Noise pollution generated by drones has in recent years become a concern for humans and wildlife and has in some regions resulted in regulatory backlash. This thesis investigates the possibilities of developing a low noise drone propeller using computational fluid dynamics (CFD) simulations. A commercial drone propeller from the manufacturer APC Propeller has been modified with different forms of

The development aid field has been subject to increased questioning regarding power relations between donors and recipients; some studies shed light on the fact that development aid is an extension of colonial practices. Currently, there have been efforts to ‘decolonize aid’. This thesis studied Sweden’s and United States’ national development agencies’ policies, Sida and USAID respectively, regar

Abstract: This research explores the experiences of Somali woman students, to gain an understanding on how the subgroup interacts within and around campus, in relation to their race, gender and cultural identity. This research aims to acknowledge the multiple barriers and factors which may aid or hinder their experiences. The findings allowed for thematic analysis. The study observed that the par

Civil liberties and freedoms have diminished globally due to the last decades’ deepened authoritarianism. Concurrently, mobilizations countering this development have decreased. Hong Kong represents one of the cases where anti-authoritarian resistance has been sustained, which sparks a question regarding what motivates people in expanding authoritarian spaces to engage in contentious politics. Thi

Partikelkollisioner gör det möjligt för oss att studera de inre strukturerna och beteendena hos partiklar som utgör universum. År 1969 upptäckte forskare att protoner faktiskt består av mindre partiklar som kallas kvarkar genom kollisioner mellan elektroner och protoner. Så genom att kollidera partiklar så får vi ut hur dessa partiklar påverkar varandra men också som i fallet för protonen, vad de In high energy physics, we want to probe the inner structures and behaviours of the particles that are the building blocks of our universe. This is often done by colliding nuclei together. This bachelor thesis presents an implementation of a Glauber Monte Carlo simulation framework to determine the geometric quantities such as the number of participating nucleons $N_{part}$ and the number of sub-c

Aims and objectives: To explore what it means for parents to participate in their children's paediatric perioperative care. Background: Allowing parents to participate in paediatric perioperative care can make a major difference for children in terms of their well-being, a decreased need for painkillers, fewer sleeping disorders and a more positive experience for both parties. The nurse anaestheti

Utvärdering av sensorers noggrannhet och repeterbarhet i packningsförsedda plattvärmeväxlare. Som en del av Alfa Lavals digitaliseringsprocess erbjuds nu kunder möjligheten att koppla upp sina värmeväxlare med sensorer. Informationen som samlas in gör det möjligt för kunderna att undvika oplanerade reparationer, öka deras processers drifttid och därmed minska kostnader och risk. Om värmeväxlarna Alfa Laval has connected sensors to their gasketed plate heat exchangers (gphe) to extend their customer service offering. To develop this service further the flow through the GPHE is needed. In this thesis, the objective was to evaluate an inexpensive flow switch and two sensor kits that measure pressure and temperature. The sensors were assessed by installing them on GPHEs in Alfa Laval’s lab an

In most Muslim-majority countries, Islamic normativity underwent a process of “positivization” completely altering the sense which is made of these norms and the ways through which they are obtained. This article aims to deepen our understanding of this phenomenon through a comparative examination of an issue addressed in classical fiqh, partly legislated in modern statutes and codes, sensitive to

Denna undersökning avser att undersöka och belysa livsmedelssäkerheten inom studentnationerna vid Lunds universitet i Lunds kommun och Uppsala universitet i Uppsala kommun. Huvudfrågeställningen som behandlas är "Är maten som serveras vid dessa studentnationer säker att konsumera?". En metodik som omfattar granskning av kontrollrapporter, enkätundersökningar och litteraturundersökningarThis thesis aims to explore and shed light on food safety within the student nations at Lund University located within Lund municipality and Uppsala University within Uppsala municipality. The main question being addressed is, "Is the food served at these student nations safe to consume?". A method surrounding review of control reports, survey research, and a literature review has been

Aim: Rare genetic variants in the CUBN gene encoding the main albumin-transporter in the proximal tubule of the kidneys have previously been associated with microalbuminuria and higher urine albumin levels, also in diabetes. Sequencing studies in isolated proteinuria suggest that these variants might not affect kidney function, despite proteinuria. However, the relation of these CUBN missense vari

Background: Hallux rigidus (HR) affects the first metatarsophalangeal joint and is the most common osteoarthritic condition in the foot. The most used surgical treatment for severe cases of HR is an arthrodesis. The aim of this study is to describe patient characteristics, surgical treatment and the patient-reported outcomes for patients treated with arthrodesis for HR using data from Swefoot, the

Det är av stor vikt att få en förståelse för vad sjuksköterskor upplever när patienten försöker begå suicid och vilket stöd de behöver för att klara arbetet. Syftet med studien var därför att beskriva sjuksköterskors upplevelser av att möta patienter med suicidalt beteende inom psykiatrisk vård. Studien genomfördes som en litteraturstudie med induktiv ansats och innefattar åtta vetenskapliga artik

BAKGRUND: Kraven på sjuksköterskan ökar ständigt, vilket kan leda till en osäkerhet i yrkesrollen. Hur livserfarenheter har påverkat yrkestryggheten belyses i denna studie som tar avstamp i KASAM-teorin med begreppen begriplighet, hanterbarhet och meningsfullhet. SYFTE: Att belysa sjuksköterskors upplevelse av livserfarenhetens betydelse för yrkestryggheten. METOD: Sju sjuksköterskor inom somati

There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues
