Benthic and interstitial habitats of a lentic spring as invertebrate refuges during supra-seasonal drought [PDF]

open access: yes, 2013
Instream refuges are places where invertebrates persist during disturbances due to reduced adverse impacts. During droughts, low flows may be accompanied by elevated temperatures, and potential refuges including subsurface sediments and spring-fed ...

Solar drying of pine lumber: Verification of a mathematical model

open access: yesMaderas: Ciencia y Tecnología, 2014
This work presents verification of a mathematical model for drying of a wood stack in a greenhouse type solar dryer. A simplified heat and mass transfer numerical model has been developed with input parameters based on the actual metrological data of a ...

Numerical simulation of drying of Pinus pseudostrobus wood with Comsol Multiphysics [PDF]

open access: yes, 2014
In this work, we present the second part of our investigation. In the first part, we have published a semi-empirical model for drying. In this second part, we present the numerical solution of a drying model for Pinus pseudostrobus (Mexican softwood ...

Deciphering acoustic emission signals in drought stressed branches: the missing link between source and sensor [PDF]

open access: yes, 2015
When drought occurs in plants, acoustic emission (AE) signals can be detected, but the actual causes of these signals are still unknown. By analyzing the waveforms of the measured signals, it should, however, be possible to trace the characteristics of ...
