Impact of chlorine ion chemistry on ozone loss in the middle atmosphere during very large solar proton events

Autor: M. Borthakur, M. Sinnhuber, A. Laeng, T. Reddmann, P. Braesicke, G. Stiller, T. von Clarmann, B. Funke, I. Usoskin, J. M. Wissing, O. Yakovchuk

Publikováno v: Atmospheric Chemistry and Physics, Vol 23, Pp 12985-13013 (2023)

Solar coronal mass ejections can accelerate charged particles, mostly protons, to high energies, causing solar proton events (SPEs). Such energetic particles can precipitate upon the Earth's atmosphere, mostly in polar regions because of geomagnetic

Determination of Hydrazine in Maleic Hydrazide Technical and Pesticide Formulations by Gas Chromatography: Collaborative Study

Autor: David G Tutty, David M. Borth, Wan S Yu, Anthony S Riggs

Publikováno v: Journal of AOAC INTERNATIONAL. 91:5-12

Twelve collaborating laboratories assayed hydrazine in technical maleic hydrazide (MH), 6-hydroxy-2H-pyridazin-3-one, and 2 formulated products, a liquid concentrate and a soluble granule, using gas chromatography (GC) with electron capture detection

Liquid Chromatographic Determination of Maleic Hydrazide in Technical and Formulated Products: Collaborative Study

Autor: David M. Borth, Dora Y Lau, James L Mertz

Publikováno v: Journal of AOAC INTERNATIONAL. 89:929-936

Fourteen collaborating laboratories assayed maleic hydrazide (MH), 6-hydroxypyridazin-3(2H)-one, in technical and formulated products by reversed-phase liquid chromatography (LC) with sulfanilic acid as an internal standard. The active MH in the samp

Confidence limits for normal type I censored regression

Autor: Michael S. Wilhelm, David M. Borth

Publikováno v: Chemometrics and Intelligent Laboratory Systems. 63:117-128

A new method for calculating confidence limits for regression analysis using normal Type I censored data is presented. The new method is compared to two existing methods via a simulation study. Over a variety of examples, the new method consistently

Insecticidal, Miticidal, and Ovicidal Activity of 5,6-Dihydro-4H-1,3,4-Oxadiazines

Autor: David M. Borth, Gilbert W. Angle, Paul T. McDonald, Mark A. Dekeyser, Roger G. H. Downer

Publikováno v: Journal of Economic Entomology. 86:1339-1343

Dihydrooxadiazines, conformationally restricted analogs of octopamine, were toxic to eggs of twospotted spider mites, Tetranychus urticae (Koch): to eggs of tobacco budworms, Helicoverpa virescens (F.); and to adult rice delphacids, Sogatodes orizico

Quantitative structure-activity relationships in acaricidal 4H-1,3,4-oxadiazin-5(6H)-ones

Autor: Anupama Mishra, David M. Borth, Richard C. Moore, Mark A. Dekeyser

Publikováno v: Journal of Agricultural and Food Chemistry. 39:374-379

A series of 37 2,4-diphenyl-1,3,4-oxadiazin-5-one acaricides has been synthetized. Their acaricidal activity has been related to certain of their physicochemical properties by using a Hansch-type regression equation. The initial equation developed wa
