ISOPROTERENOL STRUCTURE, ANTIOXIDATIVE PROPERTIES, AND INTERACTIONS WITH PROTEINS
Isoprenaline (isoproterenol) is a non-selective β-adrenoreceptor agonist known for its therapeutic effects, which include increased heart rate and cardiac output, bronchodilation, and improved peripheral circulation. Apart from its primary functions in the nervous system and physiological regulation, isoproterenol exhibits antioxidant pr...

THE POSSIBILITY OF USING POLYMER-BASED PHASE CHANGE MATERIALS FOR THERMAL ENERGY STORAGE
Phase change materials (PCM) are attractive energy storage technologies due to their high energy storage density and the ability to reversible absorb and release thermal energy at a nearly constant temperature. Polymers and polymer-based eutectic mixtures are promising PCMs. This study aims to investigate heat properties (melting temperature ...

PSYCHOLOGICAL ASPECTS OF SPATIALITY
The design of space and its evaluation can be examined from the way space is perceived and from its memory production potential. Such psychological notions of spatiality, which primarily concern the perceived and experienced aspect, are most often drawn from the first children's spatial conceptualizations. Analyzing preverbal and precultural ...

RELATIONSHIPS BETWEEN THE STRUCTURE AND MECHANICAL PROPERTIES OF POLYETHYLENE BLOWN FILMS
The production of polyethylene blown films, which are used for the production of packaging, such as different types of bags and pouches, is a very complex process. With this procedure, the molten plastic mass is extruded through a ring tool and forms a thick-walled cylinder. The still heated and softened cylinder expands by blowing air into a...
