Making use of the finite difference method, the radon concentration distribution in the overburden above active faults is calculated and modeled. The active fault zone parameters, such as the depth and the width of the fault zone, and the value of radon concentration, can be inverted from the measured radon concentration curve. These realize quantitative interpretation for radon concentration anomalies. The inversion results are in good agreement with the actual fault zone parameters.展开更多

The author considers music as areflection of worldview and religion. For this purpose the author uses a method of comparison of a mythological picture of the world and properties of musical language. An important element linking the two areas is vertical. In mythology, this is turning the world on several floors in which the world of people occupies the middle one. At the level of music--it is the vertical of overtone sound row. The initial timbre ideal of this tradition are th esounds of throat singing which are associated with the vertical of the universe and consciousness used as an important formative structure of the World Model. In the article the author considers a materialization of musical consciousness in musical instruments. For this purpose, eight instruments under different names are selected andpresented in musical cultures of people. This allows the author to create the card of geographical distribution of tengri consciousness.展开更多

Results showed that the majority of soil nematodes were presented in the 0–20 cm soil layers in CW treatments, followed by in the 20–40 cm and 40–60 cm layers in GW treatments. Plant-feeding nametodes were the most abundant trophic groups in each treatment, where GW(91.0%) > TW(88.1%) > CW(53.5%). Generic richness(GR) was lower in the TW(16) than that in GW(23) and CW(25). The combination of enrichment index(EI) and structure index(SI) showed that the soil food web in GW was more structured, and those in TW was stressed, while the enrichment soil food web was presented in the CW treatment. Several ecological indices which reflected soil community structure, diversity, Shannon-Weaver diversity(H′), Evenness(J′), Richness(GR) and modified maturity index(MMI) were found to be effective for assessing the response of soil namatode communities to soil of saline wetland reclamation. Furthermore, saline wetland reclamation also exerted great influence on the soil physical and chemical properties(p H, Electric conductivity(EC), Total organic carbon(TOC), Total nitrogen(Total-N) and Nitrate Nitrogen(N-NO3–)). These results indicated that the wetland reclamation had significantly effects on soil nematode community structure and soil properties in this study.展开更多
