It has been

found that the charge decay shows very different characteristics for the sample with different periods of electric field application. To explain the results a simple trapping and detrapping model based on two trapping levels has been proposed. Qualitative analysis revealed the similar features to those observed experimentally.”
“Genitourinary tract malformations causing hydrops fetalis are rare. The authors report a case of a female delivered H 89 price at 32 weeks gestational age following a prenatal diagnosis of an abdominopelvic cystic mass with hydrops fetalis. The neonate was persistently hypoxic with unstable cardiovascular status and survived only 7 days. At autopsy, a cystic malformation

replaced the vagina and uterus, associated with lower vaginal atresia and anorectal agenesis. The cyst had interfered with the normal process of Mullerian duct fusion, leading to a longitudinal vaginal septum and bifurcation of endocervix, with absent uterus and fallopian tubes. The urinary bladder was compressed by the cyst, resulting in bilateral hydronephrosis. The cyst impeded the inferior vena caval and umbilical venous circulations and impinged upon the thoracic cavity with resultant pulmonary hypoplasia. This malformation, which might be termed “”cystic dysplasia” of the vagina, represents an extreme form of hydrometrocolpos that resulted in hydrops fetalis.”
“Polylactide (PLA) and calcium carbonate (CaCO(3)) were melt blended using a twin-screw extruder. The

morphology of PLA/CaCO(3) composites AZD8055 in vivo was observed by scanning electronic microscopy. The linear and nonlinear shear rheological behaviors of PLA/CaCO(3) melts were investigated by an advanced rheology expended system. The results show that the CaCO(3) particles are evenly dispersed in the PLA matrix. The incorporation of low CaCO(3) content (<20%) causes the reduction of the storage moduli, loss moduli, and dynamic viscosities whereas high CaCO(3) content (>30%) leads to the increase of the storage moduli, loss moduli, and dynamic viscosities. BIIB057 The composites with high CaCO(3) content show pseudo-solid-like behaviors at low frequency. High CaCO(3) content also results in a significant increase of flow activation energy and a dramatic decrease of flow index n, which is in consistent with the more serious shear-thinning tendency of high-filled PLA composites melts. The particular rheological responses might be attributed to the formation and destruction of the percolating network. (C) 2009 wiley Periodicals, Inc. J Appl Polym Sci 114: 1648-1655, 2009″
