibly by generating space to accommodate the isopropyl group of isopropylmalate; however, substitution with serine yielded the most improvement in k(cat). Only two substitutions were identified at position 115, which suggests a more specific role for the wild-type asparagine residue in the utilization of isopropylmalate. Since interactions between neighboring residues in this region greatly influenced the effects of each other in unexpected ways, structural solutions were best identified in combinations, as allowed by random mutagenesis.

  5. Marketing mix - commercial gas

    Ford, M.F.


    British Gas Corp. points out that a substantial increase in the use of gas in Great Britain's commercial energy market has occurred in the past 6 yr. Some of the newest applications of gas are in the areas of the cook/freeze system of preparing frozen foods in commercial catering, commissariats preparing in-flight food, and heating/cooling systems of large buildings. The variety of buildings and institutions using gas-fired systems indicates that, with the sensible pricing policies and the security of an indigenous fuel, the commercial market for gas will continue to develop for several years in Britain.

  10. Task design, psycho-social work climate and upper extremity pain disorders--effects of an organisational redesign on manual repetitive assembly jobs.

    Christmansson, M; Fridén, J; Sollerman, C


    A company redesign was carried out to improve production efficiency and minimise the prevalence of work-related musculoskeletal disorders and sick leave. The redesign was evaluated on the basis of studies of assembly workers before (17 workers) and after (12 workers) the redesign. The redesign resulted in more varied, less repetitive, and more autonomous assembly jobs. The psycho-social work climate was both improved and impaired. A medical examination showed that eight of 17 workers before and nine of 12 workers after the redesign suffered from upper extremity pain disorders. Neither the production goals nor the goals of the redesign were fulfilled. Our conclusion was that the increased task variation and impaired psycho-social work climate, combined with a lack of skill and competence, actually increased the physical stress, risk for disorders and difficulties in fulfilling the production goals.

  11. Can job redesign interventions influence a broad range of employee outcomes by changing multiple job characteristics? A quasi-experimental study.

    Holman, David; Axtell, Carolyn


    Many job redesign interventions are based on a multiple mediator-multiple outcome model in which the job redesign intervention indirectly influences a broad range of employee outcomes by changing multiple job characteristics. As this model remains untested, the aim of this study is to test a multiple mediator-multiple outcome model of job redesign. Multilevel analysis of data from a quasi-experimental job redesign intervention in a call center confirmed the hypothesized model and showed that the job redesign intervention affected a broad range of employee outcomes (i.e., employee well-being, psychological contract fulfillment, and supervisor-rated job performance) through changes in 2 job characteristics (i.e., job control and feedback). The results provide further evidence for the efficacy and mechanisms of job redesign interventions. (PsycINFO Database Record

  15. Redesign of a conformal boundary recovery algorithm for 3D Delaunay triangulation

    CHEN Jian-jun; ZHENG Yao


    Boundary recovery is one of the main obstacles in applying the Delaunay criterion to mesh generation. A standard resolution is to add Steiner points directly at the intersection positions between missing boundaries and triangulations. We redesign the algorithm with the aid of some new concepts, data structures and operations, which make its implementation routine.Furthermore, all possible intersection cases and their solutions are presented, some of which are seldom discussed in the literature. Finally, numerical results are presented to evaluate the performance of the new algorithm.

  16. Integrating biological redesign: where synthetic biology came from and where it needs to go.

    Way, Jeffrey C; Collins, James J; Keasling, Jay D; Silver, Pamela A


    Synthetic biology seeks to extend approaches from engineering and computation to redesign of biology, with goals such as generating new chemicals, improving human health, and addressing environmental issues. Early on, several guiding principles of synthetic biology were articulated, including design according to specification, separation of design from fabrication, use of standardized biological parts and organisms, and abstraction. We review the utility of these principles over the past decade in light of the field's accomplishments in building complex systems based on microbial transcription and metabolism and describe the progress in mammalian cell engineering.

  17. Leadership experiences in the community for nursing students. Redesigning education for the 21st century.

    Mellon, S; Nelson, P


    To respond to massive changes in health care delivery, nursing curriculum redesign requires that we return to our roots in the community and the visionary leadership of Lillian Wald, whose Henry Street Settlement (1,2) remains a model for community-based leadership. Wald's mission--to serve those in need, wherever they may be found--remains our legacy. But while the challenge of preparing students to function within a multitude of settings is not new, the changes now confronting faculty, students, and the entire health care system are taking place at a startling pace.

  19. Commercial Conspiracy Theories

    Adrian eFurnham


    Full Text Available There are many ways to categorise conspiracy theories. In the present study, we examined individual and demographic predictors of beliefs in commercial conspiracy theories among a British sample of over 300 women and men. Results showed people were cynical and sceptical with regard to advertising tricks, as well as the tactics of organisations like banks and alcohol, drug and tobacco companies. Beliefs sorted into four identifiable clusters, labelled sneakiness, manipulative, change-the-rules and suppression/prevention. The high alpha for the overall scale suggested general beliefs in commercial conspiracy. Regressions suggested that those people who were less religious, more left-wing, more pessimistic, less (self-defined as wealthy, less Neurotic and less Open-to-Experience believed there was more commercial conspiracy. Overall the individual difference variables explained relatively little of the variance in these beliefs.The implications of these findings for the literature on conspiracy theories are discussed.

  20. Commercialization of NESSUS: Status

    Thacker, Ben H.; Millwater, Harry R.


    A plan was initiated in 1988 to commercialize the Numerical Evaluation of Stochastic Structures Under Stress (NESSUS) probabilistic structural analysis software. The goal of the on-going commercialization effort is to begin the transfer of Probabilistic Structural Analysis Method (PSAM) developed technology into industry and to develop additional funding resources in the general area of structural reliability. The commercialization effort is summarized. The SwRI NESSUS Software System is a general purpose probabilistic finite element computer program using state of the art methods for predicting stochastic structural response due to random loads, material properties, part geometry, and boundary conditions. NESSUS can be used to assess structural reliability, to compute probability of failure, to rank the input random variables by importance, and to provide a more cost effective design than traditional methods. The goal is to develop a general probabilistic structural analysis methodology to assist in the certification of critical components in the next generation Space Shuttle Main Engine.

  2. Commercialization of biobanks.

    Evers, Kathinka; Forsberg, Joanna; Hansson, Mats


    Biobank policy and regulations profoundly vary between different societies. One area with profound differences in culture and tradition concerns commercialization, and the possibility of using the human body as a capital resource. In the United States there is acceptance of this possibility, whereas European law is based on principles that categorically prohibit selling parts of the human body. We suggest that questions of commercialization in the area of biobanking must be considered in relation to different ethical values, notably the principle of best possible use of collected biobank materials for the benefit of vital patient interests.

    Full Text Available In Zimbabwe two types of barns are commonly used for tobacco curing, namely the traditional and Rocket barns. The traditional barn and the Rocket Barn loose 98.5% and 55.6% of the energy supplied respectively. The latter is 43.6% more thermally efficient than the traditional barn. There is, however, potential of increasing the energy efficiency of both barns. In this study, a design that incorporates structural changes to reduce heat loss as well as recovery of heat was developed. The design is a combination of commercially available components, and allows for ventilation heat re-use and increased heat transfer from furnace ducts to the drying chamber. The structure was found to be 54.7% more thermally efficient than the Rocket barn and 74.2% more efficient than the traditional barn. The new design needs to be field-tested so that it can be adopted by tobacco farmers.

  6. A University Web Portal redesign applying accessibility patterns. Breaking Down Barriers for Visually Impaired Users

    Hernán Sosa


    Full Text Available Definitely, the WWW and ICTs have become the preferred media for the interaction between society and its citizens, and public and private organizations have today the possibility of deploying their activities through the Web. In particular, university education is a domain where the benefits of these technological resources can strongly contribute in caring for students. However, most university Web portals are inaccessible to their user community (students, professors, and non-teaching staff, between others, since these portals do not take into account the needs of people with different capabilities. In this work, we propose an accessibility pattern driven process to the redesign of university Web portals, aiming to break down barriers for visually impaired users. The approach is implemented to a real case study: the Web portal of Universidad Nacional de la Patagonia Austral (UNPA. The results come from applying accessibility recommendations and evaluation tools (automatic and manual from internationally recognized organizations, to both versions of the Web portal: the original and the redesign one.

  7. Application of high-turning bowed compressor stator to redesign of highly loaded fan stage

    Shaobin LI; Jiexian SU; Zhongqi WANG


    A redesign of a highly loaded fan stage by using high-turning bowed compressor stator was conducted. The original tandem stator was replaced by the highly loaded bowed stator which was applicable to highly sub-sonic flow conditions. 3D contouring technique and local modification of blade were applied to the design of the bowed blade in order to improve the aerodynamic per-formance and the matching of the rotor and stator blade rows. Performance curves at different rotating speeds and performances at different operating points for both the original fan stage and redesigned fan stage were obtained by numerical simulations. The results show that the highly loaded bowed stator can be used not only to improve the structure and the aerodynamic performances at various operating points of the compressor stage but also to pro-vide high performances at off-design conditions. It is believed that the highly loaded bowed stator can advance the design of high-performance compressor.

  8. Redesigning a Ministry of Health's organizational structure: exploring implementation challenges through Botswana's experiences.

    Seitio-Kgokgwe, Onalenna; Gauld, Robin D C; Hill, Philip C; Barnett, Pauline


    The Botswana's Ministry of Health redesigned and adopted a new organizational structure in 2005, which was poorly implemented. This article explores factors that influenced the implementation of this organizational structure. This article draws from data collected through in-depth interviews with 54 purposively selected key informants comprising policy makers, senior managers and staff of the Ministry of Health (N = 40) and senior officers from various stakeholder organizations (N = 14). Participants generally felt that the review of the Ministry of Health organizational structure was important. The previous structure was considered obsolete with fragmented functions that limited the overall performance of the health system. The new organizational structure was viewed to be aligned to current national priorities with potential to positively influence performance. Some key weaknesses identified included lack of consultation and information sharing with workers during the restructuring process, which affected the understanding of their new roles, failure to mobilize key resources to support implementation of the new structure and inadequate monitoring of the implementation process. Redesigning an organizational structure is a major change. There is a need for effective and sustained leadership to plan, direct, coordinate, monitor and evaluate the implementation phase of the reform. Copyright © 2014 John Wiley & Sons, Ltd.

  10. Design and Redesign of a Multimodal Classroom Task – Implications for Teaching and Learning

    Anne Öman


    This paper presents a case study of technology-mediated instruction at the primary-school level including an analysis of the designed task and how the teacher orchestrated the digital resources during three introductory classes. The aim was also to explore the pupils’ redesigning of advertising films based on teacher’s instructions and available digital resources. Sequences of a learning trajectory were video recorded and analysed from a multimodal perspective with a focus on the designed task and the processes of how pupils orchestrate meaning through their selection and configuration of available designs. The findings show a distinction between the selection of design elements in the teacher’s orchestration of the laptop resources during instruction and the pupils’ redesigning of the task. Pupils’ work developed from the linguistic design provided by the teacher towards visual design and the use of images as the central mode of expression in the process of creating advertising films. The findings also indicate a lack of orientation towards subject content due to the teacher’s primary focus on introducing the software.

  11. An evaluation of the National Curriculum Redesign Project: Eighth grade science curriculum pedagogical strategies

    Chalwell-Brewley, Lavon P.

    The purpose of this study was to examine the effectiveness of the eighth grade science National Curriculum Redesign Project. The site for this study was an urban secondary school in the British Virgin Islands. The school's population consisted of 1600 students and 120 teachers, where approximately 70% of the students were from low socioeconomic families (Secondary High School Statistical Records, 2006). The school's population was tri-cultural and consisted of approximately more Black West Indian, than Hispanic and Caucasian students and teachers. The school employed a student centered and pedagogical approach. The classroom's structure comprised of heterogeneously grouped inclusion classes with class sizes ranging between 27--40 students. The results of several studies revealed that the school's graduates did not have vital skills to work and effectively function in the work place (Organization of Eastern Caribbean States, 2000). These findings challenged the curriculum attributes and the school's pedagogical practices as it relates to providing powerful discourse in good instruction and improved academic achievement skills. Thus, the National Curriculum Redesign Project was developed to ensure teaching-learning components work together to foster significant learning practices. The review of the literature informed and substantiated the research and the related research questions. The population sample consisted of three secondary school science teachers and 26 students. Questionnaires and interview data collecting tools were employed. The data was analyzed to identify patterns and themes in responses. Descriptive statistics consisting of frequencies and percentage were used to support qualitative information and recommendations were made.

  12. Digital redesign of the control system for the Robotics Research Corporation model K-1607 robot

    Carroll, Robert L.


    The analog control system for positioning each link of the Robotics Research Corporation Model K-1607 robot manipulator was redesigned for computer control. In order to accomplish the redesign, a linearized model of the dynamic behavior of the robot was developed. The parameters of the model were determined by examination of the input-output data collected in closed-loop operation of the analog control system. The robot manipulator possesses seven degrees of freedom in its motion. The analog control system installed by the manufacturer of the robot attempts to control the positioning of each link without feedback from other links. Constraints on the design of a digital control system include: the robot cannot be disassembled for measurement of parameters; the digital control system must not include filtering operations if possible, because of lack of computer capability; and criteria of goodness of control system performing is lacking. The resulting design employs sampled-data position and velocity feedback. The criteria of the design permits the control system gain margin and phase margin, measured at the same frequencies, to be the same as that provided by the analog control system.

  13. Computational fluid dynamics simulation and redesign of a screw conveyor reactor.

    Wan, Yinkun; Hanley, Thomas R


    National Renewable Energy Laboratory (NREL) designed a shrinking-bed reactor to maintain a constant bulk packing density of cellulosic biomass. The high solid-to-liquid ratio in the pretreatment process allows a high sugar yield and avoids the need to flush large volumes of solution through the reactor. To scale up the shrinking-bed reactor, NREL investigated a pilot-scale screw conveyor reactor in which an interrupted flight between screws was employed to mimic the "shrinking-bed" effect. In the experiments with the screw conveyor reactor, overmixing and uneven flow occurred. These phenomena produce negative effects on biomass hydrolysis. The flow behavior inside the reactor was analyzed to allow redesign of the screw to achieve adequate mixing and even flow. In the present study, computational fluid dynamics (CFD) was utilized to simulate the fluid flow in the porous media, and a new screw design was proposed. CFD analysis performed on the redesigned reactor indicated that an even flow pattern was achieved.

  14. Redesign and Automation of a mold for manufacturing of refrigerated display cases using Polyurethane Foam Injection

    Eugenio Yime


    Full Text Available Context: To stay competitive over time, a company must continually submit their processes to improvements and updates. Herein are proposed some improvements with regard to safety at work and the reduction of time that occurs during the operation of a mold for manufacturing refrigerators. Method: Some operating conditions of the mold are analyzed and then some factors affecting the processing time and the safety of operating personnel are established. The weaknesses found are related to the intrinsic design of the mold, which raises the need for a structural redesign that also includes automation. Results: It is presented a new design and way to operate the mold which reduces the risk of accidents at having no heavy loads over operator heads. Another contribution of the redesign is the increase in the system rigidity which helps to reduce manufacturing defects. Finally, it is show a automation design which helps to reduce manufacturing times. Conclusions: Significant improvements were obtained in the operation of the mold, such as the reduction of occupational hazards and reduced manufacturing time of refrigerators. These improvements translate into benefits for the company, by reducing costs and increasing production. Both benefits help strengthen the competitiveness of the company.

