Ultrasonic spectroscopy of liquid filled piezoelectric tube
The characterization and classification of liquids through instrumentation is essential in many industries. As such, measuring the characteristics of liquids is not just useful as a control parameter within an industrial process; such measurements can also be used to classify the liquid. Such a …

High-resolution ultrasonic non-destructive testing
The use of ultra-short pulse wideband ultrasonic transducers in Non-Destructive-Testing (NDT) has been investigated both theoretically and experimentally. It is demonstrated that the resolution of pulse-echo NDT is affected by diffraction effects which also complicate the interpretation of echo …

Schallspektroskopische Charakterisierung von submikronen Emulsionen
Zu den wenigen Methoden, die sich für eine prozessnahe Charakterisierung von dispersen Stoffsystemen bezüglich der Partikelgrößenverteilung eignen, zählt die Schalldämpfungsspektroskopie. Dennoch ist ihr Einsatz in der industriellen Praxis auf einen überschaubaren Bereich an Messaufgaben und …

Interakce hyaluronanu s DNA
Diplomová práce se zabývá studiem možných interakcí mezi hyaluronanem (HA) a plasmidovou DNA (pDNA). Plasmidová DNA byla izolována z E. coli JM 109 (pUC19) a resuspendována v TE pufru stejně jako vysokomolekulární hyaluronan. Jednotlivé vzorky pDNA, HA a pDNA-HA byly charakterizovány pomocí gelové …
