Latgaliešu folkloras interpretācija un pētniecība trimdā
2017
Latgaliešu trimdā pēc Otrā pasaules kara ar lielu vērienu tika vākta, apkopota, pētīta folklora, tas bija arī viens no nemainīgi populārākajiem motīviem literatūrā un mākslā visā trimdas periodā no 1945. līdz 1991. gadam, bet līdz šim maz pētīts. Maģistra darba mērķis ir atklāt latgaliešu folkloras interpretācijas īpatnības trimdā, kas ir cieši saistītas ar etnisko identitāti, kā arī izsekot līdzi folkloras vākšanas un pētniecības attīstībai. Vladislava Lōča “Latgaļu izdevnīceibas” paspārnē iznākušajā periodikā, zinātniskajos rakstos un monogrāfijās iespējams izsekot šī procesa attīstībai, bet literatūras un vizuālās mākslas piemēru analīze atklāj tipizētus tēlus, kas funkcionē kā apstiprin…
Grimaces et lèvres pincées : remarques sur la ritualisation pénale (Pascal, Wittgenstein) (Grimaces and Pursed Lips: Remarks on the judicial ritualiz…
2018
Cet article vise à clarifier le recours à une famille de métaphores qui entoure fréquemment le procès (ritualisation, théâtralisation, mise en scène, cérémonie de type religieux), et défend la thèse que la notion de ritualisation judiciaire exprime avant tout la louable intention d'accorder à la justice internationale pénale un temps et des occasions sans finalité préconçue, mais qui permettent la manifestation d'une diversité d'émotions. Il prend principalement appui sur la comparaison des Pensées et des Lettres provinciales de Pascal d'une part, sur le…
Vingrinājumu kopa kaligrāfijas pamatu apguvei profesionālās ievirzes mākslas skolā
2022
Diplomdarba mērķis ir izstrādāt vingrinājumu kopu kaligrāfijas pamatu apguvei, aprobēt un analizēt to, atbilstoši profesionālās ievirzes mākslas skolu programmas prasībām. Lai apgūtu kaligrāfiju, ir jāatpazīst burtu elementi, jāvingrina rokas muskulatūra, jāprot izmantot platgala un asgala instrumentus. Autore piedāvā vingrinājumu kopu dažādu instrumentu un materiālu pielietojumu kaligrāfijas pamatu apguvei. Diplomdarba pirmajā daļā autore skaidro kaligrāfijas jēdzienu un ieskicē kaligrāfijas attīstības gaitu, apraksta kaligrāfiju kā dažādu kultūru sastāvdaļu, min slavenākos kaligrāfus pasaulē un Latvijā, kā arī ieskicē „trīs vaļus”, uz kuriem balstās un kurus pielieto kaligrāfijā: spalvu, …
Co-crystals of an agrochemical active – A pyridine-amine synthon for a thioamide group
2011
Five novel co-crystals of thiophanate-ethyl (TE), an agrochemical active, with di(2-pyridyl)ketone (1), 2-benzoylpyridine (2), 3-benzoylpyridine (3), 4-phenylpyridine (4) and biphenyl (5) were found and crystal structures of four of them (TE1–TE3, TE5) solved by single crystal X-ray diffraction. Three of the co-crystals (TE1–TE3) form by way of a reliable pyridine-amine hydrogen bond synthon and one (TE5) because of close packing effects. The fifth co-crystal was identified by X-ray powder diffraction. The work demonstrates the usage of a reliable supramolecular synthon for crystal engineering, while concurrently reminds that the close packing of even very similar molecules cannot be fully …
Packing incentives and a reliable N–H⋯N–pyridine synthon in co-crystallization of bipyridines with two agrochemical actives
2011
The co-crystallization of agrochemical actives thiophanate-methyl and thiophanate-ethyl with 2,2′-bipyridine, 4,4′-bipyridine and 1,2-bis(4-pyridyl)ethane was investigated with conventional crystallization, the slurry method and liquid-assisted grinding. Co-crystals of both thiophanates with all bipyridines were found and the structures solved with single crystal X-ray diffraction. Whereas the 2,2′-bipyridine co-crystals seem to form because of a combination of weak interactions, and in the case of the thiophanate-methyl, partly because of close packing incentives, the 4,4′-bipyridine and 1,2-bis(4-pyridyl)ethane co-crystals form mainly because of a favourable N–H···N–pyridine hydrogen bond…
N,N-Dimethyl-N-propylpropan-1-aminium chloride monohydrate
2008
The title compound, C8H20N+·Cl−·H2O, has been prepared by a simple one-pot synthesis route followed by anion exchange using resin. In the crystal structure, the cations are packed in such a way that channels exist parallel to the b axis. These channels are filled by the anions and water molecules, which interact via O—H...Cl hydrogen bonds [O...Cl = 3.285 (3) and 3.239 (3) Å] to form helical chains. The cations are involved in weak intermolecular C—H...Cl and C—H...O hydrogen bonds. The title compound is not isomorphous with the bromo or iodo analogues.
3,4,5-Trimethoxy-4'-methylbiphenyl
2013
In the title compound, C16H18O3, the dihedral angle between the benzene rings is 33.4 (2)°. In the crystal, molecules are packed in a zigzag arrangement along the b-axis and are interconnected via weak C—H⋯O hydrogen bonds, and C—H⋯π interactions involving the methoxy groups and the benzene rings of neighbouring molecules.
3,5-Dimethoxy-4'-methylbiphenyl
2013
The title compound, C15H16O2, crystallizes with three independent molecules in the asymmetric unit. The intramolecular torsion angle between the aromatic rings of each molecule are −36.4 (3), 41.3 (3) and −37.8 (3)°. In the crystal, the complicated packing of the molecules forms wave-like layers along the b and c axes. The molecules are connected via extensive methoxy–phenyl C—H…π interactions. A weak C—H…O hydrogen-bonding network also exists between methoxy O atoms and aromatic or methoxy H atoms.
