A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was succes
Three new cobalt complexes of the general formula [CoIII(L)Cl]2+, where L is one of five pentadentate nitrogen-donor ligands based on the N4Py framework, have been synthesized and characterized fully by UV−visible and NMR spectroscopies, high-resolution electrospray ionization mass spectrometry (HRESI-MS), X-ray crystallography, and electrochemistry. The electrocatalytic capabilities of these comp
Syftet med uppsatsen är att redogöra för faderskapspresumtionen samt att undersöka om det är en lämplig metod för att fastställa faderskap. Faderskapspresumtionen härstammar från den romerska rätten och innebär att om modern är gift vid barnets födsel, förutsätts hennes man vara barnets far. Är modern ogift fastställs faderskapet genom bekräftelse eller dom. Historiskt sett har faderskapspresumtioThe purpose this essay is to give an account of the presumption of paternity and to investigate whether it is a suitable method for establishing paternity. The presumption of paternity is a legal concept that generally assumes the husband to be the father of any child born during the marriage. The presumption has been a longstanding legal principle and originates from Roman law. If the mother is u
The purpose of this thesis is to further investigate the state of matter known as Quark-Gluon Plasma (QGP) that is produced in heavy ion collisions. This is done by analyzing jets and jet quenching in Pb-Pb collisions at $\sqrt[]{s_\textrm{NN}}$ = 2.76 TeV from ALICE. The events are discriminated by setting a 8 GeV/$c$ $p_\textrm{T}$ threshold on the trigger particle. This ensures that there is ha
Urbaniseringen innebär att det blir mer och mer hårdgjorda ytor i städer, vilket ökar belastningen på dagvattennätet. Vidare så innebär klimatförändringarna ytterligare utmaningar då nederbörden i Sverige antas öka. För att hantera detta föreslås hållbara dagvattenlösningar varav gröna tak kan vara en del. Detta skapar ett behov att på ett enkelt sätt modellera avrinningen från gröna tak. I detta The increasing urbanization means there are more and more impermeable surfaces in cities. This is straining the capacity of the stormwater network. Furthermore, climate change is assumed to bring about more precipitation in Sweden in the future. In order to deal with these challenges a sustainable approach to stormwater management is needed. Green roofs can be one part of the solution. This create
The NDVI time-series consist of trend, season and noise. Changes in the season component are related to climate factors and they happen gradually over long period of time. The changes in the trend component are often due to human activities, fires and etc. This paper implements two algorithms (PolyTrend and DBEST) in R language, in order to examine the vegetation changes in the Middle East and to
In applications of real time gesture detection on devices which have cameras and limited power supply it is important to consider both robustness and maintaining a low power consumption. A well explored approach is the use of cascades of boosted classifiers. As retraining is a very cumbersome process, online environment adaption would be an appealing approach to counter situations where the booste
För mindre och nystartade aktiebolag kan finansiering vara ett gissel, särskilt om den verksamhet som bedrivs i bolaget är kostsam eller förenad med hög finansiell risk för potentiella finansiärer. Sådan är situationen ofta i det som i folkmun kallas ”startups”, då bolagen frekvent bygger på enbart en idé eller en outvecklad produkt, och därmed utgör mycket osäkra investeringar för poten- tiella f
The concept of social sustainability is difficult to define and is often perceived as broad. The aim of this thesis is to narrow it down, in a perspective concerning the Right to the City. The thesis also aims to examine how planning for the Right to the City in conjunction with social sustainability, through planning for social mix, might lead to a process of gentrification. The object of the stu
An ongoing discussion in Sweden regards the reduced green areas as a consequence of urbanization and housing shortages. Previous research emphasizes positive effects that nature has to our health. Public outdoor environments such as playgrounds or parks are the basis of children's play in their neighborhood. To plan and create good environ-ments, for children to grow up in, is therefore necess
The study looked at a group of young men convicted of violent crimes and had a particular focus on Conduct disorder (CD) as well as differences in background and treatment interventions (therapy or medication) depending on whether the person had early, late or no CD. The aim was to identify how these treatment measures differed between the groups early, late and no CD. Data to the current study ca
The purpose of this paper was to research how environmental concerns and sustainable thinking could be integrated into the design process of Electrolux, a Swedish home appliance manufacturer. The research will hopefully help the Electrolux industrial design department improve in the area and prove as a good case study for other companies or academic institutions. Electrolux conducts much research
Syftet med studien var att få en större inblick i vad sjuksköterskestudenter anser vara attraktiva egenskaper på en arbetsplats och vad de har för upplevelse av Region Skåne. Motivationen kom från den rådande sjuksköterskebristen. En enkätstudie, baserad på Åteg et als. modell om attraktivt arbete (2004) utfördes. Respondenterna har besvarat dels hur viktiga dessa items är för en arbetsplats attra
This thesis evaluates the potential for machine guidance in winter road maintenance. The proposed benefits would be a reduction in material- or time needs. It should also reduce accidents with benefits for both property damages and personal injuries. The work methods and organisational structure of winter road maintenance is described through literature studies and interviews. The interviews are d
The phase field method emerged as a tool to solve free boundary problems with a sharp interface. In previous methods, this involved the computationally inefficient and complicated tracking of a moving interface. The phase field method overcomes this limitation by introducing an auxiliary variable called the order parameter which varies continuously over the whole domain and takes on finite values
The main purpose of this paper is to find if there are any differences between the two Scandinavian countries Sweden and Denmark in help institutions for women in prostitution. Buying sexual services has been illegal in Sweden since 1999. There are no similar regulations in Denmark. By employing a comparative study method, information from the two countries have been broken down through content a
