Remediation of a historically Pb contaminated soil using a model natural Mn oxide waste

A natural Mn oxide (NMO) waste was assessed as an in situ remediation amendment for Pb contaminated sites. The viability of this was investigated using a 10 month lysimeter trial, wherein a historically Pb contaminated soil was amended with a 10% by weight model NMO. The model NMO was found to have a large Pb adsorption capacity (qmax 346 ± 14 mg g−1). However, due to the heterogeneous nature of the Pb contamination in the soils (3650.54–9299.79 mg kg−1), no treatment related difference in Pb via geochemistry could be detected. To overcome difficulties in traditional geochemical techniques due to pollutant heterogeneity we present a new method for unequivocally proving metal sorption to in situ remediation amendments. The method combines two spectroscopic techniques; namely electron probe microanalysis (EPMA) and X-ray photoelectron spectroscopy (XPS). Using this we showed Pb immobilisation on NMO, which were Pb free prior to their addition to the soils. Amendment of the soil with exogenous Mn oxide had no effect on microbial functioning, nor did it perturb the composition of the dominant phyla. We conclude that NMOs show excellent potential as remediation amendments
Design and synthesis of 1-((1,5-bis(4-chlorophenyl)-2-methyl-1H-pyrrol-3-yl)methyl)-4-methylpiperazine (BM212) and N-Adamantan-2-yl-N'-((E)-3,7-dimethyl-octa-2,6-dienyl)-ethane-1,2-diamine (SQ109) pyrrole hybrid derivatives: discovery of potent anti-tubercular agents effective against multi-drug resistant mycobacteria

Novel pyrroles have been designed, synthesized and evaluated against mycobacterial strains. The pyrroles have originally been designed as hybrids of the anti-tubercular drugs BM212 1 and SQ109 2 that showed common chemical features with very similar topological distribution. A perfect superposition of the structures of 1 and 2 revealed by computational studies suggested the introduction of bulky substituents at the terminal portion of the pyrrole C3 side chain and the removal of the C5 aryl moiety. Five compounds showed high activity toward Mycobacterium tuberculosis, while 9b and 9c were highly active also against multi-drug resistant clinical isolates. Compound 9c showed low eukaryotic cell toxicity, turning out to be an excellent lead candidate for preclinical trials. In addition, four compounds showed potent inhibition (comparable to that of verapamil) towards the whole-cell drug efflux pump activity of mycobacteria, and thus turning to be promising multi-drug resistance reversal agents
S-nitrosation of proteins relevant to Alzheimer's disease during early stages of neurodegeneration

Protein S-nitrosation (SNO-protein), the nitric oxide-mediated posttranslational modification of cysteine thiols, is an important regulatory mechanism of protein function in both physiological and pathological pathways. A key first step toward elucidating the mechanism by which S-nitrosation modulates a protein's function is identification of the targeted cysteine residues. Here, we present a strategy for the simultaneous identification of SNO-cysteine sites and their cognate proteins to profile the brain of the CK-p25-inducible mouse model of Alzheimer's disease-like neurodegeneration. The approach-SNOTRAP (SNO trapping by triaryl phosphine)-is a direct tagging strategy that uses phosphinebased chemical probes, allowing enrichment of SNO-peptides and their identification by liquid chromatography tandem mass spectrometry. SNOTRAP identified 313 endogenous SNO-sites in 251 proteins in the mouse brain, of which 135 SNO-proteins were detected only during neurodegeneration. S-nitrosation in the brain shows regional differences and becomes elevated during early stages of neurodegeneration in the CK-p25 mouse. The SNO-proteome during early neurodegeneration identified increased S-nitrosation of proteins important for synapse function, metabolism, and Alzheimer's disease pathology. In the latter case, proteins related to amyloid precursor protein processing and secretion are S-nitrosated, correlating with increased amyloid formation. Sequence analysis of SNO-cysteine sites identified potential linear motifs that are altered under pathological conditions. Collectively, SNOTRAP is a direct tagging tool for global elucidation of the SNO-proteome, providing functional insights of endogenous SNO proteins in the brain and its dysregulation during neurodegeneration.National Institutes of Health (U.S.) (Grant CA26731)National Institutes of Health (U.S.) (Grant R01 NS051874
A study of boundedness in probabilistic normed spaces(II)

