Apart from animal excrement, others organic materials significantly increased N content of HA.
Among different organic materials, only herb residues increased N of FA.
All of the organic materials significantly increased O content of HMi, and apart from herb residues, the N content of HMi in others organic materials were also significantly increased.

Photoluminescence and afterglow behavior of Eu2+, Dy3+ and Eu2+, Sm3+ in Sr3Al2O6 matrix Chao XU, Dian-qing LU School of Science, Huaihai Institute of Technology, Lianyungang, 222005 China E-mail address: xch09@126.com Keywords: Strontium aluminate; Red long afterglow material; Electron trap Abstract: The long afterglow luminescent materials Sr3Al2O6: Eu, Sm and Sr3Al2O6: Eu, Dy (denoted as S1 and S2, respectively) were synthesized via solid-state reaction.
SrCO3(99℅), Al2O3(99℅), Eu2O3(99.99℅), Sm2O3(99.9℅), Dy2O3(99.9℅) and H3BO3(99.5℅) were employed as the raw materials.
The materials were weighted according to the composition of (Sr2.8Eu0.1Re0.1)(Al1.8B0.2)O6 (Re= Dy, Sm).
The raw materials added with proper analytical alcohol were mixed by a magnetic stirring for 2 h, and then dried at 100 °C for 8 h.

A constitutive material law in framework of micromechanical modeling containing comprehensive constitutive equations for the constituent materials is adopted to model the non-linear behavior of the unidirectional layered materials.
The third assumption is a standard specification of time independent materials.

Introduction Unlike the behaviour of homogeneous materials, the abrupt change in properties at the interface is one source of failure of composite materials[1].
A bi-material is per definition two materials perfectly bonded with no specific material parameters describing the interface.
Characterisation of Cracks at Bi-material Interfaces There is a fundamental difference between the analysis and interpretation of the stress intensity factors for interface cracks in bi-materials as compared to cracks in homogeneous materials.
Unlike homogeneous materials, bi-materials exhibit a coupling of tensile and shear effects.
