ABSTRACT

This paper discussed technological innovation for the enhancement of performance of tertiary institutions in Rivers State. The paper examined technological innovation in the aspects of asynchronous technology, asynchronous technology and learning content.  The paper anchored its theory on diffusion theory. The paper suggested that higher education practitioners should make adequate Information and Communication Technology (ICT) facilities in their lecture halls as well as other learning facilities in the campus. Parents should also make available cheap smart-phones and other related facilities.

ABSTRACT

The genuine (expansion changed) gross domestic product of Nigeria is concentrated here by Principal Component Method. An acknowledgment of the arrangement from the main quarter of 2018 to the second from last quarter of 2019 is analyzed using Minitab 12 programming. Both the correlation matrix and the covariance matrix are used. Eigen analysis of both matrices suggest that the first three principal components are enough to explain variation in the data set. The correlation principal components involved all the items. The covariance principal components did not involve all the items which is a deficiency. For instance, animals, ranger service, fishing, strong minerals, development, transport, utilities, convenience and food administrations, account and protection, proficient logical and specialized administrations, regulatory and support administrations and business administrations, policy management, human wellbeing and social administrations and expressions, amusement and entertainment are not included. This makes the technique substandard.

ABSTRACT

The goal of this work is to obtain tunneling probability of a gamma particle. The application of Schrӧdinger’s equation in barrier penetration has been applied to gamma particle decay for light, medium and heavy nuclei. Gamma particle tunneling probability has been calculated analytically. Decay probability computed for each gamma particle emitting nucleus shows interesting variations. Log plot of calculated Decay constant plotted against atomic number (Z), mass number (A) and Energy for gamma particle emitting nucleus shows the variations interesting.   Half-life which is a function of decay probability plotted against gamma particle energy or against atomic number of gamma particle emitting nucleus shows the variations of decay probabilities. Log plot of Calculated Half-life plotted against atomic number (Z), mass number (A) and Energy for gamma particle emitting nucleus shows interesting variations of decay probabilities. Calculated half-lives compared with experimental half-lives for each gamma particle emitting nucleus shows results which are in good agreement.

Key word: Emission, Gamma, Schrӧdinger’s equation, Decay constant and Half-life.

ABSTRACT

Numerous waste materials are generated from manufacturing processes, service industries and municipal solid wastes. The increasing awareness about the environment has tremendously contributed to the concerns related with disposal of the generated wastes. Solid waste management is one of the major environmental concerns in the world. With the scarcity of space for land filling and due to its ever-increasing cost, waste utilization has become an attractive alternative to disposal. Today there are still many issues about landfill capacity problem. Plastics are one of the most widely used materials that change the human life for more than six decades ago. Plastic waste has a slow degradation rate. In this study Polyethylene Terephthalete (PET) is used as fibre to investigate the compressive and flexural behavior of concrete. To address this issue the fibers from used plastics were added in various percentages in the concrete. The aim of this research is to determine the strength of concrete produced using shredded plastic bottle fibre as reinforcement. The compressive and tensile strengths of various concrete specimens were tested to determine how the incorporation of recycled plastic as a replacement of coarse aggregate would affect the development of strength in the mixes. A series of five concrete mixes were compared at replacement increments of 0%, 5%, 10%, 15%, and 20%. All stages of plastic replacement showed a noticeable decrease in compressive strength. The test results were compared and the relationships between the observed and predicted strengths were given. It was observed that both the compressive and flexural strengths decreased with each increase in percentage addition of plastic. At 5% addition of PET there was a 20% decrease in compressive strength and a 40% decrease in flexural strength of concrete respectively. Thus, it was recommended that shredded polyethylene terephthalate can be used for non-structural elements.
