    . Careful consideration and planning is therefore required. After a brief recall of the ISPs' objectives, this document provides guidelines to be followed during the different phases of an ISP. Two phases are considered. The first one consists in proposing and selecting an ISP, the second one consists in performing an ISP. This revised document was prepared under the Leadership of J.-C. Micaelli (IRSN). It was reviewed and endorsed in September 2003 by the Working Group on the Analysis and Management of Accidents (GAMA), GAMA performed in 2003 a survey on updating CSNI Report No. 17, 'CSNI Standard Problem Procedures', first published in 1977, last updated in 1989. The objective of this activity was to collect proposals regarding the improvement of ISP efficiency with respect to their objectives and the improvement of the quality of the procedures document. Eleven series of questions were asked in the survey, related to: - General structure of the procedures document; - ISP objectives; - Six phases: ISP proposal, ISP specification, ISP results reporting, Preparation of the preliminary data comparison and interpretation report, Post-ISP analysis, Preparation of the final comparison and interpretation report; - Updating of the procedures; - Support to be provided by the participants

    This manual contains the Radiation Control Standards'' and Radiation Control Procedures'' at Hanford Operations which have been established to provide the necessary control radiation exposures within Irradiation Processing Department. Provision is also made for including, in the form of Bulletins'', other radiological information of general interest to IPD personnel. The purpose of the standards is to establish firm radiological limits within which the Irradiation Processing Department will operate, and to outline our radiation control program in sufficient detail to insure uniform and consistent application throughout all IPD facilities. Radiation Control Procedures are intended to prescribe the best method of accomplishing an objective within the limitations of the Radiation Control Standards. A procedure may be changed at any time provided the suggested changes is generally agreeable to management involved, and is consistent with department policies and the Radiation Control Standards.

  3. Authentication: A Standard Problem or a Problem of Standards?

    Full Text Available Reproducibility and transparency in biomedical sciences have been called into question, and scientists have been found wanting as a result. Putting aside deliberate fraud, there is evidence that a major contributor to lack of reproducibility is insufficient quality assurance of reagents used in preclinical research. Cell lines are widely used in biomedical research to understand fundamental biological processes and disease states, yet most researchers do not perform a simple, affordable test to authenticate these key resources. Here, we provide a synopsis of the problems we face and how standards can contribute to an achievable solution.

    2013-01-01

    After Fukushima Accident (March 11, 2011), the Atomic Energy Society of Japan (AESJ) started to develop the standard of Tsunami Probabilistic Risk Assessment (PRA) for nuclear power plants in May 2011. As Japan is one of the countries with frequent earthquakes, a great deal of efforts has been made in the field of seismic research since the early stage. To our regret, the PRA procedures guide for tsunami has not yet been developed although the importance is held in mind of the PRA community. Accordingly, AESJ established a standard to specify the standardized procedure for tsunami PRA considering the results of investigation into the concept, the requirements that should have and the concrete methods regarding tsunami PRA referring the opinions of experts in the associated fields in December 2011 (AESJ-SC-RK004:2011).

    Tamra Bhasma (incinerated copper) is one of the main weapons in the archery of Ayurvedic practitioners. Though several methods of preparation of Tamra Bhasma (TB) are found in Rasashastra classics, several difficulties occur during the preparation of a good-quality Bhasma. In this study, TB was prepared and analyzed to develop the standard manufacturing procedure. Each unit operative procedure was considered as an independent processing and an attempt was made to validate each procedure. Wire used for the purpose of electrical earthing was taken for the preparation of Bhasma. Procedures of Shodhana, Marana, and Amritikarana were followed as per the classical references. Specific temperature pattern was adopted for Puta in the electrical muffle furnace. From 500 g of Tamra, 483.4 g of black colored TB was obtained after subjecting to three Putas. Final product was detected to be cupric sulfide in X-ray diffraction. In particle size distribution analysis 10% of the material was below the size of 2 μm, while in inductive coupled plasma - atomic absorption spectrometry 58.56 wt% copper and 22.48 wt% of sulfur were found present in the final product along with the elements such as arsenic, lead, zinc, mercury, and manganese in traces.

  13. Dependability of technical items: Problems of standardization

    Science.gov (United States)

    Fedotova, G. A.; Voropai, N. I.; Kovalev, G. F.

    2016-12-01

    This paper is concerned with problems blown up in the development of a new version of the Interstate Standard GOST 27.002 "Industrial product dependability. Terms and definitions". This Standard covers a wide range of technical items and is used in numerous regulations, specifications, standard and technical documentation. A currently available State Standard GOST 27.002-89 was introduced in 1990. Its development involved a participation of scientists and experts from different technical areas, its draft was debated in different audiences and constantly refined, so it was a high quality document. However, after 25 years of its application it's become necessary to develop a new version of the Standard that would reflect the current understanding of industrial dependability, accounting for the changes taking place in Russia in the production, management and development of various technical systems and facilities. The development of a new version of the Standard makes it possible to generalize on a terminological level the knowledge and experience in the area of reliability of technical items, accumulated over a quarter of the century in different industries and reliability research schools, to account for domestic and foreign experience of standardization. Working on the new version of the Standard, we have faced a number of issues and problems on harmonization with the International Standard IEC 60500-192, caused first of all by different approaches to the use of terms and differences in the mentalities of experts from different countries. The paper focuses on the problems related to the chapter "Maintenance, restoration and repair", which caused difficulties for the developers to harmonize term definitions both with experts and the International Standard, which is mainly related to differences between the Russian concept and practice of maintenance and repair and foreign ones.

  1. ISP-27 OECD/NEA/CSNI International Standard Problem n.27. Bethsy experiment 9.1 B. 2. cold leg break without HPSI and with delayed ultimate procedure. Comparison report. Volume 1 + 2

    International Nuclear Information System (INIS)

    1992-11-01

    This report is the final comparison report for ISP-27, a blind problem which is based on the BETHSY test 9.1b performed in december 1989 at the Nuclear Research Center in Grenoble (France). The BETHSY integral test facility is a scaled down model of a 3 loop 900 e MW FRAMATOME PWR; the overall scaling factor applied to every volume, mass flowrate and power level is close to 1/100, while elevations are 1/1 in order to preserve the gravitational heads. The cold leg break is combined with the High Pressure Injection System (HPIS) failure. In that case, the state oriented approach requires operators to start an Ultimate Procedure, which consists in fully opening the Steam Generator (SG) atmospheric dumps as soon as they are informed of the unavailability of the HPIS. The presently studied scenario assumes a delayed application of this procedure, which is started only when the core outlet temperature rises significantly higher than the saturation temperature. The BETHSY Test 9.1b addresses, besides typical problems relevant to Small Break Loss Of Coolant Accidents (SBLOCA) such as critical 2-phase flow, loop seal clearing, heat-transfer during boil-off or accumulator injection, specific aspects related to the fast depressurization (primary to secondary and structural heat transfer), uncovered core behavior when intense condensation takes place in the SG, and primary side refilling by the Low Pressure Injection System (LPIS)

    1996-09-01

    Several years ago, we noted that spectra transformed by the piecewise direct standardization (PDS) method may contain discontinuities. Having noticed that the problem was a recurring one, we studied it and recently diagnosed its source. Our investigations suggest that this problem also occurs in applications of window factor analysis, evolving factor analysis, and any other procedure that uses piecewise principal component models. In this work, we report the source of the problem and illustrate it with one example. A procedure is presented for eliminating the problem that is effective in PDS pattern recognition applications. Further work is needed to develop modified algorithms suitable for calibration applications.

  5. CSNI International standard problems (ISP): brief descriptions (1975-1997)

    International Nuclear Information System (INIS)

    1997-07-01

    Over the last twenty years (1975-1999) the NEA Committee on the Safety of Nuclear Installations (CSNI) has sponsored more than forty International Standard Problems (ISPs) in the fields of in-vessel thermal-hydraulic behaviour, fuel behaviour under accident conditions, fission product release and transport, core/concrete interactions, hydrogen distribution and mixing, containment thermal-hydraulic, and iodine behaviour in the containment. ISPs are comparative exercises in which predictions of different computer codes for a given physical problem are compared with each other or with the results of a carefully controlled experimental study. The main goal of ISP exercises is to increase confidence in the validity and accuracy of analytical tools or testing procedures which are needed in warranting the safety of nuclear installations, and to demonstrate the competence of involved institutions. ISP exercises are performed as 'open' or 'blind' problems. The main characteristics of 41 ISPs completed between 1975 and 1999, and 3 containment analysis standard problems (CASPs) are briefly presented

  6. CSNI International standard problems (ISP). Brief descriptions (1975-1999)

    International Nuclear Information System (INIS)

    2000-03-01

    Over the last twenty-five years the NEA Committee on the Safety of Nuclear Installations (CSNI) has sponsored a considerable number of international activities to promote the exchange of experience between its Member countries in the use of nuclear safety codes and testing materials. A primary goal of these activities is to increase confidence in the validity and accuracy of analytical tools or testing procedures which are needed in warranting the safety of nuclear installations, and to demonstrate the competence of involved institutions. International Standard Problems (ISPs) exercises are comparative exercises in which predictions or recalculations of a given physical problem with different best-estimate computer code are compared with each other and above all with the results of a carefully specified experimental study. ISP exercises are performed as 'open' or 'blind' problems. In an open Standard Problem exercise the results of the experiment are available to the participants before performing the calculations, while in a blind Standard Problem exercise the experimental results are locked until the calculation results are made available for comparison. The CSNI-promoted ISP activity started in the early 70's and is still underway. Parallel to other national and international programs the CSNI has sponsored over more than 25 years forty-seven International Standard Problem exercises. This program has been focused mainly on the applicability of large thermal-hydraulic code systems simulating the behaviour of nuclear coolant and containment systems, fuel behaviour under accident conditions, hydrogen distribution, core-concrete interactions and fission product release and transport. One ISP exercise was organised in connection with a seismic ultimate dynamic response test. ISP exercises have proven to be very valuable to participating countries. They have been fruitful to identify code application problems and to amplify the contacts between the experimental and

  7. Measuring and diagnosing unilateral neglect: a standardized statistical procedure.

    Science.gov (United States)

    Toraldo, Alessio; Romaniello, Cristian; Sommaruga, Paolo

    Unilateral neglect is usually investigated by adminstering stimuli (targets) in different positions, with targets being responded to by the patient (Hit) or omitted. In spite of this homogeneity of data type, neglect indices and diagnostic criteria vary considerably, causing inconsistencies in both clinical and experimental settings. We aimed at deriving a standard analysis which would apply to all tasks sharing this data form. A-priori theoretical reasoning demonstrated that the mean position of Hits in space (MPH) is an optimal index for correctly diagnosing and quantifying neglect. Crucially MPH eliminates the confounding effects of deficits that are different from neglect (non-lateral) but which decrease Hit rate. We ran a Monte Carlo study to assess MPH's (so far overlooked) statistical behavior as a function of numbers of targets and Hits. While average MPH was indeed insensitive to non-lateral deficits, MPH's variance (like that of all other neglect indices) increased dramatically with increasing non-lateral deficits. This instability would lead to alarmingly high false-positive rates (FPRs) when applying a classical diagnostic procedure that compares one patient with a control sample. We solved the problem by developing an equation that takes into account MPH instability and provides correct cut-offs and close-to-nominal FPRs, even without control subjects. We developed a computerized program which, given the raw data, yields the MPH, a z-score and a p-value. We provided a standard method that allows clinical and experimental neuropsychologists to diagnose and measure neglect in a consistent way across the vast majority of tasks.

    2002-01-01

    School principals were surveyed in rural and urban Nebraska schools to compare policies and procedures on school attendance, and to contrast the use of disciplinary procedures for attendance, violence and substance abuse. A survey was sent to a 50 percent random sample of Nebraska schools. Respondent school addresses in metropolitan statistical areas (MSA) areas were categorized as urban, and non-MSA respondents were classified as rural area schools. Of the 680 surveys mailed, 464 (68.2 percent) completed surveys were returned. Overall, 86.2 percent of respondents were from rural schools and 13.8 percent from urban schools. A list of disciplinary problems and procedures was reported for a first-time offense by rural and urban schools. Both an "occasional attendance problem" and a "chronic attendance problem" were most frequently addressed through parent contact in both urban and rural areas. For "fighting with another student," rural schools most commonly reported discipline by teacher, followed by discipline by principal and parent contact. In urban schools, discipline by principal was most common. For "using drugs other than alcohol or tobacco at school" in both areas, disciplinary procedures included parent contact and short-term suspension. A list of disciplinary problems and procedures was also reported for a second-time offense and third-time offense. For "fighting with another student," the most commonly reported procedure was discipline by principal and parent contact for a second-time offense, followed by short-term suspension and long-term suspension for a third-time offense. For "using drugs other than alcohol or tobacco at school," for a second time offense was long-term suspension and semester expulsion for a third-time offense. Principals were also asked in an open-response format, what program or procedures were currently in place to prevent violence in their school. Common responses were "conflict resolution training," followed by "the Boys Town

  14. Contribution from twenty two years of CSNI International Standard Problems

    International Nuclear Information System (INIS)

    1998-03-01

    This report provides a brief overview on the contribution of some CSNI International Standard Problems (ISPs) to nuclear reactor safety issues (41 ISPs performed over the last 22 years). This CSNI activity on ISPs has been one of the major activities of the Principal Working Group no.2 on Coolant System Behaviour. Its domain extended from thermal-hydraulics to several other accident domains following the main concerns of nuclear reactor safety, e.g., LOCA predictions fuel behaviour, operator procedures, containment thermal-hydraulics severe accidents, VVERs, etc. ISPs are providing unique material and benefits for some safety related issues. Clearly, all the technical findings and benefits provided by ISPs are still needed and contribute to advancement of nuclear safety. The report provides some overview on the general objectives of ISPs, content and types of ISPs, and technical domains covered by ISPs, followed by a synthesis of technical findings and benefits to the scientific community

  15. Comparison of perturbative and variational procedures in a relativistic problem

    International Nuclear Information System (INIS)

    Moshinsky, M.; Benet, L.; Loyola, G.; Salinas, A.

    1992-01-01

    For bound states two of the most popular approximative procedures are the perturbative and variational ones. These procedures have been extensively used and compared in ordinary quantum mechanics. The sistuation is more delicate in the relativistic case where we need not only to develop the methods appropriately, but also to separate in them the contribution of positive energy states, as those from the negative ones are not allowed by Dirac's procedure, which assumes them occupied by particles satisfying an exclusion principle. To illustrate the problems that appear we discuss in this paper the particle-antiparticle system with a Dirac oscillator interaction in a one dimensional space for each particle. We then develop the appropriate perturbative and variational procedures, compare their results, and discuss their range of validity as function of the value of the frequency ω of the Dirac oscillator.

  16. Solution procedure of dynamical contact problems with friction

    Science.gov (United States)

    Abdelhakim, Lotfi

    2017-07-01

    Dynamical contact is one of the common research topics because of its wide applications in the engineering field. The main goal of this work is to develop a time-stepping algorithm for dynamic contact problems. We propose a finite element approach for elastodynamics contact problems [1]. Sticking, sliding and frictional contact can be taken into account. Lagrange multipliers are used to enforce non-penetration condition. For the time discretization, we propose a scheme equivalent to the explicit Newmark scheme. Each time step requires solving a nonlinear problem similar to a static friction problem. The nonlinearity of the system of equation needs an iterative solution procedure based on Uzawa's algorithm [2][3]. The applicability of the algorithm is illustrated by selected sample numerical solutions to static and dynamic contact problems. Results obtained with the model have been compared and verified with results from an independent numerical method.

    2016-06-01

    Full Text Available We examined our experience and, in particular, complications associated with total hip arthroplasty in obese and morbidly obese patients. We prospectively gathered 50 patients in a matched control series including 25 obese and morbidly obese patients. All patients were operated using the direct lateral approach and standard postoperative protocols. Operating room time, complications, dislocations, blood loss, cup position and clinical parameters using the Harris Hip Score and the Western Ontario and McMaster Universities Arthritis Index results were compared. Although there were some significant differences in clinical outcomes, standard procedures yielded good overall results and an acceptable rate of complications. Details approaching this patient entity are being discussed.

    The authors show that the Schwarz alternating procedure offers a good algorithm for the numerical solution of singular perturbation problems, provided the domain decomposition is properly designed to resolve the boundary and transition layers. They give sharp estimates for the optimal position of the domain boundaries and present convergence rates of the algorithm for various second-order singular perturbation problems. The splitting of the operator is domain-dependent, and the iterative solution of each subproblem is based on a modified asymptotic expansion of the operator. They show that this asymptotic-induced method leads to a family of efficient massively parallel algorithms and report on implementation results for a turning-point problem and a combustion problem.

    Specimen collection is an integral component of clinical research. Specimens from subjects with various stages of cancers or other conditions, as well as those without disease, are critical tools in the hunt for biomarkers, predictors, or tests that will detect serious diseases earlier or more readily than currently possible. Analytic methodologies evolve quickly. Access to high-quality specimens, collected and handled in standardized ways that minimize potential bias or confounding factors, is key to the "bench to bedside" aim of translational research. It is essential that standard operating procedures, "the how" of creating the repositories, be defined prospectively when designing clinical trials. Small differences in the processing or handling of a specimen can have dramatic effects in analytical reliability and reproducibility, especially when multiplex methods are used. A representative working group, Standard Operating Procedures Internal Working Group (SOPIWG), comprised of members from across Early Detection Research Network (EDRN) was formed to develop standard operating procedures (SOPs) for various types of specimens collected and managed for our biomarker discovery and validation work. This report presents our consensus on SOPs for the collection, processing, handling, and storage of serum and plasma for biomarker discovery and validation.

    Given the high prevalence of mental health problems among prisoners, knowledge on its determinants is important. Prior cross-sectional studies suggest that procedurally just treatment within prison is a significant predictor; however, longitudinal research is lacking. The aims of this study were to examine (1) the longitudinal relationship between prisoners' perceptions of procedural justice--including fairness, respect, humanity and relationships with officers--and their mental health and (2) the moderating role of coping style in this relationship. Data were obtained from the Prison Project, a longitudinal study of adult male prisoners in the Netherlands, interviewed both 3 weeks and 3 months after their reception into pre-trial detention (N = 824). A cross-lagged structural equation model was employed to investigate associations. Prisoners who reported experiencing a higher level of procedural justice 3 weeks after their arrival in custody reported fewer mental health problems after 3 months. No evidence was found that coping style moderated this relationship. These findings suggest a causal relationship between procedural justice and psychological well-being. Fair and respectful treatment of prisoners is a predictor not only of prison order and prisoners' compliance but also of prisoners' psychological well-being. Copyright © 2013 John Wiley & Sons, Ltd.

  4. Standardization of SMP procedure and its impact on outcome

    Full Text Available Background: Cosmetic deformities can result from various types of alopecia or even post hair transplantation procedures. Patients with such deformities seek aesthetically appealing longer-lasting options. Scalp concealers are commonly used by men and women to camouflage these deformities. Scalp micropigmentation (SMP is one of the concealers recently gaining popularity. Objectives: SMP is a novel technique wherein microdot tattoos are placed in a stippling pattern to mimic hair follicles that are cut close to the scalp and various variables affecting its outcome were evaluated. Methods: Forty-five subjects were recruited for the study. The various factors affecting outcome of SMP—angle of needle against the scalp, depth of needle into the scalp, time of the needle contact in scalp, speed of the rotor, resistance of scalp, color of pigment, viscosity of dye, needle number, needle thickness, and pattern of dot placement—were systematically studied in 15 patients through clinical photographs and trichoscopy. Ideal depth of pigment deposition was assessed through histopathological examination. After using these optimum variables, standardized SMP was performed in 30 patients with hair loss (3 patients with cicatricial and 27 patients with diffuse non-cicatricial alopecia. SMP was also used to create an aesthetically denser hairline. The outcome of the procedure was evaluated using standardized global photographs. Results: The ideal parameters were established to achieve standard reproducible results. There were great patient satisfaction and acceptance of the procedure. All the patients showed moderate to great improvement after the procedure with satisfactory scalp coverage. Adverse events were transient which were seen in the form of edema and redness. Conclusion: SMP offers a non-medical, tattoo-based cosmetically appealing and effective “cover-up” that hides the unsightly conditions. The cosmetic tattoo placement creates an illusion of

    This document was developed to provide the personnel working in the Environmental Sciences Division's Toxicology Laboratory with documented methods for conducting toxicity tests. The document consists of two parts. The first part includes the standard operating procedures (SOPs) that are used by the laboratory in conducting toxicity tests. The second part includes reference procedures from the US Environmental Protection Agency document entitled Short-Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Freshwater Organisms, upon which the Toxicology Laboratory's SOPs are based. Five of the SOPs include procedures for preparing Ceriodaphnia survival and reproduction test. These SOPs include procedures for preparing Ceriodaphnia food (SOP-3), maintaining Ceriodaphnia cultures (SOP-4), conducting the toxicity test (SOP-13), analyzing the test data (SOP-13), and conducting a Ceriodaphnia reference test (SOP-15). Five additional SOPs relate specifically to the fathead minnow (Pimephales promelas) larval survival and growth test: methods for preparing fathead minnow larvae food (SOP-5), maintaining fathead minnow cultures (SOP-6), conducting the toxicity test (SOP-9), analyzing the test data (SOP-12), and conducting a fathead minnow reference test (DOP-14). The six remaining SOPs describe methods that are used with either or both tests: preparation of control/dilution water (SOP-1), washing of glassware (SOP-2), collection and handling of samples (SOP-7), preparation of samples (SOP-8), performance of chemical analyses (SOP-11), and data logging and care of technical notebooks (SOP-16).

    In 2008, the recently founded European Stroke Organisation published its guidelines for the management of ischemic stroke and transient ischemic attack. This highly cited document was translated in several languages and was updated in 2009. Since then, the European Stroke Organisation has published guidelines for the management of intracranial aneurysms and subarachnoidal hemorrhage, for the establishment of stroke units and stroke centers, and recently for the management of intracerebral hemorrhage. In recent years, the methodology for the development of guidelines has evolved significantly. To keep pace with this progress and driven by the strong determination of the European Stroke Organisation to further promote stroke management, education, and research, the European Stroke Organisation decided to delineate a detailed standard operating procedure for its guidelines. There are two important cornerstones in this standard operating procedure: The first is the implementation of the Grading of Recommendations Assessment, Development, and Evaluation methodology for the development of its Guideline Documents. The second one is the decision of the European Stroke Organisation to move from the classical model of a single Guideline Document about a major topic (e.g. management of ischemic stroke) to focused modules (i.e. subdivisions of a major topic). This will enable the European Stroke Organisation to react faster when new developments in a specific stroke field occur and update its recommendations on the related module rather swiftly; with the previous approach of a single large Guideline Document, its entire revision had to be completed before an updated publication, delaying the production of up-to-date guidelines. After discussion within the European Stroke Organisation Guidelines Committee and significant input from European Stroke Organisation members as well as methodologists and analysts, this document presents the official standard operating procedure for

    Commerically available Romanowsky blood stains are variable mixtures of thiazein dyes and brominated fluorescein derivatives with varying degrees of metallic salt contamination in a number of different solvent systems. There is a need for standardized Romanowsky stains of constant composition, which, when used in conjunction with a carefully controlled specimen preparation technique, should give consistent performance. Such a preparation system would be of great value to hematologists in general and would be essential to the validity of data obtained by the digital processing of blood cell images. It is possible to prepare standardized Romanowsky stains as mixtures of two or three dye components, namely, eosin Y, azure B and methylene blue, although azure B has only recently become commercially available at an acceptable degree of purity. The logistic problems of stain standardization are discussed.

  11. Problem Solving in Physics: Undergraduates' Framing, Procedures, and Decision Making

    Science.gov (United States)

    Modir, Bahar

    In this dissertation I will start with the broad research question of what does problem solving in upper division physics look like? My focus in this study is on students' problem solving in physics theory courses. Some mathematical formalisms are common across all physics core courses such as using the process of separation of variables, doing Taylor series, or using the orthogonality properties of mathematical functions to set terms equal to zero. However, there are slight differences in their use of these mathematical formalisms across different courses, possibly because of how students map different physical systems to these processes. Thus, my first main research question aims to answer how students perform these recurring processes across upper division physics courses. I break this broad question into three particular research questions: What knowledge pieces do students use to make connections between physics and procedural math? How do students use their knowledge pieces coherently to provide reasoning strategies in estimation problems? How do students look ahead into the problem to read the information out of the physical scenario to align their use of math in physics? Building on the previous body of the literature, I will use the theory family of Knowledge in Pieces and provide evidence to expand this theoretical foundation. I will compare my study with previous studies and provide suggestions on how to generalize these theory expansions for future use. My experimental data mostly come from video-based classroom data. Students in groups of 2-4 students solve in-class problems in quantum mechanics and electromagnetic fields 1 courses collaboratively. In addition, I will analyze clinical interviews to demonstrate how a single case study student plays an epistemic game to estimate the total energy in a hurricane. My second research question is more focused on a particular instructional context. How do students frame problem solving in quantum mechanics? I

    International Nuclear Information System (INIS)

    1994-07-01

    Between 1975 and 1994 the NEA Committee on the Safety of Nuclear Installations (CSNI) has sponsored some forty International Standard Problems (ISPs) in the fields of in-vessel thermal-hydraulic behaviour, fuel behaviour under accident conditions, fission product release and transport, core/concrete interactions, hydrogen distribution and mixing, containment thermal-hydraulics. ISPs are comparative exercises in which predictions of different computer codes for a given physical problem are compared with each other or with the results of a carefully controlled experimental study. The main goal of ISP exercises is to increase confidence in the validity and accuracy of tools which are used in assessing the safety of nuclear installations. Moreover, they enable code users to gain experience and demonstrate their competence. ISPs are performed as 'open' or 'blind' problems. In an open Standard Problem the results of the experiment are available to the participants before performing the calculations, while in a blind Standard Problem the results are locked until the calculational results are made available for comparison. Experiments selected to support ISP exercises are exceptionally well documented; they provide the framework for several code validation matrices. This report briefly describes 36 ISPs and 3 containment analysis standard problems (CASP)

    The objectives of the study are: (1) to determine the availability of dosimetry data and supporting documentation at multiple facilities; (2) to develop criteria and methods for optimally retrieving data; (3) to evaluate and document the quality and completeness of data and dosimetry programs; (4) to put dosimetry data (e.g., external, whole body counting, and bioassay data) from various facilities in a single format for epidemiologic analysis; and (5) to document all work for peer review. To achieve these objectives, a ''Dosimetry Records and Radiation Hazards Questionnaire'' was developed to send to the facilities under study. Responses to this questionnaire are used to develop data retrieval criteria and methods, and to retrieve data. Dose data are reformatted into Standard Intermediate Dosimetry Files for editing and characterization. Evaluations of dosimetry programs are performed concurrently. Results of these steps are brought together and analysis files created. Status of this work in the context of the Department of Energy 5-Rem Study is reported. The standard procedures are applicable to single- as well as multiple-facility studies

    1991-01-01

    The purpose of this document is to establish a set of minimum and optional requirements for the implementation of Control Authority (CA) organizations within and among the Agencies participating in the Consultative Committee for Space Data Systems (CCSDS). By satisfying these requirements, the resultant cooperating set of CA organizations will produce a global CA service supporting information transfer with digital data under the Standard Formatted Data Unit (SFDU) concept. This service is primarily accomplished through the registration, permanent archiving, and dissemination of metadata in the form of Metadata Objects (MDO) that assist in the interpretation of data objects received in SFDU form. This Recommendation addresses the responsibilities, services, and interface protocols for a hierarchy of CA organizations. The top level, consisting of the CCSDS Secretariat and its operational agent, is unique and primarily provides a global coordination function. The lower levels are Agency CA organizations that have primary responsibility for the registration, archiving, and dissemination of MDOs. As experience is gained and technology evolves, the CA Procedures will be extended to include enhanced services and their supporting protocols. In particular, it is anticipated that eventually CA organizations will be linked via networks on a global basis, and will provide requestors with online automated access to CA services. While this Recommendation does not preclude such operations, it also does not recommend the specific protocols to be used to ensure global compatibility of these services. These recommendations will be generated as experience is gained.

  19. Manual of Standard Operating Procedures for Veterinary Drug Residue Analysis

    International Nuclear Information System (INIS)

    2016-01-01

    Laboratories are crucial to national veterinary drug residue monitoring programmes. However, one of the main challenges laboratories encounter is obtaining access to relevant methods of analysis. Thus, in addition to training, providing technical advice and transferring technology, the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture has resolved to develop clear and practical manuals to support Member State laboratories. The Coordinated Research Project (CRP) on Development of Radiometric and Allied Analytical Methods to Strengthen Residue Control Programs for Antibiotic and Anthelmintic Veterinary Drug Residues has developed a number of analytical methods as standard operating procedures (SOPs), which are now compiled here. This publication contains SOPs on chromatographic and spectrometric techniques, as well as radioimmunoassay and associated screening techniques, for various anthelmintic and antimicrobial veterinary drug residue analysis. Some analytical method validation protocols are also included. The publication is primarily aimed at food and environmental safety laboratories involved in testing veterinary drug residues, including under organized national residue monitoring programmes. It is expected to enhance laboratory capacity building and competence through the use of radiometric and complementary tools and techniques. The publication is also relevant for applied research on residues of veterinary drugs in food and environmental samples

    2004-03-01

    Full Text Available For a modified Angoff standards setting procedure, two methods of calculating the standard error of the..judging were compared. The Central Limit Theorem (CLT method is easy to calculate and uses readily..available data. It estimates the variance of mean cut scores as a function of the variance of cut scores within..a judging group, based on the independent judgements at Stage 1 of the process. Its theoretical drawback is..that it is unable to take account of the effects of collaboration among the judges at Stages 2 and 3. The..second method, an application of equipercentile (EQP equating, relies on the selection of very large stable..candidatures and the standardisation of the raw score distributions to remove effects associated with test..difficulty. The standard error estimates were then empirically obtained from the mean cut score variation..observed over a five year period. For practical purposes, the two methods gave reasonable agreement, with..the CLT method working well for the top band, the band that attracts most public attention. For some..bands in English and Mathematics, the CLT standard error was smaller than the EQP estimate, suggesting..the CLT method be used with caution as an approximate guide only.

    2016-01-01

    This study uses the theoretical framework of domain-specific problem solving to explore the procedures students use to solve multiple-choice problems about biology concepts. We designed several multiple-choice problems and administered them on four exams. We trained students to produce written descriptions of how they solved the problem, and this allowed us to systematically investigate their problem-solving procedures. We identified a range of procedures and organized them as domain general, domain specific, or hybrid. We also identified domain-general and domain-specific errors made by students during problem solving. We found that students use domain-general and hybrid procedures more frequently when solving lower-order problems than higher-order problems, while they use domain-specific procedures more frequently when solving higher-order problems. Additionally, the more domain-specific procedures students used, the higher the likelihood that they would answer the problem correctly, up to five procedures. However, if students used just one domain-general procedure, they were as likely to answer the problem correctly as if they had used two to five domain-general procedures. Our findings provide a categorization scheme and framework for additional research on biology problem solving and suggest several important implications for researchers and instructors.

  8. The prevalence of mental health problems among users of NHS stop smoking services: effects of implementing a routine screening procedure

    Directory of Open Access Journals (Sweden)

    Ratschen Elena

    2011-08-01

    Full Text Available Abstract Background Tobacco dependence among people with mental health problems is an issue that deserves attention both from a clinical and from a public health perspective. Research suggests that Stop Smoking Services often fail to ask clients about underlying mental health problems and thus fail to put in place the treatment adaptations and liaison procedures often required to meet the needs of clients with a mental health condition who want to stop smoking. This study assesses the recording of mental health problems in a large NHS stop smoking service in England and examines the effect of implementing a short screening procedure on recording mental health conditions. Methods Treatment records from the Stop Smoking Service covering a period of 13 months were audited. The prevalence of reported mental health problems in the six month period before the implementation of the mental health screening procedure was compared with that of the six month period following implementation. The screening procedure was only implemented in the support services directly provided by the Stop Smoking Service. Comparisons were also made with third-party sections of the service where no such screening procedure was introduced. Results The prevalence of reported mental health problems among a total of n = 4999 clients rose from less than 1% before implementation of the screening procedure to nearly 12% in the period following implementation, with the change being statistically significant. No significant rise was observed over the same period in the sections of the service where no screening procedure was implemented. Conclusions The absence of standard procedures to record mental health problems among service users in many stop smoking services is currently likely to prevent the detection of co morbidity. Implementing a simple screening procedure appears suitable to increase the routine recording of mental health problems in a stop smoking service, which is an

  10. Standard Problems for CFD Validation for NGNP - Status Report

    2010-01-01

    The U.S. Department of Energy (DOE) is conducting research and development to support the resurgence of nuclear power in the United States for both electrical power generation and production of process heat required for industrial processes such as the manufacture of hydrogen for use as a fuel in automobiles. The project is called the Next Generation Nuclear Plant (NGNP) Project, which is based on a Generation IV reactor concept called the very high temperature reactor (VHTR). The VHTR will be of the prismatic or pebble bed type; the former is considered herein. The VHTR will use helium as the coolant at temperatures ranging from 250 C to perhaps 1000 C. While computational fluid dynamics (CFD) has not previously been used for the safety analysis of nuclear reactors in the United States, it is being considered for existing and future reactors. It is fully recognized that CFD simulation codes will have to be validated for flow physics reasonably close to actual fluid dynamic conditions expected in normal operational and accident situations. The ''Standard Problem'' is an experimental data set that represents an important physical phenomenon or phenomena, whose selection is based on a phenomena identification and ranking table (PIRT) for the reactor in question. It will be necessary to build a database that contains a number of standard problems for use to validate CFD and systems analysis codes for the many physical problems that will need to be analyzed. The first two standard problems that have been developed for CFD validation consider flow in the lower plenum of the VHTR and bypass flow in the prismatic core. Both involve scaled models built from quartz and designed to be installed in the INL's matched index of refraction (MIR) test facility. The MIR facility employs mineral oil as the working fluid at a constant temperature. At this temperature, the index of refraction of the mineral oil is the same as that of the quartz. This provides an advantage to the

  11. Standard physics solution to the solar neutrino problem?

    The {sup 8}B solar neutrino flux predicted by the standard solar model (SSM) is consistent within the theoretical and experimental uncertainties with that at Kamiokande. The Gallium and Chlorine solar neutrino experiments, however, seem to imply that the {sup 7}Be solar neutrino flux is strongly suppressed compared with that predicted by the SSM. If the {sup 7}Be solar neutrino flux is suppressed, still it can be due to astrophysical effects not included in the simplistic SSM. Such effects include short term fluctuations or periodic variation of the temperature in the solar core, rotational mixing of {sup 3}He in the solar core, and dense plasma effects which may strongly enhance p-capture by {sup 7}Be relative to e-capture. The new generation of solar observations which already look non stop deep into the sun, like Superkamiokande through neutrinos, and SOHO and GONG through acoustic waves, may point at the correct solution. Only Superkamiokande and/or future solar neutrino experiments, such as SNO, BOREXINO and HELLAZ, will be able to find out whether the solar neutrino problem is caused by neutrino properties beyond the minimal standard electroweak model or whether it is just a problem of the too simplistic standard solar model.

