The polysulfone resins, introduced in the 1960s, are tough, strong, stiff, and resistant to decomposition by heat or chemical attack.
The food, given the museological resources of the day, was prone to decomposition, and the collection was steered towards local trades less inclined to rot, including leather and silk-weaving.
Some 145 million tons of waste, from the Truman-era primordial muck at the marshy bottom to more recognizable castoffs of the early Bush years, will traverse the sludgy slope to decomposition, an unseen simmer of microbial breakdown.
Nonvulcanized, low-molecular-weight polysiloxane fluids are exceptionally stable to decomposition by heat, water, or oxidizing agents and are good electrical insulators.
Saprotrophic organisms are considered critical to decomposition and nutrient cycling and include fungi, certain bacteria, and funguslike organisms known as water molds (phylum Oomycota).
This property is advantageous but introduces some difficulties with respect to decomposition into subpopulations.
It demonstrates that the third step in Fig. 6b is due to decomposition of heteropoly acid.
Its content reduces due to decomposition as temperature of annealing is increased.
In other words, the degradation rate was the time to decomposition within a defined period.
The total K released from coffee residues was not significantly related to decomposition (data not shown).
It was also thermally stable up to decomposition temperature of PGA.
