Aerial oxidation of the novel homocyclic tetratin species [{SnAr2}3SnArBr] (1) [1] (Ar  C6H3Et2-2,6) affords the tritin heterocycle [O{Sn(C6H3Et2-2,6)2}3] (2), which has been crystallographically characterised; 2 is the first reported oxatristannacyclobutane, and the first heterocyclic tin species having both tintin and tinheteroatom bonds.

A politics of the Dreamtime : destructive and regenerative rainbows in Alexis Wright's Carpentaria

A literary criticism of the book "Carpentaria," by Alexis Wright is presented. It discusses the representation of indigenous knowledge in the novel. It outlines the characters and explores the symbolic significance of these characters. It examines the themes of the novel, including the dreamtime mythology as an alternative form of scientific discourse. An overview of the story of the novel is also given.

Social reader : following social networks in the wilds of the blogosphere

The social interactions manifest in blogs by the network of comments left by owners and readers are an under-used resource, both for blog pundits and industry. We present a web-based feed reader that renders these relationships with a graph representation, and enables exploration by displaying people and blogs who are proximate to a user's network. Social Reader is an example of Casual Information Visualization, and aims to help the user understand and explore blog-based social networks in a daily, real-life setting. A six week study of the software involving 20 users confirmed the usefulness of the novel visual display, via a quantitative analysis of use logs, and an exit survey.

Simulation of a novel piezoelectric energy harvester

This paper focuses on a novel piezoelectric energy harvester for nanofiber PVDF to capture energy from vibration environment. A Resembling CMOS(R-CMOS) circuit consisting of two pMOS transistors and two nMOS transistors is presented, which can greatly increase the energy efficiency and reduce the power dissipation tremendously. Meanwhile, the novel harvester supplies smooth direct current. Simulation result of MULTISIM has shown that by using this novel piezoelectric energy harvester the input voltage (5v) can be rectified to be an output voltage (4.24v). The voltage conversion rate of the novel harvester is as high as 84.8% which is much larger than the rate of traditional rectifier circuit. Its potential application is in micro sensors, wireless transducers, and sensor networks.

Boats on the roof of the house: the shadowy flux of alterity

Freud’s ‘The Interpretation of Dreams’ focuses upon the relationship between the signs, in the surface content of the dream, and the operation of thought that produces these signs, in the latent content of the dream. Freud’s analysis is a means for tangling with a discontinuous narrative style because Freud’s analysis provides a methodological approach to the question: how does the novel bear witness to the writer’s subjective consciousness?

China in a book: Victorian representations of the 'celestial kingdom' in William Dalton’s 'The wolf boy of China'

Despite the wealth of material related to China in Victorian and Edwardian children’s literature, relatively few scholarly works have been published on the subject. Critics who have discussed the topic have tended to emphasize the negative discourse and stereotypical images of the Chinese in late nineteenth-century children’s literature. I use the case of William Dalton’s The Wolf Boy of China (1857), one of the earliest full-length Victorian children’s novels set in China, to complicate previous generalizations about negative representations of China and the Chinese and to highlight the unpredictable nature of child readers’ reactions to a text. First, in order to trace the complicated process of how information about the country was disseminated, edited, framed, and translated before reaching Victorian and Edwardian readers, I analyse how Dalton wove fragments from his reading of a large archive of texts on China into his novel.
Although Dalton may have preserved and transmitted some ‘factual’ information about China from his sources, he also transformed material that he read in innovative ways. These are reflected in the more subversive and radical parts of the novel, which are discussed in the second part of the essay. In the final section, I provide examples of historical readers of The Wolf Boy of China to challenge the notion that children passively accept the imperialist messages in books of empire.

Cloning and characterisation of the hint homologue of the Thermophile Thermus thermophilus

Screening of a genomic library of the thermophile Thermus thermophilus revealed a novel thermophilic hint gene, homologues of which are highly conserved in genera from archaea to mammals. Hint belongs to the HIT protein super-family, which contains two broad groups, Fhit, associated with tumour suppression in eukaryotes and Hint with putatitive protein kinase C inhibitory activity. In T. thermophilus the 321bp gene has a GC content of 67% overall and 94.4% in the third nucleotide position, with unusually no thymine as a wobble base. The gene product, a small highly conserved 11996Da predicted soluble cytoplasmic protein, offers an ideal opportunity to investigate thermostabilising amino acid substitutions. Here we report on the characterisation of the novel hint sequence.

Oxygen transfer from an intramolecularly coordinated diaryltellurium oxide to acetonitrile. formation and combined AIM and ELI-D analysis of a novel diaryltellurium acetimidate

The reaction of the intramolecularly coordinated diaryltellurium(IV) oxide (8-Me2NC10H6)2TeO with acetonitrile proceeds with oxygen transfer and gives rise to the formation of the novel zwitterionic diaryltelluronium(IV) acetimidate (8-Me2NC 10H6)2TeNC(O)CH3 (1) in 57% yield. Hydrolysis of 1 with hydrochloric acid affords acetamide and the previously known diarylhydroxytelluronium(IV) chloride [(8-Me2NC 10H6)2Te(OH)]Cl. © 2014 American Chemical Society.

