“…Renewable energy solutions offer a means of providing stable energy to many of these areas (Benjamin and Dickson, 2017) (Shrestha et al, 2019). Sustainability is also an issue as their main sources are non-renewable and are fast depleting in availability due to the high magnitude of usage over the years (Babalola et al, 2022) (Emetere et al, 2020) Sources like fossil fuels and nuclear elements have been in use for energy generation for a long time, and these sources have served large populations of high-load demands for years with high efficiency (Faizan (Orovwode et al, 2018). However, these conventional sources have had adverse effects on the environment like air pollution and global warming due to the effluents being generated and released during their operations (Shafiullah et al, 2020) (Mandal et al, 2018).…”

Electricity is vital to the economic growth any nation, as access to it, is key in achieving economic development. However, a stable electricity supply is lacking in the country, and with the increasing demand, it will be impossible to attain with the current infrastructure. This paper aims to carry out feasibility study of a hybrid energy system (HES) for sustainable power supply in Bakori Local Government Area, Katsina, Nigeria. The simulation results were generated using HOMER (Hybrid Optimization of Multiple Electric Renewables) software utilizing the solar system, and wind generator resources to satisfy the residential energy requirement for the case study. The proposed HES was compared with other configurations in terms of cost and energy production. The simulation results depict that the PV/Wind/Battery system is a viable hybrid energy system with a Net Present Cost of ₦3.62M and an electricity generation of 1,423,132 kWh/yr compared to the other configurations which produce less energy at a higher Net Present Cost.

Background: Emvolio is a non-medical device, indigenously developed portable refrigeration for maintaining the internal temperature 2–8˚C. The Indian Patent Office has granted patent for applications such as preservation and transport of medicines, vaccines, food, beverages, dairy etc. Further, use of Emvolio can be utilized in transport and store biologicals to preserve their biochemical and cellular integrity. The objective of this study was to evaluate the biochemical and haematological integrity of biological samples such as rat blood, serum and liver. Methods: The steady temperature was maintained inside the Emvolio, and it was compared to that of thermocol and polypropylene boxes aided with frozen gel packs. The blood and liver samples were isolated from Wistar rats and kept in Emvolio, thermocol and polypropylene boxes for 10 hrs, and the temperature was monitored. The blood parameters, namely red blood cells (RBC), white blood cells (WBC), platelets, haematocrit, haemoglobin, mean corpuscular volume (MCV), mean corpuscular haemoglobin concentration (MCHC) and red cell distribution width (RDW), serum parameters like alanine transaminase, alkaline phosphatase, total protein, albumin, creatine kinase, blood urea nitrogen and liver parameters like superoxide dismutase (SOD), glutathione (GSH), catalase were estimated and compared. Results: Emvolio maintained a constant inner temperature range of 2–8˚C, whereas a significant temperature variation was seen in thermocol and polypropylene boxes. There was no significant deviation in the parameters tested when samples were kept in Emvolio for six hours compared to the zero hour readings. In contrast, there was a significant deviation among the parameters for the samples kept in thermocol and polypropylene boxes for six hours compared to zero hour parameters. Conclusions: Emvolio maintained constant temperature and preserved the biological integrity of rat blood, serum and liver. Thus, Emvolio can be efficiently used as a biological sample carrier, especially in preclinical studies.
