Managing Innovative University Education for the Attainment of Sustainable Development Goals in Nigeria

Abstract: Sustainable development goals (SDGs) have become widespread as several countries have embraced them. The aim of this paper is to examine how innovative Nigerian university education can be achieved for sustainable development in Nigeria. Thus, the paper focuses on SDG 9 which is the goal of industry, innovation, and infrastructure. The world today is a digitalised world characterised by digital technology and infrastructure and it is necessary for 21st-century students to keep up with these modern-day digital practices. SDGs have been set up by the United Nations to improve the living standards of the people in the world despite differences in class, religion, economy, race, and other factors that usually cause division between people. These sustainable development goals can be achieved through university education which is known for imparting knowledge, values and discipline to students and shaping them to become future leaders. The roles of Nigerian universities in achieving innovative university education for sustainable development as well as the challenges impeding the advancement of innovative university education in Nigerian universities, were examined to include lack of technological knowledge, inadequate funding, inadequate e-learning, and ICT facilities, amongst others. It was concluded that there is a need for Nigerian universities to develop innovative infrastructure so as to achieve sustainable development in Nigerian universities, as this will enable students to compete with their peers globally. The way forward to these issues would be adequate funding, provision and proper maintenance of e-learning and internet facilities, and proper management of resources, amongst others.

Characterisation of Saw Dust Ash – Quarry Dust Bituminous Concrete

Abstract: This study evaluates usefulness of Quarry Dust and Saw Dust Ashas mineral fillers in a bituminous concrete in order to reduce cost and encourage reuse of waste materials in the environment. Bituminous concrete blends were generated with 4% Quarry Dust and 4% Saw Dust Ash replacements of aggregates. The binder contents were 3, 3.5, 4, 4.5 and 5% for a 60/70 penetration grade bituminous binder. Briquette specimens were formed using the five different bituminous concrete blends. Standard laboratory experiments were conducted on the aggregates, Quarry Dust, Saw Dust Ash, bituminous binder and bituminous concrete specimens based on the relevant codes and standards. The Marshall method was used for the bituminous concrete design procedure. The optimum binder content was found to be 4.88% using the standard Marshall curves. At optimum binder content, using 4% design air void for medium traffic and maximum aggregate of 10mm, the Stability, Flow, VMA and VFA were 8.15kN, 8.28(0.25mm), 15.22% and 74.2% respectively. These were found to have passed the Asphalt Institute design criteria.

Numerical Simulation of Diffusion Rate of Crude Oil Particles into Wave Passes Water Regime

Abstract: Numerical models were developed to simulate the diffusion rate of crude oil particles in to wave passes water regime. developed models were used t o correlate the diffusion rate as a function of the physical properties of the crude oil sample, wave dimensions and diffusion coefficient. The models were simulated with the aid of Hewlett Packard HP-85 computer and found that the diffusion rate was principally influenced by the crude oil density and wave phase differences. The correlated models are useful in predicting extent of crude oil diffusion as a result of oil spillage.

Invivo Impact of Malaria and HIV Co-Infection on CD4 Cell Count of Infected Patients of Niger Delta Extraction

Abstract: The study evaluated the impact of co-infection of malaria parasitaemia, and HIV positive indices on the CD4 cell count of 120 HIV infected subjects, who were already diagnosed and visiting Braithwaite Memorial Specialist Hospital Port Harcourt for routine Medical check-up. Also, a control group of 40 HIV negative were included as part of the study control group. The subjects were between the age ranges of ≤10–79 years respectively. A double check laboratory assay was conducted to detect the presence of antibody to HIV as confirmed using immunocomb 11 and Determine for HIV status. A thick Blood film stained with field stain (A and B) was used to detect the presence of malaria parasite in the subject’s blood. Furthermore, CD4 cell count was assayed using Partec cyflow counter (Partec, Germany). Excel and Graphpad statistical software were used for analysis of the data generated. The result among the HIV positive subjects and control subjects revealed that the highest positive for malaria infection was observed among ≤10 years age group as 2 (100%) and 11 (84.61%) respectively. In the HIV positive subjects, the distribution of malaria infection among sex revealed a high rate in male 42(77.78%) than in female 44 (66.67%). Similarly, the control recorded a high rate of malaria infection in male 11 (57.89%) than in female 7 (33.33%). However, 86 (71.67%) had malaria and HIV co-infection while 34 (65%) had only HIV mono infection. The positive HIV subjects who had CD4 cells count below 200 cells/mm3 were 15%, above 200-499cells/mm3 were 58.3% while 500 cells/mm3 and above had normal CD4 cells counts for 26%. Nonetheless, for the control subjects, no CD4 cells count of below 200cells/ mm was observed, 2.5% fell within the moderate category while 75% had normal CD4 cells count. Statistical analysis using ANOVA and t-test showed that there is significant difference between CD4 of seropositive and seronegative subjects infected with or without malaria (p=0.00). In addition, a t-test further demonstrated Comparison of Mean CD4 Cell Count among HIV and Malaria Infected and Non-Infected Subjects. MP/HIV Co-Infection and Mono Infection with No Infection showed strong mean difference (p=0.00) in the various CD4 counts while HIV Mono-Infection and others only had a non significant (p=0.44) mean difference between HIV Mono-Infection and No HIV or Malaria Infection. A robust and effective malaria and HIV control management programme should be strongly underpinned; so as to improve the quality of life of patients and HIV patients should be encouraged to live a healthy life style, through the provision of antiretroviral drugs and regular health education engagement, even as the provision of antimalarial treated net would be helpful to the subjects.
