Samples of Bi 1.6 Pb 0.4 Sr 1.8 Ba 0.2 Ca 2 Cu 3−x Ni x O 10+δ were prepared by solid-state reaction methods. Mechanical properties (Vickers microhardness, Young modulus, yield strength, fracture toughness and surface energy) by Vickers microhardness measurements have been carried out to examine the effects of Ni substitution. The results showed a deterioration of the mechanical properties with the enhancement of Ni content.

Solid state reaction method was used to prepare samples of Bi 1.6 Pb 0.4 Sr 1.8 Ba 0.2 Ca 2 Cu 2.2 Ni 0.8 O 10+δ. Superconducting and mechanical properties by Vickers microhardness measurements have been carried out to examine the effects of pressure. Electrical measurement demonstrates the best transition temperature was under 0.7 GPa. An improvement of mechanical properties was found when the pressure increases from 0.3 GPa to 0.9 GPa. On the other side an increases of the pressure to 1.1 GPa decrease in the micro hardness, Young modulus and yield strength.

Coherent noise such as ground roll and guided wave is present in the seismic line DE21 (East Diwaniya south eastern Iraq) and it obscures seismic signal and degrades from the quality of data. To attenuate the coherent noise from the shot gather and the Stack of the seismic line, AGORA filter was applied in order to obtain the good signal as the hyperbola shape in shot gather and the reflectors will be clearly to interpret it later. It has given good results and the coherent noise was attenuated in high ratio on all the line. The spectrum analysis is confirmed the effectiveness of AGORA filter to attenuate the coherent noise.

In this paper we are performing Spiking and Gap deconvolution on land 2D data; we are applying on the shot and stack data with operator length (200 ms), while in the gap deconvolution it is used different gap window (16.24 ms). The quality of output data is better than input data, and there is homogeneity in the distribution of frequencies. Also the band width of frequencies is increasing and smoothing specialist in the case of spike deconvolution because it increases the temporal resolution so, it appears for us the inter beds between the layers and this is very important about the interpretation.
