Economies in transition (EiTs) (e. g. Ukraine (UA), Belarus, Lithuania (LU), Moldova, etc.) face broad needs for energy security enhancement, energy diversification, revitalisation of agriculture and improvements in the state of the environment. Development of national bioenergy potentials can contribute to delivering solutions to these problems. However, EiTs face technical, political, financial,

Adsorption dynamics of various types of uncharged homopolymers onto solid surfaces in good solvent have been studied by using a coarse grained bead-spring model. Brownian dynamics simulation has been used to examine the adsorption process for polymers released near an adsorbing surface, and Monte Carlo simulations have been employed to explore equilibrium properties of adsorbed polymers. Two diff

In this study we investigate utterance-final intonation in two dialects of Kammu, one tonal and one non-tonal. While the general patterns of utterance-final intonation are similar between the dialects, we do find clear evidence that the lexical tones of the tonal dialect restrict the pitch range and the realization of focus. Speaker engagement can have a strong effect on the utterance-final accent

Popular Abstract in Swedish Järn är ett metalliskt grundämne som tillhör övergångselementen i det periodiska systemet. Den kemiska beteckningen är Fe (av det latinska ordet ferrum). Järn har visat sig vara ett väldigt viktigt ämne för i princip allt liv på vår planet. Främst finns det bundet till olika proteiner i form av järnsvavelkluster och hem. Hem är en liten molekyl som finns i de allra fleFerrochelatase catalyses the synthesis of heme by inserting Fe(II) into protoporphyrin IX. The structure of ferrochelatase from yeast has been determined (2.4 Å). The structure is homodimeric with each of the monomer made up of two Rossmann type domains with an active-site cleft between them. Metal binding studies with Co(II) and Cd(II) ions reveal the metal binding residues as being the His-Glu

Popular Abstract in Swedish I vår kropp pågår ständigt interaktioner mellan olika molekyler. Det är dessa interaktioner som styr hur vi mår och vad som händer i kroppen. Många av dessa interaktioner är svaga, vilket gör att det krävs många sådana interaktioner samtidigt för att uppnå effekt. Svaga interaktioner är snabba och reversibla, vilket betyder att kroppen snabbt kan anpassa sig efter nya fAn increase in the plasma level of creatine kinase MB (CKMB) has long been used to indicate acute myocardial infarction (AMI). For optimal treatment an early diagnosis is important. An increase in the ratio between the two isoforms of CKMB is seen much earlier than an increase in the total level of CKMB. One possible method for separating these isoforms could be weak affinity chromatography (WAC).

Experimental oscillator strenghts (f-values) for lines in Zr II and Cr II have been determined using branching fractions (BFs) and radiative lifetimes. Experimental log gf-values for 263 spectral lines in Zr II have been derived by combining previously measured lifetimes with new BFs measured on the Lund UV Fourier Transform Spectrometer (FTS). The oscillator strengths have been used to determine

To the extent that increased urinary protein excretion is an indicator of alterations of the glomerular capillary wall (GCW) and appearance of tubulointerstitial damage, proteinuria can be a good marker of the overall severity of the glomerular and tubulointerstitial damage, and therefore, the prognosis of glomerular diseases. Studies I, II, and III show that it is the type of proteinuria, rather

The rapid growth of traffic induced by Internet services makes the simple over-provisioning of resources not economical and hence imposes new requirements on the dimensioning methods. Therefore, the problem of network design with the objective of minimizing the cost and at the same time solving the tradeoff between maximizing the service data flows and providing fair treatment of all demands becom

The article analyses in a historical perspective how ideas of Europe are discussed in Baltic intellectual, political and scholarly debates, and how the Baltic republics are positioned in these debates.

Abstract in UndeterminedEdge sealing is often used to assure one-dimensional moisture flow and a defined exposure area in moisture transport experiments. This paper deals with the performance of a number of edge sealing systems including wax-paraffin mix, epoxy adhesive, silicone and different tapes and films. The overall performance of the sealing systems includes vapor permeability and hygroscop

Kaposi's sarcoma-associated herpes virus (KSHV) encodes a complement inhibitor named KSHV complement control protein (KCP). We have previously shown that KCP inhibits the human complement system by disrupting the C3 convertase of complement. KCP can accelerate the decay of the classical C3 convertase and it can act as a cofactor for factor I (R), which then cleaves and inactivates C4b or C3b (in t

Monumental Past is a living text based on a doctoral dissertation submitted by Cornelius J. Holtorf to the University of Wales in 1998. It explores the social and cultural meanings of megaliths from later prehistoric Mecklenburg-Vorpommern located in northeastern Germany. The author engages directly with current debates about the significance of monuments, events and processes in their life histo

Popular Abstract in Swedish Svensk sammanfattning Inflammation är kroppens svar på yttre störning. Det inflammatoriska svaret är nödvändigt för att bekämpa infektioner, t.ex. med bakterier. Å andra sidan orskar det inflammatoriska svaret mycket skada när det aktiveras utan närvaro av infektioner, tex vid astma, reumatism, blodförgiftning och inflammatorisk tarmsjukdom. Akut inflammation karaktäriMigration of leukocytes from the circulating blood into the extravascular tissue is a key component in inflammatory reactions. Leukocyte extravasation (rolling-activation-adhesion-transmigration) is strictly coordinated by adhesion molecules and chemokines expressed on cell surfaces and in tissues. Tumor necrosis factor-alpha (TNF-alpha) is pleiotrophic cytokine, which plays an important role in t
