When Jane Austen wrote in January 1801 that ‘Mrs Powlett was at once expensively and nakedly dressed’, the fashion for muslin dresses had existed for some eighteen years. This article examines the crucial period between 1779 and 1784 when the muslin garment, which became known as the chemise à la reine, was developed and refined. Originating in the French West Indies, the gaulle was the ‘colonial livery’ worn by the wives of the white elite, the ‘grands blancs’, and first appeared as a costume in a ballet performed in Paris in 1779. The version worn by Queen Marie Antoinette in Vigée Le Brun's controversial portrait of 1783 provoked, according to the Baron de Frénilly, ‘a revolution in dress’ which eventually destabilized society. The article focuses on the role played by Saint-Domingue, France's most valuable overseas possession, in the transference of the gaulle from colonial to metropolitan fashion, and how the colony became one of the major providers of unprocessed cotton to the French cotton industry.

The review presents data on the location, nature, properties, number, and expression of carbonic anhydrase genes in the photosynthesizing cells of C3 plants. The available data about the presence of carbonic anhydrases in plasma membrane, cytoplasm, mitochondria, chloroplast stroma and thylakoids are scrutinized. Special attention was paid to the presence of carbonic anhydrase activities in the different parts of thylakoids, and on collation of sources of these activities with enzymes encoded by the established genes of carbonic anhydrases. The data are presented to show that the consistent incorporation of carbonic anhydrases belonging to different families of these enzymes forms a coherent system of CO2 molecules transport from air to chloroplasts in photosynthesizing cells, where they are included in organic molecules in the carboxylation reaction. It is discussed that the manifestation of the activity of a certain carbonic anhydrase depends on environmental conditions and the stage of ontogenesis.

The Stability

Manufactured nanoparticles (MNPs) are increasingly released into the environment and thus research on their fate and behaviour in complex environmental samples is urgently needed. The fate of MNPs in the aquatic environment will mainly depend on the physico-chemical characteristics of the medium. The presence and concentration of natural organic matter (NOM) will play a significant role on the stability of MNPs by either decreasing or exacerbating the aggregation phenomenon. In this study, we firstly investigated the effect of NOM concentration on the aggregation behaviour of manufactured Fe-oxide nanoparticles. Then, the stability of the coated nanoparticles was assessed under relevant environmental conditions. Flow field-flow fractionation, an emerging method which is gaining popularity in the field of nanotechnology, has been employed and results have been compared to another size-measurement technique to provide increased confidence in the outcomes. Results showed enhanced stability when the nanoparticles are coated with NOM, which was due to electrosteric stabilisation. However, the presence of divalent cations, even at low concentration (i.e. less than 1 mM) was found to induce aggregation of NOM-coated nanoparticles via bridging mechanisms between NOM and Ca2+.

The third session of the West Indian Conference opened at Guadeloupe, French West Indies on December 1, 1948 and closed on December 14, after considering policy to be followed by the Caribbean Commission for the next two years. The Conference was attended by two delegates from each of the fifteen territories within the jurisdiction of the commission and observers invited by the commission from Haiti, Cuba, the Dominican Republic, and the United Nations and its specialized agencies.
