Populärvetenskaplig sammanfattning: Kvävecykeln är betydelsefull i ett globalt perspektiv eftersom den inverkar både på klimatet och olika ekosystemsprocesser. Den kan med andra ord beskrivas som kvävets kretslopp som beskriver de kemiska, fysiologiska, biologiska och geologiska processerna som sker i naturen. Dikväveoxid är en stark växthusgas och inverkar på klimatet då den precis som koldioxid The nitrogen cycle is included in the biogeochemical cycles that connect all the organisms in one giant ecosystem, the biosphere. The nitrogen cycle is important both in a global perspective where the greenhouse gas N2O affects the climate and in a local perspective where it controls different processes in ecosystems. The availability of nutrients also have a great influence on all aquatic ecosyst

Eye tracking, the direct measurement of eye movements, is a method suitable for studying cognitive processes in detail, and has been used for studies of both human and nonhuman subjects. It provides an opportunity to study human and animals under similar conditions, using the same apparatus, and can therefore be a useful tool in comparative studies. Unfortunately this possibility is seldom utilize

Abstract The aim of this paper was to find out whether Swedes with a good knowledge of the Italian language were capable of laughing and reacting at the jokes of the Italian comedian Antonio Albanese through his fictional character, Cetto La Qualunque. The focusing point was to determine which linguistic features alongside non-linguistic features (i.e., body language and mimic above all), would

Syftet med denna uppsats var att genom en explorativ undersökning titta efter skillnader mellan den serbiska och svenska kulturen i Sverige och Serbien i en arbetsrelaterad kontext och på vilket sätt/hur dessa i så fall uppenbarar sig. En kvalitativ, emergent design användes för undersökningen, där 12 respondenter deltog. Studien har en fenomenologisk ansats, där självrapporter använts. Resultatet

Icelandic authorities implemented capital controls in October 2008, in a response to the global financial crisis and to prevent outflow of foreign reserves. This was done to protect the Icelandic krona from depreciating and to gain monetary autonomy. However, the operational activity of the pension funds in Iceland has been affected by this policy change, as the funds have been missing out on fore

The aim of this thesis is to study the role of house prices in influencing the effect of monetary policy shocks on private consumption in five EMU member states during the period 1995Q1-2010Q4. The role of house prices may be increasingly important in effecting private consumption possibilities due to the deregulations of mortgage markets in many countries in recent years and the increasing availa

Syfte: Vi undersöker vilka barriärer teknologstudenter upplever mot entreprenörskap och hur universitetet och individerna kan påverka dessa. Metod: I denna studie har vi använt oss av kvalitativ metod. Det empiriska underlaget har samlats in via semistrukturerade intervjuer med 15 teknologstudenter vid LTH. Teoretiska perspektiv: Vi har huvudsakligen utgått från artiklar och studier utförda i fler

The purpose of this report is to examine whether there is any connection between the multi-storey wooden buildings, industrial construction and environmental impact. In the early 1960’s prefabricated parts were used to build “Miljonprogrammet”. This led to the streamlining of the construction process but the houses were often ill-suited for those who would live in them. Traditional building became

In today’s society more and more work is carried out with the help of dif- ferent computer systems. To benefit from the data, integration between the systems is needed. Saab has developed a solution to the problem, by the name WISE. With a modular design costs can be minimized, because a new integration does not necessarily require new software, but can be achieved with configuration of an existin

Gränser mellan vegetationszoner fascinerar genom att på ett tydligt sätt påminna oss om sambanden som finns mellan det som lever och dess miljö. En av de mest påtagliga gränserna är den alpina trädgränsen, där fjällbjörkskogen gradvis övergår till kalfjäll. Den karga miljön som utgör kalfjället är starkt kopplat med temperatur och klimatförändringens ökade temperatur har medfört förändringar i träAerial photo interpretation shows a recent densification of trees has been occurring between 1960 and 2009 in the mountain birch (Betula pubescens ssp. czerepanovii) forest of the treeline ecotone in northern Swedish mountains. The correlation between treeline position and annual temperature is commonly accepted and advancing treelines are considered to be a useful indicator for monitoring climate

Hälften av Afrikas befolkning - mer än 300 miljoner människor - hotas idag av markförstöring och ökenspridning. De flesta forskare är överens om att markförstöring orsakas av mänsklig aktivitet som avsiktligt eller oavsiktligt rubbar balansen i redan känsliga ekosystem. Namibia det torraste landet söder om Sahara, vilket följaktligen gjort att landet är mycket utsatt för ökenspridning och markförsHalf of Africa’s population - more than 300 million people - is threatened by land degradation. In general, land degradation is initiated when people intentionally or accidentally disturb the balance in a already fragile ecosystem. Poor management practices such as overgrazing, puts pressure on land already close to exceed the limits of sustainability. Besides suffering from overgrazing issues, Na

