This work deals with the use of gamma spectrometry to monitor the fourth generation of sodium fast reactor (SFR) power. Simulation part has shown that power monitoring in short response time and with good accuracy is possible measuring liquid sodium delayed gamma emitters produced in-core. An experimental test is under preparation at French SFR Phénix experimental reactor to validate simulation...

Polyglutamine is a naturally occurring peptide found within several proteins in neuronal cells of the brain, and its aggregation has been implicated in several neurodegenerative diseases, including Huntington's disease. The resulting aggregates have been demonstrated to possess ~-sheet structure, and aggregation has been shown to start with a single misfolded peptide. The current project sought...

Imidacloprid, a relatively long residual neonicotinoid soil insecticide, is often applied to lawns and golf courses in spring for preventive control of root-feeding white grubs. We evaluated effects of such applications on spring parasitism of the overwintered third-instar Japanese beetle, Popillia japonica Newman, by Tiphia vernalis Rohwer, an introduced solitary ectoparasitoid. Natural rates ...

This paper discusses the Target Strength (TS) results offish from in situ measurement at the life sea habitat compared to acoustic model. In situ measurement of fish Selarboops (Oxeye scad) and Megalaspiscordyla (Torpedo scad) have been deployed using Scientific Echo Sounder. Laterally and dorsally X-ray imaged of fish have been deployed to perform fish body and swim bladder morphology. Length,...

Species may become invasive after introduction to a new range because phenotypic traits pre-adapt them to spread and become dominant. In addition, adaptation to novel selection pressures in the introduced range may further increase their potential to become invasive. The diploid Leucanthemum vulgare and the tetraploid L. ircutianum are native to Eurasia and have been introduced to North America...
