The Acoustic Spectrums of the Combustion Process in the IC-Engines

© The Authors, published by EDP Sciences, 2018. The results of the Fourier spectroscopy of the acoustic noise of an internal combustion engine are presented. The sound was recorded using a voice recorders placed near the four-cylinder petrol engine. The engine speed was set to the fixed values from 900 to 3000 rpm. The distinctive characteristics of the periodograms where associated with the certain physical processes in the engine

Features of diagnosis and treatment of hemorrhagic fever with renal syndrome complicated by renal hematoma

Background. The uniqueness of this clinical case is due to the atypical symptom complex of the disease. A description of the same clinical case was not found in the literature, however, taking into account the fact that hemorrhagic fever with renal syndrome, like most other nosologies, is characterized by a polymorphism of clinical manifestations, the authors consider it necessary to describe this clinical case to the circle of specialists. Limited information due to the low incidence of this clinical course of hemorrhagic fever with renal syndrome puts practitioners in front of the difficulties of diagnosis and treatment. Materials and methods. The outpatient card, data of laboratory and instrumental studies were studied. Results. This observation confirms the correctness of expectant management as the basis for successful therapy for the patient. Conclusions. The data obtained indicate that the appointment of therapy aimed at correcting metabolic disorders contributes to the achievement of a favorable result, and immunotherapy is a promising method in the treatment of viral diseases, in particular, hemorrhagic fever with renal syndrome
