Type C_4 5 case, type C_5 3 cases, type C_6 1 case, all patient were treated with resection of intervertebra disk by anterior route, slotting decompression, fusion with bone grafting, fixation with plate and screws.
Methods 48 cases (Ficat Ⅱ, 27 case; FicatⅢ, 24 cases; FicatIV, 3 cases) were entered into the sick focus of femoral head to be cleared up and decompressed thoroughly by slotting at the neck of femur and operated on with quadrate femoral muscular pedicled bony flap and BMP.
The helical hydraulic sand-blasting slotting technology is an effective method for enhancing oil production by the abrasive waterjet cutting through casing, cement sheath and deep into the formation, which will produce 4 deep helical slots, with the depth of 700-1000 mm, the height of 200-300 mm, and a width of 20-30 mm.
Aimed at the status of idling a lot of condensing units in northeast China, two 200 MW condensing units are transformed into heating units through slotting and extracting steam in Haerbin No. 3 Power Plant. The design, equipment selection and reliability are discussed.
This paper examines various heuristic strategies for solving the demand routing and slotting problem (DRSP) on ring networks.
Assessing Supermarket Product-Line Decisions: The Impact of Slotting Fees
Installation for the heat treatment of high-speed steel slitting and slotting cutters
Deeper defects of the second type cannot be removed.The quality of the slotting mills, particularly the larger sizes, can be improved by reducing the carbide heterogeneity of the original rolled steel.
