The influence of added colloidal particles on the phase stability of polymer solutions is investigated theoretically. The polymer has an affinity to the particle surface. A mean-field lattice theory based on the Flory-Huggins theory is used to calculate the phase behavior in solutions containing a single polymer component and particles. The particles are described in two different ways. The first

We used a proboscis extension reflex (PER) to study the olfactory discrimination capability in the moth Spodoptera littoralis. Already after a single experience, moths were capable to discriminate a rewarded from an unrewarded odor. In the first experiment, when rewarded and unrewarded odors were substituted for each other, moths were able to undergo reversal conditioning already after two experie

We develop an optimal control model for cost-effective management of pollution, including two state variables, pollution stock and ecosystem quality. We apply it to Baltic Sea pollution by nitrogen leachates from agriculture. We present a sophisticated, non-linear model of leaching abatement costs, and a simple model of nitrogen stocks. We find that significant abatement is achievable at reasonabl

Head-up tilt test (TT) has been used for >50 years to study heart rate/blood pressure adaptation to positional changes, to model responses to haemorrhage, to assess orthostatic hypotension, and to evaluate haemodynamic and neuroendocrine responses in congestive heart failure, autonomic dysfunction, and hypertension. During these studies, some subjects experienced syncope due to vasovagal reflex. A

This paper examines the aftermath of the 1897 Riksbank Act in Swedish banking. The Act placed banks with unlimited and limited liability upon equal footing, removing the note issuing privileges of the former. We consider whether changes in risk preferences occurred subsequent to the Act, or whether extended liability was a sufficient deterrent. We conclude that when legal differences were removed,

Den digitalisering som för närvarande äger rum inom hälso- och sjukvårdssektorn ställer både nya krav och öppnar för nya möjligheter för enskilda medborgare, vårdpersonal samt olika aktörer i samhället. I många av de e-hälsolösningar som utvecklas finns bakomliggande tankar om ökad egenmakt (empowerment) för patienten genom att denne skall få ökad kontroll över sin egen hälsa och den information sThe digitalization that currently is taking place in healthcare raises questions about how this development, with visions of more patient participation and patient empowerment, changes this sector and what role eHealth can play in these changes. The term civic health technologies (Invånartjänster) is used in Sweden to describe eHealth in the healthcare sector that is developed and deployed by the

Promoting a more sustainable development of urban realities is one of the most important goals of the recent decades. One possible strategy to undertake in order to achieve this objective is the implementation of a road pricing: tolling private cars when passing by certain roads of the network could be a way to tone down the traffic congestion and, at the same time, encourage the shifting towards

There is perennial debate in comparative politics about electoral institutions, but what characterizes this debate is the lack of consideration for citizens’ perspective. In this paper, we report the results of an original survey conducted on representative samples in 15 West European countries (N = 15,414). We implemented an original instrument to elicit respondents’ views by asking them to rate

BACKGROUND: Retrospective studies have shown promising results using artificial intelligence (AI) to improve mammography screening accuracy and reduce screen-reading workload; however, to our knowledge, a randomised trial has not yet been conducted. We aimed to assess the clinical safety of an AI-supported screen-reading protocol compared with standard screen reading by radiologists following mamm

Both in the social and natural sciences, methodologies have been developed to deal with relatively stable conditions, where findings can be validated based on past experiences. At a time when both social and natural phenomena are rapidly changing, new approaches are urgently needed to produce knowledge for systemic change, inform high-stakes decisions, and enable sustainability transitions in the

The aim of this qualitative study was to examine how four different women’s shelters talk about what happens to a woman after she has left a relationship where there has been domestic abuse. This was achieved by taking part of the different women’s shelters narratives on domestic abuse and their work through semi- structured interviews. This study focuses on how the different women’s shelters talk

The European Union has proved to be unable to efficiently deal with the refugee crisis that is devastating Middle East since 2011. The problem grew bigger in 2014 and 2015, when Syrian migrants illegally entered some frontier Member States, forcing the European Union to introduce a new relocation mechanism that is far from being more effective than previous solutions. To address this distributiona

Denna studie har undersökt högpresterande studenters upplevelser av grupparbete i syfte att utreda huruvida deras upplevelse stämmer överens med vad tidigare forskning visat gällande högpresterande elever vid grund- och gymnasieskolan, samt om de upplever att grupparbeten påverkar deras motivation. Tio semi-strukturerade intervjuer genomfördes med personer som hade blivit antagna till ett programThis study examined experiences of group-work for high-achieving students with the purpose to see if their experiences coincide with previous research concerning elementary- and high school students, and if they feel that group work influences their motivation. Ten semi-structured interviews were held with people who had been accepted into a program for high-achievers. The results indicate that th

Private equity is a growing global phenomena and private equity companies have become a major force in many of Sweden’s industries. These companies own portfolio companies which together employs around 190 000 people and have an annual revenue of over 318 billion SEK. The purpose of this thesis was to describe and analyze the Swedish private equity industry and individual companies’ competitive st

This thesis aims to bring a greater understanding of the recent rise in right-wing populism by analysing the authoritarian populist discourse used by Donald Trump when he speaks to his base. In the study, the transcript of his speech at the Minnesota Rally in October 2019 is studied with the method critical discourse psychology. The theoretical framework is a combination of post-structuralism and

A major concern of this thesis was the changing meanings of cherry blossoms in Japanese history, and the images of Japan created through the flower. With a peculiar emphasis on today’s international context, when cherry blossoms have become a unique culture of Japan, this research inquired into the process of symbol-making. The Zenith concept of nyoze and poststructural discussions on language-pow

The primary purpose of this study is to investigate if culture influences a firm’s decision to implement enterprise risk management (ERM). It will examine which factors influence this decision on a worldwide level, how ERM implementation varies across countries and to what extent these differences are influenced by cultural dimensions. The study is based on 380 firm observations from 19 countries.

Det finns i dagsläget flertalet tekniska lösningar för att begränsa konsekvenser av bränder i bostäder. Exempel på sådana kan vara sprinkler och brandvarnare. Ytterligare möjligheter för att reducera konsekvenser av brand i bostäder finns, där planlösningar i bostäder borde kunna användas som ett komplement till övrigt brandskydd. Syftet med examensarbetet är därför att undersöka planlösningar i bThe aim of this thesis is to investigate the impact of floor plan parameters in a residential dwelling regarding the consequences of fire that may endanger human life and health. The thesis follows a case study methodology and investigates isolated parameters in floor plans using CFD and CFAST modelling. The results are compared to a default case and a conclusion regarding the importance of parame
