  1. Corrigendum: Bounding sea level projections within the framework of the possibility theory Environ. Res. Lett. (2017 12 014012)

    2017-10-01

    Figures 3 and 4 of the article ‘Bounding probabilistic sea-level projections within the framework of the possibility theory’ display a minimum value for sea level rise of 15 cm by 2100 with respect to the 1986-2005 mean for the RCP 8.5. The value of 15 cm is consistent with sea level rise rates dropping back to velocities observed during the 20th century according to recent studies, but not to the current sea level rise velocity of 3.4 mm yr-1, as incorrectly stated in the article. This error has no impact on the rest of the article, including its arguments and conclusions, but it is potentially confusing for scientists willing to reproduce the left side of figures 3 and 4. We apologise for any inconvenience caused.

    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)

    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.

    Full Text Available Achieving sustainable agriculture and producing enough food for the increasing global population will require effective strategies to cope with harsh environments such as water and nutrient stress, high temperatures and compacted soils with high impedance that drastically reduce crop yield. Recent advances in the understanding of the molecular, cellular and epigenetic mechanisms that orchestrate plant responses to abiotic stress will serve as the platform to engineer improved crop plants with better designed root system architecture and optimized metabolism to enhance water and nutrients uptake and use efficiency and/or soil penetration. In this review we discuss such advances and how the generated knowledge could be used to integrate effective strategies to engineer crops by gene transfer or genome editing technologies.

    Full Text Available The agINFRA project (www.aginfra.eu was a European Commission funded project under the 7th Framework Programme that aimed to introduce agricultural scientific communities to the vision of open and participatory data-intensive science. agINFRA has now evolved into the European hub for data-powered research on agriculture, food and the environment, serving the research community through multiple roles. Working on enhancing the interoperability between heterogeneous data sources, the agINFRA project has left a set of grid- and cloud- based services that can be reused by future initiatives and adopted by existing ones, in order to facilitate the dissemination of agricultural research, educational and other types of data. On top of that, agINFRA provided a set of domain-specific recommendations for the publication of agri-food research outcomes. This paper discusses the concept of the agINFRA project and presents its major outcomes, as adopted by existing initiatives activated in the context of agricultural research and education.

    Buchanan, B J; Filkins, J P

    1976-07-01

    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.

  17. 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.

    Spectral signatures of two distinct forest test areas were identified from digital data including 15 LANDSAT scenes covering the same geographical area: a broad-leaved forest (oak and beech) and a coniferous forest (scotch pine). Seasonal variations of the signatures were examined and were expressed in terms of various data: date, solar height and phenological state of vegetation cover. Results were compared to these obtained from other perennial surface conditions (grassland, bare soils) . Range of the seasonal variations of radiance is noted, as well as evolutionary peculiarities on each band and between themes. Rationing of spectral bands (particularly MSS 5 and 7) and their variation with time are specified [French] A partir des données numériques de 15 scènes LANDSAT sur un même secteur géographique, l e s auteurs définissent les signatures spectrales de deux milieux forestiers distincts: une futaie de chênes-hêtres et une futaie de pins sylvestres, et ils étudient l a variation saisonnière de ces signatures. Ils tentent d'interpréter cette variabilité en fonction de la date de saisie des données, donc de l a hauteur du soleil et de l'état phénologique du couvert végétal. Ils comparent les résultats 5 ceux obtenus sur d'autres milieux pérennes (prairie, sols nus). L'amplitude des variations saisonnières des luminances est précisée, ainsi que les modalités particulières de l'évolution sur certains canaux ou entre les deux thèmes. Les auteurs étudient également les rapports de luminance inter-canaux (5 et 7 en particulier) et leur évolution dans le temps.

    2009-01-01

    The main point of the comment [Appl. Phys. Lett. 94, 076101 (2009)] is that Eq. (2) and consequentially Eq. (3) of the commented paper [Appl. Phys. Lett. 92, 021503 (2008)] require correction. The alternative equation suggested in the comment is derived using Kirchhoff's voltage rule. The comment consider only the energy distribution in the inductive components and the resultant equation confirms a progressive lowering of the I pinch /I peak ratio as the static inductance L 0 is reduced, lowering from 0.87 to 0.31 as L 0 is reduced from 100 to 5 nH according to the revised formula corresponding to Eq. (3), compared to 0.63-0.25 according to Eq. (3). This progressive lowering of the ratio I pinch /I peak due to the inductive energy distribution is one of two factors responsible for the pinch current limitation. The other factor is the progressive reduction in the L-C interaction time compared to the current dip duration denoted by δ cap in Eq. (2). The comment does not deal with δ cap at all; hence, its conclusion based on inductive energy distribution only is not useful, since in the low L 0 region when pinch current limitation begins to manifest, δ cap becomes more and more the dominant factor. In any case, the results of the paper do not depend on Eqs. (2) and (3), which are used in the paper only for illustrative purposes

    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: • 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

    We update our earlier study [Phys. Lett. B 544 (2002) 239], which was inspired by the 2002 SNO data, on the implications of the results of the solar neutrino experiments for the predictions of the effective Majorana mass in neutrinoless double beta-decay, vertical bar vertical bar. We obtain predictions for vertical bar vertical bar using the values of the neutrino oscillation parameters, obtained in the analyzes of the presently available solar neutrino data, including the just published data from the salt phase of the SNO experiment, the atmospheric neutrino and CHOOZ data and the first data from the KamLAND experiment. The main conclusion reached in the previous study [Phys. Lett. B 544 (2002) 239] of the existence of significant lower bounds on vertical bar vertical bar in the cases of neutrino mass spectrum of inverted hierarchical (IH) and quasi-degenerate (QD) type is strongly reinforced by fact that combined solar neutrino data (i) exclude the possibility of cos2θ o =0 at more than 5 s.d., (ii) determine as a best fit value cos2θ o =0.40, and (iii) imply at 95% C.L. that cos2θ o ∼>0.22, θ o being the solar neutrino mixing angle. For the IH and QD spectra we get using, e.g., the 90% C.L. allowed ranges of values of the oscillation parameters, vertical bar vertical bar ∼>0.010 eV and vertical bar vertical bar ∼>0.043 eV, respectively. We also comment on the possibility to get information on the neutrino mass spectrum and on the CP-violation in the lepton sector due to Majorana CP-violating phases

    The development of the hydrocarbon resources of the North Sea has resulted in both offshore and onshore environmental repercussions, involving the existing physical attributes of the sea and seabed, the coastline and adjoining land. The social and economic repercussions of the industry were equally widespread. The dramatic and speedy impact of the exploration and exploitation of the northern North Sea resources in the early 1970s, on the physical resources of Scotland was quickly realised together with the concern that any environmental and social damage to the physical and social fabric should be kept to a minimum. To this end, a wide range of research and other activities by central and local government, and other interested agencies was undertaken to extend existing knowledge on the marine and terrestrial environments that might be affected by the oil and gas industry. The outcome of these activities is summarized in this paper. The topics covered include a survey of the marine ecosystems of the North Sea, the fishing industry, the impact of oil pollution on seabirds and fish stocks, the ecology of the Scottish coastline and the impact of the petroleum industry on a selection of particular sites.

    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

    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.

    Scintigraphy of the reticuloendothelial system (RES) was performed in 19 patients with polycythemia vera (PCV) and in 18 with secondary or relative polycythemia (PS). Bone marrow extension was found in all patients with PCV and in 11 of 18 patients with PS. The patients with PCV had a higher degree of extension than those with PS. Increased pelvic bone marrow activity was found in 16 of 19 PCV patients, but in none with PS. Splenomegaly was found in 9 patients with PCV, and in none with PS. It is concluded that RES scintigraphy in the majority of patients may differentiate between PCV and PS using the parameters pelvic bone marrow activity, bone marrow extension and splenic size.

