THE PRINCIPLES OF INCREASING THE SENSITIVITY OF TRANSISTOR STRUCTURES TO EXTERNAL INFLUENCES

This article discusses a multifunctional sensor based on a field-effect transistor with a p-n-junction. The sensor allows to register temperature, light intensity, pressure with high level of sensitivity. At the same time, ensuring the sensitivity of the structure to external influences is practically solved due to constructive changes. Due to constructive solutions, the proposed sensor based on a field-effect transistor greatly exceeds the similar diode structures in sensitivity

Experience of Surgical Treatment of Comminuted Fractures of the Distal End of the Femur

The incidence of fractures of the distal femur ranges from 6 to 25% of all fractures of the femur, according to different authors. The most severe of these are intertarsal and supracondylar fractures, which account for up to 42% of all hip fractures, of which type C fractures account for up to 50%. The complex anatomical structure of the distal femur, the condition of the bone tissue, and the mechanogenesis of the injury determine the location, nature, and severity of the fracture. In recent decades, there has been an increase in trauma in general and this localisation in particular due to medical disasters. Because these fractures often occur at working age, the proportion of this population in the population is increasing
