  12. Workshop Arboretum Volčji potok

    Directory of Open Access Journals (Sweden)

    Ana Kučan

    2012-01-01

    Full Text Available From its constitution onwards, the Volčji Potok Arboretum has been caught between various conflicting orientations. It is both a scientific, research and educational institution, and a cultural monument with exquisite garden and landscape design features and areas of great natural value and built cultural heritage, as well as commercial venue. At the same time, it functions as a park and an area for mass events, a garden centre and nursery. This variety of functions has helped Arboretum to survive the pressures of time; however, partial and uncoordinated interventions have threatened its original mission and its image and generated a number of conflicting situations. The workshop, organised on the initiative of the Institute for the Protection of Cultural Heritage of Slovenia, which involved students from the Faculty of Architecture and students from the Department of Landscape Architecture of the Biotechnical Faculty in mixed groups, generated eight proposals to solve some of the most urgent problems by introducing optimised development with clearly defined goals and priorities.

  13. Chile menos volátil

    Directory of Open Access Journals (Sweden)

    Felipe Larraín B.

    2008-01-01

    Full Text Available Desde fines de 1998 la economía chilena se desaceleró mucho. Si entre 1988 y 1998 la tasa de crecimiento promedio alcanzó un 7.8%, durante el período postcrisis asiática fue de sólo un 3.7%. Sin embargo, junto con la desaceleración del crecimiento, la volatilidad de la economía se redujo prácticamente a la mitad.Este trabajo investiga, mediante un análisis empírico formal, el papel que tuvieron la introducción de la flotación cambiaria y la utilización de la regla de superávit estructural en transformar a Chile en una economía menos volátil. Nuestros resultados muestran que la introducción de la regla fiscal parece haber reducido en un tercio la volatilidad del crecimiento del PIB. Por su parte, la flotación cambiaria contribuyó a reducir esa volatilidad adicionalmente en alrededor de un cuarto. Así, en conjunto, ambas medidas aparecen como responsables de haber disminuido la volatilidad del crecimiento de la economía chilena en casi 60%. Estos resultados son robustos ante especificaciones y posibles problemas de endogeneidad en algunas de las variables explicativas.

  18. Isothermal reduction kinetics of Panzhihua ilmenite concentrate under 30vol% CO-70vol% N2 atmosphere

    Science.gov (United States)

    Zhang, Ying-yi; Lü, Wei; Lü, Xue-wei; Li, Sheng-ping; Bai, Chen-guang; Song, Bing; Han, Ke-xi

    2017-03-01

    The reduction of ilmenite concentrate in 30vol% CO-70vol% N2 atmosphere was characterized by thermogravimetric and differential thermogravimetric (TG-DTG) analysis methods at temperatures from 1073 to 1223 K. The isothermal reduction results show that the reduction process comprised two stages; the corresponding apparent activation energy was obtained by the iso-conversional and model-fitting methods. For the first stage, the effect of temperature on the conversion degree was not obvious, the phase boundary chemical reaction was the controlling step, with an apparent activation energy of 15.55-40.71 kJ·mol-1. For the second stage, when the temperatures was greater than 1123 K, the reaction rate and the conversion degree increased sharply with increasing temperature, and random nucleation and subsequent growth were the controlling steps, with an apparent activation energy ranging from 182.33 to 195.95 kJ·mol-1. For the whole reduction process, the average activation energy and pre-exponential factor were 98.94-118.33 kJ·mol-1 and 1.820-1.816 min-1, respectively.

    Problems such as global warning, air pollution centering mainly to big cities, diversification of energy resources and so forth are dealt world widely in big scale and expectation to clean electric vehicles is getting higher. Conventional electric vehicles were mainly light vans. Although the ZEV sale compulsion from the year 1998 in California State was postponed, small type electric vehicles with improved performance appeared one after another from the fact that there is 10% sale compulsion in 2003. In Japan, these ordinary/small type electric vehicles are getting popularized rapidly. As for overseas, present record of 1996, number of electric vehicles sold by America were 2300 cars, Europe sold 3000 cars, Italy 800 cars, Germany 4,500 cars, Switzerland 2,050 cars and their sale has been promoted centering to France. As for technology development, transfer from direct motor to alternating motor as a power unit is completely ahead. Further, development of new type of battery is commonly carried out and electric vehicles with new battery are outstanding. 4 refs., 5 figs., 4 tabs.

    The effect of steel fiber (SF) addition to concrete on the corrosion behavior of steel reinforcement was studied by immersion corrosion tests in a 3 mass % NaCl solution for 363 day. The tests were conducted on steel rod/mortar specimens with different SF content (0-2 vol %), and corrosion potentials and electrochemical impedance of the specimens were measured during the tests. Corrosion potentials of the specimens were not so changed by the SF content. Electrochemical impedance measured at corrosion potentials was analyzed to get charge transfer resistance (R{sub ct}) using an equivalent electrical circuit with the R{sub ct}, Warburg impedance and a constant-phase element. The corrosion rate of steel rod in mortar estimated from the reciprocal of the R{sub ct} decreased with increasing of SF content in mortar, and correlated well with the rust area of steel rod measured after immersion corrosion tests. This shows that the electrochemical impedance measurement is the useful diagnosis method of corrosion of steel in concrete. The corrosion inhibition of steel rod in mortar by the SF addition was thought to be attributed to the consumption of dissolved oxygen by the corrosion of SF in mortar. (author)

    Full Text Available The amount of medical image data produced in clinical and research settings is rapidly growing resulting in vast amount of data to analyze. Automatic and reliable quantitative analysis tools, including segmentation, allow to analyze brain development and to understand specific patterns of many neurological diseases. This field has recently experienced many advances with successful techniques based on non-linear warping and label fusion. In this work we present a novel and fully automatic pipeline for volumetric brain analysis based on multi-atlas label fusion technology that is able to provide accurate volumetric information at different levels of detail in a short time. This method is available through the volBrain online web interface (http://volbrain.upv.es, which is publically and freely accessible to the scientific community. Our new framework has been compared with current state-of-the-art methods showing very competitive results.

    Full Text Available Welcome to the first appearance of PORTAL for 2006 (vol. 3, no. 1, a special issue entitled ‘Other Worlds’ guest edited by James Goodman and Christina Ho from the Faculty of Humanities and Social Sciences, University of Technology Sydney (UTS. The papers collected in this special issue focus on what the guest editors call “the transformative power of social movements” that respond to the processes and discourses of globalization and globalism by generating alternative sites and spaces of agency, or ‘other worlds.’ The contributors to the issue originally presented papers at a conference held in April 2005 in Sydney, with the title ‘Other Worlds: Social Movements and the Making of Alternatives.’ That conference was organized by the Research Initiative on International Activism at UTS, and supported by the Research Committee on Social Movements and Collective Action of the International Sociological Association. The Editorial Committee of PORTAL would like to thank both institutions for their support of the event that led to this special issue. I would also like to thank Wayne Peake, Kate Barclay, and Murray Pratt for their editorial efforts in seeing this issue through to publication. The Editorial Committee is pleased to showcase in the Cultural Works Section a short meditative piece by local writer Joel Scott, who is currently undertaking studies in Pamplona, Spain. When considered in the context of the special issue’s discussions of ‘other worlds’ that precede it, Scott’s ‘God, We’re Not Immigrants! A Reflection on Moving and Staying,’ provides an evocative insight into the sociocultural and imaginative limits that may preclude the construction of alternative ‘worlds.’

  4. Introduction of electric double layer capacitors in the solar-EV; Solar denki jidosha eno denki nijuso condenser no oyo

    Energy Technology Data Exchange (ETDEWEB)

    Fujinaka, M. [Tokyo Denki University, Tokyo (Japan)

    1996-10-27

    A basic experiment was carried out on a supplementary power supply, in which solar cells and electric double layer capacitors(EDLC) were combined for a DC/DC converter, for the use of a solar-electric vehicle (S-EV); and in actuality, an S-EV was loaded with the power supply with a running test conducted on a public road. The EDLC was found effective and useful for avoiding temporary lowering of voltage and momentary break. An electric supply was thereby made possible for an emergency light without the use of the DC/DC converter. However, in a tunnel or a night driving and in case of failure of the DC/DC converter, an operating time of only 7 minutes or so was affordable with the EDLC having a capacity of 100F. Moreover, particularly with a heavy load, it was impossible to maintain a voltage for many hours. Under the circumstances, an S-EV design would primarily require two sets of independent DC/DC converter loaded in the future. The EDLC, young after it was developed, still has a small energy density compared with a lead storage battery. Yet, an EDLC with a higher performance being developed, there is a possibility that it will be applied to S-EV`s by utilizing its characteristics such as a high efficiency and a long service life. 4 refs., 8 figs.

    Full Text Available Embora pareça existir um "flavor" característico de mel, a grande variedade de flores disponíveis para a abelha, possibilita uma grande diversidade de flavor e aroma, indicando a presença de vários componentes voláteis. Alguns destes dependem da fisiologia da abelha, dos procedimentos após a colheita e no mel de melato há também a interferência de insetos sugadores e das formigas. Várias substâncias voláteis já foram identificadas, sendo algumas características de determinados méis uniflorais. Com o objetivo de encontrar uma substância volátil característica do mel de melato, seis amostras deste tipo de mel e seis amostras de mel floral foram analisadas usando extração por arraste de gás hidrogênio e cromatografia a gás acoplada a espectrometria de massas. Ácido acético foi encontrado em quatro amostras de mel de melato e em uma amostra de mel floral porém, com menor abundância.

The study has found that the significant intergenerational differences exist in educa- tion levels and employment, which exerts significant influence on family migration behavior. On the other side, there is no significant difference in influential factors on family migration as residence time, the fam- ily income in immigrant city, remittance between two generations of floating population, in which the in- tergenerational consistency is noticeable.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Em pacientes não obstétricas, demonstrou-se que a expansão volêmica rápida realizada imediatamente após a injeção subaracnóidea do anestésico local era mais efetiva que a expansão volêmica lenta, realizada previamente à instalação do bloqueio para se reduzir a incidência e a gravidade da hipotensão arterial após raquianestesia. O objetivo do estudo foi comparar a incidência de hipotensão arterial e o consumo de vasopressores em gestantes submetidas à cesariana sob raquianestesia com diferentes regimes de expansão volêmica. MÉTODO: Foram avaliadas prospectivamente 60 gestantes de termo submetidas à cesariana sob raquianestesia. As pacientes receberam expansão volêmica com 10 ml.kg-1 de solução de Ringer com lactato como segue: Grupo 1 (n = 20, antes da raquianestesia através de cateter 18G; Grupo 2 (n = 20, após a raquianestesia e com cateter 18G e Grupo 3 (n = 20 após a raquianestesia com cateter 16G sob ação de pressurizador. A pressão arterial (PA foi monitorizada a cada minuto e administrou-se 0,2 mg de metaraminol para qualquer diminuição de PA, a partir do valor de controle e 0,4 mg para diminuição > 20%. A PA controle foi definida como a média de três valores sucessivos de pressão arterial sistólica obtidos antes da expansão volêmica e do bloqueio. Estudou-se a velocidade de infusão de fluidos, incidência de hipotensão arterial materna, náusea e vômito, consumo de metaraminol, índice de Apgar e pH da artéria umbilical. RESULTADOS: A velocidade de administração de fluidos foi maior no Grupo 3 do que nos Grupos 1 e 2 (201 ± 61 vs 56 ± 13 e 59 ± 21 ml.min-1, p < 0,05. Os grupos foram semelhantes em relação à incidência de hipotensão arterial, náusea, vômito, consumo de metaraminol, índice de Apgar e pH da artéria umbilical.

    Energy Technology Data Exchange (ETDEWEB)

    Max, C.E.

