Background: Ventriculo-peritoneal (VP) shunt is a catheter which circulate flow of cerebrospinal fluid (CSF) from the lateral ventricle to the abdomen and it is the most commonly used shunt in modern neurosurgery. Complications of VP shunts are very common and often require emergency services. For the perioperative nurse this means that theVP shunt reoperation is one of the most often performed em
Syfte med uppsatsen är att jämföra kvantitativt förvaltade aktiefonder med traditionellt förvaltade aktiefonder under en 10-årsperiod, 2007–2017, samt under exceptionella chocker i form av upp- eller nedgång från 5 % i MSCI World Index. Jämförelsen gjordes med hjälp av riskjusterad avkastning i form av Sortino-kvot, Sharpe-kvot, informationskvot samt genom en regression. Endast en Sortino-maximeraThe purpose of this thesis is to compare quantitative management of stock-funds versus traditional management as a fundamental strategy, for a period of 10-years between 2007- 2017. Our essay has a special focus towards extreme market-conditions, which we defined as deviations of 5% in the MSCI World Index. Our analysis was made through the comparison of risk-adjusted measures as Sortino ratio, Sh
Cambodia´s complicated political landscape has created a development context that the international community long struggled to navigate. In this paper I – through a theoretical framework that conceptualises a political context as a historically located totality and defines the quest for political legitimacy as a constraint that can be used to make inferences about the behaviour and actions prefer
Bakgrund: En av de stora utmaningarna i Sverige idag är bostadsbristen. För att få fram fler bostäder är konvertering av kommersiella lokaler till bostäder ett alternativ. En konvertering av en kommersiell lokal med hög vakansgrad kan skapa mervärde för fastighetsägaren samtidigt som konverteringen bidrar till samhället i form av nya bostäder. Sådana konverteringsprojekt genomförs inte i särskilt
This conceptual thesis analyses Carlota Pérez vision of a ‘Green Global Golden Age’ that is supposed to reconcile the tension between economic growth and sustainability (Pérez, 2016b). Aiming to address the pressing issue of continued unsustainability, Pérez’ proposed solution is based on the assumption that technological innovation in the field of Information and Communication Technologies (ICT)
The aim of this paper is to explore which skills and mindsets are necessary for successful leadership in the digital era. It is written for IKEA who are interested in remaining at the forefront of their industry by understanding how digitalisation affects their business and how to make the most of the opportunities it brings, one aspect of which is leadership. There is a gap in the existing knowle
Anthropogenic climate change and environmental degradation demand humanity to depart from the growth imperative forming the economic structure of the world. In other words: Structural transformation is needed. Much of the sustainability debate in academy, politics, media and the public revolves around two paradigms: minor changes within the current system (e.g. green consumption, green growth) or
Block copolymer lithography is a very promising candidate for nanoscale fabrication and is economically viable. It provides a high resolution, inexpensive, and straightforward approach to nano-size patterning. In this thesis, fundamental concepts and theories of block copolymer lithography are introduced. A well-controlled dynamic solvent vapor annealing chamber is built, and the best annealing co
Coastal erosion is one of the side effects of global climate change induced sea level rise and communities have different approaches to assess coastal erosion. This study shows how three municipalities in Scania (Sweden) are affected by coastal erosion and investigates measures that are appropriate to prevent coastal erosion. The study consists of a literature study and an interview study with off
Peatlands store substantial amounts of carbon. When drainage of these areas occurs in order to use for practices such as forestry, greenhouse gases (GHG) will be emitted which will enhance climate change. The aim of this study was to explore whether rewetting of drained forest covered peatlands can reduce its impact on climate and which conflicts with forestry this can lead to. As a case study, th
Development of genetically modified microorganisms such as Saccharomyces cerevisiae for use as microbial cell factories to produce fine and bulk chemicals has lately proceeded very rapidly, much thanks to new gene editing methods based on a CRISPR/Cas9 system adapted from bacteria which increases the rate of genetic engineering. However, development of methods which enable fast and simple screenin
Rockfalls occur around Sweden every year and the country lacks a national risk evaluation and an adequate regulatory framework for construction related to this natural hazard. The aim of this study is to address this problem by mapping areas under possible threat of rockfalls, considering two fundamental aspects: i) identification of the source areas and ii) estimation of the runout zones. The stu
The majority of plastic packaging is not being recycled today, but burned for energy recovery or sent to landfill. This leads to vast losses of recyclable material, as well as elevated emissions of greenhouse gases from the extraction of fossil oil needed to sustain the production of new plastics. To be able take effective measures to increase recycling, causes of the low recycling levels first ha
Introduction: This study attempts to optimize the choice of stationary phase for the separation of lignosulfonate lignin compounds using supercritical fluid chromatography coupled to mass spectrometry. Background: Lignin is a potential renewable source of phenolic compounds. Lignosulfonate lignins are produced during pulping processes producing very complex mixtures, which are challenging to anal
Med främsta syfte att främja kommunikationen och öka patientsäkerheten vid kirurgiska ingrepp lanserade World Health Organisation (WHO) 2008 en checklista för säker kirurgi, då många studier visade att en stor del av morbiditeten och mortaliteten vid kirurgiska ingrepp var undvikbar. I Sverige framställde Landstingens Ömsesidiga Försäkringsbolag (LÖF) 2018 en modifierad version för att bättre speg
Title: Critical Supply Chain Factors for Scaling a Startup -- A Case Study in the Industry of Semiconductors Author: Pontus Landgren Supervisors: Bertil Nilsson, Lund University, Faculty of Engineering & Lennart Moberg, Acconeer AB Background: A well implemented supply chain strategy aligned with the company's overall strategy is a prerequisite in order to successfully scale a startup.
A simple and efficient approach for profiling the greenness of high performance liquid chromatography (HPLC) methods is presented. This environmental assessment tool (EAT) takes into consideration the environmental, health and safety issues for all solvents involved in the chromatographic method, and calculates a total score that can be used for comparison of the greenness of different methods. A
The deficiency or abnormal function of von Willebrand factor (VWF) causes von Willebrand disease (VWD), the most frequent inherited bleeding disorder. The laboratory diagnosis of VWD can be difficult as the disease is heterogeneous and an array of assays is required to describe the phenotype. Basic classification of quantitative (type 1 and 3) and qualitative (type 2) VWD variants requires determi
Protein S has an established role in the protein C anticoagulant pathway, where it enhances the factor Va (FVa) and factor VIIIa (FVIIIa) inactivating property of activated protein C (APC). Despite its physiological role and clinical importance, the molecular basis of its action is not fully understood. To clarify the mechanism of the protein S interaction with APC, we have constructed and express
The aim of this study was to compare the conventional combination of three-dimensional dosimeter (nPAG gel) and readout method (MRI) with other combinations of three-dimensional dosimeters (nPAG gel/Presage (TM)) and readout methods (optical CT scanners). In the first experiment, the dose readout of a gel irradiated with a four field-box technique was performed with both an Octopus IQ scanner and
