    Full Text Available As the context of Virg., Aen. VI 565 requires, the ancient interpretation of this line is correct, while the current consensus is mistaken. The Sibyl has never seen Tartarus. Subsequently, when she repeatedly asserts that she has witnessed the punishment of criminals confined in Tartarus, this blatant contradiction imitates the famously contradictory location of Odysseus outside Hades initially but later firmly within it.

  2. Relationship between surface structure of silicon containing steel and adhesion of hot dip galvanized coating; Si gan'yu koban no hyomen kozo to yoyu aen mekki micchakuseino kankei

    The surface of the annealed steel and the exfoliated interface of the coating for the hot dip galvanized Si containing steel sheets was characterized by using SEM (Scanning Electron Microscope), AES (Auger Electron Spectroscopy) and TEM (Transmission Electron Microscopy). The adhesion of the coatings have depended on the Si content of the steel. It have been found that MnSiO{sub 3} particles are formed at the surface of the annealed steels having high Si content and that two types of grain having different distribution of the oxide exist in the steels. Large oxide particles have been formed in one type of grain and small particles are formed in the other type of grain. The different type of Fe-Zn alloy are formed on two types of grains. It have been observed that the oxide particles exist at the interface of exfoliated coatings after the adhesion test for the steels with high Si content. The distribution of the oxide particles observed at the bottom of the exfoliated coating is quite similar to that of the surface oxide of the annealed steel. From these results, the exfoliation of the coating has initiated at the oxide particles of the steel surface that has been not reduced during the hot dip galvanizing. (author)

    Some of more important electrolytic solutions for Al electrodeposition are organic solvents, high-temperature type molten salts and low-temperature type molten salts having a melting point of 30{degree}C or lower, such as ethylmethylimidazolium chloride (EMIC). This study uses a molten salt of AlCl3-EMIC as the low-temperature type solution for high-speed electrodeposition. Discussed herein are the effects of melt temperature on limiting current density in Al electrodeposition and Al electrodeposit morphology. Limiting current density increases as melt temperature increases at any AlCl3 concentration used in this study. The AlCl3 concentration that gives the maximum limiting current density shifts from 64 to 67mol% at a melt temperature of 120{degree}C. A dense, smooth Al electrodeposited film results at a melt temperature of 100{degree}C or lower, but the electrodeposited grains become coarser as melt temperature increases. Melt temperature can be increased to 140{degree}C to secure a smooth electrodeposited film, showing possibility of 2 times faster electrodeposition than the conventional one. 21 refs., 12 figs., 1 tab.

    In order to make alkaline manganese batteries mercury-free and suppress hydrogen gas generation, investigations were given on the effect of additive species on modification of zinc particles present on negative electrode surface. Mercury with high hydrogen overvoltage has been added conventionally, but the mercury can cause an environmental problem. Surface modification by using indium exhibited hydrogen gas generation suppressing effect. With the surface modification amount of 0.10% by weight or more, the suppressing effect is saturated, reducing the effect to 50% of that of mercury. Surface-modifying the bismuth added zinc particles with indium showed greater suppressing effect than the case where each element is used independently. Zinc-indium (0.10% by weight) - bismuth (0.025% by weight) based alloy powder showed the same hydrogen generation suppressing effect as zinc-mercury (0.15% by weight) alloy powder. A sealed test battery using this alloy powder in negative active material exhibited a discharge capacity of 1700 mAh similarly to the initial stage even after having been stored for 20 days at 60 degC. Self-discharge characteristics equivalent to that of zinc-mercury (0.15% by weight) based alloy powder were obtained. An environment compatible dry cell battery containing no mercury whatsoever was developed successfully. 18 refs., 6 figs., 1 tab.

    Corrosion behavior of hot-dip Zn-6%Al 0-3%Mg alloy coated steel sheets in cyclic corrosion test (CCT) has been investigated. The corrosion resistance was improved with increasing Mg content in the coating layer, and the highest corrosion resistance was observed at 3% Mg. In Zn-6%Al-3%Mg alloy coated steel sheet, the formations of zinc carbonate hydroxide and zinc oxide were suppressed for longer duration compared with Zn-0.2%Al and Zn-4.5%Al-0.l%Mg alloy coated steel sheets. As a result, zinc chloride hydroxide existed stable on the surface of the coating layer. From the polarization behaviors in 5% NaCl aqueous solution after CCT, it was found that the corrosion current density of Zn-6%At-3%Mg alloy coated steel sheet was much smaller than those of Zn-0.2%Al and Zn-4.5%Al-0.1%Mg alloy coated steel sheets. As zinc carbonate hydroxide and zinc oxide had poor adhesion to the coating layer and had porous structures, these corrosion products were considered to have little protective action for the coating layer. Therefore, it was concluded that Mg suppressed the formation of such nonprotective corrosion products. resulting in the remarkable improvement of corrosion resistance. (author)

  7. Devices for separation of particle emissions from biofuel plants smaller than 10 MW - Today's technology and potential for development; Stoftreningsteknik foer biobraensleanlaeggningar mindre aen 10 MW - tekniklaege och utvecklingspotential

