    In order to consider some procedures to prevent errors in radiotherapy based in learned lessons of accidental expositions and in accordance with information contained in international reports elaborated by International Atomic Energy Agency (IAEA) and of the data base availability by the European group Radiation Oncology Safety Information System (ROSIS) on the events, a research of the occurred errors was performed. For the evaluation of the incidents a data base based in the ROSIS and added plus a parameter was created 'type of error'. All the stored data make possible the evaluation of the 839 incidents in terms of frequency of the type of error, the process of detention, the number of reached patients and the degree of severity. Of the 50 types of found errors, the type of error more frequently was 'incorrect treatment coordinate', confirmed with the data of literature and representing 28,96 por cent of the total of the incidents. The results showed 44,44 por cent are discovered at the moment of the treatment and that the process of verification of the fiche or clinical revision of the patient is a verification more occurred insurance and in 43,33 por cent of the searched events. The results indicated that more than 50 por cent of the incidents the severity degree are void and approximately 62 por cent a patient are affected during the accomplishment of the radiotherapy. This work showed that to analyze the data base according to methodology proposal for Klein et al.; for Reason, and Dunscombe et al. is interesting to insert more characteristic detailed in the data base such as: the number of fractions for affected patient, number of fields of treatment for fraction that was affected, shunting line of the prescribed dose and shunting line of the volume prescribed in all the registered in cadastral map events. Some causes exist that can lead the errors when patient they are submitted to the radiotherapy. Some measures can be taken so that

    Il nous reste à étudier une question dont l’intérêt pratique est évident. Sous quelles formes les œuvres historiques se présentent-elles ? Ces formes sont, en fait, très nombreuses : or il en est de surannées ; toutes ne sont pas légitimes ; les meilleures ont des inconvénients. On doit donc se demander, non seulement sous quelles formes les œuvres historiques se présentent, mais quels sont, parmi ceux qui existent, les types d’exposition vraiment rationnels.

  7. Assessment of risks associated to ionizing radiations: lung cancers after domestic radon exposure and thyroid cancers after accidental exposure to radioactive iodines; Evaluation des risques associes aux rayonnements ionisants: cancers du poumon apres exposition domestique au radon et cancers de la thyroide apres exposition accidentelle aux iodes radioactifs

    Catelinois, O

    2004-09-15

    The aim of this work is to develop a critical analysis of quantitative risk assessment in the field of ionizing radiation and to provide new estimates of attributable risks for particular situations of environmental exposure to ionizing radiation. This work is based on knowledge about dose-response relationships and ionizing radiation exposure of the general population. The work focuses on two different situations that both present an important interest for public health: lung cancer associated with domestic radon exposures (natural situation) and thyroid cancer associated with the Chernobyl accident fallout (accidental situation). The assessment of lung cancer risk associated with domestic radon exposure considers 10 dose-response relationships resulting from miner cohorts and case-control studies in the general population. A critical review of available data on smoking habits has been performed and allowed to consider the interactions between radon and tobacco. The exposure data come from measurements campaigns carried out since the beginning of the 1980 by the Institute for Radiation protection and Nuclear Safety and the Health General Directory in France. The French lung cancer mortality data are provided by the I.N.S.E.R.M.. Estimates of the number of attributable cancers are carried out for the whole country, stratified by 8 large regions (Z.E.A.T.) and by 96 departments for the year 1999 allowing to perform a sensibility analysis according to the geographical level of calculation. Uncertainties associated to risk coefficients and exposures have been quantified and it's impact on risk estimates is calculated. The estimated number of deaths attributable to domestic radon exposure ranges from 543 (90% uncertainty interval (U.I.): 75-1,097) to 3,108 (90% U.I.: 2,996-3,221). The corresponding risk fractions range from 2.2% (90% U.I.: 0.3%-4.4%) to 12.4% (90% U.I.: 11.9%-12.8%). The assessment of thyroid cancer risk in the most exposed area of France due to

    Historical accounts of human achievement suggest that accidents can play an important role in innovation. In this paper, we seek to contribute to an understanding of how digital systems might support valuable unpredictability in innovation processes by examining how innovators who obtain value from...... they incorporate accidents into their deliberate processes and arranged surroundings. By comparing makers working in varied conditions, we identify specific factors (e.g., technologies, characteristics of technologies) that appear to support accidental innovation. We show that makers in certain specified...... conditions not only remain open to accident but also intentionally design their processes and surroundings to invite and exploit valuable accidents. Based on these findings, we offer advice for the design of digital systems to support innovation processes that can access valuable unpredictability....

  13. Radiative accidental matter

    Sierra, D Aristizabal; Wegman, D

    2016-01-01

    Accidental matter models are scenarios where the beyond-the-standard model physics preserves all the standard model accidental and approximate symmetries up to a cutoff scale related with lepton number violation. We study such scenarios assuming that the new physics plays an active role in neutrino mass generation, and show that this unavoidably leads to radiatively induced neutrino masses. We systematically classify all possible models and determine their viability by studying electroweak precision data, big bang nucleosynthesis and electroweak perturbativity, finding that the latter places the most stringent constraints on the mass spectra. These results allow the identification of minimal radiative accidental matter models for which perturbativity is lost at high scales. We calculate radiative charged-lepton flavor violating processes in these setups, and show that $\\mu\\to e \\gamma$ has a rate well within MEG sensitivity provided the lepton-number violating scale is at or below $10^6\\,$ GeV, a value (natur...

    Accidental matter models are scenarios where the beyond-the-standard model physics preserves all the standard model accidental and approximate symmetries up to a cutoff scale related with lepton number violation. We study such scenarios assuming that the new physics plays an active role in neutrino mass generation, and show that this unavoidably leads to radiatively induced neutrino masses. We systematically classify all possible models and determine their viability by studying electroweak precision data, big bang nucleosynthesis and electroweak perturbativity, finding that the latter places the most stringent constraints on the mass spectra. These results allow the identification of minimal radiative accidental matter models for which perturbativity is lost at high scales. We calculate radiative charged-lepton flavor violating processes in these setups, and show that μ → eγ has a rate well within MEG sensitivity provided the lepton-number violating scale is at or below 5×105 GeV, a value (naturally) assured by the radiative suppression mechanism. Sizeable τ → μγ branching fractions within SuperKEKB sensitivity are possible for lower lepton-number breaking scales. We thus point out that these scenarios can be tested not only in direct searches but also in lepton flavor-violating experiments.

    Much of the information on the health effects of radiation exposure available to date comes from long-term studies of the atomic bombings in Hiroshima and Nagasaki. Accidental exposures, such as those resulting from the Chernobyl and Kyshtym accidents, have as yet provided little information concerning health effects of ionizing radiation. This paper will present the current state of our knowledge concerning radiation effects, review major large-scale accidental radiation exposures, and discu...

  3. Evaluation of post-accidental rehabilitation strategies

    Post-accidental management aims at restoring acceptable life conditions for population on sanitary, social and economic aspects. It is then a matter for an optimisation process in a multicriteria context, which has to combine quantitative parameters as well as qualitative parameters. In order to fit with this problematic a methodological work has been realised at IPSN. The methodology consists in making a systematic evaluation of indicators in order to provide intercomparing data for many rehabilitation strategies. It relies on four steps: characterisation and formalization of the geographic and demographic environment, radiological diagnosis, selection of countermeasures from a well characterised set of techniques, and last, evaluation of the intercomparing factors. The methodology has been applied to the Becquerel national exercise. Rejects were limited and the contaminated area was less than 2000ha. Conclusions proposed depend on this context. For the selected countermeasures, radiological benefit and some incidences have been calculated: duration of realisation of the counter-measure, materials and human means, worker doses, and amount of generated wastes. In this context, calculations highlighted the importance of external exposition in built areas from the first year after the accident, for most of the reference groups. Ingestion is important only the first year for the highly autarkical level reference groups. Consequently, countermeasures applied to built areas, such as washing of sidewalks, of streets and roofs, or such as trees pruning ,are the most effective for the dosimetric criteria. In agricultural zone, taking off vegetation and ploughing enable to strongly reduce specific activity on food products. Reduction by soil removal is more effective. But here, management problems due to the large amount of generated waste could discard this kind techniques. Countermeasures on milk applied the first year reduce by 3 the dose for highly autarkical level

  14. Accidental inflation in the landscape

    We study some aspects of fine tuning in inflationary scenarios within string theory flux compactifications and, in particular, in models of accidental inflation. We investigate the possibility that the apparent fine-tuning of the low energy parameters of the theory needed to have inflation can be generically obtained by scanning the values of the fluxes over the landscape. Furthermore, we find that the existence of a landscape of eternal inflation in this model provides us with a natural theory of initial conditions for the inflationary period in our vacuum. We demonstrate how these two effects work in a small corner of the landscape associated with the complex structure of the Calabi-Yau manifold P4[1,1,1,6,9] by numerically investigating the flux vacua of a reduced moduli space. This allows us to obtain the distribution of observable parameters for inflation in this mini-landscape directly from the fluxes

  17. Accidental Bolus of Parenteral Nutrition.

    Lodeserto, Frank; Al-Jaghbeer, Mohammed; Huang, David

    2016-08-01

    There is a paucity of data that exists regarding acute toxicity and management in the setting of parental nutrition (PN) overdose. We describe a case of a patient who received an accidental rapid bolus of PN and fat emulsion. She developed a seizure, metabolic acidosis, arrhythmias, myocardial ischemia, altered mental status, hypotension, and hypoxemia likely caused by elevated triglycerides, leading to a hyperviscosity syndrome. After failing standard therapy, she was successfully treated with a single-volume plasma exchange with resolution of symptoms. Fat emulsion or intravenous lipid emulsion and much of its safety have been recently described in its use as a rescue therapy in resuscitation from drug-related toxicity. Elevated serum triglyceride levels can result in a picture similar to a hyperviscosity syndrome. Plasma exchange is a known therapeutic modality for the management of hyperviscosity syndrome and a novel therapy in the treatment of hyperviscosity syndrome due to fat emulsion therapy. In a patient receiving PN with development of rapid deterioration of clinical status, without an obvious etiology, there should be consideration of PN overdose. A rapid assessment and treatment of severe electrolyte abnormalities should be undertaken immediately to prevent life-threatening cardiovascular and central nervous system collapse. If fat emulsion was rapidly coadministered and there are signs and symptoms of hyperviscosity syndrome, then consideration should be given to plasma exchange as an effective therapeutic treatment option.

  18. An accidental poisoning with mitragynine.

    Karinen, Ritva; Fosen, Jan Toralf; Rogde, Sidsel; Vindenes, Vigdis

    2014-10-24

    An increasing number of drugs of abuse are sold word wide over the internet. Names like "legal highs", "herbal highs" etc. give the impression that these are safe products, although the risk of fatal reactions might be substantial. Leaves from the plant Mitragyna speciosa, contain active compounds like mitragynine and 7-hydroxymitragynine. It has been reported that the potency of 7-hydroxymitragynine at the μ-opioid receptor is 30 times higher than that of mitragynine and 17 times higher than that of morphine. Case reports regarding poisoning with Kratom are reported, but the toxic or lethal ranges for the concentrations of the active substances have not been established, and concentrations of 7-hydroxymitragynine have not been reported previously. We present a case report where a middle aged man was found dead at home. The deceased had a history of drug abuse and mental illness for several years. At autopsy, there were no significant pathological findings. Post-mortem analysis of peripheral blood revealed: zopiclone 0.043mg/L, citalopram 0.36mg/L and lamotrigine 5.4mg/L, i.e. concentrations regularly seen after therapeutic ingestion of these drugs. Additionally mitragynine 1.06mg/L and 7-hydroxymitragynine 0.15mg/L were detected in blood and both also in urine. The high concentrations of mitragynine and 7-hydroxymitragynine indicate that the cause of death is intoxication by these substances; and the circumstances point toward the manner of death being accidental. We recommend that both mitragynine and 7-hydroxymitragynine are analyzed for in cases with suspected Kratom intoxication. PMID:25453780

    Full Text Available La mortalidad global por accidente cerebrovascular (ACV ha disminuido en las últimas tres décadas, probablemente debido a un mejor control de los factores de riesgo vascular. La mortalidad hospitalaria por ACV ha sido tradicionalmente estimada entre 6 y 14% en la mayoría de las series comunicadas. Sin embargo, los datos de ensayos clínicos recientes sugieren que esta cifra sería sustancialmente menor. Se revisaron datos de pacientes internados con diagnóstico de ACV del Banco de Datos de Stroke de FLENI y los registros institucionales de mortalidad entre los años 2000 y 2010. Los subtipos de ACV isquémicos se clasificaron según criterios TOAST y los ACV hemorrágicos en hematomas intrapanquimatosos, hemorragias subaracnoideas aneurismáticas, malformaciones arteriovenosas y otros hematomas intraparenquimatosos. Se analizaron 1514 pacientes, 1079 (71% con ACV isquémico (grandes vasos 39%, cardioembólicos 27%, lacunares 9%, etiología indeterminada 14%, otras etiologías 11% y 435 (29% con ACV hemorrágico (intraparenquimatosos 27%, hemorragia subaracnoidea 30%, malformaciones arteriovenosas 25% y otros hematomas espontáneos 18%. Se registraron 38 muertes intrahospitalarias (17 ACV isquémicos y 21 ACV hemorrágicos, representando una mortalidad global del 2.5% (1.7% en ACV isquémicos y 4.8% en ACV hemorrágicos. No se registraron muertes asociadas al uso de fibrinolíticos endovenosos. La mortalidad intrahospitalaria en pacientes con ACV isquémico y hemorrágico en nuestro centro fue baja. El manejo en un centro dedicado a las enfermedades neurológicas y el enfoque multidisciplinario por personal médico y no médico entrenado en el cuidado de la enfermedad cerebrovascular podrían explicar, al menos en parte, estos resultados.

  1. Demonstration of the astral post accidental code

    Full text: Should an important release of radionuclides occur in the environment, one would quickly have to assess radionuclide concentration in media and foodstuff, deduce the potential exposition of concerned populations to the radiations, predict the evolution of the situation and propose different scenarios of managing the contaminated zones. To achieve this, the ASTRAL code was created, which can be used by a relatively large group of people composing crisis centers or making predictive impact studies. The starting point of the assessments is the ground deposit of radionuclides: the atmospheric dispersion phase and the cloud exposure are not taken into account here. The calculations achieved concern time evolution of radionuclide concentration in elements of the agricultural and forest food chain as well as assessment of doses due to external and internal exposure. These values are compared to regulation limits and/or intervention levels. Different simulations of contaminated zones management can be led by applying counter-measures, dispositions meant to reduce the accident's impact an environment and populations. The seventy radionuclides taken into account in the present version are some of those met in case of accidents or during the exploitation of a Pressurized Water Reactor (PWR). They relates to 37 elements that are : Ag, Am, Ba, Br, Cd, Ce, Cl, Cm, Co, Cr, Cs, Eu, Fe, I, Ir, La, Mn, Mo, Nb, Nd, Ni, Np, Pm, Pr, Rb, Rh, Ru, Sb, Sm, Sn, Sr, Tc, Te, Y, Zn, Zr. On a temporal point of view, the predictions extend to 3 years after the deposition. The starting point of calculations, deposits on the ground, can be issued from field measurements or predicted by a code - especially in an early phase when deposits are expected but have not occurred. Such predictions are performed by CONRAD, the atmospheric dispersion tool developed by IRSN for its Crisis Technical Center. A link in ASTRAL has been developed to fetch CONRAD's results and Input them in its database

  2. Lung nodules accidentally detected on CT scans

    Improving of the spatial resolution of modern CT scanners has increased the amount of information obtained by lung CT, and thus the amount of accidentally determined nodules and quality of their structure specification. To unify the criteria of their follow-up CT studies Fleischner Society has issued recommendations for management of solid pulmonary nodules, and then added recommendations for subsolid nodules. In this article the review of categories of such accidental findings in lungs is presented with follow-up criteria and annotations applied

  13. Ethnographic museum exposition as a function of communication process: An example of the permanent exposition in the Ethnographic museum in Belgrade

    Stojanović Marko

    2007-01-01

    Full Text Available Research about the meanings of the permanent exposition in the Ethnographic museum in Belgrade, which communication-wise points to the individual cultural projects as a function of incorporating and establishing specific viewpoints into one's own cultural system. Within developments of museum logy science, which resulted as a recent museum exposition, can be seen the ways and byways of the pre-memocentric expographic model. Three floors where the exposition was placed indicate multi-layered ideationally-conceptual syndrome, which - based on specific and inadvertent messages - point to several segments in real and symbolic space for communication between exposition's author and consumers. As a function of cultural mediators, authors present objects which represent public communication space as opposed to the objects from the private communication space. Such approach points to the functional symbolic reality of two models - proclaimed mainstream as a function of wanted model and everyday functional model of conduct. That way semantic premise is underlined, which in each community separates communication channels into mythologized stereotyped and prejudiced semantic space and realistic existence.

  15. Accidental Kähler moduli inflation

    We study a model of accidental inflation in type IIB string theory where inflation occurs near the inflection point of a small Kähler modulus. A racetrack structure helps to alleviate the known concern that string-loop corrections may spoil Kähler Moduli Inflation unless having a significant suppression via the string coupling or a special brane setup. Also, the hierarchy of gauge group ranks required for the separation between moduli stabilization and inflationary dynamics is relaxed. The relaxation becomes more significant when we use the recently proposed D-term generated racetrack model

  17. Accidental gamma dose measurement using commercial glasses.

    Narayan, Pradeep; Vaijapurkar, S G; Senwar, K R; Kumar, D; Bhatnagar, P K

    2008-01-01

    Commercial glasses have been investigated for their application in accidental gamma dose measurement using Thermoluminescent (TL) techniques. Some of the glasses have been found to be sensitive enough that they can be used as TL dating material in radiological accident situation for gamma dosimetry with lower detection limit 1 Gy (the dose significant for the onset of deterministic biological effects). The glasses behave linearly in the dose range 1-25 Gy with measurement uncertainty +/- 10%. The errors in accidental dose measurements using TL technique are estimated to be within +/- 25%. These glasses have shown TL fading in the range of 10-20% in 24 h after irradiation under room conditions; thereafter the fading becomes slower and reaches upto 50% in 15 d. TL fading of gamma-irradiated glasses follows exponential decay pattern, therefore dosimetry even after years is possible. These types of glasses can also be used as lethal dose indicator (3-4 Gy) using TL techniques, which can give valuable inputs to the medical professional for better management of radiation victims. The glasses are easy to use and do not require lengthy sample preparation before reading as in case of other building materials. TL measurement on glasses may give immediate estimation of the doses, which can help in medical triage of the radiation-exposed public. PMID:18285317

  18. Medical management of accidentally exposed individuals

    Bone marrow aplasia is one of the main syndromes following a high dose accidental radiation exposure. Whilst transfusion and bone marrow transplantation have been used with some success starting with the first treatments of accident victims, other therapeutic strategies are needed. With the development of experimental and clinical haematology, promising new approaches to the treatment of aplasia have appeared. New trends for the treatment of haemopoietic injury based on bone marrow transplantation rely on new sources of compatible donor cells, such as cord blood, on the selection of immature haemopoietic cells and on new transplant regimens. Haemopoietic growth factors stimulate the proliferation and/or differentiation of haemopoietic progenitors and, possibly, stem cells. Furthermore, they act on the functions of mature cells. Currently, they have specific uses in haematology related to their role in the regulation of growth and in the differentiation of haemopoietic progenitor cells. Growth factors have already been used for the treatment of accidental radiation induced aplasia and lessons have been learned from their medical management and followup. (author)

  20. Accidental radioisotope burns - Management of late sequelae

    Varghese Bipin

    2010-10-01

    Full Text Available Accidental radioisotope burns are rare. The major components of radiation injury are burns, interstitial pneumonitis, acute bone marrow suppression, acute renal failure and adult respiratory distress syndrome. Radiation burns, though localized in distribution, have systemic effects, and can be extremely difficult to heal, even after multiple surgeries. In a 25 year old male who sustained such trauma by accidental industrial exposure to Iridium192 the early presentation involved recurrent haematemesis, pancytopenia and bone marrow suppression. After three weeks he developed burns in contact areas in the left hand, left side of the chest, abdomen and right inguinal region. All except the inguinal wound healed spontaneously but the former became a non-healing ulcer. Pancytopenia and bone marrow depression followed. He was treated with morphine and NSAIDs, epidural buprinorphine and bupivicaine for pain relief, steroids, antibiotics followed by wound excision and reconstruction with tensor fascia lata(TFL flap. Patient had breakdown of abdominal scar later and it was excised with 0.5 cm margins up to the underlying muscle and the wound was covered by a latissimis dorsi flap. Further scar break down and recurrent ulcers occurred at different sites including left wrist, left thumb and right heel in the next two years which needed multiple surgical interventions.

  4. Accidental Turbulent Discharge Rate Estimation from Videos

    Ibarra, Eric; Shaffer, Franklin; Savaş, Ömer

    2015-11-01

    A technique to estimate the volumetric discharge rate in accidental oil releases using high speed video streams is described. The essence of the method is similar to PIV processing, however the cross correlation is carried out on the visible features of the efflux, which are usually turbulent, opaque and immiscible. The key step in the process is to perform a pixelwise time filtering on the video stream, in which the parameters are commensurate with the scales of the large eddies. The velocity field extracted from the shell of visible features is then used to construct an approximate velocity profile within the discharge. The technique has been tested on laboratory experiments using both water and oil jets at Re ~105 . The technique is accurate to 20%, which is sufficient for initial responders to deploy adequate resources for containment. The software package requires minimal user input and is intended for deployment on an ROV in the field. Supported by DOI via NETL.

  5. Throat-cutting of accidental origin.

    Demirci, Serafettin; Dogan, Kamil Hakan; Gunaydin, Gursel

    2008-07-01

    Incised wounds of the neck can be accidental, homicidal, or suicidal. In this paper, a death case has been presented where a spinning circular saw of a cutting machine in a workshop came off its place and cut the throat of a 30-year-old male who was operating the machine. There was an incision (15 cm x 5 cm) that began in the middle of the neck down the thyroid cartilage, extended horizontally to the left of the neck and ended on the outer part of the neck in the outer left side of m. trapezius. Death occurred because of exsanguination caused by the cutting of carotis artery and jugular vein. In the case we presented, although the cut in the neck initially suggested homicide, it was found to have occurred as a result of an accident after the autopsy and death scene investigation.

  7. Accidental etizolam ingestion in a child.

    Kato, Zenichiro; Nakamura, Mitsuhiro; Funato, Michinori; Kuwabara, Hideaki; Kondo, Naomi

    2007-07-01

    Etizolam (ETZ) is an antidepressive thienodiazepine drug that is used worldwide. The most frequent adverse effects in adults are drowsiness and muscle weakness, and this can rarely cause paradoxical excitation; however, no information exists on intoxication in children. Furthermore, evidence bearing on its safety in children is not available. We present a case of a child who accidentally took a single dose of ETZ, approximately the same as a therapeutic dose for adults, and who showed paradoxical excitation and muscle weakness. The case presented here suggests that pediatricians and emergency physicians should be aware of the possible adverse effects in children and therapeutic approaches in intoxication of ETZ and the necessity of further investigations on a specific therapeutic guideline for overdose management especially in children.

    Bröning, Sonja; Sack, Peter-Michael; Thomsen, Monika; Thomasius, Rainer

    2016-09-01

    Children with Multiple Risk Factor Exposition Benefit from the German "Strengthening Families Program" The German adaptation of the substance use-preventive family-based Strengthening Families Program 10-14 (SFP, Iowa version) was evaluated in a longitudinal two-year follow-up trial. Participants were N = 292 children with a mean age of twelve years at baseline, and N = 292 parents. We employed a multi-centric, randomized-controlled, two-armed (SFP vs. minimal control condition) study design. Following a "risk moderation hypothesis", we assumed that children with an elevated risk-exposition R(+) would benefit more than children with a low risk-exposition R(-) irrespective of the preventive intervention, and that R(+) under SFP would benefit more than R(+) under the minimal control condition. "Risk-exposition" was measured in correspondence with the Communities That Care Youth Survey-questionnaire. A total of 28 % of children were classified with an elevated risk level. Children's reports confirmed our hypothesis: R(+) report a total of eleven improvements, four of these being significantly more distinct than in the other groups (Anxiety-Depressivity, Punitive Parenting of mother, Punitive Parenting of father, Unbalanced family functioning). In three measures an improvement appears solely in R(+) under SFP (Satisfaction with family functioning, School Attachment and Peer Relationship Quality, Quality of Life). Parents' reports showed a similar tendency, but were less pronounced. PMID:27595812

  15. The expositive discourse as pedagogical discourse: studying recontextualization in the production of a science museum exhibition

    Marandino, Martha

    2016-06-01

    In this paper I report on the sociological and educational particulars of The Biodiscovery Space exhibition of the Life Museum of the Oswaldo Cruz Foundation in Rio de Janeiro, Brazil, using Basil Bernstein's framework of pedagogic discourse and recontextualization. Data for analysis was obtained from interviews with the exhibition developers, field observations of museum visitors and analysis of exhibition documents. Using the ideas of power, classification and framework, among others, I analyzed the recontextualization process of the production of expositive discourse. Thus, working with Bernstein's idea of classification, I explain the relationship between the discourses of the science of biology, history of science, museology, education, and communication in order to produce an expositive discourse. I also make explicit how agents of the Official Recontextualization Field of the Museum and the Pedagogic Recontextualization Field "....of the Museum determine partly the final expositive discourse of an exhibition". Using the idea of a pedagogic discourse framework, I discuss how the constraints imposed by objects and texts in exhibitions help to create a specific manner of visitor interaction with these elements, "even if they have some autonomy". Considerations about the audience and the intended process of acquisition are presented, when I discuss the control strategies of the exhibition. I propose that the Biodiscovery Space exhibit has a visible pedagogy. Finally, using the collected data I discuss the power tensions created in the production of expositive discourse showing how distributive, recontextualization and evaluation rules work in the context of exhibitions. The study of the dynamics in forming the expositive discourse using Bernstein's framework reveals the individuals and institutions, the selection criteria, the negotiations and the power relations involved. It has the potential to assist both educators and researchers in the museum education

The study of the dynamics in forming the expositive discourse using Bernstein's framework reveals the individuals and institutions, the selection criteria, the negotiations and the power relations involved. It has the potential to assist both educators and researchers in the museum education

  18. Inactivation of Candida albicans by Corona Discharge: The Increase of Inhibition Zones Area After Far Subsequent Exposition

    Vladyslava Fantova

    2013-01-01

    Full Text Available The cold atmospheric pressure plasma generated by the negative corona discharge has inhibition effect on the microorganism growth. This effect is well-known and it can be demonstrated on the surface of cultivation agar plates by the formation of inhibition zones. We exposed the cultures of Candida albicans to the negative corona discharge plasma in a special arrangement in this study: The equal doses of plasma were applied subsequently twice or four times on the same culture on one Petri dish, while the distance between exposed points was variable. Only small differences were observed in decontaminated zone areas for twice exposed agar at the shortest distance between exposed points (1.5 cm. In case of the four times exposed agars, we observed significant differences in inhibition zone areas, dependent not only on the exposition site distances, but also on the exposition order. The largest inhibition zone size was observed for the first exposition decreasing to the fourth one. To check relevancy of these dependencies, we presume to conduct further set of experiments with lower yeast concentration. In conclusion, significant difference in partial inhibition zone sizes appeared only when four expositions on one Petri dish were carried out, whereas no significant difference was observed for two subsequent expositions. The explanation of this effect may be the subject of subsequent remote exposition(s, when minute amounts of scattered active particles act on the previously exposed areas; the influence of diffused ozone may also take place.

