    2005-01-01

    Comment comprendre la physique ? Comment savoir pourquoi il y a des particules et des antiparticules, ou dans quel état se trouve le chat de Schrödinger ? Comment découvrir ce qui se conserve dans la nature ? Comment s'initier aux théories à la pointe de notre connaissance de l'Univers ? Ce livre veut aider à parler la physique, à apprendre son vocabulaire. Chaque mot est défini dans son sens immédiat comme dans ses significations plus complexes. Et les renvois d'un mot à l'autre permettent de saisir la physique en bloc. Après Les atomes existent-ils vraiment ? et Traité de physique à l'usage des profanes, Bernard Diu fait partager, sous une nouvelle forme, sa passion pour la physique. A le lire, il ne fait aucun doute qu'Einstein avait raison : " Subtil est le Créateur. "

    Sperm motility is one of the most widely used parameters of sperm quality. Computer-aided sperm motility analysis (CASA-Mot) systems were developed to reduce the subjectivity of sperm motility assessment, and have had broad scientific and practical acceptance. In this review, the sources of variation and current applications of this technology and its relationships with other sperm quality tests are described in detail. Despite remarkable advances in the technique, there is still great need for standardisation in many species, and the numerous factors that affect the results make it difficult to provide universally accepted criteria for classifying semen samples based on sperm motility characteristics. The main fields for CASA-Mot include the study of male fertility and pathologies, evaluation of the effects of physical and chemical agents, improvement of epidemiological survey studies, more precise calculation of seminal doses for farm animals, realisation of basic studies about sperm function, improvement of sperm technologies such as cryopreservation and quality control analysis. Numerous relationships have been established between CASA-Mot and other sperm quality tests, although most of these parameters are complementary. Future CASA-Mot systems will probably be able to integrate several sperm quality parameters with motility.

    2007-01-01

    A Cs-133 Magneto-Optical Trap (MOT) has been developed at the Time and Frequency Division of the Centro Nacional de Metrologia, CENAM, in Mexico. This MOT is part of a primary frequency standard based on ultra-cold Cs atoms, called CsF-1 clock, under development at CENAM. In this Cs MOT, we use the standard configuration (σ + - σ - ) 4-horizontal 2-vertical laser beams 1.9 cm in diameter, with 5 mW each. We use a 852 nm, 5 mW, DBR laser as a master laser which is stabilized by saturation spectroscopy. Emission linewidth of the master laser is l MHz. In order to amplify the light of the master laser, a 50 mW, 852 nm AlGaAs laser is used as slave laser. This slave laser is stabilized by light injection technique. A 12 MHz red shift of the light is performed by two double passes through two Acusto-Optic Modulators (AOMs). The optical part of the CENAMs MOT is very robust against mechanical vibration, acoustic noise and temperature changes in our laboratory, because none of our diode lasers use an extended cavity to reduce the linewidth. In this paper, we report results of our MOT characterization as a function of several operation parameters such as the intensity of laser beams, the laser beam diameter, the red shift of light, and the gradient of the magnetic field. We also report accurate absolute measurement of the number of Cs atoms trapped in our Cs MOT. We found up to 6 x 10 7 Cs atoms trapped in our MOT measured with an uncertainty no greater than 6.4%.

  6. An N-terminal Region of Mot-2 Binds to p53 In Vitro

    Full Text Available The mouse mot-2 protein was earlier shown to bind to the tumor suppressor protein, p53. The mot-2 binding site of p53 was mapped to C-terminal amino acid residues 312–352, which includes the cytoplasmic sequestration domain. In the present study, we have found that both mot-1 and mot-2 bind to p53 in vitro. By using His-tagged deletion mutant proteins, the p53-binding domain of mot-2 was mapped to its Nterminal amino acid residues 253–282, which are identical in mot-1 and mot-2 proteins. Some peptides containing the p53-binding region of mot-2 were able to compete with the full-length protein for p53 binding. The data provided rationale for in vitro binding of mot-1 and mot-2 proteins to p53 and supported the conclusion that inability of mot-1 protein to bind p53 in vivo depends on secondary structure or its binding to other cellular factors. Most interestingly, the p53-binding region of mot-2 was common to its MKT-077, a cationic dye that exhibits antitumor activity, binding region. Therefore it is most likely that MKT-077-induced nuclear translocation and restoration of wild-type p53 function in transformed cells takes place by a competitional mechanism.

    Therapeutic targeting bone loss has been the focus of the study in osteoporosis. The present study is intended to evaluate whether MOTS-c, a novel mitochondria related 16 aa peptide, can protect mice from ovariectomy-induced osteoporosis. After ovary removal, the mice were injected with MOTS-c at a dose of 5 mg/kg once a day for 12 weeks. Our results showed that MOTS-c treatment significantly alleviated bone loss, as determined by micro-CT examination. Mechanistically, we found that the receptor activator of nuclear factor-κB ligand (RANKL) induced osteoclast differentiation was remarkably inhibited by MOTS-c. Moreover, MOTS-c increased phosphorylated AMPK levels, and compound C, an AMPK inhibitor, could partially abrogate the effects of the MOTS-c on osteoclastogenesis. Thus, our findings provide evidence that MOTS-c may exert as an inhibitor of osteoporosis via AMPK dependent inhibition of osteoclastogenesis. -- Highlights: •MOTS-c decreases OVX-induced bone loss in vivo. •MOTS-c inhibits RANKL-induced osteoclast formation. •MOTS-c inhibits RANKL-induced osteoclast-specific gene expression. •MOTS-c represses osteoclast differentiation via the activation of AMPK.

  9. Architecture of the bacteriophage T4 activator MotA/promoter DNA interaction during sigma appropriation.

    Gene expression can be regulated through factors that direct RNA polymerase to the correct promoter sequence at the correct time. Bacteriophage T4 controls its development in this way using phage proteins that interact with host RNA polymerase. Using a process called σ appropriation, the T4 co-activator AsiA structurally remodels the σ(70) subunit of host RNA polymerase, while a T4 activator, MotA, engages the C terminus of σ(70) and binds to a DNA promoter element, the MotA box. Structures for the N-terminal (NTD) and C-terminal (CTD) domains of MotA are available, but no structure exists for MotA with or without DNA. We report the first molecular map of the MotA/DNA interaction within the σ-appropriated complex, which we obtained by using the cleaving reagent, iron bromoacetamidobenzyl-EDTA (FeBABE). We conjugated surface-exposed, single cysteines in MotA with FeBABE and performed cleavage reactions in the context of stable transcription complexes. The DNA cleavage sites were analyzed using ICM Molsoft software and three-dimensional physical models of MotA(NTD), MotA(CTD), and the DNA to investigate shape complementarity between the protein and the DNA and to position MotA on the DNA. We found that the unusual "double wing" motif present within MotA(CTD) resides in the major groove of the MotA box. In addition, we have used surface plasmon resonance to show that MotA alone is in a very dynamic equilibrium with the MotA element. Our results demonstrate the utility of fine resolution FeBABE mapping to determine the architecture of protein-DNA complexes that have been recalcitrant to traditional structure analyses.

  11. Rigidity of outermost MOTS: the initial data version

    Galloway, Gregory J.

    2018-03-01

    In the paper Commun Anal Geom 16(1):217-229, 2008, a rigidity result was obtained for outermost marginally outer trapped surfaces (MOTSs) that do not admit metrics of positive scalar curvature. This allowed one to treat the "borderline case" in the author's work with R. Schoen concerning the topology of higher dimensional black holes (Commun Math Phys 266(2):571-576, 2006). The proof of this rigidity result involved bending the initial data manifold in the vicinity of the MOTS within the ambient spacetime. In this note we show how to circumvent this step, and thereby obtain a pure initial data version of this rigidity result and its consequence concerning the topology of black holes.

  12. MOT solution of the PMCHWT equation for analyzing transient scattering from conductive dielectrics

    KAUST Repository

    Uysal, Ismail Enes

    2015-01-01

    Transient electromagnetic interactions on conductive dielectric scatterers are analyzed by solving the Poggio-Miller-Chan-Harrington-Wu-Tsai (PMCHWT) surface integral equation with a marching on-in-time (MOT) scheme. The proposed scheme, unlike the previously developed ones, permits the analysis on scatterers with multiple volumes of different conductivity. This is achieved by maintaining an extra temporal convolution that only depends on permittivity and conductivity of these volumes. Its discretization and computation come at almost no additional cost and do not change the computational complexity of the resulting MOT solver. Accuracy and applicability of the MOT-PMCHWT solver are demonstrated by numerical examples.

    Directory of Open Access Journals (Sweden)

    Ola Zetterquist

    2011-05-01

    Full Text Available The article analyses the fundamental constitutional enigma of the European Union (EU, namely whether the EU can be considered as a (from its Member States separate and independent constitutional legal order. The EU is often referred to as a legal order sui generis, i.e. of a unique character that defies traditional definitions. More specifically, the notion of an independent and separate EU is at odds with the idea of the sovereign state. The notion of the EU as a legal order sui generis is too much influenced by the models of the sovereign state and sovereignty (in the vein of Thomas Hobbes. The key component in the Hobbesian idea of sovereignty is freedom as non-interference. A sovereign state is consequently a state that is free from, i.e. not interfered with by, external actors like, for example, the EU. Put differently, either the EU is sovereign or the Member States are sovereign. By shifting the perspective to a neo-Roman republican understanding of freedom as non-domination the constitutional picture of the EU will become more nuanced. Res publica is best understood as what citizens hold in common and above their narrow self-interest. According to a republican notion of the constitution the purpose of the law is to eliminate the possibility of arbitrary domination. For that reason, not all interference is to be considered as a restriction of freedom but only those restrictions that cannot be justified according to the res publica. Viewed through the republican prism it can be argued that the EU represents an important advancement in securing freedom as non-domination without implying that the EU must become a state. The fundamental enigma can thus be rephrased as a clash between two diverging concepts of freedom. Whereas the EU will always be at odds with the idea of sovereignty (however framed it will be much easier to reconcile with the republican ideal.

During the first phase all necessary components to build the decision support tool have been selected, developed or improved and adapted. At the beginning it was assumed that the contribution of the author's company, Semafor would be the integration of the company's OPAL software components developed for pumps and variable speed drives (VSD) into the EuroDEEM package. In view of the deficiencies of EuroDEEM it was soon agreed to abandon this approach. Instead, the package IMSSA (International Motor Selection and Saving Analysis), developed at the Washington State University on the basis of MotorMaster was selected. IMSSA - which has been renamed to EuroDEEM International - and the pump and VSD module can now be used as standalone applications. The second phase integrated all collected and developed material into a comprehensive and user-friendly web site that was then demonstrated to key actors in the participating countries. Several requirements had to be considered. The platform had to allow the publication of the web pages in several languages and to enable the team members to place and modify their content without disturbing ongoing operation. It was therefore decided to evaluate a suitable Web Content Management System (CMS) which lead to Plone, a powerful and adaptable open-source system already in use at many web sites.

    The Motivation for Traumatic Brain Injury Rehabilitation Questionnaire (MOT-Q) evaluates motivation for rehabilitation in four subscales: Interest in rehabilitation, Lack of anger, Lack of denial, and Reliance on professional help. The objective of this study was to further validate the MOT-Q in 122 inpatients and 92 outpatients with acquired brain injury (ABI). The main measures were motivation for rehabilitation (MOT-Q), self-awareness (Patient Competency Rating Scale), and treatment motivation (Visual Analogue Scale). The MOT-Q showed adequate feasibility in terms of few items with missing responses and few undecided responses. We found no floor or ceiling effects, and significant item-total MOT-Q correlations for 29 of 31 items. Internal consistency was good for the MOT-Q total and acceptable to good for the subscales. The MOT-Q scores were significantly intercorrelated except for the subscales Lack of denial and Reliance on professional help in the inpatient group. The MOT-Q total and subscales were significantly associated with treatment motivation. The Lack of denial subscale showed no significant association with treatment motivation and no to moderate significant associations with self-awareness. In conclusion, the overall MOT-Q is a valid instrument to assess motivation for rehabilitation in patients with ABI. Further research is needed to examine the validity of the subscales.

    The intravascular removal rates of colloidal carbon and of biologically active endotoxin by the reticuloendothelial system (RES) were evaluated as a function of blood-glucose levels. There was a significant negative correlation of carbon clearance half time on blood glucose in both saline-treated and insulin-treated rats. Insulin hypoglycemia depressed RES carbon clearance with the maximal effect occurring at blood glucose values below 30 mg/dl. Insulin hypoglycemia also severely impaired the intravascular removal of endotoxin as evaluated by lethality bioassay in lead-sensitized rats. It is concluded that blood glucose may modulate RES phagocytic function and that the hypoglycemia of endotoxin shock may augment the shock state due to impairment of RES host defense clearance functions.

  9. On the DC loop modes in the MOT solution of the time domain EFIE

    KAUST Repository

    Shi, Yifei

    2014-07-01

    When marching-on-in-time (MOT) method is applied to solve the time domain electric field integral equation (TD-EFIE), DC loop modes are always observed in the solution. In theory these modes should not be observed since they do not satisfy the relaxed initial conditions. Their appearance is attributed to numerical errors. It is shown here that when Rao-Wilton-Glisson basis and Lagrange interpolation functions are used to discretize the TD-EFIE, errors due to this space-time discretization have zero impact on the DC loop modes. Numerical experiments demonstrate that the numerical errors due to approximate solution of the MOT matrix system have more dominant impact on DC loop modes in the MOT solution.

    When marching-on-in-time (MOT) method is applied to solve the time domain electric field integral equation (TD-EFIE), DC loop modes are always observed in the solution. In theory these modes should not be observed since they do not satisfy the relaxed initial conditions. Their appearance is attributed to numerical errors. It is shown here that when Rao-Wilton-Glisson basis and Lagrange interpolation functions are used to discretize the TD-EFIE, errors due to this space-time discretization have zero impact on the DC loop modes. Numerical experiments demonstrate that the numerical errors due to approximate solution of the MOT matrix system have more dominant impact on DC loop modes in the MOT solution.

  11. An Explicit MOT-TD-VIE Solver for Time Varying Media

    Sayed, Sadeed Bin

    2016-03-15

    An explicit marching on-in-time (MOT) scheme for solving the time domain electric field integral equation enforced on volumes with time varying dielectric permittivity is proposed. Unknowns of the integral equation and the constitutive relation, i.e., flux density and field intensity, are discretized using full and half Schaubert-Wilton-Glisson functions in space. Temporal interpolation is carried out using band limited approximate prolate spherical wave functions. The discretized coupled system of integral equation and constitutive relation is integrated in time using a PE(CE)m type linear multistep scheme. Unlike the existing MOT methods, the resulting explicit MOT scheme allows for straightforward incorporation of the time variation in the dielectric permittivity.

    2015-10-26

    A marching on in time (MOT) scheme for solving the Poggio-Miller-Chan-Harrington-Wu-Tsai (PMCHWT) surface integral equation on plasmonic nanostructures is described. The proposed scheme calls for temporal convolutions of the permittivity and Green function of the plasmonic medium with the temporal basis function. Time domain samples of the permittivity and the Green function required by these convolutions are computed using a fast relaxed vector fitting (FRVF) algorithm. Numerical results demonstrate the accuracy and applicability of the proposed MOT-PMCHWT solver.

  14. An MOT-TDIE solver for analyzing transient fields on graphene-based devices

    KAUST Repository

    Shi, Yifei

    2016-11-02

    A marching on-in-time (MOT) scheme for analyzing transient electromagnetic wave interactions on devices consisting of graphene sheets and dielectric substrates is proposed. The MOT scheme discretizes time domain resistive boundary condition (TD-RBC) and Poggio-Miller-Chang-Harrington-Wu-Tsai (TD-PMCHWT) integral equation, which are enforced on the surfaces of the graphene and dielectric substrate, respectively. The expressions of the time domain resistivity and conductivity of the graphene sheet are obtained analytically from the intra-band contribution formulated in frequency domain. Numerical results, which demonstrate the applicability of the proposed scheme, are presented.

  20. RES: Regularized Stochastic BFGS Algorithm

    Science.gov (United States)

    Mokhtari, Aryan; Ribeiro, Alejandro

    2014-12-01

    RES, a regularized stochastic version of the Broyden-Fletcher-Goldfarb-Shanno (BFGS) quasi-Newton method is proposed to solve convex optimization problems with stochastic objectives. The use of stochastic gradient descent algorithms is widespread, but the number of iterations required to approximate optimal arguments can be prohibitive in high dimensional problems. Application of second order methods, on the other hand, is impracticable because computation of objective function Hessian inverses incurs excessive computational cost. BFGS modifies gradient descent by introducing a Hessian approximation matrix computed from finite gradient differences. RES utilizes stochastic gradients in lieu of deterministic gradients for both, the determination of descent directions and the approximation of the objective function's curvature. Since stochastic gradients can be computed at manageable computational cost RES is realizable and retains the convergence rate advantages of its deterministic counterparts. Convergence results show that lower and upper bounds on the Hessian egeinvalues of the sample functions are sufficient to guarantee convergence to optimal arguments. Numerical experiments showcase reductions in convergence time relative to stochastic gradient descent algorithms and non-regularized stochastic versions of BFGS. An application of RES to the implementation of support vector machines is developed.

  1. Does 8-methacryloxyoctyl trimethoxy silane (8-MOTS) improve initial bond strength on lithium disilicate glass ceramic?

    Dental ceramic surfaces are modified with silane coupling agents, such as γ-methacryloxypropyl trimethoxy silane (γ-MPTS), to improve bond strength. For bonding between lithium disilicate glass ceramic and resin cement, the objective was to investigate if 8-methacryloxyoctyl trimethoxy silane (8-MOTS) could yield a similar performance as the widely used γ-MPTS. One hundred and ten lithium disilicate glass ceramic specimens were randomly divided into 11 groups (n=10) according to pretreatment regime. All specimens were pretreated with a different solution composed of one or a combination of these agents: 10 or 20wt% silane coupling agent of γ-MPTS or 8-MOTS, followed by a hydrolysis solution of acetic acid or 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP). Each pretreated surface was luted to a stainless steel rod of 3.6mm diameter and 2.0mm height with resin cement. Shear bond strength between ceramic and cement was measured after 24-h storage in 37°C distilled water. 8-MOTS produced the same bonding performance as γ-MPTS. Both silane coupling agents significantly increased the bond strength of resin cement, depending on their concentration. When activated by 10-MDP hydrolysis solution, 20wt% concentration produced the highest values (γ-MPTS: 24.9±5.1MPa; 8-MOTS: 24.6±7.4MPa). Hydrolysis with acetic acid produced lower bond strengths than with 10-MDP. Silane coupling pretreatment with 8-MOTS increased the initial bond strength between lithium disilicate glass ceramic and resin cement, rendering the same bonding effect as the conventional γ-MPTS.

    The detection of functional motifs is an important step for the determination of protein functions. We present here a new web server SA-Mot (Structural Alphabet Motif) for the extraction and location of structural motifs of interest from protein loops. Contrary to other methods, SA-Mot does not focus only on functional motifs, but it extracts recurrent and conserved structural motifs involved in structural redundancy of loops. SA-Mot uses the structural word notion to extract all structural motifs from uni-dimensional sequences corresponding to loop structures. Then, SA-Mot provides a description of these structural motifs using statistics computed in the loop data set and in SCOP superfamily, sequence and structural parameters. SA-Mot results correspond to an interactive table listing all structural motifs extracted from a target structure and their associated descriptors. Using this information, the users can easily locate loop regions that are important for the protein folding and function. The SA-Mot web server is available at http://sa-mot.mti.univ-paris-diderot.fr.

    A novel bioactive peptide, mitochondrial-derived peptide (MOTS-c), has recently attracted attention as a potential prevention or therapeutic option for obesity and type 2 diabetes mellitus (T2DM). MOTS-c profiles have not yet been reported in human obesity and T2DM. We aimed to determine circulating MOTS-c levels in obesity and explore the association between MOTS-c levels and various metabolic parameters. In this case-control study, 40 obese children and adolescents (27 males) and 57 controls (40 males) were recruited in the Hubei Province of China in 2017. Circulating MOTS-c levels were measured, clinical data (e.g., glucose, insulin and lipid profile) were recorded, and anthropometric measurements were performed. Finally, we investigated correlations between MOTS-c levels and related variables. MOTS-c levels were significantly decreased in the obese group compared with the control group (472.61 ± 22.83 ng/mL vs. 561.64 ± 19.19 ng/mL, p c levels were significantly decreased in obese male children and adolescents compared to their counterparts (465.26 ± 24.53 ng/mL vs. 584.07 ± 21.18 ng/mL, p 0.05). Further, MOTS-c levels were negatively correlated with body mass index (BMI), BMI standard deviation score, waist circumference, waist-to-hip ratio, fasting insulin level, HOMA-IR, and HbA1c in the male cohort. Circulating MOTS-c levels were decreased in obese male children and adolescents and correlated with markers of insulin resistance and obesity. This article is protected by copyright.

  11. An explicit MOT-TDVIE scheme for analyzing electromagnetic field interactions on nonlinear scatterers

    KAUST Repository

    Ulku, Huseyin Arda

    2015-02-01

    An explicit marching on-in-time (MOT) based time domain electric field volume integral equation (TDVIE) solver for characterizing electromagnetic wave interactions on scatterers with nonlinear material properties is proposed. Discretization of the unknown electric field intensity and flux density is carried out by half and full Schaubert-Wilton-Glisson basis functions, respectively. Coupled system of spatially discretized TDVIE and the nonlinear constitutive relation between the field intensity and the flux density is integrated in time to compute the samples of the unknowns. An explicit PE(CE)m scheme is used for this purpose. Explicitness allows for \\'easy\\' incorporation of the nonlinearity as a function only to be evaluated on the right hand side of the coupled system of equations. A numerical example that demonstrates the applicability of the proposed MOT scheme to analyzing electromagnetic interactions on Kerr-nonlinear scatterers is presented. © 2015 IEEE.

  12. On spurious resonant modes in the MOT solution of time domain EFIE

    KAUST Repository

    Shi, Yifei

    2013-07-01

    Theoretically, internal resonant modes should not be induced in the marching-on-in-time (MOT) solution of the time domain electric field integral equation since zero initial conditions are enforced at the beginning of time marching and the internal resonant modes do not satisfy these initial conditions. However, these spurious modes are always observed in the MOT solution. It has been conjectured in the past that numerical errors might establish the necessary initial conditions and allow the incident field to induce the internal resonant modes. Systematic numerical experiments carried out in this work prove this conjecture by demonstrating that the internal resonant modes\\' amplitudes are indeed dictated by the numerical errors and the spectrum of the incident field. © 2013 IEEE.

    2017-01-01

    An explicit marching-on-in-time (MOT) scheme for solving the time domain electric field volume integral equation (TD-EFVIE) on nonlinear and dispersive scatterers is described. The unknown electric field intensity, electric flux density, and polarization densities representing Kerr nonlinearity along with Lorentz dispersion relation, all of which are induced inside the scatterer upon excitation, are expanded using half and full Schaubert-Wilton-Glisson functions in space. The TD-EFVIE and the constitutive relations between polarization, field, and flux terms are cast in the form of a first-order ordinary differential equation. The resulting matrix system is integrated in time using a predictor-corrector scheme to obtain the time dependent unknown expansion coefficients. The resulting MOT scheme is explicit and accounts for nonlinearity by simple function evaluations.

    This paper presents design of a novel modular lower-limb gait exoskeleton built within the FP7 BioMot project. Exoskeleton employs a variable stiffness actuator in all 6 joints, a directional-flexibility structure and a novel physical humanrobot interfacing, which allows it to deliver the required output while minimally constraining user's gait by providing passive degrees of freedom. Due to modularity, the exoskeleton can be used as a full lower-limb orthosis, a single-joint orthosis in any of the three joints, and a two-joint orthosis in a combination of any of the two joints. By employing a simple torque control strategy, the exoskeleton can be used to deliver user-specific assistance, both in gait rehabilitation and in assisting people suffering musculoskeletal impairments. The result of the presented BioMot efforts is a low-footprint exoskeleton with powerful compliant actuators, simple, yet effective torque controller and easily adjustable flexible structure.

  17. A unitary ESPRIT scheme of joint angle estimation for MOTS MIMO radar.

    Wen, Chao; Shi, Guangming

    2014-08-07

    The transmit array of multi-overlapped-transmit-subarray configured bistatic multiple-input multiple-output (MOTS MIMO) radar is partitioned into a number of overlapped subarrays, which is different from the traditional bistatic MIMO radar. In this paper, a new unitary ESPRIT scheme for joint estimation of the direction of departure (DOD) and the direction of arrival (DOA) for MOTS MIMO radar is proposed. In our method, each overlapped-transmit-subarray (OTS) with the identical effective aperture is regarded as a transmit element and the characteristics that the phase delays between the two OTSs is utilized. First, the measurements corresponding to all the OTSs are partitioned into two groups which have a rotational invariance relationship with each other. Then, the properties of centro-Hermitian matrices and real-valued rotational invariance factors are exploited to double the measurement samples and reduce computational complexity. Finally, the close-formed solution of automatically paired DOAs and DODs of targets is derived in a new manner. The proposed scheme provides increased estimation accuracy with the combination of inherent advantages of MOTS MIMO radar with unitary ESPRIT. Simulation results are presented to demonstrate the effectiveness and advantage of the proposed scheme.

    2018-03-09

    Although a relatively high number of sperm quality biomarkers have been reported over the years in several fish species, sperm motility is nowadays considered the best biomarker for fish spermatozoa. The first scientific reports focusing on fish sperm motility date from a century ago, but the objective assessment allowed by computer-aided sperm analysis (CASA-Mot) systems was not applied to fish species until the mid-1980s. Since then, a high number of sperm kinetic parameters from more than 170 fish species have been reported in more than 700 scientific articles, covering a wide range of topics, such as sperm physiology, sperm storage, broodstock management, the phenomenon of sperm competition, ecotoxicology and understanding the life cycle of the species. The sperm kinetic parameters provided by CASA-Mot systems can serve as powerful and useful tools for aquaculture and ecological purposes, and this review provides an overview of the major research areas in which fish sperm motility assessment by a CASA-Mot system has been used successfully.

  4. SlyA regulates motA and motB, virulence and stress-related genes under conditions induced by the PhoP-PhoQ system in Dickeya dadantii 3937.

    2015-01-01

    We previously showed that SlyA of Dickeya dadantii 3937 plays an important role in virulence toward plants, and that the ΔslyA mutant is hypermotile, whereas flagellum synthesis and flagellin production are indistinguishable from the wild type. Here we show that motility factors, including the distance of continuous directed movement, time for that movement and speed, were significantly higher in the ΔslyA mutant than in the wild type. Remarkably, transcription levels of motA and motB, that are involved in flagellar rotation, were elevated in the ΔslyA mutant, suggesting that the mutant's hypermotility was due to an increase in flagellar rotation. In low (10 μM) magnesium medium that activates the PhoP-PhoQ system, growth and virulence of the ΔslyA mutant were much lower than for the wild type; expression of motA, motB, mgtA, pelA, pelB, pelC, pelD, pelE, pelI, indA, tolC, sodC, acsA and hrpN were also reduced in the mutant. Interestingly, motA, motB, pelD, pelE, pelI, sodC and indA were also reduced in phoP and phoQ mutants. Because the SlyA protein directly binds to the promoter region of PhoP, SlyA regulates virulence by controlling multiple pathogenicity-related genes directly and/or at least by controlling PhoP in D. dadantii 3937 when magnesium is low.

  7. Simulation of a 3D MOT-Optical Molasses Hybrid for Potassium-41 Atoms

    Peterson, W. A.; Wrubel, Jonathan

    2017-04-01

    We report a design and numerical model for a 3D magneto-optical trap (MOT)-optical molasses hybrid for potassium-41 atoms. In this arrangement, the usual quadrupole magnetic field is replaced by an octupole field. The octupole field has a central region of very low magnetic field where our simulations show that the atoms experience an optical molasses, resulting in sub-doppler cooling not possible in a quadrupole MOT. The simulations also show that the presence of the magneto-optical trapping force at the edge of the cooling beams provides a restoring force which cycles atoms through the molasses region. We plan to use this hybrid trap to directly load a far off-resonance optical dipole trap. Because the atoms are recycled for multiple passes through the molasses, we expect a higher phase-space density of atoms loaded into the dipole trap. Similar hybrid cooling schemes should be relevant for lithium-6 and lithium-7, which also have poorly resolved D2 hyperfine structure.

    Full Text Available The main objective of this paper is to investigate the household willingness to pay (WTP for improved solid waste management in Thu Dau Mot city, Binh Duong by using Dichotomons choice Contingent Valuation Method. A questionnaire was designed to draw a sample of 330 respondents for the study. The results show that mean household willingness to pay for solid waste management system in Thu Dau Mot is about 24 thousand VND/ month/ household, higher than the current fee (20 thousand VND month/ household.The paper used a logistic regression to establish the factor affecting to the household willingness to pay for solid waste management system. The logit results show that those with a higher income and more educated is willing to pay more for improvement in management of their solid waste. Also, more environmental aware the person the more they are willing to pay. Moreover, females are less likely to give a positive response to WTP compare to male.

