- " Sand bodies deposited across normal growth faults and associated rollover anticlines are critical reservoirs for the accumulation of oil and gas. This paper addresses aspects of structures and depositional environments of some sand bodies within the Tomboy field, offshore western Niger Delta. Structural interpretation was undertaken to identify and assign faults found in the 3-D seismic volume. Time and depth structure maps in combination with well logs were used to produce for five horizons, namely: H1 to H5 and identify the depositional environments respectively. Two major growth faults (F4 and F7 which are normal, listric concave in nature), three antithetic (F1, F3 and F6) and two synthetic faults (F2 and F5) were identified. Structural closures identified as rollover anticlines, and displayed on the time/depth structure maps; suggest probable hydrocarbon accumulation at the downthrown side of the fault F4. Point bars, distributary channel and mouth bars, barrier island and tidal channels are the depositional environments. This study shows that the Tomboy field is made up of sand bodies deposited in different environments across normal, growth faults and associated rollover anticlinal structures. " 1 results 1
- "This study exploited the possibility of new fractal creation in order to increase drastically the stock number of handy fractal Images through the combination of limited base symmetric attractors' codes. The randomised play of 'chaos game' with the iterated function systems (lFS) comprising finite set of contractive affine maps coupled with simple coordinate transformation and linear superposition provide a framework for the new fractal image creation. However the fractal characterization that captures fractal image structural complexity and beauty was achieved by the implementation of optimum disk count algorithms. Comparison of the corresponding analytical and estimated fractal dimension of four symmetric base attractors are within the range of 3.2 and 7.1 percent absolute relative error. The correlation coefficient being R2=0.97. Aesthetically valuable symmetric fractal images were produced across various combinations explored with estimated fractal dimension 1.5329≤D≤ 1.8156 at transformation square window size of 2. Estimated fractal dimensions and magnitude were found to be independent of window size and number of base attractors' codes combined respectively. The findings of this study have potential applications in textile industries and general fashion design specializations. " 1 results 1
- A stuck' was carried out to determine the effect of a raw diatomaceous earth (DE) obtained fromBularafa community in Yobe State, Nigeria on the proximate composition of stored cowpea variety (IT96D-610K). Twelve small scale prototype silos made of two different structures (wooden and galvanised mild steel (GMS)) were constructed and used in the storage of the cowpea for a 4-month period. 7000g of cowpea at 9.88% moisture content admixed withdiatomaceous earth havingtwo different particle sizes(0.075mm and 0.090mm) and three different concentrations(0.1g, 0.05g and 0g of DE/100g of cowpea)in varying combinations were loaded into each silo. The sample admixed with zero concentration of diatomaceous earth served as the control in each of the wooden and galvanised steel structures respectively. Temperature, relative humidity and moisture content within the storage structures were monitored. Proximate compositionsuch as ash, crude protein, fat, crude fibre, carbohydrate alongside moisture content were also measured.Significant differences (p<0.05) was observed between the control sample and treated samples.The values of moisture content, ash content and crude fibre increased while crude protein, fat and carbohydrate decreased with increased storage period. At the last month of storage, wooden silo recorded a higher temperature value (28.88˚C) compared to the galvanised steel (GMS) silo which showed (22.30˚C). An increase in moisture content was observed in both silos with wooden silos showing a higher percentage rise in both control and treated samples. At the end of the fourth month the average moisture content, ash content, crude protein, fat, crude fibre and carbohydrate content of control and treated samples were(10.57% and 13.39%), (4.12% and 4.16%), (22.75% and 22.69%),(1.95% and 1.90%),(2.21% and 2.23%) and (57.75% and 55.63%) in the GMS and wooden silos respectively.Cowpea admixed with diatomaceous earth stored in GMS silo showed the best nutritional quality. Hence of all the storage materials, storage time, particle size and concentration of DE used galvanised mild steel (GMS), 0.075mm particle size and 0.05g of DE/100g of cowpea for the first four weeks of storage were seen to be the best. These proved to be the best method of storage for cowpea as the procedure retained its proximate composition. The increased crude fibre level in the treated samples is a major indicator for good health 1 results 1

