Radical Hysterectomy for Carcinoma of the Cervix

Radical hysterectomy refers to the removal of the uterus and cervix and, in addition, to the removal of the upper one-half to one-third of the vagina, the parametria and the pelvic lymph nodes. This operation, which is commonly called the Wertheim operation, was actually first described by Clark in the United States and Ries in Germany. Wertheim\u27s original operation for carcinoma of the cervix consisted only of a partial parametrial removal and removal of the upper one-third of the vagina. It did not include pelvic lymphadenectomy or the removal of the lateral portions of the parametria

Vremenski operator kvantnog singularnog oscilatora

The problem of existence of a self-adjoint time operator conjugate to a Hamiltonian with SU(1,1) dynamical symmetry is investigated. In the space spanned by the eigenstates of the generator K3 of the SU(1,1) group, the time operator for the quantum singular harmonic potential of the form ω 2x 2 + g/x2 is constructed explicitly, and shown that it is related to the time-of-arrival operator of Aharonov and Bohm. Our construction is fully algebraic, involving only the generators of the SU(1,1) group.Istražujemo problem postojanja samo-adjungiranog vremenskog operatora koji je konjugiran hamiltonijanu sa SU(1,1) dinamičkom simetrijom. Konstruirali smo eksplicitno vremenski operator za kvantni singularni harmonički potencijal dan sa ω 2x 2 + g/x2 u prostoru na svojstvenim stanjima generatora K3 SU(1,1) grupe, i pokazali da je povezan s Aharonov–Bohmovim operatorom vremena pristizanja. Naša je konstrukcija vremenskog operatora potpuno algebarska i uključuje samo generatore SU(1,1) grupe
