    A multi-well microbially enhanced oil recovery field pilot has been performed in the Southeast Vassar Vertz Sand Unit in Payne County, Oklahoma. The primary emphasis of the experiment was preferential plugging of high permeability zones for the purpose of improving waterflood sweep efficiency. Studies were performed to determine reservoir chemistry, ecology, and indigenous bacteria populations. Growth experiments were used to select a nutrient system compatible with the reservoir that encouraged growth of a group of indigenous nitrate-using bacteria and inhibit growth of sulfate-reducing bacteria. A specific field pilot area behind an active line drive waterflood was selected. Surface facilities were designed and installed. Injection protocols of bulk nutrient materials were prepared to facilitate uniform distribution of nutrients within the pilot area. By the end of December, 1991, 82.5 tons (75.0 tonnes) of nutrients had been injected in the field. A tracer test identified significant heterogeneity in the SEVVSU and made it necessary to monitor additional production wells in the field. The tracer tests and changes in production behavior indicate the additional production wells monitored during the field trial were also affected. Eighty two and one half barrels (13.1 m{sup 3}) of tertiary oil have been recovered. Microbial activity has increased CO{sub 2} content as indicated by increased alkalinity. A temporary rise in sulfide concentration was experienced. These indicate an active microbial community was generated in the field by the nutrient injection. Pilot area interwell pressure interference test results showed that significant permeability reduction occurred. The interwell permeabilities in the pilot area between the injector and the three pilot production wells were made more uniform which indicates a successful preferential plugging enhanced oil recovery project.

    1998-01-01

    A piloted simulation study has been conducted in a research simulator to provide a means to estimate the effects of different levels of wake turbulence on final approach. A worst-case methodology was used to ensure conservative estimates. Fourteen airline pilots voluntarily participated in the study and flew almost 1000 approaches. The pilots rated the subjective severity of the disturbances using a special rating scale developed for this study. Several objective measures of the airplane/pilot response to the simulated wake turbulence were also made. All the data showed a large amount of variation between pilots and to a lesser extent for a given pilot. Therefore, the data were presented at 50, 70, 90 percentile levels as a function of vortex strength. The data allow estimates of the vortex strength for a given subjective or objective response and vice versa. The results of this study appear to be more conservative than the results of previous studies.

    Background and Purpose Argatroban is a direct thrombin inhibitor that safely augments recanalization achieved by tPA in animal stroke models. The Argatroban tPA Stroke Study was an open-label, pilot safety study of tPA plus Argatroban in patients with ischemic stroke due to proximal intracranial occlusion. Methods During standard dose IV tPA, a 100μg/kg bolus of Argatroban and infusion for 48 hours was adjusted to a target partial thromboplastin time of 1.75 times baseline. The primary outcome was incidence of significant intracerebral hemorrhage defined as either symptomatic intracerebral hemorrhage (sICH) or parenchymal hemorrhage-type 2 (PH-2). Recanalization was measured at 2 and 24 hours by transcranial Doppler (TCD) or CT angiography. Results Sixty-five patients were enrolled (45% men, mean age 63±14 years, median NIHSS = 13). The median (IQR) time tPA to Argatroban bolus was 51 (38, 60) minutes. Target anticoagulation was reached at a median (IQR) of 3 (2, 7) hours. Significant intracerebral hemorrhage occurred in 4 patients (6.2%, 95% CI 1.7–15.0). Of these, 3 were symptomatic (4.6%, 95% CI 0.9–12.9). Seven patients (10%) died in the first 7 days. Within the 2 hour monitoring period, TCD recanalization (n=47) occurred in 29 (61%) patients: complete in 19 (40%) and partial in another 10 (21%). Conclusion The combination of Argatroban and IV tPA is potentially safe in patients with moderate neurological deficits due to proximal intracranial arterial occlusions, and may produce more complete recanalization than tPA alone. Continued evaluation of this treatment combination is warranted. PMID:22223235

    This project incorporates two related research projects directed toward understanding respiratory carcinogenesis in radon-exposed former uranium miners. The first project involved a continuation of the tissue resource of lung cancer cases from former underground uranium miners and comparison cases from non-miners. The second project was a pilot study for a proposed longitudinal study of respiratory carcinogenesis in former uranium miners. The objectives including facilitating the investigation of molecular changes in radon exposed lung cancer cases, developing methods for prospectively studying clinical, cytologic, cytogenetic, and molecular changes in the multi-event process of respiratory carcinogenesis, and assessing the feasibility of recruiting former uranium miners into a longitudinal study that collected multiple biological specimens. A pilot study was conducted to determine whether blood collection, induced sputum, bronchial brushing, washings, and mucosal biopsies from participants at two of the hospitals could be included efficiently. A questionnaire was developed for the extended study and all protocols for specimen collection and tissue handling were completed. Resource utilization is in progress at ITRI and the methods have been developed to study molecular and cellular changes in exfoliated cells contained in sputum as well as susceptibility factors.

  10. SUPERCRITICAL WATER PARTIAL OXIDATION PHASE I - PILOT-SCALE TESTING / FEASIBILITY STUDIES FINAL REPORT

    2005-01-01

    Under Cooperative Agreement No. DE-FC36-00GO10529 for the Department of Energy, General Atomics (GA) is developing Supercritical Water Partial Oxidation (SWPO) as a means of producing hydrogen from low-grade biomass and other waste feeds. The Phase I Pilot-scale Testing/Feasibility Studies have been successfully completed and the results of that effort are described in this report. The Key potential advantages of the SWPO process is the use of partial oxidation in-situ to rapidly heat the gasification medium, resulting in less char formation and improved hydrogen yield. Another major advantage is that the high-pressure, high-density aqueous environment is ideal for reaching and gasifying organics of all types. The high water content of the medium encourages formation of hydrogen and hydrogen-rich products and is especially compatible with high water content feeds such as biomass materials. The high water content of the medium is also effective for gasification of hydrogen-poor materials such as coal. A versatile pilot plant for exploring gasification in supercritical water has been established at GA's facilities in San Diego. The Phase I testing of the SWPO process with wood and ethanol mixtures demonstrated gasification efficiencies of about 90%, comparable to those found in prior laboratory-scale SCW gasification work carreid out at the University of Hawaii at Manoa (UHM) as well as other biomass gasification experience with conventional gasifiers. As in the prior work at UHM, a significant amount of the hydrogen found in the gas phase products is derived from the water/steam matrix. The studies at UHM utilized an indirectly heated gasifier with an acitvated carbon catalyst. In contrast, the GA studies utilized a directly heated gasifier without catalyst, plus a surrogate waste fuel. Attainment of comparable gasification efficiencies without catalysis is an important advancement for the GA process, and opens the way for efficient hydrogen production from low

    This study is aimed to investigate the understanding of antibiotic use and antibiotic resistance and its correlate factors among final-year medical and pharmacy students at International Islamic University Malaysia (IIUM). This was a cross-sectional study. The study instrument was developed by extensive literature search and was subjected to face validity and content validity to medical and pharmacy academics. A pilot study was conducted to ascertain the reliability coefficient. Data was entered to SPSS version 17 and descriptive and inferential statistics were applied. A total of 123 questionnaires were included in the study. Out of 123 respondents, 58.5% (n = 72) were final-year medical students, while 41.5% (n = 51) were final-year pharmacy students. The majority of the respondents showed adequate knowledge regarding the course contents related to antibiotics (n = 116; 94.3%). Almost all the respondents correctly reported the difference between bactericidal and bacteriostatic antibiotics. Only 15.4% (n = 19) and 27.6% (n = 34) of students were able to recognize Streptococcus pyogenes as non-pencillin resistant bacterium and Enterococcus as vancomycin-resistant bacterium, respectively. The students showed good understanding regarding antibiotic resistance. In comparison to medical students, pharmacy students showed better understanding and more adequate knowledge, as the mean value for each domain was slightly higher for pharmacy students. Extensively improving the curriculum and educating healthcare professionals, especially physicians and pharmacists, right from the time of their educational training can inculcate a moral responsibility toward the judicious use of antibiotics, which can serve to eradicate antibiotic resistance.

    Computer packages have been introduced to simulate the movements of the jaw in three dimensions to facilitate planning of treatment. After final 3-dimensional virtual planning, a rapid prototype wafer can be manufactured and used in theatre. Our aim was to assess the accuracy of rapid prototyping of virtual wafers derived from laser scanned dental models using CAD/CAM software. Upper and lower plaster models from 10 orthognathic patients, the articulated models, and the conventional wafers were scanned. The virtual wafers were made from CAD/CAM software, and printed on a stereolithographic printer. We also scanned the articulated models with rapid prototype wafers in place. The validity of the final rapid prototype wafer was measured by the accuracy with which upper and lower models related to one another. The absolute mean error of the rapid prototype wafer when aligned with the dental models was 0.94 (0.09) mm. The absolute distance of the 2 models articulated by conventional and rapid prototype wafers ranged from 0.04 - 1.73mm. The rapid prototype wafers were able to orientate the upper and lower dental models with an absolute mean error of 0.94 (0.09) mm, but it ranged from 0.04-1.73mm.

    A two-year pilot study was conducted of the Health Physics Society Standards Committee (HPSSC) Standard titled, Criteria for Testing Personnel Dosimetry Performance. The objectives of the pilot study were: to give processors an opportunity to correct any problems that are uncovered; to develop operational and administrative prodedures to be used later by a permanent testing laboratory; and to determine whether the proposed HPSSC Standard provides an adequate and practical test of dosimetry performance. Fifty-nine dosimetry processors volunteered to submit dosimeters for test irradiations according to the requirements of the HPSSC Standard. The feasibility of using the HPSSC Standard for a future mandatory testing program for personnel dosimetry processors is discussed. This report shows the results of the pilot study and contains recommendations for revisions in the Standard that will make a mandatory testing program useful to regulatory agencies, dosimetry processors, and radiation workers that use personnel dosimeters.

    Fischer 344 rats were examined for effects of inhaled nitric acid and ozone on macrophage cell function, to evaluate new endpoints for future acid inhalation studies. Pulmonary macrophage respiratory burst activity, production of arachidonic acid metabolites (leukotriene B4 and leukotriene C4) by macrophages, and lavage fluid elastase inhibitory capacity were found to be affected by in vivo exposure to nitric acid vapor, alone or in combination with ozone. These results have implications with respect to the development of lung infections, asthma, and emphysema.

    The study characterizes contamination in edible fish and shellfish from Galveston Bay. The sampling design called for the analysis of trace contaminants in five species from four sites in Galveston Bay. The goal of the sampling program was to collect ten specimens of each target organism that were of legal market size from each collection site. Standard fisheries data were recorded for all collections. The analytical program called for the analyses of 10 individual specimens of the target organisms from each site (200 edible tissue (muscle) samples). Fifty (50) liver samples were composed for analysis from the 120 fishes. The trace contaminants that were measured included heavy metals, polynuclear aromatic hydrocarbons (PAH's), pesticides and PCBs and a GC-MS scan for other EPA organic priority pollutants. In general, trace contaminants were higher in oyster and crab tissues than fish tissue.

    Simulation-based medical education has rapidly evolved over the past two decades, despite this, there are few published reports of its use in critical care teaching. We hypothesised that simulation-based teaching of a critical care topic to final-year medical students is superior to lecture-based teaching. Thirty-nine final-year medical students were randomly assigned to either simulation-based or lecture-based teaching in the chosen critical care topic. The study was conducted over a 6-week period. Efficacy of each teaching method was compared through use of multiple choice questionnaires (MCQ) - baseline, post-teaching and 2 week follow-up. Student satisfaction was evaluated by means of a questionnaire. Feasibility and resource requirements were documented by teachers. Eighteen students were randomised to simulation-based, and 21 to lecture-based teaching. There were no differences in age and gender between groups (p > 0.05). Simulation proved more resource intensive requiring specialised equipment, two instructors, and increased duration of teaching sessions (126.7 min (SD = 4.71) vs 68.3 min (SD = 2.36)). Students ranked simulation-based teaching higher with regard to enjoyment (p = 0.0044), interest (p = 0.0068), relevance to taught subject (p = 0.0313), ease of understanding (p = 0.0476) and accessibility to posing questions (p = 0.001). Both groups demonstrated improvement in post-teaching MCQ from baseline (p = 0.0002), with greater improvement seen among the simulation group (p = 0.0387), however, baseline scores were higher among the lecture group. The results of the 2-week follow-up MCQ and post-teaching MCQ were not statistically significant when each modality were compared. Simulation was perceived as more enjoyable by students. Although there was a greater improvement in post-teaching MCQ among the simulator group, baseline scores were higher among lecture group which limits interpretation of efficacy

    1989-07-01

    Atropine is fielded as an antidote for organophosphate poisoning where chemical nerve agents are used. However, inappropriate self-injection may lead to anticholinergic side effects detrimental to aviators in flight. To determine the scope and magnitude of these possible side effects, 12 male Army helicopter pilots in good health flew several missions in a helicopter simulator after being injected (I.M.) with either a placebo or 2mg or 4mg of atropine sulfate. Physiological effects essentially followed the classical model. The 2 mg dose of atropine caused small degradations on some of laboratory-collected measures, but often did not produce effects, which differed significantly from those produced by a placebo dose. A 4mg dose of atropine, however, exerted a variety of statistically significant effects upon flight performance, contrast sensitivity, cognitive performance, tracking accuracy, and cortical evoked responses. The flight performance evaluations (both subjective and objective) showed statistically significant changes in the subject's abilities to fly the simulator. Results obtained from other tasks in the study suggest, further, the decrements in flight performance resulted from a slowing of both information processing and psychomotor performance. Atropine effects were not of sufficient magnitude to preclude further research under actual flight conditions.

    1993-01-01

    An interdisciplinary research team of engineers, geologists, and computer scientists was assembled at LSU to develop unproved methods for prospecting for bypassed oil and to support oil and gas producers in Louisiana. The overall objective of the project was to develop methods for extending the producing life of several types of reservoirs by reducing the amount of oil being bypassed and abandoned. As part of this work, the team collected information available from public sources for several example reservoirs. One task of the project was to develop a format for the compilation of the extensive but cumbersome Louisiana reservoir data so that it could be used by government and industry to evaluate the resource and plan future activities. The existing information system maintained by Louisiana is a Production Audit Reporting System (PARS). It was designed to allow auditing of oil and gas production and severance taxes associated with this production. It was not intended to be used as a database for determining reservoir recovery efficiency or prospecting for oil and gas. Its use for these purposes, however, has been increasing. The database format suggested in this report would allow production information to be easily displayed by reservoir as well as by lease, unit, or well. The data collected as part of the bypassed-oil study was used to illustrate the proposed new format. This pilot database, or atlas, contains information available for 15 reservoirs. It is recommended that LSU continue to compile and publish database information on the potential for bypassed oil in Louisiana`s active reservoirs. This technology-transfer activity should focus each year on those active reservoirs involved in hearings of the Louisiana Office of Conservation. It should also focus on reservoirs being screened by LSU for EOR.

    A multi-well microbially enhanced oil recovery field pilot has been performed in the Southeast Vassar Vertz Sand Unit in Payne County, Oklahoma. The primary emphasis of the experiment was preferential plugging of high permeability zones for the purpose of improving waterflood sweep efficiency. Studies were performed to determine reservoir chemistry, ecology, and indigenous bacteria populations. Growth experiments were used to select a nutrient system compatible with the reservoir that encouraged growth of a group of indigenous nitrate-using bacteria and inhibit growth of sulfate-reducing bacteria. A specific field pilot area behind an active line drive waterflood was selected. Surface facilities were designed and installed. Injection protocols of bulk nutrient materials were prepared to facilitate uniform distribution of nutrients within the pilot area. By the end of December, 1991, 82.5 tons (75.0 tonnes) of nutrients had been injected in the field. A tracer test identified significant heterogeneity in the SEVVSU and made it necessary to monitor additional production wells in the field. The tracer tests and changes in production behavior indicate the additional production wells monitored during the field trial were also affected. Eighty two and one half barrels (13.1 m[sup 3]) of tertiary oil have been recovered. Microbial activity has increased CO[sub 2] content as indicated by increased alkalinity. A temporary rise in sulfide concentration was experienced. These indicate an active microbial community was generated in the field by the nutrient injection. Pilot area interwell pressure interference test results showed that significant permeability reduction occurred. The interwell permeabilities in the pilot area between the injector and the three pilot production wells were made more uniform which indicates a successful preferential plugging enhanced oil recovery project.

    The main body of the report consists of four parts: 1. additives to change process chemistry for SO{sub 2} absorption by Ca(OH){sub 2} slurry; 2. recycle tests and hydration of fly ash with Ca(OH){sub 2} to increase reactivity; 3. limestone as an alternative sorbent and additive effects; 4. physical and chemical model developments for some of the additive effects and spray dryer mathematical model application. As the concentration of SO{sub 2} in the flue gases increases, the SO{sub 2} removal efficiency will go down. Additives such as delinquent salts (NaOH, NaCl, and NaHCO{sub 3}) have been shown to improve SO{sub 2} uptake, and these additive tests have indicated that SO{sub 2} uptake may be increased by as much as 60% over baseline conditions. Other additives such as H{sub 2}O{sub 2}, sugar, and some organic acids which can change the chemical reaction processes are suggested and tested, and some promising results have been obtained. Recycle has been shown to increase sorbent utilization by allowing partially reacted sorbent to react further with the SO{sub 2} in the flue gases. Two types of Ohio coal fly ashes have been extensively studied, and improvement of utilization in spray dryer flue gas desulfurization has been demonstrated. Limestone represents an area where significant cost savings can be realized. The spray dryer tests were designed to provide some results for understanding the magnitude of the limestone performance in the spray dryer system and the additive effects. The additive effects on increasing SO{sub 2} absorption by Ca(OH){sub 2} slurry were investigated, and the chemical and physical properties of these tested additives were studied. Some models have been formed to explain the additive phenomena.

    The objective of this project is to perform a microbial enhanced oil recovery field pilot test in the Southeast Vassar Vertz Sand Unit (SEVVSU) in Payne County, Oklahoma. Indigenous, anaerobic, nitrate-reducing bacteria will be stimulated to selectively plug flow paths which have been preferentially swept by a prior waterflood. This will force future flood water to invade bypassed regions of the reservoir and increase sweep efficiency. During this quarter an additional tracer study was performed in the field to determine pre-treatment flow paths and the first nutrients were injected. 2 figs.

    This report covers progress made during the first year of the Microbial Field Pilot Study project. Information on reservoir ecology and characterization, facility and treatment design, core experiments, bacterial mobility, and mathematical modeling are addressed. To facilitate an understanding of the ecology of the target reservoir analyses of the fluids which support bacteriological growth and the microbiology of the reservoir were performed. A preliminary design of facilities for the operation of the field pilot test was prepared. In addition, procedures for facilities installation and for injection treatments are described. The Southeast Vassar Vertz Sand Unit (SEVVSU), the site of the proposed field pilot study, is described physically, historically, and geologically. The fields current status is presented and the ongoing reservoir simulation is discussed. Core flood experiments conducted during the last year were used to help define possible mechanisms involved in microbial enhanced oil recovery. Two possible mechanisms, relative permeability effects and changes in the capillary number, are discussed and related to four Berea core experiments' results. The experiments were conducted at reservoir temperature using SEVVSU oil, brine, and bacteria. The movement and activity of bacteria in porous media were investigated by monitoring the growth of bacteria in sandpack cores under no flow conditions. The rate of bacteria advancement through the cores was determined. A mathematical model of the MEOR process has been developed. The model is a three phase, seven species, one dimensional model. Finite difference methods are used for solution. Advection terms in balance equations are represented with a third- order upwind differencing scheme to reduce numerical dispersion and oscillations. The model is applied to a batch fermentation example. 52 refs., 26 figs., 21 tabs.

    The objective of this project is to perform a microbial enhanced oil recovery field pilot in the Southeast Vassar Vertz Sand Unit (SEVVSU) in Payne County, Oklahoma. Indigenous, anaerobic, nitrate reducing bacteria will be stimulated to selectively plug flow paths which have been referentially swept by a prior waterflood. This will force future flood water to invade bypassed regions of the reservoir and increase sweep efficiency. This report covers progress made during the second year, January 1, 1990 to December 31, 1990, of the Microbial Field Pilot Study project. Information on reservoir ecology, surface facilities design, operation of the unit, core experiments, modeling of microbial processes, and reservoir characterization and simulation are presented in the report. To better understand the ecology of the target reservoir, additional analyses of the fluids which support bacteriological growth and the microbiology of the reservoir were performed. The results of the produced and injected water analysis show increasing sulfide concentrations with respect to time. In March of 1990 Mesa Limited Partnership sold their interest in the SEVVSU to Sullivan and Company. In April, Sullivan and Company assumed operation of the field. The facilities for the field operation of the pilot were refined and implementation was begun. Core flood experiments conducted during the last year were used to help define possible mechanisms involved in microbial enhanced oil recovery. The experiments were performed at SEVVSU temperature using fluids and inoculum from the unit. The model described in last year`s report was further validated using results from a core flood experiment. The model was able to simulate the results of one of the core flood experiments with good quality.

    The Field Test study is currently in full swing, preceded by the successful completion of the Pilot Field Test study that paved the way for collecting data on the astronauts in the medical tent in Kazakhstan. Abigail Sherriff worked alongside Logan Dobbe on one Field Test aspect to determine foot clearance over obstacles (5cm, 10cm, and 15cm) using APDM Inc. Internal Measurement Units (IMU) worn by the astronauts. They created a program to accurately calculate foot clearance using the accelerometer, magnetometer, and gyroscope data with the IMUs attached to the top of the shoes. To validate the functionality of their program, they completed a successful study on test subjects performing various tasks in an optical motion studio, considered a gold standard in biomechanics research. Future work will include further validation and expanding the program to include other analyses.

    A pilot exposure study was undertaken in communities surrounding Rocky Mountain Arsenal (RMA) in order to determine whether exposures to several chemicals were greater among persons who resided there than among residents of a comparison area. In Part II of the exposure study, participants were screened for four organochlorine pesticides (dieldrin, endrin, aldrin, and isodrin): and diisopropylmethylphosphonate (DIMP), and byproduct of nerve agent manufacture, which was producted at RMA by the the United States Army. Urine samples were also screen for chlorophenyl-methylsulfone (CPMSO2), and oxidation product of chlorophenyl-methylsulfide (CPMS). CPMS is an intermediate in the synthesis of nitralin, a herbicide once manufactured at the RMA.

    This pilot study compares the performance of participants in analyzing gas mixtures of nitrogen dioxide in nitrogen by comparison with in-house gravimetric standards using Fourier transformed infrared spectroscopy (FT-IR). In this study the same gas mixtures were used as in the key comparison CCQM-K74, which was designed to evaluate the level of comparability of National Metrology Institutes' measurement capabilities for nitrogen dioxide (NO2) at a nominal mole fraction of 10 µmol/mol. In the comparison CCQM-K74 most of the participants used chemiluminescence, with a small number using UV absorption or FT-IR spectroscopy, and thus it is of interest to improve understanding of the comparative performance of these techniques because they do not exhibit any cross-sensitivity to nitric acid (HNO3), which was known to be present in the mixtures used for the comparison. The results of this pilot study indicate good consistency and a level of agreement similar to that reported in the comparison CCQM-K74, demonstrating that FT-IR can be operated as a comparison method when calibrated with appropriate gas standards and can achieve similar measurement uncertainties to chemiluminescence and UV absorption techniques. An additional pilot study, CCQM-P110-B2, was conducted on the same gas mixtures in parallel with this pilot study. The second study addressed FT-IR spectroscopy when used to measure the gas mixtures with respect to reference spectra. The results of this second study will be reported elsewhere. Main text.

The streams created in Campaign I were used for Campaign II, and during Campaign II more of the same recycle streams were produced, with the addition of recycle streams created during the pilot-scale ion exchange unit operation (Duignan et al., 2004b or Appendix I-2). Campaign III used the recycles from Campaign II and was the first campaign to use all the recycle streams (Duignan et al., 2004c or Appendix I-3). The operation of each of the subsequent campaigns, i.e., II, III, and IV, while different from Campaign I, are very similar to each other, and can be best understood as the process of operating a series of Pretreatment Unit Operations in a somewhat prototypic manner. That is, while Campaign I studied the operation of a single, albeit important, Pretreatment Unit Operation, i.e., Ultrafiltration, subsequent campaigns were to study the four major unit operations that make-up the RPP-WTP Pretreatment Facility. They are: Waste Feed Evaporation Process (FEP), Ultrafiltration Process (UFP), Cesium Ion Exchange Process (CIX), and the Treated LAW Evaporation Process (TLP). Each of the campaigns operated basically as a separate subtask, but as with Campaign I, the recycle streams produced in one campaign were fed into the subsequent campaign. Therefore, all four campaigns were chemically connected through these recycle streams, which carry over effects of the preceding campaign. The results of Campaign IV operations are the subject of this fourth and final report. Separate reports were issued after each of the previous campaigns, but they were treated as interim because of being limited to the results obtained from a single campaign (or past campaigns) and further limited to only highlights of that single campaign. This final report not only discusses the Campaign IV results but compares those with the previous campaigns. Also included is a more comprehensive discussion of the

    This document represents the final report for the Admiralty Inlet Pilot Tidal Project, located in Puget Sound, Washington, United States. The Project purpose was to license, permit, and install a grid-connected deep-water tidal turbine array (two turbines) to be used as a platform to gather operational and environmental data on tidal energy generation. The data could then be used to better inform the viability of commercial tidal energy generation from technical, economic, social, and environmental standpoints. This data would serve as a critical step towards the responsible advancement of commercial scale tidal energy in the United States and around the world. In late 2014, Project activities were discontinued due to escalating costs, and the DOE award was terminated in early 2015. Permitting, licensing, and engineering design activities were completed under this award. Final design, deployment, operation, and monitoring were not completed. This report discusses the results and accomplishments achieved under the subject award.

    Planning a well-designed research study can be tedious and laborious work. However, this process is critical and ultimately can produce valid, reliable study findings. Designing a large-scale randomized, controlled trial (RCT)-the gold standard in quantitative research-can be even more challenging. Even the most well-planned study potentially can result in issues with research procedures and design, such as recruitment, retention, or methodology. One strategy that may facilitate sound study design is the completion of a pilot or feasibility study prior to the initiation of a larger-scale trial. This article will discuss pilot and feasibility studies, their advantages and disadvantages, and implications for oncology nursing research.

    Researchers working with partners in home care to plan a pragmatic multicenter community-based, randomized, controlled trial for leg ulcer compression treatment realized a smaller pilot study would be necessary. Because no framework for conducting pilot studies could be found, the authors developed a framework for pilot study methodology to inform the planning of such research. To this end, an integrative literature review was conducted, guided by an explicit search strategy, retrieval procedures, and appraisal process, to identify recognized pilot study aims, processes, and methodologies used in previously reported community pilot studies. Factors influencing study inclusion were recognized pilot study aims and purposes and a concise working definition of pilot study. Methodologies used in previously conducted community pilot studies were reviewed. Although relevant published research was limited, 11 pilot studies met the inclusion criteria for this review and contained suggestions to further develop or improve plans for larger definitive trials to enable a better fit of protocols within the delivery systems and scopes of practice. Pilot research processes could be divided into two stages: early planning and pilot trial. Direction for procedures and methods was gained relative to planning for an effective pilot study regarding eligibility, recruitment and data collection, management, and analysis. The results were used to develop an organizing framework for the authors' pilot study and named the Pilot Research Process (PReP) Framework. The process was instrumental in working with the authors' research team and clinical partners in the planning of their leg ulcer treatment pilot study. This framework may provide a foundation for others to analyze or develop a pilot study methodology in planning a large-scale study.

    Background This prospective pilot single-institution study was undertaken to document the feasibility, safety, and efficacy of radioembolization of liver-dominant metastatic gastrointestinal cancer using 90Y glass microspheres. Methods Between June 2010 and October 2013, 42 adult patients (26 men, 16 women; median age 60 years) with metastatic chemotherapy-refractory unresectable colorectal (n=21), neuroendocrine (n=11), intrahepatic bile duct (n=7), pancreas (n=2), and esophageal (n=1) carcinomas underwent 60 lobar or segmental administrations of 90Y glass microspheres. Data regarding clinical and laboratory adverse events (AE) were collected prospectively for up to 5.5 years after radioembolization. Radiographic responses were evaluated using Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. Time to maximum response, response duration, progression-free survival (PFS) (hepatic and extrahepatic), and overall survival (OS) were measured. Results Median target dose and activity were 109.4 Gy and 2.6 GBq per treatment session, respectively. Majority of clinical AE were grade 1 or 2 in severity. Patients with colorectal cancer had hepatic objective response rate (ORR) of 25% and a hepatic disease control rate (DCR) of 80%. Median PFS and OS were 1.0 and 4.4 months, respectively. Patients with neuroendocrine tumors (NET) had hepatic ORR and DCR of 73% and 100%, respectively. Median PFS was 8.9 months for this cohort. DCR and median PFS and OS for patients with cholangiocarcinoma were 86%, 1.1 months, and 6.7 months, respectively. Conclusions 90Y glass microspheres device has a favorable safety profile, and achieved prolonged disease control of hepatic tumor burden in a subset of patients, including all patients enrolled in the neuroendocrine cohort.

    Unicompartmental knee arthroplasty (UKA) is an established method of treating isolated gonartrosis. Modern techniques such as computer-assisted surgery (CAS) and minimally invasive surgery (MIS) are attractive complementary methods to UKA. However, the positioning of the components remains a concern. Thus, we performed a prospective study to assess whether there was deviation between the navigated implant position and the final implant position. We performed UKA with MIS and CAS in 13 patients. By comparing intraoperative navigation data with postoperative computed tomography (CT) measurements, we calculated the deviation between the computer-assisted implant position and the final 3-D implant position of the femoral and tibial components. The computer-assisted placement of the femoral and tibial component showed adequate position and consistent results regarding flexion-extension and varus-valgus. However, regarding rotation there was a large variation and 6 of 10 patients were outside the target range for both the femoral component and the tibial component. Difficulties in assessing anatomical landmarks with the CAS in combination with MIS might be a reason for the poor rotational alignment of the components.

    2016-01-01

    Currently on the International Space Station (ISS) and other space vehicles Caution & Warning (C&W) alerts are represented with various auditory tones that correspond to the type of event. This system relies on the crew's ability to remember what each tone represents in a high stress, high workload environment when responding to the alert. Furthermore, crew receive a year or more in advance of the mission that makes remembering the semantic meaning of the alerts more difficult. The current system works for missions conducted close to Earth where ground operators can assist as needed. On long duration missions, however, they will need to work off-nominal events autonomously. There is evidence that speech alarms may be easier and faster to recognize, especially during an off-nominal event. The Information Presentation Directed Research Project (FY07-FY09) funded by the Human Research Program included several studies investigating C&W alerts. The studies evaluated tone alerts currently in use with NASA flight deck displays along with candidate speech alerts. A follow-on study used four types of speech alerts to investigate how quickly various types of auditory alerts with and without a speech component - either at the beginning or at the end of the tone - can be identified. Even though crew were familiar with the tone alert from training or direct mission experience, alerts starting with a speech component were identified faster than alerts starting with a tone. The current study replicated the results from the previous study in a more rigorous experimental design to determine if the candidate speech alarms are ready for transition to operations or if more research is needed. Four types of alarms (caution, warning, fire, and depressurization) were presented to participants in both tone and speech formats in laboratory settings and later in the Human Exploration Research Analog (HERA). In the laboratory study, the alerts were presented by software and participants were

Tsunami inundation maps that provide 100-year and 500-year probabilistic tsunami wave height contours for the Seaside-Gearhart, Oregon, region were developed as part of an interagency Tsunami Pilot Study(1). These maps provided the probability of the tsunami hazard. The next step in determining risk is to determine the vulnerability or degree of loss resulting from the occurrence of tsunamis due to exposure and fragility. The tsunami vulnerability assessment methodology used in this study was developed by M. Papathoma and others(2). This model incorporates multiple factors (e.g. parameters related to the natural and built environments and socio-demographics) that contribute to tsunami vulnerability. Data provided with FEMA's HAZUS loss estimation software and Clatsop County, Oregon, tax assessment data were used as input to the model. The results, presented within a geographic information system, reveal the percentage of buildings in need of reinforcement and the population density in different inundation depth zones. These results can be used for tsunami mitigation, local planning, and for determining post-tsunami disaster response by emergency services.

    The results of the first pilot study designed to evaluate the level of comparability of measurements of nitrogen dioxide (NO2) mole fractions in nitrogen based on measurement procedures that rely on FT-IR spectroscopy as an absolute method of quantification with the traceability of measurement results to line strength data are reported. Participants were required to report measurement results using FT-IR for the gas standard (nominal mole fraction of 10 µmol/mol NO2 in nitrogen) received from the BIPM as part of the CCQM-K74 exercise. In addition, they were required to provide infrared spectra and instrument parameter information to enable a recalculation of their results by the BIPM's, using only its own synthetic spectra calibration procedure with values traceable to the line parameters contained in HITRAN 2004. The relative standard uncertainties based on FT-IR measurements reported by participating laboratories ranged from 0.6% to 4.3%. The relative standard uncertainty of the reference value for each gas standard was 0.4%, as determined during the CCQM-K74 exercise. Of the ten results submitted, only five agreed with the reference value within their expanded uncertainties. Furthermore, major contributions to the uncertainty of FT-IR measurements arose from the optical path length measurements and the uncertainty that could be attributed to line strength data from the HITRAN molecular database. The inclusion of these uncertainty contributions was estimated by the BIPM to result in achievable relative standard uncertainties of 3.4% for its FT-IR measurements using synthetic spectra calibration procedures. Finally the recalculation of the participants' results by the BIPM using the laboratories' submitted experimental characteristics and infrared spectra showed good agreement with the submitted results, indicating that the calculation algorithms were not in themselves a major reason for the spread of results.

