ABSTRACT

Although water is an abundant natural resource, available in the rivers, streams, and wells to meet the needs of people, water of adequate quantity and acceptable quality is not always available to the consumers. This is the problem facing Abraka and its environs. River Ethiope with a catchment area of 493.50km2 at Abraka is naturally drained with stable and well defined slopes, firm bank and bed and very clear water. If the water is properly harnessed and utilized, it can be a boom and of immense value and no small measure enhance the economic, social and industrial well
being of the people of this region. Four years of daily water stage and 20 years simulated river Ethiope watershed run-off coupled with two (2) years stream flow and head measurements were used for the assessment. The result shows a yield of 966.50 × 10􀬺m3, which can be generated from the river per annum. The combined water requirement of Abraka is 28.359 × 10􀬺􀝉􀬷/􀝕􀝁􀜽􀝎. The current water demand and forecasted water demand up
to year 2033 can be met by resources in the basin. This paper also revealed that the water requirement of the towns through which the river transverse can be met.

ABSTRACT

The Fundamental Least Squares Observation Equation Method of Adjustment is reviewed using a case study of a Triangulation network. Four Alternative techniques were applied. They are: Simultaneous, Sequential, Phase and Combined (Phase &
Sequential). Based on computational results obtained from these techniques suggestions were made as to the merit of one method over the other.

Background

Mammography is an important radiologic modality using ionizing and non-ionizing radiation in medical imaging of the breast as well as for breast examination, screening and detection of breast cancers. The procedure is however known to be associated with discomfort and pain which could otherwise impact adversely on
patient participation. Hence, several management strategies including verbal communication which is given prior to examination have been adopted to alleviate associated pains and discomfort.

ABSTRACT

Electrical measurements of insulation in air and in oil were performed on four different types of insulating materials – two cellulose based and two polymeric materials. Extensive measurements were carried out in air and in oil on the selected
materials. Results of their breakdown voltages show higher values for insulations soaked in oil than those measured in air. It also shows that cellulose based materials have better performance in oil than polymeric, and they equally show a recovery rate of up to 70% in oil. All materials tested show averagely high breakdown strength for a long time (≥5hrs) before deterioration under stress. To confirm this, the materials were maintained in transformer oil at 100 deg. Celsius for five hours and then subjected to a high dielectric strength.

ABSTRACT

Sustainable building is an environmental approach to the creation of new structures as well as remodeling existing once; hence, the concept of green buildings. Green buildings seek to make the best use of materials that are sustainable or that are
renewable in nature. The attempt to reduce the collective environmental impact during production of building components, during the construction process as well as during
the life cycle of the building: hearting, electricity, use etc. motivated this work. The purpose is to highlight the material importance, its suitability and applications in public
buildings.

ABSTRACT

This paper presents the results of the investigations on effectively integrating natural gas to getting the best economic values from marginal fields. Effective organograms and assets management are major keys that will drive the exploitation and effective
monetization of natural gas from these fields. Natural gas is an important input to the success of major sectors of the economy, and therefore, should be properly exploited
from marginal fields.
