Maximum plant height and the biophysical factors that limit it

Zonation of Flood Susceptibility and Determining the Factors Affecting it Using the Maximum Entropy Method

Karaj dam basin in Alborz province is prone to destructive floods given to its special topographic and anthropogenic conditions. The purpose of this study is to determine the areas with flood susceptibility potential and prioritize the factors affecting it using the maximum entropy method. 14 factors affecting flood potential selection and linear testing Factors were analyzed by variance inflat...

Potential factors that may limit the effectiveness of silage additives

Introduction Various microorganisms, enzymes, nutritive and chemical compounds have been added to forages to maintain or improve the nutritive value of a crop as silage (Kung et al., 2003). As is the nature of most biological systems, there is considerable variation in the outcome of using these additives. This paper will briefly discuss some universal and specific challenges that these additiv...

Corrigendum: The height limit of a siphon

We wish to acknowledge a related 1995 experiment performed by Andrew K Fletcher (http://inclinedbedtherapy. com), in which a 48 m length of 6 mm bore tubing, filled with degassed water was lifted 24 m vertical against Brixham Cliffs. A 50 ml bolus of coloured saline solution in the middle of the 48 m tubing was introduced prior to the tubing being raised to 24 metres vertical by its centre as a...

The height limit of a siphon

The maximum height of a siphon is generally assumed to be dependent on barometric pressure-about 10 m at sea level. This limit arises because the pressure in a siphon above the upper reservoir level is below the ambient pressure, and when the height of a siphon approaches 10 m, the pressure at the crown of the siphon falls below the vapour pressure of water causing water to boil breaking the co...
