Bumblebees (B. terrestris) were trained to fly through an experimental setup containing two tunnels which led to a single feeder. A variety of patterns were fitted onto the tunnel walls, each producing a different pattern of optic flow onto the retinae, in order to test for differences in flight behaviour and decision making as a response to the visual cues presented in the tunnels. The results sh

True geese are members of the bird family Anatidae which contain many waterfowl spe-cies with high relevance as natural hosts of Avian Influenza Virus (AIV). The closely re-lated mallard (Anas platyrhynchos) is the main host of AIV and has a robust immune sys-tem which is also the best understood among the Anatidae. Previous studies have shown that some species of geese are more susceptible to AIV

Owls (Strigiformes) are birds that typically have crepuscular or nocturnal activity patterns. Even though birds are known to have an exceptional visual system, less is known about specific adaptations to vision in dim conditions. Here, by using retinal transcriptome sequencing, the visual gene pathway has been analyzed in four owl species: Long-eared owl (Asio otus), Short-eared owl (Asio flammeus

Barley, Hordeum vulgare, is a commercially important crop plant mostly used as animal feed but also as human food where it serves as an important source of _-glucan and other nutrients. As populations are growing worldwide, early flowering cultivars can play a vital role to increase the production of barley to meet the increasing demand of this crop. We analyzed five early flowering mat-e mutants

Today's corporate market is characterized by tougher competition than ever be- fore. In a changing society, companies must be prepared to change and develop their brands to stay relevant. In order to meet consumer demands and expectations, companies reposition their brand. However, a company can only control the change of the brand's identity and not the brand's image, because the imag

Macrophages are innate immune cells involved in tissue homeostasis and immunity. They are phagocytes and provide the first line of defense to invading pathogens. Tumors are abundantly populated with macrophages and they are also involved in many autoimmune diseases. Since macrophages play a crucial role in homoeostasis and disease they have emerged as key therapeutic target. However, to manipulate

Ett växande antal studier rapporterar ett samband mellan minne och lukter. Den här studien ämnade identifiera effekter av samma och olika lukter vid inlärning och återkallande av minne samt undersöka skillnaden mellan goda och inte goda lukter. En så kallad old / new recognition task användes som minnestest där deltagarna (N = 32) tränade in 20 ord i testets första fas, för att sedan i en andra faA growing number of studies report relations between memory and smell. The present study aimed to identify differential effects of same and different smells on word learning and recognition memory, in addition to investigate the difference between pleasant and unpleasant smells. An old / new recognition task was used as a memory test, whereby participants (N = 32) studied 20 words in the first pha

Monoclonal antibodies represent an attractive approach for treatment of cancer. Phage display is a very powerful technique to display large antibody libraries, which can be used to isolate therapeutic antibodies. Panning of phage display libraries against cells generates complex antibody pools, and direct screening of such pools typically identifies high-frequent antibodies against highly expresse

Our bodies are defended by inborn protective strategies aimed against microorganisms, the so-called innate immune system. In this system, small peptide molecules characterized by positive charge serve as antibiotics. During allergic reactions, as exemplified hay fever and asthma, molecules named eotaxins are released. These attract a group of white blood cells named eosinophils to sites of inflamm

Leukemia involves uncontrolled proliferation of different types of blood cells. Accordingly, it is classified as Acute myeloid leukemia (AML), Acute lymphoblastic leukemia (ALL; which includes B cell and T cell – ALL), Chronic myeloid leukemia (CML) and Chronic lymphoblastic leukemia (CLL). Children are more prone to ALL while the other three forms of leukemia are more common in adults. Over the l

Implicit measures have started to gain attention in the attachment literature, as they offer a way to offer insight into information processing patterns, which may not be open to investigation otherwise. The aim of the current study was to investigate the role of supraliminal priming on ambiguous stimuli in individuals who reported high levels of attachment anxiety and avoidance, with a speci

Mitochondria are the main organelles in eukaryotic cells involved in energy production together with their role in other mechanisms including intermediate metabolism, calcium signaling and apoptosis. Due to their importance in the correct function of the cell, genetic mitochondrial disorders can present a wide variability of symptoms, such as epilepsy, skeletal and cardiac myopathy and intellectua

Money illusion was for a long time believed by most economists to be non-existent, despite previous large support for it, because it did not fit the neo-classical model of the rational individual. Using a survey to test students’ understanding of inflation as proxy for money illusion, this thesis aims to establish the existence of money illusion and develop an understanding of why some students ex

Abstract The retina is the inner most layer of the eye. It is responsible for conversion of light into an electrical signal that pass through the fibers of the optic nerve to the visual centers in the brain. Most of the neo-vascular retinal diseases lead to legal vision loss. Silver and gold nanoparticles have got a great interest in ocular research due to their anti-bacterial effects and their ab

På höghastighetslinjerna som planeras byggas i Sverige är det satt som mål att köra i 320 km/h. Att köra så pass mycket snabbare än det görs i dagsläget kräver ett kontaktledningssystem vars kontakttråd klarar av att vara stabilt och rakt uppspänt så att strömavtagaren kan gå jämt och inte orsaka att kontakttråden börjar svaja. Det resulterar i krav på att kontakttråden spänns upp med ett högre mo

This study relates to the transcription of foreign personal names into kanji in Japanese. The study is based upon a paper where Tokimoto & d’Arcais (2000) confirmed three working principles when natives transcribe place names written in hiragana: that jukugo reading will be preferred over juubako reading, that as few kanji segmentations as possible will be used, and that the names will be segm

The main goal of this project was to investigate how the thermal stability of two different types of polyhydroxyalkanoates; poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) were affected when washing them with acid solution. Initially, four different acids were used: citric acid, hydrochloric acid, formic acid and acetic acid. Citric acid gave the best results for both biop

Syftet med studien är att undersöka debatten om sex timmars arbetsdag mellan 2010-2017. Genom att använda diskursanalys undersöker jag hur debatten ser ut idag genom att analysera debattartiklar i svenska dagstidningar för att försöka förstå varför ingen vidare utveckling har skett vad det gäller arbetstidsförkortning i Sverige sedan 1973. Bourdieus teori om det politiska fältet erbjuder ett analy

This paper investigates empirical determinants of current account positions worldwide with a focus on the countries that started out as the European Monetary Union (including Greece that joined in 2001). Specifically, it addresses the question whether current accounts inside the Eurozone have reacted more sensitively to changes in macroeconomic fundamentals due to the facilitation of inter-country

Under 2016 sade ett stort antal barnmorskor upp sig kollektivt inom Region Skåne. Uppsägningarna var en protesthandling och del i en arbetsplatskonflikt som kretsade kring ökad återhämtning för att garantera barnmorskornas hälsa och patientsäkerheten. Uppsatsens syfte är att förstå hur och varför protesterna resulterade i kollektiva uppsägningar. Materialet består av kvalitativa intervjuer med bar
