Various methods are now being applied to reduce the mobility and mortality that these diseases cause. Because of the implemented policies, there seem to have been several improvements. However, the constraints suggest inefficiency in eliminating the burden, necessitating a straightforward explanation. The systematic review and meta-analysis aimed are to investigate the reasons for the incomplete eradication of cholera disease in Sub-Saharan Africa. We were able to obtain pooled estimates using random effect models. Four experiments were excluded from the study because they were duplicated in the studies, 13 because of an outbreak did not occur, 13 publications did not include risk factors and odds ratios in their outcome analysis, and an outbreak occurred before 2013. The review points out that drinking contaminated water, consuming unwashed vegetables, and the use of poor publish toilet facilities enhance cholera in Africa. PubMed, Web of Science, EMBASE, and EBSCO were among the four meticulously and systematically searched databases using predetermined criteria or search strategies. Two independent reviewers recognized studies that met the selection criteria, and data was collected using validated methods.展开更多

The superhydrophobic coating, which has a robust and water-repellent capacity, can catch the air to form several “airbags” on the substrate’s surface, isolating the corrosion media. Various superhydrophobic coating preparation technologies have been suggested, but each has its own set of flaws. On the other hand, electrodeposition, as a relatively mature industrial processing application, offers distinct advantages. However, until now, there have been few reviews on the electrodeposition preparation of anticorrosive superhydrophobic coatings. Therefore, the author has described several fabrication techniques based on superhydrophobic coatings in this review, including the advantages and disadvantages. Superhydrophobic coatings conventional concepts and wettability, as well as the model wetting concepts, have been reviewed. The coating processing status and the corrosion-resistant potential through the electrodeposition of metal and comparable composite are detailly encapsulated. Furthermore, electrodeposition parameters, including current density, crystal modifiers, and a deposition time of the coating morphology, are reported, following the ultrasonic-assisted, jet, pulse, and magnetic field-induced electrodeposition, respectively, as the recently developed technologies for preparing a coating. Finally, technology limitation is shown as well as the obstacles and prospects, and the improvement of the superhydrophobic coating’s durability as a prospects research focus has been recommended.展开更多
