Social Science.
Though the nuclear-owned countries all claimed that they only put nuclear power for civil use, which means every country will become the potential nuclear weapon possessor. [2]Therefore, we can’t help asking such kind of question: who can guarantee the safety of nuclear materials when transporting them?
Who can ensure that those nuclear materials will not leak to the outside environment or robbed by terrorists?
Anthropocentrism developed by reliance on science and rationalism is a close relationship between them. [5]As science and technology plays an undisputed leading role in human’s material production in a sense, it undoubtedly will result in the form of scientism and technology ruling conception and finally reach into the anthropocentrism in man’s ideology.
Therefore, the rethinking of modern science and technology actually is our self-examination about the attitude towards science. [7] We must be clear that such a result is not the mistake made by science and technology, but the human’s wrong attitudes towards science and technology.

Introduction Composite materials are in great need for particular industries like aircraft, space, marine, automobile sectors.
Machining of composite materials is a challenging task due to their high strength.
However, AWJ cutting of composite laminates requires different cutting parameters for each type of FRP and CFRP materials.

The present work concerns development of porous materials for medicine applications.
The porous materials are recently considered to be the prospective biomaterials for restorative medicine [1,2].
Materials The porous materials were manufactured from the powders of 316L stainless steel with the particle size of 125÷250 µm.
Specification of investigated materials is given in Table 1.
The magnetization of porous materials significantly increased with the step of their plastic deformation.

Therefore, the chemical composition of this material cannot meet the needs of materials.

It has been found in many papers that different inorganic fillers (such as mental[1], fiber[2~4], oxide[5], polymer[6], nanometer materials[7] etc.) show different effect on the friction and wear behaviors of polymer composites.
At first, all the materials were dried for more than 12 hours at 120 in order to remove the moisture.
