A low creep rate and a long lifetime are important mechanical properties for corrugated board and its constituent’s linerboard and fluting. These properties ensure that the package protects the goods during the entire duration of transport and storage. This study involves several creep and tensile tests of linerboard in the machine direction (MD). The objective is to investigate how free or rest
Sweden has long cultivated an international identity as a “moral authority” by promoting democracy, international law and human rights. However, its foreign policy toward authoritarian regimes has shown inconsistencies with these core values. This thesis investigates this discrepancy through a comparative case study of Sweden’s bilateral relations with Iran and Saudi Arabia. These two countrie
Peripartum hysterectomy (PH), the surgical removal of the uterus during the peripartum period, is a rare but potentially life-saving intervention for severe obstetric complications such as major haemorrhage, uterine rupture, and placenta accreta spectrum (PAS). As a maternal near-miss event, PH carries substantial maternal and neonatal morbidity, mortality, and long-term psychological impact. Data
With the aim to develop vanadium redox flow battery (VRFB) membranes beyond state of the art, we have in the present work functionalized poly(p-terphenylene)s with highly acidic perfluorosulfonic groups and investigated their performance as proton exchange membranes (PEMs). Consequently, two poly(p-terphenylene alkylene)s tethered with perfluoroalkylsulfonic acid and perfluorophenylsulfonic acid,
Swedish healthcare, run by local governments at both the regional (county) and the municipal levels, has been under pressure during the last 15 years, following increased scrutiny of performance and demand for cost-containment. Health-care expenditures per capita and levels of resource inputs have grown, but more slowly than in other EU countries. At the same time, the number of elderly people has
Nanowire (NW) arrays containing a top segment of GaxIn1–xP are investigated, comparing NWs grown using two different Ga precursors, trimethylgallium (TMGa) and triethylgallium (TEGa). TMGa is the precursor commonly used for the particle-assisted vapor–liquid–solid (VLS) growth of GaxIn1–xP NWs. However, it shows inefficient pyrolysis at typical NW growth conditions. The use of the alternative prec
We study how a neutralising cloud of counterions screens the electric field of a uniformly charged planar membrane (plate), when the counterions are characterised by a distribution of charges (or valence), n(q). We work out analytically the one-plate and two-plate cases, at the level of non-linear PoissonBoltzmann theory. The (essentially asymptotic) predictions are successfully compared to numeri
The purpose of this essay is to investigate how employers’ rights to give employees notice because of illness are regulated in Swedish working life. This essay consists of two parts. The first part is jurisprudential and based on traditional juristic method. The second part entails the discipline Sociology of Law and is based on a qualitative survey consisting of two interviews. The outcome of thi
Migration and Asylum-seeking has been a phenomenon for a long time in the world history. Due to many conflicts in the world events of 2015, it has been a risen migration to Sweden. The Swedish government meant that the situation with the high amount of arriving-migrants was unbearable and a direct threat to the safety in Swedish society. This because other EU country governments did not follow the
This thesis explores some of the possibilities of demand side optimization in online advertising, specifically how to evaluate and bid optimally in real time bidding. Theory for many types of optimizations is discussed. The thesis evaluates auctions from a game theory and control theory perspective. It also discusses how big data sets can be used in real time, and how agents can explore unknown st
Popular Abstract in Swedish Summary in swedish Perinatal dödlighet bland invandrare från Afrikas Horn. Vikten av erfarenhet, rationellt tänkande och traditioner vid riskbedömning av gravida invandrarkvinnor. Avhandlingen visar att barn till kvinnor i invandrargrupper från Afrika söder om Sahara (majoriteten från Somalia och Etiopien), har högre perinatal dödlighet jämfört med barn till svenska kThis thesis is an exploration of the possible effects of maternal country of origin on the risk of perinatal mortality (PNM). Increased risk of PNM was found among infants of foreign-born women delivering in a Swedish hospital between 1990-1995. After adjustment for risk factors, however, the finding only held true for a subgroup of women from Ethiopia and Somalia (ES). In searching for the mecha
Three young adults with cerebral palsy who used Voice Output Communication Aids (VOCAs) with Blissymbolics took part in a study where they tried pre-stored phrases for specific activities. Before and after the study, 1 ½ years apart, they took part in semi-structured interviews where they answered open ended questions about the activity shopping. Analyses of the expressions they constructed with t
The climate is changing, something that many scientists correlate to increased emissions of greenhouse gases. The effluent that is considered to have the highest impact on global warming is carbon dioxide, when effect and quantity are taken into account. Most projections however, show that the effect is reversible if the amount of carbon dioxide emissions discharged to the atmosphere is decreased.
Background: It has long been argued that decision support systems are used to simplify and support businesses. The creators of the Balanced Scorecard, Kaplan and Norton, have developed their own software application to facilitate and create a support to organizational strategy work. The application is called the Executive Strategy Manager (ESM) and is an online application aimed at helping organiz
The study aims at exploring the links between peacekeeping operations and economic growth. The paper examines the countries in which past United Nations Peacekeeping Operations have been present and calculates the growth rates before, after and during each operation. Comparisons of the growth rates are made to show how the operation has affected the economic growth in the country. It is also discu
The connection between water and conflicts has a long-standing history in southeast Lebanon. It has created a perception of threat to the water security, which affect the development of the area. The aim of the research was to contribute to the under-researched discussion about how perceptions of water security are affected by conflicts. The research questions were concerned with how the Israeli
Populärvetenskaplig sammanfattning: Supernovor och andra galaktiska system skickar ut mängder av atomkärnor med nära ljusets hastighet, så kallad kosmisk strålning. Eftersom supernovor framförallt finns i spiralarmarna i vår galax och jorden över långa tidsperioder rör sig relativt spiralarmarna så har det föreslagits att kosmisk strålning inte varit konstant under jordens historia. Vidare har visIt has been suggested that the cosmic ray flux varies as Earth moves relative to the spiral arms in the galaxy. However, no satisfying record over the cosmic ray flux over long time scales has been presented. This work aims to investigate the possibility to use cosmic ray tracks in silicate mineral inclusions in sediment-dispersed extraterrestrial chromite (SEC) grains as such a record. Chromite i
Algae blooms, induced by eutrophication, have been an increasingly prevalent environmental concern in the Baltic Sea since the 1970s, causing ecosystem degradation and hypoxia in bottom layers. One predominant harmful algae bloom-forming species in the Baltic Sea is the cyanobacteria Nodularia spumigena. N. spumigena produces hepatotoxin nodularin and is a diazotrophic alga; hence, it should be
