Beef cattle studies - Narra Tarra, Geralton, W.A.

Beef cattle studies were carried out at Narra Tarra, Geraldton, between April 1951 and March 1955. These were part of a project established in the southern States of Australia to obtain factual data on the growth performance of cattle under existing systems of management and thereby to indicate ways and means for increased efficiency in beef production. Three centres were established in the south-western portion of Western Australia and of these, the most northerly was that on Narra Tarra, the property of Messrs. E. & F. Green

Sheep grazing experiment with mown and unmown pasture, Chapman Research Station, 1958-1959

INVESTIGATIONS carried out several years ago at the Avondale, Chapman and * Wongan Hills Research Station showed that increased wool yields and reduced liveweight losses could be obtained by grazing sheep on pasture which had been mown at the hay stage and left in the paddock instead of allowing it to mature and dry off normally

Effect of Lacto-Ovo and Total Vegetarian Diets on Serum, Urinary and Fecal B₁₂ Levels

Serum, urinary and fecal levels of ten lacto-ovo-vegetarians and nine total vegetarians were assayed using Ochromonas malhamensis. Intakes of vitamin B12 , protein, fat, carbohydrates, fiber and calories were calculated using 7-day diet histories and questionnaires. Correlations between nutrients consumed, years on diet, serum, urinary and fecal B12 levels were also calculated. Mean serum B12 levels of the lacto-ovo-vegetarians and total vegetarians were 657 pg/ml and 381 pg/ml respectively. There was no significant difference between the two groups. The average daily intake of vitamin B12 was 2.0 ug for lacto-ovo-vegetarians and 0.6 ug for the total vegetarians. When nutrients were expressed as percent of calories, the total vegetarians consumed a significantly smaller percent of calories as protein, but there was no significant difference in the percent of calories consumed as fat or carbohydrate or in the percentage of required calories consumed. When nutrient intake was expressed as grams per day. the total vegetarians consumed significantly fewer grams of protein and fat and significantly more grams of fiber than the lacto-ovo-vegetarians. Beth groups consumed fewer calories than required, but the total vegetarians consumed significantly fewer calories than the lacto-ovo-vegetarians. There was no significant difference in the amount of urine excreted by the two groups, but the total vegetarians excreted a significantly greater amount of feces. This is probably a result of the greater fiber intake by the total vegetarians. There was no significant difference in the amount of B12 excreted in the feces or urine of the two groups. A positive correlation was found between the percentage of calories as protein in the diet and the level of result of an increased synthesis of the transcobalamin proteins. There in the serum. This may be a were no other significant correlations between serum B12 and dietary components, but in the lacto-ovo-vegetarians there was a positive correlation between serum B12 and fecal B12. A positive correlation was also found between serum B12 and the period of time on a total vegetarian diet; serum B12 increased as the number of years on the diet increased. This study concludes that the amount of vitamin B12 consumed by a total vegetarian can be adequate to maintain serum B12 unless the individual has extra needs (infants or the elderly). The need for dietary B12 can be met with a balanced diet containing adequate protein and B12 fortified plant foods

Relating Statistical Image Differences and Degradation Features

Document images are degraded through bilevel processes such as scanning, printing, and photocopying. The resulting image degradations can be categorized based either on observable degradation features or on degradation model parameters. The degradation features can be related mathematically to model parameters. In this paper we statistically compare pairs of populations of degraded character images created with different model parameters. The changes in the probability that the characters are from different populations when the model parameters vary correlate with the relationship between observable degradation features and the model parameters. The paper also shows which features have the largest impact on the image

The Fermionic Quantum Emulator

The fermionic quantum emulator (FQE) is a collection of protocols for emulating quantum dynamics of fermions efficiently taking advantage of common symmetries present in chemical, materials, and condensed-matter systems. The library is fully integrated with the OpenFermion software package and serves as the simulation backend. The FQE reduces memory footprint by exploiting number and spin symmetry along with custom evolution routines for sparse and dense Hamiltonians, allowing us to study significantly larger quantum circuits at modest computational cost when compared against qubit state vector simulators. This release paper outlines the technical details of the simulation methods and key technical advantages

Centralised Design and Production of the Ultra-High Vacuum and Laser-Stabilisation Systems for the AION Ultra-Cold Strontium Laboratories

This paper outlines the centralised design and production of the Ultra-High-Vacuum sidearm and Laser-Stabilisation systems for the AION Ultra-Cold Strontium Laboratories. Commissioning data on the residual gas and steady-state pressures in the sidearm chambers, on magnetic field quality, on laser stabilisation, and on the loading rate for the 3D Magneto-Optical Trap are presented. Streamlining the design and production of the sidearm and laser stabilisation systems enabled the AION Collaboration to build and equip in parallel five state-of-the-art Ultra-Cold Strontium Laboratories within 24 months by leveraging key expertise in the collaboration. This approach could serve as a model for the development and construction of other cold atom experiments, such as atomic clock experiments and neutral atom quantum computing systems, by establishing dedicated design and production units at national laboratories.Comment: 27 pages, 21 figure

Terrestrial Very-Long-Baseline Atom Interferometry:Workshop Summary

This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around the world to discuss the exciting developments in large-scale atom interferometer (AI) prototypes and their potential for detecting ultralight dark matter and gravitational waves. The primary objective of the workshop was to lay the groundwork for an international TVLBAI proto-collaboration. This collaboration aims to unite researchers from different institutions to strategize and secure funding for terrestrial large-scale AI projects. The ultimate goal is to create a roadmap detailing the design and technology choices for one or more km-scale detectors, which will be operational in the mid-2030s. The key sections of this report present the physics case and technical challenges, together with a comprehensive overview of the discussions at the workshop together with the main conclusions

My Father\u27s Son

The Cross is heavy in my hand. Dull bronze gun metal moulded from the captured Russian guns of the Crimean War, it bears the weight of time past. There is the memory of victory and defeat in its cold form. The tangled purple ribbon, modest among the bright campaign medals of the Hrst World War, called the Great War, \u27the war to end wars\u27, speaks of my father\u27s courage, and his defeat by life. Turn it over. His name is carved into the steel. 2nd Lieut. H.V.H. THROSSELL A.J.F. 1915
