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.

This study of Protozoa has been carried out at three investigated sites on the Euphrates River. Samples of water and Protozoa were collected monthly for the period from April 2017 to November 2017. Some chemical and physical factors of water were studied and the results showed that the water temperature was ranged from 17 to 35 °C, Total Dissolved Solids (TDS) ranged from 400 to 779 mg.l-¹, turbidity ranged from 2-7 NTU, Magnesium (Mg2+) ranged from 50 to 299 mg .l-¹, and Chloride (Cl-2) were ranged from 100 to 203 mg.l-¹ while Sodium ranged from 44-87 mg.l-¹. Concerning the Protozoa, 25 taxa were identified which belonged to two Classes: Ciliata and Sarcodina. According to the Shanon-Weiner index, species diversity for Protozoa were ranged from 0 to 0,9 bits/individual. Jaccard’s similarity index among months showed that the highest similarity was recorded between April and June with 0.83 %
This paper presents the development of concrete thermal behavioral through recycled aggregate from demolition and construction waste composed from numerous places. By means of thermal conductivity test, a total of more than 15 concrete mixes were examined to provide enough data tables and curves. Numerous chemical and physical test of aggregate composition from recycled and natural concrete is used to investigate the new production characteristics. Afterward, to assess the thermal behavior of the mix, many tests were carrying out the results on fresh and hardened states. The examination of thermal behavior illustrate that the employment of recycle aggregate improve the thermal behavioral of concrete mixes. The change amount showed quite variation depends on the originality of recycle aggregate used in this experiment. The resulting treatment shows that the hard bitten concrete could be compressed and recycled as coarse aggregate in new concrete construction which provides practical types of green concrete
