Bioassay-guided isolation and identification of antimicrobial compounds from thyme essential oil by means of overpressured layer chromatography, bioautography and GC-MS
No full textA simple method is described for efficient isolation of compounds having an antibacterial effect.
Two thyme (Thymus vulgaris) essential oils, obtained from the market, were chosen as
prospective materials likely to feature several bioactive components when examined by thin layer
chromatography coupled with direct bioautography as a screening method. The newly developed
infusion overpressured layer chromatographic separation method coupled with direct
bioautography assured that only the active components were isolated by means of overrun
overpressured layer chromatography with online detection and fractionation. Each of the 5
collected fractions represented one of the five antimicrobial essential oil components designated
at the screening. The purity and the activity of the fractions were confirmed with chromatography
coupled various detection methods (UV, vanillin-sulphuric acid reagent, direct bioautography).
The antibacterial components were identified with GC-MS as thymol, carvacrol, linalool, diethylphthalate,
and alpha-terpineol. The oil component diethyl-phthalate is an artificial compound,
used as plasticizer or detergent bases in the industry. Our results support that exploiting its
flexibility and the possible hyphenations, overpressured layer chromatography is especially
attractive for isolation of antimicrobial components from various matrixes
Stability of one-step and linear multistep methods - a matrix technique approach
Get PDFWe investigate the stability of one-step and linear multistep methods from a new direction. Our aim is to modify the long and technical proof which is consequently omitted in almost every textbook and make it user-friendly. In the literature the techniques of numerical solution of initial value problems and boundary value problems seem to have almost nothing in common which is quite surprising. Our new approach uses matrix techniques opposed to the usual recursion approach, thus applying the techniques of boundary value problems to initial value problems. Even though the proof remains long, it is easier to follow and connects two seemingly separated areas, consequently this approach might have educational profit
Emil Fahrenkamp: Bauten und Projekte für Berlin
No full textThema der vorliegenden Arbeit ist die umfassende Aufarbeitung und Dokumentation der Bauten und Projekte Emil Fahrenkamps (*1885, 1966) in Berlin und Potsdam-Babelsberg sowie die kritische Einordnung seiner Arbeiten in den Kontext der Baugeschichte des 20. Jahrhunderts. Den zentralen Untersuchungsgegenstand bildet, neben der gebaudespezifischen Erfassung der Bau- und Planungsprozesse und der Gebaudebeschreibung Fahrenkamps grosstadtische Arbeiten und Entwurfe in ihrem gesellschaftlichen Kontext zu analysieren. Zeitlich umfasst die Arbeitsphase Fahrenkamps in Berlin die Jahre zwischen 1920 und 1945, in denen er seine bauliche Aktivitaten sowohl fur private Bauherrn als auch fur offentliche Auftraggeber etablieren und ausbauen konnte. Emil Fahrenkamp galt bisher als ein Vertreter der Moderne in Deutschland. Dieses fest gefugte Bild entstand durch die einseitige Gleichsetzung seiner Architektur mit dem Shell-Haus, das in den Jahren 192932 nach seinen Planen in Berlin errichtet wurde und das zur Ikone grosstadtischen Bauens in der baugeschichtlichen Bewertung geworden ist. Die vorliegende Arbeit sucht diese Sicht auf Emil Fahrenkamp kritisch zu hinterfragen und zu differenzieren. Indem sie exemplarisch seine Arbeiten fur Berlin aufarbeitet, gelingt eine neue Sicht seiner architektonischen Intention und damit eine Neubewertung seiner Bedeutung in der deutschen Baugeschichte des 20. Jahrhunderts.Architectur

Choral Works of Emil Hradecký
No full textThis thesis deals with the figure of contemporary Czech composer Emil Hradecký with a special respect to choral compositions. In the first chapter the author introduces Emil Hradecký as a mUSlC teacher, composer and publisher. In the following chapter she describes Hradecký's music work in general, inc1uding his methodological handbooks and instructive pieces. The core of the thesis is the part which focuses on Hradecký's choral works. It contains a complete list of his choral works and analysis of several works which il1ustrate his various compositional styles. The significance of this thesis is in its survey of Hradecký's choral works, especially due to the fact that a monograph about this composer has not been published yet. The author hopes that this thesis might contribute to extending of the general knowledge about this composer
