AbstractMassBank is the first public repository of mass spectra of small chemical compounds for life sciences (<3000 Da). The database contains 605 electron‐ionization mass spectrometry(EI‐MS), 137 fast atom bombardment MS and 9276 electrospray ionization (ESI)‐MSn data of 2337 authentic compounds of metabolites, 11 545 EI‐MS and 834 other‐MS data of 10 286 volatile natural and synthetic compounds, and 3045 ESI‐MS2 data of 679 synthetic drugs contributed by 16 research groups (January 2010). ESI‐MS2 data were analyzed under nonstandardized, independent experimental conditions. MassBank is a distributed database. Each research group provides data from its own MassBank data servers distributed on the Internet. MassBank users can access either all of the MassBank data or a subset of the data by specifying one or more experimental conditions. In a spectral search to retrieve mass spectra similar to a query mass spectrum, the similarity score is calculated by a weighted cosine correlation in which weighting exponents on peak intensity and the mass‐to‐charge ratio are optimized to the ESI‐MS2 data. MassBank also provides a merged spectrum for each compound prepared by merging the analyzed ESI‐MS2 data on an identical compound under different collision‐induced dissociation conditions. Data merging has significantly improved the precision of the identification of a chemical compound by 21–23% at a similarity score of 0.6. Thus, MassBank is useful for the identification of chemical compounds and the publication of experimental data. Copyright © 2010 John Wiley & Sons, Ltd.
Late‐Pleistocene tidewater glaciers and glaciomarine sequences from north County Mayo, Republic of Ireland
Authors: McCabe A. Marshall , Haynes John R. , Macmillan Nora F. 
Published: July 2010

AbstractLate‐Pleistocene deposits in north County Mayo were deposited in three main glacigenic environments. 1. Drumlins and basal tills were formed when ice moved from the Irish lowlands and local mountain catchments into Donegal Bay. 2. Gilbert‐type deltas accumulated up to 80m I.O.D. on the lowlands and subaqueous moraines formed across minor valleys when marine‐based ice grounded inland. 3. A thick drape of fossiliferous glaciomarine mud along the coastal fringe was deposited from meltwater plumes and by ice‐rafting immediately outside of these ice limits. The muds contain an Elphidium clavatum‐dominated, low‐diversity microfauna which is characteristic of cold‐water conditions adjacent to glacier termini. Valves of Macoma calcarea from the mud have been 14C dated at 16940 ± 120 and 17300 ± 100 BP.The high‐level delta complex was deposited from tidewater glaciers in a peripheral depression adjacent to the drumlin ice limits of north County Mayo. Although the field evidence cannot be used to determine former sea level history with any accuracy, it poses general problems for sea level history and isostatic effects of the last major ice sheet in the west of Ireland. Raised glaciomarine sequences commonly occur in close association with drumlin ice limits elsewhere in Ireland and represent marine transgressions prior to glacial unloading. It is suggested that the magnitudes and patterns of crustal depression are greater and geometrically more complex at the margins of ice sheets in Ireland than hitherto realised.
Polarized Raman and IR spectra of non‐centrosymmetric PbB4O7 single crystal
Authors: Hanuza J. , Ma̧czka M. , Lorenc J. , Kaminskii A. A. , Becker P. , Bohatý L. 
Published: July 2010

AbstractPolarized Raman and IR spectra of a PbB4O7 single crystal were measured. The obtained spectra are discussed within the factor group approach for the orthorhombic P21nm(C2v7) space group with Z = 2 assuming that the crystal structure is built up of the (B4O7)∞2− framework and Pb2+ ions. It has been shown that vibrations of borate and Pb2+ units are observed above 240 and below 160 cm−1, respectively. The results obtained for the spontaneous Raman scattering have also been used in the discussion of the stimulated Raman spectra of the material studied—a new Raman‐laser crystal. The obtained results revealed that mainly translational motions of Pb2+ ions participate efficiently in the SRS effect. Copyright © 2008 John Wiley & Sons, Ltd.
Raman spectroscopic study of the uranyl carbonate mineral čejkaite and its comparison with synthetic trigonal Na4[UO2(CO3)3]
Authors: Čejka Jiří , Sejkora Jiří , Plášil Jakub , Bahfenne Silmarilly , Palmer Sara J. , Frost Ray L. 
Published: July 2010

AbstractRaman and infrared spectroscopies were used to characterise two samples of triclinic čejkaite Na4[UO2(CO3)3] and its synthetic trigonal analogue. The ν3 (UO2)2+ mode is not Raman active, whereas both the ν3 and ν1 (UO2)2+ modes are infrared active. UO bond lengths in uranyls were calculated from the spectra obtained and compared with bond lengths derived from crystal structure analyses. From the higher number of bands related to the uranyl and carbonate vibrations, the presence of symmetrically distinct (UO2)2+ and (CO3)2− units in both structures is proposed.

