    For a better NPP operation fuel behavior in accidental conditions (LOCA) is of great interest. Irradiation tests in ACPR can give interesting data on the CANDU fuel behavior in such kind of accidents. These data can be used for simulation, calibration and validation of fuel computer codes. The tests were accomplished in the TRIGA Annular Core Pulse Reactor (ACPR). Reactivity insertion accidents are not specific for the CANDU reactors but this type of test can contribute to a better understanding of CANDU type fuel behavior during various conditions.The tests were accomplished in the ambient pressure and temperature with fresh fuel probes. These tests gave similar results on the clad-fuel, and clad-coolant interactions which occur in LOCA accidents. The tests will be continued with instrumentation improvements what will give better statistics and information on fuel behavior in accident conditions. The structure of the paper is the following: - 1. Introduction; - 2. Irradiation device description; - 2.1. Capsule main parameters; - 2.1.1. Initial conditions; - 2.1.2. Test conditions; - 3. Tests objectives; - 4. Test of fuel; - 5. Results; - 5.1. Temperature effects; - 5.2. Pressure effects; - 6. Conclusion

    The thesis aims to study and simulate the mechanical behavior under Reactivity Initiated Accident loading conditions, of the Zircaloy 4 fuel claddings, irradiated or not. It also aims to characterize and simulate the behavior and the fracture under RIA loading conditions of hydrided Zircaloy 4 non irradiated. This study proposes an experimental approach and a simulation. (A.L.B.)

  3. Mechanical behaviour and failure of fuel cladding zirconium alloys in nuclear power plants under accidental RIA-type situation

    In French Nuclear Pressurized Water Reactors (PWRs), most of structural parts of the fuel assembly consist of zirconium alloy tubes and plates. Optimizing the management of fuel in nuclear power plants led to the increase in the duration of fuel cycles and power. The use of high fuel burnups requires drastic changes in the rules for reactor design in the nuclear safety. The evaluation of nuclear reactors in accident situations is based on reference accident scenarios. One of these hypothetical accidents, examined in this study, is the 'Reactivity Initiated Accident'. In order to assess the structural integrity of these parts it is necessary to characterize both the plastic flow and fracture behaviour of the materials at various stages of the life cycle, (i.e. at increasing levels of hydriding, irradiation, oxidation or thermal mechanical loading). The purpose of this work is to provide experimental data and to develop a model of the thermo-mechanical behaviour and to propose a design analysis method in the case of non-irradiated clads, in RIA-type situations. Mechanical tests were conducted on Cold-Worked-Stress-Relieved and on Recrystallized Zircaloy-4 sheets using various kinds of samples including smooth and notched tensile specimens and small punch tests. Temperature was set to 25, 250 and 600 C with hydrogen contents between 0 and 1000 ppm. The model is based on a simplified description of a Zircaloy polycrystal in which scalar isotropic ductile damage including void nucleation and growth is added. The model is also physically based to easily transfer parameters determined for one material state to another (e.g. transfer between sheet and tube or between different levels of irradiation). The model was implemented in the Finite Element software Zebulon using either an explicit or an implicit time integration scheme. Uniaxial tension tests were used to tune the model parameters for both materials, considering various values of temperature and hydrogen levels

    Whereas adults largely base their evaluations of others' actions on others' intentions, a host of research in developmental psychology suggests that younger children privilege outcome over intention, leading them to condemn accidental harm. To date, this question has been examined only with children capable of language production. In the current studies, we utilized a non-linguistic puppet show paradigm to examine the evaluation of intentional and accidental acts of helping or harming in 10-month-old infants. In Experiment 1 (n=64), infants preferred intentional over accidental helpers but accidental over intentional harmers, suggestive that by this age infants incorporate information about others' intentions into their social evaluations. In Experiment 2 (n=64), infants did not distinguish "negligently" accidental from intentional helpers or harmers, suggestive that infants may find negligent accidents somewhat intentional. In Experiment 3 (n=64), we found that infants preferred truly accidental over negligently accidental harmers, but did not reliably distinguish negligently accidental from truly accidental helpers, consistent with past work with adults and children suggestive that humans are particularly sensitive to negligently accidental harm. Together, these results imply that infants engage in intention-based social evaluation of those who help and harm accidentally, so long as those accidents do not stem from negligence.

    1989-01-01

    In this paper the relationship between accidental worldsheet symmetries of the string generating functional and target space invariance groups is discussed. Accidental symmetries are used to derive the invariance groups and effective low energy Lagrangian for the bosonic string, and the heterotic string compactified to four-dimensions on Z N orbifolds. The necessity of a new type of Green-Schwarz mechanism, associated with the auxiliary vector field in the four-dimensional N = 1 supergravity multiplet, is shown using these methods

    The number of RIA kits to be assessed has made feasible the introduction of a computerized technique for quick and reliable evaluation of quality checking of the kits. The proposed method makes use of a hyperbolic regression for the machine evaluation of the RIA measurements. The process can be used in its present form for the activity measurements of bound antigens in the system only. The calculator program does not use the data of the non-specific bounds (NBS value) and it contains procedures which can be solved by the given memory capacity of the calculator type proposed.

    2015-01-01

    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

    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.

    Patients frequent take acetaminophen to treat dental pain. One previous study found a high rate of overuse of nonprescription analgesics in an emergency dental clinic. The purpose of this study is to determine if patients with dental pain are more likely to be treated for accidental acetaminophen poisoning than patients with other types of pain. We conducted a case-control study at 2 urban hospitals. Cases were identified by chart review of patients who required treatment for accidental acetaminophen poisoning. Controls were self-reported acetaminophen users taking therapeutic doses identified during a survey of emergency department patients. For our primary analysis, the reason for taking acetaminophen was categorized as dental pain or not dental pain. Our primary outcome was the odds ratio of accidental overdose to therapeutic users after adjustment for age, sex, alcoholism, and use of combination products using logistic regression. We identified 73 cases of accidental acetaminophen poisoning and 201 therapeutic users. Fourteen accidental overdose patients and 4 therapeutic users reported using acetaminophen for dental pain. The adjusted odds ratio for accidental overdose due to dental pain compared with other reasons for use was 12.8 (95% confidence interval, 4.2-47.6). We found that patients with dental pain are at increased risk to accidentally overdose on acetaminophen compared with patients taking acetaminophen for other reasons. Emergency physicians should carefully question patients with dental pain about overuse of analgesics. Copyright © 2011 Elsevier Inc. All rights reserved.

    Accidental matter models are scenarios where the beyond-the-standard model physics preserves all the standard model accidental and approximate symmetries up to a cutoff scale related with lepton number violation. We study such scenarios assuming that the new physics plays an active role in neutrino mass generation, and show that this unavoidably leads to radiatively induced neutrino masses. We systematically classify all possible models and determine their viability by studying electroweak precision data, big bang nucleosynthesis and electroweak perturbativity, finding that the latter places the most stringent constraints on the mass spectra. These results allow the identification of minimal radiative accidental matter models for which perturbativity is lost at high scales. We calculate radiative charged-lepton flavor violating processes in these setups, and show that μ→eγ has a rate well within MEG sensitivity provided the lepton-number violating scale is at or below 5×10{sup 5} 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.

    Reports on accidental auto-injection of adrenaline are few. We encountered three cases of accidental injection of adrenaline. In this study, we have examined and reported the clinical courses and symptoms of our cases. CASE 1 involved a female physician in her 50s who had attended an explanatory meeting on auto-injection of adrenaline. She mistook EpiPen® to be the EpiPen trainer and accidentally injected herself with 0.3 mg EpiPen®. Her systolic/diastolic pressure peaked at 7 min to reach 144/78 mmHg and decreased to 120/77 mmHg at 14 min. Except for palpitation after 7 min, the only subjective symptom was local pain at the injection site. CASE 2 was noted in a 6-year-old boy. He accidentally pierced his right forefinger with 0.15 mg EpiPen®, and after 20 min, his right forefinger was swollen. The swelling improved 80 min after the accidental injection. CASE 3 was noted in a 4-year-old girl. She accidentally injected herself with 0.15 mg EpiPen®. Her systolic/diastolic pressure peaked at 23 min to reach 123/70 mmHg and decreased to 96/86 mmHg at 28 min. Severe adverse effects of accidental auto-injection of adrenaline were not observed in these three cases. Our findings suggest that while handling adrenaline auto-injectors, we should keep in mind the possibility of accidental injection.

    1997-12-31

    The requirements for protective clothing against accidental immersion are discussed and the advantages and limitations of the main types of immersion protection available are analysed. The variety of designs available reflects the various circumstances under which they may be used. In broad terms in the offshore industry these include the following activities: normal work without risk of immersion but with a possible need to abandon the rig or ship; work in areas where there is risk of accidentally falling into the sea; flying over the sea in a helicopter. The first response to sudden immersion in sea water, which must usually be considered to be cold, is a sudden gasp often followed by an immediate phase of uncontrolled breathing. Since control of ones breathing between and under the breaking waves is essential to staying alive, this is a critical time. After surviving this initial ``cold shock`` phase, the effects of body heat loss become hazardous. Protection against hypothermia has been the priority for those providing survival suits and protective clothing while the hazard of the immediate response to cold immersion has been unrecognised to a large extent.

    Lack of awareness and recognition of child maltreatment is the major reason behind underreporting. All victims often interact with the health care system for routine or emergency care. In several research works, non-accidental fractures are the second most common injury in maltreated children and it is represented up to one-third of cases. To determine the incidence of different types of accidental and non-accidental skeletal injuries among children, estimate the severity of injuries according to the modified injury severity score and to determine the degree of fractures either closed or opened (Gustiloe-Anderson open fracture classification). Moreover, identifying fractures resulting from child abuse and neglect. This aimed for early recognition of non-accidental nature of fractures in child maltreatment that can prevent further morbidity and mortality. A descriptive study was carried out on all children (109) with skeletal injuries who were admitted to both Main Alexandria and El-Hadara Orthopedic and Traumatology University Hospitals during six months. History, physical examination and investigations were done for the patients. A detailed questionnaire was taken to diagnose child abuse and neglect. Gustiloe-Anderson open fracture classification was used to estimate the degree of open fractures. Out of 109 children, twelve cases (11%) were categorized as child maltreatment. One case was physical abuse, eight cases (7.3%) were child neglect and three cases (2.8%) were labour exploitation. Road traffic accidents (RTA) was the commonest cause of skeletal injuries followed by falling from height. Regarding falls, they included 4 cases of stair falls in neglected children and another four cases of falling from height (balcony/window). The remaining 36 cases of falls were accidental. The skeletal injuries were in the form of fractures in 99 cases, dislocation in two cases, both fracture and/or dislocation in three cases, and bone deformity from brachial plexus injury

    2014-01-01

    To test young children’s false belief theory of mind in a morally relevant context, two experiments were conducted. In Experiment 1, children (N = 162) at 3.5, 5.5, and 7.5 years of age were administered 3 tasks: prototypic moral transgression task, false belief theory of mind task (ToM), and an “accidental transgressor” task, which measured a morally relevant false belief theory of mind (MoToM). Children who did not pass false belief ToM were more likely to attribute negative intentions to an accidental transgressor than children who passed false belief ToM, and to use moral reasons when blaming the accidental transgressor. In Experiment 2, children (N = 46) who did not pass false belief ToM viewed it as more acceptable to punish the accidental transgressor than did participants who passed false belief ToM. Findings are discussed in light of research on the emergence of moral judgment and theory of mind. PMID:21377148

    Compressed air is being used extensively as a source of energy at industries and in daily life. A variety of fatal injuries are caused by improper and ignorant use of compressed air equipments. Many types of injuries due to compressed air are reported in the literature such as colorectal injury, orbital injury, surgical emphysema, and so on. Most of these injuries are accidental in nature. It is documented that 40 pounds per square inch pressure causes fatal injuries to the ear, eyes, lungs, stomach, and intestine. Openings of body are vulnerable to injuries by compressed air. Death due to compressed air injuries is rarely reported. Many cases are treated successfully by conservative or surgical management. Extensive survey of literature revealed no reports of fatal injury to the upper respiratory tract and lungs caused by compressed air. Here, we are reporting a fatal event of accidental death after insertion of compressed air pipe into the mouth. The postmortem findings are corroborated with the history and discussed in detail.

  8. Evaluation of accidental coincidences for time-differential Moessbauer-spectroscopy

    1995-01-01

    The accidental coincidences of a measuring system based on time-to-amplitude conversion are considered in some detail for the case of low starting and high stopping rates. Two types of accidental coincidences are distinguished, those carrying time information and those without time information. Neglecting any deadtime effects of the detectors, analytical expressions for the calculation of the time distribution of the random coincidences are evaluated. The analytical expressions have been confirmed by Monte Carlo simulations. The procedure is applied to time-differential Moessbauer spectroscopy in order to extract the time spectra of true coincidences. The measured spectrum in a time channel turns out to be a superposition of the true spectrum (true coincidences), a time integral spectrum (random coincidences), and a weighted superposition of true spectra of other time channels (random but time carrying information). A measurement with a single line 57 Co/Rh-source and single line K[Fe(CN) 6 ].3H 2 O-absorber with stopping rates of 1 MBq shows agreement between the theoretical time-filtered spectra and the corrected measured spectra of true coincidences.

    This paper is dedicated to the experimental program, investigating CANDU type fuel behaviour in transient condition, as well as the facilities supporting this program. The tests Reactivity Initiated Accident type. The experiments were performed within TRIGA ACPR facility, installed at INSTITUTE for NUCLEAR POWER REACTORS, Pitesti, ROMANIA. Studies of the safety issues took a great international developement during last years. In USA, Japan, owners of the similar reactors, and USSR there are a big commitment to such programs, intended to establish the nuclear fuel behaviour under RIA-conditions. In our country, too, there are programs aiming a complete testing of the CANDU type fuels. As it is known, RIA is not a CANDU specific accident, but the fuel behaviour in such conditions can give useful informations on the fuel cladding failure threshold and about reflooding post LOCA heat transfer condition. Based on some papers and specific requirements it was initiated and developed a safety research program on CANDU type fuel using the ACPR. The paper describes the reactor,test capsule, instrumentation, fuel samples, tests, post irradiation results. (orig.)

    2012-01-01

    Retrospective dosimetry is one of the most important tools of accidental dosimetry for dose estimation when dose measurement was not planned. In the affected area many objects can be applied as natural dosimeters. The paper discusses our recent investigations on various electronic components and common salt (NaCl) having useful thermoluminescence (TL) properties. Among materials investigated the electronic components of cell phones seem promising for retrospective dosimetry purposes, having high TL responses, proper glow curve peaks and the intensity of TL peaks vs. gamma dose received provided nearly linear response in the dose range of 10 mGy–1.5 Gy. - Highlights: ► Electronic components and common salt were investigated for accidental and retrospective dosimetry. ► SMD resistors seem promising for retrospective dosimetry purposes. ► Table salt can be used effectively for accidental dosimetry purposes, as well.

  11. Accidental degeneracy in photonic bands and topological phase transitions in two-dimensional core-shell dielectric photonic crystals.

    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.

    As interim substance in the nuclear fuel enrichment process, Uranium Hexafluoride (UF 6 ) is widely applied in nuclear processing, enrichment and fuel fabrication plants. Because of its vivid chemical characteristics and special radiological hazard and chemical toxicity, great attention must be paid to accident of UF 6 leakage. The chemical reactions involved in UF 6 release processes were introduced, therewith potential release styles, pathways and characteristics of diffusion were analyzed. The results indicated that the accidental release process of UF 6 is not a simple passive diffusion. So, specific atmospheric diffusion model related to UF 6 releases need be used in order to analyze and evaluate accurately the accidental consequences. (authors)

    The advent of high-burnup fuel implementation in LWRs has generated international interest in high-burnup LWR fuel performance. Recent testing under simulated RIA conditions has demonstrated that certain fuel designs fail at peak fuel enthalpy values that are below existing regulatory criteria. Because many of these tests were performed with non-prototypically aggressive test conditions (i.e., with power pulse widths less than 10 msec FWHM and with non-protoypic coolant configurations), the results (although very informative) do not indisputably identify failure thresholds and fuel behavior. The capability of the TREAT facility to perform simulated RIA tests with prototypic test conditions is currently being evaluated by ANL personnel. TREAT was designed to accommodate test loops and vehicles installed for in-pile transient testing. During 40 years of TREAT operation and fuel testing and evaluation, experimenters have been able to demonstrate and determine the transient behavior of several types of fuel under a variety of test conditions. This experience led to an evolution of test methodology and techniques which can be employed to assess RIA behavior of LWR fuel. A pressurized water loop that will accommodate RIA testing of LWR and CANDU-type fuel has completed conceptual design. Preliminary calculations of transient characteristics and energy deposition into test rods during hypothetical TREAT RIA tests indicate that with the installation of a pressurized water loop, the facility is quite capable of performing prototypic RIA testing. Typical test scenarios indicate that a simulated RIA with a 72 msec FWHM pulse width and energy deposition of 1200 kJ/kg (290 cal/gm) is possible. Further control system enhancements would expand the capability to pulse widths as narrow as 40 msec. (author)

    EDF ordered to FRAMATOME by 1977 to complete post accidental long term studies on 'First Contrat-Programme' reactors, in order to demonstrate the safety criteria long term compliance, to get information on NSSS behaviour and to improve the post accidental procedures. Convenient analytical models were needed and EDF and FRAMATOME respectively developped the AXEL and FRARELAP codes. The main results of these studies is that for the smallest breaks, it is possible to manually undertake cooling and pressure reducing actions by dumping the steam generators secondary side in order to meet the RHR operating specifications and perform long term cooling through this system. A specific small breaks procedure was written on this basis. The EDF and FRAMATOME codes are continuously improved; the results of a French set of separate effects experiments will be incorporated as well as integral system verification

    Full Text Available En los tiempos antiguos no existía ley ni disposición alguna de carácter social que favoreciera a los trabajadores incapacitados por enfermedad o por accidente, por tanto, eran tratados como esclavos o considerados como animales. Los accidentes de trabajo y las enfermedades profesionales eran casi desconocidas antes de la introducción de la maquinaria en la industria, por lo cual no existía el derecho a indemnización por concepto de daños que sufriera el trabajador en el desempeño de sus labores. Solamente se conocen los edictos de Rotari (año 645 de la éra cristiana lanzados en Italia con el fin de reparar los accidentes de los obreros de la construcción y después, en la época del Renacimiento, algunas publicaciones que hablan de ciertas enfermedades de los trabajadores (Ellemborg 1473, Paracelso 1493-1541. Ya en la edad media la industria comenzó a tomar cierta importancia y dada la escasez de brazos, se vio obligado el patrón por fuerza de las circunstancias a prestar ayuda económica a los trabajadores incapacitados por una u otra causa. Los accidentes sucedidos en las industrias no se consideraban como de trabajo, por no conocerse el peligro que envolvía el empleo de la maqumana. En el siglo XVII y a principios del XVIII un médico italiano, Ramazzini habla del perjuicio que ocasionan ciertos trabajos en el organismo del individuo, produciendo alteraciones anatómicas y funcionales. Solamente a fines del siglo XVIII y a principios del XIX con la producción en masa, con el aumento del número de obreros y con la falta de protección, empezaron los accidentes de trabajo a hacerse notorios.

    AIM: To evaluate the type and nature of head injuries sustained by children under the age of 5 years who present to a busy accident and emergency (A and E) department following an accidental fall. MATERIALS AND METHODS: This study included all children under the age of 5 years, who over an 8-month period were referred to our A and E Department with head injury following an accidental fall. Data were collected regarding the height of the fall, whether or not stairs were involved, the type of surface that the child landed on and the height of the child. This was correlated with any soft-tissue injury or skull fracture. RESULTS: A total of 72 children (aged 4 months to 4.75 years) fulfilled all the criteria for an accidental fall. The heights of the falls ranged from less than 50 cm to over 3 m, with the majority below 1 m. Of the falls, 49 were onto a hard surface and 23 were onto a soft surface. Of the 72 children, 52 had visible evidence of head injury, 35 (71%) of 49 being the result of falls onto hard surfaces and 17 (74%) of 23 onto soft (carpeted) surfaces. There was no significant difference in the type of surface that resulted in a visible head injury. A visible head injury was seen in all children who fell from a height of over 1.5 m and in 95% of children who fell over 1 m. Of the 72 children, 32 (44%) had skull radiographs performed in accordance with established guidelines and 4 (12.5%) were identified as having a fracture. Of the 3 linear parietal fractures 2 were inflicted by falls of just over 1 m (from a work surface) and 1 by a fall of 80 to 90 cm onto the hard-edged surface of a stone fire surround. The 4th was a fracture of the base of skull following a fall from more than 3 m (from a first-storey window). CONCLUSIONS: In the vast majority of domestic accidents children do not suffer significant harm. Skull fractures are rare and probably occur in less than 5% of cases. To cause a skull fracture the fall needs to be from over 1 m or, if from a

    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)

    In 55 patients with various alcoholic liver diseases, serum type III procollagen aminopeptide (PIIIP) was measured on admission, on biopsy (2-4 weeks after admission) and on discharge from hospital (3 months after admission) using RIA-gnost PIIIP coated tube, an assay kit recently launched by Hoechst Japan Limited. Serum PIIIP on admission showed a good correlation with the degree of hepatic fibrosis and was significantly higher in any disease group than in healthy controls, suggesting its usefulness as an indicator of hepatic fibrosis. After abstinence, however, serum PIIIP level exhibited an increasing tendency in all the disease groups expect alcoholic hepatitis, and the number of laboratory tests showing a significant correlation with PIIIP decreased as compared with that on admission. The mechanism of serum PIIIP elevations seen after abstience is yet to be elucidated in detail, considering their possible association with factors other than collagen synthesis in the liver.

This single-center study retrospectively investigates 372 patients who underwent MIS TLIF and were mobilized within 24 hours after surgery. The frequency of accidental durotomies, intraoperative closure technique, body mass index, and history of previous surgery was recorded. Results. We identified 32 accidental durotomies in 514 MIS TLIF levels (6.2%. Analysis showed a statistically significant relation of accidental durotomies to overweight patients (body mass index ≥25 kg/m2; P=0.0493. Patient age older than 65 years tended to be a positive predictor for accidental durotomies (P=0.0657. Mobilizing patients on the first postoperative day, we observed no durotomy-associated complications. Conclusions. The frequency of accidental durotomies in MIS TLIF is low, with overweight being a risk factor for accidental durotomies. The minimally invasive approach seems to minimize durotomy-associated complications (CSF leakage, pseudomeningocele because of the limited dead space in the soft tissue. Patients with accidental durotomy can usually be mobilized within 24 hours after MIS TLIF without increased risk. The minimally invasive TLIF technique might thus be beneficial in the prevention of postoperative immobilization-associated complications such as venous thromboembolism.

