When the deactivation is produced by a chemical, the points to be investigated are :(1) The modifications in the deactivation kinetics, as compared to thermal denaturation, in terms of mechanism, kinetic constants, characteristics of the distribution of intermediate structures; and(2) the extent of the enzyme stabilization by linear-chain polymers, if any... These effects have been shown for a wide variety of different enzymes and of stabilizing polymers as well. However, the results refer to single-step thermal deactivation kinetics :... where N is the native enzyme and D is a totally inactive structure(possibly random coil). Deactivation kinetics other than irreversible first-order are followed quite commonly. Indeed, nonlinear log(activity) versus time curves have been often described in the literature.

CONT

A log is the recording of one physical property of the formation crossed through by a borehole or of the geometric characteristics of the hole or casing or the flow behavior of a well as a function of depth. Wireline logging is performed with a sonde or probe lowered into the borehole or well, usually after the drillstring has been withdrawn.

OBS

Measurements include electrical properties ... sonic properties, active and passive nuclear measurements, dimensional measurements of the wellbore, formation fluid sampling, formation pressure measurement, wireline-conveyed sidewall coring tools, and others. In wireline measurements, the logging tool (or sonde) is lowered into the open wellbore on a multiple conductor, contra-helically armored wireline. Once lowered to the bottom of the interval of interest, the measurements are taken on the way out of the wellbore. This is done in an attempt to maintain tension on the cable (which stretches) as constant as possible for depth correlation purposes ... Most wireline measurements are recorded continuously even though the sonde is moving.

A special radioactivity well log, electronally adjusted to replace the gamma-ray emissions resulting from the collision of neutrons with chlorine atoms in the formations.

Salinity, or chlorine, logs provide an indication of the relative amounts of oil, gas, or salt water in a formation.

A well log of the wall-contact log type that measures radioactivity induced by neutron-neutron reactions. Fast neutrons of several MeV energy, emitted by a source in the sonde, may be slowed and backscattered as epithermal neutrons(0. 4 to 100 ev) by collisions with hydrogen nuclei. Epithermal-neutron abundance is interpreted by assuming a constant lithology, usually limestone, that produces a continuous curve in porosity units. The epithermal-neutron log is largely insensitive to the differences in chlorinity of formation water that may hamper the interpretation of the thermal-neutron log and neutron-gamma log.

for "saw cut veneer" : Veneers are cut in two grades or thicknesses, known as saw cut and knife cut. The first named are the thickest, and vary in thickness from 1/32 to 1/16 of an inch. They are cut from the log with a large circular saw, and usually yield about 12 sheets to the inch. Knife cut veneers are much thinner, modern machines making it possible to get from 50 to 100 sheets to the inch, the very thin ones being used as picture mounts. These are cut with rotary and flat knives. In saw cutting the log is well steamed and placed between two stocks, like a leg in a lathe, and under a knife for its whole length. The log is now forced round and against the knife which drops the required thickness at each revolution. By cutting spirally the grain is accentuated and enlarged.