This study investigates preclinical students’ experience with standardized patients (SPs as a problem representation method compared to using video cases in PBL. Methods: A cohort of 99 second-year preclinical students from Inje University College of Medicine (IUCM responded to a Likert scale questionnaire on their learning experiences after they had experienced both video cases and SPs in PBL. The questionnaire consisted of 14 items with eight subcategories: problem identification, hypothesis generation, motivation, collaborative learning, reflective thinking, authenticity, patient-doctor communication, and attitude toward patients. Results: The results reveal that using SPs led to the preclinical students having significantly positive experiences in boosting patient-doctor communication skills; the perceived authenticity of their clinical situations; development of proper attitudes toward patients; and motivation, reflective thinking, and collaborative learning when compared to using video cases. The SPs also provided more challenges than the video cases during problem identification and hypotheses generation. Conclusion: SPs are more effective than video cases in delivering higher levels of authenticity in clinical problems for PBL. The interaction with SPs engages preclinical students in deeper thinking and discussion; growth of communication skills; development of proper attitudes toward patients; and motivation. Considering the higher cost of SPs compared with video cases, SPs could be used most advantageously during the preclinical period in the IUCM curriculum.

  5. The problem of epistemic jurisdiction in global governance: The case of sustainability standards for biofuels.

    Science.gov (United States)

    Winickoff, David E; Mondou, Matthieu

    2017-02-01

    While there is ample scholarly work on regulatory science within the state, or single-sited global institutions, there is less on its operation within complex modes of global governance that are decentered, overlapping, multi-sectorial and multi-leveled. Using a co-productionist framework, this study identifies 'epistemic jurisdiction' - the power to produce or warrant technical knowledge for a given political community, topical arena or geographical territory - as a central problem for regulatory science in complex governance. We explore these dynamics in the arena of global sustainability standards for biofuels. We select three institutional fora as sites of inquiry: the European Union's Renewable Energy Directive, the Roundtable on Sustainable Biomaterials, and the International Organization for Standardization. These cases allow us to analyze how the co-production of sustainability science responds to problems of epistemic jurisdiction in the global regulatory order. First, different problems of epistemic jurisdiction beset different standard-setting bodies, and these problems shape both the content of regulatory science and the procedures designed to make it authoritative. Second, in order to produce global regulatory science, technical bodies must manage an array of conflicting imperatives - including scientific virtue, due process and the need to recruit adoptees to perpetuate the standard. At different levels of governance, standard drafters struggle to balance loyalties to country, to company or constituency and to the larger project of internationalization. Confronted with these sometimes conflicting pressures, actors across the standards system quite self-consciously maneuver to build or retain authority for their forum through a combination of scientific adjustment and political negotiation. Third, the evidentiary demands of regulatory science in global administrative spaces are deeply affected by 1) a market for standards, in which firms and states can

    A careful renormalization group analysis of the electroweak Standard Model reveals that there is no hierarchy problem in the SM. In the broken phase a light Higgs turns out to be natural as it is self-protected and self-tuned by the Higgs mechanism. It means that the scalar Higgs needs not be protected by any extra symmetry, specifically super symmetry, in order not to be much heavier than the other SM particles which are protected by gauge- or chiral-symmetry. Thus the existence of quadratic cutoff effects in the SM cannot motivate the need for a super symmetric extensions of the SM, but in contrast plays an important role in triggering the electroweak phase transition and in shaping the Higgs potential in the early universe to drive inflation as supported by observation.

    The European transmission grid is facing an investment challenge. There is a strong call for more transmission capacity. At the same time, the investment climate is fierce and troubled by public opposition, a complex regulatory framework, etc. Many transmission capacity expansion projects are delayed or canceled. In this paper different technology options suitable for increasing transmission capacity are discussed. The aim is to provide policy-makers with information on technologies without going too much into technical details. The focus is on opportunities and limitations to implement various technological alternatives in practice, including technical solutions that go beyond constructing new connection lines. The criteria used in this technology assessment are based on the obstacles reported in the European Priority Interconnection Plan. This ensures a realistic approach based on problems encountered in real projects. Although AC overhead lines (OHL) will remain the standard solution for grid expansion, it is argued that different technology options can overcome many obstacles that OHL face. Additionally, it is illustrated that the higher investment costs for some solutions can be offset with an increased benefit, e.g. by accomplishing investments with smaller delays due to fewer obstacles encountered. - Research highlights: → Assessment of real problems encountered in transmission investments. → Comparison of transmission technologies. → Techno-economic evaluation of transmission technologies.

    ISP33 is the first OECD/NEA/CSNI standard problem related to VVER type of pressurized water reactors. The reference reactor of the PACTEL test facility, which was used to carry out the ISP33 experiment, is the VVER-440 reactor, two of which are located near the Finnish city of Loviisa. The objective of the ISP33 test was to study the natural circulation behaviour of VVER-440 reactors at different coolant inventories. Natural circulation was considered as a suitable phenomenon to focus on by the first VVER related ISP due to its importance in most accidents and transients. The behaviour of the natural circulation was expected to be different compared to Western type of PWRs as a result of the effect of horizontal steam generators and the hot leg loop seals. This ISP was conducted as a blind problem. The experiment was started at full coolant inventory. Single-phase natural circulation transported the energy from the core to the steam generators. The inventory was then reduced stepwise at about 900 s intervals draining 60 kg each time from the bottom of the downcomer. the core power was about 3.7% of the nominal value. The test was terminated after the cladding temperatures began to rise. ATHLET, CATHARE, RELAP5 (MODs 3, 2.5 and 2), RELAP4/MOD6, DINAMIKA and TECH-M4 codes were used in 21 pre- and 20 posttest calculations submitted for the ISP33.

    Full Text Available Lateral thoracotomy is a versatile approach with many variations and is currently the most widely used incision in thoracic surgery. In the current article we are presenting the muscle-sparing lateral thoracotomy in the lateral decubitus position which we consider to be the “standard” for lateral thoracotomies. Indications, surgical technique and pitfalls are described alongside our experience with thoracic drainage. Although there is no consensus regarding the name of this incision, some authors call it “axillary thoracotomy” while others call it a “modified lateral thoracotomy”, they all agree on one aspect – the importance of muscle sparing – which makes it the go-to thoracotomy for both small and large procedures involving the lung. Lateral muscle sparing thoracotomy allows for good exposure of the pulmonary hilum, fissures, apex and diaphragm. The approach is easy and quick to perform while at the same time ensuring faster postoperative recovery by sparing the latissimus dorsi muscle, better cosmetics and lower postoperative pain score when compared to the posterolateral or classical lateral thoracotomies.

The determination of historical patterns of judicial enforcement in the USSR in the 1930s and the identification of the causes of the ineffectiveness of the proceedings in this period.Methodology. The author uses historical legal method, formal legal interpretation of statutes, the method of analysis of judicial statistics.Results, scope of application. After the criminal law campaigns of the early 1930s the judg-ment in the Soviet Union was in a disturbed condition. The Soviet civil process was almost absolutely eliminated. Tens thousands materials of court cases were lost throughout the Union every year. The courts were extremely busy.The courts used accusatory approach. The petitions of the accused were almost never solved. Prisoners were not handed copies of the indictments.During the terror of the old evils of the judicial system worsened, the destruction of the judicial process began. The timeframe for completing cases increased. Almost half of criminal cases in case of complaint (appeal has been revised by the higher courts. The courts again applied the simplified procedure.At the end of the 1930s the procedural regulation of the judicial work was the duty of People's Commissariat of Justice of the USSR and of the Supreme Court of the USSR. USSR Supreme Court continued to take decisions in litigation in the plenums. The Boards of Su-preme Court examines cases influencing law of practice.The quality of judgment by the Supreme Courts of the Republics of Soviet Union in the late 1930s did not change significantly in comparison with the previous period. This was due to constant staff turnover and low level of qualification of judges. The Supreme Courts of the Republics had no Plenum, so they could influence law of practice by the rulings of of the Boards. These rulings were extremely ignorant

  1. Standardization of figures and assessment procedures for DTM verticalaccuracy

    Directory of Open Access Journals (Sweden)

    Vittorio Casella

    2015-07-01

    Full Text Available Digital Terrain Models (DTMs are widely used in many sectors. They play a key role in hydrological risk prevention, risk mitigation and numeric simulations. This paper deals with two questions: (i when it is stated that a DTM has a given vertical accuracy, is this assertion univocal? (ii when DTM vertical accuracy is assessed by means of checkpoints, does their location influence results? First, the paper illustrates that two vertical accuracy definitions are conceivable: Vertical Accuracy at the Nodes (VAN, the average vertical distance between the model and the terrain, evaluated at the DTM's nodes and Vertical Accuracy at the interpolated Points (VAP, in which the vertical distance is evaluated at the generic points. These two quantities are not coincident and, when they are calculated for the same DTM, different numeric values are reached. Unfortunately, the two quantities are often interchanged, but this is misleading. Second, the paper shows a simulated example of a DTM vertical accuracy assessment, highlighting that the checkpoints’ location plays a key role: when checkpoints coincide with the DTM nodes, VAN is estimated; when checkpoints are randomly located, VAP is estimated, instead. Third, an in-depth, theoretical characterization of the two considered quantities is performed, based on symbolic computation, and suitable standardization coefficients are proposed. Finally, our discussion has a well-defined frame: it doesn't deal with all the items of the DTM vertical accuracy budget, which would require a much longer essay, but only with one, usually called fundamental vertical accuracy.

    Problem behavior of companion animals poses a threat to caregivers, other targets of problem behavior (e.g., strangers, other nonhuman animals), and those animals engaging in problem behavior. This study examined the effects of an aggression reduction procedure (ARP) on dog problem behavior. After a baseline condition showing caregivers were unsuccessful in reducing dog aggression and the behaviors preceding aggression, caregivers were trained to implement a procedure to address dog problem behavior in relatively simple contexts. Generalization programming then was used to target caregiver plan implementation and dog problem behavior in more complex contexts. The ARP effectively reduced dog aggression for all dogs. A slight reduction and increased variability in dog precursor behavior was observed when the ARP was implemented. In addition, caregivers and experts rated the goals, procedures, and effects as acceptable. Implications of these findings are discussed.

  5. The importance of strong evaluation standards and procedures in training residents.

    Short, J P

    1993-07-01

    A strong evaluation process in a residency offers faculty an opportunity to strengthen the educational program, to help residents know what is expected of them, and to remove with minimum difficulties those residents who are not progressing satisfactorily and do not appear to be salvageable. Despite these advantages, the evaluation of residents during their training is often done poorly or not at all. The author describes the kinds of standards and procedures that constitute a sound, strong evaluation process, proposes criteria for academic probation and due process when a resident is performing unacceptably, and describes the role that the medical school administration should play in the evaluation process, one that is flexible enough to allow each program to comply and still have program-specific procedures. The author closes with statistics on how few residents are dismissed for incompetency or unacceptable behaviors, and inquires how many more might be found if strong evaluation processes were more widely used. Even so, in the attempt to evaluate residents and to foster protection from legal problems, residency program directors must keep in mind the importance of letting residents make mistakes and learn from them; a good evaluation system strikes a balance that fosters the learning process and benefits the residents, the medical school, and the community.

    2001-01-01

    Trends in the entrance skin exposures (air kerma) for standard x-ray imaging procedures are reported for the Province of Manitoba, Canada. Average annual data per procedure using standard phantoms and standard ion chambers have been recorded since 1981. For example, chest air kerma (backscatter included) has decreased from 0.14 to 0.09 mGy. Confounding factors may negate the gains unless facility quality control programs are maintained. The data were obtained for a quality assurance and regulatory compliance program. Quoting such data for risk evaluation purposes lacks rigor hence a compartment model for organ apportioning, using organ absorbed doses and weighting factors, has been applied to determine effective dose per procedure. The effective doses for the standard procedures are presented, including the value of 0.027 mSv (1999) calculated for the effective dose in PA chest imaging. (author)

    2016-03-01

    Practicing behavior analysts frequently assess and treat problem behavior as part of their ongoing job responsibilities. Effective measurement of problem behavior is critical to success in these activities because some measures of problem behavior provide more accurate and complete information about the behavior than others. However, not every measurement procedure is appropriate for every problem behavior and therapeutic circumstance. We summarize the most commonly used measurement procedures, describe the contexts for which they are most appropriate, and propose a clinical decision-making model for selecting measurement produces given certain features of the behavior and constraints of the therapeutic environment.

    Two identical reinforced concrete (RC) shear walls, which consist of web, flanges and massive top and bottom slabs, were tested up to ultimate failure under earthquake motions at the Nuclear Power Engineering Corporation`s (NUPEC) Tadotsu Engineering Laboratory, Japan. NUPEC provided the dynamic test results to the OECD (Organization for Economic Cooperation and Development), Nuclear Energy Agency (NEA) for use as an International Standard Problem (ISP). The shear walls were intended to be part of a typical reactor building. One of the major objectives of the Seismic Shear Wall ISP (SSWISP) was to evaluate various seismic analysis methods for concrete structures used for design and seismic margin assessment. It also offered a unique opportunity to assess the state-of-the-art in nonlinear dynamic analysis of reinforced concrete shear wall structures under severe earthquake loadings. As a participant of the SSWISP workshops, Brookhaven National Laboratory (BNL) performed finite element analyses under the sponsorship of the U.S. Nuclear Regulatory Commission (USNRC). Three types of analysis were performed, i.e., monotonic static (push-over), cyclic static and dynamic analyses. Additional monotonic static analyses were performed by two consultants, F. Vecchio of the University of Toronto (UT) and F. Filippou of the University of California at Berkeley (UCB). The analysis results by BNL and the consultants were presented during the second workshop in Yokohama, Japan in 1996. A total of 55 analyses were presented during the workshop by 30 participants from 11 different countries. The major findings on the presented analysis methods, as well as engineering insights regarding the applicability and reliability of the FEM codes are described in detail in this report. 16 refs., 60 figs., 16 tabs.

    Problems of environmental friendliness and energy efficiency in recent decades have become not only the most important issues of economic development of the main industrial economies, but also the basis for the processes of maintaining the security and relative stability of the global ecosystem. The article presents the results of the study of the status and trends of the development of environmental standards for the construction and maintenance of real estate in the world and particularly in Russia. Special market instruments for assessing the compliance with the quality of real estate projects under construction and modern principles of environmental friendliness and energy efficiency include voluntary building certification systems that are actively used in international practice. In Russia there is active use of the following international systems of certification: BREEAM, LEED, DGNB, HQE. Also in the Russian certification market, the national standard STO NOSTROY 2.35.4-2011 “Residential and public buildings” is being implemented, which summarizes the best international experience of the rating evaluation procedure. Comparative characteristics of the “green” standards and the principles of rating assessments of the ecological compatibility of buildings give an idea of applying these standards in Russia.

    Brensel, Robert; Brensel, Scott; Ng, Amy

    2013-01-01

    Since the New England Compounding Center disaster in 2012, the importance of following correct procedures during every phase of customized pharmacy has been a focus of governmental interest and action as well as public scrutiny. Many pharmacies rely on the rote review of standard operating procedures to ensure that staff members understand and follow protocols that ensure the safety and potency of all compounds prepared, but that approach to continuing education can be cumbersome and needlessly time-consuming. In addition, documenting and retrieving evidence of employee competence can be difficult. In this article, we describe our use of online technology to improve our methods of educating staff about the full range of standard operating procedures that must be followed in our pharmacy. The system we devised and implemented has proven to be effective, easy to update and maintain, very inexpensive, and user friendly. Its use has reduced the time previously required for a read-over review of standard operating procedures from 30 or 40 minutes to 5 or 10 minutes in weekly staff meetings, and we can now easily document and access proof of employees' comprehension of that content. It is our hope that other small compounding pharmacies will also find this system of online standard operating procedure review helpful.

    Beginning with the 2008 version of Title 24, new homes in California must comply with ANSI/ASHRAE Standard 62.2-2007 requirements for residential ventilation. Where installed, the limited data available indicate that mechanical ventilation systems do not always perform optimally or even as many codes and forecasts predict. Commissioning such systems when they are installed or during subsequent building retrofits is a step towards eliminating deficiencies and optimizing the tradeoff between energy use and acceptable IAQ. Work funded by the California Energy Commission about a decade ago at Berkeley Lab documented procedures for residential commissioning, but did not focus on ventilation systems. Since then, standards and approaches for commissioning ventilation systems have been an active area of work in Europe. This report describes our efforts to collect new literature on commissioning procedures and to identify information that can be used to support the future development of residential-ventilation-specific procedures and standards. We recommend that a standardized commissioning process and a commissioning guide for practitioners be developed, along with a combined energy and IAQ benefit assessment standard and tool, and a diagnostic guide for estimating continuous pollutant emission rates of concern in residences (including a database that lists emission test data for commercially-available labeled products).

    Full Text Available Multi-objective optimization and multiple criteria decision making problems are the process of designing the best alternative by considering the incommensurable and conflicting objectives simultaneously. One of the first interactive procedures to solve multiple criteria decision making problems is STEM method. In this paper we propose a modified interactive procedure based on STEM method by calculating the weight vector of objectives which emphasize that more important objectives be closer to ideal one. We use the AHP and TOPSIS method to find these weights and develop a multi-objective group decision making procedure. Therefore the presented method tries to increase the rate of satisfactoriness of the obtained solution. Finally, a numerical example for illustration of the new method is given to clarify the main results developed in this paper.

    The TASS/SMR(Transient And Setpoint System-integrated Modular Reactor) code is a thermal hydraulic analysis computer program developed for the safety and transient analysis of integral type pressurizer water reactor SMART(System-integrated Modular Advanced ReacTor) plant. Thus, the various models reflected the design features of SMART were implemented into the TASS/SMR code. Since the technologies used for the integral type reactor SMART are different from the existing reactors, the mathematical models of the TASS/SMR code that describe the thermal hydraulic processes, phenomena and numerical solution methods are required to be verified for the various operating transient and accident conditions of SMART. Also the reliability of the analysis results of the code need to be verified using proper experimental data. This is the basic study on the model verification of the TASS/SMR code and its applicability to the safety analysis of SMART. For this purpose, the basic equations set and several special models of TASS/SMR code are reviewed and the basic conceptual and analytical problems are selected to assess the fundamental numerical analysis capability. The selected basic problems are analyzed using TASS/SMR code and the results are evaluated in comparison with the known reference solution or pertinent physical models to assess the numerical capability of the TASS/SMR code and the reliability of the analysis results of the code. TASS/SMR code 2.0 Version used this analysis.

  16. Solving the Standard Model Problems in Softened Gravity

    CERN Document Server

    Salvio, Alberto

    2016-11-16

    The Higgs naturalness problem is solved if the growth of Einstein's gravitational interaction is softened at an energy $ \\lesssim 10^{11}\\,$GeV (softened gravity). We work here within an explicit realization where the Einstein-Hilbert Lagrangian is extended to include terms quadratic in the curvature and a non-minimal coupling with the Higgs. We show that this solution is preserved by adding three right-handed neutrinos with masses below the electroweak scale, accounting for neutrino oscillations, dark matter and the baryon asymmetry. The smallness of the right-handed neutrino masses (compared to the Planck scale) and the QCD $\\theta$-term are also shown to be natural. We prove that a possible gravitational source of CP violation cannot spoil the model, thanks to the presence of right-handed neutrinos. Starobinsky inflation can occur in this context, even if we live in a metastable vacuum.

    To develop and validate standardized criteria for assessing abortion-related incidents (adverse events, morbidities, near misses) for first-trimester aspiration abortion procedures and to demonstrate the utility of a standardized framework [the Procedural Abortion Incident Reporting & Surveillance (PAIRS) Framework] for estimating serious abortion-related adverse events. As part of a California-based study of early aspiration abortion provision conducted between 2007 and 2013, we developed and validated a standardized framework for defining and monitoring first-trimester (≤14weeks) aspiration abortion morbidity and adverse events using multiple methods: a literature review, framework criteria testing with empirical data, repeated expert reviews and data-based revisions to the framework. The final framework distinguishes incidents resulting from procedural abortion care (adverse events) from morbidity related to pregnancy, the abortion process and other nonabortion related conditions. It further classifies incidents by diagnosis (confirmatory data, etiology, risk factors), management (treatment type and location), timing (immediate or delayed), seriousness (minor or major) and outcome. Empirical validation of the framework using data from 19,673 women receiving aspiration abortions revealed almost an equal proportion of total adverse events (n=205, 1.04%) and total abortion- or pregnancy-related morbidity (n=194, 0.99%). The majority of adverse events were due to retained products of conception (0.37%), failed attempted abortion (0.15%) and postabortion infection (0.17%). Serious or major adverse events were rare (n=11, 0.06%). Distinguishing morbidity diagnoses from adverse events using a standardized, empirically tested framework confirms the very low frequency of serious adverse events related to clinic-based abortion care. The PAIRS Framework provides a useful set of tools to systematically classify and monitor abortion-related incidents for first

    Full Text Available Background: Currently, the standard protocol regarding the performance of procedures on patients receiving or having recently received isotretinoin (13-cis-retinoic acid states that the procedures should not be performed. The recommendations in standard books and drug insert require discontinuation of isotretinoin for 6 months before performing cosmetic procedures, including waxing, dermabrasion, chemical peels, laser procedures, or incisional and excisional cold-steel surgery. These recommendations have been followed for over two decades despite little evidence for the stated increased risk of scarring. Objective: The Association of Cutaneous Surgeons (I constituted a task force to review the evidence and to recommend consensus guidelines regarding the safety of skin procedures, including resurfacing, energy-device treatments, and dermatosurgical procedures in patients with concurrent or recent isotretinoin administration. Materials and Methods: Data were extracted from the literature through a PubMed search using the keywords “isotretinoin,” “safety,” “scarring,” “keloids,” “hypertrophic scarring,” and “pigmentation.” The evidence was then labeled and circulated to all members of task force for review. Results: The task force is of the opinion that there is insufficient evidence to support the current protocol of avoiding and delaying treatments in the patient group under consideration and recommends that the current practice should be discontinued.The task force concludes that performing procedures such as laser hair removal, fractional lasers for aging and acne scarring, lasers for pigmented skin lesions, fractional radio-frequency microneedling, superficial and medium-depth peels, microdermabrasion, dermaroller, biopsies, radio-frequency ablation, and superficial excisions is safe in patients with concurrent or recent isotretinoin administration.

    2013-01-01

    Introduction The ability of standard operating procedures to improve pre-hospital critical care by changing pre-hospital physician behaviour is uncertain. We report data from a prospective quality control study of the effect on pre-hospital critical care anaesthesiologists’ behaviour of implementing a standard operating procedure for pre-hospital controlled ventilation. Materials and methods Anaesthesiologists from eight pre-hospital critical care teams in the Central Denmark Region prospectively registered pre-hospital advanced airway-management data according to the Utstein-style template. We collected pre-intervention data from February 1st 2011 to January 31st 2012, implemented the standard operating procedure on February 1st 2012 and collected post intervention data from February 1st 2012 until October 31st 2012. We included transported patients of all ages in need of controlled ventilation treated with pre-hospital endotracheal intubation or the insertion of a supraglottic airways device. The objective was to evaluate whether the development and implementation of a standard operating procedure for controlled ventilation during transport could change pre-hospital critical care anaesthesiologists’ behaviour and thereby increase the use of automated ventilators in these patients. Results The implementation of a standard operating procedure increased the overall prevalence of automated ventilator use in transported patients in need of controlled ventilation from 0.40 (0.34-0.47) to 0.74 (0.69-0.80) with a prevalence ratio of 1.85 (1.57-2.19) (p = 0.00). The prevalence of automated ventilator use in transported traumatic brain injury patients in need of controlled ventilation increased from 0.44 (0.26-0.62) to 0.85 (0.62-0.97) with a prevalence ratio of 1.94 (1.26-3.0) (p = 0.0039). The prevalence of automated ventilator use in patients transported after return of spontaneous circulation following pre-hospital cardiac arrest increased from 0.39 (0

    Full Text Available The study focuses on the seven-step procedure (SSP in problem-based learning (PBL. The way students apply the seven-step procedure will help us understand how students work in a problem-based learning curriculum. So far, little is known about how students rate the performance and importance of the different steps, the amount of time they spend on each step and the perceived quality of execution of the procedure. A survey was administered to a sample of 101 students enrolled in a problem-based hospitality management program. Results show that students consider step 6 (Collect additional information outside the group to be most important. The highest performance-rating is for step two (Define the problem and the lowest for step four (Draw a systemic inventory of explanations from step three. Step seven is classified as low in performance and high in importance implicating urgent attention. The average amount of time spent on the seven steps is 133 minutes with the largest part of the time spent on self-study outside the group (42 minutes. The assessment of the execution of a set of specific guidelines (the Blue Card did not completely match with the overall performance ratings for the seven steps. The SSP could be improved by reducing the number of steps and incorporating more attention to group dynamics.

    2006-07-01

    A strong science knowledge base and problem solving skills have always been highly valued for employment in the science industry. Skills currently needed for employment include being able to problem solve (Overtoom, 2000). Academia also recognizes the need for effectively teaching students to apply problem solving skills in clinical settings. This thesis investigates how students solve complex science problems in an academic setting in order to inform the development of problem solving skills for the workplace. Students' use of problem solving skills in the form of learned concepts and procedural knowledge was studied as students completed a problem that might come up in real life. Students were taking a community college sophomore biology course, Human Anatomy & Physiology II. The problem topic was negative feedback inhibition of the thyroid and parathyroid glands. The research questions answered were (1) How well do community college students use a complex of conceptual knowledge when solving a complex science problem? (2) What conceptual knowledge are community college students using correctly, incorrectly, or not using when solving a complex science problem? (3) What problem solving procedural knowledge are community college students using successfully, unsuccessfully, or not using when solving a complex science problem? From the whole class the high academic level participants performed at a mean of 72% correct on chapter test questions which was a low average to fair grade of C-. The middle and low academic participants both failed (F) the test questions (37% and 30% respectively); 29% (9/31) of the students show only a fair performance while 71% (22/31) fail. From the subset sample population of 2 students each from the high, middle, and low academic levels selected from the whole class 35% (8/23) of the concepts were used effectively, 22% (5/23) marginally, and 43% (10/23) poorly. Only 1 concept was used incorrectly by 3/6 of the students and identified as

    A new procedure and reference standards for specifying the structural resolution in coordinate metrology traceable to the SI unit the metre are proposed. With the definition of the structural resolution, a significant gap will be closed to complete ‘acceptance and verification tests’ of the coordinate measuring systems (CMSs) which are specified in the ISO 10360 series dealing with tactile sensors, optical sensors, and x-ray computed tomography measurement systems (CTs). The proposed new procedure uses reference standards with circular rounded edges. The idea is to measure the radius of curvature on a calibrated round edge structure. From the deviation between the measured and the calibrated radius, an analogue Gaussian broadening of the measurement system is determined. This value is a well-defined and easy-to-apply measure to define the structural resolution for dimensional measurements. It is applicable to CMSs which are based on different sensing principles, e.g. tactile, optical and CT systems. On the other hand, it has a physical meaning similar to the classical optical point-spread function. It makes it possible to predict which smallest details the CMS is capable of measuring reliably for an arbitrary object shape. The theoretical background of the new procedure is given, an appropriate reference standard is described and comparative, quantitative measurement data of CMSs featuring different sensors are shown.

    Infertility affects over 70 million couples globally. Access to, and interest in, assisted reproductive technologies is growing worldwide, with more couples seeking medical intervention to conceive, in particular by IVF. Despite numerous advances in IVF techniques since its first success in 1978, almost half of the patients treated remain childless. The multifactorial nature of IVF treatment means that success is dependent on many variables. Therefore, it is important to examine how each variable can be optimized to achieve the best possible outcomes for patients. The current approach to IVF is fragmented, with various protocols in use. A systematic approach to establishing optimum best practices may improve IVF success and live birth rates. Our vision of the future is that technological advancements in the laboratory setting are standardized and universally adopted to enable a gold standard of care. Implementation of best practices for laboratory procedures will enable clinicians to generate high-quality gametes, and to produce and identify gametes and embryos of maximum viability and implantation potential, which should contribute to improving take-home healthy baby rates.

    2005-10-01

    The finite volume method of radiation is implemented for complex 3-D problems in order to use it for combined heat transfer problems in connection with CFD codes. The method is applied for a 3-D block structured grid in a radiatively participating medium. The method is implemented in non-orthogonal curvilinear coordinates so that it can handle irregular structure with a body-fitted structured grid. The multiblocking is performed with overlapping blocks to exchange the information between the blocks. Five test problems are considered in this work. In the first problem, present work is validated with the results of the literature. To check the accuracy of multiblocking, a single block is divided into four blocks and results are validated against the results of the single block simulated alone in the second problem. Complicated geometries are considered to show the applicability of the present procedure in the last three problems. Both radiative and non-radiative equilibrium situations are considered along with an absorbing, emitting and scattering medium. (author)

  10. Standardization of specifications and inspection procedures for LEU plate-type research reactor fuels

    International Nuclear Information System (INIS)

    1988-06-01

    With the transition to high density uranium LEU fuel, fabrication costs of research reactor fuel elements have a tendency to increase because of two reasons. First, the amount of the powder of the uranium compound required increases by more than a factor of five. Second, fabrication requirements are in many cases nearer the fabrication limits. Therefore, it is important that measures be undertaken to eliminate or reduce unnecessary requirements in the specification or inspection procedures of research reactor fuel elements utilizing LEU. An additional stimulus for standardizing specifications and inspection procedures at this time is provided by the fact that most LEU conversions will occur within a short time span, and that nearly all of them will require preparation of new specifications and inspection procedures. In this sense, the LEU conversions offer an opportunity for improving the rationality and efficiency of the fuel fabrication and inspection processes. This report focuses on the standardization of specifications and inspection processes of high uranium density LEU fuels for research reactors. However, in many cases the results can also be extended directly to other research reactor fuels. 15 refs, 1 fig., 3 tabs

  11. Solving a Production Scheduling Problem by Means of Two Biobjective Metaheuristic Procedures

    2009-11-01

    Production planning and scheduling problems emphasize the need for the availability of management tools that can help to assure proper service levels to customers, maintaining, at the same time, the production costs at acceptable levels and maximizing the utilization of the production facilities. In this case, a production scheduling problem that arises in the context of the activities of a company dedicated to the manufacturing of furniture for children and teenagers is addressed. Two bicriteria metaheuristic procedures are proposed to solve the sequencing problem in a production equipment that constitutes the bottleneck of the production process of the company. The production scheduling problem can be characterized as a general flow shop with sequence dependant setup times and additional inventory constraints. Two objectives are simultaneously taken into account when the quality of the candidate solutions is evaluated: the minimization of completion time of all jobs, or makespan, and the minimization of the total flow time of all jobs. Both procedures are based on a local search strategy that responds to the structure of the simulated annealing metaheuristic. In this case, both metaheuristic approaches generate a set of solutions that provides an approximation to the optimal Pareto front. In order to evaluate the performance of the proposed techniques a series of experiments was conducted. After analyzing the results, it can be said that the solutions provided by both approaches are adequate from the viewpoint of the quality as well as the computational effort involved in their generation. Nevertheless, a further refinement of the proposed procedures should be implemented with the aim of facilitating a quasi-automatic definition of the solution parameters.

