Management of a tributyl tin issue in a marina development in Queensland

Tributyl tin (TBT) deposits in the sediments are one of many impacts that have been imposed on both the environment and the up-coming development of Boat Haven, Airlie Beach, Queensland. The current costly solution to this problem (that is, removal and re-burial) could be put in future to the credit of the developer rather than be treated (as at present) as a penalty. The Queensland Government’s Offsets Scheme provides an opportunity to promote effective conservation of regional landscapes. Because this scheme plans for offsetting in terrestrial vegetation systems through rehabilitation, so credits could be given to those approved developers who rehabilitate valuable marine habitats disturbed by TBT deposits.

Ecological design with respect to the environment of large-scale marina developments in Queensland

Ecological principles have been employed to assist in the sustainability of a suite of 'gateway' marinas currently being developed in Queensland. Tasks included (a) location and fostering of core remnant native vegetation areas, (b) understanding the dynamic patterns of region behaviour using the ecological strategies employed by key flora and fauna species, (c) promoting those native wildlife species best characterising the region, and (d) allocating management actions along elongated buffer zones to the catchment headwaters (rather than only peripheral to the property). The design of infrastructure and its relationship to sustainable landscape development is lacking such a response int eh planning and detailing of new marinas. This paper distinguishes between the practice of landscape ecology and the design of ecological landscapes, offering examples of the principles of the latter in support of the concept of ecological landscape practice.

Improving information in project appraisal using hedonic pricing : a case study of marina berthing charges

Hedonic pricing techniques can be used to generate quantitative information useful to the project appraiser at various stages of the project cycle, most notably project formulation and investment appraisal. To illustrate, a hedonic pricing model is applied to marina berthing charges in England and Wales. The technique determines the relevant marina facilities that are reflected in marina rental price. The contribution of the key marina facilities is expressed in monetary terms as the contribution to cost per overall rental price per foot.

Patterns of Transcendence : Classical Myth in Marina Tsvetaeva's Poetry of the 1920s

This study examines the position and meaning of Classical mythological plots, themes and characters in the oeuvre of the Russian Modernist poet Marina Tsvetaeva (1892-1941). The material consists of lyric poems from the collection Posle Rossii (1928) and two longer lyrical tragedies, Ariadna (1924) and Fedra (1927). These works are examined in the context of Russian Modernism and Tsvetaeva s own poetic development, also taking into account the author s biography, namely, her correspondence with Boris Pasternak. Tsvetaeva s appropriations of the myths enter into a dialogue with the Classical tradition and with the earlier Russian and Western literary manifestations of the source material. Her Classical texts are inextricably linked with her own authorial myth, they are used to project both her ideas about poetry as well as the authored self of her poems. An important context for Tsvetaeva s application of the Classical myths is the concept of the Platonic ladder of Eros. This plot evokes the process of transcendence of the mortal subject into the immaterial realm and is applied by the author as an extended metaphor of the poet s birth. Emphasizing the dialectical movement between the earthly and the divine, Tsvetaeva s Classical personae foreground various positions of the individual between these two realms. By means of kaleidoscopic reformulations of similar metaphors and concepts, Tsvetaeva s mythological poems illustrate the poet s position between the material and the immaterial and the various consequences of this dichotomy on the creative mission. At the heart of Tsvetaeva s appropriation of the Sibyl, Phaedra, Eurydice and Ariadne is the tension between the body and disembodiment. The two lyrical tragedies develop the dichotomous worldview further, nevertheless emphasizing the dual perspective of the divine and the earthly realms: immaterial existence is often evaluated from a material perspective and vice versa. The Platonic subtext is central for Ariadna, focussing on Theseus development from an earthly hero to a spiritual one. Fedra concentrates on Phaedra s divinely induced physical passion, which is nevertheless evoked in a creative light.

Fabricación de una boya marina en biocomposite de fibra y resina naturales

En el presente TFG se ha construido una boya marina con fibras de lino y resina de origen natural. Para ello en el TFG se ha seguido el esquema para un estudio experimental dividido principalmente en tres puntos: Memoria ( Introducción, Estado del arte, Objetivos, Parte experimental, Conclusiones, Futuros estudios), Presupuesto (Fabricación del molde y de la boya) y Anexos (Fichas técnicas y de seguridad de los materiales). La idea de fabricar una boya marina en biocomposites surge de la diversidad de aplicaciones que estas tienen y como visión medioambiental, siendo esta una alternativa al uso de polimeros dependientes del petróleo. Para su construcción primero se ha fabricado un molde con fibra de vidrio, mediante el método de moldeo por contacto a mano, a partir de una boya de polietileno. Y sobre este molde, mediante el método de infusión, se ha fabricado la mitad de la boya marina con biocomposites.

