Sea lice (Copepoda: Caligidae) and its Implications in Aquaculture
No full textSea lice including Caligus and Lepeophtheirus (Crustacea, Copepoda, Caligidae) are considered as serious pathogens of cultured fish, causing diseases and economic losses in fish aquaculture worldwide (Rosenberg, 2008). In Korea, some of the important cultured/farmed fishes are infected with pathogenic sea lice, but studies are scanty. Tongyeong marine living resources research & conservation center (TMRC), KIOST, the ranched marine fishes have recently been screened to study the infection of sea lice and its ecology.Identified sea lice are Caligus sclerotinosus Roubal, Armitage & Rohde, 1983 and Lepeophtheirus elegans Gusev, 1951. Here, we report the infection of both sea lice, ecology and its possible life cycle. (1) Caligus sclerotinosus was found infected on the body surface of P. major (Sparidae). Prevalence was 100%, mean and maximum intensites were 7.06 and 49, respectively. Adult females, males and few chalimi were observed and identified by their morphology. As an average of all our collections, less than 0.6% of individuals were chalimi. We suggest, therefore, that adults of C. sclerotinosus undergo ontogenetic host switching after their final moult (Venmathi Maran et al. 2012) (2) Lepeophtheirus elegans was found infected on the body surface and fins of S. schlegelii (Sebastidae). Prevalence was 98.8%, mean and maximum intensities were 6.45 and 29, respectively. Some hosts were found with lesions and severe infection of L. elegans and C. sclerotinosus may cause secondary infection on its host (Venmathi Maran et al. 2013). There have been no reports on sea lice infection from farmed red seabream and Korean rockfish and hence, it is a first report on the infection of C. sclerotinosus in Korea and a new host record for L. elegans (Venmathi Maran et al. 2012, 2013).fected on the body surface of P. major (Sparidae).

The Negro in the novels of Rene Maran, 1940
No full textThis study of the Negro in the novels of Rene Maran, Frances most prominent contemporary Negro author, is one of several being made at Atlanta University on the Negro in French literature. This attempt to-show how a Negro, the only one ever to receive the Prix Goncourt, portrays his African brothers, is the first American study of Rene Maran's novels. It is hoped that it will be a modest contribution to an almost unexplored field in French literature and that other students of France and her culture will be inspired to make a more extensive study of Rene Maran and his works. The first chapter is devoted to the life of Rene Maran and a discussion of his style and most important works. The second chapter presents the physical characteristics of the Negro as portrayed by Rene' Maran. Emphasis is placed on physical appearance, tribal marks, dress, disease and odors which seem to be especially characteristic of the Negro. The third chapter is devoted to the social characteristics of the Negro with emphasis on home life, food, religion, feasts, and governments. The last chapter will present a summary of the findings of this study. The appendix includes short synopses of each of the novels with Negro characters, and a latter from Monsieur Maran to the writer. aIt is to be regretted that such a small amount of material has been written on Rene Maran. Because of his modesty he has written even less about himself. Biographical material consists principally of Leon Bocquet's "Preface" to le Petit Roi de Chimerie, a fairy story by Rene Maran; le Coeur serre, an autobiography written as a novel; several articles which have appeared in periodicals and the forementioned letter from Monsieur Maran. First editions of all novels, with exception of Le Livre de la brousse, were used. As the latter was unavailable, the second edition (1937) was used. Rene Maran's most important novels on Africa, Batouala, Djouma, Chien de brousse, Le Journal sans date end le Livre de la brousse have been studied. The novelettes Bokorro and Bassarragba have also been used as references but the longer novels have constituted our major interest. Le Petit Roi de Chimerie , though it contains no Negro characters, was quoted because of one excellent example of Rene Maran's style. Less stress has been placed on Le Journal sans date because only one of its characters is a Negro. The writer sincerely appreciates the kindness and help of Rene Maran, whose letter was a source of constant encouragement
Stimulated Brillouin scattering threshold in double-clad fibers with various cladding shapes
Get PDFWe present a detailed numerical investigation about the stimulated Brillouin scattering (SBS) threshold power of double-clad optical fibers having different inner-cladding shapes. Generally, fibers with broken symmetry inner-cladding are usually employed in fiber lasers and amplifier in order to enhance pump light absorption by the doped core [1]. The acoustic response of such geometries is not known because their numerical characterizations are complicated. Even more difficulties occur when the fiber possess an acoustic anti-waveguide core since in that case the Brillouin response is often ruled by very high-order modes

René Maran critique littéraire
Get PDFLes travaux consacrés à René Maran abordent rarement l'activité critique de l'auteur. Outre ses qualités de poète, de romancier, de nouvelliste et fabuliste, d'essayiste, Maran s'est également adonné à la critique littéraire, dans des revues et journaux. C'est cet aspect de l'homme que je souhaite analyser dans les revues Europe, Les Lettres françaises et Présence africaine ainsi que les lettres inédites à Frédéric Jacques Temple, à la fin des années 1940 autour d’Un homme pareil aux autres. Que ressort-il de la lecture de ces articles ? Quelles facettes de l’homme/artiste/esthète révèlent-ils ? Que nous apprennent-ils des affinités intellectuelles de Maran, de ses vues sur la littérature en général et sur celle de l’outre-mer en particulier ? The works devoted to René Maran rarely address his activity as a literary critic. Besides having been a poet, an author, a novelist and a fabulist, an essayist, Maran also devoted himself to literary criticism in journals and publications. We would like to analyze this dimension of his work in the following journals Europe, Les Lettres françaises, Présence africaine, as well as in unpublished letters to Frédéric Jacques Temple, at the end of the 1940s. What comes out of reading these articles? What aspects of the man/artist/aesthete do they reveal? What do they teach us about Maran's intellectual affinities, his views on literature in general and that of Overseas France in particular

René Maran - Mohammed Dib
No full textRené Maran et Mohammed Dib ne se sont jamais rencontrés. Une génération les sépare, outre leur appartenance à un champ géographique différent. Maran a pourtant consacré une note de lecture fort intéressante au premier roman de Mohammed Dib. Sa recension consacrée à La Grande Maison, roman paru au printemps 1952, publiée dans La Corrèze républicaine le 20 juin 1952 lui a permis de formuler certains paramètres inhérents à sa vision idéologique et politique.René Maran and Mohammed Dib have never met. A generation separates them, apart from their belonging to a different geographical field. Maran has nevertheless devoted a very interesting reading note to Mohammed Dib’s first novel. His review of La Grande Maison, a novel published in the spring of 1952 and published in La Corrèze républicaine on 20 June 1952, allowed him to formulate certain parameters inherent to his ideological and political vision