  19. Static and mobile networks design for atmospheric accidental releases monitoring

    The global context of my PhD thesis work is the optimization of air pollution monitoring networks, but more specifically it concerns the monitoring of accidental releases of radionuclides in air. The optimization problem of air quality measuring networks has been addresses in the literature. However, it has not been addresses in the context of surveillance of accidental atmospheric releases. The first part of my thesis addresses the optimization of a permanent network of monitoring of radioactive aerosols in the air, covering France. The second part concerns the problem of targeting of observations in case of an accidental release of radionuclides from a nuclear plant. (author)

  6. Etica ed evoluzionismo: la proposta di Marc Hauser

    Irene Pilloni

    2013-11-01

    Full Text Available Le recenti scoperte nell’ambito della psicologia evoluzionistica potrebbero offrire una risposta al dibattito sull’origine evoluzionistica della facoltà morale dell’Homo sapiens. In passato, il tentativo di spiegare il comportamento morale a partire dalla teoria dell’evoluzione è stato intrapreso dal padre fondatore dell’evoluzionismo Charles Darwin, successivamente da T.H. Huxley e da H. Spencer e infine dal sociobiologo E. Wilson a metà degli anni ‘70 del Novecento. Oggi questa impresa è stata ereditata dallo psicologo evoluzionista Marc Hauser, le cui indagini prendono avvio da un’analogia tra facoltà morale e facoltà linguistica. Questa analogia gli consente di affermare che la pluralità di codici morali adottati dagli uomini nelle differenti culture dipende da un numero limitato di principi morali, nello stesso modo in cui la varietà di lingue con cui gli uomini si esprimono, dipende da un numero limitato di principi linguistici universali. Dunque, sembrerebbe che l’evoluzione biologica abbia plasmato dei principi morali universali e uniformi che si presentano costanti in tutti gli uomini a prescindere dalla loro appartenenza culturale. Come vadano intesi i principi morali universali e quale rapporto intercorre tra di essi e i vari codici morali sarà l’argomento di questo saggio, il quale tenterà di analizzare la proposta di Marc Hauser all’interno della cornice dei rapporti tra etica ed evoluzionismo.

  17. Lessons learned from accidental exposures in radiotherapy

    The medical use of radiation is unique in that patients are intentionally exposed to radiation. The aim in radiation therapy is twofold: to deliver a dose and dose distribution that is adequate for tumour control, but which also minimizes complications in normal tissues. In therapeutic applications, the doses are high and a deviation from the prescribed dose may have severe or even fatal consequences. There is therefore a great need to ensure adequate radiation protection and safety in radiotherapy by verifying that all personnel involved are appropriately trained for their duties, that the equipment used meets relevant international specifications for radiation safety and that safety culture is embedded in routine activities in radiotherapy departments. Many individuals must interact and work together on highly technical measurements and calculations, and therefore the potential for mistakes is great. A review of the mistakes shows that most are due to human error. The International Basic Safety Standards for Protection against Ionizing Radiation and the Safety of Radiation Sources (IAEA Safety Series No. 115) require that a prompt investigation be conducted whenever an accidental medical exposure of patients occurs. The report of the investigation is to be disseminated to the appropriate parties so that lessons can be learned to prevent similar accidents or mitigate their consequences in the future. This Safety Report is a collection of a large number of events that may serve as a checklist against which to test the vulnerability of a facility to potential accidents, and to provide a basis for improving safety in the use of radiation in medical applications. A further purpose of this report is to encourage readers to develop a questioning and learning attitude, adopt measures for the prevention of accidents, and prepare for mitigation of the consequences of accidents if they occur

  18. Accidental oil spills - project management strategy

    Planning and organisation, as well as actions taken during accidental discharging of hazardous substances (hydrocarbons) into the soil and water, show that without integrating all the functions of safety, occupational safety, fire and explosion protection, technical safety, all the way to the environmental protection, procedure of cleaning, rehabilitation and remediation of polluted areas into their original state cannot be successfully carried out. Neglecting any of the mentioned links/components of the procedure represents a risk to people's health and life, while pollution to the environment remains a constant threat. Development of technologies is quickly transforming the environment in which the professionals of all disciplines work. Therefore, the response to changes by application of new technologies and procedures in all domains is indispensable, however, through a comprehensive and expert perception and consideration of each of the essential correlations comprising the safety management in all the fields. Through management of safety projects in environmental protection, it has become obvious that a united management of different fields is necessary, as well as management of safety in general. Engineering, health, legislation, public, environmental standards, occupational safety, hazards, biophysical and socio-economic aspects are parts of an integral management. Experts joined efforts through interaction and communications are inter-disciplinary characteristics, i.e. multi-disciplinary safety management, but also the management of each project separately. Exactly this knowledge exchange is highly productive and becomes an indispensable element in recognition of indirect and cumulative actions, thus applicable in any field. Implementation of European standards and accreditation of procedures pursuant to the corresponding standards, from risk assessment through rehabilitation to independent expert confirmation of efficiency in implementing the entire

  19. [Severe accidental hypothermia in an elderly woman].

    Knobel, B; Mikhlin, A

    2001-11-01

    Profound hypothermia (core temperature of less than 28 degrees C) is a life threatening state and a medical emergency associated with a high mortality rate. The prognosis depends on underlying diseases, advanced or very early age, the duration prior to treatment, the degree of hemodynamic deterioration, and especially, the methods of treatment, including active external or internal rewarming. This is a case study of an 80-year-old female patient with severe accidental hypothermia (core temperature 27 degrees C). She was found in her home lying immobile on the cold floor after a fall. The patient was in a profound coma with cardiocirculatory collapse, and the medical staff treating her was inclined to pronounce her deceased. On her arrival at the hospital, she was resuscitated, put on a respirator and actively warmed. Very severe metabolic disorders were found, including a marked metabolic acidosis composed of diabetic ketoacidosis (she had suffered from insulin treated type 2 diabetes mellitus) and lactic acidosis with a very high anion gap (42) and a hyperosmotic state (blood glucose 1202 mg/dl). There were pathognomonic electrocardiographic abnormalities, J-wave of Osborn and prolonged repolarization. Slow atrial fibrillation with a ventricular response of 30 bpm followed by a nodal rhythm of 12 bpm and reversible cardiac arrest were recorded. The pulse and blood pressure were unobtainable. Despite the successful resuscitation and hemodynamic and cognitive improvement, rhabdomyolysis (CKP 6580 u/L), renal failure and hepatic damage developed. She was extubated and treated with intravenous fluids containing dopamine, bicarbonate, insulin and antibiotics. Her medical condition gradually improved, and she was discharged clear minded, functioning very well and independent. Renal and liver tests returned eventually to normal limits. Progressive bradycardia, hypotension and death due to ventricular fibrillation or asystole commonly occur during severe hypothermia

    middle-income country (LMIC) settings. In this paper, we aim to establish cause structure for accidental deaths in children aged 0-4 years in China in the year 2010. METHODS: In this paper, we explored the database of 208 multi-cause child mortality studies in Chinese that formed a basis for the first...... deaths. We identified 71 further studies that provided specific causes for accidental deaths. We used epidemiological modeling to estimate the number of accidental child deaths in China in 2010 and to assign those deaths to specific causes. RESULTS: In 2010, we estimated 314 581 deaths in children 0......-4 years in China, of which 31 633 (10.1%) were accidental. Accidental deaths contributed 7240 (4.0%) of all deaths in neonatal period, 8838 (10.5%) among all post-neonatal infant deaths, and 15 554 (31.7%) among children with 1-4 years of age. Among four tested models, the most predictive was used to...

  1. Cost of accidental carbon monoxide poisoning: A preventable expense.

    Hampson, Neil B

    2016-06-01

    Carbon monoxide (CO) poisoning is common in the United States, accounting for hundreds of deaths and thousands of emergency department visits annually. It is believed that most accidental CO poisoning is preventable through public education, warning labels on consumer products, and uniform use of residential CO alarms. However, cost effectiveness of these prevention strategies has not been demonstrated in the United States to date. It was the objective of this study to estimate societal cost of accidental CO poisoning and evaluate the cost-effectiveness of universal installation of residential CO alarms. Published studies and data from the English language literature were used in to estimate direct hospital costs and lost earnings resulting from accidental CO poisoning. The study was performed in the US in 2015. Approximately 6600 individuals are estimated to sustain long-term cognitive sequela annually, with total loss in earnings of approximately $925 million, 334 individuals die from accidental, non-fire related CO poisoning with an average loss of 26 years of productivity accounting for $355 million, and 2800 are hospitalized with acute medical care costs of $33 million. Available data indicate that accidental CO poisoning in the US conservatively costs society over $1.3 billion, resulting from direct hospital costs and lost earnings. Further, it demonstrates a positive cost-benefit ratio for the uniform use of residential CO alarms. PMID:26844181

  4. Residues of maneb in potatoes and lettuce and their persistence during cooking, washing and uv exposition

    Lettuce plants were treated each with 0,186 mg of 14C maneb and 1,86 mg unlabelled maneb. The plants were analyzed 30 days later and subjected to washing. Washing eliminates 17,46% of total 14C maneb applied. No Etu was observed in water.Washing and baking cause a significant decrease of EBDC in potatoes samples and the UV exposition involves a decrease of the fungicide and a formation of Etu. On the other hand 54 % and 38% of lettuce and potatoe samples analyzed by CS2 method exceed the authorized norms

  5. Un discret choc des cultures. L’exposition occidentale de l’exotique

    Alcalde, Maxence

    2014-01-01

    Dans les années 1980-1990, plusieurs expositions ont entrepris de questionner les rapports entre art « occidental » et art « non-occidental ». Chacune des ces tentatives curatoriales revenait sur les relations plus ou moins fantasmées entre ces pratiques artistiques, sans toutefois parvenir à en formuler une version claire. Etrangement, c’est peut-être chez Quatremère de Quincy (1755-1849) que se trouve la clef du rapport mis à l’épreuve par ces récentes présentations.

  7. Correcting for accidental correlations in saturated avalanche photodiodes

    Grieve, James A; Tang, Zhongkan; Ling, Alexander

    2015-01-01

    In this paper we present a high-level numerical model for estimating rates of accidental correlations between a pair of passively quenched Geiger mode avalanche photodiodes operating in the saturated regime. By considering the recovery time of both the diodes and the detection circuit we introduce the concept of an "effective duty cycle" and show that it may be estimated by numeric simulation. The impact of effective duty cycle on the observed accidental rate is examined and we demonstrate that the updated model leads to an improved correction factor in actual experiments. This will improve the signal-to-noise ratio in applications depending on correlation measurements.

  8. Accidental ingestion of a fractured Twin-block appliance.

    Rohida, Neeraj S; Bhad, Wasundhara A

    2011-01-01

    Orthodontic appliances that become dislodged can cause problems in the airway or the gastrointestinal tract. Accidental ingestion of an appliance during a chair-side procedure or because of inadequate retention of the appliance can create a medical emergency with potentially serious complications, including death from aspiration of the foreign body. This article reports the accidental ingestion of a fractured Twin-block appliance. The ease with which removable appliances can become dislodged if retention is inadequate is discussed, and some serious complications that can arise are described. Precautions the orthodontist can take to prevent such accidents are presented. PMID:21195285

  9. Exposition index calculation from different points in a gamma sterilization plant radiation room

    Radiation fields produced by a JS-6500 rectangular irradiator source were evaluated. Knowledge of the values of these fields is necessary in irradiation and health physics processes. Techniques for evaluating the dose rates from puntual, linear and plane sources were applied and computer programs for the three sources designed. Fricke, cupric-ferrous and red acrilic dosimetric systems were used, to verify the eight points located along the interior walls of the irradiation room, around the source with 936, 987 Ci of Co-60 (1st-March 1980). When considering the distance between the source and each point of interest the calculated exposition indexes obtained were practically the same for the three source types and were up to 35% greater than the experimental values; in contrast when absorption and buildup of the source were taken in to account, the experimental values were higher than the calculated ones by up to 16%, this in estimating the produced exposition index for a rectangular source at least there two parameters should be included.

  10. Reasons between effective doses for tomographic and mathematical models due to external exposition by photons

    The development of Monte Carlo codes and new and sophisticated tomographic human models, or based on voxel, motivated the ICRP to propose a revision of the traditional exposition models, which have been used to calculate doses on organs and tissues using mathematical phantoms MIRD-type 5. This article presents calculations made with tomographic phantoms MAX (Male Adult voXel) and FAX (Female Adult voXel), recently developed and also, for comparison, with ADAM and Eve mathematician phantoms. All models were coupled to the EGS4 and MCNP4 codes for full body external irradiation by photons. It were simulated expositions AP, PA and rotational for energies varying between 10 keV and 10 MeV. The effective calculated doses were compared separately to evaluate: the replacement of the Monte Carlo code; the composition of the tissues and the replacement of tomographic phantoms by mathematical ones. Effective doses calculated results indicate that for external exposures by photons to introduce models based on voxels can cause a reduction of about 10% to the energies considered in this study

  13. Are diabetic foot lesions precipitated by accidental trauma?

    Doshi, H K; Moissinac, K; Harwant, S

    2001-12-01

    Diabetic foot lesions may arise from frictional trauma due to tight or inappropriate footwear, repetitive stresses on parts of the foot, overlying bony prominence generated by walking and accidental trauma to the neuropathic foot. Many diabetics have been found to be unaware of their foot lesion, or know what the precipitating cause was. Based on the assumption that accidental trauma would affect the foot in a random fashion and result in lesions distributed evenly throughout the foot, a study was performed to determine whether foot lesions were distributed evenly or concentrated to certain areas of predilection. It was found that foot lesions were not evenly distributed but concentrated to certain areas of predilection. Even though relatively high proportion of the study population walked about in open slippers and barefeet, the study showed that accidental trauma was not a predominant precipitant of diabetic foot lesions. Diabetic foot lesions tend to occur as a result of cumulative, repetitive trauma to areas of prediliection rather than accidental trauma. PMID:14569763

  1. Radiologist's exposition during the radioscopy of the digestive tract in esophagus-gastro-duodenum studies

    The results of personal dosimetry confirm that one of the most exposed groups to the ionizing radiations is those of Radiologists who work with radioscopy of the digestive tract. However, the particular conditions of the exposition complicate the interpretation of the reading for the values obtained on the dosimeter. In order to improve such interpretation, it has done simultaneous measurements with the routine dosimeter and with thermoluminescent dosimeters (TLD) of lithium fluoride(LiF). It has selected eight places on the worker's body and located such dosimeters, so that the dose was integrated during thirty studies. It could verify that, if the dosimeter is located in agreement with the recommendations of the International Commission of Radiological Protection(ICRP), the reading overestimates in several times the dose in whole body(or effective dose). It has also considered that the amount of such procedures done by the radiologist is limited in this case, by the effective dose

  2. Additive combinatorics: with a view towards computer science and cryptography - An exposition

    Bibak, Khodakhast

    2011-01-01

    Recently, additive combinatorics has blossomed into a vibrant area in mathematical sciences. But it seems to be a difficult area to define; maybe because of a blend of ideas and techniques from several seemingly unrelated contexts which are used there. One might say that additive combinatorics is a branch of mathematics concerning the study of additive structures in sets equipped with a group structure; and perhaps other structure that interacts with the group structure. This newly emerging field has seen tremendous advancements over the last few years, and has recently become a focus of attention amongst both mathematicians and computer scientists. This fascinating area has been enriched by its formidable links to combinatorics, number theory, harmonic analysis, ergodic theory, and some other branches; all deeply cross-fertilize each other holding great promise for all of them! There is a considerable number of incredible problems, results, and novel applications in this thriving area. In this exposition, we...

    Palmira PECIULIAUSKIENE

    2007-10-01

    Full Text Available Changes in educational technologies modify the role of the teacher and require new competencies. Scientific literature describes competence in using ICT as the wholeness of two structural components - basic and educational ICT competence. The conception has been considered conducting research on would-be teachers' competence in applying ICT. The article deals with the exposition of would-be teachers' competence in applying ICT in the process of teaching practice and focuses on the impact of studying informatics in forms 11 and 12 on the development of the latter competence. Research disclosed that would-be teachers had fully mastered ordinary abilities demonstrating basic and educational competencies in ICT. The development of would-be teachers' competence has been accepted as a permanent process starting yet before the studies at university within the process of learning informatics in forms 11 and 12.

  5. Exposition of the operator's eye lens and efficacy of radiation shielding in fluoroscopically guided interventions

    Purpose: Efficacy of radiation protection tools for the eye lens dose of the radiologist in fluoroscopic interventions. Materials and Methods: A patient phantom was exposed using a fluoroscopic system. Dose measurements were made at the eye location of the radiologist using an ionization chamber. The setting followed typical fluoroscopic interventions. The reduction of scattered radiation by the equipment-mounted shielding (undercouch drapes and overcouch top) was evaluated. The ceiling-suspended lead acrylic glass screen was tested in scattered radiation generated by a slab phantom. The protective properties of different lead glass goggles and lead acrylic visors were evaluated by thermoluminescence measurements on a head phantom in the primary beam. Results: The exposition of the lens of about 110 to 550 μSv during radiologic interventions is only slightly reduced by the undercouch drapes. Applying the top in addition to the drapes reduces the lens dose by a factor of 2 for PA projections. In 25 LAO the dose is reduced by a factor between 1.2 and 5. The highest doses were measured for AP angulations furthermore the efficacy of the equipment-mounted shielding is minimal. The ceiling-suspended lead screen reduced scatter by a factor of about 30. The lead glass goggles and visors reduced the lens dose up to a factor of 8 to 10. Depending on the specific design, the tested models are less effective especially for radiation from lateral with cranial angulation of the beam. Occasionally the visors even caused an increase of dose. Conclusion: The exposition of the eye lens can be kept below the new occupational limit recommended by the ICRP if the radiation shielding equipment is used consistently. (orig.)

  6. Accidental intraoral injection of formalin during extraction: case report.

    Swami, Pushp Chander; Raval, Rushik; Kaur, Mandeep; Kaur, Jasleen

    2016-04-01

    Transparent, clear solutions such as hydrogen peroxide, alcohol, sodium hypochlorite, formaldehyde, and local anaesthetics are widely used in dentistry, so the tissues are liable to accidental injury. Formalin, a 37%-40% solution of formaldehyde, is extensively used in 10% solution as a tissue preservative, but it has toxic effects on systems such as the gastrointestinal tract, respiratory tract, skin, and mucosa. However, we know of few reports of cases of inadvertent injection of alcohol and formalin directly into the human body. In this case report we describe the early and delayed clinical effects of accidental intraoral injection of formalin, the subsequent symptoms and management, and some prudent points that should be learnt to avoid such incidents in the future.

  7. Leading global projects for professional and accidental project leaders

    Moran, Robert T

    2008-01-01

    This book is a must-read for anyone responsible for projects and initiatives that span functional and geographical divides. Authors Moran and Youngdahl bring extensive experience and learning from industry practice to present a clear and straightforward treatment of the leadership skills and knowledge required to lead projects that are global in nature. They have written the first book of its kind to address the three essential skills of global project leaders - strategic project management, project leadership, and cross-cultural leadership. The authors argue that global project leadership is an essential skill in our project-based world and that we are all either intentional or accidental project leaders. Intentional project leaders pursue formal project management education and even certification whereas accidental project leaders find themselves leading global projects and initiatives as a result of a special assignment or promotion. Moran and Youndahl have found that the vast majority of global projects ...

  8. Accidental degeneracy of double Dirac cones in a phononic crystal

    Chen, Ze-Guo

    2014-04-09

    Artificial honeycomb lattices with Dirac cone dispersion provide a macroscopic platform to study the massless Dirac quasiparticles and their novel geometric phases. In this paper, a quadruple-degenerate state is achieved at the center of the Brillouin zone in a two-dimensional honeycomb lattice phononic crystal, which is a result of accidental degeneracy of two double-degenerate states. In the vicinity of the quadruple-degenerate state, the dispersion relation is linear. Such quadruple degeneracy is analyzed by rigorous representation theory of groups. Using method, a reduced Hamiltonian is obtained to describe the linear Dirac dispersion relations of this quadruple-degenerate state, which is well consistent with the simulation results. Near such accidental degeneracy, we observe some unique properties in wave propagating, such as defect-insensitive propagating character and the Talbot effect.

  12. Paediatric femur fractures at the emergency department: accidental or not?

    Hoytema van Konijnenburg, Eva M M; Vrolijk-Bosschaart, Thekla F; Bakx, Roel; Van Rijn, Rick R

    2016-01-01

    Only a small proportion of all paediatric fractures is caused by child abuse or neglect, especially in highly prevalent long bone fractures. It can be difficult to differentiate abusive fractures from non-abusive fractures. This article focuses on femoral fractures in young children. Based on three cases, this article presents a forensic evidence-based approach to differentiate between accidental and non-accidental causes of femoral fractures. We describe three cases of young children who were presented to the emergency department because of a suspected femur fracture. Although in all cases, the fracture had a similar location and appearance, the clinical history and developmental stage of the child led to three different conclusions. In the first two cases, an accidental mechanism was a plausible conclusion, although in the second case, neglect of parental supervision was the cause for concern. In the third case, a non-accidental injury was diagnosed and appropriate legal prosecution followed. Any doctor treating children should always be aware of the possibility of child abuse and neglect in children with injuries, especially in young and non-mobile children presenting with an unknown trauma mechanism. If a suspicion of child abuse or neglect arises, a thorough diagnostic work-up should be performed, including a full skeletal survey according to the guidelines of the Royal College of Radiologists and the Royal College of Paediatrics and Child Health. In order to make a good assessment, the radiologist reviewing the skeletal survey needs access to all relevant clinical and social information. PMID:26642309

  14. Accidental Symmetries and N=1 Duality in Supersymmetric Gauge Theory

    Leigh, Robert G; Leigh, Robert G.; Strassler, Matthew J.

    1996-01-01

    We note that the accidental symmetries which are present in some examples of duality imply the existence of continuously infinite sets of theories with the same infrared behavior. These sets interpolate between theories of different flavors and colors; the change in color and flavor is compensated by interactions (often non-perturbative) induced by operators in the superpotential. As an example we study the behavior of SU(2) gauge theories with 2\

  17. Timing, ``Accidentals'' and Other Artifacts in EPR Experiments

    Thompson, Caroline H.

    1997-01-01

    Subtraction of ``accidentals'' in Einstein-Podolsky-Rosen experiments frequently changes results compatible with local realism into ones that appear to demonstrate non-locality. The validity of the procedure depends on the unproven assumption of the independence of emission events. Other possible sources of bias include enhancement, imperfect synchronisation, over-reliance on rotational invariance, and the well-known detection loophole. Investigation of existing results may be more fruitful t...

  18. Accidental catheterization of epidural venous plexus: tomographic analysis

    Mariano Paiva Souza

    2016-04-01

    Full Text Available ABSTRACT BACKGROUND AND OBJECTIVES: Inadvertent venous catheterizations occur in approximately 9% of lumbar epidural anesthetic procedures with catheter placement and, if not promptly recognized, can result in fatal consequences. The objective of this report is to describe a case of accidental catheterization of epidural venous plexus and its recording by computed tomography with contrast injection through the catheter. CASE REPORT: A female patient in her sixties, physical status II (ASA, underwent conventional cholecystectomy under balanced general anesthesia and an epidural with catheter for postoperative analgesia. During surgery, there was clinical suspicion of accidental catheterization of epidural venous plexus because of blood backflow through the catheter, confirmed by the administration of a test dose through the catheter. After the surgery, a CT scan was obtained after contrast injection through the catheter. Contrast was observed all the way from the skin to the azygos vein, passing through anterior and posterior epidural venous plexuses and intervertebral vein. CONCLUSION: It is possible to identify the actual placement of the epidural catheter, as well as to register an accidental catheterization of the epidural venous plexus, using computed tomography with contrast injection through the epidural catheter.

  19. Accidental dural puncture rates in UK obstetric practice.

    Gleeson, C M; Reynolds, F

    1998-10-01

    Headache following epidural analgesia is a common cause of complaint, but accidental dural puncture rates vary among hospitals and with techniques. We were therefore interested to discover the extent of audit of dural puncture, the dural puncture rates in those UK centres that kept reliable records, and the techniques they used for detecting the epidural space. Consultants in charge of anaesthetic services to all 257 obstetric units in the UK were sent a questionnaire requesting numbers of obstetric epidurals, techniques used to detect the epidural space and the numbers of accidental dural punctures in the years 1991-1995. Replies were received from 191 respondents (74%) of whom 104 were able to provide some information about dural puncture rates. Dural puncture rate was inversely related to the number of epidurals performed; the highest recorded rate was 3.6% in a unit with 1000. Most respondents did not record the loss of resistance technique used but among those who did, the dural puncture rate using mainly saline was 0.69% and using mainly air was 1.11% (P<0.001). Since accurate patient information is crucial for informed consent, audit needs to be improved in many centres. Though the accidental dural puncture rate may be under-reported in this survey, our data are in agreement with other findings that loss of resistance to saline is safer than loss of resistance to air.

  4. Teaching the Quantal Exposition of the Unified Quantum Theory of Mechanics and Thermodynamics

    Michael R. von Spakovsky

    2006-09-01

    Full Text Available

    The author presents his experience in teaching at a graduate level the quantal exposition of a new non-statistically based paradigm of physics and thermodynamics. This paradigm, called the Unified Quantum Theory of Mechanics and Thermodynamics, applies to all systems large or small (including one particle systems either in a state of thermodynamic (i.e. stable equilibrium or not in a state of thermodynamic equilibrium. It uses as its primitives inertial mass, force, and time and introduces the laws of thermodynamics in the most unambiguous and general formulations found in the literature. Starting with a precise definition of system and of state followed by statements and corollaries of the laws of thermodynamics, the thermodynamic formalism is developed without circularity and ambiguity. In this quantal exposition of the new paradigm, a brief review of the formalism of thermodynamics as a general science not limited to stable equilibrium and large (macroscopic systems as well as a very brief summary of the three prevalent formalisms in classical physics are presented followed by a presentation and development of solutions for a number of elementary problems in quantum physics (e.g., a particle in a box, a harmonic oscillator, a rigid rotor, etc.. These solutions and the maximum entropy principle are then used in a constrained optimization to develop the canonical and grand canonical distributions for Fermi-Dirac and Bose-Einstein types of particles, i.e. for fermions and bosons. This is done without the use of analogies between statistical and thermodynamic results and without additional hypotheses such as the ergodic hypothesis of statistical mechanics. These distributions are then employed under various assumptions (i.e. the Boltzmann, constant-potential, point-particle, and continuous eigenvalue-spectrum approximations to derive the corresponding thermodynamic property expressions for perfect, semi-perfect (ideal, and Sommerfeld gases as

  6. An Exposition on the Nonlinear Kinematics of Shells, Including Transverse Shearing Deformations

    Nemeth, Michael P.

    2013-01-01

    An in-depth exposition on the nonlinear deformations of shells with "small" initial geometric imperfections, is presented without the use of tensors. First, the mathematical descriptions of an undeformed-shell reference surface, and its deformed image, are given in general nonorthogonal coordinates. The two-dimensional Green-Lagrange strains of the reference surface derived and simplified for the case of "small" strains. Linearized reference-surface strains, rotations, curvatures, and torsions are then derived and used to obtain the "small" Green-Lagrange strains in terms of linear deformation measures. Next, the geometry of the deformed shell is described mathematically and the "small" three-dimensional Green-Lagrange strains are given. The deformations of the shell and its reference surface are related by introducing a kinematic hypothesis that includes transverse shearing deformations and contains the classical Love-Kirchhoff kinematic hypothesis as a proper, explicit subset. Lastly, summaries of the essential equations are given for general nonorthogonal and orthogonal coordinates, and the basis for further simplification of the equations is discussed.

