Response of Melon Cultivars to Natural Infection by Diseases in South Western Nigeria
I. A. Kehinde
International Journal of Biology , 2011, DOI: 10.5539/ijb.v3n4p47
Abstract: Melon is an important crop in South western, Nigeria. The study evaluated incidence and severity of Anthracnose, mildews, wilt, leaf spot and blight disease of melon cultivars: Serewe, Bara A, Bara B in cultivated plots in South Western Nigeria. Experiment was set in a randomized complete block design with five replicates in the Teaching and Research field of the University of Ibadan, Nigeria. Disease incidence and severity was varied among the melon cultivars. Predominant foliar diseases were Anthracnose and leaf blight with maximum disease incidence index of 82.0–100% across the cultivars. Disease incidence and severity indices for all diseases were high during the early season (27.0-100%) and low during the dry season (19.0-65.0%) except for the downy mildew disease. Fusarium wilt disease incidence was significantly lower than all other diseases encountered. Cultivars were not consistent in their reaction to the diseases and these also varied with the years. The study has given information on the predominant diseases for which control management technology should be developed.

American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.42047
Abstract: Seeds of 24 West African rice (Oryza sativa L.) genotypes were evaluated for seed vigour traits in the laboratory and field in two cropping seasons at the Research Farm of Federal University of Agriculture, Abeokuta, Nigeria. Seed yields of these genotypes were also determined in the field during the two seasons. Data collected on seed vigour traits were subjected to multivariate analysis including principal component analysis (PCA) and cluster analysis. The first three axes of the principal component analysis across the two seasons captured 86.34% of the total variation among the entries and identified seedling vigour index-I, seedling vigour index-II, speed of germination index, percentage germination, seedling establishment, emergence percentage and seed yield per plant as the characters contributing most to the variation. Cluster analysis classified these genotypes into four distinct groups based on germination and emergence percentages. Fifteen of the genotypes with mean values of between 60.43% and 65.18%, clustered in group 1, two genotypes each with mean values of 65.71% and 58.81% and 20.11% and 29.49% clustered in groups II and IV respectively while the remaining five genotypes with mean values of between 55.19% and 55.88% clustered in group III. Hybridization of genotypes across dusters could lead to increase in heterosis in cross progenies. Those characters identified by PCA could be included in the crop improvement programme for improved seed quality within West African low land rice germplasm.

African Journal of Biotechnology , 2002,
Abstract: The bio-deterioration of breadfruit in storage and its effects on the nutrient composition of the fruit was investigated at Ibadan, Southwestern Nigeria. Freshly dropped fruits were stored under laboratory conditions for a period of 9 days. Aspergillus niger, Rhizopus stolonifer, Botryodiplodia theobromae, Mycovellosiella fulva, Penicillium sp. and Aspergillus flavus, were found associated with deteriorating breadfruit in storage The freshly harvested breadfruit has 70.2% carbohydrate which reduced to 59.4% within 9 days of storage under room temperature. The amount of fat content, protein and the energy of the breadfruit also reduced in fruit samples stored for 9 days, while there was an increase in the moisture content, crude fibre, and ash content of the breadfruits in storage. The mineral contents also increased during the period of storage. (African Journal of Biotechnology: 2002 1(2): 57-60)
Rulers against Writers, Writers against Rulers: The Failed Promise of the Public Sphere in Postcolonial Nigerian Fiction
A Kehinde
Africa Development , 2010,
Abstract: Various literary critics have dwelt on the nature, tenets and trends of commitment in Nigeria literature. However, there is paucity of scholarly studies on the representations of the failed promise to the public sphere in postcolonial Nigerian fiction. This paper, therefore, examines the strategies and technicalities of representing the castrated hope of the public sphere in postcolonial Nigerian fiction, using the templates provided by Chinua Achebe’s Anthills of the Savannah, Ben Okri’s The Famished Road and Chimamanda Ngozi Adichie’s Purple Hibiscus. The methodology involves a close reading of the selected texts, using Jürgen Habermas’s concept of the Public Sphere as the theoretical framework. The paper reveals that the context of the texts (Nigeria) lacks the public sphere, which is supposed to provide a liminal space between the private realm of civil society and the family, as well as the sphere of public authority. This is disclosed in the refusal of the characters to disregard ‘status altogether’ (Habermas 1991:36).

Anemia , 2013, DOI: 10.1155/2013/254765
Abstract: Background. Iron status in patients with sickle cell anaemia is a matter of continuing investigation. Objective. This paper aims to determine the serum iron status of under-five, sickle cell anaemia patients. Methods. The study spanned from December 2009 to February 2010 at the Consultant Outpatient Clinics involving 97 HbSS subjects and 97 age- and sex-matched HbAA controls. Biochemical iron status was assayed in subjects and controls. Results. Age range of the children was seven months to five years, with a mean of 30.6 (±15.97) months. Irrespective of gender, mean serum iron values were higher in HbAA controls than their HbSS counterparts but the observed difference was not significant ( and 0.111, resp.). The mean total iron binding capacity values of males and females were also not significantly different for sickle cell anaemia subjects and controls ( ). Males and females with HbAA had significantly lower serum ferritin when compared with their HbSS counterparts. Irrespective of gender, mean transferrin saturation was lower in HbSS subjects but the difference was not statistically significant ( ). Conclusion. Children with sickle cell anaemia have higher serum ferritin than controls, implying relatively higher iron content in the reticuloendothelial cells. 1. Introduction Sickle cell anaemia contributes significantly to morbidity and mortality among children in sub-Saharan Africa. Much is known about the disease presentation and end organ manifestation but the iron status in children with Sickle cell anaemia is still a matter of controversy [1]. In children with sickle cell anaemia, chronic haemolysis results in increased availability of iron directly from lysed red cells and also from increased absorption of iron from the gastrointestinal tract [2]. Additionally, the high load of iron provided by multiple blood transfusions [3, 4] would suggest that iron deficiency is unlikely in sickle cell anaemia. However, in some parts of the world, the frequency of blood transfusion among patients is now less as a result of improved management in recent years [5]. Reduced frequency of transfusion implies a reduction in sources of iron and, therefore, increased vulnerability to iron deficiency anaemia. This assertion is buttressed by a study in the USA which suggested that iron deficiency was commoner than expected in untransfused children with sickle cell anaemia [6]. In addition, frequency and need for blood transfusion are not uniform for all children with sickle cell anaemia. Ferritin is a high-molecular-weight protein that contains approximately 20% iron

