J. J. Sakuraitions to linear molecules thus have to be regarded as highly preliminary. Weak IR-features were found at the positions at which aromatic carbon ring molecules should absorb; otherwise no striking coincidences with interstellar IR-features were noticed.

G. C. Wickable evidence indicates that PCBs are weak genotoxicants and initiators of carcinogenesis. However, at levels above a threshold, PCBs are potent promoters of hepatic carcinogenesis in laboratory rodents. While PCBs are able to enhance the biological generation of genotoxic metabolites of many carcin

Elliot Leadernt electrical properties. High-value load resistors for static random-access-memory (RAM) cells utilize the high resistance of lightly doped polysilicon to provide a convenient and stable resistor that limits the current flowing in the cell. The excellent technological compatibility of polysilicon w

Michel Gourdines. These shifts are constant and from them an order number . or .. for each member in the annellation series may be derived. In striking contrast to this, very different spectral shifts are produced by the successive connection of two diphenyl systems to benzene (I) forming triphenylene (II) and te
