Radiation Shielding Lead-free Glass Based on Barium-bearing Glass Using Thailand Quartz Sands Krit Won-in1, a, Narin Sirikulrat2,b and Pisutti Dararutana3,c 1Department of Earth Sciences, Faculty of science, Kasetsart University, Bangkok 10900 Thailand 2Department of Physics and Materials Science, Faculty of Science, Chiang Mai University, Chiang Mai 50200 Thailand 3The Royal Thai Army Chemical Department, Phaholyothin Road, Bangkok 10900 Thailand akritwonin@yahoo.com, bmetal.cmu@gmail.com, cpisutti@hotmail.com Keywords: radiation shielding glass, lead-free glass, barium-bearing glass, Thailand quartz sand Abstract.
It can be concluded that the lead-free high refractive index glass that is one of the environmental materials can be used as the gamma radiation shielding glass.
By comparison between the materials, lead glass is the best known for radiation shielding for gamma radiation because of its high density and atomic number [1-3].

The Influence of Rotating Magnetic Field on DCEN MAG Industry Welding based on Properties of Welding Materials Xuming Wang 1, a, Wei Liang 1,b and Suhong Sun 2,c 1 North China Institute of Science and Technology, 065201,China 2 Beijing Institute of Business and Technology, 065202,China awangxuming@ncist.edu.cn, bliangwei@ncist.edu.cn, cfengling123@sina.com Keywords: Rotating magnetic field, DCEN MAG industry welding, Excitation current and frequency, welding spatter.
And its mechanism is researched carefully using high velocity camera.When fixing excitation frequency or excitation current, arc motion behavior, droplet transfer, wire melting coefficient and properties of welding materials are researched.
Nevertheless, wire is cold cathode materials, and cathode drop is much higher than anode.
The properties in welded seam were approach to original materials.

Furthermore, some comfort issues, such as feeling damp, clammy after sweating during driving and skin prickle during the race, and inferior moisture absorbance in suit materials, were also reported [6-7].
Materials and Methods Literature was revised and collected related to the racing suit market, female racing car drivers’ perceptions towards the garment, and consumer needs.
The flow of the liquid moisture through the textiles is caused by fiber-liquid molecular attraction at the surface of the fiber materials, which is mainly determined by the surface tension and effective capillary pathways and pore distribution [31-32].

At the same time, some new and practical knowledge point containing fresh raw materials, processing technology and structural designing should be added periodically to the handout because of the rapid development of modern science and technology.
It is designing by themselves a paper box or carton and choosing the raw materials for it, then printing on the box surface and molding at last.
What are the requirements of the pre-printing on printing materials and equipments?
Processing Technology of Paper Box and Carton is a popular science curriculum to the printing engineering students, in which the packaging designing, raw materials choosing and the packaging goods production were introduced.
It makes us learn more packaging knowledge about packaging materials, packaging process, packaging decoration design.

This study also provided a simply method to endow functionality to the materials in textile industry.
