    The Pillard company has developed, in cooperation with GDF (the French national gas utility), the GR-LONOxFLAM burner concept for reducing NOx emission levels and solid combustion products. The concept consists, for gaseous fuels, in the combination of an internal recirculation and a gas staging process; for liquid fuels, a separated flame process and air staging are combined. These concepts allow for an important reduction in NOx and non-burned residues, even with standard-size burners

    This paper presents the research work carried out by the French Pillard company in collaboration with Gaz de France for the design of low NO{sub x} burners. The different type of low NO{sub x} burners are presented according to the type of fuel: gas, liquid fuels and fuel oils. The gas burner uses the fuel staging principle and the recirculation of smokes and leads to NO{sub x} emissions lower than 100 mg/Nm{sup 3}. The liquid fuel and fuel oil burners use the separate flames and the smoke self-recirculation methods (fuel-air mixture staging, reduction of flame temperature and of the residence time in flames).

    Systemteorien drejer sig basalt om grænser. Den kommunikerer om grænser mellem system og omverden, grænser mellem funktionssystemer, der eventuelt kan kobles sammen ved hjælp af nye grænsesættelser, grænser som distinktioner mellem koder, og endda grænser for hvad der kan kommunikeres om. Niklas...... Luhmann formulerer mange af disse grænser som tidslige grænser mellem før og efter, fortid og nutid. På den baggrund kan hans teori om sociale kommunikationssystemer synes abstrakt, endog verdensfjern. Men han anvender også sin teoridannelse netop i den tidslige historiske tilrettelæggelse af rumlige...

    The human glucocorticoid receptor (GR) gene produces C-terminal GR{beta} and GR{alpha} isoforms through alternative use of specific exons 9{beta} and {alpha}, respectively. We explored the transcriptional activity of GR{beta} on endogenous genes by developing HeLa cells stably expressing EGFP-GR{beta} or EGFP. Microarray analyses revealed that GR{beta} had intrinsic gene-specific transcriptional activity, regulating mRNA expression of a large number of genes negatively or positively. Majority of GR{beta}-responsive genes was distinct from those modulated by GR{alpha}, while GR{beta} and GR{alpha} mutually modulated each other's transcriptional activity in a subpopulation of genes. We did not observe in HCT116 cells nuclear translocation of GR{beta} and activation of this receptor by RU 486, a synthetic steroid previously reported to bind GR{beta} and to induce nuclear translocation. Our results indicate that GR{beta} has intrinsic, GR{alpha}-independent, gene-specific transcriptional activity, in addition to its previously reported dominant negative effect on GR{alpha}-induced transactivation of GRE-driven promoters.

  17. Gröbner bases statistics and software systems

    CERN Document Server

    2013-01-01

    The idea of the Gröbner basis first appeared in a 1927 paper by F. S. Macaulay, who succeeded in creating a combinatorial characterization of the Hilbert functions of homogeneous ideals of the polynomial ring. Later, the modern definition of the Gröbner basis was independently introduced by Heisuke Hironaka in 1964 and Bruno Buchberger in 1965. However, after the discovery of the notion of the Gröbner basis by Hironaka and Buchberger, it was not actively pursued for 20 years. A breakthrough was made in the mid-1980s by David Bayer and Michael Stillman, who created the Macaulay computer algebra system with the help of the Gröbner basis. Since then, rapid development on the Gröbner basis has been achieved by many researchers, including Bernd Sturmfels. This book serves as a standard bible of the Gröbner basis, for which the harmony of theory, application, and computation are indispensable. It provides all the fundamentals for graduate students to learn the ABC’s of the Gröbner basis, requiring no speci...

    BACKGROUND: Previous studies have compared sperm phenotypes between men with partial deletions within the AZFc region of the Y chromosome and non-carriers, with variable results. In this study, a separate question was investigated, the basis of the variation in sperm phenotype within gr/gr deletion...... carriers, which ranges from normozoospermia to azoospermia. Differences in the genes removed by independent gr/gr deletions, the occurrence of subsequent duplications or the presence of linked modifying variants elsewhere on the chromosome have been suggested as possible causal factors. This study set out...... to test these possibilities in a large sample of gr/gr deletion carriers with known phenotypes spanning the complete range. RESULTS: In total, 169 men diagnosed with gr/gr deletions from six centres in Europe and one in Australia were studied. The DAZ and CDY1 copies retained, the presence or absence...

  7. Modeling Gravitational Waves to Test GR Dispersion and Polarization

    Given continued observation runs from the Laser Interferometer Gravitational-Wave Observatory Scientific Collaboration, further gravitational wave (GW) events will provide added constraints on beyond-general relativity (b-GR) theories. One approach, independent of the GW generation mechanism at the source, is to look at modification to the GW dispersion and propagation, which can accumulate over vast distances. Generic modification of GW propagation can also, in certain b-GR theories, impact the polarization content of GWs. To this end, a comprehensive approach to testing the dispersion and polarization content is developed by modeling anisotropic deformations to the waveforms' phase, along with birefringence effects and corollary consequences for b-GR polarizations, i.e., breathing, vector, and longitudinal modes. Such an approach can be mapped to specific theories like Lorentz violation, amplitude birefringence in Chern-Simons, and provide hints at additional theories to be included. An overview of data analysis routines to be implemented will also be discussed.

  8. mKikGR, a monomeric photoswitchable fluorescent protein.

    Directory of Open Access Journals (Sweden)

    Satoshi Habuchi

    Full Text Available The recent demonstration and utilization of fluorescent proteins whose fluorescence can be switched on and off has greatly expanded the toolkit of molecular and cell biology. These photoswitchable proteins have facilitated the characterization of specifically tagged molecular species in the cell and have enabled fluorescence imaging of intracellular structures with a resolution far below the classical diffraction limit of light. Applications are limited, however, by the fast photobleaching, slow photoswitching, and oligomerization typical for photoswitchable proteins currently available. Here, we report the molecular cloning and spectroscopic characterization of mKikGR, a monomeric version of the previously reported KikGR that displays high photostability and switching rates. Furthermore, we present single-molecule imaging experiments that demonstrate that individual mKikGR proteins can be localized with a precision of better than 10 nanometers, suggesting their suitability for super-resolution imaging.

Sin embargo, se han presentado propuestas orientadas a mejorar el desempeño de los mismos, principalmente en los aspectos referentes a la incertidumbre y ambigüedad existente en los datos. En este sentido, los gráficos de control difusos son una alternativa valiosa para mejorar el desempeño de los gráficos tradicionales. Se presenta, entonces, una comparación de los gráficos de control Shewhart (tradicionales y los gráficos de control difusos por atributos, con el objetivo de establecer las similitudes y diferencias existentes entre las dos metodologías. De esta manera, se desarrolla un ejemplo numérico de un gráfico tradicional c y gráficos difusos construidos a partir de las siguientes técnicas de transformación: moda difusa, mediana difusa, rango medio difuso y enfoque difuso directo. Para realizar una comparación se utilizaron las reglas de evaluación de patrones de comportamiento no natural en un gráfico de control. A partir de los resultados de la comparación realizada en esta investigación se concluye que al utilizar las reglas de evaluación en ambos gráficos con los mismos datos no se obtienen diferencias en los resultados.

    In vivo bioluminescence imaging is a persuasive approach to investigate a number of issues in microbial pathogenesis. Previously, we have applied bioluminescence imaging to gain greater insight into Brucella melitensis pathogenesis. Endowing Brucella with bioluminescence allowed direct visualization of bacterial dissemination, pattern of tissue localization, and the contribution of Brucella genes to virulence. In this report, we describe the pathogenicity of three attenuated bioluminescent B. melitensis mutants, GR019 (virB4), GR024 (galE), and GR026 (BMEI1090-BMEI1091), and the dynamics of bioluminescent virulent bacterial infection following vaccination with these mutants. The virB4, galE, and BMEI1090-BMEI1091 mutants were attenuated in interferon regulatory factor 1-deficient (IRF-1(-/-)) mice; however, only the GR019 (virB4) mutant was attenuated in cultured macrophages. Therefore, in vivo imaging provides a comprehensive approach to identify virulence genes that are relevant to in vivo pathogenesis. Our results provide greater insights into the role of galE in virulence and also suggest that BMEI1090 and downstream genes constitute a novel set of genes involved in Brucella virulence. Survival of the vaccine strain in the host for a critical period is important for effective Brucella vaccines. The galE mutant induced no changes in liver and spleen but localized chronically in the tail and protected IRF-1(-/-) and wild-type mice from virulent challenge, implying that this mutant may serve as a potential vaccine candidate in future studies and that the direct visualization of Brucella may provide insight into selection of improved vaccine candidates.

  15. CRTC2 Is a Coactivator of GR and Couples GR and CREB in the Regulation of Hepatic Gluconeogenesis.

    Glucocorticoid hormones play essential roles in the regulation of gluconeogenesis in the liver, an adaptive response that is required for the maintenance of circulating glucose levels during fasting. Glucocorticoids do this by cooperating with glucagon, which is secreted from pancreatic islets to activate the cAMP-signaling pathway in hepatocytes. The cAMP-response element-binding protein (CREB)-regulated transcription coactivator 2 (CRTC2) is a coactivator known to be specific to CREB and plays a central role in the glucagon-mediated activation of gluconeogenesis in the early phase of fasting. We show here that CRTC2 also functions as a coactivator for the glucocorticoid receptor (GR). CRTC2 strongly enhances GR-induced transcriptional activity of glucocorticoid-responsive genes. CRTC2 physically interacts with the ligand-binding domain of the GR through a region spanning amino acids 561-693. Further, CRTC2 is required for the glucocorticoid-associated cooperative mRNA expression of the glucose-6-phosphatase, a rate-limiting enzyme for hepatic gluconeogenesis, by facilitating the attraction of GR and itself to its promoter region already occupied by CREB. CRTC2 is required for the maintenance of blood glucose levels during fasting in mice by enhancing the GR transcriptional activity on both the G6p and phosphoenolpyruvate carboxykinase (Pepck) genes. Finally, CRTC2 modulates the transcriptional activity of the progesterone receptor, indicating that it may influence the transcriptional activity of other steroid/nuclear receptors. Taken together, these results reveal that CRTC2 plays an essential role in the regulation of hepatic gluconeogenesis through coordinated regulation of the glucocorticoid/GR- and glucagon/CREB-signaling pathways on the key genes G6P and PEPCK.

Na terenie Polski, w miarę rozprzestrzeniania się przychodzącego z Europy postępu technicznego, styl Grűnderzeit następował pod koniec XIX wieku z niewielkim tylko opóźnieniem w stosunku do Niemiec, a wraz z nim jeszcze 12 stylów okresu historyzmu. Budynki z okresu Grűnderzeit, powszechnie obecne w centrach polskich miast pomimo zniszczeń spowodowanych II wojną, stanowią zwykle obiekty najstarsze i choćby z tego powodu uznawane są za estetyczny kanon historycznej zabudowy mieszkaniowej. Zamiarem autora jest przywrócenie do literatury polskiej terminu Grűnderzeit jako bardziej precyzyjnie określającego styl niż termin ‘historyzm’, używany do opisania praktycznie każdej formy architektonicznej z okresu poprzedzającego modernizm. Autorowi chodzi też o spowodowanie w polskiej literaturze dekonstrukcji terminu ‘historyzm’ i wyodrębnienie z niego terminu Grűnderzeit, ponadto o rozprawienie się z funkcjonującymi na temat stylu Grűnderzeit uprzedzeniami oraz o wykazanie związków i wpływu tego stylu na architekturę tkanki miejskiej większości polskich miast, nie tylko tych położonych na zachód od Wisły.

    IR- and Raman-active phonons of boron carbide and the mode Grüneisen parameters γ related are studied concerning their dependence on chemical composition, temperatures between 30 and 800 K and pressures up to ∼70 GPa. Most bulk phonons yield γ between +1.5 and - 1.5: those related to icosahedra yield γ = 0.8(3). Surface phonons are distinguished by considerably higher γ. Negative γ of chain bending modes supports the assumption that the chain center buckles out under pressure. Some striking specific mode Grüneisen parameters are explained. Pressure-dependent bond lengths suggest the reversible high-pressure phase transition to be second order.

    Strigolactones have recently been implicated in both above- and below-ground developmental pathways in higher plants. To facilitate the molecular and chemical properties of strigolactones in vitro and in vivo, we have developed a fluorescent strigolactone molecule, CISA-1, synthesized via a novel method which was robust, high-yielding, and used simple starting materials. We demonstrate that CISA-1 has a broad range of known strigolactone activities and further report on an adventitious rooting assay in Arabidopsis which is a highly sensitive and rapid method for testing biological activity of strigolactone analogs. In this rooting assay and the widely used Orobanche germination assay, CISA-1 showed stronger biological activity than the commonly tested GR24. CISA-1 and GR24 were equally effective at inhibiting branching in Arabidopsis inflorescence stems. In both the branching and adventitious rooting assay, we also demonstrated that CISA-1 activity is dependent on the max strigolactone signaling pathway. In water methanol solutions, CISA-1 was about threefold more stable than GR24, which may contribute to the increased activity observed in the various biological tests.

    The mechanical properties and irradiation embrittlement behavior of SA508 Gr.4N low alloy steel were evaluated. The yield strength and tensile strength were increased with an increase in fluence level, but there is no drastic increase in strength. A significant increase in the transition temperature shifts from the Charpy impact test and fracture toughness test was not observed in SA508 Gr.4N model alloy. The overall irradiation embrittlement behavior of SA508 Gr.4N low alloy steel is almost similar to that of SA508 Gr.3 low alloy steel, and an increase in Ni content by a few percentage points in SA508 Gr.4N model alloys compared to SA508 Gr.3 low alloy steel did not result in an increased embrittlement of these alloys. The yield strength was increased with an increase in the neutron fluence level, and the amount of strength increase was comparable to commercial SA508 Gr.3 low alloy steel.

  17. P53 and p73 differ in their ability to inhibit glucocorticoid receptor (GR transcriptional activity

    Directory of Open Access Journals (Sweden)

    Nie Linghu

    2006-12-01

    Full Text Available Abstract Background p53 is a tumor suppressor and potent inhibitor of cell growth. P73 is highly similar to p53 at both the amino acid sequence and structural levels. Given their similarities, it is important to determine whether p53 and p73 function in similar or distinct pathways. There is abundant evidence for negative cross-talk between glucocorticoid receptor (GR and p53. Neither physical nor functional interactions between GR and p73 have been reported. In this study, we examined the ability of p53 and p73 to interact with and inhibit GR transcriptional activity. Results We show that both p53 and p73 can bind GR, and that p53 and p73-mediated transcriptional activity is inhibited by GR co-expression. Wild-type p53 efficiently inhibited GR transcriptional activity in cells expressing both proteins. Surprisingly, however, p73 was either unable to efficiently inhibit GR, or increased GR activity slightly. To examine the basis for this difference, a series of p53:p73 chimeric proteins were generated in which corresponding regions of either protein have been swapped. Replacing N- and C-terminal sequences in p53 with the corresponding sequences from p73 prevented it from inhibiting GR. In contrast, replacing p73 N- and C-terminal sequences with the corresponding sequences from p53 allowed it to efficiently inhibit GR. Differences in GR inhibition were not related to differences in transcriptional activity of the p53:p73 chimeras or their ability to bind GR. Conclusion Our results indicate that both N- and C-terminal regions of p53 and p73 contribute to their regulation of GR. The differential ability of p53 and p73 to inhibit GR is due, in part, to differences in their N-terminal and C-terminal sequences.

    In this study, microstructure and mechanical properties of SA508 Gr.3 Cl. 1, Cl.2, and Gr.4N low alloy steels are characterized to compare their properties. To evaluate the fracture toughness in the transition region, the master curve method according to ASTM E1921 was adopted in the cleavage transition region. Tensile tests and Charpy impact tests were also performed to evaluate the mechanical properties, and a microstructural investigation was carried out. The microstructure and mechanical properties of SA508 Gr.3 Cl.1, Cl2 and Gr.4N low alloy steels were characterized.. The predominant microstructure of SA508 Gr.4N model alloy is tempered martensite, while SA508 Gr.3 Cl.1 and Cl.2 steels show a typical tempered upper bainitic structure. SA508 Gr. 4N model alloy shows the best strength and transition behavior among the three SA508 steels. SA508 Gr.3 Cl.2 steel also has quite good strength, but there is a loss of toughness.

    The basic building blocks of the Cosmic Web are groups and clusters of galaxies, super-clusters (pancakes) and filaments embedded in the universal dark energy background. The background produces antigravity, and the antigravity effect is strong in groups, clusters and superclusters. Antigravity is very weak in filaments where matter (dark matter and baryons) produces gravity dominating in the filament internal dynamics. Gravity-antigravity interplay on the large scales is a grandiose phenomenon predicted by ΛGR theory and seen in modern observations of the Cosmic Web.

    Franz Kafkas forfatterskab blev berømt i årene efter Anden Verdenskrig, i skyggen af det korte 20. århundredes totalitarisme og atomtrussel, og i dette intellektuelle klima lå det lige for at fortolke hans litterære værker som en skildring af en skæbneagtig verden som det ikke står i menneskenes...... magt at forandre. Den meget velkendte forestilling om "det kafkaske" rummer en politisk ontologi, et grundlæggende billede af tingenes orden, der trækker en skarp grænse mellem det magtesløse enkeltmenneske og de meningsløse skæbnemagter. I Stormløb mod grænsen forsøger jeg at redde Kafka ud af den...... kolde krigs skygge ved at insistere på at det politiske spiller en afgørende rolle – ikke bare for værkernes indhold, men også for værkernes form.

  3. How secure are Grünbaum's Foundations?

    As exemplified in Freud's cases, behaviour becomes meaningful as it is situated within a history (narrative). Operating from a Unity of Science orientation, Grünbaum emphasises causal rather than meaningful connections, and selectively follows early Freud: when (and only when) the repressed historical cause is uncovered, the symptom disappears. Since that consequential connection has proven to be not causally invariable Grünbaum discredits psychoanalysis as unscientific. Counterposed to his causal approach is that of philosopher MacIntyre, who contends that identity and moral responsibility must be situated within personal history. Also counterposed is sociologist Max Weber who struggled with parallel issues in the German 'Geisteswissenschaften' of Freud's time. The oedipal complex is akin to Weber's ideal types, as are the various models implicit in analytic discourse. Psychoanalysis must be understood as a normative science. In so far as contemporary psychology and psychiatry emphasise causal relationships, their procedures (experimental, epidemiological) can never hope to encompass psychoanalysis. Like other grand theoretical systems, psychoanalysis has applications in wide arenas--personal, developmental, familial, cultural, religious, historical, ethnological; its development during the last century has come from the interaction of findings from those arenas with those from the consulting room.

  4. Interruption with the Migration of Iodide by GR(CT)

    The purpose of this study is to understand the influence of green rust on the migration of iodide. GR(CT) would be major corrosion product of iron near the seawater or saline layer in underground. The GR(CT) may play an important role in the retardation of the iodide migration in a deep geological environment due to it's anionic exchange reaction. In underground radioactive waste repository, the corrosion of iron canisters would be proceed as follows; Fe(II) and/or Fe(III) dissolved from iron containers → Fe(II)(OH) 2 and/or Fe(III)(OH) 3 → Green rust → Lepidocrocite or Magnetite → Goetite etc. Generally, the green rust has known to exist in environments close to the Fe(Π)/Fe(ΠΙ) transition zone or between the oxidized layer and reduced layer in the underground. As anion exchanger and strong reducer, the green rusts can affect the migration of anions, reactions involving green rusts were poorly studied in relation to the safety assessment of radioactive waste repository

    Full Text Available Corticosteroids regulate stress response and influence emotion, learning, and memory via two receptors in the brain, the high‐affinity mineralocorticoid (MR and low‐affinity glucocorticoid receptor (GR. We test the hypothesis that MR- and GR-mediated effects interact in emotion and cognition when a novel situation is encountered that is relevant for a learning process. By adrenalectomy and additional constant corticosterone supplement we obtained four groups of male C57BL/6J mice with differential chronic MR and GR activations. Using a hole board task, we found that mice with continuous predominant MR and moderate GR activations were fast learners that displayed low anxiety and arousal together with high directed explorative behavior. Progressive corticosterone concentrations with predominant action via GR induced strong emotional arousal at the expense of cognitive performance. These findings underline the importance of a balanced MR/GR system for emotional and cognitive functioning that is critical for mental health.

  17. On the Computation of Comprehensive Boolean Gröbner Bases

    Science.gov (United States)

    Inoue, Shutaro

    We show that a comprehensive Boolean Gröbner basis of an ideal I in a Boolean polynomial ring B (bar A,bar X) with main variables bar X and parameters bar A can be obtained by simply computing a usual Boolean Gröbner basis of I regarding both bar X and bar A as variables with a certain block term order such that bar X ≫ bar A. The result together with a fact that a finite Boolean ring is isomorphic to a direct product of the Galois field mathbb{GF}_2 enables us to compute a comprehensive Boolean Gröbner basis by only computing corresponding Gröbner bases in a polynomial ring over mathbb{GF}_2. Our implementation in a computer algebra system Risa/Asir shows that our method is extremely efficient comparing with existing computation algorithms of comprehensive Boolean Gröbner bases.

    With the growth of genome databases and the implied complexity for processing such information within bioinformatics research, there is a need for computing power and massive storage facilities which can be provided by Grid infrastructures. EMBOSS is a free Open Source sequence analysis package specially developed for the needs of the bioinformatics and molecular biology user community. This work describes the deployment of EMBOSS over the EELA and EGEE Grids, both gLite middle ware-based infrastructures. This work is focused on rewriting the I/O EMBOSS libraries (AJAX) to use the GFAL from the LCG/EGEE middle ware. This library allows the use of files registered on the catalog service which are contained in the storage elements of a Grid. Submitting a job into a Grid is not an intuitive task. This work also describes an ad hoc mechanism to allow bioinformaticians to concentrate on the EMBOSS command, instead of acquiring advanced knowledge about Grid usage. The results obtained so far demonstrate the functionality of GrEMBOSS, and represent an efficient and viable alternative for gridifying other bioinformatics applications. (Author)

    Science.gov (United States)

    Taha, Kamal

    2013-12-01

    We introduce in this paper a biological search engine called GRtoGR. Given a set of S genes, GRtoGR would determine from GO graph the most significant Lowest Common Ancestor (LCA) of the GO terms annotating the set S. This significant LCA annotates the genes that are the most semantically related to the set S. The framework of GRtoGR refines the concept of LCA by introducing the concepts of Relevant Lowest Common Ancestor (RLCA) and Semantically Relevant Lowest Common Ancestor (SRLCA). A SRLCA is the most significant LCA of the GO terms annotating the set S. We observe that the existence of the GO terms annotating the set S is dependent on the existence of this SRLCA in GO graph. That is, the terms annotating a given set of genes usually have existence dependency relationships with the SRLCA of these terms. We evaluated GRtoGR experimentally and compared it with nine other methods. Results showed marked improvement.

    Objective: To explore the expression and significance of glucocorticoid receptor (GR) in hypothalamus and pituitary gland of rats after high power microwave (HPM) exposure. Methods: A total of 130 male Wistar rats were sacrificed at 6 h, 1 d, 3 d, 7 d, 14 d, 28 d and 3 m after whole body irradiation by 2-90 mW/cm 2 HPM and their hypothalamus and pituitary gland were collected. The changes of GR in the two tissues after HPM exposure were investigated by means of immunohistochemical staining and image analysis. Results: The expression of GR in hypothalamus was decreased after HPM exposure. The level of GR in the group of 10 mW/cm 2 was significantly lower (P 2 group was significantly lower (P 2 group was significantly higher (P 2 group was significantly higher (P<0.01) on 1 d and 3 d after HPM exposure. Conclusion: The expression of GR in hypothalamus was decreased while that in the anterior pituitary was increased after HPM exposure. The refore, the negative feedback of hypothalamic-pituitary-adrenal (HPA) axis was upset and the changes of GR is involved in the pathophysiological course of HPA. (authors)

  12. Glucocorticoid Signaling in Health and Disease: Insights From Tissue-Specific GR Knockout Mice.

    Science.gov (United States)

    Whirledge, Shannon; DeFranco, Donald B

    2018-01-01

    Glucocorticoids are adrenally produced hormones critically involved in development, general physiology, and control of inflammation. Since their discovery, glucocorticoids have been widely used to treat a variety of inflammatory conditions. However, high doses or prolonged use leads to a number of side effects throughout the body, which preclude their clinical utility. The primary actions of glucocorticoids are mediated by the glucocorticoid receptor (GR), a transcription factor that regulates many complex signaling pathways. Although GR is nearly ubiquitous throughout the body, glucocorticoids exhibit cell- and tissue-specific effects. For example, glucocorticoids stimulate glucose production in the liver, reduce glucose uptake in the skeletal muscle, and decrease insulin secretion from the pancreatic β-cells. Mouse models represent an important approach to understanding the dynamic functions of GR signaling in normal physiology, disease, and resistance. In the absence of a viable GR null model, gene-targeting techniques utilizing promoter-driven recombination have provided an opportunity to characterize the tissue-specific actions of GR. The aim of the present review is to describe the organ systems in which GR has been conditionally deleted and summarize the functions ascribed to glucocorticoid action in those tissues.

    Full Text Available Objective(s: Nanomaterials are playing major roles in imaging by delivering large imaging payloads, yielding improved sensitivity. Nanoparticles have enabled significant advances in pre-clinical cancer research as drug delivery vectors. Inorganic nanoparticles such as CdO/GrO nanoparticles have novel optical properties that can be used to optimize the signal-to-background ratio. This paper reports on a novel processing route for preparation of CdO/GrO nanolayer and investigation of its optical properties for application in in vivo targeting and imaging.Materials and Methods: Nanostructures were synthesized by reacting cadmium acetate and graphene powder. The effects ofdifferent parameters such as power and time of irradiation were also studied. Finally, the efficiency of CdO/GrO nanostructures as an optical composite was investigated using photoluminescence spectrum irradiation. CdO/GrO nanostructures were characterized by means of X-ray diffraction (XRD, atomic force microscopy (AFM, scanning electron microscopy (SEM, Fourier transform infrared (FT-IR and photoluminescence (PL spectroscopy.Results: According to SEM images, it was found that sublimation temperature had significant effect on morphology and layers. The spectrum shows an emission peak at 523 nm, indicating that CdO/GrO nanolayer can be used for in vivo imaging.Conclusion: The estimated optical band gap energy is an accepted value for application in in vivo imaging using a QD–CdO/GrO nanolayer.

