With respect to HD policy, for a long period, intellectual reluctance, the tendency to institutional permanence, dynamic conservatism, efficacious anti-termination coalitions, and legal obstacles certainly posed difficulties for policy changes in both countries[ 139, 140].
The models mainly study the population dynamic behaviors, for example, permanence, extinction, global attractivity, etc.
Anyone who recalls the much larger demonstrations of late 1995, which brought the Juppé government to an end, over pension reforms that seem, in retrospect, minute, will recognize the permanence of the dynamic.
In Section 3, the dynamic behaviors such as the permanence, extinction, and the globally attractivity of the system are investigated.
By establishing some dynamic inequalities on time scales, a permanence result for the model is obtained.
However, what they have found was the equivalence between satisfaction of inequality (15) and the permanence of the predator-prey dynamic systems with Beddington-DeAngelis-type function response.
The principle aim of this article is to study the dynamic behaviors of system (1.3), such as permanence, global attractivity, existence, and global attractivity of positive periodic solutions.
Interactions are associated with several dynamic characteristics, such as their direction, strength, permanence or transience, and presence or absence [ 6].
The biggest disadvantage of permanent fillers is their permanence.
Choosing a major informatics supplier such as IDBS, PerkinElmer, or Accelrys might give some assurance of permanence, but the market is so dynamic that any vendor will likely undergo changes.
