    The radiological accident happened in the Chilca District, the Canete County at 60 km to the south of Lima-Peru, during the night of January 11 to 12, 2012. The physical reconstruction of the accident was carried out in January 21, 2012, by means of the information gathering administrative and technical of the radioactive source as well as of the installation, the personnel and the involved procedures in the accidental event, information of the space geometry where the event took place. The preliminary information indicates that the source could have been locked in the guide tube of the equipment, next to the collimator in the first takes radiographic. The radiation monitors were not activated on the procedure, impeding this way, not to realize the flaw and causing that the personnel were exposed to the radiation during the whole work period. Their hands and especially their fingers would have been only to some millimeters of the source. With the obtained information and the measurements of the exposure rates of the radioactive source, was carried out the dose calculation to total body, the dose received in the hands and the dose received in the index finger of the left hand. The accident happened by operative procedure breach, by lack of training of the operators. The physical reconstruction of the accident contributes fundamental information for the decisions taking in the medical management of the accidents by radiation. (author)

    The greatest fear of the population before a nuclear accident, is the radiological impact to the health of people, due to the exposure to the liberated radioactive material during the accident, this fear is generally exaggerated or not well managed by the media. The best estimate in the received doses and their possible effects is carried out based on the information obtained during a certain time after the accident event. This work contains a summary of the information in the topic that at the present time has presented institutions as: the World Health Organization (Who), the United Nations Scientific Committee on Effects of Atomic Radiation (UNSCEAR), the Nuclear Regulatory Commission (NRC) and the World Nuclear Association, among others. The considered accidents are: first, the Unit-2 of the nuclear power plant of the Three Mile Island in Pennsylvania, USA occurred 28 March of 1979, in the Reactor TMI-2, type PWR of 900 M We; the second accident was 26 April of 1986, in the Unit-4 of the nuclear power plant of Chernobyl, in Ukraine, the involved reactor was type BRMK, of 1000 M We moderated by graphite and cooled with light water, the power plant is located to 100 Km to the northwest of Kiev; 25 years later occurred the third accident in the nuclear power plant of Fukushima Dai-ichi, in Japan, affecting at four of the six reactors of the power plant. A brief description of the accident is presented in each case, including the magnitude of the provoked liberations of radioactive material, the estimate doses of the population and the affected workers are presented, as well as the possible consequences of these doses on the health. The objective of this diffusion work is to give knowledge to the nuclear and radiological community of the available information on the topic, in order to be located in the appropriate professional context.

    On September 20, 2005 when a mission conformed by five (05) officials: two (02) belonging to the Ministry of Energy and Mines (MEP) and three (03) of the Ministry of Health (MS) it was prepared to carry out a routine inspection in the one temporary warehouse of sources in disuse located in La Ciudadela of El Cementerio, identified administratively as Warehouse Number 5 (MS) Area X, noticed that those armor-plating that kept the radioactive sources of Cs-137 had been violated. Those people that entered to the warehouse were able to extract the armor-plating in whose interior its were found an important number of sources of Cs-137 in disuse, used in the decade of 70 and 80 in treatment of cancer of the uterine neck, by means of the Brachytherapy technique of Differed charge manual, low dose rate, as well as, lead sheets with the apparent intention of selling them as junk. The intruders extracted a total of 58 radioactive sources of Cs-137 of its armor-plating for then to disperse them inside warehouse and in the external areas to this. An important number of the dispersed sources its had lost it integrity what gave place to a combined scenario of exposed dispersed sources in a public area with the danger of radioactive contamination by Cs-137. A task force conformed by the following institutions: Ministry of Health (MS), Ministry of Energy and Petroleum (MENPET), Venezuelan Institute of Scientific Investigations (IVIC), Unit of Dangerous Materials of the Metropolitan Firemen under the coordination of Civil Protection (PC) it was the one in charge of responding to the radiological accident, of conformity to the National Plan for the Answer to Radiological Accidents. All the radioactive sources dispersed in La Ciudadela achieved to be recovered. The experience of the accident and as learned lesson it was the importance of harmonizing the Generic Procedures for the Evaluation and Answer during Radiological Emergencies, IAEA-TECDOC-1162 technical document, Vienna, August 2000, with the procedures of the answering in charge of responding to accidents with dangerous materials.

    Derived of the radioactive or nuclear material management, exists the risk that accidents can happen where people cases are presented with internal radioactive contamination, who will receive specialized medical care to accelerate the radioactive dis incorporation with the purpose of diminishing the absorbed dose and the associate biological effects. In this work treatments of radioactive dis incorporation were identified, in function of the radionuclide, radiation type, radioactive half life, biological half life, critical organ, ingestion duct and patient type. The factor time is decisive for the effectiveness of the selected treatment in the blockade stage (before the accident) or dis incorporation (after the accident); this factor is related with the radioactive and biological half lives. So to achieve dis incorporation efficiencies of more to 70%, the patient clinical treatment will begin before the first third of the biological half life of the radionuclide that generated the internal contamination.

    The scope of radiological analysis is to calculate the dose received by the public and by an operator in the control room in case of an accident. Simulation software are needed for that kind of analysis in order to solve differential equations (radionuclides transport equations), to simulate the accident scenario, and to calculate the dose. This article presents the main radionuclide transport codes (several cases simulated with RADTRAD v3.03 are detailed), dose calculation programs, and atmospheric dispersion coefficients calculation software.

    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...

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.

    We consider a new approach to fermion masses and mixings in which no special 'horizontal' dynamics is invoked to account for the hierarchical pattern of charged fermion masses and for the peculiar features of neutrino masses. The hierarchy follows from the vertical, family-independent structure of the model, in particular from the breaking pattern of the Pati-Salam group. The lightness of the first two fermion families can be related to two family symmetries emerging in this context as accidental symmetries.

    Full Text Available Haloperidol, a butyrophenone neuroleptic drug, is an antipsychotic used in the treatment of adult schizophrenia and mania. It is used in children with neurological disorders like chorea and developmental disorders such as hyperactivity. With the advent of newer selective neuroleptics use of haloperidol is now on decline. However, in adults it is still the preferred drug especially in resource challenged settings. Extrapyramidal reactions occur frequently with haloperidol predominantly as parkinsonian symptoms. There are few case reports of accidental haloperidol poisoning in children and this one of them.

    In this paper a classification of the radiological and nuclear accidents is presented, describing which the activities are, where they have occurred, their incidence and the learned lessons in these successes. The radiological accidents in which radioactive materials intervene can occur anywhere, and they are related to no controlled dangerous sources (abandoned, lost, stolen, or found sources), improper use of dangerous industrial and medical sources, exposition and contamination of people in general by an unknown origin, serious over expositions, menaces and willful misconduct, emergencies during transportation of radioactive material. A person can receive a dose of radiation from an external source, because of radioactive material placed on skin or on equipment, or because of ingestion or inhalation of radiological particles. The ingestion or the inhalation of radioactive material can cause an internal dose to the whole body or to a specific organ during a period of time. That is why a description of the processes of incorporation, the stages of incorporation and a description of the biokinetic models are also realized to understand the ingestion, transference and the excretion of the radioactive elements. In order to offer help to a victim of internal contamination, the dosimetric and medical diagnosis is very important. The most important techniques of dosimetric diagnosis are the dosimetry in vivo (cytogenetics and the counting in vivo of the whole body) and the bioassays. These techniques allow obtain data such as the radionuclide, the target organ, the absorbed dose, etc. At the same time, the doctor in charge must be attentive to the patients symptoms and their manifestation time, since they are an indicator, first, the patient suffered an irradiation, and second, of the range esteem of the received radiation dose. These are the parameters that are useful as criterion to decide if a person has to receive some treatment and select the methodologies that allow obtain a better result of the dis incorporation of the radioactive material. In this work, the attention is focused on the identification, classification and selection of the methodologies to accelerate the dis incorporation of radionuclides in people related to nuclear a radiological accidents, depending on the way of incorporation to the human body, the radionuclide, the radiotoxicity, the kind of radiation and its energy, the chemical compound, the half-life of the radioisotope, the target organ, the esteem of the absorbed dose, the characteristic of the accident, the clinical state of the patient and how long ago the accident happened.

  6. Accidental inflation in the landscape

    International Nuclear Information System (INIS)

    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

    The Direccion de Vigilancia Radiologica (DVR) of the Comision Nacional de Seguridad Nuclear y Salvaguardias (CNSNS) de Mexico, performs several function for environmental radiation monitoring. One of these functions is the permanent monitoring of the environmental gamma radiation. For this, it implemented the Red Nacional Automatica de Monitoreo Radiologico Ambiental (RENAMORA) - the National Automated Network for Environmental Radiation Monitoring,which currently comprises 60 detector probes for gamma radiation which with a programmable system that includes information technologies, data transmission and software can send the information in real time to a primary center of data located in the facilities of CNSNS. - When the data are received, the system performs the verification and extraction of the information organized in Tables and charts, and generates a report of environmental gamma radiation dose rate average for each of the probes and for each period of time determined bu CNSNS. The RENAMORA covers the main cities and allows to establish the bases of almost the entire country, as well as to warn about abnormal situations caused by incidents or natural events generated by human activities inside or outside the country which involves radioactive materials; paying special attention to main radiological sites, such as the surroundings of the Laguna Verde Nuclear Power Plants, research centers and the radioactive waste disposal sites.

    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.

    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.

    Full Text Available La admiratividad ("mirativity", en inglés se define ampliamente como la marcación gramatical de un enunciado con respecto a una información inesperada para el hablante. Más específicamente, corresponde al correlato lingüístico de la sorpresa frente a una información inesperada. La admiratividad puede manifestarse como una categoría gramatical encubierta o abierta, y como una categoría opcional u obligatoria, según la gramática de cada lengua. Si bien el español no ha morfologizado la admiratividad, el presente estudio propone, a partir del análisis de casos de un corpus de foros de Internet en español de Chile, la existencia de una construcción admirativa que responde al modelo "¡No se me había ocurrido nunca!". Dicha construcción presenta restricciones específicas que afectan, fundamentalmente, al tipo de predicado, el marco de predicación, la estructura informativa y la fuerza ilocutiva. (Mirativity refers to the grammatical marking of unexpected information. More precisely, it is the linguistic expression of the surprise which unexpected information provokes in the speaker. Mirativity can be codified as an overt or a covert grammatical category, and as an optional or an obligatory category, depending on the grammar of the language. There are no mirative morphemes in Spanish language; nevertheless, a corpus study of Internet message boards written in Chilean Spanish shows that clauses such as "¡No se me había ocurrido nunca!" can be described as a mirative construction. This construction presents specific constraints on type of predicate, predication frame, information structure and illocutionary force.

    Directory of Open Access Journals (Sweden)

    Fahmy Aboulenein-Djamshidian

    Full Text Available To date, no direct scientific evidence has been found linking tissue changes in multiple sclerosis (MS patients, such as demyelination, axonal destruction or gliosis, with either steady progression and/or stepwise accumulation of focal CNS lesions. Tissue changes such as reduction of the retinal nerve fiber layer (RNFL and the total macular volume (TMV, or brain- and spinal cord atrophy indicates an irreversible stage of tissue destruction. Whether these changes are found in all MS patients, and if there is a correlation with clinical disease state, remains controversial. The objective of our study was to determine, whether there was any correlation between the RNFL or TMV of patients with MS, and: (1 the lesion load along the visual pathways, (2 the ratios and absolute concentrations of metabolites in the normal-appearing white matter (NAWM, (3 standard brain atrophy indices, (4 disease activity or (5 disease duration.28 MS patients (RRMS, n = 23; secondary progressive MS (SPMS, n = 5 with moderately-high disease activity or long disease course were included in the study. We utilised: (1 magnetic resonance imaging (MRI and (2 -spectroscopy (MRS, both operating at 3 Tesla, and (3 high-resolution spectral domain-OCT with locked reference images and eye tracking mode to undertake the study.There was no consistency in the pattern of CNS metabolites, brain atrophy indices and the RNFL/TMV between individuals, which ranged from normal to markedly-reduced levels. Furthermore, there was no strict correlation between CNS metabolites, lesions along the visual pathways, atrophy indices, RNFL, TMV, disease duration or disability.Based on the findings of this study, we recommend that the concept of 'clinico-radiologico paradox' in multiple sclerosis be extended to CROP-'clinico-radiologico-ophthalmological paradox'. Furthermore, OCT data of MS patients should be interpreted with caution.

    Toddlers who ingest the drug of abuse 3,4-methylenedioxymethamphetamine (MDMA; 'Ecstasy') are at particularly high risk of serious neurological and cardiovascular side effects. We report of a 20-month-old male toddler who accidentally ingested Ecstasy. He presented with fever and seizures, tachycardia, hypertension, and hyperthermia. Urine amphetamine level was 2111 ng/mL. Treatment included rapid cooling, hydration, and support measures. Vital signs were regularly monitored. His condition became stable on day 2 and urine amphetamine level returned to normal on day 3 of hospitalization. His behavior, activity, and appetite had returned to their usual levels upon follow-up at our outpatient clinic. The incidence of drug abuse with MDMA has increased dramatically over the last decade in developed countries. It can be expected that accidental Ecstasy poisoning in children will increase as well. This case illustrates the need to consider the possibility of accidental Ecstasy ingestion in the differential diagnosis of a child suffering from convulsions with fever.

    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.

    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

  1. Medical management of accidentally exposed individuals

    International Nuclear Information System (INIS)

    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)

    The modern surgical endodontic treatment is a safe and predictable procedure with high success rate. However, several factors can retard or impede the proper healing process. Use of a high speed handpiece during hard tissues management (osteotomy and apical resection) can potentially be one of these factors. Formation of metallic debris from the surgical diamond burs, production of necrotic local tissue due to overheating and the direct liberation of air from conventional handpiece into the working area are potential irritants able to delay the tissue healing. The aim of the present article is to report the histopathological findings of the trans-operational accidental contamination with oil in the surgical area during an endodontic surgery. PMID:27790269

    Full Text Available Accidental hypothermia refers to a state of lowering of core body temperature down to 35 ℃induced by drowning, burial in snow and prolonged exposure to cold environment, etc. Hypothermia may affect the cardiovascular system, respiratory system, digestive system, etc. The triad consisting "hypothermia, acidosis and coagulopathy" is an important factor accelerating the death of patients. Early, timely application of rewarming measures is regarded as the basic principle in treatment of hypothermia. A series of rewarming measures, such as infusion of warm fluids, inspiration of warm air, abdominal infusion of warm fluid, instruction of warm fluid into pleural cavity, intravenous infusion of warm fluid, rewarming through ECMO, etc. have been used recently. Advance in research on the classification of hypothermia, its impact to the body and the treatment methods are reviewed in present paper. DOI: 10.11855/j.issn.0577-7402.2016.04.15

    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.

    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.

    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.

    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)

    Removal half-life (RHL) of tritium is one of the best means for optimising medical treatment, reduction of committed effective dose (CED) and quick/easy handling of a large group of workers for medical treatment reference. The removal of tritium from the body depends on age, temperature, relative humidity and daily rainfall; so tritium removal rate, its follow-up and proper data analysis and recording are the best techniques for management of accidental acute tritium exposed cases. The decision of referring for medical treatment or medical intervention (MI) would be based on workers' tritium RHL history taken from their bodies at the facilities. The workers with tritium intake up to 1 ALI shall not be considered for medical treatment as it is a derived limit of annual total effective dose. The short-term MI may be considered for tritium intake of 1-10 ALI; however, if the results show intake ≥100 ALI, extended strong medical/therapeutic intervention may be recommended based on the severity of exposure for maximum CED reduction requirements and annual total effective dose limit. The methodology is very useful for pressurized heavy water reactors (PHWRs) which are mainly operated by Canada and India and future fusion reactor technologies. Proper management will optimise the cases for medical treatment and enhance public acceptance of nuclear fission and fusion reactor technologies.

Asimismo en la actualidad se reconoce la importancia del recurso humano para la organización y surge el concepto de "presentismo", referido a aquellos trabajadores que sufren enfermedades que los obligarían a ausentarse del trabajo pero que se presentan a trabajar sin cumplir eficazmente sus funciones. Al respecto y en relación con el presentismo, se debe tomar en cuenta que los efectos adversos o accidentes durante la atención de servicios de salud se encuentran asociados a factores fisiológicos, psicológicos y ambientales e implican desde el punto de vista administrativo, una falla en la productividad, que afecta tanto al usuario del servicio como al trabajador. Se debe considerar que este grupo profesional se ubica entre los grupos de riesgo del presentismo y que con el fin de administrar y reducir el presentismo se requieren estrategias preventivas por parte de la gerencia de salud.

    Fifty children who were referred to the child abuse team in Leeds over the 10 years 1976-86 with suspected non-accidental injury were found to have conditions which mimicked non-accidental injury. These included impetigo (nine children) and blue spots (five children). Five children who presented with multiple bruising had haemostatic disorders. Eight children had disorders of the bone. Five children had been previously abused physically. Four showed evidence of neglect. One had evidence of no...

    2014-01-01

    One of the complications during a routine dental implant placement is accidental ingestion of the implant instruments, which can happen when proper precautions are not taken. Appropriate radiographs should be taken to locate the correct position of foreign body; usually the foreign body passes asymptomatically from gastrointestinal tract but sometimes it may lead to intestinal obstruction, perforations and impactions. The aim of this article is to report accidental ingestion of 19 mm long scr...

  19. Accidental oil spills - project management strategy

    International Nuclear Information System (INIS)

    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

    A two year prospective study was performed to determine the epidemiology of Munchausen syndrome by proxy, non-accidental poisoning, and non-accidental suffocation in the UK and the Republic of Ireland. Cases were notified to the British Paediatric Association Surveillance Unit from September 1992 to August 1994 if a formal case conference had been held for the first time during that period to discuss any of the above conditions. A total of 128 cases were identified: 55 suffered Munchausen syndrome by proxy alone, 15 poisoning, and 15 suffocation; 43 suffered more than one type of abuse. The majority of children were aged under 5 years, the median age being 20 months. On 85% of occasions the perpetrator was the child's mother. In 42% of families with more than one child, a sibling had previously suffered some form of abuse. Eighty five per cent of notifying paediatricians considered the probability of their diagnosis as virtually certain before a case conference was convened. The commonest drugs used to poison were anticonvulsants; opiates were the second commonest. Sixty eight children suffered severe illness of whom eight died. The combined annual incidence of these conditions in children aged under 16 years is at least 0.5/100,000, and for children aged under 1, at least 2.8/100,000.

    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

    The aim of the present cross-sectional survey was to assess factors associated with non-accidental collision followed by dental trauma among adolescents in the city of Diamantina, Brazil. A total of 387 students from 12 to 15 years of age (mean = 14 SD = 0.9) were randomly selected. The study was carried out in two stages. Firstly, data were collected through dental examinations of permanent incisors. Secondly, a thorough interview was held with 85 adolescents who exhibited dental trauma in the dental examinations. The interview consisted of a detailed description of the incident and physical environment in which it occurred. Descriptive analysis and the chi-square test (P 3 mm (P = 0.007) and inadequate lip coverage (P = 0.013). Analysis of the event revealed that 22.3% of the cases of dental trauma occurred because of non-accidental collision. Non-accidental collision followed by injury occurred mainly at school (P concrete, tiled or ceramic floor (P = 0.001). No statistically significant associations were found between non-accidental collision and gender, age or mother's schooling. It was concluded that the non-accidental collisions happened especially at school and in indoor environments with a concrete, tiled or ceramic floor.

    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

    Full Text Available ABSTRACT: Electro - fishing (passing electricity through water to catch fish requires sophisticated equipment. While this method is commonly employed b y scientists for survey and fisheries management, a crude and illegal form electro - fishing is employed in Kerala for catching fish from water bodies. This can result in accidental electrocution and even fatalities. Even though they are rare, forensic patho logists in Kerala do come across such deaths from time to time. 8 cases of accidental death which occurred during electro - fishing are discussed here.

  5. 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.

    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

  7. 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

    2016-09-01

    Food allergies are a growing problem and currently the primary treatment of food allergy is avoidance of culprit foods. However, given the lack of information and education and also the ubiquitous nature of allergens, accidental exposures to food allergens are not uncommon. The fear of potential fatal reactions and the need of a proper avoidance leads in most of the cases to the limitation of leisure and social activities. This review aims to be a practical approach on education and accidental exposure prevention regarding activities like shopping, eating out, and travelling. The recommendations are focused especially on proper reading of food labels and the management of the disease, namely in restaurants and airplanes, concerning cross-contact and communication with other stakeholders. The implementation of effective tools is essential to manage food allergy outside home, avoid serious allergic reactions and minimize the disease's impact on individuals' quality of life.

    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 ...

    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.

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

    KAUST Repository

    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.

    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

    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\

    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.

    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.

    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

  9. Evaluation and mitigation of accidental releases of radioactivity

    International Nuclear Information System (INIS)

    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)

    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.

    Full Text Available Lacquer thinner, commonly used for removing household paints, is known to contain a mixture of various aromatic hydrocarbons, halogenated hydrocarbons and naptha; if ingested, it may cause methemoglobinemia. We report two cases who presented to us with a history of accidental ingestion of paint thinner. Both the patients had very high levels of methemoglobin and were treated with methylene blue (MB, but did not respond to the MB therapy. One of them received an exchange transfusion followed again by MB and survived. Unfortunately the other patient succumbed to the poisoning.

    We study the complex geometric phase acquired by the resonant states of an open quantum system which evolves irreversibly in a slowly time dependent environment. In analogy with the case of bound states, the Berry phase factors of resonant states are holonomy group elements of a complex line bundle with structure group C*. In sharp contrast with bound states, accidental degeneracies of resonances produce a continuous closed line of singularities formally equivalent to a continuous distribution of "magnetic" charge on a "diabolical" circle, in consequence, we find different classes of topologically inequivalent non-trivial closed paths in parameter space.

    Full Text Available Anisakidosis is a zoonotic disease caused by the ingestion of nematodes belonging to the family of Anisakidae. Human infection is caused by intake of raw or undercooked sea fish and cephalopods infested by Anisakis larvae. We present a case of accidental endoscopic finding of an alive nematode adhering to distal ascending colon in a 32 years old man, submitted to colonoscopy owing to recent onsets of rectal bleeding of likely hemorrhoidal origin. The nematode, removed from colon by means of biopsy forceps, has been identified as L3 larvae of A. simplex by a light microscope. Histological examination of intestinal mucosa showed a mild fibrosis of lamina propria, characterized by focal lymphocytic inflammation and scattered infiltration of eosinophils. The patient reported the intake of marinated anchovies 3 days before endoscopic examination.

    Full Text Available Formalin is a hazardous chemical that needs cautious handling and special storage. 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.

  18. Correcting for accidental correlations in saturated avalanche photodiodes.

    Science.gov (United States)

    Grieve, J A; Chandrasekara, R; Tang, Z; Cheng, C; Ling, A

    2016-02-22

    In this paper we present a general method for estimating rates of accidental coincidence between a pair of single photon detectors operated within their saturation regimes. By folding the effects of recovery time of both detectors and the detection circuit into an "effective duty cycle" we are able to accomodate complex recovery behaviour at high event rates. As an example, we provide a detailed high-level model for the behaviour of passively quenched avalanche photodiodes, and demonstrate effective background subtraction at rates commonly associated with detector saturation. We show that by post-processing using the updated model, we observe an improvement in polarization correlation visibility from 88.7% to 96.9% in our experimental dataset. This technique will be useful in improving the signal-to-noise ratio in applications which depend on coincidence measurements, especially in situations where rapid changes in flux may cause detector saturation.

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

    CERN Document Server

    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.

