Using CT scanning to quantify the microstructure change due to freezing at various temperatures in highly-cemented clay Open
Deep soil mixing (DSM) has been adopted in cold regions with growing frequency over the past decade. Although there have been studies on the engineering properties of soilcrete (a product of DSM) subject to freezing/thawing (F/T) cycles, t…

High-fat diet impairs male fertility by disrupting Divalent metal transporter 1 and miR-135b in the gut-testis axis Open
Background Obese patients have been found to be susceptible to iron deficiency, and malabsorption of dietary iron is the cause of obesity-related iron deficiency (ORID). Divalent metal transporter 1 (DMT1) and ferroportin (FPN), are two tr…
