The change of water and sediment conditions in wandering channels has a great impact on the stability of river regime. The quantitative relationship between them is still unclear. The qualitative influence of water and sediment conditions on the river regime stability was analyzed by a model test. The response relationship between the upward or downward moving distance of the main stream zone and water and sediment conditions was quantitatively studied by using the measured water and sediment data and large-section data over the years. The results showed that when the upstream water and sediment inflow conditions change, the stability of a wandering channel with relatively stable river regime under the control of finite boundary will still change. When the river channel is at 1000 m3/s under the action of long-term small water, or silting thickness is about 0.53 m, the main stream next to the project moves upwards about 1170 m along the way. In the case of a large flood, such as 8000 m3/s, or scouring depth is about 0.39 m, the main stream next to the project moves downwards about 870 m along the way. The study provides a certain scientific basis for river regime stability and river flood control early warning, and provides a certain method reference for quantitative study of river regime evolution of other rivers at home and abroad.

Background: Since its discovery by Samuel Hahnemann over two centuries ago homoeopathy has gifted us many incredible cures, apart from many more cures of simple diseases. Moreover, it offers cheapest medicines. Still, it lacks wide acceptability. Its main reason is lack of scientific explanation, particularly for higher potencies -- Where is their medicinal value and how do they work? In trying to throw some light on such mysteries of homoeopathy this article arrives at a new and unifying concept of medicine. Method: Taking an earnest view of innumerable cures by homoeopathy many scientists from different fields are searching answers for the fundamental questions stated above. This article analyses logically sound and promising investigations. Results and Discussion: Indication is obtained that water structure holds the key to unlock the mystery of homoeopathy. Action mechanism of some main-stream medicines also supports the structural model. Together they lead to a generalized concept of medicine. Conclusion: The above analysis points to the conclusion that medicinal value of both homoeopathic and non-homoeopathic medicines lies in structures. Key words: generalized concept of medicine, structure holds the key.

Flooding in a sediment-laden floodplain is affected by riverine beach vegetation and the shape of a meandering compound channel. The laws of water and sediment exchange and the deposition distribution in beach troughs are very complex. These factors play a significant role in the formation and development of secondary suspended rivers, in the adjustment of the beach horizontal gradient, and even in the evolution of the flood control situation. In this study, we used a combination of experimental simulation and theoretical research to carry out a generalized model test of floodplain flooding evolution, analyzed the lateral distribution characteristics of sediment-laden flow and sediment factors in a meandering compound channel under the conditions of beach vegetation, and revealed the pros and cons of beach vegetation on the adjustment of the beach and channel siltation. The model test results of the flooding in the floodplain in the compound channel with meandering vegetation showed that the main stream was not only concentrated in the main channel but also appeared near the foot of the left and right bank levees and formed flood discharges along the embankment. As the riverine beach siltation was mainly concentrated at the riverine beach lip, the vegetation on the riverine beach had a significant effect on slowing down the flow velocity. Whether it was a row or full vegetation on both sides of the bank, this played an important role in the stability of the main channel. When there was no vegetation on the riverine beach, the main channel was easy to move. The arrangement of full vegetation on the riverine beach had a uniform effect on the velocity distribution of the riverine beach, which reduced the phenomenon of excessive velocity at the foot of the riverine beach and increased the velocity effect in the main channel. These results will provide a theoretical basis for the utilization of riverine beach areas and river management in the lower Yellow River and have a great significance for enriching the basic theory of water and sediment movement and promoting the integration of hydraulics, river dynamics, and ecology.

Yes to revitalisation of watercourses: (not) a question of loss of arable land (essay) Because of the reduced availability of soil resources, projects for flood control, renaturation or revitalisation of watercourses have been opposed on the grounds of their excessive consumption of land in general, and arable land in particular. By the way of the Water Protection Act, which has been revised and came into force in 2011, the Confederation obliges the cantons to prepare strategic plans for revitalisation of watercourses. In the Canton of Aargau, it is planned to revitalise 152 km of watercourses between 2015 and 2035, which will lead to the loss of 32 ha of arable land. This is about 1.5 ha per year, or 6% of the annual loss of arable land, which is about 24 ha per year. Three quarters of this total is lost to settlements. If one only considers losses outside built-up areas, in 2014, more than half was lost to buildings connected to agricultural activity. We can demonstrate, using the Siegfried maps of 1880, that more than 1,000 ha of former marsh and wetland are now arable land. The planned revitalisation of watercourses in Aargau over the next 20 years is equivalent to about 3% of the marsh and wetlands converted over the last 135 years. Revitalisation is compulsory, and the planned obligation to compensate the loss of arable land disregards the true situation: the major consumers of soil resources are settlements and, outside built-up areas, agriculture.

