TL;DR: In this paper , the trends and status of industrial polychlorinated biphenyls (PCBs) in harbour porpoises were analysed using multiple linear regression models and toxicity thresholds for the onset of physiological (reproductive and immunological) endpoints were applied to all sex-maturity groups.
Journal ArticleDOI
An investigation into the effects of climate change on baleen whale distribution in the British Isles.

TL;DR: In this paper , the authors used linear regression models to compare the number of strandings over time between six regions of the British Isles and, whilst the results indicate no significant change in strandings in the most southerly region, there have been significant increases in more northern regions.
Book ChapterDOI
Aspects of General Relativity
TL;DR: While the effects of Einstein's general relativity are not observationally significant for the every day physics of terestial gravity, nor (in almost all cases) for the motion of planets about the sun, nor for stars within galaxies, and for galaxies about one another, the theory does give some observed (or observable) corrections to Newtonian theory in suitable circumstances as mentioned in this paper.
Journal ArticleDOI
Global General Relativity
TL;DR: Much of the theoretical work that has been carried out in General Relativity, particularly in the earlier years of the subject, has been concerned with finding explicit solutions of Einstein’s field equations, either in the vacuum case or, with suitable equations of state, when matter is present.
