Conformation dependence of the SH and CS stretch frequencies of the cysteine residue
(Wiley Subscription Services, Inc., A Wiley Company, 1992-11)
In order to relate the observed SH and CS stretch frequencies of the cysteine residue in proteins more closely to its conformation, we have done normal mode calculations on a model for this structure, viz., (CCONH)(CNHCO)CHCH ...
Nonlinear control of a batch polymerization reactor: An experimental study
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1992-09)
This work studies the experimental application of the globally linearizing control (GLC) method to a batch polymerization reactor. The nonlinear controller is implemented on a microcomputer to start up the reactor and then ...
Discrete-time nonlinear controller synthesis by input/output linearization
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1992-12)
This work concerns the synthesis of discrete-time nonlinear controllers for nonlinear processes that make the closed-loop system linear in an input/output sense. The synthesis of state feedback controllers is studied first, ...
Molybdenum/cobalt/sulfur clusters: Models and precursors for hydrodesulfurization (HDS) catalysts
(John Wiley & Sons Ltd., 1992-09)
Sulfido clusters which incorporate molybdenum and a late transition metal, e.g. iron, cobalt or nickel, are readily prepared by the reactions of Cp 2 Mo 2 S 4 , Cp 2 Mo 2 S 2 (SR) 2 or Cp 2 Mo 2 (CO) 2 (SR) 2 with Fe 2 ...
DNA-binding and non-DNA-binding forms of the transformed glucocorticoid receptor
(Elsevier, 1992-03)
In this work we have probed the mechanism responsible for two non-DNA-binding states of the mouse glucocorticoid receptor. In the first case, transformed receptors were treated with hydrogen peroxide. It is known that ...
Interactions of von Willebrand factor on mica studied by atomic force microscopy
(Elsevier, 1992-01)
Three-dimensional molecular level images of uncoated human von Willebrand factor (vWF), a plasma glycoprotein, have been obtained using atomic force microscopy (AFM). However, the structural detail obtained by AFM was found ...
Research on dust explosions at the University of Michigan
(Elsevier, 1992-08)
Dust explosion research carried out at the University of Michigan during the last two decades has been summarized. Significant results are presented on the smoldering combustion of dust heaps, turbulent combustion of ...
Synthesis of high-affinity, hydrophobic monosaccharide derivatives and study of their interaction with concanavalin A, the pea, the lentil, and fava bean lectins
(Elsevier, 1992-12)
Concanavalin A (Con A) and agglutinins from the pea (PSA), lentil (LCH), and fava bean (VFA) constitute a group of -mannose/-glucose binding legume lectins. In addition to their sugar binding specificity, these lectins ...
Treatment of redundancies among internal coordinates in optimizing molecular mechanics force constants
(John Wiley & Sons, Inc., 1992-11)
The use of redundant coordinate bases in the construction of molecular mechanics force fields is discussed. It is shown that the intrinsic indeterminacy in a force field in redundant coordinates in general stems from the ...
Some P---H bond substitution derivatives and fluxionality of Cp2Mo2([mu]-H)([mu]-PHPh)(CO)4
(Elsevier, 1992-11-10)
Reaction of PH2Ph with Cp2Mo2(CO)4 (Mo[triple bond]Mo) results in sequential formation of Cp2Mo2(CO)4(PH2Ph)2 and fluxional Cp2Mo2([mu]-H)([mu]-PHPh)(CO)4. Proton abstraction from Cp2Mo2([mu]-H)([mu]-PHPh)(CO)4 affords ...
