Delayed traveling ionospheric disturbances, especially in equatorial regions, following geomagnetic activity

For the Western-Pacific region spread-F has been found to occur with delays after geomagnetic activity (GA) ranging from 5 to 10 days as station groups are considered from low midlatitudes to equatorial regions. The statistical (superposed-epoch) analyses also indicate that at the equator the spread-F, and therefore associated medium-scale traveling ionospheric disturbances (MS-TIDs) occur with additional delays around 16, 22 and 28 days representing a 6-day modulation of the delay period. These results are compared with similar delays, including the modulation, for D-region enhanced hydroxyl emission (Shefov, 1969). It is proposed that this similarity may be explained by MS-TIDs influencing both the F and D regions as they travel. Long delays of over 20 days are also found near the equator for airglow-measured MS-TIDs (Sobral et al., 1997). These are recorded infrequently and have equatorward motions, while normally eastward motions are measured at the equator. Also in midlatitudes D-region absorption events have been shown (statistically) to have similar long delays after GA. It is suggested that atmospheric gravity waves and associated MS-TIDs may be generated by some of the precipitations responsible for the absorption. The recording of the delayed spread-F events depends on the GA being well below the average levels around sunset on the nights of recording. This implies that lower upper-atmosphere neutral particle densities are necessary.

Biogeographic analysis of jurassic-early cretaceous wood assemblages from Gondwana

The terrestrial biogeography of Gondwana during Jurassic-Early Cretaceous times is poorly resolved, and the flora is usually considered to have been rather uniform. This is surprising given the size of Gondwana, which extended from the equator to the South Pole. Documenting Gondwanan terrestrial floristic provincialism in the Jurassic-Early Cretaceous times is important because it provides a historical biogeographic context in which to understand the tremendous evolutionary radiations that occurred during the mid-Cretaceous. In this paper, the distribution of Jurassic-Early Cretaceous fossil wood is analysed at generic level across the entire supercontinent. Specifically, wood assemblages are analyzed in terms of five climatic zones (summer wet, desert, winter wet, warm temperate, cool temperate) established on the basis of independent data. Results demonstrate that araucarian-like conifer wood was a dominant, cosmopolitan element, whereas other taxa showed a greater degree of provincialism. Indeed, several narrowly endemic morphogenera are recognizable from the data. Finally, comparisons with Laurasian wood assemblages indicate strong parallelism between the vegetation of both hemispheres. (C) 2004 Elsevier B.V. All rights reserved.

Adaptive responses of wild mungbean (Vigna radiata ssp sublobata) to photo-thermal environment. I. Phenology

The phenology of 11 diverse accessions of wild mungbean was observed under natural and artificial photoperiod - temperature conditions, in order to examine whether genotypic differences might be attributed to adaptive responses to photo-thermal conditions. There was large variation in phenological response among accessions and across environments, much of which was due to differences in the duration of the pre-flowering phase. Accessions that flowered earlier tended to flower for longer, apart from 2 earlier flowering, inland Australian lines that were also earlier maturing. The patterns of response in time from sowing to flowering over environment were consistent with quantitative short-day photoperiodic adaptation, a conclusion supported by the effects of artificial day-length extension and by 'goodness of fit' of the observed responses to standard models relating rate of development to photoperiod and temperature. The fitted models indicated that rate of development towards flowering was hastened by warmer temperatures, and delayed by longer day lengths, with differential sensitivity between accessions to both factors. The models also suggested that photoperiod was more important for accessions collected closer to the equator, which were generally later flowering as a consequence. Conversely, temperature was relatively more important in lines from higher latitudes. Modelling also suggested that the period from first flowering to maturity was sensitive to photoperiod and temperature. Again, longer days appeared to prolong growth and delay maturity. However, cooler temperatures accelerated rather than slowed maturity, by suppressing further vegetative growth. The variation observed indicated that there is considerable scope for using the wild population to broaden the adaptation of cultivated mungbean. In particular, the unusual response of a late-flowering, photoperiod-insensitive accession warrants further study to establish whether the wild population contains a unique 'long juvenile' trait analogous to that being used for improving phenological adaptation in soybean.