- Adherence to current treatment guidelines on prescription of antimalarials by healthcare providers can promote better malarial treatment outcomes. However, adherence rate and factors influencing adherence to treatment guidelines have not been well explored. This study was carried out to assess adherence to current guidelines on prescription of antimalarials and associated factors among healthcare providers in Lokoja Local Government Area, Kogi State, Nigeria. The study was cross-sectional in design. A total of 404 healthcare providers aged 18-65 years were selected through proportional allocation from public health facilities and patent medicine stores. Using a semi-structured, interviewer-administered questionnaire, data were collected on socio-demographic characteristics of respondents, knowledge and training on current guidelines and prescription practice. Adherence was defined as correct prescription of artemisinin-based combination therapy for uncomplicated malaria in a child and adult. Knowledge of current guidelines was assessed on a 5-point scale and scores ≥3 were categorised as good knowledge while scores <3 were categorised as poor. Data were analysed using descriptive statistics, Chi-square test and logistic regression with significance level set at 0.05. Mean age of respondents was 36.9 years (SD = 9.2 years). Respondents comprised of nurses (36.6%), patent medicine vendors (30.0%), doctors (18.3%), community health extension workers (9.7%), pharmacists (3.2%) and community health officers (2.2%). Over half (53.0%) were males and about three-quarters (74.4%) were married. Half (50.0%) had good knowledge of the guidelines of which 34.2% were doctors and 4.0% each were community health officers and pharmacists. A total of 270 (66.8%) of respondents claimed they requested for confirmatory test before treatment of malaria. In all, 54.2% had been trained on the guidelines of which 36.1% were patent medicine vendors while only 1.4% was pharmacists. Overall adherence to guidelines on anti-malaria prescription was 39.6%. The adherence among doctors was 67.6%, community health officers (55.6%), pharmacists (19.8%). Respondents who were trained on the guidelines were twice more likely to adhere to guidelines. (AOR=2.28; CI=1.41-3.69) while respondents with good knowledge were four times more likely to adhere to guidelines compared to those with poor knowledge (AOR=3.99; CI=2.39-6.69). Knowledge of and adherence to current guidelines on antimalarials prescription was generally low in Lokoja among community health officers, nurses, pharmacists and patent medicine vendors in the study. Government should train these categories of health care providers to improve their knowledge and adherence to the guidelines.

- Adolescence is a transitional phase from childhood to adulthood during which significant changes in body composition occur with a tendency towards excessive fat accumulation. Determining body fat proportions at this stage of life could give an insight into the need for early intervention. The actual body fat estimates of school adolescents have not been adequately researched in Nigeria. This study was carried out to determine the Percentage Body Fat (PBF) of secondary school adolescents in Ibadan North Local Government Area, Nigeria. Using a three-stage random sampling method, 623 adolescents aged 10 to 19 years were selected from two private (141) and six public (482) secondary schools in a cross sectional study. A validated, structured interviewer-administered questionnaire was used to collect data on socio-demographic characteristics. Parents’ socioeconomic status was grouped as high, middle and low using the combination of level of education and occupation. The PBF was assessed using a Bioelectric Impedance Analyser (BIA). The participants’ PBF for age and sex were classified as low <5th, normal 5th – 95th and high >95th percentiles of the study population respectively. Data were analysed using descriptive statistics, Chi-square test, Student’s t-test, ANOVA and Pearson Correlation. Overall mean age was 14.5±2.1 years and 60.0% were female. The participants were from families in low (19.6%), middle (51.7%) and high (28.7%) socioeconomic categories. Overall, mean PBF was 12.6±7.1%. Mean PBF for male 8.5±5.6% was lower than 14.9±6.7% for female (p<0.05). There was no significant correlation between PBF and age among female (r = 0.064, p>0.05) but a significant negative correlation was observed among male participants (r = -0.224, p<0.05). Among male participants, mean PBF of low (7.8±5.2%), middle (8.3±5.5%) and high (9.2±6.1%) socioeconomic status were not significantly different (p>0.05). Similarly, there were no differences in the mean PBF of low (15.2±6.9%), middle (14.8±6.9%) and high (14.9±6.7%) socioeconomic status among female participants (p>0.05). Proportion of adolescent PBF <5th and >95th percentiles were 3.9% and 19.9% respectively. Prevalence of PBF >95th percentile was higher among male (28.1%) than female (14.4%) adolescents (p<0.05). Slightly more female