Popular Abstract in Swedish Kvantprickar är objekt där elektroner är instängda i en mycket liten volym (av storleksordningen 100 nanometer i varje riktning). I den här avhandlingen har vi studerat kvantprickar definierade i nanotrådar av halvledarmaterial. Nanotrådarna kan vara flera mikrometer långa men samtidigt mycket tunna (mindre än 100 nanometer eller 0,1 mikrometer). Vi har skapat kvantpriThis thesis focuses on electrical transport in semiconductor InAs nanowires grown by chemical beam epitaxy. Initially, transport length scales of homogeneous InAs n-type nanowires are characterized by low-temperature magnetoconductance measurements. The measurements show phase-coherent conductivity corrections. By fitting the data, we find the nanowire mean-free path to be 50 nm and the phase-cohe

Orientation experiments were performed with first-year snow buntings (Plectrophenax nivalis) during their autumn migration in a natural near-vertical geomagnetic field approximately 400 km away from the magnetic north pole. Migratory orientation of snow buntings was recorded using two different techniques: orientation cage tests and freeflight release experiments. Experiments were performed under

The red admiral (Vanessa atalanta) is a migratory butterfly that can be found in North America, North Africa, Europe and some parts of Asia. In Europe the main part of the population spend winter in the Mediterranean region and the following spring leave this area to breed further to the north. At least one new generation is then produced in the summer region before they return to the south again

Popular Abstract in Swedish Låg temperatur begränsar i stor utsträckning överlevnad och expansion av vegetation. Under senare år har samverkan mellan låg temperatur och hög instrålning, som leder till försämrad fotosynteseffektivitet, rönt stor uppmärksamhet. I denna avhandling tillämpas nya metoder för att relatera rumsliga variationer i temperatur och instrålning till fotosynteseffektivitet ochLow temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. In this thesis, novel approaches are applied for relating the spatial variability in low temperature and irradiance to photosynthetic performance and growth of tree seedlings

Popular Abstract in Swedish För att en multicellulär organism som männinskan ska kunna fungera måste celldelningen strikt kontrolleras. Protein som reglerar celldelning på cellulär nivå kallas för "tillväxtfaktorer". Vi har studerat ett sådant protein som kallas för transforming growth factor-beta (TGF-b). Namnet TGF-b kommer sig utav att detta protein kan transformera (omvandla) epiteliala njurceTransforming growth factor-beta (TGF-b) is a well-characterised growth regulatory factor, which acts on most cell types. This thesis has focused on the regulatory roles of TGF-b on normal lymphocytes. One interesting finding is that TGF-b acts both costimulatory and inhibitory on T-lymphocytes. The costimulatory effect depends on the presence of monocytes and is mediated by these cells. Furthermor

Design is an activity aimed at solving an unsolved problem or improving an existing solution. In the area of societal safety, there are many activities that could be classified as design activities. For example when different actors are implementing measures to mitigate certain risk scenarios or when they are considering actions that could improve their capability to respond to various crises. We

Accelerator programs that support enterprises in their early stages are growing in numbers, acknowledged by many as an important organizational form for achieving economic growth. However, focusing solely on economic growth has proven to be detrimental for the environment and not enough to solve the challenges of our current social systems. As a response, accelerators and social enterprises that f

The understanding of the link between the water, sanitation and hygiene (WASH) sector and gender has been extensively researched and is widely accepted as foundational for achieving safe and equal provision of WASH-facilities. Interventions aimed at improvements in the sector are common in low- and middle-income countries, however, there is a limited number of approaches for measuring their outcom

Den här uppsatsen är inspirerad av det kollektivavtal som ingicks av Sveriges Hamnar och Svenska Hamnarbetarförbundet våren 2019. Sveriges Hamnar hade redan ett kollektivavtal sedan tidigare. Under förhandlingarna föreslogs ett avtalsvillkor som innebar att enbart Svenska Transportarbetareförbundet, som hade träffat det första avtalet, skulle ha rätt att ingå i förhandlingar om lokala avtal. KlausThis paper is inspired by the collective agreement that was concluded between Ports of Sweden and the Swedish Dockworkers Union in the spring of 2019. Ports of Sweden was already bound by another collective agreement. During the negotiations a contractual condition was proposed which expressed that only the Swedish Transport Workers’ Union, the party of the prior agreement, would have the right to

As concentrations of measured CO2 in the atmosphere reach a record high it is important to attempt all possible efforts to reduce the emissions of greenhouse gases (GHG) in all aspects of industry. The fishing sector contributes 15% of total GHG emission in Iceland, with the majority originating from fishing vessels using fossil fuel. The relationship between catching locations of Atlantic Mackere

