Methods and systems are provided for displaying and forecasting the lithology and wellbore conditions to be encountered while conducting drill string operations in a wellbore. The use of the semiconductor film manufactured in this manner allows manufacturing of a semiconductor device with good electrical characteristics only by hydrogenating treatment even when the activation of impurity elements does not carried out. The LNT may be located ahead of the DPF in the exhaust line. The reinforcement plate may be formed in various shapes. We can expect that the video compressed data size or the video transmission speed is reduced accordingly to a ratio of \u2153 can be regenerated from the corresponding R, G, B), thus storage memory and transmission bandwidth can be reduced considerably without degrading the visual perception of the video quality on the proprietary VP display.
