ABSTRACTIn this project, Partial Least Square Regression was compared with Ordinary Least Square Regression (OLSR) to handle the problem of multicollinarity and small sample size on all Nigeria Insurance Company’s expenditure data. The prediction methods have been compared for efficiency through Root Mean Square Error (RMSE) and Mean Square Error (MSE). It is found that in this project Partial Least Square Regression (PLSR) provides better prediction as compared to the Ordinary Least S...
Outliers are every day problems encountered in all spheres of life. This work addresses the different methods of labelling outliers and as well highlights the applications of outliers in real life processes

INTRODUCTIONNowadays, it seems like almost every one own a car and in fact, we can say that each house have at least one car. But the more is approximately three cars per house. This figure shows that car is very important to people’s life as it completed the cycle of living. Without a car, it is almost impossible to move from one place to another especially for those who are always mobilise in their jobs. Car simplified our life and it makes time to be more valuable as we can save much tim...

200%;font-family:" times="" new="" roman","serif""="">ABSTRACTA Linear Variable Differential Transformer (LVDT) was constructed having a primary mso-bidi-font-size:14.0pt;font-family:" times="" new="" roman","serif""="">winding of 245 turns and two secondary windings of 100 turns each. The devicewas calibrated with a graduated cylindrical rod. The graduated rod wheninserted between the hollow tube which has the windings gave output voltages of±0.046V, ±0.51V, ±0.088V, ±0.155V, ±0.2...
ABSTRACTThis study reviewed the importance of hand washing and health benefits derived from the practice and also highlighted the consequences of not observing strict hand washing practice. Swabs from primary school pupils showed cfu mean total viable count of 1.60 x 104, 1.50 x 104, 1.60 x 104 and 1.7 x 104 across the four schools. Salmonella spp., Staphylococcus spp. and E. coli were the most sensitive microbes to the antibiotics used while Ciprofloxacin and Gentamicin were active across th...
ABSTRACTThe toxicity of heavy metals to humans as a result of long term exposure to pollutants consumer products such as cosmetics and other pollutants has been established. In this study, the levels of heavy metals in different cosmetic products commonly used among Kaduna Polytechnic students were assessed. The cosmetics were analyzed for heavy metals (chromium, copper, nickel and lead) using Atomic Absorption Spectrophotometer (AAS) after digestion with concentrated HNO3 and HCl acid...
ABSTRACTNickel amine carboxylate complexes were synthesized by reacting Ni(ii)chloride with ammonia, malonic and tartaric acid, which formed Nickel amine malonate and Nickel amine tartarate of blue and green crystal and the percentage yield are of both complexes are 62.65% and 62.83% respectively. The decomposition temperatures were 218o C and 203oC with percentage moisture content of 8.0% and 21.50%. The carboxylic acids and the synthesized complexes were tested for antibac...
ABSTRACTMilk has been known to be highly nutritive ad thus a good medium for bacteria growth and vehicles for transmission of food borne infection. A total of 16 samples of different brands of bagged milk obtained from some selected markets within Kaduna metropolis were analyzed for the occurrence of bacteria using pour plate method on selective media. The total aerobic count ranged from 4.0 x 103 to 2.8 x 106. The result obtained showed that bacteria (Staphylococcus aureus) in bagged milk ar...
ABSTRACTTwenty-two healthy albino mice were grouped into A, B, C, D, and E. Group A had six mice while groups B – E had four mice each. The mice were infected with Plasmodium berghei and the methanol extract of the leaves of Adansonia digitata was obtained by maceration extraction method. Phytochemical screening of the plant extract revealed the presence of alkaloids, flavonoids, saponins, carbohydrates and cardiac glycosides. The infected mice Group C, D and E were orally treated with the ...
ABSTRACTAccording to a few recent studies, calcium titanate is a material that is similar to hydroxyapatite in biological properties. However, calcium titanate is not currently being used in the biomedical application as to hydroxyapatite. The objective is to prepare nano calcium titanate powder from the solution of calcium oxide, ethanol, and titanium (IV) isopropoxide via sol-gel synthesis. The fiber size, pore size and morphology were studied by phenom scanning electron microscope (SEM). T...
ABSTRACTPhytoremediation, based on the theory of botanic tolerance and accumulation of certain pollutant, is a new developing ecological technique primarily used to clean polluted environment. Blastofiltration is applied to phytoremediation of heavy metal polluted water at present. The study used castor, okra, melon and moringa seeds as experimental materials to investigate their potentials as possible blastofiltration materials. The results showed that with the trial time lasting up to 72 ho...
