Sociālās kompetences veidošanās procesa vadība pirmsskolas izglītības iestādē
2021
Maģistra darba pētījuma tēma ir “Sociālās kompetences veidošanās procesa vadība pirmsskolas izglītības iestādē”. Pētījuma mērķis ir izpētīt sociālās kompetences veidošanās procesu un tā vadību X pirmsskolā. Pētījums izstrādāts, pamatojoties uz zinātnisko rakstu, pirmsskolas normatīvo aktu analīzi, starptautisku un Latvijā veiktu projektu analīzi, pedagogu, izglītības vadītāju un psihologu atziņām. Maģistra darbs ietver 3 nodaļas. 1. nodaļā analizēta sociālās kompetences būtība, modeļi un elementi, sociālās kompetences attīstība izglītībā. 2. nodaļā analizēta sociālās kompetences veidošanās specifika pirmsskolā, skaidrojot tās ietekmējošos faktorus un procesa vadību. 3. nodaļā apkopoti un an…
Représentations socio-professionnelles des étudiant·es en soins infirmiers : effets du genre
2022
Les étudiant·es infirmier·es sont majoritairement des femmes. L’objet de notre travail est, simultanément, de modéliser la représentation socioprofessionnelle qu’ont les étudiant·es infirmier·es de leur futur métier, d’en analyser l’ancrage et l’impact du genre. À partir d’une méthode d’évocation par induction hiérarchisée et d’entretiens semi-directifs, des différences associées au genre apparaissent dans la structure de la représentation, plus consensuelle chez les femmes. Les variations concernent également les qualités vues comme nécessaire pour être un·e bon·ne infirmier·e. Enfin, la motivation initiale, le parcours de formation antérieur ou encore les projections professionnelles sont…
Combined Use of Structure Analysis, Studies of Molecular Association in Solution, and Molecular Modelling to Understand the Different Propensities of…
2021
The arrangement of hydroxyl groups in the benzene ring has a significant effect on the propensity of dihydroxybenzoic acids (diOHBAs) to form different solid phases when crystallized from solution. All six diOHBAs were categorized into distinctive groups according to the solid phases obtained when crystallized from selected solvents. A combined study using crystal structure and molecule electrostatic potential surface analysis, as well as an exploration of molecular association in solution using spectroscopic methods and molecular dynamics simulations were used to determine the possible mechanism of how the location of the phenolic hydroxyl groups affect the diversity of solid phases formed…
Development of microfluidics for sorting of carbon nanotubes
2018
Sorting of carbon nanotubes by their chirality is the current bottleneck in the way to their broad employment based on their exceptional electronic and optical properties. Despite the extensive effort, there is no known method, which would result in really pure chirality ensembles. Previously reported sorting protocols result in enrichment rather than in sorting, alter electronic structure, and suffer from low yield. This is mostly due to the statistical approach, where the nanotubes with mixed chiralities are treated as a set. In this thesis, we propose a new sorting technique based on nanotube-by-nanotube compartmelization, characterization, and sorting in a continuously running droplet-b…
A Theoretical and Experimental Investigation of the Spectroscopic Properties of a DNA-Intercalator Salphen-Type ZnIIComplex
2014
The photophysical and DNA-binding properties of the cationic zinc(II) complex of 5-triethylammonium methyl salicylidene ortho-phenylenediiminato (ZnL 2 + ) were investi- gated by a combination of experimental and theoretical methods. DFT calculations were performed on both the ground and the first excited states of ZnL 2 + and on its possi- ble mono- and dioxidation products, both in vacuo and in selected solvents mimicked by the polarizable continuum model. Comparison of the calculated absorption and fluores- cence transitions with the corresponding experimental data led to the conclusion that visible light induces a two-elec- tron photooxidation process located on the phenylenediimi- nato…
The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST)
2007
(abridged:) The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) surveys the most populated ~5 square degrees of the Taurus star formation region, using the XMM-Newton X-ray observatory to study the thermal structure, variability, and long-term evolution of hot plasma, to investigate the magnetic dynamo, and to search for new potential members of the association. Many targets are also studied in the optical, and high-resolution X-ray grating spectroscopy has been obtained for selected bright sources. The X-ray spectra have been coherently analyzed with two different thermal models (2-component thermal model, and a continuous emission measure distribution model). We present ov…
The close classical T Tauri binary V4046 Sgr: Complex magnetic fields & distributed mass accretion
2011
We report here the first results of a multi-wavelength campaign focussing on magnetospheric accretion processes within the close binary system V4046 Sgr, hosting two partly-convective classical T Tauri stars of masses ~0.9 Msun and age ~12 Myr. In this paper, we present time-resolved spectropolarimetric observations collected in 2009 September with ESPaDOnS at the Canada-France-Hawaii Telescope (CFHT) and covering a full span of 7d or ~2.5 orbital/rotational cycles of V4046 Sgr. Small circularly polarised Zeeman signatures are detected in the photospheric absorption lines but not in the accretion-powered emission lines of V4046 Sgr, thereby demonstrating that both system components host lar…
Spectral analysis of the dipping LMXB system XB 1916-053
2019
Context: XB 1916-053 is a low mass X-ray binary system (LMXB) hosting a neutron star (NS) and showing periodic dips. The spectrum of the persistent emission was modeled with a blackbody component having a temperature between 1.31 and 1.67 keV and with a Comptonization component with an electron temperature of 9.4 keV and a photon index $\Gamma$ between 2.5 and 2.9. The presence of absorption features associated with highly ionized elements suggested the presence of partially ionized plasma in the system. Aims: In this work we performed a study of the spectrum of XB 1916-053, which aims to shed light on the nature of the seed photons that contribute to the Comptonization component. Methods: …
