Solar wind and geomagnetic activity during two antagonist solar cycles: Comparative study between the solar cycles 23 and 24

To better understand the geomagnetic conditions and the particularities of solar cycles 23 and 24, we present analysis from morphological variations of solar and geomagnetic activities parameters IMF-Bz, the interplanetary electric field (E), the proton density (N), Dst (disturbance storm time), Polar cap (PC) indices (PCN and PCS), and geomagnetic activity index aa. The occurrences of the different classes of...

Combined application of vertical electrical sounding and 2D electrical resistivity tomography for groundwater exploration in parts of Enugu metropolis, Southeastern Nigeria

Vertical electrical sounding (VES) and 2D electrical resistivity tomography (ERT) employing the Schlumberger and Wenner configurations respectively were combined for groundwater exploration in parts of Enugu metropolis. The area is underlain by Enugu Shale and Mamu Formation. A total of twenty (20) VES and four (4) 2D ERT traverses were acquired in the study area. VES and 2D ERT data were processed and interpreted using...

Mineralogical evaluation of clay deposits of Nanka formation in parts of South-eastern Nigeria

Detailed field geology and laboratory studies of the Eocene Nanka Formation were carried out where they outcropped in places like Ogbunike, Umunya, Nanka, Ekwulobia and Ogbu all in Anambra State, South-eastern Nigeria to determine their mineralogical composition. Samples of clay and unconsolidated sands were collected from outcrop locations within the formation and subjected to X-ray diffraction and granulometric...

Uncooled PV cell under variable light concentration: Determination of profiles of the temperature, the intrinsic properties and the carrier density

Studies on concentrated light influence do not take into account the effect of the heating and this proves to be harmful on photovoltaic parameters. The main purpose of this work is to study the effects of light concentration and the heating caused by this concentration on intrinsic properties and carrier density profile. A thermal model of the PV cell is proposed. By applying the power balance at the steady-state, the...
