Update on Root Exudation and Rhizosphere Biology Root Exudation and Rhizosphere Biology

Our understanding of the biology, biochemistry, and genetic development of roots has considerably improved during the last decade (Smith and Fedoroff, 1995; Flores et al., 1999; Benfey and Scheres, 2000). In contrast, the processes mediated by roots in the rhizosphere such as the secretion of root border cells and root exudates are not yet well understood (Hawes et al., 2000). In addition to th...

A clinical consideration of cor pulmonale.

Definition T HE term cor pulmonale is genierally used to define the cardiac complications of certain forms of lung disease. From knowledge gathered in the recent past, it is apparent that a number of disease processes that attack pulmonary funetioni in a variety of ways can produce circulatory embarrassment. The mechanisms by which they do so may be fundamentally different and indeed the lungs ...

Consideration on Hemicraniectomy

Decompressive hemicraniectomy is a surgical technique used to relieve the increased intracranial pressure. There is no standardized surgical technique to clearly state the minimum area of the cranial vault needed to obtain the best results. The aim of the current paper is to present our surgical technique and experience used in performing hemicraniectomies, technique that we consider optimal fo...

A Mathematical Model for Maple Sap Exudation

Physical Background. Sap exudation refers to the process whereby sugar maple trees (Acer saccharum) are capable of generating significant stem pressure in a leafless state, something that occurs to a lesser extent in only a few other related species such as birch and walnut. This exudation pressure is what causes maple sap to flow from a taphole in sufficient quantities to be harvested and proc...