    2012-10-01

    It has long been believed that airline pilots are healthier than the general population. There are a number of reasons why this should be the case. However, there is very little evidence to support this belief as fact. This study investigates the health of the pilot population of an Oceanic based airline compared to the health of the general population. Pilots who conducted their medical certificate renewal at the airline's medical unit between 1 November 2009 and 31 October 2010 were included. A medical questionnaire was completed by each pilot at the time of their medical certificate renewal. Data from the questionnaire was entered into a database as well as the pilot's BMI, blood pressure, lipid profile, and blood glucose level. The comparison population was the population who completed the New Zealand Health Survey (NZHS) between 2006-2007. Demographic, lifestyle characteristics, and health status data from the pilots was compared to the NZHS using a Chi-squared test. Included in the study were 595 pilots. With respect to most medical conditions, pilots had a lower prevalence when compared to the general population. Pilots had a higher prevalence of kidney disease (3.3% vs 0.6%) and melanoma skin cancer (19 per 1000 vs 0.4 per 1000). This study suggests that pilots in New Zealand are healthier than the general population with respect to most medical conditions. The two medical conditions that were identified as being overrepresented in pilots may be the result of the occupational environment.

    A wet combustion pilot within the Paris Valley Field, Monterey County, California was initiated in January, 1975 in order to determine the technical and economic feasibility of this enhanced recovery process within a sandstone reservoir having a very viscous crude. Cyclic steaming was also performed and evaluated. Due to the low oil production rates, which were not capable of offsetting the high operating costs, the pilot was terminated during March, 1979. Eighteen producing wells, five air injectors, and one water disposal well were drilled. Primary oil production averaged less than 3 BOPD per well and initial water production ranged from 30 to 100 BWPD per well. Cumulative oil produced during the pilot was 120,623 STBO. Over 90% of the oil produced was due to response from cyclic steaming.

    This paper summarizes three related pilot projects designed to focus on the possible effects of classroom acoustics on fine auditory discrimination as it relates to language acquisition, especially English as a second language. The first study investigated the influence of improving the signal-to-noise ratio on the differentiation of English phonemes. The results showed better differentiation with better signal-to-noise ratio. The second studied speech perception in noise by young adults for whom English was a second language. The outcome indicated that the second language learners required a better signal-to-noise ratio to perform equally to the native language participants. The last study surveyed the acoustic conditions of preschool and day care classrooms, wherein first and second language learning occurs. The survey suggested an unfavorable acoustic environment for language learning.

    The Weeks Island ''S'' sand Reservoir B (''S'' RB) gravity-stable CO2 field test was completed during February 1988. Injection started in October 1978 and production began in January 1981 in this high-permeability, steeply-dipping sandstone reservoir. About 264,000 barrels of oil or 65 percent of the starting volume has been recovered. A 24-percent pore-volume slug of CO2 mixed with about six mole percent of natural gas (mostly methane) was injected at the start of the pilot. Since 1983, produced CO2 plus hydrocarbon gases have been recycled. CO2 usage statistics are 9.34 MCF/BO with recycle and 3.24 MCF/BO based on purchased CO2. Previous annual reports document the pilot design, implementation, and early results for the 1977 to June 1981 time period. This report is a review of early pilot history and a more detailed account of the post June 1981 results and overall interpretation. A reservoir-simulation history match of pilot performance plus core and log data from a 1983 swept-zone evaluation well are described in this report. A brief description of the production facility and an account of the corrosion control program are also included. 11 refs., 34 figs.

    The objective of this study is to demonstrate the feasibility of estimating cumulative exposure of individuals to low concentrations of radon by measuring the amount of Pb-A-10 in their skeletons. This report presents progress to date establishing the validity of an vivo technique to measure skeletal burdens of Pb-210, accumulated from exposure to radon and radon progeny. With the skeletal content of Pb--210 and a model for Pb metabolism, cumulative exposure to radon and its short-lived daughters (radon/daughters) may be calculated for use in deriving a dose-response relationship between lung cancer and exposure to radon/daughters. Data are presented for 29 subjects exposed to ``above-average`` radon concentrations in their homes, showing the correlation between measured Pb--210 burdens, and measured pCi/l and WLM exposure estimates. Their results are compared to measurements of a population of 24 subject`s presumed exposed to average concentrations. Measurements of a Pennsylvania family exposed for a year in a home with an extremely high radon content are also presented. Update of results of an ongoing study of the biological half-time of Pb--210 in man involving measurements, of a retired radiation worker with a 40 year old skeletal burden of Pb-210.

    2004-10-15

    LERs consist of a one page standard form with a standard header and free text data, followed by additional continuation pages of free text data. Currently this LER data is analyzed by first inputting the heading and text data manually into a categorical relational database. The data is then evaluated by enumeration of data in various categories and supplemented by review of individual LERs. This is labor intensive and makes it difficult to relate specific descriptive text to enumerated results. State of the art data mining and visualization technology exists that can eliminate the need for manual categorization, maintain the text relationships within each report, produce the same enumerated results currently available, and provide a tool to support potentially useful additional analysis of the informational content of LERs in a more timely and cost effective manner.

    Thermal destruction of wastes by direct incineration or by cofiring with conventional fuels in boilers, furnaces, or kilns is one of the most-effective methods currently available for disposal of hazardous organic material. However, more information is needed on the potential for emissions to the environment during thermal destruction. The specific objectives of the current study were to identify which of several boiler operational parameters have a major impact on boiler destruction and removal efficiency; and to evaluate and if practical, establish a mathematical model for predicting an upper limit on the amount of cofired waste that could be emitted. The program was carried out in three phases: a detailed characterization of thermal history and environment of a pilot-scale furnace under various sets of operating conditions; a study of the DRE of one compound as conditions were varied; and finally, a study of DRE's of several compounds burned simultaneously (a composite soup).

    BPA has decided to acquire 20 average megawatts (aMW) of electrical power from a privately-owned geothermal power plant on the west flank of Newberry Volcano in Deschutes County, Oregon. The Newberry Project will generate 30 aMW and will be developed, owned, and operated by CE Newberry, Inc. of Portland, Oregon. In addition, BPA has decided to grant billing credits to EWEB for 10 aMW of electrical power and to provide wheeling services to EWEB for the transmission of this power to their system. BPA expects the Newberry Project to be in commercial operation by November 1997. BPA has statutory responsibilities to supply electrical power to its utility industrial and other customers in the Pacific Northwest. The Newberry Project will be used to meet the electrical power supply obligations of these customers. The Newberry Project will also demonstrate the availability of geothermal power to meet power supply needs in the Pacific Northwest and is expected to be the first commercial geothermal plant in the region. The Newberry Project was selected under the BPA Geothermal Pilot Project Program. The goal of the Program is to initiate development of the Pacific Northwest`s large, but essentially untapped, geothermal resources, and to confirm the availability of this resource to meet the energy needs of the region. The primary underlying objective of this Program is to assure the supply of alternative sources of electrical power to help meet growing regional power demands and needs.

    To conduct their work, U.S. Department of Energy (DOE) researchers require access to a wide range of computing systems and information resources outside of their respective laboratories. Electronically communicating with peers using the global Internet has become a necessity to effective collaboration with university, industrial, and other government partners. DOE`s Energy Sciences Network (ESnet) needs to be engineered to facilitate this {open_quotes}collaboratory{close_quotes} while ensuring the protection of government computing resources from unauthorized use. Sensitive information and intellectual properties must be protected from unauthorized disclosure, modification, or destruction. In August 1993, DOE funded four ESnet sites (Argonne National Laboratory, Lawrence Livermore National Laboratory, the National Energy Research Supercomputer Center, and Pacific Northwest Laboratory) to begin implementing and evaluating authenticated ESnet services using the advanced Kerberos Version 5. The purpose of this project was to identify, understand, and resolve the technical, procedural, cultural, and policy issues surrounding peer-to-peer authentication in an inter-organization internet. The investigators have concluded that, with certain conditions, Kerberos Version 5 is a suitable technology to enable ESnet users to freely share resources and information without compromising the integrity of their systems and data. The pilot project has demonstrated that Kerberos Version 5 is capable of supporting trusted third-party authentication across an inter-organization internet and that Kerberos Version 5 would be practical to implement across the ESnet community within the U.S. The investigators made several modifications to the Kerberos Version 5 system that are necessary for operation in the current Internet environment and have documented other technical shortcomings that must be addressed before large-scale deployment is attempted.

    In accordance with the National Environmental Policy Act (NEPA) of 1969, the US Department of Energy (DOE) has prepared this document as environmental input to future decisions regarding the Waste Isolation Pilot Plant (WIPP), which would include the disposal of transuranic waste, as currently authorized. The alternatives covered in this document are the following: (1) Continue storing transuranic (TRU) waste at the Idaho National Engineering Laboratory (INEL) as it is now or with improved confinement. (2) Proceed with WIPP at the Los Medanos site in southeastern New Mexico, as currently authorized. (3) Dispose of TRU waste in the first available repository for high-level waste. The Los Medanos site would be investigated for its potential suitability as a candidate site. This is administration policy and is the alternative preferred by the DOE. (4) Delay the WIPP to allow other candidate sites to be evaluated for TRU-waste disposal. This environmental impact statement is arranged in the following manner: Chapter 1 is an overall summary of the analysis contained in the document. Chapters 2 and 4 set forth the objectives of the national waste-management program and analyze the full spectrum of reasonable alternatives for meeting these objectives, including the WIPP. Chapter 5 presents the interim waste-acceptance criteria and waste-form alternatives for the WIPP. Chapters 6 through 13 provide a detailed description and environmental analysis of the WIPP repository and its site. Chapter 14 describes the permits and approvals necessary for the WIPP and the interactions that have taken place with Federal, State, and local authorities, and with the general public in connection with the repository. Chapter 15 analyzes the many comments received on the DEIS and tells what has been done in this FEIS in response. The appendices contain data and discussions in support of the material in the text.

    The demonstration of the IGRS approach conducted at SWMU 143 on the White Sands Missile Range has provided information needed to complete a technical performance assessment and cost analysis of the technology. At least 70% of the Cr(VI) present in contaminated sediment at the site was reduced, thus verifying the effectiveness of the approach. Most of the treatment occurred in a zone located from {approximately}4 to 10 ft below ground surface, which appears to be a higher permeability interval. A deeper zone from {approximately}10 to 16 ft that contains lower levels of contamination was essentially unaffected. The deeper zone is somewhat finer grained and has a higher clay content and is, thus, less permeable. It appears that most of the treatment gas was channeled through the higher, more-permeable zone and the lower zone was bypassed. Treatment of the lower zone could probably be accomplished, however, if a second injection well were installed and screened across the zone so that treatment gas could be forced into this interval. The amount of H{sub 2}S consumed during the test exceeded the amount predicted by the laboratory treatability study. In addition, the levels of H{sub 2}S observed at the extraction wells were relatively low, even though a significant level of treatment was observed at the site. It is inferred that interfering reactions or slower reaction kinetics are the likely source of consumption of extra H{sub 2}S observed in the field. Future laboratory work will be undertaken to investigate the nature of these chemical reactions and the reaction rates associated with the gaseous reduction of Cr(VI) in soils. Elucidation of these effects may reveal methods for improving the effectiveness of the technology and reducing unit costs. A life-cycle cost model was developed for the technology based on demonstration information (Hogan 1998). This model suggests that the technology should compare favorably with excavation from a cost basis for larger sites

    Background Pilot studies can play an important role in qualitative studies. Methodological and practical issues can be shaped and refined by undertaking pilots. Personal development and researchers' competence are enhanced and lessons learned can inform the development and quality of the main study. However, pilot studies are rarely published, despite their potential to improve knowledge and understanding of the research. Aim To present the main lessons learned from undertaking a pilot in a qualitative PhD study. Discussion This paper draws together lessons learned when undertaking a pilot as part of a qualitative research project. Important methodological and practical issues identified during the pilot study are discussed including access, recruitment, data collection and the personal development of the researcher. The resulting changes to the final study are also highlighted. Conclusion Sharing experiences of and lessons learned in a pilot study enhances personal development, improves researchers' confidence and competence, and contributes to the understanding of research. Implications for practice Pilots can be used effectively in qualitative studies to refine the final design, and provide the researcher with practical experience to enhance confidence and competence.

    The dissolution of Idaho Nuclear Technology and Engineering Center (INTEC) pilot plant calcines was examined to determine solubility of calcine matrix components in acidic media. Two representatives pilot plant calcine types were studied: Zirconia calcine and Zirconia/Sodium calcine. Dissolution of these calcines was evaluated using lower initial concentrations of nitric acid than used in previous tests to decrease the [H+] concentration in the final solutions. Lower [H+] concentrations contribute to more favorable TRUEX/SREX solvent extraction flowsheet performance. Dissolution and analytical results were also obtained for radioactive calcines produced using high sodium feeds blended with non-radioactive Al(NO{sub 3}){sub 3} solutions to dilute the sodium concentration and prevent bed agglomeration during the calcination process. Dissolution tests indicated {gt}95 wt.% of the initial calcine mass can be dissolved using the baseline dissolution procedure, with the exception that higher initial nitric acid concentrations are required. The higher initial acid concentration is required for stoichiometric dissolution of the oxides, primarily aluminum oxide. Statistically designed experiments using pilot plant calcine were performed to determine the effect of mixing rate on dissolution efficiency. Mixing rate was determined to provide minimal effects on wt.% dissolution. The acid/calcine ratio and temperature were the predominate variables affecting the wt.% dissolution, a result consistent with previous studies using other similar types of pilot plant calcines.

    The technology transfer application this report describes is the result of a pilot study of image-processing methods applied to the image enhancement, coding, and analysis of arteriograms. Angiography is a subspecialty of radiology that employs the introduction of media with high X-ray absorption into arteries in order to study vessel pathology as well as to infer disease of the organs supplied by the vessel in question.

  17. PILOT STUDY: CCQM-P13 pilot study. Metals in artificial food digest

    2003-01-01

    The accuracy of elemental analyses in complex matrices is usually assessed by analysis of a suitable matrix reference material. The reference value is ascribed by consensus mean and by application of primary methods of analysis. However, the quality of this value will be affected by problems such as matrix-induced interferences, moisture corrections and heterogeneity. Pilot study CCQM-P13 was undertaken to assess the capabilities of National Metrology Institutes to analyse Ca, Cu and Cd in an acidic solution that simulates the digest of a food sample. This study filled the gap between the analysis of a gravimetrically prepared calibration solution and the analysis of an unknown in a complex matrix requiring extensive sample preparation. Having an independent reference value, with a small uncertainty, allowed a more rigorous estimation of the reliability of the institutes' analysis and uncertainty estimates, without including issues around sample digestion. The reference values were: 1.6617 +/- 0.0020 µmol/g for Ca, 7.037 +/- 0.012 nmol/g for Cu and 45.57 +/- 0.10 pmol/g for Cd (expanded uncertainties are quoted with coverage factor of 2). The other elements in the matrix were: Na (~25 µg/g), K (~90 µg/g), Cl (~120 µg/g), Fe (~100 ng/g), Mg (~5 µg/g), P (~5 µg/g), Sn (~80 ng/g) and Zn (~200 ng/g). Twelve international laboratories, representing eight countries, determined the amount content of the analytes. A range of techniques that include ID-ICP-MS (high resolution and collision cell), ICP-MS, ICP-OES, AAS, voltametry and potentiometry were used. The results for this pilot study averaged: 1.654 +/- 0.058 µmol/g for Ca (n = 10), 7.26 +/- 0.53 nmol/g for Cu (n = 12) and 45.2 +/- 5.1 pmol/g for Cd (n = 11) where the values associated with the averages are the standard deviations of n participants.

  18. Breakthrough Listen on MWA Pilot Study

    NASA Astrophysics Data System (ADS)

    Croft, S.; Siemion, A.; Kaplan, D. L.; Tremblay, S.

    2016-07-01

    We propose a pilot study, using the Voltage Capture System, for Breakthrough Listen on the MWA. Breakthrough Listen (BL) is a major new project that aims to dramatically improve the coverage of parameter space in the search for intelligent life beyond Earth. BL has already deployed hardware and software to the Green Bank Telescope, and will bring a similar program with the Parkes Telescope online in the second half of 2016. The low frequency sky is however currently very poorly explored. The superb capabilities of the MWA (large field of view, low frequency of operation, and location in a very radio quiet site) provide a unique opportunity for a pilot study to obtain voltage data for a SETI (Search For Extraterrestrial Intelligence) study of the Galactic Plane. We propose commensal observations, piggybacking on the proposed pulsar search of Tremblay et al. Using existing VCS software, combined with the pipeline developed for Breakthrough Listen at GBT and Parkes, we will perform a blind search for candidate signals from extraterrestrial intelligence. Although the chances of a detection are not large, particularly for a pilot study such as that proposed here, the Breakthrough Listen team plan to perform extensive testing and analysis on the data obtained which should be useful for other users of the MWA VCS. We will make the secondary SETI data products and associated documentation available as a resource to the community via the Breakthrough Listen online archive.

  19. The Role and Interpretation of Pilot Studies in Clinical Research

    PubMed Central

    Leon, Andrew C.; Davis, Lori L.; Kraemer, Helena C.

    2010-01-01

    Pilot studies represent a fundamental phase of the research process. The purpose of conducting a pilot study is to examine the feasibility of an approach that is intended to be used in a larger scale study. The roles and limitations of pilot studies are described here using a clinical trial as an example. A pilot study can be used to evaluate the feasibility of recruitment, randomization, retention, assessment procedures, new methods, and implementation of the novel intervention. A pilot study is not a hypothesis testing study. Safety, efficacy and effectiveness are not evaluated in a pilot. Contrary to tradition, a pilot study does not provide a meaningful effect size estimate for planning subsequent studies due to the imprecision inherent in data from small samples. Feasibility results do not necessarily generalize beyond the inclusion and exclusion criteria of the pilot design. A pilot study is a requisite initial step in exploring a novel intervention or an innovative application of an intervention. Pilot results can inform feasibility and identify modifications needed in the design of a larger, ensuing hypothesis testing study. Investigators should be forthright in stating these objectives of a pilot study. Grant reviewers and other stakeholders should expect no more. PMID:21035130

    1960-01-01

    A research program the general objective of which was to measure the effects of various sustained accelerations on the control performance of pilots, was carried out on the Aviation Medical Acceleration Laboratory centrifuge, U.S. Naval Air Development Center, Johnsville, PA. The experimental setup consisted of a flight simulator with the centrifuge in the control loop. The pilot performed his control tasks while being subjected to acceleration fields such as might be encountered by a forward-facing pilot flying an atmosphere entry vehicle. The study was divided into three phases. In one phase of the program, the pilots were subjected to a variety of sustained linear acceleration forces while controlling vehicles with several different sets of longitudinal dynamics. Here, a randomly moving target was displayed to the pilot on a cathode-ray tube. For each combination of acceleration field and vehicle dynamics, pilot tracking accuracy was measured and pilot opinion of the stability and control characteristics was recorded. Thus, information was obtained on the combined effects of complexity of control task and magnitude and direction of acceleration forces on pilot performance. These tests showed that the pilot's tracking performance deteriorated markedly at accelerations greater than about 4g when controlling a lightly damped vehicle. The tentative conclusion was also reached that regardless of the airframe dynamics involved, the pilot feels that in order to have the same level of control over the vehicle, an increase in the vehicle dynamic stability was required with increases in the magnitudes of the acceleration impressed upon the pilot. In another phase, boundaries of human tolerance of acceleration were established for acceleration fields such as might be encountered by a pilot flying an orbital vehicle. A special pilot restraint system was developed to increase human tolerance to longitudinal decelerations. The results of the tests showed that human tolerance

  4. The Influence of Loss of Visual Cues on Pilot Performance During the Final Approach and Landing Phase of a Remotely Piloted Vehicle Mission

    NASA Technical Reports Server (NTRS)

    Howard, James C.

    1976-01-01

    Remotely piloted research vehicles (RPRVS) are currently being flown from fixed-base control centers, and visual information is supplied to the remote pilot by a TV camera mounted in the vehicle. In these circumstances, the possibility of a TV failure or an interruption in the downlink to the pilot must be considered. To determine the influence of loss of TV information on pilot performance during the final approach and landing phase of a mission, an experiment was conducted in which pilots were asked to fly a fixed-base simulation of a Piper PA-30 aircraft with loss of TV information occurring at altitudes of 15.24, 30.48, and 45.72 m (50, 100, and 150 ft). For this experiment, a specially designed display configuration was presented to four pilots in accordance with a Latin square design. Initial results indicate that pilots could not ensure successful landings from altitudes exceeding 15.24 m (.50 ft) without the visual cues supplied by the TV picture.

    The number of crew members in commercial flights has decreased to two members, down from the five-member crew required 50 years ago. One question of interest is whether the crew should be reduced to one pilot. In order to determine the critical factors involved in safely transitioning to a single pilot, research must examine whether any performance deficits arise with the loss of a crew member. With a concrete understanding of the cognitive and behavioral role of a co-pilot, aeronautical technologies and procedures can be developed that make up for the removal of the second aircrew member. The current project describes a pre-study walkthrough process that can be used to help in the development of scenarios for testing future concepts and technologies for single pilot operations. Qualitative information regarding the tasks performed by the pilots can be extracted with this technique and adapted for future investigations of single pilot operations.

    Tinnitus is the perception of sound in the absence of an external stimulus. It is a frequent condition for which there is as yet no pharmacological treatment approved. Auditory and non-auditory pathways are involved in tinnitus' pathophysiology. Oxytocin is a neurohormone and eventual neurotransmitter that plays a complex role in social cognition and behavior. To evaluate the potential of oxytocin as a tinnitus treatment. Two studies were performed. Study 1 was a long-term open pilot study, while study 2 investigated short-term effects with a double-blinded placebo-controlled cross-over study. Ambulatory ENT care. In study 1, 15 patients were investigated over a 10-week period in an open pilot study. In study 2, 16 patients were included in a placebo-controlled crossover trial to investigate short-term effects following a single dose. For the long-term study (study 1), analysis of variance revealed a significant decrease in tinnitus sensation, both for the Tinnitus Handicap Inventory and Clinical Global Impression (CGI). Also, the short-term effects in study 2 revealed a significant reduction of tinnitus because of the oxytocin nasal spray as measured with the Visual Analog Scale and the CGI Scale. These preliminary studies demonstrated that oxytocin may represent a helpful tool for treating tinnitus and further larger controlled studies are warranted.

  7. Helicopter pilot back pain: a preliminary study.

    PubMed

    Shanahan, D F; Reading, T E

    1984-02-01

    Because of the high prevalence of back pain experienced by U.S. Army helicopter pilots, a study was conducted to ascertain the feasibility of reproducing these symptoms in the laboratory. A mock-up of a UH-1H seat and control configuration was mounted to a multi-axis vibration simulator (MAVS). Eleven subjects were tested on the apparatus for two 120-min periods. During one period, the MAVS was programmed to reproduce vibrations recorded from a UH-1H in cruise flight. The subjects received no vibration during the other test period. All subjects reported back pain which they described as identical to the pain they experience during flight, during one or more of their test periods. There was no statistical difference between the vibration and nonvibration test conditions (p greater than 0.05) in terms of time of onset of pain or intensity of pain as measured by a visual analog scale. It appears the vibration at the frequencies and amplitudes tested plays little or no role in the etiology of the back symptoms reported by these pilots. It is proposed that the primary etiological factor for these symptoms is the poor posture pilots are obliged to assume for extended periods while operating helicopters.

    2009-10-01

    Classical T Tauri stars (CTTS) are young, accreting systems. The accretion is thought to cause a soft X-ray excess and unusual line ratios in the He-like triplets. The accretion spots can also be seen with optical Doppler-imaging; however, the final test to correlate these signatures - simultaneous X-ray and ground-based observations - is still missing. We propose a 15 ks pilot study of MN Lup, the prime target for simultaneous observations from the optical point of view, to confirm its CTTS status and characterize its X-ray properties.

    From 1990 to 1992 the allergy profile of 1042 prospective hairdressers (personal and family history, atopic skin, serum IgE, patch and prick tests) was determined and their occupational suitability was evaluated. Up to 1997 a follow up of 375 hairdressers was obtained by way of questionnaires, re-examination, official reports and expert opinions of the social accident insurance. The frequency of initial eczema was 30%. A change of occupation on account of hairdresser eczema was documented in 11%. The prognostic evaluation of occupational suitability proved to be unsatisfactory. In this longitudinal study, the frequency of pre-occupational skin symptoms increased from 13 to 18%. The other atopic criteria indicated no uniform tendency. There was a significant increase in nickel allergy from 18.7 to 45.5% resulting partly from sensitization after entering the occupation and partly from an increase in nickel allergy at time of entry. Both atopic skin and pre-occupational nickel allergy increase the risk of hairdresser eczema, it is not so great as to justify dissuading such young people from entering the profession.

    1993-01-01

    A piloted simulation study was conducted to examine the requirements for using electromechanical flight instrumentation to provide situation information and flight guidance for manually controlled flight along curved precision approach paths to a landing. Six pilots were used as test subjects. The data from these tests indicated that flight director guidance is required for the manually controlled flight of a jet transport airplane on curved approach paths. Acceptable path tracking performance was attained with each of the three situation information algorithms tested. Approach paths with both multiple sequential turns and short final path segments were evaluated. Pilot comments indicated that all the approach paths tested could be used in normal airline operations.

    Work-related stress is a complex problem requiring a work environment-based assessment. Artists like dancers represent a category of atypical workers potentially at high risk for work-related stress. Aim of our pilot study is to evaluate organizational stress in a population of professional dancers, using the HSE Indicator Tool for Work Related Stress. We administered the Italian version of the HSE Indicator Tool to 38 ballet dancers, males and females. The questionnaire evaluates 7 key organizational dimensions: demand, control, managers' support, peer support, relationships, role and change. The standards required-ideal conditions are achieved in none of the above-mentioned dimensions. Change is the only dimension for which results fall between the 20th and the 50th percentile, while for other dimensions results fall below the 20th percentile suggesting the need for immediate corrective action. In male dancers an acceptable situation is highlighted for the dimension "change" compared to female dancers. In both sexes there is a high frequency of subjects complaining of verbal abuse, bullying and harassment. Despite the small sample size, our pilot study highlights the presence of heightened levels of organizational stress. Preventive measures targeted towards improving communication between managers and dancers and aimed at team building should be implemented.

    The pilot study reported in this paper was devised to develop and compare service delivery models that would achieve the provision of high quality parenteral therapy care to patients in the Gold Coast District Health Service community. All data were collected on 113 patients for a 12-month period, January to December 1996. The study compared the provision of outreach nursing services and contracted nursing services on measures of satisfaction and cost. The study showed that patient and carers indicated a preference for community care, medical officers advocated the benefits of administering parenteral therapies in the community, general practitioners were interested in managing future community parenteral therapies, and contracted (nurse) service providers endorsed the development of a parenteral therapy resource centre. The findings also revealed considerable potential cost savings in community-based care.

    The DOE's Big Sky Regional Carbon Sequestration Partnership has completed drilling the first continental flood basalt sequestration pilot borehole to a total depth (TD) of 4,110 feet on the Boise White Paper Mill property at Wallula, Washington. Site suitability was assessed prior to drilling by the 2007-2008 acquisition, processing and analysis of a four-mile, five-line three component seismic swath, which was processed as a single data-dense line. Analysis of the seismic survey data indicated a composite basalt formation thickness of {approx}8,000 feet and absence of major geologic structures (i.e., faults) along the line imaged by the seismic swath. Drilling of Wallula pilot borehole was initiated on January 13, 2009 and reached TD on April 6, 2009. Based on characterization results obtained during drilling, three basalt breccia zones were identified between the depth interval of 2,716 and 2,910 feet, as being suitable injection reservoir for a subsequent CO2 injection pilot study. The targeted injection reservoir lies stratigraphically below the massive Umtanum Member of the Grande Ronde Basalt, whose flow-interior section possesses regionally recognized low-permeability characteristics. The identified composite injection zone reservoir provides a unique and attractive opportunity to scientifically study the reservoir behavior of three inter-connected reservoir intervals below primary and secondary caprock confining zones. Drill cuttings, wireline geophysical logs, and 31one-inch diameter rotary sidewall cores provided geologic data for characterization of rock properties. XRF analyses of selected rock samples provided geochemical characterizations of the rocks and stratigraphic control for the basalt flows encountered by the Wallula pilot borehole. Based on the geochemical results, the pilot borehole was terminated in the Wapshilla Ridge 1 flow of the Grande Ronde Basalt Formation.

    The Idaho National Engineering Laboratory (INEL) is developing new methods to produce high-density aggregate (artificial rock) primarily consisting of depleted uranium oxide. The objective is to develop a low-cost method whereby uranium oxide powder (UO[sub 2], U[sub 3]O[sub ]8, or UO[sub 3]) can be processed to produce high-density aggregate pieces (DU-AGG) having physical properties suitable for disposal in low-level radioactive disposal facilities or for use as a component of high-density concrete used as shielding for radioactive materials. A commercial company, G-M Systems, conducted a design study for a manufacturing pilot plant to process DU-AGG. The results of that study are included and summarized in this report. Also explained are design considerations, equipment capacities, the equipment list, system operation, layout of equipment in the plant, cost estimates, and the proposed plan and schedule.

    This pilot study project explored the problem of providing access to the nomadic worker who desires to connect a computer through network access points at a number of different locations within the SNL/NM campus as well as outside the campus. The design and prototype development gathered knowledge that may allow a design to be developed that could be extended to a larger number of SNL/NM network drop boxes. The focus was to provide a capability for a worker to access the SNL IRN from a network drop box (e.g. in a conference room) as easily as when accessing the computer network from the office normally used by the worker. Additional study was done on new methods to authenticate the off campus worker, and protect and control access to data.

    Airline pilots may be at increased risk of venous thromboembolism (VTE) because air travel has recently been established as a risk factor for VTE. The aim of this study was to assess the risk of VTE in a cohort of Dutch airline pilots. Airline pilots who had been active members of the Dutch aviation society (VNV) were questioned for the occurrence of VTE, presence of risk factors for VTE and number of flight hours per year and rank. Incidence rates among pilots were compared with those of the general Dutch population and with a population of frequently flying employees of multinational organizations. A total of 2630 male pilots were followed-up for a total of 20420 person-years (py). Six venous thromboses were reported, yielding an incidence rate of 0.3 per 1000 py. The standardized morbidity ratio, comparing these pilots with the general Dutch population adjusted for age, was 0.8. Compared with the international employee cohort, the standardized morbidity ratio was 0.7 when all employees were included and 0.6 when only the frequently travelling employees were included. The incidence rate did not increase with number of flight hours per year and did not clearly vary by rank. We conclude that the risk of VTE is not increased amongst airline pilots. © 2014 International Society on Thrombosis and Haemostasis.

    This pilot study was conducted to determine areas in which additional education regarding the human immunodeficiency virus (HIV) is needed by the undocumented and recently immigrated HIV-infected population, and to obtain preliminary information on the ability of this community to access medical treatment for HIV. Information regarding health status, immigration status, and the use of medical services was obtained from all HIV-infected undocumented and recently immigrated individuals who sought services from a Southern California nonprofit agency between July 1, 1990 and December 31, 1990. A total of 54 such individuals presented for services. Thirteen individuals reported participating in shared needle usage for the administration of medication or vitamins, in addition to other known risk factors for HIV. Only one of these 13 individuals had access to nonemergency medical care. Additional research is necessary to determine the reasons for these needle sharing behaviors. Educational outreach is needed to address these behaviors as a possible risk factor for HIV transmission.

  12. Pilot-scale production of grout with simulated double-shell slurry feed. Final report

    SciTech Connect

    Whyatt, G.A.

    1994-08-01

    This report describes the pilot-scale production of grout with simulated double-shell slurry feed (DSSF) waste performed in November 1988, and the subsequent thermal behavior of the grout as it cured in a large, insulated vessel. The report was issued in draft form in April 1989 and comments were subsequently received; however, the report was not finalized until 1994. In finalizing this report, references or information gained after the report was drafted in April 1989 have not been incorporated to preserve the report`s historical perspective. This report makes use of criteria from Ridelle (1987) to establish formulation criteria. This document has since been superseded by a document prepared by Reibling and Fadeef (1991). However, the reference to Riddelle (1987) and any analysis based on its content have been maintained within this report. In addition, grout is no longer being considered as the waste form for disposal of Hanford`s low-level waste. However, grout disposal is being maintained as an option in case there is an emergency need to provide additional tank space. Current plans are to vitrify low-level wastes into a glass matrix.

  13. The influence of radio altimeter errors on pilot performance during the final approach and landing phase of an RPV mission

    Howard, J. C.

    1975-01-01

    Due to the fact that remotely piloted vehicles (RPV's) are currently being flown from fixed base control centers, kinesthetic and real world peripheral vision cues are absent. The absence of these cues complicates the piloting task, particularly during the final approach and landing phase of a mission. The pilot's task is futher complicated by errors in the displayed altitude information. To determine the influence of these errors on pilot performance during the final approach and landing phase of a mission, an experiment was conducted in which pilot subjects were asked to fly a fixed base simulation of a Piper PA-30 aircraft, using degraded altitude information. For this experiment, the chevron component of the display configuration was driven by a radio altimeter. Four altimeters were used, each with a different error characteristic, but within the range specified for the Sperry series of radio altimeters. Results indicate that for range of errors considered, there is no significant difference in landing performance that can be attributed to errors in altitude information.

