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.

In order to measure the concentration of natural radionuclides in soil . The gamma spectrometric method (using 2.5 3.8 cm NaI(Tl) detector) was performed on soil samples .These samples were taken from different soil sites of Ancient Mosul in Mosul City, North of Iraq. Thirty Four soil samples were measured in order to assist specific activities of radionuclides of Ra-226 , Th-232 and K-40 . All of these samples were collected randomly from a depth of about 20cm from the surface using a hand trowel .Then soil samples were dried , crashed and passed through sieve. After that all the samples stored for one month. Before the analysis of soil samples , energy and efficiency calibration were carried out .We analyzed the spectra of samples using multi-channel analyzer (MCA) connected with the measurement system . The results of specific activities of radionuclides Ra-226,Th-232,and K-40 varied from 6.20 to 26.51(Bq/Kg) with A mean value 11.05( Bq/Kg) for Ra-226, 11.33Bq/kg to 40.78(Bq/kg) with A mean value 23.93(Bq/kg) for Th-232 and varied from 82.88 to 482.45(Bq/kg) with A mean value 226.60(Bq/kg) for K-40. Moreover, the results of this study were compared with those reported from other countries and worldwide average
During development and analysis of electrical machines, the electromagnetic field simulation software is used to their design and performance study. Ansys Maxwell, transient solver, is related with serial solution steps to determine machine currents, slot orifice width effect, material saturation and instantaneous rotor position. In this paper, Ansys Maxwell software is employed to design the Linear Induction Motor (LIM) using four types of slot orifice width. Flux density in the air gap with its harmonic analyzed by Fast Fourier Transform (FFT) are simulated. The performance of the mentioned LIM is investigated and compared with each other for the types used, which include the three –phase stator current and force develop