New insights on surface‐enhanced Raman scattering based on controlled aggregation and spectroscopic studies, DFT calculations and symmetry analysis for 3,6‐bi‐2‐pyridyl‐1,2,4,5‐tetrazine adsorbed onto citrate‐stabilized gold nanoparticles
Authors: de Melo Vitor H. S. , Zamarion Vitor M. , Araki Koiti , Toma Henrique E. 
Published: July 2010

AbstractA systematic study on the surface‐enhanced Raman scattering (SERS) for 3,6‐bi‐2‐pyridyl‐1,2,4,5‐tetrazine (bptz) adsorbed onto citrate‐modified gold nanoparticles (cit‐AuNps) was carried out based on electronic and vibrational spectroscopy and density functional methods. The citrate/bptz exchange was carefully controlled by the stepwise addition of bptz to the cit‐AuNps, inducing flocculation and leading to the rise of a characteristic plasmon coupling band in the visible region. Such stepwise procedure led to a uniform decrease of the citrate SERS signals and to the rise of characteristic peaks of bptz, consistent with surface binding via the N heterocyclic atoms. In contrast, single addition of a large amount of bptz promoted complete aggregation of the nanoparticles, leading to a strong enhancement of the SERS signals. In this case, from the distinct Raman profiles involved, the formation of a new SERS environment became apparent, conjugating the influence of the local hot spots and charge‐transfer (CT) effects. The most strongly enhanced vibrations belong to a1 and b2 representations, and were interpreted in terms of the electromagnetic and the CT mechanisms: the latter involving significant contribution of vibronic coupling in the system.

Cell wall material composition of mealy fruit among ripening nectarines
Authors: Hobbs Michael C , Easterbrook Kathryn M , Melton Laurence D 
Published: July 2010

AbstractNectarines (Prunus persica cv Fantasia) after storage at 2° for 27 days were sampled before and after ripening at 20° for 7 days. The fruit population at 7 days' ripening was divided into two categories. At one extreme there were normally ripe fruit and at the other extreme fruit were mealy. Cell wall material, isolated from the three samples, was separated into CDTA‐ and Na2CO3‐soluble and Na2CO3‐insoluble fractions. A loss of uronic acid from the cell wall material during ripening was observed, but there was no difference between normal and mealy fruit. The neutral sugar content of cell walls was determined by GLC and there was an indication that differences in the relative amount of xylose and galactose existed between normal and mealy fruit. Gel permeation chromatography showed that there were minimal differences in the degree of polymerisation of pectic polymers isolated from normal and mealy fruit.
Effects of beer‐battering on the frying properties of rice and wheat batters and their coated foods
Authors: Shih Fred , Bett‐Garber Karen , Champagne Elaine , Daigle Kim , Lea Jeanne 
Published: July 2010

AbstractBACKGROUND: Beer in batter formulation or beer‐battering has been popular in fried food recipes, but the topic is rarely reported in scientific journals or the claims substantiated with reliable studies. In this research, we prepared and characterized rice and wheat batters with and without using beer to replace water in the formulation. We studied and provided data on the effect of beer on the frying properties of batter and its coated foods.RESULTS: With beer in the formulation, oil uptake of fried batters generally increased by up to 18%. Instrumental textural analyses indicate that beer‐battering treatment generally decreased the hardness, increased the fracturability and improved the crispness of the fried batters. Sensory evaluations show similar trends, though to a lesser extent, that fish and onion rings coated with batters were softer but crispier with beer than without.CONCLUSION: In general, beer‐battering caused an increase in the oil uptake of the batter during frying. It also made the texture of fried batters slightly softer and crispier. The effects are more pronounced for rice batters than wheat batters. Copyright © 2010 Society of Chemical Industry
Iron carburization in CO‐H2‐He gases, Part II: Numerical model
Authors: Wang Zhe , Yetter Richard A. 
Published: July 2010

