“In this work, a numerical Galerkin approach which can handle different boundary conditions in a general manner is presented to study the free vibration of double-walled carbon nanotubes (DWCNTs) modeled as nonlocal Euler beams. The effects of small scale, different boundary conditions, and geometrical parameters on the vibration of DWCNTs are examined in detail. It is also observed from the numerical results that. the higher modes of DWCNT vibration (where the inner and outer nanotubes vibrate out of phase) are dominated by van der Waals interaction

between the inner and outer nanotubes, and small scale effect and boundary conditions are noted to have minimal consequence on the first higher PF-00299804 research buy natural frequency mode of a DWCNT. (C) 2009 American Institute of Physics. [doi:10.1063/1.3239993]“
“Introduction:

Unexpected intraoperative findings are not rare in surgical practice. Meckel’s diverticulum with a mass is one such example. There are only two previously

reported cases of Meckel’s in transplantation, and neither involved Selleckchem CH5183284 pancreas transplant.

Results and discussion:

We present a case report of novel surgical technique using a Meckel’s diverticulectomy site for the duodeno-enterostomy to managing the exocrine secretions of the transplanted pancreas. We also discuss management of Meckel’s diverticulum. The patient tolerated the procedure without complication, and continues to have normal renal and pancreatic function without any gastrointestinal (GI) complaints. The excised Meckel’s diverticulum contained both gastric and pancreatic tissue.

Conclusion:

Although uncertainty about the best management practices exists in the general surgery patient population, given the potential complications that may arise from Meckel’s diverticulum, in transplant patients the Meckel’s should be removed when encountered. The point

of excision can safely be incorporated into other intestinal anastomoses.”
“The present paper deals with the synthesis and characterization of ZnO nanoparticles obtained by coprecipitation method at three different pH conditions. Samples characterizations aimed at understanding OICR-9429 molecular weight their spectroscopic properties are carried out using a variety of experimental techniques. X-ray diffraction and transmission electron microscopic studies show significant increase in the particle size of the synthesized ZnO nanoparticles ranging from 3-40 nm with increasing pH values. Absorption spectra show particle size dependent blueshift in the energy band, which may be ascribed to quantum confinement effect. Fourier transform infrared (FTIR) spectroscopy reveals enhancement in the surface defects of the synthesized ZnO nanoparticles with increasing pH values.
