Smaller calcite lattice deformation caused by occluded organic material in coccoliths than in mollusk shell.
2015
7 pages; International audience; The growth and nucleation of biominerals are directed and affected by associated biological molecules. In this paper, we investigate the influence of occluded biomolecules on biogenic calcite from the coccolithophorid Pleurochrysis carterae and from chalk, a rock composed predominantly of fossil coccoliths. We compare the results with data on chalk from the extensively studied mussel Pinna nobilis that served as a control. Using high resolution synchrotron powder X-ray diffraction combined with in situ heating, the influence of organic compounds on the structure of the inorganic phase was probed. Two heating cycles allow us to differentiate the effects of th…
Crystallized nano-sized alpha-tricalcium phosphate from amorphous calcium phosphate: microstructure, cementation and cell response
2015
New insight on the conversion of amorphous calcium phosphate (ACP) to nano-sized alpha tricalcium phosphate (α-TCP) provides a faster pathway to calcium phosphate bone cements. In this work, synthesized ACP powders were treated with either water or ethanol, dried, crystallized between 700 and 800 °C, and then cooled at different cooling rates. Particle size was measured in a scanning electron microscope, but crystallite size calculated by Rietveld analysis. Phase composition and bonding in the crystallized powder was assessed by x-ray diffraction and Fourier-transform infrared spectroscopy. Results showed that 50 nm sized α-TCP formed after crystallization of lyophilized powders. Water trea…
Par emigrācijas (no Liepājas uz Kanādu) demogrāfisko ietekmi laika posmā no 1906. līdz 1914. gadam
2021
Darbā tiek apskatīta emigrācijas plūsma no Krievijas Impērijas uz Kanādu caur Libau (mūsdienās – Liepāju) ostu laika posmā no 1906. – 1914. gadam, kad starp Libau un Ziemeļameriku bija tieša jūras ceļu satiksme. Pētījuma pamatā ir oriģinālie kuģniecības manifesti, kas tiek salīdzināti un pretstatīti akadēmiskajiem pētījumiem par dažādām emigrantu grupām Kanādā. Pieejamie dati par galvenajām etniskajām grupām astoņu gadu posmā tiek salīdzināti, pretstatīti un papildināti ar aptaujāto emigrantu, kas emigrējuši no Krievijas Impērijas uz Kanādu šajā laika posmā, pēcteču teikto un Libau ostas apstākļu analīzi šīs emigrācijas laikā, kas balstīta šī laika krievu, britu, amerikāņu, ebreju un latvie…
Den kultur- och litteraturhistoriska gestalten i den lettiska novellen “Svētā Briģita” (“Heliga Birgitta”) av Jānis Ezeriņš
2019
Cultural-historical and literary gestalt in the Latvian short story “Saint Birgitta” (“Heliga Birgitta”) by Jānis EzeriņšThe Latvian author Jānis Ezeriņš’s (1891–1924) literary heritage includes, among other texts, the collection of short stories Fantastiska novele un citas (Fantastic short story and others, 1923). The collection contains the short story “Svētā Briģita” (“Saint Birgitta”), in which the author has used the image of a saint, which is very well known in the history of culture, literature and religion. The image can be related both to Celtic mythology and the historical Swedish personality, who had been the founder of Vadstena monastery and a literary author herself (approx. 13…
