Characterization of surface composition on Alloy 22 in neutral chloride solutions

The composition of anodically grown oxide films on Alloy 22, a Ni-Cr-Mo(W) alloy, has been investigated in 5mol l 1 NaCl at room temperature using X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectrometry. For applied potentials up to 0.2 V (vs Ag/AgCl (saturated KCl solution)), a Cr(III) oxide barrier layer develops at the alloy/oxide interface accounting for the exce...

IL 22 ( interleukin 22 )

A22 22..22

Four randomised controlled trials (RCTs) and one RCT metaanalysis are featured in the Journal this month. The latter is a review of trials of newer-generation antidepressants and cognitive–behavioural therapy (CBT) for adolescent depression (Dubicka et al, pp. 433–440). In an area of clinical practice plagued by controversy, the authors of this review were able to contribute the finding that ad...

A22 22..22

Three papers in the Journal this month consider issues related to measuring, understanding and treating mental ill health in childhood. Baron-Cohen et al (pp. 500–509) undertook a study to establish the prevalence of autism-spectrum conditions in Cambridgeshire using two case ascertainment methods. First, a survey of individuals on the Special Educational Needs register and second, a screening ...

The Token Flow Model 22 of 22

Dataflow graphs that are strongly consistent and have finite complete cycles can always be scheduled statically and executed in bounded memory. Some strongly consistent graphs without finite complete cycles can also be executed in bounded memory. We have described a clustering technique that can identify such graphs and construct their schedules. However, some perfectly correct graphs may not f...
