Optimization of Spark and ESD Propellant Sensitivity Tests. A review

Field: Chemical Engineering (Physical Sciences)

Abstract All cured propellants can pass small‐scale spark sensitivity tests, yet some, generally involving larger propellant samples, are electrostatic discharge (ESD) sensitive. These tests fail to rank propellants because the test methods themselves are not optimized and frequently use instrumentation which does not indicate the energy transferred to the sample. For spark ignition of premixed combustible gases or fuel sprays in air, minimum energies are measured and considered thermochemical properties for a given fuel/air ratio, initial temperature and pressure, and for a spray, a given droplet size distribution. Obtaining such data requires monitoring the total energy discharged across the gap during the spark and parametric studies where gap length and spark duration are varied systematically to establish the true minimum (essential to hazard/risk analysis). Electrode geometry and tip design, as well as electrode material, are other important considerations. Present spark and ESD sensitivity tests used for solid propellants are reviewed in the context of methods more likely to provide meaningful initiation thresholds.
Consider BMI Change When Evaluating Nutrition Intervention Impact on Eating Competence: Findings from an Intervention with Eating Competence Constructs for Adults

Field: Health Professions (Health Sciences)

OBJECTIVES: Examine change in adult eating competence (EC) over a 12 month period following participation in a controlled 7-month nutrition education intervention with EC constructs. METHODS: Parents of 4(th) grade youth in a cluster randomized impact assessment of a 7 month school-based culinary and physical activity intervention were assigned to 1 of 4 incrementally complex treatments that included components congruent with EC tenets. An online survey included validated measures of EC (ecSI 2.0(TM)), physical activity, stress, diet quality, healthful modeling, self-efficacy (SE) to offer fruits and vegetables to youth, and self-reported height/weight. EC was defined as ecSI 2.0(TM )≥32. Measures were completed at baseline (BL), post-intervention (FU) and 5 months later (FU2). SPSS 24.0 analyses included repeated measures general linear modeling, means testing, chi square, Pearson correlation. RESULTS: Mean age of the mostly female (86%) sample (n = 418) was 39.1 ± 6.0 y; at FU2 126 were intervention and 96 control parents. BL analyses supported EC tenets with greater ecSI 2.0(TM) scores associated with less stress, lower BMI, less overweight/obesity, greater physical activity, greater SE and modeling behaviors (all P < 0.01). These relationships persisted at FU (n = 220) and FU2 (n = 221) for BMI, SE, modeling, and stress measures (all P < 0.01) and physical activity (P = 0.001 FU and 0.09 FU2). EC was denoted for 53% and 57% at BL and FU2 respectively. BL to FU2 ecSI 2.0(TM) change was not significant when controlling for changes in stress or physical activity. However, compared to those with increased FU2 BMI, ecSI 2.0(TM) tended (P = 0.06) to increase when BMI was decreased or unchanged, even when controlling for BL BMI. BL to FU2 ecSI 2.0 change was inversely related to BMI change (P = 0.01). ecSI 2.0(TM) tended to decrease for control, but increase for intervention parents (P = 0.07; –0.34 vs. 1.05), but not when controlling for BMI change. CONCLUSIONS: An intervention with attention to EC congruent tenets showed modest effect on ecSI 2.0(TM) suggesting that successful programs require attributes that directly align with EC, which may be uniquely different from traditional nutrition education. Accurate EC intervention assessment required consideration of BMI change. FUNDING SOURCES: USDA, NIFA.

The Trends of Media Coverage about Libraries in Korea: Using Semantic Network Analysis of Portal News

Field: Social Sciences (Social Sciences)

Abstract The purpose of this study is to understand the trends and problems of media coverage about Korean libraries by selecting keywords from Korean portal news articles and conducting semantic network analysis. As a result, Korean news reports focus on public libraries rather than school and university libraries. Elsewhere, libraries’ lifelong learning program performance, such as cultural events and educational lectures, are overly biased on press release. In addition, news articles in all kinds of libraries are dominated by simple publicity about businesses or events rather than policy issues about library laws, budgets and manpower. Korea’s libraries reflected in the media are analyzed as cultural and social educational institutions rather than knowledge information centers.
In Reply: Aminophylline Study: Not Enough Patients?