  1. Subtraction of "accidentals" and the validity of Bell tests

    CERN Document Server

    Thompson, C H

    1999-01-01

    In some key Bell experiments, including two of the well-known ones by Alain Aspect, 1981-2, it is only after the subtraction of ``accidentals'' from the coincidence counts that we get violations of Bell tests. The data adjustment, producing increases of up to 60% in the test statistics, has never been adequately justified. Few published experiments give sufficient information for the reader to make a fair assessment. There is a straightforward and well known realist model that fits the unadjusted data very well. In this paper, the logic of this realist model and the reasoning used by experimenters in justification of the data adjustment are discussed. It is concluded that the evidence from all Bell experiments is in urgent need of re-assessment, in the light of all the known ``loopholes''. Invalid Bell tests have frequently been used, neglecting an improved one derived by Clauser and Horne in 1974. ``Local causal'' explanations for the observations have been wrongfully neglected.

    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

    non completamente risolto per talune condizioni patologiche, nelle quali i dati obiettivi ed anamnestici sono relativamente uniformi e il quadro radiologico privo di qualsiasi caratteristica. Materiale e metodi: Il materiale � costituito da sei casi di istiocitosi delle cellule di Langherans della mandibola osservati nell'arco di un decennio. Lo studio � basato sulla valutazione della documentazione radiologica tradizionale. Le radiografie sono state eseguite in proiezione latero-laterale-obliqua che, come noto, libera quasi completamente la porzione orizzontale della mandibola dalla sovrapposizione delle immagini di altre strutture ossee. Risultati: I risultati delle indagini radiologiche sono riportati nella tabella I. Si tratta di reticoloendoteliopatie capaci di dar luogo ad un processo granulomatoso costituito da polinucleati eosinofili, plasmacellule e linfociti e, fondamentalmente, da grandi cellule istiocitarie mononucleate dotate di attivit� granulopessica e fagocitaria, spiccatamente proliferanti nel tessuto osseo, identificabili con le cellule di Langherhans della pelle, delle mucose, degli spazi periodontali, del midollo osseo. Il tessuto granulomatoso che ne deriva si infiltra tra gli elementi costitutivi dell'organo colpito ed estendendosi comprime, atrofizza e tende a distruggere il tessuto, sostituendosi ad esso. Le alterazioni determinate dal granuloma isiocitario di Langherhans prevalgono nettamente nel sistema scheletrico e si verificano, in ordine di frequenza, nel cranio, nelle ossa lunghe dell'estremit�, nel piede, nelle coste e nella colonna vertebrale. L'interessamento della mucosa orale � eccezionale. Conclusioni: Nel granuloma istiocitario unifocale di Langherhans della mandibola l'indagine radiologica � indispensabile per l'approccio allo studio della tumefazione premandibolare fermo restando che la diagnosi di natura si basa esclusivamente sulla biopsia.

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

    International Nuclear Information System (INIS)

    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

    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

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.

    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.

    Full Text Available Background and Objective: laboratory personnel have always accidental exposure to clinical samples, which can cause the transmission of infection. This threat can be prevented and controlled by education for the use of safety instruments. The purpose was to determine the frequency of accidental exposure to laboratory samples among Yazd laboratory personnel in 2011. Material and Methods: This descriptive cross-sectional study was conducted on 100 of Yazd clinical laboratory personnel. The data was collected, using a valid and reliable questioner, via interview and analyzed by means of SPSS software. Results: Eighty-six percent of the subjects reported an experience of accidental exposure to clinical samples, such as blood, serum and urine. The causes were carelessness (41% and work overload (29%. Needle- stick was the most prevalent injury (52% particularly in sampler workers (51% and in their hands (69%. There wasn’t significant relationship between accidental exposure to laboratory samples and the variables such as private and governmental laboratories (p=0.517, kind of employment (p=0.411, record of services (p=0.439 and academic degree (p=0.454. The subjects aged 20-29 (p=0.034 and worked in sampling unit had the highest accidental exposure. Conclusion: based on the results, inexperience of the personnel especially in sampling room, overload at work and ignorance of applying safety instruments are known as the most important reasons for accidental exposure to clinical samples.

    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)

    Full Text Available The paper describes a fatal case of accidental ingestion of a mixture of hydrochloric acid and hydrofluoric acid. The man was admitted to hospital, where appropriate treatment, adequate to his condition, was instituted. Numerous ventricular fibrillation episodes, for which the patient was defibrillated repeatedly, were observed during the period of hospitalization. The patient was in a critical condition, with progressive symptoms of hypovolemic shock and multiorgan failure. On the next day after admission, signs of electromechanical dissociation progressing to asystole were noted. The instituted resuscitation procedure proved ineffective and the patient died. Autopsy revealed brownish discoloration of the esophageal, gastric, and small intestinal mucous membranes. Numerous ulcerations without signs of perforation were found both in the esophagus and in the stomach. The mucous membrane of the small intestine demonstrated focal rubefactions, whereas no focal lesions of the large intestinal mucosa were seen. Microscopic investigation of the biopsy specimens collected from the stomach, duodenum and small intestine revealed mucous membrane necrosis foci, reaching the deeper layers of the wall of these organs. The mucous membrane of the large intestine was congested. Bioptates obtained from the lungs indicated the presence of hemorrhagic infarcts and focal extravasations. Poisoning with the aforementioned acids with consequent necrosis of the esophageal, gastric, duodenal and small intestinal walls with hemorrhages to the gastrointestinal tract, as well as extravasations and hemorrhagic infarcts in the lungs was considered to be the cause of death.

    Among the possible scenarios of accidental releases of chlorine from high pressure cylinders, this paper considers a typical one for the analysis. The calculated transient mass flow rate of chlorine released from a one-tonne cylinder showed that such an accident takes about 10 minutes to evacuate the cylinder. However, the toxic effect in the surrounding atmosphere continues for a longer period (about 20 minutes). The size and location of the toxic cloud at ground level were predicted as functions of time using an EPA-based dispersion model. The results showed a growth of the toxic cloud for some time beyond which it started to decay. For the typical scenario considered in this study, the most dangerous situation generated a toxic cloud with dimensions of 4000 m and 600 m in the downwind and crosswind directions, respectively. A study of the effects of some meteorological parameters on the size and location of the toxic cloud at ground level was also conducted. In general, it was observed that enhancing atmospheric mixing produced larger toxic zones during the early stages of the release and caused an opposite effect during the later ones. This dynamic data was linked to a GIS environment and the time variant was represented using an animation technique for Al-Ain City, United Arab Emirates. Data base information related to physical urban characteristics and population was immediately obtained for the affected areas.

    Full Text Available El objetivo de este trabajo es analizar los diferentes aspectos de la práctica de amputaciones durante el período victoriano de Inglaterra tales como: las causas que llevaron a tal práctica, los métodos y técnicas quirúrgicos usados durante el S. XIX así como la evidencia de atrofia y/o asimetría por causa del desuso. Tres casos de amputaciones fueron encontrados en una población industrial en el cementerio Victoriano de St. Pete s Collegiate Church en Wolverhampton (West Midlands, Inglaterra. Las amputaciones fueron realizadas en el miembro superior de una mujer (HB53 y los miembros inferiores de dos hombres (HB86 y (HB129. Se concluye que en los tres casos los individuos sobrevivieron a las amputaciones y que estas fueron realizadas mucho tiempo antes de la muerte. Dos de ellas fueron probablemente realizadas mediante cirugía (HB86 y HB129 mientras que la tercera (HB53 podría ser el resultado de un accidente industrial.

    Accidental blood exposure (ABE) exposes healthcare workers, including medical residents, to the risk of occupational infection. We aimed to determine the characteristics of ABEs in residents with an anonymous self-reporting electronic questionnaire. A total of 350 residents (33% from surgical disciplines) entered this survey. One hundred and eighty-five residents (52%) reported at least one ABE during their residency (median, 2; range, 1-25), 53% of which occurred in operating theatres. Sixty-nine per cent of residents followed the current procedures for local disinfection. ABEs were notified to the hospital administration by 62% of residents, but only 51% of residents were referred to the occupational medicine department. The most frequently reported concerns following ABEs were human immunodeficiency virus (52%) and hepatitis C virus infection (39%). In 74% of cases, the serological status of the index patient was investigated. Only 54% of residents were aware of their hepatitis B surface antibody titres. Medical residents behaved inappropriately in 33% of cases in this survey. Further educational programmes should include residents, and not only senior healthcare workers, in order to improve individual behaviours.

    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.

    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.

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

    International Nuclear Information System (INIS)

    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.)

    Lead (Pb) exposure in dairy cattle is associated with economic losses due to mortality and treatment costs, but with production animals there is also risk to the human food chain. The first objective of this study was to quantify the Pb concentration in milk from Pb-exposed cattle. The second objective was to correlate blood and milk Pb concentrations from individual cows. The third objective was long-term monitoring to determine the duration of milk contamination after exposure ceased. A dairy herd of more than 100 cows was accidentally exposed to Pb-contaminated feed. Milk and blood were collected for Pb analysis. Serial collection of milk samples continued for 2.5 years. The initial concentration of Pb in bulk tank milk was 0.0999 mg l⁻¹. The highest milk Pb concentration from an individual cow was 0.4657 mg l⁻¹ and the highest blood Pb concentration was 1.216 mg l⁻¹. One milk sample collected at the end of the study (day 922) contained 0.0117 mg Pb l⁻¹ of Pb. The calculated relationship between milk (y) and blood (x) Pb concentration was ln(y) = 3.4(x) - 2.21 (R² = 0.98).

  5. Accidental Cutaneous Burns Secondary to Salbutamol Metered Dose Inhaler

    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.

    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

    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.

    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 ...

    Full Text Available Abstract Introduction Epinephrine autoinjector devices are used with increasing frequency to treat severe anaphylactic reactions. Accidental injection, usually involving a finger, is a potential complication. Case presentation A physician in a Family Practice training program accidentally injected epinephrine into his left thumb while reading the operating instructions of an autoinjector (Epipen®. He developed swelling, pallor, and pain in the thumb. Treatment included topical nitroglycerin, oral vasodilators and warming of the thumb. As expected, none caused an immediate response; however, after 8 hours, the thumb was pink and warm. There was full recovery 2 months after the accident. We reviewed the treatment of accidental epinephrine injection, and found that the use of parenteral adrenergic alpha blocker phentolamine would have produced immediate recovery. Conclusions All health professionals concerned with the use of epinephrine autoinjectors should receive adequate instruction on their use. A regimen for management of accidental epinephrine injection, in particular the use of phentolamine, should be emphasized.

    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.

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.

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.

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

    International Nuclear Information System (INIS)

    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

    Full Text Available The purpose of this study was to examine county and state-level accidental poisoning mortality trends in Pennsylvania from 1979 to 2014.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.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.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.

No debemos olvidar el asesoramiento realizado al paciente, a la familia y/ o cuidadores sobre el manejo de la persona que ha sufrido un ictus, la adaptación del entorno y la prescripción, uso y manejo de ayudas técnicas cuando sea necesario.Las propuestas terapéuticas que expondré a continuación, no son recetas únicas que se puedan emplear del mismo modo en todos las personas que hayan sufrido un ictus. Con cada paciente será necesario una evaluación individualizada de su situación y una adaptación de la terapia según sus déficit específicos.La meta final de la Terapia Ocupacional es la integración óptima del paciente dentro de su entorno familiar y social, con el mayor grado de autonomía posible.ABSTRACTAmong the patients who need Occupational Therapy’s rehabilitation treatment, there are those who have suffered a cerebrovascular damage when elderly.People’s gradual ageing is one of the risk factors in the nervous central system’s alterations and this is why I am going to write about intervention on geriatric population.The Occupational Therapy’s rehabilitation treatment works on the functional, motor, sensorial, perceptive and cognitive areas. Moreover, we should not forget to advise the patient and his/her family or caregivers about the way of treating ,the environment’s adaptation, the prescription and use of technical aids when needed.The following therapeutic

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

    International Nuclear Information System (INIS)

    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.

    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.

    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.

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

    International Nuclear Information System (INIS)

    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)

    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

    Full Text Available Background: Successful extraction of third molars depends on preoperative diagnosis and planning. Gold standard preoperative examinations are performed through computed tomography, decreasing risks and avoiding potential accidents. The present report highlights the value of preoperative examinations in face of accidentally displaced third molars. Methods: An 18-years-old female patient underwent a third mandibular molar extraction with a general dentist. Accidentally, the mandibular left third molar was displaced into the sublingual space, making necessary a second surgical step. The surgery was interrupted and the patient was referred to an expert in maxillofacial surgery. Results: After 21 days awaiting an asymptomatic health status, the second surgical step was successfully performed using multislice computed tomography as preoperative imaging guide. Conclusions: The present case report highlights the clinical usefulness of imaging planning and informed consents in face of legal and ethic potential complaints.

This paper discussed the model of Marine Oil Spill Risk Mapping (MOSRM), which was constructed as follows: (1) proposing a marine oil spill risk system based on the typical marine oil spill pollution accidents and prevailing risk theories; (2) identifying suitable indexes that are supported by quantitative sub-indexes; (3) constructing the risk measuring models according to the actual interactions between the factors in the risk system; and (4) assessing marine oil spill risk on coastal city scale with GIS to map the overall risk. The case study of accidental marine oil spill pollution in the coastal area of Dalian, China was used to demonstrate the effectiveness of the model. The coastal areas of Dalian were divided into three zones with risk degrees of high, medium, and low. And detailed countermeasures were proposed for specific risk zones.

    The field of non-accidental injury (NAI) has been the subject of a number of theories and hypotheses of variable merit. Concerning injuries that occur within the intracranial compartment, much research has been undertaken to investigate the cause of SDH and parenchymal brain injury. Much, however, remains contentious, particularly regarding the medicolegal aspects of suspected child abuse. Issues that present the greatest challenges will be addressed. (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.

    2014-01-01

    Full Text Available The purpose of this paper is to report a salvage maneuver for accidental coverage of both renal arteries during endovascular aneurysm repair (EVAR of an infrarenal abdominal aortic aneurysm (AAA. A 72-year-old female with a 6 cm infrarenal abdominal aortic aneurysm was treated by endovascular means with a standard bifurcated graft. Upon completing an angiogram, both renal arteries were found to be accidentally occluded. Through a left percutaneous brachial approach, the right renal artery was catheterized and a chimney stent was deployed; however this was not possible for the left renal artery. A retroperitoneal surgical approach was therefore carried out with a retrograde chimney stent implanted to restore blood flow. After three months, both renal arteries were patent and renal function was not different from the baseline. Both endovascular with percutaneous access via the brachial artery and open retroperitoneal approaches with retrograde catheterization are feasible rescue techniques to recanalize the accidentally occluded renal arteries during EVAR.

    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.)

  19. Investigation of post-accidental management conditions. Complete final report dated July 31, 2009

    After a presentation of the process which resulted in the setting up of an investigation aimed at testing recommendations for post-accidental management, this report indicates the objectives of this investigation: to study the application of recommendations made by the CODIR-PA (Management Committee - Post-Accidental Management) to the operators of the milk sector, and to define an action plan to carry on and resume production. According to the adopted methodology, the study comprised two phases. The first one comprised an analysis of applications in the milk sector, the study of operational consequences on a zoning proposed by the CORDI-PA on the milk sector and on milk products, and the study of the acceptability and feasibility of considered options. The second phase addressed the elaboration of an action plan to carry on and resume the activity. While identifying and assessing the various risks, it identified critical issues for carrying on or resuming milk production in a contaminated territory, and defined an action plan to implement by anticipation or in the post-accidental situation

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

    International Nuclear Information System (INIS)

    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.

    Accidental hanging is uncommon. An immobile/fixed and exposed suspension apparatus is seen in almost all cases of hanging. A 50-year-old man, who was drunk, was trying to steal an iron rod by hiding it under his clothing. To secure hiding, he attached it to his body by a loose ligature around the neck, the waist belt of the sarong, and another band around the waist and by his underwear. Sometime later, because of ethanol intoxication, he fell asleep in the sitting position. While he was sitting on the floor, the iron rod was lifted up accidentally, and its upper end was wedged against the wall behind the victim, and the lower end was fixed against the floor. When he fell asleep, the weight of the tilted head acted as the constricting force compressing the neck by the ligature that was used to attach the iron rod to the neck. The cause of death was concluded as hanging in a man with ethanol intoxication. This case highlights a novel mobile suspension apparatus partially hidden inside the clothes, in a case of accidental hanging. A similar case has not been reported in the forensic literature.

    Brazil is signatory of international protocols related to the visit of nuclear-powered vessels, aircraft carriers and submarines to Brazilian ports. The submarines, during their stay in Brazilian ports, inform that there is no release of radioactive material to the environment. However, the possibility of occurrence of accidents with environmental releases from PWR reactors is real. Between 1993 and 2003, 13 nuclear submarines visited Brazilian ports. This work aimed to evaluate the potential impact due to the visits of nuclear-powered ships and submarines to the port of the city of Rio de Janeiro, in relation to releases of radioactive materials to the environment, considering both routine releases and accidental situations. The models selected to perform the assessments took into account the scenarios to be simulated. Simple, but conservative methodologies were used for the evaluation of routine releases. For accidental releases, the dynamics of the materials dispersion into the environment were considered. The present study was mainly focalized on the initial phase of an accident. The doses for the crew of the Brazilian navy ships, for IRD teams performing environmental monitoring, and for the population around the Guanabara Bay, close to the points of anchorage, were assessed. The results indicated that, in normal operational conditions, no significant radiological impact due to the visit of nuclear submarines to the port of the city of Rio de Janeiro is expected, even considering the occurrence of small routine radionuclide releases. The analysis of accidental releases, however, indicated that the submarines should be located at a minimum distance of 2,5 km from inhabited areas in the coast of the Guanabara Bay. The need for environmental control and training of the teams involved in the attendance of the submarines, during the period of their visit, was also considered. The need for revising the procedures for the preoperational surveys to be performed at the

    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

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

    Full Text Available Antecedentes: España ha participado en la ISAF desde el inicio del despliegue militar en Afganistán. En este trabajo se estudian las evacuaciones médicas hasta el Hospital Central de la Defensa Gómez Ulla (HCDGU, Role 4, durante los años 2009-2012, y las causas de las muertes ocurridas en territorio afgano desde el comienzo de la misión en 2002 hasta final de 2012. Material y Método: Se identificaron las historias clínicas de los evacuados y se diferenciaron entre bajas "no de combate" y "de combate". Las primeras se agruparon según la CIE.9.MC y las segundas según el mecanismo lesivo. Se describió la topografía de las lesiones en los casos de los heridos por arma de fuego y se analizaron las lesiones de los heridos por artefactos explosivos improvisados (IEDs. Se estudiaron las causas de los fallecimientos y se distinguieron las producidas por accidentes, acciones hostiles y muerte natural. Resultados: Se evacuaron 139 bajas, "de combate" 10,80% y "no de combate" 89,20%. La media de evacuaciones al año fue de 2,66 por cada 100 individuos desplegados. Entre las bajas "no de combate" las principales causas fueron las lesiones traumatológicas n=41 (33,6%. Entre las bajas por acciones hostiles los agentes lesivos fueron las armas de fuego n=7 (46,67% y los IEDs n= 8 (53,33%. El número de fallecidos del contingente español en Afganistan desde el inicio de la misión hasta Diciembre de 2012 ha sido de 37 personas. De ellos, 15 (40,54% fueron por acciones hostiles y 22 (59,46% por accidentes o muerte natural. Conclusiones: Las bajas "no de combate" representan casi el 90 % de las evacuaciones. Entre las bajas "no de combate" las cusas principales son las lesiones traumatológicas, los trastornos mentales y las enfermedades musculoesqueléticas. Las lesiones ocasionadas por IEDs parecen relacionadas con los efectos terciarios de la explosión. Las lesiones por armas de fuego se localizan principalmente en las extremidades. Los días de

    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.

    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.

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

    International Nuclear Information System (INIS)

    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

    With the continued development of nuclear power plants, more and more super-large cooling towers are to be built in China and around the world. For the safe operation of nuclear power plants, research work has been done on the causes of collapse of cooling towers, collapse modes and the secondary disasters caused by the collapse of cooling towers. However, the collapse modes and the ground vibration induced by the collapse of cooling towers subjected to the accidental loads have not been fully understood. This paper has been focused on the modes and mechanisms behavior of the collapse of cooling towers subjected to accidental loads. Meanwhile, prediction of the ground vibration due to the collapse of the cooling towers has also been completed in a parallel project. Using dynamic finite element program LS-DYNA, a 3D finite element model for a super-large cooling tower was developed and the nonlinear material models were incorporated. In this paper, four types of accidental loads were considered to trigger the collapse or local failure of the tower, including vehicle collision, airplane impact, local explosion and missile attack. It was found that vehicle collision, missile attack and small TNT equivalent explosives (2 kg, 20 kg, 200 kg) might result in local failure of the cooling tower, however, the tower can still keep stable. On the other hand, large TNT equivalent explosives (2000 kg, 4500 kg) could cause severe damages in the inclined columns of the cooling tower, and lead to progressive collapse of the entire cooling tower. The two kinds of TNT equivalent explosives caused the same collapse mode while the collapsing duration was different. The airplane impacted at the throat of the cooling tower caused the local failure of shell structure of the tower, and then the progressive collapse of the cooling tower happened due to the gravitational action. The resulting collapse mode was different from that triggered by the local explosion.

    2011-01-01

    In this research I examine social ordering processes in Kakuma refugee camp in Kenya. I view the camp as an accidental city, by which I challenge the image of the camp as a temporary and artificial waiting space or a protracted refugee crisis per se. The reference to the city is both metaphorically and physically relevant. First, the metaphorical dimension of the city places refugees and their negotiation of space into the realm of the normal and the possible, contrary to prevailing notions o...

  16. Is Project Management Still an Accidental Profession? A Qualitative Study of Career Trajectory

    2015-02-01

    Full Text Available In this study, the authors used qualitative techniques to look for reoccurring themes related to 87 project managers’ responses to interview questions associated with entry into the field of project management and career progression. The study found that despite the efforts of higher education, professional associations, and their professional development and certifications, the project management remains a destination by accident. Professional project managers do not intend to be project managers but “fall into” the profession. This study provides a conceptual framework for project manager career trajectory that has implications for project management training and mentoring and contributes to the growing literature on the accidental profession.

    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.

    Balantidium coli is the only ciliated protozoan which is known to infect human and nonhuman primates. Route of infection is faecal-oral route. It is actively motile and causes mostly asymptomatic infections, or it may develop dysentery which is similar to that which is caused by Entamoeba histolytica. Here, we are describing a case of an accidental finding of B.coli in the urine of a patient who presented with acute renal failure, based on its characteristic morphology and motility which were seen on light microscopy. This is the third case of Urinary Balantidiosis which has been reported from India. PMID:24995185

    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.

    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

    The computer program UFOTRI can be used for assessing the impact of accidental released tritium in the two chemical forms tritiated water vapour and tritium gas. By applying UFOTRI to potential European sites for ITER, it could be demonstrated that the main goal, the nonevacuation criteria, is fulfilled for the present release limits. Contributions in international studies together with the re-evaluation of experimental data showed that the plant sub-model as well as the soil sub-model are areas for further improvement. (author)

    The accidental close exposure of over 200 adults and children to a caesium-137 (137Cs) source in Goiania, Brazil in 1987 produced significant short-term morbidity in about 50 patients, and four deaths within a few weeks. Some 57% of those maximally exposed to radiation, developed orofacial lesions, notably purpura, spontaneous bleeding, ulcers and/or acute candidiasis. These lesions were probably mainly the consequences of depression of bone marrow elements by the radionuclide. Though the oral lesions that may follow iatrogenic exposure to ionizing radiation are well recognized this appears to be the first report on the oral sequelae of a serious radiation accident.

