Stamcellsforskning har på senare tid lett till förhoppningar om att bota alla möjliga sorters sjukdomar. De stamceller som är mest flexibla och därför mest användbara finns i embryo. Att få tag på mänskliga embryon kan dock både vara dyrt och moraliskt problematiskt. Därför har forskare försökt att istället omprogrammera celler från vuxna individer. En sådan teknik som nyligen tagit fart är direktRegenerative medicine offers a great prospect for curing diseases. Scientists are using direct conversion to reprogram fibroblasts, a kind of skin cell, into neurons in an attempt to cure Parkinson's disease. Even though successful conversion has been done with embryonic cells, a more practical method for future treatment would be to reprogram cells directly from the adult individual. It has h

Slam, nästan som vatten? För många industrier är slam en restprodukt och olägenhet som kostar både tid, energi och pengar att forsla bort. Med tanke på att slam innehåller en väldigt hög vattenhalt är det rimligt att tro att det är i det närmsta ofarligt, men så är ej fallet om det är obehandlat. Den lilla procentuella andelen på mellan 2-7 % fast material i slam kan starkt påverka miljön. TilIndustrial sludge is a waste product generated in various industrial processes. Depending on the industrial process itself, the sludge can contain a lot of different elements. For example, organic content is harmful for the aquatic environment as it is oxygen-consuming. Companies must therefore have authorization to discharge the sludge or get it treated by wastewater treatment plants. Due to a hi

Bakgrund: personer med någon form av demens på särskilda boenden, kan uppleva sig understimulerade vilket leder till en frustration, även för sjuksköterskan. Sjuksköterskans uppgift är att minska lidande och främja en personcentrerad omvårdnad varvid vårdhundar kan vara ett redskap i arbetet att skapa en meningsfullhet i tillvaron och ökad livskvalitet. Syfte: Sammanställning av befintliga forskni

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

Tropical cyclones influence processes within the carbon cycle on different time-scales. Forested ecosystems suffer windfall and long-term impacts from tropical cyclones, leading to the release of CO2 to the atmosphere. The coarse woody debris created by extreme wind speeds and landslides brought on by tropical cyclones can leave a forested ecosystem via riverine channels and end up in the ocean, w

Om dina ögon vore lika känsliga som astronomers toppmoderna teleskop skulle du kunna se långa band av ljus när du kollar upp mot himlen. Dessa band kallas stjärnströmmar och befinner sig i yttre delen av våran galax, Vintergatan. Strömmarna skapas från en klump av stjärnor, t.ex. en dvärggalax, medan de roterar runt Vintergatan. Det som händer är att stjärnor slits loss från klumpen och dras ut tiThe orbital approximation for stellar streams is the assumption that all stars in a stream can be described as following the same orbit. In this thesis, I evaluate this approximation as a method for constraining the potential of the Milky Way. I wrote a program in MATLAB which integrates the orbits of test particles in a potential model which resembles that of the Milky Way's halo and disc. Th

The aim of this thesis is to gather existing literature regarding the challenges senior human resource managers face in multinational corporations when managing a global workforce, as well as to discover the strategies that are used within the field of international human resource management. The systematic literature review revealed several main challenges and strategies and by building on those

The life cycle and behavior of free-living soil nematodes is highly dependent on environmental factors such as temperature and soil moisture, fluctuations leading to significantly lower development and activity rates, dormancy and/or mortality. This literature review summarizes present knowledge about free-living soil nematode temperature and moisture requirements, as well as the commonly accepted

Gas cooling is a technique used by firefighters to create a safer work environment inside a compartment fire. By spraying water into the smoke layer, the smoke layer temperature will decrease significantly. Next to the lower temperature, the flammability of the smoke layer will also decrease. Due to the cooling of the fire gases, the smoke layer may contract. This work focused on different parame

Children who grow up with a parent with an addiction and/or mental illness are at higher risk of developing the same disorder. There are children who even when growing up under rough conditions succeed to overcome their childhood and grow up to be “normal” citizens. These children have a high level of resilience and are usually referred to as Superkids. The aim of this study was to understand what

Syftet med denna kvalitativa studie har varit att genom en komparativ analys av Supplementary instruction (SI) och ämnet Ensemble på gymnasiet, jämföra undervisningskulturernas karaktär samt dess inverkan på elevernas upplevelse av bedömning. Studien har också ämnat identifiera om och i så fall hur eleverna ges utrymme att utveckla icke-kognitiva förmågor inom dessa miljöer. Med en hermeneutisk anThe purpose of this qualitative study has been to investigate the teaching cultures within Supplementary instruction (SI) and the subject Ensemble in upper secondary school. Through a comparative analysis of these learning environments, the aim has been to seek understanding of the pupils’ perception of assessment. The study has also intended to identify if, and in that case show how, the pupils a

Purpose: The purpose is to explore the phenomenon of utilizing corporate museums in internal branding, in order to understand what they are, how they are used and why in the context of strategic brand management in general and brands with a heritage in particular. Methodology: A qualitative multiple case study with a constructionist and inductive approach has been executed. The case companies rep

Investments are essential to any economy. Therefore, governments aim to increase the level of total investments done within a country. Investments improve the economy and the productivity of the country. For this reason, it is important to understand which factors can influence investments on a national scale. The primary aim of this study is to investigate factors that could reasonably be exp

A study is carried out on the ventilation strategies for road tunnels in different countries and consequences using fixed fire fighting systems (FFFS). The type of ventilation strategy for road tunnels can ensure the safety of people during the evacuation stages and protection of the rescue services during their intervention of the fire. Ventilation strategies vary from country to country and ther

Self-driving cars have the potential to revolutionize individual mobility. Before this can happen, however, they will have to overcome a series of hurdles, one of which will be to overcome resistance among potential users. Previous research about resistance towards self-driving cars has primarily revolved around demographic characteristics that correlate with a higher likelihood of resistance. Thi

The aim of this paper is to explore which skills and mindsets are necessary for successful leadership in the digital era. It is written for IKEA who are interested in remaining at the forefront of their industry by understanding how digitalisation affects their business and how to make the most of the opportunities it brings, one aspect of which is leadership. There is a gap in the existing knowle

With recent advances in the field of ultra cold atoms one can, by trapping atoms at low temperatures by laser beams, simulate systems which can be adequately described by single-band lattice Hamiltonians. Also, due to the high parameter tunability of the experimental setups, lattice disorder can be introduced in a con- trolled fashion in these systems. This thesis considers disordered/ordered inte

The time-ordered linear density response function is examined in a model study. Two model dimers are considered; one with one orbital per site and a second one with two orbitals per site. The one-orbital case has U0, the on-site Coulomb interaction, as the only parameter and is solved analytically. The two-orbital case has parameters U0, the upper orbital non-interacting eigenenergy ε1, and the ho
