Na autorytarnym kursie

An Authoritarian Course: The Restriction of Civil Rights in Russia after 2012 This article regards the issue of Russian civil rights legislation, which has become very repressive after 2012. It focuses on legal restriction of all political and social activities that are beyond the control of the authorities, in particular the freedom of public meetings. Another goal of the Kremlin's repressive policy is the Internet, which has become the only space for freedom of speech in Russia. The new legislation tries to prevent this by two mechanisms: censorship and self-censorship. The consistent restriction of freedom of speech in Russia proves the growing anxiety of the ruling group, which fears that in the conditions of the deteriorating economic situation, it may lose control over public mood. The analysis of the legislation against civil rights in Russia shows that in recent years the scope of these rights has been constantly reduced. This leads to the conclusion that the main goal of the discussed changes in the law is the complete elimination of independent civic activity perceived as one of the main threats to the authorities.

DIGITAL ECONOMY AS A BASIS OF ECONOMIC SECURITY OF THE COUNTRY

В данной статье рассматриваются особенности функционирования цифровой экономики в современных условиях. В условиях цифровой экономики полное устранение опасности или риска неизбежно влечет за собой отказ от дополнительных возможностей развития экономики. Поэтому при построении системы безопасности необходимо определить приемлемый уровень риска как с точки зрения его управляемости и предсказуемости, так и возможных последствий. This article discusses the features of the functioning of the digital economy in modern conditions. In the digital economy, the complete elimination of danger or risk inevitably entails the rejection of additional opportunities for economic development. Therefore, when building a security system, it is necessary to determine an acceptable level of risk, both in terms of its controllability and predictability, as well as possible consequences.

Relative rotor phasing for multicopter vibratory load minimisation

This study focuses on vibration reduction for quadcopters and octocopters with elastic, two-bladed, fixed-speed, variable-pitch rotors through the use of relative rotor phasing. The study defines phase modes such as a pitch phase mode with relative phasing between the front and aft rotors, a roll phase mode with relative phasing between the left and right rotors, and a differential phase mode with relative phasing between the clockwise and counter-clockwise spinning rotors for both the quadcopter and the octocopter, as well as additional higher harmonic phase modes for the octocopter. Parametric studies on individual phase modes indicate that, for the quadcopter in forward flight, the pitch and roll phase modes can almost entirely eliminate the 2/rev vibratory forces (at the aircraft level), but the 2/rev vibratory moments cannot be minimised at the same time. By simultaneously using multiple phase modes, a Pareto front can be generated and a solution selected based on the relative emphasis on force or moment vibration reduction. For the octocopter, it was observed that individual higher harmonic modes (specifically the 2c or 2s modes) could almost entirely eliminate both the 2/rev vibratory forces and moments, simultaneously. Compared with vibration levels in forward flight that might, on average, be expected if the rotors were randomly phased, a 62% reduction of a composite vibration index can be achieved on a quadcopter, and complete elimination of vibration was achievable on an octocopter, with appropriate rotor phasing.

Catheter ablation for ventricular arrhythmias using remote magnetic navigation in patients with reduced ejection fraction

Objective. Radiofrequency catheter ablation is an effective treatment option for cardiac arrhythmias including complex and ventricular arrhythmias. Remote magnetic catheter navigation (RMN) has been developed as a novel way of approach aiming to improve outcome and reduce complication rate, and reduce radiation exposure for both operator and patient. Our aim was to compare success and complication rate in patients with or without severely reduced left ventricular ejection fraction (LVEF). Methods. We retrospectively analyzed all the patients (n = 98) which have undergone RMN in our center between 2015-2021. No selection criteria for RMN procedure have been applied. All clinical and paraclinical, as well as procedural data were collected. Patients were divided into two groups, with or without severely reduced LVEF ≤ 35%. CARTO system was used for 3D electroanatomic mapping. RMN was done using Niobe ES system and an open-irrigated magnetic ablation catheter. Success rate was defi ned by complete elimination of clinical arrhythmia. Non-inducibility following ablation was assessed in all patients presenting with any type of ventricular arrhythmia other than premature ventricular contractions. Testing for inducibility was done by ventricular programmed pacing with up to four extra-stimuli. The statistical analysis was performed using SPSS software. P-value < 0.05 was considered signifi cant. Results. Successful ablation with complete elimination of the clinical arrhythmia was achieved in 92.3% of the patients with severely reduced LVEF and in 88.1% of patients with LVEF > 35% (p = 0.73). Overall minor complication rate was 2.04% with spontaneous resolution. No major complications were reported. Non-inducibility was achieved in 56.4% of the patients with LVEF ≤ 35% and in 79.2% of the patients with LVEF >35% (p = 0.023). Conclusion. Radiofrequency catheter ablation using RMN is effective and safe regardless of the presence or not of a severely reduced LVEF.

Rationalizing hospital nutrition

The decisive successes in the construction of the USSR, the cultural growth of the masses and the involvement of members of the working family in production, in connection with the complete elimination of unemployment, set before the consumer cooperation the task of gradually switching food supply from individual consumption to public catering, as the first condition for the transition from small, single household to a large, socialized one.

CATHETER-DIRECTED THROMBOLYSIS AS A METHOD OF CHOICE IN THE TREATMENT OF ACUTE THROMBOSIS OF DEEP VEINS OF THE LOWER EXTREMITIES

Summary. Introduction. Acute thrombosis of deep veins (DVT) of the lower extremities is a pathology that requires immediate treatment, but most thrombolytics do not work effectively, except for catheter-directed thrombolysis. Research aim. Rationalization of DVT treatment, determination of the catheter thrombolysis method as the most effective way to eliminate proximal thrombosis of deep veins. The analysis was based on the results of the treatment by different thrombolytic drugs the patients with the given pathology. Results and discussion. According to the analysis the most effective method of DVT treatment is catheter-guided administration of streptokinase, because streptokinase is the most effective anticoagulant, and its local action on the mass of the thrombus allows for complete elimination of the thrombus in a relatively short time without the counter allergic reaction to the infusion of streptokinase. Conclusions. Catheter-directed infusion of streptokinase as a method of treatment of acute thrombosis of the lower extremities has significantly better treatment results compared to other methods of treatment of this pathology.
