Background: African contribution to global research output is said to be low. Poor funding and poor skills in grant writing havebeen suggested as important factors for this situation.
Objectives: Applications for research ethics clearance in a hospital were reviewed to have an overview of the planned studiesand the proportion of them that attracted national and international funding.
Methods: A review of all applications for ethical clearance received by the institutional review board of a university teachinghospital at Ile-Ife, Nigeria, from 2016 to 2020. They were analysed according to study nature, scope, purpose, and sponsorshipusing descriptive statistics presented as frequency tables and charts.
Results: A total of 878 applications were reviewed. There were 803 (91.5%) applications for local, 45 (5.1%) for national multicentre,and 30 (3.4%) for international multicentre studies. Applications for medical fellowship were 352 (40.0%) while 208(23.8%) were from academic staff for non-degree research. There were 610 (69.5%) applications for self-sponsored studies.Only 18 (2.0%) and 26 (3.0%) received sponsorship from national and international donor agencies, respectively.
Conclusions: Local studies formed the bulk of the submissions for ethics clearance. National and international donor fundingof research is abysmally low in this Nigerian tertiary institution studied.

Background: This study was aimed at evaluating the microbial quality and proximate analysis of soymilk produced and soldwithin Calabar Metropolis.
Methodology: Soymilk samples were purchased in pairs from five locations in Calabar Metropolis. The samples collected weresubjected to microbiological and proximate analysis to ascertain the hygienic standards of the products and nutrient contents.
Results: The result showed that the highest heterotrophic bacterial count of 5.3 × 105 cfu/ml was recorded in soymilk samplesold in Goldie market while the least (2.7 × 104 cfu/ml) was recorded at Watt market. The mean fungal count was highest inAkim market samples (5.8 x 104 cfu/ml) and lowest in Atimbo market samples (2.4 x 103 cfu/ml). The probable bacterial andfungal isolates were identified as: Pseudomonas aeruginosa, Bacillus sp, Escherichia coli, Klebsiella sp, Salmonella sp, Streptococcus sp,Staphylococcus aureus, Aspergillus sp, Rhizopus sp, Penicillium sp and Mucor sp. All the isolated bacteria species were found to be resistant to more than 50% of the antibiotics used. Proximate composition analysis of the soymilk samples revealed high moisture,carbohydrate and protein contents.
Conclusion: The microbial population detected in terms of number and types reflected poor hygienic standard of production.
Keywords: Soymilk; contamination; public health; hygiene; foodborne illnesses.

Authors: Behrens van Tonder Carin , Joubert Gina , Moodley Anand 
Published: October 2023

Background: Restless legs syndrome (RLS) occurs in patients with chronic renal failure (CRF).
Objectives: To determine the prevalence and morbidity of RLS in CRF patients on dialysis.
Methods: This cross-sectional questionnaire-based study included 100 dialysis patients (50 on haemodialysis [HD]; 50 on peritonealdialysis [PD]). A focused lower limb examination was done. Patients were classified with RLS when reporting uncomfortablefeelings in their legs that improved with movement and worsened when resting and at night.
Results: Gender distribution was equal. The median age was 43 (19–67) years. Six patients (HD and PD n=3 each) had internationalcriteria-confirmed RLS. Twenty-four patients reported symptoms suggestive of RLS. Fourteen and 16 patients with RLSsymptoms were on HD and PD, respectively. Sleep disturbances occurred in 43.3% (n=13) of patients with RLS symptoms,compared to 20.0% (n=20) of the large cohort. Sleep disturbances, peripheral sensory loss, chronic disease-related anaemia,increased urea and decreased albumin levels were more common among patients with RLS symptoms.
Conclusion: RLS symptoms occurred in 30.0% of the entire cohort, although only 6.0% met the international criteria. The typeof dialysis had no impact on the incidence of symptoms. Identifying RLS in patients with CRF on dialysis will allow for earlyintervention.
Keywords: Restless legs syndrome; chronic renal failure; haemodialysis; peritoneal dialysis; symptoms.

Published: October 2023

Background: Chronic low back pain is a common musculoskeletal symptom affecting the lower part of the spine. It is described as pain and discomfort around the lumbar region lasting for more than twelve weeks. The symptoms of chronic low back pain might range from a dull ache to a stubbing or shooting sensation. This nature of pain may be localized around the axial region or radiate to the lower limbs affecting the patients’ daily activities. The aim of this study, therefore, was to evaluate vertebral changes in the lumbar spine of adults presenting with chronic low back pain at Kakamega County General and Referral Hospital.
Methods: This was a cross-sectional quantitative descriptive study whereby; patients’ data was collected during patients’ presentation at orthopedic outpatient clinic and MRI department. Purposive sampling of lumbar spine Magnetic resonance imaging scans was used to obtain data. A total of 144 patients were selected using the Yamane Taro formula. Anatomical vertebral changes of the lumbar spine were assessed from the selected MRIs to evaluate the structural causes of chronic low back pain. Descriptive statistics such as frequency and percentage were used in analyzing the data.
Results: It was noted that osteophytes were the most pathological changes causing chronic low back pain while fractures were the least common. Osteophytic changes in the vertebra and desiccation of the intervertebral discs can predispose one to chronic lower back pain.
Conclusion: The study recommends early screening and treatment of lower back pain to avert its sequelae.