  14. Expressions of Hippocampal Mineralocorticoid Receptor (MR) and Glucocorticoid Receptor (GR) in the Single-Prolonged Stress-Rats

    International Nuclear Information System (INIS)

    Zhe, Du; Fang, Han; Yuxiu, Shi

    2008-01-01

    Post-traumatic stress disorder (PTSD) is a stress-related mental disorder caused by traumatic experience. Single-prolonged stress (SPS) is one of the animal models proposed for PTSD. Rats exposed to SPS showed enhanced inhibition of the hypothalamo-pituitary-adrenal (HPA) axis, which has been reliably reproduced in patients with PTSD. Mineralocorticoid receptor (MR) and glucocorticoid receptor (GR) in the hippocampus regulate HPA axis by glucocorticoid negative feedback. Abnormalities in negative feedback are found in PTSD, suggesting that GR and MR might be involved in the pathophysiology of these disorders. In the present study, we performed immunohistochemistry and western blotting to examine the changes in hippocampal MR- and GR-expression after SPS. Immunohistochemistry revealed decreased MR- and GR-immunoreactivity (ir) in the CA1 of hippocampus in SPS animals. Change in GR sub-distribution was also observed, where GR-ir was shifted from nucleus to cytoplasm in SPS rats. Western blotting showed that SPS induced significantly decreased MR- and GR-protein in the whole hippocampus, although the degree of decreased expression of both receptors was different. Meanwhile, we also found the MR/GR ratio decreased in SPS rats. In general, SPS induced down-regulation of MR- and GR-expression. These findings suggest that MR and GR play critical roles in affecting hippocampal function. Changes in MR/GR ratio may be relevant for behavioral syndrome in PTSD

    In estrogen receptor (ER)-negative breast cancer (BC), high tumor glucocorticoid receptor (GR) expression has been associated with a relatively poor outcome. In contrast, using a meta-analysis of several genomic datasets, here we find that tumor GR mRNA expression is associated with improved ER+ relapse-free survival (RFS) (independently of progesterone receptor (PR) expression). To understand the mechanism by which GR expression is associated with a better ER+ BC outcome, the global effect of GR-mediated transcriptional activation in ER+ BC cells was studied. Analysis of GR chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) in ER+/GR+ MCF-7 cells revealed that upon co-activation of GR and ER, GR chromatin association became enriched at proximal promoter regions. Furthermore, following ER activation, increased GR chromatin association was observed at ER, FOXO, and AP1 response elements. In addition, ER associated with GR response elements, suggesting that ER and GR interact in a complex. Co-activation of GR and ER resulted in increased expression (relative to ER activation alone) of transcripts that encode proteins promoting cellular differentiation (e.g. KDM4B, VDR) and inhibiting the Wnt-signaling pathway (IGFBP4). Finally, expression of these individual pro-differentiation genes was associated with significantly improved RFS in ER+ BC patients. Together, these data suggest that the co-expression and subsequent activity of tumor cell GR and ER contribute to the less aggressive natural history of early-stage BC by coordinating the altered expression of genes favoring differentiation. Implications The interaction between estrogen and glucocorticoid receptor activity highlights the importance of context-dependent nuclear receptor function in cancer. PMID:27141101

    Animals use taste to sample and ingest essential nutrients for survival. Free fatty acids (FAs) are energy-rich nutrients that contribute to various cellular functions. Recent evidence suggests FAs are detected through the gustatory system to promote feeding. In Drosophila, phospholipase C (PLC) signaling in sweet-sensing cells is required for FA detection but other signaling molecules are unknown. Here, we show Gr64e is required for the behavioral and electrophysiological responses to FAs. GR64e and TRPA1 are interchangeable when they act downstream of PLC: TRPA1 can substitute for GR64e in FA but not glycerol sensing, and GR64e can substitute for TRPA1 in aristolochic acid but not N-methylmaleimide sensing. In contrast to its role in FA sensing, GR64e functions as a ligand-gated ion channel for glycerol detection. Our results identify a novel FA transduction molecule and reveal that Drosophila Grs can act via distinct molecular mechanisms depending on context. PMID:29420533

  18. The nature of the GRE influences the screening for GR-activity enhancing modulators.

    Full Text Available Glucocorticoid resistance (GCR, i.e. unresponsiveness to the beneficial anti-inflammatory activities of the glucocorticoid receptor (GR, poses a serious problem in the treatment of inflammatory diseases. One possible solution to try and overcome GCR, is to identify molecules that prevent or revert GCR by hyper-stimulating the biological activity of the GR. To this purpose, we screened for compounds that potentiate the dexamethasone (Dex-induced transcriptional activity of GR. To monitor GR transcriptional activity, the screen was performed using the lung epithelial cell line A549 in which a glucocorticoid responsive element (GRE coupled to a luciferase reporter gene construct was stably integrated. Histone deacetylase inhibitors (HDACi such as Vorinostat and Belinostat are two broad-spectrum HDACi that strongly increased the Dex-induced luciferase expression in our screening system. In sharp contrast herewith, results from a genome-wide transcriptome analysis of Dex-induced transcripts using RNAseq, revealed that Belinostat impairs the ability of GR to transactivate target genes. The stimulatory effect of Belinostat in the luciferase screen further depends on the nature of the reporter construct. In conclusion, a profound discrepancy was observed between HDACi effects on two different synthetic promoter-luciferase reporter systems. The favorable effect of HDACi on gene expression should be evaluated with care, when considering them as potential therapeutic agents. GEO accession number GSE96649.

    This study is the part of the Sunlight Absorption on the Greenland ice sheet Experiment (SAGE) project investigating the impact of light absorbing impurities (e.g., aerosols) on the Greenland Ice Sheet (GrIS). Satellite observations, [e.g. Oceansat-2 (OS2) and the Moderate-resolution Imaging Spectroradionmeter (MODIS)] discovered an unusually large melt event in July 2012. NASA sensors showed that nearly 98.6% of the GrIS experienced melting at or near surface [Nghiem et al., 2012]. In this study, we question the extent to which biomass burning derived aerosols enhanced melting across the GrIS. Random points [59 total, 13 coincident with snow pit sites and 46 gridded] are selected across the entire extent of the GrIS from April 1st to August 31st 2012, and then the NASA Langley Trajectory Model (LaTM) is used to simulate the transport of potentially smoke-filled air parcels backwards for 5 days form these points, evaluation the back trajectory for coincidence with active fire detections. The trajectory model is initialized for 24-hour sustained injection from each site, and air parcels are released from the surface to 2 km at 200m intervals. With the trajectory model outputs, we are able to identify trajectories that have coincidences with fires. We focus on events in April through July when the GrIS albedo was dramatically decreased. We also utilize Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) data to verify smoke-aerosol signatures in boreal regions based on the NASA LaTM results. The results of this study will help us better understand the transport of biomass burning plumes and black carbon deposition that could lead to enhanced GrIS melting.

  6. Converging shock flows for a Mie-Grüneisen equation of state

    Ramsey, Scott D.; Schmidt, Emma M.; Boyd, Zachary M.; Lilieholm, Jennifer F.; Baty, Roy S.

    2018-04-01

    Previous work has shown that the one-dimensional (1D) inviscid compressible flow (Euler) equations admit a wide variety of scale-invariant solutions (including the famous Noh, Sedov, and Guderley shock solutions) when the included equation of state (EOS) closure model assumes a certain scale-invariant form. However, this scale-invariant EOS class does not include even simple models used for shock compression of crystalline solids, including many broadly applicable representations of Mie-Grüneisen EOS. Intuitively, this incompatibility naturally arises from the presence of multiple dimensional scales in the Mie-Grüneisen EOS, which are otherwise absent from scale-invariant models that feature only dimensionless parameters (such as the adiabatic index in the ideal gas EOS). The current work extends previous efforts intended to rectify this inconsistency, by using a scale-invariant EOS model to approximate a Mie-Grüneisen EOS form. To this end, the adiabatic bulk modulus for the Mie-Grüneisen EOS is constructed, and its key features are used to motivate the selection of a scale-invariant approximation form. The remaining surrogate model parameters are selected through enforcement of the Rankine-Hugoniot jump conditions for an infinitely strong shock in a Mie-Grüneisen material. Finally, the approximate EOS is used in conjunction with the 1D inviscid Euler equations to calculate a semi-analytical Guderley-like imploding shock solution in a metal sphere and to determine if and when the solution may be valid for the underlying Mie-Grüneisen EOS.

    We present a detailed analysis of the effects of uniaxial and biaxial strain on the frequencies of the G mode of monolayer graphene, using first principles calculations. Our results allow us to explain discrepancies in the experimentally determined values of the Grüneisen parameter. The direction and strength of the applied strain, Poisson\\'s ratio of the substrate, and the intrinsic strain in different experimental setups turn out to be important. A reliable determination of the Grüneisen parameter is a prerequisite of strain engineering.

  17. Identification of direct targets of plant transcription factors using the GR fusion technique.

    Science.gov (United States)

    Yamaguchi, Nobutoshi; Winter, Cara M; Wellmer, Frank; Wagner, Doris

    2015-01-01

    The glucocorticoid receptor-dependent activation of plant transcription factors has proven to be a powerful tool for the identification of their direct target genes. In the absence of the synthetic steroid hormone dexamethasone (dex), transcription factors fused to the hormone-binding domain of the glucocorticoid receptor (TF-GR) are held in an inactive state, due to their cytoplasmic localization. This requires physical interaction with the heat shock protein 90 (HSP90) complex. Hormone binding leads to disruption of the interaction between GR and HSP90 and allows TF-GR fusion proteins to enter the nucleus. Once inside the nucleus, they bind to specific DNA sequences and immediately activate or repress expression of their targets. This system is well suited for the identification of direct target genes of transcription factors in plants, as (A) there is little basal protein activity in the absence of dex, (B) steroid application leads to rapid transcription factor activation, (C) no side effects of dex treatment are observed on the physiology of the plant, and (D) secondary effects of transcription factor activity can be eliminated by simultaneous application of an inhibitor of protein biosynthesis, cycloheximide (cyc). In this chapter, we describe detailed protocols for the preparation of plant material, for dex and cyc treatment, for RNA extraction, and for the PCR-based or genome-wide identification of direct targets of transcription factors fused to GR.

    We previously identified a gene, nuclear receptor-interaction protein (NRIP), which functions as a transcription cofactor in glucocorticoid receptor (GR) and human papillomavirus E2 (HPV E2)-driven gene expression. Here, we comprehensively evaluated the role of NRIP in HPV-16 gene expression. NRIP acts as a transcription cofactor to enhance GR-regulated HPV-16 gene expression in the presence of hormone. NRIP also can form complex with E2 that caused NRIP-induced HPV gene expression via E2-binding sites in a hormone-independent manner. Furthermore, NRIP can associate with GR and E2 to form tri-protein complex to activate HPV gene expression via GRE, not the E2-binding site, in a hormone-dependent manner. These results indicate that NRIP and GR are viral E2-binding proteins and that NRIP regulates HPV gene expression via GRE and/or E2 binding site in the HPV promoter in a hormone-dependent or independent manner, respectively.

    Strigolactones (SLs) are classified into plant hormones, playing a key role as a mediator of plant growth in response to several abiotic stresses, including drought and salinity. However, the role of SLs in cadmium (Cd)-induced stress to plants is still unknown. The physiological responses of switchgrass ( Panicum virgatum ) stressed in 10 μmol L -1 Cd to exogenous synthetic SLs analog, GR24 were studied in hydroponics. The Cd stress significantly caused the adverse effects on plant growth and root morphology, inhibited photosynthesis, but boosted lipid peroxidation of Switchgrass seedlings. After treatment of 1 μmol L -1 GR24, the above adverse effects caused by Cd stress were significantly alleviated, mainly reflects in improvement of shoot biomass, relative water content, root development, chlorophyll contents, activities of typical antioxidant enzymes, nutrient uptake. The reason for exogenous GR24 alleviating cadmium toxicity might be owing to that exogenous GR24 promoted the content of endogenous SLs, increased some essential element Fe (iron), Zn (zinc), Mn (manganese) and Cu (copper) uptake and reduced cadmium uptake, accumulation and partition in shoot of switchgrass seedlings.

  10. Modeling the Mechanism of GR/c-Jun/Erg Crosstalk in Apoptosis of Acute Lymphoblastic Leukemia.

    2012-01-01

    Acute lymphoblastic leukemia (ALL) is one of the most common forms of malignancy that occurs in lymphoid progenitor cells, particularly in children. Synthetic steroid hormones glucocorticoids (GCs) are widely used as part of the ALL treatment regimens due to their apoptotic function, but their use also brings about various side effects and drug resistance. The identification of the molecular differences between the GCs responsive and resistant cells therefore are essential to decipher such complexity and can be used to improve therapy. However, the emerging picture is complicated as the activities of genes and proteins involved are controlled by multiple factors. By adopting the systems biology framework to address this issue, we here integrated the available knowledge together with experimental data by building a series of mathematical models. This rationale enabled us to unravel molecular interactions involving c-Jun in GC induced apoptosis and identify Ets-related gene (Erg) as potential biomarker of GC resistance. The results revealed an alternative possible mechanism where c-Jun may be an indirect GR target that is controlled via an upstream repressor protein. The models also highlight the importance of Erg for GR function, particularly in GC sensitive C7 cells where Erg directly regulates GR in agreement with our previous experimental results. Our models describe potential GR-controlled molecular mechanisms of c-Jun/Bim and Erg regulation. We also demonstrate the importance of using a systematic approach to translate human disease processes into computational models in order to derive information-driven new hypotheses.

    2012-09-01

    Full Text Available A suppression subtractive hybridization (SSH approach was used to generate cDNA libraries representing genes differentially expressed in the haploid cells of the maize head smut pathogen Sporisorium reilianum exposed to GR24, a strigolactone analogue. Strigolactones are present in root exudates and have been known to trigger germination of parasitic plant seeds and signal mycorrhizal fungi to connect to root systems forming mutualistic relationships. Cell respiration increased within 1 h after GR24 addition, but decreased after 5 and 8 h. All induced cells were used to construct a cDNA library, which contained 1440 clones. The cDNA ESTs were deposited on macro-array membranes and hybridized with P32 cDNA probes obtained from mRNA isolated from S. reilianum yeast cultures exposed or not to 100 nM GR24 for three time intervals. A total of 678 ESTs were identified as differentially expressed during three time-courses in response to GR24. A set of 36 candidate genes were analyzed by qRT-PCR that presented an induction of the genes at 1 h, confirming the hybridization data. Induced genes mostly affect catalysis functions (45% like cell respiration (27%, and cell signaling (26%. Although the biological significance of this perception remains hypothetical, these results indicate that strigolactones could have a wider biological influence in the rhizosphere than previously recognized.

    In 1974, at the Medical Policlinic of the University of Zürich, German-born physician-scientist Andreas Grüntzig (1939-1985) for the first time applied a balloon-tipped catheter to re-open a severely stenosed femoral artery, a procedure, which he initially called "percutaneous transluminal dilatation". Balloon angioplasty as a therapy of atherosclerotic vascular disease, for which Grüntzig and Charles T. Dotter (1920-1985) received a nomination for the Nobel Prize in Physiology or Medicine in 1978, became one of the most successful examples of translational medicine in the twentieth century. Known today as percutaneous transluminal angioplasty (PTA) in peripheral arteries or percutaneous transluminal coronary angioplasty (PTCA) or percutaneous coronary intervention (PCI) in coronary arteries, balloon angioplasty has become the method of choice to treat patients with acute myocardial infarction or occluded leg arteries. On the occasion of the 40(th) anniversary of balloon angioplasty, we summarize Grüntzig's life and career in Germany, Switzerland, and the United States and also review the developments in vascular medicine from the 1890s to the 1980s, including Dotter's first accidental angioplasty in 1963. The work of pioneers of catheterization, including Pedro L. Fariñas in Cuba, André F. Cournand in France, Werner Forssmann, Werner Porstmann and Eberhard Zeitler in Germany, António Egas Moniz and Reynaldo dos Santos in Portugal, Sven-Ivar Seldinger in Sweden, and Barney Brooks, Thomas J. Fogarty, Melvin P. Judkins, Richard K. Myler, Dickinson W. Richards, and F. Mason Sones in the United States, is discussed. We also present quotes by Grüntzig and excerpts from his unfinished autobiography, statements of Grüntzig's former colleagues and contemporary witnesses, and have included hitherto unpublished historic photographs and links to archive recordings and historic materials. This year, on June 25, 2014, Andreas Grüntzig would have celebrated his 75(th

  17. The last developments of the airGR R-package, an open source software for rainfall-runoff modelling

    Lumped hydrological models are useful and convenient tools for research, engineering and educational purposes. They propose catchment-scale representations of the precipitation-discharge relationship. Thanks to their limited data requirements, they can be easily implemented and run. With such models, it is possible to simulate a number of hydrological key processes over the catchment with limited structural and parametric complexity, typically evapotranspiration, runoff, underground losses, etc. The Hydrology Group at Irstea (Antony) has been developing a suite of rainfall-runoff models over the past 30 years with the main objectives of designing models as efficient as possible in terms of streamflow simulation, applicable to a wide range of catchments and having low data requirements. This resulted in a suite of models running at different time steps (from hourly to annual) applicable for various issues including water balance estimation, forecasting, simulation of impacts and scenario testing. Recently, Irstea has developed an easy-to-use R-package (R Core Team, 2016), called airGR (Coron et al., 2016, 2017), to make these models widely available. It includes: - the water balance annual GR1A model, - the monthly GR2M model, - three versions of the daily model, namely GR4J, GR5J and GR6J, - the hourly GR4H model, - a degree-day snow model CemaNeige. The airGR package has been designed to facilitate the use by non-expert users and allow the addition of evaluation criteria, models or calibration algorithm selected by the end-user. Each model core is coded in FORTRAN to ensure low computational time. The other package functions (i.e. mainly the calibration algorithm and the efficiency criteria) are coded in R. The package is also used for educational purposes. It allows for convenient implementation of model inter-comparisons and large sample hydrology experiments. The airGR package undergoes continuous developments for improving the efficiency, computational time

A dieta com substituição total dos grãos de milho seco por silagem de grãos de milho úmidos apresentou maior ganho de peso aos 73 dias em relação àqueles obtidos aos 56 e 28 dias de confinamento. Este fato pode ser explicado pela melhor digestibilidade apresentada pelas silagens, atribuída à gelatinização que o amido sofre durante o processo. Assim, a silagem de grãos úmidos pode ser usada com eficácia em dietas para cordeiros.

    We present extensive optical observations of the normal Type Ic supernova (SN) 2007gr, spanning from about one week before maximum light to more than one year thereafter. The optical light and color curves of SN 2007gr are very similar to those of the broad-lined Type Ic SN 2002ap, but the spectra show remarkable differences. The optical spectra of SN 2007gr are characterized by unusually narrow lines, prominent carbon lines, and slow evolution of the line velocity after maximum light. The earliest spectrum (taken at t = –8 days) shows a possible signature of helium (He I λ5876 at a velocity of ∼19,000 km s –1 ). Moreover, the larger intensity ratio of the [O I] λ6300 and λ6364 lines inferred from the early nebular spectra implies a lower opacity of the ejecta shortly after the explosion. These results indicate that SN 2007gr perhaps underwent a less energetic explosion of a smaller-mass Wolf-Rayet star (∼8-9 M ☉ ) in a binary system, as favored by an analysis of the progenitor environment through pre-explosion and post-explosion Hubble Space Telescope images. In the nebular spectra, asymmetric double-peaked profiles can be seen in the [O I] λ6300 and Mg I] λ4571 lines. We suggest that the two peaks are contributed by the blueshifted and rest-frame components. The similarity in velocity structure and the different evolution of the strength of the two components favor an aspherical explosion with the ejecta distributed in a torus or disk-like geometry, but inside the ejecta the O and Mg have different distributions.

  10. Characterization of the theta replication plasmid pGR7 from Acetobacter aceti CCM 3610.

    Grones, Peter; Grones, Jozef

    2012-07-01

    A cryptic plasmid of Acetobacter aceti CCM 3610, designated pGR7, was sequenced and characterized. It is a 2446-bp circular molecule with a G + C content of 30%, which is unusual when compared to the already known plasmids isolated from Acetobacter genera. Sequence analysis of pGR7 revealed three putative open reading frames (ORFs). ORF1 displays low similarity with other Acetobacter plasmid replication proteins. The other two ORFs show similarities only to hypothetical proteins and do not encode any important protein. The replication module comprises a DnaA box-like sequence, indirect repeats, a potential prokaryotic promoter and the rep gene. The rep module organization is similar to that found in other theta-replicating plasmids from acetic acid bacteria that stably maintain in both Acetobacter and Escherichia coli, with two repeated sequences containing modules. Nevertheless, the pGR7 plasmid could replicate and be stably maintained only in Acetobacter strains and not in E. coli, another uncommon feature of this plasmid. The Rep protein was cloned into the pET30a + expression vector and purified by high-performance liquid chromatography. The helicase activity was determined and the ability of the protein to bind to the plasmid regulation region was confirmed by an electrophoretic mobility shift assay. The plasmid was stable in the Acetobacter cells after cultivation under nonselective conditions. By real-time polymerase chain reaction, the relative copy number of pGR7 was estimated to be seven copies per host chromosome equivalent. Copyright © 2012 Institut Pasteur.

    Full Text Available Parasitic plants of genera Orobanche and Phelipanche germinate after exposition to chemical signals exuded by roots of the host plants. The most studied germination stimulants belong to strigolactones (SLs, the newly discovered plant hormones which are stimulating hyphal branching of arbuscular mycorrhizal fungi and are involved in regulation of shoot and root architecture of plants. However, little is known about the effect of strigolactones on germination of non-weedy broomrapes. The objective of our study was to investigate the sensitivity of seeds of non-weedy broomrapes to synthetic analogue of SLs, GR24. The seeds of non-weedy broomrapes Orobanche alba, O. alsatica, O. caryophyllacea, O. elatior, O. flava, O. lutea, O. pallidiflora, O. reticulata, Phelipanche arenaria, P. purpurea and weedy species P. ramosa were collected in natural and cropland plant communities in Slovakia. Seeds of P. ramosa and P. purpurea were highly sensitive to GR24. On the other hand, effectivity of GR24 in inducing germination of several wild species, O. alba, O. caryophyllacea and P. arenaria was low, while the stimulant shown to be completely not effective on other non-weedy species O. alsatica, O. elatior, O. flava, O. lutea, O. pallidiflora, and O. reticulata. The results point out there are differences in the requirement for germination signals that possibly depend on the host.

    Nous rapportons un cas exceptionnel de volvulus nécrosé de l'intestin grêle dû à des ascaris adultes chez un enfant de 7 ans. A l'admission, l'enfant présentait le tableau d'occlusion intestinale qui évoluait depuis deux jours avec altération de l'état général. La radiographie de l'abdomen sans préparation retrouvait des niveaux hydroaériques de type grêlique et un aspect tigré évoquant le diagnostic d'une occlusion intestinale haute sur masse abdominale. Après la réanimation, le traitement chirurgical consistait en une laparotomie qui avait retrouvé un volvulus nécrosé de l'iléon terminale contenant des ascaris adultes. Une résection du grêle sur environ un mètre emportant le segment nécrosé suivie d'une iléostomie était réalisée. L'évolution a été favorable, l'anastomose iléo-colique fut réalisée quatre semaines plus tard. Au recul de deux ans l'enfant est indemne de tout symptôme. PMID:27795803

    Gas phase abundances are one of the best measures of the intrinsic metallicity of low mass galaxies. We recently obtained low resolution long slit optical spectra of several HII regions in Leo A and GR 8 with the Palomar 5m telescope. Previous studies of the resolved stellar population of Leo A indicated that the stars have metallicities approximately 2% of solar (Tolstoy et al. 1998). Preliminary analysis of the HII region spectra, and that of a planetary nebula, indicates that the gas phase oxygen abundance of Leo A is approximately 3% of solar. This confirms the result of Skillman et al. (1989), who also derived an oxygen abundance for Leo A from a planetary nebula. Similarly, for GR 8 we find a mean oxygen abundance of 5% of solar. For all the HII regions, the derived log(N/O) is -1.5 +/- 0.1, as has been found for other low metallicity systems. These new observations of multiple HII regions in Leo A and GR 8 confirm that metals in low mass galaxies are well mixed.

    Full Text Available The present research deals with development and characterisation of magnesium–SiC–Gr hybrid composites through powder metallurgy route. Morphology analysis of the magnesium and reinforcement powder particles has been carried out using particle size analyser (PSA and X-ray diffraction (XRD, and then the mixed powders were analysed through scanning electron microscope (SEM. The developed composite exhibit increased hardness when compared to base material, which could be attributed to the presence of hard SiC. Furthermore, a slight decrease in hardness is observed for the hybrid composite when compared to Mg–SiC composite due to the presence of soft Gr particles. The tribological properties of the developed composite materials were investigated using pin-on-disc wear test apparatus under dry sliding conditions. The wear resistance of the developed composites improved significantly than that of the magnesium matrix due to the upright effect offered by both of the reinforcements. The SEM analysis was carried out on the worn out surfaces for better understanding of wear mechanisms. 5% Gr reinforced Mg-10SiC composites confer better wear resistance among the developed composites.

O delineamento empregado foi o "change-over", com dois grupos de três animais em período experimental de 84 dias. A ração era composta de farelo de soja (14 %, milho em grãos (26 % e feno (60 %, medindo-se digestibilidade total e "in situ" do milho e do feno parâmetros ruminais: pH, N-NH3 e cinética de líquidos. Os resultados mostraram menores taxas de degradabilidade da matéria seca e proteína bruta do milho quando fornecido grosseiramente quebrado. Não ocorreram influências dos tratamentos sobre a fibra do feno ou sobre parâmetros ruminais. Concluiu-se que, no interior do rúmen, grãos de milho finamente moídos tiveram maior digestibilidade sem provocar alterações na digestão da fibra.

  19. Creep and Creep Crack Growth Behaviors for SMAW Weldments of Gr. 91 Steel

    High Cr ferritic resistance steels with tempered martensite microstructures posses enhanced creep strength at the elevated temperatures. Those steels as represented by a modified 9Cr-1Mo steel (ASME Grade 91, hereafter Gr.91) are regarded as main structural materials of sodium-cooled fast reactors (SFR) and reactor pressure vessel materials of very high temperature reactors (VHTR). The SFR and VHTR systems are designed during long-term duration reaching 60 years at elevated temperatures and often subjected to non-uniform stress and temperature distribution during service. These conditions may generate localized creep damage and propagate the cracks and ultimately may cause a fracture. A significant portion of its life is spent in crack propagation. Therefore, a creep crack growth rate (CCGR) due to creep damage should be assessed for both the base metal (BM) and welded metal (WM). Enough CCGR data for them should be provided for assessing their structural integrities. However, their CCGR data for the Gr. 91 steels is still insufficient. In this study, the CCGR for the BM and the WM of the Gr. 91 steel was comparatively investigated. A series of the CCG tests were conducted under different applied loads for the BM and the WM at 600 .deg. C. The CCGR was characterized in terms of the C parameter, and their CCG behavior were compared, respectively

    The class of type Ic supernovae have drawn increasing attention since 1998 owing to their sparse association (only four so far) with long duration gamma-ray bursts (GRBs). Although both phenomena originate from the core collapse of a massive star, supernovae emit mostly at optical wavelengths, whereas GRBs emit mostly in soft gamma-rays or hard X-rays. Though the GRB central engine generates ultra-relativistic jets, which beam the early emission into a narrow cone, no relativistic outflows have hitherto been found in type Ib/c supernovae explosions, despite theoretical expectations and searches. Here we report radio (interferometric) observations that reveal a mildly relativistic expansion in a nearby type Ic supernova, SN 2007gr. Using two observational epochs 60 days apart, we detect expansion of the source and establish a conservative lower limit for the average apparent expansion velocity of 0.6c. Independently, a second mildly relativistic supernova has been reported. Contrary to the radio data, optical observations of SN 2007gr indicate a typical type Ic supernova with ejecta velocities approximately 6,000 km s(-1), much lower than in GRB-associated supernovae. We conclude that in SN 2007gr a small fraction of the ejecta produced a low-energy mildly relativistic bipolar radio jet, while the bulk of the ejecta were slower and, as shown by optical spectropolarimetry, mildly aspherical.

