We have indirectly measured the astrophysical S（E） factors for some proton capture reactions and reaction rates for several neutron capture reactions with one nucleon transfer reactions at HI-13 tandem accelerator in recent years. Some of them are compiled into IAEA EXFOR database and JINA REACLIB project, and used in the network calculations of Big Bang nucleosynthesis and type-I X-ray bursts.展开更多

The calculations for the elastic scattering are performed by the phenomenological optical model. The different optical potentials to include breakup effects into the calculations, which are neutron+12C, neutron+10Be and10Be+12C, are described with the aid of the global potentials for neutron interactions and fitted to experimental data for the core and target interaction. Also, the first analysis of the optical model for10 Be on target12 C at 39.1 Me V is done for building the interaction potential of the core and the target for11 Be. For investigating the effects of the spectroscopic factors, obtained factors from the direct capture process using the nuclear level density are compared with the previous cross section and spectroscopic factor results. Obtained results for the elastic cross section reproduce the experimental data very well and show the requirement of including spectroscopic properties such as, spectroscopic factors and density of the excited states, to explain this elastic cross section data.展开更多

Methods: The sperm acrosin activity was tested by the method of BAEE/ ADH Unity and the acrosome reaction by the Triple-stain technique. Results: TNF-α decreased the sperm acrosin activity and acrosome reaction (P<0.01; P<0.01, respectively); it also inhibited the Ca2+-ATPase activity and SOD activity in sperm (P< 0.05; P<0.001, respectively), but increased the NOS activity and the amount of NO in sperm (P<0.001; P<0.001, respectively). While it had a less significant effect on the activity of Na+-K+-ATPase (P>0.05). Conclusion: TNF-α inhibits the sperm acrosin activity and acrosome reaction.展开更多
