The eye as a window to the brain in heart failure. When the heart is injured such as after a heart attack, it may not be able to pump enough blood to meet the needs of the body. This is especially dangerous for organs like the brain that need a lot of oxygen and nutrients to function. The lack of normal blood supply leaves patients more likely to develop progressive cognitive impairment (CI) and
Plastic production is increasing every year and with it the amount of plastic debris found in the aquatic environment. These debris can be of different sizes including micro- and nano-sized particles. The latter have been found to be more toxic than bigger particles, in special particles smaller than 53 nm of diameter. This is because their small size allows them to pass biological barriers like t
Pollenidentifikation med artificiell intelligens Artificiell intelligens är inte längre sci-fi, utan finns omkring oss i vår vardag och snart kanske även som kollegor i labb och på andra arbetsplatser. En form av artificiell intelligens som kallas convolutional neural network (CNN), känner igen strukturer i bilder och kan därför användas t.ex. för identifiering av pollenkorn, vilka traditionellt
Tvekande hjortdjur Vägar utgör ett hinder och stor fara för många djur. Ljus och ljud stör djuren och vid stora mängder trafik blir vägen en barriär. Broar och tunnlar kan ge dem möjligheter att passera förbi, men ytterligare kunskap behövs för att veta hur man ska utforma dessa. Tidigare har man mätt antalet av besökande djur som passerat igenom för att bedöma hur väl broarna fungerar. ResultateWildlife crossing structures are needed to enable animal movements in an all more broken up landscape. The Swedish Transport Administration need to know how to build these. Previous studies have focused on passing frequencies and indices. Few have looked at the behavior of the visiting animals. In this study, I have complemented passage frequencies with vigilance behavior for roe deer and fallow d
Solving finite-sum minimization problems could be done by the use of a gradient descent algorithm. The algorithm evaluates the gradient with respect to the current state of the parameters and updates the parameters in the direction of the steepest descent. For certain problems, evaluating the full gradient at every iteration is computationally heavy and the gradient of the objective function is th
Denna studie undersöker hur tre klassiska sångpedagoger på avancerad nivå ser på tungans funktion och hur de diagnostiserar, analyserar och arbetar med oönskade tungspänningar. Ett övergripande syfte är även att undersöka om det går att urskilja ett mönster i sångpedagogernas syn på arbetet med tungan och tungspänningar. Studien är kvalitativ och utförd med semistrukturerade intervjuer. För att ävThis study explores three classical voice teachers’ views on the function of the tongue in singing and how they diagnose, analyze and work with unwanted tongue tensions. My focus is to determine whether it is possible to find common denominators in the voice teachers’ conceptions of the tongue and unwanted behavior of the tongue. I use a qualitative approach in my study, where data is collected th
Det finns många olika utformningar av lyfthjälpmedel och hjälpmedel för att gå, så som patient lyftar och rullatorer, men det finns inte många lösningar som kan göra båda. Detta examensarbete är baserat på en person med fysisk funktionsnedsättning som har specifika behov för vilka det inte fanns någon anpassad lösning. Målet var att utveckla en produkt som kan lyfta användaren från sittandes till There exist many different designs of lifting aids and walking aids, but barely any solutions that can do both. This thesis is based on a person with mobility impairment with specific needs for which there were yet no adapted solution. The goal was to design a product that can lift the user from sitting to standing position and then be a walking aid by supporting the user by the armpits, all this
Ekonomiska sanktioner har blivit ett populärt påtryckningsmedel för att försöka få stater att ändra sin politik och sitt beteende. Efter det kalla kriget ökade antalet sanktioner kraftigt. En stor del av sanktionerna var fokuserade på länder där man ville åstadkomma demokratiutveckling. I min studie har jag undersökt vilken påverkan demokratisanktioner från EU, USA och FN under perioden 1990-2
The student group is an emerging target with high potential for both the service industry and municipalities. However, previous studies scrutinizing this segment have been limited despite its significance. The aim of this study is to provide a deeper understanding of how domestic and international students perceive Helsingborg city and to offer insight into the key factors influencing students’ pe
Detta arbete sammanställer den prekambriska berggrunden och dess geologiska utvecklingshistoria i nordvästra Skåne. Studien baseras främst på SGUs berggrundskartor som benämns Af. 148 Helsingborg NO och Af. 180 Helsingborg SO samt tillhörande berggrundsbeskrivningar. Berggrunden inom det studerade området har bildats under regionala geologiska processer och dessa beskrivs it ett bredare perspektivThis study aims to summarize the Precambrian bedrock and its’ geological development in north-western Skåne. The study is primarily based on two SGU bedrock maps called Af. 148 Helsingborg NO and Af. 180 Helsingborg SO, plus the associated bedrock descriptions. The bedrock within the studied area developed during large regional geological processes and these are described in a larger perspective.
