Near-earth cosmic ray decreases associated with remote coronal mass ejections

Galactic cosmic ray (GCR) flux is modulated by both particle drift patterns and solar wind structures on a range of timescales. Over solar cycles, GCR flux varies as a function of the total open solar magnetic flux and the latitudinal extent of the heliospheric current sheet. Over hours, drops of a few percent in near-Earth GCR flux (Forbush decreases, FDs) are well known to be associated with the near-Earth passage of solar wind structures resulting from corotating interaction regions (CIRs) and transient coronal mass ejections (CMEs). We report on four FDs seen at ground-based neutron monitors which cannot be immediately associated with significant structures in the local solar wind. Similarly, there are significant near-Earth structures which do not produce any corresponding GCR variation. Three of the FDs are during the STEREO era, enabling in situ and remote observations from three well-separated heliospheric locations. Extremely large CMEs passed the STEREO-A spacecraft, which was behind the West limb of the Sun, approximately 2–3 days before each near- Earth FD. Solar wind simulations suggest that the CMEs combined with pre-existing CIRs, enhancing the pre-existing barriers to GCR propagation. Thus these observations provide strong evidence for the modulation of GCR flux by remote solar wind structures.

Otherworlds: fantasy and history in medieval literature

This book offers a new perspective on the otherworlds of medieval literature. These fantastical realms are among the most memorable places in medieval writing, by turns beautiful and monstrous, alluring and terrifying. Passing over a river or sea, or entering into a hollow hill, heroes come upon strange and magical realms. These places are often very beautiful, filled with sweet music and adorned with precious stones and rich materials. There is often no darkness, time may pass at a different pace, and the people who dwell there are usually supernatural. Sometimes such a place is exactly what it appears to be-the land of heart's desire-but, the otherworld can also have a sinister side, trapping humans and keeping them there against their will. Otherworlds: Fantasy and History in Medieval Literature takes a fresh look at how medieval writers understood these places and why they found them so compelling. It focuses on texts from England, but places this material in the broader context of literary production in medieval Britain and Ireland. The narratives examined in this book tell a rather surprising story about medieval notions of these fantastical places. Otherworlds are actually a lot less 'other' than they might initially seem. Authors often use the idea of the otherworld to comment on very serious topics. It is not unusual for otherworld depictions to address political issues in the historical world. Most intriguing of all are those texts where locations in the real world are re-imagined as otherworlds. The regions on which this book focuses, Britain, Ireland and the surrounding islands, prove particularly susceptible to this characterization.

South Atlantic Ocean cyclogenesis climatology simulated by regional climate model (RegCM3)

A detailed climatology of the cyclogenesis over the Southern Atlantic Ocean (SAO) from 1990 to 1999 and how it is simulated by the RegCM3 (Regional Climate Model) is presented here. The simulation used as initial and boundary conditions the National Centers for Environmental Prediction-Department of Energy (NCEP/DOE) reanalysis. The cyclones were identified with an automatic scheme that searches for cyclonic relative vorticity (zeta(10)) obtained from a 10-m height wind field. All the systems with zeta(10) a parts per thousand currency sign -1.5 x 10(-5) s(-1) and lifetime equal or larger than 24 h were considered in the climatology. Over SAO, in 10 years were detected 2,760 and 2,787 cyclogeneses in the simulation and NCEP, respectively, with an annual mean of 276.0 +/- A 11.2 and 278.7 +/- A 11.1. This result suggests that the RegCM3 has a good skill to simulate the cyclogenesis climatology. However, the larger model underestimations (-9.8%) are found for the initially stronger systems (zeta(10) a parts per thousand currency sign -2.5 x 10(-5) s(-1)). It was noted that over the SAO the annual cycle of the cyclogenesis depends of its initial intensity. Considering the systems initiate with zeta(10) a parts per thousand currency sign -1.5 x 10(-5) s(-1), the annual cycle is not well defined and the higher frequency occurs in the autumn (summer) in the NCEP (RegCM3). The stronger systems (zeta(10) a parts per thousand currency sign -2.5 x 10(-5) s(-1)) have a well-characterized high frequency of cyclogenesis during the winter in both NCEP and RegCM3. This work confirms the existence of three cyclogenetic regions in the west sector of the SAO, near the South America east coast and shows that RegCM3 is able to reproduce the main features of these cyclogenetic areas.