This book examines the role of the papacy and the crusade in the religious life of the late twelfth through late thirteenth centuries and beyond. Throughout the book, the contributors ask several important questions. Was Innocent III more theologian than lawyer-pope and how did his personal experience of earlier crusade campaigns inform his own vigorous promotion of the crusades? How did the outlook and policy of Honorius III differ from that of Innocent III in crucial areas including the promotion of multiple crusades (including the Fifth Crusade and the crusade of William of Montferrat) and how were both pope’s mindsets manifested in writings associated with them? What kind of men did Honorius III and Innocent III select to promote their plans for reform and crusade? How did the laity make their own mark on the crusade through participation in the peace movements which were so crucial to the stability in Europe essential for enabling crusaders to fulfill their vows abroad and through joining in the liturgical processions and prayers deemed essential for divine favor at home and abroad? Further essays explore the commemoration of crusade campaigns through the deliberate construction of physical and literary paths of remembrance. Yet while the enemy was often constructed in a deliberately polarizing fashion, did confessional differences really determine the way in which Latin crusaders and their descendants interacted with the Muslim world or did a more pragmatic position of ‘rough tolerance’ shape mundane activities including trade agreements and treaties?

Electoral stability has been viewed as an essential condition for the healthy functioning of representative democracy. However, there is little agreement in the literature about what shapes the stability of the electorate in general nor much attention paid to that of the Asian electorates in particular. We propose historical legacies, uniquely testable in Asia, as central determinants, but also test for conventional factors examined in other regions. By analyzing more than 150 elections in 19 post-WWII Asian democracies, we find that certain types of authoritarian (military or personalist) and colonial (non-British) legacies have a detrimental impact on the stabilization of the electorate, while some of the findings from other regions apply also to Asia. Our additional finding that such effects of historical legacies, particularly authoritarian interludes, are attenuated and cease to be significant with sufficient maturation of democracy, has important implications for the way party systems develop and democracies consolidate.

In this article it is demonstrated that an analysis of how building metaphorswere used in the Flemish Catholic discourse of the interwar years can offermore insight into the way a community of believers tries to establish a culturalcohesiveness. The main argument is that in a period of deep transformations,building metaphors could become "instruments" for Catholics whowanted to defend and promote a traditional dimension of their religion.Building metaphors allowed Catholics to stress the stability of their own ideology(the fundaments) and to formulate their own cultural project (buildingplan). By analysing such strategic use of building metaphors in artistic andphilosophical discourses, it can become possible to shed more light on the roleneo-thomism, a main philosophical current in interwar Flanders, played inartistic debates and more specific in discussions on the modernisation of religiousart.

The Impact

The authors of the work investigate one of the key areas of the Russian economy - the oil industry. It is hydrocarbons that account, on average, up to 40% of the Russian budget revenues. Oil revenues provide macroeconomic stability of the state, employment of the population in the oil and gas sector and related industries, as well as the stability of the ruble currency in the international market and prices for most types of products in the domestic market. The aim of the work is to study the possibilities of improving the current mechanisms for controlling price formation for key brands of hydrocarbons in order to increase the economic and energy security of the Russian Federation. The scientific study also analyzes the impact of the prices for Urals and Brent crude oil on the Russian ruble quotes against the US dollar and other world currencies. The correlation between the increasing of main oil brands value on the hydrocarbon market and strengthening of the Russian currency, as well as the filling the Reserve and other national funds, as one of the factors in the development of the Russian economy, is studied. The scientific basis of the research was Russian and foreign publications, state statistical materials, opinions and assessments of experts in the field, as well as the authors’ own developments. While studying the materials, the authors considered such indicators as: prices for “Brent”and “Urals” oil, their relationship and the reasons for the fall in prices for gasoline and hydrocarbon-derived materials, as well as the impact on the prices of goods in other economic sectors. The paper studies and selects the most effective responses to changes in the market environment in the context of nonstationary fuel prices.
