The mental health of maternal caregivers of children with cerebral palsy in rural, low-income parts of Southern Africa
Authors: Ngokwana Rachamose , Clare Harvey 
Published: October 2024

Maternal primary caregivers of children living with cerebral palsy (CP) bear a significant burden that has the potential to impact their mental health. There is a paucity of research on the mental health of maternal caregivers of children with CP in rural areas of Southern Africa, highlighting the need for further exploration in this area. Specifically, there is a need to explore the multifaceted factors that influence the mental health of maternal primary caregivers of children with CP living in rural, low-income areas. The paper aimed to identify the various factors that influence the mental health of maternal primary caregivers of children living with CP who reside in rural, low-income areas of Southern Africa. Additionally, the paper sought to enhance the understanding of healthcare practitioners and stakeholders engaged in the care and support of these maternal primary caregivers and their children living with CP, therefore increasing awareness of this issue. This is a theoretical paper discussing the existing literature on the mental health of maternal caregivers of children living with CP in Southern Africa. The review was conducted by searching for published and grey literature in Google Scholar, PubMed, and EBSCOhost. The mental health of such caregivers is influenced by several factors, including the economic situation, physical demands, environmental conditions, insufficient information, experiences of stigma and marginalisation, interpersonal relationships, and emotional challenges. The social-ecological model is used to make sense of these factors in the mental health of maternal primary caregivers of children living with CP.

Authors: Ndanusa Adamu , Adamu Abdul , Madu Baba 
Published: October 2024

The study examined the effect of private sector investment on economic growth in the liberalised Nigerian economy 1990 to 2021. The data for this were analysed using descriptive and analytical tools. The study employed Auto-regressive distribution lags model (ARDL) estimation technique based on the unit root test to determine the effect of four major factors; Loan and Advances (LA), Interest rate (INTR) Exchange rate (EXR) and Inflation rate (INFR) on real gross domestic product (RGDP) which proxies economic growth. Findings revealed that there is negative and significant impact of Interest rate (INTR) Exchange rate (EXR) and Inflation rate (INFR) on economic growth in Nigeria. The study thus concludes that, by improving and strengthening private sector investment, economic growth would be enhanced in Nigeria. The study therefore recommends that in order to boost economic growth in Nigeria more emphasis should be placed on encouraging private investment through domestic and foreign financing.
Power Quality Disturbance Monitoring in PV Integrated Power System with Mode Decomposition and Ensemble Extreme Learning Machine
Authors: Choudhury A.R. , Mallick R.K. , Agrawal R. , Nayak P. 
Published: October 2024

Power quality disturbance (PQD) monitoring has become an important issue in modern power system due to integration of several renewable energy sources such as photovoltaic (PV), wind energy system (WES), Fuel cells etc. This research presents a mode decomposed based ensemble extreme learning machine (EELM) to recognise and classify the PQD events with higher accuracy in terms of rapid learning speed and smaller computational burden in a complete PV based power system, The PQD signals are decomposed using a variational mode decomposition (VMD) to obtain effective band limited intrinsic mode functions (BIIMF) which leads to compute robust features and improves classification accuracy. For Power Quality Disturbances detection and classification, an ensemble extreme learning machine is suggested since an ensemble outperforms any single contributing model in terms of performance and prediction. The proposed VMD-EELM approach is validated in a modified IEEE 13 Bus system integrating PV with eleven types of PQDs. The proposed research having 100% classification accuracy for no noise and 99.88%, 99.94% 99.94% for 20dB, 30dB and 40dB noises respectively. It is being demonstrated that the suggested method can reliably identify and track PQD occurrences both with and without noise.

Published: October 2024

Noise suppression in speech signal has received great attention in signal processing research community. However, existing methods of noise suppression such as the time-domain Kalman filter suffers from the psychoacoustic and physiological characteristic feature while the spectral subtraction technique performed in the modulation domain is associated with remnant noise in the enhanced speech signal. Therefore, in this paper, a Modulation-Domain coupled Kalman-Spectral Filtering (MD-KSF) in a single channel system is proposed to address the aforementioned shortcomings in the two existing techniques. The simulation of the proposed coupled MD-KSF was performed in MATLAB software environment. The evaluation of the proposed coupled MD-KSF technique in terms of Spectral waveform, Mean Square Error (MSE) and Log Spectral Distance (LSD) was performed. Furthermore, Perceptual Evaluation of Speech Quality (PESQ) and Short-Time Objective Intelligibility (STOI) tests were employed to validate the quality and intelligibility of the proposed coupled MD- KSF using the NOIZEUS corpus data set. The proposed technique shows significant noise suppression over the existing techniques.

Published: October 2024

Exposure to high concentrations of Polychlorinated Biphenyl (PCBs) has negative impacts on human wellbeing and the climate. This study determined the concentration, sources and health risks of PCBs in selected beauty shops in Ilorin, Kwara state. Air samples from fourteen beauty salons were taken using Solvent-Impregnated Polyurethane Foam (SIP-PUF) passive samplers for 30 days. The concentration of PCBs was determined with Gas Chromatography-Mass Spectrometry (GC–MS) operated in a Selected Ionization Mode (SIM). The health risk assessment of the PCBs was estimated using the Toxicity Equivalence Quotient (TEQ), Incremental Life Cancer Risk (ILCR), and Hazard Quotient (HQ) prescribed by United State Environmental Protection Agency (USEPA). The Positive Matrix Factorization (PMF) method was used in the source apportionment study. The average concentration of the PCBs ranged from 0.11–3.32 µg/m3 . The average TEQs for the PCBs in the beauty salon ambient air ranged between 2.96 × 10−1 - 9.30 × 10−1 ng WHO-TEQ/m3 . ILCRs and HQs estimated for the beauty shops considered were lower than 10-6 and 1 (USEPA set limit) for both adults and children. Eight factors were identified to be associated with the PCB sources; the most predominant sources are combined paint and pigment and mixed sources, which accounted for 20.08 and 28.91% of the total PCBs, respectively.

