Abstract (sommario):

Purpose Although new drugs were approved during the 1990s for the treatment of metastatic breast cancer, it is not clear whether their use has changed the outcome of patients in daily practice. This study sought to determine whether survival has improved over time for breast cancer patients who had metastases at diagnosis. Patients and Methods A total of 724 patients have been treated in three French cancer centers for an initially metastatic breast cancer between 1987 and 2000; 343 were diagnosed between 1987 and 1993, and 381 were diagnosed between 1994 and 2000. Tumor characteristics, treatments, and outcomes of these patients were compared by χ2 test, log-rank test, and Cox regression analysis. Results Characteristics were not different between the patients diagnosed from 1987 to 1993 and those diagnosed from 1994 to 2000. Ten percent of patients treated from 1987 to 1994 and 58% of patients treated from 1994 to 2000 have received either a taxane or a new aromatase inhibitor. The 3-year overall survival rates were 27% for patients treated from 1987 to 1993 and 44% for patients treated from 1994 to 2000 (P < .001). The treatment period (1994 to 2000 v 1987 to 1993) was a prognostic factor in multivariate analysis (relative risk, 0.6; P < .001). Conclusion The survival of breast cancer patients presenting with metastases at diagnosis has improved over time. This study strongly suggests that this improvement is related to treatment.

Abstract (sommario):

The conodont genus Teridontus was introduced in 1980 by Miller and was based on the Late Cambrian species Oneotodus nakamurai Nogami, 1967 from the Yencho Member of the Fengshan Fm. of northeast China. Teridontus was later reported from either the Upper Cambrian or Lower Ordovician (Landing et al., 1980; Miller, 1980; Landing and Barnes, 1981; Landing, 1983; An et al., 1983, 1985; Ni et al., 1983; Peng et al., 1983; Nowlan, 1985; Landing et al., 1986; Bagnoli et al., 1987; An, 1987; Buggisch and Repetski, 1987; Pohler and Orchard, 1990; An and Zheng, 1990; Seo and Ethington, 1993; Wang, 1993; Lehnen, 1994; Nicoll, 1994; Seo et al., 1994; Ji and Barnes, 1994; Taylor et al., 1996; Lehnert et al., 1997; Jia, 2000; Dubinina, 2000; Pyle and Barnes, 2002; Zeballo et al., 2005) sediments in numerous localities around the world, but a unanimous interpretation of the composition of the Teridontus apparatus organization was far from accepted.

Resumo: Este trabalho discute o processo de descentralização das políticas educacionais no período de 1987 a 1994. A sua principal abordagem refere-se aos impactos dos conflitos federativos que dominaram este processo. O trabalho apresenta uma interpretação do período que se situa entre a constituição de 1988 e a aprovação da Emenda 14/95 que determina a criação do Fundo de Manutenção e Desenvolvimento do Ensino Fundamental e Valorização do Magistério. As principais conclusões conduziram à percepção de que o processo de descentralização da educação realizou-se em condições de descoordenação nacional e local, com uma dinâmica geral de irracionalidade administrativa e financeira, assentada na competitividade política entre as esferas de governo, levando a resultados administrativos contrastantes com a descentralização desejada. O resultado da análise do perfil da oferta, no período, indica que, se continuassem desenvolvendo-se dentro das tendências verificadas, a maioria dos estados acabariam por conformar um sistema nacional de ensino descentralizado não hierarquizado. As condições gerais do conflito federal e a reação autofágica dos atores federativos dos diferentes sistemas educativos são as referências a partir das quais este trabalho explica o desenvolvimento dos diferentes processos de descentralização nos estados. Os processos de descentralização em contextos de Estados federativos, com autonomia política e financeira dos diferentes entes governamentais, dependem fortemente da adesão dos governos subn.acionais. No entanto, a idéia de descentralização implica a transferência de responsabilidade de um nível de governo' para outro, o que significa que durante um período de tempo as decisões a serem' tomadas envolvem e impactam duas ou mais esferas de governo. Diferentemente da descentralização em estados unitários onde a determinação do nível central é decisiva, nos estados federativos as decisões de um nível de governo superior não necessariamente causam o impacto desejado no nível subnacional. Há necessidade nestes contextos de considerar, tanto as condições históricas dos processos de implementação do federalismo nos Estados estudados, quanto a iniciativa política dos governos centrais que apontam para o conjunto de incentivos que tornaria possível a adesão dos níveis infranacionais.