    1981-12-01

    This monograph deals with the physics of the coronal region in laser fusion targets. The corona consists of hot plasma which has been evaporated from the initially solid target during laser heating. It is in the corona that the laser light is absorbed by the target, and the resulting thermal energy is conducted toward cold high-density regions, where ablation occurs. The topics to be discussed are theoretical mechanisms for laser light absorption and reflection, hot-electron production, and the physics of heat conduction in laser-produced plasmas. An accompanying monograph by H. Ahlstrom (Vol.II) reviews the facilities, diagnostics, and data from recent laser fusion experiments.

  9. Reposição volêmica em pacientes politraumatizados

    Full Text Available O debate sobre a administração de colóides, cristalóides, soluções hipertônicas ou elementos sanguíneos em pacientes críticos estende-se desde o século 19. Algumas dessas soluções podem ser diferentemente distribuídas nos espaços intra e extravasculares, assim como nos espaços intra e extracelulares, causando diferentes efeitos fisiológicos. Diversos estudos foram realizados com o objetivo de comparar um fluido ao outro, mostrando a eficácia e as vantagens de cada um. Porém, não existe um trabalho que consiga provar uma diferença significativa em relação à morbi-mortalidade após a reposição volêmica com cada tipo de fluido. Esses estudo, por serem diferentes em relação aos protocolos de ressucitação, volumes e tipos de fluidos utilizados, dificultam a comparação dos resultados; no entanto, sabe-se que a reposição volêmica depende de cada situação clínica. A utilização da reposição volêmica pré-hospitalar é discutível, visto que pode aumentar o sangramento ou mesmo ser motivo de atraso na transferência do paciente ao hospital, ao mesmo tempo em que pode reduzir o risco de isquemia tecidual. Uma vez que a hemorragia tenha sido controlada, há um consenso para o fato de que o volume intravascular deve ser reposto da forma mais rápida e eficaz possível para minimizar a quantidade de células afetadas diretamente pela má perfusão tecidual. Os atuais trabalhos envolvidos nessa polêmica trazem resultados que sugerem a continuidade das investigações, visto que nenhum deles atingiu um ponto final comum. Desses estudos, um aspecto com o qual todos concordam e que se tornou claro é que não existe uma fórmula mágica única de administração intravenosa para os pacientes politraumatizados. Este trabalho visa, por meio de revisão bibliográfica, mostrar os tipos de fluidos a serem utilizados para reposição volêmica de pacientes politraumatizados, assim como os meios e a forma de utilização dos

    Abstract : The practical logic of Vol. 4 of ' Das Kapital' is the cognitive development mechanism of category of ' Das Kapital' In this sense, this logic makes the ' production' of categories practical, the dominant principle is that understanding is made of history. Historical part and theoretical part construct the general writing logic togeth-er, historical part sets up theoretical direction for research afterwards. The implications are of the following: (1) Based on ' organic growth' of historical productive mode, the core of the category is surplus value ; (2) From the movement of category production to disclose historical structural growth ; ( 3 ) Through the general ' production' of theories, it shows the internal integration between critique on methodology and critique on epistemology. Thus Vol. 4 of ' Das Kapital' rejected the wrong demand in ' History of the Theory of Surplus Value' edited by Kautsky. ' Das Kapital' integrated the logic of historical development and the logic of development in understanding, inte-grated historical method and categorical method, which sets an example in the methodology in political economy.%Abstract : The practical logic of Vol. 4 of ' Das Kapital' is the cognitive development mechanism of category of ' Das Kapital' In this sense, this logic makes the ' production' of categories practical, the dominant principle is that understanding is made of history.

    Antiviral quinolones are promising compounds in the search for new therapeutically effective agents for the treatment of AIDS. To rationalize the SAR for this new interesting class of anti-HIV derivatives, we performed a 3D-QSAR study on a library of 101 6-fluoro and 6-desfluoroquinolones, taken either from the literature or synthesized by us. The chemometric procedure involved a fully semiempirical minimization of the molecular structures by the AMSOL program, which takes into account the solvatation effect, and their 3D characterization by the VolSurf/GRID program. The QSAR analysis, based on PCA and PLS methods, shows the key structural features responsible for the antiviral activity.

    Full Text Available In this paper, we give an elementary proof of the result that the minimal volumes of R³ and R4 are zero. The approach is to construct a sequence of explicit complete metrics on them such that the sectional curvatures are bounded in absolute value by 1 and the volumes tend to zero. As a direct consequence, we get that MinVol (Rn = 0 for n > 3.Neste artigo fornecemos uma demonstração elementar do resultado de que os volumes minimais de R³ e R4 são ambos iguais a zero.

    Full Text Available En este trabajo se aplican y se extienden los patrones de evolución de filiales planteados por Birkinshaw y Hood, al estudiar la influencia de los entornos volátiles sobre los procesos de evolución de las filiales de empresas multinacionales. Utilizando una metodología cualitativa a través de 41 estudios de casos de filiales de diversos sectores localizadas en Venezuela, se observó que las mismas siguen procesos conducentes a la mejora, el refuerzo y al declive de sus roles. En los resultados se identifican a la matriz y la propia filial como impulsores de esos procesos, pero se aprecia también al entorno local como determinante de la evolución de las filiales, con lo cual se extienden los patrones que plantean Birkinshaw y Hood que consideran sólo a la matriz y a la propia filial. Como conclusión, no sólo se resalta la importancia del entorno en la determinación del rol de las filiales, sino que se evidencia que los entornos volátiles pueden tener un impacto tanto positivo como negativo en la evolución de la filial.

    Full Text Available Antjie Krog’s translation of Henk van Woerden’s novel Een mond vol glas (A mouth full of glass Against a historical backdrop several critical approaches to translational theory are explicated. Traditional criticism seems to imply positioning between the Source Text (ST and the Target Text (TT. A functionalist approach (as propagated among others by Snell-Hornby, Nord and Naaijkens is a descriptive rather than a normative approach that focuses almost exclusively on the ST. This approach is consequently adopted in the evaluation of Krog’s translation; yet even within this more relativistic paradigm, a comparison between ST and TT should not be evaded. In the case of Krog’s translation, this comparison leads to the identification of scores of lexical, grammatical and stylistic errors.

    To compare hepatic parenchymal contrast media (CM) enhancement during multi-detector row computed tomography (MDCT) and its correlation with volume pitch-corrected computed tomography dose index (CTDI{sub vol}) and body weight (BW). One hundred patients referred for standard three-phase thoraco-abdominal MDCT examination were enrolled. BW was measured in the CT suite. Forty grams of iodine was administered intravenously (iodixanol 320 mg I/ml at 5 ml/s or iomeprol 400 mg I/ml at 4 ml/s) followed by a 50-ml saline flush. CTDI{sub vol} presented by the CT equipment during the parenchymal examination was recorded. The CM enhancement of the liver was defined as the attenuation HU of the liver parenchyma during the hepatic parenchymal phase minus the attenuation in the native phase. Liver parenchymal enhancement was negatively correlated to both CTDI{sub vol} (r = -0.60) and BW (r = -0.64), but the difference in correlation between those two was not significant. CTDI{sub vol} may replace BW when adjusting CM doses to body size. This makes it potentially feasible to automatically individualize CM dosage by CT. (orig.)

    One of the challenges in tomography is the availability of suitable software for image processing and analysis in 3D. We present here 'tomo_display' and 'vol_tools', two packages created in IDL that enable reconstruction, processing, and visualization of tomographic data. They complement in many ways the capabilities offered by Blob3D (Ketcham 2005 - Geosphere, 1: 32-41, DOI: 10.1130/GES00001.1) and, in combination, allow users without programming knowledge to perform all steps necessary to obtain qualitative and quantitative information using tomographic data. The package 'tomo_display' was created and is maintained by Mark Rivers. It allows the user to: (1) preprocess and reconstruct parallel beam tomographic data, including removal of anomalous pixels, ring artifact reduction, and automated determination of the rotation center, (2) visualization of both raw and reconstructed data, either as individual frames, or as a series of sequential frames. The package 'vol_tools' consists of a series of small programs created and maintained by Guilherme Gualda to perform specific tasks not included in other packages. Existing modules include simple tools for cropping volumes, generating histograms of intensity, sample volume measurement (useful for porous samples like pumice), and computation of volume differences (for differential absorption tomography). The module 'vol_animate' can be used to generate 3D animations using rendered isosurfaces around objects. Both packages use the same NetCDF format '.volume' files created using code written by Mark Rivers. Currently, only 16-bit integer volumes are created and read by the packages, but floating point and 8-bit data can easily be stored in the NetCDF format as well. A simple GUI to convert sequences of tiffs into '.volume' files is available within 'vol_tools'. Both 'tomo_display' and 'vol_tools' include options to (1) generate onscreen output that allows for dynamic visualization in 3D, (2) save sequences of tiffs to disk

    The prediction of human intestinal absorption is a major goal in the design,optimization,and selection of candidates for the develoment of oral drugs.In this study,a computerized method(VolSurf with GRID) was used as a novel tool for predicting human intestinal absorption of test compound,and for determining the critical molecular properties needed for human intestinal absorption.The tested molecules consisted of 20 diverse drug-like compounds.Partial least squares(PLS) discriminant analysis was used to correlate the experimental data with the theoretical molecular properties of human intestinal absorption.A good correlation(r2=0.95,q2=0.86) between the molecular modeling results and the experimental data demonstrated that human intestinal absorption could be predicted from the three-dimensional(3D) molecular structure of a compound .Favorable structureal properties identified for the potent intestinal absorption of drugs included strong imbalance between the center of mass of a molecule and the barycentre of its hydrophilic and hydrophobic regions and a definitive hydrophobic region as well as less hydrogen bonding donors and acceptors in the molecule.

Much better properties showed powders homogenized under basic conditions. They give dense materials composed of YAG inclusions within alumina matrix. YAG particles resulted from the reaction of Y2O3 with Al2O3 during heat treatment. Homogenization of the system mixed at pH=8, corresponding to the heterofloculation conditions, is slightly better than observed at pH=10. YAG inclusions (20 vol% increase hardness and fracture toughness of the material in comparison with pure alumina polycrystals.

    Magnesium matrix composite is one of the advanced lightweight materials with high potential to be used in automotive and aircraft industries due to its low density and high specific mechanical properties. The magnesium composites can be fabricated by adding the reinforcements of fibers or/and particles. In the previous literature, extensive studies have been performed on the development of matrix grain structure of aluminum-based metal matrix composites. However, there is limited information available on the development of grain structure during the solidification of particulate-reinforced magnesium. In this work, a 5 vol.% SiCp particulate-reinforced magnesium (AM50A) matrix composite (AM50A/SiCp) was prepared by stir casting. The solidification behavior of the cast AM50A/SiCp composite was investigated by computer-based thermal analysis. Optical and scanning electron microscopies (SEM) were employed to examine the occurrence of nucleation and grain refinement involved. The results indicate that the addition of SiCp particulates leads to a finer grain structure in the composite compared with the matrix alloy. The refinement of grain structure should be attributed to both the heterogeneous nucleation and the restricted primary crystal growth.

    Aluminium (Al) alloys are widely used in various industries, such as automotive and aerospace. The production processes in these sectors create large amount of Al residues. In this paper, a new method of recycling Al chip is presented. Metal matrix composite (MMCs) of Al-20 vol% Sn was prepared by using solid state direct conversion method of recycled Al 6061 alloy. Constant pressure (10 ton) was used to implement the cold forging process. The differences of sintering temperature (200 °C, 250 °C, 300 °C and 350 °C) and time intervals (1h, 2h, 3h, 4h and 5h) were studied to obtain the optimum hardness, strength and surface integrity of Al-20 vol% Sn. The results showed that, hardness and strength of Al-20 vol% Sn was decreased by additional temperature and increase with time interval of sintering. Sintering temperature at 350 °C produces better morphology structure of Al-Sn composites.

