The aim of the study is to show how the washing process, while considering the type of washing agent and number of wash cycles, determines the durability of hydrophobic finishes of laminated fabrics. The samples of material were subject to multiple wash cycles in clear water and with the use of two types of washing agents, namely, an ordinary washing powder and a detergent recommended by manufacturers...
Dryland areas are regarded as highly sensitive to climatic changes. A positive relationship between rainfall and environmental factors is often assumed for areas with an average annual rainfall of 100–300 mm. This assumption disregards the fact that a climate change in arid areas is not limited to climatic factors. It is often accompanied by a pronounced spatial variability in surface characteristics...
Głównym celem badań jest analiza zjawiska hydrofobowości w glebie torfowo-murszowej. Badania zostały przeprowadzone w odwodnionych, użytkowanych łąkowo profilach gleby saprowo-murszowej, zlokalizowanych w środkowym Basenie Biebrzy. Przeprowadzono ocenę zwilżalności gleby, wykorzystując test czasu wsiąkania kropli wody (WDPT) i alkoholu (MT). Badania wykazały silną zależność hydrofobowości od uwilgotnienia...
