BACKGROUND Debate about the health implications of using smokeless tobacco products (STPs) has prompted considerable interest in characterising their levels of toxic and carcinogenic components. In the present study seventy smokeless tobacco products from the US and Sweden, categorized as chewing tobacco, dry and moist snuff, hard and soft pellets, plug,(More)
Effects of waves and the free surface on a surface-piercing flat-plate turbulent boundary layer and wake." ii To my parents iii ACKNOWLEDGMENTS I wish to acknowledge all of those who have lent their time, labor, and expertise in order to complete the experiments and this thesis. This study reflects not only my work but that of a collaborative effort. I(More)
BACKGROUND Due to the lower health risks associated with the use of certain categories of smokeless tobacco products (STPs) such as Swedish snus, there is interest in the comparative levels of toxic chemical constituents in different types of STPs. A method has been developed and validated for the analysis of hydrazine in STPs. Seventy four commercial STPs(More)
BACKGROUND There is considerable interest from a regulatory and public health perspective in harmful and potentially harmful constituents in tobacco products, including smokeless tobacco products (STPs). A wide range of commercial STPs from the US and Sweden, representing 80-90 % of the 2010 market share for all the major STP categories in these two(More)
The purpose of this study was to examine the effects of reductions in blood volume and associated oxygen-carrying capacity on the incidence of plateau at $$\dot{V}{\text{O}}$$ V ˙ O 2max. Fifteen well-trained athletes (age 23.3 ± 4.5; mass 77.4 ± 13.1 kg, height 180.1 ± 6.0 cm) completed three incremental cycle tests to volitional exhaustion, of which the(More)
Acknowledgements This work could not have been done without a great deal of guidance from both my advisor, Dr. Barrick, and two of his students, Vini Reynoso and Alvaro Rodriguez. These three were patient with my paltry knowledge of biochemistry and wet lab techniques. I slowly learned to understand the vernacular, and can now even include some of it in my(More)