    The Department of Energy (DOE) Nuclear Material Production Facilities at the Savannah River Site (SRS) were designed, constructed, and placed into operation in the early 1950's, based on existing industry codes/standards, design criteria, analytical procedures. Since that time, DOE has developed Orders and Polices for the planning, design and construction of DOE Nuclear Reactor Facilities which invoke or reference commercial nuclear reactor codes and standards. The application of IEEE reactor design requirements such as Equipment Qualification, Seismic Qualification, Single Failure Criteria, and Separation Requirement, to non-reactor facilities has been a problem since the IEEE reactor criteria do not directly confirm to the needs of non-reactor facilities. SRS Systems Engineering is developing a methodology for the application of IEEE Standards to non-reactor facilities at SRS

  14. The hierarchy problem and the cosmological constant problem in the Standard Model

    International Nuclear Information System (INIS)

    Jegerlehner, Fred

    2015-03-01

    We argue that the SM in the Higgs phase does not suffer form a ''hierarchy problem'' and that similarly the ''cosmological constant problem'' resolves itself if we understand the SM as a low energy effective theory emerging from a cut-off medium at the Planck scale. We discuss these issues under the condition of a stable Higgs vacuum, which allows to extend the SM up to the Planck length. The bare Higgs boson mass then changes sign below the Planck scale, such the the SM in the early universe is in the symmetric phase. The cut-off enhanced Higgs mass term as well as the quartically enhanced cosmological constant term trigger the inflation of the early universe. The coefficients of the shift between bare and renormalized Higgs mass as well as of the shift between bare and renormalized vacuum energy density exhibit close-by zeros at some point below the Planck scale. The zeros are matching points between short distance and the renormalized low energy quantities. Since inflation tunes the total energy density to take the critical value of a flat universe Ω tot =ρ tot /ρ crit =Ω Λ +Ω matter +Ω radiation =1 it is obvious that Ω Λ today is of order Ω tot given that 1>Ω matter , Ω radiation >0, which saturate the total density to about 26 % only, the dominant part being dark matter(21%).

    The objective of this work is to solve a doubt appeared in the standard procedure of KWU/Siemens for fuel assembly (FA) with gadolinium. In this procedure, the σ's and form functions of such assembly are modified by his effective heterogeneity factor factor (f eff ), which is defined as the ratio between the heterogeneity factors (f het ) of FA's with and without poison. The doubt appeared at the time to calculated the f het of FA without poison: should one consider the pure FA or the FA with poison in which the concentration of gadolinium would be set to zero, but one should keep that of natural uranium? The best results were obtained considering the second hypothesis. (author)

    2010-01-01

    Refractory metal heat pipes developed during this project shall be subjected to various operating conditions to evaluate life-limiting corrosion factors. To accomplish this objective, various parameters shall be investigated, including the effect of temperature and mass fluence on long-term corrosion rate. The test series will begin with a performance test of one module to evaluate its performance and to establish the temperature and power settings for the remaining modules. The performance test will be followed by round-the-clock testing of 16 heat pipes. All heat pipes shall be nondestructively inspected at 6-month intervals. At longer intervals, specific modules will be destructively evaluated. Both the nondestructive and destructive evaluations shall be coordinated with Los Alamos National Laboratory. During the processing, setup, and testing of the heat pipes, standard operating procedures shall be developed. Initial procedures are listed here and, as hardware is developed, will be updated, incorporating findings and lessons learned.

    A modern method has been described to assess the radiation burden by X-ray procedures with consideration of the standards of our Society for Medical Radiology in the GDR. The underlying methodology is a Monte Carlo computer technique, which simulates stochastically the energy deposition of X-ray photons in a mathematically described heterogeneous anthropomorphic phantom by Rosenstein (US Department of Health, Education and Welfare). To apply the procedure specific values for the following parameters must be determined for each dose estimation: projection and view, X-ray field size and location entrance exposure at skin surface, beam quality, source-to-image receptor distance. The base data are obtained in terms of tissue-air ratio. Organ doses were calculated for chest, urography, skull, cervical spine, thoracic spine, lumbar spine, pelvis and lymphography. Concluding possibilities have been discussed for reduction of radiation burden. 9 refs., 6 figs., 9 tabs. (author)

    Full Text Available Land is scarce and it is the most important resource that humans rely on. Therefore, the protection of land interests is extremely important. Land acquisition deprives the owner's interest on land. A fair and adequate compensation as well as transparent procedures are crucial for land acquisition. The aims of this study are to investigate the adequacy of compensation for land acquisition in China as compared to the Malaysian framework, and to enhance the understanding of land acquisition procedures and determination of compensation in both China and Malaysia. A case study was conducted to investigate whether the compensation for land acquisition in China is adequate and equitable. Two sets of compensation have been calculated, one based on the current compensation standard executed in China; and the other, calculated based on the market value of the land. The finding reveals that the compensation based on the current compensation standard in China is inadequate. The compensation determined by compensation standard executed varied with the market value of the land. In order to better protect the dispossessed owners in China, the compensation for land acquisition should be based on the market value of the land and other related matters such as betterment, severance, injurious affection, incidental expenses and accommodation works should be given due consideration.

    The benefits of converting to ICD-10-CM/PCS have been well documented in recent years. One of the greatest challenges in the conversion, however, is how to train the workforce in the code sets. The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) has been described as a language requiring higher-level reasoning skills because of the system's increased granularity. Training and problem-solving strategies required for correct procedural coding are unclear. The objective of this article is to propose that the acquisition of rule-based logic will need to be augmented with self-evaluative and critical thinking. Awareness of how this process works is helpful for established coders as well as for a new generation of coders who will master the complexities of the system.

    2014-01-01

    Full Text Available The new criminal procedure, set forth in 2011, represents a compilation of the inquisitive model of preliminary proceedings, on the one hand, and adversarial trial of the Anglo-American type of criminal procedure on the other. Introduction of the public prosecutor's investigation required a subtle legislative approach to the protection of human rights in criminal proceedings, in order to establish equilibrium between efficient and just procedure. Instead of the expected, the erroneous conception based on the ideas that the public prosecutor's investigation should be strictly formal as that of a court, that evidence taken by the non-judicial authorities should have the same bearing as those taken by the courts, and that the court should have no role in conducting investigation, resulted in an overly inferior position of the accuses compared to that of the public prosecutor. Beside the fact that such conception can not pass the ECJ test, the specific legal solutions referring the investigation open the question of harmonization with the European legal standards. The provisions on initiation of this phase of the proceedings, not being legally sanctioned, put in question the right of the accused to access justice, as well as his right to an effective legal remedy, and the introduced investigation against the unknown perpetrator, the right to be present at one's own trial is being jeopardized. Neither do all procedural rules pertaining to the trial support the fair procedure principle: the indirect extortion of evidence from the defense is discordant with the rule that the burden of proof lies on the prosecutor, as one of the main pillars of the assumption of innocence; as well as the broad opportunity to use non-judicial evidence at the hearing without any major legal obstacles, have demolished the principles of directness and contradictoriness.

    The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. This document establishes Federal standards and procedures for creating the WBD as seamless and hierarchical hydrologic unit data, based on topographic and hydrologic features at a 1:24,000 scale in the United States, except for Alaska at 1:63,360 scale, and 1:25,000 scale in the Caribbean. The data within the WBD have been reviewed for certification through the 12-digit hydrologic unit for compliance with the criteria outlined in this document. Any edits to certified data will be reviewed against this standard prior to inclusion. Although not required as part of the framework WBD, the guidelines contain details for compiling and delineating the boundaries of two additional levels, the 14- and 16-digit hydrologic units, as well as the use of higher resolution base information to improve delineations. The guidelines presented herein are designed to enable local, regional, and national partners to delineate hydrologic units consistently and accurately. Such consistency improves watershed management through efficient sharing of information and resources and by ensuring that digital geographic data are usable with other related Geographic Information System (GIS) data.Terminology, definitions, and procedural information are provided to ensure uniformity in hydrologic unit boundaries, names, and numerical codes. Detailed standards and specifications for data are included.

    2018-03-01

    Full Text Available Objective: To use these growth charts to critically assess sufficiency of cases and parity of cases between residents, and to compare these growth charts to available international standards for minimum case numbers. Methods: Operative Log Growth Charts were developed for key indicator procedures for graduating otolaryngology residents in 2012-2014 at a large teaching hospital in the capital city of a newly industrialized country. Comparisons were made between years of training and required minimum case numbers published by the ACGME RRC for Otolaryngology. Results: Data was available to create 7 key indicator operative log growth charts to include all available data from 2012-2014 residents. These growth charts were used to assess growth in operative procedures for residents in the program compared to historical norms in the program. Graduating residents surpassed ACGME minimum case numbers in Bronchoscopy only and were below the minimum numbers for the other key indicators tested. Conclusion: There is significant heterogeneity in the standards for otolaryngology training between countries. It is possible to develop program-specific and country-specific operative log growth charts.

    Atrial fibrillation (AF) is the most common cardiac arrhythmia and the treatment options include medical treatment and catheter-based or surgical interventions. AF is a major cause of stroke, and its prevalence is increasing. The surgical treatment of AF has been revolutionized over the past 2 decades through surgical innovation and improvements in endoscopic imaging, ablation technology and surgical instrumentation. The Cox-maze (CM) procedure, which was developed by James Cox and introduced clinically in 1987, is a procedure in which multiple incisions are created in both the left and the right atria to eliminate AF while allowing the sinus impulse to reach the atrioventricular node. This procedure became the gold standard for the surgical treatment of AF. Its latest iteration is termed the CM IV and was introduced in 2002. The CM IV replaced the previous cut-and-sew method (CM III) by replacing most of the incisions with a combination of bipolar radiofrequency and cryoablation. The use of ablation technologies, made the CM IV technically easier, faster and more amenable to minimally invasive approaches. The aims of this article are to review the indications and preoperative planning for the CM IV, to describe the operative technique and to review the literature including comparisons of the CM IV with the previous cut-and-sew method. Finally, this review explores future directions for the surgical treatment of patients with AF.

In our problem the state value at the final time the state, y(T = z, is free and unknown, and additionally the Lagrangian integrand in the functional is a piecewise constant function of the unknown value y(T. This is not a standard optimal control problem and cannot be solved using Pontryagin's Minimum Principle with the standard boundary conditions at the final time. In the standard problem a free final state y(T yields a necessary boundary condition p(T = 0, where p(t is the costate. Because the integrand is a function of y(T, the new necessary condition is that y(T should be equal to a certain integral that is a continuous function of y(T. We introduce a continuous approximation of the piecewise constant integrand function by using a hyperbolic tangent approach and solve an example using a C++ shooting algorithm with Newton iteration for solving the Two Point Boundary Value Problem (TPBVP. The minimising free value y(T is calculated in an outer loop iteration using the Golden Section or Brent algorithm. Comparative nonlinear programming (NP discrete-time results are also presented.

    Mammography is one widely used technique in the detection of breast cancer. In order to optimize the results achieving better images with lower dose rates, a quality assurance programme must be applied to the equipment. Some control tests use ionization chambers to measure air kerma and other quantities. These tests can only be reliable if the ionization chambers used on them are correctly calibrated. In the present work, it was developed a standard operating procedure (SOP) for quality control tests in a commercial mammography equipment installed in the Calibration Laboratory (LCI) at IPEN - Brazilian Institute for energy and nuclear research). Seven tests were performed in the equipment: Tube voltage and exposition time accuracy and reproducibility, linearity and reproducibility of Air kerma and Half Value Layer (HVL). Then, it was made a measurement of the air kerma in the mammography equipment, using a reference ionization chamber with traceability to a primary laboratory in Germany (Physikalisch-Technische Bundesanstalt - PTB), that was later compared with the air kerma measured in an industrial irradiator. This industrial X-ray generator was recently used in the implementation of X-radiation Standards beams, mammography level, following the Standard IEC 61267. The HVL values varied from 0.36 (25kV) to 0.41 mmA1 (35kV), and the measured air kerma rates were between 9.78 and 17.97 mGy/min. (author)

    For the determination of contamination on wafer surfaces with total reflection x-ray fluorescence spectrometry (TXRF) normally external 1 ng Ni droplet standards were used for calibration. This method is based on several assumptions about the properties of the standard droplet which are strongly affected by the preparation of the samples. In this paper a study is resented which compares the external droplet method with a calibration procedure using the fundamental physical background of total reflection x-ray fluorescence spectrometry and the properties of Ni bulk material. The particular features of the two methods will be discussed and the obtained results compared to each other. It is demonstrated in this study that the calibration with Ni bulk material is a primary method which offers several advantages compared to the calibration based on droplet standards. These advantages are unique and enable a more reliable and reproducible quantification of contamination on wafer surfaces. This is caused by the fact that the method is standardless and only based on fundamental parameters and natural constants. It is also demonstrated that effects which could be caused by especial features of the measured samples (particle or film, e.g.) or by the degradation of the calibration sample could be excluded.

    Full Text Available In today’s global market, companies are constantly confronted with the competition on the local, national and international level. Companies therefore use a variety of strategies and tools to become and/or remain competitive. Potential areas for cost reduction in companies are supply chain management and logistic and customs procedures. Implementation of various logistic standards in supply chain management can provide significant cost savings for the company’s daily operations and thus reduce overall costs and improve the competitiveness. Using different customs procedures and logistic standards to reduce their costs and become more competitive in the market is necessary for Croatian companies. The method of using these tools is not a one-time process and requires constant efforts. Companies therefore have to be ready to improve daily to be and remain competitive. Using a variety of modern customs procedures can save their money and time, not only through these procedures, but also through better use of their employee’s time, their own vehicles and other equipment. The paper analyzes various customs procedures and logistic standards that can help companies save time and money and improve their competitiveness. In the example of Croatian company, which uses various available procedures and standards the benefits of their use are shown. Apart from bringing savings in operations, all these procedures and standards allow the company to be better, cheaper and more attractive to buyers.

  10. Calibration of photon and beta ray sources used in brachytherapy. Guidelines on standardized procedures at Secondary Standards Dosimetry Laboratories

    International Nuclear Information System (INIS)

    2004-03-01

    It has generally been recognized that international harmonization in radiotherapy dosimetry is essential. Consequently, the IAEA has given much effort to this, for example by publishing a number of reports in the Technical Reports Series (TRS) for external beam dosimetry, most notably TRS-277 and more recently TRS-398. Both of these reports describe in detail the steps to be taken for absorbed dose determination in water and they are often referred to as 'dosimetry protocols'. Similar to TRS-277, it is expected that TRS-398 will be adopted or used as a model by a large number of countries as their national protocol. In 1996, the IAEA established a calibration service for low dose rate (LDR) 137 Cs brachytherapy sources, which is the most widely used source for treatment of gynecological cancer. To further enhance harmonization in brachytherapy dosimetry, the IAEA published in 1999 IAEA-TECDOC-1079 entitled 'Calibration of Brachytherapy Sources. Guidelines on Standardized Procedures for the Calibration of Brachytherapy Sources at Secondary Standard Dosimetry Laboratories (SSDLs) and Hospitals'. The report was well received and was distributed in a large number of copies to the members of the IAEA/WHO network of SSDLs and to medical physicists working with brachytherapy. The present report is an update of the aforementioned TECDOC. Whereas TECDOC-1079 described methods for calibrating brachytherapy sources with photon energies at or above those of 192 Ir, the current report has a wider scope in that it deals with standardization of calibration of all the most commonly used brachytherapy sources, including both photon and beta emitting sources. The latter sources have been in use for a few decades already, but their calibration methods have been unclear. Methods are also described for calibrating sources used in the rapidly growing field of cardiovascular angioplasty. In this application, irradiation of the vessel wall is done in an attempt to prevent restenosis after

    A list of standard reference frequency values (LoF) of quantum transitions from the microwave to the optical regime has been recommended by the International Committee for Weights and Measures (Comité international des poids et mesures, CIPM) for use in basic research, technology, and for the metrology of time, frequency and length. The CIPM LoF contains entries that are recommended as secondary representations of the second in the International System of Units, and entries that can be used to serve as realizations of the definition of the metre. The historical perspective that led to the CIPM LoF is outlined. Procedures have been developed for updating existing, and validating new, entries into the CIPM LoF. The CIPM LoF might serve as an entry for a future redefinition of the second by an optical transition.

    The action verbs used in Emergency Operating Procedures (EOPs) for each nuclear power plant are translated respectively from the action verbs used in Emergency Recovery Guidelines (ERG) of the reference plants. The action verbs used in each plant are not largely different with one another. There are, however, some cases that the meanings of the same action verbs used in different plants are not consistent with each other and translations are not exact. In this study, the original English expressions of the action verbs and the translated verbs were compared and their accepted meanings analyzed. And then, standardization for the action verbs which are not exactly translated or which are used with different meanings among the plants was proposed

    2000-01-01

    An exposure chart is very important in conducting radiographic inspection of materials. By using an accurate exposure chart, an inspector is able to avoid a trial and error way of determining correct time to expose a specimen, thereby producing a radiograph that has an acceptable density based on a standard. The chart gives the following information: x-ray machine model and brand, distance of the x-ray tube from the film, type and thickness of intensifying screens, film type, radiograph density, and film processing conditions. The methods of preparing an exposure chart are available in existing radiographic testing manuals. These described methods are presented in step by step procedures, covering the actual laboratory set-up, data gathering, computations, and transformation of derived data into Characteristic Curve and Exposure Chart

    Full Text Available In contrast to the standard evaluation of the efficacy of pesticides and the testing of spraying equipment there are no comparable testing procedure for equipment of thermal weed control. It is the aim of the investigations described here to develop a standard procedure for assessing temperature distribution and biological efficacy. This will be the basis for quality testing which can be directly used by practical users. Also it can help engineers to improve devices if constructive gaps will be identified by these tests. The results from testing a flaming device (Green-Flame 850 E demonstrated such a potential for technical improvement: The temperature decreased from 159 °C to 89 °C by increasing driving speed from 0.35 m/s to 0.81 m/s. The variation of the temperature related to the working width was extremely high: The range was 60 °C at highest speed and 79 °C at lowest speed, respectively. The biological efficacy against the test plant species Sinapis arvensis was also affected by the driving speed and the corresponding temperature. A driving speed not higher than 0.53 m/s resulted in efficacy rates of almost 95%. However, the efficacy was only 66% at the highest tested speed of 0.81 m/s. Thus, the needed effective temperature is between 89 °C und 106 °C. In contrast, Lolium perenne was controlled by only 72% under the tested conditions. Here a dose-response relationship was not observed. The variation of the temperature, as well as the biological efficacy, was extremely heterogeneous and not satisfying in terms of an economic and safe use. Similar results were found for other devices on thermal weed control.

    Stevia rebaudiana Bertoni is a non-caloric natural sweetener which is 300 times sweeter than cane sugar. Extracts from stevia leaves has vast application in food and beverages based industries, can be added to tea and coffee, cooked or baked goods, processed foods and confectionary goods. Recently, stevia attained awareness owing to its natural, non-caloric sweetness by diet/ health conscious and diabetic persons (Arpita et al., 2011). This natural sweetener has high commercial value in global market, it was estimated that global market value for stevia is be around USD11 billion by year 2015. Although stevia is being largely popularized in Malaysia and other countries but large-scale propagation procedures for the continuous supply of planting materials in commercial plantation has yet to be established, optimized and standardized. Furthermore, propagation through stevia seeds is often very difficult due to self-incompatibility which results in sterile seeds (Sakaguchi et al., 1982). Tissue culture is the only rapid process for the mass propagation of stevia and there have been few reports of in vitro growth of stevia (Miyagaya et al., 1986) and in vitro micropropagation from shoot tip and leaf (Uddin et al., 2006). Hence, study was carried out to establish a suitable protocol for in vitro propagation of S. rebaudiana Bertoni that can be further up-scaled for mass propagation of stevia seedlings. The established Standard Operating Procedure (SOP) will ensure rapid and efficient production of stevia tissue culture seedlings for continuous supply of planting materials for commercial stevia plantations in Malaysia. Preparation of growth medium, multiplication of shoots, rooting of plant lets and hardening of ex-vitro rooted plant lets is discussed in this paper. (author)

  19. California residential energy standards: problems and recommendations relating to implementation, enforcement, and design. [Thermal insulation

    Energy Technology Data Exchange (ETDEWEB)

    1977-08-01

    Documents relevant to the development and implementation of the California energy insulation standards for new residential buildings were evaluated and a survey was conducted to determine problems encountered in the implementation, enforcement, and design aspects of the standards. The impact of the standards on enforcement agencies, designers, builders and developers, manufacturers and suppliers, consumers, and the building process in general is summarized. The impact on construction costs and energy savings varies considerably because of the wide variation in prior insulation practices and climatic conditions in California. The report concludes with a series of recommendations covering all levels of government and the building process. (MCW)

  20. Collection of Pyrethroids in Water and Sediment Matrices: Development and Validation of a Standard Operating Procedure

    Loss of pyrethroid insecticides onto surfaces during sample collection can confound the interpretation of analytical and toxicity test results. Sample collection devices, container materials, and water matrix composition have a significant influence on the association of pyrethroids to container walls, which can be as high as 50 percent. Any sample collection method involving transfer through multiple containers or pieces of equipment increases the potential for pyrethroid loss. This loose 'surface-association' with container walls can be reversed through agitation. When sampling water matrices with pumps or autosamplers, no pyrethroids were lost as long as the water was moving continuously through the system. When collecting water matrices in containers, the material with the least amount of pyrethroid sorption is as follows: glass less than (pyrethroids were easier to re-suspend from the glass container walls. Since the amount of surface-association is proportional to the ratio of volume-to-contact-area of the sample, taking larger-volume field samples (greater than 3 liters) reduced pyrethroid losses to less than 10 percent. The amount of surface-association cannot be predicted easily because of the dependence on water matrix composition; samples with higher dissolved organic carbon or suspended-sediment concentrations were observed to have lower percent loss. Sediment samples were not affected by glass-container sorption (the only containers tested). Standardized sample-collection protocols are critical to yield accurate pyrethroid concentrations for assessment of potential effects, and have been summarized in an accompanying standard operating procedure.

    In a recent longitudinal surveillance study in 30 U.S. retail delicatessens, 9.7% of environmental surfaces were positive for Listeria monocytogenes, and we found substantial evidence of persistence. In this study, we aimed to reduce the prevalence and persistence of L. monocytogenes in the retail deli environment by developing and implementing practical and feasible intervention strategies (i.e., sanitation standard operating procedures; SSOPs). These SSOPs were standardized across the 30 delis enrolled in this study. SSOP implementation was verified by systems inherent to each retailer. Each deli also was equipped with ATP monitoring systems to verify effective sanitation. We evaluated intervention strategy efficacy by testing 28 food and nonfood contact surfaces for L. monocytogenes for 6 months in all 30 retail delis. The efficacy of the intervention on the delis compared with preintervention prevalence level was not statistically significant; we found that L. monocytogenes could persist despite implementation of enhanced SSOPs. Systematic and accurate use of ATP monitoring systems varied widely among delis. The findings indicate that intervention strategies in the form of enhanced daily SSOPs were not sufficient to eliminate L. monocytogenes from highly prevalent and persistently contaminated delis and that more aggressive strategies (e.g., deep cleaning or capital investment in redesign or equipment) may be necessary to fully mitigate persistent contamination.

    A small animal veterinarian in Washington State developed leptospirosis after an occupational exposure. Approximately 10 days prior to the onset of illness, he examined a healthy appearing pet rat for fleas, which urinated on his un-gloved hands. Although the veterinarian washed his hands after the examination, his hands had abrasions from gardening. The veterinarian was hospitalized for 12 days and was able to return to work part-time 1 month following discharge. This illness may have been prevented if the veterinarian had been wearing gloves during the examination as recommended by the National Association of State Public Health Veterinarians (NASPHV), Veterinary Infection Control Committee, in its Compendium of Veterinary Standard Precautions for Zoonotic Disease Prevention in Veterinary Personnel (2008). This case alerts us to the need for small animal veterinarians to minimize their infection risk by practising recommended infection control procedures. Veterinarians should establish and follow a written infection control plan based on the standardized infection control approach adopted by the NASPHV to minimize their risk of occupational zoonotic infections.

  3. A standard operating procedure for the surgical implantation of transmitters in juvenile salmonids

    Biotelemetry is a useful tool to monitor the movements of animals and is widely applied in fisheries research. Radio or acoustic technology can be used, depending on the study design and the environmental conditions in the study area. A broad definition of telemetry also includes the use of Passive Integrated Transponder (PIT) tags, either separately or with a radio or acoustic transmitter. To use telemetry, fish must be equipped with a transmitter. Although there are several attachment procedures available, surgical implantation of transmitters in the abdominal cavity is recognized as the best technique for long-term telemetry studies in general (Stasko and Pincock, 1977; Winter, 1996; Jepsen, 2003), and specifically for juvenile salmonids, Oncorhynchus spp. (Adams and others, 1998a, 1998b; Martinelli and others, 1998; Hall and others, 2009). Studies that use telemetry assume that the processes by which the animals are captured, handled, and tagged, as well as the act of carrying the transmitter, will have minimal effect on their behavior and performance. This assumption, commonly stated as a lack of transmitter effects, must be valid if telemetry studies are to describe accurately the movements and behavior of an entire population of interest, rather than the subset of that population that carries transmitters. This document describes a standard operating procedure (SOP) for surgical implantation of radio or acoustic transmitters in juvenile salmonids. The procedures were developed from a broad base of published information, laboratory experiments, and practical experience in tagging thousands of fish for numerous studies of juvenile salmon movements near Columbia River and Snake River hydroelectric dams. Staff from the Western Fisheries Research Center's Columbia River Research Laboratory (CRRL) frequently have used telemetry studies to evaluate new structures or operations at hydroelectric dams in the Columbia River Basin, and these evaluations typically

    Full Text Available PURPOSE: The study here presented was done to test the technical reliability and immediate efficacy of the Acucise device using a standardized technique. MATERIALS AND METHODS: 56 Acucise procedures were performed in pigs by a single surgeon who used a standardized technique: insert 5F angiographic catheter bilaterally up to the midureter, perform retrograde pyelogram, Amplatz super-stiff guidewire is advanced up to the level of the renal pelvis, angiographic catheters are removed, Acucise catheter balloon is advanced to the ureteropelvic junction (UPJ level, the super-stiff guide-wire is removed and the contrast medium in the renal pelvis is aspirated and replaced with distilled water, activate Acucise at 75 watts of pure cutting current, keep the balloon fully inflated for 10 minutes, perform retrograde ureteropyelogram to document extravasation, remove Acucise catheter and pass an ureteral stent and remove guide-wire. RESULTS: In no case did the Acucise device present malfunction. The electrocautery activation time was 2.2 seconds (ranging from 2 to 4 seconds. The extravasation of contrast medium, visible by fluoroscopy, occurred in 53 of the 56 cases (94.6%. In no case there was any evidence of intraoperative hemorrhage. CONCLUSIONS: This study revealed that performing Acucise endopyelotomy routinely in a standardized manner could largely preclude intraoperative device malfunction and eliminate complications while achieving a successful incision in the UPJ. With the guidelines that were used in this study, we believe that Acucise endopyelotomy can be completed successfully and safely in the majority of selected patients with UPJ obstruction.

    The use of radiotherapy implies the necessity of rigorous quality standards in its different components, aimed to provide the best possible treatment and avoid potential patients' risks, that could even cause him death. Projects of technical cooperation developed in Cuba and supported by the International Atomic Energy Agency address the implementation of Programs of Quality Assurance (PGC) in radiotherapy services. The establishment of the National Quality Audit Program (PNAC) is a superior stage. The National Control Center for Medical Devices, as the national regulator entity for the control and supervision of medical devices in the National Health System, is responsible for the making and execution of the PNAC. The audit modality selected was the inspection visit in situ due to its intrinsic advantages, our geographical extension and the number of radiotherapy services. This paper presents the methodology for the execution of the PNAC, in form of a Normalized Procedure of Operation (PNO) that defines the objectives, scope, terms and definitions, responsibilities, composition and selection of the auditor team, security's conditions, materials and equipment, steps of the audit execution, results calculation and interpretation, records, etc. (author)

  10. Qualitative research within trials: developing a standard operating procedure for a clinical trials unit

    Science.gov (United States)

    2013-01-01

    Background Qualitative research methods are increasingly used within clinical trials to address broader research questions than can be addressed by quantitative methods alone. These methods enable health professionals, service users, and other stakeholders to contribute their views and experiences to evaluation of healthcare treatments, interventions, or policies, and influence the design of trials. Qualitative data often contribute information that is better able to reform policy or influence design. Methods Health services researchers, including trialists, clinicians, and qualitative researchers, worked collaboratively to develop a comprehensive portfolio of standard operating procedures (SOPs) for the West Wales Organisation for Rigorous Trials in Health (WWORTH), a clinical trials unit (CTU) at Swansea University, which has recently achieved registration with the UK Clinical Research Collaboration (UKCRC). Although the UKCRC requires a total of 25 SOPs from registered CTUs, WWORTH chose to add an additional qualitative-methods SOP (QM-SOP). Results The qualitative methods SOP (QM-SOP) defines good practice in designing and implementing qualitative components of trials, while allowing flexibility of approach and method. Its basic principles are that: qualitative researchers should be contributors from the start of trials with qualitative potential; the qualitative component should have clear aims; and the main study publication should report on the qualitative component. Conclusions We recommend that CTUs consider developing a QM-SOP to enhance the conduct of quantitative trials by adding qualitative data and analysis. We judge that this improves the value of quantitative trials, and contributes to the future development of multi-method trials. PMID:23433341

    Qualitative research methods are increasingly used within clinical trials to address broader research questions than can be addressed by quantitative methods alone. These methods enable health professionals, service users, and other stakeholders to contribute their views and experiences to evaluation of healthcare treatments, interventions, or policies, and influence the design of trials. Qualitative data often contribute information that is better able to reform policy or influence design. Health services researchers, including trialists, clinicians, and qualitative researchers, worked collaboratively to develop a comprehensive portfolio of standard operating procedures (SOPs) for the West Wales Organisation for Rigorous Trials in Health (WWORTH), a clinical trials unit (CTU) at Swansea University, which has recently achieved registration with the UK Clinical Research Collaboration (UKCRC). Although the UKCRC requires a total of 25 SOPs from registered CTUs, WWORTH chose to add an additional qualitative-methods SOP (QM-SOP). The qualitative methods SOP (QM-SOP) defines good practice in designing and implementing qualitative components of trials, while allowing flexibility of approach and method. Its basic principles are that: qualitative researchers should be contributors from the start of trials with qualitative potential; the qualitative component should have clear aims; and the main study publication should report on the qualitative component. We recommend that CTUs consider developing a QM-SOP to enhance the conduct of quantitative trials by adding qualitative data and analysis. We judge that this improves the value of quantitative trials, and contributes to the future development of multi-method trials.

    Full Text Available Medication errors occurring in hospitals are a growing national concern. These medication errors and their related costs (or wastes are seen as major factors leading to increased patient safety risks and increased waste in the hospital setting.  This article presents a study in which sixteen entry-level nurses utilized a Toyota Production System (TPS analysis procedure to solve medication delivery problems at one community hospital. The objective of this research was to study and evaluate the TPS analysis procedure for problem solving with entry-level nurses. Personal journals, focus group discussions, and a survey study were used to collect data about entry-level nurses’ perceptions of using the TPS problem solving approach to study medication delivery. A regression analysis was used to identify characteristics that enhance problem solving efforts. In addition, propositions for effective problem solving by entry-level nurses to aid in the reduction of medication errors in healthcare delivery settings are offered.

  13. Problems encountered in embodying the principles of ICRP-26 and the revised IAEA safety standards into UK national legislation

    1979-01-01

    This paper describes the United Kingdom procedures and format for safety legislation and goes on to show how the necessary legislation for radiological protection will fit into the general framework. The United Kingdom, as a member of the European Community and EURATOM, is bound to implement the Euratom Directive on radiological protection within the next few years. The latest draft of the Directive takes account of the recommendations of ICRP-26 and further, a recent draft of the revised IAEA Basic Safety Standards is a composite of both the Directive and ICRP-26. Thus, the effect of embodying the principles of the Directive is to embody the principles of ICRP-26 and the Basic Safety Standards. Some of the problems which have been met are described and in particular there is discussion of the problems arising from the incorporation of the three ICRP-26 facets of dose control, namely justification, optimization and limitation, into a legislative package. The UK system of evolving safety legislation now requires considerable participation by all the parties affected (or by their representatives). This paper indicates that the involvement of persons affected, coupled with a legislative package which consists of a hierarchy of (a) regulations; (b) codes of practice; and (c) guidance notes, will result in the fundamental principles of ICRP-26 being incorporated into UK legislation in a totally acceptable way.

    In part 1 of this series about problems of financing capital goods the multiple and partly diametric economic effects of financing instruments were presented using the leasing procedure as an example. The result indicated that due to the complexity of these effects the choice of a specific financing instrument requires an individual consideration. Therefore, part 2 of the series introduces the method of dynamic capital budgeting which allows the instruments discussed in part 1 to be compared with each other and helps to evaluate their economic benefits. More precisely this paper focuses on a comparative analysis of the most common alternatives, leasing, credit financing and investment financing by the state. In this context, after having identified the total costs of ownership of anesthesia devices, the final asset values of the three financing instruments can be compared with each other using the method of dynamic capital budgeting. In contrast to the prevailing opinion, the results show that from a purely fiscal perspective leasing anesthesia devices is the most expensive alternative. Given the fact that no financial support is available from the state, the option of credit financing turns out to be the most preferable alternative from a relatively limited pool of possibilities. However, it still remains to be answered whether credit financing can defend this position against further, innovative forms of debt financing (e.g., factoring, asset-backed securities, hedge funds, mezzanine capital, etc.).

    2014-01-01

    This book results from a long-term research effort aimed at tackling complex non-standard packing issues which arise in space engineering. The main research objective is to optimize cargo loading and arrangement, in compliance with a set of stringent rules. Complicated geometrical aspects are also taken into account, in addition to balancing conditions based on attitude control specifications. Chapter 1 introduces the class of non-standard packing problems studied. Chapter 2 gives a detailed explanation of a general model for the orthogonal packing of tetris-like items in a convex domain. A number of additional conditions are looked at in depth, including the prefixed orientation of subsets of items, the presence of unusable holes, separation planes and structural elements, relative distance bounds as well as static and dynamic balancing requirements. The relative feasibility sub-problem which is a special case that does not have an optimization criterion is discussed in Chapter 3. This setting can be exploit...

