The main purpose of this study is to assess the impact of environmental conditions on paper-based flexible laminates tendency to curl. Any deviation in flatness may indeed affect materials processability. Two different paper-based flexible laminates are considered: a widely processed heat-sealable yogurt lid (paper / metallized polyethylene terephthalate / heat-sealing lacquer) and a prototype lam
Efforts to reduce energy consumption in buildings have increased with the pending impact of climate change. Heat losses through airing behaviours remain a largely unknown factor due to the variety of reasons for opening a window, making generalization difficult. Currently, an estimation of 4 kWh/m2 heated area for airing heat loss is assumed in Sweden. Additionally, the resulting airflow from open
Amelogenin, a critical protein in enamel formation, self-assembles into supramolecular structure that guide hydroxyapatite (HAP) crystal growth that is essential for the development of strong and healthy enamel. Phosphorylation of amelogenin at Ser-16 plays a pivotal role in modulating its self-assembly and functional properties, impacting the overall enamel biomineralization process. This post-tr
The details of galaxy formation are still an unsolved problem in astrophysics. Even though significant progress has been made in simulations and observations, it remains an unsolved issue to describe the complexity it yields. One of the reasons for this is the vast dynamical range in space and time. The smallest scales, where star formation occurs, are connected to the larger scale structure of th
This is the manual and user guide for the Rivet system for the validation and tuning of Monte Carlo event generators. As well as the core Rivet library, this manual describes the usage of the rivet program and the AGILe generator interface library. The depth and level of description is chosen for users of the system, starting with the basics of using validation code written by others, and then cov
Den svenska bostadsmarknaden präglas av en bostadsbristsituation, en situation som enligt Boverket förvärrats av omvärldshändelser som covid-19 och kriget i Ukraina. Det är i denna kontext intressant att undersöka orsaken och implikationerna av observerade skillnader i belåningsgrad och marknadsvärdestillväxt mellan kommunala bostadsbolag och privata fastighetsbolag. Syftet med arbetet är att unIn Sweden it has for many years been the common understanding that there is a shortage of housing on the housing market, a situation that according to Boverket has been further worsened by recent world events such as the Covid-19 pandemic and the Russian war of aggression against Ukraine. In this context it was interesting to study the cause of and implications of observed differences in the grow
This master’s thesis is written for Tetra Pak with the aim to investigate if pitting corrosion inhibition can be detected for Stainless Steel 316L in contact with dairy products in an experimental setup. The aim was also to continue developing a corrosion test method to facilitate for material selection of food pro- cessing equipment in order to reduce the extent of detrimental pitting corrosion.
The Milky Way harbors a supermassive black hole (SMBH) at its dynamical center. Surrounding the SMBH is a dense nuclear star cluster (NSC) which is believed to include a binary population. Beyond $0.1\mathrm{pc}$ from the SMBH, Eccentric-Kozoai Lidov oscillations are suppressed by general relativity precession, and the dynamical evolution of binaries are completely dominated by encounters with oth
The purpose of this thesis is to examine if Swedish sustainable funds, which invest in Swedish companies and are registered in Sweden, have a higher risk-adjusted return than Swedish traditional funds. The main purpose is to evaluate the risk-adjusted return during the pandemic Covid-19 and the ongoing Russia-Ukraine war. We construct two different portfolios; one sustainable and one traditional p
Heavy road freight transports in Sweden are responsible for a significant portion of national greenhouse gas emissions. Earlier research has looked at the purchasing process of transports in a business-to-business context and established its importance for limiting environmental impact. This thesis’ purpose is to study purchasing criteria related to the climate and explore the potential use of emi
Lake sediments have lately been explored as a 10Be archive, complementing previous research on ice cores and marine sediments. 10Be is an important proxy as it can be used to study past solar activity, a factor which affects the climate. Where other methods studying solar activity only cover a brief period of history, 10Be has the potential to go further back in time. The concentrations of 10Be st
Crowdsourcing is a relatively new technique which aims to make a specific group of people contribute solutions to simple tasks or problems that are published online by some organization. For this they get some reward, which is usually economic in nature. This technique can be embraced by any kind of company, and since it is done online, it can turn out to be a bit problematic, especially when it c
Soundcloud is the worlds third largest streaming platform for music. Despite this, the website is riddled with spam comments that disturb user experience. This spam diers much in format and content from the email spam that we are used to seeing, and that most classic spam lters have been developed to detect. On soundcloud, 90% of spam comments are written by users wanting to self-promote their own
Background: Intra- and interfractional variations in anatomy can cause unplanned substantial alterations of the dose distribution of the target in proton therapy. Motion management methods might be used in order to minimize anatomical variations. In the proton therapy of lung cancer, a potential motion management technique is the use of the voluntary breath-hold approach. The aim of this study was
The kinetics of sorption of water vapor in mature cement mortar are examined experimentally by the use of a sorption balance (DVS1000). The relative humidity in the sample chamber is obtained by mixing dry and saturated air using flow regulators with very high accuracy. A predefined change of relative humidity in the sample chamber can be obtained in about 30 s. The time needed for equilibration i
Background: The use of welfare technology is gaining ground in municipal eldercare and is increasingly being integrated into everyday routines. However, the meanings that eldercare personnel attach to welfare technology in the care of older recipients, and thus the domestication of welfare technology, remain largely underexplored. This study explores how eldercare personnel understand and ascribe
This study focuses on one of the critical design parameters of lean premixed (LPM) combustors-the air split ratio (ASR) between the pilot and main stages. The effect of the air split ratio on thermoacoustic instability is experimentally studied based on a centrally staged model combustor. It is found that the thermoacoustic instability is suppressed with the ASR higher than 20%. The acoustic modes
Realistic prediction of the near-future response of Arctic Ocean primary productivity to ongoing warming and sea ice loss requires a mechanistic understanding of the processes controlling nutrient bioavailability. To evaluate continental nutrient inputs, biological utilization, and the influence of mixing and winter processes in the Laptev Sea, the major source region of the Transpolar Drift (TPD)
