Повний текст джерелаNo campo de batalha, é essencial o uso de vestes de elevado nível de protecção, nomeadamente dos capacetes. Hoje em dia, tenta-se melhorar a qualidade da protecção dos soldados através do uso de materiais mais resistentes à penetração do projecteis e fragmentos derivados do impacto. Para esta evolução ser possível, é necessário o estudo das consequências causadas por impactos balísticos, em diversos cenários, no soldado, mais concretamente na cabeça humana. No estudo dos impactos balísticos ¶e imprescindível a utilização da simulação numérica por elementos finitos para a previsão das suas consequências nas lesões causadas no ser humano. Este trabalho tem como principal objectivo a avaliação do nível de lesões cerebrais, através do Head Injury Criterion, provocadas pelo impacto balístico de um projéctil de calibre 7.62£51 mm no capacete militar PASGT. Também as acelerações inerentes a todo o fenómeno e as deformações causadas no capacete são avaliados. Para isso modelos CAD do capacete, do projéctil e de uma cabeça humana normalizada são utilizados para os ensaios simulados no programa LS-Dyna. Os ensaios consistem em estudar a influencia da orientação e direcção do projéctil no impacto. São feitos estudos de impactos a 0°, 22.5°, 45° e 67.5° quer na direcção horizontal quer na direcção vertical, em três posições do capacete, frontal, lateral e occipital. ABSTRACT: On the battle¯eld, the use of vests whith high level of protection, including helmets is essential. Today, there is a clear need to improve the quality of the protection of soldiers through the use of materials more resistant to projectile penetration and to fragments derived from the impact. To make this development possible, it is necessary to study the e®ects caused by ballistic impacts, on the soldier, especially in the human head, on various scenarios. In a ballistic impact study it is essential to use a numerical simulation by ¯nite elements method to predict the consequences on human injuries. This work has as main objective the assessment of the level of brain damages, using the Head Injury Criterion, caused on the impact of the ballistic pro- jectile 7.62£51 mm in PASGT military helmet. The accelerations derived from the whole phenomenon and the deformations caused on the helmet are also evaluated. For that, CAD models of the helmet, the projectile and a standardised human head are used to perform numerical simulations using LS-Dyna. The tests consists in studying the in°uence of projectile impact orientation and direction. Impacts studies are done at 0°, 22.5°, 45°and 67.5°, either in the horizontal and vertical directions at three helmet positions: front, side and occipital.

Повний текст джерелаChildren are road users in the same way as adults. According to the National Interministerial Observatory of Road Safety (ONISR), there were in 2010 on the French roads 67288 accidents of which 3992 killed in 30 days. Among those killed, there are 130 children under 14, including 30 children pedestrians. The protection of children is therefore a burning issue.In order to improve the protection of children, it is necessary to understand the mechanisms of injury involved in a pedestrian accident. To achieve this goal, different models, physical or numerical have been developed in recent years. This study has chosen to focus on the use of numerical models to deepen knowledge about the behavior of the child victim of a pedestrian accident because it offers the possibility of not being constrained from an ethical point of view and but also to multiply the conditions of possible tests.The objective of this Thesis is to treat the problem of the pedestrian child and its protection in particular by evaluating the influence of the design of a vehicle on the injuries to the head of an impacted pedestrian child. As a first step, a child-specific head injury criterion was developed by reconstructing actual accidents and predicting the severity of injury (AIS). In a second step, a numerical tool able to realize a parametric study simulating pedestrian accidents was developed. The influence of the design of a vehicle on the lesions at the head of a pedestrian child has been studied

Nesta análise, dois problemas de otimização foram abordados, o primeiro onde a energia total transmitida ao cérebro mediante impacto deve ser reduzida e o segundo em que o valor do Head Injury Criterion deve ser reduzido, ambos os problemas sujeitos a restrições associadas a outros critérios de lesão e desempenho. O modelo utilizado para simular o comportamento da cabeça é o Translational Head Injury Model, o qual é um modelo de parâmetros discretos. O impacto é realizado na direção Anterior-Posterior. A força de controlo ótima exercida na cabeça foi determinada para condições de impacto especificas. As soluções para o primeiro problema de otimização não cumpriram as restrições definidas. O segundo problema de otimização foi resolvido com sucesso, com os melhores resultados para uma espessura de forro interno de 30 mm.
The Limiting Performance Analysis of a protection helmet for motorcyclist was performed, with the aim of establishing the optimum control force exerted by the material of the inner liner of this equipment on the user’s head, in the event of impact against a rigid surface, with the purpose of reducing injury severity and occurrence probability. In this analysis, two optimization problems are addressed, the first where the total energy imparted to the brain upon impact must be minimized and the second where the value of the Head Injury Criterion must be minimized, both problems bound to restrictions associated with other injury and performance criteria. The model used to simulate the behaviour of the head is the Translational Head Injury Model, which is a lumped parameter model. The impact is performed in the Anterior-Posterior direction. The optimum control force exerted on the head was established for specific impact conditions. The solutions to the for the first optimization problem didn’t meet the restrictions defined. The second optimization problem was solved with success, with the best results por an inner liner thickness of 30 mm.