    Accidental intra-arterial injection of drugs is a sporadic complication in i.v. drug addicts. A 22-year-old drug-abuser injected flunitrazepam tablets dissolved in tap water into her left femoral artery and presented with clinical signs of acute ischaemia of the left leg. Severe rhabdomyolysis developed within 5 hours after the injection. Selective arterial catheter angiography showed an acute occlusion of the posterior tibial artery. Combination therapy with i.a. urokinase, i.a. prostaglandines and i.v. anticoagulation resulted in re-opening of the obstructed distal artery and complete cessation of symptoms.

  9. Electron paramagnetic resonance technique for radiation dosimetry: emerging trends for laboratory and accidental dosimetry

    International Nuclear Information System (INIS)

    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)

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

    International Nuclear Information System (INIS)

    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

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

    International Nuclear Information System (INIS)

    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

    The recent expansion of biocontainment laboratory capacity in the United States has drawn attention to the possibility of occupational exposures to BSL-3 and -4 agents and has prompted a reassessment of medical management procedures and facilities to deal with these contingencies. A workshop hosted by the National Interagency Biodefense Campus was held in October 2007 and was attended by representatives of all existing and planned BSL-4 research facilities in the U.S. and Canada. This report summarizes important points of discussion and recommendations for future coordinated action, including guidelines for the engineering and operational controls appropriate for a hospital care and isolation unit. Recommendations pertained to initial management of exposures (ie, immediate treatment of penetrating injuries, reporting of exposures, initial evaluation, and triage). Isolation and medical care in a referral hospital (including minimum standards for isolation units), staff recruitment and training, and community outreach also were addressed. Workshop participants agreed that any unit designated for the isolation and treatment of laboratory employees accidentally infected with a BSL-3 or -4 pathogen should be designed to maximize the efficacy of patient care while minimizing the risk of transmission of infection. Further, participants concurred that there is no medically based rationale for building care and isolation units to standards approximating a BSL-4 laboratory. Instead, laboratory workers accidentally exposed to pathogens should be cared for in hospital isolation suites staffed by highly trained professionals following strict infection control procedures.

    Current offshore design codes enable the capacity of structural components to be determined, but the equations apply only to the undamaged state. The ability to assess the performance of such components containing damage has only recently been developed and is important in the re-assessment of structures. In particular knowledge of the performance of members which are dented or bowed as a result of accidental damage is important in establishing the capacity of structures in-service, when for example using pushover analyses. Much research has been taken on the capacity of dented and bowed members. This paper reviews this data and establishes a database using screening criteria. This data is then compared with theoretical predictions from recently developed draft ISO equations. These show that dents and bows can significantly reduce the performance of members. A survey of offshore damage resulting in repairs has shown that 30% of this damage is the result of accidental events such as ship impact and dropped objects. Most damage found to members was in the form of dents, bows and cracks, with member severance in a few cases. The implications of this information for reassessment and offshore inspections are considered.

    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

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

    International Nuclear Information System (INIS)

    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)

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

    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.

    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.

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

    International Nuclear Information System (INIS)

    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

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

    International Nuclear Information System (INIS)

    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.

    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 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

    The bioethical and juridical debate on the status of frozen embryos sometimes adds new issues arising from new scientific evidence or by accidental occurrences that bring to the attention of the scientific community the need for new practical solutions. Within this scenario, there have been, in recent years, episodes concerning the accidental thawing of embryos, which have been cryopreserved for transfer. Two Italian cases (the Milan and the Rome cases) are here reported: the Milan case involves a couple undergoing artificial insemination. Three eggs were collected for insemination and two of them had been fertilized. During the night of 8/9 May 2007 a short circuit occurred, resulting in an electricity blackout, which caused the loss of the embryos in culture, which should have been transferred to the woman's uterus on 9 May. The couple applied for damage compensation from the hospital following the loss of the embryos. The case went to Court and the result was a judgment issued by the Milan civil court, which recognized that the centre was to blame for irreparable damage to the embryos. The Rome case, involves two couples (A and B) affected by sterility who applied to an authorized public centre to undergo an ART program. Following the medical procedures, two of the embryos produced were transferred to the woman in couple A and five were frozen, whereas three embryos produced by couple B were transferred to the uterus of the woman and six eggs were cryopreserved in the centre. Two years after the procedure there was an electricity blackout, and the backup electricity generator failed to function, causing the loss of the gametes and the embryos cryopreserved in the centre. Legal proceedings begun by the couples to obtain compensation for damages are still underway. The above reported cases have significantly intensified the bioethical debate on the lawfulness of such practices and on the fate of the cryopreserved embryos, at the same time opening new frontiers in

    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

    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

    A study of veterinarians' perceptions, and experience, of non-accidental injury (NAI) to pets was undertaken using an anonymous questionnaire distributed to a random sample of 1000 small animal practitioners in the UK. NAI was acknowledged by 91.3 per cent (95 per cent confidence interval, 88.2 to 93.9 per cent) of the 404 respondents who returned questionnaires, of whom 48.3 per cent (95 per cent confidence interval, 43.4 to 53.1 per cent) had either suspected or seen NAI. Four hundred and forty-eight cases were documented, predominantly in dogs (243) and cats (182). Factors either raising suspicion, or facilitating recognition, of NAI included: implication of a particular person, features of the history, referral agency involvement, behaviour of the owner and/or the animal, nature of the injuries, and socioeconomic class of owners. Additionally, sexual abuse and suspected cases of Munchausen syndrome by proxy were recorded.

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

    International Nuclear Information System (INIS)

    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

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

    International Nuclear Information System (INIS)

    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.

    1987-01-01

    In the nursery of an Austrian hospital, five newborns accidentally received 10% natrium chloride solution by infusion or oral feeding. Because of wrong labelling by the hospital pharmacy the solution was taken for 10% glucose. In all five newborns, bradycardia, edemas, cyanosis and cramps occurred. In all cases, autopsy revealed a fatal haemorrhagic encephalopathy and more or less extended haemorrhages of the lungs, the kidneys and the liver. There was no suppurative pneumonia and no arteritis. The intracerebral bleedings, thromboses and necroses may be provoked by tissue shrinking caused by hypernatraemic dehydration. The cerebral lesions again cause hyperosmolarity leading to death in most cases. Peritoneal dialysis which may be life-saving in some cases, unfortunately has not been performed in the present cases.

    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)

    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?

    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.

    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.

    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...

    2006-01-01

    Full Text Available Multiple simultaneous intracerebral hemorrhages (ICH are uncommon. We report the case of an 80-year-old woman with previous diagnosis of normal pressure hydrocephalus and who was brought to our hospital with altered mental status and urinary incontinence. Medical history of hypertension, hematological disorders or severe head trauma was absent. Platelet count and coagulation profile were unremarkable. An initial head computed tomography (CT showed sulcal enlargement and ventricular dilatation, but no evidence of ICH. A tap test indicated as a guide to case selection for shunt surgery accidentally resulted in cerebrospinal fluid (CSF overdrainage. The patient presented sudden neurological deterioration, with sluggishly responsive pupils and generalized tonic-clonic seizures. A new head CT demonstrated multiple supra and infratentorial ICH. The patient became comatose and had a fatal course. Hence, CSF overdrainage may either cause or precipitate multiple simultaneous ICHs, affecting both the infratentorial and supratentorial regions.

    Sodium hypochlorite (NaOCl) is the most commonly used solution in root canal treatments, as it is a low-cost method that displays a very effective antimicrobial activity against microbiota of infected root canals. However, this solution can cause complications especially due to its cytotoxic features. When this solution is injected into the adjacent tissues, the patient usually experiences intense pain, and an urgent treatment should be implemented in order to prevent a long-term sequelae. This paper describes the clinical features of two patients that experienced an accidental extrusion of NaOCl after endodontic treatment of varying severity and with different treatments. Furthermore, it shows the long-term neurologic injuries that this type of accidents may cause and a treatment protocol for these situations will be suggested. Key words:Nerve damage, root canal irrigation, root canal treatment, sodium hypochlorite. PMID:24558554

    2011-01-01

    In this paper, we examine the ways that early adolescents talked, interacted, and made references to events in their individual and collective lives during photography-based focus groups about sexuality and relationships. Twenty-three participants (10 boys and 13 girls) were recruited from three urban schools participating in a comprehensive sex education impact evaluation in the Northeast. We analyzed conversational narratives that were elicited in a group process while sharing photos of important people, contexts, and situations, showcasing participants' exploration of sexuality and relationships. Our analysis revealed four main themes: (a) direct and indirect family communication about sexuality, (b) accidental and intentional Internet usage, (c) shared and contested peer knowledge, and (d) school as a direct and indirect learning context. Implications and future directions for practice, research, and policy are explored. PMID:22983141

    This report contains an assessment of the radiological impact on the Greater London population of postulated accidental releases from the Sizewell PWR. Three of the degraded core accident releases postulated by the CEGB are analysed. The consequences, conditional upon each release, are evaluated in terms of the health impact on the exposed population and the impact of countermeasures taken to limit the exposure. Consideration is given to the risk to the Greater London population as a whole and to individuals within it. The consequences are evaluated using the NRPB code MARC (Methodology for Assessing Radiological Consequences). The results presented in this report are all conditional upon the occurrence of each release. In assessing the significance of the results, due account must be taken of the frequency with which such releases may be predicted to occur.

    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.

    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.

    This paper presents the results of regional scale atmospheric dispersion simulation of accidental emission of radionuclides from the Fukushima Daiichi Reactor, Japan following the Tohoku earthquake and tsunami event on 11 March 2011. The objective was to study the temporal behaviour of plume trajectory, concentration, deposition and radiation dose pattern over an 80 km range around the reactor. The time-varying meteorological parameters during the release period were simulated with a multi-scale nested atmospheric model WRF ARW and the trajectory, plume dispersion were computed with Lagrangian Particle Dispersion models HYSPLIT, FLEXPART using the available information on accidental source term. The simulations indicated that the wind flow over Japan during the release period was driven by the large scale extra-tropical westerly waves and associated low pressure systems. In the lower levels, the flow was influenced by the local topography/sea breeze causing occasional landward wind shift on the east coast of Japan. Simulated airflow trajectories revealed that the plume stayed over the ocean by westerly winds on most days and the radioactivity dispersed over sea surface. Landward trajectories were found on a few days due to southeasterly, easterly and northeasterly flow (15-17, 19-21 March 2011) during which much of the radionuclides deposited over the land region. The hotspot of depositions occurred over east Pacific Ocean near to Japan. Over the land relatively high depositions were simulated in a narrow zone of 20 km width and 80 km length in the northwest sector in agreement with monitor data. Simulations showed wet depositions over the land to be higher than the dry depositions during 12-30 March due to occurrence of rainfall on some days. Comparison of activity deposition and air dose values with available observations confirmed that the plume pattern in a finer length scale around the site could be simulated realistically and agree with the measurements

    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

    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.

    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.

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

    International Nuclear Information System (INIS)

    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

    2014-10-01

    Full Text Available BACKGROUND AND OBJECTIVES: In patients with burn injury drug pharmacology will be altered and this poses special anaesthetic challenge when an subcutaneous injection of a non- depolarizing muscle relaxant occurs in such a patient. Small studies remain an important source of knowledge and hence this study aims to provide information on the anaesthetic management in a case of accidental subcutaneous injection of vecuronium bromide in a burns patient. PRESENTATION, DIAGNOSIS & MANAGEMENT: A 22 year young male with 4 days old hot water induced grade 1 burns involving 45% of body surface area was posted for burns dressing. Anaesthesia was induced with propofol and vecuronium bromide through an external jugular vein to aid tracheal intubation. As the patient was not anaesthetized even after 10 minutes routine check lead to the discovery of fullness at the tip of the intravenous catheter indicating an extravasation of the drugs. Hence the other external jugular vein was cannulated and the patient induced and intubated using propofol, sevoflurane, nitrous oxide and oxygen. The action of vecuronium outlasted the duration of surgery. So the patient continued to receive support of mechanical ventilation with nitrous oxide and oxygen. It took 130 minutes for the clinical signs of recovery from the muscle relaxant to manifest. He was then reversed & extubated with subsequent good recovery. CONCLUSION: Subcutaneous injection of these drugs poses problems of delayed onset of action and prolonged duration of action. In an inadvertent accidental subcutaneous 0.1 mg/kg vecuronium bromide injection in a patient with 4 day old 45% burns showed delayed onset action and prolonged neuromuscular blockade due to subcutaneous deposition of the drug which was managed with mechanical ventilation .The reported resistance to the action of NDMR drugs in patient with burns was not noticed here probably because of the age of the thermal injury.

    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

    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.

    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.

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

    International Nuclear Information System (INIS)

    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

    Full Text Available Attention Deficit Hyperactivity Disorder (ADHD is a frequent neurodevelopmental disorder that increases accidental risk. Recent studies show that some patients with ADHD can also suffer from excessive daytime sleepiness but there are no data assessing the role of sleepiness in road safety in patients with ADHD. We conducted an epidemiological study to explore sleep complaints, inattention and driving risks among automobile drivers.From August to September 2014, 491186 regular highway users were invited to participate in an Internet survey on driving habits. 36140 drivers answered a questionnaire exploring driving risks, sleep complaints, sleepiness at the wheel, ADHD symptoms (Adult ADHD Self-Report Scale and distraction at the wheel. 1.7% of all drivers reported inattention-related driving accidents and 0.3% sleep-related driving accidents in the previous year. 1543 drivers (4.3% reported ADHD symptoms and were more likely to report accidents than drivers without ADHD symptoms (adjusted OR = 1.24, [1.03-1.51], p 15 versus 3.2% of drivers without ADHD symptoms and 20.5% reported severe sleepiness at the wheel versus 7.3%. Drivers with ADHD symptoms reported significantly more sleep-related (adjusted OR = 1.4, [1.21-1.60], p < .0001 and inattention-related (adjusted OR = 1.9, [1.71-2.14], p<0001 near misses than drivers without ADHD symptoms. The fraction of near-misses attributable to severe sleepiness at the wheel was 4.24% for drivers without ADHD symptoms versus 10,35% for drivers with ADHD symptoms.Our study shows that drivers with ADHD symptoms have more accidents and a higher level of sleepiness at the wheel than drivers without ADHD symptoms. Drivers with ADHD symptoms report more sleep-related and inattention-related near misses, thus confirming the clinical importance of exploring both attentional deficits and sleepiness at the wheel in these drivers. Road safety campaigns should be improved to better inform drivers of these accidental

    To identify maternal and infant characteristics associated with accidental suffocation and strangulation in bed (ASSB) in US infants. Using 2000-2002 US linked infant birth and death certificate cohort files, we compared ASSB deaths to survivors. Adjusted odds ratios (aOR) from logistic regression were used to analyze associations between selected maternal and infant characteristics and ASSB mortality. During 2000-2002, 1,064 infants died from ASSB, resulting in an ASSB mortality rate of 9.2 per 100,000 live births. Most ASSB deaths (71%) occurred before an infant reached 4 months old. Maternal factors associated with an increased risk of ASSB were younger age (using maternal age of 25-29 years as reference aOR 2.6 for mothers mortality risk. Younger, less educated, mulitparous, non-Hispanic black or American Indian women and their families who smoke during their pregnancy and deliver male or preterm infants, may need more intense safe sleeping education during the infant's first year of life, especially during the first 4 months of age.

  14. Modeling accidental releases to the atmosphere of a dense reactive chemical (Uranium hexafluoride)

    Science.gov (United States)

    Hanna, Steven R.; Chang, Joseph C.; Zhang, Xiaoming J.

    In order to model the atmospheric transport and dispersion of dense reactive chemicals such as uranium hexafluoride (UF 6), it is necessary to include algorithms that account for heat exchanges due to chemical reactions and phase changes. UF 6 may be released accidentally at uranium-enrichment plants as a warm gas from a pipeline rupture, or as a flashing liquid from a pressurized tank or line break. The resulting plume is initially very dense due to the large molecular weight of UF 6, but may become lighter-than-air as the UF 6 reacts with water vapor to form HF, which has a molecular weight less than that of air, and which may cause an increase in plume temperature due to the exothermic reaction. The major chemical and thermodynamic processes related to UF 6 have been incorporated in a modified version of an existing dense gas model, HGSYSTEM. The same general approach could be used to include other reactive chemicals in the modeling system. New modules that are applicable to any type of chemical release have also been added to HGSYSTEM to account for building downwash, lift-off of warm plumes from the ground, and deposition. The revised HGSYSTEM/UF 6 model has been evaluated with field data from UF 6 tests. The sensitivities of the model predictions to variations in input parameters have been assessed.

    Non-accidental head injury (NAHI) is a major cause of neurological disability and death during infancy. Radiological imaging plays a crucial role in evaluating craniospinal injury, both for guiding medical management and the forensic aspects of abusive trauma. The damage sustained is varied, complex and may be accompanied by an evolving pattern of brain injury secondary to a cascade of metabolic and physiological derangements. Regrettably, many cases are poorly or incompletely evaluated leading to diagnostic errors and difficulties in executing subsequent child care or criminal proceedings. It is evident, from cases referred to the authors, that imaging protocols for NAHI are lacking (or only loosely adhered to, if present) in many centres throughout the U.K. Future research in this field will also be hampered if there is a lack of consistent and reliable radiological data. There is no nationally agreed protocol for imaging NAHI. We propose such a protocol, based upon a wide experience in the medical management of child abuse and extensive involvement in the medicolegal aspects of NAHI. Jaspan, T., et al. (2003).

  17. Preliminary investigations of the significance of the ingestion pathway following accidental releases with actinides

    International Nuclear Information System (INIS)

    Preliminary accident consequence assessments have been performed with the computer code UFOMOD to study the significance of the ingestion pathway in accidental releases with actinides. The investigation was based on the release category K1 of the 'Risk Oriented Analysis of the SNR 300', in which a higher fraction of actinides is released than in the worst release category for an LWR. The analysis was carried out using the currently implemented food chain transport model WASH-1400/BSU and data from the dynamic model from the MARC methodology. To study the influence of the time of the accident on the food chain-related results, releases in January and July were considered by means of the MARC data. In this report the differences are presented between both food chain transport models for transuranium elements and those which are observed in the potential doses due to ingestion, the areas affected by food-bans and the late health effects when using both models and taking the influence of the season into account.

  18. Metabolic transit of radiocaesium in domestic animals - practical application in an accidental situation

    International Nuclear Information System (INIS)

    When a serious nuclear accident occurs, the radioisotopes of caesium are very worrying to public health. Because of their long environmental persistence, their diffusion and their solubility in natural environments, they are present in many foodstuffs. Numerous studies were undertaken during the atmospheric nuclear tests, but since the accident of Tchernobyl land Goiania, this research has been pursued anew. By using the experimental data,, this report takes stock of the knowledge on the metabolic transit of radiocaesium in domestic animals. The transfer of this radionuclide in the major foodstuffs of animal origin (milk, meat, eggs) is important and depends on the metabolism of the animal species, and in one species, the age, the physiologic state and the diet. Nevertheless, it is possible to restrict the radioactive contamination by adding to all animal feed, some additives. The methods for in vivo determination of the radioactive measurements in cattle, in laboratory or in real conditions, are discussed too. Finally, all these results are used to consider the short-, middle- and long-term management of an accidental situation. (authors)

    Children are at increased risk for various causes of injury from accidents. Accidents are, by far, the leading cause of death among children and adolescents. The aim of this study is to evaluate the lethal childhood accidents in İstanbul by age groups. Reports of autopsies performed between 2001 and 2005 in the Morgue Department of the Council of Forensic. Medicine in Istanbul (n :16853) are examined retrospectively. 833 deaths from accidents in children aged 0-18 years are investigated into the study. The parameters of age, gender, types of accidents and causes of death are evaluated. The accidents account for 47.3% of the deaths among children aged 0-18 years. Of 833 cases, 601 (73%) are male and 232 (27%) are female. The female to male ratio is 1/2.6. The highest rate of death from accidents is at the group of 15-18 years. The primary causes of accidental childhood deaths are motor vehicle accidents (23.1%), followed by drowning (20,1%), poisoning (15.7%), and fall from height (15.5%). The incidence and types of trauma vary with socio-economic status and culture. İstanbul, where this study is conducted in, has approximately 3000 autopsy number annually. Therefore, it provides an important database.

    Over the past half century, a surprising number of major pollution incidents occurred due to tailings dam failures. Most previous studies of such incidents comprised forensic analyses of environmental impacts after a tailings dam failure, with few considering the combined pollution risk before incidents occur at a watershed-scale. We therefore propose Watershed-scale Tailings-pond Pollution Risk Analysis (WTPRA), designed for multiple mine tailings ponds, stemming from previous watershed-scale accidental pollution risk assessments. Transferred and combined risk is embedded using risk rankings of multiple routes of the "source-pathway-target" in the WTPRA. The previous approach is modified using multi-criteria analysis, dam failure models, and instantaneous water quality models, which are modified for application to multiple tailings ponds. The study area covers the basin of Gutanting Reservoir (the largest backup drinking water source for Beijing) in Zhangjiakou City, where many mine tailings ponds are located. The resultant map shows that risk is higher downstream of Gutanting Reservoir and in its two tributary basins (i.e., Qingshui River and Longyang River). Conversely, risk is lower in the midstream and upstream reaches. The analysis also indicates that the most hazardous mine tailings ponds are located in Chongli and Xuanhua, and that Guanting Reservoir is the most vulnerable receptor. Sensitivity and uncertainty analyses are performed to validate the robustness of the WTPRA method. PMID:26633450

  3. UFOING: A program for assessing the off-site consequences from ingestion of accidentally released radionuclides

    International Nuclear Information System (INIS)

    The program UFOING estimates foodchain-related consequences following accidental releases of radionuclides to the atmosphere. It was developed as a stand-alone supplement to the accident consequence assessment program system UFOMOD to allow faster and more detailed investigations of the consequences arising from the foodchain pathways than possible with the version of UFOING which is implemented in UFOMOD. For assumed releases at different times of the year, age dependent individual doses, collective doses, individual risks for fatal stochastic somatic health effects as a function of time, the total numbers of the effects, and the areas affected by foodbans together with the estimated duration of the bans are calculated. In addition, percentage contributions of radionuclides and foodstuffs to the doses and risks can be evaluated. In the first part of this report, an overview over the program is given. The other parts contain a user's guide, a program guide, and descriptions of the data employed and of the version of UFOING which is implemented in UFOMOD. (orig.)

