Sustainable development strategy of universities

The study hypothesizes that the concept of sustainable development can be a central model for organizing the activities of universities to implement measures to improve social and environmental social development. The paper attempts to systematize the accumulated foreign experience on the activities within the framework of achieving the UNO Sustainable Development Goals. As a result, three models have been highlighted, which makes it possible to classify all the social and environmental activities carried out by the best universities in the world in order to implement the best of them in the activities of Russian universities to increase their competitiveness. The hypothesis of this study is that the concept of sustainable development can be a central model for organizing the activities of universities for the implementation measures to improve social and environmental community development. The subject of the study is sustainable development strategies. The object of the study is the leading foreign universities. The methods of scientific cognition used in this study are as follows: dialectical and retrospective analyses, induction and deduction, comparative analysis, summaries and groupings

The effectiveness of combination of 7% hypertonic saline and 0.1% natrii hyaluronas in patients with chronic obstructive pulmonary disease who have suffered a new coronavirus infection

Introduction. New coronavirus infection (COVID-19) contributes to the aggravation of respiratory symptoms in patients with COPD, including affecting the intensity and nature of cough. Hypertonic solution (HS) has a positive effect on the rheological properties of sputum and mucociliary clearance. However, there are no studies in the available literature on the use of HS in patients who have undergone COVID-19.Goal. To evaluate the effect of the combination of 7% hypertonic saline and 0.1% natrii hyaluronas on the intensity and productive nature of cough in patients with COPD who have undergone a new coronavirus infection and the safety of its use in this cohort of patients.Materials and methods. 50 patients with severe COPD in remission who suffered a new coronavirus infection were examined. The rehabilitation stage of treatment was carried out in the conditions of the pulmonology department. From the moment of receiving the last negative PCR result for SARS-CoV-2 to admission to the hospital for rehabilitation, it took from 2 to 3 weeks. The duration of follow-up of patients was 10 days. The patients were divided into two groups: group 1 (n = 25) – patients who received combination of 7% hypertonic saline and 0.1% natrii hyaluronas 7% by inhalation through a nebulizer; group 2 (n = 25) – patients who did not receive combination of 7% hypertonic saline and 0.1% natrii hyaluronas. The severity of cough was assessed (cough severity scale; shortness of breath, cough and sputum scale), clinical and biochemical blood tests, ECG, spirometry.Results. In patients treated with combination of 7% hypertonic saline and 0.1% natrii hyaluronas, a significant decrease in the severity of cough, the amount of sputum was revealed. The tendency to reduce shortness of breath and improve the quality of life is determined. No serious adverse events were detected when using the drug.Conclusions. The use of the combination of 7% hypertonic saline and 0.1% natrii hyaluronas in patients with COPD who have suffered a new coronavirus infection at the rehabilitation stage leads to a decrease in the intensity of cough and improved sputum discharge, which helps to reduce the severity of shortness of breath and improve the quality of life. The use of the drug is safe and does not lead to clinically significant adverse events

Heat-mode excitation in a proximity superconductor

Mesoscopic superconductivity deals with various quasiparticle excitation modes, only one of them -- the charge-mode -- being directly accessible for conductance measurements due to the imbalance in populations of quasi-electron and quasi-hole excitation branches. Other modes carrying heat or even spin, valley etc. currents populate the branches equally and are charge-neutral that makes them much harder to control. This noticeable gap in the experimental studies of mesoscopic non-equilibrium superconductivity can be filled by going beyond the conventional DC transport measurements and exploiting spontaneous current fluctuations. Here, we perform the first experiment of this kind and investigate the transport of heat in an open hybrid device based on a superconductor proximitized InAs nanowire. Using shot noise measurements we observe a novel effect of sub-gap Andreev heat guiding along the superconducting interface and fully characterize it in terms of the thermal conductance on the order of $G_\mathrm{th}\sim e^2/h$, tunable by a back gate voltage. Understanding of the heat-mode also uncovers its implicit signatures in the non-local charge transport. Our experiments open a direct pathway to probe generic neutral excitations in superconducting hybrids.Comment: revised, 20 pages with supplementa

Effect of the GaAsP shell on optical properties of self-catalyzed GaAs nanowires grown on silicon

We realize growth of self-catalyzed core-shell GaAs/GaAsP nanowires (NWs) on Si substrates using molecular-beam epitaxy. Transmission electron microscopy (TEM) of single GaAs/GaAsP NWs confirms their high crystal quality and shows domination of the zinc-blende phase. This is further confirmed in optics of single NWs, studied using cw and time-resolved photoluminescence (PL). A detailed comparison with uncapped GaAs NWs emphasizes the effect of the GaAsP capping in suppressing the non-radiative surface states: significant PL enhancement in the core-shell structures exceeding 2000 times at 10K is observed; in uncapped NWs PL is quenched at 60K whereas single core-shell GaAs/GaAsP NWs exhibit bright emission even at room temperature. From analysis of the PL temperature dependence in both types of NW we are able to determine the main carrier escape mechanisms leading to the PL quench
