Marangoni instability in oblate droplets suspended on a circular frame

Autor: Shishkin, M. A., Kolegov, K. S., Pikin, S. A., Ostrovskii, B. I., Pikina, E. S.

We study theoretically internal flows in a small oblate droplet suspended on the circular frame. Marangoni convection arises due to a vertical temperature gradient across the drop and is driven by the surface tension variations at the free drop inter

Surgical intervention for lung cancer in patients aged 75 and above: potential associations with increased mortality rates—a single-center observational study

Autor: Andrey Kaprin, Oleg Pikin, Andrey Ryabov, Oleg Aleksandrov, Denis Larionov, Airat Garifullin

Publikováno v: Journal of Cardiothoracic Surgery, Vol 19, Iss 1, Pp 1-12 (2024)

Abstract Background Lung cancer, which is diagnosed two to three times more frequently in patients over the age of 70, is a leading cause of cancer-specific mortality. Given the elevated risk of morbidity and mortality, surgical intervention may not

A rare clinical case of malignant ectopic retrosternal goiter of a large size in a patient with aberrant right subclavian artery

Autor: O. V. Pikin, O. A. Alexandrov, V. A. Glushko, A. V. Levshakova

Publikováno v: Сибирский онкологический журнал, Vol 23, Iss 2, Pp 119-125 (2024)

Background. Ectopic goiter accounts for only 0.2 % to 1 % of all mediastinal goiters. The aberrant right subclavian artery (arteria lusoria) is an extremely rare anomaly of the major vessel, with a prevalence not exceeding 0.3 % in the general popula

Publikováno v: Phys. Rev. E v. 106, No. 5, 055105 (2022)

We present theoretical study and numerical simulation of Marangoni convection within ellipsoidal isotropic droplets embedded in free standing smectic films (FSSF). The thermocapillary flows are analyzed for both isotropic droplets spontaneously forme
