Among various groups of dyes, reactive dyes are the most problematic, as their complex aromatic structures are resistant to bio-degradation [ 6].
The main structure in the middle was the most problematic and the entire thing peeled off of the plate even after a liberal application of ABS slurry.
The endophytic lifestyle has played an important role in the evolution of the morphology of reproductive structures (body) in one of the most problematic groups in fungal classification, the Leotiomycetes (Ascomycota).
Structurally the work's most problematic section is the prologue.
Such complementary tools may limit and remove the most problematic candidates in early phases or allow medicinal chemistry departments to optimize the structure early on.
While a solution with a market/project based structure has been favored by many, we conclude that this is the most problematic alternative.
Most problematic single nucleotide polymorphisms (SNP) that alter the amino acid sequence (non-synonymous SNPs) appear to impact the stability of protein structure (Yue et al., 2005; Yue et al., 2006).
Most problematic were prescription drugs.
Most problematic of all is iTunes.
The most problematic, however, was the Rail System.
