Bio-inspired propulsion of micro-swimmers within a passive cervix filled with couple stress mucus.

Background And Objective: The swimming mechanism of self-propelling organisms has been imitated by biomedical engineers to design the mechanical micro bots. The interaction of these swimmers with surrounding environment is another important aspect. The present swimming problem integrates Taylor sheet model with couple stress fluid model.

Investigation of sedimentation process of soluble spherical particles in a non-Newtonian medium.

In this work, transient movement of a vertically falling soluble spherical particle in a non-Newtonian medium is perused. It is supposed that the particle mass diminishes owing to its solubility in the fluid, and thus particle size will be diminished by a linear function. The governing nonlinear differential equation is solved analytically using Collocation Method (CM).

Metallo-β-lactamase-mediated resistance among clinical carbapenem-resistant isolates in northern Iran: A potential threat to clinical therapeutics.

Objective: Carbapenems are effective agents to treat multidrug-resistant (MDR) strains of bacteria, including . However, there is a potential threat of emergence of carbapenem-resistant (CRPA). The aim of this study was to determine antibiotic susceptibility patterns and metallo-beta-lactamase (MBL)-mediated resistance in clinical isolates.
