Vid byggnation av vägar och järnvägar i Sverige idag används nästan uteslutande ändliga resurser som bergkross eller naturgrus som ballastmaterial. Det är av stort intresse att undersöka om till exempel återvunnet material och restprodukter från industrier skulle kunna användas i stället. För detta ändamål byggdes en testväg i november 2024 inne på en avfallsanläggning i Helsingborg. Vägen, som foDuring construction of roads and railways in Sweden today, mainly finite resources such as crushed rock or natural gravel, are being used as ballast material. It is of great interest to investigate whether, for instance, recycled materials and residual products from industries could be used instead. For this purpose, a test road was constructed in November of 2024 in a waste facility in Helsingbor

The purpose of this investigation is to explore and highlight the role of the Third World within a human rights framework during the era of decolonization. More specifically the investigation analyzes in what ways states from the Third World used human rights to argue for the abolishment of colonialism within the context of debates in the 15th session of the UN General Assembly in 1960 and in rela

Den här studien ämnade att undersöka huruvida olika musikgenrer; blues , klassisk musik och rockmusik, samt utan musik (kontrollgrupp), påverkar prestation i matematik. 52 personer deltog i studien och de blev alla tilldelade en av de fyra musikgenrerna genom en mellangruppsdesign. Studien bestod av två test. Första testet var ett standardiserat matematiktest bestående av 12 frågor (refereras till

Naturlig selektion i vilda skalbaggspopulationer Naturlig selektion är en nyckelfaktor för evolutionen. Även om vi vet att mängden variation i egenskaper (fenotyper) ger råmaterial för selektion och om den är genetisk påverkar evolutionens hastighet, har vi fortfarande mycket att lära om hur naturlig selektion påverkar specifika egenskaper över tid. I min examensuppsats undersökte jag hur naturliNatural selection is an important force behind evolution. It is well known that phenotypic variation provides opportunity for evolution, but research into how selection acts on specific traits over time is lacking. In this thesis, I studied how selection acts upon the shape and body size of the beetle Cassida viridis. Across three populations, I measured size (length and area), shape, and lifespan

Theoretically the relation between returns and idiosyncratic volatility should be non-existent or positive. Many empirical studies confirm this but Ang, Hodrick, Xing and Zhang (2006) contest the conventional view and find a negative relationship for a sample of U.S. firms. I contribute to the field by investigating the relation for a sample of U.S. mutual funds. The sample consist of a total of 1

The aim of this study was to examine how professionals on residential care for unaccompanied children worked with the youths needs. Due to the increase of refugees coming to Sweden and specially unaccompanied children it has become one of our present time most important political questions. In order to examine how the professionals are working with the unaccompanied children’s needs we believed th

En viktig komponent i vårt moderna samhälle är plaster och användandet av detta material ökar. Plaster skapas av komponenter som extraheras från petroleum, ett icke-förnybart fossilt bränsle. För en hållbar framtid måste användandet av petroleum minska. Alternativ till petroleum-baserade plaster är bio-plaster. Bioraffinaderier använder idag mindre än 20 % av biomassan för etanolproduktion, överskBioplastics are a promising alternative for petroleum-based plastics that today is on high demand in our contemporary lifestyles. They are made from biopolymers such as polyhydroxyalkanoates (PHAs). Producing biopolymers from waste material feedstock using microbes increases profitability and environmental benefits as well as sustainability for biorefineries. Saccharomyces cerevisiae is a robust m

En klinisk pilotstudie med kvantitativ ansats har undersökt data från patienter diagnostiserade med depression, dystymi, ångeststörning eller bipolär sjukdom och deras barn och närstående utifrån skattad psykisk hälsa och familjefunktion. Data på baslinjenivå inhämtades från deltagare rekryterade i en pågående utvärderingsstudie av Axberg, Priebe och Grip (2013) som syftar till att utvärdera de prA clinical pilot study with a quantitative approach has examined data from patients diagnosed with depression, dysthymia, anxiety disorder or bipolar disorder, and their children and partners based on self-reported mental health and family functioning. Baseline data was collected from participants enrolled in an ongoing evaluation study by Axberg, Priebe and Grip (2013), which aims to evaluate the

