    In this work various treatments for protecting reinforcing steels against corrosion induced by chlorides have been evaluated. Additives to mortars and surface treatments given to reinforcing steels were evaluated as corrosion protection measures. In the preliminary tests the corrosion resistance of a CA 50 steel treated by immersion in nearly 50 different solutions, was determined. The solutions were prepared with tannins (from various sources) and/or benzotriazole, and during immersion, a surface film formed on the steel. The corrosion resistance of the coated steels was evaluated in a saturated Ca(OH){sub 2} solution with 5% (wt) NaCl. Preliminary tests were also carried out with mortars reinforced with uncoated steel to which tannin or lignin was added. Two organic coatings, a monocomponent and a bicomponent type, formulated specially for this investigation, with both tannin and benzotriazole, were also tested in the preliminary tests to select the coating with better corrosion protection property. The bicomponent type (epoxy coating) showed better performance than the monocomponent type coating, and the former was therefore chosen to investigate the corrosion performance on CA 50 steel inside mortar specimens. From the preliminary tests, two solutions with tannin from two sources, Black Wattle (Acacia mearnsii) and Brazilian tea (Ilex paraguariensis St. Hill), to which benzotriazole and phosphoric acid were added, were chosen. Mortar specimens reinforced with CA50 steel treated by immersion in these two solutions were prepared. Also, epoxy coated CA50 steel was tested as reinforcement inside mortar specimens. Mortars reinforced with uncoated CA50 steel were also prepared and corrosion tested for comparison. The effect of tannin and lignin as separate additives to the mortar on the corrosion resistance of uncoated steel was also studied. The reinforced mortar specimens were tested with various cycles of immersion for 2 days in 3.5% (wt) NaCl followed by with air drying for 5 days. The corrosion tests used in this investigation were gravimetric and electrochemical tests. The results showed satisfactory corrosion performance for all kinds of protection measures. However, the performance depended on the type of protection used. The best performance was obtained with tannin containing epoxy coated steel, followed by the steel treated by immersion in tannin containing solutions and finally by the addition of tannin (Black Wattle) or lignin to the mortar. All the protection measures evaluated in this study are economically viable and environmentally friendly and can therefore be considered for protecting reinforcement steels against corrosion.

    Full Text Available This article briefly reviews the recent history of the Spanish Armed Forces, stressing the importance of the military institution and its role in contemporary Spanish history. Following Franco’s death there was an attempt to bring the command of the Armed Forces under democratic control within the constitution, a process in which General Gutiérrez Mellado played a crucial role. Since 1981, two important measures have been taken in the military sphere: “case 2/81”, prosecuting the perpetrators of the attempted coup in 1981, and Spain’s application to join the Atlantic Alliance (NATO, a very important step in shaping the country’s future and driving the modernisation of the Spanish Armed Forces, putting them on an equal footing with their peers elsewhere in the Western world. After the socialist victory in 1982, the PSOE government changed direction, skilfully transforming its initial anti-Americanism, obtaining Spain’s membership of NATO following the 1986 referendum, and profoundly changing the Armed Forces, thus eliminating military tensions. The last stage of the modernisation process was led by Aznar’s government, with the professionalisation of the Armed Forces and the integration of Spain in NATO’s military structure.El artículo realiza un breve repaso por la historia de las Fuerzas Armadas españolas destacando la importancia de la institución militar y su papel en la Historia contemporánea española. Desde de la muerte de Franco se intenta por encauzar a los mandos de las Fuerzas Armadas en la senda democrática y constitucional, siendo entonces crucial el papel del General Gutiérrez Mellado. A partir de 1981, se toman dos importantes medidas en la esfera militar: la llamada causa 2/81, para el enjuiciamiento de los responsables de la intentona golpista y la solicitud de ingreso de España en la Alianza Atlántica, paso muy importante que determinará el futuro del país y permitió la modernización de las Fuerzas

    Full Text Available Within an extensive research program developed at the University of Lieja in the components of the reinforced masonry, blocks, mortar and reinforcements, this article deals with the part which refers to building masonry works with special reinforcements "Murfor RE". This revolutionary system of prefabricated reinforcements of tridimensional character formed by two longitudinal wires bound together through stirrups at regular distances, has the advantage of allowing the block masonry to be reinforced in two directions, vertical and horizontal, during the simple process of execution of bricklaying in courses. According to this research, the obtained compound result, compared with the solutions already known of block masonries made of reinforced hollow concrete, surpasses them in properties. It is competitive with the reinforced concrete in many cases and can be also used in masonries made of ceramic blocks with wide perforations.

    2012-10-01

    Full Text Available Abstract Background Sharing of data about variation and the associated phenotypes is a critical need, yet variant information can be arbitrarily complex, making a single standard vocabulary elusive and re-formatting difficult. Complex standards have proven too time-consuming to implement. Results The GEN2PHEN project addressed these difficulties by developing a comprehensive data model for capturing biomedical observations, Observ-OM, and building the VarioML format around it. VarioML pairs a simplified open specification for describing variants, with a toolkit for adapting the specification into one's own research workflow. Straightforward variant data can be captured, federated, and exchanged with no overhead; more complex data can be described, without loss of compatibility. The open specification enables push-button submission to gene variant databases (LSDBs e.g., the Leiden Open Variation Database, using the Cafe Variome data publishing service, while VarioML bidirectionally transforms data between XML and web-application code formats, opening up new possibilities for open source web applications building on shared data. A Java implementation toolkit makes VarioML easily integrated into biomedical applications. VarioML is designed primarily for LSDB data submission and transfer scenarios, but can also be used as a standard variation data format for JSON and XML document databases and user interface components. Conclusions VarioML is a set of tools and practices improving the availability, quality, and comprehensibility of human variation information. It enables researchers, diagnostic laboratories, and clinics to share that information with ease, clarity, and without ambiguity.

    Endoscopic biopsy for intraventricular tumors in pediatric patients with small ventricles is a challenging procedure because of the risk of morbidity during the intraventricular approach. We describe the use of the VarioGuide system for intraventricular endoscopic biopsy in 9 consecutive pediatric patients with intraventricular lesions and small ventricular size. All patients had lesions in the anterior part of the third ventricle with a median frontal and occipital horn ratio of 0.33. Patients presented with growth failure (n = 4), visual disturbances (n = 4), and seizures (n = 1). The VarioGuide system consists of an ergonomic arm with 3 joints for gross adjustment. The 3 rotational joints on the distal side of the system are adjusted according to the angles of the planned trajectory. The endoscope is adjusted to the distal side of the VarioGuide and inserted through the ring, previously set for the diameter of the endoscope and for the planned trajectory. The accuracy of the trajectory and correct ventricular cannulation are confirmed under endoscopic guidance. The biopsy is carried out according to the standard technique. In all cases, the biopsy sample provided the definitive diagnosis. Diagnoses included germinomas in 4 patients, hamartoma in 1 patient, hypothalamic astrocytoma in 2 patients, and craniopharyngioma in 2 patients. The use of the VarioGuide system for intraventricular endoscopic biopsy is highly recommended for pediatric patients with small ventricle size. This technique may help minimize the risk of unnecessary brain damage during the entrance to small ventricles.

Si cerca quindi di dimostrare: a il legame fra tale “varietà lirica” e il «vario stile» del sonetto proemiale del Canzoniere; b l’esistenza di un paradigma medievale della lirica come ‘poesia metricamente e stilisticamente varia’ da accostare a quello classico di ‘poesia cantata al suono della lira’ e a quello moderno di ‘poesia come espressione dell’interiorità’. The paper analyses the circulation of the definition of lyric poetry given by Isidore of Seville in his Etymologiae, which was based on formal variety. The author tries to prove: a the link between this “lyrical variety” and the «vario stile» in the first sonnet of Petrarch’s Rerum vulgarium fragmenta; b the presence of a medieval idea of lyric as ‘poetry caracterized by metrical and stylistic variety’ that we propose to add to the classical (‘poetry accompanied by music’ and modern idea (‘genre which expresses personal feelings’.

Playing with stereotypes, the photography actively contributes to establishing argumentative strategies meant to make the reader-viewer adhere to the message, all while affirming itself as an autonomous aesthetic experience.España de sol a sol (2001 de Alfonso Armada proporciona una muestra de la evolución del género del «libro de viajes» en la España contemporánea.

La poética del viaje que propone el relato difiere profundamente de la de los escritores viajeros del «realismo social», en la España de los años sesenta, anteponiendo la interpretación a la información, la imagen poética a la función referencial del lenguaje, cultivando la polisemia, una intertextualidad masiva y una reflexión metatextual. Distintos son también los vínculos que se establecen entre texto e imagen, de complementariedad más que de redundancia.

    1988-03-01

    Recently, researchers have placed great hopes on artificial neural networks to perform such ''natural'' tasks as speech recognition. This was indeed one motivation for us to start research in this area many years ago at Helsinki University of Technology. This article describes the result of that research - a complete ''neural'' speech recognition system, which recognizes phonetic units, called phonemes, from a continuous speech signal. Although motivated by neural network principles, the choices in design must be regarded as a compromise of many technical aspects of those principles. As our system is a genuine ''phonetic typewriter'' intended to transcribe orthographically edited text from an unlimited vocabulary, it cannot be directed compared with any more conventional, word-based system that applies classical concepts such as dynamic time warping and hidden Markov models.

Isso leva a um trajeto expositivo que considera os contextos estratégicos e domésticos à luz das determinações constitucionais e dos termos de acordos internacionais que constrangem as alternativas brasileiras de uso de força. Conclui-se que o Brasil tem apenas três tarefas concretas para suas Forças Armadas: a defesa do território, a participação em ações internacionais e a garantia da lei e da ordem, circunscrito em todos os casos ao uso de armamentos convencionais. Responde-se à pergunta de partida afirmando que se tem Forças Armadas para sustentar a capacidade de realizar estas tarefas ao longo do tempo e em qualquer momento. Como e quanto se sustenta tal capacidade são os critérios essenciais para a formulação, condução e avaliação da política de defesa do Brasil.This article offers a structural answer to the question: what are Brazil's armed forces for? This leads to the appreciation of Brazil's strategic and domestic contexts of the use of armed force. It considers the constitutional imperatives and the terms of international agreements that curtail Brazilian alternatives. It argues that Brazil has only three concrete tasks for its armed forces: the defense of its territory, the participation in international missions, and the guarantee of law and order, being constrained further to the use of conventional weapons. It answers the question it began with as follows: Brazil's armed forces exist to sustain the capacity of carrying out these tasks over time and at any time. It concludes that how and how well a Brazilian defense policy sustains this capacity are the paramount criteria for its conception, management and evaluation.

    Full Text Available At the design of a project for remodeling the old building and constructing new ones at the dock of the National Navy of Argentina, several additions were introduced to provide the civil staff with necessary installations. In view of the fact that the available space was quite restricted, the work was carried out in the following way: demolition of old buildings, construction of new ones to meet the present requirements and increase of the number of storeys in the already existing buildings. For the enlargement of the dining room, wardrobes and other service sections of the civil staff, one of the old buildings has been used, where the roof was replaced by a prefabricated hollow floor of reinforced concrete. The thus formed upped floor was covered with self-supporting, also prefabricated terracotta vaults, the cores of which are of reinforced concrete. The Labour Relations Office occupies a circular shaped area with walls of concrete blocks that support the terracotta dome. Thanks to the use of rationalized construction procedures and to the use of important auxiliary means, the work was carried out in a precise, rapid and economical manner, by mixing members that were prefabricated in series on the site with the traditional construction system.La creación de un plan de construcciones nuevas y remodelación de las antiguas en el dique de la Armada Nacional, se aprovechó para realizar toda una serie de instalaciones necesarias de servicio para el personal civil de dicha organización.

    Full Text Available En el primer cuarto del siglo XVIII se crea el Arsenal de la Carraca, considerado como el principal astillero de la Armada Española. La masiva llegada de operarios civiles y militares ante la oferta de trabajo, motivó un problema asistencial sanitario, que se solventó a través de una improvisada enfermería de madera y otros hospitales provisionales instalados en la Isla de León. Finalmente, en 1756 se pudo fundar el «Real Hospital del Arsenal de la Carraca». Este nosocomio tuvo un papel crucial en la epidemia de fiebre amarilla de 1800 y en los dos primeros años de la Guerra de la Independencia, hasta que en agosto de 1810 tuvo que ser desalojado ante el riesgo de bombardeo de las baterías francesas apostadas en Puerto Real, siendo reconvertido en un «hospital de sangre». No obstante, en la segunda grave epidemia de fiebre amarilla de 1819, el hospital tuvo que ser reactivado como en sus orígenes. Debido a la restructuración hospitalaria en la bahía de Cádiz, la Armada procedió a su extinción en el año 1821, tal y como muestra el documento que lo acredita encontrado en el Archivo General de Marina «Álvaro de Bazán». En este trabajo se exponen las vicisitudes sanitarias y humanas de este Real Hospital a lo largo de 65 años claves en la historia de España.

    Full Text Available O texto apresenta resultados de uma pesquisa sobre as perceções de um grupo de trabalhadores que integram um segmento periférico das Forças Armadas portuguesas, contratados a termo e em situação de mobilidade geográfica mensal. Procurou conhecer os impactos destes tipos de flexibilidade nas forças armadas sobre as suas expetativas e estratégias profissionais e pessoais. Foram utilizados inquéritos por questionário e entrevistas semiestruturadas. Verificou-se a existência de precaridade de emprego e de trabalho, que são fontes de insatisfação; sentimento de segmentação laboral relativamente ao núcleo-duro; dificuldades de conciliação e de acesso a formação. Concluiu-se que os desafios para a organização militar são bastantes, com uma força de trabalho que tende a apresentar-se desmoralizada pela precariedade, pela sensação de rotina, fadiga e impossibilidade de progressão. Para os indivíduos, a consciência de "trabalhador nómada" começa a pesar, com as deslocações constantes, com a aproximação do fim do contrato e com a necessidade de preparação para a reintegração no mercado de trabalho. A precariedade é hoje experienciada num dos setores que ainda há pouco se considerava dos mais estruturados e que garantia permanência e estabilidade de carreira, o militar, e que hoje é também já um local de "passagem" dos seus "profissionais".

    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 ''push'' or as a ''pull'' change methodology. ''Push'' is the operational improvement role of TQM; ''pull'' 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 ''push'' and ''pull'' 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 ''push-pull'' 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 ''push''-based TQM activity that is driven by strategic or ''pull'' based TQM planning and activity. (author)

    Full Text Available The «Loreto Massacre» and the subsequent process of popular justice to which its author was brought illustrate how the arming of the inhabitants of this district of La Paz combated not only the partisan abuse of power, but also the threat posed to Bolivia’s constitutional legal framework by military revolutions. In a process of «political fusion», the «people on the streets» and the people as represented by the government took armed and associative action against an attempted military coup. This process also implied the employment of political action as an instrument against the devaluation of labour and artisan production.

    Los casos de la Matanza del Loreto y del posterior ajusticiamiento popular de su responsable ilustran cómo la conversión del vecindario paceño en el pueblo en armas combatió tanto el abuso partidista del poder, como la ruptura de la legalidad constitucional ejercida por las revoluciones militaristas. El pueblo en la calle y el pueblo representado en una junta de gobierno contribuyeron a la institucionalización del Estado —expresada en la política de fusión— al actuar armada y asociativamente contra el militarismo golpista, tomándose también la acción política en un medio contra la devaluación laboral y de estatus de los artesanos.

    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 ''HEDRad'' (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).

    Full Text Available En el presente artículo se analizan las relaciones entre cambios tecnológicos y proyectos económicos que experimentaron los militares chilenos entre 1860 y 1930, y que conformaron algunas corrientes a favor de la industria, del nacionalismo económico y de la intervención del Estado en sectores que se consideraron como estratégicos, todo lo cual adquirió notoriedad en la década de 1920. Sin embargo, dichas corrientes no lograron consenso y fueron combatidas por los empresarios y la tecnocracia. Se explora una explicación que considera los límites impuestos a los militares por los civiles en el control del Estado y de la economía, la incompleta modernización tecnológica, las concepciones contrapuestas entre la Armada y el Ejército sobre sus proveedores de armas, además de que los posibles escenarios de guerra de Chile no serían de gran escala. Todo ello descartó una posible alianza de intereses militares, empresariales y tecnocráticos para conformar un complejo militar industrial de mayor alcance.This article analyses the relationship between technological changes and economic projects experienced by Chilean military institutions between 1860 and 1930. These changes were part of industrializing streams that emerged as a result of economic nationalism and State interventions in strategic áreas since the 1920s. However, these measures did not have an institutional consensus and were opposed by businessmen and technocrats. The article considers different aspects including the limits imposed to military institutions by civilians in terms of State control and economic management as well as the incomplete technological modernization and different views of the Army and Navy over weapon providers and the kind of potential war scenarios. All of these made the alliance between military, businessmen and technocrat interests to créate a military industrial facility impossible.

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

    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.

  15. Neutrino-gaseous &apos;'pancakes'&apos; and the problem of hidden mass

    1983-08-01

    Taking into account peculiar velocities of neutrinos the gaseous component is shown to dominate in the central part of a cosmological &apos;'pancake'&apos; (rhosub(p) > rhosub(..nu..)), while on the average anti rhosub(b) << anti rhosub(..nu..). Therefore fragmentation of a gaseous &apos;'pancake'&apos; and later clustering of the fragments into galaxies and groups of galaxies are determined by velocity distribution and gravity of the gaseous component. The hidden mass is formed by capture of neutrinos by clustering clouds. Formation of the cluster of galaxies is connected with perturbations embracing all the neutrino-gaseous &apos;'pancake'&apos;, initial ratio of neutrino-to-gaseous densities being reestablished. It is shown that the first &apos;'pancakes'&apos; were formed at the red shifts z=5-8.

    Quasar feedback in the form of powerful outflows is invoked as a key mechanism to quench star formation in galaxies, preventing massive galaxies to overgrow and producing the red colors of ellipticals. On the other hand, some models are also requiring &apos;'positive'&apos; active galactic nucleus feedback, inducing star formation in the host galaxy through enhanced gas pressure in the interstellar medium. However, finding observational evidence of the effects of both types of feedback is still one of the main challenges of extragalactic astronomy, as few observations of energetic and extended radiatively driven winds are available. Here we present SINFONI near infrared integral field spectroscopy of XID2028, an obscured, radio-quiet z = 1.59 QSO detected in the XMM-COSMOS survey, in which we clearly resolve a fast (1500 km s{sup –1}) and extended (up to 13 kpc from the black hole) outflow in the [O III] lines emitting gas, whose large velocity and outflow rate are not sustainable by star formation only. The narrow component of Hα emission and the rest frame U-band flux from Hubble Space Telescope/Advanced Camera for Surveys imaging enable to map the current star formation in the host galaxy: both tracers independently show that the outflow position lies in the center of an empty cavity surrounded by star forming regions on its edge. The outflow is therefore removing the gas from the host galaxy (&apos;&apos;negative feedback&apos;&apos;), but also triggering star formation by outflow induced pressure at the edges (&apos;&apos;positive feedback&apos;&apos;). XID2028 represents the first example of a host galaxy showing both types of feedback simultaneously at work.

    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.

  6. ApoE polymorphisms in narcolepsy

    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.

    It is recommended that the degree of characteristic variation in the geological parameters by area be accounted for using the &apos;'trend'&apos; characteristic when evaluating the geological inhomogeneity of formations; this characteristic denotes any systematic variations which are noted in the diagram of the target under study. A method for solving these problems is proposed. A problem is solved using a sample study of the ruggedness factor of several beds in the 16th formation and the series of the 15th formation in the Starii field and the Bukhti Ilch field in Bibi-Eibat. The &apos;&apos;regression analysis&apos;&apos; program was used in drafting these models; this program was developed at the computer center of the Academy of Sciences of the Estonian SSR. A multiple correlation coefficient for square-law models was used to evaluate the &apos;'trend'&apos;.

    We discuss a novel approach to &apos;'weighing'&apos; the Milky Way (MW) dark matter halo, one that combines the latest samples of halo stars selected from the Sloan Digital Sky Survey (SDSS) with state of the art numerical simulations of MW analogs. The fully cosmological runs employed in the present study include &apos;'Eris'&apos;, one of the highest resolution hydrodynamical simulations of the formation of a M{sub vir} = 8 Multiplication-Sign 10{sup 11} M{sub Sun} late-type spiral, and the dark-matter-only M{sub vir} = 1.7 Multiplication-Sign 10{sup 12} M{sub Sun} &apos;&apos;Via Lactea II&apos;&apos; (VLII) simulation. Eris provides an excellent laboratory for creating mock SDSS samples of tracer halo stars, and we successfully compare their density, velocity anisotropy, and radial velocity dispersion profiles with the observational data. Most mock SDSS realizations show the same &apos;&apos;cold veil&apos;&apos; recently observed in the distant stellar halo of the MW, with tracers as cold as {sigma}{sub los} Almost-Equal-To 50 km s{sup -1} between 100 and 150 kpc. Controlled experiments based on the integration of the spherical Jeans equation as well as a particle tagging technique applied to VLII show that a &apos;'heavy'&apos; M{sub vir} Almost-Equal-To 2 Multiplication-Sign 10{sup 12} M{sub Sun} realistic host produces a poor fit to the kinematic SDSS data. We argue that these results offer added evidence for a &apos;'light'&apos;, centrally concentrated MW halo.

The first residential buildings of this type were built in 1998 and the first tertiary buildings in 2000. Such a passive house must fulfill 5 efficiency criteria: annual space heating needs {<=} 15 kWh/m{sup 2}, U{sub v} envelope coefficient lower than 0.15 W/(m{sup 2}.K), U{sub v} of openings lower than 0.8 W/(m{sup 2}.K), airtightness {<=} 0.6 volume/hour, and total energy needs (space heating, hot water, ventilation, lighting and domestic uses) measured at the meter lower than 42 kWh/m{sup 2}.year. This article makes a status of the effective efficiency of existing passive buildings both in the residential and tertiary sectors and presents some possible ways of improvement. (J.S.)

    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

Su conservación y calidad están estrechamente vinculadas prácticamente a todas las actividades económicas y sociales en forma ineludible, así como a la salud de su población. A la Península de Osa se le reconoce como la zona biológica más rica de Mesoamérica.Alberga una diversidad del hábitat y riqueza biológica raramente encontrada en un área pequeña. Este exótico territorio no está exento de amenazas debido a la fragmentación y destrucción del hábitat, deforestación por la explotación de la madera y mal planeamiento en el uso de la tierra, extracción ilegal de recursos, entre ellos el oro y el crecimiento de la población en sus alrededores.El presente diagnóstico tuvo como objetivo definir la situación actual y los posibles riesgos de contaminación del recurso hídrico evaluada en varios ríos de la zona de Osa. Se muestrearon varios cuerpos de agua en la zona de Piedras Blancas que se encuentra cerca de Chacarita, así como Rincón, Puerto Jiménez y la Bahía Drake, estas últimas pertenecientes a la Península de Osa. La valoración de la calidad del agua se hizo utilizando el Índice de Clasificación Holandés.A pesar de las características de la zona, esta ya presenta una contaminación incipiente, dependiendo del sitio y el mes del muestreo. La contaminación en los ríos depende de la densidad poblacional; sin embargo, los alcances de la contaminación en cada zona dependerán del tipo de suelo, del desarrollo urbanístico y la cobertura boscosa. Típico ejemplo de esta variabilidad son los poblados de Puerto Jiménez, el de Piedras Blancas y el de la Bahía de Drake.

    Full Text Available O presente artigo tem como objetivo refletir a tensa conjuntura eleitoral de 1955, no interior das Forças Armadas através dos documentos do Serviço Secreto da Delegacia de Ordem Política e Social de São Paulo (DOPS-SP e do Arquivo pessoal do deputado Augusto do Amaral Peixoto localizado no CPDOC.A vigilância sobre as facções militares neste período (1955-1956 revelava a fragilidade da distensão política impetrada pela constituição de 1946, onde o debate que ocorria na sociedade civil sobre as liberdades democráticas, assim como as reações ao cerceamento à liberdade de organização e expressão, configuravam um quadro institucional que, na visão dos militares, era caótico. Nesta perspectiva, o Serviço Secreto acompanhava de perto esta polêmica em torno da intervenção militar ou da legalidade constitucional defendida por estes grupos militares, aglutinados com os segmentos que detém o poder político e econômico e que vêem o permanente modelo de desenvolvimento do país correr riscos se, se ampliam os espaços rumo a uma democratização efetiva, mesmo a de teor liberal.

    Full Text Available La ESMA (Escuela de Mecánica de la Armada fue uno de los centros clandestinos de tortura y desaparición más activos de la última dictadura militar argentina (1976-1983: se estima que unos 5.000 desaparecidos fueron detenidos allí. A partir de la década de 1990, la ESMA se transformó en un lugar "emblemático" del recuerdo y su imagen suele ser presentada como condensación de todas las atrocidades del terrorismo de Estado. Este trabajo se propone interrogar esta centralidad de la ESMA y reconstruir el proceso de su "emblematización". El artículo analiza las representaciones de la ESMA en la prensa argentina durante los primeros meses de la apertura democrática (entre enero y mayo de 1984. Estas representaciones, conocidas como "show del horror" por su lenguaje macabro y sensacionalista, ofrecen pistas claras para emprender una reflexión sobre el primer proceso de calificación operado sobre ese lugar antes del advenimiento de los principales relatos "fundadores" de la transición democrática: el informe de la comisión de la CONADEP y el juicio a los ex comandantes.

    In the Spring of 2001, the National Research Council published &apos;&apos;Disposition of High-Level Waste and Spent Nuclear Fuel: The Continuing Societal and Technical Challenges.&apos;&apos; (1) While finding the technical case for deep geologic disposal of high-level waste and spent fuel robust, the report focused new attention on societal issues and decision-making. The report appeared against a backdrop of heightened controversy about the development of a geologic repository at Yucca Mountain, Nevada. This paper identifies three principal reasons for the National Research Council committee&apos;s finding that &apos;&apos;Difficulties in achieving public support have been seriously underestimated in the past, and opportunities to gain public trust have been missed.&apos;&apos;

    Full Text Available En el presente artículo se realiza una comparación estadística de la definición emitida por varios países sobre el concepto de Uso Racional de la Energía – URE -, usando análisis textual como método de descomposición semántica de los conceptos. Se calculan los coeficientes de correlación de Pearson y se construyen los círculos de correlación aplicando análisis de componentes principales. Como resultado se encuentran amplias diferencias entre las definiciones de los países latinos y la Unión Europea; la definición declarada por Colombia solo es similar a la de México. Se concluye que una de las razones por la cuales el Protocolo de Kioto no ha sido efectivo, es que existen definiciones divergentes del concepto de URE, lo cual modifica el horizonte de planeación de cada país. Acciones conjuntas como las de la Comunidad Europea dejan entrever la eficacia de las estrategias cuando existe unidad desde la concepción hasta la ejecución.

