Bone fractures as indicators of intentional violence in the eastern adriatic from the antique to the late medieval period (2nd–16th century AD)
Authors: Šlaus Mario , Novak Mario , Bedić Željka , Strinović Davor
Published: May 2012

To test the historically documented hypothesis of a general increase in deliberate violence in the eastern Adriatic from the antique (AN; 2nd–6th c.) through the early medieval (EM; 7th–11th c.) to the late‐medieval period (LM; 12th–16th c.), an analysis of the frequency and patterning of bone trauma was conducted in three skeletal series from these time periods. A total of 1,125 adult skeletons—346 from the AN, 313 from the EM, and 466 from the LM series—were analyzed. To differentiate between intentional violence and accidental injuries, data for trauma frequencies were collected for the complete skeleton, individual long bones, and the craniofacial region as well as by type of injury (perimortem vs. antemortem). The results of our analyses show a significant temporal increase in total fracture frequencies when calculated by skeleton as well as of individuals exhibiting one skeletal indicator of deliberate violence (sharp force lesions, craniofacial injuries, “parry” fractures, or perimortem trauma). No significant temporal increases were, however, noted in the frequencies of craniofacial trauma, “parry” fractures, perimortem injuries, or of individuals exhibiting multiple skeletal indicators of intentional violence. Cumulatively, these data suggest that the temporal increase in total fracture frequencies recorded in the eastern Adriatic was caused by a combination of factors that included not only an increase of intentional violence but also a significant change in lifestyle that accompanied the transition from a relatively affluent AN urban lifestyle to a more primitive rural medieval way of life.

Properties of 2,2‐Bis[p‐(2′‐hydroxy‐3′‐methacryloxy propoxy)phenyl]propane/Isobornyl (Meth)acrylate copolymers
Authors: He Jingwei , Liu Fang , Luo Yuanfang , Jia Demin
Published: May 2012

Isobornyl acrylate (IBOA) and isobornyl methacrylate (IBOMA) were used to replace triethylene glycol dimethacrylate (TEGDMA) as reactive diluents in dental restorative materials. Photopolymerization behaviors of mixtures of IBO(M)A and 2,2‐bis[p‐(2′‐hydroxy‐3′‐methacryloxy propoxy)phenyl]propane (Bis‐GMA) were investigated by Fourier transform infrared spectroscopy. The degree of conversion, volume shrinkage, contact angle, water sorption, water solubility, flexural strength, and modulus values of the Bis‐GMA/IBO(M)A formulations were measured and compared with those of a Bis‐GMA/TEGDMA formulation. The results illustrate that the degree of conversion, volume shrinkage, contact angle, water sorption, flexural strength, and modulus values of the Bis‐GMA/IBO(M)A systems were all lower than those of the Bis‐GMA/TEGDMA system; the water solubility values of the Bis‐GMA/IBO(M)A systems were higher than that of the Bis‐GMA/TEGDMA system. © 2012 Wiley Periodicals, Inc.

Physical wrapping of reduced graphene oxide sheets by polyethylene wax and its modification on the mechanical properties of polyethylene
Authors: Cao Zhenhu , Song Pingan , Fang Zhengping , Xu Yuanyuan , Zhang Yan , Guo Zhenghong
Published: May 2012

A facile method to encapsulate the reduced graphene oxide (RGO) sheets physically with polyethylene (PE) wax was developed. The graphene oxide sheets were first wrapped with polyethylene wax, and reduced by hydrazine hydrate. The structure of the wrapped RGO was confirmed by means of Fourier transform infrared spectroscopy, X‐ray diffraction (XRD), and Raman spectroscopy. The PE wax‐wrapped RGO sheets were melt blended with PE to prepare PE/RGO nanocomposites. Transmission electron microscopy and XRD studies showed that this method could provide uniform dispersion of RGO sheets in the PE matrix. Scanning electron microscopy and Raman spectroscopy indicated that there was a strong interfacial interaction between the PE wax‐wrapped RGO sheets and PE matrix. Addition of 1 wt % RGO sheets in PE matrix led to a 48% increment in the yield stress and 118% increment in the Young's modulus, respectively. However, the elongation at break decreased with increasing RGO sheets loading content. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
The effect of melt spinning process parameters on the spinnability of polyetheretherketone
Authors: Mylläri Ville , Skrifvars Mikael , Syrjälä Seppo , Järvelä Pentti
Published: May 2012

This study has been carried out to investigate the processing parameters affecting polyetheretherketone's (PEEK) spinnability in a melt spinning process. PEEK has excellent mechanical and thermal properties and fibers made from it could be used in extreme environments. Different PEEK grades were characterized thermally and rheologically to see which one is the most suitable for fiber spinning. The spinning tests made with the most suitable grade (Victrex 151G) show that increased processing temperature, increased capillary diameter or shorter spinning path length improves spinnability. The best fibers made in optimal processing conditions (400°C temperature, 30/1 mm capillary, and 5 cm spinning path) were 18 μm in average diameter. Because of the limitations of the system used, variations in fiber thickness were noticeable and worsened the spinning stability. Scanning electron microscope photos confirmed these variations, and they were also visible in an optical microscope. The selected low‐viscosity PEEK grade provided good spinnability but gave filaments with only mediocre mechanical properties, the tensile strength being around 280 MPa. © 2012 Wiley Periodicals, Inc.

