Simulation of Rayleigh-Taylor instability growth rate of laser accelerated plant target. Final report

This report presents the research results for the time point when the Rayleigh-Taylor instability converts to the nonlinear stage as well as the computational results for the interaction of two modes of Rayleigh-Taylor instability when initial perturbations are concentrated at the ablation front (problem (a)) and on the rear side (problem (b)) of the plane target. As was shown in the report for the first phase, for a target of 3 {mu}m thick the existence time of the nonlinear stage is extremely low and does not allow to track the evolution pattern. In it was shown that the plane target with {Delta}{sub 0}=5 {mu}m is more preferable for this goal. Therefore all the computations presented here relate to the target with the indicated thickness. The laser pulse parameters are remained unchanged J{sub L}=10{sup 15} W/cm{sup 2}, {lambda}=0.35 {mu}m

Treatment of Pathologic Fracture of the Humeral Diaphysis Using Metal andPolymer Express Endoprosthetic Replacement as an Example of the Accelerated Rehabilitation of Cancer Patients

ABSTRACT. We report a case of treatment of a 60-year-old female patient D. with a metastatic fracture of the upper and middle third of the left humerus. We made a radical removal of the metastasis, which was complicated by pathological fracture of the left humerus. To replace the removed tumor defect we performed metal and polymer endoprosthetic replacement of the left humeral diaphysis using a locking screw system and bone cement (methyl methacrylate). For accelerated recovery and rehabilitation we applied adaptogenic immunomodulator «Vitavis» (Altai elixir) and neutral anolyte (NA). After the removal of the tumor, postoperative wound was treated with neutral anolyte (NA). Dressings also contained neutral anolyte (NA). These drugs were successfully combined with postoperative basic therapy. The patient was discharged from the hospital on the 4th day after surgery. The functional results of the left upper limb are satisfactory
