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 aim of this work is to thermally characterize waste coffee grounds produced each year in the world in significant quantities in the soluble coffee industry and in the preparation of domestic and commercial drinks. This article presents an experimental study to determine the thermal behavior of coffee grounds powder in Morocco by: thermogravimetric analysis, differential thermal analysis and differential scanning calorimetry, in an oxidizing atmosphere and with a heating rate at 20 ° C / min. The apparent activation energy of the combustion of the main volatiles was determined using the Coats-Redfern method. The apparent activation energy was 20.997 kJ • mol-1, 26.114 kJ • mol-1 and 30.478 kJ • mol-1, respectively
Earth is a natural and multipurpose material, used since ancient times in construction, especially in developing countries. In this work we chose adobe block as an example of the earth material used in construction, mixed it with some fibers stabilizers like straw fibers and pine needle fibers in different rates separately. We have selected the soil from Had Laghoualem, KHEMISSET for making the samples of adobe blocks. The objectives of this work are: study of the mineralogical characterization of the soil and the fibers stabilizers,that we were used for making the samples, it carried out by several techniques (X-ray diffraction, infrared spectroscopy). The results show that each of these materials consists of carbonates calcite, kaoliniteand quartz. Also, we made the samples of adobe blocks stabilized by fibers and measured their thermal conductivity. The thermal results show that the thermal conductivity of the adobe blocks samples is inversely proportional with the rates of straw fibers stabilizers, and pine needle fibers stabilizers. The CT-METRE device was used for measure thermal conductivity
