In addition to various switch and track materials, Vossloh Nordic Switch Systems AB have a wayside lubrication device, Clicomatic© in their product range. Clicomatic© is a lubricator intended for fixed installation to mainly lubricate the railway track at exposed sections. Its purpose is to apply grease in the active interface between the vehicle and the track. Clicomatic© was developed decades ag

The purpose of our master thesis is to locate and find a mathematical model of the road surface from data obtained using LiDAR measure- ments. A LiDAR is an optical instrument that generates a point cloud of its surroundings by measuring distance and intensity. Some LiDARs also generate additional metrics, but for our road model only the distance will be used. However, we will discuss how the inte

In the field of molecular biology, the cloning of DNA is a vital process. Through cloning, researchers can design new DNA strands which can be used for a number of applications. One of these applications is the creation of synthetic antibodies for cancer treatments. Alligator Bioscience is developing a high-throughput chain to significantly speed up the process. Traditional cloning techniques rely

Dagens flyktingkris är världens största sedan andra världskriget. Idag flyr människor sina länder från förtryck, krig och förföljelser och hälften av dem är barn. Antalet ensamkommande barn har ökat under de senaste åren och under januari – oktober 2015 sökte 23 349 ensamkommande barn asyl i Sverige.1 Regeringen har lyft fram betydelsen av det civila samhället både generellt och inom integrationso

En nyfödd stjärna är omgiven av en disk som består till mestadels av gas med en liten andel grus, en så kallad protoplanetarisk disk. Det är i den här disken som planeter bildas, och likt planeter så roterar den runt solen. En viktig egenskap hos den protoplanetariska disken är att den förändras med tiden. Stjärnans gravitation drar till sig material från disken, vilken gör att den blir mindre ochThe rate of migration and accretion onto protoplanets is greatly influenced by the structure of the surrounding protoplanetary disc. This structure changes with time as the disc evolves on a million year timescale, implying that the process of planet formation might look very different depending on when it was initiated. Further on, the evolution of the disc structure is affected on smaller timesc

Drawing from 17 rounds of harmonised census data, this paper explores the link between climate variability and internal migration across six Sub-Saharan African countries. This study uses high-resolution precipitation and temperature data to construct two sets of measures capturing climate variability, the intensity of climate anomalies and the exposure to climate extremes. Two complementary hypot

Järnvägslinjen mellan Lund och Malmö upplevs som bland den mest trafikerade linjen i Sverige. För att öka dess kapacitet, mobilitet, tillgänglighet och reducera bullerstörningar finns ett stort behov av att expandera linjen. Av den anledning har Trafikverket börjat expandera de befintliga dubbelspåren som går mellan Flackarp (söder om Lund) och Arlöv (norr om Malmö) till fyra spår. För TrafikverkeThe Swedish Transport Administration (STA) has begun to expand the two lined tracks that run between Flackarp and Arlöv to four tracks. For STA, it is of high importance to manage aspects such as climate and energy issues in big infrastructure projects, especially since they must meet certain requirements. Furthermore, when performing life cycle assessments (LCA) in projects like these, the possib

Klämma, känna och lukta - En studie om vikten av närhet i en vårdgivare- och patientrelation är författad av Louise Wahren och Josefine Sjödén, vid Institutionen för kommunikation och medier vid Lunds universitet. Denna uppsats syftar till att undersöka om vårdgivare- och patientrelationen utmanas när vårdmötet äger rum i en virtuell miljö. För att ta reda på detta utgår studien från Kry som är en

Death is life ́s companion, it has existed throughout the history of humanity and of all living things. Mayan culture represents one of the oldest civilizations native to the American continent and is renowned for its traditions and spirituality. Sweden is recognized as a modern-day industrialized, technologically advanced, and secular society. How do these two different cultures handle the subjec

As the air quality in urban environments is a rising problem, a deeper understanding of how air pollution is dependent on different factors is necessary. In these environments, there are different parameters that effect how the chemical reactions of the pollutants are proceeding. Here the parameters solar radiation, temperature, humidity, emission factors and background concentrations of gaseous a

The enunciation of the principle of equality and non-discrimination is of fundamental source in international human rights laws and EU-law and has a prominent place in the Icelandic constitution. The principles of equality and non-discrimination are based on various legal concepts that have evolved mainly in international and regional human rights or equality jurisprudence. International legal pro

In order to grow, the founder must go. This is the conventional wisdom which states that when entrepreneurial firms enter a stage of rapid growth the new business quickly surpasses the skills and capacity of the founder. In this phase of rapid growth this paper aims to understand how entrepreneurs perceive their role as founder CEO as their company grows, and what impact this has on their “decisio

This thesis looks into cross-cultural in-store marketing and how, with the use of contemporary symbols, marketing messages can cross language barriers. In the context of cosmopolitan cities with large populations of international inhabitants, being able to market to all individuals regardless of linguistic abilities and cultural backgrounds is critical for firms to stay competitive. Simply replaci

3D-modeller är grunden i det som kallas BIM och är något som används mer flitigt inom byggbranschen men desto mindre inom anläggningsprojekt. BIM har utvecklats mer och mer för att underlätta samordningen av flera aktörer och lösa konflikter i olika faser och skeden. Med ytterligare dimensioner integreras även tid och kostnadsaspekten på projektet som resulterar i ett mer produktivt byggande. Gru3D-models are the base of what is called BIM. It is used more and more within in the construction industry over all, but not as much in the field of infrastructure projects. BIM is developed to coordinate several actors and resolve conflicts in different phases of the construction. With dimensions integrated in the model, such as time and cost aspect, it result in a more productive project. The m

From originally being used for software development, there is an increased use of agile methodologies in other areas as well. This leads to a need for further studies on the implementation of agile methodologies. The aim of this thesis is to study newly formed agile teams and their member’s perceptions of job satisfaction and examine if there are any relationships between the use of agile practice

Recent studies focusing on the analysis of emissions embodied in trade have shown that high-income countries are increasingly becoming net importers of emissions. This is commonly explained by the economies’ changing trade specialization in heavy and light industrial goods. The purpose of this thesis is to investigate and compare the trade specialization patterns of twelve Anglophone and Nordic co

This paper examines long-run and short-term dynamics of real house prices in Sweden from the first quarter in 1986 to the last quarter in 2017. To understand this, multivariate co-integration and error correction modelling approach are used. More specifically, this paper examines whether fundamental factors of demand and supply can explain the real house price development in Sweden. Evidence shows

The Swedish national syllabi for the subject of English challenges upper secondary students to not only produce text, but to interact with and through it; students should actively engage with the learning process through reading, writing, and speaking. Previous research within this field has investigated the relationship between reading and writing, as well as how to use writing to complement the

Eutrofiering är ett världsomspännande problem för sötvatten. Höga tillflöden av fosfor leder till försämrade förutsättningar för många typer av rovfiskar såsom abborre (Perca fluviatilis) och gädda (Esox lucius). Biomanipulation är en åtgärd som antas förbättra förutsättningarna för dessa rovfiskar, men kan samtidigt betyda försämrade förutsättningar för rovfiskarter som får konkurrensfördel av lå
