In order to find out the cause of such damage, the samples of pipes were taken at the places where the most damage took place. Samples were taken in the form of film, sediment and/or sludge from inner and the outer surface of the pipes. As well as each pieces of pipes were further cut into 10 mm x 10 mm plates. The prepared samples were studied using X-ray diffraction, X-ray emission spectrometry, scanning electron microscope and microanalysis as well as a light microscope. The results implicate microstructural changes within the inner wall of the pipe which was caused by intercrystalline corrosion. Such corrosion in the investigated samples of sediment and/or sludge appeared due to the damage of the protective film during the aggressive phases,展开更多

The embrace of storytelling in the digital realm by these young minds reflects the interplay of traditional culture, western modernism, and changes brought about by media industries. These women have adopted and used new media as a vehicle to maneuver their interesting and fresh ideas and have seen the rectilinear screen of a computer as an exit through which to come out and say something to the masses. The thinking methodology has culminated in pragmatic and dynamic visuals in order to celebrate, inform, and create awareness about the issues that they see in the region and among the people. With this freedom of expression, they are creating a new visual culture and transforming themselves into a meaningful workforce. With emerging technological tools, they blend intuitive, pragmatic, emotional, and contextual imagination with a highly-sophisticated production pipeline in order to incorporate the challenges of synthesizing ＂dialect＂ and ＂codes＂ that have traditionally been segregated in the culture.

It is found that the cross sections of these two processes could reach a few Fo with reasonable parameter values. With the yearly integrated luminosity of L 500 fb-1 expected at the ILC, one could collect hundreds up to thousands of charged ttiggs events via these two processes. Therefore, our researches in this paper can help us search for charged Higgs bosons, and furthermore, to test the LRTH model.展开更多
