    The aim of this study was to develop a tool to calculate the insertion depth angle of cochlear implants, from computed tomography exams. The tool uses different image processing techniques, such as thresholding and active contour. Then, we compared the average insertion depth angle of three different implant manufacturers. The developed tool can be used, in the future, to compare the insertion depth angle of the cochlear implant with postoperative response of patient's hearing. (author)

MÉTODO: Foram estudadas, prospectivamente, 60 pacientes divididas aleatoriamente em 2 grupos. Todas receberam sedação pré-operatória com midazolam. Um dos grupos (P recebeu, antes de iniciar a cirurgia, 40 mg de parecoxib e o outro (T 20 mg de tenoxicam. Na sala de operação foi feita raquianestesia com bupivacaína e sufentanil. A analgesia pós-operatória foi avaliada mediante a intensidade da dor com escalas verbal e visual, a localização da dor (incisional, visceral, no ombro e o consumo de analgésicos suplementares. Os efeitos colaterais adversos foram registrados. A satisfação da paciente com a técnica foi pesquisada. RESULTADOS: A qualidade analgésica foi excelente, com 76% das pacientes do grupo P e 83% das pacientes do grupo T sem queixa de dor nem uso de analgésicos no pós-operatório. Não houve diferença entre os grupos em todos os critérios e períodos de avaliação analgésica. A incidência de efeitos adversos foi pequena, embora prurido de intensidade leve e curta duração tenha ocorrido freqüentemente. Todas as pacientes ficaram satisfeitas ou muito satisfeitas com a técnica empregada. CONCLUSÕES: Uma técnica de analgesia multimodal, com um componente de anestésico local e opióide por via subaracnóidea associado a AINE venoso, produz analgesia pós-operatória de excelente qualidade com poucos efeitos colaterais adversos em cirurgia videolaparoscópica ginecológica ambulatorial. A escolha do AINE não parece importante para obter estes resultados.JUSTIFICATIVA Y OBJETIVOS: Evaluar las características de la analgesia pos-operatoria en pacientes sometidas a cirugía ginecológica videolaparoscópica ambulatorial, comparando el efecto de parecoxib y

    Due to the increasing number and improved survival of lung transplant recipients, radiologists should be aware of the imaging features of the postoperative complications that can occur in such patients. The early treatment of complications is important for the long-term survival of lung transplant recipients. Frequently, HRCT plays a central role in the investigation of such complications. Early recognition of the signs of complications allows treatment to be initiated earlier, which improves survival. The aim of this pictorial review was to demonstrate the CT scan appearance of pulmonary complications such as reperfusion edema, acute rejection, infection, pulmonary thromboembolism, chronic rejection, bronchiolitis obliterans syndrome, cryptogenic organizing pneumonia, post transplant lymphoproliferative disorder, bronchial dehiscence and bronchial stenosis.

    The increase in human longevity caused a number of diseases with age; in contrast the advancement of medicine made possible the early diagnosis and treatment of several previously incurable diseases. This scenario is also important for domestic animals (dogs and cats - PETs) that have doubled their life expectancy in recent decades, a fact that humans took centuries to reach. Like humans, this increase in animal longevity was accompanied by age-related diseases, including cancer. One of the therapies currently used in the treatment of cancer is radiation therapy, a technique that uses ionizing radiation to destroy tumor cells (target volume) with minimal impairment to healthy surrounding tissues (organs at risk). This technique requires periodic quality control testing, including dosimetry with the use of tissue-equivalent phantoms, in order to verify the dose of radiation received by the patient being treated and to compare it subsequently with the calculated radiation dose by the treatment planning system. The rapid expansion of the 3D printer opened the way for a health revolution. planning for the spatial location and mapping of the isodose curves, thus realizing a more personalized planning for each radiation field, besides the preparation of dental implants, customization of prostheses and build of bolus. This work aimed has designed and developed a simulator object called 'Canis Morphic' using a 3D printer and tissue-equivalent materials to perform quality control and dose optimization tests in the area of Radiation therapy in animals (dogs). The results obtained demonstrated be promising in the area of development of phantoms by 3D printing, with materials of low cost, for application in quality control in Veterinary Radiation therapy.

    Assuming the systems planning radiotherapy recognize all body structures of the same density (d=1 g/cm³), variations in electron density within the irradiated area, as is the case of patients who undergo reconstruction mammary processes and use tissue expanders, may influence the dose distribution in the treatment and may produce heterogeneities which are not measured by changing its actual distribution into healthy tissues or in the target volume to be irradiated. Through the calculation of the algorithms' dose distribution of the XiO® planning system (Fast Fourier Transform, Convolution, Superposition, Fast Superposition e Clarkson), when using correction of heterogeneity between tissues of different densities, there was obtained a percentage ratio of dose increase in the structures of interest, and of the amount of absorbed dose by healthy organs adjacent to the target volume.

    The most common sequelae in head and neck cancer patients submitted to radiotherapy (60Cobalt) is postirradiation hypo salivation. This leads to a change in oral physiology, and, as a consequence, the irradiated individual is susceptible to infections and caries lesions. The aim of this study was to evaluate the behaviour of stimulated whole saliva flow rate (SWSFR) during and after radiotherapy treatment for head and neck cancer by lateral opposed fields. Six samples of mechanically stimulated whole saliva were collected of each individual and evaluated by gravimetric method.The first sample was collected before radiotherapy; the second one after 1500 cGy dose; the third one after the last dose of treatment and the remainder samples in intervals of subsequent two months up to six months after the end of treatment. The SWSFR decreased in 50% after a dose of 1500 cGy (1/4 of received treatment). After radiation therapy, the SWSFR was 0,33 ml/min and after six months was 0,20 ml/min. These values represented, respectively, a decreasing in 64% and 78% of initial values (ANOVA, Tukey&apos;s Test p<0.05).Based in these results, the authors concluded radiotherapy when applied in malign neoplasms of the head and neck region by lateral opposed fields was able to decrease significantly salivary flow rate. Intensive preventive dental care during and after radiotherapy seems to be an useful tool to avoid radiation caries and their complications. (author)

    The purpose of this study was to assess the usefulness of magnetic resonance imaging (MRI) in the pre- and postoperative evaluation of patients with tetralogy of Fallot. Twenty patients aged 1 to 29 years were prospectively evaluated with black-blood and contrast-enhanced angiographic techniques, 11 with the classic form of tetralogy of Fallot and 9 with tetralogy of Fallot and pulmonary atresia. MRI studies provided adequate visualization of the aorta that was classified as dilated or not dilated, and definition of its position in all cases. The use of contrast-enhanced MR angiographic techniques provided excellent imaging of the main right and left pulmonary arteries. The results suggest that MRI, including contrast-enhanced angiography techniques, is a useful tool in the evaluation of patients with tetralogy of Fallot before and after cardiac surgery since it provides important anatomical information that is not always obtained with echocardiography. MRI can be considered an alternative to cardiac catheterization, particularly in the evaluation of the pulmonary vascular anatomy. (author)

    Within a radiotherapy room, in addition to the primary beam, there is also secondary radiation due to the leakage of the accelerator head and the radiation scattering from room objects, patient and even the room&apos;s shielding itself, which is projected to protect external individuals disregarding its effects on the patient. This work aims to study the effect of concrete shielding wall over the patient, taking into account its contribution on equivalent doses. The MCNPX code was used to model the linear accelerator Varian 2100/2300 C/D operating at 18MeV, with MAX phantom representing the patient undergoing radiotherapy treatment for prostate cancer following Brazilian Institute of Cancer four-fields radiation application protocol (0°, 90°, 180° and 270°). Firstly, the treatment was patterned within a standard radiotherapy room, calculating the equivalent doses on patient&apos;s organs individually. In a second step, this treatment was modeled withdrawing the walls, floor and ceiling from the radiotherapy room, and then the equivalent doses calculated again. Comparing these results, it was found that the concrete has an average shielding contribution of around 20% in the equivalent dose on the patient&apos;s organs. (author)

  7. Seguridad del paciente en Radioterapia Intraoperatoria: Impacto de los elementos controlados por el Radiofisico

    Science.gov (United States)

    Tarjuelo, Juan Lopez

    Introduccion: En la administracion de la radioterapia intervienen profesionales y equipos de tratamiento, por lo que existe el riesgo de error y se precisa que dicho equipamiento funcione conforme a lo esperado. A los radiofisicos les corresponde participar en las actividades de garantia o aseguramiento de la calidad, incluyendo el control de calidad de los equipos, y en la evaluacion de los riesgos asociados. La radioterapia intraoperatoria (RIO) es una tecnica radioterapica de intensificacion de dosis, altamente selectiva, dirigida a volumenes anatomicos restringidos durante el tratamiento quirurgico oncologico, basada en la administracion de una dosis absorbida alta por medio de un haz de electrones tras el examen visual directo del lecho tumoral. Como incorporar los ultimos avances en el refuerzo de la seguridad en radioterapia es una tarea ambiciosa y compleja, resulta mas concreta y de inmediata aplicacion su introduccion en la RIO. El objetivo es analizar los elementos que reducen los riesgos y aumentan la seguridad en la RIO y su dosimetria, y valorar la funcion del radiofisico en esta labor. Material y metodos: Se emplearon el planificador Radiance de GMV y el acelerador lineal de los tratamientos de RIO Elekta Precise, controlado con el verificador diario de haces Daily QA Check 1090 y medido con las camaras de ionizacion PPC 40, FC65-G y FC65-P de PTW-Freiburg, a su vez verificadas con fuentes radiactivas adecuadas de estroncio-90 modelos CDP y CDC de IBA Dosimetry. Se realizo un analisis de modos de fallo y efectos (failure mode and effect analysis, FMEA) con el fin de identificar los elementos que forman la RIO y aplicar las herramientas necesarias para la minimizacion de los riesgos y la mejora de la seguridad en la tecnica. Se estudiaron las verificaciones diarias de dicho acelerador Precise con el control estadistico de procesos (statistical process control, SPC) y se simularon intervenciones para devolverlo al estado llamado en control.

    Para el tratamiento del cáncer, la radioterapia es la modalidad no quirúrgica más importante dentro de las terapéuticas oncológicas. Si bien la eficacia de este tratamiento en la erradicación del tumor depende de la dosis total de radiación impartida, la tolerancia del tejido sano es el factor que limita el tratamiento. Al respecto, se ha observado que algunos pacientes desarrollan efectos secundarios agudos en estos tejidos. Debido a que la radioterapia ejerce efectos citotóxicos a través de...

    2006-09-01

    Full Text Available This paper describes the biological mechanisms of normal tissue reactions after radiation therapy, with reference to conventional treatments, new treatments, and treatments in developing countries. It also describes biological reasons for the latency period before tissue complications arise, the relationship of dose to incidence, the effect of increasing the size of the irradiated volume, early and late tissue reactions, effects of changes in dose fractionation and dose rate, and combined chemotherapy and radiotherapy responses. Examples are given of increases in knowledge of clinical radiobiology from trials of new protocols. Potential modification to treatments include the use of biological response modifiers. The introduction of "response prediction" modifications to treatments might also be available in the near future. Finally, the paper points out that in some radiotherapy centers, the biologically-effective doses prescribed for combined brachytherapy and teletherapy treatment of cervix cancer are lower than those prescribed in other centers. This issue needs to be addressed further. The wealth of preclinical and clinical data has led to a much greater understanding of the biological basis to radiotherapy. This understanding has underpinned a variety of new approaches in radiotherapy, including both physical and biological strategies. There is also the important issue of treatment of a large number of cancers in developing countries, for which efficacious resource-sparing protocols are being continuously developed. A unified scoring system should be widely accepted as the new standard in reporting the adverse effects of radiation therapy. Likewise, late toxicity should be reported on an actuarial basis as a mandatory endpoint.En este artículo se describen los mecanismos biológicos que intervienen en las reacciones provocadas por la radioterapia, tanto con tratamientos convencionales como con los más nuevos, y los aplicados en países en

    Full Text Available É sabido que o envelhecimento da população do mundo durante o século XX e no início deste novo século constitui um desafio de primeira ordem para as nações, especialmente no campo socioeconômico. Um aspecto importante do envelhecimento populacional global é que, para grupos de idade mais avançada, a prevalência das doenças degenerativas também é maior, incluindo as doenças malignas. No universo de pacientes portadores de câncer, por outro lado, metade destes receberá radioterapia em algum momento de sua doença e suas características individuais podem influenciar, de alguma forma, o prognóstico, a indicação e as doses diárias de prescrição dos tratamentos. Neste contexto, a assistência à saúde do idoso portador de câncer deve ser vista como um importante desafio, principalmente devido a dois fatores: uma maior procura de tratamentos, em termos quantitativos, e características fisiológicas peculiares a esta população, que podem influenciar na tomada de decisões terapêuticas. Esta revisão propõe uma discussão sobre alguns aspectos relevantes tanto da fisiologia dos idosos, que pode influenciar o curso do tratamento irradiante, quanto de alguns avanços técnicos da radioterapia, que podem, por sua vez, beneficiar estes pacientes, oferecendo menor toxicidade e maior eficiência e rapidez, por exemplo.It is known that the aging of the world population during the twentieth century and the beginning of this new century is a first-order challenge for nations, especially in the socio-economic field. An important aspect of the aging of global population is that, for older age groups, the prevalence of degenerative diseases is also higher, including malignancies. On the other hand, among the population of patients with cancer, half of these patients will receive radiation therapy at some point in their illness and their individual characteristics can somehow influence the prognosis, the indication and daily doses of

    2003-04-30

    The aim of this paper is to evaluate whether the UK regional electricity companies (RECs) has used total quality management (TQM) as a &apos;'push'&apos; or as a &apos;'pull'&apos; change methodology. &apos;'Push'&apos; is the operational improvement role of TQM; &apos;'pull'&apos; is the strategic or direction giving, improvement role of TQM. Following the onset of privatisation in 1990 there has been evidence of the RECs adopting TQM in both &apos;'push'&apos; and &apos;'pull'&apos; methodologies with varying degrees of success. An evaluation of the change processes involved will enable improved change models to be developed leading to increased business effectiveness in this 30 billion pounds sterling industry. Other possible benefits include the possible generalisations to other utilities such as water, roads, gas and telecoms. The research methodology includes a comparative case study analysis of five RECs, which have used TQM as their overarching approach to change. One of the cases is analysed to a more in-depth level based on the multiple case findings. The findings indicate that the &apos;'push-pull'&apos; analysis enables the full range of TQM activities to be evaluated in the RECs studied. Overall, there is a need to have a balanced portfolio of operational or &apos;'push'&apos;-based TQM activity that is driven by strategic or &apos;'pull'&apos; based TQM planning and activity.

    A detailed retrospective analysis of 260 patients with T 1 NO MO vocal cord carcinoma treated at "Instituto de Oncologia y Radioterapia de Mar del Plata" from 1967 to 1985 was performed. The majority of the patients were in the age range of 50 to 79 years, and 79% were males. The overall observed three year tumor free survival was 85.3%. When survival rate was adjusted for intercurrent disease and second primary tumor death, the 3 year tumor free survival was 92%. Sixty two percent of the patients (17/27) undergoing surgical salvage for recurrence, were controlled. Second primary tumors were seen in 18 patients (6.9%). It is emphasized the importance of close follow up to diagnose as early as possible both the vocal cord recurrence and the second primary tumors.

    High-energy radiography is used traditionally for the detection of defects in the thick-walled, bulky components. It is also used for testing the integrity of components for civil and security related applications (containers). The combination of high-energy emitters with digital detector arrays or line cameras allows test procedures in a shorter time compared to film or higher contrast sensitivity. The high-energy X-ray laboratory HEXYLab BAM is a joint laboratory in which future users, manufacturers and scientists can initiate and develop joint development projects. The new universal manipulation system HEXYTech forms the engineering and technical base for the most diverse requirements in HEXYLab (High Energy X-raY Lab.). With a total of 13 rotary and linear axes the diverse trajectories for tube, object and detector can be programmed. So large objects with complex geometries can be examined. 2D and 3D images can be measured by simple radiography, and laminography and computed tomography. The general rules for the application of high energy radiography with digital detectors (imaging plates, Digital detector arrays) were determined within the framework of the European project &apos;'HEDRad'&apos; (High Energy Digital Radiography) and included in the standard DIN EN ISO 17636-2. This article gives an overview of the testing technology and presents the possible applications on the basis of images and experiments. (PowerPoint slides).

The anthropological interpretative approach and the ethnographic method guided the investigation. Ten patients took part in the study. They were of both genders, within the age range from 34 to 80 years old and monitored during radiotherapy treatment. Data were collected through semi-structured interviews, participative observation and medical records. The analysis of the respondents' statements allowed for the identification of the units of meaning: The encounter with radiotherapy, the body as a vehicle for radiotherapy action and alternative healthcare practices that relieved the effects of the treatment. We understand that the oncologic radiotherapy experience meant the need to submit to a therapy with a characteristic of a poison-drug, which causes fear, but was necessary, whether the goal was cure or even cancer survival.El estudio tuvo como objetivo comprender la experiencia de los pacientes sometidos a radioterapia oncológica.

    Oil producers are increasingly under pressure to produce their product in an environmentally sound manner. Releases to the environment are undesirable and, where permitted to make such releases, oil producers should minimise their environmental impact. The bulk of treatment chemicals designed to improve separation and provide clean water for disposal can themselves be harmful to the environment and must conform to very stringent rules to be considered environmentally acceptable, or &apos;'green'&apos;. Here we present data on the development of a green demulsifier for Statoil&apos;s Gullfaks &apos;'A'&apos; platform, which not only meets the very stringent regulations but also exhibits a significant improvement in product performance. While the&apos;&apos;bottle test&apos;&apos; remains the industry standard method for selecting demulsifiers, in recent years the &apos;&apos;mini trial&apos;&apos; method for product selection has gained favour. We describe using a combination of both methods for the development of the novel demulsifier technology described here. (Author) (tk)

  11. The &apos;'invisible'&apos; radioactive scale

    Energy Technology Data Exchange (ETDEWEB)

    1999-04-01

    Production and up-concentration of naturally occurring radioactive material (NORM) in the petroleum industry has attracted steadily increasing attention during the last 15 years. Most production engineers today associate this radioactivity with precipitates (scales) and sludges in production tubing, pumps, valves, separators, settling tanks etc., wherever water is being transported or treated. {sup 226}Ra and {sup 228}Ra are the most well known radioactive constituents in scale. Surprisingly little known is the radioactive contamination by {sup 210}Pb and progeny {sup 210}Bi and {sup 210}Po. These are found in combination with {sup 226}Ra in ordinary scale, often in layer of non-radioactive metallic lead in water transportation systems, but also in pure gas and condensate handling systems &apos;'unsupported'&apos; by {sup 226}Ra, but due to transportation and decay of the noble gas {sup 222}Rn in NG/LNG. This latter contamination may be rather thin, in some cases virtually invisible. When, in addition, the radiation energies are low enough for not being detectable on the equipment outer surface, its existence has for most people in the industry been a secret. The report discusses transportation and deposition mechanisms, detection methods and provides some examples of measured results from the North Sea on equipment sent for maintenance. It is concluded that a regular measurement program for this type of contamination should be mandatory under all dismantling processes of transportation and fluid handling equipment for fluids and gases offshore and onshore.

    Full Text Available OBJETIVO: Reportar os resultados preliminares do tratamento do carcinoma do canal anal com radioterapia e quimioterapia concomitantes. MÉTODOS: De janeiro de 1992 a maio de 1998, foram tratados 24 pacientes com diagnóstico histológico de carcinoma do canal anal, sendo 18 pacientes do sexo feminino e seis do sexo masculino (3:1. A idade dos mesmos variou de 35 a 74 anos e a média foi de 59 anos. A distribuição do número de pacientes por estádio clínico foi: I - 1, II - 13, III - 9 e IV - 1. A radioterapia foi realizada com dose de 45 Gy na pelve no Acelerador Linear de 4 MV, seguida de complementação de dose no canal anal até 55 Gy através de campo direto no cobalto. A quimioterapia foi realizada com 5-FU (1.000mg/m² em infusão contínua e mitomicina C (10mg/m² em bólus durante os cinco primeiros e os cinco últimos dias da radioterapia. RESULTADOS: O seguimento médio foi de 34 meses. Resposta completa ao tratamento foi obtida em 23 (95,8% pacientes. Quatorze (58,3% estão vivos sem doença, três (12% vivos com doença, cinco (20,8% mortos pelo câncer e um (4,2% morreu sem câncer. Recidivas locais ocorreram em cinco (20,8% pacientes e metástase a distância em quatro (16,6%. A função esfincteriana foi preservada em 18 (75% pacientes. Complicações agudas e crônicas foram observadas em 19 (79,2% e em nove (37,5% pacientes respectivamente. CONCLUSÕES: O tratamento foi efetivo em termos de controle local e preservação esfincteriana, porém com toxicidade aguda e tardia elevadas. Diminuição da dose de radioterapia em toda pelve representa uma estratégia razoável para diminuir os efeitos colaterais agudos e crônicos. Um maior número de pacientes e seguimento mais longo trarão mais informações sobre esta abordagem terapêutica.

    Full Text Available Summary Background Narcolepsy is a common neuropsychiatric disorder characterized by increased daytime sleepiness, cataplexy and hypnagogic hallucinations. Deficiency of the hypocretin neurotransmitter system was shown to be involved in the pathogenesis of narcolepsy in animals and men. There are several hints that neurodegeneration of hypocretin producing neurons in the hypothalamus is the pathological correlate of narcolepsy. The ApoE4 allele is a major contributing factor to early-onset neuronal degeneration in Alzheimer disease and other neurodegenerative diseases as well. Methods To clarify whether the ApoE4 phenotype predisposes to narcolepsy or associates with an earlier disease onset, we have genotyped the ApoE gene in 103 patients with narcolepsy and 101 healthy controls. Results The frequency of the E4 allele of the ApoE gene was 11% in the patient and 15% in the control groups. Furthermore, the mean age of onset did not differ between the ApoE4+ and ApoE4- patient groups. Conclusion Our results exclude the ApoE4 allele as a major risk factor for narcolepsy.

    Full Text Available Radiotherapy is frequently employed for the treatment of head and neck squamous cell carcinoma. Among the side effects, xerostomia is one of the most important. With the objective of evaluating the role of radiotherapy in salivary flow, we performed three salivary sample collections: at the beginning of, during, and immediately after radiotherapy. The results showed that the salivary flow values of the first collection were very similar to those of the control group. However, during treatment, there was a significant decrease of the salivary flow (p = 0.0008, which continued low immediately after radiotherapy (p = 0.0009. Our study showed that radiotherapy leads to an important reduction of salivary flow during and after radiotherapy.A radioterapia é um tratamento comumente empregado em pacientes portadores de carcinomas espinocelulares em cabeça e pescoço. Entre os efeitos colaterais locais, a xerostomia é um dos mais importantes. Com o objetivo de avaliar o efeito da radioterapia sobre o fluxo salivar, foram feitas 3 coletas salivares: no início, em um período intermediário e posteriormente ao tratamento radioterápico. Os resultados obtidos demonstraram médias de fluxo salivar semelhantes entre a coleta inicial e o grupo controle. Com o decorrer da radioterapia, houve diminuição significativa do fluxo salivar na coleta intermediária (p = 0,0008, que se manteve após o término da radioterapia (p = 0,0009. Nosso estudo enfatiza que há redução significativa do fluxo salivar durante e após a radioterapia.

    There are plans for Swiss pumped hydrostorage systems to absorb large quantities of excess electricity from European wind and solar power generation. Model-based analyses have shown however that &apos;'Europe&apos;s battery&apos;&apos;, as Switzerland would like to see itself, will not be needed until the middle of this century. Even if all extension projects currently in progress should be completed, Switzerland will not have sufficient pump capacity or import capacity to absorb large amounts of excess electricity. Furthermore, the primary means of making storage capacity available for import electricity would be to reduce reservoir power plant capacity. In view of all this Switzerland&apos;s hopes for a role as a major European electricity storage provider appear somewhat exaggerated even in the long-term perspective.

    Full Text Available Objectives: we analyzed long-term morbidity and bowel function alteration after postoperative radiotherapy for rectal cancer following resection with anastomosis. Patients and methods: thirty-seven patients who underwent surgery with intention to cure and a minimal follow-up period of 3 years were included. These patients were divided into two groups: in the first group, 14 patients received postoperative chemo-radiotherapy, 5-fluorouracil plus folinic acid, and 45 Gy plus 5 Gy boost. In the second group, there were 23 patients regarded as controls. We designed a questionnaire about their bowel function and analyzed the morbidity detected in their follow-up. Results: the group that was treated with postoperative chemo-radiotherapy had more daily bowel movements (p = 0.03 and night-time movements (p = 0.04; incontinence (69.2 versus 17.4% in the control group; p = 0.002, and perianal skin irritation (p = 0.04 versus the control group. Although without meaningful differences, the group under treatment wore a pad more often, had more defecatory urgency, could distinguish worse gas from stool, and needed more frequently antidiarrheal measures. Major complications were present in 28.6% of the under-treatment group: three intestinal resections were performed due to actinic stenosis; one patient had a residual stercoral fistula; another had several occlusive crises solved with medical treatment. Conclusions: postoperative chemo-radiotherapy had a high morbidity rate, which determined a significant alteration in quality of life. Accuracy in indication is therefore necessary, as well as a consideration of other alternatives for treatment, such as preoperative chemo-radiotherapy and total mesorectal excision.Objetivos: analizar la morbilidad y alteración del funcionalismo rectal a largo plazo de la radioterapia postoperatoria tras resección con anastomosis en el cáncer de recto.

    The concept &apos;'environment'&apos; is of considerable importance in present-day engineering thermodynamics. Introduction of this concept in operation brings not only simplification of the methods of solving classical thermodynamic problems, but also gives the exergy method which forms the major new part of thermodynamics, including some parts of biology, economics and other fields of science. But practice shows that it is necessary to define the concept &apos;'environment'&apos; more precisely in some cases. (author)

    When regulators put forward new economic or regulatory policies, there is a need to compare the costs and benefits of these new policies to existing policies and other alternatives to determine which policy is most cost-effective. For command and control policies, it is quite difficult to compute costs, but for more market-based policies, economists have had a great deal of success employing general equilibrium models to assess a policy&apos;s costs. Not all cost measures, however, arrive at the same ranking. Furthermore, cost measures can produce contradictory results for a specific policy. These problems make it difficult for a policy-maker to determine the best policy. For a cost measures to be of value, one would like to be confident of two things. First one wants to be sure whether the policy is a winner or loser. Second, one wants to be confident that a measure produces the correct policy ranking. That is, one wants to have confidence in a policy measure&apos;s ability to correctly rank policies from most beneficial to most harmful. This paper analyzes empirically these two properties of different costs measures as they pertain to assessing the costs of the carbon abatement policies, especially the Kyoto Protocol, under alternative assumptions about implementation.

    Objective. To report the sign of &apos;&apos;spinolaminar breach&apos;&apos; and its likely importance in fractures of the cervical spinous processes.Design. Six cases of spinous process fractures demonstrating disruption of the spinolaminar line or &apos;&apos;spinolaminar breach&apos;&apos; were analyzed. Lateral and anteroposterior radiographs (n=6), CT scans (n=3) and MRI scans (n=1) were reviewed together by the authors, with consensus being reached as to the radiographic findings. Clinical records were also reviewed.Results. The levels of injury were C6 (n=5) and C5 (n=2). Injuries were associated with delayed anterior subluxation (n=4) and neurological deficit (n=2). Five patients were male and one was female with a mean age of 31 years (range 8-59 years). Injuries resulted from motor vehicle accidents (n=4), a motor cycle accident (n=1) and a fall (n=1).Conclusion. &apos;&apos;Spinolaminar breach&apos;&apos;, or disruption of the spinolaminar line, indicates a complex spinous process fracture with extension into the lamina and spinal canal. Spinous process fractures with spinolaminar breach may have associated posterior ligamentous injury with potential for delayed instability and neurological deficit. It is important that radiologists and physicians caring for the trauma patient be aware of this sign in order to avoid misdiagnosis as a &apos;&apos;clay shoveler&apos;s fracture&apos;&apos;, which can lead to adverse outcome.

    Full Text Available Avaliou-se a eficácia da radioterapia no tratamento de felinos portadores de carcinoma de células escamosas cutâneo avançado. Um protocolo de fracionamento padrão de radioterapia foi aplicado em seis gatos portadores de uma ou mais lesões cutâneas de carcinoma de células escamosas, em um total de sete lesões neoplásicas, confirmadas por meio de análise histológica. Uma lesão foi classificada como T2 e seis como T4, segundo o sistema de estadiamento da Organização Mundial de Saúde para tumores epidermais de felinos. Os animais foram submetidos a doze frações radioterápicas de 4 Gy, realizadas três vezes por semana, utilizando-se um equipamento de ortovoltagem. Utilizaram-se energia de 120 Kv, 15mA e filtro 2mm de alumínio, o cone usado foi de 6x8cm, e a distância foco-pele foi de 30cm. As lesões foram acompanhadas durante todo o tratamento radioterápico e 30 e 60 dias após o seu término. Neste estudo, 87% das lesões resultaram em remissão completa, e 13%, em remissão parcial. Os efeitos colaterais do tratamento radioterápico, de acordo com a tabela de critérios de toxicidade aguda da Veterinary Radiation Therapy Oncology Group, foram leves e reversíveis em todos os casos, e incluíram eritema cutâneo, epilação e rinite. Considerou-se a radioterapia segura para felinos com carcinoma de células escamosas cutâneo, levando a efeitos colaterais leves, e pode representar uma boa opção terapêutica.

    Full Text Available TEMA: cirurgia, radioterapia e quimioterapia são as modalidades terapêuticas usadas no tratamento de câncer bucal. Podem ser usadas isoladas ou conjuntamente. Radiação ionizante causa lesões nos tecidos normais localizados no campo de radiação. Isto se torna particularmente evidente nas regiões de cabeça, uma área complexa composta de várias estruturas diferentes que respondem diferentemente à radiação. As seqüelas orais resultantes podem causar problemas substanciais durante e depois da terapia de radiação e são os maiores fatores de determinação na qualidade de vida dos pacientes. Dentre as complicações da radioterapia estão a xerostomia, osteorradionecrose, mucosite e candidose. OBJETIVO: apresentar aos profissionais de saúde uma reflexão sobre as questões pertinentes às sequelas bucais da radioterapia de cabeça e pescoço. CONCLUSÃO: o acompanhamento odontológico sistemático pode minimizar os efeitos da radiação sobre os tecidos da cavidade bucal.BACKGROUND: surgery, radiotherapy and chemotherapy are therapeutic modalities used in the treatment of oral cancer. They can be used separately or in combination. Ionizing irradiation causes damage to normal tissues located at the radiation field. This becomes particularly evident in the head and neck region, a complex area composed of several dissimilar structures that respond differently to radiation. The resulting oral sequelae may cause substantial problems during and after radiation therapy and are major factors in determining the patient's quality of life. Xerostomia, osteoradionecrosis, mucositis and candidosis are some of radiotherapy's complications. PURPOSE: introduce health professionals to reflect on issues relevant to oral sequelae of head and neck radiotherapy. CONCLUSION: regular dental follow-up may reduce the effects of radiation in the tissues of the oral cavity.

    This study aims to identify the premature synostosis of &apos;'major'&apos; and &apos;'minor'&apos; sutures of the four &apos;&apos;sutural arches&apos;&apos; of the skull and to perform a morphometric analysis in children with syndromic craniosynostosis in order to evaluate changes in the skull base linked with premature suture synostosis. We reviewed multiplanar high-resolution CT images, implemented with 3D reconstructions, from 18 patients with complex syndromic craniosynostosis and compared them with 18 age-matched healthy subjects. We assessed the calvarial sutures and their extension to the skull base, and then we correlated specific types of synostosis with the size, shape and symmetry of the cranial fossae. We found a marked asymmetry of the skull base growth in all patients. The synostotic involvement around the coronal ring caused a reduction in the growth of the anterior and middle fossae. The size of the posterior cranial fossa was related not only to &apos;'major'&apos; but also to &apos;'minor'&apos; suture synostosis of the lambdoid and parieto-squamosal arches. Changes in the skull base and craniofacial axis symmetry are due to structural and functional relationships between &apos;'major'&apos; and &apos;'minor'&apos; skull sutures, suggesting a structural and functional relationship between the neurocranium and basicranium. The early recognition of prematurely closed skull base sutures may help clinicians and neurosurgeons to establish correct therapeutic approaches. (orig.)

    Full Text Available INTRODUCCIÓN. El angiofibroma juvenil de nasofaringe es un tumor benigno infrecuente, compuesto de tejido conectivo fibroso y abundancia de espacios vasculares revestidos de endotelio. Es casi exclusivo del sexo masculino y de la adolescencia. El tratamiento de elección es la exéresis, sin descartar otras posibilidades como la radioterapia. El objetivo del presente estudio fue presentar los resultados de esta última como opción terapéutica. MÉTODOS. Se estudió una serie de 11 pacientes, todos del sexo masculino, con edades entre 9 y 16 años, que fueron tratados en el Instituto Nacional de Oncología y Radiobiología de La Habana entre 1990 y 2005. Los pacientes fueron seguidos entre 48 y 306 meses. La radioterapia aplicada consistió en la irradiación de todo el volumen tumoral, con un margen de seguridad, en dosis de 40 a 60 Gy, con 1,8 Gy por sesión. Asociado a la radioterapia se utilizó interferón, durante y después de la irradiación, y poliquimioterapia en 1 paciente. RESULTADOS. Se obtuvo la remisión completa mantenida, sin recidivas, en 10 pacientes. No hubo pacientes con un segundo tumor. Presentaron complicaciones tempranas todos los pacientes, y tardías, solo algunos. Entre las complicaciones tempranas se halló radiomucositis y conjuntivis radiógena, y las más graves de las tardías fueron la pérdida permanente de las pestañas del párpado inferior en un caso y cataratas radiógenas en 4 pacientes. CONCLUSIONES. La radioterapia es un tratamiento que conserva su utilidad e indicaciones específicas.INTRODUCTION: The nasopharyngeal juvenile angiofribroma is a uncommon benign tumor composed of fibrous connective tissue and many vascular spaces covered by endothelium. It is almost exclusive of male sex and of adolescents. Choice treatment is the exeresis without obviate other possibilities as the radiotherapy.

