Dividing wall columns are single shell distillation columns which are thermally fully coupled. DWC has the ability to create three product streams from one feed stream. A simulation of DWCs is hard due to the complexity of the system. Unfortunately, there is no good software package that can be used for simulations. Instead a detailed flowsheet with the right components and good arrangement over t
In adaptive deep brain stimulation, a treatment for motor symptoms in Parkinson’s disease, the target of the stimulus is usually in the sub-thalamic nucleus or the globus pallidus. In this thesis, a new stimulus target called reticular thalamus is investigated in a rat model of Parkinson’s disease. The responses to the stimulus were recorded from both local field potentials and action potentials f
The aim of this studie was to examine how self-identified pedophiles describes pedophilia, and it´s linkage to child sexual abuse, on their blogs. There are currenty limited research on self-identified pedophiles, which means that pedophiles outside clinical- and criminal settings are not being represented in the avalible research. Theese individuals are valuable for the research of pedophilia, be
Have you ever taken a closer look at the packages in your home? They consist of several layers of different materials, among them layers of polymer. They all contribute to protect the product.In this thesis methods for measuring and calculating the adhesion between the inside polymer layer and the aluminium layer of Tetra Pak’s packaging materials have been investigated. This was done both by exploring the possibilities of combining peel tests with the ICPeel method, and by developing ideas for new measuring methods. One of the ideas was built on a test setup for a close-to normal dire

The symptoms caused by long screen time are referred to as Computer Vision Syndrome (CVS), and the two most common o
Vattenkanaler kallade akvaporiner finns i kroppen för att transportera vatten och därmed reguleras vattennivån i cellerna i kroppen. Denna process kallas trafficking vilket förenklat betyder att akvaporinen förflyttas och blir aktiverad eller avaktiverad för att öka eller minska flödet av vatten. Om denna process inte fungerar på ett korrekt sätt, kan diverse sjukdomar uppstå som orsakar problem för peWater is a large part of life on earth and is also a large part of the human body which is why it is so important. Aquaporins are water channels that transports water through a process called trafficking. Aquaporin 2 is one of these aquaporins and with a faulty trafficking or mutations it could lead to nephrogenic diabetes insipidus and severe dehydration. Ezrin is a protein in the body which FERM
To control an accelerating proton beam that travels close to the speed of light, a large number of beam diagnostic instruments are needed. One of the instruments that will be used at the accelerator of the European Spallation Source is a Non-invasive Profile Monitor (NPM). Once installed, this system will measure the transverse beam profile by imaging the fluorescent gas induced by the accelerated
Amelogenin is a major constituent of enamel matrix protein that is responsible for the development of tooth enamel. Due to its self-assembly and physicochemical properties, amelogenin has been widely used as one of the natural biomaterials. Amelogenin, along with the other enamel matrix proteins have been known for its regenerative properties. The purpose of this project is to evaluate the enginee
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
Denna studie ämnar öka förståelsen om hur lobbyarbete bedrivs i Sverige, hur det förstås och porträtteras av lobbyister själva samt vad det får för konsekvenser för demokratiska värderingar. Studien utgår från lobbyistens perspektiv och kompletteras med den allmänna bilden av lobbyism från media och riksdag. Analysmetoden för studien är hermeneutisk där kvalitativa intervjuer samt innehållsanalys This study intends to increase the understanding of the ways that lobbying is executed in Sweden, how it is understood and portrayed by lobbyists themselves and what the consequences for democratic values are. The study was conducted from the perspective of lobbyists supplemented by the general perception of media and government. The analysis was conducted trough hermeneutics where data from quali
Populärvetenskaplig sammanfattning Morgondagens energi Vind-, och vattenkraft tillsammans med solenergi är de enda energikällorna vi har som inte leder till avfall som ökar växthuseffekt eller avfall som vi inte kan göra oss av (från t ex kärnkraftverk). Men solpanelerna som finns idag för kommersiellt privat bruk ligger på en effektivitet kring 15%. Att utveckla nya molekyler som kan omvanlda solThe aim of the study was to theoretically investigate if a proton coupled electron transfer (PCET) was feasible for a molecular system consisting of a light harvesting complex, ruthenium(tris-2,`2-bipy)2+, with different organic moieties serving as PCET (proton coupled electron transfer) relays. These light harvesting complexes are also sometimes referred to as dyes. By studying the energy levels

Tillgången till rent dricksvatten varierar mellan olika delar i världen. Till exempel är grundvat- ten en stor resurs i Sverige där det står för 50 % av dricksvattnet, både artificiellt och naturligt bildat. Den siffran är endast 6 % i Moçambique och med tanke på att 47 % av populationen i landet saknar rent dricksvatten kan artifici- ell grundvattenbildning vara ett bra alternativ. Det finns olikThe amount of clean drinking water varies across different parts of the world. For example is groundwa- ter a big resource in Sweden and stands for 50% of the drinking water, both artificially and naturally recharged. The corresponding fraction is only about 6% in Mozambique and considering that 47% of the population in Mozam- bique lacks clean drinking water artificial recharge might be a good op
The tradeoff between risk and return is a topic that most investors consider carefully before an investment decision is made. Markowitz’s pioneer work on portfolio selection using the mean-variance framework has entailed a great extent of research in this field. One research is the Sharpe ratio, which is a measure of a financial performance using variance as a risk measure. The shortcoming of vari
Den underkambriska lagerföljden i Skandinavien domineras av ljusa, marint avsatta sandstenar och når i Skåne en mäktighet av 120 m. Dess omfattande blottningsgrad har gjort den intressant för olika geologiska undersökningar. På Österlen i sydöstra Skåne är underkambrium blottad vid kusten och i nedlagda stenbrott utanför Simrishamn. Försöken att stratigrafiskt dela in den underkambriska lagerföljThe Lower Cambrian sedimentary succession in Scandinavia is dominated by shallow marine sandstones. In Scania, southern Sweden, this succession is about 120 m thick. Outcrops mainly comprise shore cliffs and abandoned quarries, primarily near the Simrishamn area. Several authors have subdivided this succession stratigraphically by different standards, which has led to confusion and the need for a

Att verkställa och genomföra politiska protester sker inte bara utomhus. Ett antal politiska protester har hållits i tv-spel, där spelare använder funktioner i spelet för att förmedla politiska budskap. I en värld där det finns stora möjligheter att kommunicera online, finns också möjligheter för spelare diskutera dessa protester i onlineforum. 2020 hölls två politiska protester i Nintendo-speletExecuting and performing political protests is not just for the streets. A number of political protests have been held in video games, using the features of the game to convey political messages. In a world where there is ample possibility to communicate online, players are able to discuss these protests in online communities. In 2020, two political protests were held in the Nintendo game Animal
With the increased loss of control over the organizational identity (OrI) in social media, research has started to encourage organizations to hand over control of the OrI to the creation and distribution of stakeholders. This has created challenges for the strategic communicator in managing the OrI internally, as the employees adapt to the OrI in the mind of the stakeholder rather than the OrI set