    The objective of this report is to compile a survey of available technologies for separation of particles and to present research and development in the area of particle separation for biofuel plants smaller than 10 MW. Technical and economical opportunities to transfer the technologies used today in larger plants to smaller ones are discussed. As the health effects of aerosols are under investigation, the issue of separation of particle less than 1 {mu}m is especially scrutinised. Current research concerning the particle size distribution at different load is presented. The project has been realised partly as a literature survey, partly through contacts with scientists in the area and manufacturers of devices for flue gas cleaning and particle separation. The target group is owners of plants, manufacturers of devices and authorities with responsibility for air quality and energy planning. Fabric filters is an established technology that can perform low particle emissions (less than a few mg/m{sup 3}) at a low cost also at smaller plants. Also electrostatic precipitators can perform the same low emissions, but the cost for installation at smaller plants has to be reduced. Both these technologies can, properly designed, separate submicron particles. Cyclones can today as its best perform a little less than 100 mg/m{sup 3} at 13 % CO{sub 2}. Cyclones are used together with other technologies to achieve high separation at a low cost. Cyclones are attractive because of their simplicity and low price, but because they use inertia forces as separation mechanism, they can never separate submicron particles. Conventional scrubbers and flue gas condensers are capable of separation of submicron particles but the efficiency is lower compared with fabric filters and electrostatic precipitators. The emission level after a scrubber/flue gas condenser is about 70 - 80 mg/m{sup 3} at 13 % CO{sub 2}. New technologies for separation of particles oriented towards smaller plants and towards separation of smaller particles are beds filled with gravel or granulate for ionised flue gas, found installed in Sweden and in a research plant in Denmark. In Germany a combined cyclone/fabric filter/catalytic converter is developed, with the requested ability to separate submicron particles. In Norway a panel bed filter has been tested, working on the same principle as a fabric filter showing good abilities to separate submicron particles. It is uncertain if any of these mentioned new technologies will show to be competitive besides the already established ones. The knowledge of how particles are formed, how load and operation of the specific plant influence on the formation, how the particles are distributed in size and mass and their chemical composition, is limited. To meet the demand for good air quality at the same time as combustion of biofuel in small scale plants is increased, there is a need for more research and more measurements to cast light on both mechanisms for formation and separation. Possibilities have to be given to realise new ideas and to test them in practise.

    Full Text Available Traditionally it is said that the source of Seneca's tragedies is Euripides. The coincidence with the subjects corroborates it. However, the nearness between tragedy and epic, the Trojan cycle that the first Latin writers of tragedy take for themselves, and, above all, the poetics of artistic effect based on the narrative structure and the lexical and syntactic patterns show that, at least in this passage, Seneca's source is Vergil, who is also the receiver and transmitter of ancient epic and the Greek and Roman tragedy.

    In this research, the seeds provided by Technology Research Institute of Osaka Prefecture and Nomura Plating Co., Ltd., relative to their plating processes using ion exchange membranes and metal anodes are utilized. Efforts are made to prolong the bathing life of the Ni-W alloy plating solution, to put the plating bath in an enclosure, to develop a chromium-free plating technology wherewith bating life is longer, environmental impact is smaller, and resistance to corrosion is higher, and experiments and tests are conducted for industrialization and for the practical application of the developed technologies. At Technology Research Institute of Osaka Prefecture, electrolytic Ni-W alloy plating was taken up. An insoluble anode separated from the plating solution by a cation exchange membrane and plural metal anodes were brought into a new process and, into the same, novel technologies were further introduced, which were a metal ion supply method in which the distribution of current to 3 anodes was regulated and the employment of a sacrificial anode decomposition agent. The new process was investigated for its validity and difficulties. Furthermore, Ni-W-P alloy plating was studied and a mirror-like Ni-W-P alloy plate was developed in a phosphorous acid added bath without detriment to the non-waste solution plating process, and the plate exhibited high corrosion resistance in a CASS (copper-accelerated acetic acid salt spray) test.

    The R and D project has been implemented for treating metal plating wastes (sludge) and aluminum dross in a melting furnace operated in a reducing atmosphere, in order to make the wastes harmless and recover the rare metals by the thermit reactions. The theoretical analysis of the powder properties has produced the desired powder pretreatment conditions, such as drying/firing conditions, mixing ratio and composition, forming conditions, and characteristics of the formed articles. For recovering the useful metals, it is confirmed that the thermit reactions proceed efficiently in a high-temperature melting furnace operated in a reducing atmosphere, and the molten metals are easily separated from the molten slag. It is also confirmed that the formed article allows separation of the metals from the residual slag more easily than the mixed powder. For the design of the continuous thermit reaction (CTR) system, it is investigated whether the products and other discharged substances can be safely handled and effectively utilized, and the control/instrumentation systems and others are established after setting the conditions for, e.g., sludge drying/firing in air, powder mixing/crushing, briquette production, and flow of the thermit reactions in a reducing atmosphere.

    Concerning the above, it is discussed whether such a system is feasible in Japan. A zinc/air cell system requires some special plants for zinc regeneration, etc. It is necessary to build a zinc refining plant and to install dozens of electrode replacing facilities in an area dozens of kilometers in diameter with the plant at the center. For such a system to be functional, there have to be several tens of thousands of automobile users in a limited area. In Japan, so large a number will not be found anywhere even if the appeal is directed to those in the postal service and electric utilities. There will be no economic success in Japan, different from in Germany. As for the economic comparison between a zinc/air cell system and natural gas system, the two will be equivalent to each other as far as the use of the quick filling stations for the natural gas automobiles remains as it is. When the number in consideration is so large as several tens of thousands, however, the natural gas system will turn out to be economically superior to the zinc/air cell system. 19 figs., 29 tabs.

    Improving nitrogen use efficiency (NUE) in the major cereals is critical for more sustainable nitrogen use in high-input agriculture, but our understanding of the potential for NUE improvement is limited by a paucity of reliable on-farm measurements. Limited on-farm data suggest that agronomic NUE (AE(N)) is lower and more variable than data from trials conducted at research stations, on which much of our understanding of AE(N) has been built. The purpose of this study was to determine the magnitude and causes of variability in AE(N) across an agricultural region, which we refer to as the achievement distribution of AE(N). The distribution of simulated AE(N) in 80 farmers' fields in an irrigated wheat system in the Yaqui Valley, Mexico, was compared with trials at a local research center (International Wheat and Maize Improvement Center; CIMMYT). An agroecosystem simulation model WNMM was used to understand factors controlling yield, AE(N), gaseous N emissions, and nitrate leaching in the region. Simulated AE(N) in the Yaqui Valley was highly variable, and mean on-farm AE(N) was 44% lower than trials with similar fertilization rates at CIMMYT. Variability in residual N supply was the most important factor determining simulated AE(N). Better split applications of N fertilizer led to almost a doubling of AE(N), increased profit, and reduced N pollution, and even larger improvements were possible with technologies that allow for direct measurement of soil N supply and plant N demand, such as site-specific nitrogen management.