    This bench-unit program simulated the Catlettsburg H-Coal Pilot Plant start-up procedure in Run 6, which used catalytic cracker slurry oil, an aromatic petroleum oil. The program was designed to explore the reasons for Pilot Plant operational difficulties which included reactor product instability, vacuum pumping difficulties and unexpected product yields. Startup oil, hydroclone overflow and withdrawn catalyst were obtained from the Pilot Plant for use in this run with Illinois No. 6 coal. In this run the ratio of startup oil/coal was varied in Periods 1-10, from 2 to 0.2, while the ratio of recycle oil to coal was increased from 0 to 1.8. Recycle oils generated during this run were used as slurry oils in Periods 11 and 12. Initially, the C/sub 4/-975/sup 0/F total distillate yield was 57.4 W %. As the startup oil feed was eliminated later in the run, the C/sub 4/-974/sup 0/F yield fell to 45.4 W %. Ancillary studies were performed on separator bottoms in order to establish their viscosity and settling characteristics as a function of time. Viscosity measurements were also made on bottoms containing 1 to 30 W % 975/sup 0/F/sup -/ distillate. For comparison, viscosities were measured as a function of temperature using PDU Run 5 hydroclone overflow samples which were vacuum distilled to contain < 33 W % 975/sup 0/F distillate. The propensity toward carbon formation was investigated by a series of Ramsbottom carbon residue (RCR) measurements on separator bottoms which covered the range of startup oil/coal ratios from 2 to 0. Finally, microautoclave tests were performed on startup oil and hydroclone overflow oils in order to assess their ability to dissolve coal.

  15. Advanced Design Studies. Final report

    Steiner, Don

    2012-12-01

    The ARIES-CS project was a multi-year multi-institutional project to assess the feasibility of a compact stellarator as a fusion power plant. The work herein describes efforts to help design one aspect of the device, the divertor, which is responsible for the removal of particle and heat flux from the system, acting as the first point of contact between the magnetically confined hot plasma and the outside world. Specifically, its location and topology are explored, extending previous work on the sub ject. An optimized design is determined for the thermal particle flux using a suite of 3D stellarator design codes which trace magnetic field lines from just inside the confined plasma edge to their strike points on divertor plates. These divertor plates are specified with a newly developed plate design code. It is found that a satisfactory thermal design exists which maintains the plate temperature and heat load distribution below tolerable engineering limits. The design is unique, including a toroidal taper on the outboard plates which was found to be important to our results. The maximum thermal heat flux for the final design was 3.61 M W/m2 and the maximum peaking factor was 10.3, below prescribed limits of 10 M W/m2 and 15.6, respectively. The median length of field lines reaching the plates is about 250 m and their average angle of inclination to the surface is 2 deg. Finally, an analysis of the fast alphas, resulting from fusion in the core, which escape the plasma was performed. A method is developed for obtaining the mapping from magnetic coordinates to real-space coordinates for the ARIES-CS. This allows the alpha exit locations to be identified in real space for the first time. These were then traced using the field line algorithm as well as a guiding center routine accounting for their mass, charge, and specific direction and energy. Results show that the current design is inadequate for accommodating the alpha heat flux, capturing at most 1/3 of lost alphas

    Traffic volume and speed is going to be increased in Indian Railways successively, leading to higher stress in staff connected with train operations. The jobs of railway engine pilots come under the category of high-strain jobs, necessitating a need to conduct multicentric study to unfold the factors associated with occupational stress and organizational strategies. Present study covered 185 railway engine pilots and office clerks working in various railway zones by incidental method. Occupational Stress Index (OSI) test developed by Srivastva and Singh, questionnaire of specific stressors constructed by authors and laboratory test battery for psychological screening of high-speed train pilots were used as tools. Means of OSI and all the 12 occupational stressors of railway engine pilots were found significantly higher to that of office clerks. Means of OSI and occupational stressors of goods train pilots were significantly higher in comparison to high-speed train pilots and passenger train pilots. Study revealed positive correlation of speed perception and complex reaction time tests and negative correlation of other constituent tests of laboratory test battery to OSI test. Highest subgroup of stressor observedwas role overload followed by role conflict. These findings provide a prima facie evidence of higher occupational stress among railway engine pilots because of identified specific stressors prevalent in their job and explore the possible intervention strategies for its reduction. Significant correlation is noticed between OSI and laboratory test results, indicating its relevant utility in preliminary psychological screening.

    Twenty-nine urban inhabitants participated in a half-day climatotherapy programme at the moderate mountain area and lowland area in the northwest part of the main island of Japan. The current study was aimed to investigate physically and mentally the objective and subjective influence of our short programme, which was a prospective pilot study of single intervention. Blood pressure was significantly descended during terrain cure at the uphill mountain path and returned after fresh-air rest cure, while there was no significant change throughout the programme at lowland flat path. Heart rate was significantly ascended and descended at both area, and more clearly changed at the mountain path. Profile of Mood Status brief form Japanese version administered before and after our half-day programme. Age adjusted T score of negative subscales, `tension-anxiety', `depression', `anger-hostility', `fatigue' and `confusion' were significantly lower after climatotherapy at both sites. Whereas, there was no significant change concerning `vigour' score. This short-version climatotherapy programme has been designed for people without enough time for long stay at health resort. It turned out our half-day climatotherapy programme contribute to mood status improvement. In addition, repeated practice of our short-version programme including endurance exercise with cool body shell using uphill path can be expected that blood pressure will go toward the normal range and heart rate will decrease both in usual time and during exercise. Therefore, health benefits can be expected of this climatotherapy programme.

    The aim of this in vivo pilot study was to record variations in temperature at various sites in a subject's mouth in response to a standardised thermal challenge and to determine a more realistic thermocycling regimen for future use. A volunteer who suffered from no dentinal hypersensitivity had modified study models prepared for constructing vacuum-formed PVC splints. Perforations 2 mm in diameter were placed for thermocouples facially and lingually in the midcoronal sites of the upper and lower central incisors, canines, second premolars, and second molars to measure temperatures at these sites. A standardised drinking regimen was followed of hot black coffee (72.5 degrees C) followed by cold orange juice (6.0 degrees C). Contralateral sites experienced similar temperature changes of short duration. A maximum of 68.0 degrees C and a minimum of 15.4 degrees C were recorded. Less extreme temperatures were experienced posteriorly, and little or no discernible changes were noted at the facial aspects of the upper second molars or lingually on the lower second molars. Most commonly used thermocycling regimens are clinically unrealistic, and temperatures vary widely throughout the mouth when hot or cold drinks are taken.

    A Department of Energy (DOE) multi-laboratory Water Cycle Pilot Study (WCPS) investigated components of the local water budget at the Walnut River Watershed in Kansas to study the relative importance of various processes and to determine the feasibility of observational water budget closure. An extensive database of local meteorological time series and land surface characteristics was compiled. Numerical simulations of water budget components were generated and, to the extent possible, validated for three nested domains within the Southern Great Plains; the DOE Atmospheric Radiation Measurement/Cloud Atmospheric Radiation Testbed (ARM/CART), the Walnut River Watershed (WRW), and the Whitewater Watershed (WW), Kansas A 2-month Intensive Observation Period (IOP) was conducted to gather detailed observations relevant to specific details of the water budget, including fine-scale precipitation, streamflow, and soil moisture measurements not made routinely by other programs. Event and season al water isotope (delta 18O, delta D) sampling in rainwater, streams, soils, lakes, and wells provided a means of tracing sources and sinks within and external to the WW, WRW, and the ARM/CART domains. The WCPS measured changes in leaf area index for several vegetation types, deep groundwater variations at two wells, and meteorological variables at a number of sites in the WRW. Additional activities of the WCPS include code development toward a regional climate model with water isotope processes, soil moisture transect measurements, and water level measurements in ground water wells.

    Entombed waste in current sanitary landfills will generate biogas and leachate when physical barriers fail in the future, allowing the intrusion of moisture into the waste mass contradicting the precepts of the sustainability concept. Bioreactor landfills are suggested as a sustainable option to achieve Final Storage Quality (FSQ) status of waste residues; however, it is not clear what characteristics the residues should have in order to stop operation and after-care monitoring schemes. An experiment was conducted to determine the feasibility to achieve FSQ status (Waste Acceptance Criteria of the European Landfill Directive) of residues in a pilot scale bioreactor landfill. The results of the leaching test were very encouraging due to their proximity to achieve the proposed stringent FSQ criterion after 2 years of operation. Furthermore, residues have the same characteristics of alternative waste stabilisation parameters (low BMP, BOD/COD ratio, VS content, SO4(2-)/Cl- ratio) established by other researchers. Mass balances showed that the bioreactor landfill simulator was capable of practically achieving biological stabilisation after 2 years of operation, while releasing approximately 45% of the total available (organic and inorganic) carbon and nitrogen into the liquid and gas phases.

    The Inyan Kara Formation provides an abundant source of warm (54 to 71/sup 0/C) but salty (7400 mg/l combined Na and Cl ions) water for much of southwestern North Dakota. The city of Dickinson, ND, overlies this aquifer at 1676 to 1768 meters. This study investigates the potential of usng this hydrothermal resource as an energy source for a district heating system in a new undeveloped addition to Dickinson. In addition, the use of a reverse osmosis system to desalinate the water is considered along with other water treatment processes necessary to allow use of this water in the existing city water supply. The results of the study indicate the economic requirements to make this concept feasible and outline the consideration to carry the project into the design phase.

    1992-01-01

    A two phase piloted simulation study was conducted to investigate alternative wing and flap controls for tilt-wing aircraft. The initial phase of the study compared the flying qualities of both a conventional (programmed) flap and an innovative geared flap. The second phase of the study introduced an alternate method of pilot control for the geared flap and further studied the flying qualities of the programmed flap, and two geared flap configurations. In general, the pilot ratings showed little difference between the programmed flap and the geared flap control concepts, although differences between the two control concepts were noticed and are discussed in this paper. The addition of pitch attitude stabilization in the second phase of the study greatly enhanced the aircraft flying qualities. This paper describes the simulated tilt-wing aircraft and the flap control concepts, and presents the results of both the first and second phases of the piloted simulation study.

    Many simple (without thermal effects) ground-water flow models have been used for analysis of water resource problems since the 1960`s. The emphasis on more complicated ground-water flow models began to shift with the focus on waste management problems during the 1970`s. The ground-water flow model development has shifted to unsaturated flow models because the unsaturated zone at Yucca Mountain was selected as a potential high-level radioactive waste disposal site. Many unsaturated flow models have been developed and used since the mid-1980`s. A few unsaturated flow models have also been developed in the 1990`s. Under the U.S. Department of Energy (DOE), the Civilian Radioactive Waste Management System Management and Operating Contractor (CRWMS M&O) has the responsibility to review, evaluate, and document the existing computer models; to conduct performance assessments; and to develop performance assessment models, where necessary. Two major regulatory requirements are the main criteria for selection of ground-water flow models in the unsaturated zone. One is of calculating the pre-emplacement ground-water travel time. Our work has focused on visualization techniques, and experiments that could have more application quantitatively. Many studies are summarized in this report.

    The radiation exposure dose was estimated for the Waste Isolation Pilot Plant (WIPP) operating personnel who do the unloading and transporting of the transuranic contact-handled waste. Estimates of the radiation source terms for typical TRU contact-handled waste were based on known composition and properties of the waste. The operations sequence for waste movement and storage in the repository was based upon the WIPP Title I data package. Previous calculations had been based on Conceptual Design Report data. A time and motion sequence was developed for personnel performing the waste handling operations both above and below ground. Radiation exposure calculations were then performed in several fixed geometries and folded with the time and motion studies for individual workers in order to determine worker exposure on an annual basis.

    Background Tobacco smoking is a serious risk to health: several therapies are available to assist those who wish to stop. Smokers who approach publicly funded stop-smoking clinics in the UK are currently offered nicotine replacement therapy (NRT) or bupropion, and group behaviour therapy, for which there is evidence of effectiveness. Acupuncture and acupressure are also used to help smokers, though a systematic review of the evidence of their effectiveness was inconclusive. The aim of this pilot project was to determine the feasibility of a study to test acupressure as an adjunct to one anti-smoking treatment currently offered, and to inform the design of the study. Methods An open randomised controlled pilot study was conducted within the six week group programme offered by the Smoking Advice Service in Plymouth, UK. All participants received the usual treatment with NRT and group behavioural therapy, and were randomised into three groups: group A with two auricular acupressure beads, group B with one bead, and group C with no additional therapy. Participants were taught to press the beads when they experienced cravings. Beads were worn in one ear for four weeks, being replaced as necessary. The main outcome measures assessed in the pilot were success at quitting (expired CO ≤ 9 ppm), the dose of NRT used, and the rating of withdrawal symptoms using the Mood and Symptoms Scale. Results From 49 smokers attending four clinics, 24 volunteered to participate, 19 attended at least once after quitting, and seven remained to the final week. Participants who dropped out reported significantly fewer previous quit attempts, but no other significant differences. Participants reported stimulating the beads as expected during the initial days after quitting, but most soon reduced the frequency of stimulation. The discomfort caused by the beads was minor, and there were no significant side effects. There were technical problems with adhesiveness of the dressing. Reporting of

    Pilot studies are meritorious for determining the feasibility of a definitive clinical trial in terms of conduct and potential for efficacy, but their possible applications for planning a future trial are not always fully realized. The purpose of this review was to estimate the extent to which pilot/feasibility studies: (i) addressed needed objectives; (ii) led to definitive trials; and (iii) whether the subsequent undertaking of a definitive trial was influenced by the strength of the evidence of outcome improvement. Trials published in the journal Clinical Rehabilitation, since its inception, were eligible if the word 'pilot' or 'feasibility' was specified somewhere in the article. A total of 191 studies were reviewed, results were summarized descriptively, and between-group effect sizes were computed. The specific purposes of piloting were stated in only 58% ( n = 110) of the studies. The most frequent purpose was to estimate the potential for efficacy (85%), followed by testing the feasibility of the intervention (60%). Only 12% of the studies were followed by a definitive trial; <4% of studies had a main study underway or a published study protocol. There was no relationship between observed effect size and follow-up of pilot studies, although the confidence intervals were very wide owing to small number of trials that followed on. Labelling and reporting of pilot studies needs to be improved to be concordant with the recently issued CONSORT guidelines. Feasibility needs to be fully tested and demonstrated prior to committing considerable human and monetary resources.

    Comparative metabolomics was carried out to investigate the metabolic differences of Penicillium chrysogenum in the pilot and industrial fermentations that resulted from the scale-up. By principal component analysis, the early stages of two fermentation processes were clearly distinguished, whereas the middle and final stages were clustered together. It indicated that the different metabolisms of cells in the pilot and industrial fermentations mainly existed during the early stage. Furthermore, the levels of polyamines, polyols, glycolysis, and tricarboxylic acid cycle intermediates, which changed more dramatically during the pilot process, were all higher in the pilot than in the industrial fermentation during the early stage. This indicated that the fermentation conditions of the early stage should be the focus of process management which is aimed at increasing penicillin production. Additionally, the comparative accumulations of the precursors of penicillin (valine, cysteine, and lysine) revealed that penicillin biosynthesis in the industrial process was more affected during the middle stage of fermentation. These findings provide new insights to further regulate the industrial process and improve the production of penicillin. More generally, this study attempts to address the scarcity of studies that contrast the metabolic outcomes between commercial- and pilot-scale conditions.

    This report describes the evaluations of the power production testing of Solar One, the 10 MW/sub e/ Solar Thermal Central Receiver Pilot Plant near Barstow, California. The Pilot Plant, a cooperative project of the US Department of Energy and utility firms led by the Southern California Edison Company, began a three year period of power production operation in August 1984. During this period, plant performance indicators, such as capacity factor, system efficiency, and availability, were studied to assess the operational capability of the Pilot Plant to reliably supply electrical power. Also studied was the long-term performance of such key plant components as the heliostats and the receiver. During the three years of power production, the Pilot Plant showed an improvement in performance. Considerable increases in capacity factor, system efficiency, and availability were achieved. Heliostat operation was reliable, and only small amounts of mirror corrosion were observed. Receiver tube leaks did occur, however, and were the main cause of the plant's unscheduled outages. The Pilot Plant provided valuable lessons which will aid in the design of future solar central receiver plants. 53 refs., 46 figs., 4 tabs.

    Birckelbaw, Lourdes G.; Corliss, Lloyd D.

    1994-01-01

    A two-phase piloted simulation study was conducted to investigate alternative wing and flap controls for tilt-wing aircraft. The initial phase of the study compared the flying qualities of both a conventional (programmed) flap and an innovative geared flap. The second phase of the study introduced an alternate method of pilot control for the geared flap and further studied the flying qualities of the programmed flap, and two geared flap configurations. In general, the pilot rating showed little variation between the programmed flap and the geared flap control concepts. Some differences between the two concepts were noticed and are discussed in this paper. The addition of pitch attitude stabilization in the second phase of the study greatly enhanced the aircraft flying qualities. This paper describes the simulated tilt-wing aircraft and the flap control concepts and presents the results of both phases of the simulation study.

    Establish whether the Sbisa bar, Bagolini filter (BF) bar, and neutral density filter (NDF) bar, used to measure density of suppression, are equivalent and possess test-retest reliability. Determine whether density of suppression is altered when measurement equipment/testing conditions are changed. Our pilot study had 10 subjects aged ≥18 years with childhood-onset strabismus, no ocular pathologies, and no binocular vision when manifest. Density of suppression upon repeated testing, with clinic lights on/off, and using a full/reduced intensity light source, was investigated. Results were analysed for test-retest reliability, equivalence, and changes with alteration of testing conditions. Test-retest reliability issues were present for the BF bar (median 6 filter change from first to final test, p = 0.021) and NDF bar (median 5 filter change from first to final test, p = 0.002). Density of suppression was unaffected by environmental illumination or fixation light intensity variations. Density of suppression measurements were higher when measured with the NDF bar (e.g. NDF bar = 1.5, medium suppression, vs BF bar = 6.5, light suppression). Test-retest reliability issues may be present for the two filter bars currently still under manufacture. Changes in testing conditions do not significantly affect test results, provided the same filter bar is used consistently for testing. Further studies in children with strabismus having active amblyopia treatment would be of benefit. Despite extensive use of these tests in the UK, this is to our knowledge the first study evaluating filter bar equivalence/reliability.

    2000-01-01

    One of the ongoing problems that pilots face today is a diminished state of awareness such as boredom, sleepiness, or fatigue during cruise conditions that could result in various pilot errors. This study utilized a cognitive training exercise to sharpen the pilot's awareness during simulated flight thereby providing them with a means to overcome these diminished states of awareness. This study utilizes psychophysiological methods in an attempt to assess a pilot's state of awareness more directly. In turn, the pilots will be able to train themselves to recognize these states of awareness and be more mentally sharp during mundane tasks such as those experienced in cruise conditions. The use of these measurement tools may be beneficial for researchers working within the NASA Aviation Safety Program. This paper will provide the reader with some background information concerning the motivation for the study, a brief description of the experimental setup and design matrix, the dependent and independent variables that were employed, and some preliminary findings based on some of the subjective and objective data that was collected. These preliminary findings are of part of an ongoing study being conducted at the NASA Langley Research Center in Hampton, Virginia.

    The Federal Motor Carrier Safety Administration (FMCSA) Wireless Roadside Inspection (WRI) Program is researching the feasibility and value of electronically assessing truck and bus driver and vehicle safety at least 25 times more often than is possible using only roadside physical inspections. The WRI program is evaluating the potential benefits to both the motor carrier industry and to government. These potential benefits include reduction in accidents, fatalities and injuries on our highways and keeping safe and legal drivers and vehicles moving on the highways. WRI Pilot tests were conducted to prototype, test and demonstrate the feasibility and benefits of electronically collecting safety data message sets from in-service commercial vehicles and performing wireless roadside inspections using three different communication methods. This report summarizes the design, conduct and results of the Tennessee CMRS WRI Pilot Test. The purpose of this Pilot test was to demonstrate the implementation of commercial mobile radio services to electronically request and collect safety data message sets from a limited number of commercial vehicles operating in Tennessee. The results of this test have been used in conjunction with the results of the complimentary pilot tests to support an overall assessment of the feasibility and benefits of WRI in enhancing motor carrier safety (reduction in accidents) due to increased compliance (change in motor carrier and driver behavior) caused by conducting frequent safety inspections electronically, at highway speeds, without delay or need to divert into a weigh station

  5. Prioritization strategies in clinical practice guidelines development: a pilot study

    PubMed Central

    2010-01-01

    Objective Few methodological studies address the prioritization of clinical topics for the development of Clinical Practice Guidelines (CPGs). The aim of this study was to validate a methodology for Priority Determination of Topics (PDT) of CPGs. Methods and results Firstly, we developed an instrument for PDT with 41 criteria that were grouped under 10 domains, based on a comprehensive systematic search. Secondly, we performed a survey of stakeholders involved in CPGs development, and end users of guidelines, using the instrument. Thirdly, a pilot testing of the PDT procedure was performed in order to choose 10 guideline topics among 34 proposed projects; using a multi-criteria analysis approach, we validated a mechanism that followed five stages: determination of the composition of groups, item/domain scoring, weights determination, quality of the information used to support judgments, and finally, topic selection. Participants first scored the importance of each domain, after which four different weighting procedures were calculated (including the survey results). The process of weighting was determined by correlating the data between them. We also reported the quality of evidence used for PDT. Finally, we provided a qualitative analysis of the process. The main domains used to support judgement, having higher quality scores and weightings, were feasibility, disease burden, implementation and information needs. Other important domains such as user preferences, adverse events, potential for health promotion, social effects, and economic impact had lower relevance for clinicians. Criteria for prioritization were mainly judged through professional experience, while good quality information was only used in 15% of cases. Conclusion The main advantages of the proposed methodology are supported by the use of a systematic approach to identify, score and weight guideline topics selection, limiting or exposing the influence of personal biases. However, the methodology was

    No longitudinal study should go into the field prior to detailed piloting and validation studies of the measures and techniques to be used. Preparation should also involve the training of staff, the acquisition of space and appropriate equipment, and liaison with the community and ethical committees as well as with scientific collaborators. Because different measures will continually be introduced as the participants age, the preparation, piloting and validation studies have to be ongoing. Here we describe some of the different strategies that should be used.

    There is a trend towards the increased use of automation in V&V. Automation can yield savings in time and effort. For critical systems, where thorough V&V is required, these savings can be substantial. We describe a progression from pilot studies to development and use of V&V automation. We used pilot studies to ascertain opportunities for, and suitability of, automating various analyses whose results would contribute to V&V. These studies culminated in the development of an automatic generator of automated test oracles. This was then applied and extended in the course of testing an Al planning system that is a key component of an autonomous spacecraft.

    1980-08-01

    Advanced Energy Dynamics, Inc. (AED), has developed a proprietary coal cleaning process which employs a combination of ionization and electrostatic separation to remove both sulfur and ash from dry pulverized coal. The Ohio Department of Energy sponsored the first part of a program to evaluate, develop, and demonstrate the process in a continuous-flow pilot plant. Various coals used by Ohio electric utilities were characterized and classified, and sulfur reduction, ash reduction and Btu recovery were measured. Sulfur removal in various coals ranged from 33 to 68% (on a Btu basis). Ash removal ranged from 17 to 59% (on a Btu basis). Ash removal of particles greater than 53 microns ranged from 46 to 88%. Btu recovery ranged from 90 to 97%. These results, especially the large percentage removal of ash particles greater than 53 microns, suggest that the AED system can contribute materially to improved boiler performance and availability. The study indicated the following potential areas for commercial utilization of the AED process: installation between the pulverizer and boiler of conventional coal-fired power utilities; reclamation of fine coal refuse; dry coal cleaning to supplement, and, if necessary, to take the place of conventional coal cleaning; upgrading coal used in: (1) coal-oil mixtures, (2) gasification and liquefaction processes designed to handle pulverized coal; and (3) blast furnaces for making steel, as a fuel supplement to the coke. Partial cleaning of coking coal blends during preheating may also prove economically attractive. Numerous other industrial processes which use pulverized coal such as the production of activated carbon and direct reduction of iron ore may also benefit from the use of AED coal cleaning.

  11. SUPERCRITICAL WATER PARTIAL OXIDATION PHASE I - PILOT-SCALE TESTING/FEASIBILTY SUDIES FINAL REPORT

    SciTech Connect

    SPRITZER.M; HONG,G

    2005-01-01

    General Atomics (GA) is developing Supercritical Water Partial Oxidation (SWPO) as a means of producing hydrogen from low-grade biomass and other waste feeds. The Phase I Pilot-scale Testing/Feasibility Studies have been successfully completed and the results of that effort are described in this report. The key potential advantage of the SWPO process is the use of partial oxidation in-situ to rapidly heat the gasification medium, resulting in less char formation and improved hydrogen yield. Another major advantage is that the high-pressure, high-density aqueous environment is ideal for reacting and gasifying organics of all types. The high water content of the medium encourages formation of hydrogen and hydrogen-rich products and is especially compatible with high water content feeds such as biomass materials. The high water content of the medium is also effective for gasification of hydrogen-poor materials such as coal. A versatile pilot plant for exploring gasification in supercritical water has been established at GA's facilities in San Diego. The Phase I testing of the SWPO process with wood and ethanol mixtures demonstrated gasification efficiencies of about 90%, comparable to those found in prior laboratory-scale SCW gasification work carried out at the University of Hawaii at Manoa (UHM), as well as other biomass gasification experience with conventional gasifiers. As in the prior work at UHM, a significant amount of the hydrogen found in the gas phase products is derived from the water/steam matrix. The studies at UHM utilized an indirectly heated gasifier with an activated carbon catalyst. In contrast, the GA studies utilized a directly heated gasifier without catalyst, plus a surrogate waste fuel. Attainment of comparable gasification efficiencies without catalysis is an important advancement for the GA process, and opens the way for efficient hydrogen production from low-value, dirty feed materials. The Phase I results indicate that a practical means to

    A pilot study of soil vapor extraction (SVE) at a gasoline-contaminated site in the Piedmont physiographic region of South Carolina is presented. The objective of the pilot study is to determine the efficacy of SVE in remediating petroleum-contaminated Piedmont sites. Soil of the Piedmont region is characterized by fine-grained materials that exhibit a stratified, anisotropic structure, often dominated by zones of low permeability. The pilot remediation project consists of a multiple-well SVE and air sparging system located in the contaminant source area. Hourly measurement of mass extraction rates show elevated hydrocarbon (HC) concentrations during the first hour of operation and a rapid decline to asymptotic values. Time-averaged hydrocarbon mass extraction rates range from 22 to 68 kg HC per day for eight SVE wells operating 6 to 8 h per day. Elevated levels of CO{sub 2} in extracted soil vapors indicate microbial activity contributing to bioremediation at the site.

    Despite the many dangers associated with smoking during pregnancy, it remains a salient public health problem for Wisconsin women. The First Breath pilot program was developed in an attempt to reduce rates of smoking during pregnancy among low-income women. Preliminary results suggest that the First Breath counseling-based approach is effective, with a quit rate of 43.8% among First Breath enrollees at 1 month postpartum. Women receiving First Breath cessation counseling also had higher quit rates at every measurement period versus women in a comparison group who were receiving whatever cessation care was available in their county in the absence of First Breath. The First Breath pilot study has demonstrated success in helping pregnant women quit smoking and in creating a model for integration of cessation services into prenatal health care service provision. It is through this success that First Breath is expanding beyond the pilot study stage to a statewide program in 2003.

    Breast neoplasms include different histopathological entities, varying from benign tumors to highly aggressive cancers. Despite the key role of imaging, traditional histology is still required for a definitive diagnosis. Confocal Laser Endomicroscopy (CLE) is a new technique, which enables to obtain histopathological images in vivo, currently used in the diagnosis of gastrointestinal diseases. This is a single-center pilot feasibility study; the main aim is to describe the basic morphological patterns of Confocal Laser Endomicroscopy in normal breast tissue besides benign and malignant lesions. Thirteen female patients (mean age 52.7, range from 22 to 86) who underwent surgical resection for a palpable breast nodule were enrolled. CLE was performed soon after resection with the Cellvizio® Endomicroscopy System (Mauna Kea Technologies, Paris, France), by using a Coloflex UHD-type probe; intravenous fluorescein was used as contrast-enhancing agent. The surgical specimen was cut along the main axis; dynamic images were obtained and recorded using a hand-held probe directly applied both to the internal part of the lesion and to several areas of surrounding normal tissue. Each specimen was then sent for definitive histologic examination. Histopathology revealed a benign lesion in six patients (46%), while a breast cancer was diagnosed in seven women (54%). Confocal laser endomicroscopy showed some peculiar morphological patterns. Normal breast tissue was characterized by a honeycomb appearance with regular, dark, round or hexagonal glandular lobules on a bright stroma background; tubular structures, representing ducts or blood vessels, were also visible in some frames. Benign lesions were characterized by a well-demarcated "slit-like" structure or by lobular structures in abundant bright stroma. Finally, breast cancer was characterized by a complete architectural subversion: ductal carcinoma was characterized by ill-defined structures, with dark borders and irregular

    this paper describes the pilot study that was undertaken to test the feasibility of the recruitment plan designed to recruit women who booked to give birth in two freestanding midwifery units in NSW, Australia. The pilot preceded the full prospective cohort study, Evaluating Midwifery Units (EMU), which aimed to examine the antenatal, birth and postnatal outcomes of women planning to give birth in freestanding midwifery units compared to those booked to give birth in tertiary level maternity units in Australia and New Zealand. a prospective cohort study with two mutually-exclusive cohorts. two freestanding midwifery units in NSW and their corresponding tertiary referral hospitals. a total of 146 women with few identified risk factors recruited between 13 September 2009 and 31 March 2010 whose planned place of birth was either a freestanding midwifery unit or tertiary maternity unit. the pilot study identified the feasibility of relying on the booking midwife to recruit eligible women from several antenatal booking clinics to the study. Low rates of eligible women were invited resulting in a lower than expected consent rate. In addition, although mostly only low-risk women were invited to participate, some women requiring medical consultation at the time of booking were inadvertently recruited into the study. The results of this pilot study led us to revise the study protocol to find ways of including the outcomes of all women without identified risk factors who booked at either the freestanding midwifery units or the tertiary referral hospital in that area. This paper describes the revisions that were made to the study plan. five lessons were learned from the pilot study. We found that recruitment protocols employed for the cohort study were too complicated and required simplification to maximise the potential of the study. The study protocol needed to be changed for the main study to ensure a larger sample size and to ensure the risk profile of each cohort was as

    Cu cermet anodes were tested for 213 to 614 hours with an in-situ deposited CEROX coating in a pilot cell operated by Reynolds Manufacturing Technology Laboratory. At high bath ratio ({approximately}1.5) and low current density (0.5 A/cm{sup 2}), a {ge}1 mm thick dense CEROX coating was deposited on the anodes. At lower bath ratios and higher current density, the CEROX coating was thinner and less dense, but no change in corrosion rate was noted. Regions of low current density on the anodes and sides adjacent to the carbon anode sometimes had thin or absent CEROX coatings. Problems with cracking and oxidation of the cermet substrates led to higher corrosion rates in a pilot cell than would be anticipated from lab scale results.

    1993-07-01

    To determine the feasibility of improving oil recovery and the economics of microbial enhanced waterflooding in mature oil wells in the United States, two field pilots have been conducted. Candidate fields were screened to determine whether they have any potential for a microbial system developed at the National Institute for Petroleum and Energy Research (NIPER), and microbial compatibility tests were conducted in the laboratory to select the target field. A specific microbial formulation was selected that was compatible with the chosen reservoir environment and had been shown to recover oil after waterflooding in Berea sandstone and field core. The microbial formulation was designed to improve microscopic oil displacement efficiency by surfactant, gas and acid production from fermentation of molasses. A 20-acre pilot test was initiated in October 1986, and completed in December 1989. Results from this pilot demonstrated that microorganisms could be injected into an ongoing waterflood and that such injection could increase oil production by at least 13%. A larger test (520 acres) was completed in the same formation to evaluate the feasibility of commercial application of the technology. This field pilot was injected with microorganisms and molasses from a centralized injection station in June 1990. Although microorganisms were injected only once per site, nutrient injection continued throughout the project life. All 19 injection wells were treated, and oil production was monitored from the 47 production wells. Injection pressures and volumes were monitored throughout the project. No operational problems were encountered. At the end of May 1993, oil production was improved by 19.6 %. Results from both projects are presented and the potential for microbial-enhanced waterflooding technology is evaluated.

  8. Tung FDG Test Facility. Phase 2, Pilot plant demonstration. Final report

    SciTech Connect

    1995-06-01

    The Tung FGD Process is a regenerative process which extracts SO{sub 2} from a scrubbing liquor into an organic medium using mixer-settlers followed by steam-stripping the SO{sub 2} off from the organic medium. For the process to operate satisfactorily, (1) the organic must be stable, (2) phase separation must be relatively fast, (3) crud (i.e. solids in-between two phases) must not form and (4) SO{sub 2} must be able to be stripped off from the organic medium readily. The demonstration confirmed that the first three conditions can be met satisfactorily. Much lower stripping efficiency was attained in the pilot plant demonstration than what was previously attained in a bench-scale demonstration. Engineering analysis showed that the pilot plant stripping column was scaled up from the bench-scale column incorrectly. A new scale-up criterion for stripping a relatively viscous liquid medium is proposed based upon pilot plant data.

  9. Understanding nutritional health in older adults. A pilot study.

    PubMed

    Callen, Bonnie

    2004-01-01

    A pilot study of adults ages 65 and older admitted to an acute care setting was conducted to compare nutritional risk as measured by hospital dieticians with two Nutrition Screening Initiative tools, the DETERMINE Your Nutritional Health Checklist and the Level I Screen, and to elicit from patients their own perceptions of nutritional health. Ten community-living older adults were interviewed. Although all 10 were at nutritional risk as measured by both hospital assessment and nutritional risk screening tools, none of these patients believed themselves to be at risk. One conclusion of this pilot is that interventions and education need to be tailored to the perceptions of targeted individuals.

