Abstract Soft actuators have attracted significant attention owing to their unique characteristics and potential for various applications.A dielectric elastomer actuator (DEA) is a type of soft actuator driven Rotary Cutters by electric voltage and has superior characteristics, such as a fast response, light weight, and simple structure.Several stu
The aim of this study was to characterize the prevalence of fecal carriage of extended-spectrum beta-lactamases and carbapenemase-producing Gram-negative bacteria among healthy humans in Tunisia.Fifty-one rectal swabs RNA of healthy volunteers were plated on MacConkey agar plates supplemented with cefotaxime or imipenem.The occurrences of resistanc
Calving of icebergs is a major negative component of polar ice-sheet mass balance.Here we present a new calving model relying on both continuum damage mechanics and linear elastic fracture mechanics.This combination accounts for both the slow sub-critical surface crevassing and the rapid propagation of crevasses when calving occurs.First, damage Po
In this paper, a method to improve the performance of PEMFCs using porous material as a flow channel baffle is proposed.The results show that PEMFCs with four porous Eye Makeup baffles flow channels have better performance at high current density compared with the traditional flow channel.The structural parameters of the flow channel explored in th
Human milk oligosaccharides (HMOs) exhibit various biological activities for infants, such as serving as prebiotics, blocking pathogens, and aiding in brain development.HMOs are a complex mixture of hetero-oligosaccharides that are generally highly branched, containing multiple structural isomers and no intrinsic chromophores, presenting a challeng
