In the last century, a small minority of physicists considered a hypothetical binary logarithmic connection between the large and the small constants of physics, which also implies a base-2 power law (Fürth, 1929; Eddington, 1938; Teller, 1948; Salam, 1970; Bastin, 1971; Sirag, 1980, 1983; Sanchez, Kotov and Bizouard, 2009, 2011, 2012; Kritov, 2013). This paper brings to attention a plausible triple electro-gravito-informational significance of the fine structure constant, with its implications in a plausible four fields unification pattern at Planck scales: this triple significance is based on the existence of a unifying global scaling factor of nature which appears in a hypothetical fine tuning of all the non-zero rest masses of the all the elementary particles in the Standard Model. Furthermore, this paper also proposes the dimensional relativity hypothesis (DRH) stating that the 3D appearance of space (or the 4D nature of spacetime) may be actually explained by the relative magnitude of the photon (angular) quantum momentum (and the hypothetical graviton quantum momentum respectively) and this global scaling factor (GSF): DRH also includes a generalized electrograviton model (EGM) for any hypothetical graviton. This paper also proposes a set of strong (and very strong) gravity constants and a gravitational field varying with the energy (and length) scale, all with potential importance in the unification of the four fundamental fields. Each of these hypotheses is a potential update for the Standard Model of particle physics.

Aim: The objectives of this study was to measure the activity concentration of natural radionuclides in different drinking water sources in order to access the associated radiological health risk due to ingestion of such water.

Study Design: The design of this study is purely experimental.

Place and Duration: This study was carried out on drinking water sources around Uburu and Okposi salt lakes areas of Ebony state between April and September, 2016.

Methodology: Sachet waters, borehole water, stream and river waters were collected and chemically treated by adding few drops of nitric acid to each of the samples and then pre-concentrated and kept in a marinelli container for four weeks. The activity concentration of 226Ra, 232Th and 40K in all the water samples was measured using the High- Purity Germanium detector. Results: The specific activity concentration of 226Ra, 232Th and 40K ranged from BDL to 3.66± 0.78 Bql-1, BDL to 7.56 ± 0.0.59 Bql-1 and BDL to 23.31 ± 1.65 Bql-1 respectively in sachet water. The activity concentration of 226Ra, 232Th and 40K in borehole water ranges from BDL to 5.65±1.25, 0.45±0.09 to 13.00±0.97 and BDL to 26.45±1.83 Bql-1 respectively. Furthermore the activity concentration of 226Ra, 232Th and 40K in stream water ranges from BDL to 2.88±1.32 Bql-1, BDL to 8.93±0.66 Bql-1 and BDL to 33.32±2.18 Bql-1 respectively, while that for river water ranges from 0.03±0.01 to 4.48±1.13 Bql-1, 0.55±0.10 to 8.60±0.65Bql-1 and BDL to 13.85 ±0.98 Bql-1 respectively. The mean values of annual effective dose obtained for infants, children and adults are within the ICRP and WHO recommended reference values. The life-long cancer risk and hereditary effects due to ingestion of radionuclides by adults show that 16 out of 100,000 may suffer some form of cancer fatality and 9 out of 100,000 may suffer some hereditary effects. Statistical analysis of the data revealed a positively skewed and platokurtic distribution of radionuclides in all the drinking water sources.

Conclusion: All the radiological health risk parameters obtained were within their safe values. Therefore, all the sampled drinking water are radiologically safe for domestic use but infant should not be given any of the studied drinking water since the annual total effective dose for infant exceeded the safe value.

The solutions of the klein-gordon equation with Manning-Rosen plus Yukawa potential (MRYP) has been presented using the Pekeris-like approximation of the coulomb term and parametric Nikiforov-Uvarov (NU) method. The bound state energy eigenvalues and the corresponding un-normalized eigen functions were obtained in terms of Jacobi polynomials. So also, Yukawa, Manning-Rosen and coulomb potentials have been recovered from the mixed potentials and their eigen values obtained.

AIM: This research project was undertaken to compare the optical and physical properties of aerosols at the 0.440 μm, 0.675 μm, 0.870 μm and 1.020 μm spectral wavelengths between desert and monsoon-influenced regions. In this project, Zinder, one of the popular cities in the Republic of Niger and Beijing, the capital city of China were chosen to represent desert and monsoon- influenced regions respectively.

Place and Duration of Study: Four years of Aerosol Optical Depth (AOD) data were extracted from level 2.0, the quality-assured almucantar version products of AERONET data, at both Beijing-CAMS (39.933°N, 116.317°E) and Zinder Airport (13.775°N, 8.984°E) between 2012 and 2015.

Methodology: In this research project, physical and optical properties of aerosols were determined using Angstrom equations. Angstrom exponent, curvature, turbidity coefficient and spectral variation of the aerosols in Zinder Airport and Beijing-CAMS were calculated and the results were then compared. Both the physical and optical properties of the aerosols were determined from the calculated values.

Results: The results obtained indicated that there were dominant coarse-mode aerosol particles in Zinder city, while fine-mode aerosol particles were found in Beijing. The results also showed that the overall Aerosol Optical Depth (AOD) in Zinder is higher than that of Beijing, but the atmosphere of Beijing was hazier than that of Zinder.

Conclusion: The prevalence of coarse-mode particle sizes in Zinder was due to desert dust particles in the region, while the prevalence of fine-mode particles in Beijing was due to anthropogenic aerosol particle generation in the region, which may result from heavy industrialization in China. The higher aerosol loading in Zinder is responsible for absorbing light coming from the sun which, in turn, makes the atmosphere clear, while the lower aerosol loading in Beijing is responsible for scattering light coming from the sun, thereby obstructing the atmospheric visibility in the region.

Electrical resistivity tomography (ERT) technique has been used in this research to evaluate the contamination zones at a dumpsite in Benin City. Three electrical resistivity profiles were established for the purpose of the research. The pseudosection maps and the apparent resistivity values helped in identifying the nature and depth of the conductive sources in the study area. The field survey was carried out using Dipole-dipole array with a spread of 164 m at Ikpoba Okhia local government approved dumpsite in Benin City, Edo State. The ERT method revealed highly conductive zones of less than 20 Ωm of leachate to the depth of 39.4 m. The area shows subsurface resistivity distribution at the Eastern part of the study area trending East with prominence at the center and distributed North - East which has been interpreted as fractured or migration zones of leachate. The depth estimate revealed the apparent depth to the causative body from the surface with depth range from 0.34 m to 39.4 m which agrees with other literatures. The study has revealed that the area is generally highly conductive due to the presences of toxic elements while the fractured zones are prospective locations for infiltration of contaminant plums (leachate).
