Bacillus subtilis spore preparations are promising probiotics and biocontrol agents, which can be used in plants, animals, and humans. The aim of this work was to optimize the nutritional conditions using a statistical approach for the production of B. subtilis (WHK-Z12) spores. Our preliminary experiments show that corn starch, corn flour, and wheat bran(More)
Spherical Zn2 SiO4 : Eu3+ phosphors were prepared by a Pechini sol-gel process. The microstructure and luminescent properties of the obtained Zn2 SiO4 : Eu3+ particles were well characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and(More)
The cultivation goal of Applied Technology Universities (A.T.U.) is to bring up the production forefront engineer having a good grasp of theoretical basis and skilled technical ability. However culture methods are old. For example graduation examination is writing graduation thesis or project and reply. This method can not reflect students practical(More)
