Cellulose textile fibers may be an alternative to cotton if the cellulose is first dissolved in a suitable solvent followed by regeneration through spinning. Ionic liquids have been highlighted for this purpose, and in this project, an aqueous solution of tetrabutyl ammonium hydroxide (TBAH, 40 wt%) is used for the dissolution process. The resulting mixtures have been analyzed with scattering meth
An algorithm for point group determination using moments of inertia equivalence set partitioning and geometrical properties is described. The algorithm does not generate any symmetry operation through testing, but through deduction based on geometrical properties of an equivalence set tree, and the reduction of compatible operations of this tree. The approach can handle point group determination o
The Swedish Institution of Education has recently been under debate. This is partly due to the matter that Swedish pupils’ performances have dramatically worsened. In an international study conducted through the Programme for International Student Assessment (PISA), scholastic performance scores have dropped from being substantially above average to being below average compared to the 65 other cou
The ability of microgels to adsorb to the interface of emulsion oil droplets has previously beenn reported in the literature.1 The resulting emulsions carry the thermoresponsiveness of the adsorbed microgels, and can be destabilized on demand by increasing the temperature above the volume phase transition temperature of the microgels. This thesis describes the synthesis and characterization of cro
Denna uppsats är en kvantitativ studie om 60 vuxna andraspråksinlärares förmåga till inversion i överordnade påståendesatser. Syftet med undersökningen är att se hur den språkliga kontexten samt utbildningstiden i svenska som andraspråk påverkar förmågan till inversion. Eliciteringsmetoden utgörs av ett grammatikalitetsbedömningstest som konstrueras med olika fundamentsinnehåll, finita verb och su
Syftet är att bidra med förståelseinriktad kunskap om de utmaningar som hållbarhetsfokuserade friluftsföretag står inför, för att uppnå ekonomisk vinst och samtidigt fokusera på samhälle och miljö. Vi kan konstatera att det inte finns en tydlig anledning till att friluftsföretagen har infört ett hållbarhetsarbete, men det tyder på att hållbarhetsarbetet har utvecklats med den hållbarhetstrend som
The world is increasingly inter-connected and inter-dependent as a result of the flow of goods, migration, capital movements, direct investment and the transfer of technology. To match this, politics also need to be global. The purpose of this study is to propose a policy model that will demonstrate how a country or a region can work for sustainable development and harmonize a concept of governanc
Issue of the study: Corporate social responsibility (CSR) is becoming a normal part of every corporate’s business. Companies are putting a lot of effort on sustainability and social responsibility due to an increase in regulations and demands from different stakeholders. Though there exists a gap between how much effort the companies put on CSR and how consumers perceive these efforts. Some compan
During the normal periods in absence of crisis, diversified firms without any excess cash as a whole, outperformed focused firms holding excess cash. During the Financial Crisis from mid 2007 to early 2009 on the other hand, focused firms holding excess cash outperformed less diversified firms and diversified firms as a group, where diversified firms with more than 2 different SIC codes performed
Bakgrund: Stora pensionsavgångar de närmaste åren kommer att leda till större efterfrågan av sjuksköterskor i framtiden. I dagsläget ser det ut att kunna bli brist på sjuksköterskor då det inte finns tillräckligt för att fylla den framtida efterfrågan. Det gäller att förbättra områden inom sjuksköterskeyrket som idag inte är så lockande. Vad sjuksköterskor tycker är viktigt med arbetsgivare är där
This study investigates the association behavior of microgel particles onto giant unilamellar vesicles (GUVs). The GUVs composed of 1,2-dimyristoyl-sn-glycero-3-phosphocholine(DMPC), and binary lipid mixtures of DMPC:1,2-dioleoyl-sn-glycero-3-phosphocholine(DOPC)and DMPC:1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC), were prepared by application of an alternating electric eld, in presence of
RNA interference (RNAi) plays a major role in regulation of gene expression in most eukaryotic organisms. On a basic level it is a protein complex named RNA induced silencing complex (RISC) that binds a RNA strand, a micro RNA (miRNA) or a small interfering RNA (siRNA), which guides it to its intended target, an mRNA. The RISC then disrupts translation of the bound mRNA, either by restricting it t
The evolution of new pathogens and the increase in antibiotic resistance have alerted researchers that new approaches are needed for infection management. Here we defined the epitope responsible for antimicrobial activity in the C-terminal TFPI-2 derived peptide EDC34, and showed that the net positive charge accompanied with the length of the peptide is crucial for antimicrobial activity. In addit
Football is getting more and more connected to business as well as economics by each day. Almost annually, a transfer record or an all-time-high sponsorship deal is signed. This essay will attempt to take an economic point of view on the footballing industry and try to analyze whether a relationship between seven chosen macroeconomic variables and the UEFA coefficient can be observed and defined.
Litteratur och studier pekar på att mäns köpvanor av kläder kan förklaras i att män vill handla tidseffektivt. Dessutom roar de sig inte av klädesinköp. Genom denna utgångspunkt angående mäns köpbeteende kan det anses att e-handeln skulle vara ett bra verktyg för att uppfylla de manliga köpbehoven av kläder. Statistik påvisar samtidigt att män sällan köper kläder på internet, speciellt män inom ål
A combination of acoustic trapping and impedance spectroscopy for micrometer-sized objects is here presented for the first time. Acoustic trapping has proven to be a well-functioning method for non-contact immobilization and positioning of particles or cells in microfluidic channels. The combination with impedance spectroscopy allows for simultaneous electrical measurements on the trapped objects.
In Sweden, almost every county has their public transportation handled by an individual company. The public transportation companies have their own, official, travel planner application. Which means that the appearance and functions of the applications are different. Hence, this master thesis aims to design and evaluate a new travel planner that can be used for the individual companies. The travel
A growing world population and rapid urbanization have resulted in larger cities and greater acknowledgement of the importance of sustainability, hence, sustainable cities have started to emerge. In order to cope with all factors affecting sustainability, better mechanisms for decision making in those cities are requested. The purpose of this report is to increase the understanding and fill the ga