Labour markets in Europe are changing from permanent employment to more flexible structures. Atypical work such as temporary work become more prevalent. In Germany, there is a high share of temporary work contracts within social work. The aim of this study was to understand what temporary employment means for the employees and which effect it has on the lives of the employees. The chosen method fo
Utifrån vandringar och undersökningar skapas ett lokalt förankrat konstnärsresidens i vilket man som konstnär och besökare har goda möjligheter att bygga vidare på den karaktär som mittskåne erbjuder. Inspiration har hämtats från lokala författare och diktare men också från bygden i sig. Frostavallen, vilket valet av site föll på, har ett rikt förflutet och en unik historia. Genom det här projekteBased on hikes and research an artist residency is created where one as a visitor or artist have a good prospect of creating something within the unique character of mittskåne. Inspiration has been found in local authors and poets but also from the area itself. Frostavallen, which became the site of this project, has a rich and very interesting past. Through this project I hope to revitalise the a
Att näringsidkare behandlar enskilda individers personuppgifter till ändamål för att individanpassa marknadsföring genom elektronisk väg får anses vara vanligt i dagens digitaliserade samhälle. Personuppgifter har fått ett eget kommersiellt värde och kan ses som en tillgång som bland annat genererar intäkter och konkurrensfördelar. Det är dock viktigt att individer får det skydd som krävs för att Personal data has an inherent commercial value and can be seen as an asset that generates revenue and competitive advantages. It is important that individuals receive the necessary protection for their personal data so that it is not used or processed in ways that are not legally compatible. The General Data Protection Regulation (GDPR) creates protection for individuals by informing organizations
This paper assesses the effectiveness of foreign aid in reducing poverty and increasing HDI by analysing three different types of aid; bilateral, multilateral and NGO aid. While there have been several papers that have studied the differences between bilateral and multilateral aid and their effectiveness, such studies have not included NGO aid. In addition, research on what impact foreign aid has
Ecological rehabilitation projects - as a form of reforestation interventions - are increasing worldwide and present an opportunity for climate change mitigation and supporting local livelihoods. Implemented in post-conflict situations, they are increasingly promoted as solutions for peace. Aiming at understanding their contributions to sustainability and peacebuilding, I examine proposed rehabili
Shale gas extraction commonly known as fracking had support from the UK government with their ‘all out for shale’ policy. Despite this industry has struggled to establish itself mainly due to strong opposition from communities concerned about environmental and health impacts. Most research into the impacts of fracking is concerned with either environmental degradation or physical health impacts wh
Amidst global warming, perturbed ecosystems and an ever-diminishing fossil feedstock, a paradigm shift toward renewable and sustainable plastics have emerged. Significant advances have been made in the past decade and several green polymers have entered the market. Much attention has been focused on the catalytic conversion of lignin, as it represents the largest source of renewable platform chemi
Ecological compensation builds on the idea of substitutability, meaning that destroyed values can be replaced or substituted with new values that are equal to the ones lost. Through this equivalence between “lost” and “gained” values compensation is meant to allow dynamic economic development without causing irreversible biodiversity loss. Compensation is increasingly used as a means to reduce the
Can constructed wetlands be used to fight cyanobacterial blooms? Cyanobacterial blooms are more than just a nuisance that prevents swimmers from making the most of the warmest months. Cyanobacterial blooms can cause a wide array of problems such as polluting freshwater reservoirs and causing fish die offs, owing to their ability to grow rapidly and release toxins which are harmful to both humans
