Voltammetric discrete current of polyaniline-coated latex particles at microelectrodes

Suspensions of polyaniline-coated latex particles 13 μm in diameter showed the integer-fold
	voltammetric currents at the microelectrode of which size was similar to the diameter of the
	particles. The currents did not vary with concentrations of polyaniline particles but varied
	accidentally with each voltammetric run. They were caused by the reduction of a few
	polyaniline particles adsorbed on the electrode rather than diffusion of polyaniline particles in
	the suspension. The voltammetric behavior was almost the same as at the large electrode
	except for the integer-fold currents. The particle was a nearly mono-dispersed sphere, and was
	composed of a polystyrene core and a polyaniline shell. The particles were dispersed in acidic
	aqueous solution to form a colloidal suspension. The redox charge per particle was 11 G
	redox electrons, one-third of which participated in the voltammetric reduction current
Multiscale description of shale pore systems by scanning SAXS and WAXS microscopy

The pore space of shales and mudrocks ranges from molecular dimensions to micrometers in length scale. This leads to great variation in spatial characteristics across many orders of magnitude, which poses a challenge for the determination of a representative microscopic pore network for such systems. Standard characterization techniques generally provide volume-averaged properties while high-resolution imaging techniques do not assess a representative range of pore sizes because of limitations in the spatial resolution over the field of view. Due to this complexity, open questions remain regarding the role of the pore network in retention and transport processes, which in turn control oil and gas production. Volume-averaged but spatially resolved information is obtained for pores of size from 2 to 150 nm by applying scanning small- and wide-angle X-ray scattering (SAXS and WAXS) microscopy. Scattering patterns are collected in a scanning microscopy mode, such that microvoxels are sampled sequentially, over a total of 2 ?? 2 mm2 raster area on specifically prepared thin sections with a thickness of 10???30 ??m. Spatially resolved variations of porosity, pore-size distribution, orientation, as well as mineralogy are derived simultaneously. Aiming at a full characterization of the shale pore network, the measurements and subsequent matrix porosity analysis are integrated in a multiscale imaging workflow involving FIB-SEM, SEM, and ??-CT analysis
Catalytic Graphitization for Preparation of Porous Carbon Material Derived from Bamboo Precursor and Performance as Electrode of Electrical Double-Layer Capacitor

The combination of the addition of Fe, which acts as catalyst for graphitization, and CO2 activation, which is a kind of gaseous activation, was performed in order to prepare porous carbon material from bamboo powder which is the waste of superheated steam treatment. Regardless of the heat treatment temperature, many macropores were successfully formed by the removal of the Fe compounds after the heating process. The turbostratic carbon structure generated in the Fe-added sample heated at 850 degrees C. It was confirmed that the added Fe acted as the template for pore formation Moreover, It was confirmed that the added Fe acted as the catalyst for graphitization. The electrochemical performances for the electrode of electrical double layer capacitor, such as cyclic voltammetry, electrochemical impedance spectroscopy, and charge-discharge test, could be explained by the effects of the graphitization and activation. The addition of Fe could affect the electrical property of the carbon material derived from bamboo
Minimizing value-at-risk in single-machine scheduling

The vast majority of the machine scheduling literature focuses on deterministic problems in which all data is known with certainty a priori. In practice, this assumption implies that the random parameters in the problem are represented by their point estimates in the scheduling model. The resulting schedules may perform well if the variability in the problem parameters is low. However, as variability increases accounting for this randomness explicitly in the model becomes crucial in order to counteract the ill effects of the variability on the system performance. In this paper, we consider single-machine scheduling problems in the presence of uncertain parameters. We impose a probabilistic constraint on the random performance measure of interest, such as the total weighted completion time or the total weighted tardiness, and introduce a generic risk-averse stochastic programming model. In particular, the objective of the proposed model is to find a non-preemptive static job processing sequence that minimizes the value-at-risk (VaR) of the random performance measure at a specified confidence level. We propose a Lagrangian relaxation-based scenario decomposition method to obtain lower bounds on the optimal VaR and provide a stabilized cut generation algorithm to solve the Lagrangian dual problem. Furthermore, we identify promising schedules for the original problem by a simple primal heuristic. An extensive computational study on two selected performance measures is presented to demonstrate the value of the proposed model and the effectiveness of our solution method
Haploinsufficiency of ARID1B, a Member of the SWI/SNF-A Chromatin-Remodeling Complex, Is a Frequent Cause of Intellectual Disability

