Main active

An organisation such as the example above includes sub groups for each of the main activities and a support (or services) group to manage information and procurement. Auditing commitments may be fulfilled by an independent in-house team or by external auditors. 

Due to the many problems concerning steam generators of nuclear power plants over the last decades, we developed our own inspection equipment and services. Next to this main activity, we provide inspections for nuclear power plants components such as thimbles, guide carts and baffle bolts. 

An extension of these calculations to cationic dialkylamide salts required an even more complex model [Adolf et al. 1995]. These molecules have the general formula (CH3)2N [(CH2) iCH3][(CH2)m-iCH3]CK and the isomer with m = m = 18 is one of the main active ingredients in commercial fabric softeners. The presence of two long alkyl... 

Addition of a hydroxyl group to the aromatic ring of ephedrine as well as changing the substitution on nitrogen leads to a compound whose main activity is to raise blood pressure. Thus, lormation of the Shiff base of the m-hydroxy analog of 30 with bcnzylamine (34), followed by catalytic reduction, yields metar- uiiinol (35). When optically active hydroxyketone is employed in... 

When the films were treated in either an oxygen plasma environment or under UV/ozone irradiation, the rates of oxidation were faster for the plasma process. Irradiation of chitosan solution showed that UV/ozone induces depolymerization. In both plasma and UV/ozone reactions, the main active component for surface modification was UV irradiation at a wavelength below 360 nm [231]. 

Although it has been nearly 40 years since THC, the main active psychotropic constituent of the plant Cannabis sativa, was isolated (Gaoni and Mechoulam...

Enzymes most frequently proposed to fruit juices producers are pectinases coming from Aspergillus. Pectinases are exocellular enzymes and are the main activities produced among numerous side activities type hemicellulases, glycosidases. The Table 1 gives the spectrum of enzymatic activities contained in three commercial preparations A, B and C. 

For apple maceration, the main activity is the endopectinlyase (PL) which decreases the viscosity due to the colloidal pectin by decreasing tlie molecular weight of this substrate methylated at about 90%. In association to this PL, exo B and endoarabanase (ARAs), pectinacetylesterase (PAE), rhamnogalacturonase (RG) and other hemicellulases allow to hydrolyse side chains of the pectin, decrease the steric hindrance and make the access of pectinases to the rhamnogalacturonic backbone more easy. 

The yeast strain SCPP exhibits all of the panoply required for the degradation of pectins from various sources. This enzymatic machinery is secreted into the growth medium. Hence, we developped interest on the regulatory mechanisms controlling the synthesis of the main activity produced by the SCPP strain, i.e. the polygalacturonase. 

A serious problem in the early Western medicinal use of C. sativa, mainly as a tincture, was its highly variable activity and inconsistent results. Medicinal preparations have to handle several particularities due to the structure of the active ingredients of C. sativa. The identity of the main active constituent of C. sativa, A9-tetrahydrocannabinol (INN dronabinol) remained unknown until 1964 [128] standardized C. sativa preparations were not available. The plant itself is found in several different chemotypes, which added to the unpredictable nature of early medicinal preparations. 

Last but not least the identification of THC as the main active constituent of C. sativa was preceded by an almost total ban on the plant as a narcotic drug, practically ending medicinal research. 

Figure 1.142 shows the dependence of solubility of Si02 minerals (quartz, cristobalite) on temperature. As described already, cristobalite occurs in peripheral and shallower part of hydrothermal alteration zone. Quartz is present in zones occurring in deeper and closer to the gold-quartz veins. Such zoning from quartz to cristobalite is also common in main active geothermal systems (Hayashi, 1973 Takeno et al., 2000). 

The prophecy on semiochemical systematics in the headline quotation at the start of this chapter remains just that — an intriguing speculation. Some single-component chemosignals do turn up as apparently the main active compound in a complex secretion. In male gerbils (Meriones) one volatile, phenylacetic acid, appears to represent the dominant male state (Thiesen, 1974). Individuality must be added by further components — dietary or variable sebum constituents in this case. Indeed, amongst mammals and some reptiles, complex mixtures seem to be the norm very few taxonomically relevant examples have emerged. 

Marketers are finding a positive role for anti-microbial compounds in areas which have not been seen before. Recent product introductions accompanied by major promotions by Savlon for First Aid-Hand Hygiene Liquid Gel with claims such as kills 99.99% of germs in 15 seconds . The main actives are ethanol, Triclosan and propylene glycol. Another major promotion from Dettol on Anti-septic properties is currently on our television screens, creating a positive image for use of these ingredients, which could only help this industry. 

The AIST was created by the Ministry of International Trade and Industry (MITI) in 1948. Its main activities involve planning industrial S T policies and national R D projects, conducting R D in AIST laboratories, promotion of R D in the private sector, promoting international cooperation and developing national standardization policies. By 1995, AIST had accumulated 10888 patents, from which 1666 were foreign patents. 

It has around 20 staff and research focuses on the following main activities ... 

In the following section, we describe protocols for tests aimed at screening for compounds capable of interfering with some of the main activities of this factor, such as (a) recognition and binding of initiator tRNA (b) codon-dependent ribosomal binding of fMet-tRNA leading to the formation of a 30S or 70S initiation complex (c) ribosome-dependent hydrolysis of GTP and (d) accommodation of fMet-tRNA in the ribosomal P-site and formation of the first peptide bond (initiation dipeptide formation). 

Recrystallization procedure applied to the amorphous aluminosilicates of different chemical composition resulted in the formation of the dispersed zeolitic domains of the FAU and BEA structure in porous matrices. The structural transformation into the composite material was proved with TEM, XRD and 27Al and 29Si MAS NMR spectroscopies. The IR data revealed that strong Bronsted acid centers were main active sites generated in the composite materials, irrespectively of the Al content.
