EPR DOSIMETRY IN A MIXED NEUTRON AND GAMMA RADIATION FIELD
2004
Suitability of Electron Paramagnetic Resonance (EPR) spectroscopy for criticality dosimetry was evaluated for tooth enamel, mannose and alanine pellets during the 'international intercomparison of criticality dosimetry techniques' at the SILENE reactor held in Valduc in June 2002, France. These three materials were irradiated in neutron and gamma-ray fields of various relative intensities and spectral distributions in order to evaluate their neutron sensitivity. The neutron response was found to be around 10% for tooth enamel, 45% for mannose and between 40 and 90% for alanine pellets according their type. According to the IAEA recommendations on the early estimate of criticality accident a…
A magyar nyelvi standardhoz kapcsolódó nyelvi ideológiák a romániai Banságban
2009
A tanulmány a magyar nyelvi standarddal foglalkozik. A használt elméleti keret a nyelvi ideológiák kutatása, amelyet kiegészítettem a társalgáselemzés módszertanával. A nyelvi standard jellegzetesen ideológiai fogalom. A magyar nyelvészetben is nyelven kívüli jegyekkel definiálják a magyar nyelvi standard kifejezést. A magyar kultúra standard központú nyelvi kultúra, amelynek fő ismerve az, hogy a magyar nyelv alapjelentésben egyenlő standard változatával. Ez ellen a próbál tenni határtalanítás címen a szociólingvisták és a határon túli nyelvészek egy csoportja. A fő törekvésük a magyar standard fogalmat és ezzel együtt ’a magyar nyelv’ fogalmat befogadóbbá tenni. Az empirikus részben ismer…
Self-Efficacy and Study Burnout Among IT Students : Challenges and Potentials
2022
There is a risk of student dropout in the field of engineering, particularly in the domain of information technology. To find novel pedagogical and technological solutions to prevent student attrition, we must better understand student experiences regarding their learning and studying processes. This study was conducted within the introduction of a new engineering degree program at the University of Jyväskylä and focused on first-year students. The research questions are: How do IT students experience study burnout at the beginning of their studies? What kind of self-efficacy beliefs do IT students have at the beginning of their studies? How are the self-efficacy beliefs of IT students asso…
Normativitet: utfordring i psykoterapeutisk og pedagogisk arbeid. Den profesjonelle mellom tvang og frihet
2016
In this article we wish to discuss different normative dilemmas that teachers and psychotherapists meet in their work with the student and the patient. We argue that crucial for a good practice is not the actual choice between normativity and freedom, between generalized or authorized standards and individual dialogue. Rather it is the professional’s continuous reflection on the form and quality of the interactions with the pupil and the patient, and the preservation of the balance between personal ethos and professional responsibilities that best safeguard respect for the other's autonomy and self-determination. By illustrating psychotherapeutic malpractice and systematic mistreatment of c…
Multimodality imaging strategies for the assessment of aortic stenosis: Viewpoint of the heart valve clinic international database (HAVEC) group
2016
International audience; Aortic stenosis is the most frequent valvular heart disease. In aortic stenosis, therapeutic decision essentially depends on symptomatic status, stenosis severity, and status of left ventricular systolic function. Surgical aortic valve replacement or transcatheter aortic valve implantation is the sole effective therapy in symptomatic patients with severe aortic stenosis, whereas the management of asymptomatic patients remains controversial and is mainly based on individual risk stratification. Imaging is fundamental for the initial diagnostic work-up, follow-up, and selection of the optimal timing and type of intervention. The present review provides specific recomme…
Air pollution and airport apron workers: A neglected occupational setting in epidemiological research.
2020
Abstract Introduction Airport apron workers are occupationally exposed to jet exhaust and major concern is related to the exposure to ultrafine particles (UFP) from aircrafts. To date, little attention has been given to occupational exposures to aircraft-related UFP, although aircraft engines have high emissions of ultrafine particles, which are orders of magnitude higher than residential exposure. UFP could possibly contribute to the development of cancer, heart disease, mental illness, and respiratory symptoms. In addition to particulate matter, apron workers are exposed to other polluting substances associated with vehicles, aircraft exhaust or direct fuel emissions. Methods We performed…
Standardized Hemorrhagic Shock Induction Guided by Cerebral Oximetry and Extended Hemodynamic Monitoring in Pigs.
2019
Hemorrhagic shock ranks among the main reasons for severe injury-related death. The loss of circulatory volume and oxygen carriers can lead to an insufficient oxygen supply and irreversible organ failure. The brain exerts only limited compensation capacities and is particularly at high risk of severe hypoxic damage.This article demonstrates the reproducible induction of life-threatening hemorrhagic shock in a porcine model by means of calculated blood withdrawal. We titrate shock induction guided by near-infrared spectroscopy and extended hemodynamic monitoring to display systemic circulatory failure, as well as cerebral microcirculatory oxygen depletion. In comparison to similar models tha…
Defizite bei der Erfassung transplantationsrelevanter Daten in Deutschland
2011
Collection of data in transplantation medicine is required to define ethical standards, to assess indications and contra-indications and to determine rules for organ allocation. Similarly, assessment of quality of the transplantation process and practice of transplantation centres requires relevant data in transplantation medicine. Apart from data in quality reports, Eurotransplant and organ procurement, any form of data collection is lacking in Germany. In this article the problems caused by this shortcoming are described.
Calculation of NNTs in RCTs with time-to-event outcomes: A literature review
2008
Abstract Background The number needed to treat (NNT) is a well-known effect measure for reporting the results of clinical trials. In the case of time-to-event outcomes, the calculation of NNTs is more difficult than in the case of binary data. The frequency of using NNTs to report results of randomised controlled trials (RCT) investigating time-to-event outcomes and the adequacy of the applied calculation methods are unknown. Methods We searched in PubMed for RCTs with parallel group design and individual randomisation, published in four frequently cited journals between 2003 and 2005. We evaluated the type of outcome, the frequency of reporting NNTs with corresponding confidence intervals,…
Evaluation of the quality of publications on randomized clinical trials using the Consolidated Standards of Reporting Trials (CONSORT) statement guid…
2011
The main reason for conducting a clinical trial (CT) is to test the effect of a drug or medical procedure to improve treatment of a disease. CTs contribute most when they are rigorously conducted and the results are published adequately. The aim of this study is to assess, using the CONSORT statement guidelines, the quality of reporting of completed CTs conducted at a tertiary hospital to determine which sections of the articles should be improved. CTs published between 2002 and 2008 were identified by searching the MEDLINE and Cochrane Library. Forty of 127 completed CTs were published. There was a marked increase in the number of articles and the quality of the journals that published the…