Segundo Ochsner & Mills (1, ela ocorreu com a artéria coronária direita em 0,9% e com o ramo interventricular em 0,2%. A localização da lesão e as condições patológicas relacionadas ao comprimento e diâmetro da coronária podem auxiliar na exposição da coronária intracavitária para uma revascularização apropriada. Freqüentemente os cirurgiões não estão habituados com a posição intracavitária e, durante a dissecção, podem abrir uma câmara cardíaca onde o vaso penetra. Os problemas que podem advir dai são a entrada de ar para a cavidade, a dificuldade na exposição do vaso, o sangramento e a obstrução da artéria durante o fechamento da miotomia. São relatados os casos de 3 pacientes que necessitaram de revascularização cirúrgica do miocárdio e que apresentavam a artéria coronária direita intracavitária.

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.

    We present the main findings of the 5th National Audit Project on accidental awareness during general anaesthesia. Incidences were estimated using reports of accidental awareness as the numerator, and a parallel national anaesthetic activity survey to provide denominator data. The incidence of certain/probable and possible accidental awareness cases was ~1:19 600 anaesthetics (95% CI 1:16 700-23 450). However, there was considerable variation across subtypes of techniques or subspecialties. The incidence with neuromuscular blockade was ~1:8200 (1:7030-9700), and without it was ~1:135 900 (1:78 600-299 000). The cases of accidental awareness during general anaesthesia reported to 5th National Audit Project were overwhelmingly cases of unintended awareness during neuromuscular blockade. The incidence of accidental awareness during caesarean section was ~1:670 (1:380-1300). Two thirds (82, 66%) of cases of accidental awareness experiences arose in the dynamic phases of anaesthesia, namely induction of and emergence from anaesthesia. During induction of anaesthesia, contributory factors included: use of thiopental; rapid sequence induction; obesity; difficult airway management; neuromuscular blockade; and interruptions of anaesthetic delivery during movement from anaesthetic room to theatre. During emergence from anaesthesia, residual paralysis was perceived by patients as accidental awareness, and commonly related to a failure to ensure full return of motor capacity. One third (43, 33%) of accidental awareness events arose during the maintenance phase of anaesthesia, most due to problems at induction or towards the end of anaesthesia. Factors increasing the risk of accidental awareness included: female sex; age (younger adults, but not children); obesity; anaesthetist seniority (junior trainees); previous awareness; out-of-hours operating; emergencies; type of surgery (obstetric, cardiac, thoracic); and use of neuromuscular blockade. The following factors were

    Accidental falls are a major public health concern among people of all ages. Little is known about whether an individual-level housing-based socioeconomic status measure is associated with the risk of accidental falls. Among 12,286 Mayo Clinic Biobank participants residing in Olmsted County, Minnesota, subjects who experienced accidental falls between the biobank enrollment and September 2014 were identified using ICD-9 codes evaluated at emergency departments. HOUSES (HOUsing-based Index of SocioEconomic Status), a socioeconomic status measure based on individual housing features, was also calculated. Cox regression models were utilized to assess the association of the HOUSES (in quartiles) with accidental fall risk. Seven hundred eleven (5.8%) participants had at least one emergency room visit due to an accidental fall during the study period. Subjects with higher HOUSES were less likely to experience falls in a dose-response manner (hazard ratio: 0.58; 95% confidence interval: 0.44-0.76 for comparing the highest to the lowest quartile). In addition, the HOUSES was positively associated with better health behaviors, social support, and functional status. The HOUSES is inversely associated with accidental fall risk requiring emergency care in a dose-response manner. The HOUSES may capture falls-related risk factors through housing features and socioeconomic status-related psychosocial factors. Copyright © 2017 Elsevier Inc. All rights reserved.

    Objectives The aims of this study were to (i) investigate the association between night work or long work weeks and the risk of accidental injuries and (ii) test if the association is affected by age, sex or socioeconomic status. Methods The study population was drawn from the Danish version of the European Labour Force Survey from 1999-2013. The current study was based on 150 438 participants (53% men and 47% women). Data on accidental injuries were obtained at individual level from national health registers. We included all 20-59-year-old employees working ≥32 hours a week at the time of the interview. We used Poisson regression to estimate the relative rates (RR) of accidental injuries as a function of night work or long work weeks (>40 hours per week) adjusted for year of interview, sex, age, socioeconomic status (SES), industry, and weekly working hours or night work. Age, sex and SES were included as two-way interactions. Results We observed 23 495 cases of accidental injuries based on 273 700 person years at risk. Exposure to night work was statistically significantly associated with accidental injuries (RR 1.11, 99% CI 1.06-1.17) compared to participants with no recent night work. No associations were found between long work weeks (>40 hours) and accidental injuries. Conclusion We found a modest increased risk of accidental injuries when reporting night work. No associations between long work weeks and risk of accidental injuries were observed. Age, sex and SES showed no trends when included as two-way interactions.

La literatura señala que los accidentes de tránsito están asociados confactores de comportamiento, seguridad de los vehículos y la precariedad del espacio urbano.Reducir el número de accidentes de tránsito es un reto para los gestores deárea. La educación en el tránsito debe considerar la vigilancia como una estrategia eficaz para cambiar el comportamiento del conductor,principalmente en relación con el exceso de velocidad y el consumo de alcohol asociado con la conducción.La ingeniería tiene un papel importante para promover un entorno seguro,en el que la convivencia de peatones, ciclistas y conductores sea posible. El escenario en que se configura los accidentes de tránsito muestra la necesidad de los profesionales de la salud reconsiderar sus prácticas con el fin de replantear la imagen de la víctima de accidentes, las formas de trabajo de prevención de accidentes, la educación en el tránsito de peatones y conductores, con el fin de promover la salud y la cultura de paz. Existe la necesidad de políticas de salud públicay estrategias que hacen posible acceso a las acciones tanto en el campo preventivo como en el campo de la rehabilitación.

    Loss-of-function mutations in the gene SCN5A can cause Brugada syndrome (BrS), which is an inherited form of idiopathic ventricular fibrillation. We report the case of a 46-year-old patient, with no previous medical history, who had ventricular fibrillation after accidental inhalation of gasoline vapors. His electrocardiogram (ECG) showed a typical type-1 BrS pattern that persisted after the acute event. Genetic investigations allowed the identification of a novel SCN5A mutation leading to a frame-shift and early termination of the channel protein. Biochemical and cellular electrophysiology experiments confirmed the loss-of-function of the mutant allele. The patient was implanted with a cardioverter/defibrillator.

    Full Text Available BACKGROUND: Esophagectomy presents the highest rate of postoperative pulmonary complications among all types of upper abdominal surgery. The benefits of chest physical therapy in patients undergoing upper abdominal surgery have been shown by many studies; however, its specific effect in patients receiving esophagectomy has been seldom investigated. OBJECTIVES: This study aimed to compare the frequency of respiratory complications in patients undergoing esophagectomy receiving chest physical therapy compared to no treatment. METHODS: 70 consecutive patients were evaluated retrospectively and allocated to two groups: control group (CG=no physical therapy; n=30 and chest physical therapy group (PTG; n=40. Patients received chest physical therapy which includes lung re-expansion and airway clearance maneuvers. They were not submitted to either noninvasive ventilation or exercises with devices that generate airways positive pressure. All patients were instructed to early mobilization. Information about pre-operative and respiratory complications were collected. Statistic analysis to compare the frequency of respiratory complications was performed by the Z test. The significance level was set to 5%. RESULTS: Patients in the CG and PTG were similar in terms of age, BMI, smoking and drinking status, malignant diseases, surgical and anesthesia duration and types of esophagectomy (p>0.05. Our results show that patients received chest physical therapy after esophagectomy had a lower frequency of respiratory complications (15% vs. 37%, pCONTEXTUALIZAÇÃO: A esofagectomia apresenta a maior taxa de complicações pulmonares pós-operatórias dentre as cirurgias abdominais altas.

    Full Text Available The financial loss due to working accidents is very substantial, quite apart from the actual loss of human lives. Hence avoiding these accidents is a most important matter. The accident index in the various industries shows a rate of increase that is larger than should be the case in proportion to the development of the industries concerned, and the larger number of employees. The fact that these indexes are smaller in many countries, however, shows that these accidents can be considerably reduced if suitable measures are taken to avoid them. In chapter 2 of our magazine, issue no. 178, a variety of reasons were discussed that may originate accidents, although these causes are not directly linked to the accident itself. In this article mention is made of some of the measures that can be taken in the handling of cutting and welding equipment, and also of inflammable liquids, to prevent possible accidents.El peso de los accidentes de trabajo sobre la economía supone cantidades muy grandes que, independientemente del inestimable valor de una vida humana, realzan la importancia de la prevención de accidentes. Los índices de accidentes muestran en diferentes industrias un crecimiento mayor de lo que debería corresponder proporcionalmente, habida cuenta del crecimiento laboral. El hecho de que en distintos países los índices sean inferiores, demuestra que se pueden conseguir buenos frutos si se concede primordial importancia a que los trabajos se realicen con las debidas medidas de seguridad. En el Capítulo 2, número 178 de esta Revista, se detallaron diversas causas que pueden originar un accidente sin estar ligadas en forma directa con una tarea determinada. En el presente trabajo se indican algunas de las medidas que deben observarse en el manejo de los equipos de soldadura y corte, así como en el transvase de líquidos inflamables.

    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

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

    In order to benchmark the newly developed beam dynamics code TRACK we have performed comparisons with well established existing codes. During code development, codes like TRANSPORT, COSY, GIOS and RAYTRACE were used to check TRACK's implementation of the different beam line elements. To benchmark the end-to-end simulation of the RIA driver linac, the simulation of the low-energy part (from the ion source to the entrance of the SC linac) was compared with PARMTEQ and found to agree well. For the simulation of the SC linac the code IMPACT is used. Prior to these simulations, the code IMPACT had to be updated to meet the special requirements of the RIA driver linac. Features such as multiple charge state acceleration, stripper simulation and beam collimation were added to the code. IMPACT was also modified to support new types of rf cavities and to include fringe fields for all the elements. This paper will present a comparison of the beam dynamics simulation in the RIA driver linac between the codes TRACK and I...

    Full Text Available Integrated Deterministic and Probabilistic Safety Analysis (IDPSA of dynamic systems calls for the development of efficient methods for accidental scenarios generation. The necessary consideration of failure events timing and sequencing along the scenarios requires the number of scenarios to be generated to increase with respect to conventional PSA. Consequently, their postprocessing for retrieving safety relevant information regarding the system behavior is challenged because of the large amount of generated scenarios that makes the computational cost for scenario postprocessing enormous and the retrieved information difficult to interpret. In the context of IDPSA, the interpretation consists in the classification of the generated scenarios as safe, failed, Near Misses (NMs, and Prime Implicants (PIs. To address this issue, in this paper we propose the use of an ensemble of Semi-Supervised Self-Organizing Maps (SSSOMs whose outcomes are combined by a locally weighted aggregation according to two strategies: a locally weighted aggregation and a decision tree based aggregation. In the former, we resort to the Local Fusion (LF principle for accounting the classification reliability of the different SSSOM classifiers, whereas in the latter we build a classification scheme to select the appropriate classifier (or ensemble of classifiers, for the type of scenario to be classified. The two strategies are applied for the postprocessing of the accidental scenarios of a dynamic U-Tube Steam Generator (UTSG.

    The application of lamp phosphors for accidental dosimetry is a new concept. Since the materials used in fluorescent lamps are good photo luminescent materials, if one can either use the inherent defects present in the phosphor or add suitable modifiers to induce thermoluminescence (TL) in these phosphors, then the device (fluorescent lamp) can be used as an accidental dosemeter. In continuation of our search for a suitable phosphor material, which can serve both as an efficient lamp phosphor and as a good radiation monitoring device, detailed examination has been carried out on cerium and terbium-doped lanthanum phosphate material. A 90 Sr beta source with 50 mCi strength (1.85 GBq) was used as the irradiation source for TL studies. The TL response as a function of dose received was examined for all phosphors used and it was observed that the intensity of the TL peak vs. dose received was a linear function in the dose range 0.1-200 Gy in each case. Incidentally LaPO 4 :Ce,Tb is a component of the compact fluorescent lamp marketed recently as an energy bright light source. Besides having very good luminescence efficiency, good dosimetric properties of these phosphors render them useful for their use in accidental dosimetry also. (authors)

    Full Text Available Paciente de 39 anos, portador de hipertensão arterial não controlada, submetido a cirurgia para tratamento de dissecção aguda de aorta tipo I. Devido ao grande envolvimento do óstio coronário direito pela dissecção aórtica, optou-se pela ressecção da porção comprometida do vaso, com interposição de tubo não valvulado de Dacron na aorta ascendente, suspensão da valva aórtica e ligadura do óstio da artéria coronária direita. Como não havia presença de aterosclerose no ramo interventricular anterior e na artéria coronária direita, decidimos realizar um enxerto venoso entre as artérias. O enxerto intercoronário apresentou bom funcionamento e todo o território dependente da coronária direita manteve boa contratilidade. O paciente recebeu alta hospitalar em boas condições clínicas, com função rniocárdica preservada.A thirty nine-year-old patient presenting arterial hypertension was operated upon for type I acute aortic dissection. Due to important alterations in the ascendent aorta with involvement of the right coronary ostium, the surgical procedure included resection of the segment of aorta containing the intimal tear and replacement with a Dacron prosthesis, suspension of the aortic valve and ligadure of the right coronary ostium. Technical difficulties brought the necessity of a different approach for the myocardium revascularization. Instead of the traditional described procedures, an intercoronary venous graft was put between the anterior interventricular artery (branch of the left coronary artery and the right coronary artery. The intercoronary graft presented a good flow since the begining, keeping a good myocardial contratility. Patient left the hospital in a good clinical condition, with preserved myocardial function. Intercoronary graft should be an efficient alternative for revascularization of a corohary artery involved by aortic dissections.

    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 Working accidents have a high moral and material impact, and are often easy to avoid, at least in about half the cases. Hence it is most important that campaigns for the reduction of these accidents should be correctly planned, so that such campaigns should not merely result in additional expense, and in a lowering of staff morale, when workers find themselves operating in an unpleasant and dangerous activity. In addition to special requirements, which may be studied in a later paper, and which must necessarily cover a very wide number of alternative cases, there are circumstances of a general nature, such as financial and moral consequences, and psychological repercussions, which influence the prevention of accidents and are the subject of this article.La notable repercusión moral y material que tienen los accidentes de trabajo y la fácil evitación de los mismos, por lo menos en la mitad de los casos, hacen sumamente importante que las campañas de prevención de accidentes estén bien orientadas y proyectadas, para evitar que se traduzcan, únicamente, en un gasto más y en una disminución de la moral del personal, al ver, éste, que está situado en medio de un ambiente desagradable y peligroso. Además de las normas particulares, que pueden ser objeto de otro trabajo posterior, y que han de ser forzosamente amplias, debido a la multiplicidad de factores que intervienen, hay, sin embargo, unas consideraciones de carácter general, tales como repercusiones económicas y morales y factores psicológicos que influyen en la prevención de accidentes y que son objeto del presente artículo.

    In 1993 December in IGR reactor of Inst. of Atomic Energy of National Nuclear Center of Republic of Kazakstan the second batch of in-pile testing of perspective cermet fuel elements under the condition, simulating RIA type accident was conducted. In the second batch of testing during eight start-ups 10 cermet fuel elements were examined. Among which 8 of monolith type and 2 fuel elements with false jacket beside cladding (FJF), as well as, 6 standard fuel elements of WWER-1000 type reactor with dioxide fuel were tested. 2 fuel elements - cermet and standard were placed into capsule filled with water. To measure energy release for the each start-up two fission monitor and inside core control gauge were placed. In all the start-ups operation mode of IGR was neutron pulse. Power of fuel element kept changing from 151 to 336 k W; energy release was 38-93 kJ/gr m 235 U; maximum temperature of cermet fuel was 1943-2173 K, of dioxide fuel - 1923-2843 K. The testing has demonstrated that operability of cermet fuel elements under reactivity accident condition with pulse width of 0,2 s is, at least, not less that operability of dioxide fuel elements, through advantages of cermet fuel under these conditions are revealed to the least extent

    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)

    A modular, data-based system approach has been developed to facilitate computational simulation of multi-dimensional pollutant dispersion in atmospheric, steam, estuary, and groundwater applications. This system is used to assess effects of accidental releases of pollutants to the environment. Model sophistication ranges from simple statistical to complex three-dimensional numerical methods. The system used specifies desired degree of model sophistication from a terminal. The model used depends on the particular type of problem being solved, and on a basis of merit related to computer cost. The results of prediction for several model problems are presented.

    Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for "Weightlifting." Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as "accidental" if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4,111 patients. Accidental injuries decreased (p 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p injuries (n = 2,565) showed that the oldest categories (19-22 and 23-30 yr) demonstrated a greater percentage of sprains and strains relative to younger age categories (p injuries sustained in the 8 to 13 group were to the hand and foot and were most often related to "dropping" and "pinching" in the injury descriptions, and there was an increased percentage of fractures in the 8 to 13 group relative to all other groups (p injuries are the result of accidents that are potentially preventable with increased supervision and stricter safety guidelines.

    Quantitative approaches are part of the understanding of contour integration and the Gestalt law of good continuation. The present study introduces a new quantitative approach based on the a contrario theory, which formalizes the non-accidentalness principle for good continuation. This model yields an ideal observer algorithm, able to detect non-accidental alignments in Gabor patterns. More precisely, this parameterless algorithm associates with each candidate percept a measure, the Number of False Alarms (NFA), quantifying its degree of masking. To evaluate the approach, we compared this ideal observer with the human attentive performance on three experiments of straight contours detection in arrays of Gabor patches. The experiments showed a strong correlation between the detectability of the target stimuli and their degree of non-accidentalness, as measured by our model. What is more, the algorithm's detection curves were very similar to the ones of human subjects. This fact seems to validate our proposed measurement method as a convenient way to predict the visibility of alignments. This framework could be generalized to other Gestalts.

    What is the future of RIA? Has the application of RIA peaked? Will other and competing tests such as immunofluorescence and ELISA systems displace or replace the method? RIA is a sensitive, precise, and very often specific analytical tool. Its primary advantage is exquisite sensitivity. Problems related to specificity of antibody and/or antigen identification are reviewed in this paper. The same limitations will be encountered in the similar techniques of enzyme immunologic determination. Increasing difficulties with waste disposal of either radioactive material and/or organic solvents will cause those who utilize radionuclides to look again at alternatives. RIA has been an exciting developmental tool that has led the authors to look at dynamic physiologic and biochemical interactions. The time may come when there is replacement of the radionuclide portion by enzymes or fluorescent material

    Full Text Available Após a cirurgia de laringectomia total, o fluxo aéreo nasal é transferido definitivamente para o traqueostoma, comprometendo a chegada de moléculas odoríferas até a cavidade nasal, podendo repercutir em alterações na percepção olfatória e gustatória nesses indivíduos. OBJETIVO: Avaliar as funções do olfato e do paladar em laringectomizados totais. Desenho do estudo: Estudo de série. MÉTODO: A amostra envolveu um grupo com 25 pacientes submetidos à laringectomia total e outro grupo de comparação com 25 pacientes não laringectomizados. A função gustatória foi avaliada por tiras gustativas de papel de filtro. Para avaliação da função olfatória, foi aplicado o teste Brief Smell Identification Test. RESULTADOS: No grupo de laringectomizados, houve maior frequência de hipogeusia (80%; p < 0,05, assim como de hiposmia (88%; p < 0,001, isoladas e concomitantes (72%; p < 0,001. Na discriminação dos sabores, o sabor amargo não diferiu entre os grupos, diferentemente dos demais sabores. No aspecto olfatório, os laringectomizados tiveram pior desempenho na detecção de odores de alerta e os relacionados à alimentação. Identificou-se que história de tabagismo e de alcoolismo foi significantemente mais frequente dentre laringectomizados. CONCLUSÃO: A diminuição das funções olfatória e gustatória em laringectomizados totais foi evidenciada nesse estudo.

    2018-01-01

    The paper is devoted to the assessment of accidental risks occurring at the works engaged in stone extracting and petroleum production. Two basic kinds of accidents common for stone extracting and petroleum production have been chosen to be discussed in the part under consideration. The most dangerous accidental situation characteristic for a stone milling line is an unsanctioned explosion, UE, of blasting agents used for the development of stone deposits. The analysis of a risk occurrence in certain accidental situations is to be carried out. With reference to petroleum extraction, a combustibles and lubricants (C & L) explosion is the most dangerous of characteristic accidental situations. To reveal the most probable causes of accidental situations to be realized, a graph of cause and effect relations has been constructed for each of the accidental situations most probable causes to real situation of an accident. Disasters of a natural origin are the most probable causes of unsanctioned explosions at the deposits of stone raw materials. Technology related natural disasters are the most probable causes of unsanctioned explosions to be realized at multiple well platforms engaged in petroleum production.

    This is a case report concerning a veterinarian who spilled detomidine and butorphanol on dermatitic hands while sedating a horse. This resulted in acute poisoning from which the patient spontaneously recovered with supportive management. Veterinarians often suffer from occupational dermatitis and handle strong sedatives with no gloves while working around unpredictable animals. Thus, this group is at risk of accidental self-poisoning from this method.

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

    Tunturivuori, Lasse

    2014-01-01

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

  17. Dose assessment under incidental and accidental conditions

    International Nuclear Information System (INIS)

    Huebschmann, W.G.

    1988-01-01

    Dose assessment for the licesing process of a nuclear power plant covers the routine release of radioactive substances into the atmosphere as well as releases due to incidents. Source terms for these incidents are evaluated by the detailed incident analysis of the plant. The types of incidents to be covered are determined in the FRG by the ''Stoerfall-Leitlinien'' of the Ministry of the Interior. The calculation of dose equivalents in the environment of the plant differs from the calculation of doses due to routine releases, as incidents are single events occuring at undeterminate time, and the results must be conservative. Some details are being described. During the operation of the plant it is essential to measure not only the radioactivity release rates but also the necessary meteorological parameters for the instantaneous determination of the atmospheric dispersion in case of incidental or accidental releases of radioactivity. This instantaneous assessment assists in taking measurements of ground contamination and in deciding about countermeasures for the protection of plant personnell and population. (author) [pt

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

    1977-01-01

    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) [fr

    Accidents are a preventable cause of death. Unfortunately it accounts for a large number of deaths in many societies. In Kuwait, road traffic accidents (RTA) is the leading cause of death in young people. The study investigated the patterns of accidental deaths in Kuwait, one of the Gulf States which incorporates a wide variety of multi-ethnic communities. The study was retrospective from 2003-2009. Data of forensic cases were collected from the general department of criminal evidence (GDCE) in the ministry of interior (MOI).We attempted to find out causes of accidental death and the prevelance of each cause. Furthermore, the relationship of demographic factors (eg. Age, sex, marital status and nationality) with each cause of accidental death in Kuwait were studied. The material of this study constituted a total of 4886 reported accidental deaths referred for Medico-legal examination. Road traffic accidents was by far the most prevalent cause of death (64.6%) followed by fall from height (13.1%). Poisoning and mine explosions were amongst the least common causes. The government of Kuwait needs to take strong measures to promote safety in the workplace and households by educational campaigns.

