Stress Recover yof Synthetic Fibers

Flexural Behavior of Cementitious Composites Reinforced by Synthetic Fibers

The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...

Can the preterm lung recover from perinatal stress?

After birth, adequate lung function is necessary for the successful adaptation of a preterm baby. Both prenatal and postnatal insults and therapeutic interventions have an immediate effect on lung function and gas exchange but also interfere with fetal and neonatal lung development. Prenatal insults like chorioamnionitis and prenatal interventions like maternal glucocorticosteroids interact but...

Stress fibers from two sources

S tress fi bers arise via two distinct pathways, according to Hotulainen and Lappalainen (page 383). Cells contain at least three different types of contractile actin-based stress fi bers. Transverse arcs do not associate with focal adhesions on either end, whereas ventral stress fi bers contact focal adhesions on both ends. Dorsal stress fi bers have one end tied to a focal adhesion on the ven...
