Within the scope of this article is the development of a mathematical model of an insulating panel made from grain husks and the optimization of the panel regarding the thermal characteristics by using this self-developed thermodynamically model. The model comprises one husk as the smallest unit of the insulating panel. In order to solve the model analytically, the following relevant parameters have been determined:
The solved model is validated with produced insulating panels out of grain husks. The optimization of the effective thermal conductivity λeff is done regarding the following parameters:
According to the results of the simulation, by using Xenon as filling gas instead of air, the effective thermal conductivity λeff can be reduced by 21.6%. The optimal value of the husk’s edge length a depends on the filling gas und therefore varies between 4 and 6 mm. The optimization of the edge length leads to a reduction of the effective thermal conductivity λeff of 7.5 %, according to the model. When implementing individual calculated optimizations in real insulation boards, the thermal conductivity could be improved by up to 32 %. The project is funded by BMWi, the German ministry of economy and energy, and supervised by AiF, the working group of industrial research associations.

Alopecurus rendlei is an annual grass species of the Poaceae family. The species’
north-eastern distribution range includes Luxembourg and the southern part of Belgium.
The species has shown a dramatic decline in the past decade in both countries and in neighbouring
Germany. The aim of the present study was to investigate the characteristics of A.
rendlei populations in Luxembourg and its bordering regions in Belgium, Germany, and
France and to determine whether regions and populations differ in plant morphology and
site ecology. At each survey site plant material from A. rendlei was collected and the species’
population density was calculated. Furthermore, soil samples were taken, and the floristic
composition of the sites overall was analysed. Within the study area, mean density of A.
rendlei plants per population showed extensive variation. The presence of the species could
only be confirmed in half of the known sites, out of which more than 50% were meadows.
In reference to plant morphology, Luxemburgish populations were similar to the Belgian
ones, except for one population in the south of Luxembourg that displayed many similarities
to French populations. In the German population the internodia were shorter than in
the other studied populations. Plant size as well as leaf length and the leaf length-width ratio
increased from Belgium to Luxembourg and France. The conclusions include management
and further research proposals. Based on our results as well as those of further investigations
that are required, the decline of Alopecurus rendlei should be counteracted.