Published: October 2023

The excess parameters associated with liquid mixes of acetonitrile-dimethyl sulphoxide were analyzed to estimate the degree of intermolecular interactions in the binary system. The viscosities and densities of the binary system were determined at temperatures of 298.15, 303.15, 318.15, 328.15, and 338.15K, respectively, with a percentage composition of 0 to 100 percent. Using the experimental density and viscosity measurements, the excess molar volumes (VmE), excess viscosity (nE), excess Gibbs' free energy of activation of viscous flow (G*E), and Grunberg-Nissan interaction parameters were calculated. Deviations from these parameters studied in the composition of the mixtures and temperature were discussed in terms of molecular interactions in these mixtures. A comparison of several interaction characteristics was expressed to better understand the intermolecular interactions between acetonitrile and dimethyl sulphoxide. As the temperature of the system and the mole fractions of acetonitrile rise, the viscosity and density of the experimental values drop. According to the findings, the excess parameters were mostly negative, indicating that dipoledipole interactions predominated in the acetonitrile-dimethyl sulphoxide solvent mixture.

Published: October 2023

This paper presents a stochastic modeling of wind speed over sixteen (16) Northern states in Nigeria using thirty-seven years (1984-2020) wind speed real time data. A Markov Chain Model was developed for the monthly wind speed state across study locations. In order to obtain the Markov chain transitional probabilities, the wind speed data was categories into various states using the Beaufort wind scale. It was observed that only the first four description of wind speed state A, B, C and D exist in the study locations. Uniform random states were also formed by generating uniform random number. The comparison of monthly simulated and actual wind speed state clearly shows that the model simulated over six months correctly across study locations except Niger. Given a current wind speed state conditions, the stochastic models available in this paper can be adapted to generate future wind speed state condition. The understanding of wind speed state helps in wind turbine design and selection of wind farm sites for wind energy generation.

Published: October 2023

This study compared the extrapolation strengths of two models: Autoregressive Integrated Moving Average (ARIMA) and Autoregressive Integrated Moving Average with an Exogenous Variable (ARIMAX) in the forecast of Nigeria's electricity consumption. Annual data on power generation and consumption from the Central Bank of Nigeria statistical bulletin for 2006 and 2016 over a 51-year period (1970-2020) was used. Industrial and residential electricity consumptions were examined for possible unit roots (non-stationarity) using the Augmented Dickey-Fuller test approach. The ADF test result showed that the time series achieved a stationary state for the variables under consideration at first difference. Akaike Information Criterion (AIC) and Root Mean Square Error (RMSE) were used to assess the performance of each models. Comparing the ARIMA and ARIMAX forecast models, ARIMA(0, 1, 1) emerged for modelling and forecasting industrial electricity consumption in Nigeria while ARIMAX (1, 1, 1) with installation capacity as exogenous variable was suitable for modelling and forecasting residential electricity consumption in Nigeria. The study recommended that for optimal residential electricity consumption in Nigeria, installation capacity and the total power generation in Nigeria should be enhanced.

Moi-moi is a steamed bean paste usually made from cowpea paste blended with seasonings and other ingredients. This study was carried out to evaluate the functional, chemical and sensory properties of moi-moi produced from cowpea and sprouted pigeon pea flour blends. Flours were produced from cowpea and sprouted pigeon pea and blended in the ratios of 100:0, 95:5, 90:10, 85:15, 80:20 and 50:50, where 100% cowpea served as the reference sample. The functional properties of the composite flours, proximate, mineral, and sensory characteristics of the moi-moi were evaluated. Functional properties ranged from 0.67 to 0.69 g/ml for bulk density, 1.33 to 1.70 ml/g for swelling index, 1.80 to 2.03 g/g for water absorption capacity, 1.27 to 1.73 for oil absorption capacity, 40.17 to 46.57 % for emulsion capacity and 30.30 to 34.00 % for foam capacity. Proximate composition results revealed that crude protein, crude fibre, and ash increased while moisture, fat and carbohydrate decreased with increased substitution of cowpea with sprouted pigeon pea. Mineral contents increased with increasing level of sprouted pigeon pea addition with values ranging from 26.30-63.37 mg/100g, 39.00-51.50 mg/100g, 272.00 to330.27 mg/100 g, 14.10 to 43.90 mg/100 g and 413.33-434.13 mg/100g for calcium, magnesium, potassium, sodium and phosphorous respectively. Sensory analysis revealed that moi-moi produced from 90% cowpea and 10% sprouted pigeon pea flour possessed the best organoleptic properties among the test samples. This study has demonstrated the production potential and nutritional benefits of sprouted pigeon pea complementation in the production moi-moi from cowpea.

