Increasing arc pressure by tens of times with fine pouring tube, a positive shock wave the entering closed space thin tube (electric recoil wave). The electric is 8 to 23 than that wave. Since has more wave, and their directions are opposite, poring driven away from channel completely emptying large scale truncation formed. Therefore, interrupts lightning current, recombusts form new backwash r...

This article presents the first systematic study of spatial transmission 1929–33 epidemic meningococcal meningitis and its association with local coal mining communities in three adjacent high incidence counties England; Nottinghamshire, Derbyshire, West Riding Yorkshire. Drawing on a robust method epidemiological analysis (swash-backwash model), we demonstrate gradient response levels employme...

The use of powdered activated carbon for fouling control in the membrane processes is limited by some secondary problems associated with its use, like cake formation, long backwash times and blackening of pipes. Granular activated carbon (GAC) was used as an alternative of powdered activated carbon due to its large particle size which was kept from being entering into the membrane system. The s...