  15. Innovation in ambulatory care: a collaborative approach to redesigning the health care workplace.

    Johnson, Paula A; Bookman, Ann; Bailyn, Lotte; Harrington, Mona; Orton, Piper


    To improve the quality of patient care and work satisfaction of the physicians and staff at an ambulatory practice that had recently started an innovative model of clinical care for women. The authors used an inclusive process, collaborative interactive action research, to engage all physicians and staff members in assessing and redesigning their work environment. Based on key barriers to working effectively and integrating work and family identified in that process, a pilot project with new work practices and structures was developed, implemented, and evaluated. The work redesign process established cross-occupational care teams in specific clinical areas. Members of the teams built skills in assessing clinical operations in their practice areas, developed new levels of collaboration, and constructed new models of distributed leadership. The majority of participants reported an improvement in how their area functioned. Integrating work and family/personal life-particularly practices around flexible work arrangements-became an issue for team discussion and solutions, not a matter of individual accommodation by managers. By engaging the workforce, collaborative interactive action research can help achieve lasting change in the health care workplace and increase physicians' and staff members' work satisfaction. This "dual agenda" may be best achieved through a collaborative process where cross-occupational teams are responsible for workflow and outcomes and where the needs of patients and providers are integrated.

    Saleem Jason J


    Full Text Available Abstract Background Based on barriers to the use of computerized clinical decision support (CDS learned in an earlier field study, we prototyped design enhancements to the Veterans Health Administration's (VHA's colorectal cancer (CRC screening clinical reminder to compare against the VHA's current CRC reminder. Methods In a controlled simulation experiment, 12 primary care providers (PCPs used prototypes of the current and redesigned CRC screening reminder in a within-subject comparison. Quantitative measurements were based on a usability survey, workload assessment instrument, and workflow integration survey. We also collected qualitative data on both designs. Results Design enhancements to the VHA's existing CRC screening clinical reminder positively impacted aspects of usability and workflow integration but not workload. The qualitative analysis revealed broad support across participants for the design enhancements with specific suggestions for improving the reminder further. Conclusions This study demonstrates the value of a human-computer interaction evaluation in informing the redesign of information tools to foster uptake, integration into workflow, and use in clinical practice.

  17. Evaluation and redesign of manual material handling in a vaccine production centre's warehouse.

    Torres, Yaniel; Viña, Silvio


    This study was conducted in a warehouse at a vaccine production centre where improvement to existing storage and working conditions were sought through the construction of a new refrigerated store section (2-8C°). Warehousing tasks were videotaped and ergonomics analysis tools were used to assess the risk of developing MSDs. Specifically, these tools were the Rapid Entire Body Assessment (REBA) and the NIOSH equation. The current plant layout was sketched and analyzed to find possible targets for improvement trough the application of general work space design and ergonomics principles. Seven of the eight postures evaluated with REBA had a total score between 8 and 10, meaning a high risk, and only one was at a medium risk level. Nine of the eleven manual material handling tasks analyzed with the NIOSH equation had a Lifting Index between 1.14 and 1.80 and two had a recommended weight limit of 0 kg, indicating a need for job redesign. Solutions included the redesign of shelves, the design of a two-step stair and a trolley with adjustable height; also, changes in work methods were proposed by introducing a two-workers lifting strategy and job rotation, and, finally, a restructuring of plant layout was completed.

  19. Redesigned Surface Based Machining Strategy and Method in Peripheral Milling of Thin-walled Parts

    JIA Zhenyuan; GUO Qiang; SUN Yuwen; GUO Dongming


    Currently, simultaneously ensuring the machining accuracy and efficiency of thin-walled structures especially high performance parts still remains a challenge. Existing compensating methods are mainly focusing on 3-aixs machining, which sometimes only take one given point as the compensative point at each given cutter location. This paper presents a redesigned surface based machining strategy for peripheral milling of thin-walled parts. Based on an improved cutting force/heat model and finite element method(FEM) simulation environment, a deflection error prediction model, which takes sequence of cutter contact lines as compensation targets, is established. And an iterative algorithm is presented to determine feasible cutter axis positions. The final redesigned surface is subsequently generated by skinning all discrete cutter axis vectors after compensating by using the proposed algorithm. The proposed machining strategy incorporates the thermo-mechanical coupled effect in deflection prediction, and is also validated with flank milling experiment by using five-axis machine tool. At the same time, the deformation error is detected by using three-coordinate measuring machine. Error prediction values and experimental results indicate that they have a good consistency and the proposed approach is able to significantly reduce the dimension error under the same machining conditions compared with conventional methods. The proposed machining strategy has potential in high-efficiency precision machining of thin-walled parts.

  20. Employee health benefit redesign at the academic health center: a case study.

    Marshall, Julie; Weaver, Deirdre C; Splaine, Kevin; Hefner, David S; Kirch, Darrell G; Paz, Harold L


    The rapidly escalating cost of health care, including the cost of providing health care benefits, is a significant concern for many employers. In this article, the authors examine a case study of an academic health center that undertook a complete redesign of its health benefit structure to control rising costs, encourage use of its own provider network, and support employee wellness. With the implementation in 2006 of a high-deductible health plan combined with health reimbursement arrangements and wellness incentives, the Penn State Hershey Medical Center (PSHMC) was able to realize significant cost savings and increase use of its own network while maintaining a high level of employee satisfaction. By contracting with a single third-party administrator for its self-insured plan, PSHMC reduced its administrative costs and simplified benefit choices for employees. In addition, indexing employee costs to salary ensured that this change was equitable for all employees, and the shift to a consumer-driven health plan led to greater employee awareness of health care costs. The new health benefit plan's strong focus on employee wellness and preventive health has led to significant increases in the use of preventive health services, including health risk assessments, cancer screenings, and flu shots. PSHMC's experience demonstrates the importance of clear and ongoing communication with employees throughout--before, during, and even after--the process of health benefit redesign.

  11. Lunar Commercial Mining Logistics

    Kistler, Walter P.; Citron, Bob; Taylor, Thomas C.


    Innovative commercial logistics is required for supporting lunar resource recovery operations and assisting larger consortiums in lunar mining, base operations, camp consumables and the future commercial sales of propellant over the next 50 years. To assist in lowering overall development costs, ``reuse'' innovation is suggested in reusing modified LTS in-space hardware for use on the moon's surface, developing product lines for recovered gases, regolith construction materials, surface logistics services, and other services as they evolve, (Kistler, Citron and Taylor, 2005) Surface logistics architecture is designed to have sustainable growth over 50 years, financed by private sector partners and capable of cargo transportation in both directions in support of lunar development and resource recovery development. The author's perspective on the importance of logistics is based on five years experience at remote sites on Earth, where remote base supply chain logistics didn't always work, (Taylor, 1975a). The planning and control of the flow of goods and materials to and from the moon's surface may be the most complicated logistics challenges yet to be attempted. Affordability is tied to the innovation and ingenuity used to keep the transportation and surface operations costs as low as practical. Eleven innovations are proposed and discussed by an entrepreneurial commercial space startup team that has had success in introducing commercial space innovation and reducing the cost of space operations in the past. This logistics architecture offers NASA and other exploring nations a commercial alternative for non-essential cargo. Five transportation technologies and eleven surface innovations create the logistics transportation system discussed.

  12. Redesign of the CKM RICH velocity spectrometers for use in a 1/4 GHz unseparated beam

    Cooper, Peter S.; /Fermilab; Engelfried, Jurgen; /San Luis Potosi U.


    I report here a redesign of the CKM RICH velocity spectrometers for use in a 1/4 GHz unseparated beam adapted to the KTeV beam line and detector hall at Fermilab (P940). The redesigns reported here comprise modest modification to the original designs for CKM(E921) to accommodate the change in beam flux, momentum, and momentum bite of the primary beam. The ultimate performance of the velocity spectrometer systems, as quantified by the missing mass squared resolution for K{sup +} {yields} {pi}{sup +} x{sup 0}, remains largely unchanged from the original design.

  13. The frequency and distance of movements of pigs and semen between commercial and non-commercial piggeries in New Zealand.

    Neumann, E J; Pearson, A B; Sanson, R I; Nicoll, K J; Clement, F I


    The study was conducted to identify movement patterns of disease conveyors in the New Zealand pig industry. The principal objective of the study was to identify data relating to the frequency and distance of movements of pigs and semen amongst pig holdings. A secondary objective of the study was to generate criteria suitable for categorisation of different pig breeding or raising operations. Prospective data were collected by a census of all known pig holdings in New Zealand using a mailed-out questionnaire. The survey yielded 1,477 responses (114 commercial and 1,363 non-commercial pig holdings) for descriptive analysis. Seven farm-types were created to describe typical pig holdings and were based on pig herd inventory, herd type, and participation in the movement of pigs or semen: Commercial genetic supplier, commercial feeder, commercial weaner producer, para-commercial genetic supplier, para-commercial feeder, para-commercial weaner producer, and non-commercial herd. The farm-type with the highest frequency of movements off the piggery was the para-commercial genetic suppliers with a median of 5.3 movements off per month. Commercial feeders had the second highest off farm movement with a median of 4.6 movements per month; these primarily represented movements to an abattoir. The highest frequencies of movements on to a piggery were experienced by commercial genetic suppliers (3.5 per month) and were due to the delivery of semen or replacement gilt/boars. Para-commercial and non-commercial farm-types reported less frequent movement activities both onto and off the piggery compared to their commercial counterparts. Most movements of pigs and semen occurred over distances of less than 100 km. The study showed that New Zealand has a relatively small but widely dispersed commercial pig industry with a large number of non-commercial pig holdings and there was a substantial geographic overlap between these industry sectors. Knowledge of the frequency of movements of

  16. A systematic review of human factors and ergonomics (HFE)-based healthcare system redesign for quality of care and patient safety.

    Xie, Anping; Carayon, Pascale


    Healthcare systems need to be redesigned to provide care that is safe, effective and efficient, and meets the multiple needs of patients. This systematic review examines how human factors and ergonomics (HFE) is applied to redesign healthcare work systems and processes and improve quality and safety of care. We identified 12 projects representing 23 studies and addressing different physical, cognitive and organisational HFE issues in a variety of healthcare systems and care settings. Some evidence exists for the effectiveness of HFE-based healthcare system redesign in improving process and outcome measures of quality and safety of care. We assessed risk of bias in 16 studies reporting the impact of HFE-based healthcare system redesign and found varying quality across studies. Future research should further assess the impact of HFE on quality and safety of care, and clearly define the mechanisms by which HFE-based system redesign can improve quality and safety of care.

  17. Commercialization of microfluidic devices.

    Volpatti, Lisa R; Yetisen, Ali K


    Microfluidic devices offer automation and high-throughput screening, and operate at low volumes of consumables. Although microfluidics has the potential to reduce turnaround times and costs for analytical devices, particularly in medical, veterinary, and environmental sciences, this enabling technology has had limited diffusion into consumer products. This article analyzes the microfluidics market, identifies issues, and highlights successful commercialization strategies. Addressing niche markets and establishing compatibility with existing workflows will accelerate market penetration. Copyright © 2014 Elsevier Ltd. All rights reserved.

  1. Commercialization Effort for 1W Consumer Electronics Power Pack

    Carlstrom, Charles, M.


    A commercial ready fuel cell charger has been further developed, demonstrated, and field tested during the three phases of this project. The work performed and demonstrated has shown the commercialization readiness of this future product and underlying technology. The tasks in phase 1 of the project focused on component cost reduction, redesign for manufacturability, performance & reliability testing, and system integration. The end of phase 1 was completed on time and was signified by passing the Go/No-Go checkpoint. As shown in the report all technical metrics have been met or exceeded and the Go/No-Go checkpoint was passed in November of 2009. The tasks in phase 2 focused on tool fabrication and tooled component prove-out in working systems. The end of Phase 2 was the accomplishment of building working systems made almost completely of tooled components. The tasks in phase 3 of the project were preparing for and executing a 75 unit field test of the DMFC charger product developed in Phase 1 and phase 2. This field test demonstrated the functionality of the DMFC in the hands of real users while also providing feedback for potential design improvements. This was the first time a significant number of MTI units were put into the field to test usability and functionality. Feedback from the field test was positive and the units functioned well in the field.

  2. Aerogel commercialization pilot project. Final program report



    Aerogels are extremely light weight, high surface area, very insulative materials that offer many potential improvements to commercial products. Aerogels have been the subject of extensive research at Department of Energy Laboratories and have been considered one of the technology most ready for commercialization. However, commercialization of the technology had been difficult for the National Laboratories since end users were not interested in the high temperature and high pressure chemical processes involved in manufacturing the raw material. Whereas, Aerojet as a supplier of rocket fuels, specialty chemicals and materials had the manufacturing facilities and experience to commercially produce aerogel-type products. Hence the TRP provided a link between the technology source (National Laboratories), the manufacturing (Aerojet) and the potential end users (other TRP partners). The program successfully produced approximately 500 ft{sup 2} of organic aerogel but failed to make significant quantities of silica aerogel. It is significant that this production represents both the largest volume and biggest pieces of organic aerogel ever produced. Aerogels, available from this program, when tested in several prototype commercial products were expected to improve the products performance, but higher than expected projected production costs for large scale manufacture of aerogels has limited continued commercial interest from these partners. Aerogels do, however, offer potential as a specialty material for some high value technology and defense products.

  12. Applying the Context, Input, Process, Product Evaluation Model for Evaluation, Research, and Redesign of an Online Master’s Program

    Hatice Sancar Tokmak


    Full Text Available This study aimed to evaluate and redesign an online master’s degree program consisting of 12 courses from the informatics field using a context, input, process, product (CIPP evaluation model. Research conducted during the redesign of the online program followed a mixed methodology in which data was collected through a CIPP survey, focus-group interview, and open-ended questionnaire. An initial CIPP survey sent to students, which had a response rate of approximately 60%, indicated that the Fuzzy Logic course did not fully meet the needs of students. Based on these findings, the program managers decided to improve this course, and a focus group was organized with the students of the Fuzzy Logic course in order to obtain more information to help in redesigning the course. Accordingly, the course was redesigned to include more examples and visuals, including videos; student-instructor interaction was increased through face-to-face meetings; and extra meetings were arranged before exams so that additional examples could be presented for problem-solving to satisfy students about assessment procedures. Lastly, the modifications to the Fuzzy Logic course were implemented, and the students in the course were sent an open-ended form asking them what they thought about the modifications. The results indicated that most students were pleased with the new version of the course.

