Mass culture of marine diatom Skeletonema costatum (Greville) Cleve collected from the Bay of Bengal

The growth of Skeletonema costatum in two artificial nutrient media was studied using various culture vessels. Skeletonema costatum was collected from the Cox's Bazar coast around the Bay of Bengal. Different growths stages i.e. lag phase, exponential phase, prestationary phase, stationary and death phase were observed during the culture period. The number of cells increased during the active division period and decreased after the beginning of the prestationary phase. The average densities of S. costatum in primary and secondary cultures were 0.55 x 10 super(6) cells mlˉ¹ and 0.93x10 super(6) cells mlˉ¹, respectively. In mass culture of S. costatum two, types of media were used. Highest cells densities of S. costatum cement tank culture were recorded 1.23x10 super(6) cell mlˉ¹ and 0.78x10 super(6) cells mlˉ¹ in their respective f/4 medium and commercial fertilizer medium. In the cement tanks culture fertilizer medium was found to be the best medium for mass culture of S. costatum in respect of production efficiency and culture stability.

Mass culture of Undaria gametophyte clones and their use in sporeling culture

Undaria pinnatifida (Harv.) Sur. is one of the three main seaweed species under commercial cultivation in China. In the mid-1990s the annual production was about 20000 tons dry. The supply of healthy sporelings is key to the success of commercial cultivation of Undaria. Previous studies demonstrated that instead of the zoospore collection method, sporelings can be cultured through the use of gametophyte clones. This paper reports the experimental results on mass culture of clones and sporeling raising in commercial scale. Light had an obvious effect on growth of gametophyte clones. Under an irradiance of 80 mumol m(-2) s(-1) and favorable temperature of 22-25degreesC, mean daily growth rate may reach as high as 37%. Several celled gametophyte fragments were sprayed onto the palm rope frame. Gametogenesis occurred after 4-6 days. Juvenile sporeling growth experiments showed that nitrate and phosphate concentrations of 2.9 10(-4) mol 1(-1) and 1.7 10(-5) mol 1(-1) were sufficient to enable the sporelings to maintain a high daily growth rate. Sporelings can reach a length of 1 cm in a month. Since 1997, extension of the clone technique has been carried out in Shandong Province. Large-scale production of sporelings for commercial cultivation of 14 and 31 hectares in 1997 and 1998 had been conducted successfully.

A simple and low-cost airlift photobioreactor for microalgal mass culture

A simple, low-cost, and efficient airlift photobioreactor for microalgal mass culture was designed and developed. The reactor was made of Plexiglas, and composed of three major parts: outer tube, draft tube and air duct. The fluid-dynamic characteristics of the airlift reactor were studied. The system proved to be well suited to the mass cultivation of a marine microalga, Chlorella sp. In batch culture, the biomass volumetric output rate of 0.21 g l(-1) d(-1) was obtained at the superficial gas velocity of 4 mm s(-1) in the draft tube.

Symbiotic Cities: Buenos Aires, Montevideo, and Mass Culture, 1910-1960

This dissertation examines how Buenos Aires emerged as a creative capital of mass culture and cultural industries in South America during a period when Argentine theater and cinema expanded rapidly, winning over a regional marketplace swelled by transatlantic immigration, urbanization and industrialization. I argue that mass culture across the River Plate developed from a singular dynamic of exchange and competition between Buenos Aires and neighboring Montevideo. The study focuses on the Argentine, Uruguayan, and international performers, playwrights, producers, cultural impresarios, critics, and consumers who collectively built regional cultural industries. The cultural industries in this region blossomed in the interwar period as the advent of new technologies like sound film created profitable opportunities for mass cultural production and new careers for countless theater professionals. Buenos Aires also became a global cultural capital in the wider Hispanic Atlantic world, as its commercial culture served a region composed largely of immigrants and their descendants. From the 1920s through the 1940s, Montevideo maintained a subordinate but symbiotic relationship with Buenos Aires. The two cities shared interlinked cultural marketplaces that attracted performers and directors from the Atlantic world to work in theatre and film productions, especially in times of political upheaval such as the Spanish Civil War and the Perón era in Argentina. As a result of this transnational process, Argentine mass culture became widely consumed throughout South America, competing successfully with Hollywood, European, and other Latin American cinemas and helping transform Buenos Aires into a cosmopolitan metropolis. By examining the relationship between regional and national frames of cultural production, my dissertation contributes to the fields of Latin American studies and urban history while seeking to de-center the United States and Europe from the central framing of transnational history.