  8. Histological alterations in liver and testis of Astyanax aff. bimaculatus caused by acute exposition to zinc

    Daiane Cristina Marques dos Santos*

    2015-04-01

    Full Text Available This study investigated the effect of acute exposition to zinc (Zn on histology of the liver and testes of yellow tail lambari (Astyanax aff. bimaculatus. The exposure consisted of six concentrations of Zn (0, 3, 5, 10, 15, and 20 mg/L for 96 hours of exposure. Fragments of liver and testis were routinely processed and embedded in plastic resin based on glycol methacrylate. Fragments of bones, muscles, liver and testis were dehydrated and digested to quantify the absorption levels of Zn in the tissue. Acute exposure to concentrations above 10mg/L has produced structural changes in the liver and gonads. The changes found in the liver were vascular congestion; decrease of cellular volume; displacement of the hepatocyte nucleus; necrosis; disarrangement of cordon structure; leukocyte infiltrate and vacuolization. The changes found in the gonads were ruptured cyst, delayed development of germ cells, pyknotic nucleus, cell cluster, displacement of cyst wall and vacuolization. The histological changes observed were compatible with the increasing concentration of zinc in environment, compromising liver and reproductive functions, because there was an increase in relative frequency of hepatocytes and reduced sperm production

  9. "Focus on glaciers": an exposition of geo-photos to attract interest on a vanishing beauty

    Rossi, Giuliana; Bohm, Gualtiero; Saraò, Angela

    2016-04-01

    Public awareness of the effects of industrial activity on the environment and climate is growing, but the information needs to be disseminated to a larger number of people, of all ages, to be effective. Images can certainly be an optimal tool to communicate the important message of global warming effects and, thanks to the digital techniques, photography is gaining a new popularity. Anybody, owning just a phone or a tablet, has a camera to catch images that can be immediately spread worldwide via web sites, on-line newspapers, social media or blogs to convey messages and emotions. Fine art photography can surely help in attracting interest and in educating people. For this reason, we organize an exposition of artistic pictures; the beauty of the images attracts the eyes of the public, discovering an unknown reality and gives the opportunity to illustrate the dramatic retreat of the Alpine glaciers, and the majesty of the Antarctic landscape, put in danger by the climate changes. The glaciers are the main characters, with the infinite grey-blue shadows due to change in ice density, the spectacular staircases created by the seracs, and the contrast with the embedding rocks. A sub-set of the images will be presented in this context.

    Statement of work for contract 006 {open_quotes}Mathematical simulation of industrial and accidental release formation and transport{close_quotes} implies that the final result of the activity within this task will be VNIIEF developed techniques which will provide for the prediction of the post-accidental environment. Report [1] presents the description of physical models and calculation techniques which were chosen by VNIIEF to accomplish this task. These techniques were analysed for their capabilities, the areas of their application were defined, modifications within contract 006 were described, the results of test and methodical calculations were presented. Moreover, the experimental data were analysed over the source parameters and contamination measurements which can be used in the comparison with the calculation results. Based an these data this report compares the calculation results obtained with VNIIEF calculation techniques with the LANL-presented experimental results.

    Polymers with special properties have been increasingly applied in the development of technological devices. For example, polymeric materials with special electric properties, such as sulfonated poly-(styrene-acrylic acid) - PSAA-S, are of great interest for showing different conductivities depending on the environment where they are applied. The special properties of PSAA are obtained only after sulfonation step in acidic media. The present work aimed to evaluate the effect of time and temperature exposition in the crystallinity degree of PSAA-S, through a statistical experimental factorial planning. The samples of PSAA-S were submitted to FT-IR and DRX tests. The results showed that the temperature and the time of exposition are significant factors in the crystallinity degree of PSAA-S, considering that the crystal lattices created during the polymerization are damaged by the action of time and temperature at which the polymer is exposed.

    Full Text Available FUNDAMENTO: El mejor conocimiento de los determinantes y circunstancias de producción de los accidentes laborales, favorecerá la implantación de medidas correctoras. El objetivo de este trabajo es describir la evolución temporal de los accidentes de trabajo (AT y determinar los factores de riesgo de baja médica en el Hospital Dr. Peset de Valencia. MÉTODOS: Descripción y análisis retrospectivo de los accidentes de trabajo producidos en el Hospital Dr. Peset de Valencia durante los años 1992 a 1995. Se estimó por métodos deterministas la tendencia y estacionalidad de las series (índices estacionales, IE. Se aplicó un modelo de regresión logística para identificar los factores pronósticos de baja médica y determinar su probabilidad de ocurrencia . RESULTADOS: Las tasas más elevadas de AT se produjeron entre los trabajadores de cocina y lavandería (10,00 AT por 100 trabajadores-año. Los AT con baja médica mantienen una tendencia cercana a cero siendo febrero el mes con I.E más elevado (IE=139,8. Los que cursan sin baja médica tienen una tendencia positiva (r²=0,23, p<0,0001, siendo mayo el mes de mayor siniestralidad (IE=134,2. La probabilidad de que el accidente curse con baja médica aumenta significativamente con la edad, cuando se produce por la tarde, si ha tenido lugar en cocina/lavandería, y si se trata de un esguince o tendinitis. CONCLUSIONES: la actuación sobre la siniestralidad en los AT que cursen con IT, debería centrarse sobre los trabajos menos cualificados y en las áreas de cocina y lavandería.

    Full Text Available Mepivacaine is a potent local anaesthetic and used for infiltration and regional anaesthesia in adults and pediatric patients. Intoxications with mepivacaine affect mainly the CNS and the cardiovascular system. We present a case of accidental intravenous mepivacaine application and intoxication of an infant resulting in seizure, broad complex bradyarrhythmia, arterial hypotension and finally cardiac arrest. The patient could be rescued by prolonged resuscitations and a rapid initiation of ECMO and survived without neurological damage. The management strategies of this rare complication including promising other treatment options with lipid emulsions are discussed.

  20. Evaluation and mitigation of accidental releases of radioactivity

    One result of the workshop was, that even in the case of severe accident sequences in modern nuclear power plants (other facilities were not discussed), there will be enough time to take active measures in order to lower the emissions and to diminish the consequences inside and outside of the plant. On the whole, new evidence from Harrisburg show that previously estimated accidental emissions, especially of radiologically relevant nuclides, have been rather conservative and that much lower emissions are possible, if the above measures are considered. Under accident conditions, models to predict radiation exposure must be applied under the event of a short-term release. (orig./DG)

  2. Self-Administered Ethanol Enema Causing Accidental Death

    Thomas Peterson

    2014-01-01

    Full Text Available Excessive ethanol consumption is a leading preventable cause of death in the United States. Much of the harm from ethanol comes from those who engage in excessive or hazardous drinking. Rectal absorption of ethanol bypasses the first pass metabolic effect, allowing for a higher concentration of blood ethanol to occur for a given volume of solution and, consequently, greater potential for central nervous system depression. However, accidental death is extremely rare with rectal administration. This case report describes an individual with klismaphilia whose death resulted from acute ethanol intoxication by rectal absorption of a wine enema.

  5. Clinical perspectives on osteogenesis imperfecta versus non-accidental injury.

    Pereira, Elaine Maria

    2015-12-01

    Although non-accidental injuries (NAI) are more common in cases of unexplained fractures than rare disorders such as osteogenesis imperfecta (OI), ruling out OI and other medical causes of fracture is always indicated. The majority of OI patients can be diagnosed with the help of family history, physical examination, and radiographic findings. In particular, there are a few radiological findings which are seen more commonly in NAI than in OI which may help guide clinician considerations regarding the probability of either of these diagnoses. At the same time, molecular testing still merits careful consideration in cases with unexplained fractures without obvious additional signs of abuse. PMID:26492946

    The sensitivity of the embryo and foetus varies during pregnancy. Recent studies confirm that the principal damage is mental retardation. It is generally admitted that the risk is negligible for a dose < 100 milli-sieverts (mSv). A possible termination of pregnancy will be considered for an exposure > 200 mSv.The objective of this work is to provide precise information on the various risks related to the irradiation for the foetus, according to the age of gestation and delivered dose, and the action to be taken in case of accidental irradiation. The medical use of ionizing radiation in pregnant women can only be considered within the framework of precise information. (author)

    The aim of the present study was to assess the allergic hazard potential of Pt-containing substances emitted from automotive catalytic converters for the population. This was done by determining exposure-effect relationships in subjects occupationally exposed to platinum compounds in a catalytic converter manufacturing company. The company had been deemed suitable because it could be assumed that the extensive technical industrial safety measures implemented there would make for a considerably reduced exposure to platinum compounds compared to, for example, a platinum separating plant. Exposure-effect relationships were determined on the basis of platinum measurements in a catalytic-converter-manufacturing plant and of a record of new sickness cases. [Deutsch] Ziel der Untersuchung war eine Risikoabschaetzung des Allergie-Gefaehrdungspotentials Pt-haltiger Automobilkatalysatoremittate fuer die Bevoelkerung durch Ermittlung der Expositions-Wirkungsbeziehung bei beruflich gegenueber Platinverbindungen Exponierten in einem Katalysatorfertigungsbertrieb. Der gewaehlte Katalysatorbetrieb war deshalb als geeignet betrachtet worden, weil durch weitgehende technische Arbeitsschutzmassnahmen eine wesentlich geringere Exposition gegenueber Platinverbindungen anzunehmen war als zum Beispiel in Platinscheidereien. Die Expositions-Wirkungsbeziehung sollte durch Platinmessungen in einem Katalysator-Betrieb und Erfassung der Haeufigkeit von Neuerkrankungen im Laengsschnitt definiert werden. (orig.)

  11. Apparence et jeu, valeur cultuelle et valeur d’exposition chez Walter Benjamin

    Anne Boissière

    2007-05-01

    Full Text Available À travers le couple valeur cultuelle/valeur d’exposition présent dans son essai sur la reproductibilité technique, Walter Benjamin introduit une conception historique et dialectique de l’apparence. La valeur contemplative que l’esthétique philosophique accorde à la perception esthétique est relativisée au bénéfice d’une conception pratique de la perception, anciennement tangible dans l’activité magique mais possiblement redéployée avec la photographie et le cinéma. Ce texte veut rendre justice à la dimension pratique et politique qui sous-tend la réflexion de Benjamin sur la reproduction technique : la perception auratique est envisagée comme un moment historique indissociablement lié au développement de la technique.By way of the couple cult-value/exhibition-value as present in his essay on artwork and technical reproduction, Walter Benjamin introduces a historical as well as dialectical theory of appearance. The contemplative attitude often identified with aesthetic perception in philosophical aesthetics is thus deconstructed in favour of a practical mode of perception, formely tangible in magical activity but possibly recovered with photography and cinema. The present article proposes to do justice to the practical and political thought that buttresses Benjamin’s reflection on technical reproducibility: auratic perception is envisaged as a historical moment ineluctably linked to the development of technology.

  1. Accidental staggered paracetamol overdose: An interesting case report

    Kanakkande Aabideen

    2011-01-01

    Full Text Available Paracetamol is one of the most commonly used drugs both over the counter and on prescription. Liquid paracetamol is available over the counter all over the world. Most commonly available concentrations are 120 mg/5 ml and 250 mg/5 ml. Many parents and healthcare professionals assume that doses available in different countries are similar. However, 500 mg/5 ml bottle is available in some countries including the United Kingdom. This leaves a potential for accidental overdose with therapeutic intent. We have reviewed the experience of diagnosing and managing an interesting case of paracetamol over dosage caused by several ingestions over 24 hours period (staggered paracetamol over dosage. It highlights the importance of communication between health professionals and parents while managing common medical problems.

  2. Nodular goiter after occupational accidental exposure to radiation

    2012-07-01

    In the present paper we present the consequences of an accidental occupational radiation exposure at a local hospital in Buenos Aires. Control at a local radiology service showed the lack of correct shielding in the X-ray equipment. The physicians and technicians (14 persons) exposed to radiation during 12 months were examined. The survey shows that: a) In 11 out of 14 radiation-exposed patients nodular goiter developed and an additional patient had diffuse goiter which means a goiter incidence of 85.7%; b) In 5 of the nodular goiter patients an increase in the size or the appearance of new nodules was observed along the follow-up period. No cancer was detected by FNA; c) Hypothyroidism was observed in 3/14 patients, and an additional patient had an abnormal TRH-TSH test, suggesting subclinical hypothyroidism; and d) Increased circulating antithyroid antibodies were found in one of the hypothyroid patients

  3. Siquieros accidental painting technique: a fluid mechanics point of view

    Zetina, Sandra

    2012-01-01

    This is an entry for the Gallery of Fluid Motion of the 65th Annual Meeting of the APS-DFD (fluid dynamics video). This video shows an analysis of the 'accidental painting' technique developed by D.A. Siqueiros, a famous Mexican muralist. We reproduced the technique that he used: pouring layers of paint of different colors on top of each other. We found that the layers mix, creating aesthetically pleasing patterns, as a result of a Rayleigh-Taylor instability. Due to the pigments used to give paints their color, they can have different densities. When poured on top of each other, if the top layer is denser than the lower one, the viscous gravity current undergoes unstable as it spread radially. We photograph the process and produced slowed-down video to visualize the process.

  4. Dose assessment of an accidental exposure at the IPNS

    Seven different methods were used to estimate the dose rate to a female worker who was accidentally exposed in the neutron PHOENIX beamline at the IPNS. Theoretical and measured entrance dose ranged from 550 mrem/min to 2850 mrem/min. Theoretical estimates were based on a Monte Carlo simulation of a spectrum provided by IPNS (Crawford Spectrum). Dose measurements were made with TLDs on phantoms and with ionization chambers in a water phantom. Estimates of the whole body total effective dose equivalent (TEDE) rate ranged from 5.2 mrem/min to 840 mrem/min. Assumed and measured quality factors ranged from 2.6 to 11.8. Cytogenetic analyses of blood samples detected no positive exposure. The recommended TEDE rate was 158 mrem/min. The TEDE was 750 mrem

  5. Accidental intrathecal injection of magnesium sulfate for cesarean section

    Mehryar Taghavi Gilani

    2014-01-01

    Full Text Available Magnesium sulfate is used frequently in the operation room and risks of wrong injection should be considered. A woman with history of pseudocholinesterase enzyme deficiency in the previous surgery was referred for cesarean operation. Magnesium sulfate of 700 mg (3.5 ml of 20% solution was accidentally administered in the subarachnoid space. First, the patient had warm sensation and cutaneous anesthesia, but due to deep tissue pain, general anesthesia was induced by thiopental and atracurium. After the surgery, muscle relaxation and lethargy remained. At 8-10 h later, muscle strength improved and train of four (TOF reached over 0.85, and then the endotracheal tube was removed. The patient was evaluated during the hospital stay and on the anesthesia clinic. No neurological symptoms, headache or backache were reported. Due to availability of magnesium sulfate, we should be careful for inadvertent intravenous, spinal and epidural injection; therefore before injection must be double checked.

Owing to its disinfectant and fixative (i.e. for preserving pathologic tissue specimens in histopathology properties, it is widely used in dentistry. Although, the terms formaldehyde and formalin are often confused as being identical, these are different as to the concentrations of the primary component i.e. formaldehyde. In fact, the common fixative available as 10% neutral buffered formalin is actually a 4% solution of formaldehyde (i.e., a 10% solution made from a 37-40% commercially pure formaldehyde solution. This case report describes an unfortunate case of accidental injection instead of local anesthetic, of formalin into the pterygomandibular space in a 35-year old woman during inferior alveolar nerve block for surgical removal of impacted lower right third molar and its successful management by cautious debridement (under both local and general anesthesia and empirical drug therapy (utilizing analgesics and antibiotics.

  8. Interest of stable iodine prophylaxis in accidental situation

    In the case of an accident on a nuclear reactor, radioactive substances could be released in atmosphere. among these substances, the presence of radioactive isotopes of iodine is a constant, that, in the lack of efficient counter measures could lead to an internal contamination, principally by inhalation but also by contaminated food ingestion. The radioactive iodine accumulate in the thyroid, leading to an exposure that at term can induce an increase of a cancer risk for this gland among the most sensitive persons, especially the children. It exists a simple and efficient protection mean: the taking of a tablet of stable iodine. In this article, the interest of the prophylaxis by stable iodine in accidental situation is tackled under the shape of eleven independent questions/answers, allowing a reading in several times but also the research of response elements to a question that the reader could wonder.

  9. Control of radiation sources and general regulations for accidental situations

    In order to prevent accidents caused by application of radiation sources the Tunisian O.N.P.C. established straightforward strategy made up of 3 phases: prevention, planning and intervention. Civil Protection conducts prevention studies of all radiation sources by examining normal application conditions as well as possible accidental situations. It keeps up with scientific, technical and statistical aspects of radiation risks, elaborates specific plans and programs for intervention operations and cooperates with administrative and security services as well as international organisations. The O.N.P.C. established a model intervention plan based on observation (according to preliminary information), evaluation of the situation (according to the head of operation) intervention (specialized units) and post intervention (testing of personnel)

  10. Proposta di utilizzo di metodologie termografiche per il controllo di qualità di componenti meccanici

    Roberto D’Andrea

    2010-04-01

    Full Text Available In base all’esperienza maturata in anni di sperimentazione sull’analisi delle caratteristiche meccaniche dei materiali mediante indagine termografica, nel presente lavoro è proposta una procedura per il controllo di qualità di componenti meccanici in linea di produzione, che è già stata argomento di brevetto. Lo sviluppo di questo lavoro si colloca nell’ambito del progetto FIRB Smart Reflex “Sistemi di produzione intelligenti, flessibili e riconfigurabili”. L’attività svolta dal DIIM riguarda il controllo avanzato dell’affidabilità di componenti meccanici per l’industria automobilistica. Viene proposta, quindi, la realizzazione di una cella di controllo in linea di produzione capace di valutare la presenza di eventuali componenti difettosi attraverso l’analisi termica degli stessi, sollecitati secondo un modello predefinito. L’attività, svolta in questa prima fase in laboratorio, è facilmente trasferibile in linea di produzione, considerando la possibilità di realizzare celle di prova in ambiente controllato, con condizioni praticamente identiche a quelle di laboratorio, eliminando gli effetti di disturbo che possono influenzare la risposta dell’indagine termografica in ambiente non strutturato.

    Full Text Available Este texto pretende apresentar e discutir algumas concepções de leitura da contemporaneidade, aventando a possibilidade de uma desconstrução dos paradigmas hodiernos relacionados ao logocentrismo de grande parte das teorias e das práticas de leitura oficiais. Para tanto, utiliza-se de uma perspectiva derridiana, levando em consideração as propostas de suplementação e de iteração. Inicialmente, descreve-se um campo teórico para a leitura, partindo de teorias sociais, psicológicas e contextuais, contrapostas, de modo geral, na forma de teorias modernas e teorias pós-modernas de leitura. Depois disso, apresenta-se a proposta de leitura de Jacques Derrida, pautada na problematização da pragmática de Austin e, a partir daí, numa negação da possibilidade de saturação dos contextos de leitura. Finalmente, estabelece-se a necessidade de se repensar os conceitos de leitura vigentes, segundo uma suspensão dos modelos contextuais oficiais, a fim de se discutir as relações de poder implicadas na logofobia que percorre os debates na área.

  17. Performance test of a portable TLD system for accidental doses

    Full text: A portable TLD measuring system was constructed at the J. Stefan Institute many years ago, motivated by the thread of a catastrophic nuclear event. It was designed for fast measurements in accidental dosimetry mainly for military and civil protection use. The system consists of a robust portable measuring unit built for measurements in field conditions, sized about 40 cm in diameter and weighting 5 kg. Dosimeters are based on CaF2:Mn ceramic tablets closed in water resistant plastic housings. In original design producer assured measuring range from cGy to kGy. Specially designed energy compensating filters are used to satisfy requirements for energy response from 0,1 to 3 MeV. Stability of readings is maintained with the temperature stabilized light source. Measuring time for manually driven heating-reading cycle of one dosimeter is about 30 sec. Many systems of the type with sets of dosimeters were stored unused for some years in depositories of different institutions. Modernization of equipment in last years raised questions of applicability of such measurement systems for contemporary needs. The system was thus tested in a secondary standards dosimetry laboratory for compliance with up to date requirements for accidental individual monitoring. Dosimeter characteristics as repeatability, linearity and directional response were of particular interest. As a result of the tests, technical improvements are suggested to extent systems measuring capabilities in order to meet new standards. Possibilities of its use in different fields of dosimetry are discussed, where quick in field measurements of high doses is required as for example in medicine or in civil protection motivated by the new threads of terrorist attacks.

  18. Accidental contamination with 90Sr: a case study

    A case of accidental inhalation and extensive contamination by 90Sr was observed in November 1995 in two workers who were handling a defective waste container with an old source of 90Sr used for lightning rods. An internal monitoring programme was established to obtain experimental excretion data from each worker. Urine bioassays were carried out and activities of 90Sr were determined from analyses of excreta by the liquid scintillation technique. The results were evaluated in accordance with ICRP recommendations using the dosimetric code GENMOD-PC. Since no information was available concerning aerosol size nor compound of the radionuclide, estimations of intakes were made following ICRP 30 recommendations, and an AMAD of 1 μm was assumed for the inhaled radioactive aerosol supposedly containing strontium titanate. The ICRP 30 theoretical excretion curve did not agree with the experimental data. Confirming that the source contained SrTiO3, the assumed 1 μm particle size of the aerosol accidentally inhaled had to be changed to 10 μm, in order to adjust the urinary excretion function to the measured values. The initial estimation for one of the exposed workers, assuming a 1 μm particle size, resulted in a 90Sr intake of 5 ALIs. The final intake estimations were made with the following assumptions: acute inhalation 24 November 1995, AMAD = 10 μm, Class Y solubility and ICRP 30 Respiratory Tract Model for Standard Man. The 90Sr estimated intake was 2.6 x 105 Bq (37% ALI) for one of the workers and 6.6 x 104 Bq (10% ALI) for the other. The committed whole-body effective dose equivalents were 19 mSv and 5 mSv respectively, and the dose equivalents to lung were 147 mSv and 37 mSv, respectively. (author)

  19. Management options in the food chain for accidental radionuclide deposition

    Finland with four other countries participated in the European Union's network project FARMING in 2000 - 2004. The aim of the project was to invite participants from each country representing the food supply chain in a stakeholder group and advance with the groups the networking in building preparedness for accidental contamination of the food production systems. The task of the groups was to evaluate the practicability of management options suggested for reduction of radiation exposure through foodstuffs, and for disposal of waste generated in implementation of these options. The criteria for practicability were effectiveness in reduction of radiation exposure through foodstuffs, technical feasibility, capacity, costs for implementation, secondary costs for waste disposal, socio-economic impact, and acceptability concerning ecology and protection of environment and landscape. Practicable management options aimed at sustainable restoration of food production systems after accidental contamination. The Finnish stakeholder group represented farm production, processing industry, food marketing, catering, advisor organisations for households and agriculture, consumers, nature conservation, the media, experts on environmental impact and authorities responsible for production, safety and security of foodstuffs, food supply and feedstuffs. The group was expected to examine the effect of the Finnish, and, also more generally, northern production conditions on the practicability of the suggested management options. The stakeholder group members first familiarized themselves with intervention after accidental contamination of a large milk production area and thereafter with practicability of individual management options. The evaluation was based on the group members' complementary expertise that very well covered the chain 'from field to fork' whether the issue was related to legislation, production methods, logistics, environmental impacts, or the issues of consumers and

  20. Characterization and Comparison of Injuries Caused by Accidental and Non-accidental Blunt Force Trauma in Dogs and Cats.

    Intarapanich, Nida P; McCobb, Emily C; Reisman, Robert W; Rozanski, Elizabeth A; Intarapanich, Pichai P

    2016-07-01

    Motor vehicle accidents (MVA) are often difficult to distinguish from non-accidental injury (NAI). This retrospective case-control study compared animals with known MVA trauma against those with known NAI. Medical records of 426 dogs and cats treated after MVA and 50 after NAI were evaluated. Injuries significantly associated with MVA were pelvic fractures, pneumothorax, pulmonary contusion, abrasions, and degloving wounds. Injuries associated with NAI were fractures of the skull, teeth, vertebrae, and ribs, scleral hemorrhage, damage to claws, and evidence of older fractures. Odds ratios are reported for these injuries. MVA rib fractures were found to occur in clusters on one side of the body, with cranial ribs more likely to fracture, while NAI rib fractures were found to occur bilaterally with no cranial-caudal pattern. Establishing evidence-based patterns of injury may help clinicians differentiate causes of trauma and may aid in the documentation and prosecution of animal abuse. PMID:27364279

    Full Text Available Este artigo propõe um estudo do texto da proposta curricular do Estado de Minas Gerais, verificando aspectos da relação instaurada entre a instância de produção da proposta – a Secretaria de Educação – e a instância de destinação dessa proposta – o professor de português da rede estadual de ensino. Centrando a atenção no emprego dos conectores, a análise realizada adota os pressupostos teóricos do Modelo de Análise Modular do Discurso, para investigar em que medida esse emprego é decorrente da maneira como a Secretaria de Educação “imagina” o professor ao qual se dirige. O que se constatou foi um predomínio dos conectores que marcam a relação genérica de argumento. Na proposta curricular, esses conectores são empregados com a função de direcionar a leitura do professor, explicitando que as informações por eles introduzidas são argumentos, justificativas, explicações ou exemplos, cujo papel é o de convencer esse professor de que novas concepções de língua e de linguagem devem guiar a sua prática em sala de aula.

  7. Redesenhando o Mapa Eleitoral do Brasil: uma proposta de reforma política incremental

    Octavio Amorim Neto

    2011-06-01

    Full Text Available Este artigo oferece uma proposta de reforma incremental do sistema eleitoral da Câmara dos Deputados. A natureza incremental da proposta se funda na suposição segundo a qual o sistema político é uma arquitetura complexa e delicada, sendo a possibilidade de piorá-lo com mudanças ambiciosas e intempestivas bem maior do que a de aperfeiçoá-lo. A proposta mantém o sistema de representação proporcional com lista aberta, mas altera duas variáveis-chave, uma vez que reduz a magnitude média das circunscrições eleitorais e estabelece uma regra proporcional de distribuição de cadeiras entre partidos coligados. A operacionalização da reforma leva a um novo desenho do mapa eleitoral do país, com circunscrições eleitorais menores dentro de 12 estados. O artigo também apresenta os resultados de um exercício de simulação feito com base nos dados das eleições de 2006 que recalcula a composição partidária da Câmara dos Deputados a partir das regras aqui preconizadas.This article presents a proposal for an incremental reform of the electoral system of the Chamber of Deputies. The incremental nature of the proposal rests on the assumption that this political system is a complex and delicate architecture, and therefore, abrupt and ambitious changes are more likely to make it worse than to improve it. The proposal advocated here maintains the current system of open-list proportional representation, but it changes two key variables of this electoral system, since it reduces its average district magnitude and establishes a proportional distribution of seats among parties that form electoral coalitions. The way the reform is operationalized leads to a redesign of the electoral map of the country, with smaller districts within 12 states. The article also presents the results of a simulation exercise based on data from the 2006 elections, whereby the party makeup of the Chamber of Deputies is recalculated according to the rules proposed

One of the most efficient means at the disposal of any firm, to improve the morale of the individual employees, and to establish a spirit of cooperation between the individual and the firm, is to set up a program of accident benefit. It will avoid direct and indirect losses due to working accidents, as analyzed in a previous article, and it will make it possible to improve total performance of each worker, since he will work in a more favorable environment, free from worry about potential danger to his person. It is almost impossible to describe in detail all those items that should be taken into account in a safety program. None the less, and as an indication of their diversity, some sources of danger are mentioned in this chapter, which are closely connected with human safety, such as public curiosity, travelling from one place to another, cleanliness and order.Todas las personas prefieren desempeñar sus tareas en aquellas organizaciones que tienen hacia ellos las consideraciones correspondientes a un ser humano. Uno de los medios más eficaces a disposición de cualquier empresa para elevar la moral del individuo y para crear un lazo de cooperación común entre el individuo y la empresa, es la de llevar a cabo un programa de prevención de accidentes, programa que redundará en el doble fruto: evitar las pérdidas directas e indirectas causadas por los accidentes de trabajo que se detallaron en un trabajo anterior, y conseguir aumentar el rendimiento del operario al hacerle un ambiente más grato por la preocupación que se demuestra hacia su persona.

