Novel polymethoxylsiloxane‐based crosslinking reagent and its in‐situ improvement for thermal and mechanical properties of siloxane elastomer
Authors: Han Yanming , Zhang Junying , Yang Qiaoyun , Shi Ling , Qi Shicheng , Jin Riguang 
Published: December 2007

AbstractPolymethoxylsiloxane (PMOS) with dense pendant silicone‐methoxy groups was synthesized from cyclosiloxane monomers by ring‐opening polymerization and dehydrocoupling reaction. Synthesis reactions were followed by IR spectroscopy and 29Si NMR analyses. PMOS was used as crosslinking reagent for room temperature vulcanized polydimethylsiloxane (PDMS), and the apparent activation energy for crosslink reaction was 3.92 kJ/mol. TEM study shows that many dispersed high crosslink density PMOS phases were formed in siloxane elastomer as well as the PDMS networks, and the crosslink density increased from PDMS networks to PMOS phases gradually, without a clear interface. It was detected that these PMOS phases improved the thermal and mechanical properties of siloxane elastomer significantly because of their in‐situ microscale improvement effect. TG analysis demonstrated that thermal decomposition process of PMOS crosslinked siloxane elastomer was divided into three stages, the second one corresponding to a possible loss of some new structures, and the residual mass at 500°C was 66 wt %. The crosslink density went up as the loading of PMOS increased. Tensile stress and elastic module increased twice and three times, respectively, when the PMOS content increased from 15.1 to 41.6 wt %. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2008
Synthesis, characterization, and UV curing kinetics of hyperbranched polycarbosilane
Authors: Wang Sheng‐Jie , Fan Xiao‐Dong , Kong Jie , Liu Yu‐Yang 
Published: December 2007

AbstractHyperbranched polycarbosilane with allyl end groups was synthesized via hydrosilylation of methyldiallyldilane, and characterized by Fourier transform infrared spectroscopy, 1H, 13C, 29Si nuclear magnetic resonance, and size exclusion chromatography/multiangle laser light scattering. The degree of branching and average number of branches of the resulted polymer determined by 29Si NMR spectroscopy is 0.58 and 0.42, and the exponent α in Mark–Houwink equation is 0.33 based on the relationship between viscosity and molecular weight. UV curing behaviors of the hyperbranched polycarbosilane were investigated using differential scanning photocalorimeter, and the effects of diluent's concentration, light intensity, reaction atmosphere, and temperature on the curing behaviors and kinetics were studied in detail. It was found that curing reaction can be accomplished rapidly under UV irradiation within 40 s both in air and in nitrogen atmosphere if acrylic reactive diluent was employed. The result suggests that it is an effective way to increase the curing reactivity by incorporating acrylic reactive diluents with high UV sensitivity into the polycarbosilane system. © 2007 Wiley Periodicals, Inc.

Published: December 2007

AbstractIn order to define the regulatory elements responsible for the expression of the medfly hsp83 (Cchsp83) gene, we determined the sequence of a genomic region of the gene that included 3,536 bp upstream of the transcription initiation site, the first untranslated exon of 144 bp, a 275‐bp intron, and 516 bp of the second coding exon. Structural analysis of the 5′ flanking region revealed the presence of a typical TATA box, 28 bp upstream of the transcription start site, and seven putative heat shock elements (HSEs) further upstream. The 5′ untranslated region of the Cchsp83 mRNA was found to contain extensive secondary structure in the first 126 nucleotides. We carried out deletion functional analysis of the proximal promoter region (–380/+139) in vivo by germ line transformation using the lacZ as a reporter gene. We found that sequences in the –380/–86 region are essential for the constitutive expression of the Cchsp83 gene. Under normal conditions, the –380/+139 region was able to drive significant levels of transgene expression in all developmental stages of the medfly as well as in the ovaries and testis. In most stages, the temporal expression pattern of the reporter gene was similar to the respective pattern of the endogenous Cchsp83 gene. Although the –380/+139 promoter region contained two putative HSEs, it was found unable to confer any heat‐induced expression in the reporter gene. Arch. Insect Biochem.

Subcultures and sustainability practices: the impact on understanding corporate sustainability
Authors: Linnenluecke Martina K. , Russell Sally V. , Griffiths Andrew 
Published: December 2007

AbstractIn this paper we present findings of how employees from a single organization understand corporate sustainability. Responses from 255 survey participants indicate (1) that differences exist in how employees understand corporate sustainability and (2) that these differences can be partially explained by the presence of organizational subcultures and by differences in employee awareness of the organization's sustainability practices. In particular, findings reveal that employees from a subculture with a stronger emphasis on hierarchical and bureaucratic values emphasize an economic understanding of corporate sustainability. Implications for research and practice are discussed. Copyright © 2007 John Wiley & Sons, Ltd and ERP Environment.

