This thesis explores the state-of-the-art methods for the optimization of Wireless Power Transfer (WPT) for Radio Frequency (RF) energy harvesting with a view of increasing the efficiency of the Radio Frequency to Direct Current (RF-to-DC) conversion, which is a key parameter in the creation of Zero Energy Devices (ZEDs) in the context of Internet of Things (IoT). The research focuses on waveform
Safe and clean drinking water delivery is challenged by climate change, as elevated temperatures can promote the growth of pathogens and other detrimental microorganisms. The microbial processes underlying drinking water production in slow sand filters (SSFs) are largely uncharacterized, limiting the possibilities of improving this technology. Periodical clogging, potentially by microbes, disrupts
The dynamics of China’s complex policy process, shaped by the decentralization reforms of the 1980s, remain the subject of much discussion. As China spent three years adhering to its eradication strategy in response to the COVID-19 pandemic, it seems that the relevant theories from the past need to be updated. The purpose of this study was to understand how irrational decisions were made and why u
In this written study, I have researched video game music from the 90’s and early 2000’s to see what I can learn from the process of composing music for video games, as well as how the hardware and software capabilities of the game consoles shaped the music. First it presents my own background and relation to the subject, next it establishes what functionally separates video game music from conven
Intersections have long been recognized as high-risk areas for traffic accidents, with vehicle collisions in Non-Line-of-Sight (NLoS) scenarios resulting in significant economic and human losses. This thesis investigates a vehicle collision avoidance system that integrates Machine Learning (ML), wireless communication technologies, and sensor fusion with Global Navigation Satellite System (GNSS) p
The invaders vs. the protectors: who wins the battle? Pseudomonas aeruginosa or in short PsA is a type of microorganism, also known as “bacteria” or “germ” or “bug”. It is very tiny and invisible to our naked eyes. This germ is found everywhere in places like soil, and water. PsA can get into the human body through wounds and other injuries and make people sick. To prevent humans from getting inf
Utforskandet av nya roller av komplement proteinet C3 Komplementsystemet är en uråldrig evolutionär mekanism i det medfödda immunförsvaret och funkar som en av kroppens första försvarslinje. I detta gamla system finns det ett protein som sticker lite mer, ett protein som har en central roll i komplementsystemet, nämligen komplement protein C3. Inte nog med att den har en viktig roll i framkallninThe complement system is an ancient component of the immune system, comprising three pathways: classical, lectin and alternative pathways. Central to these pathways is complement component C3, which converges the three pathways. C3 can be enzymatically cleaved into C3a which functions as an anaphylatoxin, and C3b, which functions as an opsonin. Previously, C3 was understood as a serum protein, how
Abstrakt Bakgrund: Personalbrist i primärvården har lett till svårigheter att tillgodose patienters vårdbehov. Distriktssköterskor har i tidigare studier beskrivit att deras kompetens och arbetsområde inte prioriterats av chefer och övrig primärvårdspersonal. Konsekvens till följd av detta ledde till att deras hälsofrämjande och sjukdomsförebyggande arbete inte hanns med trots att ett av primärvå
With the persistent phenomenon of rapid urbanization, cities worldwide are in a constant state of change. This transformation extends to the underlying "urban fabric" that encompasses the distinct segments that collectively shape the identity and character of a city. These segments can be formally categorized as districts, boroughs, neighborhoods, or wards. However, at a deeper level fam
Today aromatic ring flipping has become a classic example to highlight the highly dynamic character of proteins. These dynamics occur when the aromatic side chains in phenylalanine and tyrosine turn 180o around its Cβ–Cγ axis, also known as its χ2 dihedral. Discovered in the 1970s’ these ring flippings are a common internal probe used in NMR spectroscopy to understand the protein interior dynamics
Bakgrund: Distriktssköterskans förskrivningsrätt inom primärvården bidrar till effektivisering och förbättring av vårdtillgängligheten inom hälso- och sjukvården. Trots potentiella fördelar finns det distriktssköterskor som inte alltid använder förskrivningsrätten. För att optimera användningen av förskrivningsrätten behövs ökad kunskap om distriktssköterskors erfarenhet i rollen som förskrivare.
Bakgrund: Sverige har upplevt en demografisk förändring där 20% av befolkningen har utländsk bakgrund vilket skapar nya krav på hälso- och sjukvården. Hudbedömning är särskilt utmanande eftersom variationer i hudfärg påverkar diagnos och behandling. För att undvika felbedömningar och upprätthålla en god vårdkvalitet behöver vårdpersonal, inklusive distriktssköterskor, kunskap om melaninrik hud. SBackground: Sweden has experienced a demographic shift, with 20% of the population now having a foreign background, which creates new demands on the healthcare system. Skin assessment is particularly challenging as variations in skin color impact diagnosis and treatment. To avoid misdiagnoses and maintain high-quality care, healthcare professionals, including district nurses, need knowledge about
Previous research has shown that conducting scientific research aimed at studying human behavior in a virtual environment in the context of safety is feasible. However, most applications of this kind are done with a primary focus on the visual aspects of the virtual environment. This study investigates if (a) a visual and auditory recreation of a real-world environment in Virtual Reality (VR) for
Purpose: This paper aims to explore the concept of brand purpose and examine how corporate brands across different industries (B2C versus B2B) communicate and integrate it into their marketing and operational strategies. Design/Methodology: The research was conducted using a qualitative approach through three semi-structured interviews with marketing professionals with experience from four compani
Bakgrund: Den globala befolkningen åldras, och enligt WHO kommer 1 av 6 människor att vara 60 år eller äldre år 2030. I Sverige är en fjärdedel av befolkningen redan 60 år eller äldre, vilket har ökat omvårdnadsbehovet i hemmet. Patienter skrivs ut snabbare från sjukhus, vilket ställer högre krav på kommunal hälso- och sjukvård. Distriktssköterskor har en viktig roll i att leda och samordna omvård
Bakgrund: Sveriges regering har ökat kraven på tillgänglighet inom primärvården, som avser att se till att patienten kan nå fram till vården, men även få den vård denne är i behov av inom en rimlig tid. Distriktssköterskan kan ställas inför en utmaning för att möta patienternas efterfrågan och vårdbehov. Syfte: Syftet var att belysa distriktssköterskans erfarenheter av att möta och hantera kraven
