Initiative, communication

In this short initial communication we wish to describe a general purpose continuous-flow stirred-tank reactor (CSTR) system which incorporates a digital computer for supervisory control purposes and which has been constructed for use with radical and other polymerization processes. The performance of the system has been tested by attempting to control the MWD of the product from free-radically initiated solution polymerizations of methyl methacrylate (MMA) using oscillatory feed-forward control strategies for the reagent feeds. This reaction has been selected for study because of the ease of experimentation which it affords and because the theoretical aspects of the control of MWD in radical polymerizations has attracted much attention in the scientific literature.

The interaction of dioxygen has been observed in several systems, mostly due to autooxidation of ferrous hemes with dioxygen, but only characterized in a few instances. Sakamoto et al. (119) have illustrated peroxidase-type activity using a helix-disulfide-helix system that binds a single heme as shown in Fig. 13. The initial communication illustrated that the addition of an organic cosolvent, trifiuoroethanol, increases the helical content of the peptide, the affinity for heme (1.7 DM IQ at maximal affinity, 15% TFE), and the peroxidase activity (conversion of... 

Note that in all of the compounds (161, 169, 171, 173, 175) reported in the initial communication in this area, the endo-polyhedral iridium vertex was erroneously assigned as being rhenium whilst the exo-polyhedral Re(CO)3 fragment in complexes 161,169, and 175 was wrongly identified as Ir(CO)3. The assignments herein are correct. 

Since our initial communication (10) concerning the catalytic reduction of organic substrates by this homogeneous hydrogenation system, two further reports have come to our attention de Vries (2) demonstrated the reduction of sorbic acid to 2-hexenoic acid and Kang (8) described the reductive amination of a-keto acids. 

Caliper and gamma ray logs were run to detect caving and borehole irregularities and to correlate the oil shale formations. Airflow tests were made to measure initial communication between injection well 6 and the remaining wells in the pattern. 

Corey and Kim first described the use of NCS and DMS for the conversion of 1,2-diols into a-hydroxyketones in 1974, two years after their initial communication and gave the... 

Our second break came on June 30, 1999 when we were filling in a Table on the scope of the dimerization reaction for our initial communication on the subject. It was a rookie mistake - Jason Lagona set up the dimerization reaction of 17 below reflux and without the azeotropic removal of H2O. Luckily, Jason handled the outcome like a seasoned veteran and isolated 17, Civ-WC, and a new compound. This new compound turned out to be the S-shaped compound (C2/1-IIS) that we had been searching for The stereochemical assignment was... 

Sensation is but one part of communication. In order to be complete, communication is sensation that invites response, and that, in turn, may elicit an additional response from the original initiator. Communication can take one of four forms (Nelson et al., 1970) ...

An increasingly important class of system software is communication software. Communication software provides mechanisms for processes on different computers to communicate. Initially, communication software was included in operating systems. Today, it is being increasingly packages as middleware. Middleware provides facilities for processes on different computers to communicate as well as other facilities for finding and sharing... 

Pentaphenylarsenic has been found to be isomorphous with penta-phenylphosphorus 419) although different from pentaphenylantimony which has the unusual square pyramidal arrangement of ligands. The initial communication suggested that the phosphorus and arsenic compounds also have a square pyramidal structure, however, since penta-phenylphosphorus has now been found to have the trigonal bipyramid structure 420) it can be expected that this arrangement also exists in pentaphenylarsenic. 

Communication systems are categorized as on-site TA-V and off-site TA-V. The on-site systems consist of the TA-V intercommunications system, TA-V paging system, telephones, and the TA-V Evaluation Team radio net. The off-site system consists of telephones and the SNL/NM radio-communications network. Initial communications with SNL/NM groups outside TA-V and the KAFB Fire Department are coordinated by the TA-V EMSUP and the external communicator. 

Subsequent to Buchwald s initial communication in 1998, a number of other groups have developed related variants of bulky, electron-rich aryldialkylphosphine ligands for Suzuki (and related) cross-couplings of aryl chlorides [42]. Beller and coworkers have developed readily synthesized and tunable N-aryl-2-(dialkylphosp hino) imidazole and -benzimidazole as ligands for paUadiumSuzuki couplings of aryl chlorides (Equation 2.24), and a number of these are now available commercially [43],...
