This study provided necessary information toward the chemical identification of the sex pheromone of P lata, which can then be used to monitor its population in relation to that of P. borealis, or as a means to control the cockroach itself, as it is an occasional indoor pest. We have carried out a similar study with Caudell s wood cockroach, Parcoblatta caudelli Hebard, and have demonstrated that in this species calling also is associated with pheromone release and that the sex pheromone is produced in tergites 1-7 (Gemeno et al, 2003b). 

Historically, y-quinacridone has been the first nucleating agent used. Its activity at lowest concentrations made it extremely attractive. However, alternatives had to be found since the induced red coloration was penalizing for numerous applications. Fujiyama has used quinacridonequinone [21], which gave a slight yellow coloration Borealis has developed its colorless nucleating agents [19] as well as Atofina [25] or New Japan Chemicals with the commercial N,N-dicyclohexyl-2,6-naphthalene dicarboxamide (e.g. NU-100) [17]. 

Onchidal is a toxic component of a certain poisonous marine opisthobranch mollusc. Like other opisthobranchs, the Onchidiacea family of molluscs does not have the protection of a hard external shell as do most molluscs. They rely instead on the production of a defensive secretion. When the animal is disturbed it secretes a viscous fluid from specialized glands. In two species of Onchidella Onchidella Jhr-idanun and Onchidella borealis), this defensive secretion has been shown to act as a deterrent to potential predators, including fish and crabs. Chemically, it is a simple lipophilic acetate ester (see Figure 11.1). 

Within the past five years, commercial interest in metallocene catalyst components for the polymerization of olefins has increased enormously. Commercial production of a rising number of polyolefin types from different companies is creating a burgeoning and highly diversified demand for metallocenes. New brand names (e. g., Metocene (Basell), Elite (Dow Chemical), Engage (DuPont), Exact (ExxonMobil), Luflexen (Basell), Apel (Mitsui Chemicals), Borecene (Borealis), Finathene (TotalFinaElf), Topas (Ticona), just to name a few) characterize polyolefins such as PE, elastomers, PP, cycloolefin copolymers (COCs) and PS from metallocene-type catalysts [1-3].

Numerous plasmas exist very far from the thermodynamic equilibrium and are characterized by multiple different temperatures related to different plasma particles and different degrees of freedom. It is the electron temperature that often significantly exceeds that of heavy particles (7 > To). Ionization and chemical processes in such non-equilibrium plasmas are directly determined by electron temperature and, therefore, are not so sensitive to thermal processes and temperature of the gas. The non-equilibrium plasma of this kind is usually called non-thermal plasma. An example of non-thermal plasmas in nature is the aurora borealis (Fig. 1-2).

Borealis has started up its metallocene-based slurry loop polyethylene (PE) plant at Ruenningen, Norway. Borealis will produce 30,000 t/yr of metallocene-based products at the plant in 1997. Borealis has agreed a licensing deal with Exxon Chemical which should avoid future patent conflicts over the companies respective metallocene technologies. In 1996...