AbstractA numerical model for the carburization of iron in CO‐H2‐He mixtures was developed and compared with experimental data over the temperature range of 850°C–1150°C, CO partial pressures from 1% to 12%, and H2 partial pressures from 5% to 99%. The reaction mechanism was established on the basis of data input from recent quantum mechanical and molecular dynamics calculations as well as from rate constant estimates from kinetic and transition state theory. Sensitivity and reaction flux analyses were performed to identify the rate‐controlling and fastest reactions. Model predictions of carbon weight gain in iron samples versus time were compared with experimental data. The most sensitive reactions were refined by least‐squares fitting the model to the experiment. The resulting model can simulate and predict the trends of iron carburization in CO‐H2‐He‐CO2‐H2O mixtures for most conditions studied experimentally. Critical reactions and model parameters are identified for additional study to improve the model and understanding of the carburization mechanism. © 2009 Wiley Periodicals, Inc.

Inorganic‐Salt‐Induced Morphological Transformation of Semicrystalline Micelles of PCL‐b‐PEO Block Copolymer in Aqueous Solution
Authors: He Wei‐Na , Xu Jun‐Ting , Du Bin‐Yang , Fan Zhi‐Qiang , Wang Xiaosong 
Published: July 2010

AbstractThe effect of inorganic salt at concentrations typical of a biological environment on the micellar morphology of semicrystalline PCL‐b‐PEO in aqueous solution is investigated. The salt is introduced either by dialysis of a THF solution against an aqueous solution of the salt or by adding it into an aqueous solution containing preformed micelles. The inorganic salt can induce sphere‐to‐rod or sphere‐to‐lamella transformations of the PCL‐b‐PEO micelles in aqueous solution, depending on the length of the PCL block. The inorganic salt induces “salting‐out” of the PEO block, leading to a decrease in the reduced tethering density of the corona in the micelles.magnified image
Homogeneous approximation property for wavelet frames with matrix dilations
Authors: Sun Wenchang 
Published: July 2010

AbstractThe homogeneous approximation property (HAP) for wavelet frames was studied recently. The HAP is useful in practice since it means that the number of building blocks involved in a reconstruction of a function up to some error is essentially invariant under time‐scale shifts. In this paper, we prove the HAP for wavelet frames generated by admissible wavelet functions with arbitrary translation parameters and a class of dilation matrices. Moreover, we show that the approximation is uniform to some extent whenever wavelet functions satisfy moderate smooth and decaying conditions (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Authors: Matsushita Yushu , Hayashida Kenichi , Takano Atsushi 
Published: July 2010

AbstractAmong several star molecules studied so far, the results for two similar but slightly different systems composed of all hydrophobic components, i.e. one low Tg arm and two high Tg arms were compared and discussed mainly. They are polyisoprene‐arm‐polystyrene‐arm‐poly(2‐vinylpyridine) stars and polystyrene‐arm‐polybutadiene‐arm‐poly(2‐vinylpyridine) ones, and are abbreviated as ISP and SBV, respectively, in the original literatures. Several periodic Archimedean tiling patterns can be naturally formed when the relative lengths of three chains are similar one another in both series. Core‐shell type morphologies and actually three‐phase four layer lamellar structures were also commonly observed for two series. A quasicrystalline tiling with dodecagonal symmetry can also be conformed at the targeted composition of ISP/homopolymer blend and a zinc‐blende type structure was created at just a little outside of tiling region for the same blend. Furthermore, the several interesting structures from amphiphilic molecules, composed of a hydrophilic component, poly(ethylene oxide), a hydrophobic component, polymethylmethacrylate and a highly water‐repellent polymer poly(perfluoropropyleneoxide) are described and introduced.

Serial volumetric MRI in Parkinsonian disorders
Authors: Wild Edward J. , Fox Nick C. 
Published: July 2010

AbstractTracking progression in neurodegenerative diseases is hampered by the limitations of the clinical rating scales, which are seldom linear, suffer from floor and ceiling effects, lack the ability to distinguish symptomatic change from disease modification, and are limited by imperfect intra‐ and inter‐rater reliability. The promise of an era of neuroprotective therapies renders urgent the search for reliable measures of progression. Biomarkers have the potential to enhance several aspects of both therapeutic trials and clinical practice. MRI‐based measures of cerebral volume can provide a surrogate for neuronal loss and several techniques have been applied to elucidate disease processes, aid diagnosis, and enable monitoring of progression in a variety of Parkinsonian disorders, including Parkinson's disease, dementia with Lewy bodies, multiple system atrophy, progressive supranuclear palsy and Huntington's disease. We review the approaches to, and findings revealed by, serial volumetric MRI in these disorders. © 2009 Movement Disorder Society

Published: July 2010

AbstractA boundary integral formulation of the linear elasticity problem for a multi‐component composite is given. The fast BEM solver based on the adaptive cross approximation is then obtained by the data‐sparse representation of the resulting Galerkin matrices. The solver is used to obtain effective elastic moduli of fibre and particle reinforced composites in three dimensions by means of the strain energy equivalence principle.

