The Relationship Of Applied Rock Phosphate On The Growth Of Sweet Corn, Deborah A. Sutherland Dec 1987

The Relationship Of Applied Rock Phosphate On The Growth Of Sweet Corn, Deborah A. Sutherland

Natural Resources Management and Environmental Sciences

Banding is a more intense application of fertilizers than broadcasting. Literature reviews have indicated that a higher amount of phosphorus in the root zone can enhance the growth and development of seedlings (Amin and Zaidi, 2004). Field trials on Sandy and Loam soils were conducted to test the effects of rock phosphate on sweet corn. These effects were investigated by studying the height, dry weight and phosphorus uptake of plants grown in soils banded with 0-90 lb P2O5/AFS. The results were moderate increases in plant height with applied rock phosphorus. The laboratory studies entailed oven drying forty day old ...


Low-Fat Dairy Coffee Whitener, Frank V. Kosikowski, Rafael Jiménez-Flores Aug 1987

Low-Fat Dairy Coffee Whitener, Frank V. Kosikowski, Rafael Jiménez-Flores

Dairy Science

A coffee whitener composition made from decreamed milk ultrafiltration retentate having its protein concentrated between about 2:1 to about 4:1 compared to the protein content of the starting milk and a minor whitening power enhancing amount is added in the form of riboflavin (a vitamin) and beta carotene (a vitamin pre-cursor) or a mixture thereof. The composition is usually in powdered form and is high in protein, low in fat and sodium and reduced in lactose and its high protein enhanced as described provided a low-fat dairy coffee whitening function approximately equal to non-diary coffee creamers.


Method For Removal Of Pharmaceutical Antibiotics From Contaminated Milks, Frank V. Kosikowski, Rafael Jiménez-Flores Aug 1987

Method For Removal Of Pharmaceutical Antibiotics From Contaminated Milks, Frank V. Kosikowski, Rafael Jiménez-Flores

Dairy Science

A method of removing penicillin G and/or pharmaceutical antibiotics which contaminated milk by:
(a) Subjecting the contaminated milk to an ultrafiltration process which produces a permeate containing the contamining antibiotic and a retentate comprising milk proteins and fats.
(b) Adding a non-antibiotic containing retentate diluting (washing) aqueous fluid including uncontaminated ultrafiltered milk permeate, uncontaminated whole milk, uncontaminated skim milk, or uncontaminated acid or sweet whey, or a mixture thereof to the retentate to dilute the retentate.
(c) Subjecting the diluted (washed) retentate to the ultrafiltration process from additional antibiotic containing permeate thereby forming a milk product comprising retentate having ...


Influence Of Prestress Environment On Annual Bluegrass Heat Tolerance, Dennis L. Martin, David J. Wehner May 1987

Influence Of Prestress Environment On Annual Bluegrass Heat Tolerance, Dennis L. Martin, David J. Wehner

Office of the Dean (CAFES) Scholarship

Annual bluegrass (Poa annua L.) turf quality is reduced during periods of high temperature. To predict heat stress injury and develop improved prestress maintenance practices, an understanding of the seasonal variation in annual bluegrass heat tolerance and the influence of soil moisture on heat tolerance is crucial. Annual bluegrass growing in the field on a Drummer silty clay loam (fine silty, mixed, mesic Typic Haplaquolls) was sampled on 23 dates over two growing seasons and brought to a laboratory for exposure to high temperature. Prestress environmental conditions (air and soil temperature, soil matric potential, plant water potential, daylength, rainfall and ...

The Effectiveness Of Lime-Based Amendments And Bauxite Residues At Removing Phosphorus From Piggery Effluent, D. M. Weaver, G. S. P. Ritchie Jan 1987

The Effectiveness Of Lime-Based Amendments And Bauxite Residues At Removing Phosphorus From Piggery Effluent, D. M. Weaver, G. S. P. Ritchie

Food Science and Nutrition

Piggery effluent may contribute to the eutrophication of waterways, if it is not treated before disposal, because of high levels of phosphorus. Limes and red muds (a residue from bauxite refining) were used to remove phosphorus from piggery effluent (41 mg litre-1 total P). Lime-based amendments were more effective than the red muds at removing phosphorus when compared at the same liquid: solid ratios. Based on laboratory data, the cost of treating effluent increased rapidly as the final required phosphorus concentration decreased to less than 4 mg litre-1. Kiln dust was the cheapest amendment tested down to 2 ...


Cloning And Sequence Analysis Of Bovine Β-Casein Cdna, Rafael Jiménez-Flores, Young C. Kang, Tom Richardson Jan 1987

Cloning And Sequence Analysis Of Bovine Β-Casein Cdna, Rafael Jiménez-Flores, Young C. Kang, Tom Richardson

Dairy Science

A bovine β-casein cDNA clone was isolated from a cDNA library prepared from mammary gland mRNA. Sequence analysis revealed 25 nucleotides (nt) of the 5′ noncoding region, 672 nt of the complete sequence coding and a 3′ region of approximately 500 nt. When the nucleotide sequence of bovine β-casein cDNA is compared to rat β-casein cDNA (5), a high degree of homology is observed in the first 100 nt corresponding to the signal peptide of the pre-β-caseins.
