Displaced farmers perception of resource- use conflicts as an obstacle to household food security and food safety in Abia State, Nigeria
Get PDFA journal article on resource- use conflicts as an obstacle to household food security and food safety. The article has tables and Impact Factor: RJIF 5.16 . This article was co-authored with staff of FUTOConflicts occasioned by different land users have become common place now. When farmers are displaced from their ancestral home due to conflicts involving pastoralists, life becomes difficult and unbearable. This paper investigates displaced farmers perception of resource use conflicts as an obstacle to household food security and food safety. A total of 300 displaced farmers were selected for interview and data obtained were analyzed using mean and standard deviation. Result showed that conflicts create food shortage (M=3.43), destroys food stocks (M=3.57), disrupts production processes (M=3.28), reduced farm investment (M=3.19), among others. Again, during conflict situation, food items are easily contaminated with mean score of 3.27, foods are handled with dirty hands (M=2.58), unsafe water could be used to prepare food (M=3.31), outbreak of food borne illness (M=2.92), poor quality of food eaten (M=3.31), among other reasons. It is recommended that adequate food be supplied to the displaced farmers in the form of aid, water supply be provided to displaced farmers and health facilities put in place to handle case of illness and to avoid spread of illnesses
Assessment of surface water quality of Onuiyieke River in Imo State , Nigeria
Get PDFA Master's thesis on surface water quality of Onuiyieke RiverThe surface water quality of Onuiyieke River was assessed for a period of six months (September, 2017 - February, 2018) at seven sampling locations (SLs) to ascertain its quality status. Measurements were made on samples collected with 500ml sample bottles according to standard methods. Samples for heavy metals were collected in 250ml bottle and fixed with concentrated HN03. Descriptive analysis, variation plots, ANOVA, Duncan Multiple Range tests, Principal Components Analysis (PCA), Pearson Correlation (r) and Water Quality Index (WQI) were used to analyze data. Mean values of the parameters obtained were: Total Suspended Solids (TSS) 198.19 ±80.93mg/L; Electrical Conductivity (EC) 331.81 ±59.78µ; Turbidity 18.84 ± 2.22 NTU; Nitrate ions 14.77 ±0.92mg/L; Dissolved Oxygen (DO) 6.58 ±O.22mg/L and Biological Oxygen Demand (BOD) 1.77±0.10mg/L. Mean values of the Trace Metals obtained were: Iron (Fe) 1.93 ±0.23mg/L; Magnesium (Mg) 0.22±0.02mg/L and Calcium (Ca) 15.15±1.87mg/L while the mean value of Faecal Coliform was 1.91±O.10MPN/100. pH, EC, TSS, BOD5, turbidity, N03-, Ammonia, Fe and faecal coliforms exceeded the NESREA and WHO maximum permissible limits. There were significant spatial differences in levels of TDS, EC, NO3, NH3, DO and Faecal coliforms (Sig F=0.000 to 0.039) and significant temporal differences in levels of PO43- (Sig F= 0.078 to 1000) between the control and other locations.at p<0.05. Four Principal Components (PCs) formed the extraction solution with a cumulative percentage variability of about 77.67 %. PCs 1, 2, 3, and 4 were most highly correlated with Mg2+ (0.925), NH4 (0.903), TSS (0.930) and temperature (0.840) respectively. The Water Quality Index revealed that the rating for the water quality across the sampling locations was between excellent and unsuitable with SL 3 having the least water quality. Appropriate monitoring procedures for the sustainable development of the river should also be put in place
Biochemical effects of Piper Guineense (African Black Pepper) in female diabetics: Opportunities for diabetes treatment
No full textThe article contains tablesObjectives: To investigate the biochemical effects of oral doses of Piper guineense (P. guineense) leaf extract on female diabetics using experimental animals. Methods: The animals, albino wistar rats, were divided into six groups (n=7). Animals in group 1 received water and feed only. Animals in groups 2 to 6 were induced with diabetes using alloxan. Methanolic leave extracts of P. Guineense were administered to groups 2 to 4 in 40 mg/kg, 80 mg/kg and 100 mg/kg body weights representing low, medium and high doses respectively. Group 5 animals were treated with 10 mg/kg body weight of Glibenclamide (Antidiabetic drug) and group 6 animals were left untreated. All treatments were carried out orally and lasted for a period of 14 days. At the end of the 14 days, the animals were humanely sacrificed through cardiac puncture and the blood samples collected for the analyses of some liver and kidney function parameters using assay kits. Results: The results showed that the oral doses of methanolic leave extract of P. guineense had no negative alterations on the biochemical parameters analyzed namely, 1) Lipid profile (Triglyceride, Low Density Lipoprotein, Total Cholesterol and High-Density Lipoprotein levels), 2) electrolytes profile (Sodium, Potassium, Chloride, Bicarbonate, 3) Urea) and 4) Creatinine levels. Furthermore, there was a significant reduction in the urea levels of treated animals and marked but insignificant reduction in the total cholesterol level and increase in High Density Lipoprotein at P<0.05. Conclusion and Implication for Translation: The reported antidiabetic P. guineense leaf extract caused no adverse biochemical changes in female diabetic rats. This implied that the extract may not distort the lipid and electrolyte profiles of female diabetics and could be pharmacologically safe in the management of female diabetics. It further implied that the Piper, Uziza, commonly taken after childbirth by nursing mothers in some tropical countries may maintain the lipid and electrolyte balance and consequently, prevent hypercholesterolemia and hypertensio
The impact of mentoring programs for sustainable career development and work/life balance in Biomedical Engineering profession - Short communication
No full textThe article has tables and figuresThe socio-economic, technological and emotional imbalance remains an issue of individual growth in career development and work-life balance. The impact of mentoring programs for sustainable career development and work and lifestyle balance in biomedical professions was examined. Career development was studied using self-assessment, career awareness, performance, skill acquisition, goal setting and work-life style balance. Career development can be achieved with pleasure if the essential routes were addressed by the parties
involved in mentoring programs. Proffered solution of organizational support, social support, use of modern facilities and self-assessment were recommended as tools for mentoring programs that reduced pain, depression, friction and wear, and emotional stress of mentors and mentees. Thus, provide an outstanding strength of social, economic, technological and emotional output as well as good healthy conditions for career development and stable work-lifestyle to achieve a set goal and target in biomedical engineering profession

A comprehensive review on the feasibility and challenges of millimeter wave in emerging 5G mobile communication
No full textThis research article contains graph and tablesThis article presents a comprehensive review on the feasibility and challenges of millimeter wave in emerging fifth generation (5G) mobile communication. 5G, a multigigabit wireless network is the next generation wireless communication network. The mmWave cellular system which operates in the 30-300 GHz band has been proposed for use as the propagation channel. Its large bandwidth potential makes it a candidate for the next-generation wireless communication system which is believed to support data rates of multiple Gb/s. High frequency bands such as mmWave have channel impairments. These impairments are challenges that are necessary to be properly understood. Employing mmWave as a propagation channel requires dealing with these challenges which this paper is aimed at reviewing. One aim of the work is to discuss these challenges in a more elaborate manner using simple mathematical equations and graphics to ensure clarity. To achieve this, current related works were studied. Challenges and solutions are identified and discussed. Suggested research directions for future work are also presented. One is developing suitable electronic such as fast analog-to-digital (ADC) and digital-to-analog (DAC) systems necessary for the transmitter/receiver (TX/RX) system
