An abrasive wear resistant substance is placed between the femoral component and the acetabular cup named the acetabular interface (Jahan and Edwards 2013b).
Even though some growth factor peptides such as EGF, TGF- β, and insulin-like growth factor 1 (IGF1) were relatively temperature and time resistant, substance P (SubP) and calcitonin gene-related peptide (CGRP) significantly degraded at −15°C in 6 weeks, +4°C in 24 hours, and +25°C in 6 hours [ 23].
Cold-resistant substances of insects include two types, small molecules and antifreezing proteins (Chen et al. 2010).
The copperplate is first coated with an acid-resistant substance, called the etching ground, through which the design is drawn with a sharp tool.
Medicinal mushroom may be used as a source of oxidation-resistant substance and may scavenge free radicals.
If you're going down the water-resistant route, you may prefer to use scraps of linoleum or some other water-resistant substance.
In conjunction with the BOD, the COD test is helpful in indicating toxic conditions and the presence of biologically resistant organic substances (Sawyer and McCarty 1978).
The BOD value indicating the amount of biologically oxidizable organic matter and COD value indicating toxic conditions due to the presence of biologically resistant organic substances, are decreasing during 15 days remediation study of DWW using D. tharense.
When mouse cells that had been genetically modified to lack Bak and Bax were grown in cell culture, they were found to be resistant to substances that normally induce necrosis.
Reversing this accumulation may thus be valuable, but has proven challenging, doubtless because substances resistant to cellular catabolism are inherently hard to degrade.
Similar trends were observed in the case of strains resistant to antibacterial substances.