    Full Text Available Para que um resíduo sólido seja disposto adequadamente, é necessário classificá-lo segundo as Normas Técnicas Brasileiras, cuja principal é a NBR 10.004. Resíduos sólidos industriais não-inertes normalmente têm sido encaminhados para disposição final em aterros controlados, que em sua maioria não operam de forma eficiente, além de estarem geralmente localizados próximos a núcleos populacionais e ecossistemas importantes. A fim de avaliar a toxicidade potencial dos resíduos produzidos em indústrias de diferentes segmentos, 21 amostras foram analisadas de acordo com as orientações descritas na NBR 10.004. Das amostras estudadas, 18 foram classificadas como resíduos não-inertes. Os principais parâmetros que contribuíram para a classificação das amostras em resíduos não-inertes foram: alumínio, ferro, manganês, fenol e surfactantes. Destes, o alumínio, o manganês e o fenol são as substâncias de maior interesse toxicológico para a saúde humana e ambiental, uma vez que podem alterar a qualidade das águas subterrâneas localizadas nas áreas de disposição de resíduos.According to Brazilian recommended technical procedures (mainly NBR 10,004, solid waste must be previously classified in order to be disposed of adequately. Non-inert industrial solid waste is being dumped in landfill areas, most of which operate inefficiently and are located near the population and important ecosystems. In order to evaluate the potential toxicity of solid waste produced by various types of industries, 21 samples were analyzed according to NBR 10,004 procedures. Of these, 18 were classified as non-inert solid waste. The main substances contributing to the classification of these samples as non-inert waste were: aluminum, iron, manganese, phenol, and surfactants. Aluminum, manganese, and phenol are the main toxicologically relevant substances for human and environmental health because they can alter the quality of groundwater

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

    Energy Technology Data Exchange (ETDEWEB)

    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

    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

    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....

    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.

    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. Lopez, Environ Microbiol 17:555-565, 2015, https://doi.org/10.1111/1462-2920.12527; L. S. Cairns, L. Hobley, and

    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.

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

    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.

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

    2018-02-08

    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.

    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 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 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.

    Full Text Available O presente trabalho avaliou a capacidade de adsorção do corante azul de metileno nos resíduos da palha de milho e da bainha do palmito pupunha in natura. 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.

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

    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.

    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.

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

    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.

  17. Energy and climate hand-in-hand: Financing RES-E support with carbon revenues

    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.

    In May, 2007, a series of tasks were implemented in the actives of the client at Patagonia, Argentina, with the purpose of applying a Pipeline Integrity System. The purpose of this system is to effectively operate their facilities in such a way that no adverse effects are suffered by their employees, the environment, or the public at large, which is one of the main goals followed by any oil pipeline operator. In this paper, all tasks, inspections, controls and records made by the operator about gas and liquid hydrocarbons Pipelines contemplated by local requirements, NAG 100 and Resolution 1460 are described. Firstly, a description of gas and liquid hydrocarbons transport systems was made. This description consisted in the recollection of basic information about construction, maintenance, operation and inspection. Later, tasks to complete the ILI process started by the company in the past were implemented. This implementation consisted in the analysis of inspections that were made, priority of anomalies to verify, definition of verifications, direct assessment and analysis of the results. A gap analysis was made with the purpose of stating the compliance level of the normative requirements for each system. This analysis consisted in the determination of the company's practices about applicable regulations. As a result of this, a series of duties were developed from the collection and integration of information, using the database that was already implemented by the company. A risk analysis was also made, based on the determination of the kind of events or adverse conditions that can make an impact in the oil pipeline, the possibilities that these events or condition can conduct to a failure, and the seriousness of the possible consequences that these failures can produce. With the results of the risk analysis, the Inspection plan developed by the company was refreshed and it resulted in an improvement Plan in data collection and identification of sensitive

    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

    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.

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

    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

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

    International Nuclear Information System (INIS)

    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.)

    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

    Apuani, Tiziana; Corazzato, Claudia

    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

    2017-09-29

    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.

  2. 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.

  8. Ethical dilemmas in medical humanitarian practice: cases for reflection from Médecins Sans Frontières.

    Science.gov (United States)

    Sheather, Julian; Shah, Tejshri

    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.

    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. The network system analysis method enables to indicate energy flows in the region as well as indicate pros and cons of using renewable energy technologies. - Highlights: • RES integration into the regional energy development scenarios is done. • Innovative process network system (PNS) analysis method is used. • PNS method is used to optimize the use of local and renewable resources. • Analysis of energy flow in region using PNS method is done

    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

    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.

  2. Decoherence control in different environments

    We investigate two techniques for controlling decoherence, focusing on the crucial role played by the environmental spectrum. We show how environments with different spectra lead to very different dynamical behaviors. Our study clearly proves that such differences must be taken into account when designing decoherence control schemes. The two techniques we consider are reservoir engineering and quantum Zeno control. We focus on a quantum harmonic oscillator initially prepared in a nonclassical state and derive analytically its non-Markovian dynamics in the presence of different bosonic thermal environments. On the one hand, we show how, by modifying the spectrum of the environment, it is possible to prolong or reduce the life of a Schroedinger cat state. On the other hand, we study the effect of nonselective energy measurements on the degradation of quantumness of initial Fock states. In this latter case, we see that the crossover between quantum Zeno and anti-Zeno effects, discussed by Maniscalco et al. [Phys. Rev. Lett. 97, 130402 (2006)], is highly sensitive to the details of the spectrum. In particular, for certain types of spectra, even very small variations of the system frequency may cause a measurement-induced acceleration of decoherence rather than its inhibition.

    We present a focus issue of Environmental Research Letters on the ‘Recent dynamics of arctic and sub-arctic vegetation’. The focus issue includes three perspective articles (Verbyla 2011 Environ. Res. Lett. 6 041003, Williams et al 2011 Environ. Res. Lett. 6 041004, Loranty and Goetz 2012 Environ. Res. Lett. 7 011005) and 22 research articles. The focus issue arose as a result of heightened interest in the response of high-latitude vegetation to natural and anthropogenic changes in climate and disturbance regimes, and the consequences that these vegetation changes might have for northern ecosystems. A special session at the December 2010 American Geophysical Union Meeting on the ‘Greening of the Arctic’ spurred the call for papers. Many of the resulting articles stem from intensive research efforts stimulated by International Polar Year projects and the growing acknowledgment of ongoing climate change impacts in northern terrestrial ecosystems.

    The project included selected insulation products like products made of cellulose fibres, flax fibres and perlite, which could all be used in external walls, internal walls, cavity walls and lofts. Up till now only products of mineral fibres were used. The aim of the project was to collect environmental data for selected products for the whole lifetime and to assess environmental impacts caused by the products. The total environmental impacts of a building element, e.g. external walla, were calculated from environmental data of the products. The impacts could be shown in a diagram, eco-profiles, which also showed contributions of the materials to the total impacts. The calculations used the principles of life cycle assessment (LCA), but today LCA does not include health aspects in the indoor climate or environmental health aspects caused by disposal processes. Therefore, this project included qualitative assessments for these two life cycle phases. The project did not treat impacts in the working environment as these health aspects are covered by other projects (COWI, 2000 and Engelund et al., 1999). (au)

Development of oil and gas fields in the arctic seas located few hundreds miles from shore is according to expert opinion the most challenging project in the world. Without international cooperation, coordination of all activities and use of modern and proven technologies for production of hydrocarbons, their transport, efficient safety and environmental protection tools the realization of such a project would be questionable. Le plateau continental arctique est considéré comme la zone comportant le potentiel inexploré le plus important tant en termes d’huile et de gaz qu’en ressources en hydrocarbures non conventionnels tels que les hydrates de gaz. En dépit d’une vision courante selon laquelle l’Arctique possède des ressources abondantes en hydrocarbures, des débats se poursuivent sur le potentiel énergétique de cette région. Les lignes directrices de telles discussions reposent sur la géopolitique, les questions environnementales, l’évaluation et la délimitation des ressources arctiques, la technologie disponible pour le succès de leur exploitation et les perspectives d’évolution de la demande en énergie. La partie russe est reconnue comme étant la plus importante concernant les ressources en huile et gaz des nations arctiques.

