Isomers of Dy 2 O@C 88 and C @C show a strong variation in the type strength Dy?Dy superexchange interactions magnetization relaxation rate.

The linearly polarized x-ray-absorption dichroism at the Dy 3d-4f edge is studied for three dilerent kinds of interfaces: Dy on disordered Si(111),Dy on amorphous Si02, and Dy on polycrystalline Ta. Strong dichroism is observed in all the three interfaces, despite the very different interactions of Dy with the substrates. It is therefore pointed out that the x-ray-absorption dichroism using lin...

There is a growing concern about the use of fisheries-derived proteins in aquaculture. This study was conducted to investigate effect either partially or totally replacing fishmeal (up 15% diet) by inactivated dry yeast product DY-Pro Nile tilapia Oreochromis niloticus diets. The replaced 0% (DY-PRO0), 2% (DY-PRO2), 5% (DY-PRO5), 25% (DY-PRO25), 50% (DY-PRO50), 75% (DY-PRO75) 100% (DY-PRO100) p...

Prion strains are characterized by strain-specific differences in neuropathology but can also differ in incubation period, clinical disease, host-range and tissue tropism. The hyper (HY) and drowsy (DY) strains of hamster-adapted transmissible mink encephalopathy (TME) differ in tissue tropism and susceptibility to infection by extraneural routes of infection. Notably, DY TME is not detected in...

Tomas Lindahl completed his medical studies at Karolinska Institute in 1970. Yet, his work has always been dedicated to unraveling fundamental mechanisms of DNA decay and DNA repair. His research is characterized with groundbreaking discoveries on the instability of our genome, the identification of novel DNA repair activities, the characterization of DNA repair pathways, and the association to...

Bronchial smooth muscle (SM) mesenchymal cell precursors change their shape from round to spread/elongated while undergoing differentiation. Here we show that this change in cell shape induces the expression of laminin (LM) alpha2 chain not present in round mesenchymal cells. LM alpha2 expression is reversible and switched on and off by altering the cell's shape in culture. In comparison, the e...

Rare-earth doped barium zirconate (BaZrO$_3$) ceramics are of interest as proton-conducting and luminescent materials. Here, we report a study dysprosium (Dy) other relevant point defects in BaZrO$_3$ using hybrid density-functional defect calculations. The tetravalent Dy$^{4+}$ is found to be structurally electronically stable at the Zr lattice site (i.e., Dy$_{\rm Zr}^0$), but most often ener...

CaSO4: Dy, P is known for its dosimetric characteristics for a very long time now. In this work we have carried out a comparative study on TL intensity of CaSO4: Dy, P, Ce phosphors using two different wet chemical synthesis routes. Nobody seems to have reported this kind of study on CaSO4: Dy, P, Ce 3+ phosphors and as a result it may be regarded as something new. Phosphors were characterized ...

Bronchial smooth muscle (SM) mesenchymal cell precursors change their shape from round to spread/elongated while undergoing differentiation. Here we show that this change in cell shape induces the expression of laminin (LM) a 2 chain not present in round mesenchymal cells. LM a 2 expression is reversible and switched on and off by altering the cell’s shape in culture. In comparison, the express...
