1. Degradation of textile dyes by cyanobacteria
Abstract Dyes are recalcitrant compounds that resist conventional biological treatments. The degradation of three textile dyes (Indigo, RBBR and Sulphur Black), and the dye-containing liquid effluent and solid waste from the Municipal Treatment Station, Americana, São Paulo, Brazil, by the cyanobacteria Anabaena flos-aquae UTCC64, Phormidium autumnale UTEX1

2. Atmospheric corrosion of Nylon 6,6 in Mauritius
ABSTRACT Plastics are being more and more commonly used for outdoor applications in Mauritius. In this context, the atmospheric corrosion degradation behaviour of nylon 6,6 was observed in the Mauritian atmosphere, having a corrosivity category of C3, according to ISO 9223. The crack width, depth and extent of the cracks formed on the surface were investigat

3. Heterogeneous fenton process using the mineral hematite for the discolouration of a reactive dye solution
This work reports a study on the heterogeneous Fenton reaction using hematite powder (Fe2O3) in suspension for the discolouration of the reactive dye Drimarene Red X-6BN in aqueous solutions. The efficiency of the process was studied as a function of the experimental conditions: initial pH; H2O2 dose; and hematite powder concentration; all of which showed a

4. Desenvolvimento de membranas com lacases por imobilização do extrato enzimático de Pleurotus sajor-caju
As lacases (EC 1.10.3.2) são fenol-oxidases associadas à habilidade de degradar a lignina e outros compostos recalcitrantes, como xenobióticos e vários tipos de corantes sintéticos. Lacases catalisam a oxidação de vários compostos aromáticos com concomitante redução do oxigênio a água. Neste trabalho são apresentados os resultados de imobiliza�

5. Familial dentinogenesis imperfecta, blue sclerae, and wormian bones without fractures: another type of osteogenesis imperfecta?
A unique connective tissue disorder characterised by the triad of dentinogenesis imperfecta, blue sclerae, and multiple wormian bones has been identified in 20 members of three generations of a large kindred of mixed ancestry in South Africa. The skeletons of affected subjects were moderately osteoporotic but, apart from minimal bowing of the femora and some

6. Oguchi disease: suggestion of linkage to markers on chromosome 2q.
Oguchi disease is a rare autosomal recessive form of congenital stationary night blindness. The condition is associated with fundus discolouration and abnormally slow dark adaptation. Earlier studies suggested that the 48 kD protein S antigen may be involved in the recovery phase of light transduction. Previous cytogenetic and linkage studies have localised