Intellectual disability (ID) is a clinically and genetically heterogeneous common condition that remains etiologically unresolved in the majority of cases. Although several hundred diseased genes have been identified in X-linked, autosomal-recessive, or syndromic types of ID, the establishment of an etiological basis remains a difficult task in unspecific, sporadic cases. Just recently, de novo mutations in SYNGAP1, STXBP1, MEF2C, and GRIN2B were reported as relatively common causes of ID in such individuals. On the basis of a patient with severe ID and a 2.5 Mb microdeletion including ARID1B in chromosomal region 6q25, we performed mutational analysis in 887 unselected patients with unexplained ID. In this cohort, we found eight (0.9%) additional de novo nonsense or frameshift mutations predicted to cause haploinsufficiency. Our findings indicate that haploinsufficiency of ARID1B, a member of the SWI/SNF-A chromatin-remodeling complex, is a common cause of ID, and they add to the growing evidence that chromatin-remodeling defects are an important contributor to neurodevelopmental disorders
Formal conceptualisation as a basic for a more procedural knowledge management

Knowledge management at an organisational level can only be brought into practice if a corporate memory is defined. Unfortunately, at this moment there is no complete and procedural specification on how to build it. This paper presents a complete and generic knowledge representation scheme that makes it possible to conceptualise/represent the knowledge of any domain in a systematic way, guiding the definition of a corporate memory and allowing us to reach a more procedural level in knowledge management discipline. The conclusions of our study, which follows the generic and formal definition of any conceptualisation, are illustrated by a real project
Leishmania donovani: thionins, plant antimicrobial peptides with leishmanicidal activity

The leishmanicidal activity of plant antibiotic peptides (PAPs) from the principal families, such wheat thionins, a barley lipid transfer protein and potato defensins and snakins were tested in vitro against Leishmania donovani. Only thionins and defensins were active against this human pathogen at a low micromolar range of concentrations. Thionins resulted as the most active peptides tested until now. They collapsed ionic and pH gradients across the parasite plasma membrane together with a rapid depletion of intracellular ATP without affecting mitochondrial potential. Hence the lethal effect of thionins was mostly associated to permeabilization of the plasma membrane leading to an immediate death of the parasite. The present work is the first evidence for leishmanicidal activity in plant peptides. Future prospects for their development as new antiparasite agents on human diseases are considere
Two-electron temperature model of a laser-driven implosion

The plasma ejected by a pellet irradiated with moderately intense laser light (Icrλ2 ∼1015 W cm−2 μm2, Icr and λ being intensity and wavelength) is analyzed. Both hot electrons caused by resonant absorption, and cold or thermal electrons are considered; no appeal is made to heat‐flux saturation. The cold (hot) population controls the overdense (underdense) plasma flow. Ingoing hot electrons at the critical surface are found to thermalize before reaching the ablation surface. Results obtained are compared with a model that assume one electron temperature, and a saturated flux; agreement requires using a range of saturation factors: 0.1≲f≲0.3. The validity of the model is discussed
Reflectance anisotropy spectroscopy assessment of the MOVPE nucleation of GaInP on Germanium (100)

This work summarizes the observations made on the variation and time evolution of the reflectanceanisotropy signal during the MOVPE growth of GaInPnucleation layers on Germanium substrates. This in situ monitoring tool is used to assess the impact of different nucleation routines and reactor conditions on the quality of the layers grown. This comparison is carried out by establishing a correlation between reflectanceanisotropy signature at 2.1 eV and the morphology of the epilayers evaluated by atomic force microscopy (AFM). This paper outlines the potential of reflectanceanisotropy to predict, explore, and therefore optimize, the best growth conditions that lead to a high quality III–V epilayer on a Ge substrat
A new DSATUR-based algorithm for exact vertex coloring

