6. The microstructures of Ti-6Al-4V and Ti-6Al-2Sn-4Zr-6Mo and their relationship to processing and properties
Abstract : The research described in the thesis concerns phase transformations and mechanical properties of the titanium alloys Ti-6Al-4V and Ti-6Al-2Sn-4Zr-6Mo. The need to weld the alloys for certain engine components can expose the alloy locally to non-optimum thermal cycles and it is therefore of importance to gain an understanding of the kinetics involved in the phase transformations during heating and cooling.

7. Immigration, security and the public debate on US language policy : A critical discourse analysis of language attitudes in the United States of America
Abstract : The narrative of the United States is of a "nation of immigrants" in which the language shift patterns of earlier ethnolinguistic groups have tended towards linguistic assimilation through English. In recent years, however, changes in the demographic landscape and language maintenance by non-English speaking immigrants, particularly Hispanics, have been perceived as threats and have led to calls for an official English language policy.

8. Microwave sensors for scanning of sawn timber
Abstract : A microwave imaging sensor that measures the signal transmitted through a board was investigated with respect to the ability to predict the distribution of moisture and density in sawn lumber. Furthermore, the response from the sensor was related to strength properties of the boards. READ MORE

9. Studies on Industrial-Scale Thermal Modification of Wood
Abstract : Wood as a raw material is useful for many purposes even though some properties are less than optimal, for example, dimensional stability and durability. These characteristics can however be improved by different treatment methods. READ MORE

10. Erosion of rock with a water jet
Abstract : During the last decade destruction of rock with the aid of a high speed water jet has been the subject of great interest. Most papers published in this field deal with experiments but very little has been done theoretically. READ MORE
