this paper presents an auto redundant technique for analysis of grid with curved members.this technique is based on the force method, but in the technique choice of the redundant iscompletely eliminated. the analysis technique is found very effective, accurate andprogrammable. a comprehensive c++ program has been developed to compute internalforces at the end of each member of the grid for diff...

This Chapter introduces the major themes of this book. In many ways, Mercury is an extreme planet, and thus it provides a unique benchmark for testing our theories about the origin and evolution of other (particularly terrestrial) planets. Emphasis is given to synthesizing and critiqueing the book's chapters on the planet's origin, its metal-rich composition, its thermal and geophysical evoluti...

foreign policy cooperation and coordination among the european community member states and presenting europe with a single voice, has long been an important challenge within the european community/european union, especially since early 1970s. in the early 1990s, following the collapse of the ussr and the end of the cold war, there was a general speculation in europe that the ec may be able to p...

The heat capacity of a natural monticellite (Ca,.,Mg.,,Fe.~Mn.o,Sio.9903.99) measured between 9.6 and 343 K using intermittent-heating, adiabatic calorimetry yields C$298) and S&s of 123.64 f 0.18 and 109.44 +0.16 J mol-’ K-’ respectively. Extrapolation ofthis entropy value to end-member monticellite results in an S$, = 108.1 + 0.2 J. mol-’ K-‘. High-temperature heat-capacity data were measured...

Hairpin structures can inhibit DNA replication and are intermediates in certain recombination reactions. We have shown that the purified SbcCD protein of Escherichia coli cleaves a DNA hairpin. This cleavage does not require the presence of a free (3' or 5') DNA end and generates products with 3'-hydroxyl and 5'-phosphate termini. Electron microscopy of SbcCD has revealed the "head-rod-tail" st...
