Homology to immunoglobulin units is also found in molecules which are not directly involved in immune recognition. Whilst some of these molecules have no known function (Thy-1, MRC OX-2, a, B-glycoprotein), others clearly interact with homologous molecules either within the immune system (immunoglobulin receptors) or in different systems (NCAM and MAG/Ncp 3). 

Homology to immunoglobulin units is often weak whilst /3-strand patterns are suggestive of V units, only Thy-1. the membrane-distal unit of MRC OX-2 and the poly-immunoglobulin receptor units possess the extra hairpin loop (C /C ) which is characteristic of V units (Fig. 11). Thus, the polypeptide chain may fold in a similar way to C units. Although all these molecules are believed to exist as monomers, in most cases the possibility of homodimeric associations has not been ex-

Where a Member State ascertains tliat a product, bearing the CE-marking and used in accordance with its intended use, is liable to endanger the safety of persons or health, it shall take all appropriate measures to withdraw such a product from the market. That Member State shall immediately Inform the Commission which is obliged to investigate whether or not the measure is justified. Where the Commission considers that the measure is justified, it shall immediately inform the Member State which took the initiative and also the other Member States. This entails that the other Member States must also take action against the product concerned. That latter disposition is referred to as the safeguard clause. 

The recognised third party organisations can be notified by the Member States to the Commission and the other Member States for the earrying out of approvals related to the qualification of personnel and procedures for permanent joining and for the qualification of personnel for non-destructive testing. 

Boron, being chemically a non-metal, is resistant to attack by nonoxidising acids but the other members of the group react as typical metals and evolve hydrogen. Aluminium, gallium and indium are oxidised to the + 3 oxidation state, the simplified equation being... 

One speeial member of the group, when eombined with any other member of the group, must leave the group member unehanged (i.e., the group eontains an identity element). 

Note that the characters of both rotations are the same as are those of all three reflections. Collections of operations having identical characters are called classes. Each operation in a class of operations has the same character as other members of the class. 

Lithium is presently being recovered from brines of Searles Lake, in California, and from those in Nevada. Large deposits of quadramene are found in North Carolina. The metal is produced electrolytically from the fused chloride. Lithium is silvery in appearance, much like Na and K, other members of the alkali metal series. It reacts with water, but not as vigorously as sodium. Lithium imparts a beautiful crimson color to a flame, but when the metal burns strongly, the flame is a dazzling white. 

A member of the platinum group, ruthenium occurs native with other members of the group in ores found in the Ural mountains and in North and South America. It is also found along with other platinum metals in small but commercial quantities in pentlandite of the Sudbury, Ontario, nickel-mining region, and in pyroxinite deposits of South Africa. 

Various species of carp and other members of the family Cjprinidae lead the world in terms of quantity of animals produced. In 1992 the total was... 

For the most part, the chemistry of gold is more closely related to that of its horizontal neighbors ia the Periodic Table, platinum and mercury, than to the other members of its subgroup, copper and silver. Comprehensive treatments of gold chemistry can be found ia the Hterature (see General References). 

Helium, plentiful in the cosmos, is a product of the nuclear fusion reactions that are the prime source of stellar energy. The other members of the hehum-group gases are thought to have been created like other heavier elements by further nuclear condensation reactions occurring at the extreme temperatures and densities found deep within stars and in supernovas. 

Unlike aniracetam, pramiracetam does not appear to interact with dopaminergic, serotonergic, or adrenergic neurotransmission (72). The agent inhibits prolylendopeptidase in certain brain areas, but its inhibition constant, iC, is only 11 ]lM (69). The absence or weak activity of this compound with various neuronal systems appears to make it less likely to be of significant therapeutic value than other members of this class of agents. 

Fortimicins B and KE show only weak antibacterial activity, and C is somewhat less active than A or D. Other members of the fortimicin complex are described in the Hterature (198,199). Two closely related naturally occurring complexes, the istamycins, istamycin A [72503-79-8] is... 

Polysulfide Melt. Cl Sulfur Black 1 [1326-82-5] (Cl 53185), derived from 2,4-dinitrophenol, is the most important dye in this group which also includes the indophenol-type intermediates. The latter are appHed in the stable leuco form. The derived dyes are usually confined to violet, blue, and green shades. Other members of this group are intermediates capable of forming quinoneimine (10) or phenazone stmctures (11) that produce red-brown or Bordeaux shades ... 

Many related complexes, such as the platenomycin complex (initially YL-704) from S. platensis suhsp. malvinus have been obtained (201—206). A series designated by abbreviations (DHP, DOA) was obtained from another strain of S. platensis (207) the midecamycin complex (initially SF-837) was produced by S. mjcarojaciens (208—212) the espinomycin factors were produced by S. Jungicidicus var. espinomjceticus (213,214) the turimycin series of fifteen components, isolated from culture broths of S. hjgroscopicus are identical to other members of the leucomycin group (215). Niddamycin (42, R = H, R = butyryl) was isolated from cultures of S. djakartensis (216).

Another method of estimating autoignition temperatures is to compare values for a compound with other members of its homologous series on a plot vs. carbon number as the temperature decreases and carbon number increases. Affens gives a formal procedure for such estimation. 

Other members of the medium-alloy group are Incoloy 825 and Hastelloy G-3 and G-30. Wrought Incoloy 825 has 40 percent Ni, 21 percent Cr, 3 percent Mo, and 2.25 percent Cu. Hastelloy G-3 contains 44 percent Ni, 22 percent Cr, 6.5 percent Mo, and 0.05 percent C maximum.
