Towards Behavioral Reflexion Models  

NASA Technical Reports Server (NTRS)

Software architecture has become essential in the struggle to manage today s increasingly large and complex systems. Software architecture views are created to capture important system characteristics on an abstract and, thus, comprehensible level. As the system is implemented and later maintained, it often deviates from the original design specification. Such deviations can have implication for the quality of the system, such as reliability, security, and maintainability. Software architecture compliance checking approaches, such as the reflexion model technique, have been proposed to address this issue by comparing the implementation to a model of the systems architecture design. However, architecture compliance checking approaches focus solely on structural characteristics and ignore behavioral conformance. This is especially an issue in Systems-of- Systems. Systems-of-Systems (SoS) are decompositions of large systems, into smaller systems for the sake of flexibility. Deviations of the implementation to its behavioral design often reduce the reliability of the entire SoS. An approach is needed that supports the reasoning about behavioral conformance on architecture level. In order to address this issue, we have developed an approach for comparing the implementation of a SoS to an architecture model of its behavioral design. The approach follows the idea of reflexion models and adopts it to support the compliance checking of behaviors. In this paper, we focus on sequencing properties as they play an important role in many SoS. Sequencing deviations potentially have a severe impact on the SoS correctness and qualities. The desired behavioral specification is defined in UML sequence diagram notation and behaviors are extracted from the SoS implementation. The behaviors are then mapped to the model of the desired behavior and the two are compared. Finally, a reflexion model is constructed that shows the deviations between behavioral design and implementation. This paper discusses the approach and shows how it can be applied to investigate reliability issues in SoS.

The reflexion coefficient as a measure of transepithelial permeability in the isolated rabbit pancreas.  

PubMed Central

1. The reflexion coefficients of a number of non-electrolytes and electrolytes have been determined in the isolated rabbit pancreas. 2. The reflexion coefficients of the following non-electrolytes were: urea, -0.02; glycerol, 0.06; erythritol, 0.11; sorbitol, 0.41; mannitol, 0.42; arabinose, 0.72; xylose, 0.74, assuming a value of 1.00 for sucrose. 3. These values are equal within the experimental error to values previously obtained with a tracer technique for the same preparation, but they are significantly lower than those reported by other investigators for the isolated perfused cat pancreas. 4. Addition of 100 mM-sucrose to the bathing medium resulted in proportionally increased Na+ and K+ concentrations in the secreted fluid. The secreted fluid remained isotonic with the bathing medium under all circumstances. 5. Addition of 10(-5) M-carbachol to the bathing medium led to a reduction in the reflexion coefficient of sucrose from 1 to 0.85, but only when 25 mM-sucrose was used. 6. The reflexion coefficients of electrolytes were: NaCl, 0.50; KCl, 0.51; NaHCO3, 0.52 and choline chloride, 1.02. 7. It is concluded that the isolated rabbit pancreas is highly permeable, both to electrolytes and to small non-electrolytes, probably being more leaky than any other epithelium studied so far.

[Reflexions about aging and work].  

PubMed

This qualitative research has the aim to know the meaning of the aging process in the work market referring to the aged people. Six aged persons have participated in this research. The data were collected through an interview and were analyzed using the technique of thematically analyze. Three analytical categories emerged: the meaning of aging/to be aged; the meaning of work; the meaning of aging in the work. Concluding, this paper reinforces the theory that the capitalist societies attach excessive value to the work in the human being life. When it isn't into the life--because of the retirement or the unemployment--it compromises the quality of aging/to be aged of the person, mainly if skills and (individual, social and economical) conditions will lack participation and priority to others activities and values in her/his life.

Sobre el estado evolutivo de ? Pictoris  

NASA Astrophysics Data System (ADS)

Desde el descubrimiento de fuertes excesos infrarrojos en ? Pictoris, esta estrella ha sido muy estudiada y es considerada candidata a poseer un sistema planetario propio. ? Pic está rodeada de un disco asimétrico de polvo que se observa de canto y que esta vacío a distancias <= 40 AU. Esto se considera una fuerte evidencia en favor de la presencia de (al menos) un planeta gigante. Recientemente se han observado líneas de material circunestelar que se han interpretado como consecuencia de la caída de objetos cometarios sobre esta estrella. Recientemente se ha utilizado la existencia del disco de polvo para atribuir una edad corta (pre - secuencia principal) a ?Pic. Sin embargo, la evaporación de estos cometas provee suficiente polvo como para explicar la presencia del disco observado sin necesidad de edades cortas. En este trabajo mostramos que la comparación entre la tasa de impactos cometarios estimada en el Sistema Solar para diferentes etapas de su evolución y los datos observados en ? Pic indica edades avanzadas para ? Pic. Esta estimación debe tomarse con cautela ya que depende de la estructura de los sistemas planetarios. Además mostramos que, desde el punto de vista de la evolución estelar y con las incertezas presentes en la luminosidad y la temperatura efectiva, existe un continuo de edades posible para ? Pic. Sin embargo, empleando los datos provenientes de los flujos cometarios encontramos que una edad prolongada es consistente con ambos tratamientos.

Sobre a largura da última superfície de espalhamento  

NASA Astrophysics Data System (ADS)

De acordo com o modelo do "Big-Bang", no universo primordial a matéria estava em equilíbrio térmico com a radiação. Com a expansão a temperatura da radiação cai. Quando a temperatura chega em torno dos 4.000K, os espalhamentos diminuem, começando a recombinação dos prótons e elétrons em Hidrogênio neutro (era conhecida como da recombinação). Ao final da recombinação, os fótons se propagam livremente sofrendo, em princípio, somente os efeitos do "redshift" cosmológico. Esses fótons nos alcançam hoje como a radiação cósmica de fundo (RCF), e parecem vir de uma superfície esférica ao nosso redor, tal que o raio dela é a distância que ele viajou desde seu último espalhamento na época da recombinação. Naturalmente, esse processo não ocorreu abruptamente, implicando na existência de uma largura no espaço dos "redshifts" que deve depender do modelo cosmológico específico e dos processos físicos considerados. Neste trabalho analisamos os efeitos de diferentes modelos - a saber, aqueles com decaimento do vácuo L(t), criação de matéria, quintessência e gás de Chaplygin - sobre a última superfície de espalhamento da RCF, em particular sua largura e a função visibilidade, que determina a probabilidade de um fóton ter tido seu último espalhamento num "redshift" z. No caso particular dos modelos com decaimento do vácuo, existe uma forte dependência da função visibilidade com L(t). Tais efeitos poderão ser testados através da análise dos resultados de experimentos mais precisos que estão atualmente em andamento, como por exemplo, o WMAP.

[Some criminological and psychopathologic reflexions about serial crimes].  

PubMed

This article reviews the concept of serial crime, including murder as well as any action for the purpose of inflicting bodily harm upon any person. It characterizes three types of multi-murderers: serial killers, mass murderers, and spree killers. These offenders often have a specific (ritual) behavior that is idiosyncratic and repeated on each crime, which allows the psychological profiling of the murderer. Examples, a psychopathological background, and a description of both their criminal behavior and dynamics are provided for each of these criminals. They are further classified according to their different motivations: psychotic, prophetic or enlightened, pleasure, secondary or pecuniary profits, power or control. Finally, the author shares his personal experience over 20 years in the assessment of sexual offenders. PMID:22091451

Reflexions on the identity and the practice of child psychiatry.  

PubMed

?he issue of the professional identity is salient for any medical discipline but especially for these, like child psychiatry and perhaps psychiatry, where the professional is the principal "instrument" in the assessment and in providing interventions. The Ericksonian view on identity implies self-sameness, continuity and synthesis which the child psychiatry as a specialty and child psychiatrists as professionals are to achieve more or less successfully. As a professional, the child psychiatrist is directed to the prevention, diagnosis and treatment of psychiatric disorders and associated problems in children and adolescents viewing children as developing biopsychological entities being in ongoing co-influencing interaction with their immediate and wider societal contexts. As a discipline, child and adolescent psychiatry needs to integrate developmental biological and psychological aspects, and holistic child-centered and family-focused perspectives. Child psychiatry is to integrate not only various aspects of the child as individual and of his environments as they are, but also in their diachronic dimension. As child psychiatrists, in my view, we must keep integrated in our professional armamentarium the consideration for intra- and interpersonal processes. In that perspective, of special value is the appreciation of setting, of timing, and of interpersonal processes in their interaction with intrapersonal ones. In addition, being both child-centered and family-focused, we need a systemic literacy to look at the families and of children as part of them. Apart from evidence-based information and clinical skills, we need some mature attitude to helpfully use our knowledge and skills. This attitude can transcend the state of the art professional algorithms; rather it integrates and not just imitates them. It cautions against too much enthusiasm in following the pendulum. It implies awareness of some reasonable limit to the urge to change the children and families. In fact, many developmentally and behaviorally disabled children need not only attempts to correction, but also some help to live and develop more successfully with their handicaps. Here, if not everywhere, a facilitating discovery and building on patient's personal assets professional approach is needed. The international integration of "child psychiatries" of different countries and world's regions is valuable, and not only with reference to elaborating on and further developing child psychiatry as a theory and practice, but in the view of international co-support, which being almost everywhere under-served child psychiatry and its potential patients-children, adolescents and families-necessitate.