    Full Text Available The purpose was to determine the level of agreement between the Motoriktest für Vier- bis Sechsjährige Kinder [MOT 4-6] and the Movement Assessment Battery for Children [M-ABC]. 48 preschool children participated in the study (Mean age = 5 years, 6 months, SD = 3 months. There was high classification agreement (90% between both tests. A Kappa correlation coefficient (0.67 provided moderately strong support for convergent validity. Less agreement was shown in identification of motor difficulties (58%. This was reflected by lower correlation coefficients on the fine movement cluster and test item level. The MOT 4-6 showed values within the range of similar movement skill performance assessment protocols. Because of its specific focus it may be of meaningful value to assess movement skill competence in typically developing preschool children (ages 4 to 6.

  11. Crystallographic and molecular dynamics analysis of loop motions unmasking the peptidoglycan-binding site in stator protein MotB of flagellar motor.

    Cyril F Reboul

    Full Text Available BACKGROUND: The C-terminal domain of MotB (MotB-C shows high sequence similarity to outer membrane protein A and related peptidoglycan (PG-binding proteins. It is believed to anchor the power-generating MotA/MotB stator unit of the bacterial flagellar motor to the peptidoglycan layer of the cell wall. We previously reported the first crystal structure of this domain and made a puzzling observation that all conserved residues that are thought to be essential for PG recognition are buried and inaccessible in the crystal structure. In this study, we tested a hypothesis that peptidoglycan binding is preceded by, or accompanied by, some structural reorganization that exposes the key conserved residues. METHODOLOGY/PRINCIPAL FINDINGS: We determined the structure of a new crystalline form (Form B of Helicobacter pylori MotB-C. Comparisons with the existing Form A revealed conformational variations in the petal-like loops around the carbohydrate binding site near one end of the β-sheet. These variations are thought to reflect natural flexibility at this site required for insertion into the peptidoglycan mesh. In order to understand the nature of this flexibility we have performed molecular dynamics simulations of the MotB-C dimer. The results are consistent with the crystallographic data and provide evidence that the three loops move in a concerted fashion, exposing conserved MotB residues that have previously been implicated in binding of the peptide moiety of peptidoglycan. CONCLUSION/SIGNIFICANCE: Our structural analysis provides a new insight into the mechanism by which MotB inserts into the peptidoglycan mesh, thus anchoring the power-generating complex to the cell wall.

    Full Text Available The residual effect of natural insecticides was evaluated on adults of Sitophilus zeamais Mots. (Coleoptera: Curculionidae on stored corn grains. Clove (Syzygium aromaticum L., white pepper (Piper nigrum L., neem (Azadirachta indica A. Juss and silica dioxide powders were tested as well as neem, eucalyptus (Eucaliptus globulus Labill and Eucaliptus citriodora Hook., eugenol, andiroba (Carapa guianensis Aubl., rosemary (Lippia gracillis HBK., cedar (Cedrela fissilis Vell. and pequi (Caryocar brasiliense Camb. oils. Powders were tested at concentration of 1kg/t in 50g-corn-plot and the oils at dosage of 50¿L in 20g-corn-plot. The plots infestation was accomplished using 20 and 8 adults (males and females of S. zeamais being 0 to 15 days old, respectively, in the experiments with powders and oils. Silica dioxide caused 46.7, 38.3 and 37.5% of mortality, respectively, in the initial (soon after the treatment with the powders or oils and at 60 and 120 days of storage periods, but the mortality induced by the other powders was inexpressive. In the three studied storage periods, silica dioxide was the more efficient in reducing adults emergency. At the initial storage period, all the oils caused mortality above 79%, however, after 60 and 120 days, mortality was lower than 2.5%. The adult emergency increased as stored period increased, although at 120 days the best performance was obtained using neem, followed by andiroba, cedar, rosemary and E. globulus oils.

    For over 30 years, CASA-Mot technology has been used for kinematic analysis of sperm motility in different mammalian species, but insufficient attention has been paid to the technical limitations of commercial computer-aided sperm analysis (CASA) systems. Counting chamber type and frame rate are two of the most important aspects to be taken into account. Counting chambers can be disposable or reusable, with different depths. In human semen analysis, reusable chambers with a depth of 10µm are the most frequently used, whereas for most farm animal species it is more common to use disposable chambers with a depth of 20µm . The frame rate was previously limited by the hardware, although changes in the number of images collected could lead to significant variations in some kinematic parameters, mainly in curvilinear velocity (VCL). A frame rate of 60 frames s-1 is widely considered to be the minimum necessary for satisfactory results. However, the frame rate is species specific and must be defined in each experimental condition. In conclusion, we show that the optimal combination of frame rate and counting chamber type and depth should be defined for each species and experimental condition in order to obtain reliable results.

The plot was infested with eight 0 to 15 days-old S. zeamais adults. The E. globulus, eugenol, rosemary, and neem oils caused 100% mortality in S. zeamais adults. Except for copaiba, all oils caused mortality above 87% and the reduction in emergence of 100%. In the free-choice tests, arenas consisting of two plastic containers symmetrically interconnected to a central box by two plastic tubes were used. Twenty grams of non-treated corn (control were placed in one of the boxes and the same amount of grain treated with 50¿L of each oil comprised the other treatment. Sixteen non-sexed S. zeamais adults (0-15 days old were released in the central box. The rosemary, E. citriodora, eugenol and copaiba oils were the most repellent for S. zeamais adults, with repellence percentage varying from 97.3 to 87.7. Rosemary, andiroba, neem, and cedar reduced S. zeamais emergence in 100%, while the reduction caused by the other oils ranged from 72.7 to 97.9%.

  17. Contraintes de taille dans les mots composés : quand la phonologie entre en concurrence avec les contraintes morphologiques

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available Cette communication porte sur les contraintes phonologiques qui pèsent sur la formation des mots construits dans le cadre théorique de la morphologie lexématique (Anderson 1992, Aronoff 1994, Fradin 2003. En étudiant les données du français, les travaux de Lignon (à paraître, Plénat (2009 & Roché (2003 ont montré que des contraintes de taille étaient à l’œuvre dans plusieurs constructions morphologiques. L’objectif de cet article est d’étudier cette hypothèse sur les mots composés Verbe-Nom du français (Villoing 2009. L’analyse quantitative des données du corpus montre clairement que les verbes des mots composés VN du français sont soumis à des contraintes de taille et doivent répondre au format d’un monosyllabe. La contrainte pèse moins lourdement sur les noms qui parviennent à s’imposer plus facilement que les verbes avec une taille supérieure. Cependant, la majorité des mots composés VN tend à ne pas dépasser trois syllabes (leur format optimal étant de deux ou trois syllabes, révélant ainsi l'influence des contraintes de taille sur le mot composé lui-même. La mise au jour de ces contraintes permet d'expliquer l’absence de certains verbes dans le corpus de composés VN, répondant pourtant bien aux propriétés sémantiques attendues : les verbes construits par affixation (absence de suffixés en -iser, -ifier; très rares cas de préfixés, les verbes du 2ème groupe, les verbes de taille supérieure à trois syllabes. En outre, cet article met au jour un cas de concurrence entre contrainte morphologique et contrainte phonologique au sein d'une construction morphologique, et montre comment la première l'emporte sur la dernière, bien que la contrainte phonologique contraigne fortement le choix du verbe et du nom de base. Il donne également à voir comment la contrainte phonologique parvient néanmoins à influencer le choix de bases sémantiquement peu conformes aux attentes de la règle.

    Full Text Available La maquette du journal occupe une place particulière dans le continuum de fabrication de l’information. Elle est située à l’interface de la matérialité du journal entre la salle de rédaction et le secteur du prépresse. Les discours et les prérogatives dont elle est capable de se charger font qu’elle porte en elle un potentiel stratégique organisationnel important. La maquette du journal demeure pourtant un acteur méconnu de la sociologie des médias. Cette étude, qui se situe au carrefour de la sociologie interactionniste et de la théorie de l’acteur-réseau, propose de donner toute sa place à la maquette et à ceux qui la construisent et l’utilisent au quotidien dans le journal. Nous montrons que c’est entre deux acteurs particuliers et leurs manières différenciées d’être à ce qu’ils font que la maquette est susceptible de révéler tout son potentiel : les journalistes secrétaires de rédaction (SR et les ouvriers typographes. Nous tentons tout d’abord de saisir pourquoi ces trois acteurs (maquette, SR et typographes sont demeurés invisibles au sein du journal. Il s’agit donc de repenser leur place et leur rôle, de les révéler au prisme d’une grille d’observation renouvelée, agrandie. Nous sommes ensuite en mesure d’observer la manière dont ces trois acteurs peuvent interagir, peuvent s’attacher au sein du processus de fabrication de l’information. Pour cela, nous développons trois exemples issus d’un travail de terrain au sein d’un titre de presse quotidienne régionale (PQR. Il s’agit en fait de comprendre les manières dont les journalistes SR et les ouvriers typographes sont plus ou moins parvenus — selon les époques retenues, et de manière non linéaire — à se saisir de l’objet maquette, pour faire ce qui est à faire — le journal — au plus près de la manière dont ils souhaitent le faire. The newspaper layout has a special place in the continuum of news

    This paper presents the preliminary results of the project BRAVO (Brain computer interfaces for Robotic enhanced Action in Visuo-motOr tasks). The objective of this project is to define a new approach to the development of assistive and rehabilitative robots for motor impaired users to perform complex visuomotor tasks that require a sequence of reaches, grasps and manipulations of objects. BRAVO aims at developing new robotic interfaces and HW/SW architectures for rehabilitation and regain/restoration of motor function in patients with upper limb sensorimotor impairment through extensive rehabilitation therapy and active assistance in the execution of Activities of Daily Living. The final system developed within this project will include a robotic arm exoskeleton and a hand orthosis that will be integrated together for providing force assistance. The main novelty that BRAVO introduces is the control of the robotic assistive device through the active prediction of intention/action. The system will actually integrate the information about the movement carried out by the user with a prediction of the performed action through an interpretation of current gaze of the user (measured through eye-tracking), brain activation (measured through BCI) and force sensor measurements. © 2011 IEEE

  17. Electricity market models and RES integration: The Greek case

    International Nuclear Information System (INIS)

    Simoglou, Christos K.; Biskas, Pandelis N.; Vagropoulos, Stylianos I.; Bakirtzis, Anastasios G.

    2014-01-01

    This paper presents an extensive analysis of the Greek electricity market for the next 7-year period (2014–2020) based on an hour-by-hour simulation considering five different RES technologies, namely wind, PV, small hydro, biomass and CHP with emphasis on PV integration. The impact of RES penetration on the electricity market operation is evaluated under two different models regarding the organization of the Greek wholesale day-ahead electricity market: a mandatory power pool for year 2014 (current market design) and a power exchange for the period 2015–2020 (Target Model). An integrated software tool is used for the simulation of the current and the future day-ahead market clearing algorithm of the Greek wholesale electricity market. Simulation results indicate the impact of the anticipated large-scale RES integration, in conjunction with each market model, on specific indicators of the Greek electricity market in the long-term. - Highlights: • Analysis of the Greek electricity market for the next 7-year period (2014–2020) based on hour-by-hour simulation. • Five different RES technologies are considered with emphasis on PV integration. • A power pool (for 2014) and a power exchange (for 2015–2020) are considered. • Various market indicators are used for the analysis of the impact of the RES integration on the Greek electricity market. • Two alternative tariff schemes for the compensation of the new ground-mounted PV units from 2015 onwards are investigated

  18. Resistance of irradiated and non-irradiated corn grain genotypes against the weevil Sitophilus zeamais Mots., 1855 (Coleoptera: Curculionidae)

    Oliveira, Carolina Natali de

    2005-01-01

    The resistance of 13 /////com grain genotypes was evaluated against the attack of Sitophilus zeamais (Mots.) by means of a no-choice test; 6 of them were selected (AGN 2012, AGN 30AOO, AGN 31A31, AGN 25A23, AGN 32A43, and AGN 35A42) and then submitted to a free-choice test where attractiveness and non preference for oviposition were assessed. The grain from the selected genotypes were later treated with Cobalt-60 gamma radiation at the doses of 0.0; 0.5; 1.0; and 1.5 kGy and submitted to the same tests. Based on the results, it was verified that genotypes AGN 2012 (30.6 eggs), AGN 31A31 (33.6 eggs), and AGN 30AOO (34.8 eggs) showed a non-preference for oviposition type of resistance, while non-preference for feeding and/or antibiosis were observed in the first two genotypes only. Genotypes AGN 25A23, AGN 32A43, and AGN 35A42 were the most susceptible to com weevil. The increasing gamma radiation ( 60 Co) doses reduced the mean mass of adults in genotype AGN 2012; however, the same parameter increased in genotype AGN 35A42; when treated at the dose of 1.5 kGy, genotypes AGN 2012 and AGN 31A31 showed a reduction in their mean masses of adults, while genotypes AGN 30AOO and AGN 35A42 showed higher mean mass of adults values. The increasing gamma radiation doses ( 60 Co) provided a reduction in mean grain dry mass consumed by the weevil; however, it was concluded that irradiation did not break com grain resistance and can be used for S. zeamais disinfestation prior to storage.

  19. Intricate Resonant Raman Response in Anisotropic ReS2.

    The strong in-plane anisotropy of rhenium disulfide (ReS 2 ) offers an additional physical parameter that can be tuned for advanced applications such as logic circuits, thin-film polarizers, and polarization-sensitive photodetectors. ReS 2 also presents advantages for optoelectronics, as it is both a direct-gap semiconductor for few-layer thicknesses (unlike MoS 2 or WS 2 ) and stable in air (unlike black phosphorus). Raman spectroscopy is one of the most powerful characterization techniques to nondestructively and sensitively probe the fundamental photophysics of a 2D material. Here, we perform a thorough study of the resonant Raman response of the 18 first-order phonons in ReS 2 at various layer thicknesses and crystal orientations. Remarkably, we discover that, as opposed to a general increase in intensity of all of the Raman modes at excitonic transitions, each of the 18 modes behave differently relative to each other as a function of laser excitation, layer thickness, and orientation in a manner that highlights the importance of electron-phonon coupling in ReS 2 . In addition, we correct an unrecognized error in the calculation of the optical interference enhancement of the Raman signal of transition metal dichalcogenides on SiO 2 /Si substrates that has propagated through various reports. For ReS 2 , this correction is critical to properly assessing the resonant Raman behavior. We also implemented a perturbation approach to calculate frequency-dependent Raman intensities based on first-principles and demonstrate that, despite the neglect of excitonic effects, useful trends in the Raman intensities of monolayer and bulk ReS 2 at different laser energies can be accurately captured. Finally, the phonon dispersion calculated from first-principles is used to address the possible origins of unexplained peaks observed in the Raman spectra, such as infrared-active modes, defects, and second-order processes.

    Increasing physical activity (PA) brings many health benefits, but engaging people in higher levels of PA after their 60s is not straightforward. The Functional Fitness MOT (FFMOT) is a new approach which aims to raise awareness about the importance of components of fitness (strength, balance, flexibility), highlight benefits of PA, engages older people in health behavior change discussions, and directs them to local activity resources. This battery of tests combined with a brief motivational interview has not been tested in terms of feasibility or effectiveness. To assess whether the FFMOT, provided in a health care setting, is appealing to older patients of a community physiotherapy service and to understand the views and perceptions of the older people undergoing the FFMOT regarding the intervention, as well as the views of the physiotherapy staff delivering the intervention. Secondary aims are to assess the feasibility of carrying out a phase 2 pilot randomized controlled trial of the FFMOT, in the context of a community physiotherapy service, by establishing whether enough patients can be recruited and retained in the study, and enough outcome data can be generated. A mixed-methods feasibility study will be conducted in two physiotherapy outpatient clinics in the United Kingdom. A total of 30 physically inactive, medically stable older adults over the age of 60 will be provided with an individual FFMOT, comprising a set of six standardized, validated, age-appropriate tests aimed at raising awareness of the different components of fitness. The results of these tests will be used to provide the participants with feedback on performance in comparison to sex and age-referenced norms. This will be followed by tailored advice on how to become more active and improve fitness, including advice on local opportunities to be more active. Subsequently, participants will be invited to attend a focus group to discuss barriers and motivators to being more active, health

    The most recent EU member states seem to have important Renewable Energy Sources (RES) potential. However, they have serious structural difficulties in development and integration of RES policies. Indeed, the balanced development of RES between the member states is urgent today. The penetration of the RES in these member states is related to the existence of an appropriate environment (political, economical, social, and technological). The current paper is based on an analytical review and specific PEST analysis aiming to assess the current RES environment and the progress so far in each of these most recent EU members. (author)

  13. Les querelles de mots dans le discours politique : modèle d’analyse et étude de cas à partir d’une polémique sur le mot « rigueur » Verbal Disputes in Political Discourse: A Model of Analysis and a Case Study of a Controversy over the Word “Rigueur”

    Full Text Available L’objectif de cet article est de contribuer à la description d’un type particulier d’affrontement qui met régulièrement aux prises les acteurs politiques dans l’espace médiatique contemporain : la querelle de mots. Dans ce genre de cas, un mot particulier est érigé en objet du désaccord, sous l’effet d’un travail de cadrage médiatique opéré par les journalistes : les acteurs politiques sont amenés à prendre position quant à son usage et à justifier leur prise de position au moyen d’arguments. On esquisse un modèle d’analyse de ces querelles de mots et l’on teste ce modèle sur un corpus de discours constitué à partir d’une polémique ayant opposé plusieurs acteurs politiques français autour du mot « rigueur » entre mai et juillet 2010. Sur le plan méthodologique, la démarche se situe à la croisée de la linguistique, des théories de l’argumentation et des sciences de la communication et des médias : elle articule l’étude des formes du métalangage ordinaire à celle du fonctionnement argumentatif des discours et des enjeux contemporains de la médiatisation du politique.This paper aims to contribute to the description of a particular type of confrontation, often taking place between political actors in contemporary media, namely verbal disputes. In such confrontations, a particular word becomes the very object of disagreement. Under the effect of a framing process led by journalists, political actors are invited to take a stand as to whether the word should or should not be used and to justify their position by means of arguments. I propose a model of analysis for verbal disputes, and I test it using a data set composed of a controversy involving several French political actors over the use of the word “rigueur” between May and July, 2010. Methodologically, this paper is influenced by linguistics, argumentation theory and media studies. The paper is focused on describing forms of

    Full Text Available Fremmedspråkfaget har lenge hatt et todelt formål: Det skal ha en nytteverdi, først og fremst i form av kommunikative ferdigheter, og det skal ha en allmenndannende funksjon, bl.a. gjennom tilegnelse av kunnskap om kultur og samfunn i målspråksområdet. Fra og med læreplanen for fremmedspråk i Kunnskapsløftet (2006 er det også tydelig uttrykt at dannelsesdimensjonen omfatter utvikling av interkulturell kompetanse. Denne artikkelen drøfter hvordan fagets todelte formål vil kunne forstås og realiseres i fremmedspråksundervisningen fram mot 2030. Drøftingen tar utgangspunkt i en analyse av dagens situasjon, der trenden med å stykke opp lærestoffet i håndterbare enheter og å vektlegge sterkest det som kan måles mest presist, kan gjøre at ikke-målbar kompetanse som interkulturell dannelse får en relativt svak posisjon. Det argumenteres for at pågående endringer i samfunnsutviklingen og i europeisk utdanningspolitikk vil kunne åpne for en jevnere balanse mellom nytte- og dannelsesperspektivet i faget i fremtiden. Blant disse endringene er 1 en dreining mot et mer holistisk kunnskapssyn, 2 en stadig økende heterogenitet i elevmassen, 3 større bredde i fremmedspråkstilbudet og 4 et økt fokus på flerspråklighet. Artikkelen ser nærmere på disse fire endringsprosessene og diskuterer på hvilken måte de kan og bør påvirke fortolkningen av fremmedspråkfagets todelte formål i årene som kommer.

  17. Making cities energy efficient. Urban and regional planning adopting RES

    Energy Technology Data Exchange (ETDEWEB)

    Ahonen, A.-M.; David, T.; Dorfner, J. [and others

    2013-06-01

    This report summarises the outcomes of a 30 months duration continuing education project entitled 'Urban Planners with Renewable Energy Skills' (UP-RES). The project was carried out by a multi-disciplinary international consortium with the aim of informing planners and related professionals about energy-efficient and CO{sub 2} reducing technologies, practices and systems that can be developed across urban areas to serve whole communities. This report provides an overview of the key issues: The overall project approach to devising a training program based on preceding training needs analysis The key tasks involved in creating the training materials The marketing of the training as well as evaluation results Best practise examples of RES in urban planning. The UP-RES project has focused on several major target groups. These include those groups directly involved in taking forward renewable energy projects for whom the UP-RES training was principally focused; those who wish to deliver such training programmes; and policy makers who are ultimately responsible for the decisions that govern how widely such technologies will be implemented. Each of these groups has its own perspective concerning renewable energy technologies so the report is structured accordingly: For professionals involved in implementation: Among those professions that are likely to become involved with renewable energy initiatives in urban areas are urban planners, architects, energy suppliers, developers, building owners, and consulting engineers. For these professionals chapters 3.2 (summary of training need analysis) and 4 (best practise examples) are most likely to appeal. For training experts and organisations: Training programmes that address the relevance of renewable energies in urban areas require a comprehensive set of materials. As an example of how to organise training courses and lessons learnt, chapter 3 might be interesting. For the generally interested: Renewable energies are

    International Nuclear Information System (INIS)

    The massive deployment of renewable energy sources represents a high priority for Greece in order to comply with the Directive 2009/28/EC on the promotion of the use of energy from renewable sources by 2020. In this perspective, Aegean islands especially Lesvos, are endowed with a considerable potential of a portfolio of renewables, a fact that the entrepreneurial interest has already been targeted. However, regulatory attempts for a massive penetration of renewables do not take seriously into account preferences and risk perceptions of local communities where the proposed projects are to be installed. The aim of this study is to investigate individual preferences and social values towards specific technologies of renewables in Lesvos island. We apply an open-ended contingent valuation survey in order to analyze factors shaping public attitudes towards a portfolio of renewable technologies and estimate the economic welfare (Willingness To Pay) of the preferred technologies. We argue that such information is relevant for energy policy design and the establishment of effective measures for the promotion of renewable energy sources. - Highlights: ► We investigate individual preferences and attitudes towards a portfolio of RES technologies. ► We elicit public acceptance for investing in specific RES technologies. ► We analyze factors shaping public preferences of the preferred technologies. ► We estimate the economic welfare of the preferred technologies

    2012-01-01

    masculinity and horsemanship conveys the impression that women had nothing to do with horses. This is true for many situations. The circus arena, however, seems to have been an exception as women could perform there. At the heart of the performances was not only equestrianism, but also the notion of gender......The purpose of this article is to analyse gender relations in equestrianism from the beginning of the 19th to the first decades of the 20th century. Focus will be on the female horse riding circus artists, the écuyères. The fact that women were circus riders at this time is interesting as in many....... It is even likely that ”doing gender” was an indispensable part of the show, as the allure of the écuyères depended on the embodiment and presentation of seemingly incompatible features: beauty, grace and femininity as well as mastery of an art that was a traditionally male domain....

    Bishop, Jeffery; Barina, Rachelle; Stahl, Devan

    2013-01-01

    The stories in this issue of Narrative Inquiry in Bioethics demonstrate two important things. First these stories explore the space between bodily impairment and the social structures that both enable and constrain the flourishing of those who are differently embodied. The authors of these narratives resist the dominant biomedical interpretation of their impairments, but also demonstrate their dependency upon others--social, medical, or familial others. Second, in writing these narratives, the authors are also engaged in an act of identity formation, which sometimes challenge and sometimes embrace the label of disability. By telling their stories in the middle of the action of their lives--in media res, taking up or resisting the label of disability-they also demonstrate the way in which lives can be lived open to new possibilities and interpretations.

    décrire. Pourtant les mots ne se laissent pas facilement saisir sur l’axe de temps et l’auteur du dictionnaire se trouve souvent devant un dilemme difficile à résoudre. Quelle quantité de mots vieux et livresques doit être présente dans sa nomenclature? Est-ce qu’un mot nouveau qu’il avait recensé sera vraiment intégré au lexique de la langue décrite ? Le but de ce travail est donc d’essayer de répondre à ces questions, d’analyser la présence du lexique de ces deux types dans neuf grands dictionnaires bilingues, parus en Lituanie entre 2000 et 2006, et, enfin, définir leur rôle dans leurs macrostructures. On propose également certaines recommandations générales qui pourraient aider les futurs rédacteurs des dictionnaires à mieux équilibrer le lexique de différents types.

    The introduction of a High-Resolution (Hi-Res) scan mode and another associated option that combines Hi-Res mode with the so-called High Definition (HD) reconstruction kernels (referred to as a Hi-Res/HD mode in this paper) in some multi-detector CT (MDCT) systems offers new opportunities to increase spatial resolution for some clinical applications that demand high spatial resolution. The purpose of this work was to quantify the in-plane spatial resolution along both the radial direction and tangential direction for the Hi-Res and Hi-Res/HD scan modes at different off-center positions. A technique was introduced and validated to address the signal saturation problem encountered in the attempt to quantify spatial resolution for the Hi-Res and Hi-Res/HD scan modes. Using the proposed method, the modulation transfer functions (MTFs) of a 64-slice MDCT system (Discovery CT750 HD, GE Healthcare) equipped with both Hi-Res and Hi-Res/HD modes were measured using a metal bead at nine different off-centered positions (0-16 cm with a step size of 2 cm); at each position, both conventional scans and Hi-Res scans were performed. For each type of scan and position, 80 repeated acquisitions were performed to reduce noise induced uncertainties in the MTF measurements. A total of 15 reconstruction kernels, including eight conventional kernels and seven HD kernels, were used to reconstruct CT images of the bead. An ex vivo animal study consisting of a bone fracture model was performed to corroborate the MTF results, as the detection of this high-contrast and high frequency task is predominantly determined by spatial resolution. Images of this animal model generated by different scan modes and reconstruction kernels were qualitatively compared with the MTF results. At the centered position, the use of Hi-Res mode resulted in a slight improvement in the MTF; each HD kernel generated higher spatial resolution than its counterpart conventional kernel. However, the MTF along the

    2012-01-01

    Drawing from relevant experiences in power systems around the world, this paper offers a review of existing policy support mechanisms for RES-E, with a detailed analysis of their regulatory implications. While recent studies provide an account of current RES-E support systems, in this paper we focus on some of the impacts these mechanisms have on the overall energy market structure and its performance. Given the rising importance of RES-E in systems everywhere, these impacts should no longer be overlooked. - Highlights: ► This paper offers a critical review of RES-E support mechanisms and their regulatory implications. ► The discussion focuses on how the different schemes impact the performance of the energy markets. ► We propose to redesign of current RES-E mechanisms to optimize incentives and market performance. ► Our recommendation is also to gradually move from price-based mechanisms to auctions.

  17. RES hyperphagocytosis by rats with streptozotocin-induced diabetes mellitus.

    Science.gov (United States)

    Cornell, R P

    1981-03-01

    In contrast to previous studies of neutrophils from diabetic animals and humans in vitro and of macrophages from diabetic humans in vivo, which reported phagocytic depression, reticuloendothelial system (RES) hyperphagocytosis of colloidal carbon was observed in rats at 14 and 28 days after diabetes induction with streptozotocin (STZ). Carbon clearance half times were significantly enhanced to 6.3 +/- 0.79 and 8.1 +/- 1.04 min at 14 and 28 days post-STZ, respectively, compared with the nondiabetic value (12.7 +/- 0.98 min). The severity of uncontrolled STZ-induced diabetes in rats was confirmed by significant hypoinsulinemia, hyperglucagonemia, hyperglycemia, and hyperlipidemia. Although body weights of STZ-diabetic animals declined progressively, liver weights as a percent of body weight increased above the control value at 14 and 28 days post-STZ. In fact, expression of carbon phagocytosis as the corrected phagocytic index, which accounts for changes in liver and spleen weights relative to body weight, eliminated the significant difference between STZ-diabetic and nondiabetic animals. Antibiotic treatment of diabetic rats failed to alter the hyperphagocytosis, implying that a chronic bacterial infection was not the cause of phagocytic stimulation. Daily insulin replacements, but not a single large insulin dose to 14-day post-STZ rats, reversed the enhanced phagocytosis of colloidal carbon.

    The paper presents the design features, the energy modelling and optical performance details of two pilot Intelligent Energy Buildings, (IEB). Both are evolution of the Zero Energy Building (ZEB) concept. RES innovations backed up by signal processing, simulation models and ICT tools were embedded into the building structures in order to implement a new predictive energy management concept. In addition, nano-coatings, produced by TiO2 and ITO nano-particles, were deposited on the IEB structural elements and especially on the window panes and the PV glass covers. They exhibited promising SSP values which lowered the cooling loads and increased the PV modules yield. Both pilot IEB units were equipped with an on-line dynamic hourly solar radiation prediction model, implemented by sensors and the related software to manage effectively the energy source, the loads and the storage or the backup system. The IEB energy sources covered the thermal loads via a south façade embedded in the wall and a solar roof which consists of a specially designed solar collector type, while a PV generator is part of the solar roof, like a compact BIPV in hybrid configuration to a small wind turbine.

  20. Cardiovascular Small Heat Shock Protein HSPB7 Is a Kinetically Privileged Reactive Electrophilic Species (RES) Sensor.

