[1] Mires are key landscape elements at high latitudes and have certainly accumulated carbon during the Holocene, but their current carbon balance at the present time is very unclear. The major carbon flux is the land-atmosphere CO2 exchange and full-year data are still limited. Here we present data from 3 a (2001-2003) of continuous Eddy Covariance measurements at Degero Stormyr (64 degrees 11'N,
The measured net ecosystem exchange (NEE) of CO2 between the ecosystem and the atmosphere reflects the balance between gross CO2 assimilation [gross primary production (GPP)] and ecosystem respiration (R-eco). For understanding the mechanistic responses of ecosystem processes to environmental change it is important to separate these two flux components. Two approaches are conventionally used: (1)
The preferences of some woodland understorey species for ammonium and nitrate were investigated by measuring the potential nitrification (conversion of ammonium to nitrate) in the rhizosphere compared with the bulk soil. Less acid-tolerant species, which usually prefer nitrate or a mixture of ammonium and nitrate in hydroponic culture, should have a higher potential nitrification in the rhizospher
Western style diets and lifestyles are associated with increasing rates of obesity, diabetes and insulin resistance. Higher circulating insulin levels may modulate cell proliferation and apoptosis either directly or indirectly by increasing the bioactivity of IGF-I and decreasing the bioactivity of some of its binding proteins. The objective of this study was to determine the association of increa
The structural basis for the biological specificity of human cystatin C has been investigated. Cystatin C and other inhibitors belonging to family 2 of the cystatin superfamily interact reversibly with target peptidases, seemingly by independent affinity contributions from a wedge-shaped binding region built from two loop-forming inhibitor segments and a binding region corresponding to the N-termi
Endowed with diverse vegetation covers, the Middle Atlas Mountains receive substantial snowfall in winter, which contributes to plant hydration during the growing season. Using remotely-sensed imagery, this study aims to assess the trends in snow cover variations between 2000 and 2015, analyse the local influence of snowpack persistence on vegetation growth and evaluate the significance of this ef
Antibodies have for long time dominated the field of affinity proteins in example imaging and therapeutics, due to their high specificity and affinity. However, they have some major drawbacks such as high molecular weight, complex structure leading to instability and high production cost. Therefore, other types of affinity proteins have been engineered, for example the Affibody molecule which is a
Today, "the digital library" is the common way of describing a managed collection of information, with associated services, stored in digital formats and accessible over a network. Digital libraries have mainly been developed at research libraries, but during the last few years public libraries have started to offer similar services. The aim of this Master's thesis is to study how t
Title: Multi-Sided Platforms: Understanding their strengths and weaknesses Seminar date: 2014-05-22 Course: FEKN90 Företagsekonomi: Examensarbete på Civilekonomprogrammet (30 ECTS) Authors: Lucas Ehrenstråhle and Elin Mathies Supervisor: Magnus Johansson Five keywords: MSP, activities, resources, differentiation and platforms The purpose: is to investigate why small actors use multi-sided pl
The aim of our study is to understand how milk is represented online, more specifically on the Swedish web. We are interested in how information is being produced and distributed online, and also how networks of information are interconnected. We choose to examine milk because of the current controversies that have flourished online between a Swedish oat milk company and a Swedish milk organisatio
Jord i anslutning till skjutbanor innehåller ofta mycket höga blyhalter. Blyföroreningarna medför ett ökat upptag av bly i de växter som växer i jord från skjutbanor. Matväxter från skjutbanor kan kraftigt överskrida gränsvärdena för bly i livsmedel. För växterna medför blyexponeringen en omfördelning av biomassa, från rötter till skott. Bly är en tungmetall, och är giftig för såväl växter som djThis study investigates how lead content and bioavailability in soil affects growth and root/shoot ratio in three commonly cultivated species: wheat (Triticum turgidum), clover (Trifolium) and radish (Raphanus sativus). The study investigates the levels at which soil lead content contribute to toxic effects in plants, and when it may pose a risk to consumers. In addition, lead accumulation and the
Communication today is not something merely taking place face to face, technology such as the internet and social media channels have opened up for endless interactions taking place in the online world. User generated content in the form of online travel reviews come with many challenges and opportunities for organizations. User generated content has been shown to impact a travelers decision in al
The current conflict in Syria has resulted in a major refugee disaster. The lack of legal refugee routes to Europe is forcing refugees to hire smugglers to escape war in their homeland. They are often forced to pay large sums of money for the hazardous journey across the Mediterranean Sea and further through Europe. These journeys are often far stretched and not many are successful. Due to the war
Purpose: The purpose of this research is to contribute to logistics research arena in management practices using qualitative methods. Because previous research paradigm has been dominated by quantitative methods, where managerial work practices have been neglected or understated. Hence, by using the qualitative method the study can enrich the importance of manager work practice in logistics and br
The thesis uses hermeneutical analysis as well as reception and content analysis to interpret a current architectural debate. Within the architectural profession, there is a dogmatic style standard. Since the 1930s, modernism (also known as functionalism) has been the predominating style in architecture. This has led to an open resistance to architectural modernism brought before the public and to
Många processer i biologiska system utförs av maskinerier som är uppbyggda av molekyler av kolloidala dimensioner, d.v.s. i storleksordningen 1 μm till 1 nm, såsom proteiner. Dessa molekyler är ofta alldeles för komplexa till sin natur för att vi ska kunna förstå de “lagar” som styr hur de kommer samman för att bygga upp avancerade strukturer med biologisk funktion. I detta syfte behöver vi skapa The ability of microgels to adsorb to the interface of emulsion oil droplets has previously beenn reported in the literature.1 The resulting emulsions carry the thermoresponsiveness of the adsorbed microgels, and can be destabilized on demand by increasing the temperature above the volume phase transition temperature of the microgels. This thesis describes the synthesis and characterization of cro
