Popular science summary: How do bacteria divide? Cell division is an absolute requirement for proliferation of all bacteria and results in the bacterium being split into two by a septum. FtsZ is a protein that plays a key role in bacterial cell division. In this project, one part of the FtsZ protein was investigated with genetic methods to understand how it affects the division process. Previou

Guantanamo Bay has been in the centre of medias attention for a while, especially since the United States in the year 2002 began placing taliban and al-Qaida detainees there. Much of the attention has concerned the United State's lack of compliance with the Geneva Conventions and the protection that it affords prisoners of war. This thesis takes a look behind the scene, in order to try to esta

Popular Abstract in Swedish Under 1900-talet har stora förändringar skett i synen på buddhistisk meditation. Från att ha varit en övning som bara ägt rum på kloster och bland ett fåtal munkar, har både ordinerade lärare och lekmannalärare börjat lära ut meditation till lekfolk. Meditation har kommit att framställas som själva hjärtat i buddhistiska traditioner, och som det element som kan isolerasThe purpose of this study is to investigate how a religious tradition changes when transposed to a new context: how it is received and incorporated in its new context and how individuals in Sweden perceive and make use of this tradition. This is done by highlighting the development of insight meditation, Vipassana, and more specifically, the Burmese practice lineage originating from the Burmese la

Popular science summary Are drugs only drugs for human being? An experiment to see if some of the anthropogenic pharmaceuticals are toxic contaminants for the aquatic environment. All kinds of pharmaceuticals have been using widely and the amount has been increased significantly during the last few decades. Concerns about the occurrence of pharmaceuticals releasing into different matrixes of th

In this project the aim was to design a concrete 3d printer. This report focuses on the extruder part of the printer and the printing material. The basic principle of 3d printing is that it is an additive manufacturing technique, on the contrary to the traditional subtractive manufacturing techniques. The potential benefits of concrete 3d printing compared to the techniques that are used today are

Skadliga marina arter invaderar idag främmande habitat och ekosystem med en extrem hastighet. Dessa arter har haft en mycket stor negativ inverkan på många sårbara ekosystem runt om i världen och barlastvatten har identifierats som en av de största faktorerna bakom den snabba spridningen. Idag är den vanligaste åtgärden för att lösa problemet att byta barlastvatten ute till havs för att göra sig aHarmful aquatic species are today invading foreign habitats at an unprecedented pace. They have had a large negative impact on many fragile ecosystems of the world and ballast water has been identified as one the major culprits behind their fast spread. Today, the most common remedy used to combat the problem is exchanging ballast water in the open ocean to get rid of any organisms with the potent

Popular Abstract in Swedish Kritiskt sjuka patienter på intensivvårdsavdelningar (IVA) har ofta störningar i blodets levringsförmåga (koagulation). Kliniska tecken som blodpropp (djup ventrombos eller blodpropp i lungorna) och/eller blödning kan vara resultatet av aktivering och konsumtion av koagulationsfaktorer och koagulationshämmare. Disseminerad intravaskulär koagulation (DIC, som är en samtiCritically ill patients in intensive care units (ICU) often have coagulation disturbances. Clinical manifestations such as thromboembolism and/or bleeding may result from activation and consumption of coagulation factors and inhibitors. Disseminated intravascular coagulation (DIC) is a severe condition with an often-poor prognosis. Global haemostatic tests are inexpensive, widely available, and ma

Background and Objectives: Photodynamic therapy using 20% 5 aminolevulinic acid (5-ALA) has recently been introduced as a new tool in optical skin rejuvenation. The primary objective of this study was to optimize incubation time, the topical delivery mechanism (vehicle) and the concentration of 5-ALA by detecting the dynamic changes of normal skin after 5-ALA application. The secondary objective w

Giant planets migrate though the protoplanetary disc as they grow their solid core and attract their gaseous envelope. Previously, we have studied the growth and migration of an isolated planet in an evolving disc. Here, we generalise such models to include the mutual gravitational interaction between a high number of growing planetary bodies. We have investigated how the formation of planetary s