    Small heat shock protein (sHSP)-B7 (HSPB7) is a muscle-specific member of the non-ATP-dependent sHSPs. The precise role of HSPB7 is enigmatic. Here, we disclose that zebrafish Hspb7 is a kinetically privileged sensor that is able to react rapidly with native reactive electrophilic species (RES), when only substoichiometric amounts of RES are available in proximity to Hspb7 expressed in living cells. Among the two Hspb7-cysteines, this RES sensing is fulfilled by a single cysteine (C117). Purification and characterizations in vitro reveal that the rate for RES adduction is among the most efficient reported for protein-cysteines with native carbonyl-based RES. Covalent-ligand binding is accompanied by structural changes (increase in β-sheet-content), based on circular dichroism analysis. Among the two cysteines, only C117 is conserved across vertebrates; we show that the human ortholog is also capable of RES sensing in cells. Furthermore, a cancer-relevant missense mutation reduces this RES-sensing property. This evolutionarily conserved cysteine-biosensor may play a redox-regulatory role in cardioprotection.

    By performing density functional theory-based calculations, we investigate how structural, electronic and mechanical properties of single layer ReS2 can be tuned upon hydrogenation of its surfaces. It is found that a stable, fully hydrogenated structure can be obtained by formation of strong S-H bonds. The optimized atomic structure of ReS2H2 is considerably different than that of the monolayer ReS2 which has a distorted-1T phase. By performing phonon dispersion calculations, we also predict that the Re2-dimerized 1T structure (called 1T {{}\\text{R{{\\text{e}}2}}} ) of the ReS2H2 is dynamically stable. Unlike the bare ReS2 the 1T {{}\\text{R{{\\text{e}}2}}} -ReS2H2 structure which is formed by breaking the Re4 clusters into separated Re2 dimers, is an indirect-gap semiconductor. Furthermore, mechanical properties of the 1T {{}\\text{R{{\\text{e}}2}}} phase in terms of elastic constants, in-plane stiffness (C) and Poisson ratio (ν) are investigated. It is found that full hydrogenation not only enhances the flexibility of the single layer ReS2 crystal but also increases anisotropy of the elastic constants.

    Full Text Available Despite quite similar conditions (natural resources for electricity production from renewable energy sources (RES-E in three Baltic States (Estonia, Latvia and Lithuania, significant differences exist in these countries as to the RES-E production volume. In Latvia this volume is the highest, while in Estonia and Lithuania it is half as high. One of the factors that determine the RES-E production volumes is support policies, which in the Baltic States are different. The main objective of this work was to analyze and compare these support policies. The results have shown that for rapid RES-E development the most effective policy is to be market-oriented (as in Estonia, whereas for more stable development such policy should be producer-oriented (as in Lithuania.

    In order to achieve cost-effective RES-E deployment it is often argued that technology-neutral support schemes for renewables are indispensable. Against this background, RES-E support policies making widely use of technology differentiation in remuneration settings, e.g. across the EU, are frequently criticized from a theoretical point of view. However, in this paper we provide a systematic critique of the technology neutrality concept as a foundation for designing policy support schemes in the RES-E technology field. Specifically, the main objective of the paper is to scrutinize the arguments for technology-neutrality, and discuss three conceptual arguments for why technology-specific support schemes could in fact help minimize the societal costs of reaching future RES-E targets. We also briefly address different political economy concerns, which could constrain the choice of cost-effective policy support schemes, and that have to be taken into account for economic policy advice. For empirical illustration of the key arguments we refer to the case of German RES-E policy-making. The central conclusion from this paper is that technology-specific RES-E support schemes may generate significant economic benefits, particularly if technology markets work imperfectly and in second-best policy settings with additional non-internalized market failures. - Highlights: • Three theoretical cost-effectiveness reasons for technology-specific RES-E support. • German case study to show relevance of theoretical arguments for policy-making. • Political economy constraints to technology-neutral support are demonstrated. • Technology-specific RES-E support may generate significant economic benefits.

    A tight mask seal is frequently difficult to obtain and maintain during single-rescuer bag-valve-mask (BVM) ventilation. The ResMed mask (Bella Vista, NSW, Australia) is a continuous-positive-airway-pressure mask (CM) designed for noninvasive ventilation. In this study, we compared the ventilation performances of a standard mask (SM) and a ResMed CM using a simulation manikin in an out-of-hospital single-rescuer BVM ventilation scenario. Thirty emergency medical technicians (EMTs) performed two 2-minute attempts to ventilate a simulation manikin using BVM ventilation, alternatively, with the SM or the ResMed CM in a randomized order. Ventilation parameters including tidal volume and peak airway pressure were measured using computer analysis software connected to the simulation manikin. Successful volume delivery was defined as delivery of 440-540 mL of tidal volume in accord with present cardiopulmonary resuscitation guidelines. BVM ventilation using the ResMed CM produced higher mean (± standard deviation) tidal volumes (452 ± 50 mL vs. 394 ± 113 mL, p = 0.014) and had a higher proportion of successful volume deliveries (65.3% vs. 26.7%, p < 0.001) than that using the SM. Peak airway pressure was higher in BVM ventilation using the ResMed CM (p = 0.035). Stomach insufflation did not occur during either method. Twenty-nine of the participants (96.7%) preferred BVM ventilation using the ResMed CM. BVM ventilations using ResMed CM resulted in a significantly higher proportion of successful volume deliveries meeting the currently recommended range of tidal volume. Clinical studies are needed to determine the value of the ResMed CM for BVM ventilation.

A caracterização dos resíduos foi determinada utilizando-se a microscopia eletrônica de varredura e espectroscopia na região do infravermelho a qual indicou a presença de grupos carboxílicos, hidroxila e carbonila. O tempo necessário para que o sistema atingisse o equilíbrio para ambos os resíduos foi de 240 min, seguindo uma cinética descrita pelo modelo de pseudo-segunda ordem. A capacidade máxima de adsorção foi de 102,8 mg g-1 para o resíduo da palha de milho, seguindo o modelo de isoterma de Langmuir e 50,9 mg g-1 para o resíduo de palmito pupunha, sendo que o modelo que melhor se ajusta foi Freundlich. Desta forma, esses resíduos são promissores para a adsorção do corante azul de metileno em efluentes.

  18. Revisiting long-run relations in power markets with high RES penetration

    2016-01-01

    Electricity generation from renewable energy resources (RES) has become increasingly significant to reach EU and emissions reduction targets. At the same time, one of the main EU policy goals has been the creation of a common internal energy market for Europe. In this paper, we focus on these two issues previously studied separately, considering their possible interactions. We first analyze the long-run relationship between day-ahead electricity prices and fuel prices (natural gas and coal) looking at two samples of years characterized by low and high RES penetration, then we explore the integration of EU markets. We show that the electricity–fuel nexus found over 2006–2008 changed dramatically over 2010–2014 for the majority of countries considered. In particular, the long-run dependence of electricity from gas and coal prices is much lower in recent years. Furthermore, our results confirm that the considered EU countries are becoming less integrated as RES-E increases. Our findings suggest that nationally implemented policies to support renewables are successful in increasing RES penetration, but they have lessened the linkage among EU markets, then making integration more difficult to obtain. - Highlights: •RES lower the intra-daily electricity dependence from coal and natural gas. •RES affect the EU wholesale electricity market integration, studied at hourly level. •Overlapping national and supranational policies tackle the achievement of EU targets. •Strong policy coordination is required to avoid that the “greens” promote the “dirtiest”.

    The purpose of this study was to determine the mastery of Content Representation (CoRes) teachers related to the integration of technology and pedagogy in teaching Biology (TPACK). This research uses a descriptive method. The data were taken using instruments CoRes as the primary data and semi-structured interviews as supporting data. The subjects were biology teacher in class X MIA from four schools in Bandung. Teachers raised CoRes was analyzed using a scoring rubric CoRes with coding 1-3 then categorized into a group of upper, middle, or lower. The results showed that the two teachers in the lower category. This results means that the control of teachers in defining the essential concept in the CoRes has not been detailed and specific. Meanwhile, two other teachers were in the middle category. This means that the ability of teachers to determine the essential concepts in the CoRes are still inadequate so that still needs to be improved.

    In this paper, we present the formation of large-size rhenium disulfide (ReS2) films via the sulfurization of Re films deposited on sapphire substrates. The effects of sulfurization temperature and pressure on the crystal quality were investigated. A [001]-oriented single crystal of ReS2 films with 6 × 10 mm2 area was realized. By sulfurizing Re films at 1100 °C, ReS2 films with well-defined sharp interfaces to c-plane sapphire substrates could be formed. Below and above the sulfurization temperature of 1100 °C, incomplete sulfurization and film degradation were observed. The twofold symmetry of the monocrystalline in-plane structure composed of Re-Re bonds along with Re-S bonds pointed to a distorted 1T structure, indicating that this structure is the most stable atomic arrangement for ReS2. For a S/Re compositional ratio equal to or slightly lower than 2.0, characteristic Raman vibrational modes with the narrowest line widths were observed. The typical absorption peak of ReS2 can be detected at 1.5 eV.

    2D transition metal dichalcogenides materials are explored as potential surface-enhanced Raman spectroscopy substrates. Herein, a systematic study of the Raman enhancement mechanism on distorted 1T (1T') rhenium disulfide (ReS 2 ) nanosheets is demonstrated. Combined Raman and photoluminescence studies with the introduction of an Al 2 O 3 dielectric layer unambiguously reveal that Raman enhancement on ReS 2 materials is from a charge transfer process rather than from an energy transfer process, and Raman enhancement is inversely proportional while the photoluminescence quenching effect is proportional to the layer number (thickness) of ReS 2 nanosheets. On monolayer ReS 2 film, a strong resonance-enhanced Raman scattering effect dependent on the laser excitation energy is detected, and a detection limit as low as 10 -9 m can be reached from the studied dye molecules such as rhodamine 6G and methylene blue. Such a high enhancement factor achieved through enhanced charge interaction between target molecule and substrate suggests that with careful consideration of the layer-number-dependent feature and excitation-energy-related resonance effect, ReS 2 is a promising Raman enhancement platform for sensing applications. © 2018 WILEY-VCH Verlag GmbH & Co.

    In this paper, we perform a systematic and rigorous study to evaluate the Ohmic nature of the top-contact formed by the monolayer ReS 2 (mReS 2 ) and metals (gold, silver, platinum, nickel, titanium, and scandium) by means of first-principles density functional theory calculations. We investigate the potential barrier, charge transfer and atomic orbital overlap at the mReS 2 -metal interface in consideration of van der Waals forces to understand how efficiently carriers could be injected from the metal contact to the mReS 2 channel. ReS 2 is physisorbed on Au and Ag, which leads to little perturbation of its electronic structures and forms a larger Schottky contact and a higher tunnel barrier at the interface. ReS 2 is chemisorbed on Ti and Sc, where the bonding strongly perturbs the electronic structures and is found to be purely Ohmic. The bonding of ReS 2 on Pt and Ni lies between these two extreme cases, demonstrating an intermediate behavior. These findings not only provide an insight into the mReS 2 -metal interfaces but may also prove to be instrumental in the future design of ReS 2 -based devices with good performance.

    In this study, a direct sulfidation reaction of ammonium perrhenate (NH4ReO4) leading to a synthesis of rhenium disulfide (ReS2) is demonstrated. These findings reveal the first example of a simplistic bottom-up approach to the chemical synthesis of crystalline ReS2. The reaction presented here takes place at room temperature, in an ambient and solvent-free environment and without the necessity of a catalyst. The atomic composition and structure of the as-synthesized product were characterized using several analysis techniques including energy dispersive x-ray spectroscopy, x-ray photoelectron spectroscopy, x-ray diffraction, transmission electron microscopy, Raman spectroscopy, thermogravimetric analysis and differential scanning calorimetry. The results indicated the formation of a lower symmetry (1Tʹ) ReS2 with a low degree of layer stacking.

    Highlights: • The ReS_2/rGO composites have been synthesized by a facile one-pot method. • The ReS_2/rGO composites exhibit hierarchical architecture. • The ReS_2/rGO composites deliver better electrochemical performances than ReS_2. • The enhanced performance is due to porous and conductive structure of ReS_2/rGO. - Abstract: Rhenium disulfide (ReS_2), a two-dimensional (2D) semiconductor, has attracted more and more attention due to its unique anisotropic electronic, optical, mechanical properties. However, the facile synthesis and electrochemical property of ReS_2 and its composite are still necessary to be researched. In this study, for the first time, the ReS_2/reduced graphene oxide (rGO) composites have been synthesized through a facile and one-pot hydrothermal method. The ReS_2/rGO composites exhibit a hierarchical, interconnected, and porous architecture constructed by nanosheets. As anode for lithium-ion batteries, the as-synthesized ReS_2/rGO composites deliver a large initial capacity of 918 mAh g"−"1 at 0.2 C. In addition, the ReS_2/rGO composites exhibit much better electrochemical cycling stability and rate capability than that of bare ReS_2. The significant enhancement in electrochemical property can be attributed to its unique architecture constructed by nanosheets and porous structure, which can allow for easy electrolyte infiltration, efficient electron transfer, and ionic diffusion. Furthermore, the graphene with high electronic conductivity can provide good conductive passageways. The facile synthesis approach can be extended to prepare other 2D transition metal dichalcogenides semiconductors for energy storage and catalytic application.

  8. Revisiting support policies for RES-E adulthood: Towards market compatible schemes

    International Nuclear Information System (INIS)

    2017-01-01

    The past two decades of growth in renewable energy sources of electricity (RES-E) have been largely driven by out-of-market support policies. These schemes were designed to drive deployment on the basis of specific subsidies sustained in time to allow for the larger costs as well as to limit investor risk. While these policies have proven to be effective, the way they have been designed to date has led to costly market distortions that are becoming more difficult to ignore as penetrations reach unpreceded levels. In the context of this growing concern, we provide a critical analysis of the design elements of RES-E support schemes, focusing on how they affect this trade-off between promoting and efficiently integrating RES-E. The emphasis is on the structure of the incentive payment, which in the end turns to be the cornerstone for an efficient integration. We conclude that, while needed, a well-designed and further developed capacity-based support mechanism complemented with ex-post compensations defined for reference benchmark plants, such as the mechanism currently implemented in Spain, is an alternative with good properties if the major goal is truly market integration. The approach is robust to future developments in technology cost, performance and market penetration of RES-E. - Highlights: • Market distortions due to RES support mechanisms are becoming difficult to ignore. • This paper provides a critical analysis of the design elements of RES support schemes. • The emphasis is on the structure of the incentive, key for an efficient integration. • We argue in favor of a further developed capacity-based support mechanism. • The incentive should be combined with the design of a set of reference plants.

    In Italy, the cost of support for renewable electricity (RES-E) is largely recovered through the “A3 surcharge”, which weighs heavily on electricity bills. Using household survey data, we show the A3 surcharge is markedly regressive. Carbon taxation in the non-ETS sector is envisaged as a means to reduce CO_2 emissions cost-effectively and generate revenue to lower the A3 surcharge. A non-ETS carbon tax would be less regressive than the A3 surcharge and its cost would be more evenly distributed across households. We calculate the revenue of a €20/tCO_2 non-ETS carbon tax would have allowed a cut in the A3 surcharge of about 68% in 2011, and 39% in 2012. The impact of the carbon tax plus the reduced A3 surcharge would have been less regressive, but the cost higher for most households. The restrictions imposed in the simulations mean the results are only appropriate to render first-round effects of the reform. Policy relevance: In the vast majority of the EU Member States, the cost of RES-E support is largely paid by electricity consumers, most often through specific surcharges. Rising electricity prices are a common concern given the implications for competitiveness and equity. The Member States facing this issue could conveniently address it through environmental tax reforms consistent with the Climate and Energy Package. Replacing RES-E surcharges with carbon taxes in the non-ETS sector would permit cost-effective reduction of CO_2 emissions while allocating the cost of RES-E support more equitably. The difference in regressivity would stem from the different consumption patterns of home fuels (including electricity) and motor fuels across income distribution. A cross-country comparison of energy household budget shares proves the structural nature of this difference between home fuels and motor fuels. Moreover, the notion that electricity consumers should pay for RES-E support is questioned on the grounds that electricity is a basic necessity good and RES

    Full Text Available Um dos maiores problemas ambientais da atualidade é a excessiva geração de resíduos e a sua destinação final ambientalmente adequada. As Instituições de Ensino Superior (IES são importantes fontes geradoras devido à diversidade de atividades de ensino, pesquisa e extensão realizadas no seu âmbito. Os Restaurantes Escola (RE atendem à comunidade acadêmica dos campi universitários, e caracterizam-se por produzir resíduos similares aos domésticos, mas em maior quantidade. Este estudo foi realizado com o objetivo de investigar a composição gravimétrica dos resíduos produzidos em um RE de uma IES localizada no sul do país, bem como conhecer a situação atual do gerenciamento dos resíduos. Os dados foram obtidos através da caracterização dos resíduos do RE durante cinco dias, de entrevista com os gestores responsáveis pelo estabelecimento e da observação direta no local. Averiguou-se a inexistência de um Plano de Gerenciamento dos Resíduos Sólidos no RE, bem como a ausência de práticas efetivas relacionadas ao manejo destes. A segregação dos resíduos é prejudicada devido à falta de lixeiras específicas e a sobrecarga dos funcionários quanto às atividades desempenhadas. Ao longo do período experimental foram caracterizados 547,068 Kg de resíduos, dos quais mais de 80% corresponderam à matéria orgânica. Conclui-se que o montante de resíduo orgânico gerado pode ser destinado à compostagem. Recomenda-se a implantação de uma infraestrutura adequada para o manejo dos resíduos, que pode ser feita através da elaboração e aplicação de um plano de gestão integrada dos resíduos sólidos no RE.Abstract Nowadays, the amount of waste generated and its proper final destination is one of the greatest environmental issues.

  11. Electronic and optoelectronic device applications based on ReS2

    Science.gov (United States)

    Liu, Erfu; Long, Mingsheng; Wang, Yaojia; Pan, Yiming; Ho, Chinghwa; Wang, Baigeng; Miao, Feng

    Rhenium disulfide (ReS2) is a unique semiconducting TMD with distorted 1T structure and weak interlayer coupling. We have previously investigated its in-plane anisotropic property and electronic applications on FET and digital inverters. In this talk, we will present high responsivity phototransistors based on few-layer ReS2. Depending on the back gate voltage, source drain bias and incident optical light intensity, the maximum attainable photoresponsivity can reach as high as 88,600 A W-1, which is one of the highest value among individual two-dimensional materials with similar device structures. Such high photoresponsivity is attributed to the increased light absorption as well as the gain enhancement due to the existence of trap states in the few-layer ReS2 flakes. The existence of trap states is proved by temperature dependent transport measurements. It further enables the detection of weak signals. Our studies underscore ReS2 as a promising material for future electronic and sensitive optoelectronic applications.

  18. Distribution of costs induced by the integration of RES-E power

    International Nuclear Information System (INIS)

    Barth, Ruediger; Weber, Christoph; Swider, Derk J.

    2008-01-01

    This article focuses on the distribution of costs induced by the integration of electricity generation from renewable energy sources (RES-E). The treatment to distribute these costs on different market actors is crucial for its development. For this purpose, individual actors of electricity markets and several cost categories are identified. According to the defined cost structure, possible treatments to distribute the individual cost categories on different relevant actors are described. Finally, an evaluation of the cost distribution treatments based on an economic analysis is given. Economic efficiency recommends that clearly attributable (shallow) grid connection as well as (deep) grid costs are charged to the corresponding RES-E producer and that the RES-E producers are also charged the regulating power costs. However, deep grid integration costs should be updated to reflect evolving scarcities. Also regulating power costs should reflect actual scarcity and thus be symmetric and based on real-time prices, taking into account the overall system imbalance. Moreover, the time span between the closure of the spot market and actual delivery should be chosen as short as possible to enable accurate RES-E production forecasts

  19. Res-Parity: Parity Violation in Inelastic scattering at Low Q2

    2006-01-01

    Parity violating electron scattering has become a well established tool which has been used, for example, to probe the Standard Model and the strange-quark contribution to the nucleon. While much of this work has focused on elastic scattering, the RES-Parity experiment, which has been proposed to take place at Jefferson Laboratory, would focus on inelastic scattering in the low-Q 2 , low-W domain. RES-Parity would search for evidence of quark-hadron duality and resonance structure with parity violation in the resonance region. In terms of parity violation, this region is essentially unexplored, but the interpretation of other high-precision electron scattering experiments will rely on a reasonable understanding of scattering at lower energy and low-W through the effects of radiative corrections. RES-Parity would also study nuclear effects with the weak current. Because of the intrinsic broad band energy spectrum of neutrino beams, neutrino experiments are necessarily dependent on an untested, implicit assumption that these effects are identical to electromagnetic nuclear effects. RES-Parity is a relatively straight forward experiment. With a large expected asymmetry (∼ 0.5 x 10 -4 ) these studies may be completed with in a relatively brief period

    Given the mentioned circumstances, conventional energy planning in the Canary Islands is a very complex task. The Regional Energy Plan PECAN (2007-2015) tries to correct the existing critical situation setting, among others, the ambitious goal of >25% electricity from RES (mostly wind) for 2015. In parallel to this conventional energy planning, outstanding initiatives in the distributed generation field are underway. ITC vision is that the Canarian Archipelago, given its particular characteristics (insular systems of different sizes, abundant RES potential -different sources-, important natural and biodiversity heritage, etc.), are a laboratory for testing and demonstrating new energy technologies in real conditions, as well as their commercial implementation. These new technologies include energy storage (particularly for excess RES that cannot be absorbed by the grids), development of 100% energy self- sufficiency models (with exclusive use of RES) and micro-/minigrids with high RES penetration and RES forecasting, including advanced ICTs and sustainable mobility concepts (e.g. V2G technologies). Given the high conventional generation costs and the relatively low RES costs (wind electricity production cost is less than 0.03 Euro/kWh), the Canary Islands could in the short term achieve grid parity, and in this sense pioneer the change to a RES based energy system. Models tested on the islands could be exported or extrapolated to our islands, regions of developing countries and even other regions in continental Europe. (orig.)

    Full Text Available Cet article se propose d’étudier une œuvre publiée en 1991 par la romancière anglaise Pat Barker : Regeneration. Ce roman, qui a pour toile de fond la Grande Guerre, ne dépeint ni combats ni scènes de la vie des tranchées. Barker préfère représenter toute la dimension agonistique de ce conflit mondial à travers la question de la prise en charge des traumatismes de guerre des soldats par l’institution psychiatrique. Ces traumatismes, ayant diverses manifestations psychosomatiques, témoignent d’une forte tension entre une profonde aversion de l’individu pour l’extrême violence des affrontements et un appel à se conformer à une certaine culture de guerre collective fondée sur un idéal fort de virilité martiale et patriotique. Face à ces traumatismes, ainsi que Pat Barker le met en lumière, la psychiatrie de guerre se révèle souvent fort ambiguë. En effet, l’institution psychiatrique œuvre en continuité avec l’institution militaire, désirant imposer un contrôle sur les âmes autant que sur les corps. Regeneration nous invite donc à lire combien les maux/mots de la Grande Guerre ont eu grand peine à se faire entendre.This article deals with a novel, entitled Regeneration, published in 1991 by the English female author Pat Barker. This novel, although set against the backdrop of World War One, depicts neither battles nor scenes of everyday life in the trenches. Instead, the agonistic dimension of this world conflict is tackled by Pat Barker through the prism of the way the psychiatric institution dealt with war traumas endured by soldiers, traumas of the body and of the mind. These traumas, causing a variety of psychosomatic symptoms, reveal a powerful tension between a deep individual aversion to the extreme violence of combat and an appeal to conform to some collective culture of war rooted in a strong ideal of soldierly and patriotic manliness. Wartime psychiatry, as Barker highlights, often turns out to

    Fertile soils are a fundamental resource for the production of biomass and provision of food and energy. A growing world population and latest climate targets lead to an increasing demand for bio-based products which require preserving and - ideally - improving the long-term productivity of soils as a bio-economic resource. At the same time, other soil functions and ecosystem services need to be maintained: filter for clean water, carbon sequestration, provision and recycling of nutrients, and habitat for biological activity. All these soil functions result from the interaction of a multitude of physical, chemical and biological processes which are insufficiently understood. In addition, we lack understanding about the interplay between the socio-economic system and the soil system and how soil functions benefit human wellbeing, including SDGs. However, a solid and integrated assessment of soil quality requires the consideration of the ensemble of soil functions and its relation to soil management. To make soil management sustainable, we need to establish a scientific knowledge base of complex soil system processes that allows for developing models and tools to quantitatively predict the impact of a multitude of management measures on soil functions. This will finally allow for the provision of options for a site-specific, sustainable soil management. To face this challenge, the German Federal Ministry of Education and Research (BMBF) recently launched the funding program "Soil as a Sustainable Resource for the Bioeconomy - BonaRes". In a joint effort, ten collaborative projects and the coordinating BonaRes Centre are engaged to close existing knowledge gaps for a profound and systemic assessment and understanding of soil functions and their sensitivity to soil management. In BonaRes, the complete process chain of sustainable soil use in the context of a sustainable bio-economy is being addressed: from understanding of soil processes using state-of the art and

    The ResStock analysis tool is helping states, municipalities, utilities, and manufacturers identify which home upgrades save the most energy and money. Across the country there's a vast diversity in the age, size, construction practices, installed equipment, appliances, and resident behavior of the housing stock, not to mention the range of climates. These variations have hindered the accuracy of predicting savings for existing homes. Researchers at the National Renewable Energy Laboratory (NREL) developed ResStock. It's a versatile tool that takes a new approach to large-scale residential energy analysis by combining: large public and private data sources, statistical sampling, detailed subhourly building simulations, high-performance computing. This combination achieves unprecedented granularity and most importantly - accuracy - in modeling the diversity of the single-family housing stock.

  11. The future has come: the 100% RES driven power system is reality

    International Nuclear Information System (INIS)

    Orths, Antje; Borre Eriksen, Peter

    2016-01-01

    The Danish political energy and climate targets fixed in the RES (Renewable Energy Sources) directive require Denmark to reach a 30 % RES share of its total energy consumption in 2020. Besides, Danish national targets aim at wind power production to correspond to 50 % of domestic gross electricity consumption (status in 2015: 42 %). For 2050, the political target is to be free of fossil fuels in the whole energy sector - i.e. including transportation. The major part of variable RES in Denmark is wind energy, the remaining power consumption mainly based on biomass, gas and coal fired central power stations and local CHP plants. Some key figures: at the end of 2015, 5,076 MW wind power capacity and 783 MW of solar power capacity were installed in Denmark, with Danish peak load at ∼6.400 MW and the total electricity consumption at 33.6 TWh. Wind power is split into 3,805 MW onshore and 1.272 MW offshore installations. In 2015, wind power produced 14.1 TWh electricity (9.3 TWh onshore, 4.8 TWh offshore), which made a ∼42 % share of the Danish electricity consumption, while solar power produced 0.6 TWh. The high RES level is already today challenging the system e.g. concerning the need for flexibility on the one hand, or by pushing power plants delivering important system services out of the market on the other hand. To fulfill the political ambitions, new arrangements concerning the technical and market design incentivizing flexibility or ancillary services, such as frequency control and voltage control, are needed and currently under development. This article gives examples and illustrates the urgency by showing a real dispatch in a windy week. (authors)

    2004-01-01

    This report documents state-of-the-art methods, tools, and data for the conduct of a fire Probabilistic Risk Assessment (PRA) for a commercial nuclear power plant (NPP) application. The methods have been developed under the Fire Risk Re-quantification Study. This study was conducted as a joint activity between EPRI and the U. S. NRC Office of Nuclear Regulatory Research (RES) under the terms of an EPRI/RES Memorandum of Understanding (RS.1) and an accompanying Fire Research Addendum (RS.2). Industry participants supported demonstration analyses and provided peer review of this methodology. The documented methods are intended to support future applications of Fire PRA, including risk-informed regulatory applications. The documented method reflects state-of-the-art fire risk analysis approaches. The primary objective of the Fire Risk Study was to consolidate recent research and development activities into a single state-of-the-art fire PRA analysis methodology. Methodological issues raised in past fire risk analyses, including the Individual Plant Examination of External Events (IPEEE) fire analyses, have been addressed to the extent allowed by the current state-of-the-art and the overall project scope. Methodological debates were resolved through a consensus process between experts representing both EPRI and RES. The consensus process included a provision whereby each major party (EPRI and RES) could maintain differing technical positions if consensus could not be reached. No cases were encountered where this provision was invoked. While the primary objective of the project was to consolidate existing state-of-the-art methods, in many areas, the newly documented methods represent a significant advancement over previously documented methods. In several areas, this project has, in fact, developed new methods and approaches. Such advances typically relate to areas of past methodological debate.

    2014-01-01

    Scarcity or abundance of energy resources usually depends on physical and geographical conditions in the region. However, the energy flow in the region also depends on the efficient use of energy resources, the consumption rate of energy and the possibility to use local renewable and non-renewable energy resources. Production, distribution and the use of energy resources in the region are the challenges for central and local government, business and social service, customers and other stakeholders. Development of regional energy economy should be optimized according to the available energy flow in the region using a network system analysis method, which provides solutions for developing sustainable energy economy models. The network system analysis method enables to optimize the use of local and renewable resources at the regional level and reveals available local energy resources. An efficient use of available regional resources and the use of renewable energy sources (RES) should be the main goals for the development of regional energy system. RES can compete with traditional fossil fuel with the condition that all hidden aspects are revealed.

