    Full Text Available Normal 0 21 MicrosoftInternetExplorer4 Este estudo teve como objetivo acompanhar a maturação fisiológica, seus parâmetros indicadores e identificar o momento adequado para a coleta de sementes de Eugenia uniflora, avaliando também a incidência de fungos em frutos e sementes. A pesquisa foi realizada de agosto a outubro de 2004 em Santa Maria, RS. A coleta dos frutos e sementes ocorreu semanalmente, partindo de três árvores matrizes, com início aos 7 dias após a antese (DAA e término aos 77 DAA. As variáveis observadas foram: altura, diâmetro, peso verde e sanidade de frutos e sementes e teor de umidade, massa seca e germinação das sementes. Identificou-se que a época adequada para a coleta das sementes, no período e local de estudo, ocorreu entre 56 e 63 DAA, quando os frutos apresentavam coloração vermelha e as sementes elevada germinação. Nesse período, o tamanho e o peso de frutos e sementes atingiram seus valores máximos e o teor de umidade e matéria seca das sementes mostraram tendência à estabilização. Os gêneros fúngicos Cladosporium sp. e Alternaria sp.  apresentaram as maiores taxas de incidência nos frutos e nas sementes e podem influenciar o armazenamento e a germinação das sementes de mudas de Eugenia uniflora.

    This is the first report about the modifying antibiotic activity of Eugenia uniflora L. and Eugenia jambolanum L. In this study the ethanol extract of E. uniflora and E. jambolanum was tested for their antimicrobial activity against strains of Escherichia coli. The growth of the two strains of E. coli bacteria tested was not inhibited in a clinically relevant form by the extract. The minimal inhibitory concentration was >or=1,024 microg/mL for both strains of E. coli assayed. Synergism between this extract and gentamicin was demonstrated. In the same extract synergism was observed between chlorpromazine and kanamycin and between amikacin and tobramycin, indicating the involvement of an efflux system in the resistance to these aminoglycosides. It is therefore suggested that extracts from E. uniflora L. and E. jambolanum L. could be used as a source of plant-derived natural products with modifying antibiotic activity to gentamicin.

    Abstract A new section of Eugenia (Myrtaceae) is described, segregate from Eugenia sect. Phyllocalyx. Phylogenetic studies suggest that Eugenia sect. Phyllocalyx as traditionally delimited is paraphyletic. To maintain the monophyly of each of the sections in Eugenia s.l., we herein opt to circumscribe a new section and recognize six taxa in sect. Speciosae, which has a distribution mostly in southeastern Brazil and northern South America. Nomenclatural notes are made and a taxonomic key is provided for the species of the section.

    Full Text Available The wood anatomy of nine species of Eugenia (Myrtaceae native in Rio Grande do Sul State (Brazil is presently studied in order to identify diagnostic characters useful to identify genus and species. A great structural homogeneity was observed, reflecting the high number of shared anatomical features. None characteristic is exclusive to this taxonomic group. The value of axial parenchyma arrangement to species segregation is confirmed, as well as the frequency of pores and characteristics of rays. It is not possible to disprove, based on wood anatomy, the inclusion of Hexachlamys in Eugenia , as suggested by Landrum and Kawasaki (1997.

    Full Text Available O objetivo do estudo é analisar o que versam as produções científicas sobre eugenia, vinculando-as com aspectos bioéticos. Trata-se de uma revisão integrativa de literatura. Os dados foram coletados nas bases de dados Lilacs e SciELO, por meio dos descritores: eugenia, etnia e saúde, ética e bioética. Para a análise e posterior síntese dos artigos foi utilizada figura sinóptica. Verificou-se que a eugenia viola os direitos humanos, contradiz com o princípio da solidariedade e coloca em risco a diversidade humana. Conclui-se que houve déficit de artigos que abordem aspectos bioéticos vinculados à eugenia, assim, este estudo poderá contribuir para a reflexão sobre essa articulação.

    2009-01-01

    Objective: To estimate the hepatoprotective effects of the methanolic seed extract of Eugenia jambolana Lam. (Myrtaceae), in Wistar albino rats treated with carbon tetrachloride (CCl4). Materials and Methods: Liver damage in rats treated with CCl4 (1ml/kg/Bw, administered subcutaneously, on alternate days for one week) was studied by assessing parameters such as serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), acid phosphatase (ACP) and bilirubin (total and direct). The effect of co-administration of Eugenia jambolana Lam. (doses 100, 200 and 400 mg/kg p. o.) on the above parameters was investigated. These biochemical observations were supplemented by weight and histological examination of liver sections. Liv.52® was used as positive control. Data were analyzed by one way ANOVA, followed by Scheff's/Dunnett's test. Results: Administration of Eugenia jambolana Lam. (doses 100, 200 and 400 mg/kg p. o.) significantly prevented carbon tetrachloride induced elevation of serum SGOT, SGPT, ALP, ACP and bilirubin (total and direct) level. Histological examination of the liver section revealed hepatic regeneration, after administration of various doses of Eugenia jambolana Lam. The results were comparable to that of Liv.52®. Conclusion: The study suggests preventive action of Eugenia jambolana Lam. in carbon tetrachloride induced liver toxicity. Hepatic cell regeneration process was dose dependent. PMID:20177577

    Several species of Eugenia L. are used in folk medicine for the treatment of various diseases. Eugenia brasiliensis is used for the treatment of inflammatory diseases, whereas Eugenia. uniflora is used for the treatment of symptoms related to depression and mood disorders, and is used in Brazil by the Guarani Indians as a tonic stimulant. To investigate the antidepressant-like effect of hydroalcoholic extracts of different plant species of genus Eugenia and to characterize the participation of the monoaminergic systems in the mechanism of action of the specie that afforded the most prominent antidepressant-like efficacy. In the first set of experiments, the effects of hydroalcoholic extracts of Eugenia beaurepaireana, Eugenia brasiliensis, Eugenia catharinae, Eugenia umbelliflora and Eugenia uniflora and the antidepressant fluoxetine (positive control) administered acutely by p.o. route were evaluated in the tail suspension test (TST) and locomotor activity was assessed in the open-field test in mice. In the second set of experiments, the involvement of the monoaminergic systems in the antidepressant-like activity of Eugenia brasiliensis was evaluated by treating mice with several pharmacological agonists and antagonists. The effects of the combined administration of sub-effective doses of Eugenia brasiliensis and the antidepressants fluoxetine, imipramine and bupropion were also evaluated. The administration of the extracts from Eugenia brasiliensis, Eugenia catharinae and Eugenia umbelliflora, but not Eugenia beaurepaireana and Eugenia uniflora, exerted a significant antidepressant-like effect, without altering locomotor activity. The behavioral profile was similar to fluoxetine. Pre-treatment of mice with ketanserin, haloperidol, SCH23390, sulpiride, prazosin and yohimbine prevented the reduction of immobility time induced by Eugenia brasiliensis. Treatment with sub-effective doses of WAY100635, SKF38393, apomorphine, phenylephrine, but not clonidine, combined

    Full Text Available Hydrolysable tannins, total phenols and flavonoids in Eugenia uniflora leaves were monthly analysed for one year. The results were correlated with climate conditions (rainfall, humidity, cloudiness and mean temperature through chemometric methods. Principal component analysis revealed high levels of hydrolysable tannins in the rainy season, whereas flavonoids were mainly produced in the dry season. These facts suggest that climatic changes may be one of the factors affecting phenol levels in Eugenia uniflora.Taninos hidrolisáveis, fenóis totais e flavonóides presentes em folhas de Eugenia uniflora foram quantificados mensalmente durante um ano. Os resultados foram correlacionados com as condições climáticas (pluviosidade, umidade, nebulosidade e temperatura média através de métodos quimiométricos. Análise de componentes principais revelou a ocorrência de altos teores de taninos hidrolisáveis durante a estação de chuvas, enquanto os flavonóides foram produzidos principalmente na estação seca. Estes fatos sugerem que mudanças climáticas podem ser um dos fatores que afetam os níveis de fenóis em Eugenia uniflora.

    Full Text Available Leaf blight and defoliation of Eugenia stipitata Mc Vaugh and Eugenia patrisii Vahl, caused respectively by Cylindrocladium candelabrum (Calonectria scoparia and C. spathiphylli (Calonectria spathiphylli are reported in the state of Pará, Brazil. On both host species, the disease is characterized by dark brown lesions of different sizes and shapes. A whitish bright sporulation, resembling Cylindrocladium is observed on the necrotic lesions by using a stereomycroscope or a pocket lense (10-20 X. Under favorable conditions and depending on the level of infection, intense premature tree defoliation may also be found.Although the conidial germination and mycelial growth were higher at 25ºC for both species, C. candelabrum was more sensitive to the variation of temperature (10, 20, 30 and 40 ºC than C. spathiphylli. This is the first report of C. candelabrum and C. spathiphylli on Eugenia stipitata (araçá-boi and on Eugenia patrisii (ubaia-da-amazônia, respectively in Brazil.

    Comparative floral ontogeny represents a valuable tool to understand angiosperm evolution. Such an approach may elucidate subtle changes in development that discretely modify floral architecture and underlie reproductive lability in groups with superficial homogeneous morphology. This study presents a comparative survey of floral development in Eugenia (Myrtaceae), one of the largest genera of angiosperms, and shows how previously undocumented ontogenetic trends help to explain the evolution of its megadiversity in contrast to its apparent flower uniformity. Using scanning electron microscopy, selected steps of the floral ontogeny of a model species (Eugenia punicifolia) are described and compared with 20 further species representing all ten major clades in the Eugenia phylogenetic tree. Additional floral trait data are contrasted for correlation analysis and character reconstructions performed against the Myrtaceae phylogenetic tree. Eugenia flowers show similar organ arrangement patterns: radially symmetrical, (most commonly) tetramerous flowers with variable numbers of stamens and ovules. Despite a similar general organization, heterochrony is evident from size differences between tissues and structures at similar developmental stages. These differences underlie variable levels of investment in protection, subtle modifications to symmetry, herkogamic effects and independent androecium and gynoecium variation, producing a wide spectrum of floral display and contributing to fluctuations in fitness. During Eugenia's bud development, the hypanthium (as defined here) is completely covered by stamen primordia, unusual in other Myrtaceae. This is the likely plesiomorphic state for Myrteae and may have represented a key evolutionary novelty in the tribe. Floral evolution in Eugenia depends on heterochronic patterns rather than changes in complexity to promote flexibility in floral strategies. The successful early establishment of Myrteae, previously mainly linked to the

    One of the most robust findings in experimental economics is that individuals in one-shot ultimatum games reject unfair offers. Puzzlingly, rejections have been found robust to substantial increases in stakes. By using a novel experimental design that elicits frequent low offers and uses much...... larger stakes than in the literature, we are able to examine stakes' effects over ranges of data that are heretofore unexplored. Our main result is that proportionally equivalent offers are less likely to be rejected with high stakes. In fact, our paper is the first to present evidence that as stakes...

  18. Eugenia negativa/positiva: o suposto colapso da natureza em J. Habermas

    Heck, José Nicolau

    2006-01-01

    Full Text Available Há muito tempo o progresso científico provoca nossas convicções e ameaça deixar o discurso moral para trás. Mais recentemente, a polêmica em torno da persmissão ou proibição da eugenia negativa e positiva questiona nossa autocompreensão de natureza, moralidade e liberdade. O presente texto tem por objeto uma série de artigos de J. Habermas, convertidos posteriormente em livro, onde são expostos argumentos fortemente plausíveis em favor da tese da indisponibilidade da natureza humana no âmbito da eugenia positiva. Após contextuar o problema e mapeá-lo no horizonte filosófico, o trabalho apresenta a posição metafísica habermasiana, com destaque para a distinção entre eugenia negativa e positiva, e a confronta com os argumentos liberais dworkinianos acerca do tema. O artigo pleiteia a favor da tese de que a naturalidade humana consiste, desde os primórdios da espécie, em autocriação natural, de modo que cabe à moralidade e ao direito preencherem o vácuo do destino criado pela biotecnologia

  19. Raising the stakes: How students' motivation for mathematics associates with high- and low-stakes test achievement.

    2015-04-01

    This study uses data from an urban school district to examine the relation between students' motivational beliefs about mathematics and high- versus low-stakes math test performance. We use ordinary least squares and quantile regression analyses and find that the association between students' motivation and test performance differs based on the stakes of the exam. Students' math self-efficacy and performance avoidance goal orientation were the strongest predictors for both exams; however, students' math self-efficacy was more strongly related to achievement on the low-stakes exam. Students' motivational beliefs had a stronger association at the low-stakes exam proficiency cutoff than they did at the high-stakes passing cutoff. Lastly, the negative association between performance avoidance goals and high-stakes performance showed a decreasing trend across the achievement distribution, suggesting that performance avoidance goals are more detrimental for lower achieving students. These findings help parse out the ways motivation influences achievement under different stakes.

  20. Effect Of Various Substrates On Eudrilus eugeniae (Oligochaeta Production

    Mpoame, M.

    1994-01-01

    Full Text Available In order to assess the effects of substrate on Eudrilus eugeniae production, 360 worms were raised in plastic buckets containing manure either from cattle (BV, from sheep (CM, from rabbit (CL, and from chicken (FP. At the end of the experiment which lasted 4 months, worm productivity was estimated at 111.9 g/kg of substrate in CL, 86.3 g/kg in CM, and 33.0 g/kg in BV. Substrate FP was inadequate as worms escaped from it. In another trial aiming at determining some of E. Eugeniae's reproductive parameters, each of the 3 substrates BV, CL, and CM was distributed into 15 plastic half bottles and was inoculated with one cocoon. In the 3 substrates cocoon incubation time and growing period were estimated at 3 to 4 weeks and 6 to 7 weeks respectively. Cocoons were laid approximately a week after the pairing of worms. On the average, each worm laid 2 cocoons per week.

Eugenia uniflora L. and Eugenia malaccensis L. (Myrtaceae) have many folk uses in various countries. This current study was designed to quantify the polyphenols and flavonoids contents and evaluate the immunomodulatory, antioxidant, and cytotoxic potentials of fractions from E. uniflora L. and E. malaccensis L. It was observed that the polyphenol content was higher in ethyl acetate fractions. These fractions have high antioxidant potential. E. malaccensis L. seeds showed the largest DPPH radical scavenger capacity (EC50 = 22.62). The fractions of E. malaccensis L. leaves showed lower antioxidant capacity. The samples did not alter the profile of proinflammatory cytokines and nitric oxide release. The results indicate that species of the family Myrtaceae are rich in compounds with antioxidant capacity, which can help reduce the inflammatory response.

    Full Text Available Nicolas-Antoine Taunay, French landscape painter, produced also several portraits during his stay at the Rio de Janeiro Court. In this city, in 1816, he paints the queen Carlota Joaquina and all her daughters. In this group, two portraits have a very special way: the paintings still today catalogued as Maria Francisca and Maria Teresa, but probably being Maria Isabel and Maria Francisca de Assis - princesses that, in this year, left Brazil to marry the Spanish King Fernando VII, and his brother Carlos Maria Isidro de Bourbon. In this article, beyond to describe these portraits (and analyse the identities of the portrayed princesses, I analyse their functions in the Court society and the mains artists of this gender in Europe. I will discuss, as well, the hypothesis about the Taunay choices. In this sense, I will analyse the possible circulation of the typologies of portrait between Italy, Portugal, Spain and France, understanding these productions by Taunay and the functions occupied by these portraits in the political relations between Brazil and Europe.

    Full Text Available The use of substrates formulated with agro-industrial residues, such as coconut shell fiber, sawdust, and carbonized rice husk, is among the sustainable alternatives to decrease the production costs of seedlings of plant species. This study aimed to evaluate the use of various substrates for obtaining high quality Eugenia uniflora L. seedlings. The experiment was conducted at the Federal University of Pampa (UNIPAMPA – Campus in São Gabriel, Rio Grande do Sul, Brazil, by sowing directly into 200 cm3 polypropylene tubes, testing various substrates (50% commercial substrate Plantmax® + 50% rice husk; commercial substrate Plantmax®; 50% commercial substrate Plantmax® + 50% coconut shell fiber; and 50% commercial substrate Plantmax® + 50% sawdust. Every 3 days, the number of emerged seedlings was evaluated and, after 180 days, the following morphological features were analyzed: shoot height, stem diameter, number of leaves, root and total fresh weight, shoot, root, and total dry weight, and Dickson’s quality index. The results indicate that all substrates were suitable for Eugenia uniflora emergence, but that containing 50% commercial substrate Plantmax® + 50% sawdust provided a delay in the emergence of this Myrtaceae; also, substrates containing 50% commercial substrate Plantmax® + 50% husk rice and 50% commercial substrate Plantmax® + 50% coconut shell fiber showed to be satisfactory for the growth of Eugenia uniflora seedlings.

    The aim of this study was to evaluate the in vitro activity of dentifrices containing the hydroalcoholic extract of the ripe fruit of Eugenia uniflora L. (Surinam cherry) on Streptococcus oralis (ATCC 10557) and Lactobacillus casei (ATCC 7469). Five dentifrices were used: D1: containing hydroalcoholic extract of Eugenia uniflora L.; D2: containing fluoride and hydroalcoholic extract of Eugenia uniflora L.; D3: containing triclosan and hydroalcoholic extract of Eugenia uniflora L; D4: containing triclosan, fluoride and hydroalcoholic extract of Eugenia uniflora L.; D5: positive control (Colgate Total 12). To determine the antibacterial activity, the technique used was the minimum inhibitory concentration by the diffusion method in solid culture medium. At the concentration 0.05 g/mL, the best results were achieved with D1 (18 mm) and D4 (24 mm) on L.casei, and with D3 (19 mm) on S. oralis. The dentifrices D3 and D4 were found to have greater activity on the Streptococcus oralis, while D4 and D1 were found to have greater activity on Lactobaccilus casei. It is concluded that dentifrices with Eugenia uniflora L. have antimicrobial activity, suggesting that clinical trials should be conducted.

    This study describes the qualitative and quantitative chemical composition and evaluates the antibacterial activity of essential oil from Eugenia platysema leaves. Analysis by GC-FID and GC-MS allowed the identification of 22 compounds. Different from the other species of the Eugenia genus, the major compound found in the essential oil was the diterpene phytol (66.05%), being this the first report of the presence of this compound in the essential oils from Eugenia genus. The sesquiterpene elixene was the second most concentrated compound in the studied essential oil (9.16%). The essential oil from E. platysema was tested for its antibacterial activity against cell-walled bacteria and mollicute strains of clinical interest using the microdilution broth assay. The results showed that the essential oil of E. platysema was inactive until 1000 μg mL(-1) against tested bacteria.

    Comparative study was performed to evaluate the vermicomposting efficiency of two earthworm species Eisenia fetida, Eudrilus eugenia from the garden wastes, vegetable market wastes. Three different experimental works were conducted. For each experiment three plastic vermibins were used. Experiment (1) mentioned for control without earthworms. Experiment (2) bedded with Eudrilus eugenia, Experiment (3) comprised of bedding with Eisenia fetida. Pre composting was allowed for 10 days after that Eudrilus eugenia, Eisenia fetida were added in respective vermibins. The multiplication of earthworms in terms of number was calculated at the end of vermicomposting. The N, P, K value of the manure in each vermibin was estimated before and after the completion of the experiment. High N, P, K value was obtained in Experiment (2) and Experiment (3) compared to control. Among the solid wastes, the vegetable wastes were degraded quickly by Eudrilus eugenia and also it has the best quality of manure. Eudrilus eugenia was found to be efficient for quick degradation of both garden wastes and vegetable wastes. After manure production, field trials were conducted using different fertilizers to assess the manure quality in the growth and yield of tomato plants. Six types of experimental trial pots were prepared where one was kept as control and five others were treated with different category of fertilizers. The treatment pots (P3) showed better growth parameters (leaf numbers, stem diameter, plant height) than the rest of the trial.

    A laboratory study on the bioremediation of diesel contaminated soil with the earthworm Eudrilus eugeniae (Kingberg) was conducted. 5 ml of diesel was contaminated into soils in replicates and inoculated with E. eugeniae for 90 days. Physicochemical parameters, heavy metals and total petroleum hydrocarbons were analyzed using AAS. BTEX in contaminated soil and tissues of earthworms were determined with GC-FID. The activities of earthworms resulted in a decrease in pH (3.0 %), electrical conductivity (60.66 %), total nitrogen (47.37 %), chloride (60.66 %), total organic carbon (49.22 %), sulphate (60.59 %), nitrate (60.65 %), phosphate (60.80 %), sodium (60.65 %), potassium (60.67 %), calcium (60.67 %), magnesium (60.68 %), zinc (60.59 %), manganese (60.72 %), copper (60.68 %), nickel (60.58 %), cadmium (60.44 %), vanadium (61.19 %), chromium (53.60 %), lead (60.38 %), mercury (61.11 %), arsenic (80.85 %), TPH (84.99 %). Among the BTEX constituents, only benzene (8.35 %) was detected in soil at the end of the study. Earthworm tissue analysis showed varying levels of TPH (57.35 %), benzene (38.91 %), toluene (27.76 %), ethylbenzene (42.16 %) and xylene (09.62 %) in E. eugeniae at the end of the study. The study has shown that E. eugeniae could be applied as a possible bioremediator in diesel polluted soil.

    1975-01-01

    Isopach maps and structural contour maps of the eastern mare basins (30 deg N to 30 deg S; 0 deg to 100 deg E), constructed from measurements of partially buried craters, are presented and discussed. The data, which are sufficiently scattered to yield gross thickness variations, are restricted to shallow maria with less than 1500-2000 m of mare basalts. The average thickness of basalt in the irregular maria is between 200 and 400 m. Correlations between surface topography, basalt thickness, and basin floor structure are apparent in most of the basins that were studied. The mare surface is commonly depressed in regions of thick mare basalts; mare ridges are typically located in regions of pronounced thickness changes; and arcuate mare rilles are confined to thin mare basalts. Most surface structures are attributed to shallow stresses developed within the mare basalts during consolidation and volume reduction.

Nowadays, Maria is contracted at Ghent University (Belgium) where she is completing a post-doc. During the time I have known her, I have frequently been impressed by her exceptional capabilities to quickly learn new skills to develop and validate new liquid chromatographic procedures, and by her constant initiative to bring together innovative analytical methods. Maria has always adopted a positive, critical view and shows eagerness to better herself. Besides her exceptional knowledge in LC, she has a sound scientific background in capillary electrophoresis, GC, sample preparation and optimization procedures that allows her to complement her investigations and has resulted in significant papers in the analytical chemistry field. Our research group has greatly benefited from Maria's capabilities, as can be seen in recent publications in the Journal of Chromatography A, Talanta, Analytical and Bioanalytical Chemistry and other specialized journals that directly represent her work, mainly as corresponding author. It is extremely remarkable that she has published a review of her PhD results. Not everyone has the possibility to publish it. This is a clear sign of the high quality of her research. Compared to other fellows that I have supervised, Maria is undoubtedly the best one. I can, beyond all doubt, give a score of 10/10 to the quality of her research activity. Finally, I would personally like to add that she is an outstanding, serious, independent thinker who is always well informed about the topics she tackles. Maria is also very friendly, a good worker and always willing to help others, which has been a most positive characteristic

    The empress and queen Maria Theresa Habsburg-Lorraine (May 13th, 1917-November 29th, 1780) bore sixteen children in the marriage with the emperor Franz I Stepha and was famous as "mother-in-law of Europe". Her brother Leopold died immediately after he was born, her sister Amalia died in the cradle and Maria Ana died of perinatal complications at the birth of a dead infant in 1744. The famous hereditary facial dysmorphia of the "Hasburg jawe" wasn't noticed in Maria Theresa's surviving children. In October of 1738, after giving birth to her daughter Ana, a manual lysis of the placenta was performed due to the retained placenta and postpartal bleeding. In 1741 her daughter Carolina died, and in 1767 her daughter Josepha died of small pox. Her daughter Elizabeth remained deformed by the pock marks, and Maria Christina got a puerperal sepsis, but surprisingly, didn't die. Maria Antoinette ended under a guillotine in France, along with her husband Luis XVI. Maria Theresa's father, Karl VI died of the cholecystopankreatitis and peritonitis, and her husband and co-ruler most probably died of acute coronary incident in August 18th, 1765. After her husband's death she started suffering from depression with steady necrophile obsessions. Maria Theresa suffered from a chronical obstructional pulmonary disease (asthma), rehumatic syndromes, hypertension and anxiodepressive syndromes. In 1767 she had small pox. In November 11th 1780 she caught a cold which grew into a pneumonia with high fever. She died of cardiopulmonal dedompensation preceded by pneumonia and asthma.

    Eugenia sect. Phyllocalyx Nied. includes 14 species endemic to the Neotropics, mostly distributed in the Atlantic coastal forests of Brazil. Here the first comprehensive phylogenetic study of this group is presented, and this phylogeny is used as the basis to evaluate the recent infrageneric classification in Eugenia sensu lato (s.l.) to test the history of the evolution of traits in the group and test hypotheses associated with the history of this clade. A total of 42 taxa were sampled, of which 14 were Eugenia sect. Phyllocalyx for one nuclear (ribosomal internal transcribed spacer) and four plastid markers (psbA-trnH, rpl16, trnL-rpl32 and trnQ-rps16). The relationships were reconstructed based on Bayesian analysis and maximum likelihood. Additionally, ancestral area analysis and modelling methods were used to estimate species dispersal, comparing historically climatic stable (refuges) and unstable areas. Maximum likelihood and Bayesian inferences indicate that Eugenia sect. Phyllocalyx is paraphyletic and the two clades recovered are characterized by combinations of morphological characters. Phylogenetic relationships support a link between Cerrado and south-eastern species and a difference in the composition of species from north-eastern and south-eastern Atlantic forest. Refugia and stable areas identified within unstable areas suggest that these areas were important to maintain diversity in the Atlantic forest biodiversity hotspot. This study provides a robust phylogenetic framework to address important historical questions for Eugenia s.l. within an evolutionary context, supporting the need for better taxonomic study of one of the largest genera in the Neotropics. Furthermore, valuable insight is offered into diversification and biome shifts of plant species in the highly environmentally impacted Atlantic forest of South America. Evidence is presented that climate stability in the south-eastern Atlantic forest during the Quaternary contributed to the

    Background: Eugenia species are appreciated for their edible fruits and are known as having anticonvulsant, antimicrobial and insecticidal actions. Methods: The plant material was collected in the southeastern Pará state of Brazil and submitted to hydrodistillation. GC-MS analyzed the oils, and their antioxidant and cytotoxic activities were evaluated by the DPPH and MTT assays. Results: The main components identified in the Eugenia oils were 5-hydroxy- cis -calemene, (2 E ,6 E )-farnesol, (2 E ,6 Z )-farnesol, caryophylla-4(12),8(13)-dien-5α-ol-5β-ol, E -γ-bisabolene, β-bisabolene, germacrene D, and ishwarane. The oil of E. egensis showed the most significant antioxidant activity (216.5 ± 11.6 mg TE/mL), followed by the oils of E. flavescens (122.6 ± 6.8 mg TE/mL) and E. patrisii (111.2 ± 12.4 mg TE/mL). Eugenia oils were cytotoxic to HCT-116 (colon cancer) cells by the MTT assay, where the most active was the oil of E. polystachya (10.3 µg/mL), followed by the oils of E. flavescens (13.9 µg/mL) and E. patrisii (16.4 µg/mL). The oils of E. flavescens and E. patrisii showed the highest toxicity for MRC5 (human fibroblast) cells, with values of 14.0 µg/mL and 18.1 µg/mL, respectively. Conclusions: These results suggest that Eugenia oils could be tested in future studies for the treatment of colon cancer and oxidative stress management.

    Evidence of risk aversion in laboratory settings over small stakes leads to a priori implausible levels of risk aversion over large stakes under certain assumptions. One core assumption in standard statements of this calibration puzzle is that individuals define utility over terminal wealth......, and that terminal wealth is defined as the sum of extra-lab wealth and any wealth accumulated in the lab. This assumption is often used in Expected Utility Theory, as well as popular alternatives such as RankDependent Utility theory. Another core assumption is that the small-stakes risk aversion is observed over...... all levels of wealth, or over a “sufficiently large” range of wealth. Although this second assumption if often viewed as self-evident from the vast experimental literature showing risk aversion over laboratory stakes, it actually requires that lab wealth be varied for a given subject as one takes...