  5. Pilot interaction with cockpit automation 2: An experimental study of pilots' model and awareness of the Flight Management System

    Sarter, Nadine B.; Woods, David D.

    1994-01-01

    Technological developments have made it possible to automate more and more functions on the commercial aviation flight deck and in other dynamic high-consequence domains. This increase in the degrees of freedom in design has shifted questions away from narrow technological feasibility. Many concerned groups, from designers and operators to regulators and researchers, have begun to ask questions about how we should use the possibilities afforded by technology skillfully to support and expand human performance. In this article, we report on an experimental study that addressed these questions by examining pilot interaction with the current generation of flight deck automation. Previous results on pilot-automation interaction derived from pilot surveys, incident reports, and training observations have produced a corpus of features and contexts in which human-machine coordination is likely to break down (e.g., automation surprises). We used these data to design a simulated flight scenario that contained a variety of probes designed to reveal pilots' mental model of one major component of flight deck automation: the Flight Management System (FMS). The events within the scenario were also designed to probe pilots' ability to apply their knowledge and understanding in specific flight contexts and to examine their ability to track the status and behavior of the automated system (mode awareness). Although pilots were able to 'make the system work' in standard situations, the results reveal a variety of latent problems in pilot-FMS interaction that can affect pilot performance in nonnormal time critical situations.

    2007-12-01

    We developed an innovative pilot studies program to foster partnerships between university researchers and agencies serving older people in New York City. The development of researchers willing to collaborate with frontline service agencies and service agencies ready to partner with researchers is critical for translating scientific research into evidence-based practice that benefits community-dwelling older adults. We adapted the traditional academic pilot studies model to include key features of community-based participatory research. In partnership with a network of 265 senior centers and service agencies, we built a multistep program to recruit and educate scientific investigators and agencies in the principles of community-based research and to fund research partnerships that fulfilled essential elements of research translation from university to community: scientific rigor, sensitivity to community needs, and applicability to frontline practice. We also developed an educational and monitoring infrastructure to support projects. Pilot studies programs developing community-based participatory research require an infrastructure that can supplement individual pilot investigator efforts with centralized resources to ensure proper implementation and dissemination of the research. The financial and time investment required to maintain programs such as those at the Cornell Institute for Translational Research on Aging, or CITRA, may be a barrier to establishing similar programs.

    Educators are integrating new technology into medical curriculum. The impact of newer technology on educational outcomes remains unclear. We aimed to determine if two pilot interventions, (1) introducing iPads into problem-based learning (PBL) sessions and (2) online tutoring would improve the educational experience of our learners. We voluntarily assigned 26 second-year medical students to iPad-based PBL sessions. Five students were assigned to Skype for exam remediation. We performed a mixed-method evaluation to determine efficacy. Pilot 1: Seventeen students completed a survey following their use of an iPad during the second-year PBL curriculum. Students noted the iPad allows for researching information in real time, annotating lecture notes, and viewing sharper images. Data indicate that iPads have value in medical education and are a positive addition to the curriculum. Pilot 2: Students agreed that online tutoring is at least or more effective than in-person tutoring. In our pilot studies, students experienced that iPads and Skype are beneficial in medical education and can be successfully employed in areas such as PBL and remediation. Educators should continue to further examine innovative opportunities for introducing technology into medical education. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    2016-01-01

    Digital textbooks are increasing in popularity, often resulting from the perception that students demand the use of technology in academics. However, few studies have been done on student perceptions of digital textbooks. A pilot study was conducted with students enrolled in a nursing research course; 123 nursing students participated. This study found that students overwhelmingly preferred print textbooks over digital textbooks. More research needs to be done before assuming students would prefer digital textbooks over print.

  16. Final report for the pilot-scale thermal treatment of Lower East Fork Poplar Creek floodplain soils

    SciTech Connect

    1994-09-01

    IT Corporation (IT) was contracted by Martin Marietta Energy Systems, Inc. (Energy Systems) to perform a pilot-scale demonstration of the effectiveness of thermal desorption as a remedial technology for removing mercury from the Lower East Fork Poplar Creek (LEFPC) floodplain soil. Previous laboratory studies by Energy Systems suggested that this technology could reduce mercury to very low levels. This pilot-scale demonstration study was initiated to verify on an engineering scale the performance of thermal desorption. This report includes the details of the demonstration study, including descriptions of experimental equipment and procedures, test conditions, sampling and analysis, quality assurance (QA), detailed test results, and an engineering assessment of a conceptual full-scale treatment facility. The specific project tasks addressed in this report were performed between October 1993 and June 1994. These tasks include soil receipt, preparation, and characterization; prepilot (bench-scale) desorption tests; front-end materials handling tests; pilot tests; back-end materials handling tests; residuals treatment; and engineering scale-up assessment.

    STS-99 Pilot Dominic Gorie appears to wave while the closeout crew in the White Room checks his launch and entry suit before he enters orbiter Endeavour. In the foreground is Chris Meinert, closeout chief. The White Room is an environmental chamber at the end of the orbiter access arm, on the fixed service structure, that provides entry to the orbiter crew compartment. STS-99, known as the Shuttle Radar Topography Mission (SRTM), will chart a new course to produce unrivaled 3-D images of the Earth's surface. The result of the Shuttle Radar Topography Mission could be close to 1 trillion measurements of the Earth's topography. Scheduled for liftoff at 12:30 p.m. EST, the mission is expected to last 11days, with Endeavour landing at KSC Tuesday, Feb. 22, at 4:36 p.m. EST. This is the 97th Shuttle flight and 14th for Shuttle Endeavour.

    2011-07-01

    Gas generation from the microbial degradation of the organic constituents of transuranic (TRU) waste under conditions expected in the Waste Isolation Pilot Plant (WIPP) was investigated. The biodegradation of mixed cellulosic materials and electron-beam irradiated plastic and rubber materials (polyethylene, polyvinylchloride, hypalon, leaded hypalon, and neoprene) was examined. We evaluated the effects of environmental variables such as initial atmosphere (air or nitrogen), water content (humid ({approx}70% relative humidity, RH) and brine inundated), and nutrient amendments (nitogen phosphate, yeast extract, and excess nitrate) on microbial gas generation. Total gas production was determined by pressure measurement and carbon dioxide (CO{sub 2}) and methane (CH{sub 4}) were analyzed by gas chromatography; cellulose degradation products in solution were analyzed by high-performance liquid chromatography. Microbial populations in the samples were determined by direct microscopy and molecular analysis. The results of this work are summarized.

  20. FMC limestone double-alkali flue gas desulfurization process: Pilot plant testing: Final report

    Troupe, J.S.; Shepley, D.C.

    1987-07-01

    This report documents pilot plant testing of a 3 MW (9500 acfm equivalent flue gas flow) FMC limestone double alkali FGD process operating on a slipstream of a commercial 420 MW boiler burning 3.5% sulfur coal. The report discusses the rationale behind EPRI's decision to participate in the testing aspects of this project, the history of the development of limestone double alkali technology, and the chemistry involved in this technology's operation. The largest part of the report is devoted to the results obtained from tests conducted during 65 days of pilot plant operation. All of the major raw and reduced operating and analytical data taken during testing are reproduced in the appendices to the report, along with quality assurance information to support the validity of the data obtained. The report discusses the test results in detail and presents technical observations regarding their implications. The FMC limestone double alkali FGD process (1) can consistently remove 92 to 93% of SO/sub 2/ from high-sulfur coal flue gas, (2) can achieve high limestone utilization and low soda ash losses, (3) produces a manageable waste filter cake, (4) is highly tolerant of upsets in limestone feed, soda ash makeup, and regeneration residence time, and (5) presents no unusual safety or environmental problems. The process, like conventional limestone scrubbing, shows some adverse effects of increasing soluble magnesium concentration on solids quality and requires a finely ground limestone feed material to achieve high limestone utilization. However, neither limestone grind nor magnesium concentration appears to affect SO/sub 2/ removal efficiency. The report suggests specific lines of future developmental work and future demonstration testing to enhance the attractiveness of this process to the electric utility industry. A bibliography of limestone double alkali literature is included. 3 refs., 25 figs., 4 tabs.

    Glider flying is a unique skill that requires pilots to control an aircraft at high speeds in three dimensions and amidst frequent full-body rotations. In the present study, we investigated the neural correlates of flying a glider using voxel-based morphometry. The comparison between gray matter densities of 15 glider pilots and a control group of 15 non-pilots exhibited significant gray matter density increases in left ventral premotor cortex, anterior cingulate cortex, and the supplementary eye field. We posit that the identified regions might be associated with cognitive and motor processes related to flying, such as joystick control, visuo-vestibular interaction, and oculomotor control.

    There are no reports on treatment of premenstrual syndrome with antidepressants, although depression is a common symptom of the syndrome. Eleven women who met DSM-III-R criteria for late luteal phase dysphoric disorder were treated with nortriptyline in an open pilot study after they failed to respond to placebo or another medication. Eight of 11 patients had a good therapeutic response. The efficacy of antidepressants in the treatment of premenstrual depression needs confirmation with double-blind studies.

  3. A remotely piloted aircraft system in major incident management: concept and pilot, feasibility study.

    PubMed

    2015-06-10

    Major incidents are complex, dynamic and bewildering task environments characterised by simultaneous, rapidly changing events, uncertainty and ill-structured problems. Efficient management, communication, decision-making and allocation of scarce medical resources at the chaotic scene of a major incident is challenging and often relies on sparse information and data. Communication and information sharing is primarily voice-to-voice through phone or radio on specified radio frequencies. Visual cues are abundant and difficult to communicate between teams and team members that are not co-located. The aim was to assess the concept and feasibility of using a remotely piloted aircraft (RPA) system to support remote sensing in simulated major incident exercises. We carried out an experimental, pilot feasibility study. A custom-made, remotely controlled, multirotor unmanned aerial vehicle with vertical take-off and landing was equipped with digital colour- and thermal imaging cameras, a laser beam, a mechanical gripper arm and an avalanche transceiver. We collected data in five simulated exercises: 1) mass casualty traffic accident, 2) mountain rescue, 3) avalanche with buried victims, 4) fisherman through thin ice and 5) search for casualties in the dark. The unmanned aerial vehicle was remotely controlled, with high precision, in close proximity to air space obstacles at very low levels without compromising work on the ground. Payload capacity and tolerance to wind and turbulence were limited. Aerial video, shot from different altitudes, and remote aerial avalanche beacon search were streamed wirelessly in real time to a monitor at a ground base. Electromagnetic interference disturbed signal reception in the ground monitor. A small remotely piloted aircraft can be used as an effective tool carrier, although limited by its payload capacity, wind speed and flight endurance.

    1990-04-01

    Guinea worm disease has been blamed for much disability and loss of productivity among farmers in Africa and South Asia. Many studies have tried to equate days lost in illness to monetary values. These attempts often overlook the process of disability in relation to farming patterns. This pilot effort uses a qualitative case study approach to learn about how Guinea worm can cause loss to farmers. Twenty in-depth interviews with affected farmers showed that their losses are related to the time of year they are affected by Guinea worm. Some crops with flexible planting times, e.g. cassava, may not be as affected. Duration of disability is another determining factor. Insights from this pilot study can be used to design more appropriate large-scale survey instruments and guide development of longitudinal research.

    Delirium is a common and severe complication among older hospitalized patients. The pathophysiology is poorly understood, but it has been suggested that inflammation and oxidative stress may play a role. The aim of this pilot study was to investigate levels of the neutrophil-lymphocyte ratio (NLR) - a marker of systemic inflammation and oxidative stress - in patients with and without delirium. This pilot study was performed within a retrospective chart review study that included acutely ill patients, 65 years and older, who were admitted to the ward of geriatrics of the Erasmus University Medical Center. All patients in whom the differential white blood cell (WBC) counts as well as the C-reactive protein (CRP) level were determined within 24 h after admission were included in the present study. Differences in NLR between patients with and without delirium were investigated using univariate analysis of variance, with adjustments for age, sex, comorbidities, CRP level, and total WBC count. Eighty-six patients were included. Thirteen patients were diagnosed with delirium. In adjusted models, higher mean NLR values were found in patients with, than in those without, delirium (9.10 vs 5.18, P=0.003). In this pilot study, we found increased NLR levels in patients with delirium. This finding might suggest that an inadequate response of the immune system and oxidative stress may play a role in the pathogenesis of delirium. Further studies are needed to confirm the association between NLR and delirium.

    Three naphthas with different initial and three naphthas with different final boiling points were compared by testing in a pilot reactor. The pilot reactor unit consisted of isothermal, once-through 200 cm{sup 2} reactors with on-line GCs for full product analysis and octane number determination. Octane numbers, reformate yields and composition, gas and hydrogen yields were measured as function of reaction temperature at 16 bar reaction pressure and a molar H{sub 2}/HC ratio of 4.23. Catalyst deactivation was studied over 2 weeks periods at high seventy conditions, i.e. 102.4 RON and a H{sub 2}/HC ratio of 2.2. Test results, with emphasis on the yields of benzene and other aromatics, hydrogen yields as well as catalyst deactivation, are presented.

    The Life Sciences, Microgravity Science and Spacelab Mission contains a number of human experiments directed toward identifying the functional, metabolic and neurological characteristics of muscle weakness and atrophy during space flight. To ensure the successful completion of the flight experiments, a ground-based pilot study, designed to mimic the flight protocols as closely as possible, was carried out in the head-down tilt bed rest model. This report records the rationales, procedures, preliminary results and estimated value of the pilot study, the first of its kind, for 12 of the 13 planned experiments in human research. The bed rest study was conducted in the Human Research Facility at Ames Research Center from July 11 - August 28, 1995. Eight healthy male volunteers performed the experiments before, during and after 17 days bed rest. The immediate purposes of this simulation were to integrate the experiments, provide data in a large enough sample for publication of results, enable investigators to review individual experiments in the framework of a multi-disciplinary study and relay the experience of the pilot study to the mission specialists prior to launch.

    2002-11-01

    A laboratory pilot study has been undertaken with the material that showed the most promise (high capacity and low pressure drop) based on the literature review and associated calculations. The best-performing air cleaner was a commercially available pleated filter that contained a thin layer of small activated carbon particles between two sheets of non-woven fibrous webbing. We will refer to this unit as the ''ozone filter'' although it is marketed for removal of volatile organic compounds (VOCs) from automobile passenger compartments. This pilot study strongly suggests that ozone air cleaning can be practical in commercial air handling systems; however, further tests are needed to assess air cleaner performance under a wider range of conditions.

    Neurofeedback (NFB) is an emerging treatment for children with autism spectrum disorder (ASD). This pilot study examined the feasibility of NFB for children with ASD. Ten children ages 7-12 with high functioning ASD and attention difficulties received a NFB attention training intervention. A standardized checklist captured feasibility, including focus during exercises and academic tasks, as well as off-task behaviors. Active behaviors and vocalizations were the most frequent off-task behaviors. Positive reinforcement and breaks including calm breathing exercises were the most common supports. Low motivation was associated with higher feasibility challenges, yet parental involvement and accommodations were helpful. This pilot study shows that it is feasible to conduct NFB sessions with children with high functioning autism and attention difficulties.

    1993-03-01

    A series of pilot-scale incineration tests were performed at the U.S. Environmental Protection Agency's (EPA's) Incineration Research Facility to evaluate the potential of incineration as an option to treat contaminated soils from the Drake Chemical Superfund site in Lock Haven, Pennsylvania. The soils at the Drake site are reported to be contaminated to varying degrees with various organic constituents and several hazardous constituent trace metals. The purpose of the test program was to evaluate the incinerability of selected site soils in terms of the destruction of contaminant organic constituents and the fate of contaminant trace metals. All tests were conducted in the rotary kiln incineration system at the IRF. Test results show that greater than 99.995 percent principal organic hazardous constituent (POHC) destruction and removal efficiencies (DRE) can be achieved at kiln exit gas temperatures of nominally 816 C (1,500 F) and 538 C (1,000 F). Complete soil decontamination of semivolatile organics was achieved; however, kiln ash levels of three volatile organic constituents remained comparable to soil levels.

    The project objectives were the development of a system to be used for exposing small laboratory animals to the respirable fraction of cotton dust found in a cotton mill, and testing an animal model of byssinosis which could be used to study the development of the disease in humans. This final report contains 10 published papers of the research at various stages of completion. A description of the cotton dust exposure system optimization techniques and measurements of the resulting improvements are noted in these articles. The final system developed used a large, modified, Pitt-3 cotton generator to expose up to 10 animals simultaneously to cotton dust in a Wahman stainless steel chamber. The acoustical powered generator, which was developed for the project to resuspend cotton dust has been very useful in resuspending other agricultural dusts. The development of an animal model for byssinosis involved verifying results of other investigators, developing and testing several new methods to evaluate pulmonary function in guinea pigs following acute cotton dust exposures, and modification of the cotton dust response using drug mediators.

    Introduction The purpose of this pilot study was to establish the feasibility of completing a future controlled trial of a multi-component cognitive behavioral therapy for insomnia program for military veterans with sleep disturbance. Method This was a single-arm feasibility and pilot study. Participants were United States post-9/11 veterans with service-connected injuries, university students, and had self-reported sleep disturbances. Restoring Effective Sleep Tranquility was a multi-component cognitive behavioral therapy for insomnia intervention consisting of seven sessions of group therapy and eight 1:1 sessions delivered by occupational therapists. Feasibility and pilot indicators were process, resources, management, and scientific, including pre–post-assessments of sleep difficulties, dysfunctional sleep beliefs, participation, and pain interference. Findings Indicators were supportive of feasibility, including reduced sleep difficulties (for example Medical Outcomes Study Sleep Measure [t = 3.29, p = .02]), reduced nightmares: t = 2.79, p = .03; fewer dysfunctional sleep beliefs: t = 3.63, p = .01, and greater ability to participate in social roles: t = –2.86, p = .03, along with trends towards improved satisfaction with participation and reduced pain interference. Conclusion The Restoring Effective Sleep Tranquility program may reduce sleep difficulties and improve participation in US veterans with service-connected injuries, and evidence indicates a controlled trial would be feasible to deliver.

    Airflow hazards such as vortices or low level wind shear have been identified as a primary contributing factor in many helicopter accidents. US Navy ships generate airwakes over their decks, creating potentially hazardous conditions for shipboard rotorcraft launch and recovery. Recent sensor developments may enable the delivery of airwake data to the cockpit, where visualizing the hazard data may improve safety and possibly extend ship/helicopter operational envelopes. A prototype flight-deck airflow hazard visualization system was implemented on a high-fidelity rotorcraft flight dynamics simulator. Experienced helicopter pilots, including pilots from all five branches of the military, participated in a usability study of the system. Data was collected both objectively from the simulator and subjectively from post-test questionnaires. Results of the data analysis are presented, demonstrating a reduction in crash rate and other trends that illustrate the potential of airflow hazard visualization to improve flight safety.

    A piloted, fixed-base simulation was conducted in 2006 to determine optimum rudder pedal force/feel characteristics for transport aircraft. As part of this research, an evaluation of four metrics for assessing rudder pedal characteristics previously presented in the literature was conducted. This evaluation was based upon the numerical handling qualities ratings assigned to a variety of pedal force/feel systems used in the simulation study. It is shown that, with the inclusion of a fifth metric, most of the rudder pedal force/feel system designs that were rated poorly by the evaluation pilots could be identified. It is suggested that these metrics form the basis of a certification requirement for transport aircraft.

    The aim of the research was to conduct a primary scoping study on the impact of air sealing between the foundation and the living space on radon transport reduction across the foundation-living space floor assembly. Fifteen homes in the Champaign, Illinois area participated in the study. These homes were instrumented for hourly continuous radon measurements and simultaneous temperature and humidity the foundation was improved. However, this improved isolation did not lead to significant reductions in radon concentration in the living space. Other factors such as outdoor temperature were shown to have an impact on radon concentration.

    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 many 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. Limitations of the study are also discussed. PMID:23818886

    This study evaluated a novel high-resolution breast-specific gamma camera (HRBGC) for the detection of suggestive breast lesions. Methods: Fifty patients (with 58 breast lesions) for whom a scintimammogram was clinically indicated were prospectively evaluated with a general-purpose gamma camera and a novel HRBGC prototype. The results of conventional and high-resolution nuclear studies were prospectively classified as negative (normal or benign) or positive (suggestive or malignant) by 2 radiologists who were unaware of the mammographic and histologic results. All of the included lesions were confirmed by pathology. Results: There were 30 benign and 28 malignant lesions. The sensitivity for detection of breast cancer was 64.3% (18/28) with the conventional camera and 78.6% (22/28) with the HRBGC. The specificity with both systems was 93.3% (28/30). For the 18 nonpalpable lesions, sensitivity was 55.5% (10/18) and 72.2% (13/18) with the general-purpose camera and the HRBGC, respectively. For lesions 1 cm, 7 of 15 were detected with the general-purpose camera and 10 of 15 with the HRBGC. Four lesions (median size, 8.5 mm) were detected only with the HRBGC and were missed by the conventional camera. Conclusion: Evaluation of indeterminate breast lesions with an HRBGC results in improved sensitivity for the detection of cancer, with greater improvement shown for nonpalpable and 1-cm lesions.

    The U.S. Department of Energy's Building America research team Partnership for Advanced Residential Retrofits conducted a primary scoping study on the impact of air sealing between the foundation and the living space on radon transport reduction across the foundation and living space floor assembly. Fifteen homes in the Champaign, Illinois, area participated in the study. These homes were instrumented for hourly continuous radon measurements and simultaneous temperature and humidity measurements. Blower door and zone pressure diagnostics were conducted at each house. The treatments consisted of using air-sealing foams at the underside of the floor that separated the living space from the foundation and providing duct sealing on the ductwork that is situated in the foundation area. The hypothesis was that air sealing the floor system that separated the foundation from the living space should better isolate the living space from the foundation; this isolation should lead to less radon entering the living space from the foundation. If the hypothesis had been proven, retrofit energy-efficiency programs may have chosen to adopt these isolation methods for enhanced radon protection to the living space.

    It is well established that sedentariness is the largest, preventable contributor to premature death, eclipsing smoking in recent years. One approach to reduce sedentariness is by using a treadmill desk to perform office work while walking at a low speed.We found an increased interest level when the treadmill desks were first introduced to LANL, but after a few months interest appeared to drop. It is possible that treadmill desk use was occurring, but subjects did not record their use. The treadmill desks will not be readily available for purchase by employees due to the study outcome. Additionally, conclusive changes in body measurements could not be performed due to lack of follow up by 58% of the participants.

    Based on the suboptimal research pathways that finally led to multicenter randomized clinical trials (MRCTs) of treadmill training with partial body weight support and of robotic assistive devices, strategically planned successive stages are proposed for pilot studies of novel rehabilitation interventions Stage 1, consideration-of-concept studies, drawn from animal experiments, theories, and observations, delineate the experimental intervention in a small convenience sample of participants, so the results must be interpreted with caution. Stage 2, development-of-concept pilots, should optimize the components of the intervention, settle on most appropriate outcome measures, and examine dose-response effects. A well-designed study that reveals no efficacy should be published to counterweight the confirmation bias of positive trials. Stage 3, demonstration-of-concept pilots, can build out from what has been learned to test at least 15 participants in each arm, using random assignment and blinded outcome measures. A control group should receive an active practice intervention aimed at the same primary outcome. A third arm could receive a substantially larger dose of the experimental therapy or a combinational intervention. If only 1 site performed this trial, a different investigative group should aim to reproduce positive outcomes based on the optimal dose of motor training. Stage 3 studies ought to suggest an effect size of 0.4 or higher, so that approximately 50 participants in each arm will be the number required to test for efficacy in a stage 4, proof-of-concept MRCT. By developing a consensus around acceptable and necessary practices for each stage, similar to CONSORT recommendations for the publication of phase III clinical trials, better quality pilot studies may move quickly into better designed and more successful MRCTs of experimental interventions.

  16. The Pakistan National Emergency Department Surveillance Study (Pak-NEDS): Introducing a pilot surveillance

    PubMed Central

    2015-01-01

    Background Evidence-based decision making is essential for appropriate prioritization and service provision by healthcare systems. Despite higher demands, data needs for this practice are not met in many cases in low- and middle-income countries because of underdeveloped sources, among other reasons. Emergency departments (EDs) provide an important channel for such information because of their strategic position within healthcare systems. This paper describes the design and pilot test of a national ED based surveillance system suitable for the Pakistani context. Methods The Pakistan National Emergency Department Surveillance Study (Pak-NEDS) was pilot tested in the emergency departments of seven major tertiary healthcare centres across the country. The Aga Khan University, Karachi, served as the coordinating centre. Key stakeholders and experts from all study institutes were involved in outlining data needs, development of the study questionnaire, and identification of appropriate surveillance mechanisms such as methods for data collection, monitoring, and quality assurance procedures. The surveillance system was operational between November 2010 and March 2011. Active surveillance was done 24 hours a day by data collectors hired and trained specifically for the study. All patients presenting to the study EDs were eligible participants. Over 270,000 cases were registered in the surveillance system over a period of four months. Coverage levels in the final month ranged from 91-100% and were highest in centres with the least volume of patients. Overall the coverage for the four months was 79% and crude operational costs were less than $0.20 per patient. Conclusions Pak-NEDS is the first multi-centre ED based surveillance system successfully piloted in a sample of major EDs having some of the highest patient volumes in Pakistan. Despite the challenges identified, our pilot shows that the system is flexible and scalable, and could potentially be adapted for many other

    The purpose of the present study was to assess the social skills of euthymic patients with bipolar disorder. A group of 25 outpatients with bipolar disorder type I were evaluated in comparison with a group of 31 healthy volunteers who were matched in terms of level of education, age, sex and intelligence. Both groups were assessed using a self-report questionnaire, the Brazilian Inventario de Habilidades Sociais (IHS, Social Skills Inventory). Two Wechsler Adult Intelligence Scale subtests (Picture Arrangement and Comprehension) were also used in order to assess subject ability to analyse social situations and to make judgements, respectively. Patients with bipolar disorder had lower IHS scores for the domains that assessed conversational skills/social self-confidence and social openness to new people/situations. Patients with anxiety disorders had high scores for the domain that assessed self-confidence in the expression of positive emotions. No differences were found between patients and controls in performance on the Wechsler Adult Intelligence Scale Picture Arrangement and Comprehension subtests. Euthymic patients with bipolar disorder present inhibited and overattentive behaviour in relation to other people and their environment. This behaviour might have a negative impact on their level of social functioning and quality of life.

    The Strategic Environmental Research and Development Program (SERDP) is supporting studies to develop and implement technologies for the safe, efficient, and environmentally sound disposal of obsolete munitions and propellants which are stored at various locations across the country. One proposed disposal technique is the open-air burning or detonation (OB/OD) of this material. Although OB/OD is viewed as an efficient and cost-effective method for reducing the inventory of unwanted munitions and propellants, questions regarding its safety and environmental impacts must be addressed. Since very large amounts of munitions and propellants must be consumed inexpensively in relatively short time periods and with the very restrictive Federal and State regulations on environmental issues, it is clear that traditional OB/OD procedures will not be acceptable and that it is necessary to develop modified or advanced OB/OD technology. The effectiveness and environmental impact of the OB/OD technology must be verified by experimental data and with validated numerical models for acceptance by Federal and State regulators. Specifically, technology must be developed and tested that minimizes toxic bum and detonation products the noise (peak pressure) and destructive effect (impulse) of the explosive blast generation and travel distance of shrapnel, and entrainment of dust. Three explosion attenuation scenarios are analyzed: Contained water, aqueous foams, and wet sand.

    We report a pilot study organized within the Consultative Committee for Amount of Substance (CCQM), in which the ozone reference standards of 23 institutes have been compared to one common reference, the BIPM ozone reference standard, in a series of bilateral comparisons carried out between July 2003 and February 2005. The BIPM, which maintains as its reference standard a standard reference photometer (SRP) developed by the National Institute of Standards and Technology (NIST, United States), served as pilot laboratory. A total of 25 instruments were compared to the common reference standard, either directly (16 comparisons) or via a transfer standard (9 comparisons). The comparisons were made over the ozone mole fraction range 0 nmol/mol to 500 nmol/mol. Two reference methods for measuring ozone mole fractions in synthetic air were compared, thanks to the participation of two institutes maintaining a gas-phase titration system with traceability of measurements to primary gas standards of NO and NO2, while the 23 other instruments were based on UV absorption. In the first instance, each comparison was characterized by the two parameters of a linear equation, as well as their related uncertainties, computed with generalized least-squares regression software. Analysis of these results using the Birge ratio indicated an underestimation of the uncertainties associated with the measurement results of some of the ozone standards, particularly the NIST SRPs. As a final result of the pilot study, the difference from the reference value (BIPM-SRP27 measurement result) and its related uncertainty were calculated for each ozone standard at the two nominal ozone mole fractions of 80 nmol/mol and 420 nmol/mol.

    The corrosion and gas-generation characteristics of four material types: low-carbon steel (the current waste packaging material for the Waste Isolation Pilot Plant), Cu-base and Ti-base (alternative packaging) materials, and Al-base (simulated waste) materials were determined in both the liquid and vapor phase of Brine A, a brine representative of an intergranular Salado Formation brine. Test environments consisted primarily of anoxic brine with overpressures of N{sub 2}, CO{sub 2}, H{sub 2}S, and H{sub 2}. Limited tests of low-carbon steel were also performed in simulated-backfill environments and in brine environments with pH values ranging from 3 to 11. Low-carbon steel reacted at a slow, measurable rate with anoxic brine, liberating H{sub 2} on an equimolar basis with Fe reacted. Presence of CO{sub 2} caused the initial reaction to proceed more rapidly, but CO{sub 2}-induced passivation stopped the reaction if the CO{sub 2} were present in sufficient quantities. Addition of H{sub 2}S to a CO{sub 2}-passivated system caused reversal of the passivation. Low-carbon steel immersed in brine with H{sub 2}S showed no reaction, apparently because of passivation of the steel by formation of FeS. Addition of CO{sub 2} to an H{sub 2}S-passivated system did not reverse the passivation. Cu- and Ti-base materials showed essentially no corrosion when exposed to brine and overpressures of N{sub 2}, CO{sub 2}, and H{sub 2}S except for the rapid and complete reaction between Cu-base materials and H{sub 2}S. The Al-base materials reacted at approximately the same rate as low-carbon steel when immersed in anoxic Brine A; considerably more rapidly in the presence of CO{sub 2} or H{sub 2}S; and much more rapidly when iron was present in the system as a brine contaminant. High-purity Al was much more susceptible to corrosion than the 6061 alloy. No significant reaction took place on any material in any environment in the vapor-phase exposures.

    Lodestar has carried out a vigorous research program in the areas of rf, edge plasma and divertor physics, with emphasis largely geared towards improving the understanding and performance of ion-cyclotron heating and current drive (ICRF) systems. Additionally, a research program in the field of edge plasma and divertor modeling was initiated. Theoretical work on high power rf sheath formation for multi-strap rf arrays was developed and benchmarked against recent experimental data from the new JET A2 antennas. Sophisticated modeling tools were employed to understand the sheath formation taking into account realistic three-dimensional antenna geometry. A novel physics explanation of an observed anomaly in the low power loading of antennas was applied to qualitatively interpret data on DIII-D in terms of rf sheaths, and potential applications of the idea to develop a near-field sheath diagnostic were explored. Other rf-wave related topics were also investigated. Full wave ICRF modeling studies were carried out in support of ongoing and planned tokamaks experiments, including the investigation of low frequency plasma heating and current drive regimes for IGNITOR. In a cross-disciplinary study involving both MHD and ICRF physics, ponderomotive feedback stabilization by rf was investigated as a potential means of controlling external kink mode disruptions. In another study, the instability of the ion hybrid wave (IHW) in the presence of fusion alpha particles was studied. In the field of edge plasma and divertor modeling studies, Lodestar began the development of a theory of generalized ballooning and sheath instabilities in the scrape off layer (SOL) of divertor tokamaks. A detailed summary of the technical progress in these areas during the contract period is included, as well as where references to published work can be found. A separate listing of publications, meeting abstracts, and other presentations is also given at the end of this final report.

  2. Pharmacogenetics of Ketamine-Induced Emergence Phenomena: A Pilot Study.

    Up to 55% of patients who are administered ketamine experience an emergence phenomena (EP) that closely mimics schizophrenia and increases their risk of injury; however, to date, no studies have investigated genetic association of ketamine-induced EP in healthy patients. The aim of the study was to investigate the feasibility and sample sizes required to explore the relationship between CYP2B6*6 and GRIN2B single-nucleotide polymorphisms and ketamine-induced EP. This cross-sectional, pharmacogenetic candidate, gene pilot study recruited 75 patients having minor elective outpatient surgeries. EP was measured with the Clinician Administered Dissociative State Scale. Genetic association of CYP2B6*6 and GRIN2B (rs1019385 and rs1806191) single-nucleotide polymorphisms and ketamine-induced EP occurrence and severity were tested using logistic and linear regression. Forty-seven patients (63%) received ketamine and were genotyped, and 40% of them experienced EP. Occurrence and severity of EP were not associated with CYP2B6*6 or GRIN2B (p > .10). Exploratory analysis of nongenotype models containing age, ketamine dose, duration of anesthesia, and time from ketamine administration to assessment for EP significantly predicted EP occurrence (p = .001) and severity (p = .007). This pilot study demonstrates feasibility for implementing a pharmacogenetic study in a clinical setting, and we estimate that between 380 and 570 cases will be needed to adequately power future genetic association studies. Younger age, higher dose, and longer duration of anesthesia significantly predicted EP occurrence and severity among our pilot sample. Although the small sample size limited our ability to demonstrate significant genotype differences, we generated effect sizes, sample size estimates, and nongenetic covariates information in order to support future pharmacogenetic study design for evaluating this adverse event.

