    To present the results achieved in the treatment of 1802 distal ureteral stones treated at the Lithotripsy Unit of the San Cecilio University Hospital over the last 10 years (1990-2000). Stones were treated by extracorporeal shock wave lithotripsy (ESWL) or ureteroscopy (URS). ESWL was the initial treatment in 81% of the cases (1460 calculi) and URS in the remaining 19% (342 stones). URS was performed for complication or failed ESWL (102 stones) and ESWL was performed for failed URS, basically due to stone migration (24 stones). Ureterolithotomy was required on 7 occasions. Sedation-analgesia with fentanyl and midazolam was routinely used in URS. Sedation was required in only 55% of the ESWL procedures. Elective ESWL resolved 93% of the cases, a percentage which is similar to that achieved with URS as first treatment. The ESWL retreatment rate was 1.3. URS was successful in 98% of the cases of failed ESWL. There are two treatment modalities for stones in the distal ureter: ESWL and URS. We advocate the use of outpatient URS with sedation preferably in the female patient, impacted stones, obstructive uropathy, stones larger than 2 cm and radiotransparent stones.

    2017-11-01

    Herein we outline a plausible proteome, encoded by assuming a primeval RNY genetic code. We unveil the primeval phenotype by using only the RNA genotype; it means that we recovered the most ancestral proteome, mostly made of the 8 amino acids encoded by RNY triplets. By looking at those fragments, it is noticeable that they are positioned, not at catalytic sites, but in the cofactor binding sites. It implies that the stabilization of a molecule appeared long before its catalytic activity, and therefore the Ur-proteome comprised a set of proteins modules that corresponded to Cofactor Stabilizing Binding Sites (CSBSs), which we call the primitive bindome. With our method, we reconstructed the structures of the "first protein modules" that Sobolevsky and Trifonov (2006) found by using only RMSD. We also examine the probable cofactors that bound to them. We discuss the notion of CSBSs as the first proteins modules in progenotes in the context of several proposals about the primitive forms of life.

    A nephritic colic is the clinical picture that evidences the presence of ureteral stones, the natural evolution being their spontaneous passing. Stones in the distal ureter are self-eliminated in about 71-80% cases. The adoption of a "watchful wait" involves an uncertain occupational and medical evolution since, although in some cases the stones will pass with no problems, in other instances they can result in severe, life threatening situations for the patient's health (intractable pain, anuria or sepsis). When a decision is made to treat the condition, there are two choices available: "in situ" SWEL (extracorporeal lithotrity), or URS (ureterorenoscopy), long-standing conflicting techniques each with its own advantages and disadvantages, which should now be considered complementary. SWEL's major disadvantage is the number of repetitions required and the long wait, sometimes even months, until the last fragment is passed. The greater strength of URS is that it can be resolutive in just one episode (95% cases), thus avoiding the obstruction problems that can arise after SWEL. In the Lithiasis-Lithotrity Unit of FJD, SWEL is the first therapeutical option for the treatment of stones in the distal ureter. SWEL and URS are equally likely to be performed although SWEL is the initial choice for efficiency reasons that are explained. We achieve 93.6% positive results with a 1.82% re-SWEL rate (retreatment), 0.60 coefficient of efficiency (EQ) and 0.69 modified coefficient of efficiency (EQM) (Chart). No serious complications were recorded. Morbidity is variable with little clinical significance. Distal ureter lithiasis can be treated with either URS and SWEL, both considered "different and complementary". The choice in each particular case and within each hospital will depend on availability of means to perform one or the other, equipment's efficiency, skill of the urologist, patient's preference and cost of each treatment.

    Availability and consumption of synthetic cannabinoids have risen recently in the USA and Europe. These drugs have adverse effects, including acute psychosis and bizarre behavior. In 2012, the United States Drug Enforcement Agency permanently banned five of the synthetic cannabinoids and in 2013, temporarily added XLR11, UR-144 and AKB48 to Schedule I of the Controlled Substances Act. As synthetic cannabinoid strains are added to the Schedule I list, new strains are being introduced into the market. XLR11 and UR-144 are two of the most recent additions to the synthetic cannabinoid drug class. To test collected oral fluid samples for XLR11 and UR-144, we developed a bioanalytical method that initially purifies the sample with solid-phase extraction and then quantitatively identifies the drugs with ultra-high-performance liquid chromatography-tandem mass spectrometry. The method was validated according to United States Food and Drug Administration guidelines and Scientific Working Group for Forensic Toxicology guidelines and the validation data showed that the method is an accurate, precise, robust and efficient method suited for high-throughput toxicological screening applications. We tested human subject samples with the developed method and found the presence of parent drugs (XLR11 and UR-144), their metabolites and their pyrolysis products in oral fluid. © The Author 2014.

    We present recent results from the UrQMD hybrid approach investigating the influence of a deconfinement phase transition on the dynamics of hot and dense nuclear matter. In the hydrodynamic stage an equation of state that incorporates a critical end-point (CEP) in line with lattice data is used. The equation of state describes chiral restoration as well as the deconfinement phase transition. We compare the results from this new equation of state to results obtained by applying a hadron resonance gas equation of state, focusing on bulk observables. Furthermore we will discuss future improvements of the hydrodynamic model. This includes the formulation of chiral fluid dynamics to be able to study the effects of a chiral critical point as well as considerable improvements in terms of computational time which would open up possibilities for observables that require high statistics.

    The field of high energy physics is very challenging in carrying out theories and experiments to unlock the secrets of heavy ion collisions and still not cracked and solved completely. There are many theoretical queries; some may be due to the inherent causes like the non-perturbative nature of QCD in the strong coupling limit, also due to the multi-particle production and evolution during the heavy ion collisions which increase the complexity of the phenomena. So for the purpose of understanding the phenomena, variety of theories and ideas are developed which are usually implied in the form of Monte-Carlo codes. The UrQMD model and the AMPT model are discussed here in detail. These methods are useful in modeling the nuclear collisions.

    Full Text Available AbstractHannah Arendt’s work is an important reference for Paul Ricœur. Her definition of power as the free action in concert of individuals within a community of equals, guaranteed by institutions, allows Ricœur to ground his reflection on the political dimension of recognition and justice. However, as I will show in this paper, such a definition is problematic, particularly because of the relation that Arendt establishes between power and authority, her decision to separate the social and the political, and her understanding of ideology, philosophy, and common sense in politics.After describing Arendt’s account of the relation between power and authority, I argue that, without rejecting the spirit of her political thought or her basic concepts, Ricœur’s reflections on the functions of ideology in his Lectures on Ideology and Utopia offer a broader but complementary vision that allows us to understand the issues that remain obscure in Arendt’s approach.Keywords: Arendt, Ideology, Authority, Power, Social.RésuméL’œuvre de Hannah Arendt constitue une référence importante pour Paul Ricœur. La définition arendtienne du pouvoir comme agir ensemble des individus au sein d’une communauté d’égaux garantie par des institutions, fournit en effet à Ricœur les bases de sa réflexion sur la dimension politique de la reconnaissance et de la justice. Cependant, cet article s’efforce de montrer qu’une telle définition est problématique, non seulement en raison de la relation qu’Arendt établit entre le pouvoir et l’autorité, mais aussi en ce qui concerne sa distinction du social et du politique, sa compréhension de l’idéologie, ainsi que sa conception de la philosophie et du sens commun dans le domaine politique.Après une analyse des thèses d’Arendt sur la relation entre le pouvoir et l’autorité, cet article soutient que, sans rejeter l’esprit de la pensée politique arendtienne et ses concepts de base, la

    Full Text Available Bean rust, caused by Uromyces appendiculatus, is a devastating disease of common bean (Phaseolus vulgaris in the Americas and Africa. The historically important Ur-3 gene confers resistance to many races of the highly variable bean rust pathogen that overcome other rust resistance genes. Existing molecular markers tagging Ur-3 for use in marker-assisted selection produce false results. Here, we describe the fine mapping of the Ur-3 locus for the development of highly accurate markers linked to Ur-3. An F2 population from the cross Pinto 114 (susceptible × Aurora (resistant with Ur-3 was evaluated for its reaction to four different races of U. appendiculatus. A bulked segregant analysis using the SNP chip BARCBEAN6K_3 placed the approximate location of Ur-3 in the lower arm of chromosome Pv11. Specific SSR and SNP markers and haplotype analysis of 18 sequenced bean varieties positioned Ur-3 in a 46.5 kb genomic region from 46.96 to 47.01 Mb on Pv11. We discovered in this region the SS68 KASP marker that was tightly linked to Ur-3. Validation of SS68 on a panel of 130 diverse common bean cultivars containing all known rust resistance genes revealed that SS68 was highly accurate and produced no false results. The SS68 marker will be of great value in pyramiding Ur-3 with other rust resistance genes. It will also significantly reduce time and labor associated with the current phenotypic detection of Ur-3. This is the first utilization of fine mapping to discover markers linked to rust resistance in common bean.

    This papers presents the concept of long-term underground retrievable storage (URS) of spent reactor fuel in unsaturated rock. Emplacement would be incremental and the system is planned to be experimental and flexible. The rationale for retrievability is examined, and a technical basis for 300-year retrievability is presented. Maximum isolation is the rationale for underground as opposed to surface storage. Although the potential repository site at Yucca Mountain Nevada would be suitable for a URS, alternate sites are discussed. The technical issues involved in licensing a URS for 300 years are simpler than licensing a 10,000 year repository. 16 refs

    This paper proposes to apply the Ultra-Relativistic Quantum Molecular Dynamics (UrQMD) approach to implement the PANDA project (GSI, Germany). Simulation of p bar A interactions has been performed at antiproton energies from 1 to 200 GeV by using the UrQMD model. We have studied average multiplicities, multiplicity distributions of various types of secondary particles, correlations between the multiplicities, rapidity, and transverse momentum distributions of the particles. The UrQMD model predictions on inelastic p bar A collisions have been found to reproduce qualitatively the experimental data. However, to reach the quantitative agreement, especially, in fragmentation regions, it is needed to modify the UrQMD model

Randomized controlled trial. Sindh Institute of Urology and Transplantation (SIUT), Karachi, from August 2010 to February 2011. One hundred and ninety patients with 10 - 15 mm proximal urteric stone, in each group were treated with ESWL and ureterorenoscopic manipulation by using an 8.0 or 8.5 Fr semi rigid ureteroscope. Intracorporeal lithotripsy was performed by using pneumatic lithoclast. The stone free rate were compared between groups by considering size of stone at one week after procedure. The success rate, retreatment rate, auxiliary procedure and complication rate were compared in each group. Success rate was 49.2% for ESWL and 57.8% for URS (p = 0.008). The re-treatment rate was significantly higher in ESWL group than in URS group (40% vs. 11 and 18% in URS group). Although ESWL is regarded as the preferred choice of treatment for proximal ureteric stone, the present results suggest that ureterorenoscopic manipulation with intracorporeal lithotripsy is a safe alternative, with an advantage of obtaining an earlier or immediate stone-free status. Laparoscopic approaches are reasonable alternatives in cases, where ESWL and URS have failed.

    Properties of equilibrated nucleon system are studied within the ultra-relativistic quantum molecular dynamics (UrQMD) transport model. The UrQMD calculations are done within a finite box with periodic boundary conditions. The system achieves thermal equilibrium due to nucleon-nucleon elastic scattering. For the UrQMD-equilibrium state, nucleon energy spectra, equation of state, particle number fluctuations, and shear viscosity η are calculated. The UrQMD results are compared with both, statistical mechanics and Chapman-Enskog kinetic theory, for a classical system of nucleons with hard-core repulsion.

    2016-01-01

    In recent years, synthetic cannabinoids have emerged in the illicit drug market, in particular via the Internet, leading to abuse of these drugs. There is currently limited knowledge about the specific enzymes involved in the metabolism of these drugs. In this study, we investigated the cytochrome...... of UR-144 and XLR-11, while inhibition of the other CYP enzymes in HLM had only minor effects. Thus, CYP3A4 is the major contributor to the CYP mediated metabolism of UR-144 and XLR-11 with minor contributions from CYP1A2. Users of UR-144 and XLR-11 are thus subject to the influence of potential drug-drug...... interactions, if they are concomitantly medicated with CYP3A4 inducers (e.g. some antiepileptics) or inhibitors (e.g. some antifungal drugs).

  18. UrQt: an efficient software for the Unsupervised Quality trimming of NGS data.

    Science.gov (United States)

    Modolo, Laurent; Lerat, Emmanuelle

    2015-04-29

    Quality control is a necessary step of any Next Generation Sequencing analysis. Although customary, this step still requires manual interventions to empirically choose tuning parameters according to various quality statistics. Moreover, current quality control procedures that provide a "good quality" data set, are not optimal and discard many informative nucleotides. To address these drawbacks, we present a new quality control method, implemented in UrQt software, for Unsupervised Quality trimming of Next Generation Sequencing reads. Our trimming procedure relies on a well-defined probabilistic framework to detect the best segmentation between two segments of unreliable nucleotides, framing a segment of informative nucleotides. Our software only requires one user-friendly parameter to define the minimal quality threshold (phred score) to consider a nucleotide to be informative, which is independent of both the experiment and the quality of the data. This procedure is implemented in C++ in an efficient and parallelized software with a low memory footprint. We tested the performances of UrQt compared to the best-known trimming programs, on seven RNA and DNA sequencing experiments and demonstrated its optimality in the resulting tradeoff between the number of trimmed nucleotides and the quality objective. By finding the best segmentation to delimit a segment of good quality nucleotides, UrQt greatly increases the number of reads and of nucleotides that can be retained for a given quality objective. UrQt source files, binary executables for different operating systems and documentation are freely available (under the GPLv3) at the following address: https://lbbe.univ-lyon1.fr/-UrQt-.html .

    According to current guideline recommendations extracorporeal shock wave lithotripsy (SWL) remains the first choice treatment for small and mid-sized renal calculi. However, the results of SWL treatment for lower pole stones can be disappointing whilst more invasive endoscopic modalities, such as flexible ureterorenoscopy (fURS) and percutaneous nephrolithotomy (PNL) are often considered more effective. This article summarizes a point-counterpoint discussion at the 9th eULIS symposium in Como, Italy, and discusses the potential advantages and disadvantages of the different therapeutic approaches.

    Alpha prime phase leads to decreased corrosion resistance and mechanical properties losses of duplex stainless steels. In this work mechanical and electrochemical tests were performed in duplex stainless steel UR 52N+ aged at 475 degree C for various periods in order to determine the sensibility of these tests to alpha prime presence. Hardness tests showed a gradual increase in its values; on the other hand, impact tests revealed that the material aged for 12h losses about 80% of energy absorption capacity of the solution annealed sample. Notwithstanding cyclic polarization tests showed that significant changes are only noted for aging times greater than 96h. (author)

    UR-13756 is a potent and selective p38 mitogen-activated protein kinase (MAPK) inhibitor, reported to have good bioavailability and pharmacokinetic properties and, thus, is of potential use in the treatment of accelerated aging in Werner syndrome. Irradiation of 2-chloroacrylonitrile and methylhydrazine in ethanol at 100 °C gives 1-methyl-3-aminopyrazole, which reacts with 4-fluorobenzaldehyde and a ketone, obtained by Claisen condensation of 4-picoline, in a Hantzsch-type 3-component hereocyclocondensation, to give the pyrazolopyridine UR-13756. UR-13756 shows p38 MAPK inhibitory activity in human telomerase reverse transcriptase-immortalized HCA2 dermal fibroblasts, with an IC(50) of 80 nm, as shown by ELISA, is 100% efficacious for up to 24 h at 1.0 μm and displays excellent kinase selectivity over the related stress-activated c-Jun kinases. In addition, UR-13756 is an effective p38 inhibitor at 1.0 μm in Werner syndrome cells, as shown by immunoblot. The convergent synthesis of UR-13756 is realized using microwave dielectric heating and provides a highly selective inhibitor that shows excellent selectivity for p38 MAPK over c-Jun N-terminal kinase.

    There are many IR permeable substances. When this is heated with IR beam, UR beam penetrated into the substance and heat up the substance from the inside. In this case, the inside gets hot quicker than the surface which gives much difference in the finish of the product. Characteristics of permeation and absorption of the IR beam vary by the type of the substance and the wave-length of the UR beam. Examples of effectiveness of far infra-red heater are: Baking of rice cake. Baking of PVC granules as a slip-stop for a working gloves. Far infra-red sauna (sweating effect around 50/sup 0/C). Tokyo Gas Co., Ltd. and other companies introduced an IR spectroscopic radiometer of Minarad Systems of USA to establish a data exchange system in 1984. The spectroscopic radio-meter system consists of 3 components, i.e., a spectrophotometric radiometer, a black body furnace, and a computer for data processing. (14 figs, 5 tabs)

    Full Text Available Les commentateurs s’accordent pour constater une évolution dans la pensée politique de Ricœur conduisant d’un radicalisme à un réformisme. Par-delà ces variations, on se propose plutôt de mettre en évidence la continuité d’un projet. Non seulement la critique du capitalisme se poursuit jusqu’au bout, mais la perspective du socialisme semble très tôt tenue pour improbable. Dans les deux cas, la préoccupation centrale porte sur la nécessité de raviver les traditions et de faire émerger l’élan initial sous la doctrine “ossifiée ” en les situant en tension critique entre elles pour qu’elles se corrigent mutuellement. Le projet politique de Ricœur consiste à établir en vis-à-vis libéralisme et socialisme.

    Svandra, Philippe

    2016-03-01

    In this article, the purpose is less praising Paul Ricoeur's work than enlightening how the reader may actually find some practical, even operative help in this philosophical thought. This is particularly true regarding the fields of medicine and care. Paul Ricœur is now worldwide renowned as a major philosophical figure of the 20th century, and with books such as "Oneself as another", he occupies a very peculiar place at the crossroads of phenomenology and hermeneutics. Through both these philosophical traditions, Paul Ricœur offers some narrative ethics which may greatly sustain caregivers in their reflexion. Yet, the aim of this article is to focus on this philosopher who invites us to inhabit and play a role in this world. The goal is also to bring out the pragmatic ethics that this thinker developed, based on Aristotelian and Kantian traditions. Then, this piece seeks to demonstrate how the three stages of Ricoeur's "petite éthique" (his "small ethics"), which are the self's aim "for the good life with and for others in just institutions" can shed some light on the ethical consideration of politicals and caregivers.

    Full Text Available Il est désormais connu que Michel Foucault s’est intéressé à la fin de sa vie à l’ ”herméneutique du sujet.” Mais cette histoire de la constitution du sujet (ou de la subjectivité fait étrangement l’économie d’une réflexion sur le rôle de la compréhension, alors que Foucault qualifie son travail d’ ”ontologie historique de nous-mêmes.” C'est sur ce point précis qu’est ici mis à l'épreuve le caractère médiateur de l’œuvre de Paul Ricœur, dont l’herméneutique du soi prend en charge une ontologie de la compréhension. Suite à ces considérations, la seconde partie de l’article cherche à démontrer que la théorie de l’agir de Ricœur peut favoriser le passage d’une reconnaissance de type objectale à une reconnaissance des capacités du sujet à se tenir pour responsable. Ce passage sera opéré directement sur le modèle d’analyse du “dernier Foucault,” c’est-à-dire son concept-clé de “processus de subjectivation.”In his later work, Michel Foucault manifested a strong interest for the “hermeneutics of the subject.” Yet this history of the constitution of the subject (or subjectivity does without any reflection on the role of understanding, even though Foucault characterizes his project as a historical ontology of ourselves. The power of mediation emphasized in the work of Paul Ricœur may help us redefine an ontology of understanding through a hermeneutics of the self. Following this, the second part of the article aims to show that Ricœur’s theory of action can facilitate a transition from the recognition of the self, first described as “objectivation,” to a recognition of the subject’s capacity to be held responsible. This passage will draw on the model of analysis in the later Foucault, specifically, on his key concept of the subjectivation process.

    Full Text Available Em pacientes com insuficiência renal, a encefalopatia é um problema comum que pode ser provocado pela uremia, deficiência de tiamina, diálise, rejeição de transplante, hipertensão, desequilíbrios hidroeletrolíticos e toxicidades medicamentosas. Em geral a encefalopatia se apresenta como um complexo de sintomas que progride de uma leve obnubilação sensitiva até delírio e coma. Esta revisão discute questões importantes com relação aos mecanismos de base da fisiopatologia da encefalopatia urêmica. A fisiopatologia da encefalopatia urêmica é até hoje incerta, mas postula-se o envolvimento de diversos fatores; trata-se de um processo complexo e provavelmente multifatorial. Distúrbios hormonais, estresse oxidativo, acúmulo de metabólitos, desequilíbrio entre os neurotransmissores excitatórios e inibitórios, e distúrbio do metabolismo intermediário foram identificados como fatores contribuintes. A despeito do progresso continuado na terapêutica, a maior parte das complicações neurológicas da uremia, como a encefalopatia urêmica, não respondem plenamente à diálise e muitas delas são desencadeadas ou agravadas pela diálise ou transplante renal. Por outro lado, estudos prévios demonstraram que a terapia antioxidante pode ser utilizada como terapia coadjuvante para o tratamento destas complicações neurológicas.In patients with renal failure, encephalopathy is a common problem that may be caused by uremia, thiamine deficiency, dialysis, transplant rejection, hypertension, fluid and electrolyte disturbances or drug toxicity.

En efecto, el teólogo suizo nunca sistematiza su comprensión de persona ­la distingue sí de los conceptos "individuo", "sujeto" y "espíritu­, pese a que se sirve de aquella como de uno de los pilares más significativos de su pensamiento. Los resultados obtenidos evidencian la complejidad de factores conceptuales, que demuestran que el yo tiene su fundamento último en el acto libre del amor infinito, que como tal constituye la persona desde el dinamismo intradivino de las relaciones opuestas entre Padre, Hijo y Espíritu SantoThis paper regards the concept of person as a concrete singularity in Hans Urs Von Balthasar's work. Such concept rose after a deep analytical reading of his voluminous work, in the light of the guiding question; Why am I, precisely I? The Swiss theologian distinguishes person from the concepts "individual", "subject" and "spirit", but he never synthesises his understanding of person, even though he uses it as one of the most significant pillars of his thought. The results obtained from the research confirm the complexity of the conceptual factors, which show that one's self has its deepest foundation in the free act of the infinite love, which as such, constitutes the person from the intra-divine dynamism of the opposed relations between the Father, Son and Holy Spirit

    Pb S-doped CdS nano materials were successfully synthesized using chemical bath. Transmittance measurements were used to estimate the optical band gap energy. Tailing in the band gap was observed and found to obey Ur bach rule. The diffraction X-ray show that the size of crystallites is in the ∼33 nm to 12 nm range. The peaks belonging to primary phase are identified at 2θ = 26.5 degrees Celsius and 2θ = 26.00 degrees Celsius corresponding to CdS and Pb S respectively. Thus, a shift in maximum intensity peak from 2θ = 26.4 to 28.2 degrees Celsius is clear indication of possible transformation of cubic to hexagonal phase. Also peaks at 2θ = 13.57, 15.9 degrees Celsius correspond to lead perchlorate thiourea. The effects on films thickness and substrate doping on the band gap energy and the width on tail were investigated. Increasing doping give rise to a shift in optical absorption edge ∼0.4 eV.

    2014-01-01

    Full Text Available The premise of Michel Tremblay’s revolutionary 1968 play, Les Belles-Sœurs , is a working bee. A group of working-class women gather to paste a million trading stamps, won in a sweepstakes, into booklets that once full can be redeemed for household goods. As the guests surreptitiously pilfer what they see as their hostess’s underserved windfall, their actions problematize the links between the individualistic aspects of consumer and material culture and the communal values they share as members of Quebec’s working class. Taking consumer culture and material desire as a starting point, this essay considers the relationship between the individual and the collective inherent in such matters and situates it in relation to the ways in which consumer culture, individual advancement, and national projects of collective betterment, namely the Quiet Revolution, are implicitly treated in the play. It is argued that Tremblay does not resolutely condemn consumer culture as something apart from the monumental social and political changes of the era, but rather sees in the practices of consumerism aspects of collective behavior that trouble interpretations of the accumulation of material goods as selfish or individualistic undertakings.

    The growing amount of unstructured text over Internet is tremendous. Text repositories come from Web 2.0, business intelligence and social networking applications. It is also believed that 80-90% of future growth data is available in the form of unstructured text databases that may potentially contain interesting patterns and trends. Text Mining is well known technique for discovering interesting patterns and trends which are non-trivial knowledge from massive unstructured text data. Text Mining covers multidisciplinary fields involving information retrieval (IR), text analysis, natural language processing (NLP), data mining, machine learning statistics and computational linguistics. This paper discusses the development of text analytics tool that is proficient in extracting, processing, analyzing the unstructured text data and visualizing cleaned text data into multiple forms such as Document Term Matrix (DTM), Frequency Graph, Network Analysis Graph, Word Cloud and Dendogram. This tool, VisualUrText, is developed to assist students and researchers for extracting interesting patterns and trends in document analyses.

  5. Supplement to LA-UR-17-21218: Application to SSVD

    We apply the formalism derived in LA-UR-17-21218 to the prescription for an RMI-based self-similar velocity distribution (SSVD) derived by Ham- merberg et al.. We compute analytically the true [mt(t)] and inferred [mi(t)] ejecta mass arriving at the piezoelectric sensor for several shots de- scribed in the literature and compare the results to the data. We nd that while the \\RMI + SSVD" prescription gives rise to decent estimates for the nal accumulated mass at the pin, the time-dependent accumulation rises too sharply and linearly to agree with data. We also compute the time-dependent pressure and voltage at the sensor, and compare the latter to data. The pres- sure does not rise smoothly from zero, instead exhibiting a strong surge as the leading edge of the ejecta cloud arrives, which produces an initial sharp spike in the voltage trace, which is not observed. These inconsistencies result from a discontinuity in the prescribed self-similar velocity distribution at maximum relative velocity.

    The Universe of RNA Structures DataBase (URSDB) stores information obtained from all RNA-containing PDB entries (2935 entries in October 2015). The content of the database is updated regularly. The database consists of 51 tables containing indexed data on various elements of the RNA structures. The database provides a web interface allowing user to select a subset of structures with desired features and to obtain various statistical data for a selected subset of structures or for all structures. In particular, one can easily obtain statistics on geometric parameters of base pairs, on structural motifs (stems, loops, etc.) or on different types of pseudoknots. The user can also view and get information on an individual structure or its selected parts, e.g. RNA-protein hydrogen bonds. URSDB employs a new original definition of loops in RNA structures. That definition fits both pseudoknot-free and pseudoknotted secondary structures and coincides with the classical definition in case of pseudoknot-free structures. To our knowledge, URSDB is the first database supporting searches based on topological classification of pseudoknots and on extended loop classification.Database URL: http://server3.lpm.org.ru/urs/. © The Author(s) 2016.

    This thesis begins a dialogue between Hans Urs von Balthasar’s theological aesthetics and Chinese academic aesthetics. We identify a tension between aesthetics and religion in Chinese academic aesthetics, and argue that a dialogue with von Balthasar’s work has the potential to contribute to the development of Chinese academic aesthetics with regard to overcoming that tension. In order to set a ground for the dialogue, von Balthasar’s theological aesthetics is examined in Par...

    Ozvenchuk, V.; Rybicki, A.

