This study evaluates the logistics of sweet potato transportation in Offa and Oyun local government areas (LGAs) of Kwara State, Nigeria. to identify the types of sweet potatoes produced and the trans- port-logistics facilities available in the study area as well as to determine the factors affecting the choice of trans- portation used by sweet potato farmers/marketer in the study area. The study used descriptive statistics method and analysed the primary data gathered via a well-structured questionnaire. The study results show a significant relationship between efficient logistics and sweet potato transportation in the study area. Improving the trans- portation system can encourage farmers to work hard toward increasing sweet potato production. The research recommends that government should support sweet potato farming through the construction and maintenance of rural roads and make easy accessibility of loans from banks and cooperative societies to farmers and transport operators to acquire necessary/modern equipment and new vehicles needed as well as to reduce the price of petro- leum for effective and efficient production process. Description: Transportation helps in moving goods and people from one geographical location to an- other. Transportation, therefore, helps bring raw materials to the factory for processing, and finished products are delivered to the final consumers through various channels such as wholesalers and retailers (Ajiboye, 2011, Ade, 2004). Effective distribution of agro-com- modity and business activities occur with the aid of transportation system. The distribution of agricultural products between zones, regions, and nations is made easy and smooth because of the transportation system (Ajiboye & Afolayan, 2009). The transportation system therefore enables long distances to be reached quickly and encourages inter-regional and international trade. Kareem (2010) opined that logistics strategically manage the movement and storage of raw materials, parts, and finished goods throughout a production process from the suppliers to final delivery to customers. Logistics, therefore, plays an essential role in getting the right product to the right customer at the right time, in the suitable condition and place, in the cor- rect quantity, and at the right cost. 2023-01-01T00:00:00Z http://irepo.futminna.edu.ng:8080/jspui/handle/123456789/30745 Title: Socioeconomic Impact of Road Transportation to Rural Development in Oyun Local Government Area of Kwara State Authors: Ajiboye, A.O; Dere, G.I; Akorede, I.A; Anozie, R.N; Yisa, Mutiat Shittu; Adebayo, T.M Abstract: This study evaluates the socioeconomic impact of road transportation on the rural development of Oyun Local Government Area, Kwara State. The study employs the use of descriptive techniques and an observatory approach in data collection and analysis. The primary data was sourced by administering questionnaire to 200 people (community members and transporters) from the study area through random sampling. Descriptive statistics and multiple regression model were used to analyse the observation data. The findings revealed that the model summary in Table 10, using the R Square figure, show that the coefficient of the determinant value of 0.616, the independent variable account for 61% of the variability in the dependent variable. The impact of trip purpose, road condition, route type, accessibility, and means of transport on socioeconomic development of Oyun LGA is 61%, i.e. highly significant, as expressed by the coefficient of determinant variables. ANOVA table reveals the P-value of 0.000 (Significant value). Using the benchmark of <0.05, there is a 95% significant relationship between the socioeconomic development of Oyun LGA and trip purpose, road condition, route type, accessibility and means of transport. In contrast, 0.465 (46%) route type has no statistically significant relationship with the socioeconomic development of the rural areas. Furthermore, good and motorable roads, low cost of transportation, availability of vehicles, etc as recommended will enhance or boost the socioeconomic development of Oyun Local Government Area. The findings from this study reveals that construction of good roads, proper maintenance of roads, access to a good market and integrated development of rural areas will help boast the socioeconomic development of Oyun Local Government Area in Kwara State. Description: Rural development is a function of several factors in which transportation is of great significance. Non-clog rural transportation serves as one of the backbones for regaining and moving goods and services, people, information, and promoting the rural economy (Adedeji et al., 2014, Ajiboye andOlaogun, 2006). Transportation leads to economic development through the production area's linkage with the consumption area 2024-08-12T00:00:00Z http://irepo.futminna.edu.ng:8080/jspui/handle/123456789/30744 Title: Design and Implementation of 500W Remote Controlled Transformer-Less Solar System Authors: Yisa, Mutiat Shittu Abstract: Over 70% of the inverter systems are designed with transformers which are galvanic isolations. However, such inverters are big, heavy and expensive with low efficiency. In this work, a transformer-less PV system is introduced. It is smaller, lighter, and cheaper with higher efficiency as compared to the transformer of the same rating. The proposed inverter employs push pull circuit, an H bridge circuit, the oscillating circuit, an automatic changeover dual battery bank and an RF remote control circuit unit. The switching technique of the proposed inverter consists of a pulse width modulation system along with grid synchronization condition. As the suggested method is entirely transformer-less, there is a reduction in transformer loss which tremendously reduces the total harmonic distortion (THD) to even less than1% with an assumption of; inductor is ideal without any internal resistance, the switches and diodes are ideal with the dead line between the switches are neglected. A filtering capacitor provides a nearly constant output current which stabilizes the system rapidly and reduces harmonics generated by the switching circuit. Overall performance of the proposed inverter was simulated with PROTEUS and validated with MATLAB which produced a pure sinusoidal waveform as the output voltage. The proposed inverter minimizes size and increases the inverter efficiency to 90% which can be used in our homes, offices and schools for lightening and charging. Description: Power semi-conductor devices represent the heart of the modern power electronics and are being extensively used in power electronic converters in the form of ON or OFF switches, and helps to convert power from one form to another. There are four basic conversion functions that can be implemented such as:i. AC – AC converter (AC voltage controller) ii. AC – DC converter(controlled rectifier) iii. DC – DC converter (DC chopper) iv. DC – AC converter (inverters) Inverter is one of the converter families which are called DC to AC converter. It converts DC power to AC power to a symmetric AC output voltage at desired magnitude and frequency 2018-01-08T00:00:00Z http://irepo.futminna.edu.ng:8080/jspui/handle/123456789/30743 Title: Design and Implementation of 500W Remote Controlled Transformer-Less Solar System Authors: Yisa, M.