    The Computed Tomography (CT) is an important diagnostic imaging method, widely used. However, in spite of all the advantages and technologic advances within the CT scanners, the tomographic procedures result in high absorbed doses to patients. The main objective of this work was to perform a dosimetric study of CT scanners located at Recife and to evaluate the image quality on CT examinations in these equipment. The volume CT air kerma index (C{sub VOL}) and air kerma length product (P{sub KL,CT}) were estimated. These values were calculated using normalized weighted air kerma indexes in CT standard dosimetry phantoms ({sub n}C{sub W}), supplied by ImPACT group for several CT scanners, and the scan parameters of routine head, routine chest and hi-resolution chest CT exams performed at 20 institutions. The irradiation parameters of 15 adult patients for each CT procedure were registered at six participating centres, at which the phantom from the American College of Radiology (ACR) CT accreditation protocol was used for the image quality measurements. For routine head exams, the C{sub VOL} values varied between 12 and 58 mGy (at the posterior fossa) and 15 to 58 mGy (at the cerebrum) and the P{sub KL,CT}, from 150 to 750 mGy{center_dot}cm. The C{sub VOL} values for routine chest procedures varied from 3 to 26 mGy and the P{sub KL,CT}, between 120 and 460 mGy{center_dot}cm. In relation to Hi-resolution chest exams, C{sub VOL} values were from 1.0 to 2.7 mGy and the P{sub KL,CT} values varied between 24 and 67 mGy{center_dot}cm. The image quality evaluations results showed that almost all scanners presented at least one inadequacy. One of the equipment presented faults at 70% of the tests. With regard to the image noise, only two scanners presented acceptable results. From these results, it is possible to conclude that the volume CT air kerma index values are lower than the European reference levels. However, the image quality of these CT scanners does not attend the

    UDP-glucuronosyltransferase 2B7 (UGT2B7) is an important enzyme responsible for clearance of many drugs. Here, we report two 3D quantitative structure-activity relationship (QSAR) models for UGT2B7 using the pharmacophore and VolSurf approach, respectively. The dataset included 53 structurally diverse UGT2B7 substrates, 36 of which were used for the training set and 17 of which for the external test set. Pharmacophore-based 3D-QSAR model (or hypothesis) was developed using the Discovery Studio program. A user-defined "glucuronidation site" feature was forcefully included in a pharmacophore hypothesis. VolSurf-based 3D-QSAR model was generated using the VolSurf program. This involves calculation of VolSurf descriptors, variable selection with the FFD algorithm, and partial least squares (PLS) analyses. The best pharmacophore model (r(2) = 0.736) consists of one glucuronidation site, one hydrogen bond acceptor, and three hydrophobic regions. Using this model, K(m) values for 14 of 17 test substrates were predicted within one log unit. The yielded VolSurf (PLS) model with two components shows statistical significance in both fitting and internal predicting (r(2) = 0.866, q(2) = 0.728). Further, the K(m) values for all test substrates were predicted within one log unit. In addition, the VolSurf model reveals an overlay of chemical features influencing the enzyme-substrate binding. Those include molecular size and shape, integy moments, capacity factors, best volumes of DRY probe, H-bonding, and log P. In conclusion, the pharmacophore and VolSurf approaches are successfully utilized to establish predictive models for UGT2B7. The derived models should be an efficient tool for high throughput prediction of UGT2B7 metabolism.

    This handbook was prepared primarily with the aim to provide information to experts in industry, authorities or research facilities engaged in criticality-safety-related problems that will allow an adequate and rapid assessment of criticality safety issues already in the planning and preparation of nuclear facilities. However, it is not the intention of the authors of the handbook to offer ready solutions to complex problems of nuclear safety. Such questions have to remain subject to an in-depth analysis and assessment to be carried out by dedicated criticality safety experts. Compared with the previous edition dated December 1998, this handbook has been further revised and supplemented. The proven basic structure of the handbook remains unchanged. The handbook follows in some ways similar criticality handbooks or instructions published in the USA, UK, France, Japan and the former Soviet Union. The expedient use of the information given in this handbook requires a fundamental understanding of criticality and the terminology of nuclear safety. In Vol. 1, ''Criticality and Nuclear Safety'', therefore, first the most important terms and fundamentals are introduced and explained. Subsequently, experimental techniques and calculation methods for evaluating criticality problems are presented. The following chapters of Vol. 1 deal i. a. with the effect of neutron reflectors and absorbers, neutron interaction, measuring methods for criticality, and organisational safety measures and provide an overview of criticality-relevant operational experience and of criticality accidents and their potential hazardous impact. Vol. 2 parts 1 and 2 finally compile criticality parameters in graphical and tabular form. The individual graph sheets are provided with an initially explained set of identifiers, to allow the quick finding of the information of current interest. Part 1 includes criticality parameters for systems with {sup 235}U as fissile material, while part

    This paper describes three case studies for monitoring ground water aquifers by electrical prospecting. An example in the Hofu plain, Yamaguchi Prefecture is presented, where the ground water environment has been monitored for more than 30 years from the viewpoint of hydrology. Then, transition from the fresh ground water to sea water is evaluated by a sharp boundary as salt-water wedges through the field survey in a coastal area of a large city for a short term using vertical electrical prospecting. Moreover, streaming potential measurements are described to grasp the real-time behavior of ground water flow. From the long-term monitoring of ground water aquifer, it was found that the variation of ground water streaming can be evaluated by monitoring the long-term successive change in the resistivity of ground water aquifer. From the vertical electrical prospecting, water quality can be immediately judged through data analysis. From the results of streaming potential measurements and vertical electrical prospecting using Schlumberger method, streaming behavior of ground water in the area of spring water source can be estimated by determining three-dimensional resistivity structure. 17 refs., 15 figs.

    This paper views the industrial systems and devices at Fuji Electric. The year 1998 had business stagnation still continued, with capital investments for production increase having decreased sharply in the consumer field. On the other hand, investments increased in the areas of renewal, simplification, and man-power saving. Large rectifiers for aluminum refining and soda electrolysis gained a large amount of supply to overseas countries partly because of the effects from the foreign exchange market. In the technical aspect, demands have increased on opening and down-sizing of information and control devices in electrical installations for heavy industry fields, which led to increase in personal computer introduction. The heavy electric machine field has amalgamated more closely with the information and control fields. Fuji Electric has provided systems and devices that contribute to higher information density, reliability and functions of different plants. This paper introduces the record of the company in the fields of power electronics, electric power conversion, information devices and systems, speed variable driving systems, power generating and transforming systems, rotating machines, and electric heating.

    The paper reported on a Tokyo-Nagoya travel test on a practical spread type solar-electric vehicle, Solar-EV. A comparative study was made running the same type gasoline vehicle, GV. The measured power consumption amount of Solar-EV is 57.6 kWh. By converting it into Mcal unit, an energy consumption amount of 49.5 Mcal was obtained. Further, as to GV, the energy consumption amount of 316 Mcal was obtained using the amount of supply of gasoline (mean heating value: 8.4 Mcal/h) of 37.6 l and the fuel consumption of 16.2 km/l. Accordingly, the energy consumption amount of Solar-EV became a sixth of that of GV. In the cost comparison, the cost of Solar-EV was 1,440 yen (power source price: 25 yen/kWh), which is about a third of that of GV, 3760 yen (gasoline unit price: 100 yen/l). Monocrystal Si solar cells, 270W, installed on hood/roof are connected to the main 288V system (the auxiliary 12V system is amorphous Si), and generate power 4.4 kWh during travel. A total power consumption amount of Solar-EV in the total travel (Tokyo-Nagoya) is 79.9 kWh including the auxiliary system, approximately 6% of which was to be supplied from solar cells. 1 ref., 6 figs., 3 tabs.

    A report is made about the result of vertical electric sounding conducted in the MK district, Fukuoka City, where Kyushu University is about to move. As for the method of electrical prospecting, in consideration of the need for probing a depth of 50m at the shallowest, vertical electrical sounding with a Schlumberger array of electrodes was employed. Measurements were made for 57 locations on the planar ground, the interval between electrodes gradually increased from 1 to 200m. In the 2D structure model analysis, a 2D inversion program was utilized in the ABIC minimization method. Also investigated were the relationship of electric prospecting and the geology, geological conditions, water level in the well, water quality, salt water, and pore rate from the previously-conducted investigative boring. As the result, it was estimated that the boundary between the first and second layers detected by electric prospecting reflected the level of underground water and that the boundary between the second and third layers reflected the portion where the N-value sharply increases. 4 refs., 8 figs.

    For the enforcement of the {rho}a-{rho}u survey method which is a type of high-density electrical survey, a multichannel resistivity measuring instrument has been developed. This instrument, in addition to the above, conducts resistivity tomography and various other kinds of high-density electrical survey. A potential produced by a low frequency rectangular current of 1Hz or lower outputted by the transmitter of this instrument is received and measured by the receiver connected to electrodes positioned at 100 or less locations. The receiver comprises a scanner that automatically switches from electrode to electrode, conditioner that processes signals, and controller. A transmitter of the standard design outputs a maximum voltage of 800V and maximum current of 2A, making a device suitable for probing 50 to several 100m-deep levels.

    This paper introduces history of the development of an electric automobile, `Ecovehicle`. It is provided with a high overall energy efficiency compared with an engine vehicle. The Ecovihicle is 1.2m in width, 3.3m in length, 2 seating capacities and 910kg in overall weight with serially connected 56 batteries of each 4V, 40Ah and having the total weight of 269kg. Its travel distance per charging is 130km at a speed of 80 k.p.h. This vehicle is capable of running with an energy of approximately one third as much as that of a light car. In addition, the vehicle is provided with polycrystal solar batteries placed on 0.6m{sup 2} area on the roof and spoiler generating 60W maximum. Assuming the annual duration of sunshine is 1,800 hours, charging is possible for 63kWh annually. Assuming the charging efficiency is 83%, charging is possible about seven times, which is an equivalent of travelling about 1,000km annually. The characteristics for example are the employment of brushless DC motor, use of energy saving switching element IGBT in order to realize a low level of loss in the inverter, in-wheel motor system, and storage of storage batteries in a hollow aluminum frame installed under the floor. 2 refs., 5 figs., 1 tab.

    We developed simplified analysing method of C-11 PIB PET using a ligand and subject specific PET templates and evaluated the usefulness of this method by comparing standard MR-based methods in Alzheimer disease (AD). We studied 7 patients with AD (71.5{+-}11.5, M/F=3/4) and 5 normal controls (68.4{+-}8.9, M/F=1/4) with C-11 PIB PET and T1 MRI. 90-min dynamic PET scan was performed after injection of C-11 PIB (370 MBq). Region to cerebellar ratio image (ratio image) was obtained from 60-90 min image and distribution volume ratio image (DVR image) was obtained from 90-min dynamic image using a Logan graphical analysis. Ligand and subject specific PET templates were created by spatial normalization of MR coregistered ratio images of AD and normal group to T1 MR MNI template using SPM2. We compared the outcome of voxel based and automatic VOl analysis employing 3 parametric images: MR template based spatially normalized MR coregistered DVR image (MR-DVR image), MR template based normalized MR coregistered ratio image (MR-ratio image), AD and normal group specific PET template based normalized ratio image (PET-ratio image) in all subjects. Voxel based analyses using 3 parametric images revealed significantly increased PIB retention in several brain regions such as both orbitofrontal and temporoparietal cortices and posterior cingulated gyri of AD compared to normal (FDR<0.05), however, the z-values of these regions were more higher in PET- and MR-ratio images than in MR-DVR image. Automatic VOl analyses using 3 parametric images also revealed significantly increased PIB retention values in same regions of AD (p<0.05). PIB retention values in PET-ratio images were significantly correlated with those in MR-ratio images (R=0.96, slope=0.99, p<0.001) and also MR-DVR images (R=0.95, slope = 1.8, p<0.001). Voxel based and automatic VOl analysis can be simply and accurately performed in a single static C-11 PIB PET image using a ligand and subject specific PET templates

    Full Text Available There has been a growing interest in the food industry and in preventive medicine to search for «natural antioxidants». Therefore the objetive of this study was to evaluate the antioxidant activity of the non-volatile residue of essential orange oil in the oxidation of unrefined and freshly extracted olive oil. Essential orange oil was distilled to obtain a non-volatile residue and fracctionated on a Silica Gel 60 column. The antioxidant activity was determined by measuring peroxide value obtained after heating olive oil at 70 °C for 48 h. Six compounds were isolated and purified, four of these had antioxidant activity, α-tocopherol and three methoxylated flavones were identified using spectroscopic methods. This study confirmed that non-volatile fractions of essential orange oil contain natural antioxidants diferent from α-tocopherol.

