Deglaciation of the Caucasus Mountains, Russia/Georgia, in the 21st century observed with ASTER satellite imagery and aerial photograpy

Changes in the map area of 498 glaciers located on the Main Caucasus ridge (MCR) and on Mt. Elbrus in the Greater Caucasus Mountains (Russia and Georgia) were assessed using multispectral ASTER and panchromatic Landsat imagery with 15 m spatial resolution in 1999/2001 and 2010/2012. Changes in recession rates of glacier snouts between 1987–2001 and 2001–2010 were investigated using aerial photography and ASTER imagery for a sub-sample of 44 glaciers. In total, glacier area decreased by 4.7 ± 2.1% or 19.2 ± 8.7 km2 from 407.3 ± 5.4 km2 to 388.1 ± 5.2 km2. Glaciers located in the central and western MCR lost 13.4 ± 7.3 km2 (4.7 ± 2.5%) in total or 8.5 km2 (5.0 ± 2.4%) and 4.9 km2 (4.1 ± 2.7%) respectively. Glaciers on Mt. Elbrus, although located at higher elevations, lost 5.8 ± 1.4 km2 (4.9 ± 1.2%) of their total area. The recession rates of valley glacier termini increased between 1987–2000/01 and 2000/01–2010 (2000 for the western MCR and 2001 for the central MCR and Mt.~Elbrus) from 3.8 ± 0.8, 3.2 ± 0.9 and 8.3 ± 0.8 m yr−1 to 11.9 ± 1.1, 8.7 ± 1.1 and 14.1 ± 1.1 m yr−1 in the central and western MCR and on Mt. Elbrus respectively. The highest rate of increase in glacier termini retreat was registered on the southern slope of the central MCR where it has tripled. A positive trend in summer temperatures forced glacier recession, and strong positive temperature anomalies in 1998, 2006, and 2010 contributed to the enhanced loss of ice. An increase in accumulation season precipitation observed in the northern MCR since the mid-1980s has not compensated for the effects of summer warming while the negative precipitation anomalies, observed on the southern slope of the central MCR in the 1990s, resulted in stronger glacier wastage.

Narratives of grassroots innovations: a comparison of voluntary simplicity and the transition movement in Italy

Grassroots innovations (GI) are promising examples of deliberate transformation of socio-technical systems towards resilience and sustainability. However, evidence is needed on the factors that limit or enable their success. This paper set out to study how GI use narratives to empower innovation in the face of incumbent socio-technical regimes. Institutional documents were comparatively analyzed to assess how the narratives influence the structure, form of action and external interactions of two Italian grassroots networks, Bilanci di Giustizia and Transition Network Italy. The paper finds an internal consistency between narratives and strategies for each of the two networks. The paper also highlights core similarities, but also significant differences in the ethical basis of the two narratives, and in the organizations and strategies. Such differences determine different forms of innovation empowerment and expose the niche to different potentials to transform incumbent regimes, or to the risk of being co-opted by them.

Thermal Study in Solid State of Zn(II)-Diclofenac Complex: Behavior Kinetic of the Dehydration, Transition Phase and Thermal Decomposition

The dehydration, thermal decomposition and transition phase stage of Zn(II)-diclofenac compound were studied by simultaneous TG-DTA and DSC techniques. The TG and DSC curves of this compound were obtained with the mass of sample of 2 and 5 mg. Additionally, DSC curves were carried out in opened and closed alpha-alumina pans under static and nitrogen atmosphere. The DTA and DSC curves show that this compound possesses exothermic transition phase between 170-180 degrees C, which it is irreversible (monotropic reaction) The kinetics study of this transition phase stage was evaluated by DSC under non-isothermal conditions. The obtained data were evaluated with the isoconversional method, where the values of activation energy (E(a) / kJ mol(-1)) was plotted in function of the conversion degree (alpha). The results show that due to mass sample, different activation energies were obtained From these curves a tendency can be seen where the plots maintain the same profile for closed lids and almost run parallel to each other.

Trust and Social Networks in a Changing Europe.

