ABSTRACT: Background: Concentration of greenhouse gases in the atmosphere has increased rapidly due to anthtopogenic activities resulting in significant increase in temperature of the Earth causing global warming. Assessing the greenhouse émissions is an important step towards making quantifiable émission reduction. This study focuses on estimating the concentration of greenhouse gases émission in Michael Okpara University of Agriculture (MOUAU), umudike. Materials and Methods: In this comparative study, the concentration levels of Carbon monoxide CO, Sulphur IV Oxide SO2 and Nitrogen IV Oxide NO2 were measured in using Crowncon gasman monitor model CE89/336/EEC (Handheld) in Seven different different locations scattered spread across theUniversity in two consecutive days in September, 2015.....

ABSTRACT: Background: The moisture content of the atmosphere can be expressed in various units. These units can be used in the prediction of various events in the atmospheric boundary layers. The inadequacies in the measurement of atmospheric parameters, limits in-depth and valuable research from being carried out. In a bid to cushion these effects on research, various methodologies have been employed in addition to making suitable assumptions that enable the use of available measured parametric data to generate data and results for which unmeasured parameters would have served same purpose. The measurement of wet bulb temperature and dry bulb temperature from meteorological stations would rather have made this study parochial, save for various methodologies used in the calculation of dew-point temperature. Large dependence of diurnal variability of moisture parameters with dew point temperature makes it imperative for its calculation and development of an alternative but suitable technique in its estimation......

ABSTRACT: Vibrating Higgs Bosons define space-time. Higgs Bosons define universe. They are the primitive source of mass and dark energy. The visible portion of universe is the manifestation of dark energy. Without the support of dark energy, visible world cannot exist. In this article it has been demonstrated that all events e.g. formation of galaxy, formation of subatomic particles like electron, positron, neutrino, formation of atom, different states of matter, surface tension, conductor and insulator, thermocouple, Positive energy and negative energy, Laws of thermodynamics, Super conductivity, Super fluidity and black hole are the result of space-time dynamics caused by Higgs Bosons. No fresh mathematical model......

ABSTRACT: Accelerator is a machine in which particles are accelerated according to the desire of the Scientists. A Collider is taken to mean a Particle accelerator in which two beams are travelling in opposite directions and collide with each other. Many and most important discoveries in the last 50 years are due to Collider Physics. A Collider has a lot of advantages over the fixed target accelerator....

ABSTRACT: Plasma assisted combustion (PAC) is a newly growing field and a promising technology which has attracted many researchers to explore the effect of PAC on combustion control, combustion enhancement, flame stabilization and so on. This paper presents the history of PAC, its properties, types, effects and applications. In space propulsion, plasma thrusters are challenging the monopoly of chemical thrusters. Helicons is the highly efficient source of plasma and being used in plasma propulsion applications. In this paper we discussed why non-equilibrium plasma is preferred over equilibrium plasma. PAC is used for ignition enhancement in SCRamjet, IC and SI engines and PDE along with its several applications in gas turbine engines..

ABSTRACT: The aim of the study is to analyze the possibility of reducing the toxicity of air, in which viruses (including SARS-CoV-2) and other pollutants are dispersed, using acoustic methods. Under the influence of an acoustic wave, particles in the air undergo a certain movement, a kind of displacement, called drift. This effect is activated by the mechanism associated to the nonlinear propagation of acoustic waves. Drift forces depend on the position of the particles, their size and the parameters of the acoustic wave and the medium they spread in. In the process of the impact of acoustic waves, the average size of suspended particles increases. The agglomeration may occur between small particles creating larger particles. The agglomeration can occur due to the acoustic and orthokinetic mechanisms......

ABSTRACT: In the absence of a reference corpus on air pollution profiles at Nigeria's capital city of Abuja, this study was designed to be a pilot in the hope that its structure would form the basis for further suchlike air pollution studies such that a reference corpus may be created. The part of Abuja chosen for this pilot study was the heavily built-up Federal Capital City (FCC), the "heart" of the capital. Seventy-six major traffic stalling points were identified in the FCC: a traffic stalling point (TSP) is defined to be a road junction or node where all practical motor-mobiles (that is, cars, trucks, motor-cycles, motorized rickshaws, etc.) necessarily decelerate upon approaching the junction, for safety.....
