Calculations showed that material hardening has a significant influence on the contact pressure distribution along the contact arc.
Introduction Beryllium foils are widely used in modern X-ray equipment as material for X-ray windows [1,2].
Material hardening significantly effects on the contact pressure distribution and on the stress-strain state during cold rolling of thin foils.

Therefore it can be concluded that these materials are also dense.
This method is very usual in ceramic and ceramic based materials [22].

These faults will reduce the instability of  loose materials on both sides of the main channel.
Formation mechanism of  material source  One type of the loose materials is the collapse accumulation which can be called as potentially unstable body.
The other one is the loose materials which left in the debris flow gully in history.We call this loose materials as unstable body.
So under the action of heavy rain, surface water, and earthquake, the loose materials stability becomes poor.
Local collapse which can provide materials for debris flow will occur.

Analysis results show due to improper material selection bars the safety allowance reduction.
Due to the material change, the welding procedure and welding material should be modified accordingly in order to give guidance to the substitute material, and ensure the correctness of welding material and welding procedure at the substitute parts.
The welding procedure department should select welding material according to the material actually used.
Proper piping materials are selected [8].

Carbonaceous materials have been proven as promising adsorbents for denitration and mercury removal.
XRD is useful for characterizing crystalline structure of carbon materials such as polycrystalline graphite structure; however, biomass semi-cokes are highly disordered carbonaceous materials that have a short-range order poly-crystalline structure [14].
It is widely used to explore the structural features of almost all carbonaceous materials [16].

Materials and Methods of Contraception Deeba Khanam Department of Gynecology, Jawahar Lal Nehru Medical College and Hospital, Aligarh Muslim University, Aligarh, India Email: khanamdeeba@gmail.com Keywords: Contraception, fertilization, pregnancy, health hazards, health care system Abstract.
Details of contraceptive remedies were collected from Arabic literature in 10th century in the works of Al-Razi (Rhazes, d 923 or 924 AD, Quintessence of Experience), Al ibn Abbas (d 994 AD, The Royal Book), and Avicenna (Ibn Sina, d 1037 AD.)[3, 4]Nineteen Century marked an era of development of reproductive science as well as contraception.