  4. Thermoluminescence properties of irradiated commercial color pencils for accidental retrospective dosimetry

    International Nuclear Information System (INIS)

    Color pencils are widely used mostly in kindergartens, in schools and could be found in all houses with families having young children. Their wide spread use in modern times as well as their chemical composition, consisting mostly of Si and Al, constitute two strong motivations towards exploiting their use as accidental retrospective thermoluminescent dosimeters. The present manuscript reports on the study of colored pencils manufactured by a commercial brand in China which is very common throughout Turkey. The preliminary results discussed in the present work illustrated encouraging characteristics, such as the presence of a trapping level giving rise to natural TL in a temperature range that is sufficiently high. Specific thermoluminescence features of this peak, such as glow peak shape and analysis, anomalous fading, thermal quenching, reproducibility, linearity and recovery ability to low attributed doses were studied. The results suggest that the color pencils could be effectively used in the framework of retrospective thermoluminescent dosimetry with extreme caution, based on multiple aliquot protocols. - Highlights: • Thermoluminescence of the inner part of commercial colored pencils was studied. • The presence of a trapping level giving rise to natural TL at 260 °C was yielded. • Deco analysis, anomalous fading, thermal quenching, reproducibility, linearity and recovery ability of this peak were studied

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

    International Nuclear Information System (INIS)

    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. - Highlights: • Application of acids mixture for more effective glass samples etching. • Bleaching can be performed not only by blue but also by UV light. • The readout with BG39 optical filter improves the TL signal intensity. • The glass samples from touch mobile phones are worse emergency TL dosimeters

    This report updates, for 1980 through 1982, the results of continuing medical surveillance of a Marshallese population accidentally exposed to radioactive fallout in March 1954. The originally exposed Marshallese population comprised 64 persons on Rongelap Atoll who each received, on the average, an estimated 190 rads of absorbed external gamma radiation, 18 on Ailingnae Atoll who received 110 rads, and 159 on Utirik who received 11 rads. There were, in addition, 3 persons in utero on Rongelap, 1 person in utero on Ailingnae, and 8 persons in utero on Utirik who are considered exposed. The recipients of primary medical care include exposed and comparison populations as well as a rather large number of additional beneficiaries who are seen on a humanitarian basis of practical need and resource availability. In recent years, about 1400 people have been seen annually. This report, however, deals with four clearly defined groups: the remaining individuals who were exposed to radioactive fallout on Rongelap, Ailingnae, and Utirik in 1954 (including those in utero), and a comparison population of individuals from Rongelap who were unexposed. The number of persons now in each exposure category are 51, 12, 116, and 137, respectively. 100 references, 4 figures, 5 tables. (ACR)

    Full Text Available OBJECTIVE Analyzing profiles of intoxication and accidental poisoning of infant-juvenile population (0-24 years in the household, treated at a reference facility for Emergency and Primary Care, during the year 2013. METHOD A descriptive, cross-sectional study. Data were analyzed using Epi-Info, by way of simple and bivariate analyzes. The project was approved by the Research Ethics Committee (protocol 405.578. RESULTS There were 45 intoxications, with a prevalence of males (60.0%, aged 1-4 years (71.1%. Among children under one, there was a higher frequency of pesticide poisoning (66.6%, between the ages of 1-4 by cleaning products (34.4%, and between 5-9 years of age by pharmacological substances (66.6%. The primary assistance was provided only at health institutions, with hospital admissions in 24.4% of the cases. CONCLUSION The importance of prevention through legislation is evident, in order to ensure greater safety in packaging of various products, and community awareness to eliminate risks in the household environment.

    In this paper we described an experimental study on the first aid for the accidental intake of radionuclides. Following experiments on first aid were made: (1) Sodium Alginate or prussian blue was respectively given orally to the mice immediately after administration of /sup 85/Sr or /sup 134/Cs. (2) Isotonic saline intraperitoneal treatment as a type of water supply or DTPA oral treatment was made to the mice immediately after intravenous injection of /sup 58/Co or /sup 54/Mn. The whole body retention in mice was measured with a 5 cm NaI(Tl) scintillation detector up to 28 hr after administration. Sodium alginate or prussian blue reduced intestinal absorption of radiostrontium or radiocesium. DTPA and isotonic saline increased excretion of radiocobalt and radiomanganese in urine. DTPA oral treatment reduced the whole body retention of /sup 58/Co to 66% and /sup 54/Mn to 89% of the control. It was worked out from the dose estimation that the intraperitoneal injection of 10 ml isotonic saline or DTPA oral administration immediately after /sup 58/Co injection decreased the internal radiation dose by approximately 22% or 14%, respectively.

  9. Protective action guides for accidentally contaminated water and food. Proceedings of a workshop

    International Nuclear Information System (INIS)

    The Workshop on Protective Action Guides for Accidentally Contaminated Water and Food was designed for those who have experience in planning for and responding to ingestion exposure scenarios. The objective was to identify and discuss all of the issues, problems, relevant experiences, and research that should be considered in the development of Protective Action Guides (PAGs) for water and food. The workshop proved to be very helpful for those responsible for developing PAGs for the ingestion exposure pathways. This workshop addressed the roles and responsibilities for the development of PAGs. EPA has the responsibility for development of PAGs, except in the case of PAGs for food for which the responsibility is shared with FDA. EPA participated in the development of the recommendations on PAGs for food and animal feed that FDA published in 1982, which are under revision. In the absence of PAGs specifically for water, past practice has been for EPA to provide ad hoc guidance when needed. EPA will be developing guidance for drinking water during the next fiscal year and, therefore, one of the working groups at the workshop was devoted to considering issues related to PAGs for water. It has not yet been determined whether PAGs for drinking water should be separate or included with those for food. These issues were discussed at the workshop and the recommendations included in this proceedings document will be used as resource in the development of PAGs for the ingestion pathway

  10. Medical status of Marshallese accidentally exposed to 1954 Bravo fallout radiation: January 1980-December 1982

    International Nuclear Information System (INIS)

    This report updates, for 1980 through 1982, the results of continuing medical surveillance of a Marshallese population accidentally exposed to radioactive fallout in March 1954. The originally exposed Marshallese population comprised 64 persons on Rongelap Atoll who each received, on the average, an estimated 190 rads of absorbed external gamma radiation, 18 on Ailingnae Atoll who received 110 rads, and 159 on Utirik who received 11 rads. There were, in addition, 3 persons in utero on Rongelap, 1 person in utero on Ailingnae, and 8 persons in utero on Utirik who are considered exposed. The recipients of primary medical care include exposed and comparison populations as well as a rather large number of additional beneficiaries who are seen on a humanitarian basis of practical need and resource availability. In recent years, about 1400 people have been seen annually. This report, however, deals with four clearly defined groups: the remaining individuals who were exposed to radioactive fallout on Rongelap, Ailingnae, and Utirik in 1954 (including those in utero), and a comparison population of individuals from Rongelap who were unexposed. The number of persons now in each exposure category are 51, 12, 116, and 137, respectively. 100 references, 4 figures, 5 tables

    Full Text Available Among the mechanisms that influence herbivorous insects, fires, a very frequent historical phenomenon in the cerrado, appear to be an important modifying influence on lepidopteran communities. The purpose of this study was to compare the richness, abundance, frequency, and composition of species of caterpillars in two adjacent areas of cerrado sensu stricto, one recently burned and one unburned since 1994, on the experimental farm “Fazenda Água Limpa” (FAL (15∘55′S and 47∘55′W, DF, Brazil. Caterpillars were surveyed on two plant species, genus Erythroxylum: E. deciduum A. St.-Hil. and E. tortuosum Mart. (Erythroxylaceae. We inspected a total of 4,196 plants in both areas, and 972 caterpillars were found on 13.3% of these plants. The number of plants with caterpillars (frequency differed significantly between the areas. The results indicate that recent and accidental fires have a positive effect on the abundance of caterpillars up to one year postfire, increase the frequency of caterpillars associated with Erythroxylum species in the cerrado and do not affect the richness of caterpillars on these plants. Moreover, the fires change the species composition of caterpillars by promoting an increase in rare or opportunistic species.

    This paper reports register data on a consecutive series of 141 children and teenagers hospitalized due to firearm injuries during a 21-year period in a community with restrictive firearm laws. Most of the injuries were minor and hospitalization was short. Shot by an air gun resulting in an eye injury was the most frequent reason for hospitalization. The patients hospitalized due to firearm injuries were compared with a control group composed of 141 individuals matched pair-wise for sex and age. The total morbidity during the follow-up period of on average 10 years was higher among patients compared with controls concerning both somatic diseases and injuries. All cases of severe psychopathology were found in the patient group. Criminality was higher among patients compared with controls and the former were younger at the time of the first crime compared with the latter. This study indicates that, irrespective of firearm laws, young people suffering from firearm injuries, even if the injury is classified as accidental, run a higher risk of becoming psychosocially disadvantaged and criminal as adults. This makes preventative measures highly necessary not only from a societal point of view, but also to avoid individual suffering in this high-risk group of youngsters. PMID:9426991

    The April 7, 1962 criticality accident involving human exposures was the first to have occurred in any production facility at Hanford. The accidental nuclear excursion did not result in any mechanical damage or spread of contamination. Three employees received over-exposure to gamma and neutron radiation. None were fatally exposed and in each case the over-exposure was recognized promptly. Following an initial period of medical observation and testing, the men were released to work. They continued to be followed clinically. Clinical studies performed were hematological procedures including leukocyte chromosome aberrations, morphologically aberrant blood cells, bone marrow evaluations, blood chemistry determinations, amino acid excretion studies, seminal fluid, urinary gonadotropins and estrogen excretion studies, testicular biopsies and crystalline lens examinations. These studies, along with a brief description of the accident and of the dosimetry, are summarized in this report by those participating in the studies. In view of the dose ranges received in these cases, both the negative and positive findings are considered to be of unusual interest due to the lack of knowledge of effects following human exposures at these levels.

  14. Game theory of pre-emptive vaccination before bioterrorism or accidental release of smallpox.

    2015-06-01

    Smallpox was eradicated in the 1970s, but new outbreaks could be seeded by bioterrorism or accidental release. Substantial vaccine-induced morbidity and mortality make pre-emptive mass vaccination controversial, and if vaccination is voluntary, then there is a conflict between self- and group interests. This conflict can be framed as a tragedy of the commons, in which herd immunity plays the role of the commons, and free-riding (i.e. not vaccinating pre-emptively) is analogous to exploiting the commons. This game has been analysed previously for a particular post-outbreak vaccination scenario. We consider several post-outbreak vaccination scenarios and compare the expected increase in mortality that results from voluntary versus imposed vaccination. Below a threshold level of post-outbreak vaccination effort, expected mortality is independent of the level of response effort. A lag between an outbreak starting and a response being initiated increases the post-outbreak vaccination effort necessary to reduce mortality. For some post-outbreak vaccination scenarios, even modest response lags make it impractical to reduce mortality by increasing post-outbreak vaccination effort. In such situations, if decreasing the response lag is impossible, the only practical way to reduce mortality is to make the vaccine safer (greater post-outbreak vaccination effort leads only to fewer people vaccinating pre-emptively).

    Injuries caused by accidents or violent situations in pediatric patients are a serious social problem where prevention plays a key role. The aim of this study was to describe the epidemiological situation of pediatric injuries in Spain. A prospective study of pediatric patients receiving care in the Emergency Service of the Complejo Hospitalario de Navarra due to for reasons of accidental injury was conducted. The study covered a period of 1 year and assessed a total of 16 variables. There were a total of 8,876 patients, of whom 56.4% were males. Traumatic injuries such as fractures and craniocerebral trauma were identified as the most frequent injuries, occurring as a result of injuries mainly in the home. In females, there was a decrease in the incidence of injuries related to age. There was a greater incidence at the end of the day, during the weekend, and in the months of March to October. The epidemiological profile of pediatric patients who met with accidents in Navarra, Spain, is described. The knowledge of the main areas and factors related to injuries allows us to improve preventive measures, which would contribute to better control in this region of Spain. PMID:27414146

    Urine bioassay measurements for uranium and medical laboratory results were studied to determine whether there were any health effects from uranium intake among a group of 31 workers exposed to uranium hexafluoride (UF{sub 6}) and hydrolysis products following the accidental rupture of a 14-ton shipping cylinder in early 1986 at the Sequoyah Fuels Corporation uranium conversion facility in Gore, Oklahoma. Physiological indicators studied to detect kidney tissue damage included tests for urinary protein, casts and cells, blood, specific gravity, and urine pH, blood urea nitrogen, and blood creatinine. We concluded after reviewing two years of follow-up medical data that none of the 31 workers sustained any observable health effects from exposure to uranium. The early excretion of uranium in urine showed more rapid systemic uptake of uranium from the lung than is assumed using the International Commission on Radiological Protection (ICRP) Publication 30 and Publication 54 models. The urinary excretion data from these workers were used to develop an improved systemic recycling model for inhaled soluble uranium. We estimated initial intakes, clearance rates, kidney burdens, and resulting radiation doses to lungs, kidneys, and bone surfaces. 38 refs., 10 figs., 7 tabs.

    Full Text Available Objectives: Accidental hypothermia (AH is a potentially life-threatening condition that can lead to significant morbidity and life-long effects. Navy personnel are always at a greater risk of AH due to frequent outdoor work, wilderness exposure, prolonged immobility and exhaustion. The purpose of the survey was to assess Chinese Navy members’ awareness of AH and to make recommendations with regard to better measures for improving it. Methods: 111 Navy members completed a written questionnaire that was subsequently analyzed. Results: 30.6% of the respondents have experienced AH and 64.9% rated their knowledge of AH as “low” or “none”. Over half of them identified the initial symptom of AH as obvious shivering (69.4% and apathy (45.0%. As for the aggravate symptoms, 60.9% chose the wrong answer of more obvious shivering instead of the right one—absence of shivering (5.4%. In the case of the treatment of mild AH, more than half of the respondents chose the wrong answers. Conclusions: This study suggests that the basic skills of recognition and treatment of AH are inadequate in the Chinese Navy. Further work is required to develop a systematical, comprehensive and corresponding education method that would promote correct actions during AH.

  18. A critical reappraisal of nuclear power plant safety against accidental aircraft impact

    International Nuclear Information System (INIS)

    The overall problem of nuclear power plant safety against an accidental aircraft impact is discussed in relation with its structural analysis and design. Associated risks, such as fire, which is a potential source of damage for buildings and other structures, are not considered. The paper is divided in two parts. In part I different approaches used for determining the reaction-time curve are discussed. The influence on the results of target motions is examined next. It is shown that for the evaluation of structural response an aircraft-structure interaction analysis is usually an unnecessary refinement, 'mean' reaction-time and impact area-time curves being sufficient to define the excitation. Preliminary results for oblique impact are also given. Since the conditional probability of a normal impact is very small, the consideration of oblique impact may become acceptable in future design criteria. In part II, available solutions for the resulting structural dynamic problem are reviewed. The feasibility of resorting to a static analysis is also discussed. Present practices to evaluate floor response spectra are reviewed next. The short-comings of the 'deterministic' approach are pointed out. It is proposed to define the excitation as a mean plus a fluctuating force. The latter is treated as a nonstationary random process and the problem solved by numerical integration in the time domain. Although such solutions get prohibitively expensive when the number of degrees of freedom becomes large, results obtained for simple models may help to clarify which are the important variables of the problem.

    Full Text Available A 35-year-old female presented for laser in-situ keratomileusis (LASIK. Her preoperative eye exam was normal, with a preop refraction of OD -2.50 D Sph +1.25 D Cyl Χ175 and OS -2.75 D Sph +1.50 D Cyl Χ165 (cycloplegic and manifest, with 20/20 BCVA OU. The central pachymetry reading was 553 ΅m in the right eye. Preoperative topography was normal. At the start of the pendular microkeratome path, some resistance was felt, but the microkeratome continued along its path. Upon inspection of the flap, there was a central rectangle of intact epithelium with two mirror-image flaps on both sides. The flap was repositioned and LASIK was discontinued. The cornea healed with two faint thin linear vertical parallel scars at the edge of the pupil. Postoperative inspection of the blade revealed central blunting. One month postoperatively, the uncorrected visual acuity (UCVA was 20/20. Manifest and cycloplegic refractions were plano. This is an interesting case of accidental flap complication resulting in the correction of mild myopic astigmatism.

  1. Accidental cloning of a single-photon qubit in two-channel continuous-variable quantum teleportation

    International Nuclear Information System (INIS)

    The information encoded in the polarization of a single photon can be transferred to a remote location by two-channel continuous-variable quantum teleportation. However, the finite entanglement used in the teleportation causes random changes in photon number. If more than one photon appears in the output, the continuous-variable teleportation accidentally produces clones of the original input photon. In this paper, we derive the polarization statistics of the N-photon output components and show that they can be decomposed into an optimal cloning term and completely unpolarized noise. We find that the accidental cloning of the input photon is nearly optimal at experimentally feasible squeezing levels, indicating that the loss of polarization information is partially compensated by the availability of clones

  2. Clinical study of fetal liver transplantation in treatment of four cases of accidental or therapeutic acute radiation sickness

    International Nuclear Information System (INIS)

    This report summarized the clinical experience of fetal liver transplantation (FLT) in the medical handling of accidental (case 1) or therapeutic (cases 2-4) acute radiation sickness of severe haemopoietic form. In addition to receiving 80 mg/kg of cyclophosphamide, cases 2, 3 and 4 were exposed to total body single irradiation of 5.5, 5.0 and 5.0 Gy, respectively; while case 1 was exposed to whole body irradiation of 5.2 Gy only. The total number of nucleated fetal liver cells transplanted was 2.26-4.1 x 108/kg. Only 2-5% of peripheral blood cells of cases 2, 3 and 4 were found to have allogeneic marker. The author points out that FLT may be beneficial in those cases of accidental irradiation or patients with acute leukemia when there were no HLA-identical bone marrow donors available

  3. Radionuclide dispersion and hydrodynamics of Ilha Grande Bay (Angra dos Reis, RJ) simulated from hypothetical accidental releases of liquid wastes

    International Nuclear Information System (INIS)

    This study has the aim to assess the impact of accidental release of radionuclides postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models of hydrodynamic circulation and transport for the simulation of tritium dispersion caused by an accidental release in Ilha Grande Bay from the site of the future third plant in two circulation scenarios. The main difference between the scenarios is based on the enhancement of dilution of the highest concentrations in the last one. This dilution enhancement resulting in decreasing concentrations was observed only during the first two weeks, when they ranged from 1 x 109 to 5 x 105 Bq/m³ close to the Itaorna beach spreading just to Sandri Island. After 180 days, the plume could not be detected anymore in the bay, because their activities would be lower than the minimum detectable value (< 11 kBq/m³). (author)

    Acute exogenous lipoid pneumonia is an uncommon condition caused by aspiration of oil-based substances, occurring mainly in children. Here, we report the case of an 83-year-old patient with Alzheimer's disease who presented with coughing and hypoxia. The diagnosis of acute exogenous lipoid pneumonia caused by accidental kerosene ingestion was made on the basis of the patient's clinical history, and typical radiological and cytological findings. The patient's cognitive impairment and an unsafe environment, in which the patient's 91-year-old husband stored kerosene in an old shochu bottle, were responsible for the accidental ingestion. Acute exogenous lipoid pneumonia should be considered in the differential diagnosis for acute respiratory disorders in the rapidly aging population. PMID:23286561

Conclusiones: Los resultados del presente análisis sugieren la ausencia de efectos globales de la provisión de antihipertensivossobre la mortalidad por accidente cerebrovascular. Sin embargo, los datos muestran que, entre los grupos más desfavorecidos,la distribución de antihipertensivos estuvo asociada con una reducción de la mortalidad por esta causa.

  14. Illustration of probabilistic approach in consequence assessment of accidental radioactive releases

    International Nuclear Information System (INIS)

    We are describing a certain application of uncertainty analysis of environmental model HARP applied on atmospheric and deposition sub-model. Simulation of uncertainties propagation through the model is basic inevitable task bringing data for advanced techniques of probabilistic consequence assessment and further improvement of reliability of model predictions based on statistical procedures of assimilation with measured data. The activities are investigated in the institute IITA AV CR within the grant project supported by GACR (2007-2009). The problem is solved in close cooperation with section of information systems in institute NRPI. The subject of investigation concerns evaluation of consequences of radioactivity propagation after an accidental radioactivity release from nuclear facility.Transport of activity is studied from initial atmospheric propagation, deposition of radionuclides on terrain and spreading through food chains towards human body .Subsequent deposition processes of admixtures and food chain activity transport are modeled. In the final step a hazard estimation based on doses on population is integrated into the software system HARP. Extension to probabilistic approach has increased the complexity substantially, but offers much more informative background for modem methods of estimation accounting for inherent stochastic nature of the problem. Example of probabilistic assessment illustrated here is based on uncertainty analysis of input parameters of SGPM model. Predicted background field of Cs-137 deposition are labelled with index p. as PXSGPM. Final goal is estimation of a certain unknown true background vector χtrue, which accounts also for deficiencies of the SGPM formulation in itself insisting in insufficient description of reality. We must have on mind, that even if we know true values of all input parameters θmtrue (m= 1 ,..., M) of SGPM model, the χtrue still remain uncertain. One possibility how to approach reality insists in

  15. Modelling of tritium dispersion from postulated accidental release of nuclear power plants

    International Nuclear Information System (INIS)

    This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models of hydrodynamics and transport for the simulation of tritium dispersion caused by an accident in a CANDU reactor located in the ongoing Angra 3 site. This exercise was accomplished with the aid of a code system (SisBAHIA) developed in the Rio de Janeiro Federal University (COPPE/UFRJ). The CANDU reactor is one that uses heavy water (D2O) as moderator and coolant of the core. It was postulated, then, the LOCA (Loss of Coolant Accident) accident in the emergency cooling system of the nucleus (without fusion), where was lost 66 m3 of soda almost instantaneously. This inventory contained 35 PBq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios (plant stopped and operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1 MBq/m3 ) during the first 14 days after the accident. The main difference between the scenario without and with seawater recirculation (pumping and discharge) is based on the enhancement of dilution of the highest concentrations in the last one. This dilution enhancement resulting in decreasing concentrations was observed only during the first two weeks, when they ranged from 1x109 to 5x105 Bq/m3 close to the Itaorna beach spreading just to Sandri Island. After 180 days, the plume could not be detected anymore in the bay, because their activities would be lower than the minimum detectable value (3). (author)

  16. Rapid removal of sodium isotopes from the body following accidental internal contamination

    International Nuclear Information System (INIS)

    The extensive use of liquid sodium as the primary coolant for fast breeder reactors presents human safety hazards from both the chemical toxicity of the sodium oxide and the radioactive toxicity of the large quantities of 24Na and 22Na in case of a rupture in the liquid sodium piping. Although the effects of the chemical toxicity are expected to be very immediate and more severe, the radioactive toxicity is also of significant concern. Other sources of radioactive sodium contamination exist in the nuclear industry. This paper describes some procedures which can significantly reduce the radiation dose to the body from 24Na and 22Na which might be accidentally inhaled or ingested. Studies with rats indicate that the retention time of the sodium isotopes which have exchanged with the body sodium pool can be reduced by a factor of 10 by ingestion of high levels of stable sodium. In addition, the ingestion of a sodium salt at the time or immediately after the inhalation incident could result in at least 60 percent or more of the inhaled radioactive sodium to be excreted before it exchanges with the body sodium pool. The combined effects of both immediate and sustained sodium ingestion in rats can result in a radiation dose from 22Na of only 4 percent or less of that which would result if no additional salt is administered. The dose reduction for 24Na would not be as much as that for 22Na but would be significant. The tolerance for high levels of stable sodium intake in humans will be discussed and optimum intakes will be suggested which will provide the maximum radioactive sodium excretion with minimum harm to the physiological processes of the body

    Sulfur mustard (SM) is a chemical warfare agent (CWA) that was first used in World War I and in several military conflicts afterwards. The threat by SM is still present even today due to remaining stockpiles, old and abandoned remainders all over the world as well as to its ease of synthesis. CWA are banned by the Chemical Weapons Convention (CWC) interdicting their development, production, transport, stockpiling and use and are subjected to controlled destruction. The present case report describes an accidental exposure of three workers that occurred during the destruction of SM. All exposed workers presented a characteristic SM-related clinical picture that started about 4h after exposure with erythema and feeling of tension of the skin at the upper part of the body. Later on, superficial blister and a burning phenomenon of the affected skin areas developed. Similar symptoms occurred in all three patients differing severity. One patient presented sustained skin affections at the gluteal region while another patient came up with affections of the axilla and genital region. Fortunately, full recovery was observed on day 56 after exposure except some little pigmentation changes that were evident even on day 154 in two of the patients. SM-exposure was verified for all three patients using bioanalytical GC MS and LC MS/MS based methods applied to urine and plasma. Urinary biotransformation products of the β-lyase pathway were detected until 5 days after poisoning whereas albumin-SM adducts could be found until day 29 underlining the beneficial role of adduct detection for post-exposure verification. In addition, we provide general recommendations for management and therapy in case of SM poisoning.

