The problem of wd ultrastar dc hc530 the limiting states occurrence in the structures of a vertical steel tank is investigated in this work.To study the SSS of the metal structures of the object, the authors created a numerical model of the RVS-20000 tank in the ANSYS software complex.The model considers the maximum number of elements with their ge
Chatter is an hbl5266ca obstacle for achieving high-quality machining process and high production rate in industries.Chatter is an unstable self-exciting phenomenon that leads to tool wear, poor surface finish, and downgrade the milling operations.A novel active control strategy to attenuate the chatter vibration is proposed.PD/PID controllers in c
Breast cancer is the most prevalent Iranian female malignancy.Breast screening reduces the number of malignant breast diseases.We aimed to assess the results of the pilot breast cancer screening on early detection in female medical staff in Milad Hospital, Tehran, Iran.A cross-sectional study.Female medical staff from Milad Hospital, Tehran, Iran,