Abstract (sommario):

In this study, radical socialist articles written on feminism, the feminist movement and the woman question published between 1987 and 1994 in Turkey are examined. The study attempts at describing, classifying and analyzing the Turkish socialist discourse manifested in response to the emergence of feminism in Turkey. It is argued that the Turkish socialists&rsquo
approaches to feminism and the feminists do not differ much, nor a change in their approaches with time can be observed. It is also argued that the theoretical content of the radical socialist articles is usually futile and far from being comprehensive.

O município do Rio Grande-RS foi considerado um marco geoestratégico desde o período colonial, mas a partir da década de 40 começou a perder seu dinamismo, resultando no fechamento de diversas indústrias. Diversos estudos apontam que o processo declinante está ligado à colonização e às atividades produtivas pouco diversificadas. Ao mesmo tempo, os índices socioeconômicos demonstram o desleixo dos governantes para com a cidade mais antiga do estado. O presente trabalho buscou como objetivo central apontar e destacar as políticas públicas de desenvolvimento regional para a recuperação da economia municipal, tendo analisado o período de 1987 a 1994.
The city of the Rio Grande was considered a geostrategic landmark since the colonial period, but from the decade of 40 it started to lose its dynamism, resulting in the closing of diverse industries. Diverse studies point that the declining process is on to the settling and the productive activities little diversified. At the same time, the socioeconomics indices demonstrate the negligence of the governing stop with the city oldest of the state. The present work searched as objective central office to point and to detach the public politics of regional development for the recovery of the municipal economy, having analyzed the period of 1987 the 1994.

Abstract (sommario):

The "essai crepusculaire" was one of the most popular literary genres during the 1980's and 1990's in France. Among those, the essays warning of the impending end of French literature offer a view of the world which idealises the past while condemning a shameful present in order to justify the return of lost values.
Our project consists of an analysis of the argumentative rhetoric contained in the four essays of our corpus, which together form the Discourse on the death of French literature. We studied how the authors set up an argumentative construct likely to convince the reader that French literature has fallen into decay. By analysing the rhetorical processes as well as locating the tacit discourse, we sought to single out the ideology which they promote and to make out the contours of the literary ideal which they delineate. In light of these observations, we ended with the broad outline of a typology of the genre, liable to exemplify all "essais crepusculaires".

Abstract (sommario):

The objective of this paper was to determine the epidemiologic profile of the canine population attended in two veterinary hospitals in Belo Horizonte - MG, Brazil, by the analysis of infomriations in 4.573 clinical records, during period of 1987 to 1994. The results indicate the existence of 51.95% of young dogs; 32,15% mongrel and 53% of males. A large amont of this animal were access by diseases that could be prevented, evidencing the need of education of the owners about the actions of prevention of dog diseases. Although when the data relative to the preventive veterinary medicine in this specie were analysed, we observed rather preocupation of the professional in guide at this respect. The result about the sanitary profile indicated the influence of the climatic conditions on the incidence of some illness, as well as the susceptibility of some breeds and ages. some diseases have similar monthly variation, slowing the existence of feasible comum factor, predisposing their appearing. This indicates that the utilization of information from the clinical records is a valious instrument, since it makes possible the caracterization of the population and the incident of the illness, as well as the identification of the risc factors, providing allowance to the professional actuation.
O presente trabalho objetivou determinar o perfil epidemiológico da população canina atendida em dois hospitais veterinários de Belo Horizonte - MG, a partir da análise de informações colhidas em 4.573 fichas clínicas, no período de 1987 a 1994. Os resultados encontrados indicaram a existência de 51,95% de cães jovens, 32,15% sem raça definida e 53% de machos. Grande parte destes animais foram acometidos por doenças que poderiam ter sido prevenidas, ficando evidente que os proprietários de cães requerem educação nas ações de prevenção de doenças. Entretanto quando analisados os dados relativos a medicina veterinária preventiva nesta espécie, observou-se pouca preocupação dos profissionais em orientar a esse respeito. Quanto ao perfil sanitário, os resultados sinalizaram a influência das condições climáticas na ocorrência de algumas enfermidades, bem como a susceptibilidade de determinadas raças e categorias de idade. Algumas doenças apresentaram variações mensais semelhantes, sinalizando a existência de um possível fator comum, predispondo o aparecimento dessas. Concluiu-se que a utilização das informações provenientes de fichas clínicas e um instrumento valioso, pois possibilita a caracterização da população e da ocorrência das enfermidades, assim como a identificação de fatores de risco, fornecendo importante subsidio para a atuação profissional.

