For the van der Waerden numbers, the original proof produced upper bounds that were not even primitiv...

They are keen to ramp up their efforts but losing 65 per cent of this year’s chicks has been a major blow, said Ana Isabel Fagundes of Portugal’s national ornithological society, SPEA. Conservationists have reinforced the nests that contain surviving birds to help protect them from the anticipated increased soil erosion as a result of...
