Protein influences on guayule and Hevea natural rubber sol and gel
Authors: McMahan Colleen , Kostyal David , Lhamo Dhondup , Cornish Katrina 
Published: February 2015

ABSTRACTGuayule (Parthenium argentatum) is under cultivation in the southwestern United States as an alternative source of natural rubber free from proteins that cause Type I latex allergies. However, since guayule lacks the protein‐polymer interactions present in Hevea latex, its physical and chemical properties may differ. The solvent‐soluble (Sol) and insoluble (Gel) fractions from guayule and Hevea natural rubbers were isolated through a solubilization/centrifugation deproteinization process. Protein could be reduced or removed by centrifugation, or concentrated in the gel fraction for both Hevea and guayule rubber. Separation of the sol fraction of Hevea rubber reduced the overall protein level, in some cases to below detection limits, without impacting rubber thermo‐oxidative stability. Notably, no detectable cross reactions took place between guayule protein antibodies and Hevea‐based materials, nor vice‐versa. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42051.
Iron(II) Disulfides as Precursors of Highly Selective Catalysts for Hydrodeoxygenation of Dibenzyl Ether into Toluene
Authors: Ji Na , Wang Xingyu , Weidenthaler Claudia , Spliethoff Bernd , Rinaldi Roberto 
Published: February 2015

AbstractIn this report, we show that nanocrystalline pyrite and marcasite (FeS2), supported on SBA‐15, aerosil SiO2, activated carbon or Al2O3, are precursors of highly active catalysts for the hydrodeoxygenation of dibenzyl ether into toluene. High yields of toluene (up to 100 %) were achieved in experiments performed at 250 °C under initial H2 pressure of 100 bar for 2 h. In the recycling experiments, results from XRD and XPS analyses indicate that a fresh surface, formed upon the chemical transformation of FeS2 into Fe(1−x)S, is responsible for the high activity and high selectivity achieved in the conversion of dibenzyl ether into toluene.
Solvent Influence on Cellulose 1,4‐β‐Glycosidic Bond Cleavage: A Molecular Dynamics and Metadynamics Study
Authors: Loerbroks Claudia , Boulanger Eliot , Thiel Walter 
Published: February 2015

AbstractWe explore the influence of two solvents, namely water and the ionic liquid 1‐ethyl‐3‐methylimidazolium acetate (EmimAc), on the conformations of two cellulose models (cellobiose and a chain of 40 glucose units) and the solvent impact on glycosidic bond cleavage by acid hydrolysis by using molecular dynamics and metadynamics simulations. We investigate the rotation around the glycosidic bond and ring puckering, as well as the anomeric effect and hydrogen bonds, in order to gauge the effect on the hydrolysis mechanism. We find that EmimAc eases hydrolysis through stronger solvent–cellulose interactions, which break structural and electronic barriers to hydrolysis. Our results indicate that hydrolysis in cellulose chains should start from the ends and not in the centre of the chain, which is less accessible to solvent.
Classification of SIM infill panels / Klassifikation von SIM‐Ausfachungswänden
Authors: Totoev Yuri 
Published: February 2015

AbstractSIM is an innovative building system for mortar‐less walls. It utilises a special method of interlocking SIM bricks that allows relative sliding of brick courses in‐plane of a wall and prevents out‐of‐plane relative movement of bricks. One of its structural applications is in multistorey frame buildings as earthquake resistant masonry infill panels. It improves energy dissipation of frame structures during earthquakes. The energy dissipation occurs through friction between bricks as they engage in relative sliding by the frame vibrating during earthquake. This paper explains the novelty of SIM and offers classification of SIM panels based on the gap width between the frame and the top of the panel.
Contribution of thermal resistance and thermal mass to the energy demand of walling systems / Beitrag des Wärmedurchlasswiderstandes und der thermischen Masse zum Energiebedarf von Wandsystemen
Authors: Alterman Dariusz , Page Adrian , Moghtaderi Behdad , Zhang Congcong 
Published: February 2015