  15. Exploring Demand Charge Savings from Commercial Solar

    Darghouth, Naim [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Barbose, Galen [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Mills, Andrew [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Wiser, Ryan [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Gagnon, Pieter [National Renewable Energy Lab. (NREL), Golden, CO (United States); Bird, Lori [National Renewable Energy Lab. (NREL), Golden, CO (United States)


    Commercial retail electricity rates commonly include a demand charge component, based on some measure of the customer’s peak demand. Customer-sited solar PV can potentially reduce demand charges, but the magnitude of these savings can be difficult to predict, given variations in demand charge designs, customer loads, and PV generation profiles. Moreover, depending on the circumstances, demand charges from solar may or may not align well with associated utility cost savings. Lawrence Berkeley National Laboratory (Berkeley Lab) and the National Renewable Energy Laboratory (NREL) are collaborating in a series of studies to understand how solar PV can reduce demand charge levels for a variety of customer types and demand charges designs. Previous work focused on residential customs with solar. This study, instead, focuses on commercial customers and seeks to understand the extent and conditions under which rooftop can solar reduce commercial demand charges. To answer these questions, we simulate demand charge savings for a broad range of commercial customer types, demand charge designs, locations, and PV system characteristics. This particular analysis does not include storage, but a subsequent analysis in this series will evaluate demand charge savings for commercial customers with solar and storage.

  16. Participatory ergonomic intervention for prevention of low back pain: assembly line redesign case.

    Bernardes, João Marcos; Wanderck, Claudia; Moro, Antônio Renato Pereira


    This paper gives an overview of a participatory ergonomic intervention aimed at reducing low back pain cases in the dispatch department of a catalogue and e-commerce retail company. Based on the findings of the ergonomic analysis and design committee, the company's own employees redesigned the assembly line's layout. As a result of these changes two job tasks that involved manual material handling of boxes, identified by the revised NIOSH equation as posing an increased risk for lifting-related low back pain, were totally eliminated, and the employees responsible for moving boxes from the end of the assembly line to pallets on the ground were given more control over their jobs, and these jobs were also enriched with a new, less heavy task. These results demonstrate that participatory ergonomic interventions are a viable and effective strategy to reduce the exposure to work-related physical and psychosocial risk factors for low back pain.

  17. Fatigue Life Prediction of Horizontal Press Frame Based on Statistical Probability and Its Redesign

    WeiWei Zhang; XiaoSon Wang; Bo Yang; Shi-Jian Yuan


    Horizontal press as an important part of hydro-forming machine is used to output the horizontal force to keep the high internal pressure during tube hydro-forming. However, the horizontal press frame is usually mounted on the press bed and not pre-stressed. Meanwhile it will be subjected to the reaction force caused by liquid pressure. Stresses are concentrated severely on the assemble region due to deformation, and total fatigue life will decrease. In order to predict the total fatigue life of the frame, the simulations are used firstly to determine to stress concentration region, and then strain gauge measurements are carried out under different loads. Next, the methods of statistical probability are conducted to calculate the fatigue life based on long-term load history. Finally a structure with the considerable longer fatigue life is redesigned.

[Nuclear Engineering Teaching Laboratory, The University of Texas at Austin (United States)


    The prompt gamma activation analysis (PGAA) facility at The University of Texas at Austin (UT) has been redesigned and reconstructed. As a result of the new shielding of the system, the neutron (at all energies) and gamma-ray backgrounds have been reduced by more than an order of magnitude, considerably improving the signal-to-noise ratio for the characteristic peaks. The prompt gamma peaks from the construction materials have also been decreased, providing better detection limits for elements. The calibration of the new system is shown in detail. All these efforts significantly improved the sensitivity and reliability of the chemical analyses performed in the facility. The characteristics of the improved PGAA system are also presented.

    Pelath, R.P. [National Guard Bureau, Arlington, VA (United States); Rasch, K.A. [Oak Ridge National Lab., TN (United States)


    The Objective Supply Capability Adaptive Redesign (OSCAR) project is designed to identify and develop programs which automate requirements not included in standard army systems. This includes providing automated interfaces between standard army systems at the National Guard Bureau (NGB) level and at the state/territory level. As part of the OSCAR project, custom software has been installed at NGB to streamline management of major end items. This software allows item managers to provide automated disposition on excess equipment to states operating the Standard Army Retail Supply System Objective (SARSS-O). It also accelerates movement of excess assets to improve the readiness of the Army National Guard (ARNG)--while reducing excess on hand. The purpose of the End-User Manual is to provide direction and guidance to the customer for implementing the ARNG Excess Management Program.

  20. Redesign and Validation of Sisom, an Interactive Assessment and Communication Tool for Children With Cancer


    Background Children with cancer undergo intensive and long treatment periods that expose them and their families to a number of difficult physical, mental, and social challenges. Empowering children by actively involving them in their care can help them to cope with these challenges. It can, however, be difficult for children to be involved and talk about their illness experiences in a “traditional” conversation with health care professionals, especially for younger children. Sisom (Norwegian acronym “Si det som det er” or “Tell it how it is”) is an interactive computer-based assessment and communication tool to give children (aged 6-12 years) with cancer a “voice” in their care. Because of technological advances and widespread use of mobile devices Sisom had to be redesigned to better meet the needs of children of today. Objective To redesign Sisom for use on mobile devices and to validate and adapt it for use in a Swedish population of children with cancer. Methods A user-experience design was used. Content adaptation included forward-backward translation by Swedish and Norwegian translators. Healthy children (n=5), children with experiences of cancer treatment (n=5) and their parents (n=5), and pediatric nurses (n=2) were then involved in culturally adapting Sisom to the Swedish context. The iterative low- and high-fidelity evaluation was supported by a think aloud method, semistructured interviews, and drawings to capture children’s views of Sisom. The redesign and evaluation continued until no further changes or improvements were identified by the participants or the researchers. Results Children, parents, and pediatric nurses offered many suggestions for improvements to the original version in terms of content, aesthetics, and usability of Sisom. The most significant change that emerged through user input was a modification that entailed not using problem-focused statements in the assessment items. The parents and pediatric nurses considered

  1. Robust digital controllers for uncertain chaotic systems: A digital redesign approach

    Ababneh, Mohammad [Department of Controls, FMC Kongsberg Subsea, FMC Energy Systems, Houston, TX 77067 (United States); Barajas-Ramirez, Juan-Gonzalo [CICESE, Depto. De Electronica y Telecomunicaciones, Ensenada, BC, 22860 (Mexico); Chen Guanrong [Centre for Chaos Control and Synchronization, Department of Electronic Engineering, City University of Hong Kong (China); Shieh, Leang S. [Department of Electrical and Computer Engineering, University of Houston, Houston, TX 77204-4005 (United States)


    In this paper, a new and systematic method for designing robust digital controllers for uncertain nonlinear systems with structured uncertainties is presented. In the proposed method, a controller is designed in terms of the optimal linear model representation of the nominal system around each operating point of the trajectory, while the uncertainties are decomposed such that the uncertain nonlinear system can be rewritten as a set of local linear models with disturbed inputs. Applying conventional robust control techniques, continuous-time robust controllers are first designed to eliminate the effects of the uncertainties on the underlying system. Then, a robust digital controller is obtained as the result of a digital redesign of the designed continuous-time robust controller using the state-matching technique. The effectiveness of the proposed controller design method is illustrated through some numerical examples on complex nonlinear systems--chaotic systems.

  2. Medipix3RX: Characterizing the Medipix3 Redesign With Synchrotron Radiation

    Gimenez, Eva N; Blaj, Gabriel; Campbell, Michael; Dolbnya, Igor; Frodjh, Erik; Horswell, Ian; Llopart, Xavier; Marchal, Julien; McGrath, John; Omar, David; Plackett, Richard; Sawhney, Kawal; Tartoni, Nicola


    The Medipix3RX is the latest version of the Medipix3 photon counting ASICs, which implements two new operational modes, with respect to the Medipix2 ASIC, aimed at eliminating charge shared events (referred to as Charge Summing Mode (CSM)) and at providing spectroscopic information (referred to as Colour Mode (CM)). The Medipix3RX is a redesign of the Medipix3v0 ASIC and corrects for the underperformance of CSM features observed in the previous version. This paper presents the results from synchrotron X-rays tests to evaluate the Medipix3RX ASIC performance. The newly implemented CSM algorithm eliminates the charge sharing effect at the same time as allocating the event to the readout pixel corresponding to the sensor pixel where the X-ray photon impinged. The new pixel trimming circuit led to a reduced dispersion between pixels. Further results of the linearity for all the gain modes, energy resolution and pixel uniformity are also presented.

  4. Digital redesign of anti-wind-up controller for cascaded analog system.

    Chen, Y S; Tsai, J S H; Shieh, L S; Moussighi, M M


    The cascaded conventional anti-wind-up (CAW) design method for integral controller is discussed. Then, the prediction-based digital redesign methodology is utilized to find the new pulse amplitude modulated (PAM) digital controller for effective digital control of the analog plant with input saturation constraint. The desired digital controller is determined from existing or pre-designed CAW analog controller. The proposed method provides a novel methodology for indirect digital design of a continuous-time unity output-feedback system with a cascaded analog controller as in the case of PID controllers for industrial control processes with the presence of actuator saturations. It enables us to implement an existing or pre-designed cascaded CAW analog controller via a digital controller effectively.

  6. Sign Redesign: Applying Design Principles to Improve Signage in an Academic Library

    Sheila Kasperek


    Full Text Available When the Mansfield University library’s Special Events and Customer Service Committee created a communications plan for the library, the opportunity presented itself to overhaul the library signs. Applying basic design principles of contrast, alignment, and repetition along with standards from the Americans with Disabilities Act, the library improved the visual communications within the library. Patrons can now read signs from a distance and understand their purpose. Using common design elements, the library began presenting official library information more cohesively. Extending beyond signs, these design principles are now part of the library’s print publications and promotional items. With this consistency, the library brand is more easily recognizable both within the library and across campus. This article describes some basic elements of design and the process of redesigning the signs.

  7. A Robust Approach for Redesigning Three Level Supply Chain Warehouses in Uncertain Condition

    Mahdi Bashiri


    Full Text Available Nowadays, warehouses dedicate considerable proportion of network's costs in a supply chain and conditions such as uncertainty in cost parameters, production capacity and demands emphasize on necessity of reasonable decisions on warehouse management. In this paper, uncertainty has been investigated under discrete different scenarios. Moreover, a new model has been proposed for redesigning of warehouses considering the min-max cost function for scenarios in specific customer servicing coverage radius. The robust approach used in this paper has been investigated by numerical examples and the obtained costs have been compared with the expected value model results. Findings imply efficiency of the proposed robust approach. Also, the costs resulted from the new relocation model have been evaluated with respect to the costs of continuing the current supply chain configuration and the findings indicate a significant cost improvement.

  8. Axiomatic design theory for the analysis, comparison, and redesign of curriculum for special education.

    Wettasinghe, C M; Koh, T H


    This paper explores a novel approach to instructional planning using the axiomatic design theory to create an optimized curriculum. First, an existing piece of curriculum is analyzed by axiomatic design approach and design matrices are made to check whether the independence axiom is satisfied or not. Second, functional requirements (FRs) are derived from the FRs of the existing curriculums developed through conventional methods. Constraints (Cs) are defined considering the time and subject. Design parameters (DPs) are conceived in physical domain to satisfy these specified FRs and Cs, and two alternative DPs for one FR are proposed. One of these alternatives having the least information content is selected by defining FRs as the minimization of the irrelevant subjects/topics and time. Also feasibility is estimated by comparing the information content of the redesigned curriculum with that of other curriculums in consideration of costs-involved, time, and subjects-relevance.

  9. Redesigning and aligning assessment and evaluation for a federally funded math and science teacher educational program.

    Hardré, Patricia L; Slater, Janis; Nanny, Mark


    This paper examines the redesign of evaluation components for a teacher professional development project funded by the National Science Foundation. It focuses on aligning evaluation instrumentation and strategies with program goals, research goals and program evaluation best practices. The study identifies weaknesses in the original (year 1) program evaluation design and implementation, develops strategies and tracks changes for year 2 implementation, and then reports enhancement of findings and recommendations for year 3. It includes lessons learned about assessment and evaluation over the project lifespan, with implications for research and evaluation of a range of related programs. This study functions as a classic illustration of how critical it is to observe first principles of assessment and evaluation for funded programs, the risks that arise when they are ignored, and the benefits that accrue when they are systematically observed.

    Bell, Anthony; Cochrane, Alastair; Courtice, Sally; Flanigan, Kathy; Mathur, Mandeep; Wilckens, Daniel


    The aim of Queen Elizabeth II Jubilee Hospital (QEII) redesign project (QEII United) was to enhance timely access to an inpatient bed and maximise opportunities to value add during the inpatient episode of care. A tripartite relationship between the hospital team, system manager and external consultants. The team, QEII United, was formed to 'diagnose, solve and implement' change under the unifying metaphorical banner of a football team. A marketing strategy and communication plan targeted the key 'players' and outlined the 'game plan'. Baseline data were collected, analysed and reported in keeping with key aims. Strategies for systems improvement implementation were attached to key performance indicators (KPIs). Thematic KPIs were developed to embed internal process change to reflect the contributions made towards the National Emergency Access Target (NEAT) at each stage of the patient journey. As such, access block of under 20%, morning discharge rates of 50% before midday, reduced length of stay for selected elective orthopaedic and general medical diagnostic related groupings (DRGs; i.e. relative stay index ≤1) and hospital in the home (HITH) utilisation rates 1.5% of all admissions were all met. Key to sustainability was the transfer of clinical redesign skills to hospital staff and the fostering of emergent ground up leadership. QEII United's success has been underpinned by the development of themed solution areas developed by the hospital staff themselves. Robust baseline data analysis used in combination with nationally available benchmarking data provided a quantitative starting point for the work. The collaborative elements of the program re-energised the hospital team, who were kept informed by targeted communications, to establish quick wins and build trust and momentum for the more challenging areas.

  12. International Space Station Common Cabin Air Assembly Water Separator On-Orbit Operation, Failure, and Redesign

    Balistreri, Steven F., Jr.; Shaw, Laura A.; Laliberte, Yvon


    The ability to control the temperature and humidity of an environment or habitat is critical for human survival. These factors are important to maintaining human health and comfort, as well as maintaining mechanical and electrical equipment in good working order to support the human and to accomplish mission objectives. The temperature and humidity of the International Space Station (ISS) United States On-orbit Segment (USOS) cabin air is controlled by the Common Cabin Air Assembly (CCAA). The CCAA consists of a fan, a condensing heat exchanger (CHX), an air/water separator, temperature and liquid sensors, and electrical controlling hardware and software. The Water Separator (WS) pulls in air and water from the CHX, and centrifugally separates the mixture, sending the water to the condensate bus and the air back into the CHX outlet airstream. Two distinct early failures of the CCAA Water Separator in the Quest Airlock forced operational changes and brought about the re-design of the Water Separator to improve the useful life via modification kits. The on-orbit operational environment of the Airlock presented challenges that were not foreseen with the original design of the Water Separator. Operational changes were instituted to prolong the life of the third installed WS, while waiting for newly designed Water Separators to be delivered on-orbit. The modification kit design involved several different components of the Water Separator, including the innovative use of a fabrication technique to build the impellers used in Water Separators out of titanium instead of aluminum. The technique allowed for the cost effective production of the low quantity build. This paper will describe the failures of the Water Separators in the Quest Airlock, the operational constraints that were implemented to prolong the life of the installed Water Separators throughout the USOS, and the innovative re-design of the CCAA Water Separator.

