The Upper Carboniferous Sandstone at Sao Goncalo do Gurgueia, Northeastern of the Brazil, is notable for its large number of preserved root-like structures. Among these structures it is found rhizoliths, fossils of a root system, containing the origi

The pressure dependent Raman scattering in the potassium molybdenum oxide hydrate crystal, K 2 Mo 2 O 7 ·H 2 O, was measured. The high pressure Raman study showed, that the compound remains in the triclinic structure within the 0.0–3.81 GPa range

Ti and its alloys exhibit combination of unique properties for biomedical applications, however their poor tribo-electrochemical behaviour is a major concern. Therefore, TiN coatings were deposited on cp-Ti (grade 4) by sputtering technique aiming th

Although combining of eCG and hCG administrations is known to enhance LH-like actions, there have been few studies where there was comparison of the effects of treatment of anestrous ewes with eCG and hCG and eCG alone. In Experiment 1, 18 ewes in se

Periodic slab calculations based on density functional theory were performed at the B3LYP level to gain insight into the surfaces of wurtzite GaN nanostructures. The (10 1 ¯ 0) and (11 2 ¯ 0) GaN surfaces are the most thermodynamically stable surfa