    During the last 15 years, a substantial number of population-based, clinical, laboratory, and animal studies have been published that reported findings on the relationship between periodontal disease and cardiovascular disease. The Periodontitis and Vascular Events (PAVE) pilot study was conducted to investigate the feasibility of a randomized secondary prevention trial to test whether treatment of periodontal disease reduces the risk for cardiovascular disease. This article describes the occurrence of adverse events during the pilot study. The PAVE pilot study was a multicenter, randomized trial comparing periodontal therapy to community dental care. Baseline and follow-up clinic visits included a periodontal examination; blood, subgingival plaque, and crevicular fluid specimen collection; and medical and dental histories. Telephone follow-up contacts were scheduled to occur 3 months after randomization and every 6 months thereafter to assess adverse events or endpoints. Cardiovascular adverse events occurred with similar frequency (23 versus 24 [P = 0.85] in the community control and the treatment groups, respectively). There were 15 serious adverse events (SAEs) with a non-significantly higher percentage occurring in the community care group (6.6% versus 3.3%; P = 0.19). A time-to-event analysis of patterns of SAEs indicated that subjects in the periodontal therapy group tended to be less likely to experience an SAE over the entire 25 months of the study. For those individuals who remained in the study, it appears that provision of periodontal scaling and root planing treatment to individuals with heart disease resulted in a similar pattern of adverse events as seen in the community care group, which also received some treatment.

    The objective of the Automated Diagnostics Scoping Study was to investigate the needs for diagnostics in building operation and to examine some of the current technologies in automated diagnostics that can address these needs. The study was conducted in two parts. In the needs analysis, the authors interviewed facility managers and engineers at five building sites. In the technology survey, they collected published information on automated diagnostic technologies in commercial and military applications as well as on technologies currently under research. The following describe key areas that the authors identify for the research, development, and deployment of automated diagnostic technologies: tools and techniques to aid diagnosis during building commissioning, especially those that address issues arising from integrating building systems and diagnosing multiple simultaneous faults; technologies to aid diagnosis for systems and components that are unmonitored or unalarmed; automated capabilities to assist cause-and-effect exploration during diagnosis; inexpensive, reliable sensors, especially those that expand the current range of sensory input; technologies that aid predictive diagnosis through trend analysis; integration of simulation and optimization tools with building automation systems to optimize control strategies and energy performance; integration of diagnostic, control, and preventive maintenance technologies. By relating existing technologies to perceived and actual needs, the authors reached some conclusions about the opportunities for automated diagnostics in building operation. Some of a building operator`s needs can be satisfied by off-the-shelf hardware and software. Other needs are not so easily satisfied, suggesting directions for future research. Their conclusions and suggestions are offered in the final section of this study.

    Between 2010 and 2012 the Eastern Interconnection Planning Collaborative (EIPC) conducted a major long-term resource and transmission study of the Eastern Interconnection (EI). With guidance from a Stakeholder Steering Committee (SSC) that included representatives from the Eastern Interconnection States Planning Council (EISPC) among others, the project was conducted in two phases. Phase 1 involved a long-term capacity expansion analysis that involved creation of eight major futures plus 72 sensitivities. Three scenarios were selected for more extensive transmission- focused evaluation in Phase 2. Five power flow analyses, nine production cost model runs (including six sensitivities), and three capital cost estimations were developed during this second phase. The results from Phase 1 and 2 provided a wealth of data that could be examined further to address energy-related questions. A list of 14 topics was developed for further analysis. This paper brings together the earlier interim reports of the first 13 topics plus one additional topic into a single final report.

A detailed description of this add-on study can be found in the peer reviewed research protocol entitled “An EPA Pilot Study Evaluating Personal, Housing, and Community Factors Influencing Children’s Potential Exposures to Indoor Contaminants at Various Lifestages –Research Protocol” 1. Briefly, the Centers for Disease Control and Prevention’s (CDC) Green Housing Study (GHS) follows changes in environmental measurements [pesticides, volatile organic compounds (VOCs), particulate matter (i.e., PM2.5 and 1.0), indoor allergens, and fungi] in both U.S. Department of Housing and Urban Development (HUD) green-renovated and comparison (no renovation) homes and relates these changes to asthma morbidity in children ages 7-12 years. Green-renovations include (but are not limited to) use of low VOC materials, use of energy efficient appliances, and integrated pest management. The EPA has leveraged this opportunity to collect additional multimedia measurements and questionnaire data from the index children actively participating in the GHS and a sibling in order to characterize personal, housing, and community factors. The purpose of this document is to publish the methodology EPA used for a specific study for reference and use by other scientists both within the Agency

    The technical and economic feasibility of applying bottoming cycles to the prime movers that drive the compressors of natural gas pipelines was studied. These bottoming cycles convert some of the waste heat from the exhaust gas of the prime movers into shaft power and conserve gas. Three typical compressor station sites were selected, each on a different pipeline. Although the prime movers were different, they were similar enough in exhaust gas flow rate and temperature that a single bottoming cycle system could be designed, with some modifications, for all three sites. Preliminary design included selection of the bottoming cycle working fluid, optimization of the cycle, and design of the components, such as turbine, vapor generator and condensers. Installation drawings were made and hardware and installation costs were estimated. The results of the economic assessment of retrofitting bottoming cycle systems on the three selected sites indicated that profitability was strongly dependent upon the site-specific installation costs, how the energy was used and the yearly utilization of the apparatus. The study indicated that the bottoming cycles are a competitive investment alternative for certain applications for the pipeline industry. Bottoming cycles are technically feasible. It was concluded that proper design and operating practices would reduce the environmental and safety hazards to acceptable levels. The amount of gas that could be saved through the year 2000 by the adoption of bottoming cycles for two different supply projections was estimated as from 0.296 trillion ft/sup 3/ for a low supply projection to 0.734 trillion ft/sup 3/ for a high supply projection. The potential market for bottoming cycle equipment for the two supply projections varied from 170 to 500 units of varying size. Finally, a demonstration program plan was developed.

    Although debriefing in simulation settings is routine in nursing education, debriefing does not routinely take place in clinical settings with nursing students after a patient has died. This pilot study sought to explore nursing students' perceptions of their first experience with the death of a patient. Students reported emotional distress and feelings of inadequacy with regard to communicating with and supporting the family of the dying patient. Only half the students sampled reported debriefing by their clinical instructor or staff. Nurse educators must include debriefing and student support following a patient death in the clinical setting.

    In the past decade, colleges and universities have seen a large increase in the number of students referred for the violation of alcohol policies. Stepped care assigns individuals to different levels of care according to treatment response, thereby maximizing efficiency. This pilot study implemented stepped care with students mandated to attend an alcohol program at a private northeastern university. High retention rates and participant satisfaction ratings suggest the promise of implementing stepped care with this population. Considerations for future applications of stepped care with mandated students are discussed. PMID:17453615

    With a growing number of low-income patients developing Congestive Heart Failure in urban Denver, accessible and affordable solutions are needed to provide home management options. A multidisciplinary team evaluated currently available options for telemonitoring and developed a solution for an initial pilot study. This system is currently used in the Denver Metro area (Colorado) for 44 CHF patients. Preliminary results show this approach is effective and has reduced the patients' average length of stay at the hospital compared to historical data and control patients who do not use a remote monitoring system.

    Individuals with schizophrenia demonstrate deficits in divergent thinking. This ability is indispensable for generating creative solutions and navigating the complexities of social interactions. In a pilot study, seventeen stable schizophrenia outpatients were randomly assigned to a training program for divergent thinking or a control program on convergent thinking. After eight weeks of training, participants in the divergent thinking program had significantly greater improvements on measures of idea fluency, negative symptoms, and interpersonal relations than did participants receiving the control program. These preliminary results suggest that interventions for divergent thinking in schizophrenia may lead to improvements in patients' social functioning.

    In this pilot study, 20 HIV-infected children, 6 to 12 years of age, were randomly assigned into therapeutic touch (TT) and mimic TT groups. The effectiveness of TT in reducing anxiety was evaluated. The self-report measure, the A-State Anxiety subscale of the Spielberger State-Trait Anxiety Inventory For Children, was administered before and immediately after interventions. As predicted, the TT intervention resulted in lower overall mean anxiety scores, whereas the mimic TT did not. These findings provide preliminary support for the use of TT in reducing the state anxiety of children with HIV infection.

    Health care organizations are developing Web-based portals to provide patient access to personal health information and enhance patient-provider communication. This pilot study investigates two navigation models (“serial” and “menu-driven”) for improving access to education materials available through a portal. There was a trend toward greater user satisfaction with the menu-driven model. Model preference was influenced by frequency of Web use. Results should aid in the improvement of existing portals and in the development of new ones. PMID:16779179

    Women and families are the fastest growing segment of the homeless population. Negative attitudes of nurses toward homeless women are a major barrier to homeless women seeking health care. This cross-sectional, mixed-methods pilot study, conducted primarily by nurses, tested the Mantram Repetition Program for the first time with 29 homeless women. The Mantram Repetition Program is a spiritually based skills training that teaches mantram (sacred word) repetition as a cost-effective, personalized, portable, and focused strategy for reducing stress and improving well-being. For the cross-sectional, pretest-posttest design portion of the study, the hypothesis that at least half of the homeless women would repeat their mantram at least once a day was supported with 88% of the women repeating their mantram 1 week later. The qualitative portion of this study using phenomenology explored the women's thoughts on mantram week 2. Themes of mantram repetition, mantram benefits, and being cared for emerged. This groundbreaking, interventional, mixed-methods pilot study fills a gap in interventional homeless research.

    Iragüen, D., Urcelay, S., San Martín, B. Pharmacovigilance in veterinary medicine in Chile: a pilot study. J. vet. Pharmacol. Therap.34, 108-115. In Chile, there is no present government policy to survey and analyse adverse drug reactions (ADRs) in the field of veterinary medicine. The intent of this study is to assess, for the first time, ADR frequency in treated animals. To this purpose, a 6-month period pilot study based on WHO recommendations was conducted to monitor ADRs in cats and dogs for frequently used drugs and common labelled signs. Of a total of 149 detected ADRs, 29 (6 in cats and 23 in dogs) were notified by means of ADR report forms, while the rest was identified after reviewing patient clinical records, thus evidencing strong under-reporting problems. More than 70% of ADRs were related to antimicrobials, vaccines and tranquilizers. In dogs, there was a significant effect on ADRs' presentation when acepromazine, amoxicillin, carprofen, ivermectin, sextuple vaccine (polyvalent vaccine that confers immunity against canine distemper virus, canine parvovirus, Leptospira canicola, L. icterohemmoragiae, canine adenovirus type 2 and canine parainfluenza virus) and phytomenadione (subcutaneous injection) were administered. In the case of cats, a significant influence on ADRs was detected when acepromazine, amoxicillin or vitamin K was administered. Present results suggest the need for a pharmacovigilance programme in veterinary medicine for timely ADR-presenting drug detection and drug safety improvement.

  18. The effectiveness of auxiliary prescription labels: a pilot study.

    PubMed

    1983-03-01

    Affixed auxiliary prescription labels are widely used in the practice of pharmacy because they supposedly provide the patient with pertinent information that is not contained within the prescription signature. Yet, whether the labels are effective is not known, nor is it known whether the label's elements, such as color, form, and logo, affect perception of the written text. Sound scientific analyses of these questions are limited. Therefore, a pilot study involving a series of experiments was designed to determine whether individual perception of pertinent information is affected by the use of affixed auxiliary prescription labels. The second objective of this study was to evaluate how color and logo differences affected perception of the label's written text. Participants were selected for the experiments after being screened for color blindness, corrected vision, and, in some cases, previous pharmacy employment. Subjects viewed labels affixed to prescription vials via a two-channel tachistoscope. The tachistoscopic methodology measured perception, and its accuracy was verified through a forced-choice instrument. Results from the pilot study were threefold: (1) a sound scientific analysis found affixed auxiliary labels to be effective, (2) significant variance could be attributed to both individual and subject differences, and (3) the unique effects of color and logo could not be determined.

    Prosthetic rehabilitation is an extremely challenging task in extreme resorption cases of the maxillary denture-bearing area. Reducing the weight of a maxillary obturator has been seen as beneficial. But whether reducing the weight of conventional complete denture also increases retention or not, is still very dubious. The aim of this pilot study was to determine the effect of maxillary denture weight on denture retention and stability. For this study, a total of 10 patients were considered for the pilot study (06 female and 04 male) with an average age of 70 y. Each patient was provided with two sets of maxillary complete dentures, one hollow labeled as A and one conventional maxillary denture labeled as B. It was shown that mean values for retention using MKIS for retention for hollow dentures (A) was 7.8 and for conventional dentures (B) it was 8.2 and the stability for maxillary dentures was more with conventional dentures (B) than hollow maxillary dentures (A) and it was significant as p-value was 0.015 (p<.1). The denture retention and stability, chewing and comfort values of conventional dentures and hollow dentures were slightly better for conventional dentures.

    1994-09-01

    Anatomical features of the intercondylar roof with respect to the native anterior cruciate ligament and proposed substitute ligament attachment sites in anterior cruciate ligament reconstructive surgery were investigated. Using cadaveric knees and K wires, radiographs were obtained with markers placed on the roof and the tibial and femoral attachment sites. In the knees studied, the intercondylar roof was V shaped with distinct anterior and posterior limbs. The posterior limb corresponded to the radiographic line commonly called Blumensaat's line. The anterior limb was oriented 25 degrees more vertical than the posterior limb and impinged on the anterior cruciate ligament in extension. In this pilot study, estimates of the degree of impingement in full extension were made by drawing lines representative of 10-mm grafts at selected sites on lateral radiographs. A graft placed at the central portion of the native femoral site to the normal tibial site did not impinge, while a graft placed at the traditional femoral site to an anteromedial tibial site impinged as much as 8 mm throughout its entire extent. This pilot study presents preliminary, provocative information suggesting that the intercondylar roof is actually V shaped and that substitute ligaments placed at attachment sites commonly used today may impinge over most of their length.

  1. Homeopathic Secretin in autism: a clinical pilot study.

    Robinson, T W

    2001-04-01

    Autism is a condition characterised by impairments of social communication, social interaction and social imagination. The exact aetiology of autism is unknown but some autistic features have been explained by the 'opioid excess theory' in which excess brain peptide levels have a morphine-like activity. Reduction of peptide levels by administration of the duodenal enzyme Secretin has been found to improve social and language skills in autistic patients. Homeopathic Secretin has been said to produce similar effects. A pilot study was undertaken to study these effects by administration of Secretin to a group of autistic patients. Weekly assessment for 12 weeks was performed by the patients' care workers. Statistical analysis of the mean pre-treatment results compared with the mean treatment results suggested a worsening in the autistic symptoms during treatment. Discussion with the care workers revealed changes and some improvements that were not recordable on the scoring system. Further research into Secretin treatment of autism using a more detailed and customized scoring system would be justified. Following this pilot study a randomised controlled trial of Secretin vs placebo would be appropriate.

    Background Temporomandibular disorders (TMDs) are by far the most predominant condition affecting the temporomandibular joint (TMJ), however many patients have mild self-limiting symptoms and should not be referred for specialist care. The aim of this pilot study was to develop a simple, cost-effective management programme for TMDs using CD-ROM. 41 patients (age 18–70) participated in this study, patients were divided into three groups: the 1st group were involved in an attention placebo CD-ROM (contain anatomical information about the temporomandibular system), the 2nd group received information on CD-ROM designed to increase their control and self efficacy, while the 3rd group received the same programme of the 2nd group added to it an introduction to self-relaxing techniques followed by audio tape of progressive muscle relaxation exercises. Each of the groups was asked to complete a number of questionnaires on the day of initial consultation and six weeks afterwards. Results The two experimental groups (2nd & 3rd) were equally effective in reducing pain, disability and distress, and both were more effective than the attention placebo group (1st), however the experimental groups appeared to have improved at follow-up relative to the placebo-group in terms of disability, pain and depressed mood. Conclusion This pilot study demonstrates the feasibility and acceptability of the design. A full, randomized, controlled trial is required to confirm the efficacy of the interventions developed here.

    This report describes a pilot study conducted at the INEL to dismantle lead-lined casks and shielding devices, separate the radiologically contaminated and hazardous materials, and recycle resultant scrap lead. The facility areas where the work was performed, dismantlement methods, and process equipment are described. Issues and results associated with recycling the lead as a free-released scrap metal are presented and discussed. Data and results from the pilot study are summarized and presented. The study concluded that cask dismantlement at the INEL can be performed as a legitimate recycling activity for scrap lead. Ninety-one percent of the lead recovered passed free-release criteria. The value of the 50,375 lb of recovered lead is approximately $0.45/lb. Resultant waste streams can be satisfactorily treated and disposed. Only very low levels of bulk radiological contamination (47 picocuries/gram of 137 Cs and 3.2 picocuries/gram of {sup 6O}Co) were detected in the lead rejected for free release.

    A pilot study was conducted of a personalized feedback intervention for problem gamblers. Respondents (N=61) were recruited from an ongoing gambling research study to take part in another study to help us "develop and evaluate self-help materials for gamblers." Respondents were randomly assigned to receive a personalized feedback summary or to a waiting list control. At 3-month follow-up (80.3% follow-up rate, N=49), after controlling for baseline demographic characteristics and gambling severity, respondents in the feedback condition displayed some evidence that they were spending less money on gambling than those in the control condition. Further, ratings of the usefulness of the feedback summary were positive and most recipients (96%) recommended that they be made available to other gamblers interested in evaluating or modifying their gambling. Given these promising pilot results, a full-scale evaluation of these personalized feedback materials would appear justified. An online version of the intervention is now also available at www.CheckYourGambling.net.

    Scour around bridges is a serious problem on many rivers; bridge failure often is attributed to undermining of piers or abutments by scour. A pilot study was made at four bridge sites in Colorado to develop and test guidelines for collecting scour data onsite during high flows. These guidelines potentially could be used to conduct bridge-scour studies or to establish a nationwide bridge-scour data collection program in conjunction with normal high-flow measurements. The methods tested are intended to be compatible with equipment and procedures commonly used in the U.S. Geological Survey streamflow-gaging program. Thirteen scour-prediction equations were evaluated using data collected during this study. Two alternative approaches for future, proposed scour studies are indicated. The type of approach selected would depend on the objectives of the scour study and the flow conditions in the study area. (USGS)

    In planning for a large-scale multicenter trial to evaluate the effect of acupuncture for the treatment of lateral elbow pain, a pilot study was conducted. This was a prospective, investigator- and patient-blinded, nonrandomized, placebo controlled trial. Subjects were evaluated at baseline, before fourth, seventh, and ninth treatment, and at a two-week posttreatment follow-up. The treatment group received unilateral acupuncture at LI 10 and LI 11 at the affected side with manual needle manipulation; the control group received sham-laser acupuncture at the same acupoints. Measures included (i) disabilities of the arm, shoulder, and hand (DASH) questionnaire, (ii) pain-free grip strength (PFGS), and (iii) a visual analogue scale (VAS) for pain. Significant differences in DASH score, PFGS, and VAS between treatment and control group were found at the ninth treatment (n = 20 for each group, P < 0.05). Only DASH showed significant differences compared to the control for all the measurement time points after treatment commenced and appears to be a sensitive and appropriate primary outcome measure for the future multisite trial. Results from this pilot study provided relevant information about treatment efficacy, credibility of control treatment, and sensitivity of different outcome measures for the planning of the future trial.

    This pilot study examined the use of Reiki prior to colonoscopy to reduce anxiety and minimize intraprocedure medications compared with usual care. A prospective, nonblinded, partially randomized patient preference design was employed using 21 subjects undergoing colonoscopy for the first time. Symptoms of anxiety and pain were assessed using a Likert-type scale. Between-group differences were assessed using chi-square analyses and analysis of variance. There were no differences between the control (n = 10) and experimental (n = 11) groups on age (mean = 58 years, SD = 8.5) and gender (53% women). The experimental group had higher anxiety (4.5 vs. 2.6, p = .03) and pain (0.8 vs. 0.2, p = .42) scores prior to colonoscopy. The Reiki intervention reduced mean heart rate (-9 beats/minute), systolic blood pressure (-10 mmHg), diastolic blood pressure (-4 mmHg), and respirations (-3 breaths/minute). There were no between-group differences on intraprocedure medication use or postprocedure physiologic measures. Although the experimental group patients had more symptoms, they did not require additional pain medication during the procedure, suggesting that (1) anxious people may benefit from an adjunctive therapy; (2) anxiety and pain are decreased by Reiki therapy for patients undergoing colonoscopy, and (3) additional intraprocedure pain medication may not be needed for colonoscopy patients receiving Reiki therapy. This pilot study provided important insights in preparation for a rigorous, randomized, controlled clinical trial.

    To investigate the association between dental caries and early childhood development in 3-year-olds from Talca, Chile. A pilot study with a convenience sample of 3-year-olds from Talca (n = 39) who attend public healthcare centers. Child development was measured by the Psychomotor Development Index (PDI), a screening tool used nationally among pre-school children to assess language development, fine motor skills and coordination areas. Dental caries prevalence was evaluated by decayed, missing, filled teeth (DFMT) and decayed, missing, filled tooth surfaces (DFMS) ceo-d and ceo-s indexes. The children were divided into two groups according to the PDIscore: those with a score of 40 or more were considered developmentally normal (n = 32), and those with a score below 40 were considered as having impaired development (n = 7). The severity of caries (DMFT) was negatively correlated with PDI (r = -0.82), and children with the lowest TEPSI score had the highest DFMT values. The average DMFT in children with normal development was 1.31, and 3.57 for those with impaired development. This pilot study indicates that the severity of dental caries is correlated with early childhood development. Copyright © 2015. Publicado por Elsevier España, S.L.U.

    There is an increasing body of research on what kind of ethical challenges health care professionals experience regarding the quality of care. In the Netherlands the Dutch Health Care Inspectorate is responsible for monitoring and regulating the quality of health care. No research exists on what kind of ethical challenges inspectors experience during the regulation process itself. In a pilot study we used moral case deliberation as method in order to reflect upon inspectors' ethical challenges. The objective of this paper is to give an overview of the ethical challenges which health care inspectors encounter in their daily work. A thematic qualitative analysis was performed on cases (n = 69) that were collected from health care inspectors in a moral case deliberation pilot study. Eight themes were identified in health care regulation. These can be divided in two categories: work content and internal collaboration. The work of the health care inspectorate is morally loaded and our recommendation is that some form of ethics support is provided for health care inspectors.

    The goal of the Environmental Monitoring and Assessment Program - Wetlands (EMAP-Wetlands) Southeastern Pilot Study is to develop field indicators of salt marsh condition. These indicators are of four general types: (1) vegetation; (2) hydrology; (3) soil parameters; and (4) soil constituents. Field measurements and samples will be collected during late summer/early fall in 1991 and will be analyzed to identify which indicators and measurements best delineate salt marsh in good condition from that in impaired condition. Thus the project will involve field work, laboratory analysis, and data analysis. Results from this project will be used to establish criteria and parameters for long-term monitoring and assessment of salt marshes, particularly those parameters that may serve as indicators of healthy salt marsh and deteriorated salt marsh. Since EMAP-Wetlands-Southeastern is a pilot study, the measurement criteria will be evaluated as one of the project goals. Of concern will be how well the standardized sampling methods performed in actual field conditions, and which of these methods can be used to assess and characterize salt marshes.

    2012-04-01

    In a world where funding is limited, training for healthcare professionals is turning more and more to distance learning in an effort to maintain a knowledgeable and skilled work force. In 2010, Cicatelli Associates, Inc. began exploring the feasibility of using games and virtual worlds as an alternative means to teach skills-training in a distance-learning environment. The pilot study was conducted with six individuals familiar with general counseling and communication skills used by the healthcare industry to promote behavior change. Participants reported that the venue, although challenging at first, showed great potential for use with healthcare providers, as it allowed for more interaction and activities than traditional Webinars. However, there are significant limitations that must be overcome in order for this healthcare training modality to be utilized on a large scale. These limitations included a lack of microgestures and issues regarding the technology being used. In spite of the limitations, however, the potential use of virtual worlds for the training of healthcare providers exists and should be researched further. This article discusses the need and intended benefits of virtual world training as well as the results and conclusions of the pilot study.

    The aim was to develop an Information Gathering Schedule (IGS) relevant to forensic psychiatric nursing in order to establish the perceived differences in the three levels of security, high, medium and low. Perceived differences in the role constructs of forensic psychiatric nursing is said to exist but the evidence is qualitative or anecdotal. This paper sets out a pilot study beginning in 2004 relating to the development of two rating scales for inclusion into an IGS to acquire data on the role constructs of nurses working in these environments. Following a thematic analysis from the literature two sets of binary frameworks were constructed and a number of questions/statements relating to them were tested. The Thurstone Scaling test was applied to compute medians resulting in a reduction to 48 and 20 items for each respective framework. Two 7-point Likert scales were constructed and test-retest procedures were applied on a sample population of forensic psychiatric nurses. Student's t-test was conducted on the data and the results suggest that the IGS is now suitable for application on a larger study. The IGS was piloted on a small sample of forensic psychiatric nurses. The two scales were validated to coefficient values ranging from 0.7 to 0.9. Amendments were made and the IGS was considered acceptable.

    1985-01-01

    Piloted simulation studies of cockpit traffic display concepts require the development of representative traffic scenarios. With the exception of specific aircraft interaction issues, most research questions can be addressed using traffic scenarios consisting of prerecorded aircraft movements merged together to form a desired traffic pattern. Prerecorded traffic scenarios have distinct research advantages, allowing control of traffic encounters with repeatability of scenarios between different test subjects. A technique is described for generation of prerecorded jet transport traffic scenarios suitable for use in piloted simulation studies. Individual flight profiles for the aircraft in the scenario are created interactively with a computer program designed specifically for this purpose. The profiles are then time-correlated and merged into a complete scenario. This technique was used to create traffic scenarios for the Denver, Colorado area with operations centered at Stapleton International Airport. Traffic scenarios for other areas may also be created using this technique, with appropriate modifications made to the navigation fix locations contained in the flight profile generation program.

    BACKGROUND: Current guidelines recommend that colonoscopic colorectal cancer screening be undertaken every 10 years after the age of 50 years. However, because the procedure does not meet criteria that promote screening uptake, patient satisfaction with colonoscopy may encourage repeat screening. OBJECTIVE: To systematically review the literature and conduct a pilot study of patient satisfaction with the colonoscopy experience. METHODS: All cohort studies from January 1997 to August 2008 in the MEDLINE database that measured either patient satisfaction with colonoscopy, patient willingness to return for colonoscopy under the same conditions or patient preference for colonoscopy compared with other large bowel procedures were identified. The search was supplemented by journal citation lists in the retrieved articles. RESULTS: Of the 29 studies identified, 15 met the inclusion criteria. Consistently, the vast majority of patients (approximately 95%) were very satisfied with their colonoscopy experience. Patient satisfaction was similar for screening and nonscreening colonoscopy. Patient willingness to return for the procedure ranged from 73% to 100%. Of the five studies that examined modality preference, three studies reported the majority of patients preferred colonography to colonoscopy and two studies reported the reverse. Our pilot study findings mirrored those of other studies that were conducted in the United States. The major limitation of the included studies was that patients who were most dissatisfied may have gone elsewhere to have their colonoscopy. CONCLUSIONS: Patients were very satisfied with colonoscopy. The majority were willing to return for repeat testing under the same conditions, and colonoscopy was not preferred over other modalities. However, studies were limited by methodological shortcomings. PMID:19319384

  1. Final report from VFL technologies for the pilot-scale thermal treatment of Lower East Fork Poplar Creek floodplain soils

    SciTech Connect

    1994-09-01

    The Lower East Fork Poplar Creek (LEFPC) extends fourteen (14) miles through Oak Ridge, TN. The Creek sediments and surrounding floodplain soils are contaminated with mercury compounds. This project involved a comprehensive pilot demonstration on thermal desorption of these soils to validate the feasibility of the remedial technology which had been identified in previous studies. Thermal desorption is a technology that utilizes heating or drying of soils to induce volatilization of contaminants. These contaminants are then vaporized and either incinerated or condensed in the second stage of desorption. Mercury (Hg), which was the principal contaminate of concern, was collected by condensers in a vapor collection system. This type of system insured that the toxic mercury vapors did not escape to the atmosphere.

    2009-01-01

    Spinal immobilization is one of the most commonly performed pre-hospital procedures. Little research has been done on the movement of the neck during immobilization and extrication. In this study we used a sophisticated infrared six-camera motion-capture system (Motion Analysis Corporation, Santa Rosa, CA), to study the motion of the neck and head during extrication. A mock automobile was constructed to scale, and volunteer patients, with infrared markers on bony prominences, were extricated by experienced paramedics. We found in this pilot study that allowing an individual to exit the car under his own volition with cervical collar in place may result in the least amount of motion of the cervical spine. Further research should be conducted to verify these findings. In addition, this system could be utilized to study a variety of methods of extrication from automobile accidents. PMID:19561822

    As Brain-Computer Interface (BCI) systems advance for uses such as robotic arm control it is postulated that the control paradigms could apply to other scenarios, such as control of video games, wheelchair movement or even flight. The purpose of this pilot study was to determine whether our BCI system, which involves decoding the signals of two 96-microelectrode arrays implanted into the motor cortex of a subject, could also be used to control an aircraft in a flight simulator environment. The study involved six sessions in which various parameters were modified in order to achieve the best flight control, including plane type, view, control paradigm, gains, and limits. Successful flight was determined qualitatively by evaluating the subject's ability to perform requested maneuvers, maintain flight paths, and avoid control losses such as dives, spins and crashes. By the end of the study, it was found that the subject could successfully control an aircraft. The subject could use both the jet and propeller plane with different views, adopting an intuitive control paradigm. From the subject's perspective, this was one of the most exciting and entertaining experiments she had performed in two years of research. In conclusion, this study provides a proof-of-concept that traditional motor cortex signals combined with a decoding paradigm can be used to control systems besides a robotic arm for which the decoder was developed. Aside from possible functional benefits, it also shows the potential for a new recreational activity for individuals with disabilities who are able to master BCI control.

    The collection of data within the primary health care facilities in Iran is essentially paper-based. It is focused on family's health, monitoring of non-infectious and infectious diseases. Clearly due to the paper-based nature of the tasks, timely decision making at most can be difficult if not impossible. As part of an on-going electronic health record implementation project at Tehran University of Medical Sciences, for the first time in the region, based on a comprehensive pilot project, four urban healthcare facilities are connected to their headquarters and beyond, covering all aspects of primary health care, for the last four years. Without delving into the technical aspects of its software engineering processes, the progress of the implementation is reported, selection of summarized data is presented, and experience gained thus far are discussed. Four years passed and if time is any important reason to go by, then it is safe to accept that the software architecture and electronic health record structural model implemented are robust and yet extensible. Aims and duration of a pilot study should be clearly defined prior to start and managed till its completion. Resistance to change and particularly to information technology, apart from its technical aspects, is also based on human factors.

    This article reports a pilot study of the potential benefits of a sustained programme of singing activities on the musical behaviours and hearing acuity of young children with hearing impairment (HI). Twenty-nine children (n=12 HI and n=17 NH) aged between 5 and 7 years from an inner-city primary school in London participated, following appropriate ethical approval. The predominantly classroom-based programme was designed by colleagues from the UCL Institute of Education and UCL Ear Institute in collaboration with a multi-arts charity Creative Futures and delivered by an experienced early years music specialist weekly across two school terms. There was a particular emphasis on building a repertoire of simple songs with actions and allied vocal exploration. Musical learning was also supported by activities that drew on visual imagery for sound and that included simple notation and physical gesture. An overall impact assessment of the pilot programme embraced pre- and post-intervention measures of pitch discrimination, speech perception in noise and singing competency. Subsequent statistical data analyses suggest that the programme had a positive impact on participant children's singing range, particularly (but not only) for HI children with hearing aids, and also in their singing skills. HI children's pitch perception also improved measurably over time. Findings imply that all children, including those with HI, can benefit from regular and sustained access to age-appropriate musical activities.

    The Radiology Process Model (RPM) was previously described in terms of its conceptual basis and proposed survey items. The current study describes the first pilot application of the RPM in the field and the results of initial psychometric analysis. We used an Institutional Review Board-approved pilot RPM survey in 100 patients having outpatient interventional radiology procedures. The 24 survey items had 4 or 5 levels of severity. We assessed for missing data, items that patients found confusing, any suggestions by patients for additional items and clarity of items from patient feedback. Factor analysis was performed and internal consistency measured. Construct validity was assessed by correlation of patient responses to the items as a summated scale with a visual analog scale (VAS) they completed indicating their interventional radiology experience. The visual analog scale and the RPM summated scale were strongly correlated (r = 0.7). Factor analysis showed four factors: interactions with facility and doctors/staff, time-sensitive aspects, pain, and anxiety. The items showed high internal consistency (alpha: 0.86) as a group and approximately 0.7 to 0.9 by the factors. Analysis shows that two items could be deleted (cost and communication between radiologist and referrers). Revision of two items and potential addition of others are discussed. The RPM shows initial evidence of psychometric validity and internal consistency reliability. Minor changes are anticipated before wider use. Copyright © 2016 American College of Radiology.

    Data link Air Traffic Control (ATC) and Air Traffic Service (ATS) message and data exchange offers the potential benefits of increased flight safety and efficiency by reducing communication errors and allowing more information to be transferred between aircraft and ground facilities. Digital communication also presents an opportunity to relieve the overloading of ATC radio frequencies which hampers message exchange during peak traffic hours in many busy terminal areas. A piloted simulation study to develop pilot factor guidelines and assess potential flight crew benefits and liabilities from using data link ATC message exchange was completed. The data link ATC message exchange concept, implemented on an existing navigation computer Control Display Unit (CDU) required maintaining a voice radio telephone link with an appropriate ATC facility. Flight crew comments, scanning behavior, and measurements of time spent in ATC communication activities for data link ATC message exchange were compared to similar measures for simulated conventional voice radio operations. The results show crew preference for the quieter flight deck environment and a perception of lower communication workload.