This essay investigates the online L2 processing of restricted collocations and figurative idioms. Earlier research has shown there to be a difference in how these word combinations are processed depending on a variety of factors. In this study a self-paced reading experiment is administered to 15 second language learners of English (L1 Swedish) where their reading time is measured by DMDX softwar

In a globalized world with increasing international trade, it is highly important to accurately determine environmental impacts resulting from pollution embodied in trade. This study examines carbon dioxide (CO2) emissions embodied in international trade of the United Kingdom from a consumption perspective, rather than the more conventional production side, during the period 1995-2009. The analysi

In the summer of 2014, about one million Iraqis were forced into internal displacement in the Kurdistan Region of Iraq (KR-I) following successful incursions of the Islamic State of Iraq and the Levant into bordering areas. To mobilize assistance and respond to the immense humanitarian needs, the UN assigned the situation its highest level of emergency, L3. This thesis investigates the emergency r

The accurate and reliable detection of opening of doors and windows is vital for home security applications. This master thesis aims to present a way to achieve this using a low-cost and low-power ecompass, containing a MEMS accelerometer and a magnetometer. This has been achieved by attaching such a device to a door and collecting sensor data when opening and closing the door. Said data were then

A growing world population and rapid urbanization have resulted in larger cities and greater acknowledgement of the importance of sustainability, hence, sustainable cities have started to emerge. In order to cope with all factors affecting sustainability, better mechanisms for decision making in those cities are requested. The purpose of this report is to increase the understanding and fill the ga

Engagemang i sociala frågor har traditionellt sett involverat ett fysiskt deltagande där människor har engagerat sig genom att demonstrera, arbeta ideellt eller donera ekonomiska medel för att försöka lösa upplevda samhällsproblem. Sedan uppkomsten av sociala medier, i synnerhet med Facebook, har möjligheter att stödja olika sociala frågor ökat avsevärt där man med hjälp av ett knapptryck kan ge sCivic engagement has traditionally involved a physical engagement in form of demonstrations, volunteering or donating money in an attempt to solve civic problems. Since the rise of social media, with Facebook in particular, the opportunities to support different causes have dramatically increased. Today, all it takes to engage in a social cause is a click of a button. The use of social media has a

The universalistic understanding of the subject embedded in the Liberal and Marxist traditions together with contrasting accounts of unconstrained agency fail to explain the contingencies of ground responses that call for social change. The paper makes a case for the opening of the understanding of the human subject when placed in the theoretical terrain of radical political philosophy elaborated

Våldtäkter som ett krigsvapen i väpnade konflikter utgör en av historiens stora tystnader. Det var först under 1990-talet, genom de internationella krigsförbrytartribunalerna i forna Jugoslavien (ICTY) och Rwanda (ICTR), som det internationella samfundet uttryckligen erkände våldtäkt som brott mot mänskligheten. Den Internationella brottmålsdomstolen, ICC, grundades den 1 juli 2002. Det var dockRape as a weapon of war in armed conflicts is one of the history’s great silences. It was not until the 1990’s, through the International Criminal Tribunals for the former Yugoslavia (ICTY) and Rwanda (ICTR), that the international community explicitly recognized rape as a crime against humanity. The International Criminal Court, ICC, was established on 1 July 2002. However, it was not until 201

Bland de mest kraftfulla händelser som människor har observerat är gammablixtar. Blixtarna är korta utbrott av gammastråalning som ibland dyker upp i rymden. Forskare har länge misstänkt att kollisioner mellan neutronstjärnor ligger bakom en kategori av blixtar, de korta gammablixtarna. För några år sedan bekräftades forskarnas misstankar. De kunde då, med det nya LIGO-observatoriet, observera graShort gamma-ray bursts are often observed at large spatial offsets from their host galaxies. Neutron star mergers in double neutron star binaries have also recently been confirmed as a progenitor of short gamma-ray bursts (Abbott et al. 2017). We attempt to constrain uncertainties in the evolution of burst-producing neutron star binaries by generating a distribution of burst offsets from the neutr

Sammanställningen av resultatet visade att Bäljane å har en relativt god status med undantag för mängden organiskt material samt att ån är starkt färgad och starkt grumlat.
