1. History of gibberellin research in the U.K. and personal reflections.

In this memoir, the author recalls the history of gibberellin research in the UK. The study of gibberellin research in the UK began in the early 1950s at the Imperial Chemical Industries (ICI) laboratories at Frythe, an old country house some 25 miles north of London. It all started when Dr. A. W....

2. Proton transfer reaction mass spectrometry, a tool for on-line monitoring of acrylamide formation in the headspace of Maillard reaction systems and processed food.

The formation of acrylamide was measured in real time during thermal treatment (120-170 °C) of potato as well as in Maillard model systems composed of asparagine and reducing sugars, such as fructose and glucose. This was achieved by on-line monitoring of acrylamide released into the headspace of...

3. An improved method to measure spatial variation in root respiration: application to the taproot of a young peach tree Prunus persica.

This paper presents an improved method to measure local root respiration, by suspending roots in a gel that could be sampled using an oxygen microelectrode. The effect of gel type on the oxygen diffusion and on transport of oxygen from the shoot to the root was studied. Local root respiration rates ...

15. Preparation and characterisation of gels based on sucrose modified with glycidyl methacrylate.

Sugar-based hydrogels were prepared by non-selective modification of sucrose with the introduction of vinyl groups. Sucrose was reacted with glycidyl methacrylate (1:1 molar ratio) in DMSO and in the presence of 4-(N,N-dimethylamino)pyridine (4-DMAP) as catalyst. The structure of the product...

16. Influence of the carbohydrate composition on the molecular weight distribution of kraft pulps.

The molecular weight distribution (MWD) of hardwood kraft pulps and softwood kraft pulps dissolved in lithium chloride/N,N-dimethylacetamide (LiCl/DMAc) have a different shape. Two fairly well separated distributions of hardwood kraft pulps are obtained by size exclusion chromatography whereas the...
