Overview of the IPARD Program Funds Usage in the Republic of Croatia
The Instrument of Pre-Accession Assistance – IPA was offered as an aid to the Republic of Croatia for implementation of required reforms within its preparation for full membership in the European Union. The assistance is aimed to support the set-up of a system for efficient management of European Union funds. The IPA program was established by the EU Council Regulation no. 1085/2006, which defines general principles and assistance framework. Detailed provisions are defined in the Regulation no. 718/2007, made up of five components: IPA-TAIB, IPA-CBC, IPA-RD, IPA-HRD and IPARD. Financial framework of the Program is determined by the Multiannual Financial Framework of the European Commission - MFF for each participating country in the IPA components. The main objective of the IPARD program is to improve the agricultural sector and its market efficiency according to the EU standards, to implement preparatory activities for incorporation of agricultural and environmental measures and the LEADER, as well as to develop rural economy. The IPARD program in the Republic of Croatia is carried out through the Measure 101 “Investments in agricultural holdings to restructure and upgrade to the EU standards”, Measure 103 “Investments in processing and marketing of agriculture and fishery products to restructure and upgrade to the EU standards”, Measure 301 “Improvement and development of rural infrastructure”, Measure 302 “Development and diversification of rural economic activities” and Measure 202 “Preparation and implementation of local rural development strategies”. The objective of presented paper is to overview the usage of IPARD funds in the Republic of Croatia in the period 2010-2013
POVEĆANJE SADRŽAJA N-3 PUFA U JAJIMA
The research on effects of different oils on the profile of fatty acids in egg yolks was performed on 80 ISA Brown laying hens (40 in control and 40 in experimental group). Hens were 50 weeks old. The control group of hens was fed diets supplemented with sunflower oil (6%), and the experimental group was given a combination of rapeseed oil (4%) and fish oil (2%). Hens’ diets contained 16.8% of crude protein and 11.57 MJ ME. The research lasted for 28 days. Content of fatty acids in yolk lipids was determined on 10 samples taken from each group. Supplemented oils (sunflower, rapeseed and fish oil) in hens’ diets had significant effect on the profile of fatty acids in yolk lipids. Compared to the control group, yolk lipids of eggs produced by hens in the experimental group contained significantly higher (P<0.001) portion of favorable fatty acids (linolenic, C18:3n-3; eicosapentaenoic, C20:5n-3 and docosahexaenoic, C22:6n-3). Moreover, the experimental group of hens laid eggs that contained less unfavorable saturated fatty acids (P<0.001) and less linoleic (C18:2n-6) and arachidonic acid (C20:4n-6) in their lipids. Content of oleic acid (C18:1) and total monounsaturated fatty acids (MUFA) was significantly higher (P<0.001) in yolk lipids of the experimental group. The experimental group contained less unfavorable polyunsaturated fatty acids of the n-6 type (n-6 PUFA, P<0.001), more favorable fatty acids of the n-3 type (n-3 PUFA, P<0.001) and more favorable n-6 / n-3 PUFA ratio (P<0.001) in yolk lipids than the control group.Istraživanje utjecaja različitih ulja na profil masnih kiselina u žumanjcima jaja obavljeno je na 80 ISA Brown nesilica (40 u kontrolnoj i 40 u pokusnoj skupini) starih 50 tjedana. Kontrolna skupina nesilica dobivala je u hrani suncokretovo ulje (6%), a pokusna skupina kombinaciju repičinog (4%) i ribljeg (2%) ulja. Smjese za nesilice sadržavale su 16,8% sirovih bjelančevina i 11,57 MJ ME. Istraživanje je trajalo 28 dana. Sadržaj masnih kiselina u mastima žumanjka određen je na 10 uzoraka iz svake skupine. Korištena ulja (suncokretovo, repičino i riblje) u hrani za nesilice imala su značajan utjecaj na profil masnih kiselina u mastima žumanjaka jaja. U mastima žumanjaka kod pokusne skupine nesilica utvrđen je značajno veći (P<0,001) sadržaj poželjnih masnih kiselina (linolenske, C18:3n-3; eikozapentaenske, C20:5n-3 i dokozaheksaenske, C22:6n-3) u odnosu na kontrolnu skupinu. Osim toga, pokusna skupina nesilica imala je manji sadržaj (P<0,001) nepoželjnih zasićenih masnih kiselina te linolne (C18:2n-6) i arahidonske kiseline (C20:4n-6) u mastima žumanjaka. Sadržaj oleinske kiseline (C18:1) i ukupnih mononezasićenih masnih kiselina (MUFA) bio je značajno veći (P<0,001) u mastima žumanjaka pokusne skupine. Pokusna skupina nesilica imala je manji sadržaj nepoželjnih polinezasićenih masnih kiselina n-6 tipa (n-6 PUFA, P<0,001), veći sadržaj poželjnih masnih kiselina n-3 tipa (n-3 PUFA, P<0,001) i povoljniji omjer n-6 / n-3 PUFA (P<0,001) u mastima žumanjaka jaja odnosu na kontrolnu skupinu
Evidence of early multi-strange hadron freeze-out in high energy nuclear collisions
Recently reported transverse momentum distributions of strange hadrons
produced in Pb(158AGeV) on Pb collisions and corresponding results from the
relativistic quantum molecular dynamics (RQMD) approach are examined. We argue
that the experimental observations favor a scenario in which multi-strange
hadrons are formed and decouple from the system rather early at large energy
densities (around 1 GeV/fm). The systematics of the strange and non-strange
particle spectra indicate that the observed transverse flow develops mainly in
the late hadronic stages of these reactions.Comment: 4 pages, 4 figure
Analysis of the HELIOS-3 Data within a Relativistic Transport Approach
We present a nonperturbative dynamical study of production in
proton-nucleus and nucleus-nucleus collisions at SPS energies on the basis of
the covariant transport approach HSD. For p + W reactions at 200 GeV bombarding
energy the dimuon yield for invariant masses m 1.6 GeV is found to be
dominated by the decays of the and mesons. For 200
GeV/A S + W collisions, however, the dimuon yield shows an additional large
contribution from , and channels. We find that
for `free' meson masses and form factors the experimental cross section is
clearly underestimated for S + W in the invariant mass range 0.35 GeV m
0.65 GeV and that the HELIOS-3 data can only be reproduced within a
hadronic scenario, if the -meson mass drops with baryon density.
This finding suggests a partial restoration of chiral symmetry in S + W
collisions at SPS energies.Comment: 11 pages, 5 postscript figure
Improved understanding of dynamic water and mass budgets of high‐alpine karst systems obtained from studying a well‐defined catchment area
Large areas of Europe, especially in the Alps, are covered by carbonate rocks and in many alpine regions, karst springs are important sources for drinking water supply. Because of their high variability and heterogeneity, the understanding of the hydrogeological functioning of karst aquifers is of particular importance for their protection and utilisation. Climate change and heavy rainfall events are major challenges in managing alpine karst aquifers which possess an enormous potential for future drinking water supply. In this study, we present research from a high‐alpine karst system in the UNESCO Biosphere Reserve Großes Walsertal in Austria, which has a clearly defined catchment and is drained by only one spring system. Results show that (a) the investigated system is a highly dynamic karst aquifer with distinct reactions to rainfall events in discharge and electrical conductivity; (b) the estimated transient atmospheric CO2 sink is about 270 t/a; (c) the calculated carbonate rock denudation rate is between 23 and 47 mm/1000a and (d) the rainfall‐discharge behaviour and the internal flow dynamics can be successfully simulated using the modelling package KarstMod. The modelling results indicate the relevance of matrix storage in determining the discharge behaviour of the spring, particularly during low‐flow periods. This research and the consequent results can contribute and initiate a better understanding and management of alpine karst aquifers considering climate change with more heavy rainfall events and also longer dry periods.The investigated karst system contributes to the transient atmospheric CO2 sink with about 270 t/a.
Carbonate denudation rates vary between 23 and 47 mm/1000a.
Rainfall‐discharge modelling results indicate the importance of matrix storage particularly during low‐flow periods.

