    On the Combination of Silica Fume and Ceramic Waste for the Sustainable Production of Mortar

    Zine El Abidine Rahmouni1,*, Mekki Maza1, Nadia Tebbal2, Messaouda Belouadah1

    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.5, pp. 1083-1090, 2023, DOI:10.32604/fdmp.2022.021970

    Abstract The combined use of silica fume (SF) and ceramic waste (CW) for the production of mortar is studied. Sand is replaced by 5%, 10%, 15% and 20% of CW while a fixed 5% percentage (% wt of cement) of SF is used. The results show that the best results are obtained by using silica fume and ceramic waste sand with 15% weight of sand and 5% wt of cement. With the addition of sand ceramic waste (SCW), the mortar compressive strength and density increase, while the porosity displays an opposite trend. The experimental analysis is complemented with theoretical considerations on… More > Graphic Abstract

    Opportunities and Challenges of Plant Bioactive Compounds for Food and Agricultural-Related Areas

    Maicon S. N. dos Santos1, João H. C. Wancura2, Carolina E. D. Oro3, Rogério M. Dallago3, Marcus V. Tres1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.6, pp. 1105-1127, 2022, DOI:10.32604/phyton.2022.020913

    Abstract The growing development of biological products highlights the social and environmental responsibility that several industrial companies are facing in recent years. In this context, the advancement of bioprocessing as an alternative for exploring the potential of ecologically based products, especially in biofuels, food, and agro-industrial business, exposes the rational efficiency of the application of renewable sources in different industrial segments. Industries strongly associated with food production concentrate large amounts of wastes rich in bioactive compounds. A range of highly effective technologies has been highly explored to recover large concentrations of prominent compounds present in these materials. The advances in this… More >

    Yield and quality of tomato with organic sources of fertilization under greenhouse conditions

    Márquez-Hernández C1, P Cano-Ríos2, U Figueroa-Viramontes3, JA Avila-Diaz4, N Rodríguez-Dimas2, JL García-Hernández1

    Phyton-International Journal of Experimental Botany, Vol.82, pp. 55-61, 2013, DOI:10.32604/phyton.2013.82.055

    Abstract The scarcity of fertilizers that are allowed in organic agriculture (AO) encourages the search for alternatives, being the use of compost one of the most outstanding. AO has been recognized as a more sustainable system than conventional agriculture. AO is ruled by strict norms which forbid the use of most common fertilizers. The aim of this study was to evaluate the effect of various fertilization treatments on the organic production of greenhousegrown tomato. A completely randomized experimental design with five replications was used, with a 5x2 factorial arrangement. Factors A and B were: a) fertilization treatments and b) tomato genotypes.… More >