    Non-Accidental Trauma (NAT) is a significant cause of childhood morbidity and mortality, causing 50% of trauma-related deaths at our institution. Our purpose was to evaluate the necessity of primary surgical evaluation and admission to the trauma service for children presenting with NAT. We reviewed all NAT patients from 2007-2011. Injury types, demographic data, and hospitalization information were collected. Comparisons to accidental trauma (AT) patients were made using Wilcoxon rank sum and Student's t tests. We identified 267 NAT patients presenting with 473 acute injuries. Injuries in NAT patients were more severe than in AT patients, and Injury Severity Scores, ICU admission rates, and mortality were all significantly (pinjury were seen in patients with closed head injuries (72%), extremity fractures (51%), rib fractures (82%), and abdominal/thoracic trauma (80%). Despite these complex injury patterns, only 56% received surgical consults, resulting in potential delays in diagnosis, as 24% of abdominal CT scans were obtained >12 hours after hospitalization. Given the high incidence of polytrauma in NAT patients, prompt surgical evaluation is necessary to determine the scope of injury. Admission to the trauma service and a thorough tertiary survey should be considered for all patients. Copyright © 2013 Elsevier Inc. All rights reserved.

    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.

    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.

    To investigate the impact of narrative verdicts on suicide statistics among 10-19-year-olds; to identify the number and rate of suicide and accidental deaths, particularly in 10-14-year-olds. National cohort study. England and Wales. Mid-year population estimates from the Office for National Statistics (ONS) were used to calculate rates per 100,000 population for suicide (undetermined and suicide verdicts) and accidental deaths (poisoning, hanging) for those aged 10-14 and 15-19. Trends in rates over time (2001-2010) were investigated using Poisson regression. Interaction tests were carried out to determine differences in trends between the two time periods (2001-2005 and 2006-2010). There were 1523 suicides (2.25/100,000). Suicide rates were highest in those aged 15-19 years (4.04/100,000) and in males (3.14/100,000). Between 2001 and 2010, rates significantly decreased among those aged 15-19 years (incidence rate-ratio (IRR): 0.95; 95% CI 0.93 to 0.97), with no change in rates of accidental deaths (IRR: 1.01, 95% CI 0.95 to 1.07). However, there was a significant interaction between the two time periods for accidental poisonings (2001-2005: IRR: 0.79 (95% CI 0.69 to 0.91); 2006-2010: IRR: 1.01 (95% CI 0.89 to 1.15), interaction p=0.012) and accidental hangings (2001-2005: IRR: 0.93 (95% CI 0.76 to 1.14); 2006-2010: IRR: 1.25 (95% CI 1.04 to 1.49), interaction=0.01) Undetermined deaths significantly decreased among females aged 15-19 yeras (IRR: 0.93; 95% CI 0.88 to 0.98). There were no significant trends among 10-14-year-olds. Rates of suicide are higher among older adolescents and males. There was a significant fall in suicide rates in males aged 15-19 years that was not accounted for by changes in rates of accidental death. The absence of a significant trend in suicide or accidental deaths in those aged 10-14 years may have been the result of small numbers. However, monitoring should continue to identify longitudinal trends in all young people.

    We describe a case of a 43-yr-old female with severe multiorgan injury after accidental poisoning with Colchicum autumnale, which was mistaken for wild garlic (Allium ursinum). Both plants grow on damp meadows and can be confused in the spring when both plants have leaves but no blossoms. The autumn crocus contains colchicine, which inhibits cellular division. Treatment consisted of supportive care, antibiotic therapy, and granulocyte-directed growth factor. The patient was discharged from the hospital after three weeks. Three years after recovery from the acute poisoning, the patient continued to complain of muscle weakness and intermittent episodes of hair loss.

    This report documents conditions, data and results of dose calculations for accidental and normal operation releases of tritium and activation products, performed within the NET subtask SEP2.2 ('NET-Benchmark') of the European Fusion Technology Programme. For accidental releases, the computer codes UFOTRI and COSYMA for assessing the radiological consequences, have been applied for both deterministic and probabilistic calculations. The influence on dose estimates of different release times (2 minutes / 1 hour), two release heights (10 m / 150 m), two chemical forms of tritium (HT/HTO), and two different model approaches for the deposition velocity of HTO on soil was investigated. The dose calculations for normal operation effluents were performed using the tritium model of the German regulatory guidelines, parts of the advanced dose assessment model NORMTRI still under development, and the statistical atmospheric dispersion model ISOLA. Accidental and normal operation source terms were defined as follows: 10g (3.7 10 15 Bq) for accidental tritium releases, 10 Ci/day (3.7 10 11 Bq/day) for tritium releases during normal operation and unit releases of 10 9 Bq for accidental releases of activation products and fission products.

    Full text: A portable TLD measuring system was constructed at the J. Stefan Institute many years ago, motivated by the thread of a catastrophic nuclear event. It was designed for fast measurements in accidental dosimetry mainly for military and civil protection use. The system consists of a robust portable measuring unit built for measurements in field conditions, sized about 40 cm in diameter and weighting 5 kg. Dosimeters are based on CaF 2 :Mn ceramic tablets closed in water resistant plastic housings. In original design producer assured measuring range from cGy to kGy. Specially designed energy compensating filters are used to satisfy requirements for energy response from 0,1 to 3 MeV. Stability of readings is maintained with the temperature stabilized light source. Measuring time for manually driven heating-reading cycle of one dosimeter is about 30 sec. Many systems of the type with sets of dosimeters were stored unused for some years in depositories of different institutions. Modernization of equipment in last years raised questions of applicability of such measurement systems for contemporary needs. The system was thus tested in a secondary standards dosimetry laboratory for compliance with up to date requirements for accidental individual monitoring. Dosimeter characteristics as repeatability, linearity and directional response were of particular interest. As a result of the tests, technical improvements are suggested to extent systems measuring capabilities in order to meet new standards. Possibilities of its use in different fields of dosimetry are discussed, where quick in field measurements of high doses is required as for example in medicine or in civil protection motivated by the new threads of terrorist attacks.

    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.

J Strength Cond Res 23(7): 2054–2060, 2009—Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for “Weightlifting.” Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as “accidental” if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4, 111 patients. Accidental injuries decreased (p 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p injuries (n = 2, 565) showed that the oldest categories (19–22 and 23–30 yr) demonstrated a greater percentage of sprains and strains relative to younger age categories (p injuries sustained in the 8 to 13 group were to the hand and foot and were most often related to “dropping” and “pinching” in the injury descriptions, and there was an increased percentage of fractures in the 8 to 13 group relative to all other groups (p injuries are the result of accidents that are potentially

    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 ...

    1991-01-01

    To develop a homologous radioimmunoassay (RIA) for a hormone of a small or rare animal often meets difficulty in collecting a large amount of purified antigen required for antibody production. On the other hand, to employ a heterologous RIA to estimate the hormone often gives poor sensitivity. To overcome this difficulty, a 'hetero-antibody' RIA was studied. In a hetero-antibody RIA system, a purified preparation of a hormone is used for radioiodination and standardization and a heterologous antibody to the hormone is used for the first antibody. Canine motilin and rat LH were selected as examples, and anti-porcine motilin and anti-hCG, anti-hCGβ or anti-ovine LHβ was used as the heterologous antibody. The sensitivities of the hetero-antibody RIAs were much higher than those of heterologous RIAs in any case, showing that these hetero-antibody RIA systems were suitable for practical use. To clarify the principle of hetero-antibody RIA, antiserum to porcine motilin was fractionated on an affinity column where canine motilin was immobilized. The fraction bound had greater constants of affinity with both porcine and canine motilins than the rest of the antibody fractions. This fraction also reacted with a synthetic peptide corresponding to the C-terminal sequence common to porcine and canine motilins in a competitive binding test with labeled canine motilin. These results suggest that an antibody population having high affinity and cross-reactivity is present in polyclonal antiserum and indicate that the population can be used in hetero-antibody RIA at an appropriate concentration.

    The 10 MW high-temperature gas-cooled test module (HTR-10) is a graphite-moderated and helium-cooled pebble bed reactor prototype that was designed to demonstrate the technical and safety feasibility of this type of reactor project under normal and accidental conditions. In addition, one of the systems responsible for ensuring the safe operation of this type of reactor is the passive decay heat removal system (DHRS), which operates using passive heat removal processes. A demonstration of the heat removal capacity of the DHRS under accidental conditions was analyzed based on a benchmark problem for design-based accidents on an HTR-10, i.e., the pressurized loss of forced cooling (PLOFC) described in technical reports produced by the International Atomic Energy Agency. In fact, the HTR-10 is also a proof-of-concept reactor for the high-temperature gas-cooled reactor pebble-bed module (HTR-PM), which generates approximately 25 times more heat than the HTR-10, with a thermal power of 250 MW, thereby requiring a DHRS with a higher system capacity. Thus, because an HTR-10 is a prototype reactor for an HTR-PM, a scaling analysis of the heat transfer process from the reactor to the DHRS was carried out between the HTR-10 and HTR-PM systems to verify the distortions of scale and the differences between the main dimensionless numbers from the two projects.

    The 10 MW high-temperature gas-cooled test module (HTR-10) is a graphite-moderated and helium-cooled pebble bed reactor prototype that was designed to demonstrate the technical and safety feasibility of this type of reactor project under normal and accidental conditions. In addition, one of the systems responsible for ensuring the safe operation of this type of reactor is the passive decay heat removal system (DHRS), which operates using passive heat removal processes. A demonstration of the heat removal capacity of the DHRS under accidental conditions was analyzed based on a benchmark problem for design-based accidents on an HTR-10, i.e., the pressurized loss of forced cooling (PLOFC) described in technical reports produced by the International Atomic Energy Agency. In fact, the HTR-10 is also a proof-of-concept reactor for the high-temperature gas-cooled reactor pebble-bed module (HTR-PM), which generates approximately 25 times more heat than the HTR-10, with a thermal power of 250 MW, thereby requiring a DHRS with a higher system capacity. Thus, because an HTR-10 is a prototype reactor for an HTR-PM, a scaling analysis of the heat transfer process from the reactor to the DHRS was carried out between the HTR-10 and HTR-PM systems to verify the distortions of scale and the differences between the main dimensionless numbers from the two projects.

  20. Accidental Beam Losses and Protection in the LHC

    Schmidt, R.; Working Group On Machine Protection

    2005-06-01

    At top energy (proton momentum 7 TeV/c) with nominal beam parameters, each of the two LHC proton beams has a stored energy of 350 MJ threatening to damage accelerator equipment in case of accidental beam loss. It is essential that the beams are properly extracted onto the dump blocks in case of failure since these are the only elements that can withstand full beam impact. Although the energy stored in the beams at injection (450 GeV/c) is about 15 times smaller compared to top energy, the beams must still be properly extracted in case of large accidental beam losses. Failures must be detected at a sufficiently early stage and initiate a beam dump. Quenches and power converter failures will be detected by monitoring the correct functioning of the hardware systems. In addition, safe operation throughout the cycle requires the use of beam loss monitors, collimators and absorbers. Ideas of detection of fast beam current decay, monitoring of fast beam position changes and monitoring of fast magnet current changes are discussed, to provide the required redundancy for machine protection.

    Full Text Available Uma paciente de 4 meses de idade foi encaminhada ao hospital por aumento de volume abdominal, cianose e febre há dois meses. Ao exame, apresentou hepatoesplenomegalia. Com os resultados laboratoriais constatou-se anemia hipocrômica microcítica, leucocitose, plaquetopenia e provas de função hepática alteradas. Levantou-se a hipótese de erros inatos do metabolismo. A paciente evoluiu desfavoravelmente e foi a óbito. À necropsia o fígado apresentou-se cirrótico e com grande depósito de ferro no parênquima. O diagnóstico anatomopatológico foi hemocromatose hereditária, no entanto os resultados laboratoriais confirmaram tirosinemia tipo 1. Tanto a hemocromatose primária quanto a tirosinemia evoluem com cirrose hepática, sendo que a segunda pode ocasionalmente levar ao depósito de ferro do tipo hemocromatose secundária, o que dificulta muito a diferenciação entre elas com bases puramente anatomopatológicas, acarretando, assim, um diagnóstico errôneo de hemocromatose hereditária. Esse diagnóstico diferencial muitas vezes só é possível com os achados de rastreamento de erros inatos do metabolismo.A 4-month-old female patient was taken to hospital due to increase in abdominal volume, cyanosis and fever for two months. At examination, she presented hepatosplenomegaly. Laboratory tests revealed hypochromic anemia (due to iron deficiency, leucocytosis, low platelet count and altered hepatic functions. Innate metabolic error was suspected. Follow-up developed unfavorably and she died. At necropsy, the liver was cirrhotic, with large iron deposits in the parenchyma. Necropsy diagnosis was haemochromatosis, and laboratorial results confirmed type 1 tyrosinemia. Either primary haemochromatosis or tyrosinemia could cause hepatic cirrhosis. Tyrosinemia may also cause iron deposits in the liver parenchyma, similar to those observed in secondary haemochromatosis. Such facts can make differential diagnosis difficult between these and

    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.

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

    The fundamental mechanism of the bound states in the continuum is the full destructive interference of two resonances when two eigenlevels of the closed system are crossing. There is, however, a wide class of quantum chaotic systems which display only avoided crossings of eigenlevels. As an example of such a system we consider the Sinai billiard coupled with two semi-infinite waveguides. We show that notwithstanding the absence of degeneracy bound states in the continuum occur due to accidental decoupling of the eigenstates of the billiard from the waveguides. - Highlights: • Bound states in the continuum in open chaotic billiards occur to accidental vanishing of coupling of eigenstate of billiard with waveguides.

    Full Text Available Aim: Carbon monoxide (CO is often referred to as the “silent killer” because its victims cannot see it, smell it or taste it. CO is responsible for a large percentage of the accidental poisonings and deaths reported throughout the world. CO poisoning therefore is considered a serious global health threat. The aim of the present study was to describe the cases of CO poisoning in a rural areas of Adana, Turkey between 2002 and 2015 based on data collected from incident reports. Methods: The cases of accidental CO poisoning were statistically analyzed. During that period, 74 incidents occurred and 154 people were poisoned by accidental CO poisoning. Results: The results of this analysis indicate that men and adults aged ≥65 years were more likely to die from CO poisoning than others. The number of CO poisoning cases was highest during the heating season. The majority (72% of poisoning resulting in hospitalization with a life-threatening condition or death occurred within the home. Conclusion: CO poisoning is a serious danger. People must be informed about this hazard. By educating risk groups about the dangers of CO poisoning, it is possible to save many lives as well as reduce the health risks.

  17. Accidental outcomes guide punishment in a "trembling hand" game.

    Directory of Open Access Journals (Sweden)

    Fiery Cushman

    Full Text Available How do people respond to others' accidental behaviors? Reward and punishment for an accident might depend on the actor's intentions, or instead on the unintended outcomes she brings about. Yet, existing paradigms in experimental economics do not include the possibility of accidental monetary allocations. We explore the balance of outcomes and intentions in a two-player economic game where monetary allocations are made with a "trembling hand": that is, intentions and outcomes are sometimes mismatched. Player 1 allocates $10 between herself and Player 2 by rolling one of three dice. One die has a high probability of a selfish outcome, another has a high probability of a fair outcome, and the third has a high probability of a generous outcome. Based on Player 1's choice of die, Player 2 can infer her intentions. However, any of the three die can yield any of the three possible outcomes. Player 2 is given the opportunity to respond to Player 1's allocation by adding to or subtracting from Player 1's payoff. We find that Player 2's responses are influenced substantially by the accidental outcome of Player 1's roll of the die. Comparison to control conditions suggests that in contexts where the allocation is at least partially under the control of Player 1, Player 2 will punish Player 1 accountable for unintentional negative outcomes. In addition, Player 2's responses are influenced by Player 1's intention. However, Player 2 tends to modulate his responses substantially more for selfish intentions than for generous intentions. This novel economic game provides new insight into the psychological mechanisms underlying social preferences for fairness and retribution.

    XOQ DW code is currently used to assess the atmospheric dispersion for the routine releases of radioactive gaseous effluents at Yonggwang nuclear power plants. This code was developed based on XOQDOQ code and an additional code is required to assess the atmospheric dispersion for potential accidental releases. In order to assess the atmospheric dispersion for the accidental releases, XOQAR code has been developed by using PAVAN code that is based on Reg. Guide 1.145. The terrain data of XOQ DW code inputs and the relative concentrations (X/Q) of XOQ DW code outputs are used as the inputs of the XOQAR code through the interface with XOQ DW code. By using this code, the maximum values of X/Q at exclusion area and low population zone boundaries except for sea areas were assessed as 1.33 x 10 -4 and 7.66 x 10 -6 sec/m 3 , respectively. Through the development of this code, a code system is prepared for assessing the atmospheric dispersion for the accidental releases as well as the routine releases. This developed code can be used for other domestic nuclear power plants by modifying the terrain input data

    Full Text Available The helideck structure must satisfy the safety requirements associated with various environmental and accidental loads. Especially, there have been a number of fire accidents offshore due to helicopter collision (take-off and/or landing in recent decades. To prevent further accidents, a substantial amount of effort has been directed toward the management of fire in the safety design of offshore helidecks. The aims of this study are to introduce and apply a procedure for quantitative risk assessment and management of fires by defining the fire loads with an applied example. The frequency of helicopter accidents are considered, and design accidental levels are applied. The proposed procedures for determining design fire loads can be efficiently applied in offshore helideck development projects.

    To identify the risks factors for new accidental falls in elderly patients attended in the Traumatology Ambulatory of a University hospital in Rio Grande do Sul, Brazil. Quantitative study of the type of multiple cases. Performed at the traumatology ambulatory, amongst fifteen elders that attended the inclusion criteria: age of sixty or more; patient at the traumatology ambulatory because of a fall motivated by accident, oriented and in conditions of answer an interview of data collectors. The data collection was made between April and June, 2013, with the Elderly Nursing Core Set scale (Lopes & Fonseca). The data analysis was made by a descriptive structure, which helped identify the existence of relation patterns among the cases. The risk factors for new accidental falls identified with larger incidence amongst the elders studied were: impaired balance (15/15), age above 65 (11/15), use of antihypertensive drugs (9/15), absence of non-slip material at home environment (7/15), in seven cases; rugs scattered at the floor of the house (6/15). The combination of intrinsic and extrinsic factors that include the environmental risks is considered a much more relevant cause to occur the new falls. The minimization of the home dangers, allied to the control of the elder intrinsic factors, may reduce the risks of causes. In that sense, is necessary that the nursing team make available more attention to the elderly assisted at the ambulatories, mainly those with sequelae due to fall accidents.

    Objective: To study the typing and AT II receptor inhibitor therapy for essential hypertension (EH) patients. Methods: Plasma RA, AT II and NPY levels were measured by radioimmunoassay (RIA) in 208 Patients with EH and 100 controls; plasma NPY levels were measured in 40 EH patients before and after AT II receptor inhibitor therapy. The mean coefficient of variation for intra and inter batch-assay were less than 10% and 15% respectively. Results: In 208 EH patients plasma PRA levels were increased, normal and decreased in 17.8%, 71.6% and 10.6% respectively, while in 128 EH patients Plasma AT II levels were increased, normal and decreased in 20.3%, 64.1% and 15.6% respectively. In 69 EH Plasma NPY levels were significantly higher than those in 40 control subjects. (17 grade I EH, 137.3 +- 32.6 pg/mL; 28 grade II EH, 148.5 +- 41.1 pg/mL; 24 grade III EH, 162.4 +- 42.7 pg/mL; 40 controls, 118.5 +- 30.5 pg/mL). In 40 EH patients plasma NPY levels were decreased after AT II receptor inhibitor therapy as the blood pressure decreased. Conclusion: Typing of EH patients according to levels of plasma PRA and AT II is useful in guiding treatment. AT II receptor inhibitors are indicated in those patients with increased plasma levels and NPY levels can be used for appraisal of the treatment efficacy

    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 lead to the 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 1-D 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. (author)

    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

    Full Text Available Resumo Partindo do pressuposto de que a memória é um dos fundamentos da literatura, o artigo compara Leite derramado, de Chico Buarque, com Memórias póstumas de Brás Cubas, de Machado de Assis. A análise explicita semelhanças e diferenças entre esses romances memorialísticos, relativas a aspectos temáticos e composicionais, e comprova que ambos compõem uma alegoria da nacionalidade brasileira, estabelecendo um paralelismo entre o percurso da vida dos protagonistas, ou de sua família, e episódios da história do Brasil. Conclui que os procedimentos criativos das narrativas compõem um jogo de espelhos que, ao envolver o leitor, reivindica a importância da literatura como espaço de reflexão sobre si mesma e sobre acontecimentos da história, os quais a ficção projeta sob nova luz.

    Pádua, I; Moreira, A; Moreira, P; Barros, R

    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.

Por tal motivo, el propósito de este artículo es analizar las causas y consecuencias de los accidentes laborales ocurridos durante el segundo semestre del año 2012 en dos proyectos de construcción de Neiva, Colombia. El alcance fue de tipo documental considerando como fuente de información los soportes de los accidentes laborales reportados ante la Administradora de Riesgo Laborales (ARL; para determinar las causas que dieron origen a dichos accidentes se utilizó el modelo de Frank E. Bird. Se analizaron 117 accidentes en los que se identificaron 195 faltas de control, 136 factores personales, 112 factores del trabajo, 151 actos inseguros y 54 condiciones inseguras; lo anterior teniendo en cuenta que en algunos accidentes se presentaron más de una causa. De esta manera se concluye que el mayor porcentaje de accidentes de trabajo, ha sido generado por faltas de control seguidos por actos inseguros. Por tal motivo se recomienda la realización de programas de gestión de riesgos prioritarios, basados en una adecuada identificación de peligros, que permitan mitigar y controlar los riesgos, desarrollando a la vez en los trabajadores una cultura de autocuidado

    A unique case of accidental hanging due to compression of the neck of an adult by the branches of a coffee tree is reported. The decedent was a 42-year-old male who was found dead in a semi prone position on a slope. His neck was lodged in a wedge formed by two branches of a coffee tree, with his legs angled downwards on the slope. Autopsy revealed two friction abrasions located horizontally on either side of the front of the neck, just above the larynx. The findings were compatible with compression of the neck by the branches of the tree, with the body weight of the decedent contributing to compression. Subsequent complete autopsy examination confirmed the cause of death as hanging. Following an inquest the death was ruled to be accidental.

