Gastroesophageal reflux disease associated with diseases of the respiratory tract
The European community of gastroenterologists in 1997 recognized GERB as "illness of the 21st century". Diseases of a respiratory tract take the leading place among all extra esophageal implications of a gastroesophageal reflux disease. Among them bronchial asthma and a chronic obstructive pulmonary disease are the most widespread. The study of the features of the current and modern methods of diagnosing bronchial asthma, obstructive sleep apnea syndrome and chronic obstructive pulmonary disease associated with gastroesophageal reflux disease is of great importance for identifying potential obstacles to effective treatment and preventing an increase in the risk of hospitalizations of patients with this co-morbid pathology. The morbidity of the pathology of the respiratory tract, combined with gastroesophageal reflux disease, is steadily growing. There is a large number of publications concerning the relationship between gastroesophageal reflux disease and diseases of the bronchopulmonary system, but the etiopathogenesis and the cause-and-effect relationship of these diseases remain in question. 1t is interesting to note that the syndrome of obstructive sleep apnea is not included in the list of extra-oesophageal manifestations, both probably and reliably associated with gastroesophageal reflux disease (according to the Montreal Consensus, 2006), but is of great interest to researchers in recent years
Catalytic properties of ZSM-type zeolites formed under different conditions in reactions of conversion of paraffinic and aromatic hydrocarbons
Spectroscopy of nanosized composites silicon-organic polymer/nanoporous silicas
Fluorescence and excitation spectra (T = 5–290 K) of nanosized silicon–organic polymers
poly(di-n-hexylsilane) and poly(methyl(phenyl)silane) incorporated into porous silica materials
MCM-41 and SBA-15 have been studied with varying pore diameter from 2.8 to 10 nm. The controlled
variation of the pore diameter in the wide range (2.8–10 nm) permitted us, for the first
time, to investigate the optical properties of the polymers on their transition from isolated
macromolecules to a film. It is found that this transition depends on polymer type and occurs via
the formation of new spatially independent structures of the polymers not observed in the spectra
of the film, namely, via the formation of disordered and (or) ordered conformations of polymer
chains and clusters
NORMATIVE ORIENTATION OF THE LANGUAGE OF FICTION: LINGUISTIC-AESTHETIC ASPECT
Purpose: The article conducts the study implementation of the normative orientation of the language of fiction: linguistic-aesthetic aspect
Methodology: This is analytical-logical research done by content analysis.
Result: In the article, it is argued that normative orientation of the fiction speech is rather different from that of functional styles in which, as a rule, not only non-literary language elements but also specific phenomena of other styles are not used.
Applications: This research can be used for the universities, teachers and education students.
Novelty/Originality: A number of outstanding scientists such as V.D. Levin, N.A. Meshchersky, N.M. Shansky, N.L. Maksimov, D.N. Shmelev, K.A. Panfilov and others consider the language of fiction as a special type of the literary language which is characterized by aesthetic function and in which the particular peculiarities of all other functional styles can be found as well as non-literary linguistic means of different kinds: colloquial, slang, dialectal, etc
Modelling of the deformation of highly porous metals and alloys under dynamic loading
The study represents the analysis of numerical simulation of the failure of aluminum targets made of highly porous or solid 2024 alloy under dynamic loading. The calculations employed the finite elements method in three-dimensional formulation with the use of proprietary programs. The article presents the results of the numerical simulation of Taylor’s test for the projectile made of highly porous aluminum 2024 alloy at the velocities of 75 to 175 m/s. These results are in a good agreement with the results of the experiments. The peculiarities of the destruction of highly porous aluminum targets are shown