This project set out to investigate the effects of the recent massive social transitions in Eastern Europe on the everyday social lives of the inhabitants of three very different nations: Georgia, Russia and Hungary. It focused in particular on the availability and nature of the support networks available to three different segments of each of the societies (manual workers, students and entrepreneurs) and the impact of network participation on psychological and physical well-being. The group set four specific questions to investigate: the part played by individual psychological beliefs in the formation and maintenance of social networks and the consequent formation of trusting relations; the implication of the size and quality of these networks for mental health; the nature of the social groups inhabited by the respondents and the implication of their work schedule and daily routines on the maintenance of a social and family life; and an analysis of how cultures vary in their social networks and intimacy. Three different methods were used to examine social support and its implications: structured questionnaires, semi-structured short interviews and a media analysis of newspaper materials. The questionnaires were administered to 150 participants in each country, equally divided between students studying full time, manual workers employed in factories, and business people (small kiosk owners, whose work and life style differs considerably from that of the manual workers). The questionnaires investigated various predictors of social support including the locus of control, relationship beliefs, individualism-collectivism and egalitarianism, demographic variables (age, gender and occupation), social support, both in general and in relation to significant events that have occurred since the transition from communism. Those with an internal locus of control were more likely to report a higher level of social support, as were collectivists, while age too was a significant predictor, with younger respondents enjoying higher levels of support, regardless of the measures of support employed. Respondents across the cultures referred to a decline of social support and the group also found a direct correlation between social support and mental health outcomes. All 450 respondents were interviewed on their general responses to changes in their lives since the fall of communism and the effects of their work lives on their social lives and the home environment. The interviews revealed considerable variations in the way in which work-life offered opportunities for a broader social life and also provided a hindrance to the development of fulfilling relationships. Many of the work experiences discussed were culture specific, with work having a particularly negative impact on the social life of Russian entrepreneurs but being seen much more positively in Georgia. This may reflect the nature of support offered in a society as overall support levels were lowest in Russia, meaning that social support may be of particular importance there. The way in cultural values and norms about personal relationships are transmitted in a culture is a critical issue for social psychologists and the group examined newspaper articles in those newspapers read by the respondents in each of the three countries. These revealed a number of different themes. The concept of a divided society and its implications for personal relationships was clearest in Russian and Hungary, where widely-read newspapers dwelt on the contrast between "new Russians/Hungarians" and the older, poorer ones and extended considerable sympathy to those suffering from neglect in institutions. Magyar Nemzet, a paper widely read by Hungarian students reflects the generally more pessimistic tone about personal relationships in Russia and Hungary and gave a particularly detailed analysis of the implications this holds for human relations in a modern society. In Georgia, however, the tone of the newspapers is more positive, stressing greater social cohesion. Part of this cohesion is framed in the context of religion, with the church appealing to a broader egalitarianism, whereas in less egalitarian Hungary appeals by the Church are centred more on the nuclear family and its need for expansion in both size and influence. The division between the sexes was another prominent issue in Hungary and Russia, while the theme of generational conflict also emerged in Hungarian and Georgian papers, although with some understanding of "young people today". The team's original expectation that the different newspapers read by the different groups of respondents would present differing images of personal relationships was not fulfilled, as despite variations in style, they found little clear "ideological targeting" of any particular readership. They conclude that the vast majority of respondents recognised that the social transition from communism has had a significant impact on the well-being of social relationships and that this is a pertinent issue for all segments of society. While the group see the data collected as a source to be worked on for some time in the future, their initial impressions include the following. Social support is clearly an important concern across all three countries. All respondents (including the students) lament the time taken up by their heavy work schedules and value their social networks and family ties in particular. The level of social support differs across the countries investigated, with Georgian apparently enjoying significantly higher levels of social support. The analysis produced an image of a relatively cohesive and egalitarian society in which even the group most often seen as distant from the general population, business people, is supported by a strong social network. In contrast, the support networks available to the Russian respondents seem particularly weak and reflect a general sense of division and alienation within the culture as a whole. The implications of low levels of social support may vary across countries. While Russians reported the lowest level of mental health problems, the link between social support and mental health may be strongest in that country. In contrast, in Hungary it is the link between fatalism and mental health problems which is particularly strong, while in Georgia the strongest correlation was between mental health and marital quality, emphasising the significance of the marital relationship in that country.