Este operador trabaja para una empresa fabricante de componentes de automóviles, gestionando y realizando las operaciones de entrega a clientes y recogida de materia prima. En este modelo se incluyen varios niveles de decisión fuertemente interaccionados entre sí que tienen como fin último la minimización del coste de estas operaciones (entrega de pedidos a clientes y recogida de materia prima. Aunque sea un modelo aparentemente demasiado específico y para una situación muy concreta, entendemos que su análisis resulta interesante, puesto que cada vez se tiende a considerar y analizar las operaciones logísticas de forma global y no de forma individualizada. Dada la complejidad del modelo en esta primer trabajo se realiza la descripción del mismo y se propone un primer y sencillo procedimiento heurístico para su resolución. Se analizan las soluciones obtenidas con datos reales.

    Full Text Available Los altos niveles de Na+ y Cl-, presentes en el agua empleada para el riego en la empresa de cultivos varios Sierra de Cubitas, unido a los síntomas de toxicidad y poco desarrollo vegetativo del cultivo de la papa han llevado a la dirección del Ministerio de la Agricultura a plantear la necesidad de valorar si se justifica mantener los niveles de siembra previstos del citado cultivo en esta Empresa. El estudio realizado indica que si bien el efecto tóxico sobre el cultivo puede estar presente, no es el único factor que limita actualmente los rendimientos agrícolas. Los niveles de Na+ y Cl- encontrados en el agua pueden producir toxicidad sobre el cultivo de la papa; incrementándose estos con la tecnología de riego empleada, por lo que en la empresa incide decisivamente en el resultado productivo el uso y mal manejo de aguas de mala calidad. El estudio recomienda el empleo de adaptaciones al sistema de riego para disminuir los efectos negativos sobre los rendimientos.

    We report on a posterior &apos;'nutcracker'&apos; phenomenon due to an abdominal aortic aneurysm in a patient with a retro-aortic left renal vein. A 71-year-old man with a known abdominal aortic aneurysm presented in the emergency room with mild hematuria and flank pain. Computed tomography angiography revealed an aortic aneurysm, which compressed the left renal vein between the aorta and the vertebral column. Compression of the left renal vein, due to the aorta with consecutive congestion and hematuria as well as flank pain, was previously described as nutcracker phenomenon. In case of a retro-aortic left renal vein, increase of the aortic diameter can lead to compression of the renal vein and furthermore to the classical signs and symptoms of the &apos;'nutcracker'&apos; phenomenon, even though the aneurysm is not ruptured or there are no aorto-caval or aorto-left renal vein fistulas.

    The method known as &apos;&apos;zero field NMR&apos;&apos; is reviewed. The technique allows the observation of nuclear dipolar and quadrupolar interactions in powder samples, which may otherwise be possible in high field on monocristals only. The anisotropy due to the magnetic field is removed although sensitivity is preserved. This method is compared to other Nuclear Resonance spectroscopies: its originality lies in the measurement of the coherent evolution of the system in zero field after a perturbation induced by suddenly switching the magnetic field. The Fourier transform of the &apos;&apos;zero field free induction decay&apos;&apos; then gives the &apos;&apos;zero field spectrum&apos;&apos;. The ideal experiment is described with its adaptations due to experimental constraints, as realized in our laboratory at Saclay and in the laboratory of A. Pines at Berkeley. We present with our first measurements a review of most of the results published to date on spin 1/2 as well as spin 1/2 (quadrupolar) nuclei. Possible future developments of the method are also discussed.

  10. Cloning and Expression of Apolipoprotein E3 and Its Variant apoE2 and apoE4

    2006-01-01

    In order to obtain three isoforms of apolipoprotein E (apoE), the cDNA encoding apoE3 was obtained by RT-PCR from normal human liver tissue. Site-directed mutagenesis was used to obtain the cDNAs encoding apoE2 and apoE4 isoforms. The 3 cDNAs were subcloned into vector pGEM-3Z and verified by DNA sequencing. The expression recombinant which can express the target protein as a (His) 6-tagged fusion was constructed by subcloning apoE cDNA into vector pT7-PL. The purified proteins were gained by Ni-NTA column. The SDS-PAGE results revealed the 6 His fusion proteins (apoE2, apoE3 and apoE4) were correctly expressed and purified successfully.

Aunque no existen guías explícitas de manipulación de series temporales no lineales en la profusa bibliografía actual, existen diferentes enfoques que pueden ser tomados en cuenta. Para ello se estudió una base de datos mensual correspondiente a datos del Fenómeno del Niño (ENSO, entre los años 1866 y 2006. Se explica cómo debe manipularse esta base de datos que poseen características de no linealidad, la cual será usada para hacer pronósticos varios pasos en adelante. Se aplicaron dos test estándar: Información Mutua Promedio (AMI y Falsos Vecinos más Cercanos (FNN. Se obtuvo el espaciamiento óptimo de los datos, así como el número de datos hacia atrás necesarios para pronosticar valores hacia el futuro. Luego, se diseñaron varios modelos de redes neuronales artificiales (RNA, con diferentes reglas de aprendizajes, funciones de transferencia, elementos de procesamiento (o neuronas en la capa escondida, etc., que permitieron hacer pronóstico de hasta 20 pasos en adelante. Las mejores redes correspondieron a aquellas que poseían como regla de aprendizaje la Regla Delta y la Regla Extendida, con función de transferencia sigmoide y tangente hiperbólica. El tipo de RNA usada fue una de multicapas alimentada hacia adelante y entrenada mediante la técnica de propagación hacia atrás. Se probaron redes con una, dos capas ocultas y sin ninguna capa. El mejor modelo que se obtuvo resultó ser uno consistente de una capa oculta.We indicate how to handle a large database consisting of nonlinear time series, applying different nonlinear modelling techniques to this kind of times series. Nowadays in the current references there is no explicit guide of how to manipulate data from nonlinear time series; however, there are approaches that can be taken account. To this end

Las inyecciones armadas es una técnica de tratamiento de mejora del terreno, mediante la ejecución de inyecciones controladas utilizando la técnica de tubos manguitos, (técnica conocida y aplicada en el campo de la ingeniería, pero con muy poca difusión en la edificación, si bien, es una técnica de gran aplicación en este ámbito, no solamente en el caso de rehabilitación o recalce de cimentaciones, sino también en la edificación de nueva planta. La situación actual parte del desconocimiento del campo de las inyecciones aplicadas a la edificación, y más en las actuaciones de recalce de cimentación, que afecta al funcionamiento del sistema, y a las dificultades para su ejecución y control por parte de los técnicos participantes. El desconocimiento, en general de esta temática por parte de los profesionales de la edificación, le da una mayor importancia al tema. Se plantea realizar una exposición que permita, poder establecer una documentación, no solo explicativa, sino justificativa del funcionamiento del sistema, que permita su difusión y comprensión por parte de los técnicos participantes en el proceso edificatorio.

    Full Text Available El artículo recorre la trayectoria de militantes argentinos, bolivianos, chilenos y uruguayos que desarrollaron una red regional de organizaciones armadas de izquierda. Los intercambios entre estas organizaciones que demoraran más de diez años, comenzaron con las redes de apoyo a la incursión del Che Guevara a Bolivia en 1966 y finalizaron en los tardíos setentas cuando el golpe de estado en Argentina canceló el último refugio en la región. Para entender la evolución que culminó en el desarrollo de una estrategia continental se examina la confluencia del ERP Argentino, el ELN Boliviano, el uruguayo MLN-Tupamaros y el chileno MIR a través de eventos críticos que definieron la experiencia de esta red de militantes: el impacto de la guerrilla boliviana del Che, los intercambios políticos y culturales desarrollados entre militantes de estas organizaciones en el Chile de Allende, y la creación de una organización regional llamada la Junta de Coordinación Revolucionaria. Este articulo usa una perspectiva transnacional para examinar un tema que hasta ahora ha sido examinado mayoritariamente desde una perspectiva nacional o comparativa. El artículo busca mostrar cómo la región fue un espacio central de experimentación en la constitución de identidades políticas. Asimismo, defiende que solo un enfoque transnacional puede ayudar a dar una más completa explicación acerca de la emergencia de estos movimientos políticos radicales durante el período

    Background: The introduction of diagnosis related groups for reimbursement of hospital services in Germany (g-drg) demands for a reconsideration of utilization of radiological products and costs related to them. Methods: Traditional cost accounting as approach to internal, department related budgets are compared with the accounting method of activity based costing (ABC). The steps, which are necessary to implement ABC in radiology are developed.Conclusions: The introduction of a process-oriented cost analysis is feasible for radiology departments. ABC plays a central role in the set-up of decentralized controlling functions within this institutions. The implementation seems to be a strategic challenge for department managers to get more appropriate data for adequate enterprise decisions. The necessary steps of process analysis can be used for other purposes (Certification, digital migration) as well. (orig.) [German] Hintergrund.

    Full Text Available A lo largo de los años distintas circunstancias han obligado al Gobierno peruano a declarar diversos Estados de Emergencia así como a recurrir a las Fuerzas Armadas para solventar graves alteraciones del orden público. Estas son medidas habilitadas por la Constitución que las confi gura como mecanismos tasados, limitados y predeterminados destinados a reestablecer el orden público de una forma compatible con el sistema de derechos y garantías constitucionales. Sin embargo en la práctica no dejan de sucederse denuncias acerca de excesos cometidos por las Fuerzas Armadas así como constantes vulneraciones de derechos. El presente trabajo pretende ofrecer herramientas para evitar tales excesos y vulneraciones de derechos, así como para delimitar las responsabilidades que el Presidente y los ministros deben asumir en tales casos. Para ello se parte de la consideración de que la declaración de Estado de Excepcional, y en su caso la intervención militar, no implica la suspensión de la Constitución, ni del Estado de Derecho, ni del régimen de derechos y libertades, ni de garantías. No implica el establecimiento de la arbitrariedad, no habilita a la adopción de cualquier medida, no justifi ca que el Estado pueda incumplir con sus obligaciones de respetar y garantizar los derechos de las personas. Así también se considera que durante la vigencia del Estado de Emergencia la Constitución no otorga a las Fuerzas Armadas ninguna competencia, atribución o prerrogativa especial y, aunque habilita a la suspensión de un número concreto de derechos, ello no signifi ca que se pueda actuar arbitrariamente o que pueda vulnerar los derechos no afectados por la suspensión. En tal caso las Fuerzas Armadas sólo pasan a asumir el desempeño de una función (orden público pero ello no implica que el orden público se militarice, sino que sim- plemente dichas Fuerzas Armadas pasan a desarrollar las funciones que, por las graves circunstancias, la

    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.)

    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.

    A model for carcinogenesis (the TSCE model) was applied in order to examine the effects of &apos;&apos;Low-dose hypersensitivity (LDH)&apos;&apos; and the &apos;&apos;Bystander effect (BE)&apos;&apos; on the derivation of radiation related cancer mortality risks. LDH has been discovered to occur in the inactivation of cells after acute exposure to low LET radiation. A corresponding version of the TSCE model was applied to the mortality data on the Abomb survivors from Hiroshima and Nagasaki. The BE has been mainly observed in cells after exposure to high LET radiation. A Version of the TSCE model which included the BE was applied to the data on lung cancer mortality from the workers at the Mayak nuclear facilities who were exposed to Plutonium. In general an equally good description of the A-bomb survivor mortality data (for all solid, stomach and lung tumours) was found for the TSCE model and the (conventional) empirical models but fewer parameters were necessary for the TSCE model. The TSCE model which included the effects of radiation induced cell killing resulted in non-linear dose response curves with excess relative risks after exposure at young ages that were generally lower than in the models without cell killing. The main results from TSCE models which included cell killing described by either conventional survival curves or LDH were very similar. A sub multiplicative effect from the interaction of smoking and exposure to plutonium was found to result from the analysis of the Mayak lung cancer mortality data. All models examined resulted in the predominant number of Mayak lung cancer deaths being ascribed to smoking. The interaction between smoking and plutonium exposures was found to be the second largest effect. The TSCE model resulted in lower estimates for the lung cancer excess relative risk per unit plutonium dose than the empirical risk model, but this difference was not found to be statistically significant. The excess relative risk dose responses

    To scrutinize the disorders caused by human mutant apoE7/apoE4, human apoE4 and E7 transgenic mice were established with microinjection technique to examine molecular genetic phenomena in vivo. The integration and expression of h-apoE mutant genes in transgenic mice were determined with Southern blot, Northern blot and ELISA. The current studies indicated that the transgenes and the phenotypes regarding expression of transgenes could be transmitted stably in transgenic lines. The levels of serum lipid in transgenic mice showed the characteristics of hyperlipidemia. Besides, behavior tests demonstrated the degeneration of learning and memory in transgenic mice. Short life span was observed in 2 transgenic lines. After fed with high lipid food high serum lipid was found both in normal and transgenic mice, but their mechanism regulating lipid metabolism was different. It was also verified that the human apoE mutants located at either N-terminal or C-terminal had the same pathogenesis regarding disorders of lipid metabolism in murine.

    Global sea-surface temperature maps show that mass coral-reef bleaching episodes between 1983 and 1991 followed positive anomalies more than 1 deg C above long-term monthly averages (&apos;&apos;hot spots&apos;&apos;) during the preceding warm season. Irregular formation, movement, and disappearance of hot spots make their detailed long-term prediction impossible, but they can be tracked in real time from satellite data. Monitoring of ocean hot spots and of coral bleaching is needed if the Framework Convention of Climate Change is to meet its goal of protecting the most temperature sensitive ecosystems. 47 refs, 3 figs

    By using the analytical superasymmetric fission model it is shown that all &apos;'stable'&apos; nuclei lighter than lead with Z>40 are metastable relative to the spontaneous emission of nuclear clusters. An even-odd effect is included in the zero point vibration energy. Half-lives in the range 10/sup 40/--10/sup 50/ s are obtained for Z>62. The region of metastability against these new decay modes is extended beyond that for ..cap alpha.. decay and in some cases, in the competing region, the emission rates for nuclear clusters are larger than for ..cap alpha.. decay.

    Waste managers are increasingly expected to provide good security for the hazardous materials they marshal. Good security requires, among other things, effective tamper and intrusion detection. We have developed and demonstrated a new method for tamper and intrusion detection which we call the &apos;&apos;town crier method&apos;&apos;. It avoids many of the problems and vulnerabilities associated with traditional approaches, and has significant advantages for hazardous waste transport. We constructed two rudimentary town crier prototype systems, and tested them for monitoring cargo inside a truck. Preliminary results are encouraging.

    With the new Energy Economy Act coming into force and regulation authorities being established, the public utilities providing gas and electricity are starting the implementation of regulation. This creates a new field of activity: The regulation management. The regulation manager in a public utility has a wide field of functions. He or she is responsible for the organisation of the enterprise with regard to the regulation authority. He must coordinate various divisions of the enterprise taking into consideration the interest of the regulation authority and take steps to form a common understanding. The meeting called &apos;&apos;Focus on Regulation Management&apos;&apos; provides an insight into the most important tasks of a regulation manager, giving information useful for establishing an efficient regulation management system. In the first part of the meeting, the basics and tasks of regulation management and the legal protection towards the regulation authorities are dealt with. Furthermore, the president of the states&apos; committee in the BNetzA, Mr. Peter Franke, will introduce the present fields of activity, reporting about first experiences gained with the network cost requests. In the second part, practitioners from the enterprises report about their experiences with the implementation of regulation management. This includes especially data management, an effective reporting system and the implementation of a relationship management between the regulation authority and the enterprise. The meeting closes with a speech on the subject of comparing methods and benchmarking in the network.

    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.

    The importance of the intake positioning height above the floor level on the performance of &apos;'ductless'&apos; personalized ventilation (&apos;'ductless'&apos; PV) in conjunction with displacement ventilation (DV) was examined with regard to the quality of inhaled air and of the thermal comfort provided. A typical office room with two workstations positioned one behind the other was arranged in a full-scale room. Each workstation consisted of a table with an installed &apos;'ductless'&apos; PV system, PC, desk lamp and seated breathing thermal manikin. The &apos;'ductless'&apos; PV system sucked the clean and cool displacement air supplied over the floor at four different heights, i.e. 2, 5, 10 and 20 cm and transported it direct to the breathing level. Moreover, two displacement airflow rates were used with a supply temperature adjusted in order to maintain an exhaust air temperature of 26 C. Two pollution sources, namely air exhaled by one of the manikins and passive pollution on the table in front of the same manikin were simulated by constant dosing of tracer gases. The results show that the positioning of a &apos;'ductless'&apos; PV intake height up to 0.2 m above the floor will not significantly influence the quality of inhaled air and thermal comfort.

    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

    The final disposal of nuclear wastes is called &apos;'messy'&apos; or &apos;'wicked'&apos; in the political science literature. The highly complicated problems are characterized by a number of features such as intra- and inter-generational aspects and ethical questions. In the case of stakeholders the differences concern ideologies, interests, merits and preferences that cause conflicts. The search for solutions is complicated due to interacting political, social, ecologic, economic and technical aspects. The concepts &apos;&apos;wicked problems&apos;&apos; and &apos;'multi-level-governance'&apos; are promising approaches to solve the complicated situation.

    Full Text Available In this paper, several methods are presented and compared in order to choose the best digital algorithm to recognize the diatoms species. A digital system of invariant correlation to position and rotation is constructed. Based in a binary ring mask an average signature filter for a selected image is produced in four different ways and compared with variance spectrum modified methodology using four different ways too. It is conclusive that the best methodology for this case is presented in the first method when the binary mask with a nonlinear filter is used without high frequencies enhanced in the variance spectrum of the input image using an average filter of 10 input rotated images. Moreover the confidence level for this case was 100%. The second best case was for the average filter f18, with the same confidence level, but where the difference in time is more than one minute. One of the advantages of these kinds of methodologies is that an entire process can be repeated in the same way without mistakes and the diatoms images are kept save in a hard disk of the computer, so everybody can see again the diatom information of some special localization of the ocean.En este artículo, se presentan y se comparan varios métodos para escoger el mejor algoritmo digital para reconocer especies de diatomeas.

Estos cuatro diferentes modos de correlación se comparan con una nueva metodología de espectro de varianza modificada que también utiliza cuatro maneras distintas de correlación. Es concluyente que los mejores resultados corresponden al método que utiliza la máscara binaria con una firma promedio de 10 imágenes rotadas y el uso de un filtro no lineal y sin realce del contenido de frecuencias del espectro de

    Using the &apos;teleparallel&apos; equivalent of General Relativity as the gravitational sector, which is based on torsion instead of curvature, we add a canonical scalar field, allowing for a nonminimal coupling with gravity. Although the minimal case is completely equivalent to standard quintessence, the nonminimal scenario has a richer structure, exhibiting quintessence-like or phantom-like behavior, or experiencing the phantom-divide crossing. The richer structure is manifested in the absence of a conformal transformation to an equivalent minimally-coupled model.

    Dense cavitary &apos;'photopenia'&apos; was observed on 21 of 200 consecutive stress perfusion scintigrams. A prominent finding in many cases, it sometimes occupied only a portion of the region overlying the ventricular cavity, was often seen in some projections and not others, and was frequently adjacent to myocardial perfusion defects. To distinguish an etiology among reduced cavitary radioactivity, relatively increased background radioactivity, or reduced radioactivity in overlying myocardium, quantitative analysis of cavitary, lung and myocardial radioactivity was performed in patients with dense cavitary &apos;'photopenia,'&apos; with and without lung uptake, and compared with results from studies showing increased lung uptake without cavitary photopenia and with normal studies. The results showed that dense cavitary photopenia was related to reduced radioactivity in overlying myocardium. Correlative imaging studies performed with echocardiography and contrast ventriculography confirmed this relationship to myocardial scar in 15 of 21 patients in whom associated akinesis or dyskinesis was seen. Hence, dense cavitary photopenia on stress perfusion scintigraphy is due to a dense myocardial perfusion abnormality, and is often indicative of related scar and an associated severe contraction abnormality.

    The orthodox models devised to explain the apparent &apos;&apos;superluminal expansions&apos;&apos; observed in astrophysics - and here briefly summarized and discussed together with the experimental data - do not seem to be too much successful, especially when confronted with the most recent observations, suggesting complicated expansion patterns, even with possible accelerations. At this point it may be, therefore, of some interest to explore the possible alternative models in which actual Superluminal motions take place. To prepare the ground, we start from a variational principle, introduce the elements of a tachyon mechanics within special relativity, and argue about the expected behaviour of tachyonic objects when interacting (gravitationally, for instance) among themselves or with ordinary matter. We then review and develop the simplet &apos;&apos;Superluminal models&apos;&apos;, paying particular attention to the observations which they would give rise to. We conclude that some of them appear to be physically acceptable and are statistically favoured with respect to the orthodox ones.

    Continuously variable camphasers are now well established for modern spark-ignition engines in high-volume production. With the latest generation of camshaft adjustment systems using the vane-type actuator principle, it is possible to move rapidly and reliably through a large adjustment angle. The layout of these adjusting systems is very simple. The production costs are low in comparison to the first generation of camphasers using spur/helical gears to vary the valve timing. The new-generation systems are mechatronic, with the function depending on the coordination and tuning of hydraulic actuation and engine electronics. The term &apos;VaneCAM&apos; is used for the continuously variable systems of this new generation supplied by Hydraulik-Ring in Nuertingen, Germany. (orig.)

    Based on the PWR spent fuel composition data measured at JAERI, two kinds of simplified methods such as &apos;&apos;Equivalent Uniform Burnup&apos;&apos; and &apos;&apos;Equivalent Initial Enrichment&apos;&apos; have been introduced. And relevant evaluation curves have been prepared for criticality safety evaluation of spent fuel storage pool and transport casks, taking burnup of spent fuel into consideration. These simplified methods can be used to obtain an effective neutron multiplication factor for a spent fuel storage/transportation system by using the ORIGEN2.1 burnup code and the KENO-Va criticality code without considering axial burnup profile in spent fuel and other various factors introducing calculated errors. &apos;&apos;Equivalent Uniform Burnup&apos;&apos; is set up for its criticality analysis to be reactivity equivalent with the detailed analysis, in which the experimentally obtained isotopic composition together with a typical axial burnup profile and various factors such as irradiation history are considered on the conservative side. On the other hand, Equivalent Initial Enrichment&apos;&apos; is set up for its criticality analysis to be reactivity equivalent with the detailed analysis such as above when it is used in the so called fresh fuel assumption.

    We present a study on the invariant mass distribution of {pi}&apos;'{+-}{pi}'&apos;0 pairs produced in the process {tau}{yields}{pi}&apos;'{+-}{pi}'&apos;0{nu} . The analysis is based on a sample of 33,096 events collected by the L3 detector between 1991 and 1994. The data is not inconsistent with the hypothesis that the process is being mediated by the p(770) meson alone but is in better agreement with the inclusion of an extra {rho} resonance in the decay of the tau lepton.

  3. Novel action of apolipoprotein E (ApoE: ApoE isoform specifically inhibits lipid-particle-mediated cholesterol release from neurons

    2007-05-01

    Full Text Available Abstract Background Since the majority of apolipoprotein E (apoE existing in the cerebrospinal fluid is associated with high-density lipoprotein (HDL, one should focus on the role of the apoE-HDL complex rather than on that of free apoE in cholesterol metabolism in the central nervous system. However, the apoE-isoform-specific effect of apoE-HDL on cholesterol transport remains unclarified. Results Here we show that apoE3-HDL induced a marked cholesterol release from neurons, while apoE4-HDL induced little. To elucidate the mechanism underlying this phenomenon, we used a complex of lipid emulsion (EM with recombinant apoE3 or apoE4 (apoE-EM at various apoE concentrations. When a small number of apoE molecules were associated with EM, apoE3- and apoE4-EM, induced a marked cholesterol release to a level similar to that induced by EM alone. However, when apoE at given concentrations was incubated with EM, apoE3-EM induced a marked cholesterol release, while apoE4-EM induced little. Under these conditions, a greater number of apoE4 molecules were associated with EM than apoE3 molecules. When an increasing number of apoE molecules were associated with EM, both apoE3-EM and apoE4-EM induced little cholesterol release. Preincubation with β-mercaptoethanol increased the number of apoE3 molecules associated with EM similar to that of apoE4 molecules, indicating that the presence (apoE3 or absence (apoE4 of intermolecular disulfide bond formation is responsible for the association of a greater number of apoE4 molecules to EM than apoE3 molecules. Conclusion These results suggest that although apoE and a lipid particle are lipid acceptors, when apoE and a lipid particle form a complex, apoE on the particle surface inhibits the lipid particle-mediated cholesterol release from cells in an apoE-concentration-dependent manner.

  5. A &apos;'Toolbox'&apos;21 Equivalent Process for Safety Analysis Software

    2004-04-30

    Defense Nuclear Facilities Safety Board (DNFSB) Recommendation 2002-1 (Quality Assurance for Safety-Related Software) identified a number of quality assurance issues on the use of software in Department of Energy (DOE) facilities for analyzing hazards, and designing and operating controls that prevent or mitigate potential accidents. The development and maintenance of a collection, or &apos;'toolbox,'&apos; of multiple-site use, standard solution, Software Quality Assurance (SQA)-compliant safety software is one of the major improvements identified in the associated DOE Implementation Plan (IP). The DOE safety analysis toolbox will contain a set of appropriately quality-assured, configuration-controlled, safety analysis codes, recognized for DOE-broad, safety basis applications. Currently, six widely applied safety analysis computer codes have been designated for toolbox consideration. While the toolbox concept considerably reduces SQA burdens among DOE users of these codes, many users of unique, single-purpose, or single-site software may still have sufficient technical justification to continue use of their computer code of choice, but are thwarted by the multiple-site condition on toolbox candidate software. The process discussed here provides a roadmap for an equivalency argument, i.e., establishing satisfactory SQA credentials for single-site software that can be deemed &apos;'toolbox-equivalent'&apos;. The process is based on the model established to meet IP Commitment 4.2.1.2: Establish SQA criteria for the safety analysis &apos;'toolbox'&apos; codes. Implementing criteria that establish the set of prescriptive SQA requirements are based on implementation plan/procedures from the Savannah River Site, also incorporating aspects of those from the Waste Isolation Pilot Plant (SNL component) and the Yucca Mountain Project. The major requirements are met with evidence of a software quality assurance plan, software requirements and

    An extremely rare example of an elongated (3 cm) osteoid osteoma is presented. The tumor demonstrated three focal enlargements connected by narrow areas, suggesting a &apos;&apos;string of beads&apos;&apos; in appearance. The elongated shape suggested the possibility that lesional tissue was stretched in a longitudinal fashion as a result of the rapid skeletal growth. The tumor closest to the growth plate was densely ossified, while the furthest lesion was almost completely lytic, suggesting that the tumor enlarged in a centripetal direction. This case is believed to illustrate a continuum from solitary to multicentric osteoid osteoma. The tumor was treated successfully with three separate percutaneous radiofrequency ablations during a single session. (orig.)

