Few materials can withstand the onslaught of the sea for long and marine infrastructure needs regular maintenance. Reinforced plastics can provide a more durable replacement for the wood, steel and concrete materials traditionally used. George Marsh reports.

Four dimensional Einstein-(source free) Maxwell with a negative cosmological constant is obtained from eleven dimensional supergravity with internal space Mppr. Monopole solutions are explicitly given which are not a direct product of space-time with Mppr. The application of such solutions to the chiral fermion problem is discussed.
Based on the recently introduced concept of a statistical cluster point, a definition is given for the statistical core of a complex number sequence which is analogous to the Knopp core. The theorems proved here are statistical analogues of theorems about the Knopp core concerning its containment or invariance under a matrix transformation.
