Authors: Njoku T.C. 
Published: March 2023

A-three-year trial of flowering phenological characteristics of 150 African pear tree were studied in South-South and South-East Nigeria to study the flowering phenology of African pear (Dacryodes edulis) under Nigerian Ecological conditions. Five States were selected, three locations in each State, ten mature African pear trees were selected and tagged for data collection. Also, meteorological data were collected for three years. The surveyed trees were monitored till flowering time. Data were collected on start of flower formation, peak of flowering, days to anthesis, average temperature and rainfall during the months of flowering. Data collected were analysed using analysis of variance and percentages were calculated where appropriate. Result obtained indicated that there were variations in the time of flowering. African pear had peak flowering in January in Imo, Rivers and Delta States for 2013-2015, while Abia and Enugu had their peak flowering for the same period in February and March, respectively. African pear flowered between the temperatures of 27.0oC to 29.5oC. Rainfall ranged from 0.00mm to 137.50mm. The flowering season was affected mainly by temperature. Time of inflorescence flower bud formation to anthesis lasted for 2-5 days, but majority took 3-4 days to reach anthesis. In the study, under Nigerian ecological condition, African pear flowered when the temperature was high and when humidity was low. The planting of African pear that flowers around January and February should be encouraged because they had the highest yield and potential to ripe during hunger period.

The mutagenic effect of Colchicine on the morphology and yield of tomato was investigated. Seeds of three tomato accessions (NG/MR/May/09/005- SouthWest, NG/SA/07/10/002- NorthEast and NG/CHU/Jun/0201-SouthEast) were presoaked in four different concentrations of Colchicine (0.1mM, 0.3mM, 0.5mM, 1.0mM) and 0.0mM as control. The domestic demand for tomato extremely exceeds the supply with over 2-3 million metric tons annually thereby involving Nigeria into importing about 300,000 metric tonnes worth over $360 million dollar yearly. The experiment was laid in Randomized Complete Block Design in five replications. The morphological parameters used to characterize the mutants were plant height, number of leaves/plant, leaf length, number of branches, number of days to first flowering, fruit weight, germination percentage and number of fruit/plant. The results revealed significant difference (p<0.05) in some of the morphological traits assessed when compared with the controls, except in the number of branches and plant height, where the effect of the mutagen was not important (p>0.05). The morphological and yield parameters of the southwest and northeast accessions of tomato as observed in this study, improved with decreasing concentration of Colchicine, while the southeast improved with increase in the concentration of Colchicine. It is thus recommended that, to improve growth and yield parameters in tomatoes, 0.1mM concentration should be employed to improve Southwest and Northeast tomato accessions, while 0.5mM or 1.0mM concentrations should be used in the Southeast tomato accessions.

This study investigate the effect of converting Bacopa floribunda BF leaves into Bacopa florbunda black herbal tea BFHT on the mineral profile, antinutrients, antioxidants, Anticholinesterase and lipid peroxidation inhibitory properties of Bacopa floribunda leaves. Bacopa floribunda leaves were plucked, destalked, withered, rolled, fermented/oxidized, milled, dried, cooled and packaged. The antinutrients phytate, saponin and tannin content of B. floribunda leaves reduced significantly (P ˂ 0.05) after processing into BFHT. The mineral ratios and molar ratios of minerals BFHT were within the critical values making them available for absorption. BFHT exhibited a very high and significant (P ˂ 0.05) total phenolics (60.08 mg GAE/g), total flavonoids (12.96 mg QE/g) and reducing power (50.38mg AAE/g). The scavenging activities of BFHT extract against DPPH and Nitric oxide (NO) was significantly (P ˂ 0.05) higher than freshly harvested B. floribunda leaves. BFHT (IC50 = 74.26 μg/ml) demonstrated a high significant (P ˂ 0.05) inhibitory capacity against Acetyl cholinesterase enzymes. The inhibition capacity of BFHT (IC50 = 0.65 μg/ml) against Fe2+ induced lipid peroxidation was significantly (P ˂ 0.05) higher than freshly harvested B. floribunda leaves (IC50 = 0.78 μg/ml). The study has demonstrated that high quality herbal tea BFHT could be produced from B. floribunda leaves and also serves as another method of food preservation.

Published: March 2023

Elderly are one of the fastest-growing population globally and require significant healthcare services due to age-related deterioration in physiological systems. Poor postural control due to aging results in impaired balance leading to increase in frequency of falls, poor quality of life, and rise in disability and mortality rates. In Pakistan, due to lack of awareness, and resources, fall prevention and screening programmes for the elderly are lacking. Regular fall risk screening utilizing balance assessment tools, integration of fall prevention programmes and balance rehabilitation approach as part of elderly healthcare services can serve as tools to lower the incidence of falls in the elderly population of Pakistan. Moreover, integration of latest technology as part of balance rehabilitation can also be considered. The review aims to highlight appropriate strategies for fall risk screening and balance rehabilitation in an effort to promote an important healthcare intervention for elderly in Pakistan.

Authors: Ikotun Olumoroti , Shehu Suleiman 
Published: March 2023

Purpose: Some previous researchers work on the HVDC Monopolar systems using Matlab/Simulink environment to carry out their analyses. We continue this discussion of Monopolar HVDC systems.
Methodology: The analyses that are carried out include double phase-to-ground fault, single phase-to-ground fault and three phase-to-ground fault at the AC side of the rectifier and the DC line to ground fault.
Findings: It is discovered, among others, that for three phase-to-ground fault, the voltages at the AC side of the rectifier, the DC line voltage and the voltage at the inverter side of the load are completely zero but that the current in the rectifier will increase from its standard value though will be less harmful and the current of the inverter side will decrease from its original value. It is further discovered that the fastest transient will be the case when fault is applied to the DC transmission system and that transmission network is of critical importance in high voltage transmission lines and engineers can also use this result to identify different faults in the transmission lines and the care of power quality is highly important because of electrical energy demand.
Unique Contribution to Theory, Practice and Policy: The current in the rectifier decreases from its standard value but will be less harmful. The causes of decrease in DC transmission line depend on severity of the fault such as single phase to ground, double line to ground and three phase-to ground at the rectifier side.