Abstract (sommario):

A method for simulations of the two-dimensional compressible flow in aerodynamically highly loaded turbomachinery on unstructured adaptive grids is presented in this paper. The discretization of the conservative laws in space is executed by the finite volume method. For high efficiency an implicit solution procedure is used. The flux vector of the inviscid flow is calculated by a modified difference splitting method described by Reichert and Simon (1994). To predict the turbulent flow an explicit algebraic stress model in conjunction with k and ε equations is used (Lenke and Simon, 1997). Both for the generation of the initial grid as well as for the grid adaptation the same algorithm is used which is based on the advancing-front method according to Peraire et.al. (1987). For the simulation of high Reynoldsnumber flow within thermal turbomachinery it is most favorable to use quadrilateral elements in the boundary layers in addition to the triangular elements in the main flow region. To adapt the so-called combined grids, some kind of key variables are chosen, e.g. change in total pressure in combination with a shock detector.

Abstract (sommario):

A long term program was initiated in 1987 to develop an electric utility indirect coal-fired gas turbine combined cycle. This initial program was supported primarily by U.S. electric utility organizations and had as a purpose the experimental assessment of a ceramic heat exchanger concept applied as a high pressure gas turbine air heater developed by Hague International. The purpose of the initial phase of the development program was to determine if the ceramic materials, then available for use in the air heater, would withstand the high temperature 2200 F (1204 °C) corrosive environment produced by the combustion of coal. Also, in this initial phase, the program was intended to evaluate means of preventing the fouling of the air heater by fly ash. This experimental work was successful. A second phase of the program to build a 7-MW thermal input prototype was initiated in 1990 under the auspices of a cooperative agreement with the U.S. Department of Energy Morgantown Energy Technology Center (DOE-METC). This work was funded by a consortium of electric utilities, utility organizations, industrial organizations, state agencies, international entities, and the U.S. Department of Energy-METC. New members joined the existing Phase I Consortium to participate in funding the second phase. This second prototype phase is nearing completion and test results are to be available beginning mid-1994. A third, or demonstration phase, of the indirect-fired gas turbine program was selected under the U.S. Clean Coal Technology Program Round V. in May, 1993. This demonstration phase is currently in the planning and preliminary engineering stage. The objective of this proposed demonstration phase is to repower an existing coal-fired power plant in the Pennsylvania Electric Company system at Warren, Pennsylvania (Figure 1). This paper describes the demonstration plant, and the anticipated role of the EFCC cycle in the power generation industry, as well as the performance and economic merits of the Warren repowering concept.

Abstract (sommario):

The conditions for the appearance of cavitation, i.e. the local vaporization of fluid under static or dynamic stresses, are closely connected with the tensile strength of the fluid (Arndt, Keller (1992)). Although the dominant effect of water quality on the cavitation interception has been known for many years (Keller (1981, 1983, 1984)), it is uncommon to measure its stress resistance. A possible reason for that could be the unique stress-resistance probe of Keller (1987, 1994) (Eickmann (1992)), which by itself represents a great engineering break-through, is rather complex and expensive. It has become clear during the ASME/JASME conference in San Francisco, 1999 (Keller, Rott, Striedinger, Awad, Ludwig, Yang, Li), and the Fourth International Symposium on Cavitation in Pasadena 2001 (Keller), that internationally standardized testing conditions are required with respect to water quality (Heller (2000)). A relatively simple method of concurrently measuring tensile strength or cavitation susceptibility in cavitation channels has been developed at the Institute of Fluid Mechanics of the Technische Universita¨t Dresden during the last months. This newly developed tensile strength measuring technique is not only efficient and cheap but can also be installed in any existing cavitation channel with comparably small effort. The presented paper represents the actual developmentstate of the Dresden measuring device. Comparison measurements at the cavitatio n-channels of the Versuchsanstalt Obernach (Dr. Keller), Schiffsbau-Versuchsanstalt Potsdam (Mr. Heinke) and the Schiffsbau-Versuchsanstalt Hamburg (Mr. Friesch) are planed for the following months.