Vasculoprotective potential of olive oil components
Authors: Carluccio Maria Annunziata , Massaro Marika , Scoditti Egeria , De Caterina Raffaele 
Published: July 2010

AbstractEpidemiological and clinical studies found that the traditional Mediterranean‐style diet is associated with significantly lower mortality from coronary artery disease. Although it is difficult to isolate individual dietary factors, cumulative evidence suggests that olive oil, used as primary source of fat by Mediterranean populations, may play a key role in the observed cardiovascular benefit. Olive oil is a priceless source of vitamins and polyphenolic antioxidants, and has a balanced ratio of monounsaturated and polyunsaturated fatty acids. There are multiple mechanisms by which olive oil might impact the development of atherosclerosis. Olive oil decreases LDL‐cholesterol and increases HDL‐cholesterol, and also reduces oxidative stress due to polyphenols, which are able to scavenge free radicals and protect LDL from oxidation. In addition, olive oil components may interfere with the inflammatory response within atherosclerotic lesion, by inhibiting endothelial activation involved in monocyte recruitment during early atherogenesis and macrophage production of inflammatory cytokines and matrix degrading enzymes, thus improving vascular stability. Other vasculoprotective mechanisms by olive oil components derive from anti‐thrombotic and anti‐hypertensive actions. The available data support the need to preserve certain dietary traditions, such as olive oil consumption, to counteract the burden of cardiovascular disease.
Application of new tools for the FDTD analysis of UWB antennas on dielectric substrates

Published: July 2010

AbstractNew techniques are described for the FDTD analysis of radiating structures mounted on infinite planar dielectric substrates. These techniques are the near‐field‐to‐far‐field transform and the total‐field/scattered‐field boundary, or the plane‐wave injector. For demonstrating the use of these techniques, a practical ultra‐wideband antenna on an ungrounded dielectric substrate is analyzed. © 2007 Wiley Periodicals, Inc.

Broad‐Band Reactively Loaded Dipole Antenna
Authors: Einziger P. D. , Leviatan Y. , Rozenkovich J. 
Published: July 2010

AbstractA dipole antenna is an inherently frequency‐sensitive device. The frequency characteristics of the dipole are governed by the current that is induced along the radiating element. Herein, we suggest a design technique of reactive loading, aiming to maintain the current distribution, and consequently the input impedance und the radiation pattern, nearly constant over a wide bond of frequencies. The promising potential of the loading scheme is demonstrated via a moment‐method numerical simulation that shows that even with a single optimal lumped reactive load a notable 5:I bandwidth with VSWR < 3 is attainable.

Published: July 2010

AbstractGonadal function was studied in 15 patients, 12 pubertal or postpubertal, and three prepubertal, who had been treated during childhood for nonmetastatic osteosarcoma of the long bones by chemotherapy regimens that included cis‐platinum and adriamycin. Of seven postpubertal female patients assessed (mean age at diagnosis 16.5 years), three were amenorrhoeic and showed evidence of ovarian damage with raised gonadotrophin levels and a low serum oestradiol concentration. One patient who had regular periods had a raised lutealphase follicle‐stimulating hormone (FSH) concentration suggestive of gonadal dysfunction. Severe oligospermia or reduced testicular volumes in the presence of raised gonadotrophin levels were observed in three of the five pubertal males (mean age at diagnosis 13.25 years). A reliable assessment of gonadal function was not possible in three male patients who remained prepubertal at the time of study. The median total dose of cis‐platinum received by those patients with gonadal damage (median dose, 490 mg) was significantly higher than in those patients with normal gonadal function (median dose, 300 mg) (P = 0.01). In the boys the damage to the testes was primarily directed at the germinal epithelium. Leydig cell function was intact and the males progressed spontaneously through puberty. In the girls, unlike the boys, there was evidence of reversibility of gonadal damage with time. This is the first study to show gonadal dysfunction due to cis‐platinum and adriamycin therapy in childhood.
