De senaste åren har tarmfloran blivit mycket omtalad eftersom den visat sig spela en viktig roll för hälsan, och till och med kopplats till vissa sjukdomar. En sådan sjukdom är celiaki, en livslång inflammatorisk sjukdom som drabbar i snitt 1.5% av världens befolkning. Om en person med celiaki får i sig gluten, svarar deras immunförsvar med en inflammatorisk reaktion. Detta i sin tur aktiverar celCeliac disease is a chronic inflammatory disorder of the small intestine, triggered by gluten in genetically susceptible individuals. The inflammatory and autoimmune aspects of this disease involves the intricate interplay of the immune system and gut microbiota, and celiac disease has repeatedly been associated with dysbiosis of the gut flora. Probiotics have been suggested as an alternative trea

Patients with Cystic Fibrosis develop chronic infection in the lungs. Achromobacter xylosoxidans is an opportunistic pathogen that is frequently found in the lungs of the patients. In the present study, phylogenetic analysis on whole genome sequences from patients with A. xylosoxidans was performed and libraries were prepared with information on genetic variation both in the entire genome and in c

Aktivitet hos humlor och fjärilar Vad är egentligen aktivitet? Tänk på det som om när du funderar på att gå och handla. Du vill inte handla när alla andra gör det för då kommer det vara stor konkurrens när du väl ska betala i kassan. Samtidigt vill du inte komma försent till affärerna och riskera att varan du ska handla tagit slut. Så frågar är: När är den optimala tiden att handla? Lite på samBiodiversity of bumblebee and butterfly species in the agricultural landscape are declining and conservation actions are needed. Conservation measures have the potential to be more effective if they are conducted at the right time. Previous studies have investigated the patterns of activity of bumblebees and butterflies. However, they have failed to look at differences in activity depending on spe

Thesis purpose The purpose of our thesis is to explore how and why consumers with low prior knowledge educate themselves about sports supplements and what effect gender has. Methodology Our research derives from a pragmatic orientation. We conducted a multi-method qualitative study, combining observations and interviews in order to explore and understand the online customer journeys of consumers

The present thesis focused on analysing the recent opening of the South Korean cosmetic industry to the Western world, in combination to a trade of beauty ideals, facilitated by social media and the internet. More specifically, the study focused on three main levels of inquiry. Firstly, understanding how the South Korean beauty industry advertises its products abroad through social media outlets;

In September 2017, freelance journalist Shiori Itō filed a lawsuit against the prominent TV reporter Noriyuki Yamaguchi for sexual assault. The somewhat obscure investigative and legal handling of the case prompted notable international media coverage, however domestic coverage has been comparatively scarce and apathetic. The media’s act of presenting news in a certain manner is referred to as med

The electric vehicles are increasing in popularity year by year. However, the market demand for such technology is still moderate and most traditional actors within the automotive industry are having a hard time adapting to this new stage. What poses threats to the survival of some actors can simultaneously become a great opportunity for the emergence of new major players. This paper looked at the

Biological invasions and their underlying mechanisms have become major issues in ecology, conservation and evolutionary biology. In order to better understand the factors determining colonization and invasion success, I obtained common-garden data from more than 1000 greenhouse-grown plants of two alien grass species, Eragrostis minor and E. multicaulis, derived from about 30 sites per species in

Vattenmolekylers rörelse: ett mått på små förändringar i hjärnan Visste du att bättre förståelse för nätverket av nervtrådar i hjärnan kan uppnås genom att mäta vattenmolekylernas rörelse? I denna studie användes detta för att undersöka om det finns förändringar i hjärnan hos personer med den autoimmuna sjukdomen SLE. Hur kan vattenmolekylers rörelse användas för att förstå hjärnans uppbyggnad? Systemic Lupus Erythematosus, SLE, is a disease with a large variation of symptoms. Some patients have neuropsychiatric symptoms, such as cognitive dysfunction and epilepsy. The classification of patients into NPSLE, with neuropsychiatric symptoms, and non-NPSLE, without these symptoms, is uncertain. Studying the white matter microstructure of SLE patients and comparing this with healthy controls

Syfte: Syftet med denna uppsats är att undersöka hur unga svenska kvinnors reaktioner till kvinnligt könsdiskriminerande annonser respektive icke könsdiskriminerande annonser skiljer sig åt och hur reaktionerna i sin tur påverkar deras attityd till varumärket bakom annonsen. Metod: Studien tar en deduktiv forskningsansats där den empiriska datan samlas in genom en tvärsnittsdesignad enkätundersö

The increase of brownification in surface waters has been a problem for rivers and lakes from the northern hemisphere. The main factors of this water brownification are the increase of dissolved organic matter and iron in water bodies. This study aims to assess the contribution of groundwater flow and surface flow from Bolmsö Island to the water balance of Lake Bolmen, Sweden. This assessment help

The presence of birds in an ecosystem is often a good indicator of the overall biodiversity. Since birds can be hard to see, their sounds are often used instead to measure their presence. To automatically detect birds the most common method is to use a time-frequency representation together with a convolutional neural network. The most used time-frequency representation is called the spectrogram.

The world of data is changing fast, while data always have been present in the world of computer science the importance of data has in the last couple of years grown, and it does not seem to be slowing down. The data usage is steadily increasing and the amount of data is growing, as well as the ever expanding amount of devices that produce data, especially in fields such at IoT and cloud computing

Konsten att släktforska på en 1mm stor vattenloppa En vattenloppa är ett litet plankton som vanligtvis lever i sjöar, men ett fåtal bor i den marina miljön. En speciell vattenloppa, Penilia avirostris, kommer ursprungligen från varmare områden runt ekvatorn, men har sedan 1990 observerats i Nordsjön och därefter (2003) påträffats i Öresund. Men hur kan en liten vattenloppa, som lever i varmare vaPenilia avirostris is a marine Cladoceran species typically occurring in tropical and subtropical regions. Several studies have revealed a global expansion of the species and an invasion of the North Sea since 1990. By analysing the phylogeny of the species, it could be possible to unveil its origin and direction of expansion. This molecular method has been applied for Cladoceran systematics with

In the first years of their independence from the Soviet Union, the political landscapes in Kyrgyzstan and Uzbekistan were both characterized by autocratic regimes. While Kyrgyzstan eventually freed itself from the governments firm retention of power, Uzbekistan’s president remained in charge up to his death in 2016. Exploiting the fact that the border between the two countries only materialized aft

Jag har analyserat huvud- och spårelementkoncentrationer i plagioklas från en norit-anortositintrusion, Älgön, Hakefjorden vid Sveriges västkust med syfte att fastställa intrusionens magmatiska ursprung, magmans utveckling och dess transport upp genom jordskorpan.