    2018-05-01

    The UrQMD transport model, version 3.4, is used to study the new experimental data on transverse momentum spectra of π±, K±, p and p bar produced in inelastic p + p interactions at SPS energies, recently published by the NA61/SHINE Collaboration. The comparison of model predictions to these new measurements is presented as a function of collision energy for central and forward particle rapidity intervals. In addition, the inverse slope parameters characterizing the transverse momentum distributions are extracted from the predicted spectra and compared to the corresponding values obtained from NA61/SHINE distributions, as a function of particle rapidity and collision energy. A complex pattern of deviations between the experimental data and the UrQMD model emerges. For charged pions, the fair agreement visible at top SPS energies deteriorates with the decreasing energy. For charged K mesons, UrQMD significantly underpredicts positive kaon production at lower beam momenta. It also underpredicts the central rapidity proton yield at top collision energy and overpredicts antiproton production at all considered energies. We conclude that the new experimental data analyzed in this paper still constitute a challenge for the present version of the model.

    The number of new psychoactive substances keeps on rising despite the controlling efforts by law enforcement. Although metabolism of the newly emerging drugs is continuously studied to keep up with the new additions, the exact structures of the metabolites are often not identified due to the insufficient sample quantities for techniques such as nuclear magnetic resonance (NMR) spectroscopy. The aim of the study was to characterise several metabolites of the synthetic cannabinoid (1-pentyl-1H-indol-3-yl) (2,2,3,3-tetramethylcyclopropyl) methanone (UR-144) by NMR spectroscopy after the incubation with the fungus Cunninghamella elegans. UR-144 was incubated with C. elegans for 72 h, and the resulting metabolites were chromatographically separated. Six fractions were collected and analysed by NMR spectroscopy. UR-144 was also incubated with human liver microsomes (HLM), and the liquid chromatography-high resolution mass spectrometry analysis was performed on the HLM metabolites with the characterised fungal metabolites as reference standards. Ten metabolites were characterised by NMR analysis including dihydroxy metabolites, carboxy and hydroxy metabolites, a hydroxy and ketone metabolite, and a carboxy and ketone metabolite. Of these metabolites, dihydroxy metabolite, carboxy and hydroxy metabolites, and a hydroxy and ketone metabolite were identified in HLM incubation. The results indicate that the fungus is capable of producing human-relevant metabolites including the exact isomers. The capacity of the fungus C. elegans to allow for NMR structural characterisation by enabling production of large amounts of metabolites makes it an ideal model to complement metabolism studies.

    The objective of the study was to systematically review the efficacy and safety of flexible ureterorenoscopy (F-URS) with holmium laser versus extracorporeal shock wave lithotripsy (ESWL) for the treatment of renal stone ESWL (WMD = 2.13, 95 % CI 1.13-4.00, P = 0.02). F-URS is associated with higher SFR, lower APR and RR than ESWL. F-URS is a safe and effective procedure. It can successfully treat patients with stones for 1-2 cm, especially for lower pole stone, without increasing complications, operative time and hospital stay. F-URS can be used as an alternative treatment to ESWL in selected cases with larger renal stones. However, further randomized trials are needed to confirm these findings.

    Epilepsy is a common clinical syndrome with recurrent neuronal discharges in cerebral cortex and hippocampus. Here we aim to determine the protective role of Uncaria rhynchophylla (UR), an herbal drug belong to Traditional Chinese Medicine (TCM), on epileptic rats. To address this issue, we tested the effect of UR on kainic acid (KA)-induced epileptic seizures and further investigate the underlying mechanisms. Oral UR successfully decreased neuronal death and discharges in hippocampal CA1 pyramidal neurons. The population spikes (PSs) were decreased from 4.1 ± 0.4 mV to 2.1 ± 0.3 mV in KA-induced epileptic seizures and UR-treated groups, respectively. Oral UR protected animals from neuronal death induced by KA treatment (from 34 ± 4.6 to 191.7 ± 48.6 neurons/field) through attenuating glial cell proliferation and S100B protein expression but not GABAA and TRPV1 receptors. The above results provide detail mechanisms underlying the neuroprotective action of UR on KA-induced epileptic seizure in hippocampal CA1 neurons. Crown Copyright © 2011.

    Ongoing changes in the synthetic cannabinoid drug market create the need for relevant targeted immunoassays for rapid screening of biological samples. We describe the validation and performance characteristics of an enzyme-linked immunosorbent assay designed to detect use of one of the most prevalent synthetic cannabinoids in urine, UR-144, by targeting its pentanoic acid metabolite. Fluorinated UR-144 (XLR-11) has been demonstrated to metabolize to this common product. The assay has significant cross-reactivity with UR-144-5-OH, UR-144-4-OH and XLR-11-4-OH metabolites, but assay's cutoff is 5 ng/mL relative to the pentanoic acid metabolite of UR-144, which is used as the calibrator. The method was validated with 90 positive and negative control urine samples for UR-144, XLR-11 and its metabolites tested versus liquid chromatography-tandem mass spectrometry. The accuracy, sensitivity and specificity were determined to be 100% for the assay at the specified cutoff. © The Author 2014. Published by Oxford University Press. All rights reserved.

A idade dos pacientes variou entre 18 e 58 anos, sendo 26 do sexo masculino e 9 do feminino. Todos os pacientes apresentavam níveis de uréia acima de 100 mg/dl e creatinina acima de 5,0 mg/dl. 10 pacientes foram mantidos com hemodiálise crônica, 13 com diálise peritoneal semanal e 10 com tratamento clinico conservador (controles. Foram realizadas medidas da condução nervosa motora nos nervos mediano, ulnar e peroneiro em todos os pacientes, concomitante com a avaliação clínica. Os pacientes foram divididos em grupos, conforme a intensidade da neuropatia presente. Os sintomas mais freqüentes foram diminuição do senso de vibração, câimbras e hipoestesia distai para tacto. O nervo mais afetado foi o peroneiro (97,82%, seguido do mediano e ulnar. O procedimento dialítico alterou pouco a condução nervosa, quando as aferições eram realizadas antes e depois da mesma diálise. Não houve nenhuma diferença estatisticamente significante entre os grupos de hemodiálise e diálise peritoneal na avaliação clinica ou eletroneurográfica. Em 7 pacientes seguidos por vários anos, a condução nervosa manteve-se estável em dois, aumentou em dois e baixou em três, acompanhando a evolução dos sintomas. Nos três que pioraram, houve desenvolvimento paralelo de hiper-paratireoidismo secundário. Os autores concluem que o nervo peroneiro é o que melhores condições fornece para o seguimento e avaliação clinica dos pacientes com uremia, apresentando tendência para diminuir a condução nervosa, quando existe piora da sintomatologia, sem relação com o tipo de diálise empregado.

    Wildfires represent an Anticipated Natural Phenomena Hazard for LANL and the surrounding area. The TWF facility is located in a cleared area and is surrounded on three sides by roadway pavement. Therefore, direct propagation of flames to the facility is not considered the most credible means of ignition. Rather, fires started by airborne transport of burning brands constitute the most significant wildland fire threat to the TWF. The purpose of this document is to update LA-UR-13-24529, Airborne Projection of Burning Embers – Planning and Controls for Los Alamos National Laboratory Facilities, to be specific to the TWF site and operations.

    The structure and potential of the information reference system OZhUR designed for the automated data processing systems of scientific space vehicles (SV) is considered. The system OZhUR ensures control of the extraction phase of processing with respect to a concrete SV and the exchange of data between phases.The practical application of the system OZhUR is exemplified in the construction of a data processing system for satellites of the Cosmos series. As a result of automating the operations of exchange and control, the volume of manual preparation of data is significantly reduced, and there is no longer any need for individual logs which fix the status of data processing. The system Ozhur is included in the automated data processing system Nauka which is realized in language PL-1 in a binary one-address system one-state (BOS OS) electronic computer.

    Full Text Available Les sociétés contemporaines connaissent un accroissement des inégalités, en termes de richesse et d’accès au pouvoir. Le fait gestionnaire, par son emprise croissante, joue un rôle particulièrement important dans l’actualisation des rapports de domination. Il se situe, en effet, à l'articulation entre les décisions politiques majeures et les transformations des sphères d'activité sociale. Mais c'est aussi par le renouvellement permanent de ses différentes composantes que le fait gestionnaire agit : procédant par expérimentations successives, il assure ainsi la perpétuation de rapports de domination, au cœur même des sphères économiques et professionnelles. Pour montrer la pertinence de cette approche, l’article élabore, dans le prolongement des acquis de la sociologie du travail, un modèle pour analyser la volonté gestionnaire de changer. En appliquant ce modèle à un vaste éventail de contextes professionnels, nous pointons et expliquons les effets de polarisation sociale qu’engendre cette volonté.The constant change at the heart relations oh dominationContemporary societies are experiencing growing inequalities in wealth and access to power. The process of “managerialism”, by its increasing influence, plays a particularly important role in updating the relations of domination. It is, indeed, located at the joint between the major policy decisions and changes in social spheres. But this process acts also by the constant renewal of its various components: proceeding by successive experiments, it ensures the perpetuation of relations of domination, at the heart of economic and professional spheres. To show the relevance of this approach, the paper develops, following the achievements of the sociology of work, a model to analyze the managerial will of change. Applying this model to a wide range of advanced professional contexts, we point out and explain the effects of social polarization generated by this will

    Although ureteroscopy (URS) has been established as a viable treatment for stones in obese patients, its safety and success has not been fully elucidated. The current study describes the worldwide prevalence of obesity in patients with urolithiasis and examines trends in URS outcomes, safety, and efficacy. This study utilized the Clinical Research Office of the Endourological Society (CROES) URS Global Study, which was a prospective, multicenter study including 11,885 patients treated with URS for urinary stones at 1 of 114 urology departments across 32 countries. The relationship between body mass index (BMI), diabetes, and creatinine, with retreatment, stone-free rates, complications, and long hospital stay, was examined with a multivariate logistic regression analyses. Of the 10,099 URS patients with BMI data, 17.4% were obese and 2.2% were super obese. Overall, 86.7% patients were stone free and 16.8% required retreatment. Higher BMI was associated with lower stone-free rates, and any deviation from normal weight was associated with higher retreatment rates. In multivariate analysis controlling for several variables including stone size, the association between BMI and lower stone-free rates with higher retreatment rates persisted. Intraoperative complications occurred in 518 (5.1%) patients, and 343 (3.4%) experienced a postoperative complication. Postoperative complications were more frequent in the underweight and super obese subjects, and there was no relationship between BMI and intraoperative complications. Although URS for stone disease was found to be an overall safe procedure for obese and super obese patients, efficacy of the procedure may be lower compared with normal-weight subjects and higher retreatment rates may be necessary.

As taxas de DGE da matéria seca (MS mostraram-se semelhantes para CAF e CAS. A adição de teores crescentes de uréia às forragens resultou em diminuição linear da DGE da MS tanto da CAF como da CAS. No caso da CAS, a DGE da fibra em detergente neutro diminuiu linearmente com concentrações crescentes de uréia. Os valores de pH do conteúdo ruminal foram maiores para CAS em relação a CAF, mas não ocorreram diferenças devidas à adição de uréia. Os teores do conteúdo ruminal em total de AGV e os de ácido propiônico foram maiores para a CAF em relação a CAS; os de ácido acético, ao contrário, foram maiores para a CAS.

On the other hand, the systematic dimension makes clear that Balthasar and Welte are trying to answer a question concerning the human response to the Revelation of God in Christ. Welte emphasizes the self-realization of faith, and Balthasar argues that the Revelation of God's love provides all the means necessary for human beings to understand this glorious love properly.

  7. Modelling the carbonation of cementitious matrixes by means of the unreacted-core model, UR-CORE

    International Nuclear Information System (INIS)

    Castellote, M.; Andrade, C.

    2008-01-01

    This paper presents a model for the carbonation of cementitious matrixes (UR-CORE). The model is based on the principles of the 'unreacted-core' systems, typical of chemical engineering processes, in which the reacted product remains in the solid as a layer of inert ash, adapted for the specific case of carbonation. Development of the model has been undertaken in three steps: 1) Establishment of the controlling step in the global carbonation rate, by using data of fractional conversion of different phases of the cementitious matrixes, obtained by the authors through neutron diffraction data experiments, and reported in [M. Castellote, C. Andrade, X. Turrillas, J. Campo, G. Cuello, Accelerated carbonation of cement pastes in situ monitored by neutron diffraction, Cem. Concr. Res. (2008), doi:10.1016/j.cemconres.2008.07.002]. 2) Then, the model has been adapted and applied to the cementitious materials using different concentrations of CO 2 , with the introduction of the needed assumptions and factors. 3) Finally, the model has been validated with laboratory data at different concentrations (taken from literature) and for long term natural exposure of concretes. As a result, the model seems to be reliable enough to be applied to cementitious materials, being able to extrapolate the results from accelerated tests in any conditions to predict the rate of carbonation in natural exposure, being restricted, at present stage, to conditions with a constant relative humidity

    2016-07-01

    Full Text Available In this article we present a theological-anthropological exploration, interpreting the figure of the angel as a mirror of our human condition. The point of departure is an analysis of Hans Urs von Balthasar’s approach to two major sources of our imagination of the angel: Bonaventure (1221−1274 and Maria Rainer Rilke (1875−1926. A comparison of his accounts of the Franciscan theologian and the Modern poet, respectively, reveals remarkable parallels in discourse, clustered around the tensions between vulnerability and openness, immanence and transcendence, and love and loss. Both Rilke and Bonaventure reject the classical angel figure as a human ideal, as it cannot integrate the paradoxes of human existence. Their alternative visions of what it means to be human, have many terms in common: heart, vulnerability, mortality, openness, abyss, suspension, transparency, receptivity, descent (kenosis, humility, poverty, etc. However, their meaning is different because Rilke does not recognize an absolute transcendence as the source of love and the vis-a-vis of the human. This immanentism leaves him no other option than the vain attempt to exorcize the angel figure altogether, while Bonaventure’s vision preserves the angel as an anthropological mirror, albeit an angel radically transfigured by God’s wounded love.

    Full Text Available Resumo A gencitabina é um fármaco utilizado no tratamento de vários tipos de neoplasias malignas. Há poucas descrições de associação entre a droga e a síndrome hemolítico-urêmica (SHU, apesar de os pacientes em questão terem ido a óbito em pelo menos 50% dos casos. O presente artigo relata o caso de uma paciente com 25 anos de idade em remissão diagnosticada com colangiocarcinoma que apresentou anemia hemolítica microangiopática acompanhada de insuficiência renal aguda anúrica após cinco ciclos de quimioterapia com gencitabina; as manifestações eram condizentes com SHU causada pelos efeitos colaterais do medicamento. A administração de gencitabina foi interrompida, e a paciente foi tratada com hemodiálise, transfusões de sangue, trocas de plasma, corticosteroides, doxiciclina e rituximabe. Foi atingido um desfecho favorável; mais especificamente, a hemólise foi controlada e a função renal foi plenamente restabelecida.

    Full Text Available Objetivos: Determinar la frecuencia de secuela renal después del evento agudo de Síndrome Urémico Hemolítico (SUH en niños y los factores asociados a la presencia de secuelas. Material y métodos: Estudio descriptivo y retrospectivo. Se revisaron las historias clínicas de los pacientes con SUH en el HNCH de 1997 al 2012, y se registraron datos de características clínicas, hallazgos de laboratorio y parámetros de función renal al ingreso, al alta y a los seis meses después del alta. En los casos que no contaban con control a los 6 meses, se intentó contactar a los pacientes para tomar nuevos controles. Resultados: Siete de 12 pacientes presentaron disminución en la tasa de filtración glomerular (TFG o proteinuria o hipertensión a los 6 meses o más después del episodio agudo, con un promedio de 30,75 meses de seguimiento. Tanto en los pacientes con secuelas como con recuperación renal se encontró una distribución similar de los factores asociados a secuelas como hipertensión al alta, proteinuria al alta, necesidad de diálisis, oligoanuria, leucocitosis > 20 000 cel/mm3 y síntomas neurológicos. Sin embargo algunas variables como oligoanuria y necesidad de diálisis se encontraron a niveles por debajo de los descritos en la literatura. Conclusiones: Es claro que existen pacientes con secuelas renales luego del episodio agudo de SUH que además presentan varios factores predictores de secuelas descritos en la literatura.

    The 'United Registries for Clinical Assessment and Research' [UR-CARE] database is an initiative of the European Crohn's and Colitis Organisation [ECCO] to facilitate daily patient care and research studies in inflammatory bowel disease [IBD]. Herein, we sought to validate the database by using fictional case histories of patients with IBD that were to be entered by observers of varying experience in IBD. Nineteen observers entered five patient case histories into the database. After 6 weeks, all observers entered the same case histories again. For each case history, 20 key variables were selected to calculate the accuracy for each observer. We assumed that the database was such that ≥ 90% of the entered data would be correct. The overall proportion of correctly entered data was calculated using a beta-binomial regression model to account for inter-observer variation and compared to the expected level of validity. Re-test reliability was assessed using McNemar's test. For all case histories, the overall proportion of correctly entered items and their confidence intervals included the target of 90% (Case 1: 92% [88-94%]; Case 2: 87% [83-91%]; Case 3: 93% [90-95%]; Case 4: 97% [94-99%]; Case 5: 91% [87-93%]). These numbers did not differ significantly from those found 6 weeks later [NcNemar's test p > 0.05]. The UR-CARE database appears to be feasible, valid and reliable as a tool and easy to use regardless of prior user experience and level of clinical IBD experience. UR-CARE has the potential to enhance future European collaborations regarding clinical research in IBD.

    To compare outcomes of ureteric and renal stone treatment with ureteroscopy (URS) in patients with or without the placement of a preoperative JJ stent. The Clinical Research Office of the Endourological Society (CROES) URS Global Study collected prospective data for 1 year on consecutive patients with ureteric or renal stones treated with URS at 114 centres around the world. Patients that had had preoperative JJ stent placement were compared with those that did not. Inverse-probability-weighted regression adjustment (IPWRA) was used to examine the effect of preoperative JJ stent placement on the stone-free rate (SFR), length of hospital stay (LOHS), operative duration, and complications (rate and severity). Of 8 189 patients with ureteric stones, there were 978 (11.9%) and 7 133 patients with and without a preoperative JJ stent, respectively. Of the 1 622 patients with renal stones, 590 (36.4%) had preoperative stenting and 1 002 did not. For renal stone treatment, preoperative stent placement increased the SFR and operative time, and there was a borderline significant decrease in intraoperative complications. For ureteric stone treatment, preoperative stent placement was associated with longer operative duration and decreased LOHS, but there was no difference in the SFR and complications. One major limitation of the study was that the reason for JJ stent placement was not identified preoperatively. The placement of a preoperative JJ stent increases SFRs and decreases complications in patients with renal stones but not in those with ureteric stones. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

    Hall, Alaric

    2009-06-01

    Full Text Available This paper seeks evidence among our extensive Scandinavian mythological texts for an area which they seldom discuss explicitly: the conceptualisation and handling of illness and healing. Its core evidence is two runic texts (the Canterbury Rune-Charm and the Sigtuna Amulet which conceptualise illness as a þurs (‘ogre, monster’. The article discusses the semantics of þurs, arguing that illness and supernatural beings could be conceptualised as identical in medieval Scandinavia. This provides a basis for arguing that myths in which gods and heroes fight monsters provided a paradigm for the struggle with illness. The article proceeds, more speculatively, to use the Eddaic poem Skírnismál and the Finnish Riiden synty as the basis for arguing that one cause of illness could be the transgression of moral norms.

    Este artículo tiene por objetivo encontrar pruebas en los numerosos textos mitológicos escandinavos sobre un tema sobre el que pocas veces estos tratan de forma explícita: la conceptualización y el tratamiento de las enfermedades y su curación. La principal prueba se encuentra en dos textos rúnicos (el Canterbury Rune-Charm (El conjuro rúnico de Canterbury y el Sigtuna Amulet (El amuleto de Sigtuna que conceptualizan la enfermedad como un þurs (‘ogro, monstruo’. El artículo trata sobre la semántica de þurs y sostiene que las enfermedades y los seres sobrenaturales podían conceptualizarse como idénticos en la Escandinavia de la época medieval, en base a lo cual afirma que los mitos en los que los dioses y los héroes luchan contra los monstruos representaban un paradigma de la lucha contra las enfermedades. De forma más especulativa, el artículo utiliza el poema eddaico Skírnismál y el poema finlandés Riiden synty como base para sostener que la transgresión de las normas morales podía considerarse una posible causa de las enfermedades.

O aminoácido encontrado no mosto em maior quantidade foi a prolina (327 mg/L seguido por treonina, arginina e alanina (239 mg/L. A maioria dos aminoácidos foi consumida pelas leveduras, logo após o início da fermentação. A liberação máxima de uréia no meio coincidiu com o máximo de consumo de arginina, que para a levedura Fermol Bouquet foi com 15ºBrix e para a levedura D47 com 11ºBrix. Confirmando a pouca preferência de prolina pelas leveduras, o teor deste aminoácido permaneceu elevado durante o processo fermentativo. Os aminoácidos, arginina, alanina, treonina, serina, ácido aspártico e isoleucina podem ser considerados as melhores fontes de nitrogênio para as leveduras.

El primer fenómeno en la patogénesis del síndrome hemolítico urémico es la lesión del endotelio vascular que de manera secundaria genera una cascada de fenómenos tales como la adhesión, agregación plaquetaria y el depósito de fibrina mediante distintos mediadores, cuyo resultado final sería la formación de trombos en la microcirculación: la microangiopatía trombótica.A review was made on the present aspects of the epidemiology and pathogeny of hemolytic uremic syndrome which is the result of a number of etiologic and pathogenic factors. Several Escherichia coli strains which produce a cytotoxin for Vero cells, called verotoxin or Shiga-like toxin(SL-T have been isolated. This toxin, particularly that produced by Escherichia coli serotype =157: H7 has been related to sporadic and epidemic cases and less frequently serotypes 0111, 026 and 0113 act through release of exotocins into blood stream. The first phenomenum in the pathogenesis of the hemolytic syndrome is vascular endothelium injure that as a side effect generates a series of phenomena such as adhesion, platelet aggregation and fibrin deposists through several mediators; the final result would be the formation of thrombi in microcirculation: the thrombotic microangiopathy.

With such behavior, there will be breakdowns of the protective oxide layers, and in the presence of chloride there will be immediate pitting. Polarization and electrochemical impedance spectrometry curves are presented and discussed. These curves make it possible to ascertain the corrosion domains and to compare the kinetics of different stainless steel alloys. These corrosion kinetics and the corrosion potentials provide a classification of the steels studied here: Inconel 690, zircaloy 4, 316 Ti steel, 17-4-PH, UR52N et URSB8.

    Full Text Available This paper explores the thought of Paul Ricœur from a feminist point of view. My goal is to show that it is necessary to narrate differently the history of our culture – in particular, the history of philosophy – in order for wommen to attain a self-representation that is equal to that of men. I seek to show that Ricoeur’s philosophy – especially his approach to the topics of memory and history, on the one hand, and the human capacity for initiative, on the other hand– can support the idea that it is possible and legitimate to tell our history otherwise by envisioning a more accurate truth about ourselves.

L’esthétique métaphorique, qui rappelle en de nombreux points l’esthétique mallarméenne, permet à l’auteur de réinterpréter et redécrire la réalité est-allemande en même temps que sa propre biographie. Par le recours au mythe et à l’intertextualité, ces dernières sont assimilées à la modernité esthétique, si bien que la RDA devient le territoire de la littérature moderne. Par la métaphore, Hilbig se réapproprie une réalité définie jusqu’alors par un pouvoir discrétionnaire.Ziel dieses Textes ist es, den Roman Eine Übertragung (1989 von Wolfgang Hilbig (1941-2007 mit Hilfe von Ricœurs La Métaphore vive sowie der Analyse der verschiedenen Titelbedeutungen (als Metapher, Übertragung oder Übersetzung zu verstehen. Diese Ästhetik der Metapher, die in mancher Hinsicht an die Mallarmésche erinnert, ermöglicht es dem Autor, zugleich die Realität der DDR und seine eigene Biographie neu zu interpretieren und zu beschreiben. Durch Rekurs auf Mythos und Intertextualität werden sie der ästhetischen Moderne gleichgesetzt, sodass die DDR zum Ort der Literatur der Moderne wird. Auf diese Weise gelingt es Hilbig, sich eine bis dahin von der politischen Macht dekretierte Wirklichkeit wieder anzueignen.

    Full Text Available  AbstractThe favourable reception of the analytic philosophy of language plays a central role in the composition of Ricœur’s literary hermeneutics. Following a brief description of the historical and methodological context of this reception, we show how Ricœur intends to link up phenomenology and analytic philosophy of language. Then we examine the role allocated to the analytic philosophy of language in establishing the idea of metaphor as a “more fundamental mode of reference” in The Rule of Metaphor. But once again Ricœur situates this semantic interpretation of metaphor within the context of an ontology. The result is methodological difficulties that mark the limits of Ricœur’s reception of the analytic philosophy of language.Keywords: Semantics, Metaphor, Ontology, Structuralism, Poetics.RésuméLa réception de la philosophie analytique du langage joue un rôle central dans la constitution de l’herméneutique littéraire de Ricœur. Après avoir tracé le cadre historique et systématique dans lequel s’inscrit cette réception, on montre comment Ricœur se propose d’articuler phénoménologie et philosophie analytique du langage. On étudie ensuite le rôle assigné à la philosophie analytique du langage pour la mise en place de la conception de la métaphore comme “mode plus fondamental de la référence” dans La métaphore vive. Mais Ricœur situe encore une fois cette interprétation sémantique de la métaphore dans un cadre ontologique. Il en résulte des difficultés systématiques qui marquent les limites de la réception de la philosophie analytique du langage par Ricœur.Mots-clés: Sémantique, Métaphore, Ontologie, Structuralisme, Poétique.

    The limiting factor for the use of Cisplatin in the treatment of different type of cancers is its toxicity and more specifically urogenital toxicity. Oxidative stress is a well-known phenomenon associated with Cisplatin toxicity. However, in Cisplatin treated group, abnormal animal behavior, decreased body weight, cellular and sub-cellular changes in the kidney and sperm abnormality were observed. Our investigation revealed that Cisplatin when administered in combination with a natural product derivative (Urs-12-ene-3α,24β-diol, labeled as IN0523) resulted in significant restoration of body weight and protection against the pathological alteration caused by Cisplatin to kidney and testis. Sperm count and motility were significantly restored near to normal. Cisplatin caused depletion of defense system i.e. glutathione peroxidase, catalase and superoxide dismutase, which were restored close to normal by treatment of IN0523. Reduction in excessive lipid peroxidation induced by Cisplatin was also found by treatment with IN0523. The result suggests that IN0523 is a potential candidate for ameliorating Cisplatin induced toxicity in the kidney and testes at a dose of 100 mg/kg p.o. via inhibiting the oxidative stress/redox status imbalance and may be improving the efflux mechanism. - Highlights: • Synthesis of a novel boswellic acid derivative (IN0523) • Counter oxidative stress induced due to Cisplatin • Protect against urogenital toxicity induced by Cisplatin

    Full Text Available Heritage tourism can increase incomes and stimulate the economy in former mining areas. Recreational tourism is one of the main sources of value of heritage. People from urban areas are willing to pay for access to these tourism options. The measurement of the economic impact of this availability is one of the main problems to confront, due to the immeasurable possibilities of heritage resources. The use of non-market values and their estimation by means of revealed preference methods should help to assess the economic value of this sort of resources from a recreational perspective. The travel cost method (TCM is widely used to value areas with recreational uses, such as lakes, beaches or forests, but there are not references to previous applications of this methodology in the field of mining heritage. In this work, TCM has been applied to obtain the economic value of El Soplao Cave (Geosite UR004, Cantabria, Spain as a recreational site, providing an estimated result of 34,961,162 euros.

