Abstract

Acquisition of employable skills for self-reliance have received increasing attention in the recent past in Nigerian Educational Policy. An important ingredient for success in the on-going efforts by the government at alleviating poverty, minimizing corruption, attaining food security, achieving uninterrupted electric power supply, reducing unemployment of youths and keeping pace with the dynamics of societal changes and emerging technologies, is the effective delivery of qualitative technical and vocational education courses. This paper highlights constructivism in instructional delivery as what most present-day technical teachers should adopt: a framework in which the role of the teacher becomes that of a facilitator. The paper posits the need to strengthen the vocational education curriculum, adequately supply of instructional materials and the motivate the teacher who is at the centre stage of all the activities in skills acquisition. Some recommendations to government were also made.

Abstract

Concrete is the most widely used construction material in the world, because of its availability and versatility. The increasing demand for the durable concrete that is environmentally friendly is growing by day. Rice husk ash proved to be one of the supplementary cementing materials that supplement cement and produce a durable concrete that is environmentally friendly. Sulphate attack on concrete makes the concrete to suffer from deterioration and becomes less durable. This paper investigates the effect of different mix ratios of rice husk ash blended cement on the resistance to sulphate attack on concrete. One hundred and eighty (180)of rice husk blended concrete cubes of grades 25, 30 and 35, with the nominal mix ratios of 1:2:4;  and 1:1:2 were cast and cured for 28 days. Later on, the cubes were immersed into water with 0%, 2.5%, 5%, and 10%, concentrations of sulphuric acid (aggressive media). Twenty per cent(20%) replacement was used throughout the research work. The zero per cent (0%) concentration wasused as a control, so as to establish a basis for comparison of the effect of the aggressive media on the rice husk blended cement. Three cubes from each of the concentrations of the acid-water were tested for compressive strength at 3, 7, 14, 21 and 28 days of acid curing for each of the grades. It was observed that the richer the mix ratio of the cement-rice-husk-ash blending the better the resistance to sulphateattack. The statistical analysis of the data indicated that, the F-values of the compressive strengths of the concrete at 95% confidence limit are 6.48, 5.91, 5.59, 5.23 and 4.88 for 3, 7, 14, 21 and 28 days of aggressive media curing respectively, these values are greater than 4.26. This indicated there is significant difference in resisting sulphate attack by different grades of concrete, that is, the richer the grade of concrete, the more resistance it offers to sulphate attack significantly.It was also observed that, the higher the concentration of the acid and the longer the period of curing in aggressive media, the higher the attack on the concrete.

 Abstract

  The study was designed to investigate the performance of West African Dwarf (WAD) Goats grazing under oil palm plantation. Twenty (20) WAD Goats about six months old were used for the study. They were allotted to two treatments consisting of two replicates of five Goats each. Treatment 1, served as the control with (WAD Goats were allowed to graze in a paddock under the canopy of an oil palm plantation). While treatment 2 contained group of WAD Goats were allowed to graze outside the oil palm plantation (the experimental area). Water were provided at all times. The study lasted for twelve weeks. The results indicated that the group of WAD Goats fed under the oil palm plantation (T1) made a significantly (P<0.05) higher mean daily weight gain value ( 9.85g) over the mean daily bodyweight gain value ( 7.74g) recorded for the WAD Goats which roam about grazing outside the oil palm trees canopy. The weed in the paddock under the plantation was very mush reduced. In conclusion, WAD Goats grow faster and control weeds if reared under oil palm plantation. The rearing of WAD Goats under the oil palm plantation is therefore recommended.

Abstract

Greater Jos like other fast urbanizing towns and cities in Nigeria are faced with a multitude of problems ranging from poor state of roads, insufficient water and electrical power supply, inadequate municipal solid waste management and other related ones. Among this multitude of problems municipal solid waste management appears to be the most prominent in recent years. Municipal solid waste is seen in huge heaps on any piece of unused land, around buildings and in the open market places. Living with solid waste littered around appears to be an acceptable way of life among the people in the municipality in recent years. The work reported in this paper involves a study of planning constraint to residential municipal solid waste management in Greater Jos municipality in Nigeria. A site-specific study was carried out to estimate the quantity of residential municipal solid waste generated in the municipality through waste management agency–Plateau Environmental Protection and Sanitation Agency (PEPSA). Structured questionnaires were applied to collect primary information such as size of households, educational level, and monthly income from households. The results obtained indicated that of poor education, poor income of residence, insufficient funding, institutional structure, social disposition and cultural norms are the major planning constraints to municipal solid waste management in the municipality in which solid waste is in crisis stage. Feasible suggestion for improved municipal solid waste management based on the prevailing planning, educational and socio-economic state of the institutions and residents in the municipality has been presented.

  Abstract

Chloroquine had been reported to have a depressant effects on cardiac muscle and chloroquine like quinine,reduces excitability and conductivity of cardiac muscle ( Taylor and Francis 1987).

