Epoxy Nanocomposites with Carbon Nanotubes Produced by Floating Catalyst CVD.

Epoxy nanocomposites with float catalysis-produced CNT felt as a filler were prepared. Parameters such as the curing process, glass transition of epoxynanocomposites, structure and morphology of CNT felt, initial epoxy composition, and epoxy nanocomposites were investigated. The influence of CNT felt on curing process in epoxy nanocomposites with different amounts of curing agent was determined.

[The effect of different factors on cardiac rhythm variability in patients with arterial hypertension].

The purpose of this study was to evaluate the influence of different factors, among them left ventricular hypertrophy (LVH) on long-term heart rate variability (HRV) in patients with hypertension. 38 patients with arterial hypertension of different genesis were included in the study. Ischemia was excluded in all the patients by the data of clinical and instrumental methods of investigation.

Influence of left ventricular hypertrophy on heart rate variability in hypertensive patients.

Long-term heart rate variability (HRV) data were obtained from 38 patients with arterial hypertension and 20 healthy persons. New method of HRV analysis based on calculation and estimation of variations of short rhythmogram intervals (SRV) was applied. This method showed that HRV level depends on number of factors.
