The theory described here was originally developed by the author, as also the specific targeted application of the theory to molecular modeling of the transition metal complexes. This and other original methods of molecular modeling described here have been implemented in FORTRAN program suits. They are a kind of research software available for use to other researchers through the Net Laboratory access system which provides sample input files and minimal reference information to start with, at http //www.qcc.ru/ netlab. 

In many laboratory information systems, electronic entry either in the laboratory or at a nursing station of a test order for a uniquely identified patient generates a specimen label bearing a unique laboratory accession number. A record is established that remains incomplete until a result (or set of results) is entered into the computer against the accession number. The unique label is affixed to the specimen collection container when the blood is drawn. Proper alignment of the label on the collection container is critical for subsequent specimen processing when using bar coded labels. Arrival of the specimen in the laboratory is recorded by a manual or computerized log-in procedure. In other systems, the specimen is labeled at the patient s bedside with the patient identification and collection information and enters...

Until recently, the hybridization probe has always required radioisotopic labeling (normally with P), particularly if the genome under study was derived from a eukaryote. This placed artificial limits on the number of probes that could be manipulated by any laboratory within a set time period, and had a major impact on staff training, laboratory layout, laboratory access, and management. The recently developed nonradioactive systems (e.g., digoxigenin-labeled probe... 

The unique accession number given to a sample on receipt follows it through the analytical phase to the production of the final report. Machines with bar-code reading capability can read bar-coded laboratory accession numbers and link these with associated reports for these patients via computer interfacing. This allows the production of a cumulative report from which disease trends can be assessed. Bar-coded primary sample tubes (i.e., no aliquoting) can be handled on these analyzers. 

Owing to the high workloads (often 2000 or more samples per day), samples are uniquely identified with a laboratory accession number. If serum or plasma is required, the blood sample is centrifuged (at 3000rpm) and the serum or plasma may be removed but primary tube sampling is now prevalent and a gel separator allows pouring off of the supernatant if desired (see the section Large-capacity analyzers ). 

Studies of the dynamic properties of peptides in the sofid state are not very common. The main reason for this is lack in many laboratories access to NMR instruments dedicated for sofid-state measurements. Moreover, lower resolution of sohd-state spectra sometimes can lead to uncertainty in interpretation of the results. On the other hand, in solution the dynamics is defined mainly by overall tumbling of the molecule. Thus, the site-specific structure variations, and consequently local dynamics, are difficult to observe. In the sohd-state, the overall tumbling of species is not present and insight into the local changes is facifitated and deeper. The important NMR observables such as the dipolar and quadrupolar couplings as well CSA interactions in the condensed matter are not averaged by overall tum-bhng and slow internal dynamics. These parameters, combined with measurements of diflerent relaxation times, provide precise information about local molecular dynamics of peptides. 

It is supposed that Waters offers a new approach with the UNIFI system. The basic idea is that all systems of a laboratory access the same data pool in the database. Here, the single components CDS, ELN, and SDMS can be connected to, which are required by the customer. By using a shared database all connection steps are obsolete, and the single system could cooperate seamlessly. The only question that has not been solved yet is how systems of other suppliers could dock on. In case UNIFI will be kept as a proprietary Waters system, this concept could not be considered as a comprehensive approach for the laboratory of tomorrow. 

Chemicals should be stored safely and securely on the basis of risks and hazards, as outlined in Prudent Practices in the Laboratory. Access to the storage area should be limited to persons approved by the laboratory manager or supervisor and the CSO. The list of authorized persons should be posted at the storage facility and communicated to all laboratory personnel. It is important to maintain an appropriate level of security (for example, door locks, lock boxes) for all chemicals, especially COCs (as discussed earlier). Laboratory managers should remind users that COCs should be secured when not in nse. There should be a requirement that unwanted or unneeded chemicals are returned to the storage area at the end of a project or process. Experience indicates that the CSO needs to reinforce this requirement regularly.
