  • Case Report of Gingivitis Artefacta in Libyan Female Child 5-Years Old 
    Khyria Dhaw Omar (جامعة سرت _ Sirte University, 2019-12-01)
    Gingivitis artefacta is a type of periodontal disease caused by self- inflicted injuries to the gingival tissues. The injuries, most commonly, occur due to picking or scratching of the gingiva with fingernails or any foreign ...
  • Active Control of Surge Compressor System 
    Khalafullah A. Husayn (جامعة سرت _ Sirte University, 2019-12-01)
    Surge is an unstable operating mode of a compression system that occurs at mass flows below the so-called surge line. The instability is characterized by large limit cycle oscillations in compressor flow and pressure rise ...