AbstractThis paper describes an experimental investigation of the thermal performance of four common walling systems for Australian housing having a range of thermal resistance (R‐values) and varying degrees of external and internal thermal mass (i. e. inherent property of masonry constructions). The comparison is based on the energy demand under controlled conditions to maintain internal thermal comfort. The R‐values of each wall were first determined using a Guarded Hot Box Apparatus. The walls were then incorporated into four housing test modules built on the University of Newcastle campus and the detailed thermal performance of each system was observed under a range of seasonal conditions. The interior of each module was controlled within a comfort range by a heating/cooling system with the energy consumption being measured. Comparison of the energy requirements clearly show that internal comfort levels and energy demands are influenced by both the thermal resistance of the walls as well as the extent and location of the thermal mass, with neither being the sole predictor. The best thermal performance is therefore obtained by an appropriate combination of thermal mass and resistance, rather than focussing on the wall thermal resistance (R‐value) alone.
Volatile profile of Conciato Romano cheese, a traditional Italian cheese, during ripening
Authors: Caporaso Nicola , Armento Valentina , Sacchi Raffaele 
Published: February 2015

The aim of this paper was to characterize the complete volatile profile of Conciato Romano cheese, a traditional Italian product aged in a mixture of olive oil, wine, and spices, and its modification during ripening, by using SPME sampling and GC/MS analysis of volatiles and considering the rind and body parts separately. Seventy‐six volatile compounds were identified, belonging to chemical classes of acids (8), aldehydes (3), alcohols (14), esters (36), ketones (9), hydrocarbons (1), and terpenes (5). Acids and esters represented the most important chemical classes and are originated from lipolysis and hydrolysis of triglycerides. Aging caused dramatic changes in volatile compounds, particularly on the cheese rind, where the amount of esters, acids, alcohols, and ketones was found particularly abundant at 8 months of aging. Interesting differences were found in volatile headspace composition depending on the external or inner parts. The higher complexity in volatile profile of aged cheese was attributed both to the aging process and tanning mixture. Sensory analysis resulted in higher perception of “sweet” and “stickiness” and significantly lower olfactory persistence in fresh product, while higher values for “salty,” “spicy,” and “persistent” were found in aged ones.Practical applications: The results of our research can be useful to deepen knowledge of cheese volatile compounds and for a better understanding of the interactions between cheese aging and the use of a particular tanning mixture (olive oil, red wine, and spices), used in the Conciato Romano cheese. It can be used for a chemical characterization of the peculiarity found from sensory assessment of this cheese, as well as for control organisms, if further research would confirm the presence of volatile compounds as molecular markers. Finally, industry can take advantage of our research for possible future certifications of Conciato Romano as a Protected Designation of Origin.Conciato Romano, a typical and traditional Italian cheese, was studied to report its complete volatile profile by using the SPME‐GC‐MS technique. The volatile compounds were studied both in fresh and in 6‐ and 8 months‐aged cheese, by separately analyzing the rind and body of the product.
First Enantioselective Synthesis of Marine Diterpene Ambliol‐A
Authors: Serra Stefano , Lissoni Veronica 
Published: February 2015

AbstractThe first enantioselective synthesis of furanditerpene ambliol‐A, which is a major metabolite of marine spongeDysidea amblia, has been accomplished by starting from racemic α‐ionone. The key steps of the synthesis include lipase‐mediated resolution of 4‐hydroxy‐γ‐ionone, its stereoselective transformation intotrans‐α‐epoxy‐dihydroionone, C2homologation totrans‐α‐epoxy‐monocyclofarnesyl acetate and Li2CuCl4‐catalysed sp3–sp3cross‐coupling reaction of the latter ester with (furan‐3‐ylmethyl)magnesium chloride. This work confirms the chemical structure previously assigned to ambliol‐A and proves that the natural levorotatory isomer does not possess (1S,2S) absolute configuration, as previously indicated, but is the opposite enantiomer, (1R,2R)‐2‐[(E)‐6‐(furan‐3‐yl)‐3‐methylhex‐3‐enyl]‐1,3,3‐trimethylcyclohexanol.

Biomimetic Assembly of Leucoridine A
Authors: Benayad Sarah , Beniddir Mehdi A. , Evanno Laurent , Poupon Erwan 
Published: February 2015

AbstractThe three‐step biomimetic assembly of leucoridine A, a pseudosymmetric bisindole of Leuconotis griffithi (Apocynaceae) is described. The semisynthetic route provides suitable conditions toward the central 3‐spiro‐1,2,3,4‐tetrahydropiperidine ring connecting the two subunits of the highly congested structure. The biomimetic assembly by a Diels–Alder or alternatively an imino‐Rauhut–Currier reaction affords the natural (S)‐diastereomer of leucoridine A as the sole product. The sequence, repeated in a one‐pot cascade, supports a non‐enzymatic pathway for the assembly of this bisindole and the known related alkaloids.
Swivel‐Cruciform Stilbenes Based on Bithiophene