Purpose: The aim of this study was to assess the suitability of Gafchromic EBT3 films for reference dose measurements in the beam of a prototype high dose-per-pulse linear accelerator (linac), capable of delivering electron beams with a mean dose-rate (Dm) ranging from 0.07 to 3000 Gy/s and a dose-rate in pulse (Dp) of up to 8 × 106 Gy/s. To do this, we evaluated the overall uncertainties in EBT3

Throughout history, people have used products from different microorganisms and plants for many medicinal and nutritional applications. Chilli peppers have been used for spicing up food, but also for their pharmacological properties. They contain alkaloid molecules called capsaicinoids, which have been shown to activate and desensitise the heat receptor - Transient Receptor Potential Vanilloid typ

This presentation gives an overview of a peer learning model and academic support intervention named SI-PASS (Supplemental Instruction – Peer Assisted Study Schemes) in Higher Education in Europe. SI-PASS is a method of improving student performance in “difficult”, normally introductory, courses combining “how to learn” with “what to learn”. SI-PASS sessions are scheduled parallel to the regular e

Background: The development of new targeted alpha therapies motivates improving alpha particle dosimetry. For alpha particles, microscopic targets must be considered to estimate dosimetric quantities that can predict the biological response. As double-strand breaks (DSB) on DNA are the main cause of cell death by ionizing radiation, cell nuclei are relevant volumes necessary to consider as targets

BackgroundA specific eHealth device, a surf tablet, was developed for bridging between advanced in-hospital care and children’s homes. Since little is known about determinators for parental eHealth usage, the study’s aim was to explore if parents’ usage of the device was associated with their eHealth literacy, or their satisfaction with their child’s healthcare or with the specific surf tablet.Met

Purpose - This paper aims to explore the electronic design of the Touch Hand: a low-cost electrically powered prosthetic hand. The hand is equipped with an array of sensors allowing for position control and haptic sensation. Pressure sensors are used on the fingertips to detect grip force. A temperature sensor placed in the fingertip is used to measure the contact temperature of objects. Investiga

This thesis describes experimental studies of laser-driven particle acceleration. With the focused intensity of today’s high-power lasers exceeding 10^18 W/cm2,extremely high-gradient accelerators are possible. A number of experiments have been performed using two different laser systems, the Lund multi-TW laser and the Vulcan laser at CLF/RAL, UK, to study aspects ranging from laser system optimi

Popular Abstract in Swedish En vän till mig berättade hur hon hade köpt en färgglad t-shirt vid en resa till Indien. Första gången hon hade den på sig började det att ösregna och ett par minuter senare fanns det snopet nog mer färg i de kringliggande vattenpölarna än i tyget. Lyckligtvis har de flesta färger idag bättre kvalitet än så. De färger som används inom textilindustrin är utvecklade för aConsiderable amounts of water and chemicals are used in the textile industry, and the presence of dyes in the wastewater is a problem of environmental concern. Synthetic dyes are designed to resist light, water and chemicals to improve the quality of the textiles; however, these properties also contribute to their persistence in the environment. The existence of wastewater treatment plants in conn

Popular Abstract in Swedish Hur kan nattaktiva insekter se i mörker med fel sorts ögon? Majoriteten av alla dagaktiva insekter har en sorts facettöga som kallas appositionsöga. Appositionsögon är anpassade till ett liv med god tillgång på ljus ? nattaktiva djur har därför i princip alltid andra sorters ögon (superpositionsögon). Anledningen till att appositionsögon fungerar bäst på dagen är att dDue to our own preference for bright light, we tend to forget that many insects are active in very dim light. The reasons for nocturnal activity are most easily seen in tropical areas of the world, where animals face severe competition for food and nocturnal insects are able to forage in a climate of reduced competition and predation. Generally nocturnal insects possess superposition compound eye