    Studies demonstrated that chronic high-dose homocysteine administration induced learning and memory impairment in animals. Atractylenolide III (Aen-III), a neuroprotective constituent of Atractylodis macrocephalae Koidz, was isolated in our previous study. In this study, we investigated potential benefits of Aen-III in preventing learning and memory impairment following chronic high-dose homocysteine administration in rats. Results showed that administration of Aen-III significantly ameliorated learning and memory impairment induced by chronic high-dose homocysteine administration in rats, decreased homocysteine-induced reactive oxygen species (ROS) formation and restored homocysteine-induced decrease of phosphorylated protein kinase C expression level. Moreover, Aen-III protected primary cultured neurons from apoptotic death induced by homocysteine treatment. This study provides the first evidence for the neuroprotective effect of Aen-III in preventing learning and impairment induced by chronic administration of homocysteine. Aen-III may have therapeutic potential in treating homocysteine-mediated cognitive impairment and neuronal injury. Copyright © 2015 IBRO. Published by Elsevier Ltd. All rights reserved.

    Full Text Available ABSTRACT The application of beneficial bacteria has recently been used for sustainable agriculture. In current research, 71 bacterial isolates were obtained from rice plant and the rhizosphere soil of different paddy fields in Guilan province, Iran. After primitive investigation, 40 bacteria with typical predominant characteristics were selected. By PCR-RFLP of their 16S r-DNA gene, 8 Operational Taxonomic Units (OTUs totally consisted of 33 isolates were obtained. From all of them, 8 isolates were selected for rice seed germination experiment, then, effective isolates were used for pot experiment to evaluate their ability for promoting rice growth. All of them were able to increase rice growth and yield, but in different potential. These tested isolates were identified as Alcaligenes faecalis (DEp8, O1R4, Pantoea ananatis (AEn1, Bacillus vietnamensis (MR5, Bacillus idriensis (MR2 and Stenotrophomonas maltophilia by partial sequencing of their 16S r-DNA gene. Among them, AEn1 and MR5 produced indole-3- acetic acid (IAA in larger amounts than the other isolates and the isolates AEn1 and O1R4 were able to solubilize phosphate in higher amounts. According to the results obtained, it can be concluded that AEn1, O1R4 and MR5 can be considered as bacterial inoculants to use as alternatives for chemical fertilizers.

    The chronic use of organic nitrates is limited by serious side effects including oxidative stress, nitrate tolerance and/or endothelial dysfunction. The side effects and potency of nitroglycerine depend on mitochondrial aldehyde dehydrogenase (ALDH-2). We sought to determine whether this concept can be extended to a new class of organic nitrates with amino moieties (aminoalkyl nitrates). Vasodilator potency of the organic nitrates, in vitro tolerance and in vivo tolerance (after continuous infusion for 3 days) were assessed in wild-type and ALDH-2 knockout mice by isometric tension studies. Mitochondrial oxidative stress was analysed by L-012-dependent chemiluminescence and protein tyrosine nitration. Aminoethyl nitrate (AEN) showed an almost similar potency to glyceryl trinitrate (GTN), even though it is only a mononitrate. AEN-dependent vasodilatation was mediated by cGMP and nitric oxide. In contrast to triethanolamine trinitrate (TEAN) and GTN, AEN bioactivation did not depend on ALDH-2 and caused no in vitro tolerance. In vivo treatment with TEAN and GTN, but not with AEN, induced cross-tolerance to acetylcholine (ACh)-dependent and GTN-dependent relaxation. Although all nitrates tested induced tolerance to themselves, only TEAN and GTN significantly increased mitochondrial oxidative stress in vitro and in vivo. The present results demonstrate that not all high potency nitrates are bioactivated by ALDH-2 and that high potency of a given nitrate is not necessarily associated with induction of oxidative stress or nitrate tolerance. Obviously, there are distinct pathways for bioactivation of organic nitrates, which for AEN may involve xanthine oxidoreductase rather than P450 enzymes.

  4. Blogging Bouazizi: The Role of Cyberactivists Before and After Tunisia’s Jasmine Revolution

    Full Text Available This article examines the changing role of cyberactivists before and after the Jasmine Revolution through case studies of three prominent figures: Houssem Aoudi (Cogite, Wasaibi, Sami Ben Gharbia (Nawaat.org, and Haythem el Mekki (MosaiqueFM, Attessia TV. The main argument presented here is that the attainment of freedom of the Internet and the success of the revolt created new opportunities for formal political involvement for the cyberactivists as they transited from dissidents under the Ben Ali regime to citizen-participants of a nascent democratic order. A subsidiary argument is that a new generation of Tunisian leadership came to the fore of Tunisia’s private and public spheres to advance the stated aims of the revolution, including inter alia combating unemployment, securing civil liberties, stemming corruption, and the ever deepening of pro-democracy reforms.

    This study investigates the suitability of the asynchronous ensemble Kalman filter (AEnKF) and a partitioned updating scheme for hydrological forecasting. The AEnKF requires forward integration of the model for the analysis and enables assimilation of current and past observations simultaneously at a single analysis step. The results of discharge assimilation into a grid-based hydrological model (using a soil moisture error model) for the Upper Ourthe catchment in the Belgian Ardennes show that including past predictions and observations in the data assimilation method improves the model forecasts. Additionally, we show that elimination of the strongly non-linear relation between the soil moisture storage and assimilated discharge observations from the model update becomes beneficial for improved operational forecasting, which is evaluated using several validation measures.

