Five leaps to corporate sustainability through a corporate responsibility portfolio matrix
Authors: Ketola Tarja 
Published: December 2009

AbstractIs corporate sustainability absolute or relative? Should companies adopt an evolutionary (step‐by‐step) or a revolutionary (one‐leap) approach to sustainable development – or is there a third way? These questions are hot potatoes, which burn the answerer's mouth because of strong opposing views. Yet the potatoes must be eaten now. There is no time to wait for them to cool because by then it may be too late to act. After munching these hot potatoes, an alternative (five‐leap) approach to corporate sustainability is outlined. A portfolio matrix measuring the integration of environmental, sociocultural and economic responsibilities along a five‐leap scale is drafted. This cube can be adapted to measure any company's level of responsibility with the aim of achieving sustainability on a fast track. Copyright © 2009 John Wiley & Sons, Ltd and ERP Environment.
Cytodiagnosis of benign fibrous histiocytoma of rib and diagnostic dilemma: A case report
Authors: Mondal Santosh Kumar 
Published: December 2009

AbstractBenign fibrous histiocytoma (BFH) of bone is rare in occurrence, and rib is an unusual site. There are limited case reports of this entity in the literature, and cytodiagnosis of this tumor is not described. A 24‐year‐old man presented with a firm mass and pain in the right lateral chest wall. Radiological investigations (plain radiograph and computed tomography) revealed a lytic bone lesion involving the 5th rib. Radiologically, giant cell tumor (GCT), BFH, and plasmacytoma were suspected. In fine‐needle aspiration cytology (FNAC), admixture of benign stromal cells and scattered osteoclast type giant cells were found in the smears. Differential diagnoses of BFH, GCT (non‐epiphyseal type), fibrous dysplasia, and aneurysmal bone cyst were made on cytology. Subsequent histologic examination confirmed the diagnosis of BFH. Cytologic diagnosis of BFH of rib is difficult as this tumor may mimic other giant cell containing tumors of bone in FNAC. The final diagnosis should always be made after correlation with histological, radiological, and clinical features. Diagn. Cytopathol. 2010. © 2009 Wiley‐Liss, Inc.
Wnt signaling has different temporal roles during retinal development
Authors: Sánchez‐Sánchez Ana V. , Camp Esther , Leal‐Tassias Aránzazu , Mullor José L. 
Published: December 2009

AbstractDifferentiation of neural retinal precursor (NRP) cells in vertebrates follows an established order of cell‐fate determination associated with exit from the cell cycle. Wnt signaling regulates cell cycle in colon carcinoma cells and has been implicated in different aspects of retinal development in various species. To better understand the biological roles of Wnt in the developing retina, we have used a transgenic and pharmacological approach to manipulate the Wnt signaling pathway during retinal development in medaka embryos. With the use of both approaches, we observed that during the early phase of retinal development Wnt signaling regulated cell cycle progression, proliferation, apoptosis, and differentiation of NRP cells. However, during later phases of retinal development, proliferation and apoptosis were not affected by manipulation of Wnt signaling. Instead, Wnt regulated Vsx1 expression, but not the expression of other retinal cell markers tested. Thus, the response of NRP cells to Wnt signaling is stage‐dependent.

Calmin expression in embryos and the adult brain, and its regulation by all‐trans retinoic acid

Published: December 2009

AbstractThe vitamin A metabolite, all‐trans retinoic acid (atRA), is a regulator of nervous system development. Using a subtracted cDNA library constructed from neuroblastoma cells, the atRA‐responsive gene calmin (Clmn) was identified (Merrill et al. [2004] Biol Chem 385:605‐614). The Clmn transcript is detected very early in rat embryonic development and is sensitive to retinoid status. In vitamin A‐deficient embryos, Clmn mRNA is dramatically down‐regulated in the neuroepithelium adjacent to the somites, and this expression can be rescued with the addition of atRA. In embryonic day 18.5 embryos, CLMN is detected in regions where newly differentiated neurons are found, including the neural retina and the cortical plate; and in the adult brain, CLMN is most highly expressed in the neuron cell bodies of the hippocampus, cerebellum, and olfactory bulb. Thus, Clmn is sensitive to retinoid status during early gestational stages, and its expression is relegated to postmitotic neuronal cells in the adult rat brain.

