(
Qatar University
, 1989 , Article)
Structural evaluation in Ras Budran oil field was achieved by using the state of art geophysical technology, represented by the 3-D seismic data. Integrated together with the borehole geological and geophysical data. The ...
The electrical and optical properties of poly (4-ethylidene-l, 3-cyclopentylene vinylene)
(
Qatar University
, 1989 , Article)
The intrinsic viscosity, electrical conductivity and IR absorbance were measured for the sample of poly (4—ethylidene—1, 3—cyclopentylene vinylene). The sample is strongly oxidized in air. Under vacuum the activation energy ...
