The compounds Ln3Cu4P4O2ÿx (Ln = Pr, Sm) were prepared by annealing the elemental components in a NaCl/KCl flux. They crystallize with an ordered Zr3Cu4Si6-type structure (space group I4/mmm, Z = 2), which was refined from single-crystal X-ray data for both compounds; Pr3Cu4P4O2ÿx: a = 397.8(1), c = 2658.7(3) pm, R = 0.046 for 235 structure factors and 19 variable parameters; Sm3Cu4P4O2ÿx: a = ...

Aldose reductase (AR) has been implicated in the etiology of diabetic complications. Under diabetic conditions, the elevated vascular glucose level causes an increased flux through the polyol pathway, which induces functional and morphological changes associated with secondary diabetic complications such as cataract, neuropathy, and nephropathy. Oxidative stress, antioxidants, and the polyol pa...

Holothurians dominate the abyssal megabenthos. They are key consumers and bioturbators of surficial sediment. Compounds essential for holothurian reproduction, such as carotenoids, are in short supply in the deep ocean. Holothurians cannot synthesise carotenoids de novo; the compounds are supplied with the flux of phytodetritus. Therefore, the supply of these compounds may play an important rol...

Resin, the part of printed circuit board (PCB) waste, consists harmful elements and volatile organic compounds (VOCs) can cause pollution, but it also be potentially treated through vitrification. Hence, purpose this study is to investigate distribution VOCs analyze effects different flux agent types, pyrolysis duration, ratio, effect carrier gases vitrify resin waste in an atmospheric-pressure...

Abstract. We present first eddy covariance flux measurements with the PTR3-TOF-MS, a novel proton transfer time of flight reaction mass spectrometer. During 3 weeks in spring 2016, instrument recorded 10 Hz data biogenic volatile organic compounds above boreal forest, on top measurement tower at SMEAR (Station for Measuring Ecosystem –Atmosphere Relations) II station Hyytiälä, Finland. Flux and...

BACKGROUND Uraemic solutes accumulate in haemodialysis (HD) patients and interfere with physiological functions. Low-flux (LF) HD does not efficiently remove all uraemic compounds. We investigated whether large pore super-flux (SF) cellulose triacetate membranes (CTA) result in a better removal of uraemic solutes. METHODS Eleven patients were dialysed consecutively with LF-CTA and SF-CTA duri...

Eddy covariance (EC) is the preferable technique for flux measurements since it is the only direct flux determination method. It requires a continuum of high time resolution measurements (e.g. 5-20 Hz). For volatile organic compounds (VOC) soft ionization via proton transfer reaction has proven to be a quantitative method for real time mass spectrometry; here we use a proton transfer reaction t...
