A new nano-sized NiMo/TiO2-γ-Al2O3 was prepared as a Hydrodesulphurization catalyst for Iraqi gas oil with sulfur content of 8980 ppm, supplied from Al-Dura Refinery. Sol-gel method was used to prepare TiO2- γ-Al2O3 nano catalyst support with 64% TiO2, 32% Al2O3, Ni-Mo/TiO-γ-Al2O3 catalyst was prepared under vacuum impregnation conditions to loading metals with percentage 3.8 wt.% and 14 wt.% for nickel and molybdenum respectively while the percentage for alumina, and titanium became 21.7, and 58.61 respectively. The synthesized TiO2- γ-Al2O3 nanocomposites and Ni-Mo /TiO2- γ-Al2O3 Nano catalyst were then characterized by XRD, AFM, and BET surface area, SEM, XRF, and FTIR. The performance of the synthesized catalyst for removing sulfur compounds was conducted through the pilot HDS laboratory unit, various temperatures range 275oC to 375°C, LHSV 1 h-1 were studied; moreover, the effect of LHSV 1 to 4 h-1 on the percentage of sulfur removal was also studied at the temperature of the best removal with constant pressure 35 bar and H2/HC ratio 200cm3/200cm3. The sulfur content results generally revealed that there was a substantial decrease at all operating conditions used, while the maximum sulfur removal was 87.75% in gas oil on Ni-Mo/TiO2-γ-Al2O3 catalyst at temperature 375˚C and LHSV 1h-1.

The research was limited to those whom Imam Abu Dawood
described in his Sunan as weak, so this research does not include
narrators who carried descriptions indicating weakness such as
ignorance or others, nor does it include hadiths that the Imam
described as weak.
The number of narrators whom Imam Abu Dawood described as
weak has reached six narrators, and my methodology was to
mention the words of Imam Abu Dawood, then transfer the
sayings of other advanced scholars, as well as the sayings of
Imam Abu Dawood in his other books, if any, to show the extent
of compatibility between these sayings.

activities withen its ambitious nuclear program. It studies the European endeavor to settle
this problem peacefully or to solve it by exerting economic and diplomatic pressures on the
Iranian leadership so, it will give up its nuclear ambitions.
Germany exerts single efforts and others withen the European Troika to follow up
the Iranian nuclear case attempting to prevent Iran from acquiring nuclear weapon which
gives Iran a distinguished regional status. Thus , this situation will lead the current regional
equivalence become unbalanced as well as it is conducive to dangerous consequences , to
