Deep ice core drilling to a depth of 3035.22 m at Dome Fuji, Antarctica in 2001–07
Annals of Glaciology, 2021 The Japanese second deep ice coring project was carried out at Dome Fuji, Antarctica. Following the drilling of the pilot hole in 2001, deep ice core drilling led by the Japanese Antarctic Research Expedition (JARE) was conducted over four austral summer

Turbine Engine Icing and Ice Detection [PDF]
ASME 1972 International Gas Turbine and Fluids Engineering Conference and Products Show, 1972 A review of conditions necessary for turbine engine icing is presented along with the potential problems caused by engine icing. Methods of protecting the engine against icing are briefly presented and a method of automatic anti-ice operation is proposed.

IC engine and environment [PDF]
Vojnotehnicki glasnik, 2002 Ecological trends and movements in the modern world grow stronger and more active, due to a real danger of Earth pollution. One of the main sources of pollution are 1C engines and their influence on environment is significant. However, conventional combustion engines still are and will be dominant powering systems for numerous future applications.

Detecting Clouds Associated with Jet Engine Ice Crystal Icing [PDF]
Bulletin of the American Meteorological Society, 2019 AbstractIn the past two decades, more than 150 jet engine power-loss and damage events have been attributed to a phenomenon known as ice crystal icing (ICI). Ingestion of large numbers of ice particles into the engine core are thought to be responsible for these events, which typically occur at high altitudes near large convective systems in tropical ...

An Overview of NASA Engine Ice-Crystal Icing Research [PDF]
SAE Technical Paper Series, 2011 <div class="section abstract"><div class="htmlview paragraph">Ice accretions that have formed inside gas turbine engines as a result of flight in clouds of high concentrations of ice crystals in the atmosphere have recently been identified as an aviation safety hazard. NASA's Aviation Safety Program (AvSP) has made plans to conduct research

Angle of repose of granulated ice: effect of wood ash
Journal of GlaciologyNew experiments have revealed that the addition of a small amount of wood ash doubles the angle of repose of granulated ice at −10°C, but has little effect at −30°C. It is hypothesized that this behavior may be explained in terms of the freezing of water

The contribution of wood burning and other pollution sources to wintertime organic aerosol levels in two Greek cities [PDF]
Atmospheric Chemistry and Physics, 2017 The composition of fine particulate matter (PM) in two major Greek cities (Athens and Patras) was measured during two wintertime campaigns, one conducted in 2013 and the other in 2012.

Cyclic strengthening of lake ice
Journal of Glaciology, 2021 Further to systematic experiments on the flexural strength of laboratory-grown, fresh water ice loaded cyclically, this paper describes results from new experiments of the same kind on lake ice harvested in Svalbard. The experiments were conducted at −12
