Flame Instability and Transition to Detonation in Supersonic Reactive Flows

open access: yes, 2017
Multidimensional numerical simulations of a homogeneous, chemically reactive gas were used to study ignition, flame stability, and deflagration-to-detonation transition (DDT) in a supersonic combustor.

An Assessment of Gypsy Moth Eradication Attempts in Michigan (Lepidoptera: Lymantriidae) [PDF]

open access: yes, 2017
Michigan\u27s infestation of gypsy moth, Lymantria dispar, extends over 600,000 acres, First discovered in Michigan in the 19505, gypsy moth was reportedly eradicated through the use of DDT then reintroduced in the 1970s, Substantial circumstantial ...

Soil Sulfur and Nitrogen Affect Wheat Flour Mixing Characteristics and Protein Features in Flour and Dough

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Sulfur and nitrogen affect wheat yield and the protein content and quality. Hard red spring wheat (Albany cultivar) grown under six different soil nitrate application levels (0, 60, 120, 180, 240, and 300 lbs/acre) and two sulfur levels (0 or 20 lbs/acre) was used.

Sexual conflict maintains variation at an insecticide resistance locus [PDF]

open access: yes, 2015
Background: The maintenance of genetic variation through sexually antagonistic selection is controversial, partly because specific sexually-antagonistic alleles have not been identified. The Drosophila DDT resistance allele (DDT-R) is an exception.

DDT degradation efficiency and ecotoxicological effects of two types of nano-sized zero-valent iron (nZVI) in water and soil.

open access: yesChemosphere, 2016
Nano-scale zero-valent iron (nZVI) has been conceived for cost-efficient degradation of chlorinated pollutants in soil as an alternative to e.g permeable reactive barriers or excavation.

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Dynamic Reactivity: Reversible Reaction of a Phosphinine–Borane Adduct With Water and Double Hydrophosphination

open access: yesChemistry – A European Journal, EarlyView.
A phosphinine–borane Lewis pair shows a dynamic mode of water addition, revealing reversible and regioselective transformations that expand the reactivity of aromatic phosphorus heterocycles and open pathways to stimuli‐responsive systems for catalysis, small‐molecule activation, and functional materials.

Constraints On The Delayed Transition to Detonation in Type Ia Supernovae

open access: yes, 2000
We investigate the possibility of a delayed detonation in a type Ia supernova under the assumption that the transition to detonation is triggered by turbulence only.
