Cadmium, chromium, iron, zinc, and copper levels of flaked paints collected from fifty buildings of four major cities – Enugu, Onitsha, Aba, and Port Harcourt in Eastern Nigeria were studied. Fifty samples of the flaked paints were ground with laboratory pestle and mortar, 2 g of fine ground paints that could pass through a 0.5-mm sieve were digested with 15 ml concentrated nitric acid and perchloric acid at a ratio of 1:1 and analyzed for cadmium, chromium, iron, zinc and copper using atomic absorption spectrophotometer 500. Cadmium ranged from 9.032 ± 0.000 to 10.575± 0.000 and 6.845 ± 0.000 to 10.028 ± 0.002 mg/kg in Enugu and Onitsha, respectively. In Aba and Port Harcourt, the levels of cadmium ranged 7.464 ± 0.002–9.343 ± 0.002 and 7.293 ± 0.002–9.395 ± 0.000 mg/kg, respectively. Chromium levels were significantly lower in Enugu (range 0.940 ± 0.000–12.793 ± 0.002 mg/kg) when compared with the values from other cities namely Onitsha (range 1.613 ± 0.002–15.140 ± 0.000 mg/kg), Aba (range 15.206 ± 0.000–39.215 ± 0.000 mg/kg) and Port Harcourt (range 33.118 ± 0.002–55.418 ± 0.002 mg/kg). The highest levels (mg/kg) of iron (11 908.150 ± 0.000), zinc (31.508 ± 0.002) and copper (7.588 ± 0.002) were seen in buildings from Enugu aged 11 years and above. The iron level (mg/kg) ranged from 1391.750 ± 0.000 to 10 476.845 ± 0.000, 1450.176 ± 0.000 to 11 580.750 ± 0.000 and 3314.913 ± 0.002 to 8162.333 ± 0.002 in Onitsha, Aba, and Port Harcourt, respectively. Zinc levels were significantly lower in Onitsha than in Aba and Port Harcourt. Age of building did not seem to affect the levels of these metals namely iron, zinc and copper from these cities. This study shows that flaked paints increase the environmental heavy metal burden in Nigeria.

The study focused on comparison on impact of HIV/AIDS patient’s characteristics on their blood pressure in Nigeria: a case of NAUTH, COOUTH and Onitsha general hospital in Anambra State. The blood pressure being the response variables are systolic blood pressure & diastolic blood pressure, while the predictor variables being the HIV/AIDS patient’s characteristics are age, baseline count, initial weight, present weight and CD4 count of HIV/AIDS patients. The R software package was employed to facilitate the data analysis. The Multivariate Regression Model of the two response variables (Systolic PB and Diastolic PB) was first fitted with the coefficient of determination of 31.88% and 46.80% respectively for NAUTH data, 27.9% and 37.98% respectively for COOUTH data and 97.35% and 57.15% respectively for general hospital, Onitsha data. The test on the significance of the parameters for the multivariate regression for NAUTH data revealed that age and baseline count of HIV/AIDS patients have significant relationship with systolic BP at 5% level of significance, whereas other predictor variables (initial weight, present weight and CD4 count of HIV/AIDS patients) are not significant, while in the second model, only age has a significant relationship with diastolic BP, whereas initial weight, present weight, baseline count and CD4 count of HIV/AIDS patients do not have significant relationship with diastolic BP at 5% level of significance. The test on the significance of the parameters for the multivariate regression also revealed that only age has significant relationship with systolic and diastolic BP at 5% level of significance, whereas other predictor variables are not significant for both COOUTH and general hospital Onitsha data. It was further revealed that the data collected from the general hospital Onitsha has the highest coefficient of determination (0.9735) with the lowest AIC (1348.944), BIC (1374.462) and residual standard error (2.587) for systolic blood pressure model which makes the data used in this study the most suitable for the model employed under the stipulated year of study. Also observed that the same data collected from the general hospital Onitsha has the highest coefficient of determination (0.5715) with the lowest AIC (1825.917), BIC (1851.435) and residual standard error (6.008) for diastolic blood pressure model which equally makes the data used in this study the most suitable. It is clear from the result obtained in this study that the data set collected from general hospital, Onitsha from 2003 to 2017 is most appropriate for the multivariate multiple linear regression models.

This study examines Onitsha personal names (OPN) from a morphosyntactic perspective. The major objective of this study is to examine the syntactic and morphological structure of some OPN. Specifically, the study seeks to ascertain the morphological processes and the relation in the internal structures of the morpheme that are combined to form the names. A sample of 250 names for both male and female were used for the analysis. The data were obtained from a list of names in schools, men and women religious associations. Oral interviews were conducted with native speakers in order to get clarifications as it concerns the meaning of the names. The roots, stems, and affixes of the names were analysed using the descriptive approach and applying the word formation rules. The findings reveal the following: that most of the morphological processes in the formation of OPN are predominantly clipping, prefixing and suffixing in a hierarchical manner, such that the meaning of the names are predictable from their structural components and most of these names are derived from clauses by desententialisation process; the philosophy behind the names are often lost due to clipping; OPN at sentential level can function as statements, interrogatives, or imperatives, commands; the morphological components in terms of size, length or shape can be monomorphemic, dimorphemic, trimorphemic and polymorphemic. Structurally, they can be single stem, compound or complex.