    EDF intends to achieve successful and cost-effective dismantling of its obsolete nuclear plants. To reach this goal, EDF is currently extending its &apos;'as-built'&apos; 3-D modelling system to also include the location and characteristics of gamma sources in the geometrical models of its nuclear installations. The resulting system (called RADMAP) is a complete CAD chain covering 3-D and gamma data acquisitions, CAD modelling and exploitation of the final model. Its aim is to describe completely the geometrical and radiological state of a particular nuclear environment. This paper presents an overall view of RADMAP. The technical and functional characteristics of each element of the chain are indicated and illustrated using real (EDF) environments/applications. (author)

    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.

    &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.

    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.

  18. ApoE isoform-dependent changes in hippocampal synaptic function

    2009-05-01

    Full Text Available Abstract The lipoprotein receptor system in the hippocampus is intimately involved in the modulation of synaptic transmission and plasticity. The association of specific apoE isoform expression with human neurodegenerative disorders has focused attention on the role of these apoE isoforms in lipoprotein receptor-dependent synaptic modulation. In the present study, we used the apoE2, apoE3 and apoE4 targeted replacement (TR mice along with recombinant human apoE isoforms to determine the role of apoE isoforms in hippocampus area CA1 synaptic function. While synaptic transmission is unaffected by apoE isoform, long-term potentiation (LTP is significantly enhanced in apoE4 TR mice versus apoE2 TR mice. ApoE isoform-dependent differences in LTP induction require NMDA-receptor function, and apoE isoform expression alters activation of both ERK and JNK signal transduction. Acute application of specific apoE isoforms also alters LTP induction while decreasing NMDA-receptor mediated field potentials. Furthermore, acute apoE isoform application does not have the same effects on ERK and JNK activation. These findings demonstrate specific, isoform-dependent effects of human apoE isoforms on adult hippocampus synaptic plasticity and highlight mechanistic differences between chronic apoE isoform expression and acute apoE isoform exposure.

    To determine the potential of novel gradient echo parameters, &apos;&apos;Black Bone&apos;&apos; MRI as an alternative to CT in the identification of normal and prematurely fused cranial sutures both in 2D and 3D imaging. Thirteen children with a clinical diagnosis of craniosynostosis underwent &apos;&apos;Black Bone&apos;&apos; MRI in addition to routine cranial CT. &apos;&apos;Black Bone&apos;&apos; datasets were compared to CT and clinical findings. &apos;&apos;Black Bone&apos;&apos; imaging was subsequently used to develop 3D reformats of the craniofacial skeleton to enhance further visualisation of the cranial sutures. Patent cranial sutures were consistently identified on &apos;&apos;Black Bone&apos;&apos; MRI as areas of increased signal intensity. In children with craniosynostosis the affected suture was absent, whilst the remaining patent sutures could be visualised, consistent with CT and clinical findings. Segmentation of the &apos;&apos;Black Bone&apos;&apos; MRI datasets was successful with both threshold and volume rendering techniques. The cranial sutures, where patent, could be visualised throughout their path. Patent cranial sutures appear as areas of increased signal intensity on &apos;&apos;Black Bone&apos;&apos; MRI distinct from the cranial bone, demonstrating considerable clinical potential as a non-ionising alternative to CT in the diagnosis of craniosynostosis.

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

    Objectives ApoE ε4 is associated with adverse health conditions that negatively impact the quality of life (QOL). The relationship between ApoE ε4 and QOL has not been explored in the oldest old. Our study aimed to examine ApoE in the oldest old, and explore its association with QOL. Design Cross-sectional cohort study. Setting A medium sized community in Olmsted County, Minnesota, USA. Participants 90–99 year old individuals living independently or in long term care environments. Measurements We collected demographic information and measured cognitive function (Short Test of Mental Status [STMS], Mini-Mental State Examination [MMSE], Mattis Dementia Rating Scale [DRS]), QOL (Linear Analogue Self Assessment [LASA]) and ApoE distribution. Subjects were classified as cognitively normal, mild cognitive impairment (MCI), dementia (DEM), or dementia with stroke and/or parkinsonism (DEMSP). Regression model was used to assess the predictors of QOL. Results 121 subjects (45 cognitively normal, 13 MCI, 34 DEM, 29 DEMSP) aged 90–99,106 (87.6 %) females, were included. Frequency of ApoE ε3 allele was highest [194 (80.2%): ε2/3 18, ε3/3 77, ε3/4 22] followed by ApoE ε4 [25 (10.3%): ε2/4 3, ε3/4 22] and ApoE ε2 [23 (9.5%; ε2/2 1, ε2/3 18, ε2/4 3]. None of the subjects carried ApoE ε4/4 genotype. QOL was similar between ApoE ε4 carrier and non-carriers. Physical well-being, emotional well-being, intellectual well-being, social connectedness and coping ability were positively associated with QOL, whereas male gender, DEMSP, pain frequency and pain severity were negatively associated. Conclusions The most common ApoE in the oldest old was ε3/3 genotype and ε3 allele. No association was found between ApoE ε4 and QOL. However, those with high physical, emotional and intellectual well being, social connectedness and coping ability had the highest overall QOL. PMID:22863665

    The apolipoprotein E4 (ApoE4) allele is the strongest genetic risk factor for developing sporadic Alzheimer's disease (AD). However, the mechanisms underlying the pathogenic nature of ApoE4 are not well understood. In this study, we have found that ApoE proteins are critical determinants of brain phospholipid homeostasis and that the ApoE4 isoform is dysfunctional in this process. We have found that the levels of phosphoinositol biphosphate (PIP2) are reduced in postmortem human brain tissues of ApoE4 carriers, in the brains of ApoE4 knock-in (KI) mice, and in primary neurons expressing ApoE4 alleles compared with those levels in ApoE3 counterparts. These changes are secondary to increased expression of a PIP2-degrading enzyme, the phosphoinositol phosphatase synaptojanin 1 (synj1), in ApoE4 carriers. Genetic reduction of synj1 in ApoE4 KI mouse models restores PIP2 levels and, more important, rescues AD-related cognitive deficits in these mice. Further studies indicate that ApoE4 behaves similar to ApoE null conditions, which fails to degrade synj1 mRNA efficiently, unlike ApoE3 does. These data suggest a loss of function of ApoE4 genotype. Together, our data uncover a previously unidentified mechanism that links ApoE4-induced phospholipid changes to the pathogenic nature of ApoE4 in AD.

    In high-energy astrophysics, it is common practice to account for the background overlaid with counts from the source of interest with the help of auxiliary measurements carried out by pointing off-source. In this &apos;'on/off'&apos; measurement, one knows the number of photons detected while pointing toward the source, the number of photons collected while pointing away from the source, and how to estimate the background counts in the source region from the flux observed in the auxiliary measurements. For very faint sources, the number of photons detected is so low that the approximations that hold asymptotically are not valid. On the other hand, an analytical solution exists for the Bayesian statistical inference, which is valid at low and high counts. Here we illustrate the objective Bayesian solution based on the reference posterior and compare the result with the approach very recently proposed by Knoetig, and discuss its most delicate points. In addition, we propose to compute the significance of the excess with respect to the background-only expectation with a method that is able to account for any uncertainty on the background and is valid for any photon count. This method is compared to the widely used significance formula by Li and Ma, which is based on asymptotic properties.

    The current state of the art solution processed organic photovoltaic (OPV) cells are based on the bulk heterojunction (BHJ) architecture, consisting of an active layer, in which the donor and the acceptor material are dissolved in a common solvent. In this report, we show that by sequential processing of the active components and by subsequent annealing a &apos;'pseudo-bilayer'&apos; can be formed which results in an enhanced nanomorphology for efficient charge generation and extraction. The enhanced nanomorphology arises from the inter-diffusion of the PCBM nanoparticles into a layer of pre-organised polymer P3HT instead of a phase separation that happens at the time of spin-coating and annealing in the case of conventional BHJ devices. To get a further insight into the inter-diffusion process, TOF-SIMS depth profiling and XPS measurements were carried out for different thermal annealing treatments of these pseudo-bilayer devices, which show full inter-diffusion after only seconds of annealing at 140 C. The optimised photovoltaic devices that were fabricated showed an efficiency of 4.1%. (orig.)

    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.

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

    ApoE4 (apolipoprotein E4) is the major known genetic risk factor for AD (Alzheimer's disease). In most clinical studies, apoE4 carriers account for 65-80% of all AD cases, highlighting the importance of apoE4 in AD pathogenesis. Emerging data suggest that apoE4, with its multiple cellular origins and multiple structural and biophysical properties, contributes to AD in multiple ways either independently or in combination with other factors, such as Aβ (amyloid β-peptide) and tau. Many apoE mouse models have been established to study the mechanisms underlying the pathogenic actions of apoE4. These include transgenic mice expressing different apoE isoforms in neurons or astrocytes, those expressing neurotoxic apoE4 fragments in neurons and human apoE isoform knock-in mice. Since apoE is expressed in different types of cells, including astrocytes and neurons, and in brains under diverse physiological and/or pathophysiological conditions, these apoE mouse models provide unique tools to study the cellular source-dependent roles of apoE isoforms in neurobiology and in the pathogenesis of AD. They also provide useful tools for discovery and development of drugs targeting apoE4's detrimental effects.

    The &apos;'forest'&apos; of absorption lines observed in the spectrum of distant quasars is interpreted in light of the adiabatic (pancake) theory for the origin and evolution of structure in the universe. The hidden mass might reside in neutrino-like particles (perhaps unstable) having a rest mass of about 60--100 eV. Opportunities for testing the hypothesis observationally are discussed.

    The recent conclusion that in a turbulent, collisionless plasma &apos;&apos;magnetic transport including quasilinear magnetic flutter transport ... does not contribute to the relaxation of (f), and thus is not responsible for electron energy or momentum transport&apos;&apos; is shown to be incorrect for a variety of situations of physical interest, including saturation by quasilinear plateau formation, induced scattering, and, most importantly, conventional mode coupling. The well-established theory of the mean infinitesimal response function and the spectral balance equation provides a unifying framework for understanding the above conclusion. In particular, the cancellations which lead to their conclusion are special cases of well-known relationships between the response function, particle propagator, and dielectric function. A more general, concise, and manifestly gauge-invariant algebraic derivation of the cancellations is given. Though the cancellations occur in a certain limit, these conclusions do not follow in general: The picture of steady-state turbulence as consisting of small-scale &apos;'incoherent'&apos; ballistic &apos;'clumps'&apos; shielded by long-wavelength &apos;'coherent'&apos; dielectric response is physically misleading and mathematically incomplete, as it ignores or mistreates the often dominant process of renormalized n-wave coupling. Thus, when ion nonlinearities are considered, formulas for the magnetic contribution to transport emerge which are quite similar to the quasilinear one. Furthermore, limits are possible in which all or part of the noise can be negligible, yet in which the total fluctuation spectrum remains finite. 56 refs.

    To most audiences, deterrence has been interconnected with nuclear weapons whose purpose had been to deter a Soviet attack. But, the Soviet Union has been gone for almost a decade. President George W. Bush has stated that Russia is not an enemy of the US and the numbers of nuclear weapons can be dramatically reduced. It is important to note that deterrence has always transcended nuclear weapons. The US&apos; first line of deterrence has been its formidable conventional warfare capability, designed to prevent conflict and win wars if necessary. The role of nuclear weapons has been to deter the,use of nuclear weapons and other weapons of mass destruction against U.S. interests during the conduct of conventional warfare and to ensure our ability to inflict massive destruction on any who would use nuclear weapons, or other weapons of mass destruction, against us. With regard to the Soviet Union, the threat of the use of nuclear weapons was a critical component of our deterrent to prevent massive Soviet conventional attack against our allies in Europe. However, the events of September 11, 2001 make clear that we have not convinced all who seek to harm us that we will be able to respond in a manner to make them wish they had not even tried. The September 11 attacks, as well as other past conflicts, do not mean that deterrence has failed-it remains effective against the threats for which it was designed. We have known there are other threats for which we did not have a credible deterrent. The challenge is to sustain deterrence against the classic threats as they evolve in technical sophistication while remaining alert to the need to evaluate continuously our ability to deter previously unforeseen challenges. How then should we be looking at deterrence as we consider fifteen or so years in the future, say to about 2015? What will be the role of nuclear weapons and other instruments of mass destruction in the future? What should the US be doing to prepare for the future? In

    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.)

    Full Text Available Atherosclerosis and apolipoprotein E ε4 (APOE4 genotype are risk factors for Alzheimer’s disease (AD and cardiovascular disease (CVD. Sex differences exist in prevalence and manifestation of both diseases. We investigated sex differences respective to aging, focusing on cognitive parameters in apoE4 and apoE knockout (ko mouse models of AD and CVD. Presynaptic density and neurogenesis were investigated immunohistochemically in male and female apoE4, apoE ko, and wild-type mice. Middle-aged female apoE4 mice showed decreased presynaptic density in the inner molecular layer of the dentate gyrus of the hippocampus. Middle-aged female apoE ko mice showed a trend towards increased neurogenesis in the hippocampus compared with wild-type mice. No differences in these parameters could be observed in middle-aged male mice. Specific harmful interactions between apoE4 and estrogen could be responsible for decreased presynaptic density in female apoE4 mice. The trend of increased neurogenesis found in female apoE ko mice supports previous studies suggesting that temporarily increased amount of synaptic contacts and/or neurogenesis is a compensatory mechanism for synaptic failure. To our knowledge, no other studies investigating presynaptic density in aging female apoE4 or apoE ko mice are available. Sex-specific differences between APOE genotypes could account for some sex differences in AD and CVD.

    Apolipoprotein E4 (apoE4), the most prevalent genetic risk factor for Alzheimer's disease (AD), is associated with neuronal and vascular impairments. Recent findings suggest that retina of apoE4 mice have synaptic and functional impairments. We presently investigated the effects of apoE4 on retinal and choroidal vasculature and the possible role of VEGF in these effects. There were no histological differences between the retinal and choroidal vasculatures of naïve apoE3 and apoE4 mice. In contrast, laserdriven choroidal injury induced higher levels of choroidal neovascularization (CNV) in apoE4 than in apoE3 mice. These effects were associated with an inflammatory response and with activation of the Muller cells and asrocytic markers gluthatione synthetase and GFAP, all of which were more pronounced in the apoE4 mice. CNV also induced a transient increase in the levels of the synaptic markers synaptophysin and PSD95 which were however similar in the apoE4 and apoE3 naive mice. Retinal and choroidal VEGF and apoE levels were lower in naïve apoE4 than in corresponding apoE3 mice. In contrast, VEGF and apoE levels rose more pronouncedly following laser injury in the apoE4 than in apoE3 mice. Taken together, these findings suggest that the apoE4-induced retinal impairments, under basal conditions, may be related to reduced VEGF levels in the eyes of these mice. The hyper-neovascularization in the apoE4 mice might be driven by increased inflammation and the associated surge in VEGF following injury. Retinal and choroidal VEGF and apoE levels were lower in naïve apoE4 than in corresponding apoE3 mice.

    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.)

    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

    Short gamma-ray bursts (SGRBs) are among the most luminous explosions in the universe and their origin still remains uncertain. Observational evidence favors the association with binary neutron star or neutron star-black hole (NS-BH) binary mergers. Leading models relate SGRBs to a relativistic jet launched by the BH-torus system resulting from the merger. However, recent observations have revealed a large fraction of SGRB events accompanied by X-ray afterglows with durations ∼10{sup 2}-10{sup 5} s, suggesting continuous energy injection from a long-lived central engine, which is incompatible with the short (≲ 1 s) accretion timescale of a BH-torus system. The formation of a supramassive NS, resisting the collapse on much longer spin-down timescales, can explain these afterglow durations, but leaves serious doubts on whether a relativistic jet can be launched at the merger. Here we present a novel scenario accommodating both aspects, where the SGRB is produced after the collapse of a supramassive NS. Early differential rotation and subsequent spin-down emission generate an optically thick environment around the NS consisting of a photon-pair nebula and an outer shell of baryon-loaded ejecta. While the jet easily drills through this environment, spin-down radiation diffuses outward on much longer timescales and accumulates a delay that allows the SGRB to be observed before (part of) the long-lasting X-ray signal. By analyzing diffusion timescales for a wide range of physical parameters, we find delays that can generally reach ∼10{sup 5} s, compatible with observations. The success of this fundamental test makes this &apos;'time-reversal'&apos; scenario an attractive alternative to current SGRB models.

    This paper attempts to interpret OPEC&apos;s decision making process by analysing the political-economic behaviour of the Member Countries of the Organization of the Petroleum Exporting Countries. The economic objectives of OPEC members is first discussed under the hypothesis of cooperation versus competition. A loose marketing arrangement among OPEC members is then assumed. Both approaches, pure economics and Real-politik lead to the same conclusion: the likelihood of a volatile price increase.

  4. Extracellular proteolysis of apolipoprotein E (apoE by secreted serine neuronal protease.

    Directory of Open Access Journals (Sweden)

    Irfan Y Tamboli

    Full Text Available Under normal conditions, brain apolipoprotein E (apoE is secreted and lipidated by astrocytes, then taken up by neurons via receptor mediated endocytosis. Free apoE is either degraded in intraneuronal lysosomal compartments or released. Here we identified a novel way by which apoE undergoes proteolysis in the extracellular space via a secreted neuronal protease. We show that apoE is cleaved in neuronal conditioned media by a secreted serine protease. This apoE cleavage was inhibited by PMSF and α1-antichymotrypsin, but not neuroserpin-1 or inhibitors of thrombin and cathepsin G, supporting its identity as a chymotrypsin like protease. In addition, apoE incubation with purified chymotrypsin produced a similar pattern of apoE fragments. Analysis of apoE fragments by mass spectrometry showed cleavages occurring at the C-terminal side of apoE tryptophan residues, further supporting our identification of cleavage by chymotrypsin like protease. Hippocampal neurons were more efficient in mediating this apoE cleavage than cortical neurons. Proteolysis of apoE4 generated higher levels of low molecular weight fragments compared to apoE3. Primary glial cultures released an inhibitor of this proteolytic activity. Together, these studies reveal novel mechanism by which apoE can be regulated and therefore could be useful in designing apoE directed AD therapeutic approaches.

    Full Text Available Este artigo procura examinar as estratégias discursivas utilizadas pelos movimentos a favor e contra o microdesarmamento no Brasil através da análise dos materiais de campanha das duas frentes no Referendo sobre a Proibição do Comércio de Armas de Fogo e Munições que teve lugar em outubro de 2005. A análise aponta para a utilização de representações e estratégias de mobilização do voto assentes em construções sexuadas das experiências e condutas de mulheres e de homens relativamente à probabilidade, lugares e protagonistas de vitimação armada, à conceção e ao exercício da legítima defesa enquanto direito do “cidadão de bem” e/ou privilégio. O estudo e a discussão destas representações são essenciais, uma vez que estas influenciam a forma como a violência e a (insegurança é imaginada e percebida e, em especial a forma como, por sua vez, condicionam as políticas de combate e prevenção da violência.

    Full Text Available O trabalho propõe-se a demonstrar porque desde 1979 foi possível aos militares brasileiros atuarem como veto players sempre que entrou em debate a revisão da Lei de Anistia. Nossa hipótese é que esse poder de veto explica-se pela existência de uma grande autonomia militar antes, durante e depois da ditadura, associada aos baixos níveis de respeito aos direitos humanos na sociedade brasileira e ao baixo interesse do Congresso e do governo em geral pelo tema das Forças Armadas.The study aims to show why since 1979 the Brazilian military had been able to act as veto players whenever the debate about Amnesty Law was argued. Our hypothesis is that this veto power is explained by the existence of a large military autonomy before, during and after the dictatorship, associated with low levels of human rights culture in Brazilian society and the low interest of Congress and government in general about Armed Forces issues.

    The folklore notion of the &apos;&apos;Non-Locality of Quantum Mechanics&apos;&apos; is examined from the point of view of hidden-variables theories according to Belinfante&apos;s classification in his Survey of Hidden Variables Theories. It is here shown that in the case of EPR, there exist hidden variables theories that successfully reproduce quantum-mechanical predictions, but which are explicitly local. Since such theories do not fall into Belinfante&apos;s classification, we propose an expanded classification which includes similar theories, which we term as theories of the &apos;'third'&apos; kind. Causal implications of such theories are explored. (orig.)

    Full Text Available The stability of phlogiston in eighteenth-century French chemistry depended not on its role as a comprehensive theory, but on its operational (instrumental, theoretical, and philosophical (speculative identities that were forged in different contexts, yet were interwoven to designate a single substance. It was as &apos;real&apos; as any other chemical substance to the degree that it was obtained through material operations, occupied a place in the theoretical edifice of the affinity table, and was endowed with a corpuscular ontology. Lavoisier labeled it as an &apos;imaginary&apos; substance because it offered a unique resistance to his vision of the new chemistry based on &apos;metric&apos; measurements and algebraic representations.

    2010-07-01

    The aim of this paper is to outline the NDA National Graduate Programme (nuclear graduates). The NDA has a remit under the Energy Act (2004) &apos;to maintain and develop the skills for decommissioning and nuclear clean-up&apos;. Although current research is now being reviewed, there is significant evidence to suggest that the age profile in the Site Licence Companies is skewed towards older workers and there is likely to be a skill shortage in 3-5 years. As nuclear clean-up is a national issue; skill shortages also become a national issue in a very real sense. In addition, evidence suggests that the industry needs to be constantly challenged in order to achieve its targets for decommissioning. The NDA has a unique position under the Act. It is both a strategic overseer and direct employer. To this end the &apos;National Graduate Programme&apos; is aligned to both the NDA&apos;s previous succession plans and the needs of the industry. Industry needs leadership that challenges the status quo and moves the UK nuclear industry to become best in class; Industry needs a dedicated to programme to address skills shortages and difficult to recruit areas such as, but not exclusively, estimators, schedulers, contract managers, site engineers, decommissioning technicians, safety monitors; The NDA has indicated a &apos;commercial and politically savvy&apos; cohort is required to meet its own internal challenges and to ensure sustainability in its own workforce, and to be sensitive to the needs of customers and suppliers alike; Need to create a more diversified workforce in the nuclear industry and also plan for new skills evolving from research and development breakthroughs; Need to ensure that Tier 1, 2, 3 and 4 contractors invest in the leadership and skills for the future. World Class - delivery will be benchmarked against UK based multinational companies who operate in a global graduate attraction and development marketplace. The graduates targeted will be from leading

  11. Why are effective potentials &apos;soft&apos;?

    This paper is concerned with effective potentials W{sub 1}(R) between interacting supramolecular particles separated by a distance R. We focus on the question of why these potentials are typically &apos;soft&apos;, i.e., remain finite for R {yields} 0 and vary more weakly with R than the underlying interatomic interaction potentials. On the basis of a general expression linking W{sub 1}(R) to the free energy F of the supramolecular system we investigate the origin of the apparent &apos;softness&apos; of W{sub 1}(R) by considering a number of special model systems, starting with an atom and a diatomic molecule. This simple model already yields a W{sub 1}(R) that is finite at R = 0, but W{sub 1}(R) does not exhibit the slowly varying character typical of effective potentials for realistic systems. We then show that the larger length scale is recovered when one introduces both many-body interactions and thermal fluctuations within the framework of a &apos;toy model&apos;, that is disc-shaped supramolecular units composed of thermalized configurations of Lennard-Jones atoms. In this case, W{sub 1}(R) varies so slowly that it can be parametrized by estimating the free energy change associated with the overlap of the discs. The resulting overlap approximation to W{sub 1}(R) behaves qualitatively like ad hoc effective potentials used in mesoscale simulations, such as dissipative particle dynamics. Indeed, on the basis of Monte Carlo simulations and a solution of hypernetted chain integral equations, we find that fluids interacting via DPD and overlap potentials have very similar structural and thermophysical properties. Moreover, the &apos;overlap&apos; fluid (like other &apos;effective&apos; fluids) turns out to be so &apos;soft&apos; that its properties, particularly at high densities, can be very well estimated by a mean-field treatment.

    Full Text Available The last war destroyed a large number of civil works, among which were the Berlin bridges. As the number of these was considerable, it was decided to improve on the original designs and methods of construction, taking advantage of new materials and prestressing techniques. Of the 84 reconstructed bridges, 24 of them have been made in prestressed concrete. This emphasizes what considerable importance was attached to this constructional method at a time when this technology had not yet reached its present day mature development. The rebuilt bridges have spans varying between 25 and 100 ms. Their foundations differ considerably in each particular case. Some consist of pile structures, others are of sheet piling, and others again are caissons. At present the most important prestressed bridge in Berlin is the Disching bridge, which runs over the Havel, and carries the road to Spandau. Its single span is 94 ms long, and the ratio of rise to span is 1/63.1.La última guerra mundial destruyó una serie de obras públicas, entre las cuales se hallaban muchos puentes de Berlín. Como el número de puentes destruidos es considerable, se pensó en mejorar las obras originales y los métodos de construcción, para lo cual se contaban con nuevos materiales y la técnica del pretensado, actualmente en estado de madurez. De las 84 obras que se han reconstruido, 24 son de hormigón pretensado. Esto pone de relieve la importancia que se le dio a este sistema en aquellos momentos en que la técnica de este tipo de construcciones no había alcanzado todavía el actual desarrollo. Los puentes reconstruidos tienen luces que varían de 25 a 100 metros. Los cimientos de estas obras son muy distintos y variados: unos están formados por tablestacas, otros se apoyan sobre pilotes y, finalmente, otros, constituidos por cajones. El puente pretensado más importante actualmente en Berlín es el de Disching, que salva el río Havel y cuyo objeto es el de dar paso a la carretera de la región de Spandau. Su único tramo tiene 94 m de luz y una relación entre flecha y luz de 1/63,1.

    We investigate the probability of obtaining an observable curvature perturbation, using as an example the minimal curvaton-Higgs (MCH) model. We determine &apos;probably observable&apos; and &apos;probably excluded&apos; regions of parameter space assuming generic initial conditions and applying a stochastic approach for the curvaton&apos;s evolution during inflation. Inflation is assumed to last longer than the N{sub obs}≅55 observable e-folds, and the total number of e-folds of inflation determines the particular ranges of parameters that are probable. For the MCH model, these &apos;probably observable&apos; regions always lie within the range 8 x 10{sup 4} GeV≤m{sub σ}≤2 x 10{sup 7} GeV, where m{sub σ} is the curvaton mass, and the Hubble scale at horizon exit is chosen as H{sub *}=10{sup 10} GeV. Because the &apos;probably observable&apos; region depends on the total duration of inflation, information on parameters in the Lagrangian from particle physics and from precision CMB observables can therefore provide information about the total duration of inflation, not just the last N{sub obs} e-folds. This method could also be applied to any model that contains additional scalar fields to determine the probability that these scalar fields contribute to the curvature perturbation.

