Матеріали для отоларингологічних стентів повинні мати хорошу міцність на розрив, зносостійкість, біосумісність і певний час деградації. Ця робота стосуэться синтезу поліуретанів на основі різних біодеградабельних сумішей поліолів. Досліджено їхню біодеградабельність і механічні властивості та порівняно з комерційним матеріалом BIOFLEX.
A systematic modern analysis of the state of waste management in the country encourages the search for more rational, efficient and cost-effective ways of processing and recycling solid waste. The inclusion of sewage sludge as a raw material in technologies for processing substrates makes it possible to solve the problems of accumulation and negative environmental impact of this hazardous waste, in addition to the problems of recycling.
Implementation of the proposed approach to bioremediation of oil-contaminated soils provides an intensification of the hydrocarbons degradation process biologically using a digestate as a bio-stimulant, contributes to the production of an ecologically safe substrate, and excludes its toxicity to living organisms due to the degradation of petroleum hydrocarbons.
The system of quality categories, integrated and single indicators was created for the marine ecosystem under the impact of oil production. On the basis of the integral differential approach, a significant and moderate degree of influence has been substantiated for the stages of drilling the well and extracting oil, as well as an insignificant impact for seismic exploration and decommissioning.