    TREX1 constitutes the major 3′→5′ DNA exonuclease activity measured in mammalian cells. Recently, biallelic mutations in TREX1 have been shown to cause Aicardi-Goutières syndrome at the AGS1 locus. Interestingly, Aicardi-Goutières syndrome shows overlap with systemic lupus erythematosus at both clinical and pathological levels. Here, we report a heterozygous TREX1 mutation causing familial chilblain lupus. Additionally, we describe a de novo heterozygous mutation, affecting a critical catalytic residue in TREX1, that results in typical Aicardi-Goutières syndrome. PMID:17357087

    Highlights: • Guidelines for power utilities to reach specific decarbonisation targets offered. • Optimization model of RES share to be introduced into power system is proposed. • Single criteria analysis and multicriteria sustainability assessment are applied. • The optimization method has been demonstrated on a real power system. • In the considered case, HIGH RES scenario showed to be the preferable one. - Abstract: This paper provides guidelines and principles for power utilities to reach specific energy and decarbonisation targets. Method of power generation portfolio optimization, as function of sustainability and decarbonisation, along with appropriate criteria, has been proposed. Application of this optimization method has been demonstrated on a real power system – power utility JP Elektroprivreda BiH d.d. – Sarajevo (EPBiH), a typical example of South East European power system. The software tool WASP IV has been employed in the analysis, in order to define the dynamics and an optimized expansion of generation portfolio of the power system under consideration for the next period. The mid-term generation portfolio development plan for the EPBiH power system until year 2030 has been made during this research, taking into account the shutdown dynamics of existing power units and commissioning new ones, in order to provide safe supply of electric and heat energy for local consumers. Three basic scenario of renewable energy sources (RES) expansion have been analysed to reach specific RES and decarbonisation targets set for 2030, including RES share increase from the current level of 18% up to 35% (LOW RES), 45% (MID RES) and 55% (HIGH RES). Effects to the sustainability are considered through environmental, economic and social indicators. Multicriteria sustainability assessment gave an advantage to the HIGH RES, under assumption of equal weighting factors of economic and environment groups of indicators. Also, single criteria analysis has been

    Substitutional doping of transition metal dichalcogenide two-dimensional materials has proven to be effective in tuning their intrinsic properties, such as band gap, transport characteristics, and magnetism. In this study, we realized substitutional doping of monolayer rhenium disulfide (ReS 2 ) with Mo via chemical vapor deposition. Scanning transmission electron microscopy demonstrated that Mo atoms are successfully doped into ReS 2 by substitutionally replacing Re atoms in the lattice. Electrical measurements revealed the degenerate p-type semiconductor behavior of Mo-doped ReS 2 field effect transistors, in agreement with density functional theory calculations. The p-n diode device based on a doped ReS 2 and ReS 2 homojunction exhibited gate-tunable current rectification behaviors, and the maximum rectification ratio could reach up to 150 at V d = -2/+2 V. The successful synthesis of p-type ReS 2 in this study could largely promote its application in novel electronic and optoelectronic devices.

J Strength Cond Res 32(1): 323-329, 2017-This study examined the possibility of using movement velocity and the perceived exertion as indicators of relative load in the bench press (BP) exercise. A total of 308 young, healthy, resistance trained athletes (242 men and 66 women) performed a progressive strength test up to the one repetition maximum for the individual determination of the full load-velocity and load-exertion relationships. Longitudinal regression models were used to predict the relative load from the average velocity (AV) and the OMNI-Resistance Exercise Scales (OMNI-RES 0-10 scale), considering sets as the time-related variable. Load associated with the AV and the OMNI-RES 0-10 scale value expressed after performing a set of 1-3 repetitions were used to construct 2 adjusted predictive equations: Relative load = 107.75 - 62.97 × average velocity; and Relative load = 29.03 + 7.26 × OMNI-RES 0-10 scale value. The 2 models were capable of estimating the relative load with an accuracy of 84 and 93%, respectively. These findings confirm the ability of the 2 calculated regression models, using load-velocity and load-exertion from the OMNI-RES 0-10 scale, to accurately predict strength performance in BP.

    Anisotropic two-dimensional (2D) van der Waals (vdW) layered materials, with both scientific interest and application potential, offer one more dimension than isotropic 2D materials to tune their physical properties. Various physical properties of 2D multi-layer materials are modulated by varying their stacking orders owing to significant interlayer vdW coupling. Multilayer rhenium disulfide (ReS2), a representative anisotropic 2D material, was expected to be randomly stacked and lack interlayer coupling. Here, we demonstrate two stable stacking orders, namely isotropic-like (IS) and anisotropic-like (AI) N layer (NL, N > 1) ReS2 are revealed by ultralow- and high-frequency Raman spectroscopy, photoluminescence and first-principles density functional theory calculation. Two interlayer shear modes are observed in AI-NL-ReS2 while only one shear mode appears in IS-NL-ReS2, suggesting anisotropic- and isotropic-like stacking orders in IS- and AI-NL-ReS2, respectively. This explicit difference in the observed frequencies identifies an unexpected strong interlayer coupling in IS- and AI-NL-ReS2. Quantitatively, the force constants of them are found to be around 55-90% of those of multilayer MoS2. The revealed strong interlayer coupling and polytypism in multi-layer ReS2 may stimulate future studies on engineering physical properties of other anisotropic 2D materials by stacking orders.Anisotropic two-dimensional (2D) van der Waals (vdW) layered materials, with both scientific interest and application potential, offer one more dimension than isotropic 2D materials to tune their physical properties.

    Lawrence Livermore National Laboratory developed a space-qualified High Resolution (HiRes) imaging LIDAR (Light Detection And Ranging) system for use on the DoD Clementine mission. The Clementine mission provided more than 1.7 million images of the moon, earth, and stars, including the first ever complete systematic surface mapping of the moon from the ultra-violet to near-infrared spectral regions. This article describes the Clementine HiRes/LIDAR system, discusses design goals and preliminary estimates of on-orbit performance, and summarizes lessons learned in building and using the sensor. The LIDAR receiver system consists of a High Resolution (HiRes) imaging channel which incorporates an intensified multi-spectral visible camera combined with a Laser ranging channel which uses an avalanche photo-diode for laser pulse detection and timing. The receiver was bore sighted to a light-weight McDonnell-Douglas diode-pumped ND:YAG laser transmitter that emmitted 1.06 {micro}m wavelength pulses of 200 mJ/pulse and 10 ns pulse-width, The LIDAR receiver uses a common F/9.5 Cassegrain telescope assembly. The optical path of the telescope is split using a color-separating beamsplitter. The imaging channel incorporates a filter wheel assembly which spectrally selects the light which is imaged onto a custom 12 mm gated image intensifier fiber-optically-coupled into a 384 x 276 pixel frame transfer CCD FPA. The image intensifier was spectrally sensitive over the 0.4 to 0.8 {micro}m wavelength region. The six-position filter wheel contained 4 narrow spectral filters, one broadband and one blocking filter. At periselene (400 km) the HiRes/LIDAR imaged a 2.8 km swath width at 20-meter resolution. The LIDAR function detected differential signal return with a 40-meter range accuracy, with a maximum range capability of 640 km, limited by the bit counter in the range return counting clock.

    Transition metal dichalcogenides are predicted to outperform traditional semiconductors in ballistic devices with nanoscale channel lengths. So far, experimental studies on charge transport in transition metal dichalcogenides are limited to the diffusive regime. Here we show, using ReS2 as an example, all-optical injection, detection, and coherent control of ballistic currents. By utilizing quantum interference between one-photon and two-photon interband transition pathways, ballistic currents are injected in ReS2 thin film samples by a pair of femtosecond laser pulses. We find that the current decays on an ultrafast time scale, resulting in an electron transport of only a fraction of one nanometer. Following the relaxation of the initially injected momentum, backward motion of the electrons for about 1 ps is observed, driven by the Coulomb force from the oppositely moved holes. We also show that the injected current can be controlled by the phase of the laser pulses. These results demonstrate a new platform to study ballistic transport of nonequilibrium carriers in transition metal dichalcogenides.

    The Raman tensor of a crystal is the derivative of its polarizability tensor and is dependent on the symmetries of the crystal and the Raman-active vibrational mode. The intensity of a particular mode is determined by the Raman selection rule, which involves the Raman tensor and the polarization configurations. For anisotropic two-dimensional (2D) layered crystals, polarized Raman scattering has been used to reveal the crystalline orientations. However, due to its complicated Raman tensors and optical birefringence, the polarized Raman scattering of triclinic 2D crystals has not been well studied yet. Herein, we report the anomalous polarized Raman scattering of 2D layered triclinic rhenium disulfide (ReS 2 ) and show a large circular intensity differential (CID) of Raman scattering in ReS 2 of different thicknesses. The origin of CID and the anomalous behavior in polarized Raman scattering were attributed to the appearance of nonzero off-diagonal Raman tensor elements and the phase factor owing to optical birefringence. This can provide a method to identify the vertical orientation of triclinic layered materials. These findings may help to further understand the Raman scattering process in 2D materials of low symmetry and may indicate important applications in chiral recognition by using 2D materials.

    Full Text Available The author discusses the effects of the res judicata rule as regards jurisdictional decisions of the International Court of Justice. He finds that there exists a special position of a judgment on preliminary objection in respect to both aspects of the res judicata rule - its binding force and finality. A perception of distinct relativity of a jurisdictional decision of the Court, expressing its interlocatory character pervades, in his opinion, the body of law regulating the Court's activity. Preliminary objections as such do not exhaust objections to the jurisdiction of the Court, as evidenced by non-preliminary objections to the jurisdiction of the Court giving rise to the application of the principle compétence de la compétence understood in the narrow sense. With regard to the binding force of a judgment on preliminary objections, it does not create legal obligations stricto sensu. The author finds that the relative character of jurisdictional decisions of the Court as compared with a judgment on the merits is justified on a number of grounds.

    We demonstrated the fabrication of large-area ReS 2 transistors and logic gates composed of a chemical vapor deposition (CVD)-grown multilayer ReS 2 semiconductor channel and graphene electrodes. Single-layer graphene was used as the source/drain and coplanar gate electrodes. An ion gel with an ultrahigh capacitance effectively gated the ReS 2 channel at a low voltage, below 2 V, through a coplanar gate. The contact resistance of the ion gel-gated ReS 2 transistors with graphene electrodes decreased dramatically compared with the SiO 2 -devices prepared with Cr electrodes. The resulting transistors exhibited good device performances, including a maximum electron mobility of 0.9 cm 2 /(V s) and an on/off current ratio exceeding 10 4 . NMOS logic devices, such as NOT, NAND, and NOR gates, were assembled using the resulting transistors as a proof of concept demonstration of the applicability of the devices to complex logic circuits. The large-area synthesis of ReS 2 semiconductors and graphene electrodes and their applications in logic devices open up new opportunities for realizing future flexible electronics based on 2D nanomaterials.

    Full Text Available RESUMO A gestão de resíduos dos serviços de saúde (RSS constitui um grande desafio para o poder público, pois, apesar do avanço nos aspectos legislativos, ainda há grandes deficiências, especialmente relacionadas aos resíduos de medicamentos descartados inadequadamente. Este estudo teve como objetivo caracterizar o processo de descarte de drogas e resíduos dos serviços de saúde humana e veterinária em uma cidade de médio porte da Região Serrana de Santa Catarina. Foram realizadas visitas às unidades participantes, selecionadas por critérios de conveniência, contemplando unidades de saúde municipais, pet shops , clínicas veterinárias, hospital de atendimento humano, hospital de atendimento veterinário e empresas coletoras, totalizando 15 unidades participantes. A coleta de dados ocorreu de março a maio de 2014, com aplicação de questionários e roteiro de observação de campo. Os resultados evidenciaram deficiências no gerenciamento dos resíduos de medicamentos, assim como dos demais resíduos, nas etapas de segregação e armazenamento em instituições de atendimento humano e veterinário, com poucas exceções. As maiores dificuldades foram observadas nos estabelecimentos de atendimento veterinário, especialmente quanto à segregação e ao armazenamento dos resíduos contaminados, à falta de cuidado com material perfurocortante e às normas de biossegurança. A inexistência do Plano de Gerenciamento de Resíduos de Serviços de Saúde nas unidades de saúde e no hospital veterinário, assim como a falta de capacitações aos profissionais, a dissimilaridade no descarte de medicamentos entre os estabelecimentos e a falta de fiscalização por parte dos órgãos competentes foram os principais responsáveis pelo atual cenário de descarte inadequado dos resíduos na região.

    Mitochondria are sub-cellular organelles that have a central role in energy production and in other metabolic pathways of all eukaryotic respiring cells. In the last few years, with more and more genomes being sequenced, a huge amount of data has been generated providing an unprecedented opportunity to use the comparative analysis approach in studies of evolution and functional genomics with the aim of shedding light on molecular mechanisms regulating mitochondrial biogenesis and metabolism. In this context, the problem of the optimal extraction of representative datasets of genomic and proteomic data assumes a crucial importance. Specialised resources for nuclear-encoded mitochondria-related proteins already exist; however, no mitochondrial database is currently available with the same features of MitoRes, which is an update of the MitoNuc database extensively modified in its structure, data sources and graphical interface. It contains data on nuclear-encoded mitochondria-related products for any metazoan species for which this type of data is available and also provides comprehensive sequence datasets (gene, transcript and protein) as well as useful tools for their extraction and export. MitoRes http://www2.ba.itb.cnr.it/MitoRes/ consolidates information from publicly external sources and automatically annotates them into a relational database. Additionally, it also clusters proteins on the basis of their sequence similarity and interconnects them with genomic data. The search engine and sequence management tools allow the query/retrieval of the database content and the extraction and export of sequences (gene, transcript, protein) and related sub-sequences (intron, exon, UTR, CDS, signal peptide and gene flanking regions) ready to be used for in silico analysis. The tool we describe here has been developed to support lab scientists and bioinformaticians alike in the characterization of molecular features and evolution of mitochondrial targeting sequences.

    Enhanced in 2014, the energy and climate goals for 2030 of the European Union require the mobilization of everyone, everywhere. In a dynamic set to intensify rural territories, as well as cities, the communities have a major role to play. As the principal trustees of renewable resource deposits, they are the vanguard of the energy transition. Their strengths? Wind and water in abundance (very often), the sun of course, biomass - agricultural, forest, woodland, domestic, food processing - geothermal energy. With the desire to make this renewable capital live, it made some decide to take or regain control of the energy issue, reduce their energy bills and those of their inhabitants. Attracted by the opportunity to revitalize local economies and rural communes (alone or in groups) they are more likely to want to become 100% RES. But how to move from intention to action when faced with the lack of knowledge, or means, or when you feel too small to act? It is to assist you in developing your energy policy that this guide was written. Pragmatic, practical, it brings together the return on experience from partners and communities involved in 100% RES Communities project. For three years, elected representatives from rural areas, some experienced and some less, together with experts from 10 countries in Europe, have sought the best organizational, technical and financial means to reduce consumption and produce renewable energy. If because of the administrative, cultural, economic differences within the Union, all the territories do not enjoy the same facilities, the 100% RES Communities project has defined pragmatic methods, practices and tools which will make your work easier. You will find in this guide the key steps in defining your strategy and building your action plan. This is a feasible action plan to be shared and implemented with the stakeholders. A final note: because it is within networks that we discover new solutions, which can replenish the practices and

    Denatured radioiodinated human serum albumin (DHA) clearance studies at a dose of 1 mg/kg body wt., were carried out in 16 thalassemic children, prior to and 7-10 days following blood transfusion, to investigate changes of the effective RES blood flow which might accompany the posttransfusion spleen size diminution. A statistically significant increase (P<0.001) of the DHA plasma clearance rate was observed 7-10 days following blood transfusion denoting an increase of the blood flow to the effective RES while at the same time the spleen diminished in size. It is suggested that changes in the effective RES blood flow in these patients are directly related to changes in the intrasplenic circulatory capacity. (orig.)

  13. Who benefits from cooperation? A numerical analysis of redistribution effects resulting from cooperation in European RES-E support

    Unteutsch, Michaela

    2014-01-01

    This paper numerically analyzes redistribution effects resulting from cooperation among European countries in achieving the 2020 targets for electricity generation from renewable energy sources (RES-E). The quanti cation of redistribution effects builds on the theoretical analysis by Unteutsch (2014), who shows that cooperation in RES-E support increases overall welfare but is not beneficial for all groups. In this paper, we use a dynamic investment and dispatch optimization model of the European electricity system to investigate which groups potentially benefit from cooperation and which groups would be worse off compared to a situation in which national RES-E targets are reached solely by domestic RES-E production. In the analysis, cooperation in RES-E support is implemented as a European-wide green certificate trading scheme. Main findings of the analysis include that in the European electricity system, effects of the change in the certificate price in most countries would overcompensate for the effects of the change in the wholesale electricity price. Thus, in most countries with comparatively high (low) generation costs for renewable energies, consumer rents increase (decrease) due to cooperation and producers yield lower (higher) profits. In addition, it is found that the magnitude of redistribution effects between the individual groups is quite large: In some countries, the change in consumer rents or producer profits resulting from cooperation is nearly twice as high as the overall welfare effect of cooperation in the whole European electricity system. Moreover, we find that the sign, but not always the magnitude, of redistribution effects is quite robust to different developments of interconnector extensions, the CO 2 price and RES-E investment costs.

    Knowledge of teachers in learning activities in the classroom has a close relationship with how well and how much students learn. Recently, a promising development in teacher education has appeared that centers on the academic construct of pedagogical content knowledge (PCK). This study was an exploratory study into a science teacher education program that seeks to build the foundations on which pre-service teachers can begin to build their pedagogical content knowledge (PCK). The program involved the use of Content Representations (CoRes), which was initially applied as component of a strategy for exploring and gaining insights into the PCK of in-service science teachers. This study involved the researcher and 20 students (third year) in a pre-service teacher education course (School Science I) in science education when the students worked to make content analysis on the digestive system topic. During the course, the students make their own CoRes through a workshop for digestive system topic individually, in pairs and whole class discussion. Data were recorded from students' CoRes, student reflective journals, interviews, and field notes recorded in the researcher's reflective journal. Pre-service teachers' comments from interviews and reflective journals were coded in relation to references about: (1) the effectiveness of variety strategies in building the knowledge bases required to design a CoRes and (2) their awareness and/or development of tentative components of future PCK for a digestive system topic as a result of CoRes construction. Observational data were examined for indications of increasing independence and competency on the part of student teachers when locating appropriate information for designing their CoRes. From this study, it is hoped that the pre-service science teachers are able to build knowledge and then transform it into a form of PCK for digestive system topic for their first classroom planning and teaching to teach digestive system

En la actualidad, la mayoría de las universidades disponen de plataformas virtuales de educación, con un importante peso para el correcto desarrollo de sus estudios y para la optimización del aprendizaje de su alumnado. Por otro lado, los entornos virtuales suponen un importante punto de acceso a la posible matriculación en dichas universidades del alumnado con discapacidad. Este trabajo tiene dos objetivos. El primero de ellos consiste en definir cuáles son las condiciones óptimas de accesibilidad web de las plataformas virtuales de educación y de los sitios web de las universidades para personas que presentan discapacidad visual o discapacidad motórica, de acuerdo a los estándares internacionales. El segundo objetivo del trabajo persigue ofrecer una breve aproximación al grado de accesibilidad de los sitios web de las universidades españolas para el alumnado con esas dos discapacidades. El trabajo sigue un diseño descriptivo basado en dos elementos de análisis. Por un lado, la revisión de estudios de accesibilidad y diversidad funcional y, por otro, el análisis de la accesibilidad web de los sitios web de las 78 universidades españolas. Se concluye que existen dificultades de accesibilidad web y navegación en los entornos virtuales de las universidades españolas, situación que, por lo tanto, redunda en limitaciones en el aprendizaje de los colectivos de estudiantes con limitaciones.

    BonaRes is short for "soil as a sustainable resource for the bioeconomy". It is funded by the German Federal Ministry of Education and Research (BMBF) under the umbrella of the National Research Strategy BioEconomy 2030. BonaRes consists of ten interdisciplinary research project consortia and the 'BonaRes - Centre for Soil Research' (see also Wollschläger et al 2016). It is one task of the BonaRes Data Centre as part of the 'BonaRes - Centre for Soil Research', to collect data and meta-data of agricultural long-term field experiments (LTFE) in Germany. The definition of LTFE in the context of BonaRes is a minimum duration of twenty years and a static design. LTFE are essential research infrastructures for agricultural sciences and soil sciences amongst other disciplines. Some LTFE run since a very long time; the start of the oldest one in Germany was 1878. Therefore, in many cases valuable time series exist. Data sets of LTFE shall be compiled and made publicly available by the BonaRes Data Centre. The public availability together with an easy access will lead to an enhanced usability of the data. This probably makes the LTFE itself more valuable through an improved visibility and may also help to maintain the LTFE. Beyond the data compilation there is the possibility for every data owner to make a data publication, which offers an additional value for the data owner after his first right of use. A first step towards a joint database is a compilation of all existing LTFE in Germany with meta information to each trial. This information is shown in an interactive web map, what is completely new in that context. Besides the exact position of the LTFE the following metadata are shown: name of the LTFE, website (if available), institution, land use category, participation in existing networks, research theme, start (and maybe end) of the trial, and research parameters. Details on the meta information will be presented in the speech. Literature Wollschläger, U; Helming

  3. An RES-Based Model for Risk Assessment and Prediction of Backbreak in Bench Blasting

    Most blasting operations are associated with various forms of energy loss, emerging as environmental side effects of rock blasting, such as flyrock, vibration, airblast, and backbreak. Backbreak is an adverse phenomenon in rock blasting operations, which imposes risk and increases operation expenses because of safety reduction due to the instability of walls, poor fragmentation, and uneven burden in subsequent blasts. In this paper, based on the basic concepts of a rock engineering systems (RES) approach, a new model for the prediction of backbreak and the risk associated with a blast is presented. The newly suggested model involves 16 effective parameters on backbreak due to blasting, while retaining simplicity as well. The data for 30 blasts, carried out at Sungun copper mine, western Iran, were used to predict backbreak and the level of risk corresponding to each blast by the RES-based model. The results obtained were compared with the backbreak measured for each blast, which showed that the level of risk achieved is in consistence with the backbreak measured. The maximum level of risk [vulnerability index (VI) = 60] was associated with blast No. 2, for which the corresponding average backbreak was the highest achieved (9.25 m). Also, for blasts with levels of risk under 40, the minimum average backbreaks (<4 m) were observed. Furthermore, to evaluate the model performance for backbreak prediction, the coefficient of correlation ( R 2) and root mean square error (RMSE) of the model were calculated ( R 2 = 0.8; RMSE = 1.07), indicating the good performance of the model.

  4. The Nordic welfare model providing energy transition? A political geography approach to the EU RES directive

    International Nuclear Information System (INIS)

    Westholm, Erik; Beland Lindahl, Karin

    2012-01-01

    The EU Renewable Energy Strategy (RES) Directive requires that each member state obtain 20% of its energy supply from renewable sources by 2020. If fully implemented, this implies major changes in institutions, infrastructure, land use, and natural resource flows. This study applies a political geography perspective to explore the transition to renewable energy use in the heating and cooling segment of the Swedish energy system, 1980–2010. The Nordic welfare model, which developed mainly after the Second World War, required relatively uniform, standardized local and regional authorities functioning as implementation agents for national politics. Since 1980, the welfare orientation has gradually been complemented by competition politics promoting technological change, innovation, and entrepreneurship. This combination of welfare state organization and competition politics provided the dynamics necessary for energy transition, which occurred in a semi-public sphere of actors at various geographical scales. However, our analysis, suggest that this was partly an unintended policy outcome, since it was based on a welfare model with no significant energy aims. Our case study suggests that state organization plays a significant role, and that the EU RES Directive implementation will be uneven across Europe, reflecting various welfare models with different institutional pre-requisites for energy transition. - Highlights: ► We explore the energy transition in the heating/cooling sector in Sweden 1980–2000. ► The role of the state is studied from a political geography perspective. ► The changing welfare model offered the necessary institutional framework. ► Institutional arrangements stand out as central to explain the relative success. ► The use of renewables in EU member states will continue to vary significantly.

    The retention and splicing (RES) complex is a conserved spliceosome-associated module that was shown to enhance splicing of a subset of transcripts and promote the nuclear retention of unspliced pre-mRNAs in yeast. The heterotrimeric RES complex is organized around the Snu17p protein that binds to both the Bud13p and Pml1p subunits. Snu17p exhibits an RRM domain that resembles a U2AF homology motif (UHM) and Bud13p harbors a Trp residue reminiscent of an UHM-ligand motif (ULM). It has therefore been proposed that the interaction between Snu17p and Bud13p resembles canonical UHM-ULM complexes. Here, we have used biochemical and NMR structural analysis to characterize the structure of the yeast Snu17p-Bud13p complex. Unlike known UHMs that sequester the Trp residue of the ULM ligand in a hydrophobic pocket, Snu17p and Bud13p utilize a large interaction surface formed around the two helices of the Snu17p domain. In total 18 residues of the Bud13p ligand wrap around the Snu17p helical surface in an U-turn-like arrangement. The invariant Trp(232) in Bud13p is located in the center of the turn, and contacts surface residues of Snu17p. The structural data are supported by mutational analysis and indicate that Snu17p provides an extended binding surface with Bud13p that is notably distinct from canonical UHM-ULM interactions. Our data highlight structural diversity in RRM-protein interactions, analogous to the one seen for nucleic acid interactions. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.

    Most medium and small islands of the Aegean Archipelagos face serious infrastructure problems, strongly related with the limited electrical energy available at extremely high cost. On the other hand, the area is characterized by very high wind speeds and abundant solar energy, thus the exploitation of the available renewable energy sources (RES) may significantly contribute to the fulfillment of the local societies energy demand at minimum environmental and macroeconomic cost. However, the stochastic availability of wind energy and the variable availability of solar energy, the daily and seasonal electricity demand fluctuations, as well as the limited local electrical network capacity result in serious restrictions concerning the maximum renewable power penetration. In this context, the present paper investigates the possibility of creating a combined electricity generation facility based on the exploitation of wind or/and solar potential of an area as well as on the utilization of an appropriate energy storage configuration in order to replace the existing thermal power stations with rational investment requirements. For this purpose, the major parameters of the proposed integrated configuration are firstly calculated and its financial viability is accordingly analyzed. One of the main targets of the proposed solution is to maximize the RES exploitation of the area at a minimum electricity generation cost, while special emphasis is given in order to select the most cost-efficient energy storage device available. According to the results obtained the proposed solution is not only financially attractive but also improves the quality of the electricity offered to the local communities, substituting the expensive and heavily polluting existing thermal power stations

    Penetration of renewable energy is strongly slowed by its characteristic intermittency and fluctuating trend and by the inadequacy of electricity networks. These issues can be addressed through the development of new or improved storage technologies with higher performance, availability, durability, safety and lower costs. In the present work, micro-grids characterized by the presence of different subsections including renewable plants coupled with batteries storage solution are investigated through the development of a suitable code. Several design conditions and features, related to RES plant, storage system and users, were considered in order to realize a sensitivity analysis aimed to examine, on a yearly base and with one minute time step, interactions among the different micro-grid subsections and to identify the best solutions from both economic and energy point of views. - Highlights: • Storage systems coupling to RES plants is investigated for micro-grids. • Interactions between RES plants, storage batteries and users are analyzed. • Self-consumption increases with storage installation. • Investment pay-back analysis is performed varying plant configurations. • Pay-back reduction up to 30–40% for new RES/Storage integrated installations.

  13. Current experience with support schemes for RES-E in Europe. A regulatory point of view

    Lackner, Ursula

    2006-01-01

    The need to reduce the dependence of the European economy on imported primary energy and the impact of fossil fuels on the environment has encouraged countries to increase the share of renewable energy sources (RES) for electricity supply. EU Directive 2001/77/EC requires EU Member States to take appropriate steps to introduce new incentive mechanisms in order to reach the target of generating 21 % of the electricity in the EU from RES. At the same time EU Directive 2003/54/EC takes significant steps towards establishing a single market in electricity across the EU. Under this directive, European energy regulators have a number of responsibilities. These include the avoidance of discrimination and the promotion of effective competition along with an efficient functioning of the market. One of their main tasks is to ensure that European consumers pay a final electricity price that is as cost reflective as possible. The final price shall also reflect the social and the environmental costs. At the current stage it is not unlikely that the promotion of renewable energy sources will create significant barriers and distortions on the liberalized electricity market. Several issues arising from the implementation of renewable incentive schemes and policies can be identified and are analysed below; - Conflicting targets on EU-Level; - The variation in the level of incentives may be greater among Member States than is justified by the real level of technology costs, or other factors; - Unbalanced burden sharing for final consumers, due to different allocation mechanisms and designs of support schemes; -The regulation and charges for relevant items of the electricity chain, such as connection and balancing costs, vary significantly among Member States and may introduce competitive advantages. The contents of the paper is as follows: 1 Background; 2 Conflicting targets on EU-Level; 3 Different support levels; 4 Unbalanced burden sharing of final customers; 5 Allocation of

    Full Text Available  SAMMENDRAGTre store utenlandske oppfølgingsstudier fra 1994-95 har funnet en U-formet sammenheng mellom selvrapportertalkoholinntak og dødelighet av hjerte-karsykdom. For menn er det vist at tre alkoholenheter(drinker pr. dag og for kvinner én til to, kan redusere risikoen med opptil 50%. Det synes videre som omeffekten er størst hos eldre personer (over 50 år, og de med minst én viktig koronar risikofaktor. En nyoversiktsartikkel konkluderer med at den gunstige effekten er knyttet til alkoholinnholdet og ikke til andrekomponenter for de ulike alkoholtypene. Det er presentert norske spørreskjema fra 1977 og fram til i dagvedrørende alkohol. Disse er av svært ujevn kvalitet, bl.a. uten spørsmål om mengde alkohol eller type, ogspørsmålene har variert over tid og fra fylke til fylke. Tverrsnittsdata fra Oppland (1986-88 for menn ogkvinner 40-54 år viser en positiv sammenheng mellom alkoholinntak og HDL-kolesterol for begge kjønn ogfor systolisk blodtrykk for menn, sterkest for drikkere av brennevin og øl. For kvinner er det en U-formetsammenheng mellom drikkere av vin og øl og systolisk blodtrykk.