    A acurácia e precisão exigida nas novas técnicas radioterápicas é bastante elevada, como no caso da Radioterapia com Intensidade Modulada (IMRT). Desta forma, o tamanho dos dosímetros a serem utilizados nas medidas experimentais é um fator crítico. Além disso, a ausência de equilíbrio eletrônico lateral e a existência de intensos gradientes de dose no campo apresentam um desafio na determinação da dose administrada no tumor. Alguns dos dosímetro utilizados atualmente não apresentam resolução ...

    Full Text Available La experiencia acumulada en más de un siglo de práctica de radioterapia ha puesto de manifiesto su importancia no solamente para la atención paliativa de una parte de los casos de cáncer, sino principalmente para la curación de una proporción aun mayor de esos pacientes. Teniendo en cuenta la evolución tecnológica, el acceso cada vez mayor que tienen los países en desarrollo a estos métodos y la cobertura actual en América Latina, los esfuerzos en esta área se deben dirigir a mejorar la calidad de los servicios y de los centros de radioterapia ya instalados. Para ello se debe completar su parque tecnológico, ampliar los servicios que prestan y cumplir los requerimientos mínimos de calidad establecidos para instalaciones del nivel 2. Cada centro debe estar en condiciones de realizar todas las etapas del proceso de radioterapia -desde la simulación hasta la verificación del tratamiento y el seguimiento de los pacientes- con una calidad adecuada (nivel 2. Para ello deben contar con la tecnología necesaria y con el personal debidamente capacitado. Los esfuerzos cooperativos en la Región deben tener también como prioridad contribuir a que los países adopten guías nacionales de tratamiento que contemplen todas las etapas del proceso de radioterapia y fomentar la puesta en marcha de programas validados de garantía de la calidad.The cumulative experience gathered over more than a century of practice of radiotherapy has demonstrated the latter's importance not only for the palliative treatment of a fraction of cancer cases, but mainly for the curative treatment of an even greater proportion of such cases. In light of the changes in technology, the ever-increasing access developing countries to such technology, and its current coverage in Latin America, any efforts in this area should be aimed at improving the quality of the radiotherapy services and centers that are already in place.

No exame clínico, foi observada uma massa ulcerada no terço médio da língua medindo 3,5 x 4,0cm. A histopatologia e a imuno-histoquímica levaram ao diagnóstico de um mastocitoma de alto grau. O tratamento cirúrgico (glossectomia parcial foi declinado pelo proprietário, sendo a radioterapia indicada em seu lugar. O protocolo radioterápico empregado foi 15 frações de 300cGy, realizadas cinco vezes por semana. O equipamento utilizado foi de ortovoltagem. A lesão neoplásica apresentou remissão clínica completa a partir da quarta sessão radioterápica. O único efeito colateral observado foi mucosite leve na região irradiada, que, entretanto, não levou a sintomas clínicos. A quimioterapia sistêmica consistiu de vimblastina e lomustina, alternadas a cada 14 dias, durante quatro meses. Até o momento (22 meses após o tratamento, não há evidências de recidiva local ou metástases do mastocitoma. A associação da radioterapia e da quimioterapia pode ser considerada uma alternativa terapêutica nos casos de mastocitomas irressecáveis, já que, neste caso, levou à remissão completa e duradoura de um tumor agressivo, com ótima tolerância do paciente ao tratamento e posterior qualidade de vida.

    With a population of over 1.3 billion people, demand for renewable energy is expected to grow to a USD $12 billion market in the near term. Under Renewable Energy Law (REL) in February 2005 in the People&apos;s Republic of China (PRC) passed by the National Congress, renewable energy projects will be able to receive a range of financial incentives starting in 2006, which will more than double the PRC current renewable energy generation from 7% to 15% by 2020. Most of the increase will be in hydroelectric generated power. Nonetheless, the nation and especially the provinces are moving rapidly to develop a wide range of renewable energy generation including solar, wind, geothermal and run of the river. Because China practices &apos;&apos;social capitalism&apos;&apos; as expressed in it&apos;s recurrent Five Year National Plans since 1999, the national government and all the provinces have programs, unlike many western and industrialized nations, to &apos;'plan'&apos; and provide for infrastructures. This paper concerns only the energy infrastructure sector and renewable energy generation in particular. The planning process includes financial incentives and investments which are a major part of the Chinese law focused on &apos;&apos;encouraging foreign investment industries&apos;&apos;. The key part of the law is to guarantee long-term power purchase agreements with state owned and controlled &apos;'utilities'&apos;. In short, China may have gotten the economics of the energy sector correct in its concern for planning and finance. The paper develops these energy infrastructure ideas along with the legal and financial requirements as &apos;'lessons'&apos; learned from the USA and especially California. These lessons now apply to China and allow it to learn from the American mistakes. Empirical data will be drawn from work done in China that examine the renewable energy generation and infrastructures and hence allow the RPC and its

    Full Text Available O câncer de mama é a forma de câncer que mais causa mortes entre mulheres no Brasil. O tratamento consiste em intervenção cirúrgica, quimioterapia, hormonioterapia e radioterapia, esta última responsável por uma significativa diminuição na taxa de recorrência local do câncer, mas que pode afetar a função pulmonar. O objetivo deste estudo foi detectar alterações pulmonares funcionais decorrentes da radioterapia no tratamento do câncer de mama. Participaram do estudo 10 mulheres submetidas a tratamento do câncer de mama, avaliadas quanto à função pulmonar antes e após a radioterapia. Foram mensuradas capacidade inspiratória e capacidade vital forçada, por espirômetro de incentivo, e pressões inspiratória e expiratória máximas, por manovacuômetro. Embora tenha havido redução, em vários casos, dos valores medidos antes e depois da radioterapia, não foi encontrada diferença estatisticamente significativa. Nas pacientes avaliadas, pois, a radioterapia não parece ter prejudicado a função pulmonar.Breast cancer is the cancer that most causes death among women in Brazil. The treatment consists in surgery, chemotherapy, hormontherapy, and radiotherapy, the latter being responsible for important decrease in recurrence rates, though it may affect pulmonary function. The aim of this study was to detect lung function changes due to radiotherapy in breast cancer treatment. Ten women who were undergoing breast cancer treatment were assessed as to pulmonary function before and after radiotherapy. Measurements taken were inspiratory capacity and forced vital capacity, by means of incentive spirometer, and maximum inspiratory and expiratory pressures, using a pressure meter. Though in many cases measures found after radiotherapy were lower, no significant difference could be found. Thus radiotherapy did not seem to affect lung function in the assessed sample of women with breast cancer.

    This is the fifth Village Power workshop sponsored by NREL. We have held these meetings every year since 1993, to focus, challenge, and provide a forum for interaction among practitioners working in the field of using renewable energy technologies as an economically viable pathway to electrification of rural populations throughout the world. Starting with a small group of 30 colleagues in 1993, this &apos;'workshop'&apos; has doubled in size every year. When the NREL staff was planning for this meeting, they were hoping for something around 400 participants. We are now looking at over 500, and we apologize for the somewhat cramped accommodations. This overwhelming response, however, shows that the use of renewable energy to solve some of the world&apos;s serious problems is coming of age. This meeting, this &apos;'conference'&apos; (it&apos;s clearly no longer a workshop) marks a transition. A transition from the viewpoint that renewables are, and forever will be a technology of the future; to the reality that renewables have come of age. We have technologies available today, at today&apos;s prices, that can make a substantive contribution to the pressing needs of environmentally sustainable development in the world. This is a collection of all the papers presented at the Village Power &apos;98 conference.

    A series of tests were performed at Oak Ridge National Laboratory (ORNL) to evaluate and characterize the radiological response of a &apos;'Cricket'&apos; radiation detection system. The &apos;'Cricket'&apos; is manufactured by RAD/COMM Systems Corp., which is located in Ontario, Canada. The system is designed to detect radioactive material that may be contained in scrap metal. The Cricket&apos;s detection unit is mounted to the base of a grappler and monitors material, while the grappler&apos;s tines hold the material. It can also be used to scan material in an attempt to isolate radioactive material if an alarm occurs. Testing was performed at the Environmental Effects Laboratory located at ORNL and operated by the Engineering Science and Technology Division. Tests performed included the following: (1) Background stability, (2) Energy response using {sup 241}Am, {sup 137}Cs, and {sup 60}Co, (3) Surface uniformity, (4) Angular dependence, (5) Alarm actuation, (6) Alarm threshold vs. background, (7) Shielding, (8) Response to {sup 235}U, (9) Response to neutrons using unmoderated {sup 252}Cf, and (10) Response to transient radiation.

The Coal Question: an Inquiry Concerning the Progress of the Nation, and the Probable Exhaustion of our Coal-mines. 3rd edition 1905, Ed. A.W. Flux. Augustus M. Kelley, New York.] maintained that technological efficiency gains-specifically the more &apos;economical&apos; use of coal in engines doing mechanical work-actually increased the overall consumption of coal, iron, and other resources, rather than &apos;saving&apos; them, as many claimed. Twentieth-century economic growth theory also sees technological change as the main cause of increased production and consumption. In contrast, some ecologically-oriented economists and practically all governments, green political parties and NGOs believe that efficiency gains lower consumption and negative environmental impact. Others doubt this &apos;efficiency strategy&apos; towards sustainability, holding that efficiency gains &apos;rebound&apos; or even &apos;backfire&apos; in pursuing this goal, causing higher production and consumption. Because many environmental problems demand rapid and clear policy recommendations, this issue deserves high priority in ecological economics. If Jevons is right, efficiency policies are counter-productive, and business-as-usual efficiency gains must be compensated for with physical caps like quotas or rationing.

    To evaluate the association between vertebral &apos;&apos;end plate sclerosis&apos;&apos; and neck pain. A retrospective study was carried out of lateral cervical spine radiographs with a Picture Archive and Communication System (PACS). Two hundred patients&apos; files were randomly assessed, comprising four equal groups, A to D. The mean ages of the patients were 62{+-}7.4 years, 61{+-}7.5 years, 40{+-}5.6 years and 23{+-}5.6 years respectively. In group A, all patients had symptoms of neck pain and a radiographic diagnosis of &apos;&apos;end plate sclerosis&apos;&apos; of the cervical spine. In groups B to D, asymptomatic patients were recruited and their age groups were 50-69, 30-49 and 10-29 years respectively. Using the PACS, the radiographic density and the sagittal diameter, thickness and area of the end plates at the C5 level were measured. Results and conclusions: No significant differences were found in the radiographic density of the end plates either between the symptomatic and asymptomatic groups (groups A and B), or between different age groups (groups B, C and D). A significant increase in end plate area and thickness was found, however, in both group B (P<0.005) and group C (P<0.01) in comparison with group D. This indicates that the extent of end plate sclerosis increases with age. Our results suggest that the radiographic density of cervical vertebral end plates correlates neither with neck pain nor with increasing age. The radiological sign of &apos;&apos;end plate sclerosis&apos;&apos; may be over-reported, further limiting its value in the assessment of patients with cervical spondylosis. (orig.)

    A descriptive study of breast and cervix cancer was performed in patients who have received treatment linear accelerator, during the period 2000 - 2001 in the Centro Medico de Radioterapia Irazu. The survival of the patients was assessed to five years (2006). One proposal called database is the product of analysis performed and consistent with the objectives set. The idea to develop the database of these features in the medical center, arises because the Centre was at that time with the only linear accelerator in the country and also all the necessary information of patients was easily accessible. A population of 438 records, with a common pathology was analyzed under the following variables: type of cancer, identification of anatomic region, province, age, sex, type of radiation, number of sessions, referral hospital, physician, physician referral. This work is relevant, because breast and cervical cancers have been a major cause of mortality, ranked among the five most common malignancies in women. From there to have adequate information systems, has led policy makers and health professionals to have a better outlook for their level of management. (author) [es

    Introduction: The standard treatment for patients with high risk prostate cancer is the combined use of radiation therapy (RT ) and hormone therapy (HT). In regards to patients stratified as intermediate risk, the use of HT associated with RT remains controversial, and its use should be carefully planned and based on available evidence. Objective: To critically assess results of randomized studies published in the literature that associated the use of HT of short duration with an average period of 6 months with RT in the treatment of patients with localized prostate cancer classified as intermediate risk. Method: Only randomized studies comparing these treatments were eligible for this review. A structured search through &apos;PubMed&apos; was carried out using the terms &apos;androgen suppression therapy&apos;, &apos;radiotherapy&apos;, &apos;randomized trials&apos;, &apos;phase 3 trials&apos;, &apos;prostate cancer&apos; and &apos;intermediate risk&apos;. Results: Four randomized studies comparing RT alone to RT plus short course HT were found and selected. The majority of the trials had a mixed population of intermediate and high risk disease and did not include patients with only intermediate risk. Despite that, there appears to be a significant benefit for the combined approach regarding disease-free survival, biochemical free survival and overall survival. Conclusion: The randomized studies published so far suggest improved outcomes for the group of patients receiving RT and short course HT. Data from randomized trials comparing RT alone to RT and short course HT in patients with intermediate risk only are forthcoming. (author)

    Assess extensor carpi ulnaris (ECU) tendon position in the ulnar groove, determine the frequency of tendon &apos;'dislocation'&apos; with the forearm prone, neutral, and supine, and determine if an association exists between ulnar groove morphology and tendon position in asymptomatic volunteers. Axial proton density-weighted MR was performed through the distal radioulnar joint with the forearm prone, neutral, and supine in 38 asymptomatic wrists. The percentage of the tendon located beyond the ulnar-most border of the ulnar groove was recorded. Ulnar groove depth and length was measured and ECU tendon signal was assessed. 15.8 % of tendons remained within the groove in all forearm positions. In 76.3 %, the tendon translated medially from prone to supine. The tendon &apos;'dislocated'&apos; in 0, 10.5, and 39.5 % with the forearm prone, neutral and supine, respectively. In 7.9 % prone, 5.3 % neutral, and 10.5 % supine exams, the tendon was 51-99 % beyond the ulnar border of the ulnar groove. Mean ulnar groove depth and length were 1.6 and 7.7 mm, respectively, with an overall trend towards greater degrees of tendon translation in shorter, shallower ulnar grooves. The ECU tendon shifts in a medial direction when the forearm is supine; however, tendon &apos;'dislocation'&apos; has not been previously documented in asymptomatic volunteers. The ECU tendon medially translated or frankly dislocated from the ulnar groove in the majority of our asymptomatic volunteers, particularly when the forearm is supine. Overall greater degrees of tendon translation were observed in shorter and shallower ulnar grooves. (orig.)

    Cooperation in the economic sense considers efficiency issues. Cooperation in the political sense, like the Kyoto Protocol, considers other issues like equity and historical responsibility. The environmental and economic impacts of the Kyoto Protocol and other scenarios are thus examined. The US pullout may then be viewed, among others, as the result of not untying &apos;economic&apos; and &apos;political&apos; cooperation; and since the Protocol will be much less effective without the US, it is shown that an external economic stimulus should and may theoretically be found for retaining their participation.

    Full text: A new energy storage system with the potential to change the way the world utilises electricity has been developed in South Australia. “ With the capability and flexibility to store energy generated by solar or wind power or capture off-peak power for later use, the ZEN Freedom Power Bank offers benefits to householders, businesses and utilities,” ZEN Energy Systems chief executive officer Richard Turner said. He recently represented Australia by invitation at the International Cleantech Forum in San Fransisco and used the spotlight to feature the technology he believes is a world-first and the &apos;holy grail&apos; of renewable energy. The system is comprised of hi-density storage lithium ion batteries linked to innovative &apos;active&apos; battery balancing and control software, allowing both &apos;on-grid&apos; and &apos;off-grid&apos; management options. The electronic software has been designed in a joint development project with ZEN sister company, US-based Greensmith Energy Management Systems. The units will be assembled in Australia for supply to the local market as well as for export. “This technology enables low cost, large format &apos;dumb&apos; lithium ion cells to perform as effectively as, or better than, high cost &apos;smart&apos; cells, virtually halving the cost of the batteries or providing twice the storage capacity for the same cost,” Turner said. “The control software then enables centralised control of large communities of systems to manage peak demand or other issues within the public power grid. The base residential/business system will be capable of managing and storing 20 kilowatt hours of energy per day, which is the daily consumption of an average Australian home. For larger properties, additional 20kWh energy storage modules can be easily added,” Turner explained. “Reliance on the public grid is greatly reduced and it provides up to 24-hour energy backup if the grid goes down.” In the future, the Power

    This agreement, discussed between the French government and Electricite de France (EdF) group, proposes some engagements for the 2001-2003 era for a better environmental integration of power transmission and distribution networks. The agreement is made of two parts: 1 - public distribution networks: realization of new workmanship (medium and low voltage power lines, new lines in dense urban areas), actions on existing workmanship (consequences of December 1999 storms, aesthetical aspects, burial of the main overhead lines in wooded areas, reinforcement of EdF&apos;s environmental commitment, remedial actions for environmental &apos;black points&apos;), general measures of implementation (increasing network safety, protection of birds fauna, coordination of works); 2 - public transportation network (RTE): development and safety improvement of the public transportation network (reinforced arrangement for the establishment of regional development schemes, development of international interconnections, safety improvement of the public transportation network, RTE&apos;s environmental plan); line projects (arrangements during projects elaboration, accompanying program); long lived RTE&apos;s commitment (environmental management and ISO-14001 certification, vigilance with respect to electromagnetic fields, R and D).

    Spontaneously, we do associate &apos;&apos;green medicine&apos;&apos; with terms like naturopathy, natural healing substances, herbal active agents, homeopathy, healthy food, preventive medicine and similar things, and finally we think of ecology. This is the focus of the following article. First of all, the following question arises: Are there any environment-friendly and cost-saving alternatives to the present medicine? There is an increasing number of environment-caused diseases. Therefore, a medicine not coping with the environment is not credible. In today&apos;s medicine, for example, there are too many persistent detergents, water-polluting disinfectants, and many disposable materials. Too much water ist consumed, whereas the use of renewable energies is only limited. And too little natural healing methods are applied in diagnostics and therapy. Presently, in Germany, 16,7 million in-patients are treated in Germany, 1,16 million out-patients have surgeries in 2166 hospitals by ca. 1,1 million medical staff. All this work needs energy and materials which bring various risks to environment and the patients. During the last two decades, however, many efforts were made in the field of environment protection in medicine. There is hardly a hospital left which has not taken measures of protecting the environment. In the branch-specific quality management system KTQ (=cooperation for transparency and quality in the health system). environment protection measures are interrogated and systematically assessed.

  2. &apos;&apos;Measuring the Costs of Climate Change Policies&apos;&apos;

    Studies of the costs of climate change policies have utilized a variety of measures or metrics for summarizing costs. The leading economic models have utilized GNP, GDP, the &apos;&apos;area under a marginal cost curve,&apos;&apos; the discounted present value of consumption, and a welfare measure taken directly from the utility function of the model&apos;s representative agent (the &apos;&apos;Equivalent Variation&apos;&apos;). Even when calculated using a single model, these metrics do not necessarily give similar magnitudes of costs or even rank policies consistently. This paper discusses in non-technical terms the economic concepts lying behind each concept, the theoretical basis for expecting each measure to provide a consistent ranking of policies, and the reasons why different measures provide different rankings. It identifies a method of calculating the &apos;&apos;Equivalent Variation&apos;&apos; as theoretically superior to the other cost metrics in ranking policies. When regulators put forward new economic or regulatory policies, there is a need to compare the costs and benefits of these new policies to existing policies and other alternatives to determine which policy is most cost-effective. For command and control policies, it is quite difficult to compute costs, but for more market-based policies, economists have had a great deal of success employing general equilibrium models to assess a policy&apos;s costs. Not all cost measures, however, arrive at the same ranking. Furthermore, cost measures can produce contradictory results for a specific policy. These problems make it difficult for a policy-maker to determine the best policy. For a cost measures to be of value, one would like to be confident of two things. First one wants to be sure whether the policy is a winner or loser. Second, one wants to be confident that a measure produces the correct policy ranking. That is, one wants to have confidence in a policy measure&apos;s ability to correctly rank

    After having recalled the legal context concerning the appointment and training of a radiation protection expert (PCR for &apos;personne competente en radioprotection&apos;), the author outlines that the PCR&apos;s role has notably evolved: his function is now of primary importance in the company and his activity does not correspond to the legal framework any longer. Moreover, with the application of a European directive, some small establishments possessing ionizing radiation sources are disadvantaged, and the PCR is now facing an increasing number of missions and tasks. The author gives a list of them and assesses a needed time of 146 days per year: this means PCRs cannot have an other activity within their company

    Radiotherapy is a treatment modality largely used for head and neck malignancies. However, high doses of radiation in large areas, including the oral cavity, maxilla, mandible and salivary glands may result in several undesired reactions. Mucositis, candidosis, disgeusia, radiation caries, osteoradionecrosis, soft tissue necrosis and xerostomia are some of radiotherapy&apos;s complications.Aim: The aim of this study is to briefly review the side effects that may be seen in the oral cavity during or after radiotherapy treatment in the head and neck region.Basic Method Used: Review of relevant literature.Study Design: Literature review.Results: Radiotherapy is still associated with several side effects, significantly affecting patients quality of life.Conclusions: A multidisciplinary treatment, including physicians, dentists, speech therapists, nutritionists, and psychologists, is the best alternative to minimize, or even prevent such reactions.

    The review is devoted to various types of compounds used as agents for &apos;living&apos; radical polymerisation, such as alkoxyamines formed upon addition of the chain carrier radicals, R{sup .}, to stable nitroxyl radicals, as well as products of the addition of the radicals to transition metal complexes with different ligands, etc. In all cases, the mechanism of the action of these agents consists in their reversible dissociation ArightleftarrowsR{sup .} + X{sup .}, where X{sup .} is a stable free radical or a metal-containing complex which can accept radicals R{sup .} (R{sup .} + X{sup .}{yields}A) and thus compete with the quadratic chain termination. Particular attention is paid to the studies which allowed a quantitative formulation of the mechanism of &apos;living&apos; radical polymerisation in the form of a mathematical model suitable for predicting both the parameters of the polymerisation and the properties of the resulting polymer (molecular mass and polydispersity).

    High-energy radiography is used traditionally for the detection of defects in the thick-walled, bulky components. It is also used for testing the integrity of components for civil and security related applications (containers). The combination of high-energy emitters with digital detector arrays or line cameras allows test procedures in a shorter time compared to film or higher contrast sensitivity. The high-energy X-ray laboratory HEXYLab BAM is a joint laboratory in which future users, manufacturers and scientists can initiate and develop joint development projects. The new universal manipulation system HEXYTech forms the engineering and technical base for the most diverse requirements in HEXYLab (High Energy X-raY Lab.). With a total of 13 rotary and linear axes the diverse trajectories for tube, object and detector can be programmed. So large objects with complex geometries can be examined. 2D and 3D images can be measured by simple radiography, and laminography and computed tomography. The general rules for the application of high energy radiography with digital detectors (imaging plates, Digital detector arrays) were determined within the framework of the European project &apos;'HEDRad'&apos; (High Energy Digital Radiography) and included in the standard DIN EN ISO 17636-2. This article gives an overview of the testing technology and presents the possible applications on the basis of images and experiments. (PowerPoint slides). [de

    Runnels, Scott Robert

    2015-01-01

    From one vantage point, a shock is a continuous but drastic change in state variables that occurs over very small time and length scales. These scales and associated changes in state variables can be measured experimentally. From another vantage point, a shock is a mathematical singularity consisting of instantaneous changes in state variables. This more mathematical view gives rise to analytical solutions to idealized problems. And from a third vantage point, a shock is a structure in a hydrocode prediction. Its width depends on the simulation&apos;s grid resolution and artificial viscosity. These three vantage points can be in conflict when ideas from the associated fields are combined, and yet combining them is an important goal of an integrated modeling program. This presentation explores an example of how models for real materials in the presence of real shocks react to a hydrocode&apos;s numerical shocks of finite width. The presentation will include an introduction to plasticity for the novice, an historical view of plasticity algorithms, a demonstration of how pursuing the meaning of &apos;'shock'&apos; has resulted in hydrocode improvements, and will conclude by answering some of the questions that arise from that pursuit. After the technical part of the presentation, a few slides advertising LANL&apos;s Computational Physics Student Summer Workshop will be shown.

    The present work describes the main results of the risk evaluation for some radiotherapy treatments with lineal accelerators, cobalt 60, brachytherapy of high dose rate and brachytherapy of low dose rate that are realize in Mexico. These evaluations were carried out applying the risk matrices method with the tool computer risk evaluation system in radiotherapy, accessible for the national users through internet, and developed by the Comision Nacional de Seguridad Nuclear y Salvaguardias in Mexico, in cooperation with the Forum of Ibero-American regulators. The used methodology is based on the risk matrices method that is a mathematical tool for the risk evaluation, and it was centered in the evaluation from the risk to which are exposed the patients, the occupational exposed personnel and people in general, by the mechanical faults of the treatment equipment s, bad calibrations, human errors, or any other event initiator of accidents. The events initiators of accidents are defined as those undesirable events that can produce and administration of an excessive dose or a sub-dose of the prescribed dose by the doctor, to the planned objective volume, or undesirable dose to the patient&apos;s regions or dose to occupational exposed personnel or people in general. The barriers are the actions and systems as mechanical switches, interlocks or alarms, dedicated to avoid that these accidents take place. The evaluation analysis of the risk developed by the members of the Forum for radiotherapy facilities together with the software RESRA has demonstrated to be useful in the prevention of many possible accidents that have happened in the past in other facilities and can avoid many others in the future.

    Although the treatment results have significantly improved for several pediatric malignant neoplasms, particularly Wilms&apos;s tumor, lymphomas and leukemia, in the last decade, the prognosis of the INSS, stage 4 neuroblastoma over one year one old patients remains poor. Even for the more advanced centers, using the more aggressive treatment schedules, such as bone marrow transplantation, the probability of a 2 year progression free interval varies from 6 to 50% and at 3 to 6 years, from 13 to 54%. Thereby, at least, 46 to 94% of these patients are expected to die due to the merciless neoplasm progression. The hypothesis here to be tested is regarding the impact of the cephalic irradiation on the outcome of stage 4 patients with skull metastasis at diagnosis. The end point was to establish, under the NEURO-III-85 protocol chemotherapy schedule, the possible benefit of this radiotherapy in preventing the cephalic recurrence, and its reflex on these patients total and diseases free survival. These results disclosed that the cephalic segment irradiation may prevent recurrences at this site. Unfortunately, the decrease in the cranial recurrence frequency did not affect either the disease free interval, or the total survival. The conclusion was that cephalic irradiation have the potential of avoiding these recurrences, without modifying the final outcome. This modality of radiotherapy must be reevaluated under more effective systemic treatments. (author)

This method regards of the application of an computational algorithm to determine quantitatively the differential cross sections for the scattered particles, starting from the interaction of these antiprotons with the nuclei, what will allow in the future to draw the isodose curve for antiproton therapy, once these beams are expected to be used in cancer treatment soon. The calculation will be done through the application of the concepts of the method of intranuclear cascade, providing yield and differential cross sections of the scattered particles, present in the software MCMC. Th algorithm was developed based on Monte Carlo&apos;s method, already taking into account a validate code. The following physical quantities are presented: the yield of secondary particles, their spectral and angular distributions for these interactions. For the energy range taken into account the more important emitted particles are protons, neutrons and pions. Results shown that emitted secondary particles can modify the isodose curves, because they present high yield and energy for transverse directions. (author)

    &apos;&apos;Radiographic Testing is a NDT method to detect inherent volumetric discontinuities in materials such as castings and welds&apos;&apos; A common type of discontinuity found and most often misinterpreted and evaluated is rounded indications, whether isolated, aligned or clustered. This paper addresses the acceptance criteria of rounded indications based on various codes and standards and intends to lay at rest the confusion related to this type of discontinuity. The following are important considerations: 1. Interpretation of rounded indications based on codes and standards used in the various sectors of NDT. 2. What types of discontinuities can be regarded as rounded indications? 3. What discontinuity sizes can be regarded as relevant discontinuities? 4. What are the acceptance and rejection criteria for relevant rounded indications 5. Compiling relevant student assignments to facilitate the proper understanding of this aspect.

    &apos;&apos;Water fountains&apos;&apos; (WFs) are evolved objects showing high-velocity, collimated jets traced by water maser emission. Most of them are in the post-asymptotic giant branch (post-AGB) and they may represent one of the first manifestations of collimated mass loss in evolved stars. We present water maser, carbon monoxide, and mid-infrared spectroscopic data (obtained with the Australia Telescope Compact Array, Herschel Space Observatory, and the Very Large Telescope, respectively) toward IRAS 15103–5754, a possible planetary nebula (PN) with WF characteristics. Carbon monoxide observations show that IRAS 15103–5754 is an evolved object, while the mid-IR spectrum displays unambiguous [Ne II] emission, indicating that photoionization has started and thus, its nature as a PN is confirmed. Water maser spectra show several components spreading over a large velocity range (≅ 75 km s{sup –1}) and tracing a collimated jet. This indicates that the object is a WF, the first WF known that has already entered the PN phase. However, the spatial and kinematical distribution of the maser emission in this object are significantly different from those in other WFs. Moreover, the velocity distribution of the maser emission shows a &apos;'Hubble-like'&apos; flow (higher velocities at larger distances from the central star), consistent with a short-lived, explosive mass-loss event. This velocity pattern is not seen in other WFs (which are presumably in earlier evolutionary stages). We therefore suggest that we are witnessing a fundamental change of mass-loss processes in WFs, with water masers being pumped by steady jets in post-AGB stars, but tracing explosive/ballistic events as the object enters the PN phase.

    D&apos;&apos; represents one of the most dramatic thermal and compositional layers within our planet. In particular, global tomographic models display relatively fast patches at the base of the mantle along the circum-Pacific which are generally attributed to slab debris. Such distinct patches interact with the bridgmanite (Br) to post-bridgmanite (PBr) phase boundary to generate particularly strong heterogeneity at their edges. Most seismic observations for the D&apos;&apos; come from the lower mantle S wave triplication (Scd). Here we exploit the USArray waveform data to examine one of these sharp transitions in structure beneath Alaska. From west to east beneath Alaska, we observed three different characteristics in D&apos;&apos;: (1) the western region with a strong Scd, requiring a sharp δVs = 2.5% increase; (2) the middle region with no clear Scd phases, indicating a lack of D&apos;&apos; (or thin Br-PBr layer); and (3) the eastern region with strong Scd phase, requiring a gradient increase in δVs. To explain such strong lateral variation in the velocity structure, chemical variations must be involved. We suggest that the western region represents relatively normal mantle. In contrast, the eastern region is influenced by a relic slab that has subducted down to the lowermost mantle. In the middle region, we infer an upwelling structure that disrupts the Br-PBr phase boundary. Such an interpretation is based upon a distinct pattern of travel time delays, waveform distortions, and amplitude patterns that reveal a circular-shaped anomaly about 5° across which can be modeled synthetically as a plume-like structure rising about 400 km high with a shear velocity reduction of ~5%, similar to geodynamic modeling predictions of upwellings.

    The kinetics of the phagocytosis of 198-Au colloids by macrophages &apos;&apos;in vitro&apos;&apos; was studied by incubating during 5 hours phagocytic cells from the liver and the spleen of Wistar rats with colloidal radiogold particles, in the presence of an adequate culture medium (TC-199 with 10 per cent of Bovine Fetal Serum). In each experiment, the number of colloidal gold particles offered to each phatocytic cell, (Au)/sub 0/ and the mean rate of phagocytosis v, were calculated. The latter value was determined by measuring the radioactivity incorporated into the phagocytic cells during the incubation; it was expressed as the number of phagocytized colloidal gold particles per cell per minute. The values of log v = f (log (Au)/sub 0/) were plotted. The Lineweaver-Burk analysis of the results demonstrates that the kinetics of the phagocytosis of colloidal radiogold particles &apos;&apos;in vitro&apos;&apos; follows a model similar to Michaelis-Menten equations for enzyme reactions. The values of the substratum constant Ks and maximun velocity Vm were obtained by the regression analysis of the 1/v vs. 1/(Au)/sub 0/ graph. Vm was equal to 9.44 x 10 and 1.63 x 10 phagocytized colloidal gold particles per cell per minute for liver and spleen macrophages, respectively. Ks was equal to 6.01 x 10/sup 9/ and 8.02 x 10/sup 8/ colloidal gold particles per cell for liver and spleen macrophages, respectively. The significance of these differences is discussed and attributed mainly to a change of the specific engulfment rate constant.

    Field design changed substantially from extended-field RT (EF-RT) to involved-field RT (IF-RT) and now to involved-node RT (IN-RT) and involved-site RT (IS-RT) as well as treatment techniques in radiotherapy (RT) of Hodgkin&apos;s lymphoma (HL). The purpose of this article is to demonstrate the establishment of a quality assurance program (QAP) including modern RT techniques and field designs within the German Hodgkin Study Group (GHSG). In the era of modern conformal RT, this QAP had to be fundamentally adapted and a new evaluation process has been intensively discussed by the radiotherapeutic expert panel of the GHSG. The expert panel developed guidelines and criteria to analyse &apos;'modern'&apos; field designs and treatment techniques. This work is based on a dataset of 11 patients treated within the sixth study generation (HD16-17). To develop a QAP of &apos;&apos;modern RT&apos;&apos;, the expert panel defined criteria for analysing current RT procedures. The consensus of a modified QAP in ongoing and future trials is presented. With this schedule, the QAP of the GHSG could serve as a model for other study groups. (orig.) [German] Nicht nur die Zielvolumendefinitionen haben sich von der Extended-Field- (EF-RT) ueber die Involved-Field- (IF-RT) bis zur Involved-Node- (IN-RT) und Involved-Site-Radiotherapie (IS-RT) weiterentwickelt.

