It was also observed that even though degradation occurred at a faster rate at the reinforced strut of the stent where there was an increase in the low molecular weight chains, there was hereby limited impact on the weight-average molecular weight of the stent. The experiment results about the trends in the Tubeimoside-I<\/a> radial strength have proven that the weight-averaged molecular weight is a very important factor determining the supporting performance of the stent, with however limited influence on the radial supporting property. In summary, it is feasible to use the finite element model to predict the changes in the radial strength of bioabsorbable cardiovascular stents after degradation. However, in order to obtain more accurate analysis results, more comprehensive and accurate experimental data about the degradation and mechanical properties of the material are required. The relationship between sexual fitness and population fitness is not generally understood. Theory indicates that sexual selection can increase beneficial allele fixation, deleterious allele removal,, and the rate of adaptation to novel environments. Experiments have been ambiguous. In D. melanogaster sexual selection sometimes removes specific deleterious marker mutations. Attempts to measure sexual Gentamycin Sulfate<\/a> selection’s effect on non-specific mutational load have been mixed. Bulb mite populations held under relaxed viability and fecundity selection showed no improvement in the presence of sexual selection. With the addition of ionizing radiation, sexual selection increased fitness. But when reintroducing viability and fecundity selection, sexual selection no longer showed a detectable benefit. When natural selection was relaxed in D. serrata, sexual selection improved productivity. Dung beetles were exposed to ionizing radiation and then held with\/without sexual selection for two generations. Male strength and female productivity were both higher in the sexually selected treatment. Sexual selection did not increase the rate adaptation to a thermally stressful environment in D. melanogaster, or novel larval food resource in D. serrata. Sexual selection did increase the rate of adaptation of a seed beetle to a novel host plant, yet, decreased fitness when maintained on their ancestral host. In a particularly thorough experiment, D. melanogaster populations were exposed to EMS, then held with\/without sexual selection for 60 generations, at which point the populations were evaluated in both mating environments. Net reproductive rate actually went down in the sexually selected populations, apparently because the costs of sexual selection exceeded any benefits. With sexual selection comes intersexual conflict, which has sometimes favored the evolution of male traits that directly harm females.. A few experiments with D. melanogaster have assessed the direct costs and indirect benefits, finding that the net effect was substantially negative. The inconsistent results among experiments designed to find benefits to females of sexual selection, may, in part, be due to a lack of control of sexual conflict. Most of those experiments removed sexual selection through enforced monogamy with random mate assignment. Under monogamy, the reproductive success of a mating pair is identical. Therefore, ancestral sources of conflict are new opportunities for adaptation. As sexually antagonistic, femaleharm, alleles are removed under monogamy, fitness measures may improve despite the concurrent removal of any benefits of sexual selection. Despite the difference in net reproductive rate, Hollis and Houle found no difference in egg-to-adult viability or fecundity, also illustrating the difficulty of drawing inferences about fitness from its components, where measurement context may differ.<\/p>\n","protected":false},"excerpt":{"rendered":"
