Opale: Status und Perspektiven
Authors: Marlow Frank , Muldarisnur  , Sharifi Parvin , Brinkmann Rainer , Mendive Cecilia 
Published: August 2009

AbstractDie Schönheit von Opalen beruht auf einer dichten, hochgeordneten Packung von SiO2‐Kugeln mit einem Durchmesser von einigen hundert Nanometern. Solche geordneten Nanostrukturen sind typische Beispiele für so genannte photonische Kristalle, die sowohl durch die bekannten Mikrostrukturierungsmethoden als auch durch Selbstorganisation hergestellt werden können. Opale stehen für den Selbstorganisationszugang zu diesen strukturierten Medien, die zu neuen Materialien in der Photonik, Photokatalyse und anderen Gebieten führen können. Die Selbstorganisation hat viele Arten von Defekten zur Folge, die zu den überraschenden und sehr individuellen Erscheinungsformen natürlicher Opale führen, aber auch Schwierigkeiten bei der technischen Anwendung von Opalsystemen verursachen.
Opals: Status and Prospects
Authors: Marlow Frank , Muldarisnur  , Sharifi Parvin , Brinkmann Rainer , Mendive Cecilia 
Published: August 2009

AbstractThe beauty of opals results from a densely packed, highly ordered arrangement of silica spheres with a diameter of several hundred nanometers. Such ordered nanostructures are typical examples of materials called photonic crystals, which can be formed by known microstructuring methods and by self‐assembly. Opals represent a self‐assembly approach to these structured media; such an approach can lead to novel materials for photonics, photocatalysis, and other areas. Although self‐assembly leads to many types of defects, resulting in the surprising and very individual appearance of natural opals, it causes also difficulties in technological applications of opal systems.
Pulsed electromagnetic fields stimulation affects BMD and local factor production of rats with disuse osteoporosis
Authors: Shen Wei‐Wei , Zhao Jian‐Hua 
Published: August 2009

AbstractPulsed electromagnetic fields (PEMF) have been used widely to treat nonunion fractures and related problems in bone healing, as a biological and physical method. With the use of Helmholtz coils and PEMF stimulators to generate uniform time‐varying electromagnetic fields, the effects of extremely low frequency electromagnetic fields on bone mineral density (BMD) and local factor production in disuse osteoporosis (DOP) rats were investigated. Eighty 4‐month‐old female Sprague Dawley (SD) rats were randomly divided into intact (INT) group, DOP group, calcitonin‐treated (CT) group, and PEMF stimulation group. The right hindlimbs of all the rats were immobilized by tibia‐tail fixation except for those rats in the INT group. Rats in the CT group were injected with calcitonin (2 IU/kg, i.p., once a day) and rats in the PEMF group were irradiated with PEMF immediately postoperative. The BMD, serum transforming growth factor‐beta 1 (TGF‐β1), and interleukin‐6 (IL‐6) concentration of the proximal femur were measured 1, 2, 4, and 8 weeks after treatment. Compared with the CT and DOP groups, the BMD and serum TGF‐β1 concentration in the PEMF group increased significantly after 8 weeks. The IL‐6 concentration in the DOP group was elevated significantly after operation. The PEMF group showed significantly lower IL‐6 level than the DOP group. The results found demonstrate that PEMF stimulation can efficiently suppress bone mass loss. We, therefore, conclude that PEMF may affect bone remodeling process through promoting TGF‐β1 secretion and inhibiting IL‐6 expression. Bioelectromagnetics 31:113–119, 2010. © 2009 Wiley‐Liss, Inc.
‘Real Italians and wogs’: The discursive construction of Italian identity among first generation Italian immigrants in Western Australia
Authors: Sala Emanuela , Dandy Justine , Rapley Mark 
Published: August 2009

AbstractWe explore the discursive construction of Italian identity among a bilingual sample of Italian‐born Western Australians. Focus groups were held with two groups: Italians who had migrated to Australia as children and a group who had migrated as adults. We found intra‐ and inter‐individual differences in identity construction, with much discourse devoted to demonstrating Italian authenticity and negotiating ethnic category boundaries. Shared markers of authenticity included language, heritage and food. The groups varied in their selection of referent groups to make authenticity claims, with the child migrants drawing upon the shared Australian stereotype of ‘wogs’ to construct and authenticate their Italian‐ness. In contrast, adult migrants constructed Italian identity through comparisons with the dominant Australian ethnic group and in relation to a broader ‘migrant’ identity. The findings highlight the fluid and complex nature of ethnic identity and the need for further exploration of how it is constructed in talk. Copyright © 2009 John Wiley & Sons, Ltd.
An Engineering Model of a Disc Pump Stage for Heavy Oil
Authors: Eskin D. 
Published: August 2009

