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 ...

Normal pressure hydrocephalus is a preventable and treatable cause of dementia. A telemetric prechamber allows individually tailored ventriculoperitoneal shunt valve adjustments in patients treated with the shunting procedure.In this pilot, prospective randomized trial, 33 adult patients were divided into Group A (with an implanted telemetric ...

Effect of Dimensions of Prechamber on Lean Burn Gas Engine.
The effect of the dimensions of a prechamber was researched using a medium-sized single-cylinder engine. The air-fuel ratio, A/F, in the prechamber changed quickly, when only gas was supplied to the prechamber. The amount of gas supplied, ignition timing, and A/F in the main chamber were affected by A/F in the prechamber at ignition timing.

Flow characteristics of a motored spark ignition engine with a prechamber.
To understand the effect of a torch jet on the flow characteristics in a prechamber spark ignition engine, a laser Doppler anemometer (LDA) is used to measure the velocity in a main chamber under the motored condition. The engine is operated at a constant speed of 1000 rpm with a wide open throttle (WOT).

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)
