Gas cooling is a technique used within the fire service to reduce the risks of the hot gaseous layer and create a better visibility. It is achieved by applying water into the gaseous layer. Successfully performing or implementing this technique is something that has not yet been accomplished in every brigade. This work has been focused on different parameters that affect gas cooling and is studie
This thesis explores the possibility for (re)defining the relationship between humans and robots with conversational interfaces. It does so by looking at the creation process of a voice and text-based virtual assistant for tourists from the perspective of critical posthumanism and posthuman performativity. In a reflexive fashion, I analyze my involvement in a tech start-up, in order to argue that,
Accidents always get a lot of public attention. Journalists appear at the site of an accident, taking pictures and making interviews with professionals and eyewitnesses. With the emergence of smartphones, online-media, and social media platforms such as Twitter, Facebook, Instagram, etc. everyone became a journalist. It is no longer only accidents catching public attention but also near misses, sm
This thesis explores the reception system for unaccompanied refugee minors (URMs) in Sweden, with a focus on preventive and responsive measures to sexual violence. The aim is to understand the professional challenges of actively working against sexual vulnerability and violence. Furthermore, it explores the interrelation between changes in laws and legislation and shifts in the public discourse, w
In this paper I have investigated what factors that may affect the recruitment, such as whether the applicant is a recent graduate, parent of young children, have been trained abroad or approaching retirement. I also want to investigate how the choice of candidates is affected if there is surplus, balance or a shortage of labor as it is for cultural secretaries, for the physical education teachers
The subject of this Master’s thesis is the management of electronic books at three Swedish public libraries. Current statistics about lending e-books have been gathered and supplemented by interviews with librarians and head librarians from the libraries in the study. Statistics and interviews are then analysed together with the library’s policy documents by using an institutional theory. The thes
Aquifers and groundwater-dependent ecosystems (GDEs) are facing increasing pressure from water consumption, irrigation and climate change. These pressures modify groundwater levels and their temporal patterns and threaten vital ecosystem services such as arable land irrigation and ecosystem water requirements, especially during droughts. This review examines climate change effects on groundwater a
I Sverige gav byggbranschen under 2020 upphov till drygt 14 miljoner ton avfall, vilket medför en betydande klimatpåverkan. För att bland annat öka mängden avfall som går till materialåtervinning och minska det som går till energiåtervinning och deponi har EU infört den så kallade EU-taxonomin, vilken syftar till att klassificera ekonomiska aktiviteter efter hur miljömässigt hållbara dessa är. SThe purpose of this master’s thesis was to study construction waste produced during construction of new apartment buildings in projects where Skanska Sverige AB has been the construction contractor. The distribution of different waste fractions and its treatment methods were studied for 15 projects, from the given data. This has been compared to the criteria given in the EU taxonomy concerning con
For a company to stay relevant in the long term, it is essential to keep up with the latest technology and continuously consider new innovative solutions for improving products and services. The gasketed plate heat exchanger (GPHE) is a mechanical device, and this work attempts to investigate different possibilities for incorporating sensor devices and predictive maintenance systems to improve the
A functioning charging infrastructure is crucial for achieving full-scale national electrification within the transport sector. The system is likely to consist of different charging technologies, all with the main objective of providing efficient energy replenishment services. Careful planning for the deployment of this infrastructure is of high importance. The consumer segments are diverse, each
The features of social media platforms not only enable the communication between citizens and political actors or institutions, in the form of comments, but also help in magnifying citizens’ voices and opinions and facilitating mass mobilization or political protests. The European Union institutions seem to understand the capacity of social media as a locus for citizen engagement, be it activism o
År 2045 har Sverige som mål att ha netto-noll utsläpp av växthusgaser. Från och med år 2019 betyder det att utsläppen måste minska med 6–10 % per år. År 2018 stod bygg- och fastighetssektorn i Sverige för 21 % av landets utsläpp av växthusgaser, vilket motsvarade 11,8 miljoner ton koldioxidekvivalenter. Om de utsläpp på 5,8 miljoner ton koldioxidekvivalenter som genererades på grund av import av sIn 2018 the Swedish construction and real estate industry accounted for 21 % of the country’s greenhouse gas emissions. In 2045, Sweden aims to reach net zero emissions of greenhouse gases. This study aimed to analyse the possibilities and the potential of reuse of construction products in new residences based on the aspects climate, cost and feasibility. Two products were selected, one due to bei
Taiwanese bridal photography is a unique practice with the goal to produce images of fantasy styles ahead of the wedding. Chosen images are displayed at the wedding banquet for the guests to admire and later used as decoration in the house of newlyweds. This visual phenomenon is interesting in that people actively take part in the creation and consumption of visual commodity and it is connected to
Since 2009, the United Nations Framework Convention on Climate Change (UNFCCC) regime has seen the emergence of several new political groups. This article analyses how the new political groups are positioning themselves in relation to the key UNFCCC principles (the North–South divide and ‘common but differentiated responsibility and respective capabilities’, CBDR/ RC). Drawing on original data, in
Could honeybees' most valuable contribution to mankind besides pollination services be alternative tools against infections? Today, due to the emerging antibiotic-resistant pathogens, we are facing a new era of searching for alternative tools against infections. Natural products such as honey have been applied against human's infections for millennia without sufficient scientific evidence. A uniqu
Lead (Pb) is one of the most important models for biomonitoring of exposure, with the blood Pb concentration as a predominant choice in practice and in epidemiology. In this article the alternatives for biomarkers to blood are reviewed. This overview focuses on a number of different qualities that are of importance in the evaluation of a biomarker's usefulness and performance. The qualities scruti
This paper contains a proposal of new Swedish framework for performance-based design of road tunnel fire safety derived from Swedish and European regulation. The overall purpose of the guideline is to protect life, health, property, environment, and key societal functions from fire. The guideline is structured into five key groups of requirements: #1 Proper management and organisation, #2 to limit
Indoor temperatures in multifamily houses are indirectly controlled by the outdoor temperature. The radiator supply temperature is a function of the outdoor temperature. This control principle cannot take into account for disturbances from people, electric appliances, airing, sun, and air leakage due to wind. A control setting with a suitable margin can avoid complaints, but may result in overheat