Field: Medicine (Health Sciences)

In response to Dr Hornberger's inquiry about the power analysis of our study, patients excluded from the final statistical analysis were those who also required longer hospitalization rates, which raised the standard deviations for both groups considerably. These patients were removed from the study for either aminophylline toxicity or failure to respond to therapy. When the data for these cases were excluded, the standard deviation dropped to 0.82 and 0.53 for the aminophylline and placebo groups respectively, resulting in the relatively high power to detect a 1 day difference in hospitalization.
Assessing and improving co-creation in services: the customer-centric matrix

Field: Business, Management and Accounting (Social Sciences)

Purpose The strategy of co-creation with customers is a fast-growing topic within the academic community, which companies are trying to master. This study aims to elucidate the range of possible co-creation strategies and identify how service firms can assess and improve co-creation to reap the most benefits. Design/methodology/approach This study examines 13 companies from five service industries, using netnography to analyse how they approach co-creation. The firms’ co-creation strategy is analysed according to the forms of co-creation they choose and the type of activities involved in the value chain, primary, support and corporate social responsibility (CSR). Findings This study identifies three co-creation axes (C3) for companies: primary activities, support activities and CSR activities. Then, four levels of customer involvement (A4) are defined as follows: levels zero (await), one (advise), two (assist) and three (act). As such, this study positions firms according to the A4C3 customer-centric matrix. Practical implications In this co-creation benchmark, firms should use the A4C3 customer-centric matrix to understand their positions vis-à-vis competitors. This allows firms to establish an appropriate co-creation strategy for their services so that customers are the actors in their personalised service. Originality/value This study is the first to propose a framework through which a company can identify three types of co-creation activities (primary, secondary, CSR; C3), using it to increase co-creation and draw inspiration from other companies.
Simulation studies of errors of parameter estimates in pharmacokinetics.

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Pharmacokinetic parameters are indispensable for the development and evaluation of drugs. Therefore, they are required by international drug agencies and may influence relevant decisions. Their determination from experimental results is only possible with statistical errors. For the estimation of these errors only approximative procedures are available. A widespread approximation (information inequality) is based on specific assumptions which are invalid in practice. Erroneous estimations of unknown amount may consequently result. Alternative methods more adaptable to reality are simulation techniques with random numbers. This technique was used to calculate the statistical variability of parameter estimates for the usual compartment models. The results were compared with the variation of the parameter estimates from a descriptive model function recently developed. Adequate curves were predefined by appropriate parameter sets. Around these curves, a random generator simulated 500 data sequences. Fitting with the appertaining model function resulted in 500 sets of estimated parameters. The statistical behavior of the parameter estimates was investigated. The parameters computed by the fitting procedure--in the compartment models the rate constants--showed a large variation so that an estimate from a single data sequence does barely reproduce the "true" value of the parameter. In contrast, the parameters derived from the geometric properties of the fitted curves (e.g., area under curve, time and height of maximum) showed considerable less variation. As far as these investigations allow a conclusion, the latter parameters seem to be sufficiently reliable for practical purposes.
Cleared for the visual approach: Human factor problems in air carrier operations

Field: Decision Sciences (Social Sciences)

The study described herein, a set of 353 ASRS reports of unique aviation occurrences significantly involving visual approaches was examined to identify hazards and pitfalls embedded in the visual approach procedure and to consider operational practices that might help avoid future mishaps. Analysis of the report set identified nine aspects of the visual approach procedure that appeared to be predisposing conditions for inducing or exacerbating the effects of operational errors by flight crew members or controllers. Predisposing conditions, errors, and operational consequences of the errors are discussed. In a summary, operational policies that might mitigate the problems are examined.
Residue Depletion of Tritium-Labeled Ivermectin in the Muscle Tissues of Aquacultured Atlantic Salmon, Tilapia, and Catfish following Oral Treatment