    Study Objectives: Caffeine, a commonly consumed psychoactive substance, can have significant effects on sleep. Caffeine intake among children is increasing, mainly in the form of sodas. However, adolescent caffeine consumers may lack knowledge about the caffeine content in common beverages. If true, this very fact may hamper the assessment of the effects of caffeine consumption on sleep in children if such assessments are a priori dependent on responders being able to reliably distinguish between caffeinated and noncaffeinated beverages. This preliminary study investigated adolescents' caffeine knowledge and intake at a Cleveland-area public middle school. Methods: Seventh- and eighth-grade students were surveyed using: (1) the Caffeine Literacy and Sleep Study (CLASS), a 15-question pilot instrument designed to assess caffeine knowledge and intake by type, quantity and timing, as well as sleep habits; and (2) the Cleveland Adolescent Sleepiness Questionnaire (CASQ), a validated survey measuring excessive daytime sleepiness in adolescents. These questionnaires were distributed and collected during a specified class period. Results: Of the 635 seventh- and eighth-grade students who attended school on the day of the study, 555 (87%) participated. Lack of knowledge about caffeine content of particular drinks was noted in seventh and eighth graders of both sexes with nearly 29% unaware that their favorite drinks contain caffeine and more than 50% unable to correctly identify the drinks with the most caffeine. A low percentage of students correctly identified light-colored sodas lacking caffeine: 7-Up (24.1%), Sierra Mist (38.9%), ginger ale (39.8%), Sprite (39.8%), and Fresca (53.7%). The percentages of students correctly identifying caffeinated light-colored beverages were: Arizona Green Tea (43.5%), Mello Yellow (50.9%), and A&W cream soda (67.6%). However, Mountain Dew was correctly identified by most (93.5%) as caffeinated. Conclusions: Students were not

    The purpose of this pilot study was to determine if treatment with INSIGHT therapy, designed specifically for women, could reduce depressive and anxiety symptoms, hopelessness, and loneliness in African American women. Prevalence of mental illness differs in African Americans and Caucasians. The nonexperimental one-group pretest posttest design study examined the effectiveness of a 12-week INSIGHT group intervention. Due to the stigma of mental illness, groups met at an African American church. Reliability and validity of instruments were effectively demonstrated. Statistically significant difference was found in the level of depression but the study was underpowered to detect statistically significant differences in anxiety, hopelessness, and loneliness. Clinically significant improvement occurred for some participants in anxiety, hopelessness, and loneliness.

    To enhance patient safety from falls, many hospital information systems have been implemented to collect clinical data from the bedside and have used the information to improve fall prevention care. However, most of them use administrative data not clinical nursing data. This necessitated the development of a web-based Nursing Practice and Research Information Management System (NPRIMS) that processes clinical nursing data to measure nurses' delivery of fall prevention care and its impact on patient outcomes. This pilot study developed computer algorithms based on a falls prevention protocol and programmed the prototype NPRIMS. It successfully measured the performance of nursing care delivered and its impact on patient outcomes using clinical nursing data from the study site. Results of the study revealed that NPRIMS has the potential to pinpoint components of nursing processes that are in need of improvement for preventing patient from falls.

    The NASA Artificial Gravity Bed Rest Pilot Study was the first cross-institutional study to investigate the effectiveness of intermittent artificial gravity (AG) as a multi-system countermeasure to bed rest deconditioning in human subjects. Daily treatments by 60 min exposures to short radius centrifugation (SRC) were used to load the longitudinal body axis of eight male human subjects during 21 days of head down tilt bed rest as a means of protecting the bone, muscle, and cardiovascular systems from deconditioning. Data from these treatment subjects were compared with those from seven male human control subjects who were not exposed to SRC loading. This paper reports on implementation issues and lessons learned during the conduct of this complex study.

    2007-12-21

    Long-time NASA Dryden research pilot and former astronaut C. Gordon Fullerton capped an almost 50-year flying career, including more than 38 years with NASA, with a final flight in a NASA F/A-18 on Dec. 21, 2007. Fullerton and Dryden research pilot Jim Smolka flew a 90-minute pilot proficiency formation aerobatics flight with another Dryden F/A-18 and a Dryden T-38 before concluding with two low-level formation flyovers of Dryden before landing. Fullerton was honored with a water-cannon spray arch provided by two fire trucks from the Edwards Air Force Base fire department as he taxied the F/A-18 up to the Dryden ramp, and was then greeted by his wife Marie and several hundred Dryden staff after his final flight. Fullerton began his flying career with the U.S. Air Force in 1958 after earning bachelor's and master's degrees in mechanical engineering from the California Institute of Technology. Initially trained as a fighter pilot, he later transitioned to multi-engine bombers and became a bomber operations test pilot after attending the Air Force Aerospace Research Pilot School at Edwards Air Force Base, Calif. He then was assigned to the flight crew for the planned Air Force Manned Orbital Laboratory in 1966. Upon cancellation of that program, the Air Force assigned Fullerton to NASA's astronaut corps in 1969. He served on the support crews for the Apollo 14, 15, 16 and 17 lunar missions, and was later assigned to one of the two flight crews that piloted the space shuttle prototype Enterprise during the Approach and Landing Test program at Dryden. He then logged some 382 hours in space when he flew on two early space shuttle missions, STS-3 on Columbia in 1982 and STS-51F on Challenger in 1985. He joined the flight crew branch at NASA Dryden after leaving the astronaut corps in 1986. During his 21 years at Dryden, Fullerton was project pilot on a number of high-profile research efforts, including the Propulsion Controlled Aircraft, the high-speed landing tests of

    The North Star Research Corporation Medical Waste project is described in this report, with details of design, construction, operation, and results to date. The project began with preliminary design of the accelerator. The initial design was for a single accelerator chamber with a vacuum tube cavity driver built into the chamber itself, rather than using a commercial tube separate from the RF accelerator. The authors believed that this would provide more adjustability and permit better coupling to be obtained. They did not have sufficient success with that approach, and finally completed the project using a DC accelerator with a unique new scanning system to irradiate the waste.

    General aviation single pilot operating under instrument flight rules (GA SPIFR) was studied. The objectives of the study were to (1) develop a GA SPIFR operational profile, (2) identify problems experienced by the GA SPIFR pilot, and (3) identify research tasks which have the potential for eliminating or reducing the severity of the problems. To obtain the information necessary to accomplish these objectives, a mail questionnaire survey of instrument rated pilots was conducted. The general aviation IFR single pilot operational profile and selected data analysis examples are presented.

    To report and evaluate a complex touch massage intervention according to the British Medical Research Council framework. This study aimed to evaluate the effects of touch massage on levels of anxiety and physiological stress in patients scheduled for elective aortic surgery. The use of touch massage has increased during the past decade but no systematic studies have been implemented to investigate the effectiveness of such treatment. It is important to conduct multidisciplinary investigations into the effects of complex interventions such as touch massage. For this, the British Medical Research Council has provided a useful framework to guide the development, piloting, evaluation and reporting of complex intervention studies. A pilot study with a randomized controlled design including 20 patients (10 + 10) scheduled for elective aortic surgery. Selected outcome parameters included; self-reported anxiety, measured by the State-Trait Anxiety Inventory Form Y instrument, and physiological stress, measured by heart rate variability, blood pressure, respiratory frequency, oxygen saturation and concentrations of cortisol, insulin and glucose in serum. There were significant differences in self-reported anxiety levels before and after touch massage (p = 0.007), this was not observed in the control group (p = 0.833). There was a significant difference in self-reported anxiety levels between the touch massage group and the control group after touch massage and rest (p = 0.001). There were no significant differences in physiological stress-related outcome parameters between patients who received touch massage and controls. In our study, touch massage decreased anxiety levels in patients scheduled for elective aortic surgery, and the British Medical Research Council framework was a useful guideline for the development, evaluation and reporting of a touch massage intervention. Touch massage can reduce patients' anxiety levels and is thus an important nursing intervention in

    Preclinical and clinical studies show that the GABAB receptor agonist baclofen may represent a pharmacotherapy for alcohol dependence (AD). However, the mechanisms by which baclofen affects drinking are not well characterized; thus this pilot study investigated possible baclofen’s biobehavioral mechanisms. The design was a double-blind controlled randomized human laboratory pilot study. Fourteen non-treatment seeking alcohol-dependent heavy drinking subjects received either baclofen 10 mg t.i.d. or an active placebo (cyproheptadine 2 mg t.i.d., to control for sedation) for a 7-day period. At day 8, participants performed an alcohol cue-reactivity (CR) followed by an alcohol self-administration (ASA). Additionally, we explored possible moderators that might guide future larger studies, i.e. anxiety, family history and onset of alcoholism, and D4 dopamine receptor (DRD4) and 5-HTTLPR polymorphisms. The main results were a significant effect of baclofen for increasing stimulation (p=.001) and sedation (p<.01). Furthermore, when drinking during the ASA and the 2 days before was analyzed as a composite variable, there was a significant effect of baclofen to reduce alcohol consumption (p<.01). As for the exploratory analyses, baclofen’s effects to increase alcohol sedation and to reduce alcohol consumption were limited to those individuals with DRD4 ≥7 repeats (DRD4L). Yet, baclofen’s effects on alcohol consumption were also moderated by 5-HTTLPR LL genotype. In conclusion, baclofen’s ability to reduce alcohol drinking may be related to its effects on the biphasic effects of alcohol, but larger studies are needed to confirm these preliminary findings.

    Epidemiologic data related to agricultural pesticide poisoning cases in Burkina Faso were collected. The study was carried out using retrospective (from January 2002 to June 2010) surveys conducted among farmers and healthcare centers. One hundred and fifty-three (153) pest control products were recorded during the survey and 56 active ingredients were identified. Out of the 153 pest control products, 49 (i.e. 32%) were authorized for sale in Burkina Faso. The main risk factors are socio-demographic characteristics of farmers, their low education level, and some attitudes and practices on using agricultural pesticides. Pesticide poisonings are relatively frequent and their management was not always efficacious. Actions are needed to reduce pesticide poisoning as a global public health problem and to improve management of pesticide poisoning. To this purpose, advanced investigations should be carried out over a longer period of time to complement the present pilot study. PMID:24678256

    Canine heartworm disease is a mosquito vectored illness resulting from parasitization by the filariid worm Dirofilaria immitis. While presenting some danger to humans, the filariid has its greatest impact on the canine population. In recent years the disease has become established throughout much of the United States, perhaps as the result of diffusion from a suspected hearth in the southeastern coastal plain. While its distribution is known in general terms, much research remains to be done to assess the pattern of distribution as well as the impact of D. immitis on canine populations and their human owners for many locales. The present study provides a review of the literature on the parasite; on its distribution, particularly in the United States; and on the ecology of canine heartworm disease. A pilot study is presented which emphasizes the problems encountered in establishing a data base for observations on the disease at the local level.

    The objective of this study was to obtain measurement of cutaneous tissue perfusion central and peripheral venous pressure, and esophageal and abdominal pressure in human test subjects during parabolic flight. Hemodynamic data recorded during SLS-I and SLS-2 missions have resulted in the paradoxical finding of increased cardiac stroke volume in the presence of a decreased central venous pressure (CVP) following entry in weightlessness. The investigators have proposed that in the absence of gravity, acceleration-induced peripheral vascular compression is relieved, increasing peripheral vascular capacity and flow while reducing central and peripheral venous pressure, This pilot study seeks to measure blood pressure and flow in human test subjects during parabolic flight for different postures.

    Compounding of drugs for use in veterinary oncology is becoming increasingly common. We obtained 15 mg cyclophosphamide capsules from five different compounding pharmacies and performed potency analyses at two time points, as well as stability at 60 days. Potency results for four out of five and zero out of five (4/10) samples analysed were inadequate. Stability at 60 days was acceptable for all but one sample. This pilot study raises several important points of concern when compounding chemotherapy in dogs and cats. Further studies are necessary to solidify this data. Collaboration between pharmacists, veterinarians and regulatory bodies is needed to ensure safe and accurate delivery of compounded drugs to client-owned animals. © 2016 John Wiley & Sons Ltd.

    Around 25,000 war veterans in Portugal suffer posttraumatic stress disorder (PTSD). This clinically controlled study evaluates virtual reality exposure therapy (VRET) as an alternative procedure to reduce PTSD symptoms. Ten patients were assigned to three groups: VRET, exposure in imagination (EI), and waiting list (WL). The patients were Portuguese veterans from a series of wars fought in former African colonies more than 30 years ago. While the EI group participated in traditional imagination therapy, the VRET group was exposed to a virtual reality (VR) war scenario. Cues such as ambush, mortar blasting, and waiting for rescue were used in the VR. Patients enrolled in the VRET group showed statistical reduction of PTSD-associated disorders like depression and anxiety. Far from being conclusive, this pilot study nonetheless presents some promising data on the use of VRET on old war veteran populations.

This was followed by a 1-week pilot study in a single primary school to assess parents' support and willingness to bear or share costs, to determine children's fruit preferences, and to calculate fruit waste. Finally, the cost to local government of providing a piece of fruit to each primary schoolchild daily was calculated. A 53% response rate was obtained in the postal survey of primary school head teachers. All respondents expressed an interest in participating in future fruit promotion programmes. Of 27 primary schools, 26 that responded (96.3%) had programmes in place in which 18 had adopted specific food policies. In the pilot study at the single Anglesey primary school, a response rate of 97% from parents who expressed support for fruit promotion in school was obtained. Parents expressed their willingness to pay at least 15 pence per day towards fruit provision at break time for their children if such a service was not provided by local government. If local government was to invest in this initiative, the total cost of providing one piece of fruit per day to all primary school children in Anglesey would be 211,000 pounds per annum (2004 prices; 19 pence per child per day). This pilot study shows support by teachers and parents for initiatives to encourage primary schoolchildren to eat more fruit. Waste can be minimized by choosing fruit that children prefer, in this study, grapes, apples and oranges. The decision as to whether local government or parents are asked to pay for fruit provision is political, depending on local socioeconomic circumstances, local government priorities, national education and nutrition policies.

    Health-care professionals are increasingly asked to communicate research results to patients and consumers. Diabetes educators play a decisive role in the information process of patients with diabetes. Evidence-based medicine (EBM) is not a regular part of their training in Germany. We performed a pilot study to test whether the inclusion of a short EBM module into the standard graduate programme is feasible and leads to a meaningful increase in knowledge and skills. The study group consisted of 121 diabetes educator trainees. The EBM modules were delivered in 1- to 3-day courses. Increase in knowledge and skills were assessed using a questionnaire covering three main elements: (i) general aspects of an intervention study, (ii) effect size calculation, (iii) general aspects of evidence-based patient information and communicating numbers as patient orientated statements. Two researchers independently rated the assessment sheets. The majority of participants rated the course as important and useful but too short. Knowledge and skills in EBM increased after the course by 2 points out of 13.5 (mean score before course 5 +/- 2 vs. 7 +/- 2; P < 0.001). Inter-rater reliability analysis using Cohen's Kappa coefficients demonstrated substantial to almost perfect agreement for 10 of the 13 items. Our pilot study demonstrates that EBM education for diabetes educator trainees is feasible. However, the increase in knowledge and skills appears not to be clinically relevant. Short EBM courses are unlikely to yield important effects. More intensified course formats are necessary to meet the needs of diabetes educators.

    The purpose of this pilot study was to assess the feasibility of a Tai Chi workplace wellness program as a cost effective way of improving physical and mental health, reducing work related stress, and improving work productivity among older nurses in a hospital setting Design A randomized control trial of two groups (control and Tai Chi group). A randomized control trial of two groups (control and Tai Chi group). Northeastern academic medical center. A convenience sample of eleven female nurses (mean age 54.4 years). The Tai Chi group (n = 6) was asked to attend Tai Chi classes once a week offered at their worksite and to practice on their own for 10 minutes each day at least 4 days per week for 15 weeks. Controls (n = 5) received no intervention. SF-36 Health Survey, Nursing Stress Scale (NSS), Perceived Stress Scale (PSS), Sit-and-Reach test, Functional Reach test, the Work Limitations Questionnaire, workplace injury and unscheduled time off. The two study groups were compared descriptively and changes across time in the intervention versus control were compared. The Tai Chi group took no unscheduled time-off hours, whereas, the control group was absent 49 hours during the study period. There was also a 3% increase in work productivity and significant improvement in functional reach (p=0.03) compared to the control group. Other outcomes were not statistically significant. This pilot study demonstrates the feasibility of Tai Chi with older female workers as a cost effective wellness option in the workplace; thus encouraging replication with a larger sample. Methodological implications were also addressed. Copyright © 2012 Elsevier Inc. All rights reserved.

    Background While health literacy has gained notice on a global stage, the initial focus on seeking associations with medical conditions may have overlooked its impact across generations. Adolescent health literacy, specifically in dentistry, is an underexplored area despite the significance of this formative stage on an individual’s approach to healthy lifestyles and behaviors. Objective The aim is to conduct a pilot study to evaluate the efficacy of three major social media outlets - Twitter, Facebook, and YouTube - in supporting adolescents’ oral health literacy (OHL) education. Methods A random sample of 22 adolescents (aged 14-16 years) from an English-medium international school in Hong Kong provided informed consent. Sociodemographic information, including English language background, social media usage, and dental experience were collected via a questionnaire. A pre- and post-test of OHL (REALD-30) was administered by two trained, calibrated examiners. Following pre-test, participants were randomly assigned to one of three social media outlets: Twitter, Facebook, or YouTube. Participants received alerts posted daily for 5 consecutive days requiring online accessing of modified and original OHL education materials. One-way ANOVA ( analysis of variance) was used to compare the mean difference between the pre- and the post-test results among the three social media. Results No associations were found between the social media allocated and participants’ sociodemographics, including English language background, social media usage, and dental experience. Of the three social media, significant differences in literacy assessment scores were evident for participants who received oral health education messages via Facebook (P=.02) and YouTube (P=.005). Conclusions Based on the results of the pilot study, Facebook and YouTube may be more efficient media outlets for OHL promotion and education among adolescent school children when compared to Twitter.

    The current pilot study sought to understand optometrists' attitudes toward addressing tobacco use within the scope of their practice, and to identify opportunities within Canada to integrate optometrists as health care partners into the national tobacco cessation network. A descriptive qualitative design was used to conduct this pilot study. Five focus groups were conducted with 29 informants, including 11 practicing community optometrists and 18 senior Doctor of Optometry students from the University of Waterloo. Rationales, barriers, and opportunities to practice patterns were identified. Optometrists and optometry students knew the association of smoking with eye diseases such as age-related macular degeneration and cataract; however, some informants selectively asked patients about smoking behavior based on patient age or visit type. Most informants indicated that they did inform their patients who smoke of their increased risk of developing certain eye diseases; however, very few informants assessed whether their patients wanted to stop smoking and no informants reported that they had ever provided a patient with explicit support for tobacco cessation. This limited role in smoking cessation support for patients due, in part, to insufficient: financial incentives, training and educational tools and materials, knowledge of community resources for cessation treatments, and time during appointments. Several opportunities were identified to better integrate optometry into tobacco control efforts such as optometrists' access to patients, patients' fear of blindness as a tool to motivate behavior changes, and practitioners' openness to change. Optometrists can be a helpful addition to a smoking cessation healthcare network that already involves more than a dozen health care professions including medicine, nursing, pharmacy, dentistry, and dental hygiene. The findings of this study will be used to develop a national survey of Canadian optometrists' practice patterns

    The objective of this pilot study was to investigate the operational conditions of newly developed MBR modules for water reclamation under tropical conditions. MUDC-620A MBR modules with hollow fibre PVDF membranes from Asahi-Kasei Chemicals were used in the study. The pilot plant with capacity of 50 m(3)/d was operated continuously (24-hour) over four months on site of Ulu Pandan Water Reclamation Plant (UPWRP) in Singapore. During the study, the MLSS in membrane tank was in the range of 6,840 approximately 9,540 mg/L. Filtration operation mode of the membrane unit was 9 minutes on production and 1 minute backwash. The air scouring for the membranes was 0.18-0.30 Nm(3)/h per m(2) membrane area all of the time. Trials on different membrane fluxes were conducted to obtain the sustainable flux. The analytical results showed that COD, TOC, T-N and NH4-N of the treated water were <30 mg/L, 5-7 mg/L, <13 mg/L and <0.1 mg/L, respectively, which met the requirement of Industrial Water for reuse. TMP was in the range of 12-40 kPa and could be recovered after cleaning with 2,000 mg/L sodium hypochlorite solution. Sludge clogging could be a challenge for long-term operation with the current module design. It was concluded that it was feasible for MUDC-620A MBR to operate at a net flux of 25-29 LMH (or 0.6-0.7 m/d) for treating the municipal wastewater at UPWRP.

    Abstract Objectives: To (1) assess the feasibility and acceptability of Swedish massage among Department of Veterans Affairs (VA) health care users with knee osteoarthritis (OA) and (2) collect preliminary data on efficacy of Swedish massage in this patient group. Design: Experimental pilot study. Setting: Duke Integrative Medicine clinic and VA Medical Center, Durham, North Carolina. Patients: Twenty-five veterans with symptomatic knee OA. Interventions: Eight weekly 1-hour sessions of full-body Swedish massage. Outcome measures: Primary: Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and global pain (Visual Analog Scale [VAS]). Secondary: National Institutes of Health Patient Reported Outcomes Measurement Information System-Pain Interference Questionnaire 6b (PROMIS-PI 6b), 12-Item Short-Form Health Survey (SF-12 v1) and the EuroQol health status index (EQ-5D-5L), knee range of motion (ROM), and time to walk 50 feet. Results: Study feasibility was established by a 92% retention rate with 99% of massage visits and 100% of research visits completed. Results showed significant improvements in self-reported OA-related pain, stiffness and function (30% improvement in Global WOMAC scores; p=0.001) and knee pain over the past 7 days (36% improvement in VAS score; p<0.001). PROMIS-PI, EQ-5D-5L, and physical composite score of the SF-12 also significantly improved (p<0.01 for all), while the mental composite score of the SF-12 and knee ROM showed trends toward significant improvement. Time to walk 50 feet did not significantly improve. Conclusions: Results of this pilot study support the feasibility and acceptability of Swedish massage among VA health care users as well as preliminary data suggesting its efficacy for reducing pain due to knee OA. If results are confirmed in a larger randomized trial, massage could be an important component of regular care for these patients. PMID:25966332

    Biological factors are likely predisposing and modulating elements in sexually deviant behavior. The observation that paraphilic behavior tends to cluster in some families is intriguing and potentially raises questions as to whether shared genetic factors may play a role in the transmission of paraphilia. This pilot study introduces five families in which we found presence of paraphilia over generations. We constructed genograms on the basis of a standardized family history. Results document the aggregation of sexual deviations within the sample of families and support a clinical/phenomenological heterogeneity of sexual deviation. The concept of paraphilia in relation to phenotypic expressions and the likelihood of a spectrum of related disorders must be clarified before conclusions can be reached as to family aggregation of paraphilia based on biological factors.

    This pilot study explored psychosocial influences of e-cigarette use among dual users. Two focus groups among adult current smokers who had ever used e-cigarettes were conducted in Georgia. Discussions were audio-recorded. Principles of grounded theory and thematic analysis were employed. Reasons for initial use included curiosity and social influence. Themes related to regular use included enjoyment of sensory experiences and perception of reduced harm. Nicotine craving, social image, and convenience were reasons for initial and regular dual use. Two patterns of use emerged - (1) using e-cigarettes to supplement combustible cigarettes; and (2) to replace combustible cigarettes. Reasons for dual use were related to nicotine dependence, social influence, product appeal, and perception of reduced harm. Understanding contextual nuances of dual use can inform policy and communication.

    The author has identified the following significant results. A pilot study was conducted to determine the feasibility of mapping land use in the Great Lakes Basin area utilizing ERTS-1 data. Small streams were clearly defined by the presence of trees along their length in predominantly agricultural country. Field patterns were easily differentiated from forested areas; dairy and beef farms were differentiated from other farmlands, but no attempt was made to identify crops. Large railroad lines and major highway systems were identified. The city of Erie and several smaller towns were identified, as well as residential areas between these towns, and docks along the shoreline in Erie. Marshes, forests, and beaches within Presque Isle State Park were correctly identified, using the DCLUS program. Bay water was differentiated from lake water, with a small amount of misclassification.

    In the US, Mexican immigrant women often have better health outcomes than non-Hispanic white women despite a greater health risk profile. This cross-sectional pilot study compared women living in Chavinda, Michoacán (n = 102) to women who had migrated from Mexico to Madera, California (n = 93). The interview gathered information on acculturation and risk behaviors including smoking, alcohol use and number of sexual partners. The results suggest that more acculturated women living in the US are more likely to consume alcohol. US residence and higher acculturation level was marginally associated with having more than one sexual partner. There were no differences between odds of smoking among Chavinda and Madera women. While results with acculturation are not consistently significant due to small sample sizes, the results are suggestive that acculturation among immigrant Hispanic women in the US may be associated with adverse health behaviors, and selective migration seems less likely to account for these differences.

    This open pilot study was performed to evaluate the effect of Lamotrigine (LTG) in girls with Rett syndrome (RS) regarding seizure frequency, effect on gross motor dyspraxia and safety. Twelve girls with either the classical form of RS or the milder form fruste variants were included. The effect on epilepsy was evaluated as seizure frequency, motor performance (video comparison) and safety at clinical check up. The dosage of LTG was individualized and related to concomitant anti-epileptic drugs. Two of three girls with epilepsy responded relatively well to treatment, and for one of them even bad tantrums disappeared. LTG was useful in another four girls who became happier, more alert, more able to concentrate, and improved in contacting. Only mild adverse reactions as rash and tremor were seen. It is concluded that LTG could be worth trying as an adjunct in girls with RS, being aware of possible adverse reactions and no effect at all.

    A prospective pilot study was conducted to investigate the efficacy of radiofrequency thermal ablation (RFTA) of the soft palate to treat simple snoring. Ten consecutive, consenting patients were recruited following history, examination, Epworth scoring, sleep nasendoscopy and full polysomnography. All the patients received two treatments of three lesional RFTA of the soft palate under local anaesthesia, using the Somnus S2 generator. Each treatment was separated by 6 weeks. Patients completed a questionnaire which used visual analogue scales to score pain during the procedure as well as the postoperative period. Snoring was also scored on visual analogue scales by both the patient and the partner. Objective assessment was based on full polysomnography 3 months after the second treatment. Sixty per cent of patients subjectively reported improvement in snoring. Objectively, only 30% showed improvement in duration of snoring (38-48% better) with no change in intensity. There was high patient acceptability of the procedure.

    Pilot-scale experiments were continuously carried out for more than 9 months to study the excess biomass reduction effect using a biophase-separation bioreactor, which was designed based on food-chain theory. By separating the biophase in the wastewater treatment system, bacteria, protozoa, and metazoa could be separated from each other and dominated in different microbial communities. After degrading organic matter, bacteria were consumed by protozoa or metazoa in the following process in such a reactor. Thus, both chemical oxygen demand (COD) and biomass were reduced. During the process of treating restaurant wastewater, the excess biomass yield in this biophase-separation technique varied from 0.13 to 0.22 kg/kg COD removed, 50% lower than that from the reference system. Apart from low biomass production, this biophase-separation technique can simultaneously achieve a high COD removal efficiency and improve settleability of biosolids at a hydraulic retention time of 6 to 13 hours.

    ABSTRACT It is important that expectant parents receive accurate information about the benefits and risks of circumcision as well as the benefits and risks of having an intact foreskin when making a decision about routine infant circumcision (RIC). A pilot study was conducted using the shared decision making (SDM) conceptual model to guide expectant parents through a 3-phase decision-making program about RIC as part of their childbirth education class. The participants showed a high level of preparedness following each of the 3 phases. Preparedness score were highest for those who decided to keep their expected sons’ penises natural. This SDM program was an effective way of guiding expectant parents through the decision-making process for RIC. PMID:26834440

    Hand sensory tests do not consider distinct physiological receptors, nor detect normal range variations concerning developmental or pathological changes. We developed an instrument with a set of tests with timing and scoring for assessing haptic perception, which is the interaction between sensory and motor systems, in surfaces exploration, by moving hands. Firstly, group meetings were set for test/manual conception and materials testing. The test/manual were submitted to 30 reviewers in 3 stages (10 reviewers on each stage). The Hand Haptic Perception Instrument (HHPI) evaluates hand sensorimotor performance on six domains: depression, elevation, texture, compressibility, weight (barognosis) and form perception. Each domain requires specific materials. Score ranges from 0 to 57, being 0 the worst rating. This methodological process allowed the development of six domains and instructions to assess haptic perception. This version of HHPI is a pilot model. Further studies will determine reliability and normality ranges.

    The measurement of beliefs and attitudes on poverty and housing is important to researchers and social workers interested in examining the role that belief structures have on the development of policy and programs in these areas. This article reports pilot study findings of a new scale, The Poverty and Housing Scale (PHS), that measures this concept and evaluates its psychometric properties. Preliminary reliability was in the very good range. Examinations of content and face validity provided support of the instrument as a valid measure of beliefs and attitudes on poverty and housing. The factor analysis emerged a one factor, 13-item scale. Unlike other related scales, the PHS attempts to link the social factor of poverty and housing together. Theoretical and methodological strengths and weaknesses are considered and the implications for social work practice are discussed. The authors provide recommendations for additional testing of the instrument.

  12. Fraud Detection by Human Agents: A Pilot Study

    Almendra, Vinicius; Schwabe, Daniel

    Fraud is a constant problem for online auction sites. Besides failures in detecting fraudsters, the currently employed methods yield many false positives: bona fide sellers that end up harassed by the auction site as suspects. We advocate the use of human computation (also called crowdsourcing) to improve precision and recall of current fraud detection techniques. To examine the feasibility of our proposal, we did a pilot study with a set of human subjects, testing whether they could distinguish fraudsters from common sellers before negative feedback arrived and looking just at a snapshot of seller profiles. Here we present the methodology used and the obtained results, in terms of precision and recall of human classifiers, showing positive evidence that detecting fraudsters with human computation is viable.

    The Solihull Approach is a psychotherapeutic and behavioural model for health visitors and other professionals working with children and families to address sleeping, toileting, feeding and behavioural difficulties in young children. This pilot study used quantitative methods to assess the effectiveness of the Solihull Approach compared to standard health visitor practice. At assessment, the parent completed the short form Parenting Stress Index and a visual analogue scale rating how severe the problem was. The health visitor also completed a visual analogue scale rating their perception of the severity of the problem. This process was repeated at the end of the intervention and again at three months follow-up. Results showed statistically significant better outcome on five out of six measures for the experimental group. Results are discussed in context of a small sample size.

    This study was conducted to develop and pilot test a Korean version of the Family Attitude Scale (FAS). We developed the Korean FAS using the translation/back-translation method. Two English monolinguals assessed its translation validity by comparing the original with a back-translated English version. Translation equivalence of the FAS and the refined Korean FAS was evaluated in a convenience sample of 56 bilingual Korean college students. The internal consistency of the Korean FAS and the FAS was 0.96 and 0.76, respectively. Mean scores on the two versions did not differ (t = -0.14, p = 0.89). The test-retest correlation coefficient was 0.37 (p < .001). Although the Korean FAS needs further refinement and psychometric testing, it was translated to reflect the original version and was a reliable instrument for the Korean population.

    Research indicates that women with serious mental illness (SMI) are vulnerable to sexual abuse, resulting in adverse health outcomes such as posttraumatic stress disorder (PTSD). The purpose of this pilot study was to examine the prevalence of undiagnosed PTSD among a cohort of 20 women with SMI and reporting past sexual abuse. Furthermore, the researcher sought to identify specific symptom manifestations of PTSD among women with SMI and sexual abuse histories. Finally, the feasibility of using specific data collection tools was examined. Results indicated that PTSD was not previously diagnosed or recognized in the study sample, in spite of the presence of a sexual trauma history. The screening tools were effective in identifying depression, guilt, emotional withdrawal, blunted affect, decreased psychomotor activity, suicidal ideations, sexual dysfunction, and substance abuse. Additionally, the data collection tools provided a framework for discussing sensitive issues related to sexual abuse. Implications of this pilot study suggest the need to evaluate all women with SMI and history of sexual abuse for PTSD.

