MEASUREMENT OF NITRATE-NITROGEN CONCENTRATION IN SOIL BASED ON ABSORPTION SPECTROSCOPY
MJ Preiner, NC Koshnick, JS White, JP Strachan – US Patent 20,160,146,728, 2016 The nitrate-nitrogen concentration in soil is estimated based on the nitrate-nitrogen 200 nm absorption peak. In one embodiment, a device measures the attenuation spectrum of a...Optical fiber sensor for low dose gamma irradiation monitoring
AI de Andrés, Ó Esteban, M Embid – Sixth European Workshop on Optical Fibre …, 2016 An optical fiber gamma ray detector is presented in this work. It is based on a Terbium doped Gadolinium Oxysulfide (Gd2O2S:Tb) scintillating powder which cover a chemically...Formation mechanism of toxic-element-free oxide layer on Ti–6Al–4V alloy in d.c. glow discharge plasma with pure oxygen gas
K Satoh, S Sato, K Wagatsuma – Surface and Coatings Technology, 2016 The purpose of this study is to elucidate the formation mechanism of a toxic-element-free oxide layer on a Ti–6Al–4V alloy by using d.c. glow discharge plasma in pure oxygen atmosphere, which...Mixing effects on light exposure in a large-lake epilimnion: A preliminary dual-dye study
EC Minor, JA Austin, L Sun, L Gauer, RC Zimmerman… – Limnology and …, 2016 Light plays a critically important role in driving photo- and biogeochemistry of aquatic systems, and our ability to measure and model submarine light fields is fairly sophisticated....