Published: October 2023

The chemical properties of limestone have been the subject of several studies in recent years, highlighting its importance in various industrial applications. The present study focuses on six limestone samples from three geographical regions in Nigeria (Ashaka, Mfamosing, and Nkalagu). The analyses of their chemical composition using the Loss on Ignition Test and X-Ray Fluorescence Spectrometry was successfully carried out. Results of the study show that CaO is the main component, comprising between 60.054 % and 78.632 % of the samples. Values of Loss of Ignition (LOI) ranged from 30.820 % to 33.280 % while SiO2 composition ranged between 5.095 % to 12.238 %. Other oxides detected, include Al2O3 and Fe2O3, which make up less than 1 % of the composition. Obtained values were compared to Limestone standards for various industries and findings indicate that the Ashaka, Mfamosing, and Nkalagu limestone samples are of high purity and suitable for use in various industrial fields, including the steel industry, manufacture of bleaching powder, manufacture of calcium carbide, sugar industry, textile manufacture, cement industry, agricultural practice (soil liming), and flue gas desulphurization. Thus limestone deposits from Ashaka, Mfamosing, and Nkalagu has more potential and application uses beyond cement production which they are currently used for

Published: October 2023

Condensation of H-Indole-2,3-dione with Hydrazinecarbothioamide produced a Schiff base (2Z)-2-(2-Hydroxy-3H-indol-3- ylidinehydrzinE- 1-Carbothioamide. Cobalt(II) and Nickel(II) complexes, were prepared by the interaction of the metal(II) salts with the synthesized Schiff base. The prepared compounds were analysed by magnetic susceptibility, molar conductance, FTIR, AAS, solubility absorbance and empirical formula. The complexes showed moderate values of decomposition temperatures. Infrared spectral data of the Schiff base and the complexes, indicated coordination of the Schiff base to the metal(II) ions via azomethine nitrogen, indole oxygen and thione sulphur. The effective magnetic moment of the complexes suggested an octahedral geometry. The molar conductivities indicated a non- electrolytic nature of these complexes. The results of the absorbance and the empirical formula showed that, the Schiff base is monobasic and tridentate in nature towards the metal ions. Both the ligand and the complexes were screened for antimicrobial activity against Staphylococcus aureus, Salmonella typhimurium, Escherichia coli (bacteria); Aspergillus flavus, Aspergillus fumigatus and Mucor (indicus species) (fungi). Amoxicillin and Ketoconazole were used as positive control for the bacteria and fungi isolates respectively. The results showed that the complexes are more active than the free ligand but less active when compared with the standards.

Published: October 2023

During the dry season, dust particles on photovoltaic modules (PV modules) are a regular occurrence in Calabar, Cross River State. This dusty condition or environment is caused by the migration of dust particles from the Sahara region via the east-west wind. The concentration of dust on PV modules has an impact on the overall performance of solar energy systems. This research looks into the effect of dust particles on the output power of solar modules. This investigation was carried out by subjecting 80-watt monocrystalline PV modules to an outdoor experiment and analyzing the changes in current and voltage from the control and dusty PV modules with a digital multimeter. Other environmental factors such as relative humidity, ambient temperature, and solar radiation were also measured with a hygrometer, thermometer, and solar power meter respectively. Appropriate formulars were employed to calculate output power and efficiency. Dust particles on the surface of PV modules dramatically reduces the quantity of sunlight that penetrate the panel by 21.10%, resulting in a drop in the system's overall output power. The study emphasizes on the importance of frequent cleaning and maintenance of PV systems.
Blending Eclecticism and Specificity: The Art of Nollywood Epic Film Costumes
Authors: Okadigwe Mary Nkechi 
Published: October 2023

This research explores the unique approach to costume design in Nollywood, the Nigerian film industry. It focuses specifically on the epic film genre and discusses how Nollywood costume designers blend a variety of cultural and historical influences to create costumes that are both authentic and visually striking. It argues that this approach to costume design reflects the eclecticism and diversity of Nigerian culture while also highlighting the specificity and hybridity of the ethnic costumes represented in the film. Drawing on a close analysis of costume designs in Fred Amata’s Ijele (1999) and Kingsley Orji’s Eyes on the Throne (2019), the article offers insights into the creative processes and cultural context that inform this distinctive style of costume design. It uses the cultural hybridity theory by Bhabha Homi to explore the unique approach to costume design in films. Ultimately, the article demonstrates the importance of costume design in Nollywood epic films and argues that it plays a crucial role in constructing the visual and narrative world of these films