    2004-10-01

    Full Text Available Abstract Background Accidental poisoning is one of the leading causes of injury in the United States, second only to motor vehicle accidents. According to the Centers for Disease Control and Prevention, the rates of accidental poisoning mortality have been increasing in the past fourteen years nationally. In Texas, mortality rates from accidental poisoning have mirrored national trends, increasing linearly from 1981 to 2001. The purpose of this study was to determine if there are spatiotemporal clusters of accidental poisoning mortality among Texas counties, and if so, whether there are variations in clustering and risk according to gender and race/ethnicity. The Spatial Scan Statistic in combination with GIS software was used to identify potential clusters between 1980 and 2001 among Texas counties, and Poisson regression was used to evaluate risk differences. Results Several significant (p Conclusion The findings of the present study provide evidence for the existence of accidental poisoning mortality clusters in Texas, demonstrate the persistence of these clusters into the present decade, and show the spatiotemporal variations in risk and clustering of accidental poisoning deaths by gender and race/ethnicity. By quantifying disparities in accidental poisoning mortality by place, time and person, this study demonstrates the utility of the spatial scan statistic combined with GIS and regression methods in identifying priority areas for public health planning and resource allocation.

  14. Suporte à aprendizagem informal no trabalho: uma proposta de articulação conceitual.

    Francisco Antonio Coelho Junior

    2011-12-01

    Full Text Available Quando se analisou o estado da arte em comportamento organizacional, verificou-se a falta de distinção entre os tipos de ação esperados nas distintas etapas do ato de apoiar a ocorrência da aprendizagem, além da necessidade de uma proposição teórica sistemática sobre o suporte à aprendizagem informal em suas diferentes fases. O presente artigo objetiva propor um modelo teórico baseado no ordenamento das etapas de suporte psicossocial à aprendizagem informal, segundo as características e as qualidades das distintas etapas do conceito de aprendizagem informal do trabalho. Com ênfase teórica para a aprendizagem social, a teoria cognitiva social e a hierarquia das formas de aprender, este trabalho enfatiza a importância do suporte psicossocial, com base na teoria da reciprocidade nas relações sociais. Com base em extensa revisão de literatura, propõe-se uma classificação do conceito de suporte, considerando as fases distintas pelas quais o conceito de aprendizagem ocorre, desde a aquisição pelo indivíduo até sua aplicação no trabalho. O suporte à aprendizagem é discutido considerando as etapas processuais de aquisição, retenção, manutenção, generalização e transferência de conhecimentos, habilidades e competências que devem ser expressos nas rotinas de trabalho, ou seja, expressos em desempenho tangível e observável. Assim, torna-se relevante investigar, com base nas etapas do conceito de aprendizagem, qual o tipo específico de ação de suporte que melhor aumentará as possibilidades de ocorrência da ação de aprendizagem e sua transferência para o trabalho. Na literatura, há maior ênfase no estudo da aprendizagem formal, por meio dos programas de treinamento, desenvolvimento e educação. Pouca ênfase é dada ao estudo da aprendizagem informal. A principal limitação deste trabalho é o fato de a classificação do conceito de suporte à aprendizagem proposta ainda não ter sido testada

    PARIS (Post-accidental Radiological Imitation System) is a software developed by the Russian Radiological Protection Institute (IBRAE) at the request of IPSN (French Nuclear Protection and Safety Institute). Its objective is the modelling of post-accidental situations. The PARIS code allows one, in fact, to generate post-accidental scenarios, by simulating the different data flows, notably measurement results, such as they could reach the experts in a real-life situation. The PARIS software is presented, covering its principles, architecture, functions, specifications and application examples. (R.P.)

    Matahri, N. [Institut de Radioprotection et de Surete Nucleaire (IRSN), 92 - Fontenay-aux-Roses (France)

    2006-07-01

    RECUPERARE method has been developed for operating feedback analysis and built on the French Human Reliability Analysis (HRA) principles. It is used to study the causes of human errors or technical failures occurred in French PWRs and the recovery process of events. Based on an event classification (6 categories) model according to the nature of the link between failure and recovery, the identified and recorded data are: the causes of the defects (technical, human, organizational) and the context in which they appear; the factors of the recovery performance (depending on technical and organizational aspects); a chronological analysis, designed to collect delays between failures and their detection/recovery for each event. About 3600 events reported in French PWRs (1997-2003) had been reviewed through this model. Initially, the weight of factors and the most important factors, which influenced the detection and recovery delay, are defined. For this purpose, the regression Partial Least Square (PLS) is used. Then, to link RECUPERARE results with pre-accidental data, conditional probabilities of events linked between them by a cause and effect relationship are calculated.

    Biomarkers,such as chromosome aberration and micronuclei assays,prove to be reliable for facilitating clinical diagnosis in radiation accidents.In a radiation accident in India,chromosomal aberration,γ-H2AX,as well as other blood markers,were detected in accidentally exposed victims.This multi-parametric approach aided in confirming that individuals had been exposed by ionizing radiation.However,doses were impossible to estimate because of a 30-day delay in accident awareness.Exposure dose for victims was estimated using a dose-response curve previously established.Dose estimation,blood cell depletion kinetics,and no appearance of prodromal symptoms suggested that doses of exposure were low.Hematologic investigation,sampling time,and chromosome aberration scoring were all proposed according to data from the victims exposed to 60Co.Finally,knowledge regarding chromosome aberration analysis and the importance of international co-operation and assistance should be shared from this accident.

  18. Non-Accidental Flecainide Overdose - A Case Report

    Abdelilah Ghannam

    2014-12-01

    Full Text Available Flecainide acetate is an antiarrhythmic drug used in the treatment of supraventricular arrhythmias. Flecainide causes very rare but often serious intoxications. These intoxications happen either due to a non-accidental overdose or because of a narrow therapeutic index in a patient who suffers from cardiomyopathy or has electrolyte abnormalities. We report an original case of a patient who had taken a high dose of flecainide with the aim of suicide. The patient suffered a cardiogenic shock with complications of lactic metabolic acidosis. Fast diagnosis is essential to reduce the high morbidity and mortality of this intoxication. The treatment plan is symptomatic. It aims at eliminating the poison and compensating cardiac function by treating the shock and the electrolyte imbalances. This allowed us to swiftly regain normal electrical and mechanical cardiac function in our patient. 3 weeks after the psychiatric consultation no sequelae were found. This case highlights that thorough history is essential in order to determine the diagnosis of a drug intoxication since the range of used products is wide. On the other hand, in case of any intoxication, while we apply a specific treatment, a well-managed, systematic, symptomatic treatment is essential to reduce morbidity and mortality.

  19. Environmental behaviour of accidentally released radionuclides in urban environments

    After a nuclear accident several radionuclides may be released and may contribute to the exposure of members of the public. After the passage of the radioactive cloud, doses to members of the public are mainly due to deposited radionuclides on the ground and other environmental surfaces. For the long-term it is already known that exposure is dominated by Cs-137, although Sr isotopes may also have a significant contribution is some specific environments, related to internal exposure pathways. However, in the first year, Ru and I isotopes may significantly contribute to the exposure of members of the public, from both external and internal exposure pathways. The objective of this work was to gather data on the environmental behaviour of Sr, I and Ru isotopes on urban environments and its contributions to the population exposure, aiming the support for decision making processes on countermeasures to protect people after an accidental release. Results on relative relevance of radionuclides and pathways for the exposure for members of the public, as a function of age and time after the release, are discussed. (author)

  20. Kinematics and kinetics of an accidental lateral ankle sprain.

    Kristianslund, Eirik; Bahr, Roald; Krosshaug, Tron

    2011-09-23

    Ankle sprains are common during sporting activities and can have serious consequences. Understanding of injury mechanisms is essential to prevent injuries, but only two previous studies have provided detailed descriptions of the kinematics of lateral ankle sprains and measures of kinetics are missing. In the present study a female handball player accidentally sprained her ankle during sidestep cutting in a motion analysis laboratory. Kinematics and kinetics were calculated from 240 Hz recordings with a full-body marker setup. The injury trial was compared with two previous (non-injury) trials. The injury trial showed a sudden increase in inversion and internal rotation that peaked between 130 and 180 ms after initial contact. We observed an attempted unloading of the foot from 80 ms after initial contact. As the inversion and internal rotation progressed, the loads were likely to exceed injury threshold between 130 and 180 ms. There was a considerable amount of dorsiflexion in the injury trial compared to neutral flexion in the control trials, similar to the previously published kinematical descriptions of lateral ankle sprains. The present study also adds valuable kinetic information that improves understanding of the injury mechanism. PMID:21824618

    Full Text Available Background. 4-Aminopyridine (4-AP is a drug that is used to improve motor fatigue in patients suffering from multiple sclerosis (MS. Medication error can occur, as commercial preparation may not be available in some countries. Case Presentation. A 58-year-old woman with progressive MS presented with status epilepticus. She was receiving 4-AP for more than 3 years. The symptoms started soon after the ingestion of a single pill that was supposed to contain 10 mg 4-AP, but further investigations revealed that each pill had been inadvertently prepared with an 100 mg 4-AP concentration. The patient was admitted to the intensive care unit (ICU for appropriate management (orotracheal intubation, sedation, and antiepileptic drugs. The first electroencephalogram (EEG showed abundant irregular spike-waves on the left central regions. Neurological condition gradually improved from day 7, while the EEG did not reveal any more electrical seizures but was still consistent with toxic encephalopathy. The patient stayed in the ICU until day 13. At discharge from the rehabilitation ward (2.5 months later, the patient had not yet recovered her previous cognitive and functional condition. Conclusion. A single 100 mg 4-AP accidental overdose may cause serious immediate complications, with a slow and incomplete neurological recovery.

  2. Accidental over-exposure from dental X-ray equipment

    A description is given of an unusual dental X-ray procedure which resulted in accidental over-exposure both to the dentist and to several of his patients when a short-circuit was present in newly-installed equipment. The short-circuit by-passed the exposure control and energized the tube for certain orientations of the X-ray tube. The dentist left the patients, who wore protective aprons, to initiate the exposure themselves, using the control button. Although the warning lights were on, the dentist was not present in the room during the exposure, and the over-exposures were only detected when the developed X-ray films were found to be completely blackened. A reconstruction of the procedure enabled estimates to be made of the dose equivalents to the dentist's body and to the skin of the head, the eyes and the gonads of the patients. The dentist had overlooked several of basic principles recommended in the Code of Practice for the Protection of Persons against Ionizing Radiations from Medical and Dental Use (1972). It is pointed out that incidents involving failure of dental equipment (usually the timer mechanism) are not infrequent. (U.K.)

  3. Taking in account of contextual parameters in post accidental radioecology

    The consequences on agricultural or breeding products of a radioactive accidental release are strongly linked to the context in which radioactive deposits occur: for example conditions of deposition in relation with agricultural and feeding schedules. These contextual parameters lead to a variation of results given by models greater than transfer factors uncertainties. For example, cow milk contamination stretches on several decades during the months following deposit as a function of feeding practices. In the same way, if a wheat plant receives the deposit during grain development, harvested grains will have a contamination level 103 to 104 times higher that if deposition occurs before the growing stage. To create a decision support system like the ASTRAL software, the need to realize a modelling of these contextual parameters has been encountered. Moreover, to help experts for evaluations, default informations relative to agricultural and breeding practices for France are given through databases. However, in case of a real accident, it would be important to re-initialize these contextual parameters which change from year to year, in order to obtain more precise assessments. (authors)

  4. Accidental Cutaneous Burns Secondary to Salbutamol Metered Dose Inhaler

    Ashutosh Kale

    2010-01-01

    Full Text Available We report a case of accidental cutaneous burns caused by salbutamol metered dose inhaler. A 9-year-old boy underwent dental extraction at a children's hospital and was incidentally noted to have burn injuries on dorsum of both hands. On questioning, the boy revealed that a few days ago his 14-year-old brother, who is an asthmatic, playfully sprayed his salbutamol metered dose inhaler on the back of both his hands with the inhaler's mouth piece being in direct contact with the patient's skin. On examination, there was a rectangular area of erythema with superficial peeling on the dorsum of both hands, the dimensions of which exactly matched those of the inhaler's mouthpiece. It is possible that the injury could have been a chemical burn from the pharmaceutical/preservative/propellant aerosol or due to the physical effect of severe cooling of the skin or mechanical abrasive effect of the aerosol blasts or a combination of some or all the above mechanisms. This case highlights the importance of informing children and parents of the potentially hazardous consequences of misusing a metered dose inhaler.

    Full Text Available Los estudios realizados en Chile hasta la fecha no permiten detectar de manera significativa el deterioro neuropsicológico causado por el accidente cerebro vascular (ACV y el impacto que éste tiene en el paciente a nivel de su desenvolvimiento diario y familiar. Con base a esto el objetivo de esta investigación fue elaborar un perfil de deterioro neuropsicológico de las diversas funciones cerebrales superiores causado por un ACV, en un grupo de 50 pacientes de la Unidad de Medicina Física del Hospital San José al cuál se le administró un Protocolo de Evaluación Neuropsicológica, comparándose luego con un grupo control de 50 sujetos evaluados con el mismo protocolo. Se encuentra que sobre un 20% de la población con ACV evaluada presenta deterioro en al menos uno de los ítems evaluados, siendo las funciones ejecutivas, la memoria a largo plazo y la memoria a corto plazo las áreas mayoritariamente afectada en la población evaluada.

  6. Pre-accidental situations highlighted by RECUPERARE method and data

    RECUPERARE method has been developed for operating feedback analysis and built on the French Human Reliability Analysis (HRA) principles. It is used to study the causes of human errors or technical failures occurred in French PWRs and the recovery process of events. Based on an event classification (6 categories) model according to the nature of the link between failure and recovery, the identified and recorded data are: the causes of the defects (technical, human, organizational) and the context in which they appear; the factors of the recovery performance (depending on technical and organizational aspects); a chronological analysis, designed to collect delays between failures and their detection/recovery for each event. About 3600 events reported in French PWRs (1997-2003) had been reviewed through this model. Initially, the weight of factors and the most important factors, which influenced the detection and recovery delay, are defined. For this purpose, the regression Partial Least Square (PLS) is used. Then, to link RECUPERARE results with pre-accidental data, conditional probabilities of events linked between them by a cause and effect relationship are calculated. For this, the Bayesian method with the Bayesian network is built with the PLS obtained results and applied. This constitutes a first approach to take into account in HRA the human and organizational factors highlighted by operating feedback. (author)

  8. Deposition on holm oak leaf surfaces of accidentally released radionuclides

    Rauret, G.; Tent, J.; Rigol, A.; Llaurado, R.M. (Analytical Chemistry Department, University of Barcelona, Barcelona (Spain)); Alegre, L.H.; Utrillas, M.J. (Vegetal Biology Department, University of Barcelona, Barcelona (Spain))

    1994-10-14

    The retention of aerosols by canopies of holm oak trees in a typical Mediterranean forest is studied. Firstly, dry deposition is measured both under and outside the canopy during several months. No clear differences are observed either in the amount or in the chemical composition of the particles collected under and outside the canopy. Secondly, the leaf morphology and anatomy as well as the aerosol deposited onto the leaf surfaces are studied by scanning electron microscopy. Cuticle thickness is measured and differences are observed between young and old leaves. The distribution of aerosol particles over leaf surface is also established. Finally, the possible incorporation into leaves of a radioactive aerosol released in an accidental situation is studied, by means of a sequential extraction procedure using water and an organic solvent. From the results it can be deduced that neither the abiotic layer nor the cuticle play any important role in the retention of caesium. The studied radionuclides are mainly found in particulate form, soluble in water, or incorporated into leaves.

  14. Fate of Accidental Symmetries of the Relativistic Hydrogen Atom in a Spherical Cavity

    Al-Hashimi, M H; Wiese, U -J

    2015-01-01

    The non-relativistic hydrogen atom enjoys an accidental $SO(4)$ symmetry, that enlarges the rotational $SO(3)$ symmetry, by extending the angular momentum algebra with the Runge-Lenz vector. In the relativistic hydrogen atom the accidental symmetry is partially lifted. Due to the Johnson-Lippmann operator, which commutes with the Dirac Hamiltonian, some degeneracy remains. When the non-relativistic hydrogen atom is put in a spherical cavity of radius $R$ with perfectly reflecting Robin boundary conditions, characterized by a self-adjoint extension parameter $\\gamma$, in general the accidental $SO(4)$ symmetry is lifted. However, for $R = (l+1)(l+2) a$ (where $a$ is the Bohr radius and $l$ is the orbital angular momentum) some degeneracy remains when $\\gamma = \\infty$ or $\\gamma = \\frac{2}{R}$. In the relativistic case, we consider the most general spherically and parity invariant boundary condition, which is characterized by a self-adjoint extension parameter. In this case, the remnant accidental symmetry is ...

  15. Accidental hanging deaths in children in Konya, Turkey between 1998 and 2007.

    Dogan, Kamil H; Demirci, Serafettin; Erkol, Zerrin; Gulmen, Mete K

    2010-05-01

    In general, hanging cases are the result of suicide, and accidental and homicidal hanging cases are rarely seen. This study retrospectively investigated 4571 death examinations and autopsies that were performed at The Konya Branch of the Forensic Medicine Council (Turkey) between 1998 and 2007; hanging was involved in 201 (6.5%) of the cases. There were a total of 13 accidental hanging cases, where 12 of these involved children. In seven of the cases, the accidental hanging involved a scarf that wraps around swing-like cradles and is intended to prevent infants from falling down. It was concluded that accidental hanging deaths can be reduced by replacing swing-like cradles with cribs that are designed for children, removing ropes in and around the house, and preventing children from reaching and/or playing with rope-like objects.

    2013-05-15

    Purpose: Efficacy of radiation protection tools for the eye lens dose of the radiologist in fluoroscopic interventions. Materials and Methods: A patient phantom was exposed using a fluoroscopic system. Dose measurements were made at the eye location of the radiologist using an ionization chamber. The setting followed typical fluoroscopic interventions. The reduction of scattered radiation by the equipment-mounted shielding (undercouch drapes and overcouch top) was evaluated. The ceiling-suspended lead acrylic glass screen was tested in scattered radiation generated by a slab phantom. The protective properties of different lead glass goggles and lead acrylic visors were evaluated by thermoluminescence measurements on a head phantom in the primary beam. Results: The exposition of the lens of about 110 to 550 {mu}Sv during radiologic interventions is only slightly reduced by the undercouch drapes. Applying the top in addition to the drapes reduces the lens dose by a factor of 2 for PA projections. In 25 LAO the dose is reduced by a factor between 1.2 and 5. The highest doses were measured for AP angulations furthermore the efficacy of the equipment-mounted shielding is minimal. The ceiling-suspended lead screen reduced scatter by a factor of about 30. The lead glass goggles and visors reduced the lens dose up to a factor of 8 to 10. Depending on the specific design, the tested models are less effective especially for radiation from lateral with cranial angulation of the beam. Occasionally the visors even caused an increase of dose. Conclusion: The exposition of the eye lens can be kept below the new occupational limit recommended by the ICRP if the radiation shielding equipment is used consistently. (orig.)

  5. Transformação organizacional: proposta de modelo para empresas públicas

    Maria Ester Menegasso

    2005-01-01

    Full Text Available O presente trabalho focaliza a transformação organizacional sob o prisma da educação continuada corporativa, de um novo estilo de gestão e de uma metodologia para implementação de mudança organizacional. Também se discutem conceitos e teorias de educação continuada e de estilo de gestão, bem como a metodologia proposta. O argumento central defende a premissa de que a transformação organizacional ocorre a partir da integração da educação continuada corporativa com um novo estilo de gestão e que esse processo se implementa por meio de uma metodologia adequada às singularidades desse tipo de mudança. Com o propósito de oferecer sustentação para esse argumento, discute-se uma pesquisa sobre educação continuada realizada em uma empresa pública, bem como as recomendações que ela ensejou para o processo de mudança dessa instituição. Das recomendações, infere-se que o processo de transformação organizacional é sistêmico em sua essência, que há um processo de aprendizagem sobre mudança - que não decorre do treinamento convencional - e que a transformação é permanente. Cada etapa requer, porém, um período de tempo para se incorporar à cultura da organização. Também se conclui que a transformação pode ocorrer por meio de pessoas ou de processos e que a combinação de ambas as formas pode ser uma estratégia necessária para superar a letargia que a organização burocrática impõe às pessoas. O trabalho finaliza com a apresentação de uma proposta para se levar à prática a transformação organizacional, modelo que se estrutura sobre o tripé da educação continuada corporativa, de um novo estilo de gestão e de uma metodologia adequada para a implementação desse tipo singular de mudança.

  6. Análisis de accidentes severos en contenciones nucleares

    Goicolea Ruigómez, José María

    1992-04-01

    Full Text Available Analysis for severe accidents has recently been added to the long list of requisites imposed on nuclear power plants. In this work we study the rationale and justiflcation for this type of analysis. Calculations for the structural response of the containment buildings can be performed on the computer using advanced nonlinear Finite Element codes. A state of the art review of these methods is carried out, proposing a methodology based on analysis by numerical methods with experimental validation. Additionally we present some results obtained by the authors for the analysis of both reinforced concrete and steel containments. The concluding remarks show the validity of the proposed methodology, as well as the evidence of a large security margin in the containments, due mainly to the conservatisms in the design stage.

    El análisis frente a accidentes severos ha venido a añadirse recientemente a la larga lista de requisitos impuestos a las centrales nucleares. En este trabajo se pretende estudiar la problemática y justificación de este tipo de análisis. El cálculo de la respuesta de la contención se puede realizar en el ordenador mediante métodos avanzados de elementos finitos no lineales. Se hace una revisión del estado de la técnica en estos métodos, proponiendo una metodología basada en el análisis mediante modelos numéricos con validación experimental. Se presentan asimismo los resultados de análisis realizados, para contenciones tanto de hormigón armado como metálicas. Las conclusiones del trabajo establecen la validez de la metodología empleada, así como la constatación de un amplio margen de seguridad existente en las contenciones evaluadas, debido a los conservadurismos del proceso de diseño original.

    2013-01-01

    Full Text Available En el presente estudio se estima la mortalidad proporcional por accidentes de trabajo provocados por violencia interpersonal en Brasil, entre 2000 y 2010. Se analizaron los datos del Sistema de Información sobre Mortalidad, basados en los informes estadísti- cos de defunción del Ministerio de Salud de Brasil, los cuales incluyen un campo para el registro de accidentes de trabajo que debe ser completado en toda defunción por causas externas. Se identificaron 1.368.732 casos de defunciones por causas externas, 31.576 (2,3% por accidentes de trabajo y solo 226 (0,02% por accidentes de trabajo con violen- cia interpersonal. Cerca del 80% de los informes estadísticos de defunción no tenían el campo “accidente de trabajo” completado. La mayor cantidad de casos ocurrió entre hom- bres (94,3% de 25-34 años, con nivel de escolaridad medio, ubicados en la región sudeste y noreste, que trabajan principalmente en la producción de bienes y servicios industriales y la actividad agropecuaria. La mayoría de los casos fueron causados por armas de fuego, seguidos por armas blancas, con un aumento relativo de estos últimos en el período estu- diado. Los resultados sugieren un gran subregistro de diagnósticos que reconocen la rela- ción con el trabajo. Se hace necesaria una mejor capacitación en el llenado de los informes estadísticos, así como estudios que cuantifiquen el subregistro de accidentes de trabajo y accidentes de trabajo con violencia interpersonal.

  10. Doctrinal elements for the post-accidental management of a nuclear accident - Final version

    This report examines and defines the objectives, principles and main actions for the post-accidental management of a nuclear accident. It defines the emergency phase and the post-accidental phase, three basic objectives (to protect the population against the hazards of ionizing radiations, to support populations affected by the accident consequences, to restore affected territories), management principles, key issues for post-accidental management. It defines actions to be undertaken: post-accidental zoning, monitoring of deposited radioactivity, early actions for the protection and taking charge of population, information. It addresses the different aspects of post-accidental management planning in a period of transition: reception of population, reduction of population exposure to deposited radioactivity, treatment of public health problems, improvement of the knowledge on the radiological situation of the environment, improvement of the radiological quality of the different environments, dealing with wastes, empowerment of stakeholders through an adequate governance, support and redeployment of economic activity, help and compensation, information. Appendices more deeply discuss actions to be undertaken just after the emergency phase, for the management of the transition period, and for the management of the long-term period

    Introduction The purpose of this study was to examine county and state-level accidental poisoning mortality trends in Pennsylvania from 1979 to 2014. Methods Crude and age-adjusted death rates were formed for age group, race, sex, and county for accidental poisonings (ICD 10 codes X40-X49) from 1979 to 2014 for ages 15+ using the Mortality and Population Data System housed at the University of Pittsburgh. Rate ratios were calculated comparing rates from 1979 to 2014, overall and by sex, age group, and race. Joinpoint regression was used to detect statistically significant changes in trends of age-adjusted mortality rates. Results Rate ratios for accidental poisoning mortality in Pennsylvania increased more than 14-fold from 1979 to 2014. The largest rate ratios were among 35–44 year olds, females, and White adults. The highest accidental poisoning mortality rates were found in the counties of Southwestern Pennsylvania, those surrounding Philadelphia, and those in Northeast Pennsylvania near Scranton. Conclusions The patterns and locations of accidental poisoning mortality by race, sex, and age group provide direction for interventions and policy makers. In particular, this study found the highest rate ratios in PA among females, whites, and the age group 35–44. PMID:26963396

  12. Fate of accidental symmetries of the relativistic hydrogen atom in a spherical cavity

    Al-Hashimi, M. H.; Shalaby, A. M.; Wiese, U.-J.

    2015-11-01

    The non-relativistic hydrogen atom enjoys an accidental SO(4) symmetry, that enlarges the rotational SO(3) symmetry, by extending the angular momentum algebra with the Runge-Lenz vector. In the relativistic hydrogen atom the accidental symmetry is partially lifted. Due to the Johnson-Lippmann operator, which commutes with the Dirac Hamiltonian, some degeneracy remains. When the non-relativistic hydrogen atom is put in a spherical cavity of radius R with perfectly reflecting Robin boundary conditions, characterized by a self-adjoint extension parameter γ, in general the accidental SO(4) symmetry is lifted. However, for R =(l + 1) (l + 2) a (where a is the Bohr radius and l is the orbital angular momentum) some degeneracy remains when γ = ∞ or γ =2/R. In the relativistic case, we consider the most general spherically and parity invariant boundary condition, which is characterized by a self-adjoint extension parameter. In this case, the remnant accidental symmetry is always lifted in a finite volume. We also investigate the accidental symmetry in the context of the Pauli equation, which sheds light on the proper non-relativistic treatment including spin. In that case, again some degeneracy remains for specific values of R and γ.

  13. Accidental Dark Matter: Case in the Scale Invariant Local $B-L$ Model

    Guo, Jun; Ko, P; Orikasa, Yuta

    2015-01-01

    We explore the idea of accidental dark matter (aDM) stability in the scale invariant local $U(1)_{B-L}$ model, which is a theory for neutrino and at the same time radiatively breaks scale invariance via quantum mechanical dynamics in the $U(1)_{B-L}$ sector. A real singlet scalar can be accidental DM with an accidental $Z_2$, by virtue of both extended symmetries. A $U(1)_{B-L}$ charged complex scalar can also be a viable accidental DM due to an accidental (or remanent) $Z_3$. They can reproduce correct relic density via the annihilations through the conventional Higgs portal or dark Higgs portal. The dark Higgs portal scenario is in tension with the LHC bound on $Z_{B-L}$, and only heavy DM of a few TeVs can have correct relic density. In particular, DM may trigger spontaneous breaking of scale Invariance (SISB). The situation is relaxed significantly in the $Z_3$ case due to the effective semi-annihilation mode and then light DM can be accommodated easily. In addition, the $Z_3$ model can accommodate the Ge...

