In the dissertation, I address two of the fundamental questions of the fallout controversy: Was there a threshold of radiation...

Fluorimetric analysis of intracellular calcium in high and low mobility fowl sperm

Creator:

Olson, Jill Wardell

Abstract:

Sperm mobility is defined as the net movement of a sperm population against resistance. Previous research demonstrated that the cell-permeant Ca2+ indicator rhod-2 AM gave a fluorescent signal predominantly in the head region of fowl sperm that differed between sperm mobility phenotypes. This thesis served to explore the role of...

Using ship tracks to characterize the effects of haze on cloud properties

Creator:

Segrin, Matthew S.

Abstract:

1-km MODIS observations of ship tracks off the west coast of the U.S. are used to characterize changes in cloud visible optical depths, cloud droplet radii, cloud cover fraction, and column cloud liquid water amount as low-level marine clouds respond to particle pollution from underlying ships. This study re-examines the...
