Temperature and electron concentration dependences of 1/ noise in HgCdTe - evidence for a mobility fluctuations mechanism.

HgCdTe is a unique material with its bandgap being tunable by temperature, pressure, and cadmium content over a wide range, from 1.6 eV to an inverted bandgap of -0.3 eV.

[Effect of mucolytic therapy on the production of reactive oxygen species in the blood of patients with an exacerbation of chronic obstructive pulmonary disease].

Aim: To study the production of active oxygen forms (AOF) in the blood of patients with an exacerbation of chronic obstructive pulmonary disease (COPD) and the effect of the mycolytic agent Ambroxol on this process.

Subjects And Methods: Fifty-two patients with an exacerbation of COPD were examined. The patients were divided into 2 groups: 1) a study group (n = 25) received conventional therapy (antibiotics, bronchodilators, glucocorticosteroids) and Ambroxol inhalation; 2) a control group (n = 27) had conventional therapy and placebo (saline) inhalation.
