ABSTRACT

The study investigated the effects of inorganic fertilizers (Nitrogen and Copper) at different levels on the microbial numbers in acid soil grown with Khaya ivorensis in a green house experiment. Results show that the microbial numbers (fungi plus
bacteria) increased with N application up to 100ppm and Cu application up to 10ppm.The combined application of N and Cu led to the greatest microbial population. High application of N at 400ppm and Cu at 20 and 40ppm however
reduced the microbial population in the treated soil.

ABSTRACT
Due to the high rate of carbohydrate intake which could lead to a disease disorder called diabetes, hence the need to evaluate the efficacy of bitter leaf extract on the reduction of blood sugar (diabetes). The amount of sugar present in six starchy food:
cassava flakes, yam, maize flour, cassava starch, fufu paste and bread was evaluated and the effect of bitter leaf extract on the reduction of blood sugar was taken. The result revealed that for the amount of sugar present in each food, cassava flakes had 0.75g, yam 0.43, maize 1.52, fufu paste 0.54, wheat bread 3.20
and cassava starch 1.0 while the result on the effect of bitter leaf extract on the reduction rate of sugar, the result shows that for the deep blue colour to disappear, it took cassava flakes 6 minutes, yam 5 minutes, maize 20 minutes, fufu paste 5.5 minutes, and bread 30 minutes,. The research shows that yam had lowest amount
of sugar and also had the least time for the disappearance of deep blue colour. It is therefore recommended that yam should be taken by the diabetic patients and the public in general to avoid the occurrence of diabetes in the developing countries
especially in Nigeria.

ABSTRACT

In this paper, an inverter system of 1KVA Power is designed from transformation ratio equations and relay configuration and on to electronic components and devices
that converts DC Supply from Battery to AC Supply suitable for household and office appliance to cater for instability in power supply. The AC supply given out has a relatively smooth Sine Wave required for normal operation of any appliance. The Inverter is designed to operate for a minimum of thirty (34)
minutes, which depends on the ampere hour rating of battery used in the inverter. The charged battery of the 1KVA inverter is capable of maintaining the continuity and quality of electric power supply in a living home with a battery charger using a square wave oscillation, power MOSFET switching circuits and
two lead acidic 60AH batteries. The results of the analysis of the inverter interface are attached as appendix.

ABSTRACT
Osteoarthritis (OA) is the commonest articular disease in the elderly people. It
represents a heterogenous group of conditions resulting in common histopathological
and radiologic changes. Current view holds that OA is a disease of the entire joint organ
and not of cartilage alone. A prospective study of all elderly patients aged 40 years and
above with knee pain was conducted. Plain radiographs of the affected knee were
requested. People below 40 years and those with traumatic pain or polyarticular
involvement were excluded. The study was carried out in a private rheumatology clinic
over three years (July 2009- June 2012). OA constituted 30.9% of all rheumatology
cases seen over the studied period. Male constituted 30.8% and female made up of
61.2%, with a male: female ratio of 1:2.3. 76.9% presented after one year duration of
onset of pain. Medial compartment of the knee was affected in 76.9% of patients on
plain radiograph. Considerable variation occurred with pain severity and radiographic
findings. 65.4% of the patients were either overweight or obese. Hypertension was the
commonest co-morbid condition (48.1%). The results of knee radiographs should not be
used in isolation when assessing individual patients with knee pain. The clinical
presentations must be considered alongside the plain radiographic findings.

ABSTRACT
Concrete is one of the most widely used construction materials in the world. To
ensure sustainability and a reduction in the cost of concrete, the use of renewable
agricultural waste materials as aggregates becomes desirable. This paper presents
results of a comparative study of the physical and compressive strength of palm
kernel shell concrete (PKSC) and normal weight concrete (NWC) using Portlandlimestone
cement (class 32.5R) and Ordinary Portland Cement (OPC) herein called
Ghacem Extra Cement(class 42.5N). Palm kernel shells were used as lightweight
coarse aggregate in PKSC and granite was used as aggregates for the normal
concrete. The study was conducted in accordance with the British Standards (BS
812, 1990; BS 1881, 1996). Two mixes of ratios 1:1.3:0.7 and 1:1.7:2.5 by weight
were used in the study. The values obtained for water absorption, aggregate impact,
aggregate crushing, specific gravity and Los Angeles abrasion, satisfy the minimum
requirements of aggregates for structural concrete as specified in BS 882, 1992. The
density of the PKSC was about 22% lower than that of the normal weight concrete
for both cement types. Compressive strengths of both PKSC and normal weight
concretes with Portland-limestone cement and Ghacem Extra cement evaluated at 7,
14 and 28-days showed that Ghacem Extra cement produced concretes of higher
compressive strengths than Portland-limestone cement for PKSC and normal weight
concrete. In general, the compressive strength of PKSC using Ghacem Extra cement
compare well with those obtained from other materials used for structural lightweight
concretes.

ABSTRACT

Land is among the most valuable natural resources bestowed on man. His life is a repertoire of efforts to interact with land to provide his needs since the dawn of civilization. However, the riches of land can be destroyed and / or exhausted if mismanaged. It is therefore incumbent on man to adopt a proper land husbandry
procedure to ensure that the resources of land are used to satisfy his needs of today and at the same time conserve some for tomorrows needs. This paper highlights the origin of land tenure system in Nigeria, the desirably or other wise of the land use Act,
main provisions of the Act and the provisions of the Act and the challenges of MDGs. The discourse was able to buttress the view that the land use Act was conceived with noble objectives, but its implementation over the years has been fraught with problems
thereby constituting a dog in the wheel of national development and an impediment to socio-economic growth of the nation.

ABSTRACT

People infected with HIV/AIDS frequently have hematological derangements which include anaemia, Leucopenia, and Thrombocytopenia. In this study, hematological
parameters between malaria positive(+) and negative(–) HIV infected persons referred to ART/HIV laboratory, Abia State University teaching hospital, Aba were compared.
Blood samples collected for haematological assays were run using an automated full blood counter and malaria parasitaemia was determined by blood smear microscopy. A
total of 490 adults living with HIV parasites were examined. Of these 373(76.1%) were found to have malaria while 117(23.3%) had no malaria infection. Haematological analysis of blood samples showed higher mean values of RBC (×1012 /μL)(4.66±4.28 for

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.