For men it was shown that three units a day and forwomen one to two units can reduce mortality risk with 50%. The effect was stronger in older people (above50 years and those at greater risk for coronary heart disease. The conclusion, in a recent review, was that thebenefit is from alcohol rather than from other components of each type of drink. Norwegian questionnairesfrom 1977 to 1995 on alcohol are commented upon. The quality of these questions varies; many do notaccount for the amount of intake or the type of alcohol, and they have not been identical from screening toscreening and between counties. Cross-sectional results from Oppland (1986-88 for men and women aged40-54 years, indicated a positive relation between alcohol intake and HDL-cholesterol for both sexes, forsystolic blood pressure in men, strongest for consumers of spirits and beer. A U-shaped association betweenintake of wine and beer with systolic blood pressure was seen in women. A follow-up study with cardiovasculardeath as endpoint indicated a higher risk for men drinking beer during the last week, and a lower risk forthose drinking wine/spirits, compared with men not answering the questions about alcohol intake.1996; 6 (1: 69-71.

    Directory of Open Access Journals (Sweden)

    Evangelos Rikos

    2017-07-01

    Full Text Available Future power systems control will require large-scale activation of reserves at distribution level. Despite their high potential, distributed energy resources (DER used for frequency control pose challenges due to unpredictability, grid bottlenecks, etc. To deal with these issues, this study presents a novel strategy of power frequency characteristic dynamic adjustment based on the imbalance state. This way, the concerned operators become aware of the imbalance location but also a more accurate redistribution of responsibilities in terms of reserves activations is achieved. The proposed control is based on the concept of “cells” which are power systems with operating capabilities and responsibilities similar to control areas (CAs, but fostering the use of resources at all voltage levels, particularly distribution grids. Control autonomy of cells allows increased RES hosting. In this study, the power frequency characteristic of a cell is adjusted in real time by means of a fuzzy controller, which curtails part of the reserves, in order to avoid unnecessary deployment throughout a synchronous area, leading to a more localised activation and reducing losses, congestions and reserves exhaustion. Simulation tests in a four-cell reference power system prove that the controller significantly reduces the use of reserves without compromising the overall stability.

  20. In Search of the 'New Informal Legitimacy' of Médecins Sans Frontières.

    2012-04-01

    FOR MEDICAL HUMANITARIAN ORGANIZATIONS, MAKING THEIR SOURCES OF LEGITIMACY EXPLICIT IS A USEFUL EXERCISE, IN RESPONSE TO: misperceptions, concerns over the 'humanitarian space', controversies about specific humanitarian actions, challenges about resources allocation and moral suffering among humanitarian workers. This is also a difficult exercise, where normative criteria such as international law or humanitarian principles are often misrepresented as primary sources of legitimacy. This essay first argues for a morally principled definition of humanitarian medicine, based on the selfless intention of individual humanitarian actors. Taking Médecins Sans Frontières (MSF) as a case in point, a common source of moral legitimacy for medical humanitarian organizations is their cosmopolitan appeal to distributive justice and collective responsibility. More informally, their legitimacy is grounded in the rightfulness of specific actions and choices. This implies a constant commitment to publicity and accountability. Legitimacy is also generated by tangible support from the public to individual organizations, by commitments to professional integrity, and by academic alliances to support evidence-based practice and operational research.

    Recently megalopolises have become centres of economy development worldwide. Gradual growth in energy consumption and thereafter - enormous power production and delivery to sustain metropolis’ needs entailed, rapid increase in emissions of hazardous substances in quantities, no longer tolerable for secure residence in majority of these cities. Ekaterinburg, is one of them. In order to abridge harmful pollution in Ekaterinburg and further centralize economic importance of the city, this paper proposes to implement the concept of urban sustainable development/ref. / by introducing alternative energy sources, which would progressively displace traditional fossil fuels. A number of actual cases, where the concept was successfully implemented, were studied and analysed to demonstrate how different shares of renewables can become effective substitutes to conventional energy sources in the cities strongly dependent on them: 1. Energy strategy of Pecs (Hungary); 2. International low carbon city (ILCC) project (Shenzhen, China); 3. Electric power system template of Tangshan city (China). Further, regional environmental and economic specifics of Ekaterinburg were studied to understand power consumption needs and energy generation possibilities, which led authors to conclude on the alternative energy sources feasibility, plot specific flow chart for RES implementation in Ekaterinburg’s power network and outline recommendations for future works.

    Operational research (OR) has become a hot topic at national meetings, international conferences and donor fora. The International Union Against Tuberculosis and Lung Disease (The Union) and Médecins Sans Frontières (MSF) Operational Centre Brussels strongly promote and implement OR with colleagues in low- and middle-income countries. Here we describe how the two organisations define OR, and explain the guiding principles and methodology that underpin the strategy for developing and expanding OR in those countries. We articulate The Union's and MSF's approach to supporting OR, highlighting the main synergies and differences. Then, using the Malawi National Tuberculosis Control Programme as an example, we show how OR can be embedded within tuberculosis control activities, leading to changes in policy and practice at the national level. We discuss the difficult, yet vitally important, issue of capacity building, and share our vision of a new paradigm of product-related training and performance-based OR fellowships as two ways of developing the necessary skills at country level to ensure research is actually performed. Finally, we highlight the need to consider and incorporate into practice the ethical components of OR. This is a key moment to be involved in OR. We are confident that in partnership with interested stakeholders, including the World Health Organization, we can stimulate the implementation of quality, relevant OR as an integral part of health service delivery that in turn will lead to better health for people, particularly for those living in the poorer parts of the world.

    Layered rhenium disulfide (ReS 2 ) field effect transistors (FETs), with thickness ranging from few to dozens of layers, are demonstrated on 20 nm thick HfO 2 /Si substrates. A small threshold voltage of -0.25 V, high on/off current ratio of up to ∼10 7 , small subthreshold swing of 116 mV/dec, and electron carrier mobility of 6.02 cm 2 /V·s are obtained for the two-layer ReS 2 FETs. Low-frequency noise characteristics in ReS 2 FETs are analyzed for the first time, and it is found that the carrier number fluctuation mechanism well describes the flicker (1/f) noise of ReS 2 FETs with different thicknesses. pH sensing using a two-layer ReS 2 FET with HfO 2 as a sensing oxide is then demonstrated with a voltage sensitivity of 54.8 mV/pH and a current sensitivity of 126. The noise characteristics of the ReS 2 FET-based pH sensors are also examined, and a corresponding detection limit of 0.0132 pH is obtained. Our studies suggest the high potential of ReS 2 for future low-power nanoelectronics and biosensor applications.

  14. Costs and risks of the import of RES statistics by the Dutch government

    Energy Technology Data Exchange (ETDEWEB)

    Klessmann, C.; De Jager, D.; Gephart, M.; Winkel, T.

    2012-11-15

    This paper presents a first estimate of the costs and risks of a potential import of renewable energy statistics by the Dutch Government in order to meet the binding renewable energy (RE) target of 14% by 2020. Recently, the new government has announced that it will increase the ambition from 14% to 16%. Progress so-far has been slow however and meeting these targets requires near to maximum realisable deployment rates of all relevant technologies. It points at the necessity to increase national policy measures (spatial, political, financial, etc.) for all renewable energy technologies or alternatively, to apply the cooperation mechanisms and/or import RES statistics from other countries. It is generally assumed that imported RE statistics, through the cooperation mechanisms of the European RES Directive, will have lower costs than supporting the potentially more expensive domestic technologies that would be needed to meet the targets fully by domestic production. This paper shows that this assumption is questionable, and that the risks of pursuing an import-strategy may be significant. The analysis shows that the use of statistical transfers, which in principle may be a viable option for realising part of the Dutch RE target, is linked to high uncertainties. Important aspects contributing to these uncertainties are: The effectiveness and efficiency of policies in the European Member States to meet domestic RE targets by and up to 2020, and hence the related surplus/shortfall of RE production and resulting market prices for statistical transfers; The price setting mechanisms that will be established between Member States, including the anticipated cost of infringement in case of non-fulfilment of the 2020 targets. Imports will likely be charged against the market prices for (statistical) transfers, not against the cost prices of RE technologies. The price of statistical transfers can be expected to be higher in the case of a clear 'buyer market' in which

    Full Text Available Os resíduos agroindustriais geralmente apresentam grandes concentrações de materiais orgânicos que, se manejados de forma inadequada, podem poluir e/ou contaminar o solo, a água e o ar. A técnica de compostagem tem se mostrado um processo eficiente na busca pela minimização da problemática ambiental associada aos resíduos orgânicos e na redução do volume de resíduos descartados em lixões e aterros sanitários. O principal objetivo deste trabalho consiste na utilização de parâmetros físico-químicos para verificar a maturação de compostos orgânicos obtidos a partir de resíduos agroindustriais da região de Pombal, um município localizado no semiárido paraibano. Para obtenção dos compostos orgânicos, cascas de bananas, estercos ovinos e podas de marmeleiro e jurema-preta foram triturados e misturados para montar duas pilhas de compostagem, sendo uma depositada em solo compactado e outra sobre um pátio pavimentado com concreto. Os parâmetros utilizados na avaliação da maturação foram: temperatura, relação C/N, condutividade elétrica, pH e demanda química de oxigênio. Os resultados sugerem que os compostos orgânicos estudados estão maturados, indicando que estes simples métodos são considerados seguros para verificação de processos de compostagem conduzidos em regiões sujeitas às condições semiáridas.

    Reticuloendothelial system (RES) depression has been correlated with diminished resistance to trauma, shock, and sepsis in man and animals. Previous studies have related the depression of RES hepatic Kupffer cell phagocytic function after trauma to diminished bioassayable opsonic activity. The present study determined if the loss of biological activity and RES alteration correlated with immunoreactive serum opsonic alpha 2 SB glycoprotein levels after trauma. Serum opsonic activity was measured by liver slice bioassay, and immunoreactive opsonic protein was measured by rocket electroimmunoassay. RE function was determined by colloid clearance over a 24-hour post-trauma period. Anesthetized rats (250-300 gm) subjected to sublethal or severe (greater than LD50) whole-body NCD trauma were the shock models investigated. Immunoreactive levels in 63 rats prior to injury were 518 +/- 24 microgram/ml. Neither biological nor immunoreactive levels were altered over 24 hours in anesthetized sham-traumatized controls. Temporal alteration in the initial decrease and recovery pattern of biologically active and immunoreactive opsonic protein levels significantly correlated following both sublethal and severe injury. Moreover, the patterns of immunoreactive levels of the opsonic protein correlated with the functional phagocytic activity of the RES as determined by vascular clearance of a test dose of blood-borne radiolabeled particulates. This glycoprotein falls after trauma, and the magnitude and duration of the decline increases with severity of injury. Immunoreactive opsonic alpha 2 SB glycoprotein appears to be an accurate measurement of circulating opsonic activity and RE Kupffer cell function after trauma, especially with respect to clearance. Thus, immunoreactive opsonic protein warrants clinical consideration as a noninvasive measure of reticuloendothelial systemic defense in patients after trauma and burn.

    This study aims to meet the need for scientifically robust information on the gross effects (direct and indirect) as well as on the net effects (including both conventional replacement and budget effects) of renewable energy policies in Europe. Furthermore, the future development of RES in Europe will take place against the background of a global market for RES technology. This global market and the potential share of European industries in it will play a critical role in the potentials for growth and employment. This study aims to provide a sound scientific analysis of these issues. This report is divided into four main parts, A, B, C and D. While the first three covers the introduction, the theoretical approach, the modelling steps and structure of the report, the fourth part, part D, discusses in detail the models and results of the projects. It begins with chapter D 1 which describes past RES deployment and its costs. Then follows the past macroeconomic impacts presented by gross effects on employment and value added (D 2). Thereafter, the future potential (D 3) and future deployment (D 4) of renewable energy sources (RES) are discussed. Before the presentation of the future gross and net effects, the five scenarios used in the macro-economic models (D 5) are explained in detail. Finally we depict the future gross and net impacts on employment and GDP in D 6 and D 7, respectively. The comparison between the results of the two models and our conclusion for the study follows in chapter D 8 and 9

    Aicardi-Goutières syndrome (AGS) is a genetic encephalopathy whose clinical features mimic those of acquired in utero viral infection. AGS exhibits locus heterogeneity, with mutations identified in genes encoding the 3′→5′ exonuclease TREX1 and the three subunits of the RNASEH2 endonuclease complex. To define the molecular spectrum of AGS, we performed mutation screening in patients, from 127 pedigrees, with a clinical diagnosis of the disease. Biallelic mutations in TREX1, RNASEH2A, RNASEH2B, and RNASEH2C were observed in 31, 3, 47, and 18 families, respectively. In five families, we identified an RNASEH2A or RNASEH2B mutation on one allele only. In one child, the disease occurred because of a de novo heterozygous TREX1 mutation. In 22 families, no mutations were found. Null mutations were common in TREX1, although a specific missense mutation was observed frequently in patients from northern Europe. Almost all mutations in RNASEH2A, RNASEH2B, and RNASEH2C were missense. We identified an RNASEH2C founder mutation in 13 Pakistani families. We also collected clinical data from 123 mutation-positive patients. Two clinical presentations could be delineated: an early-onset neonatal form, highly reminiscent of congenital infection seen particularly with TREX1 mutations, and a later-onset presentation, sometimes occurring after several months of normal development and occasionally associated with remarkably preserved neurological function, most frequently due to RNASEH2B mutations. Mortality was correlated with genotype; 34.3% of patients with TREX1, RNASEH2A, and RNASEH2C mutations versus 8.0% RNASEH2B mutation–positive patients were known to have died (P=.001). Our analysis defines the phenotypic spectrum of AGS and suggests a coherent mutation-screening strategy in this heterogeneous disorder. Additionally, our data indicate that at least one further AGS-causing gene remains to be identified. PMID:17846997

    Full Text Available La recherche sur laquelle repose cet article analyse la place des coutumes des marges de l’apprentissage universitaire dans la construction du personnage du médecin spécialiste français, dans lequel l’internat et les manières à y apprendre sont centrales. Environ cent entretiens ethnographiques avec des spécialistes d’âges et d’exercices variés ont été menés. L’internat concerne les futurs spécialistes, reçus au concours de l’internat qui donne accès, après 6 années d’étude communes à tous les médecins, à une formation propre de 4-6 années supplémentaires, pendant laquelle ils apprennent non seulement leur profession auprès de malades et de patrons, mais aussi les manières constitutives du personnage du spécialiste, en fréquentant internes et internats. Chaque midi à table, les internes acquièrent ces manières de salle de garde. À travers l’apprentissage de règles contraignantes et souvent paradoxales, de savoir-dire et de savoir-faire, autrement dit de savoir-être propres au groupe, ils vont acquérir une compétence spécifique : nouveau calendrier, nouvelle langue, nouveau code comportemental, nouvelle hiérarchie, nouveaux devoirs… dont le non-respect est sanctionné par des gages codifiés. La mise en place de rituels collectifs fondant la communauté, l’application de codes précis, la valorisation de modèles identificatoires permettent à chacun de prendre place, de s’impliquer selon une organisation concentrique, de donner sens aux expériences en cours en les intégrant dans une logique initiatique. Cet apprentissage se singularise par le fait qu’il coexiste avec celui d’un langage médical parfois complexe, d’attitudes professionnelles codifiées, d’un sens de la hiérarchie aiguisé, d’un code de déontologie rigoureux… autant de caractéristiques propres au monde hospitalo-universitaire.This paper is based on a research on the importance of customs learned in the

    ReS2, a layered two-dimensional material popular for its in-plane anisotropic properties, is emerging as one of the potential candidates for flexible electronics and ultrafast optical applications. It is an n-type semiconducting material having a layer independent bandgap of 1.55 eV. In this paper we have characterized the intrinsic electronic noise level of few-layer ReS2 for the first time. Few-layer ReS2 field effect transistor devices show a 1/f nature of noise for frequency ranging over three orders of magnitude. We have also observed that not only the electrical response of the material is anisotropic; the noise level is also dependent on direction. In fact the noise is found to be more sensitive towards the anisotropy. This fact has been explained by evoking the theory where the Hooge parameter is not a constant quantity, but has a distinct power law dependence on mobility along the two-axes direction. The anisotropy in 1/f noise measurement will pave the way to quantify the anisotropic nature of two-dimensional (2D) materials, which will be helpful for the design of low-noise transistors in future.

  5. Applying Rock Engineering Systems (RES approach to Evaluate and Classify the Coal Spontaneous Combustion Potential in Eastern Alborz Coal Mines

    Full Text Available Subject analysis of the potential of spontaneous combustion in coal layers with analytical and numerical methods has been always considered as a difficult task because of the complexity of the coal behavior and the number of factors influencing it. Empirical methods, due to accounting for certain and specific factors, have not accuracy and efficiency for all positions. The Rock Engineering Systems (RES approach as a systematic method for analyzing and classifying is proposed in engineering projects. The present study is concerned with employing the RES approach to categorize coal spontaneous combustion in coal regions. Using this approach, the interaction of parameters affecting each other in an equal scale on the coal spontaneous combustion was evaluated. The Intrinsic, geological and mining characteristics of coal seams were studied in order to identifying important parameters. Then, the main stages of implementation of the RES method i.e. interaction matrix formation, coding matrix and forming a list category were performed. Later, an index of Coal Spontaneous Combustion Potential (CSCPi was determined to format the mathematical equation. Then, the obtained data related to the intrinsic, geological and mining, and special index were calculated for each layer in the case study (Pashkalat coal region, Iran. So, the study offers a perfect and comprehensive classification of the layers. Finally, by using the event of spontaneous combustion occurred in Pashkalat coal region, an initial validation for this systematic approach in the study area was conducted, which suggested relatively good concordance in Pashkalat coal region.

    ReS 2 films are considered as a promising candidate for optoelectronic applications due to their direct band gap character and optical/electrical anisotropy. However, the direct band gap in a narrow spectrum and the low absorption of atomically thin flakes weaken the prospect for light-harvesting applications. Here, we developed an efficient approach to enhance the performance of a ReS 2 -based phototransistor by coupling CdSe-CdS-ZnS core-shell quantum dots. Under 589 nm laser irradiation, the responsivity of the ReS 2 phototransistor decorated with quantum dots could be enhanced by more than 25 times (up to ∼654 A/W) and the rising and recovery time can be also reduced to 3.2 and 2.8 s, respectively. The excellent optoelectronic performance is originated from the coupling effect of quantum dots light absorber and cross-linker ligands 1,2-ethanedithiol. Photoexcited electron-hole pairs in quantum dots can separate and transfer efficiently due to the type-II band alignment and charge exchange process at the interface. Our work shows that the simple hybrid zero- and two-dimensional hybrid system can be employed for photodetection applications.

    Efficient biofilm formation and root colonization capabilities facilitate the ability of beneficial plant rhizobacteria to promote plant growth and antagonize soilborne pathogens. Biofilm formation by plant-beneficial Bacillus strains is triggered by environmental cues, including oxygen deficiency, but the pathways that sense these environmental signals and regulate biofilm formation have not been thoroughly elucidated. In this study, we showed that the ResDE two-component regulatory system in the plant growth-promoting rhizobacterium Bacillus amyloliquefaciens strain SQR9 senses the oxygen deficiency signal and regulates biofilm formation. ResE is activated by sensing the oxygen limitation-induced reduction of the NAD + /NADH pool through its PAS domain, stimulating its kinase activity, and resulting in the transfer of a phosphoryl group to ResD. The phosphorylated ResD directly binds to the promoter regions of the qoxABCD and ctaCDEF operons to improve the biosynthesis of terminal oxidases, which can interact with KinB to activate biofilm formation. These results not only revealed the novel regulatory function of the ResDE two-component system but also contributed to the understanding of the complicated regulatory network governing Bacillus biofilm formation. This research may help to enhance the root colonization and the plant-beneficial efficiency of SQR9 and other Bacillus rhizobacteria used in agriculture. IMPORTANCE Bacillus spp. are widely used as bioinoculants for plant growth promotion and disease suppression. The exertion of their plant-beneficial functions is largely dependent on their root colonization, which is closely related to their biofilm formation capabilities. On the other hand, Bacillus is the model bacterium for biofilm study, and the process and molecular network of biofilm formation are well characterized (B. Mielich-Süss and D.

  16. The impact of rhetoric and education on the "Res Gestae" of Ammianus Marcellinus

    Science.gov (United States)

    Alvarez, Pablo

    The aim of this thesis is to explore and underline the impact of education and rhetoric on the Res Gestae of Ammianus Marcellinus. I will examine the concept of education in two different aspects. First, I will determine the role of education in regards to Ammianus' early life by describing the cultural climate in the East in the fourth century (Introduction and chapter 1). In this analysis, I will argue that the historian's familiarity with Latin suggests an early acquaintance with the language, indicating that he should not be invariably associated with earlier Greek historians. Second, I will look at how the content of the curriculum is reflected in the RG, explaining how literary sources shaped the composition of the historian's digressions on geography (Chapter 3) and astronomy (Chapter 4). In the past, scholars have examined Ammianus' cultural digressions as an example of the tension between things seen and things read. In my argumentation, I will concentrate on explaining the reasons why Ammianus often tended to rely on literary works rather than observation. I will show that the explanation greatly lies in the content of the curriculum. Concerning the role of rhetoric, I will examine how rhetorical training is articulated in the RG. In Chapter 2, I will show that Ammianus' selection of historical material can be explained in light of the ancient theory of styles. In this context, I will study the role of a rhetorical device designed to raise the emotions of readers by bringing the scene before their eyes: enargeia. In Chapters 3 and 4, I will demonstrate that the cultural digressions in the RG are mostly the product of cultural stereotypes and literary influences. In Chapter 5, I will show the impact of rhetorical treatises on some passages of the RG, arguing that the traditional classification of oratory into deliberative, epideictic and judicial is echoed in both the speeches and the historical narrative. To conclude: the main purpose of my dissertation

    Rock Engineering Systems (RES) is an approach to discover the important characteristics and interactions of a complex problem. Recently RES has been applied to identify features, events and processes (FEPs) for performance analysis of nuclear waste repositories. The RES methodology was applied to identify FEPs for the near-field analysis of the copper-steel canister for spent fuel disposal. The aims of the exercise were to learn and test the RES methodology and, secondly, to find out how much the results differ when RES is applied by two different groups on the same problem. A similar exercise was previously carried out by a SKB group. A total of 90 potentially significant FEPs were identified. The exercise showed that the RES methodology is a practicable tool to get a comprehensive and transparent picture of a complex problem. The approach is easy to learn and use. It reveals the important characteristics and interactions and organizes them in a format easy to understand. (9 refs., 5 figs., 3 tabs.)

    Full Text Available Tem sido cada vez maior a preocupação das empresas do setor florestal em adotar práticas pautadas na conservação do solo e da água. Nesse sentido, este trabalho teve por objetivo avaliar o impacto do manejo dos resíduos da colheita, do preparo do solo e do uso de resíduos industriais, na fertilidade do solo e produtividade de eucalipto. O experimento foi iniciado após o corte raso de um plantio comercial de EUCALYPTUS GRANDIS, onde os resíduos da colheita foram manejados (retirada de todo o resíduo; remoção da casca e dos galhos com diâmetro superior a 3,0 cm; e manutenção de todos os resíduos na superfície do solo. Em seguida, realizaram-se o preparo do solo (com subsolador de uma e três hastes, a aplicação dos resíduos industriais (resíduo de celulose e cinzas na superfície do solo e o plantio de mudas de EUCALYPTUS GRANDIS X E. UROPHYLLA Foi utilizado o delineamento em blocos ao acaso, contendo oito tratamentos e quatro repetições. Os tratamentos consistiram da combinação dos diferentes tipos de manejo dos resíduos da colheita, preparo do solo e aplicação dos resíduos industriais. Cada parcela experimental foi composta por cinco linhas com 19 plantas cada. Aos 83 meses após o plantio, foram medidos o DAP (diâmetro à altura do peito e a altura das árvores, para cálculo do volume de madeira. A fertilização e a manutenção dos resíduos da colheita florestal elevaram os teores de Ca2+ e Mg2+ trocáveis no solo. A manutenção total dos resíduos vegetais na área após a colheita resultou em aumento de 71,7 m³ ha-1 de madeira, quando comparado à remoção de todos os resíduos. Não houve diferença entre os modos de preparo do solo com subsolador de uma e três hastes, quanto ao volume de madeira. Os maiores volumes de madeira foram obtidos dos tratamentos que receberam as maiores quantidades de resíduo de celulose e cinzas, ao mesmo tempo em que foi mantida parte do resíduo vegetal após a colheita

  1. Acompanhamento da hidratação de cimento Portland simples com resíduo de bauxita

    Full Text Available Resumo A substituição parcial de cimento Portland por resíduo de bauxita (RB resulta em produtos com, no mínimo, propriedades similares às dos produtos fabricados com o ligante puro. No entanto, as interações físico-químicas entre os diferentes tipos de cimento e o RB durante a reação de hidratação ainda é pouco explorada em literatura. A elevada quantidade de sódio e a presença de Al2O3, SiO2 e Fe2O3 são fatores que afetam a formação dos produtos hidratados e dependem do tipo de cimento utilizado na mistura. Sendo assim, este trabalho foi realizado com o objetivo de avaliar o impacto da presença do resíduo de bauxita em associação ao cimento Portland simples nas primeiras idades de hidratação. Calorimetria de condução isotérmica, difração de raios X, análise termogravimétrica e espectroscopia de infravermelho foram as técnicas escolhidas para o monitoramento. Os resultados ilustraram que a presença do resíduo coletado na planta da Alcoa (Poços de Caldas aumenta o tempo de indução, o consumo de portlandita, e as quantidades de etringita e monossulfoaluminato formadas. Ao mesmo tempo, houve formação de silicoaluminato de sódio e bicarbonato de sódio, devido às reações com silicatos, aluminatos e com o carbonato do cimento.

    The aim of the present study was to assess the precision of the OMNI-RES scale to predict energy cost (EC) at low intensity in four resistance exercises (RE). 17 male recreational body builders (age = 26.6 ± 4.9 years; height = 177.7 ± 0.1 cm; body weight = 79.0 ± 11.1 kg and percent body fat = 10.5 ± 4.6%) served as subjects. Initially tests to determine 1RM for four resistance exercises (bench press, half squat, lat pull down and triceps extension) were administered. Subjects also performed resistance exercise at 12, 16, 20, and 24% of 1RM at a rate of 40 bpm until volitional exhaustion. Oxygen uptake (VO2) and rate of perceived exertion (RPE) using the OMNI-RES were obtained during and after all RE. EC was calculated using VO2 and the caloric values of VO2 for non-protein RER. Regression analyses were performed for every RE, using EC as the dependent and RPE as the predictor variable. The triceps extension, lat pull down and bench press, RPE correlated strongly with EC (R > 0.97) and predicted EC with a error of less than 0.2 kcal.min−1. In conclusion, RPE using the OMNI-RES scale can be considered as an accurate indicator of EC in the bench press, lat pull down and triceps extension performed by recreational bodybuilders, provided lower intensities are used (up to 24% of 1-RM) and provided each set of exercise is performed for the maximal sustainable duration. It would be interesting in future studies to consider having the subjects exercise at low intensities for longer durations than those in the present study. PMID:23486188

    Fertile soils are central resources for the production of biomass and provision of food and energy. A growing world population and latest climate targets lead to an increasing demand for both, food and bio-energy, which require preserving and improving the long-term productivity of soils as a bio-economic resource. At the same time, other soil functions and ecosystem services need to be maintained. To render soil management sustainable, we need to establish a scientific knowledge base about complex soil system processes that allows for the development of model tools to quantitatively predict the impact of a multitude of management measures on soil functions. This, finally, will allow for the provision of site-specific options for sustainable soil management. To face this challenge, the German Federal Ministry of Education and Research recently launched the funding program "Soil as a Natural Resource for the Bio-Economy - BonaRes". In a joint effort, ten collaborative projects and the coordinating BonaRes Centre are engaged to close existing knowledge gaps for a profound and systemic understanding of soil functions and their sensitivity to soil management. This presentation provides an overview of the concept of the BonaRes Centre which is responsible for i) setting up a comprehensive data base for soil-related information, ii) the development of model tools aiming to estimate the impact of different management measures on soil functions, and iii) establishing a web-based portal providing decision support tools for a sustainable soil management. A specific focus of the presentation will be laid on the so-called "knowledge-portal" providing the infrastructure for a community effort towards a comprehensive meta-analysis on soil functions as a basis for future model developments.