  15. On the &apos;efficiency&apos; of futures markets

    1988-07-01

    One definition of market efficiency holds that today&apos;s price of an item contains all the price information that there is about that item. That is, today&apos;s price contains information about peoples&apos; expectations about the future. However, in estimating price equations analysts almost exclusively look to the past in developing price forecasting models. This paper examines the question: how do futures prices affect today&apos;s price for heating oil. That is, do futures markets add to the efficiency of markets by conveying information from the future to the present.

  16. Maintain levels of nicotine but reduce other smoke constituents: a formula for &apos;'less-hazardous'&apos; cigarettes

    Twenty-two volunteers who smoked more than 20 cigarettes with &apos;'high'&apos; nicotine yields (0.8 to 1.2 mg) per day participated in an 8-week study designed to test the hypothesis that smoking cigarettes with a constant level of nicotine but reduced deliveries of tar, carbon monoxide, and hydrogen cyanide leads to a decrease in smoke absorption. All subjects smoked their usual high-nicotine brand for the first 3 weeks (P1), and the absorption of smoke constituents was determined from levels of thiocyanate and cotinine in saliva and serum, levels of carbon monoxide in expired air, and levels of carboxyhemoglobin in the blood. During the final 5 weeks (P2), the treatment group (16 subjects) switched to the &apos;'light'&apos; version of their usual brands (similar yields of nicotine but with reduced yields of tar, carbon monoxide, and hydrogen cyanide); the control group (6 subjects) smoked their usual brands for the duration of the study. Average levels of cotinine for the subjects who switched during P2 were not significantly different from those of the control group as was expected. Slight reductions were noted in average expired-air carbon monoxide levels, blood carboxyhemoglobin, and saliva thiocyanate, but these reductions were smaller than anticipated based on brand characteristics. The results suggest that the ratio of smoke constituents is different when individuals, rather than machines, smoke cigarettes. Yields determined under subject-defined conditions are necessary in order to properly evaluate the role of nicotine in the design of &apos;'less-hazardous'&apos; cigarettes.

    It is shown that extrusion of &apos;'FORMGRIP'&apos; precursor material prior to baking leads to accelerated foaming and finer, more uniform cell structures. This effect is correlated with microstructural observations made on the precursor materials and on the foams. It is thought that, while extrusion apparently does not extensively fracture the gas-generating hydride particles, it does induce some damage to their protective surface oxide layers. Removal of the porosity normally present in as-cast precursors may also be beneficial. (Abstract Copyright [2002], Wiley Periodicals, Inc.)

    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)

  20. Macrophage-specific apoE gene repair reduces diet-induced hyperlipidemia and atherosclerosis in hypomorphic Apoe mice.

    Nathalie Gaudreault

    Full Text Available BACKGROUND: Apolipoprotein (apo E is best known for its ability to lower plasma cholesterol and protect against atherosclerosis. Although the liver is the major source of plasma apoE, extra-hepatic sources of apoE, including from macrophages, account for up to 10% of plasma apoE levels. This study examined the contribution of macrophage-derived apoE expression levels in diet-induced hyperlipidemia and atherosclerosis. METHODOLOGY/PRINCIPAL FINDINGS: Hypomorphic apoE (Apoe(h/h mice expressing wildtype mouse apoE at ∼2-5% of physiological levels in all tissues were derived by gene targeting in embryonic stem cells. Cre-mediated gene repair of the Apoe(h/h allele in Apoe(h/hLysM-Cre mice raised apoE expression levels by 26 fold in freshly isolated peritoneal macrophages, restoring it to 37% of levels seen in wildtype mice. Chow-fed Apoe(h/hLysM-Cre and Apoe(h/h mice displayed similar plasma apoE and cholesterol levels (55.53±2.90 mg/dl versus 62.70±2.77 mg/dl, n = 12. When fed a high-cholesterol diet (HCD for 16 weeks, Apoe(h/hLysM-Cre mice displayed a 3-fold increase in plasma apoE and a concomitant 32% decrease in plasma cholesterol when compared to Apoe(h/h mice (602.20±22.30 mg/dl versus 888.80±24.99 mg/dl, n = 7. On HCD, Apoe(h/hLysM-Cre mice showed increased apoE immunoreactivity in lesional macrophages and liver-associated Kupffer cells but not hepatocytes. In addition, Apoe(h/hLysM-Cre mice developed 35% less atherosclerotic lesions in the aortic root than Apoe(h/h mice (167×10(3±16×10(3 µm(2 versus 259×10(3±56×10(3 µm(2, n = 7. This difference in atherosclerosis lesions size was proportional to the observed reduction in plasma cholesterol. CONCLUSIONS/SIGNIFICANCE: Macrophage-derived apoE raises plasma apoE levels in response to diet-induced hyperlipidemia and by such reduces atherosclerosis proportionally to the extent to which it lowers plasma cholesterol levels.

  1. An Anti-apoE4 Specific Monoclonal Antibody Counteracts the Pathological Effects of apoE4 In Vivo.

    ApolipoproteinE4 (apoE4) is the most prevalent genetic risk factor for Alzheimer's disease (AD) and as such is a promising therapeutic target. This study examined the extent to which the pathological effects of apoE4 can be counteracted in vivo utilizing an immunological approach in which anti-apoE4 antibodies are applied peripherally by i.p. injections into apoE4-targeted replacement mice. Prerequisites for the successful pursuit of this objective are the availability of antibodies that specifically bind brain apoE4 and not apoE3, and demonstrating that direct application of these antibodies into the brain can counteract the effects of apoE4. Accordingly, it was shown that the antiapoE4 monoclonal antibody (mAb) 9D11 binds specifically to brain apoE4 and not apoE3. Direct i.c.v. application of mAb 9D11 prevented the apoE4-driven accumulation of Aβ in hippocampal neurons following activation of the amyloid cascade by inhibiting the Aβ-degrading enzyme neprilysin. These findings provide a proof-of-concept that anti-apoE4 mAb 9D11, when introduced into the brain, can counteract the apoE4 effects in vivo. Subsequent experiments, utilizing repeated i.p. injections of mAb 9D11, resulted in the formation of apoE/IgG complexes specifically in apoE4 mice. This was associated with reversal of the cognitive impairments of apoE4 in the Morris water maze and the novel object recognition test as well as with reversal of key apoE4-driven pathologies including the hyperphosphorylated tau and the reduced levels of the apoER2 receptor. These results indicate that anti-apoE4 immunotherapy counteracts the cognitive and brain pathological effects of apoE4, and suggest that such an approach could also benefit human apoE4 carriers.

    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.

    An hydraulic separation of a well and the cavern can be necessary for different workover applications, e.g. casing milling or underreaming. The separation is needed to ensure a mud circulation during such operations. In that case a barrier is set after flooding the cavern, which will then be used as a mechanical abutment for the cement bridge. If the diameter of the cavern neck has been enlarged due to e.g. unwanted leaching processes or unstabilized underreaming processes, it might get impossible to set a standard plug with the available technologies into those diameters. Therefore UGS GmbH has developed a mechanical plug, which is set hydraulically. The so called &apos;Spider Plug&apos; is used as basis for a cement bridge and can be removed by drilling after the workover has been done. Depending on the dimension of the setting tool a cavern neck up to 50&apos;&apos; diameter can be plugged by the &apos;Spider Plug&apos;. Up to now a number of successful operations on different locations has shown, that the &apos;Spider Plug&apos; is a practicable and cost-efficient solution for a mechanical abutment of large cavern necks.

    The purpose of this workshop was to discuss finding the object -- that is, how software engineers imagine, invent, design, or recycle objects and their behaviors for object-oriented software engineering. The workshop organizers (and, as we subsequently discovered, several of the workshop participants) felt that this issue is crucial to successful object-oriented software engineering (after all, finding objects is what the projects is all about, isn&apos;t it ). Unfortunately, when previous workshops have had the opportunity to review and discuss techniques practitioners use to find objects, too often the results were heated debates on what is an object &apos;&apos; which becomes all consuming. We believed that, given appropriate control over the question of which kind of object&apos;&apos; is being discussed (which meant tell us what object you are trying to find, then tell us your method), a workshop to concentrate on techniques for finding objects would be quite appropriate. 8 refs., 2 figs.

    Full Text Available Centenares de libros y miles de artículos han sido escritos sobre la historia de la III Internacional; no obstante en ella existen lagunas y varios enigmas. Una de las causas primordiales de este hecho es la confrontación ideológica acerca sobre la actividad del "partido comunista mundial". Porque mientras los adversarios del movimiento comunista intentaban comprobar que la actividad de las secciones nacionales de la Comintern fue dirigida siempre desde Moscú y que los partidos comunistas nunca fueron organismos independientes, los comunistas por su parte insistían en la originalidad de sus partidos y buscaban la manera de ocultar un tema muy importante, es decir, el carácter de las relaciones entre sus partidos y el Estado Mayor de la Comintern en Moscú. Ambas corrientes adversarias, al mismo tiempo basaban sus postulados sobre "las conjeturas y suposiciones" sin tener la posibilidad de comprobar sus teorías con documentos, como lo ha escrito francamente el historiador R. Alexander en su obra fundamental "Comunismo en Latinoamérica".

    This paper reviews the trends in society, technology and energy demand of the past 30 years, together with the growth of the &apos;on-demand&apos; culture. The &apos;24/7&apos; or &apos;always on&apos; society can be defined as one where people demand-and generally receive-what they want &apos;now&apos;. It has grown up in parallel with developments in information technology, which have produced the services needed to meet that demand. Larger numbers of appliances, resulting from greater affluence and disposable income, have increased energy use, despite energy efficiencies in other areas. While monetary factors suggest that changes brought about by the 24/7 society will generally be self-correcting at the macro-economic level, there will nevertheless be effects for individuals, such as potentially severe impacts on the fuel poor as electricity prices rise. We conclude with a view of future directions. As the 24/7 culture continues to grow, there is scope for designers and for information technology to manage and reduce energy consumption. This includes buildings, their services systems, and the mix of new technologies that will be deployed over the next 20 years or so, including the possibilities for data exchange and control at the interface between energy suppliers and consumers, coupled with greater understanding of the behaviour of the consumers themselves.

    A &apos;dural tail&apos; on Gd-DTPA-enhanced MRI has been often observed adjacent to meningiomas and considered to be useful in distinguishing meningioma of the cerebellopontine angle from acoustic neuroma. However, demonstration of a dural tail adjacent to an acoustic neuroma indicates that this sign is not specific. (orig.)

    The effect on radiation distribution in heterogeneous multilayer shield configurations containing cylindrical air-filled voids of different diameters have been investigated. The heterogeneous shield assemblies were placed in front of one of the horizontal channels of the ET-RR-1 reactor. The measurements of {delta}-rays and slow neutrons were carried out using LiF-7 and LiF-6 Teflon disc dosimeters, respectively. It was found that the presence of air-filled voids increases the radiation along and perpendicular to the void axis. An empirical formula has been derived to calculate the radiation distribution in the multilayer shields and a good agreement between the measured and calculated values was obtained. The formulae developed by Chase have been checked experimentally to determine the minimum amount of &apos;'patching'&apos; required on the outside of the voided shields to maintain a uniform emergent radiation distribution on the outer surface of the shielding assembly. The applicability of this formula has been defined and a semi-empirical formula developed to describe the experimental results obtained for the required &apos;'patching'&apos;. (author).

    This report is the final report of a project that the Central Bureau of Statistics of Norway has carried out. The report present analyses of the relations between economic development, energy consumption and emission of pollutants to air in a global perspective. The analyses are based on the &apos;&apos;World Model&apos;&apos;, that has been developed at the Institute for Economic Analysis at New York University. The analyses show that it will be very difficult to obtain a global stabilization of the CO[sub 2] emission on the 1990 level. In the reference scenario of the United Nations report &apos;&apos;Our Common Future&apos;&apos;, the increase of CO[sub 2] emissions from 1990 to 2020 was 73%. Even in the scenario with the most drastic measures, the emissions in 2020 will be about 43% above the 1990 level, according to the present report. A stabilization of the global emissions at the 1990 level will require strong measures beyond those assumed in the model calculations, or a considerable breakthrough in energy technology. 17 refs., 5 figs., 21 tabs.

    Administrative problems and compliance planning opportunities are the focus of this overview of the windfall profit tax on crude oil, which is actually an excise tax of a portion of domestic crude oil revenues that is tied to the removal of existing price controls on domestic crude oil. The retroactive effective date of the statute meant that the Internal Revenue Service had to draft and issue interim rules in haste, and now has to mesh the interim and final regulations with the petroleum industry&apos;s regular business practices. Producers, purchasers, and other who are affected by the tax should be alert to potential problems as well as planning opportunities that may develop during this process. The author provides a roadmap through the existing interim regulations to help interpret new changes. 204 references.

    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.)

    1985-04-01

    A calculational scheme for beat-wave accelerators is introduced that includes all orders in velocity and in plasma density, and additionally accounts for the influence of plasma nonlinearities on the wave&apos;s phase velocity. The main assumption is that the laser frequencies are very large compared to the plasma frequency - under which it is possible to sum up all orders of forward Raman scattering. It is found that the nonlinear plasma wave does not have simply a single phase velocity, but that the beat-wave which drives it is usefully described by a non-local &apos;&apos;effective phase velocity&apos;&apos; function. A time-space domain approach is followed. (LEW)

    Nonlinear special relativity (or doubly special relativity) is a simple framework for encoding properties of flat quantum spacetime. In this paper, we show how this formalism may be generalized to incorporate curvature (leading to what might be called &apos;doubly general relativity&apos;). We first propose a dual to nonlinear realization of relativity in momentum space, and show that for such a dual the spacetime invariant is an energy-dependent metric. This leads to an energy-dependent connection and curvature, and a simple modification to Einstein&apos;s equations. We then examine solutions to these equations. We find the counterpart to the cosmological metric, and show how cosmologies based upon our theory of gravity may solve the &apos;horizon problem&apos;. We discuss the Schwarzschild solution, examining the conditions for which the horizon is energy dependent. Finally, we find the weak field limit.

    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.

    Since the introduction of ionizing radiation as a treatment and diagnostic tool in humans, scientists have been trying to estimate its side effects and potential health risks. There is now ample evidence for the principal existence of a direct relationship between higher doses and the risks of side effects. Most of the uncertainties lie in the field of low-dose effects especially with respect to the risk of cancer induction. Low-dose effects are usually of relevance in diagnostic medicine while high-dose radiation effects are typically observed after radiotherapeutic treatment for cancer or after nuclear accidents. The current state of the &apos;&apos;war of theories&apos;&apos; may be summarized as follows: one group of scientists and health regulatory officials favors the hypothesis that there is no threshold dose, i.e. the linear-no-threshold hypothesis (LNT) of radiation which can be regarded as safe. On the contrary, the critics of this hypothesis suggest that the risks of doses below 50 mSv are not measurable or even of clinical relevance and are not adequately described by a linear dose-response relationship. The aim of this article is to summarize the major unresolved issues in this field. Arguments are presented why the validity of the LNT model in the low-dose range should be regarded as at least inconsistent and is thus questionable. (orig.) [German] Seit der Einfuehrung ionisierender Strahlen als ein Mittel zur Behandlung und Diagnose beim Menschen haben Wissenschaftler versucht, ihre Nebenwirkungen und potenziellen Risiken fuer die Gesundheit einzuschaetzen.

Die meisten Unsicherheiten liegen auf dem Gebiet der Niedrigdosisforschung v. a. im Hinblick auf das Risiko der Induktion von Krebs.

    A numerical method has been developed to estimate organ doses and effective dose-equivalent for patients undergoing three &apos;complex&apos; examinations (barium meal, barium enema and intravenous urography). The separation of radiological procedures into a set of standard numerical views is based on the use of Monte Carlo conversion factors and measurements within a Remab phantom. Radiation doses measured in a phantom for such examinations were compared with predictions of the &apos;'numerical'&apos; method. Dosimetric measurements with thermoluminescent dosemeters attached to the patient&apos;s skin along with measurements of the dose-area product during the examination have enabled the derivation of organ doses and to estimate effective dose-equivalent. Mean frequency weighted values of dose-area product, energy imparted to the patient, doses to a set of organs and effective dose-equivalent in the area of Madrid are reported. Comparisons of results with those from similar surveys in other countries were made. (author).

    The Konrad ore mine is a final repository for low- and intermediate-level radioactive waste in Germany. The demand for final storage suitable containers is increasing. The authors describe tests of so called &apos;'old'&apos; containers for qualification with respect to the appropriateness for final disposal. BAM (Bundesanstalt fuer Materialpruefung) has test facilities for drop tests and fire tests. The testing requirements for all available container types are discussed, including the boundary conditions with respect to the supposed waste properties, conditioning and loading. The project of container design testing is aimed to the possibility of a continuous recording of a large amount of waste packages for the final repository Konrad that allows a short-term backtracking of the relevant data for quality assurance.

    Upper Muschelkalk (Middle Triassic) carbonates produce natural gas at Coevorden field in the NE Netherlands. This is currently the only field that produces gas from this succession although several other prospects have been identified nearby. In order to help develop these hydrocarbons, this study proposes a facies and reservoir model of the Upper Muschelkalk in the NE Netherlands together with a regional framework intended to assist in further evaluation. Distribution of facies and reservoir properties of the Upper Muschelkalk carbonates in the NE Netherlands indicate deposition on a storm-dominated epeiric ramp with a very low gradient. The predominantly muddy and marly lithofacies types in proximal and distal parts of the ramp gradually interfinger with a shoreline-detached &apos;'shoal'&apos;-like ooidal grainstone complex. The best reservoir quality (permeability up to 60 mD) is recognised within dolomitised peloid ooid grainstones. These are interpreted as high-energy backshoal deposits. Reservoir quality decreases in the limestone-dominated &apos;'shoal'&apos; facies and the muddier foreshoal facies. A four-fold hierarchy of depositional cycles describes the systematic and thus predictable vertical variation in reservoir quality (permeability) and quantity (net-to-gross). High-resolution correlation suggests that medium-scale cycles (5 to 15 metres thick) can be traced for hundreds of kilometres. Small-scale cycles (1 to 3 metres thick) are persistent for several tens of kilometres and have sheet-like geometries. Individual reservoir units (several decimetres thick) appear to be laterally continuous over a maximum of a few kilometres although internal flow barriers might be expected. Mapping of Upper Muschelkalk thickness and facies has clearly defined backshoal, &apos;'shoal'&apos; and foreshoal facies belts with distinctly different reservoir characteristics. Typically, reservoir quality and quantity decrease with increasing

    The current political discussion on climate change is heavily biased towards CO{sub 2} balance, energy consumption and energy costs associated with rising energy prices. The good news is that the German Government covers sustainability in the construction sector, including - and indeed going far beyond - energy conservation. To this end the German Sustainable Building Council (DGNB) was formed in 2007, although it is worth noting that Great Britain introduced a relatively advanced sustainability assessment method referred to as BREEAM as early as 1990, an enhanced version of which was released in the USA in 1995 under the name of LEED. This article tries to show &apos;'rootstocks'&apos; for the sustainability assessment, to set up a classification system for criteria, and to derive consequences.

[German] In der derzeitigen politischen Diskussion ueber die Klimaveraenderung wird der CO{sub 2}-Bilanz und dem Energieverbrauch bzw. den mit steigenden Energiepreisen verbundenen Energiekosten eine fast ueberlastige Bedeutung beigemessen. Umso erfreulicher ist es, dass sich die Bundesregierung mit einem Leitfaden auch der Nachhaltigkeit des Bauens annimmt, welche die Energieeinsparung einschliesst, aber weit ueber diese hinausgeht, und dass sich hierzu im Jahre 2007 - wenn auch im internationalen Vergleich spaet - die Deutsche Gesellschaft fuer nachhaltiges Bauen (DGNB) gebildet hat; verspaetet deshalb, weil in Grossbritannien mit BREEAM bereits 1990 ein relativ ausgereiftes Nachhaltigkeitsbewertungsverfahren bekannt geworden war, auf das in den USA mit LEED 1995 aufgebaut wurde.

    We study a family of &apos;classical&apos; orthogonal polynomials which satisfy (apart from a three-term recurrence relation) an eigenvalue problem with a differential operator of Dunkl type. These polynomials can be obtained from the little q-Jacobi polynomials in the limit q = -1. We also show that these polynomials provide a nontrivial realization of the Askey-Wilson algebra for q = -1.

    The stability of phlogiston in eighteenth-century French chemistry depended not on its role as a comprehensive theory, but on its operational (instrumental), theoretical, and philosophical (speculative) identities that were forged in different contexts, yet were interwoven to designate a single substance. It was as &apos;real&apos; as any other chemical substance to the degree that it was obtained through material operations, occupied a place in the theoretical edifice of the affinity table, ...

  17. &apos;&apos;Life-cycle costs&apos;&apos; of industrial electric drives in the process industry - energy consumption and economics of electric drives

    For electric motors in the process industry, the purchase price is only a small fraction of the overall &apos;&apos;life-cycle costs&apos;&apos;. The most important criteria are reliability, noise and efficiency. The engineering expense for assessing energy consumption must be kept in accordance to the saving potential. In the German chemical industry, reliability has attained an encouragingly high level thanks to applying the &apos;&apos;VIK recommendations&apos;&apos;. Standardised sizes (&apos;&apos;European standard motor&apos;&apos;) guarantee the interchangeability. That gives also a good basis for introducing improved motors, e.g. with less noise or with better efficiency. Today&apos;s market offers already a high level of efficiencies: Improvements will justify only small price increases. Despite their large number, small motors of less than 1 kW consume only a small percentage of the total electricity demand in a plant, and for large motors (above 100 kW) energy losses are already evaluated in detail. For the &apos;&apos;standard motors&apos;&apos; approximately between 1 and 100 kW, a standardised classification and labelling of the motor efficiencies will be a useful tool for selecting the optimal motors for their applications. To ensure interchangeability, the motor sizes and installation dimensions must remain unchanged. (orig.)

    The concept of &apos;green&apos; chemotherapy by employing targeted nanoparticle mediated delivery to enhance the efficacy of phytomedicines is reported. Poly (lactide-co-glycolide) (PLGA) nanoparticles encapsulating a well known nutraceutical namely, grape seed extract (GSE)-&apos;NanoGSE&apos;-was prepared by a nanoprecipitation technique. The drug-loaded nanoparticles of size {approx} 100 nm exhibited high colloidal stability at physiological pH. Molecular receptor targeting of this nanophytomedicine against folate receptor over-expressing cancers was demonstrated in vitro by conjugation with a potential cancer targeting ligand, folic acid (FA). Fluorescence microscopy and flow cytometry data showed highly specific cellular uptake of FA conjugated NanoGSE on folate receptor positive cancer cells. Studies were also conducted to investigate the efficiency of targeted (FA conjugated) versus non-targeted (non-FA conjugated) nanoformulations in causing cancer cell death. The IC{sub 50} values were lowered by a factor of {approx} 3 for FA-NanoGSE compared to the free drug, indicating substantially enhanced bioavailability to the tumor cells, sparing the normal ones. Receptor targeting of FA-NanoGSE resulted in a significant increase in apoptotic index, which was also quantified by flow cytometry and fluorescence microscopy. This in vitro study provides a basis for the use of nanoparticle mediated delivery of anticancer nutraceuticals to enhance bioavailability and effectively target cancer by a &apos;green&apos; approach.

    Ran Antes

    Full Text Available The vertebrate retina, which is part of the central nervous system, is a window into the brain. The present study investigated the extent to which the retina can be used as a model for studying the pathological effects of apolipoprotein E4 (apoE4, the most prevalent genetic risk factor for Alzheimer's disease (AD. Immunohistochemical studies of retinas from young (4 months old apoE4-targeted replacement mice and from corresponding mice which express the AD benign apoE3 allele, revealed that the density of the perikarya of the different classes of retinal neurons was not affected by apoE4. In contrast, the synaptic density of the retinal synaptic layers, which was assessed immunohistochemically and by immunoblot experiments, was significantly lower in the apoE4 than in the apoE3 mice. This was associated with reduced levels of the presynaptic vesicular glutamatergic transporter, VGluT1, but not of either the GABAergic vesicular transporter, VGaT, or the cholinergic vesicular transporter, VAChT, suggesting that the glutamatergic nerve terminals are preferentially affected by apoE4. In contrast, the post synaptic scaffold proteins PSD-95 and Gephyrin, which reside in excitatory and inhibitory synapses, respectively, were both elevated, and their ratio was not affected by apoE4. Electroretinogram (ERG recordings revealed significant attenuation of mixed rod-cone responses in dark-adapted eyes of apoE4 mice. These findings suggest that the reduced ERG response in the apoE4 mice may be related to the observed decrease in the retinal nerve terminals and that the retina could be used as a novel model for non-invasive monitoring of the effects of apoE4 on the CNS.

  20. Postprandial apoE isoform and conformational changes associated with VLDL lipolysis products modulate monocyte inflammation.

    Laura J den Hartigh

    Full Text Available Postprandial hyperlipemia, characterized by increased circulating very low-density lipoproteins (VLDL and circulating lipopolysaccharide (LPS, has been proposed as a mechanism of vascular injury. Our goal was to examine the interactions between postprandial lipoproteins, LPS, and apoE3 and apoE4 on monocyte activation.We showed that apoE3 complexed to phospholipid vesicles attenuates LPS-induced THP-1 monocyte cytokine expression, while apoE4 increases expression. ELISA revealed that apoE3 binds to LPS with higher affinity than apoE4. Electron paramagnetic resonance (EPR spectroscopy of site-directed spin labels placed on specific amino acids of apoE3 showed that LPS interferes with conformational changes normally associated with lipid binding. Specifically, compared to apoE4, apoE bearing the E3-like R112→Ser mutation displays increased self association when exposed to LPS, consistent with a stronger apoE3-LPS interaction. Additionally, lipolysis of fasting VLDL from normal human donors attenuated LPS-induced TNFα secretion from monocytes to a greater extent than postprandial VLDL, an effect partially reversed by blocking apoE. This effect was reproduced using fasting VLDL lipolysis products from e3/e3 donors, but not from e4/e4 subjects, suggesting that apoE3 on fasting VLDL prevents LPS-induced inflammation more readily than apoE4.Postprandial apoE isoform and conformational changes associated with VLDL dramatically modulate vascular inflammation.

    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.

    &apos;'Recycled'&apos; millisecond pulsars are a variety of rapidly spinning neutron stars that typically show thermal X-ray radiation due to the heated surface of their magnetic polar caps. Detailed numerical modeling of the rotation-induced thermal X-ray pulsations observed from recycled millisecond pulsars, including all relevant relativistic and stellar atmospheric effects, has been identified as a promising approach towards an astrophysical determination of the true neutron star mass-radius relation, and by extension the state of cold matter at densities exceeding those of atomic nuclei. Herein, I review the basic model and methodology commonly used to extract information regarding neutron star structure from the pulsed X-ray radiation observed from millisecond pulsars. I also summarize the results of past X-ray observations of these objects and the prospects for precision neutron star mass-radius measurements with the upcoming Neutron Star Interior Composition Explorer (NICER) X-ray timing mission.