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Abstract The residue depletion and metabolism profiles of tritium-labeled ivermectin in the muscle tissues of aquacultured Atlantic salmon Salmo salar, hybrid tilapia (Nile tilapia Oreochromis niloticus × Mozambique tilapia O. mossambicus; hereafter, “tilapia”) and channel catfish Ictalurus punctatus following oral treatment are reported. Fish were administered 3H-ivermectin at the dose level of 0.1 mg/kg of body weight (9–10 μ curies [Ci]) in a gel capsule via a stomach tube. At each postdose withdrawal time (1, 7, 14, 21, and 28 d), six fish of each species were sedated, euthanized, bled, and scaled, and fillets with adhering skin (except for catfish) were collected. The muscle fillets were homogenized in dry ice and an aliquot of each was extracted in acetonitrile followed by a high-performance liquid chromatographic analysis to determine the presence of parent ivermectin and its potential metabolites. The analysis of the muscle extracts revealed that the parent 3H-ivermectin is the major residue present for the three fish species studied. The results showed that the highest radioactive residue concentrations (ivermectin equivalents) of 21 and 6 ng/g were obtained on postdose day 1 for channel catfish and tilapia, respectively. For Atlantic salmon, the highest concentration of 14 ng/g was detected on day 7. By postdose day 21, the ivermectin radioactive residue depleted to less than 10 ng/g for all three species. No significant radioactive residue concentrations of metabolites were detected on any of the sampling days. These results suggest that parent ivermectin could serve as a marker residue to monitor its unauthorized use in Atlantic salmon, tilapia, and channel catfish.

Utility of 18 F-fluoroestradiol over 18 F-fluorodeoxyglucose positron emission tomography/computed tomography in the initial diagnosis of over 90 metastatic lesions in a patient with metastatic estrogen receptor–positive breast cancer

Field: Medicine (Health Sciences)

Approximately 6% of women with newly diagnosed breast cancer will present with metastatic disease. Proper staging workup and diagnosis of metastatic lesions is crucial prior to surgical treatment.18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) is often included in the staging workup of locally advanced breast cancer. Recently, PET/CT with 18F-fluoroestradiol (18F-FES), a radiolabeled form of estradiol that binds to the estrogen receptor, has been approved as an additional imaging technique for the detection of estrogen receptor-positive lesions in patients with metastatic breast cancer. Though the two have been shown to have comparable sensitivity for diagnosis of metastatic lesions, there is still much debate regarding when to use 18F-FES PET/CT over 18F-FDG PET/CT imaging. We present the case of a 68-year-old patient diagnosed with estrogen and progesterone receptor-positive invasive ductal carcinoma of the left breast. Her staging workup included an 18F-FDG PET/CT that did not demonstrate any evidence of metastatic lesions. Due to discordant imaging findings, the patient then underwent 18F-FES PET/CT, which demonstrated over 90 metastatic osseous lesions. This study highlights the utility of 18F-FES PET/CT over 18F-FDG PET/CT in diagnosis of metastatic osseous lesions in a patient with metastatic estrogen receptor-positive breast cancer.

Irradiation of Bypass Diodes up to 2.2E14 Neutron/cm$^{2}$ and 1.3 kGy for the FAIR Project

Field: Physics and Astronomy (Physical Sciences)

The FAIR project planned at G.S.I. (Germany) requires the construction of several superconducting accelerator rings. One of the two synchrotron rings, named SIS300, will have dipoles with a central field of 6 T and a ramp rate of 1 T/s. In order to protect these fast-ramping magnets in case of a quench, each of them must be equipped with a diode stack that bypasses the magnet in case it quenches. In order to save time and money on R&D, we decided to use the same diode type as that mounted in LHC magnets. These diodes were previously tested at 77 K up to a fast neutron fluence (F) of 2.8E13 n/cm 2 and a dose (D) of 2 kGy which are the expected radiation loads after 20 years of LHC operation. Having no definitive estimation of the losses in the SIS300, we arbitrarily targeted a fluence of 1E14 n/cm 2 . We irradiated six LHC type diodes at 77 K in six steps. The highest values measured were 1.31 kGy and 2.25E14 n/cm 2 . Before and after each irradiation step, the forward and reverse voltage characteristics of each diode were measured. This paper reports the results of these measurements, carried out at ITEP (Moscow).
A Systematic Review and Recommendation for Reporting of Surrogate Endpoint Evaluation Using Meta-analyses

