a pressure-based coupled heat and mass transfer model was used to simulate temperature and soil suction in a drying process within a clay soil column. closed form functions were used for all parameters needed in the governing equations. model predictions were compared with experimental data using the mean relative percentage deviation method. thermocouples and mini-gypsum blocks were used t...

Many studies have reported tree growth reduction in forests with pedestrian trampling, implying a reduction of tree transpiration in such forests. We undertook observations of tree transpiration based on the heat-pulse method in a forest (Lithocarpus edulis) with pedestrian trampling. We prepared trampled and control plots in the forest. Tree transpiration in the trampled plot was reduced compa...

A field experiment was conducted for two years to find out best water management practice to mitigate methane emission from the rice-fields. Continuously flooded conditions yielded two major flushes of methane emission and on an average resulted in relatively higher rate of methane emission (2.20 and 1.30 mg m(-2) hr(-1), respectively in 2005 and 2006) during the kharif season. The methane flux...

in order to investigate the effect of soil matric potential and tube layout on yield and water use efficiency of greenhouse cucumber, a field experiment was carried out during 2010 and 2012 growing seasons at an experimental farm in jiroft territory. the treatments were laid out in strip split plot a randomized complete block design with three replications. the treatments were comprised of fore...

In this paper, we study the Bauer-Fike type theorems for regular matrix pairs and its general form. Besides these, we also obtain some bounds for measuring approximate generalized eigenvalues and for the perturbation of generalized eigenvalues concerning an approximate generalized invariant subspace. To estimate all these bounds, p-Hölder norm and an ad hoc pseudo-metric called p-Chordal matric...

The current paper aims to analyze the influence of installation procedures when it comes accordance Soil Water Retention Curve and field monitoring data. method comprises testing three different procedures: with driving rod into soil; application mud inside auger hole; a hardened steel gauge. Further, is evaluated variation Bulk density on volumetric water content values by using Proctor double...
