Ignition

2018
Every process of transformation—human, institutional, or community—begins with the stage of consciousness. Can we evolve without being fully aware of what we want to achieve? Of course! However, this implies going as a wind vane, waiting for the wind to indicate the direction to follow, with the respective risks and consequences of lack of control or ...

Igniting adipocyte thermogenesis

Cell, 2022
Maintenance of body temperature is intimately tied to energy expenditure and body weight regulation. In this issue of Cell, Li, Wang, et al. discovered that localized hyperthermia induces the thermogenic program to increase energy expenditure and decrease body weight in mice and humans.

Inertial Confinement Fusion with Advanced Ignition Schemes: Fast Ignition and Shock Ignition

2013
Essential ingredients of inertial confinement fusion (ICF) are fuel compression to very high density and hot spot ignition. In the conventional approach to ICF both fuel compression and hot spot formation are produced by the implosion of a suitable target driven by a time-tailored pulse of laser light or X-rays.

HM-60 pyrotechnic igniters ignition improvement

26th Joint Propulsion Conference, 1990
For the start and ignition equipment (a turbo pump starter and two igiters) of the HM60-Vulcain, the main engine of Ariane 5, Europe's future launcher, special propellants based on ampsaiurr nitrate have been developed. As the ignition of such propellants is more sensitive to the well known igition parameters than most other propellants, a special ...

Theory of ignition and auto-ignition

Combustion and Flame, 1962
Abstract A fuel-oxidant system may auto-ignite, be ignited by a source, or remain non-inflammable depending upon the ambient temperature, pressure, composition, geometry of the container, etc. This paper presents a theoretical attempt to explain how all these observed phenomena can occur in a given chemical system.