    It is widely accepted that knowing the composition and the orbital evolution of asteroids might help us to understand the process of formation of the Solar system. It is also known that asteroids can represent a threat to our planet. Such an important role has made space missions to asteroids a very popular topic in current astrodynamics and astronomy studies. Taking into account the increasing interest in space missions to asteroids, especially to multiple systems, we present a study that aims to characterize the stable and unstable regions around the triple system of asteroids (45) Eugenia. The goal is to characterize the unstable and stable regions of this system and to make a comparison with the system 2001 SN263, which is the target of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) mission. A new concept was used for mapping orbits, by considering the disturbance received by the spacecraft from all perturbing forces individually. This method has also been applied to (45) Eugenia. We present the stable and unstable regions for particles with relative inclination between 0° and 180°. We found that (45) Eugenia presents larger stable regions for both prograde and retrograde cases. This is mainly because the satellites of this system are small when compared to the primary body, and because they are not close to each other. We also present a comparison between these two triple systems, and we discuss how these results can guide us in the planning of future missions.

  17. French government to trim direct stake in Total

    International Nuclear Information System (INIS)

    Anon.

    1992-01-01

    This paper reports that the French government has decided to slash its direct stake in partly state owned oil company Total to 5% from 31.7%, a surprise move expected to raise 10 billion francs ($1.8 billion). At the same time, other state owned entities will be asked to boost their combined 2.2% stake in Total to 10%, leaving the government with a net 15% interest in Total vs. the current 34%. Initially, state owned insurance companies Groupe des Assurances Nationales and Assurances Generale de France will be asked to hike their stakes in Total, but others could be asked to join if needed to meet the 10% target. The government the its phase-down of participation in Total, established in 1924 to manage French interests in Iraq Petroleum Co., was prompted by the evolution of the oil context, which differs greatly from what had prompted a significant stake of the state in Total's capital

    2017-10-01

    A new piezoelectric actuator design, called "Stake" actuator, is proposed and demonstrated in this paper. As an example, the stake actuator is made of four d 32 -mode PZN-5.5%PT single crystals (SCs), each of 25 mm ( L ) ×8 mm ( W ) ×0.4 mm (T) in dimensions, bonded with the aid of polycarbonate edge guide-cum-stiffeners into a square-pipe configuration for improved bending and twisting strengths and capped with top and bottom pedestals made of 1.5-mm-thick anodized aluminum. The resultant stake actuator measured 9 mm ×9 mm ×28 mm. The hollow structure is a key design feature, which optimizes SC usage efficiency and lowers the overall cost of the actuator. The displacement-voltage responses, blocking forces, resonance characteristics of the fabricated stake actuator, as well as the load and temperature effects, are measured and discussed. Since d 32 is negative for [011]-poled SC, the "Stake" actuator contracts in the axial direction when a positive-polarity field is applied to the crystals. Biased drive is thus recommended when extensional displacement is desired. The SC stake actuator has negligible (0.13% when driven up to +300 V (i.e., 0.75 kV/mm), which is close to the rhombohedral-to-orthorhombic transformation field ( E RO ) of 0.85 kV/mm of the SC used. The stake actuator displays a stroke of [Formula: see text] (at +300 V) despite its small overall dimensions, and has a blocking force of 114 N. The SC d 32 stake actuator fabricated displays more than 30% larger axial strain than the state-of-the-art PZT stack actuators of comparable length as well as moderate blocking forces. Said actuators are thus ideal for applications when large displacements with simple open-loop control are preferred.

  4. RWE sells Nafta stake

    International Nuclear Information System (INIS)

    Janoska, J.

    2004-01-01

    At year-end 2000, state-owned Slovensky plynarensky priemysel (SPP) signed a Memorandum of Understanding that set the conditions for the German concern RWE to purchase a 40 % stake in Nafta Gbely. This partnership agreement was meant to grant RWE participation in the management of the gas storage operator, which is controlled by SPP, and allow RWE to increase the use of Nafta's capacities. But in the 3 years since then, these objectives were not met. RWE representatives were not appointed to the Nafta Board and not a single cubic meter of RWE gas was stored at Nafta. RWE denied that it was considering leaving Nafta. Control of Nafta and SPP gradually passed to RWE's major competitors. The attitude of RWE only changed last week, when it sold its stake in Nafta to Ruhrgas under favourable conditions. Although Ruhrgas already more or less controlled Nafta via SPP, it paid RWE 62.22 million Eur for its stake. This represents a price per share of about 12.44 Eur more than RWE paid over two years ago and about double the market price. One of the possible reasons why RWE decided to leave the company is, apart from uncertainty surrounding future participation in the company management, uncertainty regarding whether there is a profit to be made on future dividends. Another reason may be the joint operation of both rivals in a number of companies. And so the Nafta trade may be part of the establishment of areas of influence

    Full Text Available Agriculture has been one of the causes of deforestation, causing environmental impact and soil degeneration, which leads to lower income earned by farmers; hence the need to implement agroforestry systems .This research aims to describe fromthe initial growth of Eugenia stipitata, Inga edulis, and Inga spectabilis to 320 days after emergence. The study took place at the Amazon Research and Conservation Center of the Amazonas State University, during 2014 and 2015. The growth process was evaluated in regards to plant height, stem diameter, number of leaves, and branch length. Plant height and stem diameter were compared over time applying variance analysis. Precipitation was also compared to analyze whether its variations had a direct influence on plant growth. The linear and polynomial models fitted better for thespecies regarding plant height and sprout diameter. Predominance of green leaves compared to yellow and dry ones, as branch length showed significant differences over all the sampling periods. The two-way analysis of variance showed significant differences in the correlation between age and precipitation over plant height and stem diameter. The outcomes led to conclude that Eugenia stipitata had a lower growth than both Inga edulis and Inga spectabilis. Branch production and growth and the number of leaves were also important elements of the growth process.

    2002-01-01

    The reference Monte Carlo calculations of MARIA reactor core have been carried to evaluate accuracy of the calculations at each stage of its neutron-physics analysis using deterministic codes. The elementary cell has been calculated with two main goals; evaluation of effects of simplifications introduced in deterministic lattice spectrum calculations by the WIMS code and evaluation of library data in recently developed WIMS libraries. In particular the beryllium data of those libraries needed evaluation. The whole core calculations mainly the first MARIA critical experiment and the first critical core after the 8-year break in operation. Both cores contained only fresh fuel elements but only in the first critical core the beryllium blocks were not poisoned by Li-6 and He-3. Thus the MCNP k-eff results could be compared with the experiment. The MCNP calculations for the cores with beryllium poisoned suffered the deficiency of uncertainty in the poison concentration, but a comparison of power distribution shows that realistic poison levels have been carried out for the operating reactor MARIA configurations.

  12. Maria Montessori a different children glance

    Directory of Open Access Journals (Sweden)

    Vittoria Bosna

    2015-02-01

    Full Text Available Maria Montessori was  one of the most important female figures in the 20th-century Italian pedagogical overview. She deeply examined the child and his/her “absorbing” mind in a way that clarified the significant role played by the environment in cognitive and emotional education. Il metodo della pedagogia scientifica (1909 was her first study where she pointed out that science should analyse how the child’s personality develops in social interaction. Maria Montessori claimed children’s rights with respect to the adults’ world by underlining the traditional error -in psychological and educational terms-which used to compel the child to act not complying with his/her own nature. To this end, she organized the child’s educational context-that is the kindergarten- like an ideal place where the child could live his/her educational experiences by freely acting and by being appropriately stimulated. Montessori’s thought has led to fruitful implications related to such pedagogical topics as those currently tackled in contemporary pedagogy: i.e.: the relation between environment and education, the  organization of the teaching and  learning process, the use of procedures, methodologies and materials designed for a relevant pedagogical intervention.How to reference this articleBosna, V.

    Background: Eugenia pruniformis is an endemic species from Brazil. Eugenia genus has flavonoids as one of the remarkable chemical classes which are related to the improvement of the healing process. Aims: To evaluate of wound healing activity of E. pruniformis leaves and to identify and quantify its main flavonoids compounds. Materials And Methods: Wound excision model in rats was used to verify the hydroethanolic and ethyl acetate extracts potential. The animals were divided in four groups of six and the samples were evaluated until the 15° day of treatment. Hydroxyproline dosage and histological staining with hematoxilin-eosin and Sirius Red were used to observe the tissue organization and quantify the collagen deposition, respectively. Chemical compounds of the ethyl acetate extract were identified by chromatographic techniques and mass spectrometry analysis and total flavonoids content was determined by spectrophotometric method. The antioxidant activity was determined by oxygen radical absorbing capacity (ORAC) and 2,2-diphenyl-1-picrylhydrazylhydrate radical photometric (DPPH) assays. Results: The treated group with the ethyl acetate extract showed collagen deposition increase, higher levels of hidroxyproline, better tissue reorganization and complete remodeling of epidermis. Quercetin, kaempferol and hyperoside were identified as main compounds and flavonoids content value was 43% (w/w). The ORAC value of the ethyl acetate extract was 0.81± 0.05 mmol TE/g whereas the concentration to produce 50% reduction of the DPPH was 7.05± 0.09 μg/mL. Conclusion: The data indicate a wound healing and antioxidant activities of E. pruniformis. This study is the first report of flavonoids and wound healing activity of E. pruniformis. KEY MESSAGES Eugenia pruniformis extract accelerates wound healing in skin rat model, probably due to its involvement with the collagen deposition increase, higher levels of hidroxyproline, dermal remodelling and potent antioxidant activity

    Eugenia uniflora is widely used in Paraguayan folk medicine. A hydroalcoholic extract of the leaves showed some central nervous system activity in hippocratic screening when given intraperitoneally, but little to no acute or subacute toxicity in doses up to 4200 mg/kg orally in BALB c mice. The LD50 of the extract was 220 mg/kg i.p. in mice. A decoction or infusion of the leaves is recommended for treating gout by native herbalists. The known flavonoids quercitrin, quercetin, myricitrin and myricetin were found to be responsible for the xanthine oxidase inhibitory action of the plant extract.

    Online labor markets such as Amazon Mechanical Turk (MTurk) offer an unprecedented opportunity to run economic game experiments quickly and inexpensively. Using Mturk, we recruited 756 subjects and examined their behavior in four canonical economic games, with two payoff conditions each: a stakes condition, in which subjects' earnings were based on the outcome of the game (maximum earnings of $1); and a no-stakes condition, in which subjects' earnings are unaffected by the outcome of the game. Our results demonstrate that economic game experiments run on MTurk are comparable to those run in laboratory settings, even when using very low stakes.

  19. Multilevel stake holder consensus building in radioactive waste management

    2008-01-01

    Full text: The increased demand of our society to its quality of life, global security and environmental safety as well as to observing a basic ethical principle of equity have advanced our attitude towards the recent proposals to develop shared multinational projects in the use of nuclear energy technologies, in particular, to: a) Siting of shared deep repositories for high-level radioactive waste (RW) and spent nuclear fuel safe disposal. In turn, arrangement of multinational facilities requires to gain more complex consensus between all involved parties. Method: We propose an interdisciplinary synergetic approach to multilevel consensus building for siting and construction of shared multinational repositories for RW deep disposal, based on self-organization (SO) of various stake holders, chaos and fuzziness concepts as well as Ashby principle of requisite variety. In the siting of a multi-national repository there appears an essential novel component of stake holder consensus building, namely: to reach consent - political, social, economic, ecological - among international partners, in addition to solving the whole set of intra-national consensus building items. An entire partnering country is considered as a national stake holder, represented by the national government, being faced to simultaneous seeking an upward (international) and a downward (intra-national) consensus in a psychologically stressed environment, having possibly diverse political, economic and social interests. Main Results: Following inferences about building of multilevel consensus are developed: 1) The basis of synergetic approach to stake holder interaction - informational SO, by forming a knowledge-creating stake holder community via cooperation and competition among individuals, public bodies/groups, companies, institutions; 2) Building of international stake holder consensus could be promoted by activating and diversifying multilateral interactions between intra- and international stake

    This paper deals with the application of the RELAP5/MOD3 code to the transient analyses for MARIA research reactor. Poland's MARIA Research Reactor is water and beryllium moderated, water-cooled reactor of a pool type with pressurized fuel channels containing concentric multi-tube assemblies of highly enriched uranium clad in aluminium. The RELAP5/MOD3 input data model includes the whole primary cooling circuit of the MARIA reactor. The model was qualified against the reactor data at steady state conditions and additionally against the existing reliable experimental data for a transient initiated by the reactor scram. The RELAP transient simulation was performed for loss of forced flow accidents including two scenarios with protected and unprotected (no scram) reactor core. Calculations allow estimating time margin for reactor scram initiation and reactivity feedbacks contribution to the results. (author)

    1989-01-01

    Electric generating plant steam surface condensers have been prone to vibration induced tube failures. One common and effective method for stopping this vibration has been to insert stakes into the bundle to provide additional support. Stakes have been fabricated of a variety of rigid and semi-rigid materials of fixed dimensions. Installation difficulties and problems of incomplete tube support have been associated with this approach. New developments in the application of plastic technology has offered another approach. Stakes made of plastic tubes which are flattened, by evacuation, at the time of manufacture may now be easily inserted into the tube bundle. After insertion, the vacuum is released and the memory of the plastic causes the stakes to expand and assume their original form. The spring force of the plastic cradles the adjacent condenser tubes and stops the vibration. Developed for Electricite de France (EDF), the stakes are currently installed in 19 units of the French utility system, and two units in the United States

    Objective: To compare the antihyperlipidemic effects of Eugenia Jambolana fruit pulp with Punica Granatum fruit in diet induced hyperlipidaemic rats at the same dose level. Methods: An experimental randomized control study was conducted on seventy five male albino rats over a period of 14 weeks in University of Health Sciences Lahore. They were divided into five groups labelled A, B, C, D and E with fifteen rats in each group. Group A was kept as normal control, groups B, C, D and E were given hyperlipidaemic diet for six weeks. In group B no further intervention was done, group C and D were given ethanolic extract of Eugenia Jambolana and Punica Granatum respectively for eight weeks. Group E was given combination of both for same duration. Serum total cholesterol (TC), high density lipoprotein cholesterol (HDL-c), lowdensity lipoprotein cholesterol (LDL-c) and triglycerides (TG) were measured at zero, six and fourteen weeks. Results: At fourteenth week significant reductions in TC, LDL-c and TG and a rise in HDL-c was observed in interventional groups C, D and E as compared to experimental hyperlipidaemic control group B (p 0.57, p > 0.22, p > 0.56, p > 0.76, respectively. On sixth week, there was no significant difference between groups B, C, D and E (p > 0.05). However, 15 rats of group A had significant lower levels of cholesterol, high density lipoproteins, low density lipoproteins and triglycerides when compared to 60 rats of groups B, C, D and E (p<0.05). Conclusion: In male albino rats combination of ethanolic extracts of Eugenia Jambolana and Punica Granatum fruit pulps was most effective in lowering serum total cholesterol and triglycerides while decrease in low density lipoprotein cholesterol and rise in high density lipoprotein cholesterol was same as the extracts given alone.

    Full Text Available Over the last fifteen years, many states have implemented high-stakes tests as part of an effort to strengthen accountability for schools, teachers, and students. Predictably, there has been vigorous disagreement regarding the contributions of such policies to increasing test scores and, more importantly, to improving student learning. A recent study by Amrein and Berliner (2002a has received a great deal of media attention. Employing various databases covering the period 1990-2000, the authors conclude that there is no evidence that states that implemented high-stakes tests demonstrated improved student achievement on various external measures such as performance on the SAT, ACT, AP, or NAEP. In a subsequent study in which they conducted a more extensive analysis of state policies (Amrein & Berliner, 2002b, they reach a similar conclusion. However, both their methodology and their findings have been challenged by a number of authors. In this article, we undertake an extended reanalysis of one component of Amrein and Berliner (2002a. We focus on the performance of states, over the period 1992 to 2000, on the NAEP mathematics assessments for grades 4 and 8. In particular, we compare the performance of the high-stakes testing states, as designated by Amrein and Berliner, with the performance of the remaining states (conditioning, of course, on a state’s participation in the relevant NAEP assessments. For each grade, when we examine the relative gains of states over the period, we find that the comparisons strongly favor the high-stakes testing states. Moreover, the results cannot be accounted for by differences between the two groups of states with respect to changes in percent of students excluded from NAEP over the same period. On the other hand, when we follow a particular cohort (grade 4, 1992 to grade 8, 1996 or grade 4, 1996 to grade 8, 2000, we find the comparisons slightly favor the low-stakes testing states, although the discrepancy can

    Full Text Available High-stakes (dangerous, catastrophic risks take on a wider profile as progress unfolds. What are the impacts of technological and social change on the risk landscape? Due to the complexities and dynamics involved, we can only answer these questions approximately. By using the concept of fuzziness, we can formalize our imprecision about high-stakes risk, and therefore place their management on a stronger footing. We review here the impacts of fuzziness, i.e., knowledge imperfection, on high-stakes risk management, including its implementation via computationally intelligent decision aids.

    Candidiasis is the most frequent infection by opportunistic fungi such as Candida albicans, Candida tropicalis, and Candida krusei. Ethanol extract from Eugenia uniflora was assayed, for its antifungal activity, either alone or combined with four selected chemotherapeutic antimicrobial agents, including anphotericin B, mebendazole, nistatin, and metronidazole against these strains. The obtained results indicated that the association of the extract of E. uniflora to metronidazole showed a potential antifungal activity against C. tropicalis. However, no synergistic activity against the other strains was observed, as observed when the extract was associated with the other, not enhancing their antifungal activity.

    The rational basis for the use of Eugenia uniflora L. (Myrtaceae) as antihypertensive in Northeastern Argentina was assessed in normotensive rats. Intraperitoneal administration of the aqueous crude extract (ACE) decreased blood pressure (BP) of normotensive rats dose-dependently until 47.1 +/- 8.2% of control. The effective-dose 50 was 3.1 +/- 0.4 mg dried leaves/kg (d.l./kg) (yielding of ACE: 17% w/w). To determine the origin of hypotensive activity. Alpha-adrenergic antagonistic and vasorelaxant ACE activities were tested. The dose-response curve for phenylephrine on BP was inhibited non-competitively until 80% of its maximal effect (at 8 mg d.l. ACE/kg). Perfusion pressure (PP) of rat hindquarters (previously vasoconstricted by high-K+) was decreased by ACE in a concentration-dependent manner until -32.3 +/- 11.5% of tonic contraction at 1.2 g d.l. ACE/100 ml. In addition, A.C.E demonstrated diuretic activity at a dose (120 mg d.l./kg) higher than the hypotensive one. It was almost as potent as amiloride, but while amiloride induced loss of Na+ and saving of K+, ACE induced decrease in Na+ excretion. The results suggest that the empirical use of Eugenia uniflora L. (Myrtaceae) is mostly due to a hypotensive effect mediated by a direct vasodilating activity, and to a weak diuretic effect that could be related to an increase in renal blood flow.

    2015-12-01

    The role of politics has often been discussed in evaluation theory and practice. The political influence of the situation can have major effects on the evaluation design, approach and methods. Politics also has the potential to influence the decisions made from the evaluation findings. The current study focuses on the influence of the political context on stakeholder decision making. Utilizing a simulation scenario, this study compares stakeholder decision making in high and low stakes evaluation contexts. Findings suggest that high stakes political environments are more likely than low stakes environments to lead to reduced reliance on technically appropriate measures and increased dependence on measures better reflect the broader political environment.

    The Musa Granite and the Rio Maria Granodiorite are located at the eastern margin of the Amazonian craton, in the Rio Maria region, where a typical granite-greenstone terrain is characterized. Rb-Sr dating of six samples from different facies of Rio Maria Granodiorite furnished an age of 2564 ± 68 Ma with initial 87 Sr/ 86 Sr radio (IR) of 0.70288 ± 0.00092 (whole rock isochron; 1 ο error; MSWD = 2.26). Thirteen samples from the three facies of Musa Granite (monzogranites, syenogranites and intermediate to felsic hypabyssal rocks) gave Rb-Sr whole rock isochron with an age of 1692 ± 11 Ma and IR of 0.70777 ± 0.00023 (1 ο error, MSWD = 1.89). A preliminary attempt to individualize geochronologically the three facies was done resulting different ages and IRs. There is a coincidence between these ages and the emplacement sequence of these facies of the pluton. The actual meaning of the Rio Maria Granodiorite Rb-Sr age is still uncertain. It could be related to the end of the magmatic crystallization of the batholith as well as to the metamorphic-mylonitic event that affect it. Considering that the Jamon and Musa Granites are petrologically similar that they occur in the same area, it is interesting to note that latter is apparently a little older than the former. The IRs obtained for the two plutons are also not coincident. The isotopic Rb-Sr available data show that the exposed rocks of the Rio Maria Granodiorite have not been able to generate magmas with the compositions of the monzongranitic and the hypabyssal facies of the Musa pluton. On the other hand, rocks isotopically similar to the Rio Maria Granodiorite would theorically be able to generate the Jamon and a magma with the characteristics of the syenogranitic facies of the Musa pluton.

    Lupinus mariae-josephae is a recently discovered endemism that is only found in alkaline-limed soils, a unique habitat for lupines, from a small area in Valencia region (Spain). In these soils, L. mariae-josephae grows in just a few defined patches, and previous conservation efforts directed towards controlled plant reproduction have been unsuccessful. We have previously shown that L. mariae-josephae plants establish a specific root nodule symbiosis with bradyrhizobia present in those soils, and we reasoned that the paucity of these bacteria in soils might contribute to the lack of success in reproducing plants for conservation purposes. Greenhouse experiments using L. mariae-josephae trap-plants showed the absence or near absence of L. mariae-josephae-nodulating bacteria in “terra rossa” soils of Valencia outside of L. mariae-josephae plant patches, and in other “terra rossa” or alkaline red soils of the Iberian Peninsula and Balearic Islands outside of the Valencia L. mariae-josephae endemism region. Among the bradyrhizobia able to establish an efficient symbiosis with L. mariae-josephae plants, two strains, LmjC and LmjM3 were selected as inoculum for seed coating. Two planting experiments were carried out in consecutive years under natural conditions in areas with edapho-climatic characteristics identical to those sustaining natural L. mariae-josephae populations, and successful reproduction of the plant was achieved. Interestingly, the successful reproductive cycle was absolutely dependent on seedling inoculation with effective bradyrhizobia, and optimal performance was observed in plants inoculated with LmjC, a strain that had previously shown the most efficient behavior under controlled conditions. Our results define conditions for L. mariae-josephae conservation and for extension to alkaline-limed soil habitats, where no other known lupine can thrive. PMID:25019379

    The energy question today is worldwide and depends on major geopolitical stakes (demography, development, water, health, environment, research, risks). The energy must be universally produced and distributed together with minimizing pollutions, nuclear risks and CO 2 emissions. This new edition of 'the energy stakes' is fully updated and approaches some of the main questions that any responsible citizen should ask. It comprises 3 parts dealing with: a comprehensive review of the energy question in most of countries in the world, the constraints and challenges to take up to manage energy in an optimum way, and a prospective study about the control of energy consumption and about the existing technical solutions.

    The decision rules underpinning human cooperative behaviour are often investigated under laboratory conditions using monetary incentives. A major concern with this approach is that stake size may bias subjects' decisions. This concern is particularly acute in online studies, where stakes are often far lower than those used in laboratory or field settings. We address this concern by conducting a Dictator Game using Amazon Mechanical Turk. In this two-player game, one player (the dictator) determines the division of an endowment between himself and the other player. We recruited subjects from India and the USA to play an online Dictator Game. Dictators received endowments of $1, $5 or $10. We collected two batches of data over two consecutive years. We found that players from India were less generous when playing with a $10 stake. By contrast, the effect of stake size among players from the USA was very small. This study indicates that the effects of stake size on decision making in economic games may vary across populations.

  4. Correlates of cooperation in a one-shot high-stakes televised prisoners' dilemma.

    Maxwell N Burton-Chellew

    Full Text Available Explaining cooperation between non-relatives is a puzzle for both evolutionary biology and the social sciences. In humans, cooperation is often studied in a laboratory setting using economic games such as the prisoners' dilemma. However, such experiments are sometimes criticized for being played for low stakes and by misrepresentative student samples. Golden balls is a televised game show that uses the prisoners' dilemma, with a diverse range of participants, often playing for very large stakes. We use this non-experimental dataset to investigate the factors that influence cooperation when "playing" for considerably larger stakes than found in economic experiments. The game show has earlier stages that allow for an analysis of lying and voting decisions. We found that contestants were sensitive to the stakes involved, cooperating less when the stakes were larger in both absolute and relative terms. We also found that older contestants were more likely to cooperate, that liars received less cooperative behavior, but only if they told a certain type of lie, and that physical contact was associated with reduced cooperation, whereas laughter and promises were reliable signals or cues of cooperation, but were not necessarily detected.

    Chagas disease is caused by Trypanosoma cruzi, being considered a public health problem. An alternative to combat this pathogen is the use of natural products isolated from fruits such as Eugenia uniflora, a plant used by traditional communities as food and medicine due to its antimicrobial and biological activities. Ethanolic extract from E. uniflora was used to evaluate in vitro anti-epimastigote and cytotoxic activity. This is the first record of anti-Trypanosoma activity of E. uniflora, demonstrating that a concentration presenting 50% of activity (EC(50)) was 62.76 μg/mL. Minimum inhibitory concentration (MIC) was ≤ 1024 μg/mL. Our results indicate that E. uniflora could be a source of plant-derived natural products with anti-epimastigote activity with low toxicity.

    2010-01-01

    Major nutrient status of vermicompost of vegetable market waste (MW) and floral waste (FW) processed by three species of earthworms namely, Eudrilus eugeniae, Eisenia fetida, and Perionyx excavatus and its simple compost were assessed across different periods in relation to their respective initiative substrates. Their physical parameters temperature, moisture, ph, and electrical conductivity were also recorded. The nutrients nitrogen, phosphorus, potassium, calcium, and magnesium increased in the vermicompost and compost while the organic carbon, C/N and C/P ratios decreased as the composting process progressed from 0 to 15, 30, 45, and 60 days. The nutrient statuses of vermicomposts of all earthworm species produced from both the wastes were more than that of the compost and that of their respective substrates. Moreover, the vermicompost produced by E. eugeniae possessed higher nutrient contents than that of E. fetida, P. excavatus, and compost. The MW showed higher nutrient contents than the FW. Thus, vermicomposting is the paramount approach of nutrient recovery of urban green waste.

  11. Maria Carolina and Marie Antoinette: Sisters and Queens in the mirror of Jacobin Public Opinion

    Directory of Open Access Journals (Sweden)

    Cinzia Recca

    2014-09-01

    Full Text Available Marie Antoinette of Franceand Maria Carolina of Naples, both consorts, contributed to a flourishing of matronage, reproducing conceptions of royal femininity that embraced both the private and public roles they were expected to fulfil. However, while the political role of the first Queen has been largely reconsidered, her sister Maria Carolina has not yet been adjudicated impartially. This is somewhat curious, because Maria Carolina inherited from her sister the same disregard towards the Revolution and this, as perceived by the Jacobins, was duly proposed in their acrimonious criticism of her political role. This paper aims to focus on this criticism, analysing how the charges against Maria Carolina in the post-French revolutionary period, were a political duplication of the Jacobin attacks on Marie Antoinette from 1791 onwards. From this point of view, the paper will focus on the portrait of Maria Carolina in 1793 revolutionary Parisby Giuseppe Gorani, an Italian Jacobin noble. His Mémoires Secrets – where Maria Carolina was represented as a wicked woman in the same terms previously employed to denounce her sister Marie Antoinette by the French Republicans – was well known across Italy. This subject dominated the main pamphlets and brochures published in Naples in 1799, during the brief duration of the Neapolitan Republic, because it legitimised the rebellion against the monarchy. After the fall of the Neapolitan Republic, the political attacks on Maria Carolina continued likewise in France, where many Neapolitan patriots were obliged to flee. Analysing  Giuseppe Gorani’s Mémoires we gather that the portrait of Marie Antoinette’s sister was painted according to the main stereotypes of  French revolutionary political culture.

