This research work was carried to examine the rate of production of biogas through anaerobic digestion of fresh Cow rumen obtained from slaughter house in Woji, Trans-Amadi, Port Harcourt. The Kinetics of the biogas produced upon the influence of biodegradation was studied using kinetic model linear, power, growth rate decay, non-elementary rate models to establish the model that best predicts the amount of biogas obtained from the experimental obtained parameters. The total solid, volatile solid, ash content and pH was evaluated upon the influence of the biomass. Also, the temperature and pressure build-up during the anaerobic digestion process were recorded weekly. The results of the analysis showed that is, volatile solid, ash content were 0.924g/g, 0.734g/g and 0.1414g/g, while the PH value before and after the analysis were 7.45 and 7.26 as well as fluctuation in temperature between 300C and 34.50C was observed.
There are various control methodologies for direct current motors with each method possessing its attendant peculiarity
The move towards a de-carbonised world, driven partly by climate science and partly by the business opportunities it offers, will need the promotion of environmentally friendly alternatives
China has a vast territory and a large population, so rail transit has always been an important direction of China's development. With the continuous development of rail transit in China, higher requirements put forward for the efficiency, safety and stability of train operation
The offshore industry has seen the introduction of a new breed of jack-up designs, capable of operating in deep water and harsh environments
Robot manipulator route planning can be defined as the process of simplifying any motor task into a single movement, while satisfying the movement restriction and optimizing the cost function
This paper generally deals with the differences of results using limit equilibrium method and finite element methods in case of soil slope stability analysis to develop correlations for the value of factor of safety.

The problem of calculating the dynamic stress-strain state of viscoelastic rectangular isotropic plates on a deformed base, including those lying freely on the ground medium under the influence of vibration loads, is solved
The paper presents an experimental investigation out to evaluate the mechanical properties of concrete mixtures in which fine aggregate (sand) was replaced with Copper Slag (CS)
The research work deals with an experimental investigation of the properties of steel fibre reinforced concrete (SFRC). It studied thirteen samples of SFRC mixes of M30 concrete of varying dosage of 3D and 5D steel fibres; ranging from 25kg/m3 to 45 kg/m3.
Investigation was conducted in some communities of Cross Rivers State to experimentally examine the effect of soil characteristics on metal corrosion in different soil environment of clay, swampy and sandy.
The bumper beam is an important member which is integrated in front portion and the rear portion of the vehicle. The purpose of the bumper is to absorb the impact energy in the case of crash and guard the central operational components
