Salt iodisation is considered a key public health measure for assuring adequate iodine intake in iodine-deficient countries. In Slovenia, the iodisation of all salt was made mandatory in 1953. A considerable regulatory change came in 2003 with the mandatory iodisation of rock and evaporated salt only. In addition, joining the European Union's free single market in 2004 enabled the import of non...
Fuchs, L. 2016. Strain quantifications in different tectonic scales using numerical modelling. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1354. 58 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9513-8. This thesis focuses on calculation of finite and progressive deformation in different tectonic scales using 2D numerical mod...
Introduction: We have shown earlier that the high SO 3 / Cl ratios found in secondary mineral assemblages in shergottite GRIM glasses (Gas-Rich Impact-Melt) likely resulted from interactions of regolith materials with sulfate-rich (and Cl-poor) solutions [1,2]. The low SO 3 /Cl ratios determined in secondary salts in nakhlite fracture-fillings presumably formed by rock interactions with chlorid...
The pressure-induced phase transition in silicon carbide is studied using a constant-pressure ab initio technique. The reversible transition between the zinc-blende structure and the rock-salt structure is successfully reproduced through the simulation. The transformation mechanism at the atomistic level is characterized, and it is found that the transition is based on a tetragonal and an ortho...
Peierls distortion path was proved experimentally for dense ZnO nanoparticles prepared by static compression. Electron irradiation caused rock salt (R) to wurtzite (W) transition, following preferential (111)(R)//(0111)(W); [011](R)//[1213](W) and then transformation strain induced (111)(R)//(1011)(W); [011](R)//[0111](W). The two relationships can be rationalized by specified extent of chair- ...
Increased Rho kinase (ROCK) activity contributes to smooth muscle contraction and regulates blood pressure homeostasis. We hypothesized that potent and selective ROCK inhibitors with novel structural motifs would help elucidate the functional role of ROCK and further explore the therapeutic potential of ROCK inhibition for hypertension. In this article, we characterized two aminofurazan-based i...
the first step in mining activities is rock excavation in both mine development and production. constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...
We present a comprehensive study of the bulk and surface properties of transition metal carbides with rock salt structures and discuss their formation energies and electronic structures. The bonding character of the materials is shown to be dependent on the periodic position of the transition metal as well as the surface termination, which in turn tunes the densities of states and electronic su...

F-center and colloid particle formation have been studied in synthetic NaCl and natural rock salt crystals with apparatus for making optical absorption measurements during irradiation. Fcenter and colloid formation are functions of temperature, dose, dose rate, strain applied prior to irradiation and numerous other factors. Many of the observed properties are in accord with the Jain-Lidiard the...