A Comparative Study on Higher Education Acts in Bulgaria, Hungary, Poland, Romania and Russia

The original aim of this project was to describe and analyse the higher education acts in force in five Central and Eastern European countries at present, trying to understand the dependence of higher education on the historical traditions, national peculiarities and all-European tendencies. The description and comparison of the main aspects of higher education was supplemented by a study of the possibilities of transferring experience in the field between the five countries and possible solutions to implementing foreign structural and functional models. Questions covered included the role of the state in the management of higher education, the structures of the higher education systems and the organisation of institutions, academic autonomy and the classifications of academic teaching staff, the main trends in the recent development of research, academic degrees, the accreditation of higher education institutions, and the financing of higher education. Popov found that it was almost impossible to understand the dependence of higher education on historical traditions and national peculiarities purely through a study of the relevant legislation. Education traditions in these countries have twice been broken, once with the start of communism (1917 in Russia and 1944-45 in Bulgaria, Hungary, Poland and Romania) and for a second time at the beginning of the 1990s. The most recent higher education acts in all five countries studied have abandoned many of their historical and national traditions, following instead all-European trends as determined by Western Europe, and the project included a study of the dependence on these trends. There were also difficulties in comparing some aspects of higher education as it depended on how far a given aspect has different or common features in the different countries and to what extent the application is comparable. While many possible areas for transferring experience between the five countries were identified, Popov concentrated on those where he felt that there was a real practical possibility of application in view of national academic differences. He concluded by defining some of the challenges facing each country in the field of higher education and by making some predictions as to the developments in the different countries.

Molecular interaction between perthiolated [beta]-cyclodextrin (CD) and the guests molecules adamantaneacetic acid (AD) and ferroceneacetic acid (FC); and the effect of the interaction on the electron transition of CD anchored particles

The molecular interactions between the host molecule, perthiolated beta-cyclodextrin (CD), and the guest molecules, adamantaneacetic acid (AD) and ferroceneacetic acid (FC), have been inestigated theoretically in both the gas and aqueous phases. The major computations have been carried out at the theoretical levels, RHF/6-31G and B3LYP/6- 31G. MP2 electronic energies were also computed based at the geometries optimized by both the RHF and B3LYP methods in the gas phase to establish a better estimate of the correlation effect. The solvent phase computations were completed at the RHF/6-31G and B3LYP/6-31G levels using the PCM model. The most stable structures optimized in gas phase by both the RHF and B3LYP methods were used for the computations in solution. A method to systematically manipulate the relative position and orientation between the interacting molecules is proposed. In the gas phase, six trials with different host-guest relative positions and orientations were completed successfully with the B3LYP method for both the CD-AD and CD-FC complexes. Only four trials were completed with RHF method. In the gas phase, the best results from the RHF method gives for the association Gibbs free energy (ΔG°) values equal to -32.21kj/mol for CD-AD and -25.73kj/mol for CD-FC. And the best results from the B3LYP method have ΔG° equal to -47.57kj/mol for CD-AD and -41.09kj/mol for CD-FC. The MP2 correction significantly lowers ΔG° based on the geometries from both methods. For the RHF structure, the MP2 computations lowered ΔG° to -60.64kj/mol for CD-AD and -54.10 for CD-FC. For the structure from the B3LYP method, it was reduced to -59.87 kj/mol for CD-AD and -54.84 kj/mol for CDFC. The RHF solvent phase calculations yielded following results: ΔG°(aq) equals 107.2kj/mol for CD-AD and 111.4kj/mol for CD-FC. Compared with the results from the RHF method, the B3LYP method provided clearly better solvent phase results with ΔG° (aq) equal to 38.64kj/mol for CD-AD and 39.61kj/mol for CD-FC. These results qualitatively explain the experimental observations. However quantitatively they are in poor agreement with the experimental values available in the literature and those recently published by Liu et al. And the reason is believed to be omission of hydrophobic contribution to the association. Determining the global geometrical minima for these very large systems was very difficult and computationally time consuming, but after a very thorough search, these were identified. A relevant result of this search is that when the complexes, CD-AD and CD-FC, are formed, the AD and FC molecules are only partially embedded inside the CD cavity. The totally embedded complexes were found to have significantly higher energies. The semiempirical method, ZINDO, was employed to investigate the effect of complexation on the first electronic excitation of CD anchored to a metal nano-particle. The computational results revealed that after complexation to FC, the transition intensity declines to about 25% of the original value, and after complexation with AD, the intensity drops almost 50%. The tighter binding and transition intensity of CD-AD qualitatively agrees with the experimental result that the addition of AD to a solution of CD and FC restores the fluorescence of CD that was quenched by the addition of FC. A method to evaluate the “hydrophobic force” effect is proposed for future work.