  16. Communicating Architecture Through the Medium of the Exhibition Communiquer l'architecture par le média exposition

    Full Text Available When analysed as a form of media, exhibitions need to be considered from three different perspectives : that of the person producing the message (curator, that of the person receiving it (visitor and that of the exhibitionary apparatus itself (through the various mise-en-scène strategies employed. This article examines two different ways of thinking about the communication of architecture in the exhibitionary setting. In the first example, which is also the more traditional, the use of the term architecture generally refers to the building, and the curator endeavours to communicate through the medium of the exhibition both the material and experiential aspects of the building. Over the past two decades, a different approach has been employed within the exhibition venue: that of conceptualising architecture not only as a building, but also as a project. This newer approach takes into account aspects such as the generative idea, the creative process, and the many different forms of representation of the building under investigation. Exhibitions focusing on the ideas and creative processes underlying architecture have become common in recent curatorship, with the effect that architecture is increasingly presented in exhibitionary settings as a practice rather than as a historical or theoretical field. The author concludes by explaining that, from the perspective of communication theory, both forms of architectural exhibition neglect their audiences, and consequently the full potential of the exhibition as a form of media is seldom reached.Aborder l’exposition comme média implique de considérer le point de vue du producteur (commissaire, celui du récepteur (visiteur et celui de l’exposition (à travers les moyens employés et l’aspect de l’architecture communiqué. Deux manières d’envisager la communication de l’architecture au musée sont abordées. Pour la première, et selon nous la plus ancienne, le terme architecture est pris

  18. Comparison of intracranial computed tomographic (CT) findings in pediatric abusive and accidental head trauma

    Background. Child abuse specialists rely heavily on diagnostic neuroimaging. Objectives. Study objectives were: (1) to compare the frequencies of six specific intracranial CT abnormalities in accidental and non-accidental pediatric head trauma, and (2) to assess interobserver agreement regarding these CT findings. Materials and methods. Three pediatric radiologists blindly and independently reviewed cranial CT scans of pediatric patients who sustained closed head trauma between 1991 and 1994. All patients were less than 4 years of age. Study cases included thirty-nine (50 %) with non-accidental head trauma and thirty-nine (50 %) with accidental head trauma. Each scan was evaluated for the presence or absence of the following six intracranial findings: (1) interhemispheric falx hemorrhage, (2) subdural hemorrhage, (3) large (non-acute) extra-axial fluid, (4) basal ganglia edema, (5) posterior fossa hemorrhage, and (6) frontal-parietal shearing tear(s). Interobserver agreement was calculated as the percentage of total cases in which all reviewers agreed a specific CT finding was present or absent. Diagnosis required independent agreement by all three pediatric radiologists. The frequencies of these six intracranial CT abnormalities were compared between the two study groups by Chi-square analysis and Fisher's exact test. Results. Interobserver agreement between radiologists was greater than 80 % for all lesions evaluated, with the exception of frontal-parietal shearing tear(s). Interhemispheric falx hemorrhage, subdural hemorrhage, large (non-acute) extra-axial fluid, and basal ganglia edema were discovered significantly more frequently in non-accidental trauma (P ≤.05). Conclusion. Although not specific for child abuse, discovery of these intracranial CT abnormalities in young patients should prompt careful evaluation of family and injury circumstances for indicators of non-accidental trauma.

    Complex and large cryogenic distribution systems are integral part of a fusion machine having superconducting magnets, cryopumps, etc. The various equipment of the cryogenic distribution system are interconnected via Cryogenic Transfer Lines (CTLs) to distribute cold helium to end users. During nominal operation of the fusion machine, helium inventory in CTLs could be in order of several tons. The cold helium present in CTLs could be released in surrounding volume due to accidental scenario. The present analysis, aims to estimate lowest temperature in the surrounding volume due to accidental scenario. The paper will describe simulation results and the test plan in a simulated condition.

    Full Text Available Abstract The use of talcum powder is incorrectly part of the traditional care of infants. Its acute aspiration is a very dangerous condition in childhood. Although the use of baby powder has been discouraged from many authors and the reports of its accidental inhalation have been ever more rare, sometimes new cases with several fatalities have been reported. We report on a patient in which accidental inhalation of baby powder induced severe respiratory difficulties. We also point out the benefits of surfactant administration. Surfactant contributed to the rapid improvement of the medical and radiological condition, preventing severe early and late complications and avoiding invasive approaches.

    Orthodontic archwires or fractured appliances that are accidentally swallowed can become lodged in the airway or gastrointestinal tract. Inadvertent ingestion or aspiration of an appliance or archwire piece during orthodontic appliance adjustment is a medical emergency with potentially serious complications, including possible death from asphyxiation. This article reports the accidental ingestion of a piece of orthodontic archwire that became impacted in the larynx; it was subsequently retrieved. Some potential complications are discussed, along with suggested precautions to prevent such mishaps when using fixed appliances. PMID:22858337

    Accidental injection or leakages of various chemical disinfectants used during root canal preparation into adjacent tissues have been shown to have deleterious effects on surrounding tissue. Formocresol (FC) is an effective intracanal disinfectant used in endodontic procedures. However, it is known to have harmful effects into adjacent tissues. The aim of this article is to present an unusual case in which a 28-year-old male patient developed gingival and bone necrosis after the accidental injection of FC instead of local anesthetic solution for tooth extraction and to review cases in the literature where complications have occurred due to the use of FC.

    Petroleum is considered one of the greatest marine water pollutants, but there have been few studies on the impact of oil on biota. The water-soluble fraction (WSF) of a crude oil contains a mixture of polycyclic aromatic hydrocarbons (PAHs), phenols and heterocyclic compounds. Marine 'pejerrey' Odontesthes argentinensis (Teleostei: Atherinopsidae) is a important commercial species in Brazilian southern region and has great potential for mariculture. The aim of this study was to investigate the lethal and sub-lethal effects of the WSF crude oil exposition on the early life stages of O. argentinensis using acute (96 hours) and chronic (21 days) toxicity tests. Water-soluble fraction of heavy crude oil was prepared using a ratio of one part crude oil to nine parts filtered seawater and mixing for 24 h. Newly hatched larvae and 17 days old larvae were used for the tests, respectively. According to the results, median lethal concentration (LC50) was estimated in 55.0% of the WSF and safe level was estimated in 5.5% of WSF. These data can be used as a tool in environmental conservation studies. Heavy crude oil WSF presented total PAHs of 197.83 ng/mL and total BTEX of 106.1 {mu}g/L. (author)

    Cesium seeded sources for surface generated negative hydrogen ions are major components of neutral beam injection systems in future large-scale fusion experiments such as ITER. The stability and delivered current density depend highly on the work function during vacuum and plasma phases of the ion source. One of the most important quantities that affect the source performance is the work function. A modified photocurrent method was developed to measure the temporal behavior of the work function during and after cesium evaporation. The investigation of cesium exposed Mo and MoLa samples under ITER negative hydrogen ion based neutral beam injection relevant surface and plasma conditions showed the influence of impurities which result in a fast degradation when the plasma exposure or the cesium flux onto the sample is stopped. A minimum work function close to that of bulk cesium was obtained under the influence of the plasma exposition, while a significantly higher work function was observed under ITER-like vacuum conditions.

  10. Histological examination of pancreatic parenchymal changes induced by an experimental fractionated local exposition to X-rays

    After exposition to a total dose of 8,000 R delivered with 16 fractions, the pancreatic parenchymal changes in rats were investigated using histological and histochemical techniques. The observations were performed from the first to the 150th day following the last fraction. During the period of acute changes (1st to 15th day), the most part of the acini is morphologically intact, many smaller or greater necrotic foci, however, are to be seen. This is partly due to the enzymes with cytolytic effects, coming from the damaged smaller ducts and from glandular acini. The formation of the other part of the necrobiotic foci originates not only from direct radiation injury, but also from the capillary lesion by radiation. The injury to the wall of greater ducts induces edema, inflammations, dilatation of efferent ductules and stasis, all this leading consequently to an atrophy of the acini associated with the efferent ducts. During the period of chronical changes (50th to 150th day), the number of capillaries diminishes, the necrobiotic foci are multiplied especially in places where no capillaries are visible. This clearly emphasizes the role of the pathological reasons for capillary lesions. The regenerative phenomena occur only to a lesser extent, being confined to the efferent ducts. The extension of the necrotic zones together with the insignificant regeneration leads to a gradual destruction of the tissular substance. It is concluded that the radiosensitivity of the organ can only be determined, if its acute and chronical changes are known. (orig.)

  11. A noninvasive test of exposition to toxicants: quantitative analysis of cytochrome P4501A expression in fish scales.

    Quirós, Laia; Raldúa, Demetrio; Navarro, Anna; Casado, Marta; Barceló, Damià; Piña, Benjamin

    2007-10-01

    Elevated expression of cytochrome P4501A (CYP1A) is an established biomarker for exposition to a wide range of toxicants, particularly for dioxin and structurally similar compounds. Expression of CYP1A usually is analyzed in internal organs, which involves dissection of the specimen. To avoid unnecessary animal killing, we present here an alternative method based on the monitoring of CYP1A expression in fish scales. Using beta-naphthoflavone (BNF; 50 mg/kg body wt, intraperitoneal injection) as inducer in goldfish (Carassius auratus), we monitored levels of CYP1A mRNA both in scales and liver of treated and control specimens. Treatment with BNF resulted in a similar induction of CYP1A gene in both tissues, although scales responded faster (at 8 h after treatment) than liver (between 24 and 48 h). The scale-based test has the unique advantage of allowing sequential testing in the same specimen, which facilitates analysis of the time course of CYP1A induction and allows the study of individual variability. The method implies minimal suffering of the animals, because it only requires removal of a moderate (n = 1-3) number of scales for each time point. This nondestructive, fast, and relatively inexpensive test for toxic exposure therefore is suitable for environmental monitoring and food safety control programs in which specimen preservation is required.

  6. EFFECTS ON THE PERFORMANCE DURING A MATCHING-TO-SAMPLE TASK DUE TO THE TYPE AND ORDER OF EXPOSITION TO THE TRANSFERENCE TESTS

    CAMILO HURTADO-PARRADO

    2007-08-01

    Full Text Available This study evaluated the effects of manipulating the type and order of presentation of transference tests. Twenty eightundergraduate students divided in 4 groups were exposed to a second order matching to sample procedure. Theconditions of exposition were: ascending difficulty/complexity order of the tests, descending order and two randomlyassigned orders. Results are discussed in terms of percentages of effectiveness; additionally, the latency is proposed asan alternative measure sensitive to the level of difficulty of this kind of tasks. Findings showed heterogeneity in thevelocity of acquisition of the conditional discriminations during the training phase, even though the conditions of thetask were equal for all the subjects. The exposition to the ascending and descending order seemed to affect negativelythe effective behavioral adjustment, whereas one of the randomly assigned sequences seemed to be the best condition.The order of exposition to transference tests, in interaction with a history of early acquisition in the training phase,served to understand the findings of this study and to discuss the necessity of a systematical evaluation of the factors implied in the transference tests. It is suggested to assess the validity of different kind of transference tests and theconvenience of some of them to be use in the investigation of the phenomena related to the effective and variablebehavior.

  7. ‘... conceived by the Holy Spirit and born of the Virgin Mary’: The exposition of the Heidelberg Catechism in the light of present-day criticism

    Ignatius W.C. (Natie van Wyk

    2014-02-01

    Full Text Available The article is a contribution to the 450 year celebrations of the Heidelberg Catechism (HC. Sunday 14, Questions and Answers 35 and 36 receive attention. It deals with the two statements of the creed ‘… conceived by the Holy Spirit and born of the Virgin Mary’. The exposition of the HC is compared to the catechisms of Zacharias Ursinus and John Calvin in order to capture something about the historicity of the text. The exposition of the creed is an on-going process. Karl Barth, Eberhard Busch and Jan Milič Lochman are good examples of Reformed theologians who remain faithful to the intention of the HC, but who explain these statements with present-day criticism in mind. The exposition of Peter Berger is valuable because this sceptic argues that the opinion of modern, liberal Protestantism is of no value. The article concludes that the ‘virgin birth’ as such has no great value. It is only one aspect of the Christian gospel. It also does not proof the divinity of Christ. The divinity of Christ is presupposed.

    Full Text Available Roundup is the most extensively used herbicide in world agriculture. In the present study weexamined the influence of Roundup at the concentration of 15 mg L-1on luteinizing hormone (LHsecretion and reproduction of Prussian carp females. Experiment was conducted at the University ofAgriculture, Department of Ichthyobiology and Fisheries in Kraków, Poland from May to October 2010.Control fish were kept in Roundup–free water. Short-term exposition lasted 10 days, and long-termexposition 6 months. At the end of both experiments samples of blood were collected and all fish wereinjected with salmon GnRH analogue (D-Arg6 sGnRH-A, 10 μg kg-1of b.w. and pimozide (dopamineantagonist, 5 mg kg-1of b.w. After injection blood samples were collected at 6, 12 and 24 hours. LHlevels were measured by the ELISA. For histopathological analyses gill samples were stained with H&Emethod. Analysis of LH concentrations did not show any significant differences between LH levels neitherin experimental nor control group at both times of exposition. However the pathological changes in gillsin fish from experimental groups in short and long-term exposition were found.

  11. Clinical study of lesions caused by accidental local exposure to ionizing radiations

    During the last few years the radiopathology service of the Curie Foundation has admitted more than a hundred patients who were followed and treated for irradiation or suspected irradiation after a work accident. Accidents followed by clinical symptoms account for about half the cases examined. Some of these clinical signs were benign whereas others developed very seriously, all possible conditions between these two extremes being represented. This report neglects cases of high total exposure and deals only with those of partial irradiation where local symptoms predominate, usually at the distal extremities of the upper limbs and exceptionally at the root or distal extremity of the lower limbs. Six clinical cases were selected as particularly revealing and are discussed below: accidental exposure of both hands to an iridium-192 source; chronic exposure to X-rays (left hand and right lower half-lip); accidental exposure of the right hand and antero-external face of the right thigh to a iridium-192 source; acute accidental exposure of the left hand to X-rays emitted under 50 kV; accidental exposure of both hands to cobalt-60 radiation; radiolesions of the left lower limb following a critical power excursion (gamma rays and neutrons)

    Kim, B H; Kim, B C; Lee, J

    2016-07-01

    Dental implants are reliable and widely used, but complications such as peri-implantitis occasionally necessitate their removal. Accidents during removal are similar to those that may occur during extraction, including displacement into another structure in the maxillofacial region. We present a rare case of accidental displacement into the submandibular space, which happened during an attempt to remove an implant. PMID:26507676

  17. Changes in Surface Charge Density of Blood Cells in Fatal Accidental Hypothermia.

    Szeremeta, Michał; Petelska, Aneta Dorota; Kotyńska, Joanna; Pepiński, Witold; Naumowicz, Monika; Figaszewski, Zbigniew Artur; Niemcunowicz-Janica, Anna

    2015-12-01

    The objective of this research was to evaluate postmortem changes concerning electric charge of human erythrocytes and thrombocytes in fatal accidental hypothermia. The surface charge density values were determined on the basis of the electrophoretic mobility measurements of the cells conducted at various pH values of electrolyte solution. The surface charge of erythrocyte membranes after fatal accidental hypothermia increased compared to the control group within whole range of experimental pH values. Moreover, a slight shift of the isoelectric point of erythrocyte membranes towards high pH values was observed. The surface charge of thrombocyte membranes in fatal accidental hypothermia decreased at low pH compared to the control group. However, at pH range 4-9, the values increased compared to the control group. The isoelectric point of thrombocyte membranes after fatal accidental hypothermia was slightly shifted towards low pH values compared to the control group. The observed changes are probably connected with the partial destruction and functional changes of the blood cell structure. PMID:26364031

  8. Paris: a software for simulation of post-accidental radioecological situations

    Paris, a software for simulation of post-accidental radioecological situations. The Paris software (Post-Accidental Radiological Imitation System) has for function to generate post-accidental situation, by simulating the different data flows, notably measurements results, such as they could reach the experts in a real-life situation. Situations proposed are particularly realistic because established by analogy with situations observed after the Chernobyl accident. Many functions reveal this realism: the taking into account of measurements capacity, population movements, the consideration of countermeasures capacity of application and their real efficiency... The data bases used are very extensive which allows diversity of information that the experts will have to process in such a situation. The Paris software constitutes a computerized functional synthesis of operational lessons that one can draw from the Chernobyl accident. In this sense, it presents a considerable interest for preparing experts in the management of post-accidental situations. During crisis exercises, data generated by Paris can be considered as a virtual reality. Experts can compare results from calculation tools like ASTRAL, with this virtual reality. (authors)

    ) or LOAEL (low observed adverse effect level). A small hazard/exposure ratio can be attributed to a probability of high risk, whereas a large ratio indicates a small risk of health hazards. The following article discusses the main principles of exposure estimation. (orig.) [German] Die Bewertung von Verbraucherexpositionen umschliesst alle Quellen und Pfade, ueber die Personen im privaten und haeuslichen Umfeld mit Chemikalien in Kontakt kommen. Dabei sind Verbraucher nicht nur diejenigen, die selbst Verbraucherprodukte anwenden, sondern auch alle weiteren Personen, die sekundaer (indirekt) mit dem Produkt Kontakt haben, z.B. Familienangehoerige. Eine Verbraucherexposition kann gemessen oder geschaetzt werden. Beide Verfahren haben Vor- und Nachteile. Waehrend sich Messungen meistens auf individuelle Expositionssituationen beziehen, beschreiben Modelle eher eine verallgemeinerte Expositionssituation (Szenario). Messungen haben daher ihren Platz, wo Quellen von Schadstoffen aufgespuert werden muessen, Modelle eher dort, wo systematisierte Betrachtungen von Risiken durchgefuehrt werden. Zur Expositionsschaetzung gehoeren 3 Abschnitte, erstens die Charakterisierung der Expositionsquelle (z.B. eine Haushaltschemikalie) mit Beschreibung der Anwendungsmodalitaeten (Haeufigkeit, Dauer); zweitens die Beschreibung des zeitlichen Verlaufes der Konzentration des Stoffes im Kontaktmedium, vor allem in der Luft und auf der Haut. Die Exposition wird darueber hinaus durch das Verhalten der exponierten Person selbst bestimmt. Hier ist die Kontaktdauer, auch Zeitbudget genannt, von grosser Bedeutung. Besondere Verhaltensmuster koennen auch fuer bestimmte Populationen von Bedeutung sein. Man nimmt an, dass z.B. im Kindesalter die orale Aufnahme durch das sog. Mouthing (Hand-in-den-Mund-Stecken) eine besondere Rolle spielt. Die Risikocharakterisierung erfolgt durch einen Vergleich der Exposition, ausgedrueckt als Konzentration oder Dosis, mit dem NOAEL (No Observed Adverse Effect Level

  17. UMA PROPOSTA DE SEGMENTAÇÃO DOS CONSUMIDORES NO COMÉRCIO ELETRÔNICO

    CERIBELI, Harrison Bachion

    2014-04-01

    Full Text Available Despite the growth of electronic commerce, consumer behavior in the sector is still a relatively unexplored subject in academic research published in Brazil. In this context, the aim of this study was to present a proposal of consumer segmentation in e-commerce. To achieve the proposed objective, was made a field survey. The study sample consisted of 500 individuals. To collect data, was used a structured questionnaire based on Likert scale. To analyze the data, was performed a Cluster Analysis. Later, it was possible to identify two segments of consumers: Engaged and Simplifiers. Consumers classified as Engaged are more concerned about having a pleasant shopping experience in electronic retailing, valuing different attributes during the purchase process and engaging in information search and word-of-mouth activities after purchase. Moreover, the segment of consumers Simplifiers includes individuals that are motivated to buy on the Internet by low prices and that value sites reputation, simplifying the process of buying decision. To future studies, we recommend that hypotheses developed in this work be statistically tested and discussed. Apesar do crescimento do comércio eletrônico, o comportamento do consumidor no setor ainda é um tema pouco explorado nas pesquisas acadêmicas publicadas no Brasil. Neste contexto, o objetivo geral deste trabalho foi apresentar uma proposta de segmentação dos consumidores no comércio eletrônico. Para atingir o objetivo proposto, foi realizado um levantamento de campo. A amostra do estudo foi composta por 500 indivíduos. Para a coleta de dados, foi utilizado um questionário estruturado com base na escala de Likert. Para analise dos dados, foi efetuada uma Análise de Cluster. Posteriormente, foi possível identificar dois segmentos de consumidores: os Engajados e os Simplificadores. Os consumidores classificados como Engajados estão mais preocupados em ter uma experiência de compra agradável no varejo

    Brucella abortus strain RB51 vaccine, is an attenuated live bacterial vaccine that was licensed conditionally by the Center for Veterinary Biologics, Veterinary Services, Animal and Plant Health Inspection Service, USDA, on 23 February 1996, for vaccination of cattle in the United States. Accidental human inoculations can occur during vaccination of cattle, and previous live Brucella vaccines designed for cattle have been known to cause brucellosis in humans. The Centers for Disease Control and Prevention (CDC) established passive surveillance for accidental inoculation with the RB51 vaccine in the United States to determine if this veterinary vaccine is associated with human disease, to describe the circumstances of accidental inoculation, to evaluate the potential efficacy of post-exposure chemoprophylaxis, and to develop recommendations for post-exposure management following exposure to RB51. Reports were received from 26 individuals. Accidental exposure to RB51 occurred by needle stick injury in 21 people (81%), conjunctival spray exposure in four (15%), and spray exposure of an open wound in one (4%) individual. At least one systemic symptom was reported in 19 (73%) people, including three (12%) who reported persistent local reactions with systemic involvement. One case required surgery, and B. abortus strain RB51 was isolated from the wound of that individual. Seven cases reported no adverse event associated with accidental exposure. Nine cases reported previous exposure to Brucella vaccines, including one case who also reported a previous diagnosis of brucellosis following exposure to S19 vaccine. Accidental needle stick injuries and conjunctival or open wound exposures of humans with the RB51 vaccine are associated with both local and systemic adverse events in the United States that are consistent with brucellosis; however, it remains undetermined if strain RB51 vaccine can cause systemic brucellosis in humans. Early culture attempts on those exposed and

    In the case of accidental release of hazardous gases in the atmosphere, the emergency responders need a reliable and fast tool to assess the possible consequences and apply the optimal countermeasures. A number of models for the prediction and simulation of hazard areas affected by accidental releases of toxic gases are available worldwide. Modelling accidental releases may be required for a variety of reasons: for analyzing different accidental toxic release scenarios ("worst-case scenarios"), for preparing emergency response plans and optimal countermeasures as well as for real-time risk assessment and management (e.g. in the frame of the SEVESO directive). Depending on the demand and the particular purposes, the choice of the appropriate model is up to the authorities. The one year project was funded by the Austrian Science and research liaison Office (ASO, www.aso.zsi.at) as a part of the program: Research Cooperation and Networking between Austria, the public higher education institutions in Kosovo and South Eastern Europe. The project was conducted by the Central Institute for Meteorology and Geodynamics (ZAMG, http://www.zamg.ac.at) in cooperation with the University of Prishtina (Kosovo, www.uni-pr.edu and the National Institute of meteorology and Hydrology (NIHM Bulgaria, www.meteo.bg). One of the main purposes of the project was to provide the both partners with basic knowledge in modelling with accidental release of toxic gases, based on the practical experience of the meteorologists from the ZAMG in the area. This knowledge can be used as scientific response to society driven current or upcoming problems especially in Kosovo. The activities involved know-how transfer on European standards and practice among the project partners, as well as joint efforts to adapt and disseminate the scientific methods and results in Kosovo. Within the project, the partners from Kosovo and Bulgaria were introduced to the atmospheric dispersion model (ALOHA - Areal

  4. Exposition regarding small windmills

    Emphasis is laid on the elucidation of the current situation of small windmills in Denmark by estimating the industry's strengths and weaknesses and evaluating the technical status and user economy relevant to these wind turbines, in addition to their technical and marketing potentials within the next 3-5 years. It is also attempted to survey and forecast their situation within a competitive market which includes marketing and sales potential outside Denmark, often by way of development projects financed by DANIDA (Danish International Development Agency, a department under the Danish Foreign Ministry that takes responsibility for Danish aid to developing countries, often by direct agreement). It is noted that it is difficult to make predictions in the light of currently rapidly changing global political aspects, but it is suggested that sales of smaller Danish windmills within the country could amount to 300-700 wind turbines by the year 2000. Regarding sales abroad, it is concluded that the current number will not increase unless great efforts are made within the export market and the instigation of close cooperation with foreign companies which use an international sales network and have access to local distribution channels.

  8. Analyses of postulated accidental releases of UF6 inside process buildings

    Uranium Hexafluoride is a material used in the various processes which comprise the front end of the nuclear fuel cycle (conversion, enrichment and fuel fabrication). Confinement of UF6 is a very important safety requirement since this material is highly reactive and presents safety hazards to humans. The present paper discusses the safety relevant aspects of accidental releases of UF6 inside process confinement buildings. Postulated accidental scenarios are analyzed and their consequences evaluated. Implant releases rates are estimated using computer code predictions. A time dependent homogeneous compartment model is used to predict concentrations of UF6, hydrogen fluoride and uranyl fluoride inside a confinement building, as well as to evaluate source terms released to the atmosphere. These source terms can be used as input to atmospheric dispersion models to evaluate consequences to the environment. The results can also be used to define adequate protective measures for emergency situations. (author)

  9. Modelling accidental releases of carbon 14 in the environment: application as an excel spreadsheet

    An application as an Excel spreadsheet of the simplified modelling approach of carbon 14 transfer in the environment developed by Tamponnet (2002) is presented. Based on the use of growth models of biological systems (plants, animals, etc.), the one-pool model (organic carbon) that was developed estimates the concentration of carbon 14 within the different compartments of the food chain and in fine the dose to man by ingestion in the case of a chronic or accidental release of carbon 14 in a river or the atmosphere. Data and knowledge have been implemented on Excel using the object-oriented programming language VisualBasic (Microsoft Visual Basic 6.0). The structure of the conceptual model and the Excel sheet are first briefly exposed. A numerical application of the model under a scenario of an accidental release of carbon 14 in the atmosphere is then presented. Simulation results and perspectives are discussed. (author)

    Concern about the quantity of carbon-14 (14C) released for several decades from nuclear facilities has prompted several modelling approaches of 14C behaviour in the environment. The TOCATTA model aims at estimating 14C (and 3H) transfers in terrestrial ecosystems exposed to atmospheric 14C (and 3H) releases from nuclear facilities under normal operating or accidental conditions. The model belongs to the larger framework of the SYMBIOSE modelling and simulation platform that aims at assessing ...

