Master's Theses
Among factors necessary for an animal to maintain life is the presence of an oxygen carrier that will transport a sufficient quantity of oxygen necessary for respiratory metabolism. In animals whose blood contains hemoglobin, which is a pigment that loads and unloads oxygen, this carrying capacity is referred to as blood oxygen capacity. It is a measure of the amount of oxygen that will combine with whole blood when completely mixed with air. It is usually expressed in volumes per cent (ml. 02/100 ml. blood) and corrected to standard temperature and pressure.
A search of available literature revealed that there …

A Critical Study Of The Chromosomes In Two Species Of Myxophyceae, John Thomas Mullins
Master's Theses
The Myxophyoeae or blue-green algae have been frequent subjects for cytological investigation since Schmitz (1879) first called attention to two regions in the protoplast. Since that publication the morphological and chemical nature of the genetic material and the mechanism of cell division in the Myxophyceae has been a controversial subject, The evidence that has been presented is, tor the most part, more voluminous than enlightening.
This investigation was undertaken in order to verify the methods and check the results obtained with the smear technique by Strickland (1948). Additional methods were also applied which might enable a more critical evaluation of …