    Existe un creciente interés en la industria alimentaria y en la medicina preventiva por la búsqueda de «antioxidantes naturales», por lo que nos planteamos evaluar la actividad antioxidante del residuo no volátil del aceite esencial de naranja contra la oxidación del aceite de oliva sin retinar y de reciente extracción. Mediante destilación del aceite esencial de naranja se obtuvo el residuo no-volátil, el cual se fraccionó en columna de silica gel 60. La actividad antioxidante fue medida por el valor de peróxidos producidos por el aceite de oliva al provocar la oxidación por calentamiento a 70 °C durante 48 h. Se aislaron seis compuestos mediante HPLC preparativo de los cuales cuatro tuvieron actividad antioxidante. Usando métodos espectroscópicos se identificaron α-tocoferol y tres flavonas metoxiladas. Con este estudio se confirmó que la fracción no volátil del aceite esencial de naranja contiene antioxidantes naturales diferentes al α-tocoferol.

    Diffusion brazing of Al-6061 alloy containing 15 vol. pct Al2O3 particles was attempted using Cu-Sn interlayer. Joint formation was attributed to the solid-state interdiffusion of Cu and Sn followed by eutectic formation and subsequent isothermal solidification. Examination of the joint region using scanning electron microprobe analyzer (EPMA), wavelength dispersive spectroscopy (WDS) and X-ray diffraction (XRD) showed the formation of intermetallic phases such as Al7Cu3Mg3, Mg2Cu6Al5, Cu3Sn, and Mg2Sn. The results indicated an increase in joint strength with increasing bonding time giving the highest joint shear strength of 94 MPa at a bonding duration of 3 hours.

    The enhancement of the stratospheric aerosol layer by volcanic eruptions induces a complex set of responses causing global and regional climate effects on a broad range of timescales. Uncertainties exist regarding the climatic response to strong volcanic forcing identified in coupled climate simulations that contributed to the fifth phase of the Coupled Model Intercomparison Project (CMIP5). In order to better understand the sources of these model diversities, the Model Intercomparison Project on the climatic response to Volcanic forcing (VolMIP) has defined a coordinated set of idealized volcanic perturbation experiments to be carried out in alignment with the CMIP6 protocol. VolMIP provides a common stratospheric aerosol data set for each experiment to minimize differences in the applied volcanic forcing. It defines a set of initial conditions to assess how internal climate variability contributes to determining the response. VolMIP will assess to what extent volcanically forced responses of the coupled ocean-atmosphere system are robustly simulated by state-of-the-art coupled climate models and identify the causes that limit robust simulated behavior, especially differences in the treatment of physical processes. This paper illustrates the design of the idealized volcanic perturbation experiments in the VolMIP protocol and describes the common aerosol forcing input data sets to be used.

La ingesta del aceite produjo caída en los valores promedio del CT, y AGNE con elevación del c-HDL en ambos grupos. La dosis de 10 mL se asoció a mayores niveles de insulina en el grupo aleatorizado a recibir 10 ml. El aceite de sacha inchi parece tener efectos benéficos sobre el perfil lipídico en pacientes con dislipidemia, requiriéndose la evaluación de su eficacia y seguridad en ensayos clínicos aleatorizados.We performed a pilot, experimental, open study in order to know the effect, effective dosage and secondary effects of sacha inchi´s (Plukenetia volúbilis L oil on the lipid profiles of patients with hypercholesterolemia. We included 24 patients of ages 35 to 75, to whom we measured total cholesterol (TC, HDL, triglycerides (Tg, glucose (G, non-esterified fatty acids (NEFA and insulin (I levels in blood, then we randomized them to receive sacha inchi oil orally 5 ml or 10 ml of a suspension of sacha inchi oil (2gr/5ml for four months. The oil intake produced a decrease in the mean values of TC, and NEFA, and a rise in HDL in both subgroups. The subgroup receiving 10 ml was associated to an increase in the insulin levels. Sacha inchi oil appears to have beneficial effects on the lipid profile of patients with dyslipidemia, but their efficacy and security should be evaluated in randomized clinical trials.

    Full Text Available The corrosion of copper in the presence of volatile organic acids is frequent. Thus, for example, it is known that failures by corrosion of the copper tubes take place in the air conditioning equipment, caused by volatile organic acids emitted by oils used in their manufacturing. Another frequent case is the corrosion of copper objects caused by the acids emitted by the materials used in packing, wood and resins, amongst others. This communication presents the corrosion results of copper exposed to 100% relative humidity and different concentrations (10-300 ppm of formic [HCOOH], acetic [CH3COOH], propionic [CH3CH2COOH] and butyric [CH3(CH22COOH] acid vapours, for short exposure times. The techniques used were gravimetric analysis, scanning electron microscopy (SEM and X-ray diffraction (XRD.

    Full Text Available Ceramic cutting inserts coated with ten-fold alternating micro- and nanocrystalline diamond (MCD/NCD layers grown by hot filament chemical vapor deposition (CVD were tested in the machining of an Al based metallic matrix composite (MMC containing 15 vol % Al2O3 particles. Inserts with total coating thicknesses of approximately 12 µm and 24 µm were produced and used in turning: cutting speed (v of 250 to 1000 m·min−1; depth of cut (DOC from 0.5 to 3 mm and feed (f between 0.1 and 0.4 mm·rev−1. The main cutting force increases linearly with DOC (ca. 294 N per mm and with feed (ca. 640 N per mm·rev−1. The thicker coatings work within the following limits: DOC up to 1.5 mm and maximum speeds of 750 m·min−1 for feeds up to 0.4 mm·rev−1. Flank wear is predominant but crater wear is also observed due to the negative tool normal rake. Layer-by-layer wear of the tool rake, and not total delamination from the substrate, evidenced one of the advantages of using a multilayer design. The MCD/NCD multilayer diamond coated indexable inserts have longer tool life than most CVD diamond systems and behave as well as most polycrystalline diamond (PCD tools.

    In this paper, differences between the 24-h average PM{sub 10} concentrations of Wedding {sup {beta}}-gauge monitor and Andersen or Wedding hi-vol sampler were studied. When the deliquescent point is not exceeded, PM{sub 10} concentrations of the {sup {beta}}-gauge are close to those of the manual samplers. The ratio of {sup {beta}}-gauge PM{sub 10} to Andersen PM{sub 10} and Wedding PM{sub 10} is 1.08{+-}0.06 and 1.09{+-}0.12, respectively. However, when the deliquescent point is exceeded, water absorption by the inorganics of aerosols leads to higher PM{sub 10} concentrations of the {sup {beta}}-gauge compared to those of the manual sampler. The ratio of {sup {beta}}-gauge PM{sub 10} to Andersen PM{sub 10} and Wedding PM{sub 10} is 1.21{+-}0.22 and 1.27{+-}0.15, respectively. However, due to evaporation of water from the aerosols collected on the filter tape of the {sup {beta}}-gauge, differences in PM{sub 10} concentrations are much less than theoretically calculated.

    Full Text Available Aldose Reductase (AR is the polyol pathway key enzyme which converts glucose to sorbitol. High glucose availability in insulin resistant tissues in diabetes leads into an accumulation of sorbitol, which has been associated with typical chronic complications of this disease, such as neuropathy, nephropathy and retinopathy. In this study, 71 flavonoids AR inhibitors were subjected to two methods of SAR to verify crucial substituents. The first method used the PCA (Principal Component Analysis to elucidate physical and chemical characteristics in the molecules that would be essential for the activity, employing VolSurf descriptors. The rate obtained explained 53% of the system total variance and revealed that a hydrophobic-hydrophilic balance in the molecules is required, since very polar or nonpolar substituents decrease the activity. Artificial Neural Networks (ANNs was also employed to determine key substituents by evaluating substitution patterns, using NMR data. This study had a high success rate (85% accuracy in the training set and 88% accuracy in the test set and showed polihydroxilations are essential for high activity and methoxylations and glicosilations primarily at positions C7, C3' and C4' decrease the activity.

    The CONNECT-OptiVol study is designed to investigate whether wireless fluid monitoring using OptiVol alerts as well as implantable cardioverter-defibrillator (ICD) remote monitoring (RM) reduces cardiac decompensations and health care utilization in ICD patients, as compared to standard clinical care. Patients undergoing implantation of wireless telemetry-enabled dual chamber (ICD-DR) or cardiac resynchronization therapy/defibrillator (CRT-D) devices with the OptiVol feature are eligible for the study. In a randomized fashion, OptiVol function, its audible alert as well as its remote alert, and other ICD RM alerts are switched ON or OFF. The primary study objective is to estimate an improvement of heart failure status. The primary endpoint is measured as a prolongation of the time to first hospitalization due to worsened heart failure. The secondary objectives are to estimate: a reduction of the time from event to clinical decision, a reduction of the rate of health care utilization, and improved quality of life (QoL) measures (secondary endpoints). The study is designed as a single center pilot study with 180 patients randomized 1:1 to the two study arms. The CONNECT-OptiVol study aims to answer whether wireless fluid monitoring integrated into RM may reduce cardiac decompensations and health care utilization in ICD patients. The results can be used to adequately power future studies evaluating the benefit of these features. Study enrollment has been completed, and follow-up is expected to be finished in September 2012.

  20. The Gunite and Associated Tanks Remediation Project Tank Waste Retrieval Performance and Lessons Learned, vol. 2 [of 2

    Energy Technology Data Exchange (ETDEWEB)

    Lewis, BE

    2003-10-07

    The Gunite and Associated Tanks (GAAT) Remediation Project was the first of its kind performed in the United States. Robotics and remotely operated equipment were used to successfully transfer almost 94,000 gal of remote-handled transuranic sludge containing over 81,000 Ci of radioactive contamination from nine large underground storage tanks at the Oak Ridge National Laboratory (ORNL). The sludge was transferred with over 439,000 gal of radioactive waste supernatant and {approx}420,500 gal of fresh water that was used in sluicing operations. The GAATs are located in a high-traffic area of ORNL near a main thoroughfare. Volume 1 provides information on the various phases of the project and describes the types of equipment used. Volume 1 also discusses the tank waste retrieval performance and the lessons learned during the remediation effort. Volume 2 consists of the following appendixes, which are referenced in Vol. 1: A--Background Information for the Gunite and Associated Tanks Operable Unit; B--Annotated Bibliography; C--GAAT Equipment Matrix; D--Comprehensive Listing of the Sample Analysis Data from the GAAT Remediation Project; and E--Vendor List for the GAAT Remediation Project. The remediation of the GAATs was completed {approx}5.5 years ahead of schedule and {approx}$120,435K below the cost estimated in the Remedial Investigation/Feasibility Study for the project. These schedule and cost savings were a direct result of the selection and use of state-of-the-art technologies and the dedication and drive of the engineers, technicians, managers, craft workers, and support personnel that made up the GAAT Remediation Project Team.

