Lepton favor violation in supersymmetric low-scale seesaw models
-
Luka Popov The minimal supersymmetric standard model with a low scale see-saw mechanism is presented. Within this framework, the lepton flavour violation in the charged lepton sector is thoroughly studied. Special attention is paid to the individual loop contributions due to the heavy neutrinos N1,2,3, sneutrinos e N1,2,3 and soft SUSY-breaking terms. For the first time, the complete set of box diagrams is included, in addition to the photon and Z-boson mediated interactions. The complete set of chiral...

Life cycle and ecology of the loggerhead turtle (Caretta caretta, Linnaeus, 1758)
-
Nina Marn After the general introduction presented in Chapter 1, Chapter 2 tackles the problem of disjointed and conflicting data, and explores to what extent do loggerhead turtle populations and life stages differ in morphology. In order to take into account the possible geographic and life stage variability, I study two neighboring populations and all postembryonic life stages by comparing the ratio of carapace length, width and height of sea turtles. I conduct a detailed analysis of empirical...

Local probe investigation of trivalent rare-earth titanates
-
Ana Najev This thesis contains an in-depth experimental investigation of trivalent rare-earth titanates. Titanates are a model system for exploring intricate interactions between spin, orbital, and lattice degrees of freedom. These compounds belong to a broader family of transition metal oxides. Their ground state can be easily manipulated by strain, chemical, and charge doping, offering a unique opportunity to explore the Mott insulator phase and metal-insulator transitions. One of the foremost open...

Lokalna asimptotska svojstva aproksimativnoga procjenitelja maksimalne vjerodostojnosti parametara pomaka u difuzijskom modelu
-
Snježana Lubura Strunjak Difuzijski modeli rasta imaju važnu primjenu u biomedicinskim istraživanjima, posebno u modeliranju rasta tumora. Parametri modela se uobičajeno procjenjuju metodom najveće vjerodostojnosti iz diskretnih opservacija trajektorija. Budući da nije uvijek moguće eksplicitno izraziti funkciju vjerodostojnosti, a time i procjenitelj metodom maksimalne vjerodostojnosti, na osnovu diskretnih opservacija, parametri modela se procjenjuju drugim metodama. Posebno su zanimljivi aproksimativni...

Low-level turbulence characteristics over inhomogeneous surface during wintertime
-
Karmen Babić In this dissertation, the local similarity scaling approach was examined based on the multi-level measurements of atmospheric turbulence in the wintertime (December 2008 February 2009) stable atmospheric boundary layer (SBL) established over a heterogeneous surface influenced by mixed agricultural, industrial and forest surfaces. The 62 m tower (levels 20, 32, 40, 55 and 62 m above ground) was situated in the middle of some 120 m × 480 m area of hc = 18 m high walnut trees. The...

MECHANISM OF CHROMOSOME ALIGNMENT BY MICROTUBULE OVERLAPDEPENDENT FORCES AND ITS RELEVANCE FOR CHROMOSOME
SEGREGATION ERRORS
-
Patrik Risteski Chromosome alignment is a hallmark of mitosis and alignment defects, which persist in
anaphase, lead to direct aneuploidy. Alignment at the spindle equator depends on pulling forces
exerted at kinetochore fiber tips together with polar ejection forces. However, kinetochore
fibers are also subjected to forces that drive their poleward flux. Here I introduce a microtubule
flux-driven centering mechanism that relies on flux generated by forces within the overlaps of
bridging and...

MEĐUODNOS BDNF, IL-6 I POKAZATELJA OKSIDACIJSKOG STRESA PRI DEMIJELINIZACIJSKIM OŠTEĆENJIMA
-
Andrijana Bogoje Raspopović BDNF, IL-6 i biljezi oskidacijskog stresa nedvojbeno imaju utjecaj na demijelinizacijski proces umultiploj sklerozi. Točni mehanizmi utjecaja na upalnu i neurodegenerativnu fazu nisu upotpunosti razjašnjeni. U ovo istraživanje je uključeno 60 ispitanika (19 muških i 41 ženskih)koji zadovoljavaju kriterije relapsno remitentne multiple skleroze (RRMS), i 66 zdravihkontrola (24 muških, 42 ženskih). Srednja dob oboljelih i zdravih je 43,5 godina. Iz krviispitanika određena je razina...

MOLECULAR IDENTIFICATION OF FRESHWATER PATHOGENIC OOMYCETES
AND DETERMINATION OF NOVEL FACTORS THAT PROMOTE THEIR
SPREADING
-
Dora Pavić Aphanomyces astaci and Saprolegnia spp. are considered as the most destructive Oomycota
pathogens of freshwater animals, both in natural habitats and in aquaculture, and this dissertation
addressed several understudied aspects of their ecology. First, a highly sensitive S. parasiticaspecific ddPCR assay was developed, which allowed absolute quantification of the pathogen in
environmental DNA samples. Further, the results obtained provided information on the
microbiological and...

Mate Čarija Virus uvijenosti lista vinove loze 3 (grapevine leafroll-associated virus 3, GLRaV-3,
Closteroviridae) uzročnik je bolesti uvijenosti lista, jedne od ekonomski najznačajnijih viroza
vinove loze. U ovom istraživanju, u uzorcima 16 autohtonih dalmatinskih sorti i klonskih
kandidata sorte 'Plavac Mali', primjenom molekularnih metoda napravljen je pregled
pojavnosti ekonomski štetnih virusa vinove loze uz poseban osvrt na genomske varijante
GLRaV-3. Utvrđena je dominantna pojavnost...

Magnetotransport properties of selected high entropy alloys
-
Marko Kuveždić This thesis presents the findings of a comprehensive, systematic study of transport properties, including resistivity, Hall effect, magnetoresistance, and superconductivity, in amorphous quinary alloys of early and late transition metals. The research focused on metallic glass ribbons from three alloy systems: (TiZrNbNi)1−xCux, (TiZrNbCu)1−xNix, and (TiZrNbCu)1−xCox, spanning a broad composition range, along with three alloy variants with a fixed TL (Cu, Ni) content and compositions:...
