CAN PLANT-BASED NATURAL FLAX REPLACE BASALT AND E-GLASS FOR FIBER-REINFORCED POLYMER TUBULAR ENERGY ABSORBERS? A COMPARATIVE STUDY ON QUASI-STATIC AXIAL CRUSHING

Using plant-based natural fibers to substitute glass fibers as reinforcement of composite materials is of particular interest due to their economic, technical, and nitrile gloves in a bucket environmental significance.One potential application of plant-based natural fiber reinforced polymer (FRP) composites is in automotive engineering as crushable

In complex organisms, stem cells are key for tissue maintenance and regeneration.Adult stem cells replenish continuously dividing tissues of the epithelial and connective types, whereas in non-growing muscle and nervous tissues, they are mainly activated upon injury or stress.In addition to replacing deteriorated cells, adult stem cells have to pre

Stages of formation and development of agro-industrial companies - holdings in Ukraine.It was determined that the formation of agro-industrial companies in Ukraine affect the following processes: 1) because of the concentration of land increased production of agricultural products; 2) the use of new technologies in agriculture; 3) integration of pr

Inert gas argon has important applications in the fields of daily life, industrial manufacture and nuclear environmental monitoring.The key to its application is to selectively and efficiently separate and purify Ar from complex gas components.However, the separation of O2 and Ar at normal temperature is full of challenge due to their similar molec
