objective(s):   the ongoing increasing antibiotic resistance is one of the biggest challenges faced by global public health. the perennial need for new antimicrobials against a background of increasing antibiotic resistance in pathogenic and opportunistic microorganisms obliges the scientific community to constantly develop new drugs and antimicrobial agents. lichens are known prolific sources ...

one of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. after choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. choosing a mining method depends on the geological and geometrical c...

Abstract Most studies about the automatic control of open canal irrigation systems only focus on distant downstream water level, which ignores fact that offtakes may be located anywhere along canal. Such a simplified strategy is likely to result in uncontrollable and inefficient delivery. Therefore, multi-point hydraulic method proposed, Saint-Venant model formulated describe states multiple co...

In scenes where there are lighting changes, localization may fail for visual SLAM due to feature point tracking failure. Thus, a method based on multi-condition constraints is proposed SLAM. The tracks the points of optical flow from aspects such as overall motion position points, descriptor grayscale information, and spatial geometric constraints. First, solve problem mismatch in complex envir...