    Spectral obtained with VLT/UVES suggest the existence of the 6 Li isotope in several metal-poor stars at a level that challenges ideas about its synthesis. The 7 Li abundance is, on the other hand, a factor of three lower than predicted by standard Big Bang nucleosynthesis theory. Both problems may be explained if decaying suppersymmetric particles affect the synthesis of light elements in the Big Bang. (orig.)

    The use of robotic surgery for minimally invasive procedures has increased considerably over the last decade. Robotic surgery has potential advantages compared to laparoscopic surgery but also requires new skills. Using virtual reality (VR) simulation to facilitate the acquisition of these new skills could potentially benefit training of robotic surgical skills and also be a crucial step in developing a robotic surgical training curriculum. The study's objective was to establish validity evidence for a simulation-based test for procedural competency for the vaginal cuff closure procedure that can be used in a future simulation-based, mastery learning training curriculum. Eleven novice gynaecological surgeons without prior robotic experience and 11 experienced gynaecological robotic surgeons (> 30 robotic procedures) were recruited. After familiarization with the VR simulator, participants completed the module 'Guided Vaginal Cuff Closure' six times. Validity evidence was investigated for 18 preselected simulator metrics. The internal consistency was assessed using Cronbach's alpha and a composite score was calculated based on metrics with significant discriminative ability between the two groups. Finally, a pass/fail standard was established using the contrasting groups' method. The experienced surgeons significantly outperformed the novice surgeons on 6 of the 18 metrics. The internal consistency was 0.58 (Cronbach's alpha). The experienced surgeons' mean composite score for all six repetitions were significantly better than the novice surgeons' (76.1 vs. 63.0, respectively, p negatives). Our study has gathered validity evidence for a simulation-based test for procedural robotic surgical competency in the vaginal cuff closure procedure and established a credible pass/fail standard for future proficiency-based training.

  1. THE PROBLEM OF THE FINALITY OF WORSHIP AND THE STANDARD THOMISTIC ACCOUNT

    Directory of Open Access Journals (Sweden)

    Francisco J. Romero Carrasquillo

    2013-11-01

    Full Text Available This paper is an attempt to introduce the issue of the finality of religious worship into the analytical Thomist tradition. It aims to develop a response, based on an analysis of St. Thomas Aquinas’s texts, to the following questions: What is the end of worship? Why do we worship God? What benefit does God derive from our worship? Alternatively, perhaps, is it not ourselves, rather than God, who are the beneficiaries of our own worship? The paper aims to develop what may be called the ‘Standard Thomistic Account’ as a solution to this problem. In the first part (II, the paper examines the problem of the finality of worship within the context of Classical Theism. Part II presents the current state of the problem in the contemporary secondary literature concerning this issue. In the third part (III, the paper focuses on Cajetan’s version of the Standard Thomistic Account, and shows in which aspects it is in need of more nuance to be able to portray Aquinas’ complete solution. Finally, Part IV proposes a careful and faithful reading of the texts and lays out the foundations for a new and more nuanced solution to the problem.

    In part I general aspects of the renormalization of a spontaneously broken gauge theory have been introduced. Here, in part II, two-loop renormalization is introduced and discussed within the context of the minimal Standard Model. Therefore, this paper deals with the transition between bare parameters and fields to renormalized ones. The full list of one- and two-loop counterterms is shown and it is proven that, by a suitable extension of the formalism already introduced at the one-loop level, two-point functions suffice in renormalizing the model. The problem of overlapping ultraviolet divergencies is analyzed and it is shown that all counterterms are local and of polynomial nature. The original program of 't Hooft and Veltman is at work. Finite parts are written in a way that allows for a fast and reliable numerical integration with all collinear logarithms extracted analytically. Finite renormalization, the transition between renormalized parameters and physical (pseudo-)observables, are discussed in part III where numerical results, e.g. for the complex poles of the unstable gauge bosons, are shown. An attempt is made to define the running of the electromagnetic coupling constant at the two-loop level. (orig.)

    Full Text Available Objective: The most important factor for accurate treatment of patients with small cell lung carcinoma (SCLC is accuracy of the initial staging. The aim of this study was to determine how often patients, staged as local or local-advanced disease by standard staging procedures (SSPs, would be staged to have a metastatic disease based on the findings of the positron emission tomography–computed tomography (PET-CT scan. Methods: Patients with SCLC who were staged as I, II, or III disease by SSPs (according to the American Joint Committee on Cancer Staging, 7th edition formed the study population. SSPs included computed tomography of chest, abdomen, brain (or magnetic resonance imaging of brain, and bone scintigraphy. These patients were re-staged with 18F-FDG PET-CT scan. Results: Between 2013 and 2015, 27 patients were prospectively studied. Of these patients, 92.5% were male and the median age was 61. Among 27 patients, distant metastasis was detected by PET-CT in 7 (25.9% patients. Two of 7 patients were determined as stage IIIA by SSPs and 5 of 17 patients that were determined as stage IIIB by SSPs were upstaged to metastatic disease by PET-CT. All of the 7 patients had bone metastasis by PET-CT. But bone metastasis could not be detected with bone scintigraphy. Conclusion: PET-CT detected distant metastasis in one quarter of SCLC stage III patients by SSPs. Patients who staged local-advanced SCLC with CT of the chest have to be assessed by PET-CT for extracranial distant metastasis.

  5. Evaluation of the surface free energy of plant surfaces: toward standardizing the procedure.

    Fernández, Victoria; Khayet, Mohamed

    2015-01-01

    Plant surfaces have been found to have a major chemical and physical heterogeneity and play a key protecting role against multiple stress factors. During the last decade, there is a raising interest in examining plant surface properties for the development of biomimetic materials. Contact angle measurement of different liquids is a common tool for characterizing synthetic materials, which is just beginning to be applied to plant surfaces. However, some studies performed with polymers and other materials showed that for the same surface, different surface free energy values may be obtained depending on the number and nature of the test liquids analyzed, materials' properties, and surface free energy calculation methods employed. For 3 rough and 3 rather smooth plant materials, we calculated their surface free energy using 2 or 3 test liquids and 3 different calculation methods. Regardless of the degree of surface roughness, the methods based on 2 test liquids often led to the under- or over-estimation of surface free energies as compared to the results derived from the 3-Liquids method. Given the major chemical and structural diversity of plant surfaces, it is concluded that 3 different liquids must be considered for characterizing materials of unknown physico-chemical properties, which may significantly differ in terms of polar and dispersive interactions. Since there are just few surface free energy data of plant surfaces with the aim of standardizing the calculation procedure and interpretation of the results among for instance, different species, organs, or phenological states, we suggest the use of 3 liquids and the mean surface tension values provided in this study.

  14. Calibration of brachytherapy sources. Guidelines on standardized procedures for the calibration of brachytherapy sources at Secondary Standard Dosimetry Laboratories (SSDLs) and hospitals

    International Nuclear Information System (INIS)

    1999-04-01

    Today, irradiation by brachytherapy is considered an essential part of the treatment for almost all the sites of cancer. With the improved localization techniques and treatment planning systems, it is now possible to have precise and reproducible dose delivery. However, the desired clinical results can only be achieved with a good clinical and dosimetric practice, i.e. with the implementation of a comprehensive quality assurance (QA) programme which includes detailed quality control procedures. As summarized in the present report, accidents in brachytherapy treatments have been caused due to the lack of traceable calibration of the sources, due to the incorrect use of quantities and units, or errors made in the dose calculation procedure. The International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources has established a requirement on the calibration of sources used for medical exposure. For sources used in brachytherapy treatments, a calibration traceable to a standards dosimetry laboratory is required. The present report deals with the calibration of brachytherapy sources and related quality control (QC) measurements, QC of ionization chambers and safety aspects related to the calibration procedures. It does not include safety aspects related to the clinical use of brachytherapy sources, which have been addressed in a recent IAEA publication, IAEA-TECDOC-1040, 'Design and Implementation of a Radiotherapy Programme: Clinical, Medical Physics, Radiation Protection and Safety Aspects'. The procedures recommended in this report yield traceability to internationally accepted standards. It must be realized, however, that a comprehensive QA programme for brachytherapy cannot rest on source calibration alone, but must ensure QC of all the equipment and techniques that are used for the dose delivery to the patient. The present publication incorporates the reports of several consultants meetings in the field of

    Complete resection of the right atrium with conservation of a strip of left atrium around the 4 pulmonary veins followed by direct anastomosis on the vena cava has recently been proposed as an alternative to the standard orthotopic cardiac transplantation described by Shumway and Lower. In order to determine whether this "anatomical" transplantation should now be considered to be the procedure of choice, a prospective randomised study was undertaken in 1991 including 78 patients undergoing 81 cardiac transplantations by one of the two techniques: gr. I: classical transplantation (n = 40), gr. II: "anatomical" transplantation (n = 41). The groups were comparable in age, sex, weight, nature of the underlying cardiac disease and clinical status at the time of transplantation. Similarly, the parameters of the donors were comparable with respect to age, sex, weight and dosage of inotropic drugs at the time of explantation. All patients came of cardiopulmonary bypass with comparable ischaemia time of the graft (gr. I: 136 +/- 46 min; gr. II: 138 +/- 51 min). Immediate return to sinus rhythm occurred in 20 cases in gr. I and 36 cases in gr. II. Atrial arrhythmia persisted in 5 cases in gr. I but in no cases of gr. II. These differences were very significant (p < 0.001). There were 13 early deaths in gr. I and 8 in gr. II. Doppler echocardiography was performed two to three months after transplantation. The right atrial surface was significantly decreased in gr. II (18 +/- 4.7 cm2) compared with gr. I (24 +/- 7 cm2): the same difference was observed for the left atrium (gr. I: 24 +/- 4.5 cm2; gr. II: 20 +/- 5 cm2), p = 0.001. Tricuspid regurgitation was observed in 82% of patients in gr. I compared with 57% in gr. II (p < 0.005). Exercise stress tests during the same period showed no difference in peak oxygen consumption between the groups. Holter ECG monitoring led to permanent pacing in 2 patients of gr. I (5%). The technical simplicity and reduction of postoperative

    2013-12-01

    Over the last decade, many sectors of industrialized society have been rethinking behavior and re-engineering practices to reduce consumption of energy and natural resources. During this time, green and sustainable remediation (GSR) has evolved from conceptual discussions to standard operating procedure for many environmental remediation practitioners. Government agencies and private sector entities have incorporated GSR metrics into their performance criteria and contracting documents. One of the early think tanks for the development of GSR was the Sustainable Remediation Forum (SURF). SURF brings together representatives of government, industry, consultancy, and academia to parse the means and ends of incorporating societal and economic considerations into environmental cleanup projects. Faced with decades-old treatment programs with high energy outputs and no endpoints in sight, a small group of individuals published the institutional knowledge gathered in two years of ad hoc meetings into a 2009 White Paper on sustainable remediation drivers, practices, objectives, and case studies. Since then, SURF has expanded on those introductory topics, publishing its Framework for Integrating Sustainability into Remediation Projects, Guidance for Performing Footprint Analyses and Life-Cycle Assessments for the Remediation Industry, a compendium of metrics, and a call to improve the integration of land remediation and reuse. SURF's research and members have also been instrumental in the development of additional guidance through ASTM International and the Interstate Technology and Regulatory Council. SURF's current efforts focus on water reuse, the international perspective on GSR (continuing the conversations that were the basis of SURF's December 2012 meeting at the National Academy of Sciences in Washington, DC), and ways to capture and evaluate the societal benefits of site remediation. SURF also promotes and supports student chapters at universities across the US

    Soil DNA extraction has become a critical step in describing microbial biodiversity. Historically, ascertaining overarching microbial ecological theories has been hindered as independent studies have used numerous custom and commercial DNA extraction procedures. For that reason, a standardized soil DNA extraction method (ISO-11063) was previously published. However, although this ISO method is suited for molecular tools such as quantitative PCR and community fingerprinting techniques, it has only been optimized for examining soil bacteria. Therefore, the aim of this study was to assess an appropriate soil DNA extraction procedure for examining bacterial, archaeal and fungal diversity in soils of contrasting land-use and physico-chemical properties. Three different procedures were tested: the ISO-11063 standard; a custom procedure (GnS-GII); and a modified ISO procedure (ISOm) which includes a different mechanical lysis step (a FastPrep ®-24 lysis step instead of the recommended bead-beating). The efficacy of each method was first assessed by estimating microbial biomass through total DNA quantification. Then, the abundances and community structure of bacteria, archaea and fungi were determined using real-time PCR and terminal restriction fragment length polymorphism approaches. Results showed that DNA yield was improved with the GnS-GII and ISOm procedures, and fungal community patterns were found to be strongly dependent on the extraction method.

    Pierre Plassart

    Full Text Available Soil DNA extraction has become a critical step in describing microbial biodiversity. Historically, ascertaining overarching microbial ecological theories has been hindered as independent studies have used numerous custom and commercial DNA extraction procedures. For that reason, a standardized soil DNA extraction method (ISO-11063 was previously published. However, although this ISO method is suited for molecular tools such as quantitative PCR and community fingerprinting techniques, it has only been optimized for examining soil bacteria. Therefore, the aim of this study was to assess an appropriate soil DNA extraction procedure for examining bacterial, archaeal and fungal diversity in soils of contrasting land-use and physico-chemical properties. Three different procedures were tested: the ISO-11063 standard; a custom procedure (GnS-GII; and a modified ISO procedure (ISOm which includes a different mechanical lysis step (a FastPrep ®-24 lysis step instead of the recommended bead-beating. The efficacy of each method was first assessed by estimating microbial biomass through total DNA quantification. Then, the abundances and community structure of bacteria, archaea and fungi were determined using real-time PCR and terminal restriction fragment length polymorphism approaches. Results showed that DNA yield was improved with the GnS-GII and ISOm procedures, and fungal community patterns were found to be strongly dependent on the extraction method. The main methodological factor responsible for differences between extraction procedure efficiencies was found to be the soil homogenization step. For integrative studies which aim to examine bacteria, archaea and fungi simultaneously, the ISOm procedure results in higher DNA recovery and better represents microbial communities.

  2. Hydrogen-migration modeling for the EPRI/HEDL standard problems

    A numerical technique has been developed for calculating the full three-dimensional time-dependent Navier-Stokes equations with multiple species transport. The method is a modified form of the Implicit Continuous-fluid Eulerian (ICE) technique to solve the governing equations for low Mach number flows where pressure waves and local variations in compression and expansion are not significant. Large density variations, due to thermal and species concentration gradients, are accounted for without the restrictions of the classical Boussinesq approximation. Calculations of the EPRI/HEDL standard problems verify the feasibility of using this finite-difference technique for analyzing hydrogen dispersion within LWR containments

    2016-09-01

    Full Text Available The paper is devoted to actual problems of the theory and legislation of the modern criminal trial based on provisions of differentiation of a procedural form. Its basic provisions belong also to questions of evidentiary activity. Characteristics of knowledge on criminal case will claim the psychological knowledge and categories included in the mechanism of legal regulation of criminal procedure activity. Key role is allocated for the principle of freedom of an assessment of proofs. In this case the assessment of proofs is carried out on internal belief. Historically it is connected with institute of jury trial and competitiveness. Both the principle of freedom of assessment of proofs, and many other provisions of the procedural theory and the legislation need interpretation and an explanation with use of modern psychological knowledge. At the same time in modern Russian criminal procedure as well as in foreign types of criminal trial the reduced summary or special procedural jurisdictions are actively applied. It means formation of the differentiated model of criminal legal proceedings at which there is a summary process. Simplification of an order of proof on a criminal case through a wide range of exceptions is characteristic of them that constitutes a theoretical and practical problem. At their decision it is necessary to use a modern arsenal of methodology and the theory, including new achievements in the field of psychological knowledge.

  11. Solving the flavour problem in supersymmetric Standard Models with three Higgs families

    International Nuclear Information System (INIS)

    Howl, R.; King, S.F.

    2010-01-01

    We show how a non-Abelian family symmetry Δ 27 can be used to solve the flavour problem of supersymmetric Standard Models containing three Higgs families such as the Exceptional Supersymmetric Standard Model (E 6 SSM). The three 27-dimensional families of the E 6 SSM, including the three families of Higgs fields, transform in a triplet representation of the Δ 27 family symmetry, allowing the family symmetry to commute with a possible high energy E 6 symmetry. The Δ 27 family symmetry here provides a high energy understanding of the Z 2 H symmetry of the E 6 SSM, which solves the flavour changing neutral current problem of the three families of Higgs fields. The main phenomenological predictions of the model are tri-bi-maximal mixing for leptons, two almost degenerate LSPs and two almost degenerate families of colour triplet D-fermions, providing a clear prediction for the LHC. In addition the model predicts PGBs with masses below the TeV scale, and possibly much lighter, which appears to be a quite general and robust prediction of all models based on the D-term vacuum alignment mechanism.

    of malpractice after LN (16; 57%), TE (10; 37%), SP (8; 57%) and AE (2; 100%). There were 16 cases of PTH amongst 27 trials after TE resulting either in death (5) or apallic syndrome (5). Bleeding complications had occurred on the day of surgery in only 2 patients. 16 trials were based on malpractice claims following SP encompassing lack of informed consent (6), anosmia (4), septal perforation (2), frontobasal injury (2) and dry nose (2). Trials after LN procedures were associated exclusively with a lesion of the spinal accessory nerve (28), including lack of informed consent in 19 cases. 49 cases (69%) were decided for the defendant, 22 (31%) were decided for the plaintiff with monetary compensation in 7 of 29 AE/TE-trials, 9 of 28 LN-trials and 6 of 14 SP-trials. Lack of informed consent was not registered for AE/TE but LN (11) and SP (2). Conclusion: Complicated cases following TE, TT, ATE, SP and LN are not systematically collected in Germany. It can be assumed, that not every complicated case is published in the medical literature or law journals and therefore not obtainable for scientific research. Alleged medical malpracice is proven for less than 6% before trial stage. Approximately half of all cases result in a plaintiff verdict or settlement at court. Proper documentation of a thourough counselling, examination, indication, informed consent and follow-up assists the surgeon in litigation. An adequate complication management of PTH is essential, including instructions for the patients/parents, instructions for the medical staff and readily available surgical instruments. Successful outcome of life-threatening PTH is widely based on a proper airway management in an interdisciplinary approach. Electrosurgical tonsillectomy techniques were repeatedly labeled as a risk factor for bleeding complications following TE. Institutions should analyse the individual PTH rate on a yearly basis.

    Nowadays, only closed and proprietary integrated operating room systems (IORS) from big manufacturers are available on the market. Hence, the interconnection of components from third-party vendors is only possible with increased time and costs. In the context of the German Federal Ministry of Education and Research (BMBF)-funded project OR.NET (2012-2016), the open integration of medical devices from different manufacturers was addressed. An integrated operating theater based on the open communication standard IEEE 11073 shall give clinical operators the opportunity to choose medical devices independently of the manufacturer. This approach would be advantageous especially for hospital operators and small- and medium-sized enterprises (SME) of medical devices. Actual standards and concepts regarding technical feasibility and the approval process do not cope with the requirements for a modular integration of medical devices in the operating room (OR), based on an open communication standard. Therefore, innovative approval strategies and corresponding certification and test procedures, which cover actual legal and normative standards, have to be developed in order to support the future risk management and the usability engineering process of open integrated medical devices in the OR. The use of standardized device and service profiles and a three-step testing procedure, including conformity, interoperability and integration tests are described in this paper and shall support the manufacturers to integrate their medical devices without disclosing the medical devices' risk analysis and related confidential expertise or proprietary information.

    Full Text Available Objectives: To compare the efficacy of various standard bariatric surgical procedures using the Bariatric Analysis and Reporting Outcome System (BAROS. Methods: This is a prospective, descriptive analytical study conducted in 2 medical institutions in Saudi Arabia. A total of 270 patients who had different bariatric surgery during the period between March 2010 and December 2012 were included. The data was analyzed and scored against 3 outcomes, excess weight loss, cure or improvement of comorbidities, and quality of life changes. Results: All patients who had different bariatric procedures were included in our study. Seventy-nine (29.3% underwent laparoscopic Roux-en-Y gastric bypass (LRYGBP, 159 (58.9% had laparoscopic sleeve gastrectomy (LSG, and 32 (11.9% had laparoscopic adjustable gastric banding (LAGB. Complete remission of at least one comorbidity was reported in 36% of LRYGBP, 51% in LSG, and 42% in LAGB. While all other patients have improved comorbidities. The BAROS score was good or higher in 78.5% of LRYGBP, 83.6% for the LSG, and 84.4% of LAGB patients. The average excess weight loss was 67.9% in LRYGBP, 75.8% in LSG, and 81.7% LAGB patients. Conclusion: Bariatric surgery provides a substantial reduction in excess weight, improvement and cure of comorbidities, and improvement in quality of life. Standard bariatric procedures have different degrees of outcomes that can be beneficial in selecting appropriate procedure for appropriate indications and patients.

  8. Some problems concerning the application of special procedural rules for small claims litigations

    Directory of Open Access Journals (Sweden)

    Bodiroga Nikola D.

    2015-01-01

    Full Text Available The Serbian 2011 Civil Procedure Code has widened the scope of small claims litigations substantially. According to the Article 468 all monetary claims not exceeding the amount of 3.000 euros shall be treated as small claims. This also applies to the lawsuits where claim is not money but the plaintiff stated that he/she would accept to be paid an amount of money not exceeding the amount of 3.000 euros. Finally, small claims shall also include lawsuits where claim is not money but the value of claim stated by the plaintiff doesn't exceed the amount of 3.000 euros. This means that proceedings started by declaratory or constitutive lawsuits can also be treated as small claims under the Article 468 Civil Procedure Code. In this way the legislator tried to expand the application of small claims provisions to more disputes that would now have to be resolved in summary proceedings. However, the Article 471 of Civil Procedure Code has to be taken into account as well. According to the provision of Article 471 small claims litigations shall be conducted only before lower (basic courts. This rule would mean that no claim that falls into jurisdiction of higher court can be treated as small claim, regardless of the claim value. The colision between the value criteria and the criteria of subject matter jurisdiction leads to legal uncertainty. The parties to the proceedings have to know in advance whether their claim is going to be adjudicated as small claim or pursuant to the provisions governing regular proceedings. Furthermore, the wrong choice of procedural rules made by the first instance court is still not properly sanctioned by the provisions of Civil Procedure Code.

  11. The advantages of using standardized review procedures in certifying type B radioactive material packages

    International Nuclear Information System (INIS)

    Easton, E.P.; Faille, S.

    2004-01-01

    This paper presents the advantages of adopting well-documented standardized review practices for reviewing Type B package designs. The US experience using standardized review plans and guidance has shown them to be a valuable tool in achieving more consistent and efficient package reviews, in training and qualifying technical reviewers, and in enhancing public and industry understanding of the package certification process. In addition, the standardized review practices, as living documents, have proven to be an effective method of incorporating new technical advances into the review process, and have provided a vehicle to make that knowledge widely available to fellow reviewers, the public and industry. Canada implemented a new internal review process in early 2003 to standardize the review of applications for certification of Type B Packages. Based on the similarity of these approaches, the United States and Canada have started discussions on a A North American System for the unilateral approval of Type B (U) packages. This initiative is looking into how each country is currently reviewing transportation package applications to see if agreement can be reached on accepting Type B certifications on a reciprocal basis, i.e., without additional review. Based on the experience in Canada and the United States, the authors believe that the use of standardized review processes, coupled with the knowledge and experience resident in IAEA's Transportation Advisory Material (TS-G-1.1) and series of TECDOCS, could also be used to develop a standard internationally accepted review process that could enhance the acceptance of unilateral approvals for Type B packages

    2014-09-01

    Full Text Available Though there are a number of benefits associated with cellular manufacturing systems, its implementation (identification of part families and corresponding machine groups for real life problems is still a challenging task. To handle the complexity of optimizing multiple objectives and larger size of the problem, most of the researchers in the past two decades or so have focused on developing genetic algorithm (GA based techniques. Recently this trend has shifted from standard GA to hybrid GA (HGA based approaches in the quest for greater effectiveness as far as convergence on to the optimum solution is concerned. In order to prove the point, that HGAs possess better convergence abilities than standard GAs, a methodology, initially based on standard GA and later on hybridized with a local search heuristic (LSH, has been developed during this research. Computational experience shows that HGA maintains its accuracy level with increase in problem size, whereas standard GA looses its effectiveness as the problem size grows.

    Impaired procedural learning has been suggested as a possible cause of developmental dyslexia (DD) and specific language impairment (SLI). This study examined the relationship between measures of verbal and non-verbal implicit and explicit learning and measures of language, literacy and arithmetic attainment in a large sample of 7 to 8-year-old children. Measures of verbal explicit learning were correlated with measures of attainment. In contrast, no relationships between measures of implicit learning and attainment were found. Critically, the reliability of the implicit learning tasks was poor. Our results show that measures of procedural learning, as currently used, are typically unreliable and insensitive to individual differences.

Specifically analyzed is the possibility of participation of judge in deciding on release on parole if he has already acted (had some role in the same case before. The consequences that can be brought by insufficient attention on this issue are as follows: 1 substantive violation of the provisions of criminal procedure, and 2 the conduct of disciplinary proceedings against a judge who should have been disqualified. The second part examines certain provisions of legal acts regulating the matter of conditional release. The enormous significance of parole is that the convict has the possibility to get out after 2/3 of served prison sentence. The scale of these opportunity is clearly visible on the long-term prison sentences. Despite the general tendency towards reducing the prison population, it appears that parole does not and can not achieve the role which it intends. The procedure for release on parole in the case law often acts as a 'sideshow' and the CPC opens the door to discussions about the quality of certain provisions of the procedure for release on parole.

  16. Problems of standardizing and technical regulation in the electric power industry

    A mandatory condition to ensure normal operation of a power system and efficiency in the sector is standardization and legal regulation of technological activities of electric power engineering entities and consumers. Compared to the times of USSR, the present-time technical guidance documents are not mandatory to follow in most cases, being of an advisory nature due to the lack of new ones. During the last five years, the industry has been showing a deterioration of the situation in terms of ensuring reliability and engineering controllability as a result of the dominant impact of short-term market stimuli and the differences in basic technological policies. In absence of clear requirements regarding the engineering aspects of such activities, production operation does not contribute to the preserving of technical integrity of the Russian power system, which leads to the loss of performance capability and controllability and causes disturbances in the power supply to consumers. The result of this problem is a high rate of accident incidence. The dynamics of accidents by the type of equipment is given, indicating a persisting trend of growth in the number of accidents, which are of a systematic nature. Several problematic aspects of engineering activities of electric power engineering entities, requiring standardization and legal regulation are pointed out: in the domestic power system, a large number of power electrotechnical and generating equipment operate along with systems of regulation, which do not comply with the principles and technical rules representing a framework where the Energy System of Russia is built and functioning

  17. Pre-test CFD Calculations for a Bypass Flow Standard Problem

    2011-11-01

    The bypass flow in a prismatic high temperature gas-cooled reactor (HTGR) is the flow that occurs between adjacent graphite blocks. Gaps exist between blocks due to variances in their manufacture and installation and because of the expansion and shrinkage of the blocks from heating and irradiation. Although the temperature of fuel compacts and graphite is sensitive to the presence of bypass flow, there is great uncertainty in the level and effects of the bypass flow. The Next Generation Nuclear Plant (NGNP) program at the Idaho National Laboratory has undertaken to produce experimental data of isothermal bypass flow between three adjacent graphite blocks. These data are intended to provide validation for computational fluid dynamic (CFD) analyses of the bypass flow. Such validation data sets are called Standard Problems in the nuclear safety analysis field. Details of the experimental apparatus as well as several pre-test calculations of the bypass flow are provided. Pre-test calculations are useful in examining the nature of the flow and to see if there are any problems associated with the flow and its measurement. The apparatus is designed to be able to provide three different gap widths in the vertical direction (the direction of the normal coolant flow) and two gap widths in the horizontal direction. It is expected that the vertical bypass flow will range from laminar to transitional to turbulent flow for the different gap widths that will be available.

  4. Documentation for assessment of modal pushover-based scaling procedure for nonlinear response history analysis of "ordinary standard" bridges

    Science.gov (United States)

    Kalkan, Erol; Kwong, Neal S.

    2010-01-01

    The earthquake engineering profession is increasingly utilizing nonlinear response history analyses (RHA) to evaluate seismic performance of existing structures and proposed designs of new structures. One of the main ingredients of nonlinear RHA is a set of ground-motion records representing the expected hazard environment for the structure. When recorded motions do not exist (as is the case for the central United States), or when high-intensity records are needed (as is the case for San Francisco and Los Angeles), ground motions from other tectonically similar regions need to be selected and scaled. The modal-pushover-based scaling (MPS) procedure recently was developed to determine scale factors for a small number of records, such that the scaled records provide accurate and efficient estimates of 'true' median structural responses. The adjective 'accurate' refers to the discrepancy between the benchmark responses and those computed from the MPS procedure. The adjective 'efficient' refers to the record-to-record variability of responses. Herein, the accuracy and efficiency of the MPS procedure are evaluated by applying it to four types of existing 'ordinary standard' bridges typical of reinforced-concrete bridge construction in California. These bridges are the single-bent overpass, multi span bridge, curved-bridge, and skew-bridge. As compared to benchmark analyses of unscaled records using a larger catalog of ground motions, it is demonstrated that the MPS procedure provided an accurate estimate of the engineering demand parameters (EDPs) accompanied by significantly reduced record-to-record variability of the responses. Thus, the MPS procedure is a useful tool for scaling ground motions as input to nonlinear RHAs of 'ordinary standard' bridges.

    This study presents a procedure, called EICS (Enterprise IPPC Compatibility Study) aimed at evaluating, by means of the calculation of three indexes, the compliance of the processes performed in an industrial plant with the guidelines provided by BREFs (BAT References) Documents. In fact, according to European Directive 2010/75/EU (concerning the Integrated Pollution Prevention and Control and repealing European Directive 2008/01/EC), industrial plants must require authorizations to the competent authority stating the conformity of their activity, in order to obtain this conformity they are advised to Best Available Technologies (BAT). The aim of the BATs is to avoid or minimize the impact of an industrial activity on the environment through the prevention of the atmospheric emissions, wastewater discharge and energetic consumption, and the correct waste management thus improving the efficiency of the plant. The procedure shown in the present paper has been tested on several types of industrial plant (cement plants, secondary smelt foundries, paper-mill, and automotive industries as regards their paint lines). In this paper, the application of EICS method to a cement plant is presented: the obtained results highlight a good correlation between the index values and the real situation of the plant.

    The condition of a nuclear material control and accountability system (MC and A) and its individual components, as with any system combining technical elements, documentation and the human factor, may be characterized through an aggregate of values for the various parameters that determine the system's ability to perform. The MC and A system's status may be functioning effectively, marginally or not functioning based on a summary of the values of the individual parameters. This work included a review of the following elements and subsystems or components for a material control and accountability system: (1) MC and A Elements: Information subsystem, Measurement subsystem, NM access subsystem, including a tamper-indicating device (TID) program, and Automated information-gathering subsystem; and (2) Detecting NM Loses Elements: Inventory differences, Shipper/receiver differences, Confirmatory measurements and differences with accounting data, and TID or seal violations. In order to detect the absence or loss of nuclear material there must be appropriate interactions among the elements and their respective subsystems (from the list above). Additionally this work includes a review of the status of regulatory requirements for the MC and A system components and potential criteria that support the evaluation of the performance of the listed components. The listed components had performance testing algorithms and procedures developed that took into consideration the regulatory criteria. The developed MC and A performance-testing procedures were the basis for a pilot Guide for MC and A Performance Testing at the MBAs of SSC RF IPPE.

    Full Text Available Introduction. In the aging process a weakening of the multiple organ systems and endocrine system occur, which in turn, leads to male hormones deficiency – androgens release, including testosterone. It is believed that the year-to-year, women awareness of the menopausal problems increases, however, their knowledge of the consequences of menopause is still insufficient. Unfortunately, only a small percentage of the population is aware that the same problem can also affect men. Male menopause symptoms are still largely an area of social taboo subject, which is not discussed at all or very little. As a consequence, men are not informed, enlightened, and therefore also ready for the changes that are to take place in themselves and their lives.

    In psychological experiments involving facial stimuli, it is of great importance that the basic perceptual or psychological characteristics that are investigated are not confounded by factors such as brightness and contrast, head size, hair cut and color, skin color, and the presence of glasses and earrings. Standardization of facial stimulus materials reduces the effect of these confounding factors. We therefore employed a set of basic image processing techniques to deal with this issue. The processed images depict the faces in grayscale, all at the same size, brightness, and contrast, and confined to an oval mask revealing only the basic features such as the eyes, nose, and mouth. The standardization was successfully applied to four different face databases, consisting of male and female faces and including neutral as well as happy facial expressions. An important advantage of the proposed standardization is that featural as well as configurational information is retained. We also consider the procedure to be a major contribution to the development of a de facto standard for the use of facial stimuli in psychological experiments. Such methodological standardization would allow a better comparison of the results of these studies.

