An overview of the impact of arab civilizaton on yoruba culture in Nigeria
(The Yoruba Studies Association of Nigeria (YSAN) c/o Department of Linguistics and African Languages University of Ibadan, 2023-01) Akewula, A. O.; Kamorudeen, B. K.
Nigeria was a land where idol worship marked the religious life of the inhabitants. With the advent of Islam which came with its civilization, Nigerians’ faith, rituals, rites, practices and customs changed and impacted the Nigerian culture. Invariably, the contact of the Arabs with the people of Yorubaland in Nigeria brought about a new era in their beliefs. The Arabs who were mainly Muslims and with the focus to spread Islam preached assiduously against the syncretic religious practices of the Yoruba in the Southwestern region of Nigeria. There is no gainsaying the fact that every religion has its own unique identity characterized by traditions, values and norms that make it stand out. Over the centuries, we have observed that the southwestern Nigeria culture is gradually fading away as we adopt Arab civilization and this persists as days go by. The Arab civilization has influenced the Yoruba culture in different domains. Some of the impacts are noticeable in our education, language, borrowing, social activities, entertainment, traditional settings, marriage, naming, burial and funeral rites and widowhood. This paper employs historical method which attempts to examine how Arab civilization influenced Yoruba culture in the aforementioned domains including religion and devotional rites. It is our hope that some aspects of Yoruba Culture that are not inimical to Islamic teachings would be preserved to avoid becoming moribund.
` Knowledge and perceptions of marital rape among women in Oyo State, Nigeria.
(Ibadan Biomedical Communications Group, 2020) Ogunwale, A. O.; Dipeolu, I. O.; Olaitan, O. L.
Marital rape is a serious public health problem affecting many women worldwide. In Nigeria, there is dearth of evidence-based information on issues relating to knowledge and perceptions of marital rape among women. This study was therefore designed to assess the knowledge and perceptions about marital rape among married women in Oyo State, Nigeria. The cross-sectional survey was conducted among 1200 women aged 18-60 years who were ever-married. Participants were recruited using a multi-stage random sampling technique. A validated semi-structured questionnaire which contained a-8 point knowledge of health consequences of marital rape and a-20 point marital rape perception scales was used for data collection. Data were analyzed using descriptive statistics and Chi-square test. Respondents’ mean age was 36.6 ± 9.6 years, while their husbands’ mean age was 42.1 ± 10.3 years. Mean knowledge score was 3.9±2.2 and 23.4% had poor knowledge of marital rape. Respondents who had poor knowledge who were aged ≤24 years, 25–49 years and ≥50 years were 31.6%, 25.3% and 9.6%, respectively (P≤0.05). Mean perception score was 8.9 ± 3.6, and 69.8% had supportive perceptions relating to marital rape. A higher proportion of respondents with marriage duration of >20 years (84.6%) had marital rape supportive perception compared with those with marriage duration of 0-10 years (64.9%) (P≤0.05). Knowledge of marital rape remains inadequate, especially among younger women. Furthermore, many women had supportive perceptions for marital rape, a situation which can adversely hinder adopting appropriate preventive behaviours. Multiple community-based health educational interventions have potentials for addressing the phenomenon.
"Assessment of physical and chemical characteristics, heavy metals composition in Awba Dam: Contamination levels in sediment, soil, Amaranthus hybridus (L.) and effluents from different drains in University of Ibadan
(Ecological Society of Nigeria, 2023) Ajibola, F. O.; Fayinminnu, O. O.
