Study of U Hla’s Experiences in Japan in 1936

In this paper, I focus on the characteristics of Japan and the Japanese people as portrayed in his writings by U Hla, a trader from Myanmar who studied the Japanese economy and industry, and the behaviour of the Japanese people during his visit to Japan in 1936. The aim of this paper is to know why U Hla wanted to visit Japan, what he learnt during his business trip to Japan, what kind of knowledge he acquired from Japan, why he was interested in the banking system, and how he applied the knowledge he gained in Japan after he returned to Myanmar. The primary and secondary sources for this study came from the National Library of Myanmar, Universities’Central Library, University of Yangon Library, University of Maubin Library, and Internet archives

Study of Galon U Saw’s Experiences in Japan in 1935

This paper deals mainly with the relations between Myanmar and Japan. In this study, a prominent figure from Myanmar politics who visited Japan and his endeavor to develop the relations between the two countries will be presented. At the beginning of the 20th century, the cordial relations between Myanmar and Japan did not exist. In 1907 Sayadaw U Ottama’s visit to Japan that the Myanmar began to take an interest in Japan. After Japan appeared as a modernized nation, the reform movements and achievements of Japanese was emulated by Myanmar. Likewise, it is assured that Myanmar nationals such as political leaders and entrepreneurs from all sectors have the desires to achieve as an Asian country like Japan. Therefore, how did the prominent figures from Myanmar nationals at that time study and observe about the achievements of Japan will be discussed in this paper. Moreover, the advantages of the Japanese developed achievement under observation and the some disadvantages of Myanmar under British administration and the necessary factors to make reforms will be researched. By conducting this research, it aimed to know not only the efforts to develop the Japan – Myanmar relations at present but also efforts to develop the relations in the past and it also aimed to observe costumes and traditions of both countries. The primary and secondary sources to write this paper was obtained from the National Library of Myanmar, Universities’Central Library, University of Yangon Library, University of Maubin Library and Internet Archive

Effect of tailwater depth and apron length on scour downstream of a weir

The study is carried out to research on the scouring downstream of an overflowing weir. The scouring is caused by the movement of sediments due to the impinging jet. The focus of the study is the equilibrium maximum scour depth as the depth of scouring could undermine the stability of hydraulic structures. To investigate the flow variables that affect the equilibrium scour condition, literature on the key concepts and previous studies investigating scouring phenomenon was reviewed. This is followed by running 25 experiments on a flume with the dimensions of 8.0m by 0.3m by 0.6m. The experiments were done in the laboratory and included a filming set-up to record the run across the full duration. Since the process of scouring was filmed, the relationship between scour depth and time was briefly discussed using the scour depth data from the video. The experiments were designed to investigate the effect of varying tail water depths and apron lengths on scouring across different flowrates, with all other variables kept the same. The results of the experiments reveal that the equilibrium scour condition is based on those three variables. The scour profiles of suitable runs are examined to compare between variations made in the flow conditions. It was found that the following flow conditions result in an increase in equilibrium maximum scour depth: increase in flowrate, decrease in tailwater depth and decrease in apron length. For runs without apron, an equation was established to predict the equilibrium maximum scour depth given the flow conditions. The prediction from the equation has an error range of ±30% , which is considered sufficiently reliable for future usage. For runs with apron, the correlation between apron length and scour depth was explored. The investigation established that the apron installed must be of a minimum length such that the apron can act as protection for the erodible bed. Below the minimum length, the impinging jet strikes the erodible bed instead of the apron, making the apron redundant. Additionally, the scour depth is lowered by 90% when the ratio of apron length to weir height tends to 3.5.Bachelor of Engineering (Civil