High survivorship of an annually decreasing aggregation of hawksbill turtles, Eretmochelys imbricata, found foraging in the northern Great Barrier Reef
Authors: Bell Ian , Schwarzkopf Lin , Manicom Carryn
Published: May 2012

An 8‐year study of the foraging abundance of an Eretmochelys imbricata aggregation, found on 13 reefs (Howick Group) within the northern section of the Great Barrier Reef Marine Park was undertaken.

A Cormack–Jolly–Seber method within program MARK was used to: (1) compare survival and recapture probabilities among age and sex classes of turtles; and (2) estimate survival and recapture rates for male and female adults and sub‐adults from 665 capture–mark–recapture profiles of E. imbricata.

Mean annual population density estimates were consistently greater for adult female E. imbricata (n = 333.7; SD = 135.6; R = 221–581) than for adult males (n = 32.4; SD = 33.4; R = 8–98), with both adult males and females displaying high survivorship rates (71.1%; 92.2%, respectively). This was also apparent in immature age‐classes, with male and female turtles showing similarly high survivorship likelihoods (78.0%; 93.0%, respectively).

Both sexes exhibited a similar overall trend with a peak population density being displayed in the first two years of the study, followed by a general decline in the female stock and stable male population.

These are the only reliable long‐term abundance time‐series data for a population that includes all age‐classes of E. imbricata in the western Pacific and provide good baseline data for the detection of possible climate change induced trends.

Published: May 2012

The synthesis and the solid state magnetic properties of (nitronyl nitroxide)‐substituted trioxytriphenylamine radical cation tetrachlorogallate, NNTOT+·GaCl4−, are reported. In the temperature region between 300 and 3 K, the magnetic behavior is characterized by the strong intramolecular ferromagnetic interaction (J/kB=+400 K) between the radical (NN) and the radical cation (TOT+) and the weak intermolecular antiferromagnetic interaction (J/kB=−1.9 K) between NNTOT+ ions. Below 3 K, a 3D‐type long‐range magnetic ordering into a weak ferromagnet was observed (TN=2.65 K). The magnetic entropy (Smag=8.97 J K−1 mol−1) obtained by the heat capacity measurement is in good agreement with the theoretical value of R ln3=9.13 J K−1 mol−1 based on the S=1 state.
Synthesis of Continuous Mesoporous Alumina Films with Large‐Sized Cage‐Type Mesopores by Using Diblock Copolymers
Authors: Jiang Xiangfen , Suzuki Norihiro , Bastakoti Bishnu Prasad , Wu Kevin C.‐W. , Yamauchi Yusuke
Published: May 2012

Mesoporous alumina films with large‐sized cage‐type mesopores were prepared by using commercially available diblock copolymer (PS‐b‐PEO) and economic inorganic salt (AlCl3) as aluminum source. The obtained mesopore sizes drastically expand from 35 nm to 80 nm when the amount of ethanol in the precursor solutions were controlled. More interestingly, under an optimized amount of ethanol as co‐solvent, there was no significant change of micelle morphology on the substrate, even though the relative amount of PS‐b‐PEO to alumina source was dramatically varied. When the amount of alumina precursor was decreased, the pore walls gradually became thinner, thereby improving pore connectivity. The ordered mesoporous alumina films obtained in this study exhibit high thermal stability up to 1000 °C, and their frameworks are successfully crystallized to γ‐alumina phase. This technique could also be applicable for creating other metal oxide thin films with large mesopores.

Published: May 2012

Wireless local area networks are an increasing alternative to wired data networks in workplaces, homes, and public areas. Concerns about possible health effects of this type of signal, especially when exposure occurs early in life, have been raised. We examined the effects of prenatal (in utero) exposure to wireless fidelity (WiFi) signal‐associated electromagnetic fields (2450 MHz center‐frequency band) on T cell development and function. Pregnant mice were exposed whole body to a specific absorption rate of 4 W/kg, 2 h per day, starting 5 days after mating and ending 1 day before the expected delivery. Sham‐exposed and cage control groups were used as controls. No effects on cell count, phenotype, and proliferation of thymocytes were observed. Also, spleen cell count, CD4/CD8 cell frequencies, T cell proliferation, and cytokine production were not affected by the exposure. These findings were consistently observed in the male and female offspring at early (5 weeks of age) and late (26 weeks of age) time points. Nevertheless, the expected differences associated with aging and/or gender were confirmed. In conclusion, our results do not support the hypothesis that the exposure to WiFi signals during prenatal life results in detrimental effects on the immune T cell compartment.