    2005-01-01

    Full Text Available Uma das características do sistema de plantio direto é o acúmulo de resíduos culturais na superfície do solo. Embora as recomendações técnicas preconizem a remoção desses resíduos antes da amostragem de solo, isso não ocorre quando a amostragem é efetuada utilizando o quadriciclo. Os resíduos culturais também podem ser misturados com a amostra de solo quando esse é amostrado com o trado manual e esses resíduos não são removidos da superfície do solo. Neste trabalho, estudou-se a influência dos resíduos culturais da superfície do solo nos resultados da análise de solo sob plantio direto. Amostraram-se solos com e sem a remoção de resíduos culturais da superfície. Esses procedimentos foram testados em solos contendo baixo e alto teor de argila, amostrados com o trado calador e o quadriciclo, após o cultivo de soja e milho. A influência dos resíduos culturais no resultado da análise de solo foi, em geral, pouco expressiva, variando com o tipo de amostrador, de resíduo e teor de argila do solo. Nas amostras coletadas com o quadriciclo, foi possível detectar diferenças no teor de matéria orgânica (MO em função dos procedimentos de amostragem testados, entretanto, isso não ocorreu nas amostras coletadas com o calador. Na presença dos resíduos culturais, o teor de MO aumentou em 4g kg-1 (solo com baixo teor de argila e cultivado com soja e em 5g kg-1 (solo com alto teor de argila e cultivado com milho. Com exceção dos teores de MO, a presença dos resíduos culturais não interferiu na interpretação dos outros atributos analisados.

    Full Text Available FUNDAMENTO: A aterosclerose é uma doença inflamatória crônica de origem multifatorial que ocorre em resposta à agressão endotelial. O fungo Monascus ruber apresenta atividade hipocolesterolêmica e polifenóis presentes no resíduo de café apresentam atividade antioxidante, podendo auxiliar na prevenção de doenças cardiovasculares. O resíduo de café possui quantidade significativa de açúcares fermentescíveis, constituindo-se em substrato apropriado para o cultivo de fungos. OBJETIVO: O objetivo deste estudo foi avaliar o efeito dos resíduos de café seco e fermentado por Monascus ruber no metabolismo lipídico de camundongos knockout Apo E. MÉTODOS: O ensaio biológico foi realizado com 30 camundongos knockout para o gene Apo E, divididos em cinco grupos e submetidos a diferentes tratamentos. Foi realizada a prospecção fitoquímica e quantificação de compostos fenólicos dos resíduos fermentado e sem fermentar. O soro dos animais foi analisado utilizando kits enzimáticos e o tecido aórtico incluso em parafina e corado com H/E para realização da análise histopatológica. RESULTADOS: O resíduo de café sem fermentar 2%, em relação ao grupo controle, diminuiu em 42% o nível sérico de triacilgliceróis e em aproximadamente 41% a fração VLDL-c. Os grupos dos animais alimentados com 10% de resíduo não fermentado e 2% de resíduo fermentado diminuíram a área de lesão 10,5% e 15,4%, respectivamente, quando comparados ao controle. O resíduo fermentado apresentou um teor de compostos fenólicos superior ao resíduo não fermentado. CONCLUSÃO: O presente estudo mostra que a fermentação do resíduo de café apresenta potencial efeito benéfico sobre as doenças cardiovasculares, especialmente a aterosclerose.

    Aicardi-Goutières syndrome is a mendelian mimic of congenital infection and also shows overlap with systemic lupus erythematosus at both a clinical and biochemical level. The recent identification of mutations in TREX1 and genes encoding the RNASEH2 complex and studies of the function of TREX1 in DNA metabolism have defined a previously unknown mechanism for the initiation of autoimmunity by interferon-stimulatory nucleic acid. Here we describe mutations in SAMHD1 as the cause of AGS at the AGS5 locus and present data to show that SAMHD1 may act as a negative regulator of the cell-intrinsic antiviral response.

    Full Text Available La marque de la séparation des Eglises et de l’Etat semble en France suffisamment forte pour que les points de contact entre service public et prière soient rares et plutôt indirects, à partir de comportements qui n’ont en général pas pour objet d’opposer le seul acte de prière aux normes juridiques et sociales environnantes. Néanmoins à partir des systèmes juridiques et des pratiques d’autres pays d’Europe, les arrêts pragmatiques de la Cour européenne des droits de l'homme révèlent une retenue comparable, même si leur fondement est nécessairement différent.Dans son ensemble, la jurisprudence de la Cour permet de constater que les Etats membres du Conseil de l’Europe ont parfois à l’égard de la prière des attitudes restrictives qui dépendent soit d’une sorte de protection de la religion dominante par rapport aux cultes minoritaires, soit d’un refus implicite de l’athéisme. En revanche, la notion de service public, n’étant pas universellement reconnue en Europe, ne fournit pas un cadre de raisonnement juridique signifiant dans les arrêts, ce qui ne permet d’identifier les rapports entre prières et service public que par le biais du contexte dans lequel se produisent les actes de prière.The mark of the separation between the Church and the State seems sufficiently strong in France so that the points of contact between the civil service and prayer are rare and rather indirect, starting with behaviours which do not have in general aim to oppose the sole act of prayer to the legal and social standards surrounding (First part.

    Full Text Available RESUMO Com o crescimento da população e o consequente aumento da urbanização, o lançamento de resíduos sólidos nos sistemas de drenagem urbana tem aumentado nos últimos anos, principalmente nas regiões periféricas das cidades. Este estudo teve como objetivo qualificar e quantificar os resíduos sólidos no arroio Cancela-Tamandai, localizado em área urbana, no município de Santa Maria (RS. Foram coletados ao todo 1.153,2 kg de resíduos sólidos com uma precipitação pluviométrica total para o período de novembro de 2012 a janeiro de 2013 de 518,94 mm, sendo, desses, 93,9% composto por matéria orgânica, sendo a maioria vegetação. O arroio Cancela-Tamandai apresentou uma carga de resíduos sólidos igual a 17,27 ou 0,424 kg.hab-1.ano-1. A curva de previsão de resíduos sólidos orgânicos drenados em função da precipitação pluviométrica apresentou correlação de 76,4%, um parâmetro importante para a tomada de decisão dos gestores municipais em relação aos resíduos sólidos gerados. Assim, conceber estratégias para o monitoramento desses resíduos representa passo importante na busca de soluções que visem um melhor gerenciamento de bacias hidrográficas urbanas.

Esses resíduos foram colhidos em três estádios do desenvolvimento reprodutivo do sorgo: florescimento, enchimento de grãos e maturação. Os tratamentos estudados constaram da deposição desses resíduos na superfície do solo ou da sua total incorporação na proporção de 4 g kg-1 de matéria seca no solo (LEd, fase cerrado. Nos tratamentos com planta, mantiveram-se três plantas de soja (cv. Doko em vasos com capacidade para 3 kg de solo. Nos tratamentos sem planta, o solo foi amostrado semanalmente para avaliação das formas de N. Após a colheita da soja, amostras de planta e de solo, de cada tratamento, foram retiradas para determinar a absorção total de N e a influência desses resíduos no N disponível extraído com KCl 2 mol L-1. Os resultados revelaram que alguns resíduos culturais de sorgo afetaram, independentemente do estádio de colheita, o desenvolvimento da soja, a absorção de N, o peso de nódulos e a biomassa microbiana do solo. Tais efeitos também foram dependentes do método de incorporação do resíduo. O teor de carbono imobilizado pela biomassa foi maior quando os resíduos de sorgo foram distribuídos na superfície do solo.

Durante 24 horas, larvas de Aedes aegypti e Culex quinquefasciatus foram expostas a concentrações diferentes do extrato da planta para determinar as concentrações letais. Para A. aegypti foi constatada a CL50 em 322ppm e para C. quinquefasciatus em 183ppm. Foi investigada a ação de saponinas existentes na planta, ficando evidenciado que o resíduo de A. sisalana é ativo através da interação de vários dos seus componentes. Este extrato poderá ser utilizado em campo, na concentração de 100ppm para C. quinquefasciatus com um aumento do tempo de exposição para três dias, obtendo-se uma mortalidade de 100% das larvas. Este produto, porém, não é recomendado para o controle de A. aegypti, devido à necessidade de uma alta concentração para a obtenção de 100% de mortalidade das larvas e ao fato destas se desenvolverem preferencialmente em água potável.

  1. Modulation of LINE-1 and Alu/SVA Retrotransposition by Aicardi-Goutières Syndrome-Related SAMHD1

    Full Text Available Long interspersed elements 1 (LINE-1 occupy at least 17% of the human genome and are its only active autonomous retrotransposons. However, the host factors that regulate LINE-1 retrotransposition are not fully understood. Here, we demonstrate that the Aicardi-Goutières syndrome gene product SAMHD1, recently revealed to be an inhibitor of HIV/simian immunodeficiency virus (SIV infectivity and neutralized by the viral Vpx protein, is also a potent regulator of LINE-1 and LINE-1-mediated Alu/SVA retrotransposition. We also found that mutant SAMHD1s of Aicardi-Goutières syndrome patients are defective in LINE-1 inhibition. Several domains of SAMHD1 are critical for LINE-1 regulation. SAMHD1 inhibits LINE-1 retrotransposition in dividing cells. An enzymatic active site mutant SAMHD1 maintained substantial anti-LINE-1 activity. SAMHD1 inhibits ORF2p-mediated LINE-1 reverse transcription in isolated LINE-1 ribonucleoproteins by reducing ORF2p level. Thus, SAMHD1 may be a cellular regulator of LINE-1 activity that is conserved in mammals.

    Full Text Available Les forces électriques s’exerçant sur des polymères granulaires chargés sont mises à profit dans plusieurs processus électrostatiques. La dynamique de charges de surface de ces matériaux est très importante pour ce type de processus. Le but de ce papier est d’analyser l’écoulement des charges à la surface de couches compactes de polymères granulaires, en interprétant les mesures sans contact réalisées par trois sondes de potentiel, de champ et de charge, ayant chacune une taille différente. Des mesures du profile de potentiel à différents instants sont également réalisées afin d’expliquer les différences entre les vitesses de déclin de potentiel, de champ et de charge mesurées par les trois sondes. Les résultats mettent en évidence un écoulement transversal et longitudinal de la charge surfacique.

    This works gives an account of evaluation of white blood cell differential counts via computer aided diagnosis (CAD) system and hematology rules. Leukocytes, also called white blood cells (WBCs) play main role of the immune system. Leukocyte is responsible for phagocytosis and immunity and therefore in defense against infection involving the fatal diseases incidence and mortality related issues. Admittedly, microscopic examination of blood samples is a time consuming, expensive and error-prone task. A manual diagnosis would search for specific Leukocytes and number abnormalities in the blood slides while complete blood count (CBC) examination is performed. Complications may arise from the large number of varying samples including different types of Leukocytes, related sub-types and concentration in blood, which makes the analysis prone to human error. This process can be automated by computerized techniques which are more reliable and economical. In essence, we seek to determine a fast, accurate mechanism for classification and gather information about distribution of white blood evidences which may help to diagnose the degree of any abnormalities during CBC test. In this work, we consider the problem of pre-processing and supervised classification of white blood cells into their four primary types including Neutrophils, Eosinophils, Lymphocytes, and Monocytes using a consecutive proposed deep learning framework. For first step, this research proposes three consecutive pre-processing calculations namely are color distortion; bounding box distortion (crop) and image flipping mirroring. In second phase, white blood cell recognition performed with hierarchy topological feature extraction using Inception and ResNet architectures. Finally, the results obtained from the preliminary analysis of cell classification with (11200) training samples and 1244 white blood cells evaluation data set are presented in confusion matrices and interpreted using accuracy rate, and false

    Full Text Available O uso intensivo de agrotóxicos em culturas de tomates tem causado preocupações quanto à provável contaminação do produto final. Este trabalho teve como objetivo monitorar, por dois anos consecutivos, em quatro propriedades de uma área altamente tecnificada, o uso de agrotóxicos em tomate irrigado durante seu desenvolvimento, quantificar os resíduos dos principais princípios ativos utilizados, e avaliar o grau de contaminação dos frutos colhidos. Foram analisados metamidofós, clorpirifós, captan, clorotalonil, endosulfan, lambda-cialotrina, e cobre. Para avaliar o grau de contaminação dos frutos foi validado um método de análise de resíduos múltiplos capaz de quantificar esses compostos. Os resíduos encontrados foram de fungicidas e inseticidas aplicados nas fases de frutificação e maturação: captan, 0,35 mg/kg, na Fazenda 2; clorotalonil, 0,16 mg/kg e 0,95 mg/kg, nas Fazendas 1 e 2, respectivamente; lambda-cialotrina, 0,03 mg/kg, na Fazenda 2; cobre, 2,03 mg/kg, 3,75 mg/kg e 1,44mg/kg, nas Fazendas 1, 2 e 3, respectivamente, e 0,95 mg/kg, 1,70 mg/kg e 2,31 mg/kg, na Fazenda 4. Não ocorreram resíduos dos inseticidas organofosforados, aplicados principalmente durante o desenvolvimento vegetativo da cultura. Não houve contaminação dos tomates pelos agrotóxicos analisados. Os resíduos que devem ser monitorados são os dos agrotóxicos aplicados na fase de maturação da cultura.The intensive use of pesticide in tomato crops have been causing concern about a possible contamination of the final product. This work aimed at monitoring, for two years, in four farms located in a high technology area, the use of pesticides in irrigated tomato crops, quantifying the main active ingredient residues and evaluating the contamination level of the fruits. The components analised were: methamidophos, chlorpyrifos, captan, chlorothalonil, endosulfan, lambda-cyhalothrin and copper oxychloride. In order to evaluate the contamination

    2013-06-01

    Full Text Available O advento da ISO 24512:2007 suscita discussões muito interessantes em relação ao funcionamento dos sistemas de abastecimento de água em âmbito mundial. No Brasil, a maioria das estações de tratamento de água é convencional de ciclo completo, gerando resíduos complexos e de difícil manejo e disposição. Este trabalho teve como objetivo avaliar de forma crítica a problemática dos resíduos das estações de tratamento de água no Brasil, mediante o estudo da viabilidade de construção e uso de indicadores, tais como aqueles preconizados pela ISO 24512. A grande maioria das estações de tratamento de água analisadas, que refletem um quadro comum no Brasil, não dimensiona a quantidade de resíduos gerados, poucas avaliam suas características e destinam adequadamente esses resíduos, o que dificulta e, em muitos casos, pode impossibilitar o uso de indicadores como ferramentas de gestão. Esse cenário remete ao desafio enfrentado na área de saneamento em relação à gestão dos resíduos em consonância com as normas internacionais.

    The increasing energy challenges faced, in particular, by isolated communities, such as insular communities, call for an integrated, flexible and easy-to-apply methodology aiming at providing a list of renewable energy sources) (RES) projects capable to reduce green house gas (GHG) emissions, satisfy future energy forecasts and reach the objectives of international/national energy directives and obligations, as, for example, the ones set by the Kyoto Protocol by 2010. The EU project EMERGENCE 2010 developed such a methodology that is implemented here in the case study of wind parks in the Dodecanese islands in Greece. The results obtained consist of a final list of financially viable RES wind projects, for which various barriers have been previously identified and assessed. The additional advantages of the proposed methodology is that besides providing as an end result a comprehensive list of RES projects adopted to specific criteria and regional priorities, it also allows space for involving - from early stages - the local community and stakeholders in the decision-making process (participatory planning); in this way, the EMERGENCE 2010 methodology may assist towards the RES promotion and public acceptance, the profitability of RES investments and the regional sustainable development.

    Full Text Available A demanda por produtos de origem animal vem aumentando gradativamente no mundo, e a expectativa é que haja um incremento nos próximos anos, juntamente com a produção. Em consequência disso, ocorre também acréscimo na geração de diferentes tipos de resíduos nas propriedades. Um dos resíduos que são gerados na produção animal são os resíduos de serviço de saúde animal (RSSA. Diante deste cenário, objetivou-se realizar uma revisão sobre o gerenciamento de RSSA. Os RSSA mesmo que produzidos em menor quantidade devem receber cuidado especial devido à capacidade de infectar e contaminar o meio ambiente e o ser humano. O gerenciamento de RSSA é importante para mitigar os impactos ambientais e sanitários. Nas propriedades rurais, é ainda pouco discutido e realizado. É importante buscar medidas para realizar a correta segregação e posterior reciclagem dos RSSA. A disposição final da maior parte destes resíduos é efetuada de forma inadequada. É de fundamental importância à implantação de um plano de gerenciamento de resíduos sólidos e que mais estudos sejam realizados na área.

    Full Text Available O gesso está sendo utilizado em larga escala como revestimento interno de paredes por ser um material barato e de alto desempenho. No entanto, há uma grande geração de resíduo, o que constitui um problema econômico e ambiental. Embora se observe um interesse crescente no uso desse resíduo como revestimento de vedação interna, há um grande desconhecimento a respeito de sua tecnologia de produção, bem como de seu comportamento. O objetivo desta pesquisa é estudar o desempenho desse material através dos ensaios de dureza superficial, resistência à compressão e de aderência, além da apresentação da técnica de execução do revestimento a partir do aproveitamento do resíduo de gesso. Foram realizados ensaios utilizando-se misturas com 0%, 5% e 10% de resíduo com 0,6 mm de diâmetro máximo, e também realizadas visitas técnicas aos canteiros de obras para a avaliação e a determinação da técnica de execução mais apropriada para a aplicação do revestimento. Os resultados mostraram que a adição de resíduos não prejudica excessivamente as propriedades estudadas, sendo admissível até 10% de resíduo de gesso na produção da nova argamassa, respeitando-se as recomendações da técnica construtiva.

    Full Text Available O crescimento populacional tem gerado diversos problemas na sociedade contemporânea. Dentre eles estão o aumento do descarte de resíduos urbanos e a carência de moradia de baixo custo. O objetivo do presente trabalho foi estudar a potencialidade da utilização de dois resíduos sólidos na confecção de pisos flutuantes para redução do ruído de impacto através de parcerias com Furnas Centrais Elétricas e UFG. As amostras foram confeccionadas com o flake de garrafas PET e a raspa de pneus inservíveis aplicados em misturas cimentícias nas proporções de 1:4 e 1:5 (cimento: resíduo. Estas tinham espessuras diferentes sobre as quais tiveram a colocação de um contrapiso móvel com dois tipos de revestimento cerâmico. Para os ensaios foram consultadas a ISO 140-7 quanto aos procedimentos de medição para os níveis de pressão sonora de impacto (L’nT e a ISO 717-2 para a determinação do valor único ponderado (L’nT,w. Dentre os resultados, 5 amostras com PET obtiveram L’nT,w superior às demais amostras. Conclui-se que as amostras com resíduo de PET tiveram desempenho superior às amostras com resíduo de pneu. Contudo, ambos resíduos possuem um uso potencial na aplicação de pisos flutuantes nas proporções estudadas, porém necessitam maiores estudos para aplicação técnica.

  3. The Theos/ComRes survey into public perception of Darwinism in the UK: a recipe for confusion.

    Science.gov (United States)

    Baker, Sylvia

    2012-04-01

    A survey of the general public in the UK, conducted in 2008, suggested that more than half of the British population are unconvinced by Darwinism. That survey, conducted by the polling company ComRes on behalf of the theological think-tank Theos, reported its full findings in March 2009 and found them to be "complex and confused." This paper argues that the confusion identified may have been partly engendered by the way in which the survey questionnaire was constructed and that the survey itself, not simply its respondents, was confused. A source of the confusion, it is argued, could be found, first, in the definitions used for the four positions of young earth creationism, theistic evolution, atheistic evolution and intelligent design. Second, a failure to define the key terms "evolution" and "science," used in some of the survey questions, resulted in responses that were difficult to interpret.

    Full Text Available O interesse pela preservação dos recursos naturais e a busca pelo desenvolvimento sustentável tem despertado interesse de um grande número de pesquisadores visando obter materiais de construção não convencionais. Dentre essas possibilidades, destacam-se os resíduos produzidos pela construção civil e pela indústria de beneficiamento de granito, em virtude do volume gerado e os impactos ambientais do seu descarte inadequado. Este trabalho tem como objetivo estudar a durabilidade das argamassas alternativas incorporadas com resíduos de construção civil e da serragem do granito. Para quantificar a durabilidade dos materiais estudados, foram realizados ensaios de envelhecimento natural e ensaios de envelhecimento acelerado através de ciclos de molhagem e secagem, visando simular condições de utilização e avaliar sua degradação. Nos estudos da durabilidade foram utilizados traços de argamassas para alvenaria de elevação, com percentagens de substituição, em peso, da cal por resíduo de 30% e 50%. Os resultados para o envelhecimento natural evidenciaram o comprometimento da durabilidade do material após 60 dias com redução no comportamento mecânico, sendo os melhores resultados para os corpos-de-prova com 30% e 50% de resíduo de construção. No envelhecimento acelerado, para os tratamentos adotados, os resultados evidenciaram a ação da formação de silicoaluminatos de cálcio e potássio que favoreceram um aumento do comportamento mecânico e, além disso, não foi observado o comprometimento da sua durabilidade.The preservation of natural resources and search for sustainable development are increase in interest by the researchers with the aim to obtain knowledge of non conventional materials.

    The effects of carbon particles and bacterial endotoxins on immunological recovery after irradiation were compared in relation to the radioprotective effects of the agents. When mice were injected with 10 mg of carbon particles (sufficient to protect the animals from radiation-induced death) 24 hrs prior to the administration of sheep red blood cells, the recovery of their immune response to the antigen was not significantly affected. Administration of 1 mg of carbon particles caused a slight enhancement of immune response. Previous treatment of animals with endotoxin resulted in a significant suppression of the immune response regardless of irradiation, the degree of suppression depending on the dose given. These results strongly suggest that the radioprotective effect of carbon- or endotoxin-treatment is attributable to the apparent RES-blockade and to the enhancement of hemopoietic recovery rather than to the enhancement of immunological recovery after irradiation.

    Full Text Available A fermentação em estado semissólido executa um papel importante no aproveitamento de resíduos sólidos, devido à síntese de diferentes compostos, cujo grande interesse seja voltado para segmentos industriais. Objetivou-se estudar o processo de fermentação semissólida do resíduo de abacaxi, utilizando a levedura Saccharomyces cerevisiae, com 10% de inoculo e avaliando o efeito da concentração inicial da levedura, assim como o tempo de fermentação sobre o teor proteico. O processo foi acondicionado em estufa de circulação de ar forçada a 55 °C, durante 48 horas, sendo feita pesagens nos intervalos de 0, 14, 18, 24, 38, 42 e 48 h e realizadas analises físico-químicas e granulométrica. Mediante os resultados, observou-se uma diminuição da umidade com o passar do tempo chegando a atingir 0,91% ao final do estudo, já o teor proteico, aumentou consideravelmente, com proteína bruta de 14% para 20,56%, após 48 h, o teor de sólidos solúveis totais apresentou um declínio possivelmente devido o consumo de carboidratos pela levedura. Foi realizada a análise granulométrica do resíduo, onde se observou que cerca de 80% das partículas apresentaram diâmetro maior que 2,4 milímetros. Através da fermentação semissólida dos resíduos de abacaxi foi possível elevar o teor proteico e aumentar a concentração de nutrientes, transformando um rejeito em um possível produto para destino humano ou animal com alto valor agregado.Protein enrichment of pineapple residue by semisolid fermentationAbstract: The fermentation in state semissólido executes an important paper in the use of solid residues, due to the synthesis of different compounds, which great interest is turned for industrial segments.

    Most of the world activity on research, development and control of polymer durability is still based on empirical techniques developed in the early ages of polymer uses. Those techniques should be critically analysed considering the state of the art in the fundamental understanding of these complex phenomena. A more rational approach is described, especially to predict the lifetime of polymeric materials in environmental conditions. That approach is based on the recognition of the chemical evolution mechanisms. Les activités de recherche, développement et contrôle de durabilité des matériaux polymères sont encore, pour une part très importante, basées sur l'emploi de techniques empiriques dont les principes ont été énoncés dès le début de l'exploitation de ces matériaux. Une analyse critique de ces méthodes s'impose aujourd'hui en tenant compte de l'avancement des connaissances. Une approche plus rationnelle est décrite, approche basée sur la reconnaissance des mécanismes d'évolution chimique. A titre d'exemple, le mécanisme d'évolution du PVC sous contraintes conjuguées de l'UV, de la chaleur et de l'oxygène, est décrit. Des études récentes de photooxydation de polymères conducteurs au sein de polyéthylène sont également succinctement rapportées.

    One major element of EU's external energy policy is expanding its energy norms and regulations to neighbourhood countries and beyond to achieve its energy policy priorities - safe, secure, affordable and sustainable energy supply. The importance of external energy policy has been acknowledged in the European Union's 2007 'energy package', and Second Strategic Energy Review and the European Commission's Communication on security of energy supply and international cooperation. The EU Renewable Energy Directive provides another element to crossborder cooperation by allowing Member States to fulfil their 2020 renewable energy (RES) targets by implementing joint projects in third countries. Even though the Member States' national renewable energy action plans (NREAPs) to reach their RES targets do not indicate any significant use of this mechanism, the RES Directive acknowledges the importance of renewable energy as part of external energy policy. This report aims at presenting the political framework between the EU and the BETTER project target regions (North Africa, Western Balkans and Turkey) with regards to (renewable) energy and the relevant initiatives and the projects to set the scene for RES joint projects as defined in Article 9 of the RES Directive. The main objectives of this study report are (1) to review energy treaties, agreements, and partnerships to assess their relevance to cooperation mechanism with Third countries; and (2) to analyse the relevance of the recent projects and initiatives to BETTER project and improve and trigger the communication and synergies between BETTER project partners and the relevant projects.

    Full Text Available RESUMO - Os resíduos quando disposto de forma incorreta, sem qualquer tratamento, pode poluir o solo, alterando suas características físicas, químicas e biológicas, se tornando também em um problema de ordem estética e uma ameaça à saúde pública. A destinação inadequada dos resíduos sólidos proveniente das diversas atividades humanas é, atualmente, um dos significativos problemas enfrentado pela administração pública no Brasil e em países em desenvolvimento. Este trabalho tem por objetivo diagnosticar o atual processo de gerenciamento dos resíduos sólidos urbanos realizados no município de Pombal – PB, e propor o gerenciamento dos mesmos de maneira mais adequada diante das condições locais. O método de diagnosticar fundamentou-se num levantamento bibliográfico, entrevista ao órgão competente e a aplicação de questionários a população, em todos os bairros do município. Com o resultado deste estudo foi perceptível que a maioria da população necessita ser informada sobre as questões ambientais, para que desta forma gerencie adequadamente seus resíduos. O poder público municipal já está tomando algumas providencias para diminuir os impactos gerados pela falta de um correto gerenciamento dos seus resíduos, mas alguns pontos ainda precisam ser levados em consideração, como trabalhar principalmente a conscientização da população.Palavras chave: Destino final, Conscientização, Poder publico. 

  1. The Rock Engineering System (RES) applied to landslide susceptibility zonation of the northeastern flank of Etna: methodological approach and results

    2015-04-01

    Ground deformations in the northeastern flank of Etna are well known. Despite only a few landslide events have been documented, these have significantly involved and damaged lifelines and buildings. These events are mainly related to the activity of the volcano-tectonic structures and associated seismicity, as in the case of the 2002 reactivation of the Presa landslide during an increased activity of the Pernicana fault system. In order to highlight the areal distribution of potentially unstable slopes based on a detailed, site-specific study of the factors responsible for landslide, and to ultimately contribute to risk management, a landslide susceptibility analysis of the northeastern flank of Etna in the Pernicana area was carried out, and a susceptibility map at 1:10.000 scale was produced, extending over an area of 168 km2. Different methods are proposed in the literature to obtain the regional distribution of potentially unstable slopes, depending on the problem scale, the slope dynamic evolution in the geological context, and the availability of data. Among semi-quantitative approaches, the present research combines the Rock Engineering System (RES) methodology with parameter zonation mapping in a GIS environment. The RES method represents a structured approach to manage a high number of interacting factors involved in the instability problem. A numerically coded, site-specific interaction matrix (IM) analyzes the cause-effect relationship in these factors, and calculates the degree of interactivity of each parameter, normalized by the overall interactivity of the system (weight factor). In the specific Etna case, the considered parameters are: slope attitude, lithotechnical properties (lithology, structural complexity, soil and rock mass quality), land use, tectonic structures, seismic activity (horizontal acceleration) and hydrogeological conditions (groundwater and drainage). Thematic maps are prepared at 1:10.000 scale for each of these parameters, and

    Full Text Available Les polymères auto-renforcés à cristaux liquides (PARCL sont des matériaux dont les molécules, des polymères organiques, sont susceptibles de s'auto-orienter les unes par rapport aux autres. Cette propriété leur confère des caractéristiques mécaniques proches de celles des acier: pour des poids plus faibles sans qu'il soit nécessaire d'avoir recours à des fibres renforçantes. Il existe deux types de PARCL: ceux pouvant s'orienter en solution, qualifiés de lyotropiques, et ceux pouvant s'orienter à l'état fondu, appelés thermotropiques. Des fibres en poly (p-phénylène térephtalamide PPT, PARCL de type lyotropique, sont disponibles commercialement et connaissent déjà de nombreuses applications. Les PARCL thermotropiques n'existent pas encore sur le marché mais sont porteurs de nombreux espoirs car ils sont susceptibles d'être moulés et donc de prendre les formes les plus diverses, ce qui n'est pas le cas de ceux de type lyotropique. Self-reinforcing liquid-crystal polymers are materials in which the molecules, i. e. organic polymers, are capable of orienting themselves in relation to one another. This property gives them mechanical characteristics close to those of steels yet of much less weight without having to use reinforcing fibers. There are two types of self-reinforcing liquid-crystal polymers: (i those capable of orienting themselves in solution, called Iyotropic, and (ii those capable of orienting themselves in a molten state, called thermotropic. Poly (p-phenylene terephthalamide fibers, self-reinforcing liquid-crystal polymers of the Iyotropic type, are commercially available and have already found numerous applications. Thermotropic self-reinforcing liquid-crystal polymers are not yet on the market but seem to be very promising because they are capable of being molded and hence of taking on a wide variety of shapes, which is not the case of those of the lyotropic type.

