3. Infrared spectra in amorphous aluminaLuigi Giacomazzi, Nikita S Shcheblanov, Mikhail E Povarnitsyn, Yanbo Li, Andraž Mavrič, Barbara Zupančič, Jože Grdadolnik, Alfredo PasquarelloOpis: We present a combined study based on experimental measurements of infrared (IR) dielectric function and first-principles calculations of IR spectra and vibrational density of states (VDOS) of amorphous alumina (am-Al₂O₃). In particular, we show that the main features of the imaginary part of the dielectric function ε₂(ω) at ~380 and 630 cm-¹ are related to the motions of threefold coordinated oxygen atoms, which are the vast majority of oxygen atoms in am-Al₂O₃. Our analysis (involving three model structures) provides an alternative point of view with respect to an earlier suggested assignment of the vibrational modes, which relates them to the stretching and bending vibrational modes of AlOₙ (n = 4, 5, and 6) polyhedra. Our assignment is based on the additive decomposition of the VDOS and ε₂(ω) spectra, which shows that: (i) the band at ~380 cm-¹ features oxygen motions occurring in a direction normal to the plane defined by the three nearest-neighbor aluminum atoms, i.e. out-of-plane motions of oxygen atoms; (ii) Al-O stretching vibrations (i.e. in-plane motions of oxygen atoms) appear at frequencies above ~500 cm-¹, which characterize the vibrational modes underlying the band at ~630 cm-¹.

4. Antibacterial activity of seed extracts of Okra (Abelmoschus esculentus) against selected pathogenSandra Oloketuyi, 2017 Opis: The aim of the study was to determine the antibacterial potency of aqueous and ethanoic extracts of Abelmoschus esculentus seeds. Antibacterial activity of aqueous and ethanoic extracts of A. esculentus seeds were evaluated against selected foodborne pathogens; Listeria monocytogenes, Bacillus cereus, Salmonella enterica, Staphylococcus aureus and Escherichia coli) using agar well diffusion method by measuring the clear zone of inhibition diameter in (mm). It was observed that the aqueous and ethanoic extracts of the four samples of A. esculentus seeds showed broad range of inhibitory activity against the test bacteria especially L. monocytogenes. Thus, A. esculentus seed has a great potential as effective antilisterial and antibacterial activity. Practical Application: Consumption of okra seeds is highly recommended for its nutritive value and antibacterial activity against pathogens, which are most commonly attributed to foodborne diseases such as listeriosis, diarrhea, and salmonellosis. Also, further study could be conducted by isolating and identifying the active ingredient responsible for antibacterial potency for pharmaceutical purpose.

6. Insight into the interdependence of Ni and Al in bifunctional Ni/ZSM-5 catalysts by Ni K-edge XAS analysisIztok Arčon, Vu Hue-Tong, Goran Dražić, Janez Volavšek, Gregor Mali, Nataša Zabukovec Logar, Nataša Novak Tušar, 2023 Opis: Catalyst design is crucial for improving catalytic activity and product selectivity. In a bifunctional Ni/ZSM-5
zeolite type catalyst, catalytic properties are usually tuned via varying Al and Ni contents [1]. While changes in
acid properties associated with Al sites are usually closely investigated, Ni phases, however, receive inadequate
attention. Herein, we present a systematic structural study of Ni in the Ni/ZSM-5 materials by Ni K-edge
XANES (X-ray absorption near edge structure) and EXAFS (extended X-ray absorption fine structure) analyses,
to monitor the local structure and chemical state of Ni species in the catalysts. In combination with XRD and
TEM we resolved the changes in the local environment of Ni species induced by the different Al contents of
the parent ZSM-5 prepared by a “green”, template free technique [2].
Ni species in Ni/ZSM-5 exist as NiO crystals (3–50 nm) and as charge compensating Ni2+ cations. The Ni Kedge
XANES and EXAFS results enabled the quantification of Ni-containing species. At a low Al to Si ratio
(nAl/nSi < 0.04), the NiO nanoparticles predominate in the samples and account for over 65% of Ni phases.
However, NiO is outnumbered by Ni2+ cations attached to the zeolite framework in ZSM-5 with a high Al to Si
ratio (nAl/nSi = 0.05) due to a higher number of framework negative charges imparted by Al. The obtained
results show that the number of highly reducible and active NiO crystals is strongly correlated with the
framework Al sites present in ZSM-5 zeolites, which depend greatly on the synthesis conditions. Therefore,
this kind of study is beneficial for any further investigation of the catalytic activities of Ni/ZSM-5 and other
metal-modified bifunctional catalysts.

