The fracture surface of modified epoxy resins was also examined by scanning electron microscope, and

it showed typical features of ductile materials. This study provides see more a cost-effective way to reinforce polymers for engineering applications. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 119: 3670-3674, 2011″
“Viscous elongation of glass rods has been investigated to improve procedures for producing parabolic capillaries from straight capillaries for use as intensity concentrating x-ray optical elements. Experiments and simulations have been carried out pulling Corning 7740 borosilicate glass rods in a cylindrical furnace. Simulations were based on one-dimensional and two-dimensional finite difference/element calculations, assuming that deformation occurred by

linear viscous flow and that the temperatures in the glass remained in equilibrium with the temperatures measured along the axis of the furnace. Rates of elongation in experiments were smaller than those in simulations for later stages of the elongation process. Further experimental and analytical investigations ruled out explanations based on increased viscosities caused by structural relaxation or by partial crystallization and showed that the simulations gave incorrect results because they did not incorporate the dependence of local heat transfer processes on the glass rod radius.

“Abdominal fat harvest and augmentation to the maxillofacial region is a relatively inexpensive, safe, BI 6727 cell line and readily available procedure. The use of abdominal fat free transfer has been well documented for cosmetic, trauma, and temporomandibular joint reconstruction. Fat is the closest we have to an ideal filler, it is readily available and inexpensive, it check details is autologous and therefore lacks a host immune response, it is safe and noncarcinogenic, and it is easily acquired

with a minimally invasive procedure. Abdominal fat donor site is the most commonly used owing to ease of access and availability of fat stores. Complications are rare and easily managed in the office. Free abdominal fat harvest is a predictable surgical technique that allows the maxillofacial surgeon access to autologous graft material that is ideal for multiple facial procedures.

“The main objective of this study was to investigate the composition of microcapsules and the degree of curing of melamine-formaldehyde (MF) resin, which formed a shell of microcapsules, by the use of differential dynamic calorimetry (DSC). For this purpose, decane was chosen as core material. The microencapsulation of decane with MF resin was carried out at different temperatures and pH values. The temperature and pH value were kept constant during the process.
