The participants, a small group of technical writing students, engaged in writing a proposal targeting a real-life local problem as well as finding a solution. The study shows that authentic learning, such as writing the proposal for a real-world problem, can generate a potential solution while the service learning portion of the assignment （such as working with the community） can provide a specific real-life location for resolving the problem. The study also shows that the authentic learning experience can inspire the students to move further to serve the community and when students volunteer to help the local community implement the solution, a bridge between the authentic learning and service learning can be built, which can then lead to students＇ enhancement of all round real-life skills and of a sense of serving the community. Finally, the implications of the study for English language teaching in an authentic leaming context also will be discussed.展开更多

In earlier situations for these types of cases conventional method of repair and rehabilitation has been used. These innovative approaches for restoration have led to enormous saving of cost and time. The advantages of post tensioning are well known in the civil industry and are being used for the last 40 to 50 years. Post tensioning is one of the best methods to induce stresses in the concrete before application of live load and this technique can also be widely used for restoration and rehabilitation of structures. Unlike the use of post-tensioning in new structures there are no definite methods or codes for application in restoration and rehabilitation of structures. For restoration and rehabilitation of structures, PT （post tensioned） technique can be applied in combination with other techniques and materials available. Bridge lifting is a tricky and risky job especially when the superstructure is displaced appreciably by a natural calamity, etc.. Not only the present state of structure needs proper study before commencement of restoration and rehabilitation but also calls for careful execution. This paper deals with case studies of innovative applications of post tensioning in restoration and rehabilitation of structures and restoration of bridge structure in Andaman ＆ Nicobar Island, India affected by Sumatra quake.展开更多

In general, that is only possible through engineering geological studies which include proper site investigation techniques, adapted to the nature of the ground (rock mass or soil) and to the associated engineering problems. The paper illustrates the studies carried out for the design of the foundations of Ribeiradio 76 m high concrete gravity dam in a difficult rock mass and of Vasco da Gama Bridge, 13 km long, crossing the Tagus River in Lisbon, Portugal, through piles 75 m deep.展开更多
