This Paper on the Modeling and simulation of 58 Bus 330k Nigeria Network is a complete modeling of Nigeria interconnected Power network. Its objective is to determine the structure of Nigeria Power network, to model a power flow on transmission lines and to develop a Simulation Model and the Simulation of 58 Bus Nigeria 330kv Transmission Network. The research material for this research is the 58 buses Nigerian 330-kV Transmission Network which shows that The Nigerian Transmission grid is made up of interconnected network of 6702 km of 330-kV that spans the country nationwide . The system may be divided into three geographical zones-North, SouthEast, and the South-West. The North is connected to the South through the one-triple circuit lines between Jebba and Oshogbo while the West is linked to the East through one transmission line from Oshogbo to Benin and one double line from Ikeja to Benin. The transmission grid is centrally controlled from the National Control centre (NCC) located at Oshogbo in Osun State, while there is a back-up or Supplementary National Control Centre (SNCC) at Shiroro in Niger State. The 58 bus Nigeria 330kV transmission line network was modeled in PSAT 2.1.8. The simulations of Nigeria 330kV was solved using the power flow equations and Newton – Raphson method of load flow solution. Results shows that ordinary line diagram of the 58 Bus network of Nigeria in a line diagram without full interconnections of the network that may not be used for further studies of the Nigeria network. But the simulated network in a PSAT Model for 58 Bus Nigeria 330 kV Network without a device like the flexible alternating current transmission system ( FACTS) Device gave provisions for insertion of devices that may help for future studies like identification of violated voltages on the network, insertion of devices like Static Synchronous Series Compensator, unified Power flow controller, and Static compensator (STATCOM). Therefore it is highly recommended that a Power system Analytical Tool (PSAT) should be used in the modeling of Nigerian Power network that can be use for further studies.

There is a knowledge gap on the effect of velocity and hydrogen potential (PH) on the corrosion of medium carbon steels in fresh water and the desire to provide fundamental data for the behavior of medium carbon steel in various environments form the basis for the investigation. The corrosion study was carried out every 14days for a total of 98 days using weight lose method. The factors which are believed to affect the corrosion of metals such as the PH of the environment, velocity of the flow water, and possible presence of sulphate reducing bacteria (SRB) were investigated.

This work aimed to design and fabricate a portable electric Can Crusher machine to reduce the scrap volume and use the Cans so that carrying them to the recycle site becomes easy. Now-a- days, a large number of cans are used in hotels, canteens etc. and a large volume of space is required for storing or dumping the used Cans. This project includes fabrication of a Can Crusher using single slider crank mechanism which will reduce the volume of cans at least 70%. This report demonstrates the necessary calculation, assembling and fabrication of the machine. Under this project work, two Can Crushers have been constructed. The earlier one, made during the period of 7th semester was manually operated. The model is then upgraded to an electrically operated one. Finally, a comparison between the two Can Crushers, i.e. manually operated and electrically operated, is made, regarding their efficiencies, cost of construction etc, and presented here in this report.