  5. External hazards in the PRA of Olkiluoto 1 and 2 NPP units - Accidental oil spills

    Oil transports in Finnish territorial waters have increased significantly during the last 10 years. The Gulf of Finland is at this moment a very important route of oil being transported from Russia to the Western Europe. Although the number of accidental oil spills is decreasing in amount and in size, there is a growing concern of their effects to nuclear power plants (NPPs). The amounts of oil transported on the Gulf of Bothnia are much smaller than on the Gulf of Finland. However, accidental oil spills have occurred also there, the size and amount of which are smaller, though. Accidental oil spills are often a result of grounding of a ship or collision of two ships, and often occur during harsh weather conditions like storm or dense fog. However, also coastal oil depots may break, the oil of which may spread over wide distances on the sea. The modelling of initiating events resulting from accidental oil spills includes oil spill response actions performed by the regional rescue services, alarming of the oil spill by the emergency response centre to the NPP rescue services and spill response by the NPPs rescue services. It is unclear what the consequences are if drifted oil would enter the coolant water tunnels. The effect of different oil types to the operation of the safety-related service water systems and components are being assessed. In the ultimate case, an oil spill would clog the inlet channels thus failing the ultimate heat sink of the NPP units. The licensee is evaluating what is the optimal way to operate the NPP units in the case that an oil slick is threatening the plant to ensure reactor core cooling and RHR. The continued operation of, and especially the cooling of, at least one auxiliary feedwater pump is critical in the mitigation of the initiating event. Strategies, like reversing the water flow of the cooling water channels or closing of the cooling water channels, are being evaluated. (authors)

    Full Text Available Om Nemichand Baghele1, Mangala Om Baghele21Department of Periodontology, SMBT Dental College and Hospital, Sangamner, Ahmednagar, Maharashtra, India; 2Private General Dental Practice, Mumbai, IndiaBackground: Accidental ingestion of medium-to-large instruments is relatively uncommon during dental treatment but can be potentially dangerous. A case of BiTine ring ingestion is presented with a note on inefficient ring separation forceps.Case description: A 28-year-old male patient accidentally ingested the BiTine ring (2 cm diameter, 0.5 cm outward projections while it was being applied to a distoproximal cavity in tooth # 19. The ring placement forceps were excessively flexible; bending of the beaks towards the ring combined with a poor no-slippage mechanism led to sudden disengagement of the ring and accelerated movement towards the pharynx. We followed the patient with bulk forming agents and radiographs. Fortunately the ring passed out without any complications.Clinical implications: Checking equipment and methods is as important as taking precautions against any preventable medical emergency. It is the responsibility of the clinician to check, verify and then use any instrument/equipment.Keywords: foreign bodies/radiography, foreign bodies/complications, equipment failure, dental instrument, accidental ingestion

  13. Study of TSL and OSL properties of dental ceramics for accidental dosimetry applications

    Interest is increasing in the development of new methodologies for accidental dose assessment, exploiting the luminescence and dosimetric properties of objects and materials which can be usually found directly on exposed subjects and/or in the contaminated area. In this work, several types of ceramics employed for dental prosthetics restoration, including both innovative materials used as sub-frames for the construction of the inner part of dental crowns (core), and conventional porcelains used for the fabrication of the external layer (veneer), were investigated with regard to their thermally and optically stimulated luminescence (TSL and OSL respectively) properties, in view of their potential application in accidental dosimetry. The sensitivity to ionizing radiation proved to strongly depend on the type and brand of ceramic, with minimum detectable dose ranging from few mGy up to several tens of mGy. A linear dose-response was observed for most of the samples. However, the luminescence signals were characterised by a significant fading, which has to be taken into account for a reliable accidental dose assessment after a radiation exposure event.

  14. Humeral fracture in non-ambulant infants - a possible accidental mechanism

    Somers, John M.; Halliday, Katharine E. [Nottingham University Hospitals, Radiology Department, Nottingham (United Kingdom); Chapman, Stephen [Birmingham Children' s Hospital, Birmingham (United Kingdom)

    2014-10-15

    Humeral fracture in a non-ambulant infant younger than 1 year is suspicious for a non-accidental injury unless there is a credible accidental explanation. A previously unrecognised accidental mechanism was described in 1996 whereby a 5-month-old infant was rolled by a 3-year-old sibling from a prone to a supine position. To investigate the widely accepted view that an infant with limited mobility cannot sustain a fracture of the humerus by his or her own actions in the absence of the intervention of an external party. We present seven cases of non-ambulant infants between 4 and 7 months of age in whom an isolated humeral fracture was the only injury present. In each case the caregiver described the fracture occurring when the child rolled over, trapping the dependent arm, without the intervention of another party. There is no proof for this mechanism in the form of an independent witness or video recording. However, we propose that this mechanism is worthy of further consideration as a rare and unusual cause for the injury. Further study is required. (orig.)

    Full Text Available The development of a conceptual design of an industrial-scale transmutation facility (EFIT of several 100 MW thermal power based on accelerator-driven system (ADS is addressed in the frame of the European EUROTRANS Integral Project. In normal operation, the core power of EFIT reactor is removed through steam generators by four secondary loops fed by water. A safety-related decay heat removal (DHR system provided with four independent inherently safe loops is installed in the primary vessel to remove the decay heat by natural convection circulation under accidental conditions which are caused by a loss-of-heat sink (LOHS. In order to confirm the adequacy of the adopted solution for decay heat removal in accidental conditions, some multi-D analyses have been carried out with the SIMMER-III code. The results of the SIMMER-III code have been then used to support the RELAP5 1D representation of the natural circulation flow paths in the reactor vessel. Finally, the thermal-hydraulic RELAP5 code has been employed for the analysis of LOHS accidental scenarios.

  10. Development of management tools for accidental radiological contamination of the French coastal areas - Development of management tools for accidental radiological contamination in the French marine coastal areas

    The Fukushima nuclear accident led to the most important accidental release of artificial radionuclides into the sea. This accident has underlined the importance of being able to adequately reproduce the fate of radioactive releases and to estimate their consequences for the marine environment. For its Crisis Centre, the French Institute for Radioprotection and Nuclear Safety (IRSN) has operational tools, in order to help experts and decision makers in case of any atmospheric accidental release and terrestrial environment contamination. The on-going project aims to develop tools to manage any marine contamination of the French coastal areas. We should be able to evaluate and anticipate the marine post-accidental situation: contaminated areas localization and contamination levels, and possible consequences. Many sites has be considered as potential source terms into the sea: the Coastal Nuclear Power Plants, the La Hague reprocessing Plant, the Brest and Toulon Military Harbours as home-ports of nuclear powered vessels, and different river mouths (Rhone River, Gironde, Loire, Seine) that could be contaminated by upstream accidental release. To achieve this goal, two complementary approaches are developed: Marine sheets and a dedicated modelling tool (STERNE). - Marine sheets aim to summarize marine environment characteristics for the different sites, identify potential stakes for human protection such as aquaculture areas, beaches, or industrial water intakes, and ecological stakes. Whenever possible, a local climatology (main currents depending on meteorological or tide conditions) that could be a support to first environmental measurement strategy is proposed. A list of available local contacts for any operational management is also provided. - The modelling tool, STERNE (Simulation du Transport et du transfert d'Elements Radioactifs dans l'environNEment marin), must predict radionuclide dispersion and contamination of water, marine species and sediments

  12. Accidental overexposures

    The accident frequency seems to increase rapidly, probably because of the industrial source use development. In opposition to that was noted twenty years ago, the accidents don't involve only the industrial firm or hospital wage earners but also public people. Serious accident analysis puts to the fore the defects which made them possible. The accidents due to energy production reactors are very seldom even if Chernobyl or nuclear submarine accidents have exposed about several hundreds workers to doses going beyond one gray. 78 refs. 17 figs. 14 tabs. 3 annexes

  15. Retinal photoreceptor focal disruption secondary to accidental Nd:YAG laser exposure.

    Milani, Paolo; Pierro, Luisa; Pece, Alfredo; Marino, Valerio; Scialdone, Antonio

    2011-10-01

    Retinal injuries caused by accidental laser exposure include retinal or vitreous hemorrhages, macular holes and edema. We describe the imaging of a bilateral macular lesion secondary to accidental Nd:YAG laser exposure. Observational case report. We performed color photography, fluorescein angiography and autofluorescence (AF) with a scanning laser ophthalmoscope, as well as time-domain and spectral-domain optical coherence tomography (OCT). After accidental exposure to a 1064 nm Nd:YAG laser, a patient experienced blurred vision in the left eye (LE) with visual acuity of 20/60. Color, fluorescein angiography and OCT imaging showed a retinal hemorrhage in the foveal area of the left eye and in the inferomacular region of the asymptomatic right eye. Steroid therapy was then administered, and 5 days later there was rapid improvement with progressive re-absorption of the hemorrhages and functional recovery. At 6 month follow-up, visual acuity was 20/20 in both eyes with unremarkable biomicroscopy, except for focal foveal retinal pigment epithelium (RPE) atrophy in the LE. In comparison to previous hemorrhages, OCT could visualize focal disruption of the photoreceptor IS/OS junction in both eyes. Due to different macular pigment distribution and lesion localization, 787 nm near-infrared AF depicted a small hypofluorescent spot in both eyes, whilst at 488 nm AF a black spot became evident in the right eye only. Despite the re-absorption of foveal hemorrhage and the functional recovery, AF and OCT imaging highlighted the persistence of small focal disruptions of the photoreceptor outer segments and RPE.

  16. PWR physics, operation and safety - Management of accidental situations of the reactor system

    This document contains a brief presentation and the table of contents of a book in which the author first presents the main types of accidents which are taken into account in safety demonstration. He presents the risk concerning the three safety barriers, and the various accidents affecting the three safety functions: reactivity control, power evacuation, confinement by the third barrier. Then the author describes approaches to the management of accidents affecting these three safety functions: reactivity insertion accidents due to absorber withdrawal (presentation, absorber cluster extraction transients, primary fluid dilution transient), steam pipe failure accidents or reactivity insertion by primary cooling (presentation, description of a transient of steam-pipe failure, sensitivity study of main parameters), loss-of-coolant accidents (presentation, intermediate breach, the big breach, peculiar case of breaches in stopped status), total loss of support systems such as in Fukushima (loss of electric supplies, of the cold source), loss of steam generator tubes. In the next part, the author addresses the Three Mile Island (TMI) accident and the lessons learned in terms of post-accidental management: presentation of the reactor and description of the accident. The author presents the 'status approach' of the post-accidental management, addresses the core post-fusion situations and their consequences as far as containment is concerned. He finally proposes ways to manage accidental situations for the PWR system. Appendices propose some additional aspects of system thermal-hydraulics, a presentation of safety deterministic and probabilistic approaches, comments on the Chernobyl and Fukushima accidents, comments on human and organizational factors regarding nuclear safety, some specific design aspects of the PWR reactor regarding safety, a presentation of assessment equations and data for the 1300 MWe PWR model

  18. Heat and mass transfers in a concrete wall with composite liner under accidental conditions

    Billard, Y.; Shekarchi, M.; Debicki, G. E-mail: Gerard.debicki@insa-lyon.fr; Granger, L.; Chauvel, D

    2004-03-01

    The aim of this work was to study the behaviour of a concrete wall, covered with a composite liner and exposed to accidental conditions leading to high temperatures and pressures on a face of the material. In the laboratory, two practical levels of accidental situations (beyond design) have been considered. Firstly, the 'SC1' scenario (accidental conditions) consisted of a rise from ambient conditions to a saturation point of 160 deg. C, and a pressure of 0.75 MPa in 12 h, using the maximum increase possible with the apparatus. This rise was then followed by cooling, leading to 0.22 MPa and 120 deg. C in 24 h. These conditions were maintained for several days. Secondly, a 'SC2' scenario (severe accident conditions) consisted of a rise to a saturation point of 173 deg. C and a pressure of 1 MPa, these conditions were maintained for 24 h before cooling. A cylindrical specimen of 1.3 m of thickness was used. Thermocouples, pressure taps and moisture gauges were implemented before concreting. These devices provided local information, and were mostly distributed in the first 0.30 m of the concrete. The concrete composition (high performance concrete) was the same as that used for the construction of the CIVAUX 2 nuclear power station. Typical experimental results for the evolution of temperature, pressure and water content as functions of time are shown for the two test conditions. The concrete attached to the back of the composite dried, and a mass transfer was induced towards colder zones in the centre of the specimen. The liner acted as a heat insulator and the pressure acting on the back of the composite remained lower than that applied on the composite. The residual adhesion of the liner to the concrete was measured. Finally, the overall results allowed the comparison of situations where the wall was lined and unlined, during exposure to SC1 and SC2 conditions.

    The applications of Electron Paramagnetic Resonance (EPR) for radiation dosimetry are briefly reviewed. In particular, EPR-alanine dosimetry and accidental dosimetry using EPR signals from human tooth enamel have been discussed. The alanine dosimetry was found to be useful from low doses such as 1 Gy to high doses such as 100 kGy. The signals from tooth enamel are found to be invaluable in assessing the absorbed dose of people exposed to radiation accidents and also survivors of atomic bomb explosions. New emerging trends using EPR signals from bones exposed to radiation have also been briefly reviewed. (author)

    The advance made in the nuclear security evaluation of the CAREM reactor is presented. It was carried out using the Security Probabilistic Analysis (SPA). The latter takes into account the different phases of identification and solution of initiating events and the qualitative development of event trees. The method of identification of initiating events is the Master Logical Diagram (MLD), whose deductive basis makes it appropriate for a new design like the one described. The qualitative development of the event trees associated to the identified initiating events, allows identification of those accidental sequences which are to have the security systems in the reactor.

  13. A model of neutrino mass and dark matter with an accidental symmetry

    Amine Ahriche

    2015-06-01

    Full Text Available We present a model of radiative neutrino mass that automatically contains an accidental Z2 symmetry and thus provides a stable dark matter candidate. This allows a common framework for the origin of neutrino mass and dark matter without invoking any symmetries beyond those of the Standard Model. The model can be probed by direct-detection experiments and μ→e+γ searches, and predicts a charged scalar that can appear at the TeV scale, within reach of collider experiments.

    Chlorpyrifos is an organophosphorus anticholinesterase insecticide, and organophosphate intoxication can induce symptoms such as miosis, urination, diarrhea, diaphoresis, lacrimation, excitation of central nervous system, salivation, and consciousness disturbance (MUDDLES). Although accidental poisoning of children with drugs and chemicals is a common cause for consciousness disturbance in children, the possibility of deliberate poisoning is rarely considered. We report on a healthy 5-year 6-month-old boy with recurrent organophosphate intoxication. Reports of chlorpyrifos intoxication in children are quite rare. This case report demonstrates decision-making process and how to disclose deliberate chlorpyrifos poisoning of the toddler by the stepmother, another example of Munchausen syndrome by proxy.

  15. Assessment of radiation dose due to the accidental release of radionuclides from a DCLL reactor

    Highlights: ► Accidental release of radionuclides from a Dual-Coolant He/Pb15.7Li breeding blanket is studied. ► Activation analysis with ACAB code determines the main contributors to the environmental consequences of the accident. ► Atmospheric dispersion (in conditions D and F) is assessed with Hotspot code for the relevant radionuclides. ► The actual quantity of each radionuclide produced in 1 kg of LiPb is used in the dispersion model. ► The amount of LiPb releasable fulfilling the dose limit requirements is calculated. -- Abstract: A conceptual design for a DEMO fusion reactor based on a dual coolant He/Pb15.7Li breeding blanket (DCLL) is being developed within the Spanish Breeding Blanket Technology Programme: TECNOFUS. The production of tritium and activation products of LiPb might be a concern from the radiological safety point of view. Thus, in this contribution, an accidental release in atmosphere of radionuclides from LiPb breeder has been studied. Activation calculations have been performed with ACAB code assuming an irradiation scenario of 5 FPY for the maximum neutron fluence rate in the equatorial breeding zone. The results in terms of specific activity, surface gamma dose rate and committed effective dose (CED) due to inhalation at different times have been used to chose the potentially more hazardous radionuclides. Dispersion of the selected radionuclides has been modeled with HOTSPOT code using the Gaussian plume model and two different atmospheric conditions. Offsite dose (for external irradiation and inhalation) due to an accidental release of 1 kg of activated LiPb has been calculated after 5 FPY of irradiation (shutdown) using HOTSPOT atmospheric dispersion in class D weather conditions. According to the results, fulfilling the dose requirement for no evacuation would permit to release up to 40 kg of activated LiPb, without taking into account the possible isotopic purification and detritiation systems. This value can be compared

  18. Accidental hijab pin ingestion in Muslim women: an emerging endoscopic emergency?

    Goh, Jason; Patel, Neeral; Boulton, Ralph

    2014-01-01

    Ingested foreign body is an infrequent indication for emergency endoscopy in the adult gastroenterology practice. We describe the clinical features and endoscopic management of the first four cases of accidental ingestion of hijab pins by Muslim women in our unit, all presenting within a 12-month period. The pins were all successfully retrieved without any complications. In this report, we review published guidelines and the current literature, as well as discussing the approach (conservative vs proactive endoscopic retrieval) and timing of endoscopic treatment. The Muslim community may need to be alerted to the potential health hazard of hijab pins. PMID:24390968

    We present the case of an accidental extubation in a prone-positioned patient with a challenging airway because of Klippel-Feil syndrome and previous cervical spine fusions. The surgical procedure was well underway when this occurred, which added substantially to the difficulties produced by this event. We herein highlight the corrective steps we took in our case. We also recommend the need for a comprehensive preoperative briefing with all operating room personnel together with an action plan for how to prevent this particular scenario. PMID:27301052

  20. A case study of an accidental inhalation of Am-241 from a ruptured source

    Four workers who were involved in the accidental inhalation of americium-241 were monitored over a period of 660 days post-accident. DTPA treatment commenced on day 1 and was sustained up to 100 days. From measurements on the initial respiratory deposition, the chest and lower abdominal regions, faecal and urinal excretions, initial intakes from 7, 8 to 54,4 kBq were estimated. Lung clearance with half-lives of approximately 1,50 and 500 days were identified. No significant bone deposition was measured. Committed effective dose equivalents were estimated from 2 mSv for the four individuals concerned. (author)

  8. Report on international round table conference 'Accidental radiation contamination of food of animal origin'. Vol. I

    The World Association of Veterinary Food Hygienists (WAVFH) held an international round table conference in Stockholm, Sweden, January 26-29, 1987. The topic of the conference was 'Accidental Radiation Contamination of Food of Animal Origin'. The agenda was divided into three major topic areas: 1. Ecological Science; 2. Veterinary Science - Live Animals; and 3. Veterinary Science - Food of Animal Origin. Experts and delegates from member countries presented papers, participated in discussions and workshops and produced a multidisciplinary report covering the topic areas. The recent accidental release of radioactive substances into the environment from the Chernobyl accident, demonstrated the need for veterinary, ecological, physical and medical sciences to be prepared to respond to an incident in order to protect the environment, food chain, other agricultural assets and humans from the adverse effects of radionuclides. Several presentations suggested that even with the best technologies, national and regional commitment, and relatively unrestricted resource levels, nuclear incidents can cross international boundaries and can contaminate the environment to the extent that the integrity of various food and water supplies can be at risk. Speakers and subsequent discussers tended to concentrate on the issues associated with lessening future environmental impacts if similar types of incidents should occur again

  9. A review of works on Chernobyl unit-4 post-accidental diagnostical investigations

    In this report the main dosimetry methods are shortly described. These methods were used at the first stage accident management are illustrated by the basic results. This task demands very complicated equipment and high-educated personal to be solved. It was needed, at the first stage of the accident mitigation, to determine: The destroyed reactor condition and process parameters and the radiation situation around the accidental unit and its dynamism. As a result of dosimetric measurements at the first stage of MA the new perspective methods and designs appeared. These are calculational methods in field of radiation transport, locations and distinction of sources; the experimental methods of remote dosimetry based on collimated dosimeters and gamma-visors; the space-continous dosimetric cord methods, etc. These methods and means have been described in original reports and are not included in this summarizing chapter. Besides, some new ideas and conceptions, the use of dosimetry methods at the first stages of MA gave a series of proposals and notices on traditional dosimetry mean improvement. In the process of prospectorswork technical requirements were arisen on the emergency dosimeter, robottechnique for accidental condition and so on. These work result in significant experience, whose practical usage depend on availability of means and customers and also on nuclear and radiation technology development in the whole. (orig./HP)

  10. Hybrid parallel strategy for the simulation of fast transient accidental situations at reactor scale

    Highlights: • Reference accidental situations for current and future reactors are considered. • They require the modeling of complex fluid–structure systems at full reactor scale. • EPX software computes the non-linear transient solution with explicit time stepping. • Focus on the parallel hybrid solver specific to the proposed coupled equations. - Abstract: This contribution is dedicated to the latest methodological developments implemented in the fast transient dynamics software EUROPLEXUS (EPX) to simulate the mechanical response of fully coupled fluid–structure systems to accidental situations to be considered at reactor scale, among which the Loss of Coolant Accident, the Core Disruptive Accident and the Hydrogen Explosion. Time integration is explicit and the search for reference solutions within the safety framework prevents any simplification and approximations in the coupled algorithm: for instance, all kinematic constraints are dealt with using Lagrange Multipliers, yielding a complex flow chart when non-permanent constraints such as unilateral contact or immersed fluid–structure boundaries are considered. The parallel acceleration of the solution process is then achieved through a hybrid approach, based on a weighted domain decomposition for distributed memory computing and the use of the KAAPI library for self-balanced shared memory processing inside subdomains

  11. IPSN model for the simplified calculation of atmospheric dispersion of accidental releases

    To assess the atmospheric dispersion of accidental releases, the Institut de Protection et de Surete Nucleaire (IPSN) has developed a so called gaussian plume model. It derives from tri-gaussian puffs, characterized by standard deviations parametrized with respect to the transfer time (for only two classes of vertical atmospheric stability). The analytic form of this model makes it possible to take into account the most important phenomena which change the content of the plume during transfer: reflections, radioactive decay, daughter products, dry and wet deposition. Limitations to the use of this plume model are examined. Its field of application is reduced in the case of weak winds, the more so when the release height is great. A limited number of reference meteorological conditions and standard values for dry deposition velocity (iodine and particles) and the washing rate by rain are proposed, and examples of results are given. This model predicts the order of magnitude of the consequences of accidental atmospheric releases over distances from several hundred meters up to several tens of kilometers

  12. Accidental releases of radionuclides: a preliminary study of the consequences of land contamination

    The long term consequences of land contamination from accidental releases of activity from thermal reactors are examined. The radiological consequences are assessed using an analysis of the exposure of individuals and the population to ground deposits of the radionuclides released. The contribution of the different nuclides in the release by their various exposure routes to the irradiation of man are calculated as a function of time after release and the most radiologically important are identified. A preliminary assessment is made of off-site economic and social consequences of accidental releases by estimating the areas of land which would be affected by the introduction of countermeasures to control individual radiation exposure due to external irradiation from ground deposits (relocation of populations), and the intake of radionuclides contained in locally produced foodstuffs (restrictions on food production). The areas where administrative controls would be necessary decline in size with time after the release; estimates are made of this time-dependent behaviour using dynamic environmental transfer models. Finally, the collective doses saved by the introduction of countermeasures are estimated using population and agricultural distribution data for a rural location in the United Kingdom. (author)

    Two patients with polycythemia vera received intravenously an accidental tenfold overdosage of radiophosphorus therapy (60 and 50 mCi 32P, respectively). In both patients, the occurrence of hemorrhagic complications 3 wk after the 32P medication led to detection of the error and referral to our hospital. Upon admission they showed an agranulocytosis, severe thrombocytopenia, and bone marrow aplasia. In both cases, spontaneous recovery of the hematopoiesis was observed from day 40 posttreatment onward. In one patient, a slow but ultimately complete normalization of blood counts and marrow morphology took place, whereas in the other, a mild thrombocytopenia persists. Nearly 5 yr after the accidental overdosage, both patients are clinically well. Symptoms of polycythemia vera have not reappeared up to now. Attempts were made to evaluate the radiation dose absorbed by the bone marrow. In the first patient, the daily 32P excretion was determined from day 22 to day 60, whereas in the other patient a whole body count was performed on day 78 after administration. From these results, an approximate cumulative bone marrow dose of 10 Sv (1000 rem) could be calculated.

  15. Critical experiments simulating accidental water immersion of highly enriched uranium dioxide fuel elements

    The paper focuses on experimental analysis of nuclear criticality safety at accidental water immersion of fuel elements of the Russian TOPAZ-2 space nuclear power system reactor. The structure of water-moderated heterogeneous critical assemblies at the NARCISS facility is described in detail, including sizes, compositions, densities of materials of the main assembly components for various core configurations. Critical parameters of the assemblies measured for varying number of fuel elements, height of fuel material in fuel elements and their arrangement in the water moderator with a uniform or variable spacing are presented. It has been found from the experiments that at accidental water immersion of fuel elements involved, the minimum critical mass equal to approximately 20 kg of uranium dioxide is achieved at 31-37 fuel elements. The paper gives an example of a physical model of the water-moderated heterogeneous critical assembly with a detailed characterization of its main components that can be used for calculations using different neutronic codes, including Monte Carlo ones.

  16. Risk determination method for accidental water basin contamination based on risk source coupling with sensitive targets.

    2016-01-01

    Accidental water basin pollution seriously threatens human health and ecological security, but rapid, effective methods for evaluating this threat are lacking. This paper aims to develop a risk evaluation method for basin accidents by coupling the risk source with sensitive targets to evaluate the zone accident risk levels of basins and prevent the accidental environmental pollution of water. This method incorporates the interplay between risk sources and sensitive targets by evaluating the zone risk levels of water environments from different sources, effectiveness of the risk source control mechanisms, vulnerability of sensitive targets and spatial and temporal relationships between these sources and targets. Using the Three Gorges Reservoir region as an example, a risk system for water basin pollution incidents consisting of a risk indicator quantification system, a risk zoning method and a verification method for the zoning results is developed and implemented. The results were verified in a field investigation, which showed that the risk zoning model provides rapid, effective and reliable zoning results. This research method could serve as a theoretical reference and technological support for evaluating water basin accident risks. Furthermore, the results are useful for evaluating and protecting the aquatic environments in the Three Gorges Reservoir region. PMID:26207430

  17. Allowing the Accidental; the Interplay Between Intentionality and Realism in Photographic Art

    Katrina Mitcheson

    2010-01-01

    Full Text Available We experience photographs both as intentional and as prone to the accidental. The photograph is both capable of being an artwork with its own, constructed world and of drawing our attention to the reality of the objects used in creating it. In this article I employ the insights contained in the concepts of Barthes’ studium and punctum in order to explore how the artist’s intentions and the realism of photography interact aesthetically. I advance the idea that a unique aesthetics of photography can be rooted in the tension between the intentional, culturally coded message of a photograph and the emanation of a reality that escapes intentional control. Our aesthetic experiences of the artist’s intentions and the appearance of the real depend upon and enhance each other. I claim that the photographer can intentionally allow the accidental, leaving room for the audience to encounter a punctum, and that the control manifested in the photographer's work can serve to heighten the experience of the penetration of the studium by the punctum when it occurs.

  18. Chronic or accidental exposure of oysters to norovirus: is there any difference in contamination?

    Ventrone, Iole; Schaeffer, Julien; Ollivier, Joanna; Parnaudeau, Sylvain; Pepe, Tiziana; Le Pendu, Jacques; Le Guyader, Françoise S

    2013-03-01

    Bivalve molluscan shellfish such as oysters may be contaminated by human pathogens. Currently, the primary pathogens associated with shellfish-related outbreaks are noroviruses. This study was conducted to improve understanding of oyster bioaccumulation when oysters were exposed to daily contamination or one accidental contamination event, i.e., different modes of contamination. Oysters were contaminated with two representative strains of norovirus (GI.1 and GII.3) and then analyzed with real-time reverse transcription PCR. Exposure to a repeated virus dose for 9 days (mimicking a growing area subjected to frequent sewage contamination) led to an additive accumulation that was not significantly different from that obtained when the same total dose of virus was added all at once (as may happen after accidental sewage discharge). Similarly, bioaccumulation tests performed with mixed strains revealed additive accumulation of both viruses. Depuration may not be efficient for eliminating viruses; therefore, to prevent contaminated shellfish from being put onto the market, continuous sanitary monitoring must be considered. All climatic events or sewage failures occurring in production areas must be recorded, because repeated low-dose exposure or abrupt events may lead to similar levels of accumulation. This study contributes to an understanding of norovirus accumulation in oysters and provides suggestions for risk management strategies. PMID:23462089

  19. U.S. regulatory requirements for blast effects from accidental explosions

    This paper is limited to accidental explosions external to nuclear power plants. Procedures for deciding if the risk of damage due to an accidental explosion is sufficiently high to warrant detailed study and methods for assessing structural capability when detailed study is needed are described. The dynamic blast load effect may be estimated by a simplified static procedure. The regulatory staff permits use of a dynamic load factor of 2 applied to the overpressure or reflected pressure, as appropriate, and the assumption that structures and structural elements will deform dynamically as though the loads were applied statically. This assumption allows the designer to compute stresses, moments and shears without reference to the distribution of inertial forces within the structure. Blast pressure should be considered to act both inward and outward to account for dynamic stress reversal. Overturning and sliding stability as well as the ability of supporting structures to carry loads transmitted from the directly loaded exterior surfaces must be assessed. A detailed dynamic analysis in which force-time histories and the stiffness and mass properties of the structures are employed is also acceptable. Damping is not important for air blast effects. The regulatory staff requires that blast effects be resisted elastically. This is consistent with regulatory philosophy that global loading situations should not be permitted to cause global damage. Appendix C to ACI-349, 'Code Requirements for Nuclear Safety Related Concrete Structures', in conflict with regulatory requirements, permits a ductility of 3 for blast loadings

  20. Study of the luminescence properties of dental materials for their use in accidental dosimetry

    Full text: The current social and political situation in many world areas and the increasing hostilities between countries and cultures have accentuated the risk of a malicious use of ionising radiations. Terrorist attacks with the intentional disseminations of radioactive materials in urban settlements may involve a large number of persons, and a rapid estimation of the severity of the exposure is required for undertaking suitable protective actions and supporting decision making. Promising methodologies for a prompt dose evaluation, are those exploiting the luminescence and dosimetric properties of objects and materials which can be easily found in the contaminated area. Among these objects, dental materials have the advantage to be on contact with human body and they could therefore represent individual dosimeters in case of accidental exposure to ionising radiation. The interest in the use of dental ceramics for dosimetric purposes dates back to late 1970, however, it is only through the use of high-sensitive experimental techniques and instrumentation today available, that the potentiality of such materials as accidental dosimeters can be exploited. Moreover, innovative materials are being continuously introduced into the market, containing new additives and pigments with peculiar optical properties. In this study, Thermally Stimulated Luminescence (TSL) and Optically Stimulated Luminescence (OSL) techniques are applied to investigate the luminescence and dosimetric properties of several dental materials, including resins, glass and feldspatic ceramics, and also zirconia and alumina based ceramics, being their use widely increased in the recent years in substitution of metal cores.

