Ion beam analysis of geometrically structured samples

Author(s): David Jezeršek (Author), Žiga Šmit (Supervisor)

Year: 2011

Type: Doctoral dissertation

An experimental set-up for the detection of scattered projectile ions was constructed at the external (in air) beamline of the Microanalytical Center at the Jožef Stefan Institute. The system is composed of a detector for the analysis of back-scattered projectiles, casually called the RBS detector, a precise positioning system and …

Model for Monitoring and Assessment of a Public Health Care Network

Author(s): Aleksander Pur (Author), Marko Bohanec (Supervisor)

Year: 2011

Type: Doctoral dissertation

It is hard to imagine the management of any system without monitoring it as a process of continuously gathering data and performing real-time analyses. In general, monitoring can improve the estimation of the current state, optimization of the business processes, identification of the critical elements and new opportunities, and prediction …

Synthesis and Characterization of Aluminium Foams

Author(s): Irena Paulin (Author), Monika Jenko (Supervisor)

Year: 2011

Type: Doctoral dissertation

Aluminium foams are prospective class of cell materials that offer a variety of applications in fields such as lightweight structures or crash-energy management. Due to interesting combination of physical and mechanical properties, such as high stiffness at low density, high impact energy absorption, flame and heat resistance, sound absorption, aluminium …

Nitrate migration in plant-soil-groundwater system

Author(s): Martina Šturm (Author), Sonja Lojen (Supervisor)

Year: 2011

Type: Doctoral dissertation

Nitrogen (N) is an essential nutrient for plant growth and one which has the greatest effect on the yield. Since effective indigenous sources are insufficient by far to support current levels of global agricultural outputs, N is intensively applied by farmers in the form of N-based fertilisers. However, excessive rates …

Development of analytical methods for speciation of organotin compounds in environmental samples using gas chromatography and mass spectrometry

Author(s): Mitja Vahčič (Author), Janez Ščančar (Supervisor)

Year: 2011

Type: Doctoral dissertation

Organotin compounds (OTCs) are the organometallic compounds with the most numerous applications. Today, it is more than 50 years of their intensive development and use. While they are highly useful chemicals they are also extremely toxic to a wide array of aquatic and terrestrial living organisms at very low concentrations. …

Ensembles for predicting structured outputs

Author(s): Dragi Kocev (Author), Sašo Džeroski (Supervisor)

Year: 2011

Type: Doctoral dissertation

In this thesis, we address the task of learning models for predicting structured outputs, which take as input a tuple of attribute values and produce as output a structured object. In contrast to classification and regression, where the output is a single scalar value, in our case the output is …

Migration of critical radionuclides in the area of former uranium mine Žirovski vrh

Author(s): Marko Štrok (Author), Borut Smodiš (Supervisor)

Year: 2011

Type: Doctoral dissertation

A study of the migration of critical radionuclide in the area of the former uranium mine of Žirovski vrh in Slovenia was performed. Critical natural radionuclides are defined as the long-lived natural radionuclides from the uranium-radium decay chain, which are 238U, 234U, 230Th, 226Ra, 210Pb and 210Po. In the area …

The synthesis and characterization of glass–ceramics based on ternary system MgO-B2O3-SiO2

Author(s): Urban Došler (Author), Danilo Suvorov (Supervisor), Marjeta Maček Kržmanc (Co-Supervisor)

Year: 2011

Type: Doctoral dissertation

The past fifteen years has seen the rapid development of various wireless communication devices, which operate at microwave or milimeterwave frequencies (mobile phones, wireless local-area networks (LAN), Bluetooth, etc.). At the same time, this progress has stimulated the development of new materials and process technologies, which enable the size reduction …

Selenocompounds in selenium-enriched plants determined by spectrometric methods

Author(s): Petra Cuderman (Author), Vekoslava Stibilj (Supervisor)

Year: 2010

Type: Doctoral dissertation

Selenium (Se) has been demonstrated to be an essential trace element for maintenance of animal and human health. Se is incorporated into proteins to make selenoproteins, which are important antioxidant enzymes. The antioxidant properties of selenoproteins help to prevent cellular damage caused by radicals. Radicals are natural by-products of oxygen …

Occurrence, fate and removal of pharmaceutical residues in water treatment

Author(s): Tina Kosjek (Author), Ester Heath (Supervisor)

Year: 2009

Type: Doctoral dissertation

The presence of pharmaceutical residues in surface waters is an emerging environmental issue that provides a new challenge to treatment systems for potable water, wastewater and water reuse. Their principle pathways into the sewerage system are twofold: first, after being administered to patients they are normally excreted as various metabolites …
