A Study Of The Respiratory System Of The Sparrow (Passer Domesticus), Ben Peter Arnowitz
A Study Of The Respiratory System Of The Sparrow (Passer Domesticus), Ben Peter Arnowitz
Bachelors’ Theses
The respiratory mechanisms of birds, unlike that of mammals, are definitely adapted to the function of flight. Because of this added adaptation, we should expect, therefore, some morphological and perhaps even embryological, physiological, and histological differences. An example of a morphological difference between birds and mammals is the intricate system of air-sacs that are present in birds. This remarkable feature is probably the reason why birds are able to fly as they do.
In this thesis the writer has used the sparrow (Passer domesticus) for the basis of his experiments. This particular bird was chosen in preference to …
The Influence Of Dowicide A On Drosophila Melanogaster, Helen Mary Dore
The Influence Of Dowicide A On Drosophila Melanogaster, Helen Mary Dore
Bachelors’ Theses
Drosophila melanogaster plays a far greater part in science than man at first realizes. A study of their heredity makes it possible to develop laws of human heredity and with this knowledge, thus provide for the betterment of mankind. Considerations which lead to the choice of the fruit fly, Drosophila melanogaster, in experimentation are briefly the following: (a) its small size which makes, it convenient to keep; (b) its short life cycle; and (c) the ease with which it can be cultivated. Since fruit flies are so important to science, it follows that it is also important that a …
An Electrophoretic Determinatin Of The Properties Of Methacrol M.E. By The Use Of A Capillary Cross-Arm "U" Tube, Richard Reiland Bains
An Electrophoretic Determinatin Of The Properties Of Methacrol M.E. By The Use Of A Capillary Cross-Arm "U" Tube, Richard Reiland Bains
Bachelors’ Theses
this research was undertaken primarily to discover the use of a capillary cross-arm "U" tube in the determination of the electrophoretic and other electrical proper ties of a plastic emulsion.
The primary objective was to determine the isoelectric point of the emulsion and also the optimum pH or electro-endosmotic motion.
The secondary and distant objective was to note when, how, and it any coherent plating on the electrodes took place.
