BACKGROUND Glucose degradation products (GDPs) are cytotoxic in vitro and potentially toxic in vivo during peritoneal dialysis (PD). We are presenting the results of a two-year randomized clinical trial of a new PD fluid, produced in a two-compartment bag and designed to minimize heat-induced glucose degradation while producing a near neutral pH. The(More)
We demonstrate scanning over 1.1 nm with a frequency shifting ring source using a Ytterbium doped fiber amplifier (YDFA). It is, to the best of our knowledge, the first time an YDFA has been used in this configuration, and operation in the 1-1.1 microm wavelength range is made possible. We demonstrate a novel timing scheme that suppresses unwanted(More)
A materials structural and chemical composition influences its optical scattering properties. In this paper we investigate the use of subsurface laser scattering (SLS) for inferring structural and chemical information of food products. We have constructed a computer vision system based on a supercontinuum laser light source and an AcoustoOptic Tunable(More)
The quality of a dairy product is largely determined by its microstructure which also affects its optical properties. Consequently, an assessment of the optical properties during production may be part of a feedback system for ensuring the quality of the production process. This paper presents a novel camera-based measurement technique that enables robust(More)
