Change Acceleration Program

The threshold curves obtained when the accelerating potential between OR and Q2 was changed over a wide range from the onset of a given production to its maximum intensity were fitted with the theoretical cross section program, CRUNCH, developed by Armenrout and coworkers,67-69 which leads to a determination of the threshold energies (see Section IV.C). 

We have seen in a number of situations that such perspectives allow short diagnostics (i.e., of around one week) to be conducted, which lead to clear targets and identification of the main improvement levers. This results in heavy front-end loading of operational programs and accelerates change. 

PHREEQC always refers to one liter or one kg of water. The model describes a batch reaction with 1 liter water. 10 mmol calcite as well as 1 mol pyrite and 1 mol organic matter shall be present in the respective sediment/rock. To describe the kinetics of calcite and pyrite, the BASIC program given at the end of the data set PHREEQC.dat is used. For the degradation of organic matter the PHREEQC.dat notation is used, too. However, the lines 50 and 60 have to be changed as follows to accelerate the decomposition of the organic matter. Nitrate is not taken into account in this example. 

Test Methods. Tests for water repeUency of concrete and masonry have been described by several authors (72,94). The National Bureau of Standards (NBS) evaluated fifty-five clear water repeUents for masonry surfaces (95). Performance tests included water absorption, water-vapor transmission, resistance to efflorescence, change in appearance, and durability to accelerated and outdoor weathering. More recently, the National Cooperative Highway Research Program conducted a study of several organic and sihcone water-repeUent treatments. The results are communicated in Report 244 (96). The testing procedure used in this study is now a popular method for evaluating water-repeUent treatments on concrete.
