    Automotive Industry and Trend Analysis in Ethiopia
    (Addis Ababa University, 2007-07) Desta, Eskinder; Belwal, Rakesh (PhD)
    The main purpose of the research was to analyze the automotive industry and its trend in Ethiopia. In recent years, the contribution of the automotive sector is increasing and it is playing important role in the national economy. Although the automotive sector is playing significant role, it is still at low level and many factors contributed for that, including: • Government regulations • Road conditions • Purchasing power of the people • Lack of skilled manpower and capacity • Shortage of capital To address those issues, the researcher used both primary and secondary data. The collected data were analyzed and the result of the analysis was summarized in to positive and negative aspects. It was revealed that the positive aspects; contribution to the national economy, future growth prospect, employment opportunity and profitability of the operation outweigh the negative aspects. As the research had scope and limitations, it was recommended to the governing authorities to undertake further studies to make an informed decision on how to support the growth and development of the automotive industry in Ethiopia.

    Investigation of the Binding Materials Properties and Assessment of Durability Issue in Fasil Ghibbi Palace in Gondar
    (Addis Ababa University, 2015-08) Desta, Eskinder; Dinku, Abebe(Professor)
    Historical monuments are the precious signs of our past. They are non-replaceable fragments of our cultural heritage and their future depends on our attitudes and actions towards preserving them. Attitudes are undoubtedly changing in the ways we view our cultural heritage and people are becoming more conscious of the unity of human values and regard ancient monuments as a common heritage. Conservation of ancient monuments is a process which will lead to the prolongation of the life of cultural property for its utilization now and in the future. But, before practicing conservation, one must have a broad understanding of the field itself. This is of course to ensure that any action carried out during the conservation work is properly performed and is in accord, not only with the building requirements, but is within the scope of contemporary knowledge of the subject. The appropriate selection of the binding materials during the construction of stone bridges, palaces, churches, cathedrals restoration, and conservation of historical monuments is essential at the time of intervention. Today, these historical structures are in different physical state, some are in relatively good condition, while many are in a deplorable state. The purpose of this study is to identify the method of construction and analyze the construction materials which were used in Royal palace construction in order to define their characteristic properties, durability and to consider the properties of original materials, thus enlightening the usability of them in repair of such buildings. For this purpose, samples of the construction materials like binding mortar, which were used in Fasil Ghibe Palace construction, were taken and Extracted in Ethiopian Geological Survey Laboratory. The type of binding material which was used during the construction of the Fasil Ghibbi palace is identified as Lime (CaO) or by its local name Nora. And also the method of construction was by stone masonry. The major cause of deterioration of the Royal Palace is due to various reasons, some of which are long life, lack of periodic maintenance, unchecked growth of trees, grass, algae & mechanical impact on the wall surface by Visitors.
