THE INFLUENCE OF THE COAL DUST COMPOSITION ON THE PROPAGATION SPEED OF THE COMBUSTION FRONT OF THE COAL DUST WITH AN INHOMOGENEOUS PARTICLE DISTRIBUTION IN THE AIR

The problem of the combustion of a gas suspension with an inhomogeneous distribution of particles over space occurs exists for the coal dust suspension combustion in combustion chambers and burners.The inhomogeneous distribution of particles in space can significantly affect the combustion velocity of the aerosolve of coal dust.The purpose of the p

In a five-year field experiment on a well-limed sandy soil five nitrogen fertilizers were compared.They were urea, ammonium sulphate, calcium nitrate, calcium Wheel Transport Kit ammonium nitrate and a mixture of ammonium sulphate and calcium nitrate.The crops in successive years were spring wheat, winter rye, winter wheat, spring wheat and winter

Abstract Glioma is the most common and fatal primary brain tumor in Ceiling Fan Light Kit humans.Myosin binding protein H (MYBPH), which was first identified as an important myofibrillar constituent of vertebrate skeletal and cardiac muscles, reduces cell motility and metastasis.However, its role in gliomas remains unclear.We evaluated the expressi