Legendre spectral finite elements for structural dynamics analysis
Authors: Sprague M. A. , Geers T. L. 
Published: December 2007

AbstractSpectral, hierarchical, and h‐type finite elements (FEs) are compared in the context of their application to structural dynamics analysis. The Timoshenko beam, which is the 1‐D analog of Mindlin‐type shell elements, is used for comparison in eigenvalue and transient‐response analyses. A detailed formulation of each method is presented to illustrate clearly their fundamental differences. The principal advantages of spectral FEs over low‐order h‐type elements are (a) far superior accuracy for a fixed number of model degrees of freedom (DOF) and (b) much higher computational efficiency at a fixed accuracy level. The principal advantages over hierarchical p‐type elements are (a) a mass matrix that is inherently diagonal as opposed to full, (b) DOF that pertain directly to nodal displacements and rotations, and (c) more efficient tensor‐product factorization.

Memory performance and dysfunctional cognitions in recent trauma victims and patients with post‐traumatic stress disorder
Authors: Elsesser Karin , Sartory Gudrun 
Published: December 2007

AbstractIn order to investigate whether cognitive dysregulation contributed to memory impairment in trauma patients, recent trauma victims, post‐traumatic stress disorder (PTSD) patients and healthy controls were compared with regard to verbal memory and dysfunctional cognitions. There were no significant group differences with regard to verbal memory. Concerning dysfunctional cognitions, recent trauma victims hardly differed from controls, unlike PTSD patients, who showed more negative appraisal, more dysfunctional thought control strategies and externality than controls. None of them were related to memory performance in the recent trauma group, and there was a negative correlation with distraction strategy in PTSD patients. In recent trauma victims, negative appraisal increased with time since the trauma. Copyright © 2007 John Wiley & Sons, Ltd.

AbstractNew WHO classification has been widely applied in the diagnosis of leukemia. To elucidate the immunophenotype of acute myeloid leukemia (AML) and characterize the correlation among morphological, immunological, cytogenetic, and clinical features, we studied the bone marrow immunophenotypes of 180 AML patients in China by flow cytometry. The results showed that CD34, CD2, CD14, CD19, CD56, and HLA‐DR were correlated with FAB subtypes. Amongst the 180 patients enrolled in this study, 122 cases were also subjected to karyotype analysis by G‐banding technology and abnormal karyotypes were detected in 69 out of 122 patients. Correlation assay showed that t(8;21) was only present in 16 AML‐M2 patients, and strongly associated with the individual or combinational expressions of CD15/CD19/CD34/CD56. As to M3, although lymphoid lineage antigens were observed in a considerable number of patients, they were never detected in t(15;17) positive patients. The expressions of CD22, CD56, and TdT showed significant correlation with the overall presence of abnormal karyotype. Additionally, the expressions of CD4, CD7, CD14, CD56, and TdT were positively correlated with clinical features such as white blood cell count, platelet count, and patient's age. In conclusion, immunophenotype analysis was useful for AML diagnosis and classification. At the same time, the data also suggested that the karyotype abnormalities and clinical features were tightly linked with abnormal antigen expression characteristics in AML patients. As one of the largest correlative study performed in China, the results highlighted the importance of a morphological, immunological, and cytogenetic classification of AML that might constitute a working basis for future studies aimed at a better definition of clinicopathological features and optimal treatment strategy for these leukemias. © 2007 Clinical Cytometry Society
Flow cytometric assessment of platelet aspirin resistance using light scattering
Authors: Won Dong Il , Yang Dong Heon , Kim Dong Hyun , Chae Shung Chull , Suh Jang Soo 
Published: December 2007

AbstractBackground:A simple and reliable assay is needed for the prediction of the clinical efficacy of antiplatelet aspirin therapy. We have devised another method for the evaluation of platelet function and aspirin resistance (AR), via conventional flow cytometry (FCM).Methods:To devise an optimized protocol for the assessment of platelet AR, various analytic variables of FCM were investigated. Using this devised protocol, AR was assessed in healthy subjects as an example.Results:The protocol utilized herein is as follows: citrate‐anticoagulated platelet‐rich plasma was mixed 1:1 with HEPES‐buffered saline in two tubes, one of which is treated with aspirin. During the acquisition of FCM, arachidonate is added to the tube. The response of the aspirin‐treated platelets is then compared with those of nontreated ones on a time/forward scatter plot. In the 61 total subjects, none was identified as aspirin resistant by this assay.Conclusions:Using light scattering, platelet aggregation and aspirin's antiplatelet effects can be readily and cost‐effectively detected. According to this assay, biochemical AR appears to be rare. This new protocol may prove useful in a clinical setting or as a research tool. © 2007 Clinical Cytometry Society
