27 p, 3.8 MB Response of a comprehensive climate model to a broad range of external forcings : relevance for deep ocean ventilation and the development of late Cenozoic ice ages / Galbraith, Eric (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; de Lavergne, C. (University of New South Wales. School of Mathematics and Statistics)
Over the past few million years, the Earth descended from the relatively warm and stable climate of the Pliocene into the increasingly dramatic ice age cycles of the Pleistocene. The influences of orbital forcing and atmospheric CO on land-based ice sheets have long been considered as the key drivers of the ice ages, but less attention has been paid to their direct influences on the circulation of the deep ocean.

Departament de Medicina)
The interest in measuring physiological parameters (especially arterial blood gases) has grown progressively in parallel to the development of new technologies. Physiological parameters were first measured invasively and at discrete time points; however, it was clearly desirable to measure them continuously and non-invasively. [...]

Ocean acidification is considered a major threat to marine ecosystems and may particularly affect calcifying organisms such as corals, foraminifera and coccolithophores. Here we investigate the impact of elevated pCO2 and lowered pH on growth and calcification in the common calcareous dinoflagellate Thoracosphaera heimii. [...]

(Swedish University of Agricultural Sciences. Department of Forest Ecology and Management)
Ectomycorrhizal symbiosis is omnipresent in boreal forests, where it is assumed to benefit plant growth. However, experiments show inconsistent benefits for plants and volatility of individual partnerships, which calls for a re-evaluation of the presumed role of this symbiosis. [...]

Este trabajo es un estudio preliminar para el desarrollo de un metodo de extraccion de pesticidas directamente de las muestras de cera mediante extraccion con fluido supercritico. La novedad del estudio consiste en la extraccion directa de los pesticidas de la cera de lana cruda sin ninguna limpieza previa, cuando muchos autores han considerado casi imposible la extraccion directa.
The work presented is a preliminary study for the development of a method for the extraction of pesticides from wax samples by means of superficial fluid extraction. The novelty of the study is the direct extraction of the pesticides from raw wool wax without any cleanup, as direct extraction has been considered almost impossible by many authors.