    20 vol.% cubic boron nitride (cBN) dispersoid reinforced NiCrAl matrix nanocomposite coating was prepared by cold spray using mechanically alloyed nanostructured composite powders. The as-sprayed nanocomposite coating was annealed at a temperature of 750 °C to enhance the inter-particle bonding. Microstructure of spray powders and coatings was characterized. Vickers microhardness of the coatings was measured. Two-body abrasive wear behavior of the coatings was examined on a pin-on-disk test. It was found that, in mechanically alloyed composite powders, nano-sized and submicro-sized cBN particles are uniformly distributed in nanocrystalline NiCrAl matrix. Dense coating was deposited by cold spray at a gas temperature of 650 °C with the same phases and grain size as those of the starting powder. Vickers hardness test yielded a hardness of 1063 HV for the as-sprayed 20 vol.% cBN-NiCrAl coating. After annealed at 750 °C for 5 h, unbonded inter-particle boundaries were partially healed and evident grain growth of nanocrystalline NiCrAl was avoided. Wear resistance of the as-sprayed 20 vol.% cBN-NiCrAl nanocomposite coating was comparable to the HVOF-sprayed WC-12Co coating. Annealing of the nanocomposite coating resulted in the improvement of wear resistance by a factor of ~33% owing to the enhanced inter-particle bonding. Main material removal mechanisms during the abrasive wear are also discussed.

Volatiles were isolated from the headspace of fresh fruit by SPME and identified by GC-MS. Pickled peppers were produced for sensory evaluation. Aroma descriptors were evaluated by Check-All-That-Apply (CATA method, and the frequency data were submitted to Correspondence Analysis. Flavor acceptance was assessed by hedonic scale and analyzed by ANOVA. BRS Seriema showed the richest volatile profile, with 55 identified compounds, and up to 40% were compounds with sweet aroma notes. CNPH 4080 showed similar volatile profile to that of Biquinho pepper, but it had higher amounts of pepper-like and green-note compounds. The samples did not differ in terms of flavor acceptance, but they showed differences in aroma quality confirming the differences found in the volatile profiles. The C. chinense varieties developed by Embrapa proved to be more aromatic than Biquinho variety, and were well accepted by the judges.O objetivo deste estudo foi comparar a qualidade sensorial e o perfil de compostos voláteis de novas variedades de pimenta Capsicum (CNPH 4080, uma linhagem de cumari-do-pará, e BRS Seriema, com uma variedade comercial (Biquinho.

Car-3-ene was the major component of the cultivars Haden and Keitt, while the Tommy Atkins mango exhibited predominance of two constituents, car-3-ene and alpha-pinene. Other identified compounds were alpha-fenchene, alpha-camphene, p-cimene, beta-mircene, beta-phellandrene, limonene, alpha-terpinolene, beta-caryophyllene e alpha-humulene. Samples of the same cultivar demonstrated great homogeneity, with no statistically significant difference being observed among the three lots analyzed for each cultivar.

    MT measurement of transects was made in the central part of North-Eastern Japan Arc to clarify tectonics of subduction zones. 1-D, 2-D and 3-D resistivity structures are observed in surface layers, and zones shallower and deeper than a Conrad surface, respectively. A main structure direction is S-N or NNE-SSW. Ishinomaki-Chokai tectonic line and low- resistivity zones due to Quaternary volcanos (Naruko, Onikobe) exist in a backbone range region. Resistivity is 100{Omega}{center_dot}m or less by Bostick Inversion except Mesozoic and Palaeozoic layers in the southern Kitakami mountainous region, resulting in a good agreement with previous results in a north transect. Resistivity is several {Omega}{center_dot}m and depth is several km around Shinjo basin and in surface layers of Kitakami River region. The backbone range region shows complex resistivity structures because of volcanic activity and wide-area hot water activity. High-resistivity layers correspond to stable Mesozoic and Palaeozoic land layers. Seismic velocity increases in the low-resistivity zone. Earthquake generally occurs at the boundary between resistivity structures. 68 refs., 9 figs., 2 tabs.

    To survey the structure at the depth between 20 and 30 m, field tests were conducted by means of vertical electric and VFL-MT (magnetotelluric) survey. Tegatayama tunnel has a total length of 276 m, width of 7.5 m, and height of 4.7 m, and the depth from the surface is about 28 m near the top of mountain. Near the tunnel, the thickness of surface soil is about 60 cm, which consists of clay soil including soft mudstone gravel. It was found that terrace deposit is distributed up to the depth of 8 m, and that mudstone is distributed below the depth of 8 m. Weighted four-electrode method was adopted for the vertical electrical survey. Measurements were conducted at the immediately above the tunnel, 10 m apart from the center of tunnel in the right and left, and 20 m apart from the center in the east. For the VLF-MT method, component of frequency 22.2 kHz was used. As a result of the tests, it was difficult to illustrate the existence of tunnel from the vertical electrical survey only at one point. Feature of the tunnel could be well illustrated by means of the VLF-MT method. 3 refs., 9 figs.

    Fluid flow tomography (FFT) was applied to monitor the behavior of underground fluid in steam enhanced oil recovery (EOR) for oil sand reservoirs. FFT uses electrode arrangement of a mise-a-la-masse method, and continuously measures time variation in charged and spontaneous potential at various surface points to obtain realtime the images of underground seepage flow. It continuously measures ground surface potentials of 120 channels at intervals of 2s by applying alternative DC between a casing pipe and distant current electrode. It separates charged and spontaneous potential components, and converts them into time series data. It estimates the time and spacial distributions of seepage flow from time variation in spontaneous potential. It determines the change rate distribution of time-sliced apparent resistivity from charged potential to estimate the scale and area of seepage flow. As the experimental result, positive and negative electrodes in the change rate distribution were observed, and the direction connecting each electrode agreed with that of resistivity anomaly. FFT could observe realtime time variation in apparent resistivity due to steam injection. 9 refs., 7 figs.

    Fluid flow tomography (FFT) was developed to monitor enhanced oil recovery IOR/EOR operations. This method uses a casing pipe as linear current source by connecting a current electrode with a well inlet, and the other electrode is grounded at a point far different from the well. Potentials are rapidly measured at the same time by multi-channel receiving electrodes installed on the ground to obtain time series data composed of charged potential and superimposed spontaneous potential. After separation of both potentials, the charged potential data are processed by the conventional mise-a-la-masse method to extract local anomaly, determine the residual distribution and relative change distribution of time-sliced apparent resistivity, and obtain the 3-D profile of fluid. The spontaneous potential is also processed to obtain the deflection distribution of time-sliced potential at a specific time. Quantitative 3-D interpretation is conducted focusing attention on the generation mechanism of spontaneous potential. Behavior of underground permeated flow is determined as time series animation images to image fluid direction. This method was effective in real fields. 8 refs., 4 figs.

    This paper proposes a cone type electro-hydrodynamical (EHD) heat collector, describes its structure and principle, and mentions possibility of improving the heat collecting efficiency. The paper proposes a heat collector with a shape close to a cone. Trees are of cone form so that their every leaf, branch and truck can capture solar energy efficiently. Imitating this fact existing in the natural world, a cone-shaped heat collector was fabricated on a trial basis to discuss its heat collecting efficiency. Furthermore, black round stones are placed in the inner cone of the cone- shaped heat collector of double-glass structure. A low boiling point medium is placed between the inner and outer cones to cause corona discharge in vapor generated by absorbing the solar heat, and generate corona wind for an attempt to accelerate heat transfer into a heat exchanger. Thus, development was made on a cone-shaped high-efficiency heat collector utilizing electro-hydrodynamical (EHD) effect, and elucidation was given on dynamic phenomena of an electro-thermal fluid. Heat transfer in the EHD heat collector has a possibility of being accelerated by generation of ionic wind. In addition, it is thought that there would be an optimum value in applied voltage to increase electric charge supply as a result of corona discharge. 1 ref., 2 figs.

    The electric system of a solar vehicle was removed and the fundamental characteristics examined in order to carry out a basic experiment on the electric system. Using a basic circuit with panels, batteries and loads connected, the voltage and current were measured in the presence/absence of the trackers, batteries, etc., and then, their effects were examined. Simultaneously, the quantity of solar radiation was also measured. The lowering of the output voltage was somewhat relaxed with the use of the trackers. Further, with the trackers used, the output voltage of the panel was small in spite of a large quantity of solar radiation compared to the case without the trackers, which was due to the restriction of the output voltage by the trackers. When measured without batteries, the output voltage of the panel was such that the load current was also influenced by the variation of insolation, so that, with a large decrease in insolation, the load current was decreased with the supply of current suspended from the panel. 7 figs., 1 tab.

    The effects of casting conditions and deformation processing on the mechanical properties of unreinforced A356 aluminum and A356-20 vol pct SiC composite were investigated by tensile properties in these compounds fabricated by either sand casting or squeeze casting techniques followed by hot working to 33, 50, 90, and 95 percent reductions. The evolution of the microstructure and values of tensile properties were evaluated for the cast materials in each of the hot worked conditions. It was found that, while the deformation processing of the sand-cast composite resulted in banding of the Al and SiC particles within the microstructure, such features were not observed in the squeeze-cast microstructure. The tensile strengths of the squeeze cast materials was found to be higher than those of the sand cast materials, for both the unreinforced and composite samples, while increased amounts of deformation were found to improve the ductility of the composite.

    Full Text Available The corrosion behavior of 6061/Al-15 vol. pct. SiC(p composite and 6061 Al base alloy was investigated in a sodium hydroxide solution. The electrochemical parameters were derived from potentiodynamic polarization and electrochemical impedance spectroscopic (EIS techniques. The results showed that the corrosion resistance of the composite was lower than that of the base alloy in selected corrosion media. The corrosion rates of both the composite and the base alloy increased with the increase in the concentration of sodium hydroxide and also with the increase in temperature. The surface morphology of the metal surface was investigated using scanning electron microscope (SEM. Activation energy was evaluated using Arrhenius equation, and enthalpy of activation and entropy of activation values were calculated using transition state equation.

    Full Text Available La fibrosis pulmonar idiopática (FPI es una enfermedad que se caracteriza por presentar un compromiso pulmonar de tipo restrictivo, resultante de una reducción en la complacencia pulmonar secundaria a fibrosis difusa. En el enfisema, la pérdida de elasticidad pulmonar y el colapso de las vías aéreas periféricas generan obstrucción e hiperinflación. El efecto simultáneo que ambas enfermedades producen sobre la fisiología pulmonar no es del todo claro y se han descripto volúmenes pulmonares normales o casi normales. Presentamos 4 pacientes de sexo masculino de 64, 60, 73 y 70 años, con antecedentes de tabaquismo e historia de disnea progresiva, tres de ellos con grave limitación en su calidad de vida al momento de la consulta. En la tomografía de tórax de alta resolución todos los pacientes presentaban signos de enfermedad intersticial pulmonar avanzada, con cambios de tipo fibrótico con predominio basal y subpleural, que coexistían con enfisema centroacinar con predominio en lóbulos superiores. Uno de ellos tuvo confirmación diagnóstica de ambas condicioes por biopsia pulmonar a cielo abierto. En los cuatro pacientes la espirometría y volúmenes pulmonares fueron normales, pero tenían importante compromiso del intercambio gaseoso evaluado mediante el test de caminata de 6 minutos. Tres de los pacientes tenían hipertensión pulmonar grave diagnosticado por ecocardiograma. La presencia de volúmenes pulmonares normales no excluye un diagnóstico de fibrosis pulmonar idiopática en pacientes fumadores si coexisten evidencias tomográficas de enfisema. En estos pacientes el grado de compromiso funcional, determinado por la reducción de los volúmenes pulmonares, no debería ser considerado en la evaluación de la gravedad.Pulmonary function tests in idiopathic pulmonary fibrosis characteristically show a restrictive pattern, resulting from reduction of pulmonary compliance due to diffuse fibrosis.

