Practical significance of relative assimilable nitrogen requirements of yeast: a preliminary study of fermentation performance and liberation of H(2)S
No full textThe definitive version is available at www.blackwell-synergy.com Article first published online: 12 MAR 2008Saccharomyces cerevisiae wine yeast strains AWRI 796 and AWRI 835, representing a high and a low nitrogen-requiring strain respectively, were cultured in media of varying nitrogen (ammonium) content. Ammonium utilisation, biomass yield, fermentation progress and the liberation of hydrogen sulfide were monitored. Findings from this study support the original classification of these strains in terms of their relative requirement for nitrogen. Accordingly, when compared with AWRI 835 grown under the same conditions, the high nitrogen-requiring strain, AWRI 796, removed c. 8% more nitrogen from the medium, produced c. 7 to 13% more biomass, failed to complete fermentation in the time frame of the experiment and liberated hydrogen sulfide in greater amounts and/or over longer periods. These findings confirm that measures of relative nitrogen requirement form an extremely useful parameter by which to select strains that are better suited to the problem-free fermentation of musts of low nitrogen content.Jennifer M.

Rapid method for proline determination in grape juice and wine
No full textProline is typically the most abundant amino acid present in grape juice and wine. The amount present is influenced by viticultural and winemaking factors and can be of diagnostic importance. A method for rapid routine quantitation of proline would therefore be of benefit for wine researchers and the industry in general. Colorimetric determination utilizing isatin as a derivatizing agent has previously been applied to plant extracts, biological fluids, and protein hydrolysates. In the current study, this method has been successfully adapted to grape juice and wine and proved to be sensitive to milligram per liter amounts of proline. At sugar concentrations above 60 g/L, interference from the isatin-proline reaction was observed, such that proline concentrations were considerably underestimated in grape juice and dessert wine. However, the method was robust for the analysis of fermentation samples and table wines. Results were within ±10% agreement with data generated from typical HPLC-based analyses. The isatin method is therefore considered suitable for the routine analysis required to support research into the utilization or release of proline by yeast during fermentation.Danfeng Long, Kerry L.

Kate Richards: madness
No full textKate Richards’ bleakly beautiful, confronting and important book, Madness: A Memoir, describes her 15 years coping with psychosis and depression, and her long, hard-won journey back to sanity, with the help of a wise and compassionate psychologist.
In this video, she speaks with Ranjana Srivastava, an oncologist and fellow author, about her experience – and about being able to write from deep within it, with expertise as both a medical researcher and writer.

Replication Data for Statistical Analysis
No full textIncluded here is a dataset with gesture form coding from the study author (Kate Mesh). Statistical analysis of the dataset was performed using R version 3.6.1 (R Core Team, 2019), with the package, lmer (Bates, Maechler, Bolcher & Walker, 2015). An R script is attached for the purposes of replication.

Piire ületamas: Uus Naine Kate Chopini romaanis „Virgumine“
No full textBakalaureusetöö uurimiskeskmeks on 19. sajandi teise poole Ameerika Ühendriikide naisautori Kate Chopini romaan „Virgumine“ (1899), mida analüüsitakse ajastu sotsiaalkultuurilisest kontekstist lähtuvalt. Töös seostatakse Kate Chopini kaasaeg tema loominguga ning näidatakse, kuidas 19. sajandi aktuaalsed diskussioonid naise positsioonist ühiskonnas leiavad kajastust ka „Virgumises“. Konkreetselt keskendutakse Uue Naise (ingl New Woman) fenomenile ning vaadeldakse, kuidas Kate Chopin autorina seda ebakonventsionaalset naisetüüpi käsitleb. Töö eesmärk on analüüsida Uue Naise kui muutuvate soorollide võrdkuju Chopini romaanis „Virgumine“, asetades romaani Uue Naise fenomeni laiemasse kultuurilisse konteksti