This paper describes a new exact algorithm PASS for the vertex coloring problem based on the well known DSATUR algorithm. At each step DSATUR maximizes saturation degree to select a new candidate vertex to color, breaking ties by maximum degree w.r.t. uncolored vertices. Later Sewell introduced a new tiebreaking strategy, which evaluated available colors for each vertex explicitly. PASS differs from Sewell in that it restricts its application to a particular set of vertices. Overall performance is improved when the new strategy is applied selectively instead of at every step. The paper also reports systematic experiments over 1500 random graphs and a subset of the DIMACS color benchmark
An Efficient Control of a Series Connected Two-Synchronous Motor 5-Phase with Non Sinusoidal EMF Supplied by a Single 5-leg VSI: Experimental and Theoretical Investigations

Lien vers la version finale éditeur <http://www.sciencedirect.com/science/article/pii/S0378779612001393>This paper proposes the control scheme of an original drive which is made up of two 5-phase permanent magnet synchronous machines (PMSM) connected in series. Even if the Electro-Motive Forces (EMF) are trapezoidal, it is possible, by using a special series connection between the two machines and by implementing a special vector control, to impose independent torques and speeds with a single fiveleg Voltage Source Inverter (VSI). If special series-connection with classical vector control is sufficient to achieve flux/torque decoupling when the EMFs are sinusoidal, it is necessary to modify the control scheme when the EMFs are not sinusoidal. Simulations and experimental results demonstrate the efficiency of the independent control of the two 5-phase synchronous machines connected in series, and the efficiency of the proposed improved control for different loads
Using a pattern-based homogenization scheme for modeling the linear viscoelasticity of nano-reinforced polymers with an interphase

The self-consistent model based on morphological representative patterns is applied to the realistic case of the linear viscoelasticity of polymers reinforced by elastic nano-particles coated with a viscoelastic interphase. This approach allows to study the effect of such microstructure parameters as particle dispersion, particle size distribution and interparticle distance distribution. Under the assumption that the interphase has the same thickness around all reinforcing particles, it is shown that the particle size distribution has little effect on the effective properties of the heterogeneous material,
whereas the particle dispersion and the interparticle distance distribution have stronger impacts
A constitutive model for cyclic actuation of high-temperature shape memory alloys

In this work, a three dimensional constitutive model for High Temperature Shape Memory Alloys (HTSMAs) is presented. To describe the evolution of the cyclic actuation behavior of such alloys, viscoplastic mechanisms and transformation induced plasticity are introduced in addition to the classical transformation behavior of Shape Memory Alloys. Based on contin- uum thermodynamics, the evolution of phase transformation, plasticity induced transforma- tion, retained martensite and viscoplasticity are described. Deformation mechanisms that occur over the operational range of such HTSMAs have been identified from the thermome- chanical behavior of a NiTiPd alloy. The proposed model has therefore been validated based on the prediction of the thermomechanical behavior of the studied NiTiPd HTSMA alloy under di↵erent loading conditions. Careful attention is devoted to the calibration procedure to identify the contribution of the di↵erent mechanisms independently. Finite element anal- ysis (FEA) is performed to demonstrate the capabilities of the model to describe the cyclic behavior of HTSMA devices
A comparative study of reactivity and selectivity of chiral diamines and structurally analogous amino alcohol ligands in enantioselective alkylations with diethylzinc

A series of chiral delta-diamines and structurally analogous delta-amino alcohols derived from natural tartaric acid were synthesized and a comparative study of their activity and selectivity in the enantioselective alkylation of aromatic aldehydes was carried out. Our results show that in general the delta-diamines were found to be better chiral inducers than the corresponding delta-amino alcohols. The highest selectivity was observed when benzaldehyde was alkylated in the presence of the benzylic diamine, giving (R)-1-phenylpropanol with an ee of 42%.

