Aspects of the kinetics and thermodynamics of the iron-catalysed Haber-Weiss reaction are discussed with special emphasis on the potential in vivo sources of iron. In addition, the properties of the iron chelates that inhibit the Haber-Weiss reaction are considered.

Software Reengineering has been a topic at Bosch for 10 years now. This paper reports about our experiences during this time, about ongoing reengineering activities, and about potential topics for the research community.

The electronic properties of a square lattice under an applied perpendicular magnetic field in the presence of impurities or vacancies are investigated by the tight-binding method including up to second nearest neighbor interactions. These imperfections result in new gaps and bands in the Hofstadter butterfly even when the second order interactions break the bipartite symmetry. In addition, the...

Yaşanan Covid-19 salgını ile birlikte medyanın bilgilendirme ve yönlendirme işlevlerinin daha da önemli hale geldiği görülmektedir. Sağlık alanı, özellikle de virüs aşı gibi konular üzerine tahminler yürüterek değerlendirme yapılamayan uzmanlık gerektiren bir alan olduğu için toplum üzerinde medya aracılığıyla ulaşılabilecek sağlık alanındaki uzmanların etkisi olmaktadır. Bu çalışmada farklı ya...

This paper presents a developed process for fabrication of hollow silicon microneedle arrays. The inner hollow hole and the fluidic reservoir are fabricated in deep reactive ion etching. The profile of outside needles is achieved by the developed fabrication process, which combined isotropic etching and anisotropic etching with inductively coupled plasma (ICP) etcher. Using the combination of S...

At any phase in the development process, the process can shift back to an earlier phase. If, for instance, during testing a design flaw is discovered, the design phase and consequently also the phases after that need to be repeated. These types of setbacks in the software development process can be costly, especially if radical changes in the earlier phases (triggering even more radical changes...