    Full text of publication follows: The computational assessment of reactor core components behavior under accident conditions is impossible without knowledge of the thermal-hydraulic processes occurring in this case. The adequacy of the results obtained using the computer codes to the real processes is verified by carrying out a number of standard problems. In 2000-2003, the fulfillment of three Russian standard problems on WWER core reflooding was arranged using the experiments on full-height electrically heated WWER 37-rod bundle model cooldown in regimes of bottom (SP-1), top (SP-2) and combined (SP-3) reflooding. The representatives from the eight MINATOM's organizations took part in this work, in the course of which the 'blind' and posttest calculations were performed using various versions of the RELAP5, ATHLET, CATHARE, COBRA-TF, TRAP, KORSAR computer codes. The paper presents a brief description of the test facility, test section, test scenarios and conditions as well as the basic results of computational analysis of the experiments. The analysis of the test data revealed a significantly non-one-dimensional nature of cooldown and rewetting of heater rods heated up to a high temperature in a model bundle. This was most pronounced at top and combined reflooding. The verification of the model reflooding computer codes showed that most of computer codes fairly predict the peak rod temperature and the time of bundle cooldown. The exception is provided by the results of calculations with the ATHLET and CATHARE codes. The nature and rate of rewetting front advance in the lower half of the bundle are fairly predicted practically by all computer codes. The disagreement between the calculations and experimental results for the upper half of the bundle is caused by the difficulties of computational simulation of multidimensional effects by 1-D computer codes. In this regard, a quasi-two-dimensional computer code COBRA-TF offers certain advantages. Overall, the closest

    International Standard Problems (ISP) organized by the OECD are defined as comparative exercises in which predictions with different computer codes for a given physical problem are compared with each other and with a carefully controlled experimental study. The main goal of ISP is to increase confidence in the validity and accuracy of analytical tools used in assessing the safety of nuclear installations. In addition, it enables the code user to gain experience and to improve his competence. This paper presents the results and assessment of ISP No. 36, which deals with the early core degradation phase during an unmitigated severe LWR accident in a Russian type VVER. Representatives of 17 organizations participated in the ISP using the codes ATHLET-CD, ICARE2, KESS-III, MELCOR, SCDAP/RELAP5 and RAPTA. Some participants performed several calculations with different codes. As experimental basis the severe fuel damage experiment CORA-W2 was selected. The main phenomena investigated are thermal behavior of fuel rods, onset of temperature escalation, material behavior and hydrogen generation. In general, the calculations give the right tendency of the experimental results for the thermal behavior, the hydrogen generation and, partly, for the material behavior. However, some calculations deviate in important quantities - e.g. some material behavior data - showing remarkable discrepancies between each other and from the experiments. The temperature history of the bundle up to the beginning of significant oxidation was calculated quite well. Deviations seem to be related to the overall heat balance. Since the material behavior of the bundle is to a great extent influenced by the cladding failure criteria a more realistic cladding failure model should be developed at least for the detailed, mechanistic codes. Regarding the material behavior and flow blockage some models for the material interaction as well as for relocation and refreezing requires further improvement.

    The three-dimensionality of space as a physical problem is discussed. Consideration on previous works is done, in which it is showed that the n-dimensional solar system can be stable only for n=3 and, from quantum mechanics, that this is the case also for hydrogen atons. Thus the epistemological consequences of the use of the stability postulate to derive spatial dimensionality is critically reviewed. The distinguished role of Maxwell's eletromagnetic theory in the determination of space dimensionality is stressed. 'Metric versus' 'topological' 'arguments are compared and shown to apply respectively to 'matter' and 'fields'. (G.D.F.) [pt

    1980-08-01

    This paper describes a microspectrophotometric study of blood smears stained by a simple, standardized Romanowsky technique, using only the dyes azure B and cosin. Absorbance spectra are presented for twenty-two classes of cellular object, and for the two dyes in solution, together with tabulations of spectral maxima, and suitable wavelengths for use in automated image processing. The colours of objects stained with azure B/eosin are discussed in terms of absorbance spectra. By a spectral subtraction technique, it is shown that the differential colouration of various cell structures may be explained satisfactorily in terms of the varying proportions of only four dye components. These are the monomers and dimers of azure B and eosin. Polymerization was found to occur both in solution and on binding to biopolymers. A similar analysis of a conventional Romanowsky stain would present much greater difficulties, due to the greater number of dye components, which, however, contribute little to the colours observed.

    KAERI (Korea Atomic Energy Research Institute) has been operating an integral effect test facility, the ATLAS (Advanced Thermal-Hydraulic Test Loop for Accident Simulation) for accident simulations of advanced pressurized water reactors (PWRs). As an integral effect test database for major design basis accidents has been accumulated, a Domestic Standard Problem (DSP) exercise using the ATLAS was proposed in order to transfer the database to domestic nuclear industries and to contribute to improving safety analysis methodology for PWRs. This ATLAS DSP exercise was led by KAERI in collaboration with KINS and it was the first-ever exercise in Korea. This exercise aims at effective utilization of integral effect database obtained from the ATLAS, establishment of cooperation framework among the domestic nuclear industry, better understanding of thermal hydraulic phenomena, and investigation of the possible limitation of the existing best-estimate safety analysis codes. As the first DSP exercise, 100% break scenario of the DVI nozzle was determined by considering its technical importance and by incorporating with comments from participants. Twelve domestic organizations joined this DSP exercise. Finally, ten among the joined organizations submitted their calculation results. They include universities, government, and nuclear industries. This first DSP exercise was performed in an open calculation environment; integral effect test data was open to participants prior to code calculations. This report includes all information of the first DSP-01 exercise as well as comparison results between the calculations and the experimental data

    KAERI (Korea Atomic Energy Research Institute) has been operating an integral effect test facility, the Advanced Thermal-Hydraulic Test Loop for Accident Simulation (ATLAS), for transient and accident simulations of advanced pressurized water reactors (PWRs). Using ATLAS, a high-quality integral effect test database has been established for major design basis accidents of the APR1400 plant. A Domestic Standard Problem (DSP) exercise using the ATLAS database was promoted to transfer the database to domestic nuclear industries and contribute to improving a safety analysis methodology for PWRs. This 2 nd ATLAS DSP (DSP-02) exercise aims at an effective utilization of an integral effect database obtained from ATLAS, the establishment of a cooperation framework among the domestic nuclear industry, a better understanding of the thermal hydraulic phenomena, and an investigation into the possible limitation of the existing best-estimate safety analysis codes. A small break loss of coolant accident with a 6-inch break at the cold leg was determined as a target scenario by considering its technical importance and by incorporating interests from participants. This DSP exercise was performed in an open calculation environment where the integral effect test data was open to participants prior to the code calculations. This paper includes major information of the DSP-02 exercise as well as comparison results between the calculations and the experimental data

    Full Text Available Preparing data from artefact catalogues of previously published German excavation reports, in the project 'Engendering Roman Spaces', required ongoing refinement of data translation and digital manipulation using a variety of software packages. This process included the use of Optical Character Recognition (OCR software, spreadsheets, database and graphics programs, and the final presentation of the data in ArcGIS as an interpretative tool. With each step, a number of challenges were encountered relating to the quality of the data and original cataloguing processes, and the limitations of the software packages being used. Excavation reports of four Roman military sites - the forts of Vetera I, Ellingen, Oberstimm and Rottweil - are used in this article to highlight the range of problems encountered and solutions arrived to resolve them, a process requiring constant revision and refinement.

    Full Text Available The objective of the present study is to standardize the technical variables for preparation and storage of Plasmodium falciparum and of antigen components extracted with the amphoteric detergent Zwittergent. P. falciparum obtained from in vitro culture was stored at different temperatures and for different periods of time. For each variable, antigen components of the parasite were extracted in the presence or absence of protease inhibitors and submitted or not to later dialysis. Products were stored for 15, 30 and 60 days at different temperatures and immunological activity of each extract was determined by SDS-PAGE and ELISA using positive or negative standard sera for the presence of IgG directed to blood stage antigens of P. falciparum. Antigen extracts obtained from parasites stored at -20oC up to 10 days or at -70oC for 2 months presented the best results, showing well-defined bands on SDS-PAGE and Western blots and presenting absorbance values in ELISA that permitted safe differentiation between positive and negative sera.O objetivo deste estudo foi padronizar variáveis técnicas para o armazenamento de Plasmodium falciparum e de seus componentes antigênicos.

    Food safety was identified as a high priority area in the 2001-2005 World Organisation for Animal Health (OIE) Strategic Plan. Member Countries of the OIE considered that the organisation should be more active in issues of public health and consumer protection and that this should include more involvement in the area of diseases or pathogens transmissible through food, whether or not animals are affected by such diseases or pathogens. A permanent Working Group on Animal Production Food Safety was established in 2002 to coordinate the OIE's activities in food safety. The Working Group was requested to focus on food safety measures applicable at farm level and to monitor the ongoing cooperation between the OIE and Codex Alimentarius. More emphasis is now placed on the public health aspects of a disease when OIE standards are developed or revised. For example, the revised chapter on bovine tuberculosis in the Terrestrial Animal Health Code includes food safety recommendations for meat and meat products and for milk and milk products. The revised chapter was approved by the OIE International Committee of Member Countries at their 73rd General Session in May 2005. More chapters will follow, beginning with a chapter addressing bovine brucellosis.

  7. Novel femoral artery terminology: integrating anatomy and clinical procedures leading to standardized intuitive nomenclature.

    The objective of this study is to investigate the terminology of the femoral artery and recommended alternative terminology that satisfies both anatomy and clinical arenas.The femoral artery (FA) is often defined as the continuation of the external iliac artery. Specifically, when the external iliac artery reaches directly beneath the inguinal ligament, it becomes the FA. Currently, Terminologia Anatomica (TA) records the profunda femoris or deep femoral as a terminal branch. Clinicians often use superficial femoral artery (SFA) rather than FA and profunda or deep FA. SFA is actually very deep and well protected for most of its journey. On observation, the terminology in current use is not intuitive. The objective of this study was to investigate the terminology associated with the anatomical and clinical anatomical interpretations of the FA and its terminal branches and to suggest a more appropriate terminology that addresses the points of view of the macro anatomist, as well as that of the clinician. Literature search was conducted regarding the nomenclature of the FA and its terminal branches. Dissection of 89 embalmed cadavers (49F, 40M, ages 47-89) was conducted to analyze the morphology of the FA and its branches. Perusal of the literature revealed a difference in terminology between anatomical and clinical textbooks/atlases/journals regarding the FA and its terminal branch. Our dissections suggested that the FA may be better defined vis-à-vis its relationship to the anterior and posterior compartments of the thigh. A difference in terminology exists between the anatomical and clinical arenas. A need for a standardized terminology is necessary because clinicians and their publishers have not adopted TA. This study suggests that the current FA be considered the common FA and the continuation of the FA, the SFA be renamed the anterior FA and the current profunda (the deep FA) be renamed the posterior FA, respectively. The proposed terminology mirrors the lower

    Multinational experience over many years indicates that all current air decompression schedules for caisson and compressed air tunnel workers are inadequate. All of them, including the Occupational Safety and Health Administration tables, produce dysbaric osteonecrosis. The problem is compounded because decompression sickness (DCS) tends to be underreported. Permanent damage in the form of central nervous system or brain damage may occur in compressed air tunnel workers, as seen on magnetic resonance imaging, in addition to dysbaric osteonecrosis. Oxygen decompression seems to be the only viable method for safely decompressing tunnel workers. Oxygen decompression of tunnel workers has been successfully used in Germany, France, and Brazil. In Germany, only oxygen decompression of compressed air workers is permitted. In our experience, U.S. Navy tables 5 and 6 usually prove adequate to treat DCS in caisson workers despite extremely long exposure times, allowing patients to return to work following treatment for DCS. Tables based on empirical data and not on mathematical formulas seem to be reasonably safe. U.S. Navy Exceptional Exposure Air Decompression tables are compared with caisson tables from the United States and Great Britain.

    Standards of commodity classes of Chinese materia medica is an important way to solve the "Lemons Problem" of traditional Chinese medicine market. Standards of commodity classes are also helpful to rebuild market mechanisms for "high price for good quality". The previous edition of commodity classes standards of Chinese materia medica was made 30 years ago. It is no longer adapted to the market demand. This article researched progress on standards of commodity classes of Chinese materia medica. It considered that biological activity is a better choice than chemical constituents for standards of commodity classes of Chinese materia medica. It is also considered that the key point to set standards of commodity classes is finding the influencing factors between "good quality" and "bad quality". The article also discussed the range of commodity classes of Chinese materia medica, and how to coordinate standards of pharmacopoeia and commodity classes. According to different demands, diversiform standards can be used in commodity classes of Chinese materia medica, but efficacy is considered the most important index of commodity standard. Decoction pieces can be included in standards of commodity classes of Chinese materia medica. The authors also formulated the standards of commodity classes of Notoginseng Radix as an example, and hope this study can make a positive and promotion effect on traditional Chinese medicine market related research.

    KAERI (Korea Atomic Energy Research Institute) has been operating an integral effect test facility, the Advanced Thermal Hydraulic Test Loop for Accident Simulation (ATLAS) for transient and accident simulations of advanced pressurized water reactors (PWRs). By using the ATLAS, a high quality integral effect test database has been established for major design basis accidents of the APR1400. A Domestic Standard Problem (DSP) exercise using the ATLAS database was promoted in order to transfer the database to domestic nuclear industries and to contribute to improving safety analysis methodology for PWRs. This 2nd ATLAS DSP exercise was led by KAERI in collaboration with KINS since the successful completion of the 1st ATLAS DSP in 2009. This exercise aims at effective utilization of integral effect database obtained from the ATLAS, establishment of cooperation framework among the domestic nuclear industry, better understanding of thermal hydraulic phenomena, and investigation of the possible limitation of the existing best estimate safety analysis codes. A small break loss of coolant accident of 6 inch break at the cold leg was determined as a target scenario by considering its technical importance and by incorporating with interests from participants. Twelve domestic organizations joined this DSP 02 exercise. Finally, eleven out of the joined organizations submitted their calculation results, including universities, government, and nuclear industries. This DSP exercise was performed in an open calculation environment where the integral effect test data was open to participants prior to code calculations. This report includes all information of the 2nd ATLAS DSP (DSP 02) exercise as well as comparison results between the calculations and the experimental data

  12. A novel elevated plus-maze procedure to avoid the one-trial tolerance problem

    Full Text Available The elevated plus-maze (EPM test is one of the most commonly used behavioural assays to evaluate anxiety-related behaviour in rodents. It is a rather economic test which usually uses a short (5 min protocol and does not require conditioning of the animals. The critical measure for anxiety is the time spent in the open arms of the maze. A confounding problem of the EPM is the so called one-trial tolerance (OTT, characterised by a marked decrease of open arm exploration in spite of treatment with anxiolytic acting benzodiazepines upon re-exposure to the EPM. This consistent finding is often raised as an evidence for the inappropriateness to re-test rodents in the EPM. However, a reliable re-test paradigm would broaden the usability and effectiveness of this test.Therefore, we tested how a prolongation of the inter-trial interval to 28 days (instead of the usual 24 hours, and an additional change of the testing room would affect the open arm time and other behaviours on the EPM. In two experiments, drug naive Wistar rats were exposed to the EPM on trial 1, and treated intraperitoneally with either vehicle or midazolam (0.25 mg/kg 30 min before trial 2. Then, trial 2 (28 days after trial 1 was carried out in either the same testing room (Exp. 1 or a second unfamiliar room (Exp. 2.Twenty-eight days after trial 1 the open arm time of the rats in the vehicle treated control rats of both experimental groups was comparable to that of the first trial, independent of the testing room. Most importantly, we found that the treatment with the benzodiazepine midazolam had a significantly anxiolytic-like (i.e. increase of open arm time effect in trial 2 only when conducted in the previously unfamiliar testing room (Exp. 2. We suggest that in order to reliably re-test the EPM and to prevent confounding effects due to the OTT, an inter-trial interval of 28 days and a change in testing rooms reinstates anxiolytic-like actions of benzodiazepines

    2016-09-01

    Full Text Available Modeling and optimizing organizational processes, such as the one represented by the Resource-Constrained Project Scheduling Problem (RCPSP, improve outcomes. Based on assumptions and simplification, this model tackles the allocation of resources so that organizations can continue to generate profits and reinvest in future growth. Nonetheless, despite all of the research dedicated to solving the RCPSP and its multi-mode variations, there is no standardized procedure that can guide project management practitioners in their scheduling tasks. This is mainly because many of the proposed approaches are either based on unrealistic/oversimplified scenarios or they propose solution procedures not easily applicable or even feasible in real-life situations. In this study, we solve a more true-to-life and complex model, Multimode RCPSP with minimal and maximal time lags (MRCPSP/max. The complexity of the model solved is presented, and the practicality of the proposed approach is justified depending on only information that is available for every project regardless of its industrial context. The results confirm that it is possible to determine a robust makespan and to calculate an execution time-frame with gaps lower than 11% between their lower and upper bounds. In addition, in many instances, the solved lower bound obtained was equal to the best-known optimum.

    Intestines are used for the production of natural casings as edible sausage containers. Derived from animals (pigs and sheep) experimentally infected with FMDV (initial dosage 10(7.3) PFU/ml, strain O(1Kaufbeuren)), these natural casings were treated with sodium chloride or a phosphate salts/sodium chloride mixture and the residual FMDV titres measured. After storage at about 20 degrees C, no remaining infectivity was found after either treatment, whereas casings stored at 4 degrees C still contained infectivity. Storage of salted casings at about 20 degrees C for 30 days is already part of the Standard Operating Procedures (included in HACCP) of the international casing industry and can therefore be considered as a protective measure for the international trade in natural casings.

    Full Text Available The knowledge of macrofungal diversity associated with Silver Fir forests in Italy is quite scarce. Only a little information is available about macrofungal communities from some Ligurian and Tuscan Silver Fir sites. This study aims to assess the macrofungal diversity of a Silver Fir plantation in Sardinia by the application of a standardized sampling procedure. A total of 606 sporomata were collected and 52 Basidiomycota were identified. The high value of the Shannon Index indicated a considerable level of macrofungal diversity in this plantation. The results were also compared with the diversity indices obtained by a previous 3-years long sampling methodology in the same site. The comparison of the macrofungal diversity values of the Sardinian site with those of the Ligurian Silver Fir forest revealed interesting similarities among natural versus planted coniferous forests.

    Proper decomposition of the sample is one of the basic requirements of the atomic absorption spectroscopic analysis. In the present studies, heavy metals (Cu, Fe, Mn and Zn) were determined in biological samples by designating them in a mixture of nitric acid and perchloric acid. The quantification was made with atomic absorption spectrometry using an air-acetylene flame. The reliability of the procedure used was checked by analysing standard reference materials from NBS and IAEA, such as Rice flour (NBS-SRM-1568), Horse Kidney (IAEA H-8), Mixed Human diet(IAEA H-9), Copepod (IAEA MA-A-1) and fish flesh (IAEA MA-A-2) under identical conditions. A good agreement was observed between determined and the certified values reported by NBS and IAEA. (author)

    The International Standard Problem (ISP) No. 45 is part of the overall ISP program of the OECD/NEA and is dedicated to the behavior of heat-up and delayed reflood of fuel elements in nuclear reactors during a hypothetical accident. ISP-45 is related to the out-of-pile bundle quench experiment QUENCH-06, performed at Forschungszentrum Karlsruhe (FZK), Germany, on December 13, 2000. Special attention was paid to hydrogen production. To assess the ability of severe accident codes to simulate processes during core heat-up and reflood at temperatures above 2000 K, the behavior of the bundle during the whole experiment should be calculated on the basis of the necessary experimental initial and boundary conditions, but without knowing further experimental details. In this so-called blind phase 21 participants from 15 nations contributed with 8 different code systems (ATHLET-CD, ICARE/CATHARE, IMPACT/SAMPSON, GENFLO, MAAP, MELCOR, SCDAPSIM, SCDAP-3D). Additionally, posttest calculations using the in-house version SCDAP/RELAP5 mod3.2.irs are used for comparison. After the end of the blind phase all measured data were made available and the participants were invited to deliver a second calculation, where this knowledge could be used (so-called open phase). In this report, results of the blind calculations are presented, analyzed, and compared to experimental data. During heat-up most results do not deviate significantly from one another, except as a consequence of some obvious user errors, so that a definition of a mainstream is justified. For the quench phase the lack of adequate hydraulic modeling becomes obvious: some participants could not match the observed cool-down rates, others had to use very fine meshes to compensate code deficiencies. To overcome this insufficiency some newly developed reflood models were used in MAAP and MELCOR. In QUENCH-06, oxide layers were thick enough to protect the cladding from melting and failure below 2200 K, so that no massive hydrogen

    Best-estimate thermalhydraulic system codes are widely used to perform safety and licensing analyses of nuclear power plants and also used in the design of advance reactors. Evaluation of the capabilities and the performance of these codes can be accomplished by comparing the code predictions with measured experimental data obtained on different test facilities. In this respect, parallel to other national and international programs, OECD/Nea (OECD Nuclear Energy Agency) Committee on the Safety of Nuclear Installations (CSNI) has promoted, over the last twenty-nine years some forty-eight International Standard Problems (ISPs). These ISPs were performed in different fields as in-vessel thermalhydraulic behaviour, fuel behaviour under accident conditions, fission product release and transport, core/concrete interactions, hydrogen distribution and mixing, containment thermalhydraulic behaviour. 80% of these ISPs were related to the working domain of Principal Working Group no. 2 on Coolant System Behaviour (PWG2). The ISPs have been one of the major PWG2 activities for many years. The individual ISP comparison reports include the analysis and conclusions of the specific ISP exercises. A global review and synthesis on the contribution that ISPs have made to address nuclear reactor safety issues was initiated by CSNI-PWG2 and an overview on the subject of small break LOCA ISP's is given in this paper based on a report prepared by a CSNI-PWG2 writing group. In addition, the relevance of small break LOCA in a PWR with relation to nuclear reactor safety and the reorientation of the reactor safety program after TMI-2 accident, specifically small break LOCA, are shortly summarized. Five small break LOCA related ISP's are considered, since these were used for the assessment of the advanced best-estimate codes. The considered ISP's deal with the phenomenon typical of small break LOCAs in Western design PWRs. The experiments in four integral test facilities, LOBI, SPES, BETHSY

    Full Text Available Chronic low back pain (CLBP is one of the most common medical conditions, ranking as the greatest contributor to global disability and accounting for huge societal costs based on the Global Burden of Disease 2010 study. Large genetic and -omics studies provide a promising avenue for the screening, development and validation of biomarkers useful for personalized diagnosis and treatment (precision medicine. Multicentre studies are needed for such an effort, and a standardized and homogeneous approach is vital for recruitment of large numbers of participants among different centres (clinical and laboratories to obtain robust and reproducible results. To date, no validated standard operating procedures (SOPs for genetic/-omics studies in chronic pain have been developed. In this study, we validated an SOP model that will be used in the multicentre (5 centres retrospective "PainOmics" study, funded by the European Community in the 7th Framework Programme, which aims to develop new biomarkers for CLBP through three different -omics approaches: genomics, glycomics and activomics. The SOPs describe the specific procedures for (1 blood collection, (2 sample processing and storage, (3 shipping details and (4 cross-check testing and validation before assays that all the centres involved in the study have to follow. Multivariate analysis revealed the absolute specificity and homogeneity of the samples collected by the five centres for all genetics, glycomics and activomics analyses. The SOPs used in our multicenter study have been validated. Hence, they could represent an innovative tool for the correct management and collection of reliable samples in other large-omics-based multicenter studies.

    1 H NMR metabolic profiling of urine, serum and plasma has been used to monitor the impact of the pre-analytical steps on the sample quality and stability in order to propose standard operating procedures (SOPs) for deposition in biobanks. We analyzed the quality of serum and plasma samples as a function of the elapsed time (t = 0−4 h) between blood collection and processing and of the time from processing to freezing (up to 24 h). The stability of the urine metabolic profile over time (up to 24 h) at various storage temperatures was monitored as a function of the different pre-analytical treatments like pre-storage centrifugation, filtration, and addition of the bacteriostatic preservative sodium azide. Appreciable changes in the profiles, reflecting changes in the concentration of a number of metabolites, were detected and discussed in terms of chemical and enzymatic reactions for both blood and urine samples. Appropriate procedures for blood derivatives collection and urine preservation/storage that allow maintaining as much as possible the original metabolic profile of the fresh samples emerge, and are proposed as SOPs for biobanking.

    {sup 1}H NMR metabolic profiling of urine, serum and plasma has been used to monitor the impact of the pre-analytical steps on the sample quality and stability in order to propose standard operating procedures (SOPs) for deposition in biobanks. We analyzed the quality of serum and plasma samples as a function of the elapsed time (t = 0-4 h) between blood collection and processing and of the time from processing to freezing (up to 24 h). The stability of the urine metabolic profile over time (up to 24 h) at various storage temperatures was monitored as a function of the different pre-analytical treatments like pre-storage centrifugation, filtration, and addition of the bacteriostatic preservative sodium azide. Appreciable changes in the profiles, reflecting changes in the concentration of a number of metabolites, were detected and discussed in terms of chemical and enzymatic reactions for both blood and urine samples. Appropriate procedures for blood derivatives collection and urine preservation/storage that allow maintaining as much as possible the original metabolic profile of the fresh samples emerge, and are proposed as SOPs for biobanking.

    The honey bee Apis mellifera has emerged as a robust and influential model for the study of classical conditioning thanks to the existence of a powerful Pavlovian conditioning protocol, the olfactory conditioning of the proboscis extension response (PER). In 2011, the olfactory PER conditioning protocol celebrated its 50 years since it was first introduced by Kimihisa Takeda in 1961. In this protocol, individually harnessed honey bees are trained to associate an odor with sucrose solution. The resulting olfactory learning is fast and induces robust olfactory memories that have been characterized at the behavioral, neuronal and molecular levels. Despite the success of this protocol for studying the bases of learning and memory at these different levels, innumerable procedural variants have arisen throughout the years, which render comparative analyses of behavioral performances difficult. Moreover, because even slight variations in conditioning procedures may introduce significant differences in acquisition and retention performances, we revisit olfactory PER conditioning and define here a standardized framework for experiments using this behavioral protocol. To this end, we present and discuss all the methodological steps and details necessary for successful implementation of olfactory PER conditioning. Copyright © 2012 Elsevier B.V.

  13. Physics faculty beliefs and values about the teaching and learning of problem solving. II. Procedures for measurement and analysis

    2007-12-01

    Full Text Available To identify and describe the basis upon which instructors make curricular and pedagogical decisions, we have developed an artifact-based interview and an analysis technique based on multilayered concept maps. The policy capturing technique used in the interview asks instructors to make judgments about concrete instructional artifacts similar to those they likely encounter in their teaching environment. The analysis procedure alternatively employs both an a priori systems view analysis and an emergent categorization to construct a multilayered concept map, which is a hierarchically arranged set of concept maps where child maps include more details than parent maps. Although our goal was to develop a model of physics faculty beliefs about the teaching and learning of problem solving in the context of an introductory calculus-based physics course, the techniques described here are applicable to a variety of situations in which instructors make decisions that influence teaching and learning.

  14. An Interactive Procedure to Solve Multi-Objective Decision-Making Problem: An Improvment to STEM Method

    Full Text Available Decisions in the real-world contexts are often made in the presence of multiple, conflicting, and incommensurate criteria. Multiobjective programming methods such as multiple objective linear programming (MOLP are techniques used to solve such multiple-criteria decision-making (MCDM problems. One of the first interactive procedures to solve MOLP is STEM method. In this paper we try to improve STEM method in a way that we search a point in reduced feasible region whose criterion vector is closest to positive ideal criterion vector and furthest to negative ideal criterion vector. Therefore the presented method tries to increase the rate of satisfactoriness of the obtained solution. Finally, a numerical example for illustration of the new method is given to clarify the main results developed in this paper.

  15. Measurement standards and the general problem of reference points in chemical analysis

    Richter, W.; Dube, G.

    2002-01-01

    Besides the measurement standards available in general metrology in the form of the realisations of the units of measurement, measurement standards of chemical composition are needed for the vast field of chemical measurement (measurements of the chemical composition), because it is the main aim of such measurements to quantify non-isolated substances, often in complicated matrices, to which the 'classical' measurement standards and their lower- level derivatives are not directly applicable. At present, material artefacts as well as standard measurement devices serve as chemical measurement standards. These are measurement standards in the full metrological sense only, however, if they are firmly linked to the SI unit in which the composition represented by the standard is expressed. This requirement has the consequence that only a very restricted number of really reliable chemical measurement standards exist at present. Since it is very difficult and time consuming to increase this number substantially and, on the other hand, reliable reference points are increasingly needed for all kinds of chemical measurements, primary methods of measurement and high-level reference measurements will play an increasingly important role for the establishment of worldwide comparability and hence mutual acceptance of chemical measurement results.

  18. A Finite Element Procedure with Poisson Iteration Method Adopting Pattern Approach Technique for Near-Incompressible Rubber Problems

    Directory of Open Access Journals (Sweden)

    Young-Doo Kwon

    2014-08-01

    Full Text Available A finite element procedure is presented for the analysis of rubber-like hyperelastic materials. The volumetric incompressibility condition of rubber deformation is included in the formulation using the penalty method, while the principle of virtual work is used to derive a nonlinear finite element equation for the large displacement problem that is presented in a total-Lagrangian description. The behavior of rubber deformation is represented by hyperelastic constitutive relations based on a generalized Mooney-Rivlin model. The proposed finite element procedure using analytic differentiation exhibited results that matched very well with those from the well-known commercial packages NISA II and ABAQUS. Furthermore, the convergence of equilibrium iteration is quite slow or frequently fails in the case of near-incompressible rubber. To prevent such phenomenon even for the case that Poisson's ratio is very close to 0.5, Poisson's ratio of 0.49000 is used, first, to get an approximate solution without any difficulty; then the applied load is maintained and Poisson's ratio is increased to 0.49999 following a proposed pattern and adopting a technique of relaxation by monitoring the convergence rate. For a given Poisson ratio near 0.5, with this approach, we could reduce the number of substeps considerably.

    This research is mainly about comparisons of reinforced concrete structure design based on Eurocode 2 and British Standard 8110. The reinforcement concrete element is designed by referring Eurocode 2 (EN1992-1-1) and British Standard 8110 (BS8110-1:1997) for comparing purpose. The work examples of the structural elements has been done in this research to obtain the area of reinforcement required. The differences in procedure, formula and result of area of steel required for the elements based on both of the codes are compared and tabulated. In this research, there are five part of reinforced concrete structure elements are designed which are continuous beams, one way slabs, braced and short column, pile cap, and cantilever retaining wall. From the result acquired, it shows that area of reinforcement required based on EC 2 is lesser than BS 8110 and the dimension required based on BS8110 is larger than EC 2. Meanwhile, the design based on Eurocode 2 came out with more economical structural elements compare to BS 8110 as lesser steel and concrete volume required.

    In judicial terms, a victim refers to any person who has suffered injury arising from an action or omission of an action that constitutes an offence, and the burden of proof lies with the prosecution. A review of Spanish judicial judgements underscored that the lack of evidence of psychological injury in cases of intimate-partner violence (IPV) accounted for approximately 40% of acquittals. Thus, the Spanish standard of proof for the forensic evaluation of psychological injury i.e., the MMPI-2 and the unstructured interview were assessed in order to determine if they met the statutory requirement for the assessment of psychological injury and the differential diagnosis of feigning. The results of the comparison of 51 women victims of IPV with firm convictions against their aggressors, and 54 women mock victims of IPV showed that the F, K, Fb, Fp and Ds scales, and the F-K index discriminated significantly and with medium and large effect sizes, between adjudicated and mock victims. However, the results did not provide a valid decision criterion for forensic settings i.e., false negatives (identifying feigner as honest protocols) were not classified correctly. In conclusion, the standard forensic procedure for the evaluation of psychological injury in cases of IPV did not constitute valid proof for judges who acquitted defendants on the grounds of not proven due to the lack of evidence of psychological injury.

    To increase understanding of how to raise the quality of rheumatology guidelines by reviewing European League Against Rheumatism (EULAR) management recommendations, using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, 10 years after publication of the EULAR standardized operating procedures (SOP) for the production of recommendations. It was hoped that this work could help inform improvements in guideline development by other societies and organizations. The SOP were published in 2004 to ensure the quality of EULAR-endorsed recommendations. We reviewed 27 published EULAR recommendations for management using the AGREE II tool. This provides a framework to assess the quality of guidelines across six broad domains using 23 specific questions. Overall the EULAR recommendations reviewed have been performed to a high standard. There are particular strengths in the methodology and presentation of the guidelines; however, the results indicate areas for development in future recommendations: in particular, stakeholder involvement and applicability of the recommendations. Improvements in quality were evident in recent years, with patient representation in 9 of 15 (60.0%) recommendations published 2010-14 compared with 4 of 12 (33.3%) published 2000-09. In the last 10 years the overall quality of recommendations was good, with standards improving over the decade following publication of the SOP. However, this review process has identified potential areas for improvement, especially in patient representation and provision of implementation tools. The lessons from this work can be applied to the development of rheumatology guidelines by other societies and organizations. © The Author 2015.

    Current external quality assurance schemes have been classified into six categories, according to their ability to verify the degree of standardization of the participating measurement procedures. SKML (Netherlands) is a Category 1 EQA scheme (commutable EQA materials with values assigned by reference methods), whereas SEQC (Spain) is a Category 5 scheme (replicate analyses of non-commutable materials with no values assigned by reference methods). The results obtained by a group of Spanish laboratories participating in a pilot study organized by SKML are examined, with the aim of pointing out the improvements over our current scheme that a Category 1 program could provide. Imprecision and bias are calculated for each analyte and laboratory, and compared with quality specifications derived from biological variation. Of the 26 analytes studied, 9 had results comparable with those from reference methods, and 10 analytes did not have comparable results. The remaining 7 analytes measured did not have available reference method values, and in these cases, comparison with the peer group showed comparable results. The reasons for disagreement in the second group can be summarized as: use of non-standard methods (IFCC without exogenous pyridoxal phosphate for AST and ALT, Jaffé kinetic at low-normal creatinine concentrations and with eGFR); non-commutability of the reference material used to assign values to the routine calibrator (calcium, magnesium and sodium); use of reference materials without established commutability instead of reference methods for AST and GGT, and lack of a systematic effort by manufacturers to harmonize results. Results obtained in this work demonstrate the important role of external quality assurance programs using commutable materials with values assigned by reference methods to correctly monitor the standardization of laboratory tests with consequent minimization of risk to patients.

