A Comparison of Supermassive Black Hole Mass of NGC 4151 Using Different Methods

Ismaeel A. Al-Baidhany; Sami Salman Chiad; Mahmood M. Kareem; Wasmaa A. Jabbar; Tahseen H. Mubarak; Nadir Fadhil Habubi; Ehssan S. Hassan; Mohamed Odda Dawood; Oday Mazin Abdulmunem

Volume 2, Issue 1 , March 2020, , Pages 22-26

  We found a new value of supermassive black hole (SMBH) mass in the middle of type 1 Seyfert, NGC 4151 galaxy. In this Study, the image of NGC 4151 galaxy was deprojected to face-on, using spiral galaxy of face-on, and applied IRAF to calculate the ellipticity and position angle of major-axis.  A ...  Read More

Genetic Polymorphism of Toll-Like Receptor 4 Thr399Ile Variant in Iraqi Kurdish Population: Sulaymaniyah Province

Sherko S Niranji

Volume 2, Issue 1 , March 2020, , Pages 32-36

  Toll-like receptors (TLRs), encoded by innate immune genes, functions to detect microbial ligands. Studies found that polymorphisms in TLR genes among populations are associated with diseases. Among the classes of TLRs, TLR-4 is important for exploring bacterial lipopolysaccharide. TLR-4 Thre399Ile is ...  Read More