    Full Text Available The Estero de Urías coastal lagoon is subjected to several anthropogenic activities and has been characterized since 1997 through the study of benthic fauna. We analyzed the spatial and temporal distribution of annelids and their relationships with environmental variables (depth, sediment temperature, grain size and organic matter in order to determine the current degree of perturbation. Density, species richness, diversity, dominance, biomass, and the application of classification and ordination techniques allowed us to distinguish 5 zones: 1 a non-perturbed zone at the mouth of the lagoon, 2 a slightly perturbed zone surrounded by mangroves and shrimp farms, 3 a temporarily perturbed zone close to the effluent of the thermoelectric plant, 4 a perturbed zone in front of the slaughterhouse and fish factory, and 5 a very perturbed zone subjected to sewage and industrial input. Only minor changes in granulometry and faunal composition were observed in comparison with previous data from the same area, suggesting that the lagoon is still perturbed due to the effect of anthropogenic activities.

    A frozen-stored blood clot of a wild brown bear cub Ursus arctos yesoensis that had been captured in Hokkaido, Japan was examined for piroplasma infection using polymerase chain reaction (PCR). Two 18S ribosomal RNA gene (SSU rDNA) sequences were generated. One 1565-bp sequence showed the highest similarity with B. gibsoni (95.9% identity) but, phylogenetically, was found to belong to a distinct lineage. The other sequence (1709-bp) could not be definitively assigned to a described taxon, sharing only limited homology to the closest named species (90.1% identity with C. felis). In order to enhance information obtained from the SSU rDNA sequence, further detection and sequence analysis of the CCTeta gene sequence were done revealing the simultaneous presence of three closely related genotypes (all in a monophyletic lineage) within a single bear host. This finding suggested the possibility that a new Babesia species (Babesia sp. UR1) might have been maintained in nature in wild brown bears. While the parasite's biology is yet unknown, to our knowledge, this is, excepting the single case documentation in 1910 of a hemoparasite in a bear at Russian zoo, the first reported case of piroplasms inhabiting a bear species.

    Full Text Available Si le recueil Cœur élégie rouge de James Sacré fait bien apparaître l’ombre d’une femme aimée et perdue, ne voir dans cette élégie qu’une dimension autobiographique serait réducteur, et il faut peut-être y entendre aussi, selon une approche réflexive, le poème qui échoue à restituer le monde, le végétal, les visages. De la sorte, l’élégie serait aussi le deuil de ce rêve, avec le constat de l’incompatibilité du poème et du monde, pour peu que le sujet lyrique s’abandonne à un aveu naïf de son amour. Le poème doit donc se reconstruire comme espérance, projet incessamment relancé d’une écriture par quoi la vie continue. L’élégie ne se contente plus de chanter la perte ni de méditer sur l’inadéquation de la langue, elle tire sa force d’un espoir qui renaît toujours et dont témoigne la prégnance de la métaphore végétale.

    Full Text Available This study undertakes a reading of Etienne de La Boétie’s Discours de la servitude volontaire, endeavoring to bring to light the way it convergences with and diverges from the political thought of Paul Ricœur, around the central concept of the will. On the basis of the twin notions of “denaturation” and of “pathology,” a course unfolds which aims at helping establish the people, in comparison with the institution of the State, through a political process revitalised by friendship. But the two thinkers differ when it comes to the resources of the will. This is reflected in the notion of freedom, conceived as absolute in La Boetie, while Ricœur emphasizes its contingency, which leads him to thematize it in terms of capabilities.

Se siguen tres simples pasos argumentativos: Primero se describe el método recurriendo a definiciones y explicaciones del mismo autor a nivel más bien teórico. Luego se lo ilustra con un ejemplo de interpretación concreto: el comentario exegético y hermenéutico del de la petición de glorificación que Jesús hace a su Padre (Jn 17,1-5 en el volumen dedicado al Nuevo Testamento de la afamada obra Gloria (IV Parte, volumen 7 del teólogo suizo. Finalmente se recogen los principales aportes del método a la exégesis y a teología bíblica. Entre estos últimos cobra especial resonancia para las ciencias bíblicas la atención que Balthasar presta a la participación de los intérpretes en el acontecimiento de salvación. En efecto, solo quien vive el Misterio Pascual puede en último término comprenderlo y explicarlo convincentemente. En concreto, el creyente al hacer exégesis del NT y, luego, al reflexionar su contenido teológico, puede darle sentido preciso, pues él vive y posee su núcleo o centro.This article proposes to shed light upon the biblical exegetical method used by Hans Urs von Balthasar in his studies of the New Testament.

An investigation was conducted in the municipality of Urânia, where the highest concentrations of chromium were detected regionally. It was defined that the originof this contamination is natural, since high concentrations of chromium were detected in aquifer sandstones (averageof 221 ppm and also in pyroxenes (6000 ppm, one of the main heavy minerals found in the sediments. Besides, noother possible diffuse or point sources of contamination were observed in the study area. Stratification of ground-waterquality was observed and the highest concentrations of Cr6+ were detected at the base of the aquifer (0.12 mg.L-1,where ground-water shows elevated values for redox potential (472.5 mV and pH (8.61. The origin of Cr6+ in water may be associated with the weathering of pyroxene (augite, followed by the oxidation of Cr3+ by manganese oxides. The highest concentrations of Cr6+ are probably related to desorption reactions, due to the anomalous alkaline pHfound in ground-water at the base of the aquifer.Concentrações anômalas de cromo hexavalente foram detectadas em águas subterrâneas do Aqüífero Adamantina em pelo menos 54 municipalidades localizadas na região noroeste do Estado de São Paulo, sudeste do Brasil, algumas vezes ultrapassando o limite máximo permitido para consumo humano (0,05 mg.L-1. Um estudo foi realizado no município de Urânia, onde as mais elevadas concentrações de cromo da região foram detectadas. A origem da contaminação foi definida como natural, pois foram detectadas concentrações de cromonos arenitos do aqüífero (média 221 ppm e em piroxênios (6000 ppm, um dos principais minerais pesados encontrados nos sedimentos

    Transuranic (TRU) waste leaving the Plutonium Facility at Los Alamos National Laboratory (LANL) is packaged using LANL's waste acceptance criteria for onsite storage. Before shipment to the Waste Isolation Pilot Plant (WIPP) in southeastern New Mexico, each payload container is subject to rigorous characterization to ensure compliance with WIPP waste acceptance criteria and Department of Transportation regulations. Techniques used for waste characterization include nondestructive examination by WIPP-certified real-time radiography (RTR) and nondestructive assay (NDA) of containers, as well as headspace gas sampling to ensure that hydrogen and other flammable gases remain at safe levels during transport. These techniques are performed under a rigorous quality assurance program to confirm that results are accurate and reproducible. If containers are deemed problematic, corrective action is implemented before they are shipped to WIPP. A defensive approach was used for many years to minimize the number of problematic drums. However, based on review of data associated with headspace gas sampling, NDA and RTR results, and enhanced coordination with the entities responsible for waste certification, many changes have been implemented to facilitate packaging of TRU waste drums with higher isotopic loading at the Plutonium Facility at an unprecedented rate while ensuring compliance with waste acceptance criteria. This paper summarizes the details of technical changes and related administrative coordination activities, such as information sharing among the certification entities, generators, waste packagers, and shippers. It discusses the results of all such cumulative changes that have been implemented at the Plutonium Facility and gives readers a preview of what LANL has accomplished to expeditiously certify and dispose of newly generated TRU waste.

En el año 1996 se publicó la secuencia histológica de su evolución en pacientes con períodos oligoanúricos prolongados. En los últimos años se han propuesto diferentes esquemas terapéuticos para enlentecer la evolución a la insuficiencia renal crónica terminal en distintas nefropatías, diabéticas y no diabéticas, cuya expresión puede comenzar aun en la adolescencia. En este trabajo se comenta la respuesta a dos esquemas terapéuticos de dos grupos de pacientes con SUH que presentaron proteinuria con o sin hipertensión arterial e insuficiencia renal. Se enfatiza la indicación de la dieta hiposódica y controlada en proteínas en el mismo momento del alta del paciente y la incorporación de un inhibidor de la enzima de conversión de angiotensina II, iECA, (enalapril al comienzo de la aparición de la proteinuria.Chronic renal failure (CRF is the most severe complication of hemolytic uremic syndrome (HUS. In 1996, the histological sequence of changes in patients with long lasting oligoanuric periods was clarified. In the last years different therapeutic schemes have been proposed in order to slacken the development of terminal CRF in different renal conditions secondary to diabetes and other diseases. Some of these cases can suffer the onset of renal failure at adolescence. In this review, response to two treatment schemes in different patients with HUS and proteinuria with or without hypertension or renal failure is commented. Early indication of poor sodium diet and strict control of protein intake at the very moment of hospital discharge is strongly recommended, as well as angiotensin II conversion inhibiting enzymes (iACE at the appearance of proteinuria.

Son parcours ne peut être dissocié de ses engagements politiques. Il combat les fondamentalistes islamistes et s'oppose au pouvoir en place. Il veut la reconnaissance du berbère, sa langue maternelle et celle de ses chansons, par l’État algérien. Il porte un regard sur l’histoire en reprenant des mythes tout en révélant des vérités. Il brise également des tabous de la société mais reprend des poncifs. Ses chansons, dans lesquelles se reconnaissent des milliers de personnes, disent les contradictions d'un individu tourmenté. L'imaginaire de ses poèmes est régional et rural. En revanche, son désir tend vers la nation entière et même vers l'universel. La tragédie de sa vie est indissociable des durs contextes politiques qu'expriment ses paroles. Algerian poet, singer and songwriter Lounès Matoub became an icon after his assassination. In the hearts of his people, he is the embodiment of an artist, having established himself with his talent, his outspokenness, his music and his poetry. His career cannot be dissociated from his political commitments. He fights against the Islamic fundamentalists and rebels against the governing power. He wants Berber, his mother language and that of his songs, recognized by the Algerian government. He examines history by recycling myths while revealing truths. He breaks societal taboos but unravels clichés. His songs tell of the trials of a tormented individual, but thousands of people recognize themselves in his songs. The scope of his poems is regional and rural. However, his desire extends to the whole nation, even to the universal.

En primer lugar se ha llevado a cabo la carbonatación acelerada (al 100% de C0(2 sobre probetas de pasta de cemento con distintas matrices cementantes tomando espectros de Difracción de Neutrones a lo largo del tiempo de experimento. La evolución de la intensidad de los picos correspondientes a cada una de las fases involucradas ha proporcionado datos de conversión fraccional en tiempo real, lo que ha posibilitado una aproximación cinética al fenómeno de la carbonatación y el desarrollo del modelo UR-CORE, basado en los principios de los sistemas de "núcleo sin reaccionar", típicos de los procesos en ingeniería química.One of the most important depassivation mechanisms of steel reinforcement in concrete is that caused by the neutralisation of the cement matrix.

On one hand, in-situ monitoring of the changes that take place in the phase composition of cement pastes during accelerated carbonation (100% C02 for different binders, is reported, by taking Neutrón Diffraction patterns in parallel with the carbonation experiments. The variation of the intensity of chosen reflections for each phase along the experiment supplied data, in real time, for fractional conversión of different phases. On the second hand, fitting of these results allowed to make a quantitative approach to the kinetics of the carbonation of the different phases, and develop the UR-CORE model that is based on the principies of the "unreacted-core" systems, typical of chemical

    The aim of the following article is to reconstruct Paul Ricoeur's concepts of human rights and human dignity by exploring some little-known texts, and to exemplify how these concepts are connected to a specific philosophical conception of human being, which is grounded in a Dialectics between transcendence and incarnation, freedom and dependence, identity and difference, capability and fallibility (fragility. In doing so, I will argue that Ricœur interprets human dignity, which he has never explicitly defined, through the prism of human capabilities, especially of the capability of being responsible. This interpretation allows him to take a differentiated position in the current bioethical debates on the rights of "potential persons" (Embrio and to illustrate how the Aristotelian phronèsis can be used in (bioethical cases where decisions are difficult to take.

    Full Text Available Il est admis que l’étude de la métaphore représente une inflexion décisive dans l’herméneutique de Ricœur. On sait peut-être moins que cette étude est concomitante de celle de la parabole, qui représente une inflexion également notable dans la contribution ricœurienne à l’herméneutique biblique. Il arrive pourtant qu’on tire argument de cette concomitance pour prétendre que le transfert de certains présupposés théologiques (quant à la nature du langage et de la Vérité s’en trouve facilité, et l’on ne craint pas d’avancer que les pages consacrées à l’analogia entis, dans La métaphore vive, prouvent la prégnance d’intérêts théologiques douteux dans l’élaboration de la théorie de la métaphore. Pour contrer cette critique dévastatrice, nous nous appuierons sur certaines analyses d’Umberto Eco, qui impliquent que la question des rapports entre analogia entis et métaphore n’a rien d’épistémologiquement scandaleux, et sur celles d’Alain qui, voici un siècle, a esquissé une interprétation des paraboles très proche de celle de Ricœur.

    Full Text Available O método de aplicação dos resíduos vegetais e dos fertilizantes nitrogenados pode afetar as reações do nitrogênio no solo, principalmente no plantio direto. O presente trabalho objetivou avaliar esses efeitos na disponibilidade de N para o milho em dois solos, em casa-de-vegetação. Combinações de métodos (ausência, incorporada ou na superfície de adição de palha de aveia (0,4kg m-2 e uréia (50mg N kg-1 foram aplicadas em unidades experimentais (7dm³ vaso-1 de dois solos, perfazendo um fatorial 3 x 3 x 2. O milho foi semeado no dia da aplicação dos tratamentos e as plantas foram cultivadas durante trinta dias, sobre um Neossolo e um Nitossolo, respectivamente com 50 e 520g kg-1 de argila e 8 e 48g kg-1 de matéria orgânica. A aplicação de palha de aveia, principalmente sobre a superfície do solo, beneficiou o desenvolvimento das plantas, possivelmente pela manutenção de maior quantidade de umidade nos solos. A aplicação de uréia não afetou nenhum parâmetro vegetal no solo argiloso, talvez porque a decomposição da matéria orgânica liberou mais N do que a imobilização ocasionada durante a decomposição da palha; no solo arenoso, entretanto, a uréia foi benéfica quando incorporada ao solo, e prejudicial quando adicionada na superfície, provavelmente devido à toxidez de amônia. Dessa forma, o efeito da decomposição da palha de aveia na disponibilidade de N foi função do teor de matéria orgânica original do solo.Management of both crop residues and nitrogen fertilizers affects soil N reactions especially on no-till systems. The magnitude of these effects on N availability to maize was evaluated in a greenhouse study. Combinations of oat straw and urea (absence, soil incorporated or surface applied were added to experimental units (7-dm³ per pot of two soils, in a 3 x 3 x 2 factorial combination.

    Full Text Available En 2007, Wilfried N’Sondé, Franco-congolais vivant à Berlin, publie en France son premier roman, Le Cœur des enfants léopards. Le livre rencontre un certain succès. Un an plus tard, la traduction allemande, Das Herz der Leopardenkinder semble faire une carrière comparable en Allemagne. On serait donc tenté de conclure qu’il n’y a pas tant de différence entre le lectorat français et le lectorat allemand. Un bon roman est un bon roman et il semble normal qu’il trouve son public des deux côtés du Rhin... Mais à y regarder de plus près, il apparaît que la réception du roman de Wilfried N’Sondé en France et en Allemagne suit des voies bien différentes. En France, les littératures postcoloniales sont essentiellement considérées à l’intérieur du cadre conceptuel de la francophonie et le roman de N’Sondé apparaît effectivement d’abord comme un roman francophone ; en Allemagne, il est plutôt rattaché à la littérature de la migration et est compris en fonction des traditions d’analyse qui s’y rattachent.2007 veröffentlicht der in Berlin lebende und aus Kongo stammende Franzose Wilfried N’Sondé, seinen ersten Roman, Le cœur des enfants léopards. Das Buch erfreut sich in Frankreich einer regen Aufmerksamkeit. Ein Jahr später scheint die deutsche Übersetzung, Das Herz der Leopardenkinder, am französischen Erfolg anzuknüpfen : ein guter Roman bleibt ein guter Roman und so scheint es nur normal dass, er auf beiden Seiten des Rheins sein Publikum findet. Dennoch wäre es falsch, daraus auf eine sehr ähnliche Leserschaft in den beiden Sprachräumen zu schließen. Bei genauerem Hinsehen zeigt sich, dass die Rezeption von Wilfried N’Sondés Roman in Frankreich und in Deutschland sehr unterschiedlich verläuft. Während der Roman in Frankreich im Kontext der postkolonialen Literatur in erster Linie als frankophones Werk rezipiert wird, konzentriert sich die deutsche Rezeption vornehmlich auf den

    Full Text Available Geralmente, grande parte do N de fertilizantes minerais e de plantas de cobertura de solo não é aproveitada pelo milho no cultivo imediato à aplicação, o qual pode ser absorvido pelas culturas cultivadas subseqüentemente. O objetivo deste trabalho foi avaliar o aproveitamento pelo milho do N residual da uréia, da crotalária (Crotalaria juncea e do milheto (Pennisetum americanum marcados com 15N, aplicados ao milho cultivado em sistema plantio direto, no ano agrícola anterior, num Latossolo Vermelho distroférrico no Cerrado. O estudo foi desenvolvido na fazenda experimental da Faculdade de Engenharia de Ilha Solteira-UNESP, Selvíria (MS, em áreas distintas. O delineamento experimental foi de blocos ao acaso com 15 tratamentos e quatro repetições, aplicados ao milho em 2001/02 e 2002/03. Os tratamentos foram dispostos em esquema fatorial 3 x 5, compreendendo a combinação de três coberturas de solo: crotalária juncea, milheto e vegetação espontânea (pousio, e cinco doses de N-uréia: 0, 30, 80, 130 e 180 kg ha-1. Após a colheita do milho, as duas áreas permaneceram em pousio nas entressafras e, em seguida, cultivadas novamente com milho, safras 2002/03 (experimento 1 e 2003/04 (experimento 2, utilizando adubação similar em todas as parcelas, para distinguir o efeito do N residual. O aproveitamento médio do N residual da parte aérea do milheto e da crotalária pelo milho foi inferior a 3,5 e 3 %, respectivamente, da quantidade inicial. A quantidade de N residual da uréia absorvida pelo milho aumentou de forma quadrática, no experimento 1, e linear, no experimento 2, em relação à dose de N aplicada, sendo o aproveitamento desta inferior a 3 %. As coberturas de solo não influenciaram o aproveitamento pelo milho do N residual da uréia, e vice-versa.The majority of N from mineral fertilizers and cover crops is usually not used by the very next corn crop, but can be absorbed by follow-up crops.

    Full Text Available A primeira adubação nitrogenada em cobertura para o arroz irrigado por alagamento pode ser realizada em solo seco ou em lâmina de água, afetando a taxa de volatilização de amônia e, conseqüentemente, a eficiência da adubação nitrogenada. O objetivo deste trabalho foi avaliar as perdas de N por volatilização de amônia com a aplicação de uréia em solo de várzea com diferentes níveis de umidade. O experimento foi conduzido em casa-de-vegetação, utilizando-se vasos contendo 5kg de um Planossolo Hidromórfico que recebeu os tratamentos: N0 - testemunha sem aplicação de uréia (solo úmido; USSE - aplicação de uréia em solo seco; USUM - aplicação de uréia em solo úmido; USSA - aplicação de uréia em solo saturado; e USLA - aplicação de uréia em solo com lâmina de água. As avaliações das perdas de amônia foram realizadas com coletores tipo semi-aberto estático após 10, 24, 34, 48, 72, 96, 144, 192 e 264 horas da aplicação de uréia. Ao final das 264 horas de avaliação, as perdas de amônia foram equivalentes para os tratamentos com aplicação em solo úmido, saturado ou sob lâmina de água, sendo os maiores picos de emissão de amônia entre 34 e 48 horas para o solo úmido e o saturado e 72 horas para a lâmina de água. A aplicação de N-uréia sobre a lâmina de água não evitou as perdas de N por volatilização de amônia.The first topdressing nitrogen (N application to flooded rice can be done on dry soil or soil after ponding water, affecting ammonia volatilization rate and, consequently, nitrogen fertilization efficiency. This study was aimed at quantifing N losses by ammonia volatilization after urea application in a wetland soil with different soil water status.

    Full Text Available The aim of the paper is to examine the process of decision-making among public administrators and answer the question of whether this differs from the way decisions is arrived at in the private sector. Interviews were conducted at three private companies and three public institutions. The results indicate that the administrators of public bodies and private enterprises appear to use similar methods in their decision-making process. The differences which were revealed relate to the size of the companies or institutions in question, rather than to form of ownership; i.e. the larger the operation, the more people are involved in the decision-making process. An analysis of the interviews reveals that the administrators of public bodies have a weaker mandate to make decisions than is the case in private enterprises, especially with regard to matters involving strategy. Otherwise there is little difference between small private businesses and small public institutions - their management often apply the rational approach and bounded rationality model to solve problems. The decision making process is very similar in larger private businesses and public institutions. Decisions take longer to make in public institutions where more momentous issues are involved, such as the construction of new buildings and strategy formation, in which case the process is characterised by staged decisions, often resulting in compromises between parties with contrasting interests. It should also be mentioned that many kinds of state legislation, e.g. relating to equal opportunities, information act and public employees, as well as strategies of district councils, often restrict the decision-making authority of public administrators. Such restraints do not apply to the same extent to private sector management. The consequences of the economic collapse exercised a considerably stronger impact on decision-making among public administrators than was the case with their

    Full Text Available RESUMO: Nesse estudo, o principal objetivo foi mensurar a concentração de tório, urânio e potássio aplicando a técnica da análise por Ativação Neutrônica Instrumental em dois compartimentos ambientais, águas superficiais e sedimento marginal, do rio Piracicaba, em Minas Gerais. Esse rio possui área de drenagem que inclui as regiões do Quadrilátero Ferrífero da Região do Vale do Aço, sujeitando-se a intensa ação antropogênica. As amostragens ocorreram em quatro pontos de coleta, localizados nos municípios de Fonseca, Rio Piracicaba, Nova Era e Ipatinga, nas estações seca e chuvosa. As concentrações determinadas para aqueles elementos no sedimento se apresentaram elevadas em comparação com os valores usualmente observados para o perfil geológico na região de estudo, denotando relação com o modelo de exploração econômica, notadamente com a mineração e siderurgia. Evidencia, também, a relação com a degradação do feldspato potássico e do quartzo. Na água superficial, constatou-se o incremento da concentração do tório e potássio em comparação com os valores do Conselho Nacional do Meio Ambiente (CONAMA, nº. 357/2005. Os achados desse estudo explicitaram a necessidade da adoção de medidas mitigadoras, visando a contenção dos danos ambientais.

    Full Text Available A volatilização de amônia (NH3 é a principal perda de nitrogênio (N responsável pela baixa eficiência da uréia aplicada na superfície do solo. Este trabalho objetivou avaliar os efeitos do modo de aplicação da uréia e da forma de manejo dos resíduos de aveia preta sobre a volatilização de amônia, em dois solos com diferentes teores de argila e matéria orgânica, sob condições de laboratório. Foram conduzidos dois experimentos num Nitossolo Vermelho (NV e num Neossolo Quartzarênico (NQ, contendo 520 e 50g kg-1 de argila, respectivamente. Os tratamentos consistiram de três formas de manejo do fertilizante nitrogenado (sem N, uréia aplicada na superfície e uréia incorporada ao solo e três métodos de manejo dos resíduos de aveia (sem palha, palha aplicada na superfície e palha incorporada ao solo. Utilizou-se o equivalente a 4,0mg ha-1 de palha e 255kg ha-1 de N. As unidades experimentais foram constituídas por colunas de PVC, contendo 1,47kg de solo argiloso e 2,1kg de solo arenoso. As colunas foram hermeticamente vedadas e a parte superior foi conectada, através de uma mangueira plástica, a frascos coletores com ácido sulfúrico. A quantidade de N-NH3 volatilizada foi determinada por arraste de vapor, em diferentes períodos, após a implantação do experimento. A aplicação superficial da uréia proporcionou maior volatilização de N-NH3 do que sua incorporação, nos dois solos. A manutenção da palha sobre a superfície do solo estimulou a perda de N-NH3 no solo arenoso, independentemente da forma de aplicação da uréia ao solo. A perda de N-NH3 foi numericamente maior e o período de máxima volatilização ocorreu antes no NQ, provavelmente devido ao menor teor de argila, à matéria orgânica e à menor capacidade de troca de cátions, relativamente ao NV.

    Full Text Available O N é o nutriente mais demandado pelas plantas. Contudo, para produção de mudas enraizadas de cacaueiro em substratos e sob irrigação freqüente não existem estudos de calibração de adubação nitrogenada. Os objetivos deste trabalho foram comparar a eficiência das adubações no substrato e foliar com uréia para mudas clonais de cacau e definir doses recomendáveis e nível crítico foliar de N. O experimento foi instalado em viveiro de produção de mudas do Instituto Biofábrica de Cacau, em Ilhéus, Bahia, em julho de 2006, envolvendo 10 tratamentos (duas formas de adubação, combinadas com cinco doses de uréia, em blocos casualizados, com quatro repetições. A parcela útil constituiu-se de 12 mudas clonais de cacaueiro cultivadas em tubetes, contendo 288 cm³ de substrato (50 % de fibra de coco e 50 % de Plantmax®. O substrato foi corrigido com 3,20 kg m-3 de calcário e adubado com 2,68 kg m-3 de superfosfato simples.

Distintas causas pueden desencadenar el proceso de MAT que caracteriza el SHU. En este documento consideramos SHU atípico (SHUa como el subtipo de SHU en el que los fenómenos de MAT son fundamentalmente consecuencia del daño producido en el endotelio de la microvasculatura renal y de otros órganos por desregulación de la actividad del sistema del complemento. En los últimos años se han identificado diversas mutaciones en genes del sistema del complemento asociados a SHUa, que explicarían aproximadamente el 60% de los casos de SHUa, y se han caracterizado funcionalmente numerosas mutaciones y polimorfismos asociados a SHUa que han permitido determinar que la patología se produce como consecuencia de la deficiente regulación de la activación del complemento sobre las superficies celulares y que lleva al daño endotelial mediado por la activación del C5 y de la vía terminal del complemento. Eculizumab es un anticuerpo monoclonal humanizado que inhibe la activación del C5, bloqueando la generación de la molécula proinflamatoria C5a y la formación del complejo de ataque de membrana. En estudios prospectivos en pacientes con SHUa su administración ha demostrado la interrupción rápida y sostenida del proceso de MAT, con una mejora significativa de la función renal a largo plazo y una reducción importante de la necesidad de diálisis y el cese de la terapia plasmática.

Se evaluó en forma prospectiva, entre 1999 y 2003, la respuesta a un tratamiento no convencional, en doce pacientes, edad 2.8 ± 0.6 años, que desarrollaron SUH con presencia de diarrea sanguinolenta (SUH D+ y evidencia serológica de toxina Shiga, los cuales en fase inicial presentaron parámetros hemodinámicos compatibles con shock séptico y compromiso neurológico grave. El protocolo incluyó transfusión de plasma fresco, pulsos de metilprednisolona (10mg/k/día por tres días consecutivos y plasmaféresis por cinco días, iniciados en las primeras 48 horas. Los doce pacientes ingresaron en terapia intensiva, presentando una puntuación de riesgo de mortalidad pediátrica (PRISM: 18 ± 2, con requerimiento de diálisis por 17.4 ± 4 días, asistencia ventilatoria mecánica por 10 ± 1días y soporte temprano con drogas inotrópicas por un período de 10.5 ± 1 días. La disfunción neurológica se presentó con convulsiones tónico-clónicas generalizadas por 5.4 ± 1 días en 8 pacientes y con convulsiones focalizadas en los restantes. Seis pacientes desarrollaron miocardiopatía dilatada y 8 presentaron colitis hemorrágica. Sobrevivieron a la etapa aguda de la enfermedad 9 pacientes. Al finalizar el primer año de seguimiento, dos de ellos presentaban secuelas neurológicas (escala de seguimiento de Glasgow; GOS 3 y 4 respectivamente y uno, fallo renal crónico. La introducción temprana de este protocolo podría beneficiar a pacientes con SUH D+ con inestabilidad hemodinámica grave y disfunción neurológica al inicio. Los mecanismos involucrados en esta temprana presentación clínica adversa de SUH D+ permanecen aún sin dilucidar.

