The particle shape did not affect the mechanical properties. The fibers showed Alvocidib inhibitor different deformation morphologies at low draw ratios. The CaCO3 composite fibers showed cavities,
which were indicative of low interaction between the polymer and the filler. The OMMT composite fibers showed platelets aligned along the fibers and good polymerfiller interaction. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012″
“Cavernous hemangiomas are rare, benign proliferations of vessels that usually occur at or just after birth. Few cases have been reported in the literature, however, involving the maxilla. We report a rare case of central cavernous hemangioma of the maxilla in an elderly male, review the literature, and discuss treatment options. An algorithm for treatment of all vascular lesions has been developed based on current literature, modem imaging and endovascular technology.
With proper diagnosis, planning and treatment, large vascular lesions can be managed with minimal blood loss and morbidity. This patient was reconstructed to full function utilizing zygomaticus implants and an implant-retained prosthesis. (C) 2009 American Association of Oral and Maxillofacial Surgeons”
“A nanogranular system of multiferroic CoCr(2)O(4) nanoparticles embedded in an antiferromagnetic Cr(2)O(3) matrix has been synthesized through a high-temperature phase segregation route from a Co-doped Cr(2)O(3) matrix. Magnetic studies show that exchange bias fields (H(EB)) accompanying vertical magnetization shifts (M(Shift)) are observed at low temperatures after field cooled from 350 K. The corresponding exchange bias field can be find more as large as 1420 Oe, and the vertical magnetization
shift reaches 0.116 emu/g at 10 K. The exchange bias field decreases with temperature increasing and disappears at T approximate to 70 K, while the coercive field (H(C)) initially increases with the temperature up to 40 K, and this website thereafter, it decreases to zero at 100 K. This exchange bias behavior is discussed in terms of the existence of exchange coupling between the ferrimagnetic CoCr(2)O(4) core and spin glass-like phase at the interfaces.

“In this study, cellulose sulfoacetate (CSA) was produced with cellulose extracted from sugarcane bagasse with sulfuric acid as a catalyst under homogenous conditions so that the derivative could be applied as an additive for mortar of Portland (Cimento Portland de alta resistencia inicial, CPV-ARI) cement. The IR spectra showed that only precipitate C presented the characteristic band of sulfate groups (807 cm(-1)) and was, therefore, the sulfoacetylated derivative. CSA presented a degree of acetylation of 2.70 and a degree of sulfonation of 0.063, and the presence of sulfate groups in the derivative displaced the position of C(6) to a lower field in the C-13-NMR spectrum and influenced reduced viscosity as a function of concentration.