The article concludes that earlier anti-Semitic expressions, visible in the negative and nationalistically oriented criticism, have been incorporated into Hintze’s ambivalent, but basically positive, characterization of Grünewald. In doing so Hintze translocate the anti-Semitic rhetoric from a negative and disparaging criticism into ‘normal’ art history, an example of how the voice of anti-Semitism have been built into the language and structure of Swedish art historiography, even where anti-Semitism was not the object.

    A challenging issue in General Relativity concerns the determination of the manifestly covariant continuum Hamiltonian structure underlying the Einstein field equations and the related formulation of the corresponding covariant Hamilton-Jacobi theory. The task is achieved by adopting a synchronous variational principle requiring distinction between the prescribed deterministic metric tensor g(r) ≡ {g_μ_ν(r)} solution of the Einstein field equations which determines the geometry of the background space-time and suitable variational fields x ≡ {g,π} obeying an appropriate set of continuum Hamilton equations, referred to here as GR-Hamilton equations. It is shown that a prerequisite for reaching such a goal is that of casting the same equations in evolutionary form by means of a Lagrangian parametrization for a suitably reduced canonical state. As a result, the corresponding Hamilton-Jacobi theory is established in manifestly covariant form. Physical implications of the theory are discussed. These include the investigation of the structural stability of the GR-Hamilton equations with respect to vacuum solutions of the Einstein equations, assuming that wave-like perturbations are governed by the canonical evolution equations.

    Full Text Available Let be a polynomial with only real zeros having , as consecutive zeros. It was proved by P. Erdős and T. Grünwald that if on , then the ratio of the area under the curve to the area of the tangential rectangle does not exceed . The main result of our paper is a multidimensional version of this result. First, we replace the class of polynomials considered by Erdős and Grünwald by the wider class consisting of functions of the form , where is logarithmically concave on , and show that their result holds for all functions in . More generally, we show that if and , then for all , the integral does not exceed . It is this result that is extended to higher dimensions. Our consideration of the class is crucial, since, unlike the narrower one of Erdős and Grünwald, its definition does not involve the distribution of zeros of its elements; besides, the notion of logarithmic concavity makes perfect sense for functions of several variables.

    Full Text Available O resfriamento artificial é uma ferramenta para conservação da qualidade de grãos nas regiões tropicais. Este trabalho foi realizado com o propósito de verificar o efeito da refrigeração artificial do ar, por meio de aeração, na preservação da qualidade de grãos de milho em armazém graneleiro horizontal, de fundo "V". Para o experimento foram utilizados dois septos, sendo um resfriado artificialmente (12ºC, com capacidade de 28 mil toneladas, e o outro aerado com ar natural, com capacidade de 29 mil toneladas. As amostragens foram realizadas, em ambos os septos, durante a carga, aos 60 e 120 dias após a primeira etapa de resfriamento e durante a expedição dos grãos. Durante o armazenamento, as amostragens foram realizadas considerando-se a posição e a profundidade da massa de grãos de milho. A avaliação qualitativa consistiu na determinação dos seguintes parâmetros: peso de mil grãos, temperatura da massa de grãos, teor e acidez de óleo, identificação de fungos, teor de aflatoxina, índice de infestação de insetos e porcentagem de grãos infestados. O resfriamento artificial promoveu a diminuição da temperatura da massa de grãos, independentemente das condições de temperatura e umidade do ar externo. A aeração artificial, com ar frio, preservou os parâmetros atribuídos à qualidade dos grãos e proporcionou redução na percentagem de grãos infestados e na população de insetos-praga na massa do produto. Assim, a utilização do resfriamento artificial no armazenamento de grãos de milho em regiões tropicais é eficaz na manutenção da qualidade dos grãos e no manejo de insetos e patógenos.

Os experimentos foram instalados no Núcleo Experimental do Instituto Agronômico, em Campinas, SP, no período de 1996 a 1998. A germinação na espiga foi avaliada pelo método do "Falling Number", que consiste em determinar o nível de atividade da alfa-amilase nos grãos. A segunda e a terceira colheitas foram realizadas ao sete e quatorze dias após a primeira colheita. O atraso da colheita determinou redução no rendimento, notadamente na terceira colheita; os teores de alfa-amilase foram maiores também na terceira colheita, em virtude da degradação dos grãos expostos ao tempo. O genótipo IAC 289 apresentou adaptabilidade a ambientes favoráveis, mas apresentou suscetibilidade à ocorrência de germinação dos grãos na espiga. Os genótipos IAC 24, Mochis, IAC 370 e IAC 351 foram os mais resistentes à germinação dos grãos na espiga, apresentando baixa atividade de alfa-amilase.

    We have investigated the past light history of the luminous variable star GR 290 (M33/V532, Romano’s Star) in the M33 galaxy, and collected new spectrophotometric observations in order to analyze links between this object, the LBV category, and the Wolf–Rayet stars of the nitrogen sequence. We have built the historical light curve of GR 290 back to 1901, from old observations of the star found in several archival plates of M33. These old recordings together with published and new data on the star allowed us to infer that for at least half a century the star was in a low luminosity state, with B ≃ 18–19, most likely without brighter luminosity phases. After 1960, five large variability cycles of visual luminosity were recorded. The amplitude of the oscillations was seen increasing toward the 1992–1994 maximum, then decreasing during the last maxima. The recent light curve indicates that the photometric variations have been quite similar in all the bands and that the B – V color index has been constant within ±0.1{sup m} despite the 1.5{sup m} change of the visual luminosity. The spectrum of GR 290 at the large maximum of 1992–94 was equivalent to late-B-type, while, during 2002–2014, it varied between WN10h-11h near the visual maxima to WN8h-9h at the luminosity minima. We have detected, during this same period, a clear anti-correlation between the visual luminosity, the strength of the He ii 4686 Å emission line, the strength of the 4600–4700 Å lines’ blend, and the spectral type. From a model analysis of the spectra collected during the whole 2002–2014 period, we find that the Rosseland radius R {sub 2/3}, changed between the minimum and maximum luminosity phases by a factor of three while T {sub eff} varied between about 33,000 and 23,000 K. We confirm that the bolometric luminosity of the star has not been constant, but has increased by a factor of ∼1.5 between minimum and maximum luminosity, in phase with the apparent luminosity

    Full Text Available The high-temperature plastic deformation and dynamic recrystallization behavior of SA508Gr.4N steel were investigated through hot deformation tests in a Gleeble1500D thermal mechanical simulator. The compression tests were performed in the temperature range of 1050-1250℃ and the strain rate range of 0.001-0.1s-1 with true strain of 0.16. The results show that from the high-temperature true stress-strain curves of the SA508Gr.4N steel, the main feature is dynamic recrystallization,and the peak stress increases with the decrease of deformation temperature or the increase of strain rate, indicating the experimental steel is temperature and strain rate sensitive material. The constitutive equation for SA508Gr.4N steel is established on the basis of the true stress-strain curves, and exhibits the characteristics of the high-temperature flow behavior quite well, while the activation energy of the steel is determined to be 383.862kJ/mol. Furthermore, an inflection point is found in the θ-σ curve, while the -dθ/dσ-σ curve shows a minimum value. The critical strain increases with increasing strain rate and decreasing deformation temperature. A linear relationship between critical strain (εc and peak strain (εp is found and could be expressed as εc/εp=0.517. The predicted model of critical strain could be described as εc=8.57×10-4Z0.148.

    Full Text Available Abstract Background Murine gammaherpesvirus 68 (HV-68 is an efficient pathogen, capable of infecting and establishing lifelong latency in rodents. While many studies have demonstrated the ability of this viral infection to modulate immune responses, a unifying mechanism for HV-68-induced subversion of a protective host response remains elusive. We questioned whether infection with HV-68 could expand a population of myeloid derived suppressor cells (MDSC as one mechanism for altering protective immunity. Methods Mice were infected with HV-68, with viral latency being established in these animals. At varying times post-infection, cells were isolated for detection of viral genomes, phenotyping of myeloid cell populations, and ex vivo analysis of suppressor activity of myeloid cells. Results CD11b + Gr-1+ myeloid cells accumulated in the spleens, but not the bone marrow, of HV-68 infected mice. These cells were predominantly Gr-1+ Ly-6 G+, and could be found to contain viral genomes. Increased levels of serum S100A8/A9 produced during viral infection were consistent with the expansion of these CD11b + Gr-1+ myeloid cells. Despite their expansion, these cells exhibited no increased arginase 1 or iNOS activity, and did not have the ability to suppress anti-CD3 antibody activated T lymphocyte responses. Conclusions We concluded that HV-68 infection was capable of expanding a population of myeloid cells which were phenotypically similar to MDSC. However these cells were not sufficiently activated during the establishment of viral latency to actively suppress T cell responses.

    2016-09-01

    The goal of this work is to develop software that enables the rapid implementation of custom MRI spectrometers using commercially-available software defined radios (SDRs). The developed gr-MRI software package comprises a set of Python scripts, flowgraphs, and signal generation and recording blocks for GNU Radio, an open-source SDR software package that is widely used in communications research. gr-MRI implements basic event sequencing functionality, and tools for system calibrations, multi-radio synchronization, and MR signal processing and image reconstruction. It includes four pulse sequences: a single-pulse sequence to record free induction signals, a gradient-recalled echo imaging sequence, a spin echo imaging sequence, and an inversion recovery spin echo imaging sequence. The sequences were used to perform phantom imaging scans with a 0.5 Tesla tabletop MRI scanner and two commercially-available SDRs. One SDR was used for RF excitation and reception, and the other for gradient pulse generation. The total SDR hardware cost was approximately 2000. The frequency of radio desynchronization events and the frequency with which the software recovered from those events was also measured, and the SDR's ability to generate frequency-swept RF waveforms was validated and compared to the scanner's commercial spectrometer. The spin echo images geometrically matched those acquired using the commercial spectrometer, with no unexpected distortions. Desynchronization events were more likely to occur at the very beginning of an imaging scan, but were nearly eliminated if the user invoked the sequence for a short period before beginning data recording. The SDR produced a 500 kHz bandwidth frequency-swept pulse with high fidelity, while the commercial spectrometer produced a waveform with large frequency spike errors. In conclusion, the developed gr-MRI software can be used to develop high-fidelity, low-cost custom MRI spectrometers using commercially-available SDRs.

This scheme is shown to be second-order accurate under certain modifications to account for poor accuracy in approximating the asymptotic behavior near the lower limit of differentiation. Some example functions are chosen and numerical results are presented to illustrate the efficacy of this new method over some other popular choices for discretizing fractional derivatives.

    Quality of sleep in patients with cancer is regarded as of utmost importance. The aim of the present study was to assess psychometric properties and feasibility of the Greek version of the Pittsburgh Sleep Quality Index (GR-PSQI). Following a "forward-backward" procedure, the scale was translated into Greek. The GR-PSQI was administered as a self-report instrument to 209 consecutive patients with cancer during active-phase chemotherapy treatment. For stability analysis purposes, a subgroup of 60 patients completed the GR-PSQI on two occasions, 14-21 days apart. All participants also completed the Insomnia Severity Index, the Epworth Sleepiness Scale-Greek version, a Sleep Quality-Visual Analogue Scale and the Hospital Anxiety and Depression Scale-Greek version. Validity and reliability analyses were performed for GR-PSQI data. The Chronbach's alpha for the global GR-PSQI score was 0.76. Test-retest reliability analysis for the global GR-PSQI score yielded a high intra-class correlation coefficient of 0.82 (p quality of nocturnal sleep] and [daily disturbances and management of sleep problems]. This construct was further supported by its high correlations with similar content instruments, as well as by the instrument's ability to discriminate well between contrasting groups of patients with different levels of anxiety, depression and performance status. The present findings support the GR-PSQI as a reliable, stable over time and valid sleep quality instrument when administered to patients with cancer during chemotherapy treatment; however, it is suggested that the use of a two-factor scoring method (instead of the traditional unidimensional) could improve its sensitivity in this patient group.

  18. airGR: a suite of lumped hydrological models in an R-package

    2016-04-01

    Lumped hydrological models are useful and convenient tools for research, engineering and educational purposes. They propose catchment-scale representations of the precipitation-discharge relationship. Thanks to their limited data requirements, they can be easily implemented and run. With such models, it is possible to simulate a number of hydrological key processes over the catchment with limited structural and parametric complexity, typically evapotranspiration, runoff, underground losses, etc. The Hydrology Group at Irstea (Antony) has been developing a suite of rainfall-runoff models over the past 30 years with the main objectives of designing models as efficient as possible in terms of streamflow simulation, applicable to a wide range of catchments and having low data requirements. This resulted in a suite of models running at different time steps (from hourly to annual) applicable for various issues including water balance estimation, forecasting, simulation of impacts and scenario testing. Recently, Irstea has developed an easy-to-use R-package (R Core Team, 2015), called airGR, to make these models widely available. It includes: - the water balance annual GR1A (Mouehli et al., 2006), - the monthly GR2M (Mouehli, 2003) models, - three versions of the daily model, namely GR4J (Perrin et al., 2003), GR5J (Le Moine, 2008) and GR6J (Pushpalatha et al., 2011), - the hourly GR4H model (Mathevet, 2005), - a degree-day snow module CemaNeige (Valéry et al., 2014). The airGR package has been designed to facilitate the use by non-expert users and allow the addition of evaluation criteria, models or calibration algorithms selected by the end-user. Each model core is coded in FORTRAN to ensure low computational time. The other package functions (i.e. mainly the calibration algorithm and the efficiency criteria) are coded in R. The package is already used for educational purposes. The presentation will detail the main functionalities of the package and present a case

    2010-07-01

    In April 2009 the web site under the title darksky.gr went online. This site is an attempt to communicate the problem of light pollution to the public. Light pollution is treated not as an isolated problem but as part of a more general and complex issue which affects the environment, energy resources and human health. Darksky.gr aims to become a meeting point and unite the efforts of Greek amateur astronomy clubs and other organizations interested in the issue such as scientific societies, environmental organizations, technical chambers, mass media and private companies involved in electricity and lighting. Its creation has been suggested by the Astronomical Society of Patras “Orion” and ratified in the annual meeting of Greek amateur astronomy clubs that took place in Alexandroupoli in November 2008. We believe that amateur astronomy clubs represent a very active cell in the field of scientific knowledge communication to the public and that they can play an important role in raising awareness of the problem in cooperation with active organizations in related fields. The goal is to launch a wide cooperation between interested parties targeting to prevent the increasing light pollution. In this work, the goals and methods of the campaign are analyzed and an attempt to assess the very first results is made.

    2004-01-01

    GRCop-84 is a copper-chromium-niobium alloy developed by the Glenn Research Center for liquid rocket engine combustion chamber liners. GRCop-84 exhibits superior properties over conventional copper-base alloys in a liquid hydrogen-oxygen operating environment. The Next Generation Launch Technology program has funded a program to demonstrate scale-up production capabilities of GR-Cop 84 to levels suitable for main combustion chamber production for the prototype rocket engine. This paper describes a novel method of manufacturing the main combustion chamber liner. The process consists of several steps: extrude the GR-Cop 84 powder into billets, roll the billets into plates, bump form the plates into cylinder halves and friction stir weld the halves into a cylinder. The cylinder is then metal spun formed to near net liner dimensions followed by finish machining to the final configuration. This paper describes the friction stir weld process development including tooling and non-destructive inspection techniques, culminating in the successful production of a liner preform completed through spin forming.

    Full Text Available O avanço tecnológico tem tornado os processos produtivos cada vez mais robustos (robustos no sentido de produzirem itens cada vez mais iguais. Neste contexto, pequenas alterações no processo podem ser críticas, devendo portanto ser eliminadas com rapidez. Tradicionalmente, são utilizados os gráficos das somas acumuladas ou das médias móveis para controlar tais processos. O objetivo deste trabalho é mostrar que os gráficos de Shewhart também podem ser utilizados para controlar processos robustos, bastando variar seus parâmetros de projeto de maneira apropriada.Technological development has reduced the variability between items produced on s large scale. Today, a small change in the process can be critical, requiring rapid action to eliminate it. Traditionally, the CUSUM and the moving mean are the charts used to control these processes that we call robust processes. The aim of this paper is to show that the Shewhart chart can also be used to control robust processes, if the constraint of fixed design parameters is relaxed.

  5. A state-space representation of the GR4J rainfall-runoff model

    Santos, Léonard; Thirel, Guillaume; Perrin, Charles

    2017-04-01

    In hydrology, the majority of conceptual models are available only in discrete form. This means that the formulations of the models are based on discrete equations instead of continuous ordinary differential equations (ODE) (see Clark and Kavetski, 2010). The time-step is often "hardcoded" in the model formulation. This can represent a problem in particular for creating a time step-variable model. Furthermore, the fluxes in the models are treated sequentially. For example, in the simple GR4J model, the precipitations (if any) are first added to the production store. Then, the updated level is used to compute the percolation from the store. The resulting level obtained at the end of the time step is different to the level which would be obtained if the two operations (i.e. addition of precipitation and percolation) were done simultaneously. Mathematically, this corresponds to an approximation of ODE solution which is called "operator splitting". This allows to solve an equation even if finding an exact solution is impossible but the error produced by this approximation is difficult to determine. For this reason, it is not easy to separate the numerical error of the resolution from the conceptual error. It could represent an important issue to better understand model behaviour and to identify possible improvements. The aim of this presentation is to detail a state-space representation of the simple GR4J model. The state-space representation aims to represent GR4J by an ODE system which provides the internal variables of the model at all times. We will present here the choices made to adapt GR4J to the state-space formulation and to numerically solve this system. Modifications of the model's equations were also made to adapt the model to lower time step in case it would be used for a time step-variable application. The results obtained with this state-space representation of GR4J were very similar to those of the original model in terms of performances and hydrographs

  6. Differential GR Expression and Translocation in the Hippocampus Mediates Susceptibility vs. Resilience to Chronic Social Defeat Stress

    Full Text Available While social stress exposure is a common risk factor for affective disorders, most individuals exposed to it can maintain normal physical and psychological functioning. However, factors that determine susceptibility vs. resilience to social stress remain unclear. Here, the resident-intruder model of social defeat was used as a social stressor in male C57BL/6J mice to investigate the difference between susceptibility and resilience. As depression is often characterized by hyperactivity of the hypothalamic-pituitary-adrenal (HPA axis, we conducted the present study to further investigate the individual differences in the HPA axis response and glucocorticoid receptor (GR protein expression and translocation between susceptible mice and resilient mice. We found that hypercortisolemia, induced by social defeat stress occurred in susceptible mice, but not in resilient mice. Moreover, susceptible mice exhibited significantly less GR protein expression and nuclear translocation in the hippocampus than resilient mice. Treatment with escitalopram could decrease the serum corticosterone (CORT, increase GR protein expression as well as nuclear translocation in the hippocampus and ultimately reverse social withdrawal behaviors in susceptible mice. These results indicate that the up-regulation of GR and the enhancement of GR nuclear translocation in the hippocampus play an important role in resilience to chronic social defeat stress.

    Full Text Available The proton irradiation behaviors of two kinds of SA-738Gr.B steels prepared by different heat treatment used as AP1000 reactor containment were investigated by transmission electron microscopy and positron annihilation lifetime spectrum (PAS. The mechanical properties of as-received steels were also measured. In the unirradiated conditions, the SA-738Gr.B steels had high tensile strength and excellent impact fracture toughness, which met the performance requirements of ASME codes. Both kinds of SA-738Gr.B steels were irradiated by 400keV proton from 1.07×1017H+/cm2 to 5.37×1017H+/cm2 fluence at 150 ºC. Some voids and dislocation loops with several nanometers were observed in the cross-section irradiated samples prepared by electroplating and then twin-jet electropolishing technology. The number of irradiation defects increased with increasing of displacement damage, as well as for the mean positron lifetimes. The stress-relief annealing treatment improved irradiation resistance based on open volume defect analysis from proton irradiation. SA-738Gr.B (SR steel had higher proton irradiation resistance ability than that of SA-738Gr.B (QT steel. The mechanism of irradiation behaviors were also analyzed and discussed.

    Full Text Available Cortisol is the main corticosteroid secreted by the interrenal cells of the head kidney and it exerts a role in mantaining the omeostatic status in fish. In teleosts its effects are mediated through intracellular receptors expressed in several tissues, that are ligand-dependent transcription factors by binding to specific tissue DNA sequences. In Dicentrarchus labrax we previously cloned and sequenced a glucocorticoid receptor, DlGR1, isolated from leukocytes of peritoneal cavity. In this work we showed mRNA expression and tissue immunohistochemical localization of brain DlGR1 by in situ hybridization assays, with a riboprobe with DlGR1 cDNA trascriptional activation domain, and by immunohistochemical methods, using a specific antibody for a selected sequence of the receptor tran- scriptional domain. The mRNA and the protein are expressed in pyramidal cells of the optic lobe and in the small globular neurons of the diencephalon.

  14. Temperature regime of upper layer of the glacier East Grönfjordbreen (West Svalbard

    Directory of Open Access Journals (Sweden)

    R. A. Chernov

    2015-01-01

    Full Text Available Data of thermometry performed in boreholes of the glacier East Grönfjordbreen situated in West Svalbard are presented. The measurements were made within the ice upper layer down to 20 m in spring and summer of 2012–2014. Basing on the temperature distribution in the boreholes the following heat balance elements of the active ice layer were calculated: winter storage of cold, heat losses for thawing and warming of snow and ice. It was found that the main influence on storage of cold in the upper ice layer is exerted by thickness of the snow cover and the summer ablation. Comparison between winter and summer storages of the cold allows drawing the conclusion that the most intensive cooling takes place in central part of the glacier where the snow accumulation is small and the ablation is moderate.

  16. The construction of the graphite calorimeter GR9 at LNE-LNHB (geometrical and technical consideration)

    International Nuclear Information System (INIS)

    Ostrowsky, A.; Daures, J.

    2008-01-01

    Calorimetry is the most direct dosimetric technique to reach absorbed dose. A calorimeter gives direct access to the energy imparted to matter by ionizing radiation per mass unit by measuring the heat quantity Q produced under irradiation in its sensitive element which is thermally insulated. Graphite was chosen as construction material because all the energy imparted to graphite by ionizing radiation is converted into heat. Thermistors are used for temperature measurements as well as for the electrical heating of the different bodies of the calorimeter. The construction of a calorimeter is the result of a compromise between dosimetric requirements and mechanical constraints. The difficulties encountered are examined and the solutions chosen are detailed. All technical data are gathered in this document. The aim is to provide a practical operative instruction and guidance document, which can help interested laboratories in designing such an instrument. The electrical and thermal tests have shown a good behaviour of the GR9 calorimeter

    Children's use of the Internet has significantly risen in the last decade. Nevertheless, children spend a lot of time online which makes them susceptible to various threats (such as inappropriate material, offensive language, etc). Parents are the last frontier to this menace but they also need to be educated and trained in order to protect their children. Goneis.gr is an initiative launched by the Greek government that aims to educate parents on safer Internet and the use of parental control software.

    This paper presents the evaluation of microbiological corrosion susceptibility of carbon steel SA106gr.B in raw water. The experiment consisted of a series of electrochemical accelerated tests which evaluated the pitting corrosion susceptibility and determined corrosion rates before and after the immersion. The microbiological analysis of the water determined the types of bacteria and bacterial concentration present in water and in biofilms. Microbiological analysis of the water sample emphasized the existence, in small numbers (10-101 ml-1), of heterotrophic aerobic bacteria, sulphate-reducing bacteria and iron-oxidizing microorganisms. Along with sulphate-reducing bacteria, the heterotrophic aerobic bacteria and the iron-oxidizing microorganisms are categorized as having an important role in the corrosion of metals, including steel. The surfaces of the tested samples were analysed using the optical and electronic microscope, and emphasized the role of bacteria in the development of biofilms under which appeared characteristics of corrosion attack.

    Insects taste nonvolatile chemicals through gustatory receptors (Grs) and make choices for feeding, mating, and oviposition. To date, genome projects have identified 69 Gr genes in the silkworm, Bombyx mori; however, the expression sites of these Grs remain to be explored. In this study, we used reverse transcription (RT)-PCR to investigate expression of the B. mori Gr-6 (BmGr6) gene, a member of the putative sugar clade gene family in various tissues. BmGr6 is expressed in the midgut, central nervous system (CNS), and oral sensory organs. Moreover, immunohistochemistry using an anti-BmGr6 antiserum demonstrated that BmGr6 is expressed in cells by oral sensory organs, midgut and nervous system. Furthermore, double-immunohistochemistry indicated that BmGr6 is expressed in midgut enteroendocrine cells, also in CNS neurosecretory cells. In particular, a portion of BmGr6-expressing cells, in both midgut and CNS, secretes FMRFamide-related peptides (FaRPs). These results suggest that BmGr6 functions not only as a taste receptor, but also as a chemical sensor such as for the regulation of gut movement, physiological conditions, and feeding behavior of larvae.

    The fungus Rhizoctonia solani is one of the causal agents of numerous diseases that affect crop growth and yield. The aim of this present investigation was to identify a biocontrol agent that acts against R. solani and to determine the agent's protective effect through phytohormones and antioxidant regulation in experimentally infected Chinese cabbage plants. Four rhizospheric soil bacterial isolates GR53, GR169, GR786, and GR320 were tested for their antagonistic activity against R. solani. Among these isolates, GR53 significantly suppressed fungal growth. GR53 was identified as Bacillus amyloliquefaciens subsp. plantarum by phylogenetic analysis of the 16S rDNA sequence. The biocontrol activity of B. amyloliquefaciens subsp. plantarum GR53 was tested in Chinese cabbage plants under controlled conditions. Results showed that R. solani inhibited plant growth (length, width, fresh and dry weight of leaves) by reducing chlorophyll and total phenolic content, as well as by increasing the levels of salicylic acid, jasmonic acid, abscisic acid, and DPPH scavenging activity. By regulating the levels of these compounds, the co-inoculation of B. amyloliquefaciens subsp. plantarum GR53 heightened induced systemic resistance in infected Chinese cabbage, effectively mitigating R. solani-induced damaging effects and improving plant growth. The results obtained from this study suggest that B. amyloliquefaciens subsp. plantarum GR53 is an effective biocontrol agent to prevent the damage caused by R. solani in Chinese cabbage plants.

