Plant representations using whole plant envelopes with homogeneous leaf area density (LAD) were not reliable to estimate light partitioning, irrespective of the accuracy of envelope definition.
Therefore we developed a light partitioning model, that calculates the available amount of photosynthetically active radiation (PAR) at the top of the canopy for a given point within a strip of a smaller, subordinate crop.
In this paper, we studied the light interception of herbaceous plants with contrasting architectures (monocultures and binary mixtures) grown at high or low density and sought to determine the important architectural features necessary to account for light partitioning among individual plants.
We designed the SIMBA-IC model to simulate nitrogen and light partitioning and crop management, which can differ across the different zones of the field (banana row, small and large inter-rows), and to assess agronomic and environmental performances of banana cover cropping systems under scenarios of different spatial arrangement.
The massive internal spaces seen in many surviving donjons can be misleading; they would have been divided into several rooms by light partitions, as in a modern office building.
Variability in leaf inclination is known to enhance the photosynthetic light capture of individual tree crowns (e.g. [49]), while in a study of mixed red clover (Trifolium pratense) and tall fescue (Festuca arundinacea) canopy differences in leaf inclination between the two species increase equality in light partitioning between the taller fescue and shorter clover [50].
When canopy closure started, the turbid medium approach was unable to properly infer light partitioning because of the vertical structure of the canopy.
doi 10.1093/aob/mct251 The growth of crops in mixtures is more difficult to predict than in pure stands, with light partitioning and leaf area expansion accounting for a lot of the variability observed.
This new type of locally resonant unit can easily be installed into building envelope materials, such as extruded hollow concrete, hollow wooden board and other types of light weight partition panels, to enhance their sound proof property.
So far, some of its assessed material properties (e.g. density, fire resistance, durability, thermal conductivity, compression and bending strengths, and impact resistance) suggest adequacy of this product for several building applications, such as a thermal insulation product, a light weight partition wall, a ceiling coating, or as indoor doors, among other possibilities.