  13. Redesigning a joint replacement program using Lean Six Sigma in a Veterans Affairs hospital.

    Gayed, Benjamin; Black, Stephen; Daggy, Joanne; Munshi, Imtiaz A


    In April 2009, an analysis of joint replacement surgical procedures at the Richard L. Roudebush Veterans Affairs Medical Center, Indianapolis, Indiana, revealed that total hip and knee replacements incurred $1.4 million in non-Veterans Affairs (VA) care costs with an average length of stay of 6.1 days during fiscal year 2008. The Joint Replacement Program system redesign project was initiated following the Vision-Analysis-Team-Aim-Map-Measure-Change-Sustain (VA-TAMMCS) model to increase efficiency, decrease length of stay, and reduce non-VA care costs. To determine the effectiveness of Lean Six Sigma process improvement methods applied in a VA hospital. Perioperative processes for patients undergoing total joint replacement were redesigned following the VA-TAMMCS model--the VA's official, branded method of Lean Six Sigma process improvement. A multidisciplinary team including the orthopedic surgeons, frontline staff, and executive management identified waste in the current processes and initiated changes to reduce waste and increase efficiency. Data collection included a 1-year baseline period and a 20-month sustainment period. The primary endpoint was length of stay; a secondary analysis considered non-VA care cost reductions. Length of stay decreased 36% overall, decreasing from 5.3 days during the preproject period to 3.4 days during the 20-month sustainment period (P Six Sigma process improvement initiatives in a surgical practice, producing a 36% sustained reduction in length of stay and completely eliminating non-VA care for total hip and knee replacements while increasing total joint replacement volume at this medical center.

  14. Commercial television bladder dysfunction.

    Vande Walle, J; Theunis, M; Renson, C; Raes, A; Hoebeke, P


    Bladderdysfunction seems to have an increasing frequency in infancy, and especially in children without obvious congenital organic or functional bladderdysfunction. The disorder seems is related with changes in our behaviour, that are stimulated by familial and social pseudo-reasons. Commercial interests and marketing play a major role. This leads to wrong dry-training, an exaggerated hygienic education, prudisheness, wrong toilet-posture, lack of time to void, post-poning, wrong drink- and void-pattern, wrong food-pattern and increasing constipation. Prevention is necessary by an adapted reeducation of parents ans society.

    Long commercialization times, high capital costs and sustained uncertainty deter investment in innovation for advanced materials. With appropriate strategies, technology and market uncertainties can be reduced, and the commercialization of advanced materials accelerated.

  17. Aerocapacitor commercialization plan



    The purpose of the Power-One Aerocapacitor Commercialization Plan is to communicate to members of management and to all employees the overall objectives of the corporation. Power-One, Inc., has participated in a US Federal Government Technology Reinvestment Project (TRP), entitled {open_quotes}Advanced Power Conversion based on the Aerocapacitor{close_quotes}: the project is a group effort, with Lawrence Livermore National Labs, GenCorp/Aerojet, PolyStor Corp. (a start-up company), and Power-One forming the consortium. The expected resulting technology is the {open_quotes}Aerocapacitor{close_quotes}, which possesses much higher performance levels than the usual capacitors on the market today. Power-One hopes to incorporate the Aerocapacitor into some of its products, hence enhancing their performance, as well as market privately-labeled aerocapacitors through its distribution channels. This document describes the details of Power-One`s plan to bring to market and commercialize the Aerocapacitor and Aerocapacitor-based products. This plan was formulated while Power-One was part of the Oerocap project. It has since pulled out of this project. What is presented in this plan is the work which was developed prior to the business decision to terminate this work.

  18. Investigate-and-redesign tasks as a context for learning and doing science and technology: A study of naive, novice and expert high school and adult designers doing product comparisons and redesign tasks

    Crismond, David Paul

    This thesis studied high school students and adults with varying degrees of design experience doing two technology investigate-and-redesign (I&R) tasks. Each involved subjects investigating products, designing experiments to compare them fairly, and then redesigning the devices. A total of 25 pairs of subjects participated in this investigation and included naive and novice high school designers, as well as naive, novice, and expert adult designers. Subjects of similar age and design experience worked in same-gender teams and met for two 2-hour sessions. The essential research question of this thesis was: "What process skills and concepts do naive, novice and expert designers use and learn when investigating devices, designing experiments, and redesigning the devices?" Three methodologies were used to gather and analyze the data: clinical interviewing (Piaget, 1929/1960), protocol analysis (Ericsson & Simon, 1984) and interaction analysis (Jordan and Henderson, 1995). The thesis provides composite case-studies of 10 of the 50 test sessions, buttressed by descriptions of performance trends for all subjects. Given the small sample sizes involved, the findings are by necessity tentative and not supported by statistical analysis: (1) I&R activities are engaging, less time-intensive complements to design-and-build tasks, which involve simple mechanical devices and carry with them a host of potential "alternative understandings" in science and technology. Much gets learned during these tasks, more involving "device knowledge" and "device inquiry skills" than "big ideas" in science and technology. (2) Redesign tasks scaffold naive and novice designers to improved performance in the multidimensional and context-specific activity of design. The performances of naive and novice designers were more like that of expert designers when redesigning existing devices than when doing start-from-scratch designing. (3) Conceptual redesign involved more analysis- than synthesis

  19. Commercial compact cyclotrons in the 90`s

    Milton, B.F.


    Cyclotrons continue to be efficient accelerators for radio-isotope production. In recent years, developments in the accelerator technology have greatly increased the practical beam current in these machines while also improving the overall system reliability. These developments combined with the development of new isotopes for medicine and industry, and a retiring of older machines indicate a strong future for commercial cyclotrons. In this paper the authors will survey recent developments in the areas of cyclotron technology, as they relate to the new generation of commercial cyclotrons. Design criteria for the different types of commercial cyclotrons will be presented, with reference to those demands that differ from those in a research oriented cyclotron project. The authors also discuss the possibility of systems designed for higher energies and capable of extracted beam currents of up to 2.0 mA.

  2. Year 2000 commercial issues

    Kratz, M.P.J.; Booth, R.T. [Bennett Jones, Calgary, AB (Canada)


    This presentation focused on commercial aspects of the Y2K including: (1) special communication issues, (2) outsourcing transactions, (3) joint ventures and the significance for the oil and gas industry, and (4) contingency planning. Communication issues involve interaction with suppliers and vendors of critical systems, liability for Y2K communications (misrepresentation, defamation, promissory estoppel, statutory liability), securities disclosure (Canadian and US SEC requirements), protected communications, protection for Year 2000 statements. Outsourcing problems highlighted include resistance of suppliers to assume responsibility for Y2K problem remediation, factors which support and negate supplier responsibility, scope of suppliers` obligation, and warranties in respect of third party software. Regarding joint ventures, questions concerning limitations on liability, supply warranties, stand-by arrangements, stockpiling inventory, indemnities, confidentiality, operator compensation versus operator risk, and insurance were raised and addressed. Among contingency planning issues the questions of Y2K legal audit, and disclosure aspects of contingency planning were the featured concerns. figs.

  3. Commercial nuclear power 1990


    This report presents the status at the end of 1989 and the outlook for commercial nuclear capacity and generation for all countries in the world with free market economies (FME). The report provides documentation of the US nuclear capacity and generation projections through 2030. The long-term projections of US nuclear capacity and generation are provided to the US Department of Energy's (DOE) Office of Civilian Radioactive Waste Management (OCRWM) for use in estimating nuclear waste fund revenues and to aid in planning the disposal of nuclear waste. These projections also support the Energy Information Administration's annual report, Domestic Uranium Mining and Milling Industry: Viability Assessment, and are provided to the Organization for Economic Cooperation and Development. The foreign nuclear capacity projections are used by the DOE uranium enrichment program in assessing potential markets for future enrichment contracts. The two major sections of this report discuss US and foreign commercial nuclear power. The US section (Chapters 2 and 3) deals with (1) the status of nuclear power as of the end of 1989; (2) projections of nuclear capacity and generation at 5-year intervals from 1990 through 2030; and (3) a discussion of institutional and technical issues that affect nuclear power. The nuclear capacity projections are discussed in terms of two projection periods: the intermediate term through 2010 and the long term through 2030. A No New Orders case is presented for each of the projection periods, as well as Lower Reference and Upper Reference cases. 5 figs., 30 tabs.

  4. Whither Commercial Nanobiosensors?

    Achyuthan, Komandoor


    The excitement surrounding the marriage of biosensors and nanotechnology is palpable even from a cursory examination of the scientific literature. Indeed, the word “nano” might be in danger of being overused and reduced to a cliché, although probably essential for publishing papers or securing research funding. The biosensor literature is littered with clever or catchy acronyms, birds being apparently favored (“CANARY”, “SPARROW”), quite apart from “electronic tongue,” “electronic nose,” and so on. Although biosensors have been around since glucose monitors were commercialized in the 1970s, the transition of laboratory research and innumerable research papers on biosensors into the world of commerce has lagged. There are several reasons for this phenomenon including the infamous “valley of death” afflicting entrepreneurs emerging from academic environment into the industrial world, where the rules for success can be radically different. In this context, musings on biosensors and especially nanobiosensors in an open access journal such as Journal of Biosensors and Bioelectronics is topical and appropriate especially since market surveys of biosensors are prohibitively expensive, sometimes running into thousands of dollars for a single copy. The contents and predictions of market share for biosensors in these reports also keep changing every time a report is published. Not only that, the market share projections for biosensors differs considerably amongst various reports. An editorial provides the opportunity to offer personal opinions and perhaps stimulate debate on a particular topic. In this sense, editorials are a departure from the rigor of a research paper. This editorial is no exception. With this preamble, it is worthwhile to stop and ponder the status of commercial biosensors and nanobiosensors.

  6. Structure-Guided Redesign Increases the Propensity of HIV Env To Generate Highly Stable Soluble Trimers

    Guenaga, Javier; Dubrovskaya, Viktoriya; de Val, Natalia; Sharma, Shailendra K.; Carrette, Barbara; Ward, Andrew B.


    ABSTRACT Due to high viral diversity, an effective HIV-1 vaccine will likely require Envs derived from multiple subtypes to generate broadly neutralizing antibodies (bNAbs). Soluble Env mimics, like the native flexibly linked (NFL) and SOSIP trimers, derived from the subtype A BG505 Env, form homogeneous, stable native-like trimers. However, other Env sequences, such as JRFL and 16055 from subtypes B and C, do so to a lesser degree. The high-resolution BG505 SOSIP crystal structures permit the identification and redesign of Env elements involved in trimer stability. Here, we identified structure trimer-derived (TD) residues that increased the propensity of the subtype B JRFL and subtype C 16055 Env sequences to form well-ordered, homogenous, and highly stable soluble trimers. The generation of these spike mimics no longer required antibody-based selection, positive or negative. Using the redesigned subtype B and C trimer representatives as respective foundations, we further stabilized the NFL TD trimers by engineering an intraprotomer disulfide linkage in the prebridging sheet, I201C-A433C (CC), that locks the gp120 in the receptor nontriggered state. We demonstrated that this disulfide pair prevented CD4 induced-conformational rearrangements in NFL trimers derived from the prototypic subtype A, B, and C representatives. Coupling the TD-based design with the engineered disulfide linkage, CC, increased the propensity of Env to form soluble highly stable spike mimics that are resistant to CD4-induced changes. These advances will allow testing of the hypothesis that such stabilized immunogens will more efficiently elicit neutralizing antibodies in small-animal models and primates. IMPORTANCE HIV-1 displays unprecedented global diversity circulating in the human population. Since the envelope glycoprotein (Env) is the target of neutralizing antibodies, Env-based vaccine candidates that address such diversity are needed. Soluble well-ordered Env mimics, typified by NFL

  7. Measuring the Impact of Active Learning in a Redesigned Large-enrollment Introductory Geoscience Survey Course

    Slater, T. F.; Slater, S. J.; Lyons, D. J.; Manhart, K.; Wehunt, M.; Kapp, J.; Richardson, R. M.


    Over the past two years, faculty in the UA Geosciences engaged in a major course redesign effort with the goal of improving student learning and attitudes while, at the same time, dramatically reducing costs of offering such a course. The course serves as an undergraduate general education science requirement. Using a reformed teaching framework of learner-centered education, the large-enrollment, introductory geosciences survey course was overhauled to include interactive lectures, just-in-time online quizzes, a next- generation textbook, and weekly discussions lead by graduate students and undergraduate peer mentors. The Geosciences Concept Inventory (GCI) was given as a pre-test/post-test to students in the pre-modified course and the reformed course to compare student learning in terms of gain scores. Although the entire 78-items were administered, divided into three forms, only the 36-items that most directly related to course content were used for analysis. Students in the unmodified course had a pre-test GCI percentage correct of 28.67 (SD=11.45, n=96) which increased to 45.26 (SD=11.76, n=84) on the post-test. After course redesign, students had a pre-test GCI percentage correct of 38.62 (SD=8.42, n=144) which increased a post-test GCI score of 48.73 (SD=7.49, n=132). Although the gains from pre-test to post-test are statistically significant, the different in post-test GCI scores between the two groups is not. This is interpreted as students' knowledge levels, insofar as the GCI can measure, were equivalent in both courses. The Likert-style Attitudes Toward Science Survey was given as an end-of-class post-test to students in the pre-modified course and as a pre-test post-test the reformed course to compare student attitudes between the courses. The average ranking on a 5-point scale as a pre-test was 3.454 (SD=1.259, n=508) whereas the post-tests for the unmodified course was 3.49 (SD=1.05, n=101) and 3.50 (SD=1.127, n=369) for the reformed course. As is

  8. Commercializing medical technology.

    Scanlon, Kevin J; Lieberman, Mark A


    As medicine moves into the 21st century, life saving therapies will move from inception into medical products faster if there is a better synergy between science and business. Medicine appears to have 50-year innovative cycles of education and scientific discoveries. In the 1880's, the chemical industry in Germany was faced with the dilemma of modernization to exploit the new scientific discoveries. The solution was the spawning of novel technical colleges for training in these new chemical industries. The impact of those new employees and their groundbreaking compounds had a profound influence on medicine and medical education in Germany between 1880 and 1930. Germany dominated international science during this period and was a training center for scientists worldwide. This model of synergy between education and business was envied and admired in Europe, Asia and America. British science soon after evolved to dominate the field of science during the prewar and post World War (1930's-1970's) because the German scientists fled Hitler's government. These expatriated scientists had a profound influence on the teaching and training of British scientists, which lead to advances in medicine such as antibiotics. After the Second World War, the US government wisely funded the development of the medical infrastructure that we see today. British and German scientists in medicine moved to America because of this bountiful funding for their research. These expatriated scientists helped drive these medical advances into commercialized products by the 1980's. America has been the center of medical education and advances of biotechnology but will it continue? International scientists trained in America have started to return to Europe and Asia. These American-trained scientists and their governments are very aware of the commercial potential of biotechnology. Those governments are now more prepared to play an active role this new science.

