We reviewed the various sub-sectors of the Nigerian transport sector with their corresponding energy consumption rates. Results show that all the sub-sectors are solely dependent on fossil fuels to meet their energy demands and requirements, thus mak

The major cause of deterioration in lead-acid batteries is sulfation. There are patents on the use of high-frequency pulse desulfators to desulfate lead-acid batteries. Also, many products available in the market worldwide claim to use this technique

We present polarization observations of 28 compact steep-spectrum sources made with the upgraded MERLIN at 5 GHz. With an angular resolution of 60 milliarcsec and rms noise levels of about 0.1 mJy beam−1, the total intensity images reveal new detai

We present new high-resolution MERLIN and VLA maps of the quasar 1150+497 which has a bright jet with compact knots and sharp bends, but no prominent hotspot. The source shows very little variation of Faraday rotation or depolarization. We discuss wh

We present an EVN map at 1.67 GHz and combined EVN-MERLIN maps at 1.67 and 5 GHz of the compact steep-spectrum radio source 3C147. The maps reveal three dominant extended regions and a bright core. The structure cannot be readily explained with the s

We present high-resolution observations of steep-spectrum radio sources made with MERLIN at 5 GHz. Thirty-one objects, comprising 11 quasars and 20 galaxies, most of them being Compact Steep-Spectrum sources (CSSs), have been mapped with resolutions

New VLA, MERLIN, and VLBI observations are presented for 3C380, a powerful compact steep-spectrum radio source with complex extended structure, and an attempt is made to clarify whether it is a larger source seen end-on or whether it is intrinsically

It is now generally agreed that if quasars and nearby low redshift galaxies are associated, then there should be luminous connections between them. However, most of the observational evidence being presented is in the optical domain, whereas such evi