Earthquakes in the context of the natural and man-made events. An epidemiologic reflexion  

NASA Astrophysics Data System (ADS)

In the last few years a great interest has been growing for studying, in a detailed way, the impact of natural and man-made disasters, by quantifying their consequences on the human community. Such interest could only be possible due to the easier way the information circulates nowadays and how it can be made available to interested persons. We consulted a few elements of published information from a wide variety of sources and compared with elements gathered by ourselves. Many consulted results are taken from the insurance industry, especially from recent years; others from books or through the internet. A brief discussion on the kind of quality that the information should exhibit is made for a few cases. Earthquakes are analysed in the context of natural and man-made disasters, and statistics are shown for the 20th century, with greater emphasis in its second half. Data refers mainly the number of events, classifying them, number of deaths, injuries and homeless, and economic direct impact. In many instances the values by different sources present large uncertainties, especially in what concerns the economic impact. Time evolution is viewed considering the growing of population, housing and industry and the implementation of seismic codes. More precise data from recent years are used to confront the numbers referring larger periods of time. Comparisons are established among the various types of events at the world and regional levels, in order to define an index for the perception of risks. A recommendation for the setting common databases at the international level with this data is strongly made in order to reduce uncertainties and cover more wide fields of information

Reflexion Mössbauer analysis of the in situ oxidation products of hydroxycarbonate green rust  

NASA Astrophysics Data System (ADS)

The purpose of this study is to determine the nature of the oxidation products of FeII-III hydroxycarbonate FeII4FeIII2(OH)12CO3·3H2O (green rust GR(CO32-)) by using the miniaturised Mössbauer spectrometer MIMOS II. Two Mössbauer measurements methods are used: method (i) with green rust pastes coated with glycerol and spread into Plexiglas sample holders, and method (ii) with green rust pastes in the same sample holders but introduced into a gas-tight cell with a beryllium window under a continuous nitrogen flow. Method (ii) allows us to follow the continuous deprotonation of GR(CO32-) into the fully ferric deprotonated form FeIII6O4(OH)8CO3·3H2O by adding the correct amount of H2O2, without any further oxidation or degradation of the samples.

[Reflexions about the curricula at the faculty of medicine in the XXI century].

In this paper we review the main medical programs from the Universidad Nacional Autonoma de Mexico (UNAM) faculty of medicine in the first seventy-five years of twentieth century. We have selected those instances that are representative of special moments in the development of Mexican medical knowledge, and also corresponding to the need to prepare medical students in view of social demands. The first programs are those of Ignacio Chavez in 1934, concerned mainly with the introduction into the curricula of medical specialties such as cardiology or neurology. After those, the 1956 and 1960 programs are mentioned and briefly analyzed; both were founded on the concern to develop a clinical reasoning in the student. Finally, the 1974 Integral General Medicine Program directed its interest to social and environmental themes. PMID:21527967

[Cranial asymmetries. Reflexions on plagiocephalies. Premature sutural synostosis or extracranial origin?].  

PubMed

The authors relate a clinical and radiological (X Ray and TDM tridimensional) study with an anthropological (dry skulls) study of plagiocephaly. The aim is to find with the aid of a physical examination, some anatomic parameters which permit to differentiate cranial asymmetry with coronal premature synostotic suture from functional deformation with extracranial outset. The term plagiocephaly is used to define forehead asymmetry. It is necessary to study orbital rim, nasal root, malar eminence, ear and chin mid point position. The morphology of the skull is important to look: frontal flattering and also occipital flattering or bulging, contra-lateral frontal and pterional aera bulging. The authors conclude that a single parameter is necessary to differentiate the two kinds of plagiocephaly: the petrous bone position on the flattened frontal side: sagittalisation: fonctionnal plagiocephaly; frontalisation: synostotic plagiocephaly.

Problems in rehabilitation elicited the search for a new meaning in life. In analysing and interpreting the brain injury, preterm birth played a crucial role. The theme of lifelong compensation of deficits, caused by preterm birth, gained new importance. The consequences of brain injury left unsuccessful his former modes of compensation. He was confronted with finding new strategies in order to counterbalance the growing decompensation.

Left-Deviating Prism Adaptation in Left Neglect Patient: Reflexions on a Negative Result  

PubMed Central

Adaptation to right-deviating prisms is a promising intervention for the rehabilitation of patients with left spatial neglect. In order to test the lateral specificity of prism adaptation on left neglect, the present study evaluated the effect of left-deviating prism on straight-ahead pointing movements and on several classical neuropsychological tests in a group of five right brain-damaged patients with left spatial neglect. A group of healthy subjects was also included for comparison purposes. After a single session of exposing simple manual pointing to left-deviating prisms, contrary to healthy controls, none of the patients showed a reliable change of the straight-ahead pointing movement in the dark. No significant modification of attentional paper-and-pencil tasks was either observed immediately or 2 hours after prism adaptation. These results suggest that the therapeutic effect of prism adaptation on left spatial neglect relies on a specific lateralized mechanism. Evidence for a directional effect for prism adaptation both in terms of the side of the visuomanual adaptation and therefore possibly in terms of the side of brain affected by the stimulation is discussed.

Imagerie par contraste en reflexion ou transmission lors d'une procedure par laser au dioxyde de carbone  

NASA Astrophysics Data System (ADS)

The use of laser micromachining is now reaching maturity. Laser micromachining is now competing with traditional methods in procedures such as welding, cutting or melting. This thesis will focus on various aspects of the uses of laser in the industry. In each aspect we are drawing our attention on the method to image a given procedure in real-time. In this manuscript we are applying Maxwell's equations to describe the propagation of an electromagnetic wave across various interfaces between media. The approach is tantamount to using Fresnel equation by taking into account the thickness between two successive interfaces bounding a given medium. This theory becomes useful when investigating the evaporation of matter, welding of two dissimilar materials and etching at the surface of a substrate. The progression of welding and etching will be imaged in real-time using an effect of contrast. Various planes of observation that are available in our set-up will allow us to draw firm conclusions in real-time as the procedure develops. Using the principle of contrasting regions it was found that the progression of a laser procedure can be imaged and give interesting details as it evolves in time. It will be also possible to determine when it is time to stop the operation during a laser procedure when a substance evaporates on a substrate. In the case of a laser welding procedure, it will be shown that the imaging method can give some information about the quality of a weld between two different materials. Lastly, it will also be shown that we can image a laser etching procedure by using the contrast of reflectance in neighbouring regions.

Sobre las edades de las componentes del sistema PSR B1855+09  

NASA Astrophysics Data System (ADS)

In the last few years several low-mass white dwarfs (helium white dwarfs, He WD) have been detected as companions to millisecond pulsars. In this kind of systems, pulsar emission is activated by mass transfer episodes, which also lead to the formation of the He WD, thus if we set the zero age point at the end of this mass loss transfer episodes, the ages of both objects should be the same. In this sense, PSR B1855+09 system casts some doubts about the correctness of theoretical white dwarf models. The age of the pulsar inferred from its spin-down rate is 5 Gyr. However, existing determination of the mass of the white dwarf companion of this system and recent optical detection of it, which has allowed to infer its effective temperature, have led to an estimative age of 10 Gyr for the white dwarf. Noteworthly, available theoretical calculations used to infer the cooling age of the He WDs, neglect element diffusion. In this work, we present evolutionary calculations for He WDs taking into account the effects of gravitational settling, and chemical and thermal diffusion in a self consistent way, and in particular we use the results to determine cooling ages for He WDs. We find that models within the mass range 0.19 <= M/Msolar <= 0.41 suffer from diffusion-induced thermonuclear flashes, during which an appreciable amount of the hydrogen of the envelope is burnt. Only after the hydrogen envelope has been reduced enough so as not to be able to produce another thermonuclear flash, He WD models evolve towards their final cooling track. During this evolutionary stage, cooling rate is determined by whether stable hydrogen burning is relevant or not. We find that diffusion-induced thermonuclear flashes reduce the hydrogen envelope so as to prevent stable hydrogen burning from being an appreciable source of energy for the models, which are then forced to a rapid cooling. In this way, expected ages for these objects are drastically reduced when compared to the case in which diffusion is neglected (as these models predict thick hydrogen envelopes and thus, a cooling stage dominated by stable hydrogen burning). In particular, we find for the white dwarf companion to PSR B1855+09 an age of 4±2 Gyr, which is in very good agreement with the spin-down age of this pulsar and also shows that the age discrepancy previously found is due to an oversimplification in the physical ingredients of theoretical models.