    Full Text Available Avaliou-se o efeito de níveis crescentes de uréia na dieta de vacas em lactação sobre a produção e composição físico-química do leite. Foram utilizadas nove vacas holandesas em lactação, distribuídas em três quadrados latinos 3 x 3, com três tratamentos e três períodos de coleta. O experimento teve duração de 63 dias, divididos em três períodos de 21 dias. Os tratamentos consistiram de uma dieta controle, formulada para suprir 100% das exigências de PB, proteína degradável no rúmen (PDR e proteína não-degradável no rúmen (PNDR, composta de farelo de soja como principal fonte protéica e cana-de-açúcar como volumoso, e de duas outras dietas, semelhantes à dieta controle, mas com 0,75 ou 1,5% de uréia em substituição ao farelo de soja. As dietas foram isoenergéticas (1,53 Mcal/kg de energia líquida de lactação e isoprotéicas (16% de PB. Quando os resultados foram analisados por regressão polinomial simples, não houve efeitos das dietas sobre o consumo de MS, as produções de leite e de leite corrigida para 3,5% de gordura, os teores de proteína e gordura e a contagem de células somáticas do leite. Os níveis de substituição do farelo de soja por uréia não influenciaram o pH, a crioscopia ou a densidade do leite. No entanto, verificou-se efeito linear decrescente dos níveis de uréia na dieta sobre a acidez do leite. Os teores de proteína, gordura, lactose, uréia, extrato seco total e extrato seco desengordurado não foram afetados pelas dietas. Os resultados deste estudo sugerem que o uso de até 1,5% de uréia na MS da dieta de vacas em lactação não altera a produção, a composição e as características físico-químicas do leite.The objective of this trial was to evaluate the effects of three different dietary levels of urea on milk yield and composition. Nine lactating Holstein cows were randomly assigned to three replicated 3 x 3 Latin squares with three periods of 21 days each

Com essa finalidade foi desenvolvido um experimento em campo, em Nitossolo localizado na Fazenda Água Sumida próximo ao município de Barra Bonita (SP. O delineamento experimental foi o de blocos completos ao acaso, com quatro repetições. Os tratamentos estudados foram: sistema de plantio convencional (uma aração e duas gradagens e sistema de semeadura direta, ambos adubados com uréia (15N, na dose de 100 kg ha-1 de N em cobertura. Em todos os tratamentos, foi feita adubação de semeadura, aplicando-se 25 kg ha-1 de N na forma de uréia, 80 kg ha-1 de P2O5 na forma de superfosfato simples e 60 kg ha-1 de K2O como cloreto de potássio. No fim do ciclo foram realizadas comparações entre os tratamentos, da produtividade da cultura; da acumulação de nitrogênio pela parte aérea e parte subterrânea; da utilização do nitrogênio da uréia (15N pela cultura do milho e do nitrogênio residual do fertilizante no solo. As modificações no solo causadas pela implantação da semeadura direta não restringiram a disponibilidade de N para as plantas de milho e, por conseguinte, a produção de material seco. A eficiência de utilização do fertilizante nitrogenado (EUFN pelo milho e a recuperação do fertilizante nitrogenado no solo (RFNS foram, respectivamente, em torno de 45% e 30% para o N-uréia aplicado em cobertura não havendo diferença entre os sistemas de cultivo convencional e direto. Independentemente do sistema, o nitrogênio não recuperado da uréia, aplicado em cobertura na cultura do milho (NNR foi em média de 25%.This work aimed to study possible alterations in the production

    Full Text Available As microangiopatias trombóticas (MATs são condições caracterizadas por oclusão microvascular generalizada por trombos de plaquetas, trombocitopenia, e anemia hemolítica microangiopática. Duas manifestações fenotípicas típicas das MATs são a síndrome hemolítica urêmica (SHU e a púrpura trombocitopênica trombótica (PTT. Outras doenças ocasionalmente apresentam manifestações similares. Na dependência de prevalecer a lesão renal ou a cerebral, duas entidades patologicamente indistinguíveis, mas de alguma forma clinicamente diferentes, têm sido descritas: a SHU e a PTT. Injúria das células endoteliais é o fator desencadeante central na sequência de eventos que levam a MAT. Perda da trombo resistência fisiológica, adesão de leucócitos no endotélio lesado, consumo de complemento, liberação e fragmentação anormais do fator de von Willebrand (FvW, e aumento do estresse de cisalhamento vascular podem sustentar e ampliar o processo microangiopático. Anormalidades intrínsecas do sistema do complemento e do FvW podem acompanhar a predisposição genética à doença, que pode ter um papel chave, em particular nas formas recorrentes e familiares. Nos casos de SHU associada à diarreia (SHU+D, o dano endotelial renal é mediado (pelo menos em parte pela Shigatoxina (Stx bacteriana, uma família de toxinas elaboradas por certas cepas da Escherichia coli e Shigella dysenteriae. A evolução é geralmente boa na criança, na SHU associada a Stx, enquanto sequelas renais e neurológicas são mais frequentemente encontradas em adultos, formas familiares e atípicas da SHU e na PTT. Estudos recentes têm demonstrado que a deficiência na clivagem do FvW pela proteinase ADAMTS13 pode ser genética ou mais comumente adquirida, resultante da produção de anticorpos inibidores da ADAMTS13, causando a PTT. Durante a última década, demonstrou-se que a SHU atípica (SHU-D é uma doença de desregulação da via alternativa do

    Uncariae rhynchophylla (UR) is an herb which has blood pressure lowering and anti-inflammatory effects and has been prescribed traditionally to treat stroke and vascular dementia. In the present study, we examined whether UR suppress Atopic dermatitis (AD)-like skin lesions in NC/Nga mice treated with 2, 4-dinitrofluorobenzene (DNFB) under SPF conditions. The effect of UR in DNFB- treated NC/Nga mice was determined by measuring the skin symptom severity, levels of serum IgE, and of the amounts of IL-4 and IFN-gamma secreted by activated T cells in draining lymph nodes. Oral administration of UR to DNFB-treated NC/Nga mice was found to inhibit ear thickness increases and the skin lesions induced by DNFB. IFN-gamma production by CD4+ T cells from the lymph nodes of DNFB-treated NC/Nga mice was significantly inhibited by UR treatment, although levels of IL-4 and total IgE in serum were not. UR may suppress the development of AD-like dermatitis in DNFB-treated NC/Nga mice by reducing IFN-gamma production.

Foram utilizados 24 caprinos machos castrados, sem padrão racial definido, com peso vivo médio de 18 kg, distribuídos em blocos ao acaso, de acordo com o peso vivo. O período experimental foi de 20 dias: 15 para adaptação e 5 para coleta. A adição de teores crescentes de uréia ao resíduo desidratado de vitivinícola possibilitou aumento do consumo de matéria seca (MS, matéria orgânica (MO, proteína bruta (PB e fibra em detergente neutro (FDN, expressos em kg/dia, %PV e em g/kgPV0,75. Observou-se consumo linear crescente de nutrientes digest��veis totais (NDT, carboidratos totais (CT e carboidratos não-fibrosos (CNF, em %PV e g/kgPV0,75. Não houve diferença significativa nos consumos de NDT, CT e CNF expressos em kg/dia, cujos valores médios foram 0,363; 0,575 e 0,258, respectivamente. Entretanto, a adição de uréia ao resíduo não influenciou os coeficientes de digestibildade de MS, MO e FDN (médias de 48,13; 46,08 e de 20,37%, respectivamente. Os coeficientes de digestibilidade de CNF apresentaram crescimento linear, enquanto os de PB apresentaram comportamento quadrático, com valor máximo de 48,93%, com a adição de 1,3% de uréia ao resíduo. O uso de uréia no resíduo desidratado de vitivinícola elevou linearmente o consumo de nutrientes, contudo, o nível de 1,3% é o mais indicado, pois promove melhor digestibilidade da proteína bruta de dietas contendo esse alimento alternativo.The effect of the addition of 0.0, 0.5, 1.0 and 1.5% of urea to dehydrated vineyards residue, associated to forage cactus palm in the feeding of goats on intake and nutrient digestibility was evaluated.

Os efeitos de fertilização de nitrogênio atmosférico na relação simbiôntica e de fixação de nitrogênio Alnus rubra Bong. (amieiro vermelho e Frankia foram avaliados em um estudo de campo. Biosólidos classe B digeridos anaerobicamente e uréia sintética (46% N foram aplicados a taxas de 140, 280 e 560 kg ha-1 de N disponível em um solo tipo Areia Quartzosa. Ao contrário das plantas do grupo controle (17 µmol C2H4 g-1 hr-1 ou fertilizadas com biosólidos (26-45 µmol C2H4 g-1 hr-1, plantas fertilizadas com uréia não apresentavam fixação de nitrogênio após um ano de cultivo. Ao final do segundo ano, todas as árvores em todos os tratamentos fixavam N (7 µmol C2H4 g-1 hr-1; 4-16 µmol C2H4 g-1 hr-1; e 20-29 µmol C2H4 g-1 hr-1 para controle, uréia e biosólidos, respectivamente. Plantas cultivadas sob remediação com biosólidos apresentaram maior biomassa na parte aérea ao final do ano 2 (50 g; 51 g; e 190 g para controle, uréia, e biosólidos, respectivamente, e também maiores concentrações de nitrogênio foliar em ambos os períodos analisados (N foliar no ano 1 26 g kg-1, 27 g kg-1, e 40 g kg-1; N foliar no ano 2 17 g kg-1, 19 g kg-1, and 23 g kg-1, respectivamente para controle, uréia e biosólidos. A maior taxa de crescimento de A. rubra pode ter resultado em maior exigência em N e os biosólidos supriram quantidades adicionais de nutrientes capazes de sustentar o crescimento acelerado.

Para tanto, um experimento foi conduzido a campo, de março a agosto de 1995, na Embrapa Agrobiologia.O delineamento experimental adotado foi o de blocos ao acaso, com quatro repetições e seis tratamentos: adubação com esterco bovino (20 t/ha, aplicação de N-uréia (900 kg/ha, associação de esterco (20 t/ha com doses crescentes de N-uréia (225; 450 e 900 kg/ha e testemunha. O espaçamento foi de 0,6 m entre plantas, 0,6 m entre linhas e 0,8 m entre fileiras duplas, perfazendo um total de 24 parcelas com 9,6 m² cada. Verificou-se que as plantas adubadas exclusivamente com esterco apresentaram nos limbos foliares, menores conteúdos de nitrato que aquelas que receberam uréia complementar (17,6 mg/g M.F. e 303 a 579 mg/g M.F., respectivamente. Enquanto os teores de N-NO3- nos pecíolos de todos os tratamentos foram pelo menos três vezes maiores que os observados nos limbos foliares (1.830 e 561 mg/g M.F., respectivamente. AOMS recomenda uma dose diária aceitável (DDA de 53,3 mg de N-NO3-, para um adulto de 65 kg, isto é, a quantidade máxima deste composto que pode ser ingerida diariamente, através dos alimentos e da água. Considerando-se os dados obtidos no experimento, seria necessário o consumo de 2,67 kg de couve (limbos foliares quando produzida apenas com esterco (20 t/ha e 0,18 kg quando adubadas com esterco (20 t/ha + 111 kg/ha de uréia (próximo a dosagem recomendada pelo Manual de Adubação do Rio de Janeiro, para atingir a DDA

Marandu no período de transição águas-seca. A disponibilidade estimada de matéria seca das pastagens variou de 16.360 a 9.358 kg/ha. Para avaliação do desempenho produtivo, utilizaram-se 20 novilhos mestiços não-castrados, com 20 meses de idade e 376 kg de peso vivo. Os animais foram agrupados em lotes com pesos semelhantes, segundo um delineamento inteiramente casualizado, em quatro piquetes de 1,5 ha, onde receberam 1,5 kg/dia de suplemento isoprotéico (20% de PB, constituído de grãos de milho e soja moídos, mistura mineral e uréia nos níveis 0,0; 1,6; 3,2 ou 4,8% na matéria natural. O ganho médio diário - valor médio foi de 0,570 kg/dia - não foi influenciado pelos níveis de uréia do suplemento. Os parâmetros nutricionais foram avaliados utilizando-se quatro animais mestiços Holandês × Zebu, não-castrados, com peso médio inicial de 320 kg, fistulados no esôfago, rúmen e abomaso.

As temperaturas da solução foram iguais a 70 e 100 ºC para Eucalyptus grandis e Eucalyptus pellita, respectivamente. Para a produção dos adesivos e com o intuito de reduzir a sua viscosidade, os taninos foram sulfitados com sulfito de sódio e ácido acético. Formulações adesivas foram preparadas adicionando-se 0, 25, 50, 75 ou 100% de adesivos tânicos ao adesivo comercial de uréia-formaldeído. Foram fabricadas chapas de flocos de Pinus elliottii Engelm. e Eucalyptus grandis, utilizando-se 8% da formulação adesiva. As propriedades das chapas foram determinadas segundo a norma ASTM D-1037, de 1993. Observou-se que as propriedades das chapas foram superiores ao mínimo estabelecido pela norma ANSI/A 280.1-93, exceto no caso da resistência à umidade. Verificou-se, ainda, que o emprego de uma formulação adesiva contendo resina à base de uréia-formaldeído e tanino-formaldeído pode melhorar algumas propriedades.Bark tannins of Eucalyptus grandis and Eucalyptus pellita were extracted with 4,5% sodium sulfite in hot water solution for a period of three hours. Solution temperatures were 70 and 100ºC, for Eucalyptus grandis and Eucalyptus pellita bark respectively. Tannins were reacted with acetic acid and sodium sulfite to reduce adhesive viscosity. Adhesive formulations were prepared adding 0, 25, 50, 75 or 100% of tannin adhesives to the commercial urea-formaldehyde adhesive. Flakeboards were fabricated with 8% resin content. Board properties were determined according to ASTM D-1037 standards. Except for humidity, all board properties were superior to the values established by ANSI.A 208.1-93 commercial standard.

    Full Text Available Os processos fisiológicos das plantas são afetados pelo balanço de cátions e ânions absorvidos. O objetivo deste trabalho foi determinar a absorção de cátions e ânions quando plantas de capim-coastcross receberam doses elevadas de nitrogênio. O delineamento experimental foi o de blocos casualizados com quatro repetições, num esquema fatorial 2x5 - duas fontes de N: uréia e nitrato de amônio, e cinco doses de N: 0, 25, 50, 100, 200 kg ha-1 corte-1 . As doses de N foram aplicadas após cada corte num total de cinco cortes, durante a época das chuvas. A absorção de cátions e de ânions pelo capim-coastcross aumentou com o acréscimo das doses de N dos dois fertilizantes, sendo maior com o nitrato de amônio. Com doses crescentes de N, verificou-se entre os cátions maior absorção do K+, e do Cl- entre os ânions. Com exceção do N, a absorção do K+ foi superior à dos demais nutrientes, com redução no teor relativo de cálcio. Doses altas de N aplicadas em capim-coastcross, na forma de uréia ou de nitrato de amônio, favorecem a absorção de cátions e de ânions.Physiologic processes of plants are affected by uptake of cations and anions. The aim of this work was to determine the uptake of cations and anions when plants of coastcross grass received high doses of nitrogen. The experimental design was a randomized block, in a 2x5 factorial arrangement - two N sources: urea and ammonium nitrate and five N rates: 0, 25, 50, 100, and 200 kg ha-1 cutting-1 - with four replications. Treatments were applied after each of five consecutive cutting in the rainy season. Uptake of cations and anions by coastcross grass increased with increasing of N rates with both fertilizers, but was higher with ammonium nitrate. Increasing rates of N caused higher K+ uptake in relation to other cations, and in Cl- among the anions. Except for N, K+ uptake was greater than that of other nutrients, with a reduction on the relative content of Ca2

    Full Text Available Este trabalho teve como objetivo avaliar a qualidade de painéis compensados de Pinus taeda e de Pinus oocarpa, com 20 e 24 anos de idade, respectivamente, utilizando três diferentes formulações de adesivo uréia-formaldeído. Foram produzidos 18 painéis, com três repetições por tratamento. As formulações com maior proporção relativa de resina não influenciaram de forma conclusiva as propriedades físico-mecânicas dos painéis.Os painéis de P. oocarpa apresentaram valores médios de resistência da linha de cola, módulos de elasticidade e de ruptura superiores àqueles dos painéis de P. taeda. Os resultados das propriedades físico-mecânicas dos painéis indicaram grande potencial de utilização de lâminas de P. oocarpa para produção de compensados.The objective of this study was to evaluate the quality of both Pinus taeda and Pinus oocarpa plywood, 20 and 24-years-old, respectively, using three different formulations of urea formaldheyde resin. A total of 18 boards were produced, using three repetitions per treatment. The formulations containing a high relative proportion of the resin did not show a conclusive influence on the physical and mechanical properties of the boards. The boards made from P. oocarpa showed higher average values of the glue line strength, modulus of elasticity and modulus of rupture in comparison to boards of P. taeda. The results showed that the evaluation of the physical and mechanical properties of the board, indicate that the veneers of P. oocarpa have a high potentiality for plywood production.

    Full Text Available A quick revision of the available information on the life and works of Ibn Abī l-Rijāl (fl. Tunis ca. 996-1048 and an analysis of the contents of his Urjūza fī aḥkām al-nuŷūm which are compared to those of his better known Kitāb al- Barī‘ fī aḥkām al-nujūm. The conclusion is that both works are independent and that the Urjūza is not a summary of the Barī‘. The paper continues with biobibliographical data of the historian, mathematician and astrologer Ibn Qunfudh al-Qusanṭīnī (1339-1407, who is the author of a commentary of Ibn Abī l-Rijāl’s Urjūza dedicated to Abū Bakr b. Abī Mujāhid Gazī Ibn al-Kās, vizier of the Merinid sultans Abū Fāris (1366-1372 and Abū Zayyān (1372-1374. The work was probably written during the latter’s brief reign and before 1375, the date in which the dedicatee was exiled to Majorca. The work continues with an analysis of the contents of the commentary, the sources quoted, the astrological techniques used both by Ibn Qunfudh and by Ibn Abī l-Rijāl, and the use by the commentator of a set of astronomical tables derived from the zīj of Ibn Isḥāq. We find, finally, a detailed commentary of the horoscopes contained in Ibn Qunfudh’s work which includes one corresponding to the vernal equinox of the year 571 AD, in which there was a conjunction of Saturn and Jupiter which announced the arrival of Islam. There are eleven more horoscopes (two of them published previously which constitute an astrological history of Merinid Morocco between 1348 and 1366. Concerning the nine horoscopes analysed here, in six of them it has been possible to identify the subject or the event motivating the prediction, while three remain unidentified.

    Full Text Available Title: Teaching about sexuality and relation within science education analysed from the perspective of heteronormativityIn Sweden, a new subject syllabus for Science Studies (Naturkunskap in upper secondary school was introduced in 2011. In this syllabus knowledge about norms concerning sexualities and relations was brought to the fore as a core content. The aim of this paper is to explore how norms concerning sexuality guide the teaching, through a case study where three upper secondary school teachers were observed and their teaching was analysed from the perspective of companion meanings. All three observed teachers did teach about homosexuality, bisexuality, and transgender identities, often using genetics or evolution as their explanatory model. The teaching most often assumed that all students in the class were heterosexual, positioning LGBT-people as the Other, and did at no times take power perspectives into account.

    To support environmental management there is an increasing need for timely, accurate and detailed information on our land. Unmanned Aerial Systems (UAS) are increasingly used to monitor agricultural crop development, habitat quality or urban heat efficiency. An important reason is that UAS technology is maturing quickly while the flexible capabilities of UAS fill a gap between satellite based and ground based geo-sensing systems. In 2012, different groups within Wageningen University and Research Centre have established an Unmanned Airborne Remote Sensing Facility. The objective of this facility is threefold: a) To develop innovation in the field of remote sensing science by providing a platform for dedicated and high-quality experiments; b) To support high quality UAS services by providing calibration facilities and disseminating processing procedures to the UAS user community; and c) To promote and test the use of UAS in a broad range of application fields like habitat monitoring, precision agriculture and land degradation assessment. The facility is hosted by the Laboratory of Geo-Information Science and Remote Sensing (GRS) and the Department of Soil Physics and Land Management (SLM) of Wageningen University together with the team Earth Informatics (EI) of Alterra. The added value of the Unmanned Aerial Remote Sensing Facility is that compared to for example satellite based remote sensing more dedicated science experiments can be prepared. This includes for example higher frequent observations in time (e.g., diurnal observations), observations of an object under different observation angles for characterization of BRDF and flexibility in use of camera's and sensors types. In this way, laboratory type of set ups can be tested in a field situation and effects of up-scaling can be tested. In the last years we developed and implemented different camera systems (e.g. a hyperspectral pushbroom system, and multispectral frame cameras) which we operated in projects all around the world, while new camera systems are being planned such as LiDAR and a full frame hyperspectral camera. In the presentation we will give an overview of our activities, ranging from erosion studies, decision support for precision agriculture, determining leaf biochemistry and canopy structure in tropical forests to the mapping of coastal zones.

    Full Text Available Dans La Reine du silence, Marie Nimier se confronte à la figure de son père, l’écrivain Roger Nimier, mort lorsqu’elle avait cinq ans. Elle y montre le poids qui pèse sur l’enfant d’écrivain, mais aussi celui de l’héritage du secret familial et de l’injonction au silence. La difficulté de l’élaboration de son récit de filiation se révèle dans les constants recommencements et reformulations, qui constituent la marque de la tension angoissante entre l’obligation de dire et celle de taire. In La Reine du silence, Marie Nimier confronts her father’s memory – the writer Roger Nimier, who died when she was five years old. The novel describes the burden of being a writer’s child, along with that of inheriting family secrets and submitting to a code of silence. The difficulty of recounting her relationship with her late father is evidenced by the narrator’s numerous “false starts” and her constant rewritings. The hesitant nature of the narration captures an anguish born of two irreconcilable obligations : the need to put things into words and the pressure to remain silent.

    At present the investigation on alternative techniques to solve the problem with the growing amount of the wastes within European countries is a highly propitiated research area. The driving forces behind this priority are the current EU-legislations regarding the ban on landfill of combustible wastes and also the regulation on emission limits from waste treatment plants. The alternatives for waste treatment besides recycling are incineration, direct co-combustion and gasification. Co-combustion of waste with biomass can be considered a short-term solution for the problem but has the disadvantages of decreasing the capacity for clean fuels such as biomass and set demands on intensive modifications in the existing heat or heat and power plants. Waste gasification is an attractive alternative that can compete with incineration and co-combustion processes when the environmental and economical aspects are concerned. The product gas from a waste gasifier can be burned alone in conventional oil fired boilers or be co-fired with biomass in biomass plant. Fuel quality, gas cleaning system and questions related to ash treatment are the key parameters that must be considered in design and construction of a waste gasification process. Gasification of waste fractions that have limited contents of contaminants such as nitrogen, sulfur and chlorine will simplify the gas cleaning procedure and increase the competitiveness of the process. Heavy metals will be in captured in the fly ash if a gas filtering temperature below 200 deg C is applied. Activated carbon can be used as a sorbent for mercury, lime or alkali for capturing chlorine. For fuels with low Zn content a higher gas filtering temperature can be applied. Direct co-combustion or gasification/co-combustion of a fuel with low heating value affects two main parameters in the boiler: the adiabatic combustion temperature and the total capacity of the boiler. It is possible to co-fire: a) sorted MSW: 25%, b) sorted industrial waste: 30%, c) gas with LHV=3.3 MJ/m{sup 3} n: 20% and d) gas with LHV=5.7 MJ/m{sup 3} n: 35% with biomass without any critical effects on the boiler performance. In cases a) and b) problems with both corrosion and slagging and fouling is however expected. No such problems are encountered when co-firing with gasified waste is used. Studies on the economy for different systems for waste gasification show that the pay back time for the investment become: a) an existing 25 MW oil fired boiler with a gasifier producing a gas with LHV=5.7: 3 years, b) a 75 MW CHP with gasifier producing a gas with LHV=3.3 MJ/m{sup 3} n: 5-6years, and c) a 75 MW CHP with gasifier producing a gas with LHV=5.7 MJ/m3 n: 4-5 years. These pay back times must be considered in relation to the corresponding value for an incinerator of a similar capacity that is around 10 -15 years.

