Wheat quality surveys in Western Australia
SINCE 1956 a number of collaborative wheat quality surveys have been carried out in Western Australia by Co-operative Bulk Handling Co. Ltd. and the Department of Agriculture.
The work was undertaken to provide facts which may be used to determine the possible advantages to this State\u27s wheat industry of alterations in the receival and marketing arrangements.
The various surveys are described in this article
Grain moisture problems on the south coast
In most West Australian grain growing districts high temperatures and dry weather at grain maturation are ideal for harvesting and enable delivery of grain with acceptable moisture levels. Grain from W.A. is known in world markets as a good quality dry product which is unlikely to deteriorate in storage. However, growers in coastal areas and particularly those south of Narrogin sometimes have trouble harvesting grain below the receival limit of 12 per cent moisture
Insignia lowers wheat quality
Farmers in Western Australia have been advised not to plant Insignia wheat because it has poor grain quality. Many farmers want to know why Insignia is considered poor quality and what harm it could do. This article answers these questions and suggests alternative, better quality wheats for all present situations
Biscuit wheat in W.A
Following small scale trials in the production and evaluation of Gluclub wheat in 1970 and 1971, farmers have been asked to produce 20,000 tons of this variety for the 1972/73 season.
The background of this attempt to establish a class of soft or biscuit wheat in world markets is described in this article
Phase separation and collapse in Bose-Fermi mixtures with a Feshbach resonance
We consider a mixture of single-component bosonic and fermionic atoms with an
interspecies interaction that is varied using a Feshbach resonance. By
performing a mean-field analysis of a two-channel model, which describes both
narrow and broad Feshbach resonances, we find an unexpectedly rich phase
diagram at zero temperature: Bose-condensed and non-Bose-condensed phases form
a variety of phase-separated states that are accompanied by both critical and
tricritical points. We discuss the implications of our results for the
experimentally observed collapse of Bose-Fermi mixtures on the attractive side
of the Feshbach resonance, and we make predictions for future experiments on
Bose-Fermi mixtures close to a Feshbach resonance.Comment: 7 pages, 3 figures. Extended versio
Recommended cereal varieties : 1969
Cereal varieties widely recommended for growing in 1969 are Gamenya and Falcon wheats, Dampier and Beecher barleys and Swan oats.
Other varieties include the new wheat Darkan, which is recommended only for the higher rainfall areas, the rust resistant wheats Mengavi and Gamut, and Irwin oats for late sowing in northeastern districts
Bussell barley
BUSSELL is a new high yielding 2-row barley variety named early in 1967.
An early maturing variety, with white grains of good quality, Bussell has short and extremely strong straw.
It has yielded more than any other variety under test in areas of Western Australia which receive more than 18 inches of annual rainfall.
It has yielded more than Prior in all areas
Mathematics and Morphogenesis of the City: A Geometrical Approach
Cities are living organisms. They are out of equilibrium, open systems that
never stop developing and sometimes die. The local geography can be compared to
a shell constraining its development. In brief, a city's current layout is a
step in a running morphogenesis process. Thus cities display a huge diversity
of shapes and none of traditional models from random graphs, complex networks
theory or stochastic geometry takes into account geometrical, functional and
dynamical aspects of a city in the same framework. We present here a global
mathematical model dedicated to cities that permits describing, manipulating
and explaining cities' overall shape and layout of their street systems. This
street-based framework conciliates the topological and geometrical sides of the
problem. From the static analysis of several French towns (topology of first
and second order, anisotropy, streets scaling) we make the hypothesis that the
development of a city follows a logic of division / extension of space. We
propose a dynamical model that mimics this logic and which from simple general
rules and a few parameters succeeds in generating a large diversity of cities
and in reproducing the general features the static analysis has pointed out.Comment: 13 pages, 13 figure
