[1] The radar backscattering coefficient is mainly determined by surface soil moisture, vegetation and land surface roughness under a given configuration of the satellite sensor. It is observed that the temporal variations of the three variables are different, the variation of vegetation and roughness are at the longer temporal scales corresponding to climate and cultivation practices, while so...

Near infrared (NIR) spectroscopy technique serves as an important tool for the measurement of moisture content of skin owing to the advantages it has over the other techniques. The purpose of the study is to develop a correlation between NIR spectrometer with electrical conventional techniques for skin moisture measurement. A non-invasive measurement of moisture content of skin was performed on...

The green weight of southern pine tree-length roundwood delivered to the pulp mill is generally known. However, for optimum mill efficiency it is desirable to know dry weight. The moisture content of tree-length pine logs is quite variable. The moisture content of pine tree-length logs increases significantly with increasing stem height. Moisture content also varies with tree age and geographic...

Since its introduction in 1940, the plaster of Paris block method of measuring soil moisture by means of electrical resistance (4) has been widely employed in agricultural fields. Hydrologic research2 (16), war production problems involving guayule culture (11, 12), and many other investigations ranging from field irrigation to greenhouse studies have made use of this technique. Briefly, the me...

A peer-verified method is presented for the determination of percent moisture and fat in meat products by microwave drying and nuclear magnetic resonance (NMR) analysis. The method involves determining the moisture content of meat samples by microwave drying and using the dried sample to determine the fat content by NMR analysis. Both the submitting and peer laboratories analyzed 5 meat product...
