Dynamic Cone Penetrometer is an ideal instrument for testing subgrade and embankment compaction and it in-situ California Bearing Ratio (CBR). The Dynamic Cone Penetration Index (DCPI) value has valid correlation with CBR. The relation has higher value of coefficient of determination, denoted as R<sup>2</sup>, for non-cohesive soils dry soils. The fine grained alluvial soils having some Plasticity Index (PI) value shows the lower R<sup>2</sup> value. The Various alluvial soil samples having PI value from 0 to 10 were tested for finding the moisture correction factor so that DCPI values can be

Depending on the study of the master curve technique, a temperature correction model for the polarization current of transformer polymer (cellulose) insulation, considering the effects of both moisture content (mc%) and temperature is proposed. In the current work, the shift factors of polarization current curves of samples with various moisture contents are extracted at different temperatures. Then, the variation law among the shift factor, test temperature, and moisture content are studied so as to establish the corresponding functional relationship.

Soil moisture content is a critical parameter in understanding the water movement in soil.

The factory-based calibration of the soil moisture sensors is generally developed under limited laboratory conditions, which are not always appropriate for field conditions.

The results showed that as the moisture content increased from 15.1% to 75.2% (w.b.), the true density of wolfberries decreased, but the specific heat capacity and thermal conductivit

Abstract:

The surface fine dead fuel moisture content (FFMC) is an important factor in predicting forest fire risk and is influenced by various meteorological factors. Many prediction methods rely on temperature and humidity as factors, resulting in poor model prediction accuracy under rainfall conditions. At the same time, there is an increasing number of methods based on machine learning, but there is still a lack of comparison with traditional models. Therefore, this paper selected the broad-leaved forest tree species Quercus mongolica and the coniferous forest species Pinus sylvestris var. mongolica

Abstract:

Near-infrared (NIR) spectroscopy can improve the efficiency of soil property prediction, such as that of soil total nitrogen (TN) content. However, soil spectra are very sensitive to soil moisture content, which is a crucial factor affecting the accuracy of soil nutrient composition prediction. In response to this issue, the goal of this study is to identify the best model to correct the effect of soil moisture for predicting soil total nitrogen by near-infrared spectroscopy. The 107 collected soil samples were divided into six different water content (0%, 5%, 10%, 15%, 20%, and 25%) sample gr

A field study of the operation of the IRAMS showed that it operates consistently and repeatedly.

Abstract:

The moisture content in forest harvest residues is a key factor affecting the supply cost for bioenergy production. Fresh harvest residues tend to contain higher amounts of water, thus making transportation inefficient. Additionally, fresh harvest residues contain greater amounts of needles and bark that may reduce the polysaccharide content, thus affecting the production of liquid fuels derived from cellulosic components. In this study, we estimated the downstream economic effect in the supply chain of collecting, grinding, transporting and pretreating fresh versus aged residues. Specifically

Abstract. The active fraction of soil organic carbon is an important component of soil health and often is quickly assessed as the pulse of CO2 released by re-wetting dried soils in short-term (24–72 h) assays. However, soils can lose carbon (C) as they dry and, if soil samples vary in moisture content at sampling, differential C loss during the pre-assay dry-down period may complicate the assay's interpretations. We examined the impact of pre-assay CO2 loss in a long-cultivated agricultural soil at initial moisture contents of 30 %, 50 %, and 70 % water-filled pore space (WFPS). We found that

Therefore, it is of great significance to report a universal approach for extracting αT.

Soil water content conditions can be estimated by remote sensing technology through the vegetation and drought index, and also can be mapped using an interpolation approach. This study aimed to map the optimal soil water content in oil palm plantations based on Normalized Difference Vegetation Index (NDVI), Normalized Multi-band Drought Index (NMDI), and Interpolation.
