Dynamical electron-phonon interaction in novel quantum materials from first principles
-
Nina Girotto
With the aim of elucidating various experimental results in several relevant novel materials, this thesis delves into clarifying the role of dynamical electron-phonon coupling. Using first-principles theory as a basis for our calculations, we often go beyond these methods and complement them with many-body perturbation theory. The main aim of this work is to provide a thorough overview of the far-reaching consequences of resorting to the static approximation of electron-lattice interaction...

Dynamical quark loops at low energies and in medium
-
Sanjin Benić
We performed a research of dynamical quark loops as a basis for microscopic modelling of low-energy aspects of Quantum Chromodynamics (QCD). Part of research covers the calculation of the anomalous transition of a virtual photon into three pions, within a constituent quark-meson model. We study the possibility of adding the lowest resonances, e. g. the rho and omega mesons. In the second part mesons are built from quark-antiquark loops (Bethe-Salpeter amplitudes). Quark propagators are...

EFFECT OF METAL(LOID)S ON BIOMARKERS IN BLOOD OF WHITE
STORK (Ciconia ciconia) NESTLINGS FROM CONTINENTAL CROATIA
-
Dora Bjedov
Apex bird species are proven to be relevant bioindicators for assessing environmental
pollutants. To achieve this, the goal of this work was to compare biomarker responses in two
fractions of white stork (Ciconia ciconia) nestling blood; establish novel biomarker approaches
(esterase, fluorescent dyes, metallothioneins), apply previously analysed biomarkers
(glutathione-dependent enzymes); investigate the differences in biomarker responses related to
metal(loid)s in white stork...

EPIGENETIČKE ZNAČAJKE GENA NR3C1 I RAZINA KORTIZOLA U POPULACIJI TRUDNICA NA OTOCIMA I KOPNU
-
Rafaela Mrdjen-Hodžić
Stresna iskustva uključujući i ona doživljena tijekom osjetljivog razdoblja prenatalnog rasta povezuju se s disregulacijom HPA osi, koja rezultira s povišenim razinama kortizola u plazmi. Kohortna studija rođenih na istočnojadranskim otocima (CRIBS) proučava trudnice i njihovu djecu za utvrđivanje ranih odrednica zdravlja i bolesti, koje se javljaju još u fetalnom razdoblju i djetinjstvu. U ovom istraživanju proučeni su antropometrijski parametri majke i djeteta, razina kortizola...

EPR spektroskopija krute trehaloze: utjecaj neuređenosti matrice na dinamiku paramagnetskih centara
-
Iva Šarić
Cilj ovog istraživanja je proučavanje dinamike u materijalima karakteriziranim neuređenošću molekula. Kao prikladan eksperimentalan sustav korištena je trehaloza jer ima najveću temperaturu staklišta, Tg, i najizraženiju mrežu vodikovih veza od svih saharida, zbog čega je zanimljiva za proučavanje niskotemperaturnih anomalija opaženih u staklastom stanju općenito. Prednost primjene elektronske paramagnetske rezonancije (EPR) je u osjetljivosti međudjelovanja spina elektrona i...

Ecology and diversity of cyanobacteria in changing ecosystems in the Eastern Adriatic area
-
Anamarija Kolda
Cyanobacteria are ubiquitous bacteria that evolved photosynthesis and therefore made life on Earth possible
by creating aerobic atmosphere more than 2 billion years ago. As primary colonizers, they have adapted to
diverse types of environments, and primordial as well as actual extreme conditions. In that respect, they are
considered indicators of the ecological properties of the environment in which they are found. This thesis
aims at exploring the vast diversity and ecology of the...

Efekti dvostruke laserske ablacije
-
Nikša Krstulović
U ovome radu proučavan je efekt laserske ablacije dobivene s dva, vremenski korelirana, laserska pulsa. Kao glavni parametar javlja se vrijeme kašnjenja između laserskih pulseva τ, koje je varirano između 0 i 50 μs. Eksperiment se bazira na mjerenju vremenski ovisne apsorpcije, odnosno emisije ablacijskog oblaka titana u vakuumu u ovisnosti o τ. Mjereni su apsorpcijski i emisijski spektri atoma Ti, te emisijski spektri atoma Ti i iona Ti+, te je praćeno njihovo vremensko odvijanje....

Effects of human papillomavirus 16 (HPV16) E6 oncoprotein on cell polarity regulators in head and neck cancers
-
Lucija Lulić
Human papillomaviruses (HPVs) are significant contributors to the global cancer burden by
causing cancers at various anatomical sites, particularly in anogenital and head and neck (HN) area.
A unique E6 feature of all oncogenic HPVs is the ability to target DLG1 and SCRIB proteins which
play roles in the regulation of cell growth and polarity. Their contribution to the onset of HPVinduced HN malignancy is still unknown. Therefore, the potential impact of 16E6 on DLG1 and
SCRIB protein...

Effects of superstructuring on optical and transport properties of selected layered materials
-
Kristijan Velebit
Very special electronic phases brought upon by the superstructuring in layered materials have held the interest of researchers for decades. This thesis deals with the effects of the lattice superstructuring on optical and transport properties of pure and doped samples of 1T-TaS2 and 1T-TiSe2. This work brings the first ever analysis of the optical properties of the nearly-commensurate charge density wave (NCCDW) phase of 1T-TaS2 at temperatures below 200 K. Optical response of the NCCDW...

Efikasni algoritmi za rješavanje robusnih varijanti problema toka u mreži
-
Marko Špoljarec
Cilj doktorskog rada je proučavanje nekoliko novih robusnih varijanti problema toka u mreži koje razlikujemo po obliku polaznog problema (maksimalni tok ili maksimalni tok minimalne cijene) te po nekim osobinama (načinu izražavanja neizvjesnosti u parametrima, stupnju neodređenosti u parametrima ili načinu mjerenja ponašanja zadanog rješenja za zadani scenarij). Za svaku robusnu varijantu cilj je analiziranje njezinih bitnih svojstava, naprimjer računske složenosti, te...
