New Computer Methods for Protein Crystallography, by Martin Zwick. Submitted to the Department of Biology on 30 August 1968 in partial fulfillment of the requirements for the degree of Doctor of Philosophy. The section, "MYOGLOBIN REFINEMENT," describes the fitting of an idealized polypeptide chain to a set of approximate backbone coordinates for the protein, sperm whale myoglobin. This procedure refines the structure by imposing upon it known bond distances and angles, and simultaneously derives a representation of the polypeptide conformation in terms of the values of the rotation angles about its single bonds. The overall rms and mean deviation between …

Grade Herd Recording, 1963-64, Maurice C. Cullity

Journal of the Department of Agriculture, Western Australia, Series 4

A review of Grade Herd Recording during the 1963-64 season.

THERE was a substantial increase in the number of cows which were recorded in 1963-64 compared with 1962-63 (23,520 and 22,635 respectively).

This season's figure represents 20.4 per cent, of all cows in the dairying districts.

The number of cows which completed lactation and therefore whose yields were included in the averages, rose from 17,258 to 19,011.

Grade Herd Recording : 1962-63, Maurice C. Cullity

Journal of the Department of Agriculture, Western Australia, Series 4

A poor season coupled with a 16 per cent, increase in the number of cows tested during 1962-63 led to a drop in the average yields of cows in the Grade Herd Recording Scheme.