    Full Text Available História e memória não são duas noções que podem sobrepor-se exatamente e isto tanto menos quanto o passado do qual elas dão conta traz a marca de um traumatismo da história. No coração das relações desarmônicas que têm Clio e Mnemósine, guarda-se o arquivo. Em semelhante caso, o tratamento do qual este é objeto constitui de modo incontestável um observatório das inumeráveis implicações que a rememoração do passado suscita. Se alguns duvidam dessa verdade, os trabalhos e ensaios franceses dos quais este artigo propõe a síntese o ilustram eloquentemente. Eles mostram, em contraposição às ambições que o arquivo suscita, o poder que nossas representações ocidentais imputam à sua posse. Alvo de uma violência de outro gênero, o arquivo negligenciado nutre polêmicas a favor das quais variam as alianças e se movem linhas de ruptura. Sobre o tabuleiro da memória, militantes, historiadores profissionais, políticos, legisladores e juízes jogam um jogo complicado, do qual, a contar dos anos 1980, participam as testemunhas assim como os historiadores provindos das fileiras das comunidades memoriais.

Memórias dominadas e dominantes, vitimárias e heroicas, subjetivas e objetivas, memórias do coração e da razão se opõem em um estrépito cujos solavancos afetam infalivelmente a disciplina histórica.

    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.

    This study stemmed from the data gathered by a research conducted by the coordinator of the Department of Healthcare Services and a group of nurses involved in a research on accidental falls in hospitalized children at the "G. Gaslini" Children's Hospital and Scientific Research Institute in Genoa, Italy. The first retrospective study evaluated the accidental falls in hospitalized children referred to the three-year period 2003-2006, while the second perspective study, referred to the trimester March-May 2007, found that the main cause of falls in children was parent's distraction. The method adopted in the first phase of our study was a proactive risk analysis (The Basics of Healthcare Failure Mode and Effect Analysis), identified in the first place by the VA National Centre for Patient Safety and applied to the "Child and parent hospital admission process". This proactive risk analysis has proven to be very effective in preventing the risk of accidental falls in hospitalized children through effective communication and educational interventions. The second phase of our study consisted of two Focus Groups for accidental traumatic events. The analysis of the results of the study showed how effective communication is instrumental, not only to have a better awareness of the children and their parents during their stay in hospital, but also to implement educational sessions on prevention to reduce the risk of accidental traumatic events. The present study contributes to improve safety and the quality of care by motivating nurses to keep their attention high on falls in hospitalized children, by monitoring and the development of new risk assessment tools.

    This study explores and describes factors that persons with multiple sclerosis (MS) perceive as being related to accidental falls. A qualitative content analysis with primarily deductive approach was conducted using the International Classification of Functioning, Disability and Health. Twelve persons with MS, and identified as fallers, were interviewed. Factors perceived to cause accidental falls that had not previously been targeted in MS populations in relation to falls were identified as divided attention, reduced muscular endurance, fatigue and heat sensitivity. Previously reported risk factors such as changed gait pattern, limited walking ability, impaired proprioception, vision and spasticity were supported. Activities involving walking, recreation and leisure, maintaining and changing body position, lifting or carrying, taking care of the home, washing the body, moving around, preparing meals and housekeeping were limited and considered to be risk activities. Supportive persons and assistive device reduced falls, and unsuitable physical environments and climate conditions induced falls. Several preventative strategies were described as partially compensating for the impairments, limitations and restrictions. Investigating accidental falls using the perspective of the patient gave important information about variables not earlier targeted in MS research.

    Positron emission mammography (PEM) has begun to show promise as an effective method for the detection of breast lesions. Due to its utilization of tumor-avid radiopharmaceuticals labeled with positron-emitting radionuclides, this technique may be especially useful in imaging of women with radiodense or fibrocystic breasts. While the use of these radiotracers affords PEM unique capabilities, it also introduces some limitations. Specifically, acceptance of accidental and Compton-scattered coincidence events can decrease lesion detectability. The authors studied the effect of accidental coincidence events on PEM images produced by the presence of /sup 18/F-Fluorodeoxyglucose in the organs of a subject using an anthropomorphic phantom. A delayed-coincidence technique was tested as a method for correcting PEM images for the occurrence of accidental events. Also, a Compton scatter correction algorithm designed specifically for PEM was developed and tested using a compressed breast phantom. Finally, the effect of object size on image counts and a correction for this effect were explored. The imager used in this study consisted of two PEM detector heads mounted 20 cm apart on a Lorad biopsy apparatus. The results demonstrated that a majority of the accidental coincidence events (/spl sim/80%) detected by this system were produced by radiotracer uptake in the adipose and muscle tissue of the torso. The presence of accidental coincidence events was shown to reduce lesion detectability. Much of this effect was eliminated by correction of the images utilizing estimates of accidental-coincidence contamination acquired with delayed coincidence circuitry built into the PEM system. The Compton scatter fraction for this system was /spl sim/14%. Utilization of a new scatter correction algorithm reduced the scatter fraction to /spl sim/1.5%. Finally, reduction of count recovery due to object size was measured and a correction to the data applied. Application of correction techniques

    Full Text Available Objective. To identify the risks factors for new accidental falls in elderly patients attended in the Traumatology Ambulatory of a University hospital in Rio Grande do Sul, Brazil. Methodology. Quantitative study of the type of multiple cases. Performed at the traumatology ambulatory, amongst fifteen elders that attended the inclusion criteria: age of sixty or more; patient at the traumatology ambulatory because of a fall motivated by accident, oriented and in conditions of answer an interview of data collectors. The data collection was made between April and June, 2013, with the Elderly Nursing Core Set scale (Lopes & Fonseca. The data analysis was made by a descriptive structure, which helped identify the existence of relation patterns among the cases. Results. The risk factors for new accidental falls identified with larger incidence amongst the elders studied were: impaired balance (15/15, age above 65 (11/15, use of antihypertensive drugs (9/15, absence of non-slip material at home environment (7/15, in seven cases; rugs scattered at the floor of the house (6/15. Conclusion. The combination of intrinsic and extrinsic factors that include the environmental risks is considered a much more relevant cause to occur the new falls. The minimization of the home dangers, allied to the control of the elder intrinsic factors, may reduce the risks of causes. In that sense, is necessary that the nursing team make available more attention to the elderly assisted at the ambulatories, mainly those with sequelae due to fall accidents.

    How do people respond to others' accidental behaviors? Reward and punishment for an accident might depend on the actor's intentions, or instead on the unintended outcomes she brings about. Yet, existing paradigms in experimental economics do not include the possibility of accidental monetary allocations. We explore the balance of outcomes and intentions in a two-player economic game where monetary allocations are made with a “trembling hand”: that is, intentions and outcomes are sometimes mismatched. Player 1 allocates $10 between herself and Player 2 by rolling one of three dice. One die has a high probability of a selfish outcome, another has a high probability of a fair outcome, and the third has a high probability of a generous outcome. Based on Player 1's choice of die, Player 2 can infer her intentions. However, any of the three die can yield any of the three possible outcomes. Player 2 is given the opportunity to respond to Player 1's allocation by adding to or subtracting from Player 1's payoff. We find that Player 2's responses are influenced substantially by the accidental outcome of Player 1's roll of the die. Comparison to control conditions suggests that in contexts where the allocation is at least partially under the control of Player 1, Player 2 will punish Player 1 accountable for unintentional negative outcomes. In addition, Player 2's responses are influenced by Player 1's intention. However, Player 2 tends to modulate his responses substantially more for selfish intentions than for generous intentions. This novel economic game provides new insight into the psychological mechanisms underlying social preferences for fairness and retribution. PMID:19707578

    The shutter on one of the windows of an X-ray diffraction apparatus was accidentally left open, exposing the worker to the radiation. The worker was wearing a dosimeter film, which was processed immediately to evaluate the potential risk. It was determined that the exposure rate was 350 Roentgen/minute on the skin surface, with corrections being made for the worker's thin clothing. It was concluded that in spite of the worker receiving a relative high dose, it did not reach the threshold value for producing deterministic effects such as cataracts, erythema, and skin damage

    Cannabis intoxication in toddlers is rare and mostly accidental. Our objectives were to focus on the characteristics and management of children under the age of 6 years who were admitted to our emergency department with cannabis poisoning reported as accidental by parents, and to point out the need to consider accidental cannabis ingestions as an indicator of neglect. The medical records of children hospitalized for cannabis poisoning in a pediatric emergency department from January 2007 to November 2012 were retrospectively evaluated. Data collected included age, sex, drug ingested, source of drug, intentional versus accidental ingestion, pediatric intensive care unit or hospital admission, treatment and length of hospital stay, toxicology results, and rate of child protectives services referral. Twelve toddlers (4 boys and 8 girls; mean age, 16.6 months) were included. All had ingested cannabis. Their parents reported the ingestion. Seven children experienced drowsiness or hypotonia. Three children were given activated charcoal. Blood screening for cannabinoids, performed in 2 cases, was negative in both, and urine samples were positive in 7 children (70%). All children had favorable outcomes after being hospitalized from 2 to 48 hours. Nine children were referred to social services for further assessment before discharge. Cannabis intoxication in children should be reported to child protection services with the aim of prevention, to detect situations of neglect and at-risk families. Legal action against the parents may be considered. Accidental intoxication and caring parents should be no exception to this rule.

    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.

    The two types of fuel rods with different pellet shaped, i.e. flat pellets and dished pellets, were tested in the NSRR to investigate the effects of pellet shapes on the fuel failure behavior under an RIA condition and the results were compared with those of the chamfered pellet fuel rods which are used as the reference rod in the NSRR experiments. In addition, the deformation of pellets due to thermal expansion is calculated by using an FEM computer code. Through the above results, following conclusions are obtained. (1) In the experiments, insignificant differences on the cladding surface temperature responses and the appearance of post-irradiated rods are observed in each type of rods. (2) Evident differences on the deformation of fuel pellets have not appeared in the calculation. (3) In the RIA conditions, it is concluded that the fuel failure behavior and threshold energy might not be affected by pellet shape of which size is in the range of the current LWR's fuel rods.

    2009-01-01

    Uranium Hexafluoride is a material used in the various processes which comprise the front end of the nuclear fuel cycle (conversion, enrichment and fuel fabrication). Confinement of UF 6 is a very important safety requirement since this material is highly reactive and presents safety hazards to humans. The present paper discusses the safety relevant aspects of accidental releases of UF 6 inside process confinement buildings. Postulated accidental scenarios are analyzed and their consequences evaluated. Implant releases rates are estimated using computer code predictions. A time dependent homogeneous compartment model is used to predict concentrations of UF 6 , hydrogen fluoride and uranyl fluoride inside a confinement building, as well as to evaluate source terms released to the atmosphere. These source terms can be used as input to atmospheric dispersion models to evaluate consequences to the environment. The results can also be used to define adequate protective measures for emergency situations. (author)

    Full Text Available Acute toxicity is a frequent but avoidable cause of morbidity and mortality in children especially in developing countries, including India. Present study assesses their pattern with relation to different age groupings. This retrospective study was conducted among all hospitalised paediatric victims of acute accidental poisoning at the King George Medical University; Lucknow during 2010 -11. Their history, baseline characteristics, clinical course and outcome was studied. Most children were male of less than three years with 4% overall mortality. Kerosene oil was implicated in most cases. Childhood poisoning is commonest during 1-3 years with a male preponderance. Household poisons; especially kerosene oil was responsible for most cases which was consumed accidentally. Parents must be educated and warned to keep these toxic ingredients safely in suitable containers and out of reach of their beloved children.

  13. [The accidental detection of apical periodontitis].

    Wesselink, P R

    2011-04-01

    Accidental detection of an asymptomatic apical periodontitis raises the question whether this lesion should be treated or not. Arguments favouring treatment are that the inflammation may cause pain in the future, may enlarge or may negatively affect the host's resistance. Reasons for not treating may be that treatment weakens the tooth, may cause iatrogenic damage and that treatment is expensive and burdensome for the patient and does not lead in all cases to complete healing. Scientific evidence supporting either choice, whether treating the lesion or not, is lacking. In making such decisions, therefore, personal judgments by the patient and the dentist concerning the impact on the quality of life of the patient play an important role.

    Unintentional injuries are the leading cause of death in children around the world and are an under-recognized public health problem in the United States. The purpose of this study was to highlight the nature of the problem in South Dakota and outline interventions that have been successful in reducing childhood injuries in other states. This quantitative retrospective study examined mortality files in South Dakota for children birth to 19 years of age who died between January 1, 2000 to December 28, 2007. Although the number of deaths declined considerably from 2006 to 2007, South Dakota had the second-highest rate in the nation of childhood unintentional injury deaths from all causes between 2000-2005. The majority of deaths occurred in males and were associated with transportation-related deaths. Suffocation was the leading cause of death for newborns to age 1 year. Childhood accidental death in South Dakota is clearly a critical public health problem. Intervention efforts to reduce deaths from unintentional injuries amongst children should be targeted as the leading causes of accidental death for specific age groups and American Indian youth. Physicians, health educators and policymakers must play a role in prevention targeting the high-risk groups in addition to advocating for policy changes to protect childhood safety. More stringent child restraint laws, graduated driving laws, smoking cessation programs for parents, creation of safer sleep environments and further investigation of why a high proportion of American Indian children die accidentally in South Dakota are all warranted.

    2002-01-01

    The analysis of accidental sequences associated with the Containment is one of the most important tasks during the development of the Probabilistic Safety Assessment (PSA) of nuclear plants mainly because of its importance on the mitigation of consequences of severe postulated accident initiating events. This paper presents a first approach of the Containment analysis of the INAP identifying failures and events that can compromise its performance, and outlining accidental sequences and Containment end states. The initial plant damage states, which are the input for this study, are based on the event trees developed in the PSA level 1 for the INAP. It should be emphasized that since this PSA is still in a preliminary stage it is subjected to further completion. Consequently, the Containment analysis shall also be revised in order to incorporate, in an extension as complete as possible, all initial plant damage states, the corresponding event trees, and the related Containment end states. Finally, it can be concluded that the evaluation of the qualitative analysis presented herein allows a concise and broad knowledge of the qualitative analysis presented herein allows a concise and broad knowledge of the development of accidental sequences related to the Containment of the INAP.

    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.

    Full Text Available As vilas operárias foram a materialização habitacional da política higienista promovida pelos governos para a transformação das cidades - novos padrões funcionais e formais. O processo de industrialização foi propulsor dessas alterações em busca de um habitat operário compatível com as necessidades básicas de reprodução da força de trabalho. A participação de médicos e engenheiros sanitaristas norteou as reformas urbanas. Em Vitória o engenheiro Saturnino de Brito projetou o “Novo Arrabalde” em 1896 onde previu duas vilas operárias. A construção de moradia para os empregados remete ao período da escravidão, porém na cidade as vilas operárias estão relacionadas ao período industrial e como o café permaneceu por mais tempo como principal produto da economia capixaba as vilas surgiram a partir da primeira década do século XX. Em Vitória a formação de cortiços foi tímida e não houve corrida no início do século passado por habitação na região central. O aterro e loteamento do Campinho, concluído em 1912 e a construção de vinte e oito casas para funcionários estatais em suas imediações foram às primeiras iniciativas do governo relacionadas à habitação operária na cidade. As vilas operárias em Vitória, suas causas e simbolismos são análises que o presente trabalho propõe-se realizar

    This report presents the comparisons between calculated and measured fuel rod behavior and the analysis of stress for preirradiated LWR type fuel rods during reactivity initiated accident (RIA) conditions. For the calculations, FPRETAIN computer code which can simulate the fuel behavior under RIA conditions at extended burnup stage was used. For the experimental, data obtained from the Special Power Excursion Reactor Test (SPERT) and the Power Burst Facility (PBF) tests were used. The results of the comparisons showed that the FPRETAIN code predicted well the tendency of the fuel rod behavior during RIA. From the results of the stress analysis, it was found that the maximum hoop stress of cladding was not proportional to the energy deposition of fuel rod. Calculated cladding maximum hoop stress of failed fuel at high burnup was not lower than that of intact fresh or low burnup fuel. (author)

    Full Text Available Neste artigo, desenvolve-se a argumentação de que a escrita da história de cidades elaborada por meio do diálogo entre a memória e a História pode oferecer possibilidades de aprendermos a nelas nos perder para nelas nos reencontrar, num tempo labirintítico. A idéia do labirinto é inspirada em Walter Benjamin (1985, 1994 e em outros que trabalham nessa tradição teórica e representa uma contraposição à compreensão do tempo histórico forjado na modernidade. Enquanto este é linear, vazio, homogêneo, o tempo labirintítico é múltiplo, não-linear, repleto de possibilidades inscritas nas relações do presente com passado e futuro. Para decifrá-lo, é necessária a aprendizagem da leitura indiciária - dos sinais, dos signos, das ruínas, das marcas, dos gestos, dos silêncios, - deixados pela ação dos homens e relatados pelos seus testemunhos. É, também, em Benjamin que se apóia a idéia de que a história como labirinto é contada pelo narrador que narra a sua experiência histórica. A escrita híbrida da história - entre a História e a memória -, base para o desenvolvimento da referida argumentação, é fruto de uma pesquisa com fontes orais e outros conhecimentos históricos, elaborada para uma dissertação de mestrado defendida pela autora do artigo, sobre a história de Governador Valadares, Minas Gerais.In this article, it is developed an argumentation concerning the writing of the history of the cities being elaborated through the dialogue between the memory and the History. This argumentation is based on the idea of this kind of writing offer possibilities of learning to lose ourselves inside the memory and the History and to find ourselves again through them, in a labyrinth time. The idea of the labyrinth is inspired in Walter Benjamim (1985,1994 as well in others who work in this theoretical line. It represents a counter-position to the understanding of historical time constructed in modern time. While the

A case of BiTine ring ingestion is presented with a note on inefficient ring separation forceps.Case description: A 28-year-old male patient accidentally ingested the BiTine ring (2 cm diameter, 0.5 cm outward projections while it was being applied to a distoproximal cavity in tooth # 19. The ring placement forceps were excessively flexible; bending of the beaks towards the ring combined with a poor no-slippage mechanism led to sudden disengagement of the ring and accelerated movement towards the pharynx. We followed the patient with bulk forming agents and radiographs. Fortunately the ring passed out without any complications.Clinical implications: Checking equipment and methods is as important as taking precautions against any preventable medical emergency. It is the responsibility of the clinician to check, verify and then use any instrument/equipment.Keywords: foreign bodies/radiography, foreign bodies/complications, equipment failure, dental instrument, accidental ingestion

La muestra estuvo constituida por 135 familias, que tuviesen como característica la presencia en ella de un niño entre 0 y 15 años y/o un anciano (+ 60 años. La información se obtuvo mediante la observación directa del hogar, entrevista con los pobladores para determinar el tipo de potencial de riesgo existente en el hogar. Se utilizó el método de la Estadística Descriptiva. Se encontró que el 45.5 % de los hogares posee riesgos de accidentes, y el tipo de potencial de riesgo encontrado se relaciona con la corriente eléctrica. Los medios de difusión masiva son la principal vía de obtención de la información. El mayor por ciento de potencial de riesgo de accidente por corriente eléctrica se reporta por tomacorrientes sin tapas y en mal estado.The word accident, according to its usual meaning, is defined as a casual event, but indeed it is not always due to chance or hazard.

    Veratrum album (white or false hellebore) is a poisonous plant containing steroidal alkaloids that cause nausea, vomiting, headache, visual disturbances, paresthesia, dizziness, bradycardia, atrioventricular block, hypotension, and syncope. It is regularly mistaken for Gentiana lutea (yellow gentian). We report accidental poisoning with V. album mistaken for Allium ursinum (wild garlic), a wild plant used in soups and salads in Central Europe. Four adults (24-45 years) accidentally ingested V. album mistaken for A. ursinum in self-prepared salads and soups. Within 15-30 min of ingestion they developed nausea, vomiting, and abdominal pain. At the same time dizziness, tingling, dimmed and jumping vision, transient blindness, and confusion appeared. On arrival at the ED, all patients had sinus bradycardia and hypotension. Following treatment the patients were discharged well 24-48 h after ingestion. In patients presenting with gastrointestinal, neurological, and cardiovascular symptoms a history of wild plant ingestion suggests possible poisoning with V. album mistaken for wild garlic.

    The acute radiation syndrome has been characterized in different ways that involve risk for life and health of the people overexposed to ionizing radiations. This work intends to test a therapeutical total body irradiation (TBI) model as conditioning to bone marrow transplantation. With the purpose of evaluating the applicability of several biological indicators in accidental overexposures, a study was carried out in 46 patients undergoing TBI receiving doses between 10 Gy and 12 Gy. The following parameters were assessed: lipo peroxyde plasmatic levels (TBARS) and total plasma antioxidant activity, reticulocyte maturity index (RMI) and charges in lymphocyte subpopulations. These data suggest that TBARS could provide an useful evolutive indicator in accidental overexposed patients and RMI is an early indicator of bone marrow recovery after radioinduced aplasia

  16. Principles of RIA data management

    Chase, G.D.