    It has been hypothesized that a high reproductive output contributes to the unique gigantism in large dinosaur taxa. In order to infer more information on dinosaur reproduction, we established allometries between body mass and different reproductive traits (egg mass, clutch mass, annual clutch mass) for extant phylogenetic brackets (birds, crocodiles and tortoises) of extinct non-avian dinosaurs. Allometries were applied to nine non-avian dinosaur taxa (theropods, hadrosaurs, and sauropodomorphs) for which fossil estimates on relevant traits are currently available. We found that the reproductive traits of most dinosaurs conformed to similar-sized or scaled-up extant reptiles or birds. The reproductive traits of theropods, which are considered more bird-like, were indeed consistent with birds, while the traits of sauropodomorphs conformed better to reptiles. Reproductive traits of hadrosaurs corresponded to both reptiles and birds. Excluding Massospondylus carinatus , all dinosaurs studied had an intermediary egg to body mass relationship to reptiles and birds. In contrast, dinosaur clutch masses fitted with either the masses predicted from allometries of birds (theropods) or to the masses of reptiles (all other taxa). Theropods studied had probably one clutch per year. For sauropodomorphs and hadrosaurs, more than one clutch per year was predicted. Contrary to current hypotheses, large dinosaurs did not have exceptionally high annual egg numbers (AEN). Independent of the extant model, the estimated dinosaur AEN did not exceed 850 eggs (75,000 kg sauropod) for any of the taxa studied. This estimated maximum is probably an overestimation due to unrealistic assumptions. According to most AEN estimations, the dinosaurs studied laid less than 200 eggs per year. Only some AEN estimates obtained for medium to large sized sauropods were higher (200-400 eggs). Our results provide new (testable) hypotheses, especially for reproductive traits that are insufficiently

    Full Text Available The aim of this study was to evaluate the initial growth, nitrogen (N uptake, and agronomic efficiency after the use of N fertilizers in upland rice cultivation. The experiment was conducted in a greenhouse by using pots filled with surface-layer (0 to 20 cm soil collected from the municipality of Jaguapitã, Paraná. The experimental design was completely randomized with 4 replications. A factorial scheme of 5 × 2 was used, in which the factors were 5 N rates (0, 25, 50, 75, and 100 kg ha-1 N and 2 cultivars of rice (Fedearroz Lagunas [Colombian] and IAPAR- 9 [Brazilian]. The N sources tested were ammonium sulfate (Experiment I and calcium nitrate (Experiment II. The following variables were evaluated: number of tillers per pot (NTP, dry mass of the shoots (DMS, N content in the dry mass (NCDM, and agronomic efficiency of N fertilizer (AEN. The data obtained in the experiments were evaluated using analysis of variance, and mean values were compared using Tukey’s test at 5% significance for rice cultivar effects or adjusted to polynomial regression equations for N rates. Use of calcium nitrate yielded higher values of NTP, NCDM, and AEN. The cultivar Lagunas showed higher NTP, while IAPAR-9 showed higher DMS. An increase in N rates, for both sources, resulted in the increase of NTP, DMS, and NCDM; however, AEN was decreased.

  15. An Adjoint-Based Adaptive Ensemble Kalman Filter

    KAUST Repository

    Song, Hajoon

    2013-10-01

    A new hybrid ensemble Kalman filter/four-dimensional variational data assimilation (EnKF/4D-VAR) approach is introduced to mitigate background covariance limitations in the EnKF. The work is based on the adaptive EnKF (AEnKF) method, which bears a strong resemblance to the hybrid EnKF/three-dimensional variational data assimilation (3D-VAR) method. In the AEnKF, the representativeness of the EnKF ensemble is regularly enhanced with new members generated after back projection of the EnKF analysis residuals to state space using a 3D-VAR [or optimal interpolation (OI)] scheme with a preselected background covariance matrix. The idea here is to reformulate the transformation of the residuals as a 4D-VAR problem, constraining the new member with model dynamics and the previous observations. This should provide more information for the estimation of the new member and reduce dependence of the AEnKF on the assumed stationary background covariance matrix. This is done by integrating the analysis residuals backward in time with the adjoint model. Numerical experiments are performed with the Lorenz-96 model under different scenarios to test the new approach and to evaluate its performance with respect to the EnKF and the hybrid EnKF/3D-VAR. The new method leads to the least root-mean-square estimation errors as long as the linear assumption guaranteeing the stability of the adjoint model holds. It is also found to be less sensitive to choices of the assimilation system inputs and parameters.

    ASN strives to share practices with its foreign counterparts in order to develop and adopt best practice worldwide. With regard to inspection practices, the exchanges are made with AEN, in particular within the context of the Working Group on Inspection Practices (WGIP). As well as being very rewarding, the exchanges sometimes come up against marked differences in terms of inspection organisation and even in the meaning given to the inspections. The WGIP endeavors, however, to make inspection practice recommendations that are as functional and feasible as possible. (author)

    2009-01-01

    The luminescence properties of Tb 3+ and Eu 3+ dissolved in ionic liquids are studied. Solutes in this study include simple lanthanide compounds (e.g., EuBr 3 , TbCl 3 ) and lanthanide complexes (e.g., Eu(dpa) 3 3- where dpa = 2,6 pyridine dicarboxylate dianion) dissolved in a 1-butyl-3-methylimidazolium bromide(BMIBr)/water mixture. Emission, excitation, and time-resolved emission measurements are utilized to characterize the spectroscopic properties. It is well established in the literature that the solubility and spectroscopic properties of lanthanides in ionic liquids are highly dependent upon environmental factors including purity, and water content [K. Binnemans, Chemical Reviews (2007); I. Billard, S. Mekki, C. Gaillard, P. Hesemann, C. Mariet, G. Moutiers, A. Labet, J.-C.G. Buenzli, European Journal of Inorganic Chemistry 6 (2004) 1190-1197; S. Samikkanu, K. Mellem, M. Berry, P.S. May, Inorganic Chemistry 46 (2007) 7121-7128]. The water in this ionic liquid system acts as a co-solvent to facilitate solubility of Tb 3+ and Eu 3+ compounds. The observed spectroscopic properties of Eu 3+ and Tb 3+ salts are expectedly impacted by the high water content, but unexpectedly impacted by the BMIBr ionic liquid. However, the spectroscopy of Eu(dpa) 3 3- is unaffected by the presence of BMIBr.

