- 1 May 2004
Exposure atmospheres for a rodent inhalation toxicology study were generated from the exhaust of a 2000 Cummins ISB 5.9L diesel engine coupled to a dynamometer and operated on a slightly modified… Expand
Interspecific scaling of toxicity data.
This paper reexamines the scaling approaches used in cancer risk assessment and proposes a more precise body weight scaling factor. Two approaches are conventionally used in scaling exposure and dose… Expand
EFFECTS OF SUBCHRONIC INHALATION EXPOSURE OF RATS TO EMISSIONS FROM A DIESEL ENGINE BURNING SOYBEAN OIL-DERIVED BIODIESEL FUEL
There is increasing interest in diesel fuels derived from plant oils or animal fats ("biodiesel"), but little information on the toxicity of biodiesel emissions other than bacterial mutagenicity.… Expand
Design, Characterization, and Evaluation of a Small-Scale Diesel Exhaust Exposure System
A single-cylinder engine diesel exhaust exposure system was constructed to conduct laboratory health effects studies. The single-cylinder engine was selected to provide a cost-effective and… Expand
Managing Runoff from a Small, Paved Beef Feedlot
Each year for 3 y, 56 steer calves were fed to market weight on a corn-silage and shelled-corn ration in a 243-m² paved lot. Storm runoff was measured and sampled as it left the feedlot, and again… Expand
Inhalation exposure systems for the development of rodent models of sulfur mustard-induced pulmonary injury
Sulfur mustard (SM) is a chemical threat agent for which its effects have no current treatment. Due to the ease of synthesis and dispersal of this material, the need to develop therapeutics is… Expand
Simulation Model for Composting Cellulosic (Bagasse) Substrates
A dynamic model of aerobic composting with solid substrates was developed as a first step to predict the rate of decomposition of cellulosic materials. The model was based on heat and mass transfer… Expand
Generation and Characterization of Hardwood Smoke Inhalation Exposure Atmospheres
An inhalation exposure system and operating protocol were developed that resulted in consistent achievement of targeted exposure concentrations of hardwood smoke without compromising the desire to… Expand
Right-Left Ventricular output Balance in the Totally Implantable Artificial Heart

- The International journal of artificial organs
- 1 June 1991
Pneumatically powered artificial hearts readily accommodated the higher net stroke volumes by the right ventricle than from the left ventricle. We published that this discrepancy was approximately 8%… Expand
Quantitative standard for exposure chamber integrity.
- B. V. Mokler, R. K. White
- Chemistry, Medicine
- American Industrial Hygiene Association journal
- 1 April 1983
An inhalation exposure chamber separates the internal exposure atmosphere from the surrounding laboratory atmosphere. The integrity of this separation is reduced if the chamber leaks. A simple method… Expand