The proteasome regulates the interaction between Cx43 and ZO-1

Gap junction (GJ) intercellular communication (GJIC) is vital to ensure proper cell and tissue function. GJ are multimeric structures composed of proteins called connexins. Modifications on stability or subcellular distribution of connexins have a direct impact on the extent of GJIC. In this study we have investigated the role of the proteasome in regulation of connexin 43 (Cx43) internalization. Although the participation of both the proteasome and lysosome has long been suggested in Cx43 degradation, the molecular mechanisms whereby proteasome contributes to regulate Cx43 internalization and intercellular communication are still unclear. The results presented in this study envision a new mechanism whereby proteasome regulates GJIC by modulating interaction between Cx43 and ZO-1. Immunoprecipitation experiments, in the presence of proteasome inhibitors, together with immunofluorescence data indicate that the proteasome regulates interaction between Cx43 and ZO-1. Overexpression of the PDZ2 domain of ZO-1 and the expression of Cx-43 fused in frame with a V5/HIS tag, suggest that interaction between the two proteins occurs through the PDZ2 domain of ZO-1 and the C-terminus of Cx43. When interaction between Cx43 and ZO-1 is reduced, as in the presence of proteasome inhibitors, Cx43 accumulates, forming large GJ plaques at plasma membrane. Data presented in this article suggest a new pathway whereby alterations in proteasome activity may impact on GJIC as well as on non-junctional communication with extracellular environment, contributing to cell and tissue dysfunction.

Evaluating a bioremediation tool for atrazine contaminated soils in open soil microcosms: The effectiveness of bioaugmentation and biostimulation approaches

A previously developed potential cleanup tool for atrazine contaminated soils was evaluated
in larger open soil microcosms for optimization
under more realistic conditions, using a natural
crop soil spiked with an atrazine commercial formulation (Atrazerba FL). The doses used were 20£ or 200£ higher than the recommended dose (RD) for an agricultural
application, mimicking over-use or spill situations. Pseudomonas sp. strain ADP was used for bioaugmentation (around 107 or 108 viable cells g¡1 of soil) and citrate for biostimulation (up to 4.8 mg g¡1 of soil). Bioremediation treatments providing fastest
and higher atrazine biodegradation proved to differ according to the initial level of soil ontamination. For 20£ RD of Atrazerba FL, a unique inoculation with Pseudomonas sp. ADP (9 ± 1 £ 107 CFU g¡1) resulted in rapid atrazine removal (99% of the initial 7.2 ± 1.6 lg g¡1 after 8 d), independent of citrate.
For 200£ RD, an inoculation with the atrazine-
degrading bacteria (8.5 ± 0.5 £ 107 CFU g¡1) supplemented with citrate amendment (2.4 mg g¡1) resulted in improved biodegradation
(87%) compared with bioaugmentation alone (79%), even though 7.8 ± 2.1 lg of atrazine
g¡1 still remained in the soil after 1 wk. owever, the same amount of inoculum, distributed over three successive inoculations
and combined with citrate, increased  Pseudomonas sp. ADP survival and atrazine
biodegradation (to 98%, in 1 wk). We suggest
that this bioremediation tool may be valuable
for efficient removal of atrazine from  contaminated field soils thus minimizing atrazine and its chlorinated derivatives from reaching water compartments.FEDER, POCI Programme, PPCDT Programme and Fundação para a Ciência e a Tecnologia,

Determination of Mealiness in Apples using Ultrasonic Measurements

A system based on ultrasonic energy absorbance was developed, for non-destructive measurements of three levels of texture degradation towards mealiness in Jonagold and Cox apples. The ultrasonic system comprises a high-power generator and a pair of 80 kHz ultrasonic transducers. One transducer, acting as a transmitter, sends a pulse through the apple tissue, which absorbs part of its energy, depending on internal textural attributes, and the transmitted pulse is received as an emerging signal by the other transducer. The detected ultrasound waves were analysed in parallel with the determination of the mealiness level of the fruit in accordance with destructive measurements in confined compression. The results obtained in Cox apples showed a good correlation between the ultrasound measurements and the confined-compression destructive tests for each mealiness level
Graphic study and geovisualization of the old windmills of La Mancha (Spain)

