Ytförstärkt murverk : Dimensionering och konstruktiv utformning

Handboken är inriktad på dimensionering och konstruktiv utformning av ytarmerat lättklinkermurverk. När det gäller andra murverksmaterial, sker dimensionering på samma sätt som för lättklinkermurverk. När det gäller konstruktiv utformning av främst byggnadsdetaljer, kan särskilda aspekter behöva beaktas, beroende på murverksmaterial.Handboken har tagits fram inom ramen för utvecklingsprojektet ”De

Modeling uranium and 226Ra mobility during and after an acidic in situ recovery test (Dulaan Uul, Mongolia)

This article presents the results of groundwater monitoring over a period of six years and the interpretation of these results by a reactive transport model, following an In Situ Recovery (ISR) test on the Dulaan Uul uranium deposit in Mongolia. An environmental monitoring survey was set up using 17 piezometers, from which it has been possible to describe the changes in the water composition befor

Phase-in and phase-out policies in the global steel transition

To reach the goals of the Paris Agreement, global emissions should be reduced to net zero by mid-century. The steel sector is an emission-intensive industrial subsector where low-carbon production routes are emerging, and recent studies have shown that rapid decarbonization of the sector is technically possible. However, several barriers block the sector-wide diffusion of low-carbon steelmaking. I

Investigation of brake wear particle emissions from heavy-duty vehicles

Emissions from road transport are one of the biggest health threats during the 21st century and are therefore being regulated with Euro standards. Part of the emissions from road transport originates from brakes and brake wear particle will therefore be included in the new standards. Brake system manufacturers will have to meet the new Euro standard and potentially reduce emissions from their prod

Unveiling Immune Complexity and Regenerative Dynamics in Pleurodeles waltl: A Cross-Species Single-Cell Analysis

Unveiling the Immune System: Pleurodeles waltl and the Puzzle of Regeneration Salamanders like Pleurodeles waltl have extraordinary regenerative capabilities, these creatures can regrow limbs, tails, and even parts of their hearts, a stark contrast to humans, who have much more limited regenerative abilities. Previous studies have shown that the immune system plays a major role in the regenerati

Drivers of the small-scale spatio-temporal distribution of harbour porpoises (Phocoena phocoena) investigated via UAV around Kullaberg, Sweden

The harbour porpoise (Phocoena phocoena) is elusive and challenging to study. Recent reports indicate negative population trends in the Belt Sea population, which is found around the peninsula of Kullaberg in southern Sweden. In this study, the driving factors of the small-scale distribution of porpoises around Kullaberg were investigated by use of an unmanned aerial vehicle (UAV). Over 17 weeks f

InP/InAsP Quantum Discs-in-Nanowire Array Photodetectors: Design, Fabrication and Optical Performance

This thesis focuses on design, processing and electro-optical investigations of two- and three-terminal photodetectors based on large arraysof around three million n+-i-n+ InP nanowires with embedded InAsP quantum heterostructures for broadband detection. The first part of thethesis work dealt with a general investigation of the room-temperature optoelectronic behavior of two-terminal photodetecto

The Global South as a theoretical and methodological marker for scientific inquiry : researching and teaching decolonial peace

How do we know, theorize, and teach the possibilities of peace in the Global South? For most of Eurocentric literature on the topic, peace in the Global South seems like an impossible utopia. Building on Freire’s pedagogy, I argue for a decolonial approach to peace studies centered on the agency of Global South peoples and their power to transform the world. This means that the construction of kno

Temporality, nationalism and the territorialisation of public space : Commemorational presences in Jerusalem and Tel Aviv

In this article, I investigate how material strategies of commemoration are part of the recategorisation of public space in a series of nationalistic projects in Jerusalem and Tel Aviv. I look especially at the different ways in which these commemorative territories are made present, and the specific view of history that these presences entail. The studied cases include for example the transformat

Perioperativ intravenös magnesium tillförsel och dess påverkan på akut postoperativ smärta

Bakgrund: 75% av patienter som genomgår kirurgi upplever medel till svåra smärtor postoperativt. Akut postoperativ smärta är vanligt och nästan 20 procent av patienterna upplever svår smärta under de första 24 timmarna efter operationen, en siffra som har varit i stort sett oförändrad under de senaste 30 åren. Förutom lidandet kan otillräcklig smärtbehandling leda till många fysiologiska problem p

Operationssjuksköterskans upplevelse av kommunikation i operationsteamet- En litteraturstudie

Bakgrund: Brister i kommunikation och teamarbete hos vårdpersonal är en bidragande faktor till vårdskador för patienter. Kommunikation i ett operationsteam sker i en komplex arbetsmiljö mellan flera olika professioner som besitter olika kompetenser, där det interprofessionella teamarbetet har påverkan för patientsäkerheten. Operationssjuksköterskan är en del av det operativa teamet och ska förhåll

Nordic Microclimate Response: A study on microclimate design and its impact on seasonal life in the coastal town of Åkrehamn, Norway

This project explores the way design can adapt existing local areas to be better suited to their changing climates. In doing so it analyzes the current and seasonal climate conditions of Scandinavian towns such as Åkrehamn, Norway. Using available sun, wind, and weather data, the design is evaluated with climate modeling software to help visualize the climate conditions that the thesis aims to wor

Dwell-time station-service analysis using a Rasch analysis technique

In order to ensure punctual and robust service, it is vital to have a good understanding of the current performance of a railway network. Several approaches to doing so exist but lack the ability to compare both service and station performance in a single dimension. The study presented here proposes the use of the Rasch analysis technique within an operational context to compare the relative dwell

Superporous agarose monoliths as mini-reactors in flow injection systems

A new type of agarose material, superporous agarose, was used as a support material in an analytical system designed for monitoring of bioprocesses with respect to metabolites and intracellular enzymes. The superporous agarose was used in the form of miniaturised gel plug columns (15×5.0 mM I.D. monolithic gel bed). The gel plugs were designed to have one set of very large pores (about 50 μm i
