Svojstva i dinamika promjena organske tvari u Jadranu
-
Jelena Dautović Organski ugljik važan je indikator globalnih promjena te sudjeluje u mnogim
biogeokemijskim procesima u moru. Ovaj rad dokumentira dinamiku promjena sadržaja i
svojstava otopljene organske tvari/ugljika, u odabranim područjima Jadrana koja su pod jakim
utjecajem unosa slatke vode kao i različitih vodenih masa: sjeverni Jadran (SJ) na profilu Rovinj
– rijeka Po, Boka kotorska i albanski šelf. Ispitivani su sadržaj i svojstva otopljenog organskog
ugljika (eng. DOC),...

Synthesis and intercalation of epitaxial graphene on iridium
-
Marin Petrović Epitaxial graphene on iridium (111) surface is considered to be one of the best systems for studying intrinsic properties of graphene due to the weak interaction with the substrate which is predominantly of the van der Waals character. In epitaxial systems, graphene’s properties can be modified or some new ones can be induced by the processes of intercalation of various atoms or molecules in between the graphene and the substrate. Therefore, a detailed understanding of the formation of...

Synthetic Lorentz force for neutral cold atoms
-
Neven Šantić Presented in this thesis are results of research on two topics in the field of cold atoms. These topics are connected by the fact they both employ laser induced forces caused by momentum transfer from photons to atoms. In both cases the laser induced forces change the velocity distribution of the atomic ensemble. In the first part of the thesis a new way to implement a synthetic Lorentz force into a cold atomic gas is presented. The synthetic Lorentz force (SLF) is based on radiation...

Synthetic magnetism in quantum gases and photonic lattices
-
Tena Dubček Many intriguing phenomena in modern physics are rooted in the coupling of electric charge to magnetic fields. However, it mostly includes quantum many-body systems, which makes these systems hard to address both experimentally—because of the rather extreme conditions they usually require, and theoretically—because of the exponential dependence of the required classical computer memory on the number of quantum system constituents. The solution is found by following Feynman’s idea of the...

THE LONGITUDINAL IMPACT OF MULTIPLE STRESSORS ON THE
BENTHIC INVERTEBRATE COMMUNITY IN THE BEDNJA RIVER
-
Iva Vidaković Maoduš The impact of water quality, landuse, hydromorphology on benthic macroinvertebrate
assemblages of the Bednja River was studied. 20 longitudinally distributed study sites
were sampled using the AQEM multihabitat sampling method resulting in the collection
and identification of 193,638 benthic macroinvertebrate individuals belonging to 259
taxa. Diversity and assemblage composition greatly varied between the study sites and
microhabitats. There was no grouping of communities based on...

THE ROLE OF MATH-BTB FAMILY PROTEINS TaMAB2 AND AtBPM1 IN PLANT
DEVELOPMENT AND STRESS RESPONSE
-
Andreja Škiljaica MATH-BTB proteins are substrate-specific adaptors of CUL3-based E3 ligases, promoting
ubiquitination and proteasomal degradation of target proteins. In this work, MATH-BTB proteins
of wheat Triticum aestivum (TaMAB) and Arabidopsis thaliana (AtBPM) were phylogenetically
analyzed. Forty-six putative TaMAB genes retrieved from EnsemblPlants database clustered in the
grasses-specific expanded clade of MATH-BTB proteins. AtBPM proteins characteristically
clustered in the smaller core clade....

THE ROLE OF MITOTIC KINESINS AND CROSSLINKERS NUMA AND PRC1 IN
THE MICROTUBULE POLEWARD FLUX REGULATION DURING
PROMETAPHASE
-
Jelena Martinčić Microtubule poleward flux is a fascinating phenomenon that occurs throughout mitosis,
including prometaphase. Studying the involvement of different proteins in prometaphase flux
regulation is challenging because of high dynamics of microtubule and chromosome
movements in this phase. Here I show that the prometaphase spindle consists of k-fibers and
bridging fibers, and their poleward flux velocities are similar as in metaphase. By using
tubulin photoactivation and speckle...

THE ROLE OF de novo DNA METHYLATION IN PLANT RESPONSE TO ELEVATED TEMPERATURE
-
Tokić Mirta One of the key factors affecting plant survival and agricultural yield production is temperature. In this thesis, effects of prolonged 37 °C and short-term 45 °C heat treatments were investigated in Arabidopsis thaliana, Brassica rapa ssp. pekinensis and Solanum lycopersicum. Elevated temperatures negatively affected germination, development, shoot and root growth, and flower morphology. Seedlings and inflorescences were more thermosensitive than leaves of adult plants. Global DNA...

Taksonomija i biološke značajke mekousne Salmo obtusirostris (Heckel, 1851) (Actinopterygii, Salmonidae)
-
Aljoša Duplić Ovim istraživanjem prvi puta su komparativno analizirana morfološka, fenološka i genetička obilježja populacija mekousne (Salmo obtusirostris (HECKEL, 1851)) iz rijeka Jadra, Vrljike, Neretve i Zete. Značajno su povećana znanja o morfometriji i meristici tih populacija te o filogenetskim odnosima, temeljeno na analizi mitohondrijske DNK (gen cyt b) i nuklearne DNK (gen RAG1). Ovo istraživanje pokazalo je da između populacija mekousne ne postoji izmjena genetskog materijala te da...

Taksonomske i biološko-ekološke značajke roda Telestes Bonaparte 1837(Actinopterygii) na području Velike i Male Kapele
-
Zoran Marčić U ovom su radu prvi put istražene taksonomske te biološko-ekološke značajke riba iz roda Telestes na području Velike i Male Kapele. Uzorak je prikupljen elektroribolovom, a dodatni podaci prikupljeni su metodom opažanja tijekom ronjenja. Ovim je istraživanjem dokazano da na području istraživanja dolaze dvije vrste unutar ovog roda; svijetlica - T. polylepis sa sjeveroistočne strane i kapelska svijetlica - T. karsticus s jugozapadne strane planina Velike i Male Kapele. Znatno su se...

Taloženje kalcijeva karbonata u umjetnoj krškoj vodi uz dodatak odabranih okolišnih i antropogenih molekula
-
Nives Matijaković Mlinarić U ovom radu sustavno su, kroz dulji period, provedene fizičko-kemijske analize krške vode i sedre na odabranim lokacijama Nacionalnog parka Plitvička jezera. Zbog intenzivne mineralizacije, visokog pH i prezasićenosti kemijski sastav krške vode na jezeru Novakovića brod odabran je kao najreprezentativniji za usporedbu taloženja u prirodi te u laboratorijskim uvjetima, u umjetnoj krškoj vodi. Korištenjem standardnog laboratorijskog modela taloženja kalcijeva karbonata (CaCO3),...

Taloženje kalcijevih oksalata u uvjetima hiperoksalurije: utjecaj aminokiselina relevantnih za patološku biomineralizaciju
-
Anamarija Stanković U ovom radu provedena su sustavna istraživanja spontanog taloženja kalcijeva oksalata pri tri različite kompleksnosti (jednostavan sustav, NaCl sustav i sustav umjetnog urina) i pri dva početna pH (pHi = 5,0 i pHi = 9,0). U svim sustavima dominantno taloži kalcijev oksalat monohidrat (COM) osim u sustavu umjetnog urina pri pHi = 9,0, ci(C2O42-) ≥ 6,0 mmol dm-3 i ci(Ca2+) ≥ 7,5 mmol dm-3 gdje taloži smjesa COM i kalcijeva oksalata dihidrata (COD). Istraženo je djelovanje sedam...
