Swimming is one of the most common sports activities in Walloon region as in many countries (Bodson, 1997). According to Boullé (1999) swimming courses concern various sectors of practice: the awakening (blooming of the person), the discovery (educational purposes), the improvement (to pass a test or to carry out a performance), the leisure and maintenance (relaxation or improvement of the form and health), the practice in natural environment. Additionally, swimming is a prerequisite to other sports and cultural activities. Considering its place in individual safety, education, health and leisure, its importance in child and youth development is unchallenged. [less ▲]

A coordinated action involving eleven stations of the ground -based Network for Detection of Stratospheric Change (NDSC) equipped with Fourier transform infrared (FTIR) instruments was conducted to contribute to the validation of the three atmospheric chemistry instruments onboard ENVISAT, that are MIPAS, SCIAMACHY and GOMOS. The target products for validation are total columns of O3, CH4, CO and some important NOy species (NO2, HNO3, NO) and the source gas N2O. Together the eleven stations cover the latitudes between 79 °N and 78°S, including polar, mid-latitude and subtropical and tropical locations. The goal is to contribute to the assessment of the data quality of the aforementioned ENVISAT instruments, from a quasi -global perspective. The period of intensive ground-based data collection for the benefit of the ENVISAT Validation Commissioning Phase that is dealt with in the present paper is July 15 to December 1, 2002. The FTIR network involved collected a data set corresponding to an equivalent of approximately 400 days of measurements; about three quarter of the data have already been submitted to the ENVISAT Calval database and are included in the present work. Unfortunately, the distribution of ENVISAT data has been slow and limited. Only a limited number of coincidences has been found for making data inter -comparisons. Therefore, the conclusions drawn in this paper are very preliminary and cover only a limited set of data products from SCIAMACHY only. Our findings up to now concerning the above mentioned target products are the following: (1) SCIAMACHY near infrared operational products (CO, CH4, N 2O) have no scientific meaning yet, (2), the operational SCIAMACHY total vertical O3 column product derived in the ultraviolet window has undergone some improvements with changing versions of the processor(s) but it still underestimates the column by about 5 – 10 %, (3), the operational SCIAMACHY total vertical O3 column product derived in the visible window is unrealistically large, and (4), the operational NO2 total column product from SCIAMACHY seems to largely overestimate the real column, but very few coincidences and large dispersions of the data do inhibit any further conclusion at present. In a next phase, the same ground-based correlative data set will be exploited to further validate the ENVISAT data as soon as more and reprocessed data will be distributed. [less ▲]

Language has always been a major issue for post-colonial writers, being at once an instrument used by the colonial power and one of the prime avenues of resistance to this oppression. For displaced West Indian writers in particular, English has been a significant tool for self-assertion, all the more ambiguous because it is their "mother tongue" while being the tongue of their ancestors' masters as well. This paper analyses how the younger novelists of the Caribbean diaspora use and transform the English language in their search for a new diasporic, cross-cultural identity. Robert Antoni, Michelle Cliff, Fred D'Aguiar, David Dabydeen, M. Nourbese Philip and Caryl Phillips will be among the writers mentioned in this paper. While some of them resort to non-standard linguistic forms and thereby deal head on with the tension between local languages and the need for international communication, others have had a more oblique approach to linguistic change, one that involves not so much lexis as tone and rhythm and often operates by rehabilitating silenced voices from the past. I will attempt to demonstrate how these writers have turned speech into a site of creolization expressive of what Caryl Phillips has called" A New World Order". [less ▲]

The adhesion of methyl ricinoleate droplets to cells of the yeast Yarrowia lipolytica was investigated. A new cytometric method, relying on the double staining of fatty globules with Nile Red and of cells with Calcofluor, enabled us to quantify methyl ricinoleate droplet adhesion to cells precultured on a hydrophilic or on a hydrophobic carbon source. In this last case, droplet adsorption was enhanced and a MATS (microbial adhesion to solvents) test revealed that this increase was due to Lewis acid-base interactions and not to an increase in the hydrophobic properties of the cell surface. These preliminary results demonstrate that the developed cytometric method is promising for various applications concerning the study of interactions between microorganisms and an emulsified hydrophobic substrates.

Aims: To study the fundamental mechanisms of toxicity of the fruity aroma compound γ-decalactone, that lead to alterations in cell viability during its biotechnological production by yeast cells; Yarrowia lipolytica that is able to produce high amounts of this metabolite was used here as a model. Methods and Results: Lactone concentrations above 150 mg l-1 inhibited cell growth, depolarized the living cells and increased membrane fluidity. Infrared spectroscopic measurements revealed that the introduction of the lactone into model phospholipid bilayers, decreased the phase transition temperature. Moreover, the H+-ATPase activity in membrane preparations was strongly affected by the presence of the lactone. On the other hand, only a slight decrease in the intracellular pH occurred. Conclusions: We propose that the toxic effects of γ-decalactone on yeast may be initially linked to a strong interaction of the compound with cell membrane lipids and components. Significance and Impact of the Study: These findings may enable the elaboration of strategies to improve yeast cell viability during the process of lactones bioproduction. [less ▲]

Both diversity and density of lacewings depend on prey availability but also on plant composition near crops. The impact of field borders vegetation on abundance and diversity of Syrphidae and Coccinellidae is well known but very few studies have been realised to assess its effect on the abundance and diversity of Chrysopidae. In 2000 and 2001, the impact of adjacent habitats on lacewing populations was investigated in both carrot and broad bean open fields. Three types of field borders were selected: (1) set-asides mainly composed by Lolium perenne and Trifolium spp., (2) crops (wheat, beet or other vegetables) and (3) woody areas (mixture of Acer sp., Populus sp. and Salix sp.). Insects were caught using yellow pan traps. Chrysopidae populations were shown to be significantly lower in carrot and broad bean fields bordered with woodland. Lacewing and other Neuroptera species richness were always low and were discussed in relation with their role of pest predators associated with other aphidophagous insects. [less ▲]

The γ- and δ-lactones of less than 12 carbons constitute a group of compounds of great interest to the flavour industry. It is possible to produce some of these lactones through biotechnology. For instance, γ-decalactone can be obtained by biotransformation of methyl ricinoleate. Among the organisms used for this bioproduction, Yarrowia lipolytica is a yeast of choice. It is well adapted to growth on hydrophobic substrates, thanks to its efficient and numerous lipases, cytochrome P450, acylCoA oxidases and its ability to produce biosurfactants. Furthermore, genetic tools have been developed for its study. This review deals with the production of lactones by Y. lipolytica with special emphasis on the biotransformarion of methyl ricinoleate to γ-decalactone. When appropriate, information from the lipid metabolism of other yeast species is presented. [less ▲]

Abstract Analysis of the whole set of human genes reveals that most of them present TA and GC skews, that these biases are correlated to each other and are speci¢c to gene sequences, exhibiting sharp transitions between transcribed and non-tran- scribed regions. The GC asymmetries cannot be explained solely by a model previously proposed for (G+T) skew based on tran- sitions measured in a small set of human genes. We propose that the GC skew results from additional transcription-coupled mu- tation process that would include transversions. During evolu- tion, both processes acting on a large majority of genes in germ- line cells would have produced these transcription-coupled strand asymmetries. [less ▲]