    Zinc (Zn) and chromium (Cr) act as essential nutrients; however, they can be toxic at higher concentrations. In this study, earthworm species Eudrilus eugeniae was studied for its sensitivity to sublethal doses of Cr (8 ppm) and Zn (350 ppm) in terms of alterations occurred in oxidative stress indices and reproductive parameters in the testis. A significant (p food intake was observed on 7, 14 and 21 days of Cr toxicity; while increased rate was evident upon 7 days of Zn exposure. Changes evident in the rate of cocoon production (-39.54 and +38.63 %), hatchability (-77.85 and +30.0 %) highlight higher toxic potential of Cr than Zn, respectively. Moderate to severe vacuolization in spermatic follicles and higher incidence of tailless (+52.6 % in Cr and 20.8 % in Zn), and head bent (+18.8 % in Cr and 0 % in Zn) sperms were evident in Cr(VI) exposed worms emphasizing the higher vulnerability of E. eugeniae to Cr toxicity. A significant (p implied from results that excessive free radical production and inadequate antioxidant defenses have lead to morphological alterations in sperms which sequentially reduced the reproductive rate.

We recruited subjects from India and the USA to play an online Dictator Game. Dictators received endowments of $1, $5 or $10. We collected two batches of data over two consecutive years. We found that players from India were less generous when playing with a $10 stake. By contrast, the effect of stake size among players from the USA was very small. This study indicates that the effects of stake size on decision making in economic games may vary across populations.

  16. Application of WIMSD-4 for ''MARIA'' reactor lattice calculations

    1993-12-01

    A general description of the WIMSD-4 lattice code is given with the emphasis on available geometrical models. The difficulties encountered while modelling reactor lattices with the tubular type fuel elements are explained. Then the analysis of code options allowing to overcome these difficulties is carried out. Eventually, recommendations of options and input parameters for calculations of MARIA reactor lattice with satisfactory accuracy are given. During the work a set of modifications had to be introduced leading to a new code version called WIMS-S. Another version, under the name WIMS-T has been developed to allow for burnup calculations of the MARIA reactor lattice with improved resonance approach. (author). 14 refs, 6 figs, 10 tabs

    Full Text Available This paper's main issue is linked to what can be foreseen as the increasing capability of medical genetics to modify the genetic composition of the human species through direct interventions in the human genome for medical and non-medical purposes, i.e., the 'risk' of a resurgence of eugenics. In current discussions on the topic (briefly presented in the first section, the 'phantom of eugenics' is raised several times, but there is a great deal of confusion on what counts as eugenics, partly because of broad conceptual disagreement over the notion itself. Furthermore, according to some scholars there is no hope of overcoming this unsatisfactory conceptual uncertainty. Partly challenging this opinion, the second and third sections of this paper attempt to identify some basic features which could be seen as intrinsically linked to the notion of eugenics, with the aim of reducing the range of conceptual disagreement as a preliminary step in bringing into focus what exactly is wrong with practicing eugenics. The subsequent sections deal with the substantive issue of whether or not to practice eugenics from the point of view of the interest of future generations in the human species' genetic composition. The main moral arguments for and against eugenics are examined from the point of view of our obligations towards future generations, and the conclusion is in favor of a cautious 'open-door' position.O ponto principal desse artigo está vinculado ao que pode ser antevisto como a crescente capacidade da genética médica de modificar a espécie humana por meio de intervenções diretas no genoma humano com propósitos médicos e não médicos, isto é, o risco do ressurgimento da eugenia. Nas atuais discussões sobre o tópico, o fantasma da eugenia é levantado diversas vezes, mas há grande confusão no que se refere ao que é considerado como eugenia, particularmente em razão da ampla discordância sobre a noção em si.

    Wood, A.

    1993-01-01

    Huntsman Chemical (Salt Lake City) has bought a 50% stake in Australian styrenics maker Chemplex (Melbourne) from Consolidated Press Holdings (Sydney). Huntsman stepped in after a previous acquisition plan by South Africa's Sentrachem (Johannesburg) broke down because of a failure to agree on price. Chemplex has two production locations near Melbourne: West Footscray, with capacity for 100,000 m.t./year of styrene, plus polystyrene, phenol, and acetone; and Dandenong, with production of acrylonitrile butadiene styrene and latex. The company was originally Monsanto Australia, before being acquired by Consolidated Press in 1988. The deal will give Huntsman its first major production position in the Asia/Pacific region, apart from a 50% stake in a 25,000-m.t./year polystyrene plant in Taiwan, with Grand Pacific Petrochemical (Taipei) as a partner. In 1991, Huntsman abandoned plans to invest in a 25,000-m.t./year polystyrene plant in Thailand with Mitsubishi Corp. and Toa (Bangkok). Huntsman Chemical has annual revenues of $1.3 billion

    1991-01-01

    The Rio Maria Region, southeastern part of the Amazonian craton (Brazil), displays a typical Archaean granite-greenstone association intruded by Proterozoic granites. The greenstone is crosscut by Archaean granitoids, such as the Rio Maria granodiorite. Clear field contacts between the Xingu gneisses and the granodiorite are lacking, making it difficult to determine the stratigraphic sequence. U-Pb data for zircons from the Xingu gneiss and the Rio Maria granodiorite provide upper intercept ages of 2971 +30/ -28 Ma and 2874 +9/ -10 Ma respectively on the Concordia diagram. 2.97 Ga is the most ancient age ever obtained on zircons from gneisses of the Amazonian craton. It provides an upper limit for the beginning of the continental crust formation in this part of the craton. (author)

    Neutron physics parameters of CERCA design fuel elements were calculated in the framework of the RERTR (Reduced Enrichment for Research and Test Reactors) program for Maria reactor. The analysis comprises burnup of experimental CERCA design fuel elements for 4 cycles in Maria Reactor To predict the behavior of the mixed core the differences between the CERCA fuel (485 g U-235 as U 3 Si 2 , 5 fuel tubes, low enrichment 19.75 % - LEU) and the presently used MR-6 fuel (430 g as UO 2 , 6 fuel tubes, high enrichment 36 % - HEU) had to be taken into account. The basic tool used in neutron-physics analysis of Maria reactor is program REBUS using in its dedicated libraries of effective microscopic cross sections. The cross sections were prepared using WIMS-ANL code, taking into account the actual structure, temperature and material composition of the fuel elements required preparation of new libraries.The problem is described in the first part of the present paper. In the second part the applicability of the new library is shown on the basis of the fuel core computational analysis. (author)

    Full Text Available Eugenia brasiliensis Lam. is a variable species concerning fruit colour, with three recognized varieties. However, the definition of varieties is not easy for Myrtaceae species and not widely accepted. Two fruit colour varieties (purple and yellow of E. brasiliensis had their essential oil composition analysed in order to give support to the existence of varieties for this species. Although, the major components in the leaf oil are the same monoterpenes for both varieties, alpha-pinene, beta-pinene and 1,8-cineol, the purple fruit variety accumulates more oxygenated sesquiterpenes (33.9% than the one with yellow fruits (3.8%. The major differences occurred in purple fruits that present as major components caryophyllene oxide (22.2% and alpha-cadinol (10.4%, not found in the leaf oil, and the yellow fruit oil presented a similar composition as observed for the leaves. These fruit colour varieties of E. brasilensis can be considered as two distinct chemotypes, since the sesquiterpene pathway is more operant in the purple variety than in the yellow one, in which monoterpenes are mainly accumulated.A espécie Eugenia brasiliensis Lam. apresenta a coloração dos frutos variável, sendo reconhecidas três variedades. Entretanto, a definição de variedades não é fácil para espécies de Myrtaceae e também não é amplamente aceita.

    microRNAs or miRNAs are small non-coding regulatory RNAs that play important functions in the regulation of gene expression at the post-transcriptional level by targeting mRNAs for degradation or inhibiting protein translation. Eugenia uniflora is a plant native to tropical America with pharmacological and ecological importance, and there have been no previous studies concerning its gene expression and regulation. To date, no miRNAs have been reported in Myrtaceae species. Small RNA and RNA-seq libraries were constructed to identify miRNAs and pre-miRNAs in Eugenia uniflora. Solexa technology was used to perform high throughput sequencing of the library, and the data obtained were analyzed using bioinformatics tools. From 14,489,131 small RNA clean reads, we obtained 1,852,722 mature miRNA sequences representing 45 conserved families that have been identified in other plant species. Further analysis using contigs assembled from RNA-seq allowed the prediction of secondary structures of 25 known and 17 novel pre-miRNAs. The expression of twenty-seven identified miRNAs was also validated using RT-PCR assays. Potential targets were predicted for the most abundant mature miRNAs in the identified pre-miRNAs based on sequence homology. This study is the first large scale identification of miRNAs and their potential targets from a species of the Myrtaceae family without genomic sequence resources. Our study provides more information about the evolutionary conservation of the regulatory network of miRNAs in plants and highlights species-specific miRNAs.

  11. Nutrient Status of Vermicompost of Urban Green Waste Processed by Three Earthworm Species—Eisenia fetida, Eudrilus eugeniae, and Perionyx excavatus

    Full Text Available Major nutrient status of vermicompost of vegetable market waste (MW and floral waste (FW processed by three species of earthworms namely, Eudrilus eugeniae, Eisenia fetida, and Perionyx excavatus and its simple compost were assessed across different periods in relation to their respective initiative substrates. Their physical parameters—temperature, moisture, pH, and electrical conductivity—were also recorded. The nutrients—nitrogen, phosphorus, potassium, calcium, and magnesium—increased in the vermicompost and compost while the organic carbon, C/N and C/P ratios decreased as the composting process progressed from 0 to 15, 30, 45, and 60 days. The nutrient statuses of vermicomposts of all earthworm species produced from both the wastes were more than that of the compost and that of their respective substrates. Moreover, the vermicompost produced by E. eugeniae possessed higher nutrient contents than that of E. fetida, P. excavatus, and compost. The MW showed higher nutrient contents than the FW. Thus, vermicomposting is the paramount approach of nutrient recovery of urban green waste.

    Full Text Available Hurricanes Irma and Maria struck Puerto Rico on the 6th and 20th of September 2017, respectively. These two powerful Cat 5 hurricanes severely defoliated forest canopy and deposited massive amounts of litterfall in the forests across the island. We established a 1-ha research plot in each of four forests (Guánica State Forest, Río Abajo State Forest, Guayama Research Area and Luquillo Experiment Forest before September 2016, and had collected one full year data of litterfall production prior to the arrival of Hurricanes Irma and Maria. Hurricane-induced litterfall was collected within one week after Hurricane Irma, and within two weeks after Hurricane Maria. Each litterfall sample was sorted into leaves, wood (branches and barks, reproductive organs (flowers, fruits and seeds and miscellaneous materials (mostly dead animal bodies or feces after oven-drying to constant weight. Annual litterfall production prior to the arrival of Hurricanes Irma and Maria varied from 4.68 to 25.41 Mg/ha/year among the four forests, and annual litterfall consisted of 50–81% leaffall, 16–44% woodfall and 3–6% fallen reproductive organs. Hurricane Irma severely defoliated the Luquillo Experimental Forest, but had little effect on the other three forests, whereas Hurricane Maria defoliated all four forests. Total hurricane-induced litterfall from Hurricanes Irma and Maria amounted to 95–171% of the annual litterfall production, with leaffall and woodfall from hurricanes amounting to 63–88% and 122–763% of their corresponding annual leaffall and woodfall, respectively. Hurricane-induced litterfall consisted of 30–45% leaves and 55–70% wood. Our data showed that Hurricanes Irma and Maria deposited a pulse of litter deposition equivalent to or more than the total annual litterfall input with at least a doubled fraction of woody materials. This pulse of hurricane-induced debris and elevated proportion of woody component may trigger changes in

    Full Text Available The physiological quality of seeds of native species is important to produce healthy saplings and therefore guarantee the success of programs to recover disturbed vegetation. This reinforces the necessity for investigating the physiological quality of those seeds. To evaluate the effects of different drying rates on the germination, moisture content and storability of Eugenia involucrata diaspores, mature fruits collected at Mogi Guaçu, SP, Brazil had their epi- and mesocarps removed by washing and were dried at 30, 40 or 50ºC until their water content was reduced from 57% (fresh diaspores to 13% (final drying, totaling six drying levels. In a second experiment, diaspores had their moisture content reduced from 57% to 49%, at 30ºC, totaling six drying levels (0h, 1h, 2h, 3h, 4h and 5h, and were kept for 180 days in plastic bags under cold storage. The drying rate had no effect on tolerance to desiccation by E. involucrata diaspores; water contents lower than 51% decreased both germinability and storability. Diaspores can be stored for up to 180 days as long as their water content is reduced to 53% and they are kept inside plastic bags under cold storage.O uso de sementes de espécies nativas de alta qualidade é fundamental nos programas de recomposição vegetal, o que fortalece a necessidade de se investigar o potencial fisiológico das mesmas.

    Full Text Available The objective of this work was to evaluate the performance of 'Rocha' and 'Santa Maria' pears at two planting densities. The experiment was carried out during the 2011/2012, 2012/2013, and 2013/2014 growing seasons, in one-year-old orchards (2011/2012 of 'Rocha' and 'Santa Maria' pears, trained in a central-leader system and planted in two densities (2,000 and 4,000 trees per hectare. The assessed parameters were: production per hectare, production per tree, yield efficiency, number of fruit per tree, average fruit weight, trunk diameter increment, fruit firmness, and soluble solid contents. The cumulative yield of 'Rocha' is greater at the higher planting density, whereas the yield efficiency of 'Santa Maria' increases at the lower planting density, as the trees get more mature. Trunk diameter of 'Rocha' also increases at the lower planting density. However, fruit quality parameters in both cultivars are little affected by planting density.

In her posthumous work Una donna libera Maria sums up her life from those years just to the time before her death: it is the autobiography of a self-taught woman that was, despite everything and everyone, a free woman slave to nothing – nor political ideas, nor a comfortable and bourgeois life – or anyone – family or love –, always coherent with her ideals and ready to fight for the fundamental human rights. Una donna libera tells us the story of a pilgrim in the world, a rebel, a rather difficult woman, uncomfortable for institutions and people, including intellectuals.

    Phytochemical investigation of Eugenia copacabanensis allowed for the isolation and identification of following compounds: β-sitosterol, β-sitosterol-glucoside, eight triterpenes, (mixture of α- and β-amyrins, ursolic acid, 30-hydroxy-ursolic acid, betulin, friedelin, friedelan-3,4-lactone, and taraxerol), a mixture of three sesquiterpenes, (clovandiol, globulol, and viridiflorol), three flavonoids (kaempferol-3-O-β-D-rhamnoside, quercetin-3-O-α-L-arabinoside, and quercetin), and a mixture of four coumaroyl esters (octacosanyl, heptacosanyl, hexacosanyl, and tetracosanyl coumarates). The structures of these compounds were assigned based on comparison with literature data and spectroscopic analysis, including analysis by two-dimensional NMR techniques. Total phenolic content and total flavonoids were evaluated. Antioxidant activities of methanol extracts and fractions were measured by the 1,2-diphenyl-2-picryl-hidrazyl free radical scavenging assay. (author)

  8. Re-analysis of NAEP Math and Reading Scores in States with and without High-stakes Tests: Response to Rosenshine

    2003-08-01

    Full Text Available Here we address the criticism of our NAEP analyses by Rosenshine (2003. On the basis of his thoughtful critique we redid some of the analyses on which he focused. Our findings contradict his. This is no fault of his, the reasons for which are explained in this paper. Our findings do support our position that high-stakes tests do not do much to improve academic achievement. The extent to which states with high-stakes tests outperform states without high-stakes tests is, at best, indeterminable. Using 1994-1998 NAEP reading and 1996-2000 NAEP math data and accounting for NAEP exemption rates for the same years, we found that states with high-stakes tests are not outperforming states without high-stakes tests in reading in the 4th grade or math in the 8th grade at a statistically significant level. States with high-stakes tests are, however, outperforming states without high-stakes tests in math in the 4th grade at a statistically significant level. Our findings also support our earlier stance that states with high-stakes tests are exempting more students from participating in the NAEP than are states without high-stakes tests. This is more prevalent the more recent the NAEP test administration. This is illustrated in the tables below.

    Full Text Available To support scientific visualization of multiple-mission data from Mars, the Virtual Astronaut (VA creates an interactive virtual 3D environment built on the Unity3D Game Engine. A prototype study was conducted based on orbital and Opportunity Rover data covering Santa Maria Crater in Meridiani Planum on Mars. The VA at Santa Maria provides dynamic visual representations of the imaging, compositional, and mineralogical information. The VA lets one navigate through the scene and provides geomorphic and geologic contexts for the rover operations. User interactions include in-situ observations visualization, feature measurement, and an animation control of rover drives. This paper covers our approach and implementation of the VA system. A brief summary of the prototype system functions and user feedback is also covered. Based on external review and comments by the science community, the prototype at Santa Maria has proven the VA to be an effective tool for virtual geovisual analysis.

    2004-01-01

    Maria Tranquillitatis and Fecunditatis have been mapped based on Clementine image mosaics and derived iron and titanium maps. Impact craters served as stratigraphic probes enabling better delineation of compositionally different basaltic units, determining the distribution of subsurface basalts, and providing estimates of total basalt thickness and the thickness of the surface units. Collected data indicate that volcanism in these maria started with the eruption of low-Ti basalts and evolved toward medium- and high-Ti basalts. Some of the high-Ti basalts in Mare Tranquillitatis began erupting early and were contemporaneous with the low- and medium-Ti basalts; these units form the oldest units exposed on the mare surface. Mare Tranquillitatis is mostly covered with high- Ti basalts. In Mare Fecunditatis, the volume of erupting basalts clearly decreased as the Ti content increased, and the high-Ti basalts occur as a few patches on the mare surface. The basalt in both maria is on the order of several hundred meters thick and locally may be as thick as 1600 m. The new basalt thickness estimates generally fall within the range set by earlier studies, although locally differ. The medium- to high-Ti basalts exposed at the surfaces of both maria are meters to tens of meters thick.

    Industrial technology already tested in Norway, North America and Algeria, the CO 2 capture and sequestration (CCS) consists in collecting carbon dioxide and to inject it into deep geological traps. This solution, which contributes to the fight against climatic change, arouses a growing up interest in France as a consequence of the Grenelle Environnement meetings. At a time when big research and demonstration programs are launched everywhere in Europe, this book proposes for the first time a status of the knowledge gathered so far by the specialists of the IPG (World Physics Institute), of the BRGM (Bureau of Geologic and Mining Researches), of the IFP (French Petroleum Institute), and of the CNRS (National Center of Scientific Research). It takes stock of the stakes of this new technology in France. Beyond the technical discussions between experts, the book deals with the external communication stakes and the open public debates. The point of views of the different intervening parties (research organizations, environmental non-governmental organizations, European lobby (Zero Emission Platform), citizens, journalists and companies are compared. A large part of the book aims at shading light on the social acceptability question of this technology. In addition to a synthesis of the available literature, it presents and analyses two participation instruments: a dialogue workshop and a geographical information web site. Content: 1 - scientific stakes of CO 2 geologic sequestration; 2 - technical stakes; 3 - economical stakes; 4 - risks and public opinion; 5 - social acceptability and territorial planning, the wind energy experience; 6 - the point of view of Action-Climat-France network (RAC-F); 7 - citizens' recommendations; 8 - the comeback of coal on the international energy scene; 9 - some consensus from a 'dialogue workshop': the social acceptability of CCS; 10 - bibliographic synthesis about the social acceptability of CCS; 11 - METSTOR, the interactive maping at

    2007-01-01

    AREVA announced the acquisition of a 51% stake in Multibrid, a designer and manufacturer of multi-megawatt off-shore wind turbines based in Germany. With this acquisition, AREVA has entered into a joint venture with Prokon Nord, a German off-shore wind turbine and biomass plant developer and current owner of Multibrid. This transaction values Multibrid at euro 150 million. AREVA plans to rapidly further develop Multibrid's activities by giving the company access to its industrial resources, financial base and international commercial network. In return, Multibrid will provide AREVA with its leading-edge technology which, developed for 5 MW turbines, can achieve a very high output while reducing operating costs thanks to a simplified maintenance system. With this stake in Multibrid, AREVA aims to increase its presence on the offshore wind market that meets land settlement requirements and that should grow significantly in the years to come (from 300 MW in Europe today to an expected 1400 MW by 2011). As an exclusive supplier of Prokon Nord, Multibrid will participate in projects such as Borkum West (30 MW), the first offshore project in Germany, Borkum West 2 (400 MW), and Cote d'Albatre (105 MW), the first offshore wind farm project in France. The stake in Multibrid strengthens AREVA's strategic positioning on the CO 2 -free energy market, thanks to complementary solutions ranging from nuclear technologies to renewables. A number of recent achievements illustrate this strategy: - bio-energy (crucial energy supply in numerous rural areas): delivery of turnkey biomass power plants; ongoing construction of 10 plants in India, Thailand and Brazil; future development plans in fast-growing regions, such as Latin America; - wind power: Multibrid adds to the Group's stake in REpower and to its partnership with Suzlon for which AREVA is the number one supplier of transmission and distribution solutions for wind power; - hydrogen and fuel cells: design and manufacture of

    Nasopharyngeal carcinoma (NPC) is one of the high population malignant tumors among Chinese in southern China and southeast Asia. Epstein-Barr virus (EBV) is a human B lymphotropic herpes virus which is known to be closely associated with NPC. EBV DNA polymerase is a key enzyme during EBV replication and is measured by its radioactivity. The addition of phorbol 12-myristate 13-acetate to Raji cell cultures led to a large increase in EBV DNA polymerase, which was purified by sequential DEAE-cellulose, phosphocellulose and DNA-cellulose column chromatography. Four tannins were isolated from the active fractions of Eugenia uniflora L., which were tested for the inhibition of EBV DNA polymerase. The results showed the 50% inhibitory concentration (IC(50)) values of gallocatechin, oenothein B, eugeniflorins D(1) and D(2) were 26.5 62.3, 3.0 and 3.5 microM, respectively. Furthermore, when compared with the positive control (phosphonoacetic acid), an inhibitor of EBV replication, the IC(50) value was 16.4 microM. In view of the results, eugeniflorins D(1) and D(2) are the potency principles in the inhibition of EBV DNA polymerase from E. uniflora.

    Mindfulness enhances emotion regulation and cognitive performance. A mindful approach may be especially beneficial in high-stakes academic testing environments, in which anxious thoughts disrupt cognitive control. The current studies examined whether mindfulness improves the emotional response to anxiety-producing testing situations, freeing working memory resources, and improving performance. In Study 1, we examined performance in a high-pressure laboratory setting. Mindfulness indirectly benefited math performance by reducing the experience of state anxiety. This benefit occurred selectively for problems that required greater working memory resources. Study 2 extended these findings to a calculus course taken by undergraduate engineering majors. Mindfulness indirectly benefited students' performance on high-stakes quizzes and exams by reducing their cognitive test anxiety. Mindfulness did not impact performance on lower-stakes homework assignments. These findings reveal an important mechanism by which mindfulness benefits academic performance, and suggest that mindfulness may help attenuate the negative effects of test anxiety.

    2008-06-01

    The Drug Control Authority (DCA) of Malaysia implemented the phase three registration of traditional medicines on 1 January, 1992. A total of 100 products in various pharmaceutical dosage forms of a herbal preparation, containing Eugenia dyeriana, either single or combined preparations (more than one medicinal plant), were analyzed for the presence of lead contamination, using atomic absorption spectrophotometry. These samples were bought from different commercial sources in the Malaysian market, after performing a simple random sampling. Results showed that 22% of the above products failed to comply with the quality requirement for traditional medicines in Malaysia. Although this study showed that 78% of the products fully complied with the quality requirement for traditional medicines in Malaysia pertaining to lead, however, they cannot be assumed safe from lead contamination because of batch-to-batch inconsistency.

    Essential oil (EO) of the leaves of Eugenia uniflora L. (Brazilian cherry tree) was evaluated for its antioxidant, antibacterial and antifungal properties. The acute toxicity of the EO administered by oral route was also evaluated in mice. The EO exhibited antioxidant activity in the DPPH, ABTS and FRAP assays and reduced lipid peroxidation in the kidney of mice. The EO also showed antimicrobial activity against two important pathogenic bacteria, Staphylococcus aureus and Listeria monocytogenes, and against two fungi of the Candida species, C. lipolytica and C. guilliermondii. Acute administration of the EO by the oral route did not cause lethality or toxicological effects in mice. These findings suggest that the EO of the leaves of E. uniflora may have the potential for use in the pharmaceutical industry. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Fast retrieval of digital content has become mandatory for library and archive information systems. Many software applications have emerged to handle the indexing of digital content, from low-level ones such Apache Lucene, to more RESTful and web-services-ready ones such Apache Solr and ElasticSearch. Solr’s popularity among library software developers makes it the “de-facto” standard software for indexing digital content. For content (full-text content or bibliographic description already stored inside a relational DBMS such as MariaDB (a fork of MySQL or PostgreSQL, Sphinx Search Server (Sphinx is a suitable alternative. This article will cover an introduction on how to use Sphinx with MariaDB databases to index database content as well as some examples of Sphinx API usage.

    Comparative toxicity of two chemical pesticides (temephos and monocrotophos) versus a plant-derived betel leaf oil Piper betle (L.) to earthworm Eudrilus eugeniae (Kinberg) and redworm Eisenia fetida Savigny, historically: Eisenia foetida (Savigny 1826), was evaluated. Mortality rate was more prominent in temephos at 100 μg concentration to both the earthworms in filter paper test (FPT) as well as 10 mg concentration in artificial soil test (AST). In contrast, P. betle does not display much mortality rate to both the earthworms even at 1000 mg of treatment concentrations. The lethal concentration (LC 50 ) value was observed at 3.89 and 5.26 mg/kg for temephos and monocrotophos against E. eugeniae and 3.81 and 5.25 mg/kg to E. fetida, respectively. Whereas, LC 50 value of betel leaf oil was only observed at 3149 and 4081 mg/kg to E. eugeniae and E. fetida, respectively. Correspondingly, the avoidance or attraction assay also displayed that earthworms were more sensitive to the soil containing chemical pesticides. Whereas, the avoidance percentage was decreased in the P. betle oil. Similarly, sublethal concentration of chemical pesticides (5 and 6.5 mg) significantly reduced the earthworm weight and growth rate. However, P. betle oil did not change the developmental rate in the duration of the assay (2, 7 and 14 days) even at 4000 mg treatment concentration. The enzyme ratio of CAT and SOD was also affected significantly after exposure to the chemical pesticides (6.5 mg/kg). Hence, our study implied the risk assessment associated with the chemical pesticides and also recommends plant-derived harmless P. betle oil against beneficial species as an alternative pest control agent.

    2008-03-01

    Full Text Available This article draws on research from Texas and Chicago to examine whether high-stakes testing enables low-income and racial minority students to acquire cultural capital. While students' performance on state or district tests rose after the implementation of high-stakes testing and accountability policies in Texas and Chicago in the 1990s, several studies indicate that these policies seemed to have had deleterious effects on curriculum, instruction, the percentage of students excluded from the tests, and student dropout rates. As a result, the policies seemed to have had mixed effects on students' opportunities to acquire embodied and institutionalized cultural capital. These findings are consistent with the work of Shepard (2000, Darling-Hammond (2004a, and others who have written of the likely negative repercussions of high-stakes testing and accountability policies.

    Phytochemical investigation of Eugenia copacabanensis allowed for the isolation and identification of following compounds: β-sitosterol, β-sitosterol-glucoside, eight triterpenes, (mixture of α- and β-amyrins, ursolic acid, 30-hydroxy-ursolic acid, betulin, friedelin, friedelan-3,4-lactone, and taraxerol), a mixture of three sesquiterpenes, (clovandiol, globulol, and viridiflorol), three flavonoids (kaempferol-3-O-β-D-rhamnoside, quercetin-3-O-α-L-arabinoside, and quercetin), and a mixture of four coumaroyl esters (octacosanyl, heptacosanyl, hexacosanyl, and tetracosanyl coumarates). The structures of these compounds were assigned based on comparison with literature data and spectroscopic analysis, including analysis by two-dimensional NMR techniques. Total phenolic content and total flavonoids were evaluated. Antioxidant activities of methanol extracts and fractions were measured by the 1,2-diphenyl-2-picryl-hidrazyl free radical scavenging assay. (author)

    Eugenia dysenterica DC. (Myrtaceae) is a perennial tree producing edible fruits and ornamental flowers of potential value widely distributed in Brazilian "Cerrados" (savannas), but available genetic resources and potential for future breeding programs must be evaluated. Here we evaluated the reproductive system and pollen-mediated gene flow in one generation of Eugenia dysenterica germplasm collection of Agronomy School, Federal University of Goiás (in Goiânia city, Central Brazil). We collected leaves from all adults from the germplasm collection (682 plants) and seeds (542) from 23 mother-trees. Genotypes were obtained for seven microsatellite loci. Genetic diversity was high and did not significantly differ between adults (H e = 0.777) and progeny arrays (H e = 0.617). Our results showed that E. dysenterica has an allogamous mating system in the germplasm collection (t m = 0.957), but with high and significant biparental inbreeding (t m - t s = 0.109). Because sibs are very close to each other, mating between closely related individuals is likely. Paternity correlation was also relatively high, indicating a 11.9 % probability that a randomly chosen pair of outcrossed progeny from the same array are full sibs. The maximum pollen dispersal distance (224 m), estimated using assignment test, corresponded to the boundaries of the orchard. We were able to assign the paternity to only 64 % of the 349 seeds analyzed, indicating potential pollen immigration to the germplasm collection. The variance effective population size estimated for one maternal family in the germplasm collection (N ev = 3.42) is very close to the theoretical maximum value for half-sibs (Nev = 4.0). Because E. dysenterica has a long life cycle and generation time, the maintenance of an effective population size of at least 100 in the germplasm collection is suggested, which can be achieved by maintaining a seed-trees number around 30 individuals.