The tight junction component Claudin E is required for zebrafish epiboly
Authors: Siddiqui Manal , Sheikh Hasan , Tran Christopher , Bruce Ashley E.E. 
Published: December 2009

AbstractZebrafish epiboly results in the thinning and spreading of the blastoderm to cover the yolk cell and close the blastopore. The extra‐embryonic yolk syncytial layer (YSL) tows the blastoderm vegetally during epiboly by means of its tight junction attachments to the enveloping layer (EVL). Claudins are the major transmembrane protein components of tight junctions. Here, we focus on the function of Claudin E (Cldne), which is expressed specifically in the EVL. Morpholino knock‐down of cldne produced a highly penetrant epiboly delay. Our analysis suggested that the EVL margin, which is attached to the YSL, was under reduced tension in morphant embryos. We propose that local variation in the strength of EVL–YSL attachment in morphant embryos resulted in slow and uneven advancement of the EVL and blastoderm. Our work is the first to demonstrate that Claudins are important for zebrafish epiboly. Developmental Dynamics 239:715–722, 2010. © 2009 Wiley‐Liss, Inc.
Science communications: Publishing a scientific paper
Authors: Kiefer Julie C. 
Published: December 2009

AbstractPublications are the lifeblood of academic science. They are essential to the scientific community as records of research completed, building blocks for new research, and templates for new ways of thinking. Publications are also essential for individual job security. Frequently they are considered a gauge of productivity that is taken under heavy consideration for hiring, promotion, and funding decisions. Consequently, completed research is of little value unless preserved in publication. Yet publishing can be a challenging prospect, particularly in the face of abundant competition. Here, five panelists, John Fallon, Ph.D., Min Han, Ph.D., Janet Rossant, Ph.D., Cliff Tabin, Ph.D., and Yoshiko Takahashi, Ph.D., offer their advice on manuscript preparation and negotiating the publishing process.

Comparison of extraembryonic expression of Eomes and Cdx2 in pregastrulation chick and mouse embryo unveils regulatory changes along evolution
Authors: Pernaute Bárbara , Cañon Susana , Crespo Miguel , Fernandez‐Tresguerres Beatriz , Rayon Teresa , Manzanares Miguel 
Published: December 2009

AbstractIn the mouse blastocyst, Eomes and Cdx2 are critical for establishing the trophoectoderm, the precursor of the placenta. To better understand how the trophoectoderm lineage arose in mammals during evolution, we examined the expression of their orthologues in the pregastrulation chick embryo and found that, while both genes are expressed in extraembryonic tissues, their temporal pattern of expression differs from what occurs in mouse. Moreover, we failed to detect expression of other genes specific from the mouse trophoectoderm in extraembryonic regions of the chick. Also unlike the mouse, chick Eomes is expressed in primordial germ cells. Finally, conserved noncoding elements in the Eomes genomic region are unable to drive trophoectoderm restricted expression in the mouse blastocyst, but do so in conserved sites of expression such as the forebrain. These results suggest that critical changes in the gene regulatory networks controlling extraembryonic development accompanied the appearance of the trophoectoderm in mammals.

pHMA, a pH‐sensitive GFP reporter for cell engulfment, in Drosophila embryos, tissues, and cells
Authors: Fishilevich Elane , Fitzpatrick James A. J. , Minden Jonathan S. 
Published: December 2009

AbstractEngulfment of apoptotic cells by phagocytosis ensures the removal of unwanted and defective cells. We developed a genetically encoded marker for cell engulfment, pHMA, which consists of the pH‐Sensitive derivative of GFP, pHluorin, fused to the actin‐binding domain of Moesin. In healthy cells of Drosophila embryos and cultured cells, pHMA resides at the cell cortex. In dying cells, pHMA loses its cortical localization and reports a modest decrease in pH. In embryos, the dying cells lose their apical contacts, then move basally and are ultimately engulfed by neighboring cells or macrophages. The cell corpse material is strongly acidified soon after engulfment and persists in the phagocytic cell for several hours. Changes in the pHMA signal correlate well with increases or decreases in apoptosis. These data show that pHMA is a useful reporter for cell engulfment and can be used in screening for mutations that affect cell engulfment.

Achievement method of high‐speed response of error prediction tracking control for optical disk system
Authors: Hayano Toru , Shibutani Isao , Ohishi Kiyoshi , Miyazaki Toshimasa , Koide Daiichi , Tokumaru Haruki 
Published: December 2009

AbstractThis paper proposes the new design method of error‐prediction control systems combining the ZPET control and the robust feedback control. The error‐prediction control system based on ZPET control can reduce the tracking error caused by periodic disturbances more efficiently than the conventional repetitive control technique. However, the proposed tracking servo system does not reduce the residual tracking error caused by the low‐pass filter of the feedforward compensation and by the long sampling time. In order to overcome this problem, this paper proposes the new structure of the feedforward tracking control system. The modified ZPET control tracking servo system for optical disk recording system does not include the low‐pass filter and its sampling time becomes faster. On the other hand, the sudden disturbance observer reduces the influence of nonperiodic disturbances. The experimental results point out that the proposed tracking servo system has a precise tracking response against both the periodic disturbances and the nonperiodic disturbances. © 2009 Wiley Periodicals, Inc.

