Molecular and biological characteristics of avian polyomaviruses: isolates from different species of birds indicate that avian polyomaviruses form a distinct subgenus within the polyomavirus genus.
The isolation and characterization of two avian polyomaviruses, from chicken (BFDV-2) and a parrot (BFDV-3), is reported. Both isolates are closely related to the non-mammalian polyomavirus budgerigar fledgling disease virus (BFDV) isolated from budgerigars (now called BFDV-1), and all three viral genomes are shown to have the same basic size of 4981 bp. A 151 bp insertion was, however, observe...
متن کاملidentifying areas that are outside of fire stations services
aid uses, including fire stations, according to critical activities that are responsible, in comparison to other city services, are more important. identify areas where are located outside of the fire stations covered services can help urban planners to site selection of this important land use. the purpose of this paper is detection the areas that are beyond the services coverage of the fire s...
متن کاملHsp70 sequences indicate that choanoflagellates are closely related to animals
Over 130 years ago, James-Clark noted a remarkable structural similarity between the feeding cells of sponges (choanocytes) and a group of free-living protists, the choanoflagellates. Both cell types possess a single flagellum surrounded by a collar of fine tentacles. The similarity led to the hypothesis that sponges, and, by implication, other animals, evolved from choanoflagellate-like ancest...
متن کاملBroad taxon and gene sampling indicate that chaetognaths are protostomes
Despite advances in phylogenetic methods, there are still a number of enigmatic phyla whose affinities remain poorly resolved. One of the most recalcitrant of these is a group of small predatory marine invertebrates, the chaetognaths (arrow worms). Resolution of the phylogenetic position of the chaetognaths is key for reconstructing the evolutionary history of some of the most fundamental featu...
متن کاملMULTIPLICATION MODULES THAT ARE FINITELY GENERATED
Let $R$ be a commutative ring with identity and $M$ be a unitary $R$-module. An $R$-module $M$ is called a multiplication module if for every submodule $N$ of $M$ there exists an ideal $I$ of $R$ such that $N = IM$. It is shown that over a Noetherian domain $R$ with dim$(R)leq 1$, multiplication modules are precisely cyclic or isomorphic to an invertible ideal of $R$. Moreover, we give a charac...