    The chorion laeve controls the levels of active prostaglandins within the uterus by NAD-dependent 15-hydroxy prostaglandin dehydrogenase (PGDH). The expression of PGDH in chorion is modulated by glucocorticoids and progesterone. In this study, we investigated glucocorticoid receptor (GR) and progesterone receptor A and B (PRA and PRB) in the regulation of PGDH expression in chorion, and we determined whether reduced PGDH expression in chorion during labor is associated with the changes in GR and PR expression by real-time RT-PCR and Western blot analysis. Dexamethasone (DEX) inhibited PGDH expression whereas progesterone stimulated PGDH expression in chorionic trophoblasts. DEX suppressed PGDH expression in GR overexpression and PR knockdown cells. The inhibitory effect of DEX did not occur in GR knockdown cells. Progesterone inhibited PGDH in GR overexpression and PR knockdown cells and it stimulated PGDH in PRB overexpression cells whereas it suppressed PGDH in PRA overexpression cells. Knockdown of c-Jun resulted in a loss of progesterone- and DEX-induced effects. PGDH was down-regulated in chorion tissues during labor. PRB was decreased whereas PRA and GR were increased in chorion during labor. Glucocorticoids inhibit PGDH expression via GR in chorionic trophoblasts. Progesterone enhances PGDH expression through PRB, whereas it inhibits PGDH expression via GR and PRA. Decreased PGDH expression is associated with increased GR and PRA, although decreased PRB, in chorion during labor. Copyright © 2013 American Society for Investigative Pathology.

  6. Ancient founder mutation is responsible for Imerslund-Gräsbeck Syndrome among diverse ethnicities.

    Imerslund-Gräsbeck syndrome (IGS) was described just over 50 years ago by Olga Imerslund and Ralph Gräsbeck and colleagues. IGS is caused by specific malabsorption of cobalamin (Cbl) due to bi-allelic mutations in either the cubilin gene (CUBN) or the human amnionless homolog (AMN). Mutations in the two genes are commonly seen in founder populations or in societies with a high degree of consanguineous marriages. One particular mutation in AMN, c.208-2A>G, causing an out-of-frame loss of exon 4 in the mRNA, is responsible for some 15% of IGS cases globally. We present evidence that this founder mutation causes a substantial percentage of cases among diverse ethnicities and that the mutation is as old as human civilization. Partial genotyping indicated a founder event but its presence in diverse peoples of Arabic, Turkish, Jewish, and Hispanic ancestry suggested that the mutation might be recurrent. We therefore studied the flanking sequence spanning 3.5 Mb to elucidate the origin of the haplotype and estimate the age of the mutation using a Bayesian inference method based on observed linkage disequilibrium. The mutation's distribution, the size of the shared haplotype, and estimates of growth rate and carrier frequency indicated that the mutation was a single prehistoric event. Dating back to the ancient Middle East around 11,600 BC, the mutation predates the advent of writing, farming, and the monotheistic religions of the region. This mutation causes over 50% of the IGS cases among Arabic, Turkish, and Sephardic Jewish families, making it a primary target for genetic screening among diverse IGS cases originating from the Middle East. Thus, rare founder mutations may cause a substantial number of cases, even among diverse ethnicities not usually thought to be related.

    This study is the part of the SAGE project investigating the impact of light absorbing impurities (e.g., aerosols) on the Greenland Ice Sheet (GrIS). Previously ice-core snow samples collected on the GrIS indicated that black carbon (BC) concentrations were significantly enhanced, which could contribute to a decrease in albedo. Along with high levels of BC, the samples also showed significant amounts of ammonia, indicating the BC was sourced from biomass burning - likely from active forest fires in Eurasia and North America in July and August of 2013. In this study, we simulate the transport of potential smoke-filled air parcels using the NASA Langley Trajectory Model (LaTM), running in a backwards mode from selected ice-core sample sites on the GrIS from June 1st to August 31st 2013. The trajectory model is initialized for 24-hour sustained injection from each site, and air parcels are released from the surface to 2 km at 200m intervals. With the trajectory model outputs, we are able to identify trajectories that have coincidences with fires. As a case study, we focus on an event in early August 2013 when episodic enhancements in black carbon deposition are found in snow pit observations. We also utilize Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) data to verify smoke-aerosol signatures in boreal regions based on the NASA LaTM results from late July to early August. We ran backward and forward trajectories from the CALIOP aerosol signatures to verify coincidence with fire events and transport to the GrIS. We found large fires burning west side of the Hudson Bay in late July. CALIOP data captured thick smoke plumes on July 28th over that region and backward/forward trajectories and MODIS Terra/Aqua images support the transport of smoke from these fires to the GrIS.

Ante ella, el proceso dialéctico de exploración, control, selección, retorno…, de la interactividad, ofrece una herramienta aparente para consolidar acciones con cualidades cognitivas, productivas y emocionales. Es evidente que reconocemos el término “interactividad” anclado exclusivamente en el dominio de lo digital. El diseño gráfico, por definición, no es interactivo. Sin embargo, las posibilidades que determinan al medio digital, pueden convertirse en recursos adecuados trasladándolos a la materialidad de los objetos impresos, con el objetivo de activar la mirada del usuario. Este potencial estratégico de vitalización comunicativa, y que de alguna manera podría razonarse como “interactivo”, conjunta las operaciones del objeto gráfico y el usuario. Esto permitiría transformar una posible recepción pasiva de este usuario, meramente espectacular, en una función activa. Como planteaba Pierre Lévy, “estamos pasando de la estética del mensaje a la estética de la interactividad”. ABSTRACT Look, beyond the physiological act of seeing, is a complex construction. Considering this, exploration, control, selection, return and others dialectical processes of interactivity, offer an appropiate tool in order to consolidate actions with cognitive, productive and emotional attributes.It is clear that we recognise ‘interactivity’ term as exclusively clung to the digital control. Graphic design us such, is not interactive. Nevertheless, the sort of possibilities that are determining the digital medium, are able to be turned in suitable resources by translating them to the printing objects nature with the aim of stimulate user’s look.This strategic potential of communicational vitalization, which it could be reasoned as ‘interactive’ in some way, combines graphic object operations with the user’s ones.

  4. Transcriptome analysis of Phelipanche aegyptiaca seed germination mechanisms stimulated by fluridone, TIS108, and GR24.

    Full Text Available P. aegyptiaca is one of the most destructive root parasitic plants worldwide, causing serious damage to many crop species. Under natural conditions P. aegyptiaca seeds must be conditioned and then stimulated by host root exudates before germinating. However, preliminary experiments indicated that TIS108 (a triazole-type inhibitor of strigolactone and fluridone (FL, an inhibitor of carotenoid-biosynthesis both stimulated the germination of P. aegyptiaca seeds without a water preconditioning step (i.e. unconditioned seeds. The objective of this study was to use deep RNA sequencing to learn more about the mechanisms by which TIS108 and FL stimulate the germination of unconditioned P. aegyptiaca seeds. Deep RNA sequencing was performed to compare the mechanisms of germination in the following treatments: (i unconditioned P. aegyptiaca seeds with no other treatment, (ii unconditioned seeds treated with 100 mg/L TIS108, (iii unconditioned seeds treated with 100 mg/L FL + 100 mg/L GA3, (iv conditioned seeds treated with sterile water, and (v conditioned seeds treated with 0.03 mg/L GR24. The de novo assembled transcriptome was used to analyze transcriptional dynamics during seed germination. The key gene categories involved in germination were also identified. The results showed that only 119 differentially expressed genes were identified in the conditioned treatment vs TIS108 treatment. This indicated that the vast majority of conditions for germination were met during the conditioning stage. Abscisic acid (ABA and gibberellic acid (GA played important roles during P. aegyptiaca germination. The common pathway of TIS108, FL+GA3, and GR24 in stimulating P. aegyptiaca germination was the simultaneous reduction in ABA concentrations and increase GA concentrations. These results could potentially aid the identification of more compounds that are capable of stimulating P. aegyptiaca germination. Some potential target sites of TIS108 were also identified in

    2014-01-01

    In this paper, the standard MC approach and BMC are applied to the forging material of the KSNP RPV steel SA508 Gr. 3. A series of fracture toughness tests were conducted in the DBTT transition region, and fracture toughness specimens were extracted from four regions, i.e., the surface, 1/8T, 1/4T and 1/2T. Deterministic material inhomogeneity was reviewed through a conventional MC approach and the random inhomogeneity was evaluated by BMC. In the present paper, four regions, surface, 1/8T, 1/4T and 1/2T, were considered for the fracture toughness specimens of KSNP (Korean Standard Nuclear Plant) SA508 Gr. 3 steel to provide deterministic material inhomogeneity and review the applicability of BMC. T0 determined by a conventional MC has a low value owing to the higher quenching rate at the surface as expected. However, more than about 15% of the KJC values lay above the 95% probability curves indexed with the standard MC T0 at the surface and 1/8T, which implies the existence of inhomogeneity in the material. To review the applicability of the BMC method, the deterministic inhomogeneity owing to the extraction location and quenching rate is treated as random inhomogeneity. Although the lower bound and upper bound curve of the BMC covered more KJC values than that of the conventional MC, there is no significant relationship between the BMC analysis lines and measured KJC values in the higher toughness distribution, and BMC and MC provide almost the same T0 values. Therefore, the standard MC evaluation method for this material is appropriate even though the standard MC has a narrow upper/lower bound curve range from the RPV evaluation point of view. The material is not homogeneous in reality. Such inhomogeneity comes in the effect of material inhomogeneity depending on the specimen location, heat treatment, and whole manufacturing process. The conventional master curve has a limitation to be applied to a large scatted data of fracture toughness such as the weld region

    Full Text Available O objetivo deste trabalho consiste em demonstrar a importância dos gráficos no ensino de geografia para crianças deficientes visuais inseridas no sistema de ensino. Os gráficos estão presentes nos livros didáticos, mas para o invisual é necessário dispor essa forma de representação gráfica de maneira adequada. A cartografia tátil permite gerar gráfico e mapa em alto relevo para a leitura através do sentido tátil. No caso, a pesquisa realizada no desenvolvimento de gráficos táteis para estudantes de 5ª série, valeram-se das teorias de Piaget, que direcionou a avaliação do desenvolvimento cognitivo dos estudantes nas tarefas, e da semiologia gráfica, que ajudou no tratamento gráfico da informação para essa produção. Os resultados apontam que os gráficos construídos instigam tanto à exploração, como favorecem a percepção tátil. É necessário respeitar o “espaço útil” do gráfico, no caso indicado pela distância entre as mãos. Em relação a leitura dos gráficos, as dificuldades detectadas foram quanto à identificação da forma, da noção de escala e do sistema de coordenadas.

    The human glucocorticoid receptor (GR) gene produces C-terminal GRβ and GRα isoforms through alternative use of specific exons 9β and α, respectively. We explored the transcriptional activity of GRβ on endogenous genes by developing HeLa cells stably expressing EGFP-GRβ or EGFP. Microarray analyses revealed that GRβ had intrinsic gene-specific transcriptional activity, regulating mRNA expression of a large number of genes negatively or positively. Majority of GRβ-responsive genes was distinct from those modulated by GRα, while GRβ and GRα mutually modulated each other's transcriptional activity in a subpopulation of genes. We did not observe in HCT116 cells nuclear translocation of GRβ and activation of this receptor by RU 486, a synthetic steroid previously reported to bind GRβ and to induce nuclear translocation. Our results indicate that GRβ has intrinsic, GRα-independent, gene-specific transcriptional activity, in addition to its previously reported dominant negative effect on GRα-induced transactivation of GRE-driven promoters.

    Self-efficacy has been found to have a direct relation with self-care in diabetes. Several tools have been developed and used for evaluating self-efficacy of diabetic patients, the most widely used being the Diabetes Management Self-Efficacy Scale (DMSES). The aim of the present study was to translate, culturally adapt, and validate the Greek DMSES (GR-DMSES) in order for it to be used in the ATTICA pilot study of the SmartCare EU-funded project. Using standard procedures, the original version of DMSES was translated and culturally adapted into Greek. Content validity was assessed by an expert panel with the calculation of a content validity index of the overall scale. Α convenient sample was recruited to complete the questionnaire. Psychometric testing of the produced instrument included internal consistency test (Cronbach's alpha), construct validity (factor analysis), and stability (intraclass correlation coefficient). One hundred and sixteen patients, aged 36-86 years, with type 2 diabetes (T2D) participated in the study. There were no items excluded from the original scale after the content validity procedure. The coefficient Cronbach's alpha for the internal consistency was 0.93 and the intraclass correlation coefficient for the stability with a 5-week time interval was 0.87 (P self-efficacy related to diabetes self-management, thus providing a quick and easy-to-use tool for health professionals dealing with Greek adults with T2D.

    Cold fissure tests are used to determine the proper preheating temperature in order to prevent fissures during the steel welding process. Tekken tests were carried out on a quenched and tempered high resistance 25.4 mm thick steel (ASTM A514 Gr.B) used in structural applications. The welding was carried out using a FCAW semiautomatic process with gas protection and low hydrogen tubular electrode E110T5-K4. Similar parameters and splicing design were later applied in production. The microstructures of the base material and the welding were determined by optic and electron microscopy. The thermal cycles of the welding were recorded in order to relate the preheating temperature with the cooling time from 800 o C - 500 o C (t 8/5 ) and from 800 o C - 100 o C (tg/1) and the presence or not of fissures. Preheating at 150 o C and t 8/5 greater than 17 s was found to guarantee fissure free welding (CW)

    Die IT-Branche hat ihr grünes Gewissen entdeckt. In der jetzigen Verbreitung und Intensität ist dieses Phänomen noch recht neu - lange Zeit schien die Informationstechnik in puncto Umweltverträglichkeit und Energieverbrauch eine "weiße Weste" zu haben. Schließlich läuft ein PC mit Strom und nicht mit - sagen wir mal - einem Dieselmotor: Beim Booten eines Computers schießt nicht erst eine dunkelgraue Rauchwolke aus dem Auspuff, die Lärmerzeugung beschränkt sich auf das Surren des Lüfters, zum Tanken fahren muss man mit ihm auch nicht, und die Produktion der Komponenten erfolgt… ja, wo eigentlich? Irgendwo in der "dritten Welt", in Fernost oder in Mexiko. So sind die umweltschädlichen Aspekte der Produktion von Leiterplatten und sonstigen Bauteilen aus den Augen, aus dem Sinn und bestenfalls sporadisch Gegenstand eines kritischen Greenpeace-Berichts1, der im Überangebot der Medienlandschaft untergeht.

  16. Heat treatment temperature influence on ASTM A890 GR 6A super duplex stainless steel microstructure

    International Nuclear Information System (INIS)

    Martins, Marcelo; Casteletti, Luiz Carlos

    2005-01-01

    Duplex and super duplex stainless steels are ferrous alloys with up to 26% chromium, 8% nickel, 5% molybdenum and 0.3% nitrogen, which are largely used in applications in media containing ions from the halogen family, mainly the chloride ion (Cl - ). The emergence of this material aimed at substituting Copper-Nickel alloys (Cupro-Nickel) that despite presenting good corrosion resistance, has mechanical properties quite inferior to steel properties. The metallurgy of duplex and super duplex stainless steel is complex due to high sensitiveness to sigma phase precipitation that becomes apparent, due to the temperatures they are exposed on cooling from solidification as well as from heat treatment processes. The objective of this study was to verify the influence of heat treating temperatures on the microstructure and hardness of ASTM A890/A890M Gr 6A super duplex stainless steel type. Microstructure control is of extreme importance for castings, as the chemical composition and cooling during solidification inevitably provide conditions for precipitation of sigma phase. Higher hardness in these materials is directly associated to high sigma phase concentration in the microstructure, precipitated in the ferrite/austenite interface. While heat treatment temperature during solution treatment increases, the sigma phase content in the microstructure decreases and consequently, the material hardness diminishes. When the sigma phase was completely dissolved by the heat treatment, the material hardness was influenced only due to ferrite and austenite contents in the microstructure

    The basis of the leak before break (LBB) concept is to demonstrate that piping will leak significantly before a double ended guillotine break (DEGB) occurs. This is demonstrated by quantifying and evaluating the leak process and prescribing safe shutdown of the plant on the basis of the monitored leak rate. The application of LBB for power plant design has reduced plant cost while improving plant integrity. Several evaluations employing LBB analysis on system piping based on DEGB design have been completed. However, the application of LBB on main steam (MS) piping, which is LBB applicable piping, has not been performed due to several uncertainties associated with occurrence of steam hammer and dynamic strain aging (DSA). The objective of this paper is to demonstrate the applicability of the LBB design concept to main steam lines manufactured with SA106 Gr.C carbon steel. Based on the material properties, including fracture toughness and tensile properties obtained from the comprehensive material tests for base and weld metals, a parametric study was performed as described in this paper. The PICEP code was used to determine leak size crack (LSC) and the FLET code was used to perform the stability assessment of MS piping. The effects of material properties obtained from tests were evaluated to determine the LBB applicability for the MS piping. It can be shown from this parametric study that the MS piping has a high possibility of design using LBB analysis.

Considerando-se as fontes, parece mais razoável considerar que os homens que para lá se dirigiram, se casassem com mulheres nativas, realizando, assim, alianças com a população local. As alianças matrimoniais, bastante comuns no mundo grego, tornaram-se, na Magna Grécia, uma política de manutenção e consolidação do poder pelos tiranos da região, e como uma forma bastante eficaz de legitimação da permanência e da descendência dos gregos que chegavam. Esta questão é fundamental, na medida em que desejamos pensar sobre a importância das mulheres na formação da identidade do grupo e na legitimação política e social dos gregos que se estabeleceram no sul da Itália.

    In 1974, at the Medical Policlinic of the University of Zürich, German-born physician-scientist Andreas Grüntzig (1939–1985) for the first time applied a balloon-tipped catheter to re-open a severely stenosed femoral artery, a procedure, which he initially called “percutaneous transluminal dilatation”. Balloon angioplasty as a therapy of atherosclerotic vascular disease, for which Grüntzig and Charles T. Dotter (1920–1985) received a nomination for the Nobel Prize in Physiology or Medicine in 1978, became one of the most successful examples of translational medicine in the twentieth century. Known today as percutaneous transluminal angioplasty (PTA) in peripheral arteries or percutaneous transluminal coronary angioplasty (PTCA) or percutaneous coronary intervention (PCI) in coronary arteries, balloon angioplasty has become the method of choice to treat patients with acute myocardial infarction or occluded leg arteries. On the occasion of the 40th anniversary of balloon angioplasty, we summarize Grüntzig’s life and career in Germany, Switzerland, and the United States and also review the developments in vascular medicine from the 1890s to the 1980s, including Dotter’s first accidental angioplasty in 1963. The work of pioneers of catheterization, including Pedro L. Fariñas in Cuba, André F. Cournand in France, Werner Forssmann, Werner Porstmann and Eberhard Zeitler in Germany, António Egas Moniz and Reynaldo dos Santos in Portugal, Sven-Ivar Seldinger in Sweden, and Barney Brooks, Thomas J. Fogarty, Melvin P. Judkins, Richard K. Myler, Dickinson W. Richards, and F. Mason Sones in the United States, is discussed. We also present quotes by Grüntzig and excerpts from his unfinished autobiography, statements of Grüntzig’s former colleagues and contemporary witnesses, and have included hitherto unpublished historic photographs and links to archive recordings and historic materials. This year, on June 25, 2014, Andreas Grüntzig would have celebrated

Each one of the classifiers recorded the occurrence of green-coated, brown and black beans before and after removal of the silver skin. The data revealed that more than half of the beans had normal green color whereas 44.9 per cent were green-coated, 3.5 per cent were brown and 0.1 per cent were black beans. The removal of the silver skin affected the previous classification giving 59.7 per cent of normal green beans, 39.5 per cent of brown and 0.3 per cent of black beans. These observations indicated that the so-called green-coated beans are caused by the presence of the silver skin which retains green pigments probably chlorophyll.

    SA508Gr4 is a newly developed high-strength steel for nuclear reactor pressure vessels. Its welding characteristics remain largely unexplored. In this work, the simulated heat affected zone continuous cooling transformation (SH-CCT) diagram of SA508Gr4 steel was constructed and the high-temperature cooling phase compositions and the properties of the heat affected zone (HAZ) were characterized using dilatometry and microscopic tests. The results show that the phase transformation in the HAZ was divided into bainite and martensite transformation stages. When 4.6 ≤ t{sub 8/5} (the HAZ cooling time from 800 C to 500 C) ≤ 15 s, lath-shaped martensite was fully developed, resulting in extensive hardening and cold cracking in the HAZ, while the cooling time required to form the bainite completely exceeds 1 200 s. Thus, to improve weld quality, preheating to 196 C or higher is recommended.

    SA508Gr4 is a newly developed high-strength steel for nuclear reactor pressure vessels. Its welding characteristics remain largely unexplored. In this work, the simulated heat affected zone continuous cooling transformation (SH-CCT) diagram of SA508Gr4 steel was constructed and the high-temperature cooling phase compositions and the properties of the heat affected zone (HAZ) were characterized using dilatometry and microscopic tests. The results show that the phase transformation in the HAZ was divided into bainite and martensite transformation stages. When 4.6 ≤ t 8/5 (the HAZ cooling time from 800 C to 500 C) ≤ 15 s, lath-shaped martensite was fully developed, resulting in extensive hardening and cold cracking in the HAZ, while the cooling time required to form the bainite completely exceeds 1 200 s. Thus, to improve weld quality, preheating to 196 C or higher is recommended.

    Full Text Available Artiklen handler om undervisning i skolen, om børn og lærere, som er optaget af at arbejde med faget der i Grønland kaldes ”Lokale valg”. Faget indeholder fire fagområder ”Kunst og arkitektur”, ”Idræt og udeliv”, ”Musik, sang, bevægelse og drama” og ”Håndværk og design”.Vi har valgt at rette vore blikke på, hvordan undervisningen bidrager til, at give elever og lærere fælles gode faglige og personlige oplevelser. Især har vi rettet fokus på de gode historier, læreren fortæller. Det er fortællinger om givende undervisning - set i et lærerperspektiv. Vores sigte er, at rette et pædagogisk blik på de gode historier som læreren oplever dem og de læringsmæssige udfordringer, der knytter sig til undervisningen i fagområdet ”Lokale valg”. Vi ønsker at bidrage til, at studerende får et nuanceret billede af, hvad der foregår i skolen, så disse indtryk kan medvirke til faglig refleksion.

    Full Text Available Assinaturas são os grafismos mais efetuados pelas pessoas, por demonstrar conhecimento e concordância a documentos diversos. O exame grafoscópico de assinaturas disfarçadas é uma das determinações mais difíceis de proceder na Documentoscopia. Os disfarces podem confundir os peritos e conduzir a erros quanto à autoria de assinaturas. O objetivo deste trabalho foi identificar as características mais frequentes encontradas em análises grafoscópicas de assinaturas disfarçadas. Foi solicitado a 102 voluntários que assinassem sua assinatura habitual por cinco vezes e, então, que tentassem disfarçar sua assinatura. Posteriormente, realizou-se o confronto gráfico entre as assinaturas padrão e as disfarçadas, e as alterações encontradas foram anotadas, sendo que as mais frequentes foram: modificações da forma de letras maiúsculas e minúsculas, de dimensão e calibre, na forma e na posição de ataques e remates, na quantidade de levantamentos da caneta durante a escrita (andamento gráfico e a alteração ou supressão de símbolos ou caracteres especiais. Esses dados podem ajudar os peritos a identificar características gráficas indicativas de disfarces, quando da verificação de autenticidade. Por outro lado, observou-se que características alteradas com menor frequência surgem em assinaturas disfarçadas e podem levar a uma conclusão errônea no sentido da falsificação do lançamento gráfico.

    Full Text Available In the petroleum industry, the biphasic conditions in storage and separation tanks allow that the material to remain exposed to two different environments, causing its deterioration. In this article, an evaluation is made of the corrosive behavior and Vickers microhardness (HV of two high strength low alloy (HSLA steels and how their surfaces are characterized. The ASTM 572 Gr50 steel showed a lower corrosion rate in all systems after being immersed for 720 and 1440 hours. Characterizing the surface by means of Scanning Electron Microscopy (SEM showed uniform and localized corrosion for the both steels, and revealed that the ASTM 572 Gr50 steel shows pitting corrosion in crude oil systems. The electrochemical results revealed that the corrosion potential of API X60 steel was more negative; however the ASTM 572 Gr50 steel had a higher current density and a lower polarization resistance when immersed in an oil/seawater mixture. It also observed that, after being immersed in the corrosive fluids, the microstructures of the steels were not modified and variations in their microhardness (HV were minute.

  2. Quantitative photoacoustic integrating sphere (QPAIS platform for absorption coefficient and Grüneisen parameter measurements: Demonstration with human blood

    Directory of Open Access Journals (Sweden)

    Yolanda Villanueva-Palero

    2017-06-01

    Full Text Available Quantitative photoacoustic imaging in biomedicine relies on accurate measurements of relevant material properties of target absorbers. Here, we present a method for simultaneous measurements of the absorption coefficient and Grüneisen parameter of small volume of liquid scattering and absorbing media using a coupled-integrating sphere system which we refer to as quantitative photoacoustic integrating sphere (QPAIS platform. The derived equations do not require absolute magnitudes of optical energy and pressure values, only calibration of the setup using aqueous ink dilutions is necessary. As a demonstration, measurements with blood samples from various human donors are done at room and body temperatures using an incubator. Measured absorption coefficient values are consistent with known oxygen saturation dependence of blood absorption at 750 nm, whereas measured Grüneisen parameter values indicate variability among five different donors. An increasing Grüneisen parameter value with both hematocrit and temperature is observed. These observations are consistent with those reported in literature.

    Based on Grüneisen's theory, the elastic properties and thermal expansion of bulk SnSe with the Pnma phase are investigated by using first-principles calculations. Our numerical results indicate that the linear thermal expansion coefficient along the a direction is smaller than the one along the b direction, while the one along the c direction shows a significant negative value, even at high temperature. The numerical results are in good accordance with experimental results. In addition, generalized and macroscopic Grüneisen parameters are also presented. It is also found that SnSe possesses negative Possion's ratio. The contributions of different phonon modes to NTE along the c direction are investigated, and it is found that the two modes which make the most important contributions to NTE are transverse vibrations perpendicular to the c direction. Finally, we analyze the relation of elastic constants to negative thermal expansion, and demonstrate that negative thermal expansion can also occur even with all positive macroscopic Grüneisen parameters.

    Full Text Available Teniendo en cuenta que la prensa gráfica decimonónica se caracterizó por su dependencia de los agrupamientos políticos y que las publicaciones, puestas al servicio de las diferentes facciones, son una muestra de aquella tensión finisecular, nos proponemos analizar la relación entre lo político y lo periodístico en la prensa gráfica humorística de finales del siglo XIX en Rosario, Argentina. En este trabajo tendremos en cuenta algunos ejemplos significativos de aquel desarrollo, con especial hincapié en el rol de las revistas “La Cabrionera” y “Caramelo” en la coyuntura electoral de 1890. Ambas son ubicadas dentro del género prensa gráfica satírico-política y ofrecen un anclaje histórico preciso, signado por el proceso de cambio entre una prensa de cuño estrictamente militante y otra que adelanta algunas prácticas discursivas de la prensa generalista y comercial del siglo XX. En tal sentido, nos proponemos analizar el modo en que cada revista despliega estrategias de intervención eminentemente políticas.

