A 25-mL, single-necked, round-bottom flask is equipped with a Teflon-coated stirring bar, a reflux condenser, and a gas inlet tube. NBC (0.156 g, 0.508 mmol), absolute ethanol (10 mL), triethylamine (0.50 mL, 3.6 mmol), and 2-bro-moacetamide (0.239 g, 1.73 mmol) are added to the flask, and the reaction mixture is refluxed under a N2 atmosphere for 3 h. The product precipitates during the course of the reaction and after cooling is filtered and washed

The U.S. NBAC, CIOMS, and WMA all say that therapeutic studies should benefit the community where the research is done in exchange for their cooperation and to avoid exploitation. Affable advice such as "Clinical trials conducted in developing countries should be limited to those studies that are responsive to the health needs of the host country" (NBAC 2001) is insufficient to redirect First World researchers to priorities, products, or benefit sharing that benefits developing countries where First World research is conducted (Kass and Hyder 2001 NBAC 2001 Kass, Dawson, and Loyo-Berrios 2003). 

Some propose a duty to equitably share intellectual rights (UNDP 2001). The KFPE says, "Research results have intellectual worth and may also have a commercial value. All partners should share equally in the benefits of both" (SCRP/KFPE1998). Brazil says that research with human subjects "must ensure the research subjects the benefits resulting from the research project, in terms of social returns, access to procedures, products or research agents" (NBAC 2001 57).

The AZT trials triggered the revision and elaboration of documents such as the Declaration of Helsinki, the CIOMS-WHO Guidelines, a new report of the NBAC of the U.S. The battlefields of the standard of treatment debate were research ethical codes. The revision of the Declaration of Helsinki (WMA 2000) at the end of the 1990s is an... 

There are a number of large specimen banks and repositories in the United States, administered primarily by federal government. Others are administered by the military, universities, corporations, and nonprofit organizations (NBAC 1999). Similarly, the EU has specimen banks available for research purposes. A few examples from in the United States and EU are described below.

A listing of the principal metallic carbides was provided in 17.3.9 (Fig. 1), along with the most common stoichiometric compositions (Table 1). Metallic carbides are stable over wide composition ranges, which do not necessarily encompass the ideal stoichiometry. For example, TiC is encountered in the range 0.28 < x < 1 VC is stable in the range VC, 0.75 < x < 0.96, which does not include the stoichiometric composition NbaC is stable as NbC, with 0.35 < x < 0.5 TaC also exists only off-stoichiometry. Such wide compositional variations arise from the small size of the C atom, which can readily fit into interstices between metal atoms in the lattice these sites may be filled to widely different degrees.
