Aronia, as a berry fruit rich in nutrients, represents a suitable raw material for obtaining cold-pressed juices. The chemical composition of aronia indicates the presence of a large amount of polyphenolic compounds and anthocyanins, which contribute to its antioxidant and antimicrobial properties. This study describes the process of producing cold...

In the past few decades, wavelets have found an important place in many fields due to their nature and advantages compared to other algorithms. When the focus is on signal processing, wavelets can be used as an algorithm for de-noising, frequency analysis, feature analysis, etc. The spectrogram is one of the most common visual representations of th...

A significant portion of oil remains trapped in reservoirs after primary and secondary recovery, creating the need for advanced enhanced oil recovery (EOR) techniques. One of the more efficient and environmentally friendly methods is the use of industrial CO₂ in the enhanced oil recovery process (CO₂-EOR). This paper provides an overview of the mec...
