Concrete is one of the most commonly used construction material on the earth after water. The compressive strength of concrete is an important parameter and is considered in all structural designs. Production of the cement is directly proportional to carbon emissions. The cement content in the concrete can be partially replaced with waste materials like steel fibers, silica fumes, etc. Calculating

The built environment is still, to a large extent, not accessible and usable for all. The awareness of people's different conditions and abilities sometimes seems to be far from the agenda for planning and architecture. Universal Desing (UD) is pointed out as a strategy to achieve a built environment for all people regardless of age and abilities. UD has a radical potential to bring about change a

This systematic literature review assesses the current state of knowledge on how increased ICT use affects individual time-use patterns and the associated implications for lifestyle climate implications. While the environmental impacts of ICT have been widely debated in terms of direct energy consumption, there has been limited focus on the indirect time-use effects. The review draws on 101 articl

The COVID-19 pandemic and its societal impact may cause long-term behavioral changes in alcohol use due to increased psychological distress, unemployment, and time spent home. The purpose of this study was to determine whether or not the COVID-19 pandemic had a significant impact on treatment seeking for alcohol use disorders and related problems in a Swedish psychiatric treatment facility. Using

We study the possibility that the Milky Ways' cool stellar disk includes mergers with ancient stars. Galaxies are understood to form in a hierarchical manner, where smaller (proto-)galaxies merge into larger ones. Stars in galaxies, like the Milky Way, contain in their motions and elemental abundance tracers of past events and can be used to disentangle merger remnants from stars that formed in th

Biologiskt avfall till bioplast - med gröna processer av Marc Jirström Fjädrar från slaktindustrin utgör ett mycket problematiskt avfall men kan omvand- las till bioplast med hjälp av billiga och gröna kemikalier. Under detta projekt har en helt ny bioplast utvecklats, baserad på mikrofiber från fjädrar i kombination med citronsyra och glycerol - två miljövänliga och billiga reagenser. Plasten ärHandling of problematic waste material, and the use of fossil-based and non-biodegradable plastics are two major sustainability challenges. By developing solutions that convert waste material to bioplastics, it is possible to address both these issues. Every year, large quantities of feathers from the poultry industry are either stored in landfills or disposed of by incineration. The company Bioex

The purpose of this study was to highlight professionals’ views and aims of using touch screen technology, such as tablets, whilst working with people with dementia. The usage of touch screen technology whilst supporting people with dementia was found to be getting more and more common in today’s society. The study has underlined how the professionals described the tablet, what aims there were by

A novel material composition has been investigated in terms of thermal, mechanical, economical and sustainable aspects to be compared to neoprene wetsuits. It is believed that a sandwich structure produced by a dipping method with rubber layers containing an insulating textile can insulate better than foamed neoprene. The hypothesis is also that this sandwich structure can increase durability and

Ecosystem services are a way to decrease cities ecological footprint as well as adapt to a changed climate in the future. Ecosystem services are fairly new as a concept and even though it has been used within urban planning in the past it wasn’t made popular until 2005 by the Millennium Ecosystem Assessment (MA). This study pinpoints what hinders municipalities to incorporate ecosystem services in

I januari 1998 lades en del av länsväg 155 om till den nyöppnade Lundbytunneln i Göteborg. Tidigare leddes den motordrivna trafiken på denna länsväg längs bl.a. Västra Bräckevägen, Östra Bräckevägen och Stålhandskegatan. När trafiken lades om och ner i Lundbytunneln torde det bl.a. ha varit så att bullernivåerna vid nämnda vägar minskade. Det är därför troligt att marknadsvärdet steg på de närliggIn January 1998, the Lundby tunnel opened in Gothenburg. Prior to that, the motor driven traffic was routed on county road 155 (länsväg 155) along e.g. Västra Bräckevägen, Östra Bräckevägen and Stålhandskegatan. When the traffic was rerouted to go down the Lundby tunnel instead, the previous noise pollution levels caused by the traffic frictions were consequently reduced on said roads. It is a pos

During this bachelor thesis a first version of a digital tool has been formed. The tool is uniquely developed for the company Tirawa Solutions AB whose main task is to plan inspections of different railway track parts all across Sweden. The main purpose of this thesis is to investigate what functionalities are interesting to achieve a system that can display information about railway switches and

Case 2 – Godsinlösen 2016-05-04 1 Nya avfallsarenor i en cirkulär ekonomi Sammanfattning Det finns ett ord på japanska, mottainai som inte har någon bra översättning på svenska. Ordet inbegriper ett tankesätt att värdera och använda saker så länge som möjligt, något som verkar vara bortglömt i vårt västerländska slit- och slängsamhälle. Godsinlösens verksamhet vittnar om en vilja att ändra synen o

The goal of this thesis is to present a methodology for predicting time until recovery of failed wind turbines. The necessity is motivated by the potential for more accurate wind energy export forecasts. The current approach rests entirely on having an expert examine the turbine and produce a time estimate. Due to its nature, such a prediction cannot be made immediately upon failure. Five common s

This thesis critically assesses the integration of social sciences and interdisciplinarity within the international science-policy interfaces Intergovernmental Panel on Climate Change (IPCC) and Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). I depart from a theoretical framework using the concepts of academic disciplines, interdisciplinary work and scient

Bakgrund: Sociala medieanvändandet på mobilen har ökat och blivit en naturlig del av vardagen. Unga kvinnor är den målgrupp som använder sociala medier mest och påverkas mest av dess negativa effekter. Idag finns begränsad forskning kring hur aktivitetsbalansen påverkas av sociala medier. Syfte: Att undersöka hur användandet av sociala medier på mobilen påverkar upplevelsen av aktivitetsbalans hoBackground: Social media use on mobile devices is today a natural part of everyday life. Young women are those using social media the most, and are therefore also exposed to its negative effects. Today there is limited research on how occupational balance is affected by social media use. Aim: To investigate how the use of social media on mobile devices affect the experience of occupational balanc
