Effect of optimum processing conditions on total polyphenols, antioxidant activity and FTIR spectra of kodo millet (Paspalum Scrobiculatum)
The various processing treatments like soaking, germination, boiling, steaming, roasting and fermentation are known to affect the chemical composition and improve the nutritive value of foods. Hence the present study was planned with the objectives to optimize the processing conditions and to study the effect of optimized conditions on total polyphenol content, antioxidant activity and FTIR spectra of kodo millet. The optimum time for soaking, boiling, steaming, roasting, germination and fermentation was determined by analysing the changes in moisture content, equivalent diameter, bulk density, reducing sugar and total sugar content. The optimally processed kodo millet was analysed for its total polyphenol content, antioxidant activity and FTIR spectra for identification of unknown polyphenolic compounds. Result revealed that kodo millet could be soaked for 76-78 hours, boiled/steamed for 25-30 minutes, roasted for 15-20 minutes, fermented for 48 hours at 37°C and germinated for 72 hours at 37°C and 50% RH optimally. The various processing methods significantly affected the total polyphenol content. Among the processed samples, the highest polyphenol content and antioxidant activity was noted in germinated and boiled grain respectively. FTIR spectral analysis revealed the presence of polyphenolic compounds especially with mono substituted benzene ring in all processing conditions.

Effect of seasonal variations of aquifer Characterisation and resistivity values
A geoelectric investigation involving sixteen vertical electric soundings with maximum current electrode spacing of 650m was carried out at Obiaruku, Delta State, Nigeria and environs. This was aimed at determining the effect of seasonal variations of aquifer characterization and resistivity data. The resistivity data got from the survey is interpreted by curve matching and computer iteration techniques where the geological model parameters and curves were obtained. Three to six geological layers were observed within the whole locations. The results show that there was a slight difference in the apparent resistivity values between wet and dry seasons which could be attributed to the degree of wetness (especially the topsoil) experienced during the rainy season. The aquifers, number of layers, curve type and shape, layer thicknesses are approximately the same values for both rainy and dry seasons.

Effect of traffic density on soil along Nwanga-Ekoi- Mfamosing road cross river state, Nigeria
The effect of traffic density on soil along Nwanga-Ekoi- Mfamosing road Cross River State, Nigeria, was carried out. The spatial variability of pollutant concentration in high traffic density areas exerts an importance influence on some road deposited sediment characteristics due to activities of people and vehicles. The movement of vehicles from one point to another may spread contaminants on the soil. The main processes of the movement of vehicles can spread contaminants on the soil which may include wearing of car parts (Exhaust pipes, tires, brakes, engines block, leaking of oil and corrosion metal parts). These processes may release heavy metals on the surface of the soil along roadsides. The heavy metals were analyzed using Atomic Absorption Spectrophotometry (AAS) and paired sampled T-test method were used for the statistical analysis of soil along High Traffic Density (HTD) and Low Traffic Density (LTD) sites. The results from AAS revealed that heavy metals concentration in HTD were Calcium 0.041, Copper 0.037, Iron 0.037, Manganese 0.086, Nickel 0.033, Lead 0.207 and Zinc 0.11 respectively. Heavy metals concentration in LTD were Calcium 0.007, Copper 0.008, Iron 0.007, Manganese 0.007, Nickel 0.005, Lead 0.003 and Zinc 0.003 respectively. The result for the ANOVA analysis shows significant difference of (F=9.1, p<0.05) between HTD sites and LTD sites. The paired sample t-test also indicates significant difference of (t6=2.9, p<0.05).This implies that heavy metals concentration in HTD sites were higher than heavy metals concentration in LTD sites. Therefore, high traffic density sites increases soil heavy metals concentration along roadside.

Effect of various curing conditions on compressive strength of HPC
High Performance Concrete (HPC) is that concrete which meets special performance and uniformity requirements that cannot always be achieved by conventional materials, normal mixing, placing and curing practices. The grade of concrete selected was control mix (CM) of M80. Investigation was carried out on mixes of partial replacement of cement with metakaolin (MK) 10% and silica fume (SF) 15%. Regression analysis equations were developed for each type of curing based on compressive strength and age of concrete (7, 14, 28 and 56 days). In this study the effect of various curing conditions on compressive strength of HPC were studied. The various curing conditions adopted were normal curing (NC), wet cover curing (WCC), membrane curing (MC) and accelerated curing (AC). Normal water curing includes immersion of concrete cubes in water. Wet cover curing includes covering concrete with burlap. Membrane curing includes application of wax coating on concrete cubes. Accelerated curing includes application of heat at ordinary pressure. The overall finding of this study suggests that concrete should be cured by water curing to achieve a better compressive strength.

Effects of Financial Planning on the Performance of Transport and Logistics Firms in Mombasa County
This research project sought to determine the effects of financial planning on the performance of transport and logistics firms in Mombasa County. The general objective was to establish the determinants of performance. The independent variables under consideration were: fund allocation, external funding, fund control and budgeting. These independent variables created the basis for the specific objectives under review as follows: to find out how the fund allocation influences the decision to growth and profitability; to establish how the degree of external funding influences the decision of firms to growth and profitability; to find out how budgeting affects the decision to growth and profitability; and to find out how fund control the decision to growth and profitability. Transport firms in Mombasa have grown in importance in the economy of the region during the last couple of decades. Although transport firms are growing speedily they face a range of challenges which work against their progress. Lack of financial knowledge is been a major setback to transport firms’ progress. Inefficient financial planning may damage transport firms profitability and, as a result, complicate the difficulties of transport firms’ growth. Conversely, efficient financial planning will help transport firms to strengthen their profitability and, as a result, these difficulties can partly be overcome. This study is motivated by the need to determine the financial planning practices used by transport firms and their impact on the financial performance of the transport firms. The target population of this study will be 102 transport firms operating in the Mombasa County. A modified Liker scale questionnaire will be developed divided into three parts. A pilot study will be carried out to refine the instrument. The quality and consistency of the study will further be assessed using Cronbach's alpha. Data analysis will be performed on a PC computer using Statistical Package for Social Science (SPSS Version 22) for Windows. Analysis will be done using frequency counts, percentages, means and standard deviation, regression, correlation and the information generated will be presented in form of graphs, charts and table.
