Risk Factors That Influence Criminal Victimisation
Get PDFThis study aims to identify the risk factors that influence criminal victimisation and endeavour to manage the recognised risk factors to control and prevent criminal manipulation or reduce the likely impact characteristics. If it can be well determined with sufficient specificity that people with specific characteristics are more prone than others to become crime victims and that such crimes are bound to occur at particular spots than others, attempts to control and prevent such crimes could be more helpful. That way, individuals would be made to understand when the crime risks are most pronounced. According to lifestyle exposure theory, the crime risk is influenced by functional opportunities for crime, local environments and associated exposure to criminal threats in society. Based on situational crime prevention theory, this study aims to determine why the offender's decisions to commit a crime are influenced more by the immediate situation than by considering possible detection and punishment. Authorities have not adequately recognised their rights and needs as victims of those harms. This study adopted a cross-sectional survey design. This method lets the scholar get data from several sets of populations simultaneously. In this study, the focus is on reducing victimisation through improving individual personal security. Towards this end, the researcher examined the role played by particular persons in victimisation. The study examined these relationships using samples of common area residents (n = 210), key informants (n = 45) and 145 members of focused group discussions. The findings of this research are expected to provide data that helps inform the policymakers and the individuals who are the primary victims of criminal victimisation of the need for enhanced personal security to assist in crime risk management. Researchers investigated Kajiado County, located on the southern side of Nairobi, the capital of Kenya
The Role of Bacterial Plasmids in the Biodegradation of Low-Density Polyethylene in Mitigating Climate Change
Get PDFPolyethene causes pollution and global warming not only because of the increase in the problem of waste disposal and landfilling but also because it releases carbon(iv)oxide and dioxins due to burning, which hurts the climate. Recent studies have shown that biodegradation using plasmid prosessing bacteria (PPB) could help prevent environmental damage from pollution and reduce carbon footprint and greenhouse gas emissions from polyethene usage. This study assayed the low-density polyethylene degrading potential of PPB assayed from polyethylene-polluted sites. Soil samples and waste sachet water bags, popularly called 'pure water', were collected from a polyethene dumpsite near Ekiti State University. These samples were analysed for bacterial loads and polyethene degrading PPB using nutrient agar and mineral salt medium, respectively.The biodegradation of low-density polyethene using sachet water films was observed spectrophotometrically using the broth culture of the bacterial isolates for 30 days on a mineral salt medium. The bacteria were identified based on molecular characterisation using 16S RNA sequencing. Six bacterial isolates identified from polyethene polluted sites include: Lysinibacillus xylanilyticus strain BN-13 (S6), Rhodopseudomonas palustris strain KRPR02 (W5), Pseudomonasaeruginosa strain JAY (N2), Stenotrophomonas maltophilia strain T7D7, Pseudomonas aeruginosa strain SMVIT-1 (S1) and Achromobacter xylosoxidans YEB (W11), and four isolates were observed to have the presence of plasmid after analysis.The four isolates were used to degrade the PE films, which peaked at degradation on the 21 days, followed by a gradual declination on the 28 days. L. xylanilyticus strain BN-13(S6) exhibited the highest degradation of 0.898 nm, and A. xylosoxidans strain YEB (W11) exhibited a minor degradation of 0.788 nm. The result revealed that PPBs are competent biodegrades of polyethene wastes and can be used as a better approach to restoring polyethene and mitigating climate change
Spectroscopic Analyses of Alkaloids and Tannins from the Leaves of Ficus Citrifolia
Get PDFFicus citrifolia (Family Morracae) is known for numerous medicinal uses, including antibacterial, anti-inflammatory, analgesic, and anti-cancer. Alkaloids and tannins were isolated from crude extracts of the leaves of Ficus citrifolia and analysed using GCMS, FTIR and HPLC. From the ethanol, 2000 mL and 80 % methanol, 1500 mL extracts, alkaloids and tannins were isolated, respectively. Thin layer and column chromatography (TLC and CC, respectively) were employed to isolate and purify alkaloids and tannins. The ethanol (2000 mL) extract gave 22 fractions, and 20 fractions were collected from the 80 % methanol (1500 mL) extract of F. citrifolia. Fractions with similar retention factor (Rf) values were pooled and identified as AK1 to AK3 for alkaloids and TA1 and TA2 for tannins. The spectra of the Fourier Transform Infrared (FTIR) Spectroscopy for AK1 to AK3 showed characteristic absorption peaks between 3370 and 3470 cm-1, of NH and NH2, 1168 and 1233 cm-1, C-N stretching vibrations, 726 and 895 cm-1, C-H aromatic out of plane bending vibrations, all of which are expected absorption peaks for alkaloids. TA1 to TA2 showed characteristic absorption peaks between 3300.1 and 3400.1 cm-1, OH stretch of phenols, 1077 and 1084 cm-1, C-O stretch of alcohols, 1457.1 and 1461.1 cm-1, C-C stretch (in ring) aromatic, all of which are expected absorption peaks for tannins. The Gas Chromatography-Mass Spectroscopy (GC-MS) of AK3 identified the fraction as 1,2-Benzoisothiazole-3-amine TBDMS derivative. High-Performance Liquid Chromatography (HPLC) of TA1 and TA2 treated under the same condition with a tannin standard, quercetin, showed that both fractions were quercetin. Hence, alkaloids and tannins were successfully isolated from the leaves of F. citrifolia. The presence of these compounds corroborates the medicinal uses of the plant

Suitability of Lateritic Soil in Oluku Community, South-South, Nigeria As a Borrowed Pit Material For Construction Purposes
Get PDFLaterite is a highly weathered material rich in secondary iron and aluminium oxides, which is of great use in road and building construction. This material is found in a larger quantity in the Oluku community; however, there is no prior knowledge of the geotechnical properties and suitability of the lateritic soils for construction purposes. This study investigates the suitability of the lateritic soil from the Oluku community as a borrow pit material for construction purposes. Soil samples were collected from 5 different pits within the study area and at different depths of 1.3, 1.4, 1.2, 1.3 and 1.5 m, respectively, by hand auger. Laboratory tests such as particle size distribution analysis, specific gravity, Atterberg limits, compaction test and California Bearing Ratio (CBR) test were conducted on the soil samples by BS 1377.The particle size distribution test results revealed that the percentage passing of the soil samples ranged from 31.62 to 67.60%, indicating poor materials. The specific gravity results ranged from 2.3-2.8, while the compaction test results revealed that the optimum moisture content (OMC) and maximum dry density (MDD) ranged from 8.10-15.70% and 0.70 Mg/m³-2.04 Mg/m³ respectively. The consistency limits results show that liquid Limit, Plastic Limit and plastic index ranged from 19.73 to 28.52%, 11.89 to 19.03% and 6.70 to 9.82%, respectively. The soaked and un-soaked CBR values ranged from 2.24-4.37 % and 10.35% to 22.65% respectively. These results were compared to the specifications established by the Federal Government of Nigeria for roads and bridges (1997) and British Standards Methods of Test for Soil for Civil Engineering Purposes (BS 1377: 1990). Overall, the result revealed noticeable deviations from standards due to the presence of a high content of silty clay. This implies that the soil samples present at the Oluku community are not unsuitable as borrow pit material and, therefore, cannot be used for construction