Abstract (sommario):

Advanced prefilming airblast atomizers are widely used for low emission combustors since they deliver a fine spray almost independently of the fuel flow rate. The droplet spectrum produced by this type of atomizer results from the aerodynamic forces at the atomizer edge and from the fuel properties prior to the film disintegration. Therefore, the wall film temperature is an important parameter affecting the fuel properties and in turn the atomization quality. Even though this atomizer type became well investigated (Lefebvre 1989, Rizk et al. 1987, Sattelmayer et al. 1989), still no general quantitative relationship between atomizer design and spray quality could be established since the fuel state at the atomizer edge cannot be precisely predicted yet. In extending earlier experimental and theoretical work on airblast atomizers (Sattelmayer et al. 1989, Himmelsbach et al. 1994, Willmann et al. 1997) and recent advances in the numerical modeling of wall film flows (Rosskamp et al. 1997a), this paper presents a numerical approach to judge the effect of fuel mass flow, air flow and the film length (i. e. length of atomizer lip) on the temperature of the liquid at the atomizer edge. The computer code developed provides detailed information on the wall film flow and the nozzle wall temperature. For the prediction of heat transfer to the film a new model has been developed which is based on measurements of the internal film flow (Elsäßer et al 1997). This new numerical approach can serve as a design tool to evaluate the effects of design modifications during atomizer development with view to their effect on atomization performance. The paper includes the theory for two-phase flow modeling and a generic parameter study that points out that the liquid loading and the length of the atomizer lip are important parameters in atomizer design. The calculations presented in the paper emphasize the necessity of coupled two-phase flow calculations because the film strongly interacts with the gas phase and the predicted atomizer performance is sensitive to changes in the air flow.

Abstract (sommario):

The BR3 plant at Mol in Belgium built at the end of the fifties was the first PWR plant built outside the USA. The reactor had a small net power output (10 MWe) but comprised all the loops and features of a commercial PWR plant. The BR3 plant was operated with the main objective of testing advanced PWR fuels under irradiation conditions similar to those encountered in large commercial PWR plants. The reactor was started in 1962 and shut down in 1987 after 25 years of continuous operation. Since 1989, SCK•CEN is decommissioning the BR3 PWR research reactor. The dismantling of the metallic components including reactor pressure vessel and internals is completed and extensively reported in the literature. The dismantling of auxiliary components and the decontamination of parts of the infrastructure are now going on. The decommissioning progress is continuously monitored and costs and strategy are regularly reassessed. The first part of the paper describes the main results and lessons learned from the reassessment exercises performed in 1994, 1999, 2004 and 2007. Impacts of changes in legal framework on the decommissioning costs will be addressed. These changes concern e.g. licensing aspects, clearance levels, waste management… The middle part of the paper discusses the management of activated and/or contaminated concrete. The costing exercise performed in 1995 highlighted that the management of activated and contaminated concrete is the second main cost item after the dismantling of the reactor pressure vessel and internals. Different possible solutions were studied. These are evacuation as radioactive waste with or without supercompaction, recycling this “radioactive” grout or concrete for conditioning of radioactive waste e.g. conditioning of metallic waste. The paper will give the results of the cost-benefit analysis made to select the solution retained. The last part of the paper will discuss the end goal of the decommissioning of the BR3. In the final decommissioning plan approved by ONDRAF/NIRAS, it was mentioned that the final goal of the BR3 decommissioning will be the “green field” unless opportunities for reuse of the BR3 site will occur during decommissioning. A strategy of partial reuse of the BR3 facility is proposed and being discussed with the main stakeholders. The paper will give the present state of the discussion.

