Purpose: The aim of this study is to unravel consumer motives for enrolling in multiple programs and explore the consumer experience of multiple memberships in the highly competitive loyalty program market. Methodology: We have conducted a qualitative research with a hermeneutic approach. A sample group of nine women in the ages 47-62 were selected based on a snowball sample. Through detailed acco
The gene, acyl-CoA:diacylglycerol acyltransferase1 (DGAT1), was recently identified as the one underlying the quantitative trait locus (QTL) for milk production traits in the centromeric region of the bovine chromosome 14. Until now, 2 alleles, the lysine variant (increasing fat yield, fat and protein percentage) and the alanine variant (increasing protein and milk yield), were postulated at DGAT1
The molecular weight distribution and the viscosity of water‐soluble dietary fibre polysaccharides isolated from green beans, Brussels sprouts and green peas were investigated following boiling, microwave treatment and canning. Blanching was used as a reference process. In green beans and Brussels sprouts microwave treatment had minor effects, while there generally was a small decrease of neutral
One strategy to achieve coordination of care for older people with complex care needs is the establishment of shared care plans. The aim of this study was to explore the process of establishing a shared care plan from the perspective of elderly people and their next of kin. Data were collected via 12 semi-structured interviews with 12 older persons targeted in joint care planning and 11 next of ki
In the present study, we correlated the various lifestyle habits and their associated mutations in cell cycle (P21 and MDM2) and DNA damage repair (MLH1) genes to investigate their role in gastric cancer (GC). Multifactor dimensionality reduction (MDR) analysis revealed the two-factor model of oral snuff and smoked meat as the significant model for GC risk. The interaction analysis between identif
Isolation of DNA from blood and buccal swabs in adequate quantities is an integral part of forensic research and analysis. The present study was performed to determine the quality and the quantity of DNA extracted from four commonly available samples and to estimate the time duration of the ensuing PCR amplification. Here, we demonstrate that hair and urine samples can also become an alternate sou
Malignant melanoma is one of the most aggressive skin cancers with high potential of visceral dissemination. Since the information about melanoma genomics is mainly based on primary tumors and lymphatic or skin metastases, an autopsy-based visceral metastasis biobank was established. We used copy number variation arrays (N = 38 samples) to reveal organ specific alterations. Results were partly com
Aim: Extrauterine growth restriction is common among extremely preterm infants. We explored whether intake of unpasteurised maternal milk (MM) and pasteurised donor milk (DM) was associated with longitudinal growth outcomes and neonatal morbidities in extremely preterm infants. Methods: Observational study of 90 preterm infants born between 2013 and 2015 in Gothenburg, Sweden. Data were prospectiv
Solid organ transplant recipients (SOTRs) are on lifelong immunosuppression, which may interfere with adaptive immunity to COVID-19. The data on dynamics and duration of antibody response in SOTRs are limited. This longitudinal study examined the longevity of both anti-spike (S)- and anti-nucleocapsid (N)-specific IgG antibodies after COVID-19 in SOTRs compared to matched immunocompetent persons.
Artificial intelligence (AI) has shown promising results in digestive endoscopy, especially in capsule endoscopy (CE). However, some physicians still have some difficulties and fear the advent of this technology. We aimed to evaluate the perceptions and current sentiments toward the use of AI in CE. An online survey questionnaire was sent to an audience of gastroenterologists. In addition, several
Background: Sepsis is a critical illness with high morbidity and mortality rates. Each year, sepsis affects about 48.9 million people all over the world. This study aims to illuminate how sepsis survivors experience sepsis and the impact of sepsis, as well as the health-related quality of life thereafter. Methods: An interview study with eight sepsis survivors was carried out in Sweden with an ind
Gene fusions have been discussed in the scientific literature since they were first detected in cancer cells in the early 1980s. There is currently no standardized way to denote the genes involved in fusions, but in the majority of publications the gene symbols in question are listed either separated by a hyphen (-) or by a forward slash (/). Both types of designation suffer from important shortco

Background Technological advancements over the last decades have resulted in an increased degree of digitalisation within as well as in between companies around the world. As a result, requirements on companies in general are growing and global competition is steadily increasing. One area for which this is highly relevant, and for which there is still a lot of potential for improvement, is industr
The landscape composition in Sweden has drastically changed during recent years. Intensified farming and forestry has led to reduced areas valuable for biodiversity and a decline of biodiversity across many organism groups. In Sweden almost 30% of all day-living butterflies are considered threatened. Habitat creation as a by-product of anthropogenic activities may provide new habitats for species
Chitosan films for food packaging applications were prepared from shrimp and cricket chitosan, enriched with Schisandra chinensis extract. Physicochemical and antibacterial properties of the films were studied and compared with references studying similar chitosan films. Chitosan is a biodegradable polymer, mostly harvested from shells of crustaceans, which has been studied for packaging applicati
A recent publication introduced a new way to define all k-step linear multistep methods of order k and k+1, in a parametric form that builds in variable step-size. In this framework it is possible to continuously change method and step-size, making it possible to create better behaving adaptive numerical solvers. In this thesis general numerical solvers based on this framework have been implemente
I alla industrier där partiklar behandlas i torra prover är segregering ett stort problem. Segregering kan ske vid olika steg i processen där partiklarna i fråga till exempel transporteras, blandas eller bara lagras. Det uppskattas att uppemot 30 % av all fördröjning i processer sker på grund av segregering av partiklar(Johanson, 2014). Detta leder till kritiska konsekvenser för ett företag så somSegregation is a well-known process problem that may cost companies quality and time. The aim of this project was to establish a fundamental understanding about sifting segregation by using the sifting segregation tester described in the ASTM International standard. In this work, Cellets and Suglets were used to study particles tendency to segregate at different weight ratios and different particl
Abstract The present thesis is concerned with the investigation of a metalorganic catalyst, a Pt complex used for C-C or C-N single bond formation in a cross coupling reaction. The investigated catalysts are used in a homogeneous reaction. In this study I have used chemical methods for the synthesis of the catalytic materials, a number of different techniques for the characterization of the catal
Vilken roll Hippocampus har i det episodiska minnessystemet är hett omdebatterat. En nylanserad teori, Competitive Trace Theory, stipulerar att strukturen ”kontextualiserar” minnen genom att skapa nya, multimodala minnesspår vid varje reaktivering av dem. Alla olika minnesspår har en gemensam, överlappande komponent samt en unik icke-överlappande komponent, och spåren konkurrerar om att slutligenThe role of the Hippocampus in episodic memory has been fervently discussed for a long time. A new model, titled ”Competitive Trace Theory”, holds that the role of this temporal lobe structure is to “contextualize” memory. This is achieved by the establishing of new, multi-modal memory traces every time the memory is reactivated. These distinct memory patterns all share a mutual component of the m