    A divergence-free, parameter-free, path-based discrete-time quantum dynamics is designed to not only enlarge the achievements of general relativity and the standard particle model, by approximations at spacetime scales far above Planck scale while far below Hubble scale, but to allow tackling of hitherto inaccessible questions. &apos;&apos;Path space&apos;&apos; is larger than and precursor to Hilbert-space basis. The wave-function-propagating paths are action-carrying structured graphs-cubic and quartic structured vertices connected by structured &apos;'fermionic'&apos; or &apos;'bosonic'&apos; &apos;'particle'&apos; and &apos;'nonparticle'&apos; arcs. A Planck-scale path step determines the gravitational constant while controlling all graph structure. The basis of the theory&apos;s (zero-rest-mass) elementary-particle Hilbert space (which includes neither gravitons nor scalar bosons) resides in particle arcs. Nonparticle arcs within a path are responsible for energy and rest mass.

    Apolipoprotein E4 (ApoE4), the most prevalent genetic risk factor for Alzheimer's disease (AD), is associated with increased neurodegeneration and vascular impairments. Vascular endothelial growth factor (VEGF), originally described as a key angiogenic factor, has recently been shown to play a crucial role in the nervous system. The objective of this research is to examine the role of VEGF in mediating the apoE4-driven pathologies. We show that hippocampal VEGF levels are lower in apoE4 targeted replacement mice compared to the corresponding apoE3 mice. This effect was accompanied by a specific decrease in both VEGF receptor-2 and HIF1-α. We next set to examine whether upregulation of VEGF can reverse apoE4-driven pathologies, namely the accumulation of hyperphosphorylated tau (AT8) and Aβ42, and reduced levels of the pre-synaptic marker, VGluT1, and of the ApoE receptor, ApoER2. This was first performed utilizing intra-hippocampal injection of VEGF-expressing-lentivirus (LV-VEGF). This revealed that LV-VEGF treatment reversed the apoE4-driven cognitive deficits and synaptic pathologies. The levels of Aβ42 and AT8, however, were increased in apoE3 mice, masking any potential effects of this treatment on the apoE4 mice. Follow-up experiments utilizing VEGF-expressing adeno-associated-virus (AAV-VEGF), which expresses VEGF specifically under the GFAP astrocytic promoter, prevented this effects on apoE3 mice, and reversed the apoE4-related increase in Aβ42 and AT8. Taken together, these results suggest that apoE4-driven pathologies are mediated by a VEGF-dependent pathway, resulting in cognitive impairments and brain pathology. These animal model findings suggest that the VEGF system is a promising target for the treatment of apoE4 carriers in AD.

  13. What does the APO mean?

    Yafei Wang

    2016-10-01

    Full Text Available The Asian–Pacific Oscillation (APO is a relatively new teleconnection index and a number of peer-reviewed studies have confirmed its’ existence. This study reexamines the concept of the APO teleconnection as currently published in the literature. Most results have found that this pattern could be defined as its own teleconnection pattern within the Pacific Ocean Basin. This work demonstrates that the APO is inevitably associated with an additional action centre located over the North Atlantic Ocean, and the index can be extended. Previous studies have used a variety of methods to represent the APO, and a method is proposed here to standardise the formulation. It is argued that the extended index proposed here provides a more robust result. The APO typically is identified using the eddy temperature rather than geopotential height as the source material for its construction, as geopotential could not adequately represent this teleconnection pattern. This leads to a discussion regarding the basic criterion for defining teleconnective activity within the extratropical regions. We also identify other problems in the current understanding of APO theory that need to be addressed.

    &apos;'smesh'&apos; is a general purpose, interactive, 2D unstructured mesh generator based on Overture. It supports three kinds of mesh generation techniques: structured patches with transfinite interpolation (TFI); unstructured triangles based on an advancing front technique; and a Cartesian cutcell/triangle hybrid method. Meshes are generated in a generalized &apos;'multi-block'&apos; manner where each &apos;'block'&apos;, or region, can be one of the three mesh types. Geometry definitions can be created interactively by placing points and interpolating curves. Spacing information is provided by both the curve discretization (which can be stretched) and a user specified preferred grid spacing for a region. A mesh optimization procedure is available for the non-TFI regions for mesh quality improvement. Each mesh region is given an unique identifier and an optional string name. Meshes are exported to a modified &apos;'ingrid'&apos; format including mesh region identifiers and names. Facilities for command scripting and batch running are available.

    The performance of the novel &apos;'ductless'&apos; personalized ventilation in conjunction with displacement ventilation (DV) was compared with the performance of DV alone under realistic conditions involving disturbances due to walking of one or two persons. An office room with two workstations was arranged in a full-scale test room. Two thermal manikins were used as sedentary occupants at the workstations. Two pollution sources, namely exhaled air by one of the manikins and passive pollution on the table in front of the same manikin were simulated. The performance of the ventilation systems was evaluated with regard to the quality of inhaled air and thermal comfort of the seated &apos;'occupants'&apos;. The walking person(s) caused mixing of the clean and cool air near the floor with the polluted and warmer air at higher levels and disturbed the displacement principle which resulted in a decrease of the inhaled air quality. The performance of the &apos;'ductless'&apos; PV under the tested conditions was better as opposed to DV alone. Thus in practice the &apos;'ductless'&apos; PV will be superior to DV alone as regards perceived quality of inhaled air. The location of a walking person was found to be important. Person(s) walking close to the displacement diffuser will cause greater disturbance. (author)

    2006-10-01

    Full Text Available Abstract More than a decade has passed since apolipoprotein E4 (APOE-ε4 was identified as a primary risk factor for Alzheimer 's disease (AD, yet researchers are even now struggling to understand how the apolipoprotein system integrates into the puzzle of AD etiology. The specific pathological actions of apoE4, methods of modulating apolipoprotein E4-associated risk, and possible roles of apoE in normal synaptic function are still being debated. These critical questions will never be fully answered without a complete understanding of the life cycle of the apolipoprotein receptors that mediate the uptake, signaling, and degradation of apoE. The present review will focus on apoE receptors as modulators of apoE actions and, in particular, explore the functions of soluble apoE receptors, a field almost entirely overlooked until now.

    Full Text Available In 1353, the judge of Arborea, the most powerful ally and vassal of king Peter "the Ceremonious" in Sardinia, rose up and attacked the king’s territories in the island, cooperating with rebels and enemies of the king, such as Genoa, Milan and the Doria family. In 1354, Peter “the Ceremonious”, king of Aragon, led a powerful army to Sardinia, intending to fight his enemies in their territories. The 1354 campaign was carefully planned, but the resistance of the city of Alghero stopped the royal army and fleet operations, challenging a logistical system unable to support such a huge and unsupplied military expedition. This paper demonstrates the way geostrategic, political, operational and logistical realities were closely linked to configure the profile of a powerful military campaign, and how these realities can be useful to understand broader military, political and historical changes.

    En 1353 el juez de Arborea, el más poderoso aliado y vasallo de Pedro el Ceremonioso en Cerdeña, se rebeló y atacó los territorios regios de la isla, cooperando con rebeldes y enemigos del rey como Génova, Milán y la familia de los Doria. En 1354 Pedro el Ceremonioso, rey de Aragón, comandó una potente armada a la isla tratando de combatir a sus enemigos en su territorio. La campaña de 1354 fue cuidadosamente planeada, pero la resistencia de la ciudad de Alguer detuvo las operaciones de la flota y el ejército regios, poniendo a prueba un sistema logístico incapaz de apoyar una expedición tan grande y falta de suministros. Este trabajo expone cómo las realidades geoestratégicas, políticas, operacionales y logísticas estuvieron estrechamente relacionadas para configurar el perfil de una potente campaña militar, y cómo dichas realidades pueden servir para entender cambios militares, políticos e históricos de mayor alcance y duración.

  19. The synchro crusher: a new type of impact?; Le &apos;'synchro-concasseur'&apos;: du nouveau dans l&apos;impact?

    The seminar organized by &apos;Quarry Management&apos; on the occasion of the Hillhead 99 workshop provided the Dutch company VanderZanden with the opportunity to present its research work on the development of a new concept of crushing called &apos;SynchroCrusher&apos;. Its principle uses the &apos;relative movement&apos; linked with &apos;synchronization&apos;. Each particle is uniformly and precisely crushed by a double impact, the second impact being only generated by the residual (free) energy and occurring at a greater speed. An optimal direct impact is obtained thanks to a perfect control of the impact angle (between 75 and 85 deg.) and of the particle trajectories with no interference between particles. This system allows to reduce both the energy consumption and the wear of crushers. This paper presents the concept of the SynchroCrusher, its comparison with other classical impact crushers and the R and D work carried out to analyze the movement of particles, the capacity of the crusher with respect to the orientation of blades, the directional changes of particles inside the crusher and the synchronization of particle trajectories.

    The human APOE4 allele is associated with an early age of onset and increased risk of Alzheimer's disease (AD). Apolipoprotein E is secreted as part of a high-density lipoprotein-like particle by glial cells in the brain for the primary purpose of transport of lipophilic compounds involved in the maintenance of synapses. Previous studies examining synaptic integrity in the amygdala of human apoE targeted replacement (TR) mice showed a decrease in spontaneous excitatory synaptic activity, dendritic arbor, and spine density associated with apoE4 compared with apoE3 and apoE2 in adult male mice. In the present study, we assessed how APOE genotype affects synaptic integrity of amygdala neurons by comparing electrophysiological and morphometric properties in human apoE3, E4, and E2/4 TR mice at the age of 18-20 months. In contrast to adult mice, we found that aged apoE4 TR mice exhibited the highest level of excitatory synaptic activity compared with other cohorts. Additionally, apoE4 mice had significantly greater spontaneous inhibitory activity than all other cohorts. Taken together, there was a significant interaction between genotypes when comparing inhibition relative to excitation; there was a simple main effect of frequency type with an imbalance toward inhibition in apoE4 mice but not in apoE3 or apoE2/4 mice. These results suggest that apoE isoforms differentially influence synaptic transmission throughout the life span, where aging coupled with apoE4 expression, results in an imbalance in maintaining integrity of synaptic transmission.

  1. Why Germany&apos;s &apos;Messy&apos; energy transition should be a lesson to other nations

    Germany&apos;s so-called &apos;&apos;energy transition&apos;&apos; (&apos;'Energiewende'&apos;) is increasingly drawing the intention of the international community - but it seems for all the wrong reasons. US Senator Lamar Alexander said recently that German energy policy is one of the reasons the US should not abandon nuclear, but actually encourage increased investment in nuclear power plants. Alexander&apos;s remarks were made in an article published by the US Nuclear Energy Institute, in which he outlined his reasons why the US should not follow Germany&apos;s lead. Alexander rightly pointed out that the cost of attempting to replace nuclear power with wind, solar, and accompanying infrastructure is estimated by the German government at some 1.2 trillion US dollars (about 1 trillion Euros). The senator also made the point that Germany &apos;&apos;does not produce enough reliable, baseload energy for an important manufacturing economy&apos;&apos;. He also expressed concern at Germany&apos;s reliance on buying natural gas from Russia. While Germany has been forcing the closure of nuclear power plants others, including the oil-rich United Arab Emirates (UAE), have been investing in new nuclear, Alexander said. Judging from Alexander&apos;s remarks, it seems that Germany&apos;s energy transition experience will, after all, have a long-lasting legacy. That legacy will be a valuable lesson to other major industrialised nations in why they should not follow Germany&apos;s lead in abandoning a sensible energy mix, if they wish to maintain and develop economic and industrial productivity while keeping to international commitments to tackle climate change.

    The authors continue the series of papers describing the results of a photometric survey of open star clusters, primarily in the southern hemisphere, taken in the u&apos;g'r'i'z&apos; filter system. The entire observed sample covered more than 100 clusters, but here they present data only on NGC 188, which is one of the oldest open clusters known in the Milky Way. They fit the Padova theoretical isochrones to the data. Assuming a solar metallicity for NGC 188, they find a distance of 1700 {+-} 100 pc, an age of 7.5 {+-} 0.7 Gyr, and a reddening E(B-V) of 0.025 {+-} 0.005. This yields a distance modulus of 11.23 {+-} 0.14.

  3. Energy and the new class. [Assault of &apos;&apos;new breed&apos;&apos; of American on established institutions

    The bounty of the US is taken for granted by its population. Nowhere is this misvaluation of a society and its benefits more evident than in the energy industries. 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.

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

    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.

    This paper introduces the world&apos;s first indoor snow-fall type artificial ski facility &apos;SSAWS&apos;. Skiing can be enjoyed throughout a year by virtue of artificial snow making machines. Snow quality control requires that the temperature in the ski slope be kept below the freezing point at all times. Means to achieve the requirement included reducing outer wall load by using heat insulation, recovering waste heat from the ski slope by using heat pipes, preventing cold air from leaking and outside air from entering, and adopting a cogeneration system. The cold heat source is a warm water absorbing freezer utilizing waste heat from a gas engine for the cogeneration. The cogeneration system has saved more than 60% of the air conditioning and hot water supplying energy, reducing the annual expense by 15%. The snow making system has a nozzle jet out very highly homogeneous and microfine water droplets with compressed air, and freeze them at -5[degree]C utilizing adiabatic expansion into snow to fall on the slope. The system can control the snow quality as required. The floor of the ski slope is in contact with atmosphere, where snow melting progresses from the lower part as a result of temperature gradient. Therefore, neither special heat source is required, nor a work to scrape and remove the snow that has been stained. 4 refs., 11 figs.

    &apos;Biomoleculas&apos; is a software that deals with topics such as the digestion, cellular metabolism and excretion of nutrients. It is a pleasant, simple and didactic guide, made by and for students. In this program, each biomolecule (carbohydrates, lipids and proteins) is accompanied until its degradation and assimilation by crossing and interrelating the different metabolic channels to finally show the destination of the different metabolites formed and the way in which these are excreted. It is used at present as a teaching-learning process tool by the chair of Physiology and Biophysics at the Facultad de Ingenieria - Universidad Nacional de Entre Rios.

    A classical logic exhibits a threefold inner structure comprising an algebra of propositions U, a space of &apos;truth values&apos; V, and a distinguished family of mappings {phi} from propositions to truth values. Classically U is a Boolean algebra, V = Z{sub 2}, and the admissible maps {phi}: U Z{sub 2} are homomorphisms. If one admits a larger set of maps, one obtains an anhomomorphic logic that seems better suited to quantal reality (and the needs of quantum gravity). I explain these ideas and illustrate them with three simple examples.

    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

    Children suffering from Gaucher&apos;s disease were examined by magnetic resonance imaging (MRI) during a characteristic episode of &apos;bone crisis&apos;. An unexpectedly high intramedullary as well as subperiosteal signal was observed on both the T1- and T2-weighted sequences in 5 patients, suggesting a subacute hemorrhage or hematoma. It is conceivable that such a painful hemorrhage is an important component of the &apos;bone crisis&apos; phenomenon. Furthermore, in these cases this is a specific sign which may enable differentiation of bone crises from other types of bone pain associated with Gaucher&apos;s disease. (orig.).

    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.

    This paper investigates rationale explanations of OPEC&apos;s strategies. Accounting for market characteristics in particular the sluggishness of demand and supply allows to explain price jumps as rational OPEC strategies from a narrow economic perspective (up and down) as well as from political objectives (at least up) due to the political payoff from standing up against the &apos;West&apos;. Although the temptation to accrue this political payoff was and remains high, the narrow economic profit motive coupled with an imperfect cooperation among OPEC members explains past price volatility and high prices much better than the usual reference to political events. A more specific prediction is that OPEC will switch back to setting prices since the current quantity strategy encourages oil importing countries to appropriate rents in particular in connection with the need to mitigate global warming.

    The ongoing liberalisation of European gas markets forces network operators as well as retail companies to implement new processes. This article focuses on the challenges for network operators. In this context the potential for &apos;Neutral Service Providers (NSP)&apos; is discussed. Based on sample TPA processes the interaction between the NSP and the network operator is explored. The authors conclude that for many market participants the outsourcing of TPA processes to a specialized service provider has the potential to deliver significant benefits. (orig.) [German] Die fortschreitende Liberalisierung der europaeischen Erdgasmaerkte stellt die Netz- sowie die Vertriebsgesellschaften vor staendig wachsende Anforderungen.

In diesem Zusammenhang werden die hieraus resultierenden Marktchancen fuer neue Dienstleistungsunternehmen, die sogenannten &apos;Neutral Service Provider&apos; (NSP) eroertert. Anhand eines Prozessbeispiels wird die Interaktion zwischen NSP und den von ihm betreuten Netzbetreibern diskutiert. Die Autoren kommen zu dem Schluss, dass fuer viele Marktteilnehmer die Auslagerung bestimmter Unternehmensaktivitaeten im Zusammenhang mit der Bewaeltigung des Netzzugangs Dritter an einen spezialisierten Dienstleister mit erheblichen Vorteilen verbunden ist.

    In the present work the massless vector field in the de Sitter (dS) space has been quantized. &apos;Massless&apos; is used here by reference to conformal invariance and propagation on the dS light-cone whereas &apos;massive&apos; refers to those dS fields which contract at zero curvature unambiguously to massive fields in Minkowski space. Due to the gauge invariance of the massless vector field, its covariant quantization requires an indecomposable representation of the de Sitter group and an indefinite metric quantization. We will work with a specific gauge fixing which leads to the simplest one among all possible related Gupta-Bleuler structures. The field operator will be defined with the help of coordinate independent de Sitter waves (the modes) which are simple to manipulate and most adapted to group theoretical matters. The physical states characterized by the divergence-lessness condition will for instance be easy to identify. The whole construction is based on analyticity requirements in the complexified pseudo-Riemannian manifold for the modes and the two-point function. (authors)

    Full Text Available Abstract Background Apolipoprotein E (apoE is postulated to affect brain Aβ levels through multiple mechanisms--by altering amyloid precursor protein (APP processing, Aβ degradation, and Aβ clearance. We previously showed that an apoE-derived peptide containing a double repeat of the receptor-binding region was similarly effective in increasing APP processing in vivo. Here, we further examined whether peptides containing tandem repeats of the apoE receptor-binding region (amino acids 141-149 affected APP trafficking, APP processing, and Aβ production. Results We found that peptides containing a double or triple tandem repeat of the apoE receptor-binding region, LRKLRKRLL, increased cell surface APP and decreased Aβ levels in PS1-overexpressing PS70 cells and in primary neurons. This effect was potentiated by a sequential increase in the number of apoE receptor-binding domain repeats (trimer > dimer > monomer. We previously showed that the apoE dimer increased APP CTF in vivo; to determine whether the dimer also affected secreted APP or Aβ levels, we performed a single hippocampal injection of the apoE dimer in wild-type mice and analyzed its effect on APP processing. We found increased sAPPα and decreased Aβ levels at 24 hrs after treatment, suggesting that the apoE dimer may increase α-secretase cleavage. Conclusions These data suggest that small peptides consisting of tandem repeats of the apoE receptor-binding region are sufficient to alter APP trafficking and processing. The potency of these peptides increased with increasing repeats of the receptor binding domain of apoE. In addition, in vivo administration of the apoE peptide (dimer increased sAPPα and decreased Aβ levels in wild-type mice. Overall, these findings contribute to our understanding of the effects of apoE on APP processing and Aβ production both in vitro and in vivo.

    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.)

    Using conventional programming techniques for the production of data acquisition and control software can be a time-consuming procedure, and the code subsequently produced can often be inflexible and rather difficult to modify in the light of changing experimental requirements. A new generation of commercial software products have recently appeared which it is claimed can significantly reduce development times and give rise to more flexible code and improved user interfaces. An example of such a product is National Instruments&apos; LabVIEW,&apos;&apos; which presents a novel graphical approach based on Apple Macintosh computer platforms. Extensive use of LabVIEW has been made by the Soft X-ray Group at Daresbury Laboratory over the past two years, and its performance is reported on here. Several examples of experimental arrangements for which it has been used are described, and an evaluation of the product is made.

    Experimental results of the aerosol size distribution inside the Object &apos;'Shelter'&apos; are evaluated in the work. The results show a consistent and significant contribution of sub-micron fraction to the total aerosol activity. Different methods of interpretation of impactor data series are evaluated in terms of adequate assessment of the separate sub-micron aerosol fraction. The contribution of the sub-micron component to the total aerosol activity was found to be about 35%. Results of this research were also compared to those of other authors conducted with by using identical impactor equipment, e.g. results of aerosol sampling at a Czech NPP Dukovany. It is demonstrated in the work that observation of such a significant contribution of the sub-micron fraction for the Shelter aerosol can be hardly explained by systematic failure of the sampling equipment. Also physical mechanisms and corresponding observations of sub-micron aerosol generation inside the Shelter as well as subsequent dosimetric aspects are discussed. (orig.)

    The proposed research aims to develop a fundamental understanding of important biological and physical chemical parameters for effective decontamination of metal surfaces using environmentally benign aqueous-based biopolymer solutions. Understanding how heavy metal-chelating biopolymers coat and interact with contaminated surfaces will benefit the development of novel, safe, easy-to-apply decontamination methodologies for removal of radionuclides and heavy metals. The benefits of these methodologies will include the following: (1) decreased exposure hazards for workers; (2) decreased secondary waste generation; (3) increased efficiency of decontamination; (4) positive public appeal and development of novel, nature-friendly business opportunities; and (5) lower cost of cleanup to the government. We propose to use aqueous biopolymer solutions to coat a contaminated metal surface (i.e., steel), solubilize the heavy metals (e.g., uranium) from the surface, and bind the heavy metals into the biopolymer. The biopolymer coating (containing the immobilized hazardous metal contaminants) will then be removed as a viscous film, as a dry powder, or by washing. This &apos;&apos;apply, wait, and remove&apos;&apos; procedure will reduce the amount of worker time spent in decontamination activities.

    Abusive head trauma (AHT) in infants is usually diagnosed using a multi-disciplinary approach by investigating the circumstances and identifying morphological indicators, for example, subdural hematomas (SDHs), subdural hygromas (SDHys), retinal haemorrhages and encephalopathy. The present morphological study investigates the incidence, radiological characteristics and non-radiological co-factors of bridging vein thrombosis (BVT) in infants with AHT. From 2002 to 2013, computed tomography (CT) and magnetic resonance imaging (MRI) material of 628 infants aged 0-2 years were analysed retrospectively. If available, medicolegal expert opinions were additionally considered. Cases with SDHs and/or SDHys were identified and systematically evaluated as to the presence and characteristics of BVT. SDHs and/or SDHys were present in 29 of the 81 cases exhibiting morphological abnormalities in the initial CT. Among these, 11 cases (40 %) had BVT (mean age = 5.0 months). BVT could be best depicted in the T1-weighted spin echo and T2*/susceptibility-weighted MRI. In one case, BVT could be depicted indirectly using time-of-flight MR venography. The predominant (73 %) BVT shape was found to be tadpole-like (&apos;&apos;Tadpole Sign&apos;&apos;). In the absence of appropriate accidental trauma, BVT appears to be a strong indicator of AHT. Therefore, the BVT/Tadpole Sign represents compelling cause to search for other signs of AHT. (orig.)

    This project had two main objectives. The first major goal was to develop new, powerful computational simulation capabilities. It was important that these tools have the combination of the accuracy needed to describe the quantum mechanical nature of nanoscale systems and the efficiency required to be applied to realistic, experimentally derived materials. The second major goal was to apply these computational methods to calculate and predict the properties of quantum dots--initially composed of silicon, but then of other elements--which could be used to build novel nanotechnology devices. The driving factor of our purpose has been that, through the development and successful application of these tools, we would generate a new capability at LLNL that could be used to make nanostructured materials &apos;'smarter'&apos;, e.g., by selectively predicting how to engineering specific, desired properties. To carry out the necessary work to successfully complete this project and deliver on our goals, we established a two-pronged effort from the beginning: (1) to work on developing new, more efficient algorithms and quantum simulation tools, and (2) to solve problems and make predictions regarding properties of quantum dots which were being studied experimentally here at Livermore.

    We report on the first successfull application of a new experimental technique to search for weakly interacting sub-eV particles (WISPs) coupling to photons. As part of the ALPS experiment located at DESY in Hamburg, this technique uses an optical resonator to enhance the power inside a HERA dipole magnet on the production side of a typical &apos;&apos;light shining through a wall&apos;&apos;-experiment. We use a frequency doubled continuous-wave laser emitting 0.6 W of power at 532 nm that is stabilized to a linear optical resonator with 8 m length. On resonance we achieve a circulating power of 34 W within the magnet. With this we obtained sensitivities corresponding to a coupling strength of g{approx}5.10{sup -7} GeV{sup -1} for interactions of axion-like particles and photons. The experimental setup and possible improvements are described and compared with common experimental designs with pulsed lasers.

    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.

    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.

    A potentiometric sensor based on the 1-benzyl-3-(4-nitrophenyl) thio-urea was synthesized and tested as an ionophore in PVC based membrane sensor towards SCN - ions. This membrane exhibits a linear stable response over a wide concentration range (1.0 × 10&apos;&apos;-5 to 1.0 × 10&apos;&apos;-2 M) with a slope of -59.2 mV/dec., a detection limit of log[SCN&apos;&apos;- ] = -5.05, and a selectivity coefficient for thiocyanate against perchlorate anion of logK{sub s}cn&apos;&apos;pot = -0.133. The selectivity series of the membrane is as follows: SCN&apos;&apos;- > ClO{sub 4}&apos;&apos;- > I&apos;&apos;- >NO{sub 3}&apos;&apos;- >HSO{sub 3}&apos;&apos;- > Cl&apos;&apos;-HSO{sub &apos;}'-'&apos;4 > F&apos;&apos;- > CH{sub 3}COO&apos;&apos;- > HCO&apos;'-'&apos;3 > Br&apos;&apos;- > H{sub 2}PO{sub 4}&apos;&apos;- > SO{sub 3}&apos;'-'&apos;2 > SO{sub 4}&apos;'-'&apos;2 > CO{sub 3}&apos;'-'&apos;2. The proposed electrode showed good selectivity and a good response for the SCN&apos;&apos;- ion over a wide variety of other anions in pH 6.0 buffer solutions and has a fast response time of about < 5s.. The influences of the membrane by pH, ionophore, and plasticizer were studied.