Population differences in finger-length ratios: Ethnicity or latitude?

The relative length of the second and fourth fingers (the 2D:4D ratio) has been taken to be an indicator of prenatal exposure to testosterone, and hence possibly relevant to sexual orientation and other sex-differentiated behaviors. Studies have reported a difference in this ratio between Caucasian males in Britain and in the U.S.: higher average 2D:4D ratios were obtained in Britain. This raises the question of whether differences among different Caucasian gene pools were responsible or whether some environmental variable associated with latitude might be involved (e.g., exposure to sunlight or different day-length patterns). This question was explored by examining 2D:4D ratios for an Australian adolescent sample. The Australians were predominantly of British ancestry, but lived at distances from the equator more like those of the U.S. studies. The Australian 2D:4D ratios resembled those in Britain rather than those in the U.S., tending to exclude hypotheses related to latitude and making differences in gene pools a plausible explanation.

A total electron content space weather study of the Nighttime Weddell Sea Anomaly of 1996/97 southern summer with TOPEX/Poseidon radar altimetry

This paper reports on a total electron content space weather study of the nighttime Weddell Sea Anomaly, overlooked by previously published TOPEX/Poseidon climate studies, and of the nighttime ionosphere during the 1996/1997 southern summer. To ascertain the morphology of spatial TEC distribution over the oceans in terms of hourly, geomagnetic, longitudinal and summer-winter variations, the TOPEX TEC, magnetic, and published neutral wind velocity data are utilized. To understand the underlying physical processes, the TEC results are combined with inclination and declination data plus global magnetic field-line maps. To investigate spatial and temporal TEC variations, geographic/magnetic latitudes and local times are computed. As results show, the nighttime Weddell Sea Anomaly is a large (∼1,600(°)2; ∼22 million km2 estimated for a steady ionosphere) space weather feature. Extending between 200°E and 300°E (geographic), it is an ionization enhancement peaking at 50°S–60°S/250°E–270°E and continuing beyond 66°S. It develops where the spacing between the magnetic field lines is wide/medium, easterly declination is large-medium (20°–50°), and inclination is optimum (∼55°S). Its development and hourly variations are closely correlated with wind speed variations. There is a noticeable (∼43%) reduction in its average area during the high magnetic activity period investigated. Southern summer nighttime TECs follow closely the variations of declination and field-line configuration and therefore introduce a longitudinal division of four (Indian, western/eastern Pacific, Atlantic). Northern winter nighttime TECs measured over a limited area are rather uniform longitudinally because of the small declination variation. TOPEX maps depict the expected strong asymmetry in TEC distribution about the magnetic dip equator.

O CONCÍLIO DOS DEUSES NO SALMO 82 E NA LITERATURA UGARÍTICA

O salmo 82, desde o início de seus versos, mostra o ambiente no qual se situa seu cântico: o concílio dos deuses. Nessa reunião celestial, um deus se levanta e acusa os outros deuses de negligenciar os mais fracos. Os deuses são condenados à morte e o deus que preside a assembleia dos deuses nomeia outro deus para governar todas as nações da terra. A cena do concílio dos deuses e os decretos promulgados nesses encontros no mundo celestial são recorrentes em outras literaturas do Antigo Oriente Próximo. Na literatura religiosa de Ugarit, antiga cidade cananeia, El, Baal, Asherah e outras deidades se reúnem para discutir assuntos pertinentes à ordem do cosmos. Nesse sentido, o Salmo 82 compartilha elementos da religiosidade e da cultura dos cananeus.

