Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Waste management is an important issue form Morocco. According to many possibilities, recycling construction and demolition wastes (CDW) as aggregates replacing naturel aggregate for concrete is a solution that deserves to be evaluated. In this study three sample of concrete are tested. 2 with different percentages of recycled aggregates Their properties are compared to the concrete with natural aggregates. Concrete is realized and tested in thermal conductivity (cylindrical 5x3.23 specimens). With quantity of recycled aggregates is (0 %, 10 %, 20 %) in different temperature (20°. 30°.40°.50°C). Numerical modeling with FORTRAN program was proposed for comparing between experimental and numerical results. It is shown that the use of recycled aggregate as replacement for natural aggregate in concrete decreases the thermal conductivity. we also see that the value of the thermal conductivity decrease with the increase of the temperature of the ambient air 20 degrees up to 50 degrees for the 3 samples Normal concrete and concrete with recycled aggregate. For the three samples the numerical and experimental results were in good agreement. The following conclusions can be drawn from this work: that according to the thermal properties, the recycled aggregate concrete possible to be used in the same applications as conventional concrete
This work concerns a mathematical modeling and a numerical simulation of the transesterification reaction of lipids extracted from micro-algae by biodiesel. We have developed a numerical model to simulate the consumption of reagents, the evolution of reaction intermediates and the formation of products. The model is based on the Euler and Runge-Kutta methods. The system of equation established from the different reactions that take place during the trans-esterification has been solved using a numerical code written in FORTRAN. The simulation gives the evolution of the relative concentrations of reactants, intermediates and products of the reaction as a function of time. The duration of reagent consumption and product formation reactions is shorter when equation resolution is done by the Runge-Kutta method. The results obtained by the latter are close to those of the literature