It was shown in Lafuerza-Guillén, Rodríguez-Lallena and Sempi (1999)that uniform boundedness in a Serstnev PN space (V,\un,\tau,\tau^*), named boundedness in the present setting, of a subset A in V with respect to the strong topology is equivalent to the fact that the probabilistic radius R_A of A is an element of D^+.Here we extend the equivalence just mentioned to a larger class of PN spaces, namely those PN spaces that are topological vector spaces (briefly TV spaces), but are not Serstnev PN spaces. We present a characterization of those PN spaces, whether they are TV spaces or not,in which the equivalence holds. Then, a characterization of the Archimedeanmity of triangle function \tau^* of type \tau_{T,L} is given. This work is a partial solution to a problema of comparing the concepts of distributional boundedness (D-bounded in short) and that of boundedness in the sense of associated strong topology
Influence of various process conditions on surface finishes induced by the direct metal deposition laser technique on a Ti–6Al–4V alloy

The direct metal deposition (DMD) with laser is a free-form metal deposition process for manufacturing dense pieces, which allows generating a prototype or small series of near net-shape structures. One of the most critical issues is that produced pieces have a deleterious surface finish which systematically requires post machining steps. This problem has never been fully addressed before.
The present work describes investigations on the DMD process, using an Yb-YAG disk laser, and a widely used titanium alloy (Ti–6Al–4V) to understand the influence of the main process parameters on the surface finish quality. The focus of our work was: (1) to understand the physical mechanisms responsible for deleterious surface finishes, (2) to propose different experimental solutions for improving surface finish.
In order to understand the physical mechanisms responsible for deleterious surface finishes, we have carried out: (1) a precise characterization of the laser beam and the powder stream; (2) a large number of multi-layered walls using different process parameters (P(W), V(m/min), Dm (g/min), Gaussian or uniform beam distribution); (3) a real time fast camera analysis of melt pool dynamics and melt-pool – powder
stream coupling; (4) a characterization of wall morphologies versus process parameters using 2D and 3D profilometry.
The results confirm that surface degradation depends on two distinct aspects: the sticking of nonmelted or partially melted particles on the free surfaces, and the formation of menisci with more or less pronounced curvature radii. Among other aspects, a reduction of layer thickness and an increase of melt-pool volumes to favor re-melting processes are shown to have a beneficial effect on roughness parameters. Last, a simple analytical model was proposed to correlate melt-pool geometries to resulting surface finishes
Foreign banks, profits, market power and efficiency in PICs: some evidence from Fiji

Studies on bank profitability vis-୶is market power and efficiency span a number of years, many countries, regions and methods. Yet, the experiences of the Pacific's small states - where foreign banks are widespread and bank profits relatively high - remain unknown, leaving policy-makers ill-informed regarding relevant policy development. This study fills a huge gap in literature by providing some evidence on the issue in a Pacific Island context. Two market power hypotheses - the structure-conduct-performance (SCP) and the relative market power (RMP) hypotheses together with two measures of the efficient structure (ES) hypothesis - X and scale efficiencies are estimated. The nonparametric data envelopment analysis (DEA) technique is used to estimate efficiency scores for banks in Fiji over the period 2000 to 2010 and the dynamic GMM to estimate the relationships between market power and efficiency vis-୶is profitability. Results show that the RMP and ES hypotheses might hold, but not the SCP. Profits appear to persist over time. Policy implications are considerable including that any suggestions to limit further mergers and acquisitions of banks in the region may have to be properly debated.Griffith Business School, Department of Accounting, Finance and EconomicsFull Tex
Search for extra dimensions using diphoton events in 7 TeV proton-proton collisions with the ATLAS detector ATLAS Collaboration

