Impedance Response and Dielectric Relaxation in Liquid-Phase Sintered Zn2SnO4-SnO2 Ceramics
(Springer, New York, 2010)
Impedance/admittance and dielectric spectroscopy were used to investigate the effect of temperature on the electrical response of liquid-phase sintered Zn2SnO4-SnO2 ceramics. The measurements were performed over a wide ...
Influence of Rare-Earth Dopants on Barium Titanate Ceramics Microstructure and Corresponding Electrical Properties
(Wiley-Blackwell Publishing, Inc, Malden, 2010)
In this article, ytterbium and erbium oxides are used as doping materials for barium titanate (BaTiO(3)) materials. The amphoteric behavior of these rare-earth ions leads to the increase of dielectric permittivity and ...
In vitro pollen germination and pollen grain morphology in some sweet cherry (Prunus avium L.) cultivars
(Romanian Biotechnological Letters, 2013)
In vitro pollen germination on agarose-sucrose medium, and pollen grain morphology by scanning electron microscopy, were investigated in four sweet cherry (Prunus avium L.) cultivars ('Karina', 'Kordia', 'Regina' and ...
Isoenzyme Polymorphism in Apricot Cultivars
(Amer Pomological Soc, University Pk, 2009)
Eighteen enzyme systems were studied in 50 apricot (Prunus armeniaca L.) cultivars of diverse geographical origin using polyacrylamide gel electrophoresis. Thirteen systems were polymorphic at 20 loci. This polymorphism ...
Collection and detection of eriophyoid mites
(Springer, Dordrecht, 2010)
Methods for collecting and detecting eriophyoid mites are crucial components in research, taxonomical and biological studies, and control programs for these organisms. Their small size, their specific host-plant interactions ...
Improving the chemical properties of acid soils and chemical composition and yield of spring barley (hordeum vulgare l.) By use of metallurgical slag

Seasonal water pricing using meteorological data: case study of Belgrade
(Elsevier Sci Ltd, Oxford, 2013)
The paper presents a model of seasonal water pricing (SWP) aimed primarily at diminishing excessive fresh water use in the city of Belgrade. Seasonal prices are determined on meteorological observations of the average ...
Weight and egg quality correlation relationship on different age laying hens
(Journal of Food, Agriculture and Environment, 2010)
With the aim to determine the influence of Lohman Brown laying hen hybrids age and eggs weight on some characteristics of eggs quality-structure and their correlation relationship, experiment was conducted on two egg samples ...
