Electronic and magnetic properties of Mn-doped BeSiAs(2) and BeGeAs(2) compounds.

The structural, electronic and magnetic properties of BeSiAs(2) and BeGeAs(2) chalcopyrite ternary compounds doped with manganese were investigated by means of ab initio calculations. It was found that substitution of Be atoms by Mn increases the lattice constants of both compounds that provide acceptable mismatch with conventional Si, Ge and GaAs substrates. In spite of the increase of the spin polarization upon doping, both compounds possess antiferromagnetic (AFM) ordering with the impurity in the group II position whereas ferromagnetic (FM) ordering is obtained in the case of an impurity in the group IV position.

[A method of suturing the operation wound in patients with obesity].

A method of multistoried closing the wound with the help of 2-4 adapting horizontal mattress sutures onto the subcutaneous fatty tissue and one suture onto the skin was used in 58 patients with the III degree of obesity for suturing the postoperative wound in the area of the frontal abdominal wall. No specific complications resulting from the used technique of suturing the wound were noted. Long-term results of treatment showed a good cosmetic effect.

[A model of a long functioning drainage catheter].

The model of a long functioning tube was used in 98 patients with abscesses, phlegmons, suppurating hematomas and diffuse purulent peritonitis. The tube had a purifying device in its lumen as a small bead used for permanent destruction of the fibrin clot in the tube lumen in the postoperative period. It allowed maintenance of its patency for the limitless duration.

[Surgical correction of flatfoot].

The article presents results of treatment of 76 patients with transverse platypodia and the outward aberration of the first toe. In 55 of the patients (72.4%) plasty of the transverse fornix of the foot either with a vascular prosthesis or with a lavsan band was fulfilled parallel with the clinoid resection of the head of the first metatarsus.

[Combined treatment of purulent-necrotic lesions of lower extremities in diabetic patients].

Combined treatment of pyonecrotic focus and purulent see pages on foot by means of permanent abacterial medium creation was performed in 38 patients with decompensated diabetic ischemia of lower extremities. 2% boric acid was used as antiseptic (affected foot was immersed in the solution). Local use of this medium during 7-10 days with sodium succinate and other modern drugs administration permits to decrease lethality to 7.
