چکیده
Several classes of isozyme characters are recognized including the number of genes that control a given enzyme system, intralocus and interlocus heteropolymer assembly, tissuespecific gene expression, developmental patterns of enzyme expression, and post-translational modification of gene products. All of these characters can be of value in systematic studies although few applications have been made to date; some of the more robust examples are recognized. Isozyme characters should be evaluated in terms of both their advantages and limitations. The level of universality at which they are used is group-specific. Tissue-specific gene expression data may be of the widest applicability in systematic studies. ( 1999 Elsevier Science Ltd. All rights reserved.

Location models for airline hubs behaving as M/D/c queues
Models are presented for the optimal location of hubs in airline networks, that take into consideration the congestion effects. Hubs, which are the most congested airports, are modeled as M/D/c queuing systems, that is, Poisson arrivals, deterministic service time, and c servers. A formula is derived for the probability of a number of customers in the system, which is later used to propose a pr...
متن کاملOn the Arrangement Graph
The arrangement graph was proposed as a generalization of the star graph topology. In this paper we investigate the topological properties of the (n, k)-arrangement graph &k. It has been shown that the (n, n 2)arrangement graph An,+2 is isomorphic to the n-alternating group graph AGn In addition, the exact value of average distance of A,,& has been derived.

Ð The poor conservation outcomes that followed decades of intrusive resource management strategies and planned development have forced policy makers and scholars to reconsider the role of community in resource use and conservation. In a break from previous work on development which considered communities a hindrance to progressive social change, current writings champion the role of community i...

Isozyme characters, exclusive of allozymes (alleles), are potentially useful in phylogenetic investigations. Such data have been derived from the multilocus L-lactate dehydrogenase (LDH) enzyme system. Among non-avian reptiles, the classes of potential characters include (1) and number of loci encoding LDH, (2) heterotramer patterns, (3) tissue-specific patterns of gene expression, (4) tissue-s...