Theory of Photoluminescence of the Quantum Hall State: Excitons, Spin-Waves and Spin-Textures
We study the theory of intrinsic photoluminescence of two-dimensional
electron systems in the vicinity of the quantum Hall state. We focus
predominantly on the recombination of a band of initial ``excitonic states''
that are the low-lying energy states of our model at . It is shown that
the recombination of excitonic states can account for recent observations of
the polarization-resolved spectra of a high-mobility GaAs quantum well. The
asymmetric broadening of the spectral line in the polarization is
explained to be the result of the ``shake-up'' of spin-waves upon radiative
recombination of excitonic states. We derive line shapes for the recombination
of excitonic states in the presence of long-range disorder that compare
favourably with the experimental observations. We also discuss the stabilities
and recombination spectra of other (``charged'') initial states of our model.
An additional high-energy line observed in experiment is shown to be consistent
with the recombination of a positively-charged state. The recombination
spectrum of a negatively-charged initial state, predicted by our model but not
observed in the present experiments, is shown to provide a direct measure of
the formation energy of the smallest ``charged spin-texture'' of the
state.Comment: 23 pages, 7 postscript figures included. Revtex with epsf.tex and

Cave deposits as a sedimentary trap for the Marine Isotope Stage 3 environmental record: The case study of Pod Hradem, Czech Republic
Pod Hradem Cave, located in the Moravian Karst, Czech Republic, offers an excellent opportunity for environmental reconstructions of Marine Isotope Stage 3 (MIS 3) in Central Europe due to its detailed sedimentary record dated 50,000 to 28,000 cal BP. Identifying the natural environments of the Middle to Upper Palaeolithic (MUP) transition is necessary to understand the settlement strategies and related behaviour of both Neanderthals and Anatomically Modern Humans, both of whom may have occupied the region at the same time. A multidisciplinary excavation was carried out between 2011 and 2016. Detailed analyses of the sediments, vertebrate microfauna, pollen and charcoal revealed minor but observable fluctuations in climate, with little change in the surrounding vegetation. The Pod Hradem palaeoenvironmental dataset is complex, but generally reflects a predominantly glacial climate with a range of vegetation types and habitats during the Late Pleistocene, followed by the warmer and more humid Holocene. The MUP transition as recorded in Pod Hradem Cave was a glacial environment interrupted by two relatively warmer periods. Central Europe experienced extreme climate fluctuations during MIS3, as recorded from different sedimentary archives, but it seems that the Pod Hradem Cave environment may have acted as a buffer zone, ameliorating those extremes, and providing a suitable refuge for both bears seeking winter hibernation dens and occasionally visiting humans.Thisproject was funded from the SoMoPro programme.

Optical application and measurement of torque on microparticles of isotropic nonabsorbing material
We show how it is possible to controllably rotate or align microscopic
particles of isotropic nonabsorbing material in a TEM00 Gaussian beam trap,
with simultaneous measurement of the applied torque using purely optical means.
This is a simple and general method of rotation, requiring only that the
particle is elongated along one direction. Thus, this method can be used to
rotate or align a wide range of naturally occurring particles. The ability to
measure the applied torque enables the use of this method as a quantitative
tool--the rotational equivalent of optical tweezers based force measurement. As
well as being of particular value for the rotation of biological specimens,
this method is also suitable for the development of optically-driven
micromachines.Comment: 8 pages, 6 figure
