Four different ways to detect Kraft and soluble pine lignin using either soluble or immobilised Trametes hirsuta laccase have been investigated. In the first, the concentration of lignin was measured using laccase in homogeneous medium with a Clark electrode. In the second, laccase immobilised onto aminated porous glass beads was used in a reactor submerged into the lignin containing solution and
A chip for digital intermediate frequency filtering is introduced. The filter is intended move most of the analog intermediate frequency filtering to the digital domain in systems like the American mobile radio system (IS-54). It is a wave digital lattice filter realized with bit-serial arithmetic. Furthermore, a technique for local clocks on chip is presented. The method is based on a ring oscill
An external device ("rottometer") specially designed to measure knee joint rotation was developed and evaluated with respect to its validity. Simultaneous measurements were made with the rottometer and Roentgen stereometric analysis (RSA) in five patients with implanted tantalum markers in the tibia and femur. Measurements of internal and external rotation were made at 90 degrees and 60 degrees of
We report experimental oscillator strengths for 88 Ti I transitions covering the wavelength range 465-3892 nm, 67 of which had no previous experimental values. Radiative lifetimes for 13 energy levels, including the low energy levels 3d(2)(F-3) 4s4p ((3)p) z(5)D(j)degrees have been measured using time-resolved laser-induced fluorescence. Intensity-calibrated Ti I spectra have been measured using F
This paper provides an overview of the state-of- the-art radio propagation and channel models for wireless multiple-input multiple-output (MIMO) systems. We distinguish between physical models and analytical models and discuss popular examples from both model types. Physical models focus on the double-directional propagation mechanisms between the location of transmitter and receiver without takin
The shear-induced transitions between an oriented lamellar phase and shear-induced multilamellar vesicles (MLVs) in a nonionic surfactant system were studied by deuterium rheo-NMR spectroscopy as a function of time in start-up experiments at several temperatures and shear rates. By starting from an initial state of oriented lamellae and observing the transformation to the final steady state of MLV
Ovarian cancer is usually found at a late stage when the prognosis is often bad. Relative survival rates decrease with tumor stage or grade, and the 5-year survival rate for women with carcinoma is only 38%. Thus, there is a great need to find biomarkers that can be used to carry out routine screening, especially in high-risk patient groups. Here, we present a large-scale study of 64 tissue sample
The human Simpson-Golabi-Behmel syndrome (SGBS) preadipocyte cell strain provides a unique and useful tool for studies of human adipocyte biology. The cells originate from an adipose tissue specimen of a patient with SGBS. They are neither transformed nor immortalized, and provide an almost unlimited source due to their ability to proliferate for up to 50 generations with retained capacity for adi
The Five Aspects Meal Model (FAMM) is a structured approach towards explaining what makes up an entire meal experience. One aspect in particular, the management control system, has a clear potential of being developed to increase the practical impact of the model. Scholars suggest that the management control system aspect works backstage, where matters of computer work, handling statistics, market
Objectives: To investigate the bactericidal activity of antiviral and anticancer nucleoside analogues against a variety of pathogenic bacteria and characterize the activating enzymes, deoxyribonucleoside kinases (dNKs). Methods: Several FDA-approved nucleoside analogue drugs were screened for their potential bactericidal activity against several clinical bacterial isolates and type strains. We ide
Highly purified plasma membranes from spinach (Spinacia oleracea L.) leaves contained phosphatidylinositol (PtdIns) kinase activity that was firmly associated with the membrane. The enzyme was solubilized by detergent treatment (2% [w/v] Triton X-100) and purified by heparin-Sepharose and Q-Sepharose chromatography. Two enzymically active fractions, QI and QII, both exhibiting PtdIns 4-kinase acti
Objective: While beta(2)-agonists for the acute treatment of preterm labour unequivocally reduce the odds of delivery within 48 hand 7 days, they have been associated with substantial maternal and fetal side effects. We aimed to compare side effect profiles of beta(2)-agonist tocolytics. Study design: Pragmatic comparison of ritodrine, salbutamol and terbutaline from re-analysis of data obtained w
There is a paucity of empirical research on the impact of delirium on professionals' reactions, interpretations or attitudes to people in a delirious state. This is striking because it stands to reason that it is demanding to take care of a person who is disoriented, perhaps agitated and who may hallucinate and/or act in a manner that calls for interventions involving the use of force or actions t
Our purpose is to find factors that are important for expected returns and risk of Swedish industrial portfolios during 1980–1997. The tested factors are supposed to be essential for a small open economy. We take into account the small sample problem that surfaces in the form of firms dominating the value weighted test portfolios. An extreme bound analysis (EBA) investigates the robustness of the
The N-terminal NC4 domain of collagen IX is a globular structure projecting away from the surface of the cartilage collagen fibril. Several interactions have been suggested for this domain, reflecting its location and its characteristic high isoelectric point. In an attempt to characterize the NC4 domain in more detail, we set up a prokaryotic expression system to produce the domain. The purified
The path and termination point for the rp-process above Ni-56 is uncertain due to a tack of knowledge of nuclear properties, especially masses, near the proton drip line. To address this need we have begun a program to measure masses of nuclei along the rp-process pathway in the A similar to 60-80 region using beta-gamma coincidence spectroscopy. Results for Se-71 are presented and a preliminary e
The capture of human acute mycloid leukemia KG-1 cells expressing the CD34 surface antigen and the fractionation of human blood lymphocytes were evaluated on polyvinyl alcohol (PVA)-cryogel beads and dimethyl acrylamide (DMAAm) monolithic cryogel with immobilized protein A. The affinity ligand (protein A) was chemically coupled to the reactive PVA-cryogel beads and epoxy-derivatized monolithic cry
This article discusses known or suspected effects of maternal use of antidepressants during pregnancy on pregnancy outcome. It is unlikely that any marked teratogenic effect occurs with the possible exception of an increased risk for cardiovascular defects after maternal use of clomipramine or paroxetine. An increased risk for preterm birth is seen. Transient neonatal symptoms are common after the
ATP-dependent priming of the secretory granules precedes Ca(2+)-regulated neuroendocrine secretion, but the exact nature of this reaction is not fully established in all secretory cell types. We have further investigated this reaction in the insulin-secreting pancreatic B-cell and demonstrate that granular acidification driven by a V-type H(+)-ATPase in the granular membrane is a decisive step in
It is becoming increasingly evident that single-locus effects cannot explain complex multifactorial human diseases like cancer. We applied the multi-factor dimensionality reduction (MDR) method to a large cohort study on gene-environment and gene-gene interactions. The study (case-control nested in the EPIC cohort) was established to investigate molecular changes and genetic susceptibility in rela