    Full Text Available The high oxidative stability of virgin olive oil is related to its high monounsaturated/polyunsaturated ratio and to the presence of antioxidant compounds, such as tocopherols and phenols. In this paper, the isolation of phenolic compounds from virgin olive oil from several Algerian varieties was tested and discussed in order to know its potential uses and benefits. Quantification of phenolic and o-diphenolic substances was performed using the traditional Folin-Ciocalteau method and the sodium molybdate reaction, respectively. The qualitative and quantitative characterizations of phenolic compounds were carried out by HPLC. The experimental results show that tyrosol, hydroxytyrosol and 4-HBA (4-hydroxybenzoic acid are the main individual phenolic compounds identified in the varieties studied. The varieties with large fruits (Grosse du Hamma, Aghenfas, Azeradj, Aguenaou, Aberkane, Bouchouk de Guergour, X-Aghenfas, Rougette de Guelma, Sigoise are clearly distinguished from the varieties with medium-sized and small fruits by having the highest levels of individual phenolic compounds. Moreover, varieties with small fruits (Hamra, Chemlal, Boughenfas, Limli, Aimel and Mekki presented the highest levels of oleuropein.La alta estabilidad oxidativa de los aceites de oliva vírgenes está relacionada con su alta relación de ácidos grasos monoinsaturados/poliinsaturados y con la presencia de componentes antioxidantes, como tocoferoles y polifenoles.

    The problem of waste management has gained relevance with the development of electronuclear production and the increased social awareness on the need to protect the environment. While most developed countries have found solutions for the disposal of waste of low intensity and duration, the storage of used fuel and other kind of waste of higher intensity and duration is one of the main challenges for the next decade. Scientific research focuses on long term safety, while questions on the need for new governance are raised at the socio political level. Organizations such as the AEN have strengthened international cooperation to overcome the scientific, technical and socio-political challenges related to the nuclear waste management.

    Mass attenuation coefficients of amino acids such as n-acetyl-l-tryptophan, n-acetyl-l-tyrosine and d-tryptophan were measured in the energy range 0.122-1.330 MeV. NaI (Tl) scintillation detection system was used to detect gamma rays with a resolution of 8.2% at 0.662 MeV. The measured attenuation coefficient values were then used to determine the mass energy-absorption coefficients (σ{sub a,en}) and average atomic energy-absorption cross sections (μ{sub en}/ρ) of the amino acids. Theoretical values were calculated based on XCOM data. Theoretical and experimental values are found to be in good agreement.

    Highlights: • Stochastic model is proposed for coordinated scheduling of renewable energy sources. • The effect of combined heat and power is considered. • Uncertainties of wind speed, solar radiation and electricity market price are considered. • Profit maximization, emission and AENS minimization are considered as objective functions. • Modified firefly algorithm is employed to solve the problem. - Abstract: Nowadays the operation of renewable energy sources and combined heat and power (CHP) units is increased in micro grids; therefore, to reach optimal performance, optimal scheduling of these units is required. In this regard, in this paper a micro grid consisting of proton exchange membrane fuel cell-combined heat and power (PEMFC-CHP), wind turbines (WT) and photovoltaic (PV) units, is modeled to determine the optimal scheduling state of these units by considering uncertain behavior of renewable energy resources. For this purpose, a scenario-based method is used for modeling the uncertainties of electrical market price, the wind speed, and solar irradiance. It should be noted that the hydrogen storage strategy is also applied in this study for PEMFC-CHP units. Market profit, total emission production, and average energy not supplied (AENS) are the objective functions considered in this paper simultaneously. Consideration of the above-mentioned objective functions converts the proposed problem to a mixed integer nonlinear programming. To solve this problem, a multi-objective firefly algorithm is used. The uncertainties of parameters convert the mixed integer nonlinear programming problem to a stochastic mixed integer nonlinear programming problem. Moreover, optimal coordinated scheduling of renewable energy resources and thermal units in micro-grids improve the value of the objective functions. Simulation results obtained from a modified 33-bus distributed network as a micro grid illustrates the effectiveness of the proposed method.

    Hydrological forecasts can be made more reliable and less uncertain by recursively improving initial conditions. A common way of improving the initial conditions is to make use of data assimilation (DA), a feedback mechanism or update methodology which merges model estimates with available real world observations. The traditional implementation of the Ensemble Kalman Filter (EnKF; e.g. Evensen, 2009) is synchronous, commonly named a three dimensional (3-D) assimilation, which means that all assimilated observations correspond to the time of update. Asynchronous DA, also called four dimensional (4-D) assimilation, refers to an updating methodology, in which observations being assimilated into the model originate from times different to the time of update (Evensen, 2009; Sakov 2010). This study investigates how the capabilities of the DA procedure can be improved by applying alternative Kalman-type methods, e.g., the Asynchronous Ensemble Kalman Filter (AEnKF). The AEnKF assimilates observations with smaller computational costs than the original EnKF, which is beneficial for operational purposes. The results of discharge assimilation into a grid-based hydrological model for the Upper Ourthe catchment in Belgian Ardennes show that including past predictions and observations in the AEnKF improves the model forecasts as compared to the traditional EnKF. Additionally we show that elimination of the strongly non-linear relation between the soil moisture storage and assimilated discharge observations from the model update becomes beneficial for an improved operational forecasting, which is evaluated using several validation measures. In the current study we employed the HBV-96 model built within a recently developed open source modelling environment OpenStreams (2013). The advantage of using OpenStreams (2013) is that it enables direct communication with OpenDA (2013), an open source data assimilation toolbox. OpenDA provides a number of algorithms for model calibration