    1983-01-01

    The ultimate objective of an RIA is to correlate observed values of radioactivity with observed clinical manifestations that may indicate the existence of a particular disease or metabolic malfunction. To achieve this objective, a two-step process may be considered. First, it is necessary to measure the concentration of a particular chemical entity, the analyte, in the sample presented for analysis. In most cases the analyte is a drug, hormone, or vitamin, or another well-defined chemical substance of known structure and molecular weight. The principal responsibility for measuring the analyte concentration rests with the clinical chemist performing the assay. Second, it is necessary to interpret the assay results in the light of patient history and clinical observations. The principal responsibility for this step lies with the clinician. In this paper, only the first step, the RIA, is considered. Although RIAs in particular are discussed, many of the topics considered apply equally well to radioassays in which the specific binder is not an antibody and to immunoassays in which the tag is not a radioisotope

    PurposeTo report OCT appearance and surgical outcomes of full-thickness macular holes (MHs) accidentally caused by laser devices.Patients and methodsThis retrospective case series included 11 eyes of 11 patients with laser-induced MHs treated by pars plana vitrectomy, internal limiting membrane (ILM) peeling, and gas or silicone oil tamponade. Evaluations included a full ophthalmic examination, macular spectral-domain optical coherence tomography (SD-OCT), and fundus photography. Main outcome measures is MH closure and final visual acuity; the secondary outcome was the changes of retinal pigment epithelium and photoreceptor layer evaluated by sequential post-operative SD-OCT images.ResultsFive patients were accidentally injured by a yttrium aluminum garnet (YAG) laser and six patients by handheld laser. MH diameters ranged from 272 to 815 μm (mean, 505.5±163.0 μm) preoperatively. Best-corrected visual acuity (BCVA) improved from a mean of 0.90 logMAR (range, counting finger-8/20) preoperatively to a mean of 0.34 logMAR (range, a counting finger-20/20) postoperatively (P=0.001, t=4.521). Seven of 11 patients (63.6%) achieved a BCVA better than 10/20. Ten patients had a subfoveal hyperreflectivity and four patients had a focal choroidal depression subfoveal preoperatively. At the last follow-up, all 11 eyes demonstrated the following: closure of the macular hole, variable degrees of disruption of external limiting membrane (ELM) and outer photoreceptor ellipsoid and interdigitation bands. In 10 eyes, the disruption was in the form of focal defects in the outer retina. After surgery, the subfoveal hyperreflectivity and focal choroidal depression remained.ConclusionAccidental laser-induced full-thickness macular holes can be successfully closed with surgery. Inadvertent retinal injury from laser devices, especially handheld laser injury has occurred with increasing frequency in recent years. However, there is a paucity of data regarding these types of injuries

    Reactivity-initiated accident (RIA) fuel rod codes have been developed for a significant period of time and they all have shown their ability to reproduce some experimental results with a certain degree of adequacy. However, they sometimes rely on different specific modelling assumptions the influence of which on the final results of the calculations is difficult to evaluate. The NEA Working Group on Fuel Safety (WGFS) is tasked with advancing the understanding of fuel safety issues by assessing the technical basis for current safety criteria and their applicability to high burnup and to new fuel designs and materials. The group aims at facilitating international convergence in this area, including the review of experimental approaches as well as the interpretation and use of experimental data relevant for safety. As a contribution to this task, WGFS conducted a RIA code benchmark based on RIA tests performed in the Nuclear Safety Research Reactor in Tokai, Japan and tests performed or planned in CABRI reactor in Cadarache, France. Emphasis was on assessment of different modelling options for RIA fuel rod codes in terms of reproducing experimental results as well as extrapolating to typical reactor conditions. This report provides a summary of the results of this task. (authors)

    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

    The incidence of hypothermia is difficult to evaluate, and the data concerning the morbidity and mortality rates do not seem to fully represent the problem. The aim of the study was to estimate the actual prevalence of accidental hypothermia in Poland, as well as the methods of diagnosis and management procedures used in emergency rooms (ERs). A specially designed questionnaire, consisting of 14 questions, was mailed to all the 223 emergency rooms (ER) in Poland. The questions concerned the incidence, methods of diagnosis and risk factors, as well as the rewarming methods used and available measurement instruments. The analysis involved data from 42 ERs providing emergency healthcare for the population of 5,305,000. The prevalence of accidental hypothermia may have been 5.05 cases per 100.000 residents per year. Among the 268 cases listed 25% were diagnosed with codes T68, T69 or X31, and in 75% hypothermia was neither included nor assigned a code in the final diagnosis. The most frequent cause of hypothermia was exposure to cold air alongside ethanol abuse (68%). Peripheral temperature was measured in 57%, core temperature measurement was taken in 29% of the patients. Peripheral temperature was measured most often at the axilla, while core temperature measurement was predominantly taken rectally. Mild hypothermia was diagnosed in 75.5% of the patients, moderate (32-28°C) in 16.5%, while severe hypothermia (less than 28°C) in 8% of the cases. Cardiopulmonary resuscitation was carried out in 7.5% of the patients. The treatment involved mainly warmed intravenous fluids (83.5%) and active external rewarming measures (70%). In no case was extracorporeal rewarming put to use. The actual incidence of accidental hypothermia in Polish emergency departments may exceed up to four times the official data. Core temperature is taken only in one third of the patients, the treatment of hypothermic patients is rarely conducted in intensive care wards and extracorporeal rewarming

    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.

    Among the main causes of death in our country are car accidents, drowning and accidental burns. Strangulation is a potentially fatal injury and an important cause of homicide and suicide among adults and adolescents. In children, its occurrence is usually accidental. However, in recent years, several cases of accidental strangulation in children around the world have been reported. A 2-year-old male patient was strangled in a car window. The patient was admitted to the pediatric intensive care unit with a Glasgow Coma Scale score of 8 and presented with progressive worsening of respiratory dysfunction and torpor. The patient also presented acute respiratory distress syndrome, acute pulmonary edema and shock. He was managed with protective mechanical ventilation, vasoactive drugs and antibiotic therapy. He was discharged from the intensive care unit without neurological or pulmonary sequelae. After 12 days of hospitalization, he was discharged from the hospital, and his state was very good. The incidence of automobile window strangulation is rare but of high morbidity and mortality due to the resulting choking mechanism. Fortunately, newer cars have devices that stop the automatic closing of the windows if resistance is encountered. However, considering the severity of complications strangulated patients experience, the intensive neuro-ventilatory and hemodynamic management of the pathologies involved is important to reduce morbidity and mortality, as is the need to implement new campaigns for the education of parents and caregivers of children, aiming to avoid easily preventable accidents and to optimize safety mechanisms in cars with electric windows.

    Full Text Available Forrageiras rústicas, como as braquiárias, são predominantes na região do Cerrado, no sistema de pecuária extensiva, que favorece a degradação do solo. Entretanto, com o tempo, nem mesmo essas forrageiras conseguem bom desenvolvimento nessas áreas. O objetivo deste trabalho foi analisar a variabilidade dos atributos estudados da planta e do solo; definir as correlações lineares e espaciais entre a produtividade do capim-braquiária com os atributos químicos do solo pesquisado, e pesquisar, dentre os atributos químicos do solo, aquele que melhor se apresente para explicar a variabilidade da produtividade dessa forrageira. A pesquisa foi desenvolvida em uma área manejada com pastagem há 30 anos, na Fazenda de Ensino, Pesquisa e Extensão (FEPE da Faculdade de Engenharia de Ilha Solteira - UNESP, em Selvíria - MS. Foi instalada a malha geoestatística num Latossolo Vermelho aluminoférrico, para a coleta de dados do solo e da planta, contendo 121 pontos amostrais, constituídos de 11 transeções, com 160 m de largura, na direção dos eixos cartesianos. A produção de massa de matéria seca de capim-braquiária foi baixa, apresentando alta variação. Os atributos MSr, N, PB, MO1, MO2, pHa1, pHa2, pHk1 e pHk2 não variaram aleatoriamente e apresentaram variabilidade dos dados entre baixa e alta, e seguiram padrões espaciais bem definidos, com alcances entre 17,7 e 162,9 m. Houve correlação linear significativa a 1% entre a MSr e o N, e entre MSr e a PB. A existência dos semivariogramas cruzados MSr=f(N e MSr=f(PB atestou que essa matéria seca pode ser estimada a partir dos dados do teor de nitrogênio foliar e proteína bruta dessa forrageira.

  2. Is the tribimaximal mixing accidental?

    Abbas, Mohammed; Smirnov, A. Yu.

    2010-01-01

    The tribimaximal (TBM) mixing is not accidental if structures of the corresponding leptonic mass matrices follow immediately from certain (residual or broken) flavor symmetry. We develop a simple formalism which allows one to analyze effects of deviations of the lepton mixing from TBM on the structure of the neutrino mass matrix and on the underlying flavor symmetry. We show that possible deviations from the TBM mixing can lead to strong modifications of the mass matrix and strong violation of the TBM-mass relations. As a result, the mass matrix may have an 'anarchical' structure with random values of elements or it may have some symmetry that differs from the TBM symmetry. Interesting examples include matrices with texture zeros, matrices with certain 'flavor alignment' as well as hierarchical matrices with a two-component structure, where the dominant and subdominant contributions have different symmetries. This opens up new approaches to understanding the lepton mixing.

    To provide a data base for the regulatory guide of light water reactors, behavior of reactor fuels during off-normal and postulated accident conditions such as loss-of-coolant accident (LOCA) and reactivity-initiated accident (RIA) is being studied at the Japan Atomic Energy Research Institute (JAERI). The LOCA program consists of integral thermal shock tests and other separate tests for oxidation rate and mechanical property of fuel claddings. Prior to the tests on irradiated claddings, the tests have been conducted on non-irradiated claddings to examine separate effects of corrosion and hydrogen absorption during reactor operation. The tests on irradiated claddings have recently been started and results have been obtained. As for an RIA study, a series of experiments with high burnup fuel rods is being performed by using pulse irradiation capability of the NSRR. This paper presents recent results obtained from the LOCA and RIA studies at JAERI. (Author)

  6. Effectiveness of cleanup criteria relative to an accidental nuclear release

    1988-01-01

    In the event of an accidental nuclear release, the associated long-term radiological risks would result primarily from ground contamination pathways. Cleanup of the contaminated ground surfaces is a necessary step toward reducing the radiological risk to the general population. Ideally, the radiological risk decreases as the level of cleanup effort increases; however, as the cleanup criterion (i.e., the required contaminant concentration after cleanup) becomes more stringent, the cleanup effort may become prohibitively costly. This study examines several factors that are important in determining the effectiveness of the cleanup criteria for selected radionuclides: (a) annual individual dose commitment (mrem/yr), (b) total population environmental dose commitment (person-rem), and (c) total area (km 2 ) requiring cleanup following an accident. To effectively protect the general population, the benefits of cleanup should be weighed against the potentially large increase in cleanup area (and the associated costs) as the cleanup criterion becomes more stringent. The effectiveness of cleanup will vary, depending largely on site-specific parameters such as population density and agricultural productivity as well as on the amount and type of radionuclide released. Determination of an optimum cleanup criterion should account for all factors, including a comprehensive cost/benefit analysis

    1997-01-01

    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

    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.

Due to its utilization of tumor-avid radiopharmaceuticals labeled with positron-emitting radionuclides, this technique may be especially useful in imaging of women with radiodense or fibrocystic breasts. While the use of these radiotracers affords PEM unique capabilities, it also introduces some limitations. Specifically, acceptance of accidental and Compton-scattered coincidence events can decrease lesion detectability. The authors studied the effect of accidental coincidence events on PEM images produced by the presence of 18F-Fluorodeoxyglucose in the organs of a subject using an anthropomorphic phantom. A delayed-coincidence technique was tested as a method for correcting PEM images for the occurrence of accidental events. Also, a Compton scatter correction algorithm designed specifically for PEM was developed and tested using a compressed breast phantom.

    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.

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

    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

    Five types of magnetic particles without or with aldehyde, amino and carboxyl functional groups, respectively were used to immobilize first or second antibody by three models, i. e. physical adsorption, chemical coupling and immuno-affinity, forming four types of magnetic particle antibodies. The second antibody immobilized on polyacrolein magnetic particles through aldehyde functional groups and the first antibodies immobilized on carboxylic polystyrene magnetic particles through carboxyl functional groups were recommended to apply to RIAs and/or IRMAs. Streptavidin immobilized on commercial magnetic particles through amino functional groups was successfully applied to separating specific PCR product for quantification of human cytomegalovirus. In the paper typical data on reliability of these magnetic particle ligands were reported and simplicity of the magnetic particle separation technique was discussed. The results showed that the technique was a reliable and simple tool for RIA/IRMA and quantitative PCR assay. (author)

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.

    Strangulation is generally considered as homicidal death and in accidental strangulation circumstantial evidence alone can point toward the accidental nature of incidence. In present case, a 71-year-old woman, wearing a saree (garment worn by traditional women in India) working in agricultural field, got entangled in the crop thrasher machine and got strangled. Immediately, she was taken to the nearest hospital, where she survived for 6 to 8 hours and then died. The autopsy reveals cross ribbon-shaped ligature mark on neck and anterior chest along with 1 puncture wound at the right lateral aspect of the neck. A lack of proper precaution and safety measures at agricultural field are other contributing factors. Accidental strangulation by saree is extremely rare, hence, this case is presented for its rarity and pattern of injury.

    Estimation of the radiation released during nuclear accidents or radiological terrorist events is imperative for the prediction of health effects following such an exposure. In addition, in several cases there is a need to identify the prior presence of radioactive materials at buildings or sites (nuclear forensics). To this direction, several materials have been the research object of numerous studies the last decade in an attempt to identify potentially new retrospective/accidental/forensic dosimeters. However, the studies targeting biological materials are limited and their majority is mainly focused on the luminescence behavior of human biological material. Consequently, the use of such materials in retrospective dosimetry presumes the exposure of humans in the radiation field. The present work constitutes the first attempt to seek non-human biological materials, which can be found in nature in abundance or in/on other living organisms. To this end, the present work investigates the basic optically stimulated luminescence behavior of insect wings, which exhibit several advantages compared to other materials. Insects are ubiquitous, have a short life expectancy and exhibit a low decomposition rate after their death. Findings of the present study are encouraging towards the potential use of insects' wings at retrospective/accidental/forensic dosimetry, since they exhibit linear OSL response over a wide dose range and imperceptible loss of signal several days after their irradiation when they are kept in dark. On the other hand, the calculated lower detection limit is not low enough to allow their use as emergency dosimeters when individuals are exposed to non-lethal doses. In addition, wings exhibit strong optical fading when they are exposed to daylight and thus special care should be taken during the sampling procedure in order to use the wings as accidental/forensic dosimeters, by seeking (dead) insects in dark places, such as behind furniture, equipment or in

    Five commercial PAP RIA kits were intercompared by common RIA quality control criteria. All RIAs performed basically well although some differences existed in respect to concentration range, specific and non-specific binding, 50%-intercept, sensitivity and measurements of serum PAP in male and female controls. The latter finding may have been due to differences in antigen purity, antiserum specificity and composition of the assay medium employed. Good correlation was found between PAP determination by RIA and by enzyme assay. First measurements of PAP in patients treated for prostatic carcinoma being performed for orientation purposes are demonstrated. The PAP RIA has been introduced into our routine diagnostic and follow-up of prostatic carcinoma.

    The distributer of the anti-glutamic acid decarboxylase antibody assay kit using radioimmunoassay (RIA) recently announced its discontinuation, and proposed an alternative kit using enzyme-linked immunosorbent assay (ELISA). The aim of the present study was to investigate the diagnostic values of the anti-glutamic acid decarboxylase antibody by RIA and ELISA among type 1 diabetes mellitus patients and control participants. A total of 79 type 1 diabetes mellitus patients and 79 age-matched controls were enrolled and assessed using RIA and ELISA. Sensitivity, specificity, positive predictive values and negative predictive values were calculated for cut-off values (RIA = 1.5 U/mL and ELISA = 5.0 U/mL, respectively). Kappa coefficients were used to test for agreements between the RIA and ELISA methods regarding the diagnosis of type 1 diabetes mellitus. The sensitivity, specificity, positive predictive values, and negative predictive values for diagnosing type 1 diabetes mellitus were 57.0, 97.5, 95.7, and 69.4% by RIA, and 60.8, 100.0, 100.0 and 71.8% by ELISA, respectively. The diagnosis of type 1 diabetes mellitus using the RIA and ELISA methods showed substantial agreement with the kappa values of 0.74 for all participants, and of 0.64 for the acute type; however, there was moderate agreement with the kappa value of 0.56 for the slowly progressive type. The present study suggests that both anti-glutamic acid decarboxylase antibody by RIA and ELISA was useful for diagnosing type 1 diabetes mellitus. However, in the slowly progressive type, the degree of agreement of these two kits was poorer compared with those in all participants or in the acute type. © 2016 The Authors.

    2004-01-01

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

A formação de todas as memórias requer alterações morfológicas nas sinapses: novas sinapses devem ser formadas ou antigas precisam ser fortalecidas. Considera-se que essas alterações reflitam a base celular subjacente das memórias persistentes. Consideráveis avanços têm ocorrido na última década em relação a nossa compreensão sobre as bases moleculares da formação dessas memórias. Um regulador-chave da plasticidade sináptica é uma via de sinalização que inclui a proteína-quinase ativada por mitógenos (MAP. Como essa via é necessária para a memória e o aprendizado normais, não é surpreendente que as mutações nos membros dessa via levem a prejuízos no aprendizado. A neurofibromatose, a síndrome de Coffin-Lowry e a de Rubinstein-Taybi são três exemplos de transtornos de desenvolvimento que apresentam mutações em componentes-chave na via de sinalização da proteína-quinase MAP.Memory is broadly divided into declarative and nondeclarative forms of memory. The hippocampus is required for the formation of declarative memories, while a number of other brain regions including the striatum, amygdala and nucleus accumbens are involved in the formation of nondeclarative memories. The formation of all memories require morphological changes of synapses: new ones must be formed or old ones strengthened. These changes are thought to reflect the underlying cellular basis for persistent memories. Considerable advances have occurred over the last decade in our understanding of the molecular bases of how these memories are formed. A key regulator of synaptic plasticity is a signaling pathway that includes the mitogen

    Van Kirk, Wayne

    2002-11-01

    The acoustical phenomenon observed at an ancient temple in the Great Ball Court at Chichen Itza was described as ''little short of amazing--an ancient whispering gallery'' by Silvanus G. Morley, leader of the Carnegie Institute's archaeological team that excavated and restored these structures in the 1920s. Since then, many others have experienced the extraordinary acoustics at Chichen Itza and other Maya sites. Despite these reports, archaeologists and acousticians have until recently shown little interest in understanding these phenomena. After experiencing Chichen Itza's remarkable acoustics as a tourist in 1994, the author commenced collecting and disseminating information about acoustical phenomena there and at other Mayan sites, hoping to stimulate interest among archaeologists and acousticians. Were these designs accidental or intentional? If intentional, how was the knowledge obtained? How were acoustical features used? This paper highlights the author's collection of anecdotal reports of mysterious Mayan acoustics (http://http://www.ianlawton.com/pa1.htm), recommended reading for scientists and engineers who wish to pursue this fascinating study. Also recounted are some of the reactions of archaeologists-ranging from curious, helpful, and insightful to humorous and appalling--to outsiders' efforts to bring serious scientific attention to the new field of acoustical archaeology.

  5. Work-related accidents and diseases take a heavy toll worldwide Los accidentes y enfermedades laborales causan gran mortalidad en todo el mundo

    Directory of Open Access Journals (Sweden)

    2002-08-01

    Full Text Available Cada año mueren en todo el mundo unos dos millones de personas por enfermedades y accidentes laborales, pero la repercusión total es mucho mayor aun. Según el informe de la Organización Internacional del Trabajo (OIT titulado Informe introductorio: trabajo decente, trabajo seguro, de mayo de 2002, dependiendo del tipo de trabajo, por cada accidente mortal se producen 500 a 2 000 lesiones. Según la OIT, la principal causa de muerte relacionada con el trabajo es el cáncer, responsable de 32% de las muertes, seguido de las enfermedades circulatorias (23%, los accidentes (19% y las enfermedades transmisibles (17%. Las lesiones y las enfermedades laborales suponen un considerable costo económico. Cerca de 4% del producto interno bruto (PIB mundial se pierde en gastos de tratamiento e ingresos no percibidos. El informe de la OIT dice que se podría prevenir cerca de 80% de los accidentes y muertes laborales si todos los países que pertenecen a la organización aplicaran los métodos de prevención de accidentes ya existentes. En los países industrializados, las prioridades deben ser los factores psicosociales ligados a las malas relaciones y gestiones en el lugar de trabajo, las consecuencias mentales y físicas de las tareas repetitivas muy técnicas y la información sobre la manipulación de las nuevas tecnologías y sustancias, entre ellas los productos químicos. En los países que todavía están en fase de industrialización se les debería dar prioridad al mejoramiento de las prácticas sanitarias y de seguridad en las actividades primarias, como la agricultura, la pesca y la explotación maderera; la prevención de los accidentes industriales y la prevención de los accidentes y enfermedades en talleres informales e industrias domésticas.

    1982-01-01

    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 85 Sr or 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 58 Co or 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 58 Co to 66% and 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 58 Co injection decreased the internal radiation dose by approximately 22% or 14%, respectively.

    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) [de

    Although accidents involving the release of radioactive materials and the unplanned exposure of people can occur at any stage of the nuclear fuel cycle, most attention has been focused on reactor accidents. Although no power reactor accidents involving exposure of the public have yet occured, it should be recognized that the probability of such accidental releases cannot be reduced to zero. Since the inventory of radioactive materials in power reactors is very large, it is usual to postulate, for safety assessments, that a release of fission products takes place in spite of all protective measures. This postulated release is of importance for reactor siting and for preparing emergency plans. (HP) [de

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

    International Nuclear Information System (INIS)

    Marchand, M.

    2003-01-01

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

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

  20. Review of RIA and LOCA criteria for WWER fuel

    International Nuclear Information System (INIS)

    Hozer, Z.

    2006-01-01

    The RIA and LOCA fuel safety criteria are under revision in the international community of fuel suppliers, authorities and research organizations. The main criteria will be reviewed in the paper for WWER fuel. Experimental data on the fuel failure behaviour under reactivity-initiated accident (RIA) conditions produced in the last decade in French and Japanese test reactors indicated low failure enthalpy for high burnup fuel compared to fresh fuel. However the high burnup was not the only phenomenon influencing the fuel failure. The oxide scale on the external surface of the fuel rod, hydrogen content of the Zr cladding and the local hydriding seemed also be responsible for the failure at low enthalpy. Furthermore differences have been found between Western design fuel and Russian type WWER fuel. The burnup dependence of fuel failure for WWER fuel was found much less, probably due to the low oxidation during normal operational conditions compared to other PWRs. The recently published Vitanza and KAERI correlations for RIA failure enthalpy have been applied to 23 WWER tests. Experimental data from Russian IGR and BIGR reactors have been used. The calculations have shown that both burnup and cladding oxidation effects must be considered, however the pulse width dependence of failure enthalpy has not been confirmed. During loss of coolant accidents (LOCA) the peak cladding temperature and local oxidation criteria have to be met. The oxidation criterion is under discussion today in many laboratories. The AEKI carried out several experimental series with Zr1%Nb cladding used in WWER reactors. The paper will describe the main results of the tests and present the limit for ductile-brittle transition derived from ring compression test. The behaviour of Zr1%Nb (E110) and Zircaloy-4 claddings under LOCA conditions will be compared as well. (author)

    2003-01-01

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

    The envisioned Rare-Isotope Accelerator (RIA) facility would add substantially to research opportunities for nuclear physics and astrophysics by combining increased intensities with a greatly expanded variety of high-quality rare-isotope beams. A flexible superconducting driver linac would provide 100 kW, 400 MeV/nucleon beams of any stable isotope from hydrogen to uranium onto production targets. Combinations of projectile fragmentation, target fragmentation, fission, and spallation would produce the needed broad assortment of short-lived secondary beams. This paper describes the project's background, purpose, and status, the envisioned facility, and the key subsystem, the driver linac. RIA's scientific purposes are to advance current theoretical models, reveal new manifestations of nuclear behavior, and probe the limits of nuclear existence [3]. Figures 1 and 2 show, respectively, examples of RIA research opportunities and the yields projected for pursuing them. Figure 3 outlines a conceptual approach for delivering the needed beams

    At the 23d WRSM meeting the data base characterizing results of VVER high burnup fuel rods tests under reactivity-initiated accident (RIA) conditions was presented. Comparison of PWR and VVER failure thresholds was given also. Additional analysis of the obtained results was being carried out during 1996. The results of analysis show that the two different failure mechanisms were observed for PWR and VVER fuel rods. Some factors which can be as the possible reasons of these differences are presented. First of them is the state of preirradiated cladding. Published test data for PWR high burnup fuel rods demonstrated that the PWR high burnup fuel rods failed at the RIA test are characterized by very high level of oxidation and hydriding for the claddings. Corresponding researches were performed at Institute of Atomic Reactors (RLAR, Dimitrovgrad, Russia) for large set of VVER high burnup fuel rods. Results of these investigations show that preirradiated commercial Zr-1%Nb claddings practically keep their initial levels of oxidation and H 2 concentration. Consequently the VVER preirradiated cladding must keep the high level of mechanical properties. The second reason leading to differences between failure mechanisms for two types of high burnup fuel rods can be the test conditions. Now such kind of analysis have been performed by two methods

    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

    2003-01-01

    The topical meeting was devoted to RIA fuel acceptance criteria, in particular to the fuel fragmentation enthalpy limit and the PCMI failure enthalpy limit in relation to high burnup fuel. In total 50 participants attended. Research and industry organisations from France, Finland, Germany, Hungary, Japan, the Russian Federation, Sweden, the United Kingdom and the USA including the Swiss regulatory body, HSK, and the Halden reactor project, presented 16 papers in all. The papers covered three main areas: 'best estimate' core calculations for RIA energy deposition in high burnup fuels, the technical background of current and new RIA fuel safety criteria, and ongoing RIA experimental programmes. A number of open issues were identified, whose resolution is expected from ongoing and planned national and international experimental programmes

    Neutronics simulations and activation evaluations are currently in progress as part of the pre-conceptual research and development effort for the Rare Isotope Accelerator (RIA). The RIA project involves generating heavy element ion beams with powers up to 400 kw for use in a fragmentation target line to produce selected ion beams for physics research experiments. Designing a fragmentation beam dump for RIA is one of the most critical challenges for such a facility. Here, we present the results from neutronics and radiation field assessments for various beam dump concepts that can meet requirements for the RIA fragmentation line. Preliminary results from heavy ion transport including radiation damage evaluations for the RIA fragmentation beam dump are also presented. Initial neutronics and activation studies will be incorporated with other target area considerations to identify important challenges and explore possible solutions.

