Distortions to travel cost derived demand curves : water quality and durable goods

Creator:: Garifo, Susan E.
Abstract:: The travel cost method of deriving demand and value of recreation does not include fixed costs of recreational durable goods purchases or allow for supply restrictions on the number of suitable sites available. The omission of these two real-world situations results in derivation of demand curves which are more inelastic...

Use of alkali in the isolation and preparation of aflatoxins

Creator:: Chen, Tsun-Chieh
Abstract:: The biological preparation of aflatoxins was accomplished by culturing the mold Aspergillus flavus on various media. Aflatoxin was isolated by chloroform extraction of the culture, and purified by column fractionation and crystallization. Rice, wheat, soya bean, peanut and YES media were found to give high yields of aflatoxin. It was...

Development of structural layer coefficients for open graded asphalt emulsion mixes

Creator:: Hatch, David Russell
Abstract:: This paper describes the development of structural layer coefficients for open graded asphalt emulsion surfacing layers which can be used with the AASHO pavement design method, as modified by the U. S. Forest Service, Region 6. A field survey conducted to document the history, performance and material characteristics of in-service...

Feed conversion, protein utilization and growth of rainbow trout (Salmo gairdneri) fed 25 to 45 percent herring oil

Creator:: Kellems, Richard O.
Abstract:: Triplicate groups of rainbow trout (Salmo gairdneri) fed six diets; five based on fish protein concentrate (FPC) ranging in caloric density from 4.36 to 6.19 kcal/g, and one based on vitamin free casein with a caloric density of 5.26 kcal/g were evaluated with respect to diet ingredient utilization. The parameters...

Population dynamics, extraction, and response to nematicide of three plant parasitic nematodes on peppermint (mentha piperita L.)

Creator:: Merrifield, Kathryn J.
Abstract:: The efficiencies of wet sieving/sucrose centrifugation (WS/SC) recovery of Pratylenchus penetrans (59 %), Paratylenchus sp., (80 %), and Criconemella xenoplax (66 %) were established. Baermann funnels (BF) recovered significantly more P. penetrans (p = 0.01) and significantly less (p = 0.01) C. xenoplax than did WS/SC. While densities of P....

The effects of harvesting Pacific hake (Merluccius productus) on the offshore community : the results of a multi-species model

Creator:: Gartz, Russell G.
Abstract:: The effects of harvesting Pacific hake (Merluccius productus) were examined with a multi-species numerical model composed of seven logistic growth equations coupled by a food web. The food web was composed of: California sea lions (Zalophus californianus), hake, sablefish (Anaplopoma fimbria), spiny dogfish (Squalus acanthias), a generic rockfish species (Sebastes...