    Les travaux de recherches sur la sécurité transfusionnelle en Afrique sub-saharienne sont peu nombreux, souvent limités à des initiatives locales avec des conclusions difficilement représentatives de cette région. Le Groupe de recherches transfusionnelles en Afrique sub-saharienne francophone a été créé en mai 2007 avec pour objectif de développer des stratégies globales d’amélioration de la sécurité transfusionnelle mais adaptables à la situation de chaque pays. Les activités du Groupe à ce jour ont porté essentiellement sur l’obtention de données épidémiologiques et de laboratoire sur la transfusion sanguine et à proposer des stratégies de sécurité transfusionnelle dans le domaine des infections transmissibles par la transfusion. Pour mener à bien ces activités de recherche, le Groupe travaille en étroite collaboration avec les Centres nationaux de transfusion sanguine (CNTS), les Centres régionaux de transfusion sanguine (CRTS), les banques de sang hospitalières (BSH) et les postes de collecte de sang. Pour les 5 premières années, quatre priorités de recherche ont été identifiées: (i) des études descriptives sur les caractéristiques des donneurs de sang et des centres de transfusion; (ii) une estimation du risque résiduel post-transfusionnel des principales infections virales transmissibles par la transfusion; (iii) une analyse des stratégies de sélection médicale des donneurs de sang; et (iv) une description des stratégies de dépistage des ITT et une description du système d’assurance qualité externe existant. Durant cette période, sept projets ont été mis en œuvre au niveau national et publiés et cinq études multicentriques ont été réalisées et publiées. La présente étude rapporte les principales observations et recommandations de ces études. PMID:24360798

    Precipitation is a key forcing variable in hydrological modeling of floods and being able to accurately observe precipitation is extremely important in mitigating flood impacts. The Global Precipitation Measurement (GPM) Mission, launched in Feb 2014 also presents an opportunity for high-quality real-time precipitation data and improved flood warnings. The PERSIANN-CCS developed by the scientists at the Center for Hydrometeorology and Remote Sensing (CHRS) at the University of California, Irvine is one algorithm integrated in the IMERG of PMM/GPM. In this research, the high resolution coupled hydrologic/hydraulic model named HiResFlood-UCI was applied to simulate the historical 2008 Iowa flood in the Cedar River basin. HiResFlood-UCI is a coupling of the NWS's distributed hydrologic model HL-RDHM and the hydraulic model BreZo developed by the Computational Hydraulics Group at the University of California, Irvine. The model was forced with the real-time PERSIANN-CCS and NEXRAD Stage 2 precipitation data. Simulations were evaluated based on 2 criteria: hydrographs within the basin and the areal extent of the flooding. Streamflow hydrographs were compared at 7 USGS gages, and simulated inundation maps were evaluated using USDA AWiFS 56m resolution areal flood imagery. The results show reasonable simulated hydrographs compared to USGS streamflow observations when simulating with PERSIANN-CCS and NEXRAD Stage 2 as forcing inputs. The simulation driven by NEXRAD Stage 2 slightly outperforms the PERSIANN-CCS simulation as the latter marginally underestimated the observed hydrographs. The simulation in both cases shows a good agreement (0.672 and 0.727 CSI for Stage 2 and PERSIANN-CCS simulations respectively) with the AWiFS image over the most impacted area in the Cedar Rapids region. Since the PERSIANN-CCS simulation slightly underestimated the discharge, the probability of detection (0.925) is lower than that of the Stage 2 simulation (0.965). As a trade-off, the false

    2011-01-01

    Previous studies have confirmed that current steering can increase the number of discriminable pitches available to many cochlear implant (CI) users; however, the ability to perceive additional pitches has not been linked to improved speech perception. The primary goals of this study were to determine (1) whether adult CI users can achieve higher levels of spectral cue transmission with a speech processing strategy that implements current steering (Fidelity120) than with a predecessor strategy (HiRes) and, if so, (2) whether the magnitude of improvement can be predicted from individual differences in place-pitch sensitivity. A secondary goal was to determine whether Fidelity120 supports higher levels of speech recognition in noise than HiRes. A within-subjects repeated measures design evaluated speech perception performance with Fidelity120 relative to HiRes in 10 adult CI users. Subjects used the novel strategy (either HiRes or Fidelity120) for 8 wks during the main study; a subset of five subjects used Fidelity120 for three additional months after the main study. Speech perception was assessed for the spectral cues related to vowel F1 frequency, vowel F2 frequency, and consonant place of articulation; overall transmitted information for vowels and consonants; and sentence recognition in noise. Place-pitch sensitivity was measured for electrode pairs in the apical, middle, and basal regions of the implanted array using a psychophysical pitch-ranking task. With one exception, there was no effect of strategy (HiRes versus Fidelity120) on the speech measures tested, either during the main study (N = 10) or after extended use of Fidelity120 (N = 5). The exception was a small but significant advantage for HiRes over Fidelity120 for consonant perception during the main study. Examination of individual subjects' data revealed that 3 of 10 subjects demonstrated improved perception of one or more spectral cues with Fidelity120 relative to HiRes after 8 wks or longer

  8. In Search of the ‘New Informal Legitimacy’ of Médecins Sans Frontières

    Science.gov (United States)

    Calain, Philippe

    2012-01-01

    For medical humanitarian organizations, making their sources of legitimacy explicit is a useful exercise, in response to: misperceptions, concerns over the ‘humanitarian space’, controversies about specific humanitarian actions, challenges about resources allocation and moral suffering among humanitarian workers. This is also a difficult exercise, where normative criteria such as international law or humanitarian principles are often misrepresented as primary sources of legitimacy. This essay first argues for a morally principled definition of humanitarian medicine, based on the selfless intention of individual humanitarian actors. Taking Médecins Sans Frontières (MSF) as a case in point, a common source of moral legitimacy for medical humanitarian organizations is their cosmopolitan appeal to distributive justice and collective responsibility. More informally, their legitimacy is grounded in the rightfulness of specific actions and choices. This implies a constant commitment to publicity and accountability. Legitimacy is also generated by tangible support from the public to individual organizations, by commitments to professional integrity, and by academic alliances to support evidence-based practice and operational research.

    2011-03-01

    Médecins Sans Frontières (MSF) is an independent medical humanitarian organisation working in over 70 countries. It has provided medical assistance for over 35 years to populations vulnerable through conflict, disease and inadequate health systems. Medical ethics define the starting point of the relationship between medical staff and patients. The ethics of humanitarian interventions and of research in conflict settings are much debated. However, less is known about the ethical dilemmas faced by medical humanitarian staff in their daily work. Ethical dilemmas can be intensified in humanitarian contexts by insecure environments, lack of optimum care, language barriers, potentially heightened power discrepancies between care providers and patients, differing cultural values and perceptions of patients, communities and medical staff. Time constraints, stressful conditions and lack of familiarity with ethical frameworks can prevent reflection on these dilemmas, as can frustration that such reflection does not necessarily provide instant solutions. Lack of reflection, however, can be distressing for medical practitioners and can reduce the quality of care. Ethical reflection has a central role in MSF, and the organisation uses ethical frameworks to help with clinical and programmatic decisions as well as in deliberations over operational research. We illustrate and discuss some real ethical dilemmas facing MSF teams. Only by sharing and seeking guidance can MSF and similar actors make more thoughtful and appropriate decisions. Our aim in sharing these cases is to invite discussion and dialogue in the wider medical community working in crisis, conflict or with severe resource limitations.

En assimilant les deux groupes d'"étrangères” (nationales et non nationales, car elle pense que le même type d’accueil doit être fourni à toutes, Tristan préconise l’aide à la voisine nécessiteuse, voisine qui est à la fois un sujet national ou un sujet en transit, une femme sans-papiers ou une réfugiée.

    Full Text Available A geração dos resíduos sólidos urbanos (RSU no Brasil vem aumentando ao longo do tempo, com alterações na qualidade do resíduo, o que levanta discussões a respeito do gerenciamento e da importância em se destinar estes resíduos adequadamente. Atualmente as questões que envolvem a gestão dos RSU têm enfoque central no cumprimento de políticas públicas. A partir da implementação efetiva da Política Nacional de Resíduos Sólidos (PNRS - lei nº 12.305/2010 é que se esperam mudanças no panorama dos resíduos sólidos no Brasil. Por conta disso, este trabalho faz um levantamento bibliográfico que tem como objetivo abordar aspectos sobre os RSU no Brasil, considerando aqueles esperados para acontecer no setor público após a implementação da PNRS. Os dados apresentados e discutidos permitiram entender a evolução da gestão dos RSU no Brasil e alguns desafios para o cumprimento das determinações da PNRS, como, por exemplo, a expansão da coleta e tratamento dos RSU, o papel mais ativo da sociedade nos processos que envolvem a separação dos resíduos e a dificuldade da erradicação de lixões e sua substituição por aterros sanitários. Em geral, apesar de terem ocorrido melhoras no gerenciamento dos RSU, estas não foram suficientes para que as mudanças propostas pela PNRS fossem cumpridas e para que se estabeleça uma gestão integrada de RSU mais eficaz e sustentável tanto ao meio ambiente quanto à sociedade, denotando a emergência de soluções estruturais no setor de gerenciamentos dos RSU no Brasil.

    Full Text Available A taxa de mineralização do nitrogênio (N varia de um resíduo orgânico para outro, evidenciando-se dependente da sua composição química e interação do material orgânico com o solo. Este estudo foi realizado com o objetivo de avaliar a dinâmica de mineralização de N de resíduos orgânicos incubados em Latossolos. O experimento foi conduzido no período de julho de 2007 a abril de 2008, sendo incubadas amostras de estercos, lodos, compostos, substrato e turfa em areia lavada, Latossolo Vermelho-Amarelo (LVA e Latossolo Vermelho distroférrico (LVdf, com 240 e 670 g kg-1 de argila, respectivamente. O N mineralizado foi avaliado medindo-se os teores de N-NH4+ e N-NO3- em lixiviados coletados aos 15, 30, 45, 60, 75, 90, 120, 150, 180, 210, 240 e 270 dias de incubação. A mineralização de N ocorreu a maiores taxas nos períodos iniciais de incubação. O N mineralizado (33 a 199,2 mg kg-1 após 270 dias de incubação é regulado pelos teores de N total e de carbono solúvel em água dos resíduos orgânicos. Independentemente do meio utilizado para incubação, os estercos de galinha e de codorna propiciaram os maiores teores de N mineralizado nos Latossolos. À exceção dos estercos de galinha e codorna, há imobilização líquida de N no LVA; mineralização líquida de N é verificada no LVdf, para todos os resíduos orgânicos. Em relação às formas de N disponibilizadas pelos resíduos, predomina o N-nitrato, sendo a proporção N-nítrico/N-amoniacal dependente da mistura solo-resíduo estudada.

É exposta a legislação brasileira pertinente ao gerenciamento dos resíduos sólidos na construção, e mais especificamente as resoluções CONAMA 307/02 e 431/11, em que o resíduo de gesso passou a ter uma reclassificação quanto a sua destinação. Assim, esse passou a ser considerado um material passível de reutilização e reciclagem. Dessa forma, o objetivo do trabalho foi investigar a viabilidade técnica de aproveitamento de resíduos de gesso como matéria-prima para materiais de construção, no caso, pela incorporação deste em telhas. Assim, é feita uma descrição dos tipos de telhas, suas características e métodos de fabricação, como também a exposição de dois tipos de telhas recicladas. É descrito também o albedo, associado com o benefício de telhados brancos na redução da temperatura dentro das edificações nos dias de maior calor. Foi feita uma lista com as formas e cobrimentos possíveis para a adaptação do gesso na telha, e a partir de características favoráveis às telhas foi escolhido o modelo a ser detalhado, a partir de uma matriz avaliativa. O modelo escolhido foi o Colonial Gigante, com capa polimérica feita de resíduo de PET (politereftaleno de etileno envolvendo o resíduo de gesso. Um modelo 3D foi desenvolvido, e a telha foi nomeada de Telha GePET. Foram definidas em laboratório a umidade e a massa específica aparente e unitária do resíduo de gesso. Diversas características da telha foram descritas, como suas dimensões, massa, fonte de matéria-prima, produção, instalação no telhado, manutenção e durabilidade, o descarte após sua vida útil, o albedo, o isolamento térmico e o valor da telha. Concluiu-se que é possível a fabricação de uma telha com resíduos de gesso, juntamente com o resíduo de PET, tornando-a um produto mais sustentável e 100% reciclável.

Divers moyens de lutte antisalissure ont été envisagés parmi lesquels les peintures marines antisalissures occupent une place de choix. Ces peintures contiennent, en général, un composé métallique toxique envers les organismes marins d'origine animale ou végétale et différents mécanismes d'action ont été proposés. Les dérivés organostanniques sont des agents biocides très efficaces et lorsqu'ils sont liés chimiquement sur un polymère, en particulier sous forme de greffons, on obtient un contrôle amélioré de leur lixiviation dans la phase aqueuse et par conséquent la durée de vie du revêtement antisalissure est prolongée. La synthèse de polymères comportant un cation organostannique toxique peut être effectuée, soit par la polymérisation ou la copolymérisation de monomères insaturés organostanniques, soit par la réaction chimique de composés organostanniques avec un substrat polymère comportant des groupes fonctionnels appropriés. Les avantages et les inconvénients de diverses formulations de peintures à base de dérivés organostanniques sont discutés. Marine fouling deposits on submerged structures are influenced by several factors and bring about harmful consequences, especially with regard to offshore oil-production platform structures and for the energy consumption required for ship propulsion.

    2013-12-01

    Full Text Available Neste trabalho são discutidos os principais aspectos relacionados à geração de resíduos da construção civil, sob ponto de vista de sustentabilidade das edificações. Esse conceito exige, das novas construções, a adoção de projetos criativos e eficientes, com soluções adequadas para as diversas fases de vida da obra, incluindo a previsão do reaproveitamento e descarte de materiais ao fim de sua vida útil. Um dos problemas atuais da gestão de resíduos da construção civil é que a segregação dos materiais por classe, visando à sua posterior reciclagem ou descarte, só acontece na cidade do Rio de Janeiro em grandes obras com canteiros instalados, embora mais da metade da quantidade produzida seja proveniente de pequenas obras com resíduos descartados em caçambas de rua ou simplesmente lançados em vias públicas ou terrenos baldios. É sugerido um plano de gestão circular, especialmente voltado para os pequenos geradores, com obrigatoriedade de segregação dos materiais, instalação de pontos de recolhimento pelos bairros da cidade e implantação de centros de tratamento de resíduos da construção civil, operados por associações de catadores, com objetivo de produção de materiais reciclados. O sucesso da proposta depende da efetiva participação de todos os agentes envolvidos no processo, como o poder público, proprietários, empresas e demais profissionais da indústria da construção civil.

Foram determinadas mensalmente as variáveis diâmetro do coleto, altura da haste, número de folhas e taxa de crescimento relativo e, após 180 dias da repicagem, os valores SPAD (Soil and Plant Analysis Development, dinâmica da assimilação de CO2, da transpiração e da condutividade estomática. O resíduo de mineração de areia puro como substrato não proporcionou mudas de qualidade, visto que esse material apresenta alta densidade e baixa granulometria. Seu uso pode ser indicado como um dos componentes de substratos, pois as plantas que cresceram nas misturas de resíduo e casca de arroz carbonizada apresentaram resultados semelhantes ao do considerado padrão.

    Full Text Available Les ressources forestières constituent un capital naturel pour l’approvisionnement des populations locales, en bois, en plantes aromatiques et médicinales et en parcours pour le pâturage. Ces multiples usages ont conduit ces populations à mettre en place une gestion communautaire et très ancienne de ces ressources. Depuis 2002, l’administration des Eaux et Forêts a mis en place une politique forestière basée sur une stratégie de gestion participative. Nous avons étudié les formes de gestion communautaire et par l’administration des ressources forestières dans quatre communes rurales du Parc National d’Ifrane. L’administration organise une mise en défens, fondée sur l’implication et la responsabilisation des populations usagères, organisée en associations sylvo-pastorales ou en coopératives forestières, à travers une incitation financière sous forme de compensation. Ce mécanisme a permis d’obtenir un certain nombre d’acquis : conscientisation des populations vis-à-vis de la mise en défens, investissement des sommes de la compensation dans des projets de développement local, etc. Cependant, ce mécanisme présente certaines fragilités, notamment un risque de non durabilité des mises en défens (du fait que celles-ci ne sont financées que par le budget de l’Etat et un contrôle social plus faible dans les nouvelles associations qui n’ont pas la même légitimité pour prendre des décisions au nom du collectif que les anciennes jmaa.

    Full Text Available O Brasil está entre os 10 países que mais desperdiçam alimentos no mundo. Aproximadamente 35% da produção agrícola nacional tornam-se lixo, que representa quantitativamente valores acima de 10 milhões de toneladas de alimentos, e caso estes não sejam considerados a alguma finalidade, podem comprometer o meio ambiente.Mediante o grande desperdício de alimentos ocorridos na região do Cariri, dentre eles os de maior destaque são as frutas e hortaliças, com consequente geração de resíduos originários das etapas de produção, distribuição e comercialização. Ressalta-se a importância de conhecimentos acerca da adoção de práticas em respeito ao ambiente, portanto, o presente estudo teve como objetivo analisar o gerenciamento de resíduos provenientes de determinadas empresas do setor hortifrúti da região do Cariri. Diante dos resultados encontrados neste estudo observou-se que todas as empresas geram resíduos e que estão sendo capazes de utilizá-los atribuindo aos mesmos finalidades como alimentação animal e compostagem, o que nos garante que tais empresas, preconizam condutas de gerenciamento de resíduos adequadas, adotando uma postura ética de comprometimento com o social e o meio ambiente.Palavras-chave: desperdício, compostagem, meio ambiente.

    The accurate representation of aerosols in climate models requires direct ambient measurement of the size- and composition-dependent particle production fluxes. Here we present the design, testing, and analysis of data collected through the first instrument capable of measuring hygroscopicity-based, size-resolved particle fluxes using a continuous-flow Hygroscopicity-Resolved Relaxed Eddy Accumulation (Hy-Res REA) technique. The different components of the instrument were extensively tested inside the US Environmental Protection Agency's Aerosol Test Facility for sea-salt and ammoniums sulfate particle fluxes. The new REA system design does not require particle accumulation, therefore avoids the diffusional wall losses associated with long residence times of particles inside the air collectors of the traditional REA devices. The Hy-Res REA system used in this study includes a 3-D sonic anemometer, two fast-response solenoid valves, two Condensation Particle Counters (CPCs), a Scanning Mobility Particle Sizer (SMPS), and a Hygroscopicity Tandem Differential Mobility Analyzer (HTDMA). A linear relationship was found between the sea-salt particle fluxes measured by eddy covariance and REA techniques, with comparable theoretical (0.34) and measured (0.39) proportionality constants. The sea-salt particle detection limit of the Hy-Res REA flux system is estimated to be 6x105 m-2s-1. For the conditions of ammonium sulfate and sea-salt particles of comparable source strength and location, the continuous-flow Hy-Res REA instrument was able to achieve better than 90% accuracy of measuring the sea-salt particle fluxes. In principle, the instrument can be applied to measure fluxes of particles of variable size and distinct hygroscopic properties (i.e., mineral dust, black carbon, etc.).

    Full Text Available It also addresses the debate about the revitalization of the res judicata in the civil suit of the individual cognitive tutelage when the sentence goes against constitutional norms or principles. It highlights that only the existent sentences, which lead to res judicata unconstitutional or unjust, may be relativized. It sees the principle of proportionality as a method or criterion adequate to solve the conflict of values that arises when the law enforcer is faced with an unfair or unconstitutional sentence. Only the consideration upon values, in a true case, is able to determine whether the res judicata must be kept or not in the juridical order. To relativize the res judicata unconstitutional a de-constitutive action is proposed, with the same characteristics of a rescinding action, but not subject to terms of duration.Trata da polêmica sobre a relativização da coisa julgada no processo civil de tutela cognitiva individual, quando a sentença afronta normas ou princípios constitucionais. Enfoca que somente as sentenças existentes, que produzem coisa julgada inconstitucional ou injusta, podem ser relativizadas. Aponta o princípio da proporcionalidade como método ou critério adequado para resolver o conflito de valores. Somente a ponderação de valores, no caso concreto, é capaz de determinar se a coisa julgada deve ser mantida ou não na ordem jurídica. Para relativizar a coisa julgada inconstitucional propõe o cabimento de uma ação desconstitutiva, com as mesmas características da ação rescisória, mas não sujeita a prazo.

  4. Experimental determination of the hydrothermal solubility of ReS2 and the Re–ReO2 buffer assemblage and transport of rhenium under supercritical conditions

    Wood Scott A

    2002-01-01

    Full Text Available To understand the aqueous species important for transport of rhenium under supercritical conditions, we conducted a series of solubility experiments on the Re–ReO2 buffer assemblage and ReS2. In these experiments, pH was buffered by the K–feldspar–muscovite–quartz assemblage; in sulfur-free systems was buffered by the Re–ReO2 assemblage; and and in sulfur-containing systems were buffered by the magnetite–pyrite–pyrrhotite assemblage. Our experimental studies indicate that the species ReCl40 is dominant at 400°C in slightly acidic to near-neutral, and chloride-rich (total chloride concentrations ranging from 0.5 to 1.0 M environments, and ReCl3+ may predominate at 500°C in a solution with total chloride concentrations ranging from 0.5 to 1.5 M. The results also demonstrate that the solubility of ReS2 is about two orders of magnitude less than that of ReO2. This finding not only suggests that ReS2 (or a ReS2 component in molybdenite is the solubility-controlling phase in sulfur-containing, reducing environments but also implies that a mixing process involving an oxidized, rhenium-containing solution and a solution with reduced sulfur is one of the most effective mechanisms for deposition of rhenium. In analogy with Re, TcS2 may be the stable Tc-bearing phase in deep geological repositories of radioactive wastes.

    Full Text Available Este trabalho teve como objetivo avaliar a qualidade de chapas aglomeradas fabricadas com resíduos da madeira de Eucalyptus saligna, resultantes da picagem das toras para a confecção de cavacos utilizados na produção de celulose. As chapas foram produzidas com dois tipos de resíduos, palitos e serragem, sendo utilizados puros. O adesivo usado foi à base de uréia-formaldeído em proporções de 4; 8 e 12%, com base na massa seca das partículas, e as densidades nominais das chapas foram de 0,55; 0,65 e 0,75 g/cm3. Foram avaliadas propriedades de flexão estática, ligação interna, arrancamento de parafusos, absorção d'água e inchamento em espessura. Os valores obtidos das propriedades de flexão estática, ligação interna e arrancamento de parafusos aumentaram com a densidade da chapa, assim como com o teor de adesivo, independentemente do tipo de resíduo. No caso da absorção d'água, os valores aumentaram com a redução da densidade, tanto para chapas produzidas com partículas tipo palitos como para serragem. Para inchamento em espessura, os valores aumentaram com a diminuição do teor de adesivo, sem considerar o do tipo de resíduo utilizado. Os resultados permitem concluir que, usando-se tanto partículas tipo palitos quanto serragem com maiores percentagens de adesivo e maiores densidades, podem ser produzidas chapas com qualidade satisfatória.

    Many countries ravaged by conflict have substantial morbidity and mortality attributed to HIV/AIDS yet HIV treatment is uncommonly available. Universal access to HIV care cannot be achieved unless the needs of populations in conflict-affected areas are addressed. From 2003 Médecins Sans Frontières introduced HIV care, including antiretroviral therapy, into 24 programmes in conflict or post-conflict settings, mainly in sub-Saharan Africa. HIV care and treatment activities were usually integrated within other medical activities. Project data collected in the Fuchia software system were analysed and outcomes compared with ART-LINC data. Programme reports and other relevant documents and interviews with local and headquarters staff were used to develop lessons learned. In the 22 programmes where ART was initiated, more than 10,500 people were diagnosed with HIV and received medical care, and 4555 commenced antiretroviral therapy, including 348 children. Complete data were available for adults in 20 programmes (n = 4145). At analysis, 2645 (64%) remained on ART, 422 (10%) had died, 466 (11%) lost to follow-up, 417 (10%) transferred to another programme, and 195 (5%) had an unclear outcome. Median 12-month mortality and loss to follow-up were 9% and 11% respectively, and median 6-month CD4 gain was 129 cells/mm 3.Patient outcomes on treatment were comparable to those in stable resource-limited settings, and individuals and communities obtained significant benefits from access to HIV treatment. Programme disruption through instability was uncommon with only one program experiencing interruption to services, and programs were adapted to allow for disruption and population movements. Integration of HIV activities strengthened other health activities contributing to health benefits for all victims of conflict and increasing the potential sustainability for implemented activities.

    Médecins Sans Frontières (MSF) is a humanitarian organization that performs emergency and elective surgical services in both conflict and non-conflict settings in over 70 countries. In 2006 MSF surgeons departed on approximately 125 missions, and over 64,000 surgical interventions were carried out in some 20 countries worldwide. Historically, the majority of MSF surgical projects began in response to conflicts or natural disasters. During an emergency response, MSF has resources to set up major operating facilities within 48 h in remote areas. One of MSF strengths is its supply chain. Large pre-packaged surgical kits, veritable "operating theatres to go," can be readied in enormous crates and quickly loaded onto planes. In more stable contexts, MSF has also strengthened the delivery of surgical services within a country's public health system. The MSF surgeon is the generalist in the broadest sense and performs vascular, obstetrical, orthopaedic, and other specialized surgical procedures. The organization aims to provide surgical services only temporarily. When there is a decrease in acute needs a program will be closed, or more importantly, turned over to the Ministry of Health or another non-governmental organization. The long-term solution to alleviating the global burden of surgical disease lies in building up a domestic surgical workforce capable of responding to the major causes of surgery-related morbidity and mortality. However, given that even countries with the resources of the United States suffer from an insufficiency of surgeons, the need for international emergency organizations to provide surgical assistance during acute emergencies will remain for the foreseeable future.

    Full Text Available L'analyse des messages publicitaires insérés dans la presse écrite et télévisée par les institutions financières de 1960 à 1991 permet d'approcher l'influence socio-culturelle de ce secteur de l'économie sur les modes de vie des strates aisées et moyennes de la population équatorienne à partir de l'exemple quiténien. Si le message a vu son support évoluer depuis trois décennies (dessin dans les années soixante, photographie durant les années soixante- dix puis images de synthèse au cours des années quatre- vingt, son image projetée se caractérise par une relative continuité thématique. Toutefois, il semble que les campagnes publicitaires financières délaissent progressivement les éléments importés et intègrent (« récupèrent » ? des caractères régionaux ou nationaux. Enfin, si dans les années soixante le système financier avait recours à un langage spécifique, il s'oriente aujourd'hui vers l'utilisation de symboles et d'éléments écrits ou visuels qui sont tout à fait intégrés à la mondialisation de la communication.

    2004-01-01

    The polarization sensitive behaviour of the band-edge transitions in ReS 2 and ReSe 2 layered compounds was studied using polarized-transmission and polarized-thermoreflectance (PTR) measurements with polarization angles from θ = 0 deg. (Evector parallel b-axis) to θ = 90 deg. (Evector perpendicular b-axis) at 300 K. The polarization dependence of the polarized energy gaps of ReS 2 and ReSe 2 shows a sinusoidal-like variation with respect to the angular change of the linearly polarized light. The angular dependences of the polarized energy gaps of ReS 2 and ReSe 2 were evaluated. The polarization sensitive behaviour of the band-edge excitons in rhenium disulfide and diselenide was characterized using angular dependent PTR measurements from θ = 0 deg. to 90 deg. The polarized transition intensities of the band-edge excitons (E 1 ex and E 2 ex ) of ReX 2 (X = S, Se) demonstrate a sinusoidal variation with respect to the angular change of the linearly polarized light. The angular dependence of the polarized transition probabilities of E 1 ex and E 2 ex is analysed. The polarization sensitive behaviours of ReX 2 (X = S, Se) layers are discussed

    The transition-metal dichalcogenides ReX sub 2 (X = S or Se) and TcS sub 2 with a d sup 3 electron configuration have distorted CdCl sub 2 and Cd(OH) sub 2 structures, respectively, with the Re(Tc) atoms in each layer forming parallelogram-shaped connected clusters (diamond chain). Ab-initio band-structure calculations were performed for ReX sub 2 and TcS sub 2 , and the hypothetical undistorted 1T-TcS sub 2 and 3R-ReX sub 2 structures. The calculations show that ReS sub 2 , ReSe sub 2 and TcS sub 2 are semiconductors with energy gaps of about 1.0 eV, 0.5 eV and 0.7 eV, respectively, while for the undistorted structures the Fermi level is in the partly filled band of d sub x sub sup 2 sub - sub y sub sup 2 and d sub x sub y orbitals of the t sub 2 sub g manifold. X-ray photoemission spectra for the core levels and valence band of ReSe sub 2 and ReS sub 2 are presented. The valence x-ray photoemission spectra showed that ReS sub 2 is a p-type semiconductor with an energy gap of about 1.5 eV, while ReSe sub 2 i...