    The basic idea of this project is to study the possibilities to use source separated combustible material for energy conversion in conventional solid fuel boilers (i.e. not municipal waste incineration plants). The project has been carried out in three phases. During phase 1 and 2 a number of fuel analyses of different fractions were carried out. During phase 3 two combustion tests were carried out; (1) a boiler with grate equipped with cyclone, electrostatic precipitator and flue gas condenser, and (2) a bubbling fluidized bed boiler with electrostatic precipitator and flue gas condenser. During the tests source separated paper and plastic packagings were co-fired with biomass fuels. The mixing rate of packagings was approximately 15%. This study reports the results of phase 3 and the conclusions of the whole project. The technical terms of using packaging as fuel are good. The technique is available for shredding both paper and plastic packaging. The material can be co-fired with biomass. The economical terms of using source separated packaging for energy conversion can be very advantageous, but can also form obstacles. The result is to a high degree guided by such facts as how the fuel is collected, transported, reduced in size and handled at the combustion plant. The results of the combustion tests show that the environmental terms of using source separated packaging for energy conversion are good. The emissions of heavy metals into the atmosphere are very low. The emissions are well below the emission standards for waste incineration plants. 35 figs, 13 tabs, 8 appendices

    Full Text Available A produção de vegetais mais sadios e de boa qualidade e o fornecimento contínuo no mercado são fatores que têm determinado a adoção do sistema de cultivo protegido por um número maior de produtores. Porém, devido ao pouco conhecimento sobre o manejo do solo nessas condições, tem-se aplicado altas doses de fertilizantes, ocasionando problemas de salinidade e desequilíbrio nutricional. O objetivo desse trabalho foi avaliar os efeitos da aplicação da uréia e do cloreto de potássio nas características químicas de um LATOSSOLO VERMELHO Destrófico, principalmente nos índices de acidez e saturação em potássio. O N e o K foram aplicados em cobertura, nas doses equivalentes de 13,3 e 39,9 g m-2 de N e 5,5 e 16,6 g m-2 de K, em esquema fatorial (2x2+1, com tratamento adicional, sem a aplicação dos nutrientes. Cultivou-se pimentão, cultivar Mayata, em condições de ambiente protegido, durante 34 semanas. Após o pegamento das mudas, foi aplicado 1/6 dos nutrientes a cada dez dias. Ao final do ciclo, as formas de N nítrico e N amoniacal representaram melhor as doses do nutriente aplicados ao solo e não houve acidificação. As raízes tiveram significativo crescimento após a aplicação de N, enquanto que o aumento da dose de K, aplicado como KCl, prejudicou o crescimento radicular, provavelmente associado à alta concentração de K no solo e possíveis efeitos salinos, correspondendo a mais de 5,0 mmol c dm-3 e mais que 5,3% de saturação do K no complexo de troca, na camada superficial do solo.The production of healthy, high quality vegetables and the development of technologies for continuous supply to the market are important factors determining the adaption of protected cultivation systems by an increasing number of growers. Due to the little knowledge on soil management practices under these conditions, high fertilizer rates are normally applied, causing salinity problems and nutricional unbalances. The objective of

    Full Text Available Os impactos ambientais advindos da exploração e do beneficiamento de U são, em grande parte, idênticos àqueles causados por atividades minero-extrativistas em geral. Este trabalho teve o objetivo de determinar a partição geoquímica dos radionuclídeos naturais 238U, 226Ra e 210Pb em áreas circunvizinhas à Unidade de Mineração e Atividade de Urânio (URA das Indústrias Nucleares do Brasil S.A., localizada na Província Uranífera de Lagoa Real, no município de Caetité, na região sudoeste do Estado da Bahia. Foram coletadas amostras de solo em cinco áreas circunvizinhas à URA, representando as principais classes de solos da região, na profundidade de 0-20 cm. Nas cinco áreas, foram determinados o teor de atividade total e o fracionamento geoquímico nas frações: F1 - levemente ácida, F2 - reduzível, F3 - oxidável, F4 - alcalina e F5 - residual. As atividades totais médias foram, em Bq kg-1 de solo, de 50 para 238U, 51 para 226Ra e 159 para 210Pb. Os extraídos na fase potencialmente biodisponível (F1 foram: 11 % para 238U, 13 % para 226Ra e 3 % para 210Pb. O 238U apresentou maior biodisponibilidade nos solos mais ácidos e maior afinidade pelos óxidos de Fe, o que não ocorreu para o 226Ra, tendo este apresentado a maior biodisponibilidade. O 210Pb apresentouse predominantemente associado a F5. As percentagens elevadas de 238U, 226Ra e 210Pb na fração geoquímica F5 indicam que as atividades observadas nos cinco solos estão, predominantemente, associadas ao material que deu origem a esses solos, e não a um processo de contaminação artificial em função da atividade da URA.The environmental impacts resulting from uranium exploration and processing are to a great extent identical to those caused by extractive mining activities in general. This study aimed to determine the geochemical partitioning of the natural radionuclides 238U, 226Ra and 210Pb in areas surrounding the Uranium Mining and Concentration Plant (URA

    Full Text Available The aim of this research is to determine whether there are distinctions in runs among five and a half year old boys and girls. The research is based on studying 80 girls and 64 boys from seven kindergartens in Slovenia. The following five measurement methods have been used in our research: a 10-meter run, a 150-meter run, a 10-meter run with a flying start, 4-times 5-meter run, and a 300-meter run. The results of the t-test indicate a statistically characteristic difference among boys and girls in 300 m run test results only, that is, a method used for measuring aerobic endurance. Other motor skills results have shown that there are no statistically characteristic differences among boys and girls. It is important that sport activities for boys and girls are organized for both groups of children equally. Especially girls must take part in a variety of running exercises in order to increase their aerobic endurance. They should be encouraged to take part in a variety of games which require activating the energy component of movement. Based on the results of this research we can say that physical education (PE of preschool children should be planned regardless of sex and the PE program should be the same for both boys and girls. Cílem tohoto výzkumu je určit, zda existují odlišnosti v běhu chlapců a dívek ve věku 5,5 roku. Výzkum je založen na studii 80 dívek a 64 chlapců v sedmi mateřských školách ve Slovinsku.

Bakü’de bugün İçeri Şeher adıyla anılan eski Bakü yerleşiminde küçük ölçeklerde inşa edilmiş çok sayıda mescit bulunmaktadır. Bu makalede Selçuklular’ın Anadolu dışında Azerbaycan Bakü’de bıraktığı maddi kültür izlerinden en erken tarihli iki örnek ele alınmıştır. Çalışmada Türk dünyasında az bilinen bu iki eserin tarih, bani, plân, mimari ve bezeme gibi yönleriyle ayrıntılı biçimde ele alınması amaç edinilmiştir. Bu sebeple Bakü ve çevresindeki yapılarda: gerekli ölçümler, teknik çizimler ve fotoğraflama işlemleri yapılmıştır. Bunun ardından Bakü Berpa Arşivi’nde, Ahundov Kütüphanesi’nde ve Türkiye kütüphanelerinde kaynak araştırmaları ile çalışma tamamlanmıştır1. Türkler Anadolu’yu iskân edinmeleri ile başlattıkları süreçte elde ettikleri siyasi/askeri başarılarının yanında; belleklerinde getirdikleri estetik hissi, mimari anlayışı ve sanat biçimlerini de yeni yurtlarında uygulamışlardır. Bu hareketlilik boyunca geçtikleri güzergahlarda meydana getirdikleri kentlerde bıraktıkları izlerden, Anadolu öncesindeki kültürel mirasın örneklerini bulmak mümkündür.Her iki yapının da Selçuklular’dan günümüze ulaşabilmiş en erken tarihli iki eser olması Türk mimarisindeki gelişimin izlenmesi bakımından önemlidir. Selçuklular’ın Bakü’ye gelmesinden sonra inşa edilen ilk yapı olan Sınıg Gala Mescidi statik problemleri olan, sert kaba görüntülü ve yapıdan bağımsız büyük minaresiyle dikkat çekmektedir. Aşur Mescidi ise, çift katlı cephe düzenlemesi ve harimi bölen bezemeli destek kemeriyle az daha gelişmiş mimari arayışın bir ürünüdür.

A produção de Nmic obtida em amostras spot de urina foi comparada àquela obtida via coleta total. Dezesseis animais da raça Nelore mantidos em confinamento foram distribuídos em delineamento inteiramente casualizado em esquema de parcelas subdivididas, tendo nas parcelas os tratamentos em esquema fatorial 2 x 4 (dois níveis de concentrado, 25 ou 50%, e quatro categorias de bovinos, novilhas, machos castrados, machos não-castrados e vacas em lactação e nas subparcelas os seis dias de coleta. Não houve interação entre níveis de concentrado, categorias de animal e dias de coleta para as variáveis avaliadas. O volume urinário não foi influenciado pelos níveis de concentrado e os dias de coleta, contudo, foi significativamente maior para as vacas. A excreção de creatinina não foi afetada pelos tratamentos e dias de coletas, observando-se média de 27,1 mg/kg0,75.

    The aim of this study was to develop and validate an insurance claims-based algorithm for identifying urinary retention (UR) in epilepsy patients receiving antiepileptic drugs to facilitate safety monitoring. Data from the HealthCore Integrated Research Database(SM) in 2008-2011 (retrospective) and 2012-2013 (prospective) were used to identify epilepsy patients with UR. During the retrospective phase, three algorithms identified potential UR: (i) UR diagnosis code with a catheterization procedure code; (ii) UR diagnosis code alone; or (iii) diagnosis with UR-related symptoms. Medical records for 50 randomly selected patients satisfying ≥1 algorithm were reviewed by urologists to ascertain UR status. Positive predictive value (PPV) and 95% confidence intervals (CI) were calculated for the three component algorithms and the overall algorithm (defined as satisfying ≥1 component algorithms). Algorithms were refined using urologist review notes. In the prospective phase, the UR algorithm was refined using medical records for an additional 150 cases. In the retrospective phase, the PPV of the overall algorithm was 72.0% (95%CI: 57.5-83.8%). Algorithm 3 performed poorly and was dropped. Algorithm 1 was unchanged; urinary incontinence and cystitis were added as exclusionary diagnoses to Algorithm 2. The PPV for the modified overall algorithm was 89.2% (74.6-97.0%). In the prospective phase, the PPV for the modified overall algorithm was 76.0% (68.4-82.6%). Upon adding overactive bladder, nocturia and urinary frequency as exclusionary diagnoses, the PPV for the final overall algorithm was 81.9% (73.7-88.4%). The current UR algorithm yielded a PPV > 80% and could be used for more accurate identification of UR among epilepsy patients in a large claims database. Copyright © 2016 John Wiley & Sons, Ltd.

  2. Power Generation Utilizing Process Gases to Avoid Flaring; Elkraftproduktion ur processgas som idag facklas

    2011-01-15

    There is an increasing awareness that process gases, such as associated gases in oil extraction and byproduct gases in liquidizing of natural gas, can be utilized for energy production. Efficient energy production through the use of a gas turbine is profitable both from economical and environmental point of view compared to simply getting rid of the process gas in flares. Gases with an elevated amount of heavier hydrocarbons generally speaking burns faster and more intense compared to standard natural gas. In gas turbines with so called premixed, low emitting combustor systems this might induce changes in flame stability and the combustion stability connected with this. This might in turn affect the emissions from the gas turbine, the operation life and ability to operate. This work aimed at proving the potential of running Siemens standard SGT-600 and SGT-700 engines on gas with elevated amount of heavy hydrocarbons. Pentane (C{sub 5}H{sub 12}) was used as a model substance for heavy hydrocarbons and a facility for feeding and mixing pentane with natural gas was designed and built at Siemens delivery test bed in Finspaang. The two engines were demonstrated to be able to operate on the mixed fuel at various loads. The results show that both engines are able to stable operation on fuels with up to 10% by volume pentane content. Stable in the sense that no change in combustion dynamics was noted and the control system worked as normal. There were no impact on the temperature distribution through the turbine that could be seen and a boroscope inspection after the test did not reveal anything unusual. A slight increase in emissions of nitrogen oxides (NO{sub x}) was detected explained by a slightly more intense flame which also explains the simultaneous lowering of carbon monoxide (CO) emissions. Unexpected difficulties were faced by the external laboratories when the sampled gas samples should be analysed. If the difficulties in analysing the samples could have been foreseen, more effort would have been put into developing and evaluating the different methods before the test. The error margin in determining the pentane content was thus quite high, about 10% of the volumetric concentration. To conclude the work, it is demonstrated that SGT-600 and SGT-700 standard engines can operate on natural gas containing up to 10% by volume pentane with slight increase in NOx emissions. The limit of pentane in these tests was given by the gas feeding temperature and the dew point. At gas temperatures lower than the dew point, droplets of pentane form which can cause uncontrolled combustion resulting in burner hardware damages. Heating of the gas fuel allows for test on operation on gas with even higher contents of heavy hydrocarbons

    Full Text Available Negli ultimi decenni, ambientalisti, giornalisti, politici e parte dell?opinione pubblica si sono schierati contro l?uso dell?uranio impoverito nelle munizioni e nelle corazzature difensive, chiamando in causa gli effetti potenziali nocivi sulla salute. Ma quali informazioni e conoscenze hanno le persone comuni? Per ovviare ai limiti del paradigma psicometrico, che si è focalizzato prevalentemente sui processi cognitivi trascurando il contesto sociale nel quale la persona è inserita, il presente studio si è proposto di esplorare il contenuto e il campo delle rappresentazioni sociali del rischio ?uranio impoverito?. Si è fatto ricorso alla tecnica delle associazioni libere, chiedendo ai partecipanti (N= 1158, età media 26.7 anni, DS = 11.04, 42% uomini, con diverso orientamento politico di esprimere fino a 3 parole pensando a ?uranio impoverito? e di valutarne la positività/negatività su scala a cinque punti da 1 (molto positiva a 5 (molto negativa. Le analisi condotte sia mediante l?analisi del contenuto tematica che l?analisi delle corrispondenze lessicali hanno evidenziato l?organizzazione delle rappresentazioni intorno a differenti nuclei tematici, a carattere prevalentemente negativo: malattia/mortalità,, armi e guerra, catastrofe e esplosione atomica. Sono emerse inoltre differenze interessanti nelle rappresentazioni in base al genere, all?età e all?orientamento politico dei partecipanti: le persone più anziane sono più informate e consapevoli, associano termini carichi emotivamente, evocatori anche di un alone di colpevolezza intorno alla ?faccenda? dell?uranio impoverito. I giovanissimi invece, poco più che bambini quando il caso uranio impoverito è esploso all?attenzione delle cronache, sono meno esposti alle informazioni e fanno riferimenti a immagini quali bomba atomica e disastro nucleare. Coerentemente con l?effetto dell?uomo bianco, le donne tendono a riportare una maggiore percezione dei rischi associati all?uranio impoverito. L?orientamento politico di destra, rispetto a quello di sinistra, si associa all?utilizzo di termini più neutri e meno carichi emotivamente. In conclusione, i risultati hanno evidenziato che le rappresentazioni sociali dell?uranio impoverito sono organizzate in nuclei di significati riguardanti la morte, la malattia e l?atomica, nonostante non vi siano prove scientifiche che dimostrino la relazione tra l?esposizione all?uranio impoverito e il tumore nelle persone esposte, né che questo rischio riguardi la tecnologia nucleare.

    A construction of two-channel cryostat for analysing absorption spectra in solids at 300 and 77 K is described. Measurements are made by the differential method. A specimen to be studied is placed in one of the channels and a reference specimen of the same thickness in the other. A spectral dependence of the absorption coefficient of Si alloyed with S has been obtained. Changes in the absorption are due to phototransitions of electrons from various levels of sulphur to the conduction band as the temperature is lowered from 300 to 77 K

Au cours de la première moitié du XXe siècle, la référence à l’Orient est porteuse d’autres valeurs culturelles, sa présence se fait plus discrète et évolue vers une conception plus épurée et régionaliste, qui se veut intégrée au monde méditerranéen.Seaside and spa resorts had a serious weakness for orientalism. In France, this orientalism can be placed within a larger historical context of how Islamic architecture was perceived. It belongs to the rediscovery and redefinition of the Mediterranean myth during the 19th century. During the second half of this century, it was a style that blended well with eclectic tastes. During the first half of the 20th century, architectural references to the Orient came to bear other cultural values. The orientalism became more discreet and evolved towards a style that was more refined and regionalist, seeing itself as an integral part of the Mediterranean world.

    2012-09-15

    The consumption of fossil fuels must be reduced if we are to meet environmental and climate related goals and reduce the greenhouse effect. In contrast to fossil fuels, biogas is renewable and carbon dioxide neutral. Biogas is also the cleanest fuel on the market and has the potential to replace much of the fossil fuel used in Sweden. The residue produced after anaerobic digestion is a valuable fertilizer and soil conditioner. Organic wastes are recycled through the biogas process to become a resource. This creates a sustainable recycling of nutrients and energy between urban and rural areas, and between consumption and production. This handbook is intended as a source of information on biogas, targeting politicians and decision- and policy makers in local authorities, farmers and farmers' organisations, and indeed anyone with an interest in biogas in Sweden and abroad. The handbook starts with an introduction of biogas in Sweden today. In part two general information is given about biogas technologies, a description of the biogas process, from the use of substrates to the final distribution of biogas and organic residues, followed by short information about economic support and incentives. In the last part twelve Swedish biogas plants are described, which have been particularly successful, and which can therefore serve as models for the future. The plants are grouped into four different categories: codigestion plants, farm-based biogas plants, sewage treatment plants and industrial plants. Each case study is described as of March 2012. Production figures are given for 2011, unless otherwise stated.

  18. Fundamental paradox of survival determinism: the ur-etiology disease paradigm.

    Science.gov (United States)

    Krsmanovic, Pavle

    2013-06-01

    Following a common practice in medicine, biomedical researches tend to view various disease conditions as direct results of preceding, disease-causing events. Such events are commonly those that could have been previously detected and which have given the history of studies of particular diseases, been previously recognized as playing an important role in an onset and/or progression of the disease in question. Although such practice is justified from the very principles of experimental investigation and scientific observation, it comes short of finding the fundamental causes behind these disease conditions. This manuscript proposes a different view to the origin of some types of diseases as well as some other biological phenomena. Namely, the focus of the concept relates to a notion of survival determinism, proposed to have been in the very core of evolution of primordial organisms. Thereby, as various disease models are discussed in the light of the proposed mechanisms for adaptation, they could be seen as relicts of the early evolutionary history of life on Earth.

    Bjoerefors, Fredrik; Ulrich, Christian (Linkoepings Univ., Linkoeping (Sweden))

    2009-11-15

    The main objective with this project was to explore the possibility to employ electrochemical methods to reduce the metal content in waste products (slag and fly ash) from waste incineration facilities. The basic idea was to first dissolve the waste products in acid, and then to reduce and deposit as much as possible of the metal ions onto an electrode surface. Experiments were further performed to determine to which extent the deposited metals could be reoxidized into a separate and clean acidic solution (with metal recycling in mind). Parameters like the pH, deposition potential and time, and electrode area were investigated. The results clearly indicated that it to a large extent was possible to decrease the metal concentration in the slag and flyash, more than 90% of the copper ions could for example be extracted from the initial acidic slurry. However, a very strong acid was necessary to dissolve the waste products, and it was further necessary to increase the pH in this solution prior to the electrochemical reduction. In the report, some suggestions for future activities at a larger scale will also be addressed

    The aim of this project was to investigate the possibilities to produce ethanol from waste fractions. In this project, the investigation was limited to paper tubes and textiles. Project goals were to study: (a) Is it possible to produce ethanol from the selected waste fractions? (b) Which problems could arise in the hydrolysis and fermentation, and how could these be solved? (c) What yields could be achieved in practice, expressed as kg ethanol per kg waste? Tests have been made in both laboratory scale and in pilot scale. Weak acid hydrolysis was made in laboratory scale and in pilot scale, while enzymatic hydrolysis and SSF (simultaneous saccharification and fermentation), was made in laboratory scale only. Two different acids, phosphoric acid and sulphuric acid were used. The results from the experiments show that phosphoric acid have the best effect on dissolving the crystalline cellulosic structure of the two acids tested. This results in higher glucose yields before fermentation. The tests with paper tubes resulted in ethanol yields of 20-24 % based on dry raw material. Some textiles (jeans material) resulted in yields of 30-40% based on dry raw material. The results from the experiments show that yields of 25-30 l ethanol per 100 kg paper tubes, and 35-50 l ethanol per 100 kg textiles were reached. Waste fractions that were studied in this project are available in whole Sweden, but the relative share of the wastes depends on local conditions. In Boraas, the amount of paper tubes is approximately 300 tons per year, and textiles amounts to about 17 000 tons per year. About 25 % of the textiles are considered to be available for ethanol production. Any negative effects on the ethanol production from additives could not be noted in the experiments. For example, the additive poly-vinylic alcohol, PVA, which is present in the paper tubes, does not hamper the ethanol yield in any large proportion. During the experiments with textiles, comparative fermentation tests using pure cotton did not show any effect from dyes or other additives. In the experiments with the pilot reactor, optimum reaction time and temperature were 15 minutes and 180 deg C for weak acid hydrolysis of textiles. Corresponding optimum conditions for the experiments on paper tubes ware minutes and 200 deg C respectively.

  8. Second line of defense program overview LA-UR-00-5161

    Knepper, P.L.; Martin, D.D.W.

    2001-01-01

    Full text: The illicit trafficking of nuclear material is a major concern for non-proliferation and global stability. The nuclear Material Protection, Control and Accounting (MPC and A) program provides the first line of defense in protecting nuclear materials within Russia by upgrading safeguards and security measures at Russian nuclear facilities. Second Line of Defense (SLD) is a cooperative program between the Russian Federation State Customs Committee (RF SCC) and the United States Department of Energy (US DOE) to minimize illicit trafficking of restricted nuclear materials through Russian border control points. This partnership was solidified with the signing of a protocol between DOE and the RF SCC in June 1998. The relationship will soon be formalized in a Memorandum of Understanding that will outline the working relationships and commitments to successful implementation of the SLD Program. The Russians first acknowledged the threat of nuclear smuggling at a Nuclear Safety Summit in Moscow in April 1996. Nikolai Kravehenko, head of the Regional Information and Technical Customs Department of the RF SCC, subsequently stated in a July 1998 interview, 'In order to stop trafficking and illegal shipment to other countries we [also] have to tighten security at the facilities and equip our borders with reliable technology.' At the September 1998 U.S.-Russia Presidential Summit, the then Chairman of the RF SCC, Valery Draganov, highlighted the illicit trafficking challenge confronting Russia and requested U.S. assistance. Since 1991, a myriad of cases associated with the diversion and recovery of nuclear materials appear to be linked to the FSU. In the majority of cases, the material's origin was attributed to Russia. With more than 20,000 km of border contiguous to fourteen other countries, and more than 350 customs and border sites, addressing the threat posed by nuclear smuggling in Russia is not only an urgent but also an expansive problem requiring joint U.S.-Russian attention. The threat posed by the illicit trafficking of nuclear and nuclear-related materials and technologies must be addressed immediately by rapid upgrades of RF SCO's detection capabilities. The highest priority of the SLD Program continues to focus on equipping strategic RF SCC sites with radiation detection equipment according to an agreed-upon site prioritization analysis. However, it is also necessary to lay the groundwork for long-term viability of border enhancements through development and implementation of technical curricula for the RF SCO's training programs. The SLD Program has an established process for equipment deployment and site upgrades. The goal of this process is to assure sustainability of upgrades, optimize equipment investments, and promote program accountability. The SLD Program deploys Russian manufactured nuclear detection equipment. The Program works with the equipment manufacturer and RF SCC to ensure deployed equipment is sensitive to special nuclear material (SNM), test new equipment designs, and upgrade outdated equipment and technology wherever possible. The SLD team prioritizes site selection; therefore, equipment is deployed at collaboratively determined strategic locations. After the in-depth site prioritization study is completed, thorough site surveys ensure that the appropriate equipment, security enhancements, and upgrades are employed at each site to the maximum extent possible in order to increase detection capabilities. Vulnerability assessments ensure maximum effectiveness and are completed during the site surveys. The equipment and upgrade recommendations are based upon the results of the site vulnerability assessment and the site survey team reports. The equipment is manufactured and the site upgraded by private Russian corporations. After the site upgrades have been completed, the SLD team conducts a site acceptance test of the radiation detection equipment, as well as other site upgrades. The long-term sustainability of the SLD program requires employing Russian nuclear detection equipment. Since SLD's inception, DOE and its national laboratories have worked with private Russian firms to test and improve SNM-sensitive detection equipment. The Russian technology tested by the laboratories and the International Atomic Energy Agency (IAEA) has been found to meet the programmatic requirements. As additional border and customs sites are assessed for nuclear detection needs and new technical challenges are identified, the US/Russian SLD team will address these technical issues through focused collaborative efforts. Training is also a critical component of the SLD sustainability goal. Proper and safe use of nuclear detection instrumentation will be addressed through several phases of training. Upon equipment delivery, Russian specialists will conduct equipment operation, maintenance, and security procedures training. In addition to initial on-site training for customs inspectors, DOE and its affiliated labs will work with the RF SCC to create and implement training modules and courses tailored to the RF SCO's different tiers of personnel and their corresponding responsibilities in terms of identifying suspicious shipments or situations. The immediate successes of the SLD Program have been driven by the importance of the nonproliferation problem associated with the illicit trafficking of nuclear materials and catalyzed by the strong commitments of the Russian collaborators of the US national laboratories, and of the US DOE. The technology implemented under the program has resulted in immediate improvements in the ability of the RF SCC to detect and deter the illicit trafficking of nuclear material. This concrete impact will be augmented by the ongoing and future activities in the areas of training and technology deployment. We look forward to continued collaboration and successes. (author)

    Full Text Available Una lectura de la "Erkenntnis-kritische Vorrede" a Ursprung des deutsches Trauerspiels busca determinar en qué sentido Benjamin efectúa, en la teoría de las ideas allí esbozada, lo que él mismo llamó después una "tranposicion" del concepto goetheano de Urphänomen. El cotejo con algunos de los naturwissenschaftliche Schriften de Goethe sugiere que ambos autores aventuran una manera de pensar la relación entre los conceptos de verdad y totalidad a través de la confrontación y manipulación forzosa de las distinciones introducidas por la filosofía crítica de Kant. En este sentido sus esbozos lógicos y epistemológicos se dejan leer como marcadores de los momentos inaugural y concluyente del proyecto del idealismo alemán.

    Full Text Available Education has never only been about teaching facts about the world. It has also always been about passing on values to pupils. This aspect of teaching is not fulfilled if pupils only learn the meaning of the favoured values. A teacher should also be able to make his or her pupils believe in those values and to act according to them. Thus, teaching is also a kind of political socialisation. The values taught change historically and this change is related to the political history of a society. The empirical point of departure of this article is the fact that it is currently possible to observe signs of such a value transformation. We are not anymore to become good national patriots, atomistic possessors of negative rights or loyal cogs in the welfare state machinery, but democratic citizens in a radical sense. This article takes Jürgen Habermas’ Faktizität und Geltung as its theoretical point of departure. With the help of Habermas, the above mentioned value transformation will be interpreted. The aim of the article is to use Habermas’ theory to give a general idea of the possibility and meaning of a normative education of democratic citizens.

    Full Text Available This article compares Paul Ricoeur and Jacques Derrida on the theme of translation and in particular the ethical implications of the different ways in which they approach the untranslatable.  While Ricoeur’s account of translation as linguistic hospitality does offer a model for an ethical encounter with the other, I argue that this account does not go far enough. My central claim is that Ricoeur’s treatment of translation overemphasizes the movement of appropriation and integration.  While it may not be his intention, this emphasis could lead to a certain kind of complacency that would challenge the ethical claims Ricoeur makes in favour of translation as a paradigm.  I propose to supplement Ricoeur’s hospitality with Derrida’s untranslatable, in order to create a situation of constant discomfort thereby guarding against ethical complacency.

    2006-07-01

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) takes a look at the 800 kW wind turbine installed in 2001/2002 by the Ursern electricity utility near Andermatt, Switzerland, at a height of 2350 meters above sea level. The original prototype wind turbine contained various components from Swiss industry, such as the generator and the inverter. Because of difficulties (cracks in rotor blades, bankruptcy of the manufacturer, etc.) this installation was replaced by an Enercon 600-kW-wind turbine in 2004. Characteristic features of this turbine, such as is its adaptation for use under turbulent wind conditions at cold locations, are discussed. The results obtained in 2005 made it obvious that the utilisation of wind energy in alpine regions is possible and that the extreme conditions at this location do not significantly affect the efficient and safe operation of such an installation. Together with the presence of a meteorological station in the vicinity, optimal operating conditions prevail at this site for further research projects in connection with icing-up of turbine blades and wind energy. The report describes the installation and de-installation of the first turbine and the installation of the present one. Initial experience gained with the installation and its certification by the 'Naturemade' eco-power programme is discussed, as is future expansion at the site.

    Uncaria rhynchophylla (Miq.) Jack (UR) and Gastrodia elata BI. (GE) are traditional Chinese herbs that are usually used in combination to treat convulsive disorders, such as epilepsy, in China. The aim of this study was to compare the anticonvulsive and free radical scavenging activities of UR alone and UR in combination with GE in rats. For the in vitro studies, brain tissues from 6 male Sprague-Dawley (SD) rats were treated with 120 microg/ml kainic acid (KA), with or without varied concentrations of UR or UR plus GE. For the in vivo studies, male SD rats (6 per group) received intraperitoneal (i.p.) injection of KA 12 mg/kg to induce epileptic seizures and generation of free radicals, with or without oral administration of UR 1 g/kg alone or UR 1 g/kg plus GE 1 g/kg. Epileptic seizures were verified by behavioral observations, and electroencephalography (EEG) and electromyography (EMG) recordings. These results showed that UR alone decreased KA-induced lipid peroxide levels in vitro, whereas UR plus GE did not produce a greater effect than UR alone. UR significantly reduced counts of wet dog shakes (WDS), paw tremor (PT) and facial myoclonia (FM) in KA-treated rats and significantly delayed the onset time of WDS, from 27 min in the control group to 40 min in the UR group. UR plus GE did not inhibit seizures more effectively than UR alone, but did further prolong the onset time of WDS to 63 min (P < 0.05 vs. UR alone). UR alone reduced the levels of free radicals in vivo, as measured by lipid peroxidation in the brain and luminol-chemiluminescence (CL) counts and lucigenin-CL counts in the peripheral whole blood, but the combination of GE and UR did not reduce free radical levels more markedly than UR alone. In conclusion, our results indicate that UR has anticonvulsive and free radical scavenging activities, and UR combined with GE exhibit greater inhibition on the onset time of WDS than UR alone. These findings suggest that the anticonvulsive effects of UR and

  7. No Space. Nowhere. Refugees and the Problem of Human Rights in Arendt and Ricœur.

    Directory of Open Access Journals (Sweden)

    Hille Haker

    2018-02-01

    Full Text Available In the wake of the recent global refugee and migration crisis, Hannah Arendt’s defense of the right to have political rights has become prominent again. Her work is read as an early reminder that the internationally promoted human rights regime may be merely a rhetorical reference, without the will or international authority for political action. I examine Arendt’s analysis in its historical context and then turn to consider Ricœur’s understanding of human rights. The capability to respond to and to be held accountable by others marks Ricœur’s ethics of responsibility. He agrees with Arendt that legal authority must rest upon power (Macht and not domination (Herrschaft, but he insists that the undercurrent of common power is the moral capability of an agent. The essay examines the ramifications of Ricœur’s ethics for the current crisis of refugees and migration, and it argues that he offers, at the same time, a correction useful for the ethical foundation of human rights.

