Po zastosowaniu preparatu Termasil u dzieci leczonych z powodu stanów zapalnych dróg oddechowych o etiologii zarówno bakteryjnej, jak i wirusowej, stwierdzono normalizację ciepłoty ciała oraz poprawę samopoczucia. U wszystkich dzieci zaobserwowano dobrą tolerancję preparatu oraz brak objawów ubocznych.
The study of the flow characteristics of the solid-fluid two phase flow in the cutter suction dredger is very important for exploring the slurry formation mechanism and optimizing the operational parameters. In this study, standard k-ε model and Multiple Reference Frame are applied to numerically simulate flow field in and around the cutting system, then with the steady convergent result of the simulation as the initial condition, Discrete Phase Mode is used to solve the particle motion equation by fully coupling the continuous phase and the particles . The influence of suction flow velocity and cutter’s rotating speed on particles suction are analyzed, and effectively suctioned particles numbers are also quantitatively studied. The simulation result shows that the DPM model is able to simulate the movement of particles in and around the cutter suction dredger’s cutting system, in the fluid flow filed velocity vector and pressure distribution on different planes show different characteristics, and under higher suction velocity and lower cutter rotating speed more particles are suctioned into the suction inlet. The results can help better understand flow characteristics of solid-fluid 2-phase-flow of cutter suction dredger’s cutting system, and provide theoretical support for relative system design and operational parameters optimization
To understand the molecular epidemiology and antibiotic resistance of air and clinical isolates of Acinetobacter baumannii, the intensive care unit settings of a hospital in Northern China were surveyed in 2014. Twenty non-duplicate A. baumannii isolates were obtained from patients and five isolates of airborne A. baumannii were obtained from the wards’ corridors. Pulsed field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) were used to analyze the homology relationships of isolates. Resistance and resistance genes were detected by drug susceptibility test and PCR. The results demonstrated that all isolates can be classified into eight PFGE types and four sequence types (ST208, ST195, ST369 and ST530). A pair of isolates from patients (TAaba004) and from the air (TAaba012) that share 100% similarity in PFGE was identified, indicating that air might be a potential and important transmission route for A. baumannii. More than 80% of the isolates were resistant to carbapenems and aminoglycoside antibiotics. Twenty-four isolates, which were resistant to carbapenems, carried the blaOXA-23-like gene. The data indicated that air might be an alternative way for the transmission of A. baumannii. Hospitals should pay more attention to this route, and design new measures accordingly
Climate change has greatly affected the natural habitats of wild plants, especially vulnerable species. However, methods to properly assess priority protected areas (PPAs) that consider climate change have not been established. The distribution of Fraxinus mandshurica in northeast China was assessed, and our goal was to develop model-based strategies for the assessment of PPAs in consideration of climate change. To achieve this goal, we mapped the current and future suitable habitat distributions of F. mandshurica and planned PPAs based on 4 field surveys in northeast China. The models used in this study included a species distribution model (Maxent), systematic conservation planning model (Zonation), and geographic information system (ArcGIS 10.0). To promote sustainable development, the current and future suitable habitats of F. mandshurica must be integrated into the assessment of PPAs; however, the conservation areas of F. mandshurica in existing nature reserves cannot realize the conservation criterion of the Global Strategy for Plant Conservation (GSPC). In the eastern and northeastern regions of northeast China, the suitable habitats are predicted to migrate slightly northwards in the future. The methods used in this study are adequate for the assessment of PPAs and may provide a reference for the conservation and management of vulnerable plants.