    1994-01-01

    In this paper we introduce a comprehensive and rigorous robust design procedure to overcome some limitations of the current approaches. A comprehensive approach is general enough to model the two major types of robust design applications, namely, robust design associated with the minimization of the deviation of performance caused by the deviation of noise factors (uncontrollable parameters), and robust design due to the minimization of the deviation of performance caused by the deviation of control factors (design variables). We achieve mathematical rigor by using, as a foundation, principles from the design of experiments and optimization. Specifically, we integrate the Response Surface Method (RSM) with the compromise Decision Support Problem (DSP). Our approach is especially useful for design problems where there are no closed-form solutions and system performance is computationally expensive to evaluate. The design of a solar powered irrigation system is used as an example. Our focus in this paper is on illustrating our approach rather than on the results per se.

    This study evaluates the performance of multivariate calibration transfer methods in a classification context. The spectral variation caused by some experimental conditions can worsen the performance of the initial multivariate classification model but this situation can be solved by implementing standardization methods such as Piecewise Direct Standardization (PDS). This study looks at the adulteration of culinary spices with banned dyes such as Sudan I, II, III and IV. The samples are characterised by their UV-visible spectra and Partial Least Squares-Discriminant Analysis (PLS-DA) is used to discriminate between unadulterated samples and samples adulterated with any of the four Sudan dyes. Two different datasets that need to be standardised are presented. The standardization process yields positive classification results comparable to those obtained from the initial PLS-DA model, in which high classification performance was achieved.

    2015-12-01

    Full Text Available Machine learning is one of the most important subfields of computer science and can be used to solve a variety of interesting artificial intelligence problems. There are different languages, framework and tools to define the data needed to solve machine learning-based problems. However, there is a great number of very diverse alternatives which makes it difficult the intercommunication, portability and re-usability of the definitions, designs or algorithms that any developer may create. In this paper, we take the first step towards a language and a development environment independent of the underlying technologies, allowing developers to design solutions to solve machine learning-based problems in a simple and fast way, automatically generating code for other technologies. That can be considered a transparent bridge among current technologies. We rely on Model-Driven Engineering approach, focusing on the creation of models to abstract the definition of artifacts from the underlying technologies.

    The use of human biological specimens in scientific research is the focus of current international public and professional concern and a major issue in bioethics in general. Brain/Tissue/Bio banks (BTB-banks) are a rapid developing sector; each of these banks acts locally as a steering unit for the establishment of the local Standard Operating Procedures (SOPs) and the legal regulations and ethical guidelines to be followed in the procurement and dissemination of research specimens. An appropriat Code of Conduct is crucial to a successful operation of the banks and the research application they handle. What are we still missing ? (1) Adequate funding for research BTB-banks. (2) Standard evaluation protocls for audit of BTB-bank performance. (3) Internationally accepted SOP's which will facilitate exchange and sharing of specimens and data with the scientific community. (4) Internationally accepted Code of Conduct. In the present paper we review the most pressing organizational, methodological, medico-legal and ethical issues involved in BTB-banking; funding, auditing, procurement, management/handling, dissemination and sharing of specimens, confidentiality and data protection, genetic testing, "financial gain" and safety measures. Taking into consideration the huge variety of the specimens stored in different repositories and the enormous differences in medico-legal systems and ethics regulations in different countries it is strongly recommend that the health-care systems and institutions who host BTB-Banks will put more efforts in getting adequate funding for the infrastructure and daily activities. The BTB-banks should define evaluation protocols, SOPs and their Code of Conduct. This in turn will enable the banks to share the collected specimens and data with the largest possible number of researchers and aim at a maximal scientific spin-off and advance in public health research.

    A total of 177 naturally contaminated water samples were analyzed by membrane filtration according to the Standard Methods for the Examination of Water and Wastewater published by the American Public Health Association. Filters were incubated in parallel on mHPC-agar and 3M Petrifilm Aerobic Count Plates (Petrifilm AC plates) for heterotrophic counts. Fecal coliforms and Escherichia coli were enumerated on mFC-agar and 3M Petrifilm E. coli/Coliform Count Plates (Petrifilm EC plates). Typical colonies on each media type were confirmed following standard procedures. Heterotrophic counts were between 10(3) and 10(4) CFU/mL and the average log10 counts obtained on Petrifilm AC plates were about two-fold lower than on mHPC-agar. Counts for fecal coliforms and E. coli were between 10(2) and 10(3) CFU/mL. Average log10 counts for confirmed fecal coliforms obtained on Petrifilm EC plates were slightly lower than on mFC agar with a correlation coefficient of 0.949. The average log10 counts for confirmed E. coli on Petrifilm EC plates and on mFC agar were statistically not different (P=0.126) with a correlation coefficient of 0.879. Specificity of Petrifilm EC plates and mFC agar was evaluated by comparing typical colony counts with confirmed counts. On mFC agar, counts for typical colonies were by 2 log10 CFU higher than the actual confirmed counts. In contrast, on Petrifilm EC plates typical colony counts were almost identical to confirmed colony counts for both fecal coliforms and E. coli. This comparison illustrates the high specificity of Petrifilm EC plates for enumeration of both fecal coliforms and E. coli in water.

  12. Calibration of photon and beta ray sources used in brachytherapy. Guidelines on standardized procedures at Secondary Standards Dosimetry Laboratories (SSDLs) and hospitals

    International Nuclear Information System (INIS)

    2002-03-01

    It has generally been recognized that international harmonization in radiotherapy dosimetry is essential. Consequently, the IAEA has given much effort to this, for example by publishing a number of reports in the Technical Reports Series (TRS) for external beam dosimetry, most notably TRS-277 and more recently TRS-398. Both of these reports describe in detail the steps to be taken for absorbed dose determination in water and they are often referred to as 'dosimetry protocols'. Similar to TRS-277, it is expected that TRS-398 will be adopted or used as a model by a large number of countries as their national protocol. In 1996, the IAEA established a calibration service for low dose rate (LDR) 137 Cs brachytherapy sources, which is the most widely used source for treatment of gynecological cancer. To further enhance harmonization in brachytherapy dosimetry, the IAEA published in 1999 IAEA-TECDOC-1079 entitled 'Calibration of Brachytherapy Sources. Guidelines on Standardized Procedures for the Calibration of Brachytherapy Sources at Secondary Standard Dosimetry Laboratories (SSDLs) and Hospitals'. The report was well received and was distributed in a large number of copies to the members of the IAEA/WHO network of SSDLs and to medical physicists working with brachytherapy. The present report is an update of the aforementioned TECDOC. Whereas TECDOC-1079 described methods for calibrating brachytherapy sources with photon energies at or above those of 192 Ir, the current report has a wider scope in that it deals with standardization of calibration of all the most commonly used brachytherapy sources, including both photon and beta emitting sources. The latter sources have been in use for a few decades already, but their calibration methods have been unclear. Methods are also described for calibrating sources used in the rapidly growing field of cardiovascular angioplasty. In this application, irradiation of the vessel wall is done in an attempt to prevent restenosis after

The SOP consists of two major sections: Stationary Source Planning and Administration, and Stationary Source Operations These two main sections are further subdivided into twelve subsections which delineate requirements (e.g. maintaining inventories, applying for and maintaining permits, keeping records, reporting and certifying compliance) and assign ownership of processes and responsibilities (e.g. appointing a manager/alternate for each identified stationary air source). In addition, the SOP suggests training that should be provided from operator to commander levels to ensure that all personnel involved with a stationary air source are aware of their responsibilities. Implementation of the SOP should provide for the essential control necessary for installation commanders to eliminate stationary air source non-compliance and to certify compliance in accordance with the Title V Operating Permit requirements. This paper will discuss: the background and purpose for the SOPs content, the twelve subsections of the SOP, the success of implementation at various installations, the relevance or the recommended training, the success of negotiating with various labor unions for SOP implementation and the success of the SOP in reference to its intended purpose.

    Standard operating procedures (SOPs) should improve safety in the operating theatre, but controlled studies evaluating the effect of staff-led implementation are needed. In a controlled interrupted time series, we evaluated three team process measures (compliance with WHO surgical safety checklist, non-technical skills and technical performance) and three clinical outcome measures (length of hospital stay, complications and readmissions) before and after a 3-month staff-led development of SOPs. Process measures were evaluated by direct observation, using Oxford Non-Technical Skills II for non-technical skills and the 'glitch count' for technical performance. All staff in two orthopaedic operating theatres were trained in the principles of SOPs and then assisted to develop standardised procedures. Staff in a control operating theatre underwent the same observations but received no training. The change in difference between active and control groups was compared before and after the intervention using repeated measures analysis of variance. We observed 50 operations before and 55 after the intervention and analysed clinical data on 1022 and 861 operations, respectively. The staff chose to structure their efforts around revising the 'whiteboard' which documented and prompted tasks, rather than directly addressing specific task problems. Although staff preferred and sustained the new system, we found no significant differences in process or outcome measures before/after intervention in the active versus the control group. There was a secular trend towards worse outcomes in the postintervention period, seen in both active and control theatres. SOPs when developed and introduced by frontline staff do not necessarily improve operative processes or outcomes. The inherent tension in improvement work between giving staff ownership of improvement and maintaining control of direction needs to be managed, to ensure staff are engaged but invest energy in appropriate change

  18. A Differential Quadrature Procedure with Regularization of the Dirac-delta Function for Numerical Solution of Moving Load Problem

    Directory of Open Access Journals (Sweden)

    S. A. Eftekhari

    Full Text Available AbstractThe differential quadrature method (DQM is one of the most elegant and efficient methods for the numerical solution of partial differential equations arising in engineering and applied sciences. It is simple to use and also straightforward to implement. However, the DQM is well-known to have some difficulty when applied to partial differential equations involving singular functions like the Dirac-delta function. This is caused by the fact that the Dirac-delta function cannot be directly discretized by the DQM. To overcome this difficulty, this paper presents a simple differential quadrature procedure in which the Dirac-delta function is replaced by regularized smooth functions. By regularizing the Dirac-delta function, such singular function is treated as non-singular functions and can be easily and directly discretized using the DQM. To demonstrate the applicability and reliability of the proposed method, it is applied here to solve some moving load problems of beams and rectangular plates, where the location of the moving load is described by a time-dependent Dirac-delta function. The results generated by the proposed method are compared with analytical and numerical results available in the literature. Numerical results reveal that the proposed method can be used as an efficient tool for dynamic analysis of beam- and plate-type structures traversed by moving dynamic loads.

    Full Text Available Significant problems of the professional ethics principles violation by auditors cause many problems not only in reliability of disclosed audit opinion, but also cause problems of global stakeholders’ mistrust to the audit profession. This generally creates the barriers for ensuring the transparency of mechanisms of disclosure and verification of Ukrainian business data and does not help form appropriate investment climate. The article finds that auditor’s ethical principles should be regulated and organized on all the levels of the audit quality control ensuring. According to the results of this study, the author highlights these four levels (international, national, local, personal and describes the contribution of each level of documents in the organization of the quality control (in part of ethical principles has been. The research proves the system of organizational support for creating ethical principles compliance environment during carrying out audit assignment based on identifying and eliminating threats to auditors’ independence. In this regard, the author proposes the structure and content of organizational and administrative documents, which are the part of the internal audit quality control system.

    2015-01-01

    The JEDEC JESD57 test standard, Procedures for the Measurement of Single-Event Effects in Semiconductor Devices from Heavy-Ion Irradiation, is undergoing its first revision since 1996. In this talk, we place this test standard into context with other relevant radiation test standards to show its importance for single-event effect radiation testing for space applications. We show the range of industry, government, and end-user party involvement in the revision. Finally, we highlight some of the key changes being made and discuss the trade-space in which setting standards must be made to be both useful and broadly adopted.

    The objective of this study was to evaluate the performance of goodness-of-fit testing to detect relevant violations of the assumptions underlying the criticized "standard" two-class latent class model. Often used to obtain sensitivity and specificity estimates for diagnostic tests in the absence of a gold reference standard, this model relies on assuming that diagnostic test errors are independent. When this assumption is violated, accuracy estimates may be biased: goodness-of-fit testing is often used to evaluate the assumption and prevent bias. We investigate the performance of goodness-of-fit testing by Monte Carlo simulation. The simulation scenarios are based on three empirical examples. Goodness-of-fit tests lack power to detect relevant misfit of the standard two-class latent class model at sample sizes that are typically found in empirical diagnostic studies. The goodness-of-fit tests that are based on asymptotic theory are not robust to the sparseness of data. A parametric bootstrap procedure improves the evaluation of goodness of fit in the case of sparse data. Our simulation study suggests that relevant violation of the local independence assumption underlying the standard two-class latent class model may remain undetected in empirical diagnostic studies, potentially leading to biased estimates of sensitivity and specificity.

  4. Lithium in Very Metal-poor Dwarf Stars -- Problems for Standard Big Bang Nucleosynthesis?

    International Nuclear Information System (INIS)

    Lambert, David L.

    2004-01-01

    The standard model of primordial nucleosynthesis by the Big Bang as selected by the WMAP-based estimate of the baryon density (Ωbh2) predicts an abundance of 7Li that is a factor of three greater than the generally reported abundance for stars on the Spite plateau, and an abundance of 6Li that is about a thousand times less than is found for some stars on the plateau. This review discusses and examines these two discrepancies. They can likely be resolved without major surgery on the standard model of the Big Bang. In particular, stars on the Spite plateau may have depleted their surface lithium abundance over their long lifetime from the WMAP-based predicted abundances down to presently observed abundances, and synthesis of 6Li (and 7Li) via α + α fusion reactions may have occurred in the early Galaxy. Yet, there remain fascinating ways in which to remove the two discrepancies involving aspects of a new cosmology, particularly through the introduction of exotic particles

  5. Problems in Standardization of Orthodontic Shear Bond Strength Tests; A Brief Review

    2005-03-01

    Full Text Available Bonding brackets to the enamel surface has gained much popularity today. New adhesive systems have been introduced and marketed and a considerable increase in research regarding bond strength has been published. A considerable amount of these studies deal with shear bond strength of adhesives designed for orthodontic purpose.Previous studies have used variety of test designs. This diversity in test design is due to the fact that there is no standard method for evaluating shear bond strength in orthodontics. Therefore comparison of data obtained from different study is almost impossible.This article tries to briefly discuss the developments occurred in the process of shear bond strength measurement of orthodontic adhesives with an emphasis on the type of test set up and load application.Although the test designs for measuring shear bond strength in orthodontics are still far from ideal, attempts must be made to standardize these tests especially in order to makecomparison of different data easier. It is recommended that test designs be set up in such a manner that better matches with the purpose of the study.

    Errors and accidents, or deviations from standard operating procedures, other policy, or regulations must be documented and reviewed, with corrective actions taken to assure quality performance in a cellular therapy laboratory. Though expectations and guidance for deviation management exist, a description of the framework for the development of such a program is lacking in the literature. Here we describe our deviation management program, which uses a Microsoft Access database and Microsoft Excel to analyze deviations and notable events, facilitating quality assurance (QA) functions and ongoing process improvement. Data is stored in a Microsoft Access database with an assignment to one of six deviation type categories. Deviation events are evaluated for potential impact on patient and product, and impact scores for each are determined using a 0- 4 grading scale. An immediate investigation occurs, and corrective actions are taken to prevent future similar events from taking place. Additionally, deviation data is collectively analyzed on a quarterly basis using Microsoft Excel, to identify recurring events or developing trends. Between January 1, 2001 and December 31, 2001 over 2500 products were processed at our laboratory. During this time period, 335 deviations and notable events occurred, affecting 385 products and/or patients. Deviations within the 'technical error' category were most common (37%). Thirteen percent of deviations had a patient and/or a product impact score > or = 2, a score indicating, at a minimum, potentially affected patient outcome or moderate effect upon product quality. Real-time analysis and quarterly review of deviations using our deviation management program allows for identification and correction of deviations. Monitoring of deviation trends allows for process improvement and overall successful functioning of the QA program in the cell therapy laboratory. Our deviation management program could serve as a model for other laboratories in

    Listeria monocytogenes is a foodborne pathogen responsible for a severe disease known as listeriosis. The European Centre for Disease Prevention and Control (ECDC) coordinates a network of national public health laboratories (NPHLs) in charge of typing clinical strains. In food, it is the European Union Reference Laboratory for L. monocytogenes (EURL Lm), which manages a network of National Reference Laboratories (NRLs). A pulsed-field gel electrophoresis (PFGE) standard operating procedure (EURL SOP) has been used routinely at the EURL Lm since 2007. The EURL Lm has recommended that NRLs use the EURL SOP, whereas the Statens Serum Institut (SSI), under contract for ECDC, requested that NPHLs use Halpins' SOP (HSOP) published in 2010 for the PulseNet USA network. An update of Halpins' SOP (uHSOP) was published in 2013. To facilitate the exchange of profiles among human and food European reference laboratories, it is crucial to ensure that the PFGE profiles obtained with these different SOPs are comparable. The aim here was to compare the EURL SOP with HSOP and uHSOP. The panel comprised 114 well-characterized SSI/EURL strains. All were characterized at the EURL using both the EURL SOP and uHSOP. Seventy of the 114 strains were also characterized at the SSI using HSOP. The EURL SOP and uHSOP produced indistinguishable combined (ApaI/AscI) profiles for the 114 strains tested. The EURL SOP and HSOP produced indistinguishable combined profiles for 69 of the 70 strains tested. One strain displayed for the AscI profile an additional low-intensity band at 184 kbp with HSOP. For this strain, SSI and EUR Lm had already observed the same profile from NPHLs and NRLs. However, this deviation is minor as it accounted for about 1% of all the 114 combined profiles. This study should facilitate the exchange of reproducible PFGE profiles among human and food reference laboratories.

    The minimum volume standards for hospitals in Germany, in force since 2004, provide four exemptions for non-complying hospitals. This study investigates the extent and importance of these exemptions for complex procedures on the oesophagus and pancreas for all non-complying hospitals and for the revised minimum volume regulations in force since the beginning of 2018. Longitudinal, descriptive analyses of data on minimum volume standards and their exemptions for complex procedures on the oesophagus and pancreas, as presented by the hospital quality report cards of the reporting years from 2006 to 2014. For each year and both procedures, about 120 hospitals with some 500 cases report non-compliance with the minimum volume standards. Of these a third report no exemptions (with 180 procedures), a third state emergencies (110), and another third report exemptions due to internal hospital restructuring (210). Ensuring geographical access to care as an exemption is of no importance. After the three year exemption period for installation of a new service line, 20% of the hospitals with procedures on the oesophagus and 30% on the pancreas complied with the minimum volume standards. After the two-year period for staff realignment, the figures were 40 and 50%, respectively. Exemptions do not entirely explain all procedures performed by hospitals not complying with the minimum volume standards. The revised minimum volume regulations' restructuring of exemptions to "emergencies" and "new or renewed service lines" with a two year exemption period, are concordant with the empirical findings of this study.

  11. Vacuum oscillation solution to the solar neutrino problem in standard and nonstandard pictures

    Berezhiani, Z.G.; Rossi, A.

    1995-01-01

    The neutrino long wavelength (just-so) oscillation is reexamined as a solution to the solar neutrino problem. We consider the just-so scenario in various cases: in the framework of the solar models with a relaxed prediction of the boron neutrino flux, as well as in the presence of the nonstandard weak range interactions between neutrino and matter constituents. We show that the fit of the experimental data in the just-so scenario is not very good for any reasonable value of the 8 B neutrino flux, but it substantially improves if the nonstandard τ-neutrino--electron interaction is included. These new interactions could also remove the conflict of the just-so picture with the shape of the SN 1987A neutrino spectrum. Special attention is devoted to the potential of the future real-time solar neutrino detectors such as Super-Kamiokande, SNO, and BOREXINO, which could provide the model-independent tests for the just-so scenario. In particular, these imply a specific deformation of the original solar neutrino energy spectra and time variation of the intermediate energy monochromatic neutrino ( 7 Be and pep) signals

    2007-04-01

    The transfer of a calibration model for determining fiber content in flax stem was accomplished between two near-infrared spectrometers, which are the same brand but which require a standardization. In this paper, three factors, including transfer sample set, spectral type, and standardization method, were investigated to obtain the best standardization result. Twelve standardization files were produced from two sets of the transfer sample (sealed reference standards and a subset of the prediction set), two types of the transfer sample spectra (raw and preprocessed spectra), and three standardization methods (direct standardization (DS), piecewise direct standardization (PDS), and double window piecewise direct standardization (DWPDS)). The efficacy of the model transfer was evaluated based on the root mean square error of prediction, calculated using the independent prediction samples. Results indicated that the standardization using the sealed reference standards was unacceptable, but the standardization using the prediction subset was adequate. The use of the preprocessed spectra of the transfer samples led to the calibration transfers that were successful, especially for the PDS and the DWPDS correction. Finally, standardization using the prediction subset and their preprocessed spectra with DWPDS correction proved to be the best method for transferring the model.

    2010-01-01

    Needs for harmonization of international equipment qualification(EQ) standards have been raised several years due to purchasing problem of nuclear equipment supplied from abroad country. To meet the regulatory requirement of domestic nuclear power plant, manufacturers have to qualify their equipment in accordance with each standard such as IEEE, IEC and RCC-E. Double qualification increase the equipment cost, which result in high construction cost. Even the unification of each standard have been discussed several years, we have got the long way to go yet. Comparison and harmonization of each international standard will give help to purchase the equipment qualified by not endorsed standard. Environmental qualification, seismic qualification and EMI/EMC qualification are major targets for harmonization. Since concern about cable qualification of 60 years life has been raised recently, harmonization of cable qualification standard also needs to be discussed. KEPRI launched a project for harmonization of EQ relative standards such as IEEE, IEC and RCC-E. A study for harmonization of IEEE323 and IEC60780 is known in progress by IEEE committee. In this paper, harmonization of international standards for cable qualification will be discussed. IEEE383 standard is qualification standard for electric cable broadly used in Asian pacific area while IEC60505 is mostly used in European area. Since these two standards have different requirements for environmental qualification of cable, problem can be happened in the plant site when they purchase cable qualified by not endorsed standard. IEEE383-2003 and IEC60505-2004 is the latest version of each standard. Comparison results and recommendations for harmonization of these two standards are introduced herein

Three right-handed neutrinos N {sub i} , a new color triplet Q and a complex SM-singlet scalar σ, whose vacuum expectation value v {sub σ} ∼ 10{sup 11} GeV breaks lepton number and a Peccei-Quinn symmetry simultaneously, are added to the SM. At low energies, the model reduces to the SM, augmented by seesaw generated neutrino masses and mixing, plus the axion. The latter solves the strong CP problem and accounts for the cold dark matter in the Universe. The inflaton is comprised by a mixture of σ and the SM Higgs, and reheating of the Universe after inflation proceeds via the Higgs portal. Baryogenesis occurs via thermal leptogenesis. Thus, five fundamental problems of particle physics and cosmology are solved at one stroke in this unified Standard Model—axion—seesaw—Higgs portal inflation (SMASH) model. It can be probed decisively by upcoming cosmic microwave background and axion dark matter experiments.

    We present in this work a review of the conventional quantization procedure, the proposed by I.E. Segal and a new quantization procedure similar to this one for use in non linear problems. We apply this quantization procedures to different potentials and we obtain the appropriate equations of motion. It is shown that for the linear case the three procedures exposed are equivalent but for the non linear cases we obtain different equations of motion and different energy spectra. (Author) 16 refs

    It is recommended to keep exposure to ionizing radiation as low as reasonably achievable. The aim of this study was to determine whether fluoroscopy-free mapping and ablation using a standardized procedural protocol is feasible in patients undergoing pulmonary vein isolation (PVI). Sixty consecutive patients were analysed: Thirty consecutive patients undergoing PVI using Carto3 were treated using a standardized procedural fluoroscopy protocol with X-ray being disabled after transseptal puncture (Group 1) and compared with a set of previous 30 consecutive patients undergoing PVI without a specific recommendation regarding the use of fluoroscopy (Group 2). The main outcome measures were the feasibility of fluoroscopy-free mapping and ablation, total fluoroscopy time, total dose area product (DAP), and procedure time. Sixty patients (age 60 ± 10 years, 73% male, ejection fraction 0.55 ± 0.09, left atrium 42 ± 8 mm) were included. In Group 1, total fluoroscopy time was 4.2 (2.6-5.6) min and mapping and ablation during PVI without using fluoroscopy was feasible in 29 of 30 patients (97%). In Group 2, total fluoroscopy time was 9.3 (6.4-13.9) min (P fluoroscopy after transseptal puncture using a standardized procedural protocol is feasible in almost all patients and is associated with markedly decreased total fluoroscopy duration and DAP.

    Full Text Available Background: One of the methods used for standard setting is the borderline regression method (BRM. This study aims to assess the reliability of BRM when the pass-fail standard in an objective structured clinical examination (OSCE was calculated by averaging the BRM standards obtained for each station separately. Materials and Methods: In nine stations of the OSCE with direct observation the examiners gave each student a checklist score and a global score. Using a linear regression model for each station, we calculated the checklist score cut-off on the regression equation for the global scale cut-off set at 2. The OSCE pass-fail standard was defined as the average of all station′s standard. To determine the reliability, the root mean square error (RMSE was calculated. The R2 coefficient and the inter-grade discrimination were calculated to assess the quality of OSCE. Results: The mean total test score was 60.78. The OSCE pass-fail standard and its RMSE were 47.37 and 0.55, respectively. The R2 coefficients ranged from 0.44 to 0.79. The inter-grade discrimination score varied greatly among stations. Conclusion: The RMSE of the standard was very small indicating that BRM is a reliable method of setting standard for OSCE, which has the advantage of providing data for quality assurance.

    Since the late 1970s, energy labeling programs and mandatory energy performance standards have been used in many different countries to improve the efficiency levels of major residential and commercial equipment. As more countries and regions launch programs covering a greater range of products that are traded worldwide, greater attention has been given to harmonizing the specific efficiency criteria in these programs and the test methods for measurements. For example, an international compact fluorescent light (CFL) harmonization initiative was launched in 2006 to focus on collaboration between Australia, China, Europe and North America. Given the long history of standards and labeling programs, most major energy-consuming residential appliances and commercial equipment are already covered under minimum energy performance standards (MEPS) and/or energy labels. For these products, such as clothes washers and CFLs, harmonization may still be possible when national MEPS or labeling thresholds are revised. Greater opportunity for harmonization exists in newer energy-consuming products that are not commonly regulated but are under consideration for new standards and labeling programs. This may include commercial products such as water dispensers and vending machines, which are only covered by MEPS or energy labels in a few countries or regions. As China continues to expand its appliance standards and labeling programs and revise existing standards and labels, it is important to learn from recent international experiences with efficiency criteria and test procedures for the same products. Specifically, various types of standards and labeling programs already exist in North America, Europe and throughout Asia for products in China's 2010 standards and labeling programs, namely clothes washers, water dispensers, vending machines and CFLs. This report thus examines similarities and critical differences in energy efficiency values, test procedure specifications and

    The quality management in Nuclear Medicine Services is a requirement of national and international standards. The Brazilian regulatory agency in health surveillance, the Agencia Nacional de Vigilancia Sanitaria (ANVISA), in its Resolucao de Diretoria Colegiada (Collegiate Directory Resolution) no. 38, requires the elaboration of documents describing the technical and clinical routine activities. This study aimed to elaborate, implement and evaluate Standard Operating Procedures (SOPs) for quality control tests and radiological protection activities in the Nuclear Medicine Service of a university hospital. Eighteen SOPs were developed, involving tasks related to dose calibrator, gamma camera, Geiger-Muller detectors and radiological protection activities. The performance of its application was evaluated for a period of six months. It was observed a reduction in 75% of reported operational errors and 42% of the number of reported incidents with contamination by radioactive material. The SOPs were adequate and successful in its application. New procedures involving clinical activities will also be developed and evaluated. (author)

The FAL-ISP 1, aimed to study particle agglomeration, has been simulated with CONTAIN code. The therma hydraulic results obtained have been satisfactory and aerosol ones have been reasonably accurate. However, some discrepancies appeared between predictions and experimental data; these are essentially related to the injection phase of the experiment, where the major influence of input approximations took place. In addition, the rationalization of discrepancies pointed potential data inconsistencies. Some parametric studies showed the results sensitivity to input assumptions concerning aerosol characterization and default values in CONTAIN; in general, they confirmed the suitability of most of the approximations taken.

    Aims: One of the reason for Latarjet procedure failure may be coracoid graft osteolysis. In this study, we aimed to understand if a better compression between the coracoid process and the glenoid, using a mini-plate fixation during the Latarjet procedure, could reduce the amount of coracoid graft osteolysis. Materials and Methods: A computed tomography scan analysis of 26 prospectively followed-up patients was conducted after modified Latarjet procedure using mini-plate fixation technique to determine both the location and the amount of coracoid graft osteolysis in them. We then compared our current results with results from that of our previous study without using mini-plate fixation to determine if there is any statistical significant difference in terms of corcacoid bone graft osteolysis between the two surgical techniques. Results: The most relevant osteolysis was represented by the superficial part of the proximal coracoid, whereas the deep part of the proximal coracoid graft is least involved in osteolysis and has best bone healing. The current study showed a significant difference only for the deep part of the distal coracoid with our previous study (P Latarjet procedure. Conclusion: Our study suggests that there is a significant difference only for the deep part of the distal coracoid in terms of osteolysis. At clinical examination, this difference did not correspond with any clinical findings. Level of Evidence: Level 4. Clinical Relevance: Prospective case series, Treatment study. PMID:23858288

    Informed consent plays a pivotal role in the operative process, and surgeons have an ethical and legal obligation to provide patients with information to allow for shared decision-making. Unfortunately, patient recall after the consent process is frequently poor. This study aims to evaluate the effect of procedure-specific consent forms on patient's recall four weeks after total hip replacement (THR). This is a prospective study using a posttest-only control group design. Sixty adult patients undergoing total hip replacement were allocated to be consented using either the generic or the surgery-specific consent form. Four weeks after surgery, a phone interview was conducted to assess patient's recall of risk of surgical complications. Patient demographic characteristics and educational attainment were similar in both groups. There was a statistically significant increase in the mean number of risks recalled in the study group at 1.43 compared with 0.67 in the control group (P = 0.0131). Consent is a complex process, and obtaining informed consent is far from straightforward. A statistically significant improvement in patient's recall with the use of procedure-specific consent forms was identified, and based on this, we would advocate their use. However, overall patient recall in both groups was poor. We believe that improving the quality of informed consent may require the sum of small gains, and the use of procedure-specific consent forms may aid in this regard.

  2. A proposal of Brazilian Society of Surgical Oncology for standardizing cytoreductive surgery plus hypertermic intraperitoneal chemotherapy procedures in Brazil: pseudomixoma peritonei, appendiceal tumors and malignant peritoneal mesothelioma

    Directory of Open Access Journals (Sweden)

    Thales Paulo Batista

    Full Text Available ABSTRACT Cytoreductive surgery plus hypertermic intraperitoneal chemotherapy has emerged as a major comprehensive treatment of peritoneal malignancies and is currently the standard of care for appendiceal epithelial neoplasms and pseudomyxoma peritonei syndrome as well as malignant peritoneal mesothelioma. Unfortunately, there are some worldwide variations of the cytoreductive surgery and hypertermic intraperitoneal chemotherapy techniques since no single technique has so far demonstrated its superiority over the others. Therefore, standardization of practices might enhance better comparisons between outcomes. In these settings, the Brazilian Society of Surgical Oncology considered it important to present a proposal for standardizing cytoreductive surgery plus hypertermic intraperitoneal chemotherapy procedures in Brazil, with a special focus on producing homogeneous data for the developing Brazilian register for peritoneal surface malignancies.

  3. A Randomized Controlled Trial to Compare e-Feedback Versus "Standard" Face-to-Face Verbal Feedback to Improve the Acquisition of Procedural Skill.

