Biosensor-based Methods for Detection of Microcystins as Early Warning Systems

Popular Abstract in English Global invasion of our precious watercourses by cyanobacteria poses great threat to human- and animal health by deteriorating water systems. In fact, this problem is not likely to be solved in the near future as cyanobacteria are associated with pollution of waterways. Consequently, water sources are subject to contamination by natural toxins produced by abundant growthCyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. The high toxicity and in

Unsplittable max-min demand allocation - a routing problem

The end-to-end assignment of bandwidth to node-pairs (demands) in a communication network can be considered fair if it is distributed according to the max-min fair (MMF) principle. This paper investigates the problem of obtaining an MMF allocation if each demand is required to use exactly one path (i.e., to use unsplittable flows). First it is shown that the problem is NP-hard, both if each demand