Повний текст джерелаThe principal objective of this study is to enhance the existing finite element head model. A composite material model for skull, taking into account damage is implemented in the Strasbourg University Finite Element Head Model in order to enhance the existing skull mechanical constitutive law. The skull behavior is validated in terms of fracture patterns and contact forces by reconstructing 15 experimental cases in collaboration with Medical College of Wisconsin. The new skull model is capable of reproducing skull fracture precisely. The composite skull model is validated not only for maximum forces, but also for lateral impact against actual force time curves from PMHS for the first time. This study also proposes the implementation of fractional anisotropy and axonal fiber orientation from Diffusion Tensor Imaging of 12 healthy patients into an existing human FE head model to develop a more realistic brain model with advanced constitutive laws. Further, the brain behavior was validated in terms of brain strain against experimental data. A reasonable agreement was observed between the simulation and experimental data. Results showed the feasibility of integrating axonal direction information into FE analysis and established the context of computation of axonal elongation in case of head trauma. A total 125 reconstructions were done by using the new advanced FEHM and the axonal strain was found to be the pertinent parameter to predict DAI

Повний текст джерелаPedestrian safety is a worldwide concern, which needs to be investigated by both vehicle manufacturers and researchers to approach innovative solutions. In car-Pedestrian accidents, lower limbs have been demonstrated to be the most frequently injured body region of the pedestrian. Given the biomechanical features of lower limbs, how the existing injury criteria could be improved to aid the development of a pedestrian friendly car? The current study aims to promote significant improvements in the injury criteria of lower limbs for pedestrian safety combining experimental tests and numerical simulations. A finite element lower limb model (LLMS model) was used and improved to investigate the mechanical responses of lower limbs in the loading conditions reflecting the car-Pedestrian impact. A particular attention was paid on the model ability of predicting separately the injuries of long bones and knee joints to develop the corresponding injury criteria. With regard to the tibia structure and its loading condition in pedestrian accidents, we proposed a quadratic curve of bending moments to tibia locations as its injury tolerance. Given dominant injury mechanisms of the ligaments, the knee injury criterion was established as a function of combined joint kinematics including lateral bending and lateral shearing. Moreover, these criteria are relevant with the previous and current experimental test results. Finally, the efficiency of the proposed criteria was evaluated by a parametric study of the realistic car-Pedestrian impact conditions

