Redox and essential metal status in the brain of Wistar rats acutely exposed to a cadmium and lead mixture

open access: yesArhiv za Higijenu Rada i Toksikologiju, 2020
Most Pb and Cd neurotoxicity studies investigate exposure to either of the toxic metals alone, while data on co-exposure are scarce. The aim of our study was to fill that gap by investigating acute combined effects of Pb and Cd on redox and essential ...

Diluted manganese on the bond-centered site in germanium [PDF]

open access: yes, 2010
The functional properties of Mn-doped Ge depend to large extent on the lattice location of the Mn impurities. Here, we present a lattice location study of implanted diluted Mn by means of electron emission channeling.

Protostellar Jet and Outflow in the Collapsing Cloud Core

open access: yes, 2009
We investigate the driving mechanism of outflows and jets in star formation process using resistive MHD nested grid simulations. We found two distinct flows in the collapsing cloud core: Low-velocity outflows (sim 5 km/s) with a wide opening angle ...

Ferromagnetism in Mn doped GaAs due to substitutional-interstitial complexes

open access: yes, 2003
While most calculations on the properties of the ferromagnetic semiconductor GaAs:Mn have focussed on isolated Mn substituting the Ga site (Mn$_{Ga}$), we investigate here whether alternate lattice sites are favored and what the magnetic consequences of ...
