Epidural anesthesia is a common pain relief method that has grown in popularity over the last few decades. It is administered into the epidural space, a narrow compartment within the spinal canal. The space is localized by inserting a needle between the vertebrae. Due to the sudden loss of resistance upon entering the epidural space, combined with its narrow diameter, the procedure is difficult t
This thesis investigates the relationship between urban planning, climate adaptation, and cultural continuity in Arctic Canada, with a particular focus on remote northern settlements. While contemporary discussions surrounding resilience and sustainability are predominantly centred on large metropolitan regions, Arctic communities experience distinct spatial and infrastructural challenges that are
Building Information Modelling (BIM) in recent times has become an important tool in the building construction sector. BIM provides collaboration and information exchange for BIM-programs, however this is not flawfree, BIM interoperability is still a challenge especially during design phases in a project. This study has a purpose to identify the challenges in BIM-interoperability as well as findin
There is an established relationship between the autonomic nervous system and the variation in time intervals between consecutive heartbeats, known as heart rate variability (HRV). High HRV is associated with a flexible nervous system, while low HRV has been linked to stress and anxiety. In this study, 32 participants were exposed to four film clips (total duration of 50 minutes), two with negativ
Air quality is affected by airborne particles and gases such as PM2.5, volatile organic compounds (VOC), and nitrogen oxides (NOx), as well as environmental factors such as humidity and temperature, all of which influence human health and the spread of airborne diseases. While research grade air quality instruments provide accurate measurements, they are often large, expensive and difficult to uti
Medical devices are associated with inherent risks that may vary in severity and emerge throughout the product lifecycle. Several regulatory frameworks and standards describe how these risks should be managed, emphasizing the importance of structured and systematic risk management throughout the lifecycle of medical devices. Despite these requirements, healthcare organizations often lack clear and
Acute intracranial pressure spikes from bleeding or CSF obstructions are life-threatening, yet current intensive care relies on manual, periodic adjustments of external ventricular drains (EVDs). This time-consuming process risks severe under- or over-drainage due to varying drainage rates, highlighting the need for an automatic, volume-centered solution. This project demonstrates an automated sys
An increasing challenge in modern society is the rising prevalence of psychiatric problems among children and adolescents. Child and Adolescent Psychiatry (BUP) works with triage, treatment and follow-up of young patients, generating large amounts of clinical data throughout the treatment process. Despite this, the clinical data are currently limited used. The aim of this project was therefore to
Sleep difficulties are a prevalent health issue in Sweden, and affects nearly half of the adult population. A variety of sound-based aids are commonly used, including white and pink noise, although scientific evidence for their effectiveness is limited. This project, conducted at Lund University, explores the sonification of electroencephalography (EEG) signals into music to facilitate the process
Cardiac arrest is a life-threatening condition in which the heart stops pumping blood to the body, leading to loss of oxygen supply to vital organs. Despite cardiopulmonary resuscitation (CPR), early defibrillation and advances in emergency care, many survivors still suffer from neurological injury due to brain damage from loss of oxygen. Predicting neurological outcome, or even the chances of s
Background: Monitoring of essential physiological parameters is standard practice during magnetic resonance imaging, MRI. However, signal extraction and post-examination analysis of these parameters at SUS Lund is limited, mainly due to insufficient software capabilities. Yet researchers and physicians alike have voiced their interest in a program that manages structured and synchronized capture o
Breast cancer is the most prevalent form of cancer among women in Sweden, with 9 000 diagnoses during 2023. While the five-year survival rate reaches 92.5% due to national screening programs, transitioning from 2D Digital Mammography to 3D Digital Breast Tomosynthesis (DBT) could further improve early detection. However, the high volumes of data increases the examination times, preventing it from
Reliable ankle torque measurements are important in rehabilitation, where strength assessments are used to evaluate recovery and guide treatment. Isokinetic dynamometers, such as the Biodex system, are commonly used to provide controlled measurements of joint torque. However, these measurements rely on the ankle being held in a stable and reproducible position. Mechanical play in the ankle-attachm
One of the greatest public health challenges of our time is mental health issues, particularly the increasing prevalence among young adults in Sweden. Meanwhile, artificial intelligence (AI), which is more accessible and widely used than ever before, is being discussed as a promising tool in mental health care. This report investigates the potential of a generative AI-based chatbot to promote ment
Chronic suppurative otitis media (CSOM) is a long-term inflammatory disease of the middle ear that can cause persistent ear discharge and hearing loss. EarClean is an ear pipette intended to enable simple and cost-effective rinsing and cleaning of the ear canal. For safe clinical use, it is importantto evaluate whether the pressure generated during use may pose a risk of damaging the tympanic memb
Denna uppsats syfte var att undersöka hur fysisk smärta i samband med hormon- och kopparspiraler framställs i svensk media. Detta utförs genom en kritisk diskursanalys av 11 artiklar, publicerade mellan 2020-2025, i svensk redaktionell media som innefattar bland annat nyhetsartiklar, krönikor och reportage. Utifrån materialet analyserades tre övergripande teman: framställning av fysisk smärta, med
Future sixth-generation (6G) wireless systems are expected to support extreme data rates, massive connectivity, and high energy efficiency. Largescale Multiple-Input Multiple-Output (MIMO) combined with Orthogonal Frequency Division Multiplexing (OFDM) is a key enabling technology to meet these demands. However, OFDM signals exhibit a high Peakto- Average Power Ratio (PAPR), which forces power amp
Nationella prov i låg- och mellanstadiet infördes i Sverige 2011 i samband med den nya läroplanen Lgr11. Syftet med proven var, framför allt i årskurs 3, att agera diagnostiserande och lokalisera elever i behov av extra stöd med målet att öka måluppfyllelsen och stärka likvärdigheten. Denna studie undersöker huruvida införandet av nationella prov i lägre åldrar har uppnått de syftena. Aggregerade
This thesis examines how audience responses to the trans character Player 120 in Squid Game Season 2 are constructed within mainstream celebratory online spaces in a Mexican context. Following the release of the series, the character generated an unusually positive reaction across social media platforms, where she was widely praised and described as an example of “good” inclusion. In a context whe
