In this study, we obtained over 4,000 transposon mutants of Mycobacterium vanbaalenii PYR-1 and analyzed one of the mutants, 8F7, which appeared to lose its ability to degrade pyrene while still being able to degrade fluoranthene. This mutant was identified to be defective in nidA, encoding an aromatic ring-hydroxylating oxygenase (RHO), known to be(More)
This thesis proposes two new preamble structures for synchronization and cell searching in cellular based Orthogonal Frequency Division Multiplexing (OFDM) systems. The proposed preamble structures are to impose Pseudo Noise sequences (PN-sequences) on the OFDM transmitted signal in time-domain for time and frequency synchronization. This scheme make it(More)
The methodology provided by the Intergovernmental Panel on Climate Change (IPCC) guidelines is widely used for estimating enteric methane (CH4) production by cattle. No attempt other than the default values in the IPCC Tier 1 has been made for estimating CH4 emission from Hanwoo, a dominant beef species in Korea raised in a unique feeding system. The(More)
