Venus Atmosphere Profile from a Maximum Entropy Principle

The variational method with constraints recently developed by Verkley and Gerkema to describe maximum-entropy atmospheric profiles is generalized to ideal gases but with temperature-dependent specific heats. In so doing, an extended and non standard potential temperature is introduced that is well suited for tackling the problem under consideration. This new formalism is successfully applied to the atmosphere of Venus. Three well defined regions emerge in this atmosphere up to a height of $100 km$ from the surface: the lowest one up to about $35 km$ is adiabatic, a transition layer located at the height of the cloud deck and finally a third region which is practically isothermal.Comment: 6 pages, 3 figure

A highly detailed land-use vector map for Madrid region based on photo-interpretation

Land Use – Land Cover (LULC) maps have developed remarkably since the global community became aware of the importance of knowing where LULC change is taking place on the Earth's surface. The rapid evolution of geographic information data handling and the automation of satellite image interpretation through remote sensing techniques and algorithms is providing increasingly abundant and up-to-date information on LULC. In addition, at large detail scales, it is important to link LULC maps to available statistical information, such as census information and business activities, which allow land parcels to be more accurately classified. Though automated classification methods can produce useful maps at smaller detail scales, it is not usually possible to accurately map urban areas at large scales without considerable investment of human resources. The development of large-scale information for urban areas is very important, especially in urban areas with accelerated rates of urban change which may jeopardize natural resources and citizens’ quality of life. In this paper, the creation of a set of large detail scale LULC maps and accompanying geodatabase for one such dynamic urban change region, the Madrid Autonomous Community (AC), Spain, is discussed

Urban Sprawl in the Mediterranean Urban Regions in Europe and the Crisis Effect on the Urban Land Development: Madrid as Study Case

The middle of 2007 saw the beginning of a worldwide financial crisis that led to a sharp reduction in investment based on construction and urban development. This new situation is generating a new process, characterised by a slowdown that has almost reached a standstill when compared with the frenzied development of previous decades. In order to analyse these processes, this study examines urban land use changes and the urban growth rate and spatial dynamics of the metropolitan region of Madrid. The analysis has been carried out on a large scale between two periods (2000?2006 and 2006?2009) using a regional land use geodatabase. The results show the changes in the urban land use dynamics that took place over these two periods that could characterise the cities of Mediterranean Europe, where contrarily to the general pattern in Europe built-up areas are combining scattered built-up areas with new aggregated compact developments

Introduccion de acciones de mejoras basado en datos obtenidos de analisis de lubricante de equipos de mineria subterranea

59 p.El presente trabajo es realizado en la empresa Zublin Gmbh obra Candelaria norte lugar en donde me desempeño en el área mantenimiento de maquinaria pesada de minería subterránea y mis estudio de ingeniería de ejecución en mecánica y experiencia en el rubro me permitió tomar una serie datos, de resultados de pruebas realizadas a los lubricantes que se encontraban dispersos, para establecer acciones de mejoras sobre los motores Detroit serie 50 que me permitieron mejorar la disponibilidad de los equipos en un 18%, disminuir la cantidad de horas de falla a un 5% y disminuir las emisiones de gases de escape evacuados hacia el ambiente

Avaliação da difusibilidade de campos acusticos reverberantes usando a tecnica de dois microfones

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro TecnologicoEste trabalho tem como objetivo apresentar um estudo da difusibilidade de campos acústicos, através da estimativa da função coerência entre a pressão sonora e a velocidade de partícula usando a técnica de dois microfones próximos e um analisado FFT de dois canais. Analisaram-se e mediram-se duas câmaras reverberantes usando este método, e compararam-se os resultados com os obtidos por métodos normalizados. Desta forma, qualifica-se a difusibilidade do campo acústico com precisão e boa resolução. Foi feito também, um estudo de erros sistemáticos das estimativas da função de coerência e as soluções usadas para minimizá-los

Is Senescence Important in Hepatic Diseases?

Aging is a condition in which a person gradually loses the ability to maintain homeostasis, due to structural alteration or dysfunction. Aging changes biological processes in many organs and tissues. The loss of regenerative capacity is the most dramatic age-associated alteration in the liver. Cellular damage, if not repaired, leads to apoptosis or senescence. The presence of permanent cell cycle arrest, the acquisition of major morphological change, and expression of senescence-associated β-galactosidase (SA-β-gal) are the characteristics of cellular senescence (CS). Interestingly, CS plays a crucial role in aging of both individual organs and the entire organism; consequently, senescent cells accumulate in organs and decline in organ function. Senescent cells have considerable influence on their microenvironment and exert both beneficial and detrimental effects through secretory associated senescent phenotype (SASP) factors. CS has attracted considerable recent interest with recognition of pathways linking aging, malignancy, and insulin resistance and the current focus on therapeutic interventions to extend healthspan. There are major implications for hepatology in the field of fibrosis and cancer, where cellular senescence of hepatocytes, cholangiocytes, stellate cells, and immune cells has been implicated in chronic liver disease progression

El análisis del coste del ciclo de vida y la evaluación de la intervención sostenible en el patrimonio arquitectónico

“Conseguir un equilibrio óptimo entre el coste y los resultados y producir el mínimo impacto posible en el patrimonio arquitectónico, utilizando los fondos disponibles de una manera racional” (ICOMOS, Principios, 1.6) constituyen objetivos clave en los procesos de intervención en el patrimonio arquitectónico para “lograr la eficiencia y efectividad de las propuestas adoptadas, teniendo en cuenta la viabilidad económica y los aspectos medioambientales y sociales de la sostenibilidad” (Nueva Carta de Atenas 2003). Este trabajo se propone revisar el coste del ciclo de vida, una herramienta prevista para el análisis de la viabilidad sostenible de todo tipo de actividades, como un enfoque para la evaluación de proyectos, estrategias y políticas, tanto públicas como privadas, de intervención en el patrimonio arquitectónico. Se propone así introducir el método en los procesos de toma de decisiones incorporando conceptos tales como la durabilidad, obsolescencia y ciclos de vida diferenciales de estructuras y elementos preexistentes y de materiales y sistemas tecnológicos innovadores, así como el impacto de las externalidades positivas en la reutilización de los espacios históricos a lo largo de su ciclo de vida
