Aphids (Hemiptera, Aphididae) on ornamental plants in greenhouses in Bulgaria
(Pensoft Publ, Sofia, 2013)
Investigations on the species composition and host range of aphids on ornamental greenhouse plants in Bulgaria was conducted over a period of five years, from 2008 to 2012. Twenty greenhouses, growing ornamentals for ...
ZnTiO3 Ceramic Nanopowder Microstructure Changes During Compaction
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
ZnTiO3 nanopowder as a constitutive component in compact production was primarily characterised. Scanning electron micrographs of as received powder were recorded. Mercury porosimetry and nitrogen adsorption were also ...
The Influence of Compaction Pressure on the Density and Electrical Properties of Cordierite-based Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
Due to its characteristics, cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2), is a high-temperature ceramic material of a great scientific interest. Mechanical activation of the starting mixtures containing 5.00 ...
Fractal Corrections of BaTiO3-ceramic Sintering Parameters
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Morphology of ceramics grains and pores as well as Brownian character of particle dynamics inside ceramics specimen contributes to better understanding of the sintering process. BaTiO3-ceramics, studied in this paper, has ...
Monitoring of aphid flight activities in seed potato crops in Serbia
(Pensoft Publishers, Sofia, 2013)
Aphid flight activities in seed potato fields have been studied by the yellow water traps. It is a good method for monitoring aphids as vectors of viruses, but this study also showed it is a suitable method for insect-diversity ...
Testing of self-(in)compatibility in apricot cultivars from European breeding programmes
(Czech Academy Agricultural Sciences, Prague, 2013)
Self-(in)compatibility was tested in 40 new apricot cultivars from European breeding programmes Pollen-tube growth in pistils from laboratory pollinations was analysed using the fluorescence microscopy. Cultivars were ...
Integration of biological control agents and systemic acquired resistance inducers against bacterial spot on tomato
(Amer Phytopathological Soc, St Paul, 2005)
Two strains of plant growth-promoting rhizobacteria, two systemic acquired resistance inducers (harpin and acibenzolar-S-methyl), host-specific unformulated bacteriophages, and two antagonistic bacteria were evaluated for ...
Grain characteristics and composition of maize specialty hybrids
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, 2011)
Improved nutritive and technological maize grain value is very important for its use in diets. In this work, the chemical composition and potential beneficial components, including total and soluble proteins, tryptophan, ...
A leaf spot and blight of greenhouse tomato seedlings incited by a Herbaspirillum sp.
(Amer Phytopathological Soc, St Paul, 2007)
A leaf spot and blighting were observed on leaves of tomato transplants from a producer in Florida in 2001 and 2002. A nonfluorescent bacterium was isolated consistently from affected tissue. The typical bacterium was a ...
Synthesis of BaTiO3 from a mechanically activated BaCO3-TiO2 system
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
