Host-virus interactions in archaea is a topic that still remains little explored. A recent study has revealed that the protein gp21 from SIRV2 (Sulfolobus islandicus rodshaped virus 2) induces cell gigantism and growth arrest in the archaeal host Sulfolobus islandicus LAL14/1 after being overexpressed. Remarkably, homologs of this protein have been found in a wide variety of viruses infecting arch
To continue the development of novel therapeutics to treat bladder cancer, a reliable model for preclinical testing of treatments and studying of the disease mechanism is essential. Ex vivo culturing of precision cut tumor slices (PCTS) provides a model that can retain the tumor architecture and its tumor microenvironment including the immune cell compartment, but data on PCTS based on bladder tum
With countries across the world finding pathways to counter CO2 emissions, sustainable mobility has become a critical topic for leaders, policymakers, and industries. The development of Battery Electric Vehicles (BEV’s) is seen as an important and effective way through which reliance on fossil fuels and thereby related CO2 emissions can be reduced. Statistics show that the number EV’s on the roads

I denna studie testades och utvärderades fyra membran mot varandra för användning i högtemperaturprotonutbytesmembranbränslecell (HT-PEMFC) applikationer. En fosforsyra (PA)-dopat polybensimidazol (PBI)-membran användes som en referens som den nuvarande state-of-the-art. Laddningsbäraren i detta membran är PA, och det finns fördelar med att byta från PA till jonisk vätska (IL) som laddningsbärare In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. The charge carrier in this membrane is the PA, and there are advantages in switching from PA to ionic liquid (IL) as t
Children do not have many spaces designed entirely for their needs in our world. This has inspired the concept of ‘A Child’s Garden City’. The idea includes research of how children can be included in design and the process of creating safer cities with their considerations in the center. This Master’s Thesis can inspire the relationship between growing natural vegetation, self-sustaining infrastr
A variety of excess material is produced in the processes used in the scrap-metal based steel industry. The largest stream of material, by volume, is steel slag. Since slag material has very different properties and wide differences in its chemical composition its usage can be found in different sectors. The increased understanding of slag and its properties has made companies less prone to divert
Sen den 1:a januari 2015 regleras för första gången innehållet i exploateringsavtal i Plan och bygglagens 6 kap 40 §. Hur paragrafen ska tolkas och tillämpas i praktiken råder det stor oklarhet kring. I arbetet utreds hur paragrafen ska tolkas, med fokus på vad som är ”nödvändiga åtgärder” för genomförandet av en detaljplan samt vad som är ett ”rimligt förhållande” mellan en exploatörs åtaganden oSweden’s Planning and Building Act has been updated several times since it was introduced, and the most recent updates entered into force on 1st January 2015. One of the changes is that for the first time, in the 6th chapter 40th section, the contents of land development agreements are regulated in law. However, how the new law section shall be interpreted and used in practice is unclear. This mas
The response to climate change in cities has proliferated over the last few decades, and progressive climate action at the local level is now ubiquitous. More specifically, local climate action often comes in the shape of ‘climate change experiments’, radical innovations at the local level designed to respond to the imperatives of mitigating and adapting to climate change in the city. This thesis
Sweden’s road traffic is responsible for a great part of the emissions of greenhouse gases in the country. Conventional vehicles, driven by fossil fuels, have low efficiency and emits environmentally destructive particles. Electric vehicles can be the solution! Electric vehicles have no local emissions while driving and the electric motors of today have an efficiency of above 90 %. But there are s
Background: Scoliosis is a condition where a person's spine is curved and rotated in three dimensions. In severe cases, surgery is needed to straighten the spine. Before such complex procedures, meticulous planning is needed. By performing a CT-scan, images of the spine can be acquired. From these images, it is possible to segment the spine in three dimensions to facilitate the preparation. Ho
The development of the water-borne microbiome in newly installed polyethylene pipes of a non-chlorinated drinking water distribution system was studied over a period of six months. Water samples were taken from two identical newly installed pipes (“NP1”, “NP2”), as well as from a reference point at equal distance (“DS1”). These water samples were filtered and had the DNA extracted using FastDNA SP
Begreppet psykisk misshandel kan vid första anblick tyckas svår att greppa. En ojämn maktrelation kan förstås som kärnan av begreppet och för barnrätten blir därför relationen mellan barn och förälder central. Idag finns begreppet i 2 § LVU och kan leda till tvångsvård, under förutsättning att barnets hälsa eller utveckling påtagligt riskerar att skadas. Arbetets syfte har varit att närma sig begThe term psychological abuse may intuitively seem difficult to grasp. An uneven power dynamic can be described as the core of the term and relating to children’s rights it centers around the relation between a child and their parent. Today, the term is found in the second paragraph of the Care of Young Persons Act and can lead to compulsory care, if there is a significant risk to the child’s healt

Title: Chillchain for cut flowers ? how the distribution works. Author: Anna-Maja Svarén, student at Lund Institute of Technology, mechanical engineering. Supervisors: Annika Olsson, Department of Design Sciences. Bengt Sahlberg, Bioett AB. Problem: How does the distribution of cut flower works regarding temperature, losses, responsibility, complaints, packaging and weak points? Purpose:
All around the world is the form of the built environment playing a significant role in either enabling or inhibiting outdoor activities. When it comes to winter and Winter cities, it is a challenge how to enable and encourage outdoor activities and soft mobility as the harsh conditions often make it uncomfortable to spend longer periods of time outdoors. A major urban design challenge in Winter
The unfolding COVID-19 pandemic, and the unprecedented social and economic costs it has inflicted, provide an important opportunity to scrutinize the interplay between the resilience of small and medium-sized enterprises (SMEs) and the resilience of the communities they are embedded in. In this article, we articulate the specific ways that SMEs play a crucial, and underappreciated role in building
BACKGROUND: An intact umbilical cord allows the physiological transfusion of blood from the placenta to the neonate, which reduces infant iron deficiency and is associated with improved development during early childhood. The implementation of delayed cord clamping practice varies depending on mode of delivery, as well as gestational age and neonatal compromise. Emerging evidence shows that infant
Hirshfeld atom refinement (HAR) provides a more realistic interpretation of crystallographic data than the standard independent atom model (IAM) by using aspherical atomic form factors derived from quantum mechanical (QM) calculations. With this aspherical description, it is possible to obtain improved atomic positions, atomic displacement parameters and correct bond lengths even for hydrogen atom