It is therefore necessary to study the effects of chloroquine on the heart .This study was designed to determine the effects of administration of chloroquine on the heart. Ten male rats were exposed to chloroquine injection intra peritoneally/IP) for three days. The treated rats received

0.125ml/100g body weight of chloroquine phosphate injection intraperitoneally. Control rats received the same amount of normal saline intraperitoneally.The histology of the chloroquine treated heart was compared with the controls. It was observed that chloroquine caused malformations this tissue. Investigation confirmed defects in microscopic structures.There were few blood vessels in the treated rats compared with controls and there were constrictions in the structures of treated rats compared with controls.Stereologically, the estimated absolute volume V=VV(structure) X V(ref) was determined and compared chloroquine caused a reduction in the absolute volume of the heart blood vessels (coronary artery) compared with controls.

ABSTRACT

The study explores how the vast spectacular natural tourist attractions found in Plateau state are being abused. The research methodology used is literature search, face to face oral interview and direct field observation. Data collected were analysed using the descriptive statistical technique.  From the list of the tourist attractions of the state, the researchers identified and purposely sampled some attractions for the survey. Findings show that only few of the natural tourist attractions of Plateau state have been designated as protected resources and are under management control. Most attractions are however yet to be designated as protected resources and are thus not under any management control. Unfortunately, both the designated protected  and the unprotected resources have all come under serious anti-conservation acts such as illegal farming, illegal grazing, poaching, wood and fuel extraction (logging), quarrying, indiscriminate inscription, waste dumping, bush burning, and mining activities. Most of the abuses come from the local communities around the attractions. These local communities gave reasons for their irrational exploitation of tourism resources to include non ompensation, non involvement, non benefit and non alternative sources of livelihood. The way forward as advocated by the researchers is to fully address these issues raised by the local communities. The local communities will then be mobilized to be in the fore front of protecting and conserving these attractions for sustainable tourism.

Abstract

The distribution of Heavy metals around the Soil in Rumuokoro Municipal Waste Dumpsite was studied. A transverse measuring about 200m away from the dumpsite was cut, and soil samples were collected to the depth of 0.5cm, 5-15cm and 15-30cm at the distances of 5m, 30m, 60m, 90m, 120m and 200m away from the dumpsite. A total of Eighteen (18) samples were collected and analysed for Heavy metals Using Atomic Absorption Spectrophotometer (AAS). The mean concentration for various heavy metals from the 200m (control) point to 5m away ranges:- Cadmium (Cd) not detected to 0.04 (µglg), Chromium (Cr) 0.02 to 0.19 (µglg), Iron (Fe) 0.01 to 0.93 (µglg), Nickel (Ni) 0.01 to 0.52 (µglg), Lead (Pb) 0.01 to 0.65 (µglg),  and Zinc (Zn) 0.01 to 0.39 (µglg). The result showed that the concentration of heavy metal decreased as the distance away from the impact point increased, and also the concentration decreased down the profile. The result also showed that from samples collected at 200m away, all others concentrations were above the permissible limits established by regulatory agencies, thereby indicating Heavy metal pollution in the affected area.

Abstract

Significant binding of chloroquine occurs in the liver, kidney and spleen (Taylor and Francis 1987).For a very short period of three days, ten male rats were exposed to chloroquine phosphate injection intraperitoneally /IP) for three days. The treated rats received 0.125ml/100g body weight of chloroquine phosphate injection intraperitoneally. Control rats received the same amount of normal saline intraperitoneally.Stereologically, the parameters measured for the spleen was compared with controls. The estimated absolute volume V =Vv (structure) x v (ref) of the white pulps of the fractions was determined and compared. In the spleen chloroquine caused a reduction in theabsolute volume of the white pulp when compared with controls.

Abstract

 Crude Oil contamination on a soil environment is known to affect soil quality through changes in soil pH, air temperature, soluble plant nutrients and disruption of metabolic processes of soil microorganisms, etc, thus vigor of mineralization of plant nutrients. Biostimulation and bioaugmentation methods of soil remediation are often employed to remedy contaminated soils. Effectiveness of these methods are known to differ therefore, this experiments was conducted to evaluate available phosphorus (Av.P), total nitrogen (N) and potassium (K) in a bioaugmented and biostimulated crude oil contaminated Coastal Plain Sand in Southern Nigeria. Results showed that the highest Av.P (640ppm) and %N (0.16) were recorded in the unseeded soil in 5% pollution level amended with poultry manure (PM). In week nine (9), potassium decreased with increase in organic carbon percent with the highest (1.22 and 0.64cmol/kg) recorded in the PM amended soil at week 1 and at week 9 respectively. This study suggests that 2 -5% pollution level contaminated Coastal Plain Sand should be amended with PM without bacterial seeding while above 5%pollution level contaminated Coastal Plain Sand should in addition be seeded with Pseudomonas aeruginosa
