    Armstrong, Stephanie

    2017-12-01

    This review examines the screening instruments that are in existence today to identify commercially sexually exploited children. The instruments are compared and evaluated for their feasibility of use in an emergency department setting. Four electronic databases were searched to identify screening instruments that assessed solely for commercial sexual exploitation. Search terms included "commercially sexually exploited children," "CSEC," "domestic minor sex trafficking," "DMST," "juvenile sex trafficking," and "JST." Those terms were then searched in combination with each of the following: "tools," "instruments," "screening," "policies," "procedures," "data collection," "evidence," and "validity." Six screening instruments were found to meet the inclusion criteria. Variation among instruments included number of questions, ease of administration, information sources, scoring methods, and training information provided. Two instruments were determined to be highly feasible for use in the emergency department setting, those being the Asian Health Services and Banteay Srei's CSEC Screening Protocol and Greenbaum et al's CSEC/child sex trafficking 6-item screening tool. A current dearth of screening instruments was confirmed. It is recommended that additional screening instruments be created to include developmentally appropriate instruments for preadolescent children. Numerous positive features were identified within the instruments in this review and are suggested for use in future screening instruments, including succinctness, a simple format, easy administration, training materials, sample questions, multiple information sources, designation of questions requiring mandatory reporting, a straightforward scoring system, and an algorithm format.

    2008-01-01

    The second edition of Electronic Imaging in Astronomy: Detectors and Instrumentation describes the remarkable developments that have taken place in astronomical detectors and instrumentation in recent years – from the invention of the charge-coupled device (CCD) in 1970 to the current era of very large telescopes, such as the Keck 10-meter telescopes in Hawaii with their laser guide-star adaptive optics which rival the image quality of the Hubble Space Telescope. Authored by one of the world’s foremost experts on the design and development of electronic imaging systems for astronomy, this book has been written on several levels to appeal to a broad readership. Mathematical expositions are designed to encourage a wider audience, especially among the growing community of amateur astronomers with small telescopes with CCD cameras. The book can be used at the college level for an introductory course on modern astronomical detectors and instruments, and as a supplement for a practical or laboratory class.

    The Suprathermal Electron (STE) instrument, part of the IMPACT investigation on both spacecraft of NASA’s STEREO mission, is designed to measure electrons from ˜2 to ˜100 keV. This is the primary energy range for impulsive electron/3He-rich energetic particle events that are the most frequently occurring transient particle emissions from the Sun, for the electrons that generate solar type III radio emission, for the shock accelerated electrons that produce type II radio emission, and for the superhalo electrons (whose origin is unknown) that are present in the interplanetary medium even during the quietest times. These electrons are ideal for tracing heliospheric magnetic field lines back to their source regions on the Sun and for determining field line lengths, thus probing the structure of interplanetary coronal mass ejections (ICMEs) and of the ambient inner heliosphere. STE utilizes arrays of small, passively cooled thin window silicon semiconductor detectors, coupled to state-of-the-art pulse-reset front-end electronics, to detect electrons down to ˜2 keV with about 2 orders of magnitude increase in sensitivity over previous sensors at energies below ˜20 keV. STE provides energy resolution of Δ E/ E˜10 25% and the angular resolution of ˜20° over two oppositely directed ˜80°×80° fields of view centered on the nominal Parker spiral field direction.

    2005-01-01

    This work presents the obtained results in the research, development and construction of the electronic instrumentation required for the measurement of the essential characteristics of the nuclear radiation: The quantity of radiation and its energy components. With this information, many practical instruments can be developed and applied in different fields of science and technology. In this work, some instruments were developed for their application in the areas of medicine, industry, and particle physics research. Several measurement systems based on PIN type diodes are proposed for: a) the measurement of the operational characteristics of the X-ray machines and the X-rays emitted in medical radio-diagnostic, b) X-ray spectroscopy and c) radiation spectroscopy of charged particles. The contribution of this work is, precisely, the development of new instruments that use the PIN diode as the sensorial element. In this way, existing problems in nuclear instrumentation are overcame, specially in the fields of medical physics and particle physics. Likewise, different types of charge and current preamplifiers, with a high signal-to-noise ratio, were developed for these instruments. (Author)

In the studies of new scintillation techniques large area avalanche photodiodes were used successfully to tests numerous scintillators at liquid nitrogen temperature. The study of pure (undoped) NaI showed some intriguing effects dealing with non-proportionality of the light yield versus energy of γ-quanta and intrinsic energy resolution of the crystals, which may provide a deeper insight into origin of intrinsic resolution. A very high-energy resolution of 3.8% was measured for 662 keV γ-rays from a 137 Cs source. Moreover, very promising properties of pure NaI at room temperature were shown for the first time.

    Lin, S; Winocur-Arias, O; Slutzky-Goldberg, I

    2009-04-01

    Electronic Apex Locators (EAL) have become widely used in the last decade. The first apex locator was introduced in 1962, based on a constant electrical resistance (6.5 K.) between the oral mucosa and periodontal ligament. The first and second generations of EAL were inaccurate and could not detect the apex in the presence of conducting fluids. The third generation solved this problem by using two alternating frequencies and calculating the impedance between them. This provided reliable and accurate results in dry canals, or in the presence of blood, electrolytes or other fluid in the root canals, when the pulp was necrotic or when there was a perforation along the root. The Root ZX and Apit (Endex) are the most documented devices. The new fourth generation of apex locators is a diverse group: some use multifrequency currents, others use a "lookup matrix" rather than calculate the readings. Several of the newer EALs are smaller, and others connect to computers.

    Steiner, Nyle A.

    2004-05-01

    The Electronic Valve Instrument (EVI) is an electronic musical wind instrument with playing techniques similar to that of a trumpet. Invented by Nyle Steiner in the early 1970's, it was designed to give the performer control of dynamics from breath pressure and the ability to make a humanly generated vibrato. Other musical paramaters can be controlled as well. It has a playing range of seven octaves (similar to that of a piano). When musical lines are played using this instrument (controller) connected to an electronic music synthesizer, the sound is much more natural sounding and expressive than when a normal musical keyboard is used. The evolution of this instrument from the pre-Midi era to it latest Midi configuration, principles of operation, synthesizer programming, and its wide use in movie and TV scoring will be discussed. The EVI has played featured musical lines in many major movie soundtracks and TV shows such as Apocalypse Now, Witness, Dead Poets Society, Fatal Attraction, No Way Out, Gorillas in the Mist, and many others. The EVI design has also been adapted as an Electronic Woodwind Instrument (EWI) by Nyle Steiner and has been manufactured and sold worldwide by the AKAI Co. in Japan.

    PURPOSE: Collecting daily information on a series of similar, recurring events such as menstrual bleeding, headaches, or insulin levels using paper instruments is subject to problems such as missing or incorrectly recorded data, and retrospective data entry. The authors are developing and evaluating electronic data collection using hand-held personal computers (H/PC) for a variety of health-related applications, including tracking premenstrual syndrome (PMS), fertility awareness, and headaches, to improve accuracy and timeliness of data collection.METHODS: ProCycle is a prototype electronic diary for collection of daily data on menstrual bleeding, medications, and health symptoms. In a 3-month pilot test in 25 regularly cycling women, we compared its performance with a paper calendar regarding missing and incorrect data, data entry lag, data cleaning time, and users' preferences with respect to factors such as remembering to enter data, convenience, and overall preference. Additional programs for PMS, fertility, and headaches are being field tested on subjects from the Boston and New York areas, comparing performance with paper versions.RESULTS: In the pilot test, missing data occurred less frequently with ProCycle than with paper, particularly for any days with missing symptoms (4% vs. 35%, p instruments on an H/PC provide an efficient, accurate method of data collection, applicable to a number of areas of health-related research involving daily data collection.

    Although screening for child abuse at emergency departments (EDs) increases the detection rate of potential child abuse, an accurate instrument is lacking. This study was designed to measure the accuracy of a screening instrument for detection of potential child abuse used in EDs. In a prospective cohort study at three Dutch EDs, a 6-item screening instrument for child abuse, Escape, was completed for each child visiting the ED. The data from the completed Escape instrument was used to calculate sensitivity, specificity, and the positive/negative predictive value per item. The clinical notes and conclusions of the screen instruments of all potentially abused children reported to the hospitals' Child Abuse Teams were collected and reviewed by an expert panel. A logistic regression model was used to evaluate the predictors of potential abuse. Completed Escape instruments were available for 18,275 ED visits. Forty-four of the 420 children with a positive screening result, and 11 of the 17,855 children with a negative result were identified as potentially abused. Sensitivity of the Escape instrument was 0.80 and specificity was 0.98. Univariate logistic regression showed that potentially abused children were significantly more likely to have had an aberrant answer to at least one of the items, OR=189.8, 95% CI [97.3, 370.4]. Most of the children at high risk for child abuse were detected through screening. The Escape instrument is a useful tool for ED staff to support the identification of those at high risk for child abuse. Copyright © 2013 The Authors. Published by Elsevier Ltd..

    International Nuclear Information System (INIS)

    1978-10-01

    The electronics department at Risoe National Laboratory, Denmark, comprises about 80 people and is made up of essentially two main divisions. One deals with the provision of instrumentation and measurement expertise for the different groups at Risoe who conduct basic research or technological R and D. This division employs a group of scientific electronics consultants, a production group, a maintenance facility and a central instrument pool for the complete site. The other division, whose work is reported here, is engaged in both basic and applied research in topics and areas of direct interest to the department itself.

  11. Electronic Instrumentations for High Energy Particle Physics and Neutrino Physics

    CERN Document Server

    AUTHOR|(INSPIRE)INSPIRE-00452332

    The present dissertation describes design, qualification and operation of several electronic instrumentations for High Energy Particle Physics experiments (LHCb) and Neutrino Physics experiments (CUORE and CUPID). Starting from 2019, the LHCb experiment at the LHC accelerator will be upgraded to operate at higher luminosity and several of its detectors will be redesigned. The RICH detector will require a completely new optoelectronic readout system. The development of such system has already reached an advanced phase, and several tests at particle beam facilities allowed to qualify the performance of the entire system. In order to achieve a higher stability and a better power supply regulation for the front-end chip, a rad-hard low dropout linear regulator, named ALDO, has been developed. Design strategies, performance tests and results from the irradiation campaign are presented. In the Neutrino Physics field, large-scale bolometric detectors, like those adopted by CUORE and its future upgrade CUPID, offer u...

  12. An Electron Beam Profile Instrument Based on FBGs

    Full Text Available Along with the dose rate and the total irradiation dose measurements, the knowledge of the beam localization and the beam profile/energy distribution in the beam are parameters of interest for charged particle accelerator installations when they are used in scientific investigations, industrial applications or medical treatments. The transverse profile of the beam, its position, its centroid location, and its focus or flatness depend on the instrument operating conditions or on the beam exit setup. Proof-of-concept of a new type of charged particle beam diagnostics based on fiber Bragg gratings (FBGs was demonstrated. Its operating principle relies on the measurement of the peak wavelength changes for an array of FBG sensors as function of the temperature following the exposure to an electron beam. Periodically, the sensor irradiation is stopped and the FBG are force cooled to a reference temperature with which the temperature influencing each sensor during beam exposure is compared. Commercially available FBGs, and FBGs written in radiation resistant optical fibers, were tested under electron beam irradiation in order to study their possible use in this application.

  13. On DESTINY Science Instrument Electrical and Electronics Subsystem Framework

    Future space missions are going to require large focal planes with many sensing arrays and hundreds of millions of pixels all read out at high data rates'' . This will place unique demands on the electrical and electronics (EE) subsystem design and it will be critically important to have high technology readiness level (TRL) EE concepts ready to support such missions. One such omission is the Joint Dark Energy Mission (JDEM) charged with making precise measurements of the expansion rate of the universe to reveal vital clues about the nature of dark energy - a hypothetical form of energy that permeates all of space and tends to increase the rate of the expansion. One of three JDEM concept studies - the Dark Energy Space Telescope (DESTINY) was conducted in 2008 at the NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. This paper presents the EE subsystem framework, which evolved from the DESTINY science instrument study. It describes the main challenges and implementation concepts related to the design of an EE subsystem featuring multiple focal planes populated with dozens of large arrays and millions of pixels. The focal planes are passively cooled to cryogenic temperatures (below 140 K). The sensor mosaic is controlled by a large number of Readout Integrated Circuits and Application Specific Integrated Circuits - the ROICs/ASICs in near proximity to their sensor focal planes. The ASICs, in turn, are serviced by a set of "warm" EE subsystem boxes performing Field Programmable Gate Array (FPGA) based digital signal processing (DSP) computations of complex algorithms, such as sampling-up-the-ramp algorithm (SUTR), over large volumes of fast data streams. The SUTR boxes are supported by the Instrument Control/Command and Data Handling box (ICDH Primary and Backup boxes) for lossless data compression, command and low volume telemetry handling, power conversion and for communications with the spacecraft. The paper outlines how the JDEM DESTINY concept

    Electronic dance music (EDM) festivals are increasingly common and psychoactive substance use is prevalent. Although prehospital care can obviate the transfer of many attendees to health care facilities (HCFs), little is known regarding the emergency department (ED) burden of patients presenting from EDM festivals. This study describes the patient volume, length of stay (LOS), and presenting complaints of patients from a 3-day EDM festival in close proximity to an area ED. Medical charts of patients presenting to one HCF from an EDM festival were reviewed for substances used, ED LOS, and sedative medications administered. Additionally, preparedness techniques are described. Over the 3-day festival, 28 patients presented to the ED (median age 21 years; range 18-29 years). Twenty-five had complaints related to substance use including ethanol (n = 18), "molly" or "ecstasy" (n = 13), and marijuana (n = 8). Three patients required intensive care or step-down unit admission for endotracheal intubation, rhabdomyolysis, and protracted altered mental status. The median LOS for discharged patients was 265 min (interquartile range 210-347 min). Eleven patients required the use of sedative medications, with cumulative doses of 42 mg of lorazepam and 350 mg of ketamine. All patients presented within the hours of 5:00 pm and 2:15 am. The majority of ED visits from an EDM festival were related to substance use. ED arrival times clustered during the evening and were associated with prolonged LOS. Few patients required hospital admission, but admitted patients required high levels of care. HCFs should use these data as a guide in planning for future events. Copyright © 2017 Elsevier Inc.

    A proper measurement of the relevant single and two-phase flow parameters is the basis for the understanding of many complex thermal-hydraulic processes. Reliable instrumentation is therefore necessary for the interaction between analysis and experiment especially in the field of nuclear safety research where postulated accident scenarios have to be simulated in experimental facilities and predicted by complex computer code systems. The so-called conventional instrumentation for the measurement of e. g. pressures, temperatures, pressure differences and single phase flow velocities is still a solid basis for the investigation and interpretation of many phenomena and especially for the understanding of the overall system behavior. Measurement data from such instrumentation still serves in many cases as a database for thermal-hydraulic system codes. However some special instrumentation such as online concentration measurement for boric acid in the water phase or for non-condensibles in steam atmosphere as well as flow visualization techniques were further developed and successfully applied during the recent years. Concerning the modeling needs for advanced thermal-hydraulic codes, significant advances have been accomplished in the last few years in the local instrumentation technology for two-phase flow by the application of new sensor techniques, optical or beam methods and electronic technology. This paper will give insight into the current state of instrumentation technology for safety-related thermohydraulic experiments. Advantages and limitations of some measurement processes and systems will be indicated as well as trends and possibilities for further development. Aspects of instrumentation in operating reactors will also be mentioned.

    Photoelectron peaks in the 20-30 eV energy range are commonly observed in planetary atmospheres (Earth, Mars, Titan...), produced by the intense photoionization from solar 30.4 nm photons. At Mars, these photoelectrons result from the ionization of CO2 and O atmospheric neutrals, and are known to escape the planet down its tail, making them tracers for the atmospheric escape (Frahm et al., 2006). Furthermore, their presence or absence allows us to define the so-called PhotoElectron Boundary (PEB), that separates the sunlit photoelectron-dominated ionosphere from the solar wind controlled environment, as initially observed by the Mars Global Surveyor (MGS) MAG/ER instrument (Mitchell et al. (2000, 2001). We provide here a detailed statistical analysis of the location and properties of the PEB based on the Mars Atmosphere and Volatile Evolution (MAVEN) mission electron and magnetic field data. Our dataset includes 1696 dayside PEB crossings obtained from September 2014 until May 2016 (the observations of escaping photoelectrons in the wake being not included). The PEB appears as mostly sensitive to the solar wind dynamic and crustal magnetic fields pressures, for which a quantitative dependance is derived and compared with two other important boundaries : the bow shock and magnetic pileup boundary. The PEB altitude is highly variable, leading to a variable wake cross section for escape (up to +- 50%), which is important for deriving global escape rates from in situ photoelectron escape rates. The PEB is not always sharp, and is, despite a strong variability, characterized on average by : a magnetic field topology typical for the edge of the Magnetic Pile Up Region above it, more field aligned fluxes above than below, and a clear change of the altitude dependence of both electron fluxes and total density (that appears different from the ionopause). The PEB thus appears as a transition region between two plasma and field configurations which is determined by the

  18. Evolutionary developments in x ray and electron energy loss microanalysis instrumentation for the analytical electron microscope

    Science.gov (United States)

    Zaluzec, Nester J.

    Developments in instrumentation for both X ray Dispersive and Electron Energy Loss Spectroscopy (XEDS/EELS) over the last ten years have given the experimentalist a greatly enhanced set of analytical tools for characterization. Microanalysts have waited for nearly two decades now in the hope of getting a true analytical microscope and the development of 300 to 400 kV instruments should have allowed us to attain this goal. Unfortunately, this has not generally been the case. While there have been some major improvements in the techniques, there has also been some devolution in the modern AEM (Analytical Electron Microscope). In XEDS, the majority of today's instruments are still plagued by the hole count effect, which was first described in detail over fifteen years ago. The magnitude of this problem can still reach the 20 percent level for medium atomic number species in a conventional off-the-shelf intermediate voltage AEM. This is an absurd situation and the manufacturers should be severely criticized. Part of the blame, however, also rests on the AEM community for not having come up with a universally agreed upon standard test procedure. Fortunately, such a test procedure is in the early stages of refinement. The proposed test specimen consists of an evaporated Cr film approx. 500 to 1000A thick supported upon a 3mm diameter Molybdenum 200 micron aperture.

    The present study deals with the evaluation of the electronic tongue multisensor system as an analytical tool for the rapid assessment of taste and flavour of beer. Fifty samples of Belgian and Dutch beers of different types (lager beers, ales, wheat beers, etc.), which were characterized with respect to the sensory properties, were measured using the electronic tongue (ET) based on potentiometric chemical sensors developed in Laboratory of Chemical Sensors of St. Petersburg University. The analysis of the sensory data and the calculation of the compromise average scores was made using STATIS. The beer samples were discriminated using both sensory panel and ET data based on PCA, and both data sets were compared using Canonical Correlation Analysis. The ET data were related to the sensory beer attributes using Partial Least Square regression for each attribute separately. Validation was done based on a test set comprising one-third of all samples. The ET was capable of predicting with good precision 20 sensory attributes of beer including such as bitter, sweet, sour, fruity, caramel, artificial, burnt, intensity and body.

    ESPRESSO is an ultra-stable fiber-fed spectrograph designed to combine incoherently the light coming from up to 4 Unit Telescopes of the ESO VLT. From the Nasmyth focus of each telescope the light, through an optical path, is fed by the Coudé Train subsystems to the Front End Unit placed in the Combined Coudé Laboratory. The Front End is composed by one arm for each telescope and its task is to convey the incoming light, after a calibration process, into the spectrograph fibers. To perform these operations a large number of functions are foreseen, like motorized stages, lamps, digital and analog sensors that, coupled with dedicated Technical CCDs (two per arms), allow to stabilize the incoming beam up to the level needed to exploit the ESPRESSO scientific requirements. The Instrument Control Electronics goal is to properly control all the functions in the Combined Coudé Laboratory and the spectrograph itself. It is fully based on a distributed PLC architecture, abandoning in this way the VME-based technology previously adopted for the ESO VLT instruments. In this paper we will describe the ESPRESSO Instrument Control Electronics architecture, focusing on the distributed layout and its interfaces with the other ESPRESSO subsystems.

    2008-01-01

    Full Text Available Aim: To evaluate teaching and practice in medical college ophthalmology departments in a representative Indian state and changes following provision of modern instrumentation and training. Study Type: Prospective qualitative study. Materials and Methods: Teaching and practice in all medical colleges in the state assessed on two separate occasions by external evaluators. Preferred criteria for training and care were pre-specified. Methodology included site visits to document functioning and conduct interviews. Assessments included resident teaching, use of instrumentation provided specifically for training and standard of eye care. The first evaluation (1998 was followed by provision of modern instrumentation and training on two separate occasions, estimated at Rupees 34 crores. The follow-up evaluation in 2006 used the same methodology as the first. Results: Eight departments were evaluated on the first occasion; there were 11 at the second. On the first assessment, none of the programs met the criteria for training or care. Following the provision of modern instrumentation and training, intraocular lens usage increased dramatically; but the overall situation remained essentially unchanged in the 8 departments evaluated 8 years later. Routine comprehensive eye examination was neither taught nor practiced. Individually supervised surgical training using beam splitters was not practiced in any program; neither was modern management of complications or its teaching. Phacoemulsification was not taught, and residents were not confident of setting up practice. Instruments provided specifically for training were not used for that purpose. Students reported that theoretical teaching was good. Conclusions: Drastic changes in training, patient care and accountability are needed in most medical college ophthalmology departments.

    We are developing a transmission electron microscope that operates at extremely low electron energies, 0–40 eV. We call this technique eV-TEM. Its feasibility is based on the fact that at very low electron energies the number of energy loss pathways decreases. Hence, the electron inelastic mean free path increases dramatically. eV-TEM will enable us to study elastic and inelastic interactions of electrons with thin samples. With the recent development of aberration correction in cathode lens instruments, a spatial resolution of a few nm appears within range, even for these very low electron energies. Such resolution will be highly relevant to study biological samples such as proteins and cell membranes. The low electron energies minimize adverse effects due to radiation damage. - Highlights: • We present a new way of performing low energy transmission electron microscopy in an aberration corrected LEEM/PEEM instrument. • We show a proof of principle where we measure transmitted electrons through a suspended graphene monolayer with a preliminary setup. • We present an improved setup design that provides better control of the incident electron beam.

    All the available nightside electron data obtained during circular orbits at Mars from the Phobos-2 Hyperbolic Retarded Potential Analyzer (HARP) instrument have been examined in detail and are summarized in this paper. An electron flux component with energies exceeding that of the unperturbed solar wind was observed inside the magnetosheath, indicating the presence of acceleration mechanism(s). The character of the electron fluxes measured in the magnetotail cannot be classified in any simple manner, however, there is a correlation between the electron fluxes measured well inside this region and the unperturbed solar wind ram pressure.

    Full Text Available Background: The aim of this study was to compare root surface characteristic following root planing with various hand and power driven instruments. Materials and Methods: A total of 20 single rooted teeth were used in this study, of which two specimens were used as control (no instrumentation done and remaining 18 specimens were equally divided into three groups. Specimens from each group were then subjected to root planing by one of the following instruments: (1 a Gracey curette (2 Ultrasonic tip and (3 a Rotary bur. In each case, the time required for scaling and root planing was measured. After treatment, the specimens were observed under scanning electron microscope and surface roughness was measured by using Roughness and loss of tooth substance index (RLTSI. Results: The mean RLTSI scores for Gracey curette, ultrasonic and rotary instrument group were 2.5, 2.0 and 0.667 respectively. The mean scores of time spent for scaling and root planing by Gracey curette, ultrasonic and rotary instrument group in seconds were 42.50, 35.83 and 54.50. Conclusion: All the three instruments namely Gracey curette, Ultrasonic tip and Rotary bur were effective in mechanical debridement of root surface. The results favoured the use of rotary instruments for root planing to achieve smooth clean root surface; however, the use of rotary instrument was more time consuming which might limit its use in clinical practice.

    this whiteboard for four months nurses, but not physicians, spend more of their time with the patients. With the electronic whiteboard, nurses spend 28% of their time in patient rooms and physicians 20%. Importantly, the changes facilitated by the electronic whiteboard are also dependent on implementation issues......, existing work practices, and the clinicians’ experience. Another change in the work practices is distributed access to whiteboard information from the computers in patient rooms. A decrease in the mental workload of the coordinating nurse was envisaged but has not emerged. Achieving more changes appears......Electronic whiteboards are introduced at emergency departments (EDs) to improve work practices.

    We developed a communication instrument to be used in the Emergency Department (ED) and hypothesized that use of this guide would increase patient comprehension of and satisfaction with care. This multi-site trial enrolled 643 patients in treatment and control groups. Comprehension of care was assessed by chart review and satisfaction measured via validated survey. Use of the instrument was not associated with improvements in patient knowledge about their care, with a mean of 4.6 (95% CI: 4.8-5.8) comprehension defects in the control group and 4.4 (95% CI: 3.9-4.9) in the treatment group. There was no significant effect on patient satisfaction 76.4% versus 76.9%, p=0.34. Elderly patients in both groups were found to have 1.1 (ppatients. Patients frequently misunderstand medical care in the ED. Comprehension decreases with increasing age. An isolated communication instrument does not improve satisfaction with or understanding of the care received. Providing a structured place for providers and patients to record details of care does not seem to improve satisfaction with or comprehension of care. Interventions that focus on communication skills and face time with patients may prove more effective. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Assessing local health departments' (LHDs') informatics capacities is important, especially within the context of broader, systems-level health reform. We assessed a nationally representative sample of LHDs' adoption of information systems and the factors associated with adoption and implementation by examining electronic health records, health information exchange, immunization registry, electronic disease reporting system, and electronic laboratory reporting. We used data from the National Association of County and City Health Officials' 2013 National Profile of LHDs. We performed descriptive statistics and multinomial logistic regression for the five implementation-oriented outcome variables of interest, with three levels of implementation (implemented, plan to implement, and no activity). Independent variables included infrastructural and financial capacity and other characteristics associated with informatics capacity. Of 505 LHDs that responded to the survey, 69 (13.5%) had implemented health information exchanges, 122 (22.2%) had implemented electronic health records, 245 (47.5%) had implemented electronic laboratory reporting, 368 (73.0%) had implemented an electronic disease reporting system, and 416 (83.8%) had implemented an immunization registry. LHD characteristics associated with health informatics adoption included provision of greater number of clinical services, greater per capita public health expenditures, health information systems specialists on staff, larger population size, decentralized governance system, one or more local boards of health, metropolitan jurisdiction, and top executive with more years in the job. Many LHDs lack health informatics capacity, particularly in smaller, rural jurisdictions. Cross-jurisdictional sharing, investment in public health informatics infrastructure, and additional training may help address these shortfalls.