Sedimentation and mineral analysis on sediment cores from the Lena Delta

Core and outcrop analysis from Lena mouth deposits have been used to reconstruct the Late Quaternary sedimentation history of the Lena Delta. Sediment properties (heavy mineral composition, grain size characteristics, organic carbon content) and age determinations (14C AMS and IR-OSL) are applied to discriminate the main sedimentary units of the three major geomorphic terraces, which form the delta. The development of the terraces is controlled by complex interactions among the following four factors: (1) Channel migration. According to the distribution of 14C and IR-OSL age determinations of Lena mouth sediments, the major river runoff direction shifted from the west during marine isotope stages 5-3 (third terrace deposits) towards the northwest during marine isotope stage 2 and transition to stage 1 (second terrace), to the northeast and east during the Holocene (first terrace deposits). (2) Eustasy. Sea level rise from Last Glacial lowstand to the modern sea level position, reached at 6-5 ka BP, resulted in back-filling and flooding of the palaeovalleys. (3) Neotectonics. The extension of the Arctic Mid-Ocean Ridge into the Laptev Sea shelf acted as a halfgraben, showing dilatation movements with different subsidence rates. From the continent side, differential neotectonics with uplift and transpression in the Siberian coast ridges are active. Both likely have influenced river behavior by providing sites for preservation, with uplift, in particular, allowing accumulation of deposits in the second terrace in the western sector. The actual delta setting comprises only the eastern sector of the Lena Delta. (4) Peat formation. Polygenetic formation of ice-rich peaty sand (''Ice Complex'') was most extensive (7-11 m in thickness) in the southern part of the delta area between 43 and 14 ka BP (third terrace deposits). In recent times, alluvial peat (5-6 m in thickness) is accumulated on top of the deltaic sequences in the eastern sector (first terrace).

The Pro-Western Turn in Russia's Foreign Policy: Causes, Consequences and Prospects. OSW Point of View, September 2002

From Europe and Poland's point of view, one of the most important recent developments in international politics was the re-orientation of Russia's foreign policy. This paper aims to answer three important questions relating to this issue: 4. When and why did the "pro-Western turn" in the Russian Federation's policy take place? 5. Has it been profitable for Russia? 6. What goals will the Russian policy pursue in the future? An analysis of the last two years in Russia's foreign policy leads to the several conclusions, including those: 5. Clearly, the Russian leaders realise that in the longer term, Russia - in its desire for more influence in the world - will not be able to survive as an independent pole of power in international politics and it will have to join forces with the West (most likely, the European Union). 6. September 11 was not the cause of Russia's pro-Western turn, but rather a catalyst that put the process which started when Vladimir Putin took his office in sharp focus. 7. In the nearest future, this new direction of Russia's foreign policy seems not be challenged by internal opposition in Russia. 8. The "pro-Western turn" proved to be beneficial for Russia, although: d. Russia has not become a strategic ally of the US e. There has been no breakthrough in the relations between Russia and the European Union, and Moscow has not gained any real influence on NATO's important decisions. f. Russia has not become a major decision-maker of international politics. 5. Russia's closing to the West is in Poland's and Europe's interest.

Rebalancing the EU-Russia-Ukraine gas relationship. Bruegel Policy Contribution ISSUE 2014/15, DECEMBER 2014

The October 2014 agreement on gas supplies between Russia, Ukraine and the European Union did not resolve the Ukraine-Russia conflict over gas. The differences between parties in terms of objectives, growing mistrust and legacy issues make it unlikely that a long-term stable arrangement will be achieved without further escalation. Without EU pressure and support, Ukraine is likely to enter a new unfavourable gas arrangement with Russia, which could have repercussions beyond the energy sector. Key highlights: To reduce prices and increase the security of imports, the EU as a bloc should redefine its gas relationship with Russia and Ukraine and overcome the diverging interests of EU member states on second-order issues. Implementation of a joint strategy rests on enforcement of EU competition and gas market rules, a strengthened role for the Energy Community and the establishment of a market-based instrument for supply security. For Ukraine, the EU should serve as an anchor for comprehensive gas sector reform. Contingent on Ukraine’s reform efforts, EU financial and technical assistance, the enabling of reverse flows from the EU to Ukraine and pressure on Gazprom, should eventually enable Ukraine to obtain a sustainable gas-supply contract with Russia. This should make a sustainable and mutually beneficial Russia-Ukraine-EU gas relationship possible. However, during the transition, the EU should be prepared for possible frictions.

