The Proton Exchange Membrane (PEM) fuel cell has been investigated for a long time, and is regarded as a new energy source for various applications, such as portable, stationary and automotive ones. However, due to the shortage of the infrastructure in the society, the high cost, the difficulty of the water/thermal management, etc., practical systems have not reached the general public, yet. Of t
Det här examensarbetet i geologi är en studie av ökensediment. Det är tvärvetenskapligt mellan geologi och ekologi. Sedimenten som har studerats kommer från en statlig försöksodling, El Hicha, på saltstäppen utanför El Akarit, 45 km norr om Gabes i södra Tunisien. Första steget i studien var att ta sediementprover på försöksodlingen där Ministry of Rural Engineering, Water and Forest odlar träd oc
In this thesis I explore the subject on how burial was used by Viking Age population of South-western Scania to express their social identity. As opposed to most earlier research concerning Viking Age burials I utilise regional, mourner-centred and practice-based approach. I am following observations conducted for burials in Denmark by J. Ulriksen (2011), focused on traces of deposition of burned
Greenhouses and nursery-gardens is an important business in Sweden, covering a land area of 3,0 million square meters in 2011. The downside of this otherwise blooming business is however the use of so called PPPs, plant protection products, which is connected to it. Historically the use of PPPs has been widespread and the handling has been conducted in an off-hand way. During the post-war time the
Popular summary Energy generation from renewable sources is one of the main issues to be solved for the 21st century. One of the most advanced technologies currently available is wind energy, which has a large potential onshore and offshore. However, in many cases wind energy is restricted to large wind parks with wind power plants sometimes exceeding heights of 100 m. The construction of large wi
Popular science summary: Do bacteria survive in humans by eating the defense molecules during the course of infection? Enterococcus faecalis (E. faecalis) is a pathogen that can be found in the human gut which causes a wide range of infections including urinary tract infections, cardiovascular infections and bacteremia (presence of bacterial cells in blood stream). These bacteria can also be fou
Critics maintain that there are a number of troublesome issues resulting from the construction sector’s way of operating and that these remain, despite widespread criticism and measures designed to change all of this. The construction sector’s and the critics’ manner of describing these problems fails to a large extent to take into consideration the way people function in connection with practical
The small heat shock proteins (sHsps) are a widespread class of molecular chaperones existing in all organisms. During heat stress the sHsps protect other proteins from unfolding and aggregation. In plants the sHsps play an especially prominent part of the stress response. In this thesis chemical crosslinking and mass spectrometric mapping of crosslinked peptides has been used to investigate the
The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctu
The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. This thesis project aims to monitor theheat exchanges between the snowpack and the ice surface on a non firn-covered glacier,on Foxfonna, Spitzbergen, Svalbard, and to draw the p
Stora Enso Nymölla is a pulp and paper mill mainly producing office paper. Their most well-known product is the MultiCopy paper. Every fourth year all large companies are by law required to present an energy audit. This can be done as one large report or by presenting smaller reports during the four-year period. Nymölla Mill has decided to publish short overviewing reports every year and combining
An alternative energy and chemicals must be found to meet the future demand. A possible source of renewable energy is plant oil since it has a close chemical structure to fossil oil with less refining requirement. However, vegetable oil has not made a significant contribution to replace fossil oil as an energy source because of high demand of fossil oil. It is possible to substitute fossil-based c
The product price given when producing offshore is not the entire truth and more companies decide to move their offshore production nearshore (Stentoft et. al, 2016). To measure the actual cost of producing many more parameters than visible costs needs to be taken account for. There are advantages as well as risks with outsourcing and costs can increase with distance such as quality issues, freigh
In our society, digital cameras are used for a countless number of different purposes. There are many components going in to making such a complex product but one could argue that the camera sensor and lens make out the heart of a digital camera. Axis Communications AB, founded in 1984, is a Swedish company which pioneered and specialize in digital network cameras. In 1996 Axis delivered the first
This master’s thesis focuses on pedagogy and aspects of learning and remembering within guided museum tours for people with dementia. We explore in what way learning and remembering are focused on and triggered during those tours and with the help of which pedagogical means. Furthermore, we discuss what place these tours have within the museum as an institution. In order to examine our questions a
This thesis analyses web statistics belonging to a national B2C e-commerce in retail. The purpose of the thesis is to investigate abandoned carts amongst logged in customers with at least one product added in to their cart and at least one visit to the payment page. Since the response variable "cart" is binary and we are studying the probability of a cart being abandoned, the suitable me
As the world is changing rapidly in many ways, competition is getting increasingly fierce amongst manufacturing firms. As such, it has become more and more important for companies to properly understand the needs of their customers in order to provide enough value to be sufficiently competitive. Providing delivery and installation services which might’ve been viewed as necessary evils before have

Children affected by the multisystem genetic disorder Hutchinson-Gilford Progeria Syndrome look prematurely aged, suffer from elderly-related conditions and die during adolescence due to cardiovascular complications. The cause of the disease is single point gain-of-function mutations in the LMNA gene, which encodes the lamin A and lamin C proteins, major components of the nuclear lamina. These mut
As CO2 builds up in the atmosphere causing global climate change (IPCC, 2022) trees have become an international symbol of combatting this, and for good reason. Trees take up CO2 which as a result combats these changes, and when these trees are cut down fewer individuals remain to take up the CO2 that we humans emit (Chapin et al., 2011). This means that clear-cut areas don’t act as the carbon sin