    The effects of irradiation dose and refrigerated storage conditions on &apos;Nagpur&apos; mandarin (Citrus reticulata Blanco), &apos;Mosambi&apos; sweet orange (Citrus sinensis Osbeck) and &apos;Kagzi&apos; acid lime (Citrus aurantifolia Swingle) were investigated. Mature fruits of these three species were treated with 0, 0.25, 0.5, 1 and 1.5 kGy radiation. &apos;Nagpur&apos; mandarin and &apos;Mosambi&apos; sweet oranges were stored at 6-7 deg. C and 90-95% r.h. for 75 and 90 days, respectively, while &apos;Kagzi&apos; acid limes were stored at 8{+-}1 deg. C and 90-95% r.h. for 90 days. Physico-chemical parameters, sensory attributes and respiration rate were measured besides losses and disorders. In &apos;Nagpur&apos; mandarin, radiation dose upto 1.5 kGy did not cause any rind disorder. Radiation treatments did not reduce the extent of decay. Penicillium rot was delayed in fruit treated with 1.5 kGy, while it appeared early in 0 kGy. Irradiation doses were ineffective to control rots due to Botryodiplodia theobromae and Alternaria citri. Doses upto 1.5 kGy did not cause any significant effect on fruit firmness and juice content; however, total soluble solids increased, while titratable acidity and vitamin &apos;C&apos; content decreased. Texture and flavour scores as recorded after a week, were not affected by irradiation except in 1.5 kGy. In &apos;Mosambi&apos; sweet orange, radiation treatments caused peel disorder in the form of brown sunken areas after 90 days and reduced fruit firmness, acidity and vitamin C content. The TSS content was higher in treated fruit. Flavour and texture were not affected by the doses of irradiation used. In treated acid limes (mature yellow), weight loss and decay were higher than untreated fruit (0 kGy) although difference was non-significant. Juice, TSS, titratable acidity and vitamin C contents were significantly less in treated fruit than in 0 kGy. Texture and flavour scores were also less in treated fruit than in 0 kGy. The

    Time was when a neophyte wanting to do experiments with neutrons would be told first to read D.J. Hughes&apos; classic &apos;&apos;Pile Neutron Research&apos;&apos; (1952). The book by J. Byrne is in many respects a modern equivalent, although if you were to send your student away with it, you will risk not seeing him or her again for a considerable time. What is immediately striking is that the book, rich in information and quite long, is cross-disciplinary and touches essentially all the main areas of modern physics. It covers parts of particle physics, such as the internal structure of the neutron, time-reversal violation as revealed by the (still hypothetical) electric dipole moment of the neutron, and the coupling constants for the weak interaction. From the field of basic quantum physics there are chapters on neutron optics, wave phenomena with neutrons and on the applications of these in solid-state physics. Other chapters again delve deeply into nuclear structure, nuclear reaction theory, as well as their applications: nuclear reactors and nuclear energy. At a time with specialization rampant and many physicists tending to believe that venturing outside their own cloisters is uninteresting and even dangerous, it is a pleasure to come across a book that is basically just about physics. J. Byrne of Sussex has for long been active in neutron research at the British-French-German Institut Laue-Langevin (ILL) research reactor in Grenoble, where he has worked on subjects such as weak interactions and fundamental symmetries. He has clearly intended &apos;&apos;Neutrons, Nuclei and Matter&apos;&apos; as a vade-mecum that will allow the practitioner to find the necessary information and formulas. But I believe that many others not directly engaged in neutron research will gain new insight from its many examples. To take just one case, I had not been aware of the simple physical principles that permit cold neutrons to be stored in a bottle. (The main point is that a

    Strong ferromagnetic-like response is observed at room temperature in &apos;'bulk'&apos;- and nano-crystalline Y-doped CeO{sub 2}. The saturation magnetization for &apos;'bulk'&apos; (∝600 nm) crystallites of CeO{sub 2} doped with 25 at.% Y is more than an order of magnitude higher compared to its nanocrystalline (∝10 nm) counterpart. High frequency electron spin resonance and {sup 89}Y nuclear magnetic resonance measurements indicate clustering of electronic defects in the &apos;'bulk'&apos; crystallites. The remarkable size dependence of the magnetic behavior likely originates from a collective magnetic response of defect-lined nanodomain interfaces in the &apos;'bulk'&apos; crystallites, consistent with the giant orbital paramagnetism model.

    We have discovered that microorganisms produce and emit the hydrocarbon isoprene (2-methyl-1,3-butadiene), and have suggested that if isoprene-producing enzymes and their genes can be harnessed, useful hydrocarbon-producing systems might be constructed. The main goal of the proposed work is to establish the biochemical mechanism and regulation of isoprene formation in the bacterial system, Bacillus subtilis. Specific objectives of the proposed work are the following: (A) to characterize the physiological regulation of isoprene formation in B. subtilis; (B) to characterize mutations in B. subtilis 168 that suppress isoprene formation, clone these genes, and determine how isoprene and isoprenoid carbon flow are regulated; and (C) to test &apos;'overflow'&apos; and &apos;'signaling'&apos; models for Bacillus isoprene formation. We are also pursuing the isolation and cloning of B. subtilis isoprene synthase, which we believe may be a regulatory enzyme.

    The unique beam-delivery technique of Tomotherapy machines (Accuray Inc., Sunnyvale, Calif.) necessitates tailored quality assurance. This requirement also applies to external dose intercomparisons. Therefore, the aim of the 2014 SSRMP (Swiss Society of Radiobiology and Medical Physics) dosimetry intercomparison was to compare two set-ups with different phantoms. A small cylindrical Perspex phantom, which is similar to the IROC phantom (Imaging and Radiation Oncology Core, Houston, Tex.), and the &apos;'cheese'&apos; phantom, which is provided by the Tomotherapy manufacturer to all institutions, were used. The standard calibration plans for the TomoHelical and TomoDirect irradiation techniques were applied. These plans are routinely used for dose output calibration in Tomotherapy institutions. We tested 20 Tomotherapy machines in Germany and Switzerland. The ratio of the measured (D{sub m}) to the calculated (D{sub c}) dose was assessed for both phantoms and irradiation techniques. The D{sub m}/D{sub c} distributions were determined to compare the suitability of the measurement set-ups investigated. The standard deviations of the TLD-measured (thermoluminescent dosimetry) D{sub m}/D{sub c} ratios for the &apos;'cheese'&apos; phantom were 1.9 % for the TomoHelical (19 measurements) and 1.2 % (11 measurements) for the TomoDirect irradiation techniques. The corresponding ratios for the Perspex phantom were 2.8 % (18 measurements) and 1.8 % (11 measurements). Compared with the Perspex phantom-based set-up, the &apos;'cheese'&apos; phantom-based set-up without individual planning was demonstrated to be more suitable for Tomotherapy dose checks. Future SSRMP dosimetry intercomparisons for Tomotherapy machines will therefore be based on the &apos;'cheese'&apos; phantom set-up. (orig.)

    This collection of short articles is dedicated to the promotion of the Swiss &apos;Minergie&apos; building standard, covering the following points: &apos;Minergie&apos; - a standard for the future; well-insulated and air-tight - two of the three main &apos;Minergie&apos; requirements; solar collectors as a &apos;Minergie&apos; component; radiators for low-energy-consumption buildings; hot water from the sun on six out of seven days; the &apos;Minergie&apos; module as a factor for success; the &apos;Habitus&apos; ventilation unit - a new Swiss product. The first contribution introduces the &apos;Minergie&apos; Standard. Its application in the building and building technical services trades offers from considerable advantages and opportunities for profit. The Standard, which aims to increase the comfort and reduce the energy consumption of buildings, is introduced and the basic principles involved, including energy usage figures, are discussed. A second contribution describes two of the three main requirements for reaching the &apos;Minergie&apos; Standard, air-tightness and good thermal insulation. The main advantage of the standard - a higher level of comfort - is emphasised and an example is given. The third short article takes a look at the use of thermal solar collectors as a source of heat in &apos;Minergie&apos; buildings. A solution involving a combined solar heating and hot-water supply is discussed. The fourth contribution discusses the use of low-temperature radiators in &apos;Minergie&apos; buildings. Examples are given of heat requirements calculation and the factors involved in dimensioning the radiators are discussed. A fifth article describes a commercially available compact solar hot-water system and discusses questions of solar fraction. Returning to basic aspects, the sixth contribution introduces a labelling system for the various components of a &apos;Minergie&apos; building - such as ventilation units, insulation material, radiators, boilers etc

    This paper investigates a method of reconstructing images from energy-resolved CT data with negligible beam-hardening artifacts and improved contrast-to-nosie ratio (CNR) compared to conventional energy-weighting methods. Conceptually, the investigated method first reconstructs separate images from each energy bin. The final image is a linear combination of the energy-bin images, with the weights chosen to maximize the CNR in the final image. The optimal weight of a particular energy-bin image is derived to be proportional to the contrast-to-noise-variance ratio in that image. The investigated weighting method is referred to as &apos;'image-based'&apos; weighting, although, as will be described, the weights can be calculated and the energy-bin data combined prior to reconstruction. The performance of optimal image-based energy weighting with respect to CNR and beam-hardening artifacts was investigated through simulations and compared to that of energy integrating, photon counting, and previously studied optimal &apos;'projection-based'&apos; energy weighting. Two acquisitions were simulated: dedicated breast CT and a conventional thorax scan. The energy-resolving detector was simulated with five energy bins. Four methods of estimating the optimal weights were investigated, including task-specific and task-independent methods and methods that require a single reconstruction versus multiple reconstructions. Results demonstrated that optimal image-based weighting improved the CNR compared to energy-integrating weighting by factors of 1.15-1.6 depending on the task. Compared to photon-counting weighting, the CNR improvement ranged from 1.0 to 1.3. The CNR improvement factors were comparable to those of projection-based optimal energy weighting. The beam-hardening cupping artifact increased from 5.2% for energy-integrating weighting to 12.8% for optimal projection-based weighting, while optimal image-based weighting reduced the cupping to 0

    Microglia are the brains&apos; resident immunocompetent cells that can be activated by acute as well as chronic pathological stimuli. When activated they express the peripheral benzodiazepine binding site to which the isoquinolin PK11195 binds with high specificity. Labelled with [{sup 11}C], the R-enatiomer [{sup 11}C] PK1195 has been used for positron emission tomography (PET) studies to demonstrate neuroinflammatory changes in vivo. [{sup 11}C](R) PK11195-PET has been successfully used to show in vivo microglial activation in ischemic (stroke), inflammatory (multiple sclerosis) and degenerative (Alzheimer&apos;s and Parkinson&apos;s disease). Longitudinal studies are in progress to help to clarify the relationship between localisation and extent of microglial activation and the clinical presentations in these disorders. This will help to determine the role of [{sup 11}C](R) PK11195 PET as a diagnostic tool and a surrogate marker of &apos;'neuroinflammation'&apos; in therapeutic trials. (orig.)

    The superregenerative principle has been known since the early 1920s. The circuit is extremely simple and extremely sensitive. Today, superheterodyne receivers generally supplant superregenerative receivers in most applications because there are several undesirable characteristics: poor selectivity, reradiation, etc. Superregenerative receivers undergo a revival in recent papers for wireless systems, where low cost and very low power consumption are relevant: house/building meters (such as water, energy, gas counter), personal computer environment (keyboard, mouse), etc. Another drawback is the noise level which is higher than that of a well-designed superheterodyne receiver; without an antenna input signal, the output of the receiver hears in an earphone as a waterfall noise; this sound principally is the inherent input noise amplified and detected by the circuit; however, when the input noise is negligible with respect of an antenna input signal, we are faced to an other source of &apos;noise&apos; self-generated by the superregenerative working. The main objective of this paper concerns this self-generated noise coming from an exponential growing followed by a re-injection process for which the final state is a function of the phase of the input signal.

    This decision from the French authority of nuclear safety (ASN) aims at validating the new versions of the guidebook for the elaboration of &apos;waste studies&apos; for nuclear facilities and of the specifications for the elaboration of &apos;waste statuses&apos; for nuclear facilities. This paper includes two documents. The first one is a guidebook devoted to nuclear facility operators which fixes the rules of production of waste studies according to the articles 20 to 26 of the inter-ministry by-law from December 31, 1999 (waste zoning conditions and ASN&apos;s control modalities). The second document concerns the specifications for the establishment of annual waste statuses according to article 27 of the inter-ministry by-law from December 31, 1999 (rational management of nuclear wastes).

    &apos;&apos;What if electronics devices are printed using an inkjet printer even at home?&apos;&apos; &apos;&apos;What if those devices no longer need a battery?&apos;&apos; I will introduce two enabling technologies for the Internet of Things concept. 1. Instant Inkjet Circuits: A low cost, fast and accessible technology to support the rapid prototyping of electronic devices. We demonstrated that &apos;'sintering-free'&apos; silver nano particle ink with a commodity inkjet printer can be used to fabricate printed circuit board and high-frequency applications such as antennas and sensors. The technology is now commercialized by AgIC, Inc. 2. Wireless Power: Although large amounts of data can be exchanged over a wireless communication link, mobile devices are still tethered by power cables. We are trying to solve this problem by two different approaches: energy harvesting. A simple circuitry comprised of diodes and capacitor can convert ambient radio signals into DC current. Our research revealed the signals from TV tower located 6.5km apart could be used to feed 100 microwatts to power microcontrollers

    This paper describes the testing and corresponding results of the preparation &apos;'Rhoder'&apos; in comparison with several other bioremediation variants during the field trials in Komi Republic throughout 2002-2003. All bioremediation trials were performed on one vast polar marshy wetland polluted by accidental crude oil spill and uncovered by grass. After application of the &apos;'Rhoder'&apos; at the site, with an area of {approx} 2000 m{sup 2}, during the cold and rainy summer of 2002 (1.5 months), the level of oil contamination decreased by 20-51%, depending on initial oil pollution (458-738 g/kg dry weight of soil). In the middle of September 2002, the treated site was covered by 70-85% with green grass. Though, during 2003, the &apos;'Rhoder'&apos; treatment was not practised, at the end of August 2003, the site was already covered by 85-95% with green grass and the level of oil contamination further decreased by 54-79% from the initial level of oil pollution at the beginning of 2002. These results were much better compared to those from other bioremediation variants applied at this spill. (author)

    The spectral density of fluctuations in the audio power of many musical selections and of English speech varies approximately as 1/f (f is the frequency) down to a frequency of 5 x 10/sup -4/ Hz. This result implies that the audio-power fluctuations are correlated over all times in the same manner as &apos;&apos;1/f noise&apos;&apos; in electronic components. The frequency fluctuations of music also have a 1/f spectral density at frequencies down to the inverse of the length of the piece of music. The frequency fluctuations of English speech have a quite different behavior, with a single characteristic time of about 0.1 s, the average length of a syllable. The observations on music suggest that 1/f noise is a good choice for stochastic composition. Compositions in which the frequency and duration of each note were determined by 1/f noise sources sounded pleasing. Those generated by white-noise sources sounded too random, while those generated by 1/f/sup 2/ noise sounded too correlated.

    &apos;&apos;Midline granuloma syndrome&apos;&apos; encompasses a number of specific clinicopathologic entities, such as &apos;'Wegener&apos;s granulomatosis, midline malignant reticulosis, lymphoma, nasal carcinoma and a broad spectrum of infectious diseases. In the course of studying a number of patients presenting with destructive lesions of the upper respiratory tract, 11 cases emerged as having unique clinicopathologic features. These are: 1) presence of locally destructive lesions which are always restricted to the upper respiratory tract. 2) Absence of systemic disease during a follow-up period of six months to 18 years (mean 7.3 years). On examination of repeated biopsy specimens the histopathologic picture consisted of acute and chronic inflammation with variable amounts of necrosis. Granulomata were seen in one case. Malignant or atypical cells were invariably absent. Frank vasculitis was not seen, although in five of the patients inflammatory cells in the wall of small vessels were conspicuous 4) Inability to demonstrate an infectious origin by culture or special stains. Radiation therapy has proven effective in patients with this entity, for which the term &apos;&apos;Idiopathic Midline Destructive Disease&apos;&apos; (IMDD) is proposed.

    Probing the matter in order to check its elementary constituents, that is the goal of the particle physic. In this field, the experiments consist in colliding highly energetic particle beams and observing the new born particles. These observations are based on big particle detectors whose running is dependant on the precise knowledge of their geometry (position of the detection chambers). To achieve this, the detectors are equipped with alignment sensors, which have to be calibrated before. This document describes the study and the making of a calibration bench for the &apos;Praxial&apos; (PRoximity AXIAL) type sensors, and other works related to these sensors. In a first part, we determine and apply a method to set the tools used to fix the sensor stands on the detection chambers. These settings are made with the use of a tridimensional measuring machine. Then, we study the stands themselves. These investigations concern mechanics: positioning quality of the sensors in their stands, bending of the supports due to the tightening. In this part too, the studies are in the field of dimensional metrology. After this, the works are reoriented toward the bench, with the choice of the displacement sensors among two different technologies: optical, with the Rasnik system, and mechanical, with linear probes as LVDT (Linear Variable Differential Transformer). Following the discovery of an ambiguity on the Rasnik system, we go on the tests to understand its behaviour. We introduce the theory of the alignment sensors calibration, which is based on a minimization calculation. The computer programs are explained in a chapter, and in an other, the implementation of the quality assurance procedures. An other part describes the mechanical studies and the problems they cause. Because of a delay onset of the project, we make a model of the bench. This dummy allows us to test every single function of the final bench. With this device, we record manually the first calibration data and

    It is known that the oxygenation of living tissues increases the effect of irradiation. Thus it&apos;s convenient to oxygen tumor tissues and to know, before irradiation, the change of concentration of available oxygen already in it, between the sealed surface and the furthest depth of penetration or interface. In the present work we solve a model proposed by J. Cranck and R. Gupta, that describes thediffusion of oxygen in living tissues. Landau&apos;s transformation we used and finite differences for approximating the problem. We describe two implicit algorithms. The transformation allows to work with a fixed number of nodes during all the simulation. (author)

    We previously reported a negative association of circulating plasmalogens (phospholipids with proposed atheroprotective properties) with coronary artery disease. Plasmalogen modulation was previously demonstrated in animals but its effect on atherosclerosis was unknown. We assessed the effect of plasmalogen enrichment on atherosclerosis of murine models with differing levels of oxidative stress. Six-week old ApoE- and ApoE/glutathione peroxidase-1 (GPx1)-deficient mice were fed a high-fat diet with/without 2% batyl alcohol (precursor to plasmalogen synthesis) for 12 weeks. Mass spectrometry analysis of lipids showed that batyl alcohol supplementation to ApoE- and ApoE/GPx1-deficient mice increased the total plasmalogen levels in both plasma and heart. Oxidation of plasmalogen in the treated mice was evident from increased level of plasmalogen oxidative by-product, sn-2 lysophospholipids. Atherosclerotic plaque in the aorta was reduced by 70% (P = 5.69E-07) and 69% (P = 2.00E-04) in treated ApoE- and ApoE/GPx1-deficient mice, respectively. A 40% reduction in plaque (P = 7.74E-03) was also seen in the aortic sinus of only the treated ApoE/GPx1-deficient mice. Only the treated ApoE/GPx1-deficient mice showed a decrease in VCAM-1 staining (-28%, P = 2.43E-02) in the aortic sinus and nitrotyrosine staining (-78%, P = 5.11E-06) in the aorta. Plasmalogen enrichment via batyl alcohol supplementation attenuated atherosclerosis in ApoE- and ApoE/GPx1-deficient mice, with a greater effect in the latter group. Plasmalogen enrichment may represent a viable therapeutic strategy to prevent atherosclerosis and reduce cardiovascular disease risk, particularly under conditions of elevated oxidative stress and inflammation.

    We encountered so-called &apos;'carcinosarcoma,'&apos; i.e., mixed carcinoma and sarcoma in the same tissue. A 73-year-old man attained &apos;'complete'&apos; recovery (CR) in chemotherapy and radiation therapy for moderately differentiated squamous cell carcinoma of the hypopharynx, classified as T2N0M0. During follow-up, an irregular grayish white mass of 3 cm was detected. Based on a diagnosis of recurrent hypopharyngeal carcinoma, we conducted pharyngolaryngoesophagectomy, bilateral modified dissection, and reconstruction with a free jejunal graft. The resected specimen, stained with HE, was histopathologically determined to be squamous cell carcinoma with styloid cornification tendency, whereas spindle cells markedly proliferated over the entire mass. On immunohistological staining, sarcomatous spindle cells were positive for EMA and cytokeratin, showing they were derived from the epithelium, resulting in a definite diagnosis of so-called carcinosarcoma&apos;&apos; thought to result from transformation from squamous cell carcinoma to the sarcomatous tumor due to radiation therapy. This patient has remained relapse-free in the 3.5 years since the last operation. (author)

    &apos;Dose-painting&apos; radiotherapy allows for a heterogeneous delivery of radiation within the tumour volume by targeting radioresistant areas defined by functional imaging. Within gross tumour volume, it is possible to define one or more target volumes based on biology (biological target volume [BTV]) and to apply a strategy of intensity modulated radiation therapy (IMRT) that will deliver a higher dose to these regions. In this review of the literature, we will highlight the biological elements responsible for radioresistance, and how to image them, then we will detail the radiotherapy techniques necessary for this approach, before presenting clinical results in various situations (head and neck tumours, prostate, brain tumours, etc.). Despite many difficulties that make dose-painting IMRT unusable in routine nowadays, biology-guided radiation therapy represents one of the major pathways of development of radiotherapy in the coming years.

    125 non-overexposed patients who had been treated in the same time period and for the same cancer sites as the overexposed patients. The clinicians uncovered a larger recurrence of cervical cancers than expected. The finding prompted PAHO to launch an initiative for the accreditation of radiation oncology centers in Latin America and the Caribbean, working in collaboration with professional societies for radiation oncologists, medical physicists, and radiotherapy technologists. The Latin American Association for Radiation Oncology (Asociación Latinoamericana de Terapia Radiante Oncológica has established an accreditation commission. Accreditation will require that centers implement a comprehensive radiation oncology quality assurance program that follows international guidelines. Statistical data on patient outcomes will be collected in order to document needs in radiotherapy centers in Latin America and the Caribbean and to define future strategies for cancer treatment.Este informe resume y analiza la respuesta de varias organizaciones que brindaron asistencia al Instituto Oncológico Nacional (ION de Panamá después de la sobreexposición de 28 pacientes sometidos a radioterapia que ocurrió en el ION a finales de 2000 y principios de 2001. Además, se examinan las medidas de largo plazo adoptadas en el ION en respuesta al accidente de sobreexposición y las implicaciones que tiene este accidente para todos los centros de tratamiento oncológico en el mundo. En marzo de 2001 se le comunicaron al director del ION las reacciones adversas graves sufridas por algunos pacientes sometidos a radioterapia contra el cáncer. De los 478 pacientes tratados entre agosto de 2000 y marzo de 2001 por cánceres localizados en la región pélvica, tres habían fallecido, presumiblemente por sobredosis de radiación.

    Purpose: To prospectively assess the spectrum of brain CT findings in psychiatric patients and to determine the number of patients that had an underlying cause for the symptoms. Patients and methods: Over a period of six months, 142 patients (78 males, 64 females; median age 61 [18-91] years) were referred for CT brain scans. Their scans were reviewed, along with the clinical information that was provided in the request form. All the hard copies were reviewed to assess areas of ischaemia, infarction, atrophy, tumours, and haematomas. The majority of requests were to exclude vascular event or space-occupying lesions. Clinical indications included mood disorders (depression, mania), schizophrenic disorders, dementia, personality and behavioural disorders. Results: 31 (22%) were normal. 111 (78%) had varying degrees of ischaemia, infarction and cerebral/cerebellar atrophy. 7 (4.9%) had space-occupying lesions which included two gliomas and five meningiomas. There were two chronic subdural haematomas and one arteriovenous malformation. Conclusion: 1. In our series, pathologic findings in &apos;routine&apos; brain CT&apos;s were encountered in 78%. 2. The incidence of brain tumours was 4.9%, compared with 0.00005% of the general population. 3. CT scanning in psychiatric patients is cost-effective and especially indicated when there is an atypical presentation, or inadequate response to standard treatment. (orig.)

    To examine the anatomic MRI characteristics of the adductor magnus mini hamstring (AMMH) and explore its involvement in cases of hamstring avulsion. An IRB-approved retrospective review of patients undergoing &apos;&apos;hamstring protocol&apos;&apos; MRI between March 2009 and June 2014 was performed. Two musculoskeletal radiologists recorded multiple AMMH anatomic characteristics and involvement in cases of hamstring avulsion. Seventy-six AMMHs were analyzed in 66 patients [35 females and 31 males, mean age 49.3 ± 15.2 years (range 17-81)]. Eleven percent of AMMHs were poorly visualized, 51 % visualized, and 37 % well visualized. Seven percent demonstrated round, 73 % ovoid, and 21 % flat/lenticular tendon morphologies. Most (88 %) demonstrated typical origins. Average cross-sectional area (CSA) was 22.4 ± 10.6 mm{sup 2} (range 6-56), diameter was 7.2 ± 2.5 mm (range 2.9-15), medial distance from the semimembranosus tendon was 7.5 ± 2.5 mm (range 3-14), and tendon length was 6.8 ± 3.3 cm (range 1.2-14.1). There was no gender difference in AMMH anatomic measurements or correlation between age and CSA or diameter. Of 17 complete hamstring avulsion cases, the AMMH was intact in 13, partially torn in 3, and completely torn in 1. The AMMH is a constant finding with variable anatomic characteristics. It is visualized or well visualized by MRI in 88 % of cases and is a sizable tendon located in close proximity to the semimembranosus tendon. Because it is uncommonly completely torn (6 %) in cases of complete hamstring avulsion, radiologists should be aware of its presence and appearance to avoid diagnostic confusion. (orig.)

    2005-01-15

    This is the final report for a one year close out extension of our basic research program that was established at the University of Chicago more than sixteen years ago to explore and develop the optical sub-discipline that has come to be known as &apos;&apos;nonimaging optics&apos;&apos;. This program has been extremely fruitful, having both broadened the range of formalism available for workers in this field and led to the discovery of many new families of optical devices. These devices and techniques have applications wherever the efficient transport and transformation of light distributions are important, in particular in illumination, fiber optics, collection and concentration of sunlight, and the detection of faint light signals in physics and astrophysics. Over the past thirty years, Nonimaging Optics (Welford and Winston, 1989) has brought a fresh approach to the analysis of many problems in classical macro-scale optics. Through the application of phase-space concepts, statistical methods, thermodynamic arguments, etc., many previously established performance limits were able to be broken and many technical surprises with exciting practical applications were discovered. The most recent three-year phase of our long-term continuing program ended in late 2002 and emphasized extending our work in geometrical optics and expanding it to include some interesting questions in physical optics as well as in the new field of statistical optics. This report presents a survey of the basic history and concepts of nonimaging optics and reviews highlights and significant accomplishments over the past fifteen years. This is followed by a more detailed summary of recent research directions and accomplishments during the last three years. This most recent phase was marked by the broadening in scope to include a separate project involving a collaboration with an industrial partner, Science Applications International Corporation (SAIC). This effort was proposed and approved in

    The United States Department of Energy initiated the Nuclear Energy Research Initiative (NERI) to conduct research and development with the objectives of: (1) overcoming the principal technical obstacles to expanded nuclear energy use, (2) advancing the state of nuclear technology to maintain its competitive position in domestic and world markets, and (3) improving the performance, efficiency, reliability, and economics of nuclear energy. Fiscal Year 1999 program funding is $19 Million, with increased finding expected for subsequent years, emphasizing international cooperation. Among the programs selected for funding is the ``Smart Equipment and Systems to Improve Reliability and Safety in Future Nuclear Power Plant Operations&apos;&apos;. This program is a 30 month collaborative effort bringing together the technical capabilities of ABB C-E Nuclear Power, Inc. (ABB CENP), Sandia National Laboratories, Duke Engineering and Services (DE and S), Massachusetts Institute of Technology (MIT) and Pennsylvania State University (PSU). The program&apos;s goal is to design, develop and evaluate an integrated set of smart equipment and predictive maintenance tools and methodologies that will significantly reduce nuclear plant construction, operation and maintenance costs. To accomplish this goal the Smart Equipment program will: (1) Identify and prioritize nuclear plant equipment that would most likely benefit from adding smart features; (2) Develop a methodology for systematically monitoring the health of individual pieces of equipment implemented with smart features (i.e. smart equipment); (3) Develop a methodology to provide plant operators with real-time information through smart equipment Man-Machine Interfaces (MMI) to support their decision making; (4) Demonstrate the methodology on a targeted component and/or system; (5) Expand the concept to system and plant levels that allow communication and integration of data among smart equipment.

A retrospective review was conducted of 46 MRI examinations evaluating diabetic foot ulcers that demonstrated normal T1 marrow signal, but T2 marrow hyperintensity deep to the ulcer. The cohort was divided based on MRI report impressions into three groups; &apos;&apos;osteitis without osteomyelitis&apos;&apos; (OW), &apos;&apos;osteitis but cannot exclude early osteomyelitis&apos;&apos; (OCEO) and &apos;&apos;early osteomyelitis&apos;&apos; (EO). Patient demographics (age, gender) and accessory MRI findings of ulcer and sinus tract depth were recorded. Initial clinical assessment and medical treatment (route and duration of antibiotics), healing versus disease progression and histology or microbiology results were recorded. The isolated marrow T2 signal hyperintensity was reported as OW in 12 patients, OCEO in 18, and EO in 16. No statistical difference in clinical assessment was demonstrated between the OW, OCEO, and EO groups. Pathological condition was available in 15 patients within 0-7 days (mean 2.4 days) of the MRI examination, with 14 (93%) of these positive for osteomyelitis by histopathology or positive cultures. Initial diagnosis of or progression to osteomyelitis was shown in 28 patients (61%). Treatment of suspected osteomyelitis is heavily determined by clinical factors. Patients who initially demonstrate only T2 marrow signal abnormality under a diabetic ulcer are eventually diagnosed as osteomyelitis in 61% of cases and deserve aggressive treatment as early osteomyelitis when meeting clinical parameters.

    On December 13, 2011, Luc Oursel, CEO, and Pierre Aubouin, Chief Financial Officer presented the group&apos;s strategic plan for the period 2012-2016. The plan has been drawn up collectively and is based on a thorough-going analysis and a realistic assessment of perspectives for all group activities and associated resources. Development of nuclear and renewable energies: the fundamentals are unchanged. In this context, the German decision remains an isolated case and the great majority of nuclear programs around the world have been confirmed. More conservative in its projections than the International Energy Agency, the group expects growth of 2.2% annually, reaching 583 GW of installed nuclear capacity by 2030, against 378 GW today. However, the Fukushima accident will lead to delays in launching new programs. &apos;Action 2016&apos; plan aims to consolidate AREVA&apos;s leadership in nuclear energy and become a leading player in renewable energy. The group&apos;s strategic action plan &apos;Action 2016&apos; is based on the following strategic choices: - commercial priority given to value creation, - selectivity in investments, - strengthening of the financial structure. These demand an improvement in the group&apos;s performance by 2015. This plan makes nuclear safety a strategic priority for the industrial and commercial performance of the group. This ambitious performance plan for the period 2012-2016 will give the group the wherewithal to withstand a temporary slowdown in the market resulting from the Fukushima accident and to deliver safe and sustainable growth of the business. The plan sets out the strategic direction for the group&apos;s employees for the years ahead: taking advantage of the expected growth in nuclear and renewable energies, targeted investment programs, and return to self-financing as of 2014

    In the food industry, injuries due to food poisoning have been increasing. Especially the mass outbreak of food poisoning by Escherichia coli such as O-157 in 1996 gave warning on the importance of food sanitation management. Public efforts such as the Hazard Analysis and Critical Control Point (HACCP) system have been made to prevent food poisoning. Recently, disinfection made by electrolyzing water with some salt added has attracted attention. Fuji Electric has developed the generator &apos;SaniBoy&apos; that produces weak alkaline electrolyzed water without wasting water. The environment-friendly &apos;SaniBoy&apos; will contribute to sanitation in various fields. (author)

    2015-01-16

    The Resource Description Framework (RDF) and SPARQL Protocol and RDF Query Language (SPARQL) were introduced about a decade ago to enable flexible schema-free data interchange on the Semantic Web. Today data scientists use the framework as a scalable graph representation for integrating, querying, exploring and analyzing data sets hosted at different sources. With increasing adoption, the need for graph mining capabilities for the Semantic Web has emerged. Today there is no tools to conduct "graph mining" on RDF standard data sets. We address that need through implementation of popular iterative Graph Mining algorithms (Triangle count, Connected component analysis, degree distribution, diversity degree, PageRank, etc.). We implement these algorithms as SPARQL queries, wrapped within Python scripts and call our software tool as EAGLE. In RDF style, EAGLE stands for "EAGLE &apos;Is an&apos; algorithmic graph library for exploration. EAGLE is like &apos;MATLAB&apos; for &apos;Linked Data.&apos;

    The variations of near-infrared red reflectance ratios of ten aridic soil samples were correlated with a &apos;&apos;redness index&apos;&apos; computed from red and green spectral bands. These variations have been shown to limit the performances of vegetation indices (NDVI and SAVI) in discriminating low vegetation covers. The redness index is used to adjust for this &apos;&apos;soil noise&apos;&apos;. Dala simulated for vegetation densities of 5 to 15% cover showed that the sensitivity of the corrected vegetation indices was significantly improved. Specifically, the &apos;'noise-corrected'&apos; SAVI was able to assess vegetation amounts with an error four times smaller than the uncorrected NDVI. These promising results should lead to a significant improvement in assessing biomass in arid lands from remotely sensed data. (author) [fr

  5. &apos;Green&apos; preferences as regulatory policy instrument

    2006-01-01

    We examine here the suggestion that if consumers in sufficient numbers are willing to pay the premium to have power generated using low-emission technologies, tax or permit policies become less necessary or stringent. While there are implementation difficulties with this proposal, our purpose is more fundamental: Can economics make sense of using preferences as a regulatory instrument? If &apos;green&apos; preferences are exogenously given, to what extent can or should they be regarded as a substitute for other policies? Even with &apos;green&apos; preferences, production and consumption of polluting goods continue to impose social costs not borne in the market. Moreover, if green preferences are regarded as a policy instrument, the &apos;no policy&apos; baseline would require a problematic specification of counterfactual &apos;non-green&apos; preferences. Viewing green preferences as a regulatory policy instrument is conceptually sensible if the benchmark for optimal emissions is based on value judgments apart from the preferences consumers happen to have. If so, optimal environmental protection would be defined by reference to ethical theory, or, even less favorably, by prescriptions from policy advocates who give their own preferences great weight while giving those of the public at large (and the costs they bear) very little consideration.

