This book is about the use of fracture mechanics for the solution of practical problems; academic rigor is not at issue and dealt with only in as far as it improves insight and understanding; it often concerns secondary errors in engineering. Knowled

In this paper technical (im)possibilities of environment-friendly paints are discussed from a paint developer's point of view. Special attention is paid to acrylic emulsion paints for wood protection. Important and interesting examples are given base

The Saccharomyces cerevisiae CDC25 gene and closely homologous genes in other eukaryotes encode guanine nucleotide exchange factors for Ras proteins. We have determined the minimal region of the budding yeast CDC25 gene capable of activity in vivo. T

The design of fixed platform structures for deeper water and more hostile environments places increased emphasis on the consideration of long-life (> 10 6 cycles) corrosion-fatigue behavior of low- and medium-strength structural steels in seawater. A

An elastic-plastic fracture mechanics methodology for treating two-dimensional stable crack growth and instability problems is described. The paper draws on "generation-phase" analyses in which the experimentally observedapplied-load (or displacement