Abstract (sommario):

Because LNG terminals are located increasingly close to shore, the importance of shallow-water effects associated with low-frequency (LF) waves increases as well. The LF wave spectrum in these areas is generally complex, with multiple frequency peaks and/or directional peaks due to LF wave interaction with the shore. Both free and bound LF waves at the same frequency can be present. Since LF waves are potentially very significant for moored vessel motions, it is important to include their effect in an early stage of the terminal design. This requires an efficient and relatively simple tool able to estimate the LF wave spectrum in nearshore areas. The benefit of such a procedure with respect to state-of-the-art response methods is the ability to include the LF free wave distribution in a local wave field in the vessel response calculation. The objectives of the present study are to identify such a tool, and to evaluate the use of its output as input for a vessel motion calculation. Three methods, designed for the determination of wave spectra of free wave-frequency (WF) waves, were applied to artificial LF wave fields for comparison of their performance. Two stochastic methods, EMEP (Hashimoto et al., 1994) and BDM (Hashimoto et al., 1987) and one deterministic method, r-DPRA (De Jong and Borsboom, 2012) were selected for this comparison. The foreseen application is beyond the formal capabilities for which these three methods were intended. However, in this study we have investigated how far we can take these existing methods for the determination of directional LF wave spectra. Sensitivity analyses showed that the EMEP method is the most suitable method of the three for a range of LF wave fields. The reconstructed LF wave spectra using EMEP resembled the input spectra most closely over the whole range of water depths and frequencies, although its performance deteriorated with increasing water depth and wave frequency. Subsequently, a first effort was made to use the information in the reconstructed EMEP LF wave spectrum of a representative shallow-water wave field for a first estimate of the motions of a moored LNG carrier. The results were acceptable. This is a first indication that EMEP output might be used to calculate the motions of an LNG carrier moored in shallow water.

Abstract (sommario):

La presente comunicación traza un recorrido a través de diferentes autores que han realizado series fotográficas basadas en el retrato compuesto fotográfico, por medio de aparatos y dispositivos de imagen o software informático, usados principalmente por los cuerpos de seguridad para recrear el rostro de un individuo a partir del testimonio de otra persona. Desde sus inicios, el retrato compuesto fotográfico ha estado muy relacionado con el interés por descubrir el rostro genérico del criminal, y es una de las principales preocupaciones que muy tempranamente manifestó Francis Galton (1822-1911), pionero en la práctica de la fotografía compuesta. Este tipo de modalidad fotográfica aparece en el ámbito científico que vio nacer a la eugenesia moderna, adquiriendo gran popularidad en la época. Pero es en el último cuarto del siglo XX y sobre todo a principios del presente siglo, coincidiendo con la expansión de la fotografía digital y las herramientas inherentes a la misma, que este tipo de práctica se diversifica en sus formas y su uso, pasando de tener un carácter pragmático, antropológico y fisiognómico, a su producción desde una perspectiva estética y artística. Los distintos aparatos fotográficos que han servido para la construcción de retratos compuestos en el ámbito policial suponen una evolución de los dispositivos surgidos a partir del último cuarto del siglo XIX, como el sintetizador Minolta Montage Unit (Unidad de montaje Minolta), un sistema fotográfico utilizado por la policía en los años setenta que a través de un mecanismo formado por espejos era capaz de mezclar hasta cuatro imágenes y que puede entenderse como una actualización del aparato óptico cercano al estereoscopio desarrollado por el propio Galton, que hacía visible la combinación visual de dos rostros creando así su promedio. O el photoFIT (Técnica de identificación facial fotográfica) impulsado por Jacques Penry, que se basaba en un sistema de fichas fotográficas de cartón intercambiables que se corresponden con distintas partes de numerosos rostros para así poder crear por medio de su combinación el retrato deseado. Un sistema que se ha actualizado con la aparición de distintos softwares informáticos como FACES o FACETTE, en los que se ve una clara referencia a los cuadros sinópticos de características fisonómicas creados por el francés Alphonse Bertillon, unos paneles que conformaban todo un atlas fotográfico de rasgos faciales. Es a partir de estos dispositivos que algunos artistas han producido distintos proyectos fotográficos tomando como punto de partida estas herramientas. Entre ellos cabe destacar las series Andere Porträts (1994/1995) de Thomas Ruff y Opfer (1987) de Clemens Mitscher, que usaron el sistema de la Minolta Montage Unit para generar los retratos promediados; la serie Autoportraits robots (2005) de Leandro Berra y The composites (2012 -) de Brian Joseph Davis que usan como medio principal fotográfico el programa FACES; o la serie Photofit: Self-Portraits (2007) de Giles Reveill y Matt Willey, cuyo proyecto se articula principalmente alrededor del Photofit kit de Jacques Penry.
