Abstract

The EXO-200 experiment searched for neutrinoless double-beta decay of $^{136}$Xe with a single-phase liquid xenon detector. It used an active mass of 110 kg of 80.6%-enriched liquid xenon in an ultra-low background time projection chamber with ionization and scintillation detection and readout. This paper describes the design and performance of the various support systems necessary for detector operation, including cryogenics, xenon handling, and controls. Novel features of the system were driven by the need to protect the thin-walled detector chamber containing the liquid xenon, to achieve high chemical purity of the Xe, and to maintain thermal uniformity across the detector., Manuscript updated in response to JINST reviewer comments

Abstract

Turmeric oleoresin was fed for 102-109 days to groups of eight pigs (males and females) at dietary levels providing intakes of 60, 296 and 1551 mg/kg body weight/day. Twelve pigs served as controls. The highest dose group showed a reduction in weight gain and in food-conversion efficiency. Statistically significant dose-related increases in the weight of the liver and the thyroid were recorded at all dose levels. Pericholangitis, hyperplasia of the thyroid and epithelial changes in the kidney and urinary bladder were observed in the two higher dose groups. It is questionable whether a no-adverse-effect level can be established on the basis of the observations in this experiment. Further studies should be initiated to elucidate the mechanism of action of turmeric.

Abstract

Ponceau 6R (the tetrasodium salt of 1-(4-sulpho-1-naphthyl-azo)-2-naphthol-3,6,8-trisulphonic acid) was fed to pigs at dietary levels of 0 (control), 100, 500 and 1500 mg/kg body wt./day for 102--105 days. In the 1500-mg group a decrease in weight gain and food utilization was seen, and 1 pig died with a hemolytic anaemia. Dose dependent discolouration was seen of the connective tissue in the groups given 1500 and 500 mg/kg body wt. For this effect the no-effect-level was 100 mg Ponceau 6R/kg body wt. per day.
