    INVESTIGATION INTO EXTENT OF COMPLIANCE WITH AUTOMOBILE WASTE MANAGEMENT AND DISPOSAL REGULATIONS IN FEDERAL CAPITAL TERRITORY, ABUJA AND NIGER STATE, NIGERIA
    (Department of Environmental Resource Management, Nasarawa State University, Keffi., 2017-07-01) Gazali, S.A; Ohize, EJ.; Salami, K. A; Idris, A.M.
    This study was designed to investigate the extent of compliance with automobile waste management and disposal regulations in Federal Capital Territory, Abuja and Niger State, Nigeria. The study answered two research questions and tested two null hypotheses at .05 level of significance. A sequential explanatory mixed method design was used for the study and a total of885 copies of the questionnaire were completely filled by automobile mechanics, automobile users and technical staff of environmental agencies and were used for the analysis using IBM SPSS Statistics version 20. Mean and standard deviations were used for the research questions, while independent sample t-test and ANOVA was used to test the hypotheses. Turkey HSD was also used as Post Hoc test for the rejected hypothesis. The research questions were ranked for the purpose of assessing the relative priorities. Some of the findings of the study revealed that: state environmental agencies are not monitoring the activities of automobile mechanics, automobile mechanics and automobile users are not storing oily absorbents and grease according to environmental regulations and are not trained in emergency preparedness against chemical hazard, rules and regulations governing automobile waste collection and disposal are not effectively enforced in the state, automobile waste generated are rarely in compliance with environmental regulations.

    Phytochemical and Antibacterial Activities of Vitellaria paradoxa Stem Bark and Root Extracts against Some Clinical Isolates of Respiratory Tract Infections
    (Department of Plant Science and Biotechnology, Nasarawa State University Keffi, 2020-12-11) Namadina, M.M.; Idris, A.M.; Sunusi, U.; Abdulrazak, M.H.; Musa, F.M.; Olaogun, O.N.; Aminu, M.A.; Yakubu, N.; Muhammad, Hassan Sani; Et et.
    Respiratory tract infections continue to be the most frequent and important cause of short term illnesses that compel an individual to seek medical attention both in developing and developed world. It is typically the first infection to occur after birth. Many bacterial species have been reported to develop resistance to antibiotics commonly prescribed for respiratory tract infections. Therefore, the need to search for natural products for remedy of this problem cannot be overemphasized. The methanol and aqueous extracts of Vitellaria paradoxa stem bark and root was carried out using cold maceration extraction method. Phytochemical screening was carried out using the standard methods. Agar well diffusion, agar dilution and spread plate methods were employed to determine the zone of inhibition, minimum inhibitory concentration, minimum bactericidal concentration and rate of kill respectively. The two extracts showed broad spectrum of activity but the aqueous extract had larger zones of inhibition ranging from 17 mm – 23 mm and lower M.I.C and M.B.C values ranging from 6.25 mg/ml – 12.5 mg/ml. Phytochemical screening of methanol and aqueous extracts of Vitellaria paradoxa stem bark and root showed the presence of phenol, alkaloid, saponins, tannins, steroids, triterpenes, flavonoids and carbohydrate as secondary metabolites. This study has justified the traditional use of Vitellaria paradoxa stem bark and root in the treatment of respiratory tract infection caused by bacteria
