Vad som avgör arters heterogena fördelning över landskapet är något som länge har fascinerat och intresserat biologer. Vad som påverkar biodiversiteten är däremot komplext, med en rad olika faktorer som inverkar tillsammans. För att studera biodiversiteten krävs någon form av mått och det vanligaste är att beräkna artrikedomen. I den här rapporten används data över artrikedomen av kärlväxter i Skå
The objective of this thesis is to better understand what factors produce an enabling environment for land grabs after a disaster. Looking at eight selected case studies, this research tests the role of land tenure security, private capital investment and global financial institutions, and gender. The factors are tested with a mixed methodology: proxy indicators are analyzed quantitatively, and ca
III-V semiconductor nanowires (NWs) display outstanding potential for many technological applications, but their implementation into devices is restricted due to high material and fabrication costs. Common techniques for NW synthesis rely on single crystalline substrates, which are single-use and have large costs associated to them. In this project a method for substrate reuse was designed and in
Ditt dricksvatten kan innehålla hälsofarligt kadmium från berggrunden Har du dricksvatten från egen brunn hemma? Eller har du sommarstuga på landet med egen brunn? Då bör du se till att regelbundet provta ditt vatten! Grundvatten är generellt renare än ytvatten, och i vissa fall är det så rent att det kan drickas utan föregående behandling. Men grundvatten kan också innehålla ämnen som är skadliCadmium poses a threat to both human health and the environment. In this study, cadmium levels in groundwater in the area around Rörums Fur in the municipality of Simrishamn, Sweden, and their potential sources were mapped, with the aim of getting an overview of the cadmium situation in the area. For this purpose, groundwater analysis data from various sources were compiled and compared to informa
Early-life health shocks can have very serious long-term consequences for those exposed to them, a fact which must be considered when parents make decisions with regards to allocating resources across their children. Here, the 1980 famine in Karamoja, Uganda is used as a natural experiment in which to test whether parental investment responses reinforce or compensate the impacts of early-life shoc
The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. In Sweden, the forest industry is an important part of the economy. The pulp mills pro-duce an excessive amou
Studien undersöker huruvida långsiktig underprestation förekommer för 1770 börsintroduktioner på NYSE och NASDAQ 5 år efter börsnotering mellan 2000-2014 och om nyemissioner gjorda av samma företag har en negativ påverkan på aktieutvecklingen. Av resultatet framgår att ingen allmän underprestation råder men att de bolag som genomfört en nyemission under mätperioden underpresterat med 6,65% mot S&a
Many insects are able to detect, isolate and track small targets that move quickly against a dynamic background. This ability is enabled by a group of neurons called small target motion detectors (STMD). These neurons, among other properties, have a type of short term memory called response facilitation. This type of facilitation is a phenomenon in which continued visual stimuli lead to an enhance
I samband med lantmäteriförrättningar där ersättningsbeloppet behöver framtas med hjälp av de värderingsmedel som Lantmäteriet eller utsedd värderingsman har att tillgå är det ytterst viktigt att ingångsparametrarna är korrekta. Då fastighetsregleringar där vinstfördelning blir aktuellt och där genomsnittsvärdeprincipen aktualiseras är det råtomtmarksvärdet som eftersöks. I värderingsutlåtandet reDuring land surveying operations, the amount of compensation needs to be calculated using the valuation means taken by the land surveyor or appointed appraiser. For this reason, it is important that input parameters are correct. As profit distribution is a pressing concern in relation to real estate regulations, raw land value is sought after. In this case, the responsible land surveyor reports fo
The main purpose of this study was to investigate if guanxi increases or decreases international management control mechanisms for foreign MNCs in China. The authors interviewed managers at three Scandinavian MNCs with subsidiaries in China for a comparative case study. Based on previous literature, guanxi was categorized into personal guanxi and organizational guanxi, as well as family guanxi, bu
One of my main interests as an architect has been to reflect upon the sense of place and memory, both from the context where I am and from my own personal experiences. As a university-city, Lund (Sweden) is one of the most important nodes of the Oresund Region. Here, tradition and innovation coexist, not only from the varied academic activities but also from how these dynamics have influenced the
Three-dimensional food printing is an emerging application within the realm of 3D printing with the potential of transforming the foods we consume. The technique harbors incredible potential for improving the eating experience of people suffering from dysphagia, an ailment which causes discomfort at the time of swallowing. Patients suffering from this condition have special diets consisting of tex
The transport of terrestrial carbon through riverine systems to coastal water may have a negative impact on the oxygen concentration. However, information on seasonal variation and the impact of composition of the catchment area on bioavailability is lacking. This paper covers the January and April samplings, which are a part of a yearlong study. To examine the seasonal variation in composition an
As form of effort to mitigate the increase of pollution level that caused by human activity, Ängen wastewater treatment plant (WWTP) will be built in Lidköping as part of the European LIFE project (LIWE LIFE). Ängen WWTP will be operated based on enhanced biological phosphorus removal (EBPR) technology. This treatment plant is projected to be cost effective and resource efficient, therefore this t
Enligt en undersökning gjord av industrifakta kan effektivare kommunikation leda till besparingar på över 30 miljarder årligen i byggbranschen. Ett sätt att effektivisera kommunikationen är att välja rätt kommunikationskanal vid rätt tillfälle. Syftet med detta examensarbetet har varit att bidra till effektivare kommunikation genom att ta fram en enkel metod för val av kommunikationskanal i byggp
Det sker stora klimatförändringar i världen. Den förstärkta växthuseffekten gör att medeltemperaturen stiger och för med sig allvarliga konsekvenser. För att hålla medeltemperaturhöjningen under 2 grader skrev flera länder under Parisavtalet 2015 för att försöka reducera utsläppen av växthusgaser. Sveriges långsiktiga mål är att 2045 inte ha några nettoutsläpp av växthusgaser. Byggsektorn står f
This thesis investigates if it is possible to measure the plunger position in a Ledex 282352-023 solenoid actuator without the use of external sensors. To do this, various different methods, all based on comparing the current response to the applied voltage were evaluated from different categories such as calculation time, reliability and distinct position levels. The method that performed best in
Digital healthcare has proven to be increasingly important as the pressure on primary healthcare is enhanced, with a growing elderly population that lives longer. The importance of an effective digital healthcare with high quality is consequently increasing. By creating a reliable model, using machine learning algorithms, that can predict the next action for a caregiver in digital healthcare, not
