We report a 40-year history of SF6 atmospheric mole fractions measured at the Advanced Global Atmospheric Gases Experiment (AGAGE) monitoring sites, combined with archived air samples, to determine emission estimates from 1978 to 2018. Previously we reported a global emission rate of 7.3±0.6 Gg yr−1 in 2008 and over the past decade emissions have continued to increase by about 24 % to 9.04±0.35 Gg
This dissertation studies the historical relation between the Muslim minority and the non-Muslim majority in Yunnan with a combined method: historical criticism supplemented by ethnological interpretation. This relation manifests in history dynamic and dialectical characteristics: concord and conflict. Concord can be found in the stable and balanced periods in the relevant socio-cultural aspects o
A key step in lipolytic activation of adipocytes is the translocation of hormone-sensitive lipase (HSL) from the cytosol to the surface of the lipid storage droplet. Adipocytes from perilipin-null animals have an elevated basal rate of lipolysis compared with adipocytes from Wild-type mice, but fail to respond maximally to lipolytic stimuli. This defect is downstream of the p-adrenergic receptor-a
Fragmentation, as one of the most distinct characteristics of agricultural landscapes worldwide, has resulted in a diversity of ecological consequences. It remains as a gap in the literature on how provisioning service changes in association with agricultural fragmentation and land use management. Addressing such a gap at a national level should provide essential insights for policymakers. This pa
Recent evidence shows that rising wage inequality in industrialized countries can partially be attributed to trade integration. However, it is unclear what the mechanisms behind this relationship are. Previous explanations pointed towards the displacement of mid-wage manufacturing workers as a response to rising imports. But for Germany it has been shown that rising exports likewise create manufac
Meteoric beryllium-10 (10Be) is commonly used as a proxy of landscape dynamics (erosion and sedimentation rates) and soil development. Soil represents the first-stage reservoir of meteoric 10Be, and variability in the concentration of the isotope in soils may be affected by soil properties and atmospheric deposition. Although many investigations have targeted this issue, there are still problems i
This paper addresses the question why socio-technical transitions follow similar trajectories in various parts of the world, even though the relevant material preconditions and institutional contexts vary greatly between different regions and countries. It takes a critical stance on the implicit methodological nationalism in transition studies' socio-technical regime concept and proposes an altern
Purpose - The purpose is to investigate how a retailer identifies critical network actors and gains their support when entering an emerging market. and to examine the role of a firm's relationships with different types of actors on the new market. Design/methodology/approach - The study is of an exploratory nature, and based on an inductive and qualitative research method. A case study of IKEA's e
This study explores the process of global sourcing through a case of the Swedish furnishing retailer IKEA from an interaction perspective. With a point of departure in the streams of existing research on global sourcing and the internationalization process of firms through networks, a research question is proposed concerning supply network interactions as an influence in the global sourcing proces
In this thesis, the focus is on the trade relations between Estonia and selected Asian countries based on their importance, aiming to identify the current trade flows, changes within them over time and the reasons behind these changes. Furthermore, the comparative advantage of Estonia in relation to those countries should be revealed. The main research question is how the trade flows have changed
In this thesis the possibility of using mussels as a sensor for contaminants in drinking water intakes was evaluated. Oxygen consumption, heart rate and valve movement was measured upon exposure to oil, caffeine (a marker for waste water) and copper. Valve movement was measured both by time lapse recordings of the mussels and by attaching strain gauges to their shells. One species of freshwater mu
In this paper, four major parameters of fresh water production from saline sources are discussed. The parameters are desalination technology type, water sources input type, energy sources and productions cost per cubic meter. Five different types of desalination technology are presented and bench-marked for long-term use. RO and MSF are dominant technologies. Six different input water sources are
