In the last few years, great attention has Y-27632 nmr been paid to the preparation of iPP/CNT nanocomposites due to their unique thermal and structural properties and potential applications. As the CNT content increases from 0 to 1 wt %, heterogeneous crystal nucleation scales with the CNT surface area. Above 1 wt %, nucleation appears to saturate with the crystallization temperature, reaching approximate to 8 K above that of the neat polymer. Heating scans reveal a complex, two-step, melting process with a small specific heat peak,

first observed approximate to 8 K below a much larger peak for the neat iPP. For iPP/CNT samples, these two features rapidly shift to higher temperatures with increasing phi(w) and then plateau at approximate to 3 K above that in neat iPP for phi(w) 1 wt %. Scan rates affect dramatically differently the neat iPP and its nanocomposites. Transition temperatures shift nonlinearly, while the total transition enthalpy diverges between cooling and heating cycles with decreasing scan rates. These results are interpreted as the CNTs acting as nucleation sites for iPP crystal formation, randomly pinning a crystal structure different than in the neat

iPP and indicating complex transition dynamics. (c) 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013″
“Objective: To determine whether implementation of a metabolic see more monitoring training program (MMTP) in an urban community-based setting improved monitoring in children treated with second-generation antipsychotics (SGAs) and changed prescription rates of SGAs to children.\n\nMethod: The

MMTP was implemented in the Vancouver Coastal Health Child and Youth Mental Health Teams (CYMHTs) on January 1, 2009. A retrospective review of paper charts and electronic records for children seen at the CYMHTs from September 1, 2007, to May 1, 2010, was LXH254 cell line performed to collect the following data: age, sex, foster care, immigrant status, Axis I diagnosis, and medications. In SGA-treated children, anthropometric measurements and blood work completed at baseline and 3, 6, and 12 months were also collected.\n\nResults: Among the 1114 children seen pre-MMTP and 1262 children seen post-MMTP implementation, 174 (15.4%) and 81(6.4%), respectively, were SGA-treated (P < 0.001). Among the SGA-treated children seen at the CYMHTs after MMTP implementation, 38.3% had a copy of the MMTP in their paper chart. Metabolic monitoring increased by up to 40% at baseline (P < 0.01), 20% at 3 (P< 0.01) and 6 months (P< 0.01), and 18% at 12 months after MMTP implementation.\n\nConclusions: Implementation of an MMTP was associated with significantly improved monitoring rates of anthropometric and blood work parameters at baseline and the 3- and 6-month time points, with a trend for improvement at the 12-month time point, in SGA-treated children cared for in urban community mental health clinics.
