Abstract— Over the past years a great deal of work has been done in the field of tooth root resorption but notwithstanding this, understanding of the subject has progressed very little. This paper reviews the subject and suggests ways of minimizing root resorption or perhaps even eliminating it.

In this work we study the problem of determining an unambiguous p-root of a language, i.e. a solution of the equation Xp=L when L is a language and the product is unambiguous. We show that every language admits at most one unambiguous root and that the problem of the existence of the unambiguous root is undecidable for the class of context free ...

Plant Science![Figure][1] CREDIT: DIANE DIEDERICH/ISTOCK PHOTO Too much salt is as bad for plants as it is for us. For plants, salt stress and drought stress go hand in hand. Some of the more rapid responses to salt stress are signaled through actions of the sucrose nonfermenting ...

Nodulin gene expression is an integral and highly specific part of the formation of nitrogen‐fixing nodules on the roots of leguminous plants. Dependent on the time of expression during root nodule development, nodulin genes can be divided into early and late nodulin genes.

Root Growth and Rooting of Basswood
Botanical Gazette, 1968Seedling root growth of basswood (Tilia americana L.) was observed in soil pits between nursery rows, in pots (by inverting the soil ball), and in Lucite cylinders in the greenhouse. Root growth occurred primarily during late spring, summer, and fall in the nursery. It occurred throughout the year in the greenhouse.

On generation of the root lattice by roots
Mathematical Proceedings of the Cambridge Philosophical Society, 2007AbstractLet Φ be a root system and let Γ ⊆ Φ. In this short paper we prove that Γ contains a ${\mathbb Z}$-basis of the lattice that it generates.
