ABSTRACT

Sun-dried bricks (adobe) are out dated to many people. However, statistics show that one fifth of the world’s population uses this material to build houses. The cost of better, alternative building materials are high. Therefore, there is need to improve the quality of sun-dried bricks.  Laboratory experimental procedures are used to determine the specific gravity of the clay, plasticity Index, strength, shrinkage, cracks, and weight of natural clay mixed with Rice Husk Ash (RHA). Results showed that the average specific gravity of the clay is 2.65; shrinkage, plasticity, and cracking of the clay were improved in the composites. However, the compressive strength of clay was not improved by the addition of RHA.

Key words: Clay, Rice Husk Ash, Composites, Shrinkage, Plasticity Index

ABSTRACT

This paper is to determine the drilling bit performance, using cost per foot and breakeven equations.Opukushi-38 well of Shell Petroleum Development Company(SPDC) was used as a case study.Nine drill bits were used to drill this well to a total depth of 13,500ft.They were evaluated using cost per foot and breakeven equation base on their makers and their average cost per foot was calculated.From the results obtained, the average cost per foot for Hughes security, smith and redhcal bits were $34.57/ft,$11.441/ft,$36.35/ft and $39.77/ft respectively.Base on evaluation of bit performance using cost per foot,it could be said that Hughes bit with $34.57/ft has better performance than the other bits since it has the lowest cost per foot.If Hughes bit were used in Opukushi-38 to drill to total,a total cost$6,000 will drill for 75.3hours to produce forage of 2,455.2ft in order to breakeven the cost per foot or less of Hughes with the best performance in the offset well.

ABSTRACT

This paper covered major aspect of concrete mix design as the quality control measure of concrete production, using American method of concrete mix design procedure. It is aimed at highlighting the important of designed concrete as compared to an ordinary ratio analyzed concrete in concrete production for any civil/structural concrete work. This is to analyze the merit and demerit of designed and control of concrete production as required by BS 8110 in structural requirement. It equally include the whole laboratory test analysis, to determine the physical and geotechnical properties of the materials needed for the mix design in order to attain the required data for the design procedure, in accordance to the parent material types and location, and the specific density of the designed concrete, that will be suitable, adoptable, durable, economical, workable and generally safe for the structural design objective of the weather condition in any specified locality. This is equally aimed at controlling the rate of structural failure in Nigeria as a nation an this regard all factors that may lead to failure of concrete structure were generally treated. The design covered concrete grade 25N/mm2, 30N/mm2 and these were designed to attain the required strength grade after 28 days of curing specially with water as the minimum strength. Basically the designs were done with Burham cement as one of the Brand of ordinary Portland cement. It was equally considered as a factor that all the grade of concrete designed for, should achieve 65% strength after been cured for seven days in water. The individual result of the design mix were adequately presented and have shown that generally mix design of concrete before production as measure of quality control of concrete work is very important in any civil project either for Government and individual. Quality control should be applicable, to control structural failure.

ABSTRACT

A study was conducted to find out the possibility of replacing cowpea with pigeon pea and soybeans in the production of an acceptable pudding (‘’Ofuloju’’).Flour was produced from cowpea, pigeon pea and soybeans and evaluated for proximate and functional properties. Pastes were also produced from cowpea, pigeon pea, and soybean and processed into Ofuloju and were evaluated for sensory parameter. The moisture contents of soybean, cowpea and pigeon pea were 9.01±0.01%, 10.28±0.01, 11.99±0.01 respectively, ash content of the samples ranged from 3.15±0.00% to 3.99%±0.00 for cowpea and soybean, Fat content of the samples are1.65±0.00% (pigeon pea), 2.49±0.01 (cowpea) and 19.45 ±0.10% soybeans. The result of the crude fibre showed that pigeon pea had the highest content (4.18±0.00%) while cowpea had the lowest (2.20±0.00%). The protein content of soybean had the highest (44.99±0.00%) while pigeon pea had the lowest protein content (19.93%). The result of the functional properties showed that bulk density ranged from 0.5416±0.00g/ml (soybean) to o.6900±0.01% (pigeon pea). Foaming capacity were 2±0.001% (pigeon pea), 6 ±0.01% (soybean), 8±0.02% (cowpea). Foaming stability showed that cowpea had the highest (72.22± 0.01%) while pigeon pea had the lowest.The cooking time of the pudding (Ofuloju) differs; cowpea had the fastest cooking time (45 minutes), pigeon pea (1 hour) while soybean has the longest cooking (1 hour, 30 minutes).T he result of the sensory assessment shows that Ofuloju produced from pigeon pea was better accepted interms of colour, taste, texture, aromal and overall acceptability than Ofuloju produced from soybean and cowpea. This study showed that the characteristics of Ofuloju produced from pigeon pea was similar to Ofuloju produced from cowpea; therefore, pigeon pea may be used as an alternative in the production of Ofuloju