    1995-04-01

    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.

    Cui, Qiannan; Zhao, Hui

    2015-04-28

    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.

    RES Equipment Sales of Dryden, Ontario is leading the development of a battery-powered personnel utility vehicle for underground mining applications. Among the advantages of the battery-powered personnel carrier are quietness of the carrier and zero emissions, which eliminates particulates from diesel engines and reduces the need for ventilation. This article discussed the design and building of the vehicle. It was designed to accommodate up to 3 battery packs, depending on the frequency of use. Swapping batteries takes between 2 or 3 minutes. Spent batteries must be plugged in for 6 hours and rest for another 6 to 8 hours before being ready for service. The vehicle accommodates 2 or 3 people and travels at speeds of 6 to 8 miles per hour. This article also provided background information on RES Equipment Sales. The company remanufactures underground mining equipment, including load-haul-dump machines, jumbos, haul trucks and utility vehicles. In addition, the company sells and services new equipment, including Oldenburg Cannon jumbos, scalers and utility vehicles, as well as Canun International pneumatic rock drills and NPK rock breakers. 1 ref., 1 fig.

    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.

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.)

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

    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

    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

    benefits of RES, there may be valid reasons for policy makers not to employ auctions, since under particular circumstances it may be desirable not to control quantities but the price. As such, they raise the question whether pure support cost minimisation should be the only goal when implementing......This report concludes the work carried out in the course of Task 6.2 of the AURES project. It is its aim to compare auctions with alternative policy instruments and in particular, to examine under which circumstances auctions may be superior and inferior to achieve intended policy targets....... For that purpose, we identify a number of potential drivers that might affect an instrument’s effectiveness, its efficiency and further success criteria. Among this list of relevant drivers, the basis for our analysis is the factor risk, where our core focus is on risk for policy makers. Assuming a world...

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

    2013-07-01

    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.

    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

Neste trabalho, objetivou-se avaliar os resíduos de indústrias do pólo moveleiro de Ubá/MG. No levantamento quantitativo, constatou-se que as empresas geraram resíduos dos mesmos tipos de painéis de madeira. Os resíduos mais comuns foram de aglomerado e MDF (Medium Density Fiber. Observou-se grande variabilidade das dimensões desses resíduos, principalmente em sua largura. Concluiu-se que alguns resíduos não apresentaram dimensões adequadas para a confecção de determinados objetos e que se torna necessária uma seleção prévia desses resíduos para direcioná-los a trabalhos mais minuciosos, de forma a viabilizar a sua utilização.The furniture industry generates an amount of residues, which, normally, is discarded in the environment or destined to steam production in boilers. The handmade production of small wood board objects is an outstanding alternative to take advantage of these residues. The general aim of this study was to evaluate residues in furniture industries located at the pole of Ubá/MG. Through the survey and the analysis of the data, one established that the industries generate residues from the same kind of wood board. The most common residues were of particleboard and MDF (Medium Density Fiber. One observed a great diversity of residue dimensions, mainly in width. One concluded that some residues did not present adequate dimensions for the manufacturing of some objects and that there is a necessity of previous residues selection, in order to destine them to more detailed works and make possible their use.

    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.

    The paper explores the role of convenient shopping in establishing a sense of comfort for Europeans in a colonial environment. So far, there has been little investigation into how Belgian retailers tried to gain a firm foothold in the Congo, how they presented themselves and promoted their wares. This paper examines the activities of the colonial department of Delhaize Frères & Cie 'Le Lion', Belgium's first and largest food multiple. It examines how this large grocery chain tried to establish itself in the Congo, what motivations it had to extend its business to the colony, what audience it wished to reach, what products and services it had to offer and what sales and marketing strategies were used. It appears that convenient shopping was one of the key selling points Delhaize's advertising, while also characterising its products as indispensable for Europeans' comfort, moral respectability and homely warmth in a so-called primitive, backward environment.

  9. Adaptive Fuzzy Control for Power-Frequency Characteristic Regulation in High-RES Power Systems

    Directory of Open Access Journals (Sweden)

    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.

    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.

    2012-01-01

    gestão dos resíduos sólidos vem se tornando um tema cada vez mais relevante, uma vez que os espaços para disposição final do lixo nos centros urbanos são escassos e valorizados. A prática da reciclagem desponta como uma das melhores alternativas para a redução do volume de resíduos enviados aos lixões e aterros sanitários, ao mesmo tempo em que possibilita seu reaproveitamento, preservando os recursos naturais e gerando economia de energia. Como forma de promoção dessa prática,...

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

    Energy Technology Data Exchange (ETDEWEB)

    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. 

  7. Immunoreactive serum opsonic alpha 2 sb glycoprotein as a noninvasive index of RES systemic defense after trauma.

    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

  14. Probing in-plane anisotropy in few-layer ReS2 using low frequency noise measurement

    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.

  15. 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.

  9. 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

    Full Text Available Os efeitos de resíduos de plantas cultivadas e seus extratos sobre Sclerotinia sclerotiorum são poucos conhecidos. Três experimentos foram conduzidos, com resíduos de plantas cultivadas e seus extratos etanólicos e suas partições. Resíduos e extratos de culturas de aveia, ervilhaca, feijão, milheto, milho e trigo foram avaliados em condições controladas. Escleródios cobertos com resíduos de aveia, ervilhaca, feijão e milheto não germinaram carpogenicamente. Extratos etanólicos de resíduos de aveia e ervilhaca mostraram-se eficientes na inibição da germinação carpogênica, enquanto que do milheto e do trigo não diferiram da testemunha. Todas as partições de extratos etanólicos avaliadas reduziram a germinação carpogênica. Resíduos vegetais afetaram negativamente o número de apotécios emitidos por escleródio.

    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

    R. C. O. Romano

    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.

    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. Nevertheless the legal systems and practices of other countries of Europe reveal the pragmatic judgements of the European Court of Human Rights and their comparable reserve, even if their base is necessarily different (Second part.As a whole, the decisions of the Court make it possible to note that the Member States of the Council of Europe sometimes have restrictive attitudes

    The Advanced Distributed Simulation (ADS) Synthetic Environments Program seeks to create robust virtual worlds from operational terrain and environmental data sources of sufficient fidelity and currency to interact with the real world. While some applications can be met by direct exploitation of standard digital terrain data, more demanding applications -- particularly those support operations 'close to the ground' -- are well-served by emerging capabilities for 'value-adding' by the user working with controlled imagery. For users to rigorously refine and exploit controlled imagery within functionally different workstations they must have a shared framework to allow interoperability within and between these environments in terms of passing image and object coordinates and other information using a variety of validated sensor models. The Synthetic Environments Program is now being expanded to address rapid construction of virtual worlds with research initiatives in digital mapping, softcopy workstations, and cartographic image understanding. The Synthetic Environments Program is also participating in a joint initiative for a sensor model applications programer's interface (API) to ensure that a common controlled imagery exploitation framework is available to all researchers, developers and users. This presentation provides an introduction to ADS and the associated requirements for synthetic environments to support synthetic theaters of war. It provides a technical rationale for exploring applications of image understanding technology to automated cartography in support of ADS and related programs benefitting from automated analysis of mapping, earth resources and reconnaissance imagery. And it provides an overview and status of the joint initiative for a sensor model API.