    Full Text Available In order to make clear the recent status and trend of wheat (Triticum aestivum L. production in China, datasets from multiple field experiments and published literature were collected to study the agronomic characteristics related to grain yield, fertilizer application and nutrient use efficiency from the year 2000 to 2011. The results showed that the mean grain yield of wheat in 2000-2011 was 5950 kg/ha, while the N, P2O5 and K2O application rates were 172, 102 and 91 kg/ha on average, respectively. The decrease in N and P2O5 and increase in K2O balanced the nutrient supply and was the main reason for yield increase. The partial factor productivity (PFP, kg grain yield produced per unit of N, P2O5 or K2O applied values of N (PFP-N, P (PFP-P and K (PFP-K were in the ranges of 29.5~39.6, 43.4~74.9 and 44.1~76.5 kg/kg, respectively. While PFP-N showed no significant changes from 2000 to 2010, both PFP-P and PFP-K showed an increased trend over this period. The mean agronomic efficiency (AE, kg grain yield increased per unit of N, P2O5 or K2O applied values of N (AEN, P (AEP and K (AEK were 9.4, 10.2 and 6.5 kg/kg, respectively. The AE values demonstrated marked inter-annual fluctuations, with the amplitude of fluctuation for AEN greater than those for AEP and AEK. The mean fertilizer recovery efficiency (RE, the fraction of nutrient uptake in aboveground plant dry matter to the nutrient of fertilizer application values of N, P and K in the aboveground biomass were 33.1%, 24.3% and 28.4%, respectively. It was also revealed that different wheat ecological regions differ greatly in wheat productivity, fertilizer application and nutrient use efficiency. In summary, it was suggested that best nutrient management practices, i.e. fertilizer recommendation applied based on soil testing or yield response, with strategies to match the nutrient input with realistic yield and demand, or provided with the 4R's nutrient management (right time, right rate, right

    The Adomian decomposition method (ADM) is one of the most effective methods to construct analytic approximate solutions for nonlinear differential equations. In this paper, based on the new definition of the Adomian polynomials, Rach (2008) [22], the Adomian decomposition method and the Padé approximants technique, a new algorithm is proposed to construct analytic approximate solutions for nonlinear fractional differential equations with initial or boundary conditions. Furthermore, a MAPLE software package is developed to implement this new algorithm, which is user-friendly and efficient. One only needs to input the system equation, initial or boundary conditions and several necessary parameters, then our package will automatically deliver the analytic approximate solutions within a few seconds. Several different types of examples are given to illustrate the scope and demonstrate the validity of our package, especially for non-smooth initial value problems. Our package provides a helpful and easy-to-use tool in science and engineering simulations.

    Climate variability impacts agricultural processes through many mechanisms. For example, the proliferation of pests and diseases increases with warmer climate and alternated wind patterns, as longer growing seasons allow pest species to complete more reproductive cycles and changes in the weather patterns alter the stages and rates of development of pests and pathogens. Several studies suggest that enhancing plant diversity and complexity in farming systems, such as in agroforestry systems, reduces the vulnerability of farms to extreme climatic events. On the other hand, other authors have argued that vegetation diversity does not necessarily reduce the incidence of pests and diseases, highlighting the importance of understanding how, where and when it is recommendable to diversify vegetation to improve pest and disease control, and emphasising the need for tools to develop, monitor and evaluate agroecosystems. In order to understand how biodiversity can enhance ecosystem services provided by the agroecosystem in the context of climatic variability, it is important to develop comprehensive models that include the role of trophic chains in the regulation of pests, which can be achieved by integrating crop models with pest-predator models, also known as agroecosystem network (AEN) models. Here we present a methodology for the participatory data collection and monitoring necessary for running Tiko'n, an AEN model that can also be coupled to a crop model such as DSSAT. This methodology aims to combine the local and practical knowledge of farmers with the scientific knowledge of entomologists and agronomists, allowing for the simplification of complex ecological networks of plant and insect interactions. This also increases the acceptability, credibility, and comprehension of the model by farmers, allowing them to understand their relationship with the local agroecosystem and their potential to use key agroecosystem principles such as functional diversity to mitigate

    About 10 years ago, after the Sarin attack in Tokyo, the world discover that terrorists could use again radio-nuclear, chemical or biological agents to launch attacks, just to cause terror and disruption of western economies. This has forged the acronym 'NRBC'. In terms of likelihood, nuclear and radiological attacks could be considered among the most easy to prepare, and some possible acts are listed in this paper. A considerable amount of work has been prepared for the preparedness against radio-nuclear attacks, during the last 3 years, by World Health Organization (WHO), International Atomic Energy Agency (IAEA), the Atomic Energy Agency (AEN) as well as by the International Commission of Radio Protection (ICRP). A series of documents have been issued from international cooperation. These documents shows specificities to the R/N threat in terms of health consequences, that make this threat less prone to international cooperative efforts than biological threats. In addition, the Ministers of Health of the G7 countries have created an 'Global Health Security Initiative' (GHSI) in 2002 to anticipate crisis such as the anthrax problem, or other possible NRBC threats

    The development of human limb is controlled by several transcription factors and signaling pathways, which are organized in precise time- and space-restricted manners. Recent studies showed that P63 and its signaling pathway play important roles in this process. Transcription factor P63, one member of the P53 family, is characterized by a similar amino acid domain, plays a crucial role in the development of limb and ectoderm differentiation, especially with its DNA binding domain, and sterile alpha motif domains. Mutated P63 gene may produce abnormal transcription factor P63 which can affect the signaling pathway. Furthermore, defective signaling protein in structure and/or quantity is synthesized though the pathway. Eventually, members of the signaling protein family are involved in the regulation of differentiation and development of stem cell, which causes deformity of limbs. In brief, three signaling pathways are related to the digit formation along three axes, including SHH-ZPA, FGFs-AER and Lmx1B-Wnt7a-En1. Each contains numerous signaling molecules which are integrated in self-regulatory modules that assure the acquisition or the correct digit complements. These finding has brought new clues for deciphering the etiology of congenital limb malformation and may provide alternatives for both prevention and treatment.