 ABSTRACT

Entrepreneurship is today the most vital instrument of national development in any economy. In this regard, Nigeria is not an exception. For any nation to achieve its national objectives, entrepreneurship must have an important role in its education policy. The link between entrepreneurship and functional education is a necessity, if Nigeria is to realize it objective of becoming one of the 20th most developed nations by the year 2020. The paper examines the entrepreneurship content of the nation’s education policy, entrepreneurship education in Nigeria and what is required to attain the vision’s objectives. The study used content analysis method. It concludes that there is the urgent need to revise the education policy in order to more entrepreneurship content to the policy’s implementation.

The training and development of human resources in any organization be it public or private is widely acknowledged as a realistic step toward enhancing job performance.  Manpower training is therefore, a field that needs special attention at all times in human history.   Human resources are active agents that accumulate wealth for the nation, exploit material resources, build social, economics and political organisatiions and assist in national development of a country.  That is, if the public service has sufficient and effective personnel, with suitable and relevant skill and knowledge, there is every possibility for achieving its aim and objectives. Lack of provision of accommodation and working facilities have a great effect on manpower efficiency and effectiveness in public organistaion in Nigeria.  It could be said that manpower development for sustainable job performance is designed to improve the overall effectiveness of managers in their present position and to prepare them for greater responsibility when they are promoted.  Infact the mere acceptance of the idea of training and development of manpower for sustainable job performance by policy makers and planners does not make things happen,  organization can not succeeds without the great inputs of its human resources.  The public organisation secure the confidence of their employees by motivation, good salary structure working materials, organizing seminar, workshop, inductive raining for sustainable job performance in the country.

ABSTRACT

Since the debasement of money emerged, particularly during the 17th and 18th centuries when precious metals were still being used as coins in continental Europe & North America, whereby governments and monarchs often combined gold coins with other metals such as silver, copper or lead and reissue them at the same nominal value, the intrinsic value attached to each metallic coin declined. Consumers who used them had to pay higher prices (more coins) for the same quantity of goods and services than was the case in the past. Price inflation was therefore, a fall-out of monetary inflation. It is in this context that price inflation is essentially considered as a monetary phenomenon. But, does it mean that inflation can only be controlled through monetary policy? This paper, answer in the negative. Reviewing literature on conceptual and empirical issues on monetary policy, inflation, and fiscal policy; this paper posits that inflation in Nigeria though a monetary phenomena is essentially supply oriented in nature and can best be controlled by fiscal policy measures. It therefore suggests that government should put in place the necessary infrastructures that would lower the cost of production (supply side-economics) in the economy and enhance output thereby achieving its inflation targeting regime.

ABSTRACT

This paper examines privatization of public enterprise; in Nigeria as a neglect of government social responsibility. It also looks at privatization of public enterprises as a violation and abuse of section 16 subsections 2c and 3b of the 1999 constitution which is the fundamental principle of state objective which says the state can owned and control its resources for the benefit of its citizens. This perhaps becomes another thing as the state resources are been controlled by some political cabal known as private sectors. This creates hardship to the poor. Privatization of public enterprises  is no longer friendly with the labour as it; introduction lead  to mass retrenchment of workers in the public sector previously owned by the government.  Privatization of public enterprises in Nigeria has brought poverty, unemployment and human misery to the lives of citizens. This research paper adopts Marxist theory of post colonial state for its analysis.