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.

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.

    Full Text Available The purpose of this research is the identification of a paradigm which fixes the basic concepts and the type of logical relationships between them, whereby direct, govern and evaluate choises on new technologies. The contribution is based on the assumption that the complexity of knowledge is correlated with the complexity of the learning environment. From the existence of this correlation will descend a series of consequences that contribute to the definition of a theoretical construct in which the logical categories of learning become the guiding criteria on which to design learning environments and, consequently, also the indicators on by which to evaluate its effectiveness.

    Full Text Available Com a Rio+20 retoma-se a discussão de estratégias para conciliar desenvolvimento com proteção dos ecossistemas. Um tema apenas tangenciado nessas discussões é o gerenciamento dos resíduos sólidos urbanos. Diante da institucionalização da Política Nacional de Resíduos Sólidos, busca-se contribuir para esse debate, bem como apontar caminhos para o enfrentamento dessa questão, privilegiando a inclusão social. Para isso, foram utilizados documentos e informações sobre a gestão de resíduos sólidos, e a literatura científica especializada. Observa-se que o inadequado gerenciamento dos resíduos sólidos gera impactos imediatos no ambiente e na saúde, assim como contribui para mudanças climáticas. Considerando as limitações das opções de destinação final para os resíduos, é imprescindível minimizar as quantidades produzidas por meio da redução, reutilização e reciclagem. Nesse contexto, destaca-se o papel dos catadores, que vêm realizando um trabalho de grande importância ambiental. Dadas as fragilidades desse segmento populacional, é preciso delinear políticas públicas que tornem a atividade de catação mais digna e com menos riscos e que, ao mesmo tempo, garantam renda, para assim caminhar rumo a um desenvolvimento mais saudável, justo e sustentável.Strategies to reconcile development with the protection of ecosystems will yet again be discussed at the forthcoming Rio +20 Summit. The management of solid urban waste is an issue which has barely been touched upon in such discussions. Given the institutionalization of the National Solid Waste Policy, this paper seeks to contribute to this debate and to single out alternatives to tackle this issue with an emphasis on social inclusion. For this purpose, specialized scientific literature was consulted as well as information on solid waste management. It is clearly seen that inadequate management of solid waste has immediate impacts on the environment and health

    Full Text Available Descreve-se o aproveitamento do resíduo do desfibramento das folhas de Agave sisalana, como um larvicida para o combate a mosquitos transmissores de doenças tropicais. 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.

    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.

    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.

    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.

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.

    2015-05-01

    The management of safety culture in international and culturally diverse organizations is a concern for many high-risk industries. Yet, research has primarily developed models of safety culture within Western countries, and there is a need to extend investigations of safety culture to global environments. We examined (i) whether safety culture can be reliably measured within a single industry operating across different cultural environments, and (ii) if there is an association between safety culture and national culture. The psychometric properties of a safety culture model developed for the air traffic management (ATM) industry were examined in 17 European countries from four culturally distinct regions of Europe (North, East, South, West). Participants were ATM operational staff (n = 5,176) and management staff (n = 1,230). Through employing multigroup confirmatory factor analysis, good psychometric properties of the model were established. This demonstrates, for the first time, that when safety culture models are tailored to a specific industry, they can operate consistently across national boundaries and occupational groups. Additionally, safety culture scores at both regional and national levels were associated with country-level data on Hofstede's five national culture dimensions (collectivism, power distance, uncertainty avoidance, masculinity, and long-term orientation). MANOVAs indicated safety culture to be most positive in Northern Europe, less so in Western and Eastern Europe, and least positive in Southern Europe. This indicates that national cultural traits may influence the development of organizational safety culture, with significant implications for safety culture theory and practice. © 2015 Society for Risk Analysis.

    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.

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.

  5. 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 When developing learning resource banks for telearning, it is important to recognize known barriers to the re-use of learning objects and some possible solutions. First, in order that the resources be reused, they must have been created in a modular fashion, separating the resources from their intended context, storing separately the documents and their use in scenarios, or in the case of executable code in autonomous segments. Next, in order to promote the gradual exploration, understanding, evaluation and choice of learning objects, it is important to link the resources not only with metadata, but also explicit documentation on the theoretical and practical aspects of their use, as well as any relevant evaluation material. Finally, if we really want these resource banks to hold this rich ancillary information, we need to build tools that support this contextualization and the activities of all the actors in the telelearning environment from conception, through development and use.

    Full Text Available In keeping with the University of Cape Town’s commitment to social responsiveness (http://www.socialresponsiveness.uct.ac.za/, this article traces the process that underpinned the development and introduction of a postgraduate programme in Disaster Risk Science (DRS. It foregrounds the programme’s conceptualisation within the Department of Environmental and Geographical Science (EGS at the University of Cape Town (UCT, with particular emphasis on examining how disciplinary and theoretical coherence was balanced with cross-disciplinary application and social responsiveness. The article begins by describing the contextual conditions external to UCT’s formal teaching and learning environment that provided the necessary impetus for the new programme. It also traces the iterative relationship between context and curriculum that occurred over the period 1998–2008. This engagement was facilitated and mediated by the Disaster Mitigation for Sustainable Livelihoods Programme (DiMP, an interfacing research and advocacy unit, located within UCT’s Department of Environmental and Geographical Science. An explanation of subsequent content and sequencing of the postgraduate curriculum then follow. They illustrate the programme’s articulation with South Africa’s newly promulgated disaster management legislation, as well as its relevance and rigour in relation to the complex risk environment of South Africa’s Western Cape. The article specifically applies a transdisciplinary lens to the new programmme, in which Disaster Risk Science is conceptualized as a Mode 2 knowledge, but one that draws theoretically and methodologically on environmental and geographical science as its foundation or Mode 1 domain. It concludes by examining the DRS programme’s positive contributions both to scholarship and local risk management practices as well as the obstacles that constrained the new programme and continue to challenge its institutional sustainability.

    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.

    2008-01-01

    The intrauterine environment has a strong influence on pregnancy outcome. The placenta and the umbilical cord together form the main supply line of the fetus. Amniotic fluid also serves important functions. These three main components decide whether there will be an uneventful pregnancy and the successful birth of a healthy baby. An insult to the intrauterine environment has an impact on the programming of the fetus, which can become evident in later life, mainly in the form of cardiovascular diseases, diabetes, and certain learning disabilities. The past two decades have witnessed major contributions from researchers in this field, who have included ultrasonologists, epidemiologists, neonatologists, and pediatricians. Besides being responsible for these delayed postnatal effects, abnormalities of the placenta, umbilical cord, and amniotic fluid also have associations with structural and chromosomal disorders. Population and race also influence pregnancy outcomes to some extent in certain situations. USG is the most sensitive imaging tool currently available for evaluation of these factors and can offer considerable information in this area. This article aims at reviewing the USG-related developments in this area and the anatomy, physiology, and various pathologies of the placenta, umbilical cord, and the amniotic fluid

    Full Text Available Combining availability, viability, sustainability, technical options, and environmental impact in an energy-planning project is a difficult job itself for the today’s engineers. This becomes harder if the potential investors also need to be persuaded. Moreover, the problem increases even more if various consumptions are considered, as their patterns depend to a large extent on the type of facility and the activity. It is therefore essential to develop tools to assess the balance between generation and demand in a given installation. In this paper, a valuable tool is developed for the seamless calculation of the integration possibilities of renewable energies and the assessment of derived technical, financial and environmental impacts. Furthermore, it also considers their interaction with the power grid or other networks, raising awareness of the polluting emissions responsible for global warming. Through a series of Structured Query Language databases and a dynamic data parameterization, the software is provided with sufficient information to encode, calculate, simulate and graphically display information on the generation and demand of electric, thermal and transport energy, all in a user-friendly environment, finally providing an evaluation and feasibility report.

