The expression (px_{2}(t)/(q+x_{2}^{n}(t))) is a birth rates function of the susceptible pest population.
The women describe that they wanted to experience a natural birth and the function of the female body [ 18, 20, 31], by working with the body [ 19], active participation [ 19], and giving their body an opportunity to experience natural childbirth [ 19].
Because the Isl2 null mutant pups died within 24 h after birth, the function of Isl2 during the eye-specific refinement is unknown.
With birth, the function of gas exchange is transferred from the placenta to the lungs, and therefore from the systemic circulation to the pulmonary circulation.
The model follows the basic form of models produced by Anderson & May 19811) except that the host population is assumed to be dioecious and its birth rate is a function of the number of females.
We intended in this study to explain the variation in birth outcomes as a function of the individual and area-based level SEM, measures of traffic and land use as indices of physical environment, and their interaction using a two-level hierarchical model.
Our choice of birth function also implicitly assumes random mating among healthy and parasitized individuals.
The potential for an Allee effect [36], [37] is implicit in our choice of birth function (equation 9).
These results imply that patterns of age-dependent plasticity during the early juvenile period might predictably vary among genotypes that express different levels of behaviour at birth or hatching, as a function of the cues with which those genotypes were reared and tested.
We perform mean-field calculations as well as simulations to find the steady-state fraction of occupied vertices as a function of the birth rate.
