Complexes of iron(II), iron(III) and zinc(II) with condensation derivatives of 2-acetylpyridine and oxalic or malonic dihydrazide. Crystal structure of tris[(1-(2-pyridyl)ethylidene)hydrazine]iron(II) perchlorate
(Springer, Dordrecht, 2005)
Complexes of zinc and iron with N', N'(2)- bis[(1E)-1-(2-pyridyl) ethylidene] ethanedihydrazide (H(2)L1) and N', N'(2)-bis[( 1E)-1-(2-pyridyl) ethylidene] propanedihydrazide (H(2)L2) were prepared. Zn-II complexes with ...
Identification of phytoplasmas associated with grapevine yellows in serbia
(Wiley, Hoboken, 2004)
The molecular identification and characterization of phytoplasmas from infected grapevines in four locations in Serbia are reported. Phytoplasmas were detected and identified by restriction fragment length polymorphism ...
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, ...
A novel tandem process leading to functionalized glutarimides
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
The synthesis of various functionalized or spirobicyclic glutarimides by a novel tandem process has been disclosed. The reaction involves a base-catalyzed Michael addition of active methylene compounds to secondary conjugated ...
The influence of genotypic variation in protein composition on emulsifying properties of soy proteins
(Wiley, Hoboken, 2005)
This study describes the relationship between the emulsifying properties of soybean proteins and their composition, i.e., glycinin (11S) and beta-conglycinin (7S). Twelve investigated soybean genotypes showed significant ...
The effect of microwave roasting on soybean protein composition and components with trypsin inhibitor activity
(Akademiai Kiado Zrt, Budapest, 2005)
The effect of microwave roasting on protease inhibitor activity and Soluble protein content and composition in cracked soybeans was investigated in relation to the duration of treatment. Soybeans of Hodgson var. were cracked ...
Page analysis of milk proteins altered by high thermal treatment
(Akademiai Kiado Zrt, Budapest, 2005)
Changes that occur in milk proteins during heat treatment were studied. Milk was heat treated at 87 degrees C for 10 min. Samples of untreated milk, demineralised whey powder and heat treated milk were analysed by discontinuous ...
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 ...
Investigation of interactions between surface water and petroleum-type pollutants
(Springer Heidelberg, Heidelberg, 2005)
BACKGROUND: , Aims and Scope. In oil spill investigations, one of the most important steps is a proper choice of approaches that imply an investigation of samples taken from different sedimentary environments, samples of ...
Cobalt(III), zinc(II), cadmium(II) and palladium(II) complexes with the hydrolysed and non-hydrolysed condensation products of 2-acetylpyridine with ethyl hydrazinoacetate: X-ray structure analysis of mer-bis{(E)-2-[N '-(1-pyridin-2-yl-ethylidene)hydrazin
(Taylor & Francis Ltd, Abingdon, 2005)
Four Co(III), Zn(II), Pd(II) and Cd(II) complexes with ligands derived in situ from acetylpyridine and ethyl hydrazinoacetate or hydrolysed ethyl hydrazinoacetate were prepared. An X-ray structural analysis showed that the ...