AbstractAn engineering model of a laminar flow in a disc pump stage of simple design is developed and an approximate analytical solution for a flow in the disc rotor obtained. A rough analytical model for the vaneless diffuser is also found. The performance of a disc stage as it depends on the fluid viscosity, the flow rate, and a channel number is analyzed.
Monitoring cascade processes using VSI EWMA control charts
Authors: Yang Su‐Fen , Yu Yi‐Ning 
Published: August 2009

AbstractThe paper considers the variables process control scheme for cascade process. We construct variable sampling interval (VSI) EWMA and EWMA control charts to effectively monitor the input variable and the output variable produced by a cascade process. Numerical analysis results demonstrate that the performance of the VSI control charts is much better than the fixed sampling interval (FSI) control charts in detecting small and median shifts.

Synthetic, Mechanistic, and Theoretical Studies on the Generation of Iridium Hydride Alkylidene and Iridium Hydride Alkene Isomers

AbstractExperimental and theoretical studies on equilibria between iridium hydride alkylidene structures, [(TpMe2)Ir(H){C(CH2R)ArO}] (TpMe2=hydrotris(3,5‐dimethylpyrazolyl)borate; R=H, Me; Ar=substituted C6H4 group), and their corresponding hydride olefin isomers, [(TpMe2)Ir(H){R(H)CC(H)OAr}], have been carried out. Compounds of these types are obtained either by reaction of the unsaturated fragment [(TpMe2)Ir(C6H5)2] with o‐C6H4(OH)CH2R, or with the substituted anisoles 2,6‐Me2C6H3OMe, 2,4,6‐Me3C6H2OMe, and 4‐Br‐2,6‐Me2C6H2OMe. The reactions with the substituted anisoles require not only multiple CH bond activation but also cleavage of the MeOAr bond and the reversible formation of a CC bond (as revealed by 13C labeling studies). Equilibria between the two tautomeric structures of these complexes were achieved by prolonged heating at temperatures between 100 and 140 °C, with interconversion of isomeric complexes requiring inversion of the metal configuration, as well as the expected migratory insertion and hydrogen‐elimination reactions. This proposal is supported by a detailed computational exploration of the mechanism at the quantum mechanics (QM) level in the real system. For all compounds investigated, the equilibria favor the alkylidene structure over the olefinic isomer by a factor of between approximately 1 and 25. Calculations demonstrate that the main reason for this preference is the strong Ir–carbene interactions in the carbene isomers, rather than steric destabilization of the olefinic tautomers.

Published: August 2009

AbstractThe new dinuclear nickel–ruthenium complexes [Ni(xbsms)RuCp(L)][PF6] (H2xbsms=1,2‐bis(4‐mercapto‐3,3‐dimethyl‐2‐thiabutyl)benzene; Cp−=cyclopentadienyl; L=DMSO, CO, PPh3, and PCy3) are reported and are bioinspired mimics of NiFe hydrogenases. These compounds were characterized by X‐ray diffraction techniques and display novel structural motifs. Interestingly, [Ni(xbsms)RuCpCO][PF6] is stereochemically nonrigid in solution and an isomerization mechanism was derived with the help of density functional theory (DFT) calculations. Because of an increased electron density on the metal centers [Eur. J. Inorg. Chem. 2007, 18, 2613–2626] with respect to the previously described [Ni(xbsms)Ru(CO)2Cl2] and [Ni(xbsms)Ru(p‐cymene)Cl]+ complexes, [Ni(xbsms)RuCp(dmso)][PF6] catalyzes hydrogen evolution from Et3NH+ in DMF with an overpotential reduced by 180 mV and thus represents the most efficient NiFe hydrogenase functional mimic. DFT calculations were carried out with several methods to investigate the catalytic cycle and, coupled with electrochemical measurements, allowed a mechanism to be proposed. A terminal or bridging hydride derivative was identified as the active intermediate, with the structure of the bridging form similar to that of the NiC active state of NiFe hydrogenases.