Efecto de las colisiones sobre el Plano Fundamental de bulbos de galaxia espirales  

NASA Astrophysics Data System (ADS)

The main aspects of the Fundamental Plane (FP) relation for ellipticals and early type bulges can be explained assuming the virialization of the systems, however, the observed dispersions are larger than instrumentation errors and have been thought to have physical basis. Even more, it is expected that the scatter and the position that different objects ocupy on it, could give clues on the mechanisms of galaxy formation and on the evolutionary path of galaxies. The FP relation has been observed and confirmed in the local Universe and it has been recently estimated for galaxies at intermediate redshifts. However, these estimations are based on a low statitical number and effects such as the evolution of the stellar populations and the presence of dust may introduce additional dispersion. Scannapieco & Tissera (2003) studied the mass distribution of disk systems and the way in which this distribution is modified by mergers. These authors have used numerical simulations which included gravitation, hydrodynamics, cooling and stellar formation in a cosmological frame work. As a consecuence, the collision parameters and the physical features of the simulated objects are the result of the consistent formation of the structure in a hierarchical scenario. The results show that depending on the caracteristics of the potential well, some systems may suffer gas inflows as a result of tidal fields during the orbital decay of the satellite system. This gas inflow originates a star burst previous to the fusion (i.e. secular evolution) which tends to form bulges with exponential profiles. In this work we present preliminary results on the effects of mergers on the FP defined by bulges. We found that the simulated bulges determines a FP in agreement with observations. We have detected that the mergers could significantly affect the FP depending on the internal properties of the galactic systems. And, particularly, secular evolution is found to play a critical role in the determination of a FP with the observed slope (Smith Castelli et al., 2004, in preparation).

Profesionalismo: Un estudio fenomenologico sobre experiencias de universitarios en programas de salud  

NASA Astrophysics Data System (ADS)

Some studies suggest that, upon admission, medicine programs students display eagerness for community service, aspirations to be useful, and to contribute to society's well-being. Those same studies reflect that qualities of idealism, moral nature, and internal motivation, suffer a subsequent diminishing. The researchers inferred that the main reason for this process of change in the mood and disposition of these future physicians lies in the modeling they receive from medical professionals throughout clinical learning activities, by way of behavior and relationships exhibited during daily interaction with peers, patients and the students themselves. This phenomenological study used a cross-sectional sample to explore the experiences of future health workers as they went through didactic and clinical phases of their training curriculum. The study employed semi-structured interviews and reflective journals to explore those experiences and to discover the meanings ascribed by the participants. The analysis revealed that the students defined "professionalism" in terms of scientific knowledge, commitment, respect for human dignity, comradeship, courtesy, empathy, integrity, altruism, motivation. They also described their feelings as they went through the didactic and clinical experiences, and recognized as very important the extracurricular activities of community service, describing them as useful opportunities which contributed to understand their work in terms of a mission dedicated to the achievement of the social benefit. From their individual perspectives, the clinical environment could, in general, be described as congruent with those characteristics of professionalism. During the study we had the opportunity to share, in a little deeper way, the environment... the world... of this small group of young students as we went on trying to decipher their feelings and thoughts. At the end, we realized the richness of their sensibilities, we perceived the intensity of their moral and ethical convictions, we were able to understand their concerns, worries, struggles and efforts. This life event had profound and significant repercussions in our personal and professional life. As a result, and from now on, we will no longer look at our young scholars and apprentices without imagining a noble spirit, with goals which at times could seem unattainable... without completely visualizing or conceiving real hope for a better country.

Electron Diffraction Evidence for the Ordering of Excess Nickel Atoms by Relation to Stoichiometry in Nickel-Rich Beta'-Nial Formation of a Nickel-Aluminum (Ni2al) Superlattices  

NASA Technical Reports Server (NTRS)

In electron diffraction patterns of nickel-rich beta-NiAl alloys, many anomalies are observed. One of these is the appearance of diffuse intensity maxima between the reflexions of the B2 structure. This is explained by the short-range ordering of the excess nickel atoms on the simple cubic sublattice occupied only by aluminum atoms in the stoichiometric, perfectly ordered NiAl alloy. After annealing Ni 37.5 atomic percent Al and Ni 37.75 atomic percent Al for 1 week at 300 and 400 C, the diffuse intensity maxima transformed into sharp superstructure reflexions. These reflexions are explained by the formation of the four possible variants of an ordered hexagonal superstructure corresponding to the Ni2Al composition. This structure is closely related to the Ni2Al3 structure (same space group) formed by the ordering of vacancies on the nickel sublattice in aluminum-rich beta-NiAl alloys.

Teorí­as de primer y segundo orden sobre el potencial de ciertas figuras de equilibrio de cuerpos celestes  

NASA Astrophysics Data System (ADS)

Uno de los problemas que aborda la Mecánica Celeste es la determinación de las figuras de equilibrio de los cuerpos celestes. Para investigar su solución mediante métodos directos, se precisa evaluar el potencial generado por su autogravitación, el generado por su fuerza centrí­fuga y el generado por la fuerza de atracción entre los cuerpos. Los métodos clásicos de Finlay y Kopal que afrontan estos problemas, para determinar el potencial autogravitatorio en las configuraciones de equilibrio, emplean desarrollos en serie de los potenciales interior y exterior del potencial autogravitatorio. Estos métodos incurren en el error de suponer la convergencia en capas donde resulta cuestionable dicha convergencia para estos desarrollos en serie. En este trabajo se han elaborado unos algoritmos que contemplan toda la casuí&stica y que permiten una manipulación efic iente del producto de polinomios de Legendre, del producto de funciones asociada s de Legendre y del producto de armónicos esféricos como combinacióon lineal de ellos mismos, respectivamente. Se han obtenido, para primer y segundo orden en las amplitudes, los desarrollos correctos para los potencial es interior y exterior del potencial autogravitatorio para configuraciones de equilibrio aisladas, y , en primer orden de amplitudes, los mismos potenciales para los sistemas binarios próximos. Se ha elaborado un método analítico, en primer orden respecto de las amplitudes, para la determinación del potencial de marea en sistemas binarios próximos en el cual se manifiesta la forma de la componente secundaria del sistema

The role of charge density waves in structural transformations of 1T TaS2  

Microsoft Academic Search

Electron and X-ray diffraction studies have identified three metastable phases in 1T TaS2. Extra reflexions are interpreted as arising from charge density waves coupled to periodic distortions modulating a trigonal lattice. These waves are incommensurate with the matrix in 1T1 and 1T2, but form a commensurate super-lattice in 1T3. Within 1T2, the temperature dependence of the wave vector is correlated

Vínculos sobre um modelo de quartessência de Chaplygin usando observações do satélite chandra da fração de massa de gás em aglomerados de galáxias  

NASA Astrophysics Data System (ADS)

Observações de Supernovas do tipo Ia mostram que a expansão do Universo está acelerando. Segundo as equações de Einstein uma componente com pressão negativa (energia escura) é necessária para explicar a aceleração cósmica. Além da energia escura é usualmente admitido que no Universo há também uma matéria exótica com pressão zero, que é chamada de matéria escura. Essa componente possui um papel fundamental na formação de estruturas no Universo. Recentemente tem se explorado a possibilidade de que matéria e energia escura poderiam ser unificadas através de uma única componente, que tem sido denominada de quartessência. Um exemplo de fluido com essas características é o Gás de Chaplygin Generalizado, que possui uma equação de estado da forma p = -A/ra. Inicialmente consideramos o caso especial a = 1 (gás de Chaplygin) e vinculamos parâmetros do modelo utilizando observações em raios-X do satélite Chandra da fração de massa de gás em aglomerados de galáxias. Uma comparação dos vínculos obtidos com esse teste com outros testes, tais como supernovas e idade do Universo, mostra que esse teste é bastante restritivo. Exibiremos ainda resultados para o caso em que a curvatura é nula e o parâmetro a está compreendido no intervalo -1 < a 1.

