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.

The paper presents the results of the study examining morphological features of root system and their connection with herbage in different alfalfa genotypes, represented by the following varieties and populations: Louise, Zoryana, Nadezhda, Unitro, Seraphim, RK/98, PR-04, MO-115, SV, HMG. The study was conducted within 2015-2018 in the field conditions at the Institute of Irrigated Agriculture of NAAS at the dark-chestnut soil. The crop cultivation technology was standard for the irrigated conditions of the zone of the study conduction. The experimental data were processed by the generally accepted procedure of the analysis of variance and Pearson’s correlation analysis. The results of the study testify about the significant differences in root system morphology in different genotypes of alfalfa, and their unequal value for plant breeding work. The varieties Zoryana, Seraphim and the population MO-115 with a high volume of the root system of 6.9-7.0 milliliters and the established links between the studied features of subsurface and herbage biomass are recommended to be used in further alfalfa breeding work
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
