Water introduction

Finally, an excess aqueous phase may not lead to inactivation if the method of enzyme and water introduction into nonaqueous media is performed carefully. It is best to introduce enzymes (after their lyophilization at optimal conditions, as discussed above) as highly concentrated aqueous solutions ( 60 mg/ml) into organic media rather than to add solid-phase enzymes to micro-aqueous solvents. - ° Such a procedure was particularly effective for incorporating highly purified lipase into nonaqueous media, in contrast to previous results indicating such purified hpases are highly inactive. ...

The population equivalent is a conventional unit which does not express all the properties of industrial wastewaters. Moreover, their values vary at each change in the production technology which has an impact on the composition of wastewaters (e.g. changes such as saving of water, introduction of recirculation, etc.). The quoted values of population equivalents differ, therefore, quite considerably in the literature. 

Damage to trays occurred at shutdown. The damage was caused by eiqxising colimm internals to cold water and air prematurely. Steam cooling of the tower was not adequate prior to air and water introduction. 

Four new benzamido-functionalized prolinamides act as organocatalysts for aldols of aldehydes and cyclic ketones in water, with de/ee up to 96/98%, suggesting that while lateral amide functionality facilitates selectivity in water, introduction of additional chirality into prolines is not essential. ... 

Primary pump drive pony motors will normally not be used during an outage however, some units may be placed on electric drives to conserve steam Automatic actuation will normally be effective if the loop la on recirculation since drive unit speeds will be in excess of 900 rpm Shortly after a nuclear shutdown residual heat generation rates will be low and the emergency raw water system may be bypassed and moved from service to minimise the chance of raw water Introduction Into the primary system. Manual actuation will provide backup If normal cooling la lost and fuel overheating la approached.
