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.
Technology Reports of Kansai University (ISSN: 04532198) is a peer-reviewed journal. The journal covers all sort of engineering topic as well as mathematics and physics. the journal's scopes are
in the following fields but not limited to:
The average concentration of trace metals namely; Cd, Co, Cr and Fe in edible vegetables and soil samples collected randomly in Bekwarra Urban Area of Cross River State were determined using flame Atomic Absorption Spectrometer (AAS). The Target Hazard Quotient (THQ) was also calculated based on the amount of the metals in the vegetables to evaluate the possible health risk associated with the consumption of the vegetables. The eight vegetables considered together with the soil samples where they were planted include: Amarathus spp., Corchorus olitorius, Murraya koenijii, Ocimium grattissimum, Solanum melongena, Talinum triangulare, Telfaira occidentalis and Vernonia amygdalina. These values revealed that the average concentration of Cr and Fe in mgkg-1 in the soil ranged between (0.058-0.068) and (0.009-0.043) respectively in the rainy season, and (0.051-0.061) and (0.008-0.038) respectively in dry season. The mean concentration of Cr and Fe accumulated by the vegetables in mgkg-1 was in the range 0.015-0.048 and 0.005-0.027 respectively in rainy season and 0.013-0.047 and 0.004-0.025 respectively in dry season. Cd and Co were string variables as their concentration was not detected in the soil or vegetables. The Target Hazard Quotient (THQ) values of Cr and Fe for all the vegetables were less than 1 implying that there is no health risk associated with the consumption of the vegetables at the time of this study. The values also reveal that there is some level of trace metals pollution of the area and the vegetables, though very low and within the permissible limits of WHO/FAO
Wireless Sensor Network (WSN) is one of telecommunication technology aim to reduce the infrastructure cost by using node to node communication. A Fuzzy TOPSIS is proposed for routing algorithm to automatically select another nodal for communication channel hopping, and thus provide better QOS for wireless sensor network. From our simulation Fuzzy Topsis algorithm compare with star topology has benefit which is lower delay (2/3 better) and better packet loss (4/5 better) but at higher cost which is more hopping for communication channel (5/3 hopping)