A representação dos atores sociais e a imagem da mulher no contexto do discurso feminista em contos de Marina Colasanti

O livro Contos de amor rasgados, de Marina Colasanti, foi publicado em 1986, década de consolidação das conquistas do movimento feminista (Pinto, 2003). O feminismo almejava uma mudança de mentalidade, mudança nas práticas sociais e nos discursos sobre a mulher (ibid.). Entretanto, a mulher nos contos é representada de forma peculiar, frustrando as expectativas de uma imagem positiva esperada de uma literatura produzida por uma autora feminista. Este estudo propõe a análise dos contos de Marina Colasanti, destacando algumas questões acerca da representação dos atores sociais em textos-contos que pretendem veicular um discurso de liberação da mulher. Para tanto, dez contos representativos do todo foram selecionados para compor o corpus e utilizou-se o sistema sociossemântico para a representação dos atores sociais proposto por van Leeuwen (1997) e a Linguística Sistêmico Funcional de Halliday (2004) como ferramentas de análise. Nosso enfoque é o da Análise Crítica do Discurso de Fairclough (1995), que tem dedicado seus estudos às mudanças sociais através dos discursos. Consideramos que o movimento feminista se inscreve em algumas mudanças. Nessa perspectiva, Bourdieu (2005) afirma que, apesar do movimento feminista, muito pouco mudou, prevalecendo, ainda, a dominação masculina e a violência simbólica. As categorias de van Leeuwen (op. cit.) da exclusão e inclusão dos atores sociais no discurso servem de instrumental para uma análise mais detalhada das relações homem-mulher, permitindo desvelar algumas questões feministas tematizadas nos contos, questões descritas por Pinto (op. cit.) e apontadas por Bourdieu (op. cit.). Os resultados da análise dos contos demonstram que a mulher ora está totalmente excluída, ora é representada como um pano de fundo (encobrimento), ora é enfraquecida (apassivada) em favor de seu marido/amante. Assim, os conflitos gerados a partir das ações do homem sobre a mulher nos contos confirmam certas preocupações do discurso feminista

Nos fios das narradoras: tramas e urdiduras do feminino nos contos de fadas de Angela Carter e Marina Colasanti

Essa dissertação tem como objetivo a leitura comparativa dos contos de fadas da escritora inglesa Angela Carter, contidos no livro O quarto do Barba Azul, e os da ítalo-brasileira Marina Colasanti, presentes em livros como Uma ideia toda azul, Entre a rosa e a espada, Doze reis e a moça no labirinto do vento. Foram analisadas os modos pelo quais as duas autoras, através da reescrita dos contos de fadas, resistem a morte do narrador tradicional descrita por Walter Benjamin e criticam a sociedade patriarcal, revelando, naturalmente, uma postura feminista. Identificou-se, ainda, como estratégias poéticas comuns à escrita de ambas as autoras, aspectos intertextuais como a paródia, o palimpsesto e o pastiche

The Status of Eelgrass, Zostera marina, as Bay Scallop Habitat: Consequences for the Fishery in the Western Atlantic

Zostera marina is a member of a widely distributed genus of seagrasses, all commonly called eelgrass. The reported distribution of eelgrass along the east coast of the United States is from Maine to North Carolina. Eelgrass inhabits a variety of coastal habitats, due in part to its ability to tolerate a wide range of environmental parameters. Eelgrass meadows provide habitat, nurseries, and feeding grounds for a number of commercially and ecologically important species, including the bay scallop, Argopecten irradians. In the early 1930’s, a marine event, termed the “wasting disease,” was responsible for catastrophic declines in eelgrass beds of the coastal waters of North America and Europe, with the virtual elimination of Z. marina meadows in the Atlantic basin. Following eelgrass declines, disastrous losses were documented for bay scallop populations, evidence of the importance of eelgrass in supporting healthy scallop stocks. Today, increased turbidity arising from point and non-point source nutrient loading and sediment runoff are the primary threats to eelgrass along the Atlantic coast and, along with recruitment limitation, are likely reasons for the lack of recovery by eelgrass to pre-1930’s levels. Eelgrass is at a historical low for most of the western Atlantic with uncertain prospects for systematic improvement. However, of all the North American seagrasses, eelgrass has a growth rate and strategy that makes it especially conducive to restoration and several states maintain ongoing mapping, monitoring, and restoration programs to enhance and improve this critical resource. The lack of eelgrass recovery in some areas, coupled with increasing anthropogenic impacts to seagrasses over the last century and heavy fishing pressure on scallops which naturally have erratic annual quantities, all point to a fishery with profound challenges for survival.

Removal of Sea Lettuce, Ulva spp., in Estuaries to Improve the Environments for Invertebrates, Fish, Wading Birds, and Eelgrass, Zostera marina

Mats (biomasses) of macroalgae, i.e. Ulva spp., Enteromorpha spp., Graciolaria spp., and Cladophora spp., have increased markedly over the past 50 years, and they cover much larger areas than they once did in many estuaries of the world. The increases are due to large inputs of pollutants, mainly nitrates. During the warm months, the mats lie loosely on shallow sand and mud flats mostly along shorelines. Ulva lactuca overwinters as buds attached to shells and stones, and in the spring it grows as thalli (leaf fronds). Mats eventually form that are several thalli thick. Few macroinvertebrates grow on the upper surfaces of their thalli due to toxins they produce, and few can survive beneath them. The fish, crabs, and wading birds that once used the flats to feed on the macroinvertebrates are denied these feeding grounds. The mats also grow over and kill mollusks and eelgrass, Zostera marina. An experiment was undertaken which showed that two removals of U. lactuca in a summer from a shallow flat in an estuarine cove maintained the bottom almost free of it.