Using data recorded in 2011 with the ATLAS detector at the Large Hadron Collider, a search for evidence of extra spatial dimensions has been performed through an analysis of the diphoton final state. The analysis uses data corresponding to an integrated luminosity of 2.12 fb−12.12 fb−1 of View the MathML sources=7 TeV proton–proton collisions. The diphoton invariant mass (mγγmγγ) spectrum is observed to be in good agreement with the expected Standard Model background. In the large extra dimension scenario of Arkani-Hamed, Dimopoulos and Dvali, the results provide 95% CL lower limits on the fundamental Planck scale between 2.27 and 3.53 TeV, depending on the number of extra dimensions and the theoretical formalism used. The results also set 95% CL lower limits on the lightest Randall–Sundrum graviton mass of between 0.79 and 1.85 TeV, for values of the dimensionless coupling View the MathML sourcek/M¯Pl varying from 0.01 to 0.1. Combining with previously published ATLAS results from the dielectron and dimuon final states, the 95% CL lower limit on the Randall–Sundrum graviton mass for View the MathML sourcek/M¯Pl=0.01 (0.1) is 0.80 (1.95) TeV.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; ARTEMIS, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNAS, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT, Greece; ISF, MINERVA, GIF, DIP and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; RCN, Norway; MNiSW, Poland; GRICES and FCT, Portugal; MERYS (MECTS), Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MVZT, Slovenia; DST/NRF, South Africa; MICINN, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America.info:eu-repo/semantics/publishedVersio
An algebraic framework for Diffie-Hellman assumptions

The final publication is available at Springer via http://dx.doi.org/10.1007/s00145-015-9220-6We put forward a new algebraic framework to generalize and analyze Di e-Hellman like Decisional Assumptions which allows us to argue about security and applications by considering only algebraic properties. Our D`;k-MDDH assumption states that it is hard to decide whether a vector in G` is linearly dependent of the columns of some matrix in G` k sampled according to distribution D`;k. It covers known assumptions such as DDH, 2-Lin (linear assumption), and k-Lin (the k-linear assumption). Using our algebraic viewpoint, we can relate the generic hardness of our assumptions in m-linear groups to the irreducibility of certain polynomials which describe the output of D`;k. We use the hardness results to  nd new distributions for which the D`;k-MDDH-Assumption holds generically in m-linear groups. In particular, our new assumptions 2-SCasc and 2-ILin are generically hard in bilinear groups and, compared to 2-Lin, have shorter description size, which is a relevant parameter for e ciency in many applications. These results support using our new assumptions as natural replacements for the 2-Lin Assumption which was already used in a large number of applications. To illustrate the conceptual advantages of our algebraic framework, we construct several fundamental primitives based on any MDDH-Assumption. In particular, we can give many instantiations of a primitive in a compact way, including public-key encryption, hash-proof systems, pseudo-random functions, and Groth-Sahai NIZK and NIWI proofs. As an independent contribution we give more e cient NIZK and NIWI proofs for membership in a subgroup of G`. The results imply very signi cant e ciency improvements for a large number of schemes.Peer ReviewedPostprint (author's final draft
Earth-based Render of Tabique Walls–An Experimental Work Contribution

A research work focused on studying earth render for tabique application purposes is presented. Initially, a brief description of the tabique building technique is provided. The relevance of the application of this traditional building technique is also highlighted. Different compositions of earth render are experimentally analyzed and the respective performance is evaluated. Flexural and compressive strengths, workability, drying shrinkage cracking, and water resistance are the material properties assessed. A simple earth render is selected as being adequate for tabique building applications and it is applied on the manufacturing of a tabique wall sample. This wall sample is monitored in terms of thermal insulation ability and its thermal transmission coefficient is estimated. Taking into account that there is still a lack of published technical information related to this topic, this article may contribute to solve this limitation and to give some guidance in future repairing processes of tabique construction. The technological benefit of adding lime or cement with earth is researched. Real tabique timber structure samples are applied in order to validate the obtained experimental results.info:eu-repo/semantics/publishedVersio
Justice and conservation : the need to incorporate recognition

