The aim of this thesis is to design two patch antenna arrays for dual-frequency harmonic radar application, one for the transmitter and the other for the receiver. The arrays are used to track the Bogong moth that migrates from the countryside to the Australian Alps during spring. The tracking is done at the radar by operating the transmitter at one frequency and the receiver at twice the frequenc
The more urgent the climate crisis become, the more responsibility is placed on individuals to reduce their carbon emissions and become ‘sustainable consumers’. If individuals are given such a responsibility, it is important to examine whether they perceive that they can fulfill it. This thesis main aim is therefore to qualitatively examine how and to what degree income impacts people’s perceived
This study investigates the European Union’s self-perception as a global climate leader and contrasts it with the underrepresented African perspective on the EU’s role in international climate negotiations. Using a role-theoretical framework, the research analyses different leadership types and qualities, comparing European and African perceptions of the EU’s involvement in multilateral climate ch
This essay is about trust in the police organization at two time periods, the mid - and late 1990s and 2010s. In these periods the national polls pointed at a weaker experienced trust in the police compared to other time periods. Trust in the national institutions is of importance to the democratic system. National polls are however very seldom complemented by studies based on qualitative methods
This study explores how a contemporary systemic shift regarding secrecy and intelligence is affecting the strategic performance of states engaged in overt or covert intervention. These changes are conceptualized by researchers as “implausible deniability”, “delayed disclosure” and “the democratization of intelligence” and their significance are applied to limited-war theory with a theoretical focu
Agreements with SKR (Swedish Association of Local Authorities and Regions) have emerged as a significant steering instrument for the Ministry of Health and Social Affairs (MHSA). The agreements define activities for the Local Authorities to carry out and nearly always include earmarked grants. No study has yet explained why agreements are utilized as a steering instrument. Therefore, this study se
The newer spectral bands in millimeter-wave (mm-Wave) spectrum over the last few years have made higher data rates possible and improved quality of service for the users, but it possesses new challenges to design spectral agile radios. Power Amplifiers (PA) are a crucial analog component connected to Multiple input multiple output (MIMO) antennas which inherits non-linear effects. In addition, PA’
Accelerated deforestation represents a major global environmental concern. Over the last decades Cambodia has experienced a drastic decrease in forest cover and measures to halt deforestation have not been as effective as planned. In order to support reforestation, as well as appropriate sustainable forest management practices, two aspects need to be taken into account: (a) the ecosystem functioni
Hur snabbt sjunker din skit? "Hur snabbt sjunker din skit?"- är faktiskt rätt bokstavligen vad som har undersökts i detta exjobbet där inkommande partiklar på ett avloppsreningsverk har karakteriserats efter deras sedimenteringshastighet. Resultaten visar att fördelningen av hastigheter skiljde sig från ett reningsverk till ett annat. En modell av försedimenteringen baserad på en fördelThe primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. The PSTs have historically been designed based on hydraulic
The protein biomarker expressions in three types of sampled immune INFILTration spatial niches in lung cancer tissue were measured using the new technology Digital Spatial Profiler (DSP). The three types of immune INFILTration that were observed in lung tumors were STROMA identified as immune cells separate from tumor cells, Tertiary lymphoid structures (TLS) identified as dense structures of orga
I studien har jag kommit att undersöka samverkan mellan fritidshemmet och skolans musikundervisning. Syftet med studien är att identifiera vilka förutsättningar skola och fritidshem har för att samverka med musik, samt att undersöka musik- och fritidslärares möjligheter och hinder i samverkan med musik. Genom kvalitativa intervjuer med fyra verksamma lärare, två fritidslärare och två musiklärare, In this study, I have come to investigate the interaction between the leisure-time center and the school’s music education. The purpose of the study is to identify the prerequisites that schools and leisure-time centers have for cooperation with music, as well as investigating the possibilities and obstacles of music teachers and leisure-time teachers in cooperation with music. Through qualitative
As the global population continues to grow and the demand for clean drinking water in-creases, the importance of a functioning water distribution network becomes evident. In the design and planning phase of a distribution network, a hydraulic model is a helpful tool for predicting consequences of an action and defining vulnerable parts of a network. This study attempts to set up a reliable and calAs the global population continues to grow and the demand for clean drinking water in-creases, the importance of a functioning water distribution network becomes evident.

This paper examines caryatides in Greek architecture from the Archaic period to the Hellenistic period. The focus of this study is the functions, contexts, and symbolic meanings of the caryatides. Regarding the contexts, the caryatides were first used in the archaic period on the Cnidian treasury and, shortly thereafter on the Siphnian treasury, both in Delphi. In the classical period, the caryati
The main topic of this thesis is the storage location assignment problem, which can also be seen as a traveling salesman problem. The objective is to find the shortest path between items to be picked at a medium-sized warehouse. Orders come in batches consisting of items that will be assembled in-house. Therefore, it is essential to pick up all the items contained in the batch before they are drop
This essay is written with the intention to analyze in what way Nils Liljas published works Menniskan och Kärleken, can be seen as works with the intention to popularize science. What language and linguistic techniques he use in his texts will be examined, to motivate the thesis that he wrote these to reach out to a bigger crowd, than that of the academic circles in the society. With a theoretical
Adult neurogenesis is the process of generating new neurons from neural stem cells (NSCs) in the adult mammalian brain, which occurs in two neurogenic niches; the subventricular zone (SVZ) of the lateral ventricles and the subgranular zone (SGZ) of the hippocampal dental gyrus (DG). In rodents, neurogenesis continues throughout life, but this process decreases with age, which may result in cogniti
Flyktingar löper signifikant högre risk för att utveckla psykisk ohälsa, däribland posttraumatiskt stressyndrom (PTSD). Det finns en stor evidensbas som visar att traumafokuserade psykologiska behandlingar för PTSD är effektiva. Majoriteten av denna forskning inkluderar dock inte flyktingar, vilket innebär att mindre är känt om responsen för behandling av PTSD hos flyktingar. Den aktuella översiktRefugees are at significantly increased risk of mental health difficulties, including Post-Traumatic Stress Disorder (PTSD). There is a large evidence base showing that trauma-focused psychological treatments for PTSD are effective. However, the majority of trials do not include refugees and less is known about response to PTSD treatments in refugees. The present scoping review explores the curren
Klimatförändringar är en av vår tids stora utmaningar. För att kunna möta dessa finns det ett brådskande behov av att minska vart stora beroende av fossila bränslen. En lovande råvara för produktion av förnyelsebara och koldioxidneutrala bränslen är bioolja. Bioolja kan användas som ett substitut för råolja i raffinaderier och produceras från biomassa, vilket innebär att den kan agera som ett förnTo be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. One such upgrading process is catalytic hydrodeoxygenation
