1. Microstructural and mechanical characterisation of the Simon Bolivar's iron bridge structure, 19th century, Arequipa, Peru
Abstract The microstructure of the main structural elements (Phoenix columns, transversal beams and tie-rods) of the Simón Bolivar iron bridge, located in Arequipa (Peru), was investigated. The bridge was supposedly designed by Gustave Eiffel and opened to the public in 1882. The characterisation revealed that the columns, beams and tie-rods are made of pud

2. Assessment of quality attributes of tomato sauce supplemented with moringa root
Abstract This study was conducted to evaluate the quality and mineral contents of Moringa oleifera root-based tomato sauce. Results showed that roots of M. oleifera are highly enriched with essential nutrients including minerals, such as iron, sodium, magnesium, calcium, potassium and zinc and vitamins specifically vitamin C. Thus, it is useful as a nutritio

3. Physicochemical and microbiological stability of fermented dairy beverages added with red rice extract
Abstract Fermented dairy beverages added with red rice extract and whey were the developed, physicochemical and microbiological properties were evaluated. A central composite rotatable design was applied, using nine treatments with three replicates. The pH indicated that the beverages could be consumed without the addition of preservative for up to 28 days o

4. Comparative analysis of citrus fruits for nutraceutical properties
Abstract Fruits and vegetables (F and V) are valuable for their micronutrients, but many F and V in diverse growth areas have not been scientifically validated for these components. The nutraceutical characteristics of the pulp of eight citrus fruits grown in Pakistan were, therefore, investigated. Expectedly, the fruits differed in moisture (86.9-88.9%), as

8. Evaluation of arugula cultivars and seed production in the organic system
Resumo: A produção de rúcula (Eruca sativa Mill.) no Brasil utiliza sementes produzidas pelo sistema convencional, não tendo disponibilidade de sementes orgânicas. O objetivo deste trabalho foi indicar as cultivares de rúcula de melhor desempenho durante a fase de produto comercial e avaliar a viabilidade da produção de sementes, assim como a germina

9. Production and Nutrient Accumulation of Common Bean Cultivars under Competition with Weed
RESUMO: O manejo inadequado das plantas daninhas é uma das causas da baixa produtividade do feijoeiro, pois ele é muito suscetível à interferência delas, devido ao seu crescimento inicial lento. Objetivou-se com este trabalho avaliar a influência da trapoeraba na produção de grãos e acúmulo de nutrientes de cultivares de feijoeiro. O experimento fo

10. Análises de dosagens de concreto asfáltico do tipo Pré Misturado a Frio (PMF) utilizando Resíduos da Construção e Demolição de obras (RCD)
RESUMO Na construção civil, um problema ambiental recorrente é a geração e disposição de Resíduos de Construção e Demolição (RCD) de obras. A utilização do RCD como agregados na composição de concreto asfáltico, do tipo Pré Misturado a Frio (PMF), torna possível a execução de pavimentos rodoviários de baixo tráfego. Diante desses fatos

11. Degradation of Acid Red 8 Dye Using Photo-Fenton Reaction Mediated by Titanium Modified Catalysts
Catalysts prepared by co-precipitation of iron and titanium were evaluated in heterogeneous photo-Fenton degradation of the azo dye Acid Red 8 under blacklight irradiation. Materials with different titanium contents (0 < Ti/Fe < 0.6) were characterized using X-ray diffractometry, scanning electron microscopy, X-ray fluorescence spectroscopy, specific surface
