Germination Patterns in Dicotyledons
ABSTRAcr Parallelism as one of the forms of biological similarity is investigated in the light of recent findings from developmental and molecular biology. From the organismic point of view, functional constraints and evolutionary canalization are well established as causes of parallelism. To these may be added, from the molecular perspective, (a) erratic activations of repressed genes; (b) act...
متن کاملLeaf Morphogenesis in Dicotyledons: Current Issues
The last decade of the twentieth century has witnessed a period of renewed interest, redefinition of questions, and some dramatic advances toward resolving some of the long-standing issues related to the developmental regulation of leaf morphogenesis. New interest has been sparked by the application of developmental genetics, molecular biology, and mosaic analysis to the study of genetic model ...

The authors review extant research on threats, approaches, attacks, and assassinations of public figures in the United States. Despite the limited number of studies, data exist concerning: 1) threatening letters and approaches to celebrities; 2) attacks and assassinations of public figures, usually the President of the United States; 3) threats and approaches to legislative members of state and...
متن کاملComparative Placentation
The ancestry of horses from five-toed species via the small Eohippus of the American continent has been a prime topic of study for evolutionary biologists. It is best traced in two contributions: by Simpson (1951), and by Thenius & Hofer (1960). Coming from the American continent, the equid ancestors distributed to Eurasia while speciating into the extant members during their expansion to the W...

We propose an alternative characterisation of object-based distributed systems in terms of algebraic structures and topological spaces. Some examples are given in order to attest the adequacy of this approach to the subject. We also illustrate a method of transference of results from these mathematical theories that can further contribute to the advancement of distributed systems theory.
