Abstract An aging treatment of UNS S32750 super duplex stainless steel at 1173 K for 1.0 ks produced σ and secondary austenite (γ 2 ) phases in the α γ phase boundary regions. Small amount Mn-Cr oxide MnS complex inclusions were present steel. No pitting was observed during potentiodynamic polarization a small area (200 × 200 µm) without 1 M MgCl 348 K. Because electrode included α, γ, σ, phase...

PCR Conditions: The PCR reaction is carried out in a total volume of 50 /*1 containing approximately 250 ng DNA, 2 units Taq DNA polymerase, 50 pmol of each primer, 200 /M dNTP's, 10 mM Tris-HCl pH 8.3, 50 mM KC1, 1.5 mM MgCl2, 0.001% gelatin. The amplification is performed for 30 cycles with an annealing temperature of 60°C. The amplified product is digested with TaqI and the DNA fragments are...

The application of the photo-Fenton process for the treatment of wastewaters contaminated with diesel oil was investigated. This particular process has been widely studied for the photochemical degradation of highly toxic organic pollutants. Experiments were performed according to a factorial experimental design at two levels and two variables: H(2)O(2) concentration (5-200 mM) and Fe(2+) conce...

Combined QM/MM calculations of an activesite of Cytochrome P450cam have been performed, before and after a binding process of Cytochrome P450cam to Putidaredoxin. The calculations have been carried out for two coordination spheres of the heme active-site of Cytochrome P450cam, namely a 5-coordinated, and a 6coordinated system of this protein having a water molecule as a 6th ligand. An experimen...

One-sided surface charred European beech wood (Fagus sylvatica L.) was studied. Radial and tangential specimens of dimensions 50 × 25 350 mm were one-sided at 200, 250, 300, 350, 400 °C for various times using a contact heating system. Specimens mm3 prepared treatment intensity analysis its effect on wettability. Density profiles the radial determined X-ray densitography with resolution 0.05 mm...
