High Temperature Deformation Mechanism in Hierarchical and Single Precipitate Strengthened Ferritic Alloys by In Situ Neutron Diffraction Studies.

The ferritic Fe-Cr-Ni-Al-Ti alloys strengthened by hierarchical-NiTiAl/NiAl or single-NiTiAl precipitates have been developed and received great attentions due to their superior creep resistance, as compared to conventional ferritic steels. Although the significant improvement of the creep resistance is achieved in the hierarchical-precipitate-strengthened ferritic alloy, the in-depth understanding of its high-temperature deformation mechanisms is essential to further optimize the microstructure and mechanical properties, and advance the development of the creep resistant materials. In the present study, in-situ neutron diffraction has been used to investigate the evolution of elastic strain of constitutive phases and their interactions, such as load-transfer/load-relaxation behavior between the precipitate and matrix, during tensile deformation and stress relaxation at 973 K, which provide the key features in understanding the governing deformation mechanisms.

Based on our previous study, no visible effect of ribavirin therapy in improving clinical outcome was observed. Here we have accumulated the sample size to 634, and by performing prospective observation on the clinical progress and laboratory parameters, we found a significantly higher incidence of anemia and hyperamylasemia in patients who received ribavirin therapy in comparison with those who received no therapy.

[Effects of climate change on photosynthesis of Diospyros kaki under different soil moisture conditions].

Taking two-year-old Diospyros kaki as test material, this paper studied the effects of high CO2 concentration (700 micromol x mol(-1)), high temperature (5 degrees C higher than the mean daily temperature); and their combination on the net photosynthesis rate (Pn), evapotranspiration (Tr), stomatal conductance (Gs), water use efficiency (WUE), chlorophyll content, Fv/Fm, and Fv/Fo under different soil moisture conditions, with the ambient air temperature and CO2 concentration (380 micromol x mol(-1)) as the control. Under all test soil moisture conditions, the combination of high CO2 concentration and high temperature decreased the Tr and Gs, but increased the WUE. This combination increased the Pn when the soil moisture content was 75%-85% and 55%-65% of field capacity, but decreased the Pn when the soil moisture content was 35%-45%.
