We showed that breast cancer cells are affected by fat cells regarding both cell growth and movement. B

Re-placement of selves – An anthropological study of place-based engagement in a Danish community health center

Abstract: This thesis is an anthropological study on how a group of people suffering from Posttraumatic Stress Disorder [PTSD] construct meaning in a community center in Copenhagen. The specific aim of this thesis is to investigate how place can be understood as a factor that plays into well-being and recovery. Based on a case study of a Danish community health center, this study shows how users

The Role of Human Plasminogen in the Virulence of Helicobacter pylori

Helicobacter pylori is an important pathogen inhabiting the human stomach. H. pylori binds plasminogen, a 90 kDa glycoprotein secreted by liver cells, and utilizes it for enhancing virulence. Surface receptors on the bacteria recognize plasminogen that is then activated into plasmin by host factors. The active plasmin can degrade a range of host proteins including proteins of the extracellular mat

Att skapa en produkt av vanlig natur. Exempel Örkelljunga

Globalization has led to an increase in competition between places in hopes of attracting mobile capital and investments as well as new inhabitants and tourists. Nature-based tourism has become one of the most steadily growing markets for tourism in Europe. In order for a place to be attractive it has to have a brand that can be constructed depending what sort of resources a place has. A place is

Viro - ett framtidskoncept kring hanteringen av virussmitta på arbetsplatser

My master degree project started with an open brief, setting out to explore new possibilities within healthcare in relation to the benefits of IoT. By looking at medical trends, cutting edge diagnostic technologies, hypothesis about the future and by interviewing patients and medical personnel a couple of interesting project directions emerged. A decision was made to focus on prevention and one to

Prevalence, phylogenetic relationship and host specificity of haemosporidian blood parasites in a northern bird community

Avian malaria parasites can have severe fitness effects on the host although most infections seem to be mild. Some of the avian malaria parasites are host specific and infect specific bird species while others infect a wide range of species. Avian malaria can serve as a natural model system for studies of the effect of environmental change on parasites distribution patterns. The global changes of

Bumblebee biodiversity in urban habitats of Malmö: examining the importance of urban green space quality for conservation of pollinators

Bumblebees and other pollinators are important contributors to the ecosystem service of pollination of wild plants and crops. As in many pollinating insects, their abundance and diversity have declined in recent years, due to loss of natural habitats and fragmentation associated with urbanization and agricultural intensification. However, in urban areas, green space management beneficial to pollin

Assessing Body Appreciation and Body Satisfaction with Statistical Semantics: The Benefit of Using Words Instead of Numbers

Body appreciation-unappreciation and body satisfaction-dissatisfaction are in the literature seen as conceptually different, but construct distinction has only been supported using qualitative methods. Because of limits in using Likert-style questionnaires to measure multidimensional constructs, quantitative research has yet to directly demonstrate that it is possible to appreciate the body withou

Herrens hus och himmelens port : En studie om kyrkobyggnaden som ecklesiologisk symbol i några svenska kyrkoinvigningspredikningar

The purpose of this essay is to investigate the ecclesiological meaning of church buildings in the context of the Church of Sweden. In order to investigate views of ecclesiology and church self-understanding through history, based on the church building as a symbol, I have chosen to study how church buildings are presented in several Swedish sermons. In this essay I analyze and compare four sermo

Engineering of central carbon metabolism in recombinant Saccharomyces cerevisiae for improved production of biopolymers

En viktig komponent i vårt moderna samhälle är plaster och användandet av detta material ökar. Plaster skapas av komponenter som extraheras från petroleum, ett icke-förnybart fossilt bränsle. För en hållbar framtid måste användandet av petroleum minska. Alternativ till petroleum-baserade plaster är bio-plaster. Bioraffinaderier använder idag mindre än 20 % av biomassan för etanolproduktion, överskBioplastics are a promising alternative for petroleum-based plastics that today is on high demand in our contemporary lifestyles. They are made from biopolymers such as polyhydroxyalkanoates (PHAs). Producing biopolymers from waste material feedstock using microbes increases profitability and environmental benefits as well as sustainability for biorefineries. Saccharomyces cerevisiae is a robust m

How Do Bumblebees And Honeybees Exploit Food Resources In Different Habitat Qualities?

Foragers increase their fitness by choosing the most profitable food source to forage on. Food resource is spatially distributed in a landscape context and, most importantly, in a patch scale. Therefore, they have to make daily decisions about where to forage based on their ecological information about the surrounding environment. There is a lack of descriptive studies on the relationship between

Soil drying-rewetting and its influence on ecosystem carbon fluxess

Torr jord ger ifrån sig mer koldioxid när det regnar När det regnar på torr jord bildas under en kort tid mycket mer koldioxid än vad jorden vanligtvis avger. Detta fenomen har varit känt sen 1950-talet och kallas enkelt för torkning och återfuktning. Även om vi vet att det sker så vet vi väldigt lite om varför det sker. Till en början trodde man att det hade att göra med en ökad aktivitet hos ma