Electrical conduction and dielectric relaxation in polyethylene terephthalate succinate
Authors: Kato Fukutaro , Ohki Yoshimichi 
Published: December 2009

AbstractElectrical conduction and complex permittivity are examined in polyethylene terephthalate succinate, focusing on their relations to dielectric relaxation processes. Both the real and imaginary parts of the complex permittivity, namely, the dielectric constant ε′r and the dielectric loss factor ε′′r, increase with a decrease in frequency, especially at high temperatures. They are both ascribed to the transport of ionic mobile carriers. Namely, the carrier transport forms a conduction current that should contribute to ε′′r. On this occasion, if charge exchange does not occur at the two electrodes, heterocharge layers should be formed before the electrodes. This should increase the charge density on the electrodes, thus contributing to ε′r. In addition to the increase in ε′r and ε′′r due to mobile ions, two relaxation processes, one due to micro‐Brownian motion of dipoles and the other due to orientation and magnitude change of the dipole moment induced by two end groups in the polymer main chain, are observed. Corresponding to these two relaxation processes, two thermally stimulated discharge current (TSDC) peaks appear. The two TSDC peaks as well as the increments in ε′r and ε′′r become larger when the crystallinity of the sample decreases. © 2009 Wiley Periodicals, Inc.

Estimating mean life of an aged power equipment group with operation data sequence
Authors: Toyoda Junichi , Sakamoto Kunio , Chida Takuji 
Published: December 2009

AbstractThis paper proposes a systematic method of estimating the mean life of an aged power equipment group based on the approach of Dr. W. Li of BCTC, Canada (IEEE Transactions on Power Systems, February 2004). In order to estimate the mean life of aged power equipment systematically and effectively with the operation data sequence, a linear estimation method is developed on the assumption that the stochastic behavior of aged equipment life determines the probability distribution model, such as the normal model or the Weibull model. Introductory and practical examples are illustrated for verification of the proposed approach. © 2009 Wiley Periodicals, Inc.

A study on video performance of multipoint‐to‐point video streaming with multiple description coding over ad hoc networks
Authors: Utsu Keisuke , Chow Cheeonn , Ishii Hiroshi 
Published: December 2009

AbstractSupporting multimedia applications over wireless networks has become a very active research topic recently because video applications are forecast to receive high demand in future wireless networks, such as ad hoc networks. However, enabling video transmission over wireless ad hoc networks is more challenging than over other wireless networks due to node mobility, interference, and the absence of a supporting infrastructure. This paper addresses the problem of video transmission over ad hoc networks. We propose to combine Multiple Description Coding (MDC) with multiple source transport (Multipoint‐to‐Point transfer: MP2P) in order to maintain smooth video streaming over wireless ad hoc networks. In this paper, we describe a comprehensive simulation and test bed experiment designed to show the effect of the proposed MP2P video transfer with MDC for two description cases of video streaming over wireless ad hoc networks. The results show that the proposed mechanism successfully improves video transfer performance in terms of video packet reachability and throughput. © 2009 Wiley Periodicals, Inc.

International ideal and local practice – access to environmental information and local government in Poland
Authors: Banas Pawel A. 
Published: December 2009

AbstractAccess to information plays an important part in modern governance and is vital for sustainability, as envisaged in Agenda 21, the Aarhus Convention and EU environmental law. Given a shortage of relevant studies dedicated to CEE countries, this paper presents empirical evidence regarding application of the international principle of access to information at the very bottom of administrative hierarchy in one of the largest CEE states. Taking into account the great variety of Polish municipalities with respect to their demographic, economic, environmental and urban characteristics, the paper examines practical access to very basic environmental information. The paper scrutinizes one particular type of information while referring to different modes of accessibility. Survey and interview based data shows to what extent the principle is already adopted at the local level, to what extent e‐government is utilized to secure the provision of information and whether an urban–rural cleavage occurs in this respect.

