Continental Subduction Tectonics in the High Karst Dinarides of Western Croatia
The faults confining Palaeozoic inliers surrounded by Mesozoic rocks, show that their relation is not a consequence of folding but of neotectonic uplift causing a rather uneven relief of the Palaeozoic units underlying the carbonate Mesozoic. The predominance of tectonic contacts indicates that similar relations exist even between the Triassic and the confined Jurassic outcrops exhibiting inverse and, consequently, allochthonous relations. The allochthony is also confirmed by karst relief within some Triassic dolomites related to the unexpected ground water flow between the swallow holes (ponors) and karst springs. There are also indications of inverse relations between the Triassic volcanics and Palaeozoic clastics. However, in the surrounding area a normal superposition between the Triassic and Jurassic is also noticed. Consequently the Triassic and Jurassic of the Fuzine-Lokve area and of its environs may belong to two megatectonic units. Tectogenesis is explained by continental subduction of the Adriaticum under the Dinaricum
A neuro-fuzzy based combustion sensor for the control of optimal engine combustion efficiency
Modern and advanced control systems for internal combustion engines require accurate feedback information from the combustion chamber. Whereas the in-cylinder pressure sensor provides this information through its close thermodynamic ties with the combustion process, drawbacks in its implementation push research towards other non-intrusive sensing methods. This paper suggests alternative methods of combustion phasing detection relying on measured angular crankshaft speed. Method developed, achieves sensing of angular position of the 50% of mass fraction burned (MFB50) through two steps: calculation of, so called, synthetic torque and its non-linear transformation to a combustion feature estimator through local model. In order to calibrate both parts of this virtual combustion sensor, parameters of a high-fidelity crankshaft dynamic model are identified, and the linear neuro-fuzzy based model is trained with extensive experimentally collected data set. Created virtual MFB50 sensor, demonstrated its performance, on a large test data set comprised of 70% of gathered data
Possibilities to identify engine combustion model parameters by analysis of the instantaneous crankshaft angular speed
In this paper, novel method for obtaining information about combustion process in individual cylinders of a multi-cylinder spark ignition engine based on instantaneous crankshaft angular velocity is presented. The method is based on robust box constrained Levenberg-Marquardt minimization of non-linear least squares given for measured and simulated instantaneous crankshaft angular speed which is determined from the solution of the engine dynamics torque balance equation. Combination of in-house developed comprehensive zero-dimensional two-zone spark ignition engine combustion model and analytical friction loss model in angular domain have been applied to provide sensitivity and error analysis regarding Wiebe combustion model parameters, heat transfer coefficient, and compression ratio. The analysis is employed to evaluate the basic starting assumption and possibility to provide reliable combustion analysis based on instantaneous engine crankshaft angular speed

The Inhibitive Effect of Vitamin-C on the Corrosive Performance of Steel in HCl Solutions - Part II
The inhibitive behaviour of Vitamin C, as a type of green inhibitor, on the corrosive behaviour of stainless-steel (SS) X4Cr13 within an aqueous solution of hydrochloric acid (HCl) was studied at concentration of c= (0.01, 0.1 and 1.0) mol L-1. Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS), was used for the measurements at 25 degrees C. To observe the morphology and microstructures of sample surfaces, after the electrochemical measurements a Scanning electron microscopy (SEM) was used. On the basis of the EDAX analysis within the solution of hydrochloric acid (0.01 mol L-1) with addition of Vitamin-C (0.005 mol L-1) the presence of the feri-chelates on the metal surface could be confirmed. The polarization curves revealed that the studied mixtures of the chosen inhibitor represented mixed-type of the inhibitor. The results show that the inhibition efficiency increases with the increase of the inhibitor concentration. This valid especially in the case of the lowest concentration of HCl (c= 0.01 mol L-1). In addition to this at higher HCl concentration (c= 1.0 mol L-1) the immersion time has a noticeable influence on the inhibitive response. Furthermore, the results obtained in this study showed that the inhibitory effect of Vitamin-C to a great extent on electrode potential
Hole-depletion of ladders in SrCuO induced by correlation effects
The hole distribution in SrCuO is studied by low
temperature polarization dependent O K Near-Edge X-ray Absorption Fine
Structure measurements and state of the art electronic structure calculations
that include core-hole and correlation effects in a mean-field approach.
Contrary to all previous analysis, based on semi-empirical models, we show that
correlations and antiferromagnetic ordering favor the strong chain
hole-attraction. For the remaining small number of holes accommodated on
ladders, leg-sites are preferred to rung-sites. The small hole affinity of
rung-sites explains naturally the 1D - 2D cross-over in the phase diagram of

