The lateral force images reveal the periodicity of the graphene hexagonal structure allowing the visualization of the lattice symmetries and determination of the crystal orientation. Crystal edges predominantly formed by zigzag or armchair directions were identified. The nature of the edges was confirmed by Raman spectroscopy. (C) 2011 American Institute of Physics.

“A BMN 673 cell line total of 24 cases of hospitalized, laboratory-confirmed Haemophilus influenzae type b (Hib) meningitis were identified through a regional

pediatric bacterial meningitis surveillance system. Each case was matched by age and residence to 4 neighborhood controls. The adjusted vaccine effectiveness for >= 2 doses was 95.8% (95% confidence interval, 67.9%-99.4%). Hib vaccine appears to be highly effective in preventing Hib meningitis in Senegal.”
“The Mg-Al oxide precursor prepared by the calcination of Mg-Al-carbonated ARN-509 research buy layered double hydroxide (LDH) at 500

K for 4 h is used as the host material, 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid (BP) is used as the guest material, BP-intercalated LDH (LDH-BP) is prepared by ion-exchange method. The structure of LDH-BP is characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR), and thermogravimetry and differential thermal analysis (TG-DTA). The thermal stability of PVC/BP, PVC/LDH, PVC/LDH-BP composites, as well as pure PVC is investigated by conventional Congo Red test and dynamic thermal stability analysis in both the open and closed processing environments. According to XRD and FTIR, BP anions have been intercalated into interlayer galleries of LDH. TG-DTA results show that the layer-anionic interaction results in the improvement of the thermal stability of BP. Congo Red tests

indicate that the addition of BP catalyzes the thermal degradation of PVC. A little amount of LDH (such as 1 phr) makes PVC more stable, but excessive addition accelerates Selleckchem HM781-36B the thermal degradation of PVC. The addition of LDH-BP markedly improves the static thermal stability of PVC. The results of dynamic thermal stability tests in both the open and closed processing environments are consistent with that of Congo Red tests. (c) 2011 Wiley Periodicals, Inc.

“Purpose of review

Increasing numbers of women with ovarian cancer are undergoing cytoreductive surgery in reference centres. This review looks at this disease in these women and the different aspects of perioperative clinical management of these patients by the anaesthetic team: preoperative screening, anaesthetic techniques, fluid or blood management or both and prevention and treatment of important complications.
