Människans fysiska behov av sömn är uppenbara, men vilken funktion fyller egentligen sömnen och drömmarna för psyket? Det är något av ett mysterium trots att både sömn och drömmar är föremål för mycket debatt, teorier och studier. I den här studien undersöks kopplingen mellan sömn, mardrömmar och försvarsstrukturer. Kan en kort sovstund dagtid påverka våra försvarsstrategier, gör den vårt psyke meThe purpose of this study was to investigate whether sleep leads to more flexible use of defense mechanisms, and linkages between defense structure, anxiety and nightmares, the two conditions, sleep and rest. 69 participants were recruited for the study and they were divided into a sleep group (n = 48) who received a period of sleep during the daytime while the other partcipants (n = 16) rested du

Abstract Responsive web design is the technique lot of companies apply to their website today. The reason is, that with this technique the website’s content adapts nicely on all devices from mobile phones to desktops. IKEA recently followed this trend on some of their platforms and among these is their internal communication platform called IKEA Inside Outside. IKEA is not entirely satisfied in

Likt andra komplexa, flercelliga organismer, består den mänskliga kroppen av en mängd olika organ ämnade för olika uppgifter. För att kunna utföra dessa uppgifter är organen uppbyggda av olika sorters celler, med speciell funktion och struktur. Trots de stora skillnaderna mellan dessa celltyper delar de samma genetiska ritning, organismens genom. Genomet är indelat i olika gener, vilka beskriverMaintenance of stem cell pluripotency and the differentiation of stem cells into specialised cells has been studied extensively. More recently, the possibility for a specialised cell to be transferred into a state of induced pluripotency has been demonstrated and investigated. Critical components of the gene regulatory networks governing these processes have been identified, but a complete model h

This narrative study aims to examine how social pedagogues perceive and relate to violence and threats of violence in a social educational context in Denmark. Furthermore, the study examines how these perceptions affect the relational aspect of the profession. My interest in the subject is sprung out of personal experiences in multiple socio-educational projects. As such, my material is composed b

The aim of this thesis is to explore the relative importance of the eight psychological Active Innovation Resistance (AIR) barriers, from the new typology of AIR barriers developed from Talke and Heidenreich in 2014, on the consumer’s intention to adopt or buy circular fashion products. Moreover, this thesis examines whether the socio-demographic factors of age, employment status, and educational

Shared Reading is a reading promotion concept that originated in the United Kingdom and has, over the past three years, begun to engage various actors in Sweden including the Swedish hospital library. In the use of the method, health-promoting effects have also been identified, which is why Shared Reading has interested research in so-called medical humanities in a Swedish as well as an internatio

This thesis investigates the effect of visible articulatory movements on speech comprehension in L1 and L2 listeners of Swedish. Previous research found faciliatory effects on speech perception when speech was presented audiovisually in various settings and under diverse listening conditions for both L1 and L2 listeners. However, it is still not investigated thoroughly, how L2 proficiency affects

Denna studie utgår från två miljökampanjer som skapats med grund i Cacioppo & Pettys (1984) “Elaboration likelihood model”, som kortfattat menar på att vi kan processa ett meddelande på antingen ett s.k perifert- eller centralt plan. Utifrån detta har vi skapat två kampanjbilder med fokus på miljöproblem, där den ena innehåller perifera- och den andra centrala budskap. Dessa användes för att uThis study stems from two environmental campaigns which have been created with Cacioppo & Pettys (1984) “Elaboration likelihood model” as a foundation, which in summary says that we can process a message through a peripheral- or central mindset. Using this as a starting point, we created two campaigns that focus on environmental issues, one contains peripheral- and the other central cues. In o

