METHODS:Rabbits in traumatic control group and operative group were totally anesthetized with intravenous injection of 10% 1 mL/kg urethan,and then,5# needle was punctured from corneal limbus to anterior chamber to scarify anterior membrane of lens about 5 mm to establish animal models of traumatic cataract of oculus uterque.
The operation adj on matrices arises from the (n - 1)st exterior power functor on modules; the analogous factorization question for matrix constructions arising from other functors is raised, as are several other questions.
The operation number of the stable doubleLR algorithm for normative matrices is only four sevenths of the rationalQR algorithm for real symmetric tridiagonal matrices.
Two-operation homomorphic perfect sharing schemes over rings
Two-operation homomorphic sharing schemes were introduced by Frankel and Desmedt.
They have proved that if the set of keys is a Boolean algebra or a finite field, then there does not exist a two-operation homomorphic sharing scheme.
The hemostatic effect and the healing effect of the modified sponge on the nasal mucosa after nasal surgery were studied.
Liver surgery and transplantation in China: Progress and Challenges
From the limited but available information, we traced the history of developments of liver surgery and transplantation in China.
Liver surgery first started in the late 1950s in China, and it soon flourished mainly because of the great demand in liver surgery and the emergence of a number of giants in liver surgery.
From 1979 to 2005, 274 cirrhosis patients with portal hypertension who underwent the new treatment strategy were followed up to observe different clinical indexes, which were then compared with those of the traditional surgery treatment.
Force microsensor and position microsensor are used to measure surgical information of the force and depth.
The experimental results show that the integration of microsensors for microsurgery robot's end-effector can satisfy the design requirements, and the robotic end trephine can accurately fulfill the surgical task of corneal cutting.
After surgical operation, the operation group undertook bilateral common carotid artery permanent ligation, while the other group did not.
Learning and memory function were measured by Y-maze at 4 h, 8 h, 24 h and 3 d after surgical operation, respectively.