"The indiscriminate use of heavy metal-compounded fertilisers and pesticides as well as
the release of raw and ill-treated domestic wastewater into water courses poses threats to
living organisms in the environment. This study therefore, evaluated the physical and
chemical properties and heavy metals contamination levels in water and sediments of
Awba dam, University of Ibadan with a view to assessing its quality and suitability for
irrigation. Water samples from Upstream, Midstream and Downstream of Awba Dam and
three drains containing outflows from areas with anthropogenic activities and solid
sediment samples were collected from Awba Dam, while vegetable and soil samples
were collected from a nearby farm (200 m away) from the dam. Samples were analysed
for physical and chemical parameters (pH, Dissolved Oxygen (DO), Biochemical and
Chemical Oxygen Demand (BOD, COD)], nitrate and phosphate), and heavy metals (Cd,
Cr, Co, Ni and Pb) in the water, sediment, Amaranthus hybridus and soil were
determined using standard methods. Data obtained were analysed using ANOVA at
p<0.05. Results revealed DO having highest value (3.77 mg/L) at Tech and maximum
values of BOD (14.67 mg/L) and COD (57.06 mg/L) were obtained at upstream and these
were above the WHO limits. Highest nitrate level (36.45 mg/L) was at Tech and lowest
(20.44 mg/L) at downstream. Similarly, phosphate value in all locations ranged from
0.09-0.61 mg/L. All heavy metal levels were in non- detectable quantities in water and
Amaranthus hybridus. In sediment, Cr and Co had highest values of 13.67 and 5.33
mg/kg, respectively at upstream and Ni had 12350 mg/kg at midstream, all above the
USEPA Sediment Criteria. Also, Ni had the highest value (18811.00 mg/kg) in soil. The
chemical oxygen demand in water as well as nickel concentrations in both sediments
from Awba Dam and soil were high. Therefore, there is need for regular monitoring of
these parameters is recommended."
Toxicity and Residue of Mexican mint (Plectranthus amboinicus Lour.) essential oil as a bio-insecticide on cowpea beetle (Callosobruchus maculatus Fabricius)
(Ecological Society of Nigeria, 2023) Fayinminnu, O.O.; Akeem, B. A.; Isienyi, N. C.; Alabi, O. Y.
"Cowpea (Vigna unguiculata L.) (Walp)) is one of the legumes grown worldwide due to its high value in
protein. However, the crop faces insects` attack from the field to storage especially Callosobruchus
maculatus (cowpea grain beetle) which has brought huge economic losses in storage. Insect pests of
cowpea had been controlled with various synthetic insecticides but with hazardous effects on human
health and the environment. This study assessed plant essential oil which could be used as an alternative
to control stored cowpea grains beetles. Therefore, the objectives of this study were: To identify the
compounds present in Mexican mint as a bio-insecticide, to determine the residue of the Mexican mint
essential oil in treated cowpea grains and to determine the proximate analysis of treated cowpea grains.
The study was conducted at Entomology Research Laboratory Department of Crop Protection and
Environmental Biology, University of Ibadan using a susceptible cowpea variety Ife Brown cowpea
grains. Six treatments: 0.75, 1.25, 1.75 and 2.25 mL/g of Mexican mint essential oil, Phostoxin (0.01g
recommended) and without treatment (control) were replicated four times and laid out in a completely
randomized design. The essential oil extraction, the essential oil residue in cowpea grains and proximate
analysis were determined using standard procedures. Data were collected on mortality of insects corrected
with Abbott’s formula and analysed using ANOVA at p<0.05. Results revealed 26 compounds with two
prominent compounds identified; monoterpenes (0.22-6.16%) and terpenes (0.28-4.16%). Toxicity of
Mexican mint essential oil concentrations on C. maculatus gave a 93.75% mortality rate at 1.25, 1.75 and
2.25 mL/g, respectively which compared favorably with phostoxin (100%), while the control gave highly
significant reduction of 12.50%. Compounds found in the cowpea grains residues showed no trace of
toxicity which were: alpha. -Pinene (144.98-346.79 mg/L); tau. -Muurolol and Linalool (0.22-0.54mg/L),
Di- epi-1,10-cubenol (15.38mg/L) and alpha.-Cadinol (0.35mg/L), respectively from 1.25, 1.75 and 2.25
mL/g. Proximate analysis of treated cowpea grains revealed essential oil at 0.75 mL/g having highest
value of 29.75% in crude protein, highest (91.00%) dry matter was obtained from 2.25 mL/g, similar
values of 10.75 and 11.14% moisture content was recorded from 0.75 and 1.25mL/g, respectively.
Highest similar values ranging from 54.16-54.56% of carbohydrate were obtained from 1.25, 1.75 and
2.25 mL/g, respectively. This study revealed that Mexican mint essential oil at 1.25, 1.75 and 2.25 mL/g
contained important insecticidal components, which enhanced high toxicity on Callosobruchus maculatus
on stored cowpea grains, with no toxic residue of the essential oil in the cowpea grains and no harmful
effects on the nutritional components. Therefore, Mexican mint essential oil could give food quality and
safety when used as a bio- insecticide to protect cowpea grains in storage.
