Activity in the pallial nerve of knobbed (Busycon carica) and channeled (Busycotypus canaliculatum) whelks recorded during exposure of the osphradium to odorant solutions [PDF]

open access: yes, 2007
Adult horseshoe crabs (Limulus polyphemus) are the preferred bait in the U.S. east coast whelk pot fishery, but their harvest is being restricted because of severe population declines in the Chesapeake and Delaware bays.

Bioluminescence of the heterotrophic dinoflagellate Polykrikos kofoidii Chatton 1914 (Dinophyceae)

open access: yesJournal of Phycology, Volume 62, Issue 2, Page 666-688, April 2026.
Abstract Heterotrophic dinoflagellates are important predators of phytoplankton, and many species produce bioluminescence, which is thought to serve as an antipredator function. The present study investigated the bioluminescence of the heterotrophic dinoflagellate Polykrikos kofoidii, an important predator of toxic and bloom‐forming dinoflagellates ...

FSW varjenje bakra

open access: yes, 2021
V diplomskem delu smo prikazali varjenje dveh bakrenih zlitin Cu-HCP (CW0021A/C10300) in Cu-ETP (CW004A/C11000). Podrobneje smo opisali kemijsko sestavo bakra in opisali njegove fizikalne lastnosti. Na kratko smo podali opis legiranja bakra z drugimi elementi in nastanek zlitin po legiranju.

Optimizing Post Friction Stir Welding Heat Treatment in Dissimilar Friction Stir Welded 6061/AlSi10MgMn Joints for Electrical Vehicle Battery Housing

open access: yesAdvanced Engineering Materials, Volume 28, Issue 5, 4 March 2026.
Microstructural evolution and hardness optimization along the cross‐section of friction stir welded AA6061/AlSi10MgMn joints, for electric vehicle battery housings, were investigated. Postweld aging between 170°C and 220°C enhances hardness uniformity within the nugget zone.