Culture experiments on the copepod, Tisbintra elongata MORI, and evaluation of that species as food organism for milkfish larvae

Five types of food were used to culture T. elongata: rice bran, cow dung, bread, cow dung, bread yeast, fermented fish solubles and Spirulina. Bread yeast was found to give the highest densities. An evaluation was also made of the effectivity of rice bran and fermented fish solubles for the outdoor mass culture of T. elongata . A comparative study on the growth and survival rate of milkfish fry (Chanos chanos) fed with T. elongata and Artemia showed there to be no significant differences between the diets.

Growth kinetics of 1-2 mm and 3-4 mm colonies of Nostoc sphaeroides (Cyanophyta) in outdoor culture

Nostoc sphaeroides Kutzing was cultivated in paddlewheel-driven raceway ponds and the growth kinetics of 1-2 mm and 3-4 mm colonies of N. sphaeroides was studied. The biomass productivities in 2.5 m(2) raceway ponds inoculated with 1-2 mm and 3-4 mm colonies were 5.2 and 0.25 g dry wt m(-2) stop d(-1), respectively. Furthermore, differently sized colonies showed different relative water content, total soluble carbohydrates, chlorophyll a content and density of filaments. This is the first report on mass culture of N. sphaeroides under outdoor conditions.

Transatlantic negotiations on "hell"?: W. E. B. Du Bois's visit to fascist Germany and Theodor W. Adorno's exile in the land of the culture industry

In 1936, the African-American intellectual W.E.B. Du Bois visited Nazi Germany for a period of five months. Two years later, the eleven-year-long American exile of the German philosopher Theodor W. Adorno began. From the latter’s perspective, the United States was the “home” of the Culture Industry. One intuitively assumes that these sojourns abroad must have amounted to “hell on earth” for both the civil rights activist W.E.B. Du Bois and the subtle intellectual Adorno. But was this really the case? Or did they perhaps arrive at totally different conclusions? This thesis deals with these questions and attempts to make sense of the experiences of both men. By way of a systematic and comparative analysis of published texts, hitherto unpublished documents and secondary literature, this dissertation first contextualizes Du Bois’s and Adorno’s transatlantic negotiations and then depicts them. The panoply of topics with which both men concerned themselves was diverse. In Du Bois’s case it encompassed Europe, science and technology, Wagner operas, the Olympics, industrial education, race relations, National Socialism and the German Africanist Diedrich Westermann. The opinion pieces which Du Bois wrote for the newspaper “Pittsburgh Courier” during his stay in Germany serve as a major source for this thesis. In his writings on America, Adorno concentrated on what he regarded as the universally victorious Enlightenment and the predominance of mass culture. This investigation also sheds light on the correspondences between the philosopher and Max Horkheimer, Thomas Mann, Walter Benjamin, Siegfried Kracauer and Oskar and Maria Wiesengrund. In these autobiographical texts, Adorno’s thoughts revolve around such diverse topics as the American landscape, his fears as German, Jew and Left-Hegelian as well as the loneliness of the refugee. This dissertation has to refute the intuitive assumption that Du Bois’s and Adorno’s experiences abroad were horrible events for them. Both men judged the foreign countries in which they were staying in an extremely differentiated and subtle manner. Du Bois, for example, was not racially discriminated against in Germany. He was also delighted by the country’s rich cultural offerings. Adorno, for his part, praised the U.S.’s humanity of everyday life and democratic spirit. In short: Although both men partly did have to deal with utterly negative experiences, the metaphor of “hell on earth” is simply untenable as an overall conclusion.

