Karjeras vadība vispārizglītojošo skolu 8. - 9. klašu skolēnu profesionālās pašnoteikšanās veicināšanai
2017
Maģistra darba “Karjeras vadība vispārizglītojošo skolu 8.-9. klašu skolēnu profesionālās pašnoteikšanās veicināšanai” mērķis ir noteikt, kā karjeras vadība uzlabos skolēnu profesionālo pašnoteikšanos. Maģistra darba pētījuma jautājums - veiksmīga karjeras izglītība veicina skolēnu pašnoteikšanos. Darba teorētisko daļu veido literatūras avotu analīze par karjeras izglītības vadību, izpēti, analīzi un rezultātiem. Praktiski pētnieciskajā daļā tika izpētīti karjeras izglītības veicināšanu ietekmējošo faktoru attīstīšana. Uz pētījuma bāzes tiek salīdzināti divu skolu karjeras izglītības rezultāti, kur vienā tiek īstenota karjeras izglītības programma un otrā netiek īstenota karjeras izglītības…
Priekšnoteikumi pilnīgam atbrīvojumam no naudas soda Latvijas konkurences tiesībās
2015
Sacensība starp tirgus dalībniekiem kļūst arvien asāka. Lai veiksmīgi spētu konkurēt mūsdienu blīvajā tirgū, komersanti meklē jaunus risinājumus un strādā pie stratēģijām, kas varētu nodrošināt pēc iespējas lielāku peļņu. Tomēr dažreiz viena tirgus līmeņa dalībnieki savā starpā vienojas par sadarbību, kas vērsta pret konkurenci, ar mērķi gūt lielāku peļņu, piemēram, tirgus un klientu sadali, cenu noteikšanu, kārtību, kādā tie piedalās publiskos iepirkumos, informācijas izpaušanu utt., novēršot savstarpēju konkurenci. Ņemot vērā, ka šādas aizliegtās vienošanās pārkāpums, tieši karteļa gadījumos, ir uzskatāmas par smagākajiem konkurences noteikumu pārkāpumiem, Konkurences padomes pienākums ir…
The S … Hal and Se … Hal chalcogen bonding in a series of thiourea, selenourea and their derivatives
2021
The chalcogen bonding (ChB) in a series of thiourea, selenourea and their derivatives has been investigated in the present paper. Thus, selenourea and dimethylselenourea undergo dimerization and trimerization processes in the presence of various halogen species (1–5). Selenourea and dimethylselenourea form trimers 3–4 in the presence of lighter halogens (chlorine and bromine) through Se⋯Se chalcogen bonding. When moving to heavier halogen (iodine), the dimers 1–2 are formed. Thiourea and its derivatives also tend to make very strong S⋯S bonds and form dimers in the case of lighter halogens chlorine and bromine (compounds 6–7). However, the monomers separated by the iodine species are formed…
Rapid self-healing and anion selectivity in metallosupramolecular gels assisted by fluorine-fluorine interactions.
2017
Simple ML2 [M = Fe(II), Co(II), Ni(II)] complexes obtained from a perfluoroalkylamide derivative of 4-aminophenyl-2,2′,6,2′-terpyridine spontaneously, yet anion selectively, self-assemble into gels, which manifest an unprecedented rapid gel strength recovery, viz. self-healing, and thermal rearrangement in aqueous dimethyl sulfoxide. The key factor for gelation and rheological properties emerges from the fluorine–fluorine interactions between the perfluorinated chains, as the corresponding hydrocarbon derivative did not form metallogels. The perfluoro-terpyridine ligand alone formed single crystals, while its Fe(II), Co(II) or Ni(II) complexes underwent rapid gelation leading to highly enta…
FTIR matrix isolation and theoretical studies of glycolic acid dimers
2018
Glycolic acid (GA) dimers were studied in low temperature argon matrices by means of FTIR spectroscopy. Experimentally, the dimers were produced when monomeric glycolic acid molecules were thermally mobilized upon annealing of argon matrices at 25–35 K. The experimental spectra observed upon annealing indicate the presence of three different dimer structures. Computationally, MP2 and DFT calculations were used to study the potential dimer species in order to scrutinize the possible dimer structures, their energetics and their spectral features. Altogether 27 local minima were found for dimer structures for the three lowest conformers of glycolic acid considered based on previous studies on …
Deterministic Modification of CVD Grown Monolayer MoS2 with Optical Pulses
2021
| openaire: EC/H2020/820423/EU//S2QUIP | openaire: EC/H2020/834742/EU//ATOP Transition metal dichalcogenide monolayers have demonstrated a number of exquisite optical and electrical properties. Here, the authors report the optical modification of topographical and optical properties of monolayer MoS2 with femtosecond pulses under an inert atmosphere. A formation of three-dimensional structures on monolayer MoS2 with tunable height up to ≈20 nm is demonstrated. In contrast to unmodified monolayer MoS2, these optically modified structures show significantly different optical properties, such as lower photoluminescence intensity and longer fluorescence lifetime. The results suggest a novel way…

Tribological properties of thin films made by atomic layer deposition sliding against silicon
2018
Interfacial phenomena, such as adhesion, friction, and wear, can dominate the performance and reliability of microelectromechanical (MEMS) devices. Here, thin films made by atomic layer deposition (ALD) were tested for their tribological properties. Tribological tests were carried out with silicon counterpart sliding against ALD thin films in order to simulate the contacts occurring in the MEMS devices. The counterpart was sliding in a linear reciprocating motion against the ALD films with the total sliding distances of 5 and 20 m. Al2O3 and TiO2 coatings with different deposition temperatures were investigated in addition to Al2O3-TiO2-nanolaminate, TiN, NbN, TiAlCN, a-C:H [diamondlike car…
