The 12-pulse diode rectifier (12-PDR) fails to comply with the limits of total harmonic distortion (THD) of supply current to be less than 5% specified in the IEEE Standard 519.Passive harmonic suppression circuits (PHSCs) have been observed to be a viable and cost-effective solution to improve the THD of AC-mains current at a reduced cost.PHSCs La
Fish play a crucial role in the estuarine ecosystem due to their ecological and commercial significance.Consequently, it is essential to study the characteristics of fish communities and their impacts within the estuary.In this study, we employed a single-boat bottom trawl to conduct four fishery resource surveys in April (spring), August (summer),
This study explored spatio-temporal patterns influencing reef fish richness and abundance in two coastal islands within marine protected areas (MPAs) in southeastern Brazil.Data were collected using a remotely operated vehicle (ROV) during the 2022 seasonal cycle, with samples taken day and night.A total of 16 661 individuals from 81 species was re
Mycobacterium tuberculosis synthesises isoprenoid precursors via the MEP/DOXP pathway and at least five enzymes in the pathway (Dxs1, Dxr/IspC, IspD, IspF, and GcpE/IspG) are required for growth in vitro.We investigated the role of LytB (IspH) in M.tuberculosis; M.tuberculosis is unusual in that it has two homologs-LytB1 and LytB2.We were unable to
Since 1965, the number of cities constructing and operating sewerage systems had been on the rise, with waterway overhaul now prevalent in many parts of Japan.However, as the number of facilities under management has increased, their decrepitness has become obvious.The average service life of sewer pipe has been determined to be 50 years, but in Co
