TL;DR: In this paper, the authors removed the scales of the TITANIUM scales from the workpiece by placing it in an ELEVATED TEMPERATURE BATH at temperatures between 200*F and 300*F.
Abstract: TITANIUM SCALE, GENERALLY COMPRISING OXIDES AND NITRIDES OF TITANIUM, MAY BE REMOVED FROM TITANIUM WORKPIECES WITHOUT SIMULTANEOUSLY RAPIDLY ETCHING THE WORKPIECE BY SUBJECTING THE WORKPIECE TO A SOLUTION IN WATER OF FROM 2 TO 10 POUNDS PER GALLON OF THE MIXTURE CONSISTING ESSENTIALLY OF SODIUM OR POTASSIUM NITRITE, 2-25 WEIGHT PERCENT, SODIUM OR POTASSIUM GLUCONATE 2-25 WEIGHT PERCENT, SODIUM OR POTASSIUM NITRATE, 2-25 WEIGH PERCENT, AND SODIUM HYDROXIDE, BALANCE TO 100 WEIGHT PERCENT, E.G., BY IMMERSING THE WORKPIECE IN AN ELEVATED TEMPERATURE BATH AT TEMPERATURES BETWEEN ABOUT 200*F. AND 300*F.

TL;DR: A sensitive and rapid method was developed for the determination of ruthenium in faces and other products of digestion by ruminants and is suitable for the determined at concentrations between 5 and 50 µg per gram of dry matter.
Abstract: A sensitive and rapid method was developed for the determination of ruthenium in faces and other products of digestion by ruminants. The sample was ashed at 350 °C with a mixture of potassium nitrate and potassium hydroxide, dissolved in dilute nitric acid and analysed by atomic-absorption spectrophotometry using a carbon rod atomiser. The method is particularly free from interferences and is suitable for the determination of ruthenium at concentrations between 5 and 50 µg per gram of dry matter.

TL;DR: A theoretical and experimental study of an AT-cut quartz crystal resonator as a sensor for viscous conductive liquids has been performed in this paper, where a novel continuous flow cell system and an 11 MHz quartz crystal were used for the experiments.
Abstract: A theoretical and experimental study of an AT-cut quartz crystal resonator as a sensor for viscous conductive liquids has been performed. A novel continuous-flow cell system and an 11 MHz quartz crystal were used for the experiments. Results are presented for aqueous dilute solutions of potassium chloride (KCl) and potassium nitrate (KNO3).

TL;DR: The compound organic fertilizer has excellent slow-release property and can effectively improve the yield and quality of crops as mentioned in this paper. But, it is not suitable for rice planting as it is unsuitable for rice harvesting.
Abstract: The invention discloses compound organic fertilizer used for rice planting and having the high slow release property. The compound organic fertilizer is prepared from raw materials as follows: ammonium nitrate, monopotassium phosphate, urea, urea phosphate, calcium superphosphate, ammonium dihydrogen phosphate, potassium sulfate, magnesium sulfate, potassium nitrate, amino sodium dicarboxylate, trichoderma, yeast powder, a straw fermentation agent, cellulase, potassium mineral powder, mica powder, chitin, talc, turf powder, fly ash, conch powder, furfural residues, rice hull powder, poultry manure, corn straw, rapeseed cakes, dolomite, diatomite, calcite, humic acid, lignin, sodium bentonite, EDTA chelate, amino acid chelate, dicyandiamide, phosphoryl triamide, a slow release agent and a soil conditioning agent. The invention further provides a preparation method of the s compound organic fertilizer used for rice planting and having the high slow release property. The compound organic fertilizer has excellent slow release property and can effectively the yield and quality of crops.