  9. Sport Commercialism and its Impact on Sponsorship Strategy

    Tracy Trachsler


    Full Text Available Sport commercialism has increased tremendously over the past twenty years. Major sporting events and organizations are at the point where most cannot survive without outside sponsor- ship revenue. This study on American attitudes towards sport sponsorships analyzes the increased sport commercialism’s impact on sport fans. Previous studies on sport sponsorship and commercialism showed that increased sport commercial- ism leads to a negative purchase intent although a younger fan may be resistant to the negative influence of over-commercial- ism. This study builds upon such research by comparing gen- der, age, type of sport (professional versus amateur and fan- avidity. Perhaps paradoxically, this research suggests there is no correlation between over-commercialism and sport interest across numerous demographic categories. This data of corporate influence on sport commercialism may provide insights for sport sponsors as they best position their brands to the sport avid consumer.

  10. Recipe Development Process Re-Design with ANSI/ISA-88 Batch Control Standard in the Pharmaceutical Industry

    Margherita De Minicis


    which must be appropriately shared among local laboratories and plants. To this extent, the ANSI/ISA-88 batch manufacturing standard, rising in the context of process control and automation, is rapidly becoming widely used in pharmaceutical companies. This paper presents a step-by-step approach to assessing the compliance to the ANSI/ISA-88 standard along with a BPM-oriented methodology applicable to the re-design of any generic recipe development process. Redesigning a recipe development process is a complex activity and can mask several pitfalls and criticalities. Thus, along with the methodology, some general evidence and suggestions are provided based on the experience of a project carried out in a large multinational pharmaceutical company.

  11. Enhancing the primary care team to provide redesigned care: the roles of practice facilitators and care managers.

    Taylor, Erin Fries; Machta, Rachel M; Meyers, David S; Genevro, Janice; Peikes, Deborah N


    Efforts to redesign primary care require multiple supports. Two potential members of the primary care team-practice facilitator and care manager-can play important but distinct roles in redesigning and improving care delivery. Facilitators, also known as quality improvement coaches, assist practices with coordinating their quality improvement activities and help build capacity for those activities-reflecting a systems-level approach to improving quality, safety, and implementation of evidence-based practices. Care managers provide direct patient care by coordinating care and helping patients navigate the system, improving access for patients, and communicating across the care team. These complementary roles aim to help primary care practices deliver coordinated, accessible, comprehensive, and patient-centered care.

  12. On using rational enzyme redesign to improve enzyme-mediated microbial dehalogenation of recalcitrant substances in deep-subsurface environments

    Ornstein, R.L.


    Heavily halogenated hydrocarbons are one of the most prevalent classes of man-made recalcitrant environmental contaminants and often make their way into subsurface environments. Biodegradation of heavily chlorinated compounds in the deep subsurface often occurs at extremely slow rates because native enzymes of indigenous microbes are unable to efficiently metabolize such synthetic substances. Cost-effective engineering solutions do not exist for dealing with disperse and recalcitrant pollutants in the deep subsurface (i.e., ground water, soils, and sediments). Timely biodegradation of heavily chlorinated compounds in the deep subsurface may be best accomplished by rational redesign of appropriate enzymes that enhance the ability of indigenous microbes to metabolize these substances. The isozyme family cytochromes P450 are catalytically very robust and are found in all aerobic life forms and may be active in may anaerobes as well. The author is attempting to demonstrate proof-of-principle rational enzyme redesign of cytochromes P450 to enhance biodehalogenation.


    Flaviu MEGHIŞAN


    Full Text Available The modern economic science was built around the concept of efficiency. In economy the notion of equality is strongly correlated with the notion of balance, such as the market balance when the demand equals the offer. In a broader view, the economy cannot contribute to a reflection on equity unless it re-became a moral and political science or even a philosophical economy. At present, when there is an effervescence of international transactions, we all adulate the need for morality. Everyday, all around the world, regular people are affected by the costs of ethical issues. The profit and social responsibility do not exclude reciprocally. The social value of a company is given by the well-being and the work-places generated, by the products and services offered to the consumers at a fair price in correlation with the quality. The sentimental value represents the value that a person is giving to a good, based on feelings and emotions and not on monetary values. In many cases the passions and the interests are more powerful than the moral value that animates us. A lot of commercials, if they are to say the truth, would recognize that, for them, not the clients are important but the profits.

  14. RNA-Redesign: a web server for fixed-backbone 3D design of RNA.

    Yesselman, Joseph D; Das, Rhiju


    RNA is rising in importance as a design medium for interrogating fundamental biology and for developing therapeutic and bioengineering applications. While there are several online servers for design of RNA secondary structure, there are no tools available for the rational design of 3D RNA structure. Here we present RNA-Redesign (, an online 3D design tool for RNA. This resource utilizes fixed-backbone design to optimize the sequence identity and nucleobase conformations of an RNA to match a desired backbone, analogous to fundamental tools that underlie rational protein engineering. The resulting sequences suggest thermostabilizing mutations that can be experimentally verified. Further, sequence preferences that differ between natural and computationally designed sequences can suggest whether natural sequences possess functional constraints besides folding stability, such as cofactor binding or conformational switching. Finally, for biochemical studies, the designed sequences can suggest experimental tests of 3D models, including concomitant mutation of base triples. In addition to the designs generated, detailed graphical analysis is presented through an integrated and user-friendly environment.

  15. Delivery and Payment Redesign to Reduce Disparities in High Risk Postpartum Care.

    Howell, Elizabeth A; Padrón, Norma A; Beane, Susan J; Stone, Joanne; Walther, Virginia; Balbierz, Amy; Kumar, Rashi; Pagán, José A


    Purpose This paper describes the implementation of an innovative program that aims to improve postpartum care through a set of coordinated delivery and payment system changes designed to use postpartum care as an opportunity to impact the current and future health of vulnerable women and reduce disparities in health outcomes among minority women. Description A large health care system, a Medicaid managed care organization, and a multidisciplinary team of experts in obstetrics, health economics, and health disparities designed an intervention to improve postpartum care for women identified as high-risk. The program includes a social work/care management component and a payment system redesign with a cost-sharing arrangement between the health system and the Medicaid managed care plan to cover the cost of staff, clinician education, performance feedback, and clinic/clinician financial incentives. The goal is to enroll 510 high-risk postpartum mothers. Assessment The primary outcome of interest is a timely postpartum visit in accordance with NCQA healthcare effectiveness data and information set guidelines. Secondary outcomes include care process measures for women with specific high-risk conditions, emergency room visits, postpartum readmissions, depression screens, and health care costs. Conclusion Our evidence-based program focuses on an important area of maternal health, targets racial/ethnic disparities in postpartum care, utilizes an innovative payment reform strategy, and brings together insurers, researchers, clinicians, and policy experts to work together to foster health and wellness for postpartum women and reduce disparities.

  16. Identification and rational redesign of peptide ligands to CRIP1, a novel biomarker for cancers.

    Jihua Hao

    Full Text Available Cysteine-rich intestinal protein 1 (CRIP1 has been identified as a novel marker for early detection of cancers. Here we report on the use of phage display in combination with molecular modeling to identify a high-affinity ligand for CRIP1. Panning experiments using a circularized C7C phage library yielded several consensus sequences with modest binding affinities to purified CRIP1. Two sequence motifs, A1 and B5, having the highest affinities for CRIP1, were chosen for further study. With peptide structure information and the NMR structure of CRIP1, the higher-affinity A1 peptide was computationally redesigned, yielding a novel peptide, A1M, whose affinity was predicted to be much improved. Synthesis of the peptide and saturation and competitive binding studies demonstrated approximately a 10-28-fold improvement in the affinity of A1M compared to that of either A1 or B5 peptide. These techniques have broad application to the design of novel ligand peptides.

  17. Redesigning a Neuroscience Laboratory Course for Multiple Sections: An Action Research Project to Engage Students.

    Tu, Hsiao-Wei; Jones, Brett D


    The purpose of our action research project was to improve students' motivation in a multi-section introductory neuroscience laboratory course. In this paper, we present: (a) how we collected data related to students' motivation and engagement, (b) how we analyzed and used the data to make modifications to the courses, (c) the results of the course modifications, and (d) some possible explanations for our results. Our aim is not only to provide the results of our study, but also to explain the process that we used, with the hopes that other instructors can use similar approaches to improve students' motivation in their courses. Our attempts to improve students' motivation-related perceptions were successful in some instances, but not in others. Of particular note was our finding that some of the students' perceptions varied even though the course syllabus was the same across sections. We attributed this variation to the learning environment developed by the teaching assistants (TAs) who taught the different sections. We provide some strategies that faculty instructors can use to redesign courses with high enrollments and help TAs motivate their students.

  18. Digital utopias and real cities—computer-generated images in re-design of public space

    Marianna Michałowska


    Full Text Available Virtual environments are seen nowadays as extensions of our physical activities in the city. Are people, however, aware what the digitally mediated cities they live in are? The starting point of my paper is a question of how computer-generated images (CGIs influence human perception of real space. I am interested in the conflict between a vision and reality, which occurs when an architectural project materialises in a public space and is subsequently rejected by the inhabitants. To explain this conflict, I will use the notion of digital utopias and compare CGIs with the great tradition of “paper” architecture. I will analyse two case studies from a medium-sized Polish city—Poznań. The first case is a redevelopment of the Main Railway Station; the second is a re-design of a local square in Poznań. The analysis focuses on the ambiguity of CGIs used to advertise new investments. The Station in the phase of digital visualisation was appreciated by the Poznań inhabitants but when the project was finally realised, strong criticism of its users followed. The second one provoked public protests already in the phase of visualisation. In conclusion, I state that the concept of agonistic public spaces should be expanded and its virtual dimension should be taken into consideration as well. When dealing with hyper-realistic CGIs, we experience a certain utopia. Confronted with their material execution, we often experience dystopian disillusion which stirs us into action.

    The automobile is a tremendous consumer of energy. The entire transport sector uses 26% of the energy and half the oil in the USA. In fact, the American auto alone consumes one-ninth of all the oil used in the world today. Since our present land use patterns lock us into intensive auto use the best approach is to redesign the auto for vastly better fuel economy. By 1985, auto makers will have to have cars that average 27.5 mpg. And beyond that, the Federal DOT wants to produce autos that average 50 mpg. Among things the auto industry is developing: cars to run on new fuels, e.g., gasohol, methanol, ethanol, and liquid fuels derived from coal and oil shale; new auto engines that are vastly more efficient and can burn a variety of fuels, e.g., the Stirling engine and the gas turbine; the electric auto and the hybrid auto (combination electric and engine powered vehicle); the flywheel as a means of storing energy normally wasted in braking; lighter cars using weight-saving materials such as high-strength steels, fiber-reinforced plastics, aluminum, etc.

  20. Redesigning service delivery for hypertensive patients: a methodological guideline to improve the management of chronic diseases.

    Ippolito, Adelaide; Cannavacciuolo, Lorella; Ponsiglione, Cristina; De Luca, Nicola; Iaccarino, Guido; Illario, Maddalena


    Best care is not necessarily the most expensive, but the most appropriate, and prevention is the most powerful tool to promote health. A novel approach might envision the reduction of hospital admittance (thus meeting a requirement from long term condition patients: they would rather not being hospitalized!) and the enforcement of peripheral (both on the territory and at home) assistance. In this direction, experiences of reshaping new service deliveries towards an integrated disease management, namely clinical pathways, can be observed in Europe and in different parts of the world. Aim of this paper is to provide a methodological guideline to support the management in planning clinical pathways, also outlining the main barriers limiting the process. In particular, we present the results of planning a clinical pathway at the Centre for Hypertension of the Federico II University Hospital (Naples, Italy). The case study showed that the introduction of a similar service impacts on the organisation of the structure. An analysis of organizational processes "as are" and the re-design of processes "to be" are necessary to integrate the clinical pathway into the actual activities.

  1. Ontologies and Formation Spaces for Conceptual ReDesign of Systems

    J. Bíla


    Full Text Available This paper discusses ontologies, methods for developing them and languages for representing them. A special ontology for computational support of the Conceptual ReDesign Process (CRDP is introduced with a simple illustrative example of an application. The ontology denoted as Global context (GLB combines features of general semantic networks and features of UML language. The ontology is task-oriented and domain-oriented, and contains three basic strata – GLBExpl(stratum of Explanation, GLBFAct (stratum of Fields of Activities and GLBEnv (stratum of Environment, with their sub-strata. The ontology has been developed to represent functions of systems and their components in CRDP. The main difference between this ontology and ontologies which have been developed to identify functions (the semantic details in those ontologies must be as deep as possible is in the style of the description of the functions. In the proposed ontology, Formation Spaces were used as lower semantic categories the semantic deepness of which is variable and depends on the actual solution approach of a specialised Conceptual Designer.

  2. The re-design of a theophylline riboswitch for DNT sensing

    Chushak, Yaroslav; Kelley-Loughnane, Nancy; Harbaugh, Svetlana; Stone, Morley


    Riboswitches are noncoding elements of mRNA that recognize and bind to small molecules and regulate the translation process of downstream genes. As an initial study, we used a theophylline riboswitch that regulates the expression of the Tobacco etch virus (TEV) protease placed downstream of the switch as a controlling element. Upon expression of TEV protease, an optical reporter is cleaved producing change in fluorescence resonance energy transfer (FRET) between BFP and eGFP. We altered the sensing domain of the original construct to create a synthetic riboswitch that responds to the presence of 2,4-dinitrotoluene (DNT) molecules. Computational analysis using Autodock4 and AMBER9 software packages showed that U24A mutant has a significantly higher binding affinity for DNT molecule compared to the original theophylline. Cells expressing the re-designed riboswitch showed a marked optical difference in fluorescence emission in the presence of DNT molecules, leading to the potential of using this construct in biosentinel applications of highly nitrated compounds.

  3. Psychological Science and Innovative Strategies for Informing Health Care Redesign: A Policy Brief

    Asarnow, Joan Rosenbaum; Hoagwood, Kimberly E.; Stancin, Terry; Lochman, John E.; Hughes, Jennifer L.; Miranda, Jeanne M.; Wysocki, Tim; Portwood, Sharon G.; Piacentini, John; Tynan, Douglas; Atkins, Marc; Kazak, Anne E.


