Analysis of biology midterm exam items using a comparison of the classical theory test and the Rasch model

JPBI (Jurnal Pendidikan Biologi Indonesia)
In biology learning, test instruments are essential for assessing students' understanding of complex concepts. A test instrument is a crucial factor in learning evaluation; however, its implementation remains minimal.

Die Manifestation des elektrochemischen Potentialgradienten in der Elektrochemie

Angewandte Chemie, EarlyView.
Die Überspannung stellt eine elektrochemische Potentialdifferenz an der Festkörper‐Flüssigkeits‐Grenzfläche dar, die sich auf unterschiedliche Weise manifestieren kann. Im Allgemeinen kann sie nicht nur die Reaktion entlang der Reaktionskoordinate antreiben, sondern auch die chemischen Potentiale in der erweiterten Umgebung modulieren, welche die ...

Erweiterung der Peptidligation auf Saure pH‐Bereiche und Schnittstellen mit Glykosylierten und Phosphorylierten Aminosäuren

Angewandte Chemie, EarlyView.
Ein pyridinhaltiges Ligationsauxiliar beseitigt einen wesentlichen Engpass der Peptidligationschemie. Der für die Ligation nutzbare pH‐Bereich von 2,0–7,5 hilft, Epimerisierung zu vermeiden. Die native chemische Ligation (NCL) verläuft an praktisch jeder Ligationsstelle, einschließlich Reaktionen an β‐verzweigten sowie O‑glykosylierten oder O ...