QUANDO OS ESPÍRITOS SAEM DO ABISMO: O ESTABELECIMENTO NARRATIVO DO TERROR ESCATOLÓGICO EM APOCALIPSE 9,1-21

O Apocalipse de João é uma obra instigante. Sua linguagem cheia de violência, com monstros aterrorizantes, pessoas clamando por justiça, anúncios de mortes e desespero, em um quadro de espetáculos celestes, fascina os que gostam de ficção e alimenta a esperança dos que esperam um dia entrar na Nova Jerusalém, onde não haverá mar nem morte, quando as lágrimas serão enxugadas. Contudo, o livro do Apocalipse será lido como uma narração da realidade. Nesse sentido, o texto não é visto como reflexo de qualquer opressão, mas construção discursiva a respeito do sistema que, para o visionário, é a negação da ordem. Neste trabalho, a partir dos conceitos de texto e memória cultural, à luz das pesquisas de I. Lótman, da escola russa de semiótica da cultura e das pesquisas dos Assmann, observar-se-á como as memórias de seres celestes caídos e aprisionados da tradição enoquita estão presentes na literatura judaico-cristã e servem para a construção narrativa do cenário de terror escatológico na quinta e sexta trombetas de Ap 9,1-21. Assim sendo, a tese defende o terror como instrumento de persuasão, o qual serviu, na estratégia do visionário, para descrever o seu contexto como realidade caótica. Por meio de estratégias narrativas, o narrador deseja que sua visão seja levada a sério e que seus interlocutores aceitem a sua interpretação da realidade, deixando a associação com a vida e sistema romanos, pois se assim procederem serão comparados aos selados e receberão as mesmas recompensas. Dessa maneira, sua descrição com linguagem escatológica joga com o futuro e com o presente; prevê o caos, mas o vive em nível narrativo. Por isso o livro do Apocalipse, com um dualismo extremamente radical, não dá espaços para dúvidas. A tese defende, portanto, que essa obra pode ser lida como instrumento retórico de terror e medo que leva seus leitores implícitos a não flertarem com Roma, a não aceitarem seus discursos ou os que com ela se associam.

TRANSFORMAÇÃO MÍSTICA NA RELIGIÃO DO APÓSTOLO PAULO A recepção do Moisés glorificado em 2º Coríntios na perspectiva da experiência religiosa

Esta tese é um estudo do conceito de transformação místico-apocalíptica na perspectiva da experiência religiosa e que tem como objeto o caso paulino. As pesquisas sobre Paulo Apóstolo geralmente acompanham a abordagem tradicional que o vê como pensador e teólogo. Mas, em sintonia com algumas obras do passado e especialmente as mais recentes sobre Paulo em relação à apocalíptica e misticismo judaicos, esta tese desenvolve uma análise na perspectiva da experiência religiosa. Considerando a tradição de ascensão visionária como quadro de plausibilidade, é apresentada uma análise dos relatos de ascensão da literatura judaica antiga, com destaque para Moisés, aqui comparado com a recepção paulina do Moisés transformado em 2º Coríntios. O resultado da pesquisa foi que a literatura judaica antiga testemunha um padrão de transformação proléptica em ascensão celestial que fazia parte das crenças e práticas religiosas. A linguagem usada por Paulo em 2º Coríntios, notoriamente no capítulo 3, demonstra que ele estava envolvido em tais crenças e práticas, ainda que com conotações próprias. O Moisés transformado de face gloriosa de Êxodo 34, que foi recebido pelas tradições judaicas como um viajante celestial, o que era corrente nos tempos paulinos, é o foco de Paulo em 2º Coríntios 3. Para Paulo, sua condição é superior à de Moisés porque ele tem acesso livre e permane nte à gloria de Deus, acesso esse estendido a seus correligionários e que resulta em processo de transformação proléptica. Também porque seu evangelho é uma revelação cristológica divina última superior ao que foi revelado a Moisés no Sinai. Este acesso livre e permanente que inclui esta transformação antecipada se dá em termos de cultos extáticos de natureza visionária.(AU)

