Endosymbiotic Green Algae in Paramecium bursaria: A New Isolation Method and a Simple Diagnostic PCR Approach for the Identification

Diversity, 2020
Paramecium bursaria is a single-celled model organism for studying endosymbiosis among ciliates and green algae. Most strains of P. bursaria bear either Chlorella variabilis or Micractinium conductrix as endosymbionts.

Spectra–Structure Correlations in Isotopomers of Ethanol (CX₃CX₂OX; X = H, D): Combined Near-Infrared and Anharmonic Computational Study

Molecules, 2019
The effect of isotopic substitution on near-infrared (NIR) spectra has not been studied in detail. With an exception of few major bands, it is difficult to follow the spectral changes due to complexity of NIR spectra.

Progress and Criticism of Progress as a Characteristic of Modern Civilizations in the Work of Friedrich Nietzsche and Ludwig Wittgenstein

Labyrinth: An International Journal for Philosophy, Value Theory and Sociocultural Hermeneutics
Superficially, the proximity of Wittgenstein's work and its undisputed influence by Friedrich Nietzsche's ideas and concepts suggests that there are also overlaps in the large and in Nietzsche's work decisive field of progress and criticism of progress.
