Voice range profile (VRP) measurement was used to evaluate the vocal capabilities of 180 children aged between 4 and 12 years without voice pathology. There were 10 boys and 10 girls in each age group. Using an automatic VRP measurement system, F0 and SPL dB (lin) were determined and displayed two-dimensionally in real time. The speaking voice, the shouting(More)
Ether lipids with alkyl chains of uniform length and varying amine headgroups were synthesized and assembled into bilayer structures in aqueous solution, which served as templates for the formation of silica in two and three dimensions produced under ambient conditions. Dynamic light scattering revealed that unilamellar vesicles of the aminolipids are(More)
Post-translational modifications of proteins are important modulators of protein function. In order to identify the specific consequences of individual modifications, general methods are required for homogeneous production of modified proteins. The direct installation of modified amino acids by genetic code expansion facilitates the production of such(More)
