Managing Security Risks During Requirements Engineering

Roman Wirtz
Due to the ongoing digitalization of our everyday life, the consideration of security for software-intensive systems is of great importance. The number of reported security incidents highly increased in the last years. Each may lead to substantial damage for companies, not only financially, but also in terms of reputation loss. In order to avoid such incidents, security should be addressed as early as possible during software development, i.e. during requirements engineering by following the principle...

Der Hypoxie-induzierbare Faktor HIF-2alpha ist essentiell für die Gehirnentwicklung: eine in vivo- und in vitro-Studie unter Sauerstoffmangel

Kira Kleszka
Die physiologische Funktion und das Überleben von Zellen erfordert eine ausreichende Gewebeoxygenierung. Insbesondere im Gehirn muss das Sauerstoffangebot streng reguliert werden, um Hypoxie und somit einen irreversiblen Zellschaden zu vermeiden. Bereits während der Entwicklung zeigen sich neurale Stammzellen sensibel auf fluktuierende Sauerstoffkonzentrationen. Der Transkriptionsfaktorkomplex Hypoxie-induzierbarer Faktor (HIF) übernimmt eine Schlüsselrolle in der Adaptation von Zellen an hypoxische Zustände. Während die profunde Rolle von HIF-1a während der Gehirnentwicklung eindrucksvoll durch Tomita et al. gezeigt werden konnte,...

Investigation of zinc oxide photocatalytic reactor membrane system for waste water treatment

Chin Boon Ong
Photocatalysis is a highly promising technology which utilized photon energy for the mineralization of organic pollutants through chemical oxidation reaction processes. Post-treatment is needed to recover the photocatalyst from the solution after the reaction. Membrane filtration is integrated to the photocatalysis process due to their ability to reject the suspended photocatalyst and further improving the permeate quality by rejecting un-treated or remained organic matter in the feed. However, the major drawback of the integration is...
