Testing main effects and interaction effects in factorial designs are basic content in statistics textbooks and widely used in various fields. In balanced designs there is general agreement on the appropriate main effect and interaction sums of squares and these are typically displayed in an analysis of variance (ANOVA). A...
Although the synthesis of DNA precursors is
closely coordinated with DNA replication, it is still
not clear whether deoxyribonucleoside triphosphates
(dNTPs) influence DNA replication independently of
their interactions with DNA polymerase catalytic sites.
In an effort to understand the extent to which rate and
fidelity of DNA replication are regulated...
The nature of inheritance and possible associations for traits
influencing earliness and grain yield were investigated using a four
parent diallel of winter and spring wheat cultivars.
More genetic variability was observed for the traits measured in
segregating populations resulting from crosses between winter and spring
type wheats in contrast...
The inhibition of S-aden.osylmethionine: Δ²⁴-sterol methyltransferase
(EC 2.1.1.41) activity by endogenous cellular components has
been studied in vitro. The principal inhibitors were Na⁺ and K⁺; Cs⁺,
NH₄⁺ and Li⁺ were also shown to inhibit the reaction. The inhibition
by potassium cation has been studied, and we have found that energy...
An enzyme system was prepared from Saccharomyces cerevisiae,
strain MCC, which carries out the transfer of the methyl group from
S-adenosylmethionine or methionine to the side chain of yeast sterols.
The cell-free system has been shown to be incapable of synthesizing
ergosterol but carries out the synthesis of two as...
Effects of moisture content, pH, and salt concentration on dynamic rheological properties and gel fracture quality of Pacific whiting surimi were investigated. Torsion tests showed that shear stress decreased rapidly and strain values decreased gradually as moisture concentration increased. As pH increased, fracture shear stress and strain values increased, whereas...
This research addresses fleet-sizing for reusable containers that are used for
protection, transportation, and storage of parts between a component plant and
assembly plant. These reusable containers are often expensive and occupy a
large amount of storage space when empty and full. Having a large container
fleet comes with higher...
Plasma membranes isolated from a yeast sterol auxotroph (RD5-R)
grown on 1,5, and 15 pg m1⁻¹ exogenous concentrations of sterol showed
no discontinuity in plots of steady-state fluorescence anisotropy.
Liposomes constructed from phospholipid and sterol extracted from RD5-R
grown on different sterols indicated exogenously supplied sterol
modulated cellular phospholipids such...
Geometric Problems become increasingly intractable and difficult to visualize as the number of dimensions increases beyond three. Inductions from lower dimensional spaces are possible yet often awkward. This thesis shows how elementary linear algebra, vector calculus, and combinatorics offer improved methods for calculating the dihedral angles of n-simplicies and proving...
