The magnitude of the peak stress depends on the relative density of foams, the pulse loading intensity, the pulse loading duration as well as the density homogeneity of foam materials.
Introduction Metallic foams are excellent engineering materials with double efficacy in both function and structure.
According to the analysis in this paper, when metallic foams are used as protective materials, the fixed end is attached to the protected man or objects.

Influenced by alkaline chemical fertilizer and some building materials, the soil pH presents a rising tendency.
Materials and Methods Study Area.
The soil pH in UGS was increased in opposition to the soil acidification and it was likely to be influenced by alkaline chemical fertilizer and some building materials, such as lime and Portland cement, according to the further investigation.
