Classical evolutionary life history concerns questions such as optimal timing of maturation, life span and number of offspring. These questions have mostly been studied theoretically under the assumption that the environment is stable and without taking into account frequency and density dependence. Life history theory is the basis for my thesis, in which I have studied the evolution of different
Öresundsregionen är en mycket aktiv region med över tjugotusen människor som arbetspendlar dagligen. Rent fysiskt är det idag lättare att pendla över Öresund än förr, tack vare Öresundsbron. Det finns dock andra hinder. Sveriges regler för sociala avgifter och på inkomstskatteområdet skiljer sig en hel del från Danmarks och denna diskrepans kan ge upphov till vissa problem. Uppsatsen är inriktad pThe Öresund region is a very active region with over twenty thousand people commuting daily across Öresund. Nowadays it is, physically, easier to commute than before, thanks to the Öresund bridge. There are however other remaining obstacles. The legislation of the social insurance scheme and the income tax area in Sweden is different from the corresponding areas in Denmark and the discrepancy may
Uppsatsens syfte är att undersöka återförsäljares uppsägningsskydd och rätt till ersättning vid avtalets upphörande. För ett företag som önskar etablera sig på en ny marknad gäller det att välja rätt exploateringsmetod. Ett alternativ är då att utse en representant som säljer produkten på den nya marknaden. En lokal representant som känner till marknaden och eventuellt redan har ett etablerat försThe purpose of this essay is to examine the retailer’s dismissal protection and the right to compensation for termination of contract. For a company who wishes to establish themselves in a new market it is important to choose the right development approach. An alternative is then to appoint a representative who sells the product in the new market. A local representative who knows the market and po
In the automotive industry, it is common that the customers provide the suppliers with the necessary packing material needed for delivery of the goods. The reason for this is that it makes the handling and unpacking of incoming goods at the customer easy, but it also makes sure that the quality of the packing material is high, and that the transportation damages of the goods are minimised. It shou
Arbetet är utfört åt skogsforskningsstationen Mógilsá som ligger strax norr om Reykjavik. Forskningen inom Mógilsá bedrivs inom delar av eller för hela Island med inriktning inom exempelvis dendrokronologi, proveniensförsök, och studier av insekter. Sedan 1900-talets början har inplantering av exotiska trädarter blivit allt vanligare och i en allt större skala. Syften med inplanteringen är bland aThis study was made in an attempt to give the forest research centre Mógilsá a produced tetratherm map and a better understanding of how topography and temperature influence the growth of two tree species. The digital tetratherm map model, covering the northern part of Iceland, was developed to investigate the correlation between tetratherm and the growth of Picea sitchensis and Larix (sukaczewii
The maritime transportation of hazardous cargo has created a sometimes intense dispute between the shipping industry and coastal states. The arguments feeding this discussion are the right of innocent passage, claimed by shipping states, and on the other hand, the obligation to protect the environment stressed by coastal states. Two sets of rules, both codified in international law, stand in confl
In Swedish tax law there is a connection between the accounting of a company and the taxation of the same. In this essay I describe and discuss this connection. The essay is divided into two parts - one part describing the connection of today, and one part discussing the connection of tomorrow. To understand the connection between the accounting and the taxation, one must know the fundamentals of
Background: Energy citizenship has emerged as a concept which attempts to capture the new role envisaged for urban citizens as engaged and active in the energy transition. However, exactly how to successfully engage energy citizens requires more research and this article aims to contribute to this knowledge gap. The article presents a new methodology, ‘Walking with Energy’, which seeks to (re)conn
Background: Incisional hernia remains the most common complication of open abdominal surgery. The aim was to investigate whether a reinforced tension-line suture combined with standard 4: 1 small-bite closure reduces the 3-year incidence of computed tomography-detected incisional hernia in open colorectal cancer surgery. Methods: Patients aged > 18 years, scheduled for colorectal cancer resection
