1. Consortium of Microalgae for Tannery Effluent Treatment
Abstract Wastewater generated in tanneries have essential elements for microalgae growth, but it has also some toxic compounds that may hinder or restrain the growth of microalgae in this environment. This work tested microalgae consortium growth originating from a deactivated effluent treatment decanter of a complete tannery (beamhouse to finished leather)

2. Resíduo de Curtumes como Fonte de Nitrogênio para Trigo e Arroz em Sucessão
RESUMO O processo de estabilização necessário para o curtimento das peles, na indústria coureira, gera grande quantidade de resíduo sólido colagênico com elevado potencial poluidor. Esse resíduo contém elevado teor de nitrogênio, o que confere ao resíduo potencial para uso agrícola. Para avaliar a viabilidade da aplicação de rejeito da indústr

4. Extraction of Indigo from Some Isatis species and Dyeing Standardization Using Low-technology Methods
Fresh leaves of four Isatis species culture form of I. tinctoria L and wild forms of I. buschiana Schischkin, I. candolleana Boiss. (endemic) and I. tinctoria L. subsp. corymbosa. (Boiss.) were used for indigo production. Dyes were extracted by fermentation and hot water application. The extracted dyes were optimized with different pH and reducing agents. Re

5. Potential of wet blue leather waste for ruminant feeding
The objective of this study was to find an alternative to minimize environmental contamination by leather waste using it as ruminant feed. The wet blue leather wastes (WB) without chrome extraction were compared with the leather wastes in which the chrome was extracted (CE). Both materials had 99.7% of dry matter (DM), but the crude protein level was higher

6. Influência dos processos de engraxe e acabamento na modificação da estrutura e nas propriedades do couro
O estudo do colagênio na pele sobre sua estrutura e propriedades, composição e interações com substâncias levam a um maior entendimento das alterações químicas, micro e macroscópicas que ocorrem durante o processo de produção do couro. No processamento do couro são realizadas várias etapas que promovem a alteração da estrutura dérmica da pel

7. Curtain color and lighting program in broiler production: III - thermal comfort
The objective of this study was to evaluate the thermal comfort of broilers reared under two lighting programs (almost continuous and intermittent) in broiler houses with yellow or blue lateral curtains. The experiment was carried out from June 24, 2004 until May 12, 2005. Six consecutive flocks were housed in four 12 × 10 m broilers houses internally divid

8. Butea frondosa as a gastro protective against induced gastric lesions
The study was undertaken to evaluate the potential of alcoholic extract of Butea frondosa Koen. ex Roxb against gastric lesions induced in rats using acetic acid plus pyloric ligation. The impact of alcoholic extract of Butea frondosa in doses of 100, 200 and 400 mg/kg as single dose schedules and 200 mg/kg for 7, 14, 21 and 28 days was determined. Parameter

9. The influence of Chromium supplied by tanning and wet finishing processes on the formation of cr(vi) in leather
Chromium used in leather manufacturing can be oxidized from the trivalent to the hexavalent state, causing environmental concerns. In this study, the influence of Cr(III) from tanning, deacidification pH, fatliquors, chrome retanning and vegetable retanning on the formation of Cr(VI) in leather was analyzed by comparing natural and aged samples. In wet-blue

10. C-phycocyanin extraction from Spirulina platensis wet biomass
C-Phycocyanin is a natural blue dye used in food and pharmaceutical industry. In the present study, a simple and efficient method to extract C-phycocyanin from Spirulina platensis wet biomass is reported. The extractions were carried out using six different methods, including chemical (organic and inorganic acid treatment), physical (freezing and thawing, so

11. A comparative analysis of attribute reduction algorithms applied to wet-blue leather defects classification.
This paper presents an attribute reduction comparative study on four linear discriminant analysis techniques: FisherFace, CLDA, DLDA and YLDA. The attribute reduction has been applied to the problem of leather defect c1assification using four different c1assifiers: C4.5, KNN, Naive Bayes and Support Veetor Machines. Results and analyses on the performance of