    In this study, a direct sulfidation reaction of ammonium perrhenate (NH4ReO4) leading to a synthesis of rhenium disulfide (ReS2) is demonstrated. These finding 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 (EDX) spectroscopy, X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), transmission electron microscopy (TEM), Raman spectroscopy, thermogravimetric analysis (TGA) and differential scannig calorimetry (DSC). The results indicated the formation of a lower symmetry (1Td) ReS2 with a low degree of layer stacking. © 2017 IOP Publishing Ltd.

    Full Text Available L'accroissement des contraintes subies par les matériaux utilisés dans les techniques pétrolières et parapétrolières et liées aux températures et pressions élevées ainsi qu'aux agressions chimiques, fait que l'on exige de ces matériaux qu'ils soient de plus en plus performants. Ceci implique, pour les concepteurs et utilisateurs de matériel comportant des élastomères en contact avec les hydrocarbures, une connaissance actualisée des produits existants, lesquels sont en constante évolution. On commence donc par décrire les principales familles d'élastomères résistant en milieu pétrolier actuellement disponibles sur le marché. Puis, après avoir évoqué les problèmes que rencontrent les industries pétrolière et automobile dans l'utilisation des élastomères et présenté sommairement les résultats de travaux réalisés à l'Institut Français du Pétrole (IFP, on définira quelques axes de recherches dont la finalité est de participer à l'amélioration des techniques pétrolières dans le sens d'une meilleure fiabilité et d'une réduction des coûts. The materials used in the oil and automotive industries are being subjected to higher and higher mechanical, thermal and chemical stresses, so these materials, and especially elastomers, have to be more and more resistant. For designers and users of equipment containing elastomers in contact with hydrocarbons, this requires an updated understanding of existing products. The aim of this article is thus to describe, first of all, the leading families of resistant elastomers now available for use in a petroleum environment, with particular emphasis on chlorinated, fluorinated, acrylic and nitrile rubbers and their derivatives, which have evolved greatly in recent years with the appearance of new varieties and new types of elastomers, such as Atlas, Vamac, Eypel, etc. For each family of elastomer, the structure is described along with the vulcanization method, its properties

    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.

    Devils Lake, located in Ramsey and Benson County in North Dakota is a sub-basin of the Red River of the North. Although it lies entirely within the Red River Basin, it has no natural outlet at current water levels. Since its inception during the glacier period, Devils Lake has been either rising or falling over the last 10,000 years. Geologic evidence shows that the water level in Devils Lake has fluctuated widely from completely dry (about 1400 feet AMSL) to overflowing into the Sheyenne River (about 1459 feet AMSL). The uncontrolled growth of the lake has been an alarming issue for North Dakota for the past few years as it causes continuous flooding in the surrounding areas. A hydro-climatic model that can provide simulations of the water level of this lake for a 20 or 50 year time frame can be a useful decision making tool. In a mission to achieve that, heterogeneous data obtained from various sources were used to model the lake. Runoff from precipitation is one of the major inputs to the lake and to model that, eight major watersheds that feed directly to the lake were identified using Digital Elevation Models (DEMs) of thirty meter resolution in ArcGIS environment. Hydrology and Arc Hydro tools were used to delineate the watersheds and sub-basins to generate the runoff using the HEC HMS model. The precipitation time series data collected from both NASA and ground stations were used separately to calibrate the runoff model. The generation of time series runoff values for individual basins for four consecutive years (2001-2004) was applied into HEC-ResSim, a reservoir simulation model, to estimate the lake level series considering the elevation-area-storage relationship and evaporation series from previous USGS studies. It is eminent that seepage under the lake played a key role in calibrating the model with observed elevations. The value of seepage flow was varied over increasing elevations as it depends on the height of water column. The model showed an

    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.

    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

    Macreadie et al (this issue; M2017 Environ. Res. Lett.) challenged the conclusion presented by Johannessen and Macdonald (2016 Environ. Res. Lett.) that global estimates of carbon sequestration by seagrass meadows were too high. Here we clarify our global calculation, respond to M2017’s criticisms and explain how the persistent misunderstandings about sediment dynamics within the Blue Carbon community continue to lead to overestimates of carbon sequestration in seagrass meadows. We point out that, although seagrasses appear to have a local effect on carbon sequestration compared with nearby barren sediments, their preferred substrate (slowly-accumulating, coarse sediment) makes them among the least effective coastal environments for burying carbon. We conclude with a proposal for the development of robust international protocols to quantify carbon burial in seagrass meadows that account for sediment accumulation, sediment mixing and carbon remineralization.

    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

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

    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.

    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.

    Previous studies showed that the repeated administration with a low dose of reserpine (RES) induces a gradual appearance of motor signs and cognitive deficits compatible with parkinsonism in rodents. Environmental stimulation has neuroprotective effects in animal models of neurodegenerative damage, including acutely induced parkinsonism. We investigated the effects of exposure to an enriched environment (EE) on motor, cognitive and neuronal (levels of tyrosine hydroxylase, TH and brain derived neurotrophic factor, BDNF) deficits induced by a progressive model of Parkinson's disease (PD) in mice. Male mice were repeatedly treated with vehicle or 0.1mg/kg of RES (s.c) and kept under two housing conditions: standard environment (SE) and EE. In animals kept in SE, the treatment with RES induced deficits in motor function (catalepsy test, open field and oral movements), in novel object recognition (NOR) and plus-maze discriminative avoidance tasks. The environmental stimulation facilitated the recovery of motor deficits assessed by the catalepsy test after the end of treatment. Additionally, exposure to EE prevented the memory deficit in the NOR task. Treatment with RES induced a reduction in the number of TH positive cells in SNpc and VTA, which recovered 30days after the end of treatment. Finally, RES reduced the levels of BDNF in the striatum and the exposure to the EE prevented this effect. These results suggest that plastic brain changes induced by EE promote beneficial effects on the progression of neuronal impairment related to PD. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Dans les carrières de roches massives abandonnées après l'exploitation, l'aridité du sol et le caractère oligotrophe du milieu, conjugués à la présence de parois rocheuses et de plans d'eau au niveau des excavations les plus profondes, sont des éléments favorables à l'expression d'une biodiversité renouvelée et originale. Un inventaire écologique mené sur la carrière de quartzite de Cheffois, située dans le sud du Massif Armoricain, a révélé la richesse biologique de ce type de milieu semi-naturel. Les résultats de l'inventaire ont conduit à distinguer six types d'habitats néoformés correspondant à d'anciens secteurs d'exploitation : (1 un plan d'eau de fosse, (2 une zone de carreau humide, (3 une zone de carreau sec, (4 des fronts de taille d'expositions variées, (5 des remblais boisés, et (6 une galerie souterraine. Ces six types de milieux sont eux-mêmes subdivisés en une mosaïque de petits habitats, favorisant au final une grande biodiversité avec le développement de nombreuses espèces végétales et animales, dont certaines à forte valeur patrimoniale. Replacé dans le contexte du Bas-Bocage vendéen, l'apport écologique de la carrière de quartzite est évalué et confronté aux pertes en biodiversité engendrées par l'ouverture de la carrière. Avec les autres carrières de quartzite situées sur les sites rocheux des environs, elles constituent, ensemble, un réseau de carrières partiellement inondées pouvant contribuer à la création d'un véritable corridor écologique, dans une matrice bocagère actuellement en perte de biodiversité.In abandoned quarries of massive rocks, the aridity and oligotrophic character of soils, combined with the presence of rock walls and water bodies in the deeper excavations, are favourable to the expression of a renewed, original biodiversity.