    Full Text Available A finalidade do armazenamento do grão de pólen é conservar material para futura utilização, proporcionando-lhe condições ótimas, de forma a manter seu poder germinativo, vigor e integridade genética originais. O objetivo deste trabalho foi verificar o poder germinativo dos grãos de pólen de mamoneira (Ricinus communis L., após armazenamento a baixas temperaturas. Para tanto, grãos de pólen dos cultivares IAC 80 e AL Guarany 2002 foram utilizados e armazenados em quatro temperaturas: -196, -72, -18 e 4 ºC, durante um período de oito semanas. A avaliação da viabilidade deste pólen foi realizada semanalmente, até completar cinco semanas, sendo realizada uma última avaliação após a oitava semana de armazenamento, por meio do teste de germinação in vitro. Meio de cultura, contendo 10 gL-1 de ágar, 100 gL-1 de sacarose, 0,004 gL-1 de ácido bórico e pH 6,0, foi preparado e depositado em placas de lâmina escavada, onde o pólen foi distribuído sobre a superfície do meio. As placas foram incubadas a 20 ºC em BOD. O delineamento experimental foi inteiramente casualizado, em arranjo fatorial 2 x 4 (2 cultivares x 4 temperaturas para cada tempo de armazenamento, sendo analisados 100 grãos de pólen por repetição, totalizando seis de cada tratamento. Verificou-se diferença significativa entre os tratamentos para a interação cultivar x temperatura na quinta semana de observação (p < 0,05. Demais interações foram altamente significativas em todas as épocas de observação (p < 0,01. Portanto, a utilização de ultrabaixas temperaturas permite a manutenção da viabilidade de grãos de pólen de mamoneira, até a quinta semana de armazenamento.

    2015-08-01

    Full Text Available ResumoO artigo apresenta o impacto populacional provocado pela epidemia de sarampo (1748-1750 na capitania do Grão-Pará e sua relação com o processo de inserção da mão de obra escrava africana. A análise é fundamentada na documentação produzida no século XVIII, levantada em diferentes arquivos brasileiros e portugueses, incluindo correspondências oficiais, crônicas, memórias, mapas populacionais e listagens de mortos pela epidemia. A documentação serial foi posta em base de dados, construída a partir das 80 listagens de mortos pelo sarampo, o que permitiu uma análise do impacto demográfico da epidemia. Concomitantemente, a contagem populacional das vilas e povoações da capitania, do terceiro quartel do século XVIII, compôs uma segunda base de dados e auxiliou na compreensão da distribuição interna de escravos africanos. O ponto de interseção entre as bases de dados é formado pelo conjunto da documentação histórica administrativa, que trata dos efeitos da epidemia e das possibilidades de solução da crise de mão de obra - ocasionada pela alta mortalidade de indígenas. O estudo procura mostrar não apenas a mortalidade causada pelo sarampo, mas também a construção de uma política para a inserção de escravos africanos na região. Para tanto abordam-se a epidemia em Belém, a importância do trabalho indígena para os colonos, o número de mortos e a distribuição da mortalidade considerando espaço e sazonalidade (meses e anos. Também se discutem a luta entre projetos para sanar a demanda de mão de obra, gerada pela alta mortalidade do sarampo, e a política de inserção de escravos africanos para combater a carência de trabalhadores, bem como a distribuição desses escravos na capitania.

    Full Text Available The author of this text gave lessons of graphic humour and comics dealing with local customs, in the classrooms at the Círculo de Bellas Artes in Madrid during a week in the 2010 summer. His report about these days shows a way to consider the teaching of the comic that places the information about the media and its own narrative tools in close-up and then, the mere plastic accuracy. This way of teaching also proposes specific exercises and alternation of new and traditional technologies. Giving the creative historical precedents and the sector publishing reality, is also a matter of importance from a professional point of view. At the same time, the author explains his theory on the humouristic speech, some considerations about the nature of the drawing and championed a very large definition of the two words: “cartoon story”.

    El autor de este texto impartió un taller de humor gráfico e historieta costumbrista en las aulas del madrileño Círculo de Bellas Artes durante una semana del verano de 2010. Su relato de aquellos días esboza una forma de abordar la enseñanza de la historieta que coloca en primer término el conocimiento del medio y sus herramientas narrativas sobre la mera habilidad plástica. En esa dirección, propone ejercicios concretos y procedimientos que alternan nuevas y tradicionales tecnologías. También destaca la importancia formativa de dar a conocer los antecedentes creativos históricos del medio y la realidad editorial del sector desde el punto de vista profesional, al mismo tiempo que expone fugazmente su particular teoría sobre la estructura del discurso humorístico, emite diversas consideraciones sobre la naturaleza del dibujo y aboga por una amplísima definición del término historieta.

    Full Text Available La sociologie grecque a été liée aux évolutions sociopolitiques et idéologiques du xxe siècle en Grèce. Dans le système politique, la sociologie a fonctionné comme point de repère légitimateur, comme paradigme et comme élément de modernisation. En même temps, les courants radicaux de gauche mais aussi de droite ont conçu la sociologie comme instrument de réforme sociale. Des revues importantes, tout au long du xxe siècle, ont prôné des idées radicales se basant sur la théorie sociologique. Après la 2ème Guerre Mondiale, l’État a organisé la recherche sociologique sur une base plus moderne et systématique, avec l’appui de la communauté sociologique occidentale. En même temps, la sociologie a été introduite dans les universités. Curieusement, les plus importants sociologues grecs du xxe siècle (parmi lesquels Nicos Poulantzas, Nicos Mouzélis, et avant eux Dimosthènes Danielidis, Avrotélis Eleftheropoulos et Constantinos Karavidas ont fait leur carrière à l’étranger ou sont resté à la marge des institutions étatiques et académiques grecques, ce qui peut s’explique par le fait que leurs idées conduisaient à la restructuration totale du système sociopolitique d’un pays en état de dépendance géopolitique et économique, comme était la Grèce au xxe siècle.Some Aspects of History of Sociology in Greece (1900-1980Sociology in contemporary Greece has had strong ties with the social, political and ideological evolutions.

    2006-12-01

    Full Text Available In many reservoir engineering and tectonic problems, the ability to predict both the occurrence and extent of inelastic deformation and failure hinges upon a fundamental understanding of the phenomenology and micromechanics of compaction in reservoir rock. This paper reviews recent research advances on mechanical compaction of porous sandstone, with focus on the synthesis of laboratory data, quantitative microstructural characterization of damage, and theoretical models based on elastic contact and fracture mechanics. The mechanical attributes of compaction in nominally dry and saturated samples have been studied under hydrostatic and nonhydrostatic loadings over a broad range of pressure conditions. Specific topics reviewed herein include: comparison of mechanical and acoustic emission data with continuum plasticity theory; microstructural control of onset and development of compaction; strain hardening and spatial evolution of damage during compaction; and the weakening effect of water on compactive yield and porosity change. Pour de nombreux problèmes de tectonique et d'ingénierie de réservoir, la capacité à prévoir à la fois la fréquence, l'ampleur de la déformation inélastique et les ruptures repose sur une compréhension fondamentale de la phénoménologie et de la micromécanique de compaction dans les roches-réservoirs. Cet article présente les résultats de recherches récentes sur la compaction mécanique des grès poreux. On insiste plus particulièrement sur la synthèse des données de laboratoire, la caractérisation microstructurale quantitative de l'endommagement, ainsi que sur les modèles théoriques basés sur un contact élastique et sur la mécanique de la rupture. Les attributs mécaniques de la compaction sur des échantillons initialement secs et saturés ont été étudiés sous des chargements hydrostatiques et non hydrostatiques dans une large gamme de pression.

    The task of designing a digital fluid power displacement unit entails a choice of topology. Consequently, this choice entails a need for knowledge of the various applicable topologies to choose from. In this paper a morphological topology generation approach is used to derive a series of radial...... piston topologies. The morphological approach is combined with the Chebychev- Grübler-Kutzbach criterion, a fully rotatable shaft condition and a straight line path generation condition in order to obtain one degree of freedom single closed chain mechanisms applicable for wind turbines and wave energy...

    Amidos e seus derivados são utilizados como carregadores em processos de secagem de produtos por atomização onde a densidade aparente é característica importante e deve ser controlada nos produtos desidratados de uso farmacêutico. No Brasil os amidos comerciais são originários de milho e mandioca, mas existem outros com potencial para extração. Os amidos de biri e taro foram selecionados por representarem extremos de tamanho de grânulos e assim verificar o efeito do tamanho sobre a densidade aparente de produtos desidratados por atomização. Foram usados para comparação os amidos comerciais de mandioca e milho, por serem de uso comum em produtos atomizados e apresentarem tamanhos intermediários de grânulos. A atomização foi feita em Spray Dryer Lab Plant SD 04, operando sob pressão de 6 lb/in2, fluxo 7,6 mL/mim, e bico 1 cm. A temperatura de entrada foi fixada em 200ºC mas este modelo de equipamento não permite regular a temperatura de saída. Os produtos atomizados tiveram extrato de boldo como base, usando os quatro amidos como suporte. O produto seco foi avaliado quanto à umidade, atividade de água, tamanho das partículas e densidade aparente. Os resultados mostraram que o tamanho das partículas, e por decorrência do tamanho dos grânulos de amido, têm influência sobre a densidade aparente do produto final, que foi maior (694, 27 g/mL para o amido de biri e menor (456,13 g/mL para amido de taro. Os amidos de milho e mandioca proporcionaram valores muito próximos e intermediários, de 521, 51 e 581, 48 g/mL, que representam também o padrão de variação de tamanho dos grânulos. Palavras-chave: atomização; densidade aparente; granulometria; amidos.

    Full Text Available Neste artigo é proposto, para o monitoramento de processos normais bivariados, um gráfico de controle baseado nas variâncias amostrais de duas características de qualidade. Os pontos plotados no gráfico correspondem ao valor da maior variância amostral. O gráfico proposto, denominado gráfico de VMAX, tem um desempenho superior ao do gráfico da variância amostral generalizada |S| e, além disso, tem uma melhor capacidade de diagnóstico, ou seja, com ele é mais fácil identificar a variável que teve sua variabilidade alterada pela ocorrência da causa especial. Quando a amostragem dupla está em uso o gráfico proposto também tem um desempenho superior ao do gráfico de |S|, exceto em alguns casos em que o tamanho da segunda amostra é muito grande.In this paper a control chart based on sample variances from two quality characteristics for monitoring bivariate normal processes is proposed. The points plotted on the chart are the maximum of the values of these two statistics. The proposed chart (VMAX chart detects process disturbances faster than the generalized variance |S| chart and has a better diagnostic feature, that is, with the VMAX chart it is easier to relate an out-of-control signal to the variable whose variability has moved away from its in-control state. When the double sampling scheme is used the proposed chart has also a better performance, except in a few cases in which the size of the samples at the second stage is very large.

    Full Text Available Typically, probiotics are consumed in dairy based products such as yogurt. However, given the rise in various diet types, non-dairy alternatives have been developed, such as inoculating fruit juices with probiotics. Lactobacillus rhamnosus GR-1 is a probiotic strain exerting a number of human health benefits such as the prevention of urinary tract infections. Therefore, the objective of this study was to determine the viability of L. rhamnosus GR-1 in apple cider, orange, and grape juice when fortified with either 4% short chain or 4% long chain inulin fiber over 72 h of fermentation and 30 days of refrigerated storage. The secondary objective was to determine consumer acceptability of apple cider and orange juice samples using the hedonic scale. All of the fruit juice samples achieved a mean viable count of at least 107 CFU/mL during 72 h of fermentation and 30 days of refrigerated storage. According to the sensory evaluation, which evaluated samples according to appearance, flavor, texture, and overall acceptability, apple cider juice with long chain inulin fiber proved to have the highest score for all characteristics except appearance. Therefore, this study indicated a potential for probiotic fruit juices as a valid alternative to dairy based probiotic products.

    Cobalamin malabsorption accompanied by selective proteinuria is an autosomal recessive disorder known as Imerslund-Gräsbeck syndrome in humans and was previously described in dogs due to amnionless (AMN) mutations. The resultant vitamin B12 deficiency causes dyshematopoiesis, lethargy, failure to thrive, and life-threatening metabolic disruption in the juvenile period. We studied 3 kindreds of border collies with cobalamin malabsorption and mapped the disease locus in affected dogs to a 2.9Mb region of homozygosity on canine chromosome 2. The region included CUBN, the locus encoding cubilin, a peripheral membrane protein that in concert with AMN forms the functional intrinsic factor-cobalamin receptor expressed in ileum and a multi-ligand receptor in renal proximal tubules. Cobalamin malabsorption and proteinuria comprising CUBN ligands were demonstrated by radiolabeled cobalamin uptake studies and SDS-PAGE, respectively. CUBN mRNA and protein expression were reduced ~10 fold and ~20 fold, respectively, in both ileum and kidney of affected dogs. DNA sequencing demonstrated a single base deletion in exon 53 predicting a translational frameshift and early termination codon likely triggering nonsense mediated mRNA decay. The mutant allele segregated with the disease in the border collie kindred. The border collie disorder indicates that a CUBN mutation far C-terminal from the intrinsic factor-cobalamin binding site can abrogate receptor expression and cause Imerslund-Gräsbeck syndrome.

    Dissimilar metal weldment (DMW) is frequently used for joining low-alloy steel pressure vessel nozzles and steam generator nozzles to nickel-based wrought alloy or austenitic stainless steel components in high energy systems. This feature also significantly hinders C diffusion from the ferrite base metal to the weld metal. Until now, stress corrosion cracking has not occurred in DMWs where a High-Cr weld metal (such as Alloy 152 or Alloy 690), which is Ni-base weld metal including relative high Cr, is used as the weld metal in the weld between the nickel-based alloy and low-alloy steel. To understand the microstructure and corrosion evolution on fusion boundary between low-alloy steel and Ni-base weld metal, microstructural analysis and polarization test were performed with A533 Gr. B/Alloy 152/Alloy 690. Remarkable changes were observed in corrosion resistance and hardness at fusion boundary between low-alloy steel and Ni-base weld metal. The precipitate, which has different potential with peripheral region, can cause galvanic corrosion or pitting corrosion and is the one of hardening methods by disturbing movement of the dislocation. At initial step of heat treatment, the number of precipitates was increased. In fusion boundary between A533 Gr. B and Alloy 152, the corrosion resistance was decreased, and the hardness was increased. Next, at further step, the number of precipitates.

    The Upper Cretaceous Djadokhta Formation has been intensively surveyed for its fossil vertebrate fauna for nearly a century. Amongst other theropods, dromaeosaurids and parvicursorines are common in the formation, but ornithomimosaurs are extremely rare. A new ornithomimosaur material was discovered from the Djadokhta Formation, represented by eolian deposits, of the Tögrögiin Shiree locality, Mongolia. This is only the third ornithomimosaur specimen reported from this formation, and includes the astragalus, the calcaneum, the third distal tarsal, and a complete pes. The new material is clearly belonged to Ornithomimidae by its arctometatarsalian foot condition and has the following unique characters; unevenly developed pair of concavities of the third distal tarsal, curved contacts between the proximal ends of second and fourth metatarsals, the elongate fourth digit, and a laterally inclined medial condyle on phalanx IV-1. These diagnostic characters of the Djadokhtan ornithomimosaur indicate that this is a new taxon. Our phylogenetic analysis supports three clades within derived ornithomimosaurs, and the new taxon is placed a member of the derived ornithomimosaurs. The present specimen is the first ornithomimid record from eolian Tögrögiin Shiree locality, and is indicative of their capability to adapt to arid environments.

    Allergies are mainly characterized as an unrestrained Th2-biased immune response. Epidemiological data associate protection from allergic diseases with the exposure to certain infectious agents during early stages of life. Modulation of the immune response by pathogens has been considered to be a major factor influencing this protection. Recent evidence indicates that immunoregulatory mechanisms induced upon infection ameliorate allergic disorders. A longitudinal study has demonstrated reduced frequency and incidence of asthma in children who reported a prior infection with Salmonella. Experimental studies involving Salmonella enterica serovar Typhimurium-infected murine models have confirmed protection from induced allergic airway inflammation; however, the underlying cause leading to this amelioration remains incompletely defined. In this study, we aimed to delineate the regulatory function of Salmonella Typhimurium infection in the amelioration of allergic airway inflammation in mice. We observed a significant increase in CD11b+ Gr1+ myeloid cell populations in mice after infection with S. Typhimurium. Using in vitro and in vivo studies, we confirmed that these myeloid cells reduce airway inflammation by influencing Th2 cells. Further characterization showed that the CD11b+ Gr1+ myeloid cells exhibited their inhibitory effect by altering GATA-3 expression and interleukin-4 (IL-4) production by Th2 cells. These results indicate that the expansion of myeloid cells upon S. Typhimurium infection could potentially play a significant role in curtailing allergic airway inflammation. These findings signify the contribution of myeloid cells in preventing Th2-mediated diseases and suggest their possible application as therapeutics.

    Full Text Available Gráficos de controle baseado nos resíduos de Poisson têm sido têm sido úteis para monitorar o número de não conformidade em um processo industrial. O modelo de regressão de Poisson é o mais popular dos modelos lineares generalizados, o qual é usado para modelar dados de contagem. O modelo de regressão de Poisson tem uma suposição de que a variância é igual á media, mas nem sempre isso acontece, em muitas situações tem-se encontrado que a variância é maior do que a média, e este fenômeno é denominado como superdispersão. Os dados usados nesse estudo são números de não conformidades da seção de tecelagem da Indústria Têxtil Oeste Ltda. Observou-se que esses dados têm uma grande variabilidade e possuem superdispersão. Assim, foi preciso aplicar os modelos de Regressão Poisson antes da utilização das técnicas dos gráficos de controle.

    Integrated approaches for pharmacology are required for the mechanism-based predictions of adverse drug reactions that manifest due to concomitant intake of multiple drugs. These approaches require the integration and analysis of biomedical data and knowledge from multiple, heterogeneous sources with varying schemas, entity notations, and formats. To tackle these integrative challenges, the Semantic Web community has published and linked several datasets in the Life Sciences Linked Open Data (LSLOD) cloud using established W3C standards. We present the PhLeGrA platform for Linked Graph Analytics in Pharmacology in this paper. Through query federation, we integrate four sources from the LSLOD cloud and extract a drug-reaction network, composed of distinct entities. We represent this graph as a hidden conditional random field (HCRF), a discriminative latent variable model that is used for structured output predictions. We calculate the underlying probability distributions in the drug-reaction HCRF using the datasets from the U.S. Food and Drug Administration's Adverse Event Reporting System. We predict the occurrence of 146 adverse reactions due to multiple drug intake with an AUROC statistic greater than 0.75. The PhLeGrA platform can be extended to incorporate other sources published using Semantic Web technologies, as well as to discover other types of pharmacological associations.

Ressaltam, no ponto de vista doutrinário, os diversos fatores que podem interferir na ocorrência dêsses infortúnios de trabalho; e, mostrando como tem sido superestimada a culpabilidade das máquinas, realçam a importância dos fatores individuais — idade e experiência do operário, doenças e defeitos físicos, atitude mental, constituição fisio-psicologica. Salientam como a evidência da predisposição a acidentes, que se reconheça existir, possibilita manter os operários, já em função ou pretendentes a emprego, debaixo de supervisão rigorosa; e oportuniza mesmo colocá-los melhormente, em tarefas que, no máximo, só lhes possam acarretar aciden¬tes de natureza leve. Mostram que, no período em estudo — 1942 a 1945, houve ao todo 1.123 acidentes na I.N., com o coeficiente geral de incidência de 220.3 por 1.000 operários expostos. O coeficiente de acidentes médios ou graves foi de 32 por mil, no mesmo período. Apontando ainda a descenção, no quatriênio, das curvas relativas tanto aos acidentes totais, como aos médios ou graves e aos produzidos por máquinas, dão a ver que a taxa, que retrata essa descida, é, para os primeiros, 3.5 e cêrca de 10 vêzes maior, respectivamente, que a dos acidentes por máquinas e dos médios ou graves.

As primíparas faziam acompanhamento pré-natal em um hospital pertencente a uma universidade paulistana, tendo nível de escolaridade de segundo grau completo à terceiro grau incompleto e suas gestações, inicialmente, classificadas como de baixo risco do ponto de vista obstétrico. A coleta de dados associou entrevistas individuais semi-dirigidas à aplicação do Desenho da Figura Humana, segundo a técnica de Machover. A primeira coleta, feita no hospital em 2001, compreendeu mais de um contato com cada mulher e a segunda se deu em um único encontro, nas respectivas residências das mesmas. Utilizando o referencial psicanalítico, a análise qualitativa do material, apontou, em dois casos, para um amadurecimento da relação mãe/filho. No terceiro, configurou-se uma relação mãe/filho conturbada. A despeito da limitação do estudo, em função do pequeno número de mulheres acompanhadas, foram consideradas possibilidades de intervenções, por meio da escuta diferenciada, em um espaço em que pudessem falar de suas angústias, temores, expectativas e desejos e a utilização do DFH como objeto intermediador. Tal espaço pode ser dirigido tanto às mulheres como às equipes multiprofissionais visando favorecer a relação mãe/pai/criança, e estimular o desenvolvimento, o mais saudável possível, da criança. Pensa-se assim poder ampliar as chances de um trabalho interventivo reduzir o agravamento de futuros problemas.

    Grizzled (gr) is a recessive mouse mutation resulting in a gray coat color and reduced perinatal viability. Mocha (mh) is one of several recessive mouse mutants characterized by platelet storage pool disorder, pigment abnormalities, reduced fertility, kidney function deficiencies, and, in some mutants, inner ear and natural killer cell deficiencies. Murine platelet storage pool deficient mutants may be models for Chediak-Higashi and Hermansky-Pudlak syndromes in humans. The genes for gr and mh are very closely linked to each other (0 {+-} 1.2 cM). However, their relative position with respect to molecular markers was previously unknown. Thus, genetic mapping of the gr locus will also yield information about the mh location. To map these two genes genetically, we have performed an intersubspecific backcross of grizzled mice with Mus musculus castaneus. In 539 progeny tested, we found no recombination between the gr gene, the gene for anti-Muellerian hormone (Amh), and the microsatellite markers D10Mit7, D10Mit21, and D10Mit23. One recombination event for each of the flanking markers Basigin (Bsg) and D10Mit22 was identified. These closely linked markers should provide entry points for positional cloning of the gr and mh genes. The region linked to grizzled is homologous to a gene-rich region on human Chromosome 19p13.3.

In the K14E7 mouse model, the morphology of Langerhans cells and the migratory activity of dendritic cells were abnormal. An increase in CD11b+Gr1+ cells was observed in the blood and skin of K14E7 mice, and molecules related to CD11b+Gr1+ chemoattraction (MCP1 and S100A9 were upregulated. Conclusions. These data suggest that the HPV16 E7 oncoprotein impairs the function and morphology of DCs and induces the systemic accumulation of CD11b+Gr1+ cells.

    Lactobacillus rhamnosus GR-1 and L. fermentum RC-14 are well-characterized probiotic strains with efficacy in the prevention and treatment of urogenital infections in women. The aim of the present study was to apply a molecular biology-based methodology for the detection of these strains and L. rhamnosus GG (a commercially available intestinal probiotic) in the human vagina in order to assess probiotic persistence at this site. Ten healthy women inserted vaginally a capsule containing either a combination of strains GR-1 and RC-14 or the GG strain for 3 consecutive nights. Vaginal swabs taken before and at various time points after probiotic insertion were analyzed, and the Lactobacillus flora was assessed by randomly amplified polymorphic DNA (RAPD) analysis. This method generated discrete DNA fingerprints for GR-1, RC-14, and GG and enabled successful detection of these strains in the vagina. Strain GR-1 and/or strain RC-14 was found to persist in the vaginal tract for up to 19 days after vaginal instillation, while L. rhamnosus GG was detectable for up to 5 days postadministration. In conclusion, the fates of probiotic L. rhamnosus and L. fermentum strains were successfully monitored in the human vagina by RAPD analysis. This technique provides molecular biology-based evidence that RC-14 and GR-1, strains selected as urogenital probiotics, persist in the human vagina and may be more suited to vaginal colonization than L. rhamnosus GG. This highlights the importance of proper selection of strains for urogenital probiotic applications. PMID:11777835

    Extrinsic control of single neurons and neuronal populations is a powerful approach for understanding how neural circuits function. Adding new thermogenetic tools to existing optogenetic and other forms of intervention will increase the complexity of questions that can be addressed. A good candidate for developing new thermogenetic tools is the Drosophila gustatory receptor family, which has been implicated in high-temperature avoidance behavior. We examined the five members of the Gr28b gene cluster for temperature-dependent properties via three approaches: biophysical characterization in Xenopus oocytes, functional calcium imaging in Drosophila motor neurons, and behavioral assays in adult Drosophila. Our results show that Gr28bD expression in Xenopus oocytes produces a non-specific cationic current that is activated by elevated temperatures. This current is non-inactivating and non-voltage dependent. When expressed in Drosophila motor neurons, Gr28bD can be used to change the firing pattern of individual cells in a temperature-dependent fashion. Finally, we show that pan-neuronal or motor neuron expression of Gr28bD can be used to alter fruit fly behavior with elevated temperatures. Together, these results validate the potential of the Gr28bD gene as a founding member of a new class of thermogenetic tools.

    Phenomena responsible of partially premixed laminar flame stabilisation are investigated on a rich premixed burner configuration. The structure and aerodynamic of the flame generated by a cooking model burner are characterized by Planar Laser Induced Fluorescence of OH radical and Particle Image Velocimetry. The flame behaviour is studied from a stable reference case toward blow-out by varying the flow inlet conditions, the burner geometry and its thermal properties. The flame can be considered as two neighbour and independent reactive zones, each consisting of a double edge flame. The upper double flame stabilisation is similar to the one of a Bunsen burner with a flame-holder attached base and a flame tip stabilized in the flow according to the ratio of the flow velocity and flame speed of the rich pre-mixture. The bottom double flame is stabilized at the crossing point of the stoichiometric flame speed. The flame is finally blown out when there is no more crossing point. (author)

    This article presents an overview on low-cost techniques for flame diagnostics, especially the measurement of excess air. This parameter is useful for monitoring and controlling flames in both the domestic and industrial area. The classical sensors for oxygen like the Lambda probe and the wet chemical cells are based on electrochemical concentration cells. The measurement of carbon monoxide may also be used and a number of sensors are available (e.g. wet chemical cells, thin film sensors based on ZrO{sub 2} or Ga{sub 2}O{sub 3}). The main emphasis of the present article lies on the 'Neuroflame' sensor developed in the authors laboratory yielding the so-called 'flame signature'. A correlation exists between 'flame signature' and excess air. The signal of an optical sensor (in the ultraviolet or infrared) is recorded as a function of time and frequency. After an adequate treatment of this signal, a single parameter is obtained that allows to control the quality of combustion. The sensor has been tested in field tests on various boilers with powers ranging from 100 kW to 18 MW.

