Nest Usurping Occurrence Of The Piratic Flycatcher (Legatus Leucophaius) In Southwestern Costa Rica

El Mosquerito Pirata (Legatus leucophaius) roba nidos colgantes o en forma de domo hechos principalmente por tiranidos o icteridos, sin embargo la frecuencia con la cual este mosquero se roba los nidos de otras especies es poco conocido. El Mosquerito Pirata robó nidos terminados de los Mosqueros Social (Myiozetetes similis) y Cabezigris (M. granadensis), construidos en sitios abiertos entre 5 – 9 m de alto. Nidos de otras especies con características similares pero menos abundantes o defendidos agresivamente, no fueron robados por el Mosquerito Piratas. A lo largo de su distribución reproductiva, son registrados usurpaciones de nidos por el Mosquerito Pirata en especies de al menos de cinco familias de aves.The Piratic Flycatcher (Legatus leucophaius) usurps pensile or domed nests mainly of other flycatchers (Tyrannidae) and icterids (Icteridae), but the frequency of nest parasitism is little known. In our study in south-west Costa Rica, the Piratic Flycatcher took over the finished domed nests of the Social (Myiozetetes similis) and the Gray-capped Flycatcher (M. granadensis), constructed in open sites between 5–9 m height. Nests of other species with similar characteristics, but less abundant or defended more aggressively, were not parasitized by the Piratic Flycatcher. Throughout its breeding range, nest usurpations by the Pyratic Flycatcher have been recorded for species belonging to at least five bird families.UCR::Vicerrectoría de Docencia::Ciencias Básicas::Facultad de Ciencias::Escuela de Biologí

Comprehensive lung injury pathology induced by mTOR inhibitors

Molecular Targets in Oncology[Abstract] Interstitial lung disease is a rare side effect of temsirolimus treatment in renal cancer patients. Pulmonary fibrosis is characterised by the accumulation of extracellular matrix collagen, fibroblast proliferation and migration, and loss of alveolar gas exchange units. Previous studies of pulmonary fibrosis have mainly focused on the fibro-proliferative process in the lungs. However, the molecular mechanism by which sirolimus promotes lung fibrosis remains elusive. Here, we propose an overall cascade hypothesis of interstitial lung diseases that represents a common, partly underlying synergism among them as well as the lung pathogenesis side effects of mammalian target of rapamycin inhibitors

Fluid solid interactions – a novelty in industrial applications

The article deals with a current state-of-art of fluid solid interaction (FSI) – the new branch of continuum physics. Fluid-solid interaction is a new quality of modeling physical processes of continuum mechanics, it can be described as the interaction of various (so far treated separately from the point of view of mathematical modeling) physical phenomena occurring in continuous media systems. The most correct is the simultaneous application of the laws of the given physical disciplines, which implies that fluid solid interaction is a subset of multi-physical applications where the interactions between these subsets are exchanged on the surface in interconnected systems. Our purpose is to extend the fluid solid interaction aplications into new phenomena what follow from the industrial needs and inovative thechnologies. Selecting the various approaches, we prefer the arbitraty lagrangean-eulerian description within the bulk of fluid/solid domain and a new sort of advanced boundary condition on a surface of common contact
