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

TRŽIŠTE MESA DIVLJAČI U ISTOČNOJ HRVATSKOJ

In the Republic of Croatia, game meat is consumed far less than meat of domestic animals. Yearly game meat consumption amounts to only 0.55 kg per household member. Consumers prefer meat of domestic animals, because it is cheaper, not paying attention to specific nutritive advantages of game meat. A research on the game meat market and consumers’ preferences was carried out on 101 examinees, chosen among inhabitants of Slavonia and Baranja. The majority of questioned inhabitants did consume game meat (92%), of whom 66% consider game meat to be of better quality than meat of domestic animals. Significant number of examinees considers game meat as healthy food, being also convinced that game was healthier to consume if hunted in their natural environment, than if reared on specialized farms (90%). Irrespective of quality, only 22% of examinees buy game meat, and 51% think such meat is too expensive. This is the main reason why consumers have game meat only once a month (51%). Taking into consideration monthly income of their respective household, 58% of examinees can afford game meat only once a month, and, if having an opportunity, they would opt for meat of roe deer (55%) and rabbit (25%). When asked what would stimulate the game meat market in Croatia, 56% of examinees believe this could be achieved by lowering of prices, 27% think the issue could be addressed by opening of specialty stores, and only 17% opted for more aggressive marketing activities.Meso divljači se u Republici Hrvatskoj konzumira u znatno manjim količinama od mesa domaćih životinja. Potrošnja mesa divljači iznosi svega 0,55 kg po članu domaćinstva godišnje. Potrošači preferiraju cijenom povoljnije meso domaćih životinja, bez obzira na pojedine nutricionističke prednosti mesa divljači. Istraživanje tržišta mesa divljači i preferencije potrošača provedeni su na 101 ispitaniku među stanovništvom Slavonije i Baranje. Većina anketiranih stanovnika konzumirala je meso divljači (92%) i misli da je ono kvalitetnije od mesa domaćih životinja (66%). Značajan broj anketiranih smatra da je meso divljači ekološki zdrava hrana i da je zdravije ukoliko se divljač odstrijeli u prirodi, nego da je podrijetlom sa specijaliziranih farmi (90%). Bez obzira na kvalitetu, tek 22% ispitanika kupuje meso divljači, a 51% anketiranih smatra da je ono preskupo. To je i glavni razlog što je meso divljači na stolu potrošača tek jednom mjesečno (51%). S obzirom na mjesečna primanja članova, 58% anketiranih u mogućnosti je konzumirati meso divljači samo jednom mjesečno, a najradije bi izabrali meso srneće divljači (55%) i zeca (25%). Na temelju provedene ankete, tržište mesa divljači moguće je poboljšati sniženjem cijena, što smatra 56% ispitanika, dok 27% misli da bi se ono poboljšalo otvaranjem specijaliziranih prodavaonica, a tek 17% ispitanika izjasnilo se za jaču marketinšku aktivnost

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$^3$). 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 μ+μ−\mu^+\mu^- Data within a Relativistic Transport Approach

We present a nonperturbative dynamical study of $\mu^+\mu^-$ 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 $\leq$ 1.6 GeV is found to be dominated by the decays of the $\eta, \rho, \omega$ and $\Phi$ mesons. For 200 GeV/A S + W collisions, however, the dimuon yield shows an additional large contribution from $\pi^+\pi^-$, $K^+K^-$ and $\pi \rho$ 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 $\leq$ m $\leq$ 0.65 GeV and that the HELIOS-3 data can only be reproduced within a hadronic scenario, if the $\rho/\omega$-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. imageBundesministerium für Bildung und Forschung http://dx.doi.org/10.13039/501100002347FP7 People: Marie‐Curie Actions http://dx.doi.org/10.13039/10001126

Theory of Photoluminescence of the ν=1\nu=1 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 $\nu=1$ 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 $\nu=1$. 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 $\sigma_-$ 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 $\nu=1$ state.Comment: 23 pages, 7 postscript figures included.

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
