Effect of asymmetric cooling of sessile droplets on orientation of the freezing tip.

Hypothesis: The shape of the "freezing tip" formed by the crystallization of water droplets demonstrated remarkable universality - no dependence on the cooling rate and physico-chemical properties of the substrate has been observed. At the same time, the spatial orientation of the freezing cone may be varied. We hypothesized that the orientation of the freezing tip is determined by the direction of heat flux at the base of the sessile droplet.

Robust icephobic coating based on the spiky fluorinated AlO particles.

Omniphobic and icephobic twin-scale surfaces based on the "urchin"-like fluorinated AlO particles are presented. Combined effect of hierarchical topography and fluorination supplied to the surfaces omniphobic and icephobic properties. The study of the stability of the Cassie wetting state is reported.

[Contamination of surgical wound during tracheal resection depending on the mode of mechanical ventilation].

Objective: To analyze contamination of surgical wound during tracheal resection depending on the mode of mechanical ventilation.

Material And Methods: There were 976 patients. Circular tracheal resection was made in 396 of these patients.

[Etiology, diagnosis and treatment of cicatricial tracheal stenosis].

Development of tracheal surgery was associated with introduction of fundamentally new procedures: two-level reconstruction, redo tracheal resection, tracheal resection with simultaneous dissection of tracheoesophageal fistula. There are combined and staged techniques when tracheal repair or endoscopic interventions are performed as a stage before circular resection of trachea. However, a single algorithm for prevention and correction of postoperative complications is still absent in tracheal surgery.

[Tracheolaryngeal resection for cicatricle stenosis].

Aim: To determine the safest and the most effective surgical treatment of patients with cicatricle stenosis of tracheolaryngeal segment via analysis of different approaches.

Material And Methods: For the period 1963-2015 at Petrovsky Russian Research Center for Surgery and Sechenov First Moscow State Medical University 1128 patients with cicatricle tracheal stenosis have been treated. There were 683 men and 445 women.
