Abstract: Background. In clinical heart transplantation, the most common method used to preserve the donor heart is cold flush perfusion with a cardioplegic solution, e.g. St. Thomas Solution. This method gives safe preservation for up to 4 hours. Methods. In organ baths, vessels segments of porcine coronary arteries were used to study the smooth muscle contractility and endothelial dependent an

There is a recurring argument among scholars concerning entrepreneurship education: some argue that it lacks value, others disagree, pointing out that concrete outcomes can be achieved by a combination of academic learning while obtaining practical experiences at the same time. There have been studies of both aspects but without a clear conclusion. In this study, we conduct personal interviews wit

Popular science summary: NADase – a way to avoid immune system activation? Streptococcus pyogenes (S. pyogenes) are bacteria that cause many different kinds of diseases in humans, for example strep throat, scarlet fever and necrotizing fasciitis, the ”flesh-eating disease”. An infection with this type of bacteria can also lead to heart and kidney damage, thought to be caused by our immune system

Popular science summary: Mammals are born with relatively immature digestive and immune systems. The functional maturation of these systems takes place at weaning (dietary change from milk to solid food). The activation of immune system occurs due to new antigens from new diet and changed microflora. It has been shown in rat model that activation of adaptive immunity can influence functional deve

This project work covers the design and construction of a new probe system for hot gas analysis in an entrained flow gasifier. The aim is a probe that can be used more flexibly than the present system. As a further aim, the condensation of trace materials has to be prevented. First, a short overview over current techniques to analyse the product gas in a gasification process is given. Continuing,

Popular science summary: The European silver eel oceanic migration During the past 30 years the population of the European silver eel has been declining dramatically. This is a commercially important species and several action plans have been established but little information about the biology of the European eel is known. During the EELIAD project female silver eels were electronically tagged

Popular science summary: New approaches for treating lakes with ammonia pollution Extract of Yucca shidigera, a desert plant, has been used in aquaculture to control ammonia in the water. Microalgae has been proved effective in removing ammonia and phosphorous from wastewater of agriculture and aquaculture. Therefore, it is possible that they could remove ammonia from lakes. Hence, several fish t

Popular science summary Habitat selection and chick survival of Eurasian Golden Plovers pluvialis apricaria altifrons during a lemming peak year in southern Lapland (Sweden) Aided by radio-telemetry, this study investigates the factors involved in the survival of Eurasian Golden Plover chicks and variations in habitat selection, home ranges and diet at different times through the pre-fledging pe

Popular science summary Hodgkin’s lymphoma (HL) is a common B cell lymphoma of the Western world and the therapies used to treat it have considerable side effects. Epstein Barr Virus (EBV) infection is associated with the pathogenesis of HL, though little is known about its contribution. B-lymphocyte undergoes two rounds of differentiation; first in the bone marrow where it becomes a Naïve B cell

Begreppet mentalisering avser förmågan att förstå sig själv och andra utifrån mentala tillstånd. Studiens syfte var att undersöka denna förmåga hos personer med erfarenhet av borderline personlighetsstörning eller ätstörning. Metoden var Affektmedvetenhetsintervjun själv-annan. Intervjuerna analyserades med tematisk analys och sex stycken teman identifierades. Resultaten visar att kroppsliga respeMentalization is a term that refers to the ability to understand one’s own and others minds as minds. The aim of this study was to examine this ability among people who either are or have been diagnosed with borderline personality disorder or eating disorder. The semi-structured Affect Consciousness Interview- Self/Other was used to collect data. The data was analyzed using thematic analysis and s

During the summer of 2013, A-hus will deliver housing in four floors to Derome Mark & Bostad exploiting land in Svedala. One of the technical challenges in these houses is to design the connection between the two outer wall elements and the floor structure. The current proposal is to connect the three elements using a 400 mm long screw that is toe-screwed through all three elements. This metho

The goal of the project is to identify and analyze different solution methods and to see how they should be applied to an industrial problem. The problem that will be examined is assembly of screws in a disc. The solution uses a Pacdrive system which is used to control and synchronize the servo motor. The operation of the motors will be done with an electronic cam that is completely virtual. In th

Cardiovascular diseases are accountable for almost 50 % of the mortality number in Europe which is why research on its causes is highly prioritised. For practical and ethical reasons, in vitro study models are of high importance to enable research on cardiac abnormal behaviours. To meet this issue, researchers from Imec, Belgium, developed Neuray-II, the second generation of a biocompatible chip w

Populärvetenskaplig sammanfattning Det finns två huvudsakliga typer av diabetes, typ 1 (T1D) och typ 2 (T2D), samt flertalet mindre vanliga former av diabetes t.ex. MODY. I bukspottkörtelns β-celler produceras insulin, vilket är det mest centrala hormonet i regleringen av blodsockret som verkar genom att öka cellernas upptag av socker från blodet. T2D, tidigare kallad åldersdiabetes, beror till sABSTRACT The prevalence of diabetes keeps increasing around the world, of which type 2 diabetes (T2D) accounts for 90%. Both lifestyle and genetic factors contribute to pathogenesis of the disease. A significant proportion of the basic research on T2D focuses on the genetic components and susceptibility genes especially on the insulin secretion. Herein, we functionally examined 4 T2D candidate ge

En ökande trend av tvärvetenskapliga forskningsprojekt har gett upphov till en uppsjö litteratur i ämnet. Denna försöker på olika vis belysa problem som kan uppstå vi denna typ av samarbeten och ger mer eller mindre handfasta förslag på hur dessa på ett effektivt vis kan överbryggas och medvetandegöras. Förvånansvärt lite utrymme lämnas åt fördelarna med tvärvetenskapligt arbete. Vad är det som dr

Abstract Failures in achieving the 2010 goals of slowing down or halting the loss of biodiversity, and the setting of new biodiversity targets set for 2020, stress an urgent need to expand current reserve networks and to improve their effectiveness in protecting species and habitats. Habitat suitability models, and derived maps from them, are among the broadest used tools for identifying the ecol

Populärvetenskaplig sammanfattning Strukturbioinformatik och datorgrafik Proteiner bygger upp våra muskler, hud, hår m.m. och fungerar som katalysatorer (enzymer) för reaktioner som behövs för livet. Våra gener kodar för proteiner som utför funktioner i kroppen. Bioinformatik handlar om att studera det genetiska materialet hos människor och andra organismer. Strukturbioinformatik riktar in sig Abstract This Master Thesis explores a variety of approaches to protein structure comparision : CLICK, BetaSuperPoser, MAMMOTH, Minkowski Sum Boundary Calculation, 3DSurfer / Zernike Descriptors, Spherical Harmonics, D2 Shape (distance histogram) and ProBiS. The methods are categorized according to how they function and the meaning of their output parameters, in particular RMSD, is discussed. We

The purpose of this work is to give an insight into how vocal students describe their desire to sing and practice singing, and to find out what the students get feedback from their surroundings in voice and in practice and how feedback affects them. The study would thus create an understanding of what motivates students to sing and practice singing. The study is based on qualitative interviews wit

Creating a musical – Participants’ experiences of the Lovewell Institute’s creative process This study utilizes qualitative research methods in order to explore the experiences of students who participated in Lovewell Institute’s creative musical theatre workshop in Oskarshamn, Sweden 2012. The two main methods used are participative observation of the workshop and interviews with five of the stud
