1 Getting Hot

چکیده
We review the current status of the ’Parker hypothesis’ which suggests that the solar corona is heated by a multitude of small flare-like events called nanoflares. Space-born coronal imagers such as SXT, EIT or TRACE have allowed to test Parker’s hypothesis observationally. Combining the results from different authors it seems that we are close to falsifying the hypothesis, i.e. there are not enough nanoflares to heat the corona. The only remaining hope for nanoflare-adepts is the transition region which contains various types of impulsive events such as explosive events or blinkers whose role and mutual relation is not sufficiently understood yet to make a final verdict on Parker’s hypothesis.

Design for Environment – Do We Get the Focus Right?
Sometimes , products resulting from design for environment (DFE) endeavours are sub-optimisations from an environmental perspective, because the tool determines the process and not vice versa. For a more systematic way of getting the focus right, a hierarchy of focusing is introduced: 1. What is the function provided and what is the optimal way of providing it while making a business out of it?...