Frameworks by Solvent‐Free Synthesis of Rare Earth Chlorides with Molten 1,3‐Benzodinitrile and Tailoring of the Particle Size: ∞3[LnCl3{1,3‐C6H4(CN)2}], Ln = Y, Dy, Ho, Er, Yb

Published: December 2009

AbstractThe solvent‐free melt reactions of anhydrous rare earth trichlorides with molten 1,3‐benzodinitrile [1,3‐C6H4(CN)2, C8H4N2] result in isophthalonitrile frameworks of the rare earth elements. The particle size of the products can bevaried from the millimeter to the nanometer scale (down to 50–400 nm) depending on the synthesis conditions. Thus, these network structures are among the very few coordination polymers that can be synthesized as nanoparticles. A constitution of 1:1 concerning LnCl3/1,3‐C6H4(CN)2 is found for Y (1), Dy (2), Ho (3), Er (4), and Yb (5) in isotypic∞3[LnCl3{1,3‐C6H4(CN)2}]. The ligand 1,3‐C6H4(CN)2 functions both as chemical scissors and replaces chloride linkages by degrading the rare earth chloride structures, and subsequently forms new 3D‐framework structures. They consist of strands of chlorido‐coordinated lanthanide atoms, which are linked in two dimensions by 1,3‐C6H4(CN)2 molecules. Compounds 1–5 were obtained as single crystals from the melt reaction, and their crystal structures were determined by single‐crystal X‐ray analysis. They can also be obtained as nanocrystalline materials from a ball mill treatment, identified by electron microscopy (REM) and EDX analysis.
MEKC: A powerful tool for the determination of amino acids in a variety of biomatrices
Authors: Viglio Simona , Fumagalli Marco , Ferrari Fabio , Iadarola Paolo 
Published: December 2009

AbstractThe continued publication from year to year of new MEKC formulations for the analysis of amino acids provides evidence that both CZE and MEKC still have a great power of attraction in this area. The present review intends to cover the literature on MEKC of amino acids from 2007 until present: it has been planned to follow the same format of our previous review (Electrophoresis2008,29, 224–236) representing its ideal continuation. In addition to methodological developments, the more recent practical applications of MEKC procedures for the determination of amino acids in different matrices will also be described here as an evidence, once again, of the suitability of this technique on samples of different origin.

Finally, some future developments that may increase the applicability of coupled SPE‐CE are highlighted.
Influence of runout‐path material on emplacement of the Round Top rock avalanche, New Zealand
Authors: Dufresne A. , Davies T.R. , McSaveney M.J. 
Published: December 2009

AbstractFactors influencing the distance a disintegrating rock mass travels as it spreads across the landscape after detaching from a slope include the volume and mechanical properties of the material, local topography and the materials encountered in the runout path. Here we investigate the influence of runout‐path material on the mobility and final morphology of the Round Top rock avalanche deposit, New Zealand. This rock avalanche of mylonitic schist ran out over a planar surface of saturated fluvial gravel. Longitudinal ridges aligned radial to source grade into smaller aligned hummocks and digitate lobes in the distal reach. Soils and river gravels in the runout path are found bulldozed at elongate ridge termini where they formed local obstacles halting avalanche motion at these locations, thus aiding development of prominent elongate ridges on the deposit. Further travel over the disrupted substrate led to avalanche–substrate mixing at the base of the debris mass. Field observations combined with subsurface geophysical investigations and laboratory analogue models illustrate the processes of substrate deformation features at the Round Top rock avalanche.

Trends in timing of low stream flows in Canada: impact of autocorrelation and long‐term persistence
Authors: Ehsanzadeh Eghbal , Adamowski Kaz 
Published: December 2009

AbstractThe annual timing of river flows might indicate changes that are climate related. In this study, trends in timing of low flows for the Reference Hydrometric Basin Network were investigated under three different hypotheses namely: independence, short‐term persistence (STP) and long‐term persistence (LTP). Both summer and winter time series were characterized with scaling behaviour providing strong evidence of LTP. The Mann–Kendall trend test was modified to account for STP and LTP, and used to detect trends in timing of low flows. It was found that considering STP and LTP resulted in a significant decrease in the number of detected trends. Numerical analysis showed that the timing of summer 7‐day low flows exhibited significant trends in 16, 9 and 7% of stations under independence, STP and LTP assumptions, respectively. Timing of summer low flow shifted toward later dates in western Canada, whereas the majority of stations in the east half of the country (except Atlantic Provinces) experienced a shift toward earlier dates. Timing of winter low flow experienced significant trends in 20, 12, and 6% of stations under independence, STP and LTP assumptions, respectively. Shift in timing of winter low flow toward earlier dates was dominant all over the country where it shifted toward earlier dates in up to 3/4 of time series with significant trends. There are local patterns of upward significant/insignificant trends in southeast, southwest and northern Canada. This study shows that timing of low flows in Canada is time dependent; however, addressing the full complexity of memory properties (i.e. short term vs long term) of a natural process is beyond the scope of this study.