    Directory of Open Access Journals (Sweden)

    Claude Laroche

    2012-04-01

    Full Text Available La station balnéaire d’Hossegor (Landes a connu son véritable lancement à partir de 1923, alors que le site avait été révélé quelques années auparavant, au tout début du siècle, par les séjours d’un groupe d’écrivains, parmi lesquels J.-H. Rosny jeune (1859-1948, Maxime Leroy (1873-1957 et Paul Margueritte (1860-1918. A partir de cet exemple landais, l’exposé tend à démontrer combien la création d’une station balnéaire, de sa découverte à sa promotion en passant par sa révélation au monde extérieur, doit au jeu des réseaux de tous ordres. Contemplatifs, les premiers occupants d’Hossegor n’auront pourtant de cesse de faire connaître le lieu en s’appuyant pour cela sur un puissant réseau de relations, notamment journalistiques. Actif, le promoteur de la station, Alfred Eluère (1893-1985, ne pourra assurer son succès qu’en utilisant le cercle relationnel très ouvert et très efficace que ses multiples activités – immobilières, mais aussi sportives et politiques – l’auront amené à constituer. Sa venue à Hossegor n’est d’ailleurs rien d’autre que le résultat de circonstances permises par le jeu de tout un tissu de relations au milieu duquel on trouve entre autres Maurice Martin (1861-1941, personnage haut en couleur, journaliste cultivant lui aussi au plus haut point le réseau des connaissances. Une fois la station lancée, la promotion immobilière saura jouer de tous les ressorts offerts par ces différents réseaux pour amener sur place la clientèle : de la propagande journalistique au réseau des agences immobilières en passant par le propre réseau relationnel d’Eluère. Parallèlement, le réseau des architectes sera lui aussi particulièrement actif, que ce soit pour s’attirer la commande ou pour propager la formule régionaliste. En conclusion, à côté de l’histoire officielle des stations balnéaires – une histoire au premier degré que les archives documentent relativement facilement – on ne peut passer à côté d’une autre histoire, plus souterraine mais qui a largement autant d’influence : celle des réseaux.

    Full Text Available The idea of the Christian universalism is a key-subject of Balthasar’s theology. The proprium of this autor appears more clearly analysing the distance in the subject of analogia entis and the natural theology which Barth maintains. A basic element of Bathasar’s reflection about the Christian universalism has its roots in the origin of the assertion that the creation in Christ is united with the contemplation of the cosmic Christ and with the will to emphasize the universal character of the salvation happened in Christ (the concretum universale. Thus the approach is a profound comprehension of the salvation “in Christ”. The Chalcedonic formula enlarged since the fourth Lateran Council becomes a “law” for the interpretation of the (metaphysical reality. Balthasar propounds in this way an ontology in those center the personal reality is situated. At the end the reader finds a prospective critique to Balthasar’s position

    The forest will, most probably, play an important part in the sustainable society of the future, as a producer of timber and pulp, in the conversion of bioenergy and in the chemical industry. The forest also is of great importance for recreation. The question is how we can make the forest last for all these things, without lessening its values of nature and production. Some are speaking of an enhanced fertilization of parts of the forest to maintain productivity. The fertilizer could consist of sludge from municipal sewage treatment works. The management of the sludge has earlier been a problem at fertilizations, but now there is a method to produce sludge pellets that are easy to handle, possible to store and do not smell or contain any infectious matter. Before the sludge pellets can be used in a large scale, questions about the release of different matters from the sludge, should be answered. The aim of this study was to find out at which rate nutrients and heavy metals are released from sludge pellets spread on forest soils. The study was executed at Hjuleberg, east of Falkenberg in south Sweden. Pellets were put out in bags of fine-meshed synthetic fibre net. The bags were collected at four different occasions. The samples were analyzed for C, N, P, K, Ca, Mg, S, Al, As, B, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Na, Ni, Pb, Se, V and Zn. After nine months, about half of the original dry-matter and about half of the original amounts of N, K, Ca, Mg and S remained. The results showed that nitrogen was mineralized, which indicates that pelleted sludge can work as a source of nutrients, and that phosphorus was to a large part immobilized. As for As, Cd, Fe, Pb, Se and Zn, there was an enrichment in the pellets during the early winter, before the first uptake. Spreading of sludge of the kind that is used in this study results in spreading of heavy metals. Swedish limits of heavy metals in arable land might be exceeded during an initial phase, but is managed at an annual spreading of 0.85 tons of pelleted sludge per hectare, when using the kind of sludge that has been tested in this study.

    Full Text Available The paper investigates the phenomenon of foreignness and its understanding in ethnographic and philosophical context. The role of a phenomenologicalhermeneutic conception of text and action in bridging the gap between the native’s and the observer’s points of view with respect to the description of cultural phenomena is elucidated by way of comparing the theories of anthropologist Clifford Geertz and philosopher Paul Ricoeur. Hidden links between the two authors, who make sparse references to one another, but should be connected more thoroughly, are followed. The methods of “thick description” (Geertz and of taking the “text as a model” (Ricoeur for understanding social and cultural performances are analysed to attain a new notion of culture as context.

  4. Two-parameter quantum affine algebra Ur,s(sln-circumflex), Drinfeld realization and quantum affine Lyndon basis

    We further find the defining structure of a two-parameter quantum affine algebra U r,s (sl n -circumflex) (n > 2) in the sense of Benkart-Witherspoon [BW1] after the work of [BGH1], [HS] and [BH], which turns out to be a Drinfeld double. Of more importance for the 'affine' cases is that we work out the compatible two-parameter version of the Drinfeld realization as a quantum affinization of U r,s (sl n ) and establish the Drinfeld isomorphism Theorem in the two-parameter setting via developing a new remarkable combinatorial approach - quantum 'affine' Lyndon basis with an explicit valid algorithm, based on the Drinfeld realization.

  5. Die Kritik am transzendentalen Ich: Zu Sartres und Ricœurs Heidegger-Lektüren

    Directory of Open Access Journals (Sweden)

    Yvanka B. Raynova

    2015-08-01

    According Otto Pöggeler Heidegger's main brake with Husserl consists in his rejection of the tran-scendental constitution conceived as the life of an "absolute Cogito," replaced by Heidegger by the "factual life" from which phenomenology should always begin. The author of this paper argues that the problem about the starting point of phenomenology also appears later in the debates between Heidegger and Sartre, as well as in Ricoeur's Heidegger interpretation. Thus, the aim of the article is to analyze to what extent the positions of Heidegger, Sartre, and Ricoeur contradicts or even exclude each other, and to what extent they cross or eventually complement each other. The inquiry shows that Heidegger's accusation of Sartre's forgetting of the question about the sense of being of Dasein is unjustified. Equally untenable is Sartre's critique of Heidegger, that he had bypassed the Cogito as a starting point of the existential analysis, because Sartre's transcendence of the Cogito, which pretends to involve the transphenomenal Being, cannot be derived from it and risks to fall again in the trap of "phenomenalism," which Sartre reproached to Husserl. Ricoeur's Heidegger interpretation brings clarity to this discussion by pulling together the decentration of the subject and the limits of apodicticity of the Cogito. But his elaboration of the hermeneutics of the Self contains the risk of a hyperbolization of the role of language.

    2017-01-01

    The Osamu Utsumi Mine - MOU, belonging to the Brazilian Nuclear Industries - INB, began in 1977 with pickling activities and remained in operation until 1995. During this period, 94 million tons of rocks were removed, which caused the generation of large wasted rock piles. The intense drainage and precipitation in the study region favored the oxidation and leaching of the wasted rock piles, causing the Acid Drainage of Mine - DAM and generating effluents with low pH and high concentrations of fluoride, aluminum, iron, manganese, sulfate, zinc, uranium and Radio, among others. Currently the MOU is in the process of decommissioning and environmental remediation. The understanding of the hydrogeochemical processes and the behavior of the water flow through different aquifers is extremely important so that the actions of environmental remediation and control of the DAM are really effective. In this sense, in this work, geoprocessing and hydrochemical techniques were used to propose a conceptual hydrogeochemical model in the MOU cavity system and wasted rock pile number 4 - BF4. The geoprocessing techniques allowed to characterize and size the area under study and to integrate information on geology and mineralogy with the hydrochemical data. The hydrochemical studies were based on three groundwater sampling campaigns, using the low flow method in 17 monitoring wells, as well as 3 water reservoirs in the study area. In the collected samples were determined: (1) the main cations and anions for groundwater classification using Piper and Stiff diagrams and multivariate statistical methods (cluster and Principal Component Analysis); (2) the major long half radionuclides and 222 Rn to assess radioactivity and imbalance between them; (3) the stable isotopes of 18 O and 2 H to provide information on the underground flows and water source; (4) the Tritium values found in the samples to estimate the age of the groundwater; (V) the sulfur and oxygen isotopes present in the dissolved sulfate to provide information on pyrite oxidation and DAM generation processes. In addition, the potentiometric surface of the aquifers was elaborated and the hydraulic conductivity of the monitoring wells was calculated by the low flow method. The hydrogeochemical modeling consisted only in the speciation of the dissolved ions and determination of the saturation indexes of the main minerals in each sample, elaborated by the PHREEQC program. Finally, the conceptual hydrogeological model aimed to systematize and simplify the information generated in this work. (author)

    Full Text Available La représentation que les femmes ont d’elles-mêmes et du monde va indéniablement conditionner leurs engagements dans la République des mâles. Or dans l’échelle de ses objectifs, la femme antillaise ne fait pas de son engagement militant une priorité. Certes, le contexte culturel dans lequel elle évolue n’est pas étranger à cette posture qu’elle adopte. Cependant, de façon paradoxale, elle se distingue par ses capacités d’entreprendre et de réussir dans le monde des affaires. Sans doute une longue tradition de débrouillardise pour la survie de sa progéniture et d’elle-même, en d’autre terme pour l’oikonomia, constituerait la matrice d’une telle compétence économique.The view that women have of themselves and of the world  undoubtedly conditions their commitments to the “Republic of males”. In its list of priorities,  the Caribbean woman does not exhibit a militant commitment to sex equality. Certainly, the cultural context in which  women live does not encourage this stance. Nevertheless, paradoxically, Caribbean women are able to succeed and prosper in the business world.  Perhaps a long tradition of resourcefulness for the survival of her offspring and of herself , in other words for the oikonomia, constitutes the basis for such an economic competence.

    Full Text Available A number of aversive and appetitive unconditioned stimuli (such as shock and food are known to produce memory enhancement when they occur during the post-training period. Post-training exposure to conditioned aversive stimuli has also been shown to enhance memory consolidation processes. The present study shows for the first time that post-training exposure to conditioned stimuli previously paired with consumption of a sucrose solution also enhances memory consolidation. Male Long Evans rats were trained on a one-session conditioned cue preference (CCP task on a radial arm maze. Immediately or 2 hours after training, rats consumed a sucrose solution or were exposed to cues previously paired with consumption of sucrose or cues previously paired with water. Twenty-four hours later, the rats were tested for a CCP. Immediate, but not delayed, post-training consumption of sucrose enhanced memory for the CCP. Immediate, but not delayed, post-training exposure to cues previously paired with sucrose, but not with water, also enhanced CCP memory. The possibility that rewarding and aversive conditioned stimuli affect memory by a common physiological process is discussed.

    Variable concentrations of uranium occur naturally in waters, plant products and soils. Small amounts of this element are routinely incorporated by man. Occupationally exposed individuals (IOEs) are subject to the incorporation of higher amounts of uranium into their work routines. The effects on human health resulting from the incorporation of uranium in environmental doses are not very well established and are currently recognized as of little relevance. The incorporation resulting from occupational activities, where higher doses can be found, represents a health risk resulting from chemical damages to the kidneys. Considering that uranium is eliminated from the human body through urine and feces, and that the concentration in the urine can be obtained by means of radiochemical analyzes, this can be considered an efficient indirect method to verify the incorporation of this element. In the work the isotopes of {sup 234}U, {sup 235}U and {sup 238}U were analyzed in urine samples of IOEs and the rate of uranium present in them was verified.

    Full Text Available A study was carried out on the urea geometries using ab initio calculation and Monte Carlo computational simulation of liquids. The ab initio calculated results showed that urea has a non-planar conformation in the gas phase in which the hydrogen atoms are out of the plane formed by the heavy atoms. Free energies associated to the rotation of the amino groups of urea in water were obtained using the Monte Carlo method in which the thermodynamic perturbation theory is implemented. The magnitude of the free energy obtained from this simulation did not permit us to conclude that urea is non-planar in water.

    The gas is led in a controlled flow to a vertical reactor shaft with a circulating fluidized bed containing dispersed calcined limestone. The biomass is pyrolyzed by means of the reactor heat in order to produce tarry gas and charcoal. While the gas flows upward in the reactor shaft the tar is gasified in a heterogeneous catalytic reaction with limestone. Charcoal and limestone are separated from the gas at the top of the reactor shaft and brought back to the fluidized bed for combustion. (L.F.).

On the way to the places the same paths were used every day. Within the places different parts were used for normal preschool activities like eating, sleeping or playing. When the staff dramatized and the children played fantasy play the places were loaded with symbolic meanings. All these practices contributed to the process where the places were given identity.

    Full Text Available Cette contribution analyse les perceptions que les internautes des sites Forum Bonaberi.com et Cameroon-Info.Net ont du camfranglais, né du processus d’acclimatement/acclimatation du français au Cameroun. Mettant à contribution les discours des camfranglophones, l’approche glottonomique et l’imaginaire linguistique, l’étude se focalise sur les représentations systémiques et sociolinguistiques du camfranglais. S’agissant du premier axe, l’analyse des interventions discursives révèle les spécificités linguistiques du camfranglais, en l’opposant au pidgin-english-camerounais né de l’anglais et aux variétés de français parlé au Cameroun. Le second axe examine l’imaginaire de la variation sociolangagière du camfrançais. Il en découle que les internautes ont une saisie variationniste de cet parler selon trois niveaux : diachronique, diatopique et diaphasique. Ce camfranglais apparaît dans les discours épilinguistiques analysés comme une langue à part entière : d’où la revendication de ses statuts et ses fonctions officiels ; voire sa prise en compte glottopolitique. Toutes ces représentations faites par ce qu’on peut appeler les acteurs glottonomiques profanes permettent d’aboutir à la conclusion selon laquelle la gestion des problématiques glottopolitiques doit tenir compte de toutes les composantes sociales, pour un développement durable, stimulé par des langues. Par ailleurs, relativement à la linguistique française, cette analyse permet de saisir les tensions sociolinguistiques et les modalités de représentations impliquant le français et le camfranglais. Si le français constitue une langue matrice pour le camfranglais, il ressort de cette réflexion que ses locuteurs construisent des représentations visant à établir une frontière linguistique et sociolinguistique entre la langue mère (français et le camfranglais dérivé.

    The electricity market is deregulated. This means that all electricity customers are free to choose their electricity supplier. Many utilities market renewable electricity products such as wind power or hydroelectric power, saying that the customer makes a contribution to the environment by choosing these products. But is that really true? In this report, four researchers and consultants give an account of their views on how environmental valuation of electricity should be made. Specifically they discusses the driving forces for the development of the electricity system and the purchase of environmentally certified electricity and the link to environmental benefits. An important objective is to provide guidance as to how individuals and businesses through their actions can contribute to sustainable development

    Flow of organic carbon (OC) and nitrogen through a sea cage trout farm was calculated on the basis of detailed studies of the farming operation, water circulation, OC and nutrient transport and recycling processes in sediment. A third of the OC and nitrogen provided by fish food was incorporated...... derived from fish food settled on the seabed, where it was either mineralized or accumulated in the sediment. Based on transect measurements of diagenetic activity, the farm footprint was found to cover an area ~10 times the farm area. OC mineralization in the sediment increased linearly with increasing...

    Full Text Available Research has shown that prejudice and negative attitudes toward those who are experiencing mental illness are widespread, but those attitudes reduce the quality of life and recovery of individuals experiencing such problems. In this article, we use a survey to evaluate the extent and causes of negative attitudes among the public in three countries: Iceland, the United States, and Germany. Our results indicate the existence of widespread prejudice and negative attitudes in all three countries. We also show that people across the three countries are more negative toward individuals experiencing mental illness if they define the condition as an illness. Finally, the results indicate that prejudice and negative attitudes toward this group are less common in Iceland and in Germany than in the United States.

  20. Waste Generator Instructions: Key to Successful Implementation of the US DOE's 435.1 for Transuranic Waste Packaging Instructions (LA-UR-12-24155) - 13218

    French, David M.; Hayes, Timothy A.; Pope, Howard L.; Enriquez, Alejandro E.; Carson, Peter H.

    2013-01-01

    In times of continuing fiscal constraints, a management and operation tool that is straightforward to implement, works as advertised, and virtually ensures compliant waste packaging should be carefully considered and employed wherever practicable. In the near future, the Department of Energy (DOE) will issue the first major update to DOE Order 435.1, Radioactive Waste Management. This update will contain a requirement for sites that do not have a Waste Isolation Pilot Plant (WIPP) waste certification program to use two newly developed technical standards: Contact-Handled Defense Transuranic Waste Packaging Instructions and Remote-Handled Defense Transuranic Waste Packaging Instructions. The technical standards are being developed from the DOE O 435.1 Notice, Contact-Handled and Remote-Handled Transuranic Waste Packaging, approved August 2011. The packaging instructions will provide detailed information and instruction for packaging almost every conceivable type of transuranic (TRU) waste for disposal at WIPP. While providing specificity, the packaging instructions leave to each site's own discretion the actual mechanics of how those Instructions will be functionally implemented at the floor level. While the Technical Standards are designed to provide precise information for compliant packaging, the density of the information in the packaging instructions necessitates a type of Rosetta Stone that translates the requirements into concise, clear, easy to use and operationally practical recipes that are waste stream and facility specific for use by both first line management and hands-on operations personnel. The Waste Generator Instructions provide the operator with step-by-step instructions that will integrate the sites' various operational requirements (e.g., health and safety limits, radiological limits or dose limits) and result in a WIPP certifiable waste and package that can be transported to and emplaced at WIPP. These little known but widely productive Waste Generator Instructions (WGIs) have been used occasionally in the past at large sites for treatment and packaging of TRU waste. The WGIs have resulted in highly efficient waste treatment, packaging and certification for disposal of TRU waste at WIPP. For example, a single WGI at LANL, combined with an increase in gram loading, resulted in a mind boggling 6,400% increase in waste loading for 238 Pu heat source waste. In fact, the WGI combined with a new Contact Handled (CH) TRU Waste Content (TRUCON) Code provided a massive increase in shippable wattage per Transuranic Package Transporter-II (TRUPACT-II) over the previously used and more restrictive TRUCON Code that have been used previously for the heat source waste. In fact, the use of the WGI process at LANL's TA-55 facility reduced non-compliant drums for WIPP certification and disposal from a 13% failure rate down to a 0.5% failure rate and is expected to further reduce the failure rate to zero drums per year. The inherent value of the WGI is that it can be implemented in a site's current procedure issuance process and it provides documented proof of what actions were taken for each waste stream packaged. The WGI protocol provides a key floor-level operational component to achieve goal alignment between actual site operations, the WIPP TRU waste packaging instructions, and DOE O 435.1. (authors)

    This document constitutes an addendum to the September 1998, Closure Report for Corrective Action Unit 404: Roller Coaster Lagoons and Trench, Tonopah Test Range, Nevada as described in the document Recommendations and Justifications for Modifications for Use Restrictions Established under the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office Federal Facility Agreement and Consent Order (UR Modification document) dated February 2008. The UR Modification document was approved by NDEP on February 26, 2008. The approval of the UR Modification document constituted approval of each of the recommended UR modifications. In conformance with the UR Modification document, this addendum consists of: • This cover page that refers the reader to the UR Modification document for additional information • The cover and signature pages of the UR Modification document • The NDEP approval letter • The corresponding section of the UR Modification document This addendum provides the documentation justifying the modification of the UR for CAS TA-03-001-TARC Roller Coaster Lagoons. This UR was established as part of Federal Facility Agreement and Consent Order (FFACO) corrective actions and was based on the presence of contaminants at concentrations greater than the action levels established at the time of the initial investigation (FFACO, 1996; as amended August 2006). Since this UR was established, practices and procedures relating to the implementation of risk-based corrective actions (RBCA) have changed. Therefore, this UR was re-evaluated against the current RBCA criteria as defined in the Industrial Sites Project Establishment of Final Action Levels (NNSA/NSO, 2006c). This reevaluation consisted of comparing the original data (used to define the need for the UR) to risk-based final action levels (FALs) developed using the current Industrial Sites RBCA process. The re-evaluation resulted in a recommendation to modify the UR for CAS TA-03

    This study investigated the anticonvulsant effect of Uncaria rhynchophylla (UR) and the physiological mechanisms of its action in rats. A total of 70 male Sprague-Dawley (SD) rats were selected for study. Thirty four of these rats were divided into 5 groups as follows: 1) CONTROL GROUP (n = 6): received intraperitoneal injection (i.p.) of kainic acid (KA, 12 mg/kg); 2) UR1000 group (n = 10), 3) UR500 group (n = 6) 4) UR250 group, received UR 1000, 500, 250 mg/kg i.p. 30 min prior to KA administration, respectively; 5) Contrast group: received carbamazepine 20 mg/kg i.p. 30 min prior to KA administration. Behavior and EEG were monitored from 15 min prior to drug administration to 3 hours after KA administration. The number of wet dog shakes were counted at 10 min intervals throughout the experimental course. The remaining 36 rats were used to measure the lipid peroxide level in the cerebral cortex one hour after KA administration. These rats were divided into 6 groups of 6 rats as follows: 1) Normal group: no treatment was given; 2) CONTROL GROUP: received KA (12 mg/kg) i.p.; 3) UR1000 group, 4) UR500 group, 5) UR250 group, received UR 1000, 500, 250 mg/kg i.p. 30 min prior to KA administration, respectively; 6) Contrast group: received carbamazepine 20 mg/kg i.p. 30 min prior to KA administration. Our results indicated that both UR 1000 and 500 mg/kg decreased the incidence of KA-induced wet dog shakes, no similar effect was observed in the UR 250 mg/kg and carbamazepine 20 mg/kg group. Treatment with UR 1000 mg/kg, 500 mg/kg, or 250 mg/kg and carbamazepine 20 mg/kg decreased KA-induced lipid peroxide level in the cerebral cortex and was dose-dependent. These findings suggest that the anticonvulsant effect of UR possibly results from its suppressive effect on lipid peroxidation in the brain.

    A comparative study of the mass balance and production costs of uranium oxide fuels was carried out for an AP1000 reactor and thorium-uranium mixed oxide in a reactor proposal using thorium called AP-Th1000. Assuming the input mass values for a fuel load the average enrichment for both reactors as well as their feed mass was determined. With these parameters, the costs were calculated in each fuel preparation process, assuming the prices provided by the World Nuclear Association. The total fuel costs for the two reactors were quantitatively compared with 18-month open cycle. Considering enrichment of 20% for the open cycle of mixed U-Th oxide fuel, the total uranium consumption of this option was 50% higher and the cost due to the enrichment was 70% higher. The results show that the use of U-Th mixed oxide fuels can be advantageous considering sustainability issues. In this case other parameters and conditions should be investigated, especially those related to fuel recycling, spent fuel storage and reduction of the amount of transuranic radioactive waste.

    Uncaria rhynchophylla (Miq) Jack (UR) is one of many Chinese herbs. Our previous studies have shown that UR has both anticonvulsive and free radical-scavenging activities in kainic acid (KA)-treated rats. The aim of the present study was to use the effect of UR on activated microglia, nitric oxide synthase, and apoptotic cells to investigate its function in neuroproction in KA-treated rats. UR of 1.0 or 0.5 g/kg was orally administered for 3 days (first day, second day, and 30 min prior to KA administration on the third day), or 10 mg/kg (intraperitoneal injection, i.p.) N-nitro-L-arginine methyl ester (L-NAME) 30 min prior to KA (2 microg/2 microl) was injected into the right hippocampus region of Sprague-Dawly rats. ED1 (mouse anti rat CD68), neuronal nitric oxide synthase (nNOS), inducible nitric oxide synthase (iNOS) immunoreactive cells and apoptotic cells were observed in the hippocampus region. The results indicated that 1.0 g/kg, 0.5 g/kg of UR and 10 mg/kg of L-NAME reduced the counts of ED1, nNOS, iNOS immunoreactive cells and apoptotic cells in KA-treated rats. This study demonstrates that UR can reduce microglia activation, nNOS, iNOS and apoptosis, suggesting that UR plays a neuro-protective role against neuronal damage in KA-treated rats.

    Full Text Available On January 7, 1933, two years before Gershwin’s Porgy and Bess, The Emperor Jones, composed by Louis Gruenberg in 1931, had its world premiere at the Metropolitan Opera of New York. Although Gruenberg’s opera looks like a mere musical adaptation of O’Neill’s acclaimed play, first performed in 1920, some alterations made by the composer allow to question its ambivalent reception by the audience and the critics. Apart from the singular choice of O’Neill’s play and Gruenberg’s special interest in African American music and vocal traditions, this paper analyses the influence of the Harlem Renaissance period and the fantasmatics of race, present in both the play and the opera, albeit exacerbated in the latter through the scopic enjoyment of the body of the black Other.

    Full Text Available This article indicates a reflective paradigm generally ignored in feminist research regarding the sex/gender debate, as presented in the work of Judith Butler (Gender Trouble.  First, I address the fact that Butler’s philosophy is inscribed in the hermeneutical tradition of suspicion. Second, I put into relief the implicitly Platonic concept of mimesis, which is central to the anticipated subversion of gender, but uncriticized by Butler and others who follow her line of thought.  Third, since Butler’s feminism can’t ward off dualism, nor consider idem and ipse identity, I emphasize Paul Ricoeur ’s concept of triple mimesis and narrative identity, which allows us to depart from dichotomies and hierarchies.  Following the path of Ricoeur and Françoise Heritier, I finally defend a feminist hermeneutical point of view, which is differentialist and universal.

    Full Text Available L’article débat de la question de l’équité dans la lutte contre les changements climatiques. Il établit un parallèle entre le développement pris au niveau international de la négociation entre Etats d’une part, et la pauvreté au niveau d’une collectivité d’autre part. Dans les deux cas, il s’agit à la fois d’un principe moral essentiel, mais aussi d’une condition centrale des consensus et donc de la réussite des politiques face au défi climatique. La question de l’équité renvoie aussi très vite au changement nécessaire des modes de vie vers plus de sobriété.The article debates Equity Issues in the Climate Change debate is debated. A parallel is set between the development issues at the international level of negotiations between States, and poverty alleviation at the local community level. In both cases, the discussions stem from an essential moral principle, but also as a requisite for consensus and thus a condition of success of climate change policies to combat Climate Change. The issue of equity brings also forward the necessary modification of consumption patterns, into more frugal modes.

