AB  - Twenty three crude oils from the Serbian part of the Pannonian Basin (14 from the Vojvodina Province and 9 from the Drmno Depression) were investigated, aimed at an evaluation of oil-oil maturity correlation parameters based on the distribution and abundance of saturated biomarkers and alkylarene constituents. Factor and cluster analyses were used for this purpose. Factor analyses using varimax rotation were first run separately, i.e., of maturity parameters based on the abundance of (a) n-alkanes and isoprenoids, (b) steranes and triterpanes, (c) alkylnaphthalenes, and (d) alkylphenanthrenes. These analyses yielded 9 important "maturity factors". Eight of them, showing higher than 30 % of variance, were further involved in another factor analysis, as well as in cluster analysis using the Ward method. In this way, all maturity parameters based on saturated biomarkers and alkylarenes were evaluated and ranged, considering the fact that the observed factors represented their linear combinations. The results showed that in the correlation of crude oils from the Serbian part of the Pannonian Basin, the most important were maturity parameters based on isomerization reactions involving one methyl group in thermodynamically less stable α-methylnaphthalenes, ethylnaphthalenes, dimethylnaphthalenes and methylphenanthrenes, and their change into more stable isomers with the methyl group in the β-position in the aromatic ring. Processes constituting high loadings factor 2 and factor 3 parameters were also defined. Hierarchy between the "factors" and parameters were controlled, and approved, by cluster analysis using the Ward method. Finally, the investigated crude oils were correlated by factor and cluster analyses, using all the important "maturity factors". Differences in maturity were observed between the Vojvodina and Drmno Depression crude oils, as well as between oils originating from South Banat, North Banat and the Velebit oil field (Vojvodina locality).
AB  - У овом раду је, применом новог приступа у факторској и кластерској анализи, евалуиран значај матурационих параметара заснованих на расподели и обилности засићених биомаркера и алкиларена у корелацији нафта–нафта на примеру 23 узорка сировe нафтe из дела Панонског басена у Србији (14 са локалитета у Војводини и 9 из депресије Дрмно). Факторске анализе су, уз примену varimax ротације, најпре извођене посебно са матура- ционим параметрима израчунатим из расподеле и обилности (а) n-алкана и изопреноидних алифатичних алкана, (б) стерана и тритерпана, (в) алкилнафталена и (г) алкилфенантрена. Ове анализе резултирале су са 9 значајних “матурационих фактора”. Осам од њих, који су показивали проценат варијације већи од 30 %, укључени су у нову факторску и кластерску анализу, уз примену Ward методе. На тај начин су сви матурациони параметри засновани на расподели и обилности засићених биомаркера и алкиларена били процењени и рангирани, имајући у виду чињеницу да фактори предстваљају њихове линеарне комбинације. Резултати су показали да су за корелацију нафти из дела Панонског басена у Србији најзначајанији матурациони параметри засновани на изомеризацији једне алкил-групе из α- у термодина- мички стабилније β-положаје на ароматичном прстену метилнафталена, етилнафталена, ди- метилнафталена, триметилнафталена и метилфенантрена. Такође, одређени су параметри/ти- пови матурационих реакција који су у великој мери дефинисали факторе 2 и 3. Редослед и сагласност између фактора, односно параметара, проверена је и потврђена кластерском ана- лизом уз примену Ward методе. Коначно, испитивани узорци сирове нафте су корелисани помоћу факторске и кластерске анализе, користећи све значајне “матурационе факторе”. Раз- лике у степену термичке зрелости уочене су како између узорака из Војводине и депресије Дрмно, тако и између узорака из Војводине који потичу из лежишта јужног Баната, северног Баната и нафтног поља Велебит.

AB  - It is well known that the deposition conditions such as
bath composition, hydrodynamic regime, temperature,
current density, exhibit a strong effect on the grain size
and the morphology of electrodeposited metal powder
particles [1, 2]. On the other hand it has been shown
recently [3] that similar effects can be obtained by
changing only the shape of the current overpotential
waves in metal powder electrodeposition at a periodically
changing rate with other conditions constant.
This is in accordance with Ibl's observation [4] that, at
one and the same average deposition rate (current
density), it is possible to create a number of different
deposition conditions in the pulsating regimes.
In square-wave pulsating overpotential electrolysis
the overpotential amplitude, frequency of pulsation
and pause-to-pulse ratio can be varied independently.
The purpose of this work is to discuss the effect of the
last parameter on the morphology of electrodeposited
metal powder particles on the basis of the existing
experimental evidence.

studies have been focused on the film formation on mercury [1--3] and
amalgam electrodes [4,5]. Perhaps the most exact information about layer

a study of the formation of thallium oxide monolayer on single crystal gold
electrodes with the (100), (110) and (111) orientations. It has been found
that this two-dimensional (2D) film formation is highly dependent on the

AB  - Two of the stereoisomers of the title compound were prepared and their dipole moments were measured. For the r-1,c-3-dichloro-t-5-methylcyclohexane, the free energy difference between conformers with axial-axial (aa) and equatorial-equatorial (ee) chlorines was measured by a variable temperature NMR method, and the value found was 1.3 ± 0.2 Kcal/mol-1 (in acetone) favoring the latter. Molecular mechanics studies show that the solvation energy and the electrostatics are of major importance in understanding this equilibrium. Calculations show the effect of the methyl group is essentially additive, and give for cis-1,3-dichlorocyclohexane itself ee{measured angle}aa DH+ 3.0 kcal mol-1 (acetone).
