Ordering Garside groups
2017
We introduce a condition on Garside groups that we call Dehornoy structure. An iteration of such a structure leads to a left order on the group. We show conditions for a Garside group to admit a Dehornoy structure, and we apply these criteria to prove that the Artin groups of type A and I2(m), m ≥ 4, have Dehornoy structures. We show that the left orders on the Artin groups of type A obtained from their Dehornoy structures are the Dehornoy orders. In the case of the Artin groups of type I2(m), m ≥ 4, we show that the left orders derived from their Dehornoy structures coincide with the orders obtained from embeddings of the groups into braid groups.
Language in Central Europe: An Overview
2009
The linguistic picture of Central Europe, as we know it, started forming in the 6th to 9th centuries. The coming of the Slavs (or rather the spread of their language and way of life to unrelated various ethnic groups) marks the beginning of this caesura that largely closed in 896 AD when the Magyars crossed the Carpathians into Pannonia. This event gradually divided the hypothetically continuous area of Slavic settlement into a southern section, extending from contemporary Slovenia to Bulgaria, and into a northern section, which coincided with the areas from the Elbe in today’s eastern Germany to the upper Volga in northeastern Russia. In the west, the Magyar-speakers skirted the East and …
The Antarctic yeast Candida sake: Understanding cold metabolism impact on wine
2017
Current winemaking trends include low-temperature fermentations and using non-Saccharomyces yeasts as the most promising tools to produce lower alcohol and increased aromatic complexity wines. Here we explored the oenological attributes of a C. sake strain, H14Cs, isolated in the sub-Antarctic region. As expected, the cold sea water yeast strain showed greater cold growth, Na+-toxicity resistance and freeze tolerance than the S. cerevisiae QA23 strain, which we used as a commercial wine yeast control. C. sake H14Cs was found to be more sensitive to ethanol. The fermentation trials of low-sugar content must demonstrated that C. sake H14Cs allowed the cold-induced lag phase of growth to be el…
Paaudžu problēmas Gētes jaunā Vērtera ciešanās un Plencdorfa Jaunā Vērtera jaunās ciešanas
2018
Maģistra darba tēma ir paaudžu problēmas Johana Volfganga fon Gētes romānā ''Jaunā Vertera ciešanas'' un Ulriha Plencdorfa ''Jaunā V. jaunās ciešanas'', pamatojoties uz šo divu darbu salīdzinājumu. Maģistra darba pirmajā daļā ir apskatītas Gētes un Plencdorfa biogrāfijas, lai saprastu, kas stāv aiz šiem bestselleriem. Tālāk abi autori tiek izskatīti kā viņu laika pārstāvji, proti, Gēte kā 18. gadsimta pārstāvis un Plencdorfs kā 20. gadsimta pārstāvis. Analizējot šo tēmu, atklājas, ka abas grāmatas bija ļoti populāras lasītāju vidū, taču valdības un tās pārstāvju viedoklis nebija pozitīvs. Darba otrajā daļā ir apskatīti vēsturiski notikumi Gētes dzīves laikā un pirms grāmatas sastādīšanas, t…
Stereoselective Access to Fluorinated and Non-fluorinated Quaternary Piperidines: Synthesis of Pipecolic Acid and Iminosugar Derivatives
2012
The preparation of optically pure quaternary piperidines, both fluorinated and non-fluorinated, has been achieved from a chiral imino lactone derived from (R)-phenylglycinol. In the case of the fluorinated derivatives, the addition of (trifluoromethyl)trimethylsilane (TMSCF(3)) followed by iodoamination and migration of the CF(3) group allowed access to four derivatives of α-(trifluoromethyl)pipecolic acid. A theoretical study of the CF(3)-group rearrangement has been carried out to help establish the reaction mechanism of this uncommon transformation. Moreover, a route to trifluoromethyl-substituted iminosugars was also developed through the diastereoselective dihydroxylation of suitable s…
Nishadana typica (Distant, 1889) (Hemiptera: Heteroptera: Cydnidae): first record from Laos
2016
Nishadana typica Distant, 1889 (Hemiptera: Heteroptera: Cydnidae) is reported for the first time from Laos. This species was hitherto recorded only in India (three localities), Myanmar (a single locality), and Bangladesh (general data, without closer location).
A cytochemical study on the effects of energy deprivation on autophagocytosis in Ehrlich ascites tumor cells
1988
The effect of energy deprivation on autophagocytosis in Ehrlich ascites tumor cells was studied using cytochemical techniques. Autophagocytosis was induced with vinblastine incubation (0.1 mM) and the cellular ATP-level was lowered with 2-deoxy-D-glucose (0.35 mM). Acid phosphatase was used as a marker for lysosomal enzymes and imidazole-buffered osmium tetroxide impregnation in order to study the effects of energy deprivation on the maturation of autophagic vacuole (AV) membranes. Control and vinblastine treated cells maintained their ATP-levels throughout the incubation period tested (120 min). 2-Deoxy-D-glucose alone and with vinblastine decreased the intracellular ATP-level significantl…
Solutions properties and solute–solvent interactions in ternary sugar–salt–water solutions
2010
International audience; Viscometric constants were used to provide information on solute-solvent interactions in ternary water-sugar-salt solutions. Comparison was made between pure water and aqueous salt solution as solvents affecting the behaviour of small carbohydrates. The determination of intrinsic viscosity was made more accurate by applying triple extrapolation of the three equations (Huggins. Kramer and Meffroy-Biget). Results obtained with this triple extrapolation method were compared to that obtained with the Jones-Dole equation usually used. The B coefficient of the Jones-Dole equation was interpreted in terms of its components (B(size)) and (B(structure)), respectively assigned…