  6. Introducing Human APOE into Aβ Transgenic Mouse Models

    Full Text Available Apolipoprotein E (apoE and apoE/amyloid-β (Aβ transgenic (Tg mouse models are critical to understanding apoE-isoform effects on Alzheimer's disease risk. Compared to wild type, apoE−/− mice exhibit neuronal deficits, similar to apoE4-Tg compared to apoE3-Tg mice, providing a model for Aβ-independent apoE effects on neurodegeneration. To determine the effects of apoE on Aβ-induced neuropathology, apoE−/− mice were crossed with Aβ-Tg mice, resulting in a significant delay in plaque deposition. Surprisingly, crossing human-apoE-Tg mice with apoE−/−/Aβ-Tg mice further delayed plaque deposition, which eventually developed in apoE4/Aβ-Tg mice prior to apoE3/Aβ-Tg. One approach to address hAPOE-induced temporal delay in Aβ pathology is an additional insult, like head injury. Another is crossing human-apoE-Tg mice with Aβ-Tg mice that have rapid-onset Aβ pathology. For example, because 5xFAD mice develop plaques by 2 months, the prediction is that human-apoE/5xFAD-Tg mice develop plaques around 6 months and 12 months before other human-apoE/Aβ-Tg mice. Thus, tractable models for human-apoE/Aβ-Tg mice continue to evolve.

    Objectives: Since the first description of rapid destruction of dental hard tissues following head and neck radiotherapy 80 years ago, &apos;radiation caries&apos; is an established clinical finding. The internationally accepted clinical evaluation score RTOG/EORTC however is lacking a classification of this frequent radiogenic alteration. Material and Methods: Medical records, data and images of radiation effects on the teeth of more than 1,500 patients, who underwent periradiotherapeutic care, were analyzed. Macroscopic alterations regarding the grade of late lesions of tooth crowns were used for a classification into 4 grades according to the RTOG/EORTC guidelines. Results: No early radiation effects were found by macroscopic inspection. In the first 90 days following radiotherapy 1/3 of the patients complained of reversible hypersensitivity, which may be related to a temporary hyperemia of the pulp. It was possible to classify radiation caries as a late radiation effect on a graded scale as known from RTOG/EORTC for other organ systems. This is a prerequisite for the integration of radiation caries into the international nomenclature of the RTOG/EORTC classification. Conclusions: The documentation of early radiation effects on dental hard tissues seems to be neglectable. On the other hand the documentation of late radiation effects has a high clinical impact. The identification of an initial lesion at the high-risk areas of the neck and incisal part of the tooth can lead to a successful therapy as a major prerequisite for orofacial rehabilitation. An internationally standardized documentation is a basis for the evaluation of the side effects of radiooncotic therapy as well as the effectiveness of protective and supportive procedures. (orig.)

    During the previous six annual sessions of the International Petroleum Environmental Conference (IPEC), little attention has been given to international issues. Although the US is clearly a leader in oil field research and regulatory development information is available on interesting projects throughout the world Many participants in IPEC have little exposure to international oil and gas environmental problems and solutions. Beginning with the 7th IPEC, a stronger effort is being made to include international issues in the confidence. This paper describes some of the author&apos;s experiences in working with international oil and gas environmental issues in North America, Latin America, Europe, and Asia. Among the topics to be discussed are the issues that developing oil and gas-producing nations face and the need for sensitivity to other nation&apos;s cultures and legal systems.

    In 2004 the Matra plant management initiated a 60 M euro investment programme to increase the generating capacity of units 4 and 5 of the lignite fuelled plant and to give it greater flexibility. This has been achieved by adding a 30 MW natural gas-fired topping gas turbine to each of the 230 MW units, for commissioning by 2007. The power uprate meant the capacity of the dry-tower based cooling system was increased by 24 W for each unit. This has now undergone a major upgrade, involving addition of a wet cooling tower to create a &apos;hybrid&apos; system. It is one of the largest such projects ever carried out, and the first involving a dry-tower cooling system of the Heller type. The result is increased competitiveness and efficiency, with a 250,000 t reduction in annual carbon dioxide emissions. 3 figs.

    Results: The SBP and DBP were significantly high between 3 groups. The mean plasma TC, TGL, VLDL, LDL, MDA, ApoB levels, ApoB/ApoA-I were significantly high and HDL, ApoA-I, NO, FRAP levels were significantly low between 3 groups. The ApoB/ApoA-I was positively correlated with TC, TGL, VLDL, LDL, malondialdehyde and negatively correlated with HDL, FRAP and NO. Conclusions: Our results indicate that women with PE and E exhibit markedly elevated concentrations of TGL-rich lipoproteins. The negative correlation between ApoB/ApoA-I with NO indicates that the hyperlipidemia is directly related with severity of ED in PIH. So, careful monitoring of ApoB/ApoA-I along with NO might be helpful to predict the onset and progression of the disease. [Int J Res Med Sci 2016; 4(5.000: 1329-1334

    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.

    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.

    Full Text Available La contaminación en los ríos de Costa Rica es un problema que merece especial atención. El concepto “contaminación del agua” implica la incorporación de materias extrañas a esta, tales como microorganis- mos (coliformes totales y fecales, productos quími- cos (jabones, fer tilizantes, pesticidas, metales pesados (cromo, plomo, mercurio, etc. o materia orgánica proveniente de los suelos a través de la escorrentía superficial y de las aguas residuales domésticas. Estas materias deterioran la calidad del agua y reducen los diferentes usos que podría tener un río. El recurso hídrico es importante tanto para la preservación de la vida humana como para la conservación de la flora y fauna. Costa Rica se ha caracterizado por ser un país poseedor de una rica biodiversidad. Sin embargo, muchos de los ríos de la Gran Área Metropolitana ya presentan una contaminación severa, según el Índice holandés de clasificación de la calidad del agua. En este estudio se analizó el contenido de colifor- mes fecales en 10 ríos de las provincias de San José, Alajuela, Heredia y Car tago, así como de la Península de Osa. Para correlacionar el contenido de colifor- mes fecales con la densidad poblacional, además, se muestrearon tres puntos en cada río: la zona alta cercana a la naciente, la zona media y la zona baja cercana a su desembocadura. Se encontró que los puntos de muestreo con densi- dades poblacionales medias o altas están altamente contaminados con coliformes fecales.Varios de ellos superan el límite máximo permisible en el contenido de coliformes fecales establecido por los reglamen- tos nacionales para el uso de los ríos en actividades de recreación de contacto primario. También se determinó que las zonas con menor pobla- ción, tales como los ríos Tigre y Rincón en la Península de Osa, el río Poás en Alajuela en todo su recorrido y los ríos Purires y Birrís en Cartago, en sus zonas medias y altas, están menos

  20. Reduced hippocampal volume in healthy young ApoE4 carriers: an MRI study.

    Full Text Available The E4 allele of the ApoE gene has consistently been shown to be related to an increased risk of Alzheimer's disease (AD. The E4 allele is also associated with functional and structural grey matter (GM changes in healthy young, middle-aged and older subjects. Here, we assess volumes of deep grey matter structures of 22 healthy younger ApoE4 carriers and 22 non-carriers (20-38 years. Volumes of the nucleus accumbens, amygdala, caudate nucleus, hippocampus, pallidum, putamen, thalamus and brain stem were calculated by FMRIB's Integrated Registration and Segmentation Tool (FIRST algorithm. A significant drop in volume was found in the right hippocampus of ApoE4 carriers (ApoE4+ relative to non-carriers (ApoE4-, while there was a borderline significant decrease in the volume of the left hippocampus of ApoE4 carriers. The volumes of no other structures were found to be significantly affected by genotype. Atrophy has been found to be a sensitive marker of neurodegenerative changes, and our results show that within a healthy young population, the presence of the ApoE4+ carrier gene leads to volume reduction in a structure that is vitally important for memory formation. Our results suggest that the hippocampus may be particularly vulnerable to further degeneration in ApoE4 carriers as they enter middle and old age. Although volume reductions were noted bilaterally in the hippocampus, atrophy was more pronounced in the right hippocampus. This finding relates to previous work which has noted a compensatory increase in right hemisphere activity in ApoE4 carriers in response to preclinical declines in memory function. Possession of the ApoE4 allele may lead to greater predilection for right hemisphere atrophy even in healthy young subjects in their twenties.

    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

    2013-10-15

    As is generally known, the governing parties CDU/CSU and FDP agreed a few weeks ago in the 17{sup th} legislative period of the German Bundestag in a rare show of unanimity, together with the parties SPD and Buendnis 90/Die Gruenen, as well as with the Laender, on a &apos;law to search and select a location for a permanent disposal site for heat-generating radioactive waste products and to change other laws&apos;, in brief a location selection act also called StandAG. The law was received with animated approval from the ranks of the parties - with the exception of the (left-wing) party Die Linke. This praise is a tad bewildering, since the Bundesumweltministerium (Federal Department of the Environment) named solving the task within a single generation as one of the principles for the StandAG, and it was emphasised again and again in the debates about the StandAG that the problem of permanent disposal must not be shifted to the next generation. Conclusion: - The StandAG leads to a postponement of solving the permanent disposal site issue by a least several generations with its predictable, long-winded selection method. - The decision not to explore Gorleben conclusively could lead to the site being permanently (&apos;wasted&apos; or) &apos;burned&apos;. - The de-central, interim disposal site Gorleben is likewise &apos;burned&apos; without having a resilient alternative solution for the glass coquilles that must be taken back. - The people&apos;s protest is exponentiated by the number of the potential sites for the StandAG. - The costs for the alternative site search will not be shifted to the producers of the waste that are obliged by law to deliver the waste because of the financial provisions of the constitution. - The third party protection dogma has not been broken up, which will at least lead to delays in the procedure and will have effects on other major projects in the long run.

    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.)

  9. Do &apos;&apos;surrogate emissions&apos;&apos; constitute in-built leakage of the Kyoto Protocol flexible mechanisms?

    &apos;Surrogate emissions&apos; is a neologism coined to describe GHG emissions resulting from the production of intermediate goods in developing countries for industrial processing in industrialized countries, especially where the same transnational corporation controls these goods. Where upstream industrial processes extend to other developed countries, the leakage caused by this phenomenon does not arise. This is because all developed countries have QELROs. Thus, all emissions take place within the Annex I area and are covered by the QELROs. However, where the upstream processes ramify into developing countries, the associated GHG emissions are vented off, as it were, into an open system. The paper suggests that, for a complete picture of GHG emissions resulting from the industrial activities of Annex I Parties to the UNFCCC, these surrogated emissions should be incorporated into their national inventories. Otherwise, the emissions trading scheme under the auspices of the Kyoto Protocol would be undermined. (Author)

    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.

    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.

    Currently, there is no reliable method to differentiate acute from chronic carotid occlusion. We propose a novel CTA-based method to differentiate acute from chronic carotid occlusions that could potentially aid clinical management of patients. We examined 72 patients with 89 spontaneously occluded extracranial internal carotids with CT angiography (CTA). All occlusions were confirmed by another imaging modality and classified as acute (imaging <1 week of presumed occlusion) orchronic (imaging >4 weeks), based on circumstantial clinical and radiological evidence. A neuroradiologist and a neurologist blinded to clinical information determined the site of occlusion on axial sections of CTA. They also looked for (a) hypodensity in the carotid artery (thrombus), (b) contrast within the carotid wall (vasa vasorum), (c) the site of the occluded carotid, and (d) the &apos;&apos;carotid ring sign&apos;&apos; (defined as presence of a and/or b). Of 89 occluded carotids, 24 were excluded because of insufficient circumstantial evidence to determine timing of occlusion, 4 because of insufficient image quality, and 3 because of subacute timing of occlusion. Among the remaining 45 acute and 13 chronic occlusions, inter-rater agreement (kappa) for the site of proximal occlusion was 0.88, 0.45 for distal occlusion, 0.78 for luminal hypodensity, 0.82 for wall contrast, and 0.90 for carotid ring sign. The carotid ring sign had 88.9% sensitivity, 69.2% specificity, and 84.5% accuracy to diagnose acute occlusion. The carotid ring sign helps to differentiate acute from chronic carotid occlusion. If further confirmed, this information may be helpful in studying ischemic symptoms and selecting treatment strategies in patients with carotid occlusions. (orig.)

  15. Depositional &apos;'cyclicity'&apos; on carbonate platforms: Real-world limits on computer-model output

    Computer-models which attempt to define interactions among dynamic parameters believed to influence the development of &apos;'cyclic'&apos; carbonate platform sequences have been popularized over the past few years. These models typically utilize vectors for subsidence (constant) and cyclical (sinusoidal) eustatic sea-level to create accommodation space which is filled by sedimentation (depth-dependent rates) following an appropriate lag time (non-depositional episode during initial platform flooding). Since these models are intended to reflect general principles of cyclic carbonate deposition, it is instructive to test their predictive utility by comparing typical model outputs with an actively evolving depositional cycle on a modern carbonate platform where rates of subsidence, eustatic sea-level and sediment accumulation are known. Holocene carbonate deposits across northern Great Bahama Bank provide such an ideal test-platform for model-data comparisons. On Great Bahama Bank, formation of accommodation space depends on eustatic sea-level rise because tectonic subsidence is very slow. Contrary to typical model input parameters, however, the rate of formation of accommodation space varies irregularly across the bank-top because irregular bank-top topography (produced by subaerial erosion and karstification) results in differential flooding of the platform surface. Results of this comparison indicate that typical computer-model input variables (subsidence, sea-level, sedimentation, lag-time) and output depositional geometries are poorly correlated with real depositional patterns across Great Bahama Bank. Since other modern carbonate platforms and ancient carbonate sequences display similarly complex stratigraphies, it is suggested that present computer-modeling results have little predictive value for stratigraphic interpretation.

  17. 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

    The response of a variety of W material grades to nanostructure &apos;fuzz&apos; formation is explored. W targets are exposed to He or D{sub 2}-0.2He plasmas in PISCES-B at 900-1320 K to below sputter threshold He{sup +} ions of energy 25-60 eV for up to 2.2 x 10{sup 4} s. SEM and XPS reveal nanoscopic reorganization of the W surface to a layer of &apos;fuzz&apos; of porosity {approx}90% as determined by a &apos;fuzz&apos; removal/weight loss method. The variability of &apos;fuzz&apos; growth is examined at 1120 K for 1 h durations: SR, SC and doped W grades - La{sub 2}O{sub 3} (1% wt.), Re (5% and 10% wt.), and TiC (1.5% wt.) developed 2-3 {mu}m thick &apos;fuzz&apos; layers, while a VPS grade developed a layer 4 {mu}m thick. An RC grade revealed additional &apos;fuzz&apos; at deep (>100 {mu}m) grain boundaries. However, heat treatment up to 1900 K produced reintegration of &apos;fuzz&apos; with the bulk and He release at {approx}1000 K and {approx}1400-1800 K due to depopulation from vacancy complexes.

    In Sweden the utilization of forest fuels exceeds 5 million m{sup 3}/a. Two different solutions have been developed for compacting of the logging residues of final fellings. The operating principles of these methods differ from each other. Both these methods compress logging residues to &apos;energy logs&apos;, which can be processed and transported by ordinary forest machines and lorries, used for harvesting of timber. Fiberpack Ab has developed a machine which can compress logging residues or trees without any larger restrictions for raw material. Long tops and trees under 30 cm diameter can be compressed into cylindrical pieces, the diameter of which are 0.7 m, while the length can be defined freely. However, in practical operation the length is usually 3.2 m which enables in long-distance transportation the full load of a timber-lorry. In principle the Fiberpack can produce as long energy log as the amount of logging residues enable. Transportation defines the length of the log. Fiberpac-unit weights six tons, and the width in operational condition is 5.8 m. The length of the unit is 2.4 m and the height 1.9 m. The operation of the equipment has been reliable. Compacting of the logging residues occurs in three stages. In pre-compassion the residues are compressed between two rollers, in the second stage it is compressed further in square-shaped frame, after which it undergoes final compression and binding. The average weight of the &apos;logs&apos; is 550 kg. A normal timber-trailer takes 65-70 logs. The production of Fiberpac is 15-20 logs per hour. Frozen and snowy raw material is the hardest raw material, but both fresh and dried logging residues can be used for production of logs. The price of one Fiberpac-unit is about 1.4 million SEK. Another alternative is the machine developed by Wood Pac Ab, which resembles a cigarette roller. A medium-sized forest machine is used as the basic machine. The minimum power demand is 120 kW, and the efficiency of the

The spring-loaded gland packing and, according to the relevant literature, the double gland packing with barrier fluid and exhausting, which is not examined here, do provide a potential alternative for lower load-cycle numbers. The fact that design specifications and the packing and valve manufacturers&apos; installation instructions were taken into account for valve stem surfaces, gap tolerances, packing-ring arrangement, and tightening torques for precompression and final compression, was decisive for fulfillment of the requirements of TA Luft, VDI 2440 in the tests examined in this article.

    Novel technologies often are born prior to identifying application arenas that can provide the financial support for their development and maturation. After creating new technologies, innovators rush to identify some previously difficult-to-meet product or process challenge. In this regard, microsystems technology is following a path that many other electronic technologies have previously faced. From this perspective, the development of a robust technology follows a three-stage approach. First there is the &apos;&apos;That idea will never work.&apos;&apos; stage, which is hurdled only by proving the concept. Next is the &apos;&apos;Why use such a novel (unproven) technology instead of a conventional one?&apos;&apos; stage. This stage is overcome when a particular important device cannot be made economically--or at all--through the existing technological base. This initial incorporation forces at least limited use of the new technology, which in turn provides the revenues and the user base to mature and sustain the technology. Finally there is the &apos;&apos;Sure that technology (e.g., microsystems) is good for that product (e.g., accelerometers and pressure sensors), but the problems are too severe for any other application&apos;&apos; stage which is only overcome with the across-the-board application of the new technology. With an established user base, champions for the technology become willing to apply the new technology as a potential solution to other problems. This results in the widespread diffusion of the previously shunned technology, making the formerly disruptive technology the new standard. Like many technologies in the microelectronics industry, the microsystems community is now traversing this well-worn path. This paper examines the evolution of microsystems technology from the perspective of Sandia National Laboratories&apos; development of a sacrificial surface micromachining technology and the associated infrastructure.

    Diorites previously attributed to an early stage of the &apos;brasiliano&apos; plutonic evolution of the Serido belt yielded U-Pb zircon age of 579 [+-]7 Ma. The age of associated granites is slightly younger although a synchronous emplacement of granites and diorites is suggested by field relationships. Such an age difference may result from difficulties to distinguish &apos;crystallization age&apos; from &apos;emplacement age&apos;, which is still to be determined precisely.

    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.

    Full Text Available BACKGROUND: The epsilon2, epsilon3, and epsilon4 alleles of the apolipoprotein E gene (APOE encode three isoforms, apoE2, E3, and E4, respectively. The apoE isoforms circulate in different plasma concentrations, but plasma concentrations of the same isoform also differ between individuals. Whereas the isoforms have been associated with cardiovascular disease, the relation between plasma apoE levels and cardiovascular disease is unknown. METHODS AND FINDINGS: We assessed APOE genotypes, plasma levels of apoE, cardiovascular risk factors, and mortality in a population-based sample of 546 individuals aged 85 y who participated in the Leiden 85-plus Study and were prospectively followed for specific causes of death for 5 y. Participants in the highest tertile of apoE levels suffered a twofold-increased risk of cardiovascular mortality (hazard ratio compared to lowest tertile, 2.08; 95% confidence interval [CI], 1.30 to 3.33. Among the 324 participants with the epsilon3epsilon3 genotype, the hazard from cardiovascular disease was threefold increased (highest versus lowest tertile 3.01; 95% CI 1.60 to 5.66, with similar estimates for men and women. Other causes of death were not increased significantly. Plasma levels of apoE in epsilon3epsilon3 participants were positively correlated with total cholesterol (p < 0.001, low-density lipoprotein cholesterol (p < 0.001 and triglycerides (p < 0.001 and negatively with high-density lipoprotein cholesterol levels (p = 0.010. Adjustment for plasma lipids did not change the hazard ratios, whereas interaction was absent. The risk associated with high levels of apoE, however, was strongest in participants from the lowest tertile of C-reactive protein (CRP levels and absent in those from the highest tertile (p(interaction < 0.001. Among participants from the lowest tertile of CRP levels, those with a high apoE levels had a significantly steeper increase in CRP than those with low apoE levels (p = 0.020. Similar

    System dynamics has been seen primarily as a strategic tool, most effectively used at the highest level of strategy to identify robust policy interventions under a wide range of scenarios. However, an alternative, complementary and powerful role is emerging. This is at an &apos;intermediate level&apos; in organisations to coordinate and integrate policies across the value chain. It is at this level where business value, as defined by the discounted value of future free cash flow, is both created and destroyed. This paper introduces the need for &apos;intermediate-level&apos; and &apos;value-based&apos; modelling and emphasises the natural role of system dynamics in supporting a methodology to fulfil the need. It describes the development of an approach and its application in the oil industry to coordinate the response of people and tools within operational, financial and commercial functions across the value chain to address a variety of problems and issues.

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 Einstein-Rosen &apos;bridge&apos; wormhole solution proposed in the classic paper (Einstein and Rosen (1935) ) does not satisfy the vacuum Einstein equations at the wormhole throat. We show that the fully consistent formulation of the original Einstein-Rosen &apos;bridge&apos; requires solving Einstein equations of bulk D=4 gravity coupled to a lightlike brane with a well-defined world-volume action. The non-vanishing contribution of Einstein-Rosen &apos;bridge&apos; solution to the right-hand side of Einstein equations at the throat matches precisely the surface stress-energy tensor of the lightlike brane which automatically occupies the throat (&apos;horizon straddling&apos;) - a feature triggered by the world-volume lightlike brane dynamics.

    This article takes a look at two housing estates in the suburbs of Zurich, Switzerland, that conform to &apos;Minergie&apos; low energy-consumption standards. In contrast to single-family homes normally associated with the &apos;Minergie&apos; low energy-consumption label, here, two &apos;Minergie&apos; housing estates each with a number of apartment blocks are looked at. The systems for providing regulated fresh air with heat recovery are described. In one of the estates, heat is collected from a nearby sewer via heat-exchangers and, together with a heat-pump system, is used to heat the apartments. Nearby, in the other &apos;Minergie&apos; estate, a large, mains-connected photovoltaics plant is used to meet the net power requirements of a heat-pump-based heating system. In summer, power is sold to the local electricity utility.

Those in positions of power and influence in one country should take care to be as responsible in their dealings with their neighbours as they are in handling domestic matters of state. Those who see &apos;danger&apos; where there is none are not being good neighbours. They are generating fear and alarm without good cause and should mind their own business.

    One of the key ingredients of Connes&apos;s noncommutative geometry is a generalized Dirac operator which induces a metric (Connes&apos;s distance) on the pure state space. We generalize such a Dirac operator devised by Dimakis et al, whose Connes distance recovers the linear distance on an one-dimensional lattice, to the two-dimensional case. This Dirac operator has the local eigenvalue property and induces a Euclidean distance on this two-dimensional lattice, which is referred to as &apos;natural&apos;. This kind of Dirac operator can be easily generalized into any higher-dimensional lattices. (author)

    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)

The report is focused on ageing and rehabilitation of natural gas transmission pipelines and more in detail on the following topics: - Definition of pipeline ageing; - Different ageing elements; - Main causes of ageing; - Inspections and monitoring; - Repair methods on ageing pipelines; - Programmes and strategies for pipeline maintenance and rehabilitation. The report includes the state of the art of the different techniques used to assess pipeline ageing such as pig inspection, landslide areas monitoring as well as advanced monitoring methods used nowadays by pipeline operators; a clarification of the concepts for different maintenance approaches is also presented. In addition the report gives some information regarding repair methods in use, the methodologies to evaluate the defects and the philosophy on which each repair system is based. The remaining topics deal with the strategies of pipelines and coating rehabilitation, locus the attention in the economical and technical considerations also beyond the ageing concept and describe in details the main causes of ageing as indicated by operators. A questionnaire on these topics was in fact distributed and the obtained results are included in this report. (author)

    This paper reviews the trends in society, technology and energy demand of the past 30 years, together with the growth of the &apos;on-demand&apos; culture. The &apos;24/7&apos; or &apos;always on&apos; society can be defined as one where people demand - and generally receive - what they want &apos;now&apos;. It has grown up in parallel with developments in information technology, which have produced the services needed to meet that demand. Larger numbers of appliances, resulting from greater affluence and disposable income, have increased energy use, despite energy efficiencies in other areas. While monetary factors suggest that changes brought about by the 24/7 society will generally be self-correcting at the macro-economic level, there will nevertheless be effects for individuals, such as potentially severe impacts on the fuel poor as electricity prices rise. We conclude with a view of future directions. As the 24/7 culture continues to grow, there is scope for designers and for information technology to manage and reduce energy consumption. This includes buildings, their services systems, and the mix of new technologies that will be deployed over the next 20 years or so, including the possibilities for data exchange and control at the interface between energy suppliers and consumers, coupled with greater understanding of the behaviour of the consumers themselves.

    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

    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

    2002-01-01

    The objective of this research is to develop an algorithm for the sodium boiling modeling, essential to the KALIMER HCDA Analysis. The basic theory is based on the &apos;Muti-slug Ejection Model&apos; in SAS2A. It allows a finite number of bubbles in a channel at any time, and a formed bubble fills the whole cross section of the coolant channel except for liquid film left on the cladding surface. The essence of the model is to estimate the bubble pressure and temperature by balancing the bubble state change with the energy transfer into the bubble at both the wall and interfaces. It assumes that the bubble is saturated with a uniform pressure and temperature, and a bubble is generated when the coolant temperature exceeds a specified superheat. The period of the algorithm development has been divided into two phases. The algorithm development and application during the first phase is limited to the active fuel region where relatively simple physical phenomena are anticipated under ULOHS accident conditions in KALIMER, because it is favorable to the verification of the basic algorithm. The main revision is made during the 2nd phase to take into account mass transfer between the liquid film and bubble, bubble collapse, and coalescence as a liquid slug diminishes. In conclusion, the model represents the anticipated physical phenomena reasonably. The bubble has grown rapidly in consistence with the previous model predictions. Instability, however, is found in the wall heat transfer because the bubble size exceeds a certain value, over which the homogeneous model is no longer valid. Therefore, the model is expected to be improved by taking account of the pressure drop due to vapor flow inside such a large bubble to extend its applicability.

    To improve efficiency and to increase profits the oil industry will leave no stone unturned in its quest for the latest in technological development. The most recent venture is in the field of biotechnology; it involves an attempt to harness a newly-discovered variety of bacteria to improve oil sands production. It is the objective of the newly created NSERC-Syncrude Chair in Oil Sands Research, established recently at the University of Alberta with grants totalling $3.5 million. The plan is not only to push the envelope, but to develop an a whole new envelope to turn black bitumen into gold crude oil by going beyond the currently limited uses of biotechnology in environmental cleanups to incorporate bacteria into the production process. The centre of attention is the Pseudomonas bacteria that consumes nitrogen, a common impurity in crude oil, and converti it into ammonia. The result is that at least theoretically, the bacteria can replace high pressure hydrogenation, the costly process used by refineries. The process appears to work in the laboratory but industrial scale trials are still to come. Research of the planned intensive effort will be published and available to the entire industry; it will be up to industry and refineries to develop proprietary applications of the new knowledge. The fundamental research work is expected to take about five years, but other items on the agenda, such as improvements to &apos;coking&apos; to reduce solid wastes and increase the liquid yield of the initial phases of oil sands production are expected to be available much sooner. Development of catalysts to improve the quality and volume of final synthetic oil output is also one of the research objective of this newly endowed chair.

