DIPOLE ANTENNAS WITH A SECTOR-SHAPED RADIATION PATTERN [PDF]

Radio Physics and Radio Astronomy
Subject and Purpose. The directivity characteristics of a dipole antenna when it is placed above and parallel to a perfectly conducting screen of rectangular shape are considered, aiming to theoretically study dipole antennas with sector-shaped radiation

Effect of physiological age on radiation resistance of some bacteria that are highly radiation resistant [PDF]

Applied and Environmental Microbiology, 1984
Physiological age-dependent variation in radiation resistance was studied for three bacteria that are highly radiation resistant: Micrococcus radiodurans, Micrococcus sp. isolate C-3, and Moraxella sp. isolate 4. Stationary-phase cultures of M. radiodurans and isolate C-3 were much more resistant to gamma radiation than were log-phase cultures.

Are Nanoporous Materials Radiation Resistant?

Nano Letters, 2011
The key to perfect radiation endurance is perfect recovery. Since surfaces are perfect sinks for defects, a porous material with a high surface to volume ratio has the potential to be extremely radiation tolerant, provided it is morphologically stable in a radiation environment. Experiments and computer simulations on nanoscale gold foams reported here

Radiation Resistance: Resurrection by Recombination [PDF]

Current Biology, 2007
Adaptation to extreme desiccation has conferred extraordinary radiation resistance on the bacterium Deinococcus radiodurans. How this organism is able to reconstruct a genome shattered by gamma rays has now been revealed.

The effect of different combinations of boundary conditions on the average radiation efficiency of rectangular plates [PDF]

, 2014
The boundary conditions of a vibrating plate are known to have an influence on its sound radiation for frequencies below the critical frequency. To investigate this effect in a systematic way, the average radiation efficiency and radiated power are ...

Proton pump inhibitors and sensitization of cancer cells to radiation therapy

Frontiers in Oncology, 2022
This review article outlines six molecular pathways that confer resistance of cancer cells to ionizing radiation, and describes how proton pump inhibitors (PPIs) may be used to overcome radioresistance induced by alteration of one or more of these ...

Radiation-induced FAP + fibroblasts are involved in keloid recurrence after radiotherapy

Frontiers in Cell and Developmental Biology, 2022
Background: Keloid scars (KSs), which are composed of abnormal hyperplastic scar tissue, form during skin wound healing due to excessive fibroblast activation and collagen secretion.
