Innovative Bauweisen mit Sonderbetonen: Lösung bautechnischer Herausforderungen beim Umbau der Schleuse Rahe ermöglicht Schleusenbetrieb während der Baumaßnahme
Authors: Petersen Lasse , Lohaus Ludger , Schönebeck Dieter 
Published: October 2006

AbstractInnovation und der Mut zu technisch anspruchsvollen Erstanwendungen zahlt sich im Baustellenalltag immer häufiger aus. Technisch durchdachte Sondervorschläge mit innovativen Erstanwendungen sind dabei längst nicht mehr besonders exponierten Großprojekten vorbehalten. Vielmehr scheint sich mehr und mehr durchzusetzen, auch bei kleineren und mittleren Baumaßnahmen durch innovative Sondervorschläge technisch hochwertigere oder aber kostengünstigere Vorgehensweisen zu entwickeln und damit dem allgemeinen Preiskampf auszuweichen. Dabei liegt ein großes Potential in der Entwicklung projektspezifischer Sonderbetone, die deutlich effektivere Bauverfahren ermöglichen. Der vorliegende Bericht beschreibt den Umbau der Schleuse Rahe bei Aurich, bei der im Rahmen eines Sondervorschlages erstmals ein neuartiges Bauverfahren mit großformatigen, auf der Baustelle hergestellten Fertigteilen eingesetzt wurde. Die Fertigteile wurden im Rahmen einer Unterwasserverfüllung mit einem selbstnivellierenden und gleichzeitig erosionsstabilen Zementleim oder aber mit einem Selbstverdichtenden Unterwasserbeton vergossen.
Development, implementation and prospective evaluation of guidelines for transfer of severely injured children to specialist centres
Authors: Patterson M , Jones M , Lloyd D A 
Published: October 2006

Abstract

Background
Most injured children are appropriately treated at a district general hospital (DGH), but some require transfer to a specialist centre. The objectives of this study were to develop, implement and evaluate triage guidelines for the rapid recognition of injured children who require transfer.

Methods
This was a prospective, interventional cohort study of the 592 seriously injured children who presented to five regional DGHs during a 51-month period. A multispecialty steering group representing all participating DGHs developed and implemented the guidelines. Data were collected for 24 months before the guidelines were introduced, over the 3-month implementation period and for 24 months afterwards. Outcome measures were referral and management patterns before and after introduction of the guidelines.

Results
For level I (unstable) patients, after the implementation of guidelines there was a 29 per cent increase in the proportion of transfers to a specialist centre (from 40 (68 per cent) of 59 to 32 (97 per cent) of 33; P = 0·003), no admissions to a DGH intensive care unit and all 12 operations were performed at a specialist centre. Guideline users indicated that they were familiar with the guidelines.

Conclusion
The introduction of triage guidelines within an effective communication network was associated with changes in the management of severely injured children.
Do tests of malingering concur? Concordance among malingering measures
Authors: Farkas Melanie R. , Rosenfeld Barry , Robbins Reuben , van Gorp Wilfred 
Published: October 2006

AbstractMalingering test accuracy is increasingly a major issue in psychology and law. Integrating results across measures might offset limitations of a single test, but the practical benefits of using several tests depend on the extent to which they misclassify the same individuals. Data from 66 evaluatees were used to assess the degree of overlap and consistency of classification among several commonly used malingering instruments. Although correlative data indicated that measures were highly redundant even across symptom domains, classification accuracy analyses revealed that findings based on conjunctions of these scales may not overlap to the degree that the correlations might suggest.

Adults' ability to detect children's lying
Authors: Crossman Angela M. , Lewis Michael 
Published: October 2006

AbstractAdults are poor deception detectors when examining lies told by adults, on average. However, there are some adults who are better at detecting lies than others. Children learn to lie at a very young age, a behavior that is socialized by parents. Yet, less is known about the ability to detect children's lies, particularly with regard to individual differences in the ability to detect this deception. The current study explored adult raters' ability to discern honesty in children who lied or told the truth about committing a misdeed. Results showed that adults are no better at detecting children's lies than they are with adult lies. In particular, adults were very poor at identifying children's honest statements. However, individual differences did emerge, suggesting that the ability to detect lying in children might be facilitated by relevant experience working with children. Implications for legal and mental health contexts are discussed. Copyright © 2006 John Wiley & Sons, Ltd.