    Full Text Available O controle da entrada de água de chuva no interior do aterro de resíduos sólidos urbanos durante sua construção e após seu fechamento é crucial para manter o controle da geração de lixiviado. Este fator pode contribuir para a elevação de gastos com tratamento e monitoramento e para a instabilidade mecânica do aterro. Por esta razão, o sistema de cobertura final de um aterro de resíduos sólidos urbanos é decisivo ao controle da entrada de água no mesmo. Na maioria dos casos, o sistema de cobertura final é composto por solo compactado. Frequentemente, um solo adequado para a cobertura não é encontrado nos arredores do aterro; portanto, recursos têm que ser despendidos para o transporte do mesmo até o devido local. Uma alternativa seria a utilização de uma barreira capilar construída com resíduos pré-tratados mecânica e biologicamente. No entanto, o uso deste material para esta construção ainda não foi bem estudado, e as diversas variáveis envolvidas no funcionamento de uma barreira capilar construída com resíduos sólidos pré-tratados mecânica e biologicamente são desconhecidas. O objetivo deste trabalho foi analisar os parâmetros envolvidos no funcionamento de uma barreira capilar construída exclusivamente de resíduos sólidos urbanos pré-tratados mecânica e biologicamente. Observou-se que este utilizado como material de uma barreira capilar pode funcionar de maneira equivalente àquela construída com solo, sendo boa a sua capacidade de retenção da água de chuva.

    Full Text Available O objetivo deste artigo é analisar aspectos normativos para o gerenciamento de resíduos de medicamentos numa região do Brasil e descrever os elementos fundamentais para a sua prática, valendo-se de exemplos bem-sucedidos e das principais políticas nacionais que norteiam o tema. Este trabalho analisa a legislação federal e da Região Sudeste em relação ao descarte de resíduos de medicamentos visando verificar em que medida as proposições legais contribuem para um gerenciamento eficaz de resíduos. São também avaliadas experiências bem-sucedidas de descarte de medicamentos vencidos. Observou-se que nas legislações existentes há lacunas. Elas estabelecem responsabilidades para os fabricantes, distribuidores e serviços de saúde, mas não instituem ações para o descarte de medicamentos pelos usuários, nem determinam o tipo de tratamento em função das diferentes classes de medicamentos, o que pode prejudicar o correto gerenciamento desses resíduos. Quanto às experiências bem-sucedidas, observou-se que houve articulação entre diferentes atores sociais e esferas de governo para o descarte de medicamentos vencidos. O artigo finaliza com propostas de ações em relação às duas lacunas identificadas. Quanto à conscientização dos usuários, é sugerida ação articulada com programas que têm inserção comunitária como Saúde da Família. A respeito do tratamento específico para classes farmacêuticas, propõe-se ação conjunta universidade- empresa-governo na pesquisa desses tratamentos. Por fim, sugere-se revisão das normas relacionadas aos resíduos de medicamentos.

    Full Text Available A utilização de resíduos e subprodutos industriais na construção civil apresenta-se como uma alternativa efetiva para diminuição do impacto ambiental deste setor. O presente trabalho tem como principal objetivo avaliar a viabilidade do emprego de solo-cimento e resíduo de beneficiamento de pedras preciosas em estacas escavadas (SCR para utilização em habitação unifamiliar. Inicialmente foi definida uma mistura ótima com os materiais que constituiriam as estacas. A mistura que melhor atendeu as características de resistência e trabalhabilidade foi àquela composta por 50% de resíduo de beneficiamento de pedras preciosas e 50% de solo, com 10% de teor de cimento Portland, em relação a massa seca dos materiais. Para os ensaios de campo foram executadas três estacas escavadas de 0,23m de diâmetro e 3 metros de profundidade. Os resultados obtidos através das provas de carga estática foram comparados a resultados de estacas escavadas com mesmas características geométricas e compostas por concreto convencional. O estudo concluiu que o emprego da mistura de solo-cimento e resíduo de beneficiamento de pedras preciosas em estacas escavadas moldadas in loco é tecnicamente viável, uma vez que apresentam capacidade de carga semelhante às executadas com concreto convencional. Além disso, a partir da análise de custos, onde se comparou o valor de execução para estacas de concreto e estacas de solo-cimento e resíduo, verificou-se que o custo final de uma estaca escavada produzida com a mistura proposta apresenta uma economia de 38%, se comparado ao custo final de uma estaca escavada composta por concreto convencional.

Esta pesquisa objetiva avaliar a utilização de resíduos da construção civil, oriundos de demolição, como agente pozolânico na fabricação de blocos solo-cal. As matérias primas convencionais e alternativas (resíduos foram caracterizados por meio dos seguintes ensaios: massa especifica real, área específica, análise granulométrica por peneiramento e por difração á laser,limites de liquidez e plasticidade, análise química e difração de raios X. Para os ensaios tecnológicos foram confeccionados corpos de prova solo-cal no traço 1:10 em peso, com substituição da cal por resíduos nas seguintes proporções: 0, 10, 20, 25, 30, 40, 50 e 75%. Os corpos de prova foram curados por períodos de 28, 60 e 90 dias, em câmara úmida com 100% de umidade relativa, em seguida determinada sua resistência à compressão simples e absorção de água. Com os melhores resultados de resistência a compressão simples, foram moldados blocos solo-cal e solo-cal-resíduo. Os resultados obtidos com os blocos solo-cal incorporados com resíduo evidenciaram valores dentro das especificações das normas da ABNT, apontando que existe viabilidade técnica no aproveitamento de resíduos de demolição para uso na fabricação de blocos solo-cal sem função estrutural.New techniques have been developed with the aim of encouraging sustainable development and try to minimize the environmental degradation caused by indiscriminate extraction of natural resources and the constant generation of building waste.

    Full Text Available O experimento foi conduzido no Centro Nacional de Gado de Corte da Empresa Brasileira de Pesquisa Agropecuária (Embrapa Gado de Corte. Foram avaliadas as características morfogênicas de folhas e perfilhos, acúmulo de matéria seca verde e índices de crescimento do capim-tanzânia em dois resíduos forrageiros pós-pastejo (Resíduo alto -- RA 3,6 t de MS/ha e Resíduo baixo -- RB 2,3 t de MS/ha, até os 35 dias após o pastejo. O delineamento experimental foi em blocos casualizados completos com os tratamentos no esquema de parcelas subdivididas com três repetições. Para a dinâmica de perfilhamento houve diferença entre resíduos somente no aparecimento de novos perfilhos basilares. A taxa de aparecimento de novos perfilhos, tanto basilares quanto aéreos, decresceu linearmente com os dias de rebrotação após o pastejo. As taxas de alongamento e senescência de folhas não diferiram entre resíduos e tipos de perfilho. Em contrapartida, a duração de alongamento foliar foi menor no resíduo baixo e no perfilho novo, porém produzindo folhas com menor comprimento final. Houve interação entre resíduo e tipo de perfilho para a taxa de aparecimento de folhas, com maiores valores para o resíduo baixo no perfilho novo e remanescente. O acúmulo de matéria seca verde não diferiu entre resíduos, sendo, em média, 61,4 e 47,9 kg/ha.dia, nos resíduos baixo e alto, respectivamente. A taxa de crescimento relativo e o índice de área foliar não apresentaram diferenças entre resíduos forrageiros, porém apresentaram comportamento inverso em função dos dias após o pastejo.

    Full Text Available Les premiers combats de la classe ouvrière se sont portés sur la demande d’une journée de repos, qui par tradition chrétienne a été fixée le dimanche en 1906. Quatre journées de congé à caractère chrétien ont en outre été retenues par le législateur. L’exercice du culte est donc concrètement garanti pour les chrétiens. Avec l’arrivée sur le territoire de la République  de populations de confessions variées, cette organisation du travail apparaît inégalitaire, voire de nature à porter atteinte à la liberté religieuse. Il a été proposé de reconnaître les jours de prières d’autres confessions. Pour l’instant, le législateur n’a pas adopté ces propositions. Mais la question reste posée. Or, la jurisprudence des tribunaux judiciaires et administratifs admet le droit de prier des fidèles des cultes minoritaires, ils peuvent prétendre à un congé lors des fêtes de leur religion dans la mesure où cela n’occasionne pas de perturbation. La consécration de cette jurisprudence souple par le législateur serait de nature à calmer le débat.At the turn of the century, the working classes fought for a day off in the week, which was granted on Sundays by the legislator in 1906. Four additional christian holidays are also legal. So the right to pray is garanteed for christians. As different populations with various faiths settled in France, this organisation has seemed to violate the principle of equality, and religious freedom. There has been a debate on the question whether some of the days of minority religions should also be observed by all the population. But so far, the legislator has not voted any of these proposals. It remains an issue. The French judge has consistently decided that the people of non christian faiths had the right to be granted a day off to pray on these special days, provided it would not cause prejudice to the organisation they work for. It might help to calm the debate if this

L’océan est un terrain difficile et original permettant de se confronter à l’interdisciplinarité (géographie, océanographie, climatologie, biologie, histoire, économie. Les approches menées au sein de la géographie sont souvent régionales, sectorielles, côtières et appliquées et peu cherchent à s’orienter vers des approches théoriques ou vers la haute mer. Nous ferons ici un état des lieux de la place de l’océan au sein de la géographie et tâcherons d’ouvrir des perspectives de recherche en prenant l’exemple de la navigation à voile et de la notion de territoire en haute mer que nous qualifierons de « merritoire ». Pour le définir, nous proposons d’ouvrir sur les notions de mobilité, discontinuités, réseaux et de paysage marin. Le paysage, reflet de l’interdisciplinarité, apparaît également comme étant une piste pour la gestion de l’espace maritime.The high sea has been little studied within geography. Its characteristics show that it is a complex space and do reflect its alterity. The ocean is a difficult and original fieldwork that invites to be analyzed with interdisciplinary methods (geography, oceanography, climatology, biology, history, economy. The geographical approach has so far mainly been an applied geography and has focused on regional, sectorial and coastal aspects. Few are aiming at theoretical approaches or on the high seas. We will overview the position of the ocean within geography and will try to explore new research perspectives by taking into account sailing and the concept of territory in the high sea that we will define as « maritory ». To define it, we offer to discuss on the terms of mobility, discontinuity, network and seascape. Seascape - example of an interdisciplinary tool- could appear as a method for marine

Painéis reconstituídos de MDF (medium density fiberboard, aglomerado e compensado foram caracterizados e classificados, identificando assim as oportunidades e possíveis limitações quanto à sua utilização. Por meio de diagnóstico realizado em 11 fábricas de móveis, verificou-se que os resíduos de madeira compreendem mais de 90 % do total dos resíduos sólidos gerados. Além da grande quantidade gerada, não foi identificada nenhuma ação integrada entre as fábricas do Polo para o adequado gerenciamento dos resíduos, negligenciando seus riscos ambientais e sanitários, bem como seu potencial energético. Contudo, os teores de umidade e poder calorífico dos resíduos demonstraram potencial para o seu reaproveitamento energético através da produção de briquetes. Os gases gerados em ensaios de combustão dos resíduos não apresentaram substâncias ou compostos tóxicos acima dos limites preconizados pelas normas ambientais, verificando, neste aspecto, um bom desempenho ambiental para o aproveitamento destes resíduos conforme proposto pelo presente estudo. Entretanto, as cinzas dos resíduos de aglomerado BP (baixa pressão e FF (finish foil apresentaram elevadas concentrações de cromo, enquadrando-se como Classe I (perigosos, segundo a ABNT/NBR 10004/2004.

    2012-12-15

    In its Directive 2009/28/EC the European Commission (EC) set an ambitious 20% target on the final consumption of energy from renewable sources (RES) in 2020 (European Commission, 2009). This EU-level target is divided into different domestic targets for each single Member State (MS). The MS-level targets do not always reflect the domestic RES potentials, creating a situation where certain MSs will have to deploy very expensive technologies in order to meet their target, while other countries are expected to reach their target at lower costs and even produce a RES surplus. In order to promote a more balanced distribution of costs, the Directive allows MSs to establish cooperation mechanisms. Three types of cooperation mechanisms are defined: a MS could buy the RES-credits associated with the surplus potential of other MSs via statistical transfers, could finance additional RES deployment in other MSs by engaging in joint projects, or could share (part of) its RES potential with other MSs by establishing joint support schemes.

    Full Text Available A indústria florestal produz resíduos com características e potenciais de utilização muito distintos. Por um lado, a queima de biomassa florestal para obtenção de energia conduz à produção de grandes quantidades de cinzas como produto final e, por outro lado, durante o processo de produção da pasta de papel e na sequência do tratamento por causticação é também produzido um resíduo em quantidades significativas. O objectivo deste trabalho foi avaliar o potencial fertilizante destes dois resíduos, ou seja, das cinzas provenientes da incineração de biomassa florestal e das cinzas provenientes da causticação da pasta de papel, resíduos provenientes da indústria florestal. Num ensaio em vasos estudou-se a resposta do azevém à aplicação de doses crescentes destes resíduos que corresponderiam à aplicação ao solo de 0, 0,5, 1, 3 e 5 toneladas por ha. Verificou-se que a cinza de biomassa florestal pode ser aplicada ao solo, não se observando efeitos negativos na produção ou propriedades do solo. Esta aplicação conduzirá ao fornecimento de alguns nutrientes, nomeadamente K e Ca. Em solos com relação Ca/Mg elevada aconselha-se a aplicação simultânea de Mg. O resíduo proveniente da causticação da pasta de papel, deve ser incorporado no solo com antecedência relativamente à sementeira devido à sua causticidade. Nas culturas plurianuais não deverá ser utilizado. Apresentou valor como correctivo alcalinizante, possuindo elevado teor em Na que conduziu a um aumento significativo da condutividade eléctrica e do Na de troca, não se aconselhando uma aplicação em quantidades superiores a 1 t/ha.Forestry industry originates residues with distinct properties which can have also differences in its management reutilization.

    Full Text Available http://dx.doi.org/10.5902/1980509814589As indústrias de base florestal apresentam baixo rendimento e geram grande quantidade de resíduos, especialmente as indústrias de transformação primária como, por exemplo, as serrarias. No Brasil, estão sendo criadas iniciativas para aliar a utilização desses resíduos à produção de celulose. Dentro deste propósito, o presente trabalho teve como objetivos avaliar o rendimento de uma serraria de médio porte localizada no município de Rio Grande, RS, e promover análises físico-químicas dos resíduos gerados na etapa de desdobro. Foram utilizadas 20 toras de Pinus elliottii, divididas em duas classes diamétricas. Os resíduos, com exceção da serragem, coletados para análises, encontravam-se dispostos no pátio da empresa, na forma de cavacos. As seguintes propriedades físico-químicas dos cavacos foram analisadas: densidade básica, teor de extrativos solúvel em acetona, grupos acetilas, lignina solúvel e insolúvel em ácido (lignina Klason, grupos urônicos e carboidratos. Como principais resultados verificou-se um ligeiro aumento do rendimento em madeira serrada das madeiras de maiores diâmetros em relação às de menores diâmetros. Das análises físico-químicas foram obtidos os seguintes resultados: densidade básica de 0,402 g/cm³, teor de celulose de 37,42% e de 24,37% para hemiceluloses, lignina Klason de 26,75% e teor de extrativos de 3,80%. Concluiu-se, nesse estudo, que o baixo rendimento da serraria foi devido à falta de uma classificação diamétrica e diagramas de cortes apropriados para as toras, o que resulta em maior perda de madeira na forma de resíduos. Em relação às características química e física dos resíduos madeireiros, os resultados mostraram-se dentro dos padrões de qualidade da madeira utilizada para a produção de celulose kraft de fibra longa e, em algumas situações, apresentando vantagens em relação às madeiras mais jovens usualmente

    Full Text Available O artigo busca, em diferentes períodos da história, as percepções sobre os resíduos resultantes da atividade humana. Está dividido em três partes: 1 narra o episódio da peste negra do século XIV, mostrando como ela foi associada aos resíduos produzidos pelo corpo humano; 2 explicita como as prenoções sobre resíduos, ainda hoje, remetem à sujeira, à doença e à morte; 3 descreve as medidas de higiene, a partir do renascimento e a saúde pública no início do século XX, que começa combatendo os agentes microbianos das doenças infecciosas e os seus vetores.This article describes how Man, over history, felt about the residues produced by human activity. The text is divided into three parts: In the first part it tells the story of the black plague pandemic during the XIV century, showing how this disease was associated with the residues produced by the human body. In the second part it explains how the first notions of waste were, and still are, related to dirt, disease and death. Finally, in the third part, it describes the first measures of hygiene in the Renaissance and refers to the first public health actions at the beginning of the XX century, starting to combat the agents of infectious diseases and their vectors.

    Only five of fourteen species of Fucales reported at the end of the XIXth century are currently present in the Albères Coast (France, NW Mediterranean). According to historical data there has been a steady decrease of all the populations since the 1940s. Seven taxa now extinct (Cystoseira crinita, Cystoseira barbata, Cystoseira foeniculacea f. tenuiramosa, Cystoseira spinosa, Cystoseira spinosa var. compressa, Sargassum hornschuchii and Sargassum vulgare) were considered frequent and some of them were the dominant and engineering species in several phytobenthic assemblages. Moreover, only one of the five species left, shows no signs of regression (Cystoseira compressa), two are considered as rare (Cystoseira caespitosa, Cystoseira zosteroides), and one is very rare (Cystoseira elegans). Cystoseira mediterranea, a species that was reported to make a continuous belt along the shores of the Albères coast, has almost disappeared from some areas. Overgrazing by sea urchins, outcompetition by mussels, habitat destruction, scientific research sampling and, probably, human trampling and chemical pollution are to be blamed for the decline of populations thriving in shallow waters. Deep-water species have been affected by an increase in water turbidity and, probably, chemical pollution and direct plant destruction attributed to net fishing. If degradation of the environmental conditions continues, the remaining Cystoseira species will face a most unwelcome prospect. Even after the removal of the causes that led to its die-off, natural restoration of extinct species seems not to be possible because the decline has also affected populations from nearby areas and zygotes are unable to disperse over long distances. Urgent management actions have to be designed in order to improve the current situation of the populations of Fucales in the Albères coast.

    Full Text Available Este século trouxe muitas demandas novas para a gestão dos resíduos sólidos no Brasil. Concernente a alguns geradores específicos (como, por exemplo, serviços de saúde e empresas indus- triais, as leis são muito mais rígidas e existe uma pressão forte para reciclagem de resíduos domésticos - embora seu cumprimento possa levar muito tempo. As universidades desempenham um papel fundamental na sociedade: ao mesmo tempo criam e difundem o conhecimento, e devem ser uma referência em termos de atitudes, formando alunos, quer como profissionais, quer como cidadãos. Este estudo procura relacionar o que acontece na Universidade Federal de Minas Gerais, e na cidade de Belo Horizonte em termos de gestão dos resíduos sólidos. O ensaio considerou exigências externas (leis federais, estadu- ais e locais, as ações gestão ambiental e urbana da cidade, do judiciário - na figura dos promotores públicos - e da sociedade e disposições internas (administração da universidade e comunidade acadêmica, tentando estabelecer elos entre a cidade e a Universidade. A premissa é que os membros da comunidade acadêmica tendem a se comportar do mesmo modo que o cidadão comum, não exercendo o poder de difusor de conhecimentos transformadores da sociedade.

  5. Bacillus cereus Fnr binds a [4Fe-4S] cluster and forms a ternary complex with ResD and PlcR

    Full Text Available Abstract Background Bacillus cereus is a facultative anaerobe that causes diarrheal disease in humans. Diarrheal syndrome may result from the secretion of various virulence factors including hemolysin BL and nonhemolytic enterotoxin Nhe. Expression of genes encoding Hbl and Nhe is regulated by the two redox systems, ResDE and Fnr, and the virulence regulator PlcR. B. cereus Fnr is a member of the Crp/Fnr family of iron-sulfur (Fe-S proteins. Only its apo-form has so far been studied. A major goal in deciphering the Fnr-dependent regulation of enterotoxin genes is thus to obtain and characterize holoFnr. Results Fnr has been subjected to in vitro Fe-S cluster reconstitution under anoxic conditions. UV-visible and EPR spectroscopic analyses together with the chemical estimation of the iron content indicated that Fnr binds one [4Fe-4S]2+ cluster per monomer. Atmospheric O2 causes disassembly of the Fe-S cluster, which exhibited a half-life of 15 min in air. Holo- and apoFnr have similar affinities for the nhe and hbl promoter regions, while holoFnr has a higher affinity for fnr promoter region than apoFnr. Both the apo- and holo-form of Fnr interact with ResD and PlcR to form a ternary complex. Conclusions Overall, this work shows that incorporation of the [4Fe-4S]2+ cluster is not required for DNA binding of Fnr to promoter regions of hbl and nhe enterotoxin genes or for the formation of a ternary complex with ResD and PlcR. This points to some new unusual properties of Fnr that may have physiological relevance in the redox regulation of enterotoxin gene regulation.

  6. Indicadores de resíduos de construção e demolição para construções residenciais novas

    Miguel Mália

    Full Text Available A indústria da construção representa um dos maiores e mais activos sectores da União Europeia (UE, consumindo mais matérias-primas e energia do que qualquer outra actividade económica. Da mesma forma, os resíduos das suas actividades corespondem a uma elevada parcela dos resíduos produzidos em toda a UE. A actual legislação na UE visa criar condições para a implementação de medidas de prevenção e reciclagem de RCD. No entanto, carece de instrumentos que acelerem o desenvolvimento de um sector tão tradicional como o da construção. O presente trabalho tem por objectivo determinar indicadores que possibilitem estimar a quantidade de RCD gerados, ao nível da obra, tanto globalmente como por fluxo de resíduos. A geração de RCD foi estimada para seis sectores específicos: nova construção residencial, nova construção não residencial, demolição residencial, demolição não residencial, reabilitação residencial e reabilitação não residencial. Neste artigo, apresentam-se os resultados para a nova construção residencial. Os dados necessários ao desenvolvimento dos indicadores foram obtidos através de um levantamento exaustivo dos dados de estudos anteriores.

    Full Text Available O serviço de alimentação coletiva é identificado como uma grande fonte de desperdício de alimentos. Para obter dados detalhados de perdas de alimentos e geração de resíduos neste setor, os resíduos de uma unidade de alimentação e nutrição (UAN foram classificados em categorias: perdas no estoque e armazenamento, perdas no processamento dos alimentos, na distribuição e na devolução. O estudo teve como objetivo identificar e quantificar os resíduos gerados em uma UAN inserida em uma multinacional produtora de peças automobilísticas, localizada no município de Taubaté, SP, durante cinco dias e propor ações pertinentes à redução do impacto ambiental baseado no princípio dos três “Erres”. Para servir 2.740 refeições foram gerados 486,6 kg de resíduos sólidos, resultando em um per capita médio de 0,177 kg/comensal/dia de resíduos. A geração de resíduos ficou distribuída em: 58,0% no processamento de alimentos, 31,9% na devolução e o 10,1% no estoque e armazenamento. Do total de resíduos 85% eram orgânicos e derivados de: remoção de partes indesejáveis de hortaliças e carnes, restos de alimentos, sobras dos comensais, alimentos vencidos e amostras de alimentos e 15% eram resíduos compostos de papel/papelão, plásticos e latas. A maior geração de resíduos se deu no descarte de partes não comestíveis dos alimentos, sobras de alimentos produzidos e resto-ingestão, resultados esses relacionados ao desperdício dos alimentos, 100% destinados à compostagem. Quanto aos demais resíduos 80% eram destinados à reciclagem e 20% para o aterro sanitário.

    2009-10-01

    Full Text Available Dans son livre Cinq cents ans d’imprimerie, l’historien S. H. Steinberg plaide pour l’élimination des caractères non-latin et cite le gaélique d’Irlande comme l’exemple même d’une typographie devenue désuète. Si cette critique peut être considérée comme malveillante par certains commentateurs, elle n’en fournit pas moins un cadre utile à une étude des caractères typographiques gaéliques et de leur signification.Comme Steinberg, nous pouvons envisager la typographie gaélique de trois manières.Premièrement, loin d’avoir été développées en Irlande, les fontes gaéliques furent d’abord conçues et fabriquées en Angleterre. Des formes plus tardives apparurent en Belgique, France, Italie, Australie et aux Etats-Unis. Ont-elles une identité essentiellement irlandaise ?Deuxièmement, la création de ces fontes découla, à l’origine, de la politique religieuse d’Elizabeth Ière. Elles devinrent plus tard un instrument de la Contre-réforme et plus tard encore du nationalisme irlandais. En dehors de son utilisation à des fins de propagande, la typographie gaélique a-t-elle jamais véritablement existé ?Enfin, les inventeurs des caractères typographiques gaéliques se sont toujours montrés hostiles à toute évolution susceptible de parvenir à une plus grande lisibilité. La forme de chaque caractère répond davantage à un critère d’authenticité visuelle qu’à une quelconque notion d’efficacité.  Comment l’irlandité est-elle ainsi véhiculée par la typographie ?

    Dayantis J.

    2006-11-01

    Full Text Available On examine dans cet article différentes approches de la thermodynamique des solutions de polymères placées dans leur contexte historique. On rappelle d'abord le modèle du réseau de Flory-Huggins et on en souligne les déficiences. On traite ensuite brièvement de la mécanique statistique des solutions de polymères introduite par Prigogine en 1957 et on montre qu'elle constitue un progrès qualitatif par rapport à la théorie du réseau, mais qu'elle ne prévoit cependant pas de manière quantitative les propriétés de ces solutions. On montre ensuite que le concept de volume libre, qui permet un traitement simplifié de certaines quantités, permet également d'expliquer tout naturellement l'existence d'une deuxième température de séparation en phase lorsque l'on élève la température, propriété qui différencie les solutions de polymères des mélanges de liquidés simples. Enfin, dans une dernière partie, on mentionne brièvement les travaux récents de l'École de Paris, qui traite les solutions de polymères par analogie avec les transitions magnétiques. This article examines différent approaches ta the thermodynamics of polymer solutions set in their historical context. First of all, the Flory-Huggins network model is described and ifs deficiencies are pointed out. Then attention is briefly drawn to the statistical mechanics of polymer solutions as introduced by Prigogine in 1957, and this mechanics is shown to be a qualitative advance compared with the network theory, but it nonetheless does not quantitatively predict the properties of such solutions. It is then shown that the concept of free volume, enabling some quantifies to be treated in a simplified way, also serves to provide a quite natural explanation for the existence of a second phase separation temperature when the temperature is raised, i. e. a property that differentiates polymer solutions from simple liquid mixtures. In the final part, brief mention is made

    MACAN T. T.

    1976-01-01

    Full Text Available MINSHALL et KUEHNE ont signalé que, dans la « Région des lacs » en Angleterre, alors que la faune typique d'un ruisseau à fond pierreux peut monter jusqu'aux sources dans les montagnes, il y a des zones où la faune est pauvre, hormis les Plécoptères. Dans ces dernières eaux, le pH et le taux en calcium sont faibles, comme l'ont montré SUTCLIFFE et CARRICK qui pensent qu'il s'agit d'une pollution atmosphérique. De telles communautés habitent les affluents de la Rivière Lune. La rivière elle-même traverse une gorge où, grâce aux éboulis, le fond est stable. La faune actuelle est riche en espèces et en individus, surtout en larves de Tricoptères avec filet. C'est presque la seule région où les mollusques ne risquent pas d'être écrasés par les pierres roulantes. En aval, dans une longue plaine alluviale, le substrat est instable et, en conséquence, les espèces sont peu nombreuses bien que les individus de quelques-unes soient abondants. Une augmentation de l'enrichissement actuel provenant des villes et des prairies cultivées pourrait provoquer une croissance excessive des algues filamenteuses. Celles-ci font disparaître la vraie faune lithicole et disparaissent elles-mêmes en temps de crue, en emportant vers l'aval les animaux qu'elles hébergent. Au-delà de la plaine, la rivière traverse une région à pierre meulière, sur un lit plat et lisse. Entre deux barrages, ce lit est couvert de mousses habitées par 4 espèces d'éphémères qui ne se trouvent ailleurs, que dans de petites baies où le courant est faible. On a remarqué dans une rivière voisine la disparition de telles espèces après l'amélioration du lit par les ingénieurs.