    Full Text Available A grande diversidade de substâncias potencialmente tóxicas contribuem para a deterioração do meio ambiente. O objetivo deste trabalho foi propor a utilização de bioensaios, através de testes de toxicidade aguda com Daphnia magna e Vibrio fischeri, como mais um parâmetro a ser analisado no extrato solubilizado dos resíduos que, segundo a NBR 10004/04 fossem classificados como classe II A - não inertes ou classe II B - inertes. Realizaram-se, também, testes de toxicidade no drenado dos aterros classe II A e II B. Verificou-se que a toxicidade foi constatada nos extratos solubilizados dos 18 resíduos analisados e que, apenas três das amostras estariam próprias para lançamento, ou seja os resíduos 04, 14 e 15. Já, a toxicidade encontrada no drenado dos aterros, ficou muito superior do que a toxicidade de cada extrato solubilizado analisado separadamente.A great diversity of substances potencially toxic contributes to the deterioration of the environment. The aim of this research was to propose the use of bioassays using Daphnia magna and Vibrio fischeri, as another parameter to be analyzed in the solubilized extraction of waste according to NBR 10004/04 and classified as class II A - non inerts or class II B - inerts. Besides, another test was performed to measure the level of toxicity in the drainage of the landfill class II A and II B. It was verified that the toxicity found in the solubilized extracts of the 18 wastes analysed.Only 3 wastes (04, 14 and 15 were within the emission limits. On the other hand the toxicity found in the drainage of the landfill, from which all the samples came from, was much higher than the individual one.

    Full Text Available Este trabalho apresenta o gesso na construção civil, suas aplicações, características e o desperdício associado. 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.

O trabalho teve como objetivo avaliar aeficiência do processo Fenton no tratamento de lixiviado gerado em aterros sanitários de resíduos sólidos urbanos. As amostras delixiviado foram coletadas no aterro controlado do município de Santa Maria – RS. No experimento foram testados cincotratamentos com diferentes proporções de reagentes (H2O2 e FeSO4 TH2O2/FeSO4: T0,8, T2,0, T3,0, T4,0 e T6,0. Pelos resultados doexperimento com processo Fenton verifica-se uma eficiência média na remoção da demanda química de oxigênio (DQO de47,9%, na turbidez de 53,0% e na cor de 70,7%. Os valores médios da demanda bioquímica de oxigênio (DBO e dacondutividade elétrica aumentaram em 31,3% e 27,1%, respectivamente. No tratamento T0,8 constatou-se a maior remoção daDQO e o maior aumento da biodegradabilidade.

    Full Text Available Le dépôt des salissures marines sur les ouvrages immergés est influencé par plusieurs facteurs et il entraîne des conséquences néfastes, en particulier pour la maintenance des supports de plates-formes de production du pétrole en mer et pour la consommation d'énergie requise pour la propulsion des navires. 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. Various antifouling methods have been considered, including antifouling marine coatings in particular.

    Directory of Open Access Journals (Sweden)

    Joel Vieira Baptista Junior

    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.).

  20. Relativization of the material “res judicata” in the brazilian civil suit Relativização da coisa julgada material no processo civil brasileiro

    2006-12-01

    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.

    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.

  6. Surgeons without borders: a brief history of surgery at Médecins Sans Frontières.

    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.

    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...

Bien que les prévisions soient difficiles dans ce domaine nouveau et en pleine expansion, le marché mondial des biotechnologies pourrait atteindre en l'an 2000, 150 milliards de dollars, dont 40 à 60 % pour les secteurs de la santé, de l'agriculture et de l'alimentation. D'autres secteurs sont également concernés, tels que l'environnement, l'énergie, la bioingénierie (bioréacteurs, enzymes immobilisées, membranes, chromatographie. . . et la chimie. D'un point de vue économique, les biotechnologies sont mieux adaptées à la production de substances à haute valeur ajoutée qu'à celle de produits de gros tonnage. Les produits qui connaissent un développement important sont les enzymes, les amino-acides, les biopolymères. . . Pour les produits de plus gros tonnage, les voies biotechnologiques se heurtent aux réalités économiques, en particulier aux prix comparatifs du pétrole et des céréales ou du sucre. Des procédés, non rentables pour l'instant, ont récemment été mis au point pour des produits tels que l'acrylamide, l'oxyde de propylène, l'hydroquinone, le nylon, le polyphénylène, les diacides. Les Etats-Unis conservent le leadership. Le Japon est sur le point de les rejoindre, tandis que le modèle européen se caractérise par les difficultés de transfert vers l'industrie.

    Full Text Available O objetivo do artigo é discutir a forma como a coincineração de resíduos em fábricas de cimento vem crescendo no Brasil, bem como seus impactos sobre a saúde humana e o meio ambiente. Informações gerais sobre mercado e efeitos sobre a saúde foram obtidas através de revisão bibliográfica e alguns estudos de caso, escolhidos a partir de debate com integrantes da Rede Brasileira de Justiça Ambiental, foram construídos para ilustrar a situação no Brasil. Os estudos encontrados mostraram que, independente do nível de desenvolvimento tecnológico dos países, a saúde dos trabalhadores e das pessoas que moram próximas às fábricas de cimento vem sendo prejudicada pela poluição emitida pelas empresas de cimento, em especial por aquelas que praticam a coincineração. Além disso, no contexto brasileiro, a vulnerabilidade das instituições e populações afetadas tende a agravar este problema. Como conclusão, defende-se o aumento da capacidade institucional dos órgãos brasileiros responsáveis pelo monitoramento das atividades industriais, bem como uma rediscussão mais aprofundada dos aspectos políticos e éticos ligados ao transporte e comércio de resíduos industriais.In this article we discuss the development of hazardous waste co-incineration in cement kilns in Brazil as well as its impacts on health and the environment.

    Full Text Available There are many studies about the biological activities of Vitis vinifera grape seeds, which are rich in phenolic compounds, known by their several health beneficial effects. However, until now there is no data about biological activities of the seeds of V. labrusca, specie found in South and North America. Every year, the global wine production (around 260 million hL generates about 19.5 million ton of wastes, which are usually discarded in the environment. The aim of this research was to evaluate the antioxidant and anti-inflammatory activities of aqueous extracts of seeds from wine wastes of Vitis labrusca (cv. 'Bordo' and 'Isabella'. Both extracts showed significant antioxidant and anti-inflammatory activities, which are positively correlated with total phenolic content, suggesting that these compounds might be the major contributors to the biological activity of these extracts. These results indicate that water extraction from winery wastes is an option to obtain phenolic compounds with antioxidant and anti-inflammatory activities helping to maintain environmental balance.Apesar de existirem vários estudos sobre a atividade biológica de sementes de uva de Vitis vinifera, ricas em compostos fenólicos com reconhecidos efeitos benéficos à saúde, não existem, até o momento, dados a respeito da atividade biológica de sementes de V. labrusca, espécie amplamente encontrada na América do Sul e do Norte. A cada ano, a produção mundial de vinho (cerca de 260 milhões de hL gera, aproximadamente, 19,5 milhões de toneladas de resíduos, usualmente descartados no meio ambiente.

