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 ...

INVESTIGATION OF STATIC AND DYNAMIC STRENGTH OF AIR SUSPENSION BELLOWS IN HEAVY VEHICLES
Air suspension bellows is a rubber-based polymer material that needs to be used in heavyduty vehicles. The service life of the rubber and court cloth used as the bellows material changes due to the process. While premature damage to the bellows increases the risk of accidents, frequent replacements cause an increase in costs. In this study, ...

PHYSICOCHEMICAL PROPERTIES OF CREAM CHEESE WITH THE ADDITION OF SELECTED SPICES
This study aimed to examine the influence of adding selected spices on the physicochemical properties of fresh cream cheese. Six different samples of fresh cream cheese were produced in the milk processing plant (mini cheese factory). The first sample was marked as a control, without the addition of spices, and the other five were produced wi...
