Coulomb’s Theory for Earth Pressure | Soil
In this article we have compiled three main theories given by Coulomb for studying earth pressure. The theories are: 1. Coulomb’s Wedge Theory for Earth Pressure 2. Coulomb’s Theory of Active Earth Pressure 3. Coulomb’s Theory for Passive Earth Pressure. 1. Coulomb’s Wedge Theory for Earth Pressure: Coulomb (1776) developed the wedge theory for determination […]
Top 5 Theories of Ion Uptake by Plants
This article throws light upon the top five theories of ion uptake by plants. The theories are: 1. Lundegardh Theory 2. Contact Exchange Theory 3. Carbonic Acid Exchange Theory 4. Bennet-Clark’s Protein Lecithin Theory 5. Donnans’ Equilibrium Theory. 1. Lundegardh Theory (Electro-Chemical Theory) of Ion Uptake: Lundegardh (1945) proposed that an electrical potential gradient existing […]
