3.6 Conclusion A novel fully automated continuous-flow plunger-in-needle liquid phase microextraction (PIN-LPME) technique with gas chromatography/mass spectometric (GC/MS) analysis to determine five organochlorine pesticides (OCPs) from water samples was develop[r]
That future looked a lot brighter for conductive polymers in the 1980s. Probably the most significant commercialization of conductive polymers was for flexible, long- lived batteries that were produced in quantity by Bridgestone Corp. and Seiko Co. in Japan and by BASF/Va[r]
3-1. Short Circuit Transfer 1 Short Circuit Transfer Short circuit transfer refers to the welding wire actually “short circuit- ing” (touching) the base metal be- tween 90 - 200 times per second. With short circuit transfer, wire feed speeds, voltages, and deposition rates are usually lower than[r]

This paper presents the results of investigation on water quality in Ninh Binh coastal area in 2015. The results show that the risk quotient of water quality of the area was 0.34, indicating the water was safe for aquatic life.
Other preventive measures can be taken to minimize the deleterious effects of sulfides (Ref 48, 49, 50). Elimination of decaying plant and animal life from inlet pipes and channels can alleviate the effects of sulfate-reducing bacteria. Initial design or operational procedu[r]
