6. The result of quantitative analysis on the prior protection is that, of 68 species of the rare and endangered plants in Chongqing, there are 6 endangered plants, 27 vulnerable plants, 32 rare plants, and 3 "safe" plants.
Intermetallic compound Al 20 Ti 2La ,which is fine,uniform in dispersion as well as good thermal stability,can be formed in RS Al-Ti-La alloy It is supposed that the intermetallic phase forms prior to the others, and the twin crystal formation is vital in the nucleation stage
The adsorption potential of ~(13)CH_4 on coal is higher than ~(12)CH_4.This implies that the coal is preference for ~(13)CH_4 adsorption and postponement for ~(13)CH_4 desorption,and it is favorable for ~(12)CH_4 fractionation.
Virtual waiting times in priority-M/G/1 queues with vacations
In this paper exhaustive-service priority-M/G/1 queueing systems with multiple vacations, single vacation and setup times are studied under the nonpreemptive and preemptive resume priority disciplines.
The protocol is founded on time division multiplex address and a different type of traffic is assigned to different priority, according to which a node should compete for and reserve the free slots in a different method.
In these strategies, a tuple with the highest priority is selected to process from multiple candidates.
However, the performance of these static strategies is deeply influenced when data are bursting, because the priority is determined only by static information, such as the query windows, arriving order, etc.
Plant species frequently well adapt to their original "nutrition habitat" during a long process of evolution, and the apparent preference for ammonium or nitrate nitrogen source (NH4+ or NO3-) might be an important aspect of the adaptation.
Similar to habitat selection by the species during winter, blue sheep also showed a preference for mountain savanna with tree dominated by Ulmus glaucescens and medium tree density (>amp;lt; 4 individuals / 400 m2) during spring.
The olfactory responses of Anoplophora glabripennis to the odors of different plants showed preference for certain host plants: Acer negundo, Acer mono and Acer truncatum.
The qualitative concept of the risk aversion is defined in terms of a preference relation on a set of probability distributions.
Papers on the construction of preference relations by an additive aim function having multiple inexact (interval) estimates for its coefficients are briefly reviewed.