[Actividad inhibitoria de dihidroxifenil propenona sobre betalactamasas de Enterobacter cloacae: estudio preliminar en el desarrollo de fármacos para enfrentar la resistencia bacteriana].  

PubMed

Introduction: Enterobacter cloacae is a pathogenic microorganism with the ability to produce betalactamase enzymes, which makes them resistant to betalactamic antibiotics. Additionally, the limited activity of enzymatic inhibitors has been identified, and, therefore, the design of new drugs and the promotion of their rational use are the only possibilities to overcome this problem. Objective: The aim of this research was to evaluate the effect of dihydroxy-phenyl-propenone on a clinical isolate of E. cloacae , as well as its activity on a betalactamase isolated from this resistant microorganism in order to contribute to the search for new betalactamase inhibitors. Materials and methods: Dihydroxy-phenyl-propenone chalcone was synthesized and evaluated on a clinical isolate of E. cloacae to determine the minimum inhibitory concentration by broth microdilution; once the betalactamase enzyme was purified by affinity chromatography, a spectrophotometric analysis was done to evaluate its kinetic activity. Results: The minimum inhibitory concentration value of dihydroxy-phenyl-propenone on E. cloacae was 35 µg/ml; the recovery percentage of the betalactamase from the microorganism was 31.75% and the kinetic parameters were V max =1.7 x 10 -3 µM/min and K M = 2330 µM, which show an important inhibitory activity. Conclusion: Dihydroxy-phenyl-propenone has shown inhibitory activity on betalactamase enzymes and the ability to protect the chemical integrity of betalactamic antibiotics; this synergistic effect turns it into a promising compound in the search for new alternatives to overcome bacterial resistance.

Sistema de cúmulos globulares de la galaxia lenticular NGC 6861: en busca de indicios sobre la formación de las S0s.  

NASA Astrophysics Data System (ADS)

We present a preliminar photometric study of the globular cluster system (GCS), associated to the lenticular galaxy (S0) NGC 6861, which is located in a low density environment (d˜31.8 Mpc). It is based on GEMINI/GMOS images (GS-2010B-Q-2: PI Lilia P. Bassino) in the filters g', r', i' of three fields, one of them centered in the galaxy. We find a large number of GCs candidates and detect the presence of at least two sub-populations of GCs (``blue''/metal-poor and ``red''/metal-rich). The spatial distribution of ``red'' candidates presents a higher concentration toward the galaxy (associated to the bulge?), while the distribution of ``blue'' candidates is more homogeneus over the three fields (associated to the halo?). In the color-magnitud diagram, the ``blue'' GC candidates show a possible mass-luminosity relation, known as ``blue-tilt'', probably detected for the first time in a lenticular galaxy.

Quantitative FT-IR spectroscopy of gypsum raw material for industry  

NASA Astrophysics Data System (ADS)

Today quality control (QC) is a big issue for being competitive in the gypsum industry. Knowledge and understanding of the raw material help to enhance the quality and permanence of products. Therefore a rapid, precise and user-friendly FT-IR spectroscopic method for quantitative analysis of gypsum, anhydrite, magnesite and dolomite from the gypsum deposit of Puchberg, Austria is being developed. There are decisive advantages of FT-IR spectroscopy compared to thermogravimetric methods (TG, DTA, DSC) or XRD, which are commonly used for QC, e.g. it is frequently available in industry labs and a spectrum can be obtained in a few minutes, with a minimum of sample preparation. The effects of particle size and ratio of dilution with KBr were investigated in transmission mode, using KBr pellets, as well as in diffuse reflexion mode. Little differences in particle size lead to enormous differences in peak height in transmission mode, but show only little effects in diffuse reflexion. The small amounts of sample used in KBr pellets (e.g. 2 mg sample : 500 mg KBr) also turned out to be disadvantageous, just like the time consuming sample preparation. Measurements in diffuse reflexion with a sample to KBr ratio of 1:10 show promising results for use in standardization, whereas higher dilutions hardly improve the quality, and ratios of 1:5 still show components of specular reflection. The calibration model for quantitative analysis is being constructed measuring various defined mixtures of >98% pure natural minerals (gypsum, magnesite, dolomite), and synthetic materials (anhydrite). The latter was obtained by heating gypsum at 350^oC for 10 h. The synthetic material was chosen, because natural material was not available in sufficient amounts with high purity. The IR method is compared with results achieved with XRD-Rietveld and thermogravimetric methods. Advantages of chemometrical software based on multivariate statistical techniques will be investigated and compared with standard techniques using simple peak fitting methods.

Toward a critical ethical reflexivity: phenomenology and language in Maurice Merleau-Ponty.  

PubMed

Working within the tradition of continental philosophy, this article argues in favour of a phenomenological understanding of language as a crucial component of bioethical inquiry. The authors challenge the 'commonsense' view of language, in which thinking appears as prior to speaking, and speech the straightforward vehicle of pre-existing thoughts. Drawing on Maurice Merleau-Ponty's (1908-1961) phenomenology of language, the authors claim that thinking takes place in and through the spoken word, in and through embodied language. This view resituates bioethics as a matter of bodies that speak. It also refigures the meaning of ethical self-reflexion, and in so doing offers an alternative view on reflexivity and critique. Referring to the Kantian critical tradition and its reception by Hannah Arendt and Michel Foucault, we advance a position we call 'critical ethical reflexivity'. We contend that Merleau-Ponty's phenomenology of language offers valuable insight into ethical reflexivity and subject formation. Moreover, his understanding of language may foster new qualitative empirical research in bioethics, lead to more nuanced methods for interpreting personal narratives, and promote critical self-reflexion as necessary for bioethical inquiry.

In situ control of roughness of processed surfaces by reflectometric method  

NASA Astrophysics Data System (ADS)

It is demonstrated that the removal rate in polishing optic materials decreases exponentially with increasing bond energy in these materials and the polished surface roughness depends on the ratio of natural frequencies of molecular fragments on the tool and workpiece surfaces. The dependences of polished surface roughness on the slime particle size, permit an optimal choice of powders for a bound-abrasive polishing tools, which will ensure a required polished surface quality. The dependences of the polished surface microprofile parameters on the coordinate of a zone under study, which were described by periodic functions, do represent the effects that occur in the tool-workpiece contact zone. The optical monitoring system, the device for giving of the technological environment in a zone of contact of the tool and a processed detail and a technique of adjustment of the machine tool for finishing processing of precision optic surfaces are described. The relation of intensity of the beam reflected from a surface, to intensity of a falling beam allows to estimate a reflexion index in situ. Increase of reflexion index in process of roughness decrease is established. Possibility of active quality assurance of precision surfaces in the course of processing is shown.

Atmospheric correction in presence of sun glint: application to MERIS.  

PubMed

The sun glint is a major issue for the observation of ocean color from space. For sensors without a tilting capacity, the observations at sub-tropical latitudes are contaminated by the bright pattern of the specular reflexion of the sun by the wavy sea surface. Common atmospheric correction algorithms are not designed to work in these observation conditions, reducing the spatial coverage at such latitudes by nearly a half. We describe an original atmospheric correction algorithm, named POLYMER, designed to recover ocean color parameters in the whole sun glint pattern. It has been applied to MERIS data, and validated against in-situ data from SIMBADA. The increase of useful coverage of MERIS measurements for ocean color is major, and the accuracy of the retrieved parameters is not significantly reduced in the presence of high sunglint, while, outside the sunglint area, it remains about the same as by using the standard algorithm.

Ray trace algorithm description for the study of pump power absorption in double clad fibers  

NASA Astrophysics Data System (ADS)

An algorithm for the analysis of the double clad fiber design is presented. The algorithm developed in the MATLAB computing language, is based on ray tracing method applied to three-dimensional graphics figures which are composed of a set of plans. The algorithm can evaluate thousands of ray paths in sequence and its corresponding pump absorption in each of the elements of the fiber according to the Lambert-Beer law. The beam path is evaluated in 3 dimensions considering the losses by reflexion and refraction in the faces and within the fiber. Due to its flexibility, the algorithm can be used to study the ray propagation in single mode or multimode fibers, bending effects in fibers, variable geometries of the inner clad and the core, and could also be used to study tappers.