Published: February 2015

AbstractBithiophene‐based cruciforms with different stilbenoid arms at the 3,3′‐ and 5,5′‐positions have been synthesized by various combinations of Suzuki and Horner–Wadsworth–Emmons (HWE) reactions. According to DFT calculations, the steric hindrance between the arms at the 3,3′‐positions produces a twist angle of 57.6° between the two thiophene rings that form the 2,2′‐bithiophene unit, an arrangement that leads to a swivel‐cruciform structure. The UV/Vis spectra contained strong absorption bands at wavelengths consistent with a twisted molecule with little interaction between the arms. The ability of these compounds to form highly stable radical cations was demonstrated by cyclic voltammetry and this, together with their good solubility in organic solvents, indicates that these materials have potential for the development of solution‐processed electronic devices.
Computation of bridge seismic fragility by large‐scale simulation for probabilistic resilience analysis
Authors: Karamlou Aman , Bocchini Paolo 
Published: February 2015

SummarySeismic resilience of structures and infrastructure systems is a fast developing concept in the field of disaster management, promoting communities that are resistant and quickly recoverable in case of an extreme event. In this contest, probabilistic seismic demand and fragility analyses are two key elements of the seismic resilience assessment in the majority of the proposed methodologies. Several techniques are available to calculate fragility curves for different types of structures. In particular, to assess the seismic performance of the regional transportation infrastructure, methods for the fragility curve estimation for entire classes of bridges are required. These methods usually rely on a set of assumptions, partially because of the limited information. Other assumptions were introduced at the time when computational resources were inadequate for a purely numerical approach and closed‐form solutions were a convenient alternative. For instance, some of these popular assumptions are aimed at simplifying the model of the engineering demand. In this paper, a simulation‐based methodology is proposed, to take advantage of the computational resources widely available today and avoid such assumptions on the demand. The resulting increase in accuracy is estimated on a typical class of bridges (multi‐span simply supported). Most importantly, the quantitative impact of the assumptions is assessed in the context of a life‐cycle loss estimation analysis and resilience analysis. The results show that some assumptions preserve an acceptable level of accuracy, but others introduce a considerable error in the fragility curves and, in turn, in the expected resilience and life‐cycle losses of the structure.

Energy harvesting for assistive and mobile applications
Authors: Bhatnagar Vikrant , Owende Philip 
Published: February 2015

AbstractTechnology advances have enabled modification of the size and shape of the electronic components to the microscale, with commensurate scaling down of their power requirements to milliwatts and microwatt range. Consequently, many complex electronic systems and devices such as wearable medical and autonomous devices consume power in the range less than 200 μW, and wireless sensor networks in the range μW to 100 mW are operated on battery power. Due to the salient limitations of battery power, such as longevity of charge and where applicable, the requirement for periodic recharging, possibilities for utilization of autonomous energy sources is critical for operation of such devices. Ambient energy sources, such as vibrations (1 μW to 20 mW), motion (wide range in power outputs), temperature gradient (0.5–10 mW), radiofrequency waves (>180 μW/cm2), light (100 μW/cm2 to 100 mW/cm2), acoustics (0.003–0.11 μW/cm2), and many other, have the potential to directly power the electronic device. Ambient energy harvesting, when used separately or in conjunction with batteries, will enhance the longevity of equipment operations requiring portable or autonomous power supply. This paper reviews the state of the art in energy‐harvesting techniques, power conversion, and characterization of mini‐ and microscale self‐sustaining power generation systems in the range 600 μW to 5 W, specifically focusing on low‐power system applications, for personal assistive and mobile technology devices.

AbstractThe prognosis of chronic lymphocytic leukemia (CLL) patients displaying trisomy 12 (+12) remains unclear. In this study, we analyzed the influence of the proportion of cells with +12, and other clinical and biologic factors, in time to first therapy (TTFT) and overall survival (OS), in 289 patients diagnosed with CLL carrying +12. Median OS was 129 months. One hundred seventy‐four patients (60.2%) presented +12 in <60% of cells. TTFT and OS for this subgroup were longer than for the subgroup with +12 in ≥60% of cells, with a median TTFT of 49 months (CI95%, 39–58) vs 30 months (CI95%, 22–38) (P = 0.001); and a median OS of 159 months (CI95%, 119–182), vs 96 months (CI95%, 58–134) (P = 0.015). Other factors associated with a shorter TTFT were: Binet stage, B symptoms, lymphadenopathy, splenomegaly, high lymphocyte count, 11q‐, high β2microglobulin, and high LDH. In the multivariate analysis, clinical stage, +12 in ≥60% of cells, high lymphocyte count, B symptoms, and 11q‐ in addition, resulted of significance in predicting shorter TTFT. Significant variables for OS were: Binet stage, lymphadenopathy, splenomegaly, high LDH, high β2microglobulin, 11q‐, and CD38. In the multivariate analysis, only Binet stage, 11q‐, and high β2microglobulin significantly predicted shorter OS. CLL with +12 entails a heterogeneous group with intermediate prognosis. However, a high proportion of cells carrying +12 separates a subgroup of patients with poor outcome. Copyright © 2015 John Wiley & Sons, Ltd.
Zevalin and BEAM (Z‐BEAM) versus rituximab and BEAM (R‐BEAM) conditioning chemotherapy prior to autologous stem cell transplantation in patients with mantle cell lymphoma

