Finite Element Analysis of Deformed Legs of Offshore Platform Structures

The element stiffness matrix of the equivalent beam or pipe element of the deformed leg of the platform is derived by the finite element method. The stresses and displacements of some damaged components are calculated, and the numeri-cal solutions agree well with those obtained by the fine mesh finite element method. Finally, as an application of this method, the stresses of some platform structures are calculated and analyzed.

Consumo de Cultura Digital y Piratería

[ES] En este trabajo se analiza la relevancia de las características individuales y del hogar en la toma de decisiones sobre la compra y la descarga ilegal de archivos musicales de Internet. Para este estudio, se utilizan los datos de la Encuesta de Hábitos y Prácticas Culturales (de 2010-2011), llevada a cabo por el Ministerio de Cultura en España. Esta cuestión se convierte en un tema interesante a tratar, ya que la revolución digital ha conseguido aumentar los medios disponibles para escuchar música, creando así un amplio abanico de oportunidades para los consumidores, tanto legales como ilegales. Comenzamos con un repaso a las consecuencias de la digitalización en el mercado de la música grabada, poniendo especial interés en los aspectos que se refieren a la demanda y motivamos el interés por estudiarla. Estimamos dos modelos de elección binaria en los que se analiza cuál es el efecto que tiene cada una de las variables sobre la compra y la descarga de música.

Annual Report of the Game and Fisheries Department for the period 1st July 1956 to 30th June, 1957

This report continues to cover the period of the financial year. Although, as before, for the sake of continuity and accuracy many of the statistics refer to the calendar year. The year has been notable in particular for the launching of extensive research projects on wild-life conservation problems, and much progress has already been made. This has been rendered possible by the greatly appreciated help and interest of the Fulbright Commission, who arranged for three experienced American wild-life scientists to work on these problems in Uganda. The latter have been working in conjunction with The Game and Fisheries Department's Biologist, as a team under the general Direction of the recently created Fauna Research Committee.

Realizar una visi??n hist??rica de la evoluci??n del concepto de deficiencia mental y de su marco asistencial y educativo desde el siglo XIX hasta el momento en que la escuela se interes?? por los deficientes, centr??ndose despu??s en el estudio de cuatro centros municipales de atenci??n al deficiente de Barcelona. El trato asistencial a los deficientes mentales, las escuelas municipales de Barcelona de ciegos, sordomudos y anormales y el Instituto Municipal de Deficientes de Vilajoana. Investigaci??n hist??rica sobre Educaci??n Especial basada en diferentes fuentes bibliogr??ficas especializadas as?? como en material epistolar y administrativo, a partir del cual realiza una primera parte de visi??n hist??rica del tema y una segunda parte centrada en el funcionamiento de cuatro escuelas de Barcelona que daban trato a deficientes antes de la Guerra Civil y durante ella. Material bibliogr??fico y documental. En un peque??o apartado de la investigaci??n utiliza diagramas de barras y circulares as?? como porcentajes para describir y distribuir a los alumnos que ingresaban en Vilajoana segun edad, sexo, tipo de trastorno, datos familiares, etc..

Modelling the secular evolution of migrating planet pairs

The subject of this paper is the secular behaviour of a pair of planets evolving under dissipative forces. In particular, we investigate the case when dissipative forces affect the planetary semimajor axes and the planets move inwards/outwards the central star, in a process known as planet migration. To perform this investigation, we introduce fundamental concepts of conservative and dissipative dynamics of the three-body problem. Based on these concepts, we develop a qualitative model of the secular evolution of the migrating planetary pair. Our approach is based on the analysis of the energy and the orbital angular momentum exchange between the two-planet system and an external medium; thus no specific kind of dissipative forces is invoked. We show that, under the assumption that dissipation is weak and slow, the evolutionary routes of the migrating planets are traced by the Mode I and Mode II stationary solutions of the conservative secular problem. The ultimate convergence and the evolution of the system along one of these secular modes of motion are determined uniquely by the condition that the dissipation rate is sufficiently smaller than the proper secular frequency of the system. We show that it is possible to reassemble the starting configurations and the migration history of the systems on the basis of their final states and consequently to constrain the parameters of the physical processes involved.

Ultrastructural features of the glandular region of the stomach of Piaractus mesopotamicus (Holmberg, 1887) with emphasis on the oxyntopeptic cell

The characteristics of the lining and glandular epithelial types of the wall of the stomach of pacu (Piaractus mesopotamicus Holmberg, 1887) were studied by transmission electron microscopy. Columnar mucous cells were observed in the lining epithelial surface and the glandular epithelium that invaginated in the lamina propria showed secretory cells or oxyntopeptic cells as called by some authors in the literature. The columnar epithelial cells are narrow and show a basal nucleus. They are rich in organelles and contain secretory granules of round or rectangular shape heterogeneously electron dense in the apical portion. In the basal region of the glands there are secretory cells. The luminal half of these cells has abundant tubules (tubulo-vesicular system) that communicate with the external medium. Deeper basally in the cytoplasm there are the nucleus, mitochondria of various shapes and other scattered organelles.