    2000 words Recovery efforts from natural disasters can be more efficient with data-driven information on current needs and future risks. We aim to advance open-source software infrastructure to support scientific investigation and data-driven decision making with a prototype system using a water quality assessment developed to investigate post-Hurricane Maria drinking water contamination in Puerto Rico. The widespread disruption of water treatment processes and uncertain drinking water quality within distribution systems in Puerto Rico poses risk to human health. However, there is no existing digital infrastructure to scientifically determine the impacts of the hurricane. After every natural disaster, it is difficult to answer elementary questions on how to provide high quality water supplies and health services. This project will archive and make accessible data on environmental variables unique to Puerto Rico, damage caused by Hurricane Maria, and will begin to address time sensitive needs of citizens. The initial focus is to work directly with public utilities to collect and archive samples of biological and inorganic drinking water quality. Our goal is to advance understanding of how the severity of a hazard to human health (e.g., no access to safe culinary water) is related to the sophistication, connectivity, and operations of the physical and related digital infrastructure systems. By rapidly collecting data in the early stages of recovery, we will test the design of an integrated cyberinfrastructure system to for usability of environmental and health data to understand the impacts from natural disasters. We will test and stress the CUAHSI HydroShare data publication mechanisms and capabilities to (1) assess the spatial and temporal presence of waterborne pathogens in public water systems impacted by a natural disaster, (2) demonstrate usability of HydroShare as a clearinghouse to centralize selected datasets related to Hurricane Maria, and (3) develop a

  2. Negotiating the terrain of high-stakes accountability in science teaching

    Science.gov (United States)

    Aronson, Isaak

    Teachers interact with their students on behalf of the entire educational system. The aim of this study is to explore how biology teachers understand and construct their practice in a high-stakes accountability environment that is likely to be riddled with tensions. By critically questioning the technical paradigms of accountability this study challenges the fundamental assumptions of accountability. Such a critical approach may help teachers develop empowerment strategies that can free them from the de-skilling effects of the educational accountability system. This interpretive case study of a high-school in Maryland is grounded in three streams of research literature: quality science instruction based on scientific inquiry, the effects of educational accountability on the curriculum, and the influence of policy on classroom practice with a specific focus on how teachers balance competing tensions. This study theoretically occurs at the intersection of educational accountability and pedagogy. In terms of data collection, I conduct two interviews with all six biology teachers in the school. I observe each teacher for at least fifteen class periods. I review high-stakes accountability policy documents from the federal, state, and district levels of the education system. Three themes emerge from the research. The first theme, "re-defining science teaching," captures how deeply accountability structures have penetrated the science curriculum. The second theme, "the pressure mounts," explores how high-stakes accountability in science has increased the stress placed on teachers. The third theme, "teaching-in-between," explores how teachers compromise between accountability mandates and their own understandings of quality teaching. Together, the three themes shed light on the current high-stakes climate in which teachers currently work. This study's findings inform the myriad paradoxes at all levels of the educational system.

    Most look into the benefits of the nanoparticles, but keeping aside the benefits; this study focuses on the impacts of nanoparticles on living systems. Improper disposal of nanoparticles into the environment is a subject of pollution or nano-pollution which in turn affects the flora and fauna in the ecosystem, particularly soil ecosystem. Thus, this study was done to understand the impacts of chemically synthesized magnetite nanoparticles on earthworm— Eudrilus eugeniae, a soil-dependent organism which acquires food and nutrition from decaying matters. The chemically synthesized magnetite nanoparticles were characterized by UV-visible spectrophotometry, Fourier transform infrared spectroscopy and field emission scanning electron microscopy. Earthworms were allowed to interact with different concentrations of synthesized nanoparticles and the effect of the nanoparticles was analysed by studying the phenotypic changes followed by histology and inductively coupled plasma optical emission spectrometry analyses.

    As energy transition implies important societal transformations, the authors developed an analysis framework about the main questions raised by local governance: role of the different levels of local communities in the definition and implementation of strategies, key stakes of the sharing of skills between the State and communities, and stakes regarding spatial planning in this context. The authors first address the issue of relevance of the different territorial scales in a context of evolution of energy policies. They propose an overview of this issue with reference to the debate on local governance of transition. They discuss the return on experience of decentralisation in other fields of action of local policies, notably urban planning and spatial planning

O objetivo do estudo foi investigar quantitativamente e qualitativamente os atos violentos contra as mulheres na cidade de Montes Claros, Minas Gerais. A vertente qualitativa pretendia conhecer o sentido da violência para as mulheres envolvidas e seus reflexos na família, através de entrevistas semiestruturadas que não se efetivaram. A partir da Análise Institucional de René Lourau analisamos essa inviabilidade como dado qualitativo, examinando o cotidiano da delegacia após a lei Maria da Penha. Concluímos que a intervenção judicial não é suficiente para a inibição da violência contra a mulher, pois em certos casos afasta da delegacia mulheres com outras demandas acerca da violência, que sofrem e que não podem contar com a ajuda policial para a resolução dos seus conflitos.

    The high flux Maria research reactor is operated by the National Centre for Nuclear Research in Świerk. It is a pool type reactor with pressurized fuel channels located in the beryllium matrix. According to the Global Threat Reduction Initiative programme our goal is to convert the Maria reactor from HEU to LEU fuel. Hydraulic losses in the new LEU fuel produced by CERCA are about 30% higher than the existing HEU fuel of type MR-6. For the MR-6 fuel were installed four two speed pumps. These pumps performed the function of the main circulations pumps during reactor operation with residual pumping power provided by emergency pumps. In the new system four main pumps will be used for circulating coolant while the reactor is operation with three auxiliary pumps for decay heat removal after reactor shutdown, meaning that the conversion of Maria research reactor will be possible after increasing flow in the primary cooling circuit of the fuel channels. The technical design of replacement of the pumps in the primary fuel channel cooling circuit was finished in April 2011 and accepted by the Safety Committee. After delivery of the new pumps we are planning to upgrade the primary fuel channel cooling circuit during October–November 2012. (author)

    The MARIA reactor is a high-flux multipurpose research reactor which is water-cooled and moderated with both beryllium and water. Standard HEU (80% 235 U)fuel assemblies consist of six concentric fuel tubes of a U-Al alloy clad in aluminum. Although the inventory of HEU (80%) fuel is nearly exhausted, a supply of highly-loaded 36%-enriched fuel assemblies is available at the reactor site. Neutronic equilibrium studies have been made to determine the relative performance of fuels with enrichments of 80%, 36% and 19.7%. These studies indicate that LEU (19.7%) densities of about 2.5 gU/cm 3 and 3.8 gU/cm 3 are required to match the performance of the MARIA reactor with 80%-enriched and with 36%-enriched fuels, respectively

    Precise computational determination of nuclear heating which consists predominantly of gamma heating (more than 80 %) is one of the challenges in material testing reactor exploitation. Due to sophisticated construction and conditions of experimental programs planned in JHR it became essential to use most accurate and precise gamma heating model. Before the JHR starts to operate, gamma heating evaluation methods need to be developed and qualified in other experimental reactor facilities. This is done inter alia using OSIRIS, MINERVE or EOLE research reactors in France. Furthermore, MARIA - Polish material testing reactor - has been chosen to contribute to the qualification of gamma heating calculation schemes/tools. This reactor has some characteristics close to those of JHR (beryllium usage, fuel element geometry). To evaluate gamma heating in JHR and MARIA reactors, both simulation tools and experimental program have been developed and performed. For gamma heating simulation, new calculation scheme and gamma heating model of MARIA have been carried out using TRIPOLI4 and APOLLO2 codes. Calculation outcome has been verified by comparison to experimental measurements in MARIA reactor. To have more precise calculation results, model of MARIA in TRIPOLI4 has been made using the whole geometry of the core. This has been done for the first time in the history of MARIA reactor and was complex due to cut cone shape of all its elements. Material composition of burnt fuel elements has been implemented from APOLLO2 calculations. An experiment for nuclear heating measurements and calculation verification has been done in September 2014. This involved neutron, photon and nuclear heating measurements at selected locations in MARIA reactor using in particular Rh SPND, Ag SPND, Ionization Chamber (all three from CEA), KAROLINA calorimeter (NCBJ) and Gamma Thermometer (CEA/SCK CEN). Measurements were done in forty points using four channels. Maximal nuclear heating evaluated from

    Full Text Available Abstract Microorganisms are the primary responsible for food poisoning and food spoilage. The purpose of this study was to evaluate different fruit washing methods with tap water, electrolyzed water and rhamnolipids solution produced by Pseudomonas aeruginosa LBI, in order to inhibit microbial growth. The tested organism was Eugenia uniflora. The fruits were washed and periodically inoculated into culture media to evaluate and count the colonies on the fruit surface. It was also observed the deterioration level of the fruits after each treatment. The results showed that treatment with rhamnolipids were the most efficient, inhibiting the growth of fungi and bacteria. The electrolyzed water proved to be very efficient in bacterial inhibition at the initial time, but in the final time it did not present any inhibitory effect. The electrolyzed water was also not effective in eliminating fungus. Washing with tap water was the less efficient treatment of all. The only treatment that showed an increased durability has been with rhamnolipids, increasing shelf life by up to two days. Thus rhamnolipids are the most recommended method for fruits sanitation.

    Eugenia uniflora, used ethnomedically in some tropical countries as an anti-infective, has shown anti-malarial and anti-trypanocidal activities. Therefore using bioactivity guided fractionation, anti-trichomonal activity of E. uniflora leaf was investigated. Anti-trichomonal activities of leaf methanol extract and its fractions against Trichomonas gallinae as well as their cytotoxicities using an in vitro haemaglutination assay were determined. Anti-trichomonacidal activities of the extract improved on purification up to a stage. Subfractions E(2-5) had LC(50) and LC(90) values of 4.77 - 5.28, 18.49 - 25.00 and 4.53 - 5.18, 18.32 - 19.07 µg/ml at 24 and 48 hrs, respectively that were better than those of metronidazole. Further purification of E(2-5) led to loss of activity suggesting that the active components were probably working synergistically and additively. Demonstration of low haemaglutination titre values of 0.00 - 5.33 by methanolic extract and its partition fractions suggested their low toxicity profile. The established safety of the leaf indicated that its anti-trichomonal activity was not due to non-specific cytotoxicity, hence could be used in ethnomedicine as an anti-trichomonal agent.

Pitanga with different flesh colors (purple, red, and orange from tree selections cultivated at Embrapa Clima Temperado (RS-Brazil were analyzed. Only slight differences were observed in the quality parameters and in the proximate and fatty acid compositions among the fruits studied. The extracts from purple-fleshed pitanga had the highest total phenolic and anthocyanin contents along with the highest antioxidant capacity. The antioxidant capacity (DPPH and FRAP assays of methanolic pitanga extracts was highly correlated with the total phenolic content, but in ethanolic extracts, the anthocyanin content was correlated only with the FRAP antioxidant capacity. Orange fleshed pitanga had higher β-cryptoxanthin and β-carotene levels than those of the red fruit, which had higher lycopene content. The results indicate that the purple-fleshed pitanga, cultivated in Rio Grande do Sul, is a rich source of phenolic compounds and has high antioxidant capacity. The red and orange-fleshed pitanga, on the other hand, are rich sources of carotenoids.

    In order to alleviate the distrust surrounding the use of nuclear energy and operation of nuclear facilities, as well as to foster trust and find better ways to live in harmony with society, it is essential for the state and electric power utilities not to provide one-sided information, but to formulate adequate bilateral communication and dialogue with stake holders. In this study, we conducted a case study focused on four stake holder meetings with a view to ensuring safety in the use of nuclear energy and operation of nuclear facilities in Japan; the 'Community Meeting for Securing the Transparency of Kashiwazaki-Kariwa Nuclear Power Station (Chiiki-no-kai)'; the 'Monitoring and Evaluation Conference on Environmental Radiation', established by communities where nuclear facilities are installed; the 'Round-Table Conference on Nuclear Power Policy' and the 'Conference for Public Participation and Decision Making for Nuclear Energy Policy' organized by Japan Atomic Energy Commission. As a consequence, it has been observed that in each case varying opinions were summarized through stake holder meetings, but the fact that no system exists to reflect these opinions in design of the nuclear energy policy has emerged as a controversial point. This study suggests future efforts in regard to the requirements in Japan for stake holder meetings that are necessary for fostering trust and mutual understanding among stake holders including the state and local government, electric power utilities and local residents.

    A 600 kW test loop facility for investigatin.o safety problems is realized on MARIA reactor in Poland together with USSR organizations. Safety reports have been developed in two steps at the designstage. The 1st report being essentially a preliminary safety analysis was developed within the scope of the feasibility study. At the engineering design stage the preliminary test loop facility safety report had been prepared considering measures excluding the possibility of the MARIA reactor damage. The test loop facility safety report is fulfilled for normal, transient and emergency operation regimes. Separate safety basing for each group of experiments will be prepared. The report presents the test loop facility safety criteria coordinated by the nuclear safety comission. They contains the preliminary reports on the test loop facility safety. At the final stage of construction and at thecommitioning stage the start-up safety report will be developed which after required correction and adding up the putting into operation data will turn into operation safety report [ru

    Eugenia uniflora L. is a member of the Myrtaceae family and is commonly known as Brazilian cherry tree. In this study, we evaluated the chemical composition of Eugenia uniflora L. essential oil (EuEO) by using gas chromatography-mass spectrometry (GC-MS) and assessed its anti-Leishmania activity. We also explored the potential mechanisms of action and cytotoxicity of EuEO. Thirty-two compounds were identified, which constituted 92.65% of the total oil composition. The most abundant components were sesquiterpenes (91.92%), with curzerene (47.3%), γ-elemene (14.25%), and trans-β-elemenone (10.4%) being the major constituents. The bioactivity shown by EuEO against promastigotes (IC50, 3.04 μg·mL−1) and amastigotes (IC50, 1.92 μg·mL−1) suggested significant anti-Leishmania activity. In the cytotoxicity determination, EuEO was 20 times more toxic to amastigotes than to macrophages. Hemolytic activity was 63.22% at the highest concentration tested (400 μg·mL−1); however, there appeared to be no toxicity at 50 μg·mL−1. While the data show that EuEO activity is not mediated by nitric oxide production, they do suggest that macrophage activation may be involved in EuEO anti-Leishmania activity, as evidenced by increases in both the phagocytic capacity and the lysosomal activity. More studies are needed to determine in vivo activity as well as additional mechanisms of the anti-Leishmania activity. PMID:23533469

    2011-11-01

    Full Text Available The essay presents a comparison between the thought of Ellen Key and that of Maria Montessori. Changes that involved the role of women, caught in its interdependence with the development of new educational practices, were the center of the theoretical contribution of Ellen Key. Maria Montessori believed that only women work outside the home would guarantee the economic independence necessary to form a union on sentiment rather than on utilitarian calculations and therefore she did not seem to share the concerns of the Key on an increasingly massive female entry into the world of work. The paper offers an updated reflection on the work of two scholars of education.

    Due to the lack of studies about neurocysticercosis in the South of Brazil, an investigation was conducted to determine the percentage of suspected cases of neurocysticercosis in computed tomography diagnoses in Santa Maria, RS, from January 1997 to December 1998. Of 6300 computed tomographies (CT) of the skull performed at the private Hospital de Caridade Astrogildo de Azevedo, 80, i.e., 1.27% were suspected of neurocysticercosis. Fifty were women (62.5%) and 30 were men (37.5%). The most frequent radiological manifestation indicating neurocysticercosis was the presence of calcifications (isolated or associated), with a 95% rate (76 cases), while the presence of hypodense lesions reached a 5% rate (4 cases). After routine analysis, each CT was evaluated again and the suspected cases were confirmed. The percentage of suspected cases of neurocysticercosis detected by CT in the present study carried out in Santa Maria was considered low (1.27%). This can be explained by the fact that tomography is not accessible to the economically underprivileged population of Santa Maria. We hope that the present study can alert the population and the professionals to the fact that neurocysticercosis is a more frequent disease than indicated by the few diagnoses made.

    Eugenia uniflora, referred to as Pitanga cherry shrub, is largely distributed in tropical and subtropical America. This plant is cultivated in many countries and it is suitable for the production of juice, frozen pulp, and tea. Besides, it can be used as treatment for inflammatory diseases. We reported that a flavonoid-rich fraction (HE-Bu) obtained from leaves decreased the lethality induced by cecal ligation and puncture (CLP), a clinically relevant model of sepsis. The oral administration of HE-Bu reduced the late mortality rate by 30%, prevented neutrophil accumulation in lungs, decreased TNF-α and IL-1β serum levels, and markedly decreased iNOS and COX-2 protein expression by ileum cells. Chemical investigation showed myricetin and quercetin rhamnosides as the major components of this fraction. The results showed that HE-Bu protected mice from sepsis and indicated that this edible plant produces compounds that could be considered as potential adjuvants for sepsis treatment.

    2012-09-01

    The current paper sought to analyze the repercussions of Maria da Penha Law on addressing the issue of domestic violence against women in the city of Porto Alegre based on the view of professionals who constitute the care network for those women. Seven professionals, who work with the care for women who are victims of violence, were interviewed. Data suggests that the law has promoted changes in the field of violence prevention, assistance to women and punishment for the perpetrators, and it also increased the attention given to this phenomenon and enhanced female empowerment. It is concluded that the strengthening of the measures recommended by Maria da Penha Law still depends on investments in professional qualification, articulated actions between the places which provide assistance and the growing use of primary care services in order to improve the health of women and families exposed to violence.

  8. Curricular constraints, high-stakes testing and the reality of reform in high school science classrooms

    Coble, Jennifer

    Through a series of open-ended interviews, this study investigated the beliefs of six third year high school science teachers about how they implement science education reform ideals in their practice and the contextual challenges they face as they attempt to implement reform. The teachers argue that the lack of connection between their curricula and students' lives serves as a significant obstacle to them utilizing more inquiry-based and student-centered strategies. In their science classes that are not subject to a high stakes exam, the teachers shared instances where they engage students in inquiry by refraining the focus of their curricula away from the decontextualized factual information and onto how the information relates to human experience. In their science classes subject to a high stakes test, however, the teachers confessed to feeling no choice but to utilize more teacher-centered strategies focused on information transmission. This study provides an in depth analysis of how the presence of high stakes tests discourages teachers from utilizing reform based teaching strategies within high school science classrooms.

    Full Text Available Plant extracts of Eugenia punicifolia (Kunth DC., Myrtaceae, are used in Amazon region of Brazil to treat diarrhea and stomach disturbances, and as hypoglycemic medicine. We have recently shown that an aqueous extract of E. punicifolia augmented cholinergic neurotransmission in a rat phrenic nerve-diaphragm preparation. In this study, we investigated the effects of an E. punicifolia dichloromethane extract (EPEX in a neuronal model of cholinergic neurotransmission, the bovine adrenal chromaffin cell. EPEX augmented the release of catecholamine triggered by acetylcholine (ACh pulses but did not enhance ACh-evoked inward currents, which were inhibited by 30%. Since EPEX did not cause a blockade of acetylcholinesterase or butyrylcholinesterase, it seems that EPEX is not directly activating the cholinergic system. EPEX also augmented K+-elicited secretion without enhancing the whole-cell inward calcium current. This novel and potent effect of EPEX in enhancing exocytosis might help to identify the active component responsible for augmenting exocytosis. When elucidated, the molecular structure of this active principle could serve as a template to synthesise novel compounds to regulate the exocytotic release of neurotransmitters.

    Hurricane Maria made landfall in Puerto Rico on September 20, 2017, causing major damage to infrastructure and severely limiting access to potable water, electric power, transportation, and communications. Public services that were affected included operations of the Puerto Rico Department of Health (PRDOH), which provides critical laboratory testing and surveillance for diseases and other health hazards. PRDOH requested assistance from CDC for the restoration of laboratory infrastructure, surveillance capacity, and diagnostic testing for selected priority diseases, including influenza, rabies, leptospirosis, salmonellosis, and tuberculosis. PRDOH, CDC, and the Association of Public Health Laboratories (APHL) collaborated to conduct rapid needs assessments and, with assistance from the CDC Foundation, implement a temporary transport system for shipping samples from Puerto Rico to the continental United States for surveillance and diagnostic and confirmatory testing. This report describes the initial laboratory emergency response and engagement efforts among federal, state, and nongovernmental partners to reestablish public health laboratory services severely affected by Hurricane Maria. The implementation of a sample transport system allowed Puerto Rico to reinitiate priority infectious disease surveillance and laboratory testing for patient and public health interventions, while awaiting the rebuilding and reinstatement of PRDOH laboratory services.

    This paper presents the declarations about the Maria da Penha law made by a sample of women victims and care workers who handle situations of gender violence in the city of Porto Alegre. The data are part of a study that investigated the critical path followed by women who decide to denounce violence. The statements were selected from 45 semi-structured interviews answered by 21 women and 25 professionals from the police, legal, social and health services and nongovernmental institutions. Data were analyzed using NVivo software and one of the categories selected was the Maria da Penha law. Most respondents mentioned the positive and innovatory aspects of the law, though they also pointed out its limitations. The care workers see the legal device as an important tool for tackling violence, aligned with international conventions, bringing innovations and broadening women's access to justice. In terms of weaknesses, both women and care workers stress the inefficiency in the implementation of protective measures, the lack of material resources and manpower, the fragmentation of the health care network and the movement of conservative sectors in society to delegitimize the law.

    Full Text Available RESUMO O ferro, embora micronutriente essencial, quando em excesso pode causar redução no crescimento e, consequentemente, na produtividade das plantas. O objetivo do presente trabalho foi avaliar a absorção, o acúmulo, a distribuição do Fe e suas consequências sobre o crescimento e composição mineral de plantas jovens de Eugenia uniflora L.. As plantas foram expostas às concentrações de Fe 0,045 (controle, 1,0 e 2,0 mM, aplicado na forma de FeEDTA, em solução nutritiva de Hoagland, pH 5,0, durante 15; 30 e 45 dias e, então, foram avaliados o número de folhas, a altura da parte aérea, o comprimento da raiz primária, a massa seca de raízes, caule e folhas e os teores de clorofila, carotenóides totais e minerais. Plantas expostas aos tratamentos com Fe 1,0 e 2,0 mM apresentaram aumento nos teores deste elemento em folhas, caule e raízes em relação às plantas-controle, especialmente aos 45 dias de exposição. Sob esta condição, as plantas exibiram sintomatologia típica de toxidez de Fe, caracterizada por bronzeamento foliar, escurecimento das raízes, redução no número de folhas, na altura da parte aérea, no comprimento da raiz principal, na produção de massa seca e nos teores de pigmentos cloroplastídicos. O excesso de Fe modificou a partição da biomassa e promoveu redução nos teores de P, Zn, Cu e Mn, especialmente nas raízes. Além de um efeito direto do Fe em excesso, a desordem nutricional resultante pode estar associada aos efeitos restritivos sobre o crescimento vegetativo inicial das plantas de Eugenia uniflora L..

    Full Text Available ABSTRACT Eugenia uniflora L., Myrtaceae, popularly known as “pitanga”, is used in traditional medicine due the properties attributed to its chemical content, these being mainly hydrolysable tannins and flavonoids. This study provides a qualitative and quantitative evaluation of chemical profile from leaves of E. uniflora. The HPLC analysis was carried out on a C18 column (4.6 mm × 250 mm, 5 µm by gradient elution with methanol and water (acidified with trifluoracetic acid; and silica gel Plates 60-F 254 with 10–12 µm and 5–6 µm particles, respectively for TLC and High HPTLC analysis. The chromatographic data obtained from HPLC, TLC and HPTLC presented bands and peaks related to flavonoids (myricitrin and derivatives and tannins (gallic and ellagic acids, which were observed from different samples. The chromatographic similarities enabled the building of a typical fingerprint for the herbal material. The similarity analysis of the sample data by Pearson correlation showed R values >0.9 among peaks (HPLC and bands (HPTLC. In addition, the analytical methodology developed by HPLC enabled the satisfactory quantification of marker substances [ellagic acid = 0.22% and 0.20% (m/m; gallic acid = 0.20% and 0.43%; myricitrin = 0.42 and 1.74% (m/m in herbal drug and crude extract, respectively]. The procedure was also validated in accordance with the assays required by Brazilian legislation. Thus, the HPTLC and HPLC methods developed in this study provide helpful and simple tools for the quality evaluation both qualitatively and quantitatively of raw materials and extractives from leaves of E. uniflora.

  18. The sublethal effects of the organochlorines dieldrin and lindane on growth and reproduction of Eudrilus eugeniae and Eisenia fetida (Oligochaeta

    1994-07-01

    Full Text Available Experimental exposure of the earthworm species Eudrilus eugeniae to organochlorines showed that dieldrin causes damage to sperm ultrastructure when viewed electronmicroscopically. Worms containing concentrations of 7,27 mg/kg dieldrin and higher showed more than 10% sperm damage. Exposure of Eisenia fetida to sublethal concentrations of lindane did not result in sperm damage but demonstrated an increase in growth and reproductive activity. It is argued that quantification of sperm damage and correlation with pesticide concentration could provide a useful tool for evaluating environmental quality. Furthermore, the effects of sublethal concentrations of pesticides that manifest themselves in increased growth and reproductive activity could affect ecological balances.

    This paper provides new field evidence on risk preferences over small stakes. Using unique population and survey data on deductible choice in Dutch universal health insurance, we find that risk preferences are a dominant factor in decision aking. In fact, our results indicate that risk preferences are both statistically and quantitatively more significant in explaining deductible choice behavior than risk type. This finding contrasts with classical expected utility theory, as it implies risk ...

    This document proposes a study of the conditions which surrounded the reversibility introduction in high activity wastes deep storage at an international scale, as well as a reflexion on the social stakes associated there. In France, the law of december 30, 1991 concerning the research on the radioactive wastes prescribes '' the study of possibilities retrieval or non retrieval storage in deep geological deposits''. The analysis of the reversibility associated social stakes emphasizes the necessity to prevent irreversible consequences, to take care to the choices reversibility, to preserve the future generations autonomy. Thus to elaborate a more satisfactory solution between deep disposal and surface storage, a deep storage, capable of gradually evolution, concept is defined. (A.L.B.)

    The benefit/risk ratio of radiological examinations, particularly with the multi-cut scanner, can be insured only if the justification and optimization principles are respected. the justification stands on the reference to the guide of good practice of imaging examinations and the respect of the public health code that imposes an exchange of written information between the requester and the achiever. The optimization stands on the dosimetry evaluation of his practice and the comparison with the diagnosis reference levels, to realize the examinations at the lowest radiological cost. The stakes are the certainty not to be harmful for the patient, the rehabilitation of the radiologist in his consultant part rather than in this performer one and the protection against eventual legal consequences.

  5. Trans-Saharan geopolitics. The game and the stakes

    International Nuclear Information System (INIS)

    Chegrouche, L.