Exponer la prevalencia, factores de riesgo y mortalidad asociada a Injuria renal aguda (IRA) séptica dentro del ámbito de Unidad De Cuidados Intensivos 2C del Hospital Edgardo Rebagliati Martins. Se seleccionó Historias clínicas de Pacientes con diagnóstico de ingreso de Sepsis durante el periodo de Noviembre 2012 hasta Mayo 2013, no incluyo en el estudio aquellos pacientes cuyas historias no se encontraban en Archivo General así como aquellas con Antecedentes de Insuficiencia renal crónica y menores de 18 años. El número total de Historias revisadas correspondió a 88 de los cuales encontramos 38 casos de IRA séptica y 50 casos de Sepsis sin IRA, basándonos en el criterio RIFLE. Se definió IRA aquellos pacientes que presentaron elevación aguda de la creatinina sobre 1.5 veces sobre los niveles basales previo ingreso a Unidad de Cuidados Intensivos, basándonos en el Criterio RIFLE del ADQI y se graduó la severidad en tres escalas Riesgo, Injuria y Falla. La información recogida de Historias clínicas fue analizada por el programa estadístico SAS. Se identificó una prevalencia de 43.2% de Injuria renal aguda en sépticos siendo distribuido según criterio RIFLE 6.8% para Riesgo, 19.3% para Injuria y 17.0% para Falla renal. Se encontró diferencias estadísticas; los pacientes con IRA por lo general fueron mayores y tuvieron mayor peso con respecto a los que no desarrollaron IRA. La hipertensión arterial fue encontrada con más frecuencia en los pacientes con IRA (OR 3.94 IC 95% 1.56 – 9.92), considerando un factor de riesgo. Los pacientes con IRA presentaron mayor severidad de enfermedad al ingreso demostrada en diferentes scores APACHE, SOFA, APACHE no renal y SOFA no renal con medias mayores con sus pares sin IRA. En cuanto a las variables de laboratorio al ingreso, los pacientes con IRA tuvieron niveles menores de bicarbonato y PaO2/FiO2 pero mayores niveles de lactato, urea, creatinina y potasio. En cuanto al resultado más importante, la IRA séptica se asocio a mayor mortalidad dentro de UCI (47.36% vs 26% OR 2.561 IC 95% 1.044 – 6 .282 con p = 0.045) con respecto a la Sepsis sin IRA. Se hallo cierta correlación linear con el grado de severidad del RIFLE con respecto a la mortalidad. (16.66% para Riesgo, 35.29% para Injuria y 73.33% para Falla), sin embargo solo para Falla (RIFLE F) fue estadísticamente significativo (p = 0.0017) La Injuria renal aguda séptica tiene una alta prevalencia, se asocia a paciente con mayor grado de severidad de enfermedad. La IRA séptica se asocia a mayor mortalidad.

Повний текст джерелаIt is well know that in case of accident the head does not only impact perpendicularly to the impacted structure but presents an oblique impact condition. However none of the today helmet standards do integrate oblique impacts with the recording of the dummy head rotational acceleration. An essential aspect of the present research is to simulate real world accident and to compute the victim’s kinematic in order to extract the head impact conditions. In collaboration with University Florence (Italy) 19 cases were considered and it was shown that the head impact velocity vector presents a significative angle. A novel helmet test method has been proposed. Helmeted headfoml is impacting a 45° inclined anvil at a speed of 8.5 m/s and the 6D acceleration versus time curves are introduced into an existing head FEM in order to compute the axon strains and to derive the brain injury risk

The method to measure the injuries in the head of the pedestrian will be made through a finite element model of a standard head in accordance with the European committee of improvements of the security of vehicles. The values of decelerations obtained in the analysis are compared with human tolerance levels according to HIC criteria (Head Injury Criteria), created by NHTSA (National Highway Traffic Safety Administration). Based on the finite element analysis results, this study demonstrate the influence of different hood inner panels and recommends the best structure to be applied by automobile industry.

Повний текст джерелаAutomakers are lawfully required to achieve a minimum level of security which is checked during standardized crash tests. This results in a limited number of scenarios, which do not take individual specificities into account. This dissertation evaluates real human behaviour during the pre-crash phase, by means of a driving simulator. The experiment, integrating an unavoidable accident, studied the behaviour of 76 drivers, of which 40 drivers on a dynamic simulator. Concerning this group, 43 acquisition channels dedicated to drivers were added. From the results, one can retain that the crash can be predicted for half of the drivers through the observation of their behaviour and their interaction with the car. Due to swerving manoeuvres, 25% of the drivers have their forearm just in front of the steering wheel at the time of crash. This situation may compromise the efficiency of the airbags, that is verified experimentally on a static bench, by the deployment of airbags in front of a Hybrid III-50% dummy. The throwing of the arm causes an impact of 120 g to the head. In a second stage, the integration of left upper limbs from PMHS reveals that the situation is likely to generate fractures in the forearm. A numerical model has been designed to estimate the consequences of the atypical position during a frontal crash at 50km/h. The head acceleration reaches 270 g, synonymous with high lesion risks. Finally, a technological modification of the airbags is proposed to reduce this risk. The assumption is made that the use of remote sensors technologies can allow an early detection of the crash and therefore slower triggering of airbags. Tested experimentally and then numerically, this technical evolution reduces the violence of the impact to respect the injury criteria