8. Priložnosti za mlade ustvarjalce animiranih filmov v EvropiMiha Reja, 2023 Opis: Diplomska naloga je razdeljena na tri dele. Prvi del opisuje priložnosti, kot so delavnice in umetniške rezidence za mlade ustvarjalce na področju animiranega filma v Evropi. V tem delu bom razjasnil pomen delavnic in umetniških rezidenc ter njun namen. Predstavil bom primere delavnic in rezidenc, katerih sem se udeležil, ter vključil lastno refleksijo. Poudaril bom delavnico DSAF Inkubator, Animation Sans Frontières, CEE Rise & Shine ter scenaristično delavnico Kratka Scena. Prvi del bom zaključil s predstavitvijo umetniške rezidence Open Workshop.
V drugem delu se bom poglobil v filmske festivale in animacijske forume. To so izkušnje, ki so predvsem osredotočene na mreženje. Predstavil bom dva največja animacijska foruma v Evropi, CEE Animation Forum in Cartoon Forum. Sledila bo predstavitev svetovno znanih festivalov animiranega filma, kot sta Annecy in Animafest Zagreb, ter festivalov v Sloveniji, kot sta Animateka in StopTrik. Poglavje o festivalih se zaključi z omembo ostalih pomembnih festivalov v Evropi.
V tretjem delu se bom osredotočil na praktični del diplomskega dela, kratki animirani film Kurent. To poglavje je razdeljeno na štiri dele: predprodukcijo, produkcijo, postprodukcijo in dosežke. V predprodukciji bom razjasnil, od kod izhaja ideja. V produkciji se bom poglobil v ustvarjalni proces filma. V postprodukciji bom predstavil sodelovanje z dvema postprodukcijskima hišama (NuFrame in Zvokarna). Nalogo bom zaključil z dosežki filma. S tem bom povezal vse tri dele in tvoril celoto.

9. The Monitoring, Logging, and Alarm system for the Cherenkov Telescope ArrayAlessandro Costa, Saptashwa BHATTACHARYYA, Barbara MARČUN, Judit PÉREZ ROMERO, Samo Stanič, Veronika VODEB, Serguei Vorobiov, Gabrijela ZAHARIJAS, Marko Zavrtanik, Danilo Zavrtanik, Miha ŽIVEC, 2021 Opis: We present the current development of the Monitoring, Logging and Alarm subsystems in the framework of the Array Control and Data Acquisition System (ACADA) for the Cherenkov Tele-scope Array (CTA). The Monitoring System (MON) is the subsystem responsible for monitoring and logging the overall array (at each of the CTA sites) through the acquisition of monitoring and logging information from the array elements. The MON allows us to perform a systematic approach to fault detection and diagnosis supporting corrective and predictive maintenance to minimize the downtime of the system. We present a unified tool for monitoring data items from the telescopes and other devices deployed at the CTA array sites. Data are immediately available for the operator interface and quick-look quality checks and stored for later detailed inspection. The Array Alarm System (AAS) is the subsystem that provides the service that gathers, filters, exposes, and persists alarms raised by both the ACADA processes and the array elements su-pervised by the ACADA system. It collects alarms from the telescopes, the array calibration, the environmental monitoring instruments and the ACADA systems. The AAS sub-system also creates new alarms based on the analysis and correlation of the system software logs and the status of the system hardware providing the filter mechanisms for all the alarms. Data from the alarm system are then sent to the operator via the human-machine interface.

10. Exploring the population of Galactic very-high-energy γ-ray sourcesConstantin Steppa, Saptashwa BHATTACHARYYA, Barbara MARČUN, Judit PÉREZ ROMERO, Samo Stanič, Veronika VODEB, Serguei Vorobiov, Gabrijela ZAHARIJAS, Marko Zavrtanik, Danilo Zavrtanik, Miha ŽIVEC, 2021 Opis: At very high energies (VHE), the emission of γ rays is dominated by discrete sources. Due to the limited resolution and sensitivity of current-generation instruments, only a small fraction of the total Galactic population of VHE γ-ray sources has been detected significantly. The larger part of the population can be expected to contribute as a di˙use signal alongside emission originating from propagating cosmic rays. Without quantifying the source population, it is not possible to disentangle these two components. Based on the H.E.S.S. Galactic plane survey, a numerical approach has been taken to develop a model of the population of Galactic VHE γ-ray sources, which is shown to account accurately for the observational bias. We present estimates of the absolute number of sources in the Galactic Plane and their contribution to the total VHE γ-ray emission for five di˙erent spatial source distributions. Prospects for CTA and its ability to constrain the model are discussed. Finally, first results of an extension of our modelling approach using machine learning to extract more information from the available data set are presented.
