Use of polsulfone hollow fibers for bubbleless membrane aeration of water
(Environment Protection Engineering, 2000)
Aeration of water with pure oxygen stream was investigated in a bubbleless membrane-based contactor made from 1058 hydrophilic polysulfone hollow fibers. The gauge pressure of 2-4 kPa was maintained in the gas stream in ...
A new procedure of phosphogypsum purification in order to diminish the content of radionuclides
(Hungarian Journal of Industrial Chemistry, 2002)
Phosphogypsum obtained by "wet procedure" for phosphoric acid production is actually calcium-sulphate dihydrate, CaSO 4 ·2H 2 O, which contains a high percent of impurities as well as radionuclides, originating from the ...
Restructuring of the Hungarian electricity industry
(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, ...
Oxidation of CO over Ru containing perovskite type oxides
(Elsevier Science Bv, Amsterdam, 2006)
Perovskite type catalysts La0.7Sr0.3Cr1-xRuxO3 (0.025 lt = x lt = 0.100) were synthesized by annealing a mixture of metal oxides and carbonates gradually up to 1000 degrees C in air, and characterized by XRPD, XPS, TPD, ...
Treatment of Escherichia coli O157:H7 with lactic acid, neutralized electrolyzed oxidizing water and chlorine dioxide followed by growth under sub-optimal conditions of temperature, pH and modified atmosphere
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
The utilization of sub-lethal decontamination treatments gains more and more interest due to the increased consumers' demand for fresh, minimally processed and convenient food products. These products rely on cold chain ...
Boron uptake by the root cortex symplast of tomato and pea plants: evidence for low-boron-induced active transport
(Csiro Publishing, Clayton, 2007)
The objective of this research was to test the hypothesis of the existence of an active boron ( B) uptake into the cortical cells induced by low B supply. The uptake of B was characterised in two tomato ( Lycopersicon ...
Dehydrogenase isoenzyme polymorphism in selected almond genotypes (prunus amygdalus batsch.)
(Bulgarian Journal of Agricultural Science, 2009)
Isoenzyme polymorphism was studied in 20 almond (Prunus amygdalus Batsch.) genotypes, selected in the region of northern Serbia (Vojvodina). Five enzyme systems: alcohol dehydrogenase (ADH), formate dehydrogenase (FDH), ...
RAPD Marker Related to Elongated Fruit Shape in Pepper (Capsicum annuum L.)
(Acta Horticulturae, 2009)
Breeders develop pepper lines with different fruit shapes according to demands of market. It will be useful to develop an efficient tool for identification of fruit shape in pepper seedling. This could shorten a selection ...
