ABSTRACT

The physico-chemical and microbiological quality of honey samples obtained from the Niger Delta region of Nigeria were investigated. There is paucity of information on the physico-chemical characteristics of honey produced from the Niger Delta region of Nigeria; hence, the need to provide a database on the characterization of honey produced in this zone. A total of eighteen honey samples collected from this zone were analyzed for their chemical properties including moisture, ash, pH, glucose and fructose content, while the microbial population including total plate count (TPC), total coliform and the levels of spore-forming bacteria and fungi were determined. Data obtained were analyzed statistically by Analysis of Variance (ANOVA), while sample means were separated with the aid of Least Significant Difference (LSD) at P ≤ 0.05 using Statistical Analysis System (SAS) package. The mean moisture content values ranged from 12.32 – 34.02 %, while the mean ash content ranged from 0.74 – 1.22 g 100 g-1. The mean pH value of 2.6 obtained from honey samples collected in Akwa Ibom was significantly very low when compared with that of 4.3 and 3.2 obtained from Edo and Bayelsa States honey samples respectively. Glucose and fructose mean values detected in honey samples also showed significant values. Four mineral elements: Potassium (K), Magnesium (Mg), Calcium (Ca) and Iron (Fe) were detected, but with levels varying from one place to another. Potassium (K) was the most abundant element with a mean value of 8.06 ppm obtained from Akwa Ibom honey samples. Results of microbiological characteristics showed that microbial profile were low for all microorganisms detected in honey samples produced from the tropical Niger Delta region of Nigeria.

ABSTRACT

Weed infestation is one of the major constraints in rice production, hence the need to evaluate integrated weed control in its production. Field experiments were carried out at Teaching and Research Farm of Taraba state college of Agriculture Jalingo (80 54’ N 11o 22’ E) to evaluate the effect of mulching and inter-row spacing on weed control and yield of upland rice during 2018 and 2019 farming seasons. Two sets of factors were considered in the experiments, first factor consisted of three mulching treatments (no mulch, maize straw mulch and rice straw mulch) while the second factor were three inter-row spacing (25 cm, 30 cm and 35 cm) were laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were collected on weed density, weed biomass, grain yield and yield components of rice. On the average, rice straw mulch reduced significantly weed density (42.18 no/m2 and 25.34 no/m2) and weed biomass (25.42 g/m2 and 13.21 g/m2) than weed density (289.88 no/m2 and 94.74 no/m2) and weed biomass (88.55 g/m2 and 49.84 g/m2) at 3 and 7 WAP, besides, rice straw mulch also recorded significantly higher average grain yield (4.19 t/ha) than no-mulch treated plots (1.587 t/ha). Although 25 cm inter-row spacing recorded significantly lower average weed density (62.86 no/m2 and 40.14 no/m2) and weed biomass (23.32 g/m2 and 16.08 g/m2) than average weed density (90.22 no/m2 and 69.06 no/m2) and weed biomass (45.40 g/m2 and 33.67 g/m2) in 30 cm inter-row spacing, the average grain yield was significantly higher (5.099 t/ha) in 30 cm inter-row spacing.Key words: weed control, rice straw, maize straw, inter-row spacing, mulching

ABSTRACT

Nigeria as a nation has suffered a lot when it comes to the availability of electricity. A clear comparison between this nation’s electric power supply and other countries revealed the present incessant electric power supply in the country. The average power per capital (watts per person) in the United States is 1,377 Watts. In Canada, it is as high as 1,704 Watts per person and in South Africa; it is 445 Watts per person. The average power per capital in Australia is 1,112 Watts and in New Zealand it is 1,020 W per person. Whereas, the average power per capital (watts per person) in Nigeria is 14 W person. The power system structure is characterized with a lot of faults and outages. These electric power problem has destroyed the industrial processes in the country. As a result, unemployment has increased in the country. As at February, 2020, according to the Federal Government of Nigeria, the number of unemployed youths in the country is 23 million. Data from the International Transparency in the United State stated that there are 40 million unemployed youths in the country. This has increased crime rates among the youths. The country experience a high level of hardship, insecurity and socio-economic disorder as results. Therefore, there is an urgent need to solve this incessant supply of electric power in the country. Hence, a detail study of Akure132/33kV substation Network of the Benin Electricity Distribution Company under which there are 84,264 customers was carried out.  Reliability index of the distribution system were estimated. A model for establishing a hydro Electric Power Generating Plant was developed. Power Generation and Improvement techniques for the generation, transmission and distribution of electricity were achieved. The research work developed a model for establishing a hydro Electric Power Generating Plant and establish a monogram for increasing the value of power generation in a hydro generating station.

ABSTRACT

Mobile phone (also known as Global System for Mobile Communications (GSM), cellular phone, cell phone and hand set) is a device that can make and receive telephone calls over a radio link. Telecommunication industry is experiencing a robust growth on a global scale and cell phones are becoming essential tools in the global modern society. This paper discusses the health implications of mobile phones such as thermal and non-thermal radiation effects. It also highlights the methods of evaluating average exposure using statistical tools, and using digital signal processing techniques called Fast Fourier Transform in examining the effect of electromagnetic radiations on human brain. With respect to radiation from cell phone, it is found from literature that the rate at which energy is absorbed by the human body is measured by the specific Absorption rate (SAR) so as to avoid various health problems such as deafness, migraines, high blood pressure, brain cancer, etc.
