Connectivity between and within places is one of the cornerstones of geography. However, the data and methodologies used to capture connectivity are limited due to the difficulty in gathering and analysing detailed observations in time and space. Mobile phone data potentially offer a rich and unprecedented source of data, which is exhaustive in time and space following movements and communication
Musculoskeletal tissues are complex hierarchical materials where mechanical response is linked to structural and material properties at different dimensional levels. Therefore, high-resolution three-dimensional tomography is very useful for assessing tissue properties at different scales. In particular, Synchrotron Radiation micro-Computed Tomography (SR-microCT) has been used in several applicati
Dynamic resource management is a difficult problem in modern microservice applications. Many proposed methods rely on the availability of an analytical performance model, often based on queueing theory. Such models can always be hand-crafted, but this takes time and requires expert knowledge. Various methods have been proposed that can automatically extract models from logs or tracing data. Howeve
OBJECTIVES: Pectus excavatum (PE) can cause both physical and psychosocial symptoms and affect patients' health-related quality of life. Previous international studies have shown that the Nuss procedure increases both self-esteem and body image. The aim of the study was to evaluate the health-related quality of life in patients who have undergone the Nuss procedure for PE. METHODS: The study had a
Background: Robot-assisted nephroureterectomy (RANU) is the primary treatment for upper tract urothelial carcinoma (UTUC) at our hospital for patients with clinical stage less than T2, and for patients with invasive tumours, but unfit for major surgery. Objective: To assess peri-operative conditions and outcomes of RANU at our unit, and to evaluate the safety of the procedure. Methods: The medical
This paper analyzes if patients’ demand for Direct-to-Consumer Telemedicine (DCT) providers is affected by a change in patient fees. The paper utilizes a natural experiment when the patient fee increased for patients in Region Stockholm using one DCT provider but remained unchanged for other DCT providers. By using DCT visits per month for all other regions as control, the effect on the demand for
ADHD is a common neurodevelopmental disorder that is defined by a pattern of hyperactivity and/or inattention that negatively affects an individual’s ability to function in everyday life. There are a multitude of challenges in correctly diagnosing ADHD. Symptoms are primarily behavior based and there are not any good biomarkers that can be used to help clinicians to diagnose the disorder correctly
This thesis is inspired by the lack of academic discourse on human rights aspects of human space settlement. It builds on the ever-growing literature on colonizing Mars and the ongoing public debate on the benefits versus disadvantages thereof. Taking on a critical approach, this thesis opens up a conversation on power, universalism, and legitimacy within space exploration, questioning both the on
A prototype of a novel 10B-based neutron detector called the Multi-Grid detector has been constructed, tested and commissioned for the European Spallation Source (ESS). The detector is constructed after the specifications set by the CSPEC instrument at ESS and is therefore called the CSPEC Multi-Grid detector. The detector uses multiple layers of solid coating containing 10B4C on the edges of a vo
This project designs an RF switch operating in E-band to provide a transmit path from a Class-F power amplifier (PA). The basic RF switch is based on the single-pole double-throw (SPDT) topology using shunt transistor switches and two λ/4 transmission line. The transistors used in this project are nanowire MOSFET transistors developed by the Division of Electromagnetics and Nanoelectronics, LTH, L
Growing amounts of waste generation in remote areas without proper waste management systems is a problem to human health and the environment. The Amazon holds the biggest freshwater resources in the world, is a biodiversity hotspot and its communities are placed in distances that can take days by boat to be reached. A National policy with EPR instruments requires private companies to take-back pac
Since the 1970’s there has been several attempts within the UN at drafting a binding instrument on business and human rights. Up until today, none of the attempts at adopting binding standards have succeeded, with the only successful initiative being the United Nations Guiding Principles on Business and Human Rights – a voluntary set of guiding principles meant to further the respect for human rig
Flooding is a major risk to the ever increasing urban population, posing a threat to human lives but also causing traffic interruptions, economic losses and pollution. Built up areas are prone to flooding due to the changes of previously pervious surfaces being covered by buildings and impervious pavements, such as asphalt. Furthermore, the resulting increased surface runoff does often not get rou
Väpnade konflikter är komplexa och mångfacetterade – män och kvinnors roller och nivå av inblandning varier avsevärt. Med detta i åtanke är det nödvändigt för internationell rätt och dess utövare att erbjuda ett reellt skydd, där ansvarsutkrävande och upprättelse erbjuds på lika villkor för alla oavsett kön. Risken är annars att vissa grupper osynliggörs. Sammanfattningsvis krävs det en nyanserad
En två-kolonn MCSGP process för upprening av Liraglutid genomfördes i laboratorieskala. Den här processen är inte en kommersiell uppreningsprocess, utan att den är ett modellsystem med en realistisk peptidblandning och med en icke-kommersiell harts. Först modellerades processen med en konvektiv dispersiv modell för att beskriva koncentrationen genom kolonnen och den steriska massaktionsmodellen föA twin-column MCSGP process for the purification of Liraglutide was implemented at lab scale. This process is not a commercial separation step, but it is a model system with a realistic peptide mixture and with a non-commercial resin. First, the process was modeled using a convective dispersive model to describe the concentration along the column and the steric mass action model to describe the ad
This master’s thesis report describes the development of a new system for control and monitoring of a helium liquefaction plant which has been carried out at Kryolab, Lund University. At the plant, helium gas is purified and then cooled in several steps until it condensates. The plant is very similar to the ones constructed today, but Kryolab wished to replace the outdated control system. The new
The U.S. decision to partner with the Kurdish militia YPG to combat ISIS in Syria has caused its longstanding ally Turkey to align with Russia and Iran, and risks doing permanent damage to the NATO-alliance, ostensibly to the detriment of U.S. national interests. Taken at face value, this seems to contradict standard notions in neo-realist theory about state behavior. Given this seeming paradox, a
The Light Dark Matter Experiment (LDMX) is a fixed target experiment that will search for dark matter, but is still in the development phase. An important aspect for the experiment is the discrimination of signal and background events. Here this signal and background discrimination is inspected using a machine learning technique called a Boosted Decision Tree (BDT). This is done using Monte Carlo