    The objective of this study consists in evaluating the sensitivity of the first part of the die grass-milk with respect to an accidental radioactive discharge. We want to know if a single uniform deposit would involve a contamination of the grazing grass identical on the scale of the own territory. The study was based on the A.S.T.R.A.L. model, a computer code developed by the I.R.S.N. which makes it possible to evaluate the transfer of the radionuclides in the terrestrial food chain following an accidental atmospheric emission. The way of transfer of A.S.T.R.A.L. on which the study focused is the transfer of the deposit to milk, via the grazing grass ingestion. The sensitivity of this way of transfer relies on several parameters: captation, yield, cows food rates and dates of setting to grass. Methodology thus consisted in regionalizing these parameters. The software S.T.I.C.S. developed by the I.N.R.A. of Avignon was then used. This model proposes a daily follow-up of the leaf area index which has been correlated with captation and with the production of fresh biomass (yield). (authors)

    Full Text Available Here, authors present a review on clinical presentation and management of exposure of phosgene gas after reviewing the literature by searching with keywords phosgene exposure on Google, Cochrane, Embase and PubMed with a background of experience gained from 10 patients who were admitted to our institute after an accidental phosgene exposure in February 2011 nearby a city in India. Phosgene is a highly toxic gas, occupational workers may have accidental exposure. The gas can also be generated inadvertently during fire involving plastics and other chemicals and solvents containing chlorine, which is of concern to emergency responders. Phosgene inhalation may cause initially symptoms of respiratory tract irritation, patients feel fine thereafter, and then die of choking a day later because of build up of fluid in the lungs (delayed onset non-cardiogenic pulmonary edema. Phosgene exposure is associated with significant morbidity and mortality. Patients with a history of exposure should be admitted to the hospital for a minimum of 24 h for observation because of the potential for delayed onset respiratory failure and acute respiratory distress syndrome.

  3. Structural Integrity Assessment of VVER-1000 RPV under Accidental Cool down Transients

    Corrosion, Fatigue and Irradiation embrittlement are the major degradation mechanisms responsible for ageing of RPV (and its internals) of a Pressurized Water Reactor. While corrosion and fatigue can generate cracks, irradiation damage can lead to brittle fracture initiating from these cracks. Ageing in nuclear power plants needs to be managed so as to ensure that design functions remain available throughout the life of the plant. From safety perspective, this implies that ageing degradation of systems, structures and components important to safety remain within acceptable limits. Reactor Pressure Vessel has been identified as the highest priority key component in plant life management for Pressurized Water Reactors. Therefore special attention is required to ensure its structural integrity during its lifetime. In this paper, structural integrity assessment for typical VVER-1000 RPV is carried out under severe accidental cool down transients using the Finite Element Method. Three different accidental scenarios are postulated and safety of the vessel is conservatively assessed under these transients using the Linear Elastic Fracture Mechanics approach. Transient thermo mechanical stress analysis of the core belt region of the RPV is carried out in presence of postulated cracks and stress intensity factors are calculated and compared with the material fracture toughness to assess the structural integrity of the vessel. The paper also include some parametric analyses to justify the methodology. (author)

  4. Accidental pollution in the ocean: besides crude oil, chemicals and other spills

    Accidental pollution of the seas is usually illustrated by the shipwreck of tankers carrying crude oil. We must look beyond this image since such accidents spill substances other than petrochemicals. We need but mention the Levoli Sun's accident near the Cotentin peninsula, France, one year after the Erika went down. And what about spills of agricultural and food products? An accidental spill as apparently harmless as wheat might have serious effects on not just the environment but also human health. In all cases, two major series of questions crop up: 1) Is it necessary to intervene? If so, are we able to? And if we can, how to fight against spills? 2) What are the short- and long-term effects on the environment and on all human activities related to the sea (fishing, fish-farming, salt production, tourism, salt-water cures, etc.)? These two questions have a common denominator: the need to know how spilled products react. This knowledge conditions both the operational response for fighting against pollution and the assessment of the impact on the maritime environment. (author)

  5. Hazards of combustible gases accidentally released from the process plant of HTGR process applications

    This report summarizes the preliminary work on reformer explosions for the indirect cycle plant design effort of the High-Temperature Gas-Cooled Reactor for Process Heat (HTGR-PH). Models were completed for the determination of the combustible behavior of the releases (either instantaneous like puffs or continuous like jets or plumes), the amount of combustible material, and the propagation of detonation and shock waves (i.e., blast) as a consequence of potential explosions. A preliminary analysis reveals that (1) incombustible or flammable but nonexplosive mixtures can be formed by accidental releases from the reformer inlet flow and (2) the addition of sufficient steam to the reformer flow renders nonexplosive any accidental release from the reformer area. The explosion of combustible releases is then analyzed with reference to the worst contributor: synthesis gas. The explosions of instantaneous releases, while enroute, are analyzed under different meteorological conditions. The explosions of continuous releases are analyzed in situ for determining the effects on structures and equipment in the vicinity of the jets by considering (1) detonations inside the combustible region of jets and (2) blasts outside the combustible region of jets

    2006-04-01

    Full Text Available An important phase of endodontic treatment is the irrigation of the root canal system. Desirable functions of irrigation are antimicrobial activity, dissolution of necrotic tissue, and non toxicity to the periradicular tissue. Toxicity of NaOCl solution on vital tissue is still controversial. Severe complications may occur if this solution is inadvertently exposed to the oral mucosa, and it is very hazardous. The purpose of this paper is to caution dentists on the hazards of using NaOCl irrigation in endodontic treatment. A case is presented in which 2.5% NaOCl solution was accidentally streaming into the patient's throat because the irrigating needle was not securely attached to the syringe, with the result that the patient had difficulty in breathing. The patient was promptly taken to a pulmonologist, internist, and ENT. The patient was given dexamethasone 10 mg iv injection, delladryl 1 cc iv, and nebulizer with 1 ampoule of steroid, 1 ampoule of ventolin and 5 cc NaCl 3x within 24 hours, and after 24 hours the condition was increased. From this case it is concluded that the 2.5% NaOCl solution is very alkaline and irritating, resulting in deem of the larynx and plugging up of the respiratory system. Clinicians need to be cautious in using NaOCl solution to avoid endangering the patient's life.

  9. Sulphuric acid marketed in water bottle in India: A cause for fatal accidental poisoning in an adult.

    Behera, C; Chopra, Saurav; Garg, Aayushi; Kumar, Rajesh

    2016-06-01

    Corrosive acid ingestion is a rare but serious health hazard with fatal complications. Cases of suicidal and accidental acid ingestion have been documented in the scientific literature. Accidental acid poisoning due to a mistaken identity of the bottle containing sulphuric acid is a matter of grave concern especially in a household set-up. We hereby report a fatal case of accidental sulphuric acid ingestion in an adult, who unsuspectingly swallowed about 50 ml of 'toilet-cleaner' at his residence. The bottle containing the acid was recently purchased from a local vendor and placed with water bottles in the kitchen. The autopsy and toxicological findings of this case are discussed in this paper with discussion of medico-legal issues on the sale and use of such corrosive acids in illegal bottles and its subsequent health hazards in India.

  13. Larger-area single-mode photonic crystal surface-emitting lasers enabled by an accidental Dirac point

    Chua, Song-Liang; Bravo-Abad, Jorge; Joannopoulos, John D; Soljacic, Marin

    2013-01-01

    By altering the lattice geometry of the photonic crystal surface-emitting lasers (PCSELs), we tune the regular lasing band edges of quadratic dispersions to form a single accidental Dirac point of linear dispersion at the Brillouin zone center. This not only increases the mode spacing by orders of magnitude, but also eliminates the distributed in-plane feedback to enable single-mode PCSELs of substantially larger area thus substantially higher output power. The advantages of using accidental Dirac cones are systematically evaluated through two-dimensional in-plane calculations and confirmed by three-dimensional simulations of photonic crystal slab devices.

  14. Urban "accidental" wetlands mediate water quality and heat exposure for homeless populations in a desert city

    Palta, M.

    2015-12-01

    In urban settings where humans interact in complex ways with ecosystems, there may be hidden or unanticipated benefits (services) or harm (disservices) conferred by the built environment. We examined interactions of a highly vulnerable population, the homeless, with urban waterways and wetlands in the desert city of Phoenix, Arizona, U.S.A. Climate change models project increases in heat, droughts, and extreme floods for the southwestern U.S. These projected changes pose a number of problems for sustainability and quality of future water supply, and the ability of human populations to mitigate heat stress and avoid fatalities. Urban wetlands that are created "accidentally" (by water pooling in abandoned areas of the landscape) have many structural (e.g., soils and hydrology) and functional (e.g., high denitrification) elements that mimic natural, unaltered aquatic systems. Accidental wetland systems in the dry bed of the Salt River, fed by storm and waste water from urban Phoenix, are located within economically depressed sections of the city, and show the potential for pollutant and heat mitigation. We used a mixed-method socio-ecological approach to examine wetland ecosystem functions and the ways in which homeless populations utilize Salt River wetlands for ecosystem services. Interviews and trash surveys indicated that homeless people are accessing and utilizing the wetlands as a source of running water, for sanitary and heat mitigation services, and for recreation and habitation. Environmental monitoring demonstrated that the wetlands can provide a reliable source of running water, nutrient and pathogen removal, heat mitigation, and privacy, but they may also pose a health risk to individuals coming in contact with the water through drinking or bathing. Whether wetlands provided a net benefit vs. harm varied according to site, season, and particular service, and several tradeoffs were identified. For example, heat is highest during the summer storm season

  15. The Chernobyl – Thirty Years After The Post – Accidental Radiological – Hygienic and Medical Consequences

    G. G. Onishchenko

    2016-01-01

    Full Text Available As the result of the Chernobyl NPP accident more than 200 thousand square kilometers of the European territories were contaminated by Cs-137 in the amount of above 37 kBq/m2 (1 Ci/km2 . Belorussia, Russia and Ukraine amount up to 70% of this entire affected area. More than 600 000 people were engaged in the accidental cleanup operations, 340000 were evacuated or relocated within 1986-1991. The early stage evacuation efficacy is confirmed by the absence of acute radiation syndrome among the population and by the prevented collective dose which amounts to no less than 10 000 man/Sv. The effective measure to reduce the internal radiation dose to the population at the early accidental stage was introduction of maximum tentative permissive levels of radionuclide content in the foodstuffs.Among the identified post -accident medical consequences of the Chernobyl is the radiation syndrome found in 134 emergency cleanup workers within the first 24 hours of the accident’s development. Out of that number, 28 people died within the first four months, 19 people died before 2006. The accident’s liquidators developed radiation -induced leukemia ( the attributive risk value is 45-60% . People exposed to high radiation doses display the statistically significant 18% morbidity increase of all types of solid cancers at the doses above 150 mSv. There is the statistically significant information indicating the increased amount of thyroid cancer morbidity among those who were just children and teenagers at the time of the accident. The adverse psychological consequences are accounted for not just the fear of overexposure but also for the disturbance of the habitual lifestyle especially mindful of the forced relocation.The longterm protection measures, radionuclide decay and selfcleaning of the contaminated areas resulted in the drastic reduction of the population dose in the radioactively contaminated territories. In 2015, only in some settlements of the Briansk

  16. Dispersion modeling of accidental releases of toxic gases - Sensitivity study and optimization of the meteorological input

    Baumann-Stanzer, K.; Stenzel, S.

    2009-04-01

    Several air dispersion models are available for prediction and simulation of the hazard areas associated with accidental releases of toxic gases. The most model packages (commercial or free of charge) include a chemical database, an intuitive graphical user interface (GUI) and automated graphical output for effective presentation of results. The models are designed especially for analyzing different accidental toxic release scenarios ("worst-case scenarios"), preparing emergency response plans and optimal countermeasures as well as for real-time risk assessment and management. Uncertainties in the meteorological input together with incorrect estimates of the source play a critical role for the model results. The research project RETOMOD (reference scenarios calculations for toxic gas releases - model systems and their utility for the fire brigade) was conducted by the Central Institute for Meteorology and Geodynamics (ZAMG) in cooperation with the Vienna fire brigade, OMV Refining & Marketing GmbH and Synex Ries & Greßlehner GmbH. RETOMOD was funded by the KIRAS safety research program at the Austrian Ministry of Transport, Innovation and Technology (www.kiras.at). The main tasks of this project were 1. Sensitivity study and optimization of the meteorological input for modeling of the hazard areas (human exposure) during the accidental toxic releases. 2. Comparison of several model packages (based on reference scenarios) in order to estimate the utility for the fire brigades. This presentation gives a short introduction to the project and presents the results of task 1 (meteorological input). The results of task 2 are presented by Stenzel and Baumann-Stanzer in this session. For the aim of this project, the observation-based analysis and forecasting system INCA, developed in the Central Institute for Meteorology and Geodynamics (ZAMG) was used. INCA (Integrated Nowcasting through Comprehensive Analysis) data were calculated with 1 km horizontal resolution and

    2014-10-01

    Full Text Available INTRODUCTION: Acute accidental poisoning in children is a big problem anywhere in the world. Studies done elsewhere in India showed a wide range of incidence of the problem. Hence, it was felt important to study its magnitude and associated characteristics as of now. OBJECTIVE: The current study was taken up to know the magnitude among children admitted in JNIMS, Imphal which is a newly established medical institute and also to study the characteristics like age, gender, type of poison, duration of hospital-stay and outcome of the cases. MATERIALS & METHODS: Retrospective data of all acute accidental poisoning cases among children admitted in the Pediatrics Ward, JNIMS, Imphal during the period July 2008 - December 2013 were analyzed by using descriptive statistics. RESULT: Of all the 13,663 children admitted, 148 cases were because of acute accidental poisoning giving an incidence rate of 1.08%. The male is to female ratio was 1.31:1. The last three years of the study period showed a slightly increasing trend in the incidence. Children aged 1-4 years were the most commonly affected (65.54%. Kerosene oil was by far the commonest (42% of all the poisonous substances consumed. Food poisoning, poisoning with organic compounds, poisoning with medicinal drugs and poisoning with corrosives comprised 21%, 12%, 9% and 8% respectively of all the cases. There was no mortality. DISCUSSION: The incidence rate of 1.08% as found out from the current study was on the lower side as compared to reports of previous studies done in other parts of the country. Yet, it was two-fold of the incidence reported from RIMS which is situated in the same State. Parental negligence in storing poisonous substances in the household was implicated. They need to be made aware for keeping harmful poisonous substances in safe places out of the reach of children. CONCLUSION: Community-based studies are recommended for estimating more accurately the magnitude of the problem in the

  2. Dynamic evaluation of environmental impact due to tritium accidental release from the fusion reactor

    As one of the key safety issues of fusion reactors, tritium environmental impact of fusion accidents has attracted great attention. In this work, the dynamic tritium concentrations in the air and human body were evaluated on the time scale based on accidental release scenarios under the extreme environmental conditions. The radiation dose through various exposure pathways was assessed to find out the potential relationships among them. Based on this work, the limits of HT and HTO release amount for arbitrary accidents were proposed for the fusion reactor according to dose limit of ITER. The dynamic results aim to give practical guidance for establishment of fusion emergency standard and design of fusion tritium system. - Highlights: • Dynamic tritium concentration in the air and human body evaluated on the time scale. • Different intake forms and relevant radiation dose assessed to find out the potential relationships. • HT and HTO release amount limits for arbitrary accidents proposed for the fusion reactor according to dose limit

    We present the acute management and outcome of a patient after an accidental mesenteric distribution of Y90 microspheres during radioembolization (RE). This report describes and highlights: (1) the incidence of a significant reflux during a RE session while injecting into a replaced right hepatic artery from the superior mesenteric artery, (2) the appearance of diffuse mesenteric Y90 distribution in bremsstrahlung-imaging, (3) the management protocol with the radiation protection agent amifostine, (4) the development of typical adverse effects in the expected time window, and (5) survival of the patient without long-term sequelae. This report should sensitize physicians to this particular problem and may help to avoid as well as manage similar radioembolization incidences.

  6. Accidental beam loss in superconducting accelerators: Simulations, consequences of accidents and protective measures

    The consequences of an accidental beam loss in superconducting accelerators and colliders of the next generation range from the mundane to rather dramatic, i.e., from superconducting magnet quench, to overheating of critical components, to a total destruction of some units via explosion. Specific measures are required to minimize and eliminate such events as much as practical. In this paper we study such accidents taking the Superconducting Supercollider complex as an example. Particle tracking, beam loss and energy deposition calculations were done using the realistic machine simulation with the Monte-Carlo codes MARS 12 and STRUCT. Protective measures for minimizing the damaging effects of prefire and misfire of injection and extraction kicker magnets are proposed here

  7. Knowledge management for modelling nuclear power plants control in incidental and accidental states

    A knowledge model uses different techniques of complex systems management. Progress realised in the computer representation of links between different documents allows us to design a software facilitating the comprehension of the model built. This model is a qualitative model of the operators' behaviour in nuclear power plant accidental control. This model concerned three topics closely linked together. The first gives a description of every physical phenomena implied the application of the State-oriented Approach (APE in French) procedures. It's referred as model of process. The second gives a description of every activities used by the operators' team to manage all thermohydraulic incidents and accidents. It's a functional model also referred as tasks model. The quality of the method, based on the Systems' Science, capitalized a know-how simply transferable to design a new software on industrial process to support the operators. (author)

  8. Hybrid parallel strategy for the simulation of fast transient accidental situations at reactor scale

    This contribution is dedicated to the latest methodological developments implemented in the fast transient dynamics software EUROPLEXUS (EPX) to simulate the mechanical response of fully coupled fluid-structure systems to accidental situations to be considered at reactor scale, among which the Loss of Coolant Accident, the Core Disruptive Accident and the Hydrogen Explosion. Time integration is explicit and the search for reference solutions within the safety framework prevents any simplification and approximations in the coupled algorithm: for instance, all kinematic constraints are dealt with using Lagrange Multipliers, yielding a complex flow chart when non-permanent constraints such as unilateral contact or immersed fluid-structure boundaries are considered. The parallel acceleration of the solution process is then achieved through a hybrid approach, based on a weighted domain decomposition for distributed memory computing and the use of the KAAPI library for self-balanced shared memory processing inside sub-domains.

    Glasscock, David John; Rasmussen, Kurt; Carstensen, Ole;

    2006-01-01

    Farming is one of the most hazardous occupations in terms of the incidence and seriousness of accidental injuries. Research with other occupational groups has drawn attention to the role of psychosocial factors and stress. Such research needs to be extended to agriculture. Since stress may be a...... problem faced by farmers, there is a particular need to investigate the associations between farm accidents and work stressors and stress reactions. Using multivariate logistic regression analyses, this study aimed to uncover the best psychosocial predictors of injury, while controlling for exposure......-related confounders. From a randomly selected sample of 794 farms, 10% of all farms in Ringkoebing County, Denmark, 393 farmers completed completed weekly accident registration over 12 months. The study sample consisted of 310 farmers who also completed questionnaires on psychosocial factors. Results indicated that...

  10. Relative public health effects from accidental release of fusion structural radioactivity

    The FUSECRAC code, a modification of the CRAC code, was developed to estimate public health effects from released fusion radioactivity both for safety studies and for comparison of the hazards associated with candidate structural materials. This paper summarizes the key motivations, problems, and results of the FUSECRAC comparison. The evolving CRAC code is a product of the Reactor Safety Study and represents the state of the art in fission accident consequence assessments. It was found that potential public health effects from accidental releases of 316 SS are two orders of magnitude higher than from V-15Cr-5Ti or TZM per unit volume of activated first wall released. The probabilities for releases among these materials were not addressed here

  11. Multiple-Purpose Personal Dosimeter Suitable for Dosimetry of High Accidental Exposures

    The paper describes the personal dosimeter designed by the Commissariat à l'énergie atomique to permit evaluation of the doses received by workers liable to high accidental exposures. It consists of a film dosimeter plus a glass, threshold and activation detector pack. The film dosimeter consists of a case fitted with screens demarcating seven different areas of the film. The latter, which provides density measurements by reflection, consists of three emulsions of different sensitivities on a common base, so that a single development covers the dose range between 20 mr and 800 r. An NTA nuclear-emulsion, fast-neution dosimeter can be added. Two glass dosimeters of different characteristics are included to permit separate evaluation of gamma and thermal neutron radiation. The unit also possesses conventional threshold and activation detectors. (author)

  12. Accidental Continuous Releases from Coal Processing in Semi-Confined Environment

    Bruno Fabiano

    2013-09-01

    Full Text Available Notwithstanding the enforcement of ATEX EU Directives (94/9/EC of 23 March 1994 and safety management system application, explosions in the coal sector still claim lives and cause huge economic losses. Even a consolidated activity like coke dry distillation allows the opportunity of preventing explosion risk connected to fugitive emissions of coke oven gas. Considering accidental releases under semi-confined conditions, a simplified mathematical approach to the maximum allowed gaseous build-up is developed on the basis of the intrinsic hazards of the released compound. The results will help identifying and assessing low rate release consequences therefore to set-up appropriate prevention and control measures. The developed methodology was tested at the real-scale and validated by numerical computational fluid dynamics (CFD simulations showing the effectiveness of the methodology to evaluate and mitigate the risk connected to confined hazardous releases.

  13. Investigation of thermoluminescence properties of mobile phone screen displays as dosimeters for accidental dosimetry

    Mrozik, Anna; Marczewska, B.; Bilski, P.; Kłosowski, M.

    2014-11-01

    The rapid assessment of the radiation dose after unexpected exposure is a task of accidental dosimetry. In case of a radiological accident glasses originating from mobile phone screens, placed usually near the human body, could be used as emergency thermoluminescent (TL) personal dosimeters. The time between irradiation and TL readout is crucial and therefore preparation of the mobile phone screens and their readout conditions should be optimized. The influence of the samples etching, bleaching and selection of the optical filters based on measurement of the emission spectrum of irradiated glass samples during heating for different types of mobile phones were the subjects of our investigation. Obtained results showed that glasses extracted from different brands of mobile phones have different dosimetric properties but all of them give a luminescent signal which can be used to calculate the dose.

  14. Accidental permutation symmetries as a test for Grand Unification: the supersymmetric $SU(5)$ case

    Fichet, Sylvain

    2016-01-01

    Unification of matter fields implies the existence of accidental permutation symmetries, which potentially remain immune to large quantum corrections up to the TeV scale. We investigate the case of a supersymmetric $SU(5)$ grand unified theory, where such a permutation symmetry is present in the up-type squark sector. We present a variety of tests allowing to challenge the $SU(5)$ hypothesis based on the observation of squarks at the LHC. These tests appear as relations among observables involving flavour-violating or chirality-flipping decays of squarks. Moreover, they rely on top-polarimetry and charm-tagging. As an example, we discuss the application to the scenario of Natural Supersymmetry, while more examples can be found in the related journal publications.

  15. Non-accidental injuries found in necropsies of domestic cats: a review of 191 cases.

    de Siqueira, Adriana; Cassiano, Fabiana Cecília; de Albuquerque Landi, Marina Frota; Marlet, Elza Fernandes; Maiorka, Paulo César

    2012-10-01

    Animal cruelty is defined as a deliberate action that causes pain and suffering to an animal. In Brazil, legislation known as the Environmental Crimes Law states that cruelty toward all animal species is criminal in nature. From 644 domestic cats necropsied between January 1998 and December 2009, 191 (29.66%) presented lesions highly suggestive of animal cruelty. The main necroscopic finding was exogenous carbamate poisoning (75.39%) followed by blunt-force trauma (21.99%). Cats from 7 months to 2 years of age were the most affected (50.79%). In Brazil, violence is a public health problem and there is a high prevalence of domestic violence. Therefore, even if laws provide for animal welfare and protection, animals are common targets for violent acts. Within a context of social violence, cruelty toward animals is an important parameter to be considered, and the non-accidental lesions that were found are evidence of malicious actions.

  16. The use of consequence modelling in assessing accidental releases of activity

    The radiological consequences of an accidental release can be expressed as the number of health effects in the exposed population and its descendents, and the economic and social implications that may result from restrictions placed on the consumption of foodstuffs, or on the occupation of domestic and commercial premises. For any given release of activity there will be a probability distribution of consequences which will depend on the meteorological characteristics and demographic data particular to the release location. The characteristics of this distribution should be important in reaching judgements on the acceptability of a given site or design. The relative importance of the different endpoints is analysed and the influence of the release location on the resulting distribution is considered. (author)

  18. The assessment of the radiological significance of accidental releases of radionuclides to coastal waters

    Methods are described which enable the radiological consequences of an accidental release of activity to an estuary or sea to be assessed, assuming the release is in the same physical and chemical form as routine discharges. Critical group and collective exposures are considered for the most important seafood ingestion and external radiation pathways. Detailed consideration is given to the interaction of activity with marine sediments, and this enables a more realistic description of any resulting radiation exposure to be given than is possible by using existing mathematical models more suited to extended releases of radionuclides. The methods employed constitute an interesting use of a powerful technique involving the numerical inversion of Laplace transformed quantities. (author)

  19. Forensic aspects of paediatric fractures. Differentiating accidental trauma from child abuse

    Fractures are a common finding in children and it is estimated that 2.1% of all children will suffer at least one fracture before the age of 16. With young children in particular, the question may arise if this is related to child abuse. The aim of this book is to help physicians involved in child abuse cases to interpret radiological findings in light of the forensic circumstances under which they occurred. The authors present up-to-date literature related to the mechanisms underlying non-accidental cases of trauma. In this book not only the radiological findings in child-abuse are discussed, but more importantly, these findings are analyzed from a forensic perspective. Careful attention is paid to evidence regarding reported trauma mechanisms and their clinical outcome; for example, can a fall from a couch result in a femoral fracture, and if not, where is the supporting evidence?

  20. The accidental release of exotic species from breeding colonies and zoological collections.

    Barrat, J; Richomme, C; Moinet, M

    2010-04-01

    Exotic species have often been introduced into a new country in zoological or botanical gardens or on game and fur farms. When accidentally or deliberately released, these alien species can become invasive and have negative impacts on native plant and animal communities and human activities. This article focuses on a selection of such invasive species: principally the American mink (Neovison vison), but also the coypu (Myocastor coypus), muskrat (Ondatra zibethicus), raccoon dog (Nyctereutes procyonoides), raccoon (Procyon lotor) and African sacred ibis (Threskiornis aethiopicus). In each of these cases, the authors describe the biological characteristics and life history of the species, in relation to its invasive capacity, the origins and establishment of non-native populations, the environmental consequences and possible control measures. The main negative impacts observed are the destruction of habitat, the introduction and/or spread of pathogens and changes in the composition of native communities with consequent effects on biodiversity.

