Antipsychotics have been a pillar in the treatment of schizophrenia since their introduction more than 60 years ago. Their variety in structures and receptor binding properties confers on them a complex clinical profile of effectiveness and risk of adverse side-effects. Although antipsychotics are best known for their therapeutic effects in schizophrenia, these are limited to the positive symptoms, with much less influence on negative symptoms or cognitive deficits. Moreover, although the newer (so-called second-ge [...]

Electrical submersible pumps (ESPs) are an efficient and reliable artificial lift method for lifting large volumes of fluids from wellbores at flexible rates. Despite their advantages, including high flow rates and real-time downhole telemetry, ESPs are prone to frequent and unforeseen failures under harsh reservoir conditions, resulting in costly production delays and interventions. This paper presents an integrated evaluation of ESP failure mechanisms based on an analysis of run and pull reports, dismantle inspec [...]

The work focused on modelling and optimisation of integrated renewable energy conversion technologies based on sunlight, wind, and biomass, with dual energy storage (battery and hydrogen), for Patani Island, Delta State, Nigeria. The study was aimed at satisfying the energy demand of the Patani Island community (5°13’43” N, 6°11’29” E). A mathematical model was developed to describe the integrated system, and a genetic algorithm was employed to optimize the allocation of energy demand, energy generation, and energy [...]

A thin film of PEO18Li(CF3SO2)2N(LiTFSI)-tetraethylene glycol dimethyl ether (G4)-Li1.4Al0.4Ge0.2Ti1.4(PO4)3-LiCl·H2O (LAGTP·LiCl) was prepared by addition of 1,2-dimethoxyethane (DME). The grain boundary resistance of PEO18LiTFSI-LAGTP·LiCl was considerably reduced by the addition of G4, and a large-sized thin film of the composite polymer electrolyte was prepared easily by the addition of 10 wt.% DME. The electrical conductivity of [(PEO18LiTFSI-2G4)-5 wt.% LAGTP·LiCl]-10 wt.% DME was 1.2 × 10-4 S cm-1 at 25°C, a [...]

As the demand for cleaner-greener energy surges owing to more nations adopting Net Zero Emission by 2050, wind turbine (WT) technology is increasingly poised as one of the technologies to match the demand. Capacity building in the development of cost-effective WT tower with improved reliability and safety has become critical to delivering Net Zero mandate. This research demonstrates implementation of Taguchi Design of Experiment (DoE) in conjunction with Signal-to-noise ratio (S/N) to optimise both structural desig [...]

Increasing local energy access in developing countries, particularly in off-grid regions where mini-grids are often overloaded, remains a critically underexplored area in energy transition. These regions often face significant technical and economic challenges, such as low generation capacity, high energy costs, limited energy access, and heavy reliance on diesel fuels. This study explores capacity expansion by integrating small-scale geothermal energy into such a mini-grid system to enhance the local energy supply [...]

The effective neutron multiplication factor (keff) of a fissile system is a function of space and time f(x, y, z, t), where (x, y, z) are the coordinates of the reference point in space, and t is time. The evidence of the time-dependence of the neutron multiplication factor of a fissile system was published in 2017. The spatial dependence is as important as the time dependence, as interacting arrays of fissile material during storage can lead to an increase in the system (keff). Therefore, evaluation of how the sto [...]

Taiwan relies heavily on imported fossil fuels, with over 98% of its energy demand supplied by foreign sources, posing significant challenges to national energy security. To explore alternatives, this study investigates the potential of marine renewable energy by developing a 20 kW floating hydrokinetic turbine prototype designed for deployment in the Kuroshio Current. The research encompasses system design, model validation, and both tank and at-sea testing to evaluate hydrodynamic performance and power generation [...]

This research introduces a blockchain framework to improve security and transparency for the use of renewable energy in power systems. The framework utilizes a permissioned blockchain architecture and IoT-based real-time monitoring to ensure data integrity and confidentiality and support efficient peer-to-peer (P2P) energy trading. Compared with traditional centralized energy management systems, the proposed design increases transaction security by 35%, decreases verification wait times by 28%, and decreases the ri [...]