Current and future shopping conditions in Sälen

Going from having bought the most essential at the small shops close to home, better communications and an increasingly consumption oriented lifestyle has created a change in shopping behavior and has led to phenomenon such as shopping centres and more. These are constantly being built in Sweden: in the cities, outside the cities and more recently even in small cities -small cities as for one reason or another have access to a larger customer base which can have businesses to flourish economically. During the first decade of the 21st century, shopping centres have been established along the Swedish/Norwegian border. Since the Norwegian Krone is much stronger than the Swedish Krona Norwegians save a great deal of money on going to Sweden to shop. During the shopping trips to Sweden, it is mostly alcohol, meat, tobacco and candy that are being bought. However, other products such as clothing, technology, household appliances and more are also being purchased, all to save money on the trip. Together these cross border shoppers spent 11, 6 billion in Sweden during the year of 2010. This gives an average spending of approximately 10 900 SEK per cross border shopper on annual basis. Nordby, Töcksfors and Charlottenberg (small cities located in southwestern Sweden) are places characterized by Norwegian cross border shopping. Together, they generate billions every year and this only seems to increase. These places are relatively small in size but have prominent attributes such as proximity to the Norwegian border. Apart from these resorts and shopping centres, there are few or none similar places near the Norwegian border in the rest of Sweden. However, a place which is geographically well located and has a relatively large Norwegian and Swedish customer base is the ski resort of Sälen in west central of Sweden. Sälen is a village located near the Norwegian border, although fairly sparsely populated. The destination has annually about one million official guest nights, based on the 414 000 visitors who stay an average of about 4, 5 days.  Per visit, these tourists individually spend an average of 862 SEK on shopping at the destination. The expenditure of the mountain tourists together with the Norwegian border shoppers makes it very interesting to explore the opportunities for shopping development in terms of a shopping centre in the region of Sälen.

The facial affective scale as a predictor for pain unpleasantness when children undergo immunizations.

Needle fear is a common problem in children undergoing immunization. To ensure that the individual child's needs are met during a painful procedure it would be beneficial to be able to predict whether there is a need for extra support. The self-reporting instrument facial affective scale (FAS) could have potential for this purpose. The aim of this study was to evaluate whether the FAS can predict pain unpleasantness in girls undergoing immunization. Girls, aged 11-12 years, reported their expected pain unpleasantness on the FAS at least two weeks before and then experienced pain unpleasantness immediately before each vaccination. The experienced pain unpleasantness during the vaccination was also reported immediately after each immunization. The level of anxiety was similarly assessed during each vaccination and supplemented with stress measures in relation to the procedure in order to assess and evaluate concurrent validity. The results show that the FAS is valid to predict pain unpleasantness in 11-12-year-old girls who undergo immunizations and that it has the potential to be a feasible instrument to identify children who are in need of extra support to cope with immunization. In conclusion, the FAS measurement can facilitate caring interventions.

