Clusters identification and characterization in a gas–solid fluidized bed by the wavelet analysis
Authors: Afsahi Forough‐Azam , Sotudeh‐Gharebagh Rahmat , Mostoufi Navid 
Published: May 2009

AbstractThe local solid flow structure of the bubbling fluidized bed of sand particles was investigated in order to identify and characterize the clusters. Extensive experiments were carried out using an optical fibre probe, measuring the velocity and the diameter of clusters. Under all operating conditions, ascending and descending clusters co‐existed at all measurement locations. The locus of the inversion point at which the directions of cluster motion changed was determined. The velocity of the ascending clusters was a function of both superficial gas velocity and the radial and axial position. With increasing superficial gas velocity, both the velocity and the diameter of ascending clusters decreased near the wall. However, the velocity of descending clusters depended mainly on superficial gas velocity and the largest clusters existed closer to the wall. The results of this study help to explain cluster hydrodynamics in fluidized beds.
Protein methylation in full length Chlamydomonas flagella
Authors: Sloboda Roger D. , Howard Louisa 
Published: May 2009

AbstractPost‐translational protein modification occurs extensively in eukaryotic flagella. Here we examine protein methylation, a protein modification that has only recently been reported to occur in flagella [Schneider MJ, Ulland M, Sloboda RD.2008. Mol Biol Cell 19(10):4319–4327.]. The cobalamin (vitamin B12) independent form of the enzyme methionine synthase (MetE), which catalyzes the final step in methionine production, is localized to flagella. Here we demonstrate, using immunogold scanning electron microscopy, that MetE is bound to the outer doublets of the flagellum. Methionine can be converted to S‐adenosyl methionine, which then serves as the methyl donor for protein methylation reactions. Using antibodies that recognize symmetrically or asymmetrically methylated arginine residues, we identify three highly methylated proteins in intact flagella: two symmetrically methylated proteins of about 30 and 40 kDa, and one asymmetrically methylated protein of about 75 kDa. Several other relatively less methylated proteins could also be detected. Fractionation and immunoblot analysis shows that these proteins are components of the flagellar axoneme. Immunogold thin section electron microscopy indicates that the symmetrically methylated proteins are located in the central region of the axoneme, perhaps as components of the central pair complex and the radial spokes, while the asymmetrically methylated proteins are associated with the outer doublets.

Internal Architecture and Adsorption Sites of Violet Lander Molecules Assembled on Native and KBr‐Passivated InSb(001) Surfaces
Authors: Godlewski Szymon , Goryl Grzegorz , Gourdon Andre , Kolodziej Jacek J. , Such Bartosz , Szymonski Marek 
Published: May 2009

AbstractThe adsorption of individual Violet Lander molecules self‐assembled on the c(8×2) reconstructed InSb(001) surface in its native form and on the surface passivated with one to three monolayers of KBr is investigated by means of low‐temperature scanning tunneling microscopy (STM). Preferred adsorption sites of the molecules are found on flat terraces as well as at atomic step edges. For molecules immobilized on flat terraces, several different conformations are identified from STM images acquired with submolecular resolution and are explained by the rotation of the 3,5‐di‐tert‐butylphenyl groups around σ bonds, which allows adjustment of the molecular geometry to the anisotropic substrate structure. Formation of ordered molecular chains is found at steps running along substrate reconstruction rows, whereas at the steps oriented perpendicularly no intermolecular ordering is recorded. It is also shown that the molecules deposited at two or more monolayers of the epitaxial KBr spacer do not have any stable adsorption sites recorded with STM. Prospects for the manipulation of single molecules by using the STM tip on highly anisotropic substrates are also explored, and demonstrate the feasibility of controlled lateral displacement in all directions.
A systematic method for the development of a three‐phase transformer non‐linear model
Authors: Theocharis Andreas D. , Milias‐Argitis John , Zacharias Thomas 
Published: May 2009

AbstractIn this work, a novel three‐phase transformer non‐linear model is developed. The proposed model takes into account the magnetic core topology and the windings connections. The non‐linear characteristic curve of the core material is introduced by its magnetization curve or by its hysteresis loop using the mathematical hysteresis model proposed by Tellinen or the macroscopic hysteresis model proposed by Jiles–Atherton. The eddy currents effects are included through non‐linear resistors using Bertotti's work. The proposed model presents several advantages. An incremental linear circuit, having the same topology with the magnetic circuit of the core, is used in order to directly write the differential equations of the magnetic part of the transformer. The matrix Ld that describes the coupling between the windings of the transformer is systematically derived. The electrical equations of the transformer can be easily written for any possible connection of the primary and secondary windings using the unconnected windings equations and transformation matrices. The proposed methods for the calculation of the coupling between the windings, the representation of the eddy currents and the inclusion of the core material characteristic curve can be used to develop a transformer model appropriate for the EMTP/ATP‐type programs.

