Design of the study is Instrumentation. Eight research questions were posed and two hypotheses were formulated to […]
NIGERIA’S CONTRIBUTIONS TO DEMOCRATIZATION IN SIERRA LEONE, 1995-2005 ABSTRACT This study problematizes the issues of good neighbourliness and democratization in Africa, and analyses the effects of Nigeria’s economy on these. Focusing on the relationship between Nigeria’s foreign policy and the democratization process in Sierra Leone, the study examines the challenges Nigeria faced in trying […]
Design, Construction And Performance Evaluation Of A Magnetic Sieve Grinding Machine ABSTRACT Technology of milling and grinding machine is one of the simplest methods of processing agricultural raw materials alternative to the traditional methods of grain/tuber processing using stone, mortar and pestle. However, machines constructed using metal plates results in tearing and wearing away […]
[…] contaminated soils. Hence, this research was aimed at investigating the effects of particle sizes on bioremediation of crude oil polluted sandy soils. Six different soil samples were sieved using the B.S sieve sizes. The sieve sizes were classified into X and Y such that X is fine to coarse sand while Y is very […]
POTENTIALS OF PIPER GUINEENCE (SCHUM AND THOM) AND MONDORA MYRISTICA (GAERTN) FOR THE PROTECTION OF STORED MAIZE (ZEA MAYS) AGAINST SITOPHILUS ZEAMAIS ABSTRACT Undamaged and uninfested maize grains were hand picked, packaged in moisture proof package and disinfested in the deep freezer for 96 hours. Thirty six sets (500g per set) of disinfested maize […]
[…] commitment to make Africa the centre-piece of the countryâs foreign policy, Obasanjo continued with Nigeriaâs leading role in the maintenance of peace and conflict resolution in Liberia, Sierra Leone, Togo, Sudan, etc. This work is a review of Nigeriaâs foreign policy during Olusegun Obasanjoâs second era and its impact on Nigerian citizens. It examined […]
[…] (SDS – PAGE) is a technique commonly used for the separation of proteins according to their molecular weight, based on their differential rates of migration through a sieving matrix (a gel) under the influence of an applied electrical field. SDS – PAGE was used in assessing the genetic diversity among twelve accessions of African […]
[…] work sought to analyze the impact of institutional quality, government expenditure on economic growth, using a panel data analysis for four selected West African Countries (Nigeria, Ghana, Sierra Leone and Burkina Faso) from 2005 to 2013. The study found a positive and significant relationship between some institutions – economic institutions, on economic growth whereas […]
[…] a descriptive survey design, an item structured instrument which was designed to reflect a five (5) point Likert Scale of strongly agree, agree, disagree, strongly disagree and undecided was used to elicit data from the respondents. The validity and reliability tests conducted for the instrument indicated that the instrument for data collection was very […]
[…] of a project needs to be subjected to a proper evaluation, with respect to the key pertinent issues (client objectives). The types of project delivery methods was sieved first through an extensive literature review; and about Nine (9) methods were identified. An evaluation on the delivery method is further carried out using related literatures. […]
[…] Gari without African yam bean seed flour served as the control. Fermentation was done for 2 days after which the samples were dewatered. The dewatered samples were sieved, toasted and evaluated for chemical composition and functional properties. The level of TAYBSF and stage of inclusion had significant (p < 0.05) effect on the composition […]
[…] clean bags and mixing dewatered mash with quantity of water that is 10 times the volume of mash. Other practices adopted by majority of the farmers included sieving of mash with muslin cloth, sedimenting, decanting and collection of starch, sun-drying of starch on raised platform or oven-drying at a temperature of 50oC, milling of […]
[…] and de-pulping of the peels. The seed cotyledons and peels were blanched at 1000C for 2,4 and 6 mins, wet milled with water in 1: 1.5 ratio, sieved with muslin cloth to obtain the extracts which were pasteurized at 800C for 10mins and stabilized with 0.2, 0.4, 0.6, 0.8 and 1.0 (g/litre) concentrations of […]
[…] precipitation of ~2600 mm and ~50 mm respectively. However, there are notable biases in southern Cameroun where precipitation is overestimated up to 90 mm and the Guinea- Sierra Leone coast where about 90 mm is underestimated. Despite this, there is a significant positive correlation between NorESM-simulation and GPCP-observed precipitation over the entire West Africa, […]
[…] underlying lithologies. A total of 47 and 60 soil samples respectively were collected along the same roads and each subjected to grain size distribution test using wet sieving to determine the soil group dominating the soil occurring on each lithologic unit. Thirty nine (39) and fifty (50) samples from the above were selected and […]
[…] natural soil (NS) at depths 1.5, 2.0, 2.5, 3.0 and 3.5 m were obtained from six test points in Kaduna, Nigeria. The soil samples were subjected to sieve analysis, Atterberg limits (liquid limit, plastic limit, plasticity index and shrinkage limit), compaction, consolidation, triaxial, specific gravity tests as well as chemical characterization. Data treatment of […]
[…] more decentralized system where power is injected directly to a distribution network (embedded generation). Nigeria is not left out in this trend. In this assessment study, the Siemens’ PSS/E software is used to run the Newton-Raphson load flow program to see the effect of EG on loss reduction and voltage profile improvement while comparing […]
[…] distribution system is chosen for this work because it provides realistic sizes and locations for shunt capacitors on primary feeder at a low computational burden. The Gauss- siedel method was used for load analysis while simulation work was done using MATLAB software. The variation of the load during the year is considered. The capital […]
