Abstract :

This study examined sustainable international financial flows. The study specifically examined the effect of foreign direct investment inflows, foreign direct investment outflows, remittance inflows and remittance outflows on the development of Nigeria economy. Panel Least Square Regression analysis was used to analyse the secondary data collected for the study and also to test the four null hypotheses formulated for the study. Durbin Watson Statistics (DW) test was also used to test the presence of autocorrelation in the models of the study. The findings reveal that all the independent variables, namely, foreign direct investment inflow, foreign direct investment outflow, remittance inflow and remittance outflow positively and significantly affect Gross Domestic Product of Nigeria. Based on these findings, it was recommended that The Nigerian government should encourage the inflows of foreign direct investment and contact policy institutions that can ensure the transparency of the operations of foreign companies within the economy, Government should ensure that remittance inflows accruable to Nigeria is properly managed to the development of Nigeria economy. Nigerian government should equally budget for remittance outflow as it helps in reduction of poverty.

Abstract :

Objective: To identify the types of ophthalmological diagnoses, preferred low vision devices, demographic profile of clients utilizing low vision services atEye Clinic of University of Port Harcourt Teaching Hospital (UPTH) from 2013 to 2018. Methodology: A retrospective review of 6 years clinical records from the low vision clinic of UPTH - 2013 to 2018. Data extraction: Data on biodata of patients, ocular pathologies and patients’ preferred low vision deviceswere obtained from the eye clinic out-patient register and entered into Microsoft Excel sheet using a template comprising of the ophthalmological diagnosis and year of diagnosis. Data analysis: Data from Microsoft Excel sheet were exported to SPSS version 25 for statistical analysis. Line graph was used to express trends in demographic profiles, ophthalmological diagnoses and preferred low vision devices. The absolute number of patients across the time period was presented in tables and figures. Trend analysis was performed using Chi square for trend statistics and statistical significance set at p≤0.5. Results: Patients in 41 – 50 age group showed a more step wise consistency in accessing our services. The trend in the utilization of low vision services among urban and rural dwellers had a step-wise increasing pattern in both instances. Glaucoma, oculocutaneous albinism were the most common cause of low vision. The preferred low vision aids were telescope and spectacle magnifiers.Conclusion:The trend of the utilization of low vision services in UPTH through a period of six years was undulating with improvement among rural dwellers and female folks.

Abstract :

Two derivatives of benzo-hetreocyclic ligands (3H-Benzooxazole-2,2-dithiol and 3H-Benzothiazole-2,2-dithiol) were synthesized by refluxing one mole of 2-Amino-phenol with one mole of carbon disulphide (CS2) in acetone, then one mole of 2-Amino-benzene-thiol and one mole of carbon disulphide (CS2) in acetone for two hours respectively. The mixture were allowed to cool and then evaporated at room temperature, to afford a solid creamy precipitates which were washed with hexane, filtered, air dried and recrystallized with a mixture of acetone and hexane. The final product were filtered and allowed to dry. Infrared spectroscopy (IR) was used to confirm the functional groups associated with the ligands. The ability of the synthesized ligands to remove heavy metals (Fe, Cu, Zn and Ni) ions from aqueous solutions was investigated. This was carried out at five different pH values to monitor its effect on heavy metal removal. The metal salts and the synthesized ligands were dissolved in the same solvent (ethanol) and a ligand-metal ratio of 1:1 used in the investigation. The 3H-Benzooxazole-2,2-dithiol ligand, was observed to exhibit highest percentage metal removal efficiency for Nickel at pH value  3.00 giving the 90.76% removal. The 3H-Benzothiazole-2,2-dithiol exhibited the highest removal efficiency for zinc at pH 11.00, giving a percentage of 95.64%. (11.0) Though both ligands were effective in metal removal, the 3H-Benzothiazole-2,2-dithiol ligand showed better percentage removal efficiencies (67.96% - 95.64%).
