Livscykelanalys (LCA) används för att utvärdera den potentiella miljöpåverkan av olika processer och tjänster, bland annat inom bygg- och fastighetssektorerna. Denna studie jämför tre LCA-verktyg som är speciellt utvecklade för användning inom bygg- och fastighetssektorn mot ett fjärde som är ett allmänt LCA-verktyg. En LCA görs för en fallstudie av ett flerfamiljshus där ett ventilationssystem meLife cycle assessment (LCA) is used to evaluate the potential environmental impact of different processes and services, including in the construction and real estate sectors. This study compares three LCA tools that have been specifically developed for use in the construction and real estate sectors with a fourth that is a general LCA tool. An LCA is performed for a case study of a multi-family bu

Objective: To evaluate the long-term performance of the patch materials we have used to augment the pulmonary arterial tree across a wide spectrum of diagnoses and anatomical locations. Methods: Retrospective, single-center review of 217 consecutive pediatric patients at a tertiary referral center from 1993 to 2020 who underwent patch arterioplasty of the pulmonary arterial tree from the pulmonary

PURPOSE: Autoantibodies to thyroid peroxidase (TPOAb) and thyroglobulin (TgAb) define pre-clinical autoimmune thyroid disease (AITD) which can progress to either clinical hypo- or hyperthyroidism. We determined the age at seroconversion in children genetically at risk for type 1 diabetes.METHODS: TPOAb and TgAb seropositivity were determined in 5066 healthy children with HLA DR3 or DR4 containing

Bygg- och anläggningssektorn står idag för en betydande del av Sveriges totala klimatpåverkan. En del av denna påverkan uppstår i samband med hantering av schaktmassor. Samtidigt ökar kraven för en mer hållbar framtid och en cirkulär ekonomi vilket medför att nya lösningar inom masshanteringen behöver hittas. Syftet med studien är att undersöka vilka hinder och möjligheter som finns för ökad återThe construction sector today stands for a significant amount of Sweden’s total climate impact. One part of this impact arises in regard to excavated soil. At the same time, demands for a more sustainable future and circular economy increase which in turn means new solutions regarding soil management are required. The purpose of this study is to research which obstacles and opportunities there ar

Since the Russian invasion of Ukraine in 2014, the EU and NATO have strengthened resilience, preparedness, and critical infrastructure policies in response to evolving transboundary threats. However, cascading climate risks, defined as cross-border and cross-sectoral impacts intensified by climate change, have the potential to be insufficiently understood and integrated into EU and NATO frameworks

Digital administrative systems are increasingly used in tertiary education. These systems act as the institution’s nervous system by supporting and connecting processes such as registration, attendance, grading, fees, reporting and records. However, the implementation itself does not automatically imply adoption, utilisation or value realization. In heterogeneous educational contexts the same type

Our way of handling the climate crisis is not fast or ambitious enough. We have the opportunity to plan for a better future, not just accept the consequences of our failure. To plan for a better future, we first need to conceptualise a vision of a desired end-point, in this case a climate-neutral and sustainable city. This essay is meant to inspire radical change by using and expanding the radical

This thesis explores experiences of premenstrual syndrome (PMS) and receiving medical treatment for it. Adopting a material-discursive intrapsychic model of thought, the participants' depictions are analyzed through objects, discourses, emotions and internal value systems in order to give various perspectives on PMS as well as contextualize the complex relationship between individual, group, a

Access to digital infrastructure in highly digitalized societies is shaped not only by the availability of technology but also by the administrative arrangements that govern access to it. This study examines how non-EU international students at Lund University experience and navigate exclusion from Sweden’s digital financial infrastructure through the case of Swish, a mobile payment system widely

Technical drawings play an important role in many industrial processes, including product development, manufacturing, and lifecycle management, by representing the product definition. The purpose of the study was to investigate which processes influence technical drawing creation and management, what challenges are associated with these processes, and how these challenges can be addressed through

This thesis presents the design and schematic-level simulation of a highly linear mixer-first receiver front-end implemented in CMOS, targeting improved robustness against strong input signals. The proposed architecture employs a current-mode passive mixer directly loaded by a low-impedance transimpedance amplifier (TIA) in order to minimize the voltage swing at the mixer output and thereby enhanc

Developing high-temperature proton exchange membranes (HT-PEMs) that simultaneously achieve high proton conductivity, strong phosphoric acid (PA) retention, and long-term chemical stability remains a major challenge, particularly due to PA-induced plasticization and radical-induced oxidative degradation. Here, we develop a side-chain engineering strategy to decouple PA-binding sites from the polym

With approximately 94 percent of traffic accidents being caused by human error, improving driver behaviour has the potential to save lives. To encourage safer driving, Volvo Cars is developing a Safety Coach feature for their mobile application. However, pilot studies of a minimum viable product (MVP) indicated low user retention, suggesting the need for design elements that better support user en

Heavy rainfall and cloudbursts are expected to increase as a result of climate change, putting greater demands on sustainable stormwater management. This study investigated the possibilities and challenges perceived by Swedish municipalities and water and wastewater utilities in the implementation of sustainable stormwater solutions. Additionally, the study examines how the proposed expansion of t

As data generation accelerates globally, organizations accumulate vast amounts of unused information, commonly referred to as dark data. While dark data is widely recognized as holding potential decision value, it persistently remains inaccessible, revealing a paradox between perceived importance and practical neglect. This study examines how organizations in Sweden make dark data accessible for d