    The objective was to evaluate the diagnostic accuracy of five health literacy screening instruments in emergency department (ED) patients: the Rapid Evaluation of Adult Literacy in Medicine-Revised (REALM-R), the Newest Vital Sign (NVS), Single Item Literacy Screens (SILS), health numeracy, and physician gestalt. A secondary objective was to evaluate the feasibility of these instruments as measured by administration time, time on task, and interruptions during test administration. This was a prospective observational cross-sectional study of a convenience sampling of adult patients presenting during March 2011 and February 2012 to one urban university-affiliated ED. Subjects were consenting non-critically ill, English-speaking patients over the age of 18 years without aphasia, dementia, mental retardation, or inability to communicate. The diagnostic test characteristics of the REALM-R, NVS, SILS, health numeracy, and physician gestalt were quantitatively assessed by using the short Test of Functional Health Literacy in Adults (S-TOFHLA). A score of 22 or less was the criterion standard for limited health literacy (LHL). A total of 435 participants were enrolled, with a mean (±SD) age of 45 (±15.7) years, and 18% had less than a high school education. As defined by an S-TOFHLA score of 22 or less, the prevalence of LHL was 23.9%. In contrast, the NVS, REALM-R, and physician gestalt identified 64.8, 48.5, and 35% of participants as LHL, respectively. A normal NVS screen was the most useful test to exclude LHL, with a negative likelihood ratio of 0.04 (95% confidence interval [CI] = 0.01 to 0.17). When abnormal, none of the screening instruments, including physician gestalt, significantly increased the posttest probability of LHL. The NVS and REALM-R require 3 and 5 minutes less time to administer than the S-TOFHLA. Administration of the REALM-R is associated with fewer test interruptions. One-quarter of these ED patients had marginal or inadequate health

    The DAPNIA is a department of CEA, its main characteristic is to manage scientific teams working on astrophysics, nuclear physics, elementary particles and instrumentation. Every 2 years DAPNIA's activities are submitted to an evaluation made by a scientific committee whose members are experts independent from CEA. This committee reviews the work done, gives an opinion about the options chosen for the projects to come and writes out a report. In 1997 the committee had a very positive opinion of the work done by DAPNIA teams. The contributions to various and important national or international programs have been successful, we can quote: Ulysse mission, soho, iso, integral for spatial programs, aleph, delphi, H1 at Hera, atlas, cms, na48, nomad, babar, antares for particle physics and spiral, smc, compass for nuclear physics. The committee advises DAPNIA to favour more contacts between the theoreticians and the experimentalists who work on quantum chromodynamics and hadron physics. The committee shows its concern about improving the balance between the means dedicated to instrumentation designing and those dedicated to the analysis and interpretation of the experimental data collected.

    The Laser Applications in Materials Processing (LAMP) instrument is a new end-station for soft X-ray imaging, high-field physics, and ultrafast X-ray science experiments that is available to users at the Linac Coherent Light Source (LCLS) free-electron laser. While the instrument resides in the Atomic, Molecular and Optical science hutch, its components can be used at any LCLS beamline. The end-station has a modular design that provides high flexibility in order to meet user-defined experimental requirements and specifications. The ultra-high-vacuum environment supports different sample delivery systems, including pulsed and continuous atomic, molecular, and cluster jets; liquid and aerosols jets; and effusive metal vapor beams. It also houses movable, large-format, high-speed pnCCD X-ray detectors for detecting scattered and fluorescent photons. Multiple charged-particle spectrometer options are compatible with the LAMP chamber, including a double-sided spectrometer for simultaneous and even coincident measurements of electrons, ions, and photons produced by the interaction of the high-intensity X-ray beam with the various samples. Here we describe the design and capabilities of the spectrometers along with some general aspects of the LAMP chamber and show some results from the initial instrument commissioning.

    1.1 This practice describes procedures for evaluating the following performance characteristics of ultrasonic pulse-echo examination instruments and systems: Horizontal Limit and Linearity; Vertical Limit and Linearity; Resolution - Entry Surface and Far Surface; Sensitivity and Noise; Accuracy of Calibrated Gain Controls. Evaluation of these characteristics is intended to be used for comparing instruments and systems or, by periodic repetition, for detecting long-term changes in the characteristics of a given instrument or system that may be indicative of impending failure, and which, if beyond certain limits, will require corrective maintenance. Instrument characteristics measured in accordance with this practice are expressed in terms that relate to their potential usefulness for ultrasonic testing. Instrument characteristics expressed in purely electronic terms may be measured as described in E1324. 1.2 Ultrasonic examination systems using pulsed-wave trains and A-scan presentation (rf or video) may be ev...

    A Hybrid Photon Detector (HPD) is currently manufactured in the framework of the tests of LHC-B collaboration. These extremely fast and sensible detectors (95% efficiency and 1 ns time accuracy for a single electron) could be utilized in many other applications: long base neutrino oscillations and possibly, HELLAZ. The model consists of an array of 2,048 1 x 1 mm 2 on Si strips of 50 mm thickness placed in glass cylinders of 127 mm diameter provided with Si windows and containing focalization electrodes. The electron circuits on 16 VA3 readout ceramic chips where designed, realized and tested. The stainless steel base card provided with 40 vacuum holes was already realised. The first production tests of visible light bi-alkali photocathodes operating in high vacuum will be performed soon. The design of the RICH2 counter (covering polar angles from 12 to 120 mrad) has been modified by turning the 120 mrad mirror to increase the spectrometer luminosity, i.e. to increase the length of the radiation path in gas by a factor of two. A second mirror sends the image in a region behind the magnetic field return, a region well-shielded from the LHC interaction zone. This design will provided 28 points for a β = 1 tracks and an angular uncertainty of 0.34 mrad per point. To cover the entire image 115 HPD will be necessary. The reconstruction of the complex systems of rings has been recently accomplished for events typical for RICH2, downstream, to discriminate between pions and kaons between 16 and 180 GeV/c. A simulation of 3,068 tracks has produced only 19 erroneous identifications, i.e. 0.6%. Another, simulation of 1,989 tracks with the RICH upstream resulted in 39 erroneous π/K identification, i.e. 2%. The report presents also the long base RICH experiment for detecting neutrino oscillations. A new version of 100 m length and 18.6 m diameter (27 kt of water) provided with HPDs of 250 mm diameter with 85 6 x 6 mm 2 arrays has been designed. Fifty such detectors will be

    2008-01-01

    Safety has always been one of the principal goals in teaching laboratories. Laboratories cannot serve their educational purpose when accidents occur. The leadership of department heads has a major impact on laboratory safety, so this study discusses the factors affecting safety leadership in teaching laboratories. This study uses a mail survey to explore the perceived safety leadership in electrical and electronic engineering departments at Taiwanese universities. An exploratory factor analysis shows that there are three main components of safety leadership, as measured on a safety leadership scale: safety controlling, safety coaching, and safety caring. The descriptive statistics also reveals that among faculty, the perception of department heads' safety leadership is in general positive. A two-way MANOVA shows that there are interaction effects on safety leadership between university size and instructor age; there are also interaction effects between presence of a safety committee and faculty gender and faculty age. It is therefore necessary to assess organizational factors when determining whether individual factors are the cause of differing perceptions among faculty members. The author also presents advice on improving safety leadership for department heads at small universities and at universities without safety committees.

    UCLA's Electron Losses and Fields Investigation (ELFIN) is a 3U+ CubeSat mission designed to study relativistic particle precipitation in Earth's polar regions from Low Earth Orbit. Upon its 2018 launch, ELFIN will aim to address an important open question in Space Physics: Are Electromagnetic Ion-Cyclotron (EMIC) waves the dominant source of pitch-angle scattering of high-energy radiation belt charged particles into Earth's atmosphere during storms and substorms? Previous studies have indicated these scattering events occur frequently during storms and substorms, and ELFIN will be the first mission to study this process in-situ.Paramount to ELFIN's success is its instrument suite consisting of an Energetic Particle Detector (EPD) and a Fluxgate Magnetometer (FGM). The EPD is comprised of two collimated solid-state detector stacks which will measure the incident flux of energetic electrons from 50 keV to 4 MeV and ions from 50 keV to 300 keV. The FGM is a 3-axis magnetic field sensor which will capture the local magnetic field and its variations at frequencies up to 5 Hz. The ELFIN spacecraft spins perpendicular to the geomagnetic field to provide 16 pitch-angle particle data sectors per revolution. Together these factors provide the capability to address the nature of radiation belt particle precipitation by pitch-angle scattering during storms and substorms.ELFIN's instrument development has progressed into the late Engineering Model (EM) phase and will soon enter Flight Model (FM) development. The instrument suite is currently being tested and calibrated at UCLA using a variety of methods including the use of radioactive sources and applied magnetics to simulate orbit conditions during spin sectoring. We present the methods and test results from instrument calibration and performance validation.

    The paper describes an operation principle of odour nuisance monitoring network in a city agglomeration. Moreover, it presents the results of investigation on ambient air quality with respect to odour obtained during six-month period. The investigation was carried out using a network comprised of six prototypes of electronic nose and Nasal Ranger field olfactometers employed as a reference method. The monitoring network consisted of two measurement stations localized in a vicinity of crude oil processing plant and four stations localized near the main emitters of volatile odorous compounds such as sewage treatment plant, municipal landfill, phosphatic fertilizer production plant. The electronic nose prototype was equipped with a set of six semiconductor sensors by FIGARO Co. and one PID-type sensor. The field olfactometers were utilized for determination of mean concentration of odorants and for calibration of the electronic nose prototypes in order to provide their proper operation. Mean monthly values of odour concentration depended on the site of measurement and on meteorological parameters. They were within 0 - 6.0 ou/m3 range. Performed investigations revealed the possibility of electronic nose instrument application as a tool for monitoring of odour nuisance.

    To adapt the four-dimensional Gambling Motives Questionnaire-Revised (GMQ-R) to measure the motivation for engaging in electronic gaming, and to validate the internal structure and investigate the criterion validity of the new Electronic Gaming Motives Questionnaire (EGMQ). The GMQ-R was adapted to measure motivation for playing video games and the new instrument was tested on a sample of Norwegian conscripts selected randomly from the pool of conscripts who started their military service between 2013 and 2015. The questionnaire was administered to all those who had played video games during the last 6 months and consisted of 853 gamers (86.8% men, mean age = 19.4 years). All participants completed the EGMQ, as well as other measures of gaming behaviour, gaming problems, boredom, loneliness and depression. The confirmatory factor analyses showed that the proposed EGMQ (measuring enhancement, coping, social and self-gratification motives) displayed satisfactory fit and internal consistency. Hierarchical regression analyses showed that gender emerged as a significant predictor (P gaming, loss of control and gaming problems) and the first step explained between 1 and 6.1% of the variance in the gaming behaviours. In the second step the four motivational dimensions explained an additional 5.8-38.8% of the variance. Coping and self-gratification predicted gaming problems (P Gaming Motives Questionnaire is a valid instrument for measuring motives for gaming. © 2017 Society for the Study of Addiction.

    1963-01-01

    This book comes from work carried out at the International Atomic Energy Agency. It includes suggestions and recommendations of consultants from eleven countries made during a meeting at Agency headquarters in Vienna on 18 - 20 December 1961, and comments received afterwards on a draft recommendation. It is intended to serve as a guide for the Agency in purchasing equipment for use in tropical countries but not as a strict regulation to be followed in all cases. Suitable alternative materials and techniques are not precluded, but they shall be used only with the consent of the Agency. Before making its purchases the Agency will examine nuclear electronic equipment to find what is best and most suitable to meet difficult environmental conditions of tropical countries (Appendix B). Wherever possible it will recommend suitable air-conditioning systems. An attempt is made in this book to base recommendations on the accepted international procedures (technology and terminology) that are published by the International Electrotechnical Commission (IEC). Because rapidly advancing technology and the large amount of work being done in this field will very quickly make this book obsolete, an effort will be made to revise it in the future. Emphasis is made on the need to maintain requirements at limits that are restrictive. The purpose is to avoid abnormally high fabrication costs and to allow the Agency to select commercially manufactured instruments that best meet severe environmental conditions because of sound engineering design and use of first-quality materials and components. The section called 'Climatic conditions' has two purposes. The first is to tell manufacturers of the severity of conditions. The second is to describe conditions in particular locations. So that the manufacturer will be even more precisely informed of exact climatic conditions in which his products must perform, he will be provided with information from a questionnaire sent by the Agency to each

    In this study, we introduce a model to characterize electron scattering in an electrostatic analyzer. We show that electrons between 0.5 and 30 keV scatter from internal surfaces to produce a response up to ~20% of the ideal, unscattered response. We compare our model results to laboratory data from the Jovian Auroral Distribution Experiment-Electron sensor onboard the NASA Juno mission. Our model reproduces the measured energy-angle response of the instrument well. Understanding and quantifying this scattering process is beneficial to the analysis of scientific data as well as future instrument optimization.

    2009-08-01

    The Department of Energy and its contractors store and process massive quantities of sensitive information to accomplish national security, energy, science, and environmental missions. Sensitive unclassified data, such as personally identifiable information (PII), official use only, and unclassified controlled nuclear information require special handling and protection to prevent misuse of the information for inappropriate purposes. Industry experts have reported that more than 203 million personal privacy records have been lost or stolen over the past three years, including information maintained by corporations, educational institutions, and Federal agencies. The loss of personal and other sensitive information can result in substantial financial harm, embarrassment, and inconvenience to individuals and organizations. Therefore, strong protective measures, including data encryption, help protect against the unauthorized disclosure of sensitive information. Prior reports involving the loss of sensitive information have highlighted weaknesses in the Department's ability to protect sensitive data. Our report on Security Over Personally Identifiable Information (DOE/IG-0771, July 2007) disclosed that the Department had not fully implemented all measures recommended by the Office of Management and Budget (OMB) and required by the National Institute of Standards and Technology (NIST) to protect PII, including failures to identify and encrypt PII maintained on information systems. Similarly, the Government Accountability Office recently reported that the Department had not yet installed encryption technology to protect sensitive data on the vast majority of laptop computers and handheld devices. Because of the potential for harm, we initiated this audit to determine whether the Department and its contractors adequately safeguarded sensitive electronic information. The Department had taken a number of steps to improve protection of PII. Our review, however

    The U.S. Department of Energy (DOE) Office of Nuclear Energy (NE) recently sponsored the creation of a roadmap for instrumentation, controls, and human-machine interface (ICHMI) technology development. The roadmap represents the collective efforts of a group of subject matter experts from the DOE national laboratories, academia, vendors, the U.S. Nuclear Regulatory Commission (NRC), and utilities. It is intended to provide the underpinnings to the government sponsored ICHMI research, development, and demonstration (RD and D) performed in the United States for the next several years. A distinguishing feature of this roadmapping effort is that it is not limited to a technology progression plan but includes a detailed rationale, aimed at the nonspecialist, for the existence of a focused ICHMI RD and D program. Eight specific technology areas were identified for focused RD and D as follows: (1) sensors and electronics for harsh environments,(2) uncertainty characterization for diagnostics/prognostics applications, (3) quantification of software quality for high-integrity digital applications, (4) intelligent controls for nearly autonomous operation of advanced nuclear plants, (5) plant network architecture, (6) intelligent aiding technology for operational support, (7) human system interaction models and analysis tools, and (8) licensing and regulatory challenges and solutions.

  20. The Electronically Steerable Flash Lidar: A NASA Facility Instrument for Ecological Studies

    The Electronically Steerable Flash Lidar (ESFL) is a lidar concept created at Ball Aerospace and developed in conjunction with NASA. It represents a new paradigm for airborne or spaceborne lidar remote sensing. Instead of the mechanical scanning common to airborne lidars, or the fixed beam approach found in spaceborne lidars, ESFL allows the number and position of transmitted beams to vary shot-to-shot. This is done using an acousto-optic beam deflector that splits a single laser beam into N output beams, where N and the position of beam N on the ground can be reconfigured in real time electronically. This transmitter concept is coupled with a Flash Focal Plane Array (FFPA), a pixilated detector where every pixel delivers a time-resolved intensity waveform, thus allowing lidar imaging. The ESFL enables several jumps in capability for remote sensing of ecosystems. Multiple spatial scales can be probed simultaneously or within the same flight transect because beam spacings can be varied in real time. This means contiguous beams can be applied to regions where smaller scale variability needs to be probed, and in areas where maximum across-track coverage is needed, those beams are spread out. Furthermore, each beam can be projected onto multiple pixels, allowing one to collect a waveform over multiple length scales simultaneously. The electronic interface with the AOBD means that the transmitted pattern can respond to any of a multitude of inputs. The ESFL can interface with another forward-looking sensor, such as a hyperspectral instrument or another lidar or a digital camera. The data from that second sensor could be used to direct the ESFL observation toward, for example, an area with a specific spectral signature, or an area free from clouds. The ESFL concept was designed with a path to space in mind, but an airborne version has been built and tested on aircraft. The work continues under a NASA Airborne Instrument Technology Transition (AITT) grant designed to

    Full text: The nuclear power industry is currently facing increasing aging and obsolescence issues with original equipment installed for instrumentation, control, and safety system applications. One area that needs attention is the aging of electronic boards and components used in instrumentation and control (I and C) systems in nuclear power plants (NPPs). In this context, EPRI has launched a project dedicated to NPP electronic component and board aging management. The goals of this project are: 1) to better understand the degradation mechanisms of I and C electronic systems; 2) to develop new methods to monitor prevalent mechanisms and forecast generic aging cases; and 3) to give guidelines for the aging management of I and C electronic systems. The ultimate objectives are: 1) to reduce the likelihood of losing plant availability due to a board or component failure; and 2) to reduce the global cost of maintenance by optimizing preventive maintenance tasks and the schedule for refurbishment or renewal. Degradation mechanisms of electronic boards in NPP - Aging mechanisms of electronic parts depend on technologies, manufacturing quality, and conditions of environment and operation. Aging of electronic parts is well documented in harsh environments (e.g., aerospace, military, or automotive industries data). However, only a small amount of data on electronic part failures in NPPs is available because the conditions are benign and the failure rates are supposed to be low. It is thus difficult to identify what will predominantly cause the aging of electronic systems after 20 or 30 years of operation. Usual causes are temperature, corrosion, temperature cycles, or extrinsic aggressions (Electrical Over Stress (EOS), Electro Static Discharges (ESD)). From field data and bibliographic analyses, we found that electrolytic capacitors, relays, potentiometers, power devices (thyristors, power transistors, etc.), optocouplers, on-board connectors, printed boards, integrated

    The Magnetic Electron Ion Spectrometer (MagEIS) instruments aboard the Van Allen Probes Spacecraft (formerly RBSP) measure electrons and ions in the Earth's inner and outer radiation belts. The MagEIS instruments are part of the Energetic Particle, Composition, and Thermal Plasma Suite (ECT), which also includes the Relativistic Electron Proton Telescope (REPT) and the Helium Oxygen Proton Electron (HOPE) analyzer. MagEIS consists of four magnetic electron spectrometers aboard each of the two Van Allen Probes spacecraft that measure the differential fluxes, energies, and angular distributions of electrons from 20 keV to 4 MeV. The MagEIS suite also contains a silicon-detector telescope that measures the differential fluxes, energies, and angular distributions of protons from 60 keV to 20 MeV, and helium and oxygen ions above a hundred keV/AMU. We briefly describe the instrument design and measurement technique and present a set of results from the MagEIS observations, including ultra-low frequency (ULF) modulations of energetic electron flux, and observations of electron flux enhancements associated with the recent BARREL x-ray observations.

    Full Text Available Introduction: Cleanliness of the canal space is the ultimate goal of its preparation. Nevertheless, some portion of the canal walls are left un-instrumented during preparation. Therefore, the aim of this ex vivo study was to evaluate the cleanliness of un-instrumented canal walls after root canal preparation for the presence or absence of debris and smear layer. Materials and Methods: A total of 24 single-rooted extracted teeth were prepared with the crown-down technique using Protaper universal rotary file system. Micro-computed tomography (micro-CT was used to scan the specimens before and after instrumentation. The un-instrumented area was measured and localized. The roots were split longitudinally and then subjected to scanning electron microscopy (SEM. The presence of debris and smear layer in the instrumented and un-instrumented areas of the canal were evaluated by analysing the SEM images with a five-score evaluation system based on the reference photographs. Results: High levels of root canal cleanliness (≤ score 2 were found for the instrumented areas were detected (P = 0.003. Conclusions: Under the condition of this study, un-instrumented areas of the canal were less clean in comparison to instrumented portion.

    2017-04-01

    Full Text Available The Hugh Davies Collection (HDC at the Science Museum in London comprises 42 items of electronic sound apparatus owned by English experimental musician Hugh Davies (1943–2005, including self-built electro-acoustic musical instruments and modified sound production and manipulation hardware. An early proponent of ‘live electronic music’ (performed live on stage rather than constructed on magnetic tape in a studio, Davies’s DIY approach shaped the development of experimental and improvised musics from the late 1960s onwards. However, his practice has not been widely reported in the literature, hence little information is readily available about the material artefacts that constituted and enabled it. This article provides the first account of the development of Davies’s practice in relation to the objects in the HDC: from the modified electronic sound apparatus used in his early live electronic compositions (among the first of their kind by a British composer; through the ‘instrumental turn’ represented by his first self-built instrument, Shozyg I (1968; to his mature practice, where self-built instruments like Springboard Mk. XI (1974 replaced electronic transformation as the primary means by which Davies explored new and novel sound-worlds. As well as advancing knowledge of Davies’s pioneering work in live electronics and instrument-building and enhancing understanding of the objects in the HDC, this article shows how object biographic and archival methodologies can be combined to provide insight into the ways in which objects (instruments, technologies and practices shape each other over time.

  9. Development and implementation of an electronic interface for complex clinical laboratory instruments without a vendor-provided data transfer interface

    Directory of Open Access Journals (Sweden)

    Gary E Blank

    2011-01-01

    Full Text Available Background: Clinical pathology laboratories increasingly use complex instruments that incorporate chromatographic separation, e.g. liquid chromatography, with mass detection for rapid identification and quantification of biochemicals, biomolecules, or pharmaceuticals. Electronic data management for these instruments through interfaces with laboratory information systems (LIS is not generally available from the instrument manufacturers or LIS vendors. Unavailability of a data management interface is a limiting factor in the use of these instruments in clinical laboratories where there is a demand for high-throughput assays with turn-around times that meet patient care needs. Materials and Methods: Professional society guidelines for design and transfer of data between instruments and LIS were used in the development and implementation of the interface. File transfer protocols and support utilities were written to facilitate transfer of information between the instruments and the LIS. An interface was created for liquid chromatography-tandem mass spectroscopy and inductively coupled plasma-mass spectroscopy instruments to manage data in the Sunquest® LIS. Results: Interface validation, implementation and data transfer fidelity as well as training of technologists for use of the interface was performed by the LIS group. The technologists were familiarized with the data verification process as a part of the data management protocol. The total time for the technologists for patient/control sample data entry, assay results data transfer, and results verification was reduced from approximately 20 s per sample to <1 s per sample. Sample identification, results data entry errors, and omissions were eliminated. There was electronic record of the technologist performing the assay runs and data management. Conclusions: Development of a data management interface for complex, chromatography instruments in clinical laboratories has resulted in rapid, accurate

    To synthesize the findings of cognitive interview and usability studies performed to assess the measurement equivalence of patient-reported outcome (PRO) instruments migrated from paper to electronic formats (ePRO), and make recommendations regarding future migration validation requirements and ePRO design best practice. We synthesized findings from all cognitive interview and usability studies performed by a contract research organization between 2012 and 2015: 53 studies comprising 68 unique instruments and 101 instrument evaluations. We summarized study findings to make recommendations for best practice and future validation requirements. Five studies (9%) identified minor findings during cognitive interview that may possibly affect instrument measurement properties. All findings could be addressed by application of ePRO best practice, such as eliminating scrolling, ensuring appropriate font size, ensuring suitable thickness of visual analogue scale lines, and providing suitable instructions. Similarly, regarding solution usability, 49 of the 53 studies (92%) recommended no changes in display clarity, navigation, operation, and completion without help. Reported usability findings could be eliminated by following good product design such as the size, location, and responsiveness of navigation buttons. With the benefit of accumulating evidence, it is possible to relax the need to routinely conduct cognitive interview and usability studies when implementing minor changes during instrument migration. Application of design best practice and selecting vendor solutions with good user interface and user experience properties that have been assessed in a representative group may enable many instrument migrations to be accepted without formal validation studies by instead conducting a structured expert screen review.

    2007-10-01

    Full Text Available In this paper we present an inexpensive electronic measurement instrumentationdeveloped in our laboratory, to measure and plot the impedance of a loaded fuel cell orbattery. Impedance measurements were taken by using the load modulation method. Thisinstrumentation has been developed around a VXI system stand which controls electroniccards. Software under Hpvee® was developed for automatic measurements and the layout ofthe impedance of the fuel cell on load. The measurement environment, like the ambienttemperature, the fuel cell temperature, the level of the hydrogen, etc..., were taken withseveral sensors that enable us to control the measurement. To filter the noise and theinfluence of the 50Hz, we have implemented a synchronous detection which filters in a verynarrow way around the useful signal. The theoretical result obtained by a simulation underPspice® of the method used consolidates the choice of this method and the possibility ofobtaining correct and exploitable results. The experimental results are preliminary results ona 12V vehicle battery, having an inrush current of 330A and a capacity of 40Ah (impedancemeasurements on a fuel cell are in progress, and will be the subject of a forthcoming paper.The results were plotted at various nominal voltages of the battery (12.7V, 10V, 8V and 5Vand with two imposed currents (0.6A and 4A. The Nyquist diagram resulting from theexperimental data enable us to show an influence of the load of the battery on its internalimpedance. The similitude in the graph form and in order of magnitude of the valuesobtained (both theoretical and practical enables us to validate our electronic measurementinstrumentation. One of the future uses for this instrumentation is to integrate it with several control sensors, on a vehicle as an embedded system to monitor the degradation of fuel cell membranes.

    Background The practice of transfusing red blood cells is still liberal in some centres suggesting a lack of compliance with guidelines recommending transfusion of red blood cells at haemoglobin levels of 6–8 g/dL in the non-bleeding patient. Few databases provide ongoing feedback of data on pre-transfusion haemoglobin levels at the departmental level. In a tertiary care hospital, no such data were produced before this study. Our aim was to establish a Patient Blood Management database based on electronic data capture in order to monitor compliance with transfusion guidelines at departmental and hospital levels. Materials and methods Hospital data on admissions, diagnoses and surgical procedures were used to define the populations of patients. Data on haemoglobin measurements and red blood cell transfusions were used to calculate pre-transfusion haemoglobin, percentage of transfused patients and transfusion volumes. Results The model dataset include 33,587 admissions, of which 10% had received at least one unit of red blood cells. Haemoglobin measurements preceded 96.7% of the units transfused. The median pre-transfusion haemoglobin was 8.9 g/dL (interquartile range 8.2–9.7) at the hospital level. In only 6.5% of the cases, transfusion was initiated at 7.3 g/dL or lower as recommended by the Danish national transfusion guideline. In 27% of the cases, transfusion was initiated when the haemoglobin level was 9.3 g/dL or higher, which is not recommended. A median of two units was transfused per transfusion episode and per hospital admission. Transfusion practice was more liberal in surgical and intensive care units than in medical departments. Discussion We described pre-transfusion haemoglobin levels, transfusion rates and volumes at hospital and departmental levels, and in surgical subpopulations. Initial data revealed an extensive liberal practice and low compliance with national transfusion guidelines, and identified wards in need of intervention. PMID

    The purpose of this study was to describe a workflow analysis approach and apply it in emergency departments (EDs) using data extracted from the electronic health record (EHR) system. We used data that were obtained during 2013 from the ED of a children's hospital and its four satellite EDs. Workflow-related data were extracted for all patient visits with either a primary or secondary diagnosis on discharge of asthma (ICD-9 code=493). For each patient visit, eight different a priori time-stamped events were identified. Data were also collected on mode of arrival, patient demographics, triage score (i.e. acuity level), and primary/secondary diagnosis. Comparison groups were by acuity levels 2 and 3 with 2 being more acute than 3, arrival mode (ambulance versus walk-in), and site. Data were analyzed using a visualization method and Markov Chains. To demonstrate the viability and benefit of the approach, patient care workflows were visually and quantitatively compared. The analysis of the EHR data allowed for exploration of workflow patterns and variation across groups. Results suggest that workflow was different for different arrival modes, settings and acuity levels. EHRs can be used to explore workflow with statistical and visual analytics techniques novel to the health care setting. The results generated by the proposed approach could be utilized to help institutions identify workflow issues, plan for varied workflows and ultimately improve efficiency in caring for diverse patient groups. EHR data and novel analytic techniques in health care can expand our understanding of workflow in both large and small ED units. Copyright © 2015 Elsevier Inc. All rights reserved.

