Spatial Pattern and Influencing Factors of Intangible Cultural Heritage of Music in Xiangxi, Central China

Intangible cultural heritage of music (ICHM) is an important part of intangible cultural heritage (ICH), and research on ICHM has extremely important theoretical value and practical significance. In this study, we aimed to analyze the spatial distribution characteristics of ICHMs and explore the main factors affecting their distribution in Xiangxi, Central China. Methods such as the nearest neighbor index, kernel density estimation, and buffer analysis were used in this study. The main conclusions are as follows: 1) the numbers of traditional music, traditional dance, traditional drama and quyi are 33, 34, 30 and 14, respectively, indicating that quyi is relatively lacking in Xiangxi; 2) the distribution of ICHMs in Xiangxi have spatial heterogeneity, and the main trend is agglomeration. The national ICHMs, provincial ICHMs and municipal ICHMs are mainly concentrated in the south, the west, and the central and northern regions, respectively. The high-density areas of traditional music and traditional dance are located in the south, of traditional drama in the west, and of quyi in the north. 3) The distribution of ICHMs is affected by four factors: namely rivers, topography, GDP and transportation. The 0-3 km buffer zone of the rivers, with 100% of national ICHMs, 83.33% of provincial ICHMs and 84.52% of municipal ICHMs, is the centralized distribution area of ICHMs. 100% of the national ICHMs, 94.44% of the provincial ICHMs and 91.67% of the municipal ICHMs are distributed in hilly (200-500 m) and low mountain areas (500-1000 m). Highways have the greatest impact on the distribution of ICHMs, followed by railways and ordinary roads. The economy has a significant positive impact on ICHM programs; the more developed the economy, the more ICHM projects. The results of this study can provide useful references for the theoretical research and practice management of ICH.

Numerical study of sediment transport in Thu-Bon estuary and coastal areas of Hoi-An City

The area of Cua-Dai estuary and the coastal areas of Hoi-An City have experienced complicated erosion and sedimentation in recent years. Along the coast of Hoi-An, erosion often occurs, whereas in the area of Cua-Dai River, there is an accretion phenomenon that obstructs the waterway navigation from Cua-Dai to Cu-Lao-Cham. Occurrence of sand dunes in the offshore location of Cua-Dai has been recorded at a number of times in recent years. Studying the process of bed morphological change due to the sediment transport in the Thu-Bon river and the influence of monsoons in the area allows to explain the above phenomenon thus an in-depth study to propose appropriate solutions. This study used the numerical model Telemac which combines the hydro-morphodynamic and wave modules. The simulation results show that the main trend of coastal currents caused by tides and waves tends to go southward, leading to coastal erosion especially in the northeast monsoon season as well as sedimentation in the estuarine area. In addition, the model also shows the crucial role of waves in shoreline erosion, with the degree of erosion in the north coast near Cua-Dai being more severe than the southern coast, through the formation of local eddy flow on the north coast.

Geodemographic Dynamics of Crimean Population: Main Trends and Factors of Post-Soviet Period

The article examines the geodemographic dynamics of the Crimea in the post-Soviet period: changes in the population of the peninsula, its centers and territories; changeable ratio of natural and migration components, and shifts in the settlement system. In the dynamics of the processes under analysis, four stages are distinguished: three of them relate to the Ukrainian period of the Crimea’s development, and the last one it is the Russian stage which begins in 2014. Until the mid-1990s (the first stage), the population of the peninsula continues to grow, despite the natural decline and increased outflow to Russia. The main reason for this is the large-scale re-emigration of Crimean Tatars to the peninsula, most of whom settle in the interior of the Crimea. The next stage (late 1990s – the middle of the 2000s) is associated with a significant depopulation of the region, primarily due to a high natural population decline. The third stage (the second half of the 2000s – the beginning of the 2010s), at which the depopulation is replaced by a minimal increase in the population of the peninsula, is associated with an improvement of the indicators of its natural reproduction and a certain increase in the migration influx. The features of the Russian development stage are set by two multi-component processes. Migration activity is determined by the consequences of the transition of the Crimea to Russia. Meanwhile in the natural reproduction, a central role is played by a small generation of the 1990s entering into the reproductive age, with such consequences as a rapid decline in the birth rate and an increase in natural loss. The result of these processes is a certain stabilization of the population of the Crimea. The situation in which the natural decline is offset by the migration influx is likely to continue in the nearest future and in the medium term period (until 2030–2035). The main trend in the spatial distribution of the demographic potential of the Crimea in the last 15–20 years is a gradual increase in the proportion of the population settled on the coast and in the coastal zone 15–20 km wide.

Analysis of Micelle Formation and Adsorption Layers of Binary Mixtures of Sulphate Soap Components

Currently, the main trend of the pulp and paper industry development is bio-refining. It is based on integrated and deep processing of wood raw materials to obtain products with higher value added and reduced amount of waste. One of the high priority tasks of bio-refining is improvement of technology of by-product (sulphate soap) extraction from spent liquor with an increase in the yield and quality of the resulting product and a decrease in the level of environmental pollution. The complexity and energy intensity of sulphate soap extraction from spent liquor depends on many factors, including the species used for wood cooking, composition of extractives, the method of wood preparation for delignification, etc. Sulphate soap is a multicomponent emulsion with a predominant content of resin and fatty acids, small amount of unsaponifiable substances and an admixture of lignin, which is mainly extracted from waste liquior by settling. The low degree of its extraction is associated with the absence of systematical data on the mutual influence of the sulphate soap components. In this work, the patterns of intermolecular interaction of the individual components of the by-product (sulphate soap) are found. For this purposes the critical concentration of micelle formation (CCM) and surface tension depression of surface-active sodium oleate and sodium abietate and their mixtures of varying compositions were determined by the methods of tensiometry and conductometry. A detailed analysis of its mixed micelles and adsorption layers was carried out using the Rubin–Rosen pseudophase model. The interaction mechanisms of components in mixtures are explained. The impact on the composition of micelles and adsorption layers of the more surface-active sodium oleate was detected in mixed solutions. A maximum synergistic effect of micelle formation was observed in mixtures with a predominant content of sodium abietate. Analysis of experimental data and the result of sulphate soap modeling allow substantiating the complexity of its extraction from waste liquor after wood cooking with the presence of hardwood over 30 %, which is explained by the reduced content of resin acids in black liquor.

The Economics Spectrum Drives Root Trait Strategies in Mediterranean Vegetation

Extensive research efforts are devoted to understand fine root trait variation and to confirm the existence of a belowground root economics spectrum (RES) from acquisitive to conservative root strategies that is analogous to the leaf economics spectrum (LES). The economics spectrum implies a trade-off between maximizing resource acquisition and productivity or maximizing resource conservation and longevity; however, this theoretical framework still remains controversial for roots. We compiled a database of 320 Mediterranean woody and herbaceous species to critically assess if the classic economics spectrum theory can be broadly extended to roots. Fine roots displayed a wide diversity of forms and properties in Mediterranean vegetation, resulting in a multidimensional trait space. The main trend of variation in this multidimensional root space is analogous to the main axis of LES, while the second trend of variation is partially determined by an anatomical trade-off between tissue density and diameter. Specific root area (SRA) is the main trait explaining species distribution along the RES, regardless of the selected traits. We advocate for the need to unify and standardize the criteria and approaches used within the economics framework between leaves and roots, for the sake of theoretical consistency.
