Design and Construction of an Automatic Power Changeover Switch

Abstract Power failure or outage in general does not promote development to public and private sector. The investors do not feel secure to come into a country with constant or frequent power failure. These limit the development of industries. In addition there are processes that cannot be interrupted because of their importance, for instance surgery operation in hospitals, transfer of money between banks and lots more. This paper presents the design and construction of an automatic power chan...

Measures for Mitigating the Effects of Climate Change on Crop Production in Nigeria

This paper examined the causes, effects and measures for mitigating climate change to ensure adequate supply of food through crop production to address the food insecurity which has occupied a central focus of the Nigerian economy. Unfortunately, crop production is fraught with many ecological challenges including climate change. This climate change which occurs as a result of the buildup of Green House Gases (GHGs) occasioned by industrialization, technological modeling and agriculture, exer...

Anhydrous Monoalkylguanidines in Aprotic and Nonpolar Solvents: Models for Deprotonated Arginine Side Chains in Membrane Environments

ABSTRACT: In this study, the synthesis of crystalline dodecylguanidine free base and its spectroscopic characterization in nonpolar environments are described. IR as well as 1 H and 15N NMR spectra of the free base dissolved in aprotic solvents are substantially different from the previously reported spectra of arginine, or other monoalkylguanidinium compounds, at high hydroxide concentrations. The current results provide improved modelling for the spectroscopic signals that would be expecte...

DESIGN AND CONSTRUCTION OF AN AUTOMATIC CHANGEOVER SWITCH

ABSTRACT The main aim of any electric power supply in the world is to provide uninterrupted power supply at all times to all its consumers. Although, in developing countries, the electric power generated to meet the demands of the growing consumers of electricity is insufficient, hence power instability and outage. Power instability or outage in general does not promote development in the public and private sector. The investors do not feel secure to come into a country with constant or frequ...

THE IMPACT OF THE TOTAL QUALITY MANAGEMENT (TQM) ON PRODUCTIVITY (A CASE STUDY OF DIAMOND BANK, LTD OWERRI)

ABSTRACT As regards to this topic, TOTAL QUALITY MANAGEMENT (TQM) it goes on reviewing the better ways of improving productivity, product quality, and deliver services. Organizations that adopt the concept of total quality management as culture in the direction of altering the behaviour of managers and employees have become low cost, high quality and high productive in the supply of goods and services in order to honour and support the contributions of all organizational members. This study ...

Some mew and generalized families of probability distributions with applications

Abstract: Some new generalized distributions called the new Gamma Lindley-Log-logistic (GLLLoG) distribution, new Weibull Generalised-G (NWG-G) family of distributions and the Exponentiated Half-Logistic Odd Lindley-G family of distributions are proposed and presented. These distributions contain several distributions such as Half-Logistic, Odd Lindley, Lindley, Log-Logistic, new-Rayleigh generalized-G, new exponential generalized-G, new Rayleigh-G and the new-Weibull-G family of distributio...

THE ROLE OF CENTRAL BANK IN STABLISHING NIGERIA ECONOMY (A CRITICAL REVIEW)

ABSTRACT    Central banks are general known to be concerned with the maintenance of monetary stability.  This task involves the regulation of money in circulation  consistent with the absorphic capacity of the economy axiomatically, excessive growth in money supply rates to high rates of spending on domestic or foreign goods given that domestic supply of goods and services in essentially in elastic in the short run, excess liquidity is likely to result in substantial inflationary is like...