    An RIA has been developed for 3&apos;5&apos;-diiiodothyronine (3&apos;,5&apos;-T/sub 2/) in unextracted serum. Interference in binding of radioactive 3&apos;,5&apos;-T/sub 2/ to anti-3&apos;,5&apos;-T/sub 2/ was minimized by using phosphate buffer and merthiolate. The detection threshold of the RIA was 2.5 ng/dl. Recovery of nonradioactive 3&apos;,5&apos;-T/sub 2/ averaged 99%. T/sub 4/, T/sub 3/, and rT/sub 3/ cross-reacted with anti-3&apos;,5&apos;-T/sub 2/ antibody 0.0025, < 0.0004, and 0.22%, respectively. The 3&apos;-monoiodothyronine cross-reacted 1.7%. Mean serum 3&apos;,5&apos;-T/sub 2/ concentrations in ng/dl were 2.4 in 53 normal subjects, 4.2 in 7 hypothyroid patients, 14.9 in 34 hyperthyroid patients, 13.5 in 25 patients with hepatic cirrhosis, and 14.3 in 31 newborns&apos; cord blood serum. The values for the latter four groups were significantly different from normal. The serum 3&apos;,5&apos;-T/sub 2/ concentration of 7.7 ng/dl in eight subjects in the third trimester of pregnancy did not differ from normal when serum T/sub 4/ and T/sub 3/ were elevated. Oral administration of 300 ..mu..g rT/sub 3/ to 9 normal subjects led to an increase in serum 3&apos;5&apos;-T/sub 2/ concentration of 45% at 1h. Total fasting in 3 obese subjects was associated with an increase in serum 3&apos;,5&apos;-T/sub 2/ from 8.6 to 16.3 ng/dl at 6 to 8 days; rT/sub 3/ increased similarly, while T/sub 3/ decreased and T/sub 4/ did not change. Administration of dexamethasone to 4 hyperthyroid patients was associated with nearly parallel increases in serum 3&apos;,5&apos;-T/sub 2/ and rT/sub 3/ and a decrease in T/sub 3/. The 3&apos;,5&apos;-T/sub 2/ concentrations in amniotic fluids were 15.2 ng/dl at 15 to 20 weeks gestation and 5.8 ng/dl at 33 to 40 weeks. Pronase hydrolysates of 9 normal thyroid glands contained 350 ..mu..gT/sub 4/ and 0.24 ..mu..g 3&apos;,5&apos;-T/sub 2//g wet wt. It was estimated that thyroidal secretion contributes < 1% of 3&apos;,5&apos;-T/sub 2/ in

    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 alleles that are detrimental to health, especially in older age, are thought to persist in populations because they also confer some benefits for individuals (through antagonistic pleiotropy). The ApoE4 allele at the ApoE locus, encoding apolipoprotein E (ApoE), significantly increases risk of poor health, and yet it is present in many populations at relatively high frequencies. Why has it not been replaced by natural selection with the health-beneficial ApoE3 allele? ApoE is a major supplier of cholesterol precursor for the production of ovarian oestrogen and progesterone, thus ApoE has been suggested as the potential candidate gene that may cause variation in reproductive performance. Our results support this hypothesis showing that in 117 regularly menstruating women those with genotypes with at least one ApoE4 allele had significantly higher levels of mean luteal progesterone (144.21 pmol l(-1)) than women with genotypes without ApoE4 (120.49 pmol l(-1)), which indicates higher potential fertility. The hormonal profiles were based on daily data for entire menstrual cycles. We suggest that the finding of higher progesterone in women with ApoE4 allele could provide first strong evidence for an evolutionary mechanism of maintaining the ancestral and health-worsening ApoE4 allele in human populations.

    OAK (B204) Final Report, NERI Project: &apos;&apos;An Innovative Reactor Analysis Methodology Based on a Quasidiffusion Nodal Core Model&apos;&apos; The present generation of reactor analysis methods uses few-group nodal diffusion approximations to calculate full-core eigenvalues and power distributions. The cross sections, diffusion coefficients, and discontinuity factors (collectively called &apos;&apos;group constants&apos;&apos;) in the nodal diffusion equations are parameterized as functions of many variables, ranging from the obvious (temperature, boron concentration, etc.) to the more obscure (spectral index, moderator temperature history, etc.). These group constants, and their variations as functions of the many variables, are calculated by assembly-level transport codes. The current methodology has two main weaknesses that this project addressed. The first weakness is the diffusion approximation in the full-core calculation; this can be significantly inaccurate at interfaces between different assemblies. This project used the nodal diffusion framework to implement nodal quasidiffusion equations, which can capture transport effects to an arbitrary degree of accuracy. The second weakness is in the parameterization of the group constants; current models do not always perform well, especially at interfaces between unlike assemblies. The project developed a theoretical foundation for parameterization and homogenization models and used that theory to devise improved models. The new models were extended to tabulate information that the nodal quasidiffusion equations can use to capture transport effects in full-core calculations.

    The machine &apos;'Shtrek'&apos; is described. It makes it possible to mechanize over 20 auxiliary operations: loading-unloading operations: extraction of old and deformed timbering; dissmantling of obstructions; erection of different types of timbering; making and restoring of drainage channels; laying and straightening of a drift and its leveling; assembly and disassembly of pipelines and mine equipment, etc. Depending on the type of operation, the machine has the corresponding suspended equipment. The elementary variant has a limited area of application at mines of the central region of the Dunbass. Currently a pneumatic variant of the machine &apos;'Shtrek'&apos; has been developed. The electric motor and the starter of the pumping equipment of the machine have been replaced by a pneumatic motor and pneumatically controlled valve KTM-50. In this case there was significant reduction in the weight of the pumping equipment and in its overall dimensions; the electric drive of the hydraulic distributors for controlling the mechanisms were replaced by simpler pneumatic ones; the logical circuit of the control system was constructed on the USEPPA elements. A specialized tractor-lifter designed for moving suspended loads is described for auxiliary operations in the near-face zone of the preparatory drifts. The machine also lifts and lowers the boom, rotates the boom by 270/sup 0/ and additionally lifts and lowers the weight-lifting hook.

    Europe&apos;s energy policy has been completely transformed over the last few years, tackling the dual challenges of climate change and energy security. This has lead to major new laws on issues such as energy liberalisation, renewable energy and energy efficiency. In this volume the detailed reasons for these changes are outlined and the way in which the European Union has risen to these challenges is discussed. Views are given on where Europe&apos;s energy policy will go next, the challenges of 2050 and the development of a &apos;third industrial revolution&apos;. This insight is complemented by the observations and comments of some of the leading figures concerning European and global energy issues, explaining how industry, energy regulators and global thinkers see Europe&apos;s energy policy and the challenges that it now faces.

    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.

  8. Fair Miles? The concept of &apos;food miles&apos; through a sustainable development lens

    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.

  11. Targeted In Situ Gene Correction of Dysfunctional APOE Alleles to Produce Atheroprotective Plasma ApoE3 Protein

    Full Text Available Cardiovascular disease is the leading worldwide cause of death. Apolipoprotein E (ApoE is a 34-kDa circulating glycoprotein, secreted by the liver and macrophages with pleiotropic antiatherogenic functions and hence a candidate to treat hypercholesterolaemia and atherosclerosis. Here, we describe atheroprotective properties of ApoE, though also potential proatherogenic actions, and the prevalence of dysfunctional isoforms, outline conventional gene transfer strategies, and then focus on gene correction therapeutics that can repair defective APOE alleles. In particular, we discuss the possibility and potential benefit of applying in combination two technical advances to repair aberrant APOE genes: (i an engineered endonuclease to introduce a double-strand break (DSB in exon 4, which contains the common, but dysfunctional, ε2 and ε4 alleles; (ii an efficient and selectable template for homologous recombination (HR repair, namely, an adeno-associated viral (AAV vector, which harbours wild-type APOE sequence. This technology is applicable ex vivo, for example to target haematopoietic or induced pluripotent stem cells, and also for in vivo hepatic gene targeting. It is to be hoped that such emerging technology will eventually translate to patient therapy to reduce CVD risk.

    ApoE is a polymorphic protein involved in the metabolism of plasma lipoproteins; the ε4 allele was shown to be associated with coronary and aortic atherosclerosis in age-dependent fashion mediated by unknown mechanisms. This study was undertaken to assess whether the apoE isoforms in humans were associated with normal glucose tolerance and with metabolic and inflammatory risk factors of CVD. ApoE genotype was assessed in 365 individuals. Of those, 309 were studied in the postabsorptive conditions and 142 of them also underwent a 3h-OGTT; 56 additional subjects were studied by means of the insulin clamp in combination with [6,6-2H2] glucose infusion. ApoE genotype frequencies were similar to those previously reported and were not influenced by age and BMI. Fasting plasma glucose, insulin, FFA, the lipid profile, surrogate markers (HOMA-IR, OGTT-derived index) as well as the clamp-derived parameters or insulin sensitivity and insulin secretion were not different by apoE genotypes. Serum adipokines concentrations (leptin, adiponectin, resistin) and markers of inflammation (serum fasting hsCRP and MCP1/CCL2) were also not different by apoE genotypes. In the subgroup of young ε4 carriers which underwent the clamp procedure, a higher fasting endogenous glucose production was detected. ApoE genotype was not associated with insulin resistance or altered insulin secretion, and no abnormalities in the typical circulating endocrine, metabolic, and inflammatory features of the insulin resistance syndrome were detected.

    Should one correct for extrathyroidal neck radioactivity (&apos;&apos;neck background&apos;&apos;) when interpreting perchlorate discharge test results A new background correction method was developed using a linear probe. [sup 123]I produces photon peaks at two energy levels: 159 keV ([gamma]-rays) and 28 keV (X-rays), with an attenuation of 15 and 35% per cm water, respectively. If one fixes the position of the subject&apos;s neck, radiation from thyroid [sup 123]I produces an X/[gamma] detection ratio ([alpha]) which is constant and, due to the anterior localization of the thyroid, higher than the ratio ([beta]) produced by extrathyroidal [sup 123]I. These two ratios can be determined in vivo and used to calculate background-corrected and depth-corrected thyroid uptake. In simulation experiments our method was effective so long as the &apos;'gland'&apos; was situated close enough to the &apos;'neck'&apos; surface for the difference ([alpha]-[beta]) to be less than 0.19. Perchlorate discharge tests were performed in five euthyroid subjects who were pretreated with methimazole. The difference ([alpha]-[beta]) ranged from 0.27 to 0.36. Uncorrected, the mean discharge was 57% (range 47-66); corrected, it was 92% (range 88-94). In 15 hyperthyroid Graves&apos; patients, with goitres varying from 13 to 63 ml, [alpha]-[beta] ranged from 0.22 to 0.40 and was unrelated to goitre size. The contribution of neck background is quantitatively important, especially when thyroid uptake is low; our new method corrects for it, even with large goitres. (Author).

  14. Germany steps up pressure on Fessenheim, but is the &apos;Energiewende&apos; all-knowing?

    Shepherd, John [nuclear 24, Brighton (United Kingdom)

    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.

    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

    This report deals with the works undertaken by working committee 10 during the 1997 - 2000 Triennium. 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)

    Service pipes are constitute an important link in the gas distribution chain. By their numbers, their relative weakness against third party aggressions and due to the fact that they constitute in most cases the limit of responsibility between the gas company network and customers&apos; installations, service pipes have been identified as a technical and economical key issue for the gas industry development. This document analyses technical and economical data dealing with domestic service pipes having a maximum flow rate of 10 m3/h collected from 42 gas companies spread over 22 countries. All service pipes elements, from the connection with the distribution network up to the delivery point, are analysed emphasizing their layouts and design, the materials used, the construction techniques, the operating and maintenance policies and a few rehabilitation techniques. The main different technical solutions given by the gas companies have been compared in order for the study group to draw up some recommendations regarding the best practices in terms of safety, ease of maintenance and economical savings.

    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). [German] Der deutsche Markt fuer die technisch ausgereiften solarthermischen Anlagen zur Warmwassererzeugung waechst mit ca. 20% p.a., mit foerderpolitisch bedingten Schwankungen.

    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. We cannot eliminate the possibility of a CH{sub 4} atmosphere, but place upper surface pressure and mean temperature limits of {approx}138 nbar and {approx}44 K, respectively.

    The Waste Isolation Pilot Plant (WIPP) site, which is managed and operated by the United States (U.S.) Department of Energy (USDOE) Carlsbad Field Office (CBFO) and located in the State of New Mexico, presently hosts an underground research laboratory (URL) and the world&apos;s first certified and operating deep geological repository for safe disposition of long-lived radioactive materials (LLRMs). Both the URL and the repository are situated approximately 650 meters (m) below the ground surface in a 250-million-year-old, 600-m-thick, undisturbed, bedded salt formation, and they have been in operation since 1982 and 1999, respectively. Founded on long-standing CBFO collaborations with international and national radioactive waste management organizations, since 2001, WIPP serves as the Center of Excellence in Rock Salt for the International Atomic Energy Agency&apos;s (IAEA&apos;s) International Network of Centers on &apos;&apos;Training in and Demonstration of Waste Disposal Technologies in Underground Research Facilities&apos;&apos; (the IAEA Network). The primary objective for the IAEA Network is to foster collaborative projects among IAEA Member States that: supplement national efforts and promote public confidence in waste disposal schemes; contribute to the resolution of key technical issues; and encourage the transfer and preservation of knowledge and technologies.

    Detailed synthesis of the bifunctional chelating agents 2-methyl-6-(p-isothiocyanatobenzyl)-1,4,7,10-tetraazacyclododecane-1,4,7,10 -tetraacetic acid (1B4M-DOTA) and 2-(p-isothiocyanatobenzyl)-5, 6-cyclohexano-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetate (CHX-DOTA) are reported. These chelating agents were compared to 2-(p-isothiocyanatobenzyl)-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (C-DOTA) and 1, 4, 7, 10-Tetraaza-N-(1-carboxy-3-(4-nitrophenyl)propyl)-N&apos;, N&apos;&apos;, N&apos;'&apos;-tris(acetic acid) cyclododecane (PA-DOTA) as their {sup 177}Lu radiolabeled conjugates with Herceptin{sup TM}. In vitro stability of the immunoconjugates radiolabeled with {sup 177}Lu was assessed by serum stability studies. The in vivo stability of the radiolabeled immunoconjugates and their targeting characteristics were determined by biodistribution studies in LS-174T xenograft tumor-bearing mice. Relative radiolabeling rates and efficiencies were determined for all four immunoconjugates. Insertion of the 1B4M moiety into the DOTA backbone increases radiometal chelation rate and provides complex stability comparable to C-DOTA and PA-DOTA while the CHX-DOTA appears to not form as stable a {sup 177}Lu complex while exhibiting a substantial increase in formation rate. The 1B4M-DOTAmay have potential for radioimmunotherapy applications. Published by Elsevier Inc. All rights reserved.

    The further development of a Guideline (formerly Protocol) for sampling and analysis of &apos;tars&apos; from biomass producer gases is reported. This Guideline is being developed as a project within the European Fifth Framework Programme with additional partners from Switzerland and North-America. In this paper an outline and the principle of the Guideline are given. The Guideline is based on isokinetic sampling of particles and &apos;tar&apos; from the main producer gas duct, particle filtration at high temperature, gas cooling in a liquid quench, &apos;tar&apos; absorption in a solvent at low temperatures, an optional backup adsorber, and flow measurement and control. The Guideline gives a definition for &apos;Gravimetric tar&apos; which is the &apos;tar&apos; number to be determined by the Guideline. Also, the Guideline gives procedures for compound analysis by gas chromatography - mass spectrometry (GC-MS) or gas chromatography - Flame Ionization Detector (GC-FID). Moreover, in this paper the major choices that were made to reach the first version of the Guideline are explained. Finally, at the end of the paper it is described how and on what time scale the development of the Guideline will be completed. The full text of the Guideline is available on the Internet at www.tarweb.net. 11 refs.

    The author and presenter of this paper intends to show how the PLAN project is helping to focus engineering professionals minds on &apos;helping themselves&apos; when it comes to Maintenance matters. As co- ordinator of the Maintenance Cluster of the PLAN project, the presenter will describe how the work of three Cluster Tasks, has already convinced many scientific and engineering biased professionals that adopting certain key philosophies can assist the Maintenance function to achieve performance standards previously thought unattainable. The paper will show how the use of the very latest technological developments, particularly in the Condition Monitoring field, together with &apos;Accountancy Justification&apos; can bring about &apos;Purse String Loosening Effects&apos;. The presentation will go on to show how the &apos;Purse String Loosening Effects&apos; become self perpetuating and can catapult the Maintenance function to the forefront of a business.

    INTRODUCCIÓN: se ha propuesto que la expresión de los polimorfismos de la apolipoproteína E (apoE) es un factor predisponente para el desarrollo temprano de psicosis en los pacientes con enfermedad de Parkinson. La relación entre el genotipo de la apoE y el desarrollo de complicaciones motoras es controvertida. El objetivo de esta investigación fue determinar la relación entre los polimorfismos de la apoE y su frecuencia alélica y el desarrollo de complicaciones secundarias al reemplazo dopaminérgico. MÉTODOS: se evaluaron 231 pacientes con diagnóstico de enfermedad de Parkinson. La presencia de complicaciones fue determinada por un neurólogo y se realizó la genotipificación de los polimorfismos de la apoE. Se utilizó la chi cuadrada para determinar la relación entre la presencia o ausencia de las complicaciones estudiadas y el genotipo de la apoE.

    Full Text Available BACKGROUND: Apolipoprotein E receptor 2 (ApoEr2 is a postsynaptic protein involved in long-term potentiation (LTP, learning, and memory through unknown mechanisms. We examined the biological effects of ApoEr2 on synapse and dendritic spine formation-processes critical for learning and memory. METHODOLOGY/PRINCIPAL FINDINGS: In a heterologous co-culture synapse assay, overexpression of ApoEr2 in COS7 cells significantly increased colocalization with synaptophysin in primary hippocampal neurons, suggesting that ApoEr2 promotes interaction with presynaptic structures. In primary neuronal cultures, overexpression of ApoEr2 increased dendritic spine density. Consistent with our in vitro findings, ApoEr2 knockout mice had decreased dendritic spine density in cortical layers II/III at 1 month of age. We also tested whether the interaction between ApoEr2 and its cytoplasmic adaptor proteins, specifically X11α and PSD-95, affected synapse and dendritic spine formation. X11α decreased cell surface levels of ApoEr2 along with synapse and dendritic spine density. In contrast, PSD-95 increased cell surface levels of ApoEr2 as well as synapse and dendritic spine density. CONCLUSIONS/SIGNIFICANCE: These results suggest that ApoEr2 plays important roles in structure and function of CNS synapses and dendritic spines, and that these roles are modulated by cytoplasmic adaptor proteins X11α and PSD-95.

    The aim of the study is to assess the frequency of Down&apos;s syndrome (DS) among newborns in the city of Ozyorsk located near the nuclear complex Mayak&apos;&apos;. The study has been conducted on the basis of the cohort, which includes 18,499 children born in Ozyorsk in 1974-1988. Information on cases of DS has been abstracted from newborn records at the city maternity hospital. The frequency of DS in Ozyorsk is 1.4 cases per 1,000 newborns. According to some published data, the population frequency of this syndrome is 1.25-1.42 cases per 1,000 newborns. The frequency of DS among children whose parents were occupationally exposed to radiation has been studied. The cohort has been divided into two subcohorts based on whether or not parents worked at Mayak. In 5,303 children either one or both parents worked at Mayak. The comparison group includes 13,196 children whose parents never worked at Mayak. In the children, whose parents worked at Mayak, the frequency of DS is 1.32 cases per 1000, and in the comparison group - 1.44 cases per 1000 (the difference is not statistically significant). Parental radiation doses by the time of conception of children with DS are in the range from 0.65 to 10.31 cSv. Our data confirm the effect of maternal age on the frequency of DS. The frequency of DS in children born to mother under the age of 30 is 0.94 per 1,000 and in children born to mothers older than 30 years - 3.87 per 1,000. So the frequency of DS among children born in the city located near the nuclear complex does not exceed the spontaneous level. No association has been detected between the frequency of DS and preconception parental radiation exposure. The effect of maternal age has been confirmed. (author)

If larger planetesimals were present, then they would stir the disk, triggering a collisional cascade and thus causing production of small debris, which is not seen. Thus, planetesimal formation, at least in the outer regions of the systems, has stopped before &apos;cometary&apos; or &apos;asteroidal&apos; sizes were reached.

    Full Text Available El trabajo se propone explorar las formas en que fue construyéndose desde lo discursivo, la legitimación de la última dictadura argentina en un espacio local. Para ello, se adopta una perspectiva microsocial, situando la mirada en un periódico de alcance regional. Se analizan distintos fragmentos discursivos del espacio editorial del diario La Verdad, fundado y establecido en la ciudad bonaerense de Junín. Se recurre a algunas herramientas del análisis del discurso para identificar estrategias, operaciones discursivas y recursos de valoración que utilizó ese medio para evaluar el accionar de las Fuerzas Armadas luego del golpe de 1976 y las proyecciones del régimen militar en el corto y mediano plazo. A su vez, se considera que la representación de una alteridad negativa que, en el imaginario social de la época, se sintetizó en la figura de la “subversión” tuvo un papel central para aquella legitimación en tanto se extendió esa noción a otros actores y se la encadenó semánticamente con distintos significantes en cadenas equivalenciales con una carga valorativa sumamente negativa.

    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

    Full Text Available BACKGROUND The paper engages in the ongoing debate regarding the determinants of child nutrition in developing countries and stresses the potential contribution of the education of household members other than the child&apos;s parents. OBJECTIVE The aim of the paper is threefold: (1 to verify whether there is evidence of the key role of parents&apos; education for children&apos;s nutrition; (2 to explore the possible presence of the externalities generated by the literacy of household members different from the child&apos;s parents; (3 to test whether there is difference in the influence of these variables on the two indicators of child nutrition, child height-for-age and weight-for-age. METHODS The determinants of child nutrition were analyzed by estimating a series of econometric models through OLS regressions applied on data from the 2003 DHS survey in Mozambique. By means of seemingly unrelated regression together with formal testing we compared the impact of the covariates on the two outcomes. RESULTS In line with previous studies, we find that one year of mother&apos;s education increases their children&apos;s height-for-age and weight-for-age z-scores by nearly 0.025 and 0.015. The presence of another literate household member has a significant, though limited, effect on child height while it has no influence on child weight. Lastly, there is no statistically significant difference in the effect of parents&apos; education on the two indicators while our measure of proximate literacy has a significantly larger impact on child height. CONCLUSIONS These findings should orient policy-makers toward income-augmenting and education-enhancing policies: the importance of non-parents&apos; literacy opens a further space for investment in education.

    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.

    Prussian blue (PB) is an artists&apos; pigment that has been frequently used in many artworks but poses several problems of conservation because of its fading under light and anoxia treatment. PB fading is due to the reduction of iron(III) into iron(II) and depends a lot on the object investigated. Due to the complexity of the structure, the precise physico-chemical mechanisms behind the redox process remain obscure. In this paper, we present a procedure to investigate light- and anoxia-induced fading of PB-paper samples by means of time resolved X-ray absorption spectroscopy performed at the Fe K-edge. A system composed of a visible light source and a flux-controlled environmental cell allowed light, gas and humidity to be modified in situ. The synchrotron X-ray beam was evidenced to induce a reduction of PB and to play a major role in the kinetics. The analysis of the PB fading kinetics of a sample submitted to various gas and light environments showed that both synchrotron beam and anoxia were influencing PB reduction in a correlated way. In comparison, light was found to play a minor role. Finally, we have demonstrated that the type of paper substrate could influence significantly the kinetics of reduction. Several hypotheses to explain the correlation between PB reduction mechanism and substrate are presented. (orig.)

    The results from studies of the effects produced by electrical explosions of foils made from super pure materials in water point to the emergence of new chemical elements. An additional finding was the discharge of &apos;strange&apos; radiation accompanying the transformation of chemical elements. However, currently, the mechanism involved in the interaction between &apos;strange&apos; radiation and a substance or a biological entity remains obscure. Therefore, the aim of the present research is to investigate the biological effects of the &apos;strange&apos; radiation. Pilot studies were performed at the RECOM RRC &apos;Kurchatov Institute&apos; in April-May of 2004. The animals used in the experiment were female mice of C57Bl/6 line aged 80 days with body weight 16-18 g. The animals were exposed to radiation discharged during explosions of Ti foils in water and aqueous solutions. The cages with animals were placed at 1 m from the epicenter of the explosion. Explosions were carried out on the 19. (3 explosions), 20. (4 explosions) and 22. (3 explosions) of April, 2004 (explosions No1373 - No1382, respectively). The animals were assigned to 4 experimental groups comprised of 17-20 mice per group. The animals received experimental exposure within 1, 2 and 3 days of the experiment. In total, the experimental groups were exposed to 3, 7 and 10 explosions, respectively. In order to identify the biological reactions, the following parameters were estimated: number of nucleated cells in the bone marrow, number of CFU in the spleen after additional gamma-irradiation (6 Gy), cell composition of the bone marrow, the rate of erythrocytes with the different level of maturation in the bone marrow, the rate of erythrocytes with the micronuclei in the bone marrow, the reaction of bone marrow cells to additional gamma-irradiation (2 Gy), number of leucocytes in the peripheral blood, and cell composition of the peripheral blood. The following conclusions were drawn from these

    This paper builds a basic theory of &apos;Carbon-Money Exchange&apos; in which carbon as currency in nature&apos;s household (ecosystems) and money as currency in humankind&apos;s household (economy) are exchanged just like in a foreign exchange. The simple chemical equation below makes it possible (CO{sub 2}{yields}C+O{sub 2}=C+O{sub 2}{yields}CO{sub 2}). The left-hand side represents the work of plants to remove atmospheric CO{sub 2}. The right-hand side represents the work of humans as fossil fuel consumers to produce it. The exchange of the two currencies is possible by copying the fossil fuel market. The paper concludes that this new exchange can automatically contain global warming and deforestation, replacing onerous emissions trading. Moreover, it could revolutionize the conventional economy, creating counter-capitalism, or &apos;carbonism&apos;.

    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.

    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.

