Properties of isocalar-pair condensates

It is pointed out that the ground state of n neutrons and n protons in a single-j shell, interacting through an isoscalar (T=0) pairing force, is not paired, J=0, but rather spin-aligned, J=n. This observation is explained in the context of a model of isoscalar P (J=1) pairs, which is mapped onto a system of p bosons, leading to an approximate analytic solution of the isoscalar-pairing limit in jj coupling.Comment: 7 pages, 3 figures, 1 tabl

Fertilizers for potatoes in Manjimup and Pemberton areas

IN articles published in previous issues of the Journal each of a number of potato fertiliser trials carried out in the Manjimup and Pemberton districts has been discussed and results reported. This article briefly summarises the results of these trials carried out over the past four years and makes definite recommendations to potato growers in these districts regarding quantities of fertilisers to be used on new Red Karri loam soils

The Mystery of Justice Holmes

We have lived in an era of crusades, ideologies and causes. We whose lives extend into a second generation look back on causes and leaders of causes which were with us but not with those of the second generation. Such is not the fate of Justice Holmes. He continues, if only a subject of controversy. Two reasons for the continuity are apparent at once. He wrote well: “Worships language and forgives . . . Everyone by whom it lives,” and he wrote on law and justice—universals which interest everyone and which have inspired teachers from a time extending back through Aristotle and Plato. There is another reason for a continuing interest in Justice Holmes. It is not so apparent in our era. Time may develop it clear and sharp. We are conscious of it, though, through our inability to classify Justice Holmes. Some regarded him as a liberal, others have been sure that the Justice was a radical, and still others treated the Justice as a source of social and political mischief. This irritation may have found its source in the difficulty that arises when we look for a category that fits. What later generations may see clear and sharp is an objectiveness of mind that became notable in the Northern Securities litigation, and which leaves Justice Holmes in our era as a man without a cause. I propose to develop this thought by comparisons and contrasts with men who were working during that period; then I shall refer to the quality in the Justice’s work

Water erosion control - 3

Contour Bank is the name applied to a ridge or bank of earth built across sloping ground between points of equal or nearly equal heights. The basic function of a contour bank is interception of run-off water is then either absorbed or conducted slowly from the land, depending on the condition of the soil conservation work contour banks are not a substitute for, but supplementary to, suitable plant cover and careful land management

Broom millet in the market garden

WHEN we think of broom millet we usually regard it as a crop for growing either under flood irrigation or in summer moist swamps for the sole purpose of producing straw for brooms. However, the particular characteristics of the broom millet plant make it adaptable for use in the market garden as an excellent windbreak and rotation crop

Growing peas for canning and freezing in Western Australia

Canned and frozen peas to the total annual value of over a quarter of a million pounds are being imported into Western Australia from Eastern States. Could our requirements be supplied from crops grown in this State? The answer is Yes and this article gives a general background of information on pea growing and an indication of areas suitable for pea crops