    Recent health care legislation and shifting health care financing strategies are transforming health and behavioral health (a broad term referring to mental health, substance use, and health behavior) care in the United States. Advances in knowledge regarding effective treatment and services coupled with incentives for innovation in health and behavioral health care delivery systems make this a unique time for mobilizing our science to enhance the success of health and behavioral health care redesign. To optimize the potential of our current health care environment, a team was formed composed of leaders from the Societies of Clinical Child & Adolescent Psychology, Pediatric Psychology, and Child and Family Policy and Practice (Divisions 53, 54, and 37 of the American Psychological Association). This team was charged with reviewing the scientific and policy literature with a focus on five major issues: (a) improving access to care and reducing health disparities, (b) integrating behavioral health care within primary care, (c) preventive services, (d) enhancing quality and outcomes of care, and (e) training and workforce development. The products of that work are summarized here, including recommendations for future research, clinical, training, and policy directions. We conclude that the current emphasis on accountable care and evaluation of the outcomes of care offer numerous opportunities for psychologists to integrate science and practice for the benefit of our children, families, and nation. The dramatic changes that are occurring in psychological and behavioral health care services and payment systems also require evolution in our practice and training models. PMID:26430948

  4. Measuring sustainability within the Veterans Administration Mental Health System Redesign initiative.

    Ford, James H; Krahn, Dean; Wise, Meg; Oliver, Karen Anderson


    To examine how attributes affecting sustainability differ across Veterans Health Administration organizational components and by staff characteristics. Surveys of 870 change team members and 50 staff interviews within the Veterans Affairs' Mental Health System Redesign initiative. A 1-way ANOVA with a Tukey post hoc test examined differences in sustainability by Veteran Integrated Service Networks, job classification, and tenure from staff survey data of the Sustainability Index. Qualitative interviews used an iterative process to identify "a priori" and "in vivo" themes. A simple stepwise linear regression explored predictors of sustainability. Sustainability differed across Veteran Integrated Service Networks and staff tenure. Job classification differences existed for the following: (1) benefits and credibility of the change and (2) staff involvement and attitudes toward change. Sustainability barriers were staff and institutional resistance and nonsupportive leadership. Facilitators were commitment to veterans, strong leadership, and use of quality improvement tools. Sustainability predictors were outcomes tracking, regular reporting, and use of Plan, Do, Study, Adjust cycles. Creating homogeneous implementation and sustainability processes across a national health system is difficult. Despite the Veterans Affairs' best evidence-based implementation efforts, there was significant variance. Locally tailored interventions might better support sustainability than "one-size-fits-all" approaches. Further research is needed to understand how participation in a quality improvement collaborative affects sustainability.

  5. Models and Design Judgment: Conflicting Perspectives on Redesigning a Doctoral Readings Course

    Colin M. Gray


    Full Text Available The purpose of this project was to document the redesign of an existing doctoral reading course for an online environment. Potential methods for actualizing the proposed course structure in an online environment, including technology tools and interactions are discussed. The design process began within the framework of the Four-Component Instructional Design (4C/ID model (van Merriënboer, 1997; van Merriënboer & Kirchner, 2007, which advocates a shift from topic-centeredness to a task-centered course organization, but quickly evolved into a flexible, iterative design process that was informed by prototyping, the judgment of the design team, and various theories of knowledge and knowing. The 4C/ID model represented our philosophical starting point, but our focus quickly shifted to a more flexible, eclectic process as we attempted to reconcile conflicting constraints on the final design. Along with the redevelopment of course objectives to meet strategic goals within the doctoral program came a focus on facilitating research thinking of the students rather than teaching isolated research tasks. The design process resulted in changes to the current residential course, which then provided an opportunity for further investigation.

  6. Re-design, re-use and recycle of temporary houses

    Arslan, Hakan [Department of Construction, Faculty of Technical Education, University of Abant Izzet Baysal, Duzce 81100 (Turkey)


    Disasters are recurring to global problems, which results in homelessness. The affected region had economical, environmental and social problems as well. In relief and reconstruction phases, the need for integrated management appeared in order to use the national sources actively and productively. Especially housing implementations had an important role for future development of the affected region. For accelerating the reconstruction of the region and forming a sustainable community, which maintains itself socially, environmentally and economically over time; energy usage for construction should be kept to a minimum. Past research in Turkey shows that the cost of temporary houses (to be used as the short term shelter) had a ratio of 10-15% of the total expenses of whole construction activity. For saving money and protecting the environment and conserving scarce resources, the affected region must consider the option of temporary houses to meet their short and long-term need during the reconstruction process. After the end of usage, temporary houses should be able to be re-used for the same or new function. This study is a test of re-design and re-use of a temporary housing site; by using recycled materials, minimum energy and voluntary participation so that this site can finally become a permanent housing site.

  9. Overcoming Barriers to Successfully Commercializing Carbon Dioxide Utilization

    Marvin Kant


    Full Text Available The successful transition to a low-carbon economy hinges on innovative solutions and collaborative action on a global scale. Sustainable entrepreneurship is thereby recognized as a key driver in the creation and transformation of ecologically and socially sustainable economic systems. The purpose of this article is to contribute to this topic by understanding commercialization barriers for strong sustainability-oriented new technology ventures and to derive recommendations to overcome them. A qualitative multilevel approach is applied to identify barriers and drivers within the internal dynamic capabilities of the organization and within the organization’s external stakeholders. A model of barriers has been developed based on semi-structured interviews with new carbon dioxide utilization ventures and associated industry players in Canada, the USA, and the European Economic Area. Resulting recommendations to facilitate the (re-design of a dedicated support system are proposed on four levels: (a actors, (b resources, (c institutional settings, and (d the coordination of the support system.

  10. Patients-people-place: developing a framework for researching organizational culture during health service redesign and change.

    Gale, Nicola K; Shapiro, Jonathan; McLeod, Hugh S T; Redwood, Sabi; Hewison, Alistair


    Organizational culture is considered by policy-makers, clinicians, health service managers and researchers to be a crucial mediator in the success of implementing health service redesign. It is a challenge to find a method to capture cultural issues that is both theoretically robust and meaningful to those working in the organizations concerned. As part of a comparative study of service redesign in three acute hospital organizations in England, UK, a framework for collecting data reflective of culture was developed that was informed by previous work in the field and social and cultural theory. As part of a larger mixed method comparative case study of hospital service redesign, informed by realist evaluation, the authors developed a framework for researching organisational culture during health service redesign and change. This article documents the development of the model, which involved an iterative process of data analysis, critical interdisciplinary discussion in the research team, and feedback from staff in the partner organisations. Data from semi-structured interviews with 77 key informants are used to illustrate the model. In workshops with NHS partners to share and debate the early findings of the study, organizational culture was identified as a key concept to explore because it was perceived to underpin the whole redesign process. The Patients-People-Place framework for studying culture focuses on three thematic areas ('domains') and three levels of culture in which the data could be organised. The framework can be used to help explain the relationship between observable behaviours and cultural artefacts, the values and habits of social actors and the basic assumptions underpinning an organization's culture in each domain. This paper makes a methodological contribution to the study of culture in health care organizations. It offers guidance and a practical approach to investigating the inherently complex phenomenon of culture in hospital organizations

  12. Accounting Education Approach in the Context of New Turkish Commercial Code and Turkish Accounting Standards

    Cevdet Kızıl


    Full Text Available The aim of this article is to investigate the impact of new Turkish commercial code and Turkish accounting standards on accounting education. This study takes advantage of the survey method for gathering information and running the research analysis. For this purpose, questionnaire forms are distributed to university students personally and via the internet.This paper includes significant research questions such as “Are accounting academicians informed and knowledgeable on new Turkish commercial code and Turkish accounting standards?”, “Do accounting academicians integrate new Turkish commercial code and Turkish accounting standards to their lectures?”, “How does modern accounting education methodology and technology coincides with the teaching of new Turkish commercial code and Turkish accounting standards?”, “Do universities offer mandatory and elective courses which cover the new Turkish commercial code and Turkish accounting standards?” and “If such courses are offered, what are their names, percentage in the curriculum and degree of coverage?”Research contributes to the literature in several ways. Firstly, new Turkish commercial code and Turkish accounting standards are current significant topics for the accounting profession. Furthermore, the accounting education provides a basis for the implementations in public and private sector. Besides, one of the intentions of new Turkish commercial code and Turkish accounting standards is to foster transparency. That is definitely a critical concept also in terms of mergers, acquisitions and investments. Stakeholders of today’s business world such as investors, shareholders, entrepreneurs, auditors and government are in need of more standardized global accounting principles Thus, revision and redesigning of accounting educations plays an important role. Emphasized points also clearly prove the necessity and functionality of this research.

    Gisbergen, M.S. van; Ketelaar, P.E.; Baudoin, P,


    Viral commercials werken goed. De meeste jongeren bekijken viral commercials en beoordelen ze positiever dan tv-commercials. Doordat viral commercials volgens consumenten voor vermaak zorgen, ontwijken zij ze minder dan tv-commercials. Ook onthouden jongeren de in viral commercials geadverteerde producten en merken goed. Dit blijkt uit onderzoek van de Radboud Universiteit in samenwerking met De Vos & Jansen onder 412 jongeren.

  16. NASA's approach to space commercialization

    Gillam, Isaac T., IV


    The NASA Office of Commercial Programs fosters private participation in commercially oriented space projects. Five Centers for the Commercial Development of Space encourage new ideas and perform research which may yield commercial processes and products for space ventures. Joint agreements allow companies who present ideas to NASA and provide flight hardware access to a free launch and return from orbit. The experimenters furnish NASA with sufficient data to demonstrate the significance of the results. Ground-based tests are arranged for smaller companies to test the feasibility of concepts before committing to the costs of developing hardware. Joint studies of mutual interest are performed by NASA and private sector researchers, and two companies have signed agreements for a series of flights in which launch costs are stretched out to meet projected income. Although Shuttle flights went on hold following the Challenger disaster, extensive work continues on the preparation of commercial research payloads that will fly when Shuttle flights resume.

    Warley Marcos Nascimento


    Full Text Available A abóbora tipo “Tetsukabuto” é um híbrido interespecífico, macho estéril, resultante do cruzamento entre Cucurbita maxima e C. moschata. Uma das estratégias utilizadas para produção comercial de frutos de “Tetsukabuto” tem sido o plantio adjacente e concomitante de acessos de C. maxima ou C. moschata como polinizadores. Este trabalho teve por objetivo avaliar a eficiência de diferentes acessos de C. maxima como fontes de pólen para produção comercial de abóbora tipo “Tetsukabuto”. A cultivar de moranga "Exposição" e o acesso "Nirvana" foram utilizados como polinizadores para produção de frutos de dois híbridos do tipo varietal “Tetsukabuto” ("Jabras" e "Kyoto". Foram avaliados os tratamentos (cruzamentos Jabras x Exposição, Jabras x Nirvana, Tetsukabuto x Exposição, Tetsukabuto x Nirvana, em quatro repetições. Foram determinados os parâmetros massa dos frutos, diâmetro dos frutos, espessura da polpa, número e massa de sementes. O acesso "Nirvana" (cultivar em fase de validação pode ser utilizado na produção comercial como polinizador de abóboras deste grupo varietal sem nenhum prejuízo quando comparado com a moranga "Exposição"."Tetsukabuto" pumpkins are interspecific hybrids between Cucurbita maxima x C. moschata accessions. Such hybrids, however, are often male-sterile due to the impaired ability of the staminate flowers to produce functional pollen. The use of intervening rows of staminate (pollen-donor plants is one strategy employed in order to have commercial fruit production. In the present work, two C. maxima accessions ["Exposição" (E and "Nirvana" (N] were employed as pollen-donors (staminate parents and their efficiency was compared considering fruit and seed yield parameters. Two pistillate Tetsukabuto hybrids ["Jabras" (J and "Kyoto Tetsukabuto" (KT] were employed in four possible unidirectional crosses (J x E, J x N, KT x E and KT x N.

  18. Rationally re-designed mutation of NAD-independent l-lactate dehydrogenase: high optical resolution of racemic mandelic acid by the engineered Escherichia coli

    Jiang Tianyi


    Full Text Available Abstract Background NAD-independent l-lactate dehydrogenase (l-iLDH from Pseudomonas stutzeri SDM can potentially be used for the kinetic resolution of small aliphatic 2-hydroxycarboxylic acids. However, this enzyme showed rather low activity towards aromatic 2-hydroxycarboxylic acids. Results Val-108 of l-iLDH was changed to Ala by rationally site-directed mutagenesis. The l-iLDH mutant exhibited much higher activity than wide-type l-iLDH towards l-mandelate, an aromatic 2-hydroxycarboxylic acid. Using the engineered Escherichia coli expressing the mutant l-iLDH as a biocatalyst, 40 g·L-1 of dl-mandelic acid was converted to 20.1 g·L-1 of d-mandelic acid (enantiomeric purity higher than 99.5% and 19.3 g·L-1 of benzoylformic acid. Conclusions A new biocatalyst with high catalytic efficiency toward an unnatural substrate was constructed by rationally re-design mutagenesis. Two building block intermediates (optically pure d-mandelic acid and benzoylformic acid were efficiently produced by the one-pot biotransformation system.

  19. Highly stereoselective biosynthesis of (R)-α-hydroxy carboxylic acids through rationally re-designed mutation of D-lactate dehydrogenase.

    Zheng, Zhaojuan; Sheng, Binbin; Gao, Chao; Zhang, Haiwei; Qin, Tong; Ma, Cuiqing; Xu, Ping


    An NAD-dependent D-lactate dehydrogenase (D-nLDH) of Lactobacillus bulgaricus ATCC 11842 was rationally re-designed for asymmetric reduction of a homologous series of α-keto carboxylic acids such as phenylpyruvic acid (PPA), α-ketobutyric acid, α-ketovaleric acid, β-hydroxypyruvate. Compared with wild-type D-nLDH, the Y52L mutant D-nLDH showed elevated activities toward unnatural substrates especially with large substitutes at C-3. By the biocatalysis combined with a formate dehydrogenase for in situ generation of NADH, the corresponding (R)-α-hydroxy carboxylic acids could be produced at high yields and highly optical purities. Taking the production of chiral (R)-phenyllactic acid (PLA) from PPA for example, 50 mM PPA was completely reduced to (R)-PLA in 90 min with a high yield of 99.0% and a highly optical purity (>99.9% e.e.) by the coupling system. The results presented in this work suggest a promising alternative for the production of chiral α-hydroxy carboxylic acids.

  20. The flipped classroom: a course redesign to foster learning and engagement in a health professions school.

    McLaughlin, Jacqueline E; Roth, Mary T; Glatt, Dylan M; Gharkholonarehe, Nastaran; Davidson, Christopher A; Griffin, LaToya M; Esserman, Denise A; Mumper, Russell J


    Recent calls for educational reform highlight ongoing concerns about the ability of current curricula to equip aspiring health care professionals with the skills for success. Whereas a wide range of proposed solutions attempt to address apparent deficiencies in current educational models, a growing body of literature consistently points to the need to rethink the traditional in-class, lecture-based course model. One such proposal is the flipped classroom, in which content is offloaded for students to learn on their own, and class time is dedicated to engaging students in student-centered learning activities, like problem-based learning and inquiry-oriented strategies. In 2012, the authors flipped a required first-year pharmaceutics course at the University of North Carolina Eshelman School of Pharmacy. They offloaded all lectures to self-paced online videos and used class time to engage students in active learning exercises. In this article, the authors describe the philosophy and methodology used to redesign the Basic Pharmaceutics II course and outline the research they conducted to investigate the resulting outcomes. This article is intended to serve as a guide to instructors and educational programs seeking to develop, implement, and evaluate innovative and practical strategies to transform students' learning experience. As class attendance, students' learning, and the perceived value of this model all increased following participation in the flipped classroom, the authors conclude that this approach warrants careful consideration as educators aim to enhance learning, improve outcomes, and fully equip students to address 21st-century health care needs.