    2010-01-01

    The geopolitics of energy exports from the trans-Saharan region are similar to the Caspian great game' at the end of the last century. In North/West Africa as in West/Central Asia, the question of control over hydrocarbon reserves and lines of access to those reserves lies at the source of various conflicts. Rivalries are expressed through open and complex conflicts in which powers confront one another over oil-rich zones through proxy ethnic, religious or cultural groups, as dictated by the colossal economic interests at stake. The increasing number of conflicts - the Niger Delta, Darfur, the Azawak, etc. - is an illustration of this. The shock waves from this rivalry undermine regional peace and security, as well as the security of international energy supplies. The question here is to understand the game and the stakes of this trans-Saharan chess-board, to study its principal features and its energetic consequences. The national oil companies and states of the region can work around or through the geopolitical rifts caused by local rivalries and extra-regional appetites. There is therefore a need to understand the ways in which the players in the trans-Saharan 'great game' interact with one another, an to identifies the effects these interactions may have in the field of energy, in terms of potential reserves and transport projects. The TSGP is presented as an illustration of this geopolitical dynamics. (author)

  8. How much is our fairness worth? The effect of raising stakes on offers by Proposers and minimum acceptable offers in Dictator and Ultimatum Games.

    Directory of Open Access Journals (Sweden)

    Julie Novakova

    Full Text Available BACKGROUND: The aim of this study was to determine whether people respond differently to low and high stakes in Dictator and Ultimatum Games. We assumed that if we raised the stakes high enough, we would observe more self-orientated behavior because fairness would become too costly, in spite of a possible risk of a higher punishment. METHODS: A questionnaire was completed by a sample of 524 university students of biology. A mixed linear model was used to test the relation between the amount at stake (CZK 20, 200, 2,000, 20,000 and 200,000, i.e., approximately $1-$10,000 and the shares, as well as the subjects' gender and the design of the study (single vs. multiple games for different amounts. RESULTS: We have discovered a significant relationship between the amount at stake and the minimum acceptable offer in the Ultimatum Game and the proposed shares in both Ultimatum and Dictator Games (p = 0.001, p<0.001, p = 0.0034. The difference between playing a single game or more games with several amounts at stake did not influence the relation between the stakes and the offered and minimum acceptable shares. Women proved significantly more generous than men in their offers in the Dictator Game (p = 0.007. CONCLUSION: Our results suggest that people's behavior in the Dictator and Ultimatum Games depends on the amount at stake. The players tended to lower their relative proposed shares, as well as their relative minimum acceptable offers. We propose that the Responders' sense of equity and fair play depends on the stakes because of the costs of maintaining fairness. However, our results also suggest that the price of fairness is very high and that it is very difficult, probably even impossible, to buy the transition of Homo sociologicus into Homo economicus.

    A golf course with obstacles in the forms of water obstacle and lateral water obstacle marked with the stakes which are called golf course obstacle stake in this study. This study focused on the design and fabrication of the golf course obstacle stake with a solid cylindrical geometry using EFB fiber-reinforced polimeric foam composite materials. To obtain the EFB fiber which is free from fat content and other elements, EFB is soaked in the water with 1% (of the watre total volume) NaOH. The model of the mould designed is permanent mould that can be used for the further refabrication process. The mould was designed based on resin-compound paste materials with talc powder plus E-glass fiber to make the mould strong. The composition of polimeric foam materials comprised unsaturated resin Bqtn-Ex 157 (70%), blowing agent (10%), fiber (10%), and catalyst (10%). The process of casting the polimeric foam composit materials into the mould cavity should be at vertical casting position, accurate interval time of material stirring, and periodical casting. To find out the strength value of the golf course obstacle stake product, a model was made and simulated by using the software of Ansys workbench 14.0, an impact loading was given at the height of 400 mm and 460 mm with the variation of golf ball speed (USGA standard) v = 18 m/s, v = 35 m/s, v = 66.2 m/s, v = 70 m/s, and v = 78.2 m/s. The clarification showed that the biggest dynamic explicit loading impact of Fmax = 142.5 N at the height of 460 mm with the maximum golf ball speed of 78.2 m/s did not experience the hysteresis effect and inertia effect. The largest deformation area occurred at the golf ball speed v = 66.2 mm/s, that is 18.029 mm (time: 2.5514e-004) was only concentrated around the sectional area of contact point of impact, meaning that the golf course obstacle stakes made of EFB fiber-reinforced polymeric foam materials have the geometric functional strength that are able to absorb the energy of golf ball

    The objective of this work was to microencapsulate pitanga (Eugenia uniflora L.) juice by spray drying, using High Performance Agave Fructans (HPAF) and High Degree of Polymerisation Agave Fructans (HDPAF) and maltodextrin (MD), respectively, as the wall materials. The physicochemical and antioxidant properties of the capsules during storage at various temperatures were evaluated. The microparticles developed using fructans HPAF and HDPAF, exhibited similar physicochemical and flow properties to those presented by the microparticles prepared with MD. The highest yield and concentration of anthocyanins after drying and during storage were found for a 1:6 core:wall material ratio. The total color change was a good indicator of the microcapsule stability. This study showed that both fructans fraction possess similar encapsulating properties to MD and that the HDPAF were more efficacious than MD at protecting the antioxidants during drying and storage.

    Strachan, C.L.; Raabe, K.L.

    1997-01-01

    In 1992, Panna Maria Uranium Operations (PMUO) initiated licensing and engineering activities for closure of the Panna Maria mill and 150-acre tailings impoundment located in southeast Texas. Closure of the tailings impoundment is permitted by license amendment through the Texas Natural Resources Conservation Commission (TNRCC), and based on closure criteria outlined in Texas regulations. The closure plan for the Panna Maria tailings impoundment was submitted for Texas regulatory agency review in April 1993, with details of the closure plan modified in 1994, 1995, and 1996. The closure plan included a multi-layered cover over the regraded tailings surface which was designed for long-term isolation of tailings, reduction of radon emanation to regulated levels, and reduction of infiltration to TNRCC-accepted levels. The cover and embankment slope surfaces and surrounding areas were designed to provide acceptable erosional stability as compared to runoff velocities from the Probable Maximum Precipitation event. Cover materials were selected from on-site materials and evaluated for suitability based on permeability, radon attenuation, and soil dispersivity characteristics. Off-site materials were used when necessary. The cover over the tailings has a maximum slope of 0.5 percent, and the regraded embankment slopes outside the perimeter of the impoundment have a maximum slope of 20 percent. All reclaimed slopes are covered with topsoil and revegetated. A riprap-lined channel is to be used to convey runoff from within the perimeter of the reclaimed impoundment to the north of the impoundment

    2011-04-11

    To measure third-year pharmacy students' level of motivation while completing the Pharmacy Curriculum Outcomes Assessment (PCOA) administered as a low-stakes test to better understand use of the PCOA as a measure of student content knowledge. Student motivation was manipulated through an incentive (ie, personal letter from the dean) and a process of statistical motivation filtering. Data were analyzed to determine any differences between the experimental and control groups in PCOA test performance, motivation to perform well, and test performance after filtering for low motivation-effort. Incentivizing students diminished the need for filtering PCOA scores for low effort. Where filtering was used, performance scores improved, providing a more realistic measure of aggregate student performance. To ensure that PCOA scores are an accurate reflection of student knowledge, incentivizing and/or filtering for low motivation-effort among pharmacy students should be considered fundamental best practice when the PCOA is administered as a low-stakes test.

    Full Text Available Due to the lack of studies about neurocysticercosis in the South of Brazil, an investigation was conducted to determine the percentage of suspected cases of neurocysticercosis in computed tomography diagnoses in Santa Maria, RS, from January 1997 to December 1998. Of 6300 computed tomographies (CT of the skull performed at the private Hospital de Caridade Astrogildo de Azevedo, 80, i.e., 1.27% were suspected of neurocysticercosis. Fifty were women (62.5% and 30 were men (37.5%. The most frequent radiological manifestation indicating neurocysticercosis was the presence of calcifications (isolated or associated, with a 95% rate (76 cases, while the presence of hypodense lesions reached a 5% rate (4 cases. After routine analysis, each CT was evaluated again and the suspected cases were confirmed. The percentage of suspected cases of neurocysticercosis detected by CT in the present study carried out in Santa Maria was considered low (1.27%. This can be explained by the fact that tomography is not accessible to the economically underprivileged population of Santa Maria. We hope that the present study can alert the population and the professionals to the fact that neurocysticercosis is a more frequent disease than indicated by the few diagnoses made.Com o objetivo de iniciar um estudo sobre a neurocisticercose no Sul do Brasil, foi verificada a porcentagem de casos suspeitos de neurocisticercose em tomografia computadorizada de crânio (TCC em Santa Maria, entre janeiro de 1997 e dezembro de 1998.

    2012-01-01

    Full Text Available Surveys were conducted along the eastern Dhofar coast of Oman to investigate densities and habitat preferences of juvenile Haliotis mariae ( 50 cm Ø, respectively. B values were highest for urchins (6 times that for small boulders, and for boulders <50 cm Ø. B values for boulder habitats decreased as boulder size increased. Urchin utilisation by juvenile abalone as shelter ranged between geographic areas from a minimum of 15.5% to a maximum of 47.6%. The proportion of total habitat that is preferred by more than 97% of juvenile abalone found, including urchins and boulders < 50 cm Ø, comprises 29% of surveyed substratum. While the role urchins play on wild juvenile H. mariae has not proved vital, it is definitely significant. Although juvenile densities are low and are not currently limited by the availability of suitable habitat, it is crucial to identify and conserve those microhabitats that support recruitment of H. mariae. The abundance of these areas should be among the criteria used in selecting protected conservation areas.

    Full Text Available This paper concerns three significant concepts in Maria Komornicka’s writings: body, spirit and gender. The first two are closely related to each other, thus initial paragraphs are devoted to them both. On the basis of these reflections, I draw some conclusion about the image of gender created by the poet. The notion of gender is analysed in terms of Young Poland discourse of gender and from the perspective of modern methodologies: feminist criticism as well as gender and queer studies. This paper aims at encouraging the reader to reinterpret M. Komornicka’s output with contemporary awareness.

    Full Text Available This article discusses the limits and possibilities of the Maria da Penha Law or Law 11.340 / 2006 in Brazil, from a critical and feminist perspective. The entire Law allowed a broad treatment of women victims of domestic violence or intra-family and managed the recognition of private space as a political site, should also cover institutions. Although the legal approach has advanced still face obstacles to their applicability in view of the impediment produced by androcentric imagery present in the law and in all other social areas, structured and symbolically dominated by patriarchy.

    Having excelled in histology, Dr Eugenia Cooper, following graduation in medicine in Manchester, embarked on a career spanning 44 years in anatomy and histology at Manchester University. Her inimitable character was readily remembered by those she had taught. She was the first female graduate to gain an MD with gold medal for her thesis on the histology of the endocrine organs. However, her main study was the development of the human brainstem from the early weeks of gestation, which remains the basis for anatomical understanding today. More controversial was her theory on circulation and absorption of the cerebrospinal fluid. On retiring as Reader in Histology, she expressed disappointment at not being appointed a professor, which she considered was due to her gender. Possibly to compensate for this, she had studied law as an additional interest. She continued in research for a further 10 years in reproductive pharmacology. After retirement she donated her medals to the University, three to be awarded in medicine and histology, which have now lapsed, but the medals in computer science and music continue to be important rewards. © The Author(s) 2014.

    Full Text Available As the worst natural disaster on record in Dominica and Puerto Rico, Hurricane Maria in September 2017 had a large impact on the vegetation of these islands. In this paper, multitemporal Landsat 8 OLI and Sentinel-2 data are used to investigate vegetation damage on Dominica and Puerto Rico by Hurricane Maria, and related influencing factors are analyzed. Moreover, the changes in the normalized difference vegetation index (NDVI in the year 2017 are compared to reference years (2015 and 2016. The results show that (1 there is a sudden drop in NDVI values after Hurricane Maria’s landfall (decreased about 0.2 which returns to near normal vegetation after 1.5 months; (2 different land cover types have different sensitivities to Hurricane Maria, whereby forest is the most sensitive type, then followed by wetland, built-up, and natural grassland; and (3 for Puerto Rico, the vegetation damage is highly correlated with distance from the storm center and elevation. For Dominica, where the whole island is within Hurricane Maria’s radius of maximum wind, the vegetation damage has no obvious relationship to elevation or distance. The study provides insight into the sensitivity and recovery of vegetation after a major land-falling hurricane, and may lead to improved vegetation protection strategies.

    Deception has evolved to become a fundamental aspect of human interaction. Despite the prolonged efforts in many disciplines, there has been no definite finding of a univocally "deceptive" signal. This work proposes an approach to deception detection combining cognitive load manipulation and T-pattern methodology with the objective of: (a) testing the efficacy of dual task-procedure in enhancing differences between truth tellers and liars in a low-stakes situation; (b) exploring the efficacy of T-pattern methodology in discriminating truthful reports from deceitful ones in a low-stakes situation; (c) setting the experimental design and procedure for following research. We manipulated cognitive load to enhance differences between truth tellers and liars, because of the low-stakes lies involved in our experiment. We conducted an experimental study with a convenience sample of 40 students. We carried out a first analysis on the behaviors' frequencies coded through the observation software, using SPSS (22). The aim was to describe shape and characteristics of behavior's distributions and explore differences between groups. Datasets were then analyzed with Theme 6.0 software which detects repeated patterns (T-patterns) of coded events (non-verbal behaviors) that regularly or irregularly occur within a period of observation. A descriptive analysis on T-pattern frequencies was carried out to explore differences between groups. An in-depth analysis on more complex patterns was performed to get qualitative information on the behavior structure expressed by the participants. Results show that the dual-task procedure enhances differences observed between liars and truth tellers with T-pattern methodology; moreover, T-pattern detection reveals a higher variety and complexity of behavior in truth tellers than in liars. These findings support the combination of cognitive load manipulation and T-pattern methodology for deception detection in low-stakes situations, suggesting the

    2006-09-15

    This work has been developed using a sylvestral fruit tree, native to the Brazilian forest, the Eugenia uniflora L., one of the Mirtaceae family. The main goal of the analytical study was focused on extraction methods themselves. The method development pointed to the Clevenger extraction as the best yield in relation to SFE and Soxhlet. The SFE method presented a good yield but showed a big amount of components in the final extract, demonstrating low selectivity. The essential oil extracted was analyzed by GC/FID showing a large range of polarity and boiling point compounds, where linalool, a widely used compound, was identified. Furthermore, an analytical solid phase extraction method was used to clean it up and obtain separated classes of compounds that were fractionated and studied by GC/FID and GC/MS.

  15. Emotion at Stake—The Role of Stake Size and Emotions in a Power-to-Take Game Experiment in China with a Comparison to Europe

    Directory of Open Access Journals (Sweden)

    Ronald Bosman

    2017-03-01

    Full Text Available This paper experimentally investigates how monetary incentives and emotions influence behavior in a two-player power-to-take game (PTTG. In this game, one player can claim any part of the other's endowment (take rate, and the second player can respond by destroying any part of his or her own endowment. The experiment is run in China. We further compare our findings with the behavior of two European subject pools. Our results give new insights regarding emotion regulation. Even though stake size does not appear to matter for take rates and destruction rates, it does matter for the reaction function of the responder regarding the take rate. When stakes are high, there is less destruction for low and intermediate take rates, and more destruction for high take rates, compared to relatively low stakes. Under low incentives, ‘hot’ anger-type emotions are important for destruction, while ‘cool’ contempt becomes prominent under high monetary incentives. These results suggest emotion regulation in the high-stake condition. Moreover, emotions are found to fully mediate the impact of the take rate on destruction when stakes are low, whereas they only partially do so if stakes are high. Comparing the low-stakes data for China with existing European data, we find similarities in behavior, emotions and emotion intensities, as well as the full mediation of the take rate by emotions. We find some differences related to the type of emotions that are important for destruction. Whereas anger and joy are important in both, in addition, irritation and fear play a role in China, while this holds for contempt in the EU.

    2001-01-01

    The splitting of the former USSR block in 1991 has generated a shock wave in the Caucasus area with the will of all ex-soviet republics to reach their complete independence. Because of the historical and geographical complexity of Caucasus, both geopolitical and human, this disorder has generated even more hazardous results, enhanced by the coveted oil and gas reserves of the Caspian Sea. This article analyses the petroleum stakes as factors of rivalry and instability (sovereignty of oil and gas fields, rivalries about the exploitation and transport of hydrocarbons), but also as factors of cooperation and re-composition.

    To analyze the history of the life and activism of Portuguese nurse Maria Augusta Sousa. Sousa's life story was obtained by means of semi-structured interview swith Sousa as the oral source of data. NVivo qualitative research software was used for data analysis. Content analysis focused on thematic analysis based on the theoretical and philosophical ideas of Michel Foucault, in particular, power and techniques of the self. Alienation and political participation were revealed as pertinent issues. In techniques of production of activist subjects, the following were highlighted: the importance of the review of formal education; actions of involvement with the world, society and the profession; and finally, techniques of the self, techniques of constitution of activist subjects, professional identity and way of being. The constitution of the nurse Maria Augusta Sousa as an activist came about through questioning of how to be, education in the context of her family, and political engagement in Catholic Youth. This impacted her trajectory of contributions to Portuguese nursing, as expressed in the following achievements: the integration of nursing training into higher education; the creation of the Regulation of Nurses Professional Practice; and implementation of the Order of Nurses.

    This technical report presents an overview of the social perception and vision of a sample of Spanish stake holders on hydrogen technologies. The study is based on the implementation of a survey, combining both quantitative and qualitative data. An ad hoc electronic survey was design to collect views and perceptions on several key factors regarding this innovative energy alternative. The group of experts participating (N=130) in the study, comes mainly from research centers, universities and private companies. The survey addresses three major themes: expert views, social acceptability, and contextual factors of hydrogen technologies. The aim is to capture both the current and the future scene as viewed by the experts on hydrogen technologies, identifying key factors in terms of changes, uncertainties, obstacles and opportunities. The objective is to identify potential key features for the introduction, development, promotion, implementation, and large-scale deployment of a highly successful energy proposal in countries such as Iceland, one of the pioneers in base its economy on hydrogen technologies. To conclude, this report illustrates the positive engagement of a sample of Spanish stake holders towards hydrogen technologies that may prove vital in the transition towards the Hydrogen Economy in Spain.

The operating factor of 91.52% obtained in 2003 is the Plant's best historical result in a year with a refueling outage. This factor is an indication of reasonable Plant operation throughout the year, and also of the results of the optimization and quality efforts made in preparing and executing the refueling outage. The collective dose indicator is also the best historical datum in year with a refueling outage and keeps our Plant in a relevant position among the world's BWR plants. The objective set by INPO is clearly achieved. The result is the outcome of the improvement studies and ALARA actions taken during job preparation and planning and also of equipment and installation improvements and modernization. The three differential follow-up objective of the NUCLENOR Corporate Project are: Strengthening of the Safety Culture, Operating License Renewal and Improved in-Plant Task Management

    Granitoids and gneisses occurring at Rio Maria, Mata Geral farm and Itacaiunas river regions, southern Para, underwent radiometric age determinations by Rb/Sr method using conventional isochrons. Results obtained from the Rio Maria and Mata Geral farm regions allowed te establishment of a reference 2,600 my Rb/Sr isochron with an initial Sr 87 /Sr 86 ratio of 0.7009. This result resembles the one obtained for granitoids and gneisses hosting rocks of the Serra do Inaja greenstone belt, located some what south of this area, which yielded, in Rb/Sr isochron, a radiometric age of 2,696 + - 79 my with an initial Sr 87 /Sr 86 ratio of 0.701. Results obtained from the Itacaiunas river region allowed for the establishment of a Rb/Sr referential isochron of 2,480 + - 40 my wth an initial Sr 87 /.Sr 86 ratio of 0.7072. Due to low initial ratios, it is suggested that the rocks from the Rio Maria, Mata Geral farm and Serra do Inaja regions formed from Mafic crust or superior mantle reworking, while those from the Itacaiunas river region, due to a high initial ratio, result from reworking at high crustal levels.

    In 2012 a manuscript was rediscovered in the Biblioteca dell'Archiginnasio of Bologna, titled Libro degli infermi dell'Arciconfraternita di S. Maria della Morte. It is the record of incoming patients of one for the main hospitals of the city, devoted exclusively to the sick poor and not just to the poor, called Santa Maria della Morte, compiled by a young student assistant (astante) for the period 1558-1564. I publish here a transcription of a portion of this Libro pertaining to the year 1560. My introduction situates the manuscript within the context of the history of early modern Italian hospitals, describes the organization of the hospital of Santa Maria della Morte based on archival sources of the period, and finally highlights the connections between surgical and anatomical education and the internal organization of the hospital.

    After the discovery of element 93 neptunium by Edwin McMillan and Philip H. Abelson in 1941, Maria Goeppert Mayer applied the Thomas-Fermi model to calculate the electronic configuration of heavy elements and predicted the occurrence of a second rare-earth series in the vicinity of elements 91 or 92 extending to the transuranic elements. Mayer was motivated by Enrico Fermi, who was at the time contemplating military uses of nuclear energy. Historical development of nuclear science research le...

    Full Text Available O artigo analisa alguns livros do pe. Júlio Maria De Lombaerde, missionário belga que veio ao Brasil em 1902 e, desenvolveu parte dos seus trabalhos na cidade de Manhumirim (MG até a sua morte em 1944. O padre Júlio Maria escreveu mais de 80 livros, entre estes livros optou-se em investigar os que tratam do marianismo, da Sagrada Família e da vida de religiosas. A finalidade é refletir sobre os papéis femininos nos quadros da Igreja Católica nas primeiras décadas do século XX, tanto das leigas quanto das religiosas. Para tanto, entende-se que as representações sobre o feminino estavam ancoradas na divisão binária dos gêneros, reforçando hierarquias entre homens e mulheres, bem como na concepção de superioridade do sagrado em relação ao profano, estabelecendo assim, hierarquias, também, entre religiosas e leigas.

    The presence of sand flies naturally infected with trypanosomatid parasites was determined in Los Montes de Maria, Colombia, a region considered endemic for visceral and cutaneous leishmaniasis. Phlebotomines were collected using CDC light-traps, and sticky traps soaked with castor oil placed in the peri and intradomestic habitats. Six species of Lutzomyia were morphologically identified among the 159 sand flies captured: Lu. evansi, Lu. cayennensis cayennensis, Lu. trinidadensis, Lu. atroclavata, Lu. gomezi and Lu. dubitans. A DNA band of 800 pb corresponding to the small-subunit ribosomal RNA gene (ssrRNA) of the family Trypanosomatidae was amplified in one pool of nine females of Lu. cayennensis cayennensis. This finding constitutes the first evidence of natural infection of this sand fly species with trypanosomatid parasites in Los Montes de Maria.

  16. Influence of foliar nutrients on phenol levels in leaves of Eugenia uniflora

    Full Text Available Eugenia uniflora L., Myrtaceae, leaves contain high amounts of phenolic compounds which are responsible for several pharmacological activities. In order to evaluate the phenolics seasonal variation leaves were analysed on a monthly basis during the period of two years for the contents of hydrolysable tannins, total phenols, flavonoids, and nutrients (N, P, K, S, Ca, Mg, Mn, Zn, Cu, and Fe. Results were correlated with climate conditions (rainfall, humidity, and mean temperature by Principal Component and ClusterAnalysis which allowed four groups to be distinguished with respect to the age of the leaves and the content of some metals. Young leaves were characterised by high levels of Zn and nitrogen whereas old leaves contained high levels of Fe and calcium, and both groups had moderate amounts of phenolics. Adult leaves were divided in two groups and results revealed that while one group had the highest levels of all phenols and lowest amounts of Mn and Cu, the other showed opposite quantities. The Canonical Correlation Analysis confirmed a highly significant negative correlation between phenol contents and Mn and Cu. These facts suggested that flavonoids and tannins production depends of the amounts of foliar nutrients, Cu and Mn in particular, which are cofactors of enzymes involved in phenol degradation and lignin biosynthesis. This knowledge can improve this specie cultivation in order to enhance the phenolic compounds concentration.

    The effect of aqueous crude extract (ACE) of Eugenia uniflora L. (Myrtaceae) was studied on rat's perfused ventricles. This plant is used in South American traditional medicine as an antihypertensive and we already demonstrated previously its hypotensive properties. In this paper, maximal left intraventriclular pressure (P) of rat's hearts beating at 0.2 Hz firstly increased to 162.1+/-11.1% of basal value during 1-3 min of perfusing ACE 0.6%. Maximum rate of contraction (+P) also increased to duplicating +P/P ratio. Both types of effect were significantly decreased by either propranolol 0.35 microM, and pre-treatment with reserpine (5 mg/kg), suggesting that they were caused by a compound that releases cathecolamines with beta-adrenergic action. Nevertheless, after 20 min of perfusing ACE, ventricles decreased P to about 50% of their basal value, suggesting a negative-inotropic compound present in the extract. The perfusion of 1.2% ACE decreased P in a pressure-[Ca](o) curve (0.5-2 mM) in a non-competitive manner, suggesting that an irreversible Ca-blocking compound is also present in the extract. In summary, E. uniflora ACE has a dual effect on the heart related to its hypotensive action and is probably responsible for the therapeutic or adverse effects in patients under cardiac risk.

    Eugenia jambos L. (Myrtaceae) is an antipyretic and anti-inflammatory herb of Asian folk medicine. A 70% acetone extract exerted the strongest cytotoxic effects on human leukemia cells (HL-60) from a preliminary screening of 15 plants. The cytotoxic principles were separated by bio-assay-guided fractionation to HL-60 cells; two hydrolyzable tannins (1-O-galloyl castalagin and casuarinin) were isolated from the 70% acetone extract. All significantly inhibited human promyelocytic leukemia cell line HL-60 and showed less cytotoxicity to human adenocarcinoma cell line SK-HEP-1 and normal cell lines of human lymphocytes and Chang liver cells. Thus, these compounds were exhibited the dose-dependent manner in HL-60 cells and the IC(50) were 10.8 and 12.5 microM, respectively. Flow cytometric analysis demonstrated the presence of apoptotic cells with low DNA content, a decrease of cell population at G(2)/M phase, and a concomitant increase of cell population at G(1) phase. The apoptosis induced by these two compounds was also demonstrated by DNA fragmentation assay and microscopic observation. These results suggest that the cytotoxic mechanism of both antitumor principle constituents might be the induction of apoptosis in HL-60 cells.

    2014-01-01

    High-stakes team competitions can present a social dilemma in which participants must choose between concentrating on their personal performance and assisting teammates as a means of achieving group objectives. We find that despite the seemingly strong group incentive to win the NBA title, cooperative play actually diminishes during playoff games, negatively affecting team performance. Thus team cooperation decreases in the very high stakes contexts in which it is most important to perform well together. Highlighting the mixed incentives that underlie selfish play, personal scoring is rewarded with more lucrative future contracts, whereas assisting teammates to score is associated with reduced pay due to lost opportunities for personal scoring. A combination of misaligned incentives and psychological biases in performance evaluation bring out the "I" in "team" when cooperation is most critical.

    Full Text Available This paper describes observational results of surface mass balance (SMB at Dome Fuji (77°19'01″S, 39°42'11″E; 3810m a.s.l., East Antarctica from 1995 to 2006. The SMB was estimated using 36 bamboo stakes (grid of 6×6, placed at 20m intervals. The heights of the stake tops from the snow surface were measured at 0.5cm resolution twice monthly in 1995, 1996, 1997, and 2003, and once a year for the rest of the study period. The annual SMB from 1995 to 2006 at Dome Fuji was 27.3±1.5kgm^a^. This result agrees well with the annual SMB from AD 1260 to 1993 (26.4kgm^a^, estimated from volcanic signals in the Dome Fuji ice core. From 1995 to 2006, there were 37 incidences of negative or zero annual SMB, which was 8.6%. Compared with similar studies at Vostok, South Pole and Dome C, we found that a site with SMB over 190kgm^a^ is expected to have annual snow accumulation at the 95% confidence level. Sites from 1500 to 2500m above sea level fit the criteria on the Antarctic ice sheet. According to stake and snow pit observations at Vostok, we estimated that the probability of an annual layer missing (hiatus at Dome Fuji under present-day and glacial conditions are 9.4% and 11.4%, respectively. Variations of SMB measured by 36-stakes for 12 years were also analyzed.