We realized that it is essential that the patient who has an auto injector also has the direction sheet in its emergency bag. Patients, families but also young medical doctors' remarks and reflexions led us to create an explanatory didactic, precise, illustrated and practical direction sheet. The goals are to gather succinct information about the patient (personal contact information, medical history); remind emergency numbers (15 or 112) and the emergency treatment (antihistamine, broncholitor if necessary, epinephrine shots). It also indicates step by step how to use the auto injector (Anapen) and emphasizes the need for a medical supervision if the shot has been used. We present this direction sheet and the way to use it. PMID:15137481

[Depression, culture and evil].  

PubMed

The author has written this article as a reflexion on the relation between depression and guilt feelings by comparing her clinical experience-acquired in a western context-to knowledge gained from psychiatric anthropology studies. Manifestations of suffering are different according to different cultural contexts; in the western world the idea of guilt is prevalent, whereas it is somatic troubles and the idea of persecution that are in the foreground in non-western cultures, more particularly in Black Africa and the Maghreb. In the western world melancholy is not only a genuine standard model of depression but is also a cultural fact as witnessed by the numerous references in the literary and pictorial fields. The author asks us to ponder relations between the strength and frequency of guilt feelings on the one hand and the question of the debt and interiority of evil (sin) in the western christian tradition.

1. The equatorial X-ray diffraction pattern was recorded from a papillary muscle of a cross-circulated canine heart at different phases of the cardiac cycle. The intensity ratio of the 1, 0 and the 1, 1 reflexions (I1, o/I1,1) was 0-79 in the systolic phase and 1-19 in the diastolic phase. 2. Using the intensity ratio obtained, the approximate proportion of the myosin projections present in the vicinity of the thin filaments was calculated. This was 70-71% in the systolic phase and 51-52% in the diastolic phase of the total myosin projections. 3. The peak systolic tension was roughly proportional to the proportion of the projections present in the vicinity of the thin filaments during systole. 4. The projections which stayed in the vicinity of the thin filaments during diastole did not produce significant contractile force.

Liquid sheet disintegration at high pressure: An experimental approach  

NASA Astrophysics Data System (ADS)

The primary atomization was studied in a 300 ?m thickness water sheet, generated by a planar airblast atomizer. The research novelty consisted in increasing the airflow absolute pressure from atmospheric conditions to 6 bar. The experimental techniques employed included Oscillometry by Laser Intensity Reflexion (ORIL), Laser Doppler Velocimetry (LDV) and flow visualization by fast video camera. The atomization mechanisms, described in the literature at atmospheric environments, were observed at high pressure conditions, for a constant momentum flux ratio. Furthermore, a new atomization mechanism was observed at high values of this ratio. Finally, dimensionless relations have been proposed for the global oscillation frequency, minimum air oscillation velocity, break-up distance and transversal wavelength. To cite this article: V.G.

A multivariate analysis of morphometric characters of Heterorhabditis species (Nemata: Heterorhabditidae) and the role of morphometrics in the taxonomy of species of the genus.  

PubMed

A multivariate analysis on the morphometrics of 7 Heterorhabditis species was conducted to review the status of the traditional morphometric characterization methods for differentiating species of these nematodes. Results from this study showed consistency in the selection of morphometric characters for discriminating among males and infective juveniles of Heterorhabditis species. For the males, testis reflexion (TREF) and total length (LENGTH) were the variables that contributed most in the discrimination among the different species, and for the infective juveniles, tail length (TAILL) and total length (LENGTH) were the variables that contributed most. Therefore, we consider that these morphometric characters are useful and reliable, and that they should be used for the identification of Heterorhabditis species/isolates. PMID:8885892

Optical properties of large band gap ?-In 2S 3-3 xO 3 x compounds obtained by physical vapour deposition  

NASA Astrophysics Data System (ADS)

Thin films of large band gap ?-In 2S 3-3 xO 3 x compounds have been synthesised by annealing a multilayer structure of indium and sulphur sequentially deposited. X-ray diffraction measurements, electronic microprobe analysis and quantitative X-ray photoelectron analysis have been performed to characterise the samples. The absorption coefficient, determined from transmission and reflexion measurements, shows that the absorption threshold is blue shifted when oxygen is present in In 2S 3 and the gap increases about 30%. A theoretical modelisation of these compounds, using the known spinel structure Al 2MgO 4, is reported. The electronic structure has been calculated with the ab initio Tight Binding Linear Muffin Tin Orbitals method. We obtain an enhancement of the gap under lattice compression. Although this trend also appears in the absence of oxygen, the lattice compression is more favourable when oxygen is present.

Humidity sensing by carbon nanocones.  

PubMed

Carbon nano-structures, mainly nanotubes, have been explored in the past as sensing devices. In this report we have considered cones and discs (CNCs) subjected to acid treatment, dry oxidation and high temperature annealing, to study the modifications induced as they are used as sensing elements of varying relative humidity (RH). The relative humidity was varied in cycles of 30 min between 36% and 75%. Not strangely, the acid treated films displayed a much larger variation in resistance for the same difference in RH (16%). In the as-grown material, very small variations were detected among cycles under similar conditions. The changes induced in the sensors structures by the different preparation procedures were characterized by transmission electron microscopy (TEM) and Raman reflexion. These results were used to model their behaviour as RH sensors. PMID:24734591

Increased aortic stiffness and blood pressure in non-classic Pompe disease.  

PubMed

Vascular abnormalities and glycogen accumulation in vascular smooth muscle fibres have been described in Pompe disease. Using carotid-femoral pulse wave velocity (cfPWV), the gold standard methodology for determining aortic stiffness, we studied whether aortic stiffness is increased in patients with Pompe disease. Eighty-four adult Pompe patients and 179 age- and gender-matched volunteers participated in this cross-sectional case-controlled study. Intima media thickness and the distensibility of the right common carotid artery were measured using a Duplex scanner. Aortic augmentation index, central pulse pressure, aortic reflexion time and cfPWV were assessed using the SphygmoCor® system. CfPWV was higher in patients than in volunteers (8.8 versus 7.4 m/s, p?reflexion time (p?=?0.02), indirect indicators of arterial stiffness did not differ between patients and volunteers. Relative to volunteers (20%), more Pompe patients had a history of hypertension (36%, p?=?0.005), and the MAP was higher than in volunteers (100 versus 92 mmHg, p?

One of the most important problems in automatic image analysis is the discrimination of features by, a certain range of grey levels. To obtain as many as possible different grey levels sufficient contrast is achieved mainly by specific staining. Alternative and supplementary methods are some micrscopical methods, not routinely used. Interference microscopy, interference reflexion microscopy and microfluorimetry are discussed in detail. These optical procedures enhance the contrast of specimen specifically without the necessity for the application of specimen specifically without the necessity for the application of sophisticated staining methods. In interference contrast, tissues can be separately detected by grey level discrimination due to varying concentration of dry mass; this is shown for a cornifying part of fish skin (breeding tubercle of Rutilus rutilus L.). Furthermore, very small amounts of dry matter can be determined with high precision, as demonstrated for a single tissue culture cell (XTH-cell). Automatisation of image analysis provides a unique opportunity for routine application of interferometric measurements. The principles of the procedures are outlined. By interference reflexion microscopy cellular attachment areas to a glass surface are visualized, providing a powerful tool in cellular diagnosis based on grey level discrimination (darkest parts correspond to zones of closest contact to the substratum). A fast migrating lymphocyte and stationary endothelial cells have been chosen for demonstration. Various histochemical problems can be solved elegantly by fluorescence methods, e.g. mitochondria in living cells are specifically stained by a fluorochrome (DASPMI) and the distribution of fluorescence intensity can be followed within the mitochondrial population of a cell. Fluorescence was recorded from fotographic negatives taken with a fluorescence microscope. Additionally a short comment is given on the application of polarisation microscopy for feature detection.

