Diet at medieval Alytus, Lithuania: Stable carbon and nitrogen isotope analysis of bone and dentin collagen

Whitmore, Katie 01 January 2014 (has links)
The Baltic region was a vibrant center of power and economic prosperity in medieval Europe; Lithuania in particular. Until now, little stable isotopic analysis has been utilized to assess diet in this region during this time period. The aim of this study was to undertake a preliminary assessment of the composition of diet at late medieval Alytus (late 14th to early 18th centuries) from bone (N=35) and dentin (N=38) collagen samples. The stable carbon isotopic data suggest a diet primarily comprised of C3 plants such as barley, rye, wheat, and flax, and animals consuming C3 plants. The stable nitrogen isotopic data indicate the use of aquatic resources, and reflects the protein portion of the diet as including mainly terrestrial non-legumes. There are no significant differences in the pattern of resource consumption between juvenile males and females. There is a significant difference between adult males and adult females; the more depleted bone collagen ?15N values indicates that adult females were consuming less protein resources, or protein resources of a lower trophic level, compared to their male counterparts. This difference could also be affected by physiological factors such as pregnancy or disease. A difference between juvenile and adult stable nitrogen isotope values might indicate latter weaning of juvenile males, the incorporation of more terrestrial or aquatic protein into juvenile male diet, the incorporation of less terrestrial or aquatic protein into adult female diet, or a combination of the three.

NATO Enlargement: Poland, The Baltics, Ukraine and Georgia

Radcliffe, Christopher M. 01 January 2018 (has links)
Over the past two decades, the North Atlantic Treaty Organization (NATO) has enlarged several times to include a number of new countries. The first two case studies that are analyzed within this paper include key countries that were added in the 1999 and 2004 rounds of NATO enlargement: Poland, Lithuania, Latvia, and Estonia. The third case study takes a closer look at two countries, Ukraine and Georgia, that sought to become members of NATO but were denied Membership Action Plans (MAPs) because of Russian discontent and military intervention. It is questionable if Russia will use military force to disrupt the territorial sovereignty of future prospective NATO candidate countries. This paper aims to identify the trend between countries seeking NATO membership and Russian intervention within these countries. Poland joined NATO in 1999, and much to Moscow’s dislike, NATO’s borders expanded farther into Eastern Europe. The Baltic States, Latvia, Estonia, and Lithuania, joined NATO in 2004, pushing the NATO border right against Russia’s northwestern front. This gave western alliances the ability to host military operations through NATO on the Russian border. It is apparent that Moscow has done everything in its power to prevent more countries that share a border with Russia from joining NATO. Only three months after the Bucharest Summit in 2008, Russia invaded two territories in Georgia. After the pro-Russian president in Ukraine was ousted in 2014, Russia invaded Eastern Ukraine and annexed the Crimean Peninsula. In order to be offered a MAP, the candidate country must have complete sovereignty over its territory. By invading key points within both Georgia and Ukraine, Russia was delaying their ability to become members of the security alliance. It is apparent that there is a connection between increased NATO collaboration with countries that border Russia, and military action taken upon those countries by Russia.

National minorities as peace-builders? How three Baltic Germans responded to the First World War

Housden, Martyn 17 February 2018 (has links)
Yes / Many members of Europe’s national minorities had particularly terrible experiences during the First World War. This article examines how three ethnic German minority activists from the Baltic region responded to those dreadful years by, subsequently, presenting themselves as peace campaigners promoting a novel model for multi-ethnic society. They promoted ideas such as the ‘a-national state’ and ‘cultural autonomy’ at both national and international levels, not least in the hope of influencing the League of Nations. To what extent should they be accepted as early peacebuilders? / British Academy

Is blue mussel farming a potential mitigation tool to combat eutrophication in the Baltic Sea? A synthesis based on stakeholder interviews

Zilinskaite, Emilija January 2019 (has links)
The Baltic Sea is the most polluted sea in the world. Its hydrological conditions and ongoing eutrophication are a high threat for marine biodiversity and ecosystems. Additionally, eutrophication has negative effects on the wellbeing of countries and their societies in the Baltic Sea Region (BSR). Actions to mitigate eutrophication in the Baltic Sea have been implemented through on-land measures in the last 40 years. Although the improvement in the marine environment is notable, it happens very slowly. In order to combat eutrophication, there is a need for a combination of on-land and in-situ measures. In this study, blue mussel farming practices are presented as one of the in-situ measures to combat eutrophication in the Baltic Sea. Blue mussel farming has been implemented in Sweden since the 1980s and has potential to not only mitigate the amounts of nutrients that accumulate in the sea but also brings a circular approach to resource use. In this study, stakeholders from four different sectors that are closely related to blue mussel farming practices and Baltic Sea issues have been interviewed with the aim of making a comprehensive analysis of stakeholder perceptions of blue mussel farming practices in the BSR. Interviewed stakeholders represent four different sectors - academia, entrepreneurs, municipalities and NGOs. A comprehensive analysis of stakeholders’ perceptions on blue mussel farming practises from environmental, social and economic perspective is presented. All interviewed stakeholders are actors in Sweden and represent Swedish perspective on blue mussel farming activities. Potential causes for different perceptions across sectors are discussed.

