Korozji, jako procesu korzystnego termodynamicznie, nie można zatrzymać, ponieważ metale występują naturalnie w postaci rud tlenkowych lub soli metali. Dla gospodarki jest to niestety proces kapitałochłonny i niepożądany, jednak z zastosowaniem odpowiednich strategii działania ograniczyć jego skalę. Niniejszy przegląd literatury, głównie lat 2018–2020, skupia się na powłokach kompozytowych opar...

Background: Low bone mineral density (BMD) is recognised in individuals with cystic fibrosis (CF) although the pathogenesis remains unclear. The aims of this study were to compare BMD over a broad continuum of Australian individuals with CF with healthy controls and to examine the relationship between BMD and clinical parameters including physical activity, nutrition, and vitamin D levels. Meth...

This study investigated the effects of climate change on the evapotranspiration amount and water balance in the Zayandeh-Rud river basin. Two important weather stations; Isfahan and Chelgerd stations, located in the East and West of the basin respectively, were selected for investigation in this study. The combination of 15 GCM models were created based on the weighting method and three pattern...
