Coherent backscattering of light from biological tissues.

The angular and temporal distributions of light scattered around the backward direction from biological tissues are measured. An enhancement of scattered light intensity around the backward direction, which is associated with the weak photon localization, is observed. The transport mean free path l(t) and the absorption length l(a) of the light in biological tissue can be obtained from the angu...

Measurement of Backscattering from Rfid Tags

This paper presents a method for measuring signal backscattering from an RFID tag and calculating tag radar cross-section (RCS), which depends on the chip input impedance. We present a derivation of a theoretical formula for RFID tag radar cross-section and an experimental RCS measurement method using a network analyzer connected to an antenna in an anechoic chamber where the tag is also locate...

Effect of heavy metals on natural populations of bacteria from surface microlayers and subsurface water

The effect of the heavy metals copper and cadmium on natural bacterial populations of surface microlayer and subsurface water was investigated. Two parameters, number of colony-forming bacteria and 14C-glucose uptake rate, were evaluated. The 2 natural bacterial populations showed different responses to the heavy metals. Results support the existence of autochthonous bacterioneuston populations...
