Animals monitor environmental ques by translating them into electrical signals through a depolarization of the electric potential over the cell membrane of nerve cells. A way to initiate the depolarization is through activation of receptors that are ion channels. These channels can facilitate the diffusion ions across membranes driven by the differences in concentration and electrical charge on ea
In this paper, the viability of integrating solar power with an already running wind power plant is examined. The study, conducted in cooperation with Eolus, takes place in Anneberg, Sweden, home to three wind turbines with a combined capacity of 10.8 MW. This study examines whether or not it would be profitable to integrate an additional intermittent power source to the wind power plant’s existin
Recruitment of new individuals is essential for a population to survive and flourish and bladderwrack (Fucus vesiculosus) is on the decline in some parts of the Baltic Sea. The causes being multitude and complex, culminating to the loss of light penetration being the main culprit. As society moves forward, artificial submerged structures may serve as new footholds for a waning population as well a
The sperm whale (Physeter macrocephalus) is a cosmopolitan species with a broad distribution that ranges from the tropics to the poles. Males are known to migrate between nutrient-rich high latitude waters and low latitude breeding grounds. In the North Atlantic, large males are found up to the southern limits of the ice edge. However, their seasonal distribution patterns remain poorly known in th
When installing new research equipment at the synchrotron research laboratory MAX IV, a final positional accuracy of tens of microns is usually needed. To obtain that accuracy, initial reference points must be placed within 2 mm from the nominal target points in CAD, in a process referred to as bluelining. It is currently a manual process where points from a virtual environment are transferred to
Abstract in UndeterminedThe aim of this study was to evaluate the extent to which water use efficiency (WUE) at leaf scale can be used to assess WUE at canopy scale, leaf WUE being assumed to be a constant function of vapor pressure deficit and to thus not be dependent upon other environmental factors or varying leaf properties. Leaf WUE and its variability and dependencies were assessed using lea
The remodeling phase of tissue repair in lung disorders such as idiopathic pulmonary disease, asthma, obliterative bronchiolitis, and after lung transplantation is not well understood. One of the key players in fibrosis is the fibroblast and its progenitor, the fibrocyte. The fibroblast is the main producer of extracellular matrix molecules such as collagen, versican, perlecan, biglycan, and decor
The natural reservoir of influenza A virus is waterfowl, particularly dabbling ducks (genus Anas). Although it has long been assumed that waterfowl are asymptomatic carriers of the virus, a recent study found that low-pathogenic avian influenza (LPAI) infection in Bewick's swans (Cygnus columbianus bewickii) negatively affected stopover time, body mass and feeding behaviour. In the present study,
Introduction: In contact zones, genetic mixing of two taxa can be restricted by prezygotic (e.g. assortative mating) or postzygotic (lower fitness of hybrid offspring) barriers, or a combination of the two. A hybrid zone between two willow warbler subspecies (Phylloscopus trochilus trochilus, P. t. acredula) with distinctive migratory strategies occurs in central Sweden. These subspecies exhibit d
This dissertation discusses aspects of the syntax of Övdalian, a variety spoken by ca. 2,500 people in the province of Dalecarlia in Sweden. Initially, an overview of the history and current status of the language of Älvdalen is given, and the focus of the dissertation is on certain syntactic phenomena that have been well studied from a comparative and diachronic perspective in other Scandinavian
The two major aims of this study are (1) To test the performance of the Landscape Reconstruction Algorithm (LRA) to quantify past landscape changes using historical maps and related written sources, and (2) to use the LRA and map reconstructions for a better understanding of the origin of landscape diversity and the recent loss of species diversity. Southern Sweden, hemiboreal vegetation zone. The
Streptococcus pneumoniae (the pneumococcus) is a common colonizer of the human nasopharynx. Despite a low rate of invasive disease, the high prevalence of colonization results in millions of infections and over one million deaths per year, mostly in individuals under the age of 5 and the elderly. Colonizing pneumococci form well-organized biofilm communities in the nasopharyngeal environment, but
With the global population projected to reach eight billion by 2022, the world faces significant challenges associated with rapid urbanization. The migration of individuals from rural to urban areas in search of improved opportunities exacerbates the strain on resources, posing obstacles such as housing shortages, infrastructure demands, and food scarcity in growing cities. This thesis aims to add
With growing awareness about their environmental impact, music festivals have increased their efforts to become greener since the 2000s. In line with this trend, the German Fuchsbau Festival developed a transport plan, taking into account that up to 80.0% of a festival’s emissions are produced through audience travel. Aiming at triggering a greener travel behaviour among its visitors, four measure
Endowed with diverse vegetation covers, the Middle Atlas Mountains receive substantial snowfall in winter, which contributes to plant hydration during the growing season. Using remotely-sensed imagery, this study aims to assess the trends in snow cover variations between 2000 and 2015, analyse the local influence of snowpack persistence on vegetation growth and evaluate the significance of this ef
År 2006 var året då fler människor bodde i städer än på landsbygden och år 2030 uppskattas 5 miljarder människor bo i en urban miljö. Att lösa boendesituationen för de som flyttar till städer är ett globalt problem som kommer bli viktigare än någonsin tidigare att lösa. (Montgomery, 2014) Bostadsbyggandet i Sverige har de senaste åren ökat, men befolkningen ökar i ännu högre takt vilket gör att bo2006 was the year when more people lived in cities than in rural areas and by 2030 approximately 5 billion people will be living in an urban environment. Solving the housing situation of those who move to cities is a global problem that will become more important than ever to solve. (Montgomery, 2014) Housing construction in Sweden has increased in recent years, but the population is increasing at
Title: Bothness Despite Otherness: A Synergistic Approach in a NorthSouth Social Enterprise fusing Mutual Collaboration with Degrowth Values Authors: Ricarda Becker and Ladina Kaupp Supervisor: John Murray, Lund University, Sweden Purpose: This thesis aims to identify how mutual collaboration practices are infused with degrowth values within a business context that spans the Global North and the
