ABSTRACT Particulate Matter (PM) are suspended solid and liquid particles in the atmosphere, classified into coarse (PM10, 2.5 to 10µm) and fine (PM2.5 2.5 µm) and irregular in shape with very few being regular and fine (Fe>Al>Na>Mg>Si>Zn>Cu>Mo>Mn>Ba>Ti>Pb>Ni>La. The IA showed highest average concentration of all elements in the PM10 except Ba, which was highest in TA. The elemental composition agreed with the mineralogical data as revealed by the PCA. Factor 1 was loaded with Al, Si, Ca, ...
ABSTRACT This paper analysed policy correlates of agricultural production and agricultural production sustainability outcomes in Ghana and Nigeria. It underscores the influence of political systems and international development agendas as correlates of agricultural production and agricultural production sustainability outcomes. This is to the extent of providing evidence policy on agricultural production and agricultural production sustainability outcomes. Ghana and Nigeria have comparable fa...
ABSTRACT An Enzyme Linked Immunosorbent Assay (ELISA), employing a recombinant peptide capture antigen (R32tet32) was used to detect antibodies against the circumsporozoite protein (CSP) of the malaria parasite, Plasmodium falciparum in 169 serum samples from 16 subjects from two villages, Afefu (FA) and Tobalogbo (TB), in Igbo-Ora Community of Oyo State, over a period of 12 months. The maximum and mean Ab response for FA was higher than for TB samples (0.511 AU±0.170, 0.124±0.045U and 0.2...
ABSTRACT Contamination of petroleum products in groundwater in Baruwa community, Lagos has been widely reported, as a result of ageing pipelines and vandalisation. Information on the types, nature of hydrocarbon and other contaminants that could assist in assessing the level of contamination is lacking. This study was therefore designed to assess the hydrogeochemical settings (delineate aquiferous units, quantify contaminated unit and define types of hydrocarbon present) in the groundwater r...
The interest of this thesis is in finding out whether or not there is any residential relocation in the old core of Ibadan city within the past five years (1968-1972): and if there is any, to find out the processes generating the movements. Consequently there are two main parts to the study. out the processes generating the movements. Consequently The first part sought for the pattern and volume of residential relocation. It looked at the direction and distance of the movements, using an acco...
ABSTRACT The hydrocarbon potential and paleodepositional environment of Cretaceous sediments from the Borno Basin, Nigeria, were assessed by Rock-eval pyrolysis and biomarker geochemistry. The Total Organic Carbon (TOC), soluble organic matter (SOM) and genetic potential (GP) values ranged from 0.52 – 0.82wt%, 455.64 – 1003.04 ppm and 0.23 – 0.63 mg/g, respectively. These values suggested that the sediments were moderately rich in organic matter. The Hydrogen Index (HI) values (19 – 8...
ABSTRACT Herbal medications are becoming increasingly popular but a most-extraordinary claim by traditional/herbal medical practitioners relates to a Gram-positive bacterium, Staphylococcus, which has been depicted as a deadly sexually transmitted disease that manifest in the form of worms and other symptoms; with contributory roles including infertility, sexual dysfunction and impotency. They further boasted that they are the only ones that possessed the remedy (herbal) for the Staphylococcu...
ABSTRACT This study provides information on the infectivity rate of Plasmodium falciparum on subjects attending University of Ilorin Teaching Hospital (UITH), Ilorin, Kwara State, Nigeria. Information on the use of certain preventive measures to control malaria transmission and also the need to keep a clean environment for more healthy living is given. A total of 200 subjects attending UITH were recruited into the study. Their blood samples were collected and analyzed microscopically for the ...
ABSTRACT The phytochemical contents of some milled Nigerian softwood chips were carried out in a quest to evaluate their potentials as sources of alternative medicine as well as uses in other industrial applications. The qualitative and quantitative analysis were ascertained. Tannin was found in all the Nigerian softwoods examined with the highest quantities obtained in Sterculia oblonga (1240 mg/100 g) and Barteria nigritiana (1230 mg/100 g). Highest quantities of alkaloid were obtained in C...
Abstract: The synthesis and characterization of new complex monoaza and pentaaza angular phenothiazine derivatives is reported. The first derivative, 6,10-dichloro-17-azadibenzo[a,n]triphenodithiazin-5,11-dione 10 was obtained by a basecatalyzed reaction of 2,6-diaminopyridine-3,5-dithiol 5 and 2,3-dichloro-1,4-naphthaquinone 9, while the second derivative, 7,9,15,17-tetraamino-6,8,16,18,25-pentazadibenzo[a,n]di([1,4]benzothaizino[3,2-c,l])triphenodiathizine 11 was obtained by the reaction o...
ABSTRACT Cymbopogon citratus, commonly known as lemongrass due to its lemon fragrance when crushed. Due to the presence of many phytochemicals in lemongrass, their use in the treatment of illnesses has increased. The antimicrobial activity of Cymbopogoncitratus (Lemongrass) was evaluated on Pseudomonas aeruginosa, Salmonella typhi, Streptococcus pyogenes and Candida albicans. The extract was obtained using two solvents; ethanol and methanol. The antimicrobial activity of the extracts was test...
ABSTRACT Airports require complete safety initiatives with a maximum of 20 minutes response time to distress situation. They are therefore regulated by International Civil Aviation Organisation (ICAO) standards. However, in Nigeria, airport safety and distress response have been of great concern due to inadequate infrastructure. This study, therefore, examined safety facilities and response capability to distress situations in Nigeria international airports. The effects of haphazard spatial ...
ABSTRACT A sequence stratigraphic approach was applied to K-Field, within the western Niger Delta by integrating wireline logs of four wells; 001,003, 004 and 005; and high resolution biostratigraphic data of wells 001, 004 and well 005. The study is aimed at deducing key bounding surfaces, depositional sequences and their corresponding systems tracts as well as the palaeodepositional environment of the hydrocarbon bearing Agbada Formation in the study area. Two sequence boundaries at 8900 ft...
ABSTRACT Subsurface samples from Kinasar-1 well, in the Bornu basin, northeastern Nigeria, were studied to deduce the lithofacies distribution, provenance, palaeodepositional environment and paleotectonic conditions of the basin. In addition, the hydrocarbon potential of the associated shales has been highlighted. The lithological sequence comprised a basal unit of over 1300m coarse grained sandstone of the Bima Formation, overlain by 1200m shaly unit with a sandy base, belonging to the Gongi...
Vitamin C and Coronavirus: Not a Vaccine; Just a Humble Cure Commentary by William F. Simmons and Robert G. Smith, PhD During the pneumonia epidemic in North Carolina in the 1940's, after American soldiers returned from the war in Europe, a small-town physician used an anti-infective protocol of intravenous vitamin C to cure 42 cases of viral pneumonia. [1] During the same period, the physician used a similar treatment to cure 60 cases of viral poliomyelitis. All patients were clinicall...
