Populärvetenskaplig sammanfattning I Arktis finns det enorma lager av kol som ligger i och under permafrosten, vilket är frusen mark som inte har tinat på två år. Mycket tyder på att delar av dessa lager är känsliga för en temperaturökning och idag sker en pågående uppvärmning. Arktis värms snabbare än övriga jorden på grund av att vit reflekterande is och snö smälter, vilket resulterar i att hav The permafrost area in the Arctic region contains vast carbon stocks within and beneath the permafrost, which is frozen ground that has not thawed in two years. These carbon stocks are sensitive to ongoing global warming. When the white and reflective snow and ice melts, the remaining land and sea surfaces absorb more shortwave radiation and get warmer. Heat transport to the Arctic will also incre

This paper investigates the effects of population age structure and economic growth on the household saving rate in China and examines whether life cycle hypothesis (LCH) holds in the country like China, where LCH may be less applicable. By applying two popular time series econometric techniques (cointegration technique and vector error correction model), the author examines the long-run convergen

Populärvetenskaplig sammanfattning Världens skogar spelar en viktig roll i den globala kolcykeln. Med den ökade nivån av CO2-koncentrationen i atmosfären, orsakad av bränning av fossila bränslen och avskogning, så är det viktigt att analysera skogens roll som global kolsänka. Denna uppsats analyserar den boreala skogen och den tropiska skogen genom att undersöka hur mycket kol som tas upp och var The world’s forest biomes have an important role in the global carbon cycle. With an increasing level of atmospheric CO2 concentration, mainly due to the burning of fossil fuel and deforestation, it is important to analyze the significance of the forests biomes as carbon sinks. This review analyses the boreal forest and the tropical forest by investigating the amount of carbon taken up and where m

This paper addresses the questions whether the provisions of the freedom of secondary establishment require the origin and host states provide identical treatment with regard to subsidiary (resident for tax purposes) and permanent establishment (non-resident for tax purposes) in all respects. The paper highlights the fundamentals of the comparability analysis as well as the basics of the subsequen

My study is based on Göran Hägglunds statement that kristdemokraterna no longer support the proposal to remove the sterilisation requirement for transsexuals in the law of establishing sex in certain cases. The purpose of my study was to examine how different actors were debating about the statement to keep sterilisation requirements in an argumentation analysis. I did this by looking at the argum

Populärvetenskaplig sammanfattning Arktis har under de senaste årtiondena upplevt betydande uppvärmning och enligt prognoser förväntas ytterligare höjningar av både lufttemperatur och nederbörd under det kommande århundradet. Det förändrade klimatet har haft omfattande konsekvenser för permafrosten (ständigt frusen mark) som format och kraftigt präglar stora delar av det arktiska landskapet. Med öThe Arctic region has experienced significant warming in the past decades and according to predictions further increases in air temperatures and precipitation will occur during the 21st century. Recent changes in climate have had widespread implications for the permafrost around the Arctic. Shorter periods of snow covering the Arctic regions significantly reduce the average annual albedo which dra

The present study had two primary objectives; one, to examine whether general self-efficacy was correlated with procrastination; and two, to investigate if a specific motivation approach could be linked to the tendency to procrastinate. It was hypothesized that self-efficacy would be negatively correlated with procrastination, and that avoidance-oriented motivation and mastery-oriented motivation

Due to the change in climate the design flow for Bergeforsen dam, located at the Indalsälven river mouth, is being revised from 2300 m3/s to more than 3000 m3/s. The dam needs to be upgraded with a new gated spillway and repaired in order to increase the safety of the dam. Concerns have been raised about the altered flow conditions that will occur downstream of the dam in connection with that the

En analys av hur svenska bostadsägares räntekänslighet varierar beroende på i vilket län hushållet är bosatt i respektive vilken åldersgrupp man tillhör och hushållstyp man är ägare till.

A lattice model for fibril formation on the basis of general peptide interactions is presented. Fibrils are well-structured protein aggregates and a key phenomenon in many diseases, among them Alzheimer. We study the model’s equilibrium and kinetic properties using Wang-Landau sampling and a Metropolis Monte Carlo algorithm with cluster moves. The peptides are shown to form ordered fibrilar aggreg

Abstrakt: Användarinvolvering är resurskrävande och påverkas av många faktorer. Resultaten (värde och nyttan) av användarinvolvering är svår att mäta, vilket gör att företag inte vill riskera att investera i onödan. Men om användarna inte involveras i utvecklingen finns risken att ett projekt misslyckas. Någonstans måste man överväga och besluta om hur eller om man ska involvera användarna i ett u

Föräldraskapet är en unik och krävande erfarenhet för varje kvinna. I postpartum perioden kan kvinnan drabbas av både fysiska och psykologiska faktorer som kan påverka den sexuella hälsan på ett både positivt och negativt sätt. Studiens syfte var att belysa kvinnans upplevelse av sin sexuella hälsa efter vaginal förlossning. Studiens design var kvalitativ med induktiv ansats där datainsamlingen be

This thesis takes its inspiration from two statements of objections given by the Commission of the European Union and compares it with the equivalent legal development in the US. The objections hint to the EU judiciary’s stance towards standard setting organizations and conduct exclusive to standard setting processes. Focus will be given to the development on EU competition law under article 102 T

Populärvetenskaplig sammanfattning Klimatet i region Sahel varierar på en årlig och decennielång basis. Under slutet av 1900-talet har den utsätts för en period av markant torka. Mellan 1960 och 1990 nådde nederbörden nivåer av bara 40 % av genomsnittet. På grund av detta skattas perioden en av de makantaste klimatiska fenomen i hela världen under 1900-talet. Torkan har orsakat stora konsekvenser The Sahel is a region of large interannual and interdecadal climatic variability. In the late 20th century it experienced a period of pronounced drought that lasted from the late 1960 to the early 1990s, where precipitation values reached only about 40% of the long-term mean. This is why this period counts among one of the most striking climatic phenomena worldwide in the 20th century. The consequ

In this thesis, sustainability is explored as it relates to local government in Perth, Western Australia. Firstly the conversation around the concept of sustainability is explored by looking at key policies, and governmental initiatives in the area, as well as the leaders and focus areas that have shaped the dialogue of sustainability in Perth. Secondly the major projects that are being undertaken

Today the energy question and the ambitions to reduce energy usage are in focus in both the media and at government level. In Sweden today, newly built houses use little energy for heating. This makes the energy for home appliances more influencial in total. Household owners have a great influence on how the energy within the household is used. In order to minimize electrical consumption, the hous

Vid stora krissituationer – nationella som internationella – organiserar svenska medier ofta telefonväkterier, där allmänheten får ringa in och ställa frågor direkt till experter och ansvariga. Vad betyder dessa telefonväkterier för förhållandet mellan samhälle och medborgare, mellan experter och lekmän? Genom att analysera tre telefonväkterier(Tjernobyl 1986, SR, Fukushima 2011, SVT, och Eyjafjal

Many organizations today are striving to gain competitive advantages and work efficiently in the demanding market through the adoption of ICT (Information and Communications Technology) solutions such as ERP (Enterprise Resource Management), CRM (Customer Relationship Management), and Business Analytics Systems. However, these Information Technology (IT) solutions can be quite expensive for small