Agroforestry är ett jordbrukssystem där odling av grödor kombineras med träd på samma jordbruksytor. Då den stadigt minskande markbördigheten ses som den främsta begränsningen till ökade skördar, är det nödvändigt för en hållbar matproduktion att näringsämnen som tas upp av grödor från marken, eller försvinner på grund av erosion och urlakning, fylls på. Många länder i Afrika har i flera årtiondenAgroforestry is an agricultural system where crop farming is combined with trees on the same land. The steadily decreasing soil fertility is considered to be the primary constraint to increased crop yields, and it is vital to replenish the nutrients lost by plant uptake or removal by erosion and leaching for a sustainable food production. Several African countries have for tens of years received f

I många utvecklingsländer globalt är svält och undernäring bland befolkningen ett stort problem. Två av de mest drabbade områdena är Afrika söder om Sahara och östra Afrika, och i framtiden förväntas problemet förvärras av global uppvärmning och kraftig befolkningsökning. Temperaturhöjning och förändrad nederbörd kommer att minska produktionen i området, och med detta tillgången av mat samt övrig Food insecurity is a major problem in the developing countries of the world, where sub- Saharan and eastern Africa is some of the most affected areas. With rapid population growth and lack of means to adapt to a changing climate, the region is in the danger zone for famine. The aim of this paper is to examine the food situation in Ethiopia today, and how the climate change is predicted to affect t

Denna kandidatuppsats är en litteraturstudie som behandlar jökulhlaups och deras tillhörande landformer samt deras inverkan på landskapet. Jökulhlaup är den isländska termen för störtfloder från glaciärer och används internationellt för att beskriva detta fenomen. Vattnet som skapar dessa störtfloder kan ha många olika ursprung, såsom kraftig nederbörd, snabb avsmältning av glaciäris, tömning av eGlacial outburst floods also known as jökulhlaups are important features connected with glaciers globally. They may induce catastrophic floods as well as new landforms. This review describes and synthesizes jökulhlaup trigger mechanisms as well as associated landforms and landscape impacts of jökulhlaups with a special focus on Skeiðarársandur, south Iceland, and the 1996 jökulhlaup. Important sou

The purpose of this study was to examine how gambling addiction is understood by those active in the field, the consequences of gambling addiction and treatment available for gambling addiction in Sweden. We also wanted to examine if gambling addiction could be seen as a social problem or not depending on our theoretical basis. Our main issues were: 1 How do active within the field of gambling add

The biotechnology patent per million inhabitants has a leading position worldwide. This thesis aims to research the key factors that ensure and promote companies’ growth in biotech industry compared with other industries in Denmark. The research results

När rovfåglar flyttar använder de antingen glid- och kretsflykt eller en kombination av glid och aktiv flykt. Energikonsumtionen vid aktiv flykt ökar snabbt med ökad kroppsvikt och används därför oftast av mindre rovfågelarter så som falkar, sparvhökar och kärrhökar. Glid- och kretsflykt används till mycket stor utsträckning av de större och tyngre arterna som vråkar, glador och örnar, som då är bRaptors migrate by using either soaring and gliding flight or a combination of gliding and powered flight. The energy consumption when using powered flight increases rapidly with body mass and is therefore mainly used by the smaller raptors, such as Falcons, Sparrowhawks and Harriers. Soaring and gliding flight are mainly used by the larger raptors such as Buzzards, Kites and Eagles. When using so

Wars have, basically, always existed. Hand in hand with all wars there is always some kind of justification. As our communities and wars develop so the criteria for a just war develop with them. The aim of this thesis is to examine how the development of the just war has occurred. This will be done through a choice of various historical events, in which I will analyze the discussion about the just

The aim of this essay is to study bronze casting during the Scandinavian bronze age through the artefact crucibles. The main question is; how many castings has it been possible to do with the crucibles found at Broåsen Sweden before they had to be discarded? Other investigations of bronze casting have stated that 1-10 castings is the maximum amount of usage for a ceramic crucible, thereby making i

This essay studies how democracy is formulated in the steering documents in the Swedish school system. It suggests that the program is a dynamic interventionistic program. Democracy is analysed with Lundquist´s model that present the democratic values in substantial values- equality, freedom, solidarity, justice and process values- openness, mutual reciprocity, responsibility. The conclusion is th
