Lopez de Penalver's Reflexiones : an economic and mathematical approach  

Microsoft Academic Search

Juan Lopez de Penalver was an engineer and mathematician who trained in Spain, Central Europe and Paris. His Reflexiones sobre la variacion del precio del trigo (1812) contained three models of: (1) wages, wheat prices and mortality; (2) transport costs and location; and (3) constant relative prices, which were brought to an international readership in 1961.

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].  


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].  


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.  


?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.

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

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?].  


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.

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.

Mecanismos de plasticidad (funcional y dependiente de actividad) en el cerebro auditivo adulto y en desarrollo  

PubMed Central

Summary Introduction and development Sensory systems show a topographic representation of the sensory epithelium in the central nervous system. In the auditory system this representation originates tonotopic maps. For the last four decades these changes in tonotopic maps have been widely studied either after peripheral mechanical lesions or by exposing animals to an augmented acoustic environment. These sensory manipulations induce plastic reorganizations in the tonotopic map of the auditory cortex. By contrast, acoustic trauma does not seem to induce functional plasticity at subcortical nuclei. Mechanisms that generate these changes differ in their molecular basis and temporal course and we can distinguish two different mechanisms: those involving an active reorganization process, and those that show a simple reflection of the loss of peripheral afferences. Only the former involve a genuine process of plastic reorganization. Neuronal plasticity is critical for the normal development and function of the adult auditory system, as well as for the rehabilitation needed after the implantation of auditory prostheses. However, development of plasticity can also generate abnormal sensation like tinnitus. Recently, a new concept in neurobiology so-called ‘neuronal stability’ has emerged and its implications and conceptual basis could help to improve the treatments of hearing loss. Conclusion A combination of neuronal plasticity and stability is suggested as a powerful and promising future strategy in the design of new treatments of hearing loss.

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).

In the thought provoking, peer reviewed resource fifty misconceptions are identified. Some misconceptions are easier to identify because they are oversimplifications, overgeneralizations, or misidentifications.

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.

Objetivos Discutir críticamente la evidencia que sugiere que las alteraciones en los sistemas neuronales relacio-nados con las funciones ejecutivas, con la formación de preferencias y con la regulación de los estados emocionales sirven como base para el rasgo de personalidad impulsiva, así como su estado en subgrupos de pacientes con BN. Métodos Búsqueda selectiva de la literatura relevante. Resultados y conclusiones Esta discusión ilustra la complejidad de la relación entre la impulsividad y BN, donde la impulsividad actúa como un factor de vulnerabilidad que puede sensibilizar al sujeto con BN a estados emocionales negativos, durante los cuales modifica el impacto de estímulos internos y externos sobre el comportamiento y su regulación, favoreciendo así patrones de comportamiento maladaptativos e inflexibles.

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].  


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.

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.

[Renal replacement therapy by hemodialysis in Constantine (Algeria)].  


End-stage renal failure is considered a public heath problem that constitutes a heavy cost on communities worldwide. To be able to plan the treatment of this pathology, we must have reliable and updated information through health network which represents the best mean for planning and reflexion locally and nationwide. The aim of our study was to answer to this need through a local registry of renal replacement therapy and nephrology network that we have for the first time an inventory of this pathology in an Algerian town (Constantine), and in this article we present the first results concerning patients under chronic hemodialysis.

[Cancer of the breast: primary prevention of breast cancer by tamoxifen, eligibility criteria, alternatives to English proposals].  


During the spring of 1993, UKCCCR prevention trial group proposed to the french medical community to participate into the international breast cancer prevention trial by tamoxifen set up in Great Britain. In January 1994 this proposal was eventually judged unacceptable in France because of lack of reflexion on primary cancer prevention, medico-legal risks, tamoxifen use risks and the eligibility criteria. A randomized trial could be designed and carried out in France to evaluate the place of tamoxifen in breast cancer prevention in the following settings: post menopausal patient with atypical epithelial hyperplasia or lobular in situ carcinoma.

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


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.  


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.

[A notice for use for patients who benifit from an adrenaline pen. "Having an emergency kit is a good thing but knowing how to use it is better"].  


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].  


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.

An X-ray diffraction study of the cross-circulated canine heart.  

PubMed Central

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. Fernandez et al., C. R. Mecanique 337 (2009).

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


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.  


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.  


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?

[Selective contrast enhancement of microscopical specimen by optical procedures for automatized quantitative image analysis (author's transl)].  


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.

Ulnar Nerve Compression after Silastic Ulnar Head Replacement  

PubMed Central

A patient with silastic radiocarpal and ulnar head replacement arthroplasty presented six years after the operation with symptoms of ulnar neuropathy. Bone resorption of the distal ulna resulted in volar subluxation of the ulnar head implant which compressed the ulnar nerve at its entrance into Guyon's canal. Removal of the implant and decompression of the nerve resulted in recovery of ulnar nerve funcions. Compression neuropathy of the ulnar nerve should be considered a potential complication of the use of silastic ulnar head replacements. ImagesFigure 1Figure 2
