The electrochemical oxidation of oxalate at a platinum electrode in acetonitrile solutions as studied by cyclic and rotating-ring disk voltammetry and controlled potential coulometry shows an irreversible two-electron oxidation at ca. 0.3 V vs. SCE to CO2 with no intermediates detectable by these techniques. The oxidation of oxalate in the presence of several fluorescers (such as rubrene, 9, IO...

The objective of this study was to determine the effects of a CO, treatment on the pH and soluble concentrations of inorganic contaminants in alkaline fly ash and spent shale solid wastes. A two-level (low and high), three-variable (moisture, time and pressure) statistical experiment was used to determine optimum CO, treatment conditions. Treated and untreated samples were subjected to solubili...

D liier beschriebene Ultrarotabsorptionsschreiber (abgekürzt URAS) der Badischen Anilin& Sodafabrik Ludwigshafen a. Rh. ermöglicht eine vollautomatische Gasanalyse, die ohne Zuhilfenahme von chemischen Absorptionsmitteln eine fortlaufende und spezifische Konzentrationsmessung bei Gasen auf rein physikalischer Grundlage durchzuführen gestattet. Sein universelles Meßprinzip ermöglicht eine Konzen...

PHYSIOLOGICAL AND CHEMICAL CONSIDERATIONS Definitions: Van Slyke72 has defined acidosis as a condition in which the bicarbonate of the blood or serum, or, more exactly, the base available for combination with bicarbonate, is diminished. Alkalosis is a condition in which there is in the blood or serum an abnormal excess of bicarbonate, or base available for combination with bicarbonate. These de...

Abstract The European Flightpath 2050 connectivity goal, to enable people reach any desired destination, door door, in 4 hours, increases the interest Small Air Transportation (SAT), enhance global connectivity. goal should come alongside with environmental target: FlightPath aims reduce by 75% C02 emissions and 90% NOx emissions. Within EU Clean Sky 2 framework, a future affordable green commu...

In this contribution, we propose an interactive multicriteria optimisation framework for the time and space assembly line balancing problem. The framework allows decision maker interaction by means of reference points to obtain the most interesting non-dominated solutions. The principal components of the framework are the g-dominance preference scheme and a state-of-the-art memetic multiobjecti...

We pose a monotonicity conjecture on the number of pseudo-triangulations of any planar point set, and check it on two prominent families of point sets, namely the so-called double circle and double chain. The latter has asymptotically 12nnΘ(1) pointed pseudo-triangulations, which lies significantly above the maximum number of triangulations in a planar point set known so far. ⋆ Parts of this wo...

Soil was treated with "C-ring-labeled fluometuron [N,N-dimethyl-N'[3-(trifluoromethyl)phenyll urea] (0.516 and 5.16 pmol gl), air-dried, and stored for 6 months at 5 "C. The 14C was then extracted from soil with methanol by conventional extraction (twice with MeOH/H20 8020 v/v; 2:l extract/soil v/w) and with CO2 using a supercritical fluid extractor. Supercritical fluid extraction (SFE) method ...

Guinea pigs were exposed to 15% C02 in 21% 02 for periods up to seven days. Two separate oxygen dissociation curves were determined at a PC02 of 40 mm Hg and a Pco2 of 115 mm Hg on pooled blood samples. Red cell pH and cation concentrations were also measured. Pr(0 fell from 27.8 mm Hg to 18.6 at one day exposure and rose again to 24.7 after seven days of exposure to 15% C02. Blood oxygen capac...

The application of advanced millimeter/far infrared sources to substantially improve the effectiveness of collective Thomson scattering plasma diagnostics is discussed. Gyrotrons, C02 lasers and far infrared lasers which are optically pumped with CO 2 laser radiation can now provide important new capabilities in terms of combined high peak power and high average power, fine frequency tunability...
