Petroleum-Wax Separation, Michael D. Ackerson, Seyed-Hamid Arabshahi, Robert E. Babcock Dec 1998

Petroleum-Wax Separation, Michael D. Ackerson, Seyed-Hamid Arabshahi, Robert E. Babcock

Patents Granted

A process for dewaxing is described. It includes the steps of mixing a waxy feedstock near its pour point with an ambient or below ambient temperature solvent essentially free of a selected cosolvent, to form a solvent/feedstock mixture, and subsequently adding the cosolvent to the solvent/feedstock mixture to cause instantaneous precipitation of wax on addition of cosolvent. The amount of wax precipitation is controlled by the quantity and temperature of the cosolvent added. The cosolvent is essentially completely miscible with the solvent, but immiscible with the oil and wax. For example, alcohols (methanol, ethanol, propanol), ketones (ketene, acetone), amines, etc. …

The Integration Of Firm Resources: The Role Of Capabilities In Strategy And Firm Performance, Daniel Lynch Dec 1998

The Integration Of Firm Resources: The Role Of Capabilities In Strategy And Firm Performance, Daniel Lynch

Graduate Theses and Dissertations

Distinctive capabilities are defined as a firm’s accumulated skills and knowledge that may lead to competitive advantage (Day 1994). Distinctive capabilities are founded upon Resource-Based Theory (Barney 1991) that focuses on internal resources as opposed to external market forces (Porter 1980). The present research discusses the integration of distinctive capabilities into this framework; that is, do certain distinctive capabilities (resources) create superior firm performance when linked to the appropriate generic business strategy?

The literature on firm performance has a rich history and is theoretically grounded in several disciplines including economics, sociology, and organizational behavior (Anderson 1982). However, there has not …


Accounting Expertise And Ill-Structured Problems: Cognitive Reasoning Abilities And Performance In Business Valuation Tasks, Wray Bradley Dec 1998

Accounting Expertise And Ill-Structured Problems: Cognitive Reasoning Abilities And Performance In Business Valuation Tasks, Wray Bradley

Graduate Theses and Dissertations

This study investigates the linkage between cognitive reasoning abilities and performance in ill-structured tasks. Prior accounting research shows that the broad construct known as general problem-solving ability is directly related to performance in ill-structured audit tasks (Libby and Tan 1994). General problem-solving ability has been defined as having sub-components comprised of verbal, quantitative, memory, and cognitive reasoning abilities (Libby 1995). Most prior accounting studies have either controlled for performance differences associated with the subcomponent abilities or have just ignored them. This has created a gap in behavioral accounting research (Shanteau 1995; Bouwman and Bradley 1997). This study seeks to partially …

Storm And Base Flow Water Quality For Bear, Calf, And Tomahawk Creeks, Kenneth F. Steele, David N. Mott

Technical Reports

Because of the conversion of 92,780 acres of forest to pasture land in the Buffalo River watershed over a 27 year period, there is concern about the affect of agricultural activities on the water quality of the river. Three tributaries (Bear, Calf and Tomahawk creeks) located about mid-length of the Buffalo River were chosen to investigate the affect of agricultural activity on water quality because these streams provide the greatest amounts of fecal bacteria, nitrate+nitrite and phosphorus to the river, despite comprising only 13% of the watershed.

Serological Detection And Identification Of Rice Blast, Fleet N. Lee, Howard A. Scott, Jun Q. Xia

Patents Granted

Monoclonal antibodies (MAbs) useful in the serological detection and identification of rice blast were produced by hybridoma cells formed from fusions of myeloma cells with splenocytes from BALB/c mice immunized with an extract of a liquid culture fluid of an isolate of Pyricularia grisea race IB-49. These MAbs reacted similarly with the antigens in various serological techniques used, and did not cross react with any unrelated fungal isolates representing 11 genera, but reacted positively with all 20 races or isolates of P. grisea. The MAbs could detect homologous antigen at about 60 ng fungal protein/ml and a 5-fold dilution of …
