Three groups of wires- three strands of 24 gauge stainless steel, 18 gauge Vitailium wire and 16 gauge stainless steel wire were used in this study. The results revealed the braided wire increased the strength slightly when compared to the single str
Evidence That Endogenous Relaxin Promotes Growth of the Vagina and Uterus during Pregnancy in Gilts1

Recently, it was demonstrated that endogenous relaxin promotes growth of the vagina during the second half of pregnancy in rats and that administration of porcine relaxin promotes growth of the uterus in nonpregnant or early pregnant gilts. This stud

In gilts, mammary lobulo-alveolar growth begins on about Day 80 of gestation and continues progressively until term. Relaxin in concert with estrogen plays a major role in promoting this mammary gland growth. The present study was conducted to determ

The objective of this research was to determine the effect of administration of porcine relaxin to gilts during early gestation, or during the follicular phase of the estrous cycle immediately preceding mating, on the length of the uterus and consequ

The role of nonlinearity is explored in a mean-field dynamo model. Magnetic fields are amplified by the combined action of the α andω-effects, and as the field's intensity increases the Lorentz force becomes important. Torsional oscillations and me

Highly supercritical compressible convection is simulated in a two-dimensional domain in which the upper half is unstable to convection while the lower half is stably stratified. This configuration is an idealization of the layers near the base of th

The generation of magnetic fields in stars like the Sun can be described by an azimuthally averaged dynamo model. Solutions of the linear (kinematic) problem have pure dipole or quadrupole symmetry, i.e. toroidal fields that are antisymmetric or symm

An idealized nonlinear αω-dynamo is investigated. Emphasis is placed upon the different spatial symmetries, and the asymmetries that arise after secondary bifurcations. On varying the main control parameter D (the dynamo number), many transitions a

To model penetrative convection at the base of a stellar convection zone we consider two plane parallel, co-rotating Boussinesq layers coupled at their fluid interface. The system is such that the upper layer is unstable to convection while the lower

In order to understand what happens in the Sun when convection overshoots into the radiation zone an idealized model of penetrative convection with rotation is studied. Here we highlight two properties of the model which occur with parameters relevan
