We study bosons loaded in a one-dimensional optical lattice of twofold p-orbital degeneracy at each site. Our numerical simulations find an anti-ferro-orbital p(x)+ip(y), a homogeneous p(x) Mott-insulator phase, and two kinds of superfluid phases distinguished by the orbital order (anti-ferro-orbital and paraorbital). The anti-ferro-orbital order breaks time-reversal symmetry. Experimentally ob...

Stem cell transfection agents have traditionally included lipofectamine, but newer agents include polyethyleneimine-coated magnetic ferro-ferric oxide nanoparticles. This study was done to compare these two methods in transfecting cultured ratmesenchymal stem cells. Magnetic ferro-ferric oxide nanoparticles were coated with polyethyleneimine using co-precipitation of alkali metal ions, forming ...

Um procedimento analítico limpo baseado em extração em ponto nuvem é descrito para a determinação de cobre e ferro em materiais vegetais. Após a digestão da amostra em frascos fechados em forno de microondas, empregando mistura oxidante diluída (HNO 3 + H 2 O 2 ), os íons metálicos foram simultaneamente extraídos como complexos hidrofóbicos formados com 1,2-tiazolilazo-2-naftol (TAN) usando Tri...

this study was aimed to investigate the effects of environmental pollution with heavy metals from ferro-nickel smelter on aminolevulinic acid dehydratase (alad) activity, and to analyze the blood lead level of feral pigeon ( columba livia ) in ferro-nickel smelter courtyard in drenas city, republic of kosovo. for this purpose, twenty specimens of feral pigeon (20 birds, males and females), were...

The previous studies have shown that (a) noncovalent interactions of the ferro-heme fragment of residues 1-38 and apoprotein (1-104) of horse cytochrome c simultaneously and specifically form two isomeric complexes, types I and II resembling the native protein (the redundant residues flexibly protruding from the ordered structure); (b) the type II form but not type I appears to bind to CO; and ...

We present results of ac susceptibility measurements highlighting the presence of thermal hysteresis and phase coexistence across the ferro-to antiferromag-netic transition in various CeFe 2 based pseudobinary systems. These results indicate that the ferro-to antiferromagnetic transition in these systems is first order in nature.
