... the permeability, P , and the component parts, the diffusion coefficient, D , and the solubility coefficient, S , for selected flavor molecules. Use of these parameters to estimate flavor loss is included. The effects of temperature, humidity, concentration of the flavor, combination of flavors, size...

... The safe practice of inhalation anesthesia requires control over the amount of volatile anesthetic delivered to the patient. This is facilitated by continuous monitoring and recording of the agents' concentration (“anestheticography”). Either the vaporizer or the circuit may be considered...

... was examined using the scanning electron microscope. The effects of slurry concentration (solids loading), velocity, and target material were noted. Evidence of erosion-corrosion was observed for slurries with added stabilizers and for water-based slurries. The erosivity increased in the order coke-oil, coal...

... Metal concentrations in rivers and streams vary continually. An indicator of toxic trace metals is needed to establish recent maximum levels. An initial study was conducted during the summer of 1979 on Coal Creek and Slate River, Gunnison County, Colo., to test whether aquatic insects could...

... The concentrations of a wide variety of organic compounds present in working environments may be determined easily and inexpensively using diffusion dosimetry. Personal and area monitoring, resulting in data similar to that obtained with charcoal tubes, are accomplished without using pumps...

... of stain indicator. The stain length developed in a given period of time is compared to a calibration chart to determine, on the spot, the average gas concentration to which the dosimeter has been exposed. These dosimeters are known by the trade name Vapor Gard. analyzers absorbents colorimetric...

Eighty-four water and thirty-two sediment samples were analyzed for heterotrophic bacterial concentrations using the four methods under study. A statistical analysis of the data by a factorial analysis of variance...

... This paper describes, by way of introduction only, the U.K. response capability for oil spill clearance and outlines the reasons for choosing a dispersant approach. The paper then concentrates on the details of the system used to render the dispersant approach operational. The methods...