    Al-Jundi, Wissam; Elsharif, Mohamed; Anderson, Melanie; Chan, Phillip; Beard, Jonathan; Nawaz, Shah

    Constructive feedback plays an important role in learning during surgical training. Standard feedback is usually given verbally following direct observation of the procedure by a trained assessor. However, such feedback requires the physical presence of expert faculty members who are usually busy and time-constrained by clinical commitments. We aim to evaluate electronic feedback (e-feedback) after video observation of surgical suturing in comparison with standard face-to-face verbal feedback. A prospective, blinded, randomized controlled trial comparing e-feedback with standard verbal feedback was carried out in February 2015 using a validated pro formas for assessment. The study participants were 38 undergraduate medical students from the University of Sheffield, UK. They were recorded on video performing the procedural skill, completed a self-evaluation form, and received e-feedback on the same day (group 1); observed directly by an assessor, invited to provide verbal self-reflection, and then received standard verbal feedback (group 2). In both groups, the feedback was provided after performing the procedure. The participants returned 2 days later and performed the same skill again. Poststudy questionnaire was used to assess the acceptability of each feedback among the participants. Overall, 19 students in group 1 and 18 students in group 2 completed the study. Although there was a significant improvement in the overall mean score on the second performance of the task for all participants (first performance mean 11.59, second performance mean 15.95; p ≤ 0.0001), there was no difference in the overall mean improvement score between group 1 and group 2 (4.74 and 3.94, respectively; p = 0.49). The mean overall scores for the e-feedback group at baseline recorded by 2 independent investigators showed good agreement (mean overall scores of 12.84 and 11.89; Cronbach α = 0.86). Poststudy questionnaire demonstrated that both e-feedback and standard verbal feedback

    AIM: To assess the level of sedation, patient satisfaction and frequency of unplanned events with conscious sedation for interventional procedures. MATERIALS AND METHODS: One hundred and seventeen patients were assessed prospectively before, during and after procedures. Blood pressure, pulse, oxygen saturation and sedation level were monitored and patients followed up after 24 h. Sedation was scored after drugs were given in accordance with an established protocol. Doses were recorded, as were patients' weight, age and ASA grade and any unplanned events and their management. RESULTS: Seventy-six of the 117 patients (65%) had no unplanned event, 20 (17.1%) became agitated, 15 (12.8%) hypotensive, three (2.6%) hypoxic and three (2.6%) had more than one response. Twelve patients required active management. Fifty-two (44.4%) had a sedation level of {<=}3 (responsive to verbal commands), but 39 (33.3%) reached level 6. Median doses were midazolam 6 mg (1-20 mg) and pethidine 50 mg (12.5-100 mg). Ninety-three percent were satisfied with their sedation. No adverse effects were observed after 24 h. CONCLUSION: Despite using a sedation protocol, unplanned events occurred in 35% (95% CI=27-44%) of patients, although not all required active management. The sedation levels reached in some exceeded guidelines. Unplanned events were commoner with increased sedation level. Patient satisfaction was high and no permanent damage was observed.

  9. A Singlet Extension of the Minimal Supersymmetric Standard Model: Towards a More Natural Solution to the Little Hierarchy Problem

    Energy Technology Data Exchange (ETDEWEB)

    de la Puente, Alejandro [Univ. of Notre Dame, IN (United States)

    2012-05-01

    In this work, I present a generalization of the Next-to-Minimal Supersymmetric Standard Model (NMSSM), with an explicit μ-term and a supersymmetric mass for the singlet superfield, as a route to alleviating the little hierarchy problem of the Minimal Supersymmetric Standard Model (MSSM). I analyze two limiting cases of the model, characterized by the size of the supersymmetric mass for the singlet superfield. The small and large limits of this mass parameter are studied, and I find that I can generate masses for the lightest neutral Higgs boson up to 140 GeV with top squarks below the TeV scale, all couplings perturbative up to the gauge unification scale, and with no need to fine tune parameters in the scalar potential. This model, which I call the S-MSSM is also embedded in a gauge-mediated supersymmetry breaking scheme. I find that even with a minimal embedding of the S-MSSM into a gauge mediated scheme, the mass for the lightest Higgs boson can easily be above 114 GeV, while keeping the top squarks below the TeV scale. Furthermore, I also study the forward-backward asymmetry in the t¯t system within the framework of the S-MSSM. For this purpose, non-renormalizable couplings between the first and third generation of quarks to scalars are introduced. The two limiting cases of the S-MSSM, characterized by the size of the supersymmetric mass for the singlet superfield is analyzed, and I find that in the region of small singlet supersymmetric mass a large asymmetry can be obtained while being consistent with constraints arising from flavor physics, quark masses and top quark decays.

    1979-01-01

    The authors examine, from the points of view of the ICRP recommendations and of national and international standards, radiation protection problems posed by persons simultaneously engaged in professional activities involving radiation hazards in more than one place. The consequences of this type of situation, for the radiological protection classification of workers and for the evaluation and recording of doses received, are described in detail. In order to ensure proper monitoring of doses, agreements must be reached in advance between those in charge of the different areas of activity. Three cases seem to be of particular relevance: (a) that of workers who, while working for a single employer, perform in more than one place activities in which they are exposed to ionizing radiation (scientists working at different research centres, employees of companies specialized in the nuclear field, including the use of isotopes, accelerators, etc.); (b) that of workers who are engaged by more than one employer and are exposed to ionizing radiations as a result of their activities at different establishments (a special case is that of doctors who are radiologists or specialists in some other branch of nuclear medicine and work both as employees and independently in their own practices); and (c) that of employees of outside organizations not directly concerned with nuclear activities who are only exposed to ionizing radiation when called upon to work in establishments possessing sources of radiation. Finally, the authors suggest some ways of solving these problems - though they are rather difficult to define objectively (for example the case of medical practioners). (author)

    2013-05-01

    Present study provides a novel MATLAB-based parameter estimation procedure for individual assessment of hepatic insulin degradation (HID) process from standard frequently-sampled intravenous glucose tolerance test (FSIGTT) data. Direct access to the source code, offered by MATLAB, enabled us to design an optimization procedure based on the alternating use of Gauss-Newton's and Levenberg-Marquardt's algorithms, which assures the full convergence of the process and the containment of computational time. Reliability was tested by direct comparison with the application, in eighteen non-diabetic subjects, of well-known kinetic analysis software package SAAM II, and by application on different data. Agreement between MATLAB and SAAM II was warranted by intraclass correlation coefficients ≥0.73; no significant differences between corresponding mean parameter estimates and prediction of HID rate; and consistent residual analysis. Moreover, MATLAB optimization procedure resulted in a significant 51% reduction of CV% for the worst-estimated parameter by SAAM II and in maintaining all model-parameter CV% MATLAB-based procedure was suggested as a suitable tool for the individual assessment of HID process.

    2016-03-16

    This document identifies scope and some general procedural steps for performing Remediated Nitrate Salt (RNS) Surrogate Formulation and Testing. This Test Plan describes the requirements, responsibilities, and process for preparing and testing a range of chemical surrogates intended to mimic the energetic response of waste created during processing of legacy nitrate salts. The surrogates developed are expected to bound1 the thermal and mechanical sensitivity of such waste, allowing for the development of process parameters required to minimize the risk to worker and public when processing this waste. Such parameters will be based on the worst-case kinetic parameters as derived from APTAC measurements as well as the development of controls to mitigate sensitivities that may exist due to friction, impact, and spark. This Test Plan will define the scope and technical approach for activities that implement Quality Assurance requirements relevant to formulation and testing.

    During a severe accident in a Pressurized Water Reactor (PWR), the formation of a combustible gas mixture in the complex geometry of the reactor depends on the understanding of hydrogen production, the complex 3D thermal-hydraulics flow due to gas/steam injection, natural convection, heat transfer by condensation on walls and effect of mitigation devices. Numerical simulation of such flows may be performed either by Lumped Parameter (LP) or by Computational Fluid Dynamics (CFD) codes. Advantages and drawbacks of LP and CFD codes are well-known. LP codes are mainly developed for full size containment analysis but they need improvements, especially since they are not able to accurately predict the local gas mixing within the containment. CFD codes require a process of validation on well-instrumented experimental data before they can be used with a high degree of confidence. The MISTRA coupled effect test facility has been built at CEA to fulfil this validation objective: with numerous measurement points in the gaseous volume - temperature, gas concentration, velocity and turbulence - and with well controlled boundary conditions. As illustration of both experimental and simulation areas of this topic, a recent example in the use of MISTRA test data is presented for the case of the International Standard Problem ISP47. The proposed experimental work in the MISTRA facility provides essential data to fill the gaps in the modelling/validation of computational tools. (author)

    Full Text Available The objective of the study was to develop a novel procedure to increase self-efficacy for exercise. Gains in one’s ability to resolve day-to-day obstacles for entering an exercise routine were expected to cause an increase in self-efficacy for exercise. Fifty-five sedentary participants (did not exercise regularly for at least 4 months prior to the study who expressed an intention to exercise in the near future were selected for the study. Participants were randomly assigned to one of three conditions: 1 an Experimental Group in which they received a problem-solving training session to learn new strategies for solving day-to-day obstacles that interfere with exercise, 2 a Control Group with Problem Solving Training which received a problem solving training session focused on a typical day-to-day problem unrelated to exercise, or 3 a Control Group which did not receive any problem-solving training. Assessment of obstacles to exercise and perceived self-efficacy for exercise were conducted at baseline; perceived self-efficacy for exercise was reassessed post-intervention (one week later. No differences in perceived challenges posed by obstacles to exercise or self-efficacy for exercise were observed across groups at baseline. The Experimental Group reported greater improvement in self-efficacy for exercise compared to the Control Group with Training (p < 0.01 and the Control Group (p < 0.01. Results of this study suggest that a novel procedure that focuses on removing obstacles to intended planned fitness activities is effective in increasing self-efficacy to engage in exercise among sedentary adults. Implications of these findings for use in applied settings and treatment studies are discussed.

    In the boreholes projects, the minimization of the instability problems is extreme importance. In the boreholes instability analysis, two failure mechanisms are generally considered, namely, failure due to either tensile or compressive stresses. Considering these mechanisms, the correct determination of the lower and upper limits of pressures, generated by the drilling fluid in the walls of the boreholes, is an alternative for minimization of the instability problems. The mechanisms of compression or tensile failure can be described in terms of mechanical and fluid flow responses of the transient fluid mechanical coupling problem. This paper proposes a numerical procedure, using finite elements, of the coupled fluid mechanical processes, for automatically determining the lower and upper limits of pressures on the walls of borehole, to ensure, according assumptions and criteria of failure pre-established, the stability of the same. The automatic obtaining those values has the purpose of replace the approximate obtaining by trial and error processes. A hypothetical example of application is show, and from this, inferred considerations about the proposed procedure. (author)

  20. The misinterpretation of the standard error of measurement in medical education: a primer on the problems, pitfalls and peculiarities of the three different standard errors of measurement.

    Science.gov (United States)

    McManus, I C

    2012-01-01

    In high-stakes assessments in medical education, such as final undergraduate examinations and postgraduate assessments, an attempt is frequently made to set confidence limits on the probable true score of a candidate. Typically, this is carried out using what is referred to as the standard error of measurement (SEM). However, it is often the case that the wrong formula is applied, there actually being three different formulae for use in different situations. To explain and clarify the calculation of the SEM, and differentiate three separate standard errors, which here are called the standard error of measurement (SEmeas), the standard error of estimation (SEest) and the standard error of prediction (SEpred). Most accounts describe the calculation of SEmeas. For most purposes, though, what is required is the standard error of estimation (SEest), which has to be applied not to a candidate's actual score but to their estimated true score after taking into account the regression to the mean that occurs due to the unreliability of an assessment. A third formula, the standard error of prediction (SEpred) is less commonly used in medical education, but is useful in situations such as counselling, where one needs to predict a future actual score on an examination from a previous actual score on the same examination. The various formulae can produce predictions that differ quite substantially, particularly when reliability is not particularly high, and the mark in question is far removed from the average performance of candidates. That can have important, unintended consequences, particularly in a medico-legal context.

    Guidelines advise periprocedural saline hydration for prevention of contrast induced-acute kidney injury (CI-AKI). We analysed whether 1-hour sodium bicarbonate hydration administered solely prior to intra-arterial contrast exposure is non-inferior to standard periprocedural saline hydration in chronic kidney disease (CKD) patients undergoing elective cardiovascular diagnostic or interventional contrast procedures. We performed an open-label multicentre non-inferiority trial between 2011-2014. Patients were randomized to 1 hour pre-procedure sodium bicarbonate hydration (250 ml 1.4%, N = 168) or 4-12 hours saline hydration (1000 ml 0.9%, N = 165) prior to and following contrast administration (2000 ml of saline total). Primary outcome was the relative serum creatinine increase (%) 48-96 hours post contrast exposure. Secondary outcomes were: incidence of CI-AKI (serum creatinine increase>25% or >44μmol/L), recovery of renal function, the need for dialysis, and hospital costs within two months follow-up. Mean relative creatinine increase was 3.1% (95%CI 0.9 to 5.2%) in the bicarbonate and 1.1% (95%CI -1.2 to 3.5%) in the saline arm, mean difference 1.9% (95%CI -1.2 to 5.1%, p-non-inferiority sodium bicarbonate and 12 (7.5%) to saline (p = 0.79). Renal function did not fully recover in 40.0% and 44.4% of CI-AKI patients, respectively (p = 0.84). No patient required dialysis. Mean costs for preventive hydration and clinical preparation for the contrast procedure were $1158 for sodium bicarbonate vs. $1561 for saline (p sodium bicarbonate prior to elective cardiovascular diagnostic or therapeutic contrast procedures is non-inferior to standard periprocedural saline hydration in CKD patients with respect to renal safety and results in considerable healthcare savings.

  3. Balancing energy conservation and occupant needs in ventilation rate standards for Big Box stores and other commercial buildings in California. Issues related to the ASHRAE 62.1 Indoor Air Quality Procedure

    This report considers the question of whether the California Energy Commission should incorporate the ASHRAE 62.1 ventilation standard into the Title 24 ventilation rate (VR) standards, thus allowing buildings to follow the Indoor Air Quality Procedure. This, in contrast to the current prescriptive standard, allows the option of using ventilation rate as one of several strategies, which might include source reduction and air cleaning, to meet specified targets of indoor air concentrations and occupant acceptability. The research findings reviewed in this report suggest that a revised approach to a ventilation standard for commercial buildings is necessary, because the current prescriptive ASHRAE 62.1 Ventilation Rate Procedure (VRP) apparently does not provide occupants with either sufficiently acceptable or sufficiently healthprotective air quality. One possible solution would be a dramatic increase in the minimum ventilation rates (VRs) prescribed by a VRP. This solution, however, is not feasible for at least three reasons: the current need to reduce energy use rather than increase it further, the problem of polluted outdoor air in many cities, and the apparent limited ability of increasing VRs to reduce all indoor airborne contaminants of concern (per Hodgson (2003)). Any feasible solution is thus likely to include methods of pollutant reduction other than increased outdoor air ventilation; e.g., source reduction or air cleaning. The alternative 62.1 Indoor Air Quality Procedure (IAQP) offers multiple possible benefits in this direction over the VRP, but seems too limited by insufficient specifications and inadequate available data to provide adequate protection for occupants. Ventilation system designers rarely choose to use it, finding it too arbitrary and requiring use of much non-engineering judgment and information that is not readily available. This report suggests strategies to revise the current ASHRAE IAQP to reduce its current limitations. These

    The edge-smooth finite element method (ES-FEM) can improve the computational accuracy of triangular shell elements and the mesh partition efficiency of complex models. In this paper, an approach is developed to perform explicit finite element simulations of contact-impact problems with a graphical processing unit (GPU) using a special edge-smooth triangular shell element based on ES-FEM. Of critical importance for this problem is achieving finer-grained parallelism to enable efficient data loading and to minimize communication between the device and host. Four kinds of parallel strategies are then developed to efficiently solve these ES-FEM based shell element formulas, and various optimization methods are adopted to ensure aligned memory access. Special focus is dedicated to developing an approach for the parallel construction of edge systems. A parallel hierarchy-territory contact-searching algorithm (HITA) and a parallel penalty function calculation method are embedded in this parallel explicit algorithm. Finally, the program flow is well designed, and a GPU-based simulation system is developed, using Nvidia's CUDA. Several numerical examples are presented to illustrate the high quality of the results obtained with the proposed methods. In addition, the GPU-based parallel computation is shown to significantly reduce the computing time.

    To develop a protocol for obtaining autologous platelet rich plasma in healthy individuals and to determine the concentration of five major growth factors before platelet activation. This protocol could be integrated into the guidelines of good clinical practice and research in regenerative medicine. Platelet rich plasma was isolated by centrifugation from 38 healthy men and 42 women ranging from 18 to 59 years old. The platelet count and quantification of growth factors were analyzed in eighty samples, stratified for age and gender of the donor. Analyses were performed using parametric the t-test or Pearson's analysis for non-parametric distribution. P platelet counts from 1.6 to 4.9 times (mean = 2.8). There was no correlation between platelet concentration and the level of the following growth factors: VEGF-D (r = 0.009, p = 0.4105), VEGF-A (r = 0.0068, p = 0.953), PDGF subunit AA (p = 0.3618; r = 0.1047), PDGF-BB (p = 0.5936; r = 0.6095). In the same way, there was no correlation between donor gender and growth factor concentrations. Only TGF-β concentration was correlated to platelet concentration (r = 0.3163, p = 0.0175). The procedure used allowed us to make preparations rich in platelets, low in leukocytes and red blood cells, and sterile. Our results showed biological variations in content of growth factors in PRP. The factors influencing these results should be further studied.

    In the event of a major radiological emergency, the U.S. Federal Radiological Emergency Response Plan authorises the creation of the Federal Radiological Monitoring and Assessment Center (FRMAC). The FRMAC is established to co-ordinate the Federal off-site monitoring and assessment activities, and is comprised of representatives from several Federal agencies and Department of Energy contractors who provide assistance to the state(s) and Lead Federal Agency. The Evaluation and Assessment (E and A) Division of the FRMAC is responsible for receiving, storing, and interpreting environmental surveillance data to estimate the potential health consequences to the population in the vicinity of the accident site. The E and A Division has commissioned the preparation of a methodology and procedures manual which will result in a consistent approach by Division members in carrying out their duties. The first edition of this manual is nearing completion. In this paper, a brief review of the structure of the FRMAC is presented, with emphasis on the E and A Division. The contents of the E and A manual are briefly described, as are future plans for its expansion. (author)

    The CSNI International Standard Problems have been one of the key activities of the CSNI thermal hydraulics groups during the last 25 years. After recalling the way the international standard problems were initiated in the late 1970 years -they were called at that time CSNI LOCA Standard Problem- the process which has led to make from the ISPs a full CSNI activity, is described. Rules have been defined which formalized the way experimental results were provided and the way the comparison exercise were performed. The long series of ISPs from 1975 up to nowadays is described, explaining the different trends in the ISPs choices. The findings which have been obtained are reviewed on both technical and programmatic aspects.

    Various chemical mutagens and gamma radiation have been used on single dormant eyes and true seeds with a view to finding effective mutagenic treatment for the induction of day-length neutral mutants in potato using an effective screening technique for the isolation of day-length neutral mutants. Sodium meta bisulphite (SMS) was found to be an efficient mutagen in inducing mutations for this trait in true seeds although the same concentrations, when used for treating the single tuber eyes proved lethal. Pre-soaking the seeds for 24 hrs prior to treatment with 0.0025M SMS gave highest frequency of the mutants followed by 48 hrs presoaking, indicating a sensitive stage during the cell cycle in true seeds. Other mutagen treatments gave different frequencies of mutations. The highest frequency of day-length neutral mutants was observed when seeds irradiated with 40 Kr of gamma radiation were treated with 0.05M hydrazinium dichloride solution. Screening procedures have also been standardised with the development of synethetic media for the isolation of biochemical mutants at the true seed level. Initial efforts have yielded mutants resistant to LD 100 doses of ethionine. Another aspect of the study was to develop a proper potato callus culture technique. A medium has been developed to produce and maintain callus from potato leaf strips. Efforts on the regeneration of shoot and roots from callus, have so far lead to differentiation of callus to form roots. The ultimate aim of these studies is to develop plantlets from single cell which would form the units of mutation induction and isolation. (author)

    Full Text Available Bone marrow sampling remains essential in the evaluation of hematopoietic and many non-hematopoietic disorders. One common limitation to these procedures is the discomfort experienced by patients. To address whether a Powered biopsy system could reduce discomfort while providing equivalent or better results, we performed a randomized trial in adult volunteers. Twenty-six subjects underwent bilateral biopsies with each device. Core samples were obtained in 66.7% of Manual insertions; 100% of Powered insertions (P=0.002. Initial mean biopsy core lengths were 11.1±4.5 mm for the Manual device; 17.0±6.8 mm for the Powered device (P<0.005. Pathology assessment for the Manual device showed a mean length of 6.1±5.6 mm, width of 1.0±0.7 mm, and volume of 11.0±10.8 mm3. Powered device measurements were mean length of 15.3±6.1 mm, width of 2.0±0.3 mm, and volume of 49.1±21.5 mm3 (P<0.001. The mean time to core ejection was 86 seconds for Manual device; 47 seconds for the Powered device (P<0.001. The mean second look overall pain score was 33.3 for the Manual device; 20.9 for the Powered (P=0.039. We conclude that the Powered biopsy device produces superior sized specimens, with less overall pain, in less time.

    Animal welfare was identified as a priority for the World Organisation for Animal Health (OIE) in the 2001-2005 OIE Strategic Plan. Member Countries recognised that, as animal protection is a complex, multi-faceted public policy issue which includes important scientific, ethical, economic and political dimensions, the OIE needed to develop a detailed vision and strategy incorporating and balancing these dimensions. A permanent working group on animal welfare was established in order to provide guidance to the OIE in its work on the development of science-based standards and guidelines. The Working Group decided to give priority to the welfare of animals used in agriculture and aquaculture, and that, within those groups, the topics of transportation, slaughter for human consumption and killing for disease control purposes would be addressed first. Some guiding principles were approved by the International Committee of OIE Member Countries during the 72nd General Session in May 2004, and these have been followed by four specific guidelines on the priority topics listed above.

    Two techniques of certification of standard specimens of plant (SSP) are considered. The first technique-comparison with initial SS-metallic uranium NBS-960 - is used for certification of uranium. protoxide-oxide. The mass part of the sum of analyzed impurities in prepared initial SS is (8.4+-0.8)x10 -3 %. For certification according to mass uranium part the method of gravimetric potentiometric titration with semiautomatic titrator is used; the mean quadratic deviation of the method is s=0.0002-0.0003, certified value of uranium mass part in SSP (taking account of the error of initial SS) is (84.80+-0.02)%. The second technigue - a simplified circular experiment - is used for certification of SSP-nitric acid solution of neptunium as to Np mass part. Coulometry at controlled potential and coulometry at controlled current and two variants of potentiometric titration are used as certification methods of analysis. Relative mean quadratic deviations of the methods are ssub(r)=0.0014-0.0023. When calculating total error of certified value of neptunium mass part constituents of both accidental and unremoved systematic errors of the methods were included. The final certification result of SSP is (5.707+-0.018)% [ru

    In December 2007, the European Society of Intensive Care Medicine established a Task Force to develop standard operating procedures (SOPs) for operating intensive care units (ICU) during an influenza epidemic or mass disaster. To provide direction for health care professionals in the preparation and management of emergency ICU situations during an influenza epidemic or mass disaster, standardize activities, and promote coordination and communication among the medical teams. Based on a literature review and contributions of content experts, a list of essential categories for managing emergency situations in the ICU were identified. Based on three cycles of a modified Delphi process, consensus was achieved regarding the categories. A primary author along with an expert group drafted SOPs for each category. Based on the Delphi cycles, the following key topics were found to be important for emergency preparedness: triage, infrastructure, essential equipment, manpower, protection of staff and patients, medical procedures, hospital policy, coordination and collaboration with interface units, registration and reporting, administrative policies and education. The draft SOPs serve as benchmarks for emergency preparedness and response of ICUs to emergencies or outbreak of pandemics.

    The dilution biochemical oxygen demand (BOD) test has widespread application for design and operation of wastewater treatment processes, evaluating the quality of natural waters, and assessing the effect of wastewater discharges on these waters. While standardization of the BOD-measuring method has become of prime importance in maintaining dependable data acquisition, changes are made as needed in response to questions raised by analysts and to accommodate new applications. The purpose of this article is to describe changes that have been incorporated in the 20th and 21st editions of Standard Methods for the Examination of Water and Wastewater (APHA et al., 1998 and 2004). These changes include changes in text format to clarify the procedural steps, allowance for use of bottle sizes ranging from 60 mL or larger, improvements in quality-control procedures, and improvements in the method of calculating BOD. Other changes include allowance for the use of allylthiourea for nitrification inhibition and broadening the source of seed that can be used for inoculation of BOD samples.

    The quality assurance of care and patient safety, with increasing cost pressure and performance levels is of major importance in the high-risk and high cost area of the operating room (OR). Standard operating procedures (SOP) are an established tool for structuring and standardization of the clinical treatment pathways and show multiple benefits for quality assurance and process optimization. An internal project was initiated in the department of anesthesiology and a continuous improvement process was carried out to build up a comprehensive SOP library. In the first step the spectrum of procedures in anesthesiology was transferred to PDF-based SOPs. The further development to an app-based SOP library (Aesculapp) was due to the high resource expenditure for the administration and maintenance of the large PDF-based SOP collection and to deficits in the mobile availability. The next developmental stage, the SOP healthcare information assistant (SOPHIA) included a simplified and advanced update feature, an archive feature previously missing and notably the possibility to share the SOP library with other departments including the option to adapt each SOP to the individual situation. A survey of the personnel showed that the app-based allocation of SOPs (Aesculapp, SOPHIA) had a higher acceptance than the PDF-based developmental stage SOP form. The SOP management system SOPHIA combines the benefits of the forerunner version Aesculapp with improved options for intradepartmental maintenance and administration of the SOPs and the possibility of an export and editing function for interinstitutional exchange of SOPs.

    NEA/CSNI Standard Problem 3 consists of the modelling of an experiment on the IETI-1 rig, in which there is initially flow upwards through a feeder, heated section and riser. The inlet and outlet are then closed and a breach opened at the bottom so that the flow reverses and the rig depressurises. Calculations of this problem by many countries using several computer codes have been reported and show a wide spread of results. The purpose of the study reported here was the following. First, to show the sensitivity of the calculation of Standard Problem 3. Second, to perform an ab initio best estimate calculation using the RELAP-UK Mark IV code with the standard recommended options, and third, to use the results of the sensitivity study to show where tuning of the RELAP-UK Mark IV recommended model options was required. This study has shown that the calculation of Standard Problem 3 is sensitive to model assumptions and that the use of the loss-of-coolant accident code RELAP-UK Mk IV with the standard recommended model options predicts the experimental results very well over most of the transient.

    Full Text Available Abstract Background Drowning is a constant global problem which claims approximately half a million victims worldwide each year, whereas the number of near-drowning victims is considerably higher. Public health strategies to reduce the burden of death are still limited. While research activities in the subject drowning grow constantly, yet there is no scientometric evaluation of the existing literature at the present time. Methods The current study uses classical bibliometric tools and visualizing techniques such as density equalizing mapping to analyse and evaluate the scientific research in the field of drowning. The interpretation of the achieved results is also implemented in the context of the data collection of the WHO. Results All studies related to drowning and listed in the ISI-Web of Science database since 1900 were identified using the search term "drowning". Implementing bibliometric methods, a constant increase in quantitative markers such as number of publications per state, publication language or collaborations as well as qualitative markers such as citations were observed for research in the field of drowning. The combination with density equalizing mapping exposed different global patterns for research productivity and the total number of drowning deaths and drowning rates respectively. Chart techniques were used to illustrate bi- and multilateral research cooperation. Conclusions The present study provides the first scientometric approach that visualizes research activity on the subject of drowning. It can be assumed that the scientific approach to this topic will achieve even greater dimensions because of its continuing actuality.

    Inverse modeling studies employing data collected from the classic Henry seawater intrusion problem give insight into several important aspects of inverse modeling of seawater intrusion problems and effective measurement strategies for estimation of parameters for seawater intrusion. Despite the simplicity of the Henry problem, it embodies the behavior of a typical seawater intrusion situation in a single aquifer. Data collected from the numerical problem solution are employed without added noise in order to focus on the aspects of inverse modeling strategies dictated by the physics of variable-density flow and solute transport during seawater intrusion. Covariances of model parameters that can be estimated are strongly dependent on the physics. The insights gained from this type of analysis may be directly applied to field problems in the presence of data errors, using standard inverse modeling approaches to deal with uncertainty in data. Covariance analysis of the Henry problem indicates that in order to generally reduce variance of parameter estimates, the ideal places to measure pressure are as far away from the coast as possible, at any depth, and the ideal places to measure concentration are near the bottom of the aquifer between the center of the transition zone and its inland fringe. These observations are located in and near high-sensitivity regions of system parameters, which may be identified in a sensitivity analysis with respect to several parameters. However, both the form of error distribution in the observations and the observation weights impact the spatial sensitivity distributions, and different choices for error distributions or weights can result in significantly different regions of high sensitivity. Thus, in order to design effective sampling networks, the error form and weights must be carefully considered. For the Henry problem, permeability and freshwater inflow can be estimated with low estimation variance from only pressure or only

    The International Standard Problem (ISP) No. 45 is part of the overall ISP program of the OECD/NEA and is dedicated to the behavior of heat-up and delayed reflood of fuel elements in nuclear reactors. ISP-45 is related to the out-of-pile bundle quench experiment QUENCH-06, performed at Forschungszentrum Karlsruhe (FZK), Germany, on December 13, 2000. Special attention was paid to hydrogen production. To assess the ability of severe accident codes to simulate processes during core heat-up and reflood at temperatures above 2000 K, the behavior of the bundle during the whole experiment should be caculated on the basis of experimental initial and boundary conditions, but without knowing further experimental details (blind phase). In the blind phase 21 participants from 15 nations contributed with 8 different code systems (ATHLET-CD, ICARE/CATHARE, IMPACT/SAMPSON, GENFLO, MAAP, MELCOR, SCDAPSIM, SCDAP-3D). After the end of the blind phase all measured data were made available and the participants were invited to deliver a second calculation, where this knowledge could be used (open phase). In this report, results of the blind calculations are presented, analyzed, and compared to experimental data. Additionally, post-test calculations using the in-house version SCDAP/RELAP5 mod3.2.irs are used for comparison. During heat-up most results do not deviate significantly from one another, except as a consequence of some obvious user errors, so that a definition of a mainstream is justified. During quenching the lack of adequate hydraulic modeling becomes obvious: some participants could not match the observed cool-down rates, others had to use a very fine mesh to compensate code deficiencies. To overcome this insufficiency some newly developed reflood models were used in MAAP and MELCOR. In QUENCH-06, the sufficiently thick oxide layers protected the cladding from melting and failure below 2200 K, so that no massive hydrogen release during reflood was found. This behavior

    The present report summarizes the results of the International Standard Problem Exercise ISP-29, based on the HDR Hydrogen Distribution Experiment E11.2. Post-test analyses are compared to experimentally measured parameters, well-known to the analysis. This report has been prepared by the Institute for Reactor Dynamics and Reactor Safety of the Technical University Munich under contract with the Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) which received funding for this activity from the German Ministry for Research and Technology (BMFT) under the research contract RS 792. The HDR experiment E11.2 has been performed by the Kernforschungszentrum Karlsruhe (KfK) in the frame of the project 'Projekt HDR-Sicherheitsprogramm' sponsored by the BMFT. Ten institutions from eight countries participated in the post-test analysis exercise which was focussing on the long-lasting gas distribution processes expected inside a PWR containment under severe accident conditions. The gas release experiment was coupled to a long-lasting steam release into the containment typical for an unmitigated small break loss-of-coolant accident. In lieu of pure hydrogen a gas mixture consisting of 15% hydrogen and 85% helium has been applied in order to avoid reaching flammability during the experiment. Of central importance are common overlay plots comparing calculated transients with measurements of the global pressure, the local temperature-, steam- and gas concentration distributions throughout the entire HDR containment. The comparisons indicate relatively large margins between most calculations and the experiment. Having in mind that this exercise was specified as an 'open post-test' analysis of well-known measured data the reasons for discrepancies between measurements and simulations were extensively discussed during a final workshop. It was concluded that analytical shortcomings as well as some uncertainties of experimental boundary conditions may be responsible for deviations

  9. International standard problem (ISP) No. 43 Rapid boron-dilution transient tests for code verification. Comparison report

    2001-03-01

    International Standard Problem No. 43 (ISP 43) addresses the nuclear industries present capabilities of simulating fluid dynamics aspects of a subset of rapid boron dilution transients. Specifically, the exercise focuses on the sequence involving the transport of a boron-dilute slug through the actuation of a pump. The slug is formed on the primary side of the steam generator as a consequence of in interfacing system leak from the secondary un-borated coolant. Experimental data was collected using the University of Maryland 2 x 4 Thermalhydraulic Loop (UM 2 x 4 Loop) and the Boron-mixing Visualization Facility. Two blind test series were proposed during the first workshop (October 1998) and refined using participant input. The first series, test series A, deals with the injection of a front, i.e., a single interface between borated and dilute fluids. The second blind series, test series B, is the more realistic injection of a slug, i.e., a dilute fluid volume preceded and followed by the borated coolant of the primary system. Data are collected in the UM 2 x 4 Loop and refined details are obtained from the Visualization Facility, which represents a replica of the Loop.s vessel downcomer. In the Loop experimental program, the dilute volume is simulated by cold water and the borated primary coolant is simulated by hot water. The Visualization Facility uses dye to mark the diluted front or slug. The measured boundary conditions for both test series include the initial temperature of the primary system, the front/slug injection flowrate and temperature, and the pressure drop across the core. Temperature data is collected at 185 thermocouple positions in the downcomer and 38 positions in the lower plenum. The advancement of the front/slug through the system is monitored at discrete horizontal levels that contain the thermocouples. The performance of codes is measured relative to a set of figures of merit. During the first workshop, the principal figure of merit was

    Fish bile metallothioneins (MT) have been recently reported as biomarkers for environmental metal contamination; however, no studies regarding standardizations for their purification are available. Therefore, different procedures (varying centrifugation times and heat-treatment temperatures) and reducing agents (DTT, β-mercaptoethanol and TCEP) were applied to purify MT isolated from fish (Oreochromis niloticus) bile and liver. Liver was also analyzed, since these two organs are intrinsically connected and show the same trend regarding MT expression. Spectrophotometrical analyses were used to quantify the resulting MT samples, and SDS-PAGE gels were used to qualitatively assess the different procedure results. Each procedure was then statistically evaluated and a multivariate statistical analysis was then applied. A response surface methodology was also applied for bile samples, in order to further evaluate the responses for this matrix. Heat treatment effectively removes most undesired proteins from the samples, however results indicate that temperatures above 70 °C are not efficient since they also remove MTs from both bile and liver samples. Our results also indicate that the centrifugation times described in the literature can be decreased in order to analyze more samples in the same timeframe, of importance in environmental monitoring contexts where samples are usually numerous. In an environmental context, biliary MT was lower than liver MT, as expected, since liver accumulates MT with slower detoxification rates than bile, which is released from the gallbladder during feeding, and then diluted by water. Therefore, bile MT seems to be more adequate in environmental monitoring scopes regarding recent exposure to xenobiotics that may affect the proteomic and metalloproteomic expression of this biological matrix.