  18. Is the tri-bimaximal mixing accidental?

    CERN Document Server

    Abbas, Mohammed

    2010-01-01

    The Tri-bimaximal (TBM) mixing is not accidental if structures of the corresponding leptonic mass matrices follow immediately from certain (residual or broken) flavor symmetry. We develop a simple formalism which allows one to analyze effects of deviations of the lepton mixing from TBM on structure of the neutrino mass matrix and on underlying flavor symmetry. We show that possible deviations from the TBM mixing can lead to strong modifications of the mass matrix and strong violation of the TBM mass relations. As a result, the mass matrix may have an "anarchical" structure with random values of elements or it may have some symmetry which differs from the TBM symmetry. Interesting examples include matrices with texture zeros, matrices with certain "flavor alignment" as well as hierarchical matrices with a two-component structure, where the dominant and sub-dominant contributions have different symmetries. This opens up new approaches to understand the lepton mixing.

  20. Mycotoxin determination using RIA and ELISA methods

    Fukal, L; Sova, Z

    1985-12-01

    Experience is summed up of various authors with the determination of some mycotoxins (aflatoxin, ochratoxin A, T-2 toxin, rubratoxin, zearalenon, sterigmatocystine) using radioimmunoassay and enzyme immunoassay. For RIA purposes, tritium or sometimes iodine 125 is frequently used for labelling mycotoxins. Mycotoxins do not show immunogenic properties and must thus be conjugated with a high-molecular compound (serum albumin, polylysine) prior to immunozation. Factors are discussed making mycotoxin determination in foods difficult. Specificity of the obtained antisera is total between the individual mycotoxin groups while cross reactions are always recorded within the groups. RIA makes it possible to determine down to 200 pg (labelled with /sup 3/H) or 5 pg (labelled with /sup 125/I) of mycotoxins in a standard solution. In addition to high sensitivity and specificity, immunoassays of mycotoxins minimize the quantities of samples and solvents needed for extraction. Large series of samples can be processed using automatic analyzers. ELISA generally is more advantageous than RIA.

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

    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

  2. Nuclear power: Accidental releases - practical guidance for public health action

    International Nuclear Information System (INIS)

    1987-01-01

    The disaster at Chernobyl, USSR, has caused a major crisis of confidence in nuclear safety, and highlighted the need for comprehensive contingency planning for - and emergency response to - such accidents. This report gives practical guidance on how the authorities should deal with an accident in any type of nuclear installation, whether it involves accidental releases to the air or into water. It is based on principles developed in a previous WHO report published in 1984. It summarizes the range of accidents for which plans need to be made to protect the public, the measures to be taken and the levels of dose at which they should be applied. It indicates how to measure the levels of exposure and what are the most likely routes of exposure. It then outlines the problems faced by public health authorities and medical practitioners, and the administrative arrangements that will have to be made. The example used is of a standard pressurized light water reactor of the type currently used for electricity generation, but many of the features will be common to other nuclear installations as well. This report is addressed to those organizations and individuals responsible for public health in the event of a nuclear accident. It will also be of use to those medical practitioners who are not administratively responsible in an accident, but who may need to be aware of the consequences and of the action to be taken in the aftermath of an accident. Coordination is vital between the public health administration and the organizations with direct responsibilities in the event of an accident, and this report is essential reading for them all. 29 refs, 2 figs, 7 tabs

    First clinical experience with a estradiol RIA kit developed in the Central Institute for Isotope- and Radiation Research is reported. The kit was used for the daily control of estradiol level in patients, which were treated within the program for in vitro fertilization and embryo transfer. The time of incubation could be shortened by means of a double antibody technique and by use of a precipitation mixture to 2 h. The intraassay variation is 9.2%, the interassay variation is 15.1%, the recovery rate is 94%. The sensitivity of the test (B 0 -3SD) is about 120 pmol/l. The estradiol RIA kit satisfies clinical requirements. (author)

    2018-01-01

    Accidental cut-throat injuries are extremely rare and usually involve a sharp-edged weapon. In this paper, two cases of a cut-throat wound to two auto-rickshaw drivers are presented where the broken windshield of the auto-rickshaws was responsible for the wounds. In both the cases, fatal incised wounds were present over the neck, cutting the soft tissue along with the major vessels. The death occurred due to exsanguination caused by neck-vessel injury in one case and trachea along with neck-vessel injury in the second case. Although the wounds on the neck initially suggested homicide, they were found to have occurred accidentally as a result of a road traffic accident involving a head-on collision of auto rickshaws. The injuries were inflicted by the shattered glass of the windshield.

    An improvement in a tritium control system based on a catalytic oxidation reactor is provided wherein accidental releases of tritium into room air are controlled by flooding the catalytic oxidation reactor with hydrogen when the tritium concentration in the room air exceeds a specified limit. The sudden flooding with hydrogen heats the catalyst to a high temperature within seconds, thereby greatly increasing the catalytic oxidation rate of tritium to tritiated water vapor. Thus, the catalyst is heated only when needed. In addition to the heating effect, the hydrogen flow also swamps the tritium and further reduces the tritium release

    Certain assumptions are given for the amount of fission products released from a research reactor after the occurrence of an accident. The size and location of radioactive cloud are assumed, and the corresponding external and internal exposures of workers are computed. A method is suggested for assessment of accidental external radiation dose based on experimental studies performed on the changes of quenching effect of plasma or sera as a.result of whole- body gamma-radiation ranging from 25-200 rems. For assessment of accidentally internally incorporated gamma emitters we suggest the standard chair whole-body counter technique which was found to detect reliably 1/100 of the maximum permissible body burden within eight minutes. It was also suggested that a separation method based on the use of absorption phenomena observed for Sephadex (gel resin) can be applied for quick determination of gross alpha activity in urine. For management of accidentally exposed workers to radiation doses of a lethal or sublethal nature, bone-marrow transplantation therapy and blood component therapy in sterile rooms is discussed in the light of experience gained from treatment of leukaemia with intensive chemotherapy.

  9. Twentieth century overview of heavy metals in the Galician Rias (NW Iberian Peninsula)

    Prego, R.; Cobelo-Garcia, A.

    2003-01-01

    All information published on metals in this region up to the year 2000 is reviewed from a biogeochemical viewpoint. - The 18 Galician Rias, comprising 25% of the Iberian Peninsula coastline, form a unique system within the European continental Atlantic coast and provide a useful reference area for studies of metals. These rias are sensitive to anthropogenic influence due to the socioeconomic importance generated in these areas by industry, aquaculture, port activities, fishing, tourism and, accordingly, several islands lying within close proximity to the rias have recently been declared natural parks. Aquaculture in the Galician Rias is a growth industry and in 2000 the rias supported 3386 mussel rafts producing 2.5x10 8 kg year -1 , i.e. 40% of European Union total seafood production. The Galician Rias are partially stratified estuaries with positive residual circulation with fresh (runoff lower than 100 m 3 s -1 ) and salt water mixing inside the basins. This behaviour has direct consequences on metal fluxes whereby the rias behave as a barrier and accumulate metals in the sediments. Metals tend to deposit close to point sources and remobilization occurs inside the ria, leading to a seaward decrease in metal concentration. With the exception of the Ulla (Arosa Ria) and Eume (Ares-Betanzos Ria) head rivers and the Lagares river (Vigo Ria) the available data suggest that riverine freshwater inputs are not the main source of contamination. Metal studies reported in the literature mainly relate to Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn, and to a lesser extent Hg and Sn. Studies of other harmful metals such as Ag, Se and As are notably lacking. In addition, the studies have been localized and mainly restricted to the surface sediment. Data of heavy metals in the dissolved phase, suspended particulate matter and biota is scarce in the mainstream literature and should be considered in the future research. From the entire Galician coast, data from seven rias of socio

    2004-01-01

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

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

    1978-12-01

    The primary objectives of Test RIA 1-2 were to (a) characterize the response of preirradiated fuel rods during an RIA event conducted at boiling water reactor (BWR) hot-startup conditions for an axial peak pellet surface energy of 200 cal/g UO 2 , and (b) evaluate the effect of internal rod pressure on preirradiated fuel rod response during an RIA event. The test consisted of four, individually shrouded, pressurized water reactor-type fuel rods previously irradiated to burnups of about 4800 MWd/t. In addition to the power calibration and preconditioning, the fuel rods were subjected to a single power burst that deposited a total pellet surface energy of approximately 200 cal/gm UO 2 at the axial peak power location (estimated using the core power chambers to relate steady state and transient powers). The test data indicate that the two irradiated fuel rods prepressurized to 2.41 MPa did not fail. FRAP-T4 calculations had predicted that prompt cladding rupture would occur for pellet surface energy depositions of 206 cal/g or greater. Although the two fuel rods prepressurized to 2.41 MPa did not fail, the data indicate that at least one of the two fuel rods prepressurized to 0.1 MPa did fail. Based on the core power chamber data, this rod failure indicates a threshold for the preirradiated fuel rods near or below 200 cal/g UO 2 total pellet surface energy at the axial flux peak

This study also describes a comparative analysis of the various forms of regulation and the associated regulatory research, with the ultimate goal of better defi ning the concept and to validate the need to have research groups within a country’s regulatory bodies. Based on this work, we conclude that regulatory research is a key factor in the success of any regulatory body’s activities. Such research helps to avoid the creation of absurd or impractical regulatory barriers to a country’s technological development, or worse, to permit “orphans,” that is, technologies that are outside regulatory control, as is currently the case. Indeed, for a country to have a robust technological infrastructure, especially if it is still a developing country, strong and competent regulatory control is essential. However, this must be balanced by an atmosphere that fosters continuous and consistent technological innovation, and such development must also be self-sustainable from economic, social, and environmental viewpoints. ------------------------------------------------ Apresenta-se neste trabalho o conceito, a importância e a abrangência da pesquisa regulatória no âmbito da regulação e da regulamentação, com foco particular na regulamentação relacionada à metrologia legal.

    Full Text Available Understading the hydrodynamic behavior and suspended particulated matter (SPM transport are of great importance in port regions such as Vitória Harbor, which is located at Vitória Bay, Vitória – ES, Brazil. Vitória Bay is an estuary that has not been systematically assessed through a temporal analysis in order to identify its hydrodynamics characteristics and SPM exchange. This study aims to investigate salt and suspended particulate matter flux at the estuarine mouth of Vitória Bay by understanding the temporal variation of salinity, temperature and tidal currents within the water column and at the channel crosssection. Results showed that the estuarine mouth tended to present partial stratification periods during neap tides and little stratification in spring tides. The circulation pattern was mainly influenced by the tide, with little influence from river discharge. With regard to the SPM, the mouth of the estuary tended to show low concentrations, with the highest values occurring during the dry season. A close relationship between momentary discharge, SPM and salt fluxes was observed. Despite all the data was collected at the mouth of the estuary, the system showed an importation trend of salt in all cycles and SPM importation for three of the four studied tidal cycles. Thus, Vitoria Bay is not exporting SPM to the adjacent inner shelf.

    Sodium hypochlorite (NaClO) has been widely used in clinical practice as one of the most efficient root canal irrigants. Its properties include broad-spectrum antimicrobial activity and ability to dissolve necrotic tissues. However, when used improperly, NaClO can cause a series of adverse reactions, such as mucosal inflammation, irritation, or injury. This paper presents a case of accidental injection of NaClO in inferior alveolar nerve block anesthesia.

    Full Text Available Botulinum toxin type A (BT-A has been described as an important strategy to various types of pain such as cervical dystonia, myofascial pain syndrome and headache. Although BT-A efficacy has not been proven in tension type headache, its use in migraine continues controversial. In this open trial, we evaluated the efficacy of BT-A in refractory migraine. BT-A was injected in patients diagnosed with migraine who had previously used three classes of prophylactic drugs by at least one year with no response. The most important improvement was observed within 30 days, but pain intensity and frequency of headache had been decreased until the end of three months of follow up. Side effects of BT-A were mild and self limited. We conclude that BT-A seems to be a safe and effective treatment to refractory migraine patients.Toxina botulínica tipo A (TB-A tem sido descrita como importante estratégia para diversos tipos de dor como cefaléia e dores relacionadas a distonia cervical ou síndrome miofascial. Embora a eficácia da TB-A não tenha sido demonstrada na cefaléia do tipo tensional, seu uso na enxaqueca continua controverso. Nesse estudo avaliamos a eficácia da TB-A na enxaqueca refratária. TB-A foi injetada em pacientes com enxaqueca que fizeram tratamento prévio com no mínimo três classes de medicamentos profiláticos, sem resultados satisfatórios. A melhora mais significativa dos pacientes foi observada após 30 dias de aplicação de TB-A, enquanto intensidade da dor e freqüência de cefaléia continuaram reduzidas até o final de três meses de seguimento. Os efeitos colaterais observados após a aplicação de TB-A foram moderados e auto-limitados. Os nossos dados mostram que TB-A parece ser um tratamento seguro e eficaz para pacientes com enxaqueca refratária.

    Full Text Available São reunidos os dados relativos a 23 casos de obstrução de artérias crânio-encefálicas: carótida primitiva em 2 casos; carótida interna em 16 casos; artéria cerebral em 2; cerebral média em 3. São analisados a incidência da obstrução arterial em relação à idade e ao sexo, sua sintomatologia e os métodos de diagnóstico. Foi observada nítida predileção para o sexo masculino. As idades extremas dos pacientes foram de 10 meses e de 56 anos, variando os restantes entre 20 e 50 anos. Quanto às manifestações clínicas destaca-se a hemiplegia, que ocorreu em 21 dos pacientes. No tocante ao diagnóstico angiográfico, os autores são de opinião que, para afastar a possibilidade de oclusão transitória devida a espasmo, é importante que o mesmo aspecto seja verificado em exames sucessivos, principalmente quando o segmento visível da artéria ocluída não apresentar deformação característica. Como contraprova foi feita, em 12 casos, a angiografia controlateral; em nenhum destes casos houve qualquer acidente atribuível ao exame. A angiografia controlateral, além de constituir contraprova da oclusão vascular, permite o estudo da circulação de suplência.

    Full Text Available Este trabalho objetivou selecionar bactérias diazotróficas isoladas de bananeira (Musa spp. e avaliar sua influência no crescimento de mudas micropropagadas. Bactérias do tipo Herbaspirillum e relacionadas a Burkholderia cepacia foram inoculadas em plântulas de banana cv. Prata Anã e cv. Caipira. As bananeiras cv. Prata Anã, cultivadas in vitro com substrato pobre em N, apresentaram maior crescimento na presença de bactérias do tipo Herbaspirillum, ao passo que as bananeiras cv. Caipira cresceram melhor com o inóculo contendo bactérias do gênero Burkholderia. Em casa de vegetação, as bananeiras cv. Caipira crescidas em sacolas de plástico contendo areia e vermiculita (1:2, suplementada com a solução de Hoagland contendo 5 mg L-1 de N, apresentaram maior crescimento quando da inoculação simultânea dos dois gêneros de bactérias, em comparação à inoculação individual. A inoculação simultânea proporcionou um crescimento nas bananeiras equivalente ao observado nas plantas-controles adubadas com 50 mg L-1 de N no substrato, porém o teor e o acúmulo de N na parte aérea das bananeiras foram menores. A contribuição de bactérias diazotróficas no crescimento de bananeiras é demonstrada pela primeira vez.

    Full Text Available  Recentemente, a pesquisa em ciência social tem dado mais atenção às intrincadas relações entre biografia e história. Na pesquisa educacional, esse foco resultou numa explosão do interesse na narrativa pessoal como uma articulação da experiência individual e coletiva com os mundos social, político e cultural da educação. Esse interesse na narrativa pessoal deu, por conseqüência, proeminência ao trabalho em história oral. O crescimento da atração intuitiva das narrativas pessoais, no entanto, ganhou uma complacência metodológica. O que significa coletar e analisar narrativas pessoais? Como os narradores verbalizam suas narrativas e narram sua voz? Que papel exerce o jogo das entrevistas no desdobramento dessas narrativas? O que significam essas questões no contexto das histórias orais, que são narrativas em que a dinâmica entrevistador-narrador também é mediatizada pela natureza da memória?

    Full Text Available Objetivos: avaliar as taxas de gravidez após realização de reversão laparoscópica de obstrução tubária por laqueadura prévia. Métodos: entre dezembro de 1998 e dezembro de 2001, realizamos estudo prospectivo no qual foram incluídas 26 pacientes previamente submetidas a esterilização tubária. As pacientes tinham idades entre 28 e 37 anos e a reanastomose foi efetuada por via laparoscópica. O período de seguimento variou entre 150 e 425 dias e as taxas de permeabilidade tubária (estudada por meio da histerossalpingografia e as taxas de gestação foram avaliadas. Resultados: a reversão laparoscópica pôde ser realizada em 23 pacientes, sendo bilateral em 21. Duas pacientes apresentavam uma tuba extremamente danificada e três haviam sido submetidas a fimbriectomia bilateral. O tempo cirúrgico variou de 95 a 155 minutos e a alta hospitalar ocorreu na manhã seguinte em todos os casos. Constatou-se permeabilidade tubária em 15 pacientes (15/23 e a taxa de gestação foi 56,5% (13/23, sem gestações ectópicas. O intervalo entre a interrupção do uso do condom e a gravidez foi de até quatro meses em nove pacientes e de até 10 meses em quatro pacientes. Conclusão: em casos selecionados, a reversão tubária videolaparoscópica pode ser oferecida à pacientes laqueadas que desejam novas gestações. A seleção adequada das pacientes, assim como técnica cirúrgica meticulosa, são os fatores-chave para atingir taxas de gestação satisfatórias.

    Few studies have been published to demonstrate tolerability and efficacy of almotriptan in adolescents and children with migraine, particularly in the first years of life, though preliminary results are favorable. We report the case of an 18-month-old infant with elevation of serum levels of creatin-kinase after the accidental ingestion of almotriptan. A previously healthy 18-month-old girl (weight: 13 kg) was admitted to our Department four hours after the accidental ingestion of 6.25 mg of almotriptan (0.48 mg/kg), without any specific symptom. The performed investigations showed high serum levels of creatin-kinase (CK) (527 IU/L; normal values: 24-170 IU/L). Transaminase, creatinine, aldolase, myoglobin and troponin T serum levels were normal. The electrocardiogram proved negative. Initial management consisted of parenteral rehydration with saline solution. CK levels lowered significantly at 12 hours (455 IU/L) and at 65 hours (188 IU/L) after the ingestion. No symptoms were observed before discharge and on follow-up.

    2003-03-01

    All information published on metals in this region up to the year 2000 is reviewed from a biogeochemical viewpoint. - The 18 Galician Rias, comprising 25% of the Iberian Peninsula coastline, form a unique system within the European continental Atlantic coast and provide a useful reference area for studies of metals. These rias are sensitive to anthropogenic influence due to the socioeconomic importance generated in these areas by industry, aquaculture, port activities, fishing, tourism and, accordingly, several islands lying within close proximity to the rias have recently been declared natural parks. Aquaculture in the Galician Rias is a growth industry and in 2000 the rias supported 3386 mussel rafts producing 2.5x10{sup 8} kg year{sup -1}, i.e. 40% of European Union total seafood production. The Galician Rias are partially stratified estuaries with positive residual circulation with fresh (runoff lower than 100 m{sup 3} s{sup -1}) and salt water mixing inside the basins. This behaviour has direct consequences on metal fluxes whereby the rias behave as a barrier and accumulate metals in the sediments. Metals tend to deposit close to point sources and remobilization occurs inside the ria, leading to a seaward decrease in metal concentration. With the exception of the Ulla (Arosa Ria) and Eume (Ares-Betanzos Ria) head rivers and the Lagares river (Vigo Ria) the available data suggest that riverine freshwater inputs are not the main source of contamination. Metal studies reported in the literature mainly relate to Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn, and to a lesser extent Hg and Sn. Studies of other harmful metals such as Ag, Se and As are notably lacking. In addition, the studies have been localized and mainly restricted to the surface sediment. Data of heavy metals in the dissolved phase, suspended particulate matter and biota is scarce in the mainstream literature and should be considered in the future research. From the entire Galician coast, data from seven

    Full Text Available The aim of this study was to analyze studies evaluating the association between the level of physical activity and the occurrence of accidental falls in the elderly. A systematic literature review of the LILACS and MEDLINE databases was conducted. As inclusion criteria, complete scientific articles investigating subjects older than 60 years, published in Portuguese, English or Spanish, were selected. Twenty-nine articles were retrieved, five from LILACS (1982 to 2007, two from MEDLINE (1966 to 1996, and 22 from MEDLINE (from 1997 to 2007. Ten (35% articles were selected based on the inclusion criteria and 19 (65% were excluded. A cross-sectional design was the most frequent type of study (60%. The studies identified suggest an association between the level of physical activity and factors related to the occurrence of falls such as functional disability, quality of life and independence to perform daily activities. Falls were found to restrict physical activity in some studies. In view of the heterogeneity of the studies in terms of methods and assessments, it was not possible to determine whether a better level of physical activity is able to decrease the incidence of falls in the elderly.

