Modularity of a Cambrian ptychoparioid trilobite cranidium.
Modularity of the cranidium of Crassifimbra? metalaspis, a Cambrian ptychoparioid trilobite, is investigated using landmark-based geometric morphometric methods to gain insight into the integration among morphogenetic processes responsible for shaping the head of an ancient arthropod. Of particular interest is the extent to which the structure of phenotypic integration was governed by direct in...
متن کاملnew semigroup compactifications via the enveloping semigroups of associated flows
this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.
15 صفحه اولNewer Insights into the Prsevention of the Common Cold
Since most colds are self-limiting, symptoms will usually resolve on their own in seven to ten days. For the majority of patients, treatment is symptomatic and targeted at the most bothersome symptoms. Specific nonprescription therapy may relieve cold symptoms but should be used with caution, especially in at-risk patient populations. Patients should monitor for worsening symptoms, and progress...
متن کاملTrilobite body patterning and the evolution of arthropod tagmosis.
Preservation permitting patterns of developmental evolution can be reconstructed within long extinct clades, and the rich fossil record of trilobite ontogeny and phylogeny provides an unparalleled opportunity for doing so. Furthermore, knowledge of Hox gene expression patterns among living arthropods permit inferences about possible Hox gene deployment in trilobites. The trilobite anteroposteri...