    Calorimetry is the most direct dosimetric technique to reach absorbed dose. A calorimeter gives direct access to the energy imparted to matter by ionizing radiation per mass unit by measuring the heat quantity Q produced under irradiation in its sensitive element which is thermally insulated. Graphite was chosen as construction material because all the energy imparted to graphite by ionizing radiation is converted into heat. Thermistors are used for temperature measurements as well as for the electrical heating of the different bodies of the calorimeter. The construction of a calorimeter is the result of a compromise between dosimetric requirements and mechanical constraints. The difficulties encountered are examined and the solutions chosen are detailed. All technical data are gathered in this document. The aim is to provide a practical operative instruction and guidance document, which can help interested laboratories in designing such an instrument. The electrical and thermal tests have shown a good behaviour of the GR9 calorimeter.

No presente trabalho - primeiro a ser publicado sôbre o assunto - são apresentados os resultados de vários ensaios realizados no Laboratório de Sementes da Seção de Botânica, com o objetivo de investigar a causo responsável pelo referido fenômeno e estudar, ao mesmo tempo, a influencio de alguns fatôres sôbre a rapidez e intensidade de sua manifestação. Os resultados mostram que as machucaduras dos grãos, tais como as normalmente ocasionadas pelo beneficiamento mecânico, são a cousa indireta do branqueomento do café. Dentre os fatôres extrínsecos estudados, a umidade relativa do ar foi o que mais influência teve sôbre o fenômeno. Quanto mais elevada, principalmente em níveis superiores a 80%, mais rápida e intensa foi o descoloração dos grãos.Same time after being milled and stored, green coffee becomes normally subject to a phenomenon of discoloration or whitishness of the grains, which causes a considerable loss of its commercial value. In the present paper, which is the first to be published on this question, are reported the results of various experiments carried out in order to investigate the cause of this phenomenon and the influence of some factors on its manifestation. According to these results it may be clearly concluded that the injuries to the grains, such as those which normally result from their mechanical milling, are the indirect cause of the coffee discoloration. Among the studied extrinsic factors, the relative Humidity of air showed to be the most effective of them. The higher the air humidiry, especially on levels above 80%, the more rapid and intense was the manifestation of the phenomenon.

    2009-09-01

    Full Text Available Abstract Background The use of genetically-encoded fluorescent proteins has revolutionized the fields of cell and developmental biology and in doing so redefined our understanding of the dynamic morphogenetic processes that shape the embryo. With the advent of more accessible and sophisticated imaging technologies as well as an abundance of fluorescent proteins with different spectral characteristics, the dynamic processes taking place in situ in living cells and tissues can now be probed. Photomodulatable fluorescent proteins are one of the emerging classes of genetically-encoded fluorescent proteins. Results We have compared PA-GFP, PS-CFP2, Kaede and KikGR four readily available and commonly used photomodulatable fluorescent proteins for use in ES cells and mice. Our results suggest that the green-to-red photoconvertible fluorescent protein, Kikume Green-Red (KikGR, is most suitable for cell labeling and lineage studies in ES cells and mice because it is developmentally neutral, bright and undergoes rapid and complete photoconversion. We have generated transgenic ES cell lines and strains of mice exhibiting robust widespread expression of KikGR. By efficient photoconversion of KikGR we labeled subpopulations of ES cells in culture, and groups of cells within ex utero cultured mouse embryos. Red fluorescent photoconverted cells and their progeny could be followed for extended periods of time. Conclusion Transgenic ES cells and mice exhibiting widespread readily detectable expression of KikGR are indistinguishable from their wild type counterparts and are amenable to efficient photoconversion. They represent novel tools for non-invasive selective labeling specific cell populations and live imaging cell dynamics and cell fate. Genetically-encoded photomodulatable proteins such as KikGR represent emergent attractive alternatives to commonly used vital dyes, tissue grafts and genetic methods for investigating dynamic behaviors of individual cells

O peso dos grãos tem sido um dos critérios utilizados para determinar essa qualidade; porém, para melhor manipular o peso dos grãos nos programas de melhoramento, é necessário o estudo de suas bases genéticas em germoplasma adaptado de aveia. Este trabalho foi realizado com o objetivo de estudar a herança dos caracteres peso de grãos primários e secundários da aveia. Para isso, foram pesadas amostras de 20 grãos primários e secundários de um número variável de plantas nas gerações P1, P2, F1, F2 e F3 de cinco cruzamentos de aveia. Com esses dados, foram obtidas as distribuições de freqüência, variâncias, os efeitos gênicos predominantes, e estimados os valores de herdabilidade no sentido amplo, e usando regressão genitor-progênie. Os resultados mostraram que existe variabilidade em progênies precoces no peso de grãos primários e secundários, e que aditividade e dominância são os efeitos gênicos atuantes. Não foi detectada a presença de genes maiores para a expressão dessas características. Além disso, variações contínuas em F2 e herdabilidades baixas a moderadas indicam que seleção amena pode ser aplicada em gerações iniciais.

    Full Text Available The efficacy of Vectobac GR (potency 200 ITU/mg, a new formulation of bacterial larvicide Bacillus thuringiensis var. israelensis Strain AM65-52, was evaluated against Anopheles gambiae and Culex quinquefasciatus in simulated field and natural habitats in Benin.In simulated field conditions, Vectobac GR formulation was tested at 3 dosages (0.6, 0.9, 1.2 g granules/m² against An. gambiae and 1, 1.5, 2 g granules/m² against Cx. quinquefasciatus according to manufacturer's product label recommendations. The dosage giving optimum efficacy under simulated field conditions were evaluated in the field. The efficacy of Vectobac GR in terms of emergence inhibition in simulated field conditions and of reduction of larval and pupal densities in rice fields and urban cesspits was measured following WHO guidelines for testing and evaluation of mosquito larvicides.Vectobac GR caused emergence inhibition of ≥80% until 21 [20]-[22] days for An. gambiae at 1.2 g/m² dose and 28 [27-29] days for Cx. quinquefasciatus at 2 g/m² in simulated field habitats. The efficacy of Vectobac GR in natural habitats was for 2 to 3 days against larvae and up to 10 days against pupae.Treatment with Vectobac GR caused complete control of immature mosquito within 2-3 days but did not show prolonged residual action. Larviciding can be an option for malaria and filariasis vector control particularly in managing pyrethroid-resistance in African malaria vectors. Since use of larvicides among several African countries is being emphasized through Economic Community of West Africa States, their epidemiological impact should be carefully investigated.

    2012-01-01

    Full Text Available Candida albicans is the most important Candida species causing vulvovaginal candidiasis (VVC. VVC has significant medical and economical impact on women’s health and wellbeing. While current antifungal treatment is reasonably effective, supportive and preventive measures such as application of probiotics are required to reduce the incidence of VVC. We investigated the potential of the probiotics Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 towards control of C. albicans. In vitro experiments demonstrated that lactic acid at low pH plays a major role in suppressing fungal growth. Viability staining following cocultures with lactobacilli revealed that C. albicans cells lost metabolic activity and eventually were killed. Transcriptome analyses showed increased expression of stress-related genes and lower expression of genes involved in fluconazole resistance, which might explain the increased eradication of Candida in a previous clinical study on conjoint probiotic therapy. Our results provide insights on the impact of probiotics on C. albicans survival.

    2007-01-01

    In order to safeguard and to improve the fodder species Hedysarum spinosissimum L subsp.capitatum (desf.) asch. et Gr., we estimated the heritability of certain morphological natures. The model used requires, as a preliminary, the analysis of the variance for the estimate of its components. Families of plants half-sibs, resulting from natural pollination, were analysed. The test of ANOVA shows that the familiy effect is significant for five agronomic characters: l ength of the principal axis ( LO); N umber of the secondary branches ( NTP); (length of the longest secondary branch ( LPL); Date of flowering ( DF); N umber of inflorescences ( NIF). To support the idea of use of these variables in a breeding program, we estimated their heritability. The analysis of the significance of this genetic parameter shows that ultimately three characters only are significantly heritable. They are morphological markers NTP, LPL and which can be retained for any project of family's selection's at H. capitatum.

    The Gröndal Bridge is a large freivorbau bridge (prestressed concrete box bridge), approximately 400 m in length with a free span of 120 m. It was opened to tram traffic in the year 2000. Just after opening cracks were noticed in the webs, these cracks have then increased, the size of the largest...... cracks exceeded 0.5 mm, and at the end of 2001 the bridge was temporarily strengthened. This was carried out with externally placed prestressed steel stays. The reason for the cracking is still debated and will be further discussed in this paper. Nevertheless, it was clear that the bridge needed...... to be strengthened. The strengthening methods used were CFRP plates at the serviceability limit state and prestressed dywidag stays at the ultimate limit state. The strengthening was carried out during 2002. At the same time monitoring of the bridge commenced, using LVDT crack gauges as well as optical fiber sensors....

    The genetics of domestication of yardlong bean [Vigna unguiculata (L.) Walp. ssp. unguiculata cv.-gr. sesquipedalis] is of particular interest because the genome of this legume has experienced divergent domestication. Initially, cowpea was domesticated from wild cowpea in Africa; in Asia a vegetable form of cowpea, yardlong bean, subsequently evolved from cowpea. Information on the genetics of domestication-related traits would be useful for yardlong bean and cowpea breeding programmes, as well as comparative genome study among members of the genus Vigna. The objectives of this study were to identify quantitative trait loci (QTLs) for domestication-related traits in yardlong bean and compare them with previously reported QTLs in closely related Vigna. Two linkage maps were developed from BC(1)F(1) and F(2) populations from the cross between yardlong bean (V. unguiculata ssp. unguiculata cv.-gr. sesquipedalis) accession JP81610 and wild cowpea (V. unguiculata ssp. unguiculata var. spontanea) accession TVnu457. Using these linkage maps, QTLs for 24 domestication-related traits were analysed and mapped. QTLs were detected for traits related to seed, pod, stem and leaf. Most traits were controlled by between one and 11 QTLs. QTLs for domestication-related traits show co-location on several narrow genomic regions on almost all linkage groups (LGs), but especially on LGs 3, 7, 8 and 11. Major QTLs for sizes of seed, pod, stem and leaf were principally located on LG7. Pleiotropy or close linkage of genes for the traits is suggested in these chromosome regions. This is the first report of QTLs for domestication-related traits in yardlong bean. The results provide a foundation for marker-assisted selection of domestication-related QTLs in yardlong bean and enhance understanding of domestication in the genus Vigna.

    Immunosuppressive CD11b+Gr-1+ myeloid-derived suppressor cells (MDSC) accumulate in the livers of tumor-bearing mice. We studied hepatic MDSC in two murine models of immune mediated hepatitis. Unexpectedly, treatment of tumor bearing mice with Concanavalin A or α-Galactosylceramide resulted in increased ALT and AST serum levels in comparison to tumor free mice. Adoptive transfer of hepatic MDSC into naïve mice exacerbated Concanavalin A induced liver damage. Hepatic CD11b+Gr-1+ cells revealed a polarized pro-inflammatory gene signature after Concanavalin A treatment. An interferon gamma- dependent up-regulation of CD40 on hepatic CD11b+Gr-1+ cells along with an up-regulation of CD80, CD86, and CD1d after Concanavalin A treatment was observed. Concanavalin A treatment resulted in a loss of suppressor function by tumor-induced CD11b+Gr-1+ MDSC as well as enhanced reactive oxygen species-mediated hepatotoxicity. CD40 knockdown in hepatic MDSC led to increased arginase activity upon Concanavalin A treatment and lower ALT/AST serum levels. Finally, blockade of arginase activity in Cd40−/− tumor-induced myeloid cells resulted in exacerbation of hepatitis and increased reactive oxygen species production in vivo. Our findings indicate that in a setting of acute hepatitis, tumor-induced hepatic MDSC act as pro-inflammatory immune effector cells capable of killing hepatocytes in a CD40-dependent manner.

    Food constituents may cause a phenomenon of food-drug interactions. In the current study, we examined the effects of artificial sweeteners (aspartame, acesulfame, cyclamate, saccharin) on the aryl hydrocarbon receptor (AhR) and glucocorticoid receptor (GR)-dependent expression of CYP1A1 in human hepatocytes, hepatic HepG2 and intestinal LS174T cancer cell lines. Sweeteners were tested in concentrations up to those occurring in non-alcoholic beverages. Basal and ligand-inducible AhR- and GR-dependent reporter gene activation in stably transfected HepG2 and HeLa cells, respectively, were not affected by either of the sweeteners tested after 24h of incubation. The expression of CYP1A1 mRNA and protein in primary cultures of human hepatocytes and in LS174T and HepG2 cells was not induced by any of the tested sweeteners. Overall, aspartame, acesulfame, saccharin and cyclamate had no effects on CYP1A1 expression and transcriptional activities of AhR and GR. These data imply the safety of artificial sweeteners in terms of interference with AhR, GR and CYP1A1. Copyright © 2013 Elsevier Ltd. All rights reserved.

As análises de danos dos grãos de arroz ocorreram com 7 e 14 dias após o início dos experimentos separando os insetos praga dos grãos. As maiores perdas ocorreram com o aumento de temperatura e densidade de infestação; a coexistência S. zeamais + L. minutus apresentou os maiores efeitos de predação. Conclui-se que temperaturas mais baixas e monitoramento e controle de infestação de insetos praga primários e secundários reduzem a perda de grãos de arroz armazenados.

  13. Further studies of the stability of LiF:Mg,Cu,P (GR-200) at maximum readout temperatures between 240oC and 280oC

    1996-01-01

    It has recently been shown that LiF:Mg,Cu,P (GR-200) can be read out to temperatures as high as 270 o C for 12 s with negligible loss in sensitivity. In the present work the long-term sensitivity of GR-200 was studied at readout temperatures between 240 o C and 280 o C. The idea was that the readout temperatures above 240 o C might initiate reaction processes which influence the sensitivity only after long-term storage. No difference was found in the behaviour of GR-200 chips with 80 accumulated readouts to 240 o C or 270 o C and after storage of up to four months. Slight losses in sensitivity of 4% for 240 o C and 10% for 270 o C are observed after 80 readouts during four months storage. However, at a maximum readout temperature of 280 o C, a 33% loss in sensitivity after 80 cycles is observed. In conclusion it is found that GR-200 can be read out at temperatures as high as 270 o C with negligible loss in sensitivity (less than 0.1% per readout following an initialisation procedure of 1 readout) and acceptable residual signal (0.6%).

    Inflammatory microenvironments play a key role in skeletal muscle regeneration. The infiltration of CD8 T cells into injured muscle has been reported. However, the role of CD8 T cells during skeletal muscle regeneration remains unclear. In this study, we used cardiotoxin-induced mouse skeletal muscle injury/regeneration model to investigate the role of CD8 T cells. Muscle regeneration was impaired and matrix deposit was increased in CD8α-deficient mice compared with wild-type (WT) mice whose CD8 T cells were infiltrated into damaged muscle after cardiotoxin injection. Adoptive transfer of CD8 T cells to CD8α-deficient mice improved muscle regeneration and inhibited matrix remodeling. Compared with WT mice, CD8α deficiency limited the recruitment of Gr1(high) macrophages (MPs) into muscle, resulting in the reduction of satellite cell number. The expression of MCP-1 (MCP-1/CCL2), which regulates the migration of Gr1(high) MPs, was reduced in CD8α-deficient mice compared with WT mice. Coculture CD8 T cells with MPs promoted MCP-1 secretion. The i.m. injection of MCP-1 markedly promoted the recruitment of Gr1(high) MPs and improved muscle regeneration in CD8α-deficient mice. We conclude that CD8 T cells are involved in skeletal muscle regeneration by regulating the secretion of MCP-1 to recruit Gr1(high) MPs, which facilitate myoblast proliferation.

  16. Elevated utero/placental GR/NR3C1 is not required for the induction of parturition in the dog.

    2016-10-01

    The endocrine mechanisms that lead to initiation of parturition in dogs are still not fully understood. The prepartum luteolysis is associated with increased prostaglandin (PG) F2α secretion; however, there is no pregnancy- or parturition-related increase in estrogens. Moreover, unlike in other mammalian species, in the dog, increased peripartum levels of cortisol measured sporadically in maternal peripheral blood are not mandatory for normal parturition. Nevertheless, auto/paracrine effects of cortisol at the placental feto-maternal level cannot be excluded. Therefore, the aim of this study was to investigate the expression and localization of glucocorticoid receptor (GR/NR3C1) in canine utero/placental (Ut/Pl) units and uterine interplacental sites at selected time points during pregnancy (pre-implantation, post-implantation and mid-gestation), and at normal and antigestagen-induced parturition. The Ut/Pl expression of GR/NR3C1 did not change significantly from pre-implantation until mid-gestation; however, it was strongly induced during the prepartum luteolysis. Within the interplacental samples, expression of GR/NR3C1-mRNA was greater post-implantation than pre-implantation and did not change afterward, i.e. toward mid-gestation. Compartmentalization studies within the Ut/Pl units, involving placenta, endometrium and myometrium separately, performed at the prepartum luteolysis revealed the highest GR/NR3C1-mRNA levels in placenta compared with endometrium and myometrium. Interestingly, in antigestagen-treated mid-pregnancy dogs, Ut/Pl and interplacental GR/NR3C1-mRNA expression remained unaffected. At the cellular level, placental GR/NR3C1 was clearly detectable in placenta fetalis, i.e. in trophoblast cells. In conclusion, increased expression of GR/NR3C1 during normal parturition, but not following antigestagen-treatment, suggest that it is not required for initiating the signaling cascade of PG synthesis leading to the induction of parturition in the dog.

Neste artigo, gráficos de controle binomial estão sujeitos às mesmas exigências. Estudo subsequente revela que este gráfico apresenta resultados um tanto atraentes sob vários aspectos, como por exemplo, seu poder de detecção. Uma versão do mesmo gráfico empregando estimadores de p também é apresentada no caso de p ser desconhecido.For processes concerning attribute data with (very small failure rate p, often negative binomial control charts are used. The decision whether to stop or continue is made each time r failures have occurred, for some r >1. Finding the optimal r for detecting a given increase of p first requires alignment of the charts in terms of in-control behavior. In the present paper binomial charts are subjected to this same requirement. Subsequent study reveals that the resulting charts are quite attractive in several aspects, such as detection power. For the case of unknown p, an estimated version of the chart is derived and studied.

    Electronic structure and carrier behavior in semiconductor junctions can be effectively modulated on the application of strain. This work represents the first demonstration of a large-area, flexible, paper-based graphene-molybdenum disulfide (Gr/MoS2) broadband photodetector using a low-cost solution-processed hydrothermal method and enhancement in photodetection through strain modulation by assembling the device on polydimethylsiloxane. Optimization, in terms of process parameters, was carried out to obtain trilayer MoS2 over Gr-cellulose paper. Under strain, potential barrier variation and piezopotential induced in MoS2 leads to 79.41% enhancement in photodetection in the visible region. Piezopotential induced in MoS2 lowers the conduction-band energy thereby increasing the effective electric field favoring easy electron-hole separation. The advantage of vertically stacked Gr/MoS2 for the photodetector is the utilization of the entire area as a junction where effective separation of electron-hole pairs occurs. Detailed studies of the mechanism in terms of potential barrier variation in Gr/MoS2 and an energy-band diagram are presented to help understand the proposed phenomenon. The present work demonstrates the significance of few-layer MoS2 or Gr in relation to strain-modulated photosensing in comparison to their counterparts grown via chemical vapor deposition. The results provide an excellent approach for the fabrication of low-cost heterojunctions for improved optoelectronic performance, which can be further extended to similar 2D-material heterojunctions for analog, digital and optoelectronic applications.

  19. Grèzes litées and their genesis: the site of Enscherange in the Rhenish-Ardennes Massif as a case study

    Full Text Available The freeze-thaw cycles in periglacial areas during the Quaternary glacials increased frost weathering, leading to a disintegration of rock formations. Transported downslope, clasts allowed in some areas the formation of stratified slope deposits known as “grèzes litées”. This study reviews the existing theories and investigates the grèzes litées deposits of Enscherange and Rodershausen in Luxembourg. This process was reinforced by the lithostructural control of the parent material expressed by the dip of schistosity (66° and its orientation parallel to the main slopes in the area. This gave opportunities to activate the frost-weathering process on top of the ridge where the parent material outcropped. As the stratified slope deposits have a dip of 23° and as there is no significant lateral variation in rock fragment size, slope processes that involve only gravity are excluded and transportation in solifluction lobes with significant slopewash and sorting processes is hypothesized. The Enscherange formation, the biggest known outcrop of grèzes litées in north-western Europe, shows evidence of clear layering over the whole profile depth. A palaeolandscape reconstruction shows that ridges must have been tens of metres higher than presently. The investigation of the matrix composition shows Laacher See tephra in the overlying periglacial cover bed with infiltrations of the minerals in the reworked upper layer of the grèzes litées deposit. Chronostratigraphic approaches using the underlying cryoturbation zone and Laacher See heavy minerals in the overlying topsoil place the formation of grèzes litées deposits in the Late Pleistocene.

A dieta-controle foi formulada com feno de aveia, farelo de soja, milho moído e suplemento vitamínico-mineral. Os pesos da carcaça quente e fria e os rendimentos da carcaça e de cortes comerciais não foram modificados pelos tratamentos. A dieta com grãos de canola resultou em maior perda por resfriamento da carcaça e menor proporção de gordura no lombo, e a proporção de osso no lombo foi maior para os animais que receberam linhaça ou canola. Os teores de umidade, proteína, lipídios totais e cinzas do músculo Longissimus dorsi não foram alterados com a adição dos grãos de oleaginosas. A dieta com grãos de linhaça resultou em aumento do teor de ômega-3 no músculo, e o teor de colesterol e a razão ômega-6/ômega-3 foram menores nos tratamentos que continham linhaça, girassol e canola. A inclusão dos grãos de oleaginosas nas dietas não alterou as características quantitativas da carcaça de cabritos Saanen, mas melhorou a qualidade da carne, que apresentou menos colesterol e mais ômega-3, com o uso de linhaça.

    Full Text Available A audiodescrição (AD é a tradução em palavras dos elementos visuais de uma produção audiovisual, tais como filmes, peças de teatro, jogos esportivos, obras de arte, dentre outros. A AD torna acessíveis essas produções audiovisuais a pessoas com deficiência visual. A pesquisa em AD de filmes vem se destacando dos demais tipos de AD, envolvendo tanto estudos descritivos quanto exploratórios. Este trabalho tem o objetivo de apresentar os resultados de um desses estudos desenvolvidos pelo grupo de estudo LEAD (Legendagem e Audiodescrição na Universidade Estadual do Ceará (UECE, no âmbito do projeto de cooperação entre a UECE e a UFMG (PROCAD. O estudo em questão abordou a recepção de pessoas com deficiência visual ao filme O Grão, do cineasta cearense Petrus Cariry (2007. O filme fez parte de duas mostras de cinema acessível realizadas pelo LEAD, que cuidou do roteiro, gravação e edição. O LEAD também produziu O Grão em DVD, contendo menu com audionavegação, audiodescrição, legenda para surdos e janela de LIBRAS. A metodologia compreendeu uma dimensão descritiva, que classificou e analisou as inserções das descrições contidas no roteiro de AD, e outra exploratória, que aplicou um teste de recepção sobre a AD do filme com dois grupos de pessoas com deficiência visual, sendo um grupo com cegueira congênita e total e o outro com baixa visão. Após assistir ao filme, o participante com deficiência visual fazia um relato livre sobre sua compreensão do enredo do filme. Por fim, respondia a um questionário versando sobre a opinião deles sobre a AD. Todo o processo era filmado para que também as reações ao filme pudessem fazer parte dos protocolos de análise. Foram consideradas duas variáveis: o espectador com deficiência visual e o gênero do filme. Os resultados mostraram que não houve diferença de recepção entre os dois grupos analisados, visto que os quatro participantes entenderam e apreciaram

    2017-08-01

    Full Text Available The purpose of this paper is to introduce, edit and translate an unpublished fragment of Byzantine medical writing. Parisinus suppl. gr. 607 preserves a short and seemingly acephalous anthology of pharmaceutical remedies.  A consideration of recipe collections as a distinctive but hard-to-define species of Byzantine Fachliteratur seeks to integrate this text into recent scholarship concerning a broad category of informal therapeutic writings, which testify to Byzantine drug lore, clinical practice and medicinal book culture. Investigation of the codicological structure clarifies that a secondary hand copied the fragment onto a blank folio in the mid-tenth century, contemporary with the compilation this manuscript in a high socio-cultural and intellectual milieu in Constantinople. Examination of compositional contexts, embracing philological, textual, literary-historical and medical dimensions, suggests a ‘private’ remedy collection indicative of the use of texts in ‘household medicine’. This fragment draws particular attention as one of the earliest surviving specimens, while the codex has escaped the notice of previous inventories of Greek manuscripts with medical content.

    Retained austenite(RA) usually presents in the quenched Nuclear Pressure-Vessel SA508 Gr.3 steel. In the present work, the characteristic of RA decomposition and its effect on the impact toughness were investigated by microstructure observation, dilatometric experiments and Charpy impact tests. The results show that the RA transformed into martensite and bainite during tempering at 230 °C and 400 °C respectively, while mixture of long rod carbides and ferrite formed at 650 °C. The long rod carbides formed from RA decomposition decrease the critical cleavage stress for initiation of micro-cracks, and deteriorate the impact toughness of the steel. Pre-tempering at a low temperature such as 230 °C or 400 °C leading to the decomposition of RA into martensite or baintie can eliminate the deterioration of the toughness caused by direct decomposition into long rod carbides. The absorbed energy indicate that pre-tempering at 400 °C can drive dramatically improvement in the toughness of the steel.

    To determine the ability of probiotic lactobacilli to improve the treatment of vulvovaginal candidiasis (VVC) using a randomized, double-blind and placebo-controlled trial. Fifty-five women diagnosed with VVC by vaginal discharge positive for Candida spp. (according to culture method) associated with at least one of the symptoms (itching and burning vaginal feeling, dyspareunia and dysuria), were treated with single dose of fluconazole (150 mg) supplemented every morning for the following 4 weeks with two placebo or two probiotic capsules (containing Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14). At 4 weeks, the probiotic treated group showed significantly less vaginal discharge associated with any of the above mentioned symptoms (10.3%vs 34.6%; P = 0.03) and lower presence of yeast detected by culture (10.3%vs 38.5%; P = 0.014). This study has shown that probiotic lactobacilli can increase the effectiveness of an anti-fungal pharmaceutical agent in curing disease. This novel finding of probiotic lactobacilli augmenting the cure rate of yeast vaginitis, not only offers an alternative approach to a highly prevalent condition that adversely affects the quality of life of women around the world, but also raises the question of how this combination works.

