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 research of renewal energetics resource has increased substantially in the last decades, the oil reserves are not enough, and the pollution generate since at the fossil fuels burn has alert to industrialized countries on the development of alternative fuels. Colombia is not indifferent to this situation and has found on the natural gas a transition fuel before of massive implementation of biofuels. Conversions of gasoline engines to natural gas (NG) have entrance massively on the vehicle park of the country since facilities on availability of fuel, prize respect to gasoline, and technical support. However, a lot of dismount of equipment is occasioned because the mixer does not accomplish with the proper design for each engine type. This research paper is evaluated the fluid-dynamic behavior of an Air/Natural Gas mixer employing computational fluids dynamics (CFD) to find the constructive parameters that generate the most homogeneous mix in the entrance to intake manifold of a Mazda 323NX engine. An experimental design was made to do the simulations where the factors and their levels are calculated by the Mitzlaff and Agudelo Methodologies. In concluding this research is found that the Agudelo methodology with a venture diameter of 54 mm and gas outlet in groove form generates a 93% of the homogeneous mixer
There is a strong need for improvement of vital information on perinatal health due to high rate of anomalies such as stillbirths especially in low and middle-income countries to ensure normal and safe delivery as well as healthy baby after birth. The fetal heart rate (FHR) monitoring is an important tool for trucking the fetal health condition during pregnancy based on parameters such electrical signals, magnetic fields and acoustic vibrations which consequently enable early detection and diagnosis of fetal heart abnormalities. Various Electronic Fetal Monitoring (EFM) techniques have been used during pregnancy and delivery to ensure the fetal heart grows and functions properly. Of them, the fetal Phonocardiography (fPCG), the modern form of auscultation, is a graphical recording of fetal heart sounds (FHS) acquired from the mother’s abdomen surface. In contrast to other techniques, fPCG is safer for repetitive and long-term application which is highly recommended for high risk pregnancies. In this paper, various fPCG sensors were reviewed and compared with a purpose of developing a convenient, cost-effective, and reliable home based FHR monitoring device. The review concluded that electret microphone PUM-5250R-L model is recommended for its high sensitivity and SNR. Therefore, it will be used to develop the proposed device to acquire and measure FHS physiological parameters non-inversely
