Adding β-glycosidase into grape wine for enhancing aroma was investigated using gas chromatography-mass spectrometry (GC-MS) and Kramer sensory evaluation. Compared with the extract from control wines, the extract from enzyme-treated wines increased more aromatic compounds using steam distillation extraction (SDE) and GC-MS analyses. Theses aromatic compounds were as follows: 3-methyl-1-butanol...

In their anthology, Olaf Kramer and Markus Gottschling demonstrate that a closer look at rhetoric as both the technique analytical tool concerned with persuasion can open up new perspectives on science communication for scientists well practitioners.

Abstract For many decades, Kramer’s sampling theorem has been attracting enormous interest in view of its important applications various branches. In this paper we present a new approach to Kramer-type theory based on spectral differential equations higher order an interval the real line. Its novelty relies partly fact that corresponding eigenfunctions are orthogonal with respect scalar product...