    Uncontrolled hypertension is associated with significant patient morbidity and health care costs. Many patients evaluated in the emergency department (ED) do not regularly consult health care providers and have socioeconomic barriers to receiving primary care. Hypertension screening and counseling has been advocated as a routine part of ED care. Previous work has shown poor referral rates and education for ED patients presenting with elevated blood pressure (BP). We sought to determine whether implementation of an electronic medical record (EMR) would improve these rates. We performed a retrospective study conducted in 2 urban academic EDs, comparing pre-EMR (handwritten discharge) to post-EMR discharge instructions for patient referral for BP management and education on lifestyle modification. Medical records of patients aged ≥ 18 years with a systolic BP rate ≥ 140 or diastolic BP rate ≥ 90 mm Hg were included. Patient data included demographics, BP rate, presenting symptoms, and administration of antihypertensive medication while in the ED. Discharge instructions were reviewed for a directed referral for outpatient BP management, prescriptions for antihypertensive medication, and lifestyle modifications. Of the 1000 medical records reviewed, 500 were pre- and 500 were post-EMR, including a total of 389 patients who had persistently elevated BP on reassessment. At discharge, acknowledgment of elevated BP occurred in 45% of patients in the pre-EMR phase and only 26% in the post-EMR phase (P patients and in 15% of the post-EMR patients (P patient included increasing BP rate, pharmacologic treatment of hypertension in the ED, or provision of a prescription for an antihypertensive medication at discharge. The post-EMR phase was negatively associated with a directed referral for outpatient BP management. Overall, the initiation of EMR led to a decrease in outpatient referrals and acknowledgment of elevated BP rates in discharge instructions. The provision of

    Full Text Available Sea level is one of ocean properties that needed to be observed. Sea level observation will give information about osean tides and tides datum. As technology became more reliable, people can develop new instrument easily. Recently, open source microcontroller “Arduino” became popular and lot of people using it to develop what we call “low-cost” instrument. But, there are several disadvantages if we build instrument directly. Simulation phase must be done before manufacture instrument. This phase will help to decrease cost and time. In this paper, we will describe the concept, algorithm, and simulation phase in manufacturing Low Cost Ocean Tides Monitoring Instrument.

    2014-01-01

    The LHC cryogenic system radiation tolerant electronics and their associated field instruments have been in nominal conditions since before the commissioning of the first LHC beams in September 2008. This system is made of about 15’000 field instruments (thermometers, pressure sensors, liquid helium level gauges, electrical heaters and position switches), 7’500 electronic cards and 853 electronic crates. Since mid-2008 a software tool has been deployed, this allows an operator to report a problem and then lists the corrective actions. The tool is a great help in detecting recurrent problems that may be tackled by a hardware or software consolidation. The corrective actions range from simple resets, exchange of defective equipment, repair of electrical connectors, etc. However a recurrent problem that heals by itself is present on some channels. This type of fault is extremely difficult to diagnose and it appears as a temporary opening of an electrical circuit; its duration can range from a few minutes to ...

    Prescription errors occur frequently in pediatric emergency departments (PEDs).The effect of computerized physician order entry (CPOE) with electronic medication alert system (EMAS) on these is unknown. The objective was to compare prescription errors rates before and after introduction of CPOE with EMAS in a PED. The hypothesis was that CPOE with EMAS would significantly reduce the rate and severity of prescription errors in the PED. A prospective comparison of a sample of outpatient, medication prescriptions 5 months before and after CPOE with EMAS implementation (7,268 before and 7,292 after) was performed. Error types and rates, alert types and significance, and physician response were noted. Medication errors were deemed significant if there was a potential to cause life-threatening injury, failure of therapy, or an adverse drug effect. There was a significant reduction in the errors per 100 prescriptions (10.4 before vs. 7.3 after; absolute risk reduction = 3.1, 95% confidence interval [CI] = 2.2 to 4.0). Drug dosing error rates decreased from 8 to 5.4 per 100 (absolute risk reduction = 2.6, 95% CI = 1.8 to 3.4). Alerts were generated for 29.6% of prescriptions, with 45% involving drug dose range checking. The sensitivity of CPOE with EMAS in identifying errors in prescriptions was 45.1% (95% CI = 40.8% to 49.6%), and the specificity was 57% (95% CI = 55.6% to 58.5%). Prescribers modified 20% of the dosing alerts, resulting in the error not reaching the patient. Conversely, 11% of true dosing alerts for medication errors were overridden by the prescribers: 88 (11.3%) resulted in medication errors, and 684 (88.6%) were false-positive alerts. A CPOE with EMAS was associated with a decrease in overall prescription errors in our PED. Further system refinements are required to reduce the high false-positive alert rates. © 2015 by the Society for Academic Emergency Medicine.

    A small proportion of patients account for a high proportion of healthcare use. Accurate preemptive identification may facilitate tailored intervention. We sought to determine whether machine learning techniques using text from a family practice electronic medical record can be used to predict future high emergency department use and total costs by patients who are not yet high emergency department users or high cost to the healthcare system. Text from fields of the cumulative patient profile within an electronic medical record of 43,111 patients was indexed. Separate training and validation cohorts were created. After processing, 11,905 words were used to fit a logistic regression model. The primary outcomes of interest in the 12 months after prediction were 3 or more emergency department visits and being in the top 5% in healthcare expenditures. Outcomes were assessed through linkage to administrative databases housed at the Institute for Clinical Evaluative Sciences. In the model to predict frequent emergency department visits, after excluding patients who were high emergency department users in the previous year, the area under the receiver operating characteristic curve was 0.71. By using the same methodology, the model to predict the top 5% in total system costs had an area under the receiver operating characteristic curve of 0.76. Machine learning techniques can be applied to analyze free text contained in electronic medical records. This dataset is more predictive of patients who will generate future high costs than future emergency department visits. It remains to be seen whether these predictions can be used to reduce costs by early interventions in this cohort of patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    Hospitals currently rely on simple human visual inspection for assessing cleanliness of surgical instruments. Studies showed that surgical site infections are in part attributed to inadequate cleaning of medical devices. Standards groups recognize the need to objectively quantify the amount of residues on surgical instruments and establish guidelines. We developed a portable technology for the detection of contaminants on surgical instruments through fluorescence following cleaning. Weak fluorescence signals are usually detected in the obscurity only with the lighting of the excitation source. The key element of this system is that it works in ambient lighting conditions, a requirement to not disturb the normal workflow of hospital reprocessing facilities. A biocompatible fluorescent dye is added to the detergent and labels the proteins of organic residues. It is resistant to the harsh environment in a washer-disinfector. Two inspection devices have been developed with a 488nm laser as the excitation source: a handheld scanner and a tabletop station using spectral-domain and time-domain ambient light cancellation schemes. The systems are eye safe and equipped with image processing and interfacing software to provide visual or audible warnings to the operator based on a set of adjustable signal thresholds. Micron-scale residues are detected by the system which can also evaluate soil size and mass. Unlike swabbing, it can inspect whole tools in real-time. The technology has been validated in an independent hospital decontamination research laboratory. It also has potential applications in the forensics, agro-food, and space fields. Technical aspects and results will be presented and discussed.

    Circuitry is described for testing the ability of an intermediate range nuclear instrument to detect and measure a constant current and a periodic current pulse. The invention simulates the resistance and capacitance of the signal connection of a nuclear instrument ion chamber detector and interconnecting cable. An LED flasher/oscillator illuminates an LED at a periodic rate established by a timing capacitor and circuitry internal to the flasher/oscillator. When the LED is on, a periodic current pulse is applied to the instrument. When the LED is off, a constant current is applied. An inductor opposes battery current flow when the LED is on. 1 figures.

    ED staff use a range of poisons information resources of varying type and quality. The present study aims to identify those resources utilised in the state of Victoria, Australia, and assess opinion of the most used electronic products. A previously validated self-administered survey was conducted in 15 EDs, with 10 questionnaires sent to each. The survey was then repeated following the provision of a 4-month period of access to Toxinz™, an Internet poisons information product novel to the region. The study was conducted from December 2010 to August 2011. There were 117 (78%) and 48 (32%) responses received from the first and second surveys, respectively, a 55% overall response rate. No statistically significant differences in professional group, numbers of poisoned patients seen or resource type accessed were identified between studies. The electronic resource most used in the first survey was Poisindex® (48.68%) and Toxinz™ (64.1%) in the second. There were statistically significant (P poisons information but would do so if a reputable product was available. The order of poisons information sources most utilised was: consultation with a colleague, in-house protocols and electronic resources. There was a significant difference in satisfaction with electronic poisons information resources and a movement away from existing sources when choice was provided. Interest in increased use of mobile solutions was identified. © 2014 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    The ISET (Instrument for SElf-Triage) is a validated pen-and-paper instrument for patient self-triage in ophthalmic emergency departments. The aim of the present study is to develop a validated computer-assisted ISET (ca-ISET) with a touch screen. In the emergency department of the Eye Hospital Rotterdam, the Netherlands, successive computer-assisted versions of the ISET were tested by patients visiting the emergency department. The versions were developed by iteratively prototyping, testing, analysing and refining the computer-assisted ISET. In three test cycles, 16, 53 and 75 patients ≥ 18 years old, visiting the emergency department for the first time with their ophthalmic complaint, were monitored while using the ca-ISET. They were debriefed, and their input was used to adapt the computer-assisted ISET. To validate the ca-ISET, a sensitivity outcome of .80 and a specificity of .70 was required (CI=95%). The ca-ISET sensitivity and specificity were tested by comparing ca-ISET triage outcome to triage outcome as decided by the regular triage assistant. ISET accuracy increased from 0.69 in the first test to 0.79 in the third test. Sensitivity increased from 0.66 (CI 0.13-0.98) to 0.80 (0.51-0.95). Specificity increased from 0.69 (0.39-0.90) to 0.78 (0.65-0.88). To improve validity and usability, several adjustments were made in the text and the flow chart of the computer-assisted ISET. A ca-ISET prototype was developed, with minor textual modification of the pen-and-paper version. The new ca-ISET was validated by comparing against triage decided by the regular triage assistant.

    This is the final report for the Department of Energy (DOE) funded cooperative agreement ''Electronic Research Demonstration Project (DE-FC02-92ER35180)'' for the period August 1994-July 1998. The goal of the project, referred to as NewERA, was to demonstrate the use of open standards for electronic commerce to support research administration, otherwise referred to as Electronic Research Administration (ERA). The NewERA demonstration project provided a means to test interagency standards developed within the Federal Grant Electronic Commerce Committee, a group comprised of federal granting agencies. The NewERA program was initiated by DOE. NewERA was comprised of three separate, but related, ERA activities in preaward administration, postaward administration, and secure Internet commerce. The goal of New ERA was to demonstrate an open standard implementation of ERA using electronic data interchange, e-mail and Internet transaction security between grant applicants and DOE, along with t h e other participating agencies.

  13. Overview of the relativistic electron precipitations (REP) observed on LEO satellites and ISS by Bulgarian build instruments

    Dachev, Tsvetan

    Relativistic electron precipitation (REP) are observed by the R3D B2/B3 and RD3-B3 instruments during the flights of the Foton M2/M3 and “BION-M” 1 satellite in 2005, 2007 and 2013, and by the R3DE/R instruments at the EXPOSE-E facility of the European Columbus module and at the EXPOSE-R facility of the Russian Zvezda module of the International Space Station (ISS) in the period from February 2008 till August 2010. The obtained dose rates strongly depend by the external and internal shielding of the detectors in the instruments. The highest dose rate reaching more than 20 mGy h (-1) was observed outside the ISS Zvezda module during the REP in April 2010 being the second largest in GOES history with a >2 MeV electron fluence event. REP doses behind relatively thick shielding are too small but may play considerable role during extra vehicular activity (EVA) when the cosmonauts/astronauts body is shielded only by the space suit.

    Use of electronic alerts in clinical practice has had mixed effects on providers' prescribing practices. Little research has explored the use of electronic alerts for improving screening practices. New York City has one of the highest rates of HIV in the United States. Recent New York State legislation requires healthcare providers to offer an HIV test to patients aged 13-64 years during a clinical encounter. Adhering to this requirement is particularly challenging in emergency department (ED) settings, which are frequently overcrowded and under-resourced. The purpose of this study was to evaluate the effect of an electronic "hard-stop" alert on HIV testing rates in the ED. Approximately four months of data were reviewed before and after the implementation of the alert. We found that use of the electronic alert significantly increased documentation of offering an HIV test (O.R. = 267.27, p<0.001) and resulted in a significant increase in HIV testing. Findings from this study add to the current knowledge about the use of electronic alertsfor improving disease screening.

    2014-10-16

    In January 2014, the Chicago City Council scheduled a vote on local regulation of electronic cigarettes as tobacco products. One week prior to the vote, the Chicago Department of Public Health (CDPH) released a series of messages about electronic cigarettes (e-cigarettes) through its Twitter account. Shortly after the messages, or tweets, were released, the department's Twitter account became the target of a "Twitter bomb" by Twitter users sending more than 600 tweets in one week against the proposed regulation. The purpose of our study was to examine the messages and tweet patterns in the social media response to the CDPH e-cigarette campaign. We collected all tweets mentioning the CDPH in the week between the e-cigarette campaign and the vote on the new local e-cigarette policy. We conducted a content analysis of the tweets, used descriptive statistics to examine characteristics of involved Twitter users, and used network visualization and descriptive statistics to identify Twitter users prominent in the conversation. Of the 683 tweets mentioning CDPH during the week, 609 (89.2%) were anti-policy. More than half of anti-policy tweets were about use of electronic cigarettes for cessation as a healthier alternative to combustible cigarettes (358/609, 58.8%). Just over one-third of anti-policy tweets asserted that the health department was lying or disseminating propaganda (224/609, 36.8%). Approximately 14% (96/683, 14.1%) of the tweets used an account or included elements consistent with "astroturfing"-a strategy employed to promote a false sense of consensus around an idea. Few Twitter users were from the Chicago area; Twitter users from Chicago were significantly more likely than expected to tweet in support of the policy. Our findings may assist public health organizations to anticipate, recognize, and respond to coordinated social media campaigns.

    2015-05-01

    Access to musculoskeletal consultation in the emergency department (ED) is a nationwide problem. In addition, consultation from a subspecialist may be delayed or may not be available, which can slow down the ED flow and reduce patient satisfaction. The purpose of this study was to review the 1-year results of a change in the authors' institutional practice to reduce subspecialty consultation for select musculoskeletal problems while still ensuring adequate patient follow-up in orthopedic or plastic surgery clinics for patients not seen by these services in the ED. The authors hypothesized that select injuries could be safely managed in the ED by using an electronic system to ensure appropriate follow-up care. Using Kaizen methodology, a multidisciplinary group (including ED staff, orthopedics, plastic surgery, pediatrics, nursing, radiology, therapy, and administration) met to improve care for select musculoskeletal injuries. A system was agreed on in which ED providers managed select musculoskeletal injuries without subspecialist consultation. Follow-up was organized using an electronic system, which facilitated communication between the ED staff and the secretarial staff of the subspecialist departments. Over a 1-year period, 150 patients were treated using this system. Charts and radiographs were reviewed for missed injuries. Radiographic review revealed 2 missed injuries. One patient had additional back pain and a lumbar spine fracture was found during the subspecialist follow-up visit; it was treated nonoperatively. Another patient appeared to have scapholunate widening on the injury radiograph that was not appreciated in the ED. Of the 150 patients, 51 were seen in follow-up by a subspecialist at the authors' institution. An electronic system to organize follow-up with a subspecialist allowed the ED providers to deliver safe and effective care for simple musculoskeletal injuries. Copyright 2015, SLACK Incorporated.

    To describe the experience in the development of an electronic emergency department (ED)-based injury surveillance (IS) system in Hong Kong using data-mining and geo-spatial information technology (IT) for a Safe Community setup. This paper described the phased development of an emergency department-based IS system based on World Health Organization (WHO) injury surveillance Guideline to support safety promotion and injury prevention in a Safe Community in Hong Kong starting 2002. The initial ED data-based only collected data on name, sex, age, address, eight general categories of injury types (traffic, domestic, common assault, indecent assault, batter, industrial, self-harm and sports) and disposal from ED. Phase 1--manual data collection on International Classification of External Causes of Injury pre-event data; Phase 2--manual form was converted to electronic format using web-based data mining technology with built in data quality monitoring mechanism; Phase 3--integration of injury surveillance-data with in-patient hospital information; and Phase 4--geo-spatial information and body mapping were introduced to geo-code exact place of injury in an electronic map and site of injury on body map. It was feasible to develop a geo-spatial IS system at busy ED to collect valuable information for safety promotion and injury prevention at Safe Community setting. The keys for successful development and implementation involves engagement of all stakeholders at design and implementation of the system with injury prevention as ultimate goal, detail workflow planning at front end, support from the management, building on exiting system and appropriate utilisation of modern technology.

    In the scope of the evaluation of architecture and technologies for the control system of the E-ELT (European-Extremely Large Telescope) instruments, a collaboration has been set up between the Instrumentation and Control Group of the INAF-OATs and the ESO Directorate of Engineering. The first result of this collaboration is the design and implementation of a prototype of a small but representative control system for a kind of multi-object (optical) spectrograph. The electronics has been based on PLCs (Programmable Logical Controller) and Ethernet based field-buses from different vendors but using international standards like the IEC 61131-3 and PLCopen Motion Control. The baseline design for the control software follows the architecture of the VLT (Very Large Telescope) Instrumentation application framework but it has been implemented using the ACS (ALMA Common Software), an open source software framework developed for the ALMA project and based on CORBA middle-ware. The communication among the software components is based on two models: CORBA calls for command/reply using the client/server paradigm and CORBA notification channel for distributing the devices status using the publisher/subscriber paradigm. The communication with the PLCs is based on OPC UA, an international standard for the communication with industrial controllers. The results of this work will contribute to the definition of the architecture of the control system that will be provided to all consortia responsible for the actual implementation of the E-ELT instruments. This paper presents the prototype motivation, its architecture, design and implementation. (authors)

    1996-01-01

    The Laboratory Virtual Instrumentation Engineering Workstation (LabVIEW) software is designed such that equipment and processes related to control systems can be operationally lined and controlled by the use of a computer. Various processes within the failure analysis laboratories of NASA's Kennedy Space Center (KSC) demonstrate the need for modernization and, in some cases, automation, using LabVIEW. An examination of procedures and practices with the Failure Analaysis Laboratory resulted in the conclusion that some device was necessary to elevate the potential users of LabVIEW to an operational level in minimum time. This paper outlines the process involved in creating a tutorial application to enable personnel to apply LabVIEW to their specific projects. Suggestions for furthering the extent to which LabVIEW is used are provided in the areas of data acquisition and process control.

    Electrical discharges in accelerating structures are one of the key issues limiting the performance of future high energy accelerators such as the Compact Linear Collider (CLIC). Fundamental understanding of breakdown phenomena is an indispensable part of the CLIC feasibility study. The present work concerns the experimental study of breakdown using Scanning Electron Microscopes (SEMs). A SEM gives us the opportunity to achieve high electrical gradients of 1\\,kV/$\\mu$m which corresponds to 1\\,GV/m by exciting a probe needle with a high voltage power supply and controlling the positioning of the needle with a linear piezo motor. The gap between the needle tip and the surface is controlled with sub-micron precision. A second electron microscope equipped with a Focused Ion Beam (FIB) is used to create surface corrugations and to sharpen the probe needle to a tip radius of about 50\\,nm. Moreover it is used to prepare cross sections of a voltage breakdown area in order to study the geometrical surface damages as w...

    JPL has developed high performance cold cathodes using arrays of carbon nanotube bundles that produce > 15 A/sq cm at applied fields of 5 to 8 V/micron without any beam focusing. They have exhibited robust operation in poor vacuums of 10(exp -6) to 10(exp -4) Torr- a typically achievable range inside hermetically sealed microcavities. Using these CNT cathodes JPL has developed miniature X-ray tubes capable of delivering sufficient photon flux at acceleration voltages of <20kV to perform definitive mineralogy on planetary surfaces; mass ionizers that offer two orders of magnitude power savings, and S/N ratio better by a factor of five over conventional ionizers. JPL has also developed a new class of programmable logic gates using CNT vacuum electronics potentially for Venus in situ missions and defense applications. These digital vacuum electronic devices are inherently high-temperature tolerant and radiation insensitive. Device design, fabrication and DC switching operation at temperatures up to 700 C are presented in this paper.

    The purpose of this study was to understand the factors which promoted the demand for iPads by physicians in two Emergency departments (ED) prior to a system wide implementation of an electronic medical record (EMR). A grounded theory design was employed and 14 semi-structured interviews conducted with ED physicians. Analysis of the interview transcripts was completed using Atlas.ti qualitative software, which revealed that physicians' perceptions of iPad use in the ED stemmed from their personal use of iPads along with three perceived ease of use factors. Physicians perceived that improved patient physician interaction, improved workflow and structural iPad benefits promoted their demand. Physicians perceived the structural benefits of iPads would improve patient physician interaction and improve workflow in the ED. As interest in handheld devices such as iPads increases, these findings could direct and encourage other iPad implementations at other hospital EDs'.

    Repeated sterilizations cycles cause undesirable alterations in the material properties of the instruments, such as corrosion, alterations in the hardness of the metal and the loss of the cutting sharpness of the instrument. This research examined the effect of repeated dry heat sterilization and autoclaves cycles on carbon steel (CS) and stainless steel (SS) curettes during the scaling and root planning. A total of 77 Gracey curettes were used in this study. Of these, 35 were SS and 42 were CS curettes submitted in different process: Dry heat, autoclave, inhibition of corrosion and autoclave, scaling, root planning and dry heat, scaling, root planning, inhibition of corrosion and autoclave. The inhibition of corrosion used on the carbon curettes (prior to sterilization in the autoclave) was sodium nitrite at 2%. The curettes received 10 consecutive cycles of sterilization and after that the cutting edges were examined in the electronic microscope, at 60 and 100 magnification times. The images were evaluated by three independent examiners, who compared the photographs of each group with the control group. The surface corrosion products and a deterioration of the edges were observed and the results showed that the SS curettes suffered little alteration with sterilization, scaling, root planning whereas the CS curettes were visibly affected by sterilization in the autoclave, but when the inhibition of corrosion was used prior to the sterilization, the oxidation was considerably reduced.

    Voronov, S.; Pamela Collaboration

    The main goal of the magnetic spectrometer PAMELA is the study of antiparticle fluxes with energy up to 300 GeV in cosmic rays on board satellite. A modification of instrument was done by introducing of neutron detector. This device was placed under imaging calorimeter and bottom scintillator counter. It consists of two layers of 36 3He gas counters enveloped by a polyethylene moderator. The neutron detector gives additional possibility to identify the antiprotons going in aperture of spectrome- ter and generating the nuclear cascade in tungsten plates of calorimeter. This shower is followed by big number of neutrons in contrast to electromagnetic one caused by elec- tron or positron. From other side the combination of the imaging calorimeter, bottom scintillator and neutron detector constitute the independent instrument with large field of view which gives the possibility to measure the electron-positron cosmic ray com- ponent in energy range 1011-1013 eV with a rejection factor of order 10-4 regarding to nuclear one.

    The Advanced eLectron-PHoton fAcility (ALPHA) is a compact electron accelerator under construction and being commissioned at the Indiana University Center for Exploration of Energy and Matter (CEEM). In this thesis, we have studied the refurbished Cooler Injector Synchrotron (CIS) RF cavity using both the transmission line model and SUPERFISH simulation. Both low power and high power RF measurements have been carried out to characterize the cavity. Considering the performance limit of ferrite, we have designed a new ferrite loaded, co-axial quarter wave like cavity with similar structure but a more suitable ferrite material. We have also designed a traveling wave stripline kicker for fast extraction by POISSON and Microwave Studio. The strips geometry is trimmed to maximize the uniformity of the kicking field and match the impedance of the power cables. The time response simulation shows the kicker is fast enough for machine operation. The pulsed power supply requirement has also been specified. For the beam diagnosis in the longitudinal direction, we use a wideband Wall Gap Monitor (WGM) served in CIS. With proper shielding and amplification to get good WGM signal, we have characterized the injected and extracted beam signal in single pass commissioning, and also verified the debunching effect of the ALPHA storage ring. A modulation-demodulation signal processing method is developed to measure the current and longitudinal profile of injected beam. By scanning the dipole strength in the injection line, we have reconstructed the tomography of the longitudinal phase space of the LINAC beam. In the accumulation mode, ALPHA will be operated under a low energy and high current condition, where intra beam scattering (IBS) becomes a dominant effect on the beam emittance. A self consistent simulation, including IBS effect, gas scattering and linear coupling, has been carried out to calculate the emittance of the stored beam.

    Rigorous evaluation of an intervention requires that its allocation be unbiased with respect to confounders; this is especially difficult in complex, system-wide healthcare interventions. We developed a short survey instrument to identify factors for a minimization algorithm for the allocation of a hospital-level intervention to reduce emergency department (ED) waiting times in Ontario, Canada. Potential confounders influencing the intervention's success were identified by literature review, and grouped by healthcare setting specific change stages. An international multi-disciplinary (clinical, administrative, decision maker, management) panel evaluated these factors in a two-stage modified-delphi and nominal group process based on four domains: change readiness, evidence base, face validity, and clarity of definition. An original set of 33 factors were identified from the literature. The panel reduced the list to 12 in the first round survey. In the second survey, experts scored each factor according to the four domains; summary scores and consensus discussion resulted in the final selection and measurement of four hospital-level factors to be used in the minimization algorithm: improved patient flow as a hospital's leadership priority; physicians' receptiveness to organizational change; efficiency of bed management; and physician incentives supporting the change goal. We developed a simple tool designed to gather data from senior hospital administrators on factors likely to affect the success of a hospital patient flow improvement intervention. A minimization algorithm will ensure balanced allocation of the intervention with respect to these factors in study hospitals.

    Sepsis is a potentially life-threatening condition that requires urgent management in an Emergency Department (ED). Evidence-based guidelines for managing sepsis have been developed; however, their integration into routine practice is often incomplete. Care maps may help clinicians meet guideline targets more often. To determine if electronic clinical practice guidelines (eCPGs) improve management of patients with severe sepsis and septic shock (SS/SS). The impact of an eCPG on the management of patients presenting with SS/SS over a 3-year period at a tertiary care ED was evaluated using retrospective case-control design and chart review methods. Cases and controls, matched by age and sex, were chosen from an electronic database using physician sepsis diagnoses. Data were compared using McNemar tests or paired t-tests, as appropriate. Overall, 51 cases and controls were evaluated; the average age was 62 years, and 60% were male. eCPG patients were more likely to have a central venous pressure and central venous oxygen saturation measured; however, lactate measurement, blood cultures, and other investigations were similarly ordered (all p > 0.05). The administration of antibiotics within 3 h (63% vs. 41%; p = 0.03) and vasopressors (45% vs. 20%; p = 0.02) was more common in the eCPG group; however, use of corticosteroids and other interventions did not differ between the groups. Overall, survival was high and similar between groups. A sepsis eCPG experienced variable use; however, physicians using the eCPG achieved more quality-of-care targets for SS/SS. Strategies to increase the utilization of eCPGs in Emergency Medicine seem warranted. Copyright © 2013 Elsevier Inc. All rights reserved.

