Establishment and Optimisation of Small and Large Intestinal Organoid Cultures for in vitro Studies on Murine Rotavirus

Despite available vaccines, rotavirus (RV) gastroenteritis remains to be an alarming cause of under-five mortality, especially in developing countries. Research on RV has been limited by the lack of faithful in vitro models that mimic virus-host interaction and RV pathogenesis in the intestine. Most recently, adult stem cell-derived organoids have advanced the understanding of the cellular mechani

Conversational Games of Advertising: A discussion from the perspective of Grice's maxims

This essay explores the employment of Grice’s maxims and conversational implicature in commercial advertising. Advertisers tend to flout Grice’s maxims to make a greater impact on customers. The interesting thing is that, as my analysis has shown, certain flouted maxims tend to co-occur. Moreover, flouting of the conversational maxims does not necessarily augment the impact. In fact, undue floutin

Refinement of Fate Specification in Induced Erythroid Progenitors

Production of Red Blood Cells from Skin Cells Red Blood Cells (RBCs) are most important when it comes to delivering oxygen to different tissues and organs. This is why their production has to be continuously maintained. It is estimated that in humans over two million RBCs are produced every second to replenish the pool. On average their life span is around 120 days before they die and get replace

Investigation of α-thioaryl galactopyranosides to improve affinity towards Galectin-9N

Galektiner är en proteinfamilj som har visats vara aktiv i cancerceller. Proteinet har bland annat funktioner så som utveckling och spridning av cancerceller. För att förhindra proteinets inblandning i cancercellen kan man introducera en inhibitor, som hindrar aktiviteten hos proteinet. Genom att inhibitorn placerar sig i den position där substratet naturligt skulle binda. Inhibitorn tävlar med deGalectins are a family of carbohydrate recognition proteins involved in modulation of cell signaling and cell adhesion. galectin-9 especially is involved in regulation of the immune response. In this work, galectin-9N inhibitors have been designed, synthesized and evaluated. The aim was to synthesize compounds with higher affinity than currently known compounds. Three compounds were synthesized wi

Intergenerational transmission of homophobia

Previous studies are divided in the question if there exist an intergen- erational transmission of homophobia, whereas some have found a weak or no relationship, while others found a positive relationship. This paper uses the epidemiological approach by Fernandez (2010). The method regress sec- ond generation immigrant on ancestral country values. The main idea of the method is to identify the eff

Asymmetric effects of monetary policy

This thesis analyses if macroeconomic policy has asymmetric effects on output and unemployment, comparing the effectiveness of monetary policy when the output gap is positive to when it is negative. Asymmetric effects may be present due to uncertainty and loss aversion, the downward-stickiness of prices, or financial market imperfections. The empirical analysis is conducted through a panel data re

BIM to GIS-based building model conversion in support of urban energy simulation

In the context of growing population and increasing greenhouse gas emissions, urban energy planning is becoming a topic of high concern. With the rapid pace of urban construction, it is claimed that 40% of America’s total energy consumption is accounted by the building sector. Energy modelling and simulation are believed to be effective in supporting urban energy planning. Today, the growing avail

LABORATORY TESTING RELATED TO UNLOADING MODULUS OF SOFT CLAY

När jord avlastas kan denna svälla, något som kan ge tryck och således skador på konstruktionsdelar som har kontakt med den svällande jorden. Det är därför av stor vikt att ha kunskap om hur jorden beter sig vid avlastning och detta undersöks vanligtvis i geotekniska laboratorier. I detta examensarbete studerades svällningen av lera, erhållen från Göteborgområdet, som avlastas med hjälp av en modiThe unloading modulus, together with the permeability, are responsible for the swelling process of a soil that is subjected to unloading. Studies to examine the unloading modulus of clay has previously been performed and several relationships describing this parameter has hence been developed. The methods to study the unloading modulus has previously been both laboratory studies and field measurem

A Reduction in Sick leave Pay Keeps the Doctor Away?

Compensation for sickness absence reached a peak in Sweden by the late 1980s. A generous sickness benefit system was met by high levels of absence. By the early 1990s, the Swedish economy was in deep crisis. In response, the Swedish government restricted sickness benefits and privatized short-term sick leave payouts. This thesis asks whether sick leave reforms reduced Swedish sickness absence and

Från individ till ingenjör: en fallstudie om ingenjörsstudenters socialisation in i yrket och dess genusordning

This essay will explore the socialization process of students to a working profession. We have discovered a gap in previous studies when it comes to the effect of gender and class of the process of socialization and the creation of the students working identities. The study if carried out by interviewing students that have completed at least half of their bachelor’s degree in engineering, with the

On Robustness of Equilibria in Transportation Networks

As infrastructural systems become ever more complex and interconnected, they may also become ever more vulnerable to system-wide faults due to local disturbances. As such it is of great importance to design these system to be resilient, i.e. to be able to withstand and recover from disturbances or new conditions. In the case of traffic networks, while much work has been done to analyze the stabili
