This phenomenon is the masking of endotoxin in undiluted materials, and is thought to be attributable to combinations of specific excipients. This differs from the inhibition or interference of endo toxin tests caused by pH, high divalent ion concentrations, chelators, serine proteases and beta­glucans, which can usually be overcome using a pre­treatment such as dilution. This guide provides an...

The PEP-N project at SLAC [1] consists of a Very Low Energy small electron Ring (VLER) that will collide with the low-energy 3.1 GeV positron beam (LER) of PEP-II, producing center-of-mass energies between 1.1 GeV and the J/ψ. The beams will collide head-on and will be separated in the detector magnetic field which is part of the Interaction Region (IR) [2]. The IP β functions were chosen such ...

2014 Recently we have developed a Couette viscosimeter for studying the shearing of colloidal crystals. We report here that with increasing shear rate the colloidal crystal melts (for 03C9crit) and above a critical shear rate, 03C9T0, Taylor instabilities develop. After stopping the shearing flow the suspension recrystallizes in a special texture which preserves the pattern of the Taylor rolls....

Preliminary estimates[?] indicate that single bunch in the LER of the PEP-II B-factory has to be stable, both longitudinally and transversely, at the maximum design bunch current 1.8 mA (beam current 3A). However, realistic wakes of the machine has been constructed only recently using results of the extensive numerical simulations of the vacuum components of the ring[?]. Additional to that, the...

Abstract Land equivalent ratio (LER) is a most widely used indicator of yield advantage multi-crop farms over sole-crop farms, and usually measured using crop biomass per unit area. Most often, yields are compared between both systems the same In this paper, we demonstrate that although area plant different, LER remains invariant. As corollary, time land use efficiency, derived from LER, also r...

Register allocation and instruction scheduling are antagonistic optimizations: Whichever is applied rst, it will impede the other. To solve this problem, we propose dependence-conscious colouring, a register allocation method that takes the dependence graph used by the instruction schedu-ler into consideration. Dependence-conscious colouring consists of two parts: First, the interference graph ...
