Non-Cavitational Tensile Creep in Lu-Doped Silicon Nitride

January 1, 2002
Author(s)
F Lofaj, Sheldon M. Wiederhorn, Gabrielle G. Long, B Hockey, P R. Jemian, L Browder, April Andreas
The tensile creep behavior of a Lu-based silicon nitride, SN 281, was studied in the temperature range 1400 C to 1550 C with test periods of up to 10 000 h. Strain rates were 3 to 5 orders of magnitude less than those for Yb-based grades of silicon nitride

Crystal Structure of Dephospho-Coenzyme A Kinase from Haemophilus Influenzae

November 1, 2001
Author(s)
G Obmolova, A Teplyakov, N Bonander, E Eisenstein, A J. Howard, G L. Gilliland
phospho-coenzyme A kinase catalyzes the final step in CoA biosynthesis, the phosphorylation of the 3'-hydroxyl group of ribose using ATP as a phosphate donor. The protein from Haemophilus influenzae was cloned and expressed, and its crystal structure

Can a Pressure Standard be Based on Capacitance Measurements?

March 1, 1998
Author(s)
Michael R. Moldover
We consider the feasibility of basing a pressure standard on measurements of the dielectric constant [epsilon] and the thermodynamic temperature T of helium near )[degrees]C. The pressure P of the helium would be calculated using the fundamental constants
