The use of timber volume elements (TVEs) in residential multi-storey buildings is increasing in popularity. Manufacturing methods and building processes have been streamlined to improve product quality. However, further streamlining still remains concerning the efficiency of current calculation methods, as many developers still use simple hand calculations. The objective with this dissertation was
I denna uppsats undersöks gällande rätt avseende myndigheters ändring av sina egna beslut, och huruvida den förvaltningsrättsliga legalitetsprincipen innebär några begränsningar för myndigheters möjligheter att ändra sina beslut till nackdel för enskilda, utöver de begränsningar som följer av principen om gynnande besluts negativa rättskraft. Den förvaltningsrättsliga legalitetsprincipen enligt This essay is about the opportunities for authorities to change their decisions. The aim is to investigate the extent to which authorities can change their decisions, and to examine whether the principle of legality restricts the opportunities to change decisions to a greater extent than what is followed from the principle of legitimate expectations. The principle of legality in administrative l
It is necessary for all industries to work actively to minimize their impact on the climate, including the construction industry, which accounts for a significant part of Sweden's total CO_2-emissions. Development to produce concrete and steel with more environmentally friendly processes is ongoing, but to lower emissions immediately and achieve long-term sustainability, we need to develop met
Heterogena katalysatorer för användning i bränslecellssystem har undersökts baserat på aktiv fas och tillverkningsmetoder för granulat- och monolitkatalysatorer. Katalysatorerna tillverkades genom att använda θ – aluminiumoxid som bärare, dopad med lantan och cerium, där den aktiva fasen bestod av ädelmetall X och nickel i varierande halter. Analys gjordes genom att låta en blandning av vattenångaHeterogeneous catalysts to be used in a pre-reformer for fuel cell systems have been investigated based on active phase composition and catalyst preparation methods for granulate and monolithic catalysts. The catalysts were manufactured using θ – aluminum oxide as carrier, promoted with lanthanum and cerium, with active phases consisting of noble metal X and nickel in various concentrations. Analy
Syftet med denna uppsats har varit att undersöka hur arbetskostnad har reglerats i RUT- och ROT-avdragen (gemensamt kallat husavdragen), vilka förändringar som skett, vad som orsakat dessa och vad som kan hända i framtiden på området. Husavdragen ger en reduktion av skattebördan på köparen och en utbetalning från Skatteverket till utföraren vid vissa arbeten som utförs i anknytning till köparens bThe aim of this report has been to examine how work-cost has been regulated in the RUT- and ROT-deductions (called the house reductions together), what changes have been made, what has caused these and what can happen in this area in the future. The house reductions give a reduction of the tax burden on the buyer and a payment from the Swedish Tax Agency to the performer when certain types of work
All buildings need a foundation that supports the structure. Since a layer of soil is most often in between a structure and the bedrock, a soil-structure interaction between the foundation and the soil beneath occurs. This interaction is of great importance when it comes to predicting the sectional forces that will arise in a structure, along with the settlement that occurs. Therefore the need to
Using methods of smoothed particle hydrodynamics (SPH) an N -body simulation was set-up to investigate stellar encounters between a 1 solar-mass main sequence (MS) star, modeled after the Sun, and a 0.6 solar-mass white dwarf (WD). This was done primarily to investigate the assumptions made by Mastrobuono-Battisti et al. (2021) in search of the impact of stellar encounters on stellar population in
Turkey, the country of failed and "successful" military coups, experienced the latest coup attempt on July 15, 2016, in which it is still unclear how, why, and by whom it originated. However, after this critical event, Turkish media and critical journalists were subjected to very strict censorship and repression. Hundreds of journalists were arrested for their views, and many had to flee
Under de senaste åren har en rad plattformsföretag etablerat sig inom olika sektorer av samhället och vid det här laget är de flesta människor bekanta med företag som Foodora och Uber. Uppkomsten och den starka etableringen av gig-ekonomin har skapat en hel del oklarheter vad gäller arbetsrättsliga frågor. Gig-ekonomin bygger på en treparts-relation mellan tjänsteleverantören, användaren/kunden ocIn recent years, a number of platform companies have established themselves in various sectors of society and by now most people are familiar with companies such as Foodora and Uber. The rise and the big establishment of the gig economy has created a lot of uncertainty regarding labor law issues. The gig economy is based on a tripartite relationship between the service provider, the user/customer
This study investigates the implementation failure of the pay-per-performance SFI Bonus scheme implemented in the adult language education in Sweden. The study builds on the synthesis of a top-down and bottom-up approach by employing the 'ambiguity and conflict' model for carrying out the investigation. The key theme of this paper is that the level of ambiguity and conflict surrounding the
The purpose of this report is to evaluate the fire safety at Vasamuseet on Djurgården in Stockholm. The museum has twelve floors and consists of the ship hall including large and small exhibitions, a restaurant, a gift shop, and areas for staff. In this report, the focus is the ship hall expanding from the 2nd floor to the 7th floor. The economic and environmental loss are not taken into account
Nationell säkerhet har varit ett viktigt ämne de senaste åren och flera olika åtgärder har implementerats för att skydda stater och deras medborgare. En av dem är att utvisa utlänningar som anses utgöra säkerhetshot. Det krävs inte att utlänningen faktiskt har begått ett brott som har hotat statens säkerhet, utan det räcker att det kan befaras att utlänningen kan begå sådana brott i framtiden. DetNational security has been an important subject over the last years and several measures have been implemented to protect states and their citizens. One of them is to expel aliens that are considered security threats. It is not required that the alien actually committed a crime that threatened the security of the state, it is enough that it can be anticipated that the alien can commit those crimes
Kombucha, a traditional fermented tea beverage, is gaining popularity for its health benefits due to its bioactive compounds, especially glucuronic acid, known for detoxifying and hepatoprotective properties. Despite its significance, factors influencing glucuronic acid levels are not well understood. This study investigated the impact of initial sugar concentrations (4%, 6%, 8%) and tea types (bl
This thesis has investigated the potential of combining Raman spectroscopy with Sheimpflug Light Detection and Ranging (lidar) for simultaneous characterization and ranging of aerosolized soot. The first part of the project involved the implementation of conventional non-ranging Raman spectroscopy for both deposited and aerosolized soot. The second part constituted the design, modelling, and evalu
The use of performance enhancing drugs, especially anabolic androgenic steroids (AAS) has emerged as a social problem outside competitive sports, linked to substance abuse and crime. The purpose of this article is to analyze the use of doping and attitudes to doping outside the competitive sports context in relation to age, gender, ethnicity, so¬cio-economic status, and branch of sport. The articl
Doctoral dissertation Abstract Background The relation between mental illness and accountability, may at its best be described as unclear. A negative correlation them between was established thousands of years ago, and has since formed a more or less self-evident supposition. This dissertation is an effort to test this construction. Aims and hypothesis The overall aim of this thesis is to cla
Plants can influence methane emissions from wetland ecosystems by altering its production, consumption and transport in the soil. The aim of this study was to investigate how eight vascular plant species from mesotrophic to eutrophic wetlands vary in their influence on CH4 emissions from peat cores, under low and high N supply. Additionally, we measured the production of low-molecular-weight organ
Foliose lichens with cyanobacterial bionts (bipartite and tripartite) form a distinct assemblage of epiphytes strongly associated with humid microclimatic conditions in inland British Columbia. Previous research showed that these cyano- and cephalolichen communities are disproportionately abundant and species-rich on conifer saplings beneath Populus compared to beneath other tree species.
