Experimental Study on the Combustion and Explosion Characteristics of Tributyl Phosphate and Kerosene Mixtures at Different Initial Pressures in High‐Temperature Environments

open access: yesEnergy Science &Engineering, EarlyView.
The explosion hazard of TBP and kerosene mixed vapor in the nuclear fuel reprocessing process is studied. The results enrich the explosion characteristics and explosion limits of TBP‐kerosene, and provide reference value and basis for the safety setting of the operation process and operating environment of nuclear fuel reprocessing plants ABSTRACT As ...

Decadal Changes of UV Aerosol Optical Depth in Hobart, Australia Measured With a Brewer MKIII: Relationship to Bushfire Events and Climate Indices

open access: yesInternational Journal of Climatology, EarlyView.
Monthly average aerosol optical depth at 320 nm obtained with a Brewer MKIII spectrophotometer for Hobart, Australia (42.8806° S, 147.3250° E) over a 21‐year period. There is a linear trend of 15.4% per decade. There are 9 months when the average aerosol optical depth exceeds twice the monthly standard deviation.

Resistance ofBacillusEndospores to Extreme Terrestrial and Extraterrestrial Environments [PDF]

open access: yesMicrobiology and Molecular Biology Reviews, 2000
SUMMARYEndospores of Bacillus spp., especially Bacillus subtilis, have served as experimental models for exploring the molecular mechanisms underlying the incredible longevity of spores and their resistance to environmental insults. In this review we summarize the molecular laboratory model of spore resistance mechanisms and attempt to use the model as