The (ab)use of politics and eroticism in the culture of the Spanish Transition to democracy (1975–1982)

This dissertation analyzes the (ab)use of politics and eroticism within the framework of the Transition to democracy in Spain, its social and cultural impact—on literature, film, music, and popular media—, and its consequences. After a period of nearly four decades, when the country was subjected to a totalitarian regime, Spanish society underwent a process of democratic restoration. As a result, the two topics considered taboo during almost forty years of repression—i.e., politics and sexuality/eroticism—, gushed out fiercely. Every aspect of culture was influenced by and intrinsically linked to them. However, while we have been offered a more or less global approach to the Transition—the Transition as a whole—, and some studies have focused on diverse areas, no research to date has covered in depth the significance of those issues during that historical moment. Considering the facts stated above, it was imperative to conduct a more detailed analysis of the influence of both eroticism and politics on the cultural production of the Transition from different perspectives. Although the academic intelligentsia has often rejected them as expressions of mass culture, we must consider Pierre Bourdieu’s theories—in line with the tradition of classical sociology, that includes science, law, and religion, together with artistic activities—, Michel Foucault’s ideas on sexuality, and New Historicism, examining texts and their contexts. This work concludes that the (ab)use of both subjects during the Spanish Transition was a reaction to a repressive condition. It led to extremes, to societal transgression and, in most cases, to the objectification of women because of the impositions of a patriarchal society. It was, however, part of a learning and, in a sense, cathartic process that led, eventually, to the reestablishment of the status quo, to a more equitable and multicultural society where men, women, and any political or sexual tendencies are respected—at least, in theory.

Cutting on action : interference strategies in contemporary art practice

The domestication of creative software and hardware has been a significant factor in the recent proliferation of still and moving image creation. Booming numbers of amateur image-makers have the resources, skills and ambitions to create and distribute their work on a mass scale. At the same time, contemporary art seems increasingly dominated by ‘post-medium’ practices that adopt and adapt the representational techniques of mass culture, rather than overtly reject or oppose them. As a consequence of this network of forces, the field of image and video production is no longer the exclusive specialty of art and the mass media, and art may no longer be the most prominent watchdog of mass image culture. Intuitively and intentionally, contemporary artists are responding to these shifting conditions. From the position of a creative practitioner and researcher, this paper examines the strategies that contemporary artists use to engage with the changing relationships between image culture, lived experience and artistic practice. By examining the intersections between W.J.T. Mitchell’s detailed understanding of visual literacy and Jacques Derrida’s philosophical models of reading and writing, I identify ‘editing’ as a broad methodology that describes how practitioners creatively and critically engage with the field of still and moving images. My contention is that by emphasising the intersections of looking and making, ‘reading’ and ‘writing’, artists provide crucial jump cuts, pauses and distortions in the medley of our mediated experiences.

Art museums and the global tourist: Experience centres in experience-scapes

In the experience economy, the role of art museums has evolved so as to cater to global cultural tourists. These institutions were traditionally dedicated to didactic functions, and served cognoscenti with elite cultural tastes that were aligned with the avant-garde’s autonomous stance towards mass culture. In a post-avant-garde era however museums have focused on appealing to a broad clientele that often has little or no knowledge of historical or contemporary art. Many of these tourists want art to provide entertaining and novel experiences, rather than receiving pedagogical ‘training’. In response, art museums are turning into ‘experience venues’ and are being informed by ideas associated with new museology, as well as business approaches like Customer Experience Management. This has led to the provision of populist entertainment modes, such as blockbuster exhibitions, participatory art events, jazz nights, and wine tasting, and reveals that such museums recognize that today’s cultural tourist is part of an increasingly diverse and populous demographic, which shares many languages and value systems. As art museums have shifted attention to global tourists, they have come to play a greater role in gentrification projects and cultural precincts. The art museum now seems ideally suited to tourist-centric environments that offer a variety of immersive sensory experiences and combine museums (often designed by star-architects), international hotels, restaurants, high-end shopping zones, and other leisure forums. These include sites such as Port Maravilha urban waterfront development in Rio de Janiero, the Museum of Old and New Art in Hobart, and the Chateau La Coste winery and hotel complex in Provence. It can be argued that in a global experience economy, art museums have become experience centres in experience-scapes. This paper will examine the nature of the tourist experience in relation to the new art museum, and the latter’s increasingly important role in attracting tourists to urban and regional cultural precincts.

