Physics Discussion Questions

Semiconductors are substances with electrical conductivity characteristics halfway between insulators and conductors. They are the basis for devices like transistors, diodes, and integrated circuits, crucial parts of contemporary electronics. The capacity to conduct electricity under certain circumstances, such as an applied voltage or exposure to light, defines semiconductors. Semiconductors can have their conductivity altered and regulated, unlike conductors, which have high conductivity, a...

Reservoir Characterization and Volumetric Analysis of Lona Field, Niger Delta, Using 3-D Seismic and Well Log Data

ABSTRACT  An integrated 3-D seismic data, checkshot data and a suite of four well log located at the Lona field, Niger Delta were analysed with Petrel software for reservoir characterization and volumetric analysis of the field. The method adopted involves petrophysical analysis, structural analysis, volumetric analysis and reservoir classification. Detailed petrophysical analysis revealed three reservoirs.Average reservoir parameters such as porosity (0.25), gross thickness (27 m), hydrocar...

Interpretation of High Resolution Aeromagnetic Data over Okigwe and some Adjoining Areas, South Eastern Nigeria.

ABSTRACT  Digitized high resolution total field aeromagnetic data over Okigwe and environ (Sheet 312) was interpreted using the standard 3-D Euler de-convolution and spectral analysis in order to determine depth to the magnetic basement, delineate the basement topography and relief, and delineate the trend of the structural features associated with the basin. The aeromagnetic data were subjected to various data enhancement and transformation routines using the Geosoft Oasis MontajTM software...

Fabrication and Capacitive (C-V) Characteristics of Conjugated Polymer Composite (P-PolyanilineN-Wo3) Heterojunction

Abstract A nanocrystalline and porous p-Polyaniline/n-WO3 dissimilar heterojunction at ambient temperature is reported. The high-quality and well-reproducible conjugated polymer composite films have been fabricated by oxidative polymerization of anilinium ion on predeposited WO3 thin film by chemical bath deposition (CBD). X-ray diffraction analysis of the deposited WO3 films revealed that as-deposited film was amorphous; however, an amorphous-to-crystalline phase transition was observed by ...

Measurements of Radiation Doses of Natural Radioactive Material in Oil fields at West Kourdofan

Abstract Scale, sludge and sand samples were collected and analysed using thallium activated sodium iodide NaI(Tl) spectrometer to determine type, activity concentration, absorbed dose rate and annual effective dose of naturally occurring radioactive material (NORM) of samples collected from oil fields at West Kourdofan state. Scale radionuclides was found to be, 238U, 232Th and 40K at concentrations ranged from (4106.9 - 358.05) Bq/Kg, (2736.7 - 375.88) Bq/Kg and (9294 - 16.07) Bq/Kg respec...

Effect of Magnetic Field on the Thermal Conductivity of Single Crystal

ABSTRACT This research investigated the effect of magnetic field on the thermal conductivity of high temperature type II superconductors. The result suggested that the thermal conductivity of high temperature type II superconductor YBa2Cu3O7- decreases as the applied magnetic field increases at a given temperature. We also found out that the superconducting energy gap of YBa2Cu3O7- decreases in response to increasing temperature and applied magnetic field. At a critical temperature of ...

Geophysical Investigation of Abakaliki Area using Aeromagnetic Method

ABSTRACT  Aeromagnetic data over Abakaliki area of the lower Benue trough of Nigeria was interpreted qualitatively and quantitatively using Oasis montaj software (version: 6.4.2 H.J).The interpretation unveiled basic intrusive bodies like dyke, lacolyte and batholyte in the study area. It also showed fault zone which trends North East to south western (NE-SW) part of the study area. Quantitative interpretation of the area was carried out by source parameter imaging and forward and inverse mo...

Improving Soba Solar Contact Cover for Fixed PV Modules by Using Acrylic Sheets

Abstract  In this research specifications of acrylic plate had been examined to evaluate its reliability to be used as alternative for the glass cover in the SobaSolar fixed PV modules. The maximum power of a fixed PV module composed of × . solar cell panel in outdoor test was found to be about: 3.42 Watts, that is when acrylic cover was attached to the module replacing the normal glass. This results showed that no significant change in the maximum power was made by using acrylic glass cove...
