Abstract: The acid activation of  bentonite clay ( at 1M concentration) was carried out using four different organic acids namely: propanoic acid (pka=4.88), lactic acid (pka=3.86), citric acid (pka=3.31) and oxalic acid (pka=1.25). Characterization was done using fourier transformed infrared analysis, x-ray diffraction analysis, adsorption capacity determination, and forster swelling factor. X-ray diffractogram shows the increase in  the basal spacing in the order: UMB = 15.743Å; PAMB = 16.265Å; CAMB = 18.217Å; OAMB = 19.062Å.  Oxalic acid displayed the highest adsorption capacity for xylene at 0.613, CAMB = 0.519, LAMB = 0.379, and lastly UMB = 0.051. The same trend was also seen in the swelling ability for xylene as OAMB = 1.2/2.0, CAMB = 1.0/1.8, LAMB = 1.0/ 1.6, PAMB = 0.2/0.4 and UMB = 0.0/0.0 being before agitation and after agitation values. The reduction in the pka value from PAMB to OAMB is observed to greatly influence the efficiency of adsorption. This is an indication that the pka of an acid is an important factor to be considered in the selection of adsorbent modifiers used in the treatment of petrochemical waste. This reduces the amount of pollutants that get into the environment from petrochemical effluents.

Abstract: This study aims at the assessment of heavy metals (Fe, Pb, Cd, Cr, Zn, Ni, As, and V), TPH and PAHs in soils from K-Dere artisanal refining site and Nwinua mangrove forest Kono (control site), Ogoni Rivers State. Hydrocarbons were analysed with gas chromatography; heavy metals were analysed using AAS. The study showed that there were spatial, temporal and significantly statistical variations (P<0.05) of TPH, total PAHs and heavy metals between study areas. Concentration of TPH peaked at 250,602mg/kg was found in intertidal soil sample where artisanal refining activities are carried out against 78.00mg/kg found in the control site in Kono. These values are well above EGASPIN target value of 1mgkg-1 in soil. The observed concentration of PAHs at the study areas varied both temporally and spatially in the soil samples analysed. The maximum mean PAHs concentration (68.85 ± 53.59mgkg^-1) and the lowest mean (8.50 ± 7.15mgkg^-1) was recorded in August and September 2018 at the artisanal refining site while the highest mean (21.99mgkg^-1) were recorded in May 2019 at the control site. These values are far higher than the Department of Petroleum Resources (DPR, 2002) target value for PAHs in soil 1mgkg-1 and also higher than the limit set by World Health Organization (WHO) (0.1mg/kg), thus raising concern of human exposure to cancer through food chain. High levels of heavy metals Fe (219 – 13, 234mgkg^-1), Pb (2.66 ± 0.39 – 3.15 ± 0.45mgkg^-1), Cr (BDL – 89.21mgkg^-1), Zn (23.00 – 111.10mgkg^-1), Cd (7.25 ± 1.11 – 8.06 ± 1.21mgkg^-1) were observed in soil samples from the artisanal refining site. These values are all indicators of pollution, and environmental degradation. Therefore, it is recommended that crops should not be planted at areas proximate to artisanal refining site as this may have effect on human through food chain. It is also recommended that artisanal refining activities in the area should be discouraged to avoid further contamination in the area.

Keywords: Soil, artisanal refinery, heavy metals, PAHs and TPH.

Abstract: Jatropha (curcas) seeds were collected from the Abuja campus of the University of Port Harcourt and the rubber seeds were purchased from Etche near Port Harcourt. The seed extracts were screened by determining their fatty acid profile using GC-FID. It was found that the concentration of both acids were high. The oleic acid in jatropha was 48.57mg/kg and linolenic acid was 36.30mg/kg being the highest in both oils. Thus these oils can be used in the production of oil paint. The two oils were used in formulating two different paints. Then a performance test was carried out on them to ascertain their suitability. The test showed that the formulated paints had good drying times and adhesion. Therefore, they can be used for the production of oil paint.

Abstract: The study focused on influence of collaborative teaching method on academic achievement of English Language students in secondary schools in Ondo West Local Government Area of Ondo State, Nigeria. Descriptive survey research design was used. The population for the study comprised, students and teachers in secondary schools in Ondo West Local Government Area of Ondo State, Nigeria. The sample size of the study was One hundred students (100) and one hundred teachers (100), making the total sample size of Two hundred (200) respondents. The respondents were selected through a proportional random sampling technique. The instrument used to collect data was self-developed structured questionnaire by the researcher, entitled “Questionnaire on Influence of Collaborative Teaching Methods and Academic Achievement in Secondary Schools in Ondo West Local Government Area of Ondo State, Nigeria”. The instrument was validated by an expert in Test and measurement, while its reliability, was done through test retest method and 0.66 coefficient reliability, obtained. Findings of the study revealed that teaching method could influence positively students’ academic performance. Recommendations were made that; teachers should be adopting teaching method in relation to the subject-matter taught; teachers should endeavor to use teaching method that can sustain learners’ interest in teaching-learning process.

Keywords: Collaborative, Teaching, Method, Academic achievement.

Abstract: Lamandau Regency/City is included in the category of cities with half-society half-culture.  Theory of cultural configuration has a very large role in urban spatial planning. Urban spatial planning in this study is based on the socio-cultural categories of the community. The research focuses on the spatial layout of traditional culture at the Lamandau Regency/City level which will be developed into a supporting area for traditional tourism and eco-tourism. Especially its unique traditional cultural works can be a tourist attraction for Lamandau Regency in particular, and Central Kalimantan Province in general. Qualitative methods are used to obtain a special picture of the understanding of the space of Lamandau City and the culture of the Dayak Tomun Tribe who inhabit it. Some of the things that the research has noticed are: (1) The spatial layout of Lamandau City which is still in the pattern of a developing city; (2) Cultural mapping that is constrained due to road access conditions; (3) Adjustment of the policies of the Lamandau Regency Government to the research plan – including the Object of Cultural Promotion. The results of the research are in the form of spatial planning for local communities, traditional communities, tourism supporting facilities as living traditions. The hope is that Lamandau culture can provide a multiplier effect to the community, stakeholders, and other parties who invest in tourism.

Keywords: Dayak Tomun tribe, culture, sacred, profane, tourism.
