Coccoliths from the Cretaceous-Tertiary boundary of the Walvis Ridge, South Atlantic : biostratigraphic and paleoecological implications
(1989)
Biostratigraphy, diversity, and oxygen and carbon isotopes are determined for calcareous nannoplankton from four sections of Cretaceous-Tertiary boundary interval sediments on Walvis Ridge in the South Atlantic (DSDP Sites ...
Genotype mixtures for control of leaf rust of wheat
(1990)
Three-component mixtures of wheat genotypes were evaluated for yield performance and effectiveness of control of wheat leaf rust, caused by Puccinia recondita Rob ex Desm. The studies were conducted in the 1985-86 and ...
Mass spectrometric characterization of water soluble organics in heavy oil retort
(1994)
A unified scheme is developed to demonstrate the necessity of a synergistic approach using several mass spectrometry methods for characterization and identification of water soluble organics in heavy oil retort. Elements ...
Synthesis of wide pore crystalline aluminophosphates
(1991)
Three of the widest pore aluminophosphate molecular sieves were synthesized, H1, VPI-5 and AIPO[4]-8, and three more layer compounds were observed. These are the most important compounds in the search for new porous ...
Molecular characterization of interferon genes in cattle
(1992)
In this study, the genetic and physical mapping of bovine α (IFNA), [β (IFNB), ω (IFNO), trophoblast (IFNT) and Υ (IFNG) interferon gene families, the characterization of individual genes and alleles within each IFN ...
Improved methods for extracting and recovering asphalts from pavement samples
(1993)
Two new procedures for the purpose of extracting asphalt binder from hot-mix and pavement samples have been developed. Flaws in previous methods include: 1) the inability to completely remove solvent from recovered asphalt, ...
Validation of a technique for the assessment of occupational exposure to methanol vapor
(1993)
Studies of the performance of a technique for the assessment of occupational exposure to methanol vapor were completed. This air sampling technique utilized carbon molecular sieve contained in a stainless steel tube for ...
An analysis of alternative rice policies in Taiwan
(1991)
Most activities of the rice industry in Taiwan are affected by rice policy. Accordingly, it is important to impose an appropriate rice policy. Previous research indicates that rice policy has had different major objectives ...
Endogenous factors and mechanisms that confer resistance to Salmonella enteritidis infectivity in the intestinal tract of Leghorn chickens
(1992)
Four experiments are reported to explain some of the endogenous factors and mechanisms which confer resistance to Salmonella enteritidis (SE) infectivity in the intestinal tract of Leghorn chicks: (A) The effects of 14 or ...
The effect of three different goal setting methods on bench press strength performance
(1992)
An established message reported by behavioral scientists, who have conducted industrial research, is that performance can be enhanced through the use of goal setting. Locke, Shaw, Saari, and Latham (1981) reported, "The ...
