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 interest to know about the use young people are giving to their Smartphone’s, leads us to analyze if the excessive use has generated some level of addiction in them. Moreover, we seek to identify if this behavior differs in relation to gender. The participants are high-school students enrolled at a public institution in the Port of Veracruz, Mexico. The sample was non-probabilistic since it was only authorized to survey those enrolled students who agreed to participate. A total of 164 students were surveyed. The SAS-SV scale designed by Kwon, Kim, Cho and Yang (2013) was used, which is made up by questions such as age and gender, as well as ten Likert-format questions. For its application, the survey was adapted to an electronic format (Google form) and delivered to all teachers, who in turn sent it to their students. Considering that it is a scaling instrument, it was necessary to use polychoric correlations matrices for the exploratory factor analysis as well as the ANOVA analysis. The main findings show three components: physiological, dependence and distraction, which explain 68% of the total variance. In addition, there is not gender differences were found.
Experiment investigation of twisted tapes insert have been performed for flat plate solar collector in laminar regime to study its effect on solar collector performance. Heat transfer rate and friction factor experiments were carried out with using twisted made from aluminum materials by using curvature vortex generators and fixed twist ratio(Y=2). Twisted tapes insertion was, typical twisted tape (TT), twisted tape with curved vortex generation in facing flow (TTFF). In order to expand the experimental range, the solar collector was tested at four different values of mass flow rate, from 0.025kg/s to 0.117kg/s. at Reynolds number Re from 400 to 2000. The results obtained were compared with those obtained from plain tube published data the results clearly indicate the enhancement of the Nusselt number by insert device. The results show that the Nusselt increasing with (31.4%-54%) by using twisted tape with curvature vortex generator (TTFF)