TREATMENT OF VOCAL STEREOTYPY IN AN ANALOGUE AND CLASSROOM SETTING
Authors: Shillingsburg M. Alice , Lomas Joanna E. , Bradley Danielle
Published: May 2012

Vocal stereotypy is commonly seen in individuals diagnosed with autism. Vocal stereotypy maintained by automatic reinforcement may prove challenging to treat because of difficulty controlling access to the reinforcer for the behavior. Although previous research has shown reductions in vocal stereotypy using noncontingent reinforcement with and without a response cost component, these types of interventions may not be feasible in the natural environment. The present study presents a treatment package, conducive to the natural environment, consisting of a token economy with a response cost to reduce vocal stereotypy in a male adolescent with autism. Vocal stereotypy was reduced to near zero levels in both an analogue and classroom setting. Copyright © 2012 John Wiley & Sons, Ltd.
Serial assembly of Thermus megaplasmid DNA in the genome of Bacillus subtilis 168: A BAC‐based domino method applied to DNA with a high GC content
Authors: Ohtani Naoto , Hasegawa Miki , Sato Mitsuru , Tomita Masaru , Kaneko Shinya , Itaya Mitsuhiro
Published: May 2012

Bacillus subtilis is the only bacterium‐based host able to clone giant DNA above 1000 kbp. DNA previously handled by this host was limited to that with GC content similar to or lower than that of the B. subtilis genome. To expand the target DNA range to higher GC content, we tried to clone a pTT27 megaplasmid (257 kbp, 69% of G+C) from Thermus thermophilus. To facilitate the reconstruction process, we subcloned pTT27 in a bacterial artificial chromosome (BAC) vector of Escherichia coli. Owing to the ability of BAC to carry around 100 kbp DNA, only 4 clones were needed to cover the pTT27 and conduct step‐by‐step assembly in the B. subtilis genome. The full length of 257 kbp was reconstructed through 3 intermediary lengths (108, 153, and 226 kbp), despite an unexpected difficulty in the maintenance of DNA >200 kbp. Retrieval of these four pTT27 segments from the B. subtilis genome by genetic transfer to a plasmid pLS20 was attempted. A stable plasmid clone was obtained only for the 108 and 153 kbp intermediates. The B. subtilis genome was demonstrated to accommodate large DNA with a high GC content, but may be restricted to less than 200 kbp by unidentified mechanisms.
Process Intensification by Membrane Reactors: High‐Temperature Water Gas Shift Reaction as Single Stage for Syngas Upgrading
Authors: Brunetti A. , Caravella A. , Drioli E. , Barbieri G.
Published: May 2012

Pd‐based membrane reactors (MRs) selectively removing hydrogen shift the equilibrium conversion of this new reactor type to values higher than those imposed by thermodynamics to traditional reactors. Thus, the equilibrium conversion of CO is significantly increased and can be very strongly depending on the hydrogen extracted also at a higher temperature. This property of the MRs offers important benefits also in terms of process intensification. In the typical high‐temperature range for this reaction, i.e., 300–450 °C, the performance of an MR turned out to be so effective that the two reactors of a traditional process can be replaced by one MR of lower volume, too. The conversion of the MR is higher than the one of the whole traditional process which includes a heat exchanger in addition to two reactors. Consequently, less and smaller unit operations are required when an MR operates the water gas shift reaction pursuing the process intensification philosophy.
A Microplasma Reactor for Chemical Process Intensification
Authors: Lindner P. J. , Besser R. S.
Published: May 2012

A novel approach to chemical process intensification based on microplasma reactor systems is presented. Microplasmas (plasmas generated in sub‐mm volumes) possess a favorable reaction environment because of high densities of reactive ions, radicals, and electrons. Moreover, operation under atmospheric pressure and near‐room temperature makes them convenient for implementation. Experiments utilized a microfabricated microplasma reactor to intensify the reforming of methanol into a hydrogen‐rich product stream useful for energy applications such as combustion or fuel cells. A reaction model elaborates the key mechanisms and demonstrates that reaction rates in the microplasma environment surpass those of conventional plasma reactors. The outcome is that microplasma chemical processing is a viable approach for hydrocarbon reforming and merits consideration for other chemical reaction applications.
Photoinduced Energy and Electron Transfer in Phenylethynyl‐Bridged Zinc Porphyrin–Oligothienylenevinylene–C60 Ensembles
Authors: Urbani Maxence , Ohkubo Kei , Islam D. M. Shafiqul , Fukuzumi Shunichi , Langa Fernando
Published: May 2012