    The coexistence of pregnancy and cancer is a challenging situation for the physician. Chemotherapy and radiotherapy are often necessary, depending on the type and stage of cancer at diagnosis. When applying such treatment, several key points concerning the health of the fetus must be carefully monitored. Meanwhile, if the appropriate treatment is delayed until postpartum, the mother&apos;s life may be at risk. Historically, the mother&apos;s health was placed above that of the fetus. This concept has changed, and harmonization of maternal and fetal health is now considered ideal. Numerous reports have shown the safe use of chemotherapy especially during the second and third trimesters of pregnancy. In 2004 our department treated seven cases of simultaneous cancer and pregnancy, leading us to review the use of chemotherapy and radiotherapy during pregnancy and the repercussions on neonatal outcome.

  10. What &apos;cultural&apos; approach of electricity history?

    International Nuclear Information System (INIS)

    Beltran, Alain

    2004-01-01

    The evolution of electricity consumption should be related to social and cultural change. To understand this change better, we should use the notion of &apos;mentalities&apos;, which is less vague than &apos;culture&apos; and permits us to include practices in a dynamic totality. It is true that the study of consumers is difficult since they do not appear much in business archives. We must study the literature, advertisement and art of the time. Electricity was given its fairy status by the press. Before 1914, many myths, both frightening and reassuring, circulated around this form of energy. It is only during the Inter-war period that electricity had been degraded from the status of goddess to the one of maid. And yet, it did keep its double aspect of a soft and dangerous form of energy, as shown by its mid-1970&apos;s marriage to nuclear energy. A comparative cultural history of electricity remains to be done

    Radiomics, a recently introduced concept, describes quantitative computerized algorithm-based feature extraction from imaging data including computer tomography (CT), magnetic resonance imaging (MRT), or positron-emission tomography (PET) images. For radiation oncology it offers the potential to significantly influence clinical decision-making and thus therapy planning and follow-up workflow. After image acquisition, image preprocessing, and defining regions of interest by structure segmentation, algorithms are applied to calculate shape, intensity, texture, and multiscale filter features. By combining multiple features and correlating them with clinical outcome, prognostic models can be created. Retrospective studies have proposed radiomics classifiers predicting, e. g., overall survival, radiation treatment response, distant metastases, or radiation-related toxicity. Besides, radiomics features can be correlated with genomic information (&apos;'radiogenomics'&apos;) and could be used for tumor characterization. Distinct patterns based on data-based as well as genomics-based features will influence radiation oncology in the future. Individualized treatments in terms of dose level adaption and target volume definition, as well as other outcome-related parameters will depend on radiomics and radiogenomics. By integration of various datasets, the prognostic power can be increased making radiomics a valuable part of future precision medicine approaches. This perspective demonstrates the evidence for the radiomics concept in radiation oncology. The necessity of further studies to integrate radiomics classifiers into clinical decision-making and the radiation therapy workflow is emphasized. (orig.)

Among the technical aspects that influence in the equipment acceptance tests, it is the collimation type, the characteristics of the lineal accelerator, the platform for planning and the network type. In the case of the collimation system and the accelerator characteristics, we consider the manufacturer&apos;s specifications and requirements of Mexican Official Standard NOM-033-NUCL-1999, {sup T}echnical Specifications for the Teletherapy Units Operation, Linear Accelerators{sup .} Planning for the platform takes into account the manufacturer&apos;s specifications.

    The method proposed is designed for the study of neutronic properties of a sample (its material buckling, for example) and consists in submitting the sample to uniform surface density irradiation, its surface being a sphere or a cylinder which is supposed, temporarily, to be infinite. Neutron density in the sample will thus be uniform if its laplacian is nil: any curve in the distribution clearly indicating its absorbent or multiplying properties. In the case of a sample with multiplying power, density is identical to that in an active core, thus measurement of buckling will be free from considerable systematic error causes. The thermic equivalent of this type of irradiation would be a thermostat with an external heat source distributed uniformly over its surface: its temperature would be uniform. It is this analogy that has led us to baptize it the &apos;Neutrostat&apos;. (author)Fren.

    Full Text Available A radioterapia é um dos fatores desencadeantes do hipopituitarismo, mesmo quando não direcionada diretamente para o eixo hipotálamo-hipofisário, podendo resultar em redução de hormônios adeno-hipofisários, principalmente por lesão hipotalâmica. A perda da função da hipófise anterior é progressiva e geralmente na seguinte ordem: hormônio do crescimento, gonadotrofinas, adrenocorticotrofina e o hormônio estimulante da tireóide. Vários testes estão disponíveis para a confirmação das deficiências, sendo discutidos, neste artigo, os melhores testes para pacientes submetidos à irradiação. Enfatizamos que o desenvolvimento do hipopituitarismo após a radioterapia é dose e tempo dependente de irradiação, com algumas diferenças entre os eixos hipofisários. Portanto, a conscientização da necessidade de terapia em conjunto de endocrinologistas e oncologistas otimizará o tratamento e a qualidade de vida do paciente.Hypopituitarism can be caused by radiation therapy, even when it is not directly applied on the hypothalamic-pituitary axis, and can lead to anterior pituitary deficiency mainly due to hypothalamic damage. The progressive loss of the anterior pituitary hormones usually occurs in the following order: growth hormone, gonadotropin hormones, adrenocorticotropic hormone and thyroid-stimulating hormone. Although there are several different tests available to confirm anterior pituitary deficiency, this paper will focus on the gold standard tests for patients submitted to radiation therapy. We emphasize that the decline of anterior pituitary function is time- and dose-dependent with some variability among the different axes. Therefore, awareness of the need of a joint management by endocrinologists and oncologists is essential to improve treatment and quality of life of the patients.

    The US Department of Energy (DOE) laboratories have a long history of excellence in performing research and development in a number of areas, including the basic sciences, applied-energy technology, and weapons-related technology. Although technology transfer has always been an element of DOE and laboratory activities, it has received increasing emphasis in recent years as US industrial competitiveness has eroded and efforts have increased to better utilize the research and development resources the laboratories provide. This document, Technology &apos;90, is the latest in a series that is intended to communicate some of the many opportunities available for US industry and universities to work with the DOE and its laboratories in the vital activity of improving technology transfer to meet national needs. Technology &apos;90 is divided into three sections: Overview, Technologies, and Laboratories. The Overview section describes the activities and accomplishments of the DOE research and development program offices. The Technologies section provides descriptions of new technologies developed at the DOE laboratories. The Laboratories section presents information on the missions, programs, and facilities of each laboratory, along with a name and telephone number of a technology transfer contact for additional information. Separate papers were prepared for appropriate sections of this report.

    We investigate the teleportation scheme of two-mode squeezed states proposed by Adhikari et al.[S. Adhikari et al., Phys. Rev. A 77, 012337 (2008)]. It uses four-mode entangled states to teleport two-mode squeezed states. The fidelity between the original two-mode squeezed states and teleported ones is calculated. The maximal fidelity value of Adhikari&apos;s protocol is 0.38, which is incompatible with the fidelity definition with the maximal value 1. In our opinion, one reason is that they calculate the fidelity for multimodes Gaussian states using the fidelity formula for single-mode ones. Another reason is that the covariance matrix of output states should be what is obtained after applying the linear unitary Bogoliubov operations (two cascaded Fourier transformations) on the covariance matrix given in Eq. (12) in their paper. These two reasons result in the incomparable results. In addition, Adhikari&apos;s protocol can be simplified to be easily implemented.

    This article celebrates the successes of the Canadian independent oil contractors and the oilfield service and supply sector that keep Canada in the forefront of the world&apos;s &apos;smart&apos; nations in energy stewardship, efficiency, development, diversification and utilization. It explains how small independent contractors and service and supply enterprises play a central role on all these fronts, with supply and service companies being responsible for about 80 per cent of oil companies&apos; capital budget and 70 per cent of their operational expenditures in fields ranging from construction, and camp catering, to ambulance services, safety systems, trucking, tool making, drilling services, production testing, valve manufacturing, chemical blending and environmental protection. Special attention is paid to importance on independent contractors represented by the Small Explorers and Producers Association of Canada (SEPAC), their ability to develop or adopt new technology and to accommodate the demands of constantly changing price levels and increasingly higher expectations in terms of social responsibility, productivity and competitiveness, as well as environmental performance. As an example, the article describes the career of Robert Tessari, founder and president of Tesco Corporation, a drilling company operating in some 40 countries, who aims to automate drilling to the point where rig crews are pared to teams of two or three experts directing machinery from computer consoles. That he is well on the way of achieving his objectives is illustrated by his contributions to the development of a new generation of bits, tools and procedures known as the &apos;case drilling&apos; process which simultaneously uses the same steel tubing to make the holes into oil and gas-bearing formations and line them for production, and in so doing cut 25 to 30 per cent off the time required to drill a well and bring it to production.

    Bovard, P.; Grauby, A.

    The problems of medium protection against radioactive contamination hazards have led the Commissariat a l&apos;Energie Atomique--Service de Controle des Radiations et de Genie Radioactif to study the behavior of ions in soils. There are many theoretical researches and laboratory studies on the movement of radioelements in soil. But, with the difficulties for obtaining a similar result in field, we have developed a simple direct method of in place soil contamination. However, a principal drawback remains, the necessity to extrapolate from one or two reduced size samples to a large area. This is all the problem of sampling, which is not specific of our method. However, a choice justified by classical data, let us obtain a sufficient number of results and an accuracy which is suitable.

    In Denmark energy consultancy (demand side management activities (DSM)) took its first steps in the middle of the 80&apos;ies. The energy consultancy was built up around the Danish electric utilities on which the Danish government imposed the implementation of energy savings for funds collected through the electricity bill (approx. 0.0006 DKK/kWh corresponding to approx. 0.001 ECU). The electric utilities trained energy consultants who specialised in visiting industrial enterprises and counselling on energy consumption, primarily focusing on auxiliary systems like lighting, compressed air, ventilation and heating. Within these areas large savings could be obtained because each company was focusing on the actual production but also because the cost of energy was a fraction of the total costs. (orig.)

    The presentation outlines and Accompanying Measure with the FP 5 to develop an web based EUropean Sustainable Land and GRoundwater Management Information System information system (EUGRIS). The management of contaminated land and groundwater requires an interdisciplinary approach and a considerable amount of supporting technical information and knowledge. EUGRIS will provide a generally available comprehensive and overarching information and innovation resource, to support both research and practical contaminated land and groundwater management. EUGRI is a gateway to provide a &apos;one stop shop&apos; for information provided by research projects, legislation, standards, best practice and other technical guidance and policy/regulatory publications from the EC, participating Member and Accession States and from various international networks dealing with groundwater and land management issues. Different types of user can access information through different windows according to their needs. EUGRIS will provide its visitors with summary information (digests) and links to sources of more detailed and/or original information in a scaleable holistic and contexturally meaningful way. EUGRIS is being built in three stages: the design of the information system, the development of its software implementation, and the population of the system with information. The presentation is focussed on the concept of the development of the information system with the individual work packages. In the second part of the lecture in particular the work procedures are presented for the content wise replenishment by EUGRIS. The data collation for the proven pilot countries and the production of a European research data base, which opens contents and results of European-wide locked and current projects, form the emphasis thereby.

    To evaluate multiparametric-MRI (mpMRI) derived histogram textural-analysis parameters for detection of transition zone (TZ) prostatic tumour. Sixty-seven consecutive men with suspected prostate cancer underwent 1.5T mpMRI prior to template-mapping-biopsy (TPM). Twenty-six men had &apos;significant&apos; TZ tumour. Two radiologists in consensus matched TPM to the single axial slice best depicting tumour, or largest TZ diameter for those with benign histology, to define single-slice whole TZ-regions-of-interest (ROIs). Textural-parameter differences between single-slice whole TZ-ROI containing significant tumour versus benign/insignificant tumour were analysed using Mann Whitney U test. Diagnostic accuracy was assessed by receiver operating characteristic area under curve (ROC-AUC) analysis cross-validated with leave-one-out (LOO) analysis. ADC kurtosis was significantly lower (p < 0.001) in TZ containing significant tumour with ROC-AUC 0.80 (LOO-AUC 0.78); the difference became non-significant following exclusion of significant tumour from single-slice whole TZ-ROI (p = 0.23). T1-entropy was significantly lower (p = 0.004) in TZ containing significant tumour with ROC-AUC 0.70 (LOO-AUC 0.66) and was unaffected by excluding significant tumour from TZ-ROI (p = 0.004). Combining these parameters yielded ROC-AUC 0.86 (LOO-AUC 0.83). Textural features of the whole prostate TZ can discriminate significant prostatic cancer through reduced kurtosis of the ADC-histogram where significant tumour is included in TZ-ROI and reduced T1 entropy independent of tumour inclusion.

    In the European radiological early warning system about 5500 stationary sensors are actually implemented that measure continuously the local dose rate. Alongside several hundred air dust collecting systems attribute to the measurement of airborne radioactivity. The local dose rates are transmitted hourly to a central data base that is operated on behalf of the EU commission. In significantly larger time intervals the measured data of the airborne radioactivity are transmitted. In case of a cross-border radiological accident these data are the basis for recommendations given by the EU commission to the member states for national counter measures. The focus of the project &apos;&apos;Metrology for radiological early warning networks in Europe&apos;&apos; is an improvement of the metrological quality and harmonization these data and the development of improved measuring systems and evaluation methods.

Concerning the first point, it can be noticed that nowadays, mobile platforms are located in great offshore where water depths are of about 2400 m. In the second point is particularly detailed what 4D is, what it can do, what the primary conditions for it works are and how it costs. The third point is the more particularly detailed in this section (15 pages). At first an introduction indicates why Iran has to call to international petroleum investors, what the current problems of Iran are, what Iran has to do to attract foreign investment and technology and what the challenges to foreign companies are. Then the two operating plans: &apos;SIRRI&apos; and &apos;DOROOD&apos; are exposed into details. A synthesis of these plans, called of &apos;Buy Back&apos;, (production, investment, refund) is given as well as their advantages and disadvantages. (O.M.)

  17. The Effect of a High-Fat Diet on Brain Plasticity, Inflammation and Cognition in Female ApoE4-Knockin and ApoE-Knockout Mice.

    Carola I F Janssen

    Full Text Available Apolipoprotein E4 (ApoE4, one of three common isoforms of ApoE, is a major risk factor for late-onset Alzheimer disease (AD. ApoE-deficient mice, as well as mice expressing human ApoE4, display impaired learning and memory functions and signs of neurodegeneration. Moreover, ApoE protects against high-fat (HF diet induced neurodegeneration by its role in the maintenance of the integrity of the blood-brain barrier. The influence of a HF diet on the progression of AD-like cognitive and neuropathological changes was assessed in wild-type (WT, human ApoE4 and ApoE-knockout (ApoE-/- mice to evaluate the modulatory role of ApoE in this process. From 12 months of age, female WT, ApoE4, and ApoE-/- mice were fed either a standard or a HF diet (19% butter, 0.5% cholate, 1.25% cholesterol throughout life. At 15 months of age mice performed the Morris water maze, evaluating spatial learning and memory. ApoE-/- showed increased spatial learning compared to WT mice (p = 0.009. HF diet improved spatial learning in WT mice (p = 0.045, but did not affect ApoE4 and ApoE-/- mice. Immunohistochemical analyses of the hippocampus demonstrated increased neuroinflammation (CD68 in the cornu ammonis 1 (CA1 region in ApoE4 (p = 0.001 and in ApoE-/- (p = 0.032 mice on standard diet. HF diet tended to increase CD68 in the CA1 in WT mice (p = 0.052, while it decreased in ApoE4 (p = 0.009, but ApoE-/- remained unaffected. A trend towards increased neurogenesis (DCX was found in both ApoE4 (p = 0.052 and ApoE-/- mice (p = 0.068. In conclusion, these data suggest that HF intake induces different effects in WT mice compared to ApoE4 and ApoE-/- with respect to markers for cognition and neurodegeneration. We propose that HF intake inhibits the compensatory mechanisms of neuroinflammation and neurogenesis in aged female ApoE4 and ApoE-/- mice.

    Serum amyloid P conpoent (SAP), a member of the pentraxin family, interact with pathogens and cell debris to promote their removal by macrophages and neutrophils and is co-localized with atherosclerotic plaques in patients. However, the exact mechanism of SAP in atherogenesis is still unclear. We investigated whether SAP influence macrophage recruitment and foam cell formation and ultimately affect atherosclerotic progression. we generated apoE(-/-); SAP(-/-) (DKO) mice and fed them western diet for 4 and 8 weeks to characterize atherosclerosis development. SAP deficiency effectively reduced plaque size both in the aorta (p = 0.0006 for 4 wks; p = 0.0001 for 8 wks) and the aortic root (p = 0.0061 for 4 wks; p = 0.0079 for 8wks) compared with apoE(-/-) mice. Meanwhile, SAP deficiency inhibited oxLDL-induced foam cell formation (p = 0.0004) compared with apoE(-/-) mice and SAP treatment increases oxLDL-induced foam cell formation (p = 0.002) in RAW cells. Besides, SAP deficiency reduced macrophages recruitment (p = 0.035) in vivo and in vitro (p = 0.026). Furthermore, SAP treatment enhanced CD36 (p = 0.007) and FcγRI (p = 0.031) expression induced by oxLDL through upregulating JNK and p38 MAPK phosphorylation whereas specific JNK1/2 inhibitor reduced CD36 (p = 0.0005) and FcγRI (P = 0.0007) expression in RAW cell.

    Full Text Available Radioterapia é uma importante alternativa de tratamento curativo em pacientes com câncer do pulmão não de pequenas células. Entretanto, pulmões são muito sensíveis à radiação e isto aumenta a importância em se delimitar o volume a ser irradiado com precisão. Ultimamente, a tomografia por emissão de pósitron (PET e a tomografia computadorizada (TC são feitas de forma combinada, e a literatura sugere que seu impacto no planejamento da radioterapia é significativo. Ao se utilizar exames de PET/TC no planejamento da radioterapia é importante reconhecer e adaptar-se às diferenças entre os equipamentos de diagnóstico e de tratamento. Este texto discute alguns dos problemas técnicos que devem ser resolvidos quando se incorpora PET no planejamento radioterápico.Radiation therapy represents an important alternative for curative treatment of patients with nonsmall cell lung cancer. However, an accurate definition of the volume to be irradiated becomes even more important, considering that lungs are highly sensitive to radiation. Most recently, combined FDG-PET/CT scan has been utilized, and the literature reports its significant role in the planning of radiation therapy, since it seems to influence the target-volume delineation in cases of lung cancer. Differences between diagnostic and treatment equipments must be taken into consideration when FDG-PET/CT scan is utilized in the planning of radiation therapy. The present study discusses some of the many technical problems that must be solved when PET is incorporated into the planning of radiation therapy for non-small cell lung cancer.

    The &apos;Bribe&apos; and &apos;Drum&apos; Affairs and suspected proliferation in connection with Transnuklear GmbH public around the turn of 1987/88. Many members of the press wished them to speed up the process of opting out of nuclear power. However, none of the accusations specifically related to nuclear power leveled at that time turned out to be tenable. Instead, all violations of the law which had been detected could have been punished in the same way as in any other branch of industry. As a consequence, the impacts arising to regulatory structures in the nuclear sector, especially the measures taken by the Federal Government, may be considered to have been unjustified in scope. The TN Affair and the associated litigation has caused a great deal of confidence in nuclear power to be lost, which now has to be reclaimed by purposeful public relations efforts. (orig.).

    To expand the search for central pulmonary arteries in six patients with absence of cardiac-pulmonary continuity, computerized axial tomography (CAT) of the chest was performed. The CAT scans were compared with previous arteriograms and pulmonary vein wedge angiograms. Three patients with type IV truncus arteriosus were studied, and none had a central, right or left pulmonary artery on CAT scan. However, two patients with tetralogy of Fallot with pulmonary atresia and a patent ductus arteriosus to the right lung demonstrated the presence of a left pulmonary artery. In addition, one child with truncus arteriosus with &apos;'absent'&apos; left pulmonary artery demonstrated a left pulmonary artery on the CAT scan. The CAT scan may therefore enhance our ability to search for disconnected pulmonary arteries in children with complex cyanotic congenital heart disease.

  6. Metrology for the radiological early warning system in Europe. The &apos;'MetroERM'&apos; project

    International Nuclear Information System (INIS)

    In the European radiological early warning system about 5500 stationary sensors are actually implemented that measure continuously the local dose rate. Alongside several hundred air dust collecting systems attribute to the measurement of airborne radioactivity. The local dose rates are transmitted hourly to a central data base that is operated on behalf of the EU commission. In significantly larger time intervals the measured data of the airborne radioactivity are transmitted. In case of a cross-border radiological accident these data are the basis for recommendations given by the EU commission to the member states for national counter measures. The focus of the project &apos;&apos;Metrology for radiological early warning networks in Europe&apos;&apos; is an improvement of the metrological quality and harmonization these data and the development of improved measuring systems and evaluation methods.

    In this paper we consider the dynamics of a massive spinor field in the background of the acoustic black hole spacetime. Although this effective metric is acoustic and describes the propagation of sound waves, it can be considered as a toy model for the gravitational black hole. In this manner, we study the properties of the dynamics of the fermion field in this &apos;'gravitational'&apos; rotating black hole as well as the vortex background. We compute the differential cross section through the use of the partial wave approach and show that an effect similar to the gravitational Aharonov-Bohm effect occurs for the massive fermion field moving in this effective metric. We discuss the limiting cases and compare the results with the massless scalar field case. (orig.)

    Radiotherapy techniques for esophageal cancer were compared using a three-dimensional planning system. We studied the following treatment techniques used for a patient with squamous cell carcinoma of the middle third of the esophagus: two antero-posterior and two latero-lateral parallel opposed fields, three fields (&apos;Y&apos; and &apos;T&apos;), and four fields (&apos;X&apos;). Dose-volume histograms were obtained considering spinal cord and lungs as organs at risk. Analysis was performed comparing doses in these organs as recommended by the Normal Tissue Complication Probability (NTCP) and Tumor Control Probability (TCP). When only the lungs were considered the best technique was two antero-posterior parallel opposed fields. The spinal cord was best protected using latero-lateral fields. We suggest the combination of at least two treatment techniques: antero-posterior fields with &apos;Y&apos; or &apos;T&apos; techniques, or latero-lateral fields in order to balance the doses in the lungs and the spinal cord. Another option may be the use of any of the three-field techniques during the whole treatment. (author)

  10. Iran&apos;s &apos;Risk-Taking&apos; in Perspective

    2008-07-01

    Assessing any state&apos;s intentions is a difficult undertaking - especially at a specific moment in time. When a state is considered hostile, its behaviour erratic, and its system opaque, what is difficult under normal circumstances becomes nearly impossible. It may thus often seem prudent to attribute the worst of intentions to such states, but this can create a self-fulfilling prophecy. Iran with its revolutionary pretensions, fiery rhetoric and nuclear ambitions, is a case in point, since it is particularly difficult to &apos;read&apos;. Located in the centre of a geo-politically sensitive and conflict-driven area, Iran is in a position to influence - positively or otherwise - the Persian Gulf, the Caucasus, the Middle East and South Asia. This influence may furthermore be expanding as a result of the weakening of Iraq and Lebanon, divisions among the Palestinians, and the more general rise of the Shi&apos;i across the broader region. Add to this the ambiguous aims of Iran&apos;s nuclear programme and the shadow this has already thrown across the region, and the need to assess Iran&apos;s intentions accurately appears crucial. Here, Iran&apos;s past behavior may provide some help, especially when it comes to Iran&apos;s proclivity for risk taking - provided the acquisition of a nuclear capability does not alter Iran&apos;s intentions or behavior so as to make the past irrelevant. Some commentators believe that Iran&apos;s ideology and past behaviour suggest that a nuclear-capable Iran will be inclined to take on a high level of risk, without concern for the potential costs of this recklessness, and that Iran may perhaps even welcome the risks involved. By contrast, the recent National Intelligence Estimate (NIE), a composite of US intelligence agency estimates, has concluded that Iran&apos;s &apos;decisions are guided by a cost-benefit approach&apos; and therefore &apos;may be more vulnerable to influence&apos; than they had previously (i.e.2005) judged.

    A new interpretation of Maxwell&apos;s electromagnetic theory of light is proposed, namely that the ambient Coulomb field is the medium (Maxwell&apos;s ether) of the electromagnetic radiation fields (Maxwellian waves). This investigation implies an incompleteness of the experimental foundations of the principle of special relativity, and suggests how this principle could be tested more fully. The beginning of an attempt to shape this re-interpretation in the form of an alternative theory is outlined.

    Apolipoprotein E4 (apoE4), the most prevalent genetic risk factor for Alzheimer's disease (AD), is associated with neuronal and vascular impairments. The retina, which is as an extension of the central nervous system (CNS), is a particularly suitable model for studying developmental and functional aspects of the neuronal and vascular systems. This study investigates the apoE4-dependent developmental effects on the retinal vasculature and neuronal systems and on the levels of apoE and the vascular endothelial growth factor (VEGF) in the retina. This was performed utilizing retinas of 4, 7, 12, and of 120-day-old human-apoE4-targeted replacement mice and of corresponding mice that express the AD benign isoform, apoE3. The results obtained revealed retinal vascular pathology in the apoE4 mice, which started on the early post-natal days. This includes transient increase in vascular branching, and vascular buds which are round vascular elements representing sprouting or retracting vessels. These effects peaked and ended during the neonatal period. Examination of the synaptic system utilizing the pre-synaptic marker synaptophysin revealed a significant decrease of retinal synaptic density in the apoE4 mice, which was detectable by post-natal day 12 (P12). These morphological changes are associated with neonatal age-dependent elevation in the apoE levels in both apoE3 and apoE4 retinas which is more profound in the apoE4 mice and a corresponding increase in VEGF levels, which is less profound in the apoE4 mice. Additionally, we observed lower levels of retinal VEGF in the apoE4 mice compared to the apoE3 mice retinas on P12. These results show that apoE4 has a transient vascular effect during retinal development that ends in the neonatal period, which is accompanied by a synaptic effect that begins at the end of the neonatal period. These findings show that the apoE4 genotype can have distinct developmental effects on both the retinal vasculature and on neurons and

  15. ApoE4-specific Misfolded Intermediate Identified by Molecular Dynamics Simulations.

    Full Text Available The increased risk of developing Alzheimer's disease (AD is associated with the APOE gene, which encodes for three variants of Apolipoprotein E, namely E2, E3, E4, differing only by two amino acids at positions 112 and 158. ApoE4 is known to be the strongest risk factor for AD onset, while ApoE3 and ApoE2 are considered to be the AD-neutral and AD-protective isoforms, respectively. It has been hypothesized that the ApoE isoforms may contribute to the development of AD by modifying the homeostasis of ApoE physiological partners and AD-related proteins in an isoform-specific fashion. Here we find that, despite the high sequence similarity among the three ApoE variants, only ApoE4 exhibits a misfolded intermediate state characterized by isoform-specific domain-domain interactions in molecular dynamics simulations. The existence of an ApoE4-specific intermediate state can contribute to the onset of AD by altering multiple cellular pathways involved in ApoE-dependent lipid transport efficiency or in AD-related protein aggregation and clearance. We present what we believe to be the first structural model of an ApoE4 misfolded intermediate state, which may serve to elucidate the molecular mechanism underlying the role of ApoE4 in AD pathogenesis. The knowledge of the structure for the ApoE4 folding intermediate provides a new platform for the rational design of alternative therapeutic strategies to fight AD.

    The authors isolated and sequenced a cDNA clone of the human gene encoded by the 5&apos; half of the ret transforming gene. The nucleotide sequence indicates that it encodes a protein with &apos;'finger'&apos; structures which represent putative metal- and nucleic acid-binding domains. Transcriptions of this gene was detected at high levels in a variety of human and rodent tumor cell lines, mouse testis, and embryos. In addition, a unique transcript was observed in testis RNA. When the expression of the unique transcript was examined at different stages of spermatogenesis, a striking increase in mRNA levels accompanied progression from meiotic prophase pachytene spermatocytes to postmeiotic round spermatids. This finger-containing gene may thus function in male germ cell development.

    Despite the important role of apolipoprotein E (apoE) secretion from astrocytes in brain lipid metabolism and the strong association of apoE4, one of the human apoE isoforms, with sporadic and late onset forms of Alzheimer's disease (AD) little is known about the regulation of astrocytic apoE. Utilizing annotated chemical libraries and a phenotypic screening strategy that measured apoE secretion from a human astrocytoma cell line, inhibition of pan class I histone deacetylases (HDACs) was identified as a mechanism to increase apoE secretion. Knocking down select HDAC family members alone or in combination revealed that inhibition of the class I HDAC family was responsible for enhancing apoE secretion. Knocking down LXRα and LXRβ genes revealed that the increase in astrocytic apoE in response to HDAC inhibition occurred via an LXR-independent pathway. Collectively, these data suggest that pan class I HDAC inhibition is a novel pathway for regulating astrocytic apoE secretion.

    Toxoplasma deprives host neuron cells from cholesterol and leads to its ability to potentiate dementia. ApoE intermediates neuronal transmission of cholesterol, which is a key constituent for axonal development, redesigning occasions that are important for education and synaptic arrangement, development of memory and repair of neuron. The aim of this work is to investigate the effect of ApoE genotypes on dementia associated with neurodegeneration in latent Toxoplasma gondii in elderly population. This study comprised: 133 patients with dementia (78 were positive for toxoplasma IgG and 55 were negative) and 95 subjects as control group without dementia (30 were positive for toxoplasma IgG and 65 were negative). All of them were subjected to a cognitive assessment, T. gondii seropositivity (ELISA) and determination of ApoE allelic forms (PCR). The ApoE genotype distribution shows that the most predominant genotype is ApoE3/3 and the most widely recognized allele is E3. Both patients and control were further divided into Toxoplasma IgG positive group (n=108) and Toxoplasma IgG negative group (n=120).

    In this work it was possible to analyze the perception of risks associated with existing processes in the high-dose rate brachytherapy and teletherapy using linear accelerators of radiotherapy services in the metropolitan area of Rio de Janeiro, through the combined use of two proposed methods: FMECA and risk matrix, using a general analysis and other more specific ones. The database software (SEVRRA) was used to identify possible existing processes in radiotherapy services (brachytherapy and teletherapy) and to classify the sequence of events in risk levels. The risk levels were analyzed at each stage and sub-stage, present in the treatment of patients undergoing high dose rate gynecological intracavitary brachytherapy and teletherapy treatments with the use of linear accelerators applying electron or photon beams in order to establish recommendations to the risks of highest priority for each case. The results show that although the procedure of high dose rate brachytherapy be automated and less susceptible to errors or failures, daily, one can still find considerable amounts of processes with worrying levels of risk perception. The processes that are more subject to radiological accident risks was associated with procedures, for of which the majority of the failures record and planning step of the treatment. The controls analyzed showed low efficiency, warning of the need to seek and implement new more efficient controls in routine brachytherapy for each participant service. About teletherapy procedure it was found that most of the failures were related to the registration and planning of treatment and equipment stages. The controls analyzed to teletherapy showed a poor result with a first type of analysis performed by suggesting a new type of more appropriate analysis. With a second type of analysis, these controls could be better analyzed and showed an order of importance according to a percentage of efficiency. Controls such as &apos;Double-check&apos;, &apos

    The microbial catabolic activity of biological reactors can be increased by up to 75% through external stimulation with intermittent stress loads at intervals of several minutes. Under these process conditions, the &apos;&apos;biological resonance&apos;&apos; phenomenon determines the system and leads to an increased synthesis of enzymes. In addition to computer simulations, experiments with activated sludge were carried out in a 10-litre bioreactor. By modulating the stress intervals, a permanent increase in catabolic activity of about 60% was achieved during these experiments. By relying on the &apos;&apos;biological resonance&apos;&apos; phenomenon, the required reaction volume of biological treatment units can probably be reduced by up to 40%. (orig.)

But energy represents a tool by which society can be shaped; a device by which the standared of living and the very nature of the national lifestyle can be controlled, modified, amplified, or reduced. Two examples examined to show how energy shapes social order and human life are the women&apos;s movement and the desire to live in the Sunbelt. Five phenomena are then examined to point out the desire to restrain the nation&apos;s rampant pursuit of a higher standard of living, as opposed to the more subjective and seemingly more desirable goal of a better quality of life: the civil rights movement; the environmental movement; the Vietnam War; the Watergate scandal; and the assumption that prosperity at today&apos;s level is irreducible, concrete, and not subject to diminution. The &apos;&apos;new class&apos;&apos; is essentially made up of those educated in the liberal arts, divorced from an understanding of the mechanics of free-enterprise institutions and of the sicences. The antagonistic view of the new class of corporations and its assault on established institutions are noted. Energy companies are frustrated in telling their story, but the story that must be told is not the story of how excellently the energy sector has performed, but the story of how a new breed of Americans is seeking to remake America in its own image without the rest being aware of what is going on.

