This dissertation presents an edition of six poems from John Donne’s Songs and Sonets—“The Indifferent,” “Love’s Usury,” “The Will,” “The Funerall,” “The Primerose,” and “The Dampe”—and a digital edition of one additional poem, “To His Mistress Going to Bed.” Using the methodologies of The Variorum Edition of the Poems of John Donne, I have also adopted the edition’s principal goal—to recover and present Donne’s exact texts to the extent that this is possible. For each poem, I have selected a copy-text and emended it in accordance with the Variorum’s principles. A textual introduction for each poem explains how the copy-text was chosen and traces the circulation of the text in all seventeenth-century artifacts. I have also provided a textual apparatus for each poem, which, in addition to recording the texts collated, emendations to the copy-text, imperfections in the sources, and indentation patterns in the sources, also notes all verbal variants and variants of punctuation. Finally, I have created a stemma charting the transmissional history for each poem and giving a visual representation of how the textual artifacts relate to each other. The other major component of my dissertation, a digital edition of “To His Mistress Going to Bed,” is meant to serve as a prototype for what might usefully be done with Donne’s poems in a digital medium. While the actual digital edition of this poem cannot be fully represented on paper, my chapter on this edition outlines the process I used to create it and describes its major features. The digital edition itself can be found at <http://donnevariorum.tamu.edu/resources/tohismistress/tohismistress.html>.

This master‘s thesis studies problems of chosen active substances in cosmetic emulsions and gels. There is their main characteristics – distribution and properties of cosmetic emulsions and gels, preparation of the active substances, effects on the skin and conditions, which could them influence. In experimental part, preparation of gels and emulsions bases was described which were than enriched by active substances - evening primrose oil, hemp oil, Salvia officinalis extract, Symphytum officinale extract and sea salt. Properties of these cosmetic gels and emulsions bases with the addition of active substances depend on temperature and method of storage, amount of light exposure, method of preparation and another conditions. Action of these factors can cause changes of the stability, thereby the cosmetics effects on the skin can be lost. On the bases of performed rheology measurements (oscillation and flow measurements), pH measurements and sensory analysis were determined, if the properties of examined samples were changed. The measurement was performed in the certain time intervals and the properties were evaluated like at laboratory temperature 23±2 °C, so after exposure to temperature regime 37 °C in thermoregulator. On the basis of performed measurements, there was determined, that gel base with addition of Symphytum officinale extract had the most stability properties.