    In the frame of the collaborative program COST 538 a coating life prediction code was implemented by Proing and ERSE with an inverse problem solution routine able to calculate the local mean operating temperature from the operating conditions and the extension of the coating depleted regions. Moreover base material degradation models were developed by Ansaldo Energia on both equiaxed and single crystal superalloys. This paper describes the application of such methodologies to two ex-service 1st stage gas turbine blades delivered to COST 538 by AEN after operation in two different plants with different operating conditions. The objective of the study was the application and validation of an innovative NDT and the estimate of the mean operating temperature at different positions of the components. The destructive metallographic analysis of the blades let to validate the non destructive frequency scanning eddy current technique (F-SECT). Coating life modelling results are compared with those of the base material degradation models. An interesting correlation was found between the estimated temperatures with the two methods and also with the NDT findings at the most significant component positions. (orig.)

    Since issuing its latest basic recommendations in 1991 as ICRP Publication 60, the Commission has reviewed these recommendations regularly and, from time to time, has issued supplementary reports in the Annals of the ICRP. The extent of these supplementary reports has indicated a need for consolidation and rationalization. New scientific data have also been published since Publication 60, and while the biological and physical assumptions and concepts remain robust, some updating is required. In addition, there have been societal developments in that more emphasis is now given on the protection of individuals and stakeholder involvement in the management of radiological risk. Finally, it has also become apparent that the radiological protection of non-human species should receive more emphasis than in the past. It is against this background that the Commission has now decided to adopt a revised set of Recommendations while at the same time maintaining stability with the previous recommendations. Following several years of an open and worldwide discussion process, mainly through web consultation, ICRP intends to publish its new recommendations in 2007. In the context of AEN/NEA seminar on safety case for the deep disposal of radioactive waste, it appeared necessary first of all to examine the above mentioned evolution of ICRP system, as well as to recall the main ICRP publications on potential exposure and waste disposal and finally to focus on the main recommendations on solid waste disposal which are still valid.

    Full Text Available The genus Luciobarbus in Morocco presents high diversification, in contrast to the generally impoverished freshwater fish fauna from North Africa. Within Morocco the northern area is one of the least studied territories, due to both its historical background and the limited accessibility of many regions. Previous phylogenetic studies identified Luciobarbus populations that are morphologically and genetically differentiated, to the same extent as others already recognized as separate species. The aim of this work is to describe these populations as distinct species, based on morphological, meristic, and genetic traits. urn:lsid:zoobank.org:pub:8FC4B423-104C-4097-A468-ED3D2664A15AEn Marruecos el género Luciobarbus está altamente diversificado, en comparación con la empobrecida fauna de peces de agua dulce del norte de África.

  10. Identification of Differential Gene Expression Patterns after Acute Exposure to High and Low Doses of Low-LET Ionizing Radiation in a Reconstituted Human Skin Tissue

    Our goal here was to identify dose and temporal dependent radiation responses in a complex tissue, reconstituted human skin. Direct sequencing of RNA (RNA-seq) was used to quantify altered transcripts following exposure to 0.1, 2 and 10 Gy of ionizing radiation at 3 and 8 hours. These doses include a low dose in the range of some medical diagnostic procedures (0.1 Gy), a dose typically received during radiotherapy (2.0 Gy) and a lethal dose (10 Gy). These doses could be received after an intentional or accidental radiation exposure and biomarkers are needed to rapidly and accurately triage exposed individuals. A total of 1701 genes were deemed to be significantly affected by high dose radiation exposure with the majority of genes affected at 10 Gy. A group of 29 genes including GDF15, BBC3, PPM1D, FDXR, GADD45A, MDM2, CDKN1A, TP53INP1, CYCSP27, SESN1, SESN2, PCNA, and AEN were similarly altered at both 2 and 10 Gy, but not 0.1 Gy, at multiple time points. A much larger group of up regulated genes, including those involved in inflammatory responses, was significantly altered only after a 10 Gy exposure. At high doses, down regulated genes were associated with cell cycle regulation and exhibited an apparent linear response between 2 and 10 Gy. While only a handful of genes were significantly affected by 0.1 Gy exposure using stringent statistical filters, groups of related genes regulating cell cycle progression and inflammatory responses consistently exhibited opposite trends in their regulation compared to the high dose exposures. Differential regulation of PLK1 signaling at low and high doses was confirmed using qRT-PCR. These results indicate that some alterations in gene expression are qualitatively different at low and high doses of radiation in this model system.

