measurement of oxygen transfer in clean water

this method covers the measurement of the oxygen transfer rate (otr) as a mass of oxygen per unit time dissolved in a volume of water by an oxygen transfer system operating under given gas rate and power conditions. methods for measurement of gas rate and power are also described in the annexes a and b, respectively. the method is applicable to laboratory-scale oxygenation devices with small volumes of water as well as the full-scale system with water volumes typical of those found in the activated sludge wastewater treatment process. the procedure is valid for a wide variety of mixing conditions. the primary result of this test is expressed as the standard oxygen transfer rate (sotr), a hypothetical mass of oxygen transferred per unit of time at zero dissolved oxygen concentration, water temperature of 20°c, and barometric pressure of 1.00 atm (191kpa), under specified gas rate and power conditions. the method is intended primarily for clean water meeting the requirements of section 5.2 and 6.3. the results can be applied to estimate oxygen transfer rate in process water as described in commentary.

The primaryuse of such insects is in the Sterile Insect Technique, wherelarge numbers of reproductively sterile insects are released intothe field to mate with and thus control pest populations of thesame species. A secondary use of sterile insects is as benignhosts for rearing insect parasitoids. The procedures outlined inthis guide will help ensure that insects processed with ionizingradiation from gamma, electron, or X-ray sources receiveabsorbed doses within a predetermined range. Information oneffective dose ranges for specific applications of insect steril-ization, or on methodology for determining effective doseranges, is not within the scope of this guide.NOTE 1—Dosimetry is only one component of a total quality assuranceprogram to ensure that irradiated insects are adequately sterilized and fullycompetitive or otherwise suitable for their intended purpose.

For the last three decades,the STL file format has been the industry standard for trans-ferring information between design programs and additivemanufacturing equipment. An STL file contains informationonly about a surface mesh and has no provisions for represent-ing color, texture, material, substructure, and other propertiesof the fabricated target object. As additive manufacturingtechnology is quickly evolving from producing primarilysingle-material, homogenous shapes to producing multimate-rial geometries in full color with functionally graded materialsand microstructures, there is a growing need for a standardinterchange file format that can support these features.