Lima is the most affected region, presenting 61.7% of the accidents, the annual cost reached one thousand million dollars, equivalent to a third part of the investment in health. Available studies give emphasis to the protagonists -the drivers, the pedestrians- or to equipment and roads; the laws have been modified and containment plans for accidents have been implemented, but the incidence remains the same. We raise the possibility of exploring behavioral and social factors that could be relevant in the genesis of the problem, revising those related to current disorder in transport, the behaviors of drivers and pedestrians and the permissiveness of society in general particularly of the authority. We propose research and a multidisciplinary and intersectoral intervention.

    Full Text Available A scientist in our laboratory was accidentally infected while working with Z5463, a Neisseria meningitidis serogroup A strain. She developed severe symptoms (fever, meningism, purpuric lesions that fortunately evolved with antibiotic treatment to complete recovery. Pulse-field gel electrophoresis confirmed that the isolate obtained from the blood culture (Z5463BC was identical to Z5463, more precisely to a fourth subculture of this strain used the week before the contamination (Z5463PI. In order to get some insights into genomic modifications that can occur in vivo, we sequenced these three isolates. All the strains contained a mutated mutS allele and therefore displayed an hypermutator phenotype, consistent with the high number of mutations (SNP, Single Nucleotide Polymorphism detected in the three strains. By comparing the number of SNP in all three isolates and knowing the number of passages between Z5463 and Z5463PI, we concluded that around 25 bacterial divisions occurred in the human body. As expected, the in vivo passage is responsible for several modifications of phase variable genes. This genomic study has been completed by transcriptomic and phenotypic studies, showing that the blood strain used a different haemoglobin-linked iron receptor (HpuA/B than the parental strains (HmbR. Different pilin variants were found after the in vivo passage, which expressed different properties of adhesion. Furthermore the deletion of one gene involved in LOS biosynthesis (lgtB results in Z5463BC expressing a different LOS than the L9 immunotype of Z2491. The in vivo passage, despite the small numbers of divisions, permits the selection of numerous genomic modifications that may account for the high capacity of the strain to disseminate.

  1. Assessment of methodologies for analysis of the dungeness B accidental aircraft crash risk.

    The Health and Safety Executive (HSE) has requested Sandia National Laboratories (SNL) to review the aircraft crash methodology for nuclear facilities that are being used in the United Kingdom (UK). The scope of the work included a review of one method utilized in the UK for assessing the potential for accidental airplane crashes into nuclear facilities (Task 1) and a comparison of the UK methodology against similar International Atomic Energy Agency (IAEA), United States (US) Department of Energy (DOE), and the US Nuclear Regulatory Commission (NRC) methods (Task 2). Based on the conclusions from Tasks 1 and 2, an additional Task 3 would provide an assessment of a site-specific crash frequency for the Dungeness B facility using one of the other methodologies. This report documents the results of Task 2. The comparison of the different methods was performed for the three primary contributors to aircraft crash risk at the Dungeness B site: airfield related crashes, crashes below airways, and background crashes. The methods and data specified in each methodology were compared for each of these risk contributors, differences in the methodologies were identified, and the importance of these differences was qualitatively and quantitatively assessed. The bases for each of the methods and the data used were considered in this assessment process. A comparison of the treatment of the consequences of the aircraft crashes was not included in this assessment because the frequency of crashes into critical structures is currently low based on the existing Dungeness B assessment. Although the comparison found substantial differences between the UK and the three alternative methodologies (IAEA, NRC, and DOE) this assessment concludes that use of any of these alternative methodologies would not change the conclusions reached for the Dungeness B site. Performance of Task 3 is thus not recommended.

    This study applied the American Meteorological Society and Environmental Protection Agency Regulatory Model (AERMOD) to assess the risk caused by an accidental release and dispersion of the toxic chemical benzene in the vicinity of a highly populated urban area. The modeling domain encompasses the Korean megacity of Ulsan, which includes two national industrial complexes and is characterized by a complex coastal terrain. Multiple AERMOD simulations were conducted for an assumed emission scenario using background wind data from August between 2009 and 2013. The series of experiments produced the spatial accident probability patterns for different concentration levels during daytime and nighttime scenarios based on the corresponding dominant wind patterns. This study further quantifies the potential accident risk based on the number of affected individuals by combining the accident probability with the indoor and outdoor population estimates. The chemical gas dispersion characteristics depend on various local meteorological conditions, such as the land-sea breeze direction, which alternates between daytime and nighttime, and the atmospheric stability. The results reveal that benzene dispersion affects a much larger area during the nighttime owing to the presence of a nocturnal stable boundary layer with significant temperature stratification. The affected area is smaller during the daytime owing to decreased stability and enhanced vertical mixing in the boundary layer. The results include a high degree of uncertainty during the nighttime owing to weak wind speeds and the lack of a prevailing wind direction, which impact the vulnerable area. However, vulnerable areas are more effectively identified during the daytime, when more consistent meteorological conditions exist. However, the potential risk becomes much lower during the nighttime owing to a substantial reduction of the outdoor population.

    The recent detection of the cosmic microwave background polarimeter experiment BICEP2 of tensor fluctuations in the B-mode power spectrum basically excludes all plausible axion models where its decay constant is above 10{sup 13} GeV. Moreover, there are strong theoretical, astrophysical, and cosmological motivations for models involving, in addition to the axion, also axion-like particles (ALPs), with decay constants in the intermediate scale range, between 10{sup 9} GeV and 10{sup 13} GeV. Here, we present a general analysis of models with an axion and further ALPs and derive bounds on the relative size of the axion and ALP photon (and electron) coupling. We discuss what we can learn from measurements of the axion and ALP photon couplings about the fundamental parameters of the underlying ultraviolet completion of the theory. For the latter we consider extensions of the Standard Model in which the axion and the ALP(s) appear as pseudo Nambu-Goldstone bosons from the breaking of global chiral U(1) (Peccei-Quinn (PQ)) symmetries, occuring accidentally as low energy remnants from exact discrete symmetries. In such models, the axion and the further ALP are protected from disastrous explicit symmetry breaking effects due to Planck-scale suppressed operators. The scenarios considered exploit heavy right handed neutrinos getting their mass via PQ symmetry breaking and thus explain the small mass of the active neutrinos via a seesaw relation between the electroweak and an intermediate PQ symmetry breaking scale. We show some models that can accommodate simultaneously an axion dark matter candidate, an ALP explaining the anomalous transparency of the universe for γ-rays, and an ALP explaining the recently reported 3.55 keV gamma line from galaxies and clusters of galaxies, if the respective decay constants are of intermediate scale.

    Water quality degradation in harbour domains can have an important negative impact from an economic, touristic and environmental point of view. In that sense, water quality management is becoming a main concern for harbour managers. In this paper, we present the research behind the initiative started in Spanish harbours to control water quality degradation due to accidental pollution. This management system is already operationally running in the Barcelona harbour (NW Mediterranean Sea). The system is based on a recent published risk assessment, which takes into account not only the different activities in the harbour and their inherent risk of accident but also the physical behaviour of harbour waters. In this methodology, a key element is to get hydrodynamic forecasts. Thus, the system is composed of a hierarchy of nested hydrodynamic models covering from the basin scale to the harbour scale and a module that computes the different parameters needed for risk assessment. Special emphasis is made on describing the steps followed for system implementation because such implementation is far from a mere technical problem. The first step is to identify the main forcing factors for the harbour hydrodynamics from both field data and numerical experiments, which has never been done before for the Barcelona harbour. Wind and shelf currents are suggested as the main forcing factors for the harbour circulation. The second step is to identify the requirements that a numerical model must fulfil in order to properly solve the Barcelona harbour's hydrodynamics. A high resolution (< 50 m) three dimensional model able to prognostically calculate temperature and salinity evolution; full air-sea coupling is needed as well. The third step is to investigate the best operational strategy. We have found that small errors in the initial density profiles are acceptable for surface current forecasts but not for deep circulation. A cold start must be avoided and a 72 h spin-up is

  7. Study on plutonium distribution in Palomares ecosystem after an accidental aerosol release of transuranic radionuclides

    International Nuclear Information System (INIS)

    A discharge of plutonium and transuranic elements accidentally ocurred near Palomares (Almeria, Spain) in 1966. After decontamining operations, about 10 g of finely dispersed plutonium remained on the soil and was spreaded on the sorroundings and into Mediterranean sea. An analytical study including a 34 sampling sites of marine sediments, chemical clean-up, analytical methods for isolating plutonium from interfering radionuclides in the alfa-spectra was carried out. The detection limit level reached for the 239 u+240Pu was 10 mBq/Kg one of the lowest cited in the Spanish analytical literature until now. These results were attained following a careful electroplating Pu deposition method developed by our laboratory as result of the high signal/noise rates measured and a 20 KeV resolution. Several analytical assurance quality procedures specially developed for the Palomares ecological system were applied to the results, at the CIEMAT laboratories using reference standard certified samples. The values were unbiased and with no differences statistically significants between them. Interlaboratory comparisons were carried out. After 20 years of plutonium traces environmental transport their concentration were from two at three times the leves of radionuclides in the fallout of the zone studied. The plutonium concentration range in surface sediments was 0.3-5.0 Bq/Kg. The highest values corresponding in the coastal sediments and the lowest in the deep sea. Plutonium concentrations are highly correlated with the sediments structure, grain size composition and distance from the mouth of Almanzora river. The most important contribution at the transport from the land into sea could be the freshet occured at 1973. For this reason the plutonium ecologycal path has been from Palomares sorroundings into the sea. Sites in the Mediterranean sea not affected by plutonium apportation from Almanzora river showed Pu levels approximately the same as the mean value for the whole

  8. Probabilistic margin evaluation on accidental transients for the ASTRID reactor project

    ASTRID is a technological demonstrator of Sodium cooled Fast Reactor (SFR) under development. The conceptual design studies are being conducted in accordance with the Generation IV reactor objectives, particularly in terms of improving safety. For the hypothetical events, belonging to the accidental category "severe accident prevention situations" having a very low frequency of occurrence, the safety demonstration is no more based on a deterministic demonstration with conservative assumptions on models and parameters but on a "Best-Estimate Plus Uncertainty" (BEPU) approach. This BEPU approach ispresented in this paper for an Unprotected Loss-of-Flow (ULOF) event. The Best-Estimate (BE) analysis of this ULOFt ransient is performed with the CATHARE2 code, which is the French reference system code for SFR applications. The objective of the BEPU analysis is twofold: first evaluate the safety margin to sodium boiling in taking into account the uncertainties on the input parameters of the CATHARE2 code (twenty-two uncertain input parameters have been identified, which can be classified into five groups: reactor power, accident management, pumps characteristics, reactivity coefficients, thermal parameters and head losses); secondly quantify the contribution of each input uncertainty to the overall uncertainty of the safety margins, in order to refocusing R&D efforts on the most influential factors. This paper focuses on the methodological aspects of the evaluation of the safety margin. At least for the preliminary phase of the project (conceptual design), a probabilistic criterion has been fixed in the context of this BEPU analysis; this criterion is the value of the margin to sodium boiling, which has a probability 95% to be exceeded, obtained with a confidence level of 95% (i.e. the M5,95percentile of the margin distribution). This paper presents two methods used to assess this percentile: the Wilks method and the Bootstrap method ; the effectiveness of the two methods

    As part of the 5th National Audit Project of the Royal College of Anaesthetists and the Association of Anaesthetists of Great Britain and Ireland concerning accidental awareness during general anaesthesia, we issued a questionnaire to every consultant anaesthetist in each of 46 public hospitals in Ireland, represented by 41 local co-ordinators. The survey ascertained the number of new cases of accidental awareness becoming known to them for patients under their care or supervision for a calendar year, as well as their career experience. Consultants from all hospitals responded, with an individual response rate of 87% (299 anaesthetists). There were eight new cases of accidental awareness that became known to consultants in 2011; an estimated incidence of 1:23 366. Two out of the eight cases (25%) occurred at or after induction of anaesthesia, but before surgery; four cases (50%) occurred during surgery; and two cases (25%) occurred after surgery was complete, but before full emergence. Four cases were associated with pain or distress (50%), one after an experience at induction and three after experiences during surgery. There were no formal complaints or legal actions that arose in 2011 related to awareness. Depth of anaesthesia monitoring was reported to be available in 33 (80%) departments, and was used by 184 consultants (62%), 18 (6%) routinely. None of the 46 hospitals had a policy to prevent or manage awareness. Similar to the results of a larger survey in the UK, the disparity between the incidence of awareness as known to anaesthetists and that reported in trials warrants explanation. Compared with UK practice, there appears to be greater use of depth of anaesthesia monitoring in Ireland, although this is still infrequent.

    Every year, 270,000 tonnes of oil are estimated to be spilled in the ocean by vessel operations (e.g. tank washing, leakage of lubricants) and the so called operational spills are typically associated with small volumes and high occurrence rate. Vessel-related accidental spills (e.g. collisions, explosions) seldom occur and usually involve high volumes of oil, accounting for about 100,000 tonnes/year. The occurrence of accidental spills and their impacts have been well documented in the available literature. On the other hand, occurrence rates of operational spills and the effects they have on the marine and coastal environments remain very uncertain due to insufficient sampling effort and methodological limitations. Trying to foresee when and where an oil spill will occur in a certain area, its characteristics and impacts is, at present, impossible. Oil spill risk assessments (OSRAs) have been employed in several parts of the globe in order to deal with such uncertainties and protect the marine environment. In the present work, we computed the oil spill risk applying ensemble oil spill simulations following an ISO-31000 compliant OSRA methodology (Sepp Neves et al. , 2015). The ensemble experiment was carried out for the Algarve coast (southern Portugal) generating a unique data set of 51,200 numerical oil spill simulations covering the main sources of uncertainties (i.e. where and when the spill will happen and oil spill model configuration). From the generated data set, the risk due to accidental and operational spills was mapped for the Algarve municipalities based on the frequency and magnitude (i.e. concentrations) of beaching events and the main sources of risk were identified. The socioeconomic and environmental dimensions of the risk were treated separately. Seasonal changes in the risk index proposed due to the variability of meteo-oceanographic variables (i.e. currents and waves) were also quantified.

    Highlights: ► Ground vibration due to the collapse of a huge cooling tower was predicted. ► Accidental loads with different characteristics caused different collapse modes. ► Effect of ground vibration on the nuclear-related facilities cannot be ignored. -- Abstract: A comprehensive approach is presented in this study for the prediction of the ground vibration due to the collapse of a 235 m high cooling tower, which can be caused by various accidental loads, e.g., explosion or strong wind. The predicted ground motion is to be used in the safety evaluation of nuclear-related facilities adjacent to the cooling tower, as well as the plant planning of a nuclear power station to be constructed in China. Firstly, falling weight tests were conducted at a construction site using the dynamic compaction method. The ground vibrations were measured in the form of acceleration time history. A finite element method based “falling weight-soil” model was then developed and verified by field test results. Meanwhile, the simulated collapse processes of the cooling tower under two accidental loads were completed in a parallel study, the results of which are briefly introduced in this paper. Furthermore, based on the “falling weight-soil” model, “cooling tower-soil” models were developed for the prediction of the ground vibrations induced by two collapse modes of the cooling tower. Finally, for a deep understanding of the vibration characteristics, a parametric study was also conducted with consideration of different collapse profiles, soil geologies as well as the arrangements of an isolation trench. It was found that severe ground vibration occurred in the vicinity of the cooling tower when the collapse happened. However, the vibration attenuated rapidly with the increase in distance from the cooling tower. Moreover, the “collapse in integrity” mode and the rock foundation contributed to exciting intense ground vibration. By appropriately arranging an isolation

    International Nuclear Information System (INIS)

    The propagation of a blast wave inside the Darlington Nuclear Generating Station NGS) powerhouse following an accidental explosion at a nearby railway line has been studied numerically using two different computer codes. Pressurization of the building interior at various locations in the powerhouse are computed with an Ontario Hydro in-house finite-difference containment code called PATRIC, and in one benchmark case with an Institute for Aerospace Studies code based on the random-choice method, both of which solve unsteady one-dimensional flow problems. Some pertinent results of both codes are presented, and they are also shown to be in good agreement

    This case series highlights three patients with Parkinson's disease residing at nursing home facilities whose deep brain stimulators were accidentally deactivated for varying lengths of time, which was associated with an increase in falls. In all three cases, neither the patients nor the caregivers were aware of the random deactivations/reactivations. We propose a specific care plan for these patients that includes further education of caregivers regarding deep brain stimulators and regular checks of the review device, especially when there is concern about a patient's mobility or balance that is out of character.

  7. Proposal of procedures to prevent errors in radiotherapy based in learned lessons of accidental expositions

    International Nuclear Information System (INIS)

    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 these errors do not

  8. Historical Doses To The Public from Routine and Accidental Releases of Tritium - Lawrence Livermore National Laboratory, 1953 - 2005

    Throughout fifty-three years of operations, an estimated 29,300 TBq of tritium have been released to the atmosphere at the Livermore site of Lawrence Livermore National Laboratory; about 75% of this was released accidentally as gaseous tritium in 1965 and 1970. Routine emissions contributed slightly more than 3,700 TBq gaseous tritium and about 2,800 TBq tritiated water vapor to the total. Mean annual doses (with 95% confidence intervals) to the most exposed member of the public were calculated for all years using the same model and the same assumptions. Because time-dependent tritium models require detailed meteorological data that were unavailable for the large releases, ingestion/inhalation dose ratios were derived from experience with UFOTRI. Even with assumptions to assure that doses would not be underestimated, all doses from routine and accidental releases were below the level (3.6 mSv) at which adverse health effects have been documented, and most were below the current regulatory limit of 100 {micro}Sv per year from releases to the atmosphere.

  9. Normal neurologic and developmental outcome after an accidental intravenous infusion of expressed breast milk in a neonate.

    2012-02-03

    Here we describe a premature male infant who was accidentally given 10 mL of expressed breast milk intravenously over a 3.5-hour period. Having survived this event with supportive care, this boy was attending regular school with no obvious neurologic or learning difficulties at 6 years of age. In 1998, after a query on an e-mail discussion group for health care providers in neonatology (NICU-net), we were informed of 8 similar events that proved fatal in 3 infants. A root-cause analysis revealed that accidental intravenous administration of breast milk or formula can be avoided by the use of color-coded enteral-administration sets with Luer connections that are not compatible with intravenous cannulas. The addition of methylene blue to feeds, or bolus enteral feeds (instead of continuous gastric feedings), may also help prevent such errors. These cases show the value of gathering information about rare but important events through a neonatal network. In addition, they confirm that prevention of medical error should focus on faulty systems rather than faulty people.

    Bulk black phosphorus has two optical phonon modes labeled as Ag (2) and B2u, respectively, that are nearly degenerate in frequency. However, density functional theory calculations using local or semi-local functionals cannot reproduce this degeneracy. Here, we propose a hybrid functional approach aided by van der Waals (vdW) force fields, which can accurately describe the lattice dynamic and electronic properties of both bulk and few-layer black phosphorus (phosphorene). Using this approach we show that in bilayer phosphorene, the two Raman modes derived from the B2u and Ag (2) modes could exhibit strong resonance as a result of the accidental degeneracy so that both modes could be observed in Raman experiment. Without the mode degeneracy, however, the Raman intensity of the B2u-derived mode would be too weak to be observed. We further show that the accidental degeneracy is correlated to the applied strain, which enables Raman spectroscopy to be a powerful tool for characterizing built-in strains in 2D materials, e.g., due to the interaction with substrates, which has emerged as an important issue in vdW epitaxy.

    Core social interaction behaviors were examined in young children 0-36 months of age who were hospitalized for accidental (n = 61) or inflicted (n = 64) traumatic brain injury (TBI) in comparison to typically developing children (n = 60). Responding to and initiating gaze and joint attention (JA) were evaluated during a semi-structured sequence of social interactions between the child and an examiner at 2 and 12 months after injury. The accidental TBI group established gaze less often and had an initial deficit initiating JA that resolved by the follow-up. Contrary to expectation, children with inflicted TBI did not have lower rates of social engagement than other groups. Responding to JA was more strongly related than initiating JA to measures of injury severity and to later cognitive and social outcomes. Compared to complicated-mild/moderate TBI, severe TBI in young children was associated with less responsiveness in social interactions and less favorable caregiver ratings of communication and social behavior. JA response, family resources, and group interacted to predict outcomes. Children with inflicted TBI who were less socially responsive and had lower levels of family resources had the least favorable outcomes. Low social responsiveness after TBI may be an early marker for later cognitive and adaptive behavior difficulties. PMID:23507345

    Full Text Available Certain environmental microorganisms can cause severe human infections, even in the absence of an obvious requirement for transition through an animal host for replication ("accidental virulence". To understand this process, we compared eleven isolate genomes of Burkholderia pseudomallei (Bp, a tropical soil microbe and causative agent of the human and animal disease melioidosis. We found evidence for the existence of several new genes in the Bp reference genome, identifying 282 novel genes supported by at least two independent lines of supporting evidence (mRNA transcripts, database homologs, and presence of ribosomal binding sites and 81 novel genes supported by all three lines. Within the Bp core genome, 211 genes exhibited significant levels of positive selection (4.5%, distributed across many cellular pathways including carbohydrate and secondary metabolism. Functional experiments revealed that certain positively selected genes might enhance mammalian virulence by interacting with host cellular pathways or utilizing host nutrients. Evolutionary modifications improving Bp environmental fitness may thus have indirectly facilitated the ability of Bp to colonize and survive in mammalian hosts. These findings improve our understanding of the pathogenesis of melioidosis, and establish Bp as a model system for studying the genetics of accidental virulence.

  15. Final Report: Safety of Plasma Components and Aerosol Transport During Hard Disruptions and Accidental Energy Release in Fusion Reactor

    Energy Technology Data Exchange (ETDEWEB)

    Bourham, Mohamed A.; Gilligan, John G.

    1999-08-14

    Safety considerations in large future fusion reactors like ITER are important before licensing the reactor. Several scenarios are considered hazardous, which include safety of plasma-facing components during hard disruptions, high heat fluxes and thermal stresses during normal operation, accidental energy release, and aerosol formation and transport. Disruption events, in large tokamaks like ITER, are expected to produce local heat fluxes on plasma-facing components, which may exceed 100 GW/m{sup 2} over a period of about 0.1 ms. As a result, the surface temperature dramatically increases, which results in surface melting and vaporization, and produces thermal stresses and surface erosion. Plasma-facing components safety issues extends to cover a wide range of possible scenarios, including disruption severity and the impact of plasma-facing components on disruption parameters, accidental energy release and short/long term LOCA's, and formation of airborne particles by convective current transport during a LOVA (water/air ingress disruption) accident scenario. Study, and evaluation of, disruption-induced aerosol generation and mobilization is essential to characterize database on particulate formation and distribution for large future fusion tokamak reactor like ITER. In order to provide database relevant to ITER, the SIRENS electrothermal plasma facility at NCSU has been modified to closely simulate heat fluxes expected in ITER.