    1997-01-01

    We report the development of a methodology using isochronal and isothermal anneals for the characterization of MOS (Metal - Oxide - Semiconductor) Transistors irradiated electronic components. We study the recovery kinetics of the post-irradiation effects and the modeling of the recovery temperature activated phenomena. This allows us to understand the basic physical mechanisms that have led to the definition of standard test procedures. The fields of application are numerous (space, military, accelerators for high energy physics, civilian nuclear and harsh environment robotics). We begin by outlining the context of our study and by presenting the actual standard test procedures (TM1019.4 and BS22900) used for the qualification of integrated circuits. We then review the different theories of the temperature activated phenomena. The link between the foundations of the normalized procedures and the thermally activated phenomena is clarified. From this analysis, we propose a new approach, mainly based on the use of isochronal anneals. During this work, we have developed two tools with this aim: - the first tool is software, it is a numerical simulation program for thermally activated phenomena. - The second is composed of a specific automated annealing bench (in particular isochronal), that we have designed. The applications and results are then presented in four parts: - the first presents simulation results computed using our calculation code, - the second concerns experimental results obtained with thin oxides from different rad-hard technologies and their application to study gate oxides of transistors, - the third develops results on non-hardened technological thick oxides and their consequences on the lateral leakage currents due to parasitic MOS structures in the 'commercial' components, - the fourth concerns the post-irradiation evolution of interface states during isochronal anneals. We conclude with a number of recommendations concerning the post

    We aimed to compare the performance of the ZeroGravity (ZG) system (radiation protection system composed by a suspended lead suit) against the use of standard protection (lead apron (LA), thyroid shield, lead eyeglasses, table skirts, and ceiling suspended shield) in neuroangiography procedures. Radiation exposure data were prospectively collected in consecutive neuroendovascular procedures between December 2014 and February 2015. Operator No 1 was assigned to the use of an LA (plus lead glasses, thyroid shield, and a 1 mm hanging shield at the groin) while operator No 2 utilized the ZG system. Dosimeters were used to measure peak skin dose for the head, thyroid, and left foot. The two operators performed a total of 122 procedures during the study period. The ZG operator was more commonly the primary operator compared with the LA operator (85% vs 71%; p=0.04). The mean anterior-posterior (AP), lateral, and cumulative dose area product (DAP) radiation exposure as well as the mean fluoroscopy time were not statistically different between the operators' cases. The peak skin dose to the head of the operator with LA was 2.1 times higher (3380 vs 1600 μSv), while the thyroid was 13.9 (4460 vs 320 μSv), the mediastinum infinitely (520 vs 0 μSv), and the foot 3.3 times higher (4870 vs 1470 μSv) compared with the ZG operator, leading to an overall accumulated dose 4 times higher. The ratio of cumulative operator received dose/total cumulative DAP was 2.5 higher on the LA operator. The ZG radiation protection system leads to substantially lower radiation exposure to the operator in neurointerventional procedures. However, substantial exposure may still occur at the level of the lens and thyroid to justify additional protection. Published by the BMJ Publishing Group Limited.

    Sepsis is a common, costly and morbid cause of critical illness in trauma and surgical patients. Ongoing advances in sepsis resuscitation and critical care support strategies have led to improved in-hospital mortality. However, these patients now survive to enter state of chronic critical illness (CCI), persistent low-grade organ dysfunction and poor long-term outcomes driven by the persistent inflammation, immunosuppression and catabolism syndrome (PICS). The Sepsis and Critical Illness Research Center (SCIRC) was created to provide a platform by which the prevalence and pathogenesis of CCI and PICS may be understood at a mechanistic level across multiple medical disciplines, leading to the development of novel management strategies and targeted therapies. Here, we describe the design, study cohort and standard operating procedures used in the prospective study of human sepsis at a level 1 trauma centre and tertiary care hospital providing care for over 2600 critically ill patients annually. These procedures include implementation of an automated sepsis surveillance initiative, augmentation of clinical decisions with a computerised sepsis protocol, strategies for direct exportation of quality-filtered data from the electronic medical record to a research database and robust long-term follow-up. This study has been registered at ClinicalTrials.gov, approved by the University of Florida Institutional Review Board and is actively enrolling subjects.

    The use of the radiotherapy implies the necessity of rigorous quality standards in its different components, aiming to provide the best possible treatment and avoid potential patient's risks, that could even cause his/her death. Projects of technical cooperation have been developed in Cuba support by the International Atomic Energy Agency addresses to the implementation of Programs of Quality Assurance in radiotherapy services. The establishment of the National Quality Audit Program (PNAC) is a superior stage. The National Control Center for Medical Devices as the national regulator entity for the control and supervision of medical devices in the National Health System is the responsible for the making and execution of the PNAC. The audit modality selected was the inspection visit in situ due to its intrinsic advantages, our geographical extension and the number of radiotherapy services. This paper presents the methodology for the execution of the PNAC, in form of a Normalized Procedure of Operation that defines the objectives, scope, terms and definitions, responsibilities, composition and selection of the auditor team, security's conditions, materials and equipment, steps of the audit execution, results calculation and interpretation, records, etc. (author)

    Hypnosis is regarded as an effective treatment for psychological and physical ailments. However, its efficacy as a strategy for managing chronic pain has not been assessed through meta-analytical methods. The objective of the current study was to conduct a meta-analysis to assess the efficacy of hypnosis for managing chronic pain. When compared with standard care, hypnosis provided moderate treatment benefit. Hypnosis also showed a moderate superior effect as compared to other psychological interventions for a nonheadache group. The results suggest that hypnosis is efficacious for managing chronic pain. Given that large heterogeneity among the included studies was identified, the nature of hypnosis treatment is further discussed.

    Throughout the nineteenth century, the sciences in the United States went through many professional and disciplinary shifts. While the impact of these changes on university education has been well established, their consequences at the level of high school education have been often overlooked. In mathematics, debates at the level of university officials found clear outlets in the reform movement concerning secondary school offerings and college entrance requirements. This article therefore focuses on these debates and also the attempts to achieve compromises through standardized curricula in the recommendations of the Committee of Ten. In discussing the interplay between university and secondary education, it exposes a feature of the history of science education that has been neglected.

    patients who had undergone an RBT hysterectomy compared to a standard total LSC hysterectomy for benign indications.13 A recent cost analysis suggested that patients experienced less pain and required less pain medication use after RBT procedures compared to LSC for endometrial cancer.14 Based on these reports, we sought to analyze postoperative pain and the use of pain medication in patients undergoing RBT compared to standard transperitoneal LSC procedures for newly diagnosed endometrial cancer during a concurrent time period. Of note, current RBT surgery is not truly robotic in that it is not autonomous. A more appropriate term is “computer-assisted surgery,” but to satisfy current convention, we refer to it as “robotic surgery” in this manuscript.

 Critics to the standard model of analogical problems solving and proposals for an alternative one

    Full Text Available The authors made an extension of Hofstadter‘s criticisms against the standard approach in analogical thinking represented by the structure-mapping theory of Gentner and the multiconstraint theory of Holyoak and Thagard. Based on this extension, they proposed a non-serial model of analogical problem solving. Against the standard approach, the model postulates that: (a people detect and evaluate differences between mapped elements before the subprocess of inference generation and consider them in order to control it, and (b properties of an element that explain why the element could fill a certain role in the base problem resolution (PERs play a crucial role in these detection and evaluation operations, and also in post-inferences subprocesses. An experiment showed that: (a people detect and evaluate the relevance of differences between mapped elements before inference generation, (b that they inhibit the generation of literal inferences when they face relevant differences, and (c that they stop the subprocess when they recognize insuperable ones. The results also showed that base PERs are reactivated at different moments of analogical transfer. The data obtained are incompatible with the standard theories of analogical thinking, which treat inference generation as a syntactic mechanism and exclude contextual semantic analysis from the study of analogy.

    An understanding of the effects on human and ecological health brought by major coastal storms or flooding events is typically limited because of a lack of regionally consistent baseline and trends data in locations proximal to potential contaminant sources and mitigation activities, sensitive ecosystems, and recreational facilities where exposures are probable. In an attempt to close this gap, the U.S. Geological Survey (USGS) has implemented the Sediment-bound Contaminant Resiliency and Response (SCoRR) strategy pilot study to collect regional sediment-quality data prior to and in response to future coastal storms. The standard operating procedure (SOP) detailed in this document serves as the sample-collection protocol for the SCoRR strategy by providing step-by-step instructions for site preparation, sample collection and processing, and shipping of soil and surficial sediment (for example, bed sediment, marsh sediment, or beach material). The objectives of the SCoRR strategy pilot study are (1) to create a baseline of soil-, sand-, marsh sediment-, and bed-sediment-quality data from sites located in the coastal counties from Maine to Virginia based on their potential risk of being contaminated in the event of a major coastal storm or flooding (defined as Resiliency mode); and (2) respond to major coastal storms and flooding by reoccupying select baseline sites and sampling within days of the event (defined as Response mode). For both modes, samples are collected in a consistent manner to minimize bias and maximize quality control by ensuring that all sampling personnel across the region collect, document, and process soil and sediment samples following the procedures outlined in this SOP. Samples are analyzed using four USGS-developed screening methods—inorganic geochemistry, organic geochemistry, pathogens, and biological assays—which are also outlined in this SOP. Because the SCoRR strategy employs a multi-metric approach for sample analyses, this

    Facing the new demands of the optical fiber communications market, almost all the performance and reliability of optical network system are dependent on the qualification of the fiber optics components. So, how to comply with the system requirements, the Telcordia / Bellcore reliability and high-power testing has become the key issue for the fiber optics components manufacturers. The qualification of Telcordia / Bellcore reliability or high-power testing is a crucial issue for the manufacturers. It is relating to who is the outstanding one in the intense competition market. These testing also need maintenances and optimizations. Now, work on the reliability and high-power testing have become the new demands in the market. The way is needed to get the 'Triple-Win' goal expected by the component-makers, the reliability-testers and the system-users. To those who are meeting practical problems for the testing, there are following seven topics that deal with how to shoot the common mistakes to perform qualify reliability and high-power testing: ¸ Qualification maintenance requirements for the reliability testing ¸ Lots control for preparing the reliability testing ¸ Sampling select per the reliability testing ¸ Interim measurements during the reliability testing ¸ Basic referencing factors relating to the high-power testing ¸ Necessity of re-qualification testing for the changing of producing ¸ Understanding the similarity for product family by the definitions

    The determination of the precise position of permanent first and second modern human molars, following standard tooth identification criteria, is often difficult because of their morphological similarities. Here, we proposed to evaluate the suitability of two-dimensional crown contour shape analysis in achieving this objective. The method was tested separately on 180 first and second maxillary molars (UM) and 180 first and second mandibular molars (LM) securely identified (in anatomical position in their sockets). Generalized Procrustes superimposition is used to normalize the outlines prior to applying elliptic Fourier analyses ("EFAproc" method). Reliability and effectiveness of this morphometric procedure was evaluated by comparing the results obtained for the same dataset with four other morphometric methods of contour analysis. Cross-validated ("leave one individual out") percentages of misclassification yielded by linear discriminant analyses were used for determining the anatomic position of modern human molars. The percentages of misclassifications obtained from every method of contour analysis were low (1.67% to 3.33% for the UM, 5.56% to 6.67% for the LM) indicating the high suitability of crown contour analyses in correctly identifying molars. A reliable protocol, based on predictive linear discriminant analyses, was then proposed for identification of isolated molars. In addition, our results confirmed that the EFAproc method is suitable for normalizing outlines prior to undertaking elliptic Fourier analyses, especially in the case of nearly circular outlines: it obtained better classification than the classic method of normalization of Fourier descriptors for UM and provided also some advantages over the three landmarks-based methods tested here.

    The objective of the present study was to analyze the experience of the coroners and pathologists in the Great Britain based on the results of the coroner's autopsies and recommendations of the experts involved in the activities carried out in the framework of the National Confidential Enquiry into Patient Outcome and Death program (NCEPOD). The recommendations are designed to reform the country's medical examiner system, improve the equipment of the mortuary facilities, and optimize funding for the autopsy studies. The authors consider in the chronological order the following issues of the coroners and pathologists' activities: organization of their work and its procedural aspects, ordering coroner's autopsies, preparation for their performance, analysis of the relevant documentation (autopsy reports) and medical case histories (discharge summaries). Also discussed are the recommendations of the NCEPOD experts for the improvement of the said studies with the detailed analysis of the causes underlying the aforementioned problems and concise comments of the authors.

    The National Institute of Care Excellence (NICE) 2007 guidance CG54, on urinary tract infection (UTI) in children, states that clinicians should use urgent microscopy and culture as the preferred method for diagnosing UTI in the hospital setting for severe illness in children under 3 years old and from the GP setting in children under 3 years old with intermediate risk of severe illness. NICE also recommends that all 'infants and children with atypical UTI (including non-Escherichia coli infections) should have renal imaging after a first infection'. We surveyed all microbiology laboratories in England with Clinical Pathology Accreditation to determine standard operating procedures (SOPs) for urgent microscopy, culture and reporting of children's urine and to ascertain whether the SOPs facilitate compliance with NICE guidance. We undertook a computer search in six microbiology laboratories in south-west England to determine urine submissions and urine reports in children under 3 years. Seventy-three per cent of laboratories (110/150) participated. Enterobacteriaceae that were not E. coli were reported only as coliforms (rather than non-E. coli coliforms) by 61% (67/110) of laboratories. Eighty-eight per cent of laboratories (97/110) provided urgent microscopy for hospital and 54% for general practice (GP) paediatric urines; 61% of laboratories (confidence interval 52-70%) cultured 1 μl volume of urine, which equates to one colony if the bacterial load is 106 c.f.u. l(-1). Only 22% (24/110) of laboratories reported non-E. coli coliforms and provided urgent microscopy for both hospital and GP childhood urines; only three laboratories also cultured a 5 μl volume of urine. Only one of six laboratories in our submission audit had a significant increase in urine submissions and urines reported from children less than 3 years old between the predicted pre-2007 level in the absence of guidance and the 2008 level following publication of the NICE guidance.

    The modern counting instrumentation has largely obviated the need for separation processes in the radiochemical analysis but problems in low-level radioactivity measurement, environmental-type analyses, and special situations caused in the last years a renaissance of the need for separation techniques. Most of the radiochemical procedures, based on the classic works of the Manhattan Project chemists of the 1940's, were published in the National Nuclear Energy Series (NNES). Improvements such as new solvent extraction and ion exchange separations have been added to these methods throughout the years. Recently the Los Alamos Group have reissued their collected Radiochemical Procedures containing a short summary and review of basic inorganic chemistry - 'Chemistry of the Elements on the Basis of Electronic Configuration'.

    This paper presents comparisons between two computer code predictions and experimental measurements of the structural response of a pipe line/check valve system subjected to loading from a loss of feedwater transient. The piping system that was modeled and instrumented for measurement was the focus of German Standard Problem 4a; part of the Heissdampfreaktor Safety Program being conducted in the Federal Republic of Germany. The availability of their experimental data offered EG and G a unique opportunity to evaluate two structural codes' predictions, to compare them with each other, and to compare their predictions with the actual measured values of acceleration and displacement. A thermal-hydrualic code, SOLA-LOOP, computed the hydraulic behavior of the system. The hydraulic forcing functions were calculated and placed into the structural codes, NUPIPE-II and SAP IV. It was concluded that both computer programs provided comparable, realistic predictions of the piping system dynamic response to a blowdown load.

    The ToyBox-intervention is a kindergarten-based, family-involved intervention targeting multiple lifestyle behaviours in preschool children, their teachers and their families. This intervention was conducted in six European countries, namely Belgium, Bulgaria, Germany, Greece, Poland and Spain. The aim of this paper is to provide a descriptive overview of the harmonization and standardization procedures of the baseline and follow-up evaluation of the study (and substudies). Steps related to the study's operational, standardization and harmonization procedures as well as the impact and outcome evaluation assessment tools used are presented. Experiences from the project highlight the importance of safeguarding the measurement process to minimize data heterogeneity derived from potential measurement error and country-by-country differences. In addition, it was made clear that continuing quality control and support is an important component of such studies. For this reason, well-supported communication channels, such as regular email updates and teleconferences, and regular internal and external meetings to ensure smooth and accurate implementation were in place during the study. The ToyBox-intervention and its harmonized and standardized procedures can serve as a successful case study for future studies evaluating the efficacy of similar interventions. © 2014 World Obesity.

However, only combinations where symptoms are mutually influential hold potential for identifying patient subgroups at greater risk, and in some contexts, interventions with "cross-over" (multisymptom effects. Improved methods to detect and interpret interactions among symptoms, signs, or biomarkers are needed to reveal these influential pairs and clusters. I recently created sequential residual centering (SRC to reduce multicollinearity in moderated regression, which enhances sensitivity to detect these interactions. Methods: I applied SRC to moderated regressions of single-item symptoms that interact to predict outcomes from 268 palliative radiation outpatients. I investigated: 1 the hypothesis that the interaction, pain × fatigue/weakness × sleep problems, predicts depressive affect only when fever presents, and 2 an exploratory analysis, when fever is absent, that the interaction, pain × fatigue/weakness × sleep problems × depressive affect, predicts mobility problems. In the fever context, three-way interactions (and derivative terms of the four symptoms (pain, fatigue/weakness, fever, sleep problems are tested individually and simultaneously; in the non-fever context, a single four-way interaction (and derivative terms is tested. Results: Fever interacts separately with fatigue/weakness and sleep problems; these comoderators each magnify the pain–depressive affect relationship along the upper or full range of pain values. In non-fever contexts, fatigue/weakness, sleep problems, and depressive affect comagnify the relationship between pain and mobility problems. Conclusion: Different mechanisms

    The development of policies and procedures is an integral part of the occupational health nurse's role. Policies and procedures serve as the foundation for the occupational health service and are based on its vision, mission, culture, and values. The design and layout selected for the policies and procedures should be simple, consistent, and easy to use. The same format should be used for all existing and new policies and procedures. Policies and procedures should be reviewed periodically based on a specified time frame (i.e., annually). However, some policies may require a more frequent review if they involve rapidly changing external standards, ethical issues, or emerging exposures.

    2016-12-01

    During the last decade, the stringent pressures from environmental and social requirements have spurred an interest in designing a reverse logistics (RL) network. The success of a logistics system may depend on the decisions of the facilities locations and vehicle routings. The location-routing problem (LRP) simultaneously locates the facilities and designs the travel routes for vehicles among established facilities and existing demand points. In this paper, the location-routing problem with time window (LRPTW) and homogeneous fleet type and designing a multi-echelon, and capacitated reverse logistics network, are considered which may arise in many real-life situations in logistics management. Our proposed RL network consists of hybrid collection/inspection centers, recovery centers and disposal centers. Here, we present a new bi-objective mathematical programming (BOMP) for LRPTW in reverse logistic. Since this type of problem is NP-hard, the non-dominated sorting genetic algorithm II (NSGA-II) is proposed to obtain the Pareto frontier for the given problem. Several numerical examples are presented to illustrate the effectiveness of the proposed model and algorithm. Also, the present work is an effort to effectively implement the ɛ-constraint method in GAMS software for producing the Pareto-optimal solutions in a BOMP. The results of the proposed algorithm have been compared with the ɛ-constraint method. The computational results show that the ɛ-constraint method is able to solve small-size instances to optimality within reasonable computing times, and for medium-to-large-sized problems, the proposed NSGA-II works better than the ɛ-constraint.

    The Irish National Consent Policy (NCP)¹ proposes that the legal requirement for consent extends to all forms of interventions, investigations and treatment, carried out on or behalf of the Health Service Executive (HSE). This study employs a quantitative descriptive approach to investigate the practices for obtaining consent for an identified group of routine neonatal procedures in neonatal facilities throughout Ireland. The BAPM (British Association of Perinatal Medicine)² guidelines were identified as ‘gold standard’ for the purposes of this study. The results indicated a lack of consistency between participating units pertaining to the modes of consent utilised and notable variances from ‘gold standard’ guidelines. Unanimity was evident for 3 procedures only (administering BCG, 6-in-1, and donor breast milk to infant). Significant findings related to EEG with video recordings, MRI\\/CT and gastro intestinal imaging, screening of an infant with suspected substance abuse or retinopathy of prematurity screening (ROP), administration of Vitamin K, and the carrying out of a lumbar puncture.

    In this paper we present a model for the value of a firm based on observable variables and parameters: the annual turnover, the expenses, interest rates. This value is the solution of a parabolic partial differential equation. We show how the value of the company depends on its legal status such as its liability (that is, whether it is a Limited Company or a sole trader/partnership). We give examples of how the operating procedures can be optimized (for example, whether the firm should close down, relocate etc.). Finally, we show how the model can be used to value the debt issued by the firm.

    International Nuclear Information System (INIS)

    2005-01-01

    At the CSNI meeting in June 2002, the proposal for an International Standard Problem on containment integrity (ISP 48) based on the NRC/NUPEC/Sandia test was approved. Objectives were to extend the understanding of capacities of actual containment structures based on results of the recent PCCV Model test and other previous research. The ISP was sponsored by the USNRC, and results had been made available thanks to NUPEC and to the USNRC. Sandia National Laboratory was contracted to manage the technical aspects of the ISP. At the end of the ISP48, a workshop was organized in Lyon, France on April 6-7, 2005 hosted by Electricite de France. Its overall objective was to present results obtained by participants in the ISP 48 and to assess the current practices and the state of the art with respect to the calculation of concrete structures under severe accident conditions. Experience from other areas in civil engineering related to the modelling of complex structures was greatly beneficial to all. Information obtained as a result of this assessment were utilized to develop a consensus on these calculations and identify issues or 'gaps' in the present knowledge for the primary purpose of formulating and prioritizing research needs on this topic.

    Filamentous fungi and yeasts are increasingly isolated from respiratory secretions of patients with cystic fibrosis (CF), and persistent fungal colonization of the airways of such patients is thought to exacerbate lung damage. While many independent studies have identified Aspergillus fumigatus complex as the principal colonizing fungus in CF, increased awareness of the role of fungi in CF pathology coupled with improved mycological culture and identification methods have resulted in a number of other fungi being isolated and reported from CF sputum samples, including A. terreus, members of the Pseudallescheria boydii/Scedosporium apiospermum complex, Exophiala dermatitidis, Paecilomyces and Penicillium species. However, the range of fungal pathogens isolated and the relative prevalence of individual species vary widely between reports from different geographical CF centres, and as yet no standardized method for the mycological examination of CF sputum samples has been adopted. Here, we examine the potential contribution of the mycological methods employed to examine CF respiratory secretions relative to the variability in the fungal biota reported. The role of direct microscopic examination of respiratory samples and the impact of the culture conditions used on the detection of specific fungal pathogens are addressed, and the potential significance of isolation of yeast species from CF patient airways is discussed.

    A small number of young mentally ill persons consumes a disproportionate amount of psychiatric service resources. These persons are characterised by emotional instability, aggressive or delinquent behaviour, substance misuse and personality disorders. They are sometimes referred to as young adult chronic patients (YACP). To date there has been no investigation as to what impact this pattern of problem behaviour has on vocational rehabilitation. The aim of this study was to find out whether belonging to the YACP group, as determined by an operational definition, reduces the outcome of vocational rehabilitation. A chart review was done of the files of all 174 participants of a 15-month vocational training course held between 1.1.1993 and 2.5.1998 in the vocational training centre at Cologne. A 15-item score was used to assess YACP status. 30 % were classified as high scorers, i. e. YACP. 59 % of the high scorers vs. 22 % of the low scorers terminated training prematurely. Of the high scorers who completed training, only 47 (vs. 74 % of low scorers) were judged to be able to work at the end of training. At the very beginning of the vocational training persons in need of a highly individualised format can be discerned by a few, easy to assess items. Concepts of vocational training should be developed to better suit the needs of young mentally ill persons with personality disorders and substance abuse.

    Drowning is a constant global problem which claims approximately half a million victims worldwide each year, whereas the number of near-drowning victims is considerably higher. Public health strategies to reduce the burden of death are still limited. While research activities in the subject drowning grow constantly, yet there is no scientometric evaluation of the existing literature at the present time. The current study uses classical bibliometric tools and visualizing techniques such as density equalizing mapping to analyse and evaluate the scientific research in the field of drowning. The interpretation of the achieved results is also implemented in the context of the data collection of the WHO. All studies related to drowning and listed in the ISI-Web of Science database since 1900 were identified using the search term "drowning". Implementing bibliometric methods, a constant increase in quantitative markers such as number of publications per state, publication language or collaborations as well as qualitative markers such as citations were observed for research in the field of drowning. The combination with density equalizing mapping exposed different global patterns for research productivity and the total number of drowning deaths and drowning rates respectively. Chart techniques were used to illustrate bi- and multilateral research cooperation. The present study provides the first scientometric approach that visualizes research activity on the subject of drowning. It can be assumed that the scientific approach to this topic will achieve even greater dimensions because of its continuing actuality.

    To determine whether systematic use of a validated social-emotional screening instrument in a primary care setting is feasible and improves detection of social-emotional problems among youth in foster care. Before-and-after study design, following a practice intervention to screen all youth in foster care for psychosocial problems using the Strengths and Difficulties Questionnaire (SDQ), a validated instrument with 5 subdomains. After implementation of systematic screening, youth aged 11 to 17 years and their foster parents completed the SDQ at routine health maintenance visits. We assessed feasibility of screening by measuring the completion rates of SDQ by youth and foster parents. We compared the detection of psychosocial problems during a 2-year period before systematic screening to the detection after implementation of systematic screening with the SDQ. We used chart reviews to assess detection at baseline and after implementing systematic screening. Altogether, 92% of 212 youth with routine visits that occurred after initiation of screening had a completed SDQ in the medical record, demonstrating high feasibility of systematic screening. Detection of a potential mental health problem was higher in the screening period than baseline period for the entire population (54% vs 27%, P problem domains on the SDQ. Systematic screening for potential social-emotional problems among youth in foster care was feasible within a primary care setting and doubled the detection rate of potential psychosocial problems.

    Objective: To assess the quality and patient satisfaction in Endoscopy Unit of Shifa International Hospital. Study Design: Cross-sectional survey. Place and Duration of Study: Division of Gastroenterology, Shifa International Hospital, Islamabad, Pakistan, from July 2011 to January 2012. Methodology: Quality and patient satisfaction after the endoscopic procedure was assessed using a modified GHAA-9 questionnaire. Data was analyzed using SPSS version 16. Results: A total of 1028 patients were included with a mean age of 45 A+- 14.21 years. Out of all the procedures, 670 (65.17%) were gastroscopies, 181 (17.60%) were flexible sigmoidoscopies and 177 (17.21%) were colonoscopies. The maximum unsatisfactory responses were on the waiting time before the procedure (13.13 %), followed by unsatisfactory explanation of the procedure and answers to questions (7.58%). Overall, unsatisfied impression was 4.86%. The problem rate was 6.22%. Conclusion: The quality of procedures and level of satisfaction of patients undergoing a gastroscopy or colonoscopy was generally good. The factors that influence the satisfaction of these patients are related to communication between doctor and patient, doctor's manner and waiting time for the procedure. Feedback information in an endoscopy unit may be useful in improving standards, including the performance of endoscopists. (author)

    Individuals with a personal or family history of cancer, can opt for genetic counseling and DNA-testing. Approximately 25% of these individuals experience clinically relevant levels of psychosocial distress, depression and/or anxiety after counseling. These problems are frequently left undetected by genetic counselors. The aim of this study is to evaluate the efficacy of a cancer genetics-specific screening questionnaire for psychosocial problems, the 'Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire' together with the Distress Thermometer, in: (1) facilitating personalized counselor-counselee communication; (2) increasing counselors' awareness of their counselees' psychosocial problems; and (3) facilitating the management of psychosocial problems during and after genetic counseling. This multicenter, randomized controlled trial will include 264 individuals undergoing cancer genetic counseling in two family cancer clinics in the Netherlands. Participants will be randomized to either: (1) an intervention group that completes the PAHC questionnaire, the results of which are made available to the genetic counselor prior to the counseling session; or (2) a control group that completes the PAHC questionnaire, but without feedback being given to the genetic counselor. The genetic counseling sessions will be audiotaped for content analysis. Additionally, study participants will be asked to complete questionnaires at baseline, three weeks after the initial counseling session, and four months after a telephone follow-up counseling session. The genetic counselors will be asked to complete questionnaires at the start of and at completion of the study, as well as a checklist directly after each counseling session. The questionnaires/checklists of the study include items on communication during genetic counseling, counselor awareness of their clients' psychosocial problems, the (perceived) need for professional psychosocial support, cancer worries, general

    The tightness of control procedures in the legal protection provided by jurisdiction against directives issued by the Federal Government - a problem of competence distribution between the Federal Constitutional Court and the Federal Administrative Court? The article examines questions of recourse to the competent court, problems concerning the admissibility of legal proceedings before the Federal Admininstrative Court, the competence of the Laender in performing administrative acts on behalf of the Federation, the effectiveness of legal protection and the relationship between the Laender and the Federation in terms of responsibility for constitutional rights. The legal protection offered by administrative law, against a directive of the Federal Government is wholly ineffective, as there is no legal position a Land could bring into play to defened itself against a directive leading to unlawful action. Inequites which thus occur can however be met via a dispute between the Federation and the Laender as provided by the constitution, as the content of a directive becomes relevant in attempts to exert influence on the competence issue. Ultimately the rulings of the Basic Law on competence serve to protect the citizen and the community against excesses. In this connection the constitutional rights in their capacity as negative competence rulings disqualify executive acts. (orig./HSCH) [de

MÉTODOS: Foram descontaminadas, após a baciloscopia, 42 amostras de escarro de pacientes. Em seguida, procedeu-se ao cultivo em Lowenstein-Jensen e à reação em cadeia da polimerase com "primers" que amplificam um fragmento de 123 pares de base do genoma do Mycobacterium tuberculosis. RESULTADOS: Das 42 amostras de escarro, 10 apresentaram cultura positiva para M. tuberculosis. Dez foram positivas à baciloscopia e 16 mostraram-se positivas na reação em cadeia da polimerase. A sensibilidade e especificidade do teste em relação à cultura foi de 90% e 81%, respectivamente. CONCLUSÕES: A reação em cadeia da polimerase tem sensibilidade comparável à da cultura e pode ser realizada em apenas um dia, resultando em tratamento precoce e melhor controle da doença. A padronização e avaliação de técnicas de biologia molecular no diagnóstico da tuberculose no Brasil é imprescindível na discussão da implantação deste exame na rotina diagnóstica em centros de referência.INTRODUCTION: The recent increase in the number of tuberculosis cases has called the world's attention once again to a perennial health problem, especially prevalent in developing countries. The time elapsed between the diagnosis and the institution of therapy is an obstacle to tuberculosis control and there is an urgent need for the development of techniques for the disease's rapid diagnosis. To achieve this goal, molecular biology techniques have been exhaustively investigated. This work describes the use of a polymerase chain reaction for rapid diagnosis of tuberculosis in a developing country. The sensitivity and specificity of this technique is compared to standard techniques used in the microbiology laboratory. METHODS

    The accident of the Fukushima Daiichi Nuclear Station of Tokyo Electric Power Company associated with the Great East Japan Earthquake incurred severe situation, where lifeline was cut off due to the discharge of a large amount of radioactive substances. In particular, the supply of safe foods and drinking water in radiation-polluted areas is urgently required. The authors have been developing up to now Crystal Valley water purifier and CV-Rescue water purifier that can purify well-water unsuitable for drinking due to contamination with toxic substances and produce drinkable water with safety without anxiety. This paper introduces the processes, in which verification test was performed to confirm that the above purifiers can be used for the removal of radioactivity discharged from the Great East Japan Earthquake this time, the validity of these purifiers was clarified, and these purifiers have actually been used for supporting water supply. This paper especially points out that a problem exists in the various standards on radioactivity that were temporarily determined in face of emergency of radiation pollution due to the nuclear power station accident this time. In these standards, the temporary standard on radioactive iodine 131 in drinking water is too high compared with the standards of WHO and those of advanced countries like U.S.A. It also points out the problem that radioactive substances in drinking water have not been removed yet. (O.A.)

    The mitral valve prolapse syndrome may present with a variety of clinical manifestations and has proved to be a common cause of nonspecific cardiac symptoms in clinical practice. Primary and secondary forms must be distinguished. Myxomatous degeneration appears to be the common denominator of the primary form. The diagnostic standard of this form has not previously been defined because the detection of mitral leaflet tissue in the left atrium (prolapse) on physical examination or angiography is nonspecific. M mode echocardiography has greatly enhanced the recognition of this syndrome but has not proved to be the best diagnostic standard because of its limited view of mitral valve motion. The advent of two-dimensional echocardiography has provided the potential means for specific identification of the mitral leaflet motion in systole and can be considered the diagnostic standard for this syndrome. Primary myxomatous degeneration with leaflet prolapse is not localized to the mitral valve. Two-dimensional echocardiography has detected in preliminary studies tricuspid valve prolapse in up to 50% and aortic valve prolapse in about 20% of patients with idiopathic mitral valve prolapse