Ukraine and Russia: a hindered rapprochement. OSW Commentary No. 44, 2010-12-15

The policy of rapprochement with Russia that President Victor Yanukovych and his entourage had been actively promoting in the first months of his presidency has slowed down notably. One of the reasons for this lowered pace is that current talks between Russia and Ukraine concern the spheres in which Kyiv is not ready to make concessions to Russia. Despite numerous top-level meetings, recent months have failed to bring a breakthrough in energy issues of key importance. First of all, no compromise was reached in gas issues where the divergence of interests is particularly large and where Ukraine has adopted a tough stance to negotiate the best conditions possible. Even though some agreements were signed during the October session of the inter-governmental committee presided over by the prime ministers (the agreement on linking the two states’ aircraft production and on the joint construction of a nuclear fuel production plant), these resulted from prior agreements. Economic negotiations will continue in the coming months but the observed deadlock is not likely to be broken any time soon. The results of these talks are likely to reflect the interests of both Russia and Ukraine, as well as the competition among Ukrainian business groups, some of which opt for closer cooperation with their Eastern neighbour. Ukraine’s consent to send oil to Belarus along the Odessa-Brody pipeline shows that the government in Kyiv is ready to engage in projects they consider profitable, even those that run counter to Russian interests. Ukraine’s adoption of this stance may trigger irritation in Moscow and lead to a cooling in bilateral relations.

Russia's best ally: The situation of the Russian oil sector and forecast for its future. OSW Study 39/2012

Oil is a strategic raw material for Russia and one of fundamental significance for the functioning of the state and its future. Taxes on oil production and exports are the most important source of state budget revenues which guarantee Russia maintains its political and economic stability. Russia is building its international position on the basis of its vast raw material and energy potential. While a great number of various publications have been devoted to Russian gas and Gazprom, surprisingly little research has been done into the present condition and possible future developments of the Russian oil sector, despite the fact that oil has and will have a much greater impact than gas on the functioning and the future of Russia. The main objective of this text is to describe the present situation of the Russian oil sector, its problems and the challenges it is posing, as well as the government’s policy towards this key branch of the Russian economy. This will be an introduction to an attempt to answer to the questions about the possible future production and the export levels of Russian oil, also broken down into the European and Asian directions.

The China-Russia trade relationship and its impact on Europe. Breugel Working Paper Issue 4, 2016

This paper analyses empirically how increasingly close trade relations between China and Russia might affect the European Union (EU). We show that EU countries are complementary to Russia on the Chinese market. However, Chinese exports are increasingly relevant substitutes for EU exports on the Russian market. This means that an increase in China-Russia economic cooperation should have a negative impact on European exports. We simulate a scenario in which trade tariffs between Russia and China are eliminated, which is found to reduce EU exports to Russia. Finally, a more granular approach to the question analyses which sectors in Europe will be more affected by the increasing economic links between China and Russia, and finds that electronic machinery, equipment and machinery, and nuclear reactors will be particularly affected. Such findings obviously show quickly China is moving up the ladder in terms of export structure and how strategically important it is for Europe to continue upgrading its industry to compete at the highest level of that ladder.

The Great Slump of 2008–9 and Ukraine's integration with the European Union

For a number of years following the Orange revolution of 2004, Ukraine aspired to join the European Union. Although full integration was never a short-term prospect, European integration, through the Association Agreement and the Deep and Comprehensive Free Trade Area, offers considerable benefits to Ukraine. However, the country was severely affected by the Great Slump of 2008–9 in the global economy, and this profoundly negative experience has shaped Ukrainian domestic and foreign policy in the subsequent period, putting paid to aspirations to EU membership and influencing the Ukrainian government's decision to seek a closer relationship with Russia immediately following the presidential election of 2010. Nevertheless, closer relations with Russia should not adversely affect Ukraine's efforts at EU integration.
