The caps of the roots of Zea mays (var. Kelvedon 33) are the source of a growth inhibitor system which also acts on the root elongation of Lens culinaris.

Root–Root Interactions: Towards A Rhizosphere Framework
Trends in Plant Science, 2016Plant scientists have made great progress in understanding molecular mechanisms controlling root responses to nutrients of arabidopsis (Arabidopsis thaliana) plants under controlled conditions. Simultaneously, ecologists and agronomists have demonstrated that root-root interactions involve more than competition for nutrients.

This chapter establishes the importance of African American shop workers to Texas railroad hubs such as Marshall, Texas, and explores black responses to the 1922 National Railroad Shopmen’s Strike. Newspaper sources reveal that, while some Texas black and white shopmen cooperated in the 1922 walkout, 216 black shopmen in Marshall dramatically broke ...

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 ...

A t one time, scientists thought that mountains and valleys arise because the earth is shrinking; all the wrinkles, folds, faults and other deformations in the planet's crust were likened to the crinkly skin of a drying apple. Then came the theory of plate tectonics, which revolutionized the earth sciences and gave researchers a more tenable framework ...

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.

S'appuyant sur les travaux de L. Febvre et D. Wotton, l'A. retrace l'historiographie des preuves et des persuasions qui ont contribue au debat sur l'incroyance et l'atheisme, depuis le spinozisme jusqu'au neorepublicanisme, et depuis le christianisme primitif jusqu'a l'heterodoxie ...