    Electronic health records (EHR) are introduced into healthcare organizations worldwide to improve patient safety, healthcare quality and efficiency. A rigorous evaluation of this technology is important to reduce potential negative effects on patient and staff, to provide decision makers with accurate information for system improvement and to ensure return on investment. Therefore, this study develops a theoretical model and questionnaire survey instrument to assess the success of organizational EHR in routine use from the viewpoint of nursing staff in residential aged care homes. The proposed research model incorporates six variables in the reformulated DeLone and McLean information systems success model: system quality, information quality, service quality, use, user satisfaction and net benefits. Two variables training and self-efficacy were also incorporated into the model. A questionnaire survey instrument was designed to measure the eight variables in the model. After a pilot test, the measurement scale was used to collect data from 243 nursing staff members in 10 residential aged care homes belonging to three management groups in Australia. Partial least squares path modeling was conducted to validate the model. The validated EHR systems success model predicts the impact of the four antecedent variables—training, self-efficacy, system quality and information quality—on the net benefits, the indicator of EHR systems success, through the intermittent variables use and user satisfaction. A 24-item measurement scale was developed to quantitatively evaluate the performance of an EHR system. The parsimonious EHR systems success model and the measurement scale can be used to benchmark EHR systems success across organizations and units and over time. PMID:29315323

    The adoption of electronic medical records (EMR) is expected to better improve overall healthcare quality and to offset the financial pressure of excessive administrative burden. However, safeguarding EMR against potentially hostile security breaches from both inside and outside healthcare facilities has created increased patients' privacy concerns from all sides. The aim of our study was to examine the influencing factors of privacy protection for EMR by healthcare professionals. We used survey methodology to collect questionnaire responses from staff members in health information management departments among nine Taiwanese hospitals active in EMR utilisation. A total of 209 valid responses were collected in 2014. We used partial least squares for analysing the collected data. Perceived benefits, perceived barriers, self-efficacy and cues to action were found to have a significant association with intention to protect EMR privacy, while perceived susceptibility and perceived severity were not. Based on the findings obtained, we suggest that hospitals should provide continuous ethics awareness training to relevant staff and design more effective strategies for improving the protection of EMR privacy in their charge. Further practical and research implications are also discussed.

    Electronic medical records are becoming an integral part of healthcare delivery. The goal of this study was to compare paper documentation versus electronic medical record for non-traumatic chest pain to determine differences in time for physicians to complete medical records using paper versus electronic mediums. We also assessed physician satisfaction with the electronic format. We conducted this before-after study in a single large tertiary care academic emergency department. In the 'Before Period', stopwatches determined the time for paper medical recording. In the 'After Period', a template-based electronic medical record was introduced and the time for electronic recording was measured. The time to record in the before and after periods were compared using a two-sided t test. We surveyed physicians to assess satisfaction. We enrolled 100 non-traumatic patients with chest pain in the before period and 73 in the after period. The documentation time was longer using electronic charting, (9.6±5.9 min vs 6.1±2.5 min; pelectronic patient recording for non-traumatic chest pain. This is the first study that we are aware of which compared paper versus electronic medical records in the emergency department. Electronic recording took longer than paper records. Physicians were not satisfied using this electronic record. Given the time pressures on emergency physicians, a solution to minimise the charting time using electronic medical records must be found before widespread uptake of electronic charting will be possible.

  4. Instrumental fundamental parameters and selected applications of the microfocus X-ray fluorescence analysis at a scanning electron microscope

    2012-01-01

    For a decade X-ray sources have been commercially available for the microfocus X-ray fluorescence analysis (μ-XRF) and offer the possibility of extending the analytics at a scanning electron microscope (SEM) with an attached energy dispersive X-ray spectrometer (EDS). By using the μ-XRF it is possible to determine the content of chemical elements in a microscopic sample volume in a quantitative, reference-free and non-destructive way. For the reference-free quantification with the XRF the Sherman equation is referred to. This equation deduces the intensity of the detected X-ray intensity of a fluorescence peak to the content of the element in the sample by means of fundamental parameters. The instrumental fundamental parameters of the μ-XRF at a SEM/EDS system are the excitation spectrum consisting of X-ray tube spectrum and the transmission of the X-ray optics, the geometry and the spectrometer efficiency. Based on a calibrated instrumentation the objectives of this work are the development of procedures for the characterization of all instrumental fundamental parameters as well as the evaluation and reduction of their measurement uncertainties: The algorithms known from the literature for the calculation of X-ray tube spectrum are evaluated with regard to their deviations in the spectral distribution. Within this work a novel semi-empirical model is improved with respect to its uncertainties and enhanced in the low energy range as well as extended for another three anodes. The emitted X-ray tube spectrum is calculated from the detected one, which is measured at an especially developed setup for the direct measurement of X-ray tube spectra. This emitted X-ray tube spectrum is compared to the one calculated on base of the model of this work. A procedure for the determination of the most important parameters of an X-ray semi-lens in parallelizing mode is developed. The temporal stability of the transmission of X-ray full lenses, which have been in regular use at

    Among children with epilepsy, to develop and evaluate a model to predict emergency department (ED) use, an indicator of poor disease control and/or poor access to care. We used electronic health record data from 2013 to predict ED use in 2014 at 2 centers, benchmarking predictive performance against machine learning algorithms. We evaluated algorithms by calculating the expected yearly ED visits among the 5% highest risk individuals. We estimated the breakeven cost per patient per year for an intervention that reduced ED visits by 10%. We estimated uncertainty via cross-validation and bootstrapping. Bivariate analyses showed multiple potential predictors of ED use (demographics, social determinants of health, comorbidities, insurance, disease severity, and prior health care utilization). A 3-variable model (prior ED use, insurance, number of antiepileptic drugs [AEDs]) performed as well as the best machine learning algorithm at one center (N = 2730; ED visits among top 5% highest risk, 3-variable model, mean = 2.9, interquartile range [IQR] = 2.7-3.1 vs Random Forest, mean = 2.9, IQR = 2.7-3.1), and superior at the second (N = 784; mean = 2.5, IQR = 2.2-2.9 vs mean = 1.9, IQR = 1.6-2.5). The per-patient-per-year breakeven point using this model to identify high-risk individuals was $958 (95% confidence interval [CI] = $568-$1390) at one center and $1086 (95% CI = $886-$1320) at the second. Prior ED use, insurance status, and number of AEDs, taken together, predict future ED use for children with epilepsy. Our estimates suggest a program targeting high-risk children with epilepsy that reduced ED visits by 10% could spend approximately $1000 per patient per year and break even. Further work is indicated to develop and evaluate such programs. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

    The objective of this study was to develop a consensus among emergency medicine (EM) specialists working in Ireland for emergency department (ED) key performance indicators (KPIs). The method employed was a three-round electronic modified-Delphi process. An online questionnaire with 54 potential KPIs was set up for round 1 of the Delphi process. The Delphi panel consisted of all registered EM specialists in Ireland. Each indicator on the questionnaire was rated using a five-point Likert-type rating scale. Agreement was defined as at least 70% of the responders rating an indicator as 'agree' or 'strongly agree' on the rating scale. Data were analysed using standard descriptive statistics. Data were also analysed as the mean of the Likert rating with 95% confidence intervals (95% CIs). Sensitivity of the ratings was examined for robustness by bootstrapping the original sample. Statistical analyses were carried out using SPSS version 16.0. The response rates in rounds 1, 2 and 3 were 86, 88 and 88%, respectively. Ninety-seven potential indicators reached agreement after the three rounds. In the context of the Donabedian structure-process-outcome framework of performance indicators, 41 (42%) of the agreed indicators were structure indicators, 52 (54%) were process indicators and four (4%) were outcome indicators. Overall, the top-three highest rated indicators were: presence of a dedicated ED clinical information system (4.7; 95% CI 4.6-4.9), ED compliance with minimum design standards (4.7; 95% CI 4.5-4.8) and time from ED arrival to first ECG in suspected cardiac chest pain (4.7; 95% CI 4.5-4.9). The top-three highest rated indicators specific to clinical care of children in EDs were: time to administration of antibiotics in children with suspected bacterial meningitis (4.6; 95% CI 4.5-4.8), separate area available within EDs (seeing both adults and children) to assess children (4.4; 95% CI 4.2-4.6) and time to administration of analgesia in children with forearm

    With the aim of investigating the moving of the power plant Peruca dam body, measurements with the classical precise theodolite WILD T3 as well as the modern electronic instruments, KERN E2 and WILD T2000S, were carried out in order to choose the most suitable instrumentaria. All three instruments were used in measuring with the same number of horizontal angle rounds; by using the statistical tests, a significant accuracy dependency on the used instrument type was established. The most accurate results were obtained by electronic theodolite Wild T2000S (estimated variance factor {sigma}=0.61), then by KERN E2 {sigma}=1.23, and finally by T3 {sigma}=1.68. Likewise, the use of the deformation analysis, i.e. global and local tests, the highest number of significant movements was established by measuring with the WILD T2000S electronic theodolite. The interior accuracy of straight line measurement of the electronic theodolite E2 was investigated in dependence with the number of horizontal angle rounds. Unfortunately, the war in this country is the reason that the planned measurements with the GPS devices have so far not been carried out. (orig.)

    Full Text Available Aim: The aim of this study was to compare root surface characteristics following root planing with various hand- and power-driven instruments. Materials and Methods: A total of 20 single, rooted teeth were used in this study; two specimens were used as control (no instrumentation done and the remaining 18 specimens were equally divided into three groups. Specimens from each group were then subjected to root planing by one of the following instruments: (1 a Gracey curette, (2 ultrasonic tip and (3 a Rotary bur. In each case, the time required for scaling and root planing and surface roughness using the Roughness and Loss of Tooth Substance Index (RLTSI was measured. Result: The mean RLTSI scores for the Gracey curette, ultrasonic and rotary instrument groups were 2.5, 2.0 and 0.667, respectively. The mean scores of time spent for scaling and root planing by the Gracey curette, ultrasonic and rotary instrument groups in seconds were 42.50, 35.83 and 54.50, respectively. Conclusions: All the three instruments, namely Gracey curette, ultrasonic tip and rotary bur, were effective in mechanical debridement of the root surface. The results favored the use of rotary instruments for root planing to achieve a smooth, clean root surface; however, the use of rotary instrument was more time consuming, which might limit its use in clinical practice.

    Several designs have been built and operated of microwave cyclotron autoresonance accelerators (CARA's) with electron beam parameters suitable for remediation of pollutants in flue gas emissions from coal-burning power plants. CARA designs have also been developed with a TW-level 10.6 micron laser driver for electron acceleration from 50 to 100 MeV, and with UHF drivers for proton acceleration to over 500 MeV. Dose requirements for reducing SO2, NOx, and particulates in flue gas emissions to acceptable levels have been surveyed, and used to optimize the design of an electron beam source to deliver this dose.

    Little is known about the transient and sustained operational effects of electronic health records on emergency department (ED) performance. We quantify how the implementation of a comprehensive electronic health record was associated with metrics of operational performance, test ordering, and medication administration at a single-center ED. We performed a longitudinal analysis of electronic data from a single, suburban, academic ED during 28 weeks between May 2011 and November 2011. We assessed length of stay, use of diagnostic testing, medication administration, radiologic imaging, and patient satisfaction during a 4-week baseline measurement period and then tracked changes in these variables during the 24 weeks after implementation of the electronic health record. Median length of stay increased and patient satisfaction was reduced transiently, returning to baseline after 4 to 8 weeks. Rates of laboratory testing, medication administration, overall radiologic imaging, radiographs, computed tomography scans, and ECG ordering all showed sustained increases throughout the 24 weeks after electronic health record implementation. Electronic health record implementation in this single-center study was associated with both transient and sustained changes in metrics of ED performance, as well as laboratory and medication ordering. Understanding ways in which an ED can be affected by electronic health record implementation is critical to providing insight about ways to mitigate transient disruption and to maximize potential benefits of the technology.

    Solar Dynamics Observatory (SDO) is imaging the Sun in many wavelengths near simultaneously and with a resolution ten times higher than the average high-definition television. In this paper we describe our innovative systems approach to the design of the CCD cameras for two of SDO's remote sensing instruments, the Atmospheric Imaging Assembly (AIA) and the Helioseismic and Magnetic Imager (HMI). Both instruments share use of a custom-designed 16 million pixel science-grade CCD and common camera readout electronics. A prime requirement was for the CCD to operate with significantly lower drive voltages than before, motivated by our wish to simplify the design of the camera readout electronics. Here, the challenge lies in the design of circuitry to drive the CCD's highly capacitive electrodes and to digitize its analogue video output signal with low noise and to high precision. The challenge is greatly exacerbated when forced to work with only fully space-qualified, radiation-tolerant components. We describe our systems approach to the design of the AIA and HMI CCD and camera electronics, and the engineering solutions that enabled us to comply with both mission and instrument science requirements.

    In this experimental study, the amount of smear layer (SL) remnants in curved root canals after chemomechanical instrumentation with two engine-driven systems or hand instrumentation was evaluated. Forty-eight mesiobuccal roots of mandibular first molars with curvatures ranging between 25 and 35 degrees (according to Schneider's method) were divided into three groups (n=16) which were prepared by either the ProTaper Universal file series, Reciproc single file system or hand instrumentation. The canals were intermittently irrigated with 5.25% NaOCl and 17% (ethylenediaminetetraacetic acid) EDTA, followed by distilled water as the final rinse. The roots were split longitudinally and the apical third of the specimens were evaluated under 2500× magnification with a scanning electron microscope (SEM). The mean scores of the SL were calculated and analyzed using the non-parametric Kruskal-Wallis and Mann-Whitney U tests. The mean scores of the SL were 2.00±0.73, 1.94±0.68 and 1.44±0.63 µm for the ProTaper Universal, Reciproc and hand instrumentation, respectively. Mean score of SL was significantly less in the hand instrumentation group than the ProTaper (P=0.027) and Reciproc (P=0.035) groups. The difference between the two engine-driven systems, however, was not significant (P=0.803). The amount of smear layer in the apical third of curved root canals prepared with both engine-driven systems was similar and greater than the hand instrumentation technique. Complete cleanliness was not attained.

    For over 15 years, the Cluster mission passes through Earth's radiation belts at least once every two days for several hours, measuring the energetic electron intensity at energies from 30 to 400 keV. This vast amount of data has previously been considered as rather useless due to contamination by penetrating energetic particles (protons at >100 keV and electrons at >400 keV). In this study, we assess the efficiency with which aluminium shielding of RAPID/IES detector filters out contaminating high-energy electrons and protons. We base our estimation on the analysis of experimental data and a radiation transport code (Geant4). In our simulations, we use the incident particle energy distribution of the AE9/AP9 radiation belt models. We identify the Roederer L-values and energy channels that should be used with caution and show examples of misinterpreting the data, particularly in the slot region. Comparison of the data with electron and proton observations from RBSP/MagEis indicates that the subtraction from the IES electron data of proton intensities at energies 230-630 keV cleans well the data from the proton contamination. We show that the data from this detector measured in the radiation belts is still useful for many scientific applications. This is very valuable as it provides one of the longest available radiation belt data sets.

    The present investigation is concerned with the suitability of the virtual phase CCD imager for frontside detection of electrons up to 25 keV. The investigation has the objective to determine if the imager can be used in the frontside mode with a photocathode to detect very low light levels in astronomical applications, the ultimate goal being individual photon detection. It is found that the standard virtual phase imager will function properly over an extended period at low levels of 20 kV electron irradiation consistent with photon counting applications. The imager can detect individual primary electrons with nearly 100 percent efficiency. However, further studies are needed to determine the mechanisms for the flat band shifts so that the imager design may be modified to eliminate or at least reduce them.

    Properties and application of the imaging plate (IP) in transmission electron microscopy (TEM) are reviewed. TEM has the resolution level of around 0.2 nm, which enables direct observation of molecules and atoms. In TEM, there are such recording systems as photographic film, TV camera, slow-scan CCD camera and IP. IP, to the electron beam, has the higher sensitivity than the film and has the broad dynamic range. Linearity between the input beam intensity and output signal is good, which makes it possible to record the image even with the small electron dose. Signal/noise ratio and detective quantum efficiency are important factors for precise image analysis. Fading phenomenon is a defect of IP, which weakens the signal output as time passing. For instance of application, IP is used for imaging of AgBr crystal fragile to strong electron beam required for the film. IP is necessary for quantitative analysis of TEM images and for the recently developed energy-filter TEM. (K.H.)

    The computer-assisted version of a self-triage tool (ca-ISET) for an ophthalmic emergency department (ED) was developed to increase the validity of the triage procedure when trained ED staff is absent. We tested whether sensitivity, specificity, Negative Predictive Value (NPV) and Positive Predictive Value (PPV) of the ca-ISET deviated from regular triage. Patients ≥18 years visiting the ED of the Rotterdam Eye Hospital in the Netherlands were invited to participate in this prospective study. This ED focuses on eye-related problems. Patient recruitment was carried out during working hours. The ca-ISET is a touch operated software application and the algorithm of the triage is based in the Manchester triage system. For all participants three triage scores were determined by (1) the participant using the ca-ISET; (2) triage by a regular, trained triage assistant and (3) triage by one physician who was specially trained in ophthalmic triage. The diagnosis of the physician was chosen as the reference standard to define criterion validity. The order of triage administration was alternated per patient. Only cases with triage scores from the two triage systems and the reference standard were included. The outcome variables, four triage colours, were transformed into a binary score: high urgent and low urgent. The difference between the ca-ISET and regular triage in terms of sensitivity, specificity, NPV and PPV was tested by Z-scores. Of 247 eligible patients, data was elicited from 189 patients (average age 54 years, range 18-89). The sensitivity of the ca-ISET (0.89, CI: 0.75-0.96) did not differ from the sensitivity of the regular triage (0.69, CI: 0.53-0.82, Z=1.74, p=0.08). The ca-ISET was less specific (0.78, CI: 0.71-0.84) than the regular triage (0.92, CI=0.86-0.95, Z=3.04, p=0.00). We found no significant difference between the ca-ISET and regular triage for PPV (Z=0.19, p=0.85) and NPV (Z=0.03, p=0.98). The sensitivity, PPV and NPV of the ca-ISET does not

    Measurement and control of characteristics of NDT equipment and system that produce output to be interpreted by inspector is one of the most important tools for NDT reliability. Control activity should be based on: initial accurate measurement and calibration; periodical check to assure maintenance of calibration status; and, immediate verification and corrective action when any malfunctioning is suspected. 'Self-calibration' intended as capability of NDT facility to calibrate and control its own equipment and systems is very important for continuous and reliable activity. Typical approach based on this philosophy is ASTM E317 'Standard Practice for Evaluating Performance Characteristics of Ultrasonic Pulse-Echo Examination Instruments and Systems Without the Use of Electronic Measurement Instruments' that is applicable to shop or field conditions. Is 'Self-calibration' applicable to radiographic system too? Many characteristics can be self-determined according to existing practices and methods, but other ones require assistance and cooperation of supplier both for film system and x-ray equipment. A certified film system being controlled by pre-exposed filmstrips can be adopted as 'measurement device' for X-ray output concerning both intensity and contrast. Basically x-ray equipment manufacturer performs initial accurate measurement and calibration using electronic measurement and/or special instrumentation as necessary. Then specific film set on 'low-price' blocks and specimens is produced according to standard practice whose guidelines are supplied by this paper. Film set, blocks, specimens and results referred to specific film system will be the reference kit for periodical check in NDT facility. This paper supplies some guidelines for standard practice based on testing using mainly GE Inspection Technologies radiographic system being available in Avio facilities. (author)

    The present study examined 1) the accuracy of two self-report measures for detecting panic-related anxiety in emergency department (ED) patients with cardiopulmonary complaints; and 2) whether modified scoring resulted in improved performance. English-speaking adults presenting to the ED of a large public hospital with palpitations, chest pain, dizziness, or difficulty breathing were evaluated for the presence of panic-related anxiety with the Structured Clinical Interview for DSM-IV (SCID) over a one-year period. Patients completed the panic disorder modules of the Patient Health Questionnaire (PHQ-PD) and Psychiatric Diagnostic Screening Questionnaire (PDSQ-PD). Sensitivity, specificity, area under the curve (AUC), and predictive values were compared for various cut-offs and scoring algorithms using SCID diagnosis of panic attacks (in the absence of panic disorder) or panic disorder as the reference standard. In this sample of 200 participants, the majority had a chief complaint of chest pain and 46.5% met SCID criteria for panic-related anxiety. The PDSQ-PD demonstrated only fair operating characteristics for panic attacks (AUC = 0.57) and good operating characteristics for panic disorder (AUC = 0.79). The PHQ-PD achieved adequate operating characteristics (AUC = 0.66) for panic attacks and good operating characteristics for panic disorder (AUC = 0.76) using a modified scoring algorithm or a single screening question (AUC = 0.72).

    Full Text Available Background and Objectives: Scaling and root planing is one of the most commonly used procedures for the treatment of periodontal diseases. Removal of calculus using conventional hand instruments is incomplete and rather time consuming. In search of more efficient and less difficult instrumentation, investigators have proposed lasers as an alternative or as adjuncts to scaling and root planing. Hence, the purpose of the present study was to evaluate the effectiveness of erbium doped: Yttirum aluminum garnet (Er:YAG laser scaling and root planing alone or as an adjunct to hand and ultrasonic instrumentation. Subjects and Methods: A total of 75 freshly extracted periodontally involved single rooted teeth were collected. Teeth were randomly divided into five treatment groups having 15 teeth each: Hand scaling only, ultrasonic scaling only, Er:YAG laser scaling only, hand scaling + Er:YAG laser scaling and ultrasonic scaling + Er:YAG laser scaling. Specimens were subjected to scanning electron microscopy and photographs were evaluated by three examiners who were blinded to the study. Parameters included were remaining calculus index, loss of tooth substance index, roughness loss of tooth substance index, presence or absence of smear layer, thermal damage and any other morphological damage. Results: Er:YAG laser treated specimens showed similar effectiveness in calculus removal to the other test groups whereas tooth substance loss and tooth surface roughness was more on comparison with other groups. Ultrasonic treated specimens showed better results as compared to other groups with different parameters. However, smear layer presence was seen more with hand and ultrasonic groups. Very few laser treated specimens showed thermal damage and morphological change. Interpretation and Conclusion: In our study, ultrasonic scaling specimen have shown root surface clean and practically unaltered. On the other hand, hand instrument have produced a plane surface

    We implemented an electronic event-reporting system to investigate its effect on quality improvement in our department. We developed an event-reporting program that launched in October 2012; data analysis was performed in January 2014. Events were logged by the radiation oncology staff and reviewed by our quality and safety committee on a biweekly basis. To measure the efficacy of the new program, and change in safety culture, a Likert-scale survey was administered before, and three months after, implementation of the event-reporting system. A total of 194 events were logged into the new system during a 15-month period (approximately 13 events per month), compared with 93 events in an 18-month period (approximately five events per month) before the program was launched. The average number of events reported by radiation therapists increased from 0.9 per month to 8.6 per month. The survey results showed a shift toward stronger agreement by staff members, in postimplementation versus preimplementation responses, when they were asked if they knew how to report an event in the department (P = .042), and if the current event-reporting system would reduce the incidence of future events (P = .032). Results showed a trend toward stronger agreement by staff members when they were asked if they felt more comfortable reporting events that they had observed (P = .093). Multiple safety action plans were implemented as a result of analysis of these events. An electronic event-reporting system streamlines quality and safety in a radiation oncology department by increasing reported events and promoting a safety culture. A program that is widely accessible, easy to use, and can analyze data meaningfully will be the most successful. Copyright © 2015 American College of Radiology. Published by Elsevier Inc.

    Medical student evaluations are essential for determining clerkship grades. Electronic evaluations have various advantages compared to paper evaluations, such as increased ease of collection, asynchronous reporting, and decreased likelihood of becoming lost. To determine whether electronic medical student evaluations (EMSEs) provide more evaluations and content when compared to paper shift card evaluations. This before and after cohort study was conducted over a 2.5-year period at an academic hospital affiliated with a medical school and emergency medicine residency program. EMSEs replaced the paper shift evaluations that had previously been used halfway through the study period. A random sample of the free text comments on both paper and EMSEs were blindly judged by medical student clerkship directors for their helpfulness and usefulness. Logistic regression was used to test for any relationship between quality and quantity of words. A total of 135 paper evaluations for 30 students and then 570 EMSEs for 62 students were collected. An average of 4.8 (standard deviation [SD] 3.2) evaluations were completed per student using the paper version compared to 9.0 (SD 3.8) evaluations completed per student electronically (p integrated into the emergency department tracking system significantly increased the number of evaluations completed compared to paper evaluations. In addition, the EMSEs captured more "helpful/useful" information about the individual students as evidenced by the longer free text entries per evaluation. Copyright © 2016 Elsevier Inc.

    1984-09-01

    Many radiological surveillance instruments are in use at DOE facilities throughout the country. These instruments are an essential part of all health physics programs, and poor instrument performance can increase program costs or compromise program effectiveness. Generic data from simple tests on newly purchased instruments shows that many instruments will not meet requirements due to manufacturing defects. In other cases, lack of consideration of instrument use has resulted in poor acceptance of instruments and poor reliability. The performance of instruments is highly variable for electronic and mechanical performance, radiation response, susceptibility to interferences and response to environmental factors. Poor instrument performance in these areas can lead to errors or poor accuracy in measurements

    In order to improve students’ motivation, the SIEM (School of Information Environment Method) which is the education method for the introduction of the computer programming education was developed. We focus on students’ motivation, and we have measured students’ motivation as the educational effects. After the SIEM was developed in the School of Information Environment, it applied to introduction to the computer programming education in the School of Engineering Evening Division at the Department of Electrical and Electronic Engineering. It is effective for the improvement of students’ motivation. By adding the Customer Satisfaction Analysis to the SIEM Analysis, it was able to clarify the priority level of the SIEM assessment item. In this paper, we describe results of the Customer Satisfaction Analysis.

    The detectors used in the TS93 balloon flight produced a large volume of information for each cosmic ray trigger. Some of the data was visual in nature, other portions contained energy deposition and timing information. The data sets are amenable to conventional analysis techniques but there is no assurance that conventional techniques make full use of subtle correlations and relations amongst the detector responses. With the advent of neural network technologies, particularly adept at classification of complex phenomena, it would seem appropriate to explore the utility of neural network techniques to classify particles observed with the instruments. In this paper neural network based methodology for signal/background discrimination in a cosmic ray space experiment is discussed. Results are presented for electron and positron classification in the TS93 flight data set and will be compared to conventional analyses.