The review begins in1890 and ends in 1980, when the publication ofDSM-III evacuates every aetiological theory aboutthe hysterical condition, refusing thepsychoanalytic theory of hysteria, gettingthroughout such manual a fragmentation of thephenomenon in multiple disorders that occur in

    Full Text Available In our country, there are currently two types of psychologist qualified to practise psychology in the health field: the Specialist Psychologist in Clinical Psychology (PEPC and the General Health Psychologist (PGS. These qualifications are legally regulated and their accreditation is obtained through two different programs of postgraduate training: the Residential Internship Program (PIR in the case of the PEPC; and the Master of General Health Psychology (MPGS in the case of the PGS. These programs are of different lengths (4 years for the PIR and 2 years for the MPGS and they are accessed after completion of the corresponding degree in Psychology. However, the objectives and the skills to be attained, as well as the content of the training programs, are actually very similar, in spite of the different linguistic denominations used to describe them. On the basis of the existing differences in the terminology and the duration of the programs, some Spanish associations (ANPIR, COP, AEPCP and AEN defend the position that there should be established between the two qualifications, in addition to a hierarchical structure, a clear boundary with respect to the functions that the two types of psychologist can perform (clinical and specialised versus health and general functions and of the sectors or contexts in which they can practise (public versus private. In our article, we refute these positions and the reasons on which they are based and we argue extensively in favour of an alternative proposal more in tune with the reality of the facts and with the European context professional accreditation in clinical psychology, in the sense of accepting the existence of the two independent qualifications of clinical psychologists (the PEPC and the PGS, with direct access to both from the degree in Psychology, and with equivalent competencies and professional functions, although with some limitations in the case of the PGS, mainly with respect to the

    These technical days were organized by the Environment section of the French Society of Radiation Protection (SFRP). Time was given to some exchange about the societal aspects of radioactive waste management as well as about the legal context but the most part of the debates delt with the actual management modalities of the different types of wastes, both in France and in foreign countries, and with the related stakes, in particular in terms of impact. This document brings together the presentations (slides) of the following talks: - Contributions of radiation protection to the long-term safety management of radioactive wastes (Jean-Paul MINON - ONDRAF); - The national inventory of radioactive materials and wastes (Arnaud LECLAIRE - ANDRA); - The high activity, medium activity-long living wastes in debate - a co-building approach (ANCCLI/Clis of Bure/IRSN) to share stakes, enlighten, and develop thought (Ludivine GILLI - IRSN, Yves LHEUREUX - ANCCLI); - Social aspects of Radioactive Waste Management - The International Learning (Claudio PESCATORE - AEN/OCDE); - Citizens involvement and ACRO's point of view on radioactive wastes management (Pierre BARBEY - ACRO); - New CIPR recommendations about the geologic disposal of long-living radioactive wastes (Thierry SCHNEIDER - CEPN); - Overview of processes under the views of radiation protection principles (Didier GAY - IRSN); - The national plan of radioactive materials and wastes management (Loic TANGUY - ASN); - Joint convention on spent fuel management safety and on radioactive waste management safety - status and main stakes (Isabelle FOREST - ASN); - Transport of radioactive wastes (Bruno DESNOYERS - AREVA); - Optimisation and limitation of the environmental impacts of very-low level wastes - valorisation and processes selection (Michel PIERACCINI - EDF), Philippe PONCET - AREVA); - Management of hospital wastes - Example of Montpellier's University Regional Hospital (Bertille SEGUIN - CHRU de Montpellier); - Waste

    An operational streamflow forecasting testbed was implemented during the Intense Observing Period (IOP) of the Integrated Precipitation and Hydrology Experiment (IPHEx-IOP) in May-June 2014 to characterize flood predictability in complex terrain. Specifically, hydrological forecasts were issued daily for 12 headwater catchments in the Southern Appalachians using the Duke Coupled surface-groundwater Hydrology Model (DCHM) forced by hourly atmospheric fields and QPFs (Quantitative Precipitation Forecasts) produced by the NASA-Unified Weather Research and Forecasting (NU-WRF) model. Previous day hindcasts forced by radar-based QPEs (Quantitative Precipitation Estimates) were used to provide initial conditions for present day forecasts. This manuscript first describes the operational testbed framework and workflow during the IPHEx-IOP including a synthesis of results. Second, various data assimilation approaches are explored a posteriori (post-IOP) to improve operational (flash) flood forecasting. Although all flood events during the IOP were predicted by the IPHEx operational testbed with lead times of up to 6 h, significant errors of over- and, or under-prediction were identified that could be traced back to the QPFs and subgrid-scale variability of radar QPEs. To improve operational flood prediction, three data-merging strategies were pursued post-IOP: (1) the spatial patterns of QPFs were improved through assimilation of satellite-based microwave radiances into NU-WRF; (2) QPEs were improved by merging raingauge observations with ground-based radar observations using bias-correction methods to produce streamflow hindcasts and associated uncertainty envelope capturing the streamflow observations, and (3) river discharge observations were assimilated into the DCHM to improve streamflow forecasts using the Ensemble Kalman Filter (EnKF), the fixed-lag Ensemble Kalman Smoother (EnKS), and the Asynchronous EnKF (i.e. AEnKF) methods.

    Full Text Available El presente ensayo recupera las reflexiones y producciones del equipo interdisciplinario de investigadores y docentes de la Facultad de Trabajo Social (FTS de la Universidad Nacional de Entre Ríos (UNER, Argentina1. Nos proponemos por un lado revisar críticamente la noción de diversidad y las prácticas que en ella se fundan y por otra abordar la perspectiva de la producción social de la discapacidad desde el paradigma de la complejidad. Intentaremos deconstruir el concepto de diversidad, no para cambiarlo simplemente por otro que nos incomode menos, sino para sumergirnos en la maraña de sentidos en que la diversidad se inscribe como descriptor de un cierto orden de cosas. Entendemos que la noción de diversidad, en tanto descriptiva de un cierto cúmulo de tipos posibles es muy útil en el campo de lo biológico, pero sin duda es necesario discutir algunas implicancias de su traslado lineal al campo de lo social. Finalmente, proponemos pensar y pasar de la perspectiva de atención a/en la diversidad al abordaje en la complejidad recuperando la idea de experiencias de complejidad, en referencia a experiencias que ya no se organizan y legitiman en torno al señalamiento e identificación de tal o cual complejo (como un otro específico y/o su complejidad, sino experiencias capaces de reconocerla como condición intrínseca a toda experiencia pedagógica, social, política, cultural.This essay recovers ideas and productions of the interdisciplinary team of researchers and professors from the Faculty of Social Work at the National University of Entre Rios, Argentine.
