Analysis Of Biodiesel Quality Using Reversed Phase High-Performance Liquid Chromatography, Kellyann M. Murphy

Pomona Senior Theses

The alternative fuel biodiesel is produced from the transesterification of vegetable oils or animal fat to fatty acid methyl esters. Pomona has a reactor on campus that can be used to run this reaction and produce biodiesel. The use of biodiesel has been found to lower air pollutant and greenhouse gas emissions, but can be potentially harmful to the engines if it contains impurities. This paper proposes a method using high-performance liquid chromatography to test the quality of biodiesel. This method utilizes instrumentation and materials that are available in Pomona College's Chemistry Department, requires very little sample preparation, and is …

Fisheries Research Report No.196 - Management Of Bioeroding Sponges In Wild Stocks Of Pinctada Maxima In Western Australia, Sabine Daume, Jane Fromont, Anthony M. Hart

Fisheries Research Reports

Final FRDC Report – Project 2005/074

The Western Australian fishery is the only remaining significant fishery for pearl oysters in the world and comprises most of the exported pearl product of Australia, currently worth around $125 million annually. The majority of pearl shells used to culture pearls come from the pearling beds in the inshore waters near Broome. The fishery for pearl oysters preferentially targets smaller ‘culture’ shell (4-5 years age class, 120mm - 160mm shell length) that are more suitable for growing pearls, leaving larger MOP oysters (6+ age class, 175mm+) on the fishing grounds.

Silver-lipped pearl oysters (Pinctada …

Horticulture Research Report 1994 - 1998, Frank Wise Institute, Kununurra, Department Of Agriculture, Western Australia, D. Robinson, M. Howes, R. Randell

Horticulture research reports

This report summarises horticultural research, development and extension activities undertaken by staff from the Kununurra District Office during the period 1993 to 1998 and reported annually at the Frank Wise Institute Horticultural Research Review. The range and extent of activities presented and supported by Agriculture Western Australia with industry collaboration indicates the importance of horticulture in the economies of the Kimberley Region and Western Australia. Further support by funding bodies and agribusiness, and collaboration with other research organizations is also acknowledged. Since the early 1980's, horticultural output and value of production from the Ord River Irrigation Area (ORIA) have risen …

Western Australian Fisheries - Key Achievements 1997-1998, Fisheries Western Australia

Fisheries Published Reports

The WA fishing community can look back at the past year with considerable satisfaction.

Close partnership arrangements between Government, industry, the community and Fisheries Western Australia have both consolidated and advanced the State's position at the forefront of sustainable management of marine environments and fish resources.

Together, commercial fishing and recreational fishing make 􀁚 annual $1.5 billion contribution to the Western Australian economy. Through a carefully balanced portfolio of policies and initiatives the Coalition is making sure that both sectors continue to prosper, while at the same time ensuring that future generations inherit a marine environment which we are all …

1991 Catalogue Of The Australian Lupin Collection Including Field Evaluation Data For Wild, Semi-Domesticated And Fully Domesticated Accessions, J. C. Clements, W. A. Cowling

Grain and other field crops research reports

This report lists all wild, semi-domesticated and fully domesticated accessions in the Australian Lupin Collection to 1991. The Collection is composed of 2,264 accessions (Perth Numbers between 20629 and 27067) introduced to Australia or from naturalized populations and breeding programmes within Australia. Several accessions are selections from variable populations which were identified during field trials in South Perth, Western Australia. This catalogue lists the characteristics and field evaluation data for every accession where available. Plant breeders and crop scientists will find this information useful for the selection of lupin genotypes with desired characteristics.

Section A of this catalogue should be …

Estimation Of Food Limitation In Daphnia Pulex From Boulder Basin, Lake Mead, Thomas Mark Bartanen

Publications (WR)

In February, 1982 I began a year-long study to determine if growth and reproduction in Daphnia Pulex were limited by the amount of food available in Boulder Basin, Lake Mead. To determine this, I made monthly collections of Daphnia Pulex and natural lake seston from an already established station in Boulder Basin. I cultured the Daphnia Pulex under simulated field conditions in a flow-through feeding apparatus using four different food regimes; 1-natural lake seston filtered through 80 um mesh to remove other zooplankton, 2-lake seston (as above) with an enrichment of 10³ cells-ml^-1 of Chlamydomonas reinhardti, 3-lake …

Grain Crop Variety Trials Western Australia 1978-1979, H. M. Fisher, G. B. Crosbie

Grain and other field crops research reports

The regional crop variety testing programme conducted by the Western Australian Department of Agriculture covers the final two stages of a four stage process of evaluating locally produced crossbreds and introduced material comprising:-

Plant Breeder Trials

Stage 1: Initial small plot yield tests on early generation material - 1 to 3 sites. Stage 2: Small plot yield tests on selected material (F5 derived) - 3 to 4 sites.

Regional Testing Programme

Stage 3: Large scale preliminary trials - 9 to 10 sites. Stage 4: Large scale final yield trials - 40 to 50 sites.

The basis of the regional programme …