Published: October 2006

AbstractThe characterisation of a series of compounds obtained from Woollins' reagent (W.R.) offers a novel approach to organometallic coordination polymers. The syntheses were achieved by nucleophilic ring‐opening reactions of W.R. with metal salts and crystallisation using solvent‐diffusion techniques. One‐dimensional coordination polymers are formed as a result, and we demonstrate that the dimensionality of the polymers can be influenced by using hydrated metal salts or by the construction of heterometallic arrangements.
The Self‐Ordering Properties of Novel Phthalocyanines with Out‐of‐Plane Alkyl Substituents

Published: October 2006

AbstractTwo novel homologous series of phthalocyanines were prepared from 2,2‐dialkylindane and 2,2‐dialkyl‐1,3‐benzodioxole precursors. It was anticipated that attaching alkyl chains to five‐membered rings, fused to the peripheral sites of the phthalocyanine ring, would result in the adoption of an out‐of‐plane configuration and thereby discourage cofacial aggregation, to provide an analogy with picket‐fence porphyrins. This strategy proved partially successful. Some members of the series of phthalocyanines derived from 2,2‐dialkyl‐1,3‐benzodioxoles, in which the alkyl chains are linked to the phthalocyanine via a cyclic ketal, form spin‐coated thin films in which the phthalocyanine cores are perfectly isolated. This behaviour is associated with the formation of a disordered crystal that appears as a mesophase in the thermal profile of these materials. However, the phthalocyanines derived from 2,2‐dialkylindanes display a columnar mesophase over a wide temperature range, with some liquid crystalline derivatives at ambient temperature. A single‐crystal X‐ray diffraction structure of the octahexyl derivative of this series shows how the columnar assembly accommodates the out‐of‐plane alkyl chains by tilting the macrocyclic plane of the phthalocyanine components with respect to the axis of the column. This study helps to emphasise the importance of both the steric and electronic effects of substituents on the packing behaviour of phthalocyanines in the condensed phase, and especially the role of electron‐donating oxygen atoms directly attached to the ring.
Acoustical Studies of Some Schiff Bases in 1,4‐Dioxane and Dimethylformamide at 318.15 K
Authors: Baluja Shipra 
Published: October 2006

AbstractFrom experimental data of density, viscosity and ultrasonic velocity, the various acoustical properties, such as specific impedance (Z), isentropic compressibility (κs), Rao's molar sound function (Rm), the van der Waals constant (b), molar compressibility (W), intermolecular free length (Lf), relaxation strength (r), internal pressure (π), free volume (Vf), solvation number (Sn) etc., were calculated for three Schiff bases in 1,4‐dioxane and dimethylformamide (DMF) at 318.15 K. The results are interpreted in terms of molecular interactions occurring in the solutions.

Published: October 2006

AbstractStatic headspace GC‐MS method coupled with H/D exchange was firstly developed to determine and identify the volatile components in the fresh root and rhizome of Curcuma wenyujin. The TIC chromatograms of 3 batches of fresh roots harvested at different time showed significant difference in the volatile components:the constitution was the same but the content of them was different. More than 60 volatile components in fresh roots (Root of C. wenyujin) and rhizomes (Rhizome of C. wenyujin) of C. wenyujin were detected, of which 51 and 48 volatile components were identified respectively. The fresh roots and rhizomes of C. wenyujin were found to have the similar volatile components. The contents of these components were calibrated by the response of β‐elemene. In addition, the principal active component, β‐elemene, was further confirmed and relatively quantified by its standard. γ‐terpinene showed obvious allylic hydrogen/deuterium exchange using deuterium oxide which gave a new method to identify some compounds containing allylic hydrogen. At the same time, the active hydrogen compounds were also further confirmed. The results show that HS‐GC‐MS method is a fast, simple and efficient way for the analysis of volatile components from medical plants.

Published: October 2006

AbstractTwo new supramolecular complexes, [Cu(H2dhbd)(3‐pyOH)(H2O)]2·3‐pyOH·2H2O (1) and [Cu2(dhbd)(dpa)2‐ (H2O)]·6H2O (2) (H4dhbd=2,3‐dihydroxybutanedioic acid, 3‐pyOH=3‐hydroxypyridine, dpa=2,2′‐dipyridylamine), have been synthesized in aqueous solution and characterized by single‐crystal X‐ray diffraction, elemental analyses, UV‐Vis and IR spectra, and TGA analysis. X‐ray structural analysis revealed that, through four pairs of strong O···H–O hydrogen bonds, the cyclic dinuclear units in 1 together with four adjacent neighbors are connected into a 2D honeycomb network encapsulating free 3‐pyOH ligands. Unexpectedly, the water‐dimers are fixed in interlayers of 2D honeycomb network and act as hydrogen‐bond bridging to further extend these 2D networks into 3D hydrogen‐bonded framework. Complex 2 includes interesting 2D grids constructed from chiral dinuclear units through strong O···H–O and O···H–N hydrogen bonding, which are extended through other crystallization water molecules into three dimension with channels. Variable‐temperature magnetic susceptibility measurements for both complexes indicate the presence of weak antiferromagnetic exchange interactions between adjacent copper(II) ions.