Structure of topologically closed ORI sequence from dihydrofolate reductase locus in interaction with initiation protein ORC
Replikacija je jedan od osnovnih procesa u ΕΎivotnom ciklusu Δelije. Cilj
replikacije je udvajanje genetiΔkog materijala. Da bi genetiΔki materijal bio pravilno
umnoΕΎen i kasnije razdvojen na Δerke Δelije, razvijen je veliki broj mehanizama
regulacije replikacije. Jedan od naΔina regulacije je pravilan izbor i aktivacija mesta
inicijacije replikacije.
Broj i kompleksnost mesta inicijacije replikacije varira meΔu vrstama. Kod
evolutivno niΕΎih eukariota su jednostavnija, dok su kod viΕ‘ih eukariota
kompleksnija. NaΔin prepoznavanja ovih mesta od strane inicijacionih proteina nije
u potpunosti razjaΕ‘njen.
Ori sekvenca, locirana nizvodno od gena DHFR (dihidrofolat reduktaza)
hrΔka, sadrΕΎi tri definisana ori mesta inicijacije replikacije: ori Ξ², ori Ξ²' i ori Ξ³. Ori Ξ²
sekvenca DHFR je jak replikator i pokazuje aktivnost na ektopiΔnim mestima.
Premda je ori sekvenca DHFR jedna od najbolje okarakterisanih ori sekvenci kod
metazoa i u okviru nje definisani funkcionalno znaΔajni regioni (AT bogati region,
DNR region, BEND, RIP60 region, IR 4 bp), njihova funkcija nije u potpunosti
razjaΕ‘njena.
Protein ORC (eng. Origin recognition complex) je heteroheksamer odgovoran
za prepoznavanje mesta inicijacije replikacije. Pretpostavka je da nekoliko
elemenata ima ulogu u prepoznavanju ori sekvence od strane ORC kompleksa kod metazoa.
Funkcija ljudskog proteina Orc4 (HsOrc4) do sad nije u potpunosti
razjaΕ‘njena. NaΕ‘im prethodnim istraΕΎivanjima, pokazali smo da HsOrc4 prepoznaje nekanonske strukture i ima sposobnost za utiΔe na formiranje TAT
tripleksa i homoadeninskih struktura...Replication is one of the fundamental processes in the life cycle of the cell.
The aim of replication is a duplication of genetic material. To make genetic
material properly duplicated and subsequently divided into daughter cells, a large
number of mechanisms of regulation of replication have been developed. One way
of regulation is the proper selection and activation of replication initiation.
The number and complexity of the origins of replication (ori) varies among
species. They are simpler at evolution lower eukaryotes, while in higher
eukaryotes are more complex. The way of recognizing these places by initiation
proteins is not fully understood.
Ori sequence, located downstream of the DHFR gene (dihydrofolate
reductase) hamster, contains three defined origins of replication: ori Ξ², ori Ξ²' and ori
Ξ³. Ori Ξ² DHFR sequence is strong replicator and shows activity at ectopic places.
Although the sequence of ori DHFR is one of the best characterized ori sequences in
metazoans and within defined functionally important regions (AT rich region,
DNR region, BEND, RIP60 region, IR 4 bp), their function is still not completely
understood.
ORC (Origin recognition complex) is heterohexamer protein responsible for
identifying origins of replication. It is assumed that several elements play a role in
recognizing ori sequences of the ORC complex in metazoans.The function of the human protein Orc4 (HsOrc4) has not been fully
elucidated. Our previous studies showed that HsOrc4 recognize non-canonical
structures and has the ability to influence at formation of TAT triplexes and
homoadenine structures..

policies, and possibilities for such policies to be the base of urban regeneration of small
municipalities. Urban-economic development policies of towns and settlements based
on culture and creativity have become widely accepted, but they are frequently
uncritically implemented. These policies may be recognized in concepts of cultural,
creative city, cultural and creative industries, cultural and creative clusters, and cultural
and creative tourism. They are usually connected to larger towns, but also increasingly
occur in development of smaller towns and settlements; as smaller towns and
settlements do not have usual cultural and creative policy resources, researches point to
the fact that in such cases eligible models are based on development of tourism, based
on local features, and a specific, βnicheβ offer.
The starting assumption is that cultural and creative policies, based on the concept
of clusters, may be the base of urban regeneration of smaller settlements. This is
especially important in the context of Serbia, demographic and economic issues of small
settlements and deliberation of implementation of such policies in urban regeneration.
The second assumption is that methods and models of cultural and creative policies may
be connected to spatial, cultural, and social characteristics, as well as characteristics of
human resources, and that based on these it is possible to define the policy which
corresponds to local conditions. In this context, the municipality of Golubac was
selected as a representative example, due to the characteristics of the municipality and
the projects which have been or are being implemented in it.
The research was conducted by application of several scientific methods, applied in
the area of town planning. The general scientific method employed was analyticalsynthetic, with critical content analysis, logical arguments, deductive method, and case
study method.
The first part of the research comprises an overview of theoretical analyses of
cultural and creative policies, from their emergence, definitions, application of terms,
the accompanying phenomenon of town development and related concepts; it comprises
positive and negative results of their implementation; various examples from practice;
theories and scientific discussions, which altogether point to their complexity and the
need for a different approach. Based on the research of the theoretical base conducted,
classification of methods and models of cultural and creative policies was defined with
the aim to serve as a base for further analytical apparatus of this research
ELECTRODEPOSITION AND MORPHOLOGY OF COPPER POWDER PARTICLES OBTAINED AT DIFFERENT CURRENT REGIMES
The effect different deposition regimes (constant and reversing currents), on the powdered copper electrodeposits morphology were investigated. The morphology of electrodeposited copper powder was investigated using a scanning electron microscope (SEM). The effect of the current amplitude, cathodic to anodic time ratio and period of the current wave are discussed. It is shown that the parameters determining the reversing current wave determine the micro-morphology of the copper powder particles deposited