O clarim dos marginalizados. A literatura marginal/periférica na Literatura Brasileira Contemporânea

A presente dissertação tem como objetivo principal problematizar a questão da Literatura Marginal / Periférica e apresentá-la no âmbito da Literatura e das Culturas. Para a construção do trabalho, foram utilizados teóricos que trabalham e reveem conceitos de cultura, não cristalizados, tais como, Cultura Popular, Cultura de Elite e Cultura de Massa, tendo em vista uma concepção de mercado e de socialização da arte. Ao mesmo tempo, a fim de inserir este novo movimento literário no âmbito das artes e das instituições, foram feitas entrevistas e utilizadas obras literárias de três autores (Ferréz, Alessandro Buzo e Allan da Rosa) e de uma autora (Elizandra Souza) que atuam na cena literária marginal / periférica. Para sua concretização, o estudo toma como referência as indagações e as recepções diante das culturas e da indústria cultural, ao traçar um panorama de como este movimento vem atuando na Literatura Brasileira Contemporânea

Da pobreza à riqueza: a ascensão social de jogadores de futebol profissional

Esta pesquisa tem o objetivo de analisar o discurso de jogadores de futebol em atividade que emergiram socialmente mediante a prática profissional desse esporte para tentar identificar se há relação entre suas atitudes, suas dificuldades de adaptação ao exterior e o fato de serem oriundos de famílias com baixa renda. O estudo surgiu a partir da observação de reportagens dos meios de comunicação em que figuravam constantes aparições de jogadores reconhecidos socialmente não só pela fama e pelo sucesso dentro do futebol, mas também por alguns de seus comportamentos dentro e fora de campo. Como fundamentação teórica buscou-se principalmente contribuições de Edgar Morin, que apresenta o conceito de cultura de massa dentro do qual se inserem os chamados heróis modernos. O autor afirma que os jogadores de futebol bem-sucedidos figuram nessa categoria e discute a promoção dessas novas vedetes a partir das constantes informações midiáticas sobre suas rotinas. No que tange às teorias relativas ao esporte, e mais especificamente ao futebol, fundamentou-se o estudo a partir dos pensamentos de Mário Rodrigues Filho, que apresenta a ascensão do negro e do pobre no futebol brasileiro, esporte de origem branca e elitista. O esporte é, portanto, estudado sob uma perspectiva sociocultural com importante influência no Brasil e no mundo, sobretudo por meio do futebol. A metodologia utilizada foi a técnica de análise documental de conteúdo, optou-se pela interpretação de reportagens da fonte primária revista Placar. Como recorte, foram escolhidas as edições lançadas entre janeiro de 2009 e dezembro de 2011, configurando um total de trinta edições em três anos. A partir do levantamento das revistas citadas, foram selecionadas, ao final de toda a análise, 19 entrevistas de jogadores de futebol profissional divididas nas seguintes categorias: (i) ascensão social; (ii) questão financeira; (iii) mau comportamento dentro e fora de campo; (iv) bom comportamento dentro e fora de campo; (v) volta ao futebol brasileiro; (vi) saudade do Brasil; (vii) sonho a ser realizado. A análise de dados foi realizada à luz do referencial teórico apresentado no trabalho relacionando a fala dos jogadores com os pensamentos dos autores. Nota-se através da análise que não existe qualquer relação entre o comportamento dos jogadores de futebol entrevistados pela revista placar e o fato de eles serem oriundos de famílias humildes e que suas dificuldades de adaptação ao exterior estão relacionadas à falta de uma preparação física completa.
