Essai de la fluméthrine pour le contrôle de la tique Amblyomma variegatum dans un élevage bovin en Guadeloupe

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1987
Une expérimentation a été conduite dans un élevage de Guadeloupe pour estimer l'efficacité et la rèmanence d'un pyrèthre, la fluméthrine, administrée en bain, en aspersion et en dépôt dorsal ("Pour-on") sur la tique Amblyomma variegatum. L'efficacité est

Paleomagnetic Constraint of the Brunhes Age Sedimentary Record From Lake Junín, Peru

open access: yesFrontiers in Earth Science, 2020
Normalized remanence, a proxy for relative geomagnetic paleointensity, along with radiocarbon and U-Th age constraints, facilitates the generation of a well-constrained chronology for sediments recovered during International Continental Scientific ...

Analysis of Passive Shielding Performance Stability in Hybrid Magnetic Shielding Devices

open access: yesApplied Sciences
In hybrid active–passive magnetic shielding systems, active compensation coils are used to suppress residual magnetic fields inside the shield. However, due to the intrinsic hysteresis of high-permeability materials, the compensation fields inevitably ...

Bulk Mn-Al-C permanent magnets prepared by various techniques

open access: yesAIP Advances, 2016
Bulk Mn-Al-C magnets have been prepared by hot-compaction, microwave sintering and hot-deformation. Powders of Mn53.5Al44.5C2 alloy in the ε-phase produced by high energy ball milling have been used as precursor for the hot-compacted and microwave ...

The Wonder Years: Nostalgia, memory and pastness in television credits

open access: yesAlphaville: Journal of Film and Screen Media, 2017
This article explores the various manifestations of analogue video in digital culture. Introducing the framing concept of an aesthetics of remanence, it argues that the “society of the spectacle” (Debord) has entered an age of retrospectacle, a dominant ...

Oriented Magnetite Inclusions in Plagioclase: Implications for the Anisotropy of Magnetic Remanence

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Micron to sub‐micron sized ferromagnetic inclusions in rock forming silicate minerals may give rise to particularly stable remanent magnetizations. When a population of inclusions have a preferred crystallographic or shape orientation in a rock, the ...
