Scaling laws and thermodynamic analysis for vascular branching of microvessels

When blood flows through small vessels, the two-phase nature of blood as a suspension of red cells (erythrocytes) in plasma cannot be neglected, and with decreasing vessel size, a homogeneous continuum model become less adequate in describing blood flow. Following the Haynes’ marginal zone theory, and viewing the flow as the result of concentric laminae of fluid moving axially, the present work provides models for fluid flow in dichotomous branching composed by larger and smaller vessels, respectively. Expressions for the branching sizes of parent and daughter vessels, that provides easier flow access, are obtained by means of a constrained optimization approach using the Lagrange multipliers. This study shows that when blood behaves as a Newtonian fluid, Hess – Murray law that states that the daughters-to-parent diameter ratio must equal to 2^(-1/3) is valid. However, when the nature of blood as a suspension becomes important, the expression for optimum branching diameters of vessels is dependent on the separation phase lengths. It is also shown that the same effect occurs for the relative lengths of daughters and parent vessels. For smaller vessels (e. g., arterioles and capillaries), it is found that the daughters-to-parent diameter ratio may varies from 0,741 to 0,849, and the daughters-to-parent length ratio varies from 0,260 to 2,42. For larger vessels (e. g., arteries), the daughters-to-parent diameter ratio and the daughters-to-parent length ratio range from 0,458 to 0,819, and from 0,100 to 6,27, respectively. In this paper, it is also demonstrated that the entropy generated when blood behaves as a single phase fluid (i. e., continuum viscous fluid) is greater than the entropy generated when the nature of blood as a suspension becomes important. Another important finding is that the manifestation of the particulate nature of blood in small vessels reduces entropy generation due to fluid friction, thereby maintaining the flow through dichotomous branching vessels at a relatively lower cost.

Singling out individual inventors from patent data

An increasing number of studies in recent years have sought to identify individual inventors from patent data. A variety of heuristics have been proposed for using the names and other information disclosed in patent documents to establish who is who in patents. This paper contributes to this literature by describing a methodology for identifying inventors using patents applied to the European Patent Office, EPO hereafter. As in much of this literature, we basically follow a threestep procedure : 1- the parsing stage, aimed at reducing the noise in the inventor’s name and other fields of the patent; 2- the matching stage, where name matching algorithms are used to group similar names; and 3- the filtering stage, where additional information and various scoring schemes are used to filter out these similarlynamed inventors. The paper presents the results obtained by using the algorithms with the set of European inventors applying to the EPO over a long period of time.

Patenta't els gens

Tradicionalment, bona part dels científics que treballem en institucions públiques hem pensat que la manera més eficient per avançar en ciència és permetre el lliure accés al coneixement, una idea que aquestes mateixes institucions tendeixen a fer canviar estimulant-nos a patentar les nostres troballes -i si cal també ens ajuden a crear un spin-off per rendibilitzar-les econòmicament- [...].

Prestación laboral mediante las empresas de trabajo temporal según la legislación española

En los últimos años, es cada vez más frecuente que las necesidades puntuales de personal que tienen las empresas se cubran mediante trabajadores adscritos a una ETT. El elevado grado de aceptación de la contratación a través de esta vía no sólo deriva del hecho de ser un medio más flexible de contratación, sino tambien de los menores costes salariales que implican la contratación de trabajadores de empresas de trabajo temporal; siendo este el principio incentivo para su utilización. Así pues, el recurso de la contratación de los trabajadores de las empresas de trabajo temporal no sólo constituye un medio para atender a necesidades temporales de la empresa usuaria, sino que además se ha constituido en un medio de reducir los costes salariales. El aspecto más destacable de la relación que se crea , desde el punto de vista del trabajador, es que el empleador es la ETT, pese a que la prestación se realiza, fisicamente en la empresa usuaria. La contratación de trabajadores con la finalidad de cederlos con carácter temporal a otras empresas para hacer frente a necesidades conyunturales ha sido tradicionalmente prohibida por los ordenamientos laborales y considerada como tráfico ilegal de mano de obra, asimilándola a la actividad de intermediación en el mercado de trabajo con fines lucrativos, por estimar que ambas figuras podían atentar contra derechos fundamentales de los trabajadores. Sin embargo desde finales de la decada de los sesenta, los países centrales de la Unión Europea, teniendo ratificado, al igual que España, el convenio 96 de la OIT, han venido regulando la actividad de las empresas de trabajo temporal por entender que su actuación, cuando se desarrolla de forma debidamente controlada, lejos de perjudicar a los trabajadores por ellas contratados pueden canalizar un volumen muy importante de empleo cuya especialización e inmediatez en la respuesta, sobre todo en el sector de servicios, no puede ofrecerse a través de mecanismos tradicionales. Por otra parte, para los trabajadores constituye un mecanismo importante para acceder a la actividad laboral y familiarizarse con la vida de la empresa, posibilitando además una cierta diversificación profesional y formación polivalente, a la vez, que en determinados casos, facilita a ciertos colectivos un sistema de trabajo que les permiter compaginar la actividad laboral con otras ocupaciones no productivas o responsabilidades familiares. La puesta en marcha de la legislación reguladora del trabajo temporal ha cubierto un importante vacio que existia en la gestión de las empresas en el área de recursos humanos, fomentando el contrato de carácter fijo y regularizando situaciones de temporalidad.

An hydrochemical answer to a legislative demand involving health risk related to water quality

Effluents and surface waters around an area involved with the inking of tissues at Itatiba municipality, São Paulo State, Brazil, were chemically analyzed with the purpose of evaluating the influence on the water quality of the chemicals released, as well to provide answers to legislative requirements related to the São Paulo State Register 997 published on 31 May 1976.

Chronological Monte Carlo-based assessment of distribution system reliability

Regulatory authorities in many countries, in order to maintain an acceptable balance between appropriate customer service qualities and costs, are introducing a performance-based regulation. These regulations impose penalties, and in some cases rewards, which introduce a component of financial risk to an electric power utility due to the uncertainty associated with preserving a specific level of system reliability. In Brazil, for instance, one of the reliability indices receiving special attention by the utilities is the Maximum Continuous Interruption Duration per customer (MCID). This paper describes a chronological Monte Carlo simulation approach to evaluate probability distributions of reliability indices, including the MCID, and the corresponding penalties. In order to get the desired efficiency, modern computational techniques are used for modeling (UML -Unified Modeling Language) as well as for programming (Object- Oriented Programming). Case studies on a simple distribution network and on real Brazilian distribution systems are presented and discussed. © Copyright KTH 2006.

Qualidade da água utilizada para irrigação de hortaliças na região de Botucatu-SP

This work had as objective verifies the water quality used for irrigation by the vegetables producers of Botucatu-SP area. They were interviewed 27 producers that sell vegetables in the street markets of Botucatu. Among these producers, ten were selected, being one of each place. Three samples of water of each source were collected. The main standard to evaluate the obtained results were the CONAMA Resolution (National Environment Council) N° 357, March 17, 2005, that it establishes the standard for water classification. The Electric Conductivity was evaluated of agreement value suggested by CETESB and the color was verified according to OMS (Health World Organization), for potable water due to CONAMA Resolution not to stipulate a value for classification. For the public health, just the coliformes and nitrate are the preoccupying variables for they be related with the incidence of diseases, so, the analyzed waters, 40% of them (A, F, H and J producers) offer some risk for the health of Botucatu population, second established standard for CONAMA. We can to conclude that in a general way, those waters, are in conditions no alarming, because they don't present values very different from those established by the legislation.
