Thickness improvement in hydroforming of a variable diameter tubular component by using wrinkles and preforms
A combination method of beneficial wrinkle and preform shape is proposed to solve the problem of non-uniform thickness distribution during hydroforming of a variable diameter tubular component. The effect of l...

Characterization of the GLP13 gene promoter in Arabidopsis thaliana
In transgenic plants, for many applications it is important that the inserted genes are expressed in a tissue-specific manner. This in turn could help better understanding their roles in plant development. Ger...

The rapid prediction of the modification level of Al-Si alloys by surface tension
Both the theoretical analysis and experiments on Al-Si alloys have shown that a relationship between the surface tension and the modification of Al-Si alloys exists. A new method for the rapid prediction of th...
