Climate change constitutes a selective pressure on populations because increasing temperatures result in a selective advantage or disadvantage for certain individuals depending on their genetic predisposition.We wrote a program to simulate such developments using the example of the reproductive success of cold-blooded animals. Cold-blooded animals were the obvious choice because their dependence on temperature can easily be described using mathematical …
Thermally triggered motion of pyrolytic graphite on a magnet array
When hydrocarbon is heated to its decomposition temperature pyrolytic graphite can be crystalized in ordered layers. This material has an unusual characteristic. It can levitate above a chequerboard arrangement of magnets due to its diamagnetic property. We delved into the reason for this phenomenon. One question in particular interested us: can the levitation process be manipulated by applying heat or …
Rekari – the intuitive platform for diverse drone operations
The areas of application for drones seem almost unlimited. However, when it comes to using such systems in specific use cases, there are often problems in terms of practical application. Use of the systems may be some-what less appealing if there are difficulties with operation or a lack of uncomplicated solutions, for example. It is often the case that potential …