  2. Summary of accidental releases of radioactivity detected off the Nevada Test Site, 1963--1986

    Of the more than 450 underground nuclear explosives tests conducted at the Nevada Test Site from August 1963 (signing of the Limited Test Ban Treaty) through the end of 1986, only 23 accidentally released radioactivity that was detectable beyond the boundary of the NTS. Of these 23, 4 were detectable off the NTS only by aircraft while the remainder were detectable by ground monitoring instruments. Since the Baneberry venting of December 1970, only two tests released radioactivity that was detectable off the NTS, and this was a seepage of radioactive noble gases. None of these releases from underground tests designed for complete containment caused exposure of the population living in the area that exceeded standards recommended by national and international radiation protection agencies. This report summarizes the releases from each of the tests, describes the monitoring that was conducted, and lists the location of the maximum exposure

  3. The European Community dimension to the problem of accidental radioactive releases to the environment

    The European Community has to comply with the provisions of the Euratom Treaty, 1957. As well as providing the conditions necessary for the growth of nuclear industries it lays down the task to establish uniform Safety Standards to protect the health of workers and of the general public. This includes emergency planning in case of nuclear accidents. As a result the Community followed the guide, published in 1982 by the International Commission on Radiological Protection, on the radiological protection criteria for controlling doses to the public in the event of accidental releases of radioactive materials. However when the Chernobyl accident occured the Community and International arrangements proved to be inadequate to respond to the consequent widespread contamination over Europe. Measures have been taken since then to improve the preparedness of the Community. They include better exchange of information, control of contaminated foodstuffs and better information to the public.

    2015-07-01

    Designing new functional materials with increasingly complex compositions is of current interest in science and technology. Complex rare-earth-based chalcogenides have specific thermal, electrical, magnetic and optical properties. Tetragadolinium bis[tetraoxidosilicate(IV)] oxide telluride, Gd4(SiO4)2OTe, was obtained accidentally while studying the Gd2Te3-Cu2Te system. The crystal structure was determined by means of single-crystal X-ray diffraction. The compound crystallizes in the space group Pnma. Three symmetry-independent gadolinium sites were determined. The excitation and emission spectra were collected at room temperature and at 10 K. Gd4(SiO4)2OTe appears to be a promising optical material when doped with rare-earth ions. PMID:26146399

  5. Experimental optimization of iodine prophylaxis for prevention of radiation injury from accidental intake of radioiodine

    As is proved by nuclear disaster in Chernobyl Nuclear Power Plant (NPP), iodine prophylaxis may be respected as one of the most urgent and effective methods of prevention of radiation injury of the thyroid gland in the population affected. On the basis of experiments in rats, analytical ways of determination of the dietary iodine intake (iodine supply) of people living around NPP Paks (Hyngary) as well as compartment modelling, experiments it is shown, that for optimization of iodine prophylaxis in masses it is very important to increase the iodine supply upto the recommended values. Combined use of decreased doses of potassium iodide and perchlorate was found to be the optimal way for removal of radioiodine from pregnant organisms and their offsprings following accidental intake of radioiodine

    2006-02-01

    This study analyzes the characteristics of accidental poisoning among children and young adolescents (venomous animals and plants. Increased risk was observed in the 1-3-year age group, due to poisonous substances. Medications (47.5%), pesticides (14.1%), and cleaning products (11.3%) were the main substances involved (284 cases), and 17.2% of children were hospitalized. Among 189 cases of contact with venomous animals and plants, caterpillars (29.1%), bees (25.9%), and spiders (22.8%) were the main agents, with a 1.1% hospitalization rate. Incidence of poisoning is high, and there are important differences in the types of agents involved according to age group, which may help orient the prevention of such accidents. PMID:16501753

    2015-10-01

    As one of the key safety issues of fusion reactors, tritium environmental impact of fusion accidents has attracted great attention. In this work, the dynamic tritium concentrations in the air and human body were evaluated on the time scale based on accidental release scenarios under the extreme environmental conditions. The radiation dose through various exposure pathways was assessed to find out the potential relationships among them. Based on this work, the limits of HT and HTO release amount for arbitrary accidents were proposed for the fusion reactor according to dose limit of ITER. The dynamic results aim to give practical guidance for establishment of fusion emergency standard and design of fusion tritium system. PMID:26164282

    1993-03-01

    The paper indicates the importance of investigating radionuclide translocation in the human food chain, and the contribution of selected food components in total exposure of the population after accidental radioactive contamination. Data on radioactive contamination and risk assessment of the Croatian population after the Chernobyl nuclear accident are given and possibilities of decontamination of food chain components are discussed. Literature data on radionuclide removal from the human food chain are compared to the results of own investigations. Emphasis is placed on biologically most important radionuclides, 131I, 90Sr, 137Cs, and the most effective means of protection are sought. The preventive measures following a nuclear accident should be based on the cost-benefit principle i.e. the damage from applying radiation protection measures should not exceed the benefit from possible dose reduction.

  9. Imaging of accidental contamination with F-18-solution; a quick trouble-shooting procedure

    2016-01-01

    Full Text Available To the best of our knowledge, imaging of accidental exposure to radioactive fluorine-18 (F-18 due to liquid spill has not been described earlier in the scientific literature. The short half-life of F-18 (t½=110 min, current radiation safety requirements, and Good Manufacturing Practice (GMP regulations on radiopharmaceuticals have restrained the occurrence of these incidents. The possibility of investigating this type of incidents by gamma and positron imaging is also quite limited. Additionally, a quick and precise analysis of radiochemical contamination is cumbersome and sometimes challenging if the spills of radioactive materials are low in activity. Herein, we report a case of accidental F-18 contamination in a service person during a routine cyclotron maintenance procedure. During target replacement, liquid F-18 was spilled on the person responsible for the maintenance. The activities of spills were immediately measured using contamination detectors, and the photon spectrum of contaminated clothes was assessed through gamma spectroscopy. Despite protective clothing, some skin areas were contaminated, which were then thoroughly washed. Later on, these areas were imaged, using positron emission tomography (PET, and a gamma camera (including spectroscopy. Two contaminated skin areas were located on the hand (9.7 and 14.7 cm2, respectively, which showed very low activities (19.0 and 22.8 kBq respectively at the time of incident. Based on the photon spectra, F-18 was confirmed as the main present radionuclide. PET imaging demonstrated the shape of these contaminated hot spots. However, the measured activities were very low due to the use of protective clothing. With prompt action and use of proper equipments at the time of incident, minimal radionuclide activities and their locations could be thoroughly analyzed. The cumulative skin doses of the contaminated regions were calculated at 1.52 and 2.00 mSv, respectively. In the follow-up, no skin

    2012-07-01

    Full Text Available Abstract Background Accidental falls among inpatients are a substantial cause of hospital injury. A number of successful experimental studies on fall prevention have shown the importance and efficacy of multifactorial intervention, though success rates vary. However, the importance of staff compliance with these effective, but often time-consuming, multifactorial interventions has not been fully investigated in a routine clinical setting. The purpose of this observational study was to describe the effectiveness of a multidisciplinary quality improvement (QI activity for accidental fall prevention, with particular focus on staff compliance in a non-experimental clinical setting. Methods This observational study was conducted from July 2004 through December 2010 at St. Luke’s International Hospital in Tokyo, Japan. The QI activity for in-patient falls prevention consisted of: 1 the fall risk assessment tool, 2 an intervention protocol to prevent in-patient falls, 3 specific environmental safety interventions, 4 staff education, and 5 multidisciplinary healthcare staff compliance monitoring and feedback mechanisms. Results The overall fall rate was 2.13 falls per 1000 patient days (350/164331 in 2004 versus 1.53 falls per 1000 patient days (263/172325 in 2010, representing a significant decrease (p = 0.039. In the first 6 months, compliance with use of the falling risk assessment tool at admission was 91.5% in 2007 (3998/4368, increasing to 97.6% in 2010 (10564/10828. The staff compliance rate of implementing an appropriate intervention plan was 85.9% in 2007, increasing to 95.3% in 2010. Conclusion In our study we observed a substantial decrease in patient fall rates and an increase of staff compliance with a newly implemented falls prevention program. A systematized QI approach that closely involves, encourages, and educates healthcare staff at multiple levels is effective.

  12. Modelling for radiological and radioecological consequences of an accidental radionuclide release at Sea

    Full text: Scenarios concerning accidental releases of radionuclides into water bodies can be found in the open literature, mostly in connection with nuclear power plants located either onshore or inland. However, meager attention has been given to nuclear reactors used as energy sources for propulsion at sea, which are also subject to accidents. Such potential accidents may involve the loss of part of the reactor core to the surrounding water body. In addition of the initial instantaneous releases, one can estimate delayed source terms based on the rate at which radionuclides are dissolved or leached from the solidified material, like part of the core or structural materials in contact with water. Most of such solidified material might be a mixture of uranium, zirconium, iron, calcium, silica, fission and activation products, and transuranium elements as oxides, forming a glassy type solid. Transport models were used to calculate radionuclide concentrations in water resulting from short and delayed source terms. Oceanographic data used in the calculations were taken either from the open literature or from unclassified reports of the Brazilian Navy, being, however, as generic as possible. Time-dependent concentration functions for radionuclides in aquatic food following an accidental release reflect the net result of intake and elimination processes. However, to avoid the complexities of multiple parameters involved in such processes, the model accounts only for trophic transfer of radionuclides, and yet avoids the necessity of analyzing the details of each transfer step used to determine fish, crustacea, molluscs and seaweed accumulation. Swimming and other aquatic sports are not included in the model used for dose calculations because of theirs relatively low importance in comparison with the pathways concerning ingestion of aquatic food

  13. Non-accidental injury in companion animals in the Republic of Ireland

    McGuinness Kristina

    2005-07-01

    Full Text Available Non-accidental injury (NAI, animal abuse and "battered pet" syndrome are terms used to identify "the intentional harm of an animal". The terms include, but are not limited to, wilful neglect, inflicting injury, pain or distress, or malicious killing of an animal. Three categories of abuse are recognised: physical, sexual and neglect. A postal survey was conducted to determine the extent to which NAI was recognised by veterinary surgeons in urban, semi-rural and rural veterinary practices in the Republic of Ireland. The questionnaire was sent to 600 veterinarians; completed submissions were received from 115 respondents (19.2%. The occurrence of NAI was acknowledged by 106 (92.2% of the respondents and cases had been seen by 50 (43.3% of them, comprised of 36.2% of urban veterinary surgeons from rural towns and of 82% of urban practitioners. In 59% of cases the client indicated the injury was non-accidental; 39 (67.2% of the 58 reported cases involved a single event. Signs that made veterinary surgeons suspicious of NAI included inconsistent history, untreated injuries, recurring injuries, meekness of the animal, suspicious behaviour of the owner and injuries consistent with abuse. The types of injuries observed included burns, lacerations, gunshot wounds, poisoning, injury to genitalia, bruising and fractures. The findings of this study are comparable with those from other countries. Most but not all veterinary surgeons in Ireland recognise NAI and animal abuse is of significant concern in rural and urban communities as evidenced by this survey of practising veterinary surgeons.

  14. Region study of the impact of an accidental radioactive pollution on the corn of winter

    The goal of this study is to evaluate the sensitivity of corn of winter with respect to an accidental release of radioactivity. We want to know if a uniform and specific deposit would involve the same contamination on the scale of the whole territory. the study was based on the equations of the A.S.T.R.A.L. model which makes it possible to evaluate the transfer of the radionuclides in the terrestrial food chain following an accidental atmospheric emission. The parameter of A.S.T.R.A.L. on which the study concentrated is the factor of transfer of the radioactivity of the air to the grain. This factor depends on the parameters of captation and translocation, since harvest is contaminated when the radionuclides deposited on the leaves are assimilated and transported towards the grain. Methodology thus consisted in regionalizing these two parameters. for that, software S.T.I.C.S. (multidisciplinary simulator for standard cultures) developed by the I.N.R.A. of Avignon was used. This model proposes a daily follow-up of the foliar index, as well as the dates of occurrence of the agronomic stages of corn. These variables were correlated with captation and translocation. The outputs of the simulations carried out on 12 climates and 2 varieties made it possible to express the parameters of captation and translocation according to the typology of A.S.T.R.A.L., i e according to the time deposit-harvest. Then, these values were compared with bibliographical data and with data issued from I.R.S.N. programs R.E.S.S.A.C. and R.A.D.E.M.I.C.. (authors)

    A simple core-shell two-dimensional photonic crystal is studied where the triangular lattice symmetry and the C6 point group symmetry give rich physics in accidental touching points of photonic bands. We systematically evaluate different types of accidental nodal points at the Brillouin zone center for transverse-magnetic harmonic modes when the geometry and permittivity of the core-shell material are continuously tuned. The accidental nodal points can have different dispersions and topological properties (i.e., Berry phases). These accidental nodal points can be the critical states lying between a topological phase and a normal phase of the photonic crystal. They are thus very important for the study of topological photonic states. We show that, without breaking time-reversal symmetry, by tuning the geometry of the core-shell material, a phase transition into the photonic quantum spin Hall insulator can be achieved. Here the "spin" is defined as the orbital angular momentum of a photon. We study the topological phase transition as well as the properties of the edge and bulk states and their application potentials in optics. PMID:27505772

    Uma das tarefas que reclamam a atenção de quem se dedica à pesquisa historiográfica no Brasil diz respeito à periodização dos estudos filológicos e lingüísticos produzidos no cenário acadêmico brasileiro, das origens aos nossos dias. A par dos períodos de maior projeção intelectual, dada a riqueza e abundância dos textos escritos sobre a língua, outros mantêm-se à margem da investigação sistemática, fato que inibe uma avaliação mais severa e fidedigna sobre o percurso do pensamento lingüístico em nossa terra. A proposta de periodização que se oferece neste ensaio busca fazer referência a todos os momentos do percurso trilhado pela lingüística e pela filologia no Brasil, com citação de autores e obras mais significativos, sobretudo nos períodos mais antigos, que, por terem completado um ciclo de influências e manifestações no panorama geral dos estudos lingüísticos, prestamse a uma avaliação crítica mais sólida. Já nos períodos mais recentes, são reconhecidos, à semelhança dos demais, como manifestações claras dos processos de continuidade e descontinuidade que caracterizaram a lingüística no Brasil, sem que, entretanto, se possa sobre eles traçar juízo definitivo tendo em vista os efeitos ainda presentes de sua manifestação em nosso cenário acadêmico.

    Full Text Available La città di Venezia, insieme al complesso sistema lagunare di cui fa parte e al quale è strettamente connessa, costituisce un interessante oggetto di studio per quanto riguarda l’equilibrio raggiunto nel tempo fra uomo e acqua, nello specifico, fra processi antropici e dinamiche ambientali. Le tradizionali tecniche costruttive veneziane sono uno degli esempi più evidenti di come l’ingegno umano abbia superato la sfida dell’acqua, riuscendo ad urbanizzare un ambiente inizialmente ostile e a creare le condizioni favorevoli all’abitabilità e ad uno sviluppo economico prevalentemente commerciale. Questo equilibrio era basato sulla profonda conoscenza dei processi naturali che caratterizzavano, e caratterizzano, la laguna e derivava dall’acquisizione di quella sapienza costruttiva generata dalle continue sperimentazioni nella ricerca di fondali idonei, di materiali adeguati e di tecniche rispondenti ad esigenze sempre più complesse, con un’estrema attenzione al territorio e alle sue risorse.Con l’affermarsi dell’era industriale, nel corso del diciannovesimo secolo, Venezia riformula le sue strategie di sviluppo puntando sulla costruzione di una nuova base industriale connessa al porto e sulla promozione turistica dell’isola. Il superamento della capacità di carico è sicuramente uno dei più consistenti punti di rottura di quel delicato equilibrio su cui è stata fondata la città fin dalle sue origini.L’articolo presenta una proposta progettuale di riconfigurazione della Marittima di Venezia basata sulla ridistribuzione dei flussi turistici e sull’incremento di resilienza del sistema economico, sociale ed ambientale della città, puntando sul porto come importante risorsa strategica per il territorio. 

  3. Individualismo metodológico, racionalidade e ação instrumental: a proposta cognitiva de Raymond Boudon

    Full Text Available O artigo analisa as proposições teóricas do individualismo metodológico de Raymond Boudon, que procura desvincular-se de perspectivas que ressaltam a concepção de racionalidade instrumental, como o entendimento da escolha racional. As diferenças entre a conduta instrumental e a idéia de racionalidade cognitiva propostas pelo sociólogo envolvem temas centrais da reflexão social atual, principalmente possíveis vínculos problemáticos entre a tradição sociológica e certa ontologia econômica. Para mostrar a particularidade do individualismo metodológico de Boudon e sua noção de racionalidade cognitiva, exponho, primeiramente, as suas principais críticas ao paradigma instrumental. Posteriormente, debato as alternativas sugeridas por Boudon, principalmente a idéia de que os agentes incorporam crenças ou teorias simplesmente porque têm "boas razões" e a sua noção de uma "racionalização difusa". Finalmente, procuro analisar de que forma a teoria do autor francês aponta falhas da visão economicista de racionalidade, embora apresente algumas proposições imprecisas. Assim, ao mesmo tempo em que assinala importante falta de conexão entre a agência individual e o contexto social na teoria da escolha racional, Boudon elabora uma concepção universalista de racionalidade que parece não observar fundamentos circunstanciais e delimitados da realidade social.

  4. The influence of season of the year on the predicted agricultural consequences of accidental releases of radionuclides to atmosphere

    In Europe, because of the seasonal nature of agricultural practices, the consequences for agriculture of an accidental release of radioactive materials to atmosphere are likely to vary depending upon the time of year when the release occurs. The quantification of this variation is complicated by the need to take into account the introduction of countermeasures to restrict the radiation exposure from ingestion of contaminated foods, and by the presence in accidental releases of radionuclides which persist over several seasons. In this study, the effect on agricultural consequences of accidental releases occurring at different times of the year is examined. The consequences are expressed in terms of the amount of produce affected by restrictions on food supplies and the collective radiation dose from ingestion of food. The investigation has been carried out for three hypothetical releases representing a range of releases postulated for pressurised water reactors (PWRs). The effect of season of the year was determined for accidental releases occurring both in a single, defined set of meteorological conditions and for a range of possible meteorological conditions. For the main part of the study, consideration was limited to agricultural production in the UK only, but the effect of extending the analysis beyond the UK boundary was also considered. The results of the study show that considerable variation can occur in agricultural consequences following an accidental release at different times of the year. For the larger releases considered, this variation is reduced due to the effect of the introduction of countermeasures, particularly when consideration is limited to the UK only. Seasonal variation tends to be greater for the results of a deterministic analysis, which uses a single set of constant meteorological conditions, than for the results of a full probabilistic assessment. From the results presented here it is also seen that for many applications of

  10. Dispersion modeling of accidental releases of toxic gases - utility for the fire brigades.

    Stenzel, S.; Baumann-Stanzer, K.

    2009-09-01

    Several air dispersion models are available for prediction and simulation of the hazard areas associated with accidental releases of toxic gases. The most model packages (commercial or free of charge) include a chemical database, an intuitive graphical user interface (GUI) and automated graphical output for effective presentation of results. The models are designed especially for analyzing different accidental toxic release scenarios ("worst-case scenarios”), preparing emergency response plans and optimal countermeasures as well as for real-time risk assessment and management. The research project RETOMOD (reference scenarios calculations for toxic gas releases - model systems and their utility for the fire brigade) was conducted by the Central Institute for Meteorology and Geodynamics (ZAMG) in cooperation with the Viennese fire brigade, OMV Refining & Marketing GmbH and Synex Ries & Greßlehner GmbH. RETOMOD was funded by the KIRAS safety research program of the Austrian Ministry of Transport, Innovation and Technology (www.kiras.at). The main tasks of this project were 1. Sensitivity study and optimization of the meteorological input for modeling of the hazard areas (human exposure) during the accidental toxic releases. 2. Comparison of several model packages (based on reference scenarios) in order to estimate the utility for the fire brigades. For the purpose of our study the following models were tested and compared: ALOHA (Areal Location of Hazardous atmosphere, EPA), MEMPLEX (Keudel av-Technik GmbH), Trace (Safer System), Breeze (Trinity Consulting), SAM (Engineering office Lohmeyer). A set of reference scenarios for Chlorine, Ammoniac, Butane and Petrol were proceed, with the models above, in order to predict and estimate the human exposure during the event. Furthermore, the application of the observation-based analysis and forecasting system INCA, developed in the Central Institute for Meteorology and Geodynamics (ZAMG) in case of toxic release was

  13. Therapeutic strategies for the treatment of accidental radiation-induced hematopoietic syndrome

    The hematopoietic syndrome induced by large field high dose accidental irradiation remains difficult to treat, mainly due to the heterogeneity of irradiation. As a result, there always remains an area of active hematopoiesis that was partly protected from irradiation. The choice of a therapeutic strategy thus must be based upon the estimate of radiation damage to the bone marrow. This can be achieved by the use of biological indicators of damage to specific organs. With this respect, we recently showed that the follow up of Flt3 ligand concentration in the blood allowed a direct evaluation of residual hematopoiesis soon after irradiation in animal models as well as in humans. Nevertheless, the possible therapeutic strategies available for the treatment of radiation-induced hematopoietic syndrome are limited to the choice between either stem cell transplantation or supportive care. Recently, the use of autologous cell therapy was proposed. The principle is to harvest the hematopoietic cells surviving to irradiation, to expand these cells in vitro and to re inject these cells to the patient. This is based upon the existence of a residual hematopoiesis and on the possibility to expand in vitro irradiated hematopoietic cells. Experimental work in a non human primate model of high-dose, heterogeneous irradiation showed that it was possible to harvest surviving hematopoietic cells after irradiation and to amplify these cells in vitro. However, the therapeutic efficiency of the reinjected cells was limited by the occurrence of a combined disease, implicating the lungs, the kidney and the liver, but also a severe vascular damage. Such a multiple organ disease syndrome induced by ionizing radiations was already observed in two radiation accidents, the Tokai MURA accident and the Neshvish accident. In an attempt to accelerate the hematopoietic recovery, we combined autologous cell therapy with G-CSF injections in the same model of heterogeneous irradiation with non human

    Despite the well-recognised benefits of sport, there are also negative influences on athlete health, well-being and integrity caused by non-accidental violence through harassment and abuse. All athletes have a right to engage in 'safe sport', defined as an athletic environment that is respectful, equitable and free from all forms of non-accidental violence to athletes. Yet, these issues represent a blind spot for many sport organisations through fear of reputational damage, ignorance, silence or collusion. This consensus statement extends the 2007 IOC Consensus Statement on Sexual Harassment and Abuse in Sport, presenting additional evidence of several other types of harassment and abuse-psychological, physical and neglect. All ages and types of athletes are susceptible to these problems but science confirms that elite, disabled, child and lesbian/gay/bisexual/trans-sexual (LGBT) athletes are at highest risk, that psychological abuse is at the core of all other forms and that athletes can also be perpetrators. Harassment and abuse arise from prejudices expressed through power differences. Perpetrators use a range of interpersonal mechanisms including contact, non-contact/verbal, cyber-based, negligence, bullying and hazing. Attention is paid to the particular risks facing child athletes, athletes with a disability and LGBT athletes. Impacts on the individual athlete and the organisation are discussed. Sport stakeholders are encouraged to consider the wider social parameters of these issues, including cultures of secrecy and deference that too often facilitate abuse, rather than focusing simply on psychopathological causes. The promotion of safe sport is an urgent task and part of the broader international imperative for good governance in sport. A systematic multiagency approach to prevention is most effective, involving athletes, entourage members, sport managers, medical and therapeutic practitioners, educators and criminal justice agencies. Structural and

  15. Impact study of an accidental pollution and an agricultural pollution on the subsoil water resources

    This work deals with the protection of groundwater resources against accidental and agricultural pollutions. It comprises three parts: part 1 is a bibliographic analysis of pollutants transfer mechanisms in the non-saturated zone. It presents the techniques of numerical resolution of the equations controlling these transfers (mechanistic approach). Approaches of data processing-type are also presented. The advantage of neural networks, more and more used in the environmental domain, is emphasized. The second part treats of the migration of non-miscible pollutants (of hydrocarbon or chlorinated solvent type) in the non-saturated zone from an accidental pollution source (a road accident). After a bibliographic analysis of the reference accident, of the most often road transported pollutants and of the available softwares, the area under study is presented with the tests performed at the laboratory for the determination of the permeability coefficient at saturation and the Van Genuchten parameters of the covering layer. The results of the parametric study are given for a reference example using the NAPL-Simulator code. This study allows to outline the main parameters which are used for the construction of a database for the calibration of the neural network-based model. This model is used in the case of the impact study of the road works between Avesnes-sur-Helpes and Maubeuge carried out on the captation fields of Bachant syncline. The third part treats of the migration of a diffuse pollution of agricultural origin (nitrates) in the non-saturated zone. The area under study is presented with the in-situ follow up results of surface fertilizer supplies and of nitrate profile measurements performed for some logging. The construction of the database is detailed. The input data retained are the surface nitrogen supplies, the thickness of the soil beneath the root zone, the water table depth and the time. Finally, the artificial neural networks model and its application to

  17. Report of the consultant's meeting on monitoring accidentally released radionuclides in the environment

    At an earlier Research Co-ordination Meeting (12-16 August 1991, VIC, Vienna) for the IAEA Programme on 'Rapid Instrumental and Separation Methods for Monitoring Radionuclides in Food and Environmental Samples', it was recognized that a network of analytical laboratories with specially qualified scientists is needed which will provide a timely coordinated response to any future requests for assistance from Member States. The experience gained from the International Chernobyl Project revealed that there is a need for such a closely linked group when the Member State lacks sufficient technical resource to independently perform an assessment of environmental contamination following an accidental release of radioactivity. The existence of such a network of laboratories would help to assure responsible government representatives and the general public that the Agency has additional available resources including specialized experts to perform assessments on which to base required actions for many accident scenarios and their radiological consequences. The purpose of the present Consultants' Meeting is to discuss the organization and scope of the proposed network of analytical laboratories. The Consultants should discuss the matrices and nuclides of interest at various time frames of an accidental release of radioactivity. It is also intended that the Consultants should discuss the laboratories from their experience which would have the specialized expertise needed, in both terrestrial and aquatic sample collection and analysis. Finally, it is intended that the Consultants should discuss whether it would be desirable for the Agency to produce a technical document based on the achievements of the Agency programme on 'Rapid Instrumental and Separation Methods for Monitoring Radionuclides in Food and Environmental Samples'. A Guide Book was considered essential by the participants of this Co-ordinated Research Programme because it would be a succinct form and on a common

    The Fukushima nuclear accident resulted in the largest ever accidental release of artificial radionuclides in coastal waters. This accident has shown the importance of marine assessment capabilities for emergency response and the need to develop tools for adequately predicting the evolution and potential impact of radioactive releases to the marine environment. The French Institute for Radiological Protection and Nuclear Safety (IRSN) equips its emergency response centre with operational tools to assist experts and decision makers in the event of accidental atmospheric releases and contamination of the terrestrial environment. The on-going project aims to develop tools for the management of marine contamination events in French coastal areas. This should allow us to evaluate and anticipate post-accident conditions, including potential contamination sites, contamination levels and potential consequences. In order to achieve this goal, two complementary tools are developed: site-specific marine data sheets and a dedicated simulation tool (STERNE, Simulation du Transport et du transfert d'Eléments Radioactifs dans l'environNEment marin). Marine data sheets are used to summarize the marine environment characteristics of the various sites considered, and to identify vulnerable areas requiring implementation of population protection measures, such as aquaculture areas, beaches or industrial water intakes, as well as areas of major ecological interest. Local climatological data (dominant sea currents as a function of meteorological or tidal conditions) serving as the basis for an initial environmental sampling strategy is provided whenever possible, along with a list of possible local contacts for operational management purposes. The STERNE simulation tool is designed to predict radionuclide dispersion and contamination in seawater and marine species by incorporating spatio-temporal data. 3D hydrodynamic forecasts are used as input data.
