Purpose There is a need to find a quick way to assess the impacts of the growing amount of globally manufactured and emitted chemical substances. This paper evaluates the use of Quantitative Structure Activity Relationships (QSAR) for predicting environmental effects of plastic additives in Life Cycle Impact Assessment (LCIA). It also evaluates the impact on so called Characterization Factors (CF)
Metod: Utförandet följer studiens teoretiska ramverk, där två fiktiva portföljer konstrueras: Optimal portfölj och Minsta–Varians portfölj. Portföljernas prestation bedöms utifrån mätperioden 2002-11-30 till 2014-11-30 och jämförs mot MSCI All Country World Index. Avslutningsvis testas portföljernas statistiska signifikans för att besvara frågeställningen.
Under de senaste åren har södra halvklotet och den vidsträckta Södra oceanen fått ökad upp-märksamhet och betydelse inom det vetenskapliga samfundet med avseende på globala klimatförändringar och den globala CO2-cykeln, särskilt vad gäller förhållandena under senaste istidsmaximum (Last Glacial Maximum, LGM) och holocen. Man menar att Västvindbältet på södra halvklotet (Southern Hemisphere WesterlIn recent years, the Southern Hemisphere (SH) and the vast Southern Ocean (SO) have gained awareness and importance within the scientific community in relation to global climate change and the global CO2 cycle, par-ticularly since the Last Glacial Maximum (LGM) and into the Holocene. It is believed that the Southern Hemi-sphere Westerlies (SHW) play a key role in regulating climate change in the m
Lower through Middle Ordovician strata are described with respect to sedimentology and carbon isotope stratigraphy from two areas, viz. two outcrops at Slemmestad in the Oslo-Asker district of southern Norway and a core section from the Brunflo area in Jämtland, central Sweden. The strata at these locations are compared and further correlation is done with the Tingskullen core section from Öland,
What are the obstacles and possibilities in implementation of innovation in constructioncompanies? The purpose of the study is to highlight the barriers and possibilities that exist in implementation of innovations in a construction company. This rapport is a preliminary study to more profound innovation studies to gain a deeper understanding of the development of innovation, and the current innov
The aim of this report is to investigate how and if FDS simulations performed by experienced fire protection consultants varies in result, and how different Swedish fire protection companies works with quality assurance of calculations carried out by FDS. This was examined by allowing eight fire protection consultants from different companies simulate a specific scenario with FDS 5, without prior
Nanowires have shown great promise in the research field, however, it seems quite a challenge to get them incorporated into the silicon industry and entering the commercial field. One step towards this is to substitute the gold which is used for the catalyst particle for a different material, compatible with the silicon industry. In this project, the possibility of using in-situ nucleation inside
In this thesis I explore the relationship between the transition movement and social and ecological justice. Through a case study of Transition Guelph (TG), a transition town in Ontario, Canada, I discuss how TG creates a language based on binary concepts embedded in unequal power relations, and how this language informs their actions and activism. I also discuss how language affects their own org
This thesis provides a brief introduction of the concepts “Post-normal Science (PNS)”, “Extended Peer Community (EPC)” and “Environmental Decision Making (EDM)”. PNS is applicable when uncertainties in the interface between science and decision making are too great for traditional science and EPC is a method which is an important part of PNS. EDM is a system that tries to assist the decision maker
A Credit Default Swap spread is a reliable measure of credit risk as it is the compensation demanded by a party to bear this risk. Officially, credit risk is denoted as credit ratings announced by credit rating agencies. Since rating announcements contain information regarding credit risk, the market should incorporate this new information into the CDS spread. The aim of this study is to investiga
The aim of this study has been to investigate the technical, economical and psychological barriers for the market introduction of battery electric vehicles (BEV) in Sweden. The current situation as well as future possibilities for battery electric vehicles in Sweden has also been central to this study. The study is of a qualitative nature, and is largely based on interviews with experts from the b
Syftet med rapporten är att utvärdera hur säkerheten vid schaktarbeten kan förbättras och vilka hjälpmedel som finns för att skapa bättre förutsättningar samt bedöma påverkan ett sådant hjälpmedel skulle ha på framdriften. Genom litteraturstudier belysa risker med schaktningsarbetet och hur planeringen går till för att skapa rätt förutsättningar. Genom dokumentstudier, observationer och intervjue
The fermented tea beverage kombucha is a traditional drink that has been consumed for thousands of years in Asia. Over the past decades, it has gained greatly in popularity amongst consumers and researchers also in the rest of the world. Kombucha is produced through fermentation of sweetened tea by a complex community of bacteria, mainly dominated by acetic acid bacteria, and a variety of yeast. D
Freevalve AB develops camless valvetrains for internal combustion engines using pneumatic and hydraulic systems. An air compressor is used to generate pressure in the pneumatic system. To further increase efficiency of the Freevalve system, a new compressor tailored to its purpose, is being developed in house. This thesis is part of the development of this compressor, which is a reciprocating pis
As technology advances and population rises, requirements for everyday doors change. In the industrial sector, companies have to keep up with the increase in supply and demand. A well-functioning industrial folding door contributes to a steady flow of goods. Folding doors come in many different sizes and are often installed in narrow spaces. In order for any door supplier to stay competitive, offe
Introduction: In this work, oil from Baobab seeds was extracted and analysed in order to determine how much oil the seeds contain and the fatty acid composition of the seeds. Background: A lot of seeds go to waste when either producing drinks of Baobab fruit or simply eating the fruit raw. Thus, it would be favourable if it was possible to produce a product based on the left-over seeds, suitably
This study focuses on the relationship between education and economic growth, specifically the effect a potential decline in schooling caused by the ongoing Covid-19 pandemic would have on the economic growth of a country. Using an inductive approach, the study focuses on the Sub- Saharan African countries, especially Kenya, since there is anecdotal evidence that a significant number of students h
