Abstract This paper describes buckling modes and stresses of elastic Kelvin open-cell foams subjected to uniaxial compressions. Cubic unit cells and cell aggregates in model foams are analyzed using a homogenization theory. The analysis is performed on the assumption that the struts in foams have a non-uniform distribution of cross-sectional areas as observed experimentally. By performing the analysis based on the uniformity of strut cross-sectional areas, it is shown that the non-uniformity of cross-sectional areas is an important factor for the buckling behavior of open-cell foams.

Abstract Our aim was to compare maternal serum concentrations of interleukin(IL)-1α IL-1β, IL-6 and IL-8 in pregnancies complicated by preterm labor (PTL), with the levels in healthy controls at comparable gestational age, and to determine if these assays have any value in the prediction of early-onset neonatal infection or histological chorioamnionitis. The study population consisted of 65 women with new-onset PTL, and 31 healthy controls. Maternal serum concentrations of IL-6 (8.40 versus 3.30 pg/mL; p = 0.002) and IL-1β (2.20 versus 0.50 pg/mL; p = 0.003) were significantly higher in patients with PTL as compared to… More >

Abstract Our aim was to compare maternal serum concentrations of interleukin(IL)-1α IL-1β, IL-6 and IL-8 in pregnancies complicated by preterm labor (PTL), with the levels in healthy controls at approximately full-term, and to determine if these assays have any value in the prediction of early-onset neonatal infection or histological chorioamnionitis. The study population consisted of 65 women with new-onset PTL, and 31 healthy controls. Maternal serum concentrations of IL-6 (8.40 versus 3.30 pg/mL; p = 0.002) and IL-1β (2.20 versus 0.50 pg/mL; p = 0.003) were significantly higher in patients with PTL as compared to healthy… More >
