The purpose of this study is to test the ability of the Land Surface Model SECHIBA to simulate water budget and particularly soil moisture at two different scales: regional and local. The model is forced by NLDAS data set at 1/8th degree resolution over the 1997–1999 period. SECHIBA gives satisfying results in terms of evapotranspiration and runoff over the US compared with four other land surf...

Before 1943, planes could maintain high altitudes for only a few minutes before ignition losses due to moisture condensing in the engines. A simple thickened PDMS grease was the solution and an early example of the excellent dielectric properties of silicones. This application also illustrates key properties of silicones in the electronic industries like hydrophobicity and high dielectric break...

Biomass of legumes grown as catch crops improves soil properties and thus soil conditions for following crops. The aim of this study was to evaluate the effect of field pea (Pisum sativum L.) grown as a catch crop and used for green manure on soil properties and yielding of spring barley (Hordeum vulgare L.). Field experiments were conducted in 2008-2011 in the randomized block design with ...

two parallel needle moisture sensors has been widely used in Soil moisture detection equipment, for example, frequency domain (FD), time domain reflectometry (TDR) and standing wave ratio (SWR) measurement. The design of probe‘s port impedance is key technology parameters to soil moisture sensor. In this study, according to the relationships between the length and impedance characteristics of t...

Understanding what makes a good wood adhesive is difficult since the type of adhesive, wood species, bonding process, and resultant products vary considerably. Wood bonds are subjected to a variety of tests that reflect the different product performance criteria in diverse countries. The most common tests involve some type of moisture resistance; both wood and adhesive factors influence this mo...

Organic matters are the most important factors that affect soil compactability and physical characteristics. In order to study the effect of pistachio waste on physical characteristics of two soils, a factorial experiment was conducted in a completely randomized design with three replications in a greenhouse. The treatments included pistachio waste at 4 levels (0, 3, 6 and 9 w/w %) and two type...

This study aims to evaluate soil moisture and bulk density effects on penetration resistance dynamics of Dark Red Latosol, located in the Microregion of Goiânia, Goias. Area under rotating pasture were sampled 1) in lines and 2) between lines; 3) pasture renewal area; 4) area under Central Pivot; 5) area under no-tillage and 6) forest. Penetrometry tests were done for three different soil moist...