  13. Crisis - Weisskopf&apos;s view

    &apos;We are facing a crisis, not only in particle physics but in the whole of fundamental science&apos;, said Victor Weisskopf, doyen of quantum physics, during his traditional summer CERN stopover. &apos;Basic science - science for its own sake - and especially high energy physics, is really in danger.&apos; As well as explaining how this has come about, the former CERN Director General (1961-5) proposed action to reverse the trend. Rather than dividing science into the conventional &apos;big&apos; and &apos;small&apos; camps, he slices across another axis. On one hand there is obviously applicable &apos;terrestrial science&apos; - biology, medicine, solid state, much of the nuclear sector, nonlinear behaviour, chaos,....all directly connected with processes that happen on Earth. On the other there is &apos;cosmic science&apos; - astronomy, astrophysics, particle physics and some of the nuclear sector - addressing deeper issues, not attainable naturally on this planet at all, and where applications are less immediately obvious. (This classification is not completely watertight - even cosmic science can, and does, foster immediate spinoff, Weisskopf points out, citing Georges Charpak&apos;s detector work.) Tracing the evolution of science in this century, Weisskopf sees the rapid evolution of American influence in the 1930s as a turning point. Before then, the United States had not been in the front line, and it had been important for US researchers to spend some time in Europe

    Since the INPRO Collaborative Project on Proliferation Resistance and Safeguardability Assessment Tools (PROSA) was launched in 2011, Member State experts have worked with the INPRO Section and the IAEA Department of Safeguards to develop a revised methodology for self-assessment of sustainability in the area of proliferation resistance of a nuclear energy system (NES). With the common understanding that there is &apos;&apos;no proliferation resistance without safeguards&apos;&apos; the revised approach emphasizes the evaluation of a new &apos;User Requirement&apos; for &apos;'safeguardability'&apos;, that combines metrics of effective and efficient implementation of IAEA Safeguards including &apos;'Safeguards-by-Design'&apos; principles. The assessment with safeguardability as the key issue has been devised as a linear process evaluating the NES against a &apos;&apos;Basic Principle&apos;&apos; in the area of proliferation resistance, answering fundamental questions related to safeguards: 1) Do a State&apos;s legal commitments, policies and practices provide credible assurance of the exclusively peaceful use of the NES, including a legal basis for verification activities by the IAEA? 2) Does design and operation of the NES facilitate the effective and efficient implementation of IAEA safeguards? To answer those questions, a questionnaire approach has been developed that clearly identifies gaps and weaknesses. Gaps include prospects for improvements and needs for research and development. In this context, the PROSA approach assesses the safeguardability of a NES using a layered &apos;&apos;Evaluation Questionnaire&apos;&apos; that defines Evaluation Parameters (EP), EP-related questions, Illustrative Tests and Screening Questions to present and structure the evidence of findings. An integral part of the assessment process is Safeguards-by-Design, the identification of potential diversion, misuse and concealment strategies (coarse diversion path

    The prevention and treatment of radiotherapy-induced oral mucositis have still not been fully defined. The current study thus involved a literature search aimed at identifying preventive and therapeutic measures in relation to oral mucositis in patients submitted to radiotherapy, analyzing the level of evidence in the selected studies, identifying which indications for prevention and treatment in the literature pertain to the field of nursing, and critically analyzing the results and their implications for nursing care. This was a systematic literature survey without a meta analysis, consulting the following databases: BIREME, Medline, CancerLit, Scirus, CAPES, Free medical journal, High wire press, SCIELO, and Medscape, from 2000 to 2005. According to observations, nursing care was capable of improving patient&apos;s quality of life, promoting education of patients, implementing and supervising oral care programs, and providing guidance on hygiene, prevention, and treatment of oral mucositis, including pain management. However, no Brazilian nursing publications were found on the subject. Research and publications focusing on nursing experience in the prevention and treatment of radiotherapy-related oral mucositis and the implications for patients and nurses are important to provide evidence-based nursing guidelines.

    Introduction: Cancer is among the world&apos;s leading chronic non communicable diseases and, by 2030, an increase in the incidence of 54% in relation to 2015 is expected. This increase requires strategies and public policies aimed at meeting the demands for treatment, especially radiation therapy, since it involves specific equipment and human resources. Objectives: To present the current scenario of radiotherapy in Brazil, its structural and human resources, as well as to estimate the radiotherapy scenario for the country in 2030. Method: This is a descriptive study carried out based on theoretical reference and conformed from Current and projected population estimates, banks of official information systems and professional sites, and in legislation and standards that normalize and license the theme in Brazil. Result: The results obtained show that the deficit in July of 2015 in Brazil is 255 radiotherapy and human resources services of 387 radiotherapists, 546 physical doctors and 425 production supervisors. For the year 2030, the estimated deficit is 198 radiotherapy and human resources services of 235 physicians and 114 production supervisors. Conclusion: Population aging and the consequent increase in non-communicable chronic diseases, such as cancer, require public health services to plan demands for treatment. The current and projected deficit of radiotherapy in Brazil signals the urgency of strategies and public policies capable of meeting the needs presented.

    Many of the planned upgrading measures of Ukrainian VVER plants and of the unique Armenian power plant (Medzanor) are financed by the European Union (EU) through the TACIS program. The &apos;&apos;2+2&apos;&apos; approach implies a deep collaboration between Ukrainian or Armenian regulatory authorities, local operating organizations and EU organizations. This approach allows: - a smooth adaptation of western technologies to VVERs, - a comprehensive checking of Ukrainian, Armenian and western regulatory requirements, and - the transfer of know-how to the Ukrainian and Armenian organizations. This report presents the principles applied for &apos;&apos;2+2&apos;&apos; approach as well as a summary of the main recommendations given in the framework of the licensing process.

    The superconducting proximity effect strongly modifies the local density of states in chaotic Josephson junctions. Recently we found that besides the well-known minigap a secondary gap appears just below the superconducting gap edge Δ in the limit of a large Thouless energy E{sub Th} >or similar Δ. To check the universality of this novel gap phenomenon we study the effect of nonideal contacts and show that the &apos;'smile'&apos;-gap crucially depends on the transmission eigenvalue distribution. In a next step we use the random matrix method to investigate the &apos;'smile'&apos;-gap. This allows us to approach the statistics of Andreev levels, going beyond the quasiclassical Greens function method. It turns out that the hard gap edge softens similar to what is already known from the minigap.

    In order to gain a more comprehensive understanding of the aetiology of apolipoprotein E4 genotype-cardiovascular disease (CVD) associations, the impact of the apoE genotype on the macrophage inflammatory response was examined. The murine monocyte-macrophage cell line (RAW 264.7) stably transfected to produce equal amounts of human apoE3 or apoE4 was used. Following LPS stimulation, apoE4-macrophages showed higher and lower concentrations of tumour necrosis factor alpha (pro-inflammatory) and interleukin 10 (anti-inflammatory), respectively, both at mRNA and protein levels. In addition, increased expression of heme oxygenase-1 (a stress-induced anti-inflammatory protein) was observed in the apoE4-cells. Furthermore, in apoE4-macrophages, an enhanced transactivation of the key redox sensitive transcription factor NF-kappaB was shown. Current data indicate that apoE4 macrophages have an altered inflammatory response, which may contribute to the higher CVD risk observed in apoE4 carriers.

    The Anadenathera macrocarpa, Schinus molle, Hymenaea courbaril, Cariniana legalis, Solidago microglossa and Stryphnodendron barbatiman, were collected &apos;&apos;in natura&apos;&apos; samples (leaves, flowers, barks and seeds) from different commercial suppliers. The pharmaco-active compounds in ethanolic extracts had been made by the Mato Grosso Federal University (UFMT). The energy-dispersive x-ray fluorescence (ED-XRF) spectrometry was used for the elemental analysis in different parts of the plants and respective ethanolic extracts. The Ca, Cl, Cu, Fe, K, Mg, Mn, Na, Ni, P, Rb, S, Sr and Zn concentrations were determined by the fundamental parameters method. Some specimens showed a similar inorganic profile for &apos;&apos;in natura&apos;&apos; and ethanolic extract samples and some ones showed a distinct inorganic profile. For example, the Anadenathera macrocarpa showed a similar concentration in Mg, P, Cu, Zn and Rb elements in &apos;&apos;in natura&apos;&apos; and ethanolic extract samples; however very different concentration in Na, S, Cl, K , Ca, Mn, Fe and Sr was observed in distinctive samples. The Solidago microglossa showed the K, Ca, Cl, S, Mg, P and Fe elements as major constituents in both samples, suggesting that the extraction process did not affect in a considerable way the &apos;&apos;in natura&apos;&apos; inorganic composition. The elemental composition of the different parts of the plants (leaves, flowers, barks and seeds) has been also determined. For example, the Schinus molle specimen showed P, K, Cl and Ca elements as major constituents in the seeds, Mg, K and Sr in the barks and Mg, S, Cl and Mn in the leaves, demonstrating a differentiated elementary distribution. These inorganic profiles will contribute to evaluate the quality control of the Brazilian herbaceous trade and also will assist to identify which parts of the medicinal plants has greater therapeutic effect.

    &apos;Green&apos; building materials may be defined as being made of materials and by processes that have low impact on the environment. Linoleum is an example of a sustainable &apos;green&apos; building material. It is durable, easy to repair, is inherently antimicrobial, and has low-cost maintenance. Unlike most other floor coverings, linoleum has naturally occurring anti-static properties, making it easy to clean, since dust and dirt will not adhere to it. The ingredients in linoleum are linseed oil, resin, limestone, wood flour, pigments and jute, all obtainable from natural sources. Vibrant colours for the flooring are created by using organic pigments with no heavy metals such as lead or calcium which, consequently, pose no threat to the environment. Linoleum is also biodegradable. It can be put into a landfill, where it will decompose; in some parts of the world it is incinerated to produce electricity. When used as feedstock for electricity, used linoleum products have an energy content of 18.6 MJ/kg, which is equivalent to coal. As no toxic or corrosive gases are released, the need for gas purification is avoided.

    The spectral characters of an acupuncture point named &apos;Waiqiu&apos; in superficial fascia tissue have been studied by photoluminescence (PL) spectroscopy under the excitation of 457.9 nm. The PL around &apos;Waiqiu&apos; acupuncture point consists of two sub-bands resulting from the flavin adenine dinucleotide (FAD) and phospholipids, and the porphyrins (including purine, isoxanthopterin and tryptophan), respectively. More emission due to FAD and phospholipids is found inside the acupuncture effect area of &apos;Waiqiu&apos; than its marginal or outside acupuncture regions. The ratio of emission intensity of FAD and phospholipids to one of porphyrins gradually decreases along the direction away from the center of the acupuncture point. It implies that the component proportion changes between FAD, phospholipids and porphyrins around the &apos;Waiqiu&apos; acupuncture point. We suggest that there might be a certain relationship between redox function of FAD and &apos;Waiqiu&apos; acupuncture effect.

    Mutations in Amyloid β Precursor Protein (APP) and in genes that regulate APP processing--such as PSEN1/2 and ITM2b/BRI2--cause familial dementia, such Familial Alzheimer disease (FAD), Familial Danish (FDD) and British (FBD) dementias. The ApoE gene is the major genetic risk factor for sporadic AD. Three major variants of ApoE exist in humans (ApoE2, ApoE3, and ApoE4), with the ApoE4 allele being strongly associated with AD. ITM2b/BRI2 is also a candidate regulatory node genes predicted to mediate the common patterns of gene expression shared by healthy ApoE4 carriers and late-onset AD patients not carrying ApoE4. This evidence provides a direct link between ITM2b/BRI2 and ApoE4. To test whether ApoE4 and pathogenic ITM2b/BRI2 interact to modulate learning and memory, we crossed a mouse carrying the ITM2b/BRI2 mutations that causes FDD knocked-in the endogenous mouse Itm2b/Bri2 gene (FDDKI mice) with human ApoE3 and ApoE4 targeted replacement mice. The resultant ApoE3, FDDKI/ApoE3, ApoE4, FDDKI/ApoE4 male mice were assessed longitudinally for learning and memory at 4, 6, 12, and 16-17 months of age. The results showed that ApoE4-carrying mice displayed spatial working/short-term memory deficits relative to ApoE3-carrying mice starting in early middle age, while long-term spatial memory of ApoE4 mice was not adversely affected even at 16-17 months, and that the FDD mutation impaired working/short-term spatial memory in ApoE3-carrying mice and produced impaired long-term spatial memory in ApoE4-carrying mice in middle age. The present results suggest that the FDD mutation may differentially affect learning and memory in ApoE4 carriers and non-carriers. Copyright © 2015 Elsevier Inc. All rights reserved.

    In Multi-user PV hybrid grids (MSG) the adequate distribution of the available energy among the users and local organisation for new technology adoption are the main challenges for success of these systems. In the scope of the EU project MSG{sup 1} these challenges were tackled. An integrated socio-technical methodology was developed to bring into line social and technical aspects. It optimises each step of introduction of this technology on social level in order to improve user satisfaction and system performance. This reduces costs due to optimised sizing and reduction of failures due to inadequate user behaviour. A set of tools (&apos;'herramientas'&apos;) has been developed that support the planning and installation companies of MSGs. Based on this integrated approach the development of an intelligent &apos;&apos;energy dispenser / meter&apos;&apos; (patented) gives a solution to the energy distribution in the community by controlling the individual energy consumption behaviour of each user. The methodology was developed based on a detailed survey for several MSGs in Spain. This integrated approach was applied for the MSG in the rural village &apos;&apos;Cal Peraire&apos;&apos; providing electrical energy to 6 users. In this paper we present the first experience based on concrete data from the MSG installed. (orig.)

    Geo-technological investigation considerations of iron ore deposits within the Bakchar ore cluster are being carried out. The mineral and elemental composition of &apos;'loose'&apos; ores have been studied, embracing such important aspects as the distribution pattern of valuable and harmful impurities, the determination of element concentrators (such as vanadium, phosphate and sulphur) in basic minerals and the analysis of ore composition varaiation in volume ore cluster. Based on investigation results the mineral and elemental composition characteristic features of &apos;'loose'&apos; ores were defined. Although hydrogoethite was the basic identified ore mineral, such minerals as goethite, lepidocrocite, leptochlorite, siderite and hisingerite were also found. The deportment of calcium phosphate (anapaite) and phosphates of rare-earth elements (monazite, killarite), which are associated with the harmful impurity- phosphorous, are described. It has been defined that the ore constituent composition contains such persistent impurities as vanadium and manganese, the content of which is 0.35% and 0.03%, respectively. The &apos;'loose'&apos; ores are continuous in mineral composition, both in area and cross-section throughout the Bakchar ore cluster. Based on the sample element composition analysis the most perspective areas for further mineral processing could be: western with the fraction of 1....0.2mm. and eastern- fraction of 1...0.1mm

    In 192 sleep-healthy subjects (18 to 65 y) effects of nocturnal aircraft noise on sleep, stress, performance and subjective factors were investigated in 2240 nights under laboratory and field conditions. In the sleep lab, 112 volunteers were subjected to aircraft noise events by varying numbers and noise levels during 9 nights within a period of 13 nights. 16 further subjects served as control group (i.e. without any noise). 64 subjects were studied in the vicinity of Cologne-Bonn airport during 9 nights. Polysomnographical and acoustical recordings, determination of excretion rates of stress hormones from night urines, performance tests and questionnaires were conducted during all days for the assessment of nocturnal aircraft noise effects. By simultaneous recording of electrophysiological and acoustical data the probability of noise induced awakenings was estimated. Performance and most of psychological parameters did not show significant dose-effect relationships, whereas annoyance did. Epinephrine and norepinephrine did not change under aircraft noise, cortisol did change only in the lab. In the lab, a comparison between all noisy nights and noise-free baseline nights exhibited a non-significant 2-min. reduction of sleep and a 4-min. decrease of slow-wave sleep. In the field, awakenings caused by aircraft noise were detected above a threshold of 33 dB(A) &apos;&apos;at the sleeper&apos;s ear&apos;&apos;. All effects were much less pronounced in the field than in the lab. For the first time, precise dose-effect curves between maximum aircraft noise event levels and electrophysiologically detectable awakenings, and a threshold were empirically established. The results of these studies broadens the knowledge on aircraft noise induced sleep disturbances and immediate consequences for the next day. (orig.)

    At the Physikalisch-Technische Bundesanstalt, the National Metrology Institute of Germany, a new facility for measuring visual appearance-related quantities has been built up. The acronym ARGon{sup 3} stands for &apos;&apos;3D appearance robot-based gonioreflectometer&apos;&apos;. Compared to standard gonioreflectometers, there are two main new features within this setup. First, a photometric luminance camera with a spatial resolution of 28 {mu}m on the device under test (DUT) enables spatially high-resolved measurements of luminance and color coordinates. Second, a line-scan CCD-camera mounted to a spectrometer provides measurements of the radiance factor, respectively the bidirectional reflectance distribution function, in full V({lambda})-range (360 nm-830 nm) with arbitrary angles of irradiation and detection relative to the surface normal, on a time scale of about 2 min. First goniometric measurements of diffuse reflection within 3D-space above the DUT with subsequent colorimetric representation of the obtained data of special effect pigments based on the interference effect are presented.

    We analyse the quantum behaviour of the &apos;&apos;Little Sibling&apos;&apos; of the Big Rip singularity (LSBR) [1]. The quantisation is carried within the geometrodynamical approach given by the Wheeler-DeWitt (WDW) equation. The classical model is based on a Friedmann-Lemaître-Robertson-Walker Universe filled by a perfect fluid that can be mapped to a scalar field with phantom character. We analyse the WDW equation in two setups. In the first step, we consider the scale factor as the single degree of freedom, which from a classical perspective parametrises both the geometry and the matter content given by the perfect fluid. We then solve the WDW equation within a WKB approximation, for two factor ordering choices. On the second approach, we consider the WDW equation with two degrees of freedom: the scale factor and a scalar field. We solve the WDW equation, with the Laplace-Beltrami factor-ordering, using a Born-Oppenheimer approximation. In both approaches, we impose the DeWitt (DW) condition as a potential criterion for singularity avoidance. We conclude that in all the cases analysed the DW condition can be verified, which might be an indication that the LSBR can be avoided or smoothed in the quantum approach.

    Myxofibrosarcoma frequently shows curvilinear extensions of high T2 signal that also enhance on magnetic resonance imaging; these &apos;'tails'&apos; represent fascial extension of tumor at histopathological examination. This study was performed to determine whether the tail sign is helpful in distinguishing myxofibrosarcoma from other myxoid-containing neoplasms. The study group consisted of 44 patients with pathologically proven myxofibrosarcoma; the control group consisted of 52 patients with a variety of other myxoid-predominant tumors. Three musculoskeletal radiologists independently evaluated T2-weighted (and/or short-tau inversion recovery) and post-contrast MR images for the presence of one or more enhancing, high-signal intensity, curvilinear projections from the primary mass. Sensitivity and specificity for the diagnosis of myxofibrosarcoma were calculated for each reader. Interobserver variability was assessed with kappa statistic and percentage agreement. A tail sign was deemed present in 28, 30, and 34 cases of myxofibrosarcoma and in 11, 9, and 5 of the controls for the three readers respectively, yielding a sensitivity of 64-77 % and a specificity of 79-90 %. The interobserver agreement was moderate-to-substantial (kappa = 0.626). The tail sign at MRI is a moderately specific and sensitive sign for the diagnosis of myxofibrosarcoma relative to other myxoid-containing tumors. (orig.)

    Children&apos;s high awareness of environmental issues becomes evident in interviews with children and juveniles and in a number of studies carried out during the past few years. The authors draw a very sensitive picture of the terrifying world in which children may live, but they also show how children and juveniles can engage actively in conservation and environmental protection. They describe the many different groups of children and juveniles who use their initiative and imagination for protecting biotopes and species, bats and orchids, for reducing waste production and energy consumption, and increasingly frequently for protecting the tropical rainforests.

    Cardiac magnetic resonance (CMR) has increasingly proved to be a valuable diagnostic tool for evaluating patients with suspected myocarditis. The objective of this study was to evaluate the diagnostic value of functional and morphological parameters including tissue characterization in patients with &apos;&apos;infarct-like myocarditis&apos;&apos;. 43 patients with clinically verified cases of &apos;&apos;infarct-like myocarditis&apos;&apos; (median time to MRI scanning after admission for acute symptoms 3 days) and 35 control patients matched by age and sex were included in this retrospective case control study. In this study we used a 1.5 T MRI scanner conducting steady-state-free-precession sequences, T2-weighted imaging, T1-weighted imaging before and after contrast administration and late gadolinium enhancement sequences. According to the recommendations for CMR diagnosis of myocarditis (Lake Louise consensus criteria), a scan was positive for acute myocarditis if 2 of 3 CMR criteria were present. 30 % of the patients with &apos;&apos;infarct-like myocarditis&apos;&apos; had a reduced left ventricular ejection fraction, 11 % had an increased LV end-diastolic volume index and 35 % had an increased LV mass index. The sensitivity of wall motion abnormalities was 63 % with a regional distribution in 49 %. In 47 % of cases regional wall motion abnormalities were present in the lateral left ventricular segments. Pericardial effusions were discovered in 65 % of cases with a circular appearance in 21 % and focal manifestation in 44 %. The diagnostic sensitivity, specificity, and accuracy of CMR in patients with &apos;&apos;infarct-like myocarditis&apos;&apos; were 67 %, 100 % and 82 %, respectively. The LGE alone was the most sensitive test parameter with 86 %, providing a specificity of 100 % and accuracy of 92 %. Our study results can be applied to the subgroup of patients with &apos;&apos;infarct-like myocarditis&apos;&apos;, where we found that LGE alone was the

    Full text: The macroscopic haematuria is one of the most common reasons for visit in emergency urology clinic. Urology massive hematuria may be caused by inflammation, gallstones, trauma, benign and malignant tumors. The issue of &apos;Essential&apos; haematuria, typically of the upper urinary tract - one where it is not established cause, stands for decades. With the introduction of new diagnostic technologies - imaging and instrumentation, the share of &apos;Essential&apos; haematuria, decreased. The aim of the study was to investigate and establish the diagnostic value of venous and CT urography, MRI and ureterorenoscopy in case of chronic &apos;essential&apos; haematuria from the upper urinary tract by comparing their specificity and sensitivity. For a period of three years 214 patients were prospectively followed and hospitalized with macroscopic haematuria. All were examined with ultrasonography, radiography of the kidneys, ureters and bladder, cystoscopy. In 20 of the patients was excluded pathology of lower urinary tract as a cystoscope establish bleeding ureteral ostium / ostium, but diagnosis or direction of such a listed methods could not be found. Patients were subjected to IVP, then CT urography or MRI (in patients with elevated serum creatinine) and rigid ureterorenoscopy in this sequence and the results were analyzed. Of these 20 patients, 9 were diagnosed with malignancy, 4 - X-ray-negative lithiasis, eroded court, 4 - hemangioma changes or bleeding benign mucosa, 1 arterio-venous fistula, 2 were not finally diagnosed . 10 patients were diagnosed by IVP, which was confirmed by other methods (sensitivity 56.2%, specificity 75.7%). Both indicators were more robustly to cases of urothelial carcinoma pielon or ureter (respectively 66.9% and 84.4%). For CT urography and MRI the total sensitivity for detection of pathology was 85.8%, specificity 94.5%. In our series has revealed no statistically significant difference between the possibility of diagnosis

    In collaboration with Electricite de France (EdF), the French atomic energy commission (CEA), Schneider Electric and several laboratories of electrochemistry, Batscap, a daughter company of the Bollore group, has developed a new type of lithium-polymer battery for automotive applications. In this battery, each element is made of 4 films with a 100 {mu}m thickness winded together. The anode is a lithium metal foil, the electrolyte is a solid polymer film with several additives (lithium salts and others), and the cathode is a film of vanadium oxide-based polymer with carbon black as insertion compound. Finally, an &apos;intelligent&apos; aluminium metal film is used as collector. The use of these materials leads to an energy density of 150 Wh/kg and to a power density of 300 W/kg. The optimum temperature of utilisation is between 80 and 85 deg. C. The battery can be charged rapidly (50% during the first hour, the remaining 50% during 6 hours) and all the materials used are recyclable. Used in an electric-powered vehicle the battery has an autonomy of 200 to 300 km, a service life of 10 years (1000 cycles or 150000 km) and a temperature of use comprised between -20 and +60 deg. C. Its price is of about 1500 euros/vehicle. (J.S.)

    Full Text Available Abstract Background Apolipoprotein E (ApoE is a molecular scavenger in the blood and brain. Aberrant function of the molecule causes formation of protein and lipid deposits or "plaques" that characterize Alzheimer's disease (AD and atherosclerosis. There are three human isoforms of ApoE designated ε2, ε3, and ε4. Each isoform differentially affects the structure and function of the protein and thus the development of disease. Homozygosity for ApoE ε4 is associated with atherosclerosis and Alzheimer's disease whereas ApoE ε2 and ε3 tend to be protective. Furthermore, the ε2 form may cause forms of hyperlipoproteinemia. Therefore, introduction of ApoE ε3 may be beneficial to patients that are susceptible to or suffering from these diseases. Mesenchymal stem cells or multipotent mesenchymal stromal cells (MSCs are adult progenitor cells found in numerous tissues. They are easily expanded in culture and engraft into host tissues when administered appropriately. Furthermore, MSCs are immunosuppressive and have been reported to engraft as allogeneic transplants. In our previous study, mouse MSCs (mMSCs were implanted into the brains of ApoE null mice, resulting in production of small amounts of ApoE in the brain and attenuation of cognitive deficits. Therefore human MSCs (hMSCs are a promising vector for the administration of ApoE ε3 in humans. Results Unlike mMSCs, hMSCs were found not to express ApoE in culture; therefore a molecular screen was performed for compounds that induce expression. PPARγ agonists, neural stem cell conditioned medium, osteo-inductive media, dexamethasone, and adipo-inductive media (AIM were tested. Of the conditions tested, only AIM or dexamethasone induced sustained secretion of ApoE in MSCs and the duration of secretion was only limited by the length of time MSCs could be sustained in culture. Upon withdrawal of the inductive stimuli, the ApoE secretion persisted for a further 14 days. Conclusion The data

    We explore calculable models with low-energy supersymmetry where the flavor hierarchy is generated by quark and lepton compositeness, and where the composites emerge from the same sector that dynamically breaks supersymmetry. The observed pattern of Standard Model fermion masses and mixings is obtained by identifying the various generations with composites of different dimension in the ultraviolet. These &apos;single-sector&apos; supersymmetry breaking models give rise to various spectra of soft masses which are, in many cases, quite distinct from what is commonly found in models of gauge or gravity mediation. In typical models which satisfy all flavor-changing neutral current constraints, both the first and second generation sparticles have masses of order 20 TeV, while the stop mass is a few TeV. In other cases, all sparticles obtain masses of order a few TeV predominantly from gauge mediation, even though the first two generations are composite.

    This work presents an approach for neural network based transient identification which allows either dynamic identification or a &apos;don&apos;t know&apos; response. The approach uses two &apos;jump&apos; multilayer neural networks (NN) trained with the backpropagation algorithm. The &apos;jump&apos; network is used because it is useful to dealing with very complex patterns, which is the case of the space of the state variables during some abnormal events. The first one is responsible for the dynamic identification. This NN uses, as input, a short set (in a moving time window) of recent measurements of each variable avoiding the necessity of using starting events. The other one is used to validate the instantaneous identification (from the first net) through the validation of each variable. This net is responsible for allowing the system to provide a &apos;don&apos;t know&apos; response. In order to validate the method, a Nuclear Power Plant (NPP) transient identification problem comprising 15 postulated accidents, simulated for a pressurized water reactor (PWR), was proposed in the validation process it has been considered noisy data in order to evaluate the method robustness. Obtained results reveal the ability of the method in dealing with both dynamic identification of transients and correct &apos;don&apos;t know&apos; response. Another important point studied in this work is that the system has shown to be independent of a trigger signal which indicates the beginning of the transient, thus making it robust in relation to this limitation.

    Magnetic resonance imaging (MRI) was undertaken for two patients who suffered from severe cerebrovascular diseases and were clinically brain dead. The MRI system we used was Resona (Yokogawa Medical Systems, superconductive system 0.5 T) and the CT apparatus was Toshiba TCT-300. Initial CT and MRI were undertaken as soon as possible after admission, and repeated sequentially. After diagnosis of brain death, we performed angiography to determine cerebral circulatory arrest, and MRI obtained at the same time was compared with the angiogram and CT. Case 1 was a 77-year-old man who was admitted in an unconscious state. CT and MRI on the second day after hospitalization revealed cerebellar infarction. He was diagnosed as brain dead on day 4. Case 2 was a 35-year-old man. When he was transferred to our hospital, he was in cardiorespiratory arrested. Cardiac resuscitation was successful but no spontaneous respiration appeared. CT and MRI on admission revealed right intracerebral hemorrhage. Angiography revealed cessation of contrast medium in intracranial vessels in both of the patients. We found no &apos;flow signal void sign&apos; in the bilateral internal carotid and basilar arteries on MRI images in both cases after brain death. MRI, showing us the anatomical changes of the brain, clearly revealed brain herniations, even though only nuclear findings of &apos;brain tamponade&apos; were seen on CT. But in Case 1, we could not see the infarct lesions in the cerebellum on MR images obtained after brain death. This phenomenon was caused by the whole brain ischemia masking the initial ischemic lesions. We concluded that MRI was useful not only the anatomical display of lesions and brain herniation with high contrast resolution but for obtaining information on cerebral circulation of brain death.

    The author presents the forgotten fact that in 1905 there were 2 restricted theories of relativity: that of Einstein and that of Poincare. These 2 theories were independently formulated, they are very close to each other but are fundamentally different when we consider their basic principles. Poincare&apos;s theory is based on a classical representation of the purely undulatory aspect of light, whereas Einstein stipulates for the quantum aspect of light. Poincare&apos;s theory implies the existence of the ether and asserts the primacy of continuity over discontinuity. The author has based his work on a thorough study of the scientific articles in which Poincare and Einstein explained their ideas. The comparison of these 2 theories sheds light on the evolution of concepts on which the whole modern physics is based. An extended bibliography of works published on special relativity or on related topics is given. (A.C.)

Our new L&apos;-band observations taken with the Large Binocular Telescope and L/M-band InfraRed Camera recover the companion (ΔL = 10.15 ± 0.15 mag, ρ = 0.&apos;&apos;675 ± 0.&apos;&apos;016) with a high signal-to-noise ratio (10σ). This measurement represents the deepest L&apos; high-contrast imaging detection at subarcsecond separations to date, including extrasolar planets. We confirm that HD 114174 B has near-infrared colors consistent with the interpretation of a cool white dwarf (WD; J – L&apos; = 0.76 ± 0.19 mag, K – L&apos; = 0.64 ± 0.20). New model fits to the object&apos;s spectral energy distribution indicate a temperature T {sub eff} = 4260 ± 360 K, surface gravity log g = 7.94 ± 0.03, a cooling age t{sub c} ≈ 7.8 Gyr, and mass M = 0.54 ± 0.01 M {sub ☉}. We find that the cooling ages given by theoretical atmospheric models do not agree with the age of HD 114174 A derived from both isochronological and gyrochronological analyses. We speculate on possible scenarios to explain the apparent age discrepancy between the primary and secondary. HD 114174 B is a nearby benchmark WD that will ultimately enable a dynamical mass estimate through continued Doppler and astrometric monitoring. Efforts to characterize its physical properties in detail will test theoretical atmospheric models and improve our understanding of WD evolution, cooling, and progenitor masses.

    The treatment of Hodgkin&apos;s lymphoma has changed considerably in the last decades. This entity is now one of the most curable human malignancies. With improved survival and extended follow-up, relevance of treatment induced late effects became more evident. Therefore modern therapeutic strategies must maximize chance of cure and minimize the risk of therapy associated toxicity. Here we review the pathology of Hodgkin’s lymphoma, clinical presentation, risk stratification, current treatment approaches and toxicity of the treatment. (author)

    The paper presents the experimental validation of the &apos;&apos;EasyTest Cell&apos;&apos; operational principle via comparative electrochemical tests on MEAs carried out in three types of electrochemical hydrogen energy conversion (EHEC) testing cells: conventional polymer electrolyte membrane fuel cells (PEMFC) and polymer electrolyte membrane water electrolyzers (PEMWE), properly equipped with all the required auxiliaries (products conditioning and supplying, reagents removal, etc.), and the simple, autonomous EasyTest Cell. Along with EasyTest Cell validation and demonstration of its advantages, the influence of argon pressure during sputtering on the electrode characteristics, including gas diffusion limitations was investigated. The electrodes under investigation were magnetron sputtered C/Ti/IrO{sub x} (IrO{sub x} loading in the range 0.12-0.4 mg cm{sup -2}), C/Ti/IrO{sub x}/Pt/IrO{sub x} (IrO{sub x} 0.08/Pt 0.06/IrO{sub x} 0.08 mg cm{sup -2}), sputtered at various argon pressure C/Ti/Pt (0.15 and 0.25 mg cm{sup -2}), and commercial ELAT electrode (V.21, Lot MB030105-1, Pt loading 0.5 mg cm{sup -2}, E-TEK). The results obtained proved the reliability, simplicity (running-periphery-free) and broadened experimental possibilities of EasyTest Cell over PEMFC and PEMWE single cell testing. Thus, significant cost reduction and resource saving in R and D laboratory can be achieved. Moreover, validation of EasyTest Cell contributes not only to testing facilitations, but potentially to standardization of MEA testing since it gives possibilities for precise control and more uniform distribution of the working parameters applied to the testing object, which are both compulsory for performance comparison and qualifying.

