ABSTRACT This study examined the impact of direct tax on foreign direct investment in Nigeria within the period of 1990 to 2017. The long run stability of the variable was tested and it was found that the data were stationary and co integrated. An error correction test was performed to detect the speed of... Continue Reading

ABSTRACT Supervision has become indispensable for it is an impetus enabling headmasters to maintaining order and sanity in schools particularly in senior high secondary schools. It has therefore become needful that in era where people would always want their way despite law and order, proper supervision has become appropriate to help sustain... Continue Reading

The power system is a highly nonlinear system that operates in a constantly changing environment; loads, generator outputs, voltage controllers, transmission lines, topology, and key operating parameters change continually. The behavior and output of the generators can be affected in a transient conditions. This transient condition can change the... Continue Reading
