Leek growth and productivity in response to light interception and nitrogen nutrition
(Int Soc Horticultural Science, Leuven 1, 2004)
The aim of this project was to investigate the effect of nitrogen supply and light interception on productivity and growth,of leek (Allium porrum L.). A field experiment, with leek hybrid Alita (Royal Sluis, The Netherlands), ...
The effect of partial root drying on growth, quality of fruits and ions content on tomato (lycopersicon esculentum l.)
(Springer Heidelberg, Heidelberg, 2004)
Calorimetric study of room temperature adsorption of N2O and CO on Cu(II)-exchanged ZSM5 zeolites
(Elsevier, Amsterdam, 2004)
Copper ion-exchanged ZSM5 zeolites have been prepared with different cooper loadings from under- to over-exchanged levels. The adsorptions of N2O and CO at 303 K have been studied using calorimetric method and infrared ...
An analytical approach to the uniqueness problem of hot-wire probes to measure simultaneously three velocity components
(IOP Publishing Ltd, Bristol, 2004)
The uniqueness range of hot-wire probes to simultaneously measure all three velocity components is analysed analytically. Expressions defining the uniqueness cone half-angle are presented for triple as well as for quadruple ...
Nectar production in three melliferous species of Lamiaceae in natural and experimental conditions
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2004)
The nectar production of Lamium maculatum, Lamiastrum galeobdolon and Ajuga reptans was evaluated by determining the Index of nectar production (INP), total nectar quantity per flower during 24h, nectar sugar concentration, ...
Characterization and PCR-based typing of Xanthomonas campestris pv. vesicatoria from peppers and tomatoes in Serbia
(Springer, Dordrecht, 2004)
During the last two decades bacterial strains associated with necrotic leaf spots of pepper and tomato fruit spots were collected in Serbia. Twenty-eight strains isolated from pepper and six from tomato were characterized. ...
DPR analysis of microstructural evolution of ZnO ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
It is well known that, due to their specific properties, ZnO - based materials are frequently used in electrotechnics and electronics. Since these properties are very Much dependent on the microstructural state of material ...
Specific process models derived from extremely small data sets and general process models
(2004 Seventh Seminar on Neural Network Applications in Elecrtical Engineering, NEUREL 2004, 2004)
Definition of a needed particular process model is based on a combination of weighted known general process models and standard error minimization. The known general process models correspond to the biological processes ...
The effect of reversing current on the properties of copper and electrolytic copper powder. I. The morphology of powder particles
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The selective dissolution of copper dendrites during electrodeposition by reversing current was discussed and the effects on the morphology of copper powder particles were elucidated.
Effect of N deficiency on leaf growth and cell wall peroxidase activity in contrasting maize genotypes
(Springer, Dordrecht, 2004)
Two maize genotypes differing in leaf elongation rate (high-LER and low-LER) were used for the investigation of the effects of nitrogen deficiency on leaf growth and development and activity of enzyme cell wall peroxidase ...
