Composition and antibacterial activity of Achillea asplenifolia essential oil
(Allured Publ Corp, Carol Stream, 2002)
The oil of a wild growing population of Achillea asplenifolia Vent. was studied for yield, composition and antibacterial activity. The major components in the oil were beta-caryophyllene (17.6%), germacrene D (15.6%) and ...
An estimation of the interfacial energy of the copper-copper sulphate solution interface and of the specific surface of copper powder / Procena međupovršinske energije bakar-rastvor bakar sulfata i specifične površine bakarnog praha
(Serbian Chemical Society, 2002)
Apossible way for the estimation of the interfacial energy of the copper – copper sulphate solution interface is proposed. The estimated value of (2.7±0.3) J cm-2 and the derived equations which relate the specific surface ...
Polymorphic transformations of edible vegetable fats / Polimorfne transformacije jestivih biljnih masnoća
(Tehnološki fakultet, Naučni institut za ratarstvo i povrtarstvo i DOO "Industrijsko bilje", Novi Sad, 2002)
Triglycerides are characterized by complex melting behaviour, as reflected by multiple melting temperatures. They can solidify in different crystal structures and this polymorphism can be defined as the ability to reveal ...

Photooxidation of n-heptanal in air: Norrish type I and II processes and quantum yield total pressure dependency
(Royal Society of Chemistry, 2002)
Dilute mixtures of n-heptanal in synthetic air (up to 100 ppm) were photolyzed with fluorescent UV lamps (275-380 nm) at 298 K. The main photooxidation products, identified and quantitatively analyzed by FTIR spectroscopy, ...
Polysulfone membranes for ultra and microfiltration / Polimerne membrane za ultra i mikrofiltraciju na bazi polisulfona
(Tehnika - Novi materijali, 2002)
The influence of the propionic acid as nonsolvent additive on the properties of the prepared polysulfone membranes was investigated. The obtained results show that the membranes prepared from the polymer solutions with ...
Investigation of surface energy states on Si by photoacoustic spectroscopy
(IEEE Computer Society, 2002)
The spectral and dynamic characteristics of surface energy states on Si wafer are investigated by photoacoustic (PA) spectroscopy. The PA spectra were measured as a function of the wavelength and modulation frequency of ...
The roughness analysis of metal coatings by STM technique: Part I: Theoretical survey / Analiza hrapavosti galvanskih prevlaka tehnikom skenirajuće tunelske mikroskopije - deo I - teorijski osnovi
(Belgrade, Serbia : Engineering Society for Corrosion, 2002)
In this work is given theoretical base of methodology which, by use STM technique and corresponding STM software, offers an good conveniences for the examination of mechanism of electrode position process.
Electrochemical behavior of azithromycin on gold electrode / Elektrohemijsko ponašanje azitromicina na elektrodi od zlata
(Pharmaceutical Association of Serbia, Belgrade, Serbia, 2002)
Influence of carrier diffusion on the response of a resonant-cavity enhanced detector
(IEEE Journal of Quantum Electronics, 2002)
We have investigated the effects of carrier diffusion on the impulse response of a resonant-cavity enhanced photodetector using our analytic expression for a short-circuit current. Our theoretical results indicate that ...
