A β-mannosidase was purified to homogeneity from the culture filtrate of Aspergillus niger. A specific activity of 500 nkat mg−1 and a 53-fold purification was achieved using ammonium sulfate precipitation, anion-exchange chromatography, and gel filtration. The isolated enzyme has an isoelectric point of 5.0 and appears to be a dimer composed of two 135-kDa subunits. It is a glycoprotein and conta

Popular Abstract in Swedish Molybden ingår som en viktig del i två typer av biologiska system - dels i nitrogenas, som fixerar kvävgas ur atmosfären, och dels i de enkärniga molybdenenzymerna. De senare är enzymer som innehåller endast en molybdenatom i sina aktiva säten. De enkärniga molybdenenzymerna finns i en mängd levande system, från bakterier till växter och djur och även i människan. EnzymThe thesis deals with models for molybdopterin-dependent enzymes. Several model systems containing molybdenum or tungsten have been prepared and characterised, and their reactivity with oxygen atom acceptors and donors have been investigated. Oxygen atom transfer reactions involving oxomolybdenum bis-dithiolene complexes have been modelled using density functional calculations. The first molybden

Popular Abstract in Swedish Senpleistocen nedisningshistoria på Nordöstgrönland: kosmogen exponeringsdatering, isutbredning och isdynamik Under den senaste istiden var periodvis stora delar av landmassorna på norra halvklotet istäckta. Idag är den Grönländska inlandsisen den enda större återstoden av detta, men likväl binder den tillsammans med isen i Antarktis och jordens mindre glaciärer väldigtThe aim of this thesis was to use cosmogenic exposure dating to investigating whether highly weathered landscapes in the Northeast Greenland fjord zone have developed during prolonged ice free conditions or have been preserved beneath cold-based ice. Previous work along the Northeast Greenland coast has presented two conflicting hypotheses for the extent of the Greenland Ice Sheet during the last

Abstract in UndeterminedVery large MIMO is a technique that potentially can offer large network capacities in multi-user scenarios where the users are equipped only with single antennas. In this paper we are investigating channel properties for a realistic, though somewhat extreme, outdoor base station scenario using a large array. We present measurement results using a 128 element linear array ba

Background: Development of multiple primary tumors is a hallmark of hereditary cancer. At least 1/10 of breast cancers and colorectal cancers occur because of heredity and recently the cell cycle kinase 2, CHEK2 1100delC allele has been identified at a particularly high frequency in families with hereditary breast and colorectal cancer. Methods: We utilized the Southern Sweden population-based can

The uterine arteries and arteries in the wall and core of myomas were examined with transvaginal color and spectral Doppler ultrasound in 28 premenopausal and 17 postmenopausal women with uterine myomas. Eighteen premenopausal women and 100 postmenopausal women without myomas served as the controls for uterine artery Doppler measurements. The respective median time-averaged maximum velocity and pu

The estimated number of children who are utilised as child soldiers all over the world is 250,000 today. Based on the Coalition to Stop the Use of Child Soldiers research children were used in armed conflicts in 20 countries from 2004-2007. One of the most prominent nations involving the use of child soldiers is the Democratic Republic of the Congo. It is estimated, that 40% of them are girls, who

This study explores the extent to which decentralization has affected farmers’ access to agricultural advisory services in the Sunyani Municipality of Ghana. Specifically, it focuses on how political and organizational factors, which are intermediate outcomes of decentralization, affect the availability and relevance of advisory services. The study follows a qualitative research design employing q

Pion photo production from the nucleon is an important process utilized to understand the structure of the nucleon and the fundamental dynamics of the nucleon system. The neutral pion production has been extensively studied resulting in valuable data sets. However, much less data is available for charged pion photo production at energies below 200 MeV. In order to get a reliable data set for π+, f

BACKGROUND: Cut-points to define slow walking speed have largely been derived from expert opinion. METHODS: Study participants (13 589 men and 5043 women aged ≥65years) had walking speed (m/s) measured over 4-6 m (mean ± SD: 1.20 ± 0.27 m/s in men and 0.94 ± 0.24 m/s in women.) Mobility limitation was defined as any self-reported difficulty with walking approximately 1/4 mile (prevalence: 12.6% me

A novel S-scheme photocatalytic heterojunction composite nanomaterial is developed by integrating zero-dimensional WO3 quantum dots (WQDs) on two-dimensional ultrathin CdIn2S4 (CIS) nanosheets with the aim of fostering carrier separation, enhancing the performance of carrier interface transport, minimizing carrier distance transport, and achieving effective photocatalytic CO2 reduction. The compos

Humanity injects an almost incomprehensible 42 billion tonnes of carbon dioxide (CO₂) into the atmosphere every year. The majority of this comes from burning fossil fuels, but a substantial portion, about 16%, arises from how we use the land. Most of these land-use emissions are caused by deforestation, particularly in the tropics.In order to slow climate change, the global community needs to redu

Two electrotechnologies: pulsed electric fields (PEF) and moderate electric field (MEF) in combination with vacuum impregnation of glycerol as cryoprotectant were used to increase the freezing tolerance of rocket leaves. Rocket leaves were treated with PEF using a nominal field strength of 1200 V/cm or MEF at different combinations of voltage and frequency. Leaves were then immersed in a glycerol

The aim of this study was to develop a novel software platform for the simulation of magnetic resonance spin systems, capable of simulating a large number of spatial points (1283 ) for large in vivo spin systems (up to seven coupled spins) in a time frame of the order of a few minutes. The quantum mechanical density-matrix formalism is applied, a coherence pathway filter is utilized for handling u

Alkaline ion-solvating membranes derived from a tetrazole functionalized poly(arylene alkylene) are prepared, characterized and evaluated as electrode separators in alkaline water electrolysis. The base polymer, poly[[1,1′-biphenyl]-4,4′-diyl(1,1,1-trifluoropropan-2-yl)], is synthesized by superacid catalyzed polyhydroxyalkylation and subsequently functionalized with tetrazole pendants. After equi
