Effect of heat input on the mechanical properties of welded joints in high strength steels

Experiments were carried out to determine the properties of the welded joints in 8mm thick high-strength steels produced by quenching and tempering and thermomechanical rolling with accelerated cooling (tensile strength 821–835 MPa). The dependence of the strength, elongation, hardness, impact energy and crack opening displacement on the heat input in the range 1.0–0.7 kJ mm21 was determined. The results show that the dependence of the strength of the welded joints decreases and that of the elongation increases. The heat input has only a slight effect on the impact energy and crack opening displacement in the heat-affected zone.

Changes in canola plant architecture and seed physiological quality in response to different sowing densities

The aim of this study was to evaluate changes in canola yield components and seed physiological quality in response to different sowing densities. The study was made in a greenhouse at the REIPESOL Company Technological Center, Madrid - Spain, with the commercial "Toccata" hybrid variety. The initial sowing density was 360,000 plants/ha and the plant population was later thinned down to include treatments of 250 and 180 thousand plants/ha. Harvested seeds were sent to the Seed Technology Center Laboratory (CATES) at the Madrid Polytechnic University (UPM) to evaluate changes in plant architecture and yield components, as well as the seed physiological quality of different plant parts. Results demonstrated that canola plants showed changes in morphology and yield components in response to different sowing densities. The population of 250,000 plants/ha showed the best seed yield demonstrating that maximum yield is directly related to a correct sowing density. The number of pods/plant was the most important component for increased seed yield/plant and seed yield/area. The spatial distribution of canola seeds in the plant and canola sowing density did not affect seed physiological quality.

Computational prediction of neural progenitor cell fates

Understanding how stem and progenitor cells choose between alternative cell fates is a major challenge in developmental biology. Efforts to tackle this problem have been hampered by the scarcity of markers that can be used to predict cell division outcomes. Here we present a computational method, based on algorithmic information theory, to analyze dynamic features of living cells over time. Using this method, we asked whether rat retinal progenitor cells (RPCs) display characteristic phenotypes before undergoing mitosis that could foretell their fate. We predicted whether RPCs will undergo a self-renewing or terminal division with 99% accuracy, or whether they will produce two photoreceptors or another combination of offspring with 87% accuracy. Our implementation can segment, track and generate predictions for 40 cells simultaneously on a standard computer at 5 min per frame. This method could be used to isolate cell populations with specific developmental potential, enabling previously impossible investigations.

The instrumentality of the portfolios in the teach-learning process: study with higher education Portuguese teachers

In a time when higher education come for deep changes and if intends an education more centered in the pupil, the teach-learning portfolios appears as a tool to use, because versatile and with innumerable potentialities. This article reveals the results gotten with higher education teachers, who we looked for to know if these appeal in use the teach-learning portfolios, in the curricular units that teach. We looked for, equally, to perceive of that forms these are used. This is an exploratory study, basically descriptive, that does not have pretensions to generalize for all the teaching population. We elaborated and we applied a questionnaire, with 290 teachers of higher education public, university and polytechnic. We verify that the percentage of the teachers that uses the portfolios in the teach- learning process is not very raised.

Perdurabilidad empresarial: concepto y significados

Los grandes aportes generados por las antiguas civilizaciones y los filósofos más destacados a lo largo del tiempo, permiten entender la procedencia de algunos términos de los que hoy en día se hace uso. Estas contribuciones comienzan a través de la concepción del término tiempo, desde la antigüedad hasta los tiempos modernos, las cuales conllevan a entender que el tiempo es aquel que define la durabilidad de las cosas. De acuerdo a esto, se propone un acercamiento sobre el origen del término perdurabilidad, el cual será la base de la presente investigación. Entender la procedencia del término y el uso que se le da a sí mismo, facilita la aplicación el ámbito empresarial; el cual, a partir de diferentes posturas de autores nacionales e internacionales y basados en los parámetros que ha establecido la Universidad del Rosario, se establece un marco teórico de apoyo para futuras investigaciones dedicadas a la perdurabilidad empresarial. Asimismo, se establecen o se plasman algunos principios o factores de éxito que ayudan a que una empresa logre traspasar fronteras en tiempo y en rentabilidad; es decir que no solo permanezca muchos años en el mercado, sino que además se mantenga en constante crecimiento y rentabilidad.

Technical education in England, Germany and France in the nineteenth century: a comparison

Este documento describe el desarrollo de la educación técnica en Inglaterra, Alemania y Francia durante el siglo XIX, contrastando sus similaridades y diferencias. También analiza el papel del Estado en la provisión de educación técnica en estos países. El artículo sugiere que el alto estándar científico y técnico en la enseñanza, contribuyó significativamente para que el país se convirtiera en una potencia económica. Por ejemplo, la creciente superioridad técnica de los alemanes sobre los británicos en actividades como producción química, tinturas, hierro y acero, ha sido atribuida al hecho de que los británicos persistieron en el uso de métodos empíricos que representaban una barrera para alcanzar mejoras y adaptación, mientras que los alemanes desarrollaron un sistema de educación universitario y politécnico con fuertes lazos industriales que le permitían convertirse en la potencia industrial mas grande de Europa al inicio del Siglo XX.

A Liderança: uma análise sobre o clima organizacional

No quotidiano de uma organização, facilmente se constatará a influência da liderança sobre o comportamento e o clima organizacional predominantes. Assim, o presente trabalho pretende evidenciar o grau e nível que tais inter-relações poderão assumir no seio das organizações. Neste universo, e tendo sobretudo em conta as exigências da gestão organizacional contemporânea, existem várias questões suscetíveis de ser levantadas. Bastarão as competências técnicas acumuladas e adquiridas para garantir a eficácia de um líder? Por outro lado, poderá este atingir os objetivos a que a organização se propõe se não estiver provido das devidas competências relacionais? Pretende-se igualmente determinar os fatores e condicionalismos que caraterizam o líder carismático, capaz de tornar o clima organizacional favorável ao aumento da produtividade dos trabalhadores, gerir equipas, estimular a motivação, fazer uso efetivo dos recursos e desenvolver a confiança nas pessoas. Além disso, focando a dimensão do comportamento organizacional pretende-se definir o contrato psicológico, a relação líder-membro e como esta influencia os comportamentos, a motivação e o trabalho. O estudo empírico incide sobre uma escola superior: O Instituto Politécnico da Guarda. Os resultados apontam para a existência de uma relação positiva indiciando que o contrato psicológico, existente entre colaboradores e liderança das unidades orgânicas da instituição em análise, assenta no envolvimento e satisfação favorável no que respeita às relações líder-membro.

La circulación del darwinismo en el Ecuador (1870-1874) (Debates)

En 1871, el jesuita alemán Theodor Wolf comenzó a difundir el darwinismo en el Ecuador a través de las clases de geología y paleontología que impartía en la Escuela Politécnica. Expuso una posición conciliadora del evolucionismo con el catolicismo, en el contexto de un Estado que promovía la cohesión y la identidad nacional a través de la moral católica y las ciencias como vehículo para el progreso. En este estudio se discuten algunos apuntes que atribuyeron estas enseñanzas como la razón por la cual Wolf se separó de la Politécnica y de la Orden Jesuita en 1874, en el marco de una controversia mayor, en la cual el darwinismo fue determinante.