Authors: Wang Zeng‐Lin , Zhang Mei‐Li , Liu Zong‐Huai , Yang Zu‐Pei 
Published: October 2006

AbstractA series of Ln(tmtaa)(Htmtaa)·CH2Cl2 (Ln=Sm, Tb, Er and Yb) complexes were prepared and characterized by infrared spectra, mass spectra and molecular electronic spectroscopy as well as DSC measurement. A sandwich structure containing all the eight nitrogen atoms of tmtaa and Htmtaa was proposed for these complexes. X‐ray photoelectron spectra (XPS) of these complexes revealed that four nitrogen atoms of both tmtaa and Htmtaa were chemically equivalent to each other, respectively. The acidic hydrogen of Htmtaa did not bind specifically to any nitrogen atom of Htmtaa, but was shared by all the four nitrogen atoms. The magnetic properties of these complexes were found to be in good agreement with their theoretical values.

AbstractThe interaction of Chinese herbal medicine component flavonoids (morin and rutin) with trivalent aluminium ion and the complex of aluminium ion and Bovine Serum Albumin in Hank′s artificial simulate body fluid was studied using UV‐Vis absorption spectra. The result showed that morin and rutin could conjugate with Al3+ in Hank′s artificial simulate body fluid. It was found that morin and rutin could competed with the complex of aluminium ion and Bovine Serum Albumin for aluminium ion. The mechanism of flavonoids and Bovine Serum Albumin compete aluminium ion was discussed, and the constant of rutin complex with aluminium ion was calculated.

AbstractIn this paper, a series of new optically active MeO‐BIPHEP‐type ligands, (S)‐6,6′‐dimethoxy‐2,2′‐bis(di‐ p‐alkoxyphenyl‐phosphine)‐1,1′‐biphenyl [(S)‐5b–(S)‐5e] were prepared and characterized. Starting from the commercially available triethyl phosphorite and m‐bromoanisole, an optically active (S)‐6,6′‐dimethoxybiphenyl‐ 2,2′‐diyl‐bis(phosphonic acid diester) was prepared by an improved way and converted to the corresponding dichlorides, which was used as a key intermediate to react with p‐alkoxybenzenemagnesium bromide or p‐alkoxyphenyl lithium to directly give the enantiomerically pure diphosphines 5.
Catalytic Trimerization of Ethylene with Highly Active Half‐sandwich Titanium Complexes Bearing Pendant p‐Fluorophenyl Groups
Authors: Wang Chen , Huang Ji‐Ling 
Published: October 2006

AbstractTwo new complexes [η5‐C5H4CMe2‐(p‐fluorophenyl)]TiCl3 (1) and [η5‐C5H4C(cyclo‐C5H10)‐(p‐fluoro‐phenyl)]TiCl3 (2) were synthesized and characterized. Their activities and selectivities for trimerization of ethylene were investigated. The introduction of fluorine atom greatly weakened the arene coordination, but this disadvantageous factor can be eliminated by introduction of a bulky substituent, such as cyclo‐C5H10, to the bridging carbon linked to the Cp ring. The combinative effect of the fluorine substitute and the bridging unit can make complex 2 as a highly active and selective catalyst for ethylene trimerization. Its productivity and selectivity for 1‐hexene can reach 1024.0 kg·mol−1·h−1 and 99.3% respectively.
Study on the Anion Recognition Properties of Synthesized Receptors (III): Convenient Synthesis and Anion Recognition Property of Bisthiosemicarbazone Derivative
Authors: Zhang You‐Ming , Xu Wei‐Xia , Yao Hong , Wei Tai‐Bao 
Published: October 2006

AbstractA new series of bisthiosemicarbazone derivative receptors (1, 2 and 3) have been synthesized by simple steps in good yields. Their anion recognition properties were studied by UV‐Vis and 1H NMR spectroscopy. The result showed that the receptors 1, 2 and 3 all had a better selectivity to F−, CH3COO− and H2PO4−, but no evident binding with Cl−, Br−, I−, NO3− and HSO4−. Upon addition of the three anions to the receptors in DMSO, the solution acquired a color change from colorless to dark yellow that can be observed by the naked‐eyes, thus the receptors can act as fluoride ion sensors even in the presence of other halide ions. The data showed that it was regular that the three receptors had different binding ability with the three anions. For the same anion, the association constants followed the trend: receptor 1>3>2. The UV‐Vis data indicates that a 1:1 stoichiometry complex is formed through hydrogen bonding interactions between compound 1, 2 or 3 and anions.