    Full Text Available Study on environmental factors influencing the urea content of cow's milk in Wallonia and estimation of nitrogen rejection. In Wallonia (South of Belgium, the urea content of milk produced on farms is assessed by the "Comité du lait". A total of 8,295,337 pieces of data recording the urea content in milk tanks was collected on Walloon farms in 2000 and during the period 2002-2011. These data were analyzed using a linear model. The fixed effects of the agricultural area or vulnerable zone, the month, the year and the interactions between these parameters were included in the model. The levels of fat and protein content in the milk were used as covariates. The average urea content in milk was found to be 255 mg·l-1. Four percent of the observations recorded a urea content of over 350 mg·l-1 and 14% recorded a urea content of over 400 mg·l-1. The models explained 38% and 35% of the variation in milk urea for the agricultural area and the vulnerable area variables, respectively. Within these models, the variables of month, region, year and the month-year interaction were the components that provided the most information. Milk urea content was higher in the summer period – April to October – than during the winter period – November to March – (287 vs 210 mg·l-1. This observation can be explained by the change in the cows' diet. During the summer, most of the cows grazed; ingestion of grass can lead to a nitrogen surplus in the diet. In the so-called "Limoneuse" and "Sablo-limoneuse" agricultural areas, recorded urea content was lower than in "Ardenne" and "Haute-Ardenne" (223 and 220 mg vs 278 and 284 mg·l-1, respectively. This difference can be explained by a greater use of grass in the diet in Ardenne and Haute-Ardenne. In vulnerable areas, urea content was lower (236 vs 273 mg·l-1. Annual nitrogen production calculated using different prediction equations ranged from 82 to 119 kg N per cow depending on the agricultural area.

    The cleanup and re-industrialization of the East Tennessee Technology Park (ETTP) hinges on a collaborative working relationship between the cleanup contractor and the U.S. Department of Energy's (DOE)-Oak Ridge Office (ORO). A Partnering Framework document was signed on June 30, 2011, with an ultimate goal of completing the contract scope of work ahead of schedule and under budget. This partnering process was the first time that DOE and its contractor, jointly developed and signed such an agreement before the contractor assumed management responsibilities of the Site. A strong desire of both parties to utilize a partnering approach in the performance of their respective responsibilities is evident. The Partnering Framework was modeled after a partnering process employed by the California Department of Transportation, Division of Construction. This partnering process has been used successfully by the California Department of Transportation and its major contractors for many years with great success. The partnering process used at ETTP was a phased approach. First, a Partnering Framework document was developed and signed June 30, 2011, by the Partnering Sponsors, the two leaders of the ETTP cleanup and re-industrialization project, the DOE-ORO Assistant Manager for Environmental Management and the contractor's President and Program Manager. In this way the partnering process could begin when the contactor assumed ETTP Site management responsibilities on August 1, 2011. The Partnering Framework then set the stage for the second phase of the partnering process which would be development of the Partnering Agreement and the kick-off of the first of a number of facilitated Partnering Workshops. Key elements of the Partnering Framework document include: (1) a statement of commitment which affirms the desire of both parties to work collaboratively toward the cleanup and re-industrialization of the ETTP Site; (2) a vision which describes both parties ultimate goal of safe, efficient cleanup, and (3) an implementation section which describes how the partnering process will be conducted, as well as how disputes will be managed. The signed Partnering Framework and Partnering Agreement provide the needed foundation of the safe and cost-effective cleanup and re-industrialization of the ETTP Site. The benefits of partnering have already been observed as the Partnering Teams effectively addressed a number of early contract and project challenges such as funding reductions and progress in resolving Material Differences. Based, in part of the successes achieved as a result of the partnering between UCOR and DOE-ORO, UCOR and DOE-ORO are extending this partnering approach to a number of the ETTP Site stakeholders. For example, DOE-ORO, UCOR and CROET signed a Partnering Agreement on November 3, 2011. This Partnering Agreement affirms the parties' commitment to work collaboratively to re-industrialize the ETTP Site. Both DOE-ORO and UCOR are looking to extend this partnering approach with other Site stakeholders such as its employees, its subcontractors, the Oak Ridge National Laboratory and the Y-12 Security Complex in the future.

    Acid mine drainage (AMD) is a process that occurs in many mining that have sulfide ores. With water and oxygen, several metals are oxidized, one example being uranium. At the mine pit of the Osamu Utsumi Mine located at INB - Caldas and in two other boot-wastes (mining waste pile), AMD is present and currently, without a technological solution. The acidic water present in the pit is treated with hydrated lime, generating water for disposal and an alkaline residue called calcium diuranate - DUCA. The DUCA has a concentration of approximately 0.32% U{sub 3}O{sub 8}, which makes interesting the development of a process for extracting that metal. One of the processes that can be used is leaching. For this study, it was decided to evaluate the alkaline leaching to extract the uranium present in the residue. It is necessary to optimize operational parameters for the process: percentage of solids, concentration of leaching agent in solution, temperature and reaction time. With these parameters, it is possible to improve the leaching so that the largest amount of uranium is extracted from the sample, to help solve the environmental impact caused by the wastewater from the treatment of acid waters and, in addition, to give an economical destination for this metal that is contained in the deposited DUCA.

  12. Competitiveness of grid-connected solar electricity in Sweden - as seen from the perspective of the utilities and the net owners; Konkurrenskraft foer naetansluten solel i Sverige - sett ur kraftfoeretagens och naetaegarnas perspektiv

    The objective of this report was to analyse the competitiveness of grid-connected solar power in Sweden - and specifically the competitiveness for energy companies and net owners. In theory, solar power could to a large extent fulfil the electricity demand in Sweden, especially in the summer. However, the high cost of solar cells is a major barrier to implementation. Future technology development and increased efficiency could, however, lead to important cost reductions. The question is if such expected cost reductions would make grid-connected solar power a preferable investment option for energy companies and an interesting alternative for the net owners. The results of the study show that solar power will not be a competitive alternative for the energy companies in Sweden, not in 2020 and probably not in 2050. Other alternatives such as new investments in wind turbines and bio-mass based technology options will be producing electricity at a lower cost. Moreover, solar power will have an unfavourable production profile, generating power in the summertime when less needed. However, by using the reservoirs of the hydro power systems in Sweden as storage capacity, approximately 5 TWh solar power could be allowed in the Swedish electricity system. The results of the study indicate that solar power could have a positive effect on the electricity distribution system since distributed generation will result in lower losses in the system. Moreover, solar power will be produced during daytime when the electricity demand will peak. One of the main challenges for the net owners would be to design the net in such a way that the net and the solar cells could work together in the best possible way. Another challenge would be the high cost for connecting the solar cells to the grid; this cost needs to be reduced. Looking instead at the house-owners as possible investors, solar cells appear as a much more attractive alternative for the future, the value of the solar power is higher for the house-owner at the same time as the cost is lower. The calculated cost is as low as 1 SEK/kWh in 2050 assuming a top rated power of 7 kW. In all, the report shows that solar power will not be a competitive alternative for energy companies in the near future. The net owners will also confront challenges and high cost related to the connection of the solar cells to the grid. In the near term, the interest in investing in solar cells will be associated with house-owners. In a longer time perspective, the development will be much more uncertain. Climate change may force us to invest more in technologies such as solar cells, which in turn may lead to new innovative technology options and new types of solar cells. This may lead to drastic cost reductions and the use of solar cells in conventional technologies such as solar protection devices, windows and facades.

  13. Erosion and Deposition Monitoring Using High-Density Aerial Lidar and Geomorphic Change Detection Software Analysis at Los Alamos National Laboratory, Los Alamos New Mexico, LA-UR-17-26743

    The Los Alamos National Laboratory storm water program installed sediment transport mitigation structures to reduce the migration of contaminants within the Los Alamos and Pueblo (LA/P) watershed in Los Alamos, NM. The goals of these structures are to minimize storm water runoff and erosion, enhance deposition, and reduce mobility of contaminated sediments. Previous geomorphological monitoring used GPS surveyed cross-sections on a reach scale to interpolate annual geomorphic change in sediment volumes. While monitoring has confirmed the LA/P watershed structures are performing as designed, the cross-section method proved difficult to estimate uncertainty and the coverage area was limited. A new method, using the Geomorphic Change Detection (GCD) plugin for ESRI ArcGIS developed by Wheaton et al. (2010), with high-density aerial lidar data, has been used to provide high confidence uncertainty estimates and greater areal coverage. Following the 2014 monsoon season, airborne lidar data has been collected annually and the resulting DEMs processed using the GCD method. Additionally, a more accurate characterization of low-amplitude geomorphic changes, typical of low-flow/low-rainfall monsoon years, has been documented by applying a spatially variable error to volume change calculations using the GCD based fuzzy inference system (FIS). The FIS method allows for the calculation of uncertainty based on data set quality and density e.g. point cloud density, ground slope, and degree of surface roughness. At the 95% confidence level, propagated uncertainty estimates of the 2015 and 2016 lidar DEM comparisons yielded detectable changes greater than 0.3 m - 0.46 m. Geomorphic processes identified and verified in the field are typified by low-amplitude, within-channel aggradation and incision and out of channel bank collapse that over the course of a monsoon season result in localized and dectetable change. While the resulting reach scale volume change from 2015 - 2016 was often nonsignificant, it is estimated with a higher degree of confidence than the previous cross-section/interpolation method. Results from comparisons of the recent low-intensity rainfalls/storm peak discharges monsoon season DEMs have established the expected amount of geomorphic change to be minor and localized, yet demonstrable.

    Full Text Available A spectrophotometric flow injection analysis (FIA procedure employing natural urease enzyme source for the determination of urea in animal blood plasma was developed. Among leguminous plants used in the Brazilian agriculture, the Cajanus cajan specie was selected as urease source considering its efficiency and availability. A minicolumn was filled with leguminous fragments and coupled to the FIA manifold, where urea was on-line converted to ammonium ions and subsequently it was quantified by spectrophotometry. The system was employed to determine urea in animal plasma samples without any prior treatment. Accuracy was assessed by comparison results with those obtained employing the official procedure and no significant difference at 90 % confidence level was observed. Other profitable features such as an analytical throughput of 30 determinations per hour, a reagent consumption of 19.2 mg sodium salicylate, 0.5 mg sodium hipochloride and a relative standard deviation of 1.4 % (n= 12 were also obtained.

  2. Electricity use and load management in electricity heated one-family houses from customer and utility perspective; Effekten av effekten - Elanvaendning och laststyrning i elvaermda smaahus ur kund- och foeretagsperspektiv

    Until recently, the increase in electricity demand and peak power demand has been met by expansion of the electricity production. Today, due to the deregulation of the electricity market, the production capacity is decreasing. Therefore, there is a national interest in finding solutions to peak problems also on the demand side. In the studies described here (Study 1 and 2) ten households in electrically heated houses were examined. In 1999 the utility equipped their customers with a remote metering system (CustCom) that has an in-built load control component. In Study 1, the load pattern of ten households was examined by using energy diaries combined with frequent meter readings (every five minutes) of the load demand for heating, hot water service and domestic electricity use. Household members kept energy diaries over a four-day period in January 2004, noting time, activities and the use of household appliances that run on electricity. The analysis showed that the use of heat-producing household appliances, e.g. sauna, washing machine and dryer, appliances used for cooking, dishwasher and extra electric heaters, contribute to the household's highest peaks. Turning on the sauna and at the same time using the shower equates to a peak load of 7-9 kW. This, in addition to the use of electricity for heating and lighting along alongside electricity use for refrigerators and freezers, results in some households reaching their main fuse level (roughly 13,8 kW for a main fuse of 20 A). This means that the domestic use of electricity makes up a considerable part of the highest peak loads in a household, but the highest peaks occur together with the use of electricity for heating and hot water. In the second study, Study 2, the households participated in a load control experiment, in which the utility was able to turn on and switch off the heating and hot water systems remotely, using the CustCom system. Heating and water heaters were switched off for periods of 1-4 hours without letting the households know when the control periods would take place or how long they would last. Household heating and hot water comfort as well as the households' attitudes towards and experiences of being controlled were investigated using a combination of methods. It could be concluded from the results of study 1 and 2, that both direct and indirect load control are, from the household perspective, possible measures to shift load demand from critical time periods.

    Directory of Open Access Journals (Sweden)

    Yasuhiko Sugimura

    2012-12-01

    Full Text Available In spite of his clear and deliberate distinction between philosophical and religious discourse, Ricoeur lets these two aspects of his thought interweave with respect to the deep "conviction" motiving it. The idea of “attestation”, considered as the "password" granting access to his last "hermeneutics of the self", testifies to this in particular. This term, while containing a religious connotation, refers to what Heidegger calls Fundamentalontologie, in which attestation (Bezeugung is totally de-theologized to indicate how Dasein assumes its own death. But Ricoeur only incorporates this notion into his thought by making it undergo a profound modification. Ricoeur replaces “being–toward–death” with “remaining alive until…”, which allows him to recognize “the religious in common.” How can we develop a conception of the philosophy of religion from this winding process?

    The Osamu Utsumi Mine - MOU, belonging to the Brazilian Nuclear Industries - INB, began in 1977 with pickling activities and remained in operation until 1995. During this period, 94 million tons of rocks were removed, which caused the generation of large wasted rock piles. The intense drainage and precipitation in the study region favored the oxidation and leaching of the wasted rock piles, causing the Acid Drainage of Mine - DAM and generating effluents with low pH and high concentrations of fluoride, aluminum, iron, manganese, sulfate, zinc, uranium and Radio, among others. Currently the MOU is in the process of decommissioning and environmental remediation. The understanding of the hydrogeochemical processes and the behavior of the water flow through different aquifers is extremely important so that the actions of environmental remediation and control of the DAM are really effective. In this sense, in this work, geoprocessing and hydrochemical techniques were used to propose a conceptual hydrogeochemical model in the MOU cavity system and wasted rock pile number 4 - BF4. The geoprocessing techniques allowed to characterize and size the area under study and to integrate information on geology and mineralogy with the hydrochemical data. The hydrochemical studies were based on three groundwater sampling campaigns, using the low flow method in 17 monitoring wells, as well as 3 water reservoirs in the study area. In the collected samples were determined: (1) the main cations and anions for groundwater classification using Piper and Stiff diagrams and multivariate statistical methods (cluster and Principal Component Analysis); (2) the major long half radionuclides and {sup 222}Rn to assess radioactivity and imbalance between them; (3) the stable isotopes of {sup 18}O and {sup 2}H to provide information on the underground flows and water source; (4) the Tritium values found in the samples to estimate the age of the groundwater; (V) the sulfur and oxygen isotopes present in the dissolved sulfate to provide information on pyrite oxidation and DAM generation processes. In addition, the potentiometric surface of the aquifers was elaborated and the hydraulic conductivity of the monitoring wells was calculated by the low flow method. The hydrogeochemical modeling consisted only in the speciation of the dissolved ions and determination of the saturation indexes of the main minerals in each sample, elaborated by the PHREEQC program. Finally, the conceptual hydrogeological model aimed to systematize and simplify the information generated in this work. (author)

    The purpose of this CR is to document that closure activities have met the approved closure standards detailed in the NDEP-approved CAP for CAU 271. The purpose of the Errata Sheet is as follows: In Appendix G, Use Restriction (UR) Documentation, the UR form and drawing of the UR area do not reflect the correct coordinates. Since the original UR was put into place, the UR Form has been updated to include additional information that was not on the original form. This Errata Sheet replaces the original UR Form and drawing. In place of the drawing of the UR area, an aerial photograph is included which reflects the UR area and the correct coordinates for the UR area.

    Uncaria rhynchophylla (UR), which is a traditional Chinese medicine, has anticonvulsive effect in our previous studies, and the cellular mechanisms behind this are still little known. Because of this, we wanted to determine the importance of the role of UR on kainic acid- (KA-) induced epilepsy. Oral UR for 6 weeks can successfully attenuate the onset of epileptic seizure in animal tests. Hippocampal mossy fiber sprouting dramatically decreased, while neuronal survival increased with UR treat...

    Cauchy inequality (CI) relates scalar products of two vectors and their norms. I point out other similar inequalities (SI). Starting with CI Schroedinger derived his uncertainty relation (UR). By using SI other various UR can be obtained. It is shown that they follow from the Schroedinger UR. Two generalizations of CI are obtained for mixed states described by density matrices. Using them two generalizations of UR for mixed states are derived. Both differ from the UR generalization known from the literature. The discussion of these generalizations is given

    To evaluate the characteristics and outcomes of ureteroscopy (URS) in children treated in several hospitals participating in the Clinical Research Office of the Endourological Society (CROES) Study, and to present the overall results of pediatric URS compared with adults. The CROES Study collected data on consecutive patients treated with URS for urolithiasis at each participating center over a 1-year period. The collected prospective global database includes data for 11,885 patients who received URS at 114 centers in 32 countries. Of these URS-treated patients, 192 were ≤18 years old. Of the 114 centers participating in the study, 42% had conducted pediatric URS. Among the pediatric cases, 7 were infants, 53 were small children, 59 were school-aged children, and 73 were adolescents. A considerable number (37%) of the pediatric cases had previously undergone URS treatment. No differences in the surgical outcomes of the adults and children were reported. The URS-treated children had a greater number of positive preoperative urine cultures when compared with adult cases treated. A semirigid scope was used in the vast majority of pediatric cases (85%). According to the present data, within the group of URS-treated children, the younger the child, the more readmissions occurred. URS is as efficient and safe in children as it is in adults. The data suggest that readmissions among URS-treated children are associated with age, with the likelihood of readmissions greater among younger age groups. Copyright © 2016 Elsevier Inc.

    To evaluate the efficacy of flexible ureterscopy (fURS) and extracorporal shockwave lithotripsy (SWL) in the treatment of urolithiasis, complemented by a subgroup analysis of lower pole calyx. Retrospective analysis of patients treated by fURS or SWL was performed by independent variables such as gender, age, nephrolith size, double-J stent (DJ stent) and stone localisation. Out of 326 patients, 165 were treated by SWL and 161 by fURS. Complete stone removal was achieved by fURS in 83.2% and by SWL in 43.0% (p auxillary DJ stent was performed more often preoperative before fURS. The subgroup analysis of lower pole calyx confirmed these evaluations. Complete stone-free removal was almost 8 times higher after fURS compared to SWL. The efficacy of fURS in treatment of urolithiasis is substantially higher than the efficacy of SWL. © 2015 S. Karger AG, Basel.

  12. Closure Report for Corrective Action Unit 574: Neptune, Nevada National Security Site, Nevada

    International Nuclear Information System (INIS)

    2012-01-01

    Corrective Action Unit (CAU) 574 is identified in the Federal Facility Agreement and Consent Order (FFACO) as 'Neptune' and consists of the following two Corrective Action Sites (CASs), located in Area 12 of the Nevada National Security Site: (1) CAS 12-23-10, U12c.03 Crater (Neptune); and (2) CAS 12-45-01, U12e.05 Crater (Blanca). This Closure Report presents information supporting closure of CAU 574 according to the FFACO (FFACO, 1996 [as amended March 2010]) and the Streamlined Approach for Environmental Restoration Plan for CAU 574 (U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office [NNSA/NSO], 2011). The following activities were performed to support closure of CAU 574: (1) In situ external dose rate measurements were collected using thermoluminescent dosimeters at CAS 12-45-01, U12e.05 Crater (Blanca). (2) Total effective dose rates were determined at both sites by summing the internal and external dose rate components. (3) A use restriction (UR) was implemented at CAS 12-23-10, U12c.03 Crater (Neptune). Areas that exceed the final action level (FAL) of 25 millirems per year (mrem/yr) based on the Occasional Use Area exposure scenario are within the existing use restricted area for CAU 551. The 25-mrem/yr FAL is not exceeded outside the existing CAU 551 UR for any of the exposure scenarios (Industrial Area, Remote Work Area, and Occasional Use Area). Therefore, the existing UR for CAU 551 is sufficient to bound contamination that exceeds the FAL. (4) An administrative UR was implemented at CAS 12-45-01, U12e.05 Crater (Blanca) as a best management practice (BMP). The 25-mrem/yr FAL was not exceeded for the Remote Work Area or Occasional Use Area exposure scenarios; therefore, a UR is not required. However, because the 25-mrem/yr FAL was exceeded for the Industrial Area exposure scenario, an administrative UR was established as a BMP. UR documentation is included as Appendix B.

    Full Text Available Seizures cause inflammation of the central nervous system. The extent of the inflammation is related to the severity and recurrence of the seizures. Cell surface receptors are stimulated by stimulators such as kainic acid (KA, which causes intracellular mitogen-activated protein kinase (MAPK signal pathway transmission to coordinate a response. It is known that Uncaria rhynchophylla (UR and rhynchophylline (RP have anticonvulsive effects, although the mechanisms remain unclear. Therefore, the purpose of this study is to develop a novel strategy for treating epilepsy by investigating how UR and RP initiate their anticonvulsive mechanisms. Sprague-Dawley rats were administered KA (12 mg/kg, i.p. to induce seizure before being sacrificed. The brain was removed 3 h after KA administration. The results indicate that pretreatment with UR (1.0 g/kg, RP (0.25 mg/kg, and valproic acid (VA, 250 mg/kg for 3 d could reduce epileptic seizures and could also reduce the expression of c-Jun aminoterminal kinase phosphorylation (JNKp of MAPK signal pathways in the cerebral cortex and hippocampus brain tissues. Proinflammatory cytokines interleukin (IL-1β, IL-6, and tumor necrosis factor-α remain unchanged, indicating that the anticonvulsive effect of UR and RP is initially involved in the JNKp MAPK signal pathway during the KA-induced acute seizure period.

    Sung Han Kim

    Full Text Available OBJECTIVE: Patients can experience urinary retention (UR after Holmium laser enucleation of the prostate (HoLEP that requires bladder distension during the procedure. The aim of this retrospective study is to identify factors affecting the UR after HoLEP. MATERIALS AND METHODS: 336 patients, which underwent HoLEP for a symptomatic benign prostatic hyperplasia between July 2008 and March 2012, were included in this study. Urethral catheters were routinely removed one or two days after surgery. UR was defined as the need for an indwelling catheter placement following a failure to void after catheter removal. Demographic and clinical parameters were compared between the UR (n = 37 and the non-urinary retention (non-UR; n = 299 groups. RESULTS: The mean age of patients was 68.3 (±6.5 years and the mean operative time was 75.3 (±37.4 min. Thirty seven patients (11.0% experienced a postoperative UR. UR patients voided catheter free an average of 1.9 (±1.7 days after UR. With regard to the causes of UR, 24 (7.1% and 13 (3.9% patients experienced a blood clot-related UR and a non-clot related UR respectively. Using multivariate analysis (p0.05. CONCLUSIONS: De novo UR after HoLEP was found to be self-limited and it was not related to learning curve, patient age, diabetes, or operative time. Efficient morcellation and careful control of bleeding, which reduces clot formation, decrease the risk of UR after HoLEP.

    Full Text Available Dans le cadre d’un débat, la représentation de propos peut être considérée comme une véritable « arme » rhétorique, tant le recours à ce procédé permet au locuteur de jouer de différentes retombées argumentatives. Aussi, à partir de la transcription de la rencontre entre Nicolas Sarkozy (NS et Ségolène Royal (SR lors du débat présidentiel de l’entre-deux tours de 2007, nous proposons-nous d’étudier les différentes formes de DR utilisées afin d’en dresser une typologie à visée argumentative. Pour ce faire, nous nous placerons dans une optique quelque peu divergente des classifications traditionnelles, puisque nous utiliserons la notion de « temporalité » — en tant que positionnement de l’énonciation de référence par rapport à l’intervention en cours — comme principal critère distinctif des occurrences et des effets dont celles-ci sont directement responsables. En plaçant de la sorte la temporalité au centre de l’étude des discours représentés (dorénavant DR, nous serons tout d’abord amenée à reconsidérer les critères traditionnellement pris en compte dans les classifications temporelles, avant de revenir sur l’importance de la nature des sources énonciatives de référence ; nous reviendrons en outre sur le critère de « virtualité » fréquemment utilisé comme un élément distinctif. Nous procéderons alors, dans le but d’expliquer au mieux la portée de chaque occurrence de DR, à un inventaire des diverses formes recensées, en conduisant pour chaque type de source énonciative une étude des différentes temporalités observables.

    In this study the life-cycle environmental impacts from an EPSPEX system for distribution of district heat (a four-pipe system with centrally generated hot tap water) are compared with the environmental impacts of a twin-pipe system with steel media pipes, if installed in the same area. A life cycle assessment of the EPSPEX system constructed in Vraaen, Vaernamo, Sweden, has been reported in FVF-FOU--2005-20. In that study the question was raised of how the EPSPEX system compares with a conventional twin-pipe system with polyurethane-insulated steel media pipes. In the present study the EPSPEX system in Vraaen is compared with a hypothetical construction of a conventional twin pipe system in the same area. Two different fuel mixes for district heat generation have been studied to increase the understanding of the environmental performance of district heat distribution systems; the fuel mix used in Vraaen (heat delivered from Vaernamo Energi) and Swedish average district heat. How media pipes from the two different materials (PEX and steel) compare is discussed in a separate part. There are technical differences that must be kept in mind when the systems are compared in this way. The EPSPEX system is designed for low-pressure district heat systems and could only be used in such context. It is unadvisable to install the EPSPEX system below the ground water table; this is not a restriction for the twin pipe system. Under the conditions of this study the environmental performance of the EPSPEX system is better than the twin pipe system. The heat loss from the EPSPEX system is approximately 60% of the heat loss for a comparable twin pipe system. This is caused by a combination of thick insulation for the EPSPEX system and the possibility to summertime shut down the district heating circuit for this system and only use the hot tap-water circuit. Note, however, that the heat loss from the EPSPEX system is more uncertain compared to the twin-pipe system. From the characterization methods used, the production of the EPSPEX system gives a higher environmental impact compared to the twin pipe system. This heavily depends on the large amount of insulating material used. However, the environmental impacts from production of the insulation are more then outweighed by the emissions avoided from heat generation due to lower heat loss. District heating sub centrals generates a notable part of the total environmental impact when using the weighing method EPS2000. Note that sub centrals are not technically necessary in low-pressure district heat systems, as the EPSPEX system. The comparison between different fuel mixes for heat generation indicates clearly that the heat generation is an important parameter for environmental performance for all district heating. It is further indicated that also biofuels must be used with sensible and environmentally friendly methods. The media pipes of PEX seem to give lower environmental impacts compared with media pipes of steel. However, the results differ between assessment methods used.

    The determination of the volumes of the sterile piles generated in the uranium mining and their respective characterization is of extreme importance for the management of mining wastes and future decommissioning actions of a nuclear facility. With the development of information technology, it becomes possible to simulate different scenarios in a computational environment, being able to store, represent and process data from existing information. In the industrial mining context, the sterile is represented with rocky materials of different granulometries and with ore content below the cut content determined by the industrial process. In this sense, the present work has the objective of calculating the volume of the sterile stacks of the Osamu Utsumi uranium mine of INB - Nuclear Industries of Brazil / Caldas. The MOU was officially inaugurated in 1977 and operated until 1995, where 1,200 tons of U{sub 2}O{sub 3} were produced generating about 94.5 x 106 tons of sterile material containing low levels of radioactive material and pyrite. The methodology for the development of this work initially involves integration approaches between the Geographic Information System (GIS) and terrain modeling for the sterile piles called BF4 and BF8. The results obtained were compared with the existing literature, translating the importance of GIS as a tool in the management of wastes.