Beyond the Threshold: Life in the New Russia

Amanda Sprang spent nine months, from September of 1995 to May of 1996, studying at Colby College's program in St. Petersburg, Russia. Through contacts made during previous trips to Russia in middle and high school, Amanda was able to quickly rekindle her old friendships and make new ones with many young Russians from different backgrounds. The following work is a collection of twelve essays about life in the New Russia. The essays are framed by a foreword and an epilogue that help place the entire work in a historical context. Although the theme of each essay emerges from a particular incident, within every story Amanda has addressed numerous topics relating to Russian life in today’s changing society. Her first essay, “Art Klinika," takes place in an avant-garde night club in St. Petersburg, and includes a brief yet impressionable, encounter with three young Russian men. “The Birthday Party” recalls a wild evening at the home of her close friend, showing how the Russians greet special occasions. Both the third and fourth essays take place in Moscow, where Amanda returns to visit old friends. These two essays portray the lives of the new economic elite in comparison with the average citizen, as well as show how young Russians face the new challenges that greet them. "Politics Russian Style" recalls a political rally in St. Petersburg, and attempts to shed light on the wacky political world of an infant democracy. Chapters Six through Ten take place away from the western cities of St. Petersburg and Moscow, as Amanda brings us to the cold, mysterious land of Siberia in the dead of winter. She recounts her five day train ride with a retired, high-powered, Communist party official, her experiences in the provincial city of Irkutsk, and a brief trip to a Buddhist monastery and, later, an excursion to Lake Baikal. Back in St. Petersburg, Chapter Eleven gives a humorous account of a ski trip with several Russian friends. Amanda finishes her work with her final chapter, “The Dacha," which describes a weekend spent at a Russian country home with her friend's family.

Participação Infantil: experiência de pesquisa realizada em organização social na Zona Oeste do Rio de Janeiro

Este trabalho se propõe a ser um fio na teia de reflexões que tecem o debate sobre a participação infantil a partir do ponto de vista das crianças em co-operação com adultos. Sua trama se compõe de campos distintos e autônomos - infância, direito social e participação -, que se cruzam e inter-relacionam, investigados no âmbito de uma experiência realizada na organização social Fundação Xuxa Meneghel, que tem como eixo central de suas ações a promoção e a proteção de crianças e adolescentes que vivem em situação de vulnerabilidade social na Zona Oeste do município do Rio de Janeiro. Trata-se de uma micro-experiência, que pretende compreender o ser criança em relação aos seus direitos humanos e sociais, observando sua influência nas práticas sociais presentes na nossa cultura. O direito à participação infantil - entendida como ferramenta para a auto-proteção e a promoção das crianças como sujeitos plenos exercitando a cidadania - se materializou numa investigação em que as concepções metodológicas convencionais foram se re-construindo por meio das vozes infantis em diálogo com seus pares e com os adultos. As crianças apresentaram seus pontos de vista e as significações que atribuem ao seu entorno e a suas possibilidades e limites de participar de forma genuína nas suas principais instâncias de socialização: família, escola e comunidade. A experiência se constitui numa provocação do olhar para as identidades e as culturas das crianças que dela participaram, para suas vivências expressas por representações de ações e emoções contextualizadas no tempo e no espaço, numa tentativa de compor com elas - e ampliando para todas as crianças da instituição - uma compreensão do que significa o direito de participar, ensinado e apreendido em perspectiva social e cultural.

Um estudo sobre a estratégia de expansão de uma escola bilíngüe

The present Study of Case has an objective to describe the development of the Project for the opening of a new unit of a bilingual educational organization in the west zone of Rio de Janeiro. The study of case shows the reasons for the growth of the bilingual educational institutions, growth of the west zone and the decision of the opening of a new unit of the School in question in this specific area. The School in study solicited for its identity to be maintained undisclosed. It opted for the realization of a study of case to describe the development of the project, in a systemized way, through a bibliography and documental research. The limitation of this case is based on the fact of being a single study case. This project can be generalized for other projects within the same institution or replicated to other educational institutions, even if it¿s not bilingual.

