PROBLEM TO BE SOLVED: To provide a method for testing wet density of soil, which is simple and also capable of obtaining, at a low cost, an approximate value of a region that causes no harmful influence on the actual construction work.MAKINO MASAKI牧野 昌己NODA MASAMICHI野田 昌道...
Particle density—is the density of solid soil particles only, i.e., measurement does not include pore space (air space), the average value is 2.65 g cm−3. Bulk density—is the density of a volume of soil as it exists naturally, it includes air space, organic matter, and soil ...
fast-maturing organisms like soil invertebrates can colonise and reach adult size much faster than large trees (Figure 1, Scenario 1; Calcagno et al., 2023; White et al., 2007) and may have a fully realised body size spectrum within a few years of colonisation (Calcagno et al., 2023)....
The total degeneracy of λS is hence (n − 1)(2n + 1). For completeness, we also give the formula for the total energy (1.A8)HtotAv=TrH2Γ2;H2=1N−1h1+h2+h12 where hi; hij are the appropriate one- and two-particle operators. In passing we observe that the absolute value ...

Ecology lacks a holistic approach that can model phenomena across temporal and spatial scales, largely because of the challenges in modelling systems with a large number of interacting constituents. This hampers our understanding of complex ecosystems an
2, Yonghong Xie1,2, Li Jiang1,2, Xinsheng Chen1,2, Zhengmiao Deng1,2 & Baihan Pan1,2 In this paper, the effect of plant density, sediment type, and macrophyte fragment size on the fragment colonization ability of Myriophyllum spicatum was evaluated in an outdoor experiment....

Bulk density may be used as an indication of flow properties. The ratio of tapped density W/V50 to fluffy density (W/V0 g/ml) is known as the Hausner ratio. A good flow is indicated by a Hausner ratio greater than 1.25, and a poor flow may have a value of 1.5. ii. Angle of ...
Therefore, this study examined the effects of wetting conditions of the ground and the moist filling sand on the dry density, as determined using the sand-cone method in a laboratory. A small model of the ground containing in situ soil with different water content was used for simulating ...