    In situ exploration of the solar system to identify its early chemistry as preserved in icy bodies and to look for compelling evidence of astrobiology will require new technology for chemical analysis. Chemical measurements in space flight environments highlight the need for a high level of positive identification of chemical compounds, since re-measurement by alternative techniques for confirmation will not be feasible. It also may not be possible to anticipate all chemical species that are observed, and important species may be present only at trace levels where they can be masked by complex chemical backgrounds. Up to now, the only techniques providing independent sample identification of GC separated components across a wide range of chemical species have been Mass Spectrometry (MS) and Ion Mobility Spectrometry (IMS). We describe here the development of a versatile and robust miniature GC detector based on Penning Ionization Electron Spectroscopy (PIES), for use with miniature GC systems being developed for planetary missions. PIES identifies the sample molecule through spectra related to its ionization potential. The combination of miniature GC technology with the primary identification capabilities of PIES provides an analytical approach ideal for planetary analyses.

    A commercial electronic tongue was used to discriminate Korean rice wines (makgeolli) brewed from nine cultivars of rice with different amino acid and fatty acid compositions. The E-tongue was applied to establish prediction models with sensory evaluation or LC-MS/MS by partial least squares regression (PLSR). All makgeollis were classified into three groups by principal components analysis, and the separation pattern was affected by rice qualities and yeast fermentation. Makgeolli taste changed from the complicated comprising sweetness, saltiness, and umami to the uncomplicated, such as bitterness and then, sourness, with a decrease of amino acids and fatty acids in the rice. The quantitative correlation between E-tongue and sensory scores or LC-MS/MS by PLSR demonstrated that E-tongue could well predict most of the sensory attributes with relatively acceptable r(2), except for bitterness, but could not predict most of the chemical compounds responsible for taste attributes, except for ribose, lactate, succinate, and tryptophan.

    To examine the impact of an electronic Results Acknowledgement (eRA) system on emergency physicians' test result management work processes and the time taken to acknowledge microbiology and radiology test results for patients discharged from an Emergency Department (ED). The impact of the eRA system was assessed in an Australian ED using: a) semi-structured interviews with senior emergency physicians; and b) a time and motion direct observational study of senior emergency physicians completing test acknowledgment pre and post the implementation of the eRA system. The eRA system led to changes in the way results and actions were collated, stored, documented and communicated. Although there was a non-significant increase in the average time taken to acknowledge results in the post period, most types of acknowledgements (other than simple acknowledgements) took less time to complete. The number of acknowledgements where physicians sought additional information from the Electronic Medical Record (EMR) rose from 12% pre to 20% post implementation of eRA. Given that the type of results are unlikely to have changed significantly across the pre and post implementation periods, the increase in the time physicians spent accessing additional clinical information in the post period likely reflects the greater access to clinical information provided by the integrated electronic system. Easier access to clinical information may improve clinical decision making and enhance the quality of patient care. For instance, in situations where a senior clinician, not initially involved in the care process, is required to deal with the follow-up of non-normal results. Copyright © 2016 Elsevier Ireland Ltd.

    Full Text Available Introduction: There is a paucity of literature supporting the use of electronic alerts for patients with high frequency emergency department (ED use. We sought to measure changes in opioid prescribing and administration practices, total charges and other resource utilization using electronic alerts to notify providers of an opioid-use care plan for high frequency ED patients. Methods: This was a randomized, non-blinded, two-group parallel design study of patients who had 1 opioid use disorder and 2 high frequency ED use. Three affiliated hospitals with identical electronic health records participated. Patients were randomized into “Care Plan” versus “Usual Care groups”. Between the years before and after randomization, we compared as primary outcomes the following: 1 opioids (morphine mg equivalents prescribed to patients upon discharge and administered to ED and inpatients; 2 total medical charges, and the numbers of; 3 ED visits, 4 ED visits with advanced radiologic imaging (computed tomography [CT] or magnetic resonance imaging [MRI] studies, and 5 inpatient admissions. Results: A total of 40 patients were enrolled. For ED and inpatients in the “Usual Care” group, the proportion of morphine mg equivalents received in the post-period compared with the pre-period was 15.7%, while in the “Care Plan” group the proportion received in the post-period compared with the pre-period was 4.5% (ratio=0.29, 95% CI [0.07-1.12]; p=0.07. For discharged patients in the “Usual Care” group, the proportion of morphine mg equivalents prescribed in the post-period compared with the pre-period was 25.7% while in the “Care Plan” group, the proportion prescribed in the post-period compared to the pre-period was 2.9%. The “Care Plan” group showed an 89% greater proportional change over the periods compared with the “Usual Care” group (ratio=0.11, 95% CI [0.01-0.092]; p=0.04. Care plans did not change the total charges, or, the numbers

    Patient surveys and research have shown that Emergency Department attendees do not receive adequate analgesia. Pain monitoring has not been automated and usually involves a member of staff asking the patient to rate their score with no continuous record, often no specific place to record it and no automated alarm system for scores outside accepted parameters. Few patients have regular monitoring of their pain and our own preliminary research showed that over one week only 58% of patients with moderate to severe pain had a second or subsequent score recorded. A small pain monitoring display has been developed at the University of Leicester and acts as an electronic version of the 11 point numerical rating scale. Data are transmitted to a tablet through a wireless connexion. PIMPERNEL (Patient Input Monitoring of Pain in the Emergency Room: Novel Electronic Log) is a feasibility study testing this for the first time. The primary objective is to determine the feasibility of studying the effect of an electronic pain monitoring display on the pain experienced by emergency care patients. Secondary objectives include determining whether patients use the display, whether pain ratings correlate with routine records, how pain changes over time, whether patients use the display for reasons other than pain, which potential stratification factors may be useful for a subsequent multi-centre study and whether analgesia prescription changes. We will also obtain patient and staff feedback. Adults, initial pain score 5 or more, likely to be staying for at least 2 hours, able to consent and understand English. We aim to recruit 200 patients (100 per arm) from the emergency department at Leicester Royal Infirmary. All patients will use the display. This is a parallel group, two arm superiority trial with a 1:1 allocation ratio. Patients will be randomised to have their pain score on display (intervention) or hidden (control). Blinding is not possible. The display beeps every 15

    This in vitro investigation aimed to study by means of scanning electron microscope the morphological changes in hard dental tissues after using several different methods for caries removal and cavity preparation. Twenty freshly extracted human teeth with carious lesions were used in the study. They were assigned to four groups depending on the method used for preparation: Group 1--Cavity preparation using Er: YAG laser (LiteTouch, Syneron, Israel). Group 2--Chemomechanical preparation using colourless Carisolv gel (MediTeam AB, Savedalen, Sweden). Group 3--Mechanical rotary preparation using diamond burs and air turbine. Group 4--Mechanical rotary preparation using by steel burs and micromotor. The preparations were performed strictly according to the manufacturer's instructions for proper use of instruments. The teeth samples were prepared for histological study and investigated by a scanning electron microscope at different magnification; the morphological changes in the tissues were registered and compared. There were considerable differences in the surface characteristics of the dental tissues when we analysed the photomicrographs of the specimens obtained using scanning electron microscopy (SEM). The surface after laser treatment remained highly retentive with no residual smear layer; the second best results in this respect were registered when teeth were chemomechanically excavated with Carisolv gel. The mechanical methods of cavity preparation resulted in surfaces with a smear layer of dentin without any microretentions. The scanning electron microscopy of hard dental tissues prepared using steel and diamond burs showed surfaces covered with a thick smear layer that may be relevant to the subsequent bonding of adhesive restorative materials to the prepared cavity. In preparing the surface using a turbine with diamond burs the smear layer was thinner and part of the dentinal tubules orifices were open in the area of water turbulence. SEM analysis of hard

    The purpose of this study was to assess and describe the patient inflow during a 1-month period in a Danish emergency department and to evaluate if the intended times to treatment (TTT) related to category of triage were met. Data from electronic emergency screen boards were extracted from the 1st to the 30th of April 2013. 2000 patients were enrolled of which 1011 were eligible for inclusion in the study of TTT. Patient inflow was described according to hours of the day and days of the week. Patients were divided into groups of triage and TTT was assessed in the different groups. Adjusted odds ratios of not being seen on time were calculated between triage groups and time of the day/week. The pattern of inflow differed between weekdays and weekends. On weekdays it peaked around midday and on weekends it peaked during the late afternoon/evening. The distributions of the different triage categories between days were similar. Monday had the most patient contacts while Saturday showed the least. Category II (orange) patients were the most prone to exceed the intended TTT. The risk of not being seen on time when compared to daytime, was on evenings OR 2.3 [1.1;4.9] and on nights OR 2.0 [1.2;3.9]. On weekends the odds ratio was OR 1.9 [0.8;4.7] compared to weekdays. The results demonstrated varying patterns of patient inflow between weekdays and weekends. There was a significantly increased risk of being attended late when arriving on evenings and nights. Likewise higher acuity was associated with exceeded TTT.

    Measuring What Matters identified quality indicators to examine the percentage of patients with documentation of a surrogate decision maker and preferences for life-sustaining treatments. To determine the rate of advance care planning in older adults presenting to the emergency department (ED) and translation into medical directives in the electronic medical record (EMR). A convenience sample of adults 65 years or older was recruited from a large urban ED beginning in January 2012. We administered a baseline interview and survey in English or Spanish, including questions about whether patients had a documented health care proxy or living will. For patients admitted to the hospital who had a health care proxy or living will, chart abstraction was performed to determine whether their advance care preferences were documented in the EMR. From February 2012 to May 2013, 53.8% (367 of 682) of older adults who completed the survey in the ED reported having a health care proxy, and 40.2% (274 of 682) had a living will. Of those admitted to the hospital, only 4% (4 of 94) of patients who said they had a living will had medical directives documented in the EMR. Similarly, only 4% (5 of 115) of patients who had a health care proxy had the person's name or contact information documented in their medical record. About half of the patients 65 years or older arriving in the ED have done significant advance care planning, but most plans are not recorded in the EMR.

    RFS or Regles Fondamentales de Surete (Basic Safety Rules) applicable to certain types of nuclear facilities lay down requirements with which compliance, for the type of facilities and within the scope of application covered by the RFS, is considered to be equivalent to compliance with technical French regulatory practice. The object of the RFS is to take advantage of standardization in the field of safety, while allowing for technical progress in that field. They are designed to enable the operating utility and contractors to know the rules pertaining to various subjects which are considered to be acceptable by the Service Central de Surete des Installations Nucleaires, or the SCSIN (Central Department for the Safety of Nuclear Facilities). These RFS should make safety analysis easier and lead to better understanding between experts and individuals concerned with the problems of nuclear safety. The SCSIN reserves the right to modify, when considered necessary, any RFS and specify, if need be, the terms under which a modification is deemed retroactive. The aim of this RFS is to define the type, location and operating conditions for seismic instrumentation needed to determine promptly the seismic response of nuclear power plants features important to safety to permit comparison of such response with that used as the design basis

    Numerous fire PSAs (probabilistic safety assessments) have shown that fire can be a major contributor to nuclear power plant risk. However, there are considerable uncertainties in the results of these assessments, due to significant gaps in current abilities to perform realistic assessments. These gaps involve multiple aspects of fire PSA, including the estimation of the probability of important fire scenarios, the modeling of fire growth and suppression, the prediction of fire-induced damage to equipment (including the effects of smoke), and the treatment of plant and operator responses to the fire. In response to recommendations of /VIR 93/, CSNI/PWG5 established a Task Group to review the present status and maturity of current methods used in fire risk assessments for operating nuclear power plants. The Task Group issued a questionnaire in May 1997 to all nuclear power generating OECD countries. The prime focus of the questionnaire (see Appendix A) was on a number of important issues in fire PSA: Fire PSA methodology and applications; Fire simulation codes; Ignition and damageability data; Modeling of fire spread on cables or other equipment; Modeling of smoke production and spread; Impact of smoke and heat on instrumentation, electronics, or other electrical equipment; Impact of actual cable fires on safety systems. The questionnaire requested specific information on these topics (e.g., computer codes used in fire PSAs, the physical parameters used to model ignition). Responses to the questionnaire were provided by Finland, France, Germany, Hungary, Japan, Spain, Switzerland, United Kingdom, and the USA. This report summarizes the questionnaire responses and thereby: a) provides a perspective on the current fire PSA state of the art (SOAR) with respect to the issues listed above, and b) provides numerous references for more detailed information regarding these issues. The main responsibility for writing different chapters of this report was divided between some

    Emergency departments (EDs) have implemented HIV screening using a variety of strategies. This study investigates how specific patient and health system factors in the ED impact who is and is not screened in a combined targeted and nontargeted, electronic medical record (EMR)-driven, opt-out, HIV screening program. This was a retrospective, cross-sectional study of ED visits where patients were determined eligible for HIV screening by an EMR algorithm between November 18, 2014, and July 15, 2015. The HIV screening workflow included three sequential events, all of which were required to get screened for HIV at the ED visit. The events were having a blood draw, being informed of the HIV screening policy by an ED nurse at the point of blood draw, and the patient consenting to the HIV test. Each event represented a dichotomous outcome and its association with six patient factors (age, sex, race/ethnicity, marital status, preferred language, and Emergency Severity Index [ESI]) and two health system factors (ED crowding and program phase) was investigated using multivariable modeling. A total of 15,918 ED visits were analyzed. Blood was drawn in 8,388 of 15,918 visits (53%). Of 8,388 visits where blood was drawn, there were 5,947 (71%) visits where ED nurses documented informing patients of the HIV screening policy. Of those visits, patient consent to the HIV test was documented at 3,815 (64%) visits. Patients between 13 and 19 years of age were significantly less likely to have blood drawn, to be informed of the screening policy, and to consent to the HIV test compared to other age groups. Both ED crowding and a patient's ESI were associated with decreased odds of having a blood draw and being informed of HIV screening by an ED nurse, but showed no association with patients consenting to the HIV test. Many patients, particularly adolescents and young adults, are missed in ED HIV screening programs that require blood draw and depend on providers to obtain consent for

    All electronic test and measuring systems and process control instruments constitute a critical and important area of instrumentation in the nuclear and conventional power plant, process plant and research laboratories. All these instruments need periodic calibration. Therefore standards laboratories is one of the essential tools in enforcing quality. Calibration of these instruments plays a vital role in the performance, reliability, and quality of the target to be achieved. Thus calibration is a must if need speed and quality. (author)

    This study aimed to evaluate superficial defects and the composition of Reciproc R25 and ProTaper Retreatment file systems (Dentsply Maillefer, Ballaigues, Switzerland) used for retreatment. A total of 100 maxillary incisor teeth were randomly divided into the following two groups: Reciproc R25 (n = 25) and ProTaper Retreatment instrument (n = 75) groups. The nickel-titanium (Ni-Ti) compositions of the files before and after use were analyzed using energy dispersive X-ray spectrophotometry (EDX). Chi-square, Mann-Whitney U, and Kruskal-Wallis tests were used to analyze the data. ProTaper Retreatment instrument group showed a significantly higher number of defects than the Reciproc group (P < 0.05). No instrument fracture was detected. The presence of debris was observed in both groups before use, although the level was significantly higher in the ProTaper Retreatment group, which consisted of metals (P < 0.05). There was no significant difference between new and used instruments with regard to Ni-Ti composition (P < 0.05). EDX analysis showed that both the Reciproc and ProTaper Retreatment instruments had a Ni-Ti composition that was within the standards specified by the American Society of Testing and Materials. This study confirmed the use of both the Reciproc R25 file and ProTaper Retreatment file system for root canal filling removal in straight root canals as a safe procedure.

    Context. In the past decade, sensitive, resolved Sunyaev-Zel'dovich (SZ) studies of galaxy clusters have become common. Whereas many previous SZ studies have parameterized the pressure profiles of galaxy clusters, non-parametric reconstructions will provide insights into the thermodynamic state of the intracluster medium. Aim. We seek to recover the non-parametric pressure profiles of the high redshift (z = 0.89) galaxy cluster CLJ 1226.9+3332 as inferred from SZ data from the MUSTANG, NIKA, Bolocam, and Planck instruments, which all probe different angular scales. Methods: Our non-parametric algorithm makes use of logarithmic interpolation, which under the assumption of ellipsoidal symmetry is analytically integrable. For MUSTANG, NIKA, and Bolocam we derive a non-parametric pressure profile independently and find good agreement among the instruments. In particular, we find that the non-parametric profiles are consistent with a fitted generalized Navaro-Frenk-White (gNFW) profile. Given the ability of Planck to constrain the total signal, we include a prior on the integrated Compton Y parameter as determined by Planck. Results: For a given instrument, constraints on the pressure profile diminish rapidly beyond the field of view. The overlap in spatial scales probed by these four datasets is therefore critical in checking for consistency between instruments. By using multiple instruments, our analysis of CLJ 1226.9+3332 covers a large radial range, from the central regions to the cluster outskirts: 0.05 R500 generation of SZ instruments such as NIKA2 and MUSTANG2.

    Recognizing that the University Reactor Instrumentation Program was developed in response to widespread needs in the academic community for modernization and improvement of research and training reactors at institutions such as the University of Florida, the items proposed to be supported by this grant over its two year period have been selected as those most likely to reduce foreed outages, to meet regulatory concerns that had been expressed in recent years by Nuclear Regulatory Commission inspectors or to correct other facility problems and limitations. Department of Energy Grant Number DE-FG07-90ER129969 was provided to the University of Florida Training Reactor(UFTR) facility through the US Department of Energy's University Reactor Instrumentation Program. The original proposal submitted in February, 1990 requested support for UFTR facility instrumentation and equipment upgrades for seven items in the amount of $107,530 with $13,800 of this amount to be the subject of cost sharing by the University of Florida and $93,730 requested as support from the Department of Energy. A breakdown of the items requested and total cost for the proposed UFTR facility instrumentation and equipment improvements is presented

    1997-01-01

    A benchtop virtual instrument simulator for CERES (Clouds and the Earth's Radiant Energy System) has been built at NASA, Langley Research Center in Hampton, VA. The CERES instruments will fly on several earth orbiting platforms notably NASDA's Tropical Rainfall Measurement Mission (TRMM) and NASA's Earth Observing System (EOS) satellites. CERES measures top of the atmosphere radiative fluxes using microprocessor controlled scanning radiometers. The CERES Virtual Instrument Simulator consists of electronic circuitry identical to the flight unit's twin microprocessors and telemetry interface to the supporting spacecraft electronics and two personal computers (PC) connected to the I/O ports that control azimuth and elevation gimbals. Software consists of the unmodified TRW developed Flight Code and Ground Support Software which serves as the instrument monitor and NASA/TRW developed engineering models of the scanners. The CERES Instrument Simulator will serve as a testbed for testing of custom instrument commands intended to solve in-flight anomalies of the instruments which could arise during the CERES mission. One of the supporting computers supports the telemetry display which monitors the simulator microprocessors during the development and testing of custom instrument commands. The CERES engineering development software models have been modified to provide a virtual instrument running on a second supporting computer linked in real time to the instrument flight microprocessor control ports. The CERES Instrument Simulator will be used to verify memory uploads by the CERES Flight Operations TEAM at NASA. Plots of the virtual scanner models match the actual instrument scan plots. A high speed logic analyzer has been used to track the performance of the flight microprocessor. The concept of using an identical but non-flight qualified microprocessor and electronics ensemble linked to a virtual instrument with identical system software affords a relatively inexpensive

    Full Text Available Modern devices with optical elements for measurement and thermal control of different physical nature objects subjected to intense external thermal actions. To prevent destruction of optical elements the electron beam methods of work surfaces finishing at the stage of manufacture has practical significance. These methods can improve the properties of the element surface layers and thus make them more resistant to external thermal and mechanical action. Aim: The aim is to determine the optimal ranges of parameters of the electron beam and the development of experimental and statistical models that will automatically generate database with improved properties of the surface layers of optical elements in real time mode after previous electron beam treatment. Materials and Methods: To study the influence of parameters of the electron beam on the properties of the surface layers of the optical elements used plates of optical glass (K8, K108, etc. and ceramics (KO1, KO2, etc.. The strip electron beam has the following characteristics: density of heat flow Fn = 5∙10^6…9∙10^8 W/m2 and rate of displacement V = 0…0.1 m/s. Determination of the surface layers properties of the optical elements before and after electron beam treatment was carried out by known methods of physical and chemical analysis. Results: It was established that under the influence of the electron beam on the surface of the optical element there is visible clearing of various impurities take place, various micro-defects that remain on it after standard processing methods (mechanical, chemical, etc. remove and also its smoothness significantly increases, i.e. height of residual asperities on the surface is reduced. It was also found that the processing of optical glass elements by electron beam their surface layers change their structure, which is close to the quartz. It is shown that the surface of the preprocessed electron beam elements able to withstand the critical value of

    Future trends in the development of radiation protection instrumentation can be expected to be closely related to current trends in political and social activity that drive legislation, rule-making, and standard practice, with assistance provided by trends in material and electronic technology. Wide-range performance will be emphasized to arm the daily worker with instruments that routinely log background rates and, at the same time, are prepared to measure accident rates. Separate and simultaneous accumulation of data from several sensors to ensure complete coverage of the radiation types will be common. Mathematical manipulation of data will provide for summary data logging and, in some cases, solutions to integral equations to provide corrections to experimental data. Instruments will become more reliable by way of self-checking and correction. Miniaturization and large-scale integration of measuring instruments will provide some instrumentation for the people at large. To be effective, the instruments will necessarily cover a wide range and be very reliable. The net result of these several trends will provide for a widespread understanding of radiation protection and an implementation of as low as reasonably achievable among large segments of the population

    Calorimetric particle detectors that play an important role in high-energy cosmic-ray balloon and satellite experiments not only have the major task of measuring energy but also face the problem of identifying electrons and protons. This problem is usually solved by measuring the longitudinal and traverse shower profiles and the total energy release in the calorimeter, using the fact that electromagnetic and hadronic showers differ in their spatial and energy distributions. In this paper, electron and proton identification methods for different types of calorimeters used in cosmic-ray balloon- and satellite-borne experiments are discussed.

    Some classical old fashioned instruments (such as the Wood-Anderson seismometers), as well as some modern instruments (like the all-quartz made Verbaandert-Melchior tiltmeters), conventionally require an impractical recording system obtained by a photographic drum recorder in a darkroom. Simple electronic equipment (made by readily available, low cost electronics) may help in using such kind of instruments allowing a useful digital recording. This will reduce the time-hour in data acquisition and storage (and the manual error) and will increase the accuracy. The theory of operations and some results obtained using the described equipment are shown.

Due to an absence of clinical biomarkers for IBS-D severity, evaluation of clinical therapy benefits depends on valid and reliable symptom assessments. A patient-reported outcome (PRO instrument has been developed, comprising of two questionnaires – the IBS-D Daily Symptom Diary and IBS-D Symptom Event Log – suitable for clinical trials and real-world settings. This program aimed to support instrument conversion from pen-and-paper to electronic format.Materials and methods: Digital technology (Android/iOS and a traditional mode of administration study in the target population were used to migrate or convert the validated PRO IBS-D pen-and-paper measure to an electronic format. Equivalence interviews, conducted in three waves, each had three parts: 1 conceptual equivalence testing between formats, 2 electronic-version report-history cognitive debriefing, and 3 electronic version usability evaluation. After each interview wave, preliminary analyses were conducted and modifications made to the electronic version, before the next wave. Final revisions were based on a full analysis of equivalence interviews. The final analysis evaluated subjects’ ability to read, understand, and provide meaningful responses to the instruments across both formats. Responses were classified according to conceptual equivalence between formats and mobile-format usability assessed with a questionnaire and open-ended probes.Results: Equivalence interviews (n=25 demonstrated conceptual equivalence between formats.

    At this year's particle physics conference at Brighton, a parallel session was given over to instrumentation and detector development. While this work is vital to the health of research and its continued progress, its share of prime international conference time is limited. Instrumentation can be innovative three times — first when a new idea is outlined, secondly when it is shown to be feasible, and finally when it becomes productive in a real experiment, amassing useful data rather than operational experience. Hyams' examples showed that it can take a long time for a new idea to filter through these successive stages, if it ever makes it at all

    NERSC recently undertook a project to access and analyze Secure Shell (SSH) related data. This includes authentication data such as user names and key fingerprints, interactive session data such as keystrokes and responses, and information about noninteractive sessions such as commands executed and files transferred. Historically, this data has been inaccessible with traditional network monitoring techniques, but with a modification to the SSH daemon, this data can be passed directly to intrusion detection systems for analysis. The instrumented version of SSH is now running on all NERSC production systems. This paper describes the project, details about how SSH was instrumented, and the initial results of putting this in production.

    For better understanding of the specification for seismic instrumentation of a nuclear power plant, the lecture gives some fundamental remarks to the seismic risk in the Federal Republic of Germany and to the data characterizing an earthquake event. Coming from the geophysical properties of an earthquake, the quantities are explained which are used in the design process of nuclear power plants. This process is shortly described in order to find the requirements for the specification of the seismic instrumentation. In addition the demands of licensing authorities are given. As an example the seismic instrumentation of KKP-1, BWR, is shown. The paper deals with kind and number of instruments, their location in the plant and their sensitivity and calibration. Final considerations deal with the evaluation of measured data and with plant operation after an earthquake. Some experience concerning the earthquake behaviour of equipment not designed to withstand earthquake loads is mentioned. This experience has initiated studies directed to quantification of the degree of conservatism of the assumptions in the seismic design of nuclear power plants. A final garget of these studies are more realistic design rules. (RW)

    1988-01-01

    The second edition of Instrumental Analysis is a survey of the major instrument-based methods of chemical analysis. It appears to be aimed at undergraduates but would be equally useful in a graduate course. The volume explores all of the classical quantitative methods and contains sections on techniques that usually are not included in a semester course in instrumentation (such as electron spectroscopy and the kinetic methods). Adequate coverage of all of the methods contained in this book would require several semesters of focused study. The 25 chapters were written by different authors, yet the style throughout the book is more uniform than in the earlier edition. With the exception of a two-chapter course in analog and digital circuits, the book purports to de-emphasize instrumentation, focusing more on the theory behind the methods and the application of the methods to analytical problems. However, a detailed analysis of the instruments used in each method is by no means absent. The book has the favor of a user's guide to analysis

    As a part of a design study for the On-Instrument Low Order Wave-front Sensor (OIWFS) for the TMT Infra-Red Imaging Spectrograph (IRIS), we recently evaluated the noise performance of a detector control system consisting of IUCAA SIDECAR DRIVE ELECRONICS CONTROLLER (ISDEC), SIDECAR ASIC and HAWAII-2RG (H2RG) MUX. To understand and improve the performance of this system to serve as a near infrared wavefront sensor, we implemented new read out modes like multiple regions of interest with differential multi-accumulate readout schemes for the HAWAII-2RG (H2RG) detector. In this system, the firmware running in SIDECAR ASIC programs the detector for ROI readout, reads the detector, processes the detector output and writes the digitized data into its internal memory. ISDEC reads the digitized data from ASIC, performs the differential multi-accumulate operations and then sends the processed data to a PC over a USB interface. A special loopback board was designed and used to measure and reduce the noise from SIDECAR ASIC DC biases2. We were able to reduce the mean r.m.s read noise of this system down to 1-2 e. for any arbitrary window frame of 4x4 size at frame rates below about 200 Hz.