    Full Text Available The objective of this work was to identify and verify the influence of time and temperature on the volatile compounds profile of fresh cut peki. Peki fruits were washed, sanitized, their kernels were extracted, and they were packaged and stored for 15 days at 0, 5, and 10 °C and 6 days at 22 °C. The volatiles compounds were analyzed by GC - MS. Ethyl hexanoate and ethyl octanoate were found in higher percentages, 63 and 16.3%, respectively. The determined volatiles were not influenced by the storage period. Hexanoic acid, ethyl 2-octenoate and ethyl decanoate were not influenced by the different temperatures. The temperatures 0, 5, and 10 °C did not influence ethyl hexanoate, ethyl 2-hexenoate and ethyl octanoate either. In addition, the temperatures 5, 10, and 22 °C did not influence ethyl hexanoate, cis-β-ocimene and ethyl octanoate. The temperature of 22 °C determined higher percentages of ethyl hexanoate and lower percentages of ethyl octanoate, in comparison to the temperature of 0 °C, and higher percentages of ethyl 2-hexenoate in comparison to the temperatures of 0, 5, and 10 °C. The temperature of 5 °C determined higher percentage of cis-β-ocimene when compared with the temperature of 0 °C. The storage temperatures of 0 and 5 °C were the most appropriate for the conservation.O objetivo do trabalho foi identificar e verificar a influência do tempo e da temperatura sobre o perfil dos compostos voláteis de pequi minimamente processado.

    Full Text Available The creep behavior of a powder metallurgy (PM Al6061-15 vol % SiCw metal matrix composite has been studied. This behavior has been compared to that of 6061Al cast alloy and 6061Al PM alloy. The creep response of the PM unreinforced alloy is better than that of the cast 6061Al alloy. Similarly, the behavior of the composite is better than that of the PM unreinforced alloy. Two microstructural factors have been considered the responsible ones of this improvement. The first one is the dispersion of Al2O3 oxide particles of nanometric scale. The second one, is the presence of the SiC whisker reinforcement of micrometric scale. Despite the similar strengthening effect, the intrinsic nature of the reinforcing mechanism is, however, different for each type of particle due to the different microstructural scale.Se ha realizado un estudio de las propiedades en fluencia del material compuesto pulvimetalúrgico Al6061-15 vol % SiCw. Su comportamiento se ha comparado con el de la aleación Al6061 pulvimetalúrgica y la aleación Al6061 de colada. El comportamiento del material pulvimetalúrgico sin reforzar mejora respecto al del material de colada. Al mismo tiempo, el del material compuesto mejora respecto al comportamiento del material pulvimetalúrgico sin reforzar. Se consideran dos factores microestructurales como los principales responsables de la mejora de las propiedades en fluencia de este material compuesto. Por un lado, las partículas de Al2O3 de tamaño nanométrico y, por otro, las partículas de fibra corta cerámicas de SiC de tamaño micrométrico. Aunque ambos tipos de partículas dan lugar a un efecto de refuerzo similar, los mecanismos intrínsecos asociados a la presencia de estas partículas tienen una naturaleza diferente debido a la diferencia en la escala microestructural.

    Full Text Available Neste trabalho foi estudada a variação da composição dos voláteis de dois cafés "gourmet" e de um café mole em função do grau de torrefação. Os cafés provenientes de Araguari, cerrado do Triângulo Mineiro, foram submetidos à torra americana (grãos marrons claros, média (grãos marrons e forte (grãos pretos e, em seguida, moídos e submetidos a uma destilação por arraste de vapor em contra-corrente com diclorometano. A análise de cromatografia gasosa acoplada à espectrometria de massas (CG-EM dos constituintes voláteis mostrou que piridina, pirazina e derivados, furfural e derivados são os principais constituintes voláteis dos cafés analisados. Mostrou ainda que não é possível diferenciar os três tipos de café pelos compostos dominantes (concentração acima de 1% no aroma. Foi observado também que a torra afeta sensivelmente os resultados, sendo que a torra americana, usada normalmente na prova da xícara para classificação sensorial de cafés, produz alguns voláteis de forte impacto no aroma que não aparecem na torra média nem na forte, além de apresentar concentrações dos componentes mais comuns muito diferentes daquelas observadas nas outras duas torras.

    Full Text Available Além das brassicaceas associadas à solarização do solo, novos materiais vegetais como a mandioca e a mamona têm apresentado potencial no controle de fitopatógenos de solo. Assim, objetivou-se verificar os efeitos da incorporação e decomposição de parte aérea de brócolis, mamona e mandioca brava e mansa, associadas à solarização, em conjuntos de microcosmos, sob condições de ambiente controlado, na sobrevivência das estruturas de resistência de Fusarium oxysporum f. sp. lycopersici Raça 2, Macrophomina phaseolina, Rhizoctonia solani AG-4 HGI e Sclerotium rolfsii; e identificar e apontar o(s volátil(eis emanado(s pela decomposição dos materiais, que poderia(m estar correlacionado(s com a inativação dos fitopatógenos. Quanto à sobrevivência dos patógenos, quatro ensaios idênticos foram instalados nos microcosmos, com quatro períodos de exposição independentes (7, 14, 21 e 28 dias. A identificação dos voláteis contou com ensaios realizados sob as mesmas condições da sobrevivência, mas em frascos âmbar e com cromatografia gasosa com detectores por espectrometria de massas (GC-MS e por ionização em chama (GC-FID, utilizando a técnica de Microextração em Fase Sólida - SPME. Os tratamentos solo+materiais vegetais, ao longo dos períodos testados, reduziram a sobrevivência das estruturas de resistência de todos os fungos. No geral, destacaram-se o brócolis e a mandioca brava, além da mandioca mansa para S. rolfsii. Os voláteis identificados foram oriundos da decomposição de brócolis, mamona e mandioca mansa. Foram identificados 26, 37 e 29 compostos voláteis para brócolis, mamona e mandioca mansa, respectivamente. Correlações positivas e negativas foram observadas entre alguns voláteis e a média dos compostos com a sobrevivência das estruturas de resistência dos fitopatogênicos.

  19. A new and fast methodology to assess oxidative damage in cardiovascular diseases risk development through eVol-MEPS-UHPLC analysis of four urinary biomarkers.

    In this work, a new, fast and reliable methodology using a digitally controlled microextraction by packed sorbent (eVol(®)-MEPS) followed by ultra-high pressure liquid chromatography (UHPLC) analysis with photodiodes (PDA) detection, was developed to establish the urinary profile levels of four putative oxidative stress biomarkers (OSBs) in healthy subjects and patients evidencing cardiovascular diseases (CVDs). This data was used to verify the suitability of the selected OSBs (uric acid-UAc, malondialdehyde-MDA, 5-(hydroxymethyl)uracil-5-HMUra and 8-hydroxy-2'-deoxyguanosine-8-oxodG) as potential biomarkers of CVDs progression. Important parameters affecting the efficiency of the extraction process were optimized, particularly stationary phase selection, pH influence, sample volume, number of extraction cycles and washing and elution volumes. The experimental conditions that allowed the best extraction efficiency, expressed in terms of total area of the target analytes and data reproducibility, includes a 10 times dilution and pH adjustment of the urine samples to 6.0, followed by a gradient elution through the C8 adsorbent with 5 times 50 µL of 0.01% formic acid and 3×50 µL of 20% methanol in 0.01% formic acid. The chromatographic separation of the target analytes was performed with a HSS T3 column (100 mm × 2.1 mm, 1.7 µm in particle size) using 0.01% formic acid 20% methanol at 250 µL min(-1). The methodology was validated in terms of selectivity, linearity, instrumental limit of detection (LOD), method limit of quantification (LOQ), matrix effect, accuracy and precision (intra-and inter-day). Good results were obtained in terms of selectivity and linearity (r(2)>0.9906), as well as the LOD and LOQ, whose values were low, ranging from 0.00005 to 0.72 µg mL(-1) and 0.00023 to 2.31 µg mL(-1), respectively. The recovery results (91.1-123.0%), intra-day (1.0-8.3%), inter-day precision (4.6-6.3%) and the matrix effect (60.1-110.3%) of eVol

    The compression properties and electrical conductivity of in-situ 20 vol.% nano-sized TiCx/Cu composites fabricated via combustion synthesis and hot press in Cu-Ti-CNTs system at various particles size and morphology were investigated. Cubic-TiCx/Cu composite had higher ultimate compression strength (σUCS), yield strength (σ0.2), and electric conductivity, compared with those of spherical-TiCx/Cu composite. The σUCS, σ0.2, and electrical conductivity of cubic-TiCx/Cu composite increased by 4.37%, 20.7%, and 17.8% compared with those of spherical-TiCx/Cu composite (526 MPa, 183 MPa, and 55.6% International Annealed Copper Standard, IACS). Spherical-TiCx/Cu composite with average particle size of ~94 nm exhibited higher ultimate compression strength, yield strength, and electrical conductivity compared with those of spherical-TiCx/Cu composite with 46 nm in size. The σUCS, σ0.2, and electrical conductivity of spherical-TiCx/Cu composite with average size of ~94 nm in size increased by 17.8%, 33.9%, and 62.5% compared with those of spherical-TiCx/Cu composite (417 MPa, 121 MPa, and 40.3% IACS) with particle size of 49 nm, respectively. Cubic-shaped TiCx particles with sharp corners and edges led to stress/strain localization, which enhanced the compression strength of the composites. The agglomeration of spherical-TiCx particles with small size led to the compression strength reduction of the composites.

  1. Effects of CO2 pneumoperitoneum on blood flow vol-ume of abdominal organs of rabbits with controlled hem-orrhagic shock and liver impact injuries

    Institute of Scientific and Technical Information of China (English)

    Objective: To investigate the effects of CO2 pneumo-peritoneum on blood flow volume of abdominal organs of rabbits with controlled hemorrhagic shock model and liver impact injuries.Methods: After controlled hemorrhagic shock and liver impact injuries, the rabbit model was established. Eighteen rabbits subjected to hemorrhagic shock and liver impact inju-ries were divided into 3 groups randomly according to the volume of lost blood: light hemorrhagic shock (blood loss volume was 10%, 6 ml/kg), moderate hemorrhagic shock (20%, 12 ml/kg) and severe hemorrhagic shock (40%, 22 ml/kg). Intraabdominal pressures of CO2 pneumoperitoneum was 10 mmHg. Color-labeled microspheres were used to mea-sure the blood flow volume of the liver, kidney and stomach before pneumoperitoneum at 30 minutes and 2 hours after pneumoperitoneum and 30 minutes after deflation. And the mortality and hepatic traumatic condition of rabbits were recorded.Results: Of the 18 rabbits, there were 9 with liver impact injuries at Grade Ⅰ, 8 at Grade Ⅱ and Ⅰ at Grade Ⅲ (according to AIS-2005). The mortality rate in light hemorrhagic shock group was 33.33%, and that in moderate or severe hemor-rhagic shock group was 100% within 30 minutes and 2 hours after pneumoperitoneum, respectively. The blood flow vol-ume in the organs detected decreased at 30 minutes under pneumoperitoneum in light and moderate hemorrhagic shock groups. At the same time, the blood flow volume of the liver in moderate hemorrhagic shock group decreased more sig-nificantly than that in light hemorrhagic shock group.Conclusions: The blood flow volume of abdominal organs in rabbits is decreased obviously under CO2 pneumoperitoneum, with fairly high mortality rate. It is be-lieved that CO2 pneumoperitoneum should cautiously be used in abdominal injury accompanied with hemorrhagic shock, especially under non-resuscitation conditions.

