The old‑fashioned mixture of chain stores and independent retailers has been disappearing; our average high street has few or no independent shops.
From the dependence of the rate of thermal degradation of PMMA on molecular weight at low degradation temperatures, it was concluded that thermal degradation was initiated by a mixture of chain end and random chain scission initiation, followed by depropagation and first-order termination.
Although Joshua Horvath's excellent sound design brings Lear out onto the heath in the midst of a raging thunderstorm, I was most taken by Daniel Ostling's unit set (a brilliant mixture of chain-link fencing and smoked glass panels that comes apart very much in the style of a Japanese box puzzle).
Fluorotelomer-based materials are composed of a mixture of chain lengths (Kissa 2002), so biotransformation of these compounds could explain concurrent human exposure to PFCAs of several chain lengths.
The resulting products are polydisperse mixtures of chains, that while retaining most of heparin's natural structure also contain unnatural, unsaturated uronate residues at the nonreducing ends of some of their chains and unnatural 1,6-anhydro ring structures at the reducing ends of some of their chains.
Crystallization thus commences from a heterogeneous mixture of native chains and chains with a longer persistence length (higher effective rigidity) and consequentially a lower effective height of the entropic barrier for crystallization.
Only a few algal bioassay studies (Table 22) summarized in OECD (2007) reported NOEC or EC10 values, and most of these were for mixtures of chain lengths.
However, in the environment, the alcohols will not appear as individual chain lengths but rather as mixtures of chain lengths as evidenced by monitoring studies of WWTP effluents in North America (Dyer et al., 2006a, 2006b; Eadsforth et al., 2006; Morrall et al., 2006).
Extensive acute and chronic toxicity data to fish, both freshwater and marine species, invertebrates, and algae for AS ranging from chainlengths of C8 C18 both as single chainlengths and in mixtures of chain lengths, are presented in HERA (2002) and OECD (2007).
Traditionally used lipid emulsions are based solely upon soybean oil, which is rich in the n-6 fatty acid linoleic acid, or a 50 50 mix of vegetable oil rich in medium-chain saturated fatty acids and soybean oil (often termed MCT/LCT to indicate the mixture of medium chain and long chain triglycerides).
