We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. Identifying the ways higher temperatures affect tundra carbon cycling, one of them being the decline of sea ice, can

Syftet med detta arbete har varit att undersöka faktorer som påverkar kombinationen av fastigheter inom detaljplanerat område som är taxerade för både bostadsändamål och industriändamål. Detta har gjorts genom litteraturstudier av relevanta lagar, och förordningar, en kvantitativ undersökning av fastigheter som är taxerade för ändamålen, en intervju med fastighetsvärderare samt en analys. Under pThe purpose of this work has been to investigate properties in Skåne County, Sweden, with detailed development plans with provision that approve both industrial and residential purposes. The majority of the properties had a detailed plan that gained legal force between 1950 and 1987. During the period, industrial and residential purposes were a recommended use in the planning instructions. With t

Theoretical perspective: Venkatesh, Thong and Xu’s (2012) Extended Unified Theory of Acc

Hemoglobin från växtriket: en lösning på blod- och järnbrist i samhället? Många känner till hemoglobin som det protein som ger vårt blod dess röda färg och som håller oss vid liv genom att transportera syre till våra celler. Mindre känt är att nästintill alla organismer har gener i sitt DNA som kodar för liknande proteiner, även om de inte tar formen av blod så som vi är vana vid. I det här projHemoglobin is a protein transporting oxygen through our bloodstreams and is as such essential for aerobic life. Hemoglobins also exist in plants, with a wide variety of functions other than oxygen transport. The study of plant hemoglobins could potentially be interesting for the development of synthetic blood substitutes and have also shown promise as an alternative dietary source of the more bioa

Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. In a clinical setting, usually around 10 mL of blood can be col

Eutrophication caused by nutrients such as phosphorus has become a major issue over the years. Dealing with this phenomenon is a major concern in many countries, and municipalities are establishing strict rules to cope with this problem in water bodies. However, the development of cities has a cost, and supplying the food needs of people is essential. In order to optimize agricultural lands, the u

Artificiella Neurala Nätverk (ANN) är en form av maskininlärning som är populär just nu. Den har många användningsområden inom dagens teknik, till exempel som bildigenkänning. Att programmera ett sådant nätverk är dock inte det lättaste man kan göra. Ett vanligt problem som uppstår när ett ANN byggs upp är överträning, vilket sker när nätverket är för kraftfullt för problemet det ska lösa. En vanlL2 regularization is a common method used to prevent overtraining in artificial neural networks. However, an issue with this method is that the regularization strength has to be properly adjusted for it to work as intended. This value is usually found by trial and error which can take some time, especially for larger networks. This process could be alleviated if there was a mathematical relationsh

Kartlägga buskar på Öland för att rädda den biologiska mångfalden. På södra delen av Öland finns ett område som kallas Stora Alvaret som har mycket höga naturvärden. En minskning av betande djur under 1900-talet har dock gjort att den biologiska mångfalden hotas av buskar som sprider sig och utkonkurrerar andra växter. I examensarbetet Looking for shrubs in an alvar undersöker Jorun Westman metodeLoss of biodiversity is an immediate threat to the planet and if no actions are taken it is expected to accelerate. The highest species richness on smaller scale is found in semi-natural temperate grasslands, with one of the documented records from Stora Alvaret on Öland, Sweden. The area is protected under the Natura 2000-network and Länstyrelsen Kalmar are responsible for monitoring while local

Abstract Background: As the population ageing increases, the dramatic rise in cognitive disorders such as mild cognitive impairment and dementia has become a public health priority. Mobile health technology is a unique non-pharmacological intervention for dementia and cognitive disorders. A digital platform (Support Monitoring and Reminder for Mild Dementia: SMART4MD) is created for persons with m

En stor del av samhällets miljöpåverkan kommer från bygg- och fastighetssektorn. Från årsskiftet 2022 finns det nya krav för nybyggnationer på att en klimatdeklaration ska genomföras för bärande konstruktionsdelar, innerväggar samt klimatskärmar. Kraven kan vara ett startskott för att fler delar i byggnader ska klimatdeklareras. Projekt Villazero, ett småhus som uppförs i Borlänge av Fiskarhedenvi

In China, after implementing the family planning policy in 1979, a huge group of women with unapproved birth were formed. However, the academic research on them are very limited. For women with unapproved birth, sacrificed the most under this “magical” that eliminated hundreds of millions of people in China, but their reproductive practices and experiences are being neglected and ignored.

Ett vanligt förekommenade problem vid utformning av stål-och betonganslutningar i hörn är att platsbrist kan ge upphov till anslutningar som är asymmetriskt utformade. De avvikande placeringarna på bultarna medför komplexa beräkningar och skapar ett behov av förenklade modeller vid design. Förenklingen kan leda till skillnader i brottsbeteende mellan designen och den fysiska produkten vilket kan lA commonly occurring problem when designing steel-to-concrete connections in corners with space deficits is the necessity for irregularly placed bolts with regards to design codes. The complexity of the calculations for the irregular placements of bolts generates the need to use simplified models during the design. This simplification could lead to differences between the design and the physical p

Icons are widely used throughout society; moreover, they play a significant role in computer user interfaces, frequently appearing on websites and applications. In many cases, they are used instead of text labels to make a user interface (UI) more universally understood, among other things. Since icons reside within the UI, they should adhere to UI design principles, such as ”reduce short-term mem

To the texture of the food we eat to the process design and the choice of process equipment. The project focuses on understanding viscosity related data and its importance in calculating process design rela

Beräkningar med stora matriser är svåra och långsamma att utföra, även för datorer. Med hjälp av en matrisens egenvärden kan man istället arbeta med dess karaktäristiska polynom, där egenvärdena är nollställen. För mycket stora matriser får detta polynom en hög grad och vi skulle vilja approximera det med ett av lägre grad för att förenkla beräkningarna ytterligare. En populär metod för att göra dThe Remez algorithm is a beautiful algorithm that finds the best approximation to a function by finding points satisfying the alternation condition. In 1987 Ping Tang published his doctoral thesis detailing a version of the Remez algorithm modified for functions of complex values with complex coefficients. He later followed the thesis with an article presenting an algorithm for finding the coeffic

In doing so a practical new dashboard layout shall be reached, which considers the needs of all dashboard users. Design/methodology/approach – This thesis was co

Gold is known in the financial world to be an important asset in unstable periods, especially as a hedge against inflation. If the gold price can be forecasted, it will be possible to strategically invest in gold rather than acquire it as a last-minute hedge against economic downturns. Although there are many studies on forecasting, few focus directly on gold returns. This study investigates the

Hostile architecture is a tool used to control and regulate behavior, individuals, and groups in public spaces. This research explores the use, purpose, and meaning of hostile architecture in Copenhagen. To explore the phenomenon, I conducted fieldwork and semi-structured interviews. The fieldwork consisted of sensory ethnography within a phenomenological framework of data collection and analysis.