As automobile improved, they have become one important transportation means for modern people. While the use of automobile increases, the accidents happen more frequently. Automobile accidents normally would cause injuries to humans. Among accidental causalities due to vehicle crash, pedestrian fatalities constitute a large portion. Therefore, there is a need to improve pedestrian safety. Previous studies show that more than 50% of pedestrian fatalities are caused by head injuries, most of which are due to impact with the hood or windshield. Besides, in our country we record and measure the accident data in an artificial way, which usually leads to problems of incorrect measurement and incomplete data collection. This study uses the PC-Crash simulation software to analyze the Head Injury Criterion of the pedestrians in traffic accidents. These accidents reconstruction data can thus be applied by the authorities concerned as the major reference. The first part of the study explores vehicle type’s influence on pedestrian safety. Two major types of vehicle, car and bus, are used. The responses in kinematics and dynamics are described. Based on the results, the possible head injuries of the pedestrians are discussed. Since the nature of direct impact, the interacting properties between pedestrian segments and vehicle components are central to pedestrian impact, the second part of the study is to discuss pedestrian safety’s relevance with vehicle parameter and pedestrian parameter. Vehicle parameter includes type, mass and velocity. Pedestrian parameter includes height and weight. The study uses RBF to train the vehicle and pedestrian parameters. After training, the closer the trained output HIC is to the expected value, the better the performance is. Overall, using PC-Crash software will increase the quality and credibility of accident authentication and helps in reducing head injuries and social cost.

Designing for the vehicle safety is intent to reduce the severity of injury to passengers or to the vehicles. The study uses injury index of dummy as a design criteria to improve the vehicle safety. Among all the crashes, the frontal impact has one of the highest occurrence rates; therefore, the frontal impact is used as the major functional performance considered for the design improvements. In the study, dummy Hybrid III is used. The analysis results are compared with those in the literature to verify the accuracy of the analysis model, and then the analysis model is further used for optimization to improve the crashworthiness of the vehicle using injury index of the dummy. The results from the study show the thickness and shape of the front rail have great effect on the vehicle crashworthiness. After the optimization, the dummy head injury index is reduced more than 10%, and the injury scale is improved from level 1 to a smaller and better scale of level 0.

Повний текст джерелаA responsabilidade civil extracontratual é aquela que surge da violação de direitos de um qualquer indivíduo ao qual seja reconhecida eficácia erga omnes. Para que se esteja diante de uma situação geradora de responsabilidade civil e, consequentemente, da obrigação de indemnizar, a lei exige que se verifiquem os seguintes requisitos cumulativos: facto, ilicitude, culpa, dano e nexo de causalidade. Em sede de direito civil, é na responsabilidade civil delitual por factos ilícitos que se insere a responsabilização por danos produzidos a outrem, por exemplo, no âmbito de um acidente de viação. A prática de um facto ilício pode produzir danos temporários e danos permanentes, sendo que somente existirão danos permanentes caso não haja cura. Um dos parâmetros avaliados, quer seja o lesado uma criança quer seja um adulto, é o rebate profissional. A problemática que nos ocupa na presente Dissertação tem que ver com o critério a utilizar para o cálculo da indemnização pelo rebate profissional a que as sequelas verificadas em crianças representarão na vida laboral futura, atendendo a que no momento dessa aferição se desconhece qual será a profissão desempenhada, a idade de ingresso no mundo laboral e a remuneração. Dadas estas incógnitas não será justo para o lesante que se eleja a teoria da diferença (como acontece no caso dos adultos), sob pena do juízo prognose conduzir a um enriquecimento indevido do lesante. Assim, e após a consulta de acórdãos dos nossos Tribunais Superiores, culmina o nosso breve trabalho com a proposta de ser o cálculo da indemnização pelo rebate profissional remetida para decisão posterior aquando do ingresso do lesado na vida laboral e, utilizando fator o salário médio da área de estudos, a teoria da diferença e a equidade, determinar o montante.
Non-contractual civil liability is one which arises from the violation of the rights of any individual to whom erga omnes effectiveness is recognized. In order to face a situation that generates civil liability and, consequently, the obligation to indemnify, the law requires the following cumulative requirements to be verified: fact, illegality, fault, damage and causal link. In civil law, it is the criminal liability for illicit facts that includes liability for damages caused to others, for example, in the context of a road accident. The practice of an unlawful act can produce temporary damages and a permanent damages, and there will only be permanent damages if there is no cure. One of the parameters evaluated, whether the child is injured or an adult, is professional rebate. The problem that occupies us in this Dissertation is the criterion to be used to calculate the compensation for the professional impact that the sequelae observed in children will represent in the future working life, given that at the time of this assessment, it is unknown what the profession will be performed, the age of entry into the world of work and remuneration. With these unknowns facts, it is not fair for the injured person to apply the difference theory (as it happens in the case of adults), because the prognostic judgment can create an undue enrichment of the injured person. Thus, and after consulting the decisions of our Superior Courts, our brief work culminates with the proposal to send the calculation of the indemnity for the professional rebate to a later decision when the injured person enters the working life and determine the amount using the average salary factor of the area of study, the difference theory and equity.

