The laccase producing fungus HC1 was isolated from a sample collected in the Bolivian Amazon region. Analysis of 5.8S and 28S rDNA, and internal transcribed spacer 1 and 2 sequences revealed that isolate HC1 belongs to genus Galerina. High production of laccase was achieved in basal salt medium supplemented with 30 g L-1 glucose, 10 g L-1 yeast extract and 0.01 g L-1 copper sulphate. The enzyme pr

One of the most effective methods for obtaining bulk ultrafine-grained materials is severe plastic deformation that is typically done using equal channel angular pressing. In this work we describe and analyze a new method for obtaining severe plastic deformations proposed by the first author. The method is based on direct extrusion and was called "twist extrusion" The main idea of the method is to

För att bygga ett starkt varumärke krävs enhetlighet och starka värden som delas av samtliga medarbetare inom organisationen. Om tolkningsfriheten då blir för stor leder det till att olika värden och känslor kopplas till varumärket. Olika tolkningar kan sätta sig på olika delar av organisationen, vilket i sin tur förmedlas på ett inkonsekvent sätt till kunden.

Background: Increasing cost effectiveness and productivity are key issues for Haldex. These improvements are obtained through Haldex Way, the overall management and process improvement framework. Haldex Way‟s deployment, progression and assessment are based on a five level Tier model, the concern with Haldex Way Tier model is that its evolution has been inconsistent and the Tier levels have been a

This thesis in collaboration with ESS proposes a workflow for developing, deploying, and integrating machine learning models into the control system. Machine learning offers a promising potential for control systems but often introduces technical debt, with the actual model code representing only a small fraction of the total code base. To address this a data-centric process is proposed for retrie

This thesis investigates the effects of monetary policy on investments by venture capital firms. Modeling central banks’ interest rates and various macroeconomic variables on venture capital investments, we find a statistically significant relationship whereby expansive monetary policy is correlated with more investment in startups by venture capital. The panel data models use data from 2000 to 20

Syftet med studien är att undersöka hur revisorer gör sina professionella bedömningar och därigenom skapa en djupare förståelse för varför revisorer tolkar och granskar företags finansiella rapporter på detta sätt. Denna tvärsnittsstudie grundar sig i konstruktivism där materialet samlats in enligt kvalitativ forskningsdesign. Vidare bidrar uppsatsen med ett hermeneutiskt synsätt på revisorns be

Forskningsfrågor: Hur positioneras och marknadsförs vitt snus i Sverige? Vilka budskap sänder vita snusvarumärken i sin reklam och vilka är dessa budskap riktade till? Syfte: Syftet med studien är att beskriva hur det vita snuset är positionerat och marknadsförs på den svenska marknaden för valda fallföretag samt undersöka vilka budskap de sänder, för att bidra till teorin med insikter om positionResearch question: How is white snus positioned and marketed in Sweden? What messages do white snus brands convey in their advertising, and who are these messages targeted towards? Purpose: The aim of the study is to describe how white snus is positioned and marketed in the Swedish market for selected case companies, as well as to examine the messages they convey, in order to contribute to the the

The global business environment has changed rapidly during the past decades; part of that change is the concept of Born Globals. Small and emerging companies are deviating from the traditional globalisation models with incremental steps to internationalisation in favour of turning global from inception. When a Born Global firm acquires Venture Capital, new demands on efficiency and returns are set

Vindkraftverk är ett av samhällets främsta verktyg för en miljövänlig energiproduktion. Den konventionella designen av bladen är emellertid i stort sett oförändrad. Triblade är ny typ av design som har potentialen att revolutionera marknaden. Genom att använda en fackverksstruktur öppnar man för möjligheten att utforska andra materialval än de konventionella kol- och glasfibermaterial som anväIn the 21st century, wind power has emerged as a strong candidate in fulfilling societies goals of achieving carbon-free energy energy production. Windpower has evolved along with other technological developments, giving rise to larger turbines, but with the overall design trend remaining largely unchanged. Winfoor, a Swedish company based in Lund,aims to break that trend. With their new Triblade

Dagens Nyheter etablerade under våren 2022 lokala redaktioner i Luleå och Umeå med syftet att förmedla nyhetshändelser från Norrland till en rikspublik. Sedan uppstarten i mars 2022 till tidpunkten för genomförandet av denna studie har runt 180 artiklar producerats av redaktionens reportrar. Syftet med studien är att undersöka hur Norrland representeras och gestaltas i Dagens Nyheter och ifall etaDuring the spring of 2022, the Stockholm-based newspaper Dagens Nyheter established two newsrooms in the cities Luleå and Umeå located in the north of Sweden. The purpose was to communicate news events from Norrland to a national audience. From the start of the newsrooms until the time of this study, around 180 articles were published. The aim of this study is to investigate how the region of Nor

This article studies a hitherto unexplored dimension of the Chinese Civil War: the disparity between modern military technology and the conceptual and logistical capacities of the two warring sides. The author argues that the advanced weaponry, received by the Nationalists from their ally, the United States, but often captured on the battlefield by the Chinese Communist Party (CCP) forces, proved

The content of the globular domains G1, G2 and G3 on the core protein of high-density (A1D1) aggrecan isolated from newborn and mature bovine cartilage and from cultures of bovine chondrocytes was examined. Quantitation based on the 220 nm absorbance of tryptic marker peptides from each domain isolated by reversed-phase HPLC showed that while the content of G1 and G2 was essentially the same for a

Syfte: Uppsatsen syfte är att utöka förståelsen kring huruvida fakulteter vid ett universitet arbetar med sin märkesidentitet med hjälp av internal branding för att differentierar sig i en värld där konkurrensen hårdnar och ackrediteringar riskerar att likforma fakulteterna. Metod: En kvalitativ studie har genomförts med ett hermeneutistiskt fenomenologiskt förhållningssätt. Den analys och slutsaPurpose: The purpose of this thesis is to bring awareness whether the faculties at the universities is working with its brand identity by using internal branding in order to differentiate themselves, in a world where competition is intensifying and where accreditations threaten to uniform the faculties. Methodology: A qualitative study has been conducted with a hermeneutic phenomenological approa

This thesis experiments with the data structure of a sparse voxel octree (SVO)to see if it may improve the performance of empty space ray marching in volumes. While ray marching is a somewhat new technique it is used more often in traversal of volumes. It can be used for realistic volumetric effects in computer games or it can be used in the medical field when examining and visualizing MRI scans.
