The phenomenon of overtourism encapsulates the spirit of contemporary mass tourism. It has gained attention lately as an unsustainable consequence of the intensification of destination management principles in urban economic planning strategy. Stories about “the invasion” of visitors into a numberof popular European cities frequently circulate in news and social media. Research has begun to examin

Alzheimer’s disease is an aging related disorder of the mind, accountable for 60-80 percent of all cases of dementia. With its insidious progression and the decline of cognitive abilities, this disease is a major challenge for our society as a whole. This is because of the growing proportion of people living to advanced age and our current lack of capacity to prevent or even give effective symptom

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

Purpose: The purpose of this study is to explore how brand managers align their brand identity within online brand communities where the communication is shared in order to create a reinforcing point of contact instead of a source of mixed messages. Problem: With the increasing usage of the internet, brand managers are today forced and challenged to align and re-enforce a brand’s identity online w

Background The 2002 EU directive on the energy performance of buildings stipulates that buildings must be energy certified. In order to implement the directive in Sweden it is proposed that a law on the energy certification of buildings be introduced on 1 January 2006. The law shall apply to all buildings where energy is used to condition the indoor climate. However, there are a number of exceptio

Accessibility is something often taken for granted in our society, but it is a necessity for people with disabilities. Railway stations are a public place and are often a connecting point for several modes of transport. Design of railway stations in terms of accessibility for persons with disabilities is governed by several national and international governing documents. The purpose of this thesis

Läckage och spill från cisterner utgör de vanligaste orsakerna till förorening av grundvatten med petroleumprodukter. Bensin och dieselföroreningar sprids inte enbart längs grundvattenytan utan lösta beståndsdelar kan transporteras med grundvattnet relativt långa sträckor. Flyktiga kolväten förflyttar sig i den vattenmättade zonen beroende på föroreningens utbredning och fördelning. Flera tusen aSpills and leaks from storage tanks constitute the most common groundwater contamination source with petroleum products. Gasoline and diesel pools do not spread extensively along the water table, but dissolved constituents are transported in groundwater on relatively larger distances. Volatile hydrocarbons migrate in the vadose zone dependently on distribution and extent of the dissolved and pure

Detta arbete har som syfte att besvara två frågeställningar - hur ser lagstiftningen ut för miljökonsekvensbeskrivningar för planer och program i Sverige, och vilka krav kan ställas utifrån denna, samt hur dessa krav har uppfattats i genomförda miljökonsekvensbeskrivningar för planer och program? Detta görs genom en genomgång av lagtext, förarbeten, praxis och litteratur på området, en granskning This work aims to answer two questions - how does the legislation for environmental impact assessments for plans and programs in Sweden look like, and what demands can be made from this, and how are these requirements perceived in conducted environmental impact assessments for plans and programs? This is done through a review of the statutory text, legislative history, case law and literature, an

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

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

Wind power developments in cold and icing conditions pose new challenges to the wind power industry. Icing of wind turbines cause safety hazards, production losses and increased loads. This means that there is a need to develop a technique to quantify the icing climatology and corresponding eects on wind turbines to enable large scale wind power developments in the windy, sparesly populated areas

Several beneficial effects have been connected with dietary fibre. Insoluble fibre has a good faecal bulking capacity, whereas soluble and viscous dietary fibre has been shown to have beneficial effects on carbohydrate and lipid metabolism. Fruit and vegetables provide about one third of the dietary fibre intake in Northern Europe and more than half in Mediterranean countries. These food items are

Popular Abstract in English Lions (Panthera leo) have become known to be synonymous with wild Africa since its extinction from most parts of its former range (Europe, Asia and Southern America). Few people realize that anthropogenic activities have caused habitat loss, fragmentation and reduction in size to the lions, forcing them to the brink of extinction. Whenever out in nature, most tourists tHigh growth rate in human populations, agricultural developments and industrialization have impinged negatively on the natural habitats of most large carnivores, causing fragmentation, isolation and consequently reduction in population size. Lions (Panthera leo) that once roamed most parts of Southern Europe, Asia, the Middle East, North America, northern part of South America and most parts of Af

Radar data at C-band has shown great potential for the monitoring of soil and canopy hydric conditions of wheat crops. In this study, the C-band Sentinel-1 time series including the backscattering coefficients σ0 at VV and VH polarization, the polarization ratio (PR) and the interferometric coherence ρ are first analyzed with the support of experimental data gathered on three plots of irrigated wi

Background: Speech impairments are an early feature of Alzheimer’s disease (AD) and consequently, analysing speech performance is a promising new digital biomarker for AD screening. Future clinical AD trials on disease modifying drugs will require a shift to very early identification of individuals at risk of dementia. Hence, digital markers of language and speech may offer a method for screening

Moving from a fossil dependent to a fossil free economy requires increased energy production from renewable resources. This thesis discusses the utilization of agricultural waste streams, such as straw and manure, for biogas production. The first part of the research presented focuses on pretreatment of straw with the aim to reduce the handling issues concerning straw and improve the degradation o

The 2015 Paris Agreement of the United Nations Framework Convention on Climate Change aims to keep global average temperature increases well below 2 °C of preindustrial levels in the Year 2100. Vital to its success is achieving a decrease in the abundance of atmospheric methane (CH4), the second most important anthropogenic greenhouse gas. If this reduction is to be achieved, individual nations mu
