Electrolysis process provides an effective route to reduce the energy consumption. In this paper, a three-dimensional electro-magneto-hydrodynamics coupling model of a 120 kA magnesium electrolysis cell using finite element method is presented. In this model, the electric field, magnetic field, and flow field are included. This paper concerns the effects of the Lorentz force on the motion of the electrolyte in the cell. The model predicts that the magnitude of Lorentz force is at its maximum near the region between the anode and cathode. The direction of the Lorentz force is beneficial to the motion of the electrolyte in the magnesium electrolysis cell. Index Terms – Electro-magneto-hydrodynamics, Lorentz force, magnesium electrolysis cell.

However, RZABs still face serious challenges (such as sluggish oxygen reactions, poor durability, inferior reversibility of the zinc anode, and low cell energy efficiency) that conspire against their widespread commercialization. The reactions that occur at the three key components of the RZAB (air cathode, zinc anode, and electrolyte) cooperatively conspire against its performance. Thus, this review focuses on the bifunctional electrocatalytic events at the cathode (i. e., oxygen reduction reaction (ORR) and oxygen evolution reaction (OER)). That is in addition to the recent developments aimed at mitigating the performance-limiting events at the anode and the electrolytes. This review directs the attention of researchers and users to the critical areas for the development of the next-generation RZABs.

Methodology: A total of 320 wound swab samples were collected from August 2016 to June 2017, and processed via microscopy, culture and further confirmed by biochemical tests. Kirby bauer disc diffusion test was used to determine the antimicrobial susceptibility pattern of Proteus spp isolated. Results: Twenty eight (28) samples yielded Proteus spp, giving a prevalence rate of 8.75%. Male patients were more affected (60.71%) compared to females (39.29%). Difference in sex in relation to rate of infection was statistically not significant (X2 =3.963, p<.01). Patients within the age group of 21-30 years (28.57%) recorded the highest bacterial yield while those of 61-70 years and >70 years (3.57% respectively) recorded the least. Patients suffering from Wound Sepsis and Burns recorded the most significant infection rate (28.57% respectively...
