Electricity is essential for economic growth, natural development and improved standard of living. Most of the existing water supply dams available in the rural areas can be used for power generation without affecting its primary functions. This will lead to a high saving in cost since there is no need for construction of new dams. However, integrating a convectional hydro turbine into an existing dam that is not originally designed for power generation may bring up some major technical issues. Moreover, the seasonal variation of water especially during dry season poses a great challenge in meeting the electricity demand at all times. This study explored technical analysis for Small hydropower (SHP)’s installations in an existing water infrastructure and formation of dam based-small hydro Hybrid Power System (HPS) in which solar Photovoltaic (PV) system and Diesel Generator (DG) are integrated. Ele water supply dam located in a typical rural village, Itapaji-Ekiti, Nigeria and currently being used to supply portable water to thirteen villages in the area, was used as a case study. Local weather data (such as stream flow and solar radiations) were obtained and analyzed using Hybrid Optimization Model for Electric Renewable (HOMER) software. The results obtained showed that the Cost of Energy, (COE) of SHP-PV-Battery-DG hybrid system is $0.166/kWhr while the COE of the PV-Battery-DG hybrid system combination is $0.290/kWhr. The outputs of the simulations also showed an acceptable power quality for the hybrid power system. The study is expected to be a cost-effective electrification solution to the rural dwellers.

An original method for producing low electron temperature and high electron density plasma was studied experimentally by using a rectangular grid-cage as a capacitively-coupled powered electrode in a radio frequency (RF) discharge.

A rectangular grid-cage electrode was placed on a side wall of a grounded cubic-box chamber of 15x15x15 cmin volume. The cubic chamber was situated in a stainless steel vacuum chamber 60 cm in diameter and 100 cm long. An argon plasma was generated by a 40 MHz power source in a pressure range of 2.0 ~ 6.7 Pa. RF power PRF of 5 ~ 60 W was supplied to the grid-cage electrode directly through an impedance matching circuits with a dc blocking capacitor for efficient plasma production.

The electron temperature Te and electron density nwere found to be strongly dependent on a mesh size of grid-cage electrodes. If the mesh of the grid-cage was fine, T decreased, while ne  increased, compared with those in the case of a coarse grid-cage electrode. By using a fine grid-electrode, Te dropped down to 0.5 eV, while ne reached up to 1.62x1011 cm-3  at the center of the cubic discharge chamber of 15x15x15 cm3under argon pressure of 2.0 Pa and RF power of 60 W.

This discharge method easily provides low electron temperature and high density plasmas under the continuous RF discharge.

The cost of acquiring real time, high resolution spatial datasets required for effective management of plantation has been a major challenge to farm management in developing country like Nigeria. But recent commercialization of Unmanned Aerial Vehicles (UAVs) has gradually made an affordable means of acquiring these spatial datasets available to individuals and small organizations.

This study counts the palm trees in a palm plantation by template matching of digital orthophoto produced by a low cost Unmanned Aerial Vehicle. An aerial survey was carried out at Obafemi Awolowo Teaching and Research Farm using Phantom II Vision quadcopter. Using a flying altitude of 100 m, the plantation, which covers a land area of about 56,0002 m and containing 663 mature palm trees, was surveyed using the UAV. An 11 cm Orthophoto and Digital Surface Model (DSM) were produced. Template Matching algorithm was used to extract individual palm tree stand unto a thematic vector layer. The palm tree distribution map was produced after errors have been corrected using the DSM.

The procedure shows that there are 572 palms present in the plantation with 86.27% accuracy in comparison with manual counting. The distribution of the palms in the plantation indicates underutilization of the plantation due to presence of empty and uncultivated area in the plantation. Also, there are presence of foreign trees in the plantation which might be competing with the palm trees for nutrients and thereby reducing the total yield of the plantation.

The dry-frying process is the most critical operation in the processing of cassava (Manihot species) into ‘gari”. The local technique of ‘Garification’ in batch operations was found to be most dependent on prevailing processing temperature with regular agitation. The temperatures of customised fryer was recorded every 3 min of the ‘garification’ process until the process is completed. The moisture content of dewatered 5 kg mash at 40-50%, was reduced to an acceptable moisture content of 12.5% at temperatures in the range of 27–165°C. The energy profile was found to follow a particular profile of dehumidification for the first 7 min, evaporation cooking between 8 to 12 min, drying at about 15 to 22 min and frying for about 5 min before cooling in a 30-35 min batch cycle. A swelling index of 3.4 as a mark of good product was achieved. The moisture content and the temperature were also influenced by the particle size of the mash and the cake density. These series of operation occurred consecutively and are all dependent on the prevailing temperature and duration of treatment. The Energy profile can be used for small and medium scale design, fabrication and processing of cassava to obtain suitable product. It can also form a precept to automation or as a complementary processing technique in an emerging mechanized gari fryer.

Aims: The aim of the study was to determine the demand for waste collection services, awareness on solid waste management and constraints to proper waste management for the community within and around Egerton University, Njoro Campus.

Study Design: The research design was a cross-sectional survey whereby data was only collected once from the respondents.

Place and Duration of Study: The study was carried out in Njoro and Mukungugu sublocation within Njoro location, Njoro division in Nakuru County, Kenya in the period January to December 2009.

Methodology: A sample of 220 was drawn from students, tenants, farmers and the business people from within Egerton University and the community around it. A proportionate stratified and systematic sampling design was used. Structured questionnaires were used in data collection whereas analysis was by descriptive and test statistics by use of the statistical Package for Social Sciences.

Results: Only 3.7% of the respondents reported paying to have their waste collected and disposed while about 40% of those not currently paying were willing to start paying. Only age had a significant influence on amount of money respondents were willing to pay for waste collection while income, education level and awareness did not. The study established that awareness was generally low although it was significantly higher for the population within the University (t=3.594, d.f.=218, p<0.001). The main constraints identified were inadequate knowledge/awareness on proper waste management, irresponsibility and lack of disposal sites.

Conclusion: It was concluded that there is need for improved waste management in the area which can be done by developing a waste management strategy for the area, more engagement of the informal sector in waste management and sensitisation of the community on sustainable waste management.

DOI: 10.9734/JSRR/2016/19538

Aims: To identify the factors that drive graduate students to adopt technology applications in their learning process and thereby we offer insights into the design and implementation of new learning methodologies and resources.

Study Design: Utilization of audio-visual cases in an e-learning environment.

Place and Duration of Study: Open University of Catalonia (Spain), May 2012.

Methodology: This study has involved a sample of 32 business students and has an exploratory nature. Due to the small sample size we used non-parametric statistical techniques and the Mann-Whitney U test to determine if students’ perceptions reflected their assessments on material design and its effects on the development of their academics activities. Among non-parametric statistical techniques, the Mann-Whitney U statistic is comparable to an analysis of variance in samples that are less than 30.

Results: Among this sample, 56.5% are women. With regard to age, more than 60% fall in the range of between 25 and 45 years of age, and of these, 53% are older than 35 years. In relation to experience, 52.2% indicate they have more than 15 years’ work experience. Yet we found no significant differences across these categorizations in terms of students’ perceptions of the audio-visual material. So, students between 25 and 35 years of age consistently present very positive perceptions of the use of these materials, and for the more specific category of 35–45 years, the percentage increases to 76.5%. When students have significant work experience, 58.5% of them express positive perceptions of the use of audio-visual materials.

Conclusion: Students express positive attitudes toward a new technological resource “audio-visual cases”, noting that this tool improved their comprehension of the problem and its origin. In addition to revealing which elements influence in students’ adoption of new methodologies and resources that rely on intensive technology use.