    Full Text Available Empresas envolvidas na mineração de esmeralda e beneficiamento representam uma importante área de desenvolvimento industrial no Brasil, com significativa contribuição para a produção mundial desse minério. Como resultado, grandes volumes de resíduos de esmeralda são constantemente gerados e abandonados no ambiente, contribuindo negativamente para a sua preservação. Por outro lado o interesse no uso do resíduo de mineração como aditivo na produção de material cerâmico tem crescido entre os pesquisadores nos últimos anos. A indústria cerâmica está constantemente buscando a ampliação do mercado para o setor e tentando aperfeiçoar a qualidade dos produtos e aumentar a variedade de aplicações. A tecnologia de obtenção de cerâmica de revestimento que usa resíduos de mineração é um mercado ainda pouco explorado. Neste cenário, o objetivo do presente estudo foi caracterizar o resíduo gerado a partir de mineração de esmeralda, bem como para avaliar seu potencial uso como matéria-prima fundente para a produção de revestimentos cerâmicos. Misturas cerâmicas foram preparadas a partir de matérias-primas caracterizadas por fluorescência de raios X e difração de raios X. Cinco composições foram preparadas utilizando índices de resíduos de esmeraldas de 0%, 10%, 20%, 30% e 40%. As amostras foram preparadas por prensagem, sinterizadas em 1000, 1100 e 1200 ºC e caracterizadas visando estabelecer sua composição mineralógica, absorção de água, retração linear e módulo de ruptura à flexão. Os resultados mostraram que o resíduo de esmeraldas estudado pode ser incorporado na massa de revestimento cerâmico até 20% em substituição ao feldspato sem comprometimento das propriedades do produto final.Companies involved in mining and beneficiation of emerald represent an important area of industrial development in Brazil, with a significant contribution to world production of this ore.

    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.

    Full Text Available O resíduo de rebaixamento de couro wet-blue (RR, também denominado de "serragem de couro", resulta do processo de padronização do couro na indústria de curtimento. Na virada do século, a indústria nacional descartou cerca de 131 mil toneladas do RR na natureza. Neste estudo, investigou-se a possibilidade de uso de RR como um componente de substratos para plantas ornamentais de jardim. Mudas de Tagetes patula L. "Aurora" foram cultivadas em recipientes de 6 cm de altura e 216mL de volume, contendo RR + a mistura CACV (casca de arroz carbonizada e vermiculita superfina, 6:1, v:v nas seguintes proporções volumétricas: 0:1 (100% CACV, 1:3, 1:1, 3:1, 1:0 (100% RR. As mudas foram cultivadas por 23 dias, até o ponto de transplante. A caracterização dos substratos testados baseou-se nos valores de pH, salinidade, densidade seca e nas curvas de retenção de água. A adição de RR reduziu a densidade, aumentou a porosidade e a água retida nas misturas, proporcionando boas condições físicas para o desenvolvimento das mudas de Tagetes. A elevada salinidade do RR (>7g L-1 como KCl e o baixo valor de pH natural do resíduo (3,7, em H2O são características que precisam ser observadas nesta proposta de uso. De forma geral, as mudas mostraram boa tolerância à presença de RR até fração de 50% da mistura. Aumentando a proporção do resíduo, as plantas apresentaram tombamento, menor comprimento do sistema de raízes e menor estabilidade do torrão, que se desagregava ao ser retirada a muda para transplante. Os resultados sugerem a possibilidade de uso de RR como componente de substrato para plantas, desde que observados suas características limitantes e a adição em volumes menores que 50% na mistura.The industrial wet-blue leather standardization process generates a by-product called leather sawdust (RR. At the beginning of this century, the Brazilian tanning industry rejected about 131 thousand tons of RR in the environment. The

    Full Text Available A reutilização dos resíduos gerados pelos diversos setores industriais é uma prática que cada dia é mais utilizado, devido ao comprometimento das indústrias com sua responsabilidade social (proteção ao ambiente ou a exigências dos órgãos de proteção ambiental, já que muitos resíduos não possuem o devido descarte. Na indústria de beneficiamento de gemas a busca pelo reaproveitamento dos resíduos também tem se tornado uma realidade. O presente trabalho tem como objetivo avaliar o reaproveitamento do óleo utilizado como lubrificante na indústria de beneficiamento de gemas, juntamente com água, surfactantes e anticorrosivos. Para preparo das emulsões foram utilizadas amostras de óleo diesel utilizado como lubrificante no setor de corte deste tipo de indústria, mais os seguintes surfactantes: Tween 20, Tween 80, Lauril Éter Sulfato de Sódio (SLES e Cetiol HE. Depois de realizadas análises de pH, viscosidade, densidade e separação de fases nestas emulsões, chegou-se a conclusão que o surfactante Lauril Éter Sulfato de Sódio proporcionava a melhor formulação. Utilizando-se deste resultado, foram preparadas novas emulsões com o surfactante Lauril Éter Sulfato de Sódio e um anticorrosivo, neste caso, o molibdato de sódio. Nestas soluções contendo molibdato de sódio mais óleo e surfactante foram realizadas análises de resistência à corrosão deste sistema, utilizando-se de placas de aço SAE 1020, pela análise de perda de massa. Após estas análises, verificou-se que a adição de um anticorrosivo pode reduzir ou inibir a oxidação, mas em outros casos, como neste estudo, pode promover uma oxidação ainda maiorAbstract The reuse of waste generated by various industrial sectors is a practice that has been increasingly used due to impairment of industries with their social responsibility (environmental protection or the requirements of the protection of the environment, since many residues do not have

    Full Text Available Tanino acil hidrolase conhecida como tanase (E.C: 3.1.1.20 é uma enzima que hidrolisa ésteres e ligações laterais de taninos hidrolisáveis produzindo glicose e ácido gálico. A tanase é uma enzima extracelular, induzível, produzida por fungos, bactérias e leveduras pela fermentação sólida, líquida ou submersa. A fermentação sólida para a produção desta enzima oferece um grande número de vantagens sobre o método de fermentação submersa e líquida convencional. O meio de produção é simples, utiliza resíduos vegetais de uva, cajú, café ou subprodutos como farelo de trigo, arroz ou aveia, acrescidos de ácido tânico. A aplicação de resíduos é uma forma de utilizar substratos alternativos e solucionar problemas de poluição que possam causar. A tanase tem vasta aplicação na indústria de alimentos, sucos, cervejaria e indústria farmacêutica. Objetivou-se com este trabalho selecionar linhagens fúngicas potencialmente produtoras de tanase em resíduos vegetais ricos em taninos. A primeira etapa da seleção foi realizada utilizando como substrato farelo de trigo suplementado com 0,5% de ácido tânico. Dentre as 400 linhagens testadas 6,75% produziram tanase. As linhagens que apresentaram as melhores atividades foram: LAB345G, LAB53G e LAB153G com atividades de 0,2862; 0,2149; 0,1848 U. Essas linhagens foram testadas nos resíduos agroindustriais de café e uva acrescentando 0,5% e 1,5% de ácido tânico ao meio de fermentação. O melhor resultado foi obtido para o resíduo de café com a linhagem LAB153G apresentando atividade de 0.275 U.Tannin acyl hydrolase (E.C: 3.1.1.20 or tannase is an enzyme which hydrolyses ester and depside bonds of hydrolysable tannins releasing gallic acid and glucose.

