Lead azide is not readily dead-pressed, ie, pressed to a point where it can no longer be initiated. However, this condition is somewhat dependent on the output of the mixture used to ignite the lead azide and the degree of confinement of the system. Because lead azide is a nonconductor, it may be mixed with flaked graphite to form a conductive mix for use in low energy electric detonators. A number of different types of lead azide have been prepared to improve its handling characteristics and performance and to decrease sensitivity. In addition to the dextrinated lead azide commonly used in the United States, service lead azide, which contains a minimum of 97% lead azide and no protective colloid, is used in the United Kingdom. Other varieties include colloidal lead azide (3—4 pm), poly(vinyl alcohol)-coated lead azide, and British RE) 1333 and RE) 1343 lead azide which is precipitated in the presence of carboxymethyl cellulose (88—92). 

Soil biodegradation tests were done by taking a sandy loam as the source of the soil micro-organisms. All polymer samples were sieved through ASTM sieves and all the samples except poly-e-caprolactone, had a particle diameter between 90 and 53 pm, Poly-e-caprolactone sample was prepared dissolving a commercially... 

SPME Fiber. A 65 pm poly(dimethylsiloxane)/divinyl benzene (PDMS/DVB) fiber coating (Supelco, Bellefonte, PA) was used in this method. This fiber coating was selected for its ability to retain the derivatizing agent and for its affinity for the PFBOA-aldehyde oxime (7). 

The SPMB fiber was coaled with 65 pm poly(dir tathyi-siloxane)/divinyl benzene (PDMS/DVB SPME).

Cp4 and the secreted segment to the 5 border of the first membrane exon the donor splice site lies within a GGU glycine codon that is retained in ps mRNA. Which form of mRNA is produced depends on competition between splicing and polyadenylation at the p.s and pm poly(A) sites (Peterson and Perry, 1986 Tsurushita et al., 1987 Galli et al., 1988 Peterson and Perry, 1989). The balance between the two mRNA products determines the proportion of membrane and secreted IgM. Activation of the B lymphocyte appears to tip the balance in favor of secretion, but the regulatory signals are not known.

Both films with organic FETs and photodiodes are transferred to the vacuum chamber without exposure to air after the manufacturing process and uniformly coated with a 2 pm poly(monochloro-para-xylylene) (parylene) passivation layer. Spots of parylene on electrodes are removed by a CO2-laser drilling machine for... 

Steric-S-FFF has also been used for numerous fast fractionations including gold, palladium, silver and copper particles in the size range 0.2-15 pm [69,294,385], alumina, low-porosity 7-65 pm poly(vinyl chloride) latex [426] or quartz [427]. Many of these samples were fractionated in times of only 1-5 min. 

Crystallization-induced phase separation can occur for concentrated solutions (gels) of diblocks [58,59]. SAXS/WAXS experiments on short PM-PEO [PM=poly(methylene) i.e. alkyl chain] diblocks revealed that crystallization of PEO occurs at low temperature in sufficiently concentrated gels (>ca. 50% copolymer). This led to a semicrystalline lamellar structure coexisting with the cubic micellar phase which can be supercooled from high temperatures where PEO is molten. These experiments on oligomeric amphiphilic diblocks establish a connection to the crystallization behaviour of related nonionic surfactants. 

Although the activity of purified N. europaea cytochrome c oxidase to catalyze the oxidation of N. europaea ferrocytochrome c-552 is fairly low in vitro, it is much stimulated by addition of poly-L-lysine. For example, one molecule of the oxidase catalyzes the oxidation of nine molecules of ferrocytochrome c-552 per second in 40 mM phosphate buffer, pH 6.0, while the activity is raised up to the oxidation of 64 molecules of the ferrocytochrome c per second on addition of 5 pM poly-L-lysine (Yamazaki et al., 1988). Therefore, poly-L-lysine or similar compounds may occur in the plasma membrane of the bacterium, or some similar microenvironments caused by the presence of poly-L-lysine may occur in vivo.

The chromatographic separations were carried out either on a 15 or 25 cm X 4.6 mm I.D. stainless-steel column packed with 10 pm poly(styrene-dlvlnylbenzene) copolymer (PRP-1, Hamilton). The conventional reverse-phase chromatograpl was performed using either a 10 Pm Whatman PartlsU ODS-3 (25 cm x 4.6 mm I.D.) or a Waters 10 pm pBondapak C,. (30 cm x 3.9 mm I.D.) colimm. The analytical columns were kept at 31° using a column heater (Bioanalytlcal Systems, Inc.,... 

The anthrylpolyamine most effective in binding to heparin (14) was used to follow the activity of heparinase at pH 5. Samples were prepared containing 1 pM probe 14 and 5 pM heparin in 0.1 M pH 5 NaOAc buffer with 0.05 mM EDTA. Under these conditions, the fluorescence of probe 3 is at its minimum as a result of template-directed excimer formation. Addition of heparinase, an enzyme that hydrolyzes heparin to oligosaccharide units (19), results in a flurescence enhancement as shown in Figure 17. One of the most effective polyglutamate binders (13) was used to test the activity of pronase at pH 5. Samples were prepared containing 1 pM probe 13 and 90 pM poly-L-glutamate in 0.1 M pH 5 NaOAc buffer with 0.05 mM EDTA. Under these conditions, the fluorescence of probe 13 is also at its minimum. Addition of pronase, a nonselective proteolytic...
