the quality of pressure distribution over the atmosphere of the sea level and geopotential altitude at different atmosphere layers affect on many climate and meteorology phenomena of the earth surface. one of the important meteorology phenomenon is the occurrence of frost phenomenon especially late spring frost. in this surrey, occurring late spring frost days and minimum temperature during the...

In this research, the high-energy planetary mill was employed to produce nanocrystalline Ti-50Al(γ)(at%) powders. Initial powders were mechanically alloyed in 99.9999% and 90% purities of Argon and also Air atmosphere with alloying times up to 50h. The effect of impurity of Argon atmosphere on the microstructure and the rate of phase transformation of Ti-50Al were investigated during mechanical...

Carrier’s novel was published in the same year as Nègres blancs d’Amérique by Pierre Vallières and it relies on dialectics between colonizer colonized that prevalent Québécois narrative prose 1960s. While being grounded this cultural context, Carrier transforms dialectic setting his a rural environment against background of World War II (the visitation fallen French-Canadian soldier whose remai...
