Measurement of two-particle semi-inclusive rapidity distributions at the CERN ISR
We present data on the semi-inclusive distributions of rapidities of secondary particles produced in pp collisions at very high energies. Our experiment was performed at the CERN Intersecting Storage Rings (IS...

The importance of surface layer on fatigue behavior of a Ti- 6AI- 4V alloy
The effects of precycling and surface removal on the fatigue life and fatigue limit of a Ti-6A1-4V alloy were investigated. It was shown that both the fatigue life and fatigue limit were strongly dependent on ...

Two classes of boundary type cubature formulas with algebraic precision
Here presented are two classes of multivariate numerical integration formulas that make use of merely boundary points as evaluation points. Some special boundary type formulas are constructed as illustrative e...

Partial oxidation of methane over phosphate
Partial oxidation of methane over unpromoted and promoted iron phosphate catalysts was investigated in the temperature range of 873–953 K in a flow reactor. Using XRD and IR techniques, the bulk and surface st...

Magnetic order in rare earth bromates below 0.1 K
Magnetic order inferred from dc susceptibility measurements is reported for Gd, Er, and Yb bromates. No order is seen in Nd bromate at temperatures above ∼6.5 mK. Erbium bromate orders in a fashion outwardly s...

A research on hydrogen cracking in α-Fe
The mechanism of hydrogen cracking in α-Fe has been studied by positron annihilation technique and transmission electron microscopy (TEM). It was revealed that microvoids were promoted by hydrogen-vacancy comp...