    Full Text Available Cet article décrit les mécanismes du deuil et des funérailles en même temps qu’il s’interroge sur la place des conceptions relatives à la mort dans la culture des Sept Maisons de l’Ouest Gurāgē. La description des premiers nous permet de saisir la dynamique des rapports entre les différents segments de la société des Sept Maisons. L’analyse des secondes révèle que celles-ci jouent un rôle déterminant dans la constitution même des lignages, des clans, des maisons et des Sept Maisons : elles légitiment cette organisation du point de vue religieux. L’article tend ainsi à montrer que la mort constitue un thème central de l’histoire des populations de l’Ouest Gurāgē aux xixe et xxe siècles, et qu’elle peut être considérée comme un des moteurs de l’émergence et de l’épanouissement des Sept Maisons.The processes of bereavement and funerals are described while raising questions about death in the culture of the western Gurage “Seven Houses”. This description sheds light on the moving relations between different segments of this society. Conceptions about death play a decisive role in the formation of lineages, clans, households and the Seven Houses; they legitimate this social organization in religious terms. Death has been a key theme in the history of western Gurage peoples during the 19th and 20th centuries. It can be seen as a driving force in the emergence and development of the Seven Houses.

Závislost mezi běžně užívanými parametry aerobní zdatnosti (VO2max.kg–1, CTW a MPO a TS (% BF, FFM, BCM a ECM/BCM byla stanovena u 1235 dětí (756 chlapců a 479 děvčat ve věku 6 až 14 let. Aerobní zdatnost a tělesná výkonnost byly hodnoceny pomocí stupňovaného zatížení na běhacím koberci o stálém sklonu 5 %. Počáteční na věku závislá rychlost běhu byla zvyšována o 1 km.h–1 až do okamžiku subjektivního vyčerpání. Tělesné složení bylo hodnoceno pomocí celotělové bioimpedanční metody s využitím predikčních rovnic pro děti. Procento BF vykazovalo zápornou signifikantní korelaci s VO2max.kg–1 a CTW. Obojí jak FFM tak BCM pozitivně korelovalo s CTW, MPO a VO2max.kg–1. Koeficient ECM/BCM byl v negativním vztahu s VO2max.kg–1 a CTW. Závěrem lze konstatovat, že TS je významným funkčním determinantem v laboratorních podmínkách (zátěžový test na běhátku a v terénu (běžecký nebo chodecký test. Sledované proměnné, charakterizující TS, významně ovlivňují proměnné, které mohou definovat aerobní zdatnost. Výsledky dokládají, že jestliže není možné přímo měřit spotřebu kyslíku, lze k odhadu těchto proměnných využít parametrů tělesné výkonnosti a tělesného složení; toto může být velmi užitečné v případě velkých populačních studií. Body composition (BC may be used as a criterion of the actual biological state of children, in other words, their physical state of development. The aim of our study was to determine the interdependence of some body composition variables and aerobic fitness (VO2max.kg–1 and parameters of physical performance, ie. calculated total work (CTW and maximal power output (MPO on the treadmill in a group of Czech children and youth. The interdependence between frequently used indicators of aerobic fitness (VO2max.kg–1, CTW, and MPO, and BC (% BF, FFM, BCM and ECM/BCM were studied in a group of 1235 Czech children (756 boys and 479 girls aged from 6 to 14 years. Both aerobic fitness and physical performance variables were assessed by means of an incremental treadmill test with a constant slope of 5%. The age dependent initial speed was increased by 1 km.h–1 till subjective exhaustion. Body composition was determined by whole body bioimpedance measurements using a modified prediction equation for children. The percentage of BF was negatively correlated with VO2max.kg–1, and CTW. Both FFM and BCM were positively related to CTW, MPO, and VO2max.kg–1. The ECM/BCM relationship was negatively related to VO2max.kg–1 and CTW. In conclusion, BC is an important determinant of physical performance in the laboratory (treadmill exercise tests and in the field (running and/or walking tests. The BC parameters significantly influence the variables that could be used for characterisation of aerobic fitness. The results further demonstrate that when oxygen consumption is not feasible, physical performance characteristics together with parameters of BC seem to be a good predictor of aerobic fitness. This may be very helpful in large population studies.

    This study aimed to produce scientific and technical knowledge aiming at the development of techniques to immobilize the waste generated in the treatment of acid waters in the UTM-INB Caldas uranium mining and processing facility using Portland cement. This residue (calcium diuranate - DUCA) contains uranium compounds and metal hydroxides in a matrix of calcium sulfate. It is observed that this material, in contact with the lake of acid waters of the mine's own pit, undergoes resolubilization and, therefore, changes the quality of the acidic water contained therein, changing the treatment parameters. For the study of immobilization of this residue, the mass of water contained in both the residue deposited in the pit of the mine and in the pulp resulting from the treatment of the acid waters was determined. In addition, different DUCA / CEMENT / WATER ratios were used for immobilization and subsequent mechanical strength and leaching tests. The results showed that in the immobilized samples with 50% cement mass condition, no uranium was detected in the leaching tests, and the mechanical strength at compression was 9.4 MPa, which indicates that more studies are needed, but indicate a good capacity to immobilize uranium in cement.

    During a mine exploration the environment can be affected by different ways being one of them the mine acid drainage(DAM), that is formed by the exposition of sulphated minerals to the atmospheric air, water and iron-oxidation microorganisms. This exposition results in oxidation reactions and formation of sulphuric acid that dissolves all kind of metals present at the mineral that will result in the contamination of the ground and waters. The object of this research work is to test a technological solution of the mine acid drainage problem applying ozone advanced oxidation of the heavy metals present at the mine drainage of a uranium mine with special focus in the manganese removal. This study is applied to the material from the uranium mine of the Brazilian Nuclear Industry - INB, at Caldas- MG. The INB Industry has serious DAM contamination being the main contaminants of the superficial waters the elements, aluminium (Al), manganese (Mn), zinc (Zn), iron (Fe), sulfates(SO{sub 4}{sup +2}), fluorides(F-), rare earth metals besides uranium (U) and thorium (Th). The Caldas unity is being used as research and testing field for the treatment of areas with environment degradation formed by the mining activity. The ozone testing showed a high efficiency for the removal of iron(Fe), manganese(Mn) and cerium (Ce) up to 99%. The manganese total concentration was reduced to values bellow the ones determined by CONAMA resolution. Elements as neodymium (Nd), zinc (Zn) and lanthanium (La) are also oxidated in presence of ozone but with lower efficiency. The aluminium remained unaffected by the ozone while Thorium and Uranium show an initial decay but at the end present only a concentration slight lower than the initial. The solid material formed after the ozone treatment consists mainly of manganese oxide (85%). In order to dispose, after the ozonization, the liquid effluent to the environment is necessary a pH correction in order to be within the CONAMA legislation, being used less reagent (CaOH{sub 2}), 50 to 86% less, than the amounts used in the process adopted by INB.

    Full Text Available The fight against severe acute malnutrition – which, according to UNICEF, kills between 3.5 and 5 million children under five every year in developing countries – has been a priority for international NGOs and for various United Nations agencies for several decades now. While addressing this ongoing emergency, it is also vital to provide specific nutritional products for the millions of people suffering from moderate to acute malnutrition, and to devise nutritional supplements that are easily affordable for very low-income population groups in Africa, Asia and Latin America. Until recently, all such interventions were left to trial and error in the field; but now they have been made possible thanks to the technological breakthroughs of a French company. Nutriset – founded 25 years ago – is now a leading actor in the humanitarian sector. Its industrial applications and research, in collaboration with the scientific and humanitarian communities, have brought about a genuine revolution in all three areas. By developing a complete range of ready-to-use products, distributed by NGOs, and which the children themselves can use without risk, and by building a global network of local producers, Nutriset has revolutionized the world of nutrition.Le combat contre la malnutrition aiguë sévère qui, d’après l’UNICEF, tue entre 3,5 et 5 millions d’enfants de moins de cinq ans chaque année dans les pays en développement, est depuis plusieurs dizaines d’années l’une des priorités des ONG internationales et de plusieurs agences des Nations Unies. Dans cette situation d’urgence permanente, il est vital de fournir des produits nutritionnels spécifiques aux millions de personnes souffrant de malnutrition modérée à aiguë, et de mettre au point des suppléments nutritionnels abordables pour les populations à très faible revenu en Afrique, en Asie et en Amérique Latine.

    The studied area is represented by the uraniferous district of Lagoa Real, located in the center-south of Bahia State, Brazil. The region is set in a semiarid climate context, with hot and dry weather parameters, with hydric deficit along all months of the year and high aridity index. Rural population is affected on drought periods since small agriculture and animal rearing are the main economic activities which are vulnerable in dry seasons. Groundwater represents the main supply source considering that most surface water sources are temporary and only exhibit flow in rainy periods. The main aquifer system present on the region is fractured, and the presence of groundwater flow occurs through the discontinuities of the rock considering that the rock mass corresponds to the set formed by the rock matrix and all its discontinuities (fractures, foliations, discordance, etc). In this sense, the main purpose of this Master Dissertation was to develop a conceptual model for the aquifer system, through the geotechnical characterization of discontinuities, once these structures allow the secondary porosity of the medium. Hydrochemical data hand out as complement for physical characterization for the behavioral interpretation of the aquifer. The aquifer system is unconfined, however, presents points of stagnation of flow forming compartments without communication with the surrounding areas. According to the International Society of Rock Mechanics ISRM method, which consist on qualitative and quantitative characterization of discontinuities of rock mass scanlines were constructed, systematically, describing, the following structure parameters: attitude, spacing, persistence, openness, infilling and roughness. From the results analysis it could be concluded that the aquifer system is composed of three discontinuities sets: one set which dips to NE, second set dipping to SW-W-NW and the last set sub-horizontal. The first and second sets are responsible for the aquifer recharge. The third set of discontinuities is related of the fractured aquifer communicability and interconnection. The upper part of the rock mass is highly fragmented, however, as depth increases, more penetrative structures and larger spacing between discontinuities prevails, mainly represented by the NE set. These anisotropies are important for deeper areas recharge, and the existence of water flow. Sub horizontal structures persist up to 150 m depth, ensuring the system communicability throughout the analyzed rock mass. Based on the physical-chemical parameters analyses, such as: pH, alkalinity, conductivity, hardness, Na, K, Mg, Ca, Ba, Mn, Fe, Al, SiO{sub 2}, SO{sub 4}{sup 2-}, F{sup -}, Cl{sup -}, NO{sub 3}, ammoniacal N, and NO{sub 2} (all in mg/L), as well as natural U, {sup 226}Ra, {sup 2}'2'8Ra, natural Th and {sup 2}'1'0Pb (in Bq/L), it was possible to establish an aquifer hydrochemical diagnosis, by statistical analysis, background determination and correlations with regional structures, with the intention to assist the understanding of the aquifer system. Results showed that discontinuity distribution were not a predominant factor to the concentrations homogenization of the chemical parameters. In this case, the composition of the rock was revealed as the most important factor. Still semiarid climate influenced on the total dissolved salt content increment, especially when referred to the chloride due to long dry periods, on which usually the region is submitted. Total dissolved salt content was present on high concentrations, before the beginnings of mining activity. The same occurs with uranium radionuclides. Besides having a high background and considering the anomalous nature of the region, some wells presented high radioactive values. However these high levels were linked to the nature of the rock where the well was installed once there was no connection evidence in between these anomalous wells and there were no connection indicators in between surrounding wells whose values were found within the background. Furthermore, it was identified high nitrate levels in the region evidencing anthropogenic pollution intrinsically connected, to animal waste and untreated sewage release. (author)

    Thorium (Th) and Uranium (U) are distributed throughout the earth's crust. The mean thorium concentration ranges from 6 to 15 ppm, which makes it 3 times more abundant than uranium. These radionuclides in their natural form, and in low amounts, do not present a risk to the population because they have low activity, but the effects caused by the accumulation in living beings have not yet been fully elucidated. This work aims to evaluate the concentration of Th and U in the soils of an excerpt in the Atlantic Forest in the State of Pernambuco. Soil sampling (depth 0-20 cm) occurred in the projection of tree crowns of the predominant species in the studied areas. After drying and comminution, samples of 0.1 g of soil were submitted to chemical treatment to enable the analysis. This treatment consisted in the addition of 9 ml of HNO{sub 3} (nitric acid) and 3 ml of HF (hydrofluoric acid) with subsequent heating of the sample and reference materials in a digester oven. The concentrations of Th and U were quantified by Inductively Coupled Plasma Mass Spectrometry - ICP-MS. The mean concentrations found were: 10.5 mg kg{sup -1} for thorium and 2.18 mg.kg{sup -1} for uranium, with values of 35 mg.kg{sup -1} and 26 mg.kg{sup -1} quantified in a thorium sample and uranium respectively. In this region, uranium and thorium hotspot were found, which reinforces the need for greater attention to these radionuclides in the Atlantic Forest of the State of Pernambuco.

    Full Text Available According to Nabokov, the writer’s one and only passport is his style, which allows him to cross and especially transcend any geopolitical boundary. For all that, strangers and foreigners are frequently present in his work. One may even say they haunt every one of his novels and stories, especially Pnin, in which the eponymous hero most vibrantly embodies that concept coined by the Russian Formalists, ostranenie, “making strange”. The present article will explore the essential strangeness which at once constitutes the external shell of the character and informs his deepest inner self, like the “shadow behind the heart” of Pnin that appears in X-rays yet evades all medical explanation. So how does Nabokov succeed in making the reader sense the foreigner’s condition without depriving it of its edge, its aura of strangeness? How can he make us grasp what must usually evade definition? How does his writing achieve this double-bind, making us experience foreignness from the inside as well as the outside?

    Full Text Available Elephantgrass shows a high stocking rate only during the rainy season. Forage production is drastically reduced in the dry season. One of the alternatives to minimize this problem is the supplementation with sugarcane plus urea. In this trial the main goal was to estimate the dry matter intake (DMI of elephantgrass, chopped sugarcane plus 1% urea and their degradability in three lactating (11.6kg/milk/day rumen fistulated crossbred cows (472kg/L.W. grazing elephantgrass during the dry season. The cows had access during three consecutive night to the paddocks grazed every 30 days in a stocking rate, of 4.5 cows/hectare. Between the two milking times, cows received chopped sugarcane plus 1% urea. The DMI was on average 1.01%/L.W. for the elephantgrass and 0.88%/L.W. for the sugarcane plus 1% urea. Total DMI, taking into account both roughage and concentrate (2kg/cow/day was 2.25%/L.W. The effective rumen degradability (ED, considering the rate of passage in the rumen of 5%/hour was 44.46% for elephantgrass and 41.94% for sugarcane plus 1% urea, DM. The elephantgrass ED crude protein was 48.58% and its neutral detergent fiber 33.82%. During the dry season lactating crossbred cows grazing elephantgrass have to receive a roughage supplement and concentrate to produce around to 12kg of milk per day.

    2000-03-31

    Uterine rupture (UR), a potentially life-threatening condition for both mother and infant, occurs in vaginal birth after cesarean section (VBAC) (1-4). During 1990-1997, the proportion of vaginal deliveries among women who had previous cesarean sections (CS) in Massachusetts increased 50%, from 22.3% to 33.5% (5). Concern about a corresponding increase in UR prompted the Massachusetts Department of Public Health and CDC to initiate a state-wide investigation that included an assessment of the validity and reliability of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) (6), codes in hospital discharge data to identify UR cases. This report summarizes the results of the investigation, which indicate that ICD-9-CM codes related to UR, designed before increased concern about UR, lack adequate specificity for UR surveillance and have not been applied consistently over time.

    Uncaria rhynchophylla (UR), which is a traditional Chinese medicine, has anticonvulsive effect in our previous studies, and the cellular mechanisms behind this are still little known. Because of this, we wanted to determine the importance of the role of UR on kainic acid- (KA-) induced epilepsy. Oral UR for 6 weeks can successfully attenuate the onset of epileptic seizure in animal tests. Hippocampal mossy fiber sprouting dramatically decreased, while neuronal survival increased with UR treatment in hippocampal CA1 and CA3 areas. Furthermore, oral UR for 6 weeks significantly attenuated the overexpression of astrocyte proliferation and S100B proteins but not γ-aminobutyric acid A (GABA(A)) receptors. These results indicate that oral UR for 6 weeks can successfully attenuate mossy fiber sprouting, astrocyte proliferation, and S100B protein overexpression and increase neuronal survival in KA-induced epileptic rat hippocampus.

    This study sought to evaluate factors associated with unplanned hospital return (UR) following transurethral resection of bladder tumor (TURBT), the largest source of readmission among ambulatory urological procedures. A retrospective review of TURBTs at a single academic institution between April 2011 and August 2014 was performed. Demographics, comorbidities, length of stay, tumor size and multiple other factors were recorded. UR was recorded within 30 days of surgery. Bivariate and multivariable analyses were performed to determine factors associated with UR. Among 708 patients undergoing TURBT, 23.9% were female with a mean age of 70 years. The rate of UR was 10.9%. The most common cause of UR was gross hematuria, accounting for 70%. On bivariate analysis, Foley catheter placement in the operating room, non-aspirin anticoagulation and index length of stay longer than 24 h were associated with hematuria-related UR (p hematuria-related UR (p  0.05). On multivariable analysis, only Foley placement in the operating room remained associated with higher rates of hematuria-related UR, while preoperative antibiotics, female gender and aspirin therapy remained associated with a lower likelihood of this event. UR following TURBT is common and typically results from gross hematuria. Patients with postoperative Foley catheterization in the operating room may require additional counseling or supervision before discharge, and should be considered for discharge with a Foley rather than having a prompt voiding trial.

  1. Analysis of the Umbrella Roof for lifting

    Shaaban, A.

    1983-01-01

    In addition to supporting the dead loads and the operational loads, the Umbrella Roof (UR) has two major functions to which it was designed. First is to allow access for repair and removal of any of the TF coils, the upper PF coils and the Vacuum Vessel sections; and second, is to reproduce the exact positioning of the upper PF coils every time the UR is placed over the Tokamac. To provide these functions, the UR is designed to be lifted as one integrated structure to which the upper PF coils are attached. In order to ensure precise positioning of the UR, a redundant system of 13 guide pins were provided on the bottom of the radial beams, and four shear lugs were provided atop the central column. Mating reciprocals with very close tolerance for the guide pins were provided in the tops of the 13 peripheral columns. To meet close tolerances and to accommodate such high redundancy in match points, accurate analysis was necessary by which the center of gravity of the UR can be located and the deflection of all match points can be computed. Also stress analysis of the members of the UR was necessary because when the UR is lifted it is denied the midpoint support over the center column; and also the beams of the UR are not interconnected by moment-capable joints, thus if provisions are not made to support every radial beam, those which are not supported would yield and collapse. In this paper, the lifting schemes proposed for the UR are discussed and the results of the analysis performed for the elected scheme are presented. Also presented is a unique application of the NASTRAN code by which the center of gravity of the UR was located by allowing a refined model of the UR to swing until it came to rest under an arbitrary lift point

    Full Text Available An administrative contract is the will between a public authority either a person empowe¬red by it, and one or more natural or legal persons, whether private or public, pursuing the realization of a public interest and to which a special scheme of administrative law applies. The typology of administrative contracts is very varied, depending on the evolution of the society’s needs. Thus, they are currently included in the category of administrative contracts: concession contracts and public procurement contracts, contracts for the use of public goods, public management contracts, public-private partnership contracts, public lending contracts and constitutive documents of the associative structures of public authorities.

    Full Text Available Time- and vehicle-related variability of bladder and urethral rhabdosphincter (URS activity as well as cardiorespiratory and blood chemistry values were examined in the acetic acid-induced bladder irritation model in α-chloralose-anesthetized female cats. Additionally, bladder and urethra were evaluated histologically using Mason trichrome and toluidine blue staining. Urodynamic, cardiovascular and respiratory parameters were collected during intravesical saline infusion followed by acetic acid (0.5% to irritate the bladder. One hour after starting acetic acid infusion, a protocol consisting of a cystometrogram, continuous infusion-induced rhythmic voiding contractions, and a 5 min "quiet period" (bladder emptied without infusion was precisely repeated every 30 minutes. Administration of vehicle (saline i.v. occurred 15 minutes after starting each of the first 7 cystometrograms and duloxetine (1mg/kg i.v. after the 8(th. Acetic acid infusion into the bladder increased URS-EMG activity, bladder contraction frequency, and decreased contraction amplitude and capacity, compared to saline. Bladder activity and URS activity stabilized within 1 and 2 hours, respectively. Duloxetine administration significantly decreased bladder contraction frequency and increased URS-EMG activity to levels similar to previous reports. Cardiorespiratory parameters and blood gas levels remained consistent throughout the experiment. The epithelium of the bladder and urethra were greatly damaged and edema and infiltration of neutrophils in the lamina propria of urethra were observed. These data provide an ample evaluation of the health of the animals, stability of voiding function and appropriateness of the model for testing drugs designed to evaluate lower urinary tract as well as cardiovascular and respiratory systems function.

    2015-11-01

    Full Text Available The activity of administrative bodies includes big numbers of various acts and actions, through which the will of public administration is formed. The will of public administration bodies, expressed in administrative individual and normative acts, in administrative contracts and real acts, finds its reflection in the Constitution, laws and other provisions of legal character. All this activity is not inerrant and therefore, it is not uncontrollable. The supervision of executive activity is subject to political control of administrative acts through authorities designated for this purpose, as well as internal control and the judicial control. The institution of judicial control of administrative acts and actions appears as very important and widely treated in the legal doctrine. The protection of constitutional and legal rights of private persons is accomplished by subjecting administrative activity both to internal administrative control, as well as to the judicial control in accordance with legal provisions. The judicial control of administrative acts represents a constitutional guarantee for citizens to protect their rights through public and fair trial by an independent and impartial court. In this way, the Constitution empowers the common administrative court that invalidates an action or administrative act, but not all administrative acts may be subject to administrative dispute, with the exception of cases against which the administrative conflict cannot be carried out (negative enumeration.

    Full Text Available The purpose of this study was to evaluate the effects of Ulva rigida C. Agardh, one of the green algae, on and antioxidative system in the propylthiouracil (PTU-induced hypothyroid rats. Thirty-two rats randomly divided into four groups: control (C, control+U. rigida extract (C+UR, hypothyroid (H and hypothyroid+U. rigida extract (H+UR. U. rigida (2% was administered in drinking water for 5 weeks after the induction of hypothyroidism. Hypothyroid rats were under oxidative stress as reflected by icreased plasma and tissue malondialdehyde (MDA levels. U. rigida reduced serum total cholesterol and,- triglyceride levels and plasma and heart skeletal muscle, liver and,- kidney tissue MDA levels in the H+UR group. Serum total cholesterol and tissues MDA levels were reduced in the C+UR group. Whole blood glutathione peroxidase and erythrocyte superoxide dismutase activities were increased in the H+UR and C+UR groups compared with those of te respective control groups. Paraoxonase and arylesterase activities were lower in the H group and U. rigida increased paraoxonase and arylesterase activities in C+UR and H+UR groups. We conclude that hypothyroidism is associated with oxidative stress and, U. rigida extract might have a potential use as a protective antioxidant agent in hypothroidism.

    A generalized evaluation of the impacts associated with different urban stormwater runoff (UR) treatment techniques is presented. It addresses the definition of the problem, estimates the volume and characteristics of the UR and the sludges expected, evaluates six methods of UR sludge treatment, and examines alternatives and impacts for UR treatment sludge handling such as bleed/pump back to the dry weather plant, and land disposal. Regarding bleed/pump back of UR sludges, solids deposition in sewers and overload to the dry weather facilities are anticipated to cause problems. The most cost effective sludge treatment alternative appeared to be lime stabilization followed by thickening, pressure filter dewatering, and landfill disposal. Secondary impacts included costs, water quality, noise, energy consumption, air pollution, and land area requirements

    Full Text Available The study investigated self-efficacy of a sample of Slovak primary schoolteachers in two areas: area of instruction and area of parent involvement. Twoinstruments were used: the 16-item Slovak version of Teacher Efficacy Scale ofGibson and Dembo, and ZdUR, a 24-item scale to measure self-efficacy of teacherin parents’ involvement, developed by authors of the present study. The correlation between scores of personal teaching efficacy dimension of TES and ZdUR was 0.58 and between general teaching efficacy of TES and ZdUR was only 0.01. Teachers inthis sample had better scores in all dimensions of ZdUR than those of TES, with theexception of engaging parents in school activities. Scores of four teachers in TES andZdUR were analysed to document the possibility of making the individual profiles ofteacher self-efficacy.

  9. Reversible transition between bipolar and unipolar resistive switching in Cu2O/Ga2O3 binary oxide stacked layer

    Full Text Available Both unipolar resistive switching (URS and bipolar resistive switching (BRS behaviors are observed in Cu2O/Ga2O3 stacked layer. The conversion between BRS and URS is controllable and reversible. The switching operations in BRS mode requires smaller voltage than that in the URS mode. The oxygen vacancies closed to the Cu2O/Ga2O3 interface contributes to the BRS, and the bias-controlling filament formation/rupture in depletion layer is considered to contribute to the URS. The URS happens only in the negative voltage part due to the nature of directionality of the p-n junction. The process reported here can be developed to design memory device.

    Full Text Available Epileptic seizures are crucial clinical manifestations of recurrent neuronal discharges in the brain. An imbalance between the excitatory and inhibitory neuronal discharges causes brain damage and cell loss. Herbal medicines offer alternative treatment options for epilepsy because of their low cost and few side effects. We established a rat epilepsy model by injecting kainic acid (KA, 12 mg/kg, i.p. and subsequently investigated the effect of Uncaria rhynchophylla (UR and its underlying mechanisms. Electroencephalogram and epileptic behaviors revealed that the KA injection induced epileptic seizures. Following KA injection, S100B levels increased in the hippocampus. This phenomenon was attenuated by the oral administration of UR and valproic acid (VA, 250 mg/kg. Both drugs significantly reversed receptor potentiation for advanced glycation end product proteins. Rats with KA-induced epilepsy exhibited no increase in the expression of metabotropic glutamate receptor 3, monocyte chemoattractant protein 1, and chemokine receptor type 2, which play a role in inflammation. Our results provide novel and detailed mechanisms, explaining the role of UR in KA-induced epileptic seizures in hippocampal CA1 neurons.

    Full Text Available OBJECTIVE: We compared the efficacy of extracorporeal shock wave lithotripsy (ESWL and ureteroscopy (URS for the treatment of distal ureteral calculi with respect to patient satisfaction. MATERIALS AND MHETODS: This is a prospective study where a total of 212 patients with solitary, radiopaque distal ureteral calculi were treated with ESWL (n = 92 using Dornier lithotriptor S (MedTech Europe GmbH or URS (n = 120. Patient and stone characteristics, treatment parameters, clinical outcomes, and patient satisfaction were assessed for each group. RESULTS: The 2 groups were comparable in regard to patient age, sex, stone size, and side of treatment. The stone-free status for ESWL and URS at 3 months was 81.5% and 97.5%, respectively (p < 0.0001. In addition, 88% of patients who underwent ESWL versus 20% who underwent URS were discharged home the day of procedure. Minor complications occurred in 3.3% and 8.3% of the ESWL and URS groups, respectively (p = 0.127. No ureteral perforation or stricture occurred in the URS group. Postoperative flank pain and dysuria were more severe in the URS than ESWL group, although the differences were not statistically significant (p = 0.16. Patient satisfaction was high for both groups, including 94% for URS and 80% for ESWL (p = 0.002. CONCLUSIONS: URS is more effective than ESWL for the treatment of distal ureteral calculi. ESWL was more often performed on an outpatient basis, and showed a trend towards less flank pain and dysuria, fewer complications and quicker convalescence. Patient satisfaction was significantly higher for URS according to the questionnaire used in this study.