    Various bacterial, fungal, parasitic, and viral pathogens can cause folliculitis, which is often mistakenly treated with antibiotics for months or even years. A laboratory diagnosis is required before therapy can be planned. Here, we describe the prevalence and risk factors, as well as the clinical, cytological, and mycological characteristics, of patients with Malassezia folliculitis (MF) in Adana, Turkey. We also report the treatment responses of the MF patients and describe the Malassezia spp. using culture-based molecular methods. Cytological examinations were performed in 264 folliculitis patients, 49 of whom (18.5%) were diagnosed with MF. The positivity of the May-Grünwald-Giemsa (MGG) smear was higher (100%) than that of the potassium hydroxide test (81.6%). Using Wood's light, yellow-green fluorescence was observed in 66.7% of the MF patients. Identification using the rDNA internal transcribed spacer region revealed that Malassezia globosa was the most common species, followed by Malassezia sympodialis, Malassezia restricta, and Malassezia furfur. The MF patients were treated with itraconazole capsules (200 mg/d) for 2 weeks. Complete recovery was observed in 79.6% of the patients. These novel findings help improve our current understanding of the epidemiological characteristics of MF and establish MGG as a practical tool for the diagnosis of MF. Copyright © 2013 Elsevier Inc.

  9. Subcontracting relations and their effects on safety and security in two firms: SNCF and GrDF

    Because of economical processes that tend to move the frontiers of firms salaried relations of uncertain status are found coexisting inside the very same working world. From a qualitative investigation mixing employees' interviews and observations made on SNCF and GrDF working sites our research offers to think about the relations linking subcontracting, maintenance, safety and security. Considering subcontracting as a particular way for professional bodies to be associated allows us to wonder about its effects within a same firm (the 'integrated' subcontracting) as much as between a principal and a provider. Our thesis shows that when change occurs inside the organization - like the creation of new committees of experts or the reorganizing of an old service - security and safety can be impacted because thus professional bodies tend to be reconfigured while modifications affect practices, professional identities and work division. The relations between subcontractors and principal are complicated and their consequences depend from the context they are placed in, determined by a combination of various characteristics such as the confidence level, the available time, the reputation, the position occupied by the subcontractor. Our investigation makes clear that there is no direct link between subcontracting, security and safety. Their effects, in spite of their reality, are submitted to the altering mediation of legal factors (related to economic national and European issues) and concern the working organization as well as the professional identities.

    Full Text Available Abstract Background Epithelial cells of the urinary tract recognize pathogenic bacteria through pattern recognition receptors on their surface, such as toll-like receptors (TLRs, and mount an immune response through the activation of the NF-kappaB pathway. Some uropathogenic bacteria can subvert these cellular responses, creating problems with how the host eliminates pathogens. Lactobacillus is a genus of lactic acid bacteria that are part of the microbiota and consist of many probiotic strains, some specifically for urogenital infections. Immunomodulation has emerged as an important mode of action of probiotic and commensal lactobacilli and given the importance of epithelial cells, we evaluated the effect of the urogenital probiotic Lactobacillus rhamnosus GR-1 on epithelial immune activation. Results Immune activation through the NF-kappaB pathway was initiated by stimulation of T24 urothelial cells with heat-killed Escherichia coli and this was further potentiated when cells were co-cultured with live L. rhamnosus GR-1. Heat-killed lactobacilli were poor activators of NF-kappaB. Concomitant stimulation of bladder cells with E. coli and L. rhamnosus GR-1 increased the levels of the pro-inflammatory cytokine TNF, whereas IL-6 and CXCL8 levels were reduced. Another probiotic, L. rhamnosus GG, was also able to potentiate NF-kappaB in these cells although at a significantly reduced level compared to the GR-1 strain. The transcript numbers and protein levels of the lipopolysaccharide receptor TLR4 were significantly increased after co-stimulation with E. coli and lactobacilli compared to controls. Furthermore, inhibition of TLR4 activation by polymixin B completely blocked the lactobacilli potentiation of NF-kappaB. Conclusions The immunological outcome of E. coli challenge of bladder cells was influenced by probiotic L. rhamnosus GR-1, by enhancing the activation of NF-kappaB and TNF release. Thus the urogenital probiotic L. rhamnosus GR-1

No pinhão-manso, a produtividade de grãos é o principal alvo do programa de melhoramento, porém existem outros caracteres importantes que impactam na produção. Diante desse contexto, o objetivo deste trabalho foi estimar, por meio de análise de trilha, os efeitos diretos e indiretos de caracteres vegetativos sobre a produtividade de grãos de pinhão-manso. Aos 18 meses após o plantio, foram mensurados os caracteres altura de plantas, diâmetro do caule, número de ramos por planta, projeção da copa na linha, projeção da copa na entrelinha e produtividade de grãos. Foram estimadas as correlações fenotípicas entre os caracteres avaliados, sendo essas correlações desdobradas, por meio da análise de trilha, em efeitos diretos e indiretos, considerando-se o caráter produtividade de grãos como a variável dependente principal. Observou-se que 76% da variação em produtividade foi explicada pelas variáveis explicativas, valor este superior ao observado em outros estudos e adequado para explorar os ganhos com a seleção direta e indireta em pinhão-manso. Os caracteres diâmetro do caule, massa de cem sementes e projeção da copa na entrelinha influenciam diretamente a produtividade de grãos, sendo indicados para seleção direta, assim como para a seleção indireta de progênies superiores de pinhão-manso para produtividade de grãos.

    Full Text Available In practice, sometimes the process data did not come from a known population distribution. So the commonly used Shewhart variables control charts are not suitable since their performance could not be properly evaluated. In this paper, we propose a new EWMA Control Chart based on a simple statistic to monitor the small mean shifts in the process with non-normal or unknown distributions. The sampling properties of the new monitoring statistic are explored and the average run lengths of the proposed chart are examined. Furthermore, an Arcsine EWMA Chart is proposed since the average run lengths of the Arcsine EWMA Chart are more reasonable than those of the new EWMA Chart. The Arcsine EWMA Chart is recommended if we are concerned with the proper values of the average run length.Na prática a distribuição de probabilidade de muitas variáveis não é conhecida e sabe-se que não é proveniente de uma distribuição normal. Segue que o uso dos gráficos de controle Shewhart não é conveniente e daí há necessidade de procurar outros gráficos de controle alternativos. Neste artigo um novo gráfico de controle do tipo EWMA é proposto. Ele utiliza uma estatística não paramétrica para monitorar a média de um processo e observou-se que é ágil para detectar pequenos desvios da média. Propriedades amostrais da estatística são exploradas e um exemplo ilustra a nova proposta. Além disto, outro gráfico do tipo EWMA é apresentado utilizando como estatística o arco-seno da estatística não paramétrica. Os valores de ARL’s deste gráfico apresentaram melhor desempenho do que a proposta anterior. Desta forma o gráfico Arco-Seno EWMA é recomendado se o critério do ARL for empregado.

In discussing this capacity, the article evaluates the evolution of fundamental conditions of efficiency of the colony, considering them as determined by the peculiar features that assumed the local operation of the colonial project in Grão-Pará. These conditions, strongly characterized by the uniqueness of the natural foundations of the Amazonian biome, are evaluated in reference to the institutional changes that mark in time the trajectory of the regional economy and society.

  16. Continuous state-space representation of a bucket-type rainfall-runoff model: a case study with the GR4 model using state-space GR4 (version 1.0)

    Santos, Léonard; Thirel, Guillaume; Perrin, Charles

    2018-04-01

    In many conceptual rainfall-runoff models, the water balance differential equations are not explicitly formulated. These differential equations are solved sequentially by splitting the equations into terms that can be solved analytically with a technique called operator splitting. As a result, only the solutions of the split equations are used to present the different models. This article provides a methodology to make the governing water balance equations of a bucket-type rainfall-runoff model explicit and to solve them continuously. This is done by setting up a comprehensive state-space representation of the model. By representing it in this way, the operator splitting, which makes the structural analysis of the model more complex, could be removed. In this state-space representation, the lag functions (unit hydrographs), which are frequent in rainfall-runoff models and make the resolution of the representation difficult, are first replaced by a so-called Nash cascade and then solved with a robust numerical integration technique. To illustrate this methodology, the GR4J model is taken as an example. The substitution of the unit hydrographs with a Nash cascade, even if it modifies the model behaviour when solved using operator splitting, does not modify it when the state-space representation is solved using an implicit integration technique. Indeed, the flow time series simulated by the new representation of the model are very similar to those simulated by the classic model. The use of a robust numerical technique that approximates a continuous-time model also improves the lag parameter consistency across time steps and provides a more time-consistent model with time-independent parameters.

  2. Structural variants of glucocorticoid receptor binding sites and different versions of positive glucocorticoid responsive elements: Analysis of GR-TRRD database.

    Merkulov, Vasily M; Merkulova, Tatyana I

    2009-05-01

    The GR-TRRD section of the TRRD database contains the presently largest sample of published nucleotide sequences with experimentally confirmed binding to the glucocorticoid hormone receptor (GR). This sample comprises 160 glucocorticoid receptor binding sites (GRbs) from 77 vertebrate glucocorticoid-regulated genes. Analysis of this sample has demonstrated that the structure of only half GRbs (54%) corresponds to the generally accepted organization of glucocorticoid response element (GRE) as an inverted repeat of the TGTTCT hexanucleotide. As many as 40% of GRbs contain only the hexanucleotide, and the majority of such "half-sites" belong to the glucocorticoid-inducible genes. An expansion of the sample allowed the consensus of GRbs organized as an inverted repeat to be determined more precisely. Several possible mechanisms underlying the role of the noncanonical receptor binding sites (hexanucleotide half-sites) in the glucocorticoid induction are proposed based on analysis of the literature data.

    Toll-like receptors (TLRs) and glucocorticoid receptor (GR) act respectively as effectors of innate immune and stress responses. The crosstalk between them is critical for the maintenance of homeostasis during the immune response. Vaccination is known to boost adaptive immunity, yet it remains elusive whether vaccination may affect GR/TLR interactions following infection. Duroc×Meishan crossbred piglets were allocated to three groups. The control group (CC) received neither vaccination nor infection; the non-vaccinated infection group (NI) was artificially infected intratracheally with Mycoplasma hyopneumoniae (M. hyopneumoniae); while the vaccinated, infected group (VI) was vaccinated intramuscularly with inactivated M. hyopneumoniae one month before infection. The clinical signs and macroscopic lung lesions were significantly reduced by vaccination. However, vaccination did not affect the concentration of M. hyopneumoniae DNA in the lung. Serum cortisol was significantly decreased in both NI and VI pigs (Phyopneumoniae-induced lung lesions in the pig. Copyright © 2013 Elsevier B.V. All rights reserved.

Três experimentos foram instalados no campo, nos anos de 1994-1995 a 1996-1997, com os híbridos comerciais C-901, XL-560 e XL-678, em 1994/95, e os híbridos C-901, XL-212 e XL-370, nos outros anos. Os tratamentos consistiram em diferentes datas de plantio de setembro a dezembro, em 1994/95, e de agosto a dezembro, em 1995/96 e 1996/97. A taxa efetiva do enchimento dos grãos foi diretamente dependente da temperatura média do ar, tendo sido maior nos plantios mais precoces, e resultando em grãos mais pesados do que os obtidos em plantios mais tardios. Nos plantios mais tardios, a menor temperatura do ar durante o período efetivo do enchimento dos grãos propiciou menor taxa de enchimento dos grãos, tornando-os mais leves. Conclui-se que o principal fator limitante do rendimento de grãos nesses plantios é a fonte produtora de fotoassimilados, e não a capacidade dos grãos em acumulá-los.The objective of this work was to study the effect of different sowing dates on the rate and duration of the grain filling and how such factors determine the final grain weight of a number of maize (Zea mays L. hybrids.

The treatments consisted of sowing dates from September to December, in 1994/95, and from August to December, in 1995/96 and 1996/97. The effective grain filling rate depended directly on the mean air temperature and it was higher in earlier plantings, resulting in heavier grains, as compared to the grains obtained in the later sowings.

  9. Source parameters for the 2013-2015 earthquake sequence in Nógrád county, Hungary

    Wéber, Zoltán

    2016-07-01

    Between 2013 June and 2015 January, 35 earthquakes with local magnitude M L ranging from 1.1 to 4.2 occurred in Nógrád county, Hungary. This earthquake sequence represents above average seismic activity in the region and is the first one that was recorded by a significant number of three-component digital seismographs in the county. Using a Bayesian multiple-event location algorithm, we have estimated the hypocenters of 30 earthquakes with M L ≥1.5. The events occurred in two small regions of a few squared kilometers: one to the east of Érsekvadkert and the other at Iliny. The uncertainty of the epicenters is about 1.5-1.7 km in the E-W direction and 1.8-2.1 km in the N-S direction at the 95 % confidence level. The estimated event depths are confined to the upper 3 km of the crust. We have successfully estimated the full moment tensors of 4 M w ≥3.6 earthquakes using a probabilistic waveform inversion procedure. The non-double-couple components of the retrieved moment tensor solutions are statistically insignificant. The negligible amount of the isotropic component implies the tectonic nature of the investigated events. All of the analyzed earthquakes have strike-slip mechanism with either right-lateral slip on an approximately N-S striking or left-lateral movement on a roughly E-W striking nodal plane. The orientations of the obtained focal mechanisms are in good agreement with the main stress pattern published for the epicentral region. Both the P and T principal axes are horizontal, and the P axis is oriented along a NE-SW direction.

    Full Text Available http://dx.doi.org/10.5007/1807-9288.2013v9n1p150   O poeta André Vallias configura-se como um dos nomes pioneiros da poesia digital. Em 1991, foi curador, juntamente com Friedrich Block, da “Primeira Mostra Internacional de Poesia Digital”, a P0es1s, e publicou poemas multimídias e hipermídias em sites e antologias nacionais e internacionais. Em um artigo intitulado “Nous n’avons pas compris Descartes”, Vallias define uma concepção de poema que guiará a sua primeira série de poemas digitais – poemas gráficos, poemas-diagramas –, e retomada nas suas produções multimídia e hipermídia subsequentes. Trata-se da visão do poema como um “diagrama aberto”, um poema que se constrói a partir de uma interrelação de códigos, liberto da predominância do signo verbal, dotados de intermidialidade. Este artigo propõe uma interpretação de três poemas desta primeira série, desenvolvidos através do software de desenho AutoCAD e posteriormente remediados para a interface da Web. As interpretações visam, em primeiro lugar, iluminar alguns dos possíveis sentidos desenvolvidos pelos poemas; e, em segundo, apontar a relação que os poemas estabelecem, por suas características, com aspectos da poética digital como um todo.

  11. Time dependence of volcano inflation: mass influx or viscoelastic relaxation? Insights from Grímsvötn volcano, Iceland

    Segall, P.

    2017-12-01

    Distinguishing magma chamber pressurization from relaxation of a viscoelastic aureole surrounding the chamber based on geodetic measurements has remained challenging. Elastic models with mass inflow proportional to the pressure difference between the chamber and a deep reservoir predict exponentially decaying flux. For a spherical chamber surrounded by a Maxwell viscoelastic shell with pressure dependent recharge, the surface deformation is the sum of two exponentials (Segall, 2016). GPS displacements following eruptions of Grímsvötn, Iceland in 2004 and 2011 exhibit rapid post-eruptive inflation (time scale of 0.1 yr), followed by inflation with a much longer time constant. Markov Chain Monte Carlo inversion with the viscoelastic model shows the GPS time series can be fit with viscosity of 2e16 Pa-s, and a relatively incompressible magma, B = beta_c/ (beta_m + beta_c) > 0.6, where beta_m and beta_c are chamber and magma compressibility. The latter appears to conflict with the ratio of erupted volume to geodetically inferred source volume change, rv 10, obtained for the best fitting spherical (Mogi ) source (Hreinsdóttir, 2014). Since rv = 1/B, this implies a relatively compressible melt, B 0.1. Reexamination of the co-eruptive GPS and tilt data with the more general ellipsoidal model of Cervelli (2013), reveals that the best fitting sources are oblate (b/a 3), deeper, and with larger volume changes, rv 3, relative to spherical models. Oblate magma chambers are consistent with seismic tomography. FEM calculations including free surface effects lead to even larger co-eruptive volume changes, smaller rv and hence larger B. I conclude that the data are consistent with rapid post-eruptive inflation driven by viscoelastic relaxation with a relatively incompressible magma, although other interpretations will be discussed.

    It has been suggested that during a migraine attack trigeminal nerves release calcitonin gene-related peptide (CGRP), producing central nociception and vasodilatation of cranial arteries, including the extracranial branches of the external carotid artery. Since trigeminal inhibition may prevent this vasodilatation, the present study has investigated the effects of intrathecal dihydroergotamine on the external carotid vasodilatation to capsaicin, α-CGRP and acetylcholine. Anaesthetized vagosympathectomized dogs were prepared to measure blood pressure, heart rate and external carotid conductance. A catheter was inserted into the right common carotid artery for the continuous infusion of phenylephrine (to restore the carotid vascular tone), whereas the corresponding thyroid artery was cannulated for one-min intracarotid infusions of capsaicin, α-CGRP and acetylcholine (which dose-dependently increased the external carotid conductance). Another cannula was inserted intrathecally (C(1)-C(3)) for the administration of dihydroergotamine, the α(2)-adrenoceptor antagonist rauwolscine or the serotonin 5-HT(1B/1D) receptor antagonist GR127935 (N-[4-methoxy-3-(4-methyl-1-piperazinyl) phenyl]-2'-methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)[1,1-biphenyl]-4-carboxamide hydrochloride monohydrate). Intrathecal dihydroergotamine (10, 31 and 100μg) inhibited the vasodilatation to capsaicin, but not that to α-CGRP or acetylcholine. This inhibition was: (i) unaffected by 10μg GR127935 or 100μg rauwolscine, but abolished by 31μg GR127935 or 310μg rauwolscine at 10μg dihydroergotamine; and (ii) abolished by the combination 10μg GR127935+100μg rauwolscine at 100μg dihydroergotamine. Thus, intrathecal (C(1)-C(3)) dihydroergotamine seems to inhibit the external carotid vasodilatation to capsaicin by spinal activation of serotonin 5-HT(1B/1D) (probably 5-HT(1B)) receptors and α(2) (probably α(2A/2C))-adrenoceptors.

    2, 4-dichlorophenol (2, 4-DCP) is considered to be a highly toxic, mutagenic, and possibly carcinogenic pollutant. This study is focused on the electrochemical oxidation of 2, 4-DCP on nanostructured 3D-porous Ti/Sb-SnO 2 -Gr anodes, with the aim of presenting a comprehensive elucidation of mineralization process through the investigation of influential kinetics, the reactivity of hydroxyl radical's and analysis of intermediates. High efficiency was achieved at pH of 3 using Na 2 SO 4 electrolytes at a current density of 30 mA cm -2 . Under the optimized conditions, a maximum removal of 2, 4-DCP of up to 99.9% was reached, whereas a TOC removal of 81% was recorded with the lowest EC TOC (0.49 kW h g -1 ) within 40 min of electrolysis. To explore the stability of the 3D-Ti/Sb-SnO 2 -Gr electrodes, a continuous electrochemical operation was established, and the consistent mineralization results indicated the effectiveness of the 3D-Ti/Sb-SnO 2 -Gr system concerning its durability and practical utilization. EPR studies demonstrated the abundant generation of OH radicals on 3D-Ti/Sb-SnO 2 -Gr, resulting in fast recalcitrant pollutant incineration. From dechlorination and the reactivity of the OH radicals, several intermediates including six cyclic byproducts and three aliphatic carboxylic acids were detected, and two possible degradation pathways were proposed that justify the complete mineralization of 2, 4-DCP.

    To prevent such critical matters above mentioned, investigation about degradation mechanism of materials by thermal aging should be conducted. However, there are no sufficient studies on this field. Therefore, the final goal of this study is to investigate microstructure along the DMW undergone thermal aging process. Firstly, in order to get a reference data for further comparison analysis which is expected to show degradation mechanism of the weld joint, un-heated weld joint was investigated with several instruments, Vickers hardness tester, scanning electron microscope (SEM), and an energy-dispersive X-ray spectrometer (EDS). Detail instrumental analysis in Alloy 600 - Alloy 182 - A508 Gr. 3 DMW joint were performed in order to investigate microstructure and mechanical properties of material. Following conclusions can be drawn from this study. Alloy 182 has austenitic dendrite structure which is formed by heat flow during welding process. Type-II boundaries were observed at the interface between Alloy 182 and A508 Gr. 3. Chemical composition shows rapid transition at the interface which makes 3000 µm of chromium dilution zone. Microstructure of A508 Gr. 3 was investigated from the interface between Alloy 182 to base metal

  1. CXCL17 expression by tumor cells recruits CD11b+Gr1 high F4/80- cells and promotes tumor progression.

    Aya Matsui

    Full Text Available BACKGROUND: Chemokines are involved in multiple aspects of pathogenesis and cellular trafficking in tumorigenesis. In this study, we report that the latest member of the C-X-C-type chemokines, CXCL17 (DMC/VCC-1, recruits immature myeloid-derived cells and enhances early tumor progression. METHODOLOGY/PRINCIPAL FINDINGS: CXCL17 was preferentially expressed in some aggressive types of gastrointestinal, breast, and lung cancer cells. CXCL17 expression did not impart NIH3T3 cells with oncogenic potential in vitro, but CXCL17-expressing NIH3T3 cells could form vasculature-rich tumors in immunodeficient mice. Our data showed that CXCL17-expressing tumor cells increased immature CD11b(+Gr1(+ myeloid-derived cells at tumor sites in mice and promoted CD31(+ tumor angiogenesis. Extensive chemotactic assays proved that CXCL17-responding cells were CD11b(+Gr1(highF4/80(- cells (≈ 90% with a neutrophil-like morphology in vitro. Although CXCL17 expression could not increase the number of CD11b(+Gr1(+ cells in tumor-burdened SCID mice or promote metastases of low metastatic colon cancer cells, the existence of CXCL17-responding myeloid-derived cells caused a striking enhancement of xenograft tumor formation. CONCLUSIONS/SIGNIFICANCE: These results suggest that aberrant expression of CXCL17 in tumor cells recruits immature myeloid-derived cells and promotes tumor progression through angiogenesis.

    Hydrogen sulfide, an endogenous signaling molecule, plays an important role in the physiology and pathophysiology of the cardiovascular system. Using a mouse model of myocardial infarction, we investigated the anti-inflammatory and anti-apoptotic effects of the H2S donor sodium hydrosulfide (NaHS). The results demonstrated that the administration of NaHS improved survival, preserved left ventricular function, limited infarct size, and improved H2S levels in cardiac tissue to attenuate the recruitment of CD11b+Gr-1+ myeloid cells and to regulate the Bax/Bcl-2 pathway. Furthermore, the cardioprotective effects of NaHS were enhanced by inhibiting the migration of CD11b+Gr-1+ myeloid cells from the spleen into the blood and by attenuating post-infarction inflammation. These observations suggest that the novel mechanism underlying the cardioprotective function of H2S is secondary to a combination of attenuation the recruitment of CD11b+Gr-1+ myeloid cells and regulation of the Bax/Bcl-2 apoptotic signaling.

Os tratamentos foram constituídos por diferentes tipos de grãos, não processados, sendo: grão de milho, grão de aveia branca, grão de aveia preta ou grão de arroz com casca. Os animais foram abatidos quando atingiram o peso vivo de abate pré-estabelecido de 32kg, que corresponde a 60% do peso adulto de suas mães. Cordeiros alimentados com dietas de alto grão de milho apresentam maiores consumos de matéria seca, matéria orgânica, proteína bruta, carboidratos totais e de nutrientes digestíveis totais, menor consumo de fibra em detergente neutro, melhor escore de condição corporal, ganho de peso e conversão alimentar, o que leva à redução do número de dias no confinamento necessários para atingir o peso de abate. Além disso, cordeiros terminados com o uso de dieta de alto grão à base de grão de milho proporcionam melhor resultado econômico quando comparados com cordeiros terminados com as demais dietas de alto grão utilizadas neste experimento. O uso de dietas de alto grão de milho, aveia branca, aveia preta ou arroz com casca para terminação de cordeiros em sistema de confinamento é uma alternativa viável do ponto de vista produtivo. Porém, o uso de grão de milho proporciona melhores resultados produtivos e econômicos.

    Full Text Available O objetivo deste trabalho foi avaliar o efeito da relação de intermitência e da temperatura do ar de secagem na qualidade de grãos de aveia, armazenados em sistema convencional por 12 meses. Aveia, cultivar "UPF 18", da safra agrícola 2002/2003 foi submetida à secagem em três temperaturas (65°C, 85°C e 105°C e a três relações de intermitência (1:2,5, 1:3,7 e 1:5, através de um delineamento composto central rotacional, sendo avaliadas a composição química centesimal, a umidade de armazenamento e a contaminação fúngica dos grãos. Os dados foram submetidos à análise de variância e de regressão polinomial. A secagem intermitente, com temperatura do ar até 65°C, é um método eficiente para a conservação dos parâmetros biológicos de grãos de aveia branca. Embora diminuam a incidência de contaminação fúngica, temperaturas da massa de grãos acima de 45°C durante a secagem provocam redução da qualidade dos grãos de aveia.This research was aimed at evaluating the effect of the relationship intermittence and the temperature of the drying air on the physiological and technological quality of oat grains stored in a conventional system for 12 months. Oat, UPF 18 cultivar, harvest in 2002/2003 was submitted to drying at three temperatures (65°C, 85°C, 110°C and three intermittent relations (1:2,5, 1:3,7, 1:5, following a central composite design. After the treatments, it was evaluated the centesimal chemical composition, moisture and fungi contamination of oat grains. The results were analysed through analysis of variance and polynomial regression. The intermittent drying with air temperature until 65°C is an efficient method in preserving the biological parameters of the white oat grains. Although it reduces the fungi contamination occurrence, the mass grain temperature over 45°C during the drying reduces the quality of oat grains.

    Full Text Available O objetivo deste trabalho foi estudar a cinética de secagem em camada fina dos grãos de guandu submetidos a diversas condições de secagem, por meio de diferentes modelos matemáticos. Com o modelo de Fick, determinou-se a difusividade efetiva e a energia de ativação. Para tal, foram utilizadas amostras de 200 g de grãos de guandu com teor de água inicial de 25% (b.u., as quais foram secas em um secador experimental de leito fixo, ajustado para operar nas temperaturas de 40, 50, 60 e 70 °C e velocidade do ar de secagem a 1,0 m s–1. A secagem, para cada temperatura, foi realizada até o teor de água de equilíbrio dinâmico. Os valores médios da temperatura e da umidade relativa do ar ambiente foram, respectivamente, 26 °C e 68%. A difusividade efetiva do produto foi determinada, para cada temperatura, pressupondo o grão de guandu como uma esfera de igual volume do grão. A difusividade efetiva do produto em função da temperatura foi expressa por uma equação semelhante à proposta por Arrhenius. A análise dos resultados possibilita concluir que as equações de Cavalcanti Mata com seis constantes e Midilli et al. representam, de forma satisfatória, o processo de secagem em todas as condições estudadas; e que utilizando o modelo de Fick a difusividade dos grãos de guandu variou de 2,1x10–10 até 6,8x10-10 m2.s–1 para as temperaturas entre 40 e 70 °C, respectivamente; e a energia de ativação obtida é igual a 34,51kJ.mol–1.

