Mitral valve plasty (MVP) is preferred over mitral valve replacement (MVR) for mitral regurgitation in humans because of its favorable effect on quality of life.In small dogs, it is difficult to repair multiple lesions in both leaflets using MVP.Herein, we report a case of severe mitral regurgitation caused by multiple severe lesions in the posteri
Vanadyl In the present paper, results of the research on application of residual fine-grained, carbon-bearing materials as coke substitutes in the shaft process of copper matter smelting are discussed.The addition was introduced into the charge as a component of concentrate-made briquettes, then, its effects on properties of the obtained briquettes
The main advantage of solid bricks over hollow blocks is substantially higher compressive strength.On the other hand, solid bricks have much higher thermal conductivity, which would lead to major heat loss when used for exterior walls.Masonry pillars and walls are usually loaded by compression and/or bending resulting from the eccentricity of verti
Dust is one of the most burdensome hazards found in the environment.It is composed of crushed solids that pose a threat to the health and life of people, machines and machine components.At high concentration levels, it can reduce visibility.All of these negative phenomena occur during the process of underground mining, where dust hazards are common