  19. Simulation of thermal hydraulics accidental transients. Evaluation of MAAP5.02 versus CATHAREv2.5

    International Nuclear Information System (INIS)

    The Modular Accident Analysis Program (MAAP) is a deterministic code developed by EPRI that can simulate the response of light water moderated nuclear power plants during accidental transients for Probabilistic Risk Analysis (PRA) applications. It can as well simulate severe accident sequences, including actions taken as part of the Severe Accident Management Guidelines (SAMGs). EPRI indicates that the latest version of the code - MAAP5.02 - benefits from major enhancements, in particular concerning the thermal hydraulics in the primary side. This code revision takes into account momentum equations allowing, to model thermal hydraulics transient with a good accuracy. EDF is interested in using MAAP5.02 as an incidental/accidental transient’s simulation tool for the management of crises on its 58 PWRs. In particular, it could evaluate the time before core uncovers, core melting and fission product releases. In order to assess MAAP5.02 ability to simulate accidental transients prior to core uncovery, EDF has compared MAAP5.02 results to the code used as a reference to simulate thermal hydraulics transients in France: CATHARE (that stands for Code for Analysis of Thermal hydraulics during an Accident of Reactor and safety Evaluation). CATHARE is a system code for PWR safety analysis, accident management, definition of plant operating procedures and for research and development. It is also used to quantify conservative analysis margins and for licensing. It is based on a 2-fluid 6-equation model. The version of CATHARE used for the comparison is CATHAREv2.5–2 (one of the latest CATHARE versions). Several transient analyses on LOCA and non LOCA transients have been performed by EDF. Transients at full power conditions as well as in shutdown states have been considered. Here are some of EDF analyzed transients: LOCA (small break on cold leg), LOOP (Loss Of Offsite Power), SGTR (Steam Generator Tube Rupture). The comparisons performed tend to prove that the

Experts and delegates from member countries presented papers, participated in discussions and workshops and produced a multidisciplinary report covering the topic areas. Two volumes were produced; one a collection of all papers presented, and the other a compilation of the proceedings from each of the topic workshops. In order to rapidly distribute the Association's information to members, papers and other information were collated and disseminated as presented to the conference participants

  1. Chromosome damage and clinical manifestation in a fetus and the mother after accidental 60Co exposure in Xinzhou

    International Nuclear Information System (INIS)

    The authors present the clinical effect and chromosome damage sustained by a fetus and the four months pregnant mother in an accidental 60Co exposure in November of 1992 in Xinzhou, Shanxi Province. The mother suffered from a moderate acute radiation sickness with ratardation of fetal development. After delivery, the infant's body length, body weight and head circumference were all lowered by three percentiles compared with the normals. Four months after the exposure, the assay of the mother's peripheral lymphocytes showed a chromosome aberration rate of 36%, while concomitant examination of the baby failed to reveal any chromosome abnormality although the sister chromatid exchange rate was remarkably higher than that of the mother and the normal control

    This article takes its cue from the original work of sir Alexander Fleming on penicillin, published in the first issue of Recenti Progressi in Medicina in 1946 and reproduced here on the occasion of the approaching 70-year anniversary of the journal. The path that brought Fleming to the discovery of penicillin, one of the major milestones in the history of clinical pharmacology, provides insight for a range of considerations: the painstaking efforts of researchers, the contribution from accidental findings, and the dissemination of study results. Although the discovery of penicillin has changed the course of medicine, the benefits deriving from such an important advance are most likely to be offset by the overprescription of antibiotics, which is the leading cause of antimicrobial resistance and one of the most serious public health problems of our time.

  4. Visits to Australia by nuclear powered or armed vessels: contingency planning for the accidental release of ionizing radiation

    International Nuclear Information System (INIS)

    The adequacy of current contingency planning by Federal and State authorities to deal with the accidental release of ionizing radiation from visiting nuclear powered or armed vessels in Australian waters and ports is reported on and 39 recommendations are made. After introductory chapters, the remainder of the report consists of two parts. Chapters 3 to 10 deal with the main issues relating to nuclear powered warship (NPW) visits and the adequacy of current contingency plans. Chapters 11 to 13 deal with the question whether any specific planning is required for visits by nuclear weapons capable warships. In part one the present emergency arrangements and criticisms of the current plans are reviewed. The NPWs' reactors, safety records and visit arrangements in other countries are discussed. The validity of the reference accident on which current NPW emergency planning is based is assessed. In part two nuclear weapons and their accidents are reviewed. The dissenting report of one of the Senators is included

    This report describes a comparison of the MARC (Methodology for Assessing Radiological Consequences) and CRAC2 (Calculation of Reactor Accident Consequences, version 2) computer programs for assessing the radiological consequences of accidental releases of radioactive material. A qualitative comparison has been made of the features of the constituent sub-models of the two codes, and potentially the most important differences identified. The influence of these differences has been investigated quantitatively by comparison of the predictions of the two codes in a wide variety of circumstances. Both intermediate quantities and endpoints used as a measure of risk have been compared in order to separate the variables more clearly. The results indicate that, in general, the predictions of MARC and CRAC2 are in good agreement.

    Spinally administered opioids must be a last step in the therapeutical arsenal of chronic benigne pain. It is an invasive technique not free from adverse effects. Two chronic pain patients received an implantable Synchromed pump for treatment with spinal opiates after a trial period of resp. 3.5 and 5.5 months. Due to a misprogrammation (both on the same day) they received very high doses of spinal opiates. This caused relatively few side effects, which did not seem to require immediate treatment. A short time development of tolerance to life threatening side-effects has been proven by this accidental administration of high-dose intraspinal opiates. It is critical that care providers are knowledgeable and well-trained about implantable infusion systems. Programmation and refills must always be performed with care. PMID:9259873

    2014-01-01

    In this paper we propose a symmetric q-deformed Tamm-Dancoff (S-TD) oscillator algebra and study its representation, coordinate realization, and main properties. In particular, the non-Fibonacci (more exactly, quasi-Fibonacci) nature of S-TD oscillator is established, the possibility of relating it to certain p,q-deformed oscillator family shown, the occurrence of the pairwise accidental degeneracy proven. We also find the coherent state for the S-TD oscillator and show that it satisfies completeness relation. Main advantage of the S-TD model over usual Tamm-Dancoff oscillator is that due to (qq^{-1})-symmetry it admits not only real, but also complex (phase-like) values of the deformation parameter q.

    Foreign body (FB) aspiration is commonly seen in children but less commonly in adolescents. Headscarf pin aspiration is common in Muslim girls, who inappropriately place the pins between their lips while securing the scarf on the head. Bronchoscopy is the treatment modality of choice, and surgery is rarely required. An 11-year-old girl was admitted as a case of accidental aspiration of headscarf pin. X-ray chest showed a radiopaque object in the left bronchus piercing the lung parenchyma. Computed tomography (CT) chest confirmed the diagnosis. The headscarf pin was removed by flexible bronchoscopy as the ear, nose, and throat (ENT) surgeon failed to remove it by rigid bronchoscopy. The FB was removed successfully and the patient was discharged home. Removal of a sharp pin by bronchoscopy is difficult, especially if it pierces the lung parenchyma. In our case, the pin was bent by forceps and then removed by a flexible bronchoscope, which requires a highly skilled professional. PMID:27578937

The results give evidence that facilities in San Juan Ixhuatepec had a moderate risk level which is in disagreement with people’s perception of the Pemex company, proprietary of the plant. This study concludes that the accident was mainly due to human error, as well as the inappropriate location of the plant.

  11. Evolution of N-species Kimura/voter models towards criticality, a surrogate for general models of accidental pathogens

    2012-09-01

    In models for accidental pathogens, with the paradigmatic epidemiological system of bacterial meningitis, there was evolution towards states exhibiting critical fluctuations with power law behaviour observed [1]. This is a model with many possibly pathogenic strains essentially evolving independently to low pathogenicity. A first and previous study had shown that in the limit of vanishing pathogenicity there are critical fluctuations with power law distributions observed, already when only two strains interact [2]. This earlier version of a two strain model was very recently reinvestigated [3] and named as Stollenwerk-Jansen model (SJ). Muñoz et al. demonstrated that this two-strain model for accidental pathogens is in the universality class of the so-called voter model. Though this model clearly shows criticality, its control parameter, the pathogenicity, is not self-tuning towards criticality. However, the multi-strain version mentioned above [1] is well evolving towards criticality, as well as a spatially explicit version of this, shown in [4] p. 155. These models of multi-strain type including explicitly mutations of the pathogenicity can be called SJ-models of type II [5]. Since the original epidemiological model is of SIRYX-type, the evolution to zero pathogenicity is slow and perturbed by large population noise. In the present article we now show on the basis of the notion of the voter-model universality classes the evolution of n-voter models with mutaion towards criticality, now much less perturbed by population noise, hence demonstrating a clear mechanism of self-organized criticality in the sense of [6, 7]. The present results have wide implications for many diseases in which a large proportion of infections is asymptomatic, meaning that the system has already evolved towards an average low pathogenicity. This holds not only for the original paradigmatic case of bacterial meningitis, but was reecently also suggested for example for dengue fever (DENFREE

    Full Text Available Objective: To explore the effect of a school-family-individual (SFI multi-level education intervention model on knowledge and attitudes about accidental injuries among school-aged children to improve injury prevention strategies and reduce the incidence of pediatric injuries. Methods: The random sample of rural school-aged children were recruited by using a multistage, stratified, cluster sampling method in Zunyi, Southwest China from 2012 to 2014, and 2342 children were randomly divided into intervention and control groups. Then children answered a baseline survey to collect knowledge and attitude scores (KAS of accidental injuries. In the intervention group, children, their parents/guardians and the school received a SFI multi-level education intervention, which included a children’s injury-prevention poster at schools, an open letter about security instruction for parents/guardians and multiple-media health education (Microsoft PowerPoint lectures, videos, handbooks, etc. to children. Children in the control group were given only handbook education. After 16 months, children answered a follow-up survey to collect data on accidental injury types and accidental injury-related KAS for comparing the intervention and control groups and baseline and follow-up data. Results: The distribution of gender was not significantly different while age was different between the baseline and follow-up survey. At baseline, the mean KAS was lower for the intervention than control group (15.37 ± 3.40 and 18.35 ± 5.01; p < 0.001. At follow-up, the mean KAS was higher for the intervention than control group (21.16 ± 3.05 and 20.02 ± 3.40; p < 0.001. The increase in KAS in the intervention and control groups was significant (p < 0.001; KAS: 5.79 vs. 1.67 and suggested that children’s injury-related KAS improved in the intervention group.

  19. Numerical and Experimental Investigations of Polyurethane Foam for Use as Cask Impact Limiter in Accidental Drop Scenarios - 12099

    International Nuclear Information System (INIS)

    Rigid, closed-cell polyurethane foams are frequently used as cask impact limiters in nuclear materials and hazardous waste transport due to their high energy-absorption potential. When assessing the cask integrity in accidental scenarios based on numerical simulations, a description of the foam damping properties is required for different strain rates and for a wide temperature range with respect to waste heat generation in conjunction with critical operating and environmental conditions. Implementation and adaption of a respective finite element material model strongly relies on an appropriate experimental data base. Even though extensive impact experiments were conducted e.g. in Sandia National Laboratories, Savannah River National Laboratory and by Rolls Royce plc, not all relevant factors were taken into account. Hence, BAM who is in charge of the mechanical evaluation of such packages within the approval procedure in Germany, incorporated systematic test series into a comprehensive research project aimed to develop numerical methods for a couple of damping materials. In a first step, displacement driven compression tests have been performed on confined, cubic specimens at five loading rates ranging from 0.02 mm/s to 3 m/s at temperatures between +90 deg. C and -40 deg. C. Materials include two different polyurethane foam types called FR3718 and FR3730 having densities of 280 kg/m3 and 488 kg/m3 from the product line-up of General Plastics Manufacturing Company. Their data was used to adapt an advanced plasticity model allowing for reliably simulating cellular materials under multi-axial compression states. Therefore, an automated parameter identification procedure had been established by combining an artificial neural network with local optimization techniques. Currently, the selected numerical material input values are validated and optimized by means of more complex loading configurations with the prospect of establishing methods applicable to impact

En el estudio, objeto de este trabajo, se analizan los resultados de las muestras de sangre obtenidas en las autopsias practicadas a los conductores en el Sur de España durante el año 2004. Los parámetros a considerar son: sexo, edad, fecha, concentración de etanol y consumo simultáneo de sustancias psicoativas que afecten la capacidad de conducción. Los análisis se han realizado siguiendo los procedimientos empleados habitualmente en el Instituto Nacional de Toxicología y Ciencias Forenses para este tipo de determinaciones, consistente en cromatografía de gases con detector FID para la determinación de alcoholemia; mientras que para las sustancias psicoactivas se realiza screening mediante CEDIA y posterior confirmación y cuantificación mediante cromatografía de gases con detector NPD y cromatografía de gases-espectrometría de masas. De los 495 casos recibidos, 232 correspondían a conductores, la mayoría de los cuales eran varones accidentados en la comunidad andaluza. Cabe destacar la incidencia de muertes en menores de 30 años, así como el consumo de alcohol entre los fallecidos, observándose en más de la mitad de estos casos una concentración de alcohol en sangre superior al límite permitido por la Dirección General de Tráfico, de 0,5 gramos de etanol por litro de sangre, superándose incluso, en muchos de ellos, la concentración de 1,5 g/l. Los resultados obtenidos confirman la importante relación entre los accidentes de tráfico mortales y el consumo de alcohol y sustancias psicoactivas.

    Full Text Available Fundamentos: En los países desarrollados los accidentes infantiles ocupan los primeros lugares como causa de mortalidad. El objetivo de este trabajo es describir su evolución en España desde 1975 a 1994, así como su distribución por Comunidades Autónomas. Método: Con las defunciones por accidentes y las poblaciones de España y sus Comunidades Autónomas de 1 a 14 años de las estadísticas oficiales de mortalidad se han calculado los siguientes indicadores: porcentajes sobre el total de defunciones, tasas brutas de mortalidad, tasas ajustadas por edad, tasas específicas por grupos de edad y riesgos relativos. Estos indicadores han sido calculados por género, año de defunción y Comunidad Autónoma. Resultados: Entre 1975 y 1994 se ha reducido la mortalidad por accidentes infantiles en España, en un 3% anual en las niñas y en un 3,5% en los niños. La razón niños/niñas se ha mantenido alrededor de 2. Los accidentes de tráfico han supuesto en torno al 50%. Aragón presentaba el riego relativo más bajo tanto en niñas como en niños, con 0,54 y 0,57 respectivamente, y Galicia el más alto con 1,73 en niñas y 1,91 en niños. El porcentaje sobre el total de defunciones infantiles fue muy variable entre las Comunidades Autónomas, mientras que el porcentaje de accidentes de tráfico estuvo alrededor del 50% en todas las Comunidades Autónomas. Conclusiones: En España la mortalidad por accidentes infantiles ha descendido de una manera notable, en la actualidad se estima que los niños mueren un 50% menos que en 1975. La distribución por Comunidades Autónomas presenta grandes diferencias.

    During clinical endodontic treatment, we often find radiopaque filling material beyond the root apex. Accidental extrusion of calcium hydroxide could cause the injury of inferior alveolar nerve, such as paresthesia or continuous inflammatory response. This case report presents the extrusion of calcium hydroxide and treatment procedures including surgical intervention. A 48 yr old female patient experienced Calcipex II extrusion in to the inferior alveolar canal on left mandibular area during endodontic treatment. After completion of endodontic treatment on left mandibular first molar, surgical intervention was planned under general anesthesia. After cortical bone osteotomy and debridement, neuroma resection and neurorrhaphy was performed, and prognosis was observed. But no improvement in sensory nerve was seen following surgical intervention after 20 mon. A clinician should be aware of extrusion of intracanal medicaments and the possibility of damage on inferior alveolar canal. Injectable type of calcium hydroxide should be applied with care for preventing nerve injury. The alternative delivery method such as lentulo spiral was suggested on the posterior mandibular molar.

    The exposures of urban populations to the radiation derived from the deposition, after accidental atmospheric releases, of 137 Cs, 134 Cs, 129 I, 131 I, 133 I, 89 Sr, 103 Ru and 106 Ru were assessed, using the integrated system for the evaluation of environmental radiological impact in emergency situations, developed by the Instituto de Radioprotecao e Dosimetria (IRD)/Comissao Nacional de Energia Nuclear (CNEN). These radionuclide are fission products likely to be emitted in the occurrence of severe nuclear reactor accidents. Their environmental behaviour in urban areas, due to their deposition in soil, in urban surfaces and in vegetable-garden food products, such as leafy and non-leafy vegetables, were analyzed, and dose assessments at the short, medium and long terms were performed, with an without the application of protective measures for reduction of doses. Simulations of unitary initial deposition for each radionuclide and of two different potential accidents involving water reactors (PWR), with different source terms and distinct deposition for each radionuclide, were performed. Results were analyzed on the basis of relative relevance of radionuclides and pathways for the exposure of members of the public, as a function of age and time after the release. It was also performed an assessment of the effectiveness of protective measures as a function of the moment of their implementation. (author)

    Oil Spill Risk Assessments (OSRAs) are widely employed to support decision making regarding oil spill risks. This article adapts the ISO-compliant OSRA framework developed by Sepp Neves et al. (J Environ Manag 159:158-168, 2015) to estimate risks in a complex scenario where uncertainties related to the meteo-oceanographic conditions, where and how a spill could happen exist and the risk computation methodology is not yet well established (ensemble oil spill modeling). The improved method was applied to the Algarve coast, Portugal. Over 50,000 simulations were performed in 2 ensemble experiments to estimate the risks due to operational and accidental spill scenarios associated with maritime traffic. The level of risk was found to be important for both types of scenarios, with significant seasonal variations due to the the currents and waves variability. Higher frequency variability in the meteo-oceanographic variables were also found to contribute to the level of risk. The ensemble results show that the distribution of oil concentrations found on the coast is not Gaussian, opening up new fields of research on how to deal with oil spill risks and related uncertainties.

    There are always various types of sudden accidental Water Pollution Events under the development of modern Chinese economy society, leading to serious economic losses and casualties. Water resources monitoring system, a real-time monitoring system, was built to monitor water quantity and quality of the important rivers and lakes over the country. Based on the system, we had brought up an idea to calculate the possibility of pollution and the risk of pollution in the watershed, and to deal with the threat of water pollution incidents effectively. It was proposed to build the greatest possible contamination with the most serious pollution values over the past years, and similarity test was carried on over the real-time monitoring of possible contamination value and the calculated value. In our study, taking Taihu River Basin as an example, we detailed the application progress of this method in water pollution incidents, the result shows that the method has a certain timeliness for the early warning of sudden water pollution incidents.

    Full Text Available Soil contamination represents an environmental issue which has become extremely important in the last decades due to the diffusion of industrial activities. Accidents during transport of dangerous materials and fuels may cause severe pollution. The present paper describes the criteria of the actions which were operated to remediate the potential risk and observed negative effects on groundwater and soil originating from an accidental spill of diesel fuel from a tank truck. With the aim to evaluate the quality of the involved environmental matrices in the “emergency” phase, in the following “safety” operation and during the remediation action, a specific survey on hydrocarbons, light and heavy, was carried out in the sand deposits soil. Elaboration of collected data allows us to observe the movement of pollutants in the unsaturated soil. The remediation action was finalized to improve the groundwater and soil quality. The former was treated by a so called “pump and treat” system coupled with air sparging. A train of three different technologies was applied to the unsaturated soil in a sequential process: soil vapour extraction, bioventing and enhanced bioremediation. Results showed that the application of sequential remediation treatments allowed us to obtain a state of quality in unsaturated soil and groundwater as required by Italian law.

    The calliphorid fly, Lucilia cuprina (Wiedemann), is known to cause serious malign myiasis in animals, whereas its sibling species Lucilia sericata (Meigen) is commonly a carrion breeder and is used in maggot debridement therapy (MDT). The current study reports an accidental involvement of L. cuprina in MDT in Alexandria, Egypt, that has proved to be safe and effective. In November 2008, the laboratory colonies of L. sericata (the species regularly used in MDT) at the Faculty of Science, Alexandria University were renewed by Lucilia flies collected as third instar larvae on exposed rabbit carcasses. Flies from the new colonies were successfully used to heal the diabetic foot wounds of two patients at Alexandria Main University Hospital. Analysis of DNA sequences and adult and larval morphology then revealed that these flies were and still are L. cuprina. Breeding of this species in carrion in Alexandria is a new record. Despite the safety of this strain of L. cuprina in MDT, entomologists rearing blow flies for the purpose of wound debridement should regularly maintain high quality assurance of their species' identity to avoid possible clinical complications that may result from the introduction of an unexpected and invasive species to their laboratory colonies.

    Full Text Available Abstract Three young men were trapped in a car at the bottom of a canal at two meters depth, after losing control of their vehicle. They were brought up by rescue divers and found in cardiac arrest. One of three patients had return of spontaneous circulation (ROSC, at 47 min after the accident. This sole survivor had the longest submersion time of the three and he received continued mechanical chest compressions during transportation to the hospital. His temperature at admission was 26.9°C, he was rewarmed to 33°C and kept there for 24 h, followed by continued rewarming to normothermia. On day three, he woke up from coma and was discharged from the intensive care unit after one week. At follow-up six months later, he had a complete cerebral recovery but still had myoclonic twitches in the lower extremities. A mechanical device facilitates chest compressions during transportation and may be beneficial as a bridge to final treatment in the hospital. We recommend that comatose patients after submersion, accidental hypothermia and cardiac arrest are treated with mild hypothermia for 12–24 h.

    In the present work, soil profiles were sampled 40 days and three years after an accidental pyrite tailing spill from the Aznalcóllar mine (S Spain) in order to figure out the effects of the acidic solution draining from the tailing. The composition of the acidic solution, the mineralogy, and the total and soluble content of the major elements were analysed at varying depths. The results show a weathering process of carbonates and of primary silicates. Calcium released is leached or reacts with the sulphate ions to form gypsum. Magnesium, aluminium and potassium tend to leach from the uppermost millimetres of the soil, accumulating where the pH>/=5.0; also the iron, probably forming more or less complex hydroxysulphates, precipitate in the upper 5 cm. The strong releasing of soluble salts increases the electrical conductivity, while the soluble potassium tends to decrease in the uppermost part of the soil due to the neoformation of jarosite. Iron is soluble only where the pH

    A next frontier of the global food safety agenda has to consider a broad spectrum of bio-risks, such as accidental and intentional contaminations in the food and feed chain. In this article, the background for the research needs related to biotraceability and response to bioterrorism incidents are outlined. Given the current scale of international trade any response need to be considered in an international context. Biotraceability (e.g. the ability to use downstream information to point to processes or within a particular food chain that can be identified as the source of undesirable agents) is crucial in any food-born outbreak and particular in the response to bioterrorism events. In the later case, tested and proven biotraceability improves the following: (i) international collaboration of validated tracing tools and detection methods, (ii) multi-disciplinary expertise and collaboration in the field of food microbiology and conceptual modeling of the food chain, (iii) sampling as a key step in biotracing (iv) optimized sample preparation procedures, including laboratory work in Biosafety level 3 (BSL-3) laboratories, (v) biomarker discovery for relevant tracing and tracking applications, and (vi) high-throughput sequencing using bio-informatic platforms to speed up the characterization of the biological agent. By applying biotraceability, the response phase during a bioterrorism event may be shortened and is facilitated for tracing the origin of biological agent contamination.

