2. Important Characteristics of TiO2
(1) Photocatalystic Character
- If the light energy is irrigated at TiO2, the catalyst which absorbed the light energy will activate so it oxidize and restore aspirates.
(2) Characteristic of Ultra-hydrophile
- Ultra-hydrophile is the status that befit with the surface of the material such as glass.
For many of Materials, if we drop water, it ma
Airport management, in common with others involved in the operation of elements of the civil air transportation system, are required to take measures that will provide a high level of protection of buildings and equipment (including aircraft), in addition to ensuring the safety and personal security of passengers and staff using the system. This must be done in manner that disturbs the normal ope

1.2 Structure of Planning for Security
Clearly, the subject of security has wide implications that reach far beyond the jurisdictional limits of the airport to central government itself. Planning to meet the needs of a security emergency requires the involvement of a number of organizations, such as:
∎ The airport administration
∎ The operation airlines
∎ The National