Thermal study of cyclopalladated complexes of the type [Pd-2(dmba)(2)X-2(bpe)] - (X=NO3-, Cl-, N-3(-), NCO-, NCS-; bpe=trans-1,2-bis(4-pyridyl)ethylene)

The synthesis, characterization and thermal analysis of the novel cyclometallated compounds [Pd-2(dmba)(2)Cl-2(mu-bpe)] (1), [Pd-2(dmba)(2)(N-3)(2)(mu-bpe)] (2), [Pd-2(dmba)(2)(NCO)(2)(mu-bpe)] (3), [Pd-2(dmba)(2)(SCN)(2)(mu-bpe)] (4), [Pd-2(dmba)(2)(NO3)(2)(mu-bpe)] (5) (bpe=trans-1,2-bis(4-pyridyl)ethylene; dmba=N,N-dimethylbenzylamine) are described. The thermal stability of [Pd-2(dmba)(2)X-2(mu-bpe)] complexes varies in the sequence 1 > 4 > 3 > 2 > 5. The final residues of the thermal decompositions were characterized as metallic palladium by X-ray powder diffraction.

Isolation and sequence determination of peptides in the venom of the spider wasp (Cyphononyx dorsalis) guided by matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectrometry

Micro-scale (sub-pmol) isolation and sequence determination of three peptides from the venom of the solitary spider wasp Cyphononyx dorsalis is described. We isolated two novel peptides Cd-125 and Cd-146 and a known peptide Thr(6)-bradykinin from only two venom sacs of solitary spider wasp Cyphononyx dorsalis without bioassay-guided fractionation. but instead guided by MALDI-TOF MS. The MALDI-TOF MS analysis of each fraction showed the purity and molecular weight of the components, which led to the isolation of the peptides virtually without loss of sample amount. The sequences of the novel peptides Cd-125 (Asp-Thr-Ala-Arg-Leu-Lys-Trp-His) and Cd-146 (Ser-Glu-Thr-Gly-Asn-Thr-Val-Thr-Val-Lys-Gly-Phe-Ser-Pro-Leu-Arg) were determined by Edman degradation together with mass spectrometry. and finally corroborated by solid-phase synthesis. The known peptide Thr(6)-bradykinin (Arg-Pro-Pro-Gly-Phe-Thr-Pro-Phe-Arg) was identified by comparison with the synthetic authentic specimen. This is the first example for any kinins to be found in Pompilidae wasp venoms. The procedure reported here can be applicable to studies on many other components of solitary wasp venoms with limited sample availability. (C) 2001 Elsevier B.V. Ltd. All rights reserved.

In Vivo Evaluation of the Phenox CRC Mechanical Thrombectomy Device in a Swine Model of Acute Vessel Occlusion

Mechanical thrombectomy in ischemic stroke is of increasing interest as it is a promising strategy for fast and efficient recanalization. Several thrombectomy devices have been introduced to the armentarium of mechanical thrombectomy. Currently, new devices are under development and are continuously added to the neurointerventional tool box. Each device advocated so far has a different design and mechanical properties in terms of thrombus-device interaction. Therefore, a systematic evaluation under standardized conditions in vivo of these new devices is needed. The purpose of this study was to evaluate the efficiency, thrombus-device interaction, and potential complications of the novel Phenox CRC for distal mechanical thrombectomy in vivo. The device was evaluated in an established animal model in the swine. Recanalization rate, thromboembolic events, vasospasm, and complications were assessed. Radiopaque thrombi (2 cm length) were used for the visualization of thrombus-device interaction during retrieval. The Phenox CRC (4 mm diameter) was assessed in 15 vessel occlusions. For every occlusion a maximum of 3 retrieval attempts were performed. Complete recanalization (TICI 3/TIMI 3) was achieved in 86.7% of vessel occlusions. In 66.7% (10/15), the first retrieval attempt was successful, and in 20% (3/15), the second attempt led to complete recanalization of the parent artery. In 2 cases (13.3%) thrombus retrieval was not successful (TICI 0/TIMI 0). In 1 case (6.7%) a minor embolic event occurred in a small side branch. No distal thromboembolic event was observed during the study. Thrombus-device interaction illustrated the entrapment of the thrombus by the microfilaments and the proximal cage of the device. No significant thrombus compression was observed. No vessel perforation, dissection, or fracture of the device occurred. In this small animal study, the Phenox CRC was a safe and effective device for mechanical thrombectomy. The unique design with a combination of microfilaments and proximal cage reduces thrombus compression with a consequently high recanalization and low complication rate.
