In the 10-mer RNA duplex model system a 4-isocyano TEMPO spin-label is individually attached to one strand and two strands are annealed to measure distances. This methodology is limited to systems in which two oligonucleotides are annealed together. To circumvent this limitation and also to explore single-strand dynamics a new methodology was implemented, double spin-labeling. Double spin-labeled single-stranded RNA was investigated as a single-strand and within a duplex via MALDI-TOF-MS, EPR spectroscopy and RP-HPLC. A double spin-labeling strategy in this work will be applicable to large complex RNAs like Group I intron of Tetrahymena thermophilia. Captain Daniel Lawrence, was one of four sloops detailed to serve as a transport to supply the British Florida garrisons. The Industry ran aground on the bar outside of St. Augustine's harbour on May 6, 1764. The transport was carrying six-pound cannons, ammunition and artificer's tools. Further investigation of documents describing eighteenth-century trade and shipping to St. Augustine led to the discovery that the Lawrence family of sea captains provided a vital link between British New York and Spanish St. Augustine. An examination of the materials recovered from Site 8SJ3478 sheds light on exactly what a particular vessel carried during a period of transition in Florida's history.

This thesis examines and compares German and British trade union responses in a European context following the recent European enlargements which are unprecedented in the history of the European Union. In terms of labour law, a majority of the ten Central and Eastern European countries which acceded in 2004 and 2007 combine weak domestic labour protection systems with a high proportion of workers and enterprises keen to take advantage of their free movement rights under the European Treaty. This has created a climate of fear amongst workers and trade unions in old Member States that their economic and social position is being threatened by those workers and enterprises who may avail themselves of their rights under the Treaty in order to engage in ‘social dumping’. Historically, the European Union has sought to counteract these fears by ‘europeanising’ certain aspects of national legal systems in order to alleviate competition. However, the ‘europeanisation’ of different labour law systems has always proved problematic due to the socio-cultural context within which national labour laws have developed. Following the recent European enlargements, the debate on the role of the EU in ‘europeanising’ national social and legal practices has been revived. In particular, European enlargement has thrown up changed regulatory and opportunity structures for the social partners. These structural changes at a European level have occurred primarily as a consequence of an increase in the free movement of workers, services and establishment. Against this background, the purpose of this thesis is to undertake a comparison of the responses of German and British trade unions to the challenges posed by the recent European enlargements. A successful comparison and analysis of the responses of trade unions enables a determination of the impact that trade union responses may have on new Member State workers availing themselves of their free movement rights under the EU Treaty. There is an intense debate as to how, and if, social partners at a national and European level may be able to contribute to, or hinder, the protection of new Member State workers in Germany and the UK. Depending on how trade unions respond their contribution may be viewed as positive or negative. However, this thesis yields suggestions as to how trade unions could respond in order to facilitate the integration of new Member State workers into the host labour markets and proposes a new model for studying aspects of europeanisation.