Unidad de excelencia María de Maeztu MdM-2015-0552In light of the Aichi target to manage protected areas equitably by 2020, we ask how the conservation sector should be incorporating concerns for social justice. We focus in particular on ‘recognition’, because it is the leastwell understood aspect of environmental justice, and yet highly relevant to conservation because of its concern with respect for local knowledge and cultures. In order to explore themeaning of recognition in the conservation context, we take four main steps. First, we identify four components of recognition to serve as our analytical framework: subjects of justice, the harms that constitute injustice, themechanisms that produce injustices, and the responses to alleviate these. Secondly, we apply this framework to explore four traditions of thinking about recognition: Hegelian intersubjectivity, critical theory, southern decolonial theory, and the capabilities approach. Thirdly, we provide three case studies of conservation conflicts highlighting how different theoretical perspectives are illustrated in the claims and practices of real world conservation struggles. Fourthly, we finish the paper by drawing out some key differences between traditions of thinking, but also important areas of convergence. The convergences provide a basis for concluding that conservation should look beyond a distributive model of justice to incorporate concerns for social recognition, including careful attention to ways to pursue equality of status for local conservation stakeholders. This will require reflection on working practices and looking at forms of intercultural engagement that, for example, respect alternative ways of relating to nature and biodiversity
Fas ligand elicits a caspase-independent proinflammatory response in human keratinocytes: implications for dermatitis.

Fas ligand (FasL) causes apoptosis of epidermal keratinocytes and triggers the appearance of spongiosis in eczematous dermatitis. We demonstrate here that FasL also aggravates inflammation by triggering the expression of proinflammatory cytokines, chemokines, and adhesion molecules in keratinocytes. In HaCaT cells and in reconstructed human epidermis (RHE), FasL triggered a NF-kappaB-dependent mRNA accumulation of inflammatory cytokines (tumor necrosis factor-alpha, IL-6, and IL-1beta), chemokines (CCL2/MCP-1, CXCL1/GROalpha, CXCL3/GROgamma, and CXCL8/IL-8), and the adhesion molecule ICAM-1. Oligomerization of Fas was required both for apoptosis and for gene expression. Inhibition of caspase activity abolished FasL-dependent apoptosis; however, it failed to suppress the expression of FasL-induced genes. Additionally, in the presence of caspase inhibitors, but not in their absence, FasL triggered the accumulation of CCL5/RANTES (regulated on activation normal T cell expressed and secreted) mRNA. Our findings identify a novel proinflammatory role of FasL in keratinocytes that is independent of caspase activity and is separable from apoptosis. Thus, in addition to causing spongiosis, FasL may play a direct role in triggering and/or sustaining inflammation in eczemas
Dataset concerning the analytical approximation of the Ae3 temperature

The Swift–Hohenberg equation with a nonlocal nonlinearity

It is well known that aspects of the formation of localised states in a one-dimensional Swift–Hohenberg equation can be described by Ginzburg–Landau-type envelope equations. This paper extends these multiple scales analyses to cases where an additional nonlinear integral term, in the form of a convolution, is present. The presence of a kernel function introduces a new lengthscale into the problem, and this results in additional complexity in both the derivation of envelope equations and in the bifurcation structure. When the kernel is short-range, weakly nonlinear analysis results in envelope equations of standard type but whose coefficients are modified in complicated ways by the nonlinear nonlocal term. Nevertheless, these computations can be formulated quite generally in terms of properties of the Fourier transform of the kernel function. When the lengthscale associated with the kernel is longer, our method leads naturally to the derivation of two different, novel, envelope equations that describe aspects of the dynamics in these new regimes. The first of these contains additional bifurcations, and unexpected loops in the bifurcation diagram. The second of these captures the stretched-out nature of the homoclinic snaking curves that arises due to the nonlocal term
On the elliptical flow and asymmetry of the colliding nuclei

