Cryptic diversity in Indo-Pacific coral-reef fishes revealed by DNA-barcoding provides new support to the centre-of-overlap hypothesis.

Diversity in coral reef fishes is not evenly distributed and tends to accumulate in the Indo-Malay-Philippines Archipelago (IMPA).The comprehension of the mechanisms that initiated this pattern is in its infancy despite its importance for the conservation of coral reefs.Considering the IMPA either as an area of overlap or a cradle of marine biodive

MATHEMATICAL MODEL OF THE STRESS-STRAIN STATE OF A BEAM WITH A VARIABLE SECTION WITH AN EFFECT OF "BOUNDARY LAYER"

The essence of this mathematical model consist in construction of the basic stress-strain state which is based on a new hypothesis of a vertical element and an additional stress-strain state of the regional flat deformation arising of close rigidly jammed edge.It gives the chance more exactly to estimate the strength of aircraft structures near to
