Comparison of ripening processes in intact tomato fruit and excised pericarp discs
Physiological processes characteristic of ripening in tissues of intact tomato fruit (Lycopersicon esculentum Mill.) were examined in excised pericarp discs. Pericarp discs were prepared from mature-green tomato fruit and ...
Expert system supervisory control of the Wheal Jane tin concentrator
This paper reports computer simulation and modelling techniques used at the Wheal Jane tin mine in Cornwall to improve processing efficiency.
Changes in force and stiffness induced by fatigue and intracellular acidification in frog muscle fibres
1. Changes in force and stiffness were recorded simultaneously during 1 s isometric (fixed ends) tetani of single fibres isolated from the anterior tibialis muscle of Rana temporaria (temperature 1-3 degrees C; sarcomere ...
The water-content water activity relationship of cured tobacco and water relations of associated spoilage fungi
The relationship between moisture content and water activity (aw) in cured tobacco was significantly influenced by sugar content. Overall, high sugar tobaccos such as Oriental and Virginia had a higher moisture content at ...
The effect of (-)-hydroxycitrate on the activity of the low-density-lipoprotein receptor and 3-hydroxy-3-methylglutaryl-CoA reductase levels in the human hepatoma cell line Hep G2
(-)-Hydroxycitrate, a potent inhibitor of ATP citrate-lyase, was tested in Hep G2 cells for effects on cholesterol homoeostasis. After 2.5 h and 18 h incubations with (-)-hydroxycitrate at concentrations of 0.5 mM or higher, ...
Terrestrial and aquatic bryophytes as monitors of environmental contaminants in urban and industrial habitats
The widespread distribution of bryophytes and the tolerance of many species to certain contaminants has led to their use for monitoring purposes. Early this century, changes in the distribution of mosses in urban habitats ...
