Carboniferous Forest at Oldham

Reform reform: an essay by John Oldham.

The NHS in England has undergone structural reform more times than I have changed my mobile phone. The driver is almost always political, with the government, of whichever party, reacting to public frustrations with the health and care system. These frustrations express themselves both publicly in the media and more privately in the constituency surgeries of members of parliament. Concerns ofte...

Stochastic Forest Modelling at the Forest Level

If taken into account, climate change will, according to current knowledge, have considerable consequences for forest management. However, there is considerable uncertainty regarding what future climate trajectory will follow. The possibilities to analyze uncertainties like this in terms of optimal forest management problems are limited. This is due to, e.g., lack of appropriate methodology, es...

Numerical Simulation and Experimental Examination of an Oldham Coupling

In scroll compressors, Oldham couplings (OCs) have typical been formed of aluminum alloy and have often broken issues due to the high loads which are transmitted from the orbiting scroll. This problem was especially pronounced during flooded start or slug conditions. In this paper, five pcs mass production OCs (standard OC), which are broken during a special slug test are investigated by classi...

Tomographic Reconstruction of Neopterous Carboniferous Insect Nymphs

Two new polyneopteran insect nymphs from the Montceau-les-Mines Lagerstätte of France are presented. Both are preserved in three dimensions, and are imaged with the aid of X-ray micro-tomography, allowing their morphology to be recovered in unprecedented detail. One-Anebos phrixos gen. et sp. nov.-is of uncertain affinities, and preserves portions of the antennae and eyes, coupled with a heavil...