A critical step for postsynaptic F‐actin organization: Regulation of Baz/Par‐3 localization by aPKC and PTEN
Authors: Ramachandran Preethi , Barria Romina , Ashley James , Budnik Vivian 
Published: May 2009

AbstractActin remodeling has emerged as a critical process during synapse development and plasticity. Thus, understanding the regulatory mechanisms controlling actin organization at synapses is exceedingly important. Here, we used the highly plastic Drosophila neuromuscular junction (NMJ) to understand mechanisms of actin remodeling at postsynaptic sites. Previous studies have suggested that the actin‐binding proteins Spectrin and Coracle play a critical role in NMJ development and the anchoring of glutamate receptors most likely through actin regulation. Here, we show that an additional determinant of actin organization at the postsynaptic region is the PDZ protein Baz/Par‐3. Decreasing Baz levels in postsynaptic muscles has dramatic consequences for the size of F‐actin and spectrin domains at the postsynaptic region. In turn, proper localization of Baz at this site depends on both phosphorylation and dephosphorylation events. Baz phosphorylation by its binding partner, atypical protein kinase C (aPKC), is required for normal Baz targeting to the postsynaptic region. However, the retention of Baz at this site depends on its dephosphorylation mediated by the lipid and protein phosphatase PTEN. Misregulation of the phosphorylation state of Baz by genetic alterations in PTEN or aPKC activity has detrimental consequences for postsynaptic F‐actin and spectrin localization, synaptic growth, and receptor localization. Our results provide a novel mechanism of postsynaptic actin regulation through Baz, governed by the antagonistic actions of aPKC and PTEN. Given the conservation of these proteins from worms to mammals, these results are likely to provide new insight into actin organization pathways. © 2009 Wiley Periodicals, Inc. Develop Neurobiol 2009
Maternal care effects on SNB motoneuron development: The mediating role of sensory afferent distribution and activity
Authors: Lenz Kathryn M. , Sengelaub Dale R. 
Published: May 2009

AbstractMaternal licking in rats affects the development of the spinal nucleus of the bulbocavernosus (SNB), a sexually dimorphic motor nucleus that controls penile reflexes involved with copulation. Reduced maternal licking produces decreased motoneuron number, size, and dendritic length in the rostral portion of the adult SNB as well as deficits in adult male copulatory behavior. Previous research suggests that decreases in perineal tactile stimulation may be responsible for these effects. To determine whether the regional effects of maternal licking on SNB morphology are driven by sensory afferent innervation of the lumbosacral spinal cord, we used WGA‐HRP to reconstruct the location of sensory afferent fibers from the perineal skin. We found that these fibers are caudally concentrated relative to the area of the SNB dendritic field, with the rostral dendritic arbor receiving little perineal afferent innervation. We also assessed Fos expression following perineal tactile stimulation to determine whether it increased local spinal cord activity in the SNB dendritic field. Sixty seconds of licking‐like perineal stimulation produced a transient 115% increase in Fos expression in the area of the SNB dendritic field. This effect was driven by a significant increase in Fos in the caudal portion of the SNB dendritic field, matching the pattern of perineal afferent fiber labeling. Perineal tactile stimulation also produced significantly greater Fos expression in male pups than in female pups. Together, these results suggest that perineal sensory afferent activity mediates the effects of early maternal care on the masculinization of the SNB and resultant male copulatory behavior. © 2009 Wiley Periodicals, Inc.

