Wavelength (nm) 1995), analysis of sugar related products (Schaffler et al., 1993) and predicting varietal resistance to the stalk borer Eldana saccharina Walker (Lepidoptera: Pyralidae) (Rutherford et al., 1993). This paper is a summary of some past and current research in South Africa, as well as indicating potential new applications. Comparison of NIR spectra for a range of products tested a...

Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS) has been developed, optimized, and applied to investigate the dimethylsulfide (DMS) emissions from eight marine phytoplankton species, namely, Calcidiscus leptoporus, Emiliania huxleyi, Phaeodactylum tricornutum, Chaetoceros neogracilis, Dunaliella tertiolecta, Synechococcus, Prochlorococcu...

This work presents the heterogeneous kinetics of the reaction of CH 3 SCH 3 (dimethyl sulphide, DMS) with O 3 (ozone) in aqueous solution at different ionic strengths (0, 0.1 and 1.0 M NaCl) using the wetted-wall flowtube (WWFT) technique. Henry's law coefficients of DMS were determined on pure water and on different concentrations of NaCl 5 (0.1 M–4.0 M) in the WWFT from UV spectrophotometric ...

I report on the status of the problem of determining the groups that can occur as the irreducible holonomy of a torsion-free affine connection on some manifold. Résumé. Il s’agit d’un rapport sur le problème de la détermination des groupes qui peuvent être les groupes d’holonomie de connexions affines sans torsion. M.S.C.

Table 1 shows the growth rates of output volume, population and employment in Ireland over various periods since 1926. I take the last period, 1993-2000, as the Celtic Tiger phase. In 1993, total employment was just back to the 1980 level after the large fall in the first half of the 1980s during the worldwide recession following the second oil crisis, and the 1993 level was still 7 percent bel...
