METHOD OF PREPARING ANHYDRITE BINDER

FIELD: chemistry. SUBSTANCE: invention relates to a method of preparing anhydrite binder and can be used in the industry of construction materials. In the method of preparing anhydrite binder from uncooled acidic wastes from production hydrogen fluoride, involving mixture and neutralisation of the said wastes with a lime-containing agent - self-decomposing ferrochromium slag with simultaneous grinding of the said mixture, a setting agent and a superplasticiser are added in amount of 0.7 and 0.5 wt %, respectively, of the mass of the said wastes while stirring. EFFECT: increased strength of anhydrite binder. 1 tbl.Изобретение относится к способу получения ангидритового вяжущего и может найти применение в промышленности строительных материалов.

Russia in the occupied territories of Ukraine: Policies, strategies and their implementation

Russia pushes for the "Russification" of the territories it occupies in Ukraine. Its policy is aimed at turning them into a military fortress against Ukraine. The declared aim of the economic restoration measures is to make the territories self-sufficient "parts of the Russian Federation". Their "integration" is by far the largest infrastructure project in current Russia. In the absence of tangible military successes, it is also the Kremlin's most important propaganda project. The Kremlin's actions in the occupied territories of Ukraine are like a second front in this war. Studying Russia's occupation policy is important both for understanding the actions of the invader and for developing action plans for the Ukrainian authorities after the end of the war and the liberation of these territories

Analyzing central-line associated bloodstream infection prevention bundles in 22 countries: The results of ID-IRI survey

International audienceBACKGROUND: Because central line-associated bloodstream infections (CLABSIs) are a significant complication of central venous access, it is critical to prevent CLABSIs through the use of central line bundles. The purpose of this study was to take a snapshot of central venous access bundles in various countries. METHODS: The participants in intensive care units (ICUs) completed a questionnaire that included information about the health center, infection control procedures, and central line maintenance. The countries were divided into 2 groups: those with a low or low-middle income and those with an upper-middle or high income. RESULTS: Forty-three participants from 22 countries (46 hospitals, 85 ICUs) responded to the survey. Eight (17.4%) hospitals had no surveillance system for CLABSI. Approximately 7.1 % (n = 6) ICUs had no CLABSI bundle. Twenty ICUs (23.5%) had no dedicated checklist. The percentage of using ultrasonography during catheter insertion, transparent semi-permeable dressings, needleless connectors and single-use sterile pre-filled ready to use 0.9% NaCl were significantly higher in countries with higher and middle-higher income (P < .05). CONCLUSIONS: Our study demonstrated that there are significant differences in the central line bundles between low/low-middle income countries and upper-middle/high-income countries. Additional measures should be taken to address inequity in the management of vascular access in resource-limited countries
