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.

Experimental investigations of solar desalination unit based on humidification and dehumidification processes are presented in this work. The test rig is designed, constructed, and tested. The experiments were tested at Baghdad University, college of engineering, Mechanical engineering department (33.3° latitude north, 44.36° Longitude East). The effects of Linear Fresnel Lenses have been studied in this work. Different cases are investigated such that: they were placed on the 3rd and 4th absorbers of the PTC, they were placed on the humidifier chamber and they were placed on the 2nd and 3rd absorbers of the PTC. when lenses were placed on the humidifier to concentrate solar energy on the transparent glass cover the absorber surface temperature was increased by 8.2 % at 14:00 pm, the inlet temperature of the oil was increased by 7.1 % while the outlet oil temperature was increased by 14 % and water production is increased as (31.2 %) at 14:00 pm is higher than that when these lenses were placed on absorbers
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 %