  11. Virtual Sensor Test Instrumentation

    2011-01-01

    Virtual Sensor Test Instrumentation is based on the concept of smart sensor technology for testing with intelligence needed to perform sell-diagnosis of health, and to participate in a hierarchy of health determination at sensor, process, and system levels. A virtual sensor test instrumentation consists of five elements: (1) a common sensor interface, (2) microprocessor, (3) wireless interface, (4) signal conditioning and ADC/DAC (analog-to-digital conversion/ digital-to-analog conversion), and (5) onboard EEPROM (electrically erasable programmable read-only memory) for metadata storage and executable software to create powerful, scalable, reconfigurable, and reliable embedded and distributed test instruments. In order to maximize the efficient data conversion through the smart sensor node, plug-and-play functionality is required to interface with traditional sensors to enhance their identity and capabilities for data processing and communications. Virtual sensor test instrumentation can be accessible wirelessly via a Network Capable Application Processor (NCAP) or a Smart Transducer Interlace Module (STIM) that may be managed under real-time rule engines for mission-critical applications. The transducer senses the physical quantity being measured and converts it into an electrical signal. The signal is fed to an A/D converter, and is ready for use by the processor to execute functional transformation based on the sensor characteristics stored in a Transducer Electronic Data Sheet (TEDS). Virtual sensor test instrumentation is built upon an open-system architecture with standardized protocol modules/stacks to interface with industry standards and commonly used software. One major benefit for deploying the virtual sensor test instrumentation is the ability, through a plug-and-play common interface, to convert raw sensor data in either analog or digital form, to an IEEE 1451 standard-based smart sensor, which has instructions to program sensors for a wide variety of

    This study compared the torsional resistance of two brands of rotary nickel-titanium (NiTi) instruments indicated for endodontic retreatment. Mtwo retreatment instruments #15 and #25 (VDW, Munich, Germany) and ProTaper Universal retreatment instruments D2 and D3 (Maillefer/Dentsply, Ballaigues, Switzerland) were subjected to a torsional assay in clockwise rotation. The two parameters evaluated were maximum torque and angular deflection at failure. Fractured instruments had their fractured surfaces and helical shafts examined by scanning electron microscopy. The results indicated that the angular deflection at fracture decreased in the following order: Mtwo retreatment file #15 > Mtwo retreatment file #25 > ProTaper Universal retreatment file D2 > ProTaper Universal retreatment file D3. As for the maximum torque values, the results revealed the following descending order: ProTaper Universal file D2 > Mtwo retreatment file #25 > ProTaper Universal file D3 > Mtwo retreatment file #15. Scanning electron microscopic analysis revealed that plastic deformation occurred along the helical shaft of the fractured instruments. Fractured surfaces were of the ductile type. The instruments tested showed different torsional behavior depending on the parameter evaluated. If one considers that high angular deflection values may serve as a safety factor, then the Mtwo retreatment instruments showed significantly better results.

    The Low Energy Ion Ring (LEIR) is central to the “Ions for LHC” project. Its role is to transform a serie of long low intensity ion pulses from Linac 3, into short high density pulses, which will be further accelerated in the PS and SPS rings, before injection into LHC. To do so the injected pulses are stacked and phase space cooled using electron cooling, before acceleration to the ejection energy of 72 MEV/u. This note describes different types of instruments which will be installed in the LEIR ring and transfer lines.

    The Internet, with its capacity to provide information that transcends time and space barriers, continues to transform how people find and apply information to their own lives. With the current explosion in electronic sources of health information, including thousands of websites and hundreds of mobile phone health apps, electronic health literacy is gaining an increasing prominence in health and medical research. An important dimension of electronic health literacy is the ability to appraise the quality of information that will facilitate everyday health care decisions. Health information seekers explore their care options by gathering information from health websites, blogs, Web-based forums, social networking websites, and advertisements, despite the fact that information quality on the Internet varies greatly. Nonetheless, research has lagged behind in establishing multidimensional instruments, in part due to the evolving construct of health literacy itself. The purpose of this study was to examine psychometric properties of a new electronic health literacy (ehealth literacy) measure in a national sample of Internet users with specific attention to older users. Our paper is motivated by the fact that ehealth literacy is an underinvestigated area of inquiry. Our sample was drawn from a panel of more than 55,000 participants maintained by Knowledge Networks, the largest national probability-based research panel for Web-based surveys. We examined the factor structure of a 19-item electronic Health Literacy Scale (e-HLS) through exploratory factor analysis (EFA) and confirmatory factor analysis, internal consistency reliability, and construct validity on sample of adults (n=710) and a subsample of older adults (n=194). The AMOS graphics program 21.0 was used to construct a measurement model, linking latent factors obtained from EFA with 19 indicators to determine whether this factor structure achieved a good fit with our entire sample and the subsample (age ≥ 60

    The photo shows a close-up of a Lichtenberg figure – popularly called an “electron tree” – produced in a cylinder of polymethyl methacrylate (PMMA). Electron trees are created by irradiating a suitable insulating material, in this case PMMA, with an intense high energy electron beam. Upon discharge......, during dielectric breakdown in the material, the electrons generate branching chains of fractures on leaving the PMMA, producing the tree pattern seen. To be able to create electron trees with a clinical linear accelerator, one needs to access the primary electron beam used for photon treatments. We...... appropriated a linac that was being decommissioned in our department and dismantled the head to circumvent the target and ion chambers. This is one of 24 electron trees produced before we had to stop the fun and allow the rest of the accelerator to be disassembled....

    Kamel, Wael H; Kataia, Engy M

    2014-03-01

    The aim of this study was to compare by scanning electron microscopy the presence of smear layer and debris on root canal walls after preparation with the single-file system WaveOne (Dentsply Maillefer, Ballaigues, Switzerland) versus the rotary ProTaper system (Dentsply Maillefer, Ballaigues, Switzerland) under 2 final irrigant regimens. Forty freshly extracted single-rooted human teeth were randomly divided into 4 groups (n = 10). The ProTaper and ProTaper and rotary CanalBrush (Coltène Whaledent GmbH+ Co KG, Langenau, Germany) groups were instrumented with the ProTaper system. Groups WaveOne and WaveOne and rotary CanalBrush were instrumented with the WaveOne system. The irrigant in all groups was 2 mL 5.25% sodium hypochlorite (NaOCl) solution, whereas the final irrigation after preparation in the ProTaper and WaveOne groups was 1 mL Smear Clear solution (Sybron Endo, Orange, CA) and then 5.25% NaOCl applied with a plastic syringe, and in the ProTaper and rotary CanalBrush and WaveOne and rotary CanalBrush groups, it was 1 mL Smear Clear solution and then 5.25% NaOCl (rotary CanalBrush agitation). Roots were processed for scanning electron microscopic examination for debris and smear layer scoring. Data were statistically analyzed. All groups showed more efficient smear layer and debris removal coronally than in the middle and apical regions, whereas the mean total debris score and the mean smear layer score in all groups were less in the WaveOne and rotary CanalBrush groups than the ProTaper and rotary CanalBrush and the WaveOne and ProTaper groups. Using the rotary CanalBrush in canals prepared with WaveOne produced the cleanest canal walls, and the WaveOne system gave superior results compared with the ProTaper system.

    Translating Emergency Knowledge for Kids was established to bridge the research-practice gap in pediatric emergency care by bringing the best evidence to Canadian general emergency departments (EDs). The first step in this process was to conduct a national needs assessment to determine the information needs and preferences of health professionals and parents in this clinical setting. To describe the development and implementation of two electronic surveys, and determine the feasibility of collecting electronic survey data on iPads with in-person data collectors in a busy clinical environment. Two descriptive surveys were conducted in 32 general EDs. Specific factors were addressed in four survey development and implementation stages: survey design, survey delivery, survey completion, and survey return. Feasibility of the data collection approach was determined by evaluating participation rates, completion rates, average survey time to completion, and usability of the platform. Usability was assessed with the in-person data collectors on five key variables: interactivity, portability, innovativeness, security, and proficiency. Health professional participation rates (1561/2575, 60.62%) and completion rates (1471/1561, 94.23%) were strong. Parental participation rates (974/1099, 88.63%) and completion rates (897/974, 92.09%) were excellent. Mean time to survey completion was 28.08 minutes for health professionals and 43.23 minutes for parents. Data collectors rated the platform "positively" to "very positively" on all five usability variables. A number of design and implementation considerations were explored and integrated into this mixed-mode survey data collection approach. Feasibility was demonstrated by the robust survey participation and completion rates, reasonable survey completion times, and very positive usability evaluation results.

    Sports- and recreation-related traumatic brain injuries (SRR-TBIs) are a growing public health problem affecting persons of all ages in the United States. To describe the trends of SRR-TBIs treated in US emergency departments (EDs) from 2001 to 2012 and to identify which sports and recreational activities and demographic groups are at higher risk for these injuries. Data on initial ED visits for an SRR-TBI from the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP) for 2001-2012 were analyzed. NEISS-AIP data are drawn from a nationally representative sample of hospital-based EDs. Cases of TBI were identified from approximately 500,000 annual initial visits for all causes and types of injuries treated in EDs captured by NEISS-AIP. Numbers and rates by age group, sex, and year were estimated. Aggregated numbers and percentages by discharge disposition were produced. Approximately 3.42 million ED visits for an SRR-TBI occurred during 2001-2012. During this period, the rates of SRR-TBIs treated in US EDs significantly increased in both males and females regardless of age (all Ps sports and recreational activity, age, and sex.

    Full text: The research activity of our department concerns structural and dynamical properties of molecular solids. The particular subjects of interest in the year 2000 were orientational and conformational disorder on organic materials and the magnetism of new molecular and intermetallic compounds. The experimental work in our department relies on the complementary use of large instruments at international research centres and of the equipment operating in our laboratories. In the neutron scattering studies (ICNS inelastic coherent neutron scattering, IINS inelastic incoherent neutron scattering, QNS quasielastic neutron scattering etc) we mostly avail ourselves of neutron sources of The Institute for Energy Technology (IFE), Kjeller, Norway, and of The Joint Institute for Nuclear Research (JINR) Dubna, Russia. Our proposals are also regularly accepted in the other neutron centres such as Leon Brillouin Laboratory (LLB) Saclay, France, Rutherford Appleton Laboratory (RAL) Oxford, UK. etc. Thermodynamic characteristics of the materials are determined in our calorimetric laboratory equipped with adiabatic and differential scanning calorimeters. It is due to the invention of our researchers that these instruments, partly prototypic, are now capable of providing quantitative results on the kinetic behaviour of materials out of equilibrium. The scanning mode operation of our upgraded Fourier-transform infrared spectrometer allows US to follow the evolution of the dynamics of a material in the real time and in the temperature range 10-310 K. Textures arising in phase transitions are observed with the use of the polarising microscope with temperature-controlled stage. Molecular reorientation motions and relaxation processes are studied in the dielectric measurements. The laboratory of magnetic research possesses a set of modern instruments for measurements of magnetisation and of the AC susceptibility operating down to the helium temperatures.

  3. Instrumental fundamental parameters and selected applications of the microfocus X-ray fluorescence analysis at a scanning electron microscope; Instrumentelle Fundamentalparameter und ausgewaehlte Anwendungen der Mikrofokus-Roentgenfluoreszenzanalyse am Rasterelektronenmikroskop

    2012-05-30

    For a decade X-ray sources have been commercially available for the microfocus X-ray fluorescence analysis ({mu}-XRF) and offer the possibility of extending the analytics at a scanning electron microscope (SEM) with an attached energy dispersive X-ray spectrometer (EDS). By using the {mu}-XRF it is possible to determine the content of chemical elements in a microscopic sample volume in a quantitative, reference-free and non-destructive way. For the reference-free quantification with the XRF the Sherman equation is referred to. This equation deduces the intensity of the detected X-ray intensity of a fluorescence peak to the content of the element in the sample by means of fundamental parameters. The instrumental fundamental parameters of the {mu}-XRF at a SEM/EDS system are the excitation spectrum consisting of X-ray tube spectrum and the transmission of the X-ray optics, the geometry and the spectrometer efficiency. Based on a calibrated instrumentation the objectives of this work are the development of procedures for the characterization of all instrumental fundamental parameters as well as the evaluation and reduction of their measurement uncertainties: The algorithms known from the literature for the calculation of X-ray tube spectrum are evaluated with regard to their deviations in the spectral distribution. Within this work a novel semi-empirical model is improved with respect to its uncertainties and enhanced in the low energy range as well as extended for another three anodes. The emitted X-ray tube spectrum is calculated from the detected one, which is measured at an especially developed setup for the direct measurement of X-ray tube spectra. This emitted X-ray tube spectrum is compared to the one calculated on base of the model of this work. A procedure for the determination of the most important parameters of an X-ray semi-lens in parallelizing mode is developed. The temporal stability of the transmission of X-ray full lenses, which have been in regular

  5. Diagnostics and Instrumentation for FEL

    CERN Document Server

    Couprie, M E

    2001-01-01

    Free Electron Laser are coherent sources of radiation based on the interaction of a relativistic electron beam in an undulator field. According to the energy of the accelerator, they presently cover a wide spectral range, from the infra-red to the VUV. FELs combine the diagnostics of typical laser systems (for the measurement of spectral and temporal characteristics, the transverse mode pattern, the polarisation) and the diagnostics of relativistic electron beams. The electron beam is characterised in order to evaluate and control the FEL performances, but also in order to measure the effect of the FEL on the electron beam. The FEL characteristics are monitored with various types of detectors, depending mainly on the spectral range. Diagnostics for Linac based Infra Red FELs and storage ring FELs in the UV-VUV will be described. Particular instrumentation, required for FEL operation, such as the optical resonator, possible diagnostics inside the undulator will also be analysed.

  10. Maintenance of nuclear medicine instruments

    International Nuclear Information System (INIS)

    Ambro, P.

    1992-01-01

    Maintenance of instruments is generally of two kinds: (a) corrective maintenance, on a non-scheduled basis, to restore equipment to a functional status by repairs; (b) preventive maintenance, to keep equipment in a specified functional condition by providing systematic inspection, quality control, detection and correction of early malfunctions. Most of the instruments used in nuclear medicine are rather complex systems built from mechanical, electrical and electronic parts. Any one of these components is liable to fail at some time or other. Repair could be done only by a specialist who is able to evaluate the condition of the various parts ranging from cables to connectors, from scintillators to photomultipliers, from microprocessors to microswitches. The knowledge of the intricacies of the various electronic components required for their repairs is quite wide and varied. The electronics industry turns out more and more multi-purpose chips which can carry out the functions of many parts used in the instruments of the earlier generation. This provides protection against unauthorized copying of the circuits but it serves another purpose as well of inhibiting repairs by non-factory personnel. These trends of the instrument design should be taken into consideration when a policy has to be developed for the repairs of the hospital based equipment

    Full text : Nuclear Instrumentation is a field of vital importance for DAE. It has important applications in many areas of interest such as Reactor Monitoring and control, Accelerator based research, Laser and nuclear physics experiments, Health and environmental monitoring, Astrophysics experiments etc. It is a specialized field involving expertise in detection of radioactivity down to the level of few events per minute as well as processing and analysis of signals which can be as small as few hundred micro volts embedded in noise. Some applications involve digitizing and processing these signals with 0.001% accuracy and timing accuracies of a fraction of nano sec. Rapid developments in semiconductor related technologies have influenced the field of nuclear instrumentation. Development of FPGA's and ASIC's have made it possible to develop miniaturized smart and portable instruments for field applications. Advancements in field of computers, communications and various field buses have been successfully utilized for smart, portable and DSP based instrumentation. Smart sensor with detector and front-end electronics on a single silicon chip is now a reality. These instruments are also made intelligent by addition of fuzzy logic, artificial neural networks and expert systems. Electronics Division of BARC has made significant contribution to the field of nuclear instrumentation to achieve self-reliance in this area. This has also led to development of several new methods, which have been published in international journals and appreciated worldwide. As a step towards achieving complete self-reliance a programme for development of FPGA's, HMC's and ASIC's has been undertaken and is being followed with special emphasis. This also includes development of detector and front- end electronics on a single chip. This talk brings out details of these developments and describes the 'state of art' work done in India

    2012-07-01

    The Q/U Imaging ExperimenT (QUIET) is designed to measure polarization in the Cosmic Microwave Background, targeting the imprint of inflationary gravitational waves at large angular scales ({approx}1{sup o}). Between 2008 October and 2010 December, two independent receiver arrays were deployed sequentially on a 1.4m side-fed Dragonian telescope. The polarimeters which form the focal planes use a highly compact design based on High Electron Mobility Transistors (HEMTs) that provides simultaneous measurements of the Stokes parameters Q, U, and I in a single module. The 17-element Q-band polarimeter array, with a central frequency of 43.1 GHz, has the best sensitivity (69 {mu}Ks{sup 1/2}) and the lowest instrumental systematic errors ever achieved in this band, contributing to the tensor-to-scalar ratio at r < 0:1. The 84-element W-band polarimeter array has a sensitivity of 87 {mu}Ks{sup 1/2} at a central frequency of 94.5 GHz. It has the lowest systematic errors to date, contributing at r < 0:01. The two arrays together cover multipoles in the range {ell} {approx} 25 -- 975. These are the largest HEMT-based arrays deployed to date. This article describes the design, calibration, performance of, and sources of systematic error for the instrument.

    The earliest astronomical instruments used in India were the gnomon and the water clock. In the early seventh century, Brahmagupta described ten types of instruments, which were adopted by all subsequent writers with minor modifications. Contact with Islamic astronomy in the second millennium AD led to a radical change. Sanskrit texts began to lay emphasis on the importance of observational instruments. Exclusive texts on instruments were composed. Islamic instruments like the astrolabe were adopted and some new types of instruments were developed. Production and use of these traditional instruments continued, along with the cultivation of traditional astronomy, up to the end of the nineteenth century.

    2013-01-24

    To describe the demographic characteristics and incidence of unintentional fall-related fractures among older adults treated in the US hospital emergency departments (EDs). Retrospective observational study. Hospitals' ED participants in the National Electronic Injury Surveillance System All Injury Program (NEISS-AIP). The NEISS-AIP was used to generate national estimates of hospital ED visits for unintentional fall-related fracture among adults aged 65 years or older between 2001 and 2008. Census population estimates were used as the denominator to calculate age-specific and age-adjusted fracture rates per 100 000 persons. Fall-related fracture rates and ED disposition. On the basis of 70 199 cases, an estimated 4.05 million older adults were treated in US hospital EDs for fall-related fracture during the 8-year period. Two-thirds of the injuries occurred at home and 69.5% (95% CI 59.7% to 77.8%) of the affected individuals were white. Fall-related fracture rates increased gradually with age and were on average twofold higher among women. Of those hospitalised, women and fractures of the lower trunk represented 75.2% and 65.1% of the admissions, respectively. The estimated number of fall-related fractures treated in EDs increased from 574 500 in 2001 to 714 800 in 2008, a 24.4% increase. By gender, a non-significant upward trend in age-adjusted fall-related fracture rates was predominantly seen among men at an annual rate of 1.9% (95% CI -0.1% to 4.0%), whereas fracture rates among women remained stable at 0.9% (95% CI -0.7% to 2.5%) per year. The oldest old, women and lower trunk fractures account for the majority of fall-related fractures among persons aged 65 years or older treated in US hospital EDs. Increasing ED visits and hospitalisations for fall-related fracture among older adults deserve further research.

    Radiation protection instrumentation plays very important role in radiation protection and surveillance programme. Radiation detector, which appears at the frontal end of the instrument, is an essential component of these instruments. The instrumental requirement of protection level radiation monitoring is different from conventional radiation measuring instruments. Present paper discusses the new type of nuclear radiation detectors, new protection level instruments and associated electronic modules for various applications. Occupational exposure to ionizing radiation can occur in a range of industries, such as nuclear power plants; mining and milling; medical institutions; educational and research establishments; and nuclear fuel cycle facilities. Adequate radiation protection to workers is essential for the safe and acceptable use of radioactive materials for different applications. The radiation exposures to the individual radiation workers and records of their cumulative radiation doses need to be routinely monitored and recorded

    Full text: Promising students had a foretaste of the latest laboratory techniques at the ICFA 1993 India School on Instrumentation in High Energy Physics held from February 15-26 and hosted by the Tata Institute of Fundamental Research (TIFR), Bombay. The scientific programme was put together by the ICFA Panel for Future Instrumentation, Innovation and Development, chaired by Tord Ekelof (Uppsala). The programme included lectures and topical seminars covering a wide range of detector subjects. In small groups, students got acquainted with modern detector technologies in the laboratory sessions, using experimental setups assembled in various institutes world-wide and shipped to Bombay for the School. The techniques covered included multiwire proportional chambers for detection of particles and photons, gaseous detectors for UV photons and X-ray imaging, the study of charge drift in silicon detectors, measurement of the muon lifetime using liquid scintillators, tracking using scintillating fibres, and electronics for sensitive detectors. The India School was attended by around 80 students from 20 countries; 34 came from Indian universities. It was the fifth in this series, previous Schools having been at Trieste (1987, 1989 and 1991) organized by the ICFA Panel and hosted and sponsored by the International Centre for Theoretical Physics, and in 1990, organized at Rio de Janeiro in collaboration with the Centro Brasileiro de Pesquisas Fisicas. The School was jointly directed by Suresh Tonwar (TIFR), Fabio Sauli (CERN) and Marleigh Sheaff (University of Wisconsin), and sponsored by TIFR and DAE (India), CERN (Switzerland), ICTP and INFN (Italy), British Council and RAL (UK), NSF and DOE (USA), KEK (Japan), IPP (Canada) and DESY (Germany)

    To improve the quantitative description of precipitation processes in climate models, the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Climate Research Facility has been collecting observations of the drop size spectra of rain events since early in 2006. Impact disdrometers were the initial choice due to their reliability, ease of maintenance, and relatively low cost. Each of the two units deployed was accompanied by a nearby tipping bucket. In 2010, the tipping buckets were replaced by weighing buckets rain gauges. Five video disdrometers were subsequently purchased and are described in ARM’s VDIS Handbook.1 As of April 2011, three of the weighing bucket instruments were deployed, one was to travel with the second ARM Mobile Facility, and the fifth was a spare. Two of the video disdrometers were deployed, a third was to be deployed later in the spring of 2011, one was to travel with the second ARM Mobile Facility, and the last was a spare. Detailed descriptions of impact disdrometers and their datastreams are provided in this document.

    Horner, Andrew B.; Beauchamp, James W.

    During the 1970s and 1980s, before synthesizers based on direct sampling of musical sounds became popular, replicating musical instruments using frequency modulation (FM) or wavetable synthesis was one of the “holy grails” of music synthesis. Synthesizers such as the Yamaha DX7 allowed users great flexibility in mixing and matching sounds, but were notoriously difficult to coerce into producing sounds like those of a given instrument. Instrument design wizards practiced the mysteries of FM instrument design.

    Work carried out in 1996 in the Department of Radiation Detectors concentrated on three subjects: (i) Semiconductor Detectors (ii) X-ray Tube Generators (iii) Material Modification Using Ion and Plasma Beams. The Departamental objectives are: a search for new types of detectors, adapting modern technologies (especially of industrial microelectronics) to detector manufacturing, producing unique detectors tailored for physics experiments, manufacturing standard detectors for radiation measuring instruments. These objectives were accomplished in 1996 by: research on unique detectors for nuclear physics (e.g. a spherical set of particle detectors silicon ball), detectors for particle identification), development of technology of high-resistivity silicon detectors HRSi (grant proposal), development of thermoelectric cooling systems (grant proposal), research on p-i-n photodiode-based personal dosimeters, study of applicability of industrial planar technology in producing detectors, manufacturing detectors developed in previous years, re-generating and servicing customer detectors of various origin. The Department conducts research on the design and technology involved in producing X-ray generators based on X-ray tubes of special construction. Various tube models and their power supplies were developed. Some work has also been devoted to the detection and dosimetry of X-rays. X-ray tube generators are applied to non-destructive testing and are components of analytical systems such as: X-ray fluorescence chemical composition analysis, gauges of layer thickness and composition stress measurements, on-line control of processes, others where an X-ray tube may replace a radio-isotope source. In 1996, the Department: reviewed the domestic demand for X-ray generators, developed an X-ray generator for diagnosis of ostheroporosis of human limbs, prepared a grant proposal for the development of a new instrument for radiotherapy, the so-called needle-like X-ray tube.

    Low energy microscopy is treated as the low energy limit of electron microscopy as a whole in all its basic branches, i.e., the emission, transmission and scanning microscopy. The instrumental and methodological aspects are briefly discussed. They include the interaction of electrons with a solid, the contrast formation mechanisms, the instrumentation problems, and actual progress achieved in all three types of microscopy from the point of view of lowering the energy of electrons, impacting or leaving the specimen, down to the low energy range below 5 keV and the very low energy range below 50 eV.

    Full text: The Department's continuing interest is centered on the mechanisms of mutagenesis and DNA repair. Part of the studies concerns the effects of the interdependence of mutator and antimutator genes on the response of E. coli cells to various mutagens. The phenomenon of mutation frequency decline (MFD) was studied and recently distinct response of this system to UV light and to alkylating agents was shown. Studies on the isfA gene, which is involved in the regulation of the SOS response, including its precise localization on the bacterial chromosome, were continued. Also, studies on the mechanism of DNA replication-independent mutagenesis in lambda phage were continued. Halogen light mutagenesis and the role of the hem gene in the near UV and UVA irradiation mutagenesis were investigated. New experimental approaches were adapted to study adaptive mutations. Another part of the studies was focused on the relation between the structure of DNA bases adducts and their coding and mutagenic properties, as well as their properties as substrates for DNA repair enzymes. These studies include instrumental methods, such as NMR, MS, HPLC and GC/MS, to investigate structure and the kinetics of formation and excision of adducts, and organic chemistry methods to synthesize adducts. The coding and mutagenic properties of several oxidized and alkylated bases (including imidazole-ring opened purines) were determined by employing in vitro enzymatic and phage/bacteria systems. The sites of reaction of chloroacetaldehyde, a metabolite of carcinogenic vinyl chloride, with a fragment of human p53 gene, were studied using the method of polymerase fingerprint analysis. Ethenoadducts, the products of the reaction of chloroacetaldehyde with adenine and cytosine, and also products of solvolytic degradation of ethenoadenine, were studied as substrates of various DNA glycosylases. Several purine and pyrimidine derivatives were synthesized and tested as inhibitors of DNA glycosylases

    The Cloud Condensation Nuclei Counter—CCN (Figure 1) is a U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility instrument for measuring the concentration of aerosol particles that can act as cloud condensation nuclei [1, 2]. The CCN draws the sample aerosol through a column with thermodynamically unstable supersaturated water vapor that can condense onto aerosol particles. Particles that are activated, i.e., grown larger in this process, are counted (and sized) by an Optical Particle Counter (OPC). Thus, activated ambient aerosol particle number concentration as a function of supersaturation is measured. Models CCN-100 and CCN-200 differ only in the number of humidifier columns and related subsystems: CCN-100 has one column and CCN-200 has two columns along with dual flow systems and electronics.

