Strain and correlation of self-organized Ge_(1-x)Mn_x nanocolumns embedded in Ge (001)
, 2010 We report on the structural properties of Ge_(1-x)Mn_x layers grown by molecular beam epitaxy. In these layers, nanocolumns with a high Mn content are embedded in an almost-pure Ge matrix. We have used grazing-incidence X-ray scattering, atomic force and

Short-Term Effects of Cattle Browsing on Tree Sapling Growth in Mountain Wooded Pastures [PDF]
, 2018 Browsing by livestock has been identified as an important factor preventing tree regeneration in wooded pastures. Two field experiments were performed to investigate the effects of cattle browsing on tree sapling growth in a mountain-wooded pasture.
