Att människan påverkar klimatet och att utsläpp av växthusgaser värmer planeten är ingen nyhet. Byggsektorn stod 2015 för 18 % av Sveriges totala utsläpp av växthusgaser och 2018 lanserade Bygg- och anläggningssektorn en färdplan för att nå en klimatneutral värdekedja tills år 2045. Tidigare studier har pekat på att majoriteten av klimatpåverkan ifrån flerbostadshus kommer från driftskedet, men seThe emissions of greenhouse gases caused by the construction sector represented 2015 18 % of Sweden’s total greenhouse emissions and the sector had by 2018 published a plan on how to reach a climate neutral value chain by 2045. Studies have shown that the construction phase has become a larger part of the climate impact from new-built multi-family residential buildings than before, in, in relation

The 1914 eruption of Sakurajima (the Taisho eruption) caused catastrophic consequences by releasing enormous volcanic ash to Japan’s atmosphere, affecting both proximal and distal regions. As volcanic ash is a complex hazard that can cause damage to critical infrastructure and disrupt socio-economic activities, impacts from such an eruption in contemporary Japan will be more severe than in 1914. D

Background: Increased nasal resistance as measured by 4-phase rhinomanometry is associated with a paucity of apneas relative to hypopneas in obstructive sleep apnea (OSA) patients. The ratio of hypopneas to apneas for a given apnea hypopnea index (AHI) may influence treatment choice. This study aimed to investigate if OSA patients with an elevated hypopnea apnea ratio are associated with differenc

Autopsy data indicate that the locus coeruleus (LC) is one of the first sites in the brain to accumulate hyperphosphorylated tau pathology, with the rostral part possibly being more vulnerable in the earlier stages of the disease. Taking advantage of recent developments in ultra-high field (7 T) imaging, we investigated whether imaging measures of the LC also reveal a specific anatomic correlation

Background: Children with right ventricular outflow tract (RVOT) anomaliestypically undergo surgical repair during their first months of life and thereafter they will need one or more reoperations through their life.Aims: The overall aim was to describe health-related quality of life (HRQoL) forchildren with congenital heart disease (CHD) with a special focus on children withRVOT anomalies and to

PD-L1 expression assessed by immunohistochemical staining is used for the selection of immunotherapy in non-small cell lung cancer (NSCLC). Appropriate validation of PD-L1 expression in cytology specimens is important as cytology is often the only diagnostic material in NSCLC. In a previous study comprising two different cohorts of paired biopsies and cytological specimens, we found a fairly good

BACKGROUND: The HIV epidemic in Ethiopia is concentrated in urban areas. Ethiopia conducted a Population-based HIV Impact Assessment (EPHIA) in urban areas between October 2017 and April 2018 to measure the status of the country's response to the epidemic.METHODS: We conducted field data collection and HIV testing in randomly selected households using the national, rapid testing algorithm with lab

Infections by pathogenic microorganisms remain one of the most serious concerns in several areas, particularly in hygienic applications. Antimicrobials have been used to combat these infections. Using small molecular antimicrobials as additives or coatings is an industrially adopted strategy. However, small antimicrobial agents always suffer from many drawbacks, such as leaching potential, toxicit

Background: The aim of the study was to demonstrate the safety and effectiveness of a suture-mediated vascular closure device to perform hemostasis after an axillary artery access during endovascular procedures on the aortic valve, the aorta and its side branches. Methods: A physician-initiated, international, multicenter, retrospective registry was designed to evaluate the success rate (VARC-2 re

In a non-negligible number of patients with metastatic colorectal cancer (mCRC), the peritoneum is the predominant site of dissemination. Cure can be achieved by cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), but this procedure is associated with long-term morbidity and high relapse rates. Thus, there is a pressing need for improved therapeutic strategies and co

A parent’s life threating illness and death can significantly affect their children's wellbeing in both the short and long term. Support from professionals is recommended when parents lack the ability to help children cope with loss, bereavement, and grief. The overall aim of this dissertation was to illuminate professionals’ encounters with children of a seriously ill or deceased parent and to ex

Background: The aim of this study was to assess whether hypothermia increased survival and improved functional outcome when compared with normothermia in out-of-hospital cardiac arrest (OHCA) patients with similar characteristics than in previous randomized studies showing benefits for hypothermia. Methods: Post hoc analysis of a pragmatic, multicenter, randomized clinical trial (TTM-2, NCT0290830

Purpose: An ageing population presents a challenge for municipal eldercare in Sweden due to difficulties recruiting staff and there being a strained economy. A strategy involving welfare technology is presented as one such solution. An important group to carry out this strategy involves those who work with welfare technology in municipal eldercare. In this paper we describe their perception of wel

This thesis describes the work done on two open access microcavities that aims at detecting single rare-earth ions for quantum information applications. The initial microcavity faced mechanical instability due to its geometry, which limited robust design possibilities due to the 25 mm diameter space of the helium bath cryostat. A Purcell enhancement of 2.2 was realized for nanoparticles at 2.1 K,

This article explores how quantitative organological analysis can be implemented alongside historical musicology to help stimulate creativity in performance practice while promoting a diversity of timbre that is often lost amidst the hegemonic propagation of homogenized, normalized modern musical instruments. The tuba family provides an insightful case study demonstrating how the history and devel

This thesis consists of three independent research papers. Using both applied econometric methods and theoretical models, they study the functioning of electricity markets, including those for green certificates, and auction markets in the presence of policy and market imperfections. The first paper empirically examines the effect of regulatory uncertainty in quota-based green certificate markets,

INTRODUCTION: A recent study on patients with acute lower limb ischemia showed that the proportion of inadequate examination of lower extremity circulation was associated with higher rate of amputation and death. The aim of this systematic review was to explore evidence for how practical competence in performing a peripheral vascular status of the lower limb among medical students and junior docto

Occupancy is one of the primary contributors to the energy performance gap, defined as the difference between actual and predicted energy usage, in buildings. This paper limits its scope to residential buildings, where occupant-centric consumption often goes unaccounted for in standard energy metrics. This paper starts from the hypothesis that a simple occupant energy efficiency label is needed to

New-generation single-layer polytetrafluorethylene (PTFE-) or polyurethane (PU-) covered stent (CS) for the treatment of coronary artery perforation (CAP) during PCI offer high procedural efficacy. To evaluate the comparative long-term safety and efficacy of both devices. This is a multicenter pooled analysis of individual data of patients with CAP undergoing implantation of single-layer PTFE-CS o

This study examines how small and medium-sized, logistically prominent cities with climate ambitions govern their urban freight systems toward sustainability. It provides a framework for analyzing cities' governance from a socio-technical transition perspective and explores the interrelations between governance activity design and city administrations' capabilities to manage system development.