AbstractEarly relapse is common in patients with mantle cell lymphoma (MCL) highlighting the unmet need for further improvement of therapeutic options for these patients. CD20 inhibition combined with induction chemotherapy as well as consolidation with high‐dose chemotherapy (HDCT) is increasingly considered cornerstones within current therapy algorithms of MCL whereas the role of radioimmunotherapy is unclear. This retrospective single center study compared 46 consecutive MCL patients receiving HDCT in first or second remission. Thirty‐five patients had rituximab and BEAM (R‐BEAM), and 11 patients received ibritumomab tiuxetan (Zevalin®), an Yttrium‐90 labeled CD20 targeting antibody, prior to BEAM (Z‐BEAM) followed by autologous stem cell transplantation (ASCT). We observed that the 5‐year overall survival (OS) in the R‐BEAM and Z‐BEAM groups was 55% and 71% (p = 0.288), and the 4‐year progression free survival (PFS) was 32% and 41%, respectively (p = 0.300). There were no treatment related deaths in both groups, and we observed no differences in toxicities, infection rates or engraftment. Our data suggest that the Z‐BEAM conditioning regimen followed by ASCT is well tolerated, but was not associated with significantly improved survival compared to R‐BEAM.

Maternal Nurturing Substance and Paternal Spirit: the Making of a Southern Anga Sociality
Authors: BonnemèRe Pascale 
Published: February 2015

ABSTRACTThe present paper attempts to understand what the Ankave‐Anga are saying about gender, kinship and parenthood through the representations that take the human body as a focal point. I try to show that, while representations of bodily substances and procreation do not explicitly deal with patrilineality, they do underlie practices which pertain to the realm of kinship. It is mainly the existence of ties between an individual and his or her mother, and therefore with her kin, that is expressed. These ties appear to be characterized by the sharing of food, conviviality, joy. Overall a strong identity defines individuals linked through the female line. The Ankave, and probably with them other southern Anga groups, appear to be different from the ones already known with respect to ideas about procreation, growth and male maturation.

Shamanism in Northwest Australia
Authors: Lommel Andreas , Mowaljarlai David 
Published: February 2015

Editors' note: Andreas Lommel was Director of the Staatliche Museum für Völkerkunde in Munich from 1957 to 1977. He last did fieldwork in Australia in 1955 with his wife, Katharine, (Lommel and Lommel, 1989), and first in 1939 when he came to the Kimberley district of Western Australia as a member of an ethnological expedition under the auspices of the Frobenius Institute in Frankfurt‐am‐Main. Based on this work, he and another member of the Frobenius expedition, Helmut Petri, have produced ethnographic monographs (Lommel 1952, Petri 1954) and many other publications on the Wunambal and Ngarinyin respectively. The following is one of the few yet to have appeared in English. We have chosen to publish it for the unique perspective it offers on a particular, poignant moment behind the frontiers of European settlement of Aboriginal Australia.For another perspective on some of the same matters, we have paired Lommel's memoir with one by one of the Ngarinyin people he met on the trek he describes in it: David Mowaljarlai, who was at that time about ten years old (as recalled in Lommel's foreword to Mowaljarlai and Malnic, 1993). Mowaljarlai is now a leading figure in Aboriginal affairs, and in 1991 was named Aboriginal Australian of the Year. As it happens, Lommel's manuscript reached Oceania just as one of us (A. R.) was about to leave for the Kimberleys to collaborate on a site survey with Mowaljarlai. We informed Lommel of this and suggested that Mowaljarlai be invited to provide further comments and reminiscences about the matters discussed in the paper. Lommel enthusiastically accepted this offer and raised specific points for clarification from Mowaljarlai, which were put to him and two other senior Ngarinyin men in the interview which is transcribed below.
