Primary gastric melanoma is an extremely rare disease. Melanoma of upper gastrointestinal tract usually occurs as metastasis from a primary skin tumor in 1 to 4 % of cases. The paper describes a case report of primary gastric melanoma in a female patient who received complex therapy at the State Healthcare Institution Ulyanovsk Regional Clinical Oncology Dispensary.ΠΠ΅ΡΠ²ΠΈΡΠ½Π°Ρ ΠΌΠ΅Π»Π°Π½ΠΎΠΌΠ° ΠΆΠ΅Π»ΡΠ΄ΠΊΠ° ΠΏΡΠ΅Π΄ΡΡΠ°Π²Π»ΡΠ΅Ρ ΡΠΎΠ±ΠΎΠΉ ΡΡΠ΅Π·Π²ΡΡΠ°ΠΉΠ½ΠΎ ΡΠ΅Π΄ΠΊΠΎΠ΅ Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠ΅.

MicroCHP Based on the Brayton Microturbine with the Changed Order of Processes for the energy supply in low-rise housing
For autonomous power supply itβs suggested to use microCHP (micro combined heat and power plant) based on the Brayton microturbine with the changed order of processes (reversed Brighton cycle). The paper presents the characteristic ranges of thermal and electric power of autonomous consumers in various climate zones and thermodynamic calculations for the two types of microturbine. In the first case, the parameters of the turbine unit are set according to the characteristics of modern vehicles turbochargers, in the second based on the parameters of modern gas microturbines. The work of microCHP based on the microturbine with the changed order of processes was considered for both traditional and low-temperature heating systems. The electric power of microCHP ranges from 2 to 15 kW, thermal power - from 45 to 160 kW. The peculiarity of MicroCHP is combustion of fuel at atmospheric pressure, which allows the use of natural gas from low-pressure networks, solid fuel, and garbage. It is concluded that this turbine unit is able to solve the problem of electricity and heat supply to most isolated consumers in various climate zones