"In the shadow of global rivalry and maritime trade. Swedish sailors in Moroccan captivity, 1754-1763". In the attempt by the Swedish government to expand its commercial trade in the Mediterranean in the 18th century several of its trading vessels were captured by Moroccan corsairs. By initially employing maritime diplomacy and sending naval expeditions to the area they sought to protect

Populärvetenskaplig sammanfattning: Dagens landskap bär på många spår från den senaste istiden. Det kan röra sig om räfflor på berghällar som bildats när inlandsisen med sten och grus glidit fram över en berggrundsyta, eller olika lager av lösa jordarter som transporterats och avlagrats av inlandsisen. Geologer använder dessa spår när de försöker rekonstruera nedisningsförloppet. Genom detaljstudiA narrow gorge in deep weathered bedrock has been uncovered during quarrying at Romeleåsen horst, Skåne, southern Sweden. The gorge was filled up with a homogeneous diamicton deposited directly on the weathered surfaces, but also on vertical walls of glacially abraded bedrock. The filling sediments and the contact to the bedrock were investigated in purpose to interpret sedimentary processes and d

Populärvetenskaplig sammanfattning: Barsebäcksmossen, som är belägen vid kusten i sydvästra Skåne, är i dag en kärrmark, men den har tidigare varit en brackvattenlagun av Littorina-havet (ett tidigare stadium i Östersjöns utveckling, som kännetecknas av en betydlig högre salthalt än i nutid). Jag har studerat Barebäcksmossens utveckling genom att analysera pollen, frukter och frön, samt skal av The past Littorina lagoon at Barsebäck, SW Skåne, has earlier been studied by Nilsson (1935) and Digerfeldt (1972, 1975). The objective of the present study was to find complementary sedimentary evidence of the minor transgressions and regressions during the lagoon development, which were reconstructed by Digerfeldt (1975). The study was based on pollen and macrofossil analyses of some sediment c

Stanford, ett mindre samhälle 150 km väst om Kapstaden, har under de senaste åren sett en ökad turism och utveckling, vilket har medfört ett ökat behov av färskvatten. I dagsläget används en naturlig källa som täkt för kommunens vattenbehov, men källans hållbara vattenavgivningsförmåga på 33 000 m3/månad är otillräcklig och en kompletterande täkt är nödvändig. Stanfordakvifären består av två formaThis study focuses on the Stanford Aquifer which is located in the Overberg region in the Western Cape of South Africa. The ’Eye’, a captured spring, is used as source for potable water for the local municipality and extraction have in recent years exceeded the sustainable yield of 33 000 m3/month and a supplementary source is therefore needed. The aim of this study is to develop a conceptual mode

Issue: The majority of arable land that exists today is already occupied while the population around the world is constantly increasing. New cultivable areas must be explored and developed. Is the construction of greenhouses on existing rooftops in urban environments possible, and how can this benefit a city like Malmö? Purpose: The purpose of this project is to display how a greenhouse may be con

Corporate Social Responsibility (CSR) has emerged to cover the company’s responsibility in their participation in solving social problems. Research has shown that CSR planning and implementation vary significantly between developed and developing countries. Previous literature on CSR were mainly dominated by Western nuances, and they overlooked the implication of socio-cultural aspects in the deve

The purpose of this essay is to shed light upon the ecumenical work that has been done between the Church of Sweden and the Mission Covenant Church of Sweden. The recent years of work have led to a recommendation for a certain degree of fellowship to be established between those churches. This proposal as well as other documents are analysed in the essay from an ecclesio-logical point of view, to

When referring to non-present entities, speakers and signers can select from a range of different strategies to create expressions that range from extremely concise to highly elaborate. This design of referring expressions is based partly on the availability of contextual information that can aid addressee understanding. In the small signing community of Providence Island, signers' heavy reliance

Objective: This study aimed to evaluate the 9-month cost and health-related quality of life (HRQOL) outcomes of resistance versus viral load testing strategies to manage virological failure in low-middle income countries. Methods: We analyzed secondary outcomes from the REVAMP clinical trial: a pragmatic, open label, parallel-arm randomized trial investigating resistance versus viral load testing

South Korea is well known for its development miracle: the nation has managed to develop from the state of extreme poverty to the World´s 12th largest economies in a period of five decades. However, the negative consequences and side effects of this rapid growth, and issues of the contemporary Korean society has been less discussed, especially from the perspective of the Korean youth. The millenni
