Laccase production by Galerina sp. and its application in dye decolorization

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

A new severe plastic deformation method : Twist extrusion

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

On the Stability of the Nystrom Method for the Muskhelishvili Equation on Contours with Corners

The stability of the Nystrom method for the Muskhelishvili equation on piecewise smooth simple contours Gamma is studied. It is shown that in the space L-2 the method is stable if and only if certain operators A tau(j) from an algebra of Toeplitz operators are invertible. The operators A tau(j) depend on the parameters of the equation considered, on the opening angles theta(j) of the corner points

Galiellalactone induces cell cycle arrest and apoptosis through the ATM/ATR pathway in prostate cancer cells.

Galiellalactone (GL) is a fungal metabolite that presents antitumor activities on prostate cancer in vitro and in vivo. In this study we show that GL induced cell cycle arrest in G2/M phase, caspase-dependent apoptosis and also affected the microtubule organization and migration ability in DU145 cells. GL did not induce double strand DNA break but activated the ATR and ATM-mediated DNA damage resp

Gröbner Basis Approach to Some Combinatorial Problems

We consider several simple combinatorial problems and discuss different ways to express them using polynomial equations and try to describe the Gröbner basis of the corresponding ideals. The main instruments are complete symmetric polynomials that help to express different conditions in rather compact way.

Features of the Nyström method for the Sherman-Lauricella equation on Piecewise Smooth Contours

The stability of the Nyström method for the Sherman-Lauricella equation on contours with corner points $c_j$, $j=0,1,...,m$ relies on the invertibility of certain operators $A_{c_j}$ belonging to an algebra of Toeplitz operators. The operators $A_{c_j}$ do not depend on the shape of the contour, but on the opening angle $\theta_j$ of the corresponding corner $c_j$ and on parameters of the approxim

Modern War on an Ancient Battlefield: The Diffusion of Military Technology and Ideas in the Chinese Civil War, 1946-49

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

Variability in the G3 domain content of bovine aggrecan from cartilage extracts and chondrocyte cultures

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

Real-Time Volumetric Lighting using SVOs

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.

Internal branding vid svenska fakulteter

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

Catch the dream of financial independence - A study about how you can impact your retirement saving and reach your future financial goal

This paper takes off in the rapidly growing fields of financial independence and financial literacy. We develop a model focusing on reaching financial independence during retirement and mitigate financial decision making for financially illiterate. The model is based on theoretical research within financial literacy, economic life-cycle and safe withdrawal rates. To ensure qualified monthly saving

Sociala hänsyn i offentlig upphandling - mot bakgrund av det nya EU-direktivet

Det nya direktivet om offentlig upphandling, Europaparlamentets och rådets direktiv 2014/24/EU, ska implementeras i svensk rätt senast år 2016. Denna uppsats behandlar det nya direktivets betydelse för möjligheterna att ställa krav på sociala hänsyn. Det innefattar även den utveckling som har skett på området sociala hänsyn i övrigt. Direktivet innebär inga större förändringar avseende sociala häThe new directive on public procurement, the European Parliament and Council Directive 2014/24/EU, is to be implemented in Swedish law by the year 2016. This paper discusses the new directive’s significance for opportunities to make demands on social considerations. It also includes the development that has taken place in the area of social considerations in general. The directive involves no maj

What about disposition? Exploring millennials’ clothing disposal behaviours in fashion-oriented impulse buying.

The frequent restocking of stores and constant promotional offers associated with fast fashion presents the physical cues for consumers to engage in fashion-oriented impulse buying. This consumption behaviour has led to over consumption and the underutilization of clothes, adding to the problems of textile waste all over the world. Despite the increasing interest in consumers’ disposition behaviou