    Energy Technology Data Exchange (ETDEWEB)

    2004-07-12

    IBIS (massively parallelized version 2) is a comprehensive model of terrestrial biospheric processes, and includes land surface physics, canopy physiology, plant phenology, vegetation dynamics and competition, and carbon cycling. The land surface module simulates the energy, water, carbon and momentum balance of soil/vegetation/atmospheric system on a short time step consistent with general circulation models (20-60 minutes). The module includes two vegetation layers (trees, and grasses and shrubs) and six soil layers to simulate soil temperature, soil water, and soil ice content over a total depth of 4 m. Physiologically-based formulations of C3 and C4 photosynthesis (Farquhar. et al., 1980), stomatal conductance (Collatz, et al., 1992; Collatz, et al., 1991) and respiration (Amthor, 1984) are used to simulate canopy gas exchange processes. Budburst and senescence depend on climatic factors following the empirical algorithm presented by Botta, et al. (2000). The annual carbon balance allows the vegetation dynamics submodel to predict the maximum leaf area index and biomass for 12 plant functional types, which compete for light and water. IBIS represents vegetation dynamics using very simple competition rules. The relative abundance of the 12 platn functional types in each grid cell changes in time according to their ability to photosynthesize and use water, IBIS simulates carbon cycling through vegetation, litter and soil organic matter. The soil biogeochemistry model of Verbene, et al. (1990). The total below-ground carbon in the first meter of soil is divided into pools characterized by their residence time: from a few hours for the microbal biomass to more than 1000 years for stabilized organic matter. Decomposition rates of litter and soil carbon depend on soil temperature and soil moisture.

    Full Text Available Changes in the profile of volatile compounds after the heating of refined soybean oil without adding antioxidants, and treated with quercetin and chlorogenic acid (5-CQA were investigated by GC/FID, GC/MS, and GC/SNIFFING. The heating temperature of the oil sample was 20 °C for the first minute, and then it was increased up to 160 °C at the rate of 10 °C min-1. The final temperature was kept for 10 minutes. 19 volatiles were identified in the heated samples without antioxidants. Medium-chain carbonyls predominated in the volatile fraction, mainly 2-heptenal, 2,4-heptadienal and 2,4-decadienal. Around 11 to 15 volatile compounds were detected in the heated samples treated with 5-CQA and quercetin, respectively. 5-CQA was not very efficient in delaying the formation of oxidative volatile compounds. The samples quercetin presented lower proportion of carbonyls with C6-C9.. The GC peak area data were used as an approach to estimate the relative content of each volatile compound and indicate that the samples treated with quercetin (p As alterações no perfil de compostos voláteis, após o aquecimento de óleo de soja refinado sem a adição de antioxidantes e tratado previamente com quercetina e ácido clorogênico (5-ACQ, foram investigadas através da CG/DIC, CG/EM e CG/SNIFFING.

    To investigate the change of global and regional cerebral blood flow after heart transplantation (HT) in congestive heart failure (CHF) patients. Twenty-one patients with CHF who underwent HT (45{+-}12 yrs, M/F=19/2) and 10 healthy volunteers (39{+-}13 yrs, M/F = 7/3) were prospectively included. All patients underwent echocardiography and radionuclide angiography including brain and aorta with brain SPECT which was performed after iv bolus injection of Tc-99m ECD (740MBq) before (175{+-}253 days) and after (129{+-}82 days) HT. Patients were divided into two groups according to the interval between HT and postoperative SPECT [early follow-up (f/u): <6 mo, n=14; late f/u: >6 mo, n=7]. Global CBF (gCBF) of bilateral hemispheres were calculated by Patlak graphical analysis. Absolute rCBF map was obtained from brain SPECT by Lassen's correction algorithm. Age-corrected voxel-based analysis using SPM2 and automatic VOl analysis were performed to assess the rCBF change. Cardiac ejection fraction of all patients improved after HT (20.8%{yields}64.0%). gCBF was reduced compared to normal before HT (35.7{+-}3.9 vs. 49.1{+-}3.0 ml/100g/min; p<0.001) and improved postoperatively (46.6{+-}5.4, p<0.001). The preoperative gCBFs of early and late f/u group were not different (34.6{+-}3.2 vs. 38.0{+-}4.4, p=0.149) but postoperative gCBF (43.9{+-}3.7) of late f/u group was higher than those (52.0{+-}4.0) of early f/u group (p<0.001). On voxel-based analysis, preoperative rCBF was reduced in entire brain but most severely in bilateral superior and inferior frontal cortex, supplementary motor area, precuneus and anterior cingulum, compared to normals (uncorrected p<0.001). After HT, rCBF of these areas improved more significantly in late f/u group than in early f/u group but still lower than normals. Global CBF was significantly reduced in CHF patients and improved after HT. rCBFs of the frontal cortex, precuneus and cingulum were most severely reduced and slowly improved after

    Full Text Available RESUMO Aleloquímicos são substâncias liberadas por certas espécies vegetais no ambiente que influenciam a germinação e o desenvolvimento de outras plantas. O objetivo desse estudo foi avaliar o potencial fitotóxico de Cleome guianensis Aubl., bem como determinar o grau de estresse oxidativo causado em Senna occidentalis L. Para isso, o óleo das folhas de C. guianensis, nas concentrações 0,5 µg/mL, 1,0 µg/mL, 2,5 µg/mL e 5,0 µg/mL, em solução de 5 ml foi testado em bioensaios de germinação e de crescimento da raiz primária e do hipocótilo de S. occidentalis. Os indivíduos de S. occidentalis foram macerados, homogeneizados e submetidos a ensaios de quantificação da catalase, peroxidase, SOD e de peroxidação lipídica. Os resultados indicam que todas as concentrações do óleo volátil causaram um efeito negativo sobre a germinação e crescimento de S. occidentalis. Na concentração 5,0 µg/mL, houve 56% de inibição da germinação e 83% de inibição de crescimento do hipocótilo. Ainda, o óleo aumentou a atividade das enzimas induzidas pelo estresse oxidativo catalase, peroxidase e superóxido dismutase (SOD. Quanto à peroxidação lipídica, o óleo nas concentrações 1,0 µg/mL, 2,5 µg/mL e 5,0 µg/mL aumentou a produção de malondialdeído. Sendo assim, conclui-se que C. guianensis apresenta aleloquímicos que influenciam na germinação e no crescimento de S. occidentalis, além de aumentar a atividade das enzimas catalase, peroxidase, SOD e a produção de malondialdeído em S. occidentalis. Dessa forma, sugere-se a realização de estudos sobre o perfil químico do óleo a fim de descobrir as substâncias responsáveis por tais resultados e consolidar o potencial fitotóxico de C. guianensis.

    To grasp the three-dimensional structure of ancient tomb during the archaeological prospecting of Kaibukiyama ancient tomb, various electrical resistivity methods were tried. For the survey, firstly, in order to clarify the electrical resistivity structure of rear circular part of ancient tomb, roughly, mapping was conducted by means of two-electrode method using a multi-channel measuring system. Then, the vertical prospecting was conducted densely with a mesh form having VES intervals of 2 m as a detailed survey by means of Schlumberger method. For the three-dimensional inverse analysis of apparent electrical resistivity data by the two-electrode method, a program with high calculation speed was developed by using algorithm where Jacobian with a homogeneous model is adopted for the Jacobian calculation. As a result of the analysis, an outline of underground 3-D resistivity structure was determined. The resistivity anomaly with high values obtained from the results of 2-D inverse analysis of VES curve by means of Schlumberger method agreed well with the central part of the ancient tomb, which was confirmed during the archaeological survey. 4 refs., 8 figs.

    An efficient calculation method of potential distribution in the presence of an embedded body in multi-layer earth has been proposed by expanding the method of image with a consideration of multiple reflection between the ground surface and each underground boundary. For this method, when solving boundary integral equation with the potential of embedded body surface as only one unknown, i.e., when obtaining discretization equation, ordinary boundary element program developed for analyzing the finite closed region can be used. As an example, numerical calculation was conducted for the two-layer earth. The analysis expression of potential distribution in the case of the certain embedded body in two-layer earth has never published. Accordingly, the calculated results were compared with those by the integral equation method. As a result, it was concluded that the primary potential obtained from the present method agreed well with that obtained from the integral equation method. However, there was a disregarded difference in the secondary potential. For confirming the effectiveness, it was necessary to compare with another numerical calculation method, such as finite element method. 5 refs., 5 figs.

    We send the electric insulation to one of the technological problem to be solved in order to realize high reliability of the superconductive electric power equipment. This paper must also sufficiently consider not only dielectric characteristic and insulation characteristic but also material mechanical property in which they are excellent at very low temperature in the selection of insulating material. The representative insulating material of XLPE, LDPE mainly used in the region over room temperature the crack may arise by causing mechanical stress by cooling contracture of giant molecule, and the problem occurs as cryogenic insulating material in mechanical property. We propose the ethylene propylene rubber as cryogenic insulating material, and we carry out research and development of superconducting cable of the solid insulation system. We examined dielectric breakdown property and mechanical property of EPR at very low temperature this time. (NEDO)

    In order to design the cathodic protection of the equipments and piping facilities in the seawater quantitatively and more precisely, the research and development have been firstly advanced on the titanium made condenser and circulating water tubes as the object, and then the introduction of the numerical analysis to the corrosion phenomena has been tried. Through the steps such as the measurement of corrosion data for the input, the verification by the three dimensional model, the test by the actual equipments and facilities and so forth, a technology to get the potential distribution in the cathodic protection by the finite element method (FEM) has been developed. This analytical technology has the distinctive features as follows: Since this can make the compound model by combinating the different dimensions, the potential distribution analysis of the complicated structures with the various shapes and large scale can be done; In addition, if necessary, three dimensional potential distribution can be analyzed by using the three dimensional model. In this paper, accompanied with the plant orienting the compactification, a combination of the condenser with the ball cleaning facility and so forth, which have become to be required for the cathodic protection design with a higher accuracy, as well as the application example to the super stainless steel made seawater cooler and so forth are introduced. 2 refs., 16 figs., 3 tabs.

    By ZEV regulation of the California government in 1990, not only the United States but also European countries and Japan are largely interested in replacing gasoline car by electric vehicle. Electric utilities expect that the electric vehicle improves the difference between the daytime and nighttime of a recent demand as a new market of electric power demand. There are some reports that indicates on the danger which generates the new peaks as the electric vehicles spread through the market in charging start hour. As the countermeasure for avoiding this problem, the authors propose that 1) inverse load flow by discharging of the contract private use EV is carried out as an energy shift in daytime, 2) the regional charging time shift method is introduced in the midnight charging time zone, in this paper. Therefore, the energy actual consumption of the automobile was investigated, and future demand was predicted by the mathematical consumption modeling. Especially, it is described a strategy of optimum introduction on scheme of effective electric vehicle for energy shift in section 2.2. And authors point out the necessity of market regulation for EV. 14 refs., 10 figs., 1 tab.

    In order to examine the confines of electrical stimulation in layer 2/3 of visual cortex in the brain slice preparation, we estimated the effective range of the stimulation based on the excitatory postsynaptic potential (EPSP) evoked in layer V neuron which receives input from layer 2/3. For this purpose, we recorded and compared EPSPs amplitudes evoked by stimulations at directly over site of recording electrode and lateral site in layer 2/3. Since the EPSP increased linearly with stimulus intensity before the saturation, it was considered that the EPSP correlates with the number of projecting neurons in area directly excited with the stimulation. Then we formed the region model by which we can get the ratios between the neuron numbers in areas excited by different sites stimulations against the stimulus effective ranges. And in the stimulus intensity for action potential threshold of layer 5 neuron, we evaluated the effective range for the relative values of EPSPs to be produced with the stimulations of 250{mu}m lateral site and directory over site. In the model, the ratio increased monotonically with the effective range and in the case of 250{mu}m for the effective range, the ratio between those EPSPs was less than the value in the model. These results led the conclusion that the effective range of the intensity for layer 5 neuron to generate the output is confined within 250{mu}m from directly over site, that is, within layer 2/3. 7 refs., 11 figs., 1 tab.

