Objectives of this study were to examine effects of dietary pyrrolizidine alkaloids (PA) on copper and vitamin A metabolism in the chicken which are very susceptible to the hepatoxic effects of PA and Japanese quail which are highly resistant to PA. Also, the possible interaction between copper and vitamin A...
Proving mathematical theorems usually involves the proof of
an implication, p --> q. Often it is convenient to prove the implication
by proving one which is equivalent to or "stronger" than the original
theorem. Proofs of this type are called indirect proofs.
In Chapter I five forms of indirect proofs...
Currently little is known about the mechanisms and locations of
lymphocyte development in teleosts. In this study several aspects of the
underlying factors which govern B lymphocyte development in trout
were investigated which included: the isolation and characterization of
immunoglobulin heavy chain (IgH) genes, the recombination activating
genes 1 and...
Chronic hepatitis B disproportionately affects Asian Americans. Although Asians make up only 4.2% of the total United States (U.S.) population, they account for more than half of those infected with hepatitis B. If left untreated, chronic hepatitis B could lead to cirrhosis, liver damage, and liver cancer. Studies show that...
A series of experiments was designed to investigate differential
flood-tolerance and the phenomenon of flood-induced stomatal closure
of several fruit tree species. The first two experiments were conducted
with potted plants submerged outdoors 5-10 cm above the soil line.
Plant morphology, growth, leaf conductance (cL), and soil oxygen diffusion
rate...
Private set intersection (PSI) allows two parties, who each hold a set of items, to compute the intersection of those sets without revealing anything about other items. Recent advances in PSI have significantly improved its performance for the case of semi-honest security, making semi-honest PSI a practical alternative to insecure...
Honey bees mark artificial flowers with scents that
advertise about the previous history of the flower to
subsequent foragers. Unrewarding flowers are marked with a
scent, after a single visit, that makes the flower less
attractive to subsequent foragers. Previously rewarding
flowers are initially less attractive than unvisited
flowers but...