    The aim of this thesis was to develop two new infrared astronomical instruments, the University of New South Wales Infrared Fabry-Perot spectrometer (UNSWIRF) and the Infrared Camera of the University of New South Wales (IRC-UNSW), and modify an optics for one existing astronomical instrument, the Automated Patrol Telescope (APT). The optical modification of the APT overcame the problem of a curved focal plane and increased the flat field of view from 0.9° to 5°, twice as big as our original goal. In addition, glass filters of 5-mm thickness can now be inserted into its f/1 beam without image blurring. The simulation, analysis and redesign of the optical system are presented in detail. Several results from testing on the sky are presented as well. UNSWIRF is a near-infrared tunable imaging spectrometer used in conjunction with IRIS on the Anglo-Australian Telescope (AAT). It is the first successful infrared Fabry-Perot spectrometer developed in Australia. Its many challenging features, such as the wide field of view, high spectral and spatial resolution and wide tunable range have been rewarded by exciting observing results obtained during commissioning in February 1996. A major contribution of this thesis has been in the calibration of the Fabry-Perot etalon. IRC-UNSW is a new near-infrared camera with a tunable Fabry-Perot for infrared astronomy. IRC-UNSW is designed for use on the 4-m Anglo-Australian Telescope (AAT) and the 2.3-m telescope of the Australian National University. The camera optics use a novel design of three off-axis mirrors, allowing correction of the off-axis aberrations in the telescopes themselves, and producing images with FWHM blur circles of 10 mm or less over a wide field of view without chromatic affects. An external Fabry- Perot etalon is used as a high-resolution spectrometer. In its opto-mechanical design, the performance of the camera with respect to thermal effects, stray light, misalignment and manufacturing errors have been

    (full text) Work carried out in 1997 in the Department of Radiation Detectors concentrated on three subjects: (i) Semiconductor Detectors (ii) X-ray Tube Generators (iii) Material Modification using Ion and Plasma Beams. Semiconductor detectors: Semiconductor detectors of ionizing radiation are among the basic tools utilized in such fields of research and industry as nuclear physics, high energy physics, medical (oncology) radiotherapy, radiological protection, environmental monitoring, energy dispersive X-ray fluorescence non-destructive analysis of chemical composition, nuclear power industry. The Department all objectives are: - search for new types of detectors, - adapting modern technologies (especially of industrial microelectronics) to detector manufacturing, - producing unique detectors tailored for physics experiments, - manufacturing standard detectors for radiation measuring instruments, - scientific development of the staff. These 1997 objectives were accomplished particularly by: - research on unique detectors for nuclear physics (e.g. transmission type Si(Li) detectors with extremely thin entrance and exit window), - development of technology of high-resistivity (HRSi) silicon detectors and thermoelectric cooling systems (KBN grant), - study of the applicability of industrial planar technology in producing detectors, - manufacturing detectors developed in previous years, re-generating and servicing customer detectors of various origin. In accomplishing of the above, the Department cooperated with interested groups of physicists from our Institute (P-I and P-II Departments), Warsaw University, Warsaw Heavy Ion Laboratory and with some technology Institutes based in Warsaw (ITME, ITE). Some detectors and services have been delivered to customers on a commercial basis.

    A robust identification of the instrument currently used by the surgeon is crucial for the automatic modeling and analysis of surgical procedures. Various approaches for intra-operative surgical instrument identification have been presented, mostly based on radio-frequency identification (RFID) or endoscopic video analysis. A novel approach is to identify the instruments on the instrument table of the scrub nurse with a combination of video and weight information. In a previous article, we successfully followed this approach and applied it to multiple instances of an ear, nose and throat (ENT) procedure and the surgical tray used therein. In this article, we present a metric for the suitability of the instruments of a surgical tray for identification by video and weight analysis and apply it to twelve trays of four different surgical domains (abdominal surgery, neurosurgery, orthopedics and urology). The used trays were digitized at the central sterile services department of the hospital. The results illustrate that surgical trays differ in their suitability for the approach. In general, additional weight information can significantly contribute to the successful identification of surgical instruments. Additionally, for ten different surgical instruments, ten exemplars of each instrument were tested for their weight differences. The samples indicate high weight variability in instruments with identical brand and model number. The results present a new metric for approaches aiming towards intra-operative surgical instrument detection and imply consequences for algorithms exploiting video and weight information for identification purposes.

    Two special calorimeters are foreseen for the instrumentation of the very forward region of the ILC detector, a luminometer designed to measure the rate of low angle Bhabha scattering events with a precision better than 10 -3 and a low polar angle calorimeter, adjacent to the beam-pipe. The latter will be hit by a large amount of beamstrahlung remnants. The amount and shape of these depositions will allow a fast luminosity estimate and the determination of beam parameters. The sensors of this calorimeter must be radiation hard. Both devices will improve the hermeticity of the detector in the search for new particles. Finely segmented and very compact calorimeters will match the requirements. Due to the high occupancy fast front-end electronics is needed. The design of the calorimeters developed and optimised with Monte Carlo simulations is presented. Sensors and readout electronics ASICs have been designed and prototypes are available. Results on the performance of these major components are summarised.

    The requirements and characteristics of radiation measurement instruments vary according to the circumstances under which they are used (field, area, laboratory conditions) and according to their purpose (radiation survey, personal monitoring, use in emergencies, or alpha, beta or gamma counting). In fact, radiation measurement instruments are so varied that only an overview has been presented here. Groups of instruments for these and other conditions or uses are presented in tabular form together with their operational characteristics and requirements. While examples of calibrations, efficiencies and variability of all the listed instruments are not given in this chapter, these parameters are illustrated for the most important types of gamma and beta survey instruments, in some cases with a specific instrument used as an example. Some of the important parameters that need to be considered for laboratory counting of alpha and beta particles are presented. Charts for determination of optimum sample and background counting times, errors and statistics are given

    In Denmark emergency departments are newly established and still in a process of devising their procedures and technology support. Electronic whiteboards are a means of supporting clinicians in creating and maintaining the overview necessary to provide quality treatment of patients. The concrete...... meaning of the notion of overview is, however, fussy. To explore the notion of overview and how it might be affected by whiteboards, we conducted a survey at two emergency departments and, for reasons of comparison, a pediatric department. Our results indicate that respondents consider the information...... on their dry-erase whiteboards important to their overview and that they are positive toward the introduction of electronic whiteboards. At the emergency departments, the phy-sicians’ and nurses’ overall perception of their overview correlates with different subcomponents of overview, suggesting differences...

This report summarizes studies of the appropriateness of the instrumentation specified for use in Project W-211. The instruments were evaluated in a test loop with simulated slurries that covered the range of properties specified in the functional design criteria. The results of the study indicate that the compact nature of the baseline Project W-211 loop does not result in reduced instrumental accuracy resulting from poor flow profile development. Of the baseline instrumentation, the Micromotion densimeter, the Moore Industries thermocouple, the Fischer and Porter magnetic flow meter, and the Red Valve Pressure transducer meet the desired instrumental accuracy. An alternate magnetic flow meter (Yokagawa) gave nearly identical results as the baseline fischer and Porter. The Micromotion flow meter did not meet the desired instrument accuracy but could potentially be calibrated so that it would meet the criteria. The Nametre on-line viscometer did not meet the desired instrumental accuracy and is not recommended as a quantitative instrument although it does provide qualitative information. The recommended minimum set of instrumentation necessary to ensure the slurry meets the Project W-058 acceptance criteria is the Micromotion mass flow meter and delta pressure cells

    Deficiencies exist in both the performance and the quality of health physics instruments. Recognizing the implications of such deficiencies for the protection of workers and the public, in the early 1980s the DOE and the NRC encouraged the development of a performance standard and established a program to test a series of instruments against criteria in the standard. The purpose of the testing was to establish the practicality of the criteria in the standard, to determine the performance of a cross section of available instruments, and to establish a testing capability. Over 100 instruments were tested, resulting in a practical standard and an understanding of the deficiencies in available instruments. In parallel with the instrument testing, a value-impact study clearly established the benefits of implementing a formal testing program. An ad hoc committee also met several times to establish recommendations for the voluntary implementation of a testing program based on the studies and the performance standard. For several reasons, a formal program did not materialize. Ongoing tests and studies have supported the development of specific instruments and have helped specific clients understand the performance of their instruments. The purpose of this presentation is to trace the history of instrument testing to date and suggest the benefits of a centralized formal program.

    The Strontium Iodide Radiation Instrumentation (SIRI) is designed to space-qualify new gamma-ray detector technology for space-based astrophysical and defense applications. This new technology offers improved energy resolution, lower power consumption and reduced size compared to similar systems. The SIRI instrument consists of a single europiumdoped strontium iodide (SrI2:Eu) scintillation detector. The crystal has an energy resolution of 3% at 662 keV compared to the 6.5% of traditional sodium iodide and was developed for terrestrial-based weapons of mass destruction (WMD) detection. SIRI's objective is to study the internal activation of the SrI2:Eu material and measure the performance of the silicon photomultiplier (SiPM) readouts over a 1-year mission. The combined detector and readout measure the gammaray spectrum over the energy range of 0.04 - 4 MeV. The SIRI mission payoff is a space-qualified compact, highsensitivity gamma-ray spectrometer with improved energy resolution relative to previous sensors. Scientific applications in solar physics and astrophysics include solar flares, Gamma Ray Bursts, novae, supernovae, and the synthesis of the elements. Department of Defense (DoD) and security applications are also possible. Construction of the SIRI instrument has been completed, and it is currently awaiting integration onto the spacecraft. The expected launch date is May 2018 onboard STPSat-5. This work discusses the objectives, design details and the STPSat-5 mission concept of operations of the SIRI spectrometer.

    The technology of modifying surfaces of practical-use materials by means of continuous and pulsed energy and particle beams has been intensely studied for more than 20 years. In some fields it is presently utilized on a wide scale in industry. Continuous or pulsed ion and plasma beams play a significant role among various approaches used in this area. The research carried by Department P-IX is centered around the use of two own ion implantation machines (ion implanters) of different kind and several world-wide unique sources of high-intensity intense plasma pulses, utilized jointly with Department P-V. The Department cooperates closely with Forschungszentrum Rossendorf (FZR, Dresden, Germany) in the field of ion-beam-based analytical techniques and the use of unique ion implantation facilities. The main objectives of the Department are: search for new ways of modifying surface properties of solid materials by means of continuous or pulsed ion and plasma beams and implementation of ion implantation technique in national industries as a method of improving the lifetime of machine parts and tools utilized in industry. In 2006 these objectives were accomplished in many ways, particularly by research on: formation of superconducting MgB 2 phases, electrical conductivity in metallic nano-layers produced in oxide insulators (Al 2 O 3 ) by ion implantation, ion implantation as a method of improving mechanical properties of stainless steels without degrading their corrosion resistance, ion implantation/plasma treatment of ceramics aimed at improving their wettability in ceramic-metal joints, methods of controlling wear of ceramic-polymer pairs used in bio-medical applications.

    This book presents the physical principles, the performances, limits and domains of use of the main nuclear radiation detectors. The detection and characterization of a radioactive or nuclear material is possible using its characteristic, spontaneous or induced radiation emissions. Up to the end of the 1960's, the use of nuclear radiation detection and measurement methods remained limited. With the development of the nuclear industry, the main nations in concern have established control, monitoring and follow up procedures for nuclear materials and nuclear facilities as well. Nuclear detection, measurement and instrumentation started to develop and has been permanently improved and adapted thereafter. Today, nuclear instrumentation and measurement is a scientific, technical and technological subject on its own. This book presents, first, a recall of the radiation/matter interaction mechanisms with their basic physical principles. Basic and essential elements of statistics applied to radiation measurements are presented as well. Essential notions about electronic data acquisition and processing chains are explained. Then, some examples of application and use of radiation detectors are given, in particular in the domain of instrumentation and control systems for PWR type reactors. A series of exercises is proposed at the end of each chapter. (J.S.)

    Emergency departments use has been constantly increasing over the world. Overcrowding is defined as a situation which compromises patient safety because of delayed cares. This situation is often reached. Emergency departments have to continuously improve their organization to be able to ensure the same quality of care to a higher number of patients. Thus a good organization is essential: it doesn't always avoid overcrowding. The rest of the hospital has to be involved in this process to ensure efficiency. We examine the various interventions and procedures that can be found in medical literature for improving patients flow and management in emergency departments.

    The last twenty years have seen major advances in the electronics industry. Perhaps the most significant aspect of these advances has been the significant role that electronic equipment plays in almost all product markets. Even though electronic equipment is used in a broad base of applications, many future applications have yet to be conceived. This versatility of electron­ ics has been brought about primarily by the significant advances that have been made in integrated circuit technology. The electronic product user is rarely aware of the integrated circuits within the equipment. However, the user is often very aware of the size, weight, mod­ ularity, maintainability, aesthetics, and human interface features of the product. In fact, these are aspects of the products that often are instrumental in deter­ mining its success or failure in the marketplace. Optimizing these and other product features is the primary role of Electronic Equipment Packaging Technology. As the electronics industry continues to pr...

    DEVICE FABRICATION LABORATORY DEVELOPMENT The space allocated for this laboratory was shell space that required an upfit in order to accommodate nano-fabrication equipment in a quasi-clean room environment. This construction project (cost $279,736) met the non-federal cost share requirement of $250,000 for this award. The central element of the fabrication laboratory is a new $400,000+ stand-alone system, funded by other sources, for fabricating and characterizing photovoltaic devices, in a state-of-the-art nanofabrication environment. This congressionally directed project also included the purchase of an energy dispersive x-ray analysis (EDX) detector for a pre-existing transmission electron microscope (TEM). This detector allows elemental analysis and elemental mapping of materials used to fabricate solar energy devices which is a key priority for our research center. TASK 2: SOLAR ENERGY SPECTROSCOPY LABORATORY DEVELOPMENT (INSTRUMENTATION) This laboratory provides access to modern spectroscopy and photolysis instrumentation for characterizing devices, materials and components on time scales ranging from femtoseconds to seconds and for elucidating mechanisms. The goals of this congressionally directed project included the purchase and installation of spectroscopy and photolysis instrumentation that would substantially and meaningfully enhance the capabilities of this laboratory. Some changes were made to the list of equipment proposed in the original budget. These changes did not represent a change in scope, approach or aims of this project. All of the capabilities and experiments represented in the original budget were maintained. The outcome of this Congressionally Directed Project has been the development of world-class fabrication and spectroscopy user facilities for solar fuels research at UNC-CH. This award has provided a significant augmentation of our pre-existing instrumentation capabilities which were funded by earlier UNC SERC projects, including the Energy

    A number of new, ultra-low-powered radiation instruments have recently been developed at Los Alamos. Among these are two instruments which use a novel power source to eliminate costly batteries. The newly developed gamma detecting radiac, nicknamed the Firefly, and the alpha particle detecting instrument, called the Simple Cordless Alpha Monitor, both use recent advances in miniaturization and powersaving electronics to yield devices which are small, rugged, and very power-frugal. The two instruments consume so little power that the need for batteries to run them is eliminated. They are, instead, powered by a charged capacitor which will operate the instruments for an hour or more. Use of a capacitor as a power source eliminates many problems commonly associated with battery-operated instruments, such as having to open the case to change batteries, battery storage life, availability of batteries in the field, and some savings in weight. Both line power and mechanical sources are used to charge the storage capacitors which power the instruments

The distributed instrumentation system contains sensors, legacy hardware, TCP/IP protocol converter, TCP/IP network Ethernet, Database Server, Web/Application Server and Client PCs. As part of the proposed work, Tiny Internet Interface (TINI, TBM390: Dallas Semiconductor) has been deployed as TCP/IP stack, and java programming language as software tools. A feature supported by Java, that is particularly relevant to the distributed system is its applet. An applet is a java class that can be downloaded from the web server and can be run in a context application such as web browser or an applet viewer. TINI has been installed as TCP/IP stack, as it is the best suited embedded system with java programming language and it has been uniquely designed for communicating over One Wire Devices (OWD) over network. Here we will discuss the hardware and software aspects of TINI with OWD for the present system. (author)

    In the past decade, great technological progress has been made in telemaintenance of mainframe and mini computers. As hardware technology is now available at an acceptable cost, computer aided trouble-shooting can be adapted to laboratory instrumentation in order to significantly improve repair time, avoid instrument downtime by taking advantage of predictive methods, and provide general diagnostic assistance. Depending on the size of the instrument, the telemaintenance facility can be dedicated to a single instrument or alternatively a telemaintenance server can manage multiple distributed small instruments through a Local Area Network. As complex failures can occur, the local diagnosis capabilities may be exceeded and automatic dialing for connection to computerized Remote Maintenance Centers is needed. The main advantages of such a centre, as compared to local diagnosis systems, are the increased access to more information and experience of failures from instrument installations, and consequently the provision of training data updates for Artificial Neural Networks and Knowledge Based Systems in general. When an abnormal situation is detected or anticipated by a diagnosis module, an automatic alert is given to the user, local diagnosis is activated, and for simple solutions, instructions are given to the operator. In the last resort, a human expert can be alerted who, with remote control tools, can attend to the failures. For both local and remote trouble-shooting, the data provided by the instrument and connected workstation is of paramount importance for the efficiency and accuracy of the diagnosis. Equally, the importance of standardization of telemaintenance communication protocols is addressed.

    1986-01-01

    The IAEA training courses in the field of nuclear electronics heavily rely upon practical work in the laboratory. Accordingly, the IAEA has produced and published the Nuclear Electronics Laboratory Manual (TECDOC 309) where the experience on organizing the efficient practical training in nuclear electronics was compiled. The present publication is focused on the theoretical understanding of basic electronic circuits and is of particular importance to the attendees of the IAEA training course. The present publication does not copy any available book on nuclear electronics and instrumentation. On purpose, it does not describe the elementary electronics circuits as applied in nuclear instruments; they can be found in books. It starts the nuclear electronics study on the instruments level, continues to describe the technology and circuitries on the board level, and only in some exceptional cases investigates the circuits on the components level. It is believed that such an approach better reflects the advanced status of nuclear electronics and the philosophy of the modern design of nuclear instruments. For illustration, and wherever it appeared useful, some commercial instruments are described and analyzed

  19. Digital management of an electron microscope unit

    International Nuclear Information System (INIS)

    Elea, N.; Dickson, M.; Munroe, P.

    2002-01-01

    Full text: Electron microscope units, especially those such as ours, which operate as a central infrastructural facility are increasingly asked to provide more service, over more instruments with decreasing, or limited, financial resources. We believe that staff time is best used performing electron microscopy, assisting users and maintaining instrumentation rather than in the pursuit of red tape. One solution to this problem has been the creation of a control system which performs all routine acts of data management, such as the archiving and accessing of digital data, providing access to bookings, and most importantly in the era of user pays services, logging time and billing users. The system we have created, developed and expanded allows the users themselves to access our server through any web-browser and make their own bookings or access and manipulate their data. Users themselves must log on to a microscope through swipecard readers before it can be used and log-off after use. Their time is logged precisely and an exquisitely fair user pays systems can be operated by transferring logged usage time to spreadsheets to calculate charges. Furthermore, this system acts as a method of user authentication and can be used to bar incompetent or unauthorised users. The system has recently been upgraded to increase its utility to include sensors that monitor the electron microscope operating environment, such as magnetic field, room temperature, water flow etc, so that if these parameters depart significantly from optimum levels electron microscope unit staff may be alerted. In this presentation the structure of our system will be described and the advantages and disadvantages of such a system will be discussed.

    Rybicki, K.

    1999-01-01

    Full text: 1998 was the first full calendar year of the formal existence of our Department which evolved from the Laboratory of Electronic Particle Detectors (originally called Laboratory of Filmless Detectors) founded in 1972. The department is involved in two running experiments (DELPHI at CERN and H1 at DESY) and in one experiment (BELLE at KEK) which will start data taking in 1999. In addition, three department members work for the ATLAS collaboration at CERN. Since the DELPHI experiment will soon be terminated, we are considering future enterprises. One possibility is the TESLA project at DESY (our technicians have been working for several years on the construction and testing of superconducting cavities for the project). Another possibility is the LHC-b experiment at CERN. The main results of work done in 1998 are covered in reports on research. Here we mention only a few highlights. In the DELPHI experiment the cross section for the process e + e - → W + W - has been measured for several energies. Data registered so far allowed determination of the W mass with the accuracy comparable to the Tevatron results. An important role in these measurements has been played by the sophisticated silicon detector to which the Cracow group brought a substantial contribution. The analysis of more H1 data has weakened the indication for an excess of very high Q 2 events reported in 1997. Thus the paper on isolated leptons with very high transverse momenta was formulated even more carefully. In these and in several other studies the topological second level trigger designed, installed and improved by the Cracow-Orsay collaboration was very important. In the BELLE experiment the HALNY system has been designed and installed by our people. The system allows fast readout and filtering of signals from the Silicon Vertex Detector which is crucial for the experiment. One should also mention high-quality carbon-carbon composites produced in collaboration with the High Energy

    The ESTEEM consortium of electron microscopy laboratories for materials science and solid-state physics has been created as an EU-supported delocalized infrastructure to bring together the major electron microscopy centres in Europe. Its main objectives were to develop networking, to offer trans-national access to these centres with specialized and complementary techniques and skills and to upgrade in close collaboration different technical and methodological aspects such as tomography, spectroscopy, holography, detectors, and specimen holders. These efforts were aimed to strengthen the position of European microscopy and to generate new technologies potentially of high relevance in many domains identified as strategic. Following the success of the first program, ESTEEM has been conducted again in 2012 for 4 more years with an enlarged set of partners. (authors)

  7. Nuclear instrument technician training

    International Nuclear Information System (INIS)

    Wollesen, E.S.

    1991-01-01

    This paper reports on Nuclear Instrument Technician (NIT) training that has developed at an accelerated rate over the past three decades. During the 1960's commercial nuclear power plants were in their infancy. For that reason, there is little wonder that NIT training had little structure and little creditability. NIT training, in many early plants, was little more than On-The Job Training (OJT). The seventies brought changes in Instrumentation and Controls as well as emphasis on the requirements for more in depth training and documentation. As in the seventies, the eighties saw not only changes in technologies but tighter requirements, standardized training and the development of accredited Nuclear Instrument Training; thus the conclusion: Nuclear Instrument Training Isn't What It Used To Be

  8. Development and testing of a fast digital electronic system for ion identification and spectroscopy; Etude et realisation d'une chaine d'instrumentation numerique rapide pour l'identification des ions

    Energy Technology Data Exchange (ETDEWEB)

    Legou, Th

    2002-02-01

    This report deals with a fast digital electronic system developed for ion identification and spectroscopy. The system, called IRIS, has been conceived for the super heavy element research program: FUSION. In order to observe a super heavy element, the energy of the compound nucleus implanted in a silicon detector must be measured, and the alpha decay also registered. The associated electronics must therefore handle a very wide range of energies and also exhibit a small recovery time after the implantation of the compound nucleus. IRIS is connected to the output of a charge preamplifier. It digitizes the signal and then executes two digital signal processes: the first to detect the particle, and the second to determine the energy deposited in the silicon detector. The use of programmed processing allows for the adjustment of the digital processing parameters, as well as a choice of other digital signal processing procedures, depending the application. After having explained why a conventional electronic system cannot be used for the detection of super-heavy ions, IRIS' structure is detailed and a number of digital signal processing procedures are studied and tested.

    Thermography is an imaging method using the instrument to detect infrared rays emitted from the body surface, and to plot them as a distribution diagram of the temperature information. Therefore, a thermographic instrument can be assumed to measure the skin temperature of the diseased region. Such an instrument is a useful device for noninvasive and objective assessment of various diseases. Examination using a thermographic instrument can assess the autonomic dysfunction by measuring the skin blood flow involved with the sympathetic innervation. Thermography is useful in assisting the determination of the therapeutic effect. However, autonomic dysfunction should be confirmed correctly with the assessment of thermatome that shows abnormal thermal distribution in the region of the disease. Thermography should make noticeable the difference between the body temperature of abnormal and normal sites, and show the alteration of temperature. Monitoring using thermography is useful to determine the effect of sympathetic nerve block. If a thermographic instrument is used, it is important that examiners should understand the function of the instrument, as well as its advantages and disadvantages.

    Department of Training and Consulting is regularly serving secondary schools' pupils and teachers, university students and the public. As usual we have been visited by about 7000 visitors, mainly students from secondary schools in Poland. The Department is constantly developing experiments which can be conducted by students of secondary schools and universities, as well as by professionals. At the moment there are about 20 experiments available for the guests of the Department. They cover measurements of the lifetimes, elements of radioprotection, absorption of radiation in various materials, excitation of fluorescence radiation, influence of magnetic field on beta radiation as well as electrons emitted from typical electron gun, Compton scattering and elements of gamma spectroscopy, search for radioactive pollutions etc. In addition the Department was very active during Science Picnic in May and Science Festival in September, when the Department proposed organisation of a '' Day with Radioactivity ''. '' The Day '' consisted of a number of public lectures and demonstrations. In addition two evenings were dedicated to a public debate on energy sources and energy demands and supply in next 50-100 years. One should also mention organisation and leading of the professional course for accelerators' operators, as well as starting a new university course on '' Nuclear Energy and Its Use '' (Cardinal Stefan Wyszynski University, Warsaw).

  7. Hybrid microcircuits for nuclear instrumentation

    International Nuclear Information System (INIS)

    Kulkarni, R.G.

    2005-01-01

    Hybrid microcircuits (HMCs) have distinct advantages over their rival products like printed circuit boards (PCBs) and integrated circuits (ICs), and are able to survive the onslaught of Moore's law, by retaining the niche market for themselves. The ASIC development cost is normally huge and when the volumes are small (less than ten thousand or so), the prohibitively high unit cost deters the potential customers. However the HMCs can be developed at a small fraction of an ASIC development cost and thus they are attractive when the volumes are small, as in the case of professional electronics industries like defense, broadcast, or instrumentation industries. The hybrid microcircuit (HMC) technology can involve one of the two processes: thick-film and thin- film. Broadly the thick-film process consists of printing and firing of, conductor and resistor pastes, on an Alumina substrate. The thin-film process consists of photo lithographic etching of, conductor and resistor patterns, on a metal/resistor sputtered high purity Alumina substrate. The active devices, either in die-form or in surface-mount form, are attached to the thick-film or the thin-film substrate. The passive devices like chip inductors and chip capacitors are also attached to the substrate. This paper discusses in detail the thick-film and the thin-film processes and their relative merits and demerits. The associated qualification and screening procedures followed to provide reliable HMCs to the customer are described. The existing HMC facilities and the product range available in Bharat Electronics including the HMCs developed for nuclear instrumentation are presented. (author)

  9. Reactor instrumentation and control

    International Nuclear Information System (INIS)

    Wach, D.; Beraha, D.

    1980-01-01

    The methods for measuring radiation are shortly reviewed. The instrumentation for neutron flux measurement is classified into out-of-core and in-core instrumentation. The out-of-core instrumentation monitors the operational range from the subcritical reactor to full power. This large range is covered by several measurement channels which derive their signals from counter tubes and ionization chambers. The in-core instrumentation provides more detailed information on the power distribution in the core. The self-powered neutron detectors and the aeroball system in PWR reactors are discussed. Temperature and pressure measurement devices are briefly discussed. The different methods for leak detection are described. In concluding the plant instrumentation part some new monitoring systems and analysis methods are presented: early failure detection methods by noise analysis, acoustic monitoring and vibration monitoring. The presentation of the control starts from an qualitative assessment of the reactor dynamics. The chosen control strategy leads to the definition of the part-load diagram, which provides the set-points for the different control systems. The tasks and the functions of these control systems are described. In additiion to the control, a number of limiting systems is employed to keep the reactor in a safe operating region. Finally, an outlook is given on future developments in control, concerning mainly the increased application of process computers. (orig./RW)

    In the last few years a much greater emphasis has been placed upon understanding, controlling and monitoring the environmental effects of the advancing technologies. This has resulted in rapid advances in techniques for environmental monitoring. To aid the concerned scientist in keeping abreast of these developments, the Lawrence Berkeley Laboratory publishes a collection of volumes entitled Instrumentation for Environmental Monitoring. Separated into four volumes covering four media, AIR, WATER, RADIATION, and BIOMEDICAL, they provide a source book for three types of material: (1) Monitoring Rationale. They describe the characteristics, forms, and effects of a wide variety of pollutants and the means of controlling them. Federal regulations are explained and summarized. (2) Analytical Techniques. Methods of determining specific pollutants are described with special emphasis on the principles that form the basis of instrumental methods. (3) Commercial Instrumentation. The features of most commercially available instrumentation used for the determination and monitoring of each pollutant are presented in a manner that facilitates instrumental comparisons. Examples of the types of material in the volumes and the use of the volumes are presented

    Mayya, Y.S.

