Volatile constituents of Achillea serbica Nym.
(John Wiley and Sons Ltd, 2000)
The volatile constituents of Achillea serbica Nym. (Asteraceae), an endemic plant of the Balkan Peninsula, has been analysed using GC and CC-MS. Fifteen identified components constituted 95.7% of the oil. The major fractions ...
The Effect of Some parameters of Electrolysis on Apparent Density of Electrolytic Copper Powder in Galvanostatic Deposition
(Switzerland : Trans Tech Publications Ltd, 2000)
The investigation on some properties of electrochemically deposited copper powders from copper sulphate - sulfuric acid has been performed. Relations between conditions of electrolysis of powder storage, apparent density ...
The Preferred Orientation of Bright Copper Deposits
(Switzerland : Trans Tech Publications Ltd, 2000)
The preferred orientations of copper deposits obtained from acid sulfate solutions were examined. Mat deposits obtained in the absence of the additives and in the presence of disodium 2-naphtol-3,6-disulfonic acid possessed ...
Desinfectants in food industry / Sredstva za dezinfekciju u prehrambenoj industriji
(Prehrambena industrija - mleko i mlečni proizvodi, 2000)
In this paper a review of disinfectants used in food industry is given. Desinfectants covered in the review are: amonium quartenairy-compounds, chlorine-based products, ampholities, iodophores, cresole acid comounds, phenole ...
Composition and antibacterial activity of achillea chrysocoma essential oil
(Taylor & Francis, 2000)
Essential oil of Achillea chrysocoma Friv. was investigated for composition and antibacterial activity. Twenty-eight identified compounds constituted 91.5% of the oil. The main compounds of the oil were borneol (10.1%), ...
The influence of the aging time of RuO2 and TiO2 sols on the electrochemical properties and behavior for the chlorine evolution reaction of activated titanium anodes obtained by the sol-gel procedure
(Elsevier, 2000)
The influence of the aging time of RuO2 and TiO2 sols used for the preparation of (40% RuO2+60% TiO2)/Ti anodes by the sol-gel procedure on the electrochemical properties and behavior for the chlorine evolution reaction ...
An efficient semisynthesis of 7-deoxypaclitaxel from taxine
(Journal of the Chemical Society, Perkin Transactions 1, 2000)
A semisynthesis of 7-deoxypaclitaxel 4 is described, starting from taxine 6 - the most abundant naturally occurring taxane diterpene fraction. A key step in this transformation is a tandem reaction: stereoselective osmylation ...
Investigation of ion-beam modified silicon by photoacoustic method
(IEEE Computer Society, 2000)
Thermal, elastic and electronic transport properties of ion-modified silicon samples were investigated by a photoacoustic frequency transmission technique. The experimental photoacoustic data vs the modulating frequency ...
Selective area epitaxial growth of Hg1-xCdxTe by isothermal vapor-phase epitaxy
(IEEE Computer Society, 2000)
We used mechanical shadow masks, which are made by silicon micromachining, to obtain selective area epitaxial (SAE) growth of (Hg,Cd)Te on CdTe substrates. The layers were grown by isothermal vapor phase epitaxy (ISOVPE) ...
The Schottky barrier contribution to photoacoustic effect in Au-Si system
(IEEE Computer Society, 2000)
The photoacoustic effect in metal-semiconductor system, i.e., the influence of Schottky barrier on the thermal and electronic transport processes in semiconductor was investigated. The amplitude and phase spectra were ...
