Effect of Automotive Gas Oil (AGO) on Geotechnical Properties of Lateritic Soil

Environmental pollution from petroleum and petrochemical products has been recognized as one of the most serious problems associated with accidental spills on a large scale. This study was carried out to investigate the effect of automotive gas oil (ago) on geotechnical properties of lateritic soil. Test carried out included Optimum Moisture Content, Maximum Dry Density, Sieve Analysis, Liquid Limits, Plastic Limits, Plasticity Index, Specific Gravity and Unconfined Compressive Test. Certain percentages of AGO (0 %, 4 %, 8 %, 12 %, 16 %) were mixed with the lateritic soil sample. Based on the results obtained, Optimum Moisture, Maximum Dry Density, specific gravity and unconfined compressive test decreased as the percentage of automotive gas oil (AGO) increased, while Atterberg limits and Sieve analysis increased as the percentage of automotive gas oil (AGO) increased. Addition of AGO to the soil led to the reduction of porosity and permeability resulting from the entrapment of the AGO within the pore spaces of the soil.

Energy – Momentum of the Armenian Special Relativity Theory

In this paper, the energy and momentum of the Armenians Special Relativity Theory (ASRT) and Special Relativity Theory (SRT) are obtained and their comparison is also carried out. SRT through the Muhelson-Morlay experiment proved that aether does not exist in space, but ASRT reincarnates the aether as a universal reference medium. The mathematical existence of aether has already been proven. In his work, by comparing energy and momentum of both SRT and ASRT, the results obtained indicate that difference is  in the time-space or subatomic aether medium which is represented by space coefficient  and geometrical space . The theory brings together followers of absolute aether theory, relativistic aether theory and the dark matter theory. The energy and momentum in SRT can be deduced from ASRT by substituting  and . This implies that, SRT is a limiting case of ASRT. Keywords: Relativistic theory, Rest Particle, Dark Energy, Armenian Theor

Interactions of Axion Photons in Magnetised Media

We have compared between the standard model and generational model of particle physics. By means of a special Lagrangian function we consider the interaction of photon axions in both magnetic field and magnetic medium. We also present a polynomial in powers of the external magnetic field with even and odd powers .... DOI: 10.7176/APTA/83-01 Publication date: February 29th 202

Non-Relativistics Treatment of Schrodinger Particle under Modified Inversly Quadratic Hellmann Potential Model Via Parametric N-U Method

The non-relativistics study of particles under the modified inversely quadratic Hellmann potential has been studied. The energy eigenvalues and the corresponding wavefunction expressed in terms of the Jacobi polynomial are obtained using the parametric NU method. In obtaining the solutions for this system, we have used an approximation scheme to evaluate the centrifugal term (potential barrier). To test the accuracy of our result, we compared the approximation scheme with the centrifugal term and the result shows that there is an agreement between the centrifugal term and the approximation scheme for a very small screening parameter; showing that our potential is a short range potential. The results obtain from this work, would have many application in inner shield ionization problem, Electron core, Solid state Physics, Alkali-Hydride molecules. Three special cases of this potential have also been discussed

Approximate Solutions of the Non-Relativistic Schrödinger Equation with Inversely Quadratic Yukawa plus Mobius Square Potential via Parametric Nikiforov-Uvarov Method

We study Schrödinger equation for inversely quadratic Yukawa plus Mobius square potential using the generalized parametric form of Nikiforov-Uvarov method. We obtain energy eigenvalues and the corresponding normalized wave function expressed in terms of the hypergeometric functions. Three special cases of this potential have been discussed. Numerical values of the energy eigenvalues are also computed for various states. Keywords: Approximate solutions, Schrödinger equation, Nikiforov-Uvarov method, inversely quadratic Yukawa potential, Mobius square potentia

Jatropha tanjorensis Euphorbiaceae ameliorates aspirin-induced hepatotoxicity and maintain electrolytes balance in albino Wistar rats

Background: A great number of modern medicines derived from plants are considered as important sources of medicinal agents to treat different diseases. J. tanjorensis belongs to the family Euphorbiaceae, which is known for various medicinal uses. Purpose: The hepatoprotective effect of ethanolic extract of J. tanjorensis Euphorbiaceae and maintenance of electrolytes balance in aspirin-induced hepatotoxic condition in Wistar rats was studied. Methods: 20 Wistar rats of both sexes weighing between (180–200 g) were divided into 4 groups of 5 rats each.  normal rat (group 1); J. tanjorensis Euphorbiaceae (200 mg/kg group 2); aspirin (250 mg/kg group 3); aspirin (250 mg/kg) + J. tanjorensis Euphorbiaceae (200 mg/kg group 4). Serum levels of the enzymes aspartate transaminase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and electrolytes (Na+, K+, Cl−, and HCO3−) was assessed at the end of treatment which lasted twelve (12) weeks. Results: When compared to control, J. tanjorensis Euphorbiaceae - treated, and aspirin+ J. tanjorensis Euphorbiaceae - treated groups, blood electrolyte results in aspirin-treated group indicated a significant decrease (p<0.05) in sodium, potassium, chloride, and bicarbonate levels, respectively. Treatment with J. tanjorensis Euphorbiaceae leaves extract resulted in normal levels of serum electrolytes (Na+, Cl−, and HCO3−). When compared to J. tanjorensis Euphorbiaceae, control, and aspirin + J. tanjorensis Euphorbiaceae -treated groups, the serum liver enzyme level was significantly (p<0.05) increased in the aspirin-treated group. When compared to the aspirin treated group, serum liver enzymes level in the J. tanjorensis Euphorbiaceae treated group was significantly lower (p<0.05). The relative liver weight and mean body weight in the aspirin-treated group was significantly lower (p<0.05) compared to J. tanjorensis Euphorbiaceae, control, and aspirin + J. tanjorensis Euphorbiaceae - treated groups respectively. Conclusion: The results suggest ethanolic leaves extract of J. tanjorensis Euphorbiaceae offered hepato-protective effect in aspirin-induced hepatotoxic condition on tissues, ameliorated both hyponatriemia and hyperkalemia effects,  and maintained normal electrolytes concentration in animal models