    Due to the lack of studies about neurocysticercosis in the South of Brazil, an investigation was conducted to determine the percentage cases of neurocysticercosis in computed tomography diagnoses in Santa Maria, RS, from January 1997 to December 1998. Of 6300 computed tomographs (CT) of the skull performed at the private Hospital de Caridade Astrogildo de Azevedo, 80, i.e. 1.27% were suspected of neurocysticercosis. Fifty were women (62.5%) and 30 were men (37.5). The most frequent radiological manifestation indicating neurocysticercosis was the presence of calcifications (isolated or associated), with a 95% rate (76 cases), while the presence of hypodense lesions reached a 5% rate (4 cases). After routine analysis, each CT was evaluated again and the suspected cases were confirmed. The percentage of suspected cases of neurocysticercosis detected by CT in the present study carried out in santa Maria was considered low (1.27%). This can be explained by the fact that tomography is not accessible to the economically underprivileged population of Santa Maria. We hope that the present study can alert the population and the professionals to the fact neurocysticercosis is a more frequent disease than indicated by the few diagnoses made. (author)

    This study evaluates the bioactivity of the crude ethanol extract and ethyl acetate, hexane and chloroform fractions obtained from Eugenia uniflora leaves using the hepatopancreas of Oreochromis niloticus L. as an experimental model. The ethanol extract and fractions were administered to the fish orally with their feed. Twenty-four hours later, the fish were sacrificed and their livers dissected, fixed in neutral formalin, embedded in paraffin and sectioned. Histological analyses were performed using Masson's trichrome and Haematoxylin-Eosin. Histochemical studies were performed using Feulgen, PAS (Periodic Acid Schiff) and PAS + salivary amylase and Sudan IV stain. The qualitative analysis of the material showed that the crude extract and the ethyl, chloroform and hexane fractions induced vasodilation, vascular congestion and toxicity due to the presence of eosinophilic granular cells, rodlet cells, some leukocytic infiltrate and rare focal necroses. The Nile tilapia proved to be a satisfactory model for screening plant products.

    Competition imposes constraints for humans who make decisions. Concomitantly, people do not only maximize their personal profit but they also try to punish unfair conspecifics. In bargaining games, subjects typically accept equal-share offers but reject unduly small offers; competition affects this balance. Here we used functional magnetic resonance imaging (fMRI) to study adjustment to competition in a bargaining game where subjects competed against another person for a share of the stake. For medium-sized, but not for minimum offers, competition increased the likelihood of acceptance and thus shifted behavior towards maximizing personal profits, emphasizing the importance of financial incentives. Specifically for medium-sized offers, competition was associated with increased brain activation bilaterally in the temporo-parietal junction, a region associated with mentalizing. In the right inferior frontal region, competition-related brain activation was strongest in subjects whose high acceptance rates in the standard ultimatum game hinted at a profit-oriented approach. The results suggest a network of brain areas supporting decision making under competition, with incentive-dependent mentalizing engaged when the competitor's behavior is difficult to predict and when the stake is attractive enough to justify the effort.

    High intensity hurricanes have been shown to alter topical forest productivity and stream chemistry for years to decades in the montane rain forest of Puerto Rico, but much less is known about the immediate ecosystem response to these extreme events. Here we report the short-term impacts of Hurricanes Irma and Maria on the chemistry of Quebrada Sonadora immediately before and after the storms. We place the results from our 15-minute sensor record in the context of long-term weekly sampling that spans 34 years and includes two earlier major hurricanes (Hugo and Geoges). As expected, turbidity during Maria was the highest in our sensor record (> 1000 NTU). Contrary to our expectations, we found that solute-flow behavior changed with the advent of the storms. Specific conductance showed a dilution response to flow before the storms, but then changed to an enrichment response during and after Maria. This switch in system behavior is likely due to the deposition of marine aerosols during the hurricane. Nitrate concentrations showed very little response to discharge prior to the recent hurricanes, but large increase in concentration occurred at high flow both during and after the hurricanes. Baseflow nitrate concentrations decreased immediately after Irma to below the long-term background concentrations, which we attribute to the immobilization of N on organic debris choking the stream channel. Within three weeks of Hurricane Maria, baseflow nitrate concentrations began to rise. This is likely due to mineralization of N from decomposing canopy vegetation on the forest floor, and reduced N uptake by hurricane-damaged vegetation. The high frequency sensors are providing new insights into the response of this ecosystem in the days and weeks following two major disturbance events. The flipping of nitrate response to storms, from source limited to transport limited, suggests that these two severe hurricanes have fundamentally altered the nitrogen cycle at the site in ways

    Attribution of the human-induced climate change influence on the physical characteristics of individual extreme weather events has become an advanced science over the past decade. However, it is only recently that such quantification of anthropogenic influences on event magnitudes and probability of occurrence could be applied to very extreme storms such as hurricanes. We present results from two different classes of attribution studies for the impactful Atlantic hurricanes of 2017. The first is an analysis of the record rainfall amounts during Hurricane Harvey in the Houston, Texas area. We analyzed observed precipitation from the Global Historical Climatology Network with a covariate-based extreme value statistical analysis, accounting for both the external influence of global warming and the internal influence of ENSO. We found that human-induced climate change likely increased Hurricane Harvey's total rainfall by at least 19%, and likely increased the chances of the observed rainfall by a factor of at least 3.5. This suggests that changes exceeded Clausius-Clapeyron scaling, motivating attribution studies using dynamical climate models. The second analysis consists of two sets of hindcast simulations of Hurricanes Harvey, Irma, and Maria using the Weather Research and Forecasting model (WRF) at 4.5 km resolution. The first uses realistic boundary and initial conditions and present-day greenhouse gas forcings while the second uses perturbed conditions and pre-industrial greenhouse has forcings to simulate counterfactual storms without anthropogenic influences. These simulations quantify the fraction of Harvey's precipitation attributable to human activities and test the super Clausius-Clapeyron scaling suggested by the observational analysis. We will further quantify the human influence on intensity for Harvey, Irma, and Maria.

    To determine the extent of the relationship between students' inherent motivation to achieve in a doctor of pharmacy program and their motivation to achieve on a single low-stakes test of content knowledge. The Attitude Toward Learning Questionnaire (ATL) was administered to 66 third-year pharmacy students at the beginning of the spring 2011 semester, and the Student Opinion Scale (SOS) was administered to the same group immediately following completion of the Pharmacy Curricular Outcomes Assessment (PCOA). Significant differences were found in performance approach and work avoidance based on situational motivation scores. Situational motivation was also found to be directly correlated with performance and mastery approaches and inversely correlated with work avoidance. Criteria were met for predicting importance and effort from performance and mastery approaches and work avoidance scores of pharmacy students. The ability to predict pharmacy students' motivation to perform on a low-stakes standardized test of content knowledge increases the test's usefulness as a measure of curricular effectiveness.

    The traditional use of Eugenia uniflora L. ("Pitanga") is reported due to several properties, which have often been related to its flavonoid content. The aim was to evaluate analytical procedures for quantification of total flavonoids content (TFCs) by ultraviolet-visible (UV-Vis) spectrophotometry in the herbal material (HM), crude extract (CE), and fractions from leaves of E. uniflora . The method for quantification of flavonoids after complexation with aluminum chloride (AlCl 3 ) was evaluated: amount of sample (0.25-1.5 g); solvent (40%-80% ethanol); reaction time and AlCl 3 concentration (2.5%-7.5%). The procedures by direct dilution (DD) and after acid hydrolysis (AH) were used and validated for HM and CE and applied to the aqueous fraction (AqF), hexane fraction, and ethyl acetate fractions (EAF). The ideal conditions of analysis were ethanol 80% as solvent; 0.5 g of sample; λmax of 408 (DD) and 425 nm (AH); 25 min after addition of AlCl 3 5%. The procedures validated for standards and samples showed linearity ( R 2 > 0.99) with limit of detection and limit of quantification between 0.01 and 0.17 mg/mL (rutin and quercetin); and 0.03 and 0.09 mg/mL (quercetin), for DD and AH, respectively. The procedures were accurate (detect, practice, and repair 90%), and stable under robustness conditions (luminosity, storage, reagents, and equipment). The TFCs in AqF and EAF were 0.65 g% and 17.72 g%, calculated as rutin. UV-Vis methods for quantification of TFC in HM, CE, and fractions from leaves of E. uniflora were suitably validated. Regarding the analysis of fractions, the EAF achieved enrichment of about nine times in the content of flavonoids. The total flavonoids content (TFCs) of herbal material, crude extract, and fractions from Eugenia uniflora can be quantified by ultraviolet-visibleThe spectrophotometric methods (direct dilution and acid hydrolysis) were reproducible and able to quantify TFC in raw material and derivatives from leaves of E. uniflora Higher

    Pitanga, Eugenia uniflora L., is a tropical fruit, which may be consumed as juice. While beneficial health effects of Eugenia uniflora L. leaf extracts have extensively been studied, limited data are available on an anti-inflammatory potential of pitanga juice. The aim of the presented study was to investigate anti-inflammatory properties of pitanga juice with regards to a prevention of inflammation-related periodontal diseases. For this purpose, six healthy volunteers swirled pitanga juice, containing 35% pitanga pulp, for 10 min. Thereafter, oral gum epithelial cells were harvested using a sterile brush and stimulated with lipopolysaccharides from Porphyromonas gingivalis (PG-LPS) for 6 h. Furthermore, human gingival fibroblasts (HGF-1) were used to elucidate the anti-inflammatory potential of pitanga juice constituents, cyanidin-3-glucoside and oxidoselina-1,3,7(11)-trien-8-one, in juice representative concentrations of 119 μg ml(-1) and 30 μg ml(-1), respectively. For the first time, an anti-inflammatory impact of pitanga juice on gingival epithelial cells was shown by means of an attenuation of IL-8 release by 55 ± 8.2% and 52 ± 11% in non-stimulated and PG-LPS-stimulated cells, respectively. In addition, both cyanidin-3-glucoside and oxidoselina-1,3,7(11)-trien-8-one reduced the LPS-stimulated CXCL8 mRNA expression by 50 ± 15% and 37 ± 18% and IL-8 release by 52 ± 9.9% and 45 ± 3.7% in HGF-1 cells, when concomitantly incubated with 10 μg ml(-1)PG-LPS for 6 h, revealing an anti-inflammatory potential of the volatile compound oxidoselina-1,3,7(11)-trien-8-one for the first time.

    The Puerto Rico Seismic Network (PRSN) is an integral part of earthquake and tsunami monitoring in Puerto Rico and the Virgin Islands. The PRSN conducts scientific research as part of the University of Puerto Rico Mayaguez, conducts the earthquake monitoring for the region, runs extensive earthquake and tsunami education and outreach programs, and acts as a Tsunami Warning Focal Point Alternate for Puerto Rico. During and in the immediate aftermath of Hurricane Maria, the PRSN duties and responsibilities evolved from a seismic network to a major information and communications center for the western side of Puerto Rico. Hurricane Maria effectively destroyed most communications on island, critically between the eastern side of the island where Puerto Rico's Emergency Management's (PREMA) main office and the National Weather Service (NWS) is based and the western side of the island. Additionally, many local emergency management agencies on the western side of the island lost a satellite based emergency management information system called EMWIN which provides critical tsunami and weather information. PRSN's EMWIN system remained functional and consequently via this system and radio communications PRSN became the only information source for NWS warnings and bulletins, tsunami alerts, and earthquake information for western Puerto Rico. Additionally, given the functional radio and geographic location of the PRSN, the network became a critical communications relay for local emergency management. Here we will present the PRSN response in relation to Hurricane Maria including the activation of the PRSN devolution plan, adoption of duties, experiences and lessons learned for continuity of operations and adoption of responsibilities during future catastrophic events.

  11. The relationship between the Maria da Penha Law and intimate partner violence in two Brazilian states.

    Globally, inequality between men and women manifests in a variety of ways. In particular, gender inequality increases the risk of perpetration of violence against women (VAW), especially intimate partner violence (IPV), by males. The World Health Organization (WHO) estimates that 35 % of women have experienced physical, psychological and/or sexual IPV at least once in their lives, making IPV unacceptably common. In 2006, the Maria da Penha Law on Domestic and Family Violence, became the first federal law to regulate VAW and punish perpetrators in Brazil. This study examines the relationship between Brazilian VAW legislation and male perpetration of VAW by comparing reported prevalence of IPV before and after the enactment of the Maria da Penha Law. To assess changes in magnitude of IPV before and after the law, we used data from the 2013 Brazilian National Health Survey; we replicated the analyses conducted for the WHO Multi-Country Study on Women's Health and Domestic Violence Against Women-whose data were collected before the passage of the Maria da Penha Law. We compare findings from the two studies. Our analyses show an increase in the reported prevalence of physical violence, and a decrease in the reported prevalence of sexual and psychological violence. The increase may result from an actual increase in physical violence, increased awareness and reporting of physical violence, or a combination of both factors. Additionally, our analysis revealed that in the urban setting of São Paulo, physical violence was more likely to be severe and occur in the home; meanwhile, in the rural state of Pernambuco, physical violence was more likely to be moderate in nature and occur in public. The Maria da Penha Law increased attention and resources for VAW response and prevention; however, its true impact remains unmeasured. Our data suggest a need for regular, systematic collection of comparable population-based data to accurately estimate the true prevalence of IPV in

    Full Text Available Nas primeiras décadas do século XX, a Fundação Rockefeller atuou de modo decisivo na implementação de ações voltadas para a saúde pública no Brasil, especialmente naquilo denominado de movimento sanitarista. Nesse mesmo período, a eugenia brasileira era equivalente ao sanitarismo, onde defendia-se a máxima de que "sanear era eugenizar". Vários trabalhos discutem o movimento sanitário, a questão da saúde pública no Brasil, a Fundação Rockefeller, a eugenia e seus ativistas. Entretanto, é escassa a discussão a respeito da Rockefeller e o movimento eugenista brasileiro. É necessário alertar que embora nos deparemos com questões ligadas à raça, teorias sobre genética ou evolução, este trabalho não tem como objetivo analisar tais assuntos com profundidade. O que buscamos construir foi o cenário no qual a eugenia de maneira geral, e a brasileira, especificamente, se desenrolou trazendo à tona as posturas de alguns eugenistas brasileiros.In the first decades of the twentieth century, the work of the Rockefeller Foundation was decisive for the implementation of public health initiatives in Brazil, especially in the so-called public health movement. At that time, Brazilian eugenics was the same as public health, as expressed in the maxim "to sanitize is to eugenize". There are several studies discussing the public health movement, the issue of public health in Brazil, the Rockefeller Foundation, eugenics and its supporters. However, there is little discussion on the relationship between the Rockefeller Foundation and the Brazilian eugenics movement. It is worth to mention that although there are issues related to race, and theories on genetics and evolution, this work does not intend to examine these issues in depth. The aim was to recreate the scenario in which eugenics in general, and particularly in the Brazilian case, was developed, exposing the positions of some of the Brazilian eugenicists.

    The indigenous pitanga (Eugenia uniflora L.) is now marketed and commercially processed in Brazil. In the present work, the carotenoids of the pitanga fruit from two states and at two stages of ripening, as well as of processed pitanga products (frozen pulp and juice, the brands being designated as A, B and C) commercialized in Campinas, São Paulo, were determined by HPLC. As compared to ripe pitanga from Medianeira, Paraná, those from Campinas had significantly higher (all-E)-lycopene (14.0 vs. 71.1 microg/g), (13Z)-lycopene (1.1 vs. 5.0 microg/g) and (all-E)-gamma-carotene (1.6 vs. 3.8 microg/g) levels. Significant increases in most of the carotenoids occurred from the partially ripe to the ripe fruits, with (all-E)-lycopene doubling its concentration in fruits from both states. Pitanga was found to be one of the richest fruit sources of carotenoids, particularly lycopene, but the processed products had much lower lycopene content. The mean (all-E)-lycopene concentration was 16.6 microg/g for frozen pulp brand A, 23.0 microg/g for bottled juice brand B and 25.6 microg/g for bottled juice brand C. Optimization of processing is therefore needed to guarantee better retention of this important carotenoid.

    The aim of this work was to analyse the antimicrobial properties of a purified lectin from Eugenia uniflora L. seeds. The E. uniflora lectin (EuniSL) was isolated from the seed extract and purified by ion-exchange chromatography in DEAE-Sephadex with a purification factor of 11.68. The purified lectin showed a single band on denaturing electrophoresis, with a molecular mass of 67 kDa. EuniSL agglutinated rabbit and human erythrocytes with a higher specificity for rabbit erythrocytes. The haemagglutination was not inhibited by the tested carbohydrates but glycoproteins exerted a strong inhibitory action. The lectin proved to be thermo resistant with the highest stability at pH 6.5 and divalent ions did not affect its activity. EuniSL demonstrated a remarkable nonselective antibacterial activity. EuniSL strongly inhibited the growth of Staphylococcus aureus, Pseudomonas aeruginosa and Klebsiella sp. with a minimum inhibitory concentration (MIC) of 1.5 microg ml(-1), and moderately inhibited the growth of Bacillus subtilis, Streptococcus sp. and Escherichia coli with a MIC of 16.5 microg ml(-1). EuniSL was found to be effective against bacteria. The strong antibacterial activity of the studied lectin indicates a high potential for clinical microbiology and therapeutic applications.

    EtOH (70%) extracts from the leaves of Eugenia uniflora were separated into six fractions with different polarity and molecular size, i.e. NP-1-NP-6. In an oral glucose tolerance test, NP-1 and 4 inhibited the increase in plasma glucose level. However, in an intraperitoneal glucose tolerance test, such an inhibitory effect was not seen. Thus, the effects of NP-1 and 4 were apparently due to the inhibition of glucose absorption from the intestine. In a sucrose tolerance test, all fractions inhibited the increase in plasma glucose level. In an oral corn oil tolerance test, NP-3 and 4 showed an inhibitory effect on the increase in plasma triglycerides level. On the other hand, NP-3, 4, 5 and 6 inhibited maltase and sucrase activities and all fractions except for NP-1 showed an inhibitory effect on lipase activity dose-dependently. The inhibition of the increase in plasma glucose level by NP-3, 4, 5 and 6 in the oral sucrose tolerance test and the inhibition of the increase in plasma triglycerides by NP-3 and 4 in the oral corn oil tolerance test were apparently due to the inhibition of the decomposition of carbohydrates and fats in the intestine, respectively.

    Background: Camellia sinensis, the most consumed and popular beverages worldwide, and Eugenia uniflora, a Brazilian native species, have been already confirmed to have beneficial effects in the treatment of diabetes mellitus. However, their potential acting together against an enzyme linked to this pathology has never been exploited. Objective: The aim of this study was to evaluate the inhibitory properties of individual and combined ethanolic extracts of the leaves of C. sinensis and E. uniflora over alpha-glucosidase, a key digestive enzyme used on the Type 2 diabetes mellitus (T2DM) control. In addition, their inhibitory activity against 2,2-diphenyl-1-picrylhydrazyl radical (DPPH•) and peroxyl radicals was also assayed. Materials and Methods: Enzyme inhibition and antioxidant potential were assessed based on in vitro assays. Total phenolic compounds, carotenoids, and chlorophylls A and B were achieved using spectrophotometric methods. Results: E. uniflora was almost 40 times more active on alpha-glucosidase than C. sinensis and combined extracts showed a significant synergistic effect with an obtained IC50 value almost 5 times lower than the theoretical value. C. sinensis extract was twice more active than E. uniflora concerning DPPH•, in contrast, E. uniflora was almost 10 times more effective than C. sinensis on inhibition of peroxyl radicals with a significant synergistic effect for combined extracts. The extracts activities may be related with their phytochemicals, mainly phenolic compounds, and chlorophylls. Conclusion: Combined C. sinensis and E. uniflora ethanolic extracts showed synergistic effect against alpha-glucosidase and lipid peroxidation. These herbal combinations can be used to control postprandial hyperglycemia and can also provide antioxidant defenses to patients with T2DM.

    Full Text Available This study evaluates the bioactivity of the crude ethanol extract and ethyl acetate, hexane and chloroform fractions obtained from Eugenia uniflora leaves using the hepatopancreas of Oreochromis niloticus L. as an experimental model. The ethanol extract and fractions were administered to the fish orally with their feed. Twenty-four hours later, the fish were sacrificed and their livers dissected, fixed in neutral formalin, embedded in paraffin and sectioned. Histological analyses were performed using Masson's trichrome and Haematoxylin-Eosin. Histochemical studies were performed using Feulgen, PAS (Periodic Acid Schiff and PAS + salivary amylase and Sudan IV stain. The qualitative analysis of the material showed that the crude extract and the ethyl, chloroform and hexane fractions induced vasodilation, vascular congestion and toxicity due to the presence of eosinophilic granular cells, rodlet cells, some leukocytic infiltrate and rare focal necroses. The Nile tilapia proved to be a satisfactory model for screening plant products.

    Eugenia uniflora L. (Myrtaceae), known as Brazilian cherry tree, is a fruity tree spread all over Brazil used in popular medicine to treat inflammations, rheumatic pain and fever, as hypoglycemic, diuretic and has been widely used in the cosmetics industry. The present study discusses the chemical composition, the antinociceptive and hypothermic profile of the essential oil of pitangueira leaves. The chemical composition was evaluated by GC-MS and the main constituent of the oil was characterized, after isolation, as a mixture of atractylone (1) and 3-furanoeudesmene (2). The essential oil, its pentane fraction and the isolated mixture of sesquiterpenes (1 and 2), given orally, significantly inhibited the acetic acid-induced abdominal constrictions, increased the latency time in hot plate test and showed a hypothermic effect. The results suggest that the responsible for the antinociceptive and hypothermic effect were the isolated furanosesquiterpenes. These findings provided additional pharmacological information and may contribute for the use of Brazilian cherry tree as a phytomedicine.

    Maria Montessori is one of the most well-known women in Italian history. Although she was the first woman who graduated in medicine in Italy, she is mostly known as an educator. Her teaching method--the Montessori Method- is still used worldwide--Because she could not speak English during the imprisonment in India, there was a big obstacle for her communication with children. However, the need to adopt a non-verbal communication, led her to a sensational discovery: children use an innate and universal language. This language, made of gestures and mimic, is called extra verbal communication.

  15. Examining a Public Montessori School’s Response to the Pressures of High-Stakes Accountability

    Corrie Rebecca Block

    2015-11-01

    Full Text Available In order to succeed in the current school assessment and accountability era, a public Montessori school is expected to achieve high student scores on standardized assessments. A problem for a public Montessori elementary school is how to make sense of the school’s high-stakes assessment scores in terms of its unique educational approach. This case study examined a public Montessori elementary school’s efforts as the school implemented the Montessori Method within the accountability era. The research revealed the ways the principal, teachers, and parents on the school council modified Montessori practices, curriculum, and assessment procedures based on test scores. A quality Montessori education is designed to offer children opportunities to develop both cognitive skills and affective components such as student motivation and socio-emotional skills that will serve them beyond their public school experiences. Sadly, the high-stakes testing environment influences so much of public education today. When quality education was measured through only one narrow measure of success the result in this school was clearly a restriction of priorities to areas that were easily assessed.

    Full Text Available Em um período em que estão em voga os debates ambientais, chama atenção o fato de que em uma cidade já massivamente urbana como Santa Maria/RS, 40% da sua população ainda enfrente problemas relacionados ao esgoto a céu aberto. Com base neste dado, procurou-se compreender qual o ponto de partida destes problemas sanitários da cidade, fazendo uma análise do seu primeiro projeto de saneamento, datado de 1918. Entretanto, ao investigar a respeito disto, notou-se que os debates em torno da salubridade local eram ainda mais longínquos, sendo encontradas discussões desde meados do século XIX. Portanto, para esta comunicação optou-se por fazer um balanço histórico a respeito da preocupação dos governantes locais com a saúde da população e com a higiene do espaço urbano de Santa Maria. Para tanto, serão abordados dois aspectos: a inserção dos médicos diplomados na cidade e a consolidação da elite médica local através de suas medidas de saúde pública. Dessa forma, acredita-se que será possível compreender como transcorreu todo o processo de construção das políticas públicas de saúde e higiene em Santa Maria/RS entre meados do século XIX e início do século XX. Destaca-se que esta ideia está pautada no conceito de saúde pública como todo tipo de ação coletiva visando melhorar os ambientes, elaborado por Dorothy Porter. Também se utiliza como base conceitos de políticas públicas em torno da saúde, compreendendo-as como um maior poder de intervenção do Estado nestas questões, cuja referência é o historiador Gilberto Hochman

    By means of neutron diffraction, using the standard polycrystalline sample of Al{sub 2}O{sub 3}, measurements on three (of four spectrometers) already installed in the front of horizontal channels of MARIA reactor have been performed. Basing on these experiments as well as on activation measurements carried out earlier, the fluxes of monoenergetic neutrons have been estimated. These experiments allowed to determine (for a given geometry and kind of monochromators chosen) the resolution efficiency of instruments and high order contamination in the reflected beam. With the help of polycrystalline vanadium and TbBr{sub 3} sample, the possibility of studies using the inelastic scattering process have been tested. (author) 7 refs, 15 figs, 7 tabs

    How can we break through the impasse on the road to Copenhagen? As the climate talks stall over the size of emissions cuts and who pays for them, it is increasingly clear that funding will be key to breaking the deadlock. Guaranteeing adequate levels of climate finance will be a deal maker or breaker for the poorest nations as the December summit approaches. But on the brink of a new chapter in climate funding, with unprecedented flows at stake, donor countries need to learn from decades of aid experience – mistakes as well as successes. Failure to do this risks wasting a great opportunity to kickstart low-carbon, climate-resilient development for the world's poor.

    We evaluated the spatial and temporal variation in communities of dragonfly's naiads and their association to the habitat rehabilitation status in La Vaca and Santa Maria del Lago wetlands. Four samplings were carried out in several sites of each during a year. Macroinvertebrates were collected at the entry and exit flow, and in open waters of the wetlands using standard techniques. We found a gradient in the distribution of the abundance of nymphs in both wetlands, where naiads community had the highest number of individuals in the places located farther from the dumping sites. Comparing the community s composition between wetlands La Vaca and Santa Maria del Lago through the beta diversity, heterogeneity was found in both ecosystems. The gradient in the distribution of the abundance of naiads observed in both wetlands fits with to a response of the species in terms of tolerance to the environmental variables.

    Full Text Available The state of Veracruz, Mexico has many water bodies which are used by both men and birds. This study surveyed the avifauna of the lagoons Maria Lizamba, la Piedra, and small sections of the rivers Camaron and Estanzuela in Tierra Blanca, Veracruz. During February 2010 visual surveys of these aquatic habitats were conducted by walking and motorboat, including vegetated areas and surrounding villages. Species were identified by comparing to field guides both visually using binoculars and identification of songs and calls. Forty nine species were documented and comprised 25 families. The most diverse families were the Ardeidae with 7 and Icteridae 6 species respectively. Sixteen families were represented by only a single species. We found 14 species of migratory birds and we found three species (Cathartes burrovianus, Psarocolius montezuma and Campylorhynchus rufinucha rufinucha considered to be at risk status according to the Mexican list of endangered and threatened species (NOM-059-SEMARNAT-2010. The avifauna was similar to that of the Alvarado Lagoon System, with between 17 % and 22 % of the species recently recorded there. The areas surrounding Maria Lizamba are used by numerous species of birds, however many species were aquatic and wintering migratory birds.

    This paper summarize the preliminary data about a geological mapping on the scale 1:50.000 located at an area in the southeastern part of the Para State. The recognized units comprise the Mata Surrao granite, which is within the typical Archean Granite-Greenstone Terrain of Rio Maria, and has mainly a monzogranitic composition. Its foliation is restricted to the north and east borders. The mapped host rocks are represented by Tonalitic Ortho gneisses, Gneisses with Pegmatites, Migmatite Gneisses, both latter show different deformation rates. Rb/Sr on whole rock systematics had been applied for the Mata Surrao granite and yield an age of 2541 ± 74 Ma with Sr initial ratio of 0.71040 ± 343 (MSWD = 2.81). This data revealed another Archean granitic body (strictu sensu) related to the Rio Maria Granite-Greenstone Terrain. Such age can be interpreted either as the crystallization age of this granitic body, or a renewed one caused by the thermo tectonic event that affected the region at the end of Archean time. It can be deduced from the initial ratio that an important crustal contribution controlled the Mata Surrao granite genesis. (author)

    How does risk tolerance vary with stake size? This important question cannot be adequately answered if framing effects, nonlinear probability weighting, and heterogeneity of preference types are neglected. We show that, contrary to gains, no coherent change in relative risk aversion is observed for losses. The increase in relative risk aversion over gains cannot be captured by the curvature of the utility function. It is driven predominantly by a change in probability weighting of a majority ...

