We compared the time for bone healing after high tibial osteotomy in snuffers, smokers, and in control subjects who did not use snuff or cigarettes. Patients and methods 175 male patien

Development and Application of Non-linear Mid-infrared Laser Spectroscopy for Combustion Diagnostics

The work reported in this thesis involved the development and application of two novel infrared non-linear laser techniques, namely mid-infrared polarization spectroscopy (IRPS) and mid-infrared degenerate four-wave mixing (IR-DFWM) to combustion diagnostics. These two techniques meet the needs of species concentration detection in combustion environments, especially for those species lacking acce

We utilised a questionnaire to investigate how members of 13 PACPs motivated their memberships. The study included 1,810 individuals who had been treated for breast cancer, gynaecological cancer, or prostate cancer. Through questionnaires these individuals were asked to articulate why the
