  The pros and cons of replacing traditional materials with polymeric materials in solar thermosiphon systems were analysed by adopting a total cost accounting approach. In terms of climatic and environmental performance, polymeric materials reveal better key figures than traditional ones like metals. In terms of present value total cost of energy, taking into account functional capability, end user investment cost, O&M cost, reliability and climatic cost, the results suggest that this may also be true when comparing a polymeric based thermosiphon system with a high efficient thermosiphon system of conventional materials for DHW production in the southern Europe regions. When present values for total energy cost are assessed for the total DHW systems including both the solar heating system and the auxiliary electric heating system, the difference in energy cost between the polymeric and the traditional systems is markedly reduced. The main reason for the difference in results can be related to the difference in thermal performance between the two systems. It can be concluded that the choice of auxiliary heating source is of utmost importance for the economical competiveness of systems and that electric heating may not be the best choice.

Experimental nuclear level densities and interpretation within the microcanonical ensemble. Proceedings of Science (PoS). ISSN 1824-8039. Vis sammendrag

  Statistical properties of atomic nuclei are studied as function of the number of neutrons. The experimental method is based on particle-g coincidences measured in light-ion reactions with one charged ejectile. From particle-g coincidences, level densities and radiative strength functions can be simultaneously extracted from one and the same data set. Mid-shell nuclei show significant odd-even entropy differences interpreted as the single-particle entropy of the valence nucleon. However, these properties change when approaching closed shells. A model within the framework of the microcanonical ensemble is presented and compared with data from the molybdenum isotopes. The odd-even entropy difference disappears in the vicinity of the N =50 shell, and an overshoot of positive parity states is predicted.

  Sonnenkollektoren können Solarenergie in thermische Energie für Heizungen und Warmwasseraufbereitung umwandeln. Der Solarabsorber muss dabei hohen thermischen und mechanischen Belastungen standhalten. Wurden für diese Anwendung bisher hauptsächlich Metalle eingesetzt, hat ein Forschungskonsortium nun spezielle Polymerblends dafür entwickelt. Im Vordergrund stand die effektive Extrusion eines Hochleistungskunststoffs zu großflächigen Doppelstegplatten.

  Norway has for a long time lagged behind on the statistics of utilization of solar heat. But in August 2008 the Norwegian institution Enova opened a programme for subsidizing solar heating systems. This made way to an increased interest on solar heat systems in Norway, as has earlier been seen in many other countries Rekstad will in this lecture discuss how solar heat utilization in buildings compares to alternative heating systems. Different technical solutions are available, and some research on solar heat is being done on the University of Oslo.

  The paper outlines the impact of temperature on polymeric solar thermal collectors, and methods to reduce the thermal degradation. If solar thermal shall play the role in the future that is desired and forecasted, new materials will be required. Both the IEA's-Solar heating and Cooling Programme and EU’s 7 Framework Programme focus on polymeric collectors. The main barrier for a full breakthrough for the polymer solution is the temperature sustainability in situations where stagnation temperatures occur. This problem is significantly smaller for Nordic climate than at for latitudes further south. The strong engagement revealed by leading industries in the polymer sector can be an inspiration and opportunity for scientific and technical Nordic research groups to take a frontier position in this field.