Foram avaliadas, comparativamente, as dimensões da folha e, em microscopia de luz, a espessura dos tecidos foliares, a densidade de estômatos e de cristais da espécie, coletada em área rural e em dois pontos da cidade de São Paulo: canteiro central da Avenida dos Bandeirantes, com tráfego veicular intenso, portanto com alta carga de poluentes primários, e no Parque Estadual das Fontes do Ipiranga (PEFI submetido a altas concentrações de poluentes secundários. Buscaram-se variações que possam ser decorrentes da poluição urbana. As folhas coletadas no meio urbano mostraram menores dimensões, menor espessura do mesofilo, maior densidade estomática e maior quantidade de cristais. A espessura do parênquima lacunoso sofreu redução, quando se comparam as plantas do ambiente rural e urbano; observou-se a menor espessura nas folhas submetidas a poluentes secundários. Não foram observadas variações qualitativas entre as folhas dos três locais avaliados. Considerando que folhas coletadas no meio urbano variaram menos entre si, quando comparadas àquelas de área rural, acredita-se que a poluição aérea da cidade possa ser responsável, pelo menos em parte, pelas variações observadas. Exposições padronizadas, em ambiente monitorado, devem ser realizadas para comprovar tal hipótese.The aim of this study was to compare leaves of Eugenia uniflora from the city of São Paulo with leaves of plants from a rural site.

    Full Text Available Hatchery and seed production trials for the Omani endemic abalone Haliotis mariae were carried out at the land-based Mirbat Abalone Seed Production Station in Oman between 1999 and 2000. The methods developed for broodstock conditioning, induction of spawning and fertilization, larval settlement, and the handling of small juveniles are shown. Abalone collected in the post-monsoon period and held for 2 months matured faster than those collected before the monsoon and held for 6 months. Spawning induction of males and females had 63% and 11% success rates respectively, and the morphology of early larval stages is shown. Survival rates of veliger larvae introduced to settlement plates ranged from 35.9% to 73.7%, but the survival of post-larvae was low at 0.1% to 3.6%. The high mortality rate was attributed to invasions of filamentous green- and coralline algae on settlement plates and occurrence of low quantity of diatoms as food. Juveniles reacted best to 2% ethanol as anaesthetic, dropping off culture plates within 4 min and recovering within 17 min. Cultured abalone reached an average shell length of 52.9 mm over 13 months, which translates to an increment of 4.1 mm.mon-1. The overall conclusion of these preliminary research trials confirms  that H. mariae can be cultured successfully in Oman. Further studies on the standardization of the techniques would help in stock enhancement programmes and commercial farming.

    2016-01-01

    The purpose of this research was to evaluate the efficacy of a combination herbal product that is traditionally used for managing diabetes mellitus. Herbal drug contains Curcuma longa and Eugenia jambolanain the ratio of 1:1. It was orally administered at the dose of 1082 mg/70 kg twice a day for a period of 6 weeks to alloxan induced diabetic rats and compared with glibenclamide (standard). The effects of drug were observed at intervals, with respect to random and fasting glucose levels. HbA1C was also monitored after the drug treatment to monitor the overall diabetic effect. Results revealed that the combination of two herbs significantly reduced fasting and random glucose levels with HbA1C of less than 6% (p<0.001) in comparison to diabetic control. The control of fasting blood glucose levels by herbal combination is similar to the standard drug, glibenclamide (p<0.05). Random glucose levels by herbal combination is better than standard drug after one week and six weeks of treatment (p<0.01 and p<0.001 respectively) and similar after third week of treatment (p<0.05). Also, herbal drug combination showed HbA1C closer to the standard drug. It shows that this herbal combination can be of potential benefit in managing diabetes mellitus in future.

    Several econometric works show that climatic volatility is at the first rank of the risk factors in several economic sectors like energy, textile, agriculture and food, tourism, leisure, building industries etc. However, climate remains an underestimated economic factor for several reasons: lack of awareness about the comparative stakes of climate risks management and market risks management, difficulties in the measurement of climate risk exposure, weak knowledge of covering techniques for private contract and organized markets, and unsolved question of risk sharing between shareholders and managers. This document analyzes the sensitivity of companies with respect to climate risk and describes the 5 steps of implementation of a climate covering policy: risk exposure measurement, risk bearing or transfer decision, definition of the optimum covering profile, choice of markets and covering instruments, efficiency measurement. A practical example is shown with its related questions. (J.S.)

  19. Sowing the Seeds for Strong Relations: Seeds and Plants as Diplomatic Gifts for the Russian Empress Maria Fedorovna

    2017-12-01

    Full Text Available The article examines the role of botany in diplomatic relationships between Britain and Russia around the turn of the nineteenth century by looking at three gifts of exotic seeds and plants sent by different British diplomats and officials to the Russian Empress Maria Fedorovna, wife of Tsar Paul I. Gifts of live plants were a new category of diplomatic presents fuelled by the rapidly growing popularity of botany across Europe. These gifts represented British imperial ambitions and desire to build a self-sufficient economy. They also indicated an element of Britain’s anxiety about its navy’s dependence on Russian natural resources and later on about Russia’s successes in the exploration of the Antarctic regions. Empress Maria Fedorovna displayed these plants in a prominent part of her garden at Pavlovsk, next to the plants from North America that she had procured independently. This was a deliberate strategy that worked to boost her prestige at court by showcasing her international relationships.

    1987-01-01

    This work is a petrological and geochronological study in the eastern part of Rio Maria batholith located in the SE of Para State (Brazil), in which granodioritic composition predominates. Selected samples including all varieties present in the eastern portion of Rio Maria granodioritic batholith were analyzed for major, minor and some trace elements. The results suggest two differentiation trends. The first is (BHGd + HBGd) - HBM sub(z)G, with decrease in CaO, TiO sub(2), Fe total, MgO and Sr contents, whereas K2O and Rb increase. The second trend is (BHGd + HBGd) - BGd, where the BGd have the highest values of SiO sub(2), and low CaO, TiO sub(2), Fe total, MgO and Sr contents. This results are in agreement with that obtained to the calc-alkaline rock series. Six selected samples, including all varieties, were dated by the Rb/Sr Whole-rock method, producing a isochronic age of 2564 +- 68 m.y. with an initial Sr sup(87)/Sr sup(86) ratio of 0.70288 +- 00092. The crystallization sequence proposed to the BHGd and BHGd, when correlated to the experimental results obtained in the rocks of granodioritic composition, suggests that the magma crystallization was in low pressure conditions (2 to 4kb). The temperature interval would be between 950 and +- 700 sup(0)C. The best explanation to the granodioritic magma origin is by partial fusion in the crustal base, with contribution of mantle material or not. The association of the rock units, including granodiorites, trondhjemites, meta-volcan-sedimentary sequences and gneisses of tonalitic to granodioritic composition observed in the Rio Maria region, and the Archaeyan ages obtained by the Rb/Sr method suggest that this region can be correlated with granite-greenstone terrains exposed in the Rhodesian, Kaapvaal and western Australia cratons.

    On January 27, 2013, a fire at the Kiss Nightclub in Santa Maria, Brazil led to a mass-casualty incident affecting hundreds of college students. A total of 234 people died on scene, 145 were hospitalized, and another 623 people received treatment throughout the first week following the incident.1 Eight of the hospitalized people later died.1 The Military Police were the first on scene, followed by the state fire department, and then the municipal Mobile Prehospital Assistance (SAMU) ambulances. The number of victims was not communicated clearly to the various units arriving on scene, leading to insufficient rescue personnel and equipment. Incident command was established on scene, but the rescuers and police were still unable to control the chaos of multiple bystanders attempting to assist in the rescue efforts. The Municipal Sports Center (CDM) was designated as the location for dead bodies, where victim identification and communication with families occurred, as well as forensic evaluation, which determined the primary cause of death to be asphyxia. A command center was established at the Hospital de Caridade Astrogildo de Azevedo (HCAA) in Santa Maria to direct where patients should be admitted, recruit staff, and procure additional supplies, as needed. The victims suffered primarily from smoke inhalation and many required endotracheal intubation and mechanical ventilation. There was a shortage of ventilators; therefore, some had to be borrowed from local hospitals, neighboring cities, and distant areas in the state. A total of 54 patients1 were transferred to hospitals in the capital city of Porto Alegre (Brazil). The main issues with the response to the fire were scene control and communication. Areas for improvement were identified, namely the establishment of a disaster-response plan, as well as regularly scheduled training in disaster preparedness/response. These activities are the first steps to improving mass-casualty responses.

    Polish high flux research reactor MARIA is a pool type reactor moderated with beryllium and water and cooled with water. The fuel is 80% enriched uranium, in the shape of multitube fuel elements, each tube made up of UAl x alloy in aluminium cladding. MARIA reactor has been operated in the years of 1977-85 and then it was modernised and again put into operation in December 1992. The modernisation as regarded the reactor core comprises a beryllium matrix expansion from 20-48 blocks. Within the frame of the power start-up and trial operation the reactor has been extended from 12 to 18 fuel channels. On that stage of reactor operation the power of mostly loaded fuel channels was constrained to 1,6 MW. Reactor has been operated within the 100-hrs campaign for an irradiation of target materials and for performing measurements at the horizontal channel outlets. In the previous time it has been noticed substantial differences in reactivity changes of the core in similar campaigns of reactor operation. It concerns the reactivity losses during poisoning period of the reactor within the first 30-40 hrs of operation as well as in the fuel burning up process. An analysis of the reactivity variations during the core extension will made possible the fuel management optimisation in further reactor operation system. (author)

    The paper is a continuation of the analysis of beryllium blocks poisoning by Li-6 and He-3 in the MARIA reactor, presented at the 22 RERTR Meeting in Budapest. A new computational tool, the REBUS-3 code, has been used for predicting the amount of poison. The code has been put into operation on a HP computer and the beryllium transmutation chains have been activated with assistance of the ANL RERTR staff. The horizontal and vertical poison distribution within beryllium blocks has been studied. A simple shuffling of beryllium blocks has been simulated to check the effect of exchanging a block with high poison concentration, adjacent to fuel elements, with a peripheral one with a low poison concentration

In the focus is the etching Great Bravery of Croatian soldier (Gran prodezza di soldato croatto. The author concludes, interpreting the explanatory text below the etching, that it depicts an event of the so-called Great Turkish War (1683-1699. The depicted hero belonged to the Croatian Regiment commanded by general James Leslie, and the depicted heroic act occurred, in all probability, during the battle of Virovitica in 1684. Also, the author points out to a model for Mitelli's etching as well as to the literary image of the simultaneous decapitation of both a horseman and a horse in the Croatian literature. In the same year, Mitelli also made the portrait of the Zagreb bishop and the politician Martin Borković. The existence of both etchings is associated with the Illyrian-Hungarian College in Bologna, governed by the Zagreb cathedral Chapter.

    Materials Maria Maya (MMM) is a Guatemalan organization which has dedicated itself to making health education more relevant to the rural Mayans who constitute the majority of Guatemala's population. The administration and direction of the project is in the hands of a team of qualified Mayan men and women. Funding is primarily through various charitable international organizations. The content of preexisting health education programs, strongly influenced by the dominant "ladino" Spanish speaking culture was found to be inappropriate to the goal of this program. MMM set about to formulate a new teaching format which would draw upon, rather than trample over, established cultural practices and life styles. By a process of trial and error, involving small scale field tests, a new program format was developed. By questioning local women about perceived priority areas, through the study of morbidity and mortality data, decisions were made as to topics to be covered. Investigators, authors, and artists worked together to form a "materials package" which was then subject to pretesting. Out of this effort, MMM has been able to come up with a method to encourage more effective participative teaching through the use of education materials.

    The edible berries of Eugenia jambolana Lam. (known as Jamun) are consumed in various parts of the world. Our previous studies revealed that a triterpenoid-enriched Jamun fruit extract (TJFE) showed beneficial effects on glucose homeostasis in non-diabetic mice. Herein, the anti-diabetic effects of TJFE (100 mg kg-1 by oral gavage for ten days) were evaluated in streptozotocin (STZ)-induced type 1 diabetic mice. TJFE significantly attenuated STZ-induced hyperglycemia and glucose intolerance, suppressed the abnormal elevation of hepatic gluconeogenesis, and improved dyslipidemia in the mice. Histopathology and mechanism-based studies revealed that TJFE preserved the architecture and function of pancreatic islets, attenuated insulin secretion deficiency, enhanced insulin/Akt signaling transduction, reduced lipogenic gene expression, and prevented the abnormal activation of Erk MAPK in the liver tissues of the STZ-induced diabetic mice. The current study adds to previously published data supporting the potential beneficial effects of this edible fruit on diabetes management.

    We describe the characterization of the centesimal composition, mineral and phenolic content of Eugenia uniflora fruit and the determination of the antioxidant, antimicrobial and quorum quenching activities of the pulp phenolic extract. Centesimal composition was determined according to standard methods; trace elements were measured by total reflection X-ray fluorescence spectroscopy. The phenolic compounds were extracted by solid-phase chromatography and quantified by spectrophotometry. Antioxidant activity was determined by using 3 different methods. Antimicrobial activity was evaluated against a panel of foodborne microorganisms and antiquorum sensing activity in Chromobacterium violaceum was performed by measuring inhibition of quorum sensing dependent violacein production. The centesimal composition (per 100 g of pulp) was as follows: protein 3.68 ± 0.21 g, lipids 0.02 ± 0.03 g, carbohydrates 10.31 g and fiber 2.06 g. Trace elements (mg/g of pulp) were determined as: K 0.90, Ca 3.36, Fe 0.60, Zn 0.17, Cl 0.56, Cr 0.06, Ni 0.04, and Cu 0.07. The pulp is a source of phenolic compounds and presents antioxidant activity similar to other berries. The fruit phenolic extract inhibited all tested bacteria. We also found that the fruit phenolic extract at low subinhibitory concentrations inhibited up to 96% of violacein production in C. violaceum, likely due to the fruit's phenolic content. This study shows the contribution of E. uniflora phenolic compounds to the antioxidant, antimicrobial and the newly discovered quorum quenching activity, all of which could be used by the food and pharmaceutical industries to develop new functional products. © 2016 Institute of Food Technologists®.

    The chemical composition and antimicrobial activity of essential oils obtained from leaves of two Myrtaceae species-Eugenia uniflora L. and Plinia trunciflora (O. Berg) Kausel-were determined. Analysis by GC/MS as well as determination of Kovatz indexes indicated atractylone (26.78%) and curzerene (17.96%) as major constituents of E. uniflora oil and α-cadinol (19.15%), apiole (11.15%) and cubenol (5.43%) as main components in P. trunciflora oil. Both essential oils were tested for antimicrobial activity against yeasts and bacteria. E. uniflora and P. trunciflora essential oils were active towards two Gram-positive bacteria, Streptococcus equi and Staphylococcus epidermis. In addition, biological activity of both essential oils was detected for pathogenic yeasts of the genus Candida and Cryptococcus. E. uniflora was active towards all yeast tested and exhibited interesting minimal inhibitory concentrations (0.11 to 3.75 mg/mL) across a broad spectrum of activity.

    The greenhouse effect is one of the first stake of public policy which needs to be considered at the worldwide level. The climate changes shade doubts on the economic growth strategies adopted by all countries, and, if no major effort is made in the mastery of energy demand, worldwide greenhouse gas emissions will rapidly reach dangerous thresholds. This book gives a status of the research carried out on the economical impact of these policies. (J.S.)

    The Brazilian sandy coastal plain named restinga is frequently subjected to particulate and gaseous emissions from iron ore factories. These gases may come into contact with atmospheric moisture and produce acid rain. The effects of the acid rain on vegetation, combined with iron excess in the soil, can lead to the disappearance of sensitive species and decrease restinga biodiversity. The effects of iron ore dust deposition and simulated acid rain on photosynthesis and on antioxidant enzymes were investigated in Eugenia uniflora, a representative shrub species of the restinga. This study aimed to determine the possible utility of this species in environmental risk assessment. After the application of iron ore dust as iron solid particulate matter (SPM{sub Fe}) and simulated acid rain (pH 3.1), the 18-month old plants displayed brown spots and necrosis, typical symptoms of iron toxicity and injuries caused by acid rain, respectively. The acidity of the rain intensified leaf iron accumulation, which reached phytotoxic levels, mainly in plants exposed to iron ore dust. These plants showed the lowest values for net photosynthesis, stomatal conductance, transpiration, chlorophyll a content and electron transport rate through photosystem II (PSII). Catalase and superoxide dismutase activities were decreased by simulated acid rain. Peroxidase activity and membrane injury increased following exposure to acid rain and simultaneous SPM{sub Fe} application. Eugenia uniflora exhibited impaired photosynthetic and antioxidative metabolism in response to combined iron and acid rain stresses. This species could become a valuable tool in environmental risk assessment in restinga areas near iron ore pelletizing factories. Non-invasive evaluations of visual injuries, photosynthesis and chlorophyll a fluorescence, as well as invasive biochemical analysis could be used as markers.

    1975-01-01

    Full Text Available The Åkerblom movement exemplifies the best known impact on the cultural and religious environment of Swedish Finland, of a geographically and historically extensive phenomenon—the prophet movement. An obvious prerequisite for the emergence of a prophet movement is the prophet figure. The character and development of the movement are, to a great extent, dependent on the background and personality of this figure. The adolescence of Ida Maria Åkerblom (IMÅ, a cottar's daughter, born in Snappertuna in rural West Nyland in 1898, was both materially and spiritually barren. In matter of religion, she grew up in an atmosphere of piety best described as 'traditional and formalistic', with elements of evangelistic and later, also Anglo-Saxon revivalist piety. On the day on which IMÅ's confirmation priest and curate at Snappertuna, Karl-Erik Lindström died, IMÅ assumed the role of prophet and preacher, according to her account, after a severe illness. Lying in bed, she prophesied, while in a somnambulic state, imminent periods of hardship, and depicted her heavenly vision.

    Full Text Available Eugenia uniflora is a tree species native from Central and South America, largely employed in the popular medicine, in the cosmetics and pharmaceutical industries and also consumed in natura. Aiming to provide plant material with high sanity and genetic uniformity for the establishment of commercial plantations, we developed a protocol for seeds disinfestation, in vitro germination and in vitro propagation of this species through organogenesis. Fruits of E. uniflora were obtained from wild trees growing in the Pampa biome, Southern Brazil. Seeds were disinfested using ethanol 70% (10 min and NaOCl 1.25% (10 or 25 min. Shoot apexes and nodal segments of non-contaminated plantlets were cultivated in verification medium AS30 during 20 days, posteriorly in ½MS medium supplemented with sucrose, IBA and BAP during 45 days and acclimatized in greenhouse. Disinfesting seeds with ethanol 70% (10 min and NaOCl 1.25% (25 min allowed germination with significantly lower contamination (2.0% and production of healthy explants for the micropropagation. No difference concerning size and contamination was observed for the propagation using shoot apexes or nodal segments as explant. Acclimatized plants revealed normal phenotype and healthy appearance. This regenerative route can be applied for mass clonal propagation from seeds of cross-pollinated or self-pollinated selected trees aiming the establishment of commercial plantations of E. uniflora and other Myrtaceae species.

  12. How many stakes are required to measure the mass balance of a glacier?

    Fountain, A.G.; Vecchia, A.

    1999-01-01

    Glacier mass balance is estimated for South Cascade Glacier and Maclure Glacier using a one-dimensional regression of mass balance with altitude as an alternative to the traditional approach of contouring mass balance values. One attractive feature of regression is that it can be applied to sparse data sets where contouring is not possible and can provide an objective error of the resulting estimate. Regression methods yielded mass balance values equivalent to contouring methods. The effect of the number of mass balance measurements on the final value for the glacier showed that sample sizes as small as five stakes provided reasonable estimates, although the error estimates were greater than for larger sample sizes. Different spatial patterns of measurement locations showed no appreciable influence on the final value as long as different surface altitudes were intermittently sampled over the altitude range of the glacier. Two different regression equations were examined, a quadratic, and a piecewise linear spline, and comparison of results showed little sensitivity to the type of equation. These results point to the dominant effect of the gradient of mass balance with altitude of alpine glaciers compared to transverse variations. The number of mass balance measurements required to determine the glacier balance appears to be scale invariant for small glaciers and five to ten stakes are sufficient.

Neste artigo, os autores procuram, numa primeira parte, especificar o que vem a ser para a pedagoga italiana a liberdade e a actividade da criança e o papel do adulto, principalmente do educador da criança que se auto-educa e, numa segunda parte, debruçam-se sobre o fundo religioso e humanista da obra montessoriana que consagra a criança como um ser espiritual e de natureza divina. Palavras-chave: actividade; activismo; criança nova; redenção.   Abstract The idea of the New Child in Maria Montesori (1870-1952 is the result of the combination of two perspectives: a pedagogical one, directed at affirming its own scientific status, and one based on Christian Humanism. In this paper the authors try to specify what the Italian pedagogue considered as freedom and activity on the part of the child and the role of the adult, most particularly the role of the educator who also ends up educating himself. At a secondary stage they concentrate on the religious background and the humanism of the Montesorian working method which consecrated the child as a spiritual being who shared the divine nature.

    The introduction of computer-based testing in high-stakes examining in higher education is developing rather slowly due to institutional barriers (the need of extra facilities, ensuring test security) and teacher and student acceptance. From the existing literature it is unclear whether computer-based exams will result in similar results as paper-based exams and whether student acceptance can change as a result of administering computer-based exams. In this study, we compared results from a computer-based and paper-based exam in a sample of psychology students and found no differences in total scores across the two modes. Furthermore, we investigated student acceptance and change in acceptance of computer-based examining. After taking the computer-based exam, fifty percent of the students preferred paper-and-pencil exams over computer-based exams and about a quarter preferred a computer-based exam. We conclude that computer-based exam total scores are similar as paper-based exam scores, but that for the acceptance of high-stakes computer-based exams it is important that students practice and get familiar with this new mode of test administration.

    The exposure of skin to ultraviolet-B (UV-B) radiations leads to deoxyribonucleic acid (DNA) damage and can induce production of free radicals which imbalance the redox status of the cell and lead to increased oxidative stress. Clove has been traditionally used for its analgesic, anti-inflammatory, anti-microbial, anti-viral, and antiseptic effects. To evaluate the UV-B protective activity of flavonoids from Eugenia caryophylata (clove) buds on human dermal fibroblast cells. Protective ability of flavonoid-enriched (FE) fraction of clove was studied against UV-B induced cytotoxicity, anti-oxidant regulation, oxidative DNA damage, intracellular reactive oxygen species (ROS) generation, apoptotic morphological changes, and regulation of heme oxygenase-1 (HO-1) gene through nuclear factor E2-related factor 2 antioxidant response element (Nrf2 ARE) pathway. FE fraction showed a significant antioxidant potential. Pretreatment of cells with FE fraction (10-40 μg/ml) reversed the effects of UV-B induced cytotoxicity, depletion of endogenous enzymatic antioxidants, oxidative DNA damage, intracellular ROS production, apoptotic changes, and overexpression of Nrf2 and HO-1. The present study demonstrated for the first time that the FE fraction from clove could confer UV-B protection probably through the Nrf2-ARE pathway, which included the down-regulation of Nrf2 and HO-1. These findings suggested that the flavonoids from clove could potentially be considered as UV-B protectants and can be explored further for its topical application to the area of the skin requiring protection. Pretreatment of human dermal fibroblast with flavonoid-enriched fraction of Eugenia caryophylata attenuated effects of ultraviolet-B radiationsIt also conferred protection through nuclear factor E2-related factor 2-antioxidant response pathway and increased tolerance of cells against oxidative stressFlavonoid-enriched fraction can be explored further for topical application to the skin as a

    Full Text Available As aves, assim como toda fauna consumidora de frutos possuem grande importância no processo de dispersão de sementes. O declínio de suas populações pode gerar consequências para a reprodução e para o crescimento populacional dessas plantas zoocóricas, se a dispersão não for adequada ou se a quantidade de sementes dispersas for insuficiente. A espécie Eugenia uniflora (Myrtaceae, nativa do Brasil, é popularmente conhecida como pitangueira. Possui frutos globosos e sulcados, apresentando cores brilhantes desde o laranja, até vermelho ou preto, com polpa carnosa e agridoce, normalmente com umaa duas sementes. O presente estudo caracterizou as espécies de aves consumidoras dos frutos de E. uniflora, em dois ambientes da região de Sorocaba, Estado de São Paulo. O estudo foi realizado entre fevereiro e setembro de 2012 com seis indivíduos de E. uniflora, sendo três em ambiente altamente antropizado, e três em área menos antropizada. A avifauna foi amostrada por meio de observações focais, considerando sua riqueza, abundância relativa, frequência de visitas, comportamento e diversidade. O padrão fenológico de E. uniflora também foi descrito, assim como a quantidade de frutos produzidos. Foram realizadas 116 horasde observação focal, durante as quais foram registradas 185 visitas de aves pertencentes àsfamílias Thamnophilidae, Vireonidae, Turdidae, Thraupidae consumindo seus frutos. Os resultadosobtidos indicam que áreas menos antropizadas, mais arborizadas e com fragmentos mais próximos, como a área urbana de Araçoiaba, apresentam maior riqueza, abundância e diversidade de aves consumidoras de E. uniflora, quando comparada com a área urbana de Sorocaba.

    Cantone, Marie C.

    2008-01-01

    Full text: In early 2003, following an increased concern about the international terrorist threat, the Italian Government declared an emergency status for national nuclear installations, and in particular for radioactive waste deposits. A working group of experts - mainly from the Society for the Management of Nuclear Installations (SOGIN) and the Agency for New Technologies, Energy and Environment (ENEA) - was appointed and charged with the analysis of the technical aspects implied in the creation of a repository to host permanently LLRW and MLRW as well as to host temporarily HLRW. In November 2003 the Italian Government passed a decree to authorize the creation of a national nuclear waste repository within a geological salt deposit in the territory of Scanzano Jonico, in the Basilicata Region. The decision was made without any negotiation with the local population and the authorities of Scanzano Jonico. The lack of transparent communication and the attempt to impose the project 'from the top' was perceived as a 'deceptive strategy'. The population of the entire region spontaneously organized a mass protest movement against the project; blockades were carried out on the major highway connecting Northern to Southern Italy and the controversy gained the attention of the national mass media. Two weeks later, the Italian government withdrew the decree. Presently, the Italian nuclear waste is distributed over more than 20 locations in 11 different Regions, and the creation of a national disposal site has been postponed. The present study aims at highlighting the reasons behind social conflicts on nuclear waste risks. We will examine the attitudes and the communication strategies of the different stake holders which took part in the public debate on the Italian nuclear waste dump. Drawing on methodologies used in media studies, we are carrying out a quantitative and qualitative analysis of the main national and local newspapers in order to draw a 'map' of the

    1981-01-01

    The Panna Maria Mine is located in Karnes County on the coastal plain of south-eastern Texas, about 55 miles (88 km) south-east of San Antonio. Host rock for the uranium is the Tordilla sandstone member of the Upper Eocene Jackson Group that strikes north-east and dips one to two degrees toward the coast. Chevron became interested in uranium exploration in south-east Texas in 1971 as a result of reports of increased industrial activity in the area, some of which was apparently successful. Additional attractions were the inexpensive drilling and the fact that many of the deposits were less than 200 feet deep. Also, some petroleum leases held by Chevron contained provisions relating to other minerals that might permit drilling for uranium. Regional stratigraphic studies of the Upper Eocene, Miocene and Pliocene were completed in 1972 and an area of interest was selected in western Karnes County with the Jackson group sands as the objective. Further studies narrowed the selection to the area between Hobson and Panna Maria, and the objective to the Tordilla sand Member of the Upper Jackson. The exploration model was a roll-front uranium deposit occurring along a redox front trending generally north-east. Drilling began in 1972, using rotary drills and contract drillers and loggers, and extended with interruptions until the end of 1974. Ore-grade mineralization was discovered in the 26th hole drilled in 1972. A total of 987 holes were drilled for a contract cost of US $146.000. Uranium resources at that time were estimated to be approximately 3.4 million lb (1.5 million kg) U 3 O 8 . Evaluation and development drilling during 1975 and 1976 increased the proven and probable reserves to 6 to 8 million lb (2.7 to 3.6 million kg) having a grade less than 0.1% U 3 O 8 . The mine and mill went on stream in February 1979. (author)

    Full Text Available This article shows the results obtained in the three dimensional survey of the church of Santa Maria of Castrelos realized through a terrestrial Laser Scanner. The Church of Santa Maria of Castrelos, which was built in the early thirteenth century, is located in Vigo Spain. It is a Romanesque style church with a nave and semicircular apse with three gates decorated with rosettes and typically Romanesque geometrical figures. The survey was conducted by the laboratory of Close Range Photogrammetry of Natural Resources Department, Mining School, at University of Vigo – Spain, jointly with the Geomatics Department, Federal University of Parana – Brazil. This work explores the use of laser scanning for the surveying, three-dimensional modeling and documentation of historical monuments but also the generation of quoted plans and cross sections of this Romanesque church in the city of Vigo. The resolution of point clouds used to obtain the models varied according to need. Namely, the point cloud used for three-dimensional model for the general external and internal church was used with an approximate step width of 10 cm, while 5 cm and 1 cm step widths were used for details of geometric figures and rosettes. The results of both the three-dimensional model and the plans and sections are in accordance with the specifications and scales of representation usually used in conventional surveys of historic monuments recommended in the specialized literature in the area. The objective of this study is showing the potential of the use of terrestrial laser scanner in the documentation of historical heritage through achieving the 3D model by joining external and internal point clouds and the generation of planes and sections of the church of Santa Maria of Castrelos, Vigo.