participants (4.3%) than male (3.2%) had PBF <5th percentile (p<0.05). More male participants in public (31.8%) compared with 15.8% among those in private schools had PBF >95th percentile (p<0.05). There was no significant difference in prevalence of PBF >95th percentile among female participants in private (10.7%) compared with those in public schools (15.5%). There was no significant difference in the proportion of respondents who had PBF >95th percentile in low (20.5%), middle (22.4%) and high (15.1%). Similarly, proportions of participants with PBF <5th percentile in low, middle and high socioeconomic groups were 3.3%, 4.3% and 3.4% respectively were not significantly different. Male adolescents were likely to rise above 95th percentile of percentage body fat estimates for age and sex irrespective of socioeconomic status especially in public school. There is the need to initiate programmes that may enhance early identification of adolescents with the tendency of accumulating excess fat. 1 results 1
- Adolescents have one of the highest rates of suicidal behaviours found in research. Hence, health research and interventions have become a key preference among them. This study therefore, examined Depression And Suicidal Ideation And Moderating Effect of Suicide Resilience Among In-School Adolescents In Ibadan South East And Oluyole Local areas of Oyo state. The descriptive survey design was used for the study and a combination of random and purposive sampling techniques were employed to select 275 participants with age ranges between 15 and 19years, x =16.87, SD=1.02 into this study. A structured questionnaire focusing on socio-demographic profile, Depression, Suicide Resilience and Suicidal Ideation was administered to the participants. Five hypotheses were formulated, tested and all were confirmed. Data were analyzed using descriptive statistics, simple regression and independent sample for ttest, point-biserial correlation, biserial correlation multiple regression and hierarchical regression analysis. The results showed that Depression (R2= 0.061, F = 17.753, p<.01) significantly predicted suicidal ideation and behaviour, while gender had significant influence on suicide behavior (t (273) = -4.597, p<.01) among in-school adolescents. In addition t-test, point-biserial correlation results showed gender (rpb= .265, n=273, p= .01). accounted for 7% variance observed in the reported Suicidal behavior among in-school Adolescent. Age also had significant influence on suicide behavior (t (273) = -3.300, p<.01) among in-school adolescents. In addition t-test, biserial correlation results showed Age (rpb= -.175, n=273, p= .05). accounted for 3% variance observed in the reported Suicidal behavior among in-school Adolescent. Additionally, Suicide Resilience and Depression [F(2,272)= 11.74, R=.14, R2 =.02,p<.01] jointly predicted Suicide behavior (ΔR2 =0 .81, p < .001). Meanwhile, the effect of depression on suicidal ideation and behavior was moderated by the interaction between depression and suicide resilience (b = -.285, p < .05) Suicide Resilience can reduce the impact of Depression on suicidal Ideation and Behavior. It suggests that when suicide resilience was high, the association between depression and suicide behavior was the weakest; when suicide resilience was low, the association was the strongest. Additional clinical implications, limitations of the study, and suggestions for future research are addressed. 1 results 1

- Adult education programmes in both developed and developing nations usually include continuing education. The relationship between the two notions is that someone requires additional information, either inside or outside of school systems, in order to remain relevant wherever one is at any given time. The information, communication, and technology era brought in a knowledge economy that should normally support continuing education, nevertheless there are still obstructions that prevent people from learning. Although these hurdles are both personal and structural, there seems be no justification for anyone to remain without information for the purpose of individual and group survival. Continuing education and knowledge economy are two concepts that have become popular in educational theory and practice but they are not combined as related concepts in literature. This is an attempt to clarify the concepts for both professional and practicing adult educators generally in African countries and particularly in Nigeria where policy documents for the practice of adult education sometimes deviate from the extant principles and theories. This paper used a conceptual analysis of terms and a systematic review of the available literature. It concludes that continuing education and the knowledge economy necessitate more access to learning that takes into account individual needs and requirements from organisations. This is as a result of the increased availability and application of knowledge in positively changing human conditions. 1 results 1
