Grain growth during sintering of batio3 with lif
(Taylor & Francis Ltd, Abingdon, 1996)
The sintering behavior of BaTiO3 with LiF showed that it was possible to sinter barium titanate at temperatures below 1000 degrees C. Different combinations of the sintering powders were prepared by adding 1 to 5 w% LiF ...
Genetic, phenotypic variability and correlation analysis in some cabbage cultivars
(Acta Horticulturae, 1997)
The main objectives of this study were: (i) to determine genetic and phenotypic variability and broad-sense heritability for nine morphological characters and (ii) to analyze genetic and phenotypic correlation coefficients ...
Effect of growing method and lettuce fertilization on changes of nitrate content in leaf
(Acta Horticulturae, 1997)
The effect of different amounts of Ca-ammonium nitrates on yield and the accumulation of nitric nitrogen-NO3 was studied in open field and under greenhouse conditions, with special attention for the outer (green) and inner ...
Possibility of nitrogen fixation in Pisum sativum and triticum aestivum
(Acta Horticulturae, 1997)
In order to achieve an accumulation of larger quantities of organic matter in the soil after the growing of peas, the influence of inoculation with azotobacter, nitragine and their mixture, without or combined with nitrogen ...

Fire blight of pear, caused by Erwinia amylovora (Burr.) Winslow, et al., is one of the oldest and the most destructive disease caused by bacteria on pome fruits. This disease is most dangerous on pear (Pyrus sp.), making ...
Genetic analysis of earliness in pepper hybrids (Capsicum Annuum L.)
(Acta Horticulturae, 1997)
We investigated the combining ability, genetic effects and the mode of inheritance of earliness in diallel crossings of 5 divergent pepper genotypes,. The time period from the initial stage of emergence to the initial stage ...
Certain specific electrochemical behaviour of some aldehydes. Potentiodynamic investigations
(Russian Journal of Electrochemistry, 1997)
Two distinct specific features have been clearly observed and recorded by cyclic voltammetry in alkaline aldehyde (typical simple aldehydes and monosaccharides) solutions: (a) Heterogeneous reaction of aldehyde group ...
