To apply a systematic approach to select desired and avoid problematic material combinations in product design and intermediate recycling products, a decision tree was developed, based on the separation and recycling technologies available nowadays and on metallurgical and thermodynamic properties of the materials.
However, the problematic material swelling/recovery effect due to the elastic recovery of materials in UPM remains unresolved.
Why venture into problematic material at all?
In fact, despite the electrifying (and, likely, to-be-award-nominated) performance of DiCaprio and other actors involved, particularly Jonah Hill and Rob Reiner, as well as the unassailable expertise and skill of Scorcese, the film is, beyond its problematic material, problematic for reasons beyond its author.
Designed by Robin Herd, the innovative but problematic Mallite material was used in its construction.
Radiocarbon dating has provided an absolute chronology; however, the results are problematic due to the partly reworked character of the organic material in the loamy sediments.
However, deciphering growth factor receptor kinase pathways at the time of acquisition of tamoxifen resistance has proved notoriously problematic in clinical material because of the difficulty in obtaining paired samples before tamoxifen administration and subsequently on relapse.
Because the spatial distribution of LNAPL at a field site is strongly dependent on both the spill circumstances and the heterogeneity of the geologic materials, which can be problematic for in-situ determination, alternative methods for estimating source-zone emissions are needed.
Therefore, the presence of a porous material in the sensor allows to investigate complex mixtures of vapor effectively that is problematic for a flat surface structure.
7 was joined to these discussions, is somewhat problematic: Aristotle's disciple, Eudemus, when putting together his own Physics, apparently did not discuss the material in bk. 7, although he followed the discussion of both Aristotelian inquiries, as Simplicius attests.