Donor–bridge–acceptor triad (Por‐2TV‐C60) and tetrad molecules ((Por)2‐2TV‐C60), which incorporated C60 and one or two porphyrin molecules that were covalently linked through a phenylethynyl‐oligothienylenevinylene bridge, were synthesized. Their photodynamics were investigated by fluorescence measurements, and by femto‐ and nanosecond laser flash photolysis. First, photoinduced energy transfer from the porphyrin to the C60 moiety occurred rather than electron transfer, followed by electron transfer from the oligothienylenevinylene to the singlet excited state of the C60 moiety to produce the radical cation of oligothienylenevinylene and the radical anion of C60. Then, back‐electron transfer occurred to afford the triplet excited state of the oligothienylenevinylene moiety rather than the ground state. Thus, the porphyrin units in (Por)‐2TV‐C60 and (Por)2‐2TV‐C60 acted as efficient photosensitizers for the charge separation between oligothienylenevinylene and C60.
Surface‐Plasmon‐Enhanced Band Emission of ZnO Nanoflowers Decorated with Au Nanoparticles
Authors: Kochuveedu Saji Thomas , Oh Ji Hye , Do Young Rag , Kim Dong Ha
Published: May 2012

A simple strategy was used to enhance band emission through the transfer of defect emission from ZnO to Au by using the energy match between the defect emission of ZnO and the surface plasmon absorbance of Au NPs through decorating the surface of ZnO nanoflowers with Au nanoparticles (Au NPs). The ZnO nanostructure, which was comprised of six nanorods that were attached on one side in a flower‐like fashion, was synthesized by using a hydrothermal method. The temperature‐dependent morphology and detailed growth mechanism were studied. The influence of the density of the Au NPs that were deposited onto the surface of ZnO on photoluminescence was investigated to optimize the configuration of the ZnO/Au system in terms of the maximum band emission. The sequential transfer of defect energy from ZnO to Au and electron transfer from excited Au to ZnO was proposed as a possible mechanism for the enhanced band emission.

Long‐Term Stability, Regeneration and Recycling of Imidazolium‐based Ionic Liquids
Authors: Keil Philipp , Kick Matthias , König Axel
Published: May 2012

Ionic liquids (ILs) are discussed in many current research papers extensively in terms of their potential use in the chemical industry, as process aids and novel materials. The long‐term stability of the IL is for industrial applications as important as to know which species arise during the degradation due to thermal, mechanical, chemical or electrochemical stress. The investigation of the long‐term stability of two selected ILs over several months under process‐like conditions is presented with a subsequent analysis by LC‐MS to identify the resulting decomposition products. Knowledge about the occurring species and their analytical quantification are basis for the selection of appropriate processes for the separation of the decomposition products and the development of recycling processes for ILs. Particularly melt crystallization processes are suitable for separating structurally similar decomposition products that typically occur in the IL degradation.
Batch and fixed‐bed column adsorption of Cu(II), Pb(II) and Cd(II) from aqueous solution onto functionalised SBA‐15 mesoporous silica
Authors: Shahbazi Afsaneh , Younesi Habibollah , Badiei Alireza
Published: May 2012

Functionalised SBA‐15 mesoporous silica with polyamidoamine groups (PAMAM‐SBA‐15) was successfully prepared with the structure characterised by X‐ray diffraction, nitrogen adsorption–desorption, Fourier transform infrared spectra and thermogravimetric analysis. PAMAM‐SBA‐15 was applied as adsorbent for Cu(II), Pb(II) and Cd(II) ions removal from aqueous solution. The effects of the solution pH, adsorbent dosage and metal ion concentration were studied under the batch mode. The Langmuir model was fitted favourably to the experimental data. The maximum sorptive capacities were determined to be 1.74 mmol g−1 for Cu(II), 1.16 mmol g−1 for Pb(II) and 0.97 mmol g−1 for Cd(II). The overall sorption process was fast and its kinetics was fitted well to a pseudo‐first‐order kinetic model. The mean free energy of sorption, calculated from the Dubinin–Radushkevich isotherm, indicated that the sorption of lead and copper, with E > 16 kJ mol−1, followed the sorption mechanism by particle diffusion. The adsorbent could be regenerated three times without significant varying its sorption capacity. A series of column tests were performed to determine the breakthrough curves with varying bed heights and flow rates. The breakthrough data gave a good fit to the Thomas model. Maximum sorption capacity of 1.6, 1.3 and 1.0 mmol g−1 were found for Cu(II), Pb(II) and Cd(II), respectively, at flow rate of 0.4 mL min−1 and bed height of 8 cm, which corresponds to 83%, 75% and 73% of metallic ion removal, respectively, which very close to the value determined in the batch process. Bed depth service time model could describe the breakthrough data from the column experiments properly. © 2012 Canadian Society for Chemical Engineering
