Experience and conditioning indicate media have strengths in this role, but sources must have a good track record on these occasions. Media are relinquishing control under prearranged plans for such communications. 

Indicator media when a certain indicator (nentral red or bromothymol blue) or reducing agent (potassium tellurite) is incorporate into the cnlture medium it is called an indicator medinm. The colonr of the medinm changes with alterations of pH due to bacterial growth. 

Cell Growth and DNA Manipulation DNA manipulations were performed according to standard protocols [12]. A glucose-tolerant strain of Synechocystis sp. PCC 6803 [13] was grown as previously described [3], except that glucose (5 mM) was included in all media, unless otherwise noted. Where indicated, media were supplemented with 2.5 pg chloramphenicol (Cm) per ml, 0.1 pg erythromycin (Em) per ml, 5 pg kanamycin (Km) per ml, or 20 pg spectinomycin (Sm) per ml. Extraction of chromosomal DNA from Synechocystis was performed essentially as described in [13]. 

However, the suitability of indirect indices is established by both animal experimental and human epidemiological studies. Such indicator media are blood, urine, feces, and hair, which have in common their easy availability.

The relationship of levels of heme intermediates in biological indicator media appears to be a complex one with respect to 6-ALAD genetic polymorphism. For plasma and urinary 6-ALA versus genotype, results from various studies do not allow conclusions, in part because of sample sizes and in part because of the range of exposures indexed as PbB from low, environmental exposures to the higher exposures seen in workers. A general... 

Basically, the very same media can be used for solid fermentation-indicator media in plates for replica plating. Reliable results can be obtained only under certain conditions since change in color is due to acid formation, and some strains produce acid even on glycerol medium, simulating fermentation otherwise absent on this medium the rate of ferementation has to be fairly high, so that the acids formed are not used again. Therefore, solid fermentation-indicator media should be used only if the results thus obtained have been shown to be the same as with the fermentation tube assay. 

Fig. 2 Effects of media and serum on the differentiation assay. Differentiation was quantified after the indicated media were used from day 10 of differentiation, the stage when cardiomyocytes form. The use of semm at indicated concentrations suppresses cardiac differentiation compared to StemPro medium. In contrast, use of a range of KOSR containing media or a serum free medium increased differentiation over the level observed StemPro medium...

Strong conformational dependence (SCD). These groups have the structures (a) MZ2 Z and MZ Z Z , where the superscript M indicates medium, (b) Planar jt-bonded groups MZ Z where M and either or both Zs are sp hybridized, such as phenyl, acetyl, nitro (Xpjt groups), (c) Quasi-planar jr-bonded groups such as dimethylamino and cyclopropyl. 

Vanadium concentrations in blood, serum or urine are used as a biological indicator of exposure to vanadium. Urine and serum are the specimens with widest application and greatest practicability for monitoring human exposure to vanadium compounds, but urine is preferred as an indicator medium. Blood vanadium appears to be a less sensitive indicator than urinary vanadium, partly because the differences in concentrations are hardly appreciable at low levels of exposure with the analytical methods available (Alessio et al., 1988). 

Differential media these distinguish colonies of specific microbes from others. When a culture medium containing certain substances helps to distinguish the differing properties of different bacteria, it is called differential media, e.g., MacConkey agar. It is also an indicator medium. It contains peptone, agar, lactose, sodium taurocholate and nentral red. The lactose fermenters form pink colonies while non-lactose fermenters produce colourless or pale colonies. Blood agar it serves both as an enriched as well as an indicator medium and shows different types of haemolysis. 

While Muramatsu and Parr [%] found a highly significant correlation of mercury in hair and in the renal cortex. Blinder et al. [21] concluded that hair is not a suitable indicator medium for monitoring exposure to inorganic mercury. 

The biological monitoring of lead exposure in paediatric and adult human populations has usually involved one of two approaches (1) measurement of the internal or systemic dose of lead itself in some indicator medium, or (2) quantification of some subcritical effect of lead. The extent to which biological monitoring in humans accurately states both exposure risk and relative health risk remains the subject of much research. Of particular interest are (1) the biokinetic characteristics of the common indicators of exposure, (2) the development and use of kinetic models of lead metabolism, and (3) the relative merits of the use of biological effect indicators versus measurement of the toxicant in some medium. 

Figure 1 Heatmaj of the confidence scores, by voting member, sorted by the median value. Red and orange indicate high diibiosity, yeiiow indicates medium values and shades of blue indicate high confidence scores gray indicates absence of score. The heatmap is sorted by the median score on the verticai axis and by the research area of the CSG experts on the horizontal axis. The first two coiumns refiect pharmacokinetics and toxicology, the last four columns reflect a chemical/ HTS perspective and the middie five coiumns are based on cheminformatics tools and experience. Table 1 describes the distribution of scores.

In this example it would therefore be justifiable to spend up to 22 million on appraisal activity which would distinguish between the high, medium, and low STOMP cases. If it would cost more than 22 million to determine this, then it would be better to go ahead without the appraisal. The decision tree has therefore been used to place a value on the appraisal activity, and to indicate when it is no longer worthwhile to appraise. 

The method was applied for determination of the quality of the detection media on test pieces following the type testing of the European standard [4] in order to check the validity of the method. The other application was the determination of the visibility in dependance of the variations of the inspection parameters (application of the detection medium, magnetization, inclination, viewing conditions) in a range which may appear in the practical inspections. The results leads to conclusions on the visibility level which is a measure of the probability of recognition for the indication that means of the reliability of the method. 

Following the draft european standard [4] for type testing, quality of the detection media shall be verified on 2 reference blocks as shown in Fig. 2. On the reference block No. 1, created by Mr. Dickhaut [7], (Nr. 3 of the MTU) the indications shall be valuated by comparison with the indications of a detection medium with known quality. On reference block No. 2 (AFNOR-C A-C) the lenght of the indications shall be determined as a measure for the quality. 

In order to check the the validity of this method [8], 6 detection media Px where selected and applied on the reference pieces following the instructions of the standard (inclination angle 45° 3 applications of the detection medium and averaging). The arrangements of the cuts can be seen at Fig. 3. Indications or parts of indications are chosen for the valuation and marked by dashed lines.
