(Carfax Publishing, Basingstoke, 2001)
Restructuring the monopolistic, state-owned, obsolete and polluting utility industries of post-socialist economies poses a challenge for the utility deregulation wave travelling around the world. Utility restructuring in ...
Fruit set and fruit quality at different crossings between sour cherry cultivars
(Acta Horticulturae, 2000)
By diallelic reciprocal crossings and open pollination of sour cherry cultivars 'Meteor', 'Oblacinska' and 'Heimanns Konserven', pollination effect (based on fruit set and fruit harvested) and fruit quality (based on fruit ...
Immobilization/encapsulation of cells using electrostatic droplet generation - Experiments and theory
(Edizioni Minerva Medica, Turin, 2000)
The mechanism of alginate droplet formation as well as experimental parameters for producing very small polymer microbeads (i,e, less then 100 microns diameter) using an electrostatic droplet generator were investigated, ...
The preferred orientation of bright copper deposits
(Trans Tech Publications Ltd, Durnten-Zurich, 2000)
The preferred orientations of copper deposits obtained from acid sulfate solutions were examined. Mat deposits obtained in the absence of the additives and in the presence of disodium 2-naphthol-3,6-disulfonic acid possessed ...