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

    International Nuclear Information System (INIS)

    Simmonds, J.R.

    1985-02-01

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

As alterações periodontais, identificadas por exame clínico, foram tabuladas considerando raça, dieta, faixa etária e sexo. Os índices gengival e de placa foram aplicados a todos os animais e análise radiográfica foi realizada quando necessária. O levantamento epidemiológico revelou elevada freqüência de alterações relacionadas à presença de placa bacteriana e de alterações gengivais. Observou-se também agravamento das alterações com o avançar da idade, evidenciado radiograficamente. Os animais alimentados somente com ração apresentaram menor freqüência de alterações relacionadas aos índices gengival e de placa, em relação àqueles alimentados com dieta caseira. Não se observou diferença entre sexos quanto às alterações dentárias.The type and frequency of dental diseases and disorders in 215 dogs were studied. Periodontal disorders were identified through clinical investigation, microbiological and histopathological examination. Radiographs were taken in case of severe dental and periodontal disorders. Disorders were classified according to breed, diet, age and sex. Gingival and plaque indexes were estimated in all animals. The study showed a high frequency of disorders like dental plaque and gingival lesions. Disorders were more severe in older animals. Animals fed only with commercial rations showed a lower frequency of disorders related to gingival and plaque than animals fed with human waste food. No differences between male and female frequency of disorders were observed. The radiographic evaluation was an important and useful method for the diagnosis of periodontal disorders.

    A 37-year-old man with known intravenous drug abuse presented in the surgical ambulatory care unit with acute leg ischemia after accidental intra-arterial injection of dissolved flunitrazepam tablets into the right femoral artery. A combination of anticoagulation, vasodilatation, and local selective and superselective thrombolysis with urokinase was performed to salvage the leg. As a result of the severe ischemia-induced pain, the patient had to be monitored over the complete therapy period on the intensive care unit with permanent administration of intravenous fluid and analgetics. We describe the presenting symptoms and the interventional technique, and we discuss the recent literature regarding the management of accidental intra-arterial injection of dissolved flunitrazepam tablets.

    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. © 2015 Wiley Periodicals, Inc.

    This white paper first states a set of fourteen recommendations regarding crisis management planning, post-accidental management planning, waste management, and the roles of CLIs (local information commissions) in crisis and post-accidental management planning. After an introduction which proposes a presentation of roles CLIs could play in the different stage of this planning (preparation, emergency or crisis, post-accidental), and a discussion of concerned territories, this white paper discusses territory zoning (zoning in situation of emergency, in post-accidental situation) and roles of territories and CLIs. The next part addresses the issue of decontamination: pollution and contamination management (territory decontamination, issue of water resources, waste management) and discusses the roles of territories and CLIs on these issues. The third part addresses the issue of support and protection of population regarding different aspects: census, relocation, continuity of public services, continuity of economic activities, food restrictions, medical follow-up and epidemiology, and compensations. The roles of territories and CLIs on these issues are discussed. The fourth part addresses the issues of information and communication in a crisis or post-accidental situation. The fifth part discusses tools and means needed by the CLIs to cope with these situations. Short contributions from different institutions (ASN, IRSN) and members of the ANCCLI are finally proposed

    Full Text Available L’educació secundària obligatòria sembla que estigui permanentment en crisi: situacions conflictives entre els diferents agents, fracàs escolar, bullying o reiterades modificacions curriculars són alguns dels múltiples exemples que envaeixen els medis educatius i el debat social i accentuen les crítiques i les experiències negatives que es donen en aquesta etapa educativa. Certament, la secundària obligatòria té com a repte fonamental la comprensivitat, que comporta l’atenció a la diversitat de tots els adolescents en una etapa vital complicada; aquest repte educatiu i social, sens dubte, ha de tenir ombres, però també té llums en forma d’experiències reeixides que convergeixen en un millor i major aprenentatge de l’alumnat. La recerca que es presenta en aquest article es proposa fer emergir i difondre les característiques que reuneixen les pràctiques exitoses que es donen a les aules de la secundària obligatòria. La metodologia usada per assolir aquesta finalitat essencial ha estat el recull i l’anàlisi de relats de persones de diferents trams d’edat sobre les seves millors experiències en la secundària obligatòria com a alumnes.Els diversos objectius que es pretenen amb el recull i l'estructuració d’aquestes veus es poden sintetitzar en dos: identificar les característiques essencials o components de les «bones pràctiques» i contribuir a la reflexió i el debat en la formació inicial i permanent del professorat. A partir de les aportacions recollides es pot concloure que: - A l’ESO, en el nostre context, es registren nombroses experiències reeixides per a l’aprenent.

    It has been assessed that the capital cost for future nuclear power plants needs to be reduced on the order of 35% to 40% for Advanced Light Water Reactors such as KNGR and System 80+. Such reduction in the capital cost will require a fundamental re-evaluation of the industry standards and regulatory basis under which nuclear plants are designed and licensed. The objective of this study is to develop the risk-informed assessment (RIA) design methodology for future nuclear power plants. In order to meet this objective, the design simplification method is developed and RIA design methodology exercised for conceptual system. For the methodology verification, simplified conceptual ECCS and feedwater system are developed, then LOCA sensitivity analyses and agressive secondary cooldown analyses for these systems are performed. In addition, the probability safety assessment (PSA) model for LOCA is developed and the validation of RIA design methodology is demonstrated

One of the most efficient means at the disposal of any firm, to improve the morale of the individual employees, and to establish a spirit of cooperation between the individual and the firm, is to set up a program of accident benefit. It will avoid direct and indirect losses due to working accidents, as analyzed in a previous article, and it will make it possible to improve total performance of each worker, since he will work in a more favorable environment, free from worry about potential danger to his person. It is almost impossible to describe in detail all those items that should be taken into account in a safety program. None the less, and as an indication of their diversity, some sources of danger are mentioned in this chapter, which are closely connected with human safety, such as public curiosity, travelling from one place to another, cleanliness and order.Todas las personas prefieren desempeñar sus tareas en aquellas organizaciones que tienen hacia ellos las consideraciones correspondientes a un ser humano. Uno de los medios más eficaces a disposición de cualquier empresa para elevar la moral del individuo y para crear un lazo de cooperación común entre el individuo y la empresa, es la de llevar a cabo un programa de prevención de accidentes, programa que redundará en el doble fruto: evitar las pérdidas directas e indirectas causadas por los accidentes de trabajo que se detallaron en un trabajo anterior, y conseguir aumentar el rendimiento del operario al hacerle un ambiente más grato por la preocupación que se demuestra hacia su persona. Es casi imposible detallar todos aquellos puntos que se deben tener en cuenta en un programa de seguridad; sin embargo, y como exponente de su diversidad, se señalan en este capítulo algunas causas, que, sin estar ligadas directamente con el trabajo individual, no obstante se encuentran

    Full Text Available Paracetamol is one of the most commonly used analgesics and antipyretics available without limits as preparations of the OTC group (over the counter drugs. Overdose and poisoning with this drug always brings about the risk of acute hepatic failure. The objective of the study was a retrospective evaluation of patients hospitalized in the Paediatric Clinic during the period 2004–2012 due to poisoning with paracetamol.The analysis covered 44 patients hospitalized in the Paediatric Clinic during 2004–2012 due to poisoning with paracetamol. Patients were divided into three groups: intentional poisonings, accidental poisonings, and drug overdose.During the period of the study, 44 patients aged 2.1–17.1, poisoned with paracetamol, were hospitalized. Among these patients there were 30 (68.2% cases of intentional poisonings, 10 (22.7% of accidental poisonings, and only 4 patients (9.1% were children hospitalized after a paracetamol overdose. The majority of patients in all groups were females (93.3%.Paracetamol intoxication may occur after exceeding a single allowable dose, in the case of intentional poisoning, more rarely after exceeding the daily dose, in the case of intense pain complaints, or in the treatment of persistent fever.Based on the analysis performed, an increase was observed in the frequency of poisoning with paracetamol, especially intentional poisoning. Unlimited access to paracetamol as an OTC drug should be reconsidered.

    Clustering may simply represent a convenient method for organizing a large data set so that it can easily be understood and information can efficiently be retrieved. However, identifying cluster in high dimensionality data sets is a difficult task because of the curse of dimensionality. Another challenge in clustering is some traditional functions cannot capture the pattern dissimilarity among objects. In this article, we used an alternative dissimilarity measurement called Robust Influence Angle (RIA) in the partitioning method. RIA is developed using eigenstructure of the covariance matrix and robust principal component score. We notice that, it can obtain cluster easily and hence avoid the curse of dimensionality. It is also manage to cluster large data sets with mixed numeric and categorical value.

    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

    Brake cleaner liquid is commonly used for cleaning of engines and motor parts. The commercially available products usually contain mainly volatile organic compounds. As a consequence brake cleaner evaporates fast and almost completely from the cleaned surface. This case report presents a fatal accidental inhalation of brake cleaner liquid aerosols due to the attempted cleaning of a boat engine. A 16year old boy was found lifeless in the engine compartment of a boat engine. In close proximity to the body, the police found cleanings wipes soaked with brake cleaner as well as a pump spray bottle filled with brake cleaner. Essentially the autopsy revealed a cerebral oedema with encephalomalacia, no coagulated blood as well as increased blood and tissue fluid content of the lung. Toxicological analysis revealed brake cleaner fluid in the lung, gastric content and heart blood. Copyright © 2018 Elsevier B.V. All rights reserved.

    The Coat-A-Count solid phase 125 I Fentanyl Radioimmunoassay was evaluated with respect to linearity and precision using equine urine fortified with fentanyl and then compared with a gas chromatographic/mass spectrometric method for quantification of fentanyl in urine. The RIA assay was found to be linear over the urine fentanyl concentration range of 0.25 to 7.5 ng/mL and precise with coefficients of variation (CV) ranging from 9.6 to 19.3%. The RIA calibrators, ranging in fentanyl concentrations from 0.25 to 7.5 ng/mL, and controls, at mean fentanyl concentrations of 0.46 and 1.32 ng/mL, were compared by both the RIA and GC/MS methods. The cross-reactivity with the 125 I RIA test was determined for the fentanyl metabolites, norfentanyl and hydroxyfentanyl, and found to be 5% and 35%, respectively. The illicit fentanyl analogs were found to show significant cross-reactivity, ranging from 20 to 100%. The 125 I RIA was compared to GC/MS quantifications of fentanyl in 35 positive and 20 negative case urine specimens

    Full Text Available A pesquisa teve por objetivos analisar as representações sociais sobre História por alunos da Educação de Jovens e Adultos e compreender como esses estudantes se percebem inseridos na História. Participaram da pesquisa sessenta e dois alunos do 3º ano do Ensino Médio, modalidade EJA, de escola pública do Estado de São Paulo. Os dados foram coletados pela pesquisadora, por meio de questionário semiestruturado, e foram analisados pela técnica de análise de conteúdo. Os resultados indicam que os participantes representam história como disciplina escolar construída por grandes heróis, ignorando sua participação efetiva na mesma enquanto sujeitos históricos. Esses jovens e adultos apresentam uma concepção que se aproxima da perspectiva tradicional da História, isto é, de uma história essencialmente política e voltada para os grandes acontecimentos. Os resultados sugerem, ainda, que as representações sociais sobre História estariam relacionadas a uma permanência de práticas pouco problematizadoras, presentes na escola dos pesquisados.

Entende-se por socioeconomia solidária, alternativas que visem minimizar problemas relacionados ao desemprego crescente, sendo também uma fonte de geração de renda para parte da população que não é atendida pelo modo capitalista de produção. A prática de socioeconomia solidária constitui-se como um fenômeno antigo, tendo origem com a Revolução Industrial. Porém, observa-se um incentivo maior a esta outra economia a partir das últimas décadas do século XX, principalmente no Brasil, destacando-se o processo de expansão da socioeconomia solidária no país, bem como no estado de Minas Gerais.

    Full Text Available Recently, the veterinarians are dealing with a number of cases that require forensic expertise. Such a circumstance could be the accidental electrocution in animals, one of the causes of unnatural death. There is a scarcity with reference to the pathological findings in veterinary forensic medicine. In this paper, we present the main lesions that occurred in a horse with accidental electrocution that was presented for complete necropsy survey. A horse corpse was sent to the Pathology Department (Faculty of Veterinary Medicine, Cluj-Napoca, Romania for a full medical survey. Preliminary results and external examination: the body was in rigor mortis; from the nasal cavities drained out reddish foam and in the mouth was observed the presence of ingested feed (straw that was not chewed, suggesting a quick death. The findings detected after internal examination of the carcass were poor blood coagulability, haemorrhagic diathesis throughout the body, with haemorrhages of various sizes in different body regions (e.g., muscles of the withers, in the gluteal muscle, the mucosa of epiglottis, larynx, trachea, in the interstitium of the lung, and ecchymosis in the left kidney. Some other lesions detected were infarcts and haemorrhages in the fundic region of the stomach’s mucosa. In electrocution, haemorrhages are most often located in the respiratory tract, aspect observed in our case too. However, the diagnosis of electrocution has to corroborate the necropsy findings (which are not specific, with some other data such as the fulminant death and inspection of power source.

    Full Text Available The objective of this study was to review mortality from external causes (accidental injury in children and adolescents in systematically selected journals. This was a systematic review of the literature on mortality from accidental injury in children and adolescents. We searched the Pubrvled, Latin-American and Caribbean Health Sciences and Excerpta Medica databases for articles published between July of 2001 and June of 2011. National data from official agencies, retrieved by manual searches, were also reviewed. We reviewed 15 journal articles, the 2011 edition of a National Safety Council publication and 2010 statistical data from the Brazilian National Ministry of Health Mortality Database. Most published data were related to high-income countries. Mortality from accidental injury was highest among children less than 1 year of age. Accidental threats to breathing (non-drowning threats constituted the leading cause of death among this age group in the published articles. Across the pediatric age group in the surveyed studies, traffic accidents were the leading cause of death, followed by accidental drowning and submersion. Traffic accidents constitute the leading external cause of accidental death among children in the countries understudy. However, infants were vulnerable to external causes, particularly to accidental non-drowning threats to breathing, and this age group had the highest mortality rates for external causes. Actions to reduce such events are suggested. Further studies investigating the occurrence of accidental deaths in low-income countries are needed to improve the understanding of these preventable events.

    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

    2012-02-10

    The investigation of uncertain fatalities requires accurate determination of the cause of death, with assessment of all factors that may have contributed to it. Gasoline is a complex and highly variable mixture of aliphatic and aromatic hydrocarbons that can lead to cardiac arrhythmias due to sensitization of the myocardium to catecholamines or acts as a simple asphyxiant if the vapors displace sufficient oxygen from the breathing atmosphere. This work describes a sudden occupational fatality involving gasoline. The importance of this petroleum distillate detection and its quantitative toxicological significance is discussed using a validated analytical method. A 51 year-old Caucasian healthy man without significant medical history was supervising the repairs of the telephone lines in a manhole near to a gas station. He died suddenly after inhaling gasoline vapors from an accidental leak. Extensive blistering and peeling of skin were observed on the skin of the face, neck, anterior chest, upper and lower extremities, and back. The internal examination showed a strong odor of gasoline, specially detected in the respiratory tract. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography with flame ionization detector and confirmation was performed using gas chromatography-mass spectrometry. Disposition of gasoline in different tissues was as follows: heart blood, 35.7 mg/L; urine, not detected; vitreous humor, 1.9 mg/L; liver, 194.7 mg/kg; lung, 147.6 mg/kg; and gastric content, 116,6 mg/L (2.7 mg total). Based upon the toxicological data along with the autopsy findings, the cause of death was determined to be gasoline poisoning and the manner of death was accidental. We would like to alert on the importance of testing for gasoline, and in general for volatile hydrocarbons, in work-related sudden deaths involving inhalation of hydrocarbon vapors and/or exhaust fumes.

    Torres, M.M.C.

    1996-01-01

    Seven different methods were used to estimate the dose rate to a female worker who was accidentally exposed in the neutron PHOENIX beamline at the IPNS. Theoretical and measured entrance dose rates ranged from 550 mrem/min to 2,850 mrem/min. Theoretical estimates were based on a Monte Carlo simulation of a spectrum provided by IPNS (Crawford Spectrum). Dose measurements were made with TLDs on phantoms and with ionization chambers in a water phantom. Estimates of the whole body total effective dose equivalent (TEDE) rate ranged from 5.2 mrem/min to 840 mrem/min. Assumed and measured quality factors ranged from 2.6 to 11.8. Cytogenic analyses of blood samples detected no positive exposure. The recommended TEDE rate was 158 mrem/min. The TEDE was 750 mrem

    Full Text Available El objetivo de este artículo es identificar el comportamiento de las muertes por accidentes de motocicleta y las variables relacionadas con la teoría de la reproducción social de Samaja, para el período 2000-2005 en el estado de Pernambuco, Brasil. Se realizó un estudio ecológico con abordaje caso-control. La unidad de análisis fue el municipio. Los casos fueron definidos considerando el 20% de los municipios con los mayores coeficientes bayesianos empíricos locales de mortalidad por accidentes de motocicleta y los controles, como el 40% de los municipios con menores coeficientes de mortalidad por accidentes de motocicleta. Los municipios con mayor probabilidad de altos coeficientes de mortalidad por accidentes de motocicleta mostraron factores de crecimiento poblacional altos, así como de crecimiento de la flota de vehículos, bajas densidades demográficas, bajo PBI per cápita, y más de 20 motocicletas por mil habitantes. Se concluye que las variables relacionadas a las macropolíticas mostraron una mayor fuerza para explicar las probabilidades de defunciones por accidentes de motocicleta.

  20. Simulation of pulsed accidental energy release in a reactor core

    1995-01-01

    At the present time the strength of the load-bearing members of VVER and fast reactors during a hypothetical accident is ordinarily investigated in model experiments [1]. A power burst during an accident is simulated by a nonnuclear exothermal reaction in water, which simulates the coolant and fills the model. The problem is to make the correct choice of the simulator of the accidental energy burst as an effective (i.e., sufficiently high working capacity) source of dangerous loads, corresponding to the conditions of an accident. What factors and parameters determine the energy release? The answers to these questions are contradictory

Então, busca-se com este artigo analisar a presença da temática da pobreza nos trabalhos apresentados na 5ª Conferência Internacional de Psicologia Comunitária (CIPC, que foi realizada em setembro de 2014 em Fortaleza (Ceará/Brasil. O tema da 5ª CIPC foi “Psicologia Comunitária no mundo atual: desafios, limites e práticas” com 1553 inscritos e 726 trabalhos aprovados. A metodologia consiste em analisar a temática da pobreza nos trabalhos aprovados nos cincos eixos temáticos: Políticas Públicas, Acadêmico/Formação, Profissão, Movimentos Sociais e Ética na dimensão planetária e em defesa da vida. As dimensões analisadas foram: concepções de pobreza, dimensões psicossociais utilizadas e relação da Psicologia Comunitária com a pobreza. Analisa-se que os eixos com mais produções relacionadas à pobreza são Acadêmico/Formação e Políticas Públicas. Entretanto, a maioria dos resumos não apresenta uma definição específica da pobreza. Há também produções com enfoques monetários e multidimensionais. Sobre as dimensões da pobreza, as mais utilizadas foram o apoio social, as potencialidades, o fatalismo, a conscientização, a vergonha, a humilhação e a exclusão social. Sobre as relações da Psicologia Comunitária com a pobreza, grande parte dos resumos utilizam a pobreza somente como caracterização de um contexto, porém também há produções que atuam contra as práticas de opressão relacionadas à pobreza e em uma perspectiva crítica.

    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

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

    Simmonds, J.R.; Haywood, S.M.; Linsley, G.S.

    1982-10-01

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

    Full Text Available FUNDAMENTO: Anestesia para cirurgia cardíaca pediátrica é sistematicamente realizada em pacientes graves sob condições fisiológicas anormais. No intraoperatório, existem variações significativas da volemia, temperatura corporal, composição plasmática e fluxo sanguíneo tecidual, além de ativação da inflamação, com consequências importantes. Medidas seriadas da glicemia podem indicar estados de exacerbação da resposta neuroendocrinometabólica ao trauma servindo como marcadores prognóstico de morbidade nessa população. OBJETIVO: Correlacionar os níveis de glicemia do período perioperatório de crianças submetidas a cirurgia cardíaca com a ocorrência de complicações no pós-operatório e comparar os níveis intraoperatórios de glicemia de acordo com as condições perioperatórias. MÉTODOS: Informações referentes ao procedimento anestésico-cirúrgico e condições perioperatórias dos pacientes foram coletadas em prontuário. Comparações das médias dos valores perioperatórios da glicemia nos grupos de pacientes que apresentaram, ou não, complicações pós-operatórias e as frequências referentes às condições perioperatórias foram estabelecidas conforme cálculo da razão de chances e em análises univariáveis não paramétricas. RESULTADOS: Valores mais elevados de glicemia intraoperatória foram observados nos indivíduos que apresentaram complicações pós-operatórias. Prematuridade, faixa etária, tipo de anestesia e caráter do procedimento não apresentaram influência na média glicêmica do intraoperatório. O emprego de Circulação Extracorpórea (CEC esteve associado a maiores valores de glicemia durante a cirurgia. Nos procedimentos com CEC, maiores níveis glicêmicos foram observados nos indivíduos que evoluíram com infecção e complicações cardiovasculares, nas cirurgias sem CEC essa mesma associação ocorreu com complicações infecciosas e hematológicas.

    Accidental marine oil spill pollution can result in severe environmental, ecological, economic and other consequences. 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.

    2006-01-01

    As part of the DOE RIA R and D effort we investigated the possibilities and problems of beam strippers in the different heavy ion accelerator components of a possible Rare Isotope Accelerator (RIA) facility. We focused on two beam stripping positions in the RIA heavy ion driver where benchmark currents of up to 5 particle (micro)A 238-U were projected at energies of 10.5 MeV/u and 85 MeV/u respectively. In order to select feasible stripper materials, data from experiments with Uranium beams at Texas A and M and GSI were evaluated. Based on these results thermal estimates for a possible design were calculated and cooling simulations with commercially available software performed. Additionally, we performed simulations with the GEANT4 code on evaluating the radiation environment for our beam stripping solution at the 85 MeV/u position in the RIA driver

MÉTODO: Anestesia venosa total foi administrada a 60 pacientes adultos para obter níveis de BIS de 40-60. Os pacientes foram randomicamente divididos em três grupos, de acordo com as gravações que ouviram. Os pacientes do grupo categoria (CT ouviram uma fita gravada contendo cinco nomes de animais. Os pacientes do grupo recordar palavras (RP ouviram uma fita gravada contendo cinco palavras de frequência média na língua turca, depois de adaptadas. Os pacientes do grupo controle (GC ouviram os sons do mar até o fim da cirurgia. Duas horas após a cirurgia, os testes foram administrados a cada paciente na sala de recuperação para avaliar a memória. RESULTADOS: Houve uma diferença entre os escores dos grupos CT e GC no Miniexame do Estado Mental (MMSE; todos os escores foram > 20. Os resultados dos testes de categoria e recordar palavras, aplicados para avaliar a memória implícita, não foram estatisticamente diferentes entre os grupos. Não houve evidência de memória implícita em nenhum dos pacientes. Um paciente lembrou-se de ouvir "o som de água" como uma prova de memória explícita. Onze pacientes declararam não ter sonhado. CONCLUSÕES: Apesar de não termos encontrado nenhuma evidência de memória implícita sob anestesia adequada com AVT, um paciente apresentou memória explícita. Embora a profundidade adequada da anestesia fornecida pelo monitoramento do BIS corrobore nossos resultados para a memória implícita, ela não explica os resultados para a memória explícita.