BACKGROUND: Opioids are still widely prescribed to long-term pain patients although they are no longer recommended for long-term treatments due to poor evidence for long-term efficacy, risks of serious side effects, and the possibility of inducing opioid hyperalgesia. In a Cochrane study from 2017, the authors identified an urgent need for more randomized controlled trials investigating the effici
Background: The Swedish National Cataract Register (NCR) collects data on cataract surgery outcomes during March, including patient-reported outcomes using the Catquest-9SF questionnaire for over 11 years. Previous studies from NCR have shown that the preoperative visual acuity has improved over time. The main purpose of this study was to evaluate the Catquest-9SF Rasch scoring performance in this
At the emergency department (ED), it is important to quickly and accurately determine which patients are likely to have a major adverse cardiac event (MACE). Machine learning (ML) models can be used to aid physicians in detecting MACE, and improving the performance of such models is an active area of research. In this study, we sought to determine if ML models can be improved by including a prior
This research project was inspired by the increase in popularity of hillwalking and the problem of the lack of monitoring and maintenance of upland paths which may lead to serious deterioration of those paths. Wicklow Mountains National Park (WMNP), just south of Dublin City in Ireland, has a large network of mostly informal upland paths. A comprehensive baseline survey of many of these paths was
The main focus of this Master Thesis is the development and evaluation of an actuation system that controls a variable compressor for the automotive industry. This variation allows the compressor to produce different boost pressures on demand. Before the development process could start a theoretical analysis of the different forces acting on the system were conducted. These analyses consisted of a
De stora häxprocesserna i Europa ägde rum under 1400- till 1700-talet. Framställningen avser att besvara hur den juridiska processen mot häxeriet var utformad samt förklara hur häxförföljelserna kunde uppstå. Den inkvisitoriska processen var karaktäristisk för häxprocesserna. I motsats till den ackusatoriska processen kunde domaren ta initiativ till rättsliga processer och låta makthavarnas ideoloThe witchcraft trials in Europe took place from the 15th to the 18th century. The purpose of this presentation is to clarify the model of the legal process against the witches and give an explanation of how the witch hunts started. The inquisitorial process was characteristic for the witchcraft trials. As opposed to the accusatory process, the judge could initiate the process and let the ideologie

VDC is well developed within the construction of building and research and resources in the field have been spent under a longer period of time unlike in road and infrastruc
Problemställning: Till följd av Bergendahls Foods tillväxt de senaste åren har företagets transportplanering blivit allt mer komplex. Planeringen sker i dagsläget manuellt vilket gör att slutresultatet kommer allt längre från det optimala. För att anpassa planering och transporter till den ökande efterfrågan krävs en grundlig genomsyn av transporterna. Studien ämnar därför göra en kartläggning ochProblem: The manual transportation planning at Bergendahls Food has recent years become increasingly complex due to the growth in demand. In order to adjust to the changes, Bergendahls Food requires a thorough mapping of their transportation activities. The lack of supporting IT-system obstructs the ongoing transport review why this case study aims to map and analyze the transports in order to inv
Det har länge diskuterats om klimatförändringen som ett symptom på förhöjda utsläpp av växthusgaser orsakar några effekter. Ett resultat av årtionden av ökade växthusgasutsläpp är nu att effekterna av klimatförändringen kraftigt visar sig. Varmare väder, oregelbundet regn och kraftigare stormar är bara några exempel på effekterna som utsläpp av växthusgaser orsakar. När en individ får sin fastigheClimate change has been an issue for a long time. However, it is only in recent years that the effects have been highlighted, resulting in a discussion about climate change liability. Warmer weather, irregular rain patterns and more extreme weather are just some of the effects of climate change. What does an individual do when their property is swept away by a sudden flash surge? Naturally, they w
The aim of this study was to examine attitudes surrounding the needle exchange program in Malmö and Lund in Sweden. More specifically the aim was to examine how the staff of the needle exchange program experience the attitudes surrounding the needle exchange program and if/how these attitudes affect them in their work. The analysis of nine interviews with staff members revealed similarities in how