Journal of Xenobiotics , 2012, DOI: 10.4081/xeno.2012.e5
Abstract: Untreated detergent bearing wastes discharged into the environment are sources of linear alkylbenzene sulfonate (LAS). Detergent wastes usually do not contain nitrogen or contain very low amounts. Biostimulation by introducing limiting nutrient element can be useful in biotreatment of such waste. The effect of inorganic and organic nitrogen supplements on aerobic degradation of LAS by LAS-utilizing bacteria was examined. Phosphate-buffered LAS mineral media were prepared and supplemented with different nitrogen sources: NPK fertilizer (inorganic) and urea fertilizer (organic). Individual and various consortia of pure cultures of Alcaligenes odorans, Citrobacter diversus, Micrococcus luteus and Pseudomonas putida, previously isolated from a detergent effluent polluted stream, were used. Biodegradation of LAS was monitored in terms of half-life (t ) of the surfactant. The rates of biodegradation by the consortia can be ranked as: 4-membered (t =8-12 days) >3-membered (t =8-13 days) >2-membered consortia (t =10-15 days) >individuals (t =9-16 days). The inorganic nitrogen source enhanced utilization of the surfactant, while organic nitrogen supplementation generally slowed degradation of the surfactant. In undertaking biotreatment of detergent bearing effluent, inorganic nitrogen should be used as biostimulant.
Effect of additional carbon source on biodegradation of linear alkylbenzene sulfonate by las-utilizing bacteria

Journal of Xenobiotics , 2011, DOI: 10.4081/xeno.2011.e2
Abstract: Aerobic biodegradation of linear alkylbenzene sulfonate (LAS) by LAS-utilizing bacteria (LUB) in the presence of other sources of carbon (glucose and soluble starch) was examined. Biodegradation of LAS was monitored as primary degradation in terms of half-life (t ) of the surfactant. Biodegradation of LAS by the individual LUB was slower in the presence of Glucose. Biodegradation of the surfactant by the various consortia of LUB was slower in the presence of the carbon sources: t increased to 3 days. The rates of biodegradation by the consortia can be ranked as: four-membered (t =9 days) > three-membered (t =9 to 13 days) > two-membered consortia (t =10 to 15 days). Generally, degradation in the presence of the carbon sources was faster with the consortia than the individual species. Degradation of the surfactant by the LUB was generally fastest in the absence of additional carbon sources. The possible role of additional carbon sources in persistence of surfactant in water bodies and the application of the observation in management of LAS-containing-effluent is suggested.

Abstract: A wide divergence of opinion exists on the source and effect of conflicts on corporate productivity and the effectiveness of the various strategies available for managing them. It has been argued by some that conflicts are signs of a vibrant organization while others contend it is destructive and capable of retarding stability and profitability of organizations. Using a student t distribution to test the significance of response and purposive sampling technique to administer a self-design questionnaires to 50 respondents cutting across all cadres of staff of First Bank of Nigeria Plc.,(Lagos Branch), revealed that the main sources of conflict in the organization relate to perception and value problems. The specific issues bother on employee compensation and welfare while managers prefer the compromise, problem solving and dominating strategies to minimizing the incidence of organisational conflicts. Based on the findings of the study, it was recommended that strategies which promote industrial democracy should be chosen by management as the preferred option in dispute resolution. In addition, the ideal level of conflict resolution required to attain optimum performance for every organisation is unique and situational hence managers are duty bound to establish the best maintainable by the organisation.

Anti-Money Laundering Policy and its Effects on Bank Performance in Nigeria
Idowu, Abiola,Obasan, Kehinde A.
Business Intelligence Journal , 2012,
Abstract: This study seeks to review the role of anti-money laundering policy in Nigerian banking sector with its attendance effects on performance. Three banks in Lagos State (South Western Nigeria) were used for the study. The correlation result indicates the existence of a strong positive relationship between banks performance and adoption of sound money laundering policy with a value of 0.881. The coefficient of determination also show a value of 0.775, which implies that anti-money laundering policy actually explain and account for about 77.5% of the nature of banks performance in the economy. This result is due to the fact that banks do not need to serve as a channel for illicit monetary activities before they can post a meaningful performance in the industry. Hence, money laundering has negative consequences on the economy which include loss of revenue to the government, worsens criminal rate in the society, and threatens the political stability and internal security of a nation.
