Stephen Martin Leake: a Victorian's view of the Common Law

This article considers the life and work of Stephen Martin Leake and seeks to locate his work within the wider context of the procedural and substantive transformation of the mid-to-late Victorian legal world. In particular, the article attempts to rescue Leake from obscurity and emphasise his importance in this process. It is argued that Leake’s work began the process whereby common lawyers conceived of their law as organised in a principled rather than procedural manner. Later common law jurists built upon this work. Consideration is also given to the philosophical and jurisprudential sources upon which Leake drew in constructing his treatises.

Railway promotion in Victorian Britain: engineering triumph or waste of capital?

A key issue in UK railway history is whether the railway system was an efficient response to the traffic requirements of the economy. The UK railway system was constructed entirely by private enterprise with minimal state subsidies. This chapter considers whether the railway system was 'over-built' because the government ignored the advice of the Railway Committee of the Board of Trade. The chapter suggests that the system was over-built by about 35 per cent. The causes of this over-building are investigated and are found to be mainly social and political failures arising from distrust between MPs and civil servants and public pressure on local MPs to ensure that their constituencies were well served by railways.

Dereplication of Bromotyrosine-derived Metabolites by LC-PDA-MS and Analysis of the Chemical Profile of 14 Aplysina Sponge Specimens from the Brazilian Coastline

In order to investigate the chemical profile of 14 specimens of Aplysina spp. marine sponges, we have developed a method based on LC-PDA-MS for the detection of bromotyrosine-derived metabolites. The method enabled the dereplication of three distinct chemotypes of bromotyrosine-derived compounds based on UV absorptions, which were further refined by electrospray ionization-mass spectrometry analysis of the brominated quasi-molecular ion clusters. This procedure led to either a single compound assignment, or a maximum of two possible isobaric compounds. The dereplication study indicated that the chemical profile of the 14 specimens of Aplysina spp. analyzed presented practically the same dibromotyrosine-derived compounds. The results obtained suggested a possible biogenetic pathway for the formation of dibromotyrosine-derived compounds of wide occurrence in Verongida sponges.

Effect of coastline properties and wastewater on plankton composition and distribution in a stressed environment on the north coast of Olinda-PE (Brazil)

Foi realizado um estudo sobre a estrutura das comunidades planctônicas ao longo das praias de Casa Caiada e Rio Doce (Pernanbuco, Brasil). A área de estudo sofre grande influência antrópica onde as condições ambientais são controladas pela presença de estruturas costeiras, reduzindo a intensidade da circulação neste ambiente; e pelos efluentes clandestinos de esgoto que aportam águas poluídas para dentro do sistema protegido. Os resultados obtidos indicam que nas zonas protegidas as águas apresentam alta turbidez, temperaturas elevadas, salinidades reduzidas e altas concentrações de nutrientes e oxigênio. Estas condições são responsáveis pela redução da diversidade do plâncton e pelo aumento da biomassa das espécies mais resistentes. As diferenças registradas com respeito a áreas similares, porém não impactadas, parecem indicar que a estrutura planctônica pode ser usada como um indicador da qualidade ambiental, sugerindo uma baixa qualidade das praias em estudo.

Hamlet's Ophelia: The Changing Perceptions of Suicide, Death, and Madness in the Elizabethan and Victorian Periods

William Shakespeare's Hamlet, Prince of Denmark has been the source of question, debate, and research since its theatrical debut. In the midst of readings performances and one particular question has remained open and unresolved: was Ophelia's death an accident or a suicide? Some see Ophelia's death as an accident; others see it as a suicide resulting from the accumulation of a series of unfortunate events: her rejection by her boyfriend, her father’s murder, and her possible pregnancy. This paper will explore that age-old question from the perspectives of two historically different audiences: those of sixteenth-century and nineteenth-century England. I will argue that, despite the 300-year expanse between these two audiences, both emerged with the same conclusion: Ophelia's death was accidental. However, cultural and scientific changes affected the reasons why each came to that conclusion.

SECONDARY METABOLITES FROM NUDIBRANCHS Tambja stegosauriformis, Hypselodoris lajenis AND Okenia zoobotryon AND FROM BRYOZOANS Zoobotryon verticillatum AND Bugula dentata FROM THE BRAZILIAN COASTLINE

SECONDARY METABOLITES FROM NUDIBRANCHS Tambja stegosauriformis, Hypselodoris lajenis AND Okenia zoobotryon AND FROM BRYOZOANS Zoobotryon verticillatum AND Bugula dentata FROM THE BRAZILIAN COASTLINE. The chemical investigation of the MeOH extract from the bryozoan B. dentata MeOH yielded tambjamines A (1), C (3), D (4), K (6), aldehyde 8 and the new tambjamine J1(9), while the extract of its predator, the nudibranch Tambja stegosauriformis, yielded tambjamines C and K, along with aldehyde 8. Furodisinin lactone (11) was isolated from the nudibranch Hypselodoris lajensis, a compound previously isolated from Dysidea sponges. The alkaloid 2,5,6-tribromo-N-methylgramine (12) was isolated from the nudibranch Okenia zoobotryon and from its prey, the bryozoan Zoobotryon verticillatum, the only source of 12 previously known.

Coastline changes and sedimentation related with the opening of an artificial channel: The Valo Grande Delta, SE Brazil

The role played by human activity in coastline changes indicates a general tendency of retreating coasts, especially deltaic environments, as a result of the recent trend of sea level rise as well as the blockage of the transfer of sediments towards the coast, especially due to the construction of dams. This is particularly important in deltaic environments which are suffering a dramatic loss of area in the last decades. In contrast, in this paper, we report the origin and evolution of an anthropogenic delta, the Valo Grande delta, on the south-eastern Brazilian coast, whose origin is related to the opening of an artificial channel and the diversion of the main flow of the Ribeira de Iguape River. The methodology included the analysis of coastline changes, bathymetry and coring, which was used to determine the sedimentation rates and grain-size changes over time. The results allowed us to recognize the different facies of the anthropogenic delta and to establish its lateral and vertical depositional trends. Despite not being very frequent, anthropogenic deltas represent a favorable environment for the record of natural and anthropogenic changes in historical times and, thus, deserve more attention from researchers of different subjects