  1. A data fusion-based methodology for optimal redesign of groundwater monitoring networks

    Hosseini, Marjan; Kerachian, Reza


    In this paper, a new data fusion-based methodology is presented for spatio-temporal (S-T) redesigning of Groundwater Level Monitoring Networks (GLMNs). The kriged maps of three different criteria (i.e. marginal entropy of water table levels, estimation error variances of mean values of water table levels, and estimation values of long-term changes in water level) are combined for determining monitoring sub-areas of high and low priorities in order to consider different spatial patterns for each sub-area. The best spatial sampling scheme is selected by applying a new method, in which a regular hexagonal gridding pattern and the Thiessen polygon approach are respectively utilized in sub-areas of high and low monitoring priorities. An Artificial Neural Network (ANN) and a S-T kriging models are used to simulate water level fluctuations. To improve the accuracy of the predictions, results of the ANN and S-T kriging models are combined using a data fusion technique. The concept of Value of Information (VOI) is utilized to determine two stations with maximum information values in both sub-areas with high and low monitoring priorities. The observed groundwater level data of these two stations are considered for the power of trend detection, estimating periodic fluctuations and mean values of the stationary components, which are used for determining non-uniform sampling frequencies for sub-areas. The proposed methodology is applied to the Dehgolan plain in northwestern Iran. The results show that a new sampling configuration with 35 and 7 monitoring stations and sampling intervals of 20 and 32 days, respectively in sub-areas with high and low monitoring priorities, leads to a more efficient monitoring network than the existing one containing 52 monitoring stations and monthly temporal sampling.

  2. The need for redesigned pharmacy practice courses in Pakistan: the perspectives of senior pharmacy students

    Muhammad Umair Khan


    Full Text Available Purpose: In Pakistan, courses in pharmacy practice, which are an essential component of the PharmD curriculum, were launched with the aim of strengthening pharmacy practice overall and enabling pharmacy students to cope with the challenges involved in meeting real-world healthcare needs. Since very little research has assessed the efficacy of such courses, we aimed to evaluate students’ perceptions of pharmacy practice courses and their opinions about whether their current knowledge of the topics covered in pharmacy practice courses is adequate for future practice. Methods: A cross-sectional study was conducted over two months among the senior pharmacy students of two pharmacy colleges. A content- and face-validated questionnaire was used to collect data, which were then analysed using SPSS version 20. Descriptive analysis and logistic regression were performed. Results: Research in pharmacy practice (30.2%, applied drug information (34.4%, health policy (38.1%, public health and epidemiology (39.5%, pharmacovigilance (45.6%, and pharmacoeconomics (47.9% were the major courses that were covered to the least extent in the PharmD curriculum. However, hospital pharmacy practice (94.4%, pharmacotherapeutics (88.8%, and community pharmacy practice (82.8% were covered well. Although 94% of students considered these courses important, only 37.2% considered themselves to be competent in the corresponding topics. Of the participants, 87.9% agreed that the pharmacy courses in the present curriculum should be redesigned. Conclusion: Our results showed that the pharmacy practice courses in the current PharmD curriculum do not encompass some important core subjects. A nationwide study is warranted to further establish the necessity for remodelling pharmacy practice courses in Pakistan.

  3. Combining in silico evolution and nonlinear dimensionality reduction to redesign responses of signaling networks

    Prescott, Aaron M.; Abel, Steven M.


    The rational design of network behavior is a central goal of synthetic biology. Here, we combine in silico evolution with nonlinear dimensionality reduction to redesign the responses of fixed-topology signaling networks and to characterize sets of kinetic parameters that underlie various input-output relations. We first consider the earliest part of the T cell receptor (TCR) signaling network and demonstrate that it can produce a variety of input-output relations (quantified as the level of TCR phosphorylation as a function of the characteristic TCR binding time). We utilize an evolutionary algorithm (EA) to identify sets of kinetic parameters that give rise to: (i) sigmoidal responses with the activation threshold varied over 6 orders of magnitude, (ii) a graded response, and (iii) an inverted response in which short TCR binding times lead to activation. We also consider a network with both positive and negative feedback and use the EA to evolve oscillatory responses with different periods in response to a change in input. For each targeted input-output relation, we conduct many independent runs of the EA and use nonlinear dimensionality reduction to embed the resulting data for each network in two dimensions. We then partition the results into groups and characterize constraints placed on the parameters by the different targeted response curves. Our approach provides a way (i) to guide the design of kinetic parameters of fixed-topology networks to generate novel input-output relations and (ii) to constrain ranges of biological parameters using experimental data. In the cases considered, the network topologies exhibit significant flexibility in generating alternative responses, with distinct patterns of kinetic rates emerging for different targeted responses.

  4. Forty research issues for the redesign of animal production systems in the 21st century.

    Dumont, B; González-García, E; Thomas, M; Fortun-Lamothe, L; Ducrot, C; Dourmad, J Y; Tichit, M


    Agroecology offers a scientific and operational framework for redesigning animal production systems (APS) so that they better cope with the coming challenges. Grounded in the stimulation and valorization of natural processes to reduce inputs and pollutions in agroecosystems, it opens a challenging research agenda for the animal science community. In this paper, we identify key research issues that define this agenda. We first stress the need to assess animal robustness by measurable traits, to analyze trade-offs between production and adaptation traits at within-breed and between-breed level, and to better understand how group selection, epigenetics and animal learning shape performance. Second, we propose research on the nutritive value of alternative feed resources, including the environmental impacts of producing these resources and their associated non-provisioning services. Third, we look at how the design of APS based on agroecological principles valorizes interactions between system components and promotes biological diversity at multiple scales to increase system resilience. Addressing such challenges requires a collection of theories and models (concept-knowledge theory, viability theory, companion modeling, etc.). Acknowledging the ecology of contexts and analyzing the rationales behind traditional small-scale systems will increase our understanding of mechanisms contributing to the success or failure of agroecological practices and systems. Fourth, the large-scale development of agroecological products will require analysis of resistance to change among farmers and other actors in the food chain. Certifications and market-based incentives could be an important lever for the expansion of agroecological alternatives in APS. Finally, we question the suitability of current agriculture extension services and public funding mechanisms for scaling-up agroecological practices and systems.

  5. Redesigning the continuous vacuum sealer packaging machine to improve the processing speed

    Belo, J. B.; Widyanto, S. A.; Jamari, J.


    Vacuum sealer as a product packaging tool of food products to be able to vacuum air inside the plastic which is filled with food products and it causes the pressure lower. In this condition, the optimal heating temperature is reached in a shorter time, so that damage on plastic sealer of vacuumed food products could be prevented to be more effective and efficient. The purpose of this redesigning is to design a vacuum sealer packaging machine continuously through a conveyor mechanism on the packaging quality, time of processing speed of vacuuming food product in the plastic package. This designing process is conducted through several steps of designing and constructing tools until the products are ready to operate. Data analysis is done through quality test of vacuum and sealer to the plastic thickness of 75 µm, 80 µm, and 100 µm with temperature of 170°C, 180°C, 190°C and vacuum duration of 5 seconds, 8 seconds, and 60 seconds. Results of this designing process indicate that vacuum sealer works practically and more optimally with the time of vacuum processing speed of 0 to 1 minute/s; whereas, the pressure of vacuuming suction is until 1e-5 MPa. The results of tensile strength test are at a maximum of 32,796 (N/mm2) and a minimum of 20,155 (N/mm2) and the analysis of plastic composite with EDX. This result shows that the vacuum pressure and the quality of vacuum sealer are better and more efficient.

  6. Why medical education is being (inexorably) re-imagined and re-designed.

    Mahan, John D; Clinchot, Daniel


    The last widespread reimagining and substantive reform in medical student education followed the Flexner Report (published 1910). Given the dramatic changes in educational methods, pedagogy, and technology, and the dramatic changes in society, medical education has inexorably evolved in intentional and unintentional ways. The transition from the post-Flexnerian model (university-based education with the first 2 years organized around classroom didactics, laboratory/anatomy learning followed by 2 years of inpatient and outpatient clinical experiences organized around a distribution of block and elective rotations) to the models of today (highlighting early clinical exposure, integration of foundational and clinical sciences, longitudinal learning experiences, promotion of self-directed learning skills, and competency-based education) is underway. The focus now is to prepare graduates for the continued explosion of medical knowledge, technological development and expanded patient and societal expectations that increasingly characterize this century. The following five important developments in medical education drive these re-imaging and re-design efforts: (1) patient, societal and governmental pressure to deliver on the Triple Aim; (2) conceptualization of medical education as a translational science; (3) medical knowledge and technology will continue to expand and accelerate the pace of new development; (4) new expectations of present and future generations of learners; and (5) better understanding of the neurobiology of learning. The impact of these developments, and our responses as those dedicated to educating the present and future physicians, will determine much of the outcomes in this journey to evidence-based medical education. With all of the information and techniques available to the inquisitive and diligent teacher, there will be ample rewards for teaching well done.

  8. [Redesign of the Spacesuit Long Life Battery and the Personal Life Support System Battery

    Scharf, Stephanie


    This fall I was working on two different projects that culminated into a redesign of the spacesuit LLB (long life battery). I also did some work on the PLSS (personal life support system) battery with EC. My first project was redlining the work instruction for completing DPAs (destructive physical analysis) on battery cells in the department. The purpose of this document is to create a standard process and ensure that the data in the same way no matter who carries out the analysis. I observed three DPAs, conducted one with help, and conducted two on my own all while taking notes on the procedure. These notes were used to write the final work instruction that will become is the department standard. My second project continued the work of the summer co-op before me. I was testing aluminum heat sinks for their ability to provide good thermal conduction and structural support during a thermal runaway event. The heat sinks were designed by the summer intern but there was not much time for testing before he left. We ran tests with a heater on the bottom of a trigger cell to try to drive thermal runaway and ensure that it will not propagate to adjacent cells. We also ran heat-to-vent tests in an oven to see if the assembly provided structural support and prevented sidewall rupture during thermal runaway. These tests were carried out at ESTA (energy systems test area) and are providing very promising results that safe, high performing (greater than 180 Wh/kg) designs are possible. My main project was a redesign of the LLB battery. Another summer intern did some testing and concluded that there was no simple fix to mitigate thermal runaway propagation hazards in the current design. The only option was a clean sheet redesign of the battery. I was given a volume and ideal energy density and the rest of the design was up to me. First, I created new heat sink banks in Creo using the information gathered in the metal heat sink tests from the summer intern. After this, I made

  9. Campylobacter jejuni in commercial eggs

    Belchiolina Beatriz Fonseca


    Full Text Available This study evaluated the ability of Campylobacter jejuni to penetrate through the pores of the shells of commercial eggs and colonize the interior of these eggs, which may become a risk factor for human infection. Furthermore, this study assessed the survival and viability of the bacteria in commercial eggs. The eggs were placed in contact with wood shavings infected with C. jejuni to check the passage of the bacteria. In parallel, the bacteria were inoculated directly into the air chamber to assess the viability in the egg yolk. To determine whether the albumen and egg fertility interferes with the entry and survival of bacteria, we used varying concentrations of albumen and SPF and commercial eggs. C. jejuni was recovered in SPF eggs (fertile after three hours in contact with contaminated wood shavings but not in infertile commercial eggs. The colonies isolated in the SPF eggs were identified by multiplex PCR and the similarity between strains verified by RAPD-PCR. The bacteria grew in different concentrations of albumen in commercial and SPF eggs. We did not find C. jejuni in commercial eggs inoculated directly into the air chamber, but the bacteria were viable during all periods tested in the wood shavings. This study shows that consumption of commercial eggs infected with C. jejuni does not represent a potential risk to human health.

  11. Activities dedicated to FCPP commercialization at Toshiba

    Ikeda, Shin-ichi; Ozono, Jiro; Sato, Nobuaki [Toshiba Corp., Tokyo (Japan)


    The present line-up of fuel cell power plants (FCPPs) at Toshiba consists of 11MW FCPP for pressurized operation, 1000kW on-site FCPP and 200kW on-site FCPP. In these, an 11MW FCPP installed at Goi Power Station of Tokyo Electric Power Company (TEPCO) is providing valuable experience through more than 20,000 cumulative hours of operation. Also, a 1000kW on-site FCPP, which Toshiba manufactured under the joint program of NEDO and PAFC Technology Research Association, has cumulative operation of 7,500 hours. Toshiba, however, believes that the 200kW on-site FCPP is the leader in the commercialization of phosphoric acid FCPP. This paper therefore presents the development status of 200kW power plants and our strategic considerations for full commercialization of PC25 type 200kW FCPP.

  12. Transition of Japanese commercial space: What has been lost from the commercial space?

    Fujioka Tatsuma


    Full Text Available This paper compares the types of two commercial spaces in modern Japan, shopping mall and “traditional” shopping district called Shotengai, from the viewpoint of commercial space as the third space in the city. Particularly in the discourse of commercial spaces in Japan, "shopping district" has been portrayed tied to nostalgia. Therefore, the transition of commercial space is always accompanied by a discourse of the" Lost." However, there is no unified opinion about what's been lost in the process of this transition in fact. In this paper, we extract the social category by considering focus on discourse for both places. As a specific object I use to target the research papers and journal articles in Japan. Because these documents are discussed by distinct main thesis and based on specific data, I adopt these materials. After extraction of social category, through the comparison of the two discourses, I reveal what kind of nature is the "Lost" at the commercial spaces as the third place in the city. I also discuss how this change is related the changes in Japanese social relationship and community.