Erosion and deformation processes associated with the transport of debris-flows - The example of the Matakaoa Debris Flow, offshore New Zealand  

NASA Astrophysics Data System (ADS)

East of the North Island of New Zealand, the Pacific plate subducts beneath the Australian plate along the Hikurangi active margin. There, the continental slope was repeatedly affected by mass-transport processes facilitated by high seismicity, tectonic deformation and high sedimentation rates resulting from the erosion of rapidly-uplifting ranges onland. Several major (>500 km3) mass-transport deposits have been identified in the fore-arc basin north-east of New Zealand. This study uses seismic reflexion profiles collected over the ~1250 km3 Matakaoa Debris Flow (MDF) deposits, dated 100-38 ky, to understand the processes of erosion and deformation occurring during transport of a major debris flow. We show why the identification of these processes is critical to analyze accurately the volume balance between failed and deposited material. The MDF deposits show the following typical zonation: 1/ Proximal deposits exhibit a semi-transparent, chaotic seismic facies, characteristic of a debrite. Seismic reflections of the underlying sedimentary series are conspicuously truncated, demonstrating that the debris flow eroded and incorporated ~ 150 m of sediments during transport. Along the eastern edge of the MDF deposits, rotated sediment slabs demonstrate that the sedimentary substrate was eroded laterally. 2/ Distal deposits exhibit a coherent seismic facies with flat-and-ramp structures interpreted as imbricate thrusts affecting the basin sediments. These thrust structures demonstrate that basin sediments were deformed in compression as a result from a "bulldozing" process triggered by the debris flow. Because the identified eroded and deformed basin sediments do not come from the MDF failure scar, erosive and deformational processes contribute to explain the great difference between the total volume of material transported during the MDF event (>1000 km3) and the limited volume of the failure scar (~100 km3). Geophysical tests of pre-stack depth migration were performed on multichannel seismic reflexion profiles in order to provide a fine analysis of P wave-velocity and give insight into the physical characteristics of some distinctive reflectors or units. The distal thrust structures of the MDF deposits propagated over a very continuous, sub-horizontal, high-amplitude reflector interpreted as a décollement. The geophysical analysis revealed a negative velocity anomaly along that décollement, suggesting that variations in porosity and/or fluid content may have favored the formation of a low-friction surface that enabled the propagation of thrust structures over long distances (>100 km).

First-principles investigation of the adsorption of the 2,5-pyridine di-carboxylic acid onto the Cu(011) surface  

NASA Astrophysics Data System (ADS)

First-principles calculations within the density functional theory (DFT) framework have been performed in order to investigate various conformations of the 2,5-pyridine di-carboxylic acid (PDCA) molecule adsorbed onto the Cu(011) surface. By means of DFT calculations the adsorption geometry, the bond formation and the electronic properties of PDCA molecule conformations on the Cu(011) surface have been studied. The most important structural property is the orientation of the COOH H atom which can point either toward the aromatic ring or toward the vacuum. This H atom position determines the possible reactions in which the adsorbed molecule can get involved and also has a significant impact on the value of the Cu-molecule system work function. Thus, we find that simply by changing the H atom orientation (from up to down) the Cu-molecule system work function can be varied with more than 2.5 eV. This is a significant result as a lot of effort is put nowadays in finding efficient ways for the in situ variation of the systems work function. Scanning tunneling microscopy (STM) images, reflexion absorption infrared vibrational spectra (RAIRS) as well as various thermodynamic properties (adsorption entropies, enthalpies) have also been investigated in order to get a better insight into the system studied and to provide support to possible experimental studies (STM or RAIRS experiments).

Comparison of refractive indices measured by m-lines and ellipsometry: application to polymer blend and ceramic thin films for gas sensors  

NASA Astrophysics Data System (ADS)

Two optical techniques, "m-lines" and spectroscopic ellipsometry, are compared for their suitability for obtaining the wavelength and temperature dispersion of the refractive index of thin film layers used in gas detector devices. Two types of materials often integrated into gas sensors are studied: a polymer organic-inorganic blend deposited by spin-coating typically used in near infra-red waveguides and the ceramic semiconductor SrTi1-xFexO3 (strontium titanate) doped with iron at concentrations x = 0.075 and 0.1 deposited by electron beam deposition. In this paper, we will compare the refractive index dispersion obtained by m-lines and ellipsometry, and comment on the differences between the measured parameters for the two materials. The chromatic dispersion will be represented by a three term Cauchy law. An intuitive method of verifying the measured indices using an integrating sphere and reflexion coefficient modelling techniques will also be demonstrated. Thermo-optic coefficients of the order of -1×10-4/K for both materials are reported, and very low chromatic dispersions are also measured thanks to the high sensitivity of the m-lines technique.

The birth of non-Euclidean geometry  

NASA Astrophysics Data System (ADS)

When reading Bolyai and Lobachevsky, one is struck by the similarities of their ways. The importance of the trigonometrical developments must be emphasised; they gave an analytical basis to the new Geometry, guaranteeing, to some extent, the consistence of the construction. This construction is not axiomatic; on the contrary, modern axiomatics came from a reflexion made necessary by the existence of the non-Euclidean Geometry. The Differential Geometry is independant of, but very close to, the non-Euclidean Geometry: they communicate through the spherical Geometry and the interpretation of the sum of the angles of a triangle in terms of an area. It is difficult to think that Gauss had not seen the relation between his researches on the theory of parallels and his intrinsic Geometry of surfaces. And we saw that Bolyai and Lobachevsky made explicit the ds 2 of their plane Geometry. Nevertheless, the time was not yet ripe, in the first half of the XIXth century, to interpret the non-Euclidean Geometry (of a synthetic origin) in terms of the Differential Geometry.

Distribution of mercury resistance among Staphylococcus aureus isolated from a hospital community  

PubMed Central

Results from clinical isolations confirmed that mercury resistance is common among antibiotic-resistant strains of Staphylococcus aureus present in a large general hospital although the correlation is not as high as that found by Moore (1960). The distribution of mercury-resistant strains among infections and carriers in surgical, medical, obstetric and geriatric patients and staff was studied. Attention was directed to the distribution among carriers since there are fewer extraneous factors operating among them, and a statistical analysis was made on the total number of mercury-resistant strains and the number of non-endemic strains; this latter figure was obtained by subtracting the dominant type 80/81, which is nearly always mercury-resistant and antibiotic-resistant, from the total. Analysis showed the geriatric patients to have a significantly higher proportion of mercury-resistant strains in both cases, and obstetric patients to have a significantly lower proportion when the total number of mercury-resistant strains was considered. Among the surgical, medical and staff categories, no significant difference in proportions could be found although a trend, in that order, of decreasing proportions of mercury-resistant strains present was noted. In those cases infected on admission with tetracycline-resistant strains, although mercury-resistant strains still predominate, mercury-sensitive strains make a sizeable contribution. This is a reflexion of their dominance in the non-hospital environment.

Surface blackening by laser texturing with high repetition rate femtosecond laser up to 1MHz  

NASA Astrophysics Data System (ADS)

The interaction between laser pulses and material surface can generate sub-wavelength surface structures named ripples. The used of ultrashort laser pulses avoid thermal effect in the lattice so the structures generated are well preserved and can be observed on various materials as metals, polymers or crystals. With increasing energy deposit, ripples grow to give cone-shape structures named spikes. All these structures are interesting to give special properties to the treated surface as coloration change, improvement of light absorption or modification of wettability properties. These structure generation process is well known for femtosecond Ti:Sa laser with a pulse duration below 100fs and repetition rates in the range of 10 kHz. However, to be relevant for industrial applications, the average power of the laser is a critical parameter. The emergence of new femtosecond Yb doped fiber lasers with pulse duration below 350fs permits an increase of the average power for a few years. We will present our latest results obtained for surface texturation on various metals such as stainless steel, titanium, aluminum and copper with these up to date laser source. We study the influence of the average power and of the repetition rate up to 1000 kHz on the surface structures generated on scanned areas. We obtain light reflexion below 7% on stainless steel and below 5% on titanium from 200nm to 2000nm. The characterizations of the results are done with SEM imaging, optical profilometry and with a spectrophotometer.