Published: October 2024

The reliability of a ball mill is crucial for the seamless operation of ore processing and other industrial plants, where unexpected equipment failure or downtime can result in significant financial losses and reduced production efficiency. Thus, this paper examined a hybrid method for identifying critical failure modes in a ball mill using the Failure Modes, Effects, and Criticality Analysis combined with the Complex Proportional Assessment with Grey Numbers (COPRAS-G). The COPRAS-G method was employed to assess the criticality of various failure modes by determining the weights of significant failure modes in the bearing, gearbox, motor, and shaft components of a ball mill. It was observed that gear seal failure is the most critical failure with percentage contribution (Ni) of 100%, while bearing wear is the least critical failure with percentage contribution (Ni) of 62%. The result suggests that failure modes of gear seal failure, gear pitting, motor bearing fatigue, and shaft fracture are regarded as the main contributors to failure with percentage contribution (Ni) of 100%, 97%, 87% and 83% respectively. Current ball mill maintenance includes corrective, preventive and predictive maintenance. For failure modes with high criticality, predictive maintenance was advised, while for moderate and low criticality, corrective and preventive maintenance were advised.

Food security remains a critical global challenge, necessitating the exploration of sustainable and nutrient-rich food alternatives such as edible insects. This study investigated and optimized the effect of treatment methods (boiling, ultrasound, and a combined boiling and ultrasound treatment) on Cirina butyrospermi and extrusion temperature (70℃, 80℃ and 90℃) on some quality (crude protein, in-vitro protein digestibility, calcium, zinc, iron, cooking time, water uptake ratio, lightness, and colour change) of rice pasta. The effect of treatment methods on Cirina butyrospermi powder and extrusion temperature on crude protein ranged from 15.85 to 18.27%, in-vitro protein digestibility (80.42-88.55%), calcium (48.53-56.25 mg/100g), zinc (2.42-3.56 mg/100g), iron (3.34-5.13 mg/100g), cooking time (8.50 - 19.50 min), water uptake ratio (1.15 - 1.90), lightness value (4.19 - 50.73) and colour change (4.47 - 51.13), respectively. The combined boiling and ultrasound treatment on Cirina butyrospermi powder and higher extrusion temperature gave rice pasta the highest protein, calcium, zinc, and iron content while lower extrusion temperature along with boiling treatment, increased in-vitro protein digestibility. Optimum conditions for desirable rice pasta were achieved at 80°C extrusion temperature with combined boiling and ultrasound treatment. Conclusively, exploring edible insects like Cirina butyrospermi under an accurate treatment method and extrusion condition could aid in the development of nutrient-rich rice pasta.

IntroductionAlthough reliable new evidence has identified several advantages of resistance training (ResEx) on cardiac performance, the role of this type of training in protecting the myocardium against ischemia-reperfusion (IR) injury is not clear. The aim of this study was to investigate the effect of resistance training on cardioprotection versus IR-induced injury.Material and methods60-day-old male Wistar rats (n = 24), weighing 220–240 g, were divided into four groups: Resistance Training (ResEx), Isoproterenol (ISO), Resistance Training + Isoproterenol (ResEx + ISO), and control groups (n = 6 for each). Trained rats performed exercise in a squat-training apparatus (8–12 repetitions/set, eight sets/day, and 5 days/week for 8 weeks). After the last training session, all the rats were sacrificed with ketamine xylazine injection. The heart of rats was removed from the body and washed quickly with cold PBS, immediately put in liquid nitrogen, and stored at –70°C. Superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT) activity was measured.ResultsInduction of ischemia decreased SOD and CAT activity but had no effect on the activity of GPX. Eight weeks of resistance training significantly increased activity of SOD and CAT compared to the ISO group.ConclusionsThe results of the present research demonstrated that ischemia induced by isoproterenol injection during 8 weeks of resistance training did not lead to a decrease in SOD activity and prevented the reduction of CAT activity.

Challenges Preventing Parents from Effectively Involving Themselves in the Implementation of CBC in Rwanda’s Lower Primary (Grades 1-3)
Authors: Bavugempore Jean de Dieu , Ngabonziza Jean de Dieu Amini 
Published: October 2024

The purpose of this study is to investigate the challenges that prevent parents from effective involvement in CBC implementation in lower primary grades. This study was founded on J. E. a. Epstein Theory of parental involvement which tackles parental involvement in six facets. This study adopted descriptive research design where qualitative and quantitative data were collected and analysed. We collected data from 3 schools of Karongi District where 45 parents having children in the three schools; 45 lower primary grade learners; 9 lower primary grade teachers; 3 head teachers and 1 district education official were selected as a sample. This sample was calculated from the total population of 1053 Parents, 1065 children, 31 teachers and 3 head teachers using the Systematic Random Sampling technique. To collect the Primary data, the questionnaires were administered to parents and learners while teachers, head teachers and a district education official were interviewed. The secondary data were collected from existing literature in relation to the current study. The collected data was analyzed qualitatively and quantitatively using descriptive statistics and thematic analysis. The results were organized in an Excel spreadsheet to be analyzed by SPSS package version 28.0. In this context, descriptive statistics have been applied where means, percentages, and frequencies were calculated. Findings revealed that the main factor that prevents parents from effective involvement in CBC implementation is a lack of knowledge of CBC and awareness about where and how to give their hands in supporting their children. This calls for the Ministry of Education not only to train teachers in CBC but also parents as they are key partners in implementing CBC.