Field: Medicine (Health Sciences)

Abstract Background Meta-analysis of randomized controlled trials (RCTs) has been widely conducted for the evaluation of surrogate endpoints in oncology, but little attention has been given to the adequacy of reporting and interpretation. This review evaluated the reporting quality of published meta-analyses on surrogacy evaluation and developed recommendations for future reporting. Methods We searched PubMed through August 2017 to identify studies that evaluated surrogate endpoints using the meta-analyses of RCTs in oncology. Both individual patient data (IPD) and aggregate data (AD) meta-analyses were included for the review. Results Eighty meta-analyses were identified: 22 used IPD and 58 used AD from multiple RCTs. We observed variability and reporting deficiencies in both IPD and AD meta-analyses, especially on reporting of trial selection, endpoint definition, study and patient characteristics for included RCTs, and important statistical methods and results. Based on these findings, we proposed a checklist and recommendations to improve completeness, consistency, and transparency of reports of meta-analytic surrogacy evaluation. We highlighted key aspects of the design and analysis of surrogate endpoints and presented explanations and rationale why these items should be clearly reported in surrogacy evaluation. Conclusions Our reporting of surrogate endpoint evaluation using meta-analyses (ReSEEM) guidelines and recommendations will improve the quality in reporting and facilitate the interpretation and reproducibility of meta-analytic surrogacy evaluation. Also, they should help promote greater methodological consistency and could also serve as an evaluation tool in the peer review process for assessing surrogacy research.
Quantitative Muscle Strength Testing: A Comparison of Job Strength Requirements and Actual Worker Strength Among Military Technicians

Field: Health Professions (Health Sciences)

In this study the authors investigate the percentage of mismatch between job demands and worker physical capacity in Utah National Guard mechanics. This population had demonstrated a higher incidence of low back trouble than other job descriptions reviewed. The authors utilized onsite still and videotape photography and a computerized biomechanical strength prediction model to assess loads on the lumbosacral spine due to various job tasks. Job demands were then compared to the actual physical capacity of the individual workers based on static strength testing in job-related positions. A load cell on the testing apparatus entered the force generated into a computer which averaged the force of the last three seconds of a five-second lift. It was determined that as much as a 38% mismatch existed within this population for some job tasks which these workers were exposed to. Suggestions for preventing job-related low back cumulative trauma disorders are presented, including: engineering redesign, worker selection programs, work hardening, and others.

Improving the vibration suppression capabilities of a magneto-rheological damper using hybrid active and semi-active control

Field: Engineering (Physical Sciences)

This paper presents a new hybrid active and semi-active control method for vibration suppression in flexible structures. The method uses a combination of a semi-active device and an active control actuator situated elsewhere in the structure to suppress vibrations. The key novelty is to use the hybrid controller to enable the magneto-rheological damper to achieve a performance as close to a fully active device as possible. This is achieved by ensuring that the active actuator can assist the magneto-rheological damper in the regions where energy is required. In addition, the hybrid active and semi-active controller is designed to minimize the switching of the semi-active controller. The control framework used is the immersion and invariance control technique in combination with sliding mode control. A two degree-of-freedom system with lightly damped resonances is used as an example system. Both numerical and experimental results are generated for this system, and then compared as part of a validation study. The experimental system uses hardware-in-the-loop to simulate the effect of both the degrees-of-freedom. The results show that the concept is viable both numerically and experimentally, and improved vibration suppression results can be obtained for the magneto-rheological damper that approach the performance of an active device.
