3 perovskites and observed the perovskite structure as the only phase, with cubic structure, for samples calcined at 800 °C for 4 h. They found out that when increasing the time

The three compositions showed a fully amorphous structure in the ribbons and a predominantly homogeneous amorphous structure with a thickness of up to 10 mm, although some

Fractures were made in all samples. Figure 1 shows fractures of test bars cast from the examined high-aluminium iron in base condition and with the addition of vanadium

The two major shifts observed in the structure of rodent communities took place between the LGM and the HE 1, and between the Bølling and the Allerød (Figs 3 and 4). The

In this work we studied 18 patients with PWS, 20 with AS, 3 with supernu- merary marker chromosomes (SMC), and their parents, by GTG banding and FISH techniques: 14 PWS patients

The critical Ds for the Bt horizon was similar for samples with preserved or deformed structures (Figure 2A and B), however the samples with preserved structure showed a reduction
