Application time

Research on wastewater treatment using constructed wetlands has shown that increasing the water retention time improves water treatment efficiency. Constructed wetlands are used for many purposes: polishing conventionally treated wastewater, holding and treating storm water, treating industrial or agricultural wastewater, and treating acid mine drainage and landfill leachates.

Software testing is traditionally seen as a difficult and time consuming activity that is hard to embed in the software development process. This book provides a different view. It explains to stakeholders how testing can add value to software development and doing business, and provides the tester with practical information. TestGoal is not just another methodology. Several good testing methodologies exist. But, like any other profession, also testing encompasses more than the simple application of a methodology.

In ebook "Biohybrid systems: Nerves, interfaces, and machines" the discipline of neurodesign is a highly interdisciplinary one, while at the same time in the process of maturing towards real-life applications. The breakthrough about to be achieved is to close the loop in communication between neural systems and electronic and mechatronic systems and actually let the nervous system adapt to the feedback from the man-made systems. To master this loop, scientists need a sound understanding of neurology, from the cellular to the systems scale, of man-made systems and how to connect the two.

In this study, the TiO2 passive layer was formed on a pure titanium substrate by simple oxidation in an aqueous solution of H2O2 35 wt.%. In order to determine the appropriate time for the oxidation of the pure titanium substrate, the corrosion rate of the metal in the solution of H2O2 was investigated. The electrochemical behaviour of the TiO2 passive layer on the Ti substrate was investigated in Hank’s solution at 37.5°C.
