Through thermodynamic smelting experiments, nonisothermal and isothermal kinetics the effects of CO2–containing gas injection on chromia–bearing vanadiferous titanomagnetite ore were investigated. The experiments at 900 °C, 1000 1100 1200 1300 CO2 concentration 0, 10 vol.%, 20 30 vol.% studied. samples after analyzed through calculations characterized by XRD, XRF, XPS, SEM. results show that si...

1. I n t r o d u c t i o n N-body simulations employing particle-mesh codes have nowadays become a very powerful tool for investigating the dynamics of disc galaxies. In particular, two-dimensional N-body models in which the stars and the cold interstellar gas are treated as two different components have successfully been applied in studies of spiral structure (e.g., Salo 1991; Thomasson 1991)....

In this paper, investigation of the softening behaviour of a supersaturated Al-Mn-Fe-Si alloy during annealing after cold rolling has been carried out. Two different homogenization conditions were considered, of which one gives a condition of a large amount of small pre-existing dispersoids, i.e. providing a significant static Zener drag, while the other gives a condition where both concurrent ...

Removal of astringency by endogenously formed acetaldehyde, achieved by postharvest anaerobic treatment, is of critical importance for many types of persimmon fruit. Although an anaerobic environment accelerates de-astringency, it also has the deleterious effect of promoting excessive softening, reducing shelf life and marketability. Some hypoxia-responsive ethylene response factors (ERFs) part...

Pch313 was isolated as a cDNA whose RNA accumulated during the softening period of peach (Prunus persica L. Batsch) fruit development. To better understand the role of the gene, we compared the amount of pch313-related RNA detected during fruit softening and tissue wounding between cultivars with different softening characteristics. The cultivar that softened faster, "Bailey," had a significant...

Tailoring the intrinsic length-scale effects in bulk metallic glasses (BMGs) via post-heat treatment necessitates a systematic analyzing strategy. Although various achievements were made in the past years to structurally enhance the properties of different BMG alloys, the influence of short-term sub-glass transition annealing on the relaxation kinetics is still not fully covered. Here, we aim f...

Solids deform and fluids flow, but soft glassy materials, such as emulsions, foams, suspensions, and pastes, exhibit an intricate mix of solid- and liquid-like behavior. While much progress has been made to understand their elastic (small strain) and flow (infinite strain) properties, such understanding is lacking for the softening and yielding phenomena that connect these asymptotic regimes. H...

'Taishanzaoxia' fruit rapid softening and dehiscence during ripening stage and this process is very sensitive to endogenous ethylene. In this study, we cloned five ethylene signal transcription factors (ZMdEIL1, ZMdEIL2, ZMdEIL3, ZMdERF1 and ZMdERF2) and one functional gene, ZMdPG1, encoding polygalacturonase that could loose the cell connection which associated with fruit firmness decrease and...
