Journal ArticleDOI
Distinguishing Gasoline Engine Oils of Different Viscosities Using Terahertz Time- Domain Spectroscopy
TL;DR: In this article, a linear regression was applied to refractive index data at 025-THz intervals from 05 to 20THz to predict kinematic viscosity.
Journal ArticleDOI
Nonthermal pasteurization of tender coconut water using a continuous flow coiled UV reactor
Dibash Gautam,Arosha Loku Umagiliyage,Rajiv Dhital,Prabesh Joshi,Dennis G. Watson,Derek J. Fisher,Ruplal Choudhary +6 more
TL;DR: In this paper, the antimicrobial effectiveness of ultraviolet light C (UVC) as a non-thermal pasteurization of TCW was evaluated using a dean flow ultraviolet reactor with wavelength of 254nm.
Journal ArticleDOI
Absorption Wavebands for Discriminating Oxidation Time of Engine Oil as Detected by FT-IR Spectroscopy
TL;DR: In this paper, Fourier Transform-Infrared (FT-IR) spectroscopy was used to analyze gasoline engine oil (SAE 5W20) samples that were exposed to seven different oxidation times (0 h, 24 h, 48 h, 72 h, 96 h, 120 h, and 144 h) to determine the best wavenumbers and wavenumber ranges for the discrimination of the oxidation times.
Journal ArticleDOI
Detection of charcoal rot (Macrophomina phaseolina) toxin effects in soybean (Glycine max) seedlings using hyperspectral spectroscopy
Ameer Al-Ahmadi,Arjun Subedi,Guangxing Wang,Ruplal Choudhary,Ahmad M. Fakhoury,Dennis G. Watson +5 more
TL;DR: This study exposed soybean seedlings to a culture filtrate of M. phaseolina containing toxin(s) produced by the fungal pathogen, and proposed the 1940 nm ratio at 24 h as a relative measure of charcoal rot susceptibility of soybean varieties.

Method of and apparatus for spraying foliar composition
TL;DR: In this article, a spray stream of liquid composition at 10 to 75 pounds per square inch pressure from an orifice having a cross-sectional area of from about 0.0000948 to approximately 0.0323000 square inches to strike vegetation foliage within from about 5 to about 15 inches, with a plurality of gas-directing vents spaced-apart on opposite sides of the orifice but not circumscribing the spray stream within the 5 to 15 inches.