O professor como aluno

Esta dissertação relata a experiência de avaliação do grau de conhecimento adquirido pelo professor durante o seu processo de formação em relação à Proposta Curricular do 1o grau do Município do Rio de Janeiro, a qual pretende ver o construtivismo vivenciado em sala de aula, no processo ensino-aprendizagem. Esta experiência foi realizada durante o trabalho de supervisão educacional num Distrito de Educação e Cultura - DEC, da Zona Oeste do Rio. Para tanto, analisamos aspectos sócio-econômico, político, cultural e educacional da referida região, onde trabalhamos há mais de 25 anos. Evidenciamos com este estudo uma face da nossa realidade escolar, a proposta curricular. Nosso trabalho recebeu influências tanto de um dos projetos do Centro de Ciências do Estado do Rio de Janeiro - Cecierj, como de sua aplicação em nosso trabalho de supervisorajunto aos professores e às escolas públicas. A partir dessa prática, é sugerida uma linha de ação viável para a disseminação do construtivismo nas salas de aula, com ênfase na vivência, pelo professor, daquilo que ele proporcionará ao aluno.

O computador na escola: um exame de uma prática

Este estudo objetivou contribuir para um melhor entendimento do processo de informatização em nossas escolas, enfatizando uma vertente ainda pouco explorada pelos pesquisadores: as possíveis mudanças organizacionais decorrentes da utilização do microcomputador. Esta temática foi introduzida, nesta dissertação, a partir da contextualização de algumas das inúmeras dimensões pedagógicas, históricas, econômicas, políticas e sociais, que entremeadas, formam o intrincado tecido da informatização da educação. Para seu desenvolvimento, tornou-se necessário adaptar-se a proposta de Robert Shirley (1976) para o exame de mudanças organizacionais e utilizou-se de algumas categorias de análise sugeridas por Sheingold e outras (1983). Realizou-se uma pesquisa, em estabelecimento educacional localizado na zona oeste da cidade do Rio de Janeiro, que pode ser classificada como um estudo de caso de caráter exploratório. Nesta pesquisa foram empregadas a observação não participante, entrevistas padronizadas e não padronizadas, questionários e análise documental. Em relação às estratégias de mudança, não se constatou o aparecimento dos novos papéis, a preparação formal dos professores não atingiu a maior parte do corpo docente e o acesso aos microcomputadores, restrito aos alunos do primeiro segmento do 12 grau, viu-se bastante limitado. Os sistemas de coordenação revelaram-se bastante centralizados e a distribuição de pOder mostrou-se hierarquizada, com forte submissão à autoridade da família proprietária. Diante de tal quadro, a participação dos professores, apesar de solicitada pela coordenação de informática, era na verdade imposta pela direção. O software adotado pela instituição foi o LOGO, utilizado ao lado da análise do discurso da criança. A síntese dos resultados evidenciou o crescente processo de mercantilização do ensino em nosso país e do uso da informática como um novo atrativo para a matrícula de novos alunos. Como conseqOência disto, surge a necessidade de novos estudos para se confirmar a relevância pedagógica da informatização do ensino ou para constatar-se, em escolas preocupadas apenas com o faturamento, sua importância comercial.

Who is the cowboy in Washington?: beating google at their own game with neuroscience and cryptography

Who was the cowboy in Washington? What is the land of sushi? Most people would have answers to these questions readily available,yet, modern search engines, arguably the epitome of technology in finding answers to most questions, are completely unable to do so. It seems that people capture few information items to rapidly converge to a seemingly 'obvious' solution. We will study approaches for this problem, with two additional hard demands that constrain the space of possible theories: the sought model must be both psychologically and neuroscienti cally plausible. Building on top of the mathematical model of memory called Sparse Distributed Memory, we will see how some well-known methods in cryptography can point toward a promising, comprehensive, solution that preserves four crucial properties of human psychology.

Negros misturados: um estudo de caso sobre identidades negras em Mossoró-RN

With more or less 213.000 habitants, Mossoró is the second more developed city from the Rio Grande do Norte. The town is proclamated like the land of freedom. To so far, exist four moments in your history related with the defence of freedom that is point like truthful from so proclamation. Suchlike happenings are the first female vote on Brazil, the resistance against the Lampião s band, the worman s mutiny and the slave release in 1883, five year before the Áurea law sanction. These happenings are commemorate yearly on setember with one big theatrical event called by the freedom high. Inside this contexto of exaltation to freedom, there is one black movement by name black and beautiful. Is the present dissertation, talked about the building of black identities between the black militants of Mossoró and the dwellers from the Santo Antônio district. With such approach, we intend to think about possibles differences or likeness, how the militants and dwellers from the refered district self-calleds like blacks or not. We are understanding black identity like one process to self-affirmation done by specificities of the social context and the individual particularity. This way, the identity change into one dynamic and contextual reality, gone always by one business process against the interaction of the social actors. So we search to discuss the specificities that involve the process to building of black identities in the city of freedom

