Overfishing and other human pressures are severely harming many marine protected areas around the world, study finds
ecological destruction edge effect marine conservation areas MPA
2021/8/11
A new study points to a strong 'edge effect' in marine protected areas (MPAs), sharply reducing by 60 percent the fish population living up to 1 - 1.5 km within the MPA. This significantly diminishes ...

The effect of wheat gluten or extracted soybean meal (300 g of crude protein/head/day) on milk yield, composition and its physical properties was analysed in 53 cows of Polish Holstein-Friesian breed ...
Surrogate Parenthood: Protected and Informative Graphs
Surrogate Parenthood Protected Informative Graphs
2011/9/14
Many applications, including provenance and some analyses of social networks, require path-based queries over graphstructured data. When these graphs contain sensitive information, paths may be broken...
Group-Theoretical Classification of BPS and Possibly Protected States in D=4 Conformal Supersymmetry
Group-Theoretical Classification of BPS Possibly Protected States D=4 Conformal Supersymmetry
2011/3/3
We use earlier results on the classification of the positive energy unitary irreducible representations of the N-extended D=4 conformal superalgebras su(2,2/N). These results are applied to the reduct...
