Models used for materials evaluation

Treating dredged sediment is a complex processing and ongoing challenge. To utilize dredged sediment for the landfill or construction purposes, a material fabricated from a mixture of dredged sediment, Portland cement, and fly ash, was cured under room temperature and hydrothermal condition at 180 °C and 0.9 MPa pressure for 16 hours. The response surface methodology was used to evaluate the compressive strength of the material, with the range of factors investigated being the dredged sediments/solid ratio (0.3 - 0.9), cement/fly ash ratio (2 - 4), and water/solid ratio (0.45 - 0.55).

The specific research objectives of this study are: 1. The development of a high throughput method for evaluation of alloys (5xxx Al as model materials in this work) subject to pitting; 2. Understanding the roles of variation in functional groups' in determining the inhibition efficiency; 3. Elucidating the inhibition mechanisms; and 4. Unveiling the role of intermetallic present in Al matrix and their contribution to the inhibition mechanism, particularly the long-term durability of the inhibitor systems.

The study aims at evaluating the textbook Tiếng Anh 6 (10-year program) to explore if it really meets the defined aims of the course and if it is appropriate to the students’ level of English and their background knowledge. I also hope that the findings of the thesis will partly help to decide whether to modify any contents or the structure of the book to improve the quality and the effectiveness of the material.