In Spain, one can find geographical diversity and unique sites of great significance and cultural heritage. Many of the nation’s treasured places, however, have deteriorated or have even disappeared. What is left, then, should be studied and documented both graphically and infographically. It is important to preserve and document Spain’s unique locations, especially those related to vernacular heritage, to transhumance and visual impact assessment in many national infrastructures projects. Windmills are important examples of agro-industrial heritage and are sometimes found in the beds of streams and rivers but can also be found high in the hills. Their presence is constant throughout the Iberian Peninsula. These mills are no longer in use due to technological advances and the emergence of new grinding systems. The aim of this study was to present a specific methodology for the documentation of windmills, to create a graphical representation using computer graphics, as well as to disseminate knowledge of this agro-industrial heritage. This research has integrated graphic materials, including freehand sketches, photographs, digital orthophotos, computer graphics and multimedia in the creation of a specific methodology based on cutting-edge technology such as a digital photogrammetric workstation (DPW), global navigation satellite systems (GNSS), computer-aided design (CAD) and computer animation
Mapping quantitative trait loci (QTLs) associated with dough quality in a soft × hard bread wheat progeny

Bread wheat (Triticum aestivum L.) quality is a key trait for baking industry exigencies and broad consumer preferences. The main goal of this study was to undertake quantitative trait loci (QTL) analyses for bread wheat quality in a set of 79 recombinant inbred lines (RILs) derived from a soft × hard bread wheat cross. Field trials were conducted over two years, utilizing a randomized complete block design. Dough quality was evaluated by sedimentation test, mixograph and alveograph analysis. Protein content was measured by near-infrared reflectance analysis and grain hardness was determined by the single kernel characterization system (SKCS).\ud
A genetic map based on 263 SSR markers and glutenin loci was constructed. Composite interval mapping (CIM) analysis detected a total of 20 QTLs distributed among ten chromosomes which were associated with variations in quality traits.\ud
Results confirmed the previous investigations on the known relationship between storage-protein alleles and dough quality, and detected new and stable QTLs related to dough quality parameters on chromosomes 2A, 7A, 5B and 1D. These new QTLs could be further investigated. Also, in this study, some RILs showed very high dough extensibility values which involve future validation studies for QTLs associated with to this trait
Xyloglucan endotransglucosylase and cell wall extensibility

Transgenic tomato hypocotyls with altered levels of an XTH gene were used to study how XET activity could affect the hypocotyl growth and cell wall extensibility. Transgenic hypocotyls showed significant over-expression (line 13) or co-suppression (line 33) of the SlXTH1 in comparison with the wild type, with these results being correlated with the results on specific soluble XET activity, suggesting that SlXTH1 translates mainly for a soluble XET isoenzyme. A relationship between XET activity and cell wall extensibility was found, and the highest total extensibility was located in the apical hypocotyl segment of the over-expressing SlXTH1 line, where the XET-specific activity and hypocotyl growth were also highest compared with the wild line
Context-sensitive multivariant assertion checking in modular programs

We propose a modular, assertion-based system for  verification and debugging of large logic programs, together with several interesting models for checking assertions statically in modular programs, each with different characteristics and representing different trade-offs. Our proposal is a modular and multivariant extensión of our previously proposed abstract assertion checking model and we also report on its implementation in the CiaoPP system. In our approach, the specification of\ud
the program, given by a set of assertions, may be partial, instead of the complete specification required by raditional verification systems. Also, the system can deal with properties which cannot always be determined at compile-time. As a result, the proposed system needs to work with safe approximations: all assertions proved correct are guaranteed to be valid and all errors actual errors. The use of modular, context-sensitive static analyzers also allows us to introduce a new distinction between assertions checked in a particular context or checked in general