    Full Text Available O processo de fabricação e comercialização de queijo, sejam eles em grandes agroindústrias ou de modo artesanal em pequenas propriedades rurais, é parte importante na economia brasileira, sobretudo para algumas regiões, a exemplo da região nordeste do Brasil. O objetivo deste trabalho foi efetuar uma caracterização preliminar da produção de queijo, enfatizando o levantamento de suas relações com o meio ambiente e os possíveis aspectos e impactos ambientais decorrentes da produção de queijo. Para tanto, utilizou-se como processo metodológico uma revisão bibliográfica da problemática em estudo a fim de se obter a maior quantidade possível de informações, além de fazer uma correlação com estudos que traz alternativas para o aproveitamento do principal efluente gerado no processo produtivo do queijo, que é o soro derivado do  leite. O soro do leite é um subproduto de alto potencial poluidor, e as empresas perceberam que agregando valor a esse subproduto derivado do leite tem-se uma alternativa viável economicamente, além da redução dos custos com o tratamento de efluentes. Destacando assim, a necessidade de conscientização dos empresários deste segmento, bem como da instalação e/ou adequação de sistemas de tratamento eficientes dos resíduos e efluentes gerados em todas as etapas do processo, haja vista o alto potencial poluidor e impactante desta atividade.The environmental problems resulting from solid waste generated in the production process cheeseAbstract: The process of manufacturing and marketing of cheese, whether in big agribusiness or artisanal way in small farms, is an important part in the Brazilian economy, especially for some regions such as the northeast region of Brazil.

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

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.

    2010-12-01

    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.

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

    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 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.

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 ?

    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

    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.

  13. Linking promotion strategies for RES-E and for demand-side conservation in a dynamic European electricity market: Lessons from the EU projects OPTRES, FORRES and GREEN-X. Volume 1

    Faber, Thomas; Resch, Gustav; Haas, Reinhard; Huber, Claus; Ragwitz, Mario

    2007-01-01

    The objective of this paper is to describe the derivation of least-cost strategies for an significant increase of electricity generation from renewables (RES-E) with minimal costs for European citizens and to investigate the role of accompanying demand-side conservation (DSC) activities. The analyses are conducted by using the model GREEN-X funded by the EC. It allows analyses for both, the EU as a whole as well as for every single member state. Within the model the most important RES-E (e.g. biomass, wind-onshore and off-shore, geothermal, PV, solar thermal ...) technologies are described for every EU-15 country by means of dynamic cost-resource curves. Demand-side conservation measures are considered by aggregated cost-resource curves. To analyse various scenarios different policy schemes can be selected, (e.g. feed-in tariffs, tendering systems, investment subsidies, tax incentives, quotas, tradable certificates) and modelled in a dynamic framework. The corresponding costs and benefits for companies and consumers are an output.The major result is that DSC plays an important role for increasing the share of RES-E. E.g. the same deployment of RES in a conservation scenario leads to 28 % of RES-E by 2020 while in the BAU-scenario this share is only 20 %. Moreover, a certain quota of RES - e.g. 20 % - can be reached much cheaper if a certain share of money is invested in DSC. The core conclusion of this analysis is: On EU level it is of superior importance to introduce integrated policies - policies focusing on the promotion of RES and on energy conservation simultaneously - to reap the utmost benefits from public money invested

    Full Text Available Para estudar a influência de microrganismos nos processos de dissipação de pesticidas em solos, os métodos de esterilização são, particularmente, importantes. Este trabalho, realizado nos laboratórios do Instituto Biológico de São Paulo, em agosto de 1996, avaliou a influência de dois métodos de esterilização de solo - calor úmido (autoclavagem e radiação γ - no processo de liberação de resíduos ligados. Tomaram-se, como exemplos, resíduos ligados do herbicida atrazina em dois tipos de solo (gley húmico e latossolo vermelho-escuro. Nas amostras de solo submetidas à esterilização por calor úmido, a recuperação dos resíduos previamente ligados como resíduos reextraíveis foi de 5,0 e 5,9 vezes superior à dos controles, não submetidos a qualquer processo de esterilização. Portanto, o próprio método de esterilização liberou os resíduos, o que indica que, para estudar a influência de microrganismos na liberação de resíduos ligados, a autoclavagem não é o método mais adequado. Por outro lado, verificou-se que a radiação γ não alterou a recuperação dos resíduos em relação aos controles.

    Full Text Available O setor automotivo é responsável pela geração de resíduos de várias naturezas e que, por força de leis de proteção ambiental, devem ser destinados adequadamente. Neste trabalho foram analisados materiais contaminados por hidrocarbonetos, especificamente o óleo residual resultante das trocas e os componentes de filtros lubrificantes de veículos das montadoras Fiat, Honda e Iveco. Os dados foram coletados em concessionárias localizadas no Estado de Goiás, entre 2014 e 2015. As variáveis analisadas foram: óleo lubrificante novo utilizado nos veículos e óleo usado residual, o tamanho da frota de veículos nacionais e goiana, quantificação dos resíduos componentes do filtro lubrificante, com estimativas para Brasil e Goiás. Os resultados evidenciaram que o montante de óleo usado e contaminado pela frota veicular é elevado e requer destinação adequada por meio de logística reversa, bem como novas tecnologias dos componentes veiculares, em especial do filtro de óleo, para mitigar os impactos do setor.

    Detection of intracellular DNA triggers activation of the stimulator of IFN genes-dependent IFN-stimulatory DNA (ISD) pathway, which is essential for antiviral immune responses. However, chronic activation of this pathway is implicated in autoimmunity. Mutations in TREX1, a 3' repair exonuclease that degrades cytosolic DNA, cause Aicardi-Goutières syndrome and chilblain lupus. Trex1 (-/-) mice develop lethal, IFN-driven autoimmune disease that is dependent on activation of the ISD pathway, but the DNA sensors that detect the endogenous DNA that accumulates in Trex1 (-/-) mice have not been defined. Multiple DNA sensors have been proposed to activate the ISD pathway, including cyclic GMP-AMP synthase (cGAS). In this study, we show that Trex1 (-/-) mice lacking cGAS are completely protected from lethality, exhibit dramatically reduced tissue inflammation, and fail to develop autoantibodies. These findings implicate cGAS as a key driver of autoimmune disease and suggest that cGAS inhibitors may be useful therapeutics for Aicardi-Goutières syndrome and related autoimmune diseases.

    Full Text Available Parmi les différentes déclinaisons du terme "frontière" (naturelle, politique, administrative, identitaire, existe-t-il une combinaison d'entre elles qui résisterait le plus farouchement à l'épreuve du temps? Le cas de la France qui, au sein de l'Europe, connaît une exception administrative particulière, est intéressant à observer. Ses nombreuses frontières intérieures ont repoussé avec obstination toute tentative de réduction de leur nombre. Sans doute parce que, laissée à l'initiative des populations locales et respectée par les successifs gouvernements, la définition des territoires s'est appuyée sur la reconnaissance des identités communales construites au cours des siècles par le quotidien des habitants. La correspondance cartographique établie entre le tissu paroissial du XVIIIe siècle en France, et le maillage communal d'aujourd'hui illustre, en dépit des quelques variations observées, la remarquable stabilité de ses frontières administratives.

    Le Roy Sylvestre

    2016-01-01

    Full Text Available This study, conducted on the city of Hyéres-les-Palmiers (French Riviera to guide the future land use planning, aimed to evaluate how sea level rise could modify coastal flooding hazards in urban areas located near small estuaries in a microtidal context. A joint probability approach allowed establishing typical storm parameters for specific return periods (30, 50 and 100 years, integrating offshore conditions (sea level and significant wave height and the river level. Storm scenarios have been established from these parameters and the chronology of the most impacting recent storm. Sea level rise has been integrated (20 cm for year 2030 and 60 cm for year 2100, and the coastal flooding has been simulated with a non-hydrostatic non-linear shallow-water model (SWASH. The calculations have been realized on high resolution DEM (1 to 5 m mesh size, integrating buildings and coastal protections. The approach has been validated by reproducing a recent flooding event. Obtained results show the importance of wave overtopping in current coastal flooding hazard in this area. Nevertheless, if Hyéres-les-Palmiers is currently little exposed to coastal flooding, these simulations highlight an increasing role of overflowing due to sea level rise, leading to significant flooding in 2100, even for quite frequent events.