Published: October 2006

AbstractAladan {β‐[6′‐(N,N‐dimethyl)amino‐2′‐naphthoyl]alanine} and aladan‐containing cyclodecapeptide [Ald6]‐ loloatin C were synthesized. The properties of their fluorescent behaviours both in aqueous buffer and micelles created by sodium dodecylsulfate (SDS) and dodecylphosphorylcholine (DPC) were further investigated. It was found that in either of micelle systems, [Ald6]loloatin C possesses red‐shift emission maximum wavelength and higher quantum yield. This property could be useful in the research of peptide‐cell membrane interaction.

Published: October 2006

AbstractThree metal ion bridged self‐assembled (SA) films of cis‐di(thiocyanato)‐bis(2,2′‐bipyridyl‐4,4′‐dicarboxylate) ruthenium were fabricated and characterized by contact angle, UV spectra, cyclic voltammetry and XPS. Their photoinduced electron transfer properties (PETP) were examined. Among the titled systems, the highest steady anodic photocurrent of 1773–1843 nA/cm2 and the highest quantum yield of 3.2% were achieved. The effects of incident light intensity, bias voltage, and electron donor were also studied. The possible mechanism of electron transfer was proposed. The results reveal that different metal ion in SA films could affect significantly the photoinduced electron transfer property. Our experimental results clearly show that bridging metal ions can play both functional and structural roles in these self‐assembled systems. This method of forming functional films can provide a new approach to regulate the property of similar systems.

Effects of human contact and vagal regulation on pain reactivity and visual attention in newborns
Authors: Arditi Hadar , Feldman Ruth , Eidelman Arthur I. 
Published: October 2006

AbstractIn two experiments we examined the effects of human contact and vagal regulation on newborns' pain reactivity and visual attention. Baseline cardiac vagal tone was measured during quiet sleep and during the experiment, and vagal withdrawal was indexed as change in vagal tone from baseline to pain (study 1) or attention (study 2). In study 1, 62 healthy newborns were videotaped during a heel‐prick procedure and pain reactivity was assessed from micro‐level coding of facial expressions, cry behavior, and body movements. Infants were randomly assigned to a contact condition, held by a female assistant, or a no contact condition, on an infant‐seat in a similar angle. In study 2, 62 additional healthy newborns, randomly assigned to contact and noncontact conditions, were presented with 2 visual stimuli for a 60 s familiarization period, which were then paired with a novel stimulus. Visual interest, alertness, and novelty preference were coded. Human contact had no effect on the newborns' pain response. Visual attention increased with human contact and newborns in the contact condition looked at the stimuli more frequently, with higher alertness, for longer durations, and had a higher novelty preference. Autonomic reactivity—as indexed by vagal withdrawal‐differentiated newborns with intense and mild pain response. Discussion focused on proximity to conspecifics as a contributor to emerging regulatory and adaptive functioning in the human infant. © 2006 Wiley Periodicals, Inc. Dev Psychobiol 48: 561–573, 2006.
Head‐cocking as a form of exploration in the common marmoset and its development
Authors: Kaplan Gisela , Rogers Lesley J. 
Published: October 2006

AbstractHead‐cocking of 15 infant marmosets (Callithrix jacchus) was scored from Day 1 to 60 of postnatal life, the growth period with overproduction of interneuronal synapses. Head‐cocking was scored during four 30 min intervals daily, including angle of head‐cocking and objects being fixated. Mean age of onset of head‐cocking was Day 13 (±1.3) and frequency increased to a fixed rate by Day 24–29, at the time of maturation of the foveal representation in layer 6 of the visual cortex, thus lending further support to the importance of head‐cocking to visual processing. The most common distance of objects fixated during head‐cocking was up to .5 m. Angle of head‐cocking increased with age, and some asymmetry of direction was noted. Fewer head‐cocking events occurred in the morning than in the afternoon. We also scored anogenital licking of offspring. Head‐cocking occurred at higher levels in marmosets receiving more anogenital licking. As this was associated positively with increased exploration, head‐cocking may be regarded as an exploratory behavior. © 2006 Wiley Periodicals, Inc. Dev Psychobiol 48: 551–560, 2006.
