Seasonal pattern of secondary growth in stems of northern white spruce (Picea glauca (Moench) Voss)

Creator:

Gregory, Robert A.

Abstract:

Cambial activity in white spruce stems in Alaska was observed from April, 1964 to September, 1965 in over 300 samples taken from 50- to 60-year-old natural stands. Mitotic index was used as a measure of the rate of periclinal division of fusiform cells in the cambial zone. Anticlinal divisions are...

Some aspects of an oxidative tryptophan decarboxylating enzyme in Pisum sativum

Creator:

Taylor, Frank Farnham

Abstract:

Three types of experiments were designed to further characterize the tryptophan decarboxylating enzyme of Reed and Crecelius (1967). 1) Light inhibition studies were made with etiolated pea seedlings to determine the in vitro response of the tryptophan decarboxylating enzyme. Assays of indoleacetic acid oxidase (IAA oxidase) and guaiacol-active pea seedling...

Masters Thesis
An interactive man-hybrid computer parameter search algorithm

Creator:

Morgan, Max J.

Abstract:

An interactive man-hybrid computer algorithm is presented for searching a set of dynamic system parameters which effect a compromise between performance characteristics and give satisfactory system sensitivity without any analytical calculations or a priori indices of performance. The parameter search is conducted in a real time design situation in which...
