Self-assembling growth of fractal catalysts on fuel cell's electrode.

The research of processes of formation of nickel catalyst as nanodendritic coverings on cermet surface was realized by means of computer simulations. Processes of arising, growing and reconstruction of nickel fractal nanodendrites was investigated, calculation of its physicochemical properties was also given. A new model of the multi-objective cellular automation for computer imitation of the self-organized aggregation of fractal nanodendrites was realized.

[Treatment of abdominal aortic aneurysms in patients older than 70 years of age].

The investigation has shown that patients with the diagnosed abdominal aortic aneurysms must be operated, the age being not considered a contraindication to surgical treatment. Five years survival of the patients after resection of the abdominal aortic aneurysm and its prosthesis does not depend on the age and is higher than 70%, while the expectant management leads to rupture of the aneurysm and death of 70% of the patients. A medical algorithm has been developed allowing reduction of lethality of elderly patients with abdominal aortic aneurysms and less frequency of complications.

[Surgical treatment of atherosclerotic lesions of the terminal part of the aorta and iliac arteries].

The operations of semiclosed endarterecromy of the aortofemoral zone arteries were shown to have a number of advantages over shunting interventions with synthetic transplants. They are quick, not traumatic and have better results of long term patency. However, their application is limited by certain indications.