    Ingestion/aspiration episodes of foreign bodies are potential complications in almost all branches of dentistry. Occasionally, orthodontic appliances or small orthodontic components are accidentally swallowed and have caused problems with either the airway or the gastrointestinal tract, especially where the patient is supine or semi-recumbent. Despite their rare occurrence, the morbidity from a single incident and the level of specialized medical care that may be needed on emergency basis to manage such incidents is too high to ignore. Moreover, there is also the related risk of malpractice litigation given the fact that these incidents are preventable and increasing awareness among people. This article attempts to review potential risks and complications of ingestion/aspiration episodes based on relevant literature and describe the type of appliances and their parts most likely to cause problems. Certain recommendations based on best available evidence to minimize the incidence of such events are proposed, and strategies to aid the clinician in the event of such an emergency are also formulated.

    On Saturday morning, April 7, 1962, at about 1059 Armed Forces time, an accidental nuclear excursion occurred in the plutonium waste recovery facility (Recuplex) of the 234-5 Building. This excursion did not result in any mechanical damage or spread of contamination. Three employees of the General Electric Company received overexposures to gamma and neutron radiation. None were fatally exposed; in each case the overexposure was recognized promptly, and following medical observation and testing the men were released to return to work. In compliance with AEC Manual Chapter 0703, an AEC-HAPO committee composed of two AEC employees and five General Electric employees was appointed by the Manger, HOO, with the concurrence of the General Manager, HAPO, to conduct an investigation of the incident. The committee`s purpose was to determine the cause, nature, and extent of the incident, and recommend action to be taken by others to minimize or preclude future incidents of this magnitude. A study of operating practices and operating conditions that appeared to exist prior to, during, and subsequent to the accident was made by the committee. The committee believes that this report provides sufficient information to answer questions which may arise as a result of the criticality incident except those relating to its cause.

    Juvenile hyaline fibromatosis (JHF) is a rare disorder of unknown etiology, very few cases of which have been reported in the literature. It presents similarities to other fibromatosys, but has its particular radiological features which differentiate it from them. The clinical findings consist of several, slow growing, subcutaneous nodules, flexion contractures of the joints which can lead to disability, gingival hypertrophy and muscular atrophy. The suspected radiological diagnosis is confirmed by electron microscopy study of the nodules, although light microscopy can also reveal suggestive images. Author (9 refs.)

    Full Text Available São discutidos os aspectos relativos ao diagnóstico e tratamento dos hemangiomas cavernosos do crânio. Os dados obtidos em 26 casos, são apresentados, sendo salientado que a localização dos hemangiomas foi maior na região frontal, sendo mais atingido o sexo masculino. Os outros aspectos são coincidentes com os demais autores. A problemática desses tumores, principalmente a sua demonstração radiológica e o seu tratamento, são ressaltados, chegando-se à conclusão final de que o melhor meio de demonstração radiológica é a punção para contrastação direta do tumor. O tratamento de escolha é o cirúrgico, sendo a extirpação em bloco preferida nos casos de comprometimento ósseo importante, sendo a intervenção direta com dissecção e excisão reservada para as localizações nos tecidos moles ou com mínima participação óssea.

    Full Text Available Los motivos que inducen a una persona a enmascarar un suicidio simulando una muerte accidental pueden ser varios. Exponemos un caso en el que la víctima utiliza un accidente de tráfico para disimular un suicidio por arma de fuego y de esta forma conseguir que fuesen abonadas tanto la indemnización del Seguro de Automóviles como los incluidos en un seguro privado contratado poco antes. Sólo a través de una adecuada investigación del lugar de los hechos y de los antecedentes de la víctima junto a la realización del indispensable estudio necrópsico será posible determinar la verdadera etiología médico-legal de las muertes en accidente de tráfico, con especial atención en las que interviene sólo un vehículo con un único ocupante.There are several reasons that induce somebody to mask a suicide simulating an accidental death. We expose a case in which the victim uses a traffic accident to masquerade a suicide by shotgun. By this way, the author tries to receive the reimbursement of the car’s insurance as well as the money included in a private life insurance contracted just few days before. Only with the careful local death examination and the study of the victim's personal history, plus the essential autopsy, could we manage to understand the real aetiology of deaths in traffic accidents, especially focusing on those cases where there is a single car with a single passenger affected.

    Objective To describe the situation of child accidental injuries, to describe parents' awareness level of child accidental injuries and their safe-protective ability, to describe the situation of child safety education in parents, to study the relationship between parent cognition of child accidental injuries, their safe-protective ability and the incidence of child accidental injuries. Methods A descriptive non-experimental designed related research method was used. 120 parents of children received a questionnaire survey for cognition and safe-protective abihty of child accidental injuries in Dongshan District, Guangzhou City, in April 2009.SPSS11.0 software was used for statistical analysis. Results Rate of child accidental injuries was 66.7% and 67.5% of all accidental injuries occurred at home respectively. The two leading causes of accidental injuries are falls and burns. 85% parents were lack of safety education opportunities. Parents' understanding of child accidental injuries is not comprehensive enough and accident prevention measures are not sufficiently improved.There is a negative correlation between parent cognition of child accidental injuries, their daily safe-protective ability and the incidence of child accidental injuries, and there is a positive correlation between parent cognition of child accidental injuries and their awareness of child accidental injuries. Conclusions There is a high rate of child accidental injuries which mainly occurred at home, and falls are the leading reason for injuries, followed by burns. Parents' cognition and safe-protective ability of child accidental injuries are still required to be strengthened and improving parent cognition can contribute to capacity of child safe protection, which may decrease the incidence of child accidental injuries.

Furthermore, these study shows that the data obtained on a nuclear site could apply to a nearby nuclear site, with close agro-climatic conditions. The influence of the types of productions and the agricultural and breeding practices, on the potential contamination of foodstuffs produced locally in accidental situation, led the IRSN to develop summary sheets on the agricultural environment of the nuclear sites. These levels of contamination can be very different according to the period of the year in which occurs the accident. For example, the date of harvest determines if these products will be almost exempt from contamination (so already harvested) or if they will present a maximal contamination. In complement, these sheets give some local contacts which would allow obtaining contextual precision around sensitive dates. These data will also allow elaborating sampling strategies to monitor foodstuffs activities after an accidental release. Based on these knowledge of environmental characteristics and considering that the metrological capacity will be necessarily limited, the monitoring strategies must insure that all foodstuff produced on the whole monitored area are below intervention levels.

    情绪在决策领域中的引入曾历经过一个从刻意回避到日益重视的过程,大量研究表明,即使与决策本身无关的偶然情绪也会对人类的决策行为具有重要作用。本文通过梳理本领域的最新研究提出未来应注重考察:偶然情绪的影响条件、具体情绪的作用以及偶然情绪与可选项的情感属性对决策的交互影响。最后,本文在情绪激发方法、情绪的操纵检测和决策任务实测等方面进行了总结并提出一点研究建议。%The introduction of emotion into the research of decision making has come through the process from being intentionally neglected to being increasingly emphasized. Numerous studies demonstrate that accidental emotions that typically arise from factors external to the judgment about the decision being made have significant influences on the decision making. According to recent researches on the effect of incidental emotions on decision making, the present study proposed some implications for the future studies, that are, identifying moderating factors for carryover of incidental emotions, exploring the role of discrete emotions in decision making, and addressing the interaction effects between incidental emotions and the options’ emotional claims. Finally, the current study addressed some suggestions for the future study, such as, the induction technique of emotions, the measurement for manipulated emotions, and the way to apply different decision tasks.

  13. The accidental overexposures

    International Nuclear Information System (INIS)

    The radioisotope or ionizing radiation medical or industrial use may generate accidents where human beings are exposed to very high doses. The accident frequency is increasing quickly because of the industrial source use development. The accidents don't catch only the plant or hospital staffs but also public people. The serious accidents result from conception errors, bad installation maintenance, lack or not enough staff training, transgression of safety processes. The accidents happen in not very specialized firms. Those resulting from energy production reactors are very seldom except for Chernobyl or military submarines. In the medical or hospital installations, accidents may affect the staffs or the patients. Most of the accidents could have been avoided by the simple respect of the simple surety duties. The follow up and analysis of serious accidents can bring an effective collaboration to the prevention. 78 refs., 3 annexes., 14 tabs., 17 figs

    Quantitative characteristics of dissolved and particulate radiocesium wash-off from contaminated watersheds after the FDNPP accident are calculated based on published monitoring data. Comparative analysis is provided for radiocesium wash-off parameters and distribution coefficients, Kd, between suspended matter and water in rivers and surface runoff on Fukushima and Chernobyl contaminated areas for the first years after the accidents. It was found that radiocesium distribution coefficient in Fukushima rivers is essentially higher (1-2 orders of magnitude) than corresponding values for rivers and surface runoff within the Chernobyl zone. This can be associated with two factors: first, the high fraction of clays in the predominant soils and sediments of the Fukushima area and accordingly a higher value of the radiocesium Interception Potential, RIP, in general, and secondly the presence of water insoluble glassy particles containing radiocesium in the accidental fallout at Fukushima. It was found also that normalized dissolved wash-off coefficients for Fukushima catchments are 1-2 orders of magnitude lower than corresponding values for the Chernobyl zone. Normalized particulate wash-off coefficients are comparable for Fukushima and Chernobyl. Results of the investigation of radiocesium's ((134)Cs and (137)Cs) vertical distribution in soils of the close-in area of the Fukushima Dai-ichi NPP - Okuma town and floodplain of the Niida river are presented. The radiocesium migration in undisturbed forest and grassland soils at Fukushima contaminated area has been shown to be faster as compared to the Chernobyl 30-km zone during the first three years after the accidents. This may be associated with higher annual precipitation (by about 2.5 times) in Fukushima as compared to the Chernobyl zone, as well as the differences in the soil characteristics and temperature regime throughout a year.

    The European Commission Joint Research Centre (JRC) in Ispra (Italy) has long been running nuclear installations for research purposes. The Nuclear Decommissioning and Facilities Management Unit (NDFM) is responsible for the surveillance of radioactivity levels in nuclear emergency conditions. The NDFM Unit has commissioned the implementation of a specifically developed decision support system, which can be used for quick emergency evaluation in the case of hypothetical accident and for emergency exercises. The requisites were to be a user-friendly software, able to quickly calculate and display values of air and ground radioactive contamination in the complex area around JRC, following an accidental release of radioactive substances from a JRC nuclear research installation. The developed software, named 'SafeAirView', is an advanced implementation of GIS technology applied to an existing MS-DOS mode dispersion model, SAFE{sub A}IR (Simulation of Air pollution From Emissions{sub A}bove Inhomogeneous Regions). SAFE{sub A}IR is a numerical model which simulates transport, diffusion, and deposition of airborne pollutants emitted in the low atmosphere above complex orography at both local and regional scale, under non-stationary and inhomogeneous emission and meteorological conditions. SafeAirView makes use of user-friendly MS-Windows type interface which drives the dispersion model by a sequential and continuous input-output process, allowing a real time simulation. The GIS environment allows a direct interaction with the territory elements in which the simulation takes place, using data for the JRC Ispra region represented in geo-referenced cartography. Furthermore it offers the possibility to relate concentrations with population distribution and other geo-referenced maps, in a geographic view. Output concentration and deposition patterns can be plotted and/or exported. In spite of the selected specific databases, the SafeAirView software architecture is a

  19. Application of the Alkaline Comet Assay and the Analysis of Structural Chromosome Aberrations in Assessment of Genetic Damage After Accidental Exposure to Ionising Radiation

    International Nuclear Information System (INIS)

    Full text: Living with the effects of low-level ionising radiation is one of the normal hazards of life. However, the effects of lower doses may not show up for years after exposure and are due to various changes in DNA molecules and chromosomes. Radiation-induced mutations seem to be brought about by the deletion of small pieces of chromosomes during the process of chromosome breakage and repair. Since chromosome damage is most likely to happen in dividing cells, ionising radiation usually cause cancer in those parts of the body where cells are actively dividing. Ionising radiation kills rapidly dividing cells, blood lymphocytes among them. People are exposed to high doses of ionising radiation when radiation accidents occur. The cytogenetical consequences of accidental exposure to gamma-radiation (radiation dose 221 mSv) were investigated by using alkaline Comet assay and the analysis of structural chromosomal aberrations (CA). Blood samples were repeatedly collected during one-year period after the accident. By using the Comet assay immediately after accidental exposure a high level of DNA damage was recorded. Although this level was decreasing over a one-year period, it was still elevated compared to normal values of DNA damage for unexposed persons. Immediately after the accident prevalence of CA (dicentrics, acentrics) over chromatid aberrations was recorded. However, one year afterwards only a few chromatid breaks were recorded. Our results confirmed usefulness of the alkaline Comet assay as a simple and sensitive technique for the biomonitoring of DNA damages, especially in the cases of accidental exposure to ionising radiation.

    Full Text Available The personality traits that mediate risky driving and accidents among university students drivers were investigated. Study 1 (N=132 tested for the relation between risky behaviors and personality (16PF-5 second order dimensions. Three factors were extracted concerning risky driving: driving errors of commission, distraction, and driving errors of omission. Individuals with low self-control and high levels of anxiety were more prone to commit distractive behavior and driving errors of omission. Low self-control and high independence levels were associated with driving errors of commission. In study 2 (N=540, we tested if the number of road accidents for which an individual has been responsible was related to risky driving behavior. Drivers who committed more accidents presented higher scores in three new risky driving factors obtained: reckless driving, impaired concentration and division of attention.

    International Nuclear Information System (INIS)

    This approach to a return on experience of the post-accidental management of the Chernobyl accident identified four main steps: the passage from an accidental phase to a post-accidental phase from 1986 to 1991 (implementation of countermeasures, design of a radiological protection), the setting of an institutional and legal framework for the post-accidental management from 1991 to 1993 (compensations, definition of standards for food production and consumption, psychological support of populations), the search for alternative strategies from 1993 to 2001, and a sustainable rehabilitation of living conditions in contaminated territories between 2001 and 2006. Based on the return on experience on this various issues, the authors draw a set of lessons and give recommendations. They notably address the characteristics of a situation of durable radiological contamination, the role of standards in the response to a post-accidental situation, the role of expertise and knowledge building, the role and action of public authorities, the progressive building up of a local response to the crisis, the preparedness to a situation of durable contamination

    This study presents the results of atmosphere dispersion modeling using CALPUFF code that are based on computational simulation to evaluate the environmental characteristics of the Barakah nuclear power plant (BNPP) in west area of UAE. According to meteorological data analysis (2012~2013), the winds from the north(7.68%) and west(9.05%) including NNW(41.63%), NW(28.55%), and WNW(6.31%) winds accounted for more than 90% of the wind directions. East(0.2%) and south(0.6%) direction wind, including ESE(0.31%), SE(0.38%), and SSE(0.38%) were rarely distributed during the simulation period. Seasonal effects were not showed. However, a discrepancy in the tendency between daytime and night-time was observed. Approximately 87% of the wind speed was distributed below 5.4m/s (17%, 47% and 23% between the speeds of 0.5-1.8m/s 1.8-3.3m/s and 3.3-5.4m/s, respectively) during the annual period. Seasonal wind speed distribution results presented very similar pattern of annual distribution. Wind speed distribution of day and night, on the other hand, had a discrepancy with annual modeling results than seasonal distribution in some sections. The results for high wind speed (more than 10.8m/s) showed that this wind blew from the west. This high wind speed is known locally as the 'Shamal', which occurs rarely, lasting one or two days with the strongest winds experienced in association with gust fronts and thunderstorms. Six variations of cesium-137 (137Cs) dispersion test were simulated under hypothetic severe accidental condition. The 137Cs dispersion was strongly influenced by the direction and speed of the main wind. From the test cases, east-south area of the BNPP site was mainly influenced by 137Cs dispersion. A virtual receptor was set and calculated for observation of the 137Cs movement and accumulation. Surface roughness tests were performed for the analysis of topographic conditions. According to the surface condition, there are various surface roughness length. Four types

    Full Text Available Introducción: Describimos un momento crucial del itinerario vital de los amputados traumáticos. Objetivos: Describir y analizar las perspectivas elaboradas en torno al instante del accidente desde el punto de vista de los amputados traumáticos. Metodología: Estudio cualitativo de corte etnográfico. Participantes del estudio: 19 amputados en su mayor parte de origen traumático. Los datos se recogieron mediante entrevistas semiestructuradas, historias de vida y observación participante. Resultados: Aparece el concepto de "ser invulnerable", la imprevisibilidad de los accidentes y el papel de la casualidad y el azar en la tragedia. El arcaico debate del destino frente a la casualidad está presente. Conclusiones: Muchos moteros, con un estilo de vida ligado al ocio, experimentan el frenazo que supone el suceso, metafóricamente, de 100 a 0 km/h. Se evidencia la impronta en el imaginario de los amputados del poder de la ciencia encarnada en la cirugía y la inmortalidad del cuerpo como concepto.

    Full Text Available En España se han puesto en marcha diferentes medidas de intervención con el objeto de modificar la práctica de los conductores de vehículos de motor, sin embargo no se ha observado una tendencia descendente ni en la tasa de accidentes de tráfico ni en el número de víctimas relacionadas con los mismos. Este articulo se plantea el interrogante de si las medidas tomadas para reducir el número de víctimas por accidente de tráfico se han dirigido realmente hacia las causas responsables de esa tendencia. Utilizando diversas fuentes de datos se observa que en España al comienzo de los años noventa se produjo una importante reducción de la tasa de accidentes de tráfico y sus consecuencias, pero en la segunda mitad de la misma década el incremento en la tasa de lesiones por accidentes de tráfico fue similar al producido en los años ochenta. Igualmente se observa que desde 1980 el consumo per capita de alcohol ha mostrado una tendencia descendente y que el número de lesiones por accidente de tráfico durante los últimos vente años ha estado fuertemente asociado al ciclo económico. Se concluye señalando que las medidas para el control de este problema en España se han centrado principalmente en la modificación de la conducta que incrementa el riesgo y severidad de las lesiones por accidente de tráfico, pero se han ignorado los determinantes macroeconómicos que explican la tendencia de la frecuencia de este problema de salud.

  4. Rapid assessment of accidental exposures (RACE) in environment using ultra-sensitive LiF:Mg,Cu,P (MCP-N) thermoluminescent detectors

    International Nuclear Information System (INIS)

    The main goal of this work is to demonstrate a concept and first results of a new system for Rapid Assessment of Accidental Exposures (RACE) which is based on a new generation of ultra sensitive thermoluminescent detectors LiF:Mg, Cu, P. The RACE system is envisaged to be able to monitor environmental radiation doses at a large number of locations within a few days. The RACE will further be able to work as a standard detector system for routine environmental monitoring, but the major innovation is its capability to perform a rapid, short-term (ca. 24-48 hours) in situ dose assessment in case of any type of nuclear accidents, radiocontamination of environment or restoration works.

    A mathematical model was constructed for the purpose of predicting the fraction of human population which would die within 1 year of an accidental exposure to airborne radionuclides. The model is based on data from laboratory experiments with rats, dogs and baboons, and from human epidemiological data. Doses from external, whole-body irradiation and from inhaled, alpha- and beta-emitting radionuclides are calculated for several organs. The probabilities of death from radiation pneumonitis and from bone marrow irradiation are predicted from doses accumulated within 30 days of exposure to the radioactive aerosol. The model is compared with existing similar models under hypothetical exposure conditions. Suggestions for further experiments with inhaled radionuclides are included. 25 refs., 16 figs., 13 tabs.

    This document describes the method used in the SAFRAN tool for the calculation of exposure arising from accidental release of airborne radioactive materials. Models can be used for evaluation of occupational exposure to allow comparison with the relevant dose limiting criteria. Presently, four models are available to address different exposure conditions. The first three are ‘no dilution’ model, ‘gradual mixing’ model and ‘complete mixing’ model. The fourth combined ‘gradual mixing / complete mixing’ model is a combination of the two last models and allows the user to run subsequently the ‘gradual mixing and ‘complete mixing’ models. Each of the models are created using Ecolego. Each of the models is described and their practical use is explained

    Full Text Available A novel family of exactly solvable quantum systems on curved space is presented. The family is the quantum version of the classical Perlick family, which comprises all maximally superintegrable 3-dimensional Hamiltonian systems with spherical symmetry. The high number of symmetries (both geometrical and dynamical exhibited by the classical systems has a counterpart in the accidental degeneracy in the spectrum of the quantum systems. This family of quantum problem is completely solved with the techniques of the SUSYQM (supersymmetric quantum mechanics. We also analyze in detail the ordering problem arising in the quantization of the kinetic term of the classical Hamiltonian, stressing the link existing between two physically meaningful quantizations: the geometrical quantization and the position dependent mass quantization.

    The present study examines onboard thermal microclimatic conditions and thermoregulation of pullets exposed to accidental hypothermia during wet-cold weather transportation conditions, and the effect of rewarming on colonic temperature (CT) of the birds immediately after transportation. A total of 2200 pullets were transportation for 5 h in two separate vehicles during the nighttime. The last 3 h of the transportation period was characterized by heavy rainfall. During the precipitation period, each vehicle was covered one fourth way from the top-roof with a tarpaulin. The onboard thermal conditions inside the vehicles during transportation, which comprised ambient temperature and relative humidity were recorded, while humidity ratio and specific enthalpy were calculated. The CT of the birds was recorded before and after transportation. During transportation, onboard thermal heterogeneity was observed inside the vehicles with higher (p < 0.05) values in the front and center, and lower values recorded at the air inlets at the sides and rear planes. The CT values recorded in birds at the front and center planes were between 42.2 and 42.5 °C, indicative of mild hypothermia; while lower CT values between 28 and 38 °C were recorded at the sides and rear planes, indicative of mild to severe hypothermia. Several hours of gradual rewarming returned the CT to normal range. The result, for the first time, demonstrated the occurrence of accidental hypothermia in transported pullets under tropical conditions and a successful rewarming outcome. In conclusion, transportation of pullets during wet weather at onboard temperature of 18-20 °C induced hypothermia on birds located at the air inlets, which recovered fully after several hours of gradual rewarming.

