The impact of zinc pre-exposure on ciprofloxacin resistance development in E. coli

open access: yesFrontiers in Microbiology
IntroductionAntimicrobial resistance (AMR) is a global health crisis that is predicted to worsen in the coming years. While improper antibiotic usage is an established driver, less is known about the impact of other endogenous and exogeneous ...

Trapping and Mobilization of Residual Fluid During Capillary Desaturation in Porous Media [PDF]

open access: yesarXiv, 1999
We discuss the problem of trapping and mobilization of nonwetting fluids during immiscible two phase displacement processes in porous media. Capillary desaturation curves give residual saturations as a function of capillary number. Interpreting capillary numbers as the ratio of viscous to capillary forces the breakpoint in experimental curves ...

Refugees and the Ethics of Forced Displacement [PDF]

open access: yes, 2016
This book is a philosophical analysis of the ethical treatment of refugees and stateless people, a group of people who, though extremely important politically, have been greatly under theorized philosophically. The limited philosophical discussion of refugees by philosophers focuses narrowly on the question of whether or not we, as members of Western ...

Development of Ternary Magnesium Alloys for Laser Powder Bed Fusion: Optimizing Oxide Layer Thickness

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

Dislocations in the Field Theory of Elastoplasticity [PDF]

open access: yesComputational Materials Science 28 (2003) 419-428, 2003
By means of linear theory of elastoplasticity, solutions are given for screw and edge dislocations situated in an isotropic solid. The force stresses, strain fields, displacements, distortions, dislocation densities and moment stresses are calculated. The force stresses, strain fields, displacements and distortions are devoid of singularities predicted

Anomaly Detection Method for Hybrid Workpieces Using Dynamic Time Warping

open access: yesAdvanced Engineering Materials, EarlyView.
Monitoring of hybrid workpieces: when machining hybrid workpieces, unavoidable axial deviations of the material transition zone cause temporal shifts in the process force signals. A new anomaly detection method based on dynamic time warping is proposed to detect material defects.

Forced displacement [PDF]

open access: yes
El desplazamiento forzado en Colombia se convertido en uno de los flagelos más grandes que el país ha vivido durante sus últimos 70 años por esto es importante identificar cuál es su origen y como este fenómeno social ha llevado a personas a convertirse ...

Resonant forcing of nonlinear systems of differential equations

open access: yes, 2008
We study resonances of nonlinear systems of differential equations, including but not limited to the equations of motion of a particle moving in a potential.