    Background The emergence of anger as an important predictor of chronic pain outcomes suggests that treatments that target anger may be particularly useful within the context of chronic pain. Eastern traditions prescribe compassion cultivation to treat persistent anger. Compassion cultivation has been shown to influence emotional processing and reduce negativity bias in the contexts of emotional and physical discomfort, thus suggesting it may be beneficial as a dual treatment for pain and anger. Our objective was to conduct a pilot study of a 9-week group compassion cultivation intervention in chronic pain to examine its effect on pain severity, anger, pain acceptance and pain-related interference. We also aimed to describe observer ratings provided by patients’ significant others and secondary effects of the intervention. Methods Pilot clinical trial with repeated measures design that included a within-subjects wait-list control period. Twelve chronic pain patients completed the intervention (F= 10). Data were collected from patients at enrollment, treatment baseline and post-treatment; participant significant others contributed data at the enrollment and post-treatment time points. Results In this predominantly female sample, patients had significantly reduced pain severity and anger and increased pain acceptance at post-treatment compared to treatment baseline. Significant other qualitative data corroborated patient reports for reductions in pain severity and anger. Conclusions Compassion meditation may be a useful adjunctive treatment for reducing pain severity and anger, and for increasing chronic pain acceptance. Patient reported reductions in anger were corroborated by their significant others. The significant other corroborations offer a novel contribution to the literature and highlight the observable emotional and behavioral changes in the patient participants that occurred following the compassion intervention. Future studies may further examine how

    Knowledge of tool-tissue interaction is mostly taught and learned in a qualitative manner because a means to quantify the technical aspects of neurosurgery is currently lacking. Neurosurgeons typically require years of hands-on experience, together with multiple initial trial and error, to master the optimal force needed during the performance of neurosurgical tasks. The aim of this pilot study was to develop a novel force-sensing bipolar forceps for neurosurgery and obtain preliminary data on specific tasks performed on cadaveric brains. A novel force-sensing bipolar forceps capable of measuring coagulation and dissection forces was designed and developed by installing strain gauges along the length of the bipolar forceps prongs. The forceps was used in 3 cadaveric brain experiments and forces applied by an experienced neurosurgeon for 10 surgical tasks across the 3 experiments were quantified. Maximal peak (effective) forces of 1.35 N and 1.16 N were observed for dissection (opening) and coagulation (closing) tasks, respectively. More than 70% of forces applied during the neurosurgical tasks were less than 0.3 N. Mean peak forces ranged between 0.10 N and 0.41 N for coagulation of scalp vessels and pia-arachnoid, respectively, and varied from 0.16 N for dissection of small cortical vessel to 0.65 N for dissection of the optic chiasm. The force-sensing bipolar forceps were able to successfully measure and record real-time tool-tissue interaction throughout the 3 experiments. This pilot study serves as a first step toward quantification of tool-tissue interaction forces in neurosurgery for training and improvement of instrument handling skills.

  3. Magnetotelluric pilot study in the Rio Grande Rift, southwest USA

    2012-12-01

    A magnetotelluric (MT) pilot study consisting of approximately 25 stations distributed in and around the Rio Grande Rift of the southwest United States was carried out in the summer of 2012. Both broadband (100 Hz to 1000 s) and long-period (up to 10 000 s) MT data were collected across two profiles that run perpendicular to the rift axis near Denver, Colorado and Taos, New Mexico, respectively. Time-domain EM data was also collected at each site to account for galvanic distortion in the near-surface. The tectonic forces and rheologic properties behind the initiation and propagation of the rift are poorly understood. Surface mapping of volcanism, normal faulting and sedimentary basins reveals a narrow band of crustal deformation confined to a region in close proximity to the rift axis while geophysical results suggest that deformation is distributed across a much broader and deeper region of the lithosphere. In particular, seismic tomography shows low seismic wave speeds into the lower crust and upper mantle. The magnetotelluric technique is a well-proven passive electromagnetic method that allows for the detection of apparent resistivity at a wide range of depth scales. Complimenting the seismic results with MT data will provide important new information on the geologic and geophysical properties that control the rifting process in this low-strain rate environment. Properties to which the MT method is particular sensitive include temperature, fluid content, and mineral alteration. Preliminary results from this most recent survey are encouraging, showing good data quality up to 10 000 s. In an important precursor to full 2D modeling, the magnetotelluric phase tensor has been used to assess the dimensionality of the electrical resistivity structure at depth. This pilot study provides proof of concept for a much larger magnetotelluric experiment planned to take place in the Rio Grande Rift in 2013.

    This article reports the results of a pilot study designed to ascertain the prevalence of lead-based paint (LBP), vermin, mold, and safety conditions and hazards and to validate observations and self-reports against environmental sampling data. Data are based on a convenience sample of 70 dwellings in a low-income, urban neighborhood in Brooklyn, New York. The vast majority of residences (96%) contained multiple conditions and/or hazards: LBP hazards (80%), vermin (79%), elevated levels of airborne mold (39%), and safety hazards (100%). Observations and occupant reports were associated with environmental sampling data. In general, the more proximate an observed condition was to an actual hazard, the more likely it was to be associated with environmental sampling results (e.g., peeling LBP was associated with windowsill dust lead levels, and cockroach sightings by tenants were associated with Blatella germanica [Bla g 1] levels). Conversely, the more distal an observed condition was to an actual hazard, the less likely it was to be associated with environmental sampling results (e.g., water damage, alone, was not statistically associated with elevated levels of dust lead, Bla g 1, or airborne mold). Based on the findings from this pilot study, there is a need for industrial hygienists and others to adopt more comprehensive and integrative approaches to residential hazard assessment and remediation. Further research--using larger, randomly drawn samples, representing a range of housing types and geographical areas--is needed to clarify the relationship between readily observable conditions, occupant reports, and environmental sampling data and to assess the cumulative impact on human health.

    The disposal of cull fruit coming from packing sheds is a large but seasonal solid waste management problem in the Central Valley. Present disposal practices include landfilling, land spreading, and use as animal feed. Typically, these methods represent an economic liability to the packers in addition to being a waste of potential resources. Cull fruit contains significant amounts of sugar which can be converted into ethanol using current technology. The ethanol has several uses, one of which is a fuel to provide on-site energy for plant processing needs. This report was intended to evaluate the potential for ethanol production from cull fruit at United Packing's Sanger plant. However, ethanol production is only one part in an overall energy management plan for the plant. Cogeneration and other power production options utilizing ethanol, to provide both total and partial energy independence from utilities are also examined. Information from the alcohol production evaluation, energy survey, biomass profile, and power production analysis is integrated in the final chapter, and an overall energy management plan is defined.

    Expert knowledge may compensate for age-related declines in basic cognitive and sensory-motor abilities in some skill domains. We investigated the influence of age and aviation expertise (indexed by Federal Aviation Administration pilot ratings) on longitudinal flight simulator performance. Over a 3-year period, 118 general aviation pilots aged 40 to 69 years were tested annually, in which their flight performance was scored in terms of 1) executing air-traffic controller communications; 2) traffic avoidance; 3) scanning cockpit instruments; 4) executing an approach to landing; and 5) a flight summary score. More expert pilots had better flight summary scores at baseline and showed less decline over time. Secondary analyses revealed that expertise effects were most evident in the accuracy of executing aviation communications, the measure on which performance declined most sharply over time. Regarding age, even though older pilots initially performed worse than younger pilots, over time older pilots showed less decline in flight summary scores than younger pilots. Secondary analyses revealed that the oldest pilots did well over time because their traffic avoidance performance improved more vs younger pilots. These longitudinal findings support previous cross-sectional studies in aviation as well as non-aviation domains, which demonstrated the advantageous effect of prior experience and specialized expertise on older adults' skilled cognitive performances.

    Adaptive interventions apply a priori decision rules for adjusting treatment services in response to participants' clinical presentation or performance in treatment. This pilot study (n = 30) experimentally examined an adaptive intervention in a misdemeanor drug court. The participants were primarily charged with possession of marijuana (73%) or possession of drug paraphernalia (23%). Results revealed that participants in the adaptive condition had higher graduation rates and required significantly less time to graduate from the program and achieve a final resolution of the case. It took an average of nearly 4 fewer months for participants in the adaptive intervention to resolve their cases compared with those participating in drug court as usual. Participants in the adaptive condition also reported equivalent satisfaction with the program and therapeutic alliances with their counselors. These data suggest that adaptive interventions may enhance the efficiency and effectiveness of drug courts and justify examining adaptive interventions in large-scale drug court studies.

  20. Evaluation of the pseudo pilot effect on baseline controller study data

    NASA Technical Reports Server (NTRS)

    Newcomb, Linda C.

    1988-01-01

    The Baseline Controller Study requires the support of pseudo pilots who input computer commands in response to air data in a simulated environment. Errors committed either by pseudo pilots, or by the computer's failure to accept commands, can result in data that is not representative of controller capabilities. Therefore, it became necessary to evaluate the actions of the pseudo pilots and determine what effect, if any, those actions had upon a given set of baseline data. The Pseudo Pilot Stations (PPS) associated with the Baseline Controller Study are user unfriendly. This fact, coupled with the human factor of the pilots themselves, required exploration of the degree the pseudo pilot's actions affected the subject air traffic controller actions during the collection of baseline data. Examination of the preliminary data collected by the Basline Controller Study subjectively determined that pseudo pilot actions do, indeed, affect the the research data. Further study is needed to quantify that affect and, perhaps, assign a value to the pseudo pilot factor rather than merely decide which simulations are valid and which are not.

    1977-01-01

    The use of a filter on the pilot's control output could improve the performance of the pilot-aircraft system. What is needed is a filter with a sharp high frequency cut-off, no resonance peak, and a minimum of lag at low frequencies. The present investigation studies the usefulness of a nonlinear, rate limited, filter in performing the needed function. The nonlinear filter is compared with a linear, first order filter, and no filter. An analytical study using pilot models and a simulation study using experienced test pilots was performed. The results showed that the nonlinear filter does promote quick, steady maneuvering. It is shown that the nonlinear filter attenuates the high frequency remnant and adds less phase lag to the low frequency signal than does the linear filter. It is also shown that the rate limit in the nonlinear filter can be set to be too restrictive, causing an unstable pilot-aircraft system response.

    The pilot study is used to guide development of a research design or to test an already developed plan; however, results of pilot work often are not reported. Pilot work can yield many valuable lessons and provide investigative training to the principal investigator and as well as evidence to funding agencies that the research is feasible and worthwhile. The pilot study described here is preliminary work on health disparities in two itinerant populations: carnival and migrant farmworker children. This pilot study had three aims: (a) identify the most productive methods to recruit subjects from these two "invisible" populations; (b) test feasibility of the research protocol; and (c) collect preliminary data on the children's health status for future research proposals.

    Helicopter emergency medical services (HEMS) are considered to have a higher risk of incidents compared to other airborne operations. As HEMS poses high cognitive demands, age-related cognitive changes of helicopter pilots might become a safety risk. The aim of this study was to estimate the association between the age of pilots and incidents in HEMS. We conducted a retrospective observational study of incidents during HEMS operations of one Austrian and two German air rescue organizations between 2007 and 2011. The sample included 257 regularly operating HEMS pilots. Age of the pilots varied between 44.52 yr (SD = 7.80) in 2007 and 46.57 yr (SD = 8.14) in 2011. Incidents were categorized as the number of HEMS operations with at least one liability damage (LD). Statistical analyses used multilevel growth curve modeling with generalized linear mixed models. 1770 LD were observed during 402.372 HEMS operations (approximately four LD per 1000 operations). From 2007 to 2011 the average number of LD per year varied between M = 0.95-1.77 for pilots < 35 yr to M = 0.25-1.53 for pilots > or = 60 yr. There was no statistically significant main effect of pilot's age on the number of LD. There was a trend of an interaction effect between age and time, which suggests that pilots with higher age tended to be involved in slightly fewer LD with time than younger pilots. In sum, findings provide no evidence that older pilots have a higher risk than younger pilots of being involved in an incident during HEMS operations.

  7. Public sharing of research datasets: a pilot study of associations

    2010-01-01

    The public sharing of primary research datasets potentially benefits the research community but is not yet common practice. In this pilot study, we analyzed whether data sharing frequency was associated with funder and publisher requirements, journal impact factor, or investigator experience and impact. Across 397 recent biomedical microarray studies, we found investigators were more likely to publicly share their raw dataset when their study was published in a high-impact journal and when the first or last authors had high levels of career experience and impact. We estimate the USA’s National Institutes of Health (NIH) data sharing policy applied to 19% of the studies in our cohort; being subject to the NIH data sharing plan requirement was not found to correlate with increased data sharing behavior in multivariate logistic regression analysis. Studies published in journals that required a database submission accession number as a condition of publication were more likely to share their data, but this trend was not statistically significant. These early results will inform our ongoing larger analysis, and hopefully contribute to the development of more effective data sharing initiatives. PMID:21339841

    The literature supports a general theme that college students lack metacognitive awareness about learning, which leads to poor examination performance and ultimately high attrition rates. However, the literature emphasizes that when college students receive instruction about learning, examination performance goes up and attrition goes down. This pilot study focused on a specific subset of learners: graduate students in a nurse anesthesia program. Given new evidence-based wellness approaches to learning, the nurse anesthesia program conducted a descriptive study aimed at exploring student perceptions. The study goals were to provide students with evidence-based information about wellness factors that influence learning. The book The New Science of Learning by Doyle and Zakrajsek (Stylus Publishing, 2013) was used to provide students with neuroscience evidence about learning that might assist their transition to graduate school. The book was mailed to 34 student registered nurse anesthetists before matriculation. An 8-item Likert-style online survey evaluated the students' perceptions of the book along with identifying any changes the students made in anticipation of starting the rigorous nurse anesthesia program. The study demonstrated that student registered nurse anesthetists could benefit from instruction about wellness approaches that enhance learning before matriculation. Additionally, the study provided the framework for future research.

    1993-03-01

    This report describes the requantification of two existing fire probabilistic risk assessments (PRAs) using a fire PRA method and data that are being developed by the Electric Power Research Institute (EPRI). The two existing studies are the Seabrook Station Probabilistic Safety Assessment that was made in 1983 and the 1989 NUREG-1150 analysis of the Peach Bottom Plant. Except for the fire methods and data, the original assumptions were used. The results from the requantification show that there were excessive conservatisms in the original studies. The principal reason for a hundredfold reduction in the Peach Bottom core- damage frequency is the determination that no electrical cabinet fire in a switchgear room would damage both offsite power feeds. Past studies often overestimated the heat release from electrical cabinet fires. EPRI`s electrical cabinet heat release rates are based on tests that were conducted for Sandia`s fire research program. The rates are supported by the experience in the EPRI Fire Events Database for U.S. nuclear plants. Test data and fire event experience also removed excessive conservatisms in the Peach Bottom control and cable spreading rooms, and the Seabrook primary component cooling pump, turbine building relay and cable spreading rooms. The EPRI fire PRA method and data will show that there are excessive conservatisms in studies that were made for many plants and can benefit them accordingly.

    Objective To explore biopsychosocial factors (beliefs, depression, catastrophizing cytokines) in individuals newly diagnosed with lung cancer and no pain in order to determine their relationship at diagnosis and across time and to determine whether these factors contribute to pain intensity or pain interference with function at pain onset. Methods A longitudinal, exploratory, pilot study was implemented in a private medical center and a VA medical center in the southeast. Twelve subjects not experiencing pain related to cancer of the lung or its treatment were recruited. A Karnofsky status of 40% and Hemoglobin of 8 grams were required. Five questionnaires were completed and 10 cc of blood was drawn at Baseline; 4 questionnaires and blood draws were repeated monthly for 5 months. One Baseline questionnaire and a pain assessment were added at Final. Demographic, clinical and questionnaire data were summarized; standardized scale scores were calculated. Results Biopsychosocial scores that were low at Baseline increased from T1-T4 but decreased slightly T5-T6. Individuals with higher pain intensity and higher pain interference at Final had higher psychosocial scores at Baseline than individuals with lower pain intensity and lower pain interference at Final. Conclusions Unrelated to disease stage, metastasis or treatment, unique, levels of biopsychosocial factors are observed in patients newly diagnosed with lung cancer who report higher levels of Pain Intensity and higher levels of Pain Interference at the time pain occurs. Replication studies are needed to validate this response pattern and determine the value of repeated individual assessments. PMID:24064756

    To compare the therapeutic effect of acupuncture and non-steroidal anti-inflammatory drug (NSAID) therapy in primary dysmenorrhea patients. Thirty-five young women with a diagnosis of primary dysmenorrhea were recruited for the study. Their dysmenorrhea severity was rated by visual analog scale (VAS) immediately prior to entry into the study. They were randomly divided into two groups; and the following month they were given NSAID (group 1, n=24) or acupuncture treatment (group 2, n=11). Pain was rated again using VAS during menstruation in both groups. After one month's treatment, pain scores were significantly lower in both groups (p<0.05). Mean pain scores decreased by 52.2% and 69.5% in the NSAID and acupuncture groups, respectively. Acupuncture was as effective as NSAID therapy for patients with primary dysmenorrhea. Since this was a pilot study with a small sample size and short follow-up period, larger studies are needed to clarify the effect of acupuncture in the treatment of primary dysmenorrhea.

    Posture, gait and balance problems are very disabling symptoms in Parkinson's disease (PD). An increased stride-to-stri de variability, reduction of automaticity and asymmetry of lower limbs function characterize parkinsonian gait. These features predispose to freezing of gait (FOG), which often leads to falls. The aim of this study was to evaluate how the modulation of asymmetry through physiotherapy might improve gait and reduce FOG, thus preventing falls. Twenty-eight PD patients entered a double-blind pilot feasibility controlled study and were evaluated at baseline and after 3 months of a rehabilitative program (performed twice a week) by means of the motor part of the Unified Parkinson's Disease Rating Scale (UPDRS-III), Gait and Falls Questionnaire, Tinetti balance and gait scale, Short Physical Performance Battery (SPPB), European Quality of Life questionnaire. Patients were randomly assigned to three treatment arms: (1) worst side improvement; (2) best side improvement; (3) standard therapy. All study arms showed a significant improvement of the Tinetti and SPPB scores. BSI led to a greater improvement than ST in terms of UPDRS-III (p = 0.01); Tinetti total score (p = 0.05) and Tinetti gait subscore (p = 0.01). Our study confirms the efficacy of physical therapy in the treatment of PD and, more importantly, suggests that specific intervention tailored on individual feature (e.g., asymmetry of motor condition) might be even more effective than standard rehabilitative programs.

    To facilitate effectiveness testing and dissemination of treatments to community based setting, therapist training manuals that are more “community friendly” are needed. The aim of the current project was to create revised versions of individual drug counseling (IDC) and group drug counseling (GDC) treatment manuals for cocaine dependence and to conduct a preliminary study of their effectiveness. After changing the format and context of existing drug counseling manuals to have greater ease of use in the community, draft manuals were given to 23 community-based counselors for their feedback. Final versions were then used in a pilot randomized clinical trial involving 41 cocaine dependent patients who received 3 months of either IDC + GDC or GDC alone treatment. Counselors implemented the new treatment manuals with acceptable levels of adherence and competence. Outcome results indicated that substantial change in drug use was evident, but the amount of abstinence obtained was limited. PMID:19038525

    The vermicomposting with Eisenia andrei of dry olive cake, a lignocellulosic waste produced during the extraction of olive oil, either alone or mixed with municipal biosolids, was studied in a nine-month pilot scale experiment. Number and biomass of earthworms and enzyme activities were periodically monitored and relevant properties of the final products were determined. In the assayed substrates, the total biomass of earthworms increased at the end of the experimental period between 9 and 12-fold respectively in comparison with the earthworm biomass initially inoculated. The increase in hydrolytic enzymes and overall microbial activity during the vermicomposting process indicated the biodegradation of the olive cake and resulted in the disappearance of the initial phytotoxicity of the substrate. However, the recalcitrant lignocellulosic nature of the dry olive cake prevented suitable humification during the vermicomposting process. For this reason, in addition to organic amendments, other management procedures should be considered.

    Caffeine, a commonly consumed psychoactive substance, can have significant effects on sleep. Caffeine intake among children is increasing, mainly in the form of sodas. However, adolescent caffeine consumers may lack knowledge about the caffeine content in common beverages. If true, this very fact may hamper the assessment of the effects of caffeine consumption on sleep in children if such assessments are a priori dependent on responders being able to reliably distinguish between caffeinated and noncaffeinated beverages. This preliminary study investigated adolescents' caffeine knowledge and intake at a Cleveland-area public middle school. Seventh- and eighth-grade students were surveyed using: (1) the Caffeine Literacy and Sleep Study (CLASS), a 15-question pilot instrument designed to assess caffeine knowledge and intake by type, quantity and timing, as well as sleep habits; and (2) the Cleveland Adolescent Sleepiness Questionnaire (CASQ), a validated survey measuring excessive daytime sleepiness in adolescents. These questionnaires were distributed and collected during a specified class period. Of the 635 seventh- and eighth-grade students who attended school on the day of the study, 555 (87%) participated. Lack of knowledge about caffeine content of particular drinks was noted in seventh and eighth graders of both sexes with nearly 29% unaware that their favorite drinks contain caffeine and more than 50% unable to correctly identify the drinks with the most caffeine. A low percentage of students correctly identified light-colored sodas lacking caffeine: 7-Up (24.1%), Sierra Mist (38.9%), ginger ale (39.8%), Sprite (39.8%), and Fresca (53.7%). The percentages of students correctly identifying caffeinated light-colored beverages were: Arizona Green Tea (43.5%), Mello Yellow (50.9%), and A&W cream soda (67.6%). However, Mountain Dew was correctly identified by most (93.5%) as caffeinated. Students were not consistently able to identify caffeine content or lack

    Research involved the characterization of gelled LNG (GELNG) with respect to process, flow, and use properties and an examination of the degree of safety enhancement attainable by gelation. The investigation included (1) an experimental examination of gel properties and gel safety characteristics as well as (2) an analytical study involving the economics and preliminary design of an industrial scale gelation system. The safety-related criterion for successful application of gelled LNG is the substantial reduction of the Maximum Distance to the Lower Flammability Limit, MDLFL. This will be achieved by first, gel-inhibition of the hydrodynamic pooling and spreading of the spill, and second, the suppressed thermal transport properties of the GELNG relative to those of LNG. The industrial scale gelation study evaluated a design capable of producing 11,000 gallons (LNG tank truck) of gel in two hours. The increased cost of gelation using this equipment was estimated at $0.23/10/sup 6/ Btu for plants with liquefaction facilities. The technical results of this study are supportive of the conclusion that gelation of LNG will reduce, relative to ungelled LNG, the hazard associated with a given size spill. Parameters of interest to the LNG facility operator (such as pumpability) are not significantly affected by gelation, and the impact on LNG delivery cost appears to be small, about 5%. Thus, the initial assumption that gelation would provide a practical means to enhance safety is supported by the results of this study. Larger scale, comparative spill tests of LNG and GELNG are now required to confirm the safety aspects of use of the gelled material.

    Energy costs and availability are major concerns in most parts of the world. Many ways of increasing energy supply and reducing consumption are being proposed and investigated. One that holds considerable promise is the extended towing of aircraft between airport runways and terminal gate areas with engines shut down. This study provides a preliminary assessment of the constraints on and feasibility of extended aircraft towing. Past aircraft towing experience and the state-of-the-art in towing equipment are reviewed. Safety and operational concerns associated with aircraft towing are identified, and the benefits and costs of implementing aircraft towing at 20 major US airports are analyzed. It was concluded that extended aircraft towing is technically feasible and that substantial reductions in aircraft fuel consumption and air pollutant emissions can be achieved through its implementation. It was also concluded that, although capital and operating costs associated with towing would be increased, net savings could generally be attained at these airports. Because of the lack of past experience and the necessity of proving the cost effectiveness of the towing concept, a demonstration of the feasibility of large-scale aircraft towing is necessary. The study evaluates the suitability of the 20 study airports as potential demonstration sites and makes recommendations for the first demonstration project.

    This report has been prepared by the Tata Energy Research Institute (TERI) for the National Renewable Energy Laboratory. It presents the results of the evaluation and impact assessment of solar photovoltaic lighting systems in the region of Sunderbans, West Bengal, that were deployed by a reputable non-governmental organization (Ramakrishna Mission) under the auspices of the INDO-US collaborative project. The objectives of the study were to evaluate the solar photovoltaic systems for their impact on the individual households as well as on the community, to assess the effectiveness of the implementation and financial mechanisms, and to draw a long-term strategy for NREL's activities in Sunderbans based on case studies of similar interventions. Under the project, provision was made to supply 300 domestic lighting systems (DLS) based on 53-Wp module capacity to individual households and a few other systems such as for lighting, medical refrigeration, and pumping water to community centers. For this study, 152 households were surveyed, of which 29 had also been a part of earlier pre- and post-installation surveys, 47 had been a part of the earlier post-installation survey, and 76 were households that were surveyed for the first time. A set of 46, out of the total 152 households, was selected for evaluating the systems for their technical performance with respect to module output, condition of the battery, and daily energy consumption. Of the total 300 modules, 2 had been stolen, 9 out of the total 300 batteries needed to be replaced, and 10 out of the 300 charge controllers were non-functional. The statistics for the surveyed households indicate 32 luminaire-related faults (blackening or flickering of compact fluorescent lights) and 11 other faults related to fuses, switches, etc.

    A 3-year long study was conducted in central Oregon to determine the possible effects of a +-500-kV d-c transmission line on cattle and crops. Two herds totaling 100 beef cows and 6 bulls were confined in pens beneath the d-c line. The cows were paired and the other members of the pairs were maintained in two herds in control pens 2000 ft west of the line. The management facilities under the power line were duplicated in the control area. There were no significant differences in consumption of feed, minerals or water between the line and control herds. Also, no effects were found on breeding, conception, calving, calf birth date, calving interval, average daily gain, adjusted weaning weight, cow weight, condition, carcass weight, and mortality. Differences were found between years for calf birth date, average daily gain, adjusted weaning weight, and cow weight. These differences were attributed to condition and age of the cows entering the study and their adjustment to pen confinement. 67 refs., 50 figs., 106 tabs.

    Extrinsic aging of the hands involves alterations in pigmentation, wrinkling, and texture as a result of chronic ultraviolet and environmental exposures. Inherent tissue properties of the skin of the dorsal hand have made it challenging to safely and effectively improve all three parameters of photoaging with a single device. Recent successes with non-ablative fractional lasers on the hands, as well as success of ablative fractional lasers on the neck and chest, raise the question of potential efficacy of ablative lasers for photorejuvenation of the hands. This was a prospective pilot study of ablative fractional CO(2) laser in 10 participants, each receiving three treatments to one hand at 4-6-week intervals. Subjective assessments by investigator and participants were performed 1 month after each treatment. At 1-month follow-up after final treatment, investigators rated mean improvement of 26-50% for wrinkles, 51-75% for pigment, and 26-50% for texture. Participants rated mean improvement after final treatment as 26-50% for wrinkles, 51-75% for pigment, and 51-75% for texture. Other than significant edema noted in one participant after the first treatment, side effects were limited to transient erythema and edema, with no long-term scarring or pigmentary alteration. In this pilot study, ablative fractional resurfacing was safe and effective for the treatment of all markers of extrinsic aging of the hands. A high degree of improvement was achieved in two to three treatments with no long-term sequelae. © 2011 Wiley Periodicals, Inc.

    healing after rupture of the Achilles tendon can be described in terms of mechanical properties of the new-formed tissue, constituting the tendon callus. In previous human studies, the elastic modulus and the density remained almost constant during 3 months after mobilization started, and then improved up to one year. So far, time-dependent deformation of the healing human tendon has not been reported. in a series of 16 patients, operated with Achilles tendon suture, we implanted tantalum beads into the tendon and measured the distance between them repeatedly during 3 min of constant loading, using an ordinary image intensifier. The patients unloaded their leg for 30 min before the test. To avoid bias, all images were investigated in a randomized and blinded order. total strain during 3 min of constant loading at 7 weeks post injury amounted to 5%, and at 19 weeks to 3%. About half of the strain, after the loading was applied, occurred during the second and third min. Considerable strain also occurred just before loading, when the patient was told that a load would be applied, but before this was actually done. the measurements were crude, and this study should be seen as a pilot. Still, visco-elastic properties seem to dominate the mechanical behavior the healing Achilles tendon from start of mobilization to 19 weeks, at least when tested after 30 min rest. This deserves further studies with more precise methods.

    Microbial water quality indicators are used to determine whether a water body is safe for recreational purposes. There have been concerns raised about the appropriate use of microbial indicators to regulate recreational uses of water bodies, in particular those located in tropical and sub-tropical environments. This prospective cohort pilot study evaluated the relationship between microbial water quality indicators and public health within two public beaches without known sewage discharge, but with historically high microbial levels for one beach, in subtropical Miami-Dade County (Florida). Monitoring was conducted in three phases: daily water monitoring, beach sand sampling, and spatially intense water sampling. An epidemiological questionnaire from a Los Angeles recreational beach-goer study was used to assess the self-reported swimming-related symptoms and exposures. There was no significant association between the number nor the type of reported symptoms and the different sampling months or beach sites, although persons who returned repeatedly to the beach were more likely to report symptoms. The number of indicator organisms correlated negatively with the frequency of symptoms reported by recreational beach goers. Results of the daily monitoring indicated that different indicators provided conflicting results concerning beach water quality. Larger epidemiologic studies with individual exposure monitoring are recommended to further evaluate these potentially important associations in subtropical recreational waters. PMID:20151031

    Atherothrombosis is a multifactorial process, governed by an interaction between the vessel wall, hemodynamic factors and systemic atherothrombotic risk factors. Recent in vitro, human ex vivo and animal studies have implicated the hormone prolactin as an atherothrombotic mediator. To address this issue, we evaluated the anatomy and function of various microvascular beds as well as plasma atherothrombosis markers in patients with elevated prolactin levels. In this pilot study, involving 10 prolactinoma patients and 10 control subjects, sidestream dark field (SDF) imaging revealed a marked perturbation of the sublingual microcirculation in prolactinoma patients compared to control subjects, as attested to by significant changes in microvascular flow index (2.74 ± 0.12 vs. 2.91 ± 0.05, respectively; P = 0.0006), in heterogeneity index (0.28 [IQR 0.18-0.31] vs. 0.09 [IQR 0.08-0.17], respectively; P = 0.002) and lower proportion of perfused vessels (90 ± 4.0% vs. 95 ± 3.0%, respectively; P = 0.016). In the retina, fluorescein angiography (FAG) confirmed these data, since prolactinoma patients more often have dilatated perifoveal capillaries. In plasma, prolactinoma patients displayed several pro-atherogenic disturbances, including a higher endogenous thrombin potential and prothrombin levels as well as decreased HDL-cholesterol levels. Prolactinoma patients are characterized by microvascular dysfunction as well as plasma markers indicating a pro-atherothrombotic state. Further studies are required to assess if prolactin is causally involved in atherothrombotic disease.

The patients unloaded their leg for 30 min before the test. To avoid bias, all images were investigated in a randomized and blinded order. Results total strain during 3 min of constant loading at 7 weeks post injury amounted to 5%, and at 19 weeks to 3%. About half of the strain, after the loading was applied, occurred during the second and third min. Considerable strain also occurred just before loading, when the patient was told that a load would be applied, but before this was actually done. Conclusion the measurements were crude, and this study should be seen as a pilot. Still, visco-elastic properties seem to dominate the mechanical behavior the healing Achilles tendon from start of mobilization to 19 weeks, at least when tested after 30 min rest. This deserves further studies with more precise methods. PMID:26605187

    Assessment of technical dexterity is currently the weakest issue in surgical evaluation. It is imperative to develop an objective exam that allows us to correct training deficiencies and abilities and to objectively feedback education programs and hospitals. The purpose of this study was to perform a correlation between theoretical knowledge and surgical skills. We performed a national pilot study in in surgeons certifying by the Mexican Board of Surgery in 2010. This was a two-stage study: written exam (stage I) and oral exam (viva voce) to all surgeons approving the written exam (stage II). In stage II we utilized an objective structured assessment of technical skills (OSATS) whose results were correlated with those of the written and oral exams. The assessment involved seven skill stations and a global rating scale to indicate correctly performed or not and a fail/pass exam, respectively. Sixty-two surgeons approved the written exam in two places. We found no statistical difference among skills in open surgery (bowel anastomosis, liver and vascular suture), laparoscopic surgery (grape pilling, cutting a circle and intracorporeal knot tying) and instrument identification. There was a statistically significant difference (p <0.001) when median values were compared between laparoscopic surgery vs. open surgery and the identification of surgical instruments. There was a correlation between theoretical knowledge and surgical skills. When applying an OSATS, we found a positive correlation between theoretical knowledge and surgical skills. This assessment proves to to be valid and reliable for the evaluation of surgical dexterity.

    The Institut für Grenzgebiete der Psychologie und Psychohygiene, Freiburg (IGPP) in cooperation with the Abteilung Naturheilkunde, University Hospital, Zürich investigated whether Distant Healing has a beneficial effect on patients with diabetes mellitus regarding the state of the disease and quality of life. The goal of the pilot study was to observe the progression of the disease with various medical and psychological measures and to explore which of them might be sensitive for measuring possible treatment effects. 14 diabetic patients were observed for a period of 16 weeks. Within this time they underwent a treatment of 4 consecutive weeks (weeks 9-12) by 5 experienced and trustworthy healers each. Patients were informed about the duration of the treatment but not about the time point of its beginning. Patients and healers never met and there was no contact between researchers and patients during the study period. With regard to medical parameters, reduction in fructosamine level was observed during the healing period, increasing fructosamine level after the end of the healing period. Sensitivity, measured only at the beginning and at the end of the study period, decreased significantly. The other parameters showed some significant changes but there was no correlation to the Distant Healing intervention. Regarding the psychological data, only improvements were observed. The results indicate the possibility that a Distant Healing intervention could have certain effects on patients with diabetes mellitus. Copyright 2002 S. Karger GmbH, Freiburg

    The US market for domestic clothes washers is currently dominated by conventional, vertical axis washers, which typically require about 40 gallons of water for each load. Although small for an individual load, the fact that 35 billion loads of laundry are washed annually in the US results in a substantial quantity of water and energy use. Although much smaller, today`s market for high-efficiency clothes washers which use much less water and energy is growing albeit slowly as manufacturers are making washers based around tumble-action, horizontal axis designs available, information about their performance and benefits is being developed, and consumers are made aware of these benefits. To help build awareness of these benefits and to accelerate markets for high-efficiency washers, DOE, under its Energy Star Program and in cooperation with Maytag Appliances, conducted a field-evaluation of high-efficiency washers using Bern, Kansas (population approximately 200) as a test bed. Baseline washer performance data as well as customer washing behavior were obtained from data collected on the existing washers of more than 100 participants in this instrumented study. Following a 2-month initial study period, all conventional washers were replaced by high-efficiency, tumble action washers, and the experiment continued for another 3-month period. Based on measured data from over 20,000 loads of laundry, the impact of the washer replacement on (1) individual customers` energy and water consumption, (2) customers` laundry habits and perceptions, and (3) the community`s water supply and waste water systems were determined and reported.

