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.

This study is about the mandibular fractures in Baghdad the capital of Iraq. The epidemiology and outcomes of mandibular fractures in one of the maxillofacial departments in Baghdad had characterized in this study. The goal of this study was to classify mandibular fractures into relation to fracture age, gender and anatomical position. The study population considered 829 cases of fracture mandible in 585male and 244 females. In this file, age and gender have registered. The patient records in the Maxillofacial Department at Al-kindy Hospital in Baghdad were review and retrospectively analyze from the beginning of 2015 to the end of 2019. The p-value was found to be less than 0.05 and p < 0.001 to be highly important. They manifested that the major group of patients age was the group between 18-45 year of age for N=668 which comprises 80.58% and the age ≤ 45 year (10.62% = 88 case). Of all cases, the age group1-18 year was only 8.81% = 73 case. All these cases were different in type and severity of fractures. Mandibular fractures are very common in Iraq, with the highest rates involved in assaults, and the second cause is the RTA and the fall.
Speed control of a series excited d.c motor is primarily achieved through a regulated flux in the field winding. A well-adjusted flux is considered very effective in voltage and speed regulation. This process can be achieved through a field and armature current adjustment using a shunt diverter resistance. Tapped field control and parallel field coils also serve as a veritable measure for the speed control of a dc series motor. Although this method is scarcely used for the speed control of dc series motor. This paper is aimed at investigating the effect of applying a diverter resistance with well-adjusted thyristor firing angles for a controlled rectifier on dc series motor speed control. In this study, the steady state and the dynamic state equations that correlate the speed of dc series motor with diverter resistance and supplied voltage as a function of a thyristor firing angles were derived. Speed characteristics based on the derived equations were determined through simulation in MATLAB 7.14 for different values of diverter resistance and thyristor firing angles under a varying machine load. The simulation results showed that the series dc motor runs at a very high speed above the rated value in the reverse braking mode by increasing the thyristor firing angle beyond 900. Adjusting the firing angle below 900, speed values below the rated speed were obtained as the load current is increased in the forward motoring mode. A proper adjustment of the firing angle regulates the supply voltage as well as the high starting current.