    Volatile organic compounds (VOCs) are suspected to contribute significantly to &apos;&apos;Sick Building Syndrome&apos;&apos; (SBS), a complex of subchronic symptoms that occurs during and in general decreases away from occupancy of the building in question. A new approach takes into account individual VOC potencies, as well as the highly correlated nature of the complex VOC mixtures found indoors. The new VOC metrics are statistically significant predictors of symptom outcomes from the California Healthy Buildings Study data. Multivariate logistic regression analyses were used to test the hypothesis that a summary measure of the VOC mixture, other risk factors, and covariates for each worker will lead to better prediction of symptom outcome. VOC metrics based on animal irritancy measures and principal component analysis had the most influence in the prediction of eye, dermal, and nasal symptoms. After adjustment, a water-based paints and solvents source was found to be associated with dermal and eye irritation. The more typical VOC exposure metrics used in prior analyses were not useful in symptom prediction in the adjusted model (total VOC (TVOC), or sum of individually identified VOCs (ΣVOCi)). Also not useful were three other VOC metrics that took into account potency, but did not adjust for the highly correlated nature of the data set, or the presence of VOCs that were not measured. High TVOC values (2--7 mg m-3) due to the presence of liquid-process photocopiers observed in several study spaces significantly influenced symptoms. Analyses without the high TVOC values reduced, but did not eliminate the ability of the VOC exposure metric based on irritancy and principal component analysis to explain symptom outcome.

    The purpose of this study was to describe the imaging characteristics of subcutaneous amyloid deposits occurring at sites of insulin injection, commonly known as &apos;&apos;insulin balls,&apos;&apos; in diabetic patients on ultrasound, CT, and MRI with pathologic correlation. We retrospectively reviewed the radiographic findings of 14 lesions in 9 patients diagnosed with subcutaneous amyloid deposits at our institution between 2005-2015. Three board-certified radiologists analyzed the following: (1) the shape, size, margin, morphologic characteristics, and blood flow on US using the color Doppler signal, (2) shape, size, margin, attenuation, and presence or absence of contrast enhancement on CT, and (3) shape, size, margin, signal intensity, and presence or absence of contrast enhancement on MRI. All lesions showed ill-defined hypovascular subcutaneous nodules with irregular margins. The median diameter of lesions was 50.4 mm on US, 46.8 mm on CT, and 51.4 mm on MRI. The internal echogenicity of subcutaneous amyloid deposits was hypoechoic and heterogeneous on US. All lesions showed isodensity compared to muscle with irregular margins and minimal contrast enhancement on CT. Both T1- and T2-weighted MR images showed low signal intensity compared with subcutaneous fat. Normal diffusion and minimal contrast enhancement were seen. Subcutaneous amyloid deposits which cause insulin resistance are typically ill-defined and heterogeneous hypovascular subcutaneous nodules with irregular margins on imaging that correspond to insulin injection sites. It is also characteristic that T2WI shows low intensity compared with fat on MRI, reflective of the amyloid content. (orig.)

  16. Analysis of &apos;&apos;new physics&apos;&apos; in the flavor sector using effective field theory methods

    2010-02-05

    The enormous amount of data collected by the B factories as well as the perspective concerning the upcoming experiments at the LHC provide us with the opportunity to perform high precision tests of the standard model. This dissertation presents two model independent precision tests of the weak sector of the standard model using extensions of the weak currents which are set up using effective field theory methods in order to control the size of the different contributions. Constraints on the coefficients of the terms can then be obtained by comparison with experimental results. The first analysis incorporates a test of the lefthandedness of the weak interaction in the quark sector. By introducing additional weak couplings the differential and total decay rates of the inclusive semileptonic decay anti B {yields} X{sub c}l anti {nu}{sub l} are calculated. The calculation includes the computation of the heavy-quark expansion which describes the interaction of the decaying b quark with respect to the background field of the B meson, up to order 1/m{sub b}{sup 4}. This has been done in a new, systematic way which does not involve the calculation of gluon matrix elements. Furthermore, radiative corrections have been included up to order O({alpha}{sub s}) including renormalization group running. The second part deals with the introduction of lepton flavor violating operators in the context of leptonic {tau} decays. These operators give rise to the effective four-fermion vertex {tau}{yields}ll{sup &apos;}l'&apos; as well as the subsequent radiative decay {tau}{yields}l{gamma}{sup *}{yields}ll{sup &apos;+}l{sup &apos;-}. The resulting Dalitz distributions turn out to predict completely different signatures for the radiative and the effective four-fermion vertices and provide the opportunity to check, whether the decay is induced either by a radiative or by an effective four-fermion vertex. Since different models which contain lepton flavor violation are normally more

    &apos;Climate change&apos; is an oft avowed environmental priority among cooperation and development actors. The Palestinian Territories, for their part, are one of the largest recipients of international aid. To the degree that the UNPD has played a role in promoting the question of &apos;climate change&apos;, the dependence of the Palestinian Authority on international aid has contributed to framing this emergent public problem; its construction is anchored in the context of the Israeli-Palestinian conflict and the Palestinian state&apos;s demand for recognition at the international level. In the international arenas dedicated to &apos;climate change&apos;, what&apos;s more, the Palestinian Authority discusses this question in terms of political and climatic injustice. Two questions thus merit study: what effect does the construction of the climate problem have on the Palestinian Authority and, conversely, what effect does the Palestinian Authority have on the construction of the climate problem?

    A response is given to a criticism in a paper by Kim and Overhauser of an earlier work by Abrikosov and Gor&apos;kov on superconductors with impurities. The criticism is based on a primitive misunderstanding of the nature of the attraction of electrons achieved by phonons. As it was explained by the present authors in several publications, there exists a complete equivalence of their results with the later work by Anderson.

    &apos;&apos;Cold fusion is dead, isn&apos;t it?&apos;&apos; is a question I am often asked. The reply is a strange one, &apos;&apos;Yes, scientifically it is dead, but not from a media point of view or from funding&apos;&apos; In 1989 two electrochemists, Martin Fleischmann and Stanley Pons, claimed sustained nuclear fusion had been achieved in a test-tube with a palladium cathode and deuterium, observing excess heat, neutrons and tritium. A series of encouraging confirmations and successively greater excess heat claims were seized on by the world&apos;s media. The US Government set up a panel of some 20 world-class scientists from several disciplines under John Huizenga, distinguished professor of Chemistry and Physics at the University of Rochester. They concluded that there was no present evidence for the discovery of a new nuclear process termed cold fusion. It might be thought that would end cold fusion, but for interesting reasons, it did not entirely. John Huizenga has written a book describing the curious claims and evidence for cold fusion and has given an excellent explanation of the science involved. This was published as a hardback book of 236 pages, telling the story up to the end of June 1990. Again one might think it was the end of the cold fusion story. Now he has written about what happened in the next two years in a paperback book which contains an epilogue of 51 pages. If you thought the first year was extraordinary, the next two years described in the new edition were even more incredible! In the main part of the book, the basic science is simply and clearly explained. The number of &apos;'miracles'&apos; required for each results or theory is described - a &apos;'miracle'&apos; is a gross violation of previous knowledge and experimental results such as energy conservation. Thus some theories are classified as &apos;&apos;triple miracles&apos;&apos;. It might be thought that people who claimed to have observed cold fusion

    The topic of &apos;&apos;green economy&apos;&apos; took centre stage at last year&apos;s UN conference on sustainable development in Rio de Janeiro. The term &apos;&apos;green economy&apos;&apos; has many interpretations to it, ranging from an emphasis on energy and resource efficiency in an otherwise ordinary economy to positions that are critical of growth as such. What can be considered as the essence of the concept of green economy, and what challenges need to be mastered on the way there? The present study shows that there is more to the term than most companies and consumers are aware of.

    The concept &apos;environment&apos; is of considerable importance in present-day engineering thermodynamics. Introduction of this concept in operation brings not only simplification of the methods of solving classical thermodynamic problems, but also gives the exergy method which forms the major new part of thermodynamics, including some parts of biology, economics and other fields of science. But practice shows that it is necessary to define the concept &apos;environment&apos; more precisely in some cases.

    Due to the global climate change, the power industry has a lot of changes in store. For reasons of environmental protection, the reduction in CO{sub 2} emissions in power generation and loss minimization in power transmission are of particular importance. This means that the share of wind power in a lot of countries, Germany among them, must be as high as possible, for the other &apos;'green'&apos; energy resources, such as hydro or solar power, play only a subordinate part for reasons of their geographical location. Along with sustainability and efficiency of power supply, grid security must be taken into account as well. (orig.)

    The &apos;&apos;Cobalt 60 Case&apos;&apos; in Taiwan gives an opportunity for check of the thesis of radiation hormesis. Apartment residents have been exposed to cobalt-60 contaminated steel buildings. The results of a study strongly suggest that whole-body chronic irradiation, in the dose rate range that the apartment residents received, caused no symptomatic adverse health effects, such as radiation sickness, or the increased cancer or increased congenital disease that are predicted by ICRP theories. On the contrary, those who were exposed had lower incidences of cancer mortality and congenital malformations.

    On-the-job training (OJT) has been with us in varying forms for longer than perhaps any other type of training. In reality, OJT is a process for accomplishing change; change in an employee&apos;s ability to perform assigned job duties. However, bringing about that change can often be a difficult process. A clear understanding of what change really is and what it entails is essential to easing its process. this document discusses the methodology in OJT and emphasizes the importance of communications in this process.

  1. May Goedel&apos;s Ideas Be Addressed Philosophically?

    Dokulil, Milos [Department of Information Technologies, Faculty of Informatics, Masaryk University, Botanicka 68a, 602 00 Brno (Czech Republic)

    2007-11-15

    Goedel emphasised philosophy as an important tool in science. Much less is known about his religious background. We should bear in mind that our evaluational perspective differs very much from the one in which Goedel lived. He was personally sure that there must be another existence after death-an afterlife (&apos;of unlimited life span&apos;). As a &apos;Baptized Lutheran&apos; he did not include &apos;Trinity&apos; in his creed. He was also certain that mind is separate from matter. This text tries to include Libet&apos;s &apos;readiness potential&apos; into the debate concerning the specificity of the mind. Neither Goedel&apos;s identification of materialism with mechanism nor his vision of the &apos;spirit&apos; are a viable solution of the problem.

    This thesis work is about the validation of the new criticality-safety package CRISTAL and contributes to the modernization and the improvement of the computational tools. The first part presents neutronic elements, the objectives of safety criticality studies and the package CRISTAL. Then, the validation work concerned two series of experiments involving uranyl solutions (UO{sub 2}F{sub 2}) and UO{sub 2} powders. For these experiments, the differences between the computation results and the experimental results were analysed. It was highlighted interesting physical phenomena such of the compensations of errors between the approximate representation by the 99 energy group structure on the first resonance of oxygen and the anisotropy of the diffusion simulation as well as the influence of uranium 234 in high enriched solutions in uranium 235. Once the work of the experimental qualification carried out, raises the question of the use the base of qualification and the &apos;'calculation-experiment'&apos; variations which are referred to it. It is often difficult to establish the link between the &apos;&apos;studied configuration&apos;&apos; and the experiments of the base of qualification. The presented characterisation system proposes to answer in a way automatic and quantified this difficulty: - in bringing an answer on the package qualification for the studied configuration, - in giving an estimate of the package bias. To answer these points, it was defined a set of 35 characteristic neutronic parameters representing the behaviour of the medium. To process the information brought by these parameters and to use it to answer the objectives of the system, we called upon statistical methods (Principal Components Analysis and Sliced Inverse Regression). The results obtained in the feasibility studies showed the relevance of these methods for the considered objectives. (author)

  4. Absence of toroidal moments in &apos;aromagnetic&apos; anthracene

    Colloidal suspensions of anthracene and other aromatic compounds have been shown to respond to a magnetic field as if they possessed a permanent magnetic moment. This phenomenon was named &apos;aromagnetism&apos; by Spartakov and Tolstoi, and it was subsequently attributed to the interaction of an electric toroidal moment with a time-varying magnetic field. However, there has been no independent confirmation of the original work. Here, we have selected purified anthracene crystallites which respond to a low magnetic field and investigate how this response depends on the gradient and the time derivative of the field. We conclude that the anomaly cannot be attributed to a toroidal interaction but is due to a constant magnetic moment of the particles. Close examinations using magnetometry and scanning electron microscopy reveal metallic clusters of Fe and Ni up to a few hundred nanometres in size embedded in the anomalous crystallites. These inclusions represent 1.8 ppm by weight of the sample. The observed presence of ferromagnetic inclusions in the ppm range is sufficient to explain the anomalous magnetic properties of micron-sized anthracene crystals, including the reported optical properties of the colloidal suspensions.

  5. File &apos;Energy-climate actions in Sweden&apos;

    International Nuclear Information System (INIS)

    2009-01-01

    In a first part, this publication briefly presents some basic data and information on Sweden (geography, population, economy, administrative organisation, powers of local authorities, local finances), the Swedish &apos;energy profile&apos; (consumption, intensity, imports and exports), greenhouse gas emissions (total and per sector), and the energy-climate strategy (impacts of climate change, national climatic strategy, national measures, action framework for local authorities). The second part addresses one of these action frameworks, the Klimatkommunernas network. It describes this network, its objectives, and possibilities for communities to join it. It describes its activities: information, publication of a strategic document of climate-energy actions for municipalities, examples of projects. The third part presents experiments performed by different local communities (Kristianstad, Vaexjoe, Malmoe, and Lund). For each of them are presented: the energy strategy (objectives, strategy, adaptation, energy-climate follow-up, application and actual measures), and some specific measures. These specific examples can be integrated systems based on biogas and biomass, a zero fossil fuel objective with the use of renewable energies for heat and cold production, for electricity production and to improve energy efficiency, to promote green fuels in transports, to reduce the impact of transports on climate, a sustainable town planning, environmental management. Some features are then highlighted in the adopted approach for these examples: a systemic, collaborative, participative and communicative approach

    The energy system&apos;s transformation away from fossil and therefore finite resources and ecological harmful use towards renewable energy sources and sustainable forms of usage proceeds. But even after 35 years, the German energy transition has yet not reached its ambitious goals. Moreover, in the recent years the progress has stagnated in certain areas. This is due to the fact that one of the central challenges of the energy system&apos;s changeover to an sole use renewable energy (RE) have not yet mastered: the reliable and stable delivery of RE for all energy dependent sectors starting form electricity via heat to mobility in the face of fluctuating energy sources like sun and wind. Bioenergy with its flexible use of innovative technologies and smart integration in the overall system is therefore vital to grant stability of energy supply. Furthermore, bioenergy can recourse on sustainable resources and may become therefore the backbone of the future bioeconomy. For this purpose an integrative approach is necessary that aligns the aforementioned building blocks in a cohesive whole: the Smart Bioenergy concept - that will be presented here with its elements but also open questions and challenges.

    This report summarises SKI&apos;s and SSI&apos;s joint review of the Swedish Nuclear Fuel and Waste Management Co&apos;s (SKB) safety report SR-Can (SKB TR-06-09). SR-Can is the first assessment of post-closure safety for a KBS-3 spent nuclear fuel repository at the candidate sites Forsmark and Laxemar, respectively. The analysis builds on data from the initial stage of SKB&apos;s surface-based site investigations and on data from full-scale manufacturing and testing of buffer and copper canisters. SR-Can can be regarded as a preliminary version of the safety report that will be required in connection with SKB&apos;s planned licence application for a final repository in late 2009. The main purpose of the authorities&apos; review is to provide feedback to SKB on their safety reporting as part of the pre-licensing consultation process. However, SR-Can is not part of the formal licensing process. In support of the authorities&apos; review three international peer review teams were set up to make independent reviews of SR-Can from three perspectives, namely integration of site data, representation of the engineered barriers and safety assessment methodology, respectively. Further, several external experts and consultants have been engaged to review detailed technical and scientific issues in SR-Can. The municipalities of Oesthammar and Oskarshamn where SKB is conducting site investigations, as well NGOs involved in SKB&apos;s programme, have been invited to provide their views on SR-Can as input to the authorities&apos; review. Finally, the authorities themselves, and with the help of consultants, have used independent models to reproduce part of SKB&apos;s calculations and to make complementary calculations. All supporting review documents are published in SKI&apos;s and SSI&apos;s report series. The main findings of the review are: -SKB&apos;s safety assessment methodology is overall in accordance with applicable regulations, but part of the methodology needs to be

    The europium(III) complex 1-Cl{sub 3} (S,S-2,2{sup &apos;}-(((1,10-phenanthroline-2,9-diyl)bis(methanylylidene))bis (azanylyliden e))bis(3-methylbutanamide)europiumtrichloride) undergoes, only in the presence of the amino acid tryptophan, a change of emission at 615 nm. In the presence of few equivalents of tryptophan, emission of the europium complex is enhanced while it disappears upon addition of large amounts. This behavior can be assigned to displacement of the sensitizing phenanthroline ligand of 1-Cl{sub 2} x Trp in the latter case.

    The &apos;&apos;penumbra sign&apos;&apos; on unenhanced T1-weighted MR sequences is thought to be helpful for discriminating subacute osteomyelitis from bone neoplasm. We sought to quantify the sensitivity and specificity of this sign for bone and soft tissue infection in a general referral population. Clinical coding was used to identify patients admitted to Middlemore Hospital (Auckland, New Zealand) between January 2000 and November 2003 with a diagnosis of either infection or neoplasm of the upper or lower limb who had undergone an MRI scan. One hundred and eighty-three patients were included in the study. Fifty-seven patients had bone or soft tissue infection. One hundred and twenty-six had a bone or soft tissue neoplasm. Relevant unenhanced T1-weighted images were selected for each patient, randomised and placed in a folder on the Hospital PACS system. Four reviewers were shown the original article describing the penumbra sign and then asked to look at the images in the folder stating whether the penumbra sign was present or absent. The average specificity and sensitivity of the penumbra sign for musculoskeletal infection was 96% (range 94-99%) and 27% (range 21-34%) respectively. Interobserver reliability was moderate to good with an average kappa score of 0.57 (range 0.50-0.62). For isolated soft tissue infection there was a higher sensitivity (54%, 33-83%) but with similar specificity (98%, 96-100%) and interobserver reliability (0.47, 0.33-0.58). Of the 11 out of 57 (19%) true positive penumbra signs identified by a consensus of three or more of the observers, all were subacute, chronic or acute on chronic infections. The penumbra sign has a high specificity for musculoskeletal infection. This is also true for isolated soft tissue infection. The penumbra sign is helpful in differentiating neoplasm from infection and its presence in the setting of a high pretest probability is useful in making a diagnosis of infection. (orig.)

    In recent years, a growing interest in the equilibrium of compact astrophysical objects like white dwarf and neutron stars has been manifested. In particular, various modifications due to Planck-scale energy effects have been considered. In this paper we analyze the modification induced by gravity&apos;s rainbow on the equilibrium configurations described by the Tolman-Oppenheimer-Volkoff (TOV) equation. Our purpose is to explore the possibility that the rainbow Planck-scale deformation of space-time could support the existence of different compact stars. (orig.)

    Energy Technology Data Exchange (ETDEWEB)

    MacGregor, James; Vorley, Bill

    2006-10-15

    The concept of &apos;food miles&apos; presents an argument to buy goods which have travelled the shortest distance from farm to table, and to discriminate against long-haul transportation, especially air-freighted goods. The long-distance transport of food is associated with additional emissions due to increased transportation coupled with greater packaging, as well as a disconnection between the public and local farming. Furthermore, &apos;food miles&apos; encapsulates (and is at the vanguard of) the climate change debate in the UK. In light of growing international concern over the speed and scale of climate change, the concept of &apos;food miles&apos; has captured public attention and apparently is changing some consumers&apos; behaviour, although only around one-third of shoppers know of the concept.

    This paper introduced the Mr. Sakaiya&apos;s lecture on the &apos;Negligence = Oil Shortage&apos; and international energy conditions in the future held at the 20th anniversary of the Agency of Natural Resources and Energy. The present Japan&apos;s conditions are very similar to those at the Oil Crisis. Japan is now in &apos;Negligence&apos;. The prosperity brought about by the decline of oil price staggers Japan&apos;s intention of developing the nuclear power generation. There is no feeling of energy crisis all over the world. The demand/supply of oil resources, international relation, social and economical trend, and technical innovation after the Oil Crisis were explained. The pig cycle of economy can be clearly seen in energy, food, and gold price. The human being is apt to indulge into negligence in the experience in memory and the historical repetition. For the oil forecast, they say that it will be fine or cloudy and the rainfall probability is 15 %. The resources and energy requires a long term vision. The nuclear power generation is important. The social tolerance to the development of nuclear power generation is necessary to get rid of the oil dependency. Let&apos;s not repeat the trouble in railway construction. All the people have to be interested in nuclear power.

  18. Japan&apos;s new energy policy

    International Nuclear Information System (INIS)

    2014-11-01

    Japan&apos;s energy policy is undergoing fundamental changes. The accident at TEPCO&apos;s Fukushima Daiichi nuclear power plant questions the future contribution of nuclear power in the national energy mix. Growing imports of fossil fuels to replace the lost nuclear capacity inflated energy prices and raise economic and energy security challenges. At the same time, the US shale gas and oil revolution is reshaping the global energy scene. Japan expects to take advantage of the trend to eliminate the &apos;Asian premium&apos; on natural gas prices and expand cheaper natural gas consumption. These developments have driven the Government of Japan to review its energy policy from scratch and adopt a new Strategic Energy Plan. This new policy has far reaching implications for gas and coal development in Japan but also for the international markets as Japan is the world&apos;s largest LNG importer and the second largest coal importer. This document summarizes the key findings of a new report by CEDIGAZ &apos;Japan&apos;s new energy policy: In search for stable and competitive energy supply&apos;. The report analyzes the current changes taking place on the gas and coal markets in Japan, in light of the new energy policy adopted in April 2014, and in particular the decision to restart safe nuclear power plants and push forward electricity market reforms

    Using combined STEREO-A and STEREO-B EUVI, COR1, and COR2 data, we derive deprojected coronal mass ejection (CME) kinematics and CME &apos;'true'&apos; mass evolutions for a sample of 25 events that occurred during 2007 December to 2011 April. We develop a fitting function to describe the CME mass evolution with height. The function considers both the effect of the coronagraph occulter, at the beginning of the CME evolution, and an actual mass increase. The latter becomes important at about 10-15 R{sub Sun} and is assumed to mostly contribute up to 20 R{sub Sun }. The mass increase ranges from 2% to 6% per R{sub Sun} and is positively correlated to the total CME mass. Due to the combination of COR1 and COR2 mass measurements, we are able to estimate the &apos;'true'&apos; mass value for very low coronal heights (<3 R{sub Sun }). Based on the deprojected CME kinematics and initial ejected masses, we derive the kinetic energies and propelling forces acting on the CME in the low corona (<3 R{sub Sun }). The derived CME kinetic energies range between 1.0-66 Multiplication-Sign 10{sup 23} J, and the forces range between 2.2-510 Multiplication-Sign 10{sup 14} N.

    Phase 2 of the project &apos;mini-cogeneration in the flower bulb industry&apos; is the sequel to the report &apos;mini-cogeneration in the flower bulb industry. Use of cogeneration in the cultivation and hot bed of tulip and hyacinth&apos;, Addressing the incentivisation of the use of cogeneration in the sector and working toward realizing a number of demonstration projects. To this end it is necessary that potential investors are given insight in the feasibility of cogeneration at their business and that their enthusiasm is kindled for the use of cogeneration. This was done by disseminating information in the flower bulb industry about the opportunities of cogeneration and by informing growers about technique, economy and points of interest. [Dutch] Fase 2 van het project &apos;Mini- WKK in de bloembollensector&apos; is een vervolg op het rapport &apos;Mini-wkk in de bloembollensector. Toepassing van wkk bij teelt en broei van tulp en hyacint&apos; en richt zich op het stimuleren van de toepassing van WKK in de sector en toewerken naar realisatie van een aantal demonstratieprojecten. Daartoe is het noodzakelijk dat potentiele investeerders inzicht krijgen over de haalbaarheid van WKK op hun bedrijf en geenthousiasmeerd worden voor het gebruik van WKK. Dit is gedaan door informatie in de bollensector te verspreiden over de mogelijkheden van WKK en telers te informeren over techniek, economie en aandachtspunten.

    In 2001, a diverse group of citizens ranging from conservationists to industrial developers joined forces to produce a factual description of Oak Ridge&apos;s environment and the issues associated with contamination on the U.S. Department of Energy (DOE) reservation. This consensus effort was a result of common values not generally seen in this spectrum of philosophies, and of shared concerns about rising property taxes, declining city services, fleeing retail establishments, and diminishing real estate values. These problems are attributed to waning local DOE budgets coupled with Oak Ridge&apos;s national reputation of being contaminated and unsafe. This undeserved reputation harms the city&apos;s ability to attract new industry to replace declining federal employment and to induce families to live in the community. Representatives from a spectrum of conservation, environmental, economic development, local government, and civic organizations were invited to meet regarding how to best explain the complex environmental story of Oak Ridge and the DOE reservation. This large group decided to publish a straightforward explanation of the environmental quality of the city and its relationship to the DOE reservation in easy-to-understand language. The result was Oak Ridge, Tennessee--A Citizen&apos;s Guide to the Environment, a 28-page glossy booklet, distributed through the Chamber of Commerce and other organizations. The Oak Ridger ensured wide distribution in the community by publishing it as an insert in the daily paper. The material is also available on several web sites. A trifold brochure summarizing and promoting the larger document was also produced for wider distribution. The integrity of the Citizen&apos;s Guide was ensured by having a six-member editorial team manage writing and review of the document. There was no direct involvement by the DOE and its contractor. Knowledgeable citizen writers from throughout the community contributed technical and descriptive

    The aim of this thesis is the description of the process of institutionalization of nuclear research in Austria in the context of the „Atoms for Peace“ program in the 1950s. This aspect of the history of Austrian nuclear research has been relatively unexplored. The focus of this work is the presentation of measures that have been put in Austria to participate in the &apos;Atoms for Peace&apos; program. Moreover, the expectations and goals of the Austrian nuclear program are analyzed. For this purpose, foundation, structure and research activities of the “Austrian Atomic Energy Commission”, the “Austrian Society for the Study of Atomic Energy” and the “Nuclear Reactor Centre Seibersdorf“ in the period from 1954 until about 1970 are examined. To establish a relationship with the international historical research of the history of nuclear research, the Austrian situation is compared to the Swiss and the German. It turns out that the Austrian expectations and objectives in nuclear research at the beginning of the period of observation roughly corresponded with the international trends. It also follows that by the establishment of the SGAE and the “Nuclear Reactor Centre Seibersdorf“ the development course of Austrian nuclear research occupied a special position compared to foreign institutions.(author) [de

    The energy system&apos;s transformation away from fossil and therefore finite resources and ecological harmful use towards renewable energy sources and sustainable forms of usage proceeds. But even after 35 years, the German energy transition has yet not reached its ambitious goals. Moreover, in the recent years the progress has stagnated in certain areas. This is due to the fact that one of the central challenges of the energy system&apos;s changeover to an sole use renewable energy (RE) have not yet mastered: the reliable and stable delivery of RE for all energy dependent sectors starting form electricity via heat to mobility in the face of fluctuating energy sources like sun and wind. Bioenergy with its flexible use of innovative technologies and smart integration in the overall system is therefore vital to grant stability of energy supply. Furthermore, bioenergy can recourse on sustainable resources and may become therefore the backbone of the future bioeconomy. For this purpose an integrative approach is necessary that aligns the aforementioned building blocks in a cohesive whole: the Smart Bioenergy concept - that will be presented here with its elements but also open questions and challenges.

    Politics of course has more than its fair share of those who know everything and do their best not to let get the facts get in the way where inconvenient truths risk destroying their &apos;'Besserwisser'&apos; illusions. An example of this is a letter from Germany&apos;s federal environment minister Barbara Hendricks to her French counterpart Segolene Royal. The subject of the letter was the closure of France&apos;s Fessenheim nuclear power plant. The content of the letter appears to show that, not content with stamping out the use of nuclear energy in Germany and all the knowledge and industrial expertise that goes with it, Germany seems intent on imposing its point of view onto its neighbour. Hendricks acknowledges that any decisions relating to Fessenheim are for France alone as a sovereign nation. But, if that is the case, why bother to write the letter in the first place? In reply Royal, a prominent French Socialist, stresses French president Francois Hollande&apos;s desire to close Fessenheim before his term of office draws to a close. Royal also noted that it is up to France&apos;s nuclear operator, EDF, to &apos;&apos;define which reactors are removed from the grid&apos;&apos;. It is also amusing to read Royal&apos;s comment that the fact Fessenheim can be closed at all is largely due to the construction of replacement nuclear capacity at Flamanville, in northern France. Surely that irony could not have been lost on Germany&apos;s environment ministry.

    The aim of this study was to examine the effect of the ApoE genotype on the association between head circumference (HC) and cognition. Cross-sectional factorial design in which Korean version of Mini Mental State Examination (K-MMSE) score was the dependent variable with ApoE4 status as one factor and HC as the other. A longitudinal cohort study of the Korea Health 21 R&D Project Clinical Research Center for Dementia. A total of 1,902 Koreans (599 men and 1303 women) aged over 60 years. Cognitive function was assessed by the K-MMSE. HC and ApoE genotyping were carried out on all subjects. The HC was correlated with the K-MMSE scores (r = 0.22, df = 1,525, p MMSE was observed after adjusting for the age, sex, educational level, height, and weight (F = 2.527, df = 4, 1, 364, p = 0.039). A test of simple main effect according to ApoE status showed that, in the ApoE epsilon 4(-) group, the mean of K-MMSE between HC quintile was not different (F = 0.517, df = 4, 1,148, p = 0.723). But in the ApoE epsilon 4(+) group, the mean of K-MMSE between HC quintile was significantly different. (F = 4.163, df = 4, 211, p = 0.003). All these findings suggest the possibility that the presence of ApoE epsilon 4 affects cognitive function only when the brain reserve is low. In other words, these findings support the structural "brain reserve hypothesis," and the effects are more pronounced in genetically predisposed individuals.

    Environmental policy is an art of execution. Hence the fact that European Union member states have recently managed to agree on targets of emissions to fight climate change leaves open the question of how they will meet them. Economics cannot but embrace the scientific consensus on climate change and cannot say much about the efficiency of alternative technologies. Yet, its expertise is valuable to calculate economic effects and fairness of policies and to assess the relevance of incentives structures and effectiveness of institutions put into place to convert scientific consensus into action. This article is concerned with this latter point: does the EU have the right institutions to fight climate change? We claim that such is not the case, and offer to institute a &apos;European Community of Environment, Energy and Research&apos; to go forward.

    The present project, whose abbreviated name is RENOX, has the aim of reducing NO{sub x} emissions from the combustion of hard coals or coals with low volatile matter contents. It is applied to the combustion of these coals in arc boilers (or &apos;'U'&apos; boilers), where the necessary combination of long presence times and high hearth temperatures facilitates the high NO{sub x} levels reached. The intended reduction in emissions is approached through the application of primary combustion measures, also known as adjustment or refining of combustion. This solution is adopted for two reasons: due to its efficiency in environmental and economic terms, and because it is an unavoidable step if the levels to be attained require the installation of specific gas crubbing systems (secondary measures). The practical nature of RENOX has led to the development of the project in two phases, corresponding to two logical stages: phase 1, associated with the RNA project, on the characterization of emissions and combustion, complex numeric modelling of flows inside the boiler, and determination of the viability and scope of the optimization of emissions, and phase 2, the OPTINOXproject, which follows the methodology and lessons of the first phase and, as a natural continuation of this, deals with the design, development, manufacturing and validation of a computerized system that processes real time data on the boiler where it is installed to monitor, supervise and control the commercial operation of the plant, optimizing its combustion efficiency and/or NO{sub x} emissions. The practical objective of this project is represented by the construction of a validated prototype to demonstrate the OPTINOX system, which is capable of determining operating and control strategies that can minimize NO{sub x} emissions without unfavourably affecting the productivity and specific consumption of the units. Phase 1 development activities took place in groups 3, 4 and 5 of Compostilla

    After decades of slow evolutions, and because of the emergence of renewable energies and of a multiplication of actors due to the liberalisation of energy markets, electric networks are entering a phase of large and complex development which will lead to a massive introduction of intelligence and to the building up of the &apos;smart grid&apos; concept. The authors first identify the characteristics of the new energetic paradigm. The present operation of electric grids is based on four components: production by means of high power units installed in strategic locations, transport to consumption centres by means of a highly instrumented transport network which has highly centralised and hierarchical management, and consumers who are passive actors. They comment the implications of recent development for these three components. They describe how information and communication technologies (ICT) are used at the service of the grid, and how new technologies are integrated in different instruments (smart counter, actuators, fast cut devices, sensors, advanced supervision and control functions). Then they discuss the definition of a smart network or smart grid, the objectives it allows to be reached for energy transport as well as energy distribution. They discuss the desirable evolution of distribution networks and their technical objectives. Then, they give an overview of the various involved actors (consumers, network managers, electric equipment manufacturers, energy producers, and so on), evokes bodies and institutions involved in research on smart grids (notably in Grenoble within the INPG), give some examples of innovative concepts which are now being developed (intelligence distribution, virtual central station, grid monitoring, re-configurable grid, smart building). They also identify scientific and technological deadlocks, and outline the challenge of preparing the needed abilities for the development of smart grids

    Apolipoprotein E (apoE) is a major carrier of cholesterol and essential for synaptic plasticity. In brain, it's expressed by many cells but highly expressed by the choroid plexus and the predominant apolipoprotein in cerebrospinal fluid (CSF). The role of apoE in the CSF is unclear. Recently, the glymphatic system was described as a clearance system whereby CSF and ISF (interstitial fluid) is exchanged via the peri-arterial space and convective flow of ISF clearance is mediated by aquaporin 4 (AQP4), a water channel. We reasoned that this system also serves to distribute essential molecules in CSF into brain. The aim was to establish whether apoE in CSF, secreted by the choroid plexus, is distributed into brain, and whether this distribution pattern was altered by sleep deprivation. We used fluorescently labeled lipidated apoE isoforms, lenti-apoE3 delivered to the choroid plexus, immunohistochemistry to map apoE brain distribution, immunolabeled cells and proteins in brain, Western blot analysis and ELISA to determine apoE levels and radiolabeled molecules to quantify CSF inflow into brain and brain clearance in mice. Data were statistically analyzed using ANOVA or Student's t- test. We show that the glymphatic fluid transporting system contributes to the delivery of choroid plexus/CSF-derived human apoE to neurons. CSF-delivered human apoE entered brain via the perivascular space of penetrating arteries and flows radially around arteries, but not veins, in an isoform specific manner (apoE2 > apoE3 > apoE4). Flow of apoE around arteries was facilitated by AQP4, a characteristic feature of the glymphatic system. ApoE3, delivered by lentivirus to the choroid plexus and ependymal layer but not to the parenchymal cells, was present in the CSF, penetrating arteries and neurons. The inflow of CSF, which contains apoE, into brain and its clearance from the interstitium were severely suppressed by sleep deprivation compared to the sleep state. Thus, choroid plexus

    Full Text Available Abstract Background The physiological regulation of hepatic apoE gene has not been clarified, although the expression of apoE in adipocytes and macrophages has been known to be regulated by LXR. Methods and Results We investigated the effect of TO901317, a LXR agonist, on hepatic apoE production utilizing HepG2 cells cultured in spheroid form, known to be more differentiated than HepG2 cells in monolayer culture. Spheroid HepG2 cells were prepared in alginate-beads. The secretions of albumin, apoE and apoA-I from spheroid HepG2 cells were significantly increased compared to those from monolayer HepG2 cells, and these increases were accompanied by increased mRNA levels of apoE and apoA-I. Several nuclear receptors including LXRα also became abundant in nuclear fractions in spheroid HepG2 cells. Treatment with TO901317 significantly increased apoE protein secretion from spheroid HepG2 cells, which was also associated with the increased expression of apoE mRNA. Separation of the media with FPLC revealed that the production of apoE-rich large HDL particles were enhanced even at low concentration of TO901317, and at higher concentration of TO901317, production of VLDL particles increased as well. Conclusions LXR activation enhanced the expression of hepatic apoE, together with the alteration of lipoprotein particles produced from the differentiated hepatocyte-derived cells. HepG2 spheroids might serve as a good model of well-differentiated human hepatocytes for future investigations of hepatic lipid metabolism.

