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
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
Punktlighet och förseningar inom järnväg är något som står högt upp på agendan i dagens samhälle. Med en infrastruktur som är i ett stort behov av underhåll samtidigt som trycket på klimatsmarta transportlösningar bara ökar, blir punktligheten och framkomligheten inom järnvägen avgörande. Med en total punktlighet på ungefär 90% finns det mycket att göra. En av järnvägens infrastrukturproblem är spPunctuality and delays within the railway system are of utmost concern in today’s society. With an infrastructure in a dire need of maintenance and the increasing pressure for environmentally friendly transportation solutions, punctuality and accessibility within the railway system becomes crucial. With an overall punctuality rate of approximately 90%, there is much to be improved. One of the prob
A Warehouse Management System (WMS) is a software that tracks and manages warehouse activities. The first WMS was introduced in 1975 and today the WMS market is valued at over USD 3 billion. Most warehouses use one as quality assurance becomes unlikely plausible without software support. This thesis focuses on Company X, who are the third-largest manufacturer by revenue in their industry and a
Currently, policy makers put high attention in supplying global energy demand by focusing on 2°C policy; global temperature anomaly based on the global mean temperature of pre-industrial era (13.7°C). How to keep the 2°C policy at global scope is the main question in climate framework. It is widely believed that primary energy resources (mainly coal, oil and natural gas) with focus on shale gas re
BACKGROUND: Minimally invasive surgery is rapidly expanding globally, yet there is insufficient knowledge of how to scale this technology safely and equitably across diverse health systems. We aimed to identify health-system factors associated with safe implementation of minimally invasive surgery globally, using minimally invasive cholecystectomy as a tracer procedure.METHODS: We conducted a mult
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
In this work conformational studies have been performed on peptides from four different systems in an attempt to gain knowledge about their biological function. Circular dichroism (CD) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy in combination with distance geometry and restrained molecular dynamics simulations were the methods used. A detailed conformational study of a cyclic p
This thesis investigates the adsorption, decomposition and reactions of small molecules on flat, oxidised and vicinal surfaces of late transition metals. The main technique for these studies is high resolution core level spectroscopy (HRCLS). All the studies presented in the thesis are performed in Ultra High Vacuum (UHV). The articles can be divided into three groups. The first three articles dea
Popular Abstract in Swedish Förekomsten av hudcancer ökar i ljushyade befolkningsgrupper och hudcancer tillhör de cancergrupper som ökar mest i Sverige. De tre vanligaste formerna av hudcancer är basalcellscancer, skivepitelcancer och malignt melanom. Under 2013 utgjorde skivepitelcancer och malignt melanom ca 16 % av alla cancerfall som rapporterades in till Svenska Cancerregistret; över 6 000 faSkin cancer incidence is increasing in fair-skinned populations. The three most common skin cancers are basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and malignant melanoma (MM). A correct diagnosis is crucial for an efficient and tailored treatment for the skin cancer patient. The purpose of this thesis was to evaluate different aspects of the preoperative diagnosis of skin cancer. Th
In order to better assess the role of agriculture within the global climate-vegetation system, we present a model of the managed planetary land surface, Lund-Potsdam-Jena managed Land (LPJmL), which simulates biophysical and biogeochemical processes as well as productivity and yield of the most important crops worldwide, using a concept of crop functional types (CFTs). Based on the LPJ-Dynamic Glo
The characterization of naturally occurring mutations is one way to approach functionally significant domains of polypeptides. About 10 mutations have been reported in factor XIII (FXIII) A-subunit deficiency, but very little is known about the effects of the mutations on the expression or the structure of this enzyme. In this study, the recent crystallization of FXIII A-subunit and determination
