The static and dynamic electric quadrupole moments of even-even
and odd-A nuclei with 150<A<190 have been compiled and analyzed in a
systematic way, in order to extract the best set of intrinsic
quadrupole moments Q₀. The intrinsic quadrupole moments of the odd-A
nuclei have been used together with a compilation...
In this study, pulsed NMR is used to probe the hyperfine
interactions in liquid Se₀₅Te₀₅ doped with 3% Ga over the
temperature range from 500 °C to 900 °C. Both resonance shifts and
relaxation times are determined for ⁷⁷Se, ⁷¹Ga and ⁶⁹Ga.
NMR on both Ga-isotopes allows one to measure...
An information processing model of the problem-solving
performance of mechanical designers is presented for four design
tasks: conceptual assembly design, layout component design, detail
component design, and catalog selection. These tasks are organized
into six kinds of segments called episodes, which describe the goal
structure of the designer while performing...
To understand the influence of selective harvesting on
the adaptive capacity of fish populations in changing
environments, a computer simulation model was developed. In
the model, hypothetical populations were composed of five
different life histories, which were genetically determined.
Each life history type had its own rate of survival and...
The possible effect of oxidation [processing with or without sulfur dioxide
(±S0₂)] and of pre-ultrafiltration treatment of juices with enzymes and fining
agents on flux, and on juice color, composition and stability was investigated. White
Riesling juice was ultrafiltered with a Romicon system operated with a nominal
molecular weight cut-off...
