Model For Estimating The Probability Of Crop Production For Ginkgo Biloba L., Michael I. Johnson

Journal of the Arkansas Academy of Science

Mature female Maidenhair trees (Ginkgo biloba L.)have been observed to produce seed dispersal units in some years and none in other years. A temperature and/or photoperiod flowering threshold is suggested. Daily temperatures and daylengths at five Ginkgo sites in continental U.S. for January-April 1964-1974 were evaluated. A computer program was designed to estimate daily photothermal equivalent (PTE = temperature and photoperiod), and the magnitude and duration of the PTE in relation to a series of photothermal constants. Use of the data from production and nonproduction years provided a mathematical model for prediction of dispersal unit production. The model was tested …

Fisheries Report No 18 - Tuna Survey In Waters Off The Western Australian Coast During The Period August 1973 To August 1974, J. P. Robins

Fisheries Research Reports

In September 1972, Markwell Ross Fisheries Pty Ltd (a subsidiary fishing division of Q.U.F. Industries Ltd) approached the Western Australian Department of Fisheries and Fauna (now Department of Fisheries and Wildlife) for assistance in the development and carrying out of a purse seining programme using the 25m rock lob­ster vessel F.B. Western Star.

Negotiation and agreement was reached, with the objective to under­take and carry out an investigation into the feasibility of developing a purse seine fishery for tuna in Western Australian waters. The Department of Fisheries and Wildlife (Development Section) supplied, on loan, capital fishing equipment (purse seine net, …

Fisheries Report No 16 - Notes On The Wildlife Of A Proposed Nature Reserve Around Lake Grace And Lake Chinokup, Western Australia, N. L. Mckenzie, W. K. Youngson

Fisheries Research Reports

During 1972 and 1973 plants and vertebrate animals were collected and recorded from a proposed 22 000 ha nature reserve centred on a chain of salt lakes in south-western Western Australia (33° 10' S - 33° 35' 8 and 118° 19' B - 118° 29' E).

The dominant plant species were collected, the structural formations desert bed and a vegetation map produced. Seven species of native terrestrial mammal and three species of bat were recorded.

Three of the terrestrial species are endemic to southwestern Western Australia, and two of these - Pseudomys occidentalis and Sminthopsis granulipes - are regarded as …

Fisheries Report No 17 - Some Aspects Of Tuna And Its Potential In The Oceanic Waters Off Western Australia, J. P. Robins

Fisheries Research Reports

In this report an endeavour has been made to describe very briefly the growth of the tuna fishery in Australia, world production, utilisation, price and future demand, tuna species descriptions, species occurrence around the Australian coast and the results of two aerial surveys for tuna off. the west and north-west coasts of Western Australia.

Decide : How Much Superphosphate, G A. Robertson, J. W. Bowden, N. J. Halse

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

* A 400 per cent increase in ihe price of superphosphate has reduced the economic optimum rates of super for crops and pastures in 1975.

* Many factors, both biological and economic, must be taken into account in determining the rate of superphosphate to apply.

• DECIDE, a model developed by CSIRO and the Department of Agriculture, provides a formal system in which all these factors can be considered.

• DECIDE is based on the results of all research on superphosphate carried out in Western Australia. However, each farmer's own knowledge of his farm, the soils, crops and animals is …

The Application Of Linear Programming In The Design Of Least Cost Furnishes For Paper Making Systems, George M. Iverson

Paper Engineering Senior Theses

Linear programming is a mathematical technique used to optimize complex physical processes. Due to rising pulp costs, the need to minimize the costs of raw materials in paper furnishes is acute. This paper studies the potential of linear programming as a tool to design furnishes meeting designated paper specifications while minimizing raw material costs. The flexibility of linear programming is discussed and the applicability of linear models describing multi-component furnishes with their effect on paper properties is investigated. Some paper properties were found to fit well with the linear model. Some of these were opacity, smoothness, tensile, mullen, and tear. …
