Antibiotic-induced lateral transfer of antibiotic resistance

Trends in Microbiology, 2004
As do many temperate bacteriophages, integrating conjugative elements (ICEs) recruit the SOS DNA damage response to mobilize themselves from the bacterial chromosome and infect other cells. This transfers resistance to multiple antibiotics. Several commonly used antibiotics induce the SOS response, potentially hastening genetic change and the evolution

Retinal resistance barriers and electrical lateral inhibition

Nature, 1975
EXTRACELLULAR fields around active neural tissues are usually only a small fraction of the transmembrane voltages generating them, but this is not so in the arthropod compound eye. Light-evoked fields (the electroretinogram, ERG) can range over 10 mV amplitude1 and grow even larger near the receptor endings at the first synapse, the lamina (Fig.

Low resistance laser formed lateral links

IEEE Electron Device Letters, 1982
A new technique is described for reliably forming low resistance links by using a laser to bridge a lateral gap between two Al conductors deposited on insulating polysilicon. Resistances in the range of 1-10 ohms were achieved for gap widths of approximately 2-3 microns using 1 msec pulses from an argon laser. This technique should be ideally suited to

Piecewise 1D laterally constrained inversion of resistivity data

Geophysical Prospecting, 2005
ABSTRACTIn a sedimentary environment, layered models are often capable of representing the actual geology more accurately than smooth minimum structure models. Furthermore, interval thicknesses and resistivities are often the parameters to which non‐geophysicist experts can relate and base decisions on when using them in waste site remediation ...

Computer interpretation of lateral resistivity logs

5th EEGS-ES Meeting, 1999
Reservoir rocks parameters evaluating in particular determination of effective porosity and water, oil or gas saturation is based on resistivity logs measured in boreholes. It is realised in stationary variants (classical resistivity logs and laterologs different types) and in variants using electromagnetic fields (induction and EPT).

Modelling azimuthal resistivity sounding over a laterally changing resistivity subsurface

Near Surface Geophysics, 2004
ABSTRACTRotational or azimuthal resistivity sounding is frequently employed for determining the electrical anisotropy of the subsurface. From this, the orientation of fracturing which might give rise to the anisotropy is interpreted. However, 4‐electrode arrays, such as the Wenner or Schlumberger, are strongly ambiguous and will produce an anisotropy ...

Theoretical Lateral Resistance of Nailed Joints

Journal of the Structural Division, 1971
This paper presents results of a theoretical analysis based on behavior of beams on elastic foundations and comparison with test data for deflection and proportional limit stresses of nailed joints under lateral load. A simple theoretical expression is derived which relates single shear load and joint slip for a laterally loaded, smooth round nail in a

Combinations of Lateral Load-Resisting Systems

2015
This chapter presents examples in which different lateral load-resisting systems occur in the same direction, in orthogonal directions, or along the height of a building. At issue is the height limitation for the combined system and the appropriate values of R, Ω o , and C d to use for the system.

Ultimate lateral load resistance of laterally loaded pile

2009
Several methods are available for predicting ultimate lateral load resistance of laterally loaded pile. These methods often produce significantly different ultimate lateral resistance. This makes it difficult to select an appropriate method in designing/predicting ultimate lateral resistance of pile.
