Mártires e martírios num mundo em expansão : S. Tomé no Império Português entre a Índia e o Brasil

Este artigo tem como objecto de análise o culto do Apóstolo São Tomé no Império Português desde a Índia ao Brasil. A expansão deste culto, bem como as suas origens nos tempos apostólicos são directamente relatados e patenteados na cronologia portuguesa da expansão. Além disso, a devoção a São Tomé, Apóstolo e Mártir, desempenhará um papel importante no plano político, que, por sua vez, contribuirá para o fomento desteculto apostólico. O interesse político neste culto terá implicações no plano devocional,social e na expressão artística (peregrinações, relíquias, heranças). No nosso ponto de vista, o carácter sincrético que esta figura de mártir e santo assume no quadro do Império Português será destacado e analisado com uma ênfase especial.

Bezpieczeństwo energetyczne i ekologiczne na przykładzie węgla brunatnego w Polsce

The analysis in the text involves selected aspects of brown coal sector functioning in Poland. The analysis has been made in the context of Poland’s energy security and ecological safety, which seems important due to the need to implement low-emission energy policy. In relation to the sole fact that electricity production relies on coal, Poland will face the need to undertake major sector transformations in the coming 20-30 years. Two main parts of the text focus on the problem of energy security and ecological safety. In the earlier case, brief characteristic of the coal energy sector in Poland has been presented, namely the potential of brown coal, selected economic problems related to functioning of the sector, and orientation of Polish energy policy in this respect. In turn, the problem of ecological safety has been brought down to the impact of mines on the natural environment. Hence, the paper presents selected problems of threats to the natural and anthropogenic environment, as well as threats related to particular phases of energy production from brown coal. Furthermore, the text considers possible measures in the area of reclamation of areas where brown coal sector has been located. *** Przedmiotem analizy w tekście są wybrane aspekty funkcjonowania sektora węgla brunatnego w Polsce. Analiza ta została podjęta w kontekście bezpieczeństwa energetycznego i ekologicznego Polski, co wydaje się istotne, ze względu na konieczność wdrażania niskoemisyjnej polityki energetycznej. W związku z faktem oparcia produkcji energii elektrycznej na węglu w ogóle, Polskę czeka konieczność podjęcia poważnych przekształceń sektorowych w ciągu najbliższych 20-30 lat. Dwie główne części tekstu oparto na problematyce bezpieczeństwa energetycznego i bezpieczeństwa ekologicznego. W pierwszym przypadku przedstawiono krótką charakterystykę węglowego sektora energetycznego w Polsce, tj. potencjał węgla brunatnego, wybrane problemy gospodarcze związane z funkcjonowaniem tego sektora oraz kierunki polskiej polityki energetycznej w tym zakresie. Natomiast problem bezpieczeństwa ekologicznego został sprowadzony do wpływu kopalń na środowisko naturalne. Stąd w pracy przedstawiono wybraną problematykę zagrożeń dla środowiska naturalnego i antropogenicznego, także zagrożenia związane z poszczególnymi etapami produkcji energii pochodzącej z węgla brunatnego. Ponadto, w tekście uwzględniono potencjalne działania w zakresie rekultywacji obszarów, na których został zlokalizowany sektor węgla brunatnego.

Orde Wingate, the Iron Wall and Counter-terrorism in Palestine, 1936-1939

A pamphlet published by the British Army's Strategic and Combat Studies Institute on the then Captain Orde Wingate's formation and command of the Anglo-Jewish Special Night Squads in the Palestine Arab revolt of 1936-1939, with a discussion of their long-term strategic and political implications.

Cusp observations during a sequence of fast IMF B-Z reversals

In recent years, a large number of papers have reported the response of the cusp to solar wind variations under conditions of northward or southward Interplanetary Magnetic Field (IMF) Z-component (BZ). These studies have shown the importance of both temporal and spatial factors in determining the extent and morphology of the cusp and the changes in its location, connected to variations in the reconnection geometry. Here we present a comparative study of the cusp, focusing on an interval characterised by a series of rapid reversals in the BZ-dominated IMF, based on observations from space-borne and ground-based instrumentation. During this interval, from 08:00 to 12:00 UT on 12 February 2003, the IMF BZ component underwent four reversals, remaining for around 30 min in each orientation. The Cluster spacecraft were, at the time, on an outbound trajectory through the Northern Hemisphere magnetosphere, whilst the mainland VHF and Svalbard (ESR) radars of the EISCAT facility were operating in support of the Cluster mission. Both Cluster and the EISCAT were, on occasion during the interval, observing the cusp region. The series of IMF reversal resulted in a sequence of poleward and equatorward motions of the cusp; consequently Cluster crossed the high altitude cusp twice before finally exiting the dayside magnetopause, both times under conditions of northward IMF BZ. The first magnetospheric cusp encounter, by all four Cluster spacecraft, showed reverse ion dispersion typical of lobe reconnection; subsequently, Cluster spacecraft 1 and 3 (only) crossed the cusp for a second time. We suggest that, during this second cusp crossing, these two spacecraft were likely to have been on newly closed field lines, which were first reconnected (opened) at low latitudes and later reconnected again (re-closed) poleward of the northern cusp.

Experimental comparison of the comprehensibility of a Z specification and its implementation in Java

Comprehensibility is often raised as a problem with formal notations, yet formal methods practitioners dispute this. In a survey, one interviewee said 'formal specifications are no more difficult to understand than code'. Measurement of comprehension is necessarily comparative and a useful comparison for a specification is against its implementation. Practitioners have an intuitive feel for the comprehension of code. A quantified comparison will transfer this feeling to formal specifications. We performed an experiment to compare the comprehension of a Z specification with that of its implementation in Java. The results indicate there is little difference in comprehensibility between the two. (C) 2004 Elsevier B.V. All rights reserved.