Su evidente atractivo entre los lectores ha hecho que algunos padres, educadores y profesionales del ámbito de la promoción de la lectura se plantearan el por qué de dicha afición, llegando a conclusiones erróneas como la creencia de que se trata de una lectura menor, dirigida esencialmente a la pura distracción de quien los lee. El manga, en concreto, es el género dentro del cómic que más se consume en occidente. Se ha convertido en un fructífero producto de mercado que deriva en videojuegos, series de televisión, películas de cine… Su gran acogida entre el público infantil y juvenil preocupa a mediadores por la supuesta carga violenta y sexual y la baja calidad literaria de sus obras. El presente propuesta tratará de deshacer algunos tópicos en relación con la concepción errónea la historieta nipona, a partir del estudio de un corpus de obras creadas por autores japoneses y europeos que quieren aportar un cómic de calidad tanto en su forma como en el contenido, abriendo así las puertas a nuevas investigaciones de gran interés. La Novelle manga es un nuevo género dentro del cómic nipón que aúna las estrategias comunicativas más destacables de las novelas gráficas japonesas, el valor estético del cómic francés y la sencillez y el tono de las películas de cine francés dentro de la Nouvelle Vague para crear un cómic que narra historias cotidianas de gran valor literario y estético, muy recomendable para lectores juveniles y adultos.

A substituição do grão de milho pelo grão de milheto e as fontes de volumoso não influenciaram o consumo de nutrientes. Entretanto, a utilização da silagem de capim-elefante aumentou o consumo de fibra em detergente ácido e reduziu o consumo de amido em comparação às dietas contendo silagem de milho. Não houve efeito da substituição do grão de milho pelo grão de milheto sobre a digestibilidade de matéria seca, matéria orgânica, proteína bruta, fibra em detergente neutro e fibra em detergente ácido. Contudo, houve aumento da digestibilidade do extrato etéreo, e os maiores valores foram observados para as dietas contendo 50 e 100% de grão de milheto em relação às dietas contendo 100% de grão de milho, independentemente da fonte de volumoso. A digestibilidade do amido também aumentou com a substituição do grão de milho pelo grão de milheto. A fonte de volumoso influenciou a digestibilidade da fibra em detergente neutro e da fibra em detergente ácido, que aumentou com a utilização da silagem de capim-elefante. A substituição do grão de milho pelo grão de milheto na dieta reduz a concentração ruminal de amônia sem alterar a concentração de acetato, propionato, ácidos graxos voláteis totais e o pH ruminal. A utilização de silagem de capim-elefante aumenta a concentração ruminal de acetato e a relação acetato:propionato.The objective of this

Em trabalhos anteriores, foi observado que as folhas novas de plantas jovens de grápia apresentaram sintomas visuais indicativos de deficiência de Fe na presença de doses crescentes de P. O presente trabalho teve como objetivo caracterizar os efeitos da interação da adubação de P e Fe no balanço nutricional e no crescimento de plantas jovens de grápia cultivadas num ARGISSOLO VERMELHO Distrófico arênico, sob condições de casa de vegetação. Os tratamentos consistiram de uma combinação bifatorial (2x3 completa, com dois níveis de adubação de fósforo (60 e 180 mg kg-1 e três níveis de ferro (0, 6 e 12 mg kg-1; além disso, realizou-se adubação complementar de N, K, Ca e Mg em todos tratamentos. A análise de crescimento das plantas foi realizada mensalmente, considerando a altura de planta, diâmetro do caule e número de folhas por planta. Aos 150 dias após a emergência das plantas, avaliaram-se ainda a massa seca de raízes, do caule, das folhas e total da planta, comprimento das raízes, comprimento radicular específico, número de folhas caídas, relação entre a massa seca de raízes e da parte aérea e a concentração de P, Fe, Cu e Zn nos tecidos da planta. A relação de concentração entre o P e os micronutrientes Fe, Cu e Zn é mais apropriada na avaliação do estado nutricional da grápia que a análise da concentração absoluta desses elementos nos tecidos. A alta disponibilidade de P no solo causou deficiência de Fe, Cu e Zn nas plantas de grápia. O aumento da disponibilidade de Fe, ocasionado pela adubação desse elemento, ou pela diminuição do pH do solo, induzida pela adubação com outros nutrientes, provocou decréscimo nas concentrações de Cu e Zn nas raízes. Na presença de 180 mg de P kg-1 de solo, a aplicação de 12 mg de Fe kg-1 de

    Full Text Available Por meio de um trabalho multidisciplinar entre Engenheiros e Dentistas, foram estudados oito diferentes tipos de grãos abrasivos de diamantes para a fabricação de pontas adiamantadas e/ou rebolos de pequeno diâmetro. Verificou-se qual o grão mais adequado para ser empregado nas pontas, as quais são utilizadas em equipamentos que possuem um pequeno torque disponível. Uma metodologia de experimentação para avaliação da capacidade de corte destas ferramentas foi desenvolvida, utilizando-se o vidro como material a ser desgastado. Como resultados, observou-se que a estrutura e a friabilidade do grão de diamante afetam diretamente a capacidade de corte das pontas adiamantadas. Desta forma, o melhor tipo de diamante foi aquele que apresentou, ao mesmo tempo, as melhores condições de remoção de material e o menor preço.This paper presents a multi-area research involving Dentists and Engineers, in which eight different types of diamond abrasive grains, which are used in dental burs (small diameter grinding wheels were tested. The most appropriated grain to be used in burs was evaluated. These burs are used in dental equipment characterized by low torque and low spindle rotation. A test methodology was developed in order to evaluate the cutting capacity of these burs, using glass as a machining material. The results show that it was possible to verify that the grain structure and friability were the properties that affect the cutting capacity. Consequently, the best diamond grain is the one that presented, simultaneously, the best material removal conditions and the lowest price.

    We are using a systemic plague model to identify the cells and pathways that are undermined by the virulence protein YopM of the plague bacterium Yersinia pestis. In this study, we pursued previous findings that Gr1(+) cells are required to selectively limit growth of ΔyopM Y. pestis and that CD11b(+) cells other than polymorphonuclear leukocytes (PMNs) are selectively lost in spleens infected with parent Y. pestis. When PMNs were ablated from mice, ΔyopM Y. pestis grew as well as the parent strain in liver but not in spleen, showing that these cells are critical for controlling growth of the mutant in liver but not spleen. In mice lacking expression of the chemokine receptor CCR2, wild-type growth was restored to ΔyopM Y. pestis in both organs. In spleen, the Gr1(+) cells differentially recruited by parent and ΔyopM Y. pestis infections were CCR2(+) Gr1(+) CD11b(+) CD11c(Lo-Int) MAC3(+) iNOS(+) (inducible nitric oxide synthase-positive) inflammatory dendritic cells (iDCs), and their recruitment to spleen from blood was blocked when YopM was present in the infecting strain. Consistent with influx of iDCs being affected by YopM in spleen, the growth defect of the ΔyopM mutant was relieved by the parent Y. pestis strain in a coinfection assay in which the parent strain could affect the fate of the mutant in trans. In a mouse model of bubonic plague, CCR2 also was shown to be required for ΔyopM Y. pestis to show wild-type growth in skin. The data imply that YopM's pathogenic effect indirectly undermines signaling through CCR2. We propose a model for how YopM exerts its different effects in liver and spleen.

    May-Grünwald-Giemsa (MGG) stain is a Romanowsky-type, polychromatic stain as those of Giemsa, Leishman and Wright. Apart being the reference method of haematology, it has become a routine stain of diagnostic cytopathology for the study of air-dried preparations (lymph node imprints, centrifuged body fluids and fine needle aspirations). In the context of their actions of promoting the principles of quality assurance in cytopathology, the French Association for Quality Assurance in Anatomic and Cytologic Pathology (AFAQAP) and the French Society of Clinical Cytology (SFCC) conducted a proficiency test on MGG stain in 2013. Results from the test, together with the review of literature data allow pre-analytical and analytical steps of MGG stain to be updated. Recommendations include rapid air-drying of cell preparations/imprints, fixation using either methanol or May-Grünwald alone for 3-10minutes, two-step staining: 50% May-Grünwald in buffer pH 6.8 v/v for 3-5minutes, followed by 10% buffered Giemsa solution for 10-30minutes, and running water for 1-3minutes. Quality evaluation must be performed on red blood cells (RBCs) and leukocytes, not on tumour cells. Under correct pH conditions, RBCs must appear pink-orange (acidophilic) or buff-coloured, neither green nor blue. Leukocyte cytoplasm must be almost transparent, with clearly delineated granules. However, staining may vary somewhat and testing is recommended for automated methods (slide stainers) which remain the standard for reproducibility. Though MGG stain remains the reference stain, Diff-Quik(®) stain can be used for the rapid evaluation of cell samples. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    This study investigates the antagonistic effects of the probiotic strains Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 against vulvovaginal candidiasis (VVC)-causing Candida glabrata. Growth inhibitory activities of Lact. rhamnosus GR-1 and Lact. reuteri RC-14 strains against C. glabrata were demonstrated using a spot overlay assay and a plate-based microtitre assay. In addition, these probiotic lactobacilli strains also exhibited potent candidacidal activity against C. glabrata, as demonstrated by a LIVE/DEAD yeast viability assay performed using confocal laser scanning microscopy. The metabolic activities of all C. glabrata strains were completely shut down in response to the challenges by the probiotic lactobacilli strains. In addition, both probiotic lactobacilli strains exhibited strong autoaggregation and coaggregation phenotypes in the presence of C. glabrata, which indicate that these lactobacilli strains may exert their probiotic effects through the formation of aggregates and, thus the consequent prevention of colonization by C. glabrata. Probiotic Lact. rhamnosus GR-1 and Lact. reuteri RC-14 strains exhibited potent antagonistic activities against all of the tested C. glabrata strains. These lactobacilli exhibited antifungal effects, including those attributed to their aggregation abilities, and their presence caused the cessation of growth and eventual cell death of C. glabrata. This is the first study to report on the antagonistic effects of these probiotic lactobacilli strains against the non-Candida albicans Candida (NCAC) species C. glabrata. © 2015 The Authors published by John Wiley & Sons Ltd on behalf of Society for Applied Microbiology.

    Full Text Available Este artículo se compone de dos partes. En la primera se identifican las tendencias que enmarcan las transformaciones ocurridas en la industria de artes gráficas, imprentas y editoriales en las dos últimas décadas del siglo XX. Entre estas se destacan la conformación de grupos empresariales en medio de un notable impacto del cambio técnico impulsado por la digitalización de la producción gráfica y una acelerada convergencia tecnológica que propicia la integración de la industria gráfica con las de la información, la comunicación y el entretenimiento. A causa de ello esta industria está inmersa en una reconfiguración que afecta su morfología. En la segunda parte, se intentan dilucidar los retos analíticos que se desprenden de las transformaciones detectadas, y se plantea que para interpretar la dinámica de las transformaciones empresariales detectadas y el papel vital que en ellas juega el cambio técnico se pueden integrar los aportes de la teoría de los costos de transacción, la perspectiva evolutiva del cambio técnico y el enfoque de los recursos y las capacidades. Se sugiere, igualmente, que síntesis analíticas como la propuesta reclaman una apertura disciplinaria concordante con los desafíos que abren transformaciones empresariales como la descrita en la primera parte del artículo y que poco se han estudiado en el país.

    The exposure rates from natural background radiation - including terrestrial gamma radiation and the ionizing component of cosmic rays - were measured for the first time in the city of khartoum using two types of TLD materials: LiF:Mg,Cu,P (GR-200) and CaSo 4 :Mn TLD chips. Measurements were performed at two sites simultaneously, one site was selected on land in the vicinity of the Sudan Atomic Energy Commission, for the purposes of the measurement of the total exposure rate outdoors, while the other site was located on a buoy anchored in the Blue Nile, and was selected to measure the exposure rate due to the ionizing component of cosmic rays. The investigations were conducted for periods of between 5 and 28 days. Calibration was performed on a selected number of dosimeters to determine the exposure rates at each site. The exposure rates from the ionizing component of cosmic rays in Khartoum were found to be respectively 33 nGy.h -1 and 30 nGy.h -1 , in the measurements performed within the scope of this work using GR-200 and CaSo 4 :Mn dosimeters, while the total values for exposure on land were found to be 45 nGy.h -1 and 42 nGy.h -1 respectively. These values compare reasonably well with other national averages reported in the UNSCEAR publication. The comparison of the results for the two dosimetric materials demonstrates both the sensitivity and suitability of GR-200 for the purposes of environmental monitoring (orig.)

    Full Text Available This article analyzes the phenomenon of lobbying as a form of communication of public authorities, business and socio-political actors. The article based on the evaluation results of a poll presents a generalized picture of the functioning of lobbyists on the political landscape, disclosed the specifics of the use of GR-tech lobbyists at national and supranational level in the European Union. Analyzed data from a sociological study of the impact of information on the effectiveness of management decision-making by lobbyists in Eastern Europe and the Baltic States, evaluate the effectiveness of various political aktor-lobbyists. The system of power in the EU multi-level, lobbying is carried out with a strong competition between different interest groups. By the way, the Russian business poorly informed about the possibilities and mechanisms to defend their interests at EU level and does not use this tool. Institutes of the EU authorities, is the center of the work of lobbyists are the European Council, the Council of Ministers, the European Parliament and the European Commission. With regard to professional lobbying transparency of the process, about one in four out of five respondents said that business, trade associations and professional organizations are transparent in their approach to the process of political and administrative lobbying, while only one in five said this factor in relation to companies. Respondents clearly express support for democratization and openness of the political process, which is transparent to the various representatives and interest groups, and the lobbyists are expected to be open about their interests represented. It is not clear defined interests or lack of transparency called the most negative aspect of lobbying. Thus, many experts noted that the successful lobbying can change the state of the social environment and the socio-political relations. When both unsuccessful lobbying ends

  3. SpaGrOW—A Derivative-Free Optimization Scheme for Intermolecular Force Field Parameters Based on Sparse Grid Methods

    Directory of Open Access Journals (Sweden)

    2013-09-01

    Full Text Available Molecular modeling is an important subdomain in the field of computational modeling, regarding both scientific and industrial applications. This is because computer simulations on a molecular level are a virtuous instrument to study the impact of microscopic on macroscopic phenomena. Accurate molecular models are indispensable for such simulations in order to predict physical target observables, like density, pressure, diffusion coefficients or energetic properties, quantitatively over a wide range of temperatures. Thereby, molecular interactions are described mathematically by force fields. The mathematical description includes parameters for both intramolecular and intermolecular interactions. While intramolecular force field parameters can be determined by quantum mechanics, the parameterization of the intermolecular part is often tedious. Recently, an empirical procedure, based on the minimization of a loss function between simulated and experimental physical properties, was published by the authors. Thereby, efficient gradient-based numerical optimization algorithms were used. However, empirical force field optimization is inhibited by the two following central issues appearing in molecular simulations: firstly, they are extremely time-consuming, even on modern and high-performance computer clusters, and secondly, simulation data is affected by statistical noise. The latter provokes the fact that an accurate computation of gradients or Hessians is nearly impossible close to a local or global minimum, mainly because the loss function is flat. Therefore, the question arises of whether to apply a derivative-free method approximating the loss function by an appropriate model function. In this paper, a new Sparse Grid-based Optimization Workflow (SpaGrOW is presented, which accomplishes this task robustly and, at the same time, keeps the number of time-consuming simulations relatively small. This is achieved by an efficient sampling procedure

  8. Adaptabilidade na produção de massa verde e grãos de genótipos de milho no Tocantins

    Directory of Open Access Journals (Sweden)

    Edmar Vinícius de Carvalho

    Full Text Available Condições distintas de cultivo fazem com que a resposta dos genótipos seja diferente em cada situação. Para amenizar o efeito desta interação são realizadas análises de adaptabilidade e estabilidade, que auxiliam na escolha dos genótipos. Porém, muitas vezes, um genótipo apresenta diversas finalidades, causando problemas ao agricultor em algumas situações e, o uso de genótipos específicos, poderia ser uma solução. O objetivo desta pesquisa foi estudar a adaptabilidade e estabilidade de genótipos de milho na região Centro-Sul do Estado do Tocantins, e classificá-los, quanto a tendência da finalidade produtiva: grãos ou massa verde. Foram realizados oito experimentos em dois municípios do Tocantins na entressafra 2010 e na safra 2010/2011, sendo avaliados 16 genótipos de milho. Avaliou-se a massa verde total da planta e a produção de grãos (em g planta-1, as quais foram usadas na análise de adaptabilidade e estabilidade e, posteriormente buscou-se classificar a tendência da finalidade produtiva dos genótipos. Os genótipos P09, P12, P10, H02 e H01 apresentaram classificação do coeficiente de regressão superior na produção de grãos em relação à massa verde total da planta, acontecendo o contrário com os genótipos P02 e P01. O genótipo H01, quanto à produção de grãos, foi adaptado a ambientes favoráveis e apresentou tendência da finalidade produtiva para esta característica. Ao contrário dos genótipos P08 e P02, que foram adaptados a ambos ambientes e a ambientes favoráveis, respectivamente, quanto à massa verde total da planta e, obtiveram tendência da finalidade produtiva para esta característica.

    In this paper, we establish a link between the Szász-Durrmeyer type operators and multiple Appell polynomials. We study a quantitative-Voronovskaya type theorem in terms of weighted modulus of smoothness using sixth order central moment and Grüss-Voronovskaya type theorem. We also establish a local approximation theorem by means of the Steklov means in terms of the first and the second order modulus of continuity and Voronovskaya type asymtotic theorem. Further, we discuss the degree of approximation by means of the weighted spaces. Lastly, we find the rate of approximation of functions having a derivative of bounded variation.

    In response to the Fukushima Daiichi nuclear power plant accident, the NRC conducted an analysis and issued recommendations to improve the safety of the nuclear reactors. These include strengthening and integrating emergency response capabilities and emphasizing periodic staff training, the performance of simulation exercises. As a tool to observe these recommendations, the Graphic Console was developed for Analysis of Severe Accidents, Visualization of OEs, NAEs and calculation of the source term for nuclear power plant of Laguna Verde (NPP-LV ; CoGrAAS). The CoGrAAS is a computer system that displays in an integrated, graphic and dynamic way the information of a catalog of previously simulated accident scenarios. Has core mimics, vessel, primary containment and safety systems, trend graph of thermodynamic and radiological variables and the emergency procedures (OEs), chronological list of events, windows with detailed information for the dry-well, among others. The use of CoGrAAS allows that staff to understand and become familiar with the thermo-hydraulic progression of actual scenarios that exceed the design basis including those with core damage as severe accidents. The system enables personnel to develop an integral vision of the scenarios during the exercises and drills by observing and analyzing the evolution of the main reactor, core and primary containment variables, the response of emergency systems and the influence of that progression on OEs and the emergency action levels (NAEs). The CoGrAAS allows o observe the radiological variables and obtain the source term, to make the projection of doses, at any time within the scenario evolution. Thus, not only can the phenomenology of severe accidents be analyzed and understood, it is also possible to exercise, verify and evaluate the performance of critical tasks in the application of procedures, guidelines and emergency management plans.

Esta investigación de corte socioepistemológico muestra tres casos ilustrativos sobre cómo esta comunidad académico-científica usa gráficas cartesianas. Se evidencian significados propios que provienen del uso de conocimiento matemático y que se integran en una significación mayor con una riqueza en la articulación de nociones como pendiente de rectas y puntos de intersección. El objetivo es mostrar la factibilidad de un cambio didáctico de los objetos hacia las prácticas, ya que estas favorecen un desarrollo intencional de usos del conocimiento matemático, propuesta que puede permear a lo largo del contexto escolar como una herramienta para el desarrollo de pensamiento matemático.

    Full Text Available http://dx.doi.org/10.5007/1807-9288.2016v12n1p38 Este ensaio teórico-visual consiste em uma análise teórica e uma intervenção gráfica sobre o poema Homeóstato #04 da série Homeóstatos criada pelo poeta português José-Alberto Marques. A análise teórica surge de uma aproximação entre o poema e o conceito de Autopoiesis formulado por Humberto Maturana e Francisco Varela na década de 1970. A intervenção gráfica inspira-se na sugestão da forma poética desenhada pelo poeta digital brasileiro, André Vallias em seu poema “Nous n'avons pas compris Descartes” concebido em 1991.

  16. Produção gráfica humorística, imprensa esportiva e estereótipo: as narrativas de Maciota, na revista Placar

    Directory of Open Access Journals (Sweden)

    Ana Cristina Carmelino

    Full Text Available Resumo O objetivo deste artigo é analisar traços estereotípicos associados à identidade brasileira, a partir de produções gráficas de humor publicadas na imprensa esportiva brasileira. Criadas por Paulo Paiva e publicadas na revista esportiva Placar, as narrativas do personagem Maciota foram pouco estudadas no país. As histórias ficcionais apresentam situações vividas por um antiatleta no contexto do futebol. Considera-se que certos traços estereotípicos tanto podem auxiliar na produção do humor e na consolidação do antiatleta quanto podem reforçar a construção de uma das identidades brasileiras: a malandragem. Dada a natureza do estudo, a fundamentação teórica estabelece um diálogo interdisciplinar entre as áreas da imprensa esportiva, do humor gráfico e da análise do discurso. O corpus de análise compreende 140 histórias sobre o personagem, publicadas na revista Placar de 1980 a 1983.

    In the present study, poly(sodium 4-styrenesulfonate) (PSS) functionalized graphene (GR) was synthesised via a simple one-step chemical reduction of exfoliated graphite oxides in the presence of PSS. Characterisation of as-made nanocomposite using Fourier transform infrared spectroscopy (FT-IR) and ultraviolet and visible spectroscopy (UV-vis) clearly demonstrate the successful attachment of PSS to graphene sheets. A novel clenbuterol (CLB) electrochemical sensor was fabricated based on isopropanol-Nafion-PSS-GR composite film modified glassy carbon electrode. In the Britton-Robinson buffer (pH 1.2), the sensor exhibited superior electrocatalytic activity towards the oxidation of CLB. Applying linear sweep voltammetry, a good linear relationship of the oxidation peak current with respect to concentrations of CLB cross the range of 7.5 × 10(-8)-2.5 × 10(-5)mol L(-1) and a detection limit of 2.2 × 10(-8) mol L(-1) were achieved. The proposed method was successfully applied for the determination of CLB in pork. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available O objetivo do presente trabalho foi ajustar o modelo da difusão líquida às curvas de secagem do trigo considerando a contração volumétrica do grão e determinar os coeficientes de difusão para diversas condições controladas de temperatura e umidade relativa. Foram utilizados grãos de trigo, com teor de água inicial de 0,32 b.s. A secagem do produto foi realizada para diferentes condições controladas de temperatura, entre 25 e 55 °C, e umidade relativa de 55 ± 1%. A contração volumétrica do grão foi determinada pela relação entre o volume para cada teor de água e o volume inicial. Com base nos resultados obtidos, conclui-se que o modelo da difusão líquida representa satisfatoriamente a cinética de secagem do trigo para as diversas condições de ar experimentadas, não tendo sido considerado o efeito da contração volumétrica dos grãos. O coeficiente de difusão aumenta com a elevação da temperatura do ar, apresentando valores de 8,6775 x 10-11 e 42,8743 x 10-11 m².s-1 para a faixa de temperatura estudada e considerando a contração volumétrica. A relação entre o coeficiente de difusão e a temperatura pode ser descrita pela expressão de Arrhenius, que apresenta uma energia de ativação para a difusão líquida nos grãos de trigo de 42,00 kJ.mol-1.The aim of this work was to adjust the liquid diffusion model to the wheat drying curves considering the shrinkage of the grains and to determine the diffusion coefficients under different air conditions. Rough rice with 0.32 (d.b. moisture content was used in this experiment. The drying procedure was done under different controlled temperatures of 25 to 55 °C with the drying air relative humidity of 55 ± 1%. The shrinkage of the grains was determined by the ratio between the volume of each moisture content and the initial volume. Based on the results, it can be concluded that the liquid diffusion model represents the wheat drying kinetics satisfactorily for

    Full Text Available Os objetivos neste estudo foram quantificar os efeitos da desfolhação resultante de diferentes períodos de pastejo em aveia branca (Avena sativa L., avaliar os potenciais forrageiro e granífero do cultivar FAPA 2 e determinar o período máximo de permanência dos animais em pastejo para possibilitar colheita de forragem sem afetar a produção de grãos. Os tratamentos (sem pastejo, 1, 2, 3, 4, 5, 6, 7 e 8 semanas de pastejo foram distribuídos em delineamento experimental de blocos ao acaso, com três repetições, em subparcelas, nas quais foram avaliados os períodos de pastejo. O cultivar de aveia branca avaliado demonstrou adequada recuperação à desfolhação para produção de altas quantidades de matéria seca, desde que a duração de pastejo não ultrapasse quatro semanas. Em pastejos prolongados (cinco, seis, sete e oito semanas, ocorre queda na produção de matéria seca e lenta recuperação de área foliar. O aumento no rendimento de grãos de aveia branca ocorre em períodos de 1 a 4 semanas de pastejo, em decorrência da redução do acamamento e da menor altura do meristema apical. Em desfolhações de 5 a 8 semanas de pastejo, a redução no rendimento de grãos acompanha o declínio do número de espigas por área, de espiguetas por espiga e de grãos por espiga. O pastejo controlado até quatro semanas estimula a produção de matéria seca e permite a produção de grãos, além de promover oportunidade para produção animal, demonstrando a alta aptidão desse cultivar ao sistema de duplo propósito.To quantify defoliation effects resulting from several grazing periods with cattle on white oat (Avena sativa L. an experiment was run at Experimental Station of Fundação Agrária de Pesquisa Agropecuária in Guarapuava, Paraná State, Brazil, from April to November of 1999. The specific objectives were to evaluate potential forage and grain yield of white oat cv. FAPA 2 after different grazing periods as well as to

    Full Text Available Verificar a influência do teor de água nos valores da força máxima de compressão para deformações fixas e determinar o módulo proporcional de deformidade de grãos de feijão submetidos a compressão em três diferentes posições, foram os principais objetivos que estimularam o presente trabalho. Para isto, utilizaram-se grãos de feijão com teores de água variando de 0,13 a 0,45 (b.s. comprimidos uniaxicialmente, entre duas placas paralelas, na direção de suas três dimensões essenciais. A partir dos resultados obtidos, conclui-se que a força de compressão necessária para deformar o feijão diminui com o aumento do teor de água, sendo maior para a direção perpendicular à divisão dos cotilédones (posição natural de repouso. O módulo proporcional de deformidade aumenta com a redução do teor de água e da deformação do produto, obtendo-se valores para a faixa de umidade estudada, entre 1,7 x 10(7 a 71,3 x 10(7 Pa, dependendo da posição do grão.This work aims to determine the effect of soybean grain moisture content upon the maximum compression force values for fixed deformations and to determine the proportional deformity modulus under different compression positions. Edible beans with 0.45 to 0.13 (d.b. moisture content were compressed uniaxialy between two parallel plates towards their three main axes. From the results it was concluded that the compression force decreased with moisture content increase, and the highest value corresponded to the direction perpendicular to cotyledon division (repose position. The proportional deformity modulus increases with the reduction of moisture content and with the deformation of the product, presenting values, for the studied moisture content, between 1.7 x 10(7 to 71.3 x 10(7 Pa, depending on grain position.