A study of elliptical flow is presented with respect to the asymmetry of
colliding nuclei using the reactions of 24Cr50 +44 Ru102, 16S32 +50 Sn120 and
8O16 +54 Xe136 at incident energies between 50 and 250 MeV/nucleon within the
framework of isospin-dependent quantum molecular dynamics model. For the
present analysis, total mass of the colliding pairs is kept fixed and asymmetry
is varied as ? = 0.2, 0.3, 0.7. The elliptical flow shows a transition from
in-plane to out-of-plane in the mid rapidity region with incident energy. The
transition energy is found to increase with the asymmetry for lighter
fragments
Dynamo-driven plasmoid ejections above a spherical surface

We extend earlier models of turbulent dynamos with an upper, nearly
force-free exterior to spherical geometry, and study how flux emerges from
lower layers to the upper ones without being driven by magnetic buoyancy. We
also study how this affects the possibility of plasmoid ejection. A spherical
wedge is used that includes northern and southern hemispheres up to
mid-latitudes and a certain range in longitude of the Sun. In radius, we cover
both the region that corresponds to the convection zone in the Sun and the
immediate exterior up to twice the radius of the Sun. Turbulence is driven with
a helical forcing function in the interior, where the sign changes at the
equator between the two hemispheres. An oscillatory large-scale dynamo with
equatorward migration is found to operate in the turbulence zone. Plasmoid
ejections occur in regular intervals, similar to what is seen in earlier
Cartesian models. These plasmoid ejections are tentatively associated with
coronal mass ejections. The magnetic helicity is found to change sign outside
the turbulence zone, which is in agreement with recent findings for the solar
wind.Comment: 11 pages, 19 figures, accepted in A&
Effective constraint potential in lattice Weinberg - Salam model

We investigate lattice Weinberg - Salam model without fermions for the value
of the Weinberg angle $\theta_W \sim 30^o$, and bare fine structure constant
around $\alpha \sim 1/150$. We consider the value of the scalar self coupling
corresponding to bare Higgs mass around 150 GeV. The effective constraint
potential for the zero momentum scalar field is used in order to investigate
phenomena existing in the vicinity of the phase transition between the physical
Higgs phase and the unphysical symmetric phase of the lattice model. This is
the region of the phase diagram, where the continuum physics is to be
approached. We compare the above mentioned effective potential (calculated in
selected gauges) with the effective potential for the value of the scalar field
at a fixed space - time point. We also calculate the renormalized fine
structure constant using the correlator of Polyakov lines and compare it with
the one - loop perturbative estimate.Comment: LATE
Third rank Killing tensors in general relativity. The (1+1)-dimensional
  case

Third rank Killing tensors in (1+1)-dimensional geometries are investigated
and classified. It is found that a necessary and sufficient condition for such
a geometry to admit a third rank Killing tensor can always be formulated as a
quadratic PDE, of order three or lower, in a Kahler type potential for the
metric. This is in contrast to the case of first and second rank Killing
tensors for which the integrability condition is a linear PDE. The motivation
for studying higher rank Killing tensors in (1+1)-geometries, is the fact that
exact solutions of the Einstein equations are often associated with a first or
second rank Killing tensor symmetry in the geodesic flow formulation of the
dynamics. This is in particular true for the many models of interest for which
this formulation is (1+1)-dimensional, where just one additional constant of
motion suffices for complete integrability. We show that new exact solutions
can be found by classifying geometries admitting higher rank Killing tensors.Comment: 16 pages, LaTe
