Study on the effect of hydrogen addition on ignition and combustion of prechamber ignition system [PDF]
The gas engine for the cogeneration system realizes lean combustion by using prechamber ignition. The fuel properties of natural gas are quantified as methane value, and a small amount of H2 and C2-C4 hydrocarbon fuels affect ignition and combustion ...

Optical investigation of prechamber combustion in an RCEM [PDF]
In this study, detailed investigations of scavenged prechamber engine combustion are performed experimentally in a Rapid Com-pression Expansion Machine (RCEM), which allows optical access into the main chamber. OH* chemiluminescence measurements combined with pressure measurements are used to study the effect of varying ignition timing on combustion ...

Risk factors, treatment, and outcome in dogs and cats with subdural hematoma and hemispheric collapse after ventriculoperitoneal shunting of congenital internal hydrocephalus. [PDF]
Abstract Background Overshunting and hemispheric collapse are well‐known complications after ventriculoperitoneal shunt (VPS) implantation. Risk factors that predispose to overshunting, treatment options, and prognosis after therapeutic intervention have not been described.

Different Reactions Define the Electrochemical Window in 1-Butyl-3-Methylimidazolium Triflate on Gold and Platinum Electrodes. [PDF]
Ionic liquids have attractive features such as a large electrochemical window. It is shown that it depends on both the electrolyte and electrode when water is added to an imidazolium ionic liquid. Ionic liquids (IL) make excellent candidates for many energy storage devices due to unique and tunable properties such as a large electrochemical window (ECW)

Ectopic Expression of T-Box Transcription Factors Alters Mouse Forelimb Formation. [PDF]
ABSTRACT The developing vertebrate forelimb expresses seven T‐box transcription factors, with several in overlapping expression domains. All T‐box transcription family members share similarity within their DNA binding domain, the T‐domain. Outside of the T‐domain, these factors share little similarity, allowing family members to have different ...
