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 ...
Separability degree of clusters based on the production results indicator / Stepen razdvajanja izdvojenih klastera na osnovu indikatora rezultata proizvodnje
(Univerzitet u Beogradu - Poljoprivredni fakultet, Beograd, 1999)
The business result of a family farm is a multidimensional criterion. There are, however, difficulties in determining homogenous subsets, considering the pace and movement trends of the indices of production results. The ...
The application of the electronic and the X-ray photoelectric spectroscopy (XPS) for the examination of the passivization film on the tinplate / Primena elektronske i fotoelektronske spektroskopije X-zracima (XPS) za ispitivanje sastava pasivizacionog filma na belom limu
(Univerzitet u Beogradu - Poljoprivredni fakultet, Beograd, 1999)
The structure of passivization film has an important role in the adhesion of lacquer on the tinplate, and also in further behavior of the can filled with a different content. It is for this reason that the composition of ...
The biodegradation of wheat straw by Pleurotus ostreatus mushrooms and its use in cattle feeding
(Elsevier, Amsterdam, 1998)
The influence of Pleurotus ostreatus enzymes on wheat straw degradation was investigated in laboratory conditions. Chopped and pressure-pasteurized straw with 24% dry matter was seeded with mushroom mycelium. Analyses of ...
Effects of trifluralin on carp: Biochemical and histological evaluation
(Academic Press Inc Elsevier Science, San Diego, 1999)
Acute and subacute toxicity of the herbicide trifluralin on fish was investigated in laboratory toxicity tests with carp, Median lethal concentrations were determined in acute tests. The 96-h LC50 value was 0.045 (0.036-0.051) ...
Effect of convective mass transfer on beer diafiltration
(Inst Brewing, London, 1997)
The industrial application of dialysis for the de-alcoholization of beer is based on a diafiltration method, because a small positive transmembrane pressure an the beer side of the membrane is necessary to prevent ingress ...
Discrimination between some Chinese and Yugoslav winter wheat cultivars by capillary electrophoresis of gliadins
(Seed Science and Technology, 1998)
Gliadin proteins extracted from seventeen China and Yugoslav winter wheat cultivars were separated by capillary electrophoresis (CE). In order to optimise resolution and reproducibility of gliadin separations, different ...
Potentiometric titration of pralidoxime chloride (2-pyridinealdoxime methochloride) with a silver indicator electrode
(Journal of Analytical Chemistry, 1998)
It is shown that a silver indicator electrode can be used in the potentiometric titration of pralidoxime chloride [2-pyridinealdoxime methochloride (PAM-2)] with palladium(II) chloride and silver nitrate solutions. The ...
Capillary zone electrophoresis analysis of gliadin proteins from Chinese and Yugoslav winter wheat cultivars
(Kluwer Academic Publ, Dordrecht, 1999)
Gliadin proteins extracted from fifteen Chinese and Yugoslav winter wheat cultivars were fractionated using a new separation technique - Capillary Zone Electrophoresis (CZE). Different CZE conditions were defined to optimize ...
Observations on spear replacement in Xiphinema dentatum (Nematoda : Longidoridae)
(Brill Academic Publishers, Leiden, 1998)
The process of spear (odontostyle + odontophore) replacement was determined by studying juveniles of Xiphinema dentatum in different phases of moulting. The process is subdivided into eight distinct phases, each readily ...