Vindkraftverk är ett av samhällets främsta verktyg för en miljövänlig energiproduktion. Den konventionella designen av bladen är emellertid i stort sett oförändrad. Triblade är ny typ av design som har potentialen att revolutionera marknaden. Genom att använda en fackverksstruktur öppnar man för möjligheten att utforska andra materialval än de konventionella kol- och glasfibermaterial som anväIn the 21st century, wind power has emerged as a strong candidate in fulfilling societies goals of achieving carbon-free energy energy production. Windpower has evolved along with other technological developments, giving rise to larger turbines, but with the overall design trend remaining largely unchanged. Winfoor, a Swedish company based in Lund,aims to break that trend. With their new Triblade

The vehicle industry is making great strides in electric and hybrid technologies, representing a significant step towards reducing emissions from personal vehicles. In order to make the transition to new hybrid technologies as convincing as possible, well-functioning and smooth transitions between traditional combustion engines and electric motors are required. So-called mild hybrids enable a cos

Migration to wintering grounds is a process that a large proportion of songbirds perform every year. It has been suggested that there are differences in the migration performance between adults and juveniles due to the experience the former have over the latter, after having flown this journey before. The aim of this study was to analyse age differences regarding activity, energy deposits and depa

Ökad noggrannhet vid ATLAS experimentet Var kommer vi ifrån? Vad hände i Big Bang? Detta är exempel på några av många obesvarade frågor inom fysik. ATLAS är ett experiment vid CERN (Europeiska organisationen för kärnforskning), där tusentals forskare samarbetar med att undersöka produkterna från högenergetiska protonkollisioner, för att få svar på dessa frågor. En vanligt förekommande produkt The Standard Model of particle physics (SM) attempts to describe the fundamental particles and how they interact with each other. This model is however incomplete, as shown by various experimental observations. ATLAS is one of the experiments currently in operation at the Large Hadron Collider, which aims to search for new physics beyond the SM. To perform these searches, many ATLAS analyses look

This thesis sets the goal to contribute to the field of diaspora studies from media and communication studies perspective by focusing on the neglected migrant group of highly educated refugees and their media use. This thesis aims to explore how highly educated refugees utilize digital media in their everyday life after their migration. It also investigates how digital media use enhances and under

Thesis purpose: In order to contribute to Consumer Culture Theory, as well as critical dimensions in the foodie literature namely authenticity, democracy/distinction and gender, the study’s aim is to explore how discourses and socio-cultural meanings underlie identity constructions in the specific sourdough culture. Theoretical framework: As no research addresses the sourdough phenomenon directly

The construction sector is often criticized for its lack of efficiency and quality.When the construction industry is compared to the rest of the domestic manufacturing industry, the general conclusions of the industry’s low efficiency is confirmed. The purpose has been to clarify why there is no sustainable building, despite the well-developed technology that now is available. The report also exam

Abstract: Background: Breast cancer is the most common kind of cancer among women in Sweden. While the short- to mid-term survival chances are good, the long-term survival chances are poor, and a large number of women are also likely being overtreated and thus suffer from unnecessary side effects. The South Sweden Cancerome Analysis Network - Breast (SCAN-B) Initiative aims at improving breast ca

Background The fierce competition in the telecom industry makes operators heavily invest in acquiring new customers. This is most often done with marketing campaigns and subsidies of handsets. But to be truly profitable, it is crucial not only to attract new customers, but also to make sure they retain with the company for as long time as possible. This turns the mobile operators’ attention to cus

Är en sur vattenmiljö dålig för bakterier? Bakterier finns överallt på vår planet och är bland annat viktiga för nerbrytningsprocesser i naturen. De bakterier som klassificeras som heterotrofa livnär sig genom att bryta ner döda växt-och djurdelar och omvandla detta till energi. I sjöar och vattendrag utgör dessa bakterier en central del, då de kan utnyttja resurser som är otillgängliga för andraAbstract The environmental pH is an important factor affecting bacterial physiology and function as well as community composition in soil and marine ecosystems. However, studies of the effect of pH on bacterial function in limnic systems have been scarce. Considering studies in soil where it has been conclusively confirmed that bacterial growth rates (μ) are considerably lower in a low pH environ