O CAMINHO DO CORDEIRO: REPRESENTAÇÃO E CONSTRUÇÃO DE IDENTIDADE EM APOCALIPSE 14.1-5

Ao analisar Apocalipse 14.1-5, esta pesquisa encontrou afirmações que parecem representar a identidade de João e sua audiência, bem como a forma como eles concebiam o mundo. Nos seus elementos litúrgicos, estas pessoas se viam como sacerdotes de Deus, membros do seu reino, participantes do seu culto celestial e com dignidade exa ltada como a dos anjos do céu. Alguns elementos identitários, entretanto, não são compartilhados plenamente entre João e suas comunidades. O autor de Apocalipse possui altas demandas ascéticas e sectárias que o afastam não apenas da sociedade mais ampla, mas de qualquer irmão que tenha uma posição divergente. Ele enxerga o mundo mergulhado num conflito entre o Dragão e o Cordeiro, conflito esse que será vencido com a participação de 144.000 guerreiros através da prática do martírio. Esta tradição da guerra santa insere no Apocalipse o potencial de isolar sectariamente a audiência da sociedade e de outros grupos religiosos.(AU)

Theoretical studies of the mid-latitude ionosphere

Following a brief description of the atmosphere and ionosphere in Chapter I we describe how the equations of continuity and momentum for 0+, H+, He+, 0++ are derived from the formulations of St-Maurice and Schunk(1977) and Quegan et al.(1981) in Chapter II. In Chapter III we investigate the nature of the downward flow of protons in a collapsing post-sunset ionosphere. We derive an analytical form for the limiting temperature, we also note the importance of the polarization field term and concluded that the flow will remain subsonic for realistic conditions. The time-dependent behaviour of He+ under sunspot minimum conditions is investigated in Chapter IV. This is achieved by numerical solution of the 0+, H+ and,He+ continuity and momentum equations, treating He+ as a minor ion with 0+ , H+ as major ions. We found that He+ flows upwards during the day-time and downwards during the nighttime. He+ flux tube content reached a maximum on the 8th day of the integration period and started to decreasing. This is due to the large amount of H+ present at the late stages of the integration period which makes He+ unable to diffuse through the H+ layer away from the loss region. In Chapter V we investigate the behaviour of 0++ using sunspot maximum parameters. Although our results support the findings of Geis and Young (1981) that the large amounts of 0++ at the equator are caused mainly by thermal diffusion, the model used by Geis and Young overemphesizes the effect of thermal diffusion. The importance of 0++ - 0+ collision frequency is also noted. In Chapter VI we extend the work of Chapter IV, presenting a comparative study of H and He at sunspot minimum and sunspot maximum.In this last Chapter all three ions, O+ ,H+ and He+ , are treated theoretically as major ions and we concentrate mainly on light ion contents and fluxes. The results of this Chapter indicate that by assuming He+ as a minor ion we under-estimate He+ and over-estimate. H+. Some interesting features concerning the day to day behaviour of the light ion fluxes arise. In particular the day-time H+ fluxes decrease from day to day in contrast to the work of Murphy et al.(1976). In appendix.A we derive some analytical forms for the optical depth so that the models can include a realistic description of photoionization.

Relationship between sunlight and the age of onset of bipolar disorder:an international multisite study

Background - The onset of bipolar disorder is influenced by the interaction of genetic and environmental factors. We previously found that a large increase in sunlight in springtime was associated with a lower age of onset. This study extends this analysis with more collection sites at diverse locations, and includes family history and polarity of first episode. Methods - Data from 4037 patients with bipolar I disorder were collected at 36 collection sites in 23 countries at latitudes spanning 3.2 north (N) to 63.4 N and 38.2 south (S) of the equator. The age of onset of the first episode, onset location, family history of mood disorders, and polarity of first episode were obtained retrospectively, from patient records and/or direct interview. Solar insolation data were obtained for the onset locations. Results - There was a large, significant inverse relationship between maximum monthly increase in solar insolation and age of onset, controlling for the country median age and the birth cohort. The effect was reduced by half if there was no family history. The maximum monthly increase in solar insolation occurred in springtime. The effect was one-third smaller for initial episodes of mania than depression. The largest maximum monthly increase in solar insolation occurred in northern latitudes such as Oslo, Norway, and warm and dry areas such as Los Angeles, California. Limitations - Recall bias for onset and family history data. Conclusions - A large springtime increase in sunlight may have an important influence on the onset of bipolar disorder, especially in those with a family history of mood disorders.
