[Treatment of tracheoesophageal fistula and consequences of severe spinal injury].

Modern approaches to intensive care and anesthesiology make it possible to save patients with various severe traumas. Prolonged mechanical ventilation allows stabilizing the patient's status, but can result severe complications including tracheoesophageal fistula. Our patient received severe combined injury after road accident, i.

Short-term effect of COVID-19 lockdowns on atmospheric CO, CH and PM concentrations in urban environment.

The COVID-19 pandemic has changed all areas of human activity as it forced the authorities around the world to enact unprecedented restrictions such as "lockdowns". The low economic activity reduced the anthropogenic impact on the environment, in particular, greenhouse gases and aerosols emissions were decreased. However, the associated change in air quality is difficult to directly observe and quantify, since concentrations of these components in urban areas are affected by many other factors.

A physicochemical model of sorption processes in NO2 passive sampling with air humidity effects.

Aqueous triethanolamine (TEA) solutions are widely used as sorption medium for passive sampling of ambient NO(2), with NO(2) trapped and accumulated as nitrite ion. The results of test measurements of ambient NO(2) concentrations using passive sampling method showed that the simple approach commonly used to describe passive sampling process might lead to substantial systematic errors. Presented in the article is a new physicochemical model of the process of passive sampling of gaseous NO(2), with aqueous TEA solution used as a trapping medium.