European governance of natural resources and participation in a multi‐level context: An editorial
Authors: Rauschmayer Felix , Paavola Jouni , Wittmer Heidi 
Published: May 2009

AbstractPolicy markers are looking at two different directions for guidance when addressing the challenges of multi‐level environmental governance in the face of global environmental change. First, they are seeking scientific advice to find solutions to policy problems. Second, they are emphasizing participation of the public and/or stakeholders to enhance the legitimacy of governance. In this editorial we explore the challenges of participation in a multi‐level governance context, outline a practically relevant strategy for research on multi‐level governance of natural resources and briefly outline the key contributions of the five articles that comprise this special issue. The special issue maps issues of key importance for research on multi‐level governance of natural resources rather than offering conclusions from systematic comparative studies – the latter is the ultimate goal of the GoverNat project from which the contributions stem.

From government to governance for biodiversity: the perspective of central and Eastern European transition countries
Authors: Kluvánková‐Oravská Tatiana , Chobotová Veronika , Banaszak Ilona , Slavikova Lenka , Trifunovova Sonja 
Published: May 2009

AbstractThis paper addresses the problems of institutional changes in governance and the framing of biodiversity conservation policy at the level of the enlarged European Union. The current development of European Union governance has become more complex and multilevel, partially usurping competences from the central state and relying on networks of interconnected actors rather than on a hierarchy dominated and defined by the state. This shift is particularly challenging for biodiversity governance in new member states, where current decision making is still affected by post‐socialist relations and massive ongoing institutional changes, often resulting in inefficient institutional designs and over‐exploitation of natural resources. The paper offers a cross‐country analysis of five Central and Eastern European countries, characterized by different socialist regimes and different transition processes from hierarchical to democratic and market governance. The theoretical basis of the paper is institutional rebuilding in Central and Eastern Europe in the context of the emerging multilevel environmental governance of the EU. The data were collected from desk study research and interviews. The results show that some elements of multilevel governance existed in these countries prior to the transition, but that EU integration empowered lower levels of self‐government. The mismatch between the old hierarchical institutions developed under socialism and the new decentralized institutions introduced during the transformation process still persists and is visible. The emergence of multilevel governance with multiple actors' participation is prone to create tensions, but evidence from the countries studied indicates that this is not necessarily a disadvantage.

Environmental governance: participatory, multi‐level – and effective?
Authors: Newig Jens , Fritsch Oliver 
Published: May 2009

AbstractCurrent political trends and scholarly research increasingly promote collaborative and participatory governance in multi‐level systems as a way to more sustainable and effective environmental policy. Yet empirical findings as well as conceptual works from different academic fields remain ambiguous about this claim. This paper explores whether and to what extent the existence of multiple levels of governance affects the ability of participatory decision‐making to deliver high quality environmental policy output and to improve implementation and compliance. To this end, findings from the literature on multi‐level governance, public participation and policy implementation as well as on complex systems are integrated in five sets of hypotheses. In order to put these to a ‘plausibility probe’, a meta‐analysis of 47 case studies from Northern America and Western Europe is conducted. These cases provide qualitative insights and allow for some generalization in the form of correlation analysis. The study finds that, predominantly, environmental preferences of the involved actors determine the environmental outputs (and outcomes) of decision‐making. Further, face‐to‐face, but not mere two‐way, communication appears to positively influence the ecological standard of decisions. The analysis also suggests that a highly polycentric governance system comprising many agencies and levels of governance yields higher environmental outputs than rather monocentric governance. However, correlations between governance effectiveness and decision‐making scale, as well as policy delivery and institutional fit to ecosystem, could not be identified. The paper concludes by outlining pathways for more systematic comparative research on these pressing research questions. Copyright © 2009 John Wiley & Sons, Ltd and ERP Environment.
Cationic Rhodium(I)/H8‐binap Complex Catalyzed [2+2+2] Cycloadditions of 1,6‐ and 1,7‐Diynes with Carbonyl Compounds (Eur. J. Org. Chem. 17/2009)
Authors: Otake Yousuke , Tanaka Rie , Tanaka Ken 
Published: May 2009

AbstractThe cover picture shows cationic rhodium(I)/H8‐binap complex catalyzed [2+2+2] cycloadditions of 1,6‐ and 1,7‐diynes with carbonyl compounds, leading to dienones. The present rhodium catalysis allows both electron‐rich and electron‐deficient carbonyl compounds, including acyl phosphonates, to be used. In the reactions involving bifunctional carbonyl compounds or unsymmetrical 1,6‐diynes, high chemo‐ or regioselectivities were observed. Details are discussed in the article by K. Tanaka et al. on p. 2737ff.