In this study, autosomal dominant polycystic kidney disease (ADPKD) in feline and the prognosis of acute renal failure in canine were the main topics to be investigated. In chapter I, results of recent studies in both human and feline ADPKD as well as the methods for evaluating the prognosis of renal failure were introduced. In chapter two, establishment of a molecular method derived from multiplex amplification refractory mutation system-PCR (ARMS-PCR) for detection of feline ADPKD was described. By using three primers, ARMS-PCR successfully detected the point mutation of exon 29 in feline PKD1 gene from 35 feline blood samples, including 15 mutant cats and 20 wild type cats. The result was validated with that of automated sequencing; 100% of specificity was revealed, indicating that this method is not only advantaged with convenience and low cost but also with high sensitivity and specificity. In chapter three, we tried to use the RIFLE (risk, injury, failure, loss and end-stage) criteria, derived from human medicine, to evaluate prognosis of 853 dogs with acute kidney injury (AKI) by retrospective study. Taking the dogs in class Risk as the reference, mortality rate of the dogs either in class Injury or in class Failure was significantly higher than that of the dogs in class Risk (p < 0.05). In addition, we also generated a new score, which was combined with RIFLE criteria with other two factors, i.e. the level of serum phosphorus and diarrhea. Consequently, the statistic results revealed that the RIFLE criteria could be applied in veterinary medicine for classification of dogs with AKI and the new score had a better performance in prediction of prognosis than RIFLE criteria alone. In chapter four, conclusions and perspectives of our study were described. The application of the new diagnostic method or the evaluation criteria derived from human medicine can benefit veterinarians and also provide animal model for human medicine.

Повний текст джерелаThe prevalence of postconcussion syndrome following mild traumatic brain injury in developed countries varies from 40% to 80% during the first weeks after injury. However, as many as 50% of patients report symptoms for up to 3 months and 10-15% of them for more than a year. Mild head injuries and postconcussion syndrome represent a very serious public health issue, as estimates of occupational disability range from 12% at 2 months to 20% at 1 year, with severe concomitant social and financial impact. The objective of this study is to determine the characteristics and estimate the prevalence of postconcussion syndrome in an adult Greek population and to reveal demographics and injury characteristics concerning exclusively mild head injuries in the same cohort. Material-Methods: This prospective study was undertaken in the University Hospital of Patras in Western Greece. Recruitment of patients with mild traumatic brain injury began on May 2006 and finished on May 2008. Five hundred and thirty nine patients (539) with mild head injury were randomly recruited. Overall, 223 patients (223/539: 41,5%) (male 63% and female 37%) met the inclusion criteria of the ΄΄Colorado Medical Society Guidelines΄΄ for concussion, with median age 30 years (range: 18.5-57.5). The patients had a follow-up through telephone interviews at 1, 3 and 6 months post-injury and were asked about having any of the common postconcussion symptoms (ICD-10 criteria). Results: The rate of postconcussion syndrome at the end of the first, third and sixth month post-injury, was estimated at 10.3%, 6%, and 0.9%, respectively, which was 4-8 time less than other studies. Postconcussion syndrome was found to be more frequent among women (17%) and among individuals with bleeding diathesis (26%), compared with men and patients without clotting disorders, respectively. In addition, postconcussion syndrome affected in higher rates people who sustained assaults in comparison with other types of accident and was also more frequent among patients with posttraumatic anosmia. Conclusions: Our results are in contrast with previous studies in other developed countries, where the prevalence of the postconcussion syndrome was remarkably higher. The cultural differences regarding symptom expectation and the lack of compensation might explain the low rate of chronic symptoms in Greeks. To our knowledge, this is the first prospective study to estimate the prevalence of postconcussion syndrome among Greek adults and also the first trial in recording demographics and injury characteristics concerning exclusively mild head injuries in the same cohort. If further studies confirm our results in the future, reasonable queries could emerge, such as which patients really do suffer and whether their absence from work could have been avoided, as the cost of the lost productive work time after mild head injuries is extremely high.
