The equine endometrial biopsy, an important tool in equine reproduction science, has experienced a rich period of increasing knowledge, development, and application over the past 40 y. Much of the foundational work in this field was conducted by Dr. Robert M. Kenney. In view of his recent passing, this review is dedicated to our alumnus, Dr. Robert M. Kenney (OSU, 1954). In this manuscript, we pay tribute to Kenney—eponymous for the equine Air Jordan 4 Vancouver
endometrial biopsy grading system—by reviewing the Air Jordan 1 Toronto
procedure. We present this review in three parts: 1) how observational data are acquired; 2) how these data are interpreted; and 3) how these data are applied in equine reproduction science and medicine.
The effect of the activation temperature on acid-base properties of alumina catalysts was studied. The acidity and basicity of catalysts were characterised by using the dynamic sorption method and by testing the catalyst activity in the depolymerisation of paraldehyde and decomposition of diacetone alcohol. For all catalysts, it was found that the acidity increases significantly with increasing activation temperature up to 550°C, whereas the basicity goes through a maximum at 140°C. The acidity Air Jordan Retro 1 Canada of alumina increases with increasing surface dehydration. Maximum basicity corresponds to a surface covered completely with hydroxyl groups.
