Allegedly, irreducible mental properties can be causally relevant in virtue of figuring in non-redundant program explanations which convey information not conveyed by explanations in terms of the physical properties that actually do the ‘causal work’. I argue that none of the possible ways to spell out the intuitively plausi... 查看全文

256   Grafting of poly(ethylene terephthalate) fibers with methacrylic acid using benzoyl peroxide Grafting of poly(ethylene terephthalate) fibers with methacrylic acid using benzoyl peroxide    2003 The graft copolymerization of methacrylic acid onto poly(ethylene terephthalate) fibers, by the aid of benzoyl peroxide, have been investigated. The graft yield increased up to 85°C, and then decreased with the further increase in temperature. The maximum graft yield was obtained at benzoyl peroxide concentration of 4.0 × 10−3 mol/L. The increase in the concentration of monomer was found to increase the graft yield. The change in the graft yield was followed by the experiments ca... 查看全文

258   Dynamics of Alkyl Chains in Monolayer-Protected Au and Ag Clusters and Silver Thiolates:  A Comprehensive Quasielastic Neutron Scattering Investigation Dynamics of Alkyl Chains in Monolayer-Protected Au and Ag Clusters and Silver Thiolates:  A Comprehensive Quasielastic Neutron Scattering Investigation T. Pradeep,*† S. Mitra,‡ A. Sreekumaran Nair,† and R. Mukhopadhyay*‡    2004 Temperature-dependent dynamics of monolayer-protected Au and Ag nanoclusters and silver thiolates have been investigated with quasielastic neutron scattering. The simplest motion in these systems is the uniaxial rotation of the chain, which evolves slowly with temperature. While longer chain monolayers (above C8) on Au clusters are rotationally frozen at room temperature, dynamic freedom exists in lower chain lengths. In the superlattice solids of Ag clusters, the dynamics evolve slowly, and at ... 查看全文

264   Massive star-formation rates of γ-ray burst host galaxies: An unobscured view in X-rays Massive star-formation rates of γ-ray burst host galaxies: An unobscured view in X-rays    2004 The hard X-ray (2-10 keV) luminosity of a star-forming galaxy tracks its population of high mass X-ray binaries and is essentially unobscured. It is therefore a practically unbiased measure of star-formation in the host galaxies of γ-ray bursts (GRBs). Using recent and archival observations of GRBs with the XMM-Newton and Chandra X-ray observatories, limits are placed on the underlying X-ray emission from GRB hosts. Useful limits on the current massive star-formation rates (SFRs), unaffect... 查看全文

265   An unusual high-ionization nebula in NGC 55 An unusual high-ionization nebula in NGC 55    2004 We report on the detection of a previously unknown extended low-density nebula of very high temperature and excitation, TR 001507.7-391206, located above the midplane of NGC 55. The nebular emission line spectrum, in which He II is present, is consistent with photoionization by about 3 very hot massive O3 or WR-type stars. There are no indications for shock ionization. The faint blue optical continuum and XMM-Newton EPIC-pn and OM-data also support our assumption that this nebula is not a supern... 查看全文

Our proposed method consists of two components: (a) tracing the Hubble relation using HII galaxies which can be detected up to very large redshifts, z ∼ 4, as an alternative to supernovae type Ia, and (b) measuring the clustering pattern of X-ray selected AGN at a median redshift of ∼ 1. Each component of the method can in itself provide ... 查看全文

Green*†‡    2012 An important class of functional hard/soft hybrid nanocomposites is formed when nanoparticles (NPs) are induced to self-assemble within the structures of ordered A-b-B diblock copolymers (BCPs). Based on their size, NPs will preferentially reside within edge dislocations, defects, which enable the formation of surface structures, islands or holes, in BCP thin films. The islands (and holes), ubiquitous in BCP thin films, coarsen in a manner reminiscent of 2-dimensional phase ordering systems of b... 查看全文

M. Lange,§ Philippe De    2007 The solid-state organization of copolymers based on methylene oxide (MO) units and tetramethylene oxide (T) units, with T unit contents ranging between 0.9 and 10.0 mol %, is investigated by the combined use of solid-state NMR, WAXS, and DSC experiments. In these semicrystalline copolymers, the T units can be viewed as linear defects inserted along linear poly(oxymethylene) chains. As expected, the insertion of T units induces a significant decrease of both crystallinity and crystallite size:? a... 查看全文

270   Comparison of surgical methods in liver transplantation: retrohepatic caval resection with venovenous bypass (VVB) versus piggyback (PB) with VVB versus PB without VVB Comparison of surgical methods in liver transplantation: retrohepatic caval resection with venovenous bypass (VVB) versus piggyback (PB) with VVB versus PB without VVB T. W. Langfitt and H. Handa    2010 Use of piggyback technique (PB) and elimination of venovenous bypass (VVB) have been advocated in adult liver transplantation (LT). However, individual contribution of these two modifications on clinical outcomes has not been fully investigated. We performed a retrospective review of 426 LTs within a 3-year period, when three different surgical techniques were employed per the surgeons’ preference: retrohepatic caval resection with VVB (RCR + VVB) in 104 patients, PB with VVB (PB... 查看全文