    Based on the electrical logging data of the existed well and Schlumberger sounding data obtained in 1974, a two-dimensional inversion analysis of the specific resistance profile was conducted at the Akinomiya geothermal field, Akita Prefecture. From the electrical logging data, relationships between the geology and the specific resistance were illustrated. The specific resistance values of basement rocks showed more than 100 ohm-m, which were higher than those of the other seams. Intrusive rocks and tuffs in the basement rocks showed locally low values less than 100 ohm-m. Younger volcanic rocks showed low values around 10 ohm-m. As a result of the two-dimensional inversion analysis, the basement rocks could be detected as high specific resistance layers. Accordingly, it was considered that the basement rocks in this field can be detected as high specific resistance layers by analyzing the results of field survey sufficiently. Low specific resistance zones were observed in the shallow depth, which corresponded to the fumarolic gases. There were some layers with remarkably varied specific resistance values, which were considered to be related with alteration. 6 refs., 3 figs.

    Full Text Available The study of the weathering of two bituminous coals stored at the INCAR stockyard and its influence on coke quality is presented. These coals of similar rank are present in industrial blends used by the Corporación Siderúrgica Integral (CSI for the production of blast-furnace coke. Of all the techniques used to determine the degree of weathering, via thermoplastic properties, Gieseler plastometry was found to be the most sensitive. Coking tests were carried out in the semi-industrial coking plant at INCAR. The effect of weathering on each coal series is completely different. Weathering produces a loss of maximum fluidity accompanied by a decrease in aliphatic hydrogen in both coals. However, the loss rate is different in each case. Coke quality clearly decreases in one, while in the other improves at first but then gradually deteriorates. An improvement in coke quality due to weathering not only affects some high-volatile coals as it is well known but also medium volatile coals.

    Se presenta el estudio de la alteración meteórica de dos carbones bituminosos con contenido medio de materia volátil y de diferente origen geográfico, que han sido almacenados a la intemperie en el Parque del INCAR. Ambos carbones son constituyentes de las mezclas de carbones coquizables utilizadas por la Corporación Siderúrgica Integral (CSI para la producción de coque de horno alto. Entre las técnicas utilizadas para detectar el grado de meteorización de dichos carbones, la fluidez máxima Gieseler es el indicador más sensible para detectar la pérdida de propiedades plásticas. Ambas series de carbones presentan diferente comportamiento frente a la meteorización. Si bien la alteración meteórica provoca una pérdida de fluidez máxima con el tiempo de almacenamiento, debido a una pérdida de hidrógeno alifático en los dos carbones, ésta se produce a diferente velocidad. Estas diferencias se ponen de manifiesto en la calidad de los coques

    This work aims to contribute to a further understanding of the fundamentals of crystallographic slip and grain boundary sliding in the γ-TiAl Ti–45Al–2Nb–2Mn (at%)–0.8 vol%TiB{sub 2} intermetallic alloy, by means of in situ high-temperature tensile testing combined with electron backscatter diffraction (EBSD). Several microstructures, containing different fractions and sizes of lamellar colonies and equiaxed γ-grains, were fabricated by either centrifugal casting or powder metallurgy, followed by heat treatment at 1300 °C and furnace cooling. in situ tensile and tensile-creep experiments were performed in a scanning electron microscope (SEM) at temperatures ranging from 580 °C to 700 °C. EBSD was carried out in selected regions before and after straining. Our results suggest that, during constant strain rate tests, true twin γ/γ interfaces are the weakest barriers to dislocations and, thus, that the relevant length scale might be influenced by the distance between non-true twin boundaries. Under creep conditions both grain/colony boundary sliding (G/CBS) and crystallographic slip are observed to contribute to deformation. The incidence of boundary sliding is particularly high in γ grains of duplex microstructures. The slip activity during creep deformation in different microstructures was evaluated by trace analysis. Special emphasis was placed in distinguishing the compliance of different slip events with the Schmid law with respect to the applied stress.

    Deep rolling is one of the most widely used surface mechanical treatments among several methods used to generate compressive residual stress. This process is usually used for axisymmetric components and can lead to improvements of the surface quality, dimensional accuracy, and mechanical properties. In this study, we deduced the appropriate deep rolling parameters for Al-3vol%SiC nanocomposite samples using roughness and microhardness measurements. The nanocomposite samples were fabricated using a combination of mechanical milling, cold pressing, and hot extrusion techniques. Density measurements indicated acceptable densification of the samples, with no porosity. The results of tensile tests showed that the samples are sufficiently strong for the deep rolling process and also indicated near 50% improvement of tensile strength after incorporating SiC nanoparticle reinforcements. The effects of some important rolling parameters, including the penetration depth, rotation speed, feed rate, and the number of passes, on the surface quality and microhardness were also investigated. The results demonstrated that decreasing the feed rate and increasing the number of passes can lead to greater surface hardness and lower surface roughness.

    Full Text Available Se diseñó, construyó y operó una unidad de electrodiálisis para estudiar experimentalmente la recuperación como ácido acético del acetato producido durante la digestión anaerobia de desechos orgánicos, usando soluciones acuosas de acetato de sodio a diferentes concentraciones (5 g/l, 15 g/l y 30 g/l para simular el licor de fermentación anaerobia. La electrodiálisis se llevó a cabo aplicando 8 diferentes voltajes a la unidad y monitoreando periódicamente el comportamiento de las variables principales del proceso. La tasa máxima de producción de ácido acético lograda fue de 1674 mg/l y se encontró que esta fue proporcional al voltaje aplicado, caudal de licor de fermentación alimentado a la unidad y a la densidad de corriente utilizada. El ácido acético se recuperó en agua destilada y adicionalmente en una solución acuosa de etanol. La electrodiálisis resultó ser una alternativa técnicamente viable en principio, para la producción de ácidos grasos volátiles, pues los resultados obtenidos demuestran que es posible hacerlo con relativa facilidad.

    The load leveling method of batteries for electric vehicles was studied for extension of a battery life and mileage every charging. Under large load fluctuation conditions such as deceleration and acceleration, use of electric power sources other than battery for peek load at acceleration can improve a battery life, output power capacity and mileage every charging. Combination of effective recovery of regenerative power at deceleration with its discharge at acceleration is one of the effective methods. The electric double layer capacitors are serially connected with the batteries, regenerative power is charged only into the capacitors, and both voltages of the battery and capacitor are applied to a power circuit. Battery load is reduced by load on the capacitor. Until the capacitor is re-charged by regenerative power after full discharge, power is supplied only by battery through a diode. Capacitor power is used as effectively as possible until approaching considerably low voltage. As peak load of the battery is reduced by 30%, the mileage increases by 5.7%, and the battery cycle life becomes 1.5 times longer. 7 refs., 5 figs., 3 tabs.

    Full Text Available The term 'Digital Economy' was coined for the first time by Don Tapscott in 1995 in his best-seller The Digital Economy: Promise and Peril in the Age of Networked Intelligence. When he wrote the book 20 years ago, he announced how he thought the Internet would fully transform the nature of business and government. We have now extended the concept, illustrating how digital technologies are rapidly transforming business practices, the economy and societies. Technology, and its impact on business strategy and society, continues to rise in importance. The Digital Economy, sometimes also called “Digital Business” has become a philosophy for many top executive teams as they seek competitive advantages in a world of fast moving technological change. When we talk about digital technologies, we are not only talking about the internet, nor only ICT (Information and Communications Technology, but other concepts such as mobile, telecommunications or content. The digital economy is by no means an exclusively economic concept. Therefore, it might be more appropriate to speak of digital society or digital technology. What matters is that digital is a transverse concept that affects individuals, businesses and public administrations.

    Interaction is an indispensable aspect of data visualization. The presentation of volumetric data, in particular, often significantly benefits from interactive manipulation of parameters such as transfer functions, rendering styles, or clipping planes. However, when we want to create hardcopies of such visualizations, this essential aspect is lost. In this paper, we present a novel approach for creating hardcopies of volume visualizations which preserves a certain degree of interactivity. We present a method for automatically generating Volvelles, printable tangible wheel charts that can be manipulated to explore different parameter settings. Our interactive system allows the flexible mapping of arbitrary visualization parameters and supports advanced features such as linked views. The resulting designs can be easily reproduced using a standard printer and assembled within a few minutes.

  12. Organizations and Strategies in Astronomy Vol. 7

    Science.gov (United States)

    Heck, Andre

    2006-12-01

    This book is the seventh volume under the title Organizations and Strategies in Astronomy (OSA). The OSA series covers a large range of fields and themes: in practice, one could say that all aspects of astronomy-related life and environment are considered in the spirit of sharing specific expertise and lessons learned. The chapters of this book are dealing with socio-dynamical aspects of the astronomy (and related space sciences) community: characteristics of organizations, strategies for development, operational techniques, observing practicalities, journal and magazine profiles, public outreach, publication studies, relationships with the media, research communication, series of conferences, evaluation and selection procedures, research indicators, national specificities, contemporary history, and so on. The experts contributing to this volume have done their best to write in a way understandable to readers not necessarily hyperspecialized in astronomy while providing specific detailed information and sometimes enlightening 'lessons learned' sections. The book concludes with an updated bibliography of publications related to socio-astronomy and to the interactions of the astronomy community with the society at large. This volume will be most usefully read by researchers, editors, publishers, librarians, sociologists of science, research planners and strategists, project managers, public-relations officers, plus those in charge of astronomy-related organizations, as well as by students aiming at a career in astronomy or related space sciences.

    Full Text Available The science of happiness is trans-disciplinary. Happiness is an experience human beings have and, in consequence, its understanding calls for knowledge from all disciplines which, in one way or the other, deal with all facets of human lives. Various disciplines have contributed to the development of the science of happiness; among them: Psychology, Sociology, Economics, Psychiatry and Neuroscience. Because happiness research deals with human being of flesh and blood, it requires high-level techniques to dealing with large information sets in order to extract that information which is relevant. In the study of happiness there are many observations –as many as persons in the world-, there are many variables, and there are many interrelations and synergies to take account of. In consequence, happiness research benefits from sophisticated models that allow for a better understanding of people’s happiness; without losing contact with what real human beings experience, it is important to use techniques that allow researchers to process all the information reaching for valuable conclusions. It is with this purpose that Computer Science has joined the other disciplines providing its calculation powerful tools to advance the study of happiness. It is therefore appropriate that The International Journal of Interactive Multimedia and Artificial Intelligence has decided to launch a special issue on happiness showing some of the potential contributions the discipline can make to happiness research.

    Full Text Available Although Medicine has always been considered a Health Science, today it is not possible to obviate its relationship with other disciplines as Humanities and Basic Sciences. Doctors from everywhere and everyday work with the most sophisticated technology are trying to make their profession more accurate and precise, taking in consideration, at the same time, the human part of their daily labour. In this volume of the Journal, we will try to explore the relation between different medical specialities, basic science and engineering. In fact, modern Medicine requires the participation of these professionals who are involved with doctors in multidisciplinary teams. In this sense, Medical Engineering, is a new degree that is offered in a vast number of Universities along the world. This relationship between Medicine and Sciences can be found in any medical speciality so that, our aim in this volume, is to show different examples of doctors working together with other scientifics in any area of Medical sciences.The volume consists on twelve papers. Each paper explores a particular area of this multidisciplinary approach.

    The Pacific Northwest National Laboratory (PNNL) is evaluating low-temperature technologies to immobilize mixed radioactive and hazardous waste. Three waste forms—alkali-aluminosilicate hydroceramic cement, “Ceramicrete” phosphate-bonded ceramic, and “DuraLith” alkali-aluminosilicate geopolymer—were selected through a competitive solicitation for fabrication and characterization of waste-form properties. The three contractors prepared their respective waste forms using simulants of a Hanford secondary waste and Idaho sodium bearing waste provided by PNNL and characterized their waste forms with respect to the Toxicity Characteristic Leaching Procedure (TCLP) and compressive strength. The contractors sent specimens to PNNL, and PNNL then conducted durability (American National Standards Institute/American Nuclear Society [ANSI/ANS] 16.1 Leachability Index [LI] and modified Product Consistency Test [PCT]) and compressive strength testing (both irradiated and as-received samples). This report presents the results of these characterization tests.
