Biorremoção de corante direto de efluente industrial simulado utilizando levedura liofilizada

One of the most primal ways of human work already known is the tessellation and ginning for the production of fabric and clothing - what used to be, back in those days, statement of power and status. The arrival of the Industrial Revolution - in the middle of the XVIII century at Britain - increased the textile industry production, and what used to be manufactured and hard to obtain, starts then to be produced in mechanical ways and large-scale. Despite all the boost given to the economy of an expanding capitalist market, it should be pointed out the consequences of this major industrialization, especially the environmental ones, more and more concerning nowadays. The emissions of waste - that sometimes could be toxic - in effluents can possibly contaminate the aquatic ecosystems, causing a huge damage to its fauna and flora, affecting therefore all the biodiversity, reaching inclusively the humans. To avoid these problems, a few strategies have been taking place in the attempt to eliminate - or at least reduce - the amount of dye found in the effluents, and as the textile industry constantly leaves waste, efficient methods - that present good results in a short period of time - with a low cost are needed. The present study will test the bioremoval capacity of yeast (Saccharomyces cerevisiae) in contact with dyes in a fix concentration, diluted in water with three different pH values. The tests will be done duplicate, and after the concentration analyses - made by spectrophotometry - it will be analyzed which pH shows major efficiency in the dye removal and what is the influence of the biomass in this process

Modificação de amido de mandioca com peróxido de hidrogênio e ácido lático em diferentes processos de secagem

The oxidized cassava starch is widely used in various industrial sectors, the major textile, paper and more recently by the food industry due to its characteristics, such as expansion property to baking. This study aimed to develop a modification of cassava starch by reaction with hydrogen peroxide and lactic acid, with two different types of drying, in the sun and in oven dried, in order to develop the expansion with increase of carboxyl groups and to evaluate differences between the types of drying and compare them with Expandex® starch and pre-gelatinized. The results indicated an increase in the rate of expansion of the modified starch dry in the sun, however the results of the content carboxylic groups haven't indicated the relationship with their rate expansion.

Estratégias construtivas para a configuração do produto de moda

This article approaches possibilities and strategies of building to development of fashion product. It investigates the application of different constructive resources of textile materials of same composition and trim, establishing for this parameters of formal similarity. The conception of products process is conducted by three-dimensional expression, which allows the steps for creating and delivering happen simultaneously. Three-dimensional modeling techniques enable the buildings that are structured by the following features investigated: intervention in the textile surface, insertion of independent elements, and different confection resolutions. The results instigate reflection about the processes involved.

Efficiency in Brazil's industrial sectors in terms of energy and sustainable development

This article evaluates the efficiency of Brazil's industrial sectors from 1996 to 2009, taking into account energy consumption and respective contributions to the country's economic and social aspects. This analysis used a mathematical programming method called Data Envelopment Analysis (DEA), which enabled, from the SBM model and the window analysis, to evaluate the ability of industries to reduce energy consumption and fossil-fuel CO2 emissions (inputs), as well as to increase the Gross Domestic Product (GDP) by sectors, the persons employed and personnel expenses (outputs). The results of this study indicated that the Textile sector is the most efficient industrial sector in Brazil, according to the variables used, followed by these sectors: Foods and Beverages, Chemical, Mining, Paper and Pulp, Nonmetallic and Metallurgical.

Estudo da utilização de serragem de madeira como adsorvente para o tratamento de efluentes têxteis

The Brazilian textile industry has been a highlight in the global economy. Connected with this high economic performance there is the water consumption and the generation of great volumes of wastewater which present high concentrations of dyes and chemical substances. One of the main techniques used in the treatment of textile effluents is adsorption, which has the activated carbon as the main adsorbent. Recently, studies have been developed to find alternative materials to activated carbon and exhibiting good adsorption capacity of dyes. The aim of this work is to study the potential of sawdust as adsorbent of low cost to remove the dye Direct Green 26. The results of this type of dye removal were obtained through the study of adsorption isotherms obtained by spectrophotometry in the UV-visible region analyzed by the Langmuir model. Finally, a comparison was made of these results with those of other adsorbents. Results showed that the average removal of dye, using sawdust, was 78.8% for an initial concentration of 500mg / L and the maximum adsorption capacity of 119mg / g. These results demonstrate the great potential of sawdust as an adsorbent for the dye Direct Green 26.

Mary E. Frayser Papers - Accession 1

The Mary E. Frayser Papers consists of correspondence, speeches, reports, clippings, minutes, histories, family histories, constitutions and bylaws, membership lists, program notes, photographs, and other papers, relating to her work with the South Carolina Extension Service (1912-1940) Winthrop College, her involvement with the South Carolina Council for the Common Good (1935-1952), the South Carolina Federation of Women’s Clubs (1926-1952), the South Carolina Status of Women Conference (1945-1952), the South Carolina Division of the American Association of University Women (AAUW) (1929, 1935-1949), the South Carolina Interracial Institute (1938-1942), the South Carolina Division of the Southern Regional Council (1944-1951), and the South Carolina Conference of Social Work (1936-1967). There are also papers relating to Frayser’s efforts to promote social and economic legislation and participation by women in public affairs and her interest in libraries and work in the movement for the support of public libraries in South Carolina (1925-1968). Correspondents included G.H. Aault, Evan Chesterman, Wil Lou Gray, Sarah Hughes, Christine South Gee, and Maude Massey Rogers. This collection is a good source of women’s club activities in the twentieth century. Important areas of research would include the way club activity affected social and economic legislation in the state and the various forces involved in the movement for state tax supported libraries. While the papers do range from 1841 to 1953, the greater bulk of the papers extend from the early 1930s to about 1947. Since the work of the various women's club organizations were so inter-related, a researcher working with the papers of a particular organization for a particular time span should consider the Frayser papers of all other organizations. The related papers for the “Correspondence and Related Papers” series for particular organizations are generally similar and include: memoranda, outlines, reports, resolutions, minutes, etc. Additional Frayser information can be found by referring to the Winthrop University Archives (official records).