Integrated laboratory scale demonstration experiment of S-I cycle  

SciTech Connect

The Sulfur Iodine thermochemical cycle for the production of hydrogen is one of the promising approaches for use with next generation high temperature advanced nuclear reactors. Within the framework of an international collaboration (I-NERI project) between the American DOE and the French CEA, the development of a laboratory scale hydrogen production loop using the sulfur iodine cycle will be performed under prototypic conditions to demonstrate the key chemical processes, to check the materials and to provide the technical basis for evaluating the S-I cycle for nuclear hydrogen production (process efficiency and preliminary costs). The S-I cycle has been split into three sections. Each must complete stand alone tests prior to closed loop operation. CEA is responsible for the development, construction and operation of the Bunsen section where hydro-iodic acid and sulfuric acid are generated. After a general description of the loop and its objectives, a focus is made on the section provided by CEA, its design and the first tests performed in stand-alone mode. Reflexions on a preliminary scale up of major components for an industrial unit are also discussed. (authors)

Seismic assessment of geothermal potential: Concept and application Part 2: Application  

NASA Astrophysics Data System (ADS)

The exploration of renewable energies such as geothermal energy plays an important role in the reduction of greenhouse gas emissions, but its widespread economic use is limited by high uncertainties in the reservoir characterization and the resulting high investment risks. The aim of the MeProRisk project (with the project partners CAU Kiel, RWTH Aachen, FU-Berlin and Geophysica) is the improvement of geophysical methods for the exploration of the geothermal potential by setting up a concept which will be based on the combination of geophysical and hydraulic borehole measurements and thermal simulations (Part1: Concept, Szalaiova E., Iwanowski K., Rabbel W.). Since geothermal properties vary significantly in different subsurface conditions such as crystalline and sediments, different approaches in the fracture zones detection and the derivation of petrophysical boundary conditions for geothermal modeling must be defined. A comparative analysis of seismic data combined with borehole information was applied on the following two geothermally relevant locations: (1) Southern German crystalline: German continental deep drilling program (KTB), and (2) North German Basin sediments (provided by RWE-DEA). Available are 3D reflexion seismic datasets, numerous vertical seismic profiles and a dataset containing a big amount of various log data. The result is a 3D structure model, which will be used as input in the following modeling. This poster gives an overview of the current state of results and a comparison of the two datasets mentioned above.

[Coping of cybervictimization in adolescence - emotional and behavioral reactions to cyberbullying ].  

PubMed

The experience of cybervictimization is related to health, psychological, and behavioral problems among children and adolescents. Up to today research is scarce, how the persons affected by cybervictimization react and which determinants influence the choice for social, problem-focused, technical, or helpless coping behavior. The current online study with 428 adolescents considers age, sex, mean internet use, frequency of victimization, roles in cyberbullying, and emotional reactions to cybervictimization as potential determinants of the mentioned coping strategies. Based on the participant role approach, roles of cyberbullies, cybervictims, defenders or outsiders are frequently changing. Logistic regression analyses point out the important relevance of emotional reactions like anger or helplessness and the roles as cyberbully-victim or outsider. Further, younger participants reported cybervictimization more often, while the frequency of cybervictimization and sex did not and internet use only partially predict coping strategies. These findings corroborate the relevance of emotional reactions and the roles in the process of cyberbullying. As a starting point for prevention and intervention of cybervictimization, we suggest emotion regulation, teaching of technical coping behaviors as well as reflexion of roles in the context of cyberbullying. If feasible, different stakeholders should be engaged in this process: adolescents, parents, educational staff inside and outside of schools, experts from counseling and therapy as well as internet and mobile phone service providers.

How do silanes affect the lubricating properties of cationic double chain surfactant on silica surfaces?  

PubMed

The effect of an aminosilane on the lubricant properties of a C(18) double-chained cationic surfactant has been investigated in the context of glass fiber forming process. The surfactant adsorption was studied on silica by Fourier transform infrared (FT-IR) spectroscopy in the attenuated total reflexion (ATR) mode as a function of the aminosilane concentration in an organic water based formulation (sizing) used to coat the glass fibers during the process. A reciprocating ball-on-plate tribometer was used to compare friction properties of silica in contact with the aminosilane-surfactant mixture and in presence of each component of the sizing. Surface forces were measured between silica and an atomic force microscope (AFM) silicon nitride tip in the sizing and in the pure cationic surfactant solution. The aminosilane on its own has no lubricant property and reduces or even suppresses the cationic surfactant adsorption on silica. However, the silica-silica contact is lubricated even if the infrared spectroscopy does not detect any surfactant adsorption. The repeated contacts and shear due to the friction experiment itself induce accumulation, organization and compactness of surfactant bilayers. PMID:19059599

Algorithms for computer detection of symmetry elements in molecular systems.  

PubMed

Simple procedures for the location of proper and improper rotations and reflexion planes are presented. The search is performed with a molecule divided into subsets of symmetrically equivalent atoms (SEA) which are analyzed separately as if they were a single molecule. This approach is advantageous in many aspects. For instance, in those molecules that are symmetric rotors, the number of atoms and the inertia tensor of the SEA provide one straight way to find proper rotations of any order. The algorithms are invariant to the molecular orientation and their computational cost is low, because the main information required to find symmetry elements is interatomic distances and the principal moments of the SEA. For example, our Fortran implementation, running on a single processor, took only a few seconds to locate all 120 symmetry operations of the large and highly symmetrical fullerene C720, belonging to the Ih point group. Finally, we show how the interatomic distances matrix of a slightly unsymmetrical molecule is used to symmetrize its geometry. PMID:24403016

[Endoprosthetic replacement of hallux rigidus].  

PubMed

Replacement of the first metatarsophalangeal joint (MTP1) is still controversial when compared with MTP1 fusion in treating hallux rigidus and other disabling conditions of the MTP1 joint. Prospective studies concerning endoprosthetic replacement of the MTP1 joint are not available yet. Nevertheless, better understanding of biomechanics and tribology show favour towards total endoprosthesis. Some currently available models are described (Toefit-Plus, Roto-glide, ReFlexion, Bio-Action, Moje). Furthermore the authors report their results with 30 Toefit-Plus total endoprostheses. Five complications (16.6%) included two dislocations of total prostheses and three bone fissures. In 3 of 14 cases (21%) with a 3-year follow-up, revision surgery was necessary (subluxation, persistent pain, recurrence of hallux rigidus). Of 11 cases (63%) with a 4-year follow-up, 7 revealed secondary loss of range of motion. A more aggressive postoperative treatment with early weight bearing and regular push-off of the first ray is recommended. Based on our results, MTP1 replacement should be indicated restrictively (hallux rigidus, no experiments in cases of important first ray insufficiency). PMID:16010577

So some antenna designs are proposed for both lander and orbiter spacecrafts. Finally, a preliminary experiment budget is shown.

Growth of scandium doped GaN by MOVPE  

NASA Astrophysics Data System (ADS)

Scandium (Sc) doped GaN layers (GaN:Sc) were grown on SiN treated sapphire substrate by atmospheric pressure metal-organic vapor phase epitaxy (AP-MOVPE) using Tris(cyclopentadienyl)scandium (Cp3Sc) as a scandium precursor. Standard growth conditions of GaN were used with varying Cp3Sc flow rate up to 1000 sccm. The growth was in situ monitored by laser reflectometry. GaN coalescence process is significantly influenced by the presence of Cp3Sc. Sc incorporation in GaN is confirmed by secondary ion mass spectrometry (SIMS) measurements. Electron concentration and mobility variations versus Cp3Sc flow rate were studied by room temperature Hall effect measurements. All samples showed n type conductivity. High resolution X-ray diffraction (HRXRD) results showed a slight broadening of rocking curves around symmetric (00.2) reflexions for Sc doped GaN layers with increasing Cp3Sc flow rate. Room temperature photoluminescence (PL) showed a quenching of ultraviolet near band edge emission (UV) by increasing Sc doping level.

Reanimation of thumb opposition by the extensor pollicis longus. Report of sixteen cases.  

PubMed

Among some 65 techniques for restoring thumb opposition found in literature, the authors chose the extensor pollicis longus transfer (EPL) onto the abductor pollicis brevis (APB) through the interosseous membrane. This technique described by Duparc et al. in 1971 was codified by Bureau et al. in 1980 using a series of 9 cases. The sufficient force and length of this transfer, associated with its direct course by redirection through the interosseous membrane make it a docile, reliable motor unit as shown by the 16 cases studied. Performed on 11 median-ulnar palsies, 6 isolated median palsies and on one complete avulsion of lateral thenar muscles, only 16 of these 18 transfers could be satisfactorily followed and reviewed from 7 to 35 months later. In our series, 14 of the 16 cases have recovered functional opposition and are using it. After a review of the surgical technique the authors emphasize some practical aspects: dissection of the EPL which may be delicate, resection of the IM which should be adequate, and choice of the reflexion pulley and how to construct it. Results as well as sequelae linked to the choice of the EPL are then analysed. PMID:3963903

The Vitrification as Pathway for Long Life Organic Waste Treatment  

SciTech Connect

Worldwide, several vitrification processes have been developed and are industrially exploited for the vitrification of high level waste, attesting the efficiency of this technique for fission product treatment and glassy materials for nuclear waste containment is the conditioning that receives the best acceptance. However, these processes operate a very high technology and strangely, for less radioactive waste such as long live intermediate level waste, this technology did not break through even when their final disposal scenario are very close (except mainly thermal consideration). This reflexion gives example for anyone to appreciate how the vitrification of organics intermediate level waste can be an excellent solution and even a competitive technical-economic answer with limited industrial risks. By 'vitrification of organics', we mean in this paper the incineration/vitrification of mixed organic and mineral waste; this results in gasification of organic matter and vitrification of the oxidized mineral fraction of the waste. Such processes can accommodate any ratio of mineral/organic from pure burnable waste to pure mineral sludges. Many advantages come with the vitrification of organics: Treatment of the organic matter, gas release avoided, existing suitable glass composition families, and volume reduction. The technological characteristics that should show a vitrification process for organic waste according to our experience in this field is detailed and examples of treatment with chlorinated waste or old bituminous drums reprocessing are given.

