Målet med detta arbete var att studera de termodynamiska och strukturella egenskaperna hos polyetylenglykol genom att tillämpa en kombination av experiment och datorsimuleringar. Den experimentella huvudtekniken var membran osmometri och datorsimuleringarna baserades på Monte Carlo metoden. Polyetylenglykol även förkortat PEG är en neutral linjär polymer med amfifilisk karaktär, vilket menas attThe aim of this thesis was to evaluate the accuracy of a one-parameter non-virial scaling equation of state (EOS) for polyethylene glycol in water by Cohen et al. through osmotic pressure measurements using membrane osmometry and Monte Carlo simulations. PEG20 was set as the reference system and the polymer chain length effect was investigated through simulations of PEG10 and PEG35. For PEG35 expe

Att översätta en trend – En studie av institutionaliseringsprocessen av content marketing Denna studie undersöker hur ett nytt begrepp inom kommunikationsbranschen sprids och börjar etableras. De få studier inom strategisk kommunikation som beskriver spridning av nya idéer handlar nästan uteslutande om hur de har anammats av efterfrågesidan. Denna studie studerar därför hur aktörerna på produktionTranslating a trend – A study of the intstitutionalization process of content marketing. This study explores how a new term in is diffused and established. The few studies on diffusion of ideas in Strategic communication that exists have mostly been focused on the adoption. This study is therefore an exploration over how actors act on the production field of communication ideas in an institutional

Magnetit är ett mineral med ferrimagnetiska egenskaper, vilket betyder att det har två magnetiska moment riktade mot varandra. Men ett av dessa moment är dock starkare än det andra vilket gör att ett netto-magnetiskt moment bildas. Detta gör att en bit magnetit kan fungera som en vanlig handmagnet. Dessa magnetiska egenskaper hos mineralet drog tidigt till sig uppmärksamhet i gamla tider och magneThe ambition of this project is to assist in the pursuance of understanding the metal to insulator transition found in magnetite at ~120 K. The transition is itself very complex and links together the charge order, orbital order and lattice distortion of magnetite with its magnetic properties. To be able to research these relationships on a more advanced level, synchrotron methods are necessary. F

Positive aspects of fathers’ involvement in parenting are broadly recognized, but challenges faced by fathers are often neglected and postpartum depression (PPD) is still mainly considered as a problem of mothers. Yet, new evidence suggests a similar prevalence of about 10 % in fathers and mothers. The present study investigated paternal PPD, its character and its links to attachment styles, paren

A software system composed of applications running on embedded devices could be hard to monitor and debug due to the limited possibilities to extract information about the complex process interactions. Logging and monitoring the systems behavior help in getting an insight of the system status. The information gathered can be used for improving the system and helping developers to understand what c

In this report we take a new approach to product recommendation. We investigate the the possibility of using a hybrid recommender consisting of contentbased clustering and connections between clusters using collaborative filtering to make good product recommendations. The algorithm is tested on real product and purchase data from two different companies - a big online book store and a smaller onli

Höje å har de senaste 200 åren blivit 50 procent kortare och förlorat 90 procent av avrinningsområdets våtmarker. För att kunna klara av framtida behov gällande matproduktion och utbyggnad av städer krävs effektiv avvattning av landskapet. Traditionella diken är bra på att avvattna mark, men medför många nackdelar för biologisk mångfald och näringstransport från jordbruksmark till havet. Tvåstegsd

Amid the many food safety scandals and rapid urbanization, China’s peri-urban areas have recently witnessed the emergence of alternative food systems (AFSs). Situated in a context different from that of the West, their impact has remained poorly understood and under researched. This paper explores how Community Supported Agriculture (CSA) can enhance food security in China’s cities. Based on Polan

Nämndemän har varit med och påverkat dömandet i våra domstolar i mer än 800 år. Deras inflytande har varierat en del under århundradena men aldrig har de haft så stor domsmakt som idag. I tingsrätten dömer vanligtvis fyra domare varav en är juridiskt utbildad (ordföranden) och tre är nämndemän. I röstningsförfarandet väger allas röst lika tungt. Det är kommunfullmäktige som väljer vilka som ska siLay judges have been able to influence the judgments in our courts for more than 800 years. Their influence has varied somewhat over the centuries but never have they had such great judicial power as today. In District Courts there are usually four judges, one of whom is legally trained and three who are lay judges. In the voting process every judge has the same power. The city council decides who

By using panel data for 21 counties in Sweden from 2003 to 2013, the purpose of this study is to examine the relationship between tourism development and economic growth in this country, within the neoclassical growth framework. To address the objective of this study, the appropriate panel data methods are used, namely both static and dynamic panel approaches. The results show that tourism is a po

This thesis investigates and problematizes how the English-language mass media constructs the discourse on Japanese corporate governance. The purpose is to analyse and problematize the discourse on mass media with regard to orientalism. By looking at a number of examples from the discourse, this thesis questions the fundamental assumption that the mass media is an impartial conveyor of information

This thesis examines how innovation affects firm performance in the United States during the financial crisis in 2008. A difference-in-difference estimation combined with Coarsened Exact Matching is applied on a panel data set of 4,928 U.S. firms between 2004 and 2011. Two opposing theoretical frameworks concerning the outcome are used to state hypotheses regarding if innovative firms perform bett

The aim of this study was to examine the organizational conditions in foster care placements when it comes to control and oversight. More specifically its aim was to do this through a group of social workers point of view to see what their organizational experiences were to work with private companies which recruits foster care families, and whom or what they identify as the causative factors when

Välgörenhet har en lång historia i Kina och välgörenhetsorganisationer har länge spelat en betydande roll för utövandet av välgörenhet. Redan under Qin-dynastin (221-207 f.Kr) talas det om välgörenhetsorganisationer som formats av vanliga människor men främst av överklassen i samhället. Denna uppsats undersöker välgörenhetsorganisationers utveckling från dåtid till nutid. Uppsatsen berättar först

This essay aims to present and analyze the theoretical and the practical aspects of the social work education from the student’s perspectives, on how the theoretical and practical aspects have collaborated and competed during the education. It also aimed to analyze the student’s perspectives from theories of symbolic interactionism. Five students on the Social work education that studied on the

The international migration of both skilled and unskilled persons from the global South to the North has reached an alarming proportion.This study investigates the underlying factors that informed the decisions of some African students not to return to their countries of origin after graduation from the Swedish Universities. The participants are former and present students of two Swedish Universit

The shipmaster is the centralised focal point of power on a passenger ship, and upon him/her rests the decision to evacuate the ship if it is deemed to be in a situation that is non-survivable. This thesis set out to explore a societal normative view of the shipmaster in this decision space; a view that can be observed in accident reports and maritime legislation. A case study, of a government acc

Inkomsten i relation med den mentala hälsan är ett intressant och ännu inte så utforskat område inom ekonomi. Syftet med denna uppsats är att undersöka om inkomst och arbetssituation har en påverkan på den mentala hälsan samt om kvinnors och mäns mentala hälsa påverkas olika av dessa faktorer. Med hjälp av en egenskapad enkät samlades det in svar från 276 olika individer. Utifrån dessa svar utförd
