in this study, the performance of different cultivation methods on sugar beet fields was evaluated. eight treatments were considered: a) use of a rolling cultivator twice during the growing season; b) use of a rolling cultivator three times during the growing season; c) use of a crescent cultivator twice during the growing season; d) use of a crescent cultivator three times during the growing s...

The effect of crystal size on VHP sugar colour was evaluated on a factory scale over the 1988/89 season at Sezela. Generally, smaller crystals produced lower sugar colour but the difference wasnot significant (at the 5% level) in the size range tested. Smallercrystals producedloweraffinated sugarcolourand the difference was significant at the 5% level. The mass of sugar in a full rail truck was...

objective: many agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. thus agronomic package must be always modified. this sutdy was laid out for evaluation of changes in carbohydrates and sugar yield in sugar beet (beta vulgaris l.) under different biofertilizers and irrigation closed time at dorud region of iran, during 2013. methods: the experimental design...

Steamconditioning (desuperheating) is an essential and critical part of sugar production, particularly with reference to the processing of expressed juice where criticalsteamtemperatures are most necessary to ensurefinal quality. Desuperheating is a simpleprocess that is not widely understood in principle and is much abusedin its practical application and operation. The purposeof this paper is ...

This personal account summarizes our recent developments in gold-catalyzed direct substitutions on propargylic (allylic, benzylic) alcohols, with various nucleophiles (and bi-nucleophiles) based on the σ- and/or π-acidity of gold(III) complexes. Synthetic developments are also briefly described.

Direct allylic etherification of unactivated alcohols occurs regio- and stereoselectively under mild, gold(I)-catalysed conditions.

By 1961 the situation had become reversed. The fibre consumption of the highest income groups relative to that of the lowest increased steadily during this period. When compared to the lowest two social classes the highest two with the higher overall fibre intake emerged with a lower incidence ofCHD over the twenty years.73 Finally, in a prospective secondary prevention study, Daan Kromhout and...
