Recent Trends in Archaeological Theory: Some Comments

 This paper selectively reviews some recent themes in archaeological theory:  a philosophical pragmatism, a turn to materiality, and understanding the past in the context of the present.  It concludes with some reflective comments on the author’s Archaeological Theory:  An Introduction, in advance of the third revised edition.

Recent trends and developments in pyrolysis-gas chromatography.

Pyrolysis-gas chromatography (Py-GC) has become well established as a simple, quick and reliable analytical technique for a range of applications including the analysis of polymeric materials. Recent developments in Py-GC technology and instrumentation include laser pyrolysis and non-discriminating pyrolysis. Progress has also been made in the detection of low-level polymer additives with the u...

Recent and future trends in synthetic greenhouse gas radiative forcing

Atmospheric measurements show that emissions of hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons are now the primary drivers of the positive growth in synthetic greenhouse gas (SGHG) radiative forcing. We infer recent SGHG emissions and examine the impact of future emissions scenarios, with a particular focus on proposals to reduce HFC use under the Montreal Protocol. If these proposals a...

Low Pressure - Gas Chromatography : Recent Trends and Developments

25 Low pressure-gas chromatography (LP-GC) has been applied during the last few 26 years for the fast analysis of various pollutants in different environmental and food matrices. 27 A typical LP-GC setup involves the use of a short microbore column (typically 0.5-1 m x 28 0.10 mm internal diameter) at the injector side connected with a zero dead-volume connector 29 to a short megabore column (t...
