Fazer maizes zīmola komunikācija: zīmola atpazīstamība maizes lietotāju auditorijā
2016
Darba tēma ir “Fazer” maizes zīmola komunikācija: zīmola atpazīstamība maizes lietotāju auditorijā. Šī darba mērķis ir noskaidrot uzņēmuma “Fazer” maizes zīmola atpazīstamību maizes lietotāju vidū un izpētīt kas to ietekmē. Bakalaura darbs sastāv no trīs daļām - teorētiskās, metodoloģiskās un empīriskās daļas, kā arī secinājumiem. Darba teorētiskais pamatojums balstīts uz literatūru par zīmolvedību, zīmola dzīves ciklu un mārketinga komunikācijām. Pētījuma metodoloģija iekļauj patērētāju aptauju un strukturētu interviju. Pētījuma rezultātā secināts, ka “Fazer” maizes zīmols ieguvis plašu atpazīstamību maizes lietotāju vidū, pateicoties augstajai kvalitātei un plašajam maizes sortimentam, ta…

Effects of adjuvants of the cholera toxin family on CD4 + T cell responses in a murine model of intrarectal immunization with rotavirus-like particles
2011
Mucosal immunization is an important goal of vaccine development to protect against pathogens that use mucosa as portals of entry. However, the use of non-replicating antigens requires the addition of adjuvants.Cholera-like enterotoxins, cholera toxin (CT) from Vibrio cholerae and the heat-labile enterotoxin (LT) from toxinogenic strains of E. coli, as well as the mutant LR-192G and their B subunits (CTB and LTB) have been shown to increase immune responses against unrelated co-administered antigens by mucosal routes. However, their mechanism of action is very complex and not completely understood and differences exist between holotoxins and B subunits and within molecules, differences exis…
Separation of aminoalkanephosphonic acid enantiomers by indirect UV detection capillary electrophoresis with application of cyclodextrins.
2003
Indirect UV detection capillary electrophoresis (CE) was used for the separation of aminoalkanephosphonic acid (AP) enantiomers by applying commercially available cyclodextrins as chiral discriminators. The results show that the separation of the enantiomers depends on pH of the background electrolyte, the molar ratio of cyclodextrin to aminophosphonic acid, and on the type of the applied chiral selector. Optimization of process conditions allowed enantiomeric baseline separation or partial separation of 12 out of 14 alpha-aminophosphonic acids studied. This type of CE might therefore be successfully used for routine determination of enantiomeric purity of aminophosphonic acids.
Ethylammonium hydrogen oxalate–oxalic acid (2/1)
2019
The reaction between ethylamine and oxalic acid in water in a 1:1 molar ratio afforded the title salt, C2H8N+·C2HO4 −·0.5C2H2O4. The hydrogen oxalate anions interact through hydrogen bonding and are organized into a chains propagating along the c-axis direction. The chains are connected to the neighbouring cations and oxalic acid molecules by N—H...O and O—H...O hydrogen bonds and N...O dipole–dipole contacts, leading to a supramolecular three-dimensional network.
Chemical Profile and Biological Activity of Cherimoya (Annona cherimola Mill.) and Atemoya (Annona atemoya) Leaves
2020
Annona cherimola (Cherimoya) and Annona atemoya (Atemoya) are tropical plants known for their edible fruit. Scientific data suggest that their leaves, used in traditional medicine in the form of teas or infusions without evidence of toxicity, contain several bioactive compounds. However, only Annona muricata among all the Annona species is currently used in the nutraceutical field, and its dried leaves are marketed for tea preparation. In this work, we explored the nutraceutical potential of Atemoya and Cherimoya leaves, by evaluating their chemical profile and functional properties. Phytochemical analyses showed large amounts of phenolic compounds, in particular proanthocyanidins, and iden…
Temperature effect on solubility of aroma compounds in various aqueous solutions
2005
International audience; Solubility of nine aroma compounds (methyl ketones, ethyl esters, aldehyde and alcohol) in various aqueous solutions was measured by the mutual solubility method from -10 to +10degreesC. Influence of both, the nature (carbohydrates and polyols) and the substrate concentration (from 0 to 57.5g/100g) on aroma solubility in aqueous solutions was studied. Aroma solubility in water decreased when aroma hydrophobicity increased. Aroma solubility in various aqueous solutions decreased when substrate concentration increased; their solubility was higher in polyols solutions than in polysaccharides ones. Temperature effect on aroma solubility showed a noncontinuous evolution f…
Vides faktoru ietekme uz asaru osmolaritāti
2018
Maģistra darbs ir uzrakstīts latviešu valodā, datorsalikumā uz 55 lapām. Tas satur 3 tabulas, 40 attēlus un 40 atsauces uz literatūras avotiem. Darba mērķis bija novērtēt vides faktoru ietekmi uz asaru osmolaritāti un acs priekšējo struktūru izmeklējumu rezultātiem, kā arī noskaidrot šo parametru savstarpējo mijiedarbību. Pētījums norisinājās 3 daļās, 1. daļā “Aptaujas daļā” piedalījās 125 dalībnieki, 2. daļā “Izmeklējumu daļā” piedalījās 54 dalībnieki un 3. daļa “Atkārtoto mērījumu daļā” piedalījās 21 dalībnieks. Rezultāti parādīja, ka gaisa relatīvais mitrums atstāj ietekmi uz asaru osmolaritāti. Asaru osmolaritāte korelē ar Širmera testa rezultātiem, radzenes krāsošanos un TBUT laiku. Ti…

2021
The molar ratio variations of organic and inorganic reactants of chloridobismuthates(III) with N,N-dimethylethane-1,2-diammonium, [(CH3)2NH(CH2)2NH3]2+, and N,N,N′,N′-tetramethylguanidinium, [NH2C{N(CH3)2}2]+, cations lead to the formation of four different products, namely, tris(N,N-dimethylethane-1,2-diammonium) bis[hexachloridobismuthate(III)], [(CH3)2NH(CH2)2NH3]3[BiCl6]2 (1), catena-poly[N,N-dimethylethane-1,2-diammonium [[tetrachloridobismuthate(III)]-μ-chlorido]], {[(CH3)2NH(CH2)2NH3][BiCl5]} n (2), tris(N,N,N′,N′-tetramethylguanidinium) tri-μ-chlorido-bis[trichloridobismuthate(III)], [NH2C{N(CH3)2}2]3[Bi2Cl9] (3), and catena-poly[N,N,N′,N′-tetramethylguanidinium [[dichloridobismutha…
