- ItemDesign and Implementation of an Electrostatic Precipitator and Its Cleaning System for Small Scale Combustion(IIJSR, 2017-12) Adabara, Ibrahim; Hassan, Abdurrahman S; Hassan, Abdurrashid SA simple wire-plate electrostatic precipitator (ESP) was constructed in order to test the efficiency of collecting smoke particles from combustion of rubber-wood that is used as a source of biomass energy. The ESP contains collection cylinder electrode and 2 wire electrodes between cylinder. The maximum input voltage of the Wheatstone bridge circuit using a high-voltage neon transformer was 10.5 kV (DC). The gap between the cylinder and the distance between wires were adjustable. Results from the field test in a furnace indicate that the device could be used for a period of about one hour before cleaning the electrodes was required. The collection efficiency was decreased during the course of wood burning as the dust loading increased. Maximum efficiency was near 80% during the initial period. The distance between the collection plate electrodes had a greater influence on efficiency than the distance between the wire electrodes. The cleaning system used in this experiment was made from a row of PVC pipes to allow water to discharge radially to the cylinder electrodes on both sides. Efficiency was increased after 120. This ESP is suitable for small and medium-sized enterprises (SMEs) to alleviate the release of detrimental chemicals such as PAHs into the atmosphere.
- ItemMobile Applications and Agricultural Knowledge of Smallholder Famers in Kura Local Government, Kano State, Nigeria(International Journal of Scientific Engineering and Science, 2017) Adabara, IbrahimThis study was to investigate the relevance of mobile applications in enhancing the agricultural knowledge of smallholder farmers in Kura local government, Kano State - Nigeria. These are guided by assessing the relevance of mobile phones applications in agriculture to smallholder farmers. The study found that smallholder farmers use mobile phones mostly for making calls (85%), entertainment (50%), making transactions (45%), and social media (40%). Also, the study found that mobile phones seem to be relevant to smallholder farmers to research about market prices (65%), making calls to customers and other farmers (50%), and to get information about the market and availability of different commodities (50%). The study concluded that mobile phones could help smallholder farmers in Kura local government to improve their agricultural productivity by giving them access to basic financial services, new agricultural techniques, and new markets, in turn helping them to secure better prices for crops and better return on investments. As their income improves with each harvest, they can invest in better seeds, fertilizers, and chemicals.