Encalhes de Cetáceos ocorridos no período de 1984 a 2005 no litoral do Rio Grande do Norte, Brasil

Strandings of live or dead aquatic mammals constitute an important instrument to provide information regarding the occurrence, biology and ecology of these species. The aim of this study was to register the stranded species of cetaceans, the frequency and the spatial-temporal distribution of theses strandings during the period of 1984 to 2005, in the coast of Rio Grande do Norte. Data was acquired through the monitoring of strandings in the north, north-west and south coast of RN, and through information obtained from institutions and newspaper archives of the State. A total of 122 strandings of cetaceans were registered along the coast of Rio Grande do Norte. Of the 14 species of cetaceans registered, four species had higher frequencies: Sotalia guianensis (n= 65), Steno bredanensis (n = 6), Globicephala macrorhynchus (n = 6) and Physeter macrocephalus (n = 7). Out of 118 strandings, 93 occurred in the south coast (78.8 %), 23 in the north coast (19.5%) and 2 (1.7%) in the north-west coast of the State. The highest frequency of strandings occurred during the months of August to March and the maximum number of strandings occurred from 2000 onwards, as a consequence of the intense monitoring of the Pequenos Cetáceos Project in Rio Grande do Norte

Contribuição da catodoluminescência para o entendimento da diagênese da formação Jandaíra: áreas do campo de petróleo da fazenda Belém e Lajedo do Rosário

The general objective of this study was to contribute to the understanding of the chemical evolution of fluids that percolate through carbonate rocks of the Jandaíra Formation. The oxidation and reduction conditions in which grains, source and cement were formed was investigated using the cathodoluminescence technique (CL). The study area is located in the west part of the Potiguar Basin (Fazenda Belém field) and Rosário Ledge (Felipe Guerra municipality, State of Rio Grande do Norte, Brazil). The analysis of thin sections of carbonate rocks under CL revealed that grains (allochemical or not) and diagenetic products (micritization, dolomitization, neomorphism and cementation) exhibit since absence of luminescence the various luminescence colors (yellow, orange, red, brown, and blue) in a variety of intensities. As pure calcite shows dark blue luminescence, the occurrence of different luminescence colors in calcite crystals suggest one or more punctual crystal defects such as free electron, free space and impurity. The dyeing of thin sections with alizarin and potassium ferrocyanide revealed the absence of ferrous carbonate in the different lithotypes of Jandaíra Formation. Therefore, the different colors and intensities of CL observed in these rocks are probably caused by the presence of ion activators such as Mn2+ and is not an activator/inhibitor combination. In the same way, the absence of luminescence is very probably caused by the absence of activator ions and not due to the low concentration of inhibitor ions such as Fe2+. The incorporation of Mn2+ in the different members of the Jandaíra Formation must have been controlled by the redox state of the depositional environment and diagenesis. Therefore, it is possible that the luminescent members have been formed (e.g.,ooids) or have been modified (gastropod neomorphism) under reduction conditions in the depositional environments, in subsurface during the burial, or, in the case of Rosario Ledge samples , during the post-burial return to surface conditions. As regards the sudden changes from low to moderate and to strong luminescence, these features should indicate the precipitation of a fluid with chemical fluctuations, which formed the frequent zonations in the block cement of the Rosario Ledge samples. This study suggests that the different intensities and colors of CL should be correlated with the Mn2+ and Fe2+ contents, and stable isotopes of samples to determine the salinity, temperature, pH e Eh conditions during deposition
