Priority designations

The terms erythro and threo may be defined in a different fashion using the R and S priority designations and Newman prelections reference 95 reference 117. See also Seebach, D. Prelog, V. Angew. Chem. Int. Ed. Engl. 1982,21,654 Gielen, M. /. Chem. Educ. 1977,54,673. 

A methodology for the rapid assessment of emergency care priorities. Triage involves the sorting and allocation of treatment to patients, especially disaster victims, according to a system of priorities designed to maximize the number of survivors. 

The highest priority designation is assigned to the OBR2 group w ith enolate substituents. 

To simplify matters, we replace the substituents with their stCTeochemical priority designators ... 

Control technology requirements vary according to the scale of operation and type of emission problem. For instance, electrostatic precipitator design requirements for fly-ash control from 1000-MW coal-fired power boilers differ from those for a chemical process operation. In the discussion that follows, priority is given to control technology for the CPI as opposed to the somewhat special needs of other industries. 

The arrest of deterioration and the prevention of its recurrence has higher priority than restoration. Thus, identification of the causes of a problem and the design of measures to stabilize and consoHdate the object are primary considerations. Removal of the symptoms and restoration of the visual appearance comes only after the physical iategrity has beea safeguarded. 

If the observed order of priority of the remaining three functions (a > 6 > c) is in a clockwise direction, the absolute configuration is designated R (rectus or right) if counterclockwise, the configuration is S (sinister or left). The concepts of stereochemistry and chiraUty have been extensively discussed and reviewed (27—29). 

Design data are available for the specific organics on the EPA s priority pollutant Hst. For mixed wastewaters, a laboratory study is necessary to determine adsorption characteristics. Wastewater is contacted with a range of concentrations of powdered carbon and adsorption occurs, as graphed ia the form of a Freundhch Isotherm, shown ia Figure 19. 

Antimony may enter the human body through the consumption of meats, vegetables, and seafood which all contain about 0.2—1.1 ppb antimony. Disposal of Antimony. Antimony and its compounds have been designated as priority pollutants by the EPA (35). As a result users, transporters, generators, and processors of antimony-containing material must comply with regulations of the Eederal Resource Conservative and Recovery Act (RCRA). 

The proeess eapability requirements for eomponent eharaeteristies determined by CA are used to support the supplier development proeess. In the approaeh, new designs of bought-in parts sueh as eastings, plastie mouldings and assembly work are diseussed with proeess eapability requirements as the first priority. Where a potential problem with the toleranee on a eharaeteristie has been identified, this...
