Selection procedure questions concerning

This poses a question concerning deacidification. If a deacidification procedure does not remove aluminum from the cellulose carboxyls, will the paper have the stability that one would expect from a paper with an alkaline filler In an attempt to answer this question, a series of hand-sheets was made from a hardwood kraft pulp. This pulp was selected because (a) it had a carboxyl content of 5.75 mmol/100 g pulp, which is similar to that of some old papers (b) it was easy to beat in a laboratory beater and (c) the physical properties of the handsheets were in the "old... 

DCC presents several basic requirements in addition to the selection of a satisfactory set of components, i) a major task in the development of VCLs is the search for suitable reversible processes to connect them ii) it is desirable to devise procedures for quenching these processes so as to lock-in irreversibly the constituent(s) expressed Hi) library deconvolution methods for the rapid identification of the components contained in the active constitu-ent(s) are needed finally, practical, but not minor, questions concern the characterization of the constituent of the VCL that is being expressed. 

Pesticides used on crops grown on the test site in previous seasons may also have an impact on the outcome of a field residue trial. Carryover of prior pesticide applications could contaminate samples in a new trial, complicate the growth of the crop in a trial, or cause interference with procedures in the analytical laboratory. For this reason, an accurate history of what has transpired at the potential test site must be obtained before the trial is actually installed. The protocol should identify any chemicals of concern. If questions arise when the history is obtained, they should be reviewed with the Study Director prior to proceeding with the test site. In most annual crop trials, this will not be a significant issue owing to crop rotations in the normal production practices, because the use of short residual pesticides and different chemical classes is often required for each respective crop in the rotation. However, in many perennial crops (tree, vines, alfalfa, etc.) and monoculture row crops (cotton, sugarcane, etc.), the crop pesticide history will play a significant role in trial site selection.
