The electrochemical behavior and the electrocatalytic activity for the NADH oxidation at glassy carbon paste electrodes (GCPEs) modified with Meldola Blue (MB) adsorbed onto acidic cc-zirconium phosphate (ZP*) have been investigated. Cyclic voltammetry and rotating disc electrode measurements, performed in Tris buffer solution (pH 7) in absence and in presence of different NADH concentrations, sho

Thiobacillus ferrooxidans and Acidianus brierleyi were capable of oxidizing pure pyrite as well as oxidizing sulfur in coal. First order reactions were assumed in the kinetic analysis performed. For oxidation of pure pyrite the rate constant was higher for A. brierleyi than for T. ferrooxidans. For sulfur removal from coal the values of the rate constants were comparable far the two microorganisms

Background: Only limited information is available on healthy young women's perspective of their own lifestyle behaviours. By lifestyle behaviours, e.g. smoking and physical activity, individuals have the possibility to influence bone mineral density (BMD). The aim of this study was to generate a theoretical model of lifestyle behaviours among young women with different BMD changes. Methods: Dat

Near-infrared dispersed fluorescence measurements of 13 different atomic multiplets of neutral atomic fragments from photon induced neutral dissociation processes in NO are reported. For excitation of the molecules narrow band synchrotron photons of energy 17.2-25.8 eV were used. Neither Rydberg series nor other molecular states in NO known so far can account for the collected data. From ab initio

Objectives To describe the endosonographic image of the anal sphincter 2-7 days after delivery in women who had undergone a primary repair of an obstetric sphincter tear. Methods Forty-eight women who had suffered a third- or fourth-degree sphincter tear at delivery and had undergone primary sphincter repair were examined with endoanal sonography 2-7 days after delivery. A score from 0 to 16 was

Genetic engineering has been used to construct hydrophobically modified fusion proteins of cutinase from Fusarium solani pisi and tryptophan-containing peptides. The aim was to enhance the partitioning of the tagged protein in a novel aqueous two-phase system formed by only one water-soluble polymer. The system was based on a hydrophobically modified random copolymer of ethylene oxide (EO) and pro

By using an experimental setup yielding the acoustical Two-Port properties of earplugs. the attenuation of three fundamentally different types of earplugs is predicted. The setup used is based on molds of the ear canals of a real person, and the Two-Port of each earplug is numerically coupled to an acoustical model of the ear. The predicted attenuation is compared to the subjective attenuation (RE

We investigate spin-dependent transport properties of a two-terminal electron waveguide, attached with a side arm, with Rashba spin-orbit interaction (SOI). The interference between the bound states in the side arm and the continuous states in the straight channel gives rise to broad valleys in the conductance spectrum. At these Fano antiresonances, a large transverse spin polarization can be crea

Popular Abstract in Swedish I avhandlingen behandlas tre texter av den tjeckiske författaren Bohumil Hrabal (1914–1997): ”Mrtvomat” (från 1949), Denna stad är i invånarnas gemensamma vård (från 1967) och ”Legend spelad på strängar spända mellan vaggan och kistan” (från 1968). Alla tre texterna är sammanställda av textsegment valda ur andra författares verk och av fragment av avlyssnade samtal. HraThe main theme of the thesis is an analysis of three texts by the Czech author Bohumil Hrabal (1914 – 1997), namely ’Mrtvomat’ (’Mrtvomat’, 1949), This City is in the Joint Care of Its Inhabitants (Toto mìsto je ve spoleèné péèi obyvatel, 1967), and ’Legend Played on Strings Stretched Between the Cradle and the Coffin’ (’Legenda zahraná na strunách mezi kolébkou a rakví’, 1968). These texts are co

Denna rapport behandlar fuktskador i ett hus uppfört 1973 med platta på mark och flytande golv. Mätningar har genomförts i huset under två år. Syftet var att erhålla mätdata under en lång tidsperiod i en byggnad med klara fukt- och luktproblem. I rapporten diskuteras lämpliga åtgärder för att komma till rätta med problemen.

In this study, we show that distinct compartmentalization patterns of the IL-1 molecules (IL-1alpha and IL-1beta), in the milieu of tumor cells that produce them, differentially affect the malignant process. Active forms of IL-1, namely precursor IL-1alpha (pIL-1alpha), mature IL-1beta (mIL-1beta), and mIL-1beta fused to a signal sequence (ssIL-1beta), were transfected into an established fibrosar

Context: T-3 action in neurons is essential for brain development. Recent evidence indicates that monocarboxylate transporter 8 (MCT8) is important for neuronal T-3 uptake. Hemizygous mutations have been identified in the X-linked MCT8 gene in boys with severe psychomotor retardation and elevated serum T-3 levels. Objective: The objective of this study was to determine the functional consequences

Fast line relaying algorithms are motivated by the need to keep the fault clearing time as short as possible. Fast fault clearing reduces the risk for transient instability, thermal stress on equipment and risk for personnel injuries. There exists, at least, three different themes in transmission line protection: impedance algorithms differential equation algorithms (DEA); and travelling wave algo

Problem med mikrobiell påväxt på fasader har ökat kraftigt på senare tid. Redan något år efter putsningen av en fasad har kraftig påväxt kunnat konstateras. En pilotstudie har genomförts av LTH i samverkan med JM AB och NCC Teknik, med stöd av SBUF och den visar att mögelpåväxten har samband med t ex fasadens utformning, ytans struktur, väggens värmeisolering och framför allt dess värmekapacitet.

Cubomedusae, or box jellyfish, have the most elaborate visual system of all cnidarians. They have 24 eyes of four morphological types, distributed on four sensory structures called rhopalia. Box jellyfish also display complex, probably visually guided behaviors such as obstacle avoidance and fast directional swimming. Here we describe the strikingly complex and partially bilaterally symmetrical ne

We analyzed the reactivity of three different commercially available rat monoclonal antibodies raised against mouse laminin-a1 beta 1 gamma 1 (laminin-11), AL-1, AL-2, and AL-4. Using ELISA assays, Western blot analysis and inummostainings we present refined epitope maps for these three laminin monoclonals. AL-1 reacted, as predicted with laminin alpha 1 chain. AL-4 has also been marketed as an al

Endoglucanases (EGI) (endo-1,4-β-d-glucan-4-glucanohydrolase, EC 3.2.1.4, Cel7B) of Trichoderma reesei are industrially important enzymes. Thus, there is a great need for development of a primary recovery method suitable for large-scale utilization. In this study we present a concept applicable for large-scale purification of an EGI fusion protein by one-step extraction in a poly(ethylene glycol)
