During the spring semester 2018, an investigation about supplementary cleaning of the waste water at Dow Chemical site in Landskrona was done. Different water-based binders from acrylic monomers are produced by Dow and large amounts of water is used for such processes. The wastewater, that is treated currently by ultrafiltration (UF), contains different chemical residues such as surfactants, resid

The B-format is an audio format capable of reproducing full spherical surround audio, meaning sounds can appear as if coming from any direction around the listener. This thesis investigates an approach to quantify and manipulate the spatial information carried in B-format audio signals. It describes an analysis method and a corresponding model for quantifying the spatial data. Two types of appli

Previous research shows that gender is a strong predictor of household labour division in heterosexual households. Same-sex couples cannot use gender and social norms associated with them as a starting point for initial household labour allocation. Although literature on household labour division is extensive, it does not elaborate enough on same-sex households. The aim of this study is to fill th

For this exploratory study, I reached out to all 302 individuals that were listed as PhD students at the psychology departments of all Swedish and Dutch “Top 100” universities. The final 111 participants (37.9% response rate) were asked to indicate how often they encountered questionable research practices (QRPs) and replied to items asking about the impact of QRPs on themselves and their environm

In media today, sex offenders are often described as horrible, monstrous people and are frequently faced with hatred, sometimes in the form of threats of violence. Threats like these can result in sex offenders getting granted identity confidentiality, which has led to a public outrage. Is it fair that high risk sex offenders, who destroyed the life of innocent victims, are getting help from the a

One third of food produced for human consumption ends up as food waste. Globally this amounts to about 1.3 billion ton per year. Food waste are large amounts of food that are thrown away, but could have been eaten if treated in a different way. Food waste means waste of resources such as land, water, and energy. In high-income countries like Sweden the largest food waste occurs at consumption stag

Emotioner har studerats och varit viktiga för att förklara och förstå sociala händelser hos många av sociologins klassiker. Emotioner påverkar kvaliteten på relationen mellan människor och känslor kan både skapa avstånd som närhet till andra . Det finns en mängd olika emotioner som upplevs både positiva eller negativa. De väcks i relationen till andra människor, i olika situationer och på olika ar

Warehouse operations are considered a key aspect to the success of a supply chain. They are not only costly to the supply chain but they also affect the flow of material both upstream and downstream. Warehouse improvement measures play therefore a considerable role in decreasing cost and lead time by improving material flows. To increase the efficiency of material flows and aiming to reduce labor

A statistic released this year (2018) by the World Road Transport Organization shows that more than 80% of inland freight is moved by road. Frequent e-commerce activities and end-consumer demands on delivery performance have increased transport needs yet fill rates have decreased. Transport is less efficient and unsustainable while profit margins also shrink, motivating fiercer competition among s

The purpose of this study was to investigate the supervision of non-smoking school yards in Sweden. Smoking costs Swedish society an estimated 30 billion SEK annually in cost for healthcare, production losses and sick leave. Smoking among adolescents has declined in recent years, but it is still 24 % in high school's grade 2, which categorized as smokers. The supervision of the schoolyard is t

This study is based mainly on assessing damage done to asphalt by trucks within the load bearing class 4 (BK4). BK4 is a new vehicle rating class for heavy duty vehicles, which refers to an increase of the maximum permissible gross weight to 74 tonnes (for the current 64 tonnes, BK1) for trucks, and which the government has completed implementing the summer of 2018. Since there is still doubt as t

Internationally there has been a growing interest of tramways the past decades. Swedish cities have taken notice of the positive characteristics that tramway have on cities and many of them has also begun investigations for future projects including tramway. The purpose of this study was to investigate in which ways tramways can contribute in creating attractive cities. The work consists mainly of

Currently, there is a lack of qualified workers of all categories in the construction industry in Sweden and it is difficult to recruit people with the right skills. Therefore, it's important that the construction industry works to increase its diversity and change the way people communicate with each other at the construction sites. This study is designed to investigate what the challenges of

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 prevalence of ageing population and growing old-age consumption per capita has raised concern about the fiscal burden of state and family. As individuals age, they have increasing need for assistance in activities of daily living (ADL). Therefore, long-term care makes up the most in the consumption of elderly. State and family are responsible to meet this demand and the care distribution depen

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

Heart rate variability (HRV) is a term within cardiology describing the natu- rally occurring variation of the time interval between heartbeats, and high HRV activity has been linked to both cardiovascular and non-cardiovascular health. This bachelor thesis aims to find differences between HRV-signals where short term physical strain (pain) was induced and HRV-signals where no such strain was appl

The purpose of this study is to investigate the influence of family composition and work-related characteristics on retirement and to identify to what extent these factors explain the differences in retirement rates between men and women. This study is conducted under a life-course perspective framework and uses a logistic regression and a Blinder-Oaxaca decomposition analysis as methodological ap
