The reason may be that the research on the mechanical properties of laminated glass with PVB film has not been conducted in domestic yet, which result in lacking of experimental data to support the material parameters, inaccurate understanding of the mechanical model of the laminated glass and corresponding numerical simulation, The shear resisting is a main factor affected the performance of PVB film, and there hasn’t experimental research on the shear modulus in China yet.

The bed material, in this case - chopped OPF which was loaded on the top of the distributor will swirl due to angular momentum transfer from the hot air.
Material and Method This section discusses the details of the experimental set-up, preparation of the samples (chopped OPF) for batch experiments, measurement and data collection.
The superficial velocity of air was continuously increased until elutriation of material occurs, indicating the maximum operating velocity of the bed.

Introduction Zinc oxide (ZnO) is well known in the scientific community to possess a lot of advantages in its nature, making it as one of the most prominent material for a variety of electronic and opto-electronic applications [1].
Ga, Al, and In can be used as n-type dopant in ZnO, have been generally recognized to influence the optical and also the electrical properties of the materials [2].Other elements of rare earth group, i.e.
This work is expected to provide the science and research information necessary towards the realization of the new enhanced functionality devices through the integration of photonic, electronic and magnetic properties in a single device that will be beneficial for spin light-emitting diodes (LEDs), novel microprocesses and sensitive biological and chemical sensors.Our motivation on ZnO thin film is, therefore, to examine the structural and optical properties obtained through a feasible, toxic free, chemical solution deposition method by manipulating the Gd doping content.