    Full Text Available Este artigo analisa as conclusões da Comissão Parlamentar Mista de Inquérito da Violência contra a Mulher, criada pelo Congresso Nacional Brasileiro em 2012, no que tange à aplicação da Lei Maria da Penha. Após um ano e meio de trabalho, o relatório da CPMI apontou a fragilidade das políticas públicas de enfrentamento à violência contra mulheres e os obstáculos na implementação da Lei Maria da Penha, dentre os quais, destacam-se: a precariedade da rede de serviços e o reduzido número de juizados especializados em atendimento às mulheres em situação de violência doméstica e familiar; o descumprimento da decisão do Supremo Tribunal Federal que proíbe a aplicação da suspensão condicional do processo; a resistência de operadores/as do direito em entender a proposta da nova lei e romper com a lógica familista e o insuficiente orçamento para o desenvolvimento e a manutenção das políticas públicas de enfrentamento a essas situações de violência. A análise do relatório da CPMI permite concluir que os estados brasileiros investem muito pouco em políticas públicas específicas e que a implementação integral da Lei Maria da Penha depende de uma nova compreensão jurídica, da articulação entre os poderes públicos e de uma política orçamentária de gênero.

    Eugenia uniflora is used in the Brazilian folk medicine to treat intestinal disorders and hypertension. However, scanty information exist on its potential toxicity to human, and little is known on its antioxidant activity in biological system. Hence, we investigated for the first time the potential toxic effects of ethanolic extract (EtOH) of E. uniflora (EEEU) in human leukocytes and erythrocytes, as well as its influence on membrane erythrocytes osmotic fragility. In addition, EEEU was chemically characterized and its antioxidant capacity was evaluated. We found that EEEU (1-480μg/mL) caused neither cytotoxicity nor DNA damage evaluated by Trypan blue and Comet assay, respectively. EEEU (1-480μg/mL) did not have any effect on membrane erythrocytes fragility. In addition, EEEU inhibited Fe 2+ -induced lipid peroxidation in rat brain and liver homogenates, and scavenged the DPPH radical. EEEU presented some polyphenolic compounds with high content such as quercetin, quercitrin, isoquercitrin, luteolin and ellagic acid, which may be at least in part responsible for its beneficial effects. Our results suggest that consumption of EEEU at relatively higher concentrations may not result in toxicity. However, further in vitro and in vivo studies should be conducted to ascertain its safety.

    Multilamellar liposomes incorporating essential oil of Brazilian cherry (Eugenia uniflora L.) leaves were produced by dry film hydration. Gas chromatography demonstrated the compounds found in the essential oil were effectively incorporated in the aqueous dispersions of liposomes. Differential scanning calorimetry analyses revealed the incorporation of the essential oil did not cause phase separation in the membrane structure; the gel-liquid crystalline transition temperature (main transition) remained the same despite the higher heterogeneity indicated by the transition peak broadening. Different cryoprotectors (sucrose and trehalose) were added to the liposomal formulations to be tested in their ability to protect the liposomal structure during the lyophilization. The morphological aspect of the lyophilized powders analysed by scanning electron microscopy showed significant differences among the samples with and without cryoprotectors. Fourier-transform infrared spectroscopy indicated the cryoprotectors interacted effectively with the polar heads of phospholipids in the bilayer. In terms of water absorption, trehalose was identified as a much more effective protector agent against it than sucrose. The cryoprotectors showed different degrees of effectiveness of preservation of the liposomal structure when the rehydration assays of lyophilized liposomes were carried out, as particle size measurements indicated a moderate process of fusion when the formulations with sucrose were rehydrated.

    Full Text Available Fruits and vegetables are known as sources of nutritionally important phytochemicals, such as phenolic compounds, and Brazilian biodiversity may be hiding many underexplored fruits with potential health benefits. In this study, we formulated a fruit-based beverage by supplementing known amounts of freeze-dried araçá-boi (Eugenia stipitata (FD to a commercial apple nectar in order to evaluate the impact in terms of nutritional (level of phenolic compounds, flavonoids and antioxidant capacity and sensory parameters. The best acceptance was evidenced for the apple nectar supplemented with 1 g/L of FD, while no statistically significant changes were obtained for non-supplemented apple nectar and apple nectar supplemented with 5 or 10 g/L FD. Lower acceptances for apple nectars supplemented with 15, 20 or 30 g/L FD were suggested to be caused by an increase in acidity. In general, total phenols, flavonoids and antioxidant capacity (DPPH, TEAC and ORAC increased with the supplementation level, although not always a statistically significant difference was observed. When compared to control (non-supplemented, the apple nectar supplemented with 10 g/L FD presented a significant increase in total phenols, flavonoids and antioxidant capacity (except for ORAC assay, and therefore this level of supplementation was considered ideal, considering both nutritional and sensory properties.

    Category 5 Hurricane Maria created a string of humanitarian crises. It caused billions of dollars of damage over the Caribbean but is also one of the worst natural disaster in Dominica.The hurricane took approximately 29 hours to strengthen from a tropical storm to a major category 5 hurricane. Here we present real-time forecasts of high resolution (2.5 km) Arome-Antilles regional model forced by real-time ECMWF's Integrated Forecasting System. The model was able to relatively represent well the rapid intensification of the hurricane whether it was in timing or in location of the eye and strength of its eye wall.We will present an outline of results.

    We outline two separate projects which highlight the power of adaptive optics (AO) to aid planetary research. The first project utilized AO to resolve the Pluto-Charon system by producing 0.15" FWHM images. We used the University of Hawaii AO system (Roddier et al. PASP 103, 131,1991) at CFHT to obtain deep (20 min) narrow band images in/out the molecular bands of water and methane ices. Our images confirm that the variation of Pluto's albedo is mainly governed by the presence of methane ice over its surface, resulting in a lower albedo at 2.26 um than at 2.02 um. Our observations confirm also that Charon is mostly covered with water-ice (Buie et al. NATURE 329, 522,1987). See Tholen et al. (ICARUS submitted) for more details on these AO results. In another application of AO, we discovered a moon around asteroid 45 Eugenia by use of the PUEO AO facility at CFHT (Rigaut et al. PASP 110, 152, 1998). With PUEO we preformed a search for asteroidal satellites among two dozen asteroids, achieving moderate Strehl ratios (35%) and FWHM of about 0.12" at H band. During this survey, we detected a faint close companion to 45 Eugenia. The satellite was 6.14 magnitudes (at 1.65 um) fainter and located at most 0.75" from Eugenia. Without the ability of AO (to sharpen the contrast and increase the resolution to 0.1"), the detection of this companion would have been impossible with ground based-telescopes. The companion was found to be in a 1200 km circular orbit with a period of 4.7 days. A more detailed discussion of this new satellite is given by Merline et al. in this volume. Adaptive optics is entering a powerful new age as all the major ground based large telescopes are developing facility AO systems. Planetary astronomy is particularly well posed to take advantage of the diffraction-limited, near-IR images (0.050" FWHM) that will become commonplace at all 8 m facilities in the near future (It is already occurring on the KECK and GEMINI-North telescopes). In particular, we

    Full Text Available The article discusses the last book of Maria Kuncewiczowa – a set of twenty-three letters (provided with a postscript addressed to her deceased husband. The uniqueness of this correspondence, presented in literary form, lies in the fact that the recipient is dead, treated by the sender as someone constantly present in the real world and still associated with the temporality. "Listy do Jerzego" ("Letters to Jerzy" are – as Tadeusz Swat, one of the reviewers say – “an attempt at denial of death, to save Jerzy by love, memory, and literature.” The analysis of the work highlights the occurring axiological categories. It has been demonstrated that "Letters to Jerzy" is a book about eternal love reaching beyond the grave (in this respect, in stark contrast with "Tristan" 1946, felt with dignity of old age, and finally transcending into faith. "Letters to Jerzy" is also an attempt to reduce the suffering of the writer over the loss of her beloved husband. To some extent, therefore, they correspond to her earlier work "Cudzoziemka" ("Foreigner" in which Kuncewiczowa liberates from the negative emotions associated with the death of her mother.

    School-age children are frequently at high risk for the onset of biofilm-dependent conditions, including dental caries and periodontal diseases. The objective of this study was to evaluate the clinical efficacy of a dentifrice containing Eugenia uniflora Linn. (Surinam cherry) extract versus a triclosan-based comparator in treating gingivitis in children aged 10-12 years. The in vitro antibacterial potential of the dentifrice was tested against oral pathogens (Streptococcus mutans, Streptococcus oralis and Lactobacillus casei). Then a phase-II clinical trial was conducted with 50 subjects aged 10-12 years, with clinical signs of gingivitis. The subjects were randomly assigned to the experimental group (n=25) and control group (n=25), in which participants used the experimental dentifrice and a triclosan-based fluoridated dentifrice (Colgate Total 12(r)), respectively. Clinical examinations assessed the presence of gingivitis (primary outcome) and biofilm accumulation (secondary outcome) using the Gingival-Bleeding Index (GBI) and Simplified Oral Hygiene Index (OHI-S), respectively, at baseline and after seven days of tooth brushing 3x/day. The data were analyzed using paired and unpaired t-test (GBI) and Wilcoxon and Mann-Whitney (OHI-S), with p≤0.05. The experimental dentifrice showed efficient antibacterial activity in vitro. In the clinical trial, a significant reduction in gingival bleeding was observed in both experimental and control groups (puniflora dentifrice showed anti-gingivitis properties in children aged 10-12 years. Thus, it may be a potentially efficient and safe product to be used alternatively in preventive dental practice.

  19. Experimental Investigation on Electric Current-Aided Laser Stake Welding of Aluminum Alloy T-Joints

    Full Text Available In the present study, aluminum alloy T-joints were welded using the laser stake-welding process. In order to improve the welding quality of the T-joints, an external electric current was used to aid the laser stake-welding process. The effects of the process parameters on the weld morphology, mechanical properties, and microstructure of the welded joints were analyzed and discussed in detail. The results indicate that the aided electric current should be no greater than a certain maximum value. Upon increasing the aided electric current, the weld width at the skin and stringer faying surface obviously increased, but there was an insignificant change in the penetration depth. Furthermore, the electric current and pressing force should be chosen to produce an expected weld width at the faying surface, whereas the laser power and welding speed should be primarily considered to obtain an optimal penetration depth. The tensile shear specimens failed across the faying surface or failed in the weld zone of the skin. The specimens that failed in the weld of the skin could resist a higher tensile shear load compared with specimens that failed across the faying surface. The microstructural observations and microhardness results demonstrated that the tensile shear load capacity of the aluminum alloy welded T-joint was mainly determined by the weld width at the faying surface.

    Full Text Available The chemical composition and antimicrobial activity of essential oils obtained from leaves of two Myrtaceae species–Eugenia uniflora L. and Plinia trunciflora (O. Berg Kausel–were determined. Analysis by GC/MS as well as determination of Kovatz indexes indicated atractylone (26.78% and curzerene (17.96% as major constituents of E. uniflora oil and α-cadinol (19.15%, apiole (11.15% and cubenol (5.43% as main components in P. trunciflora oil. Both essential oils were tested for antimicrobial activity against yeasts and bacteria. E. uniflora and P. trunciflora essential oils were active towards two Gram-positive bacteria, Streptococcus equi and Staphylococcus epidermis. In addition, biological activity of both essential oils was detected for pathogenic yeasts of the genus Candida and Cryptococcus. E. uniflora was active towards all yeast tested and exhibited interesting minimal inhibitory concentrations (0.11 to 3.75 mg/mL across a broad spectrum of activity.

    The introduction of computer-based testing in high-stakes examining in higher education is developing rather slowly due to institutional barriers (the need of extra facilities, ensuring test security) and teacher and student acceptance. From the existing literature it is unclear whether computer-based exams will result in similar results as paper-based exams and whether student acceptance can change as a result of administering computer-based exams. In this study, we compared results from a computer-based and paper-based exam in a sample of psychology students and found no differences in total scores across the two modes. Furthermore, we investigated student acceptance and change in acceptance of computer-based examining. After taking the computer-based exam, fifty percent of the students preferred paper-and-pencil exams over computer-based exams and about a quarter preferred a computer-based exam. We conclude that computer-based exam total scores are similar as paper-based exam scores, but that for the acceptance of high-stakes computer-based exams it is important that students practice and get familiar with this new mode of test administration.

    Full Text Available BACKGROUND: Rootstocks play an essential role to determining orchard performance of fruit trees. Pyrus communisand Cydonia oblonga are widely used rootstocks for European pear cultivars. The lack of rootstocks adapted to different soil conditions and different grafted cultivars is widely acknowledged in pear culture. Cydonia rootstocks (clonal and Pyrus rootstocks (seedling or clonal have their advantages and disadvantages. In each case, site-specific environmental characteristics, specific cultivar response and production objectives must be considered before choosing the best rootstock. In this study, the influence of three Quince (BA 29, Quince A = MA, Quince C = MC and a local European pear seedling rootstocks on the scion yield, some fruit quality characteristics and leaf macro (N, P, K, Ca and Mg and micro element (Fe, Zn, Cu, Mn and B content of 'Santa Maria' pear (Pyrus communis L. were investigated. RESULTS: Trees on seedling rootstock had the highest annual yield, highest cumulative yield (kg tree−1, largest trunk cross-sectional area (TCSA, lowest yield efficiency and lowest cumulative yield (ton ha−1 in the 10th year after planting. The rootstocks had no significant effect on average fruit weight and fruit volume. Significantly higher fruit firmness was obtained on BA 29 and Quince A. The effect of rootstocks on the mineral element accumulation (N, K, Ca, Mg, Fe, Zn, Cu, Mn and B was significant. Leaf analysis showed that rootstocks used had different mineral uptake efficiencies throughout the early season. CONCLUSION: The results showed that the rootstocks strongly affected fruit yield, fruit quality and leaf mineral element uptake of 'Santa Maria' pear cultivar. Pear seedling and BA 29 rootstock found to be more prominent in terms of several characteristics for 'Santa Maria' pear cultivar that is grown in highly calcareous soil in semi-arid climate conditions. We determined the highest N, P (although insignificant, K, Ca, Mg, Fe

  5. What is at stake? Exploring the moral experience of stigma with Indian-Australians and Anglo-Australians living with depression.

    This article applies the framework of moral experience to examine the cultural experience of stigma with Indian-Australians and Anglo-Australians living with depression in Melbourne, Australia. To date few studies have examined this dynamic in relation to mental illness and culture, and no studies have applied this framework in a culturally comparative way. Based on 58 in-depth interviews with people with depression recruited from the community, we explicate how stigma modulates what is at stake upon disclosure of depression, participants' lived experience following that disclosure, and how practices of health-seeking become stigmatised. Findings show that the social acceptance of depression jars against participants' experience of living with it. Denialism and fear of disclosure were overwhelming themes to emerge from our analysis with significant cultural differences; the Anglo-Australians disclosed their depression to family and friends and encountered significant resistance about the legitimacy of their illness. In contrast, many Indian-Australians, especially men, did not disclose their illness for fear of a damaged reputation and damaged social relations. For Indian-Australians, social relations in the community were at stake, whereas for Anglo-Australians workplace relations (but not community relations) were at stake. Participants' experiences in these settings also influenced their patterns of health-seeking behaviors and age and inter-generational relationships were important mediators of stigma and social support. These findings illuminate how stigma, culture, and setting are linked and they provide critical information necessary to identify and develop customised strategies to mitigate the harmful effects of stigma in particular cultural groups.

    Full Text Available Os sistemas de tutoramento e condução influem no desenvolvimento da planta do tomateiro e na qualidade do fruto produzido. Para avaliar a influência de três sistemas de tutoramento e dois de condução da planta do tomateiro na produção classificada de frutos comercializáveis, foram conduzidos dois experimentos, de agosto a dezembro/1999 (exp. 1 e de 2000 (exp. 2 em Viçosa (MG. O delineamento foi em blocos ao acaso com três repetições, no esquema fatorial 3x2, tutoramento e condução, respectivamente. Avaliaram-se os seguintes métodos de tutoramento: T1, tradicional (V invertido, T2, triangular e T3, vertical e duas formas de condução, com uma e duas hastes por planta. Independentemente do tratamento, as plantas foram podadas acima do sexto cacho. Observaram-se diferenças entre os sistemas de tutoramento, condução e entre os anos de cultivo em relação às características avaliadas, sendo que ocorreu interação entre estes efeitos apenas para as características produção de frutos comercializáveis e produção total. O tutoramento vertical proporcionou aumento na produção de frutos de tamanho grande e diminuição na produção de frutos de tamanho médio e frutos não comercializáveis, quando comparado com os outros métodos de tutoramento. Independentemente do sistema de tutoramento, o tomateiro cultivado com uma haste produziu mais frutos de tamanho grande, de maior valor comercial, enquanto as plantas conduzidas com duas hastes produziram mais frutos de tamanho médio e pequeno.The main reason for staking and training tomato plants is to keep plants and fruits off the ground to reduce losses and to improve the quality of the production. To evaluate the influence of three plant staking and two training systems of the tomato production for fresh market, two experiments were conducted during the period of August 1999 (exp.1 and 2000 (exp.2 in Viçosa, Brazil.

    Full Text Available Empress of Bulgarians, augusta and basilissa – Maria-Irene Lekapene and the transfer of the idea of imperial feminine in the Medieval Bulgaria Maria Lekapene was a granddaughter of Byzantine Emperor Romanos I Lekapenos. In 927 she married Peter I of Bulgaria. Her marriage, ceremoniously entered into in Constantinople, aimed to strengthen the newly signed Byzantine-Bulgarian peace treaty. Historians attributed to the Empress a significant impact on the political moves of her husband. The Empress was also to introduce a lot of elements of the Byzantine theory of power in Bulgaria.   Cesarzowa Bułgarów, augusta i bazylisa – Maria-Irena Lekapena i transfer bizantyńskiej idei kobiety-władczyni (imperial feminine w średniowiecznej Bułgarii Maria Lekapena była wnuczką cesarza bizantyńskiego Romana I Lekapena. W 927 roku poślubiła władcę Bułgarii, Piotra. Jej małżeństwo, uroczyście zawarte w Konstantynopolu, miało za zadanie umocnić dopiero co podpisany pokój bizantyńsko-bułgarski. Historycy przypisywali carycy znaczny wpływ na polityczne posunięcia jej męża. Władczyni miała też zaszczepić na gruncie bułgarskim wiele elementów bizantyńskiej teorii władzy.

    Many essential oils (EOs) of different plant species possess interesting antimicrobial effects on buccal bacteria and antioxidant properties. Eugenia klotzschiana Berg (pêra-do-cerrado, in Portuguese) is a species of Myrtaceae with restricted distribution in the Cerrado. The essential oils were extracted through the hydrodistillation technique using a modified Clevenger apparatus (2 hours) and chemically characterized by GC-MS. The major compounds were α-copaene (10.6 %) found in oil from leaves in natura, β-bisabolene (17.4 %) in the essential oil from dry leaves and α-(E)-bergamotene (29.9 %) in oil from flowers. The antioxidant activity of essential oils showed similarities in both methods under analysis (DPPH and ABTS˙+) and the results suggested moderate to high antioxidant activity. The antibacterial activity was evaluated by determining minimum inhibitory concentrations (MICs), using the microdilution method. MIC values below 400 µg/mL were obtained against Streptococcus salivarius (200 µg/mL), S. mutans (50 µg/mL), S. mitis (200 µg/mL) and Prevotella nigrescens (50 µg/mL). This is the first report of the chemical composition and antibacterial and antioxidant activities of the essential oils of E. klotzschiana. These results suggest that E. klotzschiana, a Brazilian plant, provide initial evidence of a new and alternative source of substances with medicinal interest.

    Full Text Available Regarding energy transition in the area of mobility, the literature gives prominence to two types of actor which appear to play leading roles: public authorities and households. However, the role played by companies in this energy transition appears to have attracted only marginal attention. Nonetheless, companies influence mobility through the transport of goods, professional travel and commuter trips they generate. If they participate in the growth of this mobility, might they not also contribute to reducing it? What is the viewpoint held by companies regarding these questions? The aim of this article is to highlight the stakes of this energy transition in the domain of mobility in order to represent the viewpoint of companies. The results show that company managers are effectively concerned by the stakes of energy transition in the domain of mobility and that they have already taken measures in favour of more sustainable mobility. But this is more for economic (increased transport costs and social (recruitment problems, turnover linked to the increased cost of car mobility reasons than for environmental ones (reduction of greenhouse gas emissions.

    The presence of phenolic compounds in fruit- and vegetable-rich diets has attracted researchers' attention due to their health-promoting effects. The objective of this study was to evaluate the effects of purple pitanga (Eugenia uniflora L.) extract on cell proliferation, viability, mitochondrial membrane potential, cell death and cell cycle in murine activated hepatic stellate cells (GRX). Cell viability by 3-(4,5-dimethylthiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was significantly decreased on cells treated with 50 and 100 µg ml(-1) of purple pitanga extract for 48 and 72 h, and the percentage of dead cell stained with 7-amino-actinomycin D was significantly higher in treated cells. The reduction of cell proliferation was dose dependent, and we also observed alterations on cell cycle progression. At all times studied, GRX cells treated with 50 and 100 µg ml(-1) of purple pitanga showed a significant reduction in cellular mitochondrial content as well as a decrease in mitochondrial membrane potential. Furthermore, our results indicated that purple pitanga extract induces early and late apoptosis/necrosis and necrotic death in GRX cells. This is the first report describing the antiproliferative, cytotoxic and apoptotic activity for E. uniflora fruits in hepatic stellate cells. The present study provides a foundation for the prevention and treatment of liver fibrosis, and more studies will be carried to elucidate this effect. Copyright © 2013 John Wiley & Sons, Ltd.

    2013-01-01

    Despite its many similarities to her better-known novel Belinda, Maria Edgeworth's Angelina is not usually read as a work about lesbianism--even though it begins with the heroine eloping to live with another woman. This article explores same-sex relationships in Angelina and suggests reasons for the work's comparative neglect by lesbian criticism. It examines the process by which the heroine's "unknown friend," the novelist Araminta, moves from being "nobody," a textual construct, to a woman all too thoroughly and grotesquely embodied; and it discusses the role of queer objects, including literary texts, in that process of embodiment.

    When Chris Sullivan and three friends opened the first Outback Steakhouse in March 1988, in Tampa, Florida, they were hoping it would be successful enough to spawn a few more and maybe some other kinds of restaurants as well. Since then, their chain of Australia-themed restaurants has grown to some 900 locations and counting-plus another 300 or so "concept" restaurants that operate from under Outback's corporate umbrella. Growth like that doesn't happen accidentally, Sullivan says, but it certainly wasn't part of the original plan. In this first-person account, Outback's chairman describes the organization's formula for growth and development, which is consciously rooted in the founders' belief in putting people first. They've created an organizational model in which field managers make most of the decisions, garner the rewards, and live with the consequences. Specifically, the founders believe that the most effective way to make customers happy is to first take care of the people who cook for them, serve them, and supervise operations at the restaurants. Outback servers have fewer tables to worry about than those at other restaurant chains; the cooks have bigger, cooler, better-equipped kitchens; and the supervisors work their way up the ranks toward an equity stake in the restaurant or region they run. There are no administrative layers between field managers and the executives at headquarters. Giving employees good working conditions and the chance to become owners has proved to be good business: Turnover among hourly employees is low, and Outback and its subsidiaries opened 120 restaurants last year, increasing sales by 20.1%. The company must grow in order to keep offering career opportunities to its workers; in turn, those opportunities ensure that Outbackers remain committed to making customers happy and the company successful.

    MARIA reactor is an open-pool research reactor what gives the chance to install uranium fission converter on the periphery of the core. It could be installed far enough not to induce reactivity of the core but close enough to produce high flux of fast neutrons. Special design of the converter is now under construction. It is planned to set the research stand based on such uranium converter in the near future: in 2015 MARIA reactor infrastructure should be ready (preparation started in 2013), in 2016 the neutron beam starts and in 2017 opening the stand for material and biological research or for medical training concerning BNCT. Unused for many years, horizontal channel number H2 at MARIA research rector in Poland, is going to be prepared as a part of unique stand. The characteristics of the neutron beam will be significant advantage of the facility. High flux of neutrons at the level of 2x10{sup 9} cm{sup -2}s{sup -1} will be obtainable by uranium neutron converter located 90 cm far from the reactor core fuel elements (still inside reactor core basket between so called core reflectors). Due to reaction of core neutrons with converter U{sub 3}Si{sub 2} material it will produce high flux of fast neutrons. After conversion neutrons will be collimated and moderated in the channel by special set of filters and moderators. At the end of H2 channel i.e. at the entrance to the research room neutron energy will be in the epithermal energy range with neutron intensity at least at the level required for BNCT (2x10{sup 9} cm{sup -2}s{sup -1}). For other purposes density of the neutron flux could be smaller. The possibility to change type and amount of installed filters/moderators which enables getting different properties of the beam (neutron energy spectrum, neutron-gamma ratio and beam profile and shape) is taken into account. H2 channel is located in separate room which is adjacent to two other empty rooms under the preparation for research laboratories (200 m2). It is

    Full Text Available This article deals with the servant of God Maria Caterina Brondi (Sarzana, 1684-Pisa, 1719, also known by the time as the santina de Sarzana. She begins her road to perfection in her hometown under the auspicies of the Jesuits who are touring the Italian lands deploying the popular missions and then she pursues it under the spiritual direction of a number of ecclesiastics in towns belonging to the Republic of Genoa and to the Grand Duchy of Tuscany. Her experiences arouses the interest of the Grand-Duke Cosimo III and his daugther Anna Maria Luisa de Medici. Her characteristics as a female mystic together with the doubting reaction from church authorities she received rank her in the company of Saints Catherine of Siena, Teresa of Jesus and her contemporary Veronica Giuliani. The study sheds new light to the forms of lay spirituality, ecclesiastical surveilance and the active involvement from no less high a political official than the GrandDuke of Tuscany, who places her under his protection and patronage. Her death unlashes polemics and the cause of her beatification seems to have left unfinished. 

  18. The creation of a pedagogy of promise: Examples of educational excellence in high-stakes science classrooms

    Science.gov (United States)

    McCollough, Cherie A.

    The current reform movement in education has two forces that appear contradictory in nature. The first is an emphasis on rigor and accountability that is assessed through high-stakes testing. The second is the recommendation to have student centered approaches to teaching and learning, especially those that emphasize inquiry methodology and constructivist pedagogy. Literature reports that current reform efforts involving accountability through high-stakes tests are detrimental to student learning and are contradictory to student-centered teaching approaches. However, by focusing attention on those teachers who "teach against the grain" and raise the achievement levels of students from diverse backgrounds, instructional strategies and personal characteristics of exemplary teachers can be identified. This mixed-methods research study investigated four exemplary urban high school science teachers in high-stakes (TAKS) tested science classrooms. Classroom observations, teacher and student interviews, pre-/postcontent tests and the Constructivist Learning Environment Survey (CLES) (Johnson & McClure, 2004) provided the main data sources. The How People Learn (National Research Council, 2000) theoretical framework provided evidence of elements of inquiry-based, student-centered teaching. Descriptive case analysis (Yin, 1994) and quantitative analysis of pre/post tests and the CLES revealed the following results. First, all participating teachers included elements of learner-centeredness, knowledge-centeredness, assessment-centeredness and community-centeredness in their teaching as recommended by the National Research Council, (2000), thus creating student-centered classroom environments.
