Water content in the bio-oil is determined based on the ASTM E203, whereas the moisture content in the biochar is measured in accordance with ASTM D3173 standard. The ASTM D7544 (pyrolysis bio-oil requirements) suggests that the water content in bio-oil be less than 30% on a weight basis...
unconfined compressive strength and specific strength first increase and then decrease with the increase of water content,each of them has an optimum water content,and their curve shapes are similar to parabola.The measured data are analyzed based on the three models,the optimum water content ...
This recalculation assumes that the total weight loss on ignition is due to water loss, which is generally not the case, since some unknown amount of CO2is also presents in cordierite. Thus, the water content specified in the formula is an estimate from above. From the formula, the filling ...
7. Based on the known temperature and relative humidity in the environmental chamber, total suction of the sample was deduced using the Kelvin equation (Eq. 1). Statistical analysis Based on the studies conducted by Bordoloi et al.38 and Ulyett et al.39, both the water content and the ...

The water holding capacity, or soil water retention, describes the relationship between the soil’s matric potential (the difference between pore air pressures and pore water pressure), and its water content (Cornelis et al., 2005; From:Soil and Tillage Research,2019 ...
Based on the Total Hardness (TH) and Electrical Conductivity (EC) values the water samples were found soft to moderately hard and fresh water, respectively. Cluster analysis classified the water samples into three groups such as cluster I (70.97%), cluster II (22.58%) and cluster III (6.45%...
Soluble sodium percentage is about the content of sodium that is significant for the analysis of sodium percentage in the groundwater. Generally, the growth of plants is hindered by higher SSP in groundwater, and the soil permeability is reduced by its reaction (DeSutter et al. 2015). SSP ...
At the second ladder, groundwater iodine content is in the range 0.39 ~ 1006.25 μg/L (mean 28.09 μg/L, median 5.71 μg/L), where the geomorphology is dominated by both plateau/mountain and sedimentary basins. Based on the Local Moran’s Index (see Methods), 80% high-va...
changed (Fig. 3.1) compared to the amendment with biochar, which remained similar to the nonamended control samples. The total porosity estimated from saturated water capacity atmatric potentialof 0kPa reached the highest values for soil samples with 5% manure, though the water content at FC was...
