Quantum Information Technology Based on Magnetic Excitation of Single Spin Dynamics

The single spin dynamics of a single electron was investigated theoretically by exciting the single electron magnetically. Different possibilities e.g quantum mechanical noise, inelastic collision emerged. To attain high performance of the quantum information technology, a low magnetization favoured the excitation process

Air quality investigation over Moundou Chad

The air quality over Moundou-Chad was examined using satellite dataset. Fifteen years aerosol optical depth (AOD) was obtained from the Multi-angle Imaging Spectro- Radiometer (MISR). The AOD dataset is statisticaly stable for further prediction. The highest AOD mean was observed in 2008. The standard deviation, average deviation and coefficient of variation all agrees that the AOD dataset is reliable. It is shown that the aerosol loading over Moundou is high and the size of the aerosol is very tiny to deposit in the human lungs

ANALYSIS OF THE HIGH TEMPERATURE SUPERCONDUCTING MAGNETIC PENETRATION DEPTH USING THE BLOCH NMR EQUATIONS

The Bloch-NMR diagnostic tool has shown good efficiency not only analyzing biological and physiological properties of living tissues. The Bloch-NMR has been used in this research work to analyze the penetration depths of superconducting material and thin film. From the two well known London penetration depths, various relationships between the penetration depth and other superconducting quantities were derived (which are theoretically and experimentally valid). The major objective is to explore new ways penetration depths can be measured. A new superconducting quantity (penetration velocity) was discussed - whose relationship with other superconducting quantities were worked out for further researc

Parametric Investigation of Soil Susceptibility to Compaction Using Temperature Deviation Curves

Soil compaction can be explained using basic properties of soil. Cohesive soil sample were collected from five major region of the main site of investigation. Unlike other method of analyzing soil compaction, temperature deviation curves were used as the determinant for testing for compaction. It was discovered also that the temperature deviation curves can be used to find the annual amplitude of the surface soil temperatures. Soils in Abuja displayed some degree of compaction except for Gwagwalada that showed negligible compaction. Garki location produced the highest compaction at 14cm depth. The highest annual amplitude of the surface soil temperatures was noticed in Kuje and the lowest in Bwari

CRYSTALLINE GRAIN SIZE EFFECTS ON THE CONDUCTIVITY OF THE DOPED TIN DIOXIDE (SnO2) WITH ZINC (Zn)

Nigeria Spray pyrolysis technique was used for the fabrication of the sample. A series of SnO2 and Zn doped SnO2 (Zn. SnO2) have been deposited on the glass slide with different doping concentration values of 1 wt.% , 2 wt.% ,3 wt.% and 4 wt.% Zn on SnO2. The average grain size of the Zn doped SnO2, compare to the average grain size of SnO2 film is clearly increasing upon increase in doping concentration. However, grain boundary theories were obeyed except for the 4 wt.% Zn on SnO2 which showed a high level of doping incompatibility. At 1 wt.% Zn on SnO2 exhibited the characteristics of a homogenous and stable p-type semiconductor. At 3 wt.% Zn on SnO2, the direction change in the orientation of two adjacent grains was shown to localize at a site equidistant to the grains

Parametric Analysis of Ground Temperature Profile in Bwari-North Central Nigeria

Predicting future climatic changes is a vital key towards positioning both private and governmental budgeting. This study was on the validity of predicting natural disasters using data from ground temperature. The Bwari region of Abuja-Nigeria was the research site and the research duration was five years. The net earth radiation was discovered to have increased and has been unable to be abated by natural forces. 2013 might experience an increased solar radiation upon the earth, though, there may be a reduced flooding and a heavier flooding in 2014 or 201

Outdoor Air Pollution in Kumbo Cameroun

In this paper, the air quality of Kumbo-Cameroon was investigated. Aerosol optical depth (AOD) dataset for fourteen years was obtained from the Multi-angle Imaging Spectro-Radiometer (MISR). The raw dataset was processed and treated. The aerosol loading over the research location was obtained from the AOD datasets. It was observed that the main pollution is from anthropogenic emission and Sahara dust. The current aerosol loading over Kumbo is high and it is gradually reducing by 1.81%, though not significantly. The data presented is essential for ground measurement over the research area

Spectral filtering experimentation on photovoltaic cells using novel bio-filter made from copper coated hibiscus-ethanol extract

The challenges facing solar power grid system in Africa is huge. Most salient of these challenges is the inefficiency of the photovoltaic (PV) panel to sustain its output for more than a year. Certainly, the harsh weather condition in the region can be said to be one of the reasons for the shortcoming that was earlier highlighted. In this research, bio-filters were suggested to filter the harmful radiation hitting the PV panel. The bio-filter is made up of copper coated hibiscus extract. The hibiscus extract was done using ethanol solution. It was observed that the bio-filter was able to filter the some of the harmful radiation as expected. The quantity of the harmful solar radiation was not estimated because of the limitations of the equipment used for the research. It is recommended that this highlighted shortcoming of the research should be taken further to ascertain i.e. in percentage the harmful radiation that has been filtered by the bio-filter during the experiment

The physics of the sheath effects in monopole plasma antenna or helix plasma antenna

The magnetic field in the sheath of monopole plasma antenna or the helix antennas has been found to have a negative impact on its general functionality. The vertical and horizontal signals at predetermined angles had been compromised by the sheath effect. It was observed that this phenomenon is almost unnoticed because magnetization has the highest magnitude when the device is switch on/off. In microscopic scale (monopole plasma antenna), the sheath effect is due to femto spin demagnetization of particulates. However, in macroscopic scale (helix antenna), the sheath effect is due to signal impairment