    Full Text Available O objetivo deste artigo é analisar como a trajetória da Ação Popular (AP, organização de esquerda das décadas de 1960 e 1970, é narrada e interpretada por Duarte Pacheco Pereira, um dos mais importantes dirigentes de sua história. Caracterizada por sua origem heterodoxa, influenciada pelo humanismo cristão, pelo existencialismo e pelo marxismo, a AP estabeleceu, na conjuntura posterior a 1964, um processo de ruptura com seu passado e de adesão à tradição do marxismo-leninismo, que foi permeado por tensões e cisões políticas. Investigando a interface entre as suas memórias e a história da AP, procura-se aferir sua contribuição à interpretação da singular práxis dessa organização política. A análise tem o suporte de entrevistas concedidas por Duarte Pacheco Pereira, de uma palestra que ele proferiu e do fundo documental que leva seu nome, disponível no Arquivo Edgard Leuenroth.

    Full Text Available Resumo Neste artigo, discuto as interseções entre feminismo, memória e emoções no ambiente virtual da Internet. A metodologia consiste na análise das páginas dos projetos Aurélia e Let’s Celebrate Women, que se dedicam a construir uma memória coletiva feminina online, reunindo histórias de mulheres inspiradoras, do passado e do presente. O objetivo é problematizar os usos da memória pelos movimentos sociais, em suas constituições identitárias e em suas lutas por reconhecimento, identificando os imbricamentos presentes entre os feminismos contemporâneos e a Internet. A partir de uma discussão do conceito de memória, investigo, ainda, as relações entre essas iniciativas e o crescimento de uma cultura do lembrar na contemporaneidade. Na relação entre as práticas de rememoração e as emoções, o direito à memória se estabelece como uma reivindicação primordial das mulheres em suas novas formas de militância.

The informativeness ranking of sentences was evaluated in terms of nDCG (0.977) and correlation metrics (0.678-0.727) when compared to an annotator's ranked list. miRiaD, a high performance system that can capture a wide variety of microRNA-disease related information, extends beyond the scope of existing microRNA-disease resources. It can be incorporated into manual curation pipelines and serve as a resource for biomedical researchers interested in the role of microRNAs in disease. In our ongoing work we are developing an improved miRiaD web interface that will facilitate complex queries about microRNA-disease relationships, such as "In what diseases does microRNA regulation of apoptosis play a role?" or "Is there overlap in the sets of genes targeted by microRNAs in different types of dementia?"."

    A new competitive solid phase radioimmunoassay (CLB-RIA) has been developed for the detection of HBAg and HBAb in human serum and plasma. In the assay, sheep antibodies to HBAg, covalently linked to an insoluble carrier, highly purified /sup 125/I labelled HBAg and the serum or plasma sample are incubated for 20 h at room temperature. After incubation, the bound and the free fraction of the tracer are separated by centrifugation. The presence of both HBAg and HBAb results in a decrease of the amount of bound tracer, when compared with a negative control serum. Differentiation between HBAg and HBAb requires the use of another type of radioimmunoassay. For this purpose a sandwich solid phase radioimmunoassay, for the detection of HBAb only, has been developed (CLB-AURIA). In this, assay-purified HBAg is covalently linked to an insoluble carrier. Using a mixture of both immunosorbents (insolubilized HBAg and HBAb), it is possible to detect and to distinguish HBAg and HBAb in one single solid phase radioimmunoassay (CLB-MIRIA). The influence of three parameters on the CLB-RIA, the incubation time, the amount of tracer and the effect of Tween-20 has been studied. The sensitivity of the described solid phase CLB-RIA for the detection of HBAg is comparable to that of other radioimmunoassays reported in literature; its specificity is very high.

    Full Text Available No Brasil existem poucas informações sobre o aborto provocado e suas características na população. A dificuldade em se obter dados confiáveis deve-se: à sua ilegalidade, e também ao fato de que a maioria dos estudos é realizada em hospitais. Assim, em 1990, foi realizada pesquisa entre alunas da graduação e funcionárias de uma universidade brasileira. Os dados foram obtidos por meio de questionário, auto-respondido, para devolução por correio, anonimamente. Os resultados apresentados referem-se à freqüência do aborto provocado nesta população. Encontrou-se que quatro vezes menos alunas do que funcionárias tinham engravidado alguma vez (15% e 65%; 9% das alunas e 14% das funcionárias tiveram aborto provocado. Entre as mulheres que engravidaram alguma vez, as alunas tiveram mais aborto provocado do que as funcionárias (59% e 20%. Quando controladas por grupo etário as diferenças entre as alunas e funcionárias mantiveram-se. Entretanto, entre as alunas, o aborto provocado foi mais freqüente entre as mais jovens.

    Full Text Available How do we define, discuss or assess aesthetics within a contemporary philosophical framework? The indefiniteness that accompanies attempts to formalize a definition of the aesthetic is a primary focus of this paper. This lack of a definition has occupied philosophers for hundreds of years in attempts to delineate the boundaries of an elusively formless concept. This formlessness speaks to the incredibly evasive character of such a pervasive feature recognized in both natural and artificial systems, agents and artefacts. With the rapid growth of artificially intelligent systems and an astounding diversity in computational creativity, in what ways may we approach aesthetics? How is the aesthetic recognized, determined and produced? This paper seeks to critically engage issues of non-human agency, inter-object relations, and aesthetic theory in relation to computational entities and autonomous systems. The ability of these systems to operate outside of human cognitive limitations including thought patterns and constructions which may preclude alternative aesthetic outcomes, afford them in some ways limitless potential in relation to aesthetics. The designation of the accidental or provisional is utilized as an alternative approach to the production and assessment of aesthetic occurrences of the non-human.

    1994-01-01

    The effects of acute irradiations of a mixed pine and birch forest in spring and autumn with a high power point-type gamma radiation source (1180 TBq 137 Cs) have been described. Radiation dose relationships for numerous response reactions of woody and herbaceous plants (growth and development of organs of woody plants, cytogenetical, physiological and biochemical changes in trees, reproductive potential of plants, damage and dying off of the forest as a biogeocenosis on the whole) have been calculated. Post-radiation recovery of the forest was investigated. Changes involving the secondary reactions related to radiation damage and death of the trees are presented. A model for radiation damage of forests has been designed. Examples are given on the usage of this model in the description of radiation effects in forests in the event of accidental releases of radionuclides into environment

    Full Text Available O artigo investiga a estruturação de uma nova cultura de memória, a qual inverte a lógica metafísica com que se pensou a relação entre tecnologia e experiência nas ciências sociais. Com as recentes tecnologias da vida e da informação, a concepção do corpo humano como algo que se constitui à margem de um aparato tecnológico declina em credibilidade. Com isso, um dos principais projetos da metafísica ocidental, a saber, a estruturação de um campo de experiência e conhecimento livre de suportes técnicos, malogra em seu humanismo tecnofóbico. A partir de uma apreciação do conto Memento Mori, de Jonathan Nolan, e do filme Amnésia, de Christopher Nolan, analiso a relação entre memória e escritura, corpo e arquivo na contemporaneidade. O objetivo é perceber as tensões e oscilações implícitas na tentativa de instauração de uma mnemotécnica pretensamente pós-humana ou pós-orgânica.

    The present paper evaluates some of thermodynamic parameters by using RIA (radioimmunoassay) method. The RIA systems studied were: 1) antiprogesterone antibody-progesterone- 3 H; 2) antiprogesterone antibody-progesterone- 125 I. The antigen (progesterone) was labelled with 3 H, in the first case, and 125 I in the second one (progesterone- 125 I was progesterone-6-S-CH 2 -CO-histamine- 125 I). RIA reactions were developed at two temperatures: 277 K and 296 K. Samples of antiprogesterone antibodies and labelled progesterone were incubated with different amounts of unlabeled progesterone. The immune complex was precipitated after reaching the chemical equilibrium and its radioactivity measured at γ-counter. By the radioactive measurements, the affinity constants (K S ) were estimated. The values of the affinity constants were used to estimate the thermodynamic parameters of the systems, such as: enthalpy (ΔH), Gibbs energy (ΔG) and entropy (ΔS). (authors)

    2012-01-01

    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)

Com a finalidade de marcar o sistema arterial dos espécimes, o tronco braquiocefálico esquerdo foi canulado e injetado com solução aquosa de látex corado. Posteriormente, procedeu-se a fixação das aves com solução aquosa de formol 10% e a dissecação com instrumentos adequados, obtendo-se os resultados a seguir. A artéria celíaca originou-se da face ventral da aorta descendente. O primeiro ramo colateral surgiu da própria artéria celíaca, constituindo a artéria esofágica. Posteriormente, artéria celíaca se bifurcou em dois ramos, denominados ramo esquerdo da artéria celíaca e ramo direito da artéria celíaca. O ramo esquerdo emitiu a artéria proventricular ventral, seguida das artérias esplênicas, da artéria proventricular dorsal e da artéria hepática esquerda. Por fim, o ramo esquerdo se bifurcou, originando as artérias gástricas ventral e esquerda. O ramo direito emitiu a artéria hepática direita, seguida da artéria ileal e da artéria gástrica direita. Por fim, o ramo direito prosseguiu como artéria pancreaticoduodenal. Os achados deste trabalho apresentaram grande similaridade com as linhagens de aves da espécie Gallus gallus, exceto pela ausência da artéria ileocecal, de ramos císticos e da artéria gástrica dorsal.

    The primary goals of this study, were to identify the posttraumatic growth (PTG) level of accidentally injured Chinese patients shortly after an accident occurred and to determine whether cognitive processing, self-disclosure, and psychosocial resources predicted PTG. A total of 232 patients were recruited from two public hospitals in Shanghai within the first three months of an accidental injury. Patients completed self-report questionnaires to assess severity of injury, cognitive processing, self-disclosure, psychosocial resources, and PTG. Patients reported a mid-low level of PTG (M = 50.38, SD = 18.12) in the short length of time post-injury. Hierarchical regression analysis indicated that subjective accident severity, deliberate rumination, perceived social support, and attitude towards disclosure were strong predictors of PTG. A moderating role of self-disclosure between intrusive rumination and PTG was identified. These findings support an interaction effect of rumination and self-disclosure on PTG and have implications for early intervention of accidentally injured patients.

    2015-04-01

    This work approaches the natural littoral processes and their changes induced by human activities around the Cantabrian RIA of FOZ (Galicia, NW Spain). Ria is a specific Spanish term for referring the estuary figured on the sea flooded mouth of a river valley. Although located in Galicia the RIA of FOZ is a Cantabrian Ria. The "Cantabrian rias" clearly differ from the "Galician rias" in their lower degree of tectonic complexity, in their smaller dimensions and in their more advanced current state of infilling (Diez, 1996). While Galician is a Pacific coast Cantabrian was generated as a mainly Atlantic coast. The sedimentary deposits of the Cantabrian rias are mainly from marine origin, being from fluvial origin (Asensio, 1979) just the finest components. The predominant Cantabrian littoral transport goes eastwards and, as consequence of it, the sedimentary littoral spits closing the mouths in coasts normally grow in the same sense. But there are many cases, like in the Ria of Foz, where the spit progresses in an apparent westwards atypical way. This work shows that it is due to combined wind wave phenomena of refraction, diffraction and reflection, which will be detailed. But the human activities interfere in these natural processes. Different port constructions have been made in the Ria of Foz from 1931 to 1977. Their final effects in the morph-dynamics obligate to introduce one construction for regenerate the spit in 1986. The performance, effectiveness and impact of all these port constructions are studied in detail and what are their influences in natural processes for finally applying this knowledge in risks management. Keywords: Rias, Littoral processes, Coastal morph-dynamics, Human induced driving, Risk management.

    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.

    Full Text Available Este artigo trata as fontes primárias à luz de uma epistemologia que submete a investigação e a pesquisa à ação desconstrutora dos sujeitos: as fontes, por isso, saem da posição de "ponto primacial" para a de "ponto relacional". E, aí, a linguagem se transforma em relação de intertextualidade, pois a contradição marca o sentido da interdependência e, nisso, a significação põe a força da instabilidade na relação do sujeito com o objeto. Este, aliás, aberto à abordagem múltipla do real, integra a relação de interdisciplinaridade, e, assim, vêm surgindo, por exemplo, explicações iluminadoras com as articulações de Educação, Pedagogia, Linguagem, História.

  18. A review of experiments and computer analyses on RIAs

    International Nuclear Information System (INIS)

    Jernkvist, L.O.; Massih, A.R.; In de Betou, J.

    2010-01-01

    Reactivity initiated accidents (RIAs) are nuclear reactor accidents that involve an unwanted increase in fission rate and reactor power. Reactivity initiated accidents in power reactors may occur as a result of reactor control system failures, control element ejections or events caused by rapid changes in temperature or pressure of the coolant/moderator. our current understanding of reactivity initiated accidents and their consequences is based largely on three sources of information: 1) best-estimate computer analyses of the reactor response to postulated accident scenarios, 2) pulse-irradiation tests on instrumented fuel rodlets, carried out in research reactors, 3) out-of-pile separate effect tests, targeted to explore key phenomena under RIA conditions. In recent years, we have reviewed, compiled and analysed these 3 categories of data. The results is a state-of-the-art report on fuel behaviour under RIA conditions, which is currently being published by the OECD Nuclear Energy Agency. The purpose of this paper is to give a brief summary of this report

  20. Risk factors for unnatural death: Fatal accidental intoxication, undetermined intent and suicide: Register follow-up in a criminal justice population with substance use problems.

    Olsson, Martin O; Bradvik, Louise; Öjehagen, Agneta; Hakansson, Anders

    2016-05-01

    Risk factors for suicide and fatal accidental intoxication are extensively studied, while risk factors for intoxications/injuries of undetermined intent are less well known. The latter have shown an overlap with suicides, but also with fatal accidental intoxications. The objective was to analyze potential differences and similarities in the patterns of risk factors for accidental intoxications, injuries/intoxications with undetermined intent, and suicides, respectively. A follow-up register study was conducted, using data from ASI interviews with clients in the criminal justice system in Sweden (n=6744), followed in the National Causes of Death Register. A set of risk factors from the ASI interview were tested in bivariate analysis with the respective cause of death, yielding significant risk factors further analyzed in three Cox regression models. In Cox regression analyses, death from fatal accidental intoxication was associated with male gender (HR 4.09), use of heroin (HR 2.86), and use of cannabis (HR 1.94), and death from intoxication/injury of undetermined intent was associated with use of heroin (HR 3.48), binge drinking of alcohol (HR 2.46) and previous psychiatric hospitalization (HR 2.41), while negatively associated with depression (HR 0.33). Death from suicide was associated with previous suicide attempts (HR 2.78) and use of sedatives (HR 2.17). In this population of criminal justice clients with reported substance use problems, fatal injuries/intoxications with undetermined intent - like fatal accidental intoxications - appear to be associated with substance use variables, and cannot readily be assumed to represent the same background factors as suicide.

  1. Regionalized study of the impact of an accidental radioactive pollution on a permanent meadow

    International Nuclear Information System (INIS)

    Durand, V.; Mercat-Rommens, C.

    2006-01-01

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

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

    2015-01-01

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

  3. Accidental degeneracy in k-space, geometrical phase, and the perturbation of π by spin-orbit interactions

    2018-06-01

    Since closed lines of accidental electronic degeneracies were demonstrated to be possible, even frequent, by Herring in 1937, no further developments arose for eight decades. The earliest report of such a nodal loop in a real material - aluminum - is recounted and elaborated on. Nodal loop semimetals have become a focus of recent activity, with emphasis on other issues. Band degeneracies are, after all, the origin of topological phases in crystalline materials. Spin-orbit interaction lifts accidental band degeneracies, with the resulting spectrum being provided here. The geometric phase γ(C) = ± π for circuits C surrounding a line of such degeneracy cannot survive completely unchanged. The change depends on how the spin is fixed during adiabatic evolution. For spin fixed along the internal spin-orbit field, γ(C) decreases to zero as the circuit collapses around the line of lifted degeneracy. For spin fixed along a perpendicular axis, the conical intersection persists and γ(C) = ± π is unchanged.

    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

    2006-01-01

    The determination of progesterone concentration in whole and fat-free milk 19-24 days after conception enables to distinguish fertile and non-fertile insemination, which is important in cattle breeding. The aim of this work was to develop a simple and quick radioimmunoassay test for the determination of progesterone in cow milk. Two types of solid-phase tubes coated with specific polyclonal anti-progesterone antibody from ORION Diagnostica and BIOSOURCE International, two different progesterone derivatives viz. progesterone-3- carboxymethyl oxime (CMO) and progesterone-11α-hemisuccinate (HS) conjugated to 125 I-histamine and the HPLC system with Lichrospher RP-18 column along with 65% acetonitrile/water as eluent to purify the tracers were used to carry out this work. Progesterone-3CMO- 125 I-histamine had a retention time of 13.2 min and progesterone-11α-hemisuccinate- 125 I-histamine had a retention time of 7.8 min. Two kinds of kits (kit I and kit II) were prepared, first with progesterone-3CMO- 125 I-histamine as the tracer and coated tubes from Progesterone Veterinary RIA kit of ORION Diagnostica and the second with progesterone-11αHS- 125 I-histamine as the tracer and coated tubes from Progesterone Veterinary RIA kit from BIOSOURCE International. Progesterone from Sigma and selected fat-free cow's milk without progesterone as zero progesterone milk matrix were used for standard preparation. The optimal assay procedure was as follows: 50μL standards, controls and fat-free milk samples were pipetted into coated tubes followed by addition of 500μL of diluted tracer. The tubes were incubated for 2h in case of kit I and 3h for kit II at RT. After the incubation, the tubes were decanted and counted. The assay range was 0 to 270 nmol/L for kit I and 0 to 300 nmol/L for kit II. The sensitivity of the kit with ORION coated tubes was better (0.8 nmol/L) than that of BIOSOURCE tubes which was 1.5 nmol/L. Validation of these assays in terms of specificity, accuracy

    Hydroxychloroquine is an oral antimalarial medication commonly used off-label for a variety of rheumatological conditions, including systemic lupus erythematosus, rheumatoid arthritis, Sjögren's syndrome and dermatomyositis. We present a case of a 64-year-old woman who presented with acute onset headache, bilateral tinnitus, and left-sided facial numbness and tingling in the setting of accidentally overdosing on hydroxychloroquine. By the next morning, the patient began to experience worsening in the tingling sensation and it eventually spread to her left arm, thigh and distal extremities. The patient also complained of new onset blurring of her peripheral vision and feeling 'off balance.' Despite a complete neurological and ophthalmological work-up with unremarkable imaging and blood work, the patient has had no improvement in her tinnitus, left-sided paresthesias, visual disturbance or ataxia. This is a unique case of hydroxychloroquine overdose resulting in permanent neurotoxic vestibulopathy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Full Text Available Non-accidental deaths in children in Kuala Lumpur, Malaysia are not uncommon, and they are often reported for identification of injuries. Five case series in children are presented here with typical injuries of differing ages in child abuse. Where history was partially hidden from the real scenario, involvement of family members was inevitable. The injuries were particularly diversified from a single unprecedented injury to multiple severe injuries, which led to the deaths of children less than 3 years of age. The discussion revolved around the autopsy and ancillary investigations in the context of urban perspectives in Kuala Lumpur area.

    Full Text Available Compósitos de cimento-borracha de pneus preparados com cimentos tipo I e contendo adições de três diferentes escórias foram estudados. Resistência à flexão, absorção de água e resistência ao ataque ácido foram investigadas. Um decréscimo no módulo de ruptura (MOR foi observado para todos os corpos de prova contendo borracha, quando comparados com os corpos de prova sem borracha (controles. Para as pastas controle e com borracha e argamassas controle, preparadas com cimento com escória, o MOR aumenta com o aumento da atividade hidráulica da escória utilizada, até valores indistinguíveis dos obtidos para as argamassas e pastas preparadas com cimento tipo I. Argamassas com borracha apresentaram valores de MOR independentes do cimento utilizado. Uma redução na sorção de água é observada para corpos de prova controle e contendo borracha, preparados com todos os cimentos contendo adição de escória, quando comparados com os corpos de prova preparados com cimento tipo I. Para corpos de prova de argamassa com borracha, quanto mais baixa é a basicidade da escória, menor é a sorção de água dos compósitos. Estes resultados indicam baixa porosidade e consequentemente uma melhor adesão entre a borracha e a matriz de cimento nestes corpos de prova. Além disso, uma velocidade menor de sorção de água é observada para os corpos de prova com borracha, com destaque para os corpos de prova com cimento que contém a escória menos básica, quando comparados com os controles. Resultados de ataque ácido aos corpos e prova de argamassas, preparadas com os cimentos contendo adição de escória, mostram que a susceptibilidade dos corpos de prova frente à degradação por ácido é governada não somente por aspectos microestruturais, como porosidade e permeabilidade, mas também por aspectos químicos, como diferenças na quantidade de álcalis presentes nas escórias ou quantidade de escória não reagida nos corpos de prova

    2012-04-01

    Full Text Available Muito já se escreveu sobre Grande Sertão: Veredas, sobretudo a respeito do conceito de sertão como microcosmo, bem como, em termos de linguagem, da técnica narrativa do monólogo-diálogo. Neste artigo, pretende-se investigar os elementos de memória presentes na obra. O produto da tentativa do narrador-protagonista Riobaldo de entender o sentido de sua vida ao rememorar eventos tem como resultado um tipo de relato memorialístico. Ainda que tais eventos sejam ficção, Guimarães Rosa os situa em um plano temporal e espacial concretos, o que permite revelar um enquadramento social a partir dessa “memória individual” de Riobaldo enlaçada à memória coletiva do sertão. O diálogo teórico abarca dois textos básicos, o de Eduardo F. Coutinho, sobre Grande Sertão: Veredas, e os estudos de Marina Maluf sobre memória.
