The role of ascorbic acid on discoloration of strawberry juice and concentrate

Creator:: Poei, Metty Soek-Kioen
Abstract:: The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate. The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...

k+̄p [forward arrow] k⁰+[uppercase xi]⁰ differential cross section measurement at 1.8 GeV/c

Creator:: Carlson, James Robert
Abstract:: The differential cross section for the reaction k⁻+p[forward arrow] k⁰+[uppercase xi]⁰ was measured in a spark chamber experiment for an incident k⁻ momentum of 1.8 GeV/c. The target was liquid hydrogen confronted by an anti-coincidence counter to insure neutral particle production. A 60 element hodoscope signalled the presence of four...

Carbene chemistry : I. Stereochemical integrity at Cα in ketone tosylhydrazones : II. Hydrogen migration in 2-carbena-6, 6-dimethylnorbornane

Creator:: Balyeat, John Robert
Abstract:: The tosylhydrazones of exo-3-deuteriocamphor and 2- deuterio-2,4-dimethy1-3-pentanone were treated with Nbromosuccinimide (NBS) and pyruvic acid to regenerate the parent ketones. The ketones from the pyruvic acid cleavage show a significant loss of deuterium. The ketones from the NBS cleavage show no loss of deuterium, indicating that stereochemical integrity at.

Aeromonas salmonicida and aeromonas hydrophila (liquefaciens) as pathogens of salmonid fish. A. Selective aeromonas medium. B. Comparative characteristics of virulent and avirulent strains of aeromonas salmonicida. C. Effect of water temperature on aeromonas infections

Creator:: McCoy, Ralph Hines
Abstract:: Studies were directed toward the formulation of a selective Aeromonas medium that would permit the isolation of Aeromonas species in the presence of other common bacterial flora. The final composition of this medium, PBG Agar, in grams per liter, is: Bacto-peptone, 10; Bacto-beef extract, 10; glycogen, 4; NaCl, 5; sodium...

Freezing resistance of tissues in the twig of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Alden, John Norman
Abstract:: The relative freezing resistance of tissues in the stem, foliage and buds of terminal twigs from Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) was investigated at about ten-day intervals from summer until the following spring. Tissues from growing twigs collected before development of dormancy had no freezing resistance and were killed immediately...

Biological preparation of ¹⁴C labeled aflatoxin

Creator:: Schoenhard, Grant Louis
Abstract:: Selected parameters that affect crude toxin production in both primary culture (growing cell culture) and resting culture were examined during efforts to produce sufficient crude toxin for purification. The parameters included carbohydrate and label source and concentration, cell concentration, incubation time and temperature and shaker speed. A higher yield of...

An evaluation of soil warming for increased crop production

Creator:: Rykbost, K. A.
Abstract:: In regions where soil temperatures limit plant growth, artificial soil warming may be an economically feasible practice. This hypothesis was evaluated in a soil warming experiment near Corvallis, Oregon. This experiment was prompted by the observation that multiple use of waste heat discharged in the condenser cooling water of thermal...
