Previous chapters have dealt with either a pure normal, or direct, stress (i.e. tension or compression), or a pure shear stress. In many instances, however, both direct and shear stresses are brought into play, and the resultant stress across any section will be neither normal nor ...
reports experimental observations evidencing that the intermetallic compound phase interfaced with Cu in the Al-Cu diffusion couple is most likely α-CuAl phase, not γ-CuAlphase as previously assumed, and that its growth to a critical thickness may result in interface failure by stress-driven ...
The waste material was leached before and after thermal treatment. Concentrations of metals in the eluates were compared with drinking water as well as landfilling (dumping) standards. The results show that the slag, obtained after melting the galvanic sludge, is the only environmentally agreeable ...
In practice, pristine strain/stress allowables are knocked down by semi-empirical factors which allow the creation of damage tolerant designs by accounting for such properties as Compression After Impact (CAI), Tension After Impact (TAI) and Shear After Impact (SAI). Show abstract Vascular self-...
On the basis of the research on stress transfer of flyash piles, the distribution law of frictional resistance is analysed, and with the help of the Mindlin solution and the assumption of the simplified distribution form of frictional resistance, a formula is derived for calculating the additional...
using an optimization algorithm via comparison between experimentally measured stress vs. time data and their counterparts computed by the models. The findings show that the new model not only gives results that are more accurate but also the predicted parameters have more physical significance than ...
2000). The NMR interaction parameters were accurately deduced from the very clean lineshapes recorded for these compounds, and show a linear relationship between χQ and the shear strain ψ as defined in Equation (8.3). This relationship, shown in Figure 8.31A, has the equation Figure 8.31....

and efflux of aromatic compounds; thus, in addition to controlling influx and efflux, the transporter system also forms part of stress tolerance mechanisms through excreting toxic metabolites. This review discusses significant advancements in our understanding of the nature and identity of thebacterial me...
Moreover, compound weather and climate events encourage cascading social processes, with high-impact events creating further socio-cultural, economic/financial, and political effects, as well as stress to individuals.19 Having to live with more extreme and frequent compound events will be particularly ...
