The mycelium enables a fungus to explore and interact with spatially and temporally heterogenous environments. It operates at a range of scales, with hyphal traits and cellular events affecting network and colony behavior. Recently, the fungal mycelium has also been used to produce new, sustainable biomaterials which can serve as alternatives to numerous non-renewable or polluting materials and pr
This thesis proposes a fully integrated transformer-coupled active power and antenna impedance detector for WLAN 802.11ax 5 and 6 GHz frequency bands. The detector is integrated into a transceiver, utilising the receive chain to down convert sensed RF voltage and current and digitally calculate the active power and antenna impedance on-chip. The RF current measurement is realized by a sense windin
Humanitarian Crisis is an alarming problem throughout the world. Bangladesh also is undergoing Rohingya refugee crisis with grave severity and challenges. Over 1 million Rohingya people have been settled over the top of hills, living without inadequate WASH facilities. This study tried to analyse the humanitarian crisis by Pressures-States-Responses framework depicting the factors exacerbating the
The literary heroic ideal changed with the Great War, as the Victorian hero ideal was no longer plausible in a post-war world. The new ideal was pacifist and non-heroic but not everyone who had been through the Great War agreed that there was no heroicism. This essay discusses the development of the heroic ideal in the mid twentieth century in relation to the two brothers Boromir and Faramir in J.
As artificial intelligence (AI) becomes increasingly embedded in organisational operations, it introduces not only efficiency but also unique information security challenges. Traditional security practices cover common threats, however, the lack of transparency in AI output and the possibility of novel attacks such as data poisoning and phishing attacks show that these systems are poorly equipped
This work explores the catalytic activity of decavanadate (V10)-based catalysts in the selective oxidation of ethylbenzene (EB), a model compound of lignin-derived molecules, under mild conditions. The goal is to assess the catalytic efficiency, product selectivity, and the influence of counter-ions on activity through systematic testing of parameters such as temperature and catalyst loading. Addi
Moderate exercise is deemed beneficial for cognition due to increase in dopamine concentrations in the basal ganglia. Auditory white noise is beneficial for cognition, mainly for those with lower attentional ability, i.e. for those having lower tonic dopamine concentrations. For individuals with higher attention ability white noise can have a negative effect. In this thesis it was examined whether
All vårdpersonal bör ges grundläggande kunskaper om smärtsinnet, reaktioner på smärta samt behandling av olika typer av smärta. Sjuksköterskor ska dessutom ha god kännedom om tekniker för smärtskattning, om psykologiska faktorers betydelse och om traditionella smärtstillande läkemedels kliniska användning (SoS-rapport 1994:4). Syftet med denna studie var att undersöka förekomst, innehåll och mål f
Bristande handhygien inom vården är ett globalt problem och det finns ett samband mellan låg följsamhet av rutiner för handhygien och förekomsten av vårdrelaterade infektioner. Syftet med denna studie var att undersöka sjuksköterskors syn på orsaker till bristande handhygien samt vilka möjligheter som finns för förbättringar. För att undersöka detta användes ett frågeformulär med öppna frågor som
This thesis covers the design of a wideband, flexible front end for LTE and LTE-A in a 65 nm CMOS process. A topology with global frequency translational feedback is investigated and a harmonic rejection mixer is implemented. To compensate for parasitics at the RF input, a variable phase shift is used in the global feedback to improve input matching and prevent loss of noise performance. Combinati
Besvär från rörelseorganen, framför allt från rygg och nacke är en av de vanligaste anledningarna till sjukfrånvaro i västvärlden. Patienter med dessa besvär utgör en stor andel av de som söker primärvården där fysioterapi ofta är första linjens vård. Rygg och nacksmärta kan orsaka nedsatt funktion och aktivitetsförmåga vilket ofta innebär en betydande förlust av livskvaliteten samt ekonomiska konPatients with back and neck pain are frequently seen in primary care, where they are directed to physiotherapy as first-line treatment. The condition affects both the individual, by causing pain and disability, and society, because of high costs caused by work disability and health care consumption. Clinicians need tools to identify, at an early stage, patients at risk of poor outcome, in order to
BACKGROUND: The recent discovery and specific functions of D-amino acids in humans are bound to lead to the revelation of D-amino acid abnormalities in human disorders. Therefore, high-throughput analysis techniques are warranted to determine D-amino acids in biological fluids in a routine laboratory setting. METHODS: We developed 2 chromatographic techniques, a nonchiral derivatization with chira
This research investigated the liquid-phase removal of chloramphenicol (CAP), an emerging contaminant using molecularly imprinted polymers (MIPs). CAP adsorption profiles, equilibrium, and kinetics were analysed. The adsorption performance was compared between MIPs and non-imprinted polymers (NIPs), both with silica or without silica grafting. The imprinting factor (IF) values for the Si@MIPs-CAP
A green route for the production of 6-carbon polymer building blocks 6-hydroxyhexanoic acid, adipic acid and ϵ-caprolactone from 1,6-hexanediol, a hydrogenation product of biobased 5-hydroxymethylfurfural is reported. Gluconobacter oxydans oxidized 1,6-hexanediol completely to adipic acid, and selectively at pH 6-7 to 6-hydroxyhexanoic acid, which was converted to ϵ-caprolactone by catalytic cycli
In Ethiopia, full vaccination coverage among children aged 12–23 months has improved in recent decades. This study aimed to investigate drivers of the improvement in the vaccination coverage. The Oaxaca–Blinder decomposition technique was applied to identify the drivers using data from Ethiopian Demographic and Health Survey conducted in 2000 and 2016. The vaccination coverage rose from 14.3% in 2
Spectroscopic Photoemission and Low Energy Electron Microscopy (SPELEEM) is a very powerful and diverse microscopy technique for the investigation of surfaces, interfaces, buried layers and nanoscale objects like nanoparticles and nanowires. The many significant results from photoemission Electron microscopy (PEEM) in recent years are linked with the exploitation of advanced light sources such as