    The scientific foci of the New Particle Formation Study were the formation and evolution of atmospheric aerosols and the impacts of newly formed particles on cloud processes. Specifically, we planned to: (1) to identify the species and mechanisms responsible for the initial steps of new particle formation, i.e., the formation of thermodynamically stable clusters; (2) investigate the role of acid-base chemistry in new particle growth through measurements of ammonia and amines as well as organic and inorganic acids in both atmospheric nanoparticles and the gas phase; (3) investigate the contribution of other surface area or volume-controlled processes to nanoparticle formation and growth; (4) create a comprehensive dataset related to new particle formation and growth that can be used as input for our own thermodynamic models as well as the modeling efforts by our Department of Energy (DOE) Aerosol Life Cycle working group collaborators; (5) characterize the increase of the number and activity of cloud condensation nuclei (CCN) due to particle formation and growth; (6) determine the regional extent of new particle formation to address the role that atmospheric transport plays in determining the impacts, if any, of new particle formation on cloud number and properties.

    The study was designed to identify methods to determine adsorption applicable to Uranium Mill Tailings Remedial Action (UMTRA) Project sites, and to determine how changes in aquifer conditions affect metal adsorption, resulting retardation factors, and estimated contaminant migration rates. EPA and ASTM procedures were used to estimate sediment sorption of U, As, and Mo under varying groundwater geochemical conditions. Aquifer matrix materials from three distinct locations at the DOE UMTRA Project site in Rifle, CO, were used as the adsorbents under different pH conditions; these conditions stimulated geochemical environments under the tailings, near the tailings, and downgradient from the tailings. Grain size, total surface area, bulk and clay mineralogy, and petrography of the sediments were characterized. U and Mo yielded linear isotherms, while As had nonlinear ones. U and Mo were adsorbed strongly on sediments acidified to levels similar to tailings leachate. Changes in pH had much less effect on As adsorption. Mo was adsorbed very little at pH 7-7.3, U was weakly sorbed, and As was moderately sorbed. Velocities were estimated for metal transport at different pHs. Results show that the aquifer materials must be characterized to estimate metal transport velocities in aquifers and to develop groundwater restoration strategies for the UMTRA project.

    The results of previous studies suggest that the use of hydrogen from natural gas might be an important first step toward a hydrogen economy based on renewables. Because of infrastructure considerations (the difficulty and cost of storing, transmitting and distributing hydrogen), hydrogen produced from natural gas at the end-user`s site could be a key feature in the early development of hydrogen energy systems. In the first chapter of this report, the authors assess the technical and economic prospects for small scale technologies for producing hydrogen from natural gas (steam reformers, autothermal reformers and partial oxidation systems), addressing the following questions: (1) What are the performance, cost and emissions of small scale steam reformer technology now on the market? How does this compare to partial oxidation and autothermal systems? (2) How do the performance and cost of reformer technologies depend on scale? What critical technologies limit cost and performance of small scale hydrogen production systems? What are the prospects for potential cost reductions and performance improvements as these technologies advance? (3) How would reductions in the reformer capital cost impact the delivered cost of hydrogen transportation fuel? In the second chapter of this report the authors estimate the potential demand for hydrogen transportation fuel in Southern California.

    The Pinellas Plant was built in 1956 to manufacture neutron generators, a principal component in nuclear weapons. In September 1990, the Department of Health and Rehabilitative Services (HRS) entered into an agreement with DOE to independently examine environmental monitoring data from the plant and health data from Pinellas County to determine if an epidemiological study is technically feasible to measure possible off-site health effects from ionizing radiation. Through normal plant operations, some radioactive materials have been released to the environment. Eighty percent of the total plant releases of 107,707 curies occurred in the early years of plant operation (1957--1960). The primary materials released were tritium gas, tritium oxide and krypton-85. Environmental monitoring for radioactive releases from the plant has been done regularly since 1975. The US Public Health Service Centers for Disease Control and Prevention (CDC), in assisting HRS, has determined that sufficient radiological data exist by which a dose reconstruction can be done. A dose reconstruction can provide an estimate of how much radiological exposure someone living in the vicinity of the Pinellas Plant may have suffered from environmental releases.

    The overall purpose of this study is to explore the applicability of dielectric filled waveguide launchers to couple ion cyclotron resonant frequency (ICRF) power to magnetically confined plasma. The major advantage of dielectric filled launchers is that the geometrical dimensions of a waveguide launcher required to accommodate an electromagnetic wave of any given frequency can be reduced by the square root of the relative permittivity of the dielectric compared to air or vacuum waveguide dimensions. However, removal of the intense heat load deposited by 14 MeV neutrons in a solid dielectric filled waveguide heating system in close proximity to a fusion reactor presents several major problems: Heat is distributed throughout the volume of solid dielectric by energetic neutrons, which necessitates that a substantial fraction of the dielectric filled waveguide must be occupied by channels containing liquid coolant to remove the heat. The uniformity of the internal dielectric media of the waveguide is disrupted, and electromagnetic waves in the guide will be reflected and scattered at the discontinuities. It is highly questionable that a waveguide or waveguide launcher constructed in this manner will be an efficient means of transmitting ICRF power. This circumstance leads to employing liquid dielectrics which could satisfy both electromagnetic and coolant requirements of ICRF auxiliary launching systems simultaneously. Additionally, liquid dielectrics facilitate the motion of tuning structures through the media and preserve its dielectric uniformity in contrast to the tuning restrictions imposed by solid dielectrics in this regard.

    A pilot study for a quantitative surface analysis of multi-element alloy films has been performed by the Surface Analysis Working Group (SAWG) of the Consultative Committee for Amount of Substance (CCQM). The aim of this pilot study is to evaluate a protocol for a key comparison to demonstrate the equivalence of measures by National Metrology Institutes (NMIs) and Designated Institutes (DI) for the mole fractions of multi-element alloy films. A Cu(In,Ga)Se2 (CIGS) film with non-uniform depth distribution was chosen as a representative multi-element alloy film. The mole fractions of the reference and the test CIGS films were certified by isotope dilution—inductively coupled plasma/mass spectrometry. A total number counting (TNC) method was used as a method to determine the signal intensities of the constituent elements acquired in SIMS, XPS and AES depth profiling. TNC method is comparable with the certification process because the certified mole fractions are the average values of the films. The mole fractions of the CIGS films were measured by Secondary Ion Mass Spectrometry (SIMS), Auger Electron Spectroscopy (AES), X-ray Photoelectron Spectroscopy (XPS), X-Ray Fluorescence (XRF) Analysis and Electron Probe Micro Analysis (EPMA) with Energy Dispersive X-ray Spectrometry (EDX). Fifteen laboratories from eight NMIs, one DI, and six non-NMIs participated in this pilot study. The average mole fractions of the reported data showed relative standard deviations from 5.5 % to 6.8 % and average relative expanded uncertainties in the range from 4.52 % to 4.86 % for the four test CIGS specimens. These values are smaller than those in the key comparison CCQM-K67 for the measurement of mole fractions of Fe-Ni alloy films. As one result it can be stated that SIMS, XPS and AES protocols relying on the quantification of CIGS films using the TNC method are mature to be used in a CCQM key comparison. Main text.

    An HVdc multiconverter configuration results when more than one converter station is located within the same electrical region. Such a situation will be a natural consequence of the growing use of the HVdc technology. Relevant questions relating to multiconverter configurations have been analyzed in the scope of this research project. In particular, special emphasis has been devoted to the HVdc inverter multiinfeed schemes, since such a situation will be more commonly found in future applications and usually results in the most severe ac/dc interactions. The main purpose of this project is to present a general insight into the potential problems resulting from multiinfeed HVdc operation, using networks based on realistic power system configurations. Power system studies have been performed using several digital (Load-Flow, Transient Stability, Eigenvalue and EMTP programs) and analog (DC Simulator) tools in a complementary basis to investigate both low and high frequency interaction phenomena. The project was conducted to evaluate the technical aspects of the various ac/dc and dc/dc interactions. It addressed small signal stability, an overview of the entire system transient and dynamic stability, some aspects of the ac voltage stability problem and HVdc control stability including the effects of the VDCOL units and possible occurrence of commutation failures at inverter stations after recovery from faults. This report identifies the potential problems resulting from multiinfeed situations and proposes practical solutions. It also presents a survey on how the various HVdc system controllers can be coordinated to provide the interconnected ac system with an improved dynamic performance, a high level of operational flexibility and the maximization of the overall system loadability.

    This pilot study compared the efficacy of a forgiveness intervention with a fibromyalgia (FM) health intervention on women with FM who have experienced emotional, physical, or sexual abuse, and emotional or physical neglect, in childhood by one of their parents. Eleven women with FM between the ages of 21 and 68 were randomized to the forgiveness intervention (n = 5) or the FM health intervention (n = 6), and completed the once-weekly individualized program for 24 weeks. The participants completed measures assessing forgiveness, overall FM health, depression, anger, anxiety, self-esteem, and coping strategies at the pretest, the posttest, and the 12-week follow-up test. They also completed the forgiveness intervention and FM health intervention final tests at the posttest, which assessed their knowledge on forgiveness and FM health. The forgiveness intervention participants had greater improvements in forgiveness (p < .001) and overall FM health (p = .046) from the pretest to the posttest, and in forgiveness (p = .018) and state anger (p = .027) from the pretest to the follow-up test than the FM health intervention participants. Moreover, the forgiveness intervention participants scored higher on the forgiveness final test than the FM health intervention participants (p < .001), and the FM health intervention participants scored higher on the FM health final test than the forgiveness intervention participants (p < .001). The results indicate that the forgiveness intervention was potentially helpful in improving forgiveness and overall FM health, and in decreasing state anger of this particular sample of women with FM.

    In military aviation, high performance aircraft pilots are exposed to +Gz acceleration at longer durations and higher magnitude than transport/helicopter pilots. The purpose of this study was to reveal the negative or positive cardiac responses to this occupational high +Gz exposure. Our study design was cross-sectional and observational. We have evaluated 21 echocardiographic parameters of 63 pilots who applied for aircrew periodic medical examination. Of 63 pilots, 33 were grouped as high performance aircraft pilots group (Group A) and 30 were grouped as control group (Group B) whose aircraft type was transport or helicopter. Means of demographic and echocardiography parameters between two groups were compared statistically with Student's t-test, Mann- Whitney U or Chi-square test as appropriate. Among all echocardiographic parameters, mean TV A (tricuspid valve peak velocity during late diastolic filling) was significantly higher and TV E (peak velocity during early diastolic filling)/ A ratio was significantly lower for Group A pilots (p<0.05). In Group A pilots, mean TV A and TV E/A ratio were (52.12 ± 13.85) and (1.36 ± 0.30) respectively. In Group B pilots, mean TV A and TV E/A ratio were (42.61 ± 6.42) and (1.53 ± 0.20) respectively (p=0.001 for TVA and p=0.005 for TV E/A). Mean pulmonary artery pressure (PAP) of Group A pilots (32.04 ± 9.09) was higher than Group B pilots (28.76 ± 7.9) but it was not statistically significant (p>0.05). We conclude that according to the results of our study, long term +Gz exposure has no effects on cardiac morphologic and systolic functions but has effects on right ventricular diastolic functions. We have considered that these effects may be a result of chronic +Gz adaptation or high PAP levels.

    Leadership has been identified as a key variable for the functioning of teams and as one of the main reasons for success or failure of team-based work systems. Pediatricians often function as team leaders in the resuscitation of a critically ill child. However, pediatric residents often report having little opportunity to perform in the role of team leader during residency. In order to gain more insight into leadership skills and behaviors, we classified leadership styles of pediatric residents during simulated emergencies. We conducted a prospective quantitative study to investigate leadership styles used by pediatric residents during simulated emergencies with clinical deterioration of a child at a pediatric ward. Using videotaped scenarios of 48 simulated critical events among 12 residents, we were able to classify verbal and nonverbal communication into different leadership styles according to the situational leadership theory. The coaching style (mean 54.5%, SD 7.8) is the most frequently applied by residents, followed by the directing style (mean 35.6%, SD 4.1). This pattern conforms to the task- and role-related requirements in our scenarios and it also conforms to the concept of situational leadership. We did not find any significant differences in leadership style according to the postgraduate year or scenario content. The model used in this pilot study helps us to gain a better understanding of the development of effective leadership behavior and supports the applicability of situational leadership theory in training leadership skills during residency.

    Effective interventions are needed for women long overdue for screening mammography. The purpose of this study is to pilot test an intervention for motivating overdue women to receive a mammogram. Subjects aged 45-79 without a mammogram in > or =27 months and enrolled in study practices were identified from claims data. The intervention included a mailed, educational booklet, computer-assisted barrier-specific tailored counseling and motivational interviewing, and facilitated, short-interval mammography scheduling. Of 127 eligible women, 45 (35.4%) agreed to counseling and data collection. Most were > or =3 years overdue. Twenty-six (57.8%) of the counseled women got a mammogram within 12 months. Thirty-one (72.1%) of 43 counseled women moved > or =1 stage closer to screening, based on a modified Precaution Adoption Process Model. It is feasible to reach and counsel women who are long overdue for a mammogram and to advance their stage of adoption. The intervention should be formally evaluated in a prospective trial comparing it to control or to proven interventions.

    Mirror therapy, which provides the visual illusion of a functional paretic limb by using the mirror reflection of the non-paretic arm, is used in the rehabilitation of hemiparesis after stroke in adults. We tested the effectiveness and feasibility of mirror therapy in children with hemiplegia by performing a pilot crossover study in ten participants (aged 6-14 y; five males, five females; Manual Ability Classification System levels: one at level I, two at level II, four at level III, three at level IV) randomly assigned to 15 minutes of daily bimanual training with and without a mirror for 3 weeks. Assessments of maximal grasp and pinch strengths, and upper limb function measured by the Shriner's Hospital Upper Extremity Evaluation were performed at weeks 0 (baseline), 3, 6 (intervention), and 9 (wash-out). Testing of grasp strength behind the mirror improved performance by 15% (p=0.004). Training with the mirror significantly improved grasp strength (with mirror +20.4%, p=0.033; without +5.9%, p>0.1) and upper limb dynamic position (with mirror +4.6%, p=0.044; without +1.2%, p>0.1), while training without a mirror significantly improved pinch strength (with mirror +6.9%, p>0.1; without +21.9%, p=0.026). This preliminary study demonstrates the feasibility of mirror therapy in children with hemiplegia and that it may improve strength and dynamic function of the paretic arm.

    Regardless of the type of prosthetic lower limb, successful ambulation requires proper prosthetic attachment. To help alleviate many of the problems associated with prosthetic attachment, direct skeletal attachment (DSA) has been proposed as an alternative to conventional sockets. The purpose of the current study was to evaluate the feasibility of lower limb DSA in a micropig model and to develop a systematic approach to the development and analysis of DSA systems. The DSA device consisted of two stages. The load-carrying stage embedded in the bone canal was designed using bone remodeling theory in conjunction with finite element analysis to approximate implant-induced remodeling and stabilization out to 36 months postimplantation. The skin-interfacing stage was designed to maintain an immutable infection barrier where the prosthesis exited the body. Following successful design, fabrication, and benchtop evaluation, the device was surgically implanted in a Yucatan micropig. The animal trial was successful out to 10 weeks and revealed potential flaws in the surgical protocol related to thermal necrosis. However, no signs of infection were present at the time of implant retrieval. While results of this pilot study support the feasibility of a DSA approach to prosthetic limb attachment, additional animal trials are necessary to prove long-term viability.

    Continuous personal monitoring is the benchmark for air pollution exposure assessment. Black carbon (BC) is a strong marker of primary combustion like vehicle and biomass emissions. There have been few studies that quantified daily personal BC exposure and the contribution that different microenvironments make to it. In this pilot study, we used a portable aethalometer to measure BC concentrations in an individual's breathing zone at 30-s intervals while he performed his usual daily activities. We used a GPS and time-activity diary to track where he spent his time. We performed twenty 24-h measurements, and observed an arithmetic mean daily exposure concentration of 603 ng/m3. We estimated that changing commute modes from bus to train reduced the 24-h mean BC exposure concentration by 29%. Switching from open windows to closed windows and recirculated air in a car led to a reduction of 32%. Living in a home without a wood-fired heater caused a reduction of 50% compared with a wood-heated home. Our preliminary findings highlight the potential utility of simple approaches to reduce a person's daily BC exposure.

    The authors sought to describe the use of the testimony method of psychotherapy in a group of traumatized adult refugees from genocide in Bosnia-Herzegovina. The subjects were 20 Bosnian refugees in Chicago who gave written informed consent to participate in a case series study of testimony psychotherapy. All subjects received testimony psychotherapy, averaging six sessions, approximately 90 minutes, weekly or biweekly. Subjects received standardized instruments for posttraumatic stress disorder (PTSD), depression, traumatic events, global functioning, and prior psychiatric history. The instruments were administered before treatment, at the conclusion of the treatment, and at the 2- and 6-month follow-ups. The posttreatment assessments demonstrated significant decreases in the rate of PTSD diagnosis, PTSD symptom severity, and the severity of reexperiencing, avoidance, and hyperarousal symptom clusters. Depressive symptoms demonstrated a significant decrease, and there was a significant increase in scores on the Global Assessment of Functioning Scale. Two-month and 6-month follow-up assessments demonstrated further significant decreases in all symptoms and an increase in scores on the Global Assessment of Functioning Scale. This pilot study provides preliminary evidence that testimony psychotherapy may lead to improvements in PTSD and depressive symptoms, as well as to improvement of functioning, in survivors of state-sponsored violence.

    Caffeine is considered to be a dehydrating agent with detrimental effects on the quality of voice of persons ingesting it. This has led medical personnel dealing with voice disorders, especially in the case of professional voice users, to give advice against the use of caffeine. Yet this is an anecdotal truth as an extensive Medline literature search did not reveal any scientific evidence of caffeine being proven to have adverse effects on the vocal folds. We, therefore, initiated this pilot study to ascertain the connection between caffeine and voice quality on a laboratory basis. Two hundred and fifty mg of caffeine were provided to eight volunteers in tablet form, and blood levels along with laryngograph readings were recorded to document the changes produced. Analysing the irregularities of frequencies in a) free speech b) a reading passage and c) singing 'Happy Birthday', substantial changes were seen to authenticate the fact that caffeine does produce alterations in voice quality but these alterations have considerable intra-subject variability. A full study with wider parameters is to be performed on this subject as we consider it to be of importance in the management of voice disorders.

    The aim of this study is to develop a treatment diary for patients receiving spasticity treatment including botulinum toxin injection and physiotherapy and/or occupational therapy. The diary focuses on problems triggered by skeletal muscle overactivity; agreed goals for treatment and the patient’s self-evaluation of achievement on the Goal Attainment Scale; which skeletal muscles were injected; physiotherapists’ and occupational therapists’ evaluation of the patients’ achievement of objectives on the Goal Attainment Scale; and proposals for optimization of treatment and changing goals. The evaluation included a satisfaction questionnaire and the WHO-QoL BREF and WHO-5 well-being score. Overall, 10 patients were enrolled in the pilot study. The patients were generally satisfied with the diary, found that it involved them more in their treatment and made it easier to set personal goals, and found it worth the time spent using it. However, no clear advantage in relation to their quality of life (WHO-QoL BREF and WHO-5 well-being score) was reported. PMID:28225535

    Two distinct patterns of sweet taste liking have been described: one showing a peak liking response in the mid-range of sucrose concentrations and the other showing a monotonic liking response at progressively higher sucrose concentrations. Classification of these patterns has been somewhat arbitrary. In this report, we analyzed patterns of sweet taste liking in a pilot study with 26 adults including 14 women and 12 men, 32.6 ± 14.5 years of age with body mass index 26.4 ± 5.1 kg/m² (mean ± SD). Sweet taste liking was measured for 10 levels of sucrose solutions (0.035 M to 1.346 M). Participants rated their liking of each solution using a visual analog scale with 0 indicating strongly disliking and 100 strongly liking. The cluster analysis demonstrated two distinct groups: 13 liked relatively low sucrose concentrations and liked high sucrose concentrations less, and 13 liked high sucrose concentrations greatly. If we use the 0.598 M sucrose solution alone and a cutoff liking score of 50, we can distinguish the two clusters with high sensitivity (100%) and specificity (100%). If validated in additional studies, this simple tool may help us to better understand eating behaviors and the impact of sweet taste liking on nutrition-related disorders.

    Commercially available exergames that are for wheelchair-bound individuals with spinal cord injury (SCI) are scarce. This study sought to identify exergames for individuals with SCI that are "dose-potent" for health benefits. Six participants with SCI were recruited for a pilot study to investigate the exercise intensity of selected exergames (Move Tennis, Move Boxing, and Move Gladiator Duel) for the potential to improve health. Issues relating to exergaming for individuals with SCI were identified, and a Move Kayaking exergame was conceived using relevant design processes in an iterative manner. These processes included the following: participant needs and requirements, system requirements (hardware), system architecture (physical and operational views), and integration and verification of the finished system. Emphasis was given to operational and physical designs of the Move Kayaking exergame. Move Boxing, Move Gladiator Duel, and Move Kayaking achieved moderate intensity exercise, while Move Tennis only achieved exercise of low intensity based on participants' metabolic equivalent. However, all four exergames achieved at least moderate intensity based on individuals' ratings of perceived exertion (RPE). The intensity classification while playing Move Boxing, Move Tennis, Move Gladiator Duel, and Move Kayaking, using RPE, reported adequate exercise intensities prescribed by exercise guidelines.

    Background Venous ulcers represent 70% of the lower limb ulcers. They are difficult to heal, requiring a correct diagnostic and therapeutic approach. Many products have been developed to healing, such as homologous platelet gel obtained from the platelet concentrate exceeding from blood transfusion. Objective To evaluate the safety and efficacy of homologous platelet gel in venous ulcers compared with hydrocolloid dressing. Method A pilot randomized clinical trial in patients with venous ulcers. Randomized groups (homologous platelet gel and hydrocolloid groups) were followed for 90 days and were assessed through the evolution of ulcerated area, qualitative analysis of vascularization and adverse events. Both groups used elastic compression. Results We included 16 participants, with a total of 21 venous ulcers. Both treatments promoted a reduction of the areas of the ulcers in 90 days (mean 69%), there was significant difference between the groups concerning the gradual reduction of the ulcers areas, favorably to the hydrocolloid (70% vs 64%; p <0.01). There were some mild adverse events in both groups. Study limitations Single-center study with a small number of patients, preventing more accurate assessment of the effects of platelet gel. Conclusion The homologous platelet gel associated with the elastic compression can be an alternative to the venous ulcer treatment and is safe due to the occurrence of a few mild local adverse events and no serious adverse events. Clinical trials with larger numbers of patients must be performed to maintain the indication of this treatment for venous ulcer. PMID:28954098

    We aimed to test a new telerehabilitation device for stress urinary incontinence (SUI) in order to make an initial assessment of its effectiveness. Randomized, controlled pilot study. experimental group (10 patients): pelvic floor muscle training, device training and home treatment with it; control group (9 patients): conventional rehabilitation treatment. Outcome measures (baseline and 3 months) overall and specific quality of life: International Consultation Incontinence Questionnaire and King's Health Questionnaire, bladder diary, perineometry, satisfaction with the program and degree of compliance. Baseline characteristics were similar in both groups. There was no statistically significant difference for any outcome measures between groups at the end of the follow-up. The change in perineometry values at baseline and after the intervention was significant in the experimental group (23.06 to 32.00, P=.011). No group in this study had any serious adverse effects. The tested device is safe and well accepted. Although there is some evidence of its efficacy in the rehabilitation treatment of SUI, larger trials are needed to appropriately evaluate the potential advantages.

    Medical treatments take place in social contexts; however, little research has investigated how social modelling might influence treatment outcomes. This experimental pilot study investigated social modelling of treatment effectiveness and placebo treatment outcomes. Fifty-nine participants took part in the study, ostensibly examining the use of beta-blockers (actually placebos) for examination anxiety. Participants were randomly assigned to observe a female confederate report positive treatment effects (reduced heart rate, relaxed, calm) or feeling no different. Heart rate, anxiety and blood pressure were assessed, as were symptoms and attributed side effects. Heart rate decreased significantly more in the social modelling compared to control condition, p = .027 (d = .63), and there were trends towards effects in the same direction for both anxiety, p = .097 (d = .46), and systolic blood pressure, p = .077 (d = .51). Significant pre-post placebo differences in heart rate, anxiety and diastolic blood pressure were found in the social modelling group, ps < .007 (ds = .77-1.37), but not the control condition, ps > .28 (ds = .09-.59). Social observation of medication effectiveness enhanced placebo effectiveness in heart rate, and showed a trend towards enhancing treatment effectiveness in both anxiety and systolic blood pressure. Social modelling may have utility in enhancing the effectiveness of many active medical treatments.

    To date very little research has been conducted on night-to-night variability in the incidence of insomnia. It is unclear from prior research whether subjects with primary insomnia (PI) exhibit good sleep (or better than average sleep) on some interval basis. In the present study, pilot data are provided on: (1) the frequency with which 'good sleep' occurs in subjects with PI; and (2) whether these events occur in a non-random manner. Ten subjects with PI participated in this 'naturalistic' study. All subjects completed daily sleep diaries for a minimum of 20 days. None of the subjects received treatment for their insomnia during the monitoring period. The night-to-night data were evaluated by typing each night's sleep as 'Good' or 'Bad', and then by determining the number of bad nights that occurred prior to a good night for each subject. Good and bad nights were typed in two ways: (1) using a > or =85% cut-off and (2) using a better than the individual's mean sleep efficiency (idiographic cut-off). Subjects exhibited good sleep on between 29% (>85% criteria) and 55% (idiographic criteria) of the nights evaluated. The temporal patterning analysis (based on an idiographic cut-off) revealed that better than average sleep most frequently occurred (>89% of instances) following one to three nights of poor sleep. These data suggest that insomnia severity may be mediated/moderated by sleep homeostasis and that the homeostat, or input to the homeostat, may be abnormal in patients with PI.

    Internet-facilitated sexual offending is receiving increased forensic and clinical attention. Two issues confront this field. First, studies are equivocal as to whether (or not) the possession of Internet pornography can escalate to contact sexual offenses against a child, and second, federal judges have been questioning the length of sentences for users only of child pornography. The findings of this pilot study of 101 federal Internet offenders revealed over half of the men at the time of arrest were employed, educated, were in (or had been in) a relationship, had children, and did not have a prior criminal offense, suggesting a changing profile of a convicted sex offender. Forensic and psychiatric nurses who evaluate users of child pornography contraband need to be knowledgeable of Internet file transfer technology and the various types of contraband viewed specifically for the age of the preferred child, extreme acts to the child (e.g., bondage, S&M), and whether the user prefers images of adults with children or images of children only.

    Global Initiative on Chronic Obstructive Lung Disease (GOLD) guidelines recently removed stage 0, a group with symptoms but without airways obstruction, from their severity staging. However, in practice this group may still be diagnosed and medically managed. The aim of this study was to characterize healthcare utilization patterns of chronic obstructive pulmonary disease (COPD) patients by disease severity, focusing on the possible unique attributes of patients who would have been classified as GOLD stage 0. This is a prospective cohort pilot study performed at the Hines Veterans Administration Hospital. One hundred twenty patients with a diagnosis of COPD were enrolled. The participants completed quality-of-life questionnaires and a pulmonary function test. Healthcare utilization data were obtained 1 year prior and 2 years after the enrollment date. Three disease severity groups were defined based on GOLD criteria for comparison [GOLD stage 1-2 (GS 1-2), GOLD stage 3-4 (GS 3-4), and formerly GOLD stage 0 ("at risk")]. The "at risk" group had an average of 14.4 (SD = 30.5) outpatient visits/year and 0.3 (SD = 0.8) hospitalizations/year, which were higher than the other groups, but this was not statistically significant. Respiratory medications were used by 6 (26%), 30 (59%), and 40 (91%) patients from "at risk" to GS 3-4, respectively. Patients in the "at risk" group had a decrement in health status, significant utilization of healthcare services, and were often receiving medications not consistent with guidelines.

    The purpose of this study was to determine the effectiveness of an in-room calendar to correct temporal disorientation in a brain-injured population. Thirty consecutive brain injured patients (16 traumatic, 14 non-traumatic) admitted to a brain injury rehabilitation unit were randomly assigned to either a group with in-room calendars (n = 14) or a group without calendars (n = 16). A baseline Temporal Orientation Test (TOT) score was obtained. Daily TOT scores were obtained for patients throughout their rehabilitation stay or until two consecutive normal scores were obtained. When orientation errors were made, they were corrected and the attention of the patient was drawn to the calendar. There were no statistically significant associations between group and age, gender or mean GCS (for patients with traumatic etiology). Only baseline length of post-traumatic amnesia (PTA) had a significant association with eventual emergence from PTA (as defined by a normal score on the TOT). Age and presence of calendar were not significant. In-room calendars have been espoused as orientation aides. The data from this pilot study suggest that calendars do not hasten re-orientation. This finding suggests that other widely held but not rigorously tested beliefs regarding cognitive rehabilitation may need to be examined.

    This pilot study aimed to gain empirical data on the social and economic impacts of child burns on children and parents, in the context of the outpatient setting. A questionnaire was completed by 52 parents of paediatric patients attending the burns outpatient department at Queen Victoria Hospital (QVH), East Grinstead, for at least the third time. Children's medical notes were used to extract demographic and medical data. Quantitative data was analyzed statistically and qualitative data was analyzed manually using content analysis. The financial burden related to the injury posed the greatest impact on parents, and was mainly associated with making the journey to the hospital, with lower income households being most affected. Self-employed parents and those who had to attend more than 6 hospital appointments also ran into difficulties. On the whole, there was not a considerable social impact on the burn-injured child, which may reflect the minor nature of burns in this study (mean depth partial thickness, median TBSA 1.0%). Parents were shown to perceive a greater impact from their child's burn injury than their child. Certain groups of parents were identified as requiring additional support following the burn injury.

    This paper is a report of a pilot study conducted to investigate the effect of a tailor-made ergonomic intervention programme for community nurses. The nursing profession is known to be a high risk group for work-related musculoskeletal disorders. Community nurses are at risk as they have to travel to patients' homes and work in varied environments daily. Their occupational risk factors are unique and intervention strategies need to be specially designed to address these issues. The study was conducted from August 2007 to September 2008 in Hong Kong with community nurses from three hospitals. The intervention group (n = 14) received a multi-faceted ergonomic intervention programme over an 8-week period, with group training, onsite individual training, equipment modification, exercise programme, typing and computer workstation advice. The control group (n = 12) received no interventions. Both groups had baseline and follow-up assessments, which included musculoskeletal symptoms, perceived risk factors and functional outcome and physical mobility measures. The intervention group showed statistically significantly improved symptom scores and neck and upper limb functional outcomes at postintervention. The control group showed no change in symptom or functional outcomes. A multifaceted intervention programme may be more effective than interventions that mainly focus on ergonomic training and could be considered by community or home care nursing groups in other countries. The programme was based on risk assessment and may be a useful reference for other nursing groups in other countries.

    Thyroid cancer is one of the most prevalent cancers. About 3-8% of the people in the United States have thyroid nodules, and 5-15% of these nodules are malignant. Fine-needle aspiration biopsy (FNAB) is a standard procedure to diagnose malignity of nodules. However, about 10-20% of FNABs produce indeterminable results, which leads to repeat biopsies and unnecessary surgical operations. We have explored photoacoustic (PA) imaging as a new method to identify cancerous nodules. In a pilot study to test its feasibility, we recruited patients with thyroid nodules (currently 36 cases with 21 malignant and 15 benign nodules), acquired in vivo PA and ultrasound (US) images of the nodules in real time using a recently-developed clinical PA/US imaging system, and analyzed the acquired data offline. The preliminary results show that malignant and benign nodules could be differentiated by utilizing their PA amplitudes at different excitation wavelengths. This is the first in vivo PA analysis of thyroid nodules. Although a larger-scale study is needed for statistical significance, the preliminary results show the good potential of PA imaging as a non-invasive tool for triaging thyroid cancer.

    To observe and describe the positions and movements women choose while immersed in water during the first stage of labor. Descriptive, observational pilot study. A rural community hospital that provided hydrotherapy in labor. Women (N = 7) who intended to use hydrotherapy in labor were recruited prenatally from a midwife-managed practice. For 15 minutes of each hour during the first stage of labor, position and movements of the participants were observed and recorded on a laptop computer. The observational tool was developed for this study from a review of the literature and interviews with nursing experts; 435 observations were recorded. Women were free to choose when and how long to use hydrotherapy and had no restriction on their positions and movements. Only 3 of the 7 participants labored in the tub. Women demonstrated a greater range of positions and movements in the tub than in bed, both throughout labor and during late first-stage labor (7-10 cm of dilatation). Women had more contractions and made more rhythmic movements while in the tub than in bed. Hydrotherapy may encourage upright positions and movements that facilitate labor progress and coping, helping women avoid unnecessary interventions.

    The objective of this pilot study is to assess the need, desire, and applicability of a mammography promotion project in the emergency department (ED). A convenience sample from the ED of a public University hospital was surveyed to determine their mammography status, interest in a program to promote mammography, and barriers to mammography. The survey included demographics information, health care access, including health insurance and primary care provider, mammography status and date of mammogram, as well as a checklist of potential barriers. Participants were also asked whether they would be interested in mammography promotion in this setting. More than 15% of the 197 women surveyed had never received a mammogram, and more than half had not received 1 in the past year. The most common barriers to mammography were competing demands and money. Three quarters of the women said they would be interested in mammography promotion while waiting for care in the ED. This study provides promise that mammography promotion activities may be appropriately placed in the ED and provides a solid platform from which researchers and nurses may launch efforts to develop preventive health interventions in innovative public health care settings. © 2010 Wiley Periodicals, Inc.