  11. Development of AI (Artificial Intelligence)-based simulation system for man-machine system behavior in accidental situations of nuclear power plant

    International Nuclear Information System (INIS)

    A prototype version of a computer simulation system named JACOS (JAeri COgnitive Simulation system) has been developed at JAERI (Japan Atomic Energy Research Institute) to simulate the man-machine system behavior in which both the cognitive behavior of a human operator and the plant behavior affect each other. The objectives of this system development is to provide man-machine system analysts with detailed information on the cognitive process of an operator and the plant behavior affected by operator's actions in accidental situations of an NPP (nuclear power plant). The simulation system consists of an operator model and a plant model which are coupled dynamically. The operator model simulates an operator's cognitive behavior in accidental situations based on the decision ladder model of Rasmussen, and is implemented using the AI-techniques of the distributed cooperative inference method with the so-called blackboard architecture. Rule-based behavior is simulated using knowledge representation with If-Then type of rules. Knowledge-based behavior is simulated using knowledge representation with MFM (Multilevel Flow Modeling) and qualitative reasoning method. Cognitive characteristics of attentional narrowing, limitation of short-term memory, and knowledge recalling from long-term memory are also modeled. The plant model of a 3-loop PWR is also developed using a best estimate thermal-hydraulic analysis code RELAP5/MOD2. Some simulations of incidents were performed to verify the human model. It was found that AI-techniques used in the human model are suitable to simulate the operator's cognitive behavior in an NPP accident. The models of cognitive characteristics were investigated in the effects on simulated results of cognitive behaviors. (author)

  12. Simulation of equivalent dose due to accidental electron beam loss in Indus-1 and Indus-2 synchrotron radiation sources using FLUKA code

    International Nuclear Information System (INIS)

    Indus-1 and Indus-2 are two Synchrotron radiation sources at Raja Ramanna Centre for Advanced Technology (RRCAT), India. Stored electron energy in Indus-1 and Indus-2 are 450MeV and 2.5GeV respectively. During operation of storage ring, accidental electron beam loss may occur in addition to normal beam losses. The Bremsstrahlung radiation produced due to the beam losses creates a major radiation hazard in these high energy electron accelerators. FLUKA, the Monte Carlo radiation transport code is used to simulate the accidental beam loss. The simulation was carried out to estimate the equivalent dose likely to be received by a trapped person closer to the storage ring. Depth dose profile in water phantom for 450MeV and 2.5GeV electron beam is generated, from which percentage energy absorbed in 30cm water phantom (analogous to human body) is calculated. The simulation showed the percentage energy deposition in the phantom is about 19% for 450MeV electron and 4.3% for 2.5GeV electron. The dose build up factor in 30cm water phantom for 450MeV and 2.5GeV electron beam are found to be 1.85 and 2.94 respectively. Based on the depth dose profile, dose equivalent index of 0.026Sv and 1.08Sv are likely to be received by the trapped person near the storage ring in Indus-1 and Indus-2 respectively. (author)

  14. Personnel Dosimetry for Radiation Accidents. Proceedings of a Symposium on Personnel Dosimetry for Accidental High-Level Exposure to External and Internal Radiation

    International Nuclear Information System (INIS)

    Accidents involving the exposure of persons to high levels of radiation have been few in number and meticulous precautions are taken in an effort to maintain this good record. When, however, such an accident does occur, a timely estimate of the dose received can be of considerable help to the physician in deciding whether a particular person requires medical treatment, and in selecting the most appropriate treatment. Individual dosimetry provides the physical basis for relating the observed effects to those in other accident cases, to other human data, and to data from animal experiments, thus providing an important aid to rational treatment and to the accumulation of a meaningful body of knowledge on the subject. It is most important therefore that, where there is a possibility of receiving high-level exposure, methods of personnel dosimetry should be available that would provide the dosimetric information most useful to the physician. Provision of good personnel dosimetry for accidental high-level exposure is in many cases an essential part of emergency planning because the information provided may influence emergency and rescue operations, and can lead to improved accident preparedness. Accordingly, the International Atomic Energy Agency and the World Health Organization jointly organized the Symposium on Personnel Dosimetry for Accidental High-Level Exposure to External and Internal Radiation for the discussion of such methods and for a critical review of the procedures adopted in some of the radiation accidents that have already occurred. The meeting was attended by 179 participants from 34 countries and from five other international organizations. The papers presented and the ensuing discussions are published in these Proceedings. It is hoped that the Proceedings will be of help to those concerned with the organization and development of wide-range personnel monitoring systems, and with the interpretation of the results provided

Esta entidad es el resultado de la deficiencia de a-galactosidasa A, lo que resulta en depósito patológico de glicoesfingilípidos en distintas poblaciones celulares. Asociados a la insuficiencia renal y cardíaca, los accidentes cerebrovasculares pueden derivar en la muerte de los pacientes. Durante mucho tiempo el único mecanismo generador de daño vascular informado fue la oclusión vascular por depósito lipídico a nivel endotelial. En la actualidad se describen otros mecanismos. El advenimiento de la terapia de reemplazo enzimático ha generado gran expectativa en cuanto la posibilidad de reversión de estos mecanismos. Si bien la evidencia es escasa y son necesarios más estudios a largo plazo, algunos informes demuestran que luego de meses, el tratamiento ha logrado revertir algunos de los mecanismos implicados.The objective is to analyze the updated evidence on the physiopathological mechanisms that can generate cerebrovascular damage in Fabry disease. Fabry disease is the result of the deficiency of a-galactosidasa A, which causes pathological storage of glycosphingolipids, in different cells. Associated to renal and cardiac insufficiency, cerebrovascular complications can derive in the death of the patients. During a long time the only reported mechanism was the vascular occlusion by deposit of lipids at endothelial level. At the present time, other mechanisms are postulated. The arrival of enzyme replacement therapy has generated great expectation on the possibility of reversion of these alterations. Although the evidence is scarce and more long term studies are necessary, some reports demonstrate that after months, the treatment has managed to revert some of the mechanisms involved.

  16. A simulation study of dispersion of air borne radionuclides from a nuclear power plant under a hypothetical accidental scenario at a tropical coastal site

    Science.gov (United States)

    Srinivas, C. V.; Venkatesan, R.

    Meteorological condition in coastal regions is diurnally variable and spatially heterogeneous due to complex topography, land-sea interface, etc. A wide range of dispersion conditions is possible on a given day in the coastal regions. In case of inadvertent accidental situations, though unlikely, it would be necessary to examine the potentially severe case among different dynamically occurring local atmospheric conditions for dispersion and its range of impact around a nuclear power plant for safety analysis. In this context, dispersion of air borne radioactive effluents during a hypothetical accidental scenario from a proposed prototype fast breeder reactor (PFBR) at an Indian coastal site, Kalpakkam, is simulated using a 3-D meso-scale atmospheric model MM5 and a random walk particle dispersion model FLEXPART. A simulation carried out for a typical summer day predicted the development of land-sea breeze circulation and thermal internal boundary layer (TIBL) formation, which have been confirmed by meteorological observations. Analysis of dose distribution shows that the maximum dose for releases from a 100 m stack occurs at two places within 4 km distance during sea breeze/TIBL fumigation hours. Maximum dose also occurred during nighttime stable conditions. Results indicate that, on the day of present study, the highest concentrations occurred during periods of TIBL fumigation rather than during stable atmospheric conditions. Further, the area of impact (plume width at the surface) spreads up to a down wind distance of 4 km during fumigation condition. Simulation over a range of 25 km has shown turning of plume at the incidence of sea breeze circulation and two different dispersion patterns across the sea breeze front. These results are significant in comparison to the expected pattern shown by Gaussian plume model used for routine analysis.

  17. Accidental nuclear war: Modifications to superpower arsenals and to procedures for handling them could substantially reduce the risk of unintended Armageddon

    If nuclear war breaks out in the coming decade or two, it will probably be by accident. The threat of a cold-blooded, calculated first strike is vanishing, but beneath the calm surface of constructive diplomacy among the traditional nuclear rivals lurks the danger of unpremeditated use of nuclear weapons. The accidental, unauthorized or inadvertent use of these weapons has become the most plausible path to nuclear war. Both superpowers, as well as France, Great Britain and China - long-standing members of the nuclear club - are potential sources of accidental missile launch. The emergence of fledgling nuclear powers such as India, Pakistan and Israel - some armed with ballistic missiles - pushes nuclear safeguards even closer to the top of the international security agenda. The chances of unwanted nuclear war would be reduced significantly if tamper proof, coded locks were installed on all nuclear weapons and if methods were put in place to disarm nuclear forces even after launch. In addition, the US and the Soviet Union should reduce their reliance on the dangerous policy of launch on warning and reduce the launch readiness of their nuclear forces. The social and political upheavals in the Soviet Union underscore fears of unintended nuclear war. Civil turmoil raises the possibility that rebellious ethnic groups or splinter organizations could capture nuclear weapons. Other, deeper fault lines run through the whole of Soviet society and may be capable of cracking the foundations of its nuclear command system. Although the US faces no such civil unrest, the country's system of nuclear command carries some risk that nuclear weapons might be used contrary to the intentions of legitimate authorities.

  18. Historical Doses from Tritiated Water and Tritiated Hydrogen Gas Released to the Atmosphere from Lawrence Livermore National Laboratory (LLNL). Part 5. Accidental Releases

    Energy Technology Data Exchange (ETDEWEB)

    Peterson, S

    2007-08-15

    Over the course of fifty-three years, LLNL had six acute releases of tritiated hydrogen gas (HT) and one acute release of tritiated water vapor (HTO) that were too large relative to the annual releases to be included as part of the annual releases from normal operations detailed in Parts 3 and 4 of the Tritium Dose Reconstruction (TDR). Sandia National Laboratories/California (SNL/CA) had one such release of HT and one of HTO. Doses to the maximally exposed individual (MEI) for these accidents have been modeled using an equation derived from the time-dependent tritium model, UFOTRI, and parameter values based on expert judgment. All of these acute releases are described in this report. Doses that could not have been exceeded from the large HT releases of 1965 and 1970 were calculated to be 43 {micro}Sv (4.3 mrem) and 120 {micro}Sv (12 mrem) to an adult, respectively. Two published sets of dose predictions for the accidental HT release in 1970 are compared with the dose predictions of this TDR. The highest predicted dose was for an acute release of HTO in 1954. For this release, the dose that could not have been exceeded was estimated to have been 2 mSv (200 mrem), although, because of the high uncertainty about the predictions, the likely dose may have been as low as 360 {micro}Sv (36 mrem) or less. The estimated maximum exposures from the accidental releases were such that no adverse health effects would be expected. Appendix A lists all accidents and large routine puff releases that have occurred at LLNL and SNL/CA between 1953 and 2005. Appendix B describes the processes unique to tritium that must be modeled after an acute release, some of the time-dependent tritium models being used today, and the results of tests of these models.

    Objective To explore the characteristics of accidental death in infants and children under 5 years of age. Methods A total of 359 accidental death cases occurred between Oct 1st, 2003 and Sep 30th, 2010, in infants and children under 5 years of age in Lishui, Zhejiang. The data of accidents were collected and investigated. Results Accidental death accounted for 20.34% of all death cases for the population. The rate of annual accidental death was 2. 32‰ on average, which decreased from 2. 36‰ in 2004 to 1. 83‰ in 2010.However, the proportion of accidental death increased from 16. 62% to 20.22% during the period. The incidence and mortality rates of accidental injuries were slightly higher in rural areas than in urban areas (P< 0.01). The mortality rate of accidental injuries was higher in boys (12. 22‰) than in girls (10.54‰) (P<0.01). The three leading causes of injury death were accidental suffocation, drowning and traffic accident. Of the accidental death cases in infants and children under 5 years of age, 35. 65% were under one year of age, 20.61% aged 1 year, 17. 27% aged 2 years, 13. 93% aged 3 years and 12. 53% aged 4 years.

  6. Experiments in support to the understanding of fuel cladding behavior in normal, accidental and storage conditions at the CEA LECI hotlab facility

    International Nuclear Information System (INIS)

    This paper presents the experimental capabilities dedicated to the characterization of fuel cladding material behaviour in normal, accidental and storage conditions of the CEA Saclay LECI hotlab facility. The main objective of the LECI facility, that operates 45 hotcells, is to provide metallurgical, mechanical and physico-chemical data on irradiated materials (from fuel assembly, core structure, and vessel) in support to the operation of light water reactors as well as the development of future nuclear systems. Specifically, a comprehensive review of the available equipment which can be used to characterize a broad range of properties of irradiated cladding materials for Gen2 and 3 nuclear applications is presented. These data are then used to identify normal, accidental or storage conditions behaviour laws and models able to predict the in-service lifetime of the materials. The mechanical properties of irradiated zirconium alloy cladding are characterized through a complete set of mechanical testing such as tensile, creep and burst tests. Specific experiments have been developed in order to obtain the mechanical properties in axial, circumferential and biaxial conditions, or to simulate LOCA or RIA transients. Fine metrology tools give access to dimensional variations at the μm scale after various irradiation experiments performed in MTR, that address creep and growth under irradiation. State-of the-art equipment, including optical microscopy with image analysis for hydride content and distribution (HydruroTM), FEG-Scanning Electron Microscopy fitted with EDS, WDS and EBSD, Transmission Electron Microscopy, Electron Probe MicroAnalysis, hydrogen global measurement, and Nuclear Reaction Analysis, allow the characterization of key parameters to address the cladding behavior: precipitate phase evolution and nucleation and growth of irradiation defects, hydrogen precipitation and reorientation, structure and microstructure of oxide layers formed, fracture mode after

    The new fuel designs for operation cycles more long have regions of uncertainty bigger that those of the old fuels, and therefore, they can have oscillations of power when an event is presented that causes that the reactor operates to high power and low flow of coolant. During the start up of the reactor there are continued procedures that avoid that oscillations are presented with that which makes sure the stable behavior of the reactor. However, when the reactor is operating to nominal conditions and they are shot or they are transferred to low speed the recirculation pumps, it cannot make sure that the reactor doesn't present oscillations of power when entering to the restricted operation regions. The methods of stability analysis commonly use signs of neutronic noise that require to be stationary, but after a transitory one where they commonly get lost the recirculation pumps the signs they don't have the required characteristics, for what they are used with certain level of uncertainty by the limited validity of the models. In this work the Prony method is used to determine the reactor stability, starting from signs of transitory and it is compared with autoregressive models. Four events are analyzed happened in the Laguna Verde power plant where the reactor was in the area of high power and low flow of coolant, giving satisfactory results. (Author)

  8. Optimizing bone surveys performed for suspected non-accidental trauma with attention to maximizing diagnostic yield while minimizing radiation exposure: utility of pelvic and lateral radiographs

    International Nuclear Information System (INIS)

    Skeletal surveys for non-accidental trauma (NAT) include lateral spinal and pelvic views, which have a significant radiation dose. To determine whether pelvic and lateral spinal radiographs should routinely be performed during initial bone surveys for suspected NAT. The radiology database was queried for the period May 2005 to May 2011 using CPT codes for skeletal surveys for suspected NAT. Studies performed for skeletal dysplasia and follow-up surveys were excluded. Initial skeletal surveys were reviewed to identify fractures present, including those identified only on lateral spinal and/or pelvic radiographs. Clinical information and MR imaging was reviewed for the single patient with vertebral compression deformities. Of the 530 children, 223 (42.1%) had rib and extremity fractures suspicious for NAT. No fractures were identified solely on pelvic radiographs. Only one child (<0.2%) had vertebral compression deformities identified on a lateral spinal radiograph. This infant had rib and extremity fractures and was clinically paraplegic. MR imaging confirmed the vertebral body fractures. Since no fractures were identified solely on pelvic radiographs and on lateral spinal radiographs in children without evidence of NAT, nor in nearly all with evidence of NAT, inclusion of these views in the initial evaluation of children for suspected NAT may not be warranted.

  9. User Guide ECOREA-RICE (version 1.0). Program for assessing the transfer of radionuclides released accidentally onto flooded rice-fields

    International Nuclear Information System (INIS)

    The computer code ECOREA-RICE is a dynamic compartment model that is specially designed for estimating the transfer of radionuclides deposited onto flooded rice-fields after an accidental release. The model consists of six independent compartments including rice-body, grain, surface water, root-zone soil, fixed soil and deep soil, and takes into account the transfer processes including radioactive decay, percolation, leaching, shoot-base absorption, root-uptake, weathering, translocation, fixation in soil by adsorption and desorption, and soil-mixing by plowing. The rate of the change of radioactivity in compartments is expressed by a set of the first order ordinary differential equations, which are solved by the fourth order Runge-Kutta algorithm. Input to the program includes the deposition date, transplanting date, ear emergence date, harvest date, soil data, the biomass data of rice-plant, and rate constants associated with transfer processes. Output includes the list of input data, the activity of radionuclides in compartment, the rate constant, and the transfer factor of rice-body and grain with time

  10. The radiological consequences of notional accidental releases of radioactivity from fast breeder reactors: sensitivity to the dose-effect relationships adopted for early biological effects

    International Nuclear Information System (INIS)

    This study considered the sensitivity to the dose-response relationships adopted for the estimation of early biological effects from notional accidental releases of radioactivity from fast breeder reactors. Two distinct aspects were considered: the sensitivity of the predicted consequences to variation in the dose-mortality relationships for irradiation of the bone marrow and the lung; and the influence of simple supportive medical treatment in reducing the incidence of early deaths in the exposed population. The numbers of early effects estimated in the initial study were relatively insensitive to variation in the dose-mortality relationships within the bounds proposed. The few exceptions concerned releases of particular nuclide composition, and the variation in the predicted consequences could be around an order of magnitude; the absolute numbers of effects however were in general small when the sensitivity was most pronounced. The reduction in the incidence of early deaths when using simple supportive treatment varied markedly with the nuclide composition of the release. Areas of uncertainty were identified where further research and investigation might most profitably be directed with a view to improving the reliability of the dose-effect relationships adopted and hence of the predicted consequences of the release considered.

    Prussian blue (i.e., iron[III] hexacyanoferrate[II], PB) has been synthesized by reaction of iron(III) chloride with potassium hexacyanoferrate and further immobilized in chitosan sponge (cellulose fibers were added in some samples to evaluate their impact on mechanical resistance). The composite was finally re-acetylated to produce a chitin-PB sponge. Experimental conditions such as the freezing temperature, the content of PB, the concentration of the biopolymer and the presence of cellulose fibers have been varied in order to evaluate their effect on the porous structure of the sponge, its water absorption properties and finally its use for cesium(I) recovery. The concept developed with this system consists in the absorption of contaminated water by the composite sponge, the in situ binding of target metal on Prussian blue load and the centrifugation of the material to remove treated water from soaked sponge. This material is supposed to be useful for the fast treatment of accidental dumping of Cs-contaminated water. PMID:25646900

    This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models to simulation of tritium dispersion caused by an accident in a Candu reactor located in the ongoing Angra 3 site. The Candu reactor is one that uses heavy water (D{sub 2}O) as moderator and coolant of the core. It was postulated, then, the LOCA accident (without fusion), where was lost 66 m3 of soda almost instantaneously. This inventory contained 35 P Bq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios (plant stopped or operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1 MBq/m{sup 3}) during the first 14 days after the accident.

    Full Text Available OBJECTIVES: understand the Social Representations about needlestick injuries elaborated by Nursing Technicians and analyze how these representations influence their conducts. METHOD: the data, obtained by interviews, were processed using ALCESTE software and their analysis was based on Serge Moscovici's Social Representations Theory. RESULTS: it was evidenced that, after the accident, these professionals take care of the affected area. Then, they report the accident, motivated by the fear of catching HIV and hepatitis. The different feelings experienced are due to this fear and the way they were forwarded by the institution, reflecting in the cause they attribute to their accident. CONCLUSIONS: it was verified that knowledge about the accident as a whole is very incipient in this professional group, demanding continuing education and greater emphasis on this subject in professional training. It is expected that this study draws public authorities and health institutions' attention to the problem and that it modifies Nursing Technicians' Social Representations about percutaneous exposure.OBJETIVOS: Comprender las Representaciones Sociales de los accidentes con materiales corto-punzantes, elaboradas por Técnicos de Enfermería, así como analizar de que modo esas representaciones influencian las conductas de eses profesionales.

    The aim of our study was to assess the aerobic biodegradation of four selected sulfonamides (sulfanilamide, sulfamethoxazole, sulfadiazine and sulfathiazole) using water samples drawn from highly polluted rivers. Additionally, we aimed to identify the factors that have a significant effect on the process efficiency. The 19 water samples were collected from Brynica and Czarna Przemsza rivers (in Poland) at the same location at approximately monthly intervals. A characteristic feature of the results is the presence of significant differences between the rates of sulfonamides biodegradation in particular samples. The sulfonamide most resistant to biodegradation was sulfamethoxazole, whereas sulfathiazole was most biodegradable. Seasonal variations and related microbial population changes had the most significant effects on sulfonamides biodegradation, e.g., the studied process was highly inhibited during wintertime. A decrease in the biodegradation rate in the river water could be caused by an accidental water pollution by industrial wastewater with heavy metals, an increase in salinity and a decrease in pH, and turbidity.

  17. The contribution of the CSNI Principal Working Group on Confinement of Accidental Radioactive Releases to the technical consensus and spreading of knowledge on severe accidents

    International Nuclear Information System (INIS)

    The Nuclear Energy Agency (NEA) Committee on the Safety of Nuclear Installations (CSNI) is an international committee made up of scientists and engineers. It was set up 1973 to develop and co-ordinate the activities of the NEA concerning the technical aspects of the design, construction and operation of nuclear installations insofar as they affect the safety of such installations. The Committee's purpose is to foster international cooperation in nuclear safety amongst the Member countries. Five Principal Working Groups (PWG) operate under the leadership of CSNI. PWG4 is named 'Confinement of Accidental Radioactive Releases' and its main activities are State of the Art Reports, International Standard Problem exercises, Specialist Meetings and Technical Opinion Papers. Together with other groups of experts involved in severe accident work, PWG4 has strongly contributed to the understanding of phenomena and the development of the knowledge base in that area, to the resolution of technical issues, and to the dissemination of the results. Taking examples from the products of the work of PWG4, the paper shows how this working group fosters international co-operation in the area of severe accidents and their management, and contributes to the development of a technical consensus.

    Highlights: • Prussian blue microparticles incorporated in chitin sponges. • Efficient Cs(I) sorption after water absorption by dry hybrid sponge. • Water draining after sorption for metal confinement and water decontamination. • High decontamination factors and distribution coefficients for Cs(I) and {sup 137}Cs(I). • Effect of freezing conditions on porous structure and textural characterization. - Abstract: Prussian blue (i.e., iron[III] hexacyanoferrate[II], PB) has been synthesized by reaction of iron(III) chloride with potassium hexacyanoferrate and further immobilized in chitosan sponge (cellulose fibers were added in some samples to evaluate their impact on mechanical resistance). The composite was finally re-acetylated to produce a chitin-PB sponge. Experimental conditions such as the freezing temperature, the content of PB, the concentration of the biopolymer and the presence of cellulose fibers have been varied in order to evaluate their effect on the porous structure of the sponge, its water absorption properties and finally its use for cesium(I) recovery. The concept developed with this system consists in the absorption of contaminated water by the composite sponge, the in situ binding of target metal on Prussian blue load and the centrifugation of the material to remove treated water from soaked sponge. This material is supposed to be useful for the fast treatment of accidental dumping of Cs-contaminated water.

    When a serious nuclear accident occurs, the radioisotopes of caesium are very worrying to public health. Because of their long environmental persistence, their diffusion and their solubility in natural environments, they are present in many foodstuffs. Numerous studies were undertaken during the atmospheric nuclear tests, but since the accident of Tchernobyl land Goiania, this research has been pursued anew. By using the experimental data,, this report takes stock of the knowledge on the metabolic transit of radiocaesium in domestic animals. The transfer of this radionuclide in the major foodstuffs of animal origin (milk, meat, eggs) is important and depends on the metabolism of the animal species, and in one species, the age, the physiologic state and the diet. Nevertheless, it is possible to restrict the radioactive contamination by adding to all animal feed, some additives. The methods for in vivo determination of the radioactive measurements in cattle, in laboratory or in real conditions, are discussed too. Finally, all these results are used to consider the short-, middle- and long-term management of an accidental situation. (authors)

  20. Liquid pathway generic study. Impacts of accidental radioactive releases to the hydrosphere from floating and land-based nuclear power plants

    International Nuclear Information System (INIS)

    The staff concludes that for representative sites, there are differences in the impacts of accidental radioactive releases to the hydrosphere between floating nuclear plants (FNPs) and land-based plants (LBPs) of the ice-condenser type. The consequences of releases from design basis accidents are found to be lower for an FNP than for an LBP. For core-melt events which we consider to be of very low probability, the staff results indicate that the expected liquid pathway consequences are higher at an FNP than at an LBP, and that interdiction at the site is not likely for an FNP. The staff considers this combination of differences in release magnitude and interdiction potential to be significant. An assessment of the overall significance of the total risk associated with potential releases to liquid and airborne pathways will be considered in a forthcoming environmental impact statement for the FNP. This environmental impact statement will include a consideration of the environmental, social, and economic impacts of the operation of the FNP, as well as a value-impact analysis of alternatives which may avoid or mitigate radiological impacts to the environment
