Title: Obstacles Encountered by Students in Understanding Basic Concepts of Physics and New Teaching Approaches to Overcome Them Authors: Rafiu, A. A; Adetona, A. A Abstract: Individual teachers of college level physics sometimes develop deep insights into how their students learn and what elements of classroom instructions are available in facilitating the learning process. Yet these insights rarely persist beyond the individual instructor. Educational methods seem to cycle from one fad to another, rarely cumulating increasingly powerful knowledge in the way scientists expect understanding to grow. In this paper we explore the characteristics of us understand of physical world and of our teaching about it. The critical factor is using ‘the culture of science’ the set of processes that allow us to build a community consensus knowledge base. Elements of the beginning of a base for our educational knowledge are discussed and examples given from disciplined-base physics education research.

Title: Delineating the Regional Gold Mineral Veins within Wawa (Sheet 128) and Kubil (Sheet 159) Niger State, Nigeria, North Central Nigeria Authors: Alhassan, U.D; Lawrence, J.O; Alkali, A Abstract: Aeromagnetic data subjected to various filtering method: Analytical Signal, First Vertical Derivatives(FVD) and Center for Exploration Targeting (CET). was used to delineate the geological structures that could serve as host to gold within Wawa (Sheet 128) and Kubil (Sheet 159) Niger State, Nigeria. The area is bounded by Latitude 4º00' and 4º30E' to Longitude 9º30' and 10º30'N. The total magnetic intensity map comprises of both positive and negative anomalies with magnetic values within the study area ranges from -66.589 nT to 129.237 nT. The result of the FVD and CET revealed magnetic lineaments in SW-NE direction that could serve as gold veins around latitude 9o50' to 10º10'N within Yangari, Lasun Sarabe, Wawa Malete town down to Doro across river Yakumosin. The major lineament are mapped as F1 to F7 on the first vertical derivatives

Title: EFFECT OF HIGH CONCENTRATION OF eTh AND eU WITHIN PART OF NORTH CENTRAL NIGERIA ON GEOTHERMAL PARAMETERS Authors: Rafiu, A.A; Alkali, A Abstract: The study deployed aeromagnetic data to estimate geothermal potential and radiometric concentration data to evaluate the radiogenic heat in parts of Kaduna state, central Nigeria. The study area which has been noted for relative high concentration of Potassium (K), Uranium (eU) and Thorium (eU) within Nigeria is bounded by latitude 10°00' to 10°30' and longitude 7°30' to 8°30', an area of 6,050 km2. The modified Curie depth method was employed in evaluating the Curie depth, geothermal gradient and heat flow. The region is found to have its shallow Curie point depth of 8.43 km below Wugana. The heat flow of the study area has values ranging from 81.9 mW/m2 to 171.9 mW/m2 with an average value of 167.8 mW/m2. The geothermal gradients range from 32.76 to 68.8 degrees Celsius per kilometre, with an average of 67.16 degrees Celsius per kilometre. Results of radionuclide concentrations revealed that the northern central regions extending down to the central part of the study area recorded medium to high values of radiogenic heat flow in the range of 3.85 to 4.5 μW/m3. Correlating the result of geothermal potential with radiogenic heat production reveals that regions of low Curie point depth correspond to regions of medium to high radiogenic heat production. Hence, the regions of significant geothermal potential are the mid-northern and mid-western areas such as Wugana, New Kwasan, and down to Ron village.The geology consist of rocks such as Pophyritic Granite Biotite granite, medium-to-coarse grained Younger Basalt, and granite gneiss, these in-situ basement rocks has undergone structural deformation and weathering which account for high concentration of radionuclide which exhibit radioactivity and consequently generate heat at the subsurface.

Title: Crustal Structure and Modelling of parts of Anambra Basin Nigeria, using Bouger gravity data Authors: Lawrence, Jane Osita; Udensi, Emmanuel Emeka; Salako, Kazeem Adeyinka; Alkali, A; Abdullahi, Muhammad; Adewumi, Taiwo Abstract: The bouguer gravity map covering the study area were digitized, merged, contoured and subjected to Spectral depth analysis and Two-dimensional (2-D) gravity Modeling to determine the crustal structure and Mohorovicic Discontinuity beneath parts of Anambra Basin, Nigeria. Nine Spectral sections and four two-dimensional (2-D) gravity Models were constructed for the study area bounded by Longitudes 5° 00' to 6°00' E and Latitudes 6° 00' to 7° 00' N as with gravity data, relationship between crustal structure and crustal density can be established. With the Bouguer gravity anomalies and the available geological and geophysical information for the study area. The obtained results indicates that: 1) the migmatitic crust is underlain by upper mantle. 2) The highest sedimentary thickness for the study area is about 14.5 km- a good sign for mineral exploration. 3) the crustal thickness ranges from 31.0 km to 41.5 km. 4) The average densities for the different rock layers are: 2.623 g/cm3 for sediments, 2.65g/cm3 for the crustal layer, and 3.2 g/cm3 for the upper mantle