    The German market for technically matured solar-thermal systems for generating hot water is growing by 20 per cent per year, with some deviations due to incentive policies. This growth can be and is planned to be increased systematically, with following goals: A practical contribution to the Federal Government&apos;s efforts to achieve the goals regarding the protection of climate; creating future-oriented jobs; supporting ecologically sustainable ways of life and models of consumption by convincing the consumers and other target groups of the fact that it makes sense already today to start utilizing solar energy and to invest also on private basis. These targets are expected to be set up with the help of a three-year mass campaign (1999 until 2001), i.e. the campaign called &apos;&apos;Solar - na klar.&apos;&apos; (solar - of course).

    Here we present high cadence photometry taken by the Acquisition Camera on Gemini South, of a close passage by the {approx}540 km radius Kuiper belt object, (50000) Quaoar, of a r&apos; = 20.2 background star. Observations before and after the event show that the apparent impact parameter of the event was 0.&apos;&apos;019 {+-} 0.&apos;&apos;004, corresponding to a close approach of 580 {+-} 120 km to the center of Quaoar. No signatures of occultation by either Quaoar&apos;s limb or its potential atmosphere are detectable in the relative photometry of Quaoar and the target star, which were unresolved during closest approach. From this photometry we are able to put constraints on any potential atmosphere Quaoar might have. Using a Markov chain Monte Carlo and likelihood approach, we place pressure upper limits on sublimation supported, isothermal atmospheres of pure N{sub 2}, CO, and CH{sub 4}. For N{sub 2} and CO, the upper limit surface pressures are 1 and 0.7 {mu}bar, respectively. The surface temperature required for such low sublimation pressures is {approx}33 K, much lower than Quaoar&apos;s mean temperature of {approx}44 K measured by others. We conclude that Quaoar cannot have an isothermal N{sub 2} or CO atmosphere.

    This report on behalf of the Swiss Federal Office of Energy (SFOE) describes the achievements made in a project carried out at the Institute of Microelectronics (IMT) in Neuchatel, Switzerland. The project, whose goal was to demonstrate the potential of tandem cells consisting of a combination of micro-crystalline and amorphous solar cells, has spawned world-wide interest and also initiated much research into the use of VHF-GD (Very High Frequency Glow-discharge) techniques to deposit thin films. Individual results achieved at IMT including those from investigations into micro-crystalline structures and textures and their absorption enhancement effects, electronic transport, improvement of open-circuit voltage, deposition rates, patterning techniques and increasing stabilised efficiencies are listed. A first Micromorph 23.6 cm{sup 2} mini-module using an integrated electric series connection concept is mentioned and advances in the IMT&apos;s infrastructure and facilities are described.

    Evaluate patients&apos; intraoperative experience of percutaneous vertebroplasty (PV) performed without general anaesthesia in order to assess the feasibility of local anaesthesia and simple analgesic medication as pain control protocol. Ninety-five patients who underwent single-site PV were consecutively included in the study between 2011 and 2013. Each procedure was achieved under local anaesthesia and perfusion of paracetamol, tramadol and dolasetron, with combined CT and fluoroscopy guidance. Numeric pain scale (NPS) was collected before, during and after intervention. After intervention, patients were asked to evaluate their experience as &apos;&apos;very bad&apos;&apos;, &apos;'bad'&apos;, &apos;'fair'&apos;, &apos;'good'&apos; or &apos;&apos;very good&apos;&apos;, independently of the pain. Indications for vertebroplasty were osteopenic fractures (78 %), aggressive angiomas (13 %) and somatic tumours (9 %). In 76 % of cases, patients&apos; experience was described as &apos;&apos;very good&apos;&apos; (44 %) or &apos;'good'&apos; (32 %), whereas 19 % described it as &apos;'fair'&apos; and 5 % as &apos;&apos;very bad&apos;&apos;. Mean operative NPS was 5.5. After intervention, NPS was significantly lower with a decrease of 4.5 points. No differences were found according to the localization, type of lesion, age or sex either in terms of experience or NPS. Percutaneous vertebroplasty is feasible under local anaesthesia alone, with a very good or good experience in 76 % of the patients. (orig.)

    Bouveret&apos;s syndrome is a rare disease entity manifested by the formation of a cholecystoduodenal or choledochoduodenal fistula with passage of a gallstone into the duodenal bulb and subsequent obstruction of the gastric outlet. To date, no report of this entity using computed tomographic (CT) imaging is available. This article presents a case of Bouveret&apos;s syndrome with the classic findings on upper gastrointestinal (GI) tract series and a description of the CT manifestations. The literature is reviewed with discussion of the diagnostic approach to patients with Bouveret&apos;s syndrome.

    Cerebral glucose metabolism was evaluated in patients with either Wernicke&apos;s (N = 7), Broca&apos;s (N = 11), or conduction (N = 10) aphasia using /sup 18/F-2-fluoro-2-deoxy-D-glucose with positron emission tomography. The three aphasic syndromes differed in the degree of left-to-right frontal metabolic asymmetry, with Broca&apos;s aphasia showing severe asymmetry and Wernicke&apos;s aphasia mild-to-moderate metabolic asymmetry, while patients with conduction aphasia were metabolically symmetric. On the other hand, the three syndromes showed the same degree of metabolic decline in the left temporal region. The parietal region appeared to separate conduction aphasia from both Broca&apos;s and Wernicke&apos;s aphasias. Common aphasic features in the three syndromes appear to be due to common changes in the temporal region, while unique features were associated with frontal and parietal metabolic differences.

    The expressions &apos;calibration&apos; and &apos;external calibration&apos; appear together in the present literature of atomic spectrometry resulting in a dilemma of understanding and correct use. It is examined how the IUPAC can provide a guidance to the solution of this problem by recalling the definitions of related terms of optical, mass and X-ray atomic spectrometry techniques. The introduction and definition of these expressions in widely used text books are investigated and statistically evaluated for the articles published during the last 30 years in the periodical Spectrochimica Acta Part B. For the elimination of the literary difficulties with the use of the term &apos;calibration&apos;, attributes are proposed to express the degree of matrix matching of standards and samples.

    In this paper, &apos;massless&apos; spin-(3)/(2) fields in the de Sitter space are considered. This work is a continuation of a previous paper devoted to the quantization of the de Sitter &apos;massive&apos; spin-(3)/(2) fields. Due to the appearance of gauge invariance and an indefinite metric, the covariant quantization of the &apos;massless&apos; spin-(3)/(2) fields requires an indecomposable representation of the de Sitter group. The gauge fixing corresponding to the simplest Gupta-Bleuler structure is used, and a gauge invariant field is discussed. The field equation is obtained by using the Casimir operator of the de Sitter group. The solutions are written in terms of the coordinateindependent de Sitter plane waves. Finally, the generalized two-point function is calculated. (orig.)

    OAK B139 The postgenomic era is arriving faster than anyone had imagined--sometime during 2000 we&apos;ll have a large fraction of the human genome sequence. Heretofore, our understanding of function has come from non-industrial experiments whose conclusions were largely framed in human language. The advent of large amounts of sequence data, and of &apos;&apos;functional genomic&apos;&apos; data types such as mRNA expression data, have changed this picture. These data share the feature that individual observations and measurements are typically relatively low value adding. Such data is now being generated so rapidly that the amount of information contained in it will surpass the amount of biological information collected by traditional means. It is tantalizing to envision using genomic information to create a quantitative biology with a very strong data component. Unfortunately, we are very early in our understanding of how to &apos;&apos;compute on&apos;&apos; genomic information so as to extract biological knowledge from i t. In fact, some current efforts to come to grips with genomic information often resemble a computer savvy library science, where the most important issues concern categories, classification schemes, and information retrieval. When exploring new libraries, a measure of cataloging and inventory is surely inevitable. However, at some point we will need to move from library science to scholarship.We would like to achieve a quantitative and predictive understanding of biological function. We realize that making the bridge from knowledge of systems to the sets of abstractions that constitute computable entities is not easy. The After the Genome meetings were started in 1995 to help the biological community think about and prepare for the changes in biological research in the face of the oncoming flow of genomic information. The term &apos;&apos;After the Genome&apos;&apos; refers to a future in which complete inventories of the gene products of

    Apolipoprotein E (apoE) is an essential component of lipoprotein particles in both the brain and periphery, and exists in three isoforms in the human population: E2, E3, and E4. ApoE has numerous, well-established roles in neurobiology. Most notably, E4 is associated with earlier onset and increased risk of Alzheimer's disease (AD). Although possession of E2 is protective in the context of AD, E2 appears to confer an increased incidence and severity of posttraumatic stress disorder (PTSD). However, the biological processes underlying this link remain unclear. In this study, we began to elucidate these associations by examining the effects of apoE on PTSD severity in combat veterans, and on PTSD-like behavior in mice with human apoE. In a group of 92 veterans with PTSD, we observed significantly higher Clinician-Administered PTSD Scale and PTSD Checklist scores in E2+ individuals, as well as alterations in salivary cortisol levels. Furthermore, we measured behavioral and biological outcomes in mice expressing human apoE after a single stressful event as well as following a period of chronic variable stress, a model of combat-related trauma. Mice with E2 showed impairments in fear extinction, and behavioral, cognitive, and neuroendocrine alterations following trauma. To the best of our knowledge, these data constitute the first translational demonstration of PTSD severity in men and PTSD-like symptoms in mice with E2, and point to apoE as a novel biomarker of susceptibility, and potential therapeutic target, for PTSD.

    This report represents the final phase of Swiss Federal Office of Energy project &apos;Strategy for long-term management of city-owned real estate - the case of the City Council of Chiasso&apos;. It contains a comparative analysis of two tools for the evaluation of the potential for retrofitting and refurbishment of buildings (Retrofit Advisor and Epiqr+). By applying the two tools in parallel, it was possible to compare information and data obtained, and also to obtain indications for the evaluation of the usability of the tools. To achieve this, five buildings in the territory of the city of Chiasso were submitted to the tools for analysis. The applications have highlighted the usability of each case study. The ease of use of Retrofit Advisor has allowed the evaluation of each proposed scenario; by using the same reference system, comparable data are obtained (at indication level) to support the choice of the intervention strategy on existing buildings. In addition to the analysis of the current status, the tool Retrofit Advisor supports a structure analysis over three intervention scenarios, namely reparation, renovation, rebuild. Data entry does not require advanced knowledge of construction work, and is limited to basic characteristics. The analysis performed through Epiqr+ is more rigorous, providing a specific and detailed diagnosis on the state of deterioration of each construction element, supported by a series of intervention suggestions. The Epiqr+ tool has furthermore allowed the evaluation (within a precision range of {+-}15%) the cost of reparation/renovation works, and also the thermal energy balance of each building, based on the characteristics of their envelops. On the basis of contents criteria and cost analysis, the approach has allowed the evaluation of different options for the improvement of the buildings, from simple reparation to total rebuild. Estimates are evaluated in terms of cost, of environmental impact, and, in the case of Retrofit

    &apos;Wet and dry&apos; coolers are the result of a 4-year research programme. Theoretical fundamentals of heat transfer with and without water spraying are presented to begin with, as are the method of calculation using innovative FLUENTL software, and the experimental result. &apos;Wet and dry&apos; systems consist of one or several chillers and a water conditioning system. They function as conventional dry coolers as long as the ambient temperature is low enough to ensure the required cooling water temperature. As the ambient temperature increases, demineralised water is sprayed onto the heat exchanger surface. The system has the following advantages as compared to conventional evaporation systems: (a) Water consumption is reduced significantly as water is required only during a limited period of the year; (b) Nearly complete evaporation of the sprayed water without water circulation, i.e. no collector basin is required below the heat exchanger. (c) Environment-friendliness: No undesired plumes, no health risk (e.g. legionellosis) from open basins of warm water, no residual droplets; (d) Automatic control minimises energy and water consumption in all seasons.

    The Inspection Validation Centre (IVC) of AEA Reactor Services in the UK has begun an eighteen month programme to validate the procedures and personnel of OIS plc, the inspection agents chosen by Nuclear Electric to carry out the pre-service ultrasonic inspection of the Sizewell B Pressurized Water Reactor components assigned to the &apos;&apos;Incredibility of Failure&apos;&apos; (IoF) category. The work involves several Sizewell B primary circuit components - the steam generators, pressurizer, and primary pumps - and will consider the inspections to be applied to the circumferential and nozzle-to-shell welds, nozzle inner radii and the pump fly-wheel forging. The validation will provide independent confirmation that OIS personnel are capable of using manual and automated methods to find and size any flaws of structural concern in these components.

    Actin filament-disrupting marine macrolides are promising templates from which to design therapeutics against cancer and other diseases that co-opt the actin cytoskeleton. Typically, these macrolides form either a 1:1 or 2:1 actin-macrolide complex where their aliphatic side chain, or &apos;tail&apos;, has been reported to convey the major determinant of cytotoxicity. We now report the structure of the marine macrolide lobophorolide bound to actin with a unique 2:2 stoichiometry in which two lobophorolide molecules cooperate to form a dimerization interface that is composed entirely of the macrolide &apos;ring&apos; region, and each molecule of lobophorolide interacts with both actin subunits via their ring and tail regions to tether the subunits together. This binding mode imposes multiple barriers against microfilament stability and holds important implications for development of actin-targeting drugs and the evolution of macrolide biosynthetic enzymes.

    The cellulose industry generates huge amounts of solid waste residue called &apos;grits&apos;. These wastes have been willing over time in landfills near the mills. However, this type of disposal is not environmentally friendly and can cause degradation and environmental pollution. In addition, environmental legislation increasingly severe and the high costs of landfill have led the search for new alternatives for final disposition of this abundant waste. In this context, this study is to characterize waste grits, generated by the cellulose industry in the region of Aracruz-ES. The residue samples were characterized in terms of chemical composition, X-ray diffraction, particle size distribution and thermal analysis (DTA and TGA). The characterization of the residual &apos;grits&apos; demonstrated its potential as a feedstock for production of soil-cement bricks. (author)

    This article studies the hygro-thermal behaviour of two traditional underground wine cellars from Morcuera (Soria, Spain). The differences between them are analyzed and our hypothesis is that one of these constructions is better than the other for the ageing of wines. The hypothesis takes into consideration the existence of a temperature difference of over 20{sup o}C between them as a basis for reaching the aforementioned conclusion. However, the relative humidity inside both of them is 100%, which could pose problems if the presence of mould is not controlled. This study is based on fieldwork for the inventory and cataloguing of traditional agrarian constructions in the &apos;&apos;Tierras Sorianas&apos;&apos; area. The objective of this investigation is to highlight some advantages of traditional building techniques over modern construction practices from the energy-saving viewpoint. (author)

    Energy Dispersive Reflectometry (EDR) beamline at BESSY II provides &apos;'white'&apos; X-rays in the useful energy range of 5apos;'trivial'&apos; samples to determine the so called apparatus function. In addition I measured coherent reflectivity maps from thin film of highly scattering material of Pt with high atom number, Z=78 and patterned semiconducting surface like a GaAs surface grating which provides a certain periodicity in the measured scattering intensity. Finally I measured the surface speckles from a spatially confined Si wafer under the constraint that the size of the sample is smaller than the footprint of the incoming beam at the sample position. To reconstruct surface morphology from coherent reflectivity data is a typical inverse problem. Conventional phase retrieval algorithms like Gerchberg-Saxton (GS) algorithm, error reduction (ER) algorithm, hybrid input-output (HIO) algorithm are used in earlier work by other authors. I modified the conventional GS algorithm and ER algorithm which takes into account the additional Fresnel propagator term and also the illumination function at the sample position. I tested the modified algorithm successfully for a model surface in the form of a surface grating. I used the modified algorithm to reconstruct surface morphology from various static speckle measurements I performed at EDR beamline. The surface profiles reconstructed for different samples from the data at different energies (below the critical energy for the material at a particular incident angle) show almost the same roughness behavior for surface height with mean roughness of {proportional_to}1 nm. With the static speckle data I measured I could retrieve a one-dimensional picture of the sample surface with spatial

    This short article takes a look at the &apos;2000-Watt per person&apos; concept initially developed at the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland, in 1998. The author is of the opinion that the concept is not utopian but a vision that can be realised - providing it is accepted socially and that politics can implement it. Further work on the concept done at the ETH over the years is listed and commented on. A diagram provides an overview of energy resources, energy transformation and energy flows to final energy consumption. The question as to if the realisation of such a &apos;2000-Watt&apos;-society is actually necessary is posed.

    Advanced Test Reactor (ATR) Cycle 153B-1 was a 14-day, high-power, powered axial locator mechanism (PALM) operating cycle that completed on April 12, 2013. Cycle 153B-1 was a typical operating cycle for the ATR, and did not result in any unusual plant transients. ATR was started up and shut down as scheduled. The PALM drive physically moves the selected experiments into and out of the core to simulate reactor startup and heat up, and shutdown and cooldown transients, while the reactor remains in steady-state conditions. However, after the cycle was over, when the fuel elements were removed from the core and inspected, several thousand flow-assisted erosion pits and &apos;'horseshoeing'&apos; defects were readily observed on the surface of the several YA-type fuel elements (these are aluminum &apos;'dummy'&apos; plates that contain no fuel). In order to understand these erosion phenomena, a thermal-hydraulic model of coolant channel 20 on a YA-M fuel element was generated. The boundaries of the model were the aluminum EE plate of a YA-M fuel element and a beryllium reflector block with 13 horizontal saw cuts which represented regions of zero flow. The heat generated in fuel plates 1 through 18 was modeled to be passing through the aluminum EE plate. The coolant channel 20 width was set at 0.058 in. (58 mils). It was established that the horizontal saw cuts had a significant effect on the temperature of the coolant. The flow, which was expected to vary linearly with gradual heating of the coolant as it passed through the channel, was extremely turbulent. The temperature rise, which was expected to be a smooth &apos;'S'&apos; curve, was represented by a series temperature rise &apos;'humps,'&apos; which occurred at each horizontal saw cut in the beryllium reflector block. Each of the 13 saw cuts had a chamfered edge which resulted in the coolant flow being re-directed as a jet across the coolant channel into the surface of the

    In situ preserved latex (&apos;'Affenhaar'&apos;) has long been known from some of the Middle Eocene lignites of Central Germany. Now, for the first time, the occurrence of bark with latex canals still in situ has been studied in detail in the former mining area of the Geiseltal. Affenhaar is found in both massive matrix-dominated lignites and interbedded clastics, representing sub-autochthonous and reworked material, respectively. Palynological studies of Affenhaar-bearing sections reveal a highly diverse assemblage of spores and pollen, but none of the pollen taxa is obviously correlated to the occurrence of Affenhaar. A significant herbaceous component has been recognized in the pollen record in addition to those taxa mainly derived from trees. (author)

The objective set by the IGU consisted in studying the generic thema in gas markets development for the less developed countries, in the developing countries with intermediate revenue as well as in the transitional economy countries. The first study group devoted his works to the problematic analysis of natural gas in the less developed countries, those where the GNP per capita is very low and the internal markets of which are little or non dynamic. This analysis has been developed in a certain number of countries rather representative of their respective region: Angola, Cameroon and Cote d&apos;Ivoire for sub-Saharian Africa, Bangladesh and Vietnam for Asia. The second study group analysed the changes in transitional economy countries (Baltic, countries in Central Europe and Ukraine) and their different consequences on gas industry. These countries apply gas industry reforms which are not implemented at the same rate more especially as they belong to a huge and very contrasted geographic region. The third study group devoted his works to the analysis of intensified conditions in the use of natural gas in the developing countries with intermediate revenue. He also examined the feasibility of an economic development in gas distribution networks in large cities. Two important issues focused his attention: financing and technology transfer. (author)

    1983-01-01

    This paper presents a method for analyzing the seismic response of a flat bottomed cylindrical liquid storage tank to vertical earthquake excitation. Here, vertical earthquake acceleration is considered to correspond to an increase in the density of a stored liquid. Taking into account the vertical and horizontal earthquake loads, hydrostatic pressure, and considering restrictive moment and shear forces at shell-bottom welded joint, the author has calculated circumferential and longitudinal stresses. These are combined to more accurately approximate the stresses at the base shell course. The calculated result closely conforms to the actual damage, termed &apos;'elephant&apos;s foot,&apos;&apos; observed in the fuel storage tanks damaged in the Tangshan earthquake. This result shows that the &apos;'elephant&apos;s foot&apos;&apos; phenomenon is not caused by buckling of the tank shell due to longitudinal compressive stresses resulting from horizontal earthquake acceleration, but rather by the combined stresses in the base shell course of the storage tank exceeding the yield strength of the shell course material. The effect due to vertical earthquake load is more than the effect from the horizontal load. Finally, some earthquake resistant methods to prevent the &apos;'elephant&apos;s foot&apos;&apos; phenomenon are suggested by the author.

    Schnitzler syndrome is characterized by chronic urticaria, monoclonal gammopathy, and a risk of developing lymphoproliferative disorders. Patients frequently present with bone pain, fever, arthralgia, and lymphadenopathy. The purpose of this study is to retrospectively review and evaluate potentially attributable imaging abnormalities in a series of patients with clinically diagnosed Schnitzler syndrome. Clinical and pathological chart review identified 22 patients meeting Strasbourg criteria for Schnitzler syndrome. Imaging of these patients was retrospectively reviewed by a musculoskeletal radiologist and a radiology fellow to determine and characterize significant &apos;'positive'&apos; findings that could potentially be attributed to their primary disease process. Evidence of abnormal bone remodeling was present in 64 % (14/22) of patients with 40 bone abnormalities. Lesions were predominantly or entirely sclerotic and most commonly involved the distal femora (n = 11), proximal tibiae (nine), and innominate bones (six). Patterns of involvement were variable, but typically eccentrically intramedullary, cortical, and juxta-articular. Skeletal surveys and targeted radiographs identified only 37 % (10/27) of abnormal bones subsequently &apos;'positive'&apos; by additional modalities. PET and bone scans were all positive in patients with bone sclerosis (13/13 and 17/17 bone sites, respectively). Schnitzler syndrome often presents with characteristic osteosclerosis, most commonly around the knees and in the pelvis. In patients with a suggestive clinical history, the radiologist could direct an appropriate imaging strategy or might to be the first to suggest the diagnosis. Bone scan may be the most appropriate initial screening tool in suspected cases. (orig.)

    In cases of head and neck cancer, surgical advances in combination with radiotherapy (RT) have brought an increase in patients&apos; probability of cure. RT is widely used and aims to destroy cancer cells in order to reduce or eliminate a malignant tumor. However, RT also causes major changes in patients&apos; quality of life during and after treatment. The current study aims to evaluate the side effects of RT in patients with head and neck cancer and its influence on quality of life. The study population included head and neck cancer patients submitted to RT at the University of Sao Paulo Hospital in Ribeirao Preto, Brazil. Data were collected with the FACT H and N instrument and McMaster University&apos;s Questionnaire for head and neck RT and submitted to quantitative statistical analysis using SPSS (Statistical Package for the Social Sciences). The main side effects of RT that affected physical quality of life were related to salivation and nutritional problems, while the predominant emotional problems were depression and anxiety. (author)

The National Control Center for Medical Devices as national regulator entity for the control and supervision of the medical devices of the National Health System is the responsible for it implementation. This paper presents the preliminary results of the execution of the PNAC in teletherapy services with isotopic units of {sup 60} Co. The audits were carried out according to the methodology settled down in the normalized procedure of operation of the PNAC. The physical aspects related with the treatment were audit, such as: the installation and unit&apos;s security, treatment unit&apos;s mechanical and dosimetric aspects and organizational aspects of the institution quality assurance program. Also were carried out, in the clinical aspect, verifications of cases type planned by the qualified personnel of the service. The results corresponding to the determination of the reference dose for each institution were compared with those obtained in a postal audit with the International Atomic Energy Agency. These first audits allowed to evaluate the performance of the institution&apos;s program of quality assurance and a feedback for the setting about to the PNAC. (author)

    The athlete&apos;s heart is commonly characterized by an increase in left ventricular mass because of an increase in the left ventricular diastolic cavity dimensions or wall thickness or both. Endurance exercise also induces numerous cardiovascular adaptations, including increased vagal tone. However, the sympathetic function has not yet been precisely elucidated, so the present study evaluated cardiac sympathetic nerve function from metaiodobenzylguanidine (MIBG) images obtained 15 and 180 min after the injection of {sup 123}I-MIBG at a dose of 111MBq. The ratio of heart/mediastinum count (H/M) and the washout rates of {sup 123}I-MIBG (WR) were calculated in 25 consecutive patients who were athletes (aged 52{+-}13 years) and 23 normal subjects. There was a significant difference in the H/M between the athletic and normal hearts (2.3{+-}0.3 vs 2.6{+-}0.3, p<0.01, Scheffe&apos;s test). An increased WR was observed in the athletes group when compared with the normal group (34{+-}4 vs 28{+-}3, p<0.01), and there was a significant correlation between WR and the left ventricular mass index (r=0.578, p<0.01). Prolonged exercise training may alter cardiac sympathetic nerve function, which can be detected by MIBG imaging. (author)

    The author describes the decline of Venezuela&apos;s oil industry as well as President Chavez&apos; reaction to Venezuela&apos;s budgetary crisis. Politicization, falling investment and the obligation to take upon itself a plethora of social spending have left national oil company Petroleos de Venezuela, S.A. unable to produce efficiently and maintain production levels. Falling oil production and lower oil prices have in turn left president Hugo Chavez unable to spread the wealth to Venezuela&apos;s poor and he is searching desperately for ways to extract yet more from Venezuela&apos;s dysfunctional economy. As funds run out, Venezuela&apos;s expensive foreign policy, supporting regional allies, in particular Cuba, and seeking to export anywhere but the United States, proves overly expensive. Venezuela&apos;s impoverished masses, still supportive of Chavez during February&apos;s elections, may become less so as funds for social programmes run out. For Chavez it is a time for making choices... otherwise the people of Venezuela will choose for him. [Dutch] De auteur beschrijft de teruggang van de olie-industrie van Venezuela en de reacties van president Chavez op de budgettaire crisis in Venezuela. Politisering, dalende investeringen en de verplichtingen m.b.t. de overvloed aan sociale uitgaven zorgen er voor dat de nationale oliemaatschappij Petroleos de Venezuela niet in staat is om efficient te produceren en de productie op peil te houden. Dalende olie-productie en lagere olieprijzen zorgen er ook voor dat de president niet in staat is om de rijkdom te verdelen over de armen in Venezuela. Hij is op zoek naar manieren om meer te halen uit de slecht functionerende economie. Zijn dure buitenlandse Venezuela beleid, onder meer door ondersteuning van regionale bondgenoten, in het bijzonder Cuba, en het zoeken naar export mogelijkheden, behalve naar de USA, pakt fiancieel gezien slecht uit. De verarmde massa&apos;s van Venezuela steunden Chavez nog in de verkiezingen in

    To determine the metaphyseal changes occurring in Legg-Calve-Perthes(LCP) disease using MRI. Between 1992 to 1999, 80 LCP patients (87 hips) underwent MR imaging and plain radiography. All MR images were reviewed, bone marrow signal intensity, the size and locatiion of the metaphyseal cyst and its epiphyseal necrosis grade determined. Metaphyses were abnormal in 43hips (49%), while bone marrow edema was present in 28 (32%) and a metaphyseal cyst in 30 (34%). Metaphyseal cysts were classified as either &apos;true&apos; (n=9) or &apos;false&apos; (n=21) according to the enhancement pattern. The maximum diameters of true and false cysts were 1.1{+-}0.3 cm and 1.1{+-}0.4 cm, respectively. Their most commom location was the anterior column; a true cyst occurred there in 7cases (78%), and false cyst in 16 (76%). Using the Waldenstrom classification, seven of the nine hips wih a true cyst (78%), were found to be at the avascular stage and 15 of the 21 with a false cyst (71%) were at the fragmentation stage. Seven of these nine (78%) and 19 of these 21 (90%) were Catterall grade IV. According to the findings of MR imaging, the metaphyseal changes occurring in LCP disease were bone marrow edema and metaphyseal cyst. This latter was visualized mainly in the anterior column and severely affected hip, and was classified as &apos;true&apos; or &apos;false&apos;.

  12. The cathelicidin protein CRAMP is a potential atherosclerosis self-antigen in ApoE(-/- mice.

    Directory of Open Access Journals (Sweden)

    Peter M Mihailovic

    Full Text Available Auto-immunity is believed to contribute to inflammation in atherosclerosis. The antimicrobial peptide LL-37, a fragment of the cathelicidin protein precursor hCAP18, was previously identified as an autoantigen in psoriasis. Given the reported link between psoriasis and coronary artery disease, the biological relevance of the autoantigen to atherosclerosis was tested in vitro using a truncated (t form of the mouse homolog of hCAP18, CRAMP, on splenocytes from athero-prone ApoE(-/- mice. Stimulation with tCRAMP resulted in increased CD8+ T cells with Central Memory and Effector Memory phenotypes in ApoE(-/- mice, differentially activated by feeding with normal chow or high fat diet. Immunization of ApoE(-/- with different doses of the shortened peptide (Cramp resulted in differential outcomes with a lower dose reducing atherosclerosis whereas a higher dose exacerbating the disease with increased neutrophil infiltration of the atherosclerotic plaques. Low dose Cramp immunization also resulted in increased splenic CD8+ T cell degranulation and reduced CD11b+CD11c+ conventional dendritic cells (cDCs, whereas high dose increased CD11b+CD11c+ cDCs. Our results identified CRAMP, the mouse homolog of hCAP-18, as a potential self-antigen involved in the immune response to atherosclerosis in the ApoE(-/- mouse model.

  1. First `Winged&apos; and `X&apos;-shaped Radio Source Candidates

    Energy Technology Data Exchange (ETDEWEB)

    Cheung, C.C.

    2007-01-22

    A small number of double-lobed radio galaxies (17 from our own census of the literature) show an additional pair of low surface brightness &apos;'wings'&apos;, thus forming an overall &apos;'X'&apos;-shaped appearance. The origin of the wings in these radio sources is unclear. They may be the result of back-flowing plasma from the currently active radio lobes into an asymmetric medium surrounding the active nucleus, which would make these ideal systems in which to study thermal/non-thermal plasma interactions in extragalactic radio sources. Another possibility is that the wings are the aging radio lobes left over after a (rapid) realignment of the central supermassive black-hole/accretion disk system due perhaps to a merger. Generally, these models are not well tested; with the small number of known examples, previous works focused on detailed case studies of selected sources with little attempt at a systematic study of a large sample. Using the VLA-FIRST survey database, we are compiling a large sample of winged and X-shaped radio sources for such studies. As a first step toward this goal, an initial sample of 100 new candidate objects of this type are presented in this paper. The search process is described, optical identifications from available literature data, and basic radio data are presented. From the limited resolution FIRST images ({approx} 5&apos;&apos;), we can already confidently classify a sufficient number of these objects as having the characteristic wing lengths >80% of the active lobes to more than double the number of known X-shaped radio sources. We have also included as candidates, radio sources with shorter wings (<80% wing to lobe length ratios), or simply &apos;'winged'&apos; sources, as it is probable that projection effects are important. Finally, among the candidates are four quasars (z=0.37 to 0.84), and several have morphologies suggestive of Fanaroff-Riley type-I (low-power) radio galaxies. While followup

    Humans possess three major isoforms of the apolipoprotein E (ApoE) gene encoded by three alleles: ApoE ɛ2 (ApoE2), ApoE ɛ3 (ApoE3), and ApoE ɛ4 (ApoE4). It is established that the three ApoE isoforms confer differential susceptibility to Alzheimer's disease (AD); however, an in-depth molecular understanding of the underlying mechanisms is currently unavailable. In this study, we examined the cortical proteome differences among the three ApoE isoforms using 6-month-old female, human ApoE2, ApoE3, and ApoE4 gene-targeted replacement mice and two-dimensional proteomic analyses. The results reveal that the three ApoE brains differ primarily in two areas: cellular bioenergetics and synaptic transmission. Of particular significance, we show for the first time that the three ApoE brains differentially express a key component of the catalytic domain of the V-type H+-ATPase (Atp6v), a proton pump that mediates the concentration of neurotransmitters into synaptic vesicles and thus is crucial in synaptic transmission. Specifically, our data demonstrate that ApoE2 brain exhibits significantly higher levels of the B subunit of Atp6v (Atp6v1B2) when compared to both ApoE3 and ApoE4 brains, with ApoE4 brain exhibiting the lowest expression. Our additional analyses show that Atp6v1B2 is significantly impacted by aging and AD pathology and the data suggest that Atp6v1B2 deficiency could be involved in the progressive loss of synaptic integrity during early development of AD. Collectively, our findings indicate that human ApoE isoforms differentially modulate regulatory mechanisms of bioenergetic and synaptic function in female brain. A more efficient and robust status in both areas-in which Atp6v may play a role-could serve as a potential mechanism contributing to the neuroprotective and cognition-favoring properties associated with the ApoE2 genotype.