Quasi-optical LHW launcher pre-design study for Tore-Supra, modelizations  

SciTech Connect

The {open_quote}Quasi-Optical Grill{close_quote} (QOG) has been proposed to increase the robustness and the simplicity of a Lower-Hybrid Waves antenna for reactor application [1]. To compare the performance of a QOG antenna with that of conventional scheme, an experiment was envisaged in TORE-SUPRA in cooperation with the ENEA. Encouraging modelling results [2] lead to conduct a pre-design study [3]. The main results of this study are presented in this paper. In particular, an analysis of the practical system has shown a limitation of the injected power due to either the appearance of large electric fields in the resonant structure, or to an increased reflexion linked with departures from ideal conditions. This analysis is based on the results of the diffraction code [2] developed by the ENEA complemented by a simple {open_quote}Fabry-Perot{close_quote} model. A further optimization is thus needed and is being undertaken to assess the future of the concept. {copyright} {ital 1996 American Institute of Physics.}

[Cockayne syndrome].  

PubMed

Cockayne syndrome is a rare autosomal recessive disease. This paper reports a case of Cockayne syndrome confirmed by gene analysis. The baby (male, 7 years old) was referred to Peking University Third Hospital with recurrent desquamation, pigmentation and growth and development failure for 6 years, and recurrent dental caries and tooth loss for 2 years. Physical examination showed very low body weight, body length and head circumference, yellow hair, a lot of fawn spots on the face, skin dry and less elastic, and subcutaneous lipopenia. He had an unusual appearance with sunken eyes, sharp nose, sharp mandible, big auricle and dental caries and tooth loss. Crura spasticity and ataxia with excessive tendon reflexion, and ankle movement limitation while bending back were observed. He had slured speech. The level of serum insulin like growth factor I was low, and the results of blood and urinary amino acid analysis suggested malnutrition. The results of blood growth hormone, thyroxin, parathyroxin, liver function, renal function, lipoprotein profile and blood glucose and electrolytes were all within normal limit. An electronic hearing examination showed moderate neural hearing loss. The sonogram of eyes revealed small eye axis and vitreous body opacity of right side. MRI of brain revealed bilateral calcification of basal ganglia and generalized cerebral and cerebellar atrophy, and brainstem and callus were also atrophic. Genetic analysis confirmed with CSA gene mutation. So the boy was definitely diagnosed with Cockayne syndrome. He was discharged because of no effective treatment. PMID:21342626

Crystal and molecular structure of (E)-5-(2-bromovinyl-2'-deoxyuridine).  

PubMed Central

(E)-5-(2-bromovinyl-2'-deoxyuridine) crystallizes in the space group P2(1) with a = 12.976(1), b = 4.800(1), c = 20.385(2) A, beta = 96.88(1) degrees, Z = (two molecules a and b in the asymmetric unit). The structure has been determined by the use of 2400 diffractometer reflexions and refined by least-squares to R of 0.053. Conformational features of both molecules a and b resemble those of thymidine. The ribofuranose rings assume the rare C(3')-exo form observed also in thymidine. Similarly, the torsion angles around the glycosidic bonds (mean = 40(1) and 56(1) degrees fall in the anti range. In each molecule the best plane of the 2-bromovinyl moiety is bent out of the least-squares plane of the pyrimidine base by 6 degrees, so that the positively charged C(8)-H(8) group can donate an intramolecular hydrogen bond to 0(4) atom. Eight strong and weak intermolecular hydrogen bridges are built up between the symmetry independent and related molecules forming a complicated three dimensional hydrogen bond network.

Solid organ transplant training objectives for residents.  

PubMed

With the aim of analyzing the current state of the educational objectives in the training of medical residents in solid organ transplantation (SOT), we conducted a review of the status of the official programs of the specialities involved in SOT, focusing particularly on lung transplantation. A survey of medical residents was also conducted to allow reflexion about the topic. We obtained 44 surveys from 4 University Hospitals with active programs in SOT, mainly from intensive care medicine and anesthesiology residents. We detected an important number of courses oriented to organ donation but very limited in terms of basic training in the management of the immediate postoperative period, principles of immunosuppression and updates on immunosuppressive therapy and complications (particularly rejection and infection). We also identified that these educational aspects should be directed not only to medical residents from specialities with a close retation to SOT, but also to all who may at some time have a relation to such patients. The use of information and communication techniques (ICTs), on-line courses and also simulations should be instruments to take into account in the biomedical training of medical residents. We conclude that we need a specific training program in complications of SOT, as well as fundamental principles in immunology and immunosuppressor pharmacology. PMID:22980670

Astrobiology : is humankind ready for the next revolution ?  

NASA Astrophysics Data System (ADS)

The discovery of a first exoplanet, in 1995, did not revolutionize but knocked astronomical sciences over. At the same time, by opening new prospects of research, in particular in the search of planets similar to the Earth and in a possible extraterrestrial life, this discovery, since then abundantly repeated, gave a new breath to the public interest for this scientific field. But is humanity ready to learn the existence from extraterrestrial forms of life or to remain, in spite of its efforts, in ignorance? The question of the plurality of the worlds is one of the oldest interrogations conveyed by the human cultures, as testified by the multiple answers which were brought to it. In the same way, the concept of life is itself an inexhaustible source of philosophical and religious reflexions, with many consequences in moral domains. It is today necessary to accompany the scientific development in the field of astrobiology by attaching the greatest importance to this intellectual patrimony. It constitutes even one of the first stages of an ethical responsibility in astrobiology, as important as that concerning planetary protection.

Deep imaging of the eastern Nankai trough through a dense OBS array  

NASA Astrophysics Data System (ADS)

A seismic experiment was conducted on the eastern Nankai trough in 2001 in the frame of a franco-japanese scientific cooperation program. Its aim is to provide well resolved images of the deep part of this active margin, where an important subduction earthquake is expected in a relatively near future. The plate contact constituting the seismogenic zone is more particularly targeted. The presence of possibly locking subducted asperities is expected to be a strong and likely structural factor that might control both the seismic rupture triggering and the coseismic slip distribution. In relation with this purpose, a hybrid seismic acquisition device was designed, featuring specificities of both classical refraction and multichannel reflexion experiments. This device consists in a single line of 100 OBSs with a constant spacing of 1 km that leads to a multifold, global offset seismic acquisition. This line is perpendicular to the trench, along the Eurasia/Philippine subduction system direction. We intend to apply new tomographic strategies on this kind of data with eventually a frequency domain 2~D full waveform inversion. To our knowledge, such a tool has never been applied in a crustal-scaled experiment; it should yield a dramatic improvement in the resolution of deep structures. Prior to this, a smooth tomographic model that explains traveltimes has to be designed, which is already achieved through a first arrival time linearized inversion. We will present the current state of this work and the tectonic implications of our results regarding the margin's evolution.

Crystal structure and phase transition of bis-aqua-sebacato magnesium Mg(C 10H 16O 4) 2(H 2O) 2  

NASA Astrophysics Data System (ADS)

The (bis aqua)(sebacato)magnesium Mg((? 2)-(? 1-? 1)-? 3-C 10H 16O 4)(H 2O) 2 was synthesized by hydrothermal route. The structure was solved ab initio using optimisation methods from powder X-ray diffraction (PXRD) laboratory data. The structure crystallises in the monoclinic space group P2 1/c with a = 17.336(1) Å, b = 7.456(1) Å, c = 9.573(1) Å, ? = 96.43 (1) °, V = 1229.61(9) Å 3, Dx = 1.407 g cm -3 and Z = 4. Rietveld refinement from 399 reflexions leads to a reliability factor Rbragg = 0.06. The structure consists of double sheets of Mg 2+ centred O-octahedra linked by H-bonds and bridged by sebacate anions along [100], building a 3D metal-organic framework 'MOF'. Heating at 100 °C provokes the condensation of the octahedra in an anhydrous compound Mg(C 10H 16O 4) .
