Currently most aromatic compounds used in industry are derived from unsustainable petro-chemical feedstock. However the depolymerization of lignocellulosic biomass generates a wide range of aromatic compounds that could be further valued through microbial conversion with microorgansims such as the bacterium Pseudomonas putida. The aim of the present project was to develop a reproducible methodolog

The purpose of this journal is to further investigate how a brand, during a limited time frame, can change an unwanted image by challenging the stereotypical perceptions of their brand by adding an element of surprise. The research is conducted through a multiple-case study consisting of four cases: Mercedes-Benz, Opel, McDonald’s and Lidl. A resulting matrix has been developed to demonstrate the

Background/introduction: E-commerce is becoming a natural part of retail business. In order to achieve a competitive edge, companies are shifting to omni channel retailing where channel integration is explored in the search for potential improvements in connection with customer offer and costs. One solution is to integrate inventories and offer improved order fulfilment by using both warehouse and

Purpose: The aim of this paper is to explore how brands’ greening strategies affect consumers’ green brand image. Design/Methodology/Approach: This study is based on a qualitative approach, researching one case, McDonald’s greening strategies compared with the consumers’ brand image. The consumers’ brand image was collected with the help of 12 semi-structured interviews. Findings: The research s

Pavements in Sweden today are often designed to have a life span of at least 20 years. This means that pavements are designed to endure all seasons for 20 years: 20 winters, 20 spring thaws. 20 summers and so on. For those occasions where a life span less than 20 years is requested, there is no standardized method to use today. Designing is instead usually done either by scaling down the results f

The aim of this essay is to investigate two scholastic theologians’ views on usury, to compare their arguments for the Christian usury prohibition and to see whether one can see a development in argumentation. The examined writers are St. Thomas Aquinas and Gerard of Siena and their works Summa Theologiae, De Malo, and De Emptione et Venditione; and De Usura, respectively. Before the investigation

Vad är det som gör att en människa är benägen att utsätta sig för de risker som finns i att vara kriminell, vad är mentaliteten under tiden och hur kommer man ur det. Uppsatsen berör processen för individer som valt att inleda, upprätthålla och avsluta en kriminell karriär. Detta undersöks genom intervjuer med fyra stycken före detta kriminella personer. Genom denna kvalitativa uppsats söktes pers

De senaste årtiondenas utveckling av svensk arbetsmarknad och arbetsmarknadspolitik har gjort att fler grupper förväntas klara sin försörjning genom arbete. Flera förändringar har genomförts som tillsammans innebär att fler arbetslösa blir kommunernas ansvar vilket har lett till att allt fler kommuner i växande utsträckning bedriver arbetsmarknadsåtgärder. För personer som anses befinna sig längst

Algoritmer för att automatiskt förstå innehållet i bilder och videor har sett en enorm utveckling under de senaste åren. Trots framsteg i hur väl algoritmerna kan läras till att förstå bildinnehållet på egen hand så krävs fortfarande en viss grad av handhållning och vägledning från områdesexperter som utvecklar och tränar algoritmerna. När positionen och dimensionerna på ett objekt av intresse skaThis thesis presents a novel matching strategy, Inflated Multinomial Matching, which enables training of anchor-free object detection models based on convolutional neural networks. An important aspect of detection models is the integral usage of anchor boxes, where an anchor box is a bounding box with a preset and constant location, size and shape in the image. The matching strategy presented remo

Transparenta material som kan leda ström är viktiga för bland annat solceller. Nu har ett sådant material, indiumtennoxid (ITO), för första gången tillverkats i rekordliten storlek för att användas till exotiska solcellsprover på nanoskalan. ”Konventionella” solceller lider av ett problem som kan liknas vid grötproblemet Guldlock stötte på hos de tre björnarna: när solen lyser på solceller kommerNanowires have attracted interest as fundamental building blocks for electronic and optoelectronic devices as well as for fundamental research. Photonic studies of single nanowire devices typically involve patterning of metal electrodes for electronic access, yet plasmonic ef- fects between the metal contacts and the light source may perturb experimental measurements. An alternative to conventiona

The aim of this thesis is to suggest a statistical model to estimate the loss rates of honey bees during winter in Sweden. The estimator is to be based on annual summary statistics, collected by the Swedish beekeeping organisation. Regional specific estimates for winter loss rate is derived by a spatial and temporal hierarchical model with binomial response. The model is updated by Bayesian infere

We investigated the performance of basic jet subtraction, by the utilization of jet reconstruction generally used at the Large Hadron Collider (LHC). This was done by studying Z-bosons, in the dielectron decay channel, and the associated jet correlation in pp, pPb and PbPb collisions, using datasets generated by the Monte Carlo generator PYTHIA8. The PbPb collisions at $\sqrt{s_{NN}} = 2.76$ TeV a

Statistics in Sweden show that more than 160,000 people applied for asylum in 2015 alone. Out of that number, over 35,000 applicants are unaccompanied minors ( Migrationsverket , 2016). The work around these minors is of utmost importance to ensure they can integrate to the society and become self-sufficient in the future. Under crisis conditions, allocating resources in the most effective and eff

While the general process of mineralization and bone formation during embryogenesis is well understood, little is known about the detailed mechanisms and the structural and compositional characteristics of developing bone. At present, studies on fetal bones have been conducted, but most of these studies have been on the macro- and microscale. Bone tissue constitutes of an organic and inorganic ma

Mode står likt arkitektur med ena benet i konsten och det andra i funktionen. Mode är allt från en tröja som håller dig varm till en haute couture-klänning som snarare är att betrakta som konst. Kläder bär vi alla och därmed berör mode fler människor än annan kultur såsom konst och film. Ändå upplever jag att mode ses som en kulturyttring med lägre dignitet och ofta avfärdas som fånigt och ytligt.

I denna studie utvärderades tre metoder för att utvinna DNA ur bakterier från sex personers tarmflora. Slutsatsen blev att kit extraktionen var den bästa metoden, men att personen som provet kom ifrån påverkar resultaten mer än själva metoden i sig. Celiaki är en så kallad autoimmun kronisk sjukdom vilket innebär att immunförsvaret angriper tarmens slemhinna som ett gensvar på absorberat gluten. GCeliac disease is a chronic autoimmune disease which affects about 3 % of children in Sweden where most of them have an asymptomatic form making it difficult to detect. The bacterial composition in the gastrointestinal microflora can affect the intestinal barrier properties and the immune systems response to various dietary components. An unfavourable composition of the microflora can activate par

This master thesis, completed at the company Alfa Laval studied the surface properties of grade 1 titanium from two different suppliers to examine if there were any significant differences between the two suppliers. Previously titanium from the two suppliers had performed differently at times when used in Alfa Lavals heat exchangers. The experiments performed where studies of surface energy, surfa
