L 2 aminobutyric acid can substitute for L-alanine (CyV). N-Methyl-L-leucine in position 4 may be replaced by N-methyl-L isoleucine (Cy29) or by L-valine in CyQ and CyS. Regarding possible biosynthetic pathways, variations at position 1 are of special interest CyF and CyK contain deoxy-MeBmt, whereas N-methyl-L-Z-amino-octanoic acid is found in CyZ, Both building units probably stem from a common precursor of the genuine amino acid (4R) 4 l E) 2 butenyI] 4 fnethYl L-threonine (Bmt). A full exchange of this characteristic structural unit by N-methyl-L-leucine is observed in CyO. At present, positions 3 and 8 containing sarcosine and D-alanine, respectively, are the only conserved building units. 

The licensing and supervision of nuclear installations in Germany is the responsibility of the Federal States (Lander) who are subject of expediency supervision of the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB). 

In Sec. 3, some recent developments of structure conserving integrators will be reviewed. Such symplectic or symmetric integrators are build to preserve certain geometric properties of the exact QCMD solution like energy... 

Backbone generation is the first step in building a three-dimensional model of the protein. First, it is necessary to find structurally conserved regions (SCR) in the backbone. Next, place them in space with an orientation and conformation best matching those of the template. Single amino acid exchanges are assumed not to affect the tertiary structure. This often results in having sections of the model compound that are unconnected. 

Microscopists in every technical field use the microscope to characterize, compare, and identify a wide variety of substances, eg, protozoa, bacteria, vimses, and plant and animal tissue, as well as minerals, building materials, ceramics, metals, abrasives, pigments, foods, dmgs, explosives, fibers, hairs, and even single atoms. In addition, microscopists help to solve production and process problems, control quaUty, and handle trouble-shooting problems and customer complaints. Microscopists also do basic research in instmmentation, new techniques, specimen preparation, and appHcations of microscopy. The areas of appHcation include forensic trace evidence, contamination analysis, art conservation and authentication, and asbestos control, among others. 

The American Society for Testing Materials (ASTM) recommends 250 ml of solution for every square inch of area of test metal. Exposure time is also critical. Often it is desirable to extrapolate results from short time tests to long service periods. Typically, corrosion is more intense in its early stages (before protective coatings of corrosion products build up). Results obtained from short-term tests tend to overestimate corrosion rates which often results in an overly conservative design. 

Another method is a series of exhaust dilution equations based on Wilson and Lamb " and a series of earlier papers summarized in ASHRAE. This method is based on wind tunnel tests on simplified buildings and is intended to provide conservative (low dilution) results. Wilson and Lamb compared the model to actual field data collected at a university campus and found that the model did indeed predict dilutions similar to measured worst-case dilutions suitable for a screening model. However, many cases resulted in conservative Linderpredictions of dilutions. ...

Chlorofluorocarbon-blown foam blocks are used to insulate the walls and roofs of some buildings, thus reducing heat losses and helping to conserve fossil fuels. In this area, polyurethane foam competes with polystyrene foam, which until recently was blown with dichlorodifluoromethane (CFC 12) but is now blown with a mixture of chlorodifluoromethane (HCFC 22) and 1 -chloro-l,l-difluoroethane (HCFC 142b).
