ABSTRACT: The Guzabure and Gudumbali regions, within the Chad Basin, Northeastern Nigeria have been interpreted qualitatively and quantitatively using the aeromagnetic data of the area. Euler deconvolution technique and source parameter imaging method were employed in the analysis of the work. Application of minimum curvature in gridding the total magnetic field intensity was done using the Oasis Montaj 6.4.2 software. First order polynomial fitting was applied in Regional - residual separation. The residual magnetic intensity map shows the existence of intrusive bodies in the study area. From the aeromagnetic result, the depth to basement estimated using the Euler depth technique range from 721.1m..........

ABSTRACT: The mineral composition of rocks was investigated using the mass spectrometer with inductively coupled plasma. According to these data, the composition of rocks is calculated by the proportion of these minerals in the rock and on the basis of them are constructed lithological-petrographic profile sections with the selection of zones of change of rocks. The data obtained in the aggregate allowed us to outline the zone of migration of fluids from oil and gas deposits, which provides additional information when assessing the prospect for prospecting areas. The integrated use of these methods made it possible to confidently predict oil and gas fields.

ABSTRACT: This work investigates the impact of radio refractivity over Enugu, South Eastern Nigeria using atmospheric parameters of temperature, pressure and relative humidity collected from August 2017 to July 2018 respectively, we downloaded our data from Automated Weather Station and Signal Strength Meter in the Department of Industrial Physics Enugu State University of Science and Technology using Davis weather station vantage pro 2 positioned close to the ground surface. The data were logged at 30 minutes' interval continuously for each day during the period. Hourly, daily and monthly averages of radio refractivity during dry and wet seasons were calculated from the data obtained. The result indicated that the radio refractivity during the wet season is greater than the dry season.......

ABSTRACT: Near-Earth Objects (NEOs) are small solar system bodies (approximately 10 – 1500 m in diameter) with some having orbits that cross Earth's orbit. They are considered to be the remnants of the early solar system. Potentially hazardous asteroids (PHAs) is reserved for those objects with absolute magnitudes H ≤ 22 and diameter > 140 m. In principle, PHAs could possibly impact the Earth within the next century, producing major damage. We present a comparative study potentially hazardous asteroids (PHAs) providing some insights on the nature, origin, evolution, physical properties, chemical composition and potential hazards of these objects. We obtained our data from National Aeronautics and Space Administration (NASA) catalogue using descriptive statistics in our analysis, for 1811 potentially hazardous asteroids spanning from 1990 to 2018 comprising 1528 Apollos, 163 Atens, 114 Amors and 6Atiras. Statistical analysis reveals that Apollos accounts for about 84.3% of the confirmed PHAs while Amors, Atens and Atiras accounts for 6.3%, 9%, 0.33% respectively of the known PHAs

ABSTRACT: In this paper an attempt has been made to review microwave dielectric behaviour of soil in Chhattisgarh. Soils are complex mixture of minerals , water, air, organic matter, and countless organisms that are the decaying remains of once-living things. The properties of soil such as physical properties, chemical properties, geographic properties are really important in production of agriculture. To perform dielectric constant microwave test bench generally used. The parameter of soil affects the production of grains. It has been observed that the dielectric constants are strongly dependent on moisture content. Dielectric constant decreases with increasing percentage of sand. Dielectric constant increases with increasing percentage of silt. Dielectric constant increases slowly with increasing conc. Fertilized soil . There are a lot of parameters but moisture content is the very important. In the laboratory the properties of soil are utilized for study which is very useful in agriculture..

ABSTRACT: According to Yangton and Yington Theory, for an observation on earth, in addition to have larger length and time, an object and event happen on a massive star (black hole) with large gravitational field has smaller velocity and acceleration comparing to that of the corresponding identical object and event happen on earth with less gravitational field. This result agrees very well with general relativity..

ABSTRACT: The word chaos is the science of surprises of the nonlinear and unpredictable. It teaches us to expect the unexpected. In this chaos theory using mathematical equations we study the behaviour of dynamical system that are highly sensitive to initial condition. To study non linear behaviour of quantum H.H. Oscillator, equation of continuity and Euler equation can be used. The evolution of shanon entropy, density and amplitude correlations and kinetic energy exhibit non linear oscillations.Charge density and velocity potential can be used to study of nonlinear features.

ABSTRACT: In this paper we start from basic postulates of quantum mechanics such as that the volume integral of the probability is conserved. The consequence of this is that the total time derivatives of the probability, the value of the radius and the solid angle are zero. Next we conclude that there is quantization of magnetic flux which for big values of the magnetic induction is not observed in the macro world.

ABSTRACT: Author: Le Thi Thuy Hang Abstract: The biomass pyrolysis has been a way to generate a bio-char, including rice husk. In Vietnam, the rice husk has covered more than 10% of total biomass, and been a potential alternative energy source in the context of fossil fuel sources in running out. Our study of rice husk pyrolysis has been acted in two separate reactors, a muffle furnace and a macro-TG, under nitrogen surroundings. The peak temperatures were at 873 K and 1173 K, and the heating rates were at 293 K.min-1 and 2073 K.min-1. The achieved results have provided more data and technical analysis of the feasibility of bio-char generation from rice husk in Vietnam. The perfect conditions to get the best bio-char have found at peak temperature of 873 K and heating rate of 293 K.min-1 with Te Do rice husk from Red River Delta.

ABSTRACT: An ordinary coronal mass ejection might have any or all of three particular highlights: a pit of low electron thickness, a thick center (the noticeable quality, which shows up on coronagraph pictures as a splendid region installed in this depression), and a brilliant driving edge. Most ejections start from dynamic regions on the Sun's surface, for example, groupings of sunspots related with continuous flares. These regions have shut magnetic field lines, in which the magnetic field strength is adequately huge to contain the plasma. These field lines should be broken or debilitated for the ejection to escape from the Sun. Nonetheless, CMEs may likewise be started in calm surface regions, albeit much of the time the tranquil region was as of late dynamic. During solar minimum, CMEs structure essentially in the coronal decoration belt close to the solar magnetic equator. During solar maximum, they begin from dynamic regions whose latitudinal appropriation is more homogeneous.