  15. NASA Solar Array Demonstrates Commercial Potential

    Creech, Gray


    A state-of-the-art solar-panel array demonstration site at NASA's Dryden Flight Research Center provides a unique opportunity for studying the latest in high-efficiency solar photovoltaic cells. This five-kilowatt solar-array site (see Figure 1) is a technology-transfer and commercialization success for NASA. Among the solar cells at this site are cells of a type that was developed in Dryden Flight Research Center s Environmental Research Aircraft and Sensor Technology (ERAST) program for use in NASA s Helios solar-powered airplane. This cell type, now denoted as A-300, has since been transferred to SunPower Corporation of Sunnyvale, California, enabling mass production of the cells for the commercial market. High efficiency separates these advanced cells from typical previously commercially available solar cells: Whereas typical previously commercially available cells are 12 to 15 percent efficient at converting sunlight to electricity, these advanced cells exhibit efficiencies approaching 23 percent. The increase in efficiency is due largely to the routing of electrical connections behind the cells (see Figure 2). This approach to increasing efficiency originated as a solution to the problem of maximizing the degree of utilization of the limited space available atop the wing of the Helios airplane. In retrospect, the solar cells in use at this site could be used on Helios, but the best cells otherwise commercially available could not be so used, because of their lower efficiencies. Historically, solar cells have been fabricated by use of methods that are common in the semiconductor industry. One of these methods includes the use of photolithography to define the rear electrical-contact features - diffusions, contact openings, and fingers. SunPower uses these methods to produce the advanced cells. To reduce fabrication costs, SunPower continues to explore new methods to define the rear electrical-contact features. The equipment at the demonstration site includes

  16. Commercial considerations in tissue engineering.

    Mansbridge, Jonathan


    Tissue engineering is a field with immense promise. Using the example of an early tissue-engineered skin implant, Dermagraft, factors involved in the successful commercial development of devices of this type are explored. Tissue engineering has to strike a balance between tissue culture, which is a resource-intensive activity, and business considerations that are concerned with minimizing cost and maximizing customer convenience. Bioreactor design takes place in a highly regulated environment, so factors to be incorporated into the concept include not only tissue culture considerations but also matters related to asepsis, scaleup, automation and ease of use by the final customer. Dermagraft is an allogeneic tissue. Stasis preservation, in this case cryopreservation, is essential in allogeneic tissue engineering, allowing sterility testing, inventory control and, in the case of Dermagraft, a cellular stress that may be important for hormesis following implantation. Although the use of allogeneic cells provides advantages in manufacturing under suitable conditions, it raises the spectre of immunological rejection. Such rejection has not been experienced with Dermagraft. Possible reasons for this and the vision of further application of allogeneic tissues are important considerations in future tissue-engineered cellular devices. This review illustrates approaches that indicate some of the criteria that may provide a basis for further developments. Marketing is a further requirement for success, which entails understanding of the mechanism of action of the procedure, and is illustrated for Dermagraft. The success of a tissue-engineered product is dependent on many interacting operations, some discussed here, each of which must be performed simultaneously and well.

  19. [Genetic Investigation of bla(CTX-M)-typing in Extended-spectrum β-lactamase-producing Escherichia coli and Klebsiella pneumoniae from Clinical Specimens and Commercially Available Chicken Liver].

    Kan, Miki; Shinomiya, Hiroto; Kitao, Takashi


    A genetic investigation consisting of the bla(CTX-M) typing was performed using 40 extended spectrum β-lactamase (ESBL)-producing Escherichia coli isolates from chicken liver and 43 ESBL-producing E. coli and 42 ESBL-producing Klebsiella pneumoniae isolates from patients. The types were determined using a sequence analysis. In 31 isolates in the bla(CTX-M-1) group, there were 13 with the bla(CTX-M-1) and all were from chicken liver. Nine E. coli isolates from chicken liver and one E. coli isolate from patients were found to be bla(CTX-M-55). In the bla(CTX-M-15), there were 6 E. coli isolates and one K. pneumoniae isolate from patients. All 39 isolates in the bla(CTX-M-2) group had the blac(CTX-M-2). Fifty-five isolates were found in the bla(CTX-M-9) group, the highest detection frequency, with 36 possessing bla(CTX-M-14) : 20 E. coli and 13 K. pneumoniae from patients and 3 E. coli from chicken liver. There were 17 bla(CTX-M-27) isolates, including 10 E. coli and 7 K. pneumoniae from patients. One bla(CTX-M-90) K. pneumoniae isolate and one bla(CTX-M-9) E. coli isolate were also obtained from patients. These results indicate that the E. coli isolates from chicken liver consist of bla(CTX-M-1), bla(CTX-M-2) and bla(CTX-M-55) ; the E. coli isolates from patients consist of bla(CTX-M-14) and bla(CTX-M-27) ; and the K. pneumoniae isolates from patients consist of bla(CTX-M-2), bla(CTX-M-14) and bla(CTX-M-27). Therefore, the bla(CTX-M) type differs in isolates from chicken liver and those from humans. These results suggest that it is unlikely that ESBL-producing E. coli from chicken liver are firmly established in the human intestinal tract.

  6. High-performance commercial building systems

    Selkowitz, Stephen


    This report summarizes key technical accomplishments resulting from the three year PIER-funded R&D program, ''High Performance Commercial Building Systems'' (HPCBS). The program targets the commercial building sector in California, an end-use sector that accounts for about one-third of all California electricity consumption and an even larger fraction of peak demand, at a cost of over $10B/year. Commercial buildings also have a major impact on occupant health, comfort and productivity. Building design and operations practices that influence energy use are deeply engrained in a fragmented, risk-averse industry that is slow to change. Although California's aggressive standards efforts have resulted in new buildings designed to use less energy than those constructed 20 years ago, the actual savings realized are still well below technical and economic potentials. The broad goal of this program is to develop and deploy a set of energy-saving technologies, strategies, and techniques, and improve processes for designing, commissioning, and operating commercial buildings, while improving health, comfort, and performance of occupants, all in a manner consistent with sound economic investment practices. Results are to be broadly applicable to the commercial sector for different building sizes and types, e.g. offices and schools, for different classes of ownership, both public and private, and for owner-occupied as well as speculative buildings. The program aims to facilitate significant electricity use savings in the California commercial sector by 2015, while assuring that these savings are affordable and promote high quality indoor environments. The five linked technical program elements contain 14 projects with 41 distinct R&D tasks. Collectively they form a comprehensive Research, Development, and Demonstration (RD&D) program with the potential to capture large savings in the commercial building sector, providing significant economic benefits to

Nurses' involvement allowed balance between their needs and institution requirements.

  9. Practicing shared decision making in the outpatient psychiatric care of adults with severe mental illnesses: redesigning care for the future.

    Torrey, William C; Drake, Robert E


    Psychiatrist outpatient office visits have the potential to support the recovery of adults with severe mental illnesses by engaging them in a collaborative process of evaluating, selecting, and trying individually-tailored therapeutic options. Evidence-informed shared decision making is difficult for psychiatrists to offer within the framework of care as it is delivered today: it requires time, easy access to relevant scientific information, and extensive communication between patients and psychiatrists. In this paper, we describe the current structural obstacles to collaborative psychiatric care and envision a redesigned office visit process that facilitates active informed patient involvement.

  10. Redesigning healthcare systems to meet the health challenges associated with climate change in the twenty-first century.

    Phua, Kai-Lit


    In the twenty-first century, climate change is emerging as a significant threat to the health and well-being of the public through links to the following: extreme weather events, sea level rise, temperature-related illnesses, air pollution patterns, water security, food security, vector-borne infectious diseases, and mental health effects (as a result of extreme weather events and climate change-induced population displacement). This article discusses how national healthcare systems can be redesigned through changes in its components such as human resources, facilities and technology, health information system, and health policy to meet these challenges.

  11. Return to work outcomes of the Redesigning Daily Occupations (ReDO) program for women with stress-related disorders--a comparative study.

    Eklund, Mona; Erlandsson, Lena-Karin


    Stress-related disorders are a frequent cause for sick leave, with consequences such as great distress and adverse economic effects for the affected person and substantial costs for society. Identifying effective interventions that facilitate return to work is thus important. The aim of this study was to evaluate the effectiveness of the 16-week Redesigning Daily Occupations program as a work rehabilitation method for Swedish women with stress-related disorders. The authors of this study hypothesized that, compared to women who got Care as Usual, 12 months after completed rehabilitation a larger proportion of the Redesigning Daily Occupations women would have returned to work, and they would have less sick leave, perceive less stress, and have greater self-esteem. Forty-two women entered the Redesigning Daily Occupations intervention and a matched comparison group received Care as Usual. The data, collected between 2007 and 2010, consisted of registry information and questionnaires targeting socio-demographics, perceived stress, and self-esteem. The findings partly verified the hypotheses. A larger proportion of the Redesigning Daily Occupations women returned to work and they decreased their sick leave and increased their self-esteem more than the Care as Usual group, but the groups did not differ in stress reduction. Thus, the Redesigning Daily Occupations seems to be a promising work rehabilitation method for women with stress-related disorders.

  12. Plausibility check of a redesigned rain-on-snow simulator (RASA)

    Rössler, Ole; Probst, Sabine; Weingartner, Rolf


    Rain-on-snow events are fascinating but still not completely understood processes. Although, several studies and equations have been published since decades that describe past events and theoretical descriptions, empirical data of what is happening in the snow cover is far less available. A way to fill this gap of empirical data, rain-on-snow-simulators might be of help. In 2013, Juras et al. published their inspiring idea of a portable rain-on-snow simulator. The huge advantage of this devise - in contrast to other purely field-based experiments - are their fixed, and mostly standardized conditions and the possibility to measure all required data to monitor the water fluxes and melting processes at a time. Mounted in a convenient location, a large number of experiments are relatively easy conductible. We applied and further developed the original device and plausified the results of this redesigned version, called RASA. The principal design was borrowed from the original version being a frame with a sprinkler on top and a snow sample in a box at the bottom, from which the outflow is measured with a tipping gauge. We added a moving sprinkling plate to ensure a uniform distribution of raindrops on the snow, and - most importantly - we suspended the watered snow sampled on weighting cells. The latter enables to continuous measurement of the snow sample throughout the experiment and thus the indirect quantification of liquid water saturation, water holding capacity, and snowmelt amount via balance equations. As it is remains unclear if this device is capable to reproduce known processes, a hypothesis based plausibility check was accomplished. Thus, eight hypothesizes were derived from literature and tested in 28 experiments with the RASA mounted at 2000 m elevation. In general, we were able to reproduce most of the hypotheses. The RASA proved to be a very valuable device that can generate suitable results and has the potential to extend the empirical-experimental data

    The Experimental Physics and Industrial Control System (EPICS) is a software toolkit, developed by a worldwide collaboration, which significantly reduces the level of effort required to implement a new control system. Recent developments now also significantly reduce the level of effort required to integrate commercial, legacy and/or site-authored control systems with EPICS. This paper will illustrate with an example both the level and type of effort required to use EPICS with other control system components as well as the benefits that may arise.

  17. Large improvement of phosphorus incorporation efficiency in n-type chemical vapor deposition of diamond

    Ohtani, Ryota; Yamamoto, Takashi; Janssens, Stoffel D.; Yamasaki, Satoshi; Koizumi, Satoshi


    Microwave plasma enhanced chemical vapor deposition is a promising way to generate n-type, e.g., phosphorus-doped, diamond layers for the fabrication of electronic components, which can operate at extreme conditions. However, a deeper understanding of the doping process is lacking and low phosphorus incorporation efficiencies are generally observed. In this work, it is shown that systematically changing the internal design of a non-commercial chemical vapor deposition chamber, used to grow diamond layers, leads to a large increase of the phosphorus doping efficiency in diamond, produced in this device, without compromising its electronic properties. Compared to the initial reactor design, the doping efficiency is about 100 times higher, reaching 10%, and for a very broad doping range, the doping efficiency remains highly constant. It is hypothesized that redesigning the deposition chamber generates a higher flow of active phosphorus species towards the substrate, thereby increasing phosphorus incorporation in diamond and reducing deposition of phosphorus species at reactor walls, which additionally reduces undesirable memory effects.

  18. Commercialization of higher education: characteristics and trends

    M. V. Klyov


    Much attention is given to the variety of approaches to the study of higher education. Today, sociological discourses used to analyze modern innovation in the education sphere, such as multiculturalism, diversification, confessionalization, regionalization, cosmopolitan atmosphere in the modern world, including the global information technology to the higher education. In the course of innovation and modernization of higher education, commercialization becomes significantly prevalent a phenomenon and a social process of educational institutions, which requires considerable research. The review of the US and European models of higher education makes it possible to understand the essence of appearance in the literature of such concepts as «academic capitalism», «university of market­type» and «entrepreneurial University», analyze relation to the appearance of private education and income and define the priority of commercialization. Indisputably, with both positive and negative, as a result of the reform of higher education appeared the peculiar environment of business education, which requires the existence of new rules of interaction, status­role relationships, values and norms . In some extent, commercialization is a transformation of knowledge into a commodity (speaking in the context of consumer society; however, it is the growing influence of market relations on the purpose and objectives of higher education, the growth of the importance of knowledge as a resource for economic development that focuses on  the concept of an economy based on knowledge.

    Biological-mediated conversion of pretreated lignocellulosic biomass to biofuels and biochemicals is a promising avenue towards energy sustainability. However, a critical impediment to the commercialization of cellulosic biofuel production is the high cost of cellulase enzymes needed to deconstruct biomass into fermentable sugars. One major factor driving cost is cellulase adsorption and inactivation in the presence of lignin, yet we currently have a poor understanding of the protein structure-function relationships driving this adsorption. In this work, we have systematically investigated the role of protein surface potential on lignin adsorption using a model monomeric fluorescent protein. We have designed and experimentally characterized 16 model protein variants spanning the physiological range of net charge (-24 to +16 total charges) and total charge density (0.28 to 0.40 charges per sequence length) typical for natural proteins. Protein designs were expressed, purified, and subjected to in silico and in vitro biophysical measurements to evaluate the relationship between protein surface potential and lignin adsorption properties. The designs were comparable to model fluorescent protein in terms of thermostability and heterologous expression yield, although the majority of the designs unexpectedly formed homodimers. Protein adsorption to lignin was studied at two different temperatures using Quartz Crystal Microbalance with Dissipation Monitoring and a subtractive mass balance assay. We found a weak correlation between protein net charge and protein-binding capacity to lignin. No other single characteristic, including apparent melting temperature and 2nd virial coefficient, showed correlation with lignin binding. Analysis of an unrelated cellulase dataset with mutations localized to a family I carbohydrate-binding module showed a similar correlation between net charge and lignin binding capacity. Overall, our study provides strategies to identify highly active

  20. Commercial SNF Accident Release Fractions

    J. Schulz


    The purpose of this analysis is to specify and document the total and respirable fractions for radioactive materials that could be potentially released from an accident at the repository involving commercial spent nuclear fuel (SNF) in a dry environment. The total and respirable release fractions are used to support the preclosure licensing basis for the repository. The total release fraction is defined as the fraction of total commercial SNF assembly inventory, typically expressed as an activity inventory (e.g., curies), of a given radionuclide that is released to the environment from a waste form. Radionuclides are released from the inside of breached fuel rods (or pins) and from the detachment of radioactive material (crud) from the outside surfaces of fuel rods and other components of fuel assemblies. The total release fraction accounts for several mechanisms that tend to retain, retard, or diminish the amount of radionuclides that are available for transport to dose receptors or otherwise can be shown to reduce exposure of receptors to radiological releases. The total release fraction includes a fraction of airborne material that is respirable and could result in inhalation doses; this subset of the total release fraction is referred to as the respirable release fraction. Accidents may involve waste forms characterized as: (1) bare unconfined intact fuel assemblies, (2) confined intact fuel assemblies, or (3) canistered failed commercial SNF. Confined intact commercial SNF assemblies at the repository are contained in shipping casks, canisters, or waste packages. Four categories of failed commercial SNF are identified: (1) mechanically and cladding-penetration damaged commercial SNF, (2) consolidated/reconstituted assemblies, (3) fuel rods, pieces, and debris, and (4) nonfuel components. It is assumed that failed commercial SNF is placed into waste packages with a mesh screen at each end (CRWMS M&O 1999). In contrast to bare unconfined fuel assemblies, the