    2012-01-01

    The key motivations for advances in instrumentation in Nuclear industry always are - improved plant availability and safety with reduced cost. The time tested design principles applicable to safety systems in Nuclear power plants guide these developments: simplicity, diversity, independence, defence-in-depth and fail-safety. Nuclear instruments are primarily made up of detectors/sensors and processing electronics. Today's instruments leverage the latest advancements in material science, sensors, architectures, processors, computation and development platforms, networks, software, diagnostics and HMl technologies to achieve the above objectives. Nuclear plants are heavily instrumented: a wide variety of instruments are deployed not only for the safe and reliable operation of the plant itself but also for the monitoring of health and safety of personnel. This applies to all nuclear installations including research and power reactors, fuel reprocessing plants, fuel fabrication facilities, heavy water plants etc. In addition to the above, it has now become necessary for these plants to have instruments for monitoring movement of Special nuclear materials. Historically, the nuclear industry has been slower in embracing new technologies due to the rigorous process of verification and validation involved for licensing. As newer technologies emerge, they also impinge on regulatory framework, principles and practices as has been happening over the previous decades as computers and software based systems made gradual inroads in to the safety island. Electronics Corporation of India came into being with the mandate of meeting all the instrumentation requirements of the Atomic Energy Program of the country. This not only includes the instrumentation for safe operation of nuclear power reactors and allied facilities but also for the related basic and nuclear science research and development activities. Since its inception, ECIL has been involved in the development, production

    The Department of Energy (DOE) designated the Advanced Test Reactor (ATR) as a National Scientific User Facility (NSUF) in April 2007 to support U.S. leadership in nuclear science and technology. By attracting new research users - universities, laboratories, and industry - the ATR will support basic and applied nuclear research and development, further advancing the nation's energy security needs. A key component of the ATR NSUF effort is to prove new in-pile instrumentation techniques that are capable of providing real-time measurements of key parameters during irradiation. To address this need, an assessment of instrumentation available and under-development at other test reactors has been completed. Based on this review, recommendations are made with respect to what instrumentation is needed at the ATR and a strategy has been developed for obtaining these sensors. Progress toward implementing this strategy is reported in this document. It is anticipated that this report will be updated on an annual basis.

    The use of video equipment as instrumentation has been increasing steadily over the past decade. An indication of this trend can be found close to home: notice how rapidly the number of television (TV) displays has grown at our technical exhibits. It is this exhibited equipment and other equipment like it which form the subject of this summary. We will limit our discussions to readily available hardware (and a little software) and leave reports of the leading edge development work to other issues of this journal. We hope, in this manner, to present useful information to those who need to apply video to their instrumen-tation problems now. Along the way we will occasionally indicate what equipment might soon result from current research, but our clear emphasis will be on the state of the art of accessible instrumentation video.

    When the Federal Government decided on a 25% reduction of CO 2 emissions till 2005 in 1990 the necessity resulted that an instrument has to be developed for the analysis and assessment of the ecological, economic and energetic impact of different reduction strategies. The development task was awarded by the BMFT to the Research Centre Juelich in cooperation with well-known institutions of energy system research. The total instrument is scheduled to be finished by the end of 1994. For the decentral use of the instrument by a wide specialist public the developed models and data banks which are equipped with a user-friendly surface are suited for larger PCs (486, 16 MB RAM/500-1000 MB ROM).

    2016-04-01

    The Aethalometer is an instrument that provides a real-time readout of the concentration of “Black” or “Elemental” carbon aerosol particles (BC or E) in an air stream (see Figure 1 and Figure 2). It is a self-contained instrument that measures the rate of change of optical transmission through a spot on a filter where aerosol is being continuously collected and uses the information to calculate the concentration of optically absorbing material in the sampled air stream. The instrument measures the transmitted light intensities through the “sensing” portion of the filter, on which the aerosol spot is being collected, and a “reference” portion of the filter as a check on the stability of the optical source. A mass flowmeter monitors the sample air flow rate. The data from these three measurements is used to determine the mean BC content of the air stream.

    Full Text Available The rules laid down by Romanian Capital Market Law and the regulations put in force for its implementation apply to issuers of financial instruments admitted to trading on the regulated market established in Romania. But the issuers remain companies incorporated under Company Law of 1990. Such dual regulations need increased attention in order to observe the legal status of the issuers/companies and financial instruments/shares. Romanian legislator has chosen to implement in Capital Market Law special rules regarding the administration of the issuers of financial instruments, not only rules regarding admitting and maintaining to a regulated market. Thus issuers are, in Romanian Law perspective, special company that should comply special rule regarding board of administration and general shareholders meeting.

    1984-12-01

    A demonstration of the short-term storage and subsequent retrieval of spent nuclear fuel assemblies was successfully completed at the US Department of Energy's Nevada Test Site. Nearly 1000 instruments were deployed to monitor the temperature of rock, air, and metallic components of the test; displacements and stress changes within the rock mass; radiation dosage to personnel and to the rock; thermal energy input; characteristics of the ventilation airstream; and the operational status of the test. Careful selection, installation, calibration, and maintenance of these instruments ensured the acquisition of about 15.3 x 10 6 high-quality data points. With few exceptions, the performance and reliability of the instrumentation and associated data acquisition system (DAS) were within specified acceptable limits. Details of the performance and reliability of the instrumentation are discussed in this report. 42 figs., 32 tabs

    2000-01-01

    Full text: Our Department evolved from the Laboratory of Electronic Particle Detectors (originally called the Laboratory of Filmless Detectors) founded in 1972. The department is involved in three running experiments (DELPHI at CERN, H1 at DESY and BELLE at KEK). In 1999, we joined the LHC-b experiment at CERN. In addition, three department members work part-time for the ATLAS collaboration at CERN and our technicians have been working for several years on the construction and testing of superconducting cavities for the TESLA project. This arrangement provides a neat equilibrium between data producing experiments (2000 is the last year of the DELPHI running) and future projects. The main results of work done in 1999 are covered in reports on research. Here we mention only a few highlights. The first runs of the BELLE experiment have shown that the apparatus and the software can cope with the luminosity of 6 x 10 31 cm -2 s -1 presently available at KEK-B. The DELPHI experiment measured the parameters of the W boson with an accuracy comparable to that of the Tevatron. This allowed still more precise tests of the Standard Model. Some of them, like the determination of the cross sections for the production of Z 0 Z 0 and q(anti)q pairs, were actually done in Cracow. A novel study of p-p and Λ-Λ correlations performed in Cracow showed that the size of the particle emitting region decreases with particle mass. The H1 experiment published the first results on open beauty production at HERA. The cross section seems to be higher than the predictions of Quantum Chromodynamics in the Next-to-Leading Order. The work on a prototype detector for the LHC-b has just started in Cracow. One should also mention high-quality carbon-carbon composites designed and produced in collaboration with the High Energy Physics Detector Construction Group. For the first time, there were as many as 47 papers (fulfilling the highest KBN standard) published in a single year, the members of our

    As the sensory system for an accelerator, the beam instrumentation provides a tremendous amount of diagnostic information. Access to this information can vary from periodic spot checks by operators to high bandwidth data acquisition during studies. In this paper, example applications will illustrate the requirements on interfaces between the control system and the instrumentation hardware. A survey of the major accelerator facilities will identify the most popular interface standards. The impact of developments such as isochronous protocols and embedded digital signal processing will also be discussed

    2011-01-01

    A spectroelectrochemical instrument has been developed for measuring the total organic carbon (TOC) content of an aqueous solution. Measurements of TOC are frequently performed in environmental, clinical, and industrial settings. Until now, techniques for performing such measurements have included, various ly, the use of hazardous reagents, ultraviolet light, or ovens, to promote reactions in which the carbon contents are oxidized. The instrument now being developed is intended to be a safer, more economical means of oxidizing organic carbon and determining the TOC levels of aqueous solutions and for providing a low power/mass unit for use in planetary missions.

    A fire at a nuclear power plant (NPP) has the potential to damage structures, systems, and components important to safety, if not promptly detected and suppressed. At Browns Ferry Nuclear Power Plant on March 22, 1975, a fire in the reactor building damaged electrical power and control systems. Damage to instrumentation cables impeded the function of both normal and standby reactor coolant systems, and degraded the operators’ plant monitoring capability. This event resulted in additional NRC involvement with utilities to ensure that NPPs are properly protected from fire as intended by the NRC principle design criteria (i.e., general design criteria 3, Fire Protection). Current guidance and methods for both deterministic and performance based approaches typically make conservative (bounding) assumptions regarding the fire-induced failure modes of instrumentation cables and those failure modes effects on component and system response. Numerous fire testing programs have been conducted in the past to evaluate the failure modes and effects of electrical cables exposed to severe thermal conditions. However, that testing has primarily focused on control circuits with only a limited number of tests performed on instrumentation circuits. In 2001, the Nuclear Energy Institute (NEI) and the Electric Power Research Institute (EPRI) conducted a series of cable fire tests designed to address specific aspects of the cable failure and circuit fault issues of concern1. The NRC was invited to observe and participate in that program. The NRC sponsored Sandia National Laboratories to support this participation, whom among other things, added a 4-20 mA instrumentation circuit and instrumentation cabling to six of the tests. Although limited, one insight drawn from those instrumentation circuits tests was that the failure characteristics appeared to depend on the cable insulation material. The results showed that for thermoset insulated cables, the instrument reading tended to drift

    2000-08-01

    The area of test and measurement is changing rapidly because of the recent developments in software and hardware. The test and measurement systems are increasingly becoming PC based. Most of these PC based systems use graphical programming language to design test and measurement modules called virtual instruments (Vis). These Vis provide visual representation of dat or models, and make understanding of abstract concepts and algorithms easier. This allows users to express their ideas in a concise manner. One such virtual instruments package is LabVIEW from National Instruments Corporation at Austin, Texas. This software package is one of the first graphical programming products and is currently used in number of academic institutions, industries, Department of Defense graphical programming products and is currently sued in number of academic institutions, industries, Department of Defense, Department of Energy, and National Aeronautics and Space Administration for various test, measurement, and control applications. LabVIEW has an extensive built-in VI library that can be used to design and develop solutions for different applications. Besides using the built-in VI library that can be used to design and develop solutions for different applications. Besides using the built-in VI modules in LabVIEW, the user can design new VI modules easily. This paper discusses the use of LabVIEW to design and develop digital signal processing VI modules such as Fourier Analysis and Windowing. Instructors can use these modules to teach some of the signal processing concepts effectively.

    1994-08-01

    A miniaturized multichannel scaler instrument has been developed to address size and operational constraints for data acquisition in a portable laser-induced luminescence system. The multichannel scaling (MCS) function is implemented as a programmable application specific integrated circuit (ASIC) with standard interfaces for control and data acquisition. The instrument is microcontroller-based with sufficient computing power for data manipulation and algorithmic processing. The unit includes electronics for laser control and amplification and pulse height discrimination of PMT pulses. Modification of the instrument should allow use in nuclear, chemical, and spectroscopy-related applications including Mossbauer experiments (left bracket) 1,2 (right bracket). Interfaces are incorporated allowing both computer-controlled and stand-alone operation. Implementation of the MCS function as an ASIC and comparison with conventional implementations are discussed. Full characterization of the MCS is presented including differential non-linearity (DNL), bin dead time, and bandwidth measurements.

    2017-09-01

    Appropriate delivery of Emergency Department (ED) treatment to children with acute asthma requires clinician assessment of acute asthma severity. Various clinical scoring instruments exist to standardize assessment of acute asthma severity in the ED, but their selection remains arbitrary due to few published direct comparisons of their properties. Our objective was to test the feasibility of directly comparing properties of multiple scoring instruments in a pediatric ED. Using a novel approach supported by a composite data collection form, clinicians categorized elements of five scoring instruments before and after initial treatment for 48 patients 2-18 years of age with acute asthma seen at the ED of a tertiary care pediatric hospital ED from August to December 2014. Scoring instruments were compared for inter-rater reliability between clinician types and their ability to predict hospitalization. Inter-rater reliability between clinician types was not different between instruments at any point and was lower (weighted kappa range 0.21-0.55) than values reported elsewhere. Predictive ability of most instruments for hospitalization was higher after treatment than before treatment (p < 0.05) and may vary between instruments after treatment (p = 0.054). We demonstrate the feasibility of comparing multiple clinical scoring instruments simultaneously in ED clinical practice. Scoring instruments had higher predictive ability for hospitalization after treatment than before treatment and may differ in their predictive ability after initial treatment. Definitive conclusions about the best instrument or meaningful comparison between instruments will require a study with a larger sample size.

    2014-07-01

    Full Text Available To carry out this project an electronic multichannel system of electrochemical measurement or multipotenciostat was developed. It is based on the cyclic voltammetry measurement technique, controlled by a computer that monitors, by means of an electronic circuit, both the voltage generated from the Pc and supplied to an electrolytic cell, and the current that flows through the electrodes of it. To design the application software and the user interface, Virtual Instrumentation was used. On the other hand, to perform the communication between the multipotenciostat circuit and the designed software, the National Instruments NI9263 and NI9203 acquisition modules were used. The system was tested on a substance with a known REDOX property, as well as to discriminate and classify some samples of coffee.

    Two special calorimeters are foreseen for the instrumentation of the very forward region of the ILC detector, a luminometer designed to measure the rate of low angle Bhabha scattering events with a precision better than 10{sup -3} and a low polar angle calorimeter, adjacent to the beam-pipe. The latter will be hit by a large amount of beamstrahlung remnants. The amount and shape of these depositions will allow a fast luminosity estimate and the determination of beam parameters. The sensors of this calorimeter must be radiation hard. Both devices will improve the hermeticity of the detector in the search for new particles. Finely segmented and very compact calorimeters will match the requirements. Due to the high occupancy fast front-end electronics is needed. The design of the calorimeters developed and optimised with Monte Carlo simulations is presented. Sensors and readout electronics ASICs have been designed and prototypes are available. Results on the performance of these major components are summarised. (orig.)

    Science.gov (United States)

    Grant, William B.; Browell, Edward V.

    1990-01-01

    Lidar, an acronym for light detection and ranging, represents a class of instruments that utilize lasers to send probe beams into the atmosphere or onto the surface of the Earth and detect the backscattered return in order to measure properties of the atmosphere or surface. The associated technology has matured to the point where two lidar facilities, Geodynamics Laser Ranging System (GLRS), and Laser Atmospheric Wind Sensor (LAWS) were accepted for Phase 2 studies for Eos. A third lidar facility Laser Atmospheric Sounder and Altimeter (LASA), with the lidar experiment EAGLE (Eos Atmospheric Global Lidar Experiment) was proposed for Eos. The generic lidar system has a number of components. They include controlling electronics, laser transmitters, collimating optics, a receiving telescope, spectral filters, detectors, signal chain electronics, and a data system. Lidar systems that measure atmospheric constituents or meteorological parameters record the signal versus time as the beam propagates through the atmosphere. The backscatter arises from molecular (Rayleigh) and aerosol (Mie) scattering, while attenuation arises from molecular and aerosol scattering and absorption. Lidar systems that measure distance to the Earth's surface or retroreflectors in a ranging mode record signals with high temporal resolution over a short time period. The overall characteristics and measurements objectives of the three lidar systems proposed for Eos are given.

    Energy Technology Data Exchange (ETDEWEB)

    Uin, J. [Brookhaven National Lab. (BNL), Upton, NY (United States)

    2016-03-01

    The Integrating Nephelometer (Figure 1) is an instrument that measures aerosol light scattering. It measures aerosol optical scattering properties by detecting (with a wide angular integration – from 7 to 170°) the light scattered by the aerosol and subtracting the light scattered by the carrier gas, the instrument walls and the background noise in the detector (zeroing). Zeroing is typically performed for 5 minutes every day at midnight UTC. The scattered light is split into red (700 nm), green (550 nm), and blue (450 nm) wavelengths and captured by three photomultiplier tubes. The instrument can measure total scatter as well as backscatter only (from 90 to 170°) (Heintzenberg and Charlson 1996; Anderson et al. 1996; Anderson and Ogren 1998; TSI 3563 2015) At ARM (Atmospheric Radiation Measurement), two identical Nephelometers are usually run in series with a sample relative humidity (RH) conditioner between them. This is possible because Nephelometer sampling is non-destructive and the sample can be passed on to another instrument. The sample RH conditioner scans through multiple RH values in cycles, treating the sample. This kind of setup allows to study how aerosol particles’ light scattering properties are affected by humidification (Anderson et al. 1996). For historical reasons, the two Nephelometers in this setup are labeled “wet” and “dry”, with the “dry” Nephelometer usually being the one before the conditioner and sampling ambient air (the names are switched for the MAOS measurement site due to the high RH of the ambient air).

    An auto-ranging AC resistance measuring instrument for remote measurement of the resistance of an electrical device or circuit connected to the instrument includes a signal generator which generates an AC excitation signal for application to a load, including the device and the transmission line, a monitoring circuit which provides a digitally encoded signal representing the voltage across the load, and a microprocessor which operates under program control to provide an auto-ranging function by which range resistance is connected in circuit with the load to limit the load voltage to an acceptable range for the instrument, and an auto-compensating function by which compensating capacitance is connected in shunt with the range resistance to compensate for the effects of line capacitance. After the auto-ranging and auto-compensation functions are complete, the microprocessor calculates the resistance of the load from the selected range resistance, the excitation signal, and the load voltage signal, and displays of the measured resistance on a digital display of the instrument. 8 figs.

    Knuth, Kevin H.; Erner, Philip M.; Frasso, Scott

    2007-11-01

    Remote science operations require automated systems that can both act and react with minimal human intervention. One such vision is that of an intelligent instrument that collects data in an automated fashion, and based on what it learns, decides which new measurements to take. This innovation implements experimental design and unites it with data analysis in such a way that it completes the cycle of learning. This cycle is the basis of the Scientific Method. The three basic steps of this cycle are hypothesis generation, inquiry, and inference. Hypothesis generation is implemented by artificially supplying the instrument with a parameterized set of possible hypotheses that might be used to describe the physical system. The act of inquiry is handled by an inquiry engine that relies on Bayesian adaptive exploration where the optimal experiment is chosen as the one which maximizes the expected information gain. The inference engine is implemented using the nested sampling algorithm, which provides the inquiry engine with a set of posterior samples from which the expected information gain can be estimated. With these computational structures in place, the instrument will refine its hypotheses, and repeat the learning cycle by taking measurements until the system under study is described within a pre-specified tolerance. We will demonstrate our first attempts toward achieving this goal with an intelligent instrument constructed using the LEGO MINDSTORMS NXT robotics platform.

    1983-01-01

    Reliable instrumentation will be needed to evaluate the characteristics of proposed high-level nuclear waste repository sites and to monitor the performance of selected sites during the operational period and into repository closure. A study has been done to assess the reliability of instruments used in Department of Energy (DOE) waste repository related experiments and in other similar geological applications. The study included experiences with geotechnical, hydrological, geochemical, environmental, and radiological instrumentation and associated data acquisition equipment. Though this paper includes some findings on the reliability of instruments in each of these categories, the emphasis is on experiences with geotechnical instrumentation in hostile repository-type environments. We review the failure modes, rates, and mechanisms, along with manufacturers modifications and design changes to enhance and improve instrument performance; and include recommendations on areas where further improvements are needed

    2009-11-01

    Emergency department (ED) crowding and ambulance diversion has been an increasingly significant national problem for more than a decade. More than 90% of hospital ED directors reported overcrowding as a problem resulting in patients in hallways, full occupancy of ED beds, and long waits, occurring several times a week. Overcrowding has many other potential detrimental effects including diversion of ambulances, frustration for patients and ED personnel, lesser patient satisfaction, and most importantly, greater risk for poor outcomes. This article gives a basic blueprint for successfully making hospital-wide changes using principles of operational management. It briefly covers the causes, significance, and dangers of overcrowding, and then focuses primarily on specific solutions.

    Netherlands Hydrological Modeling Instrument A decision support system for water basin management. J.C. Hoogewoud , W.J. de Lange ,A. Veldhuizen , G. Prinsen , The Netherlands Hydrological modeling Instrument (NHI) is the center point of a framework of models, to coherently model the hydrological system and the multitude of functions it supports. Dutch hydrological institutes Deltares, Alterra, Netherlands Environmental Assessment Agency, RWS Waterdienst, STOWA and Vewin are cooperating in enhancing the NHI for adequate decision support. The instrument is used by three different ministries involved in national water policy matters, for instance the WFD, drought management, manure policy and climate change issues. The basis of the modeling instrument is a state-of-the-art on-line coupling of the groundwater system (MODFLOW), the unsaturated zone (metaSWAP) and the surface water system (MOZART-DM). It brings together hydro(geo)logical processes from the column to the basin scale, ranging from 250x250m plots to the river Rhine and includes salt water flow. The NHI is validated with an eight year run (1998-2006) with dry and wet periods. For this run different parts of the hydrology have been compared with measurements. For instance, water demands in dry periods (e.g. for irrigation), discharges at outlets, groundwater levels and evaporation. A validation alone is not enough to get support from stakeholders. Involvement from stakeholders in the modeling process is needed. There fore to gain sufficient support and trust in the instrument on different (policy) levels a couple of actions have been taken: 1. a transparent evaluation of modeling-results has been set up 2. an extensive program is running to cooperate with regional waterboards and suppliers of drinking water in improving the NHI 3. sharing (hydrological) data via newly setup Modeling Database for local and national models 4.

    The Nuclear Electronics Laboratory Manual is a joint product of several electronics experts who have been associated with IAEA activity in this field for many years. The manual does not include experiments of a basic nature, such as characteristics of different active electronics components. It starts by introducing small electronics blocks, employing one or more active components. The most demanding exercises instruct a student in the design and construction of complete circuits, as used in commercial nuclear instruments. It is expected that a student who completes all the experiments in the manual should be in a position to design nuclear electronics units and also to understand the functions of advanced commercial instruments which need to be repaired or maintained. The future tasks of nuclear electronics engineers will be increasingly oriented towards designing and building the interfaces between a nuclear experiment and a computer. The manual pays tribute to this development by introducing a number of experiments which illustrate the principles and the technology of interfacing

    The scanning electron microscope equipped with an x-ray spectrometer is a versatile instrument which has many uses in the investigation of crime and preparation of scientific evidence for the courts. Major applications include microscopy and analysis of very small fragments of paint, glass and other materials which may link an individual with a scene of crime, identification of firearms residues and examination of questioned documents. Although simultaneous observation and chemical analysis of the sample is the most important feature of the instrument, other modes of operation such as cathodoluminescence spectrometry, backscattered electron imaging and direct x-ray excitation are also exploited. Marks on two bullets or cartridge cases can be compared directly by sequential scanning with a single beam or electronic linkage of two instruments. Particles of primer residue deposited on the skin and clothing when a gun is fired can be collected on adhesive tape and identified by their morphology and elemental composition. It is also possible to differentiate between the primer residues of different types of ammunition. Bullets may be identified from the small fragments left behind as they pass through the body tissues. In the examination of questioned documents the scanning electron microscope is used to establish the order in which two intersecting ink lines were written and to detect traces of chemical markers added to the security inks on official documents.

    The Ultraviolet and Visible Imagers and Spectrographic Imagers (UVISI) instrument is a complex of nine sensor units (five spectrographic imagers and four imagers) and multiple processors that will provide detailed images and spectra of targets for the Midcourse Space Experiment mission. Imaging and spectroscopy each cover the range from 110 nm (far ultraviolet) to 900 nm (near infrared). UVISI is intended to investigate a multitude of celestial, atmospheric, and point sources over its planned 4-year lifetime. At 104 W and 211 kg, it is not only the largest free-flying instrument ever built at APL, but is also larger than 47 of the 55 APL-built spacecraft and more complex than many of them. This article discusses the specifications of UVISI and its hardware and software features. It also attempts to give the reader a sense of the design trade-offs made during UVISI development that resulted in its present configuration.

The laminar structure of the associated counter tube, using only a few, simple plastic parts and a highly elastic counter wire, makes it possible to use the simplest manufacturing techniques. The service life of the counter tube construction, which is completely and permanently sealed and filled with gas, is expected to be more than 12 years. The described counter tube can be adapted in optimal fashion to the available space in a pocket instrument if it is used in combination with a specialized high-voltage generator which is low in interference voltage and with a pulse evaluation circuit having a means of compensating for interference voltage

    A field-portable gas chromatograph-mass spectrometer (Hapsite ER system) was evaluated for the detection of chemical warfare agents (CWAs) in the vapor phase. The system consisted of Tri-Bed concentrator gas sampler (trapping time: 3s(-1)min), a nonpolar low thermal-mass capillary gas chromatography column capable of raising temperatures up to 200°C, a hydrophobic membrane-interfaced electron ionization quadrupole mass spectrometer evacuated by a non-evaporative getter pump for data acquisition, and a personal computer for data analysis. Sample vapors containing as little as 22μg sarin (GB), 100μg soman (GD), 210μg tabun (GA), 55μg cyclohexylsarin (GF), 4.8μg sulfur mustard, 390μg nitrogen mustard 1, 140μg of nitrogen mustard 2, 130μg nitrogen mustard 3, 120μg of 2-chloroacetophenone and 990μg of chloropicrin per cubic meter could be confirmed after Tri-Bed micro-concentration (for 1min) and automated AMDIS search within 12min. Using manual deconvolution by background subtraction of neighboring regions on the extracted ion chromatograms, the above-mentioned CWAs could be confirmed at lower concentration levels. The memory effects were also examined and we found that blister agents showed significantly more carry-over than nerve agents. Gasoline vapor was found to interfere with the detection of GB and GD, raising the concentration limits for confirmation in the presence of gasoline by both AMDIS search and manual deconvolution; however, GA and GF were not subject to interference by gasoline. Lewisite 1, and o-chlorobenzylidene malononitrile could also be confirmed by gas chromatography, but it was hard to quantify them. Vapors of phosgene, chlorine, and cyanogen chloride could be confirmed by direct mass spectrometric detection at concentration levels higher than 2, 140, and 10mg/m(3) respectively, by bypassing the micro-concentration trap and gas chromatographic separation.

    Caused by legal reform initiatives there is a continuous need to increase effectiveness and efficiency in hospitals and surgeries, and thus to improve processes.Consequently the successful management of radiological departments and surgeries requires suitable structures and optimization processes to make optimization in the fields of medical quality, service quality and efficiency possible.In future in the DRG System it is necessary that the organisation of processes must focus on the whole clinical treatment of the patients (Clinical Pathways). Therefore the functions of controlling must be more established and adjusted. On the basis of select Controlling instruments like budgeting, performance indicators, process optimization, staff controlling and benchmarking the target-based and efficient control of radiological surgeries and departments is shown. © Georg Thieme Verlag KG Stuttgart · New York.
