Topological Defects in Gravitational Theories with Non Linear Lagrangians
The gravitational field of monopoles, cosmic strings and domain walls is
studied in the quadratic gravitational theory with , and is compared with the result in Einstein's theory. The metric
aquires modifications which correspond to a short range `Newtonian' potential
for gauge cosmic strings, gauge monopoles and domain walls and to a long range
one for global monopoles and global cosmic strings. In this theory the
corrections turn out to be attractive for all the defects. We explain, however,
that the sign of these corrections in general depends on the particular higher
order derivative theory and topological defect under consideration. The
possible relevance of our results to the study of the evolution of topological
defects in the early universe is pointed out.Comment: LaTeX (uses revrex macros), 13 page
Charged black holes in effective string theory
We investigate the qualitative new features of charged dilatonic black holes
which emerge when both the Yang-Mills and Gauss-Bonnet curvature corrections
are included in the effective action. We consider perturbative effects by an
expansion up to second order in the inverse string tension on the four
dimensional Schwarzschild background and determine the backreaction. We
calculate the thermodynamical functions and show that for magnetic charge above
a critical value, the temperature of the black hole has a maximum and goes to
zero for a finite value of the mass. This indicates that the conventional
Hawking evaporation law is modified by string theory at a classical level.Comment: 17 pages, 5 figures not included, plain Te
Perinatal Exposure to Environmentally Relevant Levels of Bisphenol A Decreases Fertility and Fecundity in CD-1 Mice
Bac k g r o u n d: Perinatal exposure to low-doses of bisphenol A (BPA) results in alterations in the ovary, uterus, and mammary glands and in a sexually dimorphic region of the brain known to be important for estrous cyclicity. Objectives: We aimed to determine whether perinatal exposure to environmentally relevant doses of BPA alters reproductive capacity. Met h o d s: Female CD-1 mice that were exposed to BPA at 0, 25 ng, 250 ng, or 25 µg/kg body weight (BW)/day or diethylstilbestrol (DES) at 10 ng/kg BW/day (positive control) from gestational day 8 through day 16 of lactation were continuously housed with proven breeder males for 32 weeks starting at 2 months of age. At each delivery, pups born to these mating pairs were removed. The cumulative number of pups, number of deliveries, and litter size were recorded. The purity of the BPA used in this and our previous studies was assessed using HPLC, mass spectrometry, and nuclear magnetic resonance. Res u l t s: The forced breeding experiment revealed a decrease in the cumulative number of pups, observed as a nonmonotonic dose–response effect, and a decline in fertility and fecundity over time in female mice exposed perinatally to BPA. The BPA was 97 % pure, with no evidence of contaminatio