    ApoE is a multifunctional protein that is expressed by many cell types that influences many aspects of cardiovascular physiology. In humans, there are three major allelic variants that differentially influence lipoprotein metabolism and risk for the development of atherosclerosis. Apoe-deficient mice and human apoE isoform knockin mice, as well as hypomorphic Apoe mice, have significantly contributed to our understanding of the role of apoE in lipoprotein metabolism, monocyte/macrophage biology, and atherosclerosis. This brief history of these mouse models will highlight their contribution to the understanding of the role of apoE in these processes. These Apoe(-/-) mice have also been extensively utilized as an atherosensitive platform upon which to assess the impact of modulator genes on the development and regression of atherosclerosis.

    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)

Companies all over the world - headed by the Japanese car makers - decided not to &apos;dabble&apos; with industrial robots anymore but to &apos;blockbust&apos; with them. Complete production processes were literally turned inside out by the compact use of robots in waves, and adjusted to the requirements of flexible manufacturing technology. To deal with the characteristic conditions and features of the new strategy as well as its implications for labour policy, it is also necessary to examine the use of robots at the plant level. This study comes to the conclusion that the plant use of robots by no means follows a continuous curve, as would appear to be the case in industry and group statistics on the development of robot inventory.

    Maffucci&apos;s syndrome consists of multiple cutaneous hemangiomas, dyschondroplasia, and enchondromas with potential for malignant change. We report a case of a 33-year-old man with Maffucci&apos;s syndrome who presented with a several month history of nasal congestion, facial pain, and diminished vision in his left eye. Radiological studies showed a large soft tissue mass centered in the sinonasal area, extending bilaterally into maxillary sinuses and orbits with compression of left optic nerve. Biopsy of the mass showed esthesioneuroblastoma (olfactory neuroblastoma). Chemotherapy resulted in initial improvement, but the tumor recurred and did not respond to further treatment, resulting in his death. Sarcomatous tumors are reported in Maffucci&apos;s syndrome, but this is a rare case of a neuroendocrine tumor in a patient with Maffucci&apos;s syndrome. (orig.)

    Riboswitches "sense" metabolites but knowledge is sparse for structures without bound ligand. Stoddard et al. (2010) determined an apo riboswitch structure "closed" to metabolite binding. Further SAXS, biochemical, and computational analyses support ensemble behavior with interconverting open and closed conformations.

    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.

    The presented method, which is characterised by the combination of fluidized bed gasification with fluidized bed cooling of the combustion gas (tar and dust inclusion in residual carbon) as well as by the complete energetic use of recyclings through fluidized bed combustion, enables a demand oriented decentral generation of electric energy and heating energy from biomass according to the regulations of the Renewable Energy Law (EEG) not only in terms of technical procedures but also in economical terms. Due to an oxygen concentration in the gasification media the &apos;&apos;CombiPower-Plus- procedure&apos;&apos; does not only generate electric energy and heating energy but also an industrial gas with a calorific value of approximately 8 MJ/kg at O{sub 2}=50 Vol.%. Furthermore the &apos;&apos;CombiPower-Plus- process&apos;&apos; achieves an increase of the fuel performance by a magnitude of 2.5 to 3 compared to the &apos;&apos;CombiPower plant&apos;&apos; that is equal in construction. A reduction of the specific investment costs from approximately 3,750 /kW (Pel) to under 2,000 /kW (Pel) can be expected. Due to the procedure no residual materials like tar, dust or waste water are generated. In case of a further price increase of energy raw materials on the international market this process enables on the hand the use of renewable combustibles like wood, which is preferred for decentral electric current generation in Germany due to the incentive regulations of the EEG, on the other hand this process also enables the economic use of regionally available brown coal as combustible for decentral energy generation.

    apoE is a multi-functional protein expressed in several cell types and in several organs. It is highly expressed in adipose tissue, where it is important for modulating adipocyte lipid flux and gene expression in isolated adipocytes. In order to investigate a potential systemic role for apoE that is produced in adipose tissue, mice were generated with selective suppression of adipose tissue apoE expression and normal circulating apoE levels. These mice had less adipose tissue with smaller adipocytes containing fewer lipids, but no change in adipocyte number compared with control mice. Adipocyte TG synthesis in the presence of apoE-containing VLDL was markedly impaired. Adipocyte caveolin and leptin gene expression were reduced, but adiponectin, PGC-1, and CPT-1 gene expression were increased. Mice with selective suppression of adipose tissue apoE had lower fasting lipid, insulin, and glucose levels, and glucose and insulin tolerance tests were consistent with increased insulin sensitivity. Lipid storage in muscle, heart, and liver was significantly reduced. Adipose tissue macrophage inflammatory activation was markedly diminished with suppression of adipose tissue apoE expression. Our results establish a novel effect of adipose tissue apoE expression, distinct from circulating apoE, on systemic substrate metabolism and adipose tissue inflammatory state.

    In this reply, we show that when we apply standard distribution theory to the Lippmann-Schwinger equation, the resulting spaces of test functions would comply with the Hardy axiom only if classic results of Paley and Wiener, of Gelfand and Shilov, and of the theory of ultradistributions were wrong. Also, we point out several differences between the &apos;standard method&apos; of constructing rigged Hilbert spaces in quantum mechanics and the method used in time asymmetric quantum theory.

    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.)

From pure end consumers they will more and more shift to energy-conscious, demanding market players acting as well as producers of energy. This breaks the traditional value chain. In order to participate on the business chances of this development utilities have to build up new, innovative business models around the smart customer. Sustainable success of these approaches depends on some key requirements. (orig.)

    The discovery of the so-called &apos;fullerines&apos;, i.e., carbon atom clusters forming closed structures, hollow within, and having an even number of sides ranging from 24 to 540, represents an interesting novelty in chemical engineering materials research. These substances are important in that they constitute a third allotropic form of carbon, exhibiting stable thermodynamic and kinetic behaviour as compared with graphite and diamond respectively. This paper focusses attention on the properties and possible applications of the C/sub 60/ and C/sub 70/ &apos;fullerines&apos; thus named due to their Buckminster Fuller type geodetic structural forms.

    This work analyzes the progressive stiffening of the aorta due to atherosclerosis development of both ApoE(-/-) and C57BL/6J mice fed on a Western (n = 5) and a normal (n = 5) chow diet for the ApoE(-/-) group and on a normal chow diet (n = 5) for the C57BL/6J group. Sets of 5 animals from the three groups were killed after 10, 20, 30 and 40 weeks on their respective diets (corresponding to 17, 27, 37 and 47 weeks of age). Mechanical properties (inflation test and axial residual stress measurements) and histological properties were compared for both strains, ApoE(-/-) on the hyper-lipidic diet and both ApoE(-/-) and C57BL/6J on the normal diet, after the same period and after different periods of diet. The results indicated that the aorta stiffness in the ApoE(-/-) and C57BL/6J mice under normal diet remained approximately constant irrespective of their age. However, the arterial stiffness in the ApoE(-/-) on the hyper-lipidic diet increased over time. Statistical differences were found between the group after 10 weeks and the groups after 30 and 40 weeks of a hyper-lipidic diet. Comparing the hyper-lipidic and normal diet mice, statistical differences were also found between both diets in all cases after 40 weeks of diet, frequently after 30 weeks, and in some cases after 20 weeks. The early stages of lesion corresponded to the first 2 weeks of diet. Advanced lesions were found at 30 weeks and, finally, the aorta was completely damaged after 40 weeks of diet. In conclusion, we found substantial changes in the mechanical properties of the aorta walls of the ApoE(-/-) mice fed with the hyper-lipidic diet compared to the normal chow diet groups for both the ApoE(-/-) and C57BL/6J groups. These findings could serve as a reference for the study of changes in the arterial wall properties in cases of atherosclerosis.

    Persistent organochlorine pollutants (POP) have, in animal studies, impaired normal bone metabolism and resulted in increased bone fragility. Especially considering the dramatical increase in osteoporotic fractures in western societies during the last decades, it is a pertinent question whether a high dietary intake of POP might pose a risk for deteriorated bone quality in humans. This problem has been assessed as a part of the collaborative project &apos;'COMPARE'&apos;, funded by European Commission RD Life Science Program. As a study base we have used cohorts of Swedish fishermen&apos;s families. We have earlier shown that fishermen living at the east coast of Sweden, have a high consumption of contaminated fatty fish from the Baltic Sea and consequently relatively high exposure levels for various POPs, also compared with fishermen from the Swedish west coast. Such a discrepancy was also found for fishermen&apos;s wives. The aim of the project was to assess in epidemiological studies whether a high dietary intake of POP through fatty fish from the Baltic may result in an increased incidence of osteoporotic fractures or decreased bone mineral density (BMD). We give here an overview of the results.

    A radioimmunoassay for guanosine-5&apos;-diphosphate-3&apos;-diphosphate (ppGpp) and adenosine-5&apos;-triphosphate-3&apos;-diphosphate (pppApp) has been developed. The assay method is based on competition of an unlabeled highly phosphorylated nucleotide with /sup 3/H-labeled highly phosphorylated nucleotide for binding sites on a specific antibody. Antibodies to ppGpp and pppApp were obtained by immunizing rabbits with the antigen prepared by conjugating ppGpp with human serum albumin using 1-ethyl-3-(3-dimethylaminoprophyl)carbodiimide, and with the antigen prepared by conjugating 8-(6-aminohexyl)amino-adenosine-5&apos;-triphosphate-3&apos;-diphosphate with human serum albumin using glutaraldehyde, respectively. Antibody-bound /sup 3/H-labeled highly phosphorylated nucleotides were separated from the free /sup 3/H-labeled highly phosphorylated nucleotides by selective adsorption on dextran-coated charcoal. Displacement plots were linear over a concentration range of 5 - 1,000 pmol/assay tube in a log-probit percentage plot. Application of this method to biological systems offers improved accuracy and convenience compared with the previous /sup 32/PO/sub 4/-labeling technique.

    Development of new technologies for application of dry tree solutions on semi-submersible hull production platforms opens up new flexible and cost efficient solutions for oil and gas fields in deep and ultra deep water. Aker Solutions has brought the technology through the last steps to a project ready stage. Top tension risers allow for shifting the Christmas tree from seabed to topside, and enables drilling and production from the same unit. By shifting the wellhead and Christmas tree from seabed to platform deck, well maintenance is simplified, and makes the Dry Tree Semi relevant to consider for the Brazilian pre-salt reservoirs. Easy access to the wells for maintenance gives a potential for a higher recovery rate for the field. Future development of ultra deep water oil and gas fields demands solutions overcoming the limitations set by the TLP and the Spar buoy. Combining knowledge from already proven solutions, and a limited addition of new technology, these limitations are overcome with Aker Solutions&apos; Dry Tree Semi. It is designed and proven for Gulf of Mexico environmental conditions. It is verified for conditions with a significant wave height of 14 meters, and able to withstand 100-year extreme weather and 1000-years survival conditions. A conventional semi-submersible platform, but with a deeper draft to further reduce the already low motions, makes the basis for the concept. Top tensioned risers (TTR) with vertical motion compensation stroke of up to 10 meters, makes it possible to shift the Christmas tree from seabed to platform deck. The deep draft design of the hull reduces the wave force excitation on the pontoons, reducing both the roll and pitch dynamics. The Dry Tree Semi represents several major benefits, including low sensitivity to water depth, reduced hull and topside weight, and flexibility in transportation, mooring, and decommissioning.

    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

  15. Augmented atherogenesis in LDL receptor deficient mice lacking both macrophage ABCA1 and ApoE.

    Directory of Open Access Journals (Sweden)

    Bart Lammers

    Full Text Available AIM: ABCA1 protects against atherosclerosis by facilitating cholesterol efflux from macrophage foam cells in the arterial wall to extracellular apolipoprotein (apo A-I. In contrast to apoA-I, apoE is secreted by macrophages and can, like apoA-I, induce ABCA1-mediated cholesterol efflux. Yet, the combined effect of macrophage ABCA1 and apoE on lesion development is unexplored. METHODS AND RESULTS: LDL receptor knockout (KO mice were transplanted with bone marrow from ABCA1/apoE double KO (dKO mice, their respective single KO's, and wild-type (WT controls and were challenged with a high-fat/high-cholesterol diet for 9 weeks. In vitro cholesterol efflux experiments showed no differences between ABCA1 KO and dKO macrophages. The serum non-HDL/HDL ratio in dKO transplanted mice was 1.7-fold and 2.4-fold (p<0.01 increased compared to WT and ABCA1 KO transplanted mice, respectively. The atherosclerotic lesion area in dKO transplanted animals (650±94×10(3 µm(2, however, was 1.9-fold (p<0.01 and 1.6-fold (p<0.01 increased compared to single knockouts (ABCA1 KO: 341±20×10(3 µm(2; apoE KO: 402±78×10(3 µm(2, respectively and 3.1-fold increased (p<0.001 compared to WT (211±20×10(3 µm(2. When normalized for serum cholesterol exposure, macrophage ABCA1 and apoE independently protected against atherosclerotic lesion development (p<0.001. Moreover, hepatic expression levels of TNFα and IL-6 were highly induced in dKO transplanted animals (3.0-fold; p<0.05, and 4.3-fold; p<0.001, respectively. In agreement, serum IL-6 levels were also enhanced in ABCA1 KO transplanted mice (p<0.05 and even further enhanced in dKO transplanted animals (3.1-fold as compared to ABCA1 KO transplanted animals; p<0.05. CONCLUSIONS: Combined deletion of macrophage ABCA1 and apoE results in a defect in cholesterol efflux and, compared to ABCA1 KO transplanted mice, elevated serum total cholesterol levels. Importantly, these mice also suffer from enhanced systemic and hepatic

  16. TRAIL deficiency contributes to diabetic nephropathy in fat-fed ApoE-/- mice.

    Full Text Available BACKGROUND: We recently demonstrated that TNF-related apoptosis-inducing ligand (TRAIL is protective of diet-induced diabetes in mice. While TRAIL has been implicated in chronic kidney disease, its role in vivo in diabetic nephropathy is not clear. The present study investigated the role of TRAIL in the pathogenesis of diabetic nephropathy using TRAIL(-/-ApoE(-/- mice. METHODS: TRAIL(-/-ApoE(-/- and ApoE(-/- mice were fed a high fat diet for 20 w. Plasma glucose and insulin levels were assessed over 0, 5, 8 and 20 w. At 20 w, markers of kidney function including creatinine, phosphate, calcium and cystatin C were measured. Changes in mRNA expression of MMPs, TIMP-1, IL-1β and IL-18 were assessed in the kidney. Functional and histological changes in kidneys were examined. Glucose and insulin tolerance tests were performed. RESULTS: TRAIL(-/-ApoE(-/- mice had significantly increased urine protein, urine protein:creatinine ratio, plasma phosphorous, and plasma cystatin C, with accelerated nephropathy. Histologically, increased extracellular matrix, mesangial expansion and mesangial cell proliferation in the glomeruli were observed. Moreover, TRAIL(-/-ApoE(-/- kidneys displayed loss of the brush border and disorganisation of tubular epithelium, with increased fibrosis. TRAIL-deficient kidneys also had increased expression of MMPs, TIMP-1, PAI-1, IL-1β and IL-18, markers of renal injury and inflammation. Compared with ApoE(-/- mice, TRAIL-/-ApoE-/- mice displayed insulin resistance and type-2 diabetic features with reduced renal insulin-receptor expression. CONCLUSIONS: Here, we show that TRAIL-deficiency in ApoE(-/- mice exacerbates nephropathy and insulin resistance. Understanding TRAIL signalling in kidney disease and diabetes, may therefore lead to novel strategies for the treatment of diabetic nephropathy.

Naturally acquired microchimerism develops throughoutpregnancy, as a consequence of the clearly demonstrated bidirectional transplacental traffic of cells. This transference results in a long-term postpartum microchimeric state for both, the mother (fetal microchimerism and her progeny (maternal microchimerism. Furthermore, the establishment of this condition occurs, iatrogenically, after organ transplantation and blood transfusions. Microchimerism is subject of current interest worldwide, given its multiple possible implications for health and disease. Initial investigation was promoted because of its potential for the development of new techniques in noninvasive prenatal diagnosis, nowadays its feasible utility for stem cell therapy is being explored. Hypotheses propose that microchimerism could be involved in the pathogenesis of some autoimmune diseases, tissue repair, cancer and tolerance induction.

The accumulation of significant amounts of radwaste at RRC KI territory is shown to be the inevitable result of Institute&apos;s activity performed in the days of former USSR nuclear weapons project and multiple initial nuclear power projects (performed from 1950&apos;s to early 1970&apos;s). A characterization of RRC KI temporary radwaste disposal site is given. Described is the system of radiation control and monitoring as implemented on this site. A potential hazard of adverse impacts on the environment and population of the nearby housing area is noted, which is due to possible spread of the radioactive plume by subsoil waters. A description of the concept and project of the RRC KI temporary radwaste disposal site is presented. Specific nature of the activities planned and performed stems from the nearness of housing area. This paper describes main stages of the planned activities for rehabilitation, their expected terms and sources of funding, as well as current status of the project advancement. Outlined are the problems faced in the performance and planning of works. The latter include: diagnostics of the concrete-grouted repositories, dust-suppression technologies, packaging of the fragmented ILW and HLW, soil clean-up, radioactive plume spread prevention, broad radiation monitoring of the work zone and environment in the performance of rehabilitation works. Noted is the intention of RRC KI to establish cooperation with foreign, first of all, the U.S. partners for the solution of problems mentioned above.

    ApoliopoproteinE Ɛ4 (ApoE-Ɛ4) polymorphism is the most well known genetic risk factor for developing Alzheimers Disease. The exact mechanism through which ApoE 4 increases AD risk is not fully known, but may be related to decreased clearance and increased oligomerization of Aβ. By making measurements of white matter integrity via diffusion MR and correlating the metrics in a voxel-based statistical analysis with ApoE-Ɛ4 genotype (whilst controlling for vascular risk factor, gender, cognitive status and age) we are able to identify changes in white matter associated with carrying an ApoE Ɛ4 allele. We found potentially significant regions (Puncorrected < 0:05) near the hippocampus and the posterior cingulum that were independent of voxels that correlated with age or clinical dementia rating (CDR) status suggesting that ApoE may affect cognitive decline via a pathway in dependent of normal aging and acute insults that can be measured by CDR and Framingham Coronary Risk Score (FCRS).

    Among the numerous different pathological conditions summarised under the popular slogan &apos;Waldsterben&apos;, the &apos;acute yellowing&apos; of Norway spruce is the best defined syndrom. It is characterised by the yellowing of the older needle seasons, while the youngest shoots remain green until flushing in the following spring. The syndrom is restricted to soils with low Mg supply originating from silicate rocks. In this study, the dynamics of the disease was investigated over a period of 3 years by following the course of the disease in individual about 40 years old trees and by mapping more than thousand young trees in two plots with natural regeneration (Bavarian Forest; Spiegelhuette I and II) which exhibited the onset of the disease followed by a distinct spontaneous recovery of part of the population. The following results were obtained: Yellowing of the needles is accompanied by a decrease in Mg and pigment content. During pigment reduction the normal chlorphyll: carotene ratio remains almost unchanged, thus resembling the metabolically regulated pigment reduction in sun leaves rather than the direct photooxidative pigment destruction involving ozone. The latter would lead to a predominant decrease in carotene. &apos;Acute yellowing&apos; causes a reduction of annual increment by about 30%, while mortality is low. All phases of &apos;acute yellowing&apos; - onset, progression, stagnation, regreening - occurred in the same stands at the same time. In some cases, even neighbouring trees with overlapping root systems showed a contrary development of the disease.

    Apolipoprotein D (Apo D) and Apolipoprotein J (Apo J) are among the only nine apolipoproteins synthesized in the nervous system. Apart from development, these apolipoproteins are implicated in the normal aging process as well as in different neuropathologies as Alzheimer's disease (AD), where a neuroprotective role has been postulated. Different authors have proposed that Apo D and Apo J could be biomarkers for AD but as far as we know, there are no studies about the relationship between them as well as their expression pattern along the progression of the disease. In this paper, using double immunohistochemistry techniques, we have demonstrated that Apo D is mainly located in glial cells while Apo J expression preferentially occurs in neurons; both proteins are also present in AD diffuse and mature senile plaques but without signal overlap. In addition, we have observed that Apo J and Apo D immunostaining shows a positive correlation with the progression of the disease and the Braak's stages. These results suggest complementary and cell-dependent neuroprotective roles for each apolipoprotein during AD progress.

    The paper defines, describes, and presents the &apos;P&apos; curves for micro-structural characterization of the complex fluids, complex powders, and complex solid matrix, having magnetic properties. P curves are the first derivative (relative to the magnetic field strength) of the hysteresis curves relative to the saturation magnetization. They offer the possibility to investigate live biological materials without sample extraction.

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

    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

  10. The &apos;symplectic camel principle&apos; and semiclassical mechanics

    We propose a theory of semiclassical mechanics in phase space based on the notion of quantized symplectic area. The definition of symplectic area makes use of a deep topological property of symplectic mappings, known as the &apos;principle of the symplectic camel&apos; which places stringent conditions on the global geometry of Hamiltonian mechanics. Following this principle, symplectic mappings - and hence Hamiltonian flows - are much more rigid than Liouville&apos;s theorem suggests. The dynamical objects of our semiclassical theory are &apos;waveforms&apos;, whose definition requires the notion of square root of de Rham forms. The arguments of these square roots are calculated by using the properties of a generalized Maslov index. The motion of waveforms is determined by Hamiltonian mechanics, and the local expressions of these moving waveforms on configuration space are the usual approximate solutions of WKB-Maslov theory.

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) presents the results of a project that examined the power consumption of a &apos;smart home&apos; - a single-family dwelling in Chur, Switzerland. The house&apos;s power consumption is compared with that of a similar dwelling in 1992. The report describes the preparatory work for the project and analyses the power requirements of the various electrical consumers in the house. Comparisons are made with the electricity consumption of an average Swiss house. Possibilities of increasing efficiency are looked at. Consumption is extrapolated to national level on the basis of previous studies. A comprehensive appendix with details on the house&apos;s usage, its inhabitants&apos; needs, its multimedia concept and its technical equipment completes the report.

    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.

    Full Text Available APOE ε4 (apoE4 polymorphism is the main genetic determinant of sporadic Alzheimer’s disease (AD. A dietary approach (Fortasyn including docosahexaenoic acid, eicosapentaenoic acid, uridine, choline, phospholipids, folic acid, vitamins B12, B6, C, and E, and selenium has been proposed for dietary management of AD. We hypothesize that the diet could inhibit AD-like pathologies in apoE4 mice, specifically cerebrovascular and connectivity impairment. Moreover, we evaluated the diet effect on cerebral blood flow (CBF, functional connectivity (FC, gray/white matter integrity, and postsynaptic density in aging apoE4 mice. At 10–12 months, apoE4 mice did not display prominent pathological differences compared to wild-type (WT mice. However, 16–18-month-old apoE4 mice revealed reduced CBF and accelerated synaptic loss. The diet increased cortical CBF and amount of synapses and improved white matter integrity and FC in both aging apoE4 and WT mice. We demonstrated that protective mechanisms on vascular and synapse health are enhanced by Fortasyn, independent of apoE genotype. We further showed the efficacy of a multimodal translational approach, including advanced MR neuroimaging, to study dietary intervention on brain structure and function in aging.

    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

    Sterol 27-hydroxylase (CYP27A1) is involved in bile acid synthesis and cholesterol homoeostasis. Cyp27a1((-/-))/Apolipoprotein E((-/-)) double knockout mice (DKO) fed a western diet failed to develop atherosclerosis. Caveolin-1 (CAV-1), the main component of caveolae, is associated with lipid homoeostasis and has regulatory roles in vascular diseases. We hypothesized that liver CAV-1 would contribute to the athero-protective mechanism in DKO mice. Cyp27a1((+/+))/ApoE((-/-)) (ApoE KO), Cyp27a1((+/-))/ApoE((-/-)) (het), and DKO mice were fed a western diet for 2 months. Atherosclerotic plaque and CAV-1 protein were quantified in aortas. Hepatic Cav-1 mRNA was assessed using qPCR, CAV-1 protein by immunohistochemistry and western blotting. Total hepatic and plasma cholesterol was measured using chemiluminescence. Cholesterol efflux was performed in RAW264.7 cells, using mice plasma as acceptor. CAV-1 protein expression in aortas was increased in endothelial cells of DKO mice and negatively correlated with plaque surface (P < 0.05). In the liver, both CAV-1 protein and mRNA expression doubled in DKO, compared to ApoE KO and het mice (P < 0.001 for both) and was negatively correlated with total hepatic cholesterol (P < 0.05). Plasma from DKO, ApoE KO and het mice had the same efflux capacity. In the absence of CYP27A1, CAV-1 overexpression might have an additional athero-protective role by partly overcoming the defect in CYP27A1-mediated cholesterol efflux.

    The relevance of serum apolipoprotein E (apoE) levels to two hypertriglyceridemic dyslipidemias has not been clarified. We explored, in a cross-sectional (and short-term prospective) evaluation, the independent relationship of serum apoE to the atherogenic dyslipidemia, hypertriglyceridemia with elevated apoB (HtgB) and to apoA-I dysfunctionality, previously shown in Turkish adults to be independent of apoE genotype. Serum apoE concentrations were measured by immunonephelometry in 1,127 middle-aged adults. In multivariable regression analysis, apoE concentrations showed log-linear associations with apoB and apoA-I levels, waist circumference, independent of C-reactive protein (CRP), homeostatic model assessment (HOMA) index and other confounders. The likelihood of atherogenic dyslipidemia and of HtgB roughly tripled per 1-SD increment in apoE concentrations, additively to apoE genotype, HOMA, apoA-I, CRP concentrations and waist circumference; yet apoA-I, protective against atherogenic dyslipidemia, appeared to promote HtgB, a finding consistent with apoA-I dysfunctionality in this setting. Each 1-SD increment in the apoE level was moreover, associated in both genders with MetS (at OR 1.5), after adjustment for sex, age, apoB, apoA-I and CRP, or for apoE genotypes. Circulating apoE predicted in both genders age-adjusted prevalent and incident coronary heart disease (CHD), independent of apoE genotype and CRP (OR 1.32 [95 % CI 1.11; 1.58]). To conclude, in a general population prone to MetS, elevated apoE concentrations are strongly linked to HtgB and atherogenic dyslipidemia, irrespective of apoE genotype, are associated with MetS and CHD. Excess apoE reflects pro-inflammatory state and likely autoimmune activation.

No evidence for these decays has been found. Assuming uniform three-body phase space distributions for the D-ℓ+ℓ&apos;+ decays, we set the following upper limits on the branching fractions at 90% confidence level: B(B+ D-e+e+) < 2.6×10-6, B(B+ D-e+μ+) < 1.8 × 10-6 and B(B+ D-μ+μ+) < 1.0 × 10-6.