    Fibrinogen residue B{beta}432Asp is part of hole &apos;b&apos; that interacts with knob &apos;B,&apos; whose sequence starts with Gly-His-Arg-Pro-amide (GHRP). Because previous studies showed B{beta}D432A has normal polymerization, we hypothesized that B{beta}432Asp is not critical for knob &apos;B&apos; binding and that new knob-hole interactions would compensate for the loss of this Asp residue. To test this hypothesis, we solved the crystal structure of fragment D from B{beta}D432A. Surprisingly, the structure (rfD-B{beta}D432A+GH) showed the peptide GHRP was not bound to hole &apos;b.&apos; We then re-evaluated the polymerization of this variant by examining clot turbidity, clot structure, and the rate of FXIIIa cross-linking. The turbidity and the rate of - dimer formation for B{beta}D432A were indistinguishable compared with normal fibrinogen. Scanning electron microscopy showed no significant differences between the clots of B{beta}D432A and normal, but the thrombin-derived clots had thicker fibers than clots obtained from batroxobin, suggesting that cleavage of FpB is more important than &apos;B:b&apos; interactions. We conclude that hole &apos;b&apos; and &apos;B:b&apos; knob-hole binding per se have no influence on fibrin polymerization.

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

    Experimental data suggest that apolipoprotein (apo) C-II and C-III regulate triglyceride-rich lipoprotein (TRL) metabolism, but there are limited studies in humans. We investigated the metabolic associations of TRLs with apoC-II and apoC-III concentrations and kinetics in women. The kinetics of plasma apoC-II, apoC-III and very low-density lipoprotein (VLDL) apoB-100 and triglycerides were measured in the postabsorptive state using stable isotopic techniques and compartmental modelling in 60 women with wide-ranging body mass index (19·5-32·9 kg/m(2) ). Plasma apoC-II and apoC-III concentrations were positively associated with the concentrations of plasma triglycerides, VLDL1 - and VLDL2 -apoB-100 and triglyceride (all P triglyceride concentration and VLDL1 triglyceride PR, while apoC-II fractional catabolic rate (FCR) was positively associated with VLDL1 triglyceride FCR (all P triglyceride kinetics. ApoC-III PR, but not FCR, was positively associated with VLDL1 triglyceride, and VLDL2 -apoB-100 and triglyceride concentrations (all P triglyceride kinetics. In multivariable analysis, including homoeostasis model assessment score, menopausal status and obesity, apoC-II concentration was significantly associated with plasma triglyceride, VLDL1 -apoB-100 and VLDL1 triglyceride concentrations and PR. Using the same multivariable analysis, apoC-III was significantly associated with plasma triglyceride and VLDL1 - and VLDL2 -apoB-100 and triglyceride concentrations and FCR. In women, plasma apoC-II and apoC-III concentrations are regulated by their respective PR and are significant, independent determinants of the kinetics and plasma concentrations of TRLs. © 2016 Stichting European Society for Clinical Investigation Journal Foundation.

    Using 232 fb{sup -1} of data collected by the BABAR detector, the {Xi}&apos;{sub c}{sup +} and {Xi}&apos;{sub c}{sup 0} baryons are reconstructed through the decays: {Xi}&apos;{sub c}{sup +} {yields} {Xi}{sub c}{sup +}{gamma} and {Xi}&apos;{sub c}{sup 0} {yields} {Xi}{sub c}{sup 0}{gamma}, where {Xi}{sub c}{sup +} {yields} {Xi}{sup -}{pi}{sup +}{pi}{sup +} and {Xi}{sub c}{sup 0} {yields} {Xi}{sup -} {pi}{sup +}. By measuring the efficiency-corrected yields in different intervals of the center-of-mass momentum, the production rates from B decays and from the continuum are extracted. For production from B decays, the branching fractions are found to be {Beta}(B {yields} {Xi}&apos;{sub c}{sup +}X) x {Beta}({Xi}{sub c}{sup +} {yields} {Xi}{sup -}{pi}{sup +}{pi}{sup +}) = [1.69 {+-} 0.17 (exp.) {+-} 0.10 (model)] x 10{sup -4} and {Beta}(B {yields} {Xi}&apos;{sub c}{sup 0}X) x {Beta} {Xi}{sub c}{sup 0} {yields} {Xi}{sup -} {pi}{sup +} = [0.67 {+-} 0.07 (exp.) {+-} 0.03 (model)] x 10{sup -4}. For production from the continuum the cross-sections are found to be {sigma}(e{sup +}e{sup -} {yields} {Xi}&apos;{sub c}{sup +}X) x {Beta}({Xi}{sub c}{sup +} {yields} {Xi}{sup -} {pi}{sup +}{pi}{sup +}) = 141 {+-} 24 (exp.) {+-} 19 (model) fb and {sigma}(e{sup +}e{sup -} {yields} {Xi}&apos;{sub c}{sup 0}X) x {Beta}({Xi}{sub c}{sup 0} {yields} {Xi}{sup -} {pi}{sup +}) = 70 {+-} 11 (exp.) {+-} 6 (model) fb.

    imaging techniques need to be validated in prospective clinical trials assessing the SMM to multiple myeloma transition, with the aim of enabling appropriate management decisions. Efforts are also needed to improve the costs and availability of whole-body MRI and/or FDG PET/CT, in order to facilitate their widespread adoption as first-line detection modalities. Future clinical trials of therapeutic agents using earlier detection strategies will have to be carefully designed and take into consideration the risk of lead-time and length-time biases, which might falsely demonstrate longer overall survival. The English full text version of this article is available at SpringerLink (under &apos;'Supplemental'&apos;). (orig.) [German] Aktuelle klinische Studien sprechen fuer eine Therapie des &apos;&apos;smoldering multiple myeloma&apos;&apos; (SMM) mit hohem Progressionsrisiko schon bei der Diagnosestellung und nicht erst zum Zeitpunkt der Progression in ein symptomatisches multiples Myelom (MM). Die Frueherkennung einer Knochen- und/oder Knochenmarkbeteiligung durch entsprechende sensitive Bildgebungsverfahren kann zur Ermittlung von SMM-Patienten mit hohem Risiko fuer eine Progression beitragen. Nach aktuellen Konsensusleitlinien (2011) ist die Roentgenuntersuchung des Skeletts ein Grundpfeiler der Beurteilung einer Knochenbeteiligung bei Diagnosestellung und in Verlaufskontrollen wegen eines SMM. Jedoch hat die Roentgenuntersuchung des Skeletts eine geringe Sensitivitaet fuer Knochenlaesionen und liefert keine Informationen zu Knochenmarkveraenderungen. Moderne bildgebende Verfahren wie die Fluordeoxyglukose-Positronenemissionstomographie-Computertomographie (FDG-PET-CT) und die Magnetresonanztomographie (MRT) liefern zusammen mit innovativen Funktionsuntersuchungen eine bessere Einschaetzung allgemeiner Veraenderungen im Knochenmark- und im Knochenkompartiment. Mit diesen Verfahren kann die beginnende Progression vom SMM zum MM quantitativ objektiviert werden

    The evaluation of the environmental quality objective &apos;A Safe Radiation Environment&apos; is a contribution to the Environmental Objective Council&apos;s assessment of progress towards the national environmental quality objectives. The report describes and evaluates the radiation environment in Sweden, the regulatory instruments, measures carried out and the monitoring programmes. Furthermore, the possibility of achieving the objective and its interim targets is evaluated. New measures and means of control are proposed. The proposals are directed to the government and Parliament, national authorities and other stakeholders in society. The Swedish Radiation Protection Authority (SSI) considers it possible to achieve the objective, but additional efforts are required to ensure success. Environmental monitoring, research on health effects of radiation and supervision are still important areas. Intensified efforts will be needed to change attitudes towards suntanning. Changes in the formulation of the objective and its interim targets are suggested. Today only protection against radiation in the external environment is covered by the objective. Radiation protection work has to consider all. SSI therefore suggests that the objective should extend to include workplaces and indoor environment. For the three interim targets included in &apos;A Safe Radiation Environment&apos;, changes are suggested for the interim targets for radioactive substances and electromagnetic fields. No change is suggested for the interim target for skin cancer

    Full Text Available PURPOSE: To evaluate the efficacy of radiotherapy (RT with total dose of 20 Gy (RT 20 Gy in the treatment of Graves' ophthalmopathy. METHODS: A systematic review and meta-analysis of randomized controlled trials was performed comparing RT 20 Gy with or without glucocorticoid to clinical treatments for Graves' ophthalmopathy. The MEDLINE, EMBASE, Cochrane Library databases and recent relevant journals were searched. Relevant reports were reviewed by two reviewers. Response to radiotherapy was defined as clinical success according to each trial. We also evaluated the quality of life and whether RT to produce fewer side effects than other treatments. RESULTS: A total of 8 randomized controlled trials (439 patients were identified. In the subgroup analysis, the overall response to treatment rates was better for: RT 20 Gy plus glucocorticoid vs glucocorticoids alone, OR=17.5 (CI95% 1.85-250, p=0.04, RT 20 Gy vs sham RT, OR= 3.15 (CI95%1.59-6.23, p=0.003 and RT 20Gy plus intravenous glucocorticoid vs RT 20Gy plus oral glucocorticoid, OR=4.15(CI95% 1.34-12.87, p=0.01. There were no differences between RT 20 Gy versus other fractionations and RT 20 Gy versus glucocorticoid alone. RT 20 Gy with or without glucocorticoids showed an improvement in diplopia grade, visual acuity, optic neuropathy, lid width, proptosis and ocular motility. No difference was seen for costs, intraocular pressure and quality of life. CONCLUSION: Our data have shown that RT 20 Gy should be offered as a valid therapeutic option to patients with moderate to severe ophthalmopathy. The effectiveness of orbital radiotherapy can be increased by the synergistic interaction with glucocorticoids. Moreover, RT 20 Gy is useful to improve a lot of ocular symptoms, excluding intraocular pressure, without any difference in quality of life and costs.OBJETIVO: Avaliar a eficácia da radioterapia (RT com dose total de 20 Gy (RT 20 Gy no tratamento da oftalmopatia de Graves.

    The reconstitution of the thermal history of a sedimentary basin depends on its burial history. The aim of this work is to correlate the informations supplied by sequential stratigraphy with those supplied by the transformation kinetics of organic matter. The &apos;'TherMO'S'&apos; model has been built in order to determine the paleo-burials, paleo-porosities, the paleo-thermal conductivities, the paleo-thermal gradients, the paleo-temperatures, the paleo-thermal energies and the paleo-Tmax. To do this, a heat flux at the borehole scale is imposed by the user and adjusted thanks to the Tmax obtained by Rock-Eval pyrolysis. The flux is assumed to be constant with time. A W-E section crosses the Paris basin from Rambouillet to Francheville. TherMO&apos;S has been tested and validated for 20 boreholes of this section localized in the Paris block. This study is made at the sequential scale (time interval comprised between 1-5 Ma). The reconstitution of the thermal history of the basin is first of all function of the definition of the boundaries of the sequences included in the stratigraphic database. A thermal database has been obtained for each sequence and each age of the Paris basin which fulfills the expectations of the national program of hydrological researches (PNRH). Simulations have permitted to show a lateral decay of the heat flux from Rambouillet up to the &apos;Trou aux Loups&apos; area. In parallel, the thermal paleo-gradients decrease with time for each borehole. These results put forward the consequences of the thermal subsidence (characteristic of intra-cratonic basins like the Paris basin) on the evolution of the thermal properties linked with the burial history of each stratigraphic horizon. Finally, the simulations have permitted to distinguish three thermal events during the Pliensbachian, during the Dogger-Malm, and during the end of lower Cretaceous-beginning of upper Cretaceous.

    South Africa is a country which is increasingly seen as a potential new nuclear market that promises to give one or more of the world&apos;s major nuclear vendors an important foothold on the continent. South Africa has two pressurised water reactors operating at the Koeberg nuclear plant. The 930-megawatt (MW) first unit entered commercial operation in July 1984, followed by the second (900 MW) unit in November 1985. These are the only commercial nuclear power plants on the continent of Africa. South Africa&apos;s updated draft integrated resources plan (IRP) for electricity for 2010-30, for which a public consultation period ended in February of this year, included revised projections. that suggested no new nuclear baseload capacity would be needed &apos;until after 2025&apos;. A capacity &apos;at least 6,600 MW less&apos; is required in terms of reliable overall generating capacity in 2030. However great South Africa&apos;s demand for a clean, affordable and reliable supply of nuclear-generated electricity, coupled with the economic benefits such developments will bring, investors also understand the potential for nuclear growth in this part of the world.

    This report documents the ASC/ATDM Kokkos deliverable "Production Portable Dy- namic Task DAG Capability." This capability enables applications to create and execute a dynamic task DAG ; a collection of heterogeneous computational tasks with a directed acyclic graph (DAG) of "execute after" dependencies where tasks and their dependencies are dynamically created and destroyed as tasks execute. The Kokkos task scheduler executes the dynamic task DAG on the target execution resource; e.g. a multicore CPU, a manycore CPU such as Intel&apos;s Knights Landing (KNL), or an NVIDIA GPU. Several major technical challenges had to be addressed during development of Kokkos&apos; Task DAG capability: (1) portability to a GPU with it&apos;s simplified hardware and micro- runtime, (2) thread-scalable memory allocation and deallocation from a bounded pool of memory, (3) thread-scalable scheduler for dynamic task DAG, (4) usability by applications.

    Nowadays, percutaneous vertebroplasty, or its evolution kyphoplasty, is a valid therapeutic option for the management of severe back pain, caused by vertebral compression fractures (1). They are minimally invasive, radiologically guided interventional procedures, which involve the injection of polymethylmethacrylate (PMMA) into the fractured vertebral body. The injection process was monitored continuously, under a fluoroscopic control in the lateral plane (2). Ideally, the injection should be completed in 5 to 6 minutes and before the PMMA becomes too viscous to allow reinsertion of the stylus. This is not always possible, but is preferred to avoid the risk of leaving a &apos;needle castor a &apos;cement tail&apos;, within the soft tissues, as the needle is removed with the adherent cement (Fig. 1). In the event that the reinsertion cannot be achieved, great care should be taken to dislodge the adherent PMMA cement before extracting the needle from the vertebral body (3).

    Boundary-value problems involve two dependent variables: a potential function, and a stream function. They can be approached in two mutually independent ways. The first, introduced by Laplace, involves spatial gradients at a point. Inspired by Faraday, Maxwell introduced the other, visualizing the flow domain as a collection of flow tubes and isopotential surfaces. Boundary-value problems intrinsically entail coupled treatment (or, equivalently, optimization) of potential and stream functions Historically, potential theory avoided the cumbersome optimization task through ingenious techniques such as conformal mapping and Green&apos;s functions. Laplace&apos;s point-based approach, and Maxwell&apos;s global approach, each provides its own unique insights into boundary-value problems. Commonly, Laplace&apos;s equation is solved either algebraically, or with approximate numerical methods. Maxwell&apos;s geometry-based approach opens up novel possibilities of direct optimization, providing an independent logical basis for numerical models, rather than treating them as approximate solvers of the differential equation. Whereas points, gradients, and Darcy&apos;s law are central to posing problems on the basis of Laplace&apos;s approach, flow tubes, potential differences, and the mathematical form of Ohm&apos;s law are central to posing them in natural coordinates oriented along flow paths. Besides being of philosophical interest, optimization algorithms can provide advantages that complement the power of classical numerical models. In the spirit of Maxwell, who eloquently spoke for a balance between abstract mathematical symbolism and observable attributes of concrete objects, this paper is an examination of the central ideas of the two approaches, and a reflection on how Maxwell&apos;s integral visualization may be practically put to use in a world of digital computers.

    A prominent specialist on the Russian economy provides a framing comment on two preceding papers entitled &apos;Russia&apos;s Energy Policy&apos; (by Vladimir Milov, Leonard Coburn, and Igor Danchenko) and &apos;Russia&apos;s Energy Policy: A Divergent View&apos; (by Matthew J. Sagers). The author argues that Russia&apos;s current energy policy should be viewed as an outcome of competition between three overlapping programs. In this context, he identifies three policy models - the old Soviet, the liberal or oligarchic, and the most recent state capitalist. The latter is currently supported by President Putin, who prioritizes diversification of the country&apos;s economy at the expense of diminished investments in the oil and gas sector.

    We dicusss the meaning and prove the accordance of general relativity, wave mechanics, and the quantization of Einstein&apos;s gravitation equations themselves. Firstly, we have the problem of the influence of gravitational fields on the de Broglie waves, which influence is in accordance with Einstein&apos;s weak principle of equivalence and the limitation of measurements given by Heisenberg&apos;s uncertainty relations. Secondly, the quantization of the gravitational fields is a &apos;&apos;quantization of geometry.&apos;&apos; However, classical and quantum gravitation have the same physical meaning according to limitations of measurements given by Einstein&apos;s strong principle of equivalence and the Heisenberg uncertainties for the mechanics of test bodies.

    The REIMEP-22 inter-laboratory comparison aimed at determining the production date of a uranium certified test sample (i.e. the last chemical separation date of the material). Participants in REIMEP-22 on &apos;&apos;U Age Dating - Determination of the production date of a uranium certified test sample&apos;&apos; received one low-enriched 20 mg uranium sample for mass spectrometry measurements and/or one 50 mg uranium sample for a-spectrometry measurements, with an undisclosed value for the production date. They were asked to report the isotope amount ratios n({sup 230}Th)/n({sup 234}U) for the 20 mg uranium sample and/or the activity ratios A({sup 230}Th)/A({sup 234}U) for the 50 mg uranium sample in addition to the calculated production date of the certified test samples with its uncertainty. Reporting of the {sup 231}Pa/{sup 235}U ratio and the respective calculated production date was optional. Eleven laboratories reported results in REIMEP-22. Two of them reported results for both the 20 mg and 50 mg uranium certified test samples. The measurement capability of the participants was assessed against the independent REIMEP-22 reference value by means of z- and zeta-scores in compliance with ISO 13528:2005. Furthermore a performance assessment criterion for acceptable uncertainty was applied to evaluate the participants&apos; results. In general, the REIMEP-22 participants&apos; results were satisfactory. This confirms the analytical capabilities of laboratories to determine accurately the age of uranium materials with low amount of ingrown thorium (young certified test sample). The Joint Research Centre of the European Commission (EC-JRC) organised REIMEP-22 in parallel to the preparation and certification of a uranium reference material certified for the production date (IRMM-1000a and IRMM-1000b).

    The aim of this work was to experimentally determine the &apos;dynamic filter factor&apos; in symmetrical fields for energies of 6 MV and 15 MV and to compare these results with values obtained by treatment planning system (Cad Plan) under the same conditions. So that, is possible to attribute, for treatment calculation with fields of irradiation that use dynamic filter, the same depth dose percentage used for opened field, without filter. In this way, is validated the system of planning CAD PLAN calculation used in this Institution.

  8. Deep groundwater flow systems and their characterization in single-well settings by &apos;'push-pull'&apos; tracer tests

    2014-11-21

    This thesis demonstrates the growing importance of deep groundwater research and the increasing demand for the development of suitable single-well test methods. At the forefront of the research on groundwater in the deep underground, radioactive waste disposal in deep geological repositories, CO{sub 2} storage, geothermal energy supply, and aquifer storage and recovery systems (ASR) are on the agenda. The developments of suitable methods for investigating these resources are a main target. Currently available methods show considerable limitations. Accordingly, comprehensive methods for the hydraulic and hydrochemical characterization of deeper aquifers with single-well access are needed. Therefore, the goal of this PhD thesis was to identify, test, and enhance potentially suitable single-well methods for characterization of groundwater flow and solute transport in such settings. For this, several Single-Well Injection-Withdrawal (&apos;'push-pull'&apos;) tracer tests were applied at the Hamasato field site (Horonobe, Japan) in a ∝100 m deep groundwater monitoring well. Aim was to characterize the impact of a dynamic saltwater-freshwater interface on a coastal aquifer. Based on the experiences of the first methodological test, a second field campaign was conducted. This campaign focused on a systematic evaluation of the push-pull tracer test method for the first time at all. The experiments focused on the investigation of the so-called &apos;'chaser'&apos; and its impact on the test results. The chaser is a specific part of many push-pull tracer tests setups. From these experiments, a specific test design for the investigation of the saltwater-freshwater interface in a single-well setting was developed. The application of this design on questions regarding different fluids within the same system, e.g. different mineralized fluids (saltwater-freshwater-interface, ASR) or temperatures (geothermal research), are promising future approaches for

    Full Text Available Biomarkers are the only feasible way to detect and monitor presymptomatic Alzheimer's disease (AD. No single biomarker can predict future cognitive decline with an acceptable level of accuracy. In addition to designing powerful multimodal diagnostic platforms, a careful investigation of the major sources of disease heterogeneity and their influence on biomarker changes is needed. Here we investigated the accuracy of a novel multimodal biomarker classifier for differentiating cognitively normal (NC, mild cognitive impairment (MCI and AD subjects with and without stratification by ApoE4 genotype. 111 NC, 182 MCI and 95 AD ADNI participants provided both structural MRI and CSF data at baseline. We used an automated machine-learning classifier to test the ability of hippocampal volume and CSF Aβ, t-tau and p-tau levels, both separately and in combination, to differentiate NC, MCI and AD subjects, and predict conversion. We hypothesized that the combined hippocampal/CSF biomarker classifier model would achieve the highest accuracy in differentiating between the three diagnostic groups and that ApoE4 genotype will affect both diagnostic accuracy and biomarker selection. The combined hippocampal/CSF classifier performed better than hippocampus-only classifier in differentiating NC from MCI and NC from AD. It also outperformed the CSF-only classifier in differentiating NC vs. AD. Our amyloid marker played a role in discriminating NC from MCI or AD but not for MCI vs. AD. Neurodegenerative markers contributed to accurate discrimination of AD from NC and MCI but not NC from MCI. Classifiers predicting MCI conversion performed well only after ApoE4 stratification. Hippocampal volume and sex achieved AUC = 0.68 for predicting conversion in the ApoE4-positive MCI, while CSF p-tau, education and sex achieved AUC = 0.89 for predicting conversion in ApoE4-negative MCI. These observations support the proposed biomarker trajectory in AD, which postulates

    Background. This paper reports three children with short stature: developmental coxa vara unilateral in the first case and bilateral in the other two; somewhat squared and &apos;'ovoid'&apos; vertebral bodies in the first patient, and normal to slightly tall vertebral bodies in the third; metaphyseal changes in some long tubular bones including bone fragments similar to the corner fractures seen in child abuse in all three patients. Materials and methods. The first and second patients were sisters; their mother, also quite short, had surgical procedures in early life for bilateral &apos;&apos;coxa vara&apos;&apos;; their brother, also of short stature, had bilateral coxa valga with otherwise normal femoral heads and necks, and mild metaphyseal changes associated with two minute &apos;&apos;corner fractures&apos;&apos; in the proximal metaphysis of the left tibia. Results. A review of reported cases of developmental coxa vara associated with spondylometaphyseal dysplasia revealed that simulated corner fractures were present in most instances. (orig.)

    2010-08-01

    Full Text Available BACKGROUND: Obesity has a central role in the metabolic syndrome, which raises the risk for atherosclerotic cardiovascular disease (ASVCD. Apo B-48 and Apo B-100 are the necessary structural proteins required for the assembly and secretion of chylomicron and VLDL which have role in atherogenesis. The key initiating process in atherogenesis is the subendothelial retention of apolipoprotein B-containing lipoproteins. Oxidation of LDL is a hallmark of atherosclerosis development. The aim of this study was to asses the association between Apo B-48 and Apo B-100 with Oxidized-LDL as marker of atherosclerosis risk in central obesity. We hope that the result of this study can help to make a new strategy for the prevention and treatment of vascular disease. RESULTS: There were 68 patients aged 39.6±7.3 years, Apo B-48 concentration was 7.47±5.36 μg/mL, Apo B-100 was 117.26±25.74 mg/dL, and ox-LDL was 137.05±18.88 U/L. This study showed a significant correlation between Apo B-100 and ox-LDL (r=0.608, p<0.05 and correlation between Apo B-48 and ox-LDL (r= 0.171, p<0.05. The levels of Apo B-100 were significantly different between obese with Mets and obese without Mets individuals (p<0.05. CONCLUSIONS: This study suggested that Apo B-100 concentration increase in obese in Mets as compared with obese without Mets. Apo B-48 and Apo B-100 were correlated with Oxidized LDL, but correlation between Apo B-100 and ox-LDL more significant that Apo B-48and ox-LDL. KEYWORDS: obesity, atherogenesis, Apo B-48, Apo B-100, ox-LDL.

From the 12 orientation variants, only 3 orientations between the matrix and S-phase precipitates were taking into consideration in this study. It was found that the metastable S&apos;&apos;-phase could be explained as an orientation variant of the equilibrium S-phase (Al{sub 2}CuMg). It is worth mentioning that the third variant has not been reported in the literature using HTREM, therefore, the incorporation of this variant in the analysis provides an alternative explanation for the experimental evidence previously used as support for the S&apos;&apos;-phase.

  7. High-Fat Diet Changes Hippocampal Apolipoprotein E (ApoE in a Genotype- and Carbohydrate-Dependent Manner in Mice.

    Directory of Open Access Journals (Sweden)

    Courtney Lane-Donovan

    Full Text Available Alzheimer's disease is a currently incurable neurodegenerative disease affecting millions of individuals worldwide. Risk factors for Alzheimer's disease include genetic risk factors, such as possession of ε4 allele of apolipoprotein E (ApoE4 over the risk-neutral ApoE3 allele, and lifestyle risk factors, such as diet and exercise. The intersection of these two sources of disease risk is not well understood. We investigated the impact of diet on ApoE levels by feeding wildtype, ApoE3, and ApoE4 targeted replacement (TR mice with chow, high-fat, or ketogenic (high-fat, very-low-carbohydrate diets. We found that high-fat diet affected both plasma and hippocampal levels of ApoE in an isoform-dependent manner, with high-fat diet causing a surprising reduction of hippocampal ApoE levels in ApoE3 TR mice. Conversely, the ketogenic diet had no effect on hippocampal ApoE. Our findings suggest that the use of dietary interventions to slow the progression AD should take ApoE genotype into consideration.

    The thymus is a linphoepithelial organ located mostly in the anterior mediastinum and, for a smaller part, in the neck. The gland is particularly developed in the fetus and in children, while it shrinks in young adults following an involution process. It has been investigated the US appearance of the thymus in normal pediatric subjects to gather information for use in pediatric patients with suspected thymus conditions, using a safe, irradiation-free, technique. It has performed a US examination of the anterior mediastinum and the neck in 30 children (14 males and 16 females) ranging in age 6 months to 11 years. It was used a Sonora Logic 700 MD General Electric&apos;s unit with 7.5-13 MHz linear probes and acquired transverse and longitudinal scans on the chest wall and the neck, integrated with intercostal scans. The thymus had the same echogenicity as the liver parenchyma in 22 children (73.3%), lower echogenicity in 2 (6.6%, age range 6-12 months) and higher echogenicity with heterogenous structure in 6 children (20%, age range 8-11 years). The gland was in central and symmetric localization in 20 children (66.6%) while it exhibited a slight deviation leftwards in 7 (23.3%) nd rightwards in 3 children (10%). It was considered as normal the following values: in the right lobe 1.4 cm for the AP diameter and 2.5 cm for the longitudinal one; in the left lobe, 1.4 cm for the AP diameter and 2.9 cm for the longitudinal one. Radiological studies of the thymus are really difficult to perform because the gland is extremely variable in size, extension and page. The thymus has the same echogenicity as the liver parenchyma and lower echogenicity than the thyroid parenchyma. It has believed that US is an effective technique for studying the thymus in all its involution stages and that provides similar information to CT and MRI. Also, US does not use radiations and needs no sedation, which improves safety for young patients. [Italian] Il timo localizzato prevalentemente nel

    Gamma-ray scanning, often referred to as &apos;column scanning&apos;, is a convenient, cost effective, fast, efficient and non-invasive technique to examine internal characteristics of a certain equipment, like alcohol distillation columns, while it is in operation. Column scanning allows to engineers, to study hydraulics tray inside of distillation column in on-line condition. It provides essential data to optimize the performance of columns, extend column run times, to evaluate effects of defective track and to identify maintenance requirements. This knowledge can reduce repair times significantly. In the year 2014, the Environmental Radiological Surveillance Laboratory from Center of Radiation Protection and Hygiene, introduced this service in the &apos;Hector Molina&apos; Distillery. The diagnosis carried out allowed the detection of some anomalies in its operation. In this work the results obtained during gamma-ray scanning of the column are shown. (Author)

    The LDL receptor (LDLR) family has long been studied for its role in cholesterol transport and metabolism; however, the identification of ApoE4, an LDLR ligand, as a genetic risk factor for late-onset Alzheimer's disease has focused attention on the role this receptor family plays in the CNS. Surprisingly, it was discovered that two LDLR family members, ApoE receptor 2 (Apoer2) and VLDL receptor (Vldlr), play key roles in brain development and adult synaptic plasticity, primarily by mediating Reelin signaling. This review focuses on Apoer2 and Vldlr signaling in the CNS and its role in human disease. Copyright © 2017 by the American Society for Biochemistry and Molecular Biology, Inc.

    2004-01-01

    The aim of this work is to determine the importance of &apos;K&apos; ionizations on DNA as critical physical events initiating the biological effects of ionizing radiation, in particular in human cells. Ultra-soft X-rays are used as a probe of core ionization events. A decisive test consists in comparing the biological effects at 250 eV and 350 eV (before and after the carbon K - threshold). The results show a sharp increase of the biological efficiency for both cellular inactivation and chromosomal exchange aberration above the carbon K-threshold, correlated with the one of core events occurring in DNA atoms. The heavy ion irradiation displays again the paradoxical behaviour of cellular inactivation cross sections as a function of LET. Finally, the &apos;K&apos; event contribution to cellular inactivation of usual low LET radiation is estimated to be about 75%. (author) [fr

The refurbishment of the computer centre, run by the Swiss Post&apos;s Internet finance portal, is discussed. In particular, the important role played by the complex&apos;s state-of-the-art air-conditioning and cooling systems is looked at. Free-cooling - the use of low ambient temperatures for the direct cooling without refrigeration equipment - is discussed. The limitations posed on this refurbishment project by the fail-safe operation of the computer centre are examined. Technical details on the new cooling system are presented and redundancy aspects of the new installation are discussed.

    Children who are able to recognize others&apos; emotions are successful in a variety of socioemotional domains, yet we know little about how school-aged children&apos;s abilities develop, particularly in the family context. We hypothesized that children develop emotion recognition skill as a function of parents&apos; own emotion-related beliefs,…

    In a forcing culture of the &apos;Black Beauty&apos;- type eggplant &apos;Kurowashi&apos; (Solanum melongena var. esculentum (L.) Nees), comparisons were made in respect to growth and yield under near-ultraviolet radiation-100% absorbing vinyl film (UV100 film), and those under standard greenhouse vinyl film (standard film). Investigations were also made on the influence of the number of shoots and planting density. 1. Under UV100 film, shoot growth was the same as under standard film. The total number of flowers was somewhat increased, but the rate of harvested fruit decreased, and the yield of marketable fruit was less. On the other hand, there was little difference in the color of leaves or fruit skins; however, the green color of the shoots was lighter. 2. Under the UV100 film, when the planting system used a 180cm ridge width and a single row, the yield of marketable fruit with 2 shoots training (1,389 stocks/10a) was more than 4 shoots training (694 stocks/10a), when the numbers of shoots per unit area were the same. Moreover, with the 2 shoots training, the yield of marketable fruit for the 35cm intra-row spacing (1,587 stocks/10a) was more than the 40cm intra-row spacing (1,389 stocks/10a)

    While plagiarism by college students is a serious problem that must be addressed, students generally overestimate the frequency of plagiarism at their schools and blame students they do not know for the majority of incidents. This study looked at students&apos; estimations of the frequency of plagiarism at a large urban college and explored how…

    The &apos;Elguea&apos; spa, located in the north coast of the county of Villa Clara, Cuba, is considered one of those more important spas of Latin America. The waters of this spa are rich in salts of chlorine, sodium, bromine, sulfides and its contain radon. As a result of measurements of environmental gamma dose rates carried out in the area of the spa, its were considered levels of dose between 0.13 and 2.3 mSv. The obtained results motivated that it was carried out a characterization, from the radiological point of view, of the spa. This characterization is of supreme importance to be able to evaluate the impact that it has and the discharges of its waters on the environment, as well as, those dose that the population potentially affected can receive by these discharges. With this end its were carried out quantitative determinations of those existent natural more significant radionuclides in different environmental objects coming from the area of the spa and its surroundings, as well as one characterization gamma &apos;in situ&apos; of the same one. The obtained results are present in this work. (Author)