Thirty conferences of Baltic musicologists: some recollections and results

Humal, Mart January 1997 (has links)
Looking back to the thirty years of Baltic musicologists'' conferences we can distinguish their two main functions, the fulfilling of which has taken place inseparably from one another. First of all, they have had an unvaluable social importance preserving and reinforching our Baltic identity and solidarity. At the same time they habe been one of the main audience before which we have during tens of years acquainted one another with the best achievements of our musicological thought.

Air-Sea Fluxes of CO2 : Analysis Methods and Impact on Carbon Budget

Norman, Maria January 2013 (has links)
Carbon dioxide (CO2) is an important greenhouse gas, and the atmospheric concentration of CO2 has increased by more than 100 ppm since prior to the industrial revolution.  The global oceans are considered an important sink of atmospheric CO2, since approximately one third of the anthropogenic emissions are absorbed by the oceans. To be able to model the global carbon cycle and the future climate, it is important to have knowledge of the processes controlling the air-sea exchange of CO2. In this thesis, measurements as well as a model is used in order to increase the knowledge of the exchange processes. The air-sea flux of CO2 is estimated from high frequency measurements using three methods; one empirical method, and two methods with a solid theoretical foundation. The methods are modified to be applicable for various atmospheric stratifications, and the agreement between methods is good in average. A new parameterization of the transfer velocity (the rate of transfer across the air-sea interface), is implemented in a Baltic Sea model. The new parameterization includes also the mechanism of water-side convection. The impact of including the new parameterization is relatively small due to feedback processes in the model. The new parameterization is however more representative for flux calculations using in-situ measurement or remote sensing products. When removing the feedback to the model, the monthly average flux increases by up to 20% in some months, compared to when water-side convection is not included. The Baltic Sea carbon budget was estimated using the Baltic Sea model, and the Baltic Sea was found to be a net sink of CO2. This is consistent with some previous studies, while contradictory to others. The dissimilarity between studies indicates the difficulty in estimating the carbon budget mainly due to variations of the CO2 uptake/release in time and space. Local variations not captured by the model, such as coastal upwelling, give uncertainties to the model. Coastal upwelling can alter the uptake/release of CO2 in a region by up to 250%. If upwelling would be included in the model, the Baltic Sea might be considered a smaller sink of CO2.

Severská spolupráce. Její proměny ve druhé polovině 20. století a současná podoba / Nordic Cooperation. Its Transformation in the Second Half of the 20th Century and its Current Shape

Viktorová, Iva January 2008 (has links)
Diploma thesis "Nordic Cooperation. Its Transformation in the Second Half of the 20th Century and Its Current Shape" deals with the Nordic cooperation among Denmark, Finland, Iceland, Norway and Sweden from the second half of the 20th century with the focus on the period from the 1990s till 2008. At the beginning, there is an introduction to the history of cooperation in Scandinavia till the 1990s and a description of two main institutions of the Nordic cooperation: the Nordic Council and the Nordic Council of Ministers. The main chapter analyses the Nordic cooperation from the 1990s, it focuses on areas and intensity of the cooperation and describes concrete programmes, projects, institutions, targets and results of the cooperation. The thesis also deals with the question of the impact of the three Baltic States involvement in the Nordic cooperation in the 1990s. The answer is that the internal Nordic cooperation has been developing very intensively - it was demonstrated by the analysis of the Nordic cooperation in the 1990s in the main chapter - without any affecting of the Baltic States involvement in the main. On the contrary, the Baltic States involvement has brouhgt the external opportunity for the Nordic countries to integrate into the cooperation in the Baltic Sea region.

Characterization of the structure, stratigraphy and CO2 storage potential of the Swedish sector of the Baltic and Hanö Bay basins using seismic reflection methods

Sopher, Daniel January 2016 (has links)
An extensive multi-channel seismic dataset acquired between 1970 and 1990 by Oljeprospektering AB (OPAB) has recently been made available by the Geological Survey of Sweden (SGU). This thesis summarizes four papers, which utilize this largely unpublished dataset to improve our understanding of the geology and CO2 storage capacity of the Baltic and Hanö Bay basins in southern Sweden. A range of new processing workflows were developed, which typically provide an improvement in the final stacked seismic image, when compared to the result obtained with the original processing. A method was developed to convert scanned images of seismic sections into SEGY files, which allows large amounts of the OPAB dataset to be imported and interpreted using modern software. A new method for joint imaging of multiples and primaries was developed, which is shown to provide an improvement in signal to noise for some of the seismic lines within the OPAB dataset. For the first time, five interpreted regional seismic profiles detailing the entire sedimentary sequence within these basins, are presented. Depth structure maps detailing the Outer Hanö Bay area and the deeper parts of the Baltic Basin were also generated. Although the overall structure and stratigraphy of the basins inferred from the reprocessed OPAB dataset are consistent with previous studies, some new observations have been made, which improve the understanding of the tectonic history of these basins and provide insight into how the depositional environments have changed throughout time. The effective CO2 storage potential within structural and stratigraphic traps is assessed for the Cambrian Viklau, När and Faludden sandstone reservoirs. A probabilistic methodology is utilized, which allows a robust assessment of the storage capacity as well as the associated uncertainty. The most favourable storage option in the Swedish sector of the Baltic Basin is assessed to be the Faludden stratigraphic trap, which is estimated to have a mid case (P50) storage capacity of 3390 Mt in the deeper part of the basin, where CO2 can be stored in a supercritical phase.
